A 4-year-old intact female Maltese was referred to the Animal Medical Center of Chonbuk National University with a history of consistent fecal incontinence over 4 months following sacculectomy surgery. We suspected that anal sacculectomy resulted in loss of the external anal sphincter. On physical examination, the external anal sphincter muscle on the left side was intact, while the external anal sphincter muscle on the right side could not be detected and exhibited severe laceration. To repair the defect, the left semitendinosus muscle was transposed around the anus. The left semitendinosus muscle was isolated and transected near the stifle, reflected dorsally and passed around the ventral rectum into the pararectal fossa. Care was taken to preserve the integrity of the vasculature and nerve supply. The muscle was secured dorsally with simple interrupted sutures to the levator ani and coccygeus muscles to simulate the external anal sphincter. Nine days after surgery, the dog was defecating normally with no evidence of incontinence. The use of semitendinosus muscle flaps is a good option for the treatment of fecal incontinence secondary to loss of sphincter muscle in dogs.

Background: The management of feline hindlimb full-thickness skin defects is challenging. On the other hand, the use of a semitendinosus (ST) myocutaneous flap for their coverage has not been reported. Objectives: To describe the ST flap and compare it with second intention healing for managing hindlimb full-thickness skin defects. Methods: In 12 purpose-bred laboratory domestic short-haired cats, two wounds were made on each tibia. The wounds in group A (n = 12) were covered with ST flaps, and those in group B (n = 12) were left to heal by second intention. In both groups, clinical assessment scoring and planimetry were performed between one-30 d postoperatively. Computed tomography-angiography (CTA) was performed on days zero, 10, and 30, and histological examinations were performed on days zero and 14 and at 6 and 12 mon postoperatively. Results: Statistically significant differences in the clinical assessment scores were observed between groups A and B on days 14 (p = 0.046) and 21 (p = 0.016). On the other hand, the time for complete healing was similar in the two groups. CTA revealed significant differences in the muscle width (day 0 compared to days 10 and 30 [p = 0.001, p = 0.026, respectively], and days 10 to 30 [p = 0.022]), ST muscle density, and the caliber of the distal caudal femoral artery and vein (day 0 compared to day 10 [p < 0.001], and days 10 to 30 [p < 0.001]). Histologically significant differences in inflammation, degeneration, edema, neovascularization, and fibrosis were observed on day 14 compared to zero and 6 mon, but no differences were found between the time interval of 6 and 12 mon. Conclusions: An ST flap can be used effectively to manage hindlimb full-thickness skin defects.

체중 3.5 kg 11년령 요크셔 테리어가 대변실금, 뒤무직(이급후증), 회음부의 종괴를 동반하는 증상으로 내원하였다. 신체 검사상 비대 유선, 질 분비물과 정복이 가능한 회음부의 종괴가 발견되었다. 임상증상과 방사선검사를 바탕으로 배쪽 양측 회음 허니아와 자궁축농증으로 진단하였다. 자궁난소 적출술 후 양측 회음 허니아는 결장 고정술과 방광 고정술 후 반힘즐 근육 전위술을 이용하여 정복하였다. 수술 후 방사선과 컴퓨터 단층 촬영 검사상에 배쪽 양측 회음 허니아의 정복을 확인할 수 있었다. 술 후 10일째 정상적인 활동을 보였고 1년 동안에 검사상 수술과 관련된 부작용은 관찰되지 않았다. 배쪽 양측 회음 허니아는 결장 고정술과 방광 고정술 후 반힘즐 근육 전위술을 이용하여 성공적으로 치료 되었다.
