title: Perioperative and postoperative outcomes of perforated diverticulitis Hinchey II and III: open Hartmann's procedure vs. laparoscopic lavage and drainage in the elderly.
abstract: Hartmann's procedure (HP) is the most performed technique for acute diverticulitis. Laparoscopic lavage and drainage (LLD) is an option evaluated as definitive treatment for diverticulitis Hinchey grade II-III. Aim of the study is to analyze and compare LLD vs HP outcomes. From January 1st 2009 and December 31st 2012 we prospectively enrolled 30 patients with diagnosis of acute diverticulitis Hinchey grade II-III. Fourteen patients underwent to LLD (LLD group, LLDG) and 16 patients to HP (Hartmann group, HG). We evaluated: demographic variables, comorbidities, admission clinical status, radiological imaging, intraoperative outcomes (operative time), postoperative outcomes (admission to ICU, timing of drainage removal, restore of bowel functions, timing of oral solid intake), mortality rate (perioperative and after 12 months) and morbidity rate (surgical, infectious, cardiovascular, renal and systemic complications). Exclusion criteria were: other diseases, colon cancer's suspect or diagnosis, conversion to HP. Patients' mean age was 64.8 years in HG and 62.6 in LLDG. M:F ratio was 6:10 in HG, 8:6 in LLDG. Data showed improved outcomes in LLDG for: total operative time (p < 0.0001), admission to ICU (p 0.0447), restoration of bowel functions (p 0.0035 for gases, p 0.0152 for feces), mobilization (p 0.0087) and length of hospital stay (p 0.0132). According to literature, LLD is related to operative risk, morbidity and mortality rate and length of stay lower than HP. LLD also gives the possibility to avoid stoma. Despite limits of our study, we consider LLD as a "safe and effective" treatment for Hinchey grade II-III acute diverticulitis.
