A CLINICO PATHOLOGICAL STUDY ON GASTRIC OUTLET OBSTRUCTION IN AN ADULT POPULATION ATTENDING TERTIARY CARE HOSPITAL, KURNOOL

Abstract

BACKGROUND: Gastric outlet obstruction is a group of clinico-pathophysiological consequence of mechanical impediment of gastric emptying. Clinical entities that can result in gastric outlet obstruction are characterized into benign and malignant causes. The proximal stomach is now the most common site for gastric carcinoma in the west, but in Japan and developing countries like India, the distal gastric cancer ( antrum 13% and pylorus 7% ) still predominates. Diagnosis of gastric outlet obstruction depends on different features and specific investigations. The definitive treatment involves surgical relief of gastric outlet obstruction. The correct surgical procedure to be adopted is planed according to the cause of obstruction and condition of patients. This is an observational study aimed for characterization of gastric outlet obstruction in terms of benign and malignant and their relation to its causes, sites and other related factors in the tertiary care centre (GOVERNMENT GENERAL HOSPITAL, KURNOOL ).

METHODS: This is an observational study of 30 patients of gastric outlet obstruction admitted in the Department of Surgery GGH KURNOOL. The provisional diagnosis was based on detailed clinical history, thorough physical examination, and some radiological examinations.

RESULTS: a majority of patients of gastric outlet were malignant lesions of the stomach, and very few are benign. Antral carcinoma of the stomach was found to be commonest etiology of gastric outlet obstruction followed by pyloric stenosis secondary to acid peptic disorders. Most of the patients were in the age group 40 to 60 years. Males were affected more than females.

CONCLUSION: Gastric outlet obstruction in adults, a surgical problem of either sex, results commonly due to antral carcinoma or pyloric stenosis secondary to acid peptic disorder.
