BACKGROUND: Surgery for remnant gastric cancer (RGC) frequently fails to obtain the >15 lymph nodes necessary for tumor-node-metastasis (TNM) staging. We aimed to evaluate the utility of the recently developed tumor-ratio-metastasis (TRM) staging system. We also examined the pattern of lymph node metastasis and the role of prophylactic splenectomy in RGC. METHODS: Between May 2003 and December 2012, data from 170 patients who underwent surgery for RGC were retrospectively analyzed...

Bariatric surgery is highly successful in improving health compared to conventional dietary treatments. It has been suggested that the gut microbiota is a relevant factor in weight loss after bariatric surgery. Considering that bariatric procedures cause different rearrangements of the digestive tract, they probably have different effects on the gut microbiota. In this study, we compared the impact of medical treatment, sleeve gastrectomy and Roux-en-Y gastric bypass on the gut microbiota from obese subjects...

BACKGROUND: Leakage from the staple line is the most serious complication encountered after sleeve gastrectomy, occurring in 2.4% of surgeries. The use of inappropriately sized staplers, because of variability in stomach wall thickness, is a major cause of leakage. OBJECTIVES: To measure stomach wall thickness across different stomach zones to identify variables correlating with thickness. METHODS: The study comprised 100 patients (52 females)...

Primary bariatric surgery has been proven to be effective in weight loss and improvement of weight-related metabolic co-morbidities. However, a small proportion of patients after bariatric surgery either have persistent hyperglycemia or relapse after initial remission of their metabolic disease. Revisional bariatric surgery has been evaluated extensively for weight recidivism and postoperative complications. However, there has not been any high-level evidence validating the utility of revisional bariatric surgery on recurrent metabolic diseases, especially diabetes...

To truly reduce the rates of chronic kidney disease, a root cause of kidney damage, obesity, must be targeted. Weight loss is often unsustainable because imbalances in satiety regulators are frequently not addressed to ensure maintenance of weight loss. In a recent study, gastric bypass surgery rebalanced satiety signals through resensitization of the gut-brain axis in obesity. This research may lead to noninvasive strategies to reduce obesity and obesity-related kidney disease.

BACKGROUND: Although foreign bodies (FBs) typically pass spontaneously and uneventfully through the digestive tract, a subset of such bodies may become trapped, eventually leading to significant injury. In particular, the ingestion of magnetic materials can cause serious morbidity due to proximate attraction through the intestinal wall. CASE PRESENTATION: We recently treated three pediatric patients who had ingested several magnetic foreign materials. None of these patients exhibited any clinical symptoms or signs suggestive of surgical abdomen...

BACKGROUND: Feeding jejunostomy has increasingly become a standard adjunctive procedure during major esophago-gastric resections. They provide nutritional support during the post-operative period as required. However, significant early complications have been reported, most notably small bowel necrosis. Literature reports have been restricted to case reports or series. This study aims to determine the frequency of this complication in a cohort of patients undergoing esophago-gastric resection, and identify any difference in the risk of this complication between patients undergoing esophagectomy and gastrectomy...

Optical coherence tomography (OCT) is a real-time, cross-sectional optical imaging technology. It is analogous to ultrasonography, except that OCT uses light waves instead of sound waves, and can provide three-dimensional morphological images of living tissues with a micrometer resolution. Through the use of endoscopes, needles, catheters and laparoscopes, OCT has demonstrated tremendous imaging potential in tumor surgery. The current studies suggest that OCT has potential for clinical applications in the following fields of gastrointestinal tumor surgery: (1) Early tumor detection and diagnosis: OCT can distinguish differences between polyp tissue, normal tissue and malignant tissue...

Obesity increases the risks of metabolic disorders including type 2 diabetes mellitus (T2DM). Bariatric surgery is the most successful therapeutic option that causes sustained weight loss and improvements in obesity comorbidities. Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG) are two of the most frequently performed bariatric surgeries. Despite their different anatomical rearrangement, they have remarkably similar success in both weight loss and T2DM remission. Interestingly, they also both cause a wide range of endocrine changes...

BACKGROUND: Although magnifying endoscopy with narrow-band imaging (ME-NBI) can help identify the horizontal margin (HM) of early gastric cancer (EGC), little is known about the factors that can clarify the HM by using ME-NBI. We aimed to characterize the pathological features of lesions in which the HM was identified using ME-NBI. METHODS: The HMs of 639 differentiated-type EGCs treated with endoscopic submucosal dissection or surgery were analyzed using conventional endoscopy and ME-NBI...
