“…For security in case a ligature should slip we standardly double ligate the cord during castration. The subcutaneous tissue, fascia and skin were closed in two layers as recommended [ 3 ] using either SS or KBS. The fascia beneath the skin and the subcutaneous tissue were closed in one layer and the skin was closed in another layer.…”

Bidirectional knotless barbed versus conventional smooth suture for closure of surgical wounds in inguinal castration in horses

et al. 2020

Background Castration of the stallion is one of the most frequently performed surgical procedures in the horse. Recently barbed suture materials for surgical wound closure were introduced to the market with manufacturers claiming that these sutures enhance speed and security as they eliminate the need to tie knots. Recently, it has been suggested that this type of suture may increase postoperative complications. This study aimed at investigating and comparing a bidirectional absorbable knotless barbed suture (KBS) to a conventional smooth suture (SS) for wound closure of inguinal castrations in the horse. This was done by evaluating short-term and post-discharge complications and by comparing the time spent on suturing the surgical wounds after bilateral inguinal castration, which was performed on 45 horses undergoing castration at The Large Animal Teaching Hospital at University of Copenhagen from September 2017 to May 2019. Results Short-term complications were few; at 24 h minor swelling occurred in 29 and 33% of horses sutured with KBS and SS respectively and cutaneous dehiscence during recovery occurred in two horses of each group. Post-discharge follow-up revealed that three horses needed veterinary attention for treatment of complications (scrotal swelling ( n = 1, KBS); wound exudation ( n = 1, SS) and wound dehiscence after return to pasture ( n = 1, SS)). Wound closure was achieved 6 min faster with KBS than with SS ( P < 0.0001). Conclusions Use of the KBS suture did not result in increased occurrence of postoperative complications. Wound closure was faster with KBS than with SS in equine bilateral inguinal castration. Our results show that KBS can safely be used in the horse following bilateral inguinal castrations without adverse effects and with a reduction in suturing time.

“…Castration is associated with postoperative complications such as swelling/oedema, haemorrhage, infection, septic funiculitis of the stump of the cord eventually resulting in ascending peritonitis, omental herniation and eventration [1, 2]. While these acute or short-term complications are rather well-investigated, late complications are less studied.…”

“…Horse owners may present geldings with rather vague signs occurring after the castration, such as changed behaviour, gait and urination habits or decreased riding performance. While there are few studies on these problems, it is generally accepted that soreness related to the post-operative scar may be as a source of gait modification [1]. Treatment includes surgical removal of massive scarring tissues, including larger or smaller areas of fibrous tissues, at the castration site.…”

Neuromas at the castration site in geldings

2019

View full text Add to dashboard Cite

Background Inguinal pain, unexplained hind limb lameness, back pain or behavioural problems in geldings could be attributable to painful neuromas that develop as a consequence of crushing and severing the testicular nerves during castration. The presence of neuroma in this anatomical location has never been reported, hence the knowledge of possible clinical relevance is limited. The aim of this study was to histologically investigate the testicular nerves at the castration site in geldings for the presence of neuromas. Proximal spermatic cord remnants were collected from 20 geldings admitted to routine post mortem examination for various reasons. The time of castration was unknown, but it had not been performed during the last year. Spermatic cord specimens were immersed in 10% formalin, trimmed, dehydrated, embedded in paraffin, sectioned and stained with haematoxylin and eosin (HE) for light microscopy. Identification of nerve tissue was done by immuno-localization of nerve specific enolase (NSE). Results Neuromas were found in 21 spermatic cords from 13 geldings and were bilateral in eight of the horses. The neuromas consisted of areas with small groups of non-neoplastic proliferations of peripheral neural tissue. The tissue included neurofilaments and Schwann cells, intermingled or surrounded with, epineural, perineural and endoneural fibrous tissue. The neural tissue immunostained positive with NSE. Conclusions This study showed neuromas of the remnant testicular nerves at the site of castration. Further studies are required to establish if these neuromas in the castration site are painful and if certain castration methods promote their formation. Future studies should also investigate the clinical consequence of these neuromas for the individual horse.

A 400 kg, male, adult cob pony presented with a history of stallion‐like behaviour without testicles palpable. The blood oestrone sulphate level was 4.90 ng/ml, consistent with cryptorchidism (0.1–10.0 ng/ml; IDEXX). Age was estimated at 8 years by dentition. Previous veterinary treatment history was unavailable. Examination under general anaesthesia found no evidence of prior surgical castration. Investigation of the inguinal region was unremarkable with no evidence of an inguinal extension of the gubernaculum testis or vaginal process on either side. Exploratory laparotomy of the right abdomen revealed a cystic, 5 × 8 cm mass with homogenous tapering stalk. This was removed by emasculation. Histological examination identified the mass as a benign testicular teratoma. Blood anti‐Mullerian hormone 5 days after the surgery measured 0.9 ng/ml. The pony made a full recovery and the owner reported the behavioural issues have resolved.
