Brief Summary:
  • To compare surgical and oncological outcomes in patients underwent to colorectal resection with 3D vs 2D laparoscopic technique.
  • To evaluate the visual overload in surgeons using 3D laparoscopic technique.

Condition or disease
Colorectal Cancer Inflammatory Bowel Disease

Detailed Description:

3 Dimensional (3D) Camera system is a new technique introduced into laparoscopic surgery field, adding the depth perception. Even if in the first 2000' the old 3D camera had negative results in terms of quality of images, thanks to technological progress the new 3D systems have reached high quality.

This new technology has been widely tested in pelvic trainer, not yet in live surgery. Moreover effects on surgeons visual work load are unknown.

Aim of the present study is to evaluate the potential superiority of 3D laparoscopic technique on 2D one in terms on postoperative complications and oncological radicality (in case of neoplastic disease).

Secondary aim is to study the possible major visual stress on surgeons brain caused by 3D camera rather than 2D videos.

ENROLLMENT All patients affected by neoplastic or inflammatory colorectal disease are enrolled in the study.

Preoperative, intraoperative e postoperative data are collected dividing all the patients according the camera system used during the operation: 2D group vs 3D group.

Preoperative data: sex, age, date of birth, id, date of admission, past medical history Intraoperative data: date of surgery, pathology, site of pathology, type of surgery and duration, intraoperative blood loss, other intraoperative problems, loop ileostomy, colostomy, drain positioning, intensive care unit admission Postoperative data (at 30th postoperative day): complications according to Dindo-Clavien scale (Dindo-Clavien classification of surgical complications), type of complications, transfusion, reoperation, other treatments, histology specimen report.

At the end of every operation, the 1st surgeon has to fill in the NASA (The National Aeronautics and Space Administration) task load index and the Simulator Sickness questionnaire.

Number of participants: 350 Years necessary: 2

Study Type : Observational
Estimated Enrollment : 350 participants
Observational Model: Other
Time Perspective: Prospective
Official Title: 3D vs 2D Colorectal Resections and Valuation of Visual Load of Surgeons
Study Start Date : January 2016
Estimated Primary Completion Date : October 2017
Estimated Study Completion Date : October 2017

Primary Outcome Measures :
  1. Postoperative complications [ Time Frame: through study completion, an average of 2 years ]
    The postoperative course is evaluate in all patients undergone to colorectal laparoscopic surgery and classified according to the Dindo-Clavien scale at 30 days after surgery (Dindo-Clavien classification of surgical classification).

Secondary Outcome Measures :
  1. Oncological radicality [ Time Frame: through study completion, an average of 2 years ]
    The R0/R1 rate is evaluate in patients undergone to 3 dimensional or 2 dimensional laparoscopic colorectal surgery.
