Uterine horn intussusception in immediate post-partum in a Pomeranian Spitz dog.

A 2-year-old Pomeranian-Spitz dog (5.8 kg) was admitted with symptoms of uterine prolapse and lethargy 1 day after whelping three puppies. The prolapsed uterus was corrected, but the next day, prolapse reoccurred. To fix the cervix to the abdominal wall, the dog underwent a surgery operation where intussusception in the left horn of the uterus was found. Ovariohysterectomy was performed as the treatment of choice. The diagnosis of intussusception is challenging, and exploratory laparotomy is the reliable diagnostic approach. Although uterine intussusception is rare, it should be one of the important considerations in dogs within the post-partum period.

Colonic gastrointestinal stromal tumor (GIST) presenting with colocolonic intussusception: A rare case report.

An 8-year-old spayed female British bulldog was presented with vomiting, hyporexia, and large-bowel diarrhea. Abdominal ultrasound revealed a focal colonic mass with an intussusception located immediately oral to the mass. The intussusception encompassed the ascending and transverse colon and was non-reducible. Colonic resection and anastomosis were completed to include the intussusception and colonic mass. Histopathological examination of the mass demonstrated a spindle cell neoplasm arising within the muscular wall of the intussuscepted segment that obliterated normal architecture. Mild-to-moderate cytoplasmic immunoreactivity of the tumor cell population for CD117 and smooth muscle actin was consistent with a diagnosis of a gastrointestinal stromal tumor. The dog described herein remains alive and free of progressive disease at the time of writing. Key clinical message: The entire gastrointestinal tract should be evaluated in any animal with gastrointestinal symptoms. A gastrointestinal stromal tumor remains a plausible differential diagnosis, regardless of the intestinal segment affected, and tumorassociated intussusception is a rare but urgent clinical finding.

Tumeur stromale gastro-intestinale du côlon (GIST) présentant une invagination colocolique : un rapport de cas rare. Une femelle bouledogue anglais stérilisée de 8 ans a présenté des vomissements, une hyporexie et une diarrhée d'origine du gros intestin. L'échographie abdominale a révélé une masse colique focale avec une invagination située immédiatement oralement à la masse. L'intussusception englobait le côlon ascendant et transverse et était non réductible. La résection colique et l'anastomose ont été réalisées pour inclure l'intussusception et la masse colique. L'examen histopathologique de la masse a révélé un néoplasme à cellules fusiformes apparaissant dans la paroi musculaire du segment invaginé qui a oblitéré l'architecture normale. L'immunoréactivité cytoplasmique légère à modérée de la population de cellules tumorales pour le CD117 et l'actine des muscles lisses étaient compatibles avec un diagnostic de tumeur stromale gastro-intestinale. Le chien décrit ici est toujours vivant et exempt de maladie évolutive au moment de la rédaction.Message clinique clé :L'ensemble du tractus gastro-intestinal doit être évalué chez tout animal présentant des symptômes gastrointestinaux. Une tumeur stromale gastro-intestinale reste un diagnostic différentiel plausible, quel que soit le segment intestinal atteint, et l'intussusception associée à la tumeur est une constatation clinique rare mais urgente.(Traduit par Dr Serge Messier).

Colonic Hamartomatous Ganglioneuromatosis in a 4 Mo Old Puppy.

A 4 mo old male goldendoodle puppy was evaluated for chronic hematochezia with a history of recurrent rectal prolapse and tenesmus. A colo-colonic intussusception was diagnosed via abdominal imaging. Surgery was elected to reduce the intussusception, wherein a colonic mass was discovered. Colonic resection and anastomosis was performed, and the tissue were submitted for histopathological examination. The puppy was diagnosed with colonic hamartomatous ganglioneuromatosis based on the presence of markedly hyperplastic submucosal and myenteric plexi with infiltration and expansion of the mucosa and submucosa by Schwann cells and neuronal cell bodies. Ganglioneuromatosis is a rarely reported entity in the veterinary literature, and limited clinical follow up data is available for described cases. In humans, ganglioneuromatosis is associated with a PTEN genetic mutation, which confers increased susceptibility to the development of neoplasia of endocrine organs. Approximately 1 yr after the operation, this puppy appeared clinically normal with no abnormalities on repeated imaging. This case report describes the clinical presentation, surgical treatment, and histologic features of colonic hamartomatous ganglioneuromatosis with 1 yr postoperative clinical follow up data in a dog. Although uncommon, ganglioneuromatosis should be considered as a differential diagnosis list as a cause of gastrointestinal masses in puppies and young dogs.

