ABSTRACT
The patient was an 85-year-old man who received chemotherapy with gemcitabine for 2 years 9 months under the diagnosis of unresectable locally advanced pancreatic body and tail cancer. He visited our hospital because of anorexia, upper abdominal fullness, and vomiting. A CT scan showed severe stenosis in the third portion of the duodenum, which was associated with the direct invasion of the advanced pancreatic cancer. Upper gastrointestinal fiberscopy revealed a severe duodenal obstruction; however, pancreatic cancer exposure within the duodenal mucosa was not observed. As the stenosis of the duodenum was relatively smooth because of the cancer invasion into only the submucosa, deviation of the metallic stent was possible, so we performed laparoscopic gastrojejunostomy. We started the surgery with 5-port settings. A slit was made in the gastric body by using ENDO-GIA®, and bypass surgery with a Roux-en-Y anastomosis was performed. The postoperative course was good, and oral intake resumed on the third postoperative day. Thereafter, he could leave the hospital with good progress and received systemic chemotherapy using gemcitabine. In the present case, an extramural gastrointestinal stenosis without cancer that was not exposed in the gastrointestinal mucosa was poorly fixed with gastrointestinal metallic stents and use of a deviating metallic stent was reported, so we chose laparoscopic gastrojejunostomy. In addition, after undergoing laparoscopic surgery, which is a minimally invasive treatment, he recovered quickly and shifted early to systemic chemotherapy. Herein, the usefulness of laparoscopic gastrojejunostomy for extramural stenosis is reported with a review of related literature.
