Study Description
Brief Summary:
The study hypothesized that a narrow gastric conduit(less than 3cm in width) would minimize anastomotic leakage following minimally invasive esophagectomy. Therefore we raise this random-controlled research, and investigate the leakage ratio from different widths of gastric conduit formed during the operation.

Condition or disease Intervention/treatment
Anastomotic Leakage Procedure: Narrowed Gastric Conduit Procedure: Widened Gastric Conduit

Detailed Description:
Patients underwent minimally invasive esophagectomy in Zhongshan Hospital of Fudan University will be enrolled and be assigned to wide or narrow gastric conduit group randomly. Intra-operative blood supply and vascular SaO2 will be observed during the operation, and the rate of anastomotic leakage, together with its clinical details will be recorded in the two groups.

Study Design

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 200 participants
Allocation: Randomized
Intervention Model: Factorial Assignment
Masking: Single (Investigator)
Primary Purpose: Treatment
Official Title: Study on the Difference of Anastomotic Leakage Ratio Between Wide and Narrow Gastric Conduit During Minimally Invasive Esophagectomy
Study Start Date : September 2012
Estimated Primary Completion Date : December 2013
Estimated Study Completion Date : December 2014
Arms and Interventions

Arm Intervention/treatment
Experimental: Narrow Gastric Conduit
The group in which narrowed gastric conduit will be performed during minimally invasive esophagectomy
Procedure: Narrowed Gastric Conduit
The gastric conduit will be formed much narrower in the intervention arm during minimally invasive esophagectomy
Other Name: Narrowed Gastric Tube
Experimental: Wide Gastric Conduit
The group in which widened gastric conduit will be performed during minimally invasive esophagectomy
Procedure: Widened Gastric Conduit
A widened gastric tube will be formed during the surgery
Other Name: Wide Gastric Tube

Outcome Measures

Primary Outcome Measures :
  1. The anastomotic leakage rate [ Time Frame: the anastomotic leakage of participants will be followed for the duration of hospital stay, an expected average of 2 weeks ]
    The anastomotic leakage is a severe complication following minimally invasive esophagectomy. The definition of anastomotic leakage is determined as per the STS (SOCIETY OF THORACIC SURGEONS) database.
