European Association for Endoscopic Surgery (EAES) consensus on Indocyanine Green (ICG) fluorescence-guided surgery.

BACKGROUND: In recent years, the use of Indocyanine Green (ICG) fluorescence-guided surgery during open and laparoscopic procedures has exponentially expanded across various clinical settings. The European Association of Endoscopic Surgery (EAES) initiated a consensus development conference on this topic with the aim of creating evidence-based statements and recommendations for the surgical community. METHODS: An expert panel of surgeons has been selected and invited to participate to this project. Systematic reviews of the PubMed, Embase and Cochrane libraries were performed to identify evidence on potential benefits of ICG fluorescence-guided surgery on clinical practice and patient outcomes. Statements and recommendations were prepared and unanimously agreed by the panel; they were then submitted to all EAES members through a two-rounds online survey and results presented at the EAES annual congress, Barcelona, November 2021. RESULTS: A total of 18,273 abstracts were screened with 117 articles included. 22 statements and 16 recommendations were generated and approved. In some areas, such as the use of ICG fluorescence-guided surgery during laparoscopic cholecystectomy, the perfusion assessment in colorectal surgery and the search for the sentinel lymph nodes in gynaecological malignancies, the large number of evidences in literature has allowed us to strongly recommend the use of ICG for a better anatomical definition and a reduction in post-operative complications. CONCLUSIONS: Overall, from the systematic literature review performed by the experts panel and the survey extended to all EAES members, ICG fluorescence-guided surgery could be considered a safe and effective technology. Future robust clinical research is required to specifically validate multiple organ-specific applications and the potential benefits of this technique on clinical outcomes.

Reporting guideline for interventional trials of primary and incisional ventral hernia repair.

BACKGROUND: Primary and incisional ventral hernia trials collect unstandardized inconsistent data, limiting data interpretation and comparison. This study aimed to create two minimum data sets for primary and incisional ventral hernia interventional trials to standardize data collection and improve trial comparison. To support these data sets, standardized patient-reported outcome measures and trial methodology criteria were created. METHODS: To construct these data sets, nominal group technique methodology was employed, involving 15 internationally recognized abdominal wall surgeons and two patient representatives. Initially a maximum data set was created from previous systematic and panellist reviews. Thereafter, three stages of voting took place: stage 1, selection of the number of variables for data set inclusion; stage 2, selection of variables to be included; and stage 3, selection of variable definitions and detection methods. A steering committee interpreted and analysed the data. RESULTS: The maximum data set contained 245 variables. The three stages of voting commenced in October 2019 and had been completed by July 2020. The final primary ventral hernia data set included 32 variables, the incisional ventral hernia data set included 40 variables, the patient-reported outcome measures tool contained 25 questions, and 40 methodological criteria were chosen. The best known variable definitions were selected for accurate variable description. CT was selected as the optimal preoperative descriptor of hernia morphology. Standardized follow-up at 30 days, 1 year, and 5 years was selected. CONCLUSION: These minimum data sets, patient-reported outcome measures, and methodological criteria have allowed creation of a manual for investigators aiming to undertake primary ventral hernia or incisional ventral hernia interventional trials. Adopting these data sets will improve trial methods and comparisons.

International classification of abdominal wall planes (ICAP) to describe mesh insertion for ventral hernia repair.

BACKGROUND: Nomenclature for mesh insertion during ventral hernia repair is inconsistent and confusing. Several terms, including 'inlay', 'sublay' and 'underlay', can refer to the same anatomical planes in the indexed literature. This frustrates comparisons of surgical practice and may invalidate meta-analyses comparing surgical outcomes. The aim of this study was to establish an international classification of abdominal wall planes. METHODS: A Delphi study was conducted involving 20 internationally recognized abdominal wall surgeons. Different terms describing anterior abdominal wall planes were identified via literature review and expert consensus. The initial list comprised 59 possible terms. Panellists completed a questionnaire that suggested a list of options for individual abdominal wall planes. Consensus on a term was predefined as occurring if selected by at least 80 per cent of panellists. Terms scoring less than 20 per cent were removed. RESULTS: Voting started August 2018 and was completed by January 2019. In round 1, 43 terms (73 per cent) were selected by less than 20 per cent of panellists and 37 new terms were suggested, leaving 53 terms for round 2. Four planes reached consensus in round 2, with the terms 'onlay', 'inlay', 'preperitoneal' and 'intraperitoneal'. Thirty-five terms (66 per cent) were selected by less than 20 per cent of panellists and were removed. After round 3, consensus was achieved for 'anterectus', 'interoblique', 'retro-oblique' and 'retromuscular'. Default consensus was achieved for the 'retrorectus' and 'transversalis fascial' planes. CONCLUSION: Consensus concerning abdominal wall planes was agreed by 20 internationally recognized surgeons. Adoption should improve communication and comparison among surgeons and research studies.

