Study: NCT05942209

Intervention type: DIAGNOSTIC_TEST
Intervention: ECO-LEAK transvaginal ultrasound
Description: After performing the colorectal anastomosis, the patient is monitored postoperatively both clinically and analytically, with serial laboratory tests including PCR and procalcitonin. In the absence of symptoms on the 4th to 5th day an ultrasound - ecoenema is performed. First, the Foley catheter is inserted via the transanal route with instillation of 180cc of serum under ultrasound guidance with a probe in the vagina, using a sagittal and midline cut. In case there is the appearance of free pelvic fluid (previously absent) or an increase in free fluid compared to the baseline examination (fluid present at the beginning of the examination) around the anastomosis/pelvic area, the test will be considered positive.

Intervention: ECO-LEAK with CT-Scan or rectoscopy
Description: After performing the colorectal anastomosis, the patient is monitored postoperatively both clinically and analytically, with serial laboratory tests including PCR and procalcitonin. In the absence of symptoms on the 4th to 5th day, a CT scan or rectoscopy is performed, along with an ecoenema.
