Congenital hypertrophic pyloric stenosis although rare in native Filipino infants does occur. The recognition of the condition depends upon the awareness of this fact. The different manifestations, both clinical and radiologic are often suggestive of the diagnosis. (Summary)

A Case of double pylorus, in 56 year old man, was diagnosed by fiberoptic gastroscopy and upper gastrointestinal series. Two ovoid large openings of pyloric canal divided by smooth thickened septum were observed endoscopically And the relevant literatures on tihe subject were reviewed.

It has been thought for many years that gastric adenocarcinoma almost never crosses the pylorus. Rokitanski in 1861 made the classic statement that the pyloric served as a barrier to duodenal dissemination of gastric cancer. Although this theory was generally accepted, but direct spread of gastric carcinoma into the duodenum has been reported, most recently in 1965. We report two recent cases of gastric cancer spreading into the duodenum and review the literature.

A 63 year-old man was admatted to our hospital because of dulI epigastralgia. Upper G-I series reveaied the generalized thickened, tortuous mucosal folds in the stomach and duodenal bulb, Two ovold large pits on the antrum were observed endoscopically, Tha relevant literatures on the subject were reviewed.

It has been thought for many years that gastric adenocarcinoma almost never crosses the pylorus. Although this theory was generally accepted, several studies have refuted it. We report three cases of gastric adenocarcinoma direct spreading into the duodenum that was diagnosed by endoscopic duodenal biopsy and review the literature.

So-called, the double channel pylorus has been, relatively rarely, reported through out the world. All reported cases were almostly those of gastroduodenal fistula as a complication of peptic ulcer disease. The congenital forms of double pylorus were reported even more rarely. We found three cases of double channel pylorus in 25,000 cases endoscopy done at our unit. All those three cases were thought to be acqired form endoscopically, radiographically and histologically. One of those was undergone to operative resection because of uncontrollable bleeding and the others were on medical theraphy with satisfaction.

Regarding the removal of a gastric bezoar, laparoscopic surgery was performed and it was shown that the laparoscopic approach is safe and feasible. However, the laparoscopic method has the risk of intraabdominal contamination, when the gastric bezoar is retrieved from the gastric lumen in the peritoneal cavity. We developed and applied a new procedure for the removal of the gastric bezoar using one surgical glove and two wound retractors as a fashion of intragastric single port surgery. Herein we present this new minimal invasive procedure, so named "hybrid access surgery" which involves the use of existing devices and overcomes the weakness of laparoscopic removal of the gastric bezoar. Our new procedure, combining the concept of intragastric and single port access, is acceptable and feasible to retrieve the gastric bezoar. In the future, this procedure may be one of the alternative procedures for retrieving gastric bezoar even when it is incarcerated in the pylorus.

10.Regulation of pyloric rhythm by I(A) and I(h) in crayfish stomatogastric ganglion.

The stomatogastric ganglion (STG) of shellfish includes 30 neurons and produces pyloric rhythms. It is the common model to study central pattern generator (CPG). Regulation of pyloric rhythms not only is related to the property of single neurons in STG but also depends on the connections and property of the whole neuronal network. It has been found that transient potassium current (I(A)) and hyperpolarization-activated cation current (I(h)) exist in certain types of neurons of STG. However, roles played by these two currents in maintaining and regulating the pyloric rhythms are unknown. In the present study, in vitro electrophysiological recordings were performed on crayfish STG to examine the role played by I(A) and I(h) in regulation of pyloric rhythm. 4AP (2 mmol/L), a specific inhibitor of I(A), caused a decrease in pyloric cycle (P < 0.01), an increase in PD (pyloric dilator) ratio, a decrease in PY (pyloric) ratio (P < 0.01) and delay of phases of LP and PY firing. ZD7288 (100 μmol/L), a specific inhibitor of I(h), caused a decrease in pyloric cycle (P < 0.01), an increase in PD ratio (P < 0.01), an increase in LP (lateral pyloric) ratio (P < 0.01), a decrease in PY ratio (P < 0.01) and delay of phases of LP and PY firing. These results indicate that I(A) and I(h) play important roles in regulating pyloric rhythms in crayfish STG.