ANTECEDENTES: La nomenclatura de la inserción de una malla para la reparación de una hernia incisional ventral (ventral hernia, VH) es inconsistente y confusa. En la literatura indexada se usan varios términos, tales como 'inlay', 'sublay', y 'underlay' que pueden referirse a los mismos planos anatómicos. Este hecho frustra las comparaciones de técnicas quirúrgicas e invalida los metaanálisis que comparan resultados quirúrgicos en función del plano de inserción de la malla. En consecuencia, el objetivo de este estudio fue establecer una clasificación internacional de los planos de la pared abdominal (International Classification of Abdominal Wall Planes, ICAP). MÉTODOS: Se realizó un estudio Delphi, en el que participaron 20 cirujanos de pared abdominal reconocidos internacionalmente. Se identificaron diferentes términos que describían los planos de la pared abdominal anterior mediante la revisión de la literatura y el consenso de expertos. La lista inicial incluía 59 términos posibles. Los panelistas completaron un cuestionario que sugería una lista de opciones para los planos individuales de la pared abdominal. El consenso sobre un término fue predefinido cuando dicho término había sido seleccionado por ≥ 80% de panelistas. Se eliminaron los términos con una puntuación < 20%. RESULTADOS: La votación comenzó en agosto de 2018 y se completó en enero de 2019. Durante la Ronda 1, 43 (73%) términos fueron seleccionados por < 20% de los panelistas y se sugirieron 37 términos nuevos, dejando 53 términos para la Ronda 2. Cuatro planos alcanzaron un consenso en la Ronda 2 con los términos 'onlay', 'inlay', 'pre-peritoneal' e 'intra-peritoneal'. Treinta y cinco (66%) términos fueron seleccionados por < 20% de los panelistas y fueron eliminados. Después de la Ronda 3, se logró un consenso para 'anterectus' (ante-recto), 'interoblique' (inter-oblicuo), 'retrooblique' (retro-oblicuo) y 'retromuscular'. Se alcanzó un consenso por defecto para los planos 'retrorectus' (retro-recto) y 'transversalis fascial' (fascial transverso). CONCLUSIÓN: La ICAP ha sido desarrollada por el consenso de 20 cirujanos reconocidos internacionalmente. Su implementación debería mejorar la comunicación y la comparación entre cirujanos y estudios de investigación.

META Score: An International Consensus Scoring System on Mesh-Tissue Adhesions.

BACKGROUND: Currently, the lack of consensus on postoperative mesh-tissue adhesion scoring leads to incomparable scientific results. The aim of this study was to develop an adhesion score recognized by experts in the field of hernia surgery. METHODS: Authors of three or more previously published articles on both mesh-tissue adhesion scores and postoperative adhesions were marked as experts. They were queried on seven items using a modified Delphi method. The items concerned the utility of adhesion scoring models, the appropriateness of macroscopic and microscopic variables, the range and use of composite scores or subscores, adhesion-related complications and follow-up length. This study comprised two questionnaire-based rounds and one consensus meeting. RESULTS: The first round was completed by 23 experts (82%), the second round by 18 experts (64%). Of those 18 experts, ten were able to participate in the final consensus meeting and all approved the final proposal. From a total of 158 items, consensus was reached on 90 items. The amount of mesh surface covered with adhesions, tenacity and thickness of adhesions and organ involvement was concluded to be a minimal set of variables to be communicated separately in each future study on mesh adhesions. CONCLUSION: The MEsh Tissue Adhesion scoring system is the first consensus-based scoring system with a wide backing of renowned experts and can be used to assess mesh-related adhesions. By including this minimal set of variables in future research interstudy comparability and objectivity can be increased and eventually linked to clinically relevant outcomes.

Update of Guidelines for laparoscopic treatment of ventral and incisional abdominal wall hernias (International Endohernia Society (IEHS)): Part B.

