Abstract
BACKGROUND
Surgical resection of intraductal papillary mucinous neoplasms is based on preoperative high-risk stigmata/worrisome features, but the risk of overtreatment remains high. The aim of this study was to evaluate surgical indications and perioperative and long-term complications in patients with low-grade intraductal papillary mucinous neoplasms.
METHODS
Patients who underwent surgical resection between 2009 and 2018 with a final histology of low-grade intraductal papillary mucinous neoplasms were included. Surgical indications, type of surgery, and short- and long-term outcomes were evaluated.
RESULTS
A significant decrease in the rate of patients resected for low-grade intraductal papillary mucinous neoplasms was observed (43.6% in 2009-2012 vs 27.8% in 2013-2018; P = .003), and 133 patients were finally included (62 women, median age: 68 years). Of these, 24.1% had 1 worrisome feature, 39.8% had ≥2 worrisome features, 18.8% had ≥1 high-risk stigmata, and 15.8% had ≥1 worrisome features + 1 high-risk stigmata. Overall surgical morbidity was 55.6%, 15.8% had Clavien-Dindo ≥3 complications, reoperation rate was 3.8%, and 90-day postoperative mortality was 1.5%. After a median follow-up of 60 months, 13 patients (11.5%) had a recurrence of benign intraductal papillary mucinous neoplasm in the pancreatic remnant, and 2 patients (1.8%) developed pancreatic ductal adenocarcinoma. After partial pancreatectomy, 51.3% of patients were taking pancreatic enzyme replacement therapy. Among nondiabetics, 26% developed diabetes after partial pancreatectomy, of which 38% were insulin-dependent. Eighteen patients (13.7%) developed incisional hernia.
CONCLUSION
Given the rates of morbidity and long-term complications after pancreatic resections, surgeons should attentively balance the true risks of intraductal papillary mucinous neoplasm degeneration with the risks of surgical resection in each patient.
