RESUMEN

INTRODUCTION: Intraoperative specimen radiography is a routinely used procedure to ensure adequate resection of non-palpable breast tumors. Intraoperative digital specimen mammography (IDSM) is an alternative to conventional specimen radiography (CSR) which provides immediate specimen evaluation and can potentially decrease operation time. IDSM may also result in lower positive margin and re-excision rates. IDSM was implemented in our hospital in 2018. The objective of this study was to evaluate the effect of using IDSM versus CSR on operation time, margin status and re-excision rates in breast conserving surgery. METHODS: The present study is a single-center retrospective cohort study with 2 patient cohorts: one which underwent CSR (n = 532) and one which underwent IDSM (n = 475). The primary outcome was the operation time. Secondary outcomes were the margin status of the primary surgery, the cavity shaving rate, and the re-excision rate. Differences between cohorts were compared using univariate statistics and multiple regression analyses to adjust for variables that were significantly different between the groups. RESULTS: IDSM use was associated with an 8-minute reduction in surgery time (B = -8.034, 95% CI [-11.6, -4.5]; P < .001). Treatment variables independently associated with the operation time included use of IDSM, type of surgery, and performance of cavity shaving. Cavity shaves were more often performed when IDSM was used (24% for IDSM vs. 14% for CSR, P < .001), while the proportion of negative margin rates (93% for IDSM vs. 96% for CSR, P = .070) was comparable. CONCLUSION: IDSM was associated with a modest reduction in operation time. Surgeons performed more cavity shaves since the introduction of IDSM, but this increase was not reflected by difference in negative margin rates.

RESUMEN

Background: The radial head fractures comprise approximately 4% of all fractures around the elbow. The outcomes of open reduction and internal fixation are poor in fractures with more than three fragments, and the excision of radial head is considered a viable surgical treatment option. However, it is associated with its own set of complications. The radial head prosthetic replacement has emerged as an alternative in management of these fractures with constraints of cost and related complications. Hence, the treatment for the unrepairable comminuted radial head fractures still remains controversial. Aims and Objectives: This systematic review and meta-analysis was conducted to compare the post-operative outcomes of the radial head excision versus prosthetic replacement in comminuted Mason type-III fractures of radial head. Methodology: Three databases of Medline (PubMed), Scopus, and Embase were searched for comparative studies on the study question and relevant studies which mentioned at least one of the outcomes of interest (functional outcome scores and number of complications) were included. Results: Six studies were part of this review with 82 excisions and 99 prosthetic replacements. There was no significant difference between the two groups in terms of number of complications (OR 0.65; 0.08-5.07); and measures of functional outcomes; Mayo elbow performance score or MEPS (mean difference - 6.56; - 23.45 to 10.33). The incidence of elbow osteoarthritis, heterotrophic ossification, stiffness, and instability were similar in both groups. The flexion extension arc in degrees was better in excision group (mean difference 9.93; 1.31-18.55; p = .02). Conclusion: Excision is a reasonable surgical option for isolated comminuted radial head fractures with similar results of function and associated rates of complications as prosthetic replacements. The arc of motion is also better with excisions. There have been reports of more osteoarthritis with excision and arthroplasty has been advised in younger patients; however, we had no quantitative proof of that in this review.

RESUMEN

Dermatologic surgery has 2main objectives: 1) to guarantee surgical radicality; and 2) to achieve optimal aesthetic and functional results. These 2paradigms and their hierarchy must be considered when performing surgical procedures on the skin. Even the easiest intervention, the elliptical excision, presents some features that should be known to achieve such goals. One of these features is the incision orientation. The optimal incisions orientation is still matter of debate, especially because studies that compare the outcomes of performing incisions in different directions are lacking. However, some anatomical, clinical, and histological observations may point out why incising the skin in one orientation is better than another. Knowing the theory behind skin incisions/excisions become of outmost importance when dealing with primary cutaneous melanoma surgery. Especially if the melanocytic lesion is suspected to be an invasive melanoma and a sentinel lymph node biopsy will be required.

