Abstract
Background
The long-term survival rate of patients with pancreatic ductal adenocarcinoma has improved alongside the development of multidisciplinary treatment, and there is now demand for less invasive surgery that maintains postoperative pancreatic function. We evaluated the efficacy of pancreas-preserving distal pancreatectomy in terms of oncologic parameters and postoperative pancreatic function.
Methods
The data of 98 consecutive patients who underwent distal pancreatectomy for the treatment of pancreatic ductal adenocarcinoma between 2012 and 2022 in our institution were retrospectively analyzed. The surgical outcomes, overall survival, and postoperative pancreatic function were compared between pancreas-preserving distal pancreatectomy, in which the pancreatic stump was distal to the left margin of the portal vein on postoperative computed tomography, and conventional distal pancreatectomy.
Results
Sixteen patients (16%) underwent pancreas-preserving distal pancreatectomy. Fewer lymph nodes were dissected in the pancreas-preserving distal pancreatectomy group than the conventional distal pancreatectomy group (19 vs 31, respectively; P < .01); however, the R0 resection rate (94% vs 93%, respectively; P = 1.00), recurrence-free survival, and overall survival were similar. Similar results were obtained in an analysis limited to patients with pancreatic ductal adenocarcinoma in the pancreatic tail. Patients who underwent pancreas-preserving distal pancreatectomy were less likely to develop worsening of their diabetes than those who underwent conventional distal pancreatectomy (19% vs 39%, respectively; P = .16). Nonalcoholic fatty liver disease newly developed in 22% of the patients who underwent conventional distal pancreatectomy but in none of those who underwent pancreas-preserving distal pancreatectomy (P = .04).
Conclusion
The pancreatic transection site should be distally located to preserve postoperative pancreatic function when R0 resection can be achieved.
