A single intraperitoneal injection of endotoxin (40 microg/kg) significantly delayed gastric emptying of a solid nutrient meal. Blockade of nitric oxide synthase (NOS) with 30 mg/kg ip N(G)-nitro-L-arginine methyl ester or 20 mg/kg ip 7-nitroindazole [neuronal NOS (nNOS) inhibitor] significantly delayed gastric emptying in control animals but failed to modify gastric emptying in endotoxin-treat...
Adenocarcinoma of the distal duodenum: two cases managed by pylorus preserving pancreatico-duodenectomy and adjuvant chemotherapy Primary adenocarcinoma of the duodenum is a rare tumour which accounts for less than 0.5% of intestinal malignancies 1, 2, and the optimum treatment is unknown. Previous surgical treatment has consisted ofWhipple type pancreatico-duodenectomy or segmental resection ,...
We report a 71-year-old man who had undergone pylorus-preserving pancreatoduodenectomy (PPPD) using PPPD-IV reconstruction for cholangiocarcinoma. For 6 years thereafter, he had suffered recurrent cholangitis, and also a right liver abscess (S5/8), which required percutaneous drainage at 9 years after PPPD. At 16 years after PPPD, he had been admitted to the other hospital because of acute puru...
The present study was designed to compare ulcer protective effect of proton pump inhibitors viz. omeprazole, rabeprazole and lansoprazole against dexamethasone plus pylorus ligation induced ulcer model. Dexamethasone (5 mg/kg) was used as an ulcerogen. Dexamethasone suspended in 1% CMC in water was given orally to all the rats 15 min after the pylorus ligation. Omeprazole (20 mg/kg), rabeprazol...
The role of nitric oxide (NO) and ATP in the regulation of nonadrenergic, noncholinergic (NANC) inhibitory transmission in the pylorus remains unclear. In the presence of atropine and guanethidine, electric field stimulation induced NANC relaxations in a frequency-dependent manner (1-20 Hz) in the rat pylorus. NANC relaxations were significantly inhibited by N(G)-nitro-L-arginine methyl ester (...
The relative contributions to gastric emptying from common cavity antroduodenal pressure difference ("pressure pump") vs. propagating high-pressure waves in the distal antrum ("peristaltic pump") were analyzed in humans by high-resolution manometry concurrently with time-resolved three-dimensional magnetic resonance imaging during intraduodenal nutrient infusion at 2 kcal/min. Gastric volume, s...
ISENBERG, JON I., AND ATTILA CSENDES. Efect of octapeptide of cholecystokinin on canine pyloric pressure. Am. J. Physiol. 222(2) : 42843 1. 1972.-Intraluminal pressure was measured in five dogs with gastric and duodenal cannulas. Open-tipped perfused tubes were used as pressure sensors. To localize the pylorus (i.e., gastroduodenal junction), transluminal potential difference was recorded. The ...
Previous studies on the distribution of parietal cells and G cells in normal adult stomachs have shown that in about 20% of specimens parietal cells extended to the pylorus. This study aimed to examine the distribution ofparietal cells and G cells in the body and antrum of the developing human stomach in relation to anatomical landmarks, using histological and immunocytochemical methods. In all...
Synthetic 13-norleucine-motilin (13-nle-motilin), structural and biological analogue of the naturally-occurring duodenal polypeptide, motilin, is known to stimulate antral and duodenal motor activity in vitro, but delays gastric emptying in man. In this study the direct actions of the synthetic polypeptide on myoelectrical activity and intraluminal pressure have been studied in the isolated vas...
We report a rare case of obstructive jaundice caused by a tuberculous abscess in the head of pancreas, mimicking carcinoma. The case was successfully treated by pylorus-preserving proximal pancreatoduodenectomy and antituberculous drugs.
