Comparative Study
Morbidity and mortality of laparoscopy-assisted gastrectomy with extraperigastric lymph node dissection for gastric cancer.
Gastrectomy with extraperigastric lymph node dissection has not been generally acceptable because of increased morbidity and mortality in some Western countries. Recently, many surgeons have become interested in laparoscopic gastric surgery for malignant disease as well as benign lesions because laparoscopic surgery itself has been shown to have many advantages over open surgery. The aims of this study are to evaluate the incidence and nature of operative morbidity and mortality after laparoscopy-assisted gastrectomy (LAG) with extraperigastric lymph node dissection with respect to surgical experience and to identify factors predictive of complications and death. ⋯ The minor surgical complication rate in the late group was significantly lower than that in the early group (P = 0.0349). According to univariate and multivariate analyses to evaluate the independent predictor of a higher operative morbidity rate, no factor was significantly associated with operative morbidity. We conclude that LAG with extraperigastric lymph node dissection is a technically feasible and acceptable surgical modality for gastric cancer and low morbidity and mortality rates for this procedure can be accomplished by experienced laparoscopic gastric surgeons at large-volume hospitals.

Case Reports
A case of fatal necrotizing pancreatitis: complication of hydrochlorothiazide and lisinopril therapy.
We report a case of fatal necrotizing pancreatitis associated with hydrochlorothiazide and lisinopril therapy. A 49-year-old man who presented with 2 days of abdominal pain and vomiting was found to have severe pancreatitis. The patient denied any alcohol use. ⋯ An exploratory laparotomy was performed and revealed no common bile duct stones. Unfortunately, the patient's hospital course was complicated with multiple organ failure, which resulted in death. To the best of our knowledge, there are only 3 other reported cases of hydrochlorothiazide-induced necrotizing pancreatitis reported in the literature.

This study evaluated the effect of gastric electrical stimulation (GES) with various parameters on plasma concentrations of satiety-related peptides and glucose. GES was performed in nine healthy dogs via electrodes implanted in the middle of the lesser curvature. Four sessions were performed in each animal: control, stimulation with IGS (implantable gastric stimulation for obesity, 0.3 m sec), modified IGS (2 msec), and long pulses (300 msec). ⋯ The total AUC for plasma glucose was significantly lower in sessions with long pulses and modified IGS parameters (P < 0.05). We conclude that acute GES is able to change the release of some satiety-related peptides. Whether this is associated with the changed eating behavior and weight loss in obese patients needs further investigation.
