Pylorus*

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.

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. 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.

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.

Double pylorus is either a congenital abnormality or an acquired complication of peptic ulcer disease. An accessory channel normally connects the lesser or greater curvatore of the prepyloric antrum with the duodenal bulb. Three cases of double pylorus, an unusual complication of peptic ulcer disease is herein reported. A peptic ulcer lay in the accessory channel in all cases. In one of the cases, the fistula closed spontaneously after Helicobacter pylori eradication. The remaining 2 patients became asympto-matic despite the persistence of the accessory channel.

Double pylorus is a rare disease. It is described by a double communication between the gastric antrum and the duodenal bulb. The cause of double pylorus is either a congenital abnormality or an acquired condition. It is believed to be mostly a complication of peptic ulcer disease. Most reports revealed conditions only for the gastric antrum. However, case reports describing the involvement of the gastric body are extremely rare. Herein, we report a case of a double pylorus that developed on the gastric body and we present a review of the literature.
