Incidence and Risk Factors of Incisional Hernia After Single-Incision Endoscopic Surgery.

Introduction: Abdominal wall complications are one of the most controversial issues regarding single-incision endoscopic surgery. The aim of this study was to analyze the incidence and risk factors of incisional hernia after single-incision endoscopic cholecystectomy. Materials and Methods: An observational retrospective study was performed, on a cohort of patients cholecystectomized laparoscopically through a transumbilical single incision due to gallbladder lithiasis or polyps. Postoperative complications were analyzed, with special interest in the incisional hernia rate, whose results were assessed in the long-term follow-up. Univariate and multivariate analyses were also performed to evaluate possible variables associated with the appearance of incisional hernia. Cumulative sum charts (CUSUM) were used to identify trends in the incisional hernia risk. Results: Some 109 patients were included in the study. With a mean follow-up of nearly 38 months, an incisional hernia incidence of 5.5% was found, with 67% being diagnosed during the first year of follow-up. In the Cox regression analysis, two variables showed an independent association with the emergence of incisional hernia, body mass index (hazard ratio [HR] 1.30; 95% confidence interval [CI 1.053-1.606]; P .015), and wound infection (HR 26.32; [3.186-217.40]; P .002]. CUSUM charts showed a decrease in the risk of incisional hernia after the first 10 cases. Conclusions: Single-incision endoscopic cholecystectomy is associated with a substantially high risk of postoperative incisional hernia (5.5%).

Systematic review and meta-analysis of randomized controlled trials comparing single incision versus conventional laparoscopic appendectomy.

BACKGROUND: Single incision laparoscopic appendectomy (SILA) has been proposed as an alternative to conventional laparoscopic appendectomy (CLA). OBJECTIVE: The aim of this study was to evaluate the safety and efficacy of SILA when compared with CLA through a systematic review. METHODS: We performed an electronic search of EMBASE, PubMed, MEDLINE, and Cochrane Central Register of Controlled Trials. Randomized controlled trials (RCTs) that compared SILA with CLA were included. RESULTS: Six RCTs met eligibility criteria, which included a total of 800 patients, 401 in the SILA group and 399 in the CLA group. There were no significant differences in terms of overall complications (odds ratio [OR] 0.93; 95% confidence interval [CI] 0.59-1.47; p = 0.77). SILA had a higher technical failure rate (OR 3.30; 95% CI 1.26-8.65; p = 0.01) and required a longer operative time (mean difference [MD] 4.67; 95% CI 1.76-7.57; p = 0.002). SILA was associated with better cosmetic results (standardized MD -0.4; 95% CI -0.64 to -0.16; p = 0.001) and earlier return to normal activity (MD -0.64; 95% CI -1.09 to -0.20; p = 0.005), although these advantages should be taken with caution due to the small number of studies reporting these two items and the short follow-up in the evaluation of cosmetic results. There were no significant differences in terms of postoperative pain or length of hospital stay between groups. CONCLUSIONS: SILA is comparable to CLA in selected patients, although it is associated with a higher technical failure rate and longer operative time. Further randomized trials are needed to determine if SILA really offers benefits over CLA.

Ergonomics in laparoendoscopic single-site surgery: survey results.

BACKGROUND: Ergonomic issues are frequently reported by surgeons performing laparoendoscopic single-site (LESS) surgery. However, few studies have analysed this issue. METHODS: We used a web format survey to evaluate the opinion of surgeons with experience in this laparoscopic technique. This survey collected demographic information, surgical experience, physical and psychological symptoms, and technical problems related to this type of surgery. RESULTS: Some 78 surgeons filled out the questionnaire. All participants had clinical experience in this type of laparoscopic approach, and 68 % had performed more than 30 procedures. Two or more musculoskeletal symptoms were reported during or after performing LESS surgery by 81 % of all surgeons. Surgeons with more experience in this approach reported fewer symptoms and technical difficulties. CONCLUSIONS: LESS surgery is accompanied by musculoskeletal problems and technical difficulties for surgeons. Technological advancements and greater surgical experience in the technique will alleviate these issues. More in-depth ergonomic studies are needed.

Cirugía laparoscópica a través de incisión única / Single incision laparoscopic surgery

Uno de los objetivos de las nuevas tecnologías y técnicas en cirugía mínimamente invasiva es lograr una cirugía sin o con mínimas cicatrices visibles. La cirugía a través de orificios naturales podría considerarse como un paradigma de este desarrollo pero todavía no ha sido posible su completa implantación. Sin embargo, la innovación resultante de la investigación en cirugía a través de orificios naturales ha permitido introducir una serie de «tecnologías puente» que permiten desarrollar la cirugía mínimamente invasiva con los estándares de eficacia y seguridad exigibles, siendo la cirugía laparoscópica a través de incisión única el concepto más atractivo en este momento. El objetivo de este trabajo es revisar el concepto de cirugía laparoscópica a través de incisión única y clasificar las herramientas disponibles para su implantación y desarrollo (AU)

One of the aims of the new technologies and techniques in minimally invasive surgery (MIS) is to achieve a surgery without or with minimal visible scars. Natural orifice transluminal endoscopic surgery (NOTES) might be considered to be a paradigm of this development but it has not yet been possible to implement this universally. Nevertheless, the resultant innovation of research into NOTES has enabled “bridge technologies" to be introduced that allow MIS to be developed with the required standards of efficiency and safety. The aim of this paper is to review the concept of single incision surgery and to classify the available tools for its development and implementation (AU)

La eventración paraestomal (EP) es la complicación tardía más frecuente del estoma quirúrgico. Solo un tercio de éstas se intervienen, hecho que en parte se explica por el alto índice de recidivas observadas tras la reparación. La utilización de materiales protésicos ha mejorado los resultados, aunque siguen siendo por debajo de lo ideal. Por esta razón, se ha propuesto que la mejor solución puede estar en prevenir la aparición de la EP. Varios trabajos muestran resultados prometedores con reducciones muy llamativas en el porcentaje de EP al colocar una prótesis periestomal profiláctica. En este artículo presentamos una revisión de los factores de riesgo asociados a la EP y una clasificación de la diversidad de técnicas de reparación existentes, y se propone un algoritmo para el tratamiento de la EP, incluyendo la prevención de esta (AU) / Parastomal hernia (PH) is the most common delayed complication in stoma surgery. Only a third of these are operated on, something which is partly explained by the high recurrence rate observed after repair. The use of prosthetic materials has improved the results, although they continue to be below the ideal. For this reason, it has been proposed that the best solution may be in preventing the PH. Several studies show promising results, with very marked reductions in the percentage of IH, on placing a prophylactic peristomal prosthesis. In this article we present a review of the risk factors associated with PH, a classification of the existing diversity of repair techniques, and an algorithm is proposed for the management of PH, including its prevention (AU)
