Bariatric surgery, as the most effective approach to treating obesity at present, encompasses a wide array of procedures. However, due to the significant anatomical changes to the gastrointestinal tract caused by most of these procedures, they are associated with certain risks of complications. In the pursuit of minimizing trauma, bariatric surgeons have begun exploring new surgeries in addition to traditional procedures. Gastric plication surgeries encompass various procedures such as gastric fundoplication, gastric greater curvature plication, endoscopic sleeve gastroplasty, combined gastric fundoplication with gastric greater curvature plication, and combined gastric fundoplication with sleeve gastrectomy, among others. The efficacy and risks of complications associated with these procedures fall between those of medical therapy and sleeve gastrectomy. Gastric fundoplication, functioning as an anti-reflux procedure, can also be integrated into weight loss surgical interventions to effectively address obesity-related gastroesophageal reflux disease in obese patients. Both gastric greater curvature plication and endoscopic sleeve gastroplasty yield favorable weight loss outcomes. Beyond the impact of folding procedures on body mass, gastric plication surgeries can also be combined with other techniques. The combination of gastric fundoplication with sleeve gastrectomy or greater curvature plication can reduce body mass and mitigate reflux, while the combination of greater curvature plication with gastric bypass and similar procedures can further enhance weight loss and metabolic improvements.
作为目前治疗肥胖最有效的方法，减重手术术式众多，但由于大部分的术式引起胃肠道解剖的巨大改变，使得其存在一定的并发症风险。为了追求更小的创伤，减重外科医生在经典术式之外开始探索胃折叠手术。胃折叠手术包括胃底折叠术、胃大弯折叠术、内镜下胃成形术、胃底折叠术联合胃大弯折叠术、胃底折叠术联合袖状胃切除术等多种术式，其疗效和并发症的风险介于药物治疗和袖状胃切除手术之间。胃底折叠术作为一种抗反流的术式，也可参与到减重手术治疗中，有效改善肥胖患者和减重手术相关胃食管反流病。胃大弯折叠术和内镜下胃成形术均有很好的减重效果。除了折叠术式本身对体质量的影响，胃折叠术还能与其他的术式联合。胃底折叠术联合袖状胃切除和胃大弯折叠术，可降低体质量并减少反流；胃大弯折叠术联合胃旁路等术式，也可更加有效地降低体质量，改善代谢。.

Introduction: Reported results and techniques of laparoscopic sleeve gastrectomy (LSG) are variable. Our objective was to assess results of weight loss, complications, and reflux in a large consecutive series of LSG, describing technical detail which contributed to outcomes. Methods: Retrospective review of prospectively collected data of 500 consecutive patients undergoing LSG. Patient demographics, weight loss, complications, and functional outcomes were analyzed and operative technique described. Results: Five hundred patients underwent LSG over 3 years (2 revisional). Mean (range) preoperative body mass index was 40 kg/m2 (32-75 kg/m2). Mean follow-up and length of hospital stay were 12 months (1-36) and 7.2 days (5-12), respectively. All-cause 30-day readmission rate was 0.3%. Mean excess weight loss was 22.3% (1 month), 42.2% (3 month), 57.2% (6 month), and 73.1% (1 year). There was no mortality and intraoperative complications occurred in our 500 cases. Early surgical complications in 2 (0.2%) patients (postoperative bleeds). Gastro-oesophageal reflux symptoms decreased about 10%. Conclusion: With attention to detail, LSG can lead to good excess weight loss with minimal complications. Tenants to success include repair of hiatal laxity, generous width at angula incisura, and complete resection of posterior fundus.

Laparoscopic adjustable gastric banding (LAGB) is commonly used in the treatment of morbid obesity. However, with clinical application and long-term follow-up, the shortcomings of this procedure were also exposed, bringing about surgery-related complications include dysphagia, intragastric band migration, slippage, and gastric band erosion. Lower esophageal and gastric fistula is a rare but dangerous complication after LAGB. We describe a case of esophagogastric fistula occurring twelve years after a laparoscopic band procedure and its successful management in a multidisciplinary and staged manner, followed by a short review of the literature.

