Patients aged 1 month to 12 years admitted with an acute abdominal surgical condition comprising 226 cases with and 206 cases without ascariasis, recorded in the operation theatre registers and in-patients clinical sheets, were studied in relation to morbidity, duration of operation and hospital stay and mortality. Annually, 7.5% of laparotomies were due to complications of ascariasis. Operations for ascariasis accounted for 10.6% of all hospital admissions for an acute abdominal emergency. Also, ascariasis accounted for 26.3% of emergency operations. All operated biliary obstruction cases were due to ascariasis. Moreover, 20.4% of all cases of ascariasis with abdominal complications required operation. The mean ages at operation were higher in Ascaris-induced than in non-Ascaris-induced intestinal obstruction (5.1 vs 3 yr), intussusception (3.5 vs 1.2 yr) and volvulus (4.8 vs 1.7 yr). The durations of operation and hospital stay were longer and case fatality rates higher in Ascaris-induced than in non-Ascaris-induced cases. The importance of this study in relation to the socio-economic benefits of controlling ascariasis is discussed.

The clinical and radiological features of 24 cases of childhood intussusception presenting at the University of Benin Teaching Hospital are analysed. Nineteen (79%) children presented before the age of one year and the main symptoms were vomiting 87%, passage of bloody stool 62%, abdominal pain 50% and palpable abdominal mass 33%. The commonest aetiologic agent was ascariasis which was seen in three children. Radiological examination was found most useful in selecting patients for barium hydrostactic reduction, and a case is made for the use of the latter procedure in the treatment of childhood intussusception in developing countries. The high case fatality rate of 25% is related to the late presentation of children to hospital.

Ascariasis is a helminthic infection of global distribution with more than 1.4 billion persons infected throughout the world. The majority of infections occur in the developing countries of Asia and Latin America. Of 4 million people infected in the United States, a large percentage are immigrants from developing countries. Ascaris-related clinical disease is restricted to subjects with heavy worm load, and an estimated 1.2 to 2 million such cases, with 20,000 deaths, occur in endemic areas per year. More often, recurring moderate infections cause stunting of linear growth, cause reduced cognitive function, and contribute to existing malnutrition in children in endemic areas. Ascaris infection is acquired by the ingestion of the embryonated eggs. The larvae, while passing through the pulmonary migration phase for maturation, cause ascaris pneumonia. Intestinal ascaris is usually detected as an incidental finding. Ascaris-induced intestinal obstruction is a frequent complication in children with heavy worm loads. It can be complicated by intussusception, perforation, and gangrene of the bowel. Acute appendicitis and appendicular perforation can occur as a result of worms entering the appendix. HPA is a frequent cause of biliary and pancreatic disease in endemic areas. It occurs in adult women and can cause biliary colic, acute cholecystitis, acute cholangitis, acute pancreatitis, and hepatic abscess. RPC causing hepatic duct calculi is possibly an aftermath of recurrent biliary invasion in such areas. Ultrasonography can detect worms in the biliary tract and pancreas and is a useful noninvasive technique for diagnosis and follow-up of such patients. ERCP can help diagnose biliary and pancreatic ascariasis, including ascaris in the duodenum. Also, ERCP can be used to extract worms from the biliary and pancreatic ducts when indicated. Pyrantel pomoate, mebendazole, albendazole, and levamisole are effective drugs and can be used for mass therapy to control ascariasis in endemic areas.

Many dangerous surgical complications like intestinal obstruction, acute appendicitis with perforation, ileal perforation in a typhoid patient, Meckel's diverticulitis, disruption of post operative intestinal anastomosis, volvulus, and intussusception are known to occur due to ascariasis, with considerable morbidity and mortality. In this retrospective study of 250 cases of gastrointestinal ascariasis admitted in paediatric surgical wards of Govt. Medical College, Jabalpur (MP), the authors analysed the results of conservative (especially the use of hypertonic saline enema-given just like an ordinary soap water enema but substituting freshly made hypertonic saline in place of soap water) and surgical treatment. The success rate of conservative treatment was 95.6%. Hypertonic saline passes through the incompetent ileo-caecal valve (present in 80% of children) and irritates the worm bolus commonly situated in the terminal ileum, causing it to disintegrate. It also helps to increase the intestinal motility and passage of worms into the colon. The use of hypertonic saline enema is safe and effective in the conservative treatment of gastrointestinal ascariasis. Authors feel that it is the most grossly under utilized part of conservative treatment and deserves to be known and used on wider scale.

Infestation with Ascaris lumbricoides (roundworm) is very common in the tropics and subtropics. Patients with ascariasis can be asymptomatic or may present with different clinical features in the form of simple nausea, decreased appetite, abdominal pain or more severe bowel obstruction, perforation, intussusception, biliary colic etc. Ultrasonography (USG) can be quick, safe, noninvasive and relatively inexpensive tool in diagnosing the presence of worms and also evaluating response to treatment (1, 2, and 3). Here we present four cases of roundworm infestation presenting with acute abdomen in the emergency department, which were diagnosed by USG and further imaging features of ascariasis on USG is described.

Ascaris Lumbricoides is the most common worm found in human beings and it is the largest of the intestinal nematodes parasitizing humanity. The most common complication of Ascariasis is mechanical bowel obstruction caused by a large number of worms. Bowel obstruction can also be caused by various toxins released by the worms. A large worm bolus can also cause volvulus or intussusception. We report a case of Intestinal Obstruction due to an Ileal MZBCL in an Ascaris. Lumbricoides infestation setting.

Ascariasis is a common worm infestation in developing and under-developed countries. It is caused by the ingestion of food contaminated with Ascaris eggs from faeces and is more common in places with poor sanitation. Almost 25% of the world population is infested by Ascaris lumbricoides. Although ascariasis is a chronic disease, it can present as acute abdomen rarely. The wandering nature of Ascaris in and out of the bowel causes various abdominal complications such as intestinal obstruction, perforation, biliary ascariasis, pancreatic ascariasis, liver abscess, appendicitis, and Meckel's diverticulitis. Intestinal obstruction is the most common complication seen in children and is usually due to mechanical bowel obstruction, volvulus or intussusception. Mechanical obstruction by a bolus of worms is the most common cause of bowel obstruction. Perforation of bowel is rarely reported and it usually occurs in the diseased segment of bowel or following trauma. Perforation of an ileal volvulus secondary to ascariasis has been reported rarely. We present a 4-year-old boy who presented to the emergency room with features of bowel perforation and sepsis, after unsuccessful management for intestinal obstruction in another hospital. On laparotomy, the small bowel was teaming with Ascaris worms. Ileum showed a volvulus with closed loop obstruction and perforation. Peritoneal lavage with resection and ileostomy was done, which was closed at a later date. Anti-helminthic agents were started postoperatively and the boy recovered uneventfully.
