Laparoscopic-lavage Observational Study (LLOS)
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.
Study Overview
Detailed Description
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.
This "ad hoc" registry will allow centers to retrospectively fill in the data of their patients; the information will be obtained from existing records, diagnostic tests and surgical intervention descriptions. Data will be collected and recorded by all institutions through a specific online shared system.
To facilitate and standardize data collection through a shared database and to ensure the safety of sensitive data, a special online computerized web system has been developed.
Investigators have to provide the required data as fully as possible; however, the lack of certain data does not preclude from sending the remaining data.
Specific aims
- Analyze general outcome
- Analyze the different techniques of laparoscopic lavage
- Analyze the different inclusion criteria
- Analyze the different follow-up
Primary outcome for this retrospective observational study is:
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 outcomes are:
- conversion to any form of laparoscopy different from peritoneal lavage (with or without bowel resection)
- conversion to laparotomy (with or without bowel resection)
- 30 days post-operative mortality;
- 30 days post-operative surgical re-interventions rate;
- 30 days post-operative percutaneous drainage rate;
- hospital readmission rate for recurrence of diverticulitis;
- - rate of visualisation of colonic perforation during laparoscopic peritoneal lavage;
- surgical strategies used in case of detection of a colonic perforation;
- consistency, if any, of visceral adhesiolysis performed during the procedure;
- duration of follow-up
- post-lavage elective resection rate (lavage "bridge" to resection)
Eligibility Each patient is required to meet all of the inclusion criteria and none of the exclusion criteria.
Inclusion criteria Patients with colonic diverticulitis submitted to laparoscopic lavage
Exclusion criteria Patients with occasional finding of colo-rectal cancer
