[A Case of Laparoscopic Surgery for Malignant Lymphoma of the Small Intestine with Bowel Obstruction].

An 80-year-old woman presented to our hospital complaining of nausea and abdominal distention. An abdominal computed tomography scan revealed wall thickening of the small intestine, a dilated oral intestinal tract, swollen intra-abdominal lymph nodes, and splenomegaly. Moreover, the soluble interleukin-2 receptor level was increased at 2,120 U/mL. Accordingly, we diagnosed the patient with a small bowel obstruction due to malignant lymphoma of the small intestine, for which we performed a laparoscopy-assisted partial resection of the small intestine after decompression. The resected specimen was pathologically diagnosed as diffuse large B-cell lymphoma. The patient's general condition recovered rapidly after laparoscopic surgery, and her clinical course proceeded smoothly to the initiation of chemotherapy(R-CHOP)at the Department of Hematology. The tumor remains in remission now. Here, we report a case of laparoscopic surgery for malignant lymphoma of the small intestine that caused bowel obstruction due to luminal narrowing along with a relevant literature review.
