Intestinal obstruction caused byAscaris Lumbricoides
PURPOSE: The aim of this study is to present patients, to discuss causes of morbidity and mortality, and to ascertain prognostic indexes and therapeutic options influencing outcome of patients with intestinal obstruction caused byAscaris lumbricoides.MATERIALS AND METHODS: During the past 20 years, between 1975 and 1995, a total of 17 patients with intestinal obstruction attributable toA. lumbricoidesunderwent surgery. Five were adults, and 12 were children. The most frequent symptoms and physical findings were abdominal pain, distention, nausea, vomiting, and constipation. Enterotomy was performed in ten patients and resection in two patients. Manual exposition and advancement of the parasitic bundle toward the colon was attempted in five patients. Morbidity and mortality rates were 29 and 17 percent, respectively, and septic shock was the major cause of death. RESULTS: This study suggests that simple bowel obstruction is the fatal complication ofA. lumbricoidesinfestation, which is seen particularly in pre-school and young school-aged children living in unhygienic conditions, and illustrates the need for heightened awareness ofA. lumbricoidesby the emergency physician in the differential diagnosis. CONCLUSIONS: Early diagnosis and surgical intervention are essential to minimize high morbidity and mortality.
