Abstract:
The experience of the Digestive Endoscopy Center of the Soavinandriana Hospital in Antananarivo provides insight into not only esogastroduodenal disease in Madagascar but also technical problems involved in performing esophago-gastro-duodenoscopy in tropical areas. From September 1990 to March 1995 a total of 12000 esophago-gastro-duodenoscopy procedures were performed without complication. The main finding was duodenal ulcer which observed in 3580 cases (29.8% of patients) followed by peptic esophagitis due to gastroesophageal reflux in 555 cases and gastric ulcer in 460 cases. Esophageal cancer was detected in 16 cases and malignant gastroduodenal tumor in 82 cases including 63 adenocarcinomas and 5 digestive lymphomas. Overall 4156 procedures (34.6%) were normal and 1130 procedures (9.4%) were performed to investigate digestive tract hemorrhage. These findings document the high incidence of duodenal ulcer in Madagascar where treatment of this condition is difficult due to the high cost. This study underlines the problems encountered in operating an endoscopy department in tropical areas especially with regard to desinfection of equipment and training of endoscopists.
