HPA is caused by invasion and migration of nematode,Ascaris lumbricoides,in to the biliary tract and pancreatic duct. Patients present with biliary colic,cholangitis,cholecystitis,hepatic abscesses and acute pancreatitis. Ascarides traverse the ducts repeatedly,get trapped and die,leading to formation of hepatolithiasis. HPA is ubiquitous in endemic regions and in Kashmir,one such region,HPA is the etiological factor for 36.7%,23%,14.5% and 12.5% of all biliary diseases,acute pancreatitis,liver abscesses and biliary lithiasis respectively. Ultrasonography is an excellent diagnostic tool in visualizing worms in gut lumen and ductal system. The rational treatment for HPA is to give appropriate treatment for clinical syndromes along with effective anthelmintic therapy. Endotherapy in HPA is indicated if patients continue to have symptoms on medical therapy or when worms do not move out of ductal lumen by 3 wk or die within the ducts. The worms can be removed from the ductal system in most of the patients and such patients get regression of symptoms of hepatobiliary and pancreatic disease.展开更多

Heavy worm loads mainly due to untreated worm infestations are often associated with increased risk of severe sequelae. We report the first complicated case of A. lumbricoides causing small bowel obstruction in a 9-year-old boy that necessitated surgical intervention on a tropical island in the Indian Ocean, where cases of Ascariasis are rarely encountered.展开更多

In some rare cases,ascariasis may cause serious consequences even sudden death. This study was undertaken to review the life-threatening complications of ascariasis in trauma patients reported in the literature.DATA SOURCES:Relevant articles about ascariasis and trauma were searched from Pubmed,Google scholar,Scirus,and Wanfang databases.RESULTS:Twenty-four patients with ascariasis were collected from 21 articles searched. Most of these patients were from tropical and subtropical countries. Of the 24 patients,12 were children. Their major complications occurred in the airway passage and digestive tract. There were 3 fatal cases in these patients. Twelve of the 24 patients described in 10 articles were reported in the last 10 years.CONCLUSIONS:Early diagnosis and prompt intervention are essential to minimize the high morbidity and mortality of these serious complications in trauma patients. Physicians should be aware of the possibility of Ascaris infection in a trauma patient from endemic area of ascariasis. History of Ascaris infection and routine examination of feces for Ascaris eggs may be helpful to make a correct diagnosis.展开更多

Infection can lead to various complications because it can spread along the gastrointestinal tract. Although A. lumbricoides infection is a serious healthcare issue in developing countries, it now also has a worldwide distribution as a result of increased immigration and travel. Intestinal obstruction is the most common complication of A. lumbricoides infection, potentially leading to even more serious consequences such as small bowel perforation and peritonitis. Diagnosis is based primarily on stool samples and the patient's history. Early diagnosis, aided in part by knowledge of the local prevalence, can result in early treatment, thereby preventing surgical complications associated with intestinal obstruction. Further, delay in diagnosis may have fatal consequences. Capsule endoscopy can serve as a crucial, non-invasive diagnostic toolfor A. lumbricoides infection, especially when other diagnostic methods have failed to detect the parasite. We report a case of A. lumbricoides infection that resulted in intestinal obstruction at the level of the ileum. Both stool sample examination and open surgery failed to indicate the presence of A. lumbricoides, and the cause of the obstruction was only revealed by capsule endoscopy. The patient was treated with anthelmintics.展开更多
