(546) Outcomes of Two Novel Techniques for Low Submuscular Reservoir Placement: Thalia Stich and Transfacial Fixation

Abstract

Abstract Introduction Penile Implant reservoir complications continue to drive surgical technique innovation to avoid catastrophic complication typically affiliated with theoretical placement in the space of Retzius. The high submuscular technique (versus initially described low submuscular) aimed to reduce migration/herniation. Most high submuscular technique complications are cosmetic, however, unintentional bowel injury and difficulty with extraction of these reservoirs has been reported. Furthermore, reservoirs left via drain and retain technique have been reported to cause significant bowel complications most typically when the reservoir or pressure regulating balloon unknowingly resides intraperitoneally. Objective We report outcomes of two surgeons who independently invented and published novel techniques allowing for low submuscular reservoir placement (and thus avoid blind puncture above the arcuate line) to help avoid reservoir complications. Methods Two surgeons’ technique outcomes were assessed. The first surgical technique (T1) involves suturing an additional implant connector collar to the pubic bone with a permanent stitch. This collar acts as a backstop to prevent reservoir herniation or migration into the scrotum. It can also be used to prevent upward migration of drain and retain reservoirs as the retained reservoir is capped. The second surgical technique (T2) involves placing a right angle outside in of the fascia after a pocket is cleared below the muscle and pulling the implant tubing through this defect. This approach stops the prb or reservoir at the puncture site. Results T1 was performed 55 times for reservoir fixation and 7 times for drain and retain fixation. Mean follow up is 11 months. One infection occurred necessitating reservoir removal (and cutting of permanent stitch) which was easily accomplished. No other complications or patient complaints from this technique have occurred. Average case time increase is 5-10 minutes. T2 has been performed 31 times for reservoir fixation with no complications or patient complaints. Average case time increase is < 5 minutes. Conclusions Although submuscular reservoir techniques decrease catastrophic complications and are widely adopted, they are not without risk. We report success of two independent techniques that demonstrate safety and feasibility with low reservoir placement.
