RESUMO
The objective of this study was to anatomically describe the relationship of penile intracavernosal pillars to penile surgery, specifically corporal dilation during penile prosthesis placement. Corpora cavernosa from four embalmed male cadavers were dissected and subjected to probe dilation. Corpora were cross-sectioned and examined for the gross presence and location of pillars and dilated spaces. Infrapubic penile prosthesis insertion was performed on one fresh-frozen cadaveric male pelvis, followed by cross-sectioning. A single patient had intracavernosal pillars examined intraoperatively during Peyronie's plaque excision and penile prosthesis insertion. Intracavernosal pillars were identified in all cadavers and one surgical patient, passing obliquely from the dorsolateral tunica albuginea across the sinusoidal space to the ventral intercorporal septum. This delineated each corpus into two potential compartments for dilation: dorsomedial and ventrolateral. Dorsal dilation seated instruments and prosthetics satisfactorily in the dorsal mid glans and provided additional tissue coverage over weak ventral areas of the tunica albuginea, while ventrolateral dilation appeared to result in ventral seating and susceptibility to perforation. Intracavernosal pillars are an important anatomic consideration during penile prosthesis placement. Dorsal dilation appears to result in improved distal seating of cylinder tips, which may be protective against tip malposition, perforation or subsequent erosion.

Amyand's hernia is a rare presentation of an appendix within an inguinal hernia sac. It is commonly mistaken for an incarcerated or strangulated hernia. Prompt diagnosis requires awareness of this entity, as well as associated radiologic findings on computed tomography (CT) and ultrasound. Treatment includes antibiotics and surgical intervention involving appendectomy and hernia repair. We present a case of a premature infant who developed systemic symptoms after a circumcision and was eventually diagnosed with an Amyand's hernia with concurrent appendicitis.
