RESUMEN

PURPOSE: This study analyzes levels of social participation in patients with breast cancer on average 5 years following primary surgery as compared to women in the general population. In addition, the role of breast cancer-related complaints and medical data as possible influencing factors on levels of patients' social participation is investigated. METHODS: A total of n = 454 patients after primary surgery (t0) were recruited for a third follow-up study, and n = 372 completed this survey (t3), corresponding to a response rate of 82.2%. For measuring breast cancer-related complaints, participants completed a written questionnaire. Social participation was measured by a questionnaire on different leisure activities that was taken from the Socio-Economic Panel Study. Medical information was extracted from medical reports at t0. A principal component analysis was carried out to identify different dimensions of social participation. Chi2-tests and logistic regression analyses were applied to analyze social participation as compared to the general population and the role of possible medical and diagnosis-related influencing factors thereby. RESULTS: Compared to the general population, patients show lower levels of social participation in the domains "socio-cultural participation" and "participation in institutions," while no significant differences for "social participation in the private sphere" and "social participation via social media" were found. Psychological symptoms, pain, and a history of mastectomy were most strongly associated with restrictions in social participation. CONCLUSIONS: Our study suggests that social withdrawal may happen due to disease-related symptoms, preventing some breast cancer patients from participating fully in society. Cancer-related follow-ups should address this issue and support patients' reintegration into society through appropriate therapeutic interventions.

RESUMEN

PURPOSE: Data reported on comparing primary and revisional procedures in the elderly is still limited. The aim of this study was to compare the efficacy and safety between primary and revisional bariatric surgery in a cohort of older patients. MATERIALS AND METHODS: All patients ≥ 60 years old were divided into two cohorts, primary surgery cohort (PSC) and revisional surgery cohort (RSC). Baseline and perioperative outcomes were analyzed. RESULTS: Fifty-eight patients were included (34 PSC and 24 RSC) in the study. Forty-two (25 PSC and 17 RSC) 72.4% were female. The mean age was 64 (± 3.3 years) in the PSC and 65 (± 4.2 years) in the RSC, the median initial BMI was 46.7 and 47.4 kg/m2 (p < 0.848), respectively. The mean hospital stay was (3 PSC vs. 5 RSC, p < 0.022) days. Readmissions occurred in (1 PSC vs. 3 RSC, p = 0.158) patients within 30 days of discharge. Postoperative major complications included (1 PSC vs. 5 RSC, p < 0.0278) patients. Reoperations were reported in (0 PSC vs. 3 RSC, p < 0.034) patients. Patients who underwent surgery for weight management, the initial mean BMI was (46.7 PSC vs. 47.4 RSC kg/m2, p = 0.848). At 12-months post-procedure, the mean BMI was (34.3 PSC vs. 37.7 RSC kg/m2, p = 0.372) and (23.7 PSC vs. 19.1 RSC, p = 0.231) %TBWL. The mean overall follow-up was (12.4 PSC vs. 27.5 RSC, p < 0.004) months, and one unrelated death (cancer) was reported in the RSC. CONCLUSION: PSC and RSC are effective in the elderly, however postoperative complications occurred more often in the RSC group.

RESUMEN

CONTEXT: Contemporary patients with primary hyperparathyroidism are diagnosed with milder disease than previously. Clinical and biochemical factors predictors with impact on fracture incidence and bone mineral density after surgery have not been firmly established. OBJECTIVE: To investigate predictors of fracture incidence and bone mineral density preoperatively and after surgery for primary hyperparathyroidism (pHPT). DESIGN: Prospectively collected surgical cohort with matched population controls. Data were cross-linked with the Swedish National Patient Register, the Prescribed Drug Register, and the Cause of Death Register. SETTING: Tertiary referral center. PATIENTS OR OTHER PARTICIPANTS: 709 patients with successful parathyroidectomy for pHPT, and 2,112 controls matched on sex, age, and municipality were included in the study. MAIN OUTCOME MEASURES: Fracture incidence, absolute change and ≥2.77% increase in bone mineral density of femoral neck, L2-L4 and distal third of radius at 1-year follow-up. RESULTS: Patients with pHPT had an increased fracture incidence before surgery but not after pHPT surgery. Fracture incidence after surgery was inversely related to preoperative 24-hour urine calcium (IRR for the highest tertile 220- mg/d 0.29, CI 95% 0.11-0.73). Serum and 24-hour urine calcium, parathyroid hormone, osteocalcin and adenoma weight were all associated with bone mineral density recovery after surgery. CONCLUSIONS: 24-hour urine calcium is the most important biochemical variable to predict a decreased fracture incidence and improved bone mineral density after surgery for pHPT.

