This report aims to review current data on single-incision (single-port) laparoscopic surgery (SILS) for bariatric surgery. A comprehensive research of Pubmed database and Cochrane library on SILS ...bariatric surgery was conducted. Twenty-eight articles met inclusion criteria (3611 patients). Intraoperative and clinical outcomes for SILS sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and adjustable gastric banding (AGB) seem comparable to conventional laparoscopy. SILS for SG was safe and feasible with good outcomes. The same stands for RYGB but more studies are necessary for safe conclusions, while additional trocars are necessary to perform the procedure. AGB is feasible and safe by SILS but the declining number of annual procedures will probably limit the use of SILS. Major studies are unavailable for SILS and other bariatric procedures.

Purpose
Laparoscopic sleeve gastrectomy (LSG) is the most frequently performed bariatric procedure worldwide. Postoperative staple-line leak and intraabdominal hemorrhage can increase associated ...morbidity and mortality. The value of routine early computed tomography (CT) scanner examination in the early diagnosis of complications in high-risk severely obese patients undergoing LSG is studied.
Methods
This was a prospective, non-randomized study including all patients undergoing LSG in our department from 2014 to 2020. Patients presenting at least one potential risk factor for postoperative gastric leak and bleeding (as defined by the current literature) were included. Primary endpoint was the efficacy of postoperative day (POD) 2 CT-scanner examination in diagnosing these complications.
Results
One thousand fifty-one high-risk patients were included. Median age was 44 years. Early postoperative surgical complications occurred in 48 patients (4.5%): 25 (2.3%) intraabdominal hemorrhage and 23 (2.2%) staple-line leak. Early CT-scanner detected intraabdominal bleeding or hematoma in 22/25 patients, with 95.6% sensitivity (Youden’s index = 0.95), while specificity was 100%, positive predictive value (PPV) 100%, and negative predictive value (NPV) 99.9%. Sensitivity of early postoperative CT-scanner was 43.4% (10/23 patients; Youden’s index = 0.43) for staple-line leak detection, with specificity of 100%, PPV 100%, and NPV 98.7%.
Conclusion
POD 2 CT-scanner in high-risk severely obese patients undergoing LSG is an excellent tool for early diagnosis of intraabdominal hemorrhage, but sensitivity remains low for staple-line leak detection. Close postoperative clinical follow-up of these patients is essential and any suspicion of postoperative surgical complication should motivate the performance of a CT-scanner.

Background
Submucosal tumors (SMTs) of the gastrointestinal tract are a rare pathological entity comprising a wide variety of neoplastic and non-neoplastic lesions. Even if most SMTs are benign ...tumors (e.g., leiomyomas), a smaller portion may have a malignant potential (e.g., gastrointestinal stromal tumor (GIST)). Preoperative diagnosis of SMT in bariatric patients may arise challenging clinical dilemmas. Long-term surveillance may be difficult after bariatric surgery. Moreover, according to SMT location, its presence may interfere with planned surgery. Submucosal tunneling endoscopic resection (STER) has emerged as an effective approach for minimally invasive en bloc excision of SMTs. This is the first case series of STER for SMTs before bariatric surgery.
Methods
Seven female patients underwent STER for removal of SMTs before bariatric surgery. All lesions were incidentally diagnosed at preoperative endoscopy. STER procedural steps comprised mucosal incision, submucosal tunneling, lesion enucleation, and closure of mucosal defect.
Results
En bloc removal of SMT was achieved in all cases. Mean procedural time was of 45 min (SD 18.6). No adverse event occurred. Mean size of the lesions was 20.6 mm (SD 5.8). Histological diagnoses were 5 leyomiomas, 1 lipoma, and 1 low grade GIST. Bariatric procedure was performed after a mean period of 4.1 months (SD 1.6) from endoscopic resection.
Conclusion
STER is a safe and effective treatment for the management of SMT even in bariatric patients awaiting surgery. Preoperative endoscopic resection of SMTs has the advantages of reducing the need for surveillance and removing lesions that could interfere with planned surgery. STER did not altered accomplishment of bariatric procedures.

Introduction
Despite advances in treating gastric staple line leaks after bariatric surgical procedures, chronic leaks have been reported. Failure of their treatment frequently leads to radical ...surgery. We aimed to describe a strategy for preventing occurrence of chronic gastric leaks after complicated sleeve gastrectomy in patients necessitating relaparoscopy and external drainage as a first step of gastric leak management.
Methods
Data from 14 consecutive patients admitted for gastric leak after laparoscopic sleeve gastrectomy were prospectively collected and retrospectively analyzed. Patients included underwent relaparoscopy and external drainage as first step of management.
Results
Median time to gastric leak detection was 4 days. Emergency relaparoscopy allowed peritoneal lavage and external drainage placement next to the leak. Median time between surgery and endoscopic internal drainage (EID) was 4 days. Progressive external drainage mobilization started after 2 days. Control endoscopy was performed every 4 weeks until healing. A median interval of 112 days was necessary before healing in 13 patients. Thirteen patients (92.8%) had no gastric leak recurrence at 1 year. In one patient, EID was considerably delayed and external drainage mobilization prolonged, leading to chronic gastric leak and total gastrectomy after 18 months.
Conclusion
This study reports for the first time a well-standardized protocol of early EID after relaparoscopy coupled to rapid external drainage removal for effectively treating complicated cases of sleeve gastrectomy
.
Bariatric surgeons should be aware of such therapeutic strategies and include them in their arsenal against postoperative gastric staple line leaks in severely obese patients.

