Objective To describe patient characteristics and outcomes after duodenal repair during postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) and to identify treatment and management patterns. Methods The Indiana University Testis Cancer database was used to identify all patients who underwent simultaneous partial duodenectomy and PC-RPLND from 1983 to 2013. Patient records were reviewed to describe patient and tumor characteristics, type of duodenal restoration, postoperative management, and complications. Results Of the 2223 PC-RPLND performed during the study period, we identified 39 patients who underwent simultaneous duodenectomy, with 1 patient requiring 2 duodenal procedures for a total of 40 duodenal procedures. The postchemotherapy median tumor mass size was 8.95 (2.5-17) cm. Fifty percent of cases were standard PC-RPLND; the remainders were redo, desperation, or late relapse cases. Preoperative gastrointestinal symptoms were present in 21% of patients and included bowel obstruction (8%) or gastrointestinal bleeding (13%). Retroperitoneal pathology consisted of teratoma (48%), cancer (33%), and necrosis (20%). Duodenal involvement was managed with primary duodenorrhaphy (68%), duodenojejunostomy (18%), duodenoduodenostomy (13%), or pancreaticoduodenectomy (3%). Starting in the year 2000, duodenostomy and gastrostomy tubes were no longer used. The most common postoperative complication was ileus (45%) with a 3% duodenal fistula rate. Conclusion Duodenal tumor involvement during PC-RPLND is most commonly managed with primary duodenorrhaphy after partial duodenectomy with an acceptable duodenal fistula rate. The routine use of duodenostomy or gastrostomy tubes is not recommended.
