[A Case of a Single Incisional Laparoscopic Assisted Partial Jejunectomy Performed to Treat a Primary Small Intestine Cancer in a Young Woman].

A 35-year-old woman was followed by epilepsy therapy. She was admitted to our hospital because of a 15 kg decrease in weight, bilious vomit, and frequent epileptic seizures because she could not take oral antiepileptic drugs. A primary small intestinal cancer was suspected in the jejunum about 100 cm from the incisor by single-balloon enteroscopy. A single incisional laparoscopic assisted partial jejunectomy that was minimally invasive was performed to improve the symptoms of intestinal obstruction. The histopathological diagnosis was moderately differentiated adenocarcinoma, ly0, v1, pT4(SE), pN0, pM0, pStage II B. A primary small intestinal cancer is a relatively rare disease, accounting for 0.3-1.0%ofall cancers ofthe digestive tract. The primary method oftreatment is surgery, and understanding the positional relationship ofthe tumor is important when performing surgery because most primary small intestinal cancers are located in the vicinity ofthe ligaments ofTreitz. We present a case in which safe and minimally invasive surgery was performed to treat a primary small intestinal cancer in a young woman with intractable epilepsy and a significant decrease in ADL for intestinal obstruction, along with a review of the literature.
