Purpose:
The aim of this study was to compare the outcomes of laparoscopic appendectomy (LA) using purse string invaginating sutures (PS) with those using intracorporeal knotting (IK) or Hem-o-lock polymeric clips (HL).
Methods:
A total of 882 patients who underwent laparoscopic appendectomy from January 2015 to December 2017 were studied retrospectively. Of these, 538 patients used PS, 229 patients used IK and 115 patients used HL to close the appendiceal stump. Their demographic characteristics, intraoperative findings and postoperative complications were analysed retrospectively.
Results:
There were similar percentages of complicated cases in all the groups (21.7% in PS vs. 21.4% in IK vs. 24.3% in HL, p = 0.803). The mean length of hospital stay was shorter in PS group when compared to IK or HL group (3.72 + 2.35 in PS vs. 4.41 + 2.40 in IK, 4.43 + 2.66 in HL, p < 0.05) as well as lower ASA scores (1.7 + 0.6 in PS vs. 1.8 + 0.6 in IK vs. 1.7 + 0.6 in HL, p < 0.05). The overall complication rates for the PS, the HL and the IK groups were 12.1, 8.7 and 9.2%, respectively. The rate of wound infection was higher in PS group for uncomplicated appendicitis (5.0% in PS vs. 2.8% in IK and 1.1% in HL, p = 0.129). Furthermore, there were no differences in the rate of intra-abdominal infection among the groups in both uncomplicated and complicated cases.
Conclusions:
Based on our results, purse string suture failed to demonstrate better postoperative outcome in laparoscopic appendectomy and is no longer recommended by our institution as initial approach.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
