Abstract Background: Longitudinal pancreatojejunostomy with partial pancreatic head resection (the Frey procedure) is accepted for surgical treatment of painful chronic pancreatitis. However, conduct and reporting are not standardized and thus, making comparisons difficult. This study assesses the reporting standards of this procedure.
Data sources: A systematic literature review was performed between January 1987 and January 2020. The keyword and Medical Subject Heading “chronic pancreatitis” was used together with the individual operation term “Frey pancreatojejunostomy”. Reports were included if they provided original information on conduct and outcome. Thirty-three papers providing information on 1205 patients constituted the study population. Risk of bias in included reports was assessed.
Results: Etiology of chronic pancreatitis (alcohol) was reported in 26 of 28 (93%) studies, duration of symptoms prior to surgery in 19 (58%) studies and preoperative opiate use in 12 (36%) studies. In terms of morphology, pancreatic duct diameter was reported in 17 (52%) studies and diameter of the pancreatic head in 13 (39%) studies. In terms of technique, three (9%) studies reported weight of excised parenchyma. There were 9 (0.7%) procedure-related deaths. Post-operative follow-up ranged from 6 to 82.5 months. No studies reported post-operative portal hypertension.
Conclusions: There is substantial heterogeneity between studies in reporting of clinical baseline, morphology of the diseased pancreas, operative detail and outcome after longitudinal pancreatojejunostomy with partial pancreatic head resection. This critically compromises the comparison between centers and between surgeons. Structured reporting is necessary for clinicians to assess choice of procedure and for patients to make informed choices when seeking treatment for painful chronic pancreatitis.
