Short- and long-term outcomes for primary anastomosis versus Hartmann's procedure in Hinchey III and IV diverticulitis: a multivariate logistic regression analysis of risk factors.

Purpose: The management of perforated diverticulitis with generalized peritonitis is still controversial and no preferred standardized therapeutic approach has been determined. We compared surgical outcomes between Hartmann's procedure (HP) and primary anastomosis (PA) in patients with Hinchey III and IV perforated diverticulitis.

Methods: Multicenter retrospective analysis of 131 consecutive patients with Hinchey III and IV diverticulitis operated either with HP or PA from 2015 to 2018.
