Gastritis cystica polyposa (GCP) is a rare lesion characterized by hyperplastic and cystic dilatation of the gastric mucous glands infiltrating into the underlying submucosa. A cumulative experience suggests that GCP represents a manifestation of a spectrum of reactive inflammatory responses to mucosal injury. The case reported herein is a GCP developed as multiple polypoid lesions with a circular arrangement in the gastric mucosae along the gastrojejunostomy site.

Gastritis cystica profunda (GCP) is a disease characterized by gastric foveolae elongation along with hyperplasia and cystic dilatation of the gastric glands extending into the tisssue beneath the submucosa. It mainly occurs on the site of gastroenterostomy, but can occasionally be found in an unoperated stomach. GCP may present as a submucosal tumor or polyp, and rarely a giant gastric mucosal fold. This lesion has traditonally been regarded as a benign lesion. However, there are many debates over its malignant potential. Further investigations on the relation between GCP and gastric carcinoma may be necessary. To our knowledge, this is the second description of adenocarcinoma arising from GCP in an unoperated stomach.

Enteroenteric anastomotic strictures of UGI tract are common and require treatment if significant obstruction occurs. We performed fluoroscopic guided balloon dilatation in 6 patients who had symptomatic stricture of gastrojejunostomy. The stricture was successfully resolved in 4 patients with benign stricture. But 2 patients with malignant stricture had recurrence of obstructive symptom 2 weeks later, and they required a stent. Asymptomatic balloon rupture was seen in one patient, but other procedural complications did not occur. We found that fluoroscopic guided balloon dilatation is an effective and safe method in the treatment of anastomotic stricture of gastrojejunostomy. We also found transient effect in malignant gastrojejunal anastomotic strictures, which required an interventional procedure, such as placement of a stent.

We introduce a rare case of gastric emphysema. A 68-year-old man presented with vomiting and dyspnea. Simple abdominal X-ray and CT showed marked dilatation of the stomach and abnormal intramural gas consistent with gastric emphysema. We performed gastric decompression via nasogastric tube drainage and parenteral nutritional support. Nine days after admission, the abnormal intramural gas had disappeared on follow-up CT. The acute gastric dilatation in this patient may have resulted from gastric hypomotility as a result of diabetic gastroparesis in addition to superior mesenteric artery syndrome resulting from malnutrition.

PURPOSE: Paclitaxel is a chemotherapeutic agent with potent microtubule stabilizing activity that arrests cells in G2-M phase. Because G2 and M are the most radiosensitive phase of the cell cycle, paclitaxel has potential role as a cell-cycle specific radiosensitizer. This study was performed to see the effects of paclitaxel on the radiation-induced damage of gastric mucosa of the rat. MATERIALS AND METHODS: The rats were divided into the three groups i.e., paclitaxel alone group, radiation alone group and, a combination of paclitaxel and radiation in combined group. A single intraperitoneal infusion of paclitaxel (10 mg/kg) was done in paclitaxel alone group. In radiation alone group, a single fraction of irradiation (8 Gy, x-ray) to the whole abdomen and, a combination of a single fraction of irradiation (8 Gy, x-ray) to the whole abdomen was given 24 hrs after paclitaxel infusion in combined group of paclitaxel and radiation. The incidence of mitosis and apoptosis as well as histologic changes of the gastric mucosa were evaluated at 6 hrs, 24 hrs, 3 days and 5 days after treatment. RESULTS: The number of the mitosis was not increased by paclitaxel infusion. The incidence of the apoptosis was similar from 6 hrs to 3 days after paclitaxel infusion and was decreased at 5 days. Paclitaxel induced minimal glandular dilatation and cellular atypia of gastric mucosa at 24 hrs and 3 days. In irradiation group, the incidence of apoptosis was 6.0% in 6 hrs and 1.25% in 24 hrs after irradiation and minimal glandular dilatation and cellular atypia were noted throughout the experimental period. The incidence of apoptosis in the combined group of paclitaxel and irradiation (4.5%) was significantly higher than irradiation alone group (1.25%) at 3 days (p<0.05). CONCLUSION: Paclitaxel had no effect on mitotic arrest in gastric mucosa of the rat. Increased number of apoptosis in combined paclitaxel and irradiation group suggested the additive effects of paclitaxel on irradiation.

Gas in the portal veins is rare and in most cases is associated with serious diseases and poor clinical outcome. A case of gas in the hepatic-portal veins with gastric dilatation, as shown by CT-scanning for abdominal trauma, is reported. The condition was clinically benign and resolved spontaneously. An abdominal CT scan documented the findings.

PURPOSE: To review the radiologic findings of retroanastomotic hernia and to derive useful US and CT criteria to assist in the diagnosis of the condition in patients who have undergone gastrojejunostomy. MATERIALS AND METHODS: During a recent eight-year period, we encountered 11 consecutive cases of retroanastomotic hernia. Of the patients involved, nine underwent ultrasound (US), eight underwent computed tomography (CT), and in three, small bowel follow-through imaging was performed. The US and CT scans were reviewed to determine abnormal findings; surgical proof was available in all cases. RESULTS: The efferent loop was herniated through the defect created behind the anastomosis in eight cases, both the efferent and afferent loop in two cases, and the afferent loop in one case. Retroanastomotic hernia was prospectively diagnosed in ten of these eleven cases. Among the eight cases of efferent loop herniation, US and CT signs of retroanastomotic hernia included whirling of mesenteric vessels, jejunal loops and mesentery in the periumbilical abdomen (8/8); mural thickening of herniated bowel loops (6/8); dilatation of herniated bowel loops (4/8); (at US) decreased peristalsis of herniated bowel loops (3/7); and (at CT) decreased contrast enhancement of herniated bowel loops (1/5). In one case, US and CT signs of retroanastomotic hernia of the afferent loop included its dilatation and whirling of a short length behind the anastomosis. In two cases, US and CT signs of retroanastomotic hernia of both the afferent and efferent loop included findings of both afferent and efferent loop herniation. CONCLUSION: Retroanastomotic hernia is an important and underdiagnosed condition, and the US and CT findings we have described may permit its accurate diagnosis.

Acute gastric dilatation without obstructive or organic disease is rare, but is possible after a gastric or an abdominal operation in cases of trauma, retroperitoneal hematoma, diabetic gastroparesis, hypoxemia, electrolyte imbalance, etc. However ischemic necrosis due to acute gastric dilatation is very rare and has been reported only in patients who has anorexia nervosa or overeat suddenly. If the distended stomach is not decompressed successfully by using a conservative method or if the process proceeds to ischemic necrosis, operative treatment is necessary. We experienced a case in which the stomach was acutely distended, and mutiple ischemic necroses had developed. The patient was a 27-year-old woman and had no specific underlying disease in her medical history. After overeating, the stomach was distended acutely. During the operation, mutiple ischemic necroses were found in the stomach. A total gastrectomy and Roux-en-Y esophagojejunostomy were performed.
