Lee SR. Characteristics of pantaloon inguinal hernia and evaluation of added laparoscopic iliopubic tract repair to transabdominal preperitoneal hernioplasty: a retrospective observational study. Ann Surg Treat Res 2024; 106:361-368. [PMID: 38868584 PMCID: PMC11164662 DOI: 10.4174/astr.2024.106.6.361] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 02/18/2024] [Accepted: 03/11/2024] [Indexed: 06/14/2024] Open
Abstract
Purpose Pantaloon hernia (PH), defined as concurrent ipsilateral direct and indirect inguinal hernias, is known for its high postoperative recurrence rate. This study retrospectively investigated the characteristics of PHs and evaluated the safety and efficacy of incorporating laparoscopic iliopubic tract repair (IPTR) into transabdominal preperitoneal (TAPP) hernioplasty. Methods A total of 3,355 patients who underwent TAPP hernioplasty for groin hernias between October 2014 and December 2021 were analyzed. These patients were divided into 2 groups: PH (97 patients) and non-PH (3,258 patients). The PH group was further subdivided based on the surgical technique used: TAPP hernioplasty without IPTR (TAPP group, 39 patients) and TAPP hernioplasty with IPTR for defect closure (TAPP + IPTR group, 58 patients). Results The study included 93 male and 4 female patients with PH. Patients with PH were generally older and predominantly male compared to the non-PH group. The recurrence rate in the PH group was notably higher than in the non-PH group (2.1% [2 of 97] vs. 0.2% [6 of 3,258], respectively; P = 0.007). Among the PH group, reoperations were more frequent in the TAPP group compared to the TAPP + IPTR group (10.3% [4 of 39] vs. 0% [0 of 58], respectively; P = 0.048). The reasons for reoperation in the PH group included recurrences (2 patients), mesh bulge (1 patient), and chronic seroma (1 patient). Conclusion TAPP + IPTR hernioplasty is an acceptable approach in PH treatment, reducing reoperation.

Current prevalence of perioperative early venous thromboembolism and risk factors in Chinese adult patients with inguinal hernia (CHAT-1). Sci Rep 2020; 10:12667. [PMID: 32728130 PMCID: PMC7391649 DOI: 10.1038/s41598-020-69453-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2019] [Accepted: 07/13/2020] [Indexed: 11/08/2022] Open
Abstract
Venous thromboembolism (VTE) is an important postoperative complication. We investigated and analyzed the current inguinal hernia treatment methods and occurrence of early postoperative VTE in Chinese adults. This study involved data for patients with inguinal hernia hospitalized in 58 general hospitals in mainland China from January 1st, 2017 to December 31st, 2017. Data were retrospectively analyzed using a questionnaire. After data inputting and cleaning, we stratified and statistically analyzed patients' data using Caprini scores to create a high-, middle-, and low-risk group. A total of 14,322 patients with inguinal hernia were admitted to the 58 participating hospitals. After data collation and cleaning, 13,886 patients (97.0%) met our inclusion and exclusion criteria. The percentages of laparoscopic surgery and open surgery were 51.2% and 48.8%, respectively. 16 VTEs occurred during the hospitalization, accounting for 0.1% of all adverse events (95% confidence interval (CI) 0.11-0.13). The incidence of VTE was 0.2% (95% CI 0.18-0.2) in the high-risk group and 0.02% (95% CI 0.01-0.03) in the middle-risk group, based on Caprini scoring, with a significant difference (p < 0.0001). No VTE occurred in the low-risk group. Only 3,250 (23.4%) patients underwent Caprini risk assessment regarding treatment, with 13.2% receiving any prevention and only 1.2% receiving appropriate prevention. The treatment of inguinal hernia in Chinese adults has progressed somewhat; however, the evaluation and prevention of perioperative VTE was seriously neglected, in our study, and the incidence of postoperative VTE was underestimated postoperatively. Risk factors continue to be inadequately considered.

