Successful treatment of large adenoma extending close to the papilla in the duodenum by laparoscopy-assisted pancreas-sparing duodenectomy.

A 54-year-old man had a 65-mm infrapapillary, circular, and laterally spreading tubular adenoma in the distal second and proximal third parts of the duodenum. The papilla was 15 mm from the proximal margin of the tumor. Because the patient requested organ-preserving laparoscopic surgery, we conducted laparoscopy-assisted pancreas-sparing duodenectomy (LAPSD). LAPSD consists of five major procedures: (i) laparoscopic wide Kocher maneuver and transection of the proximal jejunum; (ii) laparoscopic separation of the duodenum from the pancreas; (iii) creation of a small upper median laparotomy; (iv) extracorporeal completion of the segmental duodenectomy; and (v) extracorporeal intestinal reconstruction. The postoperative course was uneventful, and the patient was discharged on postoperative day 8. Histopathological examination revealed that the circumferential margin of the specimen was negative for tumor cells. LAPSD provided a clear margin without damaging the papilla and eliminated the possibility of peritoneal or port-site seeding of tumor cells because part of the procedure was performed extracorporeally. LAPSD is a useful alternative to pancreatoduodenectomy in patients with a large adenoma extending close to the papilla in the duodenum.

Laparoscopy-assisted transduodenal excision of superficial non-ampullary duodenal epithelial tumors.

INTRODUCTION: Transduodenal excision (transduodenal submucosal dissection) is an alternative to pancreaticoduodenectomy for the treatment of benign and low-grade malignant tumors of the duodenum. However, laparoscopic transduodenal excision or laparoscopy-assisted transduodenal excision (LATDE) of such tumors has been rarely reported. In this paper, we present the preliminary results of LATDE in patients with superficial non-ampullary duodenal epithelial tumors. METHODS: Three patients with superficial non-ampullary duodenal epithelial tumors (mucosal adenocarcinoma, n = 1; tubular adenoma, n = 2) underwent LATDE. LATDE consists of four major procedures: (i) laparoscopic wide Kocher maneuver (mobilization of the pancreaticoduodenum); (ii) extracorporeal approach to the fully mobilized duodenum through the upper median longitudinal incision (4 cm in length); (iii) tumor excision by submucosal dissection under direct vision through longitudinal duodenotomy (4 cm in length); and (iv) hand-sewn closure of the mucosal defect and duodenotomy. RESULTS: LATDE was successfully carried out without any intraoperative or postoperative adverse events. The mean operating time and estimated blood loss were 155 min and 17 mL, respectively. Contrast roentgenography on postoperative day 4 showed neither duodenal deformity nor disturbance of gastroduodenal emptying in any of the patients. CONCLUSIONS: LATDE could eliminate the possibility of peritoneal or port-site seeding of tumor cells because the duodenotomy and tumor excision are performed extracorporeally. The meticulously hand-sewn closures of the mucosal defect and duodenotomy can minimize the possibility of postoperative hemorrhage and/or anastomotic leakage. LATDE is a feasible, safe, and minimally invasive treatment for patients with superficial non-ampullary duodenal epithelial tumors that have no risk of lymph node metastasis in the first and second portions of the duodenum.
