Background: Sacrococcygeal pilonidal sinus is a common condition usually affecting young-to-middle-aged men. For managing sacrococcygeal pilonidal illness, a variety of lateralizing surgical flap procedures based on this principle have been published, including the Karydakis flap, Limberg flap, modified Limberg flap, Z-plasty, and Y-V advancement flap.

Aim: To compare the outcome of simple excision with primary closure versus rhomboid excision with limberg flap for sacrococcygeal pilonidal sinus.

Methodology: Randomized control study conducted in Surgery Department, Ghurki Trust Hospital, Lahore. 90 patients fulfilling the inclusion criteria were selected from wards and were randomly divided in two equal groups. In group A, patients underwent rhomboid excision with limberg flap. In group B, patients underwent simple excision with primary closure. The operation was performed under spinal anesthesia. After surgery, patients were evaluated every 24 hours if they are able to move on their own then they were discharged and hospital stay was noted. Then after 10 days, patients will be called in OPD for assessment of wound healing. If wound did heal and patient complained of pain (VAS>4) and cannot sit and have fever (temp>100^oF)

Results: The average age in group A was 44.37±15.42 years while that in group B was 45.24±14.50 years. In group A there were 23(51.1%) males and 22 (48.9%) females whereas in group B there were 25(55.6%) males and 20(44.4%) females. There was difference significant in the mean stay in hospital in both groups (p-value=0.002).

Conclusion: The conclusion of the study, that primary sacrococcygeal pilonidal sinus disease and rhomboid excision with Limberg's flap is an effective treatment.
