Clinical characteristics and outcomes of acute pancreatitis following spinal surgery: a systematic review

Abstract

Objective This study reviewed the current evidence on the clinical characteristics and outcome of acute pancreatitis (AP) following spinal surgery. Methods A systematic search was performed to identify English articles published through May 2020 in PubMed, Scopus, EMBASE, Latin American & Caribbean Health Sciences Literature, and Cochrane Library. Data on clinical characteristics, risk factors, and outcomes were analyzed. Results Eleven papers (including six case reports) were included, with 306 patients (incidence, 23.0%) developing AP after spinal surgery (mean age, 14.2 years). Of the studies that specified symptoms (55 patients), abdominal pain (43.6%), nausea and vomiting (32.7%), and abdominal distension (7.27%) were most prevalent. The mean duration from surgery to symptom onset was 6.15 days (range, 1–7). The most common complications of AP were glucose intolerance (25%), peritonitis (2%), pseudocyst formation (2%), and fluid collection (2%) were most prevalent. Prolonged fasting time (13.6%), intraoperative blood loss (9.09%), gastroesophageal reflux disease (9.1%), age >14 years (9.1%), and low BMI (9.1%) were most commonly associated with AP. Two deaths (0.6%) were reported. Conclusion AP remains an important complication of spinal surgery because of its morbidity and mortality. Avoiding major risk factors can reduce the incidence of AP following spinal surgery.