A case of colonic-colonic intussusception in a dog secondary to lymphoma treated with colonic resection and anastomosis.

A 2-year-old castrated male Great Dane crossbreed dog was presented with a history of diarrhea and suspected intussusception. Abdominal ultrasound revealed a colonic-colonic intussusception. The gastrointestinal tract was explored, and an approximately 5-cm intussusception was discovered mid-colon. All other gastrointestinal structures were normal in appearance. The intussusception could not be reduced manually. A colonic resection and anastomosis were performed together with a left-sided incisional colopexy. The dog recovered from surgery and histopathology revealed the intussusception to be secondary to large cell transmural lymphoma. Sections from the surgical margins revealed proliferation of fibrovascular tissue along the serosal surface segmentally, but no neoplastic cells were identified. The dog was subsequently treated with chemotherapy consisting of doxorubicin and prednisone. No evidence of disease recurrence was noted on ultrasound 9 months after surgery. Approximately 2 years after surgery, the dog is noted to be clinically normal at home with no abnormal findings on physical examination. A complete blood (cell) count and chemistry obtained at this time revealed no significant abnormalities besides mild azotemia. Additional restaging was declined by the owner.

Un cas d'intussusception colon-colon chez un chien secondaire à un lymphome traité par résection c olonique et anastomose. Un grand danois croisé mâle castré âgé de 2 ans a été présenté avec des antécédents de diarrhée et une suspicion d'intussusception. L'échographie abdominale a révélé une intussusception colon-colon. Le tractus gastro-intestinal a été exploré et une intussusception d'environ 5 cm a été découverte au milieu du côlon. Toutes les autres structures gastro-intestinales avaient un aspect normal. L'intussusception n'a pas pu être réduite manuellement. Une résection colonique et une anastomose ont été réalisées avec une colopexie incisionnelle du côté gauche. Le chien a récupéré de la chirurgie et de l'histopathologie a révélé que l'intussusception était secondaire à un lymphome transmural à grandes cellules. Des sections des marges chirurgicales ont révélé une prolifération de tissu fibrovasculaire le long de la surface séreuse de manière segmentaire, mais aucune cellule néoplasique n'a été identifiée. Le chien a ensuite été traité par une chimiothérapie composée de doxorubicine et de prednisone. Aucun signe de récidive de la maladie n'a été noté à l'échographie 9 mois après la chirurgie. Environ 2 ans après la chirurgie, le chien est cliniquement normal à la maison sans résultats anormaux à l'examen physique. Une numération sanguine (cellule) complète et l'analyse chimique obtenues à ce moment n'ont révélé aucune anomalie significative outre une légère azotémie. Une nouvelle restadification a été refusée par le propriétaire.(Traduit par Dr Serge Messier).

Ultrasonographic and computed tomographic features of a true gastro-gastric intussusception with concurrent foreign bodies in a dog.

A 2-year-old intact male Cane Corso dog was presented for acute weakness, vomiting, and diarrhea. Abdominal ultrasound revealed the stomach had severe wall edema and a target appearance. Computed tomography was consistent with a gastro-gastric intussusception and concurrent mineral-like gastric foreign bodies. After reduction of the intussusception, bilateral incisional gastropexy was performed to prevent recurrence. True gastrogastric intussusception is a rare condition and should be considered if the stomach has severe wall edema with a target sign on abdominal ultrasound. Computed tomography was useful to confirm this rare diagnosis and screen the entire abdomen for concurrent lesions. Key clinical message: This case highlights the usefulness of a CT examination to confirm this rare diagnosis, to determine the position of gastric compartments, and to detect potential concurrent lesions prior to surgery.