In 2014 the International Endohernia Society (IEHS) published the first international "Guidelines for laparoscopic treatment of ventral and incisional abdominal wall hernias". Guidelines reflect the currently best available evidence in diagnostics and therapy and give recommendations to help surgeons to standardize their techniques and to improve their results. However, science is a dynamic field which is continuously developing. Therefore, guidelines require regular updates to keep pace with the evolving literature. METHODS: For the development of the original guidelines all relevant literature published up to year 2012 was analyzed using the ranking of the Oxford Centre for Evidence-Based-Medicine. For the present update all of the previous authors were asked to evaluate the literature published during the recent years from 2012 to 2017 and revise their statements and recommendations given in the initial guidelines accordingly. In two Consensus Conferences (October 2017 Beijing, March 2018 Cologne) the updates were presented, discussed, and confirmed. To avoid redundancy, only new statements or recommendations are included in this paper. Therefore, for full understanding both of the guidelines, the original and the current, must be read. In addition, the new developments in repair of abdominal wall hernias like surgical techniques within the abdominal wall, release operations (transversus muscle release, component separation), Botox application, and robot-assisted repair methods were included. RESULTS: Due to an increase of the number of patients and further development of surgical techniques, repair of primary and secondary abdominal wall hernias attracts increasing interests of many surgeons. Whereas up to three decades ago hernia-related publications did not exceed 20 per year, currently this number is about 10-fold higher. Recent years are characterized by the advent of new techniques-minimal invasive techniques using robotics and laparoscopy, totally extraperitoneal repairs, novel myofascial release techniques for optimal closure of large defects, and Botox for relaxing the abdominal wall. Furthermore, a concomitant rectus diastasis was recognized as a significant risk factor for recurrence. Despite still insufficient evidence with respect to these new techniques it seemed to us necessary to include them in the update to stimulate surgeons to do research in these fields. CONCLUSION: Guidelines are recommendations based on best available evidence intended to help the surgeon to improve the quality of his daily work. However, science is a continuously evolving process, and as such guidelines should be updated about every 3 years. For a comprehensive reference, however, it is suggested to read both the initially guidelines published in 2014 together with the update. Moreover, the presented update includes also techniques which were not known 3 years before.

ECSPECT prospective multicentre registry for single-port laparoscopic colorectal procedures.

BACKGROUND: The international multicentre registry ECSPECT (European Consensus of Single Port Expertise in Colorectal Treatment) was established to evaluate the general feasibility and safety of single-port colorectal surgery with regard to preoperative risk assessment. METHODS: Consecutive patients undergoing single-port colorectal surgery were enrolled from 11 European centres between March 2010 and March 2014. Data were analysed to assess patient-, technique- and procedure-dependent parameters. A validated sex-adjusted risk chart was developed for prediction of single-port colorectal surgery-related conversion and complications. RESULTS: Some 1769 patients were enrolled, 937 with benign and 832 with malignant conditions. Procedures were completed without additional trocars in 1628 patients (92·0 per cent). Conversion to open surgery was required in 75 patients (4·2 per cent) and was related to male sex and ASA fitness grade exceeding I. Conversions were more frequent in pelvic procedures involving the rectum compared with abdominal procedures (8·1 versus 3·2 per cent; odds ratio 2·69, P < 0·001). Postoperative complications were observed in a total of 224 patients (12·7 per cent). Independent predictors of complications included male sex (P < 0·001), higher ASA grade (P = 0·006) and rectal procedures (P = 0·002). The overall 30-day mortality rate was 0·5 per cent (8 of 1769 patients); three deaths (0·2 per cent; 1 blood loss, 2 leaks) were attributable to surgical causes. CONCLUSION: The feasibility and safety, conversion and complication profile demonstrated here provides guidance for patient selection.

Closed-loop gastric electrical stimulation versus laparoscopic adjustable gastric band for the treatment of obesity: a randomized 12-month multicenter study.

