Comparison of Laparoscopic and Open Total Mesocolic Excision With Central Vascular Ligation for Right Colon Carcinoma

The goal of this observational comparative study is to assess whether laparoscopic complete mesocolic excision with central vascular ligation (L-CME with CVL) provides improved short-term surgical outcomes compared with open complete mesocolic excision with central vascular ligation (O-CME with CVL) in patients with right-sided colon cancer.

The primary questions this study aims to answer are:

Does laparoscopic CME with CVL reduce blood loss, postoperative complications, and length of hospital stay compared with open CME?

Does laparoscopic CME with CVL achieve equivalent surgical specimen quality and short-term oncological outcomes compared to the open approach?

Researchers compared laparoscopic versus open right hemicolectomy with CME and CVL in adult patients diagnosed with right colon cancer who were eligible for elective surgical resection.

Participants underwent standard preoperative assessment, including clinical evaluation, laboratory testing, imaging studies, colonoscopy, and biopsy confirmation. Surgical treatment consisted of either laparoscopic or open complete mesocolic excision with central vascular ligation, performed according to standardized oncologic surgical principles. Postoperative care followed an enhanced recovery protocol.

Primary outcome measures included operative time, intraoperative blood loss, time to first flatus, postoperative complications, and duration of hospital stay. Secondary outcomes included quality of the surgical specimen (lymph node yield, mesocolic integrity, and margin status) and short-term oncologic outcomes, including early recurrence during follow-up.