Caractéristiques échographiques et tomodensitométriques d'une véritable intussusception gastrogastrique avec corps étrangers concomitants chez un chien. Un chien Cane Corso mâle intact de 2 ans a été présenté pour faiblesse aiguë, vomissements et diarrhée. L'échographie abdominale a révélé que l'estomac présentait un ædème sévère de la paroi et une apparence de cible. La tomodensitométrie était compatible avec une intussusception gastro-gastrique et des corps étrangers gastriques de type minéral concomitants. Après réduction de l'intussusception, une gastropexie incisionnelle bilatérale a été réalisée pour prévenir les récidives. L'intussusception gastro-gastrique vraie est une affection rare et doit être envisagée si l'estomac présente un ædème sévère de la paroi avec un signe de cible à l'échographie abdominale. La tomodensitométrie a été utile pour confirmer ce diagnostic rare et d'examiner tout l'abdomen à la recherche de lésions concomitantes.Message clinique clé :Ce cas met en évidence l'utilité d'un examen CT pour confirmer ce diagnostic rare, pour déterminer la position des compartiments gastriques et pour détecter d'éventuelles lésions concomitantes avant la chirurgie.(Traduit par Dr Serge Messier).

Gastroesophageal intussusception secondary to induction of emesis with subsequent development of septic pericardial effusion after corrective surgery.

A juvenile boxer dog was diagnosed with gastroesophageal intussusception that occurred after the induction of emesis with apomorphine. A ventral midline coeliotomy and diaphragmotomy were performed and the intussusception was manually reduced. Despite initial satisfactory recovery, the dog was diagnosed with cardiac tamponade 1 week post-operatively. Escherichia coli was cultured from pericardial and pleural effusion samples. During subtotal pericardiectomy surgery the pericardium was found to be markedly thickened with adhesions to the epicardium, thoracic wall and diaphragm. Substantial haemorrhage and refractory hypotension necessitated the administration of a blood transfusion during surgery. The dog entered cardiac arrest in the immediate post-operative period and cardiopulmonary resuscitation was unfortunately unsuccessful. Gastroesophageal intussusception should be considered a possible severe adverse effect of administering apomorhine to induce emesis in dogs. Additionally, septic pericardial and pleural effusions may occur post-reduction of gastroesophageal intussusception.

Intussusception caused by intestinal neoplasia in mature rainbow trout (Oncorhynchus mykiss, Walbaum 1792).

The aquaculture industry is growing and includes the farming and breeding of more than 580 aquatic species worldwide. The rainbow trout (Oncorhynchus mykiss, Walbaum 1792) is the most commonly bred trout species in Hungary. As broodfish form the basis of most fish farms, investigation into tumours occurring in trout, although under-researched, has proven to be a valuable and necessary field of study. During our investigation, we examined a broodstock of 3- to 6-year-old rainbow trouts (800) affected with idiopathic intestinal tumours (3%) which had consequentially led to ileus (40%). While performing necropsy, initial pathological observations showed intussusceptions. Tumours were discovered upon opening the body cavity, as well as metastasis forming in the livers and in the vessels of the gills. Histopathological and immunohistochemical tests allowed us to identify the neoplasms. The primary adenocarcinoma was found to have been developed within the intestines of the fish. The tumour tissue broke through the basal membrane and infiltrated the propria, protruding asymmetrically into the lumen of the mid-intestines, causing it to narrow significantly. This subsequently led to passage disorders, invagination of the intestinal segment and finally the emaciation of the fish. Histopathological and immunohistochemical inspection of the tumour cells displayed a high mitotic index, confirming malignancy.

Two-portal video-assisted colopexy in the treatment of intussusception and prolapse of the descending colon in a lamb.

A lamb presented with recurrent prolapse of the descending colon. On clinical examination, intussusception of the descending colon with the prolapse of a segment was verified. The external anal sphincter had a rupture, extending to the lacerated wound in the anus. The lamb underwent colopexy with the two-portal video-assisted incisional technique and was discharged 6 days after the surgical procedure with a satisfactory clinical outcome. There were no recurrences or complications for at least 9 months. Video-assisted colopexy is an alternative treatment for intussusception and recurrent colon prolapse in sheep, even in the presence of an external anal sphincter rupture.

Clinical findings and outcomes of 153 dogs surgically treated for intestinal intussusceptions.

