RESUMEN
Many techniques for laparoscopic appendectomy have been proposed with few comparative studies. We performed a retrospective review of all patients undergoing laparoscopic appendectomy for uncomplicated appendicitis from 2006 to 2011. Techniques were: (1) transection of the mesoappendix and appendix with a single staple line (SSL); (2) transection of the mesoappendix and appendix with multiple staple lines (MSL); and (3) transection of the mesoappendix with ultrasonic shears and the appendix with a single staple line (USSL). A total of 565 cases were reviewed (149 SSL, 259 MSL, and 157 USSL). Patients treated with the SSL technique had decreased operative duration (P<0.001) and length of stay (P=0.003) despite equivalent disease presentations. Multivariate analysis demonstrated decreased operative duration with the SSL technique (P=0.001). Use of a SSL for transection of the mesoappendix and appendix is both a safe and efficient technique that results in reduced operative duration with excellent surgical outcomes.
