Dislocation of the epicardial pacemaker into the peritoneal cavity is an uncommon but potentially life-threatening complication. We report a case of a 74 year old with an abdominally implanted epicardial pacemaker that migrated through the peritoneum to the excavatio rectovesicalis. The laparoscopic approach was chosen because of the increased risks of perioperative morbidity and decreased survival. The generator was implanted into a pocket beneath the anterior rectus sheath and the lead was peritonalized with a running suture. In conclusion, a laparoscopic retrieval is feasible and safe in the treatment of a displaced pacemaker in the rectovesical pouch.

Symptomatic benign conditions of seminal vesicle (lesions like cysts which need intervention) can be managed laparoscopically because the vision is better and the access is easier than in open surgery [1, 2].

Symptomatic Mullerian duct cyst is a rare entity in children. A 9-month-old male infant presented with bowel and urinary obstructive symptoms. Imaging investigations revealed a cystic mass in the rectovesical pouch compressing bladder neck and rectum. At laparotomy, a Mullerian duct cyst was found. Most of the cyst was excised and the remaining cyst mucosa was cauterized. The child improved thereafter.

Primary squamous cell carcinoma (SCC) is extremely rare in the seminal vesicle. A 26-year-old male patient presented with complaints of difficulty in urination for 10 years and gross hematuria for 7 months. Ultrasonography and computed tomography imaging demonstrated a large mixed solid/cystic mass lesions in the rectovesical pouch. The mass was completely resected with the open approach and was verified as a primary SCC of the seminal vesicle by post-surgical histopathological examination. Pelvic metastases were detected 28 months after the surgery. This is the third reported case of primary SCC of the seminal vesicle, and the first one in a young patient. Early diagnosis and treatment are crucial for primary SCC of the seminal vesicle.

Summary— The endoscopic subtrigonal injection of a 6% aqueous phenol solution is an effective technique for denervating the bladder but its clinical usefulness is limited by unpredictable side effects. This study explored the possibility of making this procedure safer by comparing the neurolytic effects of different concentrations and carriers of phenol. Phenol in 2.5 and 5% solutions in three different carriers (water, glycerine and oil) was injected into the rectovesical pouch in 35 rats. After 3 weeks the bladders were excised and the effects on the density of acetylcholinesterase-positive nerves were assessed in each animal using morphometric techniques. The density of enzyme-containing nerves was reduced by 20% in the phenolised animals when compared with controls. This reduction was maximum when water was used as the carrier for either 2.5 or 5% phenol solutions.
