Long-term management of sabulous cystitis in five horses.

Five horses with sabulous cystitis were managed for up to three years. They were treated by emptying the bladder through a urinary catheter and saline lavage with cytoscopic guidance to remove residual sabulous material. The cystitis was treated with antimicrobial and anti-inflammatory medications, and bethanechol chloride was also administered. Frequent catheterisation and emptying of the bladder was an alternative to regular cystoscopic examination with saline lavage but it resulted in the development of a urethral stricture in one case. Four of the horses returned to work and one was retired owing to persistent incontinence.

End-to-end jejuno-ileal anastomosis following resection of strangulated small intestine in horses: a comparative study.

REASONS FOR PERFORMING STUDY: Small intestinal resection and anastomosis is a relatively common procedure in equine surgical practice. This study was designed to test objectively the subjective opinions of surgeons at the Liphook Equine Hospital that an end-to-end jejuno-ileal anastomosis (JIA) is an effective and clinically justifiable procedure, contrary to conventional recommendations. HYPOTHESIS: An end-to-end JIA carries no greater risk of morbidity and mortality than an end-to-end jejunojejunal anastomosis (JJA). METHODS: A retrospective observational study was performed on a population of 100 horses that had undergone small intestinal resection and end-to-end anastomosis. Two groups were identified; Group 1 (n = 30) had undergone an end-to- end JIA and Group 2 (n = 70) an end-to-end JJA. The 2 populations were tested for pre- and intraoperative comparability and for their equivalence of outcomes. RESULTS: The 2 populations were comparable in terms of their distributions of preoperative parameters and type of lesion present. The observations used as outcome parameters (incidence risk of post operative colic, incidence risk of post operative ileus, duration of post operative ileus, rates of functioning original anastomoses at the time of discharge and at 12 months, survival rates at 6 months and 12 months) were equivalent between the 2 groups. CONCLUSION: End-to-end JIA carries no greater risk of morbidity and mortality than an end-to-end JJA. POTENTIAL RELEVANCE: Surgeons faced with strangulating obstructions involving the jejuno-ileal junction in which there remains an accessible length of viable terminal ileum may reasonably perform an end-to-end JIA. This has the potentially significant advantage over a jejunocaecal anastomosis of preserving more anatomical and physiological normality to the intestinal tract. The study was, however, relatively small for an equivalence study and greater confidence would be gained with higher numbers.
