Comparison of endoscopic retrograde cholangiopancreatography with laparoscopic surgery for patients with mild and moderately severe acute biliary pancreatitis

Abstract

Acute biliary pancreatitis (ABP) is an acute inflammatory reaction that occurs as a result of abnormal reflux of bile into the pancreatic duct, which activates pancreatic digestive enzymes to produce pancreatic auto-digestion. ObjectivesTo explore the advantages of Endoscopic Retrograde Cholangiopancreatography (ERCP) treatment compared with laparoscopic surgery in the management of patients with mild and moderately severe ABP, and to study the risk factors for recurrence of ABP and construct a risk prediction model to assist in resolving clinical decision-making and improving prognosis. MethodsPatients with mild and moderately severe ABP treated at General Hospital of Ningxia Medical University from January 1, 2019 to July 1, 2022 were reviewed. A total of 327 patients were enrolled according to the inclusion criteria and exclusion criteria. According to the different treatment modalities, they were divided into the group treated via ERCP (n = 239) and the group treated via laparoscopic surgery (n = 88). Statistical analyses were performed to compare the differences between the average levels of preoperative and postoperative blood routine and blood biochemical indexes, as well as the time of recovery from clinical symptoms, length of hospital stay, and postoperative complications between the two groups of patients. The 280 patients who participated in the follow-up were divided into the recurrence group (n = 130) and the non-recurrence group (n = 150) according to whether they had recurrence or not. Independent samples t-test and binary logistic regression were used to analyze the causative monofactors and risk factors of recurrent biliary pancreatitis, and then to construct the model and assess the predictive accuracy of the model. ResultsOn postoperative day 2, the incidence of local complications, Balthazar CT score, and the number of analgesia were lower in the patients in the group treated by ERCP than in the group treated by laparoscopic surgery (P < 0.001), and the duration of antibiotics, enzyme-suppressing medication, fasting, and hospital stay were shorter in the patients in the group treated by ERCP than in the group treated by laparoscopic surgery (P < 0.001). Personal history, gamma glutamyl transpeptidase (GGT), and treatment modality are risk factors for recurrence of biliary pancreatitis. The model constructed by combining GGT, personal history, and treatment modality had the best predictive ability for disease recurrence compared with the model with GGT, personal history, and treatment modality alone (area under the ROC curve 0.815). ConclusionCompared with the laparoscopic surgery group, ERCP treatment can effectively relieve symptoms and restore gastrointestinal function in advance in patients with ABP, and reduce hospitalisation time and related complications. Personal history, GGT, and treatment modality are risk factors for recurrence of biliary pancreatitis. Patients can prevent recurrence by abstaining from smoking and alcohol, eating a healthy diet, and exercising appropriately.