RESUMEN

OBJECTIVE: To determine the relationship between pre-operative HE4 and CA125 levels in non-mucinous epithelial ovarian cancer cases (EOC) and outcomes of primary surgery for prediction of optimal surgery. METHODS: A retrospective study was performed on non-mucinous EOC who underwent primary surgery at King Chulalongkorn Memorial Hospital from 2016 to 2020. Demographic and clinical characters were collected. Histopathology and pre-operative tumor markers namely HE4 and CA125 were also recruited. Primary surgical outcomes were classified as optimal (OS) and suboptimal surgery (SS). RESULTS: One hundred and seventy patients were enrolled in the study. There were 130 and 40 cases in OS and SS, respectively. Average age and body mass index (BMI) of EOC were 54.2 years old and 23.1 Kg/m2, respectively. Both groups had comparable demographic characteristics. Two-thirds (103/170) and one-third (63/170) had early stage and clear cell histopathology, respectively. The median level of HE4 were 118.60 and 603.45 pmol/L in OS and SS, respectively. OS and SS had average CA125 at 146.95 and 814.70 U/L, respectively. The best cut-off point of HE4 and CA125 less than 170.95 pmol/L and 316.4 U/mL gave predicting OS with area under curve (AUC) at 0.78 and 0.75, respectively. HE4 and CA125 cut-off point had sensitivity, specificity, positive predict value (PPV) and negative predictive value (NPV) at percentage of 60.8/60.8, 87.5/82.5, 94.1/91.9 and 40.7/39.3, respectively. CONCLUSION: HE4 and CA125 of non-mucinous EOC among OS had significantly less than SS and could be the predicting of optimal surgery.

RESUMEN

INTRODUCTION: Colorectal cancer (CRC) creates elevated self-management demands and unmet support needs post-discharge. Follow-up care through eHealth post-primary surgery may be an effective means of supporting patients' needs. This integrative review describes the evidence regarding eHealth interventions post-hospital discharge focusing on delivery mode, user-interface and content, patient intervention adherence, impact on patient-reported outcomes and experiences of eHealth. METHODS: A university librarian performed literature searches in 2021 using four databases. After screening 1149 records, the authors read 30 full-text papers and included and extracted data from 26 papers. Two authors analysed the extracted data using the 'framework synthesis approach'. RESULTS: The 26 papers were published between 2012 and 2022. The eHealth interventions were mainly delivered by telephone with the assistance of healthcare professionals, combined with text messages or video conferencing. The user interfaces included websites, applications and physical activity (PA) trackers. The interventions comprised the monitoring of symptoms or health behaviours, patient information, education and counselling. Evidence showed a better psychological state and improved PA. Patients reported high satisfaction with eHealth. However, patient adherence was inadequately reported. CONCLUSIONS: eHealth interventions may positively impact CRC patients' anxiety and PA regardless of the user interface. Patients prefer technology combined with a human element.

