Initial Experience with Magnet-Assisted Single Trocar Appendectomy in Children

Abstract

MAST appendectomy is safe and effective in children. Magnetic instruments provide excellent triangulation and improve ergonomics. This technique uses a single 12-mm trocar and can be performed without the aid of a surgical assistant.

Systematic review and meta-analysis of single-incision versus conventional laparoscopic appendectomy in children

“…This makes SILA a more challenging technique, especially in the much smaller abdominal cavities of children. Padilla et al [43] reported a modified SILA technique in which magnetic instruments were used to provide excellent triangulation and to improve ergonomics; this technique may eventually play a role in the reduction of the duration of surgery. Additionally, it should also be noted that the ability to overcome the initial steep learning curve associated with the adoption of a new surgical technique as well as practice and experience with single-incision laparoscopic surgeries could also assist in the reduction of the operation time.…”

Single-Port Laparoscopic Interval Appendectomy for Perforated Appendicitis With a Periappendiceal Abscess

“…However, in the current study, the problems anticipated for the loss of triangulation were overcome by using a mini-laparoscopic instrument in complicated cases. To overcome the technical challenges associated with the use of single-port or reduced-port laparoscopic surgery, Lasheen et al [ 25 ] used a spiral needle to facilitate the procedure in two-port surgery for appendectomy, and Padilla et al [ 26 ] reported SPLS using a magnet-assisted single trocar for adequate exposure. Moreover, Ates et al [ 27 ] introduced a percutaneously-inserted suture from the right lower quadrant into the peritoneal cavity during SPLS for an appendectomy.…”
