Pylorus*

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 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. 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.

Gastroduodenal fistula or double pylorus is a very rare condition. It is a fistulous communication between gastric antrum and duodenal bulb. It can be either congenital or acquired. In most cases it is thought to be a complication of gastric ulcer. We recently experienced a case of gastroduodenal fistula in 70 year-old man presenting as epigastric pain. He was diagnosed with non ST elevation myocardial infarction previously, and was taking aspirin. Gastroduodenal communication was revealed by endoscopy. We report a case of gastroduodenal fistula that developed in man who was taking aspirin, with review of the literature.

Invasive gastric Candida infection in patient with co-morbidity can cause stenotic change if it is developed at anatomically narrowing portion, such as distal antrum, pylorus, or duodenal bulb. However, proper management of benign stenosis by diffuse gastric Candidasis is still under controversy and palliative bypass surgery has several shortcomings because high risk operative group may be included in this case. Palliative placement of self-expandable metallic stent has been settled as a standard management of malignant gastric pyloric obstruction and it is expected to be applied in benign stenotic lesions due to its gradual dilation effect. We described a case of stenosis by diffuse gastric Candidasis at anastomosis of subtotal gastrectomy, which was managed by temporary placement of self-expandable metallic stent.
