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.

Gastroesophageal intussusception in a 4-week-old German shepherd puppy.

The surgical treatment of a gastroesophageal intussusception (GEI) in a 4-week-old male intact German shepherd puppy is described in this report. Bilateral gastropexies were performed; an incisional gastropexy on the right and a gastrostomy tube gastropexy on the left. The dog recovered well and is thriving long-term with no clinical signs of persistent megaesophagus. With the combination of early detection and surgical correction of GEI, mortality rates may be lower than the 95% mortality rate that has been reported in previous literature and supports new studies that have reported a 65% survival rate long-term. Key clinical message: Young animals presenting with vague clinical signs require thorough evaluation to identify uncommon, yet life-threatening diseases such as GEI. Early detection and interventions can subsequently lead to successful outcomes.

Intussusception gastro-oesophagienne chez un chiot berger allemand de 4 semaines. Le traitement chirurgical d'une intussusception gastro-oesophagienne (GEI) chez un chiot berger allemand mâle intact âgé de 4 semaines est décrit dans ce rapport. Des gastropexies bilatérales ont été réalisées; une gastropexie incisionnelle à droite et une gastropexie par tube de gastrostomie à gauche.Le chien a bien récupéré et se porte bien à long terme sans aucun signe clinique de mégaoesophage persistant.Avec la combinaison de la détection précoce et de la correction chirurgicale de la GEI, les taux de mortalité peuvent être inférieurs au taux de mortalité de 95 % qui a été rapporté dans la littérature antérieure et soutient de nouvelles études qui ont rapporté un taux de survie à long terme de 65 %.Message clinique clé :Les jeunes animaux présentant des signes cliniques vagues nécessitent une évaluation approfondie pour identifier des maladies rares, mais potentiellement mortelles, telles que la GEI. Une détection et des interventions précoces peuvent ensuite conduire à des résultats positifs.(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).

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).

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.

Colocolic Intussusception Associated with Octangium sp. (Digenea: Microscaphidiidae) in a Green Sea Turtle Chelonia mydas.

Reports of intussusception in sea turtles are generally linked to marine debris ingestion; therefore, only a few cases of the disease are associated with parasitic infestations. The objective of this study was to describe the necropsy findings of the first reported case of colocolic intussusception in a green sea turtle Chelonia mydas, associated with the helminth Octangium sp. A juvenile female green sea turtle, which was registered and rescued by the team from the Cetaceans Project of Costa Branca, State University of Rio Grande do Norte, was examined. The animal died 1 d after being treated and was immediately submitted for necropsy. Our findings indicated that parasitic infestation by Octangium sp. in the green sea turtle caused intussusception and consequently led to the animal's death. Early diagnosis and surgical correction are fundamental for a good prognosis and, consequently, for successful rehabilitation of marine species.

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.

Imaging and clinical features of a true gastrogastric intussusception in a dog.

An 18-month-old male mixed breed dog was evaluated for acute vomiting and hematemesis. Clinical signs and initial radiographic findings shared commonalities with reported cases of pylorogastric intussusception in dogs. However, unlike previously reported cases, additional imaging [including ultrasound and computed tomography (CT)] revealed invagination of the gastric fundus into the gastric body, consistent with true gastrogastric intussusception. These findings were confirmed with histopathology and on necropsy. Key clinical message: Although extremely rare, gastrogastric intussusception should be included as a differential diagnosis for any patient presenting with acute vomiting, abdominal pain, dehydration, or tachycardia in combination with the diagnostic imaging findings described in this report.

Caractéristiques cliniques et d'imagerie d'une intussusception gastro-gastrique vraie chez un chien. Un chien mâle de race croisée âgé de 18 mois fut évalué pour des vomissements aigus et de l'hématémèse. Les signes cliniques et les trouvailles radiographiques initiales partageaient des similarités avec des cas rapportés d'intussusception pyloro-gastrique chez des chiens. Toutefois, contrairement aux cas rapportés précédemment, des examens d'imagerie supplémentaires [incluant l'échographie et la tomodensitométrie (CT)] ont révélé une invagination du fundus gastrique dans le corps de l'estomac, compatible avec une intussusception gastro-gastrique vraie. Ces données furent confirmées lors de l'examen histopathologique et de la nécropsie.Message clinique clé :Bien qu'extrêmement rare, l'intussusception gastro-gastrique devrait être incluse dans le diagnostic différentiel pour tout patient présenté avec des vomissements aigus, de la douleur abdominale, de la déshydratation ou de la tachycardie en combinaison avec les trouvailles en imagerie diagnostique décrites dans le présent rapport.(Traduit par Dr Serge Messier).

