Background
In spite of the widespread use of laparoscopic appendectomy, there is an ongoing debate on the advantages of this method when compared to open appendectomy. In the evaluation of a postoperative procedure, long-term quality of life is essential.
Patients and methods
From 1999 to 2001, 493 patients diagnosed with acute appendicitis were operated in a German general district hospital and included in an observational study. In a median postoperative interval of 7 years, these patients were re-evaluated regarding their quality of life after surgery. A Short-Form 36 Health Survey (SF-36) questionnaire was applied to evaluate the general parameters of quality of life after surgery. This questionnaire was supplemented by an additional self-developed module referring to the appendectomy. The primary outcome was the recommendation of the experienced operating procedure to relatives and friends.
Results
A total of 243 patients underwent a laparoscopic procedure: 132 patients were re-evaluated (recovery rate 54%). In the open group, 250 patients were operated: 121 patients were re-evaluated (recovery rate 48%). The median interval from operation to evaluation was 7 years in the laparoscopic group and 7.7 years in the open group. For the primary outcome, patients with laparoscopic appendectomy would significantly more often recommend the procedure than patients with the open operation method. For secondary outcomes, the cosmetic results were judged significantly more favourably in the laparoscopic group. The eight scaled scores of the SF-36 questionnaire did not differ significantly between the two groups. Four patients of the open group and nine patients of the laparoscopic group (including one converted procedure) needed a reoperation because of incisional hernia, adhesions and late infections.
Conclusion
Patients after laparoscopic appendectomy show a higher degree of satisfaction with their body and their scar than patients after open appendectomy.
