Specifically, EndoDigest automatically provides short video clips to effectively document the critical view of safety (CVS) in laparoscopic cholecystectomy (LC). The aim of the present study is to validate EndoDigest on a multicentric dataset of LC videos. LC videos from 4 centers were manually annotated with the time of the cystic duct division and an assessment of CVS criteria. Incomplete recordings, bailout procedures and procedures with an intraoperative cholangiogram were excluded. EndoDigest leveraged predictions of deep learning models for workflow analysis in a rule-based inference system designed to estimate the time of the cystic duct division. Performance was assessed by computing the error in estimating the manually annotated time of the cystic duct division. To provide concise video documentation of CVS, EndoDigest extracted video clips showing the 2 min preceding and the 30 s following the predicted cystic duct division. The relevance of the documentation was evaluated by assessing CVS in automatically extracted 2.5-min-long video clips. 144 of the 174 LC videos from 4 centers were analyzed. EndoDigest located the time of the cystic duct division with a mean error of 124.0 ± 270.6 s despite the use of fluorescent cholangiography in 27 procedures and great variations in surgical workflows across centers. The surgical evaluation found that 108 (75.0%) of the automatically extracted short video clips documented CVS effectively. EndoDigest was robust enough to reliably locate the time of the cystic duct division and efficiently video document CVS despite the highly variable workflows. Training specifically on data from each center could improve results; however, this multicentric validation shows the potential for clinical translation of this surgical data science tool to efficiently document surgical safety.

Our aim was to demonstrate the feasibility and accuracy of LTG in gastric cancer with D2 lymphadenectomy. Material and methods: Eighty-eight LTG and four laparoscopic remnant gastrectomies (LRGs) were performed over>12 years. The median patient age was 64 years, and the male/female ratio was 1.49/1. Eighty-seven patients had a D2 and only five patients

Systematic review of PubMed and Scopus from 2010 onwards. Studies included both open (OS) and laparoscopic (LS). The primary outcome was incidence of IH 12 months after index procedure, secondary outcomes were the study features and their influence on reported proportion of IH. Random effects models were used to calculate pooled proportions. Meta-regression models were performed to explore heterogeneity. Ninetyone studies were included reporting 6473 IH. The pooled proportions of IH for OS were 0.35 (95% CI 0.27–0.44) I2 0% in midline laparotomies and 0.02 (95% CI 0.00–0.07), I2 52% for off-midline. In case of LS the pooled proportion of IH for midline extraction sites were 0.10 (95% CI 0.07–0.16), I2 58% and 0.04 (95% CI 0.03–0.06), I2 86% in case of off-midline. In Port-site IH was 0.02 (95% CI 0.01–0.04), I2 82%, and for single incision surgery (SILS) of 0.06—95% CI 0.02–0.15, I2 81%. In case of stoma reversal sites was 0.20 (95% CI 0.16–0.24). Midline laparotomies and stoma reversal sites are at high risk for IH and should be considered in research of preventive strategies of closure. After laparoscopic approach IH happens mainly by extraction sites incisions specially midline and also represent an important area of analysis.

In spite of the remarkable spread of the techniques in the last 10 years, are there still some problems related to the laparoscopic approach of malignant lesions of the colon: does it increase the risk of metastasis spread? which are the real advantages for the patient? does it increase the costs and are the benefits comparable? The authors present their experience on the resection of the sigmoid by laparoscopic approach. METHODS From September 1998 to August 2002, in the General Surgery Unit and Center of Laparoscopic Surgery of the Monaldi Hospital in Naples, 193 laparoscopic resections of the colon-rectum have been performed, which of 101 were resections of the sigmoid for benign and malignant pathologies. The patients were 54 males and 47 females, with an age range between 34 and 86 years. RESULTS The average operating time has been of 130 minutes (range 80-210). The average...

Recommendations have been published to manage patients needing surgery during the COVID-19 pandemic. This survey, under the aegis of the Italian Society of Endoscopic Surgery, aims to analyze how Italian surgeons have changed their practice during the pandemic. Methods The authors designed an online survey that was circulated for completion to the Italian departments of general surgery registered in the Italian Ministry of Health database in December 2020. Questions were divided into three sections: hospital organization, screening policies, and safety profile of the surgical operation. The investigation periods were divided into the Italian pandemic phases I (March–May 2020), II (June–September 2020), and III (October–December 2020). Results Of 447 invited departments, 226 answered the survey. Most hospitals were treating both COVID-19-positive and -negative pati...

