Abstract:
A 28-year-old female sustained an anorectal rupture after a fall from a jet ski. The rupture was sutured and a double-loop colostomy was created. Three months later, following a test of functional continence, the colostomy was removed. The patient recovered without complications and with preservation of faecal continence. During a fall from a jet ski at high speeds, the water behaves as a solid object that penetrates the body. The choice oftreatment depends on the anatomical location and extent of the injury, on the comorbidity, and on a possible delay in the presentation of the symptoms. Wearing ofwetsuits is proposed as a possible preventive measure.