OBJECTIVE: To compare the weight loss, change in quality of life (QOL) and safety of closed-loop gastric electrical stimulation (CLGES) versus adjustable gastric band (LAGB) in the treatment of obesity. METHODS: This multicenter, randomized, non-inferiority trial randomly assigned the patients in a 2:1 ratio to laparoscopic CLGES versus LAGB and followed them for 1 year. We enrolled 210 patients, of whom 50 were withdrawn preoperatively. Among 160 remaining patients (mean age=39±11 years; 75% women; mean body mass index=43±6 kg m-2) 106 received CLGES and 54 received LAGB. The first primary end point was non-inferiority of CLGES versus LAGB, ascertained by the proportion of patients who, at 1 year, fulfilled: (a) a ⩾20% excess weight loss (EWL); (b) no major device- or procedure-related adverse event (AE); and (c) no major, adverse change in QOL. Furthermore, ⩾50% of patients had to reach ⩾25% EWL. The incidence and seriousness of all AE were analyzed and compared using Mann-Whitney's U-test. RESULTS: At 1 year, the proportions of patients who reached all components of the primary study end point were 66.7 and 73.0% for the LAGB and CLGES group, respectively, with a difference of -6.3% and an upper 95% CI of 7.2%, less than the predetermined 10% margin for confirming the non-inferiority of CLGES. The second primary end point was also met, as 61.3% of patients in the CLGES group reached ⩾25% EWL (lower 95% CI=52.0%; P<0.01). QOL improved significantly and similarly in both groups. AE were significantly fewer and less severe in the CLGES than in the LAGB group (P<0.001). CONCLUSIONS AND RELEVANCE: This randomized study confirmed the non-inferiority of CLGES compared with LAGB based on the predetermined composite end point. CLGES was associated with significantly fewer major AE.

Effect of bariatric surgery on microvascular dysfunction associated to metabolic syndrome: a 12-month prospective study.

OBJECTIVE: To prospectively evaluate the effect of weight loss after bariatric surgery on microvascular function in morbidly obese patients with and without metabolic syndrome (MetS). METHODS: A cohort of morbidly obese patients with and without MetS was studied before surgery and after 12 months of surgery. Healthy lean controls were also examined. Microvascular function was assessed by postocclusive reactive hyperemia (PORH) at forearm skin evaluated by laser Doppler flowmetry (LDF). Cutaneous vascular conductance (CVC) was calculated from laser-Doppler skin blood flow and blood pressure. Regression analysis was performed to assess the contribution of different clinical, metabolic and biochemical parameters to microvascular function. RESULTS: Before surgery, 62 obese patients, 39 with MetS and 23 without MetS, and 30 lean control subjects were analyzed. The absolute area under the hyperemic curve (AUC(H)) CVC of PORH was significantly decreased in obese patients compared with lean control subjects. One year after surgery, AUC(H) CVC significantly increased in patients free of MetS, including patients that had MetS before surgery. In contrast, AUC(H) CVC did not significantly change in patients in whom MetS persisted after surgery. Stepwise multivariate regression analysis showed that only changes in HDL cholesterol (HDL-C) and oxidized LDL (oxLDL) independently predicted improvement of AUC(H) after surgery. These two variables together accounted for 40.9% of the variability of change in AUC(H) CVC after surgery. CONCLUSIONS: Bariatric surgery could significantly improve microvascular dysfunction in obese patients, but only in patients free of MetS after surgery. Improvement of microvascular dysfunction is strictly associated to postoperative increase in HDL-C levels and decrease in oxLDL levels.

Guidelines for laparoscopic treatment of ventral and incisional abdominal wall hernias (International Endohernia Society (IEHS)-part 1.

Guidelines are increasingly determining the decision process in day-to-day clinical work. Guidelines describe the current best possible standard in diagnostics and therapy. They should be developed by an international panel of experts, whereby alongside individual experience, above all, the results of comparative studies are decisive. According to the results of high-ranking scientific studies published in peer-reviewed journals, statements and recommendations are formulated, and these are graded strictly according to the criteria of evidence-based medicine. Guidelines can therefore be valuable in helping particularly the young surgeon in his or her day-to-day work to find the best decision for the patient when confronted with a wide and confusing range of options. However, even experienced surgeons benefit because by virtue of a heavy workload and commitment, they often find it difficult to keep up with the ever-increasing published literature. All guidelines require regular updating, usually every 3 years, in line with progress in the field. The current Guidelines focus on technique and perioperative management of laparoscopic ventral hernia repair and constitute the first comprehensive guidelines on this topic. In this issue of Surgical Endoscopy, the first part of the Guidelines is published including sections on basics, indication for surgery, perioperative management, and key points of technique. The next part (Part 2) of the Guidelines will address complications and comparisons between open and laparoscopic techniques. Part 3 will cover mesh technology, hernia prophylaxis, technique-related issues, new technologic developments, lumbar and other unusual hernias, and training/education.

Laparoscopic intracorporeal rectus aponeuroplasty (LIRA) technique versus intraperitoneal onlay mesh (IPOM plus) for ventral hernia repair: a comparative analysis.

