Hand-assisted laparoscopic colorectal surgery for colorectal polyps: single institution experience / ; Ranka asistuojamoji laparoskopinė chirurgija gydant endoskopiškai nepašalinamus storosios žarnos polipus.

Objective. To assess outcomes of a hand-assisted laparoscopic approach (HALS) for the management of difficult colorectal polyps. Methods. In 2007–2013 at the Institute of Oncology, Vilnius University, 25 HALS colorectal procedures for polyps which could not be treated by endoscopy were performed. Demographic data, histology of the biopsy, type of surgery, length of postoperative stay, complications and final pathology were reviewed prospectively. Results. 25 patients with a mean age of 65.88±13.3 years underwent HALS polypectomy. Preoperative morphology was: 20 (80%) patients with adenomas and 5 (20%) – Ca in situ. Laparoscopic mobilization of colonic segment, and colotomy with removal of polyp was performed for 5 (20%) polyps. Laparoscopic segmental bowel resection was performed in 20 (80%): anterior rectal resection with partial total mesorectal excision – 10 (40%), left hemicolectomy – 6 (24%), sigmoid resection – 3 (12%) and resection of transverse colon in 1 (4%). Mean postoperative hospital stay was 6.4±2.5 days. Two patients (8%) had complications – urinary tract infection. Both recovered after conservative treatment. Mean polyp size was 3.8±2.2 cm. Final pathology revealed polyp (n = 1), tubular adenoma (n = 3), tubulovillous adenoma (n = 12), Carcinoma in situ (n = 7) and invasive cancer (n = 2). Both patients underwent laparoscopic left hemicolectomies (HALS) in 14 and 10 days after laparoscopic colotomy and polypectomy. Conclusions. For the management of endoscopically unresectable polyps, laparoscopic polypectomy is currently the technique of choice.
