Three-dimensional computed tomography in laparoscopic surgery for colorectal carcinoma

Area of Science:

• Surgical Oncology
• Medical Imaging
• Gastrointestinal Surgery

Background:

• Laparoscopic surgery for colorectal carcinoma offers advantages like smaller incisions.
• Preoperative imaging of major abdominal vessels is crucial for complex surgical procedures.

Purpose of the Study:

• To assess the utility of three-dimensional computed tomography (3DCT) in laparoscopic colorectal cancer surgery.
• To compare outcomes between laparoscopic and open surgery for colorectal carcinoma.

Main Methods:

• Seventy-two patients with colorectal cancer were divided into laparoscopic (n=16) and open surgery (n=56) groups.
• 3DCT was used to visualize major regional vessels including the superior mesenteric artery/vein and ileocecal artery.
• Outcomes, including anastomotic leakage and incision length, were compared between groups.

Main Results:

• Laparoscopic surgery resulted in significantly shorter incision lengths (4.625 cm) compared to open surgery.
• No anastomotic leakage occurred in the laparoscopic group, though no significant difference was found between groups.
• 3DCT provided preoperative visualization of key vessels like the inferior mesenteric artery and ileocecal artery.

Conclusions:

• 3DCT is a valuable tool for preoperative visualization in laparoscopic colorectal surgery.
• Enhanced visualization of regional vessels may contribute to secure anastomotic treatment.
• Laparoscopic surgery, aided by 3DCT, leads to shorter incisions and patient satisfaction.