RESUMEN

BACKGROUND: Public health newborn screening (NBS) programs continuously evolve, taking advantage of international shared learning. NBS for severe combined immunodeficiency (SCID) has recently been introduced in many countries. However, comparison of screening outcomes has been hampered by use of disparate terminology and imprecise or variable case definitions for non-SCID conditions with T-cell lymphopenia. OBJECTIVES: This study sought to determine whether standardized screening terminology could overcome a Babylonian confusion and whether improved case definitions would promote international exchange of knowledge. METHODS: A systematic literature review highlighted the diverse terminology in SCID NBS programs internationally. While, as expected, individual screening strategies and tests were tailored to each program, we found uniform terminology to be lacking in definitions of disease targets, sensitivity, and specificity required for comparisons across programs. RESULTS: The study's recommendations reflect current evidence from literature and existing guidelines coupled with opinion of experts in public health screening and immunology. Terminologies were aligned. The distinction between actionable and nonactionable T-cell lymphopenia among non-SCID cases was clarified, the former being infants with T-cell lymphopenia who could benefit from interventions such as protection from infections, antibiotic prophylaxis, and live-attenuated vaccine avoidance. CONCLUSIONS: By bringing together the previously unconnected public health screening community and clinical immunology community, these SCID NBS deliberations bridged the gaps in language and perspective between these disciplines. This study proposes that international specialists in each disorder for which NBS is performed join forces to hone their definitions and recommend uniform registration of outcomes of NBS. Standardization of terminology will promote international exchange of knowledge and optimize each phase of NBS and follow-up care, advancing health outcomes for children worldwide.

RESUMEN

Objective: This meta-analysis was performed to evaluate the effectiveness and safety of prophylactic central neck dissection (PCND) in patients with clinically node-negative (cN0) papillary thyroid carcinoma. Materials and methods: A meta-analysis of the literature was performed using the key words "papillary thyroid carcinomas" and "lymph node ecisions" for searches of electronic databases. Complications such as transient hypocalcemia, permanent hypocalcemia, transient and permanent hypoparathyroidism, transient and permanent vocal cord paralysis, transient recurrent and permanent recurrent laryngeal nerve injury, and local recurrence were pooled by meta-analysis. Stata17.0 was used to carry out the meta-analysis. Results: Data were extracted from 15 studies. In the present review, the group of patients who had total thyroidectomy (TT) with PCND had a lower local recurrence than the group with TT alone (OR 0.22, 95% CI 0.10-0.45, P = 0.000), whereas the incidence of permanent hypocalcemia (OR 4.24, 95% CI 1.05-17.22, P = 0.043) and transient hypoparathyroidism (OR 2.14, 95% CI 1.34-3.42, P =0.001) were higher. No significant differences were recorded in the incidence of other complications: transient hypocalcemia (OR 2.24, 95% CI 0.77-6.51, P = 0.138), permanent hypoparathyroidism (OR 1.70, 95% CI 0.89-3.27, P = 0.111), transient vocal cord paralysis (OR 1.48, 95% CI 0.78-2.83, P = 0.231), permanent vocal cord paralysis (OR 1.44, 95% CI 0.53-3.94, P = 0.477), transient recurrent laryngeal nerve injury (OR 1.47, 95% CI 0.93-2.32, P = 0.102) and permanent recurrent laryngeal nerve injury (OR 1.24, 95% CI 0.56-2.74, P = 0.587) between the two groups. Conclusion: Compared with TT alone, TT with PCND was more effective in reducing local recurrence without increasing the risk of recurrent laryngeal nerve, thyroid and vocal cord, except for hypocalcemia and transient hypoparathyroidism. Therefore, we believe that TT with PCND should be recommended for patients with cN0 PTC. Systematic review registration: https://www.crd.york.ac.uk/prospero/, identifier CRD4202 2355078.

RESUMEN

AIMS: Patients with soft-tissue sarcoma (STS) who undergo unplanned excision (UE) are reported to have worse outcomes than those who undergo planned excision (PE). However, others have reported that patients who undergo UE may have similar or improved outcomes. These discrepancies are likely to be due to differences in characteristics between the two groups of patients. The aim of the study is to compare patients who underwent UE and PE using propensity score matching, by analyzing data from the Japanese Bone and Soft Tissue Tumor (BSTT) registry. METHODS: Data from 2006 to 2016 was obtained from the BSTT registry. Only patients with STS of the limb were included in the study. Patients with distant metastasis at the initial presentation and patients with dermatofibrosarcoma protuberans and well-differentiated liposarcoma were excluded from the study. RESULTS: A total of 4,483 patients with STS of the limb were identified before propensity score matching. There were 355 patients who underwent UE and 4,128 patients who underwent PE. The five-year disease-specific survival (DSS) rate was significantly better in the patients who received additional excision after UE than in those who underwent PE. There was no significant difference in local recurrence-free survival (LRFS) between the two groups. After propensity score matching, a new cohort of 355 patients was created for both PE and UE groups, in which baseline covariates were appropriately balanced. Reconstruction after tumour excision was frequently performed in patients who underwent additional excision after UE. There were no significant differences in DSS and LRFS between the patients who underwent PE and those who had an additional excision after UE. CONCLUSION: Using propensity score matching, patients with STS of the limb who underwent additional excision after UE did not experience higher mortality and local failure than those who underwent PE. Reconstruction may be necessary when additional excision is performed. Cite this article: Bone Joint J 2021;103-B(12):1809-1814.

