“…Jaundice owing to reflex spasm of the sphincter of Oddi that is caused by S. stercoralis infection is rare, and it can also occur in Crohn's disease (12). Yoshida et al reported a unique case of a patient with S. stercoralis hyperinfection who showed regurgitation of the contrast medium into the biliary and pancreatic duct in a barium meal study (13). Reports on papillary obstruction in jaundice due to S. stercoralis infection are very rare.…”

<i>Strongyloides stercoralis</i> Infection Causing Obstructive Jaundice and Refractory Pancreatitis: A Lesson Learned from a Case Study

A 58-year-old Japanese woman came to our institution because of leg edema and abdominal distention. She had developed acute pancreatitis 5 times in the past 3 years. Dilation of the bile duct and main pancreatic duct without obstruction was observed on computed tomography and magnetic resonance cholangiopancreatography. The presence of Strongyloides stercoralis was highly suspected from the biopsy sample from the duodenal papilla. Polymerase chain reaction amplification and sequencing of small subunit rDNA from paraffin-embedded specimens identified the worm as S. stercoralis. All of the symptoms were considered to be associated with S. stercoralis infection. Therefore, the patient was treated with oral administration of ivermectin. Subsequently, symptoms and laboratory data improved. There has been no recurrence of the symptoms to date.

“…S. stercoralis is mainly found in the duodenum, including the duodenal papilla, where the larvae mature into adult female parasites and induce varied patterns of inflammatory reactions. Biliary manifestations of strongyloidiasis are rare; however, some reports have described mechanical obstruction of the duodenal papilla and involvement of the bile ducts secondary to strongyloidiasis (Hokama et al 1998;Delarocque Astagneau et al 1994;Hennequin et al 1991;Dearden et al 2004;Penalba et al 1983;Yoshida et al 1981). In the present study, S. stercoralis larvae in the bile were found in one case.…”

Infectious agents, including parasites, often have oncogenic potential. However, there has been no study on the association between Strongyloides stercoralis infection and cancer risk. Therefore, we investigated the relationship between S. stercoralis infection and the occurrence of hepato-pancreato-biliary cancer. This case-control study examined 1,654 patients aged>or=50 years in the Department of Medicine and Therapeutics, Ryukyu University Hospital, Okinawa, Japan, between 1991 and 2005. There were 196 patients with hepato-pancreato-biliary cancer and 1,458 control patients without cancer. The association between S. stercoralis infection and cancer was analyzed by logistic regression analysis adjusted for human T cell lymphotropic virus type 1 infection, age, and sex. The prevalence of S. stercoralis infection in controls and biliary tract cancer was significantly different at 7.5 and 18.4%, respectively (P=0.03, adjusted odds ratio 2.7, 95% confidence intervals 1.1-6.3). In conclusion, our study indicates that the prevalence of S. stercoralis infection in patients with biliary tract cancer appears significantly higher than that in control patients. Thus, we propose that S. stercoralis infection is a risk factor for biliary tract cancer.

“…Changes in host-parasite relationship, especially in older patients, convert the chronic asymptomatic parasitosis into a debilitating and even lethal infection. In addition, patients who are on immunosuppressive therapy and steroids are likely to develop clinical evidence of the infestation [1,4].…”

Nine patients with radiological changes due to Strongyloides stercoralis (SS) are described. A wide variation in appearance exists ranging from mild edema of the duodenal and small bowel mucosa to grossly enlarged, prominent valvulae conniventes. Small bowel dilatation is significant, and in overwhelming infestation toxic dilatation with paresis results. Spasm, ulceration, and stricture are encountered in addition. The appearances usually improve and reverse with treatment. Ampullary involvement is responsible for reflux of barium into the pancreatic duct and biliary tree through a patulous sphincter. In 1 patient the colonic changes resembled ulcerative colitis.
