Securing the appendiceal stump with the Gea extracorporeal sliding knot during laparoscopic appendectomy is safe and economical.

BACKGROUND

Laparoscopic appendectomy (LA) has become very popular. One criticism of this approach is the high cost of the disposable equipment such as the linear stapler. An alternative would be suture ligation of the appendiceal base. To prove the safety of the Gea extracorporeal sliding knot (GESK) for closure of the stump after LA, a retrospective study was conducted.

METHODS

For this study, 63 LA procedures performed by one surgeon using the Gea knot (group A) were reviewed and compared with 63 LA procedures performed by two other surgeons (group B) using the linear stapler. The GESK is created with 0-prolene in the manner already described. The main variable was the presence or absence of blowout, leak, or fistula from the appendiceal stump. The secondary variables were abdominal abscess, wound infection, and need for readmission or reoperation. The results were analyzed using the appropriate statistical methods.

RESULTS

Both groups were similar in terms of age, gender, and pathologic diagnosis. No patient in group A or B experienced a colonic fistula, stump blowout, or leak. In group A, one patient experienced interloop abscesses. There were two wound infections. In group B, one patient experienced a wound infection, and another patient had a wound dehiscence of the umbilical port, which required reoperation. No statistical differences were noted between the two groups.

CONCLUSIONS

There are surgeons who routinely use sutures to secure the stump of the appendectomy. This study aimed to demonstrate that the GESK is as secure as the stapler for closure of the appendiceal stump. The GESK could be passed through a 5-mm trocar, potentially avoiding complications of a larger trocar site. The GESK seems to be an economic and safe alternative to the stapler.