RESUMEN

In Soft Tissue Sarcomas (STS) referral centre many patients have already had an incomplete tumour resection. In the majority of specimen, tumoral residual is detected and linked to a worsen prognosis. Systematic surgical re-resection of the scar tissue area is often performed. Some authors suggested to postpone re-resections until a clinically evident local recurrence is detected. A searching strategy was applied to Pubmed-Central and Ovid Medline. Odds ratio (OR) for local recurrence (LR), distant metastasis (MTS) or overall survival (OS) were calculated comparing patients who had tumour residual to people who hadn't. OR of local recurrences, distant metastasis and OS were calculated in planned vs unplanned-excisions groups. OR to develop a metastasis and OS after a local recurrences were calculated. Residual tumour led to an OR for LR of 3,56, OR of MTS was 3,42; OR of decreased OS was 3,42. Having a LR lead to a OR of 1,55 for MTS and to a OR of decreased OS of 2,32. Patients who underwent a re-excision compared to planned surgery did not have an increased OR of LR and had an OR to develop a MTS of 0,56. Our data confirm that there is a strong correlation between local recurrences, distant relapses and overall survival. Although there is a selection bias; this analysis highlights the optimal oncological outcome in patients who underwent re-resection. The rationale for systematic re-resection after unplanned excision of soft tissue sarcomas is very strong and this treatment remains the gold standard of care in these patients.

RESUMEN

BACKGROUND: This study aimed to investigate the effect of double-lumen irrigation-suction tube (DLIST) in the management of surgical site infections (SSIs) after enterocutaneous fistula (ECF) excisions. METHOD: From January 2016 to December 2017 medical records of patients with ECF excisions were reviewed. Patients with primary superficial SSI were divided into group a (treated with DLIST) and b (treated with delayed primary closures). Patients with primary deep SSI were divided into group A (treated with DLIST) and B (treated with vacuum-assisted closure [VAC]). The effect of the DLIST was evaluated. RESULTS: There were 32 in group a and 27 in group b. The therapeutic time and cost in group a were lower (13.13 ± 2.37 d vs. 24.89 ± 7.44 d; p < .001; $1456 ± 302 vs.$2784 ± 583; p < .001). There were 21 in group A and 23 in group B. While the therapeutic time of group A was longer, the cost was lower ($1717 ± 404 vs. $2636 ± 592; p < .001). CONCLUSIONS: Placing DLIST is an effective and cheap method to treat superficial SSI after ECF excisions. The cost of DLIST in treatment of deep SSI is lower, while the effect of VAC is better.

RESUMEN

BACKGROUND: Lymph node (LN) harvest in colorectal cancer resections is a well-recognised prognostic factor for disease staging and determining survival, particularly for node-negative (N0) diseases. Extralevator abdominoperineal excisions (ELAPE) aim to prevent "waisting" that occurs during conventional abdominoperineal resections (APR) for low rectal cancers, and reducing circumferential resection margin (CRM) infiltration rate. Our study investigates whether ELAPE may also improve the quality of LN harvests, addressing gaps in the literature. METHODS: This retrospective observational study reviewed 2 sets of 30 consecutive APRs before and after the adoption of ELAPE in our unit. The primary outcomes are the total LN counts and rates of meeting the standard of 12-minimum, particularly for those with node-negative disease. The secondary outcomes are the CRM involvement rates. Baseline characteristics including age, sex, laparoscopic or open surgery and the use of neoadjuvant chemoradiotherapy were accounted for in our analyses. RESULTS: Median LN counts were slightly higher in the ELAPE group (16.5 vs. 15). Specimens failing the minimum 12-LN requirements were almost significantly fewer in the ELAPE group (OR 0.456, P = 0.085). Among node-negative rectal cancers, significantly fewer resections failed the 12-LN standard in the ELAPE group than APR group (OR 0.211, P = 0.044). ELAPE led to a near-significant decrease in CRM involvement (OR 0.365, P = 0.088). These improvements were persistently observed after taking into account baselines and potential confounders in regression analyses. CONCLUSION: ELAPE provides higher quality of LN harvests that meet the 12-minimal requirements than conventional APR, particularly in node-negative rectal cancers. The superiority is independent of potential confounding factors, and may implicate better clinical outcomes.