Surgical strategies are being adapted to face the COVID-19 pandemic. Recommendations on the management of acute appendicitis have been based on expert opinion, but very little evidence is available. ...This study addressed that dearth with a snapshot of worldwide approaches to appendicitis.
The Association of Italian Surgeons in Europe designed an online survey to assess the current attitude of surgeons globally regarding the management of patients with acute appendicitis during the pandemic. Questions were divided into baseline information, hospital organization and screening, personal protective equipment, management and surgical approach, and patient presentation before versus during the pandemic.
Of 744 answers, 709 (from 66 countries) were complete and were included in the analysis. Most hospitals were treating both patients with and those without COVID. There was variation in screening indications and modality used, with chest X-ray plus molecular testing (PCR) being the commonest (19·8 per cent). Conservative management of complicated and uncomplicated appendicitis was used by 6·6 and 2·4 per cent respectively before, but 23·7 and 5·3 per cent, during the pandemic (both P < 0·001). One-third changed their approach from laparoscopic to open surgery owing to the popular (but evidence-lacking) advice from expert groups during the initial phase of the pandemic. No agreement on how to filter surgical smoke plume during laparoscopy was identified. There was an overall reduction in the number of patients admitted with appendicitis and one-third felt that patients who did present had more severe appendicitis than they usually observe.
Conservative management of mild appendicitis has been possible during the pandemic. The fact that some surgeons switched to open appendicectomy may reflect the poor guidelines that emanated in the early phase of SARS-CoV-2.

Nonoperative treatment can be attempted for uncomplicated adhesive small bowel obstruction (ASBO), but carries a risk of delayed surgery. Highlighting initial parameters predicting risk of failure of ...nonoperative management would be of great interest.
Patients initially managed conservatively for uncomplicated ASBO were retrospectively analyzed. Univariate and multivariate analysis were performed to identify predictive failure's factors. Based on the risk factors, a score was created and then prospectively validated in a different patients' population.
Among 171 patients included, 98 (57.3%) were successfully managed conservatively. In a multivariate analysis, three independent nonoperative management failure's factors were identified: Charlson Index ≥4 (P = 0.016), distal obstruction (P = 0.009), and maximum small bowel diameter over vertical abdominal diameter ratio >0.34 (P = 0.023). A score of two or three was associated with a risk of surgery of 51.4% or 70.3% in the retrospective analysis and 62.2% or 75% in the validation cohort, respectively.
This clinical-radiological score may help guide surgical decision-making in uncomplicated ASBO. A high score (≥2) was predictive of failure of nonoperative management. This tool could assist surgeons to determine who would benefit from early surgery.

Background
SPSG carries a risk of incisional hernia, particularly in patients with high body mass index. Prophylactic mesh placement with either permanent or absorbable mesh could decrease the ...occurrence of incisional hernia, with uncertainty on other postoperative parietal complications.
Methods
This is a non-randomized monocentric single-blinded prospective study. High-risk patients (body mass index ≥ 45 kg/m
2
) underwent either 3 strategies of parietal closure (suture with or without permanent or absorbable mesh) during SPSG. The primary outcome was the occurrence of radiologically defined incisional hernia during the first postoperative year. Secondary outcomes included surgical site infection rates and postoperative pain.
Results
Between November 2018 and November 2019, 255 patients were included (85 in each group). All patients reached one-year postoperative follow-up. Significantly more incisional hernias were observed in the no mesh group in comparison with permanent and absorbable mesh groups, respectively (20% vs. 7.1% vs. 5.1%,
P
= 0.005). No difference was observed in mesh groups. No difference was observed regarding other parietal complications. One patient in the absorbable mesh group presented a superficial surgical site infection and required surgical drainage without mesh removal and one patient in the permanent mesh group presented a parietal hematoma and required surgical drainage with mesh removal. Twenty-six (92.8%) asymptomatic patients presented incisional hernia discovered on the one-year CT-scan.
Conclusions
Prophylactic mesh placement during SPSG decreases the occurrence of postoperative incisional hernia. Routine permanent mesh placement could be proposed in high-risk patients.

Purpose
We report an unusual case of endometriosis of the appendix with simultaneous invasion of the sigmoid colon.
Methods
Clinical, radiological, surgical, and histological data of the patient were ...reviewed, as well as the current literature on gastrointestinal endometriosis.
Results
A 41-year-old woman presented to the emergency department of our hospital with acute right lower quadrant pain, pronounced tenderness elevated white blood cell count, and increased C-reactive protein. Abdominal CT scan suggested a mucocele of the appendix. The patient was first treated with antibiotics, followed by en bloc resection of the appendix and of the sigmoid colon 2 months later. Histological examination revealed an endometriotic nodule of the appendix filling the appendiceal lumen and resulting in a mucocele which invaded the sigmoid colon wall.
Conclusions
The diagnosis of gastrointestinal endometriosis can be challenging due to the variety of symptoms it can produce. Although extremely rare, a concomitant double gastrointestinal location of endometriosis may be possible and should be considered in women of reproductive age.