OBJECTIVE: To describe perioperative characteristics and outcomes of dogs surgically treated for intestinal intussusception. STUDY DESIGN: Multi-institutional, retrospective study. ANIMALS: One hundred fifty-three client-owned dogs with intestinal intussusception. METHODS: Dogs were included when they had undergone surgical treatment of a confirmed intestinal intussusception. Medical records were reviewed for demographics and clinical data, including surgical complications (graded 1-4). Follow-up was obtained via telephone interview with owners and referring veterinarians. RESULTS: Dogs had a median age of 10 months (range, 2-156), and the most common location for intussusception was ileocolic (66/153 [43%]). Most cases had no identifiable cause (104/155 [67%]). Intestinal resection and anastomosis (IRA) was performed in 129 of 153 (84%) dogs; enteroplication was performed in 28 of 153 (18%) dogs, including 13 with and 15 without IRA. Intraoperative complications occurred in 10 of 153 (7%) dogs, all involving intestinal damage during attempted manual reduction. The median duration of follow-up after discharge was 334 days (interquartile range, 15-990; range, 1-3302). Postoperative complications occurred in 53 of 153 (35%) dogs, including 22 of 153 (14%) with severe (grade 3 or 4) events. Diarrhea, regurgitation, and septic peritonitis were the most common postoperative complications; intussusception recurred in four of 153 (3%) dogs, all within 72 hours postoperatively. Fourteen-day postoperative mortality rate was 6%. CONCLUSION: Surgical treatment of intestinal intussusception was curative in most dogs, even when an underlying cause was not identified. Surgical complications were common, including a 14% risk of life-threatening short-term complications. CLINICAL SIGNIFICANCE: Surgical treatment of intestinal intussusception offers an excellent prognosis, but the potential life-threatening complications should be considered.

Uterine intussusception in immediate postpartum in bitches: case report / Intussuscepção uterina no puerpério imediato em cadelas: relato de caso

Uterine intussusception is a rare condition in bitches. This study aimed to report an unusual case of prolapsed uterine intussusception in a female dog. A 2-year-old American Bully bitch was received with labor history of large fetus requiring manual traction. The animal presented mucosal prolapse through the vulva, unproductive contractions and abdominal discomfort. After partial correction of mucosal prolapse, the dog was referred to ovary-hysterectomy surgery to correct prolapsed mucosa. During the surgical procedure, surgeons observed that the uterine horns were invaginated into the uterine body, rotated, and the tissue was slightly devitalized and congested. As previously described, this condition occurred during the immediate postpartum period. Thus, we suggest that this period can be a facilitator for the establishment of uterine intussusception.(AU)

A intussuscepção uterina é uma condição rara em cadelas. Portanto, este estudo tem por objetivo relatar um caso incomum de intussuscepção uterina prolapsada em fêmea canina. Uma cadela American Bully de dois anos de idade com histórico de parto de feto absoluto grande no qual necessitou de auxílio por tração manual foi apresentada. O animal exibiu um prolapso de mucosa através da vulva, contrações improdutivas e dores abdominais. Após a retração parcial do prolapso de mucosa, a cadela foi encaminhada para a ovário-histerectomia que teve por objetivo, também, corrigir a mucosa prolapsada. Durante o procedimento cirúrgico, foram verificados os cornos uterinos invaginados no corpo uterino, rotacionados, com o tecido levemente desvitalizado e congesto. Assim, como poucos casos encontrados na literatura, esta condição ocorreu durante o puerpério imediato. Dessa forma, sugere-se que este período, embora não seja um fator determinante para o estabelecimento da intussuscepção uterina, pode ser um facilitador no estabelecimento dessa condição.(AU)

Intussuscepção uterina em uma cadela sem raça definida - relato de caso / Uterine intussusception in a crossbred female dog - case report

O presente relato descreve uma condição rara de intussuscepção uterina em uma cadela sem raça definida, quatro anos de idade, diagnosticada por meio de celiotomia exploratória e análise anatomopatológica. Foi realizada ovariossalpingo-histerectomia (OSH) como tratamento. Essa patologia geralmente requer manejo cirúrgico porque o diagnóstico inicial pode ser desafiador.(AU)

The present study describes a rare condition of uterine intussusception in a 4 year old crossbred female dog diagnosed by exploratory celiotomy and anatomopathological analysis. As treatment, a ovariohysterectomy (OH) was performed. This pathology usually requires surgical management because the initial diagnosis can be challenging.(AU)

Dual-phase computed tomography angiography of intestinal carcinoid tumor as a lead point for cecocolic intussusception in a dog.

In an 8-year-old Labrador Retriever with progressive anorexia, constipation, and depression, CT revealed intussusception of the cecum into the ascending colon and a small cecal mass showing strong enhancement on arterial phase. The ileocecocolic junction was surgically resected and histologically diagnosed as cecocolic intussusception with carcinoid tumor. The carcinoid tumor worked as a lead point of intussusception in this case. Dual phasic CT is useful to assess the presence of gastrointestinal tumors as lead points in old dogs with intussusception.

