Background: The role of robotic surgery for gastrointestinal stromal tumor (GIST) resection remains unclear. This systematic review and meta-analysis aimed to investigate the outcomes of robotic versus laparoscopic surgery in patients requiring surgery for gastric GISTs. Methods: MEDLINE, EMBASE, and the Cochrane databases were searched from inception to September 4, 2023. Two independent reviewers conducted a systematic review of the literature to select all types of analytic studies comparing robotic versus laparoscopic surgery for GISTs and reporting intraoperative, postoperative, and/or pathological outcomes. Results: Overall, 4 retrospective studies were selected, including a total of 264 patients, specifically 111 (42%) in the robotic and 153 (58%) in the laparoscopic group. Robotic surgery was associated with longer operating time (+42.46 min; 95% confidence interval [CI]: 9.34, 75.58; P=0.01; I2: 85%) and reduced use of mechanical staplers (odds ratio [OR]: 0.05; 95%CI: 0.02, 0.11; P<0.00001; I2: 92%;) compared with laparoscopy. Although nonsignificant, conversion to open surgery was less frequently reported for robotic surgery (2.7%) than laparoscopy (5.2%) (OR: 0.59; 95%CI: 0.17, 2.03; P=0.4; I2: 0%). No difference was found for postoperative and oncological outcomes. Conclusions: Robotic surgery for gastric GISTs provides similar intraoperative, postoperative, and pathological outcomes to laparoscopy, despite longer operative time. [ABSTRACT FROM AUTHOR]

Background: The Limberg flap reconstruction and the Karydakis flap reconstruction are the 2 most used off-midline closure techniques in pilonidal sinus surgery. The current evidence is inconclusive as to which is the optimal technique. The aim of this systematic review and meta-analysis was to compare differences in outcomes between these 2 flap-based techniques. Methods: We identified studies by a systematic literature search of the Embase, MEDLINE (PubMed), Cochrane Library and Google Scholar databases and studies selected as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Only randomized controlled trials (RCTs) that compared the Limberg flap (standard or modified) and the Karydakis flap were included in this review. Results: Operative time was shorter by 7 minutes in the Karydakis group than in the Limberg group (mean difference 7.00 min, 95% confidence interval [CI] 0.53 to 13.48). The seroma formation rate was significantly higher in the Karydakis cohort (odds ratio [OR] 0.36, 95% CI 0.24 to 0.56); however, after excluding studies with a high risk of bias, the sensitivity analysis showed no significant differences in seroma formation rate between the 2 techniques (OR 0.76, 95% CI 0.31 to 1.85). Other outcomes of interest showed no significant differences between the Limberg and Karydakis techniques. Conclusion: There were no significant differences between the Limberg and Karydakis techniques. Future RCTs with strict adherence to CONSORT guidelines will further elucidate the efficacy of these surgical procedures. Contexte: Les reconstructions a l'aide de lambeaux de Limberg et de Karydakis sont 2 des techniques de fermeture decalees de la ligne mediane les plus utilisees pour la chirurgie du sinus pilonidal. Les preuves actuelles ne permettent pas de conclure a la superiorite de l'une par rapport a l'autre. Le but de la presente revue systematique/meta-analyse etait de comparer les differences de resultats entre ces 2 techniques de lambeaux. Methodes: Nous avons recense des etudes au moyen d'une interrogation systematique des bases de donnees Embase, MEDLINE (PubMed), bibliotheque Cochrane et Google Scholar et les etudes selectionnees a l'aide de la liste de verification PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Seuls les essais randomises et controles (ERC) qui comparaient les lambeaux de Limberg (standard ou modifie) et de Karydakis ont ete inclus dans cette revue. Resultats: Les interventions ont dure 7 minutes de moins dans le groupe Karydakis que dans le groupe Limberg (difference moyenne 7,00 min, intervalle de confiance [IC] de 95% 0,53 a 13,48). Le taux de formation de seromes a ete significativement plus eleve dans la cohorte Karydakis (rapport ces cotes [RC] 0,36, IC de 95% 0,24 a 0,56); par contre, apres avoir exclu les etudes comportant un important risque de biais, l'analyse de sensibilite n'a montre aucune difference significative quant au taux de formation de seromes entre les 2 techniques (RC 0,76, IC de 95% 0,31 a 1,85). Les autres parametres d'interet n'ont montre aucune difference significative entre les techniques de Limberg et de Karydakis. Conclusion: On n'a note aucune difference significative entre les techniques de Limberg et de Karydakis. De prochains ERC strictement conformes aux lignes directrices CONSORT permettront de preciser davantage l'efficacite de ces interventions chirurgicales., The reported incidence rate of pilonidal disease is 25 per 100 000 people. (1) Initially, the pathogenesis was considered to be congenital. (2) Today, however, the theory that it is [...]

