Knotting Methods, Single-port Laparoscopic Surgery
Conditions
Brief summary
The surgeon's knot-tying technique plays a crucial role in the recovery of patients after single-port laparoscopy. Knot tying is very challenging in minimally invasive surgery and is a critical skill in advanced surgery. In this study, investigators introduce a new knotting technique, compare it with the traditional knotting technique in many aspects, and also discuss its application in the teaching of single-port laparoscopic knotting.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Accuracy of needle entry | through study completion, an average of 1 month | The needle stick should be in and out of the centre of the dot. The operator received 2 points if it was in the centre of the dot, 1 point if it deviated from the centre, and 0 points if it was outside the dot. |
| Stability of the knot | through study completion, an average of 1 month | The knot was required to be a surgical triple knot and should not have been a smooth knot or a loose knot. A normal knot received 2 points. A smooth knot received 1 point,and 0 points were awarded for a loose knot. |
| Tissue integrity | through study completion, an average of 1 month | The suture tissue should not be damaged or ruptured. The trainee received a score of two for integrity, 1 for a few cracks, and 0 for a complete fracture of the tissue. |
| Tightness of the tissue | through study completion, an average of 1 month | The tightness of the suture tissue indicated that the two sides of the sutured tissue were closely connected. The operator received 2 points if there was no gap between the two sides of the incision, 1 point for a few gaps, and 0 points for a totally loose suture. |
