A case of the primary small intestinal cancer which performed operation under laparoscopy after ileus decompression.

The patient was a 66-year-old man with repeated episodes of abdominal pain resulting in a diagnosis of ileus, and he was admitted to this hospital. During hospitalization, the pain symptoms improved after the insertion of an ileus tube, but there was a recurrence of ileus after the patient was started on a liquid diet. An adhesive intestinal obstruction was thus suspected, and laparoscopy was performed. A diagnosis of small intestinal carcinoma was made based on the intraoperative findings. A partial resection of the small bowel and a regional lymphadenectomy were performed through a minor laparotomy. The incidence of primary small intestinal cancer has been relatively rare, and it is difficult to differentiate the disease in most cases. A laparoscopy is considered useful to diagnose and treat ileus after decompression of the intestinal tract, and this article describes the case with some discussion.
