The posterior approach for groin hernia repair as popularized by Stoppa and Nyhus is one of the most solid repairs available. It requires a larger incision than the anterior approach, which has limited its use to recurrent and bilateral hernias. The endoscopic extraperitoneal herniorrhaphy (EEPH) accomplishes a similar repair via three minute incisions. This study suggests that EEPH is at least as safe and efficient as the open preperitoneal repair. Three hundred sixteen male patients underwent 405 hernia repairs by an endoscopic extraperitoneal approach. Ages ranged from 18 to 82 years old. There were 204 indirect, 182 direct, 13 pantaloon, and six femoral hernias. Eighty-nine were bilateral and 42 were recurrent. All repairs were done using polypropylene mesh. Follow-up has been achieved in 89% of patients and ranged from 7 to 50 months, with a median of 25 months. Seven patients (2.2%) required conversion to an open approach. Five recurrences have developed to date. Complications (5.7%) have included urinary retention, bladder injury, groin and/or scrotal hematoma, trocar site infection, lateral femoral cutaneous nerve neuralgia, and cardiac arrhythmia. Endoscopic extraperitoneal herniorrhaphy may provide an appropriate alternative to other methods of hernia repair when performed by experienced laparoscopists.

Endoscopic extraperitoneal herniorrhaphy (EEPH) was utilized to repair 326 groin hernias in 249 patients over a 32-month period. Nearly one in ten of the repairs was for a recurrent hernia. Several patients had contralateral hernias diagnosed only at the time of endoscopic examination. A recurrence rate of 1.6% and an overall complication rate of 5.2% are cited. After a plateau was reached on the surgeon's learning curve, various modifications in technique were implemented. Through these modifications, EEPH has become a safe, efficient, and standardized operation that can be performed with decreasing costs to the hospital and with increasing advantages to the patient.

Increasing experience among surgeons and a proliferation of endoscopic instrumentation have allowed a greater number of intraabdominal organs to be approached laparoscopically. Procedures once delegated to standard open technique are now attempted laparoscopically with increasing success. The following case report describes the laparoscopic removal of a large segment IV liver tumor. A review of the literature shows this to be one of the most complex hepatic lesions to be removed laparoscopically to date.

Extraperitoneal endoscopic pelvic lymph node dissection was performed in 60 patients for staging of organ-confined prostatic carcinoma. This procedure has significant advantages over the node dissection performed laparoscopically and should be adopted as the operative approach for staging of prostatic carcinoma.

The insufflated extraperitoneal approach to endoscopic pelvic lymph node dissection has been described as an alternative method of staging carcinoma of the prostate. There are several potential pitfalls in performing this approach, including the use of endoscopic instrumentation, trocars, insufflation equipment, and general anesthesia. In order to overcome potential problems associated with this surgical approach, a totally gasless extraperitoneal approach has been developed. This technique uses standard surgical instruments, does not use carbon dioxide to maintain the operative space, and uses general anesthesia. This procedure is more cost effective, since it uses no special instrumentation except the laprolift and laprofan to maintain the extraperitoneal cavity during lymph node dissection.
