Article Synopsis
  • This study compares two surgical methods, Hartmann's procedure (HP) and resection with primary anastomosis (RPA), for treating acute left-sided colonic emergencies among 1215 patients from 204 centers globally.
  • Results showed that while HP was the more common treatment (57.3%), RPA was favored for younger patients with fewer health issues and those needing surgery sooner.
  • The study concluded that although HP is still widely used, RPA might be the better option, emphasizing the importance of patient characteristics and surgeon experience in determining treatment choice.

Article Synopsis
  • * Both OP and WS had similar rates of COVID-19 incidence, but OP experienced milder symptoms and clinical courses; however, these differences were not statistically significant.
  • * Patients with BS who contracted COVID-19 had better weight loss outcomes and a higher occurrence of gastric-bypass procedures, indicating that follow-up for these patients is essential as COVID-19 may influence BS results.

Introduction: Bariatric surgery is a safe and effective treatment for obesity, although in super-obese patients (BMI ≥50 kg/m2) it can become challenging for anatomical and anesthesiologic issues. Several bridging therapies have been proposed to increase preoperative weight loss and decrease perioperative morbidity and mortality. The aim of this study was to compare the efficacy and safety of different two-stage approaches in super-obese patients: laparoscopic sleeve gastrectomy (LSG) following preoperative liraglutide therapy versus LSG with preoperative intragastric balloon (IGB) during a 1-year follow-up.

Introduction: The management of chole-choledocholithiasis remains a matter of debate to preserve minimal invasive management and different options have been proposed, with single- or two-stage approaches. Two techniques of single-stage approach are intraoperative ERCP and laparoscopic rendezvous, which have the great advantage of reducing the length of hospital stay with increased patient compliance. This retrospective study aims to evaluate and compare the efficacy and safety of intraoperative ERCP and rendezvous technique for more than 15 years.

Background: One of the most controversial issues surrounding laparoscopic sleeve gastrectomy is the development of gastroesophageal reflux disease following surgery. The aim of the study was to evaluate the occurrence of gastroesophageal reflux disease after laparoscopic sleeve gastrectomy and to analyze patients' weight loss, comorbidities, and quality of life after surgery.

Methods: The clinical records of 52 patients submitted to laparoscopic sleeve gastrectomy between January and November 2018, with 3 years of follow-up, were retrospectively reviewed.

Little is known about the role of chronic gastritis on weight loss after laparoscopic sleeve gastrectomy (LSG). This study aims to investigate the relationship between histopathologic findings of gastric specimens, excess weight loss (% EWL), and excess BMI loss (% EBL) at 6 and 12 months follow up after LSG. We retrospectively reviewed the clinical records of 95 patients who had undergone LSG between January 2017 and December 2019.

Single or double prolapsed pile instead of full muco-hemorrhoidal prolapse is a common finding in patients with symptomatic III or IV degree hemorrhoids. For this selected group of patients, relief of symptoms could be achieved by managing the single/double prolapsed piles instead of performing traditional hemorrhoidectomy. The aim of this single-center study was to evaluate the safety and medium- and long-term effectiveness of an outpatient tailored Milligan-Morgan hemorrhoidectomy (MMH) performed under local anesthesia (LA).

BACKGROUND Hepatic portal venous gas (HPVG) associated with pneumatosis intestinalis (PI) can be indicative of several diseases, including inflammatory bowel disease (IBD), infective and obstructive gastrointestinal conditions, and also potentially life-threatening situations such as mesenteric ischemia. CASE REPORT A 60-year-old female patient came to our attention with evidence at computed tomography (CT) scan of gas in the portal vein and bowel walls with no sign of ischemia. General tenderness of the abdomen with absence of bowel sounds was detected at the physical examination.

Background: Postoperative bleeding is a common complication after endoscopic polypectomy, particularly after endoscopic mucosal resection (EMR) of large non-pedunculated polyps, despite prophylactic clipping can reduce its occurrence. Cyanoacrylate glue has recently been proposed as a useful tool in reducing bleeding in surgery because of its adhesive and haemostatic properties. The aim of this study is to evaluate the usefulness of endoscopic application of a modified cyanoacrylate glue in the prevention of early or delayed post EMR bleeding.

BACKGROUND Laparoscopic sleeve gastrectomy (LSG) has become the most common surgical procedure performed in bariatric surgery. Large hiatal hernias and Barrett's esophagus are the only contraindications recognized among experts. However, some studies have suggested that LSG may exacerbated gastroesophageal reflux disease (GERD) symptoms or induce postoperative GERD de novo.

BACKGROUND Gastrointestinal stomal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, and the stomach is the most commonly involved organ. Complete surgical resection with negative margins is the primary and only potentially curative treatment. Surgeon experience with minimally invasive gastric resections in addition to the tumor size and site has to be considered in the choice of laparoscopic or open surgical approach in order to remove the lesion.