RESUMEN

BACKGROUND: Unplanned excisions of soft tissue sarcomas are still not infrequent events with patients presenting to referral Centers after having received an inadequate surgical treatment. In literature, both the wait-and-see policy and the "aggressive" management with a re-excision have been advocated. The purposes of this study were to analyze the incidence of detectable residual tumor in surgical specimens following a re-excision and to verify the long-term results of patients treated with a re-excision after previous unplanned excision. METHODS: We retrospectively evaluated 131 patients affected by localized soft tissue sarcoma (95 high grade; 36 low grade) of the limbs or the superficial trunk treated at our Institution, from 2000 to 2013, with a re-excision after a previous unplanned inadequate excision. Site, size, depth, histotype, grade, adjuvant therapies, time from unplanned surgery to re-excision were recorded and evaluated in association with clinical results. We specifically evaluated the disease-specific survival, local recurrence free survival, distant metastases free survival and the event free survival. RESULTS: Mean follow-up for living patients was 10.9 years (median 11.2 years), with a follow-up ranging from 14 to 227 months. 34% of patients underwent a re-excision within the first 2 months after unplanned surgery, while 66% of patients at more than 2 months. Residual detectable tumor cells were found on histological examination in 54% of re-excisions. A wide margin was obtained in 123 cases, a persisting positive margin in 8 patients. Disease-specific survival was 93.5%, 91.6% and 89.6% at 5, 10 and 15 years for whole series and 90.9%, 88.2% and 85.7% for high grade tumors. Event-free survival in patients affected by high grade tumors rated 75.0% at 5 years, 72.4% at 10 years and 72.4% at 15 years. Local recurrence free survival in high grade tumors was 87.6%, 86.2% and 86.2% at 5, 10 and 15 years. The grade of the tumor (high grade) and the initial dimension of the tumor (≥5 cm) were associated with worst survival. High grade tumor impacted negatively also on local recurrence free survival and event free survival. Instead, the initial size of the tumor significantly affected the event free survival but not the local recurrence free survival. No significant differences of outcome were found analyzing tumor depth, time interval to re-excision, presence of residual tumor or margins. CONCLUSION: Based on our results and literature findings, we believe that surgeons should offer a re-excision procedure in those patients presenting with an inadequate excision of a high grade soft-tissue tumor, in particular with tumors larger than 5 cm before excision. Indeed, if an adequate second treatment is performed with surgery ± radiotherapy, the long-term results of patients receiving a re-excision after unplanned excision of a high grade soft tissue sarcoma seem to be comparable to the results generally reported for wide primary excisions. More debatable is whether to perform a re-excision or not in patients with low-grade tumors. Perhaps, in this latter group a wait and see policy can eventually be offered as well as in high grade tumors when a re-excision procedure could involve major surgery or significantly affect postoperative function.

RESUMEN

BACKGROUND/AIM: Surgical margin status remains an important determinant for recurrence of invasive breast cancer and ductal carcinoma in situ. We compared the number of positive margins in initial histology with rates of residual tumor in re-excision specimens. Furthermore, we analysed cost-effectiveness of re-excisions. PATIENTS AND METHODS: 101 patients treated with secondary surgery were included. The first group underwent breast conserving surgery and secondary mastectomy. The second group was primarily treated with subcutaneous mastectomy followed by secondary surgery. RESULTS: Within the first group, 22.7% did not show residual tumor in the re-excision specimen. Of the second group, 54.3% had no residual tumor. Consequentially 45.7% needed a re-excision to achieve R0 status. Cost-effectiveness was determined as secondary endpoint. If a patient needs a secondary mastectomy the hospital gains 602,65€ in comparison to a primary breast conserving operation. CONCLUSION: In every second patient who had first received a subcutaneous mastectomy, no tumor could be detected in the secondary operation despite a previous R1 status.

