Gomco circumcision in the office in patients heavier than 5.5 Kg and/or older than 3 months

Although most pediatric urologists do not perform clamp circumcisions in boys older than 3 months or heavier than 5.5 kg, there are no universally accepted guidelines on the optimal patient age or weight.

To compare outcomes of office circumcision within and outside these traditional patient parameters.

This is a retrospective review of circumcisions performed by a single surgeon from 2019 to 2022. Demographics reviewed include age and weight at time of circumcision, gestational weeks at birth, as well as post-procedure: bleeding, planned and unplanned visits, adhesions/concealment, and interventions related to the circumcision. "Active Bleeding" was defined as bleeding occurring after discharge requiring intervention with pressure, sutures, or cautery. "All Bleeding" included Active Bleeding, and cases where bleeding was controlled at home with pressure, stopped by the time of arrival at clinic or emergency department, and immediate bleeding after circumcision controlled before discharge.

During the study period, 773 Gomco circumcisions were performed. A total of 603 patients (78%) had post-procedure evaluation 2 weeks after circumcision. 574 patients (74%) were less than 5.5 kg and 199 (26%) over. Only age corrected for gestation was used in the study: 658 (85%) were younger than 3 months and 115 (15%) older. There was no significant difference in Active Bleeding based on weight (p = 0.3819) or age (p = 0.2798), and no difference in All Bleeding based on weight (p = 0.2072). There was a significant difference (p = 0.0258) in All Bleeding based on age. There was also a significant difference in unexpected visits based on weight (p = 0.0258) and age (p = 0.0131). With regards to adhesions, there was no statistical significant differences when comparing weight or age. However, older and heavier boys had significantly more concealment (5% vs <1%).

Our study showed Active Bleeding rates 0.5-0.9% higher in the older and heavier group, although the difference did not reach statistical significance. We found a significantly increased rate of unexpected post-procedure visits of around 3.5-4.7% in those patients older than 3 months and heavier than 5.5 kg. Also, post -procedure concealment was significantly increased in the older and heavier boys. Modifications of the dressing for high risk groups could reduce the risk of bleeding, and efforts on pre-circumcision education of the families might ameliorate unexpected visits. Exlcuding patients with hidden penis or performing penoscrotal skin tacking at the time of the gomco circumcision could decrease concealment rates in the higher risk patients.

Gomco clamp circumcision is safe in patients over 5.5 kg and older than 3 months, with a less than 1% higher risk of bleeding, which in the current study was controlled without the need for general anesthesia or transfusions. Broadening the inclusion criteria for office clamp circumcisions could reduce costs and make the procedure available to patients who cannot afford to have the surgery under general anesthesia.