Abstract
BACKGROUND Our objective was to investigate the clinical characteristics of laparoscopic repair for groin hernias in female patients. STUDY DESIGN The clinical data of 316 female patients (341 hernias) who underwent laparoscopic inguinal hernia repair at Shanghai Minimally Invasive Surgery Center between January 2001 and December 2015 was analyzed retrospectively. The operation-related data were to provide an overview of female groin hernias, preferred surgical approach, and the management of round ligament of uterus. RESULTS There were 274 transabdominal preperitoneal patch plastic repairs and 67 total extraperitoneal repairs performed on 257 and 59 patients, respectively. The median follow-up period was 48 months. Fifty-eight femoral hernias were noted in 52 patients, of which 18 femoral hernias were incarcerated. Cysts on the round ligament of uterus were found in 39 patients, and most of them underwent laparoscopic resection. Round ligaments of uterus were preserved in 152 patients and transected in 162 patients. The preservation group requires longer operation time and trickier surgical technique. None of the cases was converted to laparotomy. All patients returned to normal activity soon and no recurrence was noted during follow-up. CONCLUSIONS Laparoscopic inguinal hernia repair is well adopted around the world. Meanwhile, there still remain questions to be discussed in female patients. Based on this study, the round ligament cyst could be resected while the operation. Either "open and suture" or keyhole technique will be available to preserve the round ligament of uterus.

Abstract
OBJECTIVE We aimed to compare the clinical outcome of titanium-coated mesh and polypropylene mesh in laparoscopic inguinal hernia repair. METHODS A total of 102 patients who received laparoscopic inguinal hernia repair in January-June 2016 in Beijing Chao-Yang Hospital were enrolled in this study. Patients were randomly divided into two groups, receiving either titanium-coated mesh (n = 50) or standard polypropylene mesh (n = 52). Multiple clinical parameters were collected and analyzed, including clinical manifestations, operative time, intraoperative blood loss, hospital stay, hospital cost, recovery time, and postoperative complications. RESULTS All procedures were completed. A statistical difference between two groups was not identified in regards to operative time, intraoperative blood loss, hospital stay, and recovery time (P > 0.05). Three cases with seroma and 15 with foreign body sensation were reported in the titanium-coated mesh group; 9 cases with seroma and 17 with foreign body sensation were reported in the standard polypropylene mesh group. There was no significant difference in the incidence of seroma and/or foreign body sensation. A lower hospital cost but longer recovery period was documented in the standard polypropylene mesh group (P < 0.05). No recurrence, infection or chronic pain was observed during 1-year follow-up in both groups. CONCLUSION Titanium-coated mesh possesses comparable clinical qualities as the standard polypropylene mesh but with a shorter recovery period. Therefore, this mesh is promising for clinical practice though the cost is higher than the standard polypropylene mesh.

Abstract
Laparoscopic techniques are now well pervading in the treatment of inguinal hernia. This study aims to investigate the laparoscopic strategy for recurrent inguinal hernia repair. Laparoscopic technique was retrospectively applied to 330 patients with 352 recurrent inguinal hernias in the past 14 years. The surgical strategies were further evaluated. There were 22 cases with bilateral recurrent hernias, whereas the rest 308 cases with unilateral disorders. Patients were further categorized by previous repair approaches as high ligation, sclerotherapy, conventional suture repair, Lichtenstein repair, plug and patch repair, and preperitoneal repair. All cases were successfully repaired by laparoscopic approaches including transabdominal preperitoneal (TAPP) (288 cases), totally extraperitoneal (50 cases), and intraperitoneal onlay mesh (14 cases). The median operation duration was 39.5 ± 13.4 minutes. The average Visual Analog Scales score on postoperative day 1 was 2.4 ± 1.1. The median follow-up time was 36 (14–61) months. There was one case of recurrence during the follow-ups. One severe complication, i.e., bowel injury, was observed and cured, whereas other complications were as follows: 22 seroma, 8 urinary retention, 3 transient paresthesia, and 1 ileus. Laparoscopic procedures for recurrence inguinal hernia are safe and applicable. A surgeon can choose to reinforce the myopectineal orifice or only fix the hernia defect accordingly. The strategy of choosing TAPP and/or totally extraperitoneal depends on the type of previous repair, the exact anatomical position of the previous implanted mesh, and more importantly, the surgeon's experience. Moreover, the intraperitoneal onlay mesh technique can be regarded as a backup option for TAPP in certain cases.

