Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Phase III clinical trial to evaluate the efficacy of the open abdomen as bridging therapy to perform transit reconstruction in patients with anastomotic dehiscence. It is a randomized controlled single-center study that will be carried out at the Virgen del Rocío University Hospital in Seville.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The selected patients will be those patients reoperated for an anastomotic dehiscence (intestinal, ileocolic, colo-colic or colorectal anastomosis) with localized or generalized peritonitis. Those patients with anastomosis in the middle or lower rectum will be excluded. Once selected, if all the inclusion criteria and none of the exclusion criteria are met, the patient (or family members in case the patient does not have a sufficient level of consciousness to understand and accept the information) will be informed in detail of the therapeutic options included in the study as well as their randomization and will sign the informed consent, understanding and accepting all the information.

The patients included in the experimental group will be operated on, performing the resection of the intestinal segment affected by the dehiscence, the sectioned intestinal ends will be left inside the abdomen without anastomosis, and open abdomen with Vacuum Assisted Closure therapy will be established. After surgery, the patient will be cared for in the intensive care unit where resuscitation will be carried out in order to improve the patient's general conditions. After 48 ± 24 hours, a second surgical procedure will be carried out where local conditions will be evaluated in order to decide performing a delayed anastomosis.

The patients included in the control group will be operated on with the resection of affected intestinal segment and a stoma with or without associated mucosal fistula will be performed at the same surgical time. After the procedure, the patient will be cared for in the intensive care unit in order to improve the general conditions of the patient.

The main efficacy variable will be the stoma generation during each of the interventions and the main safety variable will be mortality in both groups. Other secondary variables will be collected, such as: Intensive Care Unit (ICU) stay, need for a non planned re-intervention, early and late complications related to surgery, complications associated with the use of an open abdomen technique.

A descriptive analysis of the quantitative variables will be carried out using the size, means and standard or median deviations and percentiles, the bilateral 95% confidence interval and range (minimum and maximum) or P50 \[P25 - P75\].

The relationship between dichotomous qualitative variables will be studied using the chi-square test, or Fisher's exact statistic if necessary. The effect of each of the treatment groups on the outcome variables will be measured by calculating the relative risk (RR) together with its 95% confidence interval (CI).

In all patients, a follow-up visit will be carried out at one month, at 6 months and at 12 months after surgery in order to evaluate the associated complications and record possible adverse events.

The study will be reviewed and approved by the Seville Provincial Research and Ethics Committee.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention group

The patients included in the experimental group will be operated on, performing the resection of the intestinal segment affected by the dehiscence, the sectioned intestinal ends will be left without anastomosis, and open abdomen therapy will be established. After surgery, the patient will be cared for in the intensive care unit where intensive resuscitation will be carried out in order to improve the general conditions of the patient. After 48 ± 24 hours, a second surgical procedure will be performed where local conditions will be evaluated and the possibility of performing a delayed anastomosis will be evaluated.
