Strongyloides stercoralis is an intestinal helminth of systemic distribution, which, once in its host, has the ability to perpetuate itself through an autoinfection cycle, leading to chronic infection. In healthy hosts, the parasite usually does not cause any symptoms, or only mild symptoms that are limited mainly to the small intestine. However, in immunocompromised hosts, uncontrolled multiplication with massive infection may occur, causing hyperinfection syndrome or disseminated strongyloidiasis, which are both associated with high morbidity and mortality. There are few reports of gastric involvement, particularly presenting as ulcer in the stomach. We report a case of gastric ulcer caused by S. stercoralis in HIV-infected patient.

Introduction: Laparoscopic distal pancreatectomy (LDP) has the advantages of reduced blood loss, shorter hospital stays, and a better postoperative quality of life compared with open distal pancreatectomy (ODP). Meanwhile, spleen-preserving laparoscopic distal pancreatectomy is the preferred technique for low-grade malignant and benign tumors located in pancreatic body and tail, since it preserves the immune function of the spleen. The splenic-vessel-preserving (SVP) Kimura technique and splenic vessel resection Warshaw technique are the two primary procedures.
