[A Case of Intussusception in the Jejunum Due to Small Intestinal Adenocarcinoma].

ABSTRACT

The patient was a woman in her 60's with an 11-month history ofpersistent epigastralgia and abdominal distension, without abnormal findings on upper endoscopy, abdominal ultrasonography, and abdominal computed tomography in other hospitals. She presented to our hospital with a complaint off requent vomiting; abdominal CT indicated intussusception in the jejunum due to a small intestinal tumor, and laparoscopic exploration and partial jejunectomy were performed. The histopathological diagnosis was tub1>tub2>pap, pT4(SE), pN1, pPM0, pDM0, pStage III A. She was treated with oral chemotherapy( S-1)and developed no recurrence 7 months after surgery. Laparoscopic exploration was useful to detect intussusception in the jejunum due to small intestinal adenocarcinoma.
