RESUMEN

Bilateral femoral hernia is extremely rare in children. The diagnosis is challenging, and it often requires multiple surgeries before the correct treatment can be provided. In this case report, a five-year-old boy had two surgeries on suspicion of a right-sided inguinal hernia, but no hernia was found. After the second operation, the suspicion of a hernia was still present. This led to a diagnostic laparoscopy, where a bilateral femoral hernia was found. Laparoscopic McVay procedure was performed on both sides with minor modifications, which consisted of hernia sac plication and fixation to fortify the abdominal wall.

RESUMEN

Inguinal bladder hernia is a rare clinical condition, and only a small number of reported cases have been treated by laparoscopic surgery. We report a case of a patient aged 65-year-old who presented to our outpatient care unit for a right inguinal swelling. Computer tomography (CT) imaging showed a direct inguinal hernia with bladder and epiploic content. We performed a laparoscopic transabdominal preperitoneal repair, which involved carefully reducing the bladder's protrusion from the hernial orifice. Subsequently, a mesh prosthesis was employed to treat the right inguinal hernia. This case represents an unusual instance of a successful laparoscopic repair for a right direct inguinal bladder hernia.

RESUMEN

INTRODUCTION: There are some complications that can arise after surgery, like surgical site infection (SSI). In hernia repair, SSI incidence is low. Hence, the clinical practice guideline (CPG) published by the HerniaSurge Group (THG) does not recommend prophylactic antibiotics for hernia repair. Despite the unnecessary use of prophylactic antibiotics, regarding patient safety, prophylactic antibiotics can be used. However, each hospital has its own CPG and recommended antimicrobials based on the infection cases in its site. Regarding antimicrobial resistances, evaluating prophylactic antibiotics is essential to prevent increasing incidence of antimicrobial resistance cases. The aim of this study is to evaluate the use of prophylactic antibiotics in hernia inguinal cases. MATERIALS AND METHODS: This cross-sectional analytic study used patients' medical records between 2015 to 2020. Demographic data, surgery data and the used antimicrobial data were extracted and written in case report form. Identification of risk factors for inappropriate use of prophylactic antibiotics was done using logistic regression. RESULTS: We identified 55 inappropriate times of preoperative prophylactic antibiotic therapy cases out of 80 cases and 63 cases in post-operative antibiotics were different from the guideline. Statistical analysis did not find any factor related to inappropriate therapy time. CONCLUSION: The misuse of prophylactic antibiotics was frequently found regarding the duration of prophylactic antibiotics in both pre- and post-surgery setting. Nonetheless, no risk factor was identified with the inappropriate use of prophylactic antibiotics.

RESUMEN

OBJECTIVE: Exploration of the efficacy of treating large indirect inguinal hernias in infants and young children using umbilical double-port laparoscopy combined with extraperitoneal water injection. METHODS: A retrospective analysis was conducted on 165 cases of primary unilateral large indirect inguinal hernias in infants and young children treated at our hospital from May 2018 to May 2023. Among them, 90 cases underwent umbilical double-port laparoscopic surgery combined with extraperitoneal water injection and high ligation of the hernia sac (Double-Port Group), and another 75 cases underwent conventional three-port laparoscopic high ligation of the hernia sac (Three-Port Group). The two groups were compared in terms of operation time, postoperative pain scores at 24 hours, hospital stay, incision complications, and recurrence within one year after surgery. RESULTS: Both groups successfully completed the surgery without any intraoperative complications. The pain score at 24 hours postoperatively was lower in the Double-Port Group compared to the Three-Port Group, and there was no statistically significant difference in operation time, hospital stay, and incision complications between the two groups (P > 0.05). Both groups were followed up for one year postoperatively; the Three-Port Group had one recurrence that was cured after further treatment, while there were no recurrences in the Double-Port Group. CONCLUSION: Umbilical double-port laparoscopy combined with extraperitoneal water injection for the treatment of large indirect inguinal hernias in infants and young children has the advantages of being safe and reliable, with concealed and aesthetic incisions, and rapid recovery.

