Abstract:
Objective To evaluate the clinical efficacy of laparoscopy combined with colonoscopy for small colorectal space occupying lesions (equal or less than 3 cm). Methods From January 2010 to January 2015,a total of 41 cases of small colorectal space occupying lesions (equal or less than 3 cm)were treated under general anesthesia with laparoscopic surgery combined with colonoscopy.The patients were placed at the lithotomy position.After the establishment of pneumoperitoneum,injection of methylene blue for staining was carried out under colonoscopy. Laparoscopic titanium clipping positioning was conducted, and then the colonoscope was withdrawn.According to the intraoperative frozen pathological results,bowel resection surgery or colorectal surgical resection was selected. Results All the 41 cases of laparoscopic combined with colonoscopic surgery were successfully completed, with no conversion to laparotomy.There were 9 cases of preoperative diagnosis of precancerous lesions,6 of which were found neoplasia in the colon epithelium with intraoperative pathological diagnosis,with 3 cases of Tis adenocarcinoma.Among 32 cases of preoperative diagnosis of stage 0 -Ⅰ colorectal cancer,there were 29 cases of intraoperative and postoperative diagnosis of stage Ⅰ (23 cases of T1 N 0 M0 adenocarcinoma and 6 cases of T2 N 0 M0 adenocarcinoma)and 3 cases of stage Ⅲ (T2 N 1 M0 adenocarcinoma).Two cases were multiple lesions.Bowel resection was performed in colon intraepithelial neoplasia and Tis lesions of colorectal cancer,while resection of colorectal cancer was conducted in stage T1 -T2 colorectal cancer.Two patients with colonic epithelial neoplasia were followed up for 9 and 12 months,without recurrence.The remaining 39 cases were followed up for 24 -49 months,with a median of 38.6 months. Among the 35 cases of colorectal cancer,colonoscopy detected local recurrence in 1 case of T2 N 1 M0 adenocarcinoma (stage Ⅲ)after 34 postoperative months.No metastasis was found in all the patients. Conclusion Laparoscopy combined with colonoscopy for small diameter (equal or less than 3 cm)benign tumor or stage Tis -T2 malignant colorectal cancer has advantages of both endoscopy,especially suitable for difficultly located or removed lesions,which can improve the positioning precision and surgical safety.
