Surgical treatment and outcome for primary duodenal adenocarcinoma. Single center experience

In this study, we aimed to evaluate patients who underwent curative surgical treatment for primary duodenal adenocarcinoma and to present our experience.

Patients diagnosed with primary duodenal adenocarcinoma between 2006 and 2018 participated in the study. The demographic and clinical characteristics of the patients, details of the operation, pathological features of the tumors, short- and long-term follow-up results, and mean survival were evaluated retrospectively.

Nine patients with a mean age of 54.7 participated in the study. 55% of the patients were male. The most common presenting symptom was abdominal pain (n: 6; 67%). The most common tumor localization was D2-3 (n: 7; 78%), and the most common surgical operation was pancreaticoduodenectomy (n: 7; 78%). There were no intraoperative complications in any patient. The mean tumor diameter was 3.5 cm. The mean number of lymph nodes dissected was 8.3 and the mean number of metastatic lymph nodes was 2. The most common postoperative complication was pancreatic fistula (n: 3; 33%). The mean length of stay was 21.8 days. One patient developed septic shock and mortality happened within the 30-day period. The most common cause of unplanned admission to the hospital within 90 days was wound infection (n: 2; 22%). One patient developed local recurrence and two patients had systemic metastasis. We found an average survival of 40 months.

Pancreaticoduodenectomy is the most common approach in its curative surgery and it has a long survival despite the high postoperative complication rate. We recommend radical resection in the surgical treatment of primary duodenal adenocarcinoma.
