What Researchers Did
Surgeons reviewed the outcomes of a two-stage surgical repair for children whose glans (the tip of the penis) separated after earlier hypospadias surgery.
What They Found
This retrospective chart review examined 49 children, aged 16 months to 18 years, who underwent a two-stage graft repair using oral mucosa or leftover foreskin tissue. Patients had undergone one to six prior operations, 11 had urinary fistulas, and 7 had penile curvature (chordee) needing repair during the first stage. After the first stage, 11 children showed skin flaps with reduced blood flow (described as dusky), and all 11 were treated with nitroglycerine ointment for 24 hours to improve blood supply; 6 of these 11 also received nine or ten 90-minute hyperbaric oxygen therapy sessions. Separately, 2 patients developed swelling (hypertrophy) of the mucosal grafts and 1 skin graft shrank, and these 3 required a second buccal mucosal graft to fix the problem. The abstract does not report how the graft or blood-flow outcomes compared between the children who received hyperbaric oxygen therapy and those who did not.
What This Means for Canadian Patients
This study is about pediatric reconstructive urology, not a hyperbaric oxygen therapy trial. Hyperbaric oxygen therapy appears only as one of several measures used alongside nitroglycerine ointment in a small subset of children with poor blood flow to a healing skin flap, and the abstract gives no outcome data isolating its effect. Families dealing with hypospadias complications should look to the surgical outcomes described here, not to any conclusion about hyperbaric oxygen therapy's effectiveness, since none is reported.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This is a retrospective, single-arm chart review with no control group and no reported comparison between the hyperbaric-treated and non-treated children, so no conclusions can be drawn about whether hyperbaric oxygen therapy affected healing.
