[Laparoscopic versus conventional appendectomy]
Abstract:
From 1/1995 to 8/1997 857 appendectomies were observed in a prospective study. From then on in our clinic has done more laparoscopic then conventional operations, and has developed in the years before a permanent laparoscopic team. For all operations resterilized MIC-instruments are used. Preparation is done with bipolaric instruments and scissor, the appendix stump is supplied a with Röder-sling. The expensive Endo-GIA was used only 3x, if the coecumpole was also inflamed. Because of the fantastic intraabdominal view additional findings quickly be recognized through the laparoscopic method. It was then possible, to plan the therapeutic management exactly. Also variations of the appendix-position are seen clearly and can be operated on without other incisions. There is no significant difference in time between the two methods as we have seen here in practice (35.3 minutes for the conventional and 43.8 for the laparoscopic operation)--they will assimilate, when the surgeon is routine. Fat and muscular patients profit definitely. The problems of wound infection have been rarely observed by the laparoscopic operation. The rate of intraabdominal abscesses was 1.9% and therefore higher as by the conventional method (0.2%). This could be reduced during the period of the study, because we now often lavage and drain. We think that there are no surgical opponent indication to the laparoscopic appendectomy. The reliable conventional technique has to be an obligate technique also in future.
Insights
Laparoscopic appendectomy offers excellent visualization and fewer wound infections compared to conventional methods. While initial abscess rates were higher, improved techniques reduced this risk, making it a viable surgical option.
Area of Science:
- General Surgery
- Minimally Invasive Procedures
Background:
- The study prospectively observed 857 appendectomies between January 1995 and August 1997.
- The clinic increasingly adopted laparoscopic appendectomies, developing a dedicated surgical team.
Purpose of the Study:
- To compare the outcomes of laparoscopic appendectomy with the conventional technique.
- To evaluate the effectiveness and safety of laparoscopic appendectomy in a clinical setting.
Main Methods:
- Prospective study design observing 857 appendectomies.
- Standardized preparation using bipolaric instruments, scissors, and Röder-sling for the appendix stump.
- Use of minimally invasive surgery (MIS) instruments, with Endo-GIA reserved for specific cases.
Main Results:
- Laparoscopic appendectomy provides superior intra-abdominal visualization, aiding in the detection of additional findings and precise therapeutic planning.
- Operating times were comparable between methods (conventional: 35.3 min, laparoscopic: 43.8 min), with convergence expected upon surgeon proficiency.
- Laparoscopic approach showed significantly fewer wound infections but a higher initial rate of intra-abdominal abscesses (1.9% vs. 0.2%), which was reduced through improved lavage and drainage techniques.
Conclusions:
- Laparoscopic appendectomy is a safe and effective procedure with no absolute contraindications.
- The technique offers benefits, particularly for obese or muscular patients, due to enhanced visualization and reduced wound complications.
- Conventional appendectomy remains a reliable technique, essential for future surgical practice.
