Retrospective histopathological analysis of various neoplasms of different parts of the gastrointestinal tract seen at the Kathmandu University Teaching Hospital (KUTH), Dhulikhel, Nepal

Objective: To find out the spectrum of various histopathologic types of primary neoplasms of different parts of the gastrointestinal tract (oesophagus, stomach, small intestine, colorectum, anal canal) seen at the Kathmandu University Teaching Hospital (KUTH), Dhulikhel as there exists a worldwide wide variation in the distribution of various neoplasms of different parts of the gastrointestinal tract, which appears largely due to exogenous factors rather than due to inherent differences between populations. Materials and methods: This was a retrospective study. It was carried out at Kathmandu University Teaching Hospital (KUTH), Dhulikhel, Kavre, Nepal. All neoplasms of the gastrointestinal tract seen at the KUTH during the period 1st January 2004 to 31st December 2004 were included in this study and examined by light microscope (LM). Results: A total number of 18 cases of neoplasms of the gastrointestinal tract were seen. Out of these, 3 (16.7%) were of the oesophagus (all squamous cell carcinoma), 10 (55.5%) were of the stomach (six intestinal type and four diffuse type), 2 (11.1%) were of the small intestine (one was lymphoma of the mucosa associated lymphoid tissue - MALTOMA and other was a malignant gastrointestinal stromal tumour - GIST), 3 (16.7%) were of the colorectum (all adenocarcinoma), and none was of the anal canal. Conclusion: Relatively large number of cases of the carcinoma of the stomach were found in our this small series of the cases of the gastrointestinal tract in comparison to the Western countries. Key words: Neoplasms, gastrointestinal tract, gastric carcinoma intestinal type, gastric carcinoma diffuse type, Kathmandu University Teaching Hospital (KUTH).
