Role of CT Angiography With Three-dimensional Reconstruction of Mesenteric Vessels in Planning and Performing of Laparoscopic Colorectal Resections

Phase 3

Completed

• Conditions: Colorectal Laparoscopic Resection
• Interventions: Procedure: Laparoscopic Right Hemicolectomy; Procedure: Laparoscopic Left Hemicolectomy; Procedure: Anterior Rectal Resection

• Registration Number: NCT01540448
• Lead Sponsor: University of Roma La Sapienza

Brief Summary

The aim of this study is to evaluate if the prior knowledge of the individual mesenteric vascular anatomy of patients represents an advantage in performing laparoscopic colorectal resections. The investigators want demonstrate that the three-dimensional reconstruction of colonic vascular anatomy, acquired with a CT angiography, may lead to a more effective and less extensive dissection and to a fewer intraoperative and postoperative complications.

Arm && Interventions

Group	Intervention	Description
No-3DCT	Laparoscopic Right Hemicolectomy	All patients were subjected to a CT scan with 3D mesenteric angiography but the surgeon was able to view the 3D reconstruction only after surgery.
No-3DCT	Laparoscopic Left Hemicolectomy	All patients were subjected to a CT scan with 3D mesenteric angiography but the surgeon was able to view the 3D reconstruction only after surgery.
No-3DCT	Anterior Rectal Resection	All patients were subjected to a CT scan with 3D mesenteric angiography but the surgeon was able to view the 3D reconstruction only after surgery.
3DCT	Laparoscopic Right Hemicolectomy	All patients were subjected to a CT scan with 3D mesenteric angiography and the surgeon was able to view 3D reconstruction before and during laparoscopic colorectal resection.
3DCT	Laparoscopic Left Hemicolectomy	All patients were subjected to a CT scan with 3D mesenteric angiography and the surgeon was able to view 3D reconstruction before and during laparoscopic colorectal resection.
3DCT	Anterior Rectal Resection	All patients were subjected to a CT scan with 3D mesenteric angiography and the surgeon was able to view 3D reconstruction before and during laparoscopic colorectal resection.

Primary Outcome Measures

Name	Time	Method
Surgical Performance (operative time)	within the first 4 hours	The consequences on the surgical performance of preoperative knowledge of the mesenteric vascular anatomy assessed by the evaluation of the operative time

Secondary Outcome Measures

Name	Time	Method
complex identification of mesenteric vessels performing laparoscopic colorectal resection	within the first 4 hours
Iatrogenic vascular or visceral injuries	within the first 10 postoperative days	Iatrogenic vascular or visceral injuries related to difficult identification of right anatomy
intraoperative bleeding	within the first 4 hours	intraoperative bleeding related to dissection for mesenteric vessels quest. Blood loss of less than 20 mL was considered mild; between 20 and 100 mL, moderate; and more than 100 mL, severe.
Postoperative complications	within the first 15 postoperative days
lymph nodes harvesting	within first 4 hours	number harvested of lymph nodes
Anatomical variations of mesenteric vessels	Within 24 hours before surgical procedure	anatomical variations of mesenteric vessels detected by peroperative CT scan