BACKGROUND: Laparoscopic banded sleeve gastrectomy (LBSG) has been compared to laparoscopic sleeve gastrectomy (LSG) in terms of anthropometric results and postoperative complications, which are controversial. This systematic review and meta-analysis aimed to compare the safety and efficacy of LBSG and LSG.
METHODS: We performed a systematic review with meta-analysis according to preferred reporting items for systematic review and meta-analysis 2020 and assessing the methodological quality of systematic review 2 guidelines. We included studies that systematically searched electronic databases and compared LBSG with LSG conducted until August 10, 2021.
RESULTS: The literature search yielded 8 comparative studies. Seven hundred forty-three patients were included: 352 in the LBSG group and 391 in the LSG group. LBSG group allowed greater anthropometric parameters (body mass index [BMI] after 1 year (mean difference [MD] = -3.18; 95% CI [-5.45, -0.92], P = .006), %EWL after 1 year (MD = 8.02; 95% CI [1.22, 14.81], P = .02), and %EWL after 3 years (MD = 10.60; 95% CI [5.60, 15.69], P < .001) and similar results with LSG group in terms of operative time (MD = 1.23; 95% CI [-4.71, 7.17], P = .69), food intolerance (OR = 1.72; 95% CI [0.84, 3.49], P = .14), postoperative vomiting (OR = 2.10; 95% CI [0.69, 6.35], P = .19), and De novo GERD (OR = 0.65; 95% CI [0.34, 1.26], P = .2). Nevertheless, major postoperative complications did not differ between the 2 groups.
CONCLUSIONS: This systematic review and meta-analysis comparing LBSG and LSG concluded that banding sleeve gastrectomy (SG) may ensure a lower BMI and %EWL after 1 year of follow-up, and a significant reduction in %EWL after 3 years of follow-up. There is no evidence to support LBSG in vomiting, de novo GERD, food intolerance, or operative time.

Obesity and its complications, such as type 2 diabetes, hypertension, hyperlipidemia, nonalcoholic fatty liver, are serious global public health problems. Endoscopic sleeve gastroplasty (ESG) can reduce the length and width of the stomach by simulating the anatomical structure of surgical sleeve gastrectomy to reduce the capacity of the stomach, and is safe and effective to reduce weight. ESG has the advantages of non- invasiveness, no gastrectomy, repeatability, simple operation, no incision scar, few complications, short hospital stay and quick postoperative recovery. As an intermediate means of medical treatment and surgery, ESG provides a new method for weight loss for obese patients who cannot tolerate or are unwilling to undergo surgery. Herein we trace the origin of ESG, analyze the unique advantages of ESG suture, explore the technical improvement in the development of ESG, and briefly describe the weight reduction effect of ESG and compare the curative effect of ESG with laparoscopic sleeve gastrectomy. ESG has undergone rapid development and maturity but also faces such challenges as the lack of established standard procedures, unclear weight reduction mechanism, and clarification of the indications for operation. Still, ESG is expected to become the mainstream technique for weight reduction.

BACKGROUND: One Anastomosis/Mini Gastric Bypass (OAGB-MGB) is rapidly gaining popularity and is now the third common bariatric procedure performed in the world. The aim of this review is to look at the role of this operation as a revisional bariatric surgery (RBS).
METHODS: Literature review was performed following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and the AMSTAR (Assessing the methodological quality of systematic reviews) guidelines. Total 17 studies were eligible.
RESULTS: This review reports cumulative results of 1075 revisional OAGB-MGB procedures. Primary procedures included gastric banding (LAGB), Sleeve gastrectomy (SG), vertical banded gastroplasty (VBG) and gastric plication. The mean age was 43.1 years and female to male ratio was 3.04: 1. The body mass index (BMI) at primary procedure was 47.05 kg/m2. The mean BMI at revisional surgery was 41.6 kg/m2 (range 28-70.8). The mean time between the primary and the secondary operation was 46.5 months (3-264). The mean follow-up was 2.44 years (6-60 months). The mean operative time was 119.3 min. The mean length of hospital stay was 4.01 days (2-28). The median limb length was 200 cm (range 150-250 cm). Leak rate was 1.54%. Marginal ulcer rate was 2.44%. Anemia rate was 1.9%. Mortality was 0.3%. The excess weight loss (%EWL) at 1 year and 2 years was 65.2% and 68.5% respectively.
CONCLUSIONS: We conclude that there is evidence to consider OAGB-MGB as a safe and effective choice for RBS. Randomised studies with long term follow-up are suggested for the future.
