BACKGROUND bariatric surgery is widely employed nowadays. Nutritional complications following malabsorptive bariatric surgery are common. OBJECTIVES to compare protein malnutrition incidence, the amount of protein intake and the influence of various risk factors in patients undergoing Roux-en-Y gastric bypass (RYGB) and biliopancreatic diversion (BPD). METHODS retrospective study comparing ...

A 7 month old infant with pancreatitis and ascites was managed successfully with subcutaneous octreotide and external drainage of a pseudocyst. An endoscopic retrograde cholangiopancreatographic examination showed no congenital abnormality and was consistent with chronic pancreatitis. Octreotide has a possible therapeutic role in pancreatic ascites.

Faecal trypsin levels have been estimated by a photometric azo-casein method in 242 children and 45 adults. Analysis of the results shows that this is not a specific test of pancreatic dysfunction but that it appears to be a useful screening test for the selection of patients who may have severe pancreatic disease and on whom further specific investigations should be performed.

Laparoscopic sleeve gastrectomy (LSG) has been described as the first step of a two-step laparoscopic Roux-en-Y gastric bypass (LRYGB) or biliopancreatic diversion with duodenal switch (BPD-DS) in extremely obese patients. It has also been used as an independent bariatric procedure. Recently a banded sleeve gastrectomy using human dermis was published. Gastric sleeve dilatation is one of the un...

The rapid reversal of diabetes, hypertension, hyperlipidaemia and obesity by surgical means has challenged accepted doctrines regarding the management of metabolic syndrome. Sleeve gastrectomy, which developed initially as a preparatory procedure for biliopancreatic diversion with duodenal switch, has seen an exponential rise in popularity as an effective lone laparoscopic bariatric procedure. ...

To preserve pancreatic endocrine and exocrine function, various types of pancreatic resection, including central pancreatectomy, have been introduced as less invasive surgeries. However, postoperative pancreatic leakage has been demonstrated to be the most frequent complication following pancreas-preserving surgery. The authors' new surgical technique, a jejunal wall-covering method, helps to p...

RESULTSdPancreatic TG levels were higher in Hispanics and whites than in blacks (P = 0.006). Hepatic TG levels were highest in Hispanics (P = 0.004). Compensatory insulin secretion and disposition index were higher in blacks (P = 0.003 and P = 0.024, respectively). Insulin sensitivity was comparable between Hispanics and blacks and was lower than in whites (P = 0.005). In blacks, compensatory i...

The synthesis of mitochondrial DNA (mDNA) in HeLa cells is selectively inhibited by relatively low concentrations of ethidium bromide. After exposure of cells to strongly inhibitory concentrations of the drug, the apparent superhelix density of mDNA is rapidly increased, as judged by its buoyant density in CsCl in the presence of ethidium bromide. Mitochondrial DNA synthesized in the presence o...