RESUMEN

BACKGROUND: Benign prostatic hyperplasia (BPH) is a prevalent condition in aging males, leading to bladder outlet obstruction (BOO) and associated urinary symptoms. With increasing life expectancy, the incidence of BPH and its co-morbidities, like inguinal hernia, has risen. This study explores the efficacy of combining transurethral resection of the prostate (TURP) and inguinal hernioplasty in a single surgical session to address both conditions, potentially reducing the need for multiple hospitalizations and surgical interventions. METHODS: This retrospective study at Chi Mei Medical Center included patients from 2014 to 2023 who underwent concurrent TURP and inguinal hernioplasty. A total of 85 patients met the criteria defined for this study. Preoperative, intraoperative, and postoperative characteristics were meticulously documented. Outcomes evaluated included the duration of the surgery, incidence of intraoperative and postoperative complications, duration of Foley catheterization, length of hospital stay, and treatment efficacy. Additionally, we conducted a comparative assessment of the surgical outcomes between two distinct techniques for inguinal hernia repair: open hernioplasty and laparoscopic hernioplasty (LH). RESULTS: In 85 patients who met the criteria, the mean age was 71.1 ± 7.8 years. The study reported no significant intraoperative complications, and postoperative care was focused on monitoring for blood loss, infection, and managing pain. The average postoperative hospital stay was 2.9 ± 1.0 days and the mean duration of catheterization was 51.6 ± 16.7 h, with a minimal complication rate observed during the one-year follow-up. A significant reduction in both operative duration and catheterization interval was observed in patients undergoing LH as opposed to those receiving open hernioplasty. CONCLUSION: Concurrent TURP and inguinal hernioplasty effectively manage BOO due to BPH and inguinal hernias with minimal complications, suggesting a viable approach to reducing hospital stays and surgical interventions. Laparoscopic techniques, in particular, offer benefits in operative efficiency and recovery time, making combined surgery a feasible option for selected patients.

RESUMEN

BACKGROUND: Testicular ischemia requires timely diagnosis and definitive management to avoid serious consequences such as orchiectomy. It is almost always caused by testicular torsion; however, there are other causes to be aware of. CASE REPORT: A 32-year-old man developed testicular ischemia following a laparoscopic robotic-assisted inguinal hernia repair with preperitoneal mesh. The ischemia progressed to a fully infarcted testicle with no evidence of torsion on subsequent surgical exploration. He ultimately did require an orchiectomy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: While extremely rare, testicular ischemia or infarct must be considered in patients presenting with testicular pain shortly after inguinal hernia repair. Emergent surgical evaluation and loosening of the hernia mesh may be required to salvage the testicle.

RESUMEN

OBJECTIVE: Barros et al. demonstrated a 3D printed model that exhibits anatomical representativeness, low cost, and scalability. The model was created based on subtraction data obtained from computed tomography scans. Images were modeled and reconstructed in 3D to display the male inguinal region, typically viewed using a laparoscopic approach. To evaluate the functionality and quality of the anatomical representation of the hernia 3D training model. METHODS: A model was created based on subtraction data derived from computed tomography scans of the pelvic bones and lumbar spine using the Blender 3.2.2 software program. Images were modeled and reconstructed in 3D to display the male inguinal region, typically viewed using a laparoscopic approach. Polylactic acid plastic was used to print the model. Some structures were made using ethylene vinyl acetate to enable possible material replacement and model reutilization. Thirty surgeons with various training levels were invited to use the model. Transabdominal inguinal hernioplasty was performed by simulating the same steps as those of a laparoscopic surgery, and the surgeons answered a questionnaire regarding the simulation. RESULTS: Twenty-eight surgeons responded, seven of whom were experts in the treatment of abdominal wall hernias. The model was deemed easy to use, realistic, and anatomically precise, establishing it as a valuable supplement to minimally invasive surgery training. CONCLUSION: The evaluation of this 3D model was favorable, as it accurately depicted the inguinal region anatomically, while also proving to be cost-effective for training purposes. The model could be a good option, particularly beneficial for training surgeons at the beginning of their careers.