RESUMEN

PURPOSE: Surgeons want to achieve native kinematics in primary total knee arthroplasty (TKA). Cruciate-substituting (CS) implants could restore the knee kinematics more efficiently than posterior-stabilised (PS) TKA. This study aimed to compare gait patterns in patients with CS or PS TKA at 6 months. The hypothesis was that CS implants would demonstrate comparable gait parameters to PS implants at 6 months. METHODS: In this prospective case-control study, 38 primary TKA without coronal laxity were divided into 2 groups: 19 cruciate-substituting (CS) and 19 posterior-stabilised (PS) implants. The type of prosthesis was determined according to the surgical period. Exclusion criteria were TKA revision, associated procedures and inability to walk on a treadmill. Gait analysis was conducted on a treadmill 6 months postoperatively for each patient with a knee assessment device (KneeKG®). Gait characteristics included analysis in three spatial dimensions (flexion-extension, abduction-adduction, internal-external rotation, anterior-posterior translation). Clinical outcomes (Knee Society Score and Forgotten Joint Score) were compared between both groups at 6 months postoperatively. RESULTS: At 6 months, the gait analysis did not demonstrate any significant difference between CS and PS implants. The range and the maximum anteroposterior translation were similar in both groups (9.2 ± 6.5 mm in CS group vs. 8.1 ± 3 mm in PS group (n.s.); and - 5.2 ± 5 mm in CS group vs. - 6.3 ± 5.9 mm in PS group (n.s.), respectively). The internal/external rotation, the flexion, and the varus angle were similar between CS and PS implants. The KSS Knee score was higher at 6 months in the CS group than in the PS group (92.1 ± 5.6 vs. 84.8 ± 8.9 (p < 0.01)). CONCLUSION: Cruciate-substituting and posterior-stabilised TKA had similar gait patterns at 6 months postoperatively, despite a non-equivalent posterior stabilisation system. CS prostheses were an interesting option for primary TKA for knee kinematics restoration without requiring a femoral box. LEVEL OF EVIDENCE: Prospective, case-control study; Level II.

RESUMEN

BACKGROUND: Total knee arthroplasties (TKAs) for patients aged ≤35 years are rare but necessary for patients who have diseases such as juvenile idiopathic arthritis, osteonecrosis, osteoarthritis, and rheumatoid arthritis. Few studies have examined the 10-year and 20-year survivorship and clinical outcomes of TKAs for young patients. METHODS: A retrospective registry review identified 185 TKAs in 119 patients aged ≤ 35 years performed between 1985 and 2010 at a single institution. The primary outcome was implant survivorship free of revision. Patient-reported outcomes were assessed at 2 time points: 2011 to 2012 and 2018 to 2019. The average age was 26 years (range, 12 to 35). Mean follow-up was 17 years (range, 8 to 33). RESULTS: Survivorship decreased from 84% (95% confidence interval [CI]: 79 to 90) at 5 years to 70% (95% CI: 64 to 77) at 10 years and to 37% (95% CI: 29 to 45) at 20 years. The most common reasons for revision were aseptic loosening (6%) and infection (4%). Risk factors for revision included increasing age at time of surgery (Hazards Ratio [HR] 1.3, P = .01) and use of constrained (HR 1.7, P = .05) or hinged prostheses (HR 4.3, P = .02). There were 86% of patients reporting that their surgery resulted in "a great improvement" or better. CONCLUSION: Survivorship of TKAs in young patients is less favorable than expected. However, for the patients who responded to our surveys, TKA demonstrated substantial pain relief and improvement in function at 17-year follow-up. Revision risk increased with older age and higher levels of constraint.

RESUMEN

OBJECTIVES: To study the risk factors of poor wound healing after primary cleft palate surgery. METHODS: In this study, 980 cases of congenital cleft palate treated by Sommerlad-Furlow in the Department of Cleft Lip and Palate Surgery of Sichuan University from 2017 to 2021 were continuously analyzed. Indicators included patient's age, gender, body weight, cleft palate type, width of the widest fistula, cleft palate index (width of the widest fistula/width at the posterior edge of the maxillary tubercle plane), preoperative white blood cell count, preoperative hemoglobin level, preoperative antibiotic use, doctor's seniority, use of relaxation incision, operation time, postoperative upper respiratory tract infection, and postoperative wound healing. The postoperative wound healing was divided into normal healing, delayed healing, and palatal fistula. Both delayed healing and palatal fistula were classified as poor healing. The factors that may affect the healing outcome of the palatal wound after primary cleft palate repair were analyzed using SPSS 26.0 software. RESULTS: A total of 825 patients (84.2%) had normal healing, 112 patients (11.4%) had delayed hea-ling, and 43 patients (4.4%) had palatal fistula. Doctor's seniority, width of the widest fissure, cleft palate index, and operation time influenced the wound healing effect after cleft palate surgery (P<0.05). Doctors with low seniority, wide width of the widest fistula, large cleft palate index, and long operation time were the risk factors of poor wound healing. CONCLUSIONS: Doctor's seniority, width of the widest fissure, cleft palate index, and operation time are related to the effect of healing effect after cleft palate surgery.

