Abstract

Background

Clinically relevant postoperative pancreatic fistula (CR-POPF) is a major source of morbidity after distal pancreatectomy. This study examined the association between postoperative opioid use and CR-POPF in the context of opioid-sparing postoperative care.

Methods

A case–control study was performed on consecutive patients who underwent distal pancreatectomy between October 2016 and April 2022 at a single institution. Patients who developed CR-POPF were compared to controls. Multivariable regression modeling was used to identify factors associated with CR-POPF.

Results

A total of 281 patients underwent 187 open, 20 laparoscopic, and 74 robotic-assisted operations. The rate of CR-POPF was 21% (n = 58). CR-POPF rate declined from 32 to 8% over the study period (p < 0.001). Median oral morphine equivalents (OME) administered on POD 0–1 and 0–3 were 94 and 129 mg, respectively, in patients who did not develop a fistula versus 130 and 180 mg in those who did (both p ≤ 0.001). POD 0–3 OME (OR 1.11, p = 0.044) was independently associated with increased odds of CR-POPF, with each additional 50 mg (equivalent to 10 tramadol pills) increasing the relative risk by 11% and absolute risk by 2%.

Conclusion

Early postoperative opioid use after distal pancreatectomy was associated with increased odds of CR-POPF. Decreasing perioperative opioid use through enhanced postoperative management is a low-cost and generalizable approach that may reduce rates of CR-POPF after distal pancreatectomy.
