The repair of an inguinal hernia is the surgical procedure most often performed. Complication rates after laparoscopic hernioplasty amount up to 19%, with hematoma/seroma, neuralgia, urinary retention, and chronic pain most frequently reported. Significant complications such as trocar site bleeding or bowel injury occur in 0.4-5.6%, and sporadic intraoperative lesions of the bladder have been mentioned. We present a 48-year-old patient with recurrent dysuria 3 years after transabdominal preperitoneal hernioplasty (TAPP). The preoperative diagnostic evaluation led to the assumption of an intravesical mesh dislocation. In spite of extensive adhesions between the mesh and the bladder wall, the mesh including five fixation coils could be removed via a suprapubic access. The postoperative period was without complications, and the patient has no complaints. The incidence of complications after laparoscopic hernioplasty is low. Still, severe problems such as mesh rejection, spermatic granuloma, or mesh migration into the small and large intestine do occur. Migration of a mesh into the urinary bladder has only been described twice.

Isologous isolated islets of Langerhans were transplanted into the peritoneum and, via the portal vein, into the liver of diabetic rats. In both groups almost normal blood glucose and serum insulin levels were achieved for a period of three months. Glucose tolerance tests were markedly improved. Morphological examination of the transplanted islets and immunohistochemical tests for insulin and glucagon showed the liver to be a more suitable site for islet grafting than the peritoneum.

We report here on our surgical experience with venous leakage of the cavernous bodies. Out of 159 patients operated on, 134 were availabe for long-term follow-up. Depending on the cavernosographic findings, one of three different surgical procedures was carried out: ligation of the deep dorsal vein of the penis, spongiosolysis, or ligation of the crura. 18% of the patients undergoing ligation of the deep dorsal vein, postoperatively attained spontaneous erections, while 35% needed adjuvant corpus cavernosum autoinjection therapy. Spongiosolysis gave a more favourable result: spontaneous erections in 30% and vasoactive drug-dependent erections in 35%. Crural ligation did not prove successful. No serious complications were encountered postoperatively. Our data suggest that venous surgery should only be offered to a selected group of patients comprising young impotent men with venous leakage, maybe in combination with arterial disease, and patients suffering from distal venous leakage. Old age, neurogenic disorders causing erectile dysfunction, and diabetes mellitus should represent exclusion criteria for venous surgery.