Primary segmental omental torsion (PSOT) is a very rare cause of acute abdominal pain, and it may often imitate the clinical picture of acute appendicitis. In instances of acute abdominal pain without anorexia, nausea, and vomiting, omental torsion should be included in the differential diagnosis. Any misdiagnosis may lead to major complications such as intraabdominal abscesses and adhesions. A 63-year-old overweight man with a body mass index (BMI) of 41 Kg/m² presented to the emergency department on a remote island with acute abdominal pain. His medical history included type 2 diabetes mellitus managed with insulin, essential hypertension, osteoarthritis, and no previous abdominal operations. He reported a sharp pain originating in the epigastrium and the right hypochondrium that started five days prior. Physical examination revealed rebound tenderness and guarding across the abdomen with a positive McBurney sign. However, the patient did not report vomiting and was not nauseous. Vital signs were as follows: blood pressure 116/56 mmHg, heart rate 98 beats/min, respiratory rate 19 breaths/min, and a temperature of 38.2 °C. Laboratory results showed a white blood cell count of 10.6, neutrophils of 8.11, C-reactive protein (CRP) 74 mg/l, haemoglobin11.6 g/dl, and hematocrit 36.9%. Due to the absence of a radiographer at the hospital during that period, no imaging investigations were conducted. Diagnostic laparoscopy demonstrated diffused hemoperitoneum and necrotic mass at the site of the hepatic flexure. Initially suspected to be an advanced colon cancer, the decision was made to proceed with open surgery. The necrotic segment of the omentum was found at the right superior point of attachment of the omentum to the hepatic flexure. Consequently, the necrotic segment of the omentum was resected. A thorough investigation of the abdominal cavity did not detect any other abnormalities or pathologies. The patient recovered uneventfully and was transferred to the surgical ward. Torsion of the omentum is a very rare cause of acute abdominal pain. This case highlights the necessity of considering PSOT in the differential diagnosis of acute abdominal pain, especially in cases where symptoms are suggestive of appendicitis but diagnostic findings are negative.

Background and Objectives: Robotic surgery has been widely adopted in general surgery worldwide but access to this technology is still limited to a few hospitals. With the recent introduction of new robotic platforms, several studies reported the feasibility of different surgical procedures. The aim of this systematic review is to highlight the current clinical practice with the new robotic platforms in general surgery. Materials and Methods: A grey literature search was performed on the Internet to identify the available robotic systems. A PRISMA compliant systematic review was conducted for all English articles up to 10 February 2023 searching the following databases: MEDLINE, EMBASE, and Cochrane Library. Clinical outcomes, training process, operating surgeon background, cost-analysis, and specific registries were evaluated. Results: A total of 103 studies were included for qualitative synthesis after the full-text screening. Of the fifteen robotic platforms identified, only seven were adopted in a clinical environment. Out of 4053 patients, 2819 were operated on with a new robotic device. Hepatopancreatobiliary surgery specialty performed the majority of procedures, and the most performed procedure was cholecystectomy. Globally, 109 emergency surgeries were reported. Concerning the training process, only 45 papers reported the background of the operating surgeon, and only 28 papers described the training process on the surgical platform. Only one cost-analysis compared a new robot to the existing reference. Two manufacturers promoted a specific registry to collect clinical outcomes. Conclusions: This systematic review highlights the feasibility of most surgical procedures in general surgery using the new robotic platforms. Adoption of these new devices in general surgery is constantly growing with the extension of regulatory approvals. Standardization of the training process and the assessment of skills' transferability is still lacking. Further studies are required to better understand the real clinical and economical benefit.
