PURPOSE: This study aimed to investigate the efficacy and safety of transanal endoscopic microsurgery for radical resection of sigmoid cancer.
METHODS: 91 patients with sigmoid cancer who underwent sigmoid cancer resection were divided to the Control Group (43 patients who underwent conventional laparoscopic surgery and pathological specimens were taken through the abdomen) and the Study Group (48 patients who were subjected to transanal endoscopic microsurgery and pathological specimens were taken through the anus). Comparisons were made about the operation time and the amount of surgical bleeding of the two groups, as well as the postoperative exhaust time and postoperative visual analogue score (VAS) of the two groups. Also, factors like the complications, postoperative hospitalization time, additional analgesic treatment, and treatment efficacy of patients within the first month after the surgery were compared between the two groups. Finally, a 3-year follow up for patients was performed to record the 3-year recurrence rates.
RESULTS: The operation time and the amount of surgical bleeding of the Study Group were significantly lower than those of the Control Group (p<0.05); the 3-year recurrence rate of the Study Group was lower than that of the Control Group. On the contrary, the 3-year survival rate of the Study Group was significantly higher than that of the Control Group (p<0.05).
CONCLUSION: The application of transanal endoscopic microsurgery for radical resection of sigmoid cancer is worthy of clinical promotion despite its high technical requirements for the surgeon and certain degree of promotion difficulty, since it boasts high effective rate, low rate of complications, and the contribution for decreased recurrence rate and improved survival. Key words: anal endoscopic microsurgery, sigmoid cancer, effectiveness, safety analysis.
