Original technique for small colorectal tumor localization during laparoscopic surgery

Area of Science:

• Surgical Oncology
• Gastroenterology
• Medical Imaging

Background:

• Accurate localization of small colonic tumors is crucial for effective laparoscopic resection.
• Existing localization techniques can be inconclusive and associated with morbidity.
• A novel method using preoperative endoscopic clipping and intraoperative ultrasound is presented.

Purpose of the Study:

• To evaluate the efficacy and safety of a two-step technique for small colonic tumor localization.
• To assess the utility of preoperative endoscopic clip application and intraoperative ultrasound in laparoscopic colorectal surgery.

Main Methods:

• Eight patients with small colonic lesions underwent preoperative endoscopic application of two metal clips around the lesion.
• During laparoscopic surgery, intraoperative ultrasound was used to locate the clips.
• Laparoscopic colectomy was performed following clip localization.

Main Results:

• Endoscopic clip application was successful and complication-free in all patients.
• No clip dislodgement occurred.
• Intraoperative ultrasound successfully visualized the clips in all cases within 5-17 minutes, with no associated morbidity.
• Resected specimens consistently contained the target lesions with surrounding clips.

Conclusions:

• Endoscopic metal clipping and intraoperative laparoscopic ultrasound provide an easy, safe, and accurate method for locating small colonic tumors.
• This technique enhances the precision of laparoscopic colorectal resections.
