Minimally invasive left colectomy with total intracorporeal anastomosis versus extracorporeal anastomosis. A single center cohort study. Stage 2b IDEAL framework for evaluating surgical innovation.

Purpose: Performing intracorporeal anastomoses in minimally invasive colon surgery appears to provide better short-term outcomes for patients with colon cancer. The aim of the study is to compare surgical aspects and short-term outcomes between intracorporeal and extracorporeal techniques in left colectomies with both laparoscopic and robotic approaches and evaluate advantages and disadvantages of intracorporeal anastomosis according to IDEAL framework (Exploration, stage 2b).

Methods: This is a single center, ambispective cohort study comparing total intracorporeal anastomosis (TIA) and standard surgery with extracorporeal anastomosis (EA).

Laparoscopic and robotic intracorporeal resection and end-to-end anastomosis in left colectomy: a prospective cohort study - stage 2a IDEAL framework for evaluating surgical innovation.

Purpose: To analyze the safety and feasibility of intracorporeal resection and anastomosis in upper rectum, sigmoid, and left colon surgery, via both laparoscopic and robotic approaches. The secondary aim was to assess possible short-term differences between laparoscopic versus robotic surgery.

Methods: A prospective observational cohort study according to IDEAL framework exploration and assessment stage (Development, stage 2a), evaluating and comparing the laparoscopic approach and the robotic approach in left colon, sigmoid, and upper rectum surgery with intracorporeal resection and end-to-end anastomosis.

Experimental study of the quantification of indocyanine green fluorescence in ischemic and non-ischemic anastomoses, using the SERGREEN software program.

Tissue ischemia is a key risk factor in anastomotic leak (AL). Indocyanine green (ICG) is widely used in colorectal surgery to define the segments with the best vascularization. In an experimental model, we present a new system for quantifying ICG fluorescence intensity, the SERGREEN software.

When should indocyanine green be assessed in colorectal surgery, and at what distance from the tissue? Quantitative measurement using the SERGREEN program.

Background: Suture dehiscence is one of the most feared postoperative complications. Correct intestinal vascularization is essential for its prevention. Indocyanine green (ICG) is one of the methods used to assess vascularization, but this assessment is usually subjective.