This article reports on the European Hernia Society (EHS) Clinical Practice Guideline for RD. Method The Guideline group consisted of eight surgeons. The Grading of Recommendation, Assessment, Development and Evaluation (GRADE) approach and the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument were used. A systematic literature search was done in November 2018 and updated in November 2019 and October 2020. Nine Key Questions (KQs) were formulated. Results Literature reporting on the definition, classification, symptoms, outcomes and treatments was limited in quality, leading to weak recommendations for the majority of the KQs. The main recommendation is to define RD as a separation between rectus muscles wider than 2 cm. A new classification system is suggested based on the width...

This growing experience has also resulted in more reports of postoperative complications from the minimally invasive approach to primary colorectal resection. Small bowel obstruction from internal hernias and pre-sacral adhesions is an uncommon but not negligible complication. However, there is little literature specific to this topic with recommendations for different methods to prevent it. We report our original technique of closing the mesenteric defect and covering the pre-sacral fascia by using fibrin sealant to prevent this complication. Methods From January 2005 to December 2014, a total of 1079 patients underwent elective laparoscopic left colorectal resection (left hemicolectomy or anterior rectal resection) in our department. In the first 298 procedures, the mesenteric defect was left open, while in the following 781 procedures, it was closed using fibrin sealant with the aim of preventing postoperative small bowel obstruction. Results Among the first 298 patients, three (1%) required reoperation for small bowel obstruction due to internal hernia (0.33%) or critical pre-sacral adhesions (0.66%). These complications did not occur in the subsequent series in which all 781 patients were treated with fibrin sealant prophylactic closure of the mesenteric defect. Conclusion In our experience, fibrin sealant closure of the mesenteric defect has demonstrated to be safe and effective in preventing postoperative small bowel obstruction that remains a complication both in open and in laparoscopic colorectal surgeries.

The aim of our multicenter study was to evaluate the operative and patient-reported outcomes using a modified posterior component separation in patients who present with the combination of midline and lateral incisional hernia. Methods: We identified patients from a prospective, multicenter database who underwent operative repairs of a midline and lateral incisional hernia at 4 centers with minimum 2-year follow-up. Hernias were divided into a main hernia based on the larger size and associated abdominal wall hernias. Outcomes reported were short-and long-term complications, including recurrence, pain, and bulging. Quality of life was assessed with the European Registry for Abdominal Wall Hernias Quality of Life score. Results: Fifty-eight patients were identified. Almost 70% of patients presented with a midline defect as the main incisional hernia. The operative technique was a transversus abdominis release in 26 patients (45%), a modification of transversus abdominis release 27 (47%), a reverse transversus abdominis release in 3 (5%), and a primary, lateral retromuscular preperitoneal approach in 2 (3%). Surgical site occurrences occurred in 22 patients (38%), with only 8 patients (14%) requiring procedural intervention. During a mean follow-up of 30.1 ± 14.4 months, 2 (3%) cases of recurrence were diagnosed and required reoperation. There were also 4 (7%) patients with asymptomatic but visible bulging. The European Registry for Abdominal Wall Hernias Quality of Life score showed a statistically significant decrease in the 3 domains (pain, restriction, and cosmetic) in the postoperative score compared with the preoperative score. Conclusion: The different techniques of posterior component separation in the treatment of combined midline and lateral incisional hernia show acceptable results, despite the associated high complexity. Patient-reported outcomes after measurement of the European Registry for Abdominal Wall Hernias Quality of Life score demonstrated a clinically important improvement in quality of life and pain.

The most important and relevant argument for this proposal and statement is the growing acceptance of the increasing complexity of abdominal wall surgery due to newer techniques, more challenging cases and the required ‘tailored’ approach to such surgery. There is now also an increasing public awareness with social media, whereby optimal treatment results are demanded by patients. However, to date the complexity of abdominal wall surgery has not been properly or adequately defined in the current literature. Methods A systematic search of the available literature was performed in May 2019 using Medline, PubMed, Scopus, Embase, Springer Link, and the Cochrane Library, with 75 publications identified as relevant. In addition, an analysis of data from the Herniamed Hernia R...