RESUMEN

OBJECTIVE: Few studies have investigated the differences in outcomes between primary and repeat surgery for a craniopharyngioma in adults. As a result, a treatment concept for adult patients with a craniopharyngioma has not yet been established. The present study aimed to retrospectively analyze adult patients with craniopharyngioma to compare surgical outcomes between primary surgery and surgery for recurrence. METHODS: The demographic and clinical data of 68 adult patients with craniopharyngioma who had primary surgery (n=50) or surgery for recurrence (n=18) were retrospectively analyzed. In addition, the patients were followed up for an average of 38.6 months (range: 1-133 months). RESULTS: The cohorts of patients undergoing primary surgery or repeat surgery did not differ preoperatively in terms of demographic data, or radiological tumor features. However, patients with recurrent craniopharyngioma had significantly more pituitary hormone deficits and hypothalamo-pituitary disorders before surgery compared with patients with newly diagnosed craniopharyngioma. The success rate of complete resection in primary surgery was 53.2%. Even after repeat surgery, a satisfactory rate of complete resection of 35.7% was achieved. Operative morbidity was increased neither in patients with repeat surgery compared with those with primary surgery (postoperative bleeding P=0.560; meningitis P=1.000; CSF leak P=0.666; visual disturbance P=0.717) nor in patients with complete resection compared with those with partial resection. We found no difference in recurrence-free survival between initial surgery and repeat surgery (P=0.733). The recurrence rate was significantly lower after complete resection (6.9%) than after partial resection (47.8%; P<0.001). CONCLUSION: Attempting complete resection is justified for not only those with newly diagnosed craniopharyngioma but also for those with recurrent craniopharyngioma. However, the surgeon must settle for less than total resection if postoperative morbidity is anticipated.

RESUMEN

Background: The current therapy of ovarian cancer is based on the so-called "Three-Pillar-Model", consisting of surgery, chemotherapy and maintenance therapy. This study represents the first major analysis of a federal cancer database of OC patients from the states Berlin/Brandenburg in Germany. The primary objective was to evaluate the prevailing established quality indicators surgical outcome, adjuvant chemotherapy and integrity of surgical staging in early stages. Methods: Data from the Clinical Cancer Registry for Brandenburg and Berlin of the years 2009−2019 were analyzed. Objectives were defined by a working group of selected physicians. Descriptive statistics were performed, as well as survival analysis. Results: A total of 2771 primary OC cases were included. Results regarding histological subtype met the suspected allocation with predominantly high-grade serous OC in advanced stage. The rate of complete surgical staging in FIGO stages I−IIA was 57%, and the rate of macroscopic complete resection in >FIGO III was 53%. Five-year survival rate varied from 79% (FIGO I) to 40% (FIGO III). Rate of adjuvant chemotherapy was above 50%. Conclusion: The results elucidate quality measurements and treatment results and show good treatment outcomes in patients with primary diagnosis. However, they also indicate deficits and can help to establish new quality indicators to further improve the treatment.

RESUMEN

INTRODUCTION: Desire to homogenize advanced stage ovarian cancer management has led to a debate on the need to centralize cares. The aim was to assess current practices to compare them with centralization motivation and to overview possible perspectives of evolution. METHODS: An anonymous questionnaire of 57 questions has been submitted from August 2021 to October 2021 to members of French gynecological oncological surgical societies. Questions encompassed all aspects of ovarian cancer surgical management, including institutions, technics, indications, and outcomes. RESULTS: Of the 40 responses, 77.5% managed less than 20 cases by themselves, but 67.5% practiced in institution managing more than 30 cases annually. Since the LION trial results' publication, 95% of practitioners have evolved their lymphadenectomy indications. More than 10% of surgery needed digestive resection for 90% of practitioners. Digestive resections rate was significantly higher for practitioners managing more than 20 cases (p<0.01), but it was not for institutions managing more than 30 cases annually (p=0,07). Surgeons performing more than 20 ovarian cancers annually reported less severe complications (p=0.04) compared to low-volume surgeons independently of institution volume. For more than a quarter of the practitioners, less than half of the patients can benefit from the enhanced recovery after surgery program despite benefits of such care. CONCLUSION: Our survey provides an overview of French practices in ovarian cancer management. This survey seems to confirm that minimum volume thresholds could lead to better outcomes. It also underlines that individual performances are as valuable as center volume.

