Abstract:

Objective

To compare the effect of taTME and LapTME on postoperative LARS, and to explore whether transanal approach aggravates the occurrence of LARS.

Methods

The patients with rectal cancer from January 2018 to September 2019 were divided into taTME group and LapTME group according to the operation methods. Clinical parameters were collected, and anal function was evaluated by Wexner score and LARS score during perioperative period. All patients were followed up for twelve months. The parameters between the two groups were compared.

Results

Eighty cases were included, including forty cases in LapTME group and forty cases in taTME group. At three months after operation, there was no significant difference in Wexner score between the two groups (P>0.05). The taTME group had higher LARS score, but there was no significant difference (P>0.05). There was no significant difference in LARS and Wexner scores at six and twelve months after operation (P>0.05). The Wexner score and LARS score of the two groups were significantly improved with time.

Conclusions

taTME may have a greater impact on anal function in the early postoperative period, but no significant effect in anal function in the middle and long term. The transanal approach does not aggravate the occurrence of LARS.
