Prospective Randomized Study of SILS Versus CLS for Rectal Cancer

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01579721
Recruitment Status : Completed

Brief Summary:

Background: Single-port laparoscopic surgery is emerging as a method to improve morbidity and cosmetic benefits of conventional laparoscopic surgery and minimize the surgical trauma. However, the feasibility of this procedure in rectal surgery has not been determined yet. The aim of this study is to evaluate our initial experience using single port access in laparoscopic rectal surgery.

Design: randomized, prospective clinical study Patients: 40 patients

Condition or disease Intervention/treatment Phase
Rectal Cancer Adenocarcinoma Procedure: Single Incision Laparoscopic Surgery Phase 4

Arm Intervention/treatment
Experimental: SILS-group

Primary Outcome Measures :
  1. morbidity [ Time Frame: 30 days ]
    The purpose of this study is to compare 30-days postoperative morbidity between the two groups

Secondary Outcome Measures :
  1. immunology [ Time Frame: 72 hours postoperatively ]
    to compare results of blood-samples (C-reactive protein, leucocyte-count and interleukin-6) 72 hours postoperatively between the two groups

  2. postoperative outcome [ Time Frame: 5 days postoperatively ]
    to compare postoperative results (postoperative pain, time to bowel function, time to regain full diet and mobilisation) between the two groups.

  3. oncology [ Time Frame: 30 days ]
    Comparison of the oncological results (quality of specimen, completeness of mesorectal fascia, circumferential resection margin, number of harvested lymphnodes, TNM-classification) between the two groups.