RESUMEN

The present study aimed to evaluate the postoperative complications and the impact of an enhanced recovery programme in patients who underwent primary surgery (including extensive upper abdominal surgery) for epithelial ovarian carcinoma (EOC). All patients with stage I-IV ovarian carcinoma who underwent primary surgery were identified, and postoperative complications were evaluated and graded according to the Clavien-Dindo classification. Of 161 patients, 46 (28.57%) underwent surgical staging, 27 (16.77%) standard cytoreduction, 12 (7.45%) en bloc debulking and 76 (47.20%) extraradical debulking. A total of 157 patients (97.52%) achieved optimal tumor reduction (<1 cm). The mean postoperative hospitalization time was 17.33±11.29 days after completion of the initial postoperative chemotherapy (IPC), and the IPC interval was 16.22±10.09 days. A total of 13 patients (8.07%) had grade 3 complications (9 with wound dehiscence, 3 with digestive tract leakage and 1 with a bladder fistula). A total of 2 patients (1.24%) had grade 4-5 complications [1 patient with severe pneumonia returned to the intensive care unit (ICU) for tracheotomy and respiration rehabilitation; the other patient died of septicemia on day 19]. The multivariate analysis of the preoperative factors revealed that a human epididymis protein 4 (HE4) level of ≥717 pM (P=0.015) and Federation International of Gynecology and Obstetrics (FIGO) stage IV (P=0.004; compared with stage IIIC) were associated with grade 3-5 complications. The bootstrap analysis revealed that a cancer antigen 125 (CA125) level of ≥1,012 U/ml (P=0.034), a HE4 level of ≥717 pM (P=0.007) and FIGO stage IV (P=0.002; compared with stage IIIC) were significantly associated with grade 3-5 complications. Meanwhile, the multivariate analysis of the postoperative factors did not reveal any risk factors associated with grade 3-5 complications; the bootstrap analysis revealed that only transfer to the ICU after surgery (P=0.026) was significantly associated with grade 3-5 complications. In conclusion, the study found that application of enhanced recovery after surgery protocols is feasible in patients with EOC, especially in those undergoing advanced extensive upper abdominal surgery, and CA125, HE4 and FIGO stage IV were related with the occurrence of adverse perioperative outcomes.

RESUMEN

AIMS: Lumbar disc prolapse is a frequent indication for surgery. The few available long-term follow-up studies focus mainly on repeated surgery for recurrent disease. The aim of this study was to analyze all reasons for additional surgery for patients operated on for a primary lumbar disc prolapse. METHODS: We retrieved data from the Swedish spine register about 3,291 patients who underwent primary surgery for a lumbar disc prolapse between January 2007 and December 2008. These patients were followed until December 2020 to record all additional lumbar spine operations and the reason for them. RESULTS: In total, 681 of the 3,291 patients (21%) needed one or more additional operations. More than three additional operations was uncommon (2%; 15/906). Overall, 906 additional operations were identified during the time period, with a mean time to the first of these of 3.7 years (SD 3.6). The most common reason for an additional operation was recurrent disc prolapse (47%; 426/906), followed by spinal stenosis or degenerative spondylolisthesis (19%; 176/906), and segmental pain (16%; 145/906). The most common surgical procedures were revision discectomy (43%; 385/906) and instrumented fusion (22%; 200/906). Degenerative spinal conditions other than disc prolapse became a more common reason for additional surgery with increasing length of follow-up. Most patients achieved the minimally important change (MIC) for the patient-reported outcomes after the index surgery. After the third additional spinal operation, only 20% (5/25) achieved the MIC in terms of leg pain, and 29% (7/24) in terms of the EuroQol five-dimension index questionnaire visual analogue scale. CONCLUSION: More than one in five patients operated on for a lumbar disc prolapse underwent further surgery during the 13-year follow-up period. Recurrent disc prolapse was the most common reason for additional surgery, followed by spinal stenosis and segmental pain. This study shows that additional operations after primary disc surgery are needed more frequently than previously reported, and that the outcome profoundly deteriorates after the second additional operation. The findings from this study can be used in the shared decision-making process. Cite this article: Bone Joint J 2022;104-B(5):627-632.

