Gastric outlet obstruction in Ogbomoso, Nigeria.

Forty-three patients were operated upon for gastric outlet obstruction over an eight year period. Six (14%) of these patients bad malignant gastric outlet obstruction. Three groups of procedures were used: truncal vagotomy and drainage (TV-D) in 32 patients, highly selective vagotomy and drainage (HSV-I)) in 8 patients, and gastric resection with or without vagotomy in 3 patients. Post-operatively, it took an average of 6.6 days for patients to recommence oral intake (6.2 days for patients who underwent truncal vagotomy and 8.5 days for those who underwent highly selective vagotomy). There were no deaths; immediate post-operative morbidity included gastric atony in 21% and wound infection in 7% of the patients. Long-term complications include postvagotomy diarrhea in one patient and dumping in two patients. One patient had a recurrence of gastric outlet obstruction necessitating re-operation.
