1. Although a pause in respiration during swallowing is a feature common to all mammals, inhibition usually occurs during expiration in adult humans and during inspiration in most other species. We tested the hypothesis that this difference is due, at least in part, to the position of the body while feeding. 2. The coordination of respiration and swallowing(More)
Lumbar hernias, rarely seen in clinical practice, can be acquired after open or laparoscopic flank surgery. We describe a successful laparoscopic preperitoneal mesh repair of multiple trocar-site hernias after extraperitoneal nephrectomy. All the key steps including creating a peritoneal flap, reducing the hernia contents, and fixation of the mesh are(More)
The prevalence of morbidly obese individuals is rising rapidly. Being overweight predisposes patients to multiple serious medical comorbidities including type two diabetes (T2DM), hypertension, dyslipidemia, and obstructive sleep apnea. Lifestyle modifications including diet and exercise produce modest weight reduction and bariatric surgery is the only(More)
HYPOTHESIS Laparoscopic liver surgery is significantly limited by the technical difficulty encountered during transection of substantial liver parenchyma, with intraoperative bleeding and bile leaks. This study tested whether the use of a bioabsorble staple line reinforcement material would improve outcome during stapled laparoscopic left lateral liver(More)
BACKGROUND Leaks after sleeve gastrectomy (SG) may be due to a mismatch between staple height and tissue thickness. The aim of this study was to determine the range of gastric thicknesses in three areas of stapling. METHODS SG was performed using a 40-Fr suction calibration system 4 cm from the pylorus. Measurement of combined gastric walls was(More)
BACKGROUND During recent years laparoscopic cholecystectomy has dramatically increased, sometimes resulting in overtreatment. Aim of this work was to retrospectively analyze all laparoscopic cholecystectomies performed in a single center in order to find the percentage of patients whose surgical treatment may be explained with this general trend, and to(More)
Only 10% to 20% of pancreatic tumors are resectable at the time of diagnosis. Patients with advanced disease have a median survival of 4.9 months. Palliation is often required for biliary or duodenal obstruction, or both, and for pain. Optimal palliation should guarantee the shortest possible hospital stay and as long a survival as possible with a good(More)
BACKGROUND Partial bypass of the GI tract may promote weight loss by decreased absorption of nutrients and changes in incretins. The aim of the study was to evaluate the safety and efficacy of performing a side-to-side duodeno-ileal anastomosis. METHODS Seven 40-50 kg female Yorkshire pigs were allocated to a duodeno-ileal anastomosis (DIA), and were(More)

BACKGROUND Esophagogastric fistula following an esophagectomy for cancer is very common. One of the most important factors that leads to its development is gastric ischemia. We hypothesize that laparoscopic gastric devascularization and partial transection is a safe operation that will enhance the vascular flow of the fundus of the stomach. METHOD Our(More)
