Management of Common Bile Duct Stone Late after Laparoscopic Roux-en-Y Gastric Bypass for Obesity

Rapid weight loss following Roux-en-Y gastric bypass (RYGBP) for the treatment of obesity call increase the incidence of cholelithiasis formation. Nevertheless, routine simultaneous cholecystectomy at the time of bariatric surgery remains controversial. However. in case of delayed Occurrence of common, bile duct (CBD) stones. the difficulty to reach endoscopically the biliary tract after RYGBP should be kept in mind. We here report the case of a patient who presented with CBD stones seven years after gastric banding followed five years later by RYGBP without associated cholecystectomy. Our approach of transgastric laparoscopic assisted endoscopic retrograde cholangiopancreaticography followed by sphincterotomy and balloon stories extraction is illustrated

Alcohol dependence is associated with reduced plasma and fundic ghrelin levels.

Background Conflicting data concerning the involvement of ghrelin in the pathophysiology of alcohol dependence have been reported. The aim of this study is to investigate how chronic alcohol ingestion influences plasma ghrelin levels and whether potential changes observed in plasma relate to modifications in ghrelin production in the stomach where this peptide is primarily synthesized. Materials and methods Fifty-one consecutive alcoholics admitted for alcohol withdrawal were prospectively enrolled and compared to a control group of 32 healthy volunteers matched for age, sex, height and weight. All subjects underwent fasting plasma ghrelin determination. Twenty-seven randomly selected alcoholics and 17 controls underwent gastroscopy for fundic and duodenal biopsies. Tissues were fixed for histology or frozen in liquid nitrogen for ghrelin protein and mRNA determinations by a radioimmunoassay and quantitative polymerase chain reaction, respectively. Alcohol consumption was normalized to body weight (BW) or body mass index (BMI) given the influence of BW and volume distribution on alcohol levels. Results Plasma and fundic ghrelin protein levels were significantly decreased in alcoholics. Fundic but not plasma ghrelin protein levels inversely correlated with alcohol consumption normalized to BW or BMI. Ghrelin mRNA levels in fundic biopsies were similar in alcoholics and controls. No significant differences in duodenal ghrelin protein and mRNA levels were found between both groups. Conclusions Alcoholism was associated with decreased plasma ghrelin levels partly due to reduced ghrelin production in the stomach. Alcohol affected ghrelin production on the post-transcriptional level in the fundus, whereas duodenal ghrelin secretion did not respond in a similar manner to alcohol intake

Endoscopic ultrasound-guided perivascular pancreatic radiofrequency ablation using a hydroxyethyl starch solution prior to pancreatectomy.

Pancreatic surgery remains complex, particularly for borderline resectable and locally advanced tumors. Vascular invasion compromises resectability, and vascular resection entails increased morbidity and mortality. Following a feasibility and safety demonstration of augmented endoscopic ultrasound (EUS)-guided radiofrequency ablation (RFA) using hydroxyethyl starch (HES) in porcine pancreatic parenchyma, the present study assesses whether this approach (EUS-sugar-RFA) in the pancreatic perivascular space is safe and creates a controllable margin of necrosis to enable a vessel-sparing resection. EUS-sugar-RFA in the pancreatic parenchyma adjacent to the splenic artery and vein was performed in a live animal model. Following different survival periods (0-4 days) in the interventional group (n = 3), open pancreatectomy was carried out. The control group (n = 4) included open pancreatectomies in two pigs with non-treated pancreases and in two with pancreatic RFA alone on the same day. All procedures were completed successfully, without intraoperative or postoperative complications. Survival periods were uncomplicated. Histopathological examination showed local necrosis and inflammatory reaction at the ablation sites. Vascular wall integrity was preserved in all specimens. The untreated pancreatic zones in the interventional group were no different from the normal pancreases in the control group. Preoperative perivascular augmented RFA using HES was safe, and in the pancreatic animal model, the best timeframe was within 24 hours before pancreatic surgery. This technique might improve resectability in selected borderline and locally advanced pancreatic cancers

Laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography in bariatric Roux-en-Y gastric bypass patients.

Performing endoscopic retrograde cholangiopancreatography in bariatric patients who underwent Roux-en-Y gastric bypass surgery is challenging due to the long anatomical route required to reach the biliopancreatic limb

Combined endoscopic ultrasonography and endobronchial ultrasound-fine-needle aspiration for evaluation of mediastinal lymph nodes.

Endoscopic ultrasonography (EUS) and endobronchial ultrasound-fine-needle aspiration (EBUS-FNA), is an accurate technique for evaluation of mediastinal lymph nodes (MLN) and stadification of lung cancer. The aims of the study are to evaluate the feasibility and the efficacy of the combined technique compared with mediastinoscopy for the diagnosis of MLN
