“…When angle between the working instruments is narrow, the ligation and suturing are very difficult to perform. A side winding intracorporeal suturing can overcome this difficulty [ 3 ]. Most importantly geometric factors of endoscopic reconstruction, such as optimal distances between the working trocars, length of instruments, and angles between the instruments and the object will make lot of difference in suturing.…”

Objectives. In our study we are aiming to analyse the learning curves in our surgical trainees by using two standard methods of intracorporeal knot tying. Material and Method. Two randomized groups of trainees are trained with two different intracorporeal knot tying techniques (loop and winding) by single surgeon for eight sessions. In each session participants were allowed to make as many numbers of knots in thirty minutes. The duration for each set of knots and the number of knots for each session were calculated. At the end each session, participants were asked about their frustration level, difficulty in making knot, and dexterity. Results. In winding method the number of knots tied was increasing significantly in each session with less frustration and less difficulty level. Discussion. The suturing and knotting skill improved in every session in both groups. But group B (winding method) trainees made significantly higher number of knots and they took less time for each set of knots than group A (loop method). Although both knotting methods are standard methods, the learning curve is better in loop method. Conclusion. The winding method of knotting is simpler and easier to perform, especially for the surgeons who have limited laparoscopic experience.

“…Therefore, in order to reduce operative time and complement the inexperience of younger surgeons in intracorporeal knotting, endoscopic suturing devices have been imported in clinical practice, with comparable results[44-46]. In SILS, the limited working area, the restricted vision, the minimization of the manipulation angle and the parallelization of the optics and hand instruments increases the overall difficulty level[47,48]. In single port fundoplication, intracorporeal suturing has been extensively performed[17,23,25,29,32] with various techniques, like side-winding and the utilization of articulating graspers and needle holders[49].…”

BACKGROUND Fundoplication, was first introduced as a surgical treatment method of gastroesophageal reflux disease. Consequently, several modifications of this method have been described, whereas laparoscopic fundoplication was recently introduced. Although single incision (SI) fundoplication was considered as an alternative to the conventional laparoscopic approach, several studies reported an increased operation duration, and high rates of multiport conversion and incisional hernia. AIM To provide a current overview of the technical variations and the postoperative outcomes of patients submitted to SI fundoplication. METHODS The present systematic review of the literature was designed and conducted on the basis of the PRISMA guidelines. A systematic screening of the electronic scholar databases (Medline, Scopus and Web of Science) was performed. RESULTS Literature search resulted in the identification of 19 studies. Overall, 266, 137 and 110 SI Nissen, Dor and Toupet fundoplications were reported, respectively. In the majority of the trials, standard laparoscopic instruments were used. The left liver lobe was displayed through the use of forceps, graspers, retractors, drains or even glue. Both intra-corporeal and extracorporeal suturing was described. Mean operative time was 136.3 min. Overall complication rate was 5.2% and the rate of incisional hernia was 0.9%. No mortality was reported. CONCLUSION Due to the methodological heterogeneity and the lack of high quality studies comparing multi to single access techniques and the several variations, we conclude that further well designed studies are necessary, in order to evaluate the role of SI fundoplication.

“…[ 4 ] Ekci B reported the intracorporeal “side winding” knot-tying technique and said even an inexperienced surgeon would be able to execute this knot safely, quickly, simply and cost effectively. [ 5 ] Of course, the extracorporeal knot-tying technique which was widely used in articular surgery can also be performed in LESS.…”

“…Therefore, it is meaningful to find a feasible and better knot-tying skill for the development of LESS. Several methods of creating knots representing by the one-handed knot tying technique,[ 4 ] the intracorporeal “side winding” knot-tying technique[ 5 ] and the extracorporeal technique with which knot-tying was accomplished “extracorporeally” using a knot-pusher, have been developed and used for LESS. All the methods reported have been considered be able to execute safely, simply and quickly.…”

INTRODUCTION:Knot tying is difficult but important for laparo-endoscopic single-site surgery (LESS). There are several techniques for LESS knot-tying. However, objective assessment of these skills has not yet been established. The aim of this study was to assess three different knot-tying techniques in LESS using mechanical methods.MATERIALS AND METHODS:The subject tied 24 knots, eight knots with each of the three techniques in an inanimate box laparoscopic trainer while the movements of their instruments were evaluated using a LESS mechanical evaluation platform. The operations were assessed on the basis of the time, average load of the dominant hand. Then, forces caused the knots to rupture were measured using a material testing system and used to compare the knots's strength.RESULTS:The intracorporeal one-hand knot-tying technique presented significantly better time and average load scores than the extracorporeal knot-tying technique (P < 0.01), and the intracorporeal side winding technique was more time and average load consuming in comparison to other techniques during the performance of knot-tying (P < 0.01). The intracorporeal one-handed knot-tying knots can tolerate better distraction forces compared with the intracorporeal side winding knot-tying knots and the extracorporeal knot-tying knots (P < 0.05).CONCLUSIONS:The intracorporeal one-hand knot-tying technique and knots showed better results than the intracorporeal “side winding” technique and the extracorporeal knot-tying technique in terms of the time, average load taken and the force caused the knot to rupture.
