ObjectiveTo compare the advantages and disadvantages of laparoscopic versus open appendectomy in patients with chronic appendicitis.MethodsTwo hundred twenty- four patients were divided into laparoscopic group (n=98) and open appendectomy group (n=126) according to individual willing. Prospective non- randomized study was performed to compare the operative time, operative bleeding, hospitalization time, the discovery and management concerned in operation. Abdominal pain in these chronic appendicitis cases was followed up.ResultsThe operative time was (54.8+/-21.8) min in open group and (51.8+/-18.0) min in laparoscopic group (t=0.80,P > 0.05). The operative bleeding was (18.6+/-23.3) ml in open group and (9.8+/-4.7) ml in laparoscopic group (t=3.13, P < 0.05). The hospitalization time was (8.9+/-5.3) d in open group and (6.8+/-3.0) d in laparoscopic group (t=2.66,P < 0.05). Twenty- five cases had abdominal adhesion in laparoscopic group, including 9 cases of adhesion around appendix, 6 cases of adhesion between ileocecum and anterior or lateral abdominal wall, 4 cases of adhesion between epiploon and abdominal wall or intestines, 6 cases of adhesion around colon and others. All adhesion had been dissected. Fourteen cases adhesion around appendix had been discovered in 126 cases of open group and dissected (chi(2) =7.95,P < 0.05). In follow- up research, 24 cases still had chronic abdominal pain in 98 case of open group, and 9 cases had chronic abdominal pain in 87 of laparoscopic group, the difference was significant (chi(2)=6.29,P < 0.05).ConclusionThe laparoscopic appendectomy possesses more advantages in treating chronic appendicitis and can decrease the incidence of chronic abdominal pain after operation.
