Abstract

Abstract:

Objective

To evaluate the application of laparoscopic-assisted partial intersphincteric resection(ISR)for ultralow rectal carcinoma.

Methods

From Jan. 2011 to Dec. 2014, laparoscopic-assisted pISR and laparoscopic-assisted tISR were performed respectively in 30 patients with ultralow rectal carcinoma.Oncologic safety and postoperative defecation functions were compared between the two groups.

Results

Postoperative defecation functions in the laparoscopic-assisted pISR group were significantly better than that in the laparoscopic-assisted tISR group(P> 0.05). There were no significant differences in oncologic safety between the two groups.After the median follow up of 24 months, there was no local recurrence and distant metastasis in the two groups[(20、24、26 patients) vs (17、20、21 patients), (10、6、4 patients) vs (13、10、9 patients), P< 0.05].

Conclusions

Laparoscopic-assisted pISR was a better way to keep the defecation functions for ultralow rectal carcinoma.