RESUMEN

Sutureless closure has been used for primary repair of total anomalous pulmonary venous connection (TAPVC) for over 20 years but its superiority over conventional technique is still uncertain. This systematic review was conducted to compare the effectiveness of sutureless closure and conventional surgery as the primary repair for TAPVC. Systematic search was performed in June 2021 on 12 databases. All studies comparing sutureless and conventional surgery for TAPVC were included. The primary endpoints were early mortality, overall mortality, postoperative pulmonary venous stenosis (PVS), and reoperation. Meta-analysis of two-arm studies was performed with several sensitivity and subgroup analyses. Six retrospective studies with 767 patients were included in meta-analyses. Sutureless closure significantly reduced the risk of early mortality, overall mortality, postoperative PVS, and reoperation by 53%, 45%, 77%, and 67% compared to conventional technique, respectively. No heterogeneity was found and presence of publication bias was non-significant. The results were consistent in all sensitivity analyses. Subgroup analyses revealed that sutureless closure was superior to conventional technique in patients with and without preoperative pulmonary venous obstruction, and neonates and non-neonates. Sutureless closure is better than conventional closure as the primary surgery for TAPVC patients. We advocate using sutureless closure for patients with TAPVC. Future large-scale observational studies or clinical trials are required to confirm our findings.

RESUMEN

BACKGROUND: There is uncertainty with regard to the optimal revision procedure after failed labral repair for anterior shoulder instability. An overview of outcomes of these procedures with quantitative analysis is not available in literature. The aim of this review is (1) to compare recurrence rates after revision labral repair (RLR) and revision bony reconstruction (RBR), both following failed labral repair. In addition, (2) recurrence rates after RBR following failed labral repair and primary bony reconstruction (PBR) are compared to determine if a previous failed labral repair influences the outcomes of the bony reconstruction. METHODS: Randomized controlled trials and cohort studies with a minimum follow-up of 2 years and reporting recurrence rates of (1) RBR following failed labral repair and PBR and/or (2) RLR following failed labral repair and RBR following failed labral repair were identified by searching PubMed, Embase/Ovid, Cochrane Database of Systematic Reviews/Wiley, Cochrane Central Register of Controlled Trials/Wiley, and Web of Science/Clarivate Analytics. RESULTS: Thirteen studies met the inclusion criteria and comprised 1319 shoulders. Meta-analyses showed that RBR has a significantly higher recurrence rate than PBR (risk ratio [RR] 0.51, P < .008) but found no significant difference in the recurrence rates for RLR and RBR (RR 1.40, P < .49). Also, no significant differences were found between PBR and RBR in return to sport (RR 1.07, P < .41), revision surgery (RR 0.8, P < .44), and complications (RR 0.84, P < .53). Lastly, no significant differences between RLR and RBR for revision surgery (RR 3.33, P < .19) were found. CONCLUSION: The findings of this meta-analyses show that (1) RBR does not demonstrate a significant difference in recurrence rates compared with RLR and that (2) RBR has a significantly higher recurrence rate than PBR.