[Intramural jejunal lipoma in the small intestine of a young Arabian horse causing invagination of the jejunum]. / Intramurales Lipom im Jejunum als Ursache für eine Invagination bei einer jungen Araberstute.

A 2-year-old Arabian horse was presented with severe colic symptoms. During explorative laparotomy, a jejuno-jejunal invagination secondary to a submucosal intestinal mass was detected. The involved jejunal segment was surgically removed and an end-to-end anastomosis was created. Opening the specimen demonstrated the presence of a nodular mass on the head of the intussusceptum, measuring 10 cm in diameter, and almost completely obliterating the intestinal lumen. Additionally, a severe hyperemia of the jejunal mucosa was visible. Histological examination, which revealed a well-demarcated mass in the submucosa of the jejunum consisting of well-differentiated adipocytes, led to the diagnosis of an intramural lipoma. The small intestinal mucosa displayed mild to moderate signs of congestion. Pedunculated lipomas in the mesentery of horses causing intestinal volvulus and obstruction are a frequent cause of small-intestine strangulation in aged horses. To the authors' knowledge, intramural intestinal lipomas to date have not been described in the horse. The mare recovered without complications and was free of colic symptoms after 6 months.

Enteroplication in cats with intussusception: a retrospective study (2001-2016).

OBJECTIVES: The aim of this study was to report complications, as well as short- and long-term clinical outcomes of cats suffering from surgically reduced intussusception with and without enteroplication. METHODS: Medical records of cats presented at our institution with intussusception between 2001 and 2016 were reviewed. The following data were retrieved: signalment; history; physical examination; diagnostic imaging, surgical and histological findings; and outcomes. Animals were grouped as with or without enteroplication. Duration of surgery, survival, complication and recurrence rates, duration of hospitalisation, and short- and long-term outcomes were compared. RESULTS: Cats with intussusception presented with unspecific type and duration of clinical signs. Male or male castrated cats and Maine Coons were over-represented in both groups. Enteroplication was performed in 48% (10/21) of the cats. Cats in the enteroplication group were significantly younger than those in the non-enteroplication group ( P = 0.023). Duration of surgery, time of hospitalisation, complication rate and outcomes did not differ between the two groups. Two complications in the short term and one complication in the long term were possibly associated with enteroplication. A recurrence of intussusception was seen in 2/17 cats approximately 12 months after initial surgery, both previously treated with enteroplication. CONCLUSIONS AND RELEVANCE: Although the number of cases was limited, our results suggest that enteroplication should be cautiously performed in cats with intussusception as it may be associated with major complications in the short and long term, and its efficacy remains unclear. Based on this study, the need for enteroplication in cats following a correction of intussusception could be questioned.

Management of a tracheal intussusception in a dog.

A 5-year-old Belgian Malinois dog was presented for evaluation of dyspnea of 1-month duration. Tracheal intussusception was diagnosed by tracheoscopy. Treatment consisted of surgical resection of the invaginated tracheal ring and the immediate cranial and caudal tracheal rings. The dog recovered uneventfully; complications included temporary emphysema after surgery. Seven months after surgery, the dog was still clinically normal. To the authors' knowledge, this is the first report of a tracheal intussusception treated surgically in a dog.

Gestion d'une intussusception trachéale chez un chien. Un chien Malinois âgé de 5 ans a été présenté pour l'évaluation d'une dyspnée d'une durée de 1 mois. L'intussusception trachéale a été diagnostiquée par trachéoscopie. Le traitement instauré consistait en la résection chirurgicale de l'anneau trachéal et des anneaux trachéaux crâniaux et caudaux immédiats. Le chien s'est rétabli sans incident; les complications ont inclus un emphysème temporaire après la chirurgie. Sept mois après la chirurgie, le chien était toujours cliniquement normal. À la connaissance des auteurs, il s'agit du premier rapport d'une intussusception trachéale traitée par chirurgie chez un chien.(Traduit par Isabelle Vallières).

