Gas (Oxygen) insufflation: A new technique for the visualization of the operative field during hypospadias surgery.

OBJECTIVE

Maintaining a bloodless operative field is a crucial step in achieving success and reducing complications in hypospadias surgery. So, far, the most harmless and least damaging technique in terms of penile tissue oxygenation during hemostasis has not still been defined. We aimed to present our new technique of gas (oxygen) insufflation for better visualization of the operative field, and to compare this with the control group, where a wet sponge was used for hemostasis.

MATERIAL AND

METHODS

A total of 28 patients with primary distal hypospadias who were treated with modified tubularized incised plate urethroplasty (TIPU) repair between March 2017 and October 2018 were evaluated prospectively. The patients were divided randomly into two groups. While only a wet sponge was used to clean hemorrhagic area in the control group (group I) (n=12), gas (oxygen) insufflation was used to visualize the operative field during the operation in the patient group (group II) (n=16). The patients' ages, operation time, follow-up durations, and postoperative complications were documented and statistically compared.

RESULTS

The mean ages and follow-up durations of both groups were found to be similar. The operation time was statistically shorter in group II than in group I (p=0.01). Eight patients (66.7%) in group I showed a complication, while 2 patients (12.5%) in group II showed a complication (p=0.005).

CONCLUSION

The gas (oxygen) insufflation technique provides good visualization during the dissection step of hypospadias surgery and results in better postoperative outcomes. Therefore, we think that this technique can be preferred as an alternative method for the visualization of the operative field in hypospadias surgery.
