Significance of the localization of small tumors at laparoscopic large bowel resections

Introduction: The premalignant and malignant diseases of the colon could be identified earlier owing to the colonoscopic screening. Although large part of these small lesions could be removed by the new intraluminal techniques (endoscopic submucosal dissection), the other tumors needs minimal invasive surgical (laparoscopic large bowel resection) procedure. To find these small, T1-T2 tumors during the operation is usually very difficult, or impossible owing to the nature of the laparoscopic technique. The correct anatomical localization with the preoperative colonoscopy is false in about 15–20% of the cases, and…
