Pancreas-sparing duodenectomy with regional lymph node dissection for early-stage ampullary carcinoma: A case control study using propensity scoring methods.

AIM: To investigate the outcomes of pancreas-sparing duodenectomy (PSD) with regional lymph node dissection vs pancreaticoduodenectomy (PD).

METHODS

Between August 2001 and June 2014, 228 patients with early-stage ampullary carcinoma (Amp Ca) underwent surgical treatment (PD, n = 159; PSD with regional lymph node dissection, n = 69). The patients were divided into two groups: the PD group and the PSD group. Propensity scoring methods were used to select patients with similar disease statuses. A total of 138 matched cases, with 69 patients in each group, were included in the final analysis.

RESULTS

The median operative time was shorter among the patients in the PSD group (435 min) compared with those in the PD group (481 min, P = 0.048). The median blood loss in the PSD group was significantly less than that in the PD group. The median length of hospital stay was shorter for patients in the PSD group vs the PD group. The incidence of pancreatic fistula was higher among patients in the PD group vs the PSD group. The 1-, 3-, and 5-year overall survival and disease-free survival rates for patients in the PSD group were 83%, 70%, 44% and 73%, 61%, 39%, respectively, and these values were not different than compared with those in the PD group (P = 0.625).

CONCLUSION

PSD with regional lymph node dissection presents an acceptable morbidity in addition to its advantages over PD. PSD may be a safe and feasible alternative to PD in the treatment of early-stage Amp Ca.
