A comparison of epidural versus general anesthesia for outpatient endoscopic preperitoneal herniorrhaphy

To study the efficacy of epidural versus general anesthesia on length of stay, patient recovery and anesthetic-related complications in patients undergoing endoscopic preperitoneal herniorrhaphy.

One hundred sixty-seven consecutive patients undergoing endoscopic preperitoneal herniorrhaphy from July, 1994, to August, 1995, were retrospectively studied. A total of 243 herniorrhaphies were performed. Four patients required conversion of epidural anesthesia to general anesthesia because of inadequate sensory blockade (67/71; 94% success rate). One-hundred-forty-eight patients were available for review. Sixty-seven patients underwent successful epidural anesthesia during the case, while 81 patients were managed with general anesthesia.

Thirty patients (37%) receiving general anesthesia required interventions for nausea compared to only six patients (9.0%) in the epidural anesthesia group (p < 0.001). Thirty patients (37%) in the general anesthesia group required intervention because of complaints of pain, compared to 13 (19.4%) in the epidural group (p < 0.05). There were no differences between the two groups for length of stay in OR, PACU, or total hospital times.

The use of epidural anesthesia during the performance of endoscopic preperitoneal herniorrhaphy was associated with a decrease in the incidence of postoperative pain and nausea. The technique was successful in 94% of the cases in which it was used. Epidural anesthesia is recommended as an effective alternative to general anesthesia for the performance of outpatient endoscopic preperitoneal herniorrhaphy.
