“…One of the main theories regarding intestinal atresia is interruption of the blood supply to a segment of intestine and resulting in segmental atrophy in the embryonic course (12). Vascular insufficiency may be due to intussusception, volvulus, herniation or strangulation of the intestines during pregnancy period (17,18). This etiology is supported in experimental studies (19).…”

Atresia coli is a congenital defect that result in an inability to pass feces since birth. In the present study, type IIIa atresia coli (blind ends) was identified in a male Arabian foal with clinical signs of abdominal distension, colic, failure in defecation and depression. At necropsy, segmental agenesis affected left ventral and right dorsal colon. The dorsal right colons, transverse, small colon and rectum were atrophic with narrow lumen. The prognosis was poor in this case. Atresia coli was reported in the various breed of foals but it seems this is the first report in an Arabian breed foal.

Abstract:In the present report, clinical, pathological, and cytogenetic examinations of a one-day-old male German Holstein calf with atresia ani, hypospadia and rudimentary external genitalia (HYP-AA) and a six-months-old male German Holstein calf with hypospadia and rudimentary external genitalia (HYP) are presented. In the first case (HYP-AA), an anal orifice was missing. The urethra opened in the perineum. Consequently, the inguinal region was infiltrated with urine. A secondary finding was a vesicle at the anal area with a diameter of approximately 10 cm. Histopathological examination of the anal area of the HYP-AA-calf showed a necrotizing dermatitis with multifocal acute bleedings and diffuse oedema. In addition, an interstitial pneumonia and urethritis were identified. In the clinical examination of the second case (HYP), a penile and preputial aplasia, an incomplete ventral covering by skin and a bifid scrotum were found. Histopathological examination of the HYP-calf revealed a urethritis with epithelial hyperplasia in the urethra and a follicular hyperplasia of the lymph nodes. The HYP-calf had normally developed testicles. However, there was no active spermatogenesis. The inbreeding coefficient for the HYP-AA-calf was 0.684% and for the HYP-calf 5.273% and both affected calves had one ancestor in common, a Holstein bull used in artificial insemination. In conclusion the congenital anomalies of the two cases might be due to mutations transmitted by the common ancestor. İki Alman Holştayn Buzağıda Atresia Ani, Hypospadia ve Gelişmemiş Dış Genital Organlar OlgusuÖz: Bu raporda, klinik, patolojik ve sitogenetik muayenelerinin yapıldığı Atreziya ani, hypospadia ve gelişmemiş dış genital organlar ile karakterize bir günlük erkek Alman Holştayn buzağı (HYP-AA) ile Hypospadia ve rudumenter dış genital organlar ile karakterize altı aylık erkek bir Alman Holştayn buzağı (HYP) sunulmuştur. İlk olguda (HYP-AA) anüs oluşmamıştı. İdrar yolu perineuma açılmıştı; bunun sonucu olarak, kasık bölgesinden idrar süzülüyordu. İkinci bulgu olarak, yaklaşık 10 cm'lik bir çapa sahip olan anal bölgede bir vezikül oluşumu vardı. HYP-AA-nın anal bölgesinde yapılan histopatolojik incelemede multifokal akut kanama ve yaygın ödemli nekrotizan dermatit odaklar görüldü. Klinik olarak, interstisyel pnömoni ve üretritis tespit edilmiştir. İkinci olguda ise (HYP), bir penil ve prepusyal aplazi, ventral tarafı deri tarafından kaplanmamış bifid skrotum olgusu görüldü. HYP-nin histopatolojik incelemesinde üretra epitelinde hiperplazi ve lenf nodularında foliküler hiperplazi ve üretritis gözlemlendi. HYP-nin testisi normal gelişmiş, ancak aktif spermatogenez görülmedi. HYP-AA için akrabalık katsayısı % 0.684 ve HYP-için % 5.273 ve her iki buzağının babaları ortakdı. Sonuç olarak iki olguda da meydana gelen konjenital anomaliler ortak boğa tarafından iletilen mutasyonlara bağlı olabilir.

“…Although ileal atresia is the most common in calves, it is rare in other mammals such as lambs and kids (Brown et al, 2007). In calves, the most common sites have been reported to be the colon and anus followed by the jejunum and the ileum (Kilic & Sarierler, 2004;Brown et al, 2007;Lejeuner et al, 2011). The affected newborns may die due to autointoxication within a few days after birth (Radostitis et al, 2007).…”

“…In spite of the literature concerning colonic atresia suggesting a non-heritable trait, the etiopathogenesis of ileal atresia remains incompletely understood (Elsa & Onyeyili, 2004). However, there are two theories in this regard: one theory says that atresia arises from intra-uterine vascular insufficiency probably due to intussusception, volvulus, herniation or strangulation of the intestines during pregnancy period (Dawrant et al, 2008;Lejeuner et al, 2011;Gelberg, 2012). Moreover, the occlusion of the mesenteric vessels has been hypothesised as the etiology of ileal atresia in the medical literature (Husaric et al, 2012).…”

“…Another rare form of intestinal atresia with a genetic cause has also been described (Dawrant et al, 2008). In terms of genetic factors, atresia of the ileum in Swedish Highland cattle is inherited as autosomal recessive traits after inbreeding with a same bull (van der Gaag & Tibboel, 1980;Lejeuner et al, 2011). Dawrant et al (2008) demonstrated that injection of adriamycin leads to multiple malformations including multiple gastrointestinal atresia in an experimental study.…”

Atresia of the distal ileum concurrent with ileocaecal valve agenesis is one of the rare types of intestinal atresia with very few reports in the literature. We herein present a case of type II distal ileal atresia, ileocaecal valve agenesis and volvulus of the ileum and the terminal jejunum with a history of depression, anorexia and failure to pass meconium. On necropsy, volvulus of the ileum and the terminal jejunum was found. The ileum was distended, full of fluid and gas, and similar to a blind-end sac. The ileocaecal valve was absent and the ileum was attached to the caecum by a fibrous band. The caecum was atrophied and small. The distal segments of the intestine were smaller than normal. These findings revealed type II terminal ileal atresia simultaneously agenesis of the ileocaecal valve and intestinal volvulus probably secondary to atresia in a newly born goat kid.
