ABSTRACT
OBJECTIVE: Cystic hydatid disease is a zoonotic infection of humans caused by infection with the larval stage of Echinococcus granulosus. The prevalence rate (5-10%) in Turkana, Northern Kenya is among the highest worldwide. With an increase in foreign travel and migration of peoples, practitioners need to be aware of diseases common in these countries and their rarer manifestations. The objective of this study was to review the management of this disease in a poorly resourced high-prevalence area. METHODS: The surgical records of Kakuma Mission Hospital, Turkana from July 1981 to May 2002 were reviewed. RESULTS: A total of 710 (female : male, 3 : 2) surgical procedures for hydatid disease were recorded, the average age being 27 years (range, 3-65 years). There were 663 patients, and therefore 47 patients had repeat procedures. A total of 52.8% (n = 375) had hepatic cysts (248 right sided, 30 left sided, 97 site undefined), and 10.1% (n = 72) had multiple abdominal cysts. Other intra-abdominal sites included 8.16% mesenteric (n = 58), 2.9% retroperitoneal (n = 21), 3.5% spleen (n = 25), the abdominal wall (n = 4). There was no information on the site of disease in 5.9% of cases (n = 42). More unusual sites were retro-orbital, gluteal, zygomatic, brachial, parotid, uterine, tibial and foot. The largest volume of cyst fluid was 7 l. There was one intraoperative death and one postoperative death recorded. Endocystectomy +/- a scolicidal was the commonest procedure performed. However, 165 percutaneous aspiration injection of a scolicidal agent and reaspiration procedures were performed, six being on pregnant women. This is one of the largest series of surgical hydatid patients from Africa and demonstrates the wide diversity in cyst location.
