[Complicated acute apendicitis. Open versus laparoscopic surgery].

INTRODUCTION

Although laparoscopy has become the standard approach in other procedures, this technique is not generally accepted for acute appendicitis, especially if it is complicated due reports on the increase in intra-abdominal abscesses.

OBJECTIVE

The purpose of this study was to evaluate the morbidity in a group of patients diagnosed with complicated apendicitis (gangrenous or perforated) who had undergone open or laparoscopic appendectomy.

MATERIAL AND METHOD: We prospectively studied 107 patients who had undergone appendectomy for complicated appendicitis over a two year period. Mean operation time, mean hospital stay and morbidity, such as wound infection and intra-abdominal abscess were evaluated.

RESULTS

In the group with gangrenous appendicitis morbidity was significantly lower in laparoscopic appendectomy group (p = 0.014). Wound infection was significantly higher in the open appendectomy group (p = 0.041), and there were no significant differences in intra-abdominal abscesses (p = 0.471). In the perforated appendicitis group overall morbidity (p = 0.046) and wound infection (p = 0.004) was significantly higher in the open appendectomy group. There were no significant differences in intra-abdominal abscesses (p = 0.612).

CONCLUSION

These results suggest that laparoscopic appendectomy for complicated appendicitis is a safe procedure that may prove to have significant clinical advantages over conventional surgery.
