tum ( fi g. 1 ). A guide wire was advanced through both openings, and this confi rmed that only one continuation of the lumen was present ( fi g. 2 ). After clinical and endoscopic assessment, the patient was diagnosed as having an incomplete congenital septum of the duodenal bulb. Acquired double pylorus occurs when peptic ulcer disease leads to the formation of a pyloroduodenal fi stula in wh...

BACKGROUND/AIMS The role of the enteric (ENS) and central (CNS) nervous systems in the control of the retrograde giant contraction (RGC) associated with vomiting is unknown. METHODS The effects of myotomy or mesenteric nerve transection (MNT) on apomorphine-induced emesis were investigated in 18 chronically instrumented dogs. RESULTS Neither surgery affected the RGC orad of the surgical sit...

A decrease in pyloric myoelectrical activity and pyloric substance P (SP) content following intrasphincteric injection of botulinum toxin type A (BTX-A) in free move rats have been demonstrated in our previous studies. The aim of the present study was to investigate the inhibitory effect of BTX-A on rat pyloric muscle contractile response to SP in vitro and the distributions of SP and neurokini...

OBJECTIVE Delayed gastric emptying after esophageal operations occurs in up to 50% of patients. A good quality of life, in long-term survivors after esophagectomy, may depend on both dietary adaptation and the improvement of intrathoracic gastric motility itself. The objective of this study was to investigate the effect of pyloric balloon dilatation on the sustained delay of gastric emptying af...

BACKGROUND Pancreatoduodenectomy is an established procedure for the treatment of benign and malignant diseases located at the pancreatic head and periampullary region. In order to decrease morbidity and mortality, we devised a unique technique using two different jejunal loops to avoid activation of pancreatic juice by biliary secretion and therefore reduce the severity of pancreatic fistula. ...

Alphabaculovirus is an entomopathogenic virus genus that infects Bombyx mori, which is known as the Bombyx mori multiple nucleopolyedrovirus (BmMNPV). This virus is polyorganotrophic, and a series of tissues are known as targets; however, there is currently no information regarding infection in the pylorus, the segment of the hindgut that is present in the midgut transition and is responsible f...

Background This study aimed to evaluate the effects of the position of an acetic acid-induced gastric ulcer and the effects of prokinetic drugs on gastric emptying. Materials and Methods Male Sprague-Dawley rats were used in this study. Acetic acid ulcers were induced either in the region between the fundus and pylorus on the anterior wall of the stomach or in the glandular region on the greate...
