Use of a Barbed Knotless Suture for Laparoscopic Ablation of the Nephrosplenic Space in 8 Horses.

This study evaluates the efficacy of a knotless suture used for laparoscopic closure of the nephrosplenic space in horses, considering its utility and properties like the duration of surgery, width of closure, and the tissue healing progression.

Research Methodology

• The subject of this research were horses without any history of abdominal surgery, thereby taking out the bias of any prior wound or surgical repair interference.
• The procedure involved laparoscopic closure of the nephrosplenic space which involves a minimal invasive surgery guided by a camera.
• The technique specifically involved a unidirectional, barbed 0 metric absorbable suture made from the copolymer of glycolic acid and trimethylene carbonate.
• Special mention of suturing in a cranial-to-caudal direction in a simple continuous fashion outlined the meticulously executed technique.
• Post-surgery, reassessment was done in two horses using laparoscopy and in the remaining six through necropsy, evaluating the lengths of closure and the nature of healed tissue.

Research Findings

• The quantified durations pointed towards a variable duration of surgery. The total surgery time varied between 65-167 minutes with an average of 89.6 minutes denoted with the standard deviation of 22.6.
• The suturing time within these surgeries also oscillated between 30-65 minutes, with an average close to 40 minutes.
• Post-operative checks via laparoscopy and necropsy were performed over a range of days.
• Closure measurement showed a length of 12-14 cm.(of sutures?) This indicates the extent of the wound or injury that needed the suturing strategy in the horses.
• Post-operative healing showed mature fibrous tissue formation as the horses recovered. This provides reassurance of the healing power of the body post the laparoscopic procedure.
• The absence of any residual suture material in the checked horses highlighted the absorbable property of the sutures employed.

Conclusions

• The results pointed towards the utility of barbed knotless sutures for laparoscopic closure of nephrosplenic space in horses.
• The study provided insights into the potential usage of this type of suture but also specified the need for further research to maximise the clinical efficacy and understand its application in clinically affected horses.
