Endometrial Evaluation Using Video-Assisted Hysteroscopy After Uterine Prolapse Management in a Mare.

Abstract: This case report describes the successful application of video-assisted hysteroscopy to evaluate endometrial recovery in a 6-year-old mare following treatment for complete uterine prolapse secondary to dystocia. Upon presentation, the uterus was manually reduced and supported with a Buhner's suture. A multimodal medical protocol, including broad-spectrum antibiotics, anti-inflammatory drugs and uterine lavage, was initiated. Five days after reduction, an endoscopic evaluation was performed using a dedicated videovaginoscope without uterine insufflation. The procedure provided high-resolution imaging of the uterine lumen and revealed a grossly intact endometrial surface without visual evidence of haemorrhage, necrosis or purulent discharge, confirming the successful resolution of the initial trauma. The technique allowed for a thorough and comfortable examination, offering a definitive assessment of superficial mucosal integrity that exceeds the capabilities of transrectal ultrasonography. The mare was discharged on Day 7 with restored reproductive health and subsequently conceived, maintaining a pregnancy confirmed at a 6-month follow-up. This case underscores the efficacy of a combined medical and mechanical approach to the treatment of uterine prolapse. Furthermore, it highlights the significant diagnostic value of video-assisted hysteroscopy as a valuable tool for post-treatment monitoring, allowing direct visual confirmation of endometrial health and thus contributing to the preservation of fertility after a severe obstetric event. This approach may serve as a routine diagnostic tool in equine postpartum reproductive evaluation.

Overview

  • This study reports the use of video-assisted hysteroscopy to assess the healing of the uterine lining in a mare after successful treatment of complete uterine prolapse caused by difficult birth.
  • The method provided detailed internal visuals of the uterus, confirmed recovery, and helped preserve fertility, leading to a successful pregnancy.

Background and Case Description

  • A 6-year-old mare experienced complete uterine prolapse secondary to dystocia, which means the uterus turned inside out and protruded, caused by complications during birth.
  • The uterus was manually repositioned (reduced) back inside the mare and stabilized using a Buhner’s suture, a surgical stitch aimed at supporting the uterus.
  • Following mechanical intervention, a medical protocol was put in place including:
    • Broad-spectrum antibiotics to prevent or treat infection
    • Anti-inflammatory drugs to reduce swelling and pain
    • Uterine lavage, which involves washing out the uterus to remove debris and reduce contamination

Diagnostic Technique: Video-Assisted Hysteroscopy

  • Five days post-treatment, the mare underwent an endoscopic evaluation of the uterus.
  • This was done using a specialized videovaginoscope designed for minimally invasive visualization without the need to inflate the uterus (no uterine insufflation), making the process more comfortable and less risky.
  • The high-resolution imaging allowed:
    • Direct visualization of the internal uterine lining (endometrium)
    • Assessment of tissue integrity to check for hemorrhage, necrosis (tissue death), and purulent (pus) discharge
    • Confirmation that the uterus had healed well without complications
  • This method provided diagnostic information beyond what is possible with more common techniques such as transrectal ultrasonography, which cannot assess the superficial mucosa in such detail.

Treatment Outcome and Follow-Up

  • The mare was discharged seven days after the prolapse reduction with restored reproductive health.
  • She later conceived successfully, with pregnancy confirmed at a six-month follow-up exam.
  • This confirmed the combined medical and surgical approach was effective not only in managing the prolapse but also in preserving fertility.

Significance and Implications

  • This case highlights:
    • The effectiveness of combining mechanical (manual reduction and suturing) and medical treatments for uterine prolapse.
    • The value of video-assisted hysteroscopy as a superior diagnostic tool for post-treatment uterine evaluation, allowing direct visual confirmation of endometrial health.
  • Because of its minimally invasive nature and the detailed information it provides, this technique may be recommended as a routine part of postpartum reproductive evaluation in horses, especially after severe obstetric complications.
  • Such monitoring can help veterinarians make informed decisions about the mare’s reproductive status and guide further treatment to maximize fertility preservation.
