The relative frequency and distribution of occurrence of immunoreactive cells in the proventriculus, diverticulum, cardia, fundus and pylorus of the stomach of pigs were investigated by PAP method using specific antisera against BCG, Gas/CCK, 5-HT, somatostatin, glucagon, BPP, motilin and insulin. In the diverticulum and cardia, BCG-, 5-HT-, somatostatin- and glucagon-immunoreactive cells were detected. In the fundus, BCG-, 5-HT- and somatostatin-immunoreactive cells were also found. In the pylorus, BCG-, Gas/CCK-, 5-HT-, somatostatin- and glucagon-immunoreactive cells were observed. However, no BPP-, motilin- and insulin-immunoreactive cells were found in the stomach epithelium of the pigs. These results showed that the occurrence of the endocrine cells confirmed in the diverticulum as the cardia and suggest that the function of diverticulum may be similar to that of cardia in the pigs.

A fistulous communication between an esophageal traction diverticulum and the tracheobronchial tree appears to be of rare occurrence. This report reviews the feature of benign esophagobronchial fistula due to esophageal traction diverticulum. This 36-year-old female patient suffered from substernal pain, interscapular pain and severe paroxysmal coughing after ingestion of fluids. This patient was taken a diverticulectomy and partial resection of superior segment of right lower lobe. After the operation, there was no subjective symptoms, esophagobronchial fistula, leakage, stricture and diverticulum. The postoperative result was excellent.

A vitelline duct (VD) anomaly is a relatively common congenital abnormality of the umbilical area. The anomalies include patent vitelline duct (PVD), cyst, fistula or sinus. The incidence is approximately 2% of the populations, but development of symptoms is rare. Recently, we experienced two cases; PVD accompanied by a small omphalocele and intestinal volvulus due to mesenteric band between Meckel's diverticulum and the mesentery. Thereafter,we evaluated the data of vitelline duct anomalies for 27 years. From 1980 to 2006, 18 cases of VD anomalies were reviewed based on the hospital records retrospectively. There were 15 boys and 3 girls and age ranged from 2 days to 15 years. Among the 18 cases, 15 cases were symptomatic and consisted of Meckel's diverticulum (10 cases), PVD (4 cases) and umbilical polyp (1 case). Three asymptomatic cases of Meckel's diverticulum were found incidentally were and were observed without resection. Ten cases of Meckel's diverticulum were presented with intestinal bleedings (4 cases), intestinal obstructions (5 cases) and perforation (1 case). Wedge resections and segmental resections of ileum were performed in 8 patients and 2 patients, respectively. Postoperative complications were adhesive ileus (1 case) and wound seroma (1 case). Small omphaloceles were accompanied in two of 4 PVD patients. There was 1 small omphalocele case which was accompanied by a prolapse of ileum. In summary, VD anomalies were more common in male and more than half of them were found in patients less than 1 year of age. PVD was diagnosed most frequently in neonates. Meckel's diverticulum presented with intestinal obstruction more frequently than bleeding.

Meckel's diverticulum (MD) occurs in approximately 2 % of the population. The major complications of MD are bleeding, intestinal obstruction, infection and perforation. Perforation is the least common but most serious complication, the incidence od which is about 5-10 %. The causes of perforation are inflammatory diverticulitis and peptie ulceration. the purpose of study is to review the characteristics of perforated MD in children. Six patients with perforated MD who had been operated upon at the Department of Pediatric Surgery, Yeungnam University Hospital from April 1984 to July 2001 were included. Male predominated in a ratio of 5:1 and there were 2 neonates. The chief complaints were abdominal pain and distension. Half of the children showed a past history of bloody stools. The average age was 4 year and 9 months. The mean distance from the ileocecal valve to the diverticulum was 60 cm. Average length of the diverticulum was approximately 3 cm and width was 1.7 cm. The perforation site was the tip of the diverticulum in 3 cases, the base in 2 cases and along the lateral border in one. In two patients, ectopic gastric mucosa was found in the specimen. All of the patients were operated upon with a diagnosis of peritonitis of unknown etiology. In conclusion, when a child shows symptoms of acute abdomen or peritonitis, especially in boys, with the history of bloody stools and episodic abdominal pain, perforated MD should be suspected.