RESUMEN

OBJECTIVE: The indication of surgery in primary hyperparathyroidism has been controversial, as many patients experience mild disease. The primary aim was to evaluate fracture incidence in a contemporary population-based cohort of patients having surgery for primary hyperparathyroidism. The secondary aim was to investigate whether preoperative serum calcium, adenoma weight or multiglandular disease influence fracture incidence. DESIGN: A retrospective cohort study with population controls. Primary outcomes, defined by discharge diagnoses and prescriptions, were any fracture and fragility fracture, secondary outcomes were multiple fractures anytime and osteoporosis. Subjects were followed 10 years pre- and up to 10 years postoperatively (or 31 December 2015). Multiple events per subject were allowed. Fracture incidence rate ratios (IRRs) for patients pre- and postoperatively were tabulated and evaluated with mixed-effects Poisson regression. Secondary outcomes were evaluated using conditional logistic regression. PATIENTS: A Swedish nationwide cohort of patients having surgery for primary hyperparathyroidism (n = 5009) from the Scandinavian Quality Register for Thyroid, Parathyroid and Adrenal Surgery between 2003 and 2013 was matched with population controls (n = 14,983). Data were cross-linked with Statistics Sweden and the National Board of Health and Welfare. MEASUREMENTS: Preoperative serum calcium and adenoma weight at pathological examination. RESULTS: Patients had an increased incidence rate of any fracture preoperatively, IRR 1.27 (95% confidence interval: 1.11-1.46), highest in the last year before surgery. Fracture incidence was not increased postoperatively. Serum calcium, adenoma weight and multiglandular disease were not associated with fracture incidence. CONCLUSIONS: Fracture incidence is higher in patients with primary hyperparathyroidism but is normalized after surgery.

RESUMEN

BACKGROUND: It remains unclear the effect of prior endoscopic resection (ER) on the secondary surgery (SS) for T1 colorectal cancer (CRC). This study aimed to compare the short- and long-term outcomes between primary surgery (PS) and ER followed by SS for T1 CRC. METHODS: A systematic literature search was performed in PubMed and Ovid for studies comparing PS with ER followed by SS for T1 colorectal cancer. The last search was performed on 18 May 2021. The primary outcomes were surgical parameters and the secondary outcomes were survival indicators. The meta-analysis was performed with Review Manager Software (version 5.3). RESULTS: A total of fifteen studies published between 2013 and 2021 with 4349 patients were included in this meta-analysis finally. No significant difference was observed between the two groups for operative time (P = 0.75, WMD = 3.16, 95%CI [-15.88, 22.19], I2 = 64%), blood loss (P = 0.86, WMD = 12.33, 95%CI [-122.99, 147.65], I2 = 95%), and postoperative complications (P = 0.59, OR = 0.93, 95%CI [0.71, 1.22], I2 = 0%). Besides, the two groups showed comparable survival outcomes, including overall recurrence rate (P = 0.15, OR = 0.78, 95%CI [0.56, 1.09], I2 = 23%) and 5-year overall survival (P = 0.76, OR = 0.86, 95%CI [0.33, 2.25], I2 = 0%). In the subgroup analysis for studies with propensity matching score or lesions located in the rectum, the results were not changed. CONCLUSION: ER followed by SS is feasible for T1 CRC with high-risk factors. The prior ER would not bring additional adverse effects to the SS. More advanced tools should be developed to improve the diagnostic accuracy for the high-risk factors before treatment for T1 CRC.

RESUMEN

AIMS: The aim of this study was to conduct a cross-sectional, observational cohort study of patients presenting for revision of a total hip, or total or unicompartmental knee arthroplasty, to understand current routes to revision surgery and explore differences in symptoms, healthcare use, reason for revision, and the revision surgery (surgical time, components, length of stay) between patients having regular follow-up and those without. METHODS: Data were collected from participants and medical records for the 12 months prior to revision. Patients with previous revision, metal-on-metal articulations, or hip hemiarthroplasty were excluded. Participants were retrospectively classified as 'Planned' or 'Unplanned' revision. Multilevel regression and propensity score matching were used to compare the two groups. RESULTS: Data were analyzed from 568 patients, recruited in 38 UK secondary care sites between October 2017 and October 2018 (43.5% male; mean (SD) age 71.86 years (9.93); 305 hips, 263 knees). No significant inclusion differences were identified between the two groups. For hip revision, time to revision > ten years (odds ratio (OR) 3.804, 95% confidence interval (CI) (1.353 to 10.694), p = 0.011), periprosthetic fracture (OR 20.309, 95% CI (4.574 to 90.179), p < 0.001), and dislocation (OR 12.953, 95% CI (4.014 to 41.794), p < 0.001), were associated with unplanned revision. For knee, there were no associations with route to revision. Revision after ten years was more likely for those who were younger at primary surgery, regardless of route to revision. No significant differences in cost outcomes, length of surgery time, and access to a health professional in the year prior to revision were found between the two groups. When periprosthetic fractures, dislocations, and infections were excluded, healthcare use was significantly higher in the unplanned revision group. CONCLUSION: Differences between characteristics for patients presenting for planned and unplanned revision are minimal. Although there was greater healthcare use in those having unplanned revision, it appears unlikely that routine orthopaedic review would have detected many of these issues. It may be safe to disinvest in standard follow-up provided there is rapid access to orthopaedic review. Cite this article: Bone Joint J 2022;104-B(1):59-67.