RESUMEN

BACKGROUND: Inguinal hernia repair is a frequently performed surgical procedure, with laparoscopic repair emerging as the preferred approach due to its lower complication rate and faster recovery compared to open repair. Mesh-based tension-free repair is the gold standard for both methods. In recent years, robotic hernia repair has been introduced as an alternative to laparoscopic repair, offering advantages such as decreased postoperative pain and improved ergonomics. This study aims to compare the short- and long-term outcomes, including the surgical stress response, postoperative complications, quality of life, and sexual function, between robotic-assisted transabdominal preperitoneal (rTAPP) and laparoscopic TAPP inguinal hernia repairs. METHODS: This randomized controlled trial will involve 150 patients from the Surgical Department of the University Hospital of Southern Denmark, randomized to undergo either rTAPP or laparoscopic TAPP. Surgical stress will be quantified by measuring C-reactive protein (CRP) and cytokine levels. Secondary outcomes include complication rates, quality of life, sexual function, and operative times. Data analysis will adhere to the intention-to-treat principle and will be conducted once all patient data are collected, with outcomes assessed at various postoperative intervals. DISCUSSION: This study holds significance in evaluating the potential advantages of robotic-assisted surgery in the context of inguinal hernia repairs. It is hypothesized that rTAPP will result in a lower surgical stress response and potentially lower the risk of postoperative complications compared to conventional laparoscopic TAPP. The implications of this research could influence future surgical practices and guidelines, with a focus on patient recovery and healthcare costs. The findings of this study will contribute to the ongoing discourse surrounding the utilization of robotic systems in surgery, potentially advocating for their broader implementation if the benefits are substantiated. TRIAL REGISTRATION: ClinicalTrials.gov NCT05839587. Retrospectively registered on 28 February 2023.

RESUMEN

OBJECTIVE: To assess the effectiveness of a modified Lichtenstein Repair combined with Herniorrhaphy in reducing postoperative chronic pain and enhancing recovery and quality of life in inguinal hernia patients. METHODS: This retrospective study, conducted at the Taleghani training center between January 2021 and February 2023, retrospectively examined 289 hernia surgeries, of which 130 employed a modified Lichtenstein technique. The investigation encompassed a detailed analysis of patient demographics, employed surgical techniques, operative methods with a focus on minimal dissection, and an evaluation of postoperative outcomes. RESULTS: In this study of 289 participants, primarily males aged 60-80 years, the modified technique group demonstrated a notably lower incidence of hernia recurrence (1.5%) compared to the Lichtenstein group (3.1%). Additionally, the modified technique was more effective in reducing postoperative pain, with a significantly lower mean Visual Analogue Scale (VAS) score of 0.15, compared to 0.31 in the Lichtenstein group. This suggests enhanced patient comfort and a potentially quicker recovery in the modified technique group. CONCLUSION: The modified Lichtenstein hernioplasty technique, characterized by minimal tissue trauma and precise mesh placement, emerges as an effective approach in inguinal hernia repair. It offers significant benefits in reducing postoperative discomfort and chronic pain, thereby enhancing patient recovery and overall quality of life. This method aligns with current surgical trends towards patient-centric and minimally invasive procedures.

RESUMEN

INTRODUCTION: There is uncertainty regarding the method of mesh fixation and peritoneal closure during transabdominal preperitoneal (TAPP) repair for inguinal hernias, with no definitive guidelines to guide surgeon choice. METHODS: MEDLINE, Cochrane, Central Register of Clinical Trials, and Web of Science were searched for RCTs published until November 2023. Risk ratios (RRs) and mean differences (MD) with 95% confidence intervals (CIs) were pooled with a random-effects model. Statistical significance was defined as p < 0.05. Heterogeneity was assessed using the Cochran Q test and I2 statistics, with p values inferior to 0.10 and I2 > 25% considered significant. Statistical analyses were conducted using Review Manager version 5.4 and RStudio version 4.1.2 (R Foundation for Statistical Computing). RESULTS: Eight randomized controlled trials (RCTs) were included, comprising 624 patients, of whom 309 (49.5%) patients were submitted to TAPP with the use of tacks, and 315 (50.5%) received suture fixation. The use of tacker fixation was associated with a significant increase in postoperative pain at 24 h (MD 0.79 [VAS score]; 95% CI 0.38 to 1.19; p < 0.0002; I2 = 87%) and one week (MD 0.42 [VAS score]; 95% CI 0.05 to 0.79; p < 0.03, I2 = 84%). The use of tacks was associated with shorter operative time (MD-25.80 [min]; 95% - 34.31- - 17.28; P < 0.00001; I2 = 94%). No significant differences were found in overall complications, chronic pain, seromas, hematomas, and urinary retention rates. CONCLUSION: In patients who underwent TAPP hernia repair, tacks are associated with decreased operative time but increased postoperative pain at 24 h and one week.