PURPOSE: Primary aim of this study is to compare the postoperative outcomes of the laparoscopic intracorporeal rectus aponeuroplasty (LIRA) technique to the intraperitoneal onlay mesh closing the defect (IPOM plus), in terms of recurrence and bulging rates at one-year follow-up; secondary aim is to compare the postoperative complications, seroma and pain at 30 days and one-year after surgery. METHODS: Patients with midline ventral hernia of 4-10 cm in width were included. Computed tomography scan was performed before, 1 and 12 months after surgery. Pain was evaluated using the visual analogue scale. RESULTS: Forty-five and forty-seven consecutive patients underwent LIRA and IPOM plus, respectively. Preoperatively, smoke habits and chronic obstructive pulmonary disease rates were statistically significantly higher in the LIRA group (p = 0.0001 and p = 0.012, respectively). Two bulgings (4.4%) occurred in the LIRA group, while in the IPOM plus group occurred 10 bulgings (21.3%) and three recurrences (6.4%) (p = 0.017 and p = 0.085, respectively). Postoperatively, seven (15.6%, Clavien-Dindo I) and four complications (8.5%, two Clavien-Dindo I, two Clavien-Dindo III-b) occurred in the LIRA and in the IPOM plus group, respectively (p = 0.298). One month after surgery, clinical seroma, occurred in five (11.1%) and eight patients (17%) in the LIRA and in the IPOM plus group, respectively (p = 0.416). During follow-up, pain reduction occurred, without statistically significant differences. CONCLUSIONS: In this study, even if we analysed a small series, LIRA showed lower bulging and recurrence rates in comparison to IPOM plus at one-year follow-up. Further prospective studies, with a large sample of patients and longer follow-up are required to draw definitive conclusions.

Economic analysis of the robotic approach to inguinal hernia versus laparoscopic: is it sustainable for the healthcare system?

INTRODUCTION: There has been a rapid proliferation of the robotic approach to inguinal hernia, mainly in the United States, as it has shown similar outcomes to the laparoscopic approach but with a significant increase in associated costs. Our objective is to conduct a cost analysis in our setting (Spanish National Health System). MATERIALS AND METHODS: A retrospective single-center comparative study on inguinal hernia repair using a robotic approach versus laparoscopic approach. RESULTS: A total of 98 patients who underwent either robotic or laparoscopic TAPP inguinal hernia repair between October 2021 and July 2023 were analyzed. Out of these 98 patients, 20 (20.4%) were treated with the robotic approach, while 78 (79.6%) underwent the laparoscopic approach. When comparing both approaches, no significant differences were found in terms of complications, recurrences, or readmissions. However, the robotic group exhibited a longer surgical time (86 ± 33.07 min vs. 40 ± 14.46 min, p < 0.001), an extended hospital stays (1.6 ± 0.503 days vs. 1.13 ± 0.727 days, p < 0.007), as well as higher procedural costs (2318.63 ± 205.15 € vs. 356.81 ± 110.14 €, p < 0.001) and total hospitalization costs (3272.48 ± 408.49 € vs. 1048.61 ± 460.06 €, p < 0.001). These results were consistent when performing subgroup analysis for unilateral and bilateral hernias. CONCLUSIONS: The benefits observed in terms of recurrence rates and post-surgical complications do not justify the additional costs incurred by the robotic approach to inguinal hernia within the national public healthcare system. Nevertheless, it represents a simpler way to initiate the robotic learning curve, justifying its use in a training context.

Delphi consensus statement for understanding and managing the subcostal hernia: subcostal hernias collaborative report (scholar study).

INTRODUCTION: Subcostal hernias are categorized as L1 based on the European Hernia Society (EHS) classification and frequently involve M1, M2, and L2 sites. These are common after hepatopancreatic and biliary surgeries. The literature on subcostal hernias mostly comprises of retrospective reviews of small heterogenous cohorts, unsurprisingly leading to no consensus or guidelines. Given the limited literature and lack of consensus or guidelines for dealing with these hernias, we planned for a Delphi consensus to aid in decision making to repair subcostal hernias. METHODS: We adopted a modified Delphi technique to establish consensus regarding the definition, characteristics, and surgical aspects of managing subcostal hernias (SCH). It was a four-phase Delphi study reflecting the widely accepted model, consisting of: 1. Creating a query. 2. Building an expert panel. 3. Executing the Delphi rounds. 4. Analysing, presenting, and reporting the Delphi results. More than 70% of agreement was defined as a consensus statement. RESULTS: The 22 experts who agreed to participate in this Delphi process for Subcostal Hernias (SCH) comprised 7 UK surgeons, 6 mainland European surgeons, 4 Indians, 3 from the USA, and 2 from Southeast Asia. This Delphi study on subcostal hernias achieved consensus on the following areas-use of mesh in elective cases; the retromuscular position with strong discouragement for onlay mesh; use of macroporous medium-weight polypropylene mesh; use of the subcostal incision over midline incision if there is no previous midline incision; TAR over ACST; defect closure where MAS is used; transverse suturing over vertical suturing for closure of circular defects; and use of peritoneal flap when necessary. CONCLUSION: This Delphi consensus defines subcostal hernias and gives insight into the consensus for incision, dissection plane, mesh placement, mesh type, and mesh fixation for these hernias.

