Introduction: Postoperative gastroesophageal reflux disease (GERD) can be a consequence of laparoscopic sleeve gastrectomy (LSG). Intrathoracic sleeve migration (ITSM) is a factor contributing to its development. This study aimed to investigate whether the occurrence of ITSM can be prevented by applying a polyglycolic acid (PGA) sheet around the His angle.

Piriform fossa and/or esophageal injuries caused by calibration tubes are relatively rare and remain unelucidated. Herein, we report the case of a 36-year-old woman with morbid obesity, sleep apnea, and menstrual abnormalities who was scheduled to undergo laparoscopic sleeve gastrectomy (LSG). We inserted a 36-Fr Nelaton catheter made of natural rubber as a calibration tube during the surgery.

The number of laparoscopic sleeve gastrectomies (LSGs) performed in patients with obesity who are eligible for bariatric and metabolic surgery is currently much lower in Japan than in other countries. Considering the large number of potential patients with obesity and type 2 diabetes and the unique Japanese national health insurance system that guarantees fair healthcare delivery, there is room to increase the number of LSGs in Japan in the near future. However, strict health insurance regulations may limit access to mandatory devices needed to treat postoperative complications, such as staple line leakage, which can cause severe morbidity and even mortality.

Article Synopsis
  • Vertical sleeve gastrectomy (VSG) is a highly effective procedure for long-term weight loss and type 2 diabetes remission, with the study investigating the role of the metabolic hormone LEAP2 as a potential predictor for these outcomes.
  • A retrospective analysis of 39 Japanese patients assessed serum levels of LEAP2 and other parameters before and after VSG, revealing that higher preoperative LEAP2 levels correlated with better weight loss and diabetes remission predictions.
  • The findings suggest that preoperative serum LEAP2 concentrations could serve as a valuable indicator for anticipating patient outcomes related to weight loss and type 2 diabetes after undergoing VSG.

Background: Owing to their difficulty following clinical advice for procedural safety and ideal surgical outcomes, bariatric and metabolic surgery (BMS) for patients with disorders of intellectual development (DID) is concerning. Studies reporting the feasibility of BMS for this population remain scarce. This study aims to clarify the feasibility of laparoscopic sleeve gastrectomy (LSG) for patients with clinically severe obesity and DID.

Article Synopsis
  • - Primary cancer of the appendix, particularly signet-ring cell carcinoma, is rare and often undiagnosed until surgery, with symptoms including abdominal pain and changes in bowel habits.
  • - A case involved a 48-year-old woman who experienced chronic abdominal issues, leading to imaging that revealed a significant appendiceal tumor.
  • - Following laparoscopic surgery and adjuvant chemotherapy, the patient had a successful outcome with no recurrence over 23 months, highlighting the importance of identifying such cancers early.

Introduction: Bariatric surgery (BS) has beneficial effects on body weight and type 2 diabetes. However, 44-52%, 20-40%, and 19-25% of patients with type 2 diabetes who undergo sleeve gastrectomy, sleeve gastrectomy with duodenal-jejunal bypass, and Roux-en-Y gastric bypass, respectively, show insufficient improvement 1 year after BS. It is thus important to predict the improvement in type 2 diabetes before BS.

Introduction: We previously reported that preoperative serum insulin-like growth factor-1 (IGF-1) is a predictor of total weight loss percentage (%TWL) after laparoscopic sleeve gastrectomy (LSG). IGF-1 may suppress muscle loss after surgery. IGF-1 almost accurately reflects the growth hormone (GH) secretion status, and GH has lipolytic effects.

Introduction: Laparoscopic sleeve gastrectomy (LSG) significantly increases high-density lipoprotein cholesterol (HDL-C) and lipoprotein lipase (LPL) in pre-heparin serum (pre-heparin LPL levels). LPL is a regulator of serum triglyceride (TG) and HDL-C production; this may be the mechanism for HDL-C increase after LSG. This study aimed to elucidate the mechanism of increase in HDL-C levels by examining the relationship between changes in serum HDL-C levels and LPL after LSG.

Objective: Bariatric surgery (BS) improves glycemic control in type 2 diabetes; however, some patients show insufficient improvement. Understanding the pathophysiology of type 2 diabetes in obese patients can facilitate appropriate treatment for type 2 diabetes after BS. The homeostatic model assessment (HOMA) 2 enables the calculation of the values from C-peptide data and evaluation of insulin users.

Background: An increase in gastroesophageal reflux disease (GERD) after laparoscopic sleeve gastrectomy (LSG) has been reported, and concomitant hiatal hernia repair (HHR) during LSG is expected to reduce the incidence of post-LSG GERD. In HHR, the hepatic branch of the vagus nerve is anatomically transected. Recent experimental animal models suggest that vagotomy may affect glycemic control and weight loss through a neuroendocrine response.

Article Synopsis
  • Bariatric and metabolic surgeries (BMS) were introduced in Japan after they gained traction in Taiwan, but their adoption has been slow despite a high number of eligible patients with obesity and diabetes.
  • The Japanese national health insurance system, while promoting equitable healthcare, may actually hinder the growth and integration of BMS into treatment plans.
  • This article reviews the current status of BMS in Japan and explores key challenges such as insurance policies, surgical guidelines, training, original research, and the establishment of a national registry.

Background: Bariatric surgery is being recognized increasingly as an effective treatment for obesity and related comorbidities. In Japan, the cost of laparoscopic sleeve gastrectomy (LSG) is covered by the national health insurance for adults with a body mass index (BMI) ≥ 35 kg/m and specific comorbidities (type 2 diabetes mellitus (T2DM), hypertension (HT), dyslipidemia (DL), and obstructive sleep apnea syndrome (OSAS)). However, only 0.

Gastric leakage and stricture are challenging complications of sleeve gastrectomy (SG). Failure of endoscopic intervention necessitates revision surgery. We describe two cases in which proximal gastrectomy with double tract reconstruction (PG with DTR) was performed in patients with chronic gastric fistula and twisted gastric tube after SG.