RESUMEN

BACKGROUND: The repair of inguinal hernias is a common surgical procedure. Some patients will need a second operation after developing a metachronous contralateral inguinal hernia (MCIH). The suggestion has been made to strengthen the contralateral side at the same time as primary unilateral surgery. In this systematic review we aim to determine how many adult patients with a unilateral inguinal hernia will develop a MCIH. METHODS: This review was reported in line with PRISMA guidelines. We performed a literature review in PubMed Publisher, Embase, Google Scholar and Cochrane Library until May 2021, including articles reporting MCIH after unilateral inguinal hernia repair in adults. As outcome measure, the number of patients diagnosed with a MCIH was registered. RESULTS: A total of 19 articles with a total of 277,288 patients were included. The combined estimate for MCIH after meta-analysis equaled 8.3% (95% CI 7.1%-9.5%), with a high index of heterogeneity (I2 = 97.9%). A random-effects meta-regression was performed to obtain the percentage of MCIH as a function of median follow-up time. The percentage of MCIH at 3, 5 and 10 years was estimated at 5.2%, 8.0% and 17.1%, respectively. CONCLUSION: We suggest that there is insufficient clinical evidence to support prophylactic contralateral repair in all patients. We propose a patient-specific approach in the decision to perform prophylactic repair, taking into account potential risk factors for hernia development, type of surgical approach, and general risk factors for chronic postoperative inguinal pain. More long-term prospective data are needed to guide the decision for prophylactic contralateral mesh placement.

RESUMEN

Purpose: Anxiety and depression can affect the physiology of the gastrointestinal tract through the brain-gut axis, causing gastrointestinal dysfunction, which is mainly manifested as indigestion, diarrhoea, constipation, or abdominal pain. Preoperative anxiety arises in children due to separation from parents, fear of unfamiliar surroundings and anaesthesia and surgical procedures.To discuss the effect of alleviating preoperative anxiety on postoperative recovery of gastrointestinal function in children with indirect inguinal hernia after laparoscopic high ligation of the hernia sac. Patients and Methods: 90 children with laparoscopic high ligation of the herniated sac in oblique inguinal hernia were randomly divided into control group (Group C) and experimental group (Group M). The Group M was given midazolam oral solution 0.5mg/kg (maximum dose 20mg), and The Group C was given 5% glucose solution with the same dose.Primary outcome was the time to first postoperative defecation and I-FEED scores.The secondary outcomes included mYPAS-SF scores; child sedation scores; child-parent separation scores; parental STAI scores;PHBQ scores;FLACC scores, operative time, and fluid input and surgeon job satisfaction. Results: Compared with Group C, there was a shorter time to first postoperative defecation (P < 0.05), and lower I-FEED scores on postoperative day 1 (P < 0.05). The mYPAS-SF scores, which were significantly different in Group M at T1, T2, and T3 (P < 0.05), parental STAI scores at S1, child sedation scores and child-parent separation scores in T1, and surgeon job satisfaction between the two groups were significantly different (P < 0.05). There were no statistically significant differences in I-FEED scores on days 2 and 3, PHBQ scores, FLACC scores, operative time, and fluid input between the two groups of children (P > 0.05). Conclusion: Preoperative application of midazolam oral solution to relieve preoperative anxiety helps to promote the recovery of postoperative gastrointestinal function in children with indirect inguinal hernia and increases the surgeon job satisfaction.

