Laparoscopic resection for colorectal polyps: a single institution experience

Area of Science:

• Colorectal surgery
• Minimally invasive surgery
• Gastroenterology

Background:

• Endoscopic polypectomy is standard for colorectal polyps but has limitations.
• Laparoscopic resection is an alternative for large, difficult, or malignant polyps.
• This study assesses laparoscopic resection outcomes for challenging colorectal polyps.

Purpose of the Study:

• To evaluate the safety and efficacy of laparoscopic resection for colorectal polyps.
• To determine outcomes for polyps not amenable to endoscopic removal.
• To assess the role of laparoscopic surgery in managing malignant colorectal polyps.

Main Methods:

• A prospective database identified 78 patients undergoing laparoscopic resection for colorectal polyps (2005-2008).
• Inclusion criteria: malignant, large, difficult to snare, or incompletely excised polyps.
• Data collected included demographics, perioperative details, and histopathology.

Main Results:

• The study included 78 patients (median age 62.5 years); 79% underwent laparoscopic anterior resections.
• Median operating time was 125 minutes, with a 10.3% conversion rate to open surgery.
• No post-operative mortality; 8.9% experienced perioperative complications. Median hospital stay was 6 days.
• Median polyp size was 20 mm; 44.3% of polyps were malignant (including T1 and T2 tumors).
• Lymph node metastases were found in 8.6% of malignant cases.

Conclusions:

• Laparoscopic resection is a safe and effective treatment for colorectal polyps.
• It is particularly crucial for achieving adequate clearance of malignant polyps.
• This method provides a viable surgical option when endoscopic removal is not feasible.
