The purpose of this study is to collect a multi-institutional database including all relevant data regarding the surgical and clinical features of patients underwent to laparoscopic lavage for complicated colic diverticulitis. The main objectives are:

  • To determine the surgical and clinical outcomes, in the short and long term.
  • To compare results according to the different type of techniques, device used and manner of execution of the different surgical steps.
  • To relate results of different surgeries with baseline characteristics of patients and stage of disease.

Condition Intervention
Diverticulitis Procedure: laparoscopic-lavage

Study Type: Observational [Patient Registry]
Study Design: Observational Model: Cohort
Time Perspective: Cross-Sectional
Target Follow-Up Duration: 5 Years
Official Title: Laparoscopic-lavage Observational Study

Further study details as provided by Alberto Arezzo, University of Turin, Italy:

Primary Outcome Measures:
  • success rate [ Time Frame: 12 months ]
    the success rate of laparoscopic peritoneal lavage, defined as the rate of patients alive with no need of further surgical treatment for recurrent attacks of diverticulitis

Secondary Outcome Measures:
  • conversion to any form of laparoscopy [ Time Frame: intraoperative ]
    conversion to any form of laparoscopy different from peritoneal lavage (with or without bowel resection)

  • conversion to laparotomy [ Time Frame: intraoperative ]
    conversion to laparotomy (with or without bowel resection)

  • 30 days post-operative mortality [ Time Frame: 30 days ]
  • 30 days post-operative surgical re-interventions rate [ Time Frame: 30 days ]
  • 30 days post-operative percutaneous drainage rate [ Time Frame: 30 days ]
  • hospital readmission rate for recurrence of diverticulitis [ Time Frame: 30 days ]
  • visualisation of colonic perforation [ Time Frame: intraoperative ]
    rate of visualisation of colonic perforation during laparoscopic peritoneal lavage

  • visceral adhesiolysis [ Time Frame: intraoperative ]
    consistency, if any, of visceral adhesiolysis performed during the procedure

  • duration of follow-up [ Time Frame: 12 ]
  • post-lavage elective resection rate (lavage "bridge" to resection) [ Time Frame: 12 months ]
