Use of a prefabricated tunica vaginalis fascia flap to reconstruct the tunica albuginea after recurrent penile prosthesis extrusion.

PURPOSE: Although a penile prosthesis usually perforates into the urethra, it can extrude through the glans or corporeal shaft. Various materials have been used to reconstruct tunica albuginea but no method of repair has been satisfactory in such difficult cases. Repair of the weakened tunica albuginea should ideally be performed with autogenous tissues. Inasmuch as the scarred tissue bed is inadequate to ensure graft survival and no local flaps are available for this purpose, prefabrication of a local flap has been designed. MATERIALS AND METHODS: We present 2 cases in which the distal corpus was reconstructed with a prefabricated tunica vaginalis fascia flap. The first stage involves grafting rectus fascia onto the external tunica vaginalis of the testicle. At the second stage the prefabricated tunica vaginalis fascia flap is transposed to the distal corpus, placing it as a buttress between the cylinder and urethra medially or between the cylinder and thin lateral and distal tunica albuginea. The flap also replaces part of the tunica albuginea. RESULTS: In both patients repair of the tunica albuginea was successful and each has a functioning inflatable penile prosthesis at 2 1/2 1 1/2 years postoperatively, respectively. CONCLUSIONS: Reconstruction of the weak tunica albuginea with a prefabricated tunica vaginalis fascia flap is an excellent procedure in these difficult cases.

Entrapment neuropathy in laparoscopic herniorrhaphy.

In laparoscopic hernia repairs, the staples used to affix prosthetic mesh have resulted in entrapment neuropathies. This paper describes the diagnosis and treatment of nine cases of entrapment neuropathy. Injuries to all the branches of the lumbar plexus, with the exception of the obdurator nerve, have been treated. Generally, the entrapments are self-limiting, but chronic disability requiring surgical intervention can occur. Staple removal and neurolysis controlled the severe, chronic pain of one femoral nerve entrapment. A thorough understanding of the anatomy of these nerves can prevent stapling in the areas of danger and thus greatly reduce the incidence of this complication.

Laparoscopic herniorrhaphy.

Laparoscopic preperitoneal prosthetic repair of inguinal and femoral hernias was done in 27 patients, including 18 indirect, nine direct, and two femoral hernias. In four patients bilateral hernias were repaired simultaneously. General anesthesia with endotracheal intubation was used in all patients. Three laparoscopic cannulas were inserted. The peritoneum overlying the internal inguinal ring and floor of Hesselbach's triangle was opened. If an indirect hernia sac was found, it was dissected off the cord structures. A polypropylene prosthesis was used to occlude any potential canal space and to reinforce the pelvic floor. No major operative complications or early recurrences (follow-up, 1-7 months) occurred. Patients were to return to full employment an average of 5 days after surgery (range, 3-7 days).

Pathologic rupture of the spleen due to Salmonella dublin infection.

A case of Salmonella dublin infection presenting as pathologic rupture of the spleen is reported. Because the incidence of salmonellosis is increasing, the importance of operative and tissue cultures in cases with subcapsular splenic hemorrhage and splenic rupture is stressed. Cephalosporins will be ineffective in salmonellosis, which should be treated with chloramphenicol, ampicillin, or sulfamethoxizole-trimethoprim.
