Treatment of pilonidal sinus by primary closure with a transposed rhomboid flap compared with deep suturing: a prospective randomised clinical trial.
OBJECTIVE
To assess two techniques of primary closure after excision of pilonidal sinus.


METHODS
Prospective randomised study.


METHODS
University department of surgery, United Arab Emirates.


METHODS
46 patients with chronic pilonidal sinus disease, 24 treated by rhomboid flap transposition, and 22 by deep suturing technique.


RESULTS
Early mobility and recurrence.


RESULTS
All patients in the rhomboid flap transposition group healed their wounds primarily compared with 17 in the primary deep suturing group (77%). (P = 0.02). Five patients wounds broke down as a result of haematoma and infection (23%). The mean hospital stay for the rhomboid flap technique was 6 days compared with 9 days after deep suturing, and the mean follow up for both groups was 18 months, the rhomboid flap group returned to work a mean of nine days earlier than the deep suturing group (23 days). No recurrence has been identified yet in the rhomboid flap group, while 2 recurrences have developed in the deep suturing group (9%).


CONCLUSIONS
Primary closure after excision of pilonidal sinus with a transposed rhomboid flap is successful in the management of pilonidal sinus and is superior to primary closure by deep suturing.
