BACKGROUND: Superior mesenteric artery (SMA) nerve plexus (PLsma) dissection has been performed to achieve R0 resection in pancreaticoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC) in high-volume centers. However, full-extent PLsma preservation in PD is employed in our institution. The feasibility of the PLsma preservation strategy was investigated.
METHODS: Between January 2010 and December 2020, 156 patients underwent PLsma preservation PD for PDAC at our institution. Of these, 118 patients had resectable PDAC (R group) and 38 patients had borderline resectable artery (BR-A group). Clinical and oncological outcomes focusing on local recurrence, patient prognoses, and morbidities (including postoperative refractory diarrhea) were retrospectively analyzed and our postoperative outcomes were compared with those of other institutions.
RESULTS: Pathological R0 resection by PLsma preservation PD was achieved in 96 R group patients (81.4%) and 27 BR-A group patients (71.1%). The median postoperative hospital stay was 15.0 days in both groups. Local site-only recurrence was observed in 10.2% (12/118) of R-group and 10.5% (4/38) of BR-A-group patients, whereas distant site-only recurrence occurred in 21.2% (25/118) of R-group and 28.9% (11/38) of BR-A-group patients. Median survival times were 64.3 months (R group) and 35.4 months (BR-A group, p = 0.07). Median disease-free survival (DFS) times were 31.0 months (R group) and 12.0 months (BR-A group). No diarrhea requiring opioids was observed in either group. These results were equal or superior to those of PLsma dissection PD in other institutions.
CONCLUSIONS: PLsma preservation in PD was feasible compared to PLsma dissection in recurrence and overall survival.
