Systematic review of the implantation of penile prosthesis in major ambulatory surgery.

INTRODUCTION AND OBJECTIVE: Penile prosthesis (PP) implantation is an effective option for erectile dysfunction. Although initially PP surgery was carried out in an inpatient setting, there is a growing trend to implant PP as a major ambulatory surgery (MAS). This study aimed to perform a systematic review of the literature to identify available evidence of the implantation of PP under MAS setting and go carry out a comparison between MAS and inpatient procedures. MATERIAL AND METHODS: PubMed, EMBASE, Cochrane Library and MEDES electronic databases and non-indexed supplements for scientific congresses were searched to identify articles related to the surgical implantation of PP in MAS up to February 2021. Key search terms included penile prosthesis, erectile dysfunction, ambulatory surgery, ambulatory care, and surgery. RESULTS: Among 171 publications retrieved (51 PubMed, 73 EMBASE, 3 Cochrane, 2 using MEDES and 42 manual searching), 5 studies were finally selected. There were no significant differences between MAS or inpatient setting in terms of the type of device, surgical approach, or location of reservoir. Complication rates observed in both groups were similar. Implantation of PP in MAS was less expensive than inpatient surgery and was associated with acceptable patient satisfaction rates and adequate pain control. CONCLUSIONS: Studies demonstrated that outpatient PP surgery can achieve similar outcomes in terms of safety and satisfaction to implantation of PP in the inpatient setting, while it could reduce costs and improve the efficiency. This research could support decision makers to extend PP surgery into the ambulatory setting.

[Atypical bidirectional tachycardias]. / Taquicardias bidireccionales atípicas.

Two cases of bidirectional tachycardia are presented. The ventricular origin of these arrhythmias was assessed by His bundle recordings. Because of the V1 morphology of the ventricular complexes during tachycardia in one case and the unknown etiology in the other, these arrhythmias were considered to be atypical. The involved mechanisms and the causes inducing these tachycardias are discussed. Whatever the involved mechanism, our cases reaffirm the opinion that the terminology bidirectional tachycardia should be used only to describe an electrocardiographic pattern that may be caused by different electrophysiological mechanisms.
