At the University College Hospital, Ibadan, Nigeria, a common differential diagnosis of acute abdomen is intestinal ascariasis. This condition mimics many causes of acute abdomen so that accurate pre-operative diagnosis depends mainly on a high index of suspicion.The purpose of this paper is to call attention to this condition which is prevalent in tropical countries, where preventive and social medicine have not reached their peak, and to review the pathological processes resulting from this disease.

Infection with the roundworm Ascaris lumbricoides is common in children and may mimic an acute abdomen. The cases of two pediatric patients who presented to the emergency department with signs and symptoms of a surgical abdomen are presented to highlight the presentation of this infection. Both cases were diagnosed by physical examination and radiographs and were treated successfully without surgical intervention. These cases illustrate the need for heightened awareness by the emergency physician of ascariasis in the differential diagnosis of acute abdomen.

A pregnant woman may be infected up to a 90% by intestine parasites, and it all depends on the geographical area associated to the environmental factors allowing this to be spread. The abdominal obstruction related to the pregnancy is rare due to the fact that it only happens in one out of 2,500-6,000 pregnancies. This occlusion, when given by Ascaris lumbricoides, is even more complicated due to the lack of medical literature reference, and thus being unable to make any comparisons. A 45-year old pregnant woman, with several births and multi-pregnancies presenting an acute abdomen by intestinal obstruction through out this helmint. She was pacticed an exploratory laparotomy with the evacuation of several ascaris throughout and enterostomy, and then during the 37th week, she gave birth by means of an eutocic labor work to a healthy female product weighting 2.825 kgs. The anatomopathology study of the placenta shows no alterations. The nosology of the intestinal obstruction by ascariasis during the pregnancy, and out of it, are very similar and could only be affected by late diagnosis of the pregnant woman due to anatomical and physiological changes, increasing the mother's and the fetus morbi-mortality. In Mexico, there are endemic areas where it would be convenient to identify the characteristical eggs in the mother's stool due to the fact that if an advanced pathology is not put in place, it does produce states of maternal malnutrition, anaemia, abdominal pain and low weigh product at the moments of its birth.

Ascariasis is a helminthic infection commonly found in tropical climates. It often propagates in communities of low socioeconomic status secondary to contamination of the soil and water supply with human feces. We present a case report of a 42-year-old Asian-Indian female presenting with a long-standing history of severe recurrent postprandial epigastric pain, requiring multiple hospital admissions. Ultrasound, computed tomography (CT), and nuclear biliary scan were negative. She underwent esophagogastroduodenoscopy that suggested ischemia. Magnetic resonance angiography (MRA) and mesenteric angiography were inconclusive. As conservative treatment had been unsuccessful, a small bowel series was performed. The radiographs demonstrated characteristic findings of Ascaris lumbricoides infestation. Although the prevalence, diagnosis, and subsequent treatment of an acute abdomen secondary to Ascaris lumbricoides infestation is commonly seen in developing countries, clinicians in developed countries may not consider this entity when faced with a patient with similar symptoms. We frequently care for immigrants from developing countries and our own citizens who visit the countries where ascariasis is endemic. Therefore, heightened awareness of Ascaris lumbricoides infection (ALI) presenting as an acute abdomen is necessary. The diagnosis requires an experienced radiologist and knowledge by the clinician of treatment options and of when a surgeon should be involved.

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 a common parasite and the most serious and dramatic presentation is hepatobiliary and pancreatic ascariasis (HPA). Therefore, this study was planned prospectively to elucidate the clinical presentation of HPA and evaluate the efficacy and safety of endoscopic intervention. In this study we documented 77 consecutive patients with HPA from January 2000 to November 2005. All the patients had endoscopically proven HPA. A total of 77 patients were included in the study. The age ranged from 6 to 80 years, with the third decade most commonly (28.6%) affected. Females were 6 times more likely to be affected than males. The commonest presentation was biliary colic (97.4%); other presentations were acute cholangitis (15.6%), obstructive jaundice (9.1%), acute pancreatitis (6.5%), choledocholithiasis (6.5%), acute cholecystitis (6.5%) and liver abscess (2.6%). In this report 51 (66.2%) had living, 10 (13%) had dead and 16 (20.8%) had both living and dead worms. Choledocholithiasis was associated only with dead worms. From one to 23 worms were found in the biliary tree. In 94.8% of cases we had to remove the worm by wide papillotomy followed by basket extraction. We did not experience any major complications during or following the procedures. Three patients had recurrent HPA during the course of follow-up (1 to 12 months). The majority of patients with HPA presented with biliary colic. This should be kept in mind in the management of an acute abdomen, especially in tropical countries. Endoscopic extraction is a safe and effective procedure for the treatment of HPA.

Ascaris lumbricoides is one of the most common helminthic diseases worldwide and it can cause various complications. The presence of this worm in the biliary tree, however, is a rare condition, especially in children. We describe a child with biliary ascariasis who was presenting clinical symptoms mimicking surgical acute abdomen. The diagnosis was made by ultrasound. The child was successfully treated with mebendazole and anti-spasmolytic. Biliary ascariasis should be added to the differential diagnosis of acute abdominal pain in patients, even in children, from endemic areas.

Ascaris infestation in the gastrointestinal tract is well known in Asian countries. It can be asymptomatic or can present with symptoms of acute abdomen. Perforation and torsion with gangrene are its very rare fatal complications but an important cause of mortality in children. Although ascariasis is very rare in developed countries, clinicians should consider this potentially dangerous, yet treatable, infection in the differential diagnosis of acute abdomen. We herein report a series of five cases of intestinal gangrene secondary to extensive infestation by Ascaris lumbricoides in children aged 1-4 years.

Due to the anatomical characteristics of the biliary tract, Ascaris lumbricoides rarely settles in the gallbladder, which makes biliary ascariasis a rare clinical condition. Ultrasonography plays a significant and practical role in the diagnosis and follow-up of suspected cases of biliary ascariasis. The 15-year-old case presented herein had been complaining of abdominal pain and dyspepsia for three months, and the clinical and laboratory findings for the patient indicated acute abdomen. Abdominal ultrasonography showed worms consistent with Ascaris inside a normal-sized gallbladder, dilated choledochus and the pancreatic duct. We started antiparasitic treatment in the patient, with cholangitis and pancreatitis diagnoses. Post-treatment follow-up ultrasonography showed a normal gallbladder, choledochus and pancreatic duct.

Ascariasis can have various clinical presentations. We present three cases of ascariasis in pregnant or postpartum women, presenting with acute abdomen. The diagnosis of ascariasis was made clinically with the passage of ascaris worms in the vomitus or stool and was supported by ultrasonography. All three patients were treated successfully using anthelmintics. One patient underwent exploratory laparotomy.
