Pylorus*

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.

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.

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.

The Heterotopic pancreas is defined as the presence of pancreatic tissue lacking anatomical and vascular continuity with the main body of pancreas. Heterotopic pancreas or ectopic pancreas is found in 0.55% to 13.7% of autopsy series and also found one in approximately every 500 operations in abdominal surgery. The most common sites are the antrum of stomach, duodenum, and proximal jejunum. Most masses of heterotopic pancreas in stomach were encountered in the distal one third, usually within 5 or 6 cm of pylorus. We have recently experienced a case of hetertopic pancreas that was located in fundus which is not the usual site. Gastrofiberscopy revealed a 2 2.5 cm sized protruding mass on the fundus. There was apperared an umbilical shaped dimple on the center with a relatively normal mucosa. Endoscopic ultrasonography revealed a 2.5 cm sized hypoechoic mass of fundus, originating from submucosal and muscular layer. It was considered a submucosal tumor, such as leiomyoma, and subsequently wedge resection was performed. Histologic finding showed pancreatic acni.

OBJECTIVETo investigate the efficacy of surgical management for pyloric stenosis induced by gastrointestinal chemical burn in children.

METHODSClinical data of 11 children with pyloric stenosis induced by gastrointestinal chemical burn were analyzed retrospectively. After the failure of medicine, intervention of low balloon expansion and stent placement, they underwent pylorectomy and gastroduodenostomy. The body weight, height, serum albumin, hemoglobin, transferrin were compared between 1 day before and 3 months after operation.

RESULTSThere were 10 males and 1 female with a mean age of 4.5 years old. The main cause of serious pyloric stenosis was the wrong intake of hydrochloric acid. Lesions involved the esophagus and stomach in the early stage, and 4 weeks later, the lesion mainly involved the pylorus, which resulted in scarring pyloric stenosis and complete pyloric obstruction. Pylorectomy and gastroduodenostomy was successfully performed. The mean operative time was (134±26) min. The estimated blood loss was (5±2) ml. The postoperative length of stay was (10±3) d. There were no surgical complications. During the follow-up of 3 months, all the patients resumed regular diet. The height, body weight, and intelligence appeared to be normal. They showed significant improvement in weight, serum albumin, globulin, hemoglobin, transferrin at 3 months after the surgery(P<0.05). Six months after surgery, the anastomosis was shown to be nornal in barium follow through exam with no signs of stricture of ulcer.

CONCLUSIONPylorectomy and gastroduodenostomy is an effective management for pyloric stenosis induced by gastrointestinal chemical burn in children, whose short-term efficacy is good.