RESUMEN

Inguinal hernias are commonly encountered and are primarily managed by surgeons; however, it is unusual for retroperitoneal structures, such as the ureter, to herniate into it. More importantly, hernias containing ureters are not usually identified preoperatively unless specific imaging was ordered prior, as they are generally asymptomatic. This poses a risk to the patient as unidentified structures can be mistakenly injured during the surgery. We describe a case of a man in his 60s, who presented with a large left-sided indirect inguinoscrotal hernia. Intraoperatively, a large amount of irreducible retroperitoneal fat was encountered in addition to a cord-like structure, which was discovered to be the left ureter after reviewing imaging intraoperatively. Initially, the hernia repair was done robotically, but it was converted to open repair due to its irreducibility and the potential risk imposed on the ureter. Additionally, we discuss the aetiology and common presentations of this kind of hernia.

RESUMEN

SummaryCentralized referral systems have been successfully implemented to shorten and equalize surgical wait times; however, ongoing expenses make sustaining these projects challenging. We trialed a low-cost centralized booking project for hernia surgery in a community hospital from July to November 2019. Eligible patients (i.e., those with visible or palpable inguinal or umbilical hernias who were agreeable to an open mesh repair) were booked with the first available surgeon after initial consultation. Centrally booked patients with either inguinal or umbilical hernias waited a mean of 82 (standard deviation [SD] 32) and 80 (SD 66) days, respectively, while those who did not use the centralized system waited 137 (SD 89) and 181 (SD 92) days, respectively. Centralized booking increased operating room utilization as a larger pool of patients was available to call when last-minute cancellation occurred; centralized booking also effectively equalized wait-lists among 6 surgeons. Selective centralized booking is a promising concept that led to more efficient utilization of available operating room time with a significant decrease in wait times; this system could potentially improve access for all patients awaiting general surgery without requiring additional funding.

RESUMEN

PURPOSE: Inguinal hernias are highly prevalent worldwide and its surgical repair is one of the most common procedures in general surgery. The broad use of mesh has decreased the recurrence rates of inguinal hernia to acceptable levels, thus centering the attention on Quality of Life as a pivotal postoperative outcome. Carolinas Comfort Scale is a well-studied questionnaire designed to identify Quality of Life changes following hernia repair with mesh techniques. The aim of this study is to validate the CCS in Brazilian Portuguese for inguinal hernias. METHODS: The original CCS was translated into Brazilian Portuguese according to cross-cultural adaptation guidelines. We conducted a cross-sectional study in individuals aged 18 and above who had undergone inguinal laparo-endoscopic hernia repair for at least 6 months prior, between January 2019 and August 2022, at a Brazilian tertiary hospital. Participants answered an online survey containing the Brazilian CCS and the generic Patient-Reported Outcome Measure (PROM) Short-Form Health 36 (SF-36). Participants answered the same questionnaires in the follow-up after at least three weeks, with an additional question about satisfaction with surgery results. RESULTS: The survey was completed by 115 patients, of whom 78 (67%) responded to the follow-up questionnaire after 3 to 10 weeks. CCS showed excellent internal consistency, with Cronbach's α of 0.94. Intraclass correlation coefficient ranged from 0.60 to 0.82 in the test-retest analysis. Compared to SF-36, a strong correlation was observed in the physical functioning dimension, and a moderate correlation was found in role-physical and bodily pain (Pearson's Coefficient Correlation = 0.502, 0.338 and 0.332 respectively), for construct analysis. The mean CCS score was significantly lower (p < 0.001) among satisfied patients compared to the unsatisfied ones. CONCLUSION: The Brazilian version of CCS is a valid and reliable method to assess long-term quality of life after inguinal laparo-endoscopic hernia repair.

RESUMEN

OBJECTIVE: To evaluate the quality of recommendations provided by ChatGPT regarding inguinal hernia repair. MATERIAL AND METHODS: ChatGPT was asked 5 questions about surgical management of inguinal hernias. The chat-bot was assigned the role of expert in herniology and requested to search only specialized medical databases and provide information about references and evidence. Herniology experts and surgeons (non-experts) rated the quality of recommendations generated by ChatGPT using 4-point scale (from 0 to 3 points). Statistical correlations were explored between participants' ratings and their stance regarding artificial intelligence. RESULTS: Experts scored the quality of ChatGPT responses lower than non-experts (2 (1-2) vs. 2 (2-3), p<0.001). The chat-bot failed to provide valid references and actual evidence, as well as falsified half of references. Respondents were optimistic about the future of neural networks for clinical decision-making support. Most of them were against restricting their use in healthcare. CONCLUSION: We would not recommend non-specialized large language models as a single or primary source of information for clinical decision making or virtual searching assistant.