Abstract
INTRODUCTION Worldwide, more than 20 million patients undergo groin hernia repair annually. The many different approaches, treatment indications and a significant array of techniques for groin hernia repair warrant guidelines to standardize care, minimize complications, and improve results. The main goal of these guidelines is to improve patient outcomes, specifically to decrease recurrence rates and reduce chronic pain, the most frequent problems following groin hernia repair. They have been endorsed by all five continental hernia societies, the International Endo Hernia Society and the European Association for Endoscopic Surgery. METHODS An expert group of international surgeons (the HerniaSurge Group) and one anesthesiologist pain expert was formed. The group consisted of members from all continents with specific experience in hernia-related research. Care was taken to include surgeons who perform different types of repair and had preferably performed research on groin hernia surgery. During the Group's first meeting, evidence-based medicine (EBM) training occurred and 166 key questions (KQ) were formulated. EBM rules were followed in complete literature searches (including a complete search by The Dutch Cochrane database) to January 1, 2015 and to July 1, 2015 for level 1 publications. The articles were scored by teams of two or three according to Oxford, SIGN and Grade methodologies. During five 2-day meetings, results were discussed with the working group members leading to 136 statements and 88 recommendations. Recommendations were graded as "strong" (recommendations) or "weak" (suggestions) and by consensus in some cases upgraded. In the Results and summary section below, the term "should" refers to a recommendation. The AGREE II instrument was used to validate the guidelines. An external review was performed by three international experts. They recommended the guidelines with high scores. The risk factors for inguinal hernia (IH) include: family history, previous contra-lateral hernia, male gender, age, abnormal collagen metabolism, prostatectomy, and low body mass index. Peri-operative risk factors for recurrence include poor surgical techniques, low surgical volumes, surgical inexperience and local anesthesia. These should be considered when treating IH patients. IH diagnosis can be confirmed by physical examination alone in the vast majority of patients with appropriate signs and symptoms. Rarely, ultrasound is necessary. Less commonly still, a dynamic MRI or CT scan or herniography may be needed. The EHS classification system is suggested to stratify IH patients for tailored treatment, research and audit. Symptomatic groin hernias should be treated surgically. Asymptomatic or minimally symptomatic male IH patients may be managed with "watchful waiting" since their risk of hernia-related emergencies is low. The majority of these individuals will eventually require surgery; therefore, surgical risks and the watchful waiting strategy should be discussed with patients. Surgical treatment should be tailored to the surgeon's expertise, patient- and hernia-related characteristics and local/national resources. Furthermore, patient health-related, life style and social factors should all influence the shared decision-making process leading up to hernia management. Mesh repair is recommended as first choice, either by an open procedure or a laparo-endoscopic repair technique. One standard repair technique for all groin hernias does not exist. It is recommended that surgeons/surgical services provide both anterior and posterior approach options. Lichtenstein and laparo-endoscopic repair are best evaluated. Many other techniques need further evaluation. Provided that resources and expertise are available, laparo-endoscopic techniques have faster recovery times, lower chronic pain risk and are cost effective. There is discussion concerning laparo-endoscopic management of potential bilateral hernias (occult hernia issue). After patient consent, during TAPP, the contra-lateral side should be inspected. This is not suggested during unilateral TEP repair. After appropriate discussions with patients concerning results tissue repair (first choice is the Shouldice technique) can be offered. Day surgery is recommended for the majority of groin hernia repair provided aftercare is organized. Surgeons should be aware of the intrinsic characteristics of the meshes they use. Use of so-called low-weight mesh may have slight short-term benefits like reduced postoperative pain and shorter convalescence, but are not associated with better longer-term outcomes like recurrence and chronic pain. Mesh selection on weight alone is not recommended. The incidence of erosion seems higher with plug versus flat mesh. It is suggested not to use plug repair techniques. The use of other implants to replace the standard flat mesh in the Lichtenstein technique is