RESUMEN

BACKGROUND: Acne inversa as a chronic inflammatory disorder can be divided into three stages according to Hurley's classification. It affects the axillary and anogenital region predominantly, and its chronic course of development is associated with a major negative impact on quality of life, especially in young patients. We discuss the different types of treatment in patients with acne inversa and the benefits of two-stage surgical treatment by serial excisions with primary wound closure under local anaesthesia. CASE REPORT: We present a 28-year-old man with hidradenitis suppurativa stage I in the right axillary region and also in the pubic area. The patient is an active smoker. The patient was treated with Rifampicin 2x 300mg / day without any particular effect and preoperatively, systemic therapy with Clindamycin 4x 600mg / day was performed, combined with daily dressings with jodasept ointment for 7 days. The patient was treated through two surgical sessions under local anaesthesia with elliptical excision of the lesions located in the right axillary and the pubic area. Both of the two surgical defects were initially closed with single interrupted sutures. Histological examination of both lesions revealed the presence of suppurative folliculitis. CONCLUSION: The literature describes various methods for treating acne inversa which include both systemic and local approaches. However, it is considered that drug therapy achieves only a temporary improvement in patients with hidradenitis suppurativa. For this reason, the surgical treatment of acne inversa is indicated as the only curative treatment, especially for recurrent lesions and serial excisions under local anaesthesia, followed by primary wound closure is a valuable treatment for patients with mild to moderate HS (Hurly stage I & II).

RESUMEN

PURPOSE: The purpose of this study was the evaluation of risk factors for local recurrence after breast conserving surgery (BCS) with special focus on the impact of residual disease in specimens of simultaneous additional excisions (AE) from the tumor cavity on patients' outcome in patients with negative final margin status after one-step BCS. METHODS: This study was designed as a single center retrospective cohort study. Patients with primary non-metastatic breast cancer treated by one-step BCS with pathologically confirmed negative resection status between 1990 and 2006 were included. Ipsilateral breast tumor recurrence (IBTR) and overall survival (OS) were evaluated by Kaplan-Meier-estimates. A multivariate Cox proportional hazards regression model was used to identify potential independent prognostic factors associated with the risk of IBTR. RESULTS: A total of 1081 patients were included in this analysis. Simultaneous additional excisions were performed in 79.4% of patients (tumor positive: 12.2%). Median follow-up after primary diagnosis was 124 months. The IBTR rate after 15 years was significantly higher in the group with tumor positive AE (no AE (10.2%) vs. AE tumor positive (27.5%) p = 0.002; AE tumor negative (14.0%) vs. AE tumor positive (27.5%) p = 0.008). The OS rate did not differ significantly between groups. Multivariate analysis revealed residual cancer in AE being associated with a significantly increased relative risk of IBTR of 2.0 (p = 0.014). CONCLUSION: In the current analysis residual disease in simultaneous additional excisions was associated with an increased risk for IBTR despite negative final margin status. This should be considered in the overall therapeutic concept.

RESUMEN

Little is known about the spectrum of pediatric skin disorders requiring biopsy/excision, their indication, impact on further management, and the accuracy of clinical diagnosis. We aimed to address these questions in the patient population seen at our Swiss University referral center for Pediatric Dermatology and Plastic Surgery. All skin biopsies/excisions performed in patients aged ≤ 16 years over a period of 2 years were retrospectively analyzed. A total of 506 samples were included. The majority of biopsies/excisions (n = 413, 82%) was performed for tumors, cysts, and hamartomas and 18% for other skin conditions. Malignant tumors were found in 12 samples (2%) from four patients. In 121 (24%) patients, the histopathology had an important impact on patient management. In 80 (16%) cases, the pathology did not match with the clinical diagnosis. In 382 (75%) cases, excision was the treatment of choice. Of these, the indication for surgery was based on patient's request in 181 (47%) cases. CONCLUSION: Surgical interventions for pediatric skin disorders are performed for diagnostic and therapeutic reasons. In this cohort, histopathology was essential for treatment in one quarter of cases. Skin tumors, cysts, and hamartomas often require excision during childhood, with families' request and esthetic considerations playing an important role. What is Known: • The spectrum of pediatric skin conditions has been studied in outpatient, inpatient, and emergency settings. • In contrast, no data exist on the spectrum of pediatric skin disorders undergoing biopsy/excision specifically. What is New: • We analyze biopsies/excisions in children, focusing on diagnosis, indication, and impact on patient management. • Surgical interventions for skin disorders in children are often performed for tumors and hamartomas with esthetic considerations playing a relevant role. If used for diagnostic purposes, they are often performed to confirm or rule out severe skin disease.
