Surgical Treatment for Chronic Peptic Ulcer with Gastric Outlet Obstruction

PURPOSE: With the introduction of H. pylori eradication and proton pump inhibitor, the operative treatments for the acute or chronic complications of peptic ulcer, such as perforation, bleeding and stricture, have decreased. Also owing to the development of non-operative treatment such as interventional endoscopic treatment, the surgical approach to the acute complications, like perforation and bleeding, has diminished. The non-operative treatments for the stricture and obstruction of chronic peptic ulcer in part related to discontinuation of medication have not been satisfactory. We analyzed the clinical outcomes of the patients who underwent operative treatment for outlet obstruction with peptic ulcer. Materials of Methods: From January 1994 to December 2007, we reviewed 31 patients who had been operated on at the National Medical Center for peptic ulcer obstruction. We excluded the cases of adhesive obstructions that were caused by a former ulcer operation and also the cases of obstructions found during emergency operations for treating perforation and bleeding. We classified the surgical treatment group into the bypass operation group and the surgical resection group. We evaluated the effects of the operations by the Visick score. The recurrences were confirmed only by the endoscopic observation of peptic ulcer. RESULTS: The number of patients in the bypass operation group was 6 (19.4%) and that of resection group was 25 (80.6%). The mean age was 57.5 (25~81) years. The number of male patients was 29 (93.5%) and the number of females was 2 (6.5%). The mean symptom duration was 29.6 months. There were 19 smokers (61.3%), 6 NSAID users (19.4%) and 7 H. pylori positive patients (22.6%). Two patients underwent endoscopic balloon dilatation with no success. The locations of lesion were the stomach, the duodenum and both in 9, 20 and 2 cases, respectively. There were operative complications in 13 cases (41.9%), recurrent ulcers in 2 cases (6.5%), and reoperations in 4 cases. The mean Visick score was 1.8 (1~4). There were no statistically significant clinicopathologic differences between the bypass operation group and the resection group. The two groups had 1 case each of recurrence. Although the bypass group had a greater complication rate (83.3%) than the resection group (32%), this was not statistically meaningful (P=0.175). The mean Visick score was 3.0 in the bypass group and 1.6 in the resection group, so the resection group was better (P=0.001). CONCLUSION: For a case of chronic peptic ulcer with outlet obstruction, even though it has been reported that endoscopic balloon dilatation worked well, surgery is still regarded as an important treatment. If you consider the patients' satisfaction and the difficulty of diagnosing malignant ulcers, surgical resection should be recommended more often than a bypass operation.

Clinicopathologic Analysis of Gastric Carcinoma Patients with Outlet Obstruction

PURPOSE: This study was conducted to analyze the clinical course of patients of gastric cancer with outlet obstruction by comparing them with the gastric cancer patients without outlet obstruction. METHODS: The records of gastric cancer patients with outlet obstruction and who underwent radical gastrectomy from January 1996 to December 2005 were retrospectively reviewed and compared with those patients with gastric cancer and who were without outlet obstruction. RESULTS: The number of the patients who underwent radical gastrectomy was 461. Out of 461 patients, the number of gastric cancer patients with outlet obstruction was 42 (9.1%), and they had nasogastric tube insertion for an average of 4.4 days before operation. These patients showed several significant features such as large tumor size, advanced stage, an increased the number of involved LNs, a low serum albumin level, a frequent antral tumor location and duodenal invasion. There was no difference in complication rates between the two groups, but a higher mortality rate was noted in the gastric cancer patients with outlet obstruction than that in the other patients (P=0.038). The survival rate after the operation was significantly lower among the gastric cancer patients with outlet obstruction (P=0.0008), whereas no difference was found in the survival rate between the above two groups at the same stage (P=0.1951). CONCLUSION: The gastric cancer patients with outlet obstruction showed a comparatively poorer prognosis than those gastric cancer patients without outlet obstruction. However, there was no significant difference in the complication rate and the survival rate for both types of patients who were at the same stage. These results suggest that the patients with outlet obstruction can show the same result as the patients without outlet obstruction by undergoing radical gastrectomy.

A Case of Pancreaticobiliary Duct Obstruction due to Pancreatic Tuberculosis Combined with a Colon Adenocarcinoma and Tuberculous Colitis / 대한소화기내시경학회지

Systemic manifestation of tuberculosis is common, but tuberculous biliary obstruction of the pancreas and a colon adenocarcinoma with combined colonic tuberculosis is an uncommon disorder. We encountered a case of the above condition in 63-year-old male that was admitted to our hospital because of fever, diffuse abdominal pain and rigidity. Abdominal computed tomography showed biliary and pancreatic duct dilatation with left colonic wall thickening and surrounding peritoneal infiltration. Emergency segmental resection of the descending colon with intraoperative T-tube choledochostomy was performed due to the colon mass and biliary obstruction. A colonofiberoscopy was performed for low abdominal pain and hematochezia at 12 days after surgery. It showed multiple colonic ulcerations with a partial stricture. A colonic biopsy showed granulomatous inflammation with acid-fast bacilli. The cause of the biliary obstruction was also revealed as pancreatic tuberculosis by an intraoperative pancreatic and mesenteric biopsy. The patient improved after antituberculous treatment and the patient has been in good health until the last outpatient follow-up visit.