Background: Radiotherapy following primary operation is strongly recommended for salivary gland carcinomas (SGCs) with adverse features. The interval between surgery and the initiation of radiotherapy (SRT) varied and a prolonged SRT may cause failure of cancer treatment. However, the association of SRT with survival is unclear in major SGCs. Methods: This retrospective study included a total of 346 patients who underwent radiotherapy after the primary operation from Fudan University Shanghai Cancer Center from 2005 to 2020. The best cutoff value of the SRT was determined by the maximum log-rank statistic method. The primary endpoint of the study was overall survival (OS). Correlations between variables and OS were conducted by the univariable analysis using the Log-rank method, and a multivariate Cox proportional hazards regression was performed to identify the independent prognostic factors associated with OS. The estimated survival rates were captured using the Kaplan-Meier method. Results: With a median follow-up time of 70.31 months, the estimated 5-year OS, LRFS, and DMFS were 83.3%, 80.1%, and 75.9%, respectively. The cutoff value for SRT was 8.5 weeks, while age, T stage, N stage, perineural invasion (PNI), pathological aggression, chemotherapy, and SRT were associated with OS in the univariable analysis. The Cox regression analysis demonstrated that older age (P < 0.001), T3-4 tumors (P = 0.007), positive N stage (P < 0.001), pathological aggression (P = 0.014), and longer SRT (P = 0.009) were independent prognostic factors for major SGCs. Using the stratification model, we observed that delay in the SRT was associated with worse OS (P = 0.006) in the high-risk group, whereas no significant difference was observed in the low-risk subgroup (P = 0.61). Conclusions: The delay in the initiation of postoperative radiotherapy may be a prognostic factor for patients with major SGCs. It was suggested that radiotherapy should be delivered within 8.5 weeks following the operation, especially for patients with ≥2 risk factors, including older age, high pathological aggression, T3-4 tumors, and positive N stage.

RESUMEN

AIMS: The purpose was to compare operative treatment with a volar plate and nonoperative treatment of displaced distal radius fractures in patients aged 65 years and over in a cost-effectiveness analysis. METHODS: A cost-utility analysis was performed alongside a randomized controlled trial. A total of 50 patients were randomized to each group. We prospectively collected data on resource use during the first year post-fracture, and estimated costs of initial treatment, further operations, physiotherapy, home nursing, and production loss. Health-related quality of life was based on the Euro-QoL five-dimension, five-level (EQ-5D-5L) utility index, and quality-adjusted life-years (QALYs) were calculated. RESULTS: The mean QALYs were 0.05 higher in the operative group during the first 12 months (p = 0.260). The healthcare provider costs were €1,533 higher per patient in the operative group: €3,589 in the operative group and 2,056 in the nonoperative group. With a suggested willingness to pay of €27,500 per QALY there was a 45% chance for operative treatment to be cost-effective. For both groups, the main costs were related to the primary treatment. The primary surgery was the main driver of the difference between the groups. The costs related to loss of production were high in both groups, despite high rates of retirement. Retirement rate was unevenly distributed between the groups and was not included in the analysis. CONCLUSION: Surgical treatment was not cost-effective in patients aged 65 years and older compared to nonoperative treatment of displaced distal radius fractures in a healthcare perspective. Costs related to loss of production might change this in the future if the retirement age increases. Level of evidence: II Cite this article: Bone Jt Open 2021;2(12):1027-1034.
