Anastomotic Leakage After Right Hemicolectomy for Cancer, a Prospective Multicenter Study of SICO-CC Network

Condition(s) studied

Study summary

This is a nationwide prospective observational study to assess the overall clinical anastomotic leakage rate after right hemicolectomy for cancer, to detect the independent risk factors for AL, and to develop a clinical prediction model to estimates of the probability of the occurrence of an AL after surgery. Since this is a multicenter prospective study, the Division of Surgical Oncology and Digestive Surgery from the University of Turin, Department of Oncology, AOU San Luigi Gonzaga di Orbassano will be the Coordinator Center of the study, Ethics committee approves will be requested before the implementation of this study.

Italian high-volume colorectal surgery centers members of SICO (The Italian Society of Oncological Surgery) have agreed to participate as collaborators of this study, notification and revision from their local ethics committee will be requested as well. A certified general surgeon with a large experience in the preoperative, operative, and postoperative management of patients with colorectal cancer has been identified to coordinate the study in each center. Id information of the potential collaborators is specified in the section "Trial Setting". Once the study is activated, eligible patients (or a representative) must provide written, informed consent before any study procedures occur. No intervention or modification of the habitual clinical practice is planned All data will enter into a database provided by the promoting center. There are three main sections of data collection for each patient:

* Preoperative: baseline, disease and demographics.
* Operative: details about the surgery, anastomosis construction and enterotomy closure.
* Follow-up: outcomes data about the early (within 30 postoperative day) and late postoperative course (31 th - 60th postoperative day) and pathology report. The definition of AL is based on the presence of clinical signs (pain, fever, tachycardia, peritonitis, feculent or enteric drainage, purulent drainage, postoperative ileus, abscess, septicemia, and/or organ failure) with radiographic signs (fluid collections, gas containing collections at CT scan) suggestive of AL and-or intraoperative or autopsy findings (gross enteric spillage, anastomotic disruption). The absence of AL will be assumed by a normal postoperative course and the absence of symptoms suggestive of AL with or without radiologic confirmation.

Eligibility

Primary outcome measure(s)

• overall rate of AL — from 1st to 30th postoperative day
  defined as the total cases of patients with clinical signs or symptoms of AL (pain, fever, tachycardia, peritonitis, feculent or enteric drainage, purulent drainage, postoperative ileus, abscess, septicemia, and/or organ failure), any radiological findings suggestive of AL (fluid collections, gas containing collections at CT scan) or intraoperative or autopsy findings (gross enteric spillage, anastomotic disruption), expressed in percentage. \[time frame: from 1st to 30th postoperative day\]. And identify the main associated factors through a multivariate model regression.
