Two cases of recurrent perianal suppuration are described in which the underlying pathology is believed to be pilonidal sinus disease affecting the perianal skin directly. This has given rise to intersphincteric fibrosis and, in one case, a subcutaneous track almost completely encircling the anus. The pathogenesis of the condition and its possible relationship to previous surgery are discussed.
One hundred and two patients with a pilonidal sinus treated by minor excision had a life-table of 5-year freedom from recurrence of 89% provided that they attended a dressing clinic until the wound healed. With failure to attend the clinic, the recurrence freedom fell to 57% (P less than 0.004). Age, sex, acute abscess, previous excision, presence of hairs and the number of midline pits and lateral abscesses did not significantly influence the result. The method supersedes more extensive procedures, but should be tested against even less traumatic techniques.

This article describes the care of a young man following surgery for a pilonidal sinus and the follow-up care after removal of the sutures from the wound. Unfortunately, the wound became infected and dehisced on removal of the sutures, causing the patient to have problems with both wound healing and body image.
The acquired theory of puncture of hairs on the side of natal cleft is popular. There is still controversy on "pilonidal sinus" surgical treatment. A modification in the natal cleft cicatrization should be the correct surgical therapy. Postoperative treatment as hairs removal, infection control, wound healing are mandatory.
The authors report their experience in the surgical management of pilonidal sinus. During a 3-year period (1989-1991) 106 patients underwent primary closure. Average postoperative stay was 5.5 days, while mean healing time was 14.6 days. During the follow up, 3 patients developed a true recurrence (3.26%). After a critical review of the literature, the authors emphasize the importance of primary closure in the surgical treatment of pilonidal disease.
The Authors report their own experience concerning the treatment of the sacrococcigeal pilonidal sinus disease. Results obtained with the "open" and "closed" techniques were compared. Although results were similar in terms of complications and relapses, the closed technique is to be preferred, because it allows a more rapid return to working activities. In the light of the new trends of sanitary economy a modulated treatment of the disease is suggested.
In a personal series, forty-five patients with postanal pilonidal sinus have been treated by the Karydakis operation. The sinus is excised using an eccentric elliptical incision, the medial edge of which is undermined and advanced across the midline to produce a lateral vertical scar and shallower natal cleft. Forty patients were followed up for an average of thirty-three months. There were two wound haematomata, four wound infections and two recurrences, one of which was not in the scar. A low recurrence rate can be achieved by flattening the natal cleft and closing the skin away from the midline.

The authors report on their preliminary experience with ultrasound as a screening examination in neonates presenting pilonidal sinuses. Of the 100 patients examined over the 2 previous years, three pathological cases were found (1 tethered cord, 1 lipoma of the filum terminale and one localized hydromelia). Abnormal or doubtful cases were confirmed or further investigated by magnetic resonance. Ultrasound seems to be an accurate technique for the detection of malformation of spinal canal content in neonates under one month of age.
During a period of 18 months, from January 1988 to June 1989, 70 patients were treated for pilonidal sinus disease in a Multi-Specialty Military Clinic. There were 62 men and 8 women, with a median age of 19 years (range 18 to 35). All were managed as outpatients under local anesthesia. When an abscess was involved, the surgical procedure included incision, drainage, curettage, peroxide irrigation, and CO2 laser therapy. For the other processes, the surgical procedure included excision of sinus tissue and lateral fistulas, curettage, peroxide irrigation, and CO2 laser therapy with secondary healing. Morbidity was minimal. Healing time ranged from 14 days to 8 weeks, yet most sinuses healed in 4 weeks. The complications observed--pain, bleeding, and skin bridging--were minor. All recurrences but three were minor and healed completely after additional local treatment (4.3 percent major recurrences). Preliminary satisfactory results are reported, supporting a more conservative approach in the treatment of this often overtreated disease.
Most failure and recurrences after excision and grafting occur during the first five months postoperatively. We concluded that this most likely indicated inadequate excision rather than inefficacy of the procedure. For small pilonidal sinus with minor sinus tract and shallow natal cleft, excision with primary closure would seem to be the best procedure. However, for extensive or recurrent sacrococcygeal pilonidal disease, wide excision with primary split thickness skin grafting is superior. We reviewed 58 patients who had undergone excision of extensive or recurrent pilonidal disease, with primary skin grafting. More than 72 per cent of these patients had recurrent disease when first seen at the Cleveland Clinic. The average hospital stay was 9.8 days; the total disability period, time off work, was 28 days; recurrence rate, 1.7 per cent, and failure rate, 3.4 per cent. This procedure is recommended for recurrent or extensive pilonidal disease.

A silicone foam sponge has been used to replace the daily packing of deep granulating wounds with moist sterile gauze. In the treatment of pilonidal sinus use of the sponge demands less nursing time and is more comfortable for the patient than the excision and open granulation technique. Patients can usually return to work soon after operation. The method has many applications in surgery, and widespread application of the technique to the management of granulating wounds could result in considerable savings to the NHS in money and skilled nursing time.
