[Laparoscopic appendectomy with mini-instruments].

Area of Science:

• Minimally Invasive Surgery
• Gastrointestinal Surgery
• Surgical Technology

Background:

• Laparoscopic appendectomy is a standard procedure for appendicitis.
• Mini-instrumentation offers potential advantages in reducing surgical trauma and improving cosmesis.
• Standardization of techniques is crucial for reproducible outcomes.

Purpose of the Study:

• To present prospective data on laparoscopic appendectomy using mini-instruments.
• To describe a standardized surgical technique for this procedure.
• To evaluate the safety, efficacy, and cosmetic results of mini-instrument laparoscopic appendectomy.

Main Methods:

• Prospective data collection from 35 patients undergoing mini-instrument laparoscopic appendectomy (01/00-12/01).
• Standardized technique utilizing a 12 mm umbilical trocar and two suprapubic mini-trocars.
• Preparation and manipulation with mini-instruments guided by a 10 mm/30-degree optic; stapling and ligation via the umbilical trocar.

Main Results:

• 35 patients (33 female, mean age 23.4 years, mean BMI 21.1) underwent the procedure.
• Mean operation time was 41.1 minutes, with a mean post-operative stay of 3.3 days.
• No intra- or post-operative complications were observed; one trocar exchange occurred for improved visualization.

Conclusions:

• Laparoscopic appendectomy with mini-instruments is feasible and safe for experienced surgeons in slender patients with low-grade appendicitis.
• The technique yields excellent cosmetic results without an increased complication rate.
• This approach represents a viable option for specific patient populations undergoing appendectomy.
