Appendectomy in the pre- and postlaparoscopic eras

The role of laparoscopic appendectomy remains controversial since many authors have suggested that overall morbidity is primarily a function of the degree of appendicitis rather than the operative approach. We have reviewed our appendectomy experience to determine the advantages and/or disadvantages of the laparoscopic technique in cases of acute appendicitis, and furthermore to ascertain whether the extent of disease should affect the surgical approach used. Data were accumulated for all 1158 patients who underwent appendectomy at a single institution during the following three time periods that span the pre- and postlaparoscopic eras: period I (1987 to 1990), period II (1991 to 1993), and period III (1994 to 1997). Cases were categorized with regard to pathologic findings and operative approach (i.e., open or laparoscopic appendectomy). The percentage of appendectomies performed laparoscopically increased with time (0%, 27%, and 79% for periods I, II, and III, respectively). Overall, the total operating room time was slightly shorter for laparoscopic compared to open appendectomy (99 vs. 102 minutes; P
