[Single- versus double-suture knot for positioning the cutting plane in circumcision with a stapler].

OBJECTIVE

To observe the clinical effect of single-suture versus that of double-suture knot in positioning the cutting plane in circumcision with a stapler.

METHODS

We randomly assigned 120 patients with redundant prepuce or phimosis into three groups of an equal number to receive traditional circumcision without suture knot (group 1), circumcision with single-suture knot (group 2), and circumcision with double-suture knot (group 3) for positioning of the cutting plane. We recorded and compared the operation time, intraoperative blood loss, the rates of frenulum sewing, non-frenulum sewing, poor frenulum sewing and surgical conversion, intraoperative anxiety of the doctors, postoperative ecchymosis, and satisfaction with the retained ventral and dorsal prepuce and postoperative penile appearance among the three groups.

RESULTS

There were statistically significant differences among the three groups in the surgery time, intraoperative blood loss, the rates of frenulum sewing, non-frenulum sewing, poor frenulum sewing and surgical conversion, intraoperative anxiety of the doctors, and satisfaction with the retained ventral and dorsal prepuce and postoperative penile appearance, (P < 0.05), but not in postoperative ecchymosis (P = 0.849). The rate of satisfaction with the retained dorsal prepuce was remarkably higher in group 3 than in group 2 (P = 0.003), and the intraoperative anxiety rate of the doctors was lower in the former than in the latter group (P = 0.003).

CONCLUSIONS

Both single- and double-suture knots for positioning the cutting plane in circumcision with a stapler can help reduce the operation time, intraoperative blood loss, the rates of frenulum sewing, non-frenulum sewing, poor frenulum sewing and surgical conversion, intraoperative anxiety of the doctors, and satisfaction with the retained ventral and dorsal prepuce and postoperative penile appearance, and double-suture knot positioning has an even higher application value in decreasing the intraoperative anxiety of the doctors and increasing the satisfaction with the retained dorsal prepuce.