The laparoscopic modified Sugarbaker technique is safe and has a low recurrence rate: a multicenter cohort study.

BACKGROUND: Parastomal hernia is a frequent complication of intestinal stomata. Mesh repair gives the best results, with the mesh inserted via laparotomy or laparoscopically. It was the aim of this retrospective multicenter study to determine the early and late results of the laparoscopically performed, modified Sugarbaker technique with ePTFE mesh. METHODS: From 2005 to 2010, a total of 61 consecutive patients (mean age = 61 years), with a symptomatic parastomal hernia, underwent laparoscopic repair using the modified Sugarbaker technique with ePTFE mesh. Fifty-five patients had a colostomy, 4 patients an ileostomy, and 2 a urostomy according to Bricker. The records of the patients were reviewed with respect to patient characteristics, postoperative morbidity, and mortality. All patients underwent physical examination after a follow-up of at least 1 year to detect a recurrent hernia. Morbidity rate was 19 % and included wound infection (n = 1), ileus (n = 2), trocar site bleeding (n = 2), reintervention (n = 2), and pneumonia (n = 1). One patient died in the postoperative period due to metastasis of lung carcinoma that caused bowel obstruction. Concomitant incisional hernias were detected in 25 of 61 patients (41 %) and could be repaired at the same time in all cases. A recurrent hernia was found in three patients at physical examination, and in one patient an asymptomatic recurrence was found on a CT scan. The overall recurrence rate was 6.6 % after a mean follow-up of 26 months. CONCLUSION: The laparoscopic Sugarbaker technique is a safe procedure for repairing parastomal hernias. In our study, the overall morbidity was 19 % and the recurrence rate was 6.6 % after a mean follow-up of 26 months. Moreover, the laparoscopic approach revealed concomitant hernias in 41 % of the patients, which could be repaired successfully at the same time.

Laparoscopic approach in emergency for the treatment of acute incarcerated groin hernia: a systematic review and meta-analysis.

PURPOSE: Minimally invasive approach for acute incarcerated groin hernia repair is still debated. To clarify this debate, a literature review was performed. METHODS: Search was performed in PubMed, Embase, Scopus, Web of Science, and Cochrane databases, founding 28,183 articles. RESULTS: Fifteen articles, and 433 patients were included (16 bilateral hernia, range 3-8). Three hundred and eighty-eight (75.3%) and 103 patients (22.9%) underwent transabdominal preperitoneal and totally extraperitoneal repair, respectively, and in 5 patients, the defect was buttressed with broad ligament (1.1%) (not specified in 3 patients). Herniated structures were resected in 48 cases (range 1-9). Intraoperative complications and conversion occurred in 4 (range 0-1) and 10 (range 0-3) patients, respectively. Mean operative time and hospital stay ranged between 50 and 147 min, and 2 and 7 days, respectively. Postoperative complications ranged between 1 and 19. Five studies compared laparoscopic and open approaches (163 and 235 patients). Herniated structures were resected in 19 (11.7%) and 42 cases (17.9%) for laparoscopic and open approach, respectively (p = 0.1191). Intraoperative complications and conversion occurred in one (0.6%) and 5 (2.1%) patients (p = 0.4077), and in two (1.2%) and 19 (8.1%) patients (p = 0.0023), in case of laparoscopic or open approach, respectively. Mean operative time and hospital stay were 94.4 ± 40.2 and 102.8 ± 43.7 min, and 4.8 ± 2.2 and 11 ± 3.1 days, in laparoscopic or open approach, respectively. Sixteen (9.8%) and 57 (24.3%) postoperative complications occurred. CONCLUSION: Laparoscopy seems to be a safe and feasible approach for the treatment of acute incarcerated groin hernia. Further studies are required for definitive conclusions.