RESUMEN

To develop a nomogram model for predicting contralateral patent processus vaginalis in children with unilateral inguinal hernia or hydrocele. A retrospective analysis was conducted on 259 children with unilateral inguinal hernia or hydrocele who underwent laparoscopic surgery at the Southern Hospital of Southern Medical University from January 2021 to December 2023. The patients were randomly divided into a training set (n = 207) and a validation set (n = 52) in an 8:2 ratio to analyze the characteristics of CPPV. Multivariate logistic regression analysis was used to screen for independent risk factors for CPPV, and a nomogram prediction model was constructed. The predictive ability, calibration, and clinical net benefit of the model were evaluated by plotting receiver operating characteristic (ROC) curves, calibration curves (HL), and clinical decision curves (DCA). Among children under 1 year old, the laparoscopic exploration revealed a CPPV incidence rate of 55.17%. The incidence rates for children aged 2-10 years ranged from 29.03 to 39.13%, and the incidence rate for children aged 11-14 years was 21.21%. Multivariate logistic regression analysis showed that age (OR = 0.9, 95%CI 0.82-0.99, P = 0.035) and female gender (OR = 2.42, 95%CI 1.21-4.83, P = 0.013) were independent risk factors for CPPV, and the incidence of CPPV decreased with age. The area under the ROC curve (AUC) for the training set of the constructed model was 0.632, and the AUC for the validation set was 0.708. The Hosmer-Lemeshow goodness-of-fit test indicated good model fit (training set P = 0.085, validation set P = 0.221), and the DCA curve suggested good clinical benefit.The nomogram model developed in this study demonstrates good clinical value. Children with unilateral inguinal hernia or hydrocele who are younger in age and female gender should undergo careful intraoperative exploration for the presence of CPPV. What is Known: • The probability of developing inguinal hernia in children with CPPV is 11%-25%, and redo surgery can increase surgical risks and financial burden. • The risk factors of unilateral inguinal hernia combined with CPPV are controversial. What is New: • Age and female gender are independent risk factors for CPPV. • A nomogram prediction model was constructed to provide a theoretical basis as well as an assessment tool for preoperative evaluation of whether children with unilateral indirect inguinal hernia are susceptible to CPPV.

RESUMEN

INTRODUCTION: Evidence about the advantage of Lichtenstein's repair, the guidelines' recommended technique, is scarce regarding postoperative chronic inguinal pain (CPIP). The primary aim of this study was to compare CPIP in patients undergoing Lichtenstein versus other techniques. METHODS: Prospective multicentric cohort study including consecutive adults undergoing elective inguinal hernia repair in Portuguese hospitals (October - December 2019). Laparoscopic and mesh-free hernia repairs were excluded. The primary outcome was postoperative pain at three months, defined as a score of ≥ 3/10 in the European Hernia Society Quality of Life score pain domain. The secondary outcome was 30-day postoperative complications. RESULTS: Eight hundred and sixty-nine patients from 33 hospitals were included. Most were men (90.4%) and had unilateral hernias (88.6%). Overall, 53.6% (466/869) underwent Lichtenstein's repair, and 46.4% (403/869) were treated with other techniques, of which 83.9% (338/403) were plug and patch. The overall rate of CPIP was 16.6% and 12.2% of patients had surgical complications. The unadjusted risk was similar for CPIP (OR 0.76, p = 0.166, CI 0.51 - 1.12) and postoperative complications (OR 1.06, p = 0.801, CI 0.69 - 1.60) between Lichtenstein and other techniques. After adjustment, the risk was also similar for CPIP (OR 0.83, p = 0.455, CI 0.51 - 1.34) and postoperative complications (OR 1.14, p = 0.584, CI 0.71 - 1.84). CONCLUSION: The Lichtenstein technique was not associated with lower CPIP and showed comparable surgical complications. Further investigation as- sessing long term outcomes is necessary to fully assess the benefits of the Lichtenstein technique regarding CPIP.
