Importance: The long-term safety of laparoscopic distal gastrectomy for locally advanced gastric cancer (AGC) remains uncertain given the lack of 5-year follow-up results. Objective: To compare the 5-year follow-up results in patients with clinically AGC enrolled in the Korean Laparoendoscopic Gastrointestinal Surgery Study (KLASS)-02 randomized clinical trial who underwent laparoscopic or open distal gastrectomy. Design, Setting, and Participants: The KLASS-02, a multicenter randomized clinical

NIR imaging may provide additional node detection during laparoscopic LN dissection for gastric cancer, especially in the infra-pyloric area.

BACKGROUND: Anastomotic leakage is a severe complication after gastric cancer surgery. Inadequate blood supply is regarded as an important risk factor. The aim of the study was to evaluate the feasibility and usefulness of intraoperative assessment of anastomotic vascular perfusion in gastric cancer surgery using near-infrared (NIR) camera imaging with indocyanine green (ICG)-enhanced fluorescence technique. MATERIALS AND METHODS: From March 2015 to 2016, 30 patients undergoing laparoscopic gast

Compared to TG, PG showed an advantage in terms of postoperative morbidity and nutrition, and there was a comparable prognosis between the two procedures. Preserving the intra-abdominal esophagus may lower the incidence of reflux esophagitis associated with PG.

The enhanced recovery after surgery (ERAS) program is now widely applied in bariatric surgeries and other surgical procedures. The ERAS program in bariatric surgery consists of various components similar to that in colorectal surgery or other procedures. The major concept of the ERAS protocol relies on a multidisciplinary and multimodal approach to resolve various problems after surgical treatment. The key principles of the ERAS program in bariatric surgery include patient education, opioid-spar

Laparoscopic gastrectomy is evolving. With the increasing expertise and experience of oncologic surgeons in the minimally invasive surgery for gastric cancer, the indication for laparoscopic gastrectomy is expanding to advanced cases. Many studies have demonstrated the benefits of minimally invasive surgery, including reduced risk of surgery-related injury, reduced blood loss, less pain, and earlier recovery. In order to establish concrete evidence for the suitability of minimal invasive surgery

PURPOSE: The purpose was to evaluate outcomes according to different operative strategies of type A esophageal atresia (EA). METHODS: All patients who underwent surgery for type A EA between 1980 and 2011 were included. Patients were divided into 2 groups: E-E group included patients who received esophageal end-to-end anastomosis, whereas E-G group included patients who received esophago-gastric tube anastomosis. RESULTS: Twenty-two patients were included. The median gestational age was 37.5 wee

In this study, 42.3% (n = 55) of total patients developed newly developed GERD, and 7.7% (n = 10) had LA grade C or D esophagitis.

BACKGROUND: To examine the effect and mechanism of Roux-en-Y gastric bypass (RYGB) on the improvement of diabetes according to the length of anastomosis and the gastric pouch volume in an animal model. METHODS: Glucose intolerance was induced with a high-fat diet for 3 months in Sprague-Dawley rats. The animals were subjected to conventional RYGB (cRYGB; 5% gastric pouch with 15-cm Roux limb, 40-cm biliopancreatic limb; n = 9), short-limb RYGB (sRYGB; 5%, 8, 4 cm; n = 9), fundus-sparing RYGB (fR

Obesity represents a major global health challenge, requiring interventions that are both effective and economically sustainable. This review examines the cost-effectiveness of commonly discussed treatment options: glucagon-like peptide-1 receptor agonists (GLP-1 RAs), endoscopic sleeve gastroplasty (ESG), and metabolic/bariatric surgery (MBS). We synthesized evidence from published clinical studies and economic analyses, comparing incremental cost-effectiveness ratios (ICERs) and cost per quali