Intestinal intussusception secondary to enteritis caused by Pythium insidiosum in a bitch: case report / Intussuscepção intestinal secundária à enterite causada por Pythium insidiosum em uma cadela: relato de caso

We report a case of intestinal intussusception secondary to enteritis caused by Pythium insidiosum infection in a 1-year-old mixed breed bitch that died after a 30-day history of bloody diarrhea, anorexia, weight loss, listlessness, dehydration, and pale mucous membranes. Necropsy revealed two areas of intussusception, one jejunum-jejunal and one ileum-cecum-colic. The first intussusception showed slight congestion of the intestinal loop, which was resolved by manual traction, while the second intussusception exhibited thickening, irregular yellow spots, and transmural congestion. Histologically, the jejunum-jejunal segment had ischemic lesions secondary and ileum-cecum-colic intussusception there was also necrotizing, pyogranulomatous enteritis associated with negative images of intralesional fungal hyphae that were well visualized by silver impregnation. Immunohistochemistry identified the hyphae as Pythium insidiosum. The diagnosis was made based on the histological changes and confirmed by immunohistochemistry. We can conclude that enteritis by P. insidiosum in dogs can occasionally cause intestinal intussusception and result in acute death.(AU)

Relata-se um caso de intussuscepção intestinal secundária à enterite causada por Pythium insidiosusm em uma cadela, sem raça definida, com um ano de idade, que morreu após apresentar 30 dias de diarreia sanguinolenta, anorexia, perda de peso, apatia, desidratação e mucosas pálidas. Na necropsia verificaram-se duas áreas de intussuscepções, sendo uma jejuno-jejunal e outra íleo-ceco-cólica. Na primeira havia discreta congestão, que foi desfeita pela tração manual, e na segunda observou-se espessamento segmentar, focos amarelados irregulares e congestão transmural do intestino. Microscopicamente, no segmento jejuno-jejunal observaram-se moderadas lesões isquêmicas secundárias à intussuscepção, e no segmento íleo-ceco-cólica verificou-se enterite piogranulomatosa e necrosante, segmentar, associada a imagens negativas de hifas intralesionais, impregnadas pela prata. Pela imuno-histoquímica, as hifas foram imunomarcadas para Pythium insidiosum. O diagnóstico foi realizado com base nas características microscópicas das lesões e morfotintoriais das hifas e foi confirmado pela imuno-histoquímica. De acordo com esses dados, é possível concluir que a infecção intestinal por P. insidiosum em cães pode causar intussuscepção e morte.(AU)

Ileocolic junction resection in dogs and cats: 18 cases.

There is limited veterinary literature about dogs or cats with ileocolic junction resection and its long-term follow-up. To evaluate the long-term outcome in a cohort of dogs and cats that underwent resection of the ileocolic junction without extensive (≥50%) small or large bowel resection. Medical records of dogs and cats that had the ileocolic junction resected were reviewed. Follow-up information was obtained either by telephone interview or e-mail correspondence with the referring veterinary surgeons. Nine dogs and nine cats were included. The most common cause of ileocolic junction resection was intussusception in dogs (5/9) and neoplasia in cats (6/9). Two dogs with ileocolic junction lymphoma died postoperatively. Only 2 of 15 animals, for which long-term follow-up information was available, had soft stools. However, three dogs with suspected chronic enteropathy required long-term treatment with hypoallergenic diets alone or in combination with medical treatment to avoid the development of diarrhoea. Four of 6 cats with ileocolic junction neoplasia were euthanised as a consequence of progressive disease. Dogs and cats undergoing ileocolic junction resection and surviving the perioperative period may have a good long-term outcome with mild or absent clinical signs but long-term medical management may be required.

Jejunojejunal intussusception in foal: case report / Intussuscepção jejunojejunal em potro: relato de caso

Intussusceptions are unusual intestinal incidents which may result in acute and progressive or recurrent abdominal discomfort in foals. This condition asymptomatically affects newborn foals (3-12 months), are surgical emergencies when it involves the small intestine, especially the jejunum. Transabdominal ultrasound evaluation is an important diagnostic method, due to their size limitations for acute abdomen evaluation. The present report shows the importance of using transabdominal ultrasound in foals with acute abdomen.(AU)

As intussuscepções são acidentes intestinais incomuns e que podem resultar em desconforto abdominal agudo e progressivo ou recorrente em potros. Esta condição afeta potros neonatos de forma assintomática e de 3 a 12 meses são emergências cirúrgicas quando envolvem o intestino delgado, principalmente o jejuno. A avaliação ultrassonográfica transabdominal é um importante para o exame desses animais devido às limitações de seu tamanho para avaliações do abdômen agudo. O presente relato de caso mostra a importância da utilização do ultrassom transabdominal em potros com abdômen agudo.(AU)
