A new type of athlete is appearing in the offices of sports dietitians: formerly obese people who have undergone gastric bypass surgery and now aspire to be marathoners, triathletes, and other types of endurance athletes. The standard nutrition advice offered to bypass patients is contrary to the standard sports advice given to athletes. Bypass athletes need to limit carbohydrates, fluids, and ...

A 61-year-old man was referred to our hospital to treat extrahepatic portal venous obstruction. Endoscopic injection sclerotherapy (EIS) was performed for the esophageal varices; however, the patient returned with massive hematemesis from gastric varices 6 months after treatment. Although the varices were treated with EIS, gastric devascularization and splenectomy concomitant with shunt surgery...

The type 2 diabetes mellitus (T2DM) is one of the most serious diseases that threaten public health. Modified gastric bypass surgery has been applied to the treatment of T2DM patients in the 1990s, but the therapeutic mechanism to this function is still unclear. The aim of this study was to further clarify the effect and the mechanism of modified gastric bypass surgery on glucose metabolism in ...

Gastropleural fistula after bariatric surgery is extremely rare and has been reported in a very small number of patients post sleeve gastrectomy and gastric bypass. CASE PRESENTATION A 37-year-old lady prese...

Case Description: The patient’s clinical presentation was intermittent biliary-type pain. On admission, no remarkable physical findings were observed, but a dilated common...

The Roux-en-Y gastric bypass is one of the most common procedures currently performed for surgical treatment of patients with severe obesity. Gastric cancer after bariatric surgery is not common, with most of them arising in the excluded stomach. Gastric mixed adenoneuroendocrine carcinomas are a rare type of stomach malignancy, composed of both adenocarcinoma and neuroendocrine tumor-cell comp...

As a palliative bypass for unresectable gastric or periampullary cancer, gastrojejunostomy (GJ) is sometimes associated with postoperative delayed gastric emptying. We report the successful laparoscopic application of this procedure in a 78-year-old man with duodenal obstruction. Computed tomography revealed a mass in the duodenum along with multiple masses in the liver. A radiological image sh...

This graph shows two important results. First, as a group, patients lose a great deal of weight over time, and tend to keep much of it off. For these patients, average excess weight loss at 2 years is 80%, at 4 years is 64%, and 5 years 65%. We do not have enough data to calculate a meaningful average beyond 5 years. Second, there is a great deal of variation among patients. Some drop to a norm...
