ABSTRACT
PURPOSE: Pancreatoduodenectomy is the most common operative procedure performed for distal bile duct carcinoma. Data on outcome after surgery for this rare malignancy is scarce, especially from western countries. The purpose of this study is to explore the prognostic factors and outcome after pancreatoduodenectomy for distal bile duct carcinoma. METHODS: Patients receiving pancreatoduodenectomy for distal bile duct carcinoma were identified from institutional databases of five German and one Russian academic centers for pancreatic surgery. Univariable and multivariable general linear model, Kaplan-Meier method, and Cox regression were used to identify prognostic factors for postoperative mortality and overall survival. RESULTS: N = 228 patients operated from 1994 to 2015 were included. Reoperation (OR 5.38, 95%CI 1.51-19.22, p = 0.010), grade B/C postpancreatectomy hemorrhage (OR 3.73, 95%CI 1.13-12.35, p = 0.031), grade B/C postoperative pancreatic fistula (OR 4.29, 95%CI 1.25-14.72, p = 0.038), and advanced age (OR 4.00, 95%CI 1.12-14.03, p = 0.033) were independent risk factors for in-hospital mortality in multivariable analysis. Median survival was 29 months, 5-year survival 27%. Positive resection margin (HR 2.07, 95%CI 1.29-3.33, p = 0.003), high tumor grade (HR 1.71, 95%CI 1.13-2.58, p = 0.010), lymph node (HR 1.68, 95%CI 1.13-2.51, p = 0.011), and distant metastases (HR 2.70, 95%CI 1.21-5.58, p = 0.014), as well as severe non-fatal postoperative complications (HR 1.64, 95%CI 1.04-2.58, p = 0.033) were independent negative prognostic factors for survival in multivariable analysis. CONCLUSION: Distant metastases and positive resection margin are the strongest negative prognostic factors for survival after pancreatoduodenectomy for distal bile duct carcinoma; thus, surgery with curative intent is only warranted in patients with local disease, where R0 resection is feasible.

BACKGROUND: Laparoscopic pancreatoduodenectomy (LPD) with concomitant resection of major portal vessels has recently emerged as feasible and safe, with similar morbidity and mortality as well as oncologic outcome compared with patients undergoing open PD with major vascular resection. MATERIALS AND METHODS: Of a consecutive series of 133 LPD, eight patients underwent concomitant superior mesenteric vein/portal vein (SMV/PV) resection and reconstruction with the intent of achieving a R0 resection. RESULTS: Four of these eight patients had tangential resection followed by lateral wall repair with Prolene 4.0. One patient had tangential resection with patch reconstruction. Three patients had circular venous resection: One had end-to-end primary venous reconstruction, and two patients had a prosthetic vascular graft interposition. There was no operative mortality. The SMV/PV was patent in all patients postoperatively on ultrasound Doppler or CT scans. Two patients (who underwent circular venous resection) had postoperative complications. One 77-year-old patient with preexisting cardiovascular disease died of heart failure on postoperative day 2, while another (undergoing prosthetic graft reconstruction) had postoperative bilioenteric anastomotic dehiscence and underwent immediate re-laparoscopy for repair. CONCLUSIONS: In our experience, LPD with concomitant major venous resection is feasible even in cases of longitudinal venous invasion. Further studies are needed to evaluate the role of laparoscopy in borderline pancreatic cancer.
