Laparoscopic total colectomy using left-to-right dissection: comparison with the conventional open approach

Area of Science:

• Surgical Oncology
• Minimally Invasive Surgery
• Gastrointestinal Surgery

Background:

• Familial adenomatous polyposis and synchronous colorectal cancer necessitate surgical intervention.
• Total colectomy is a procedure to remove the entire colon.
• Minimally invasive surgical techniques are increasingly adopted in gastrointestinal procedures.

Purpose of the Study:

• To compare the outcomes of laparoscopic total colectomy with left-to-right dissection against the traditional open surgical approach.
• To evaluate key surgical and postoperative parameters between the two techniques.

Main Methods:

• A retrospective matched-cohort study comparing 20 patients undergoing laparoscopic total colectomy (left-to-right dissection) with 28 patients undergoing open total colectomy.
• Patients in both groups had familial adenomatous polyposis or synchronous colorectal cancer.

Main Results:

• Laparoscopic colectomy demonstrated significantly lower estimated blood loss (P=0.008).
• While operative time was longer in the laparoscopic group (P<0.001), patients experienced faster return of bowel function (2 days sooner, P<0.001) and earlier tolerance of a soft diet (1 day sooner, P=0.005).
• No conversions from laparoscopic to open surgery were required, and postoperative complication rates were similar between groups.

Conclusions:

• Laparoscopic total colectomy utilizing the left-to-right dissection technique is a safe and effective alternative to open surgery.
• This approach is particularly suitable for surgeons proficient in laparoscopic procedures.
• The technique facilitates reduced blood loss and accelerated patient recovery.