currently not recommended. In almost all cases, mesh fixation in TEP is unnecessary. In both TEP and TAPP it is recommended to fix mesh in M3 hernias (large medial) to reduce recurrence risk. Antibiotic prophylaxis in average-risk patients in low-risk environments is not recommended in open surgery. In laparo-endoscopic repair it is never recommended. Local anesthesia in open repair has many advantages, and its use is recommended provided the surgeon is experienced in this technique. General anesthesia is suggested over regional in patients aged 65 and older as it might be associated with fewer complications like myocardial infarction, pneumonia and thromboembolism. Perioperative field blocks and/or subfascial/subcutaneous infiltrations are recommended in all cases of open repair. Patients are recommended to resume normal activities without restrictions as soon as they feel comfortable. Provided expertise is available, it is suggested that women with groin hernias undergo laparo-endoscopic repair in order to decrease the risk of chronic pain and avoid missing a femoral hernia. Watchful waiting is suggested in pregnant women as groin swelling most often consists of self-limited round ligament varicosities. Timely mesh repair by a laparo-endoscopic approach is suggested for femoral hernias provided expertise is available. All complications of groin hernia management are discussed in an extensive chapter on the topic. Overall, the incidence of clinically significant chronic pain is in the 10-12% range, decreasing over time. Debilitating chronic pain affecting normal daily activities or work ranges from 0.5 to 6%. Chronic postoperative inguinal pain (CPIP) is defined as bothersome moderate pain impacting daily activities lasting at least 3 months postoperatively and decreasing over time. CPIP risk factors include: young age, female gender, high preoperative pain, early high postoperative pain, recurrent hernia and open repair. For CPIP the focus should be on nerve recognition in open surgery and, in selected cases, prophylactic pragmatic nerve resection (planned resection is not suggested). It is suggested that CPIP management be performed by multi-disciplinary teams. It is also suggested that CPIP be managed by a combination of pharmacological and interventional measures and, if this is unsuccessful, followed by, in selected cases (triple) neurectomy and (in selected cases) mesh removal. For recurrent hernia after anterior repair, posterior repair is recommended. If recurrence occurs after a posterior repair, an anterior repair is recommended. After a failed anterior and posterior approach, management by a specialist hernia surgeon is recommended. Risk factors for hernia incarceration/strangulation include: female gender, femoral hernia and a history of hospitalization related to groin hernia. It is suggested that treatment of emergencies be tailored according to patient- and hernia-related factors, local expertise and resources. Learning curves vary between different techniques. Probably about 100 supervised laparo-endoscopic repairs are needed to achieve the same results as open mesh surgery like Lichtenstein. It is suggested that case load per surgeon is more important than center volume. It is recommended that minimum requirements be developed to certify individuals as expert hernia surgeon. The same is true for the designation "Hernia Center". From a cost-effectiveness perspective, day-case laparoscopic IH repair with minimal use of disposables is recommended. The development and implementation of national groin hernia registries in every country (or region, in the case of small country populations) is suggested. They should include patient follow-up data and account for local healthcare structures. A dissemination and implementation plan of the guidelines will be developed by global (HerniaSurge), regional (international societies) and local (national chapters) initiatives through internet websites, social media and smartphone apps. An overarching plan to improve access to safe IH surgery in low-resource settings (LRSs) is needed. It is suggested that this plan contains simple guidelines and a sustainability strategy, independent of international aid. It is suggested that in LRSs the focus be on performing high-volume Lichtenstein repair under local anesthesia using low-cost mesh. Three chapters discuss future research, guidelines for general practitioners and guidelines for patients. CONCLUSIONS The HerniaSurge Group has developed these extensive and inclusive guidelines for the management of adult groin hernia patients. It is hoped that they will lead to better outcomes for groin hernia patients wherever they live. More knowledge, better training, national audit and specialization in groin hernia management will standardize care for these patients, lead to more effective and efficient healthcare and provide direction for future research.
