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 Intervention Phase
Rectal Cancer
Procedure: Single Incision Laparoscopic Surgery
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Prospective Randomized Study of Single Incision Laparoscopic Surgery Versus Conventional Laparoscopic Surgery for Rectal Cancer

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

Secondary Outcome Measures:
  • 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

  • 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.

  • 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.