Purpose : The diagnosis of Meckel's diverticulum is difficult and delayed because it presents with various clinical symptoms. We evaluated clinical, imaging and pathologic findings of Meckel's diverticulum to facilitate detection of Meckel's diverticulum in children. Methods : Review of clinical, imaging, surgical and pathological findings in 10 children aged 7 days to 14 years with Meckel's diverticulum during an 8-year period, 1993-2001, at Ewha Womans University Hospital was undertaken. Results : The male to female ratio was 2.3 : 1. The chief complaint was painless lower gastrointestinal( GI) bleeding; others were abdominal pain, abdominal distention and vomiting, in order of frequency. The diagonsis before surgery were Meckel's diverticulum in 5 patients, non-reducible intussusception in 3 patients and intestinal obstruction in 2 patients. The diverticulum was located between 35 cm to 70 cm proximal to the ileocecal valve. The length of the diverticulum ranged from 4 cm to 12 cm and 80% of it was within 5 cm. A Meckel scan($^{99m}Tc-pertechnetate$ scintigraphy) after cimetidine administration was done in 6 cases. All 5 cases that presented with lower GI bleeding had ectopic gastric mucosa confirmed on pathology. Out of 5 cases of ectopic gastric mucosa, only 4 cases were positive on the Meckel's scan. Conclusion : In cases of unexplained GI bleeding, obstruction, or inflammation diagnostic workup should be carried out to rule out Meckel's diverticulum. Laparoscopy, high resolution ultrasonography and computed tomography of the abdomen may be indicated in the assessment of pediatric patient with lower GI bleeding, especially in patients with suspected bleeding from Meckel's diverticulum showing negative Meckel's scan.

Intussusception and Meckel's diverticulum are very rare disorders in intrauterine or neonatal periods, which are causes of intestinal obstruction. We experienced a case of intussusception due to Meckel's diverticulum which caused intestinal obstruction in the neonate who had bilious vomiting a few hours after birth. We report this case with a brief review of the literature.

Tracheal diverticulum is relatively rare. It results from congenital or acquired weakness of the tracheal wall. Most cases are asymptomatic, but when symptoms are present, they are usually nonspecific. A 54-year-old man complained of sputum lasting for several months. Chest computed tomography showed an air-containing cystic structure in the trachea. Fiberoptic bronchoscopy demonstrated ostium arising from the right posterolateral wall at the trachea. Reported herein is a case of eosinophilic bronchitis associated with tracheal diverticulum.

Background: There is no established surgical procedure for the treatment of epiphrenic esophageal diverticulum. The aim of this study was to compare the clinical outcomes of esophageal diverticulectomy using abdominal and thoracic approaches. Methods: We retrospectively reviewed 30 patients who underwent esophageal diverticulectomy through the thoracic or abdominal approach for an epiphrenic diverticulum at a single center between 1996 and 2018. We compared clinical outcomes, including the postoperative length of stay, time from the operation to oral feeding, leakage rate, and reoperation rate between the 2 groups. Results: The median age was 56 years. Of the 30 patients, 18 (60%) underwent diverticulectomy via the thoracic approach and 12 (40%) underwent the abdominal approach. The median hospital stay was 10 days (range, 5-211 days) in the thoracic approach group and 9.5 days (range, 5-18 days) in the abdominal approach group. The median time from the operation until oral feeding was 6.5 days (range, 3-299 days) when the thoracic approach was used and 5 days (range, 1-11 days) when the abdominal approach was used. In the thoracic approach group, the leakage rate was 16.67% and the reoperation rate was 27.78%. However, there were no cases of leakage or reoperation in the abdominal approach group. Conclusion: The abdominal approach for esophageal diverticulectomy is a feasible and appropriate alternative to the thoracic approach.

The anatomy and ultrastructure of the digestive diverticulum of Saxidomus purpuratus were described using light and electron microscopy. The digestive diverticulum of dark green color was situated on the gonad and connected to stomach by a primary duct. Digestive diverticulum is composed of numerous digestive tubules. The epithelial layer of digestive tubule, which is simple, is composed of basophilic cells and digestive cells. Basophilic cells are columnar in shape, and the electron density is higher than that of the digestive cell. The cytoplasm has a well-developed endoplasmic reticulum, tubular mitochondria, Golgi complex and membrane-bounded granules of high electron density. Digestive cells are columnar in shape, with development of microvilli on the free surface. Pinocytic vasicles, lysosomes and numerous mitochondria were observed in the apical cytoplasm of digestive cells. The results of this study suggest that basophilic cells and digestive cells in the digestive tubule are specialized in the extracellular and intracellular digestions, respectively.