Successful surgical resolution of a ceco-cecal intussusception in a 15-month-old Angus heifer.

A 15-month-old Angus heifer was presented for anorexia and abdominal discomfort. Transabdominal ultrasound was suggestive of a ceco-cecal intussusception. Exploratory laparotomy confirmed the diagnosis and a cecectomy was performed. The heifer recovered well and continued to gain weight after discharge. This is the first report of a heifer with ceco-cecal intussusception in North America.

Correction chirurgicale réussie d'une intussusception caeco-cæcale chez une génisse de race Angus âgée de 15 mois. Une génisse de race Angus âgée de 15 mois est présentée pour une anorexie et des signes d'inconfort abdominal. Une échographie transabdominale révèle la présence d'une intussusception caeco-caecale. Le diagnostic est confirmé par laparotomie exploratrice et une typhlectomie est réalisée. La génisse a bien récupéré après l'opération et a continué à prendre du poids après sa sortie de l'hôpital. Ceci est le premier rapport de cas d'une génisse atteinte d'une intussusception caeco-caecale en Amérique du Nord.(Traduit par Dr Thibaud Kuca).

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.

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).

[Ceco-cecal intussusception in a Simmental heifer]. / Caeco-caecale Invagination bei einem Simmentaler Rind.

This report describes the clinical, laboratory and ultrasonographic findings in a Simmental heifer with a ceco-cecal intussusception. The general condition of the heifer was moderately reduced and it showed mild colic signs. Physical examination revealed a firm longish mass visible and palpable in the right flank. Findings upon rectal examination, fecal output und defecation were normal. Ultrasound examination of the mass revealed features typical for an intussusception. Based on the slow development of symptoms, normal fecal output and ultrasonography findings, a ceco-cecal intussusception was diagnosed. Right flank laparatomy was performed under general anaesthesia, and an end-to-side anastomosis between the jejunum and the spiral colon was made after resection of the intussuscepted intestines. Recovery was uneventful.

Ileo-ceco-rectal Intussusception Requiring Intestinal Resection and Anastomosis in a Tawny Eagle (Aquila rapax).

A 23-year-old male tawny eagle (Aquila rapax) was examined because of sudden onset of lethargy, regurgitation, and hematochezia. An intestinal obstruction was suspected based on radiographic findings, and an ileo-ceco-rectal intussusception was confirmed by coelioscopy. A 14.3-cm section of intestine was resected before an intestinal anastomosis was done. Coelomic endoscopic examination confirmed a postsurgical complication of adhesions between the intestinal anastomosis and the dorsal coelomic wall, resulting in a partial luminal stricture and requiring surgical removal of the adhesions. Rectoscopy was useful in diagnosing a mild luminal stricture related to the second surgery. Complete recovery was observed 2 months after surgery. Lack of further complications in the 2 years after surgery demonstrates good tolerance of intestinal resection and anastomosis of a large segment of bowel in an eagle. This report is the first reported case of intussusception in an eagle and emphasizes the potential use of endoscopic examination in the diagnosis as well as in the management of complications.

Acute gastroesophageal intussusception in a juvenile Australian Shepherd dog: endoscopic treatment and long-term follow-up.

BACKGROUND: Canine gastroesophageal intussusception (GEI) is a rare and potentially fatal disease usually affecting puppies or young dogs < 3 months of age and of medium to large breeds. Surgical intervention has been advocated as the therapy of choice by most authors. Endoscopic treatment may offer an advantageous or alternative method of treatment. CASE PRESENTATION: GEI was diagnosed in a nine-week-old Australian Shepherd dog with an acute onset of vomiting and regurgitation and compatible radiographic findings on thoracic radiography. Treatment consisted of endoscopic gastric repositioning and placement of a percutaneous endoscopic gastrostomy (PEG) tube to prevent repeated dislocation of the stomach, and to allow for nutritional supplementation During a follow-up period of eight months, thoracic radiographs were obtained showing persistent esophageal dilatation in the absence of compatible clinical signs. CONCLUSION: Endoscopic intervention is an effective, alternative in selected canine GEI- cases, allowing for rapid, minimally invasive confirmation of diagnosis and therapy. After initial treatment, radiographic long-term follow-up seems prudent even in asymptomatic patients.

[Endoscopic reposition of pylorogastric intussusception in a dog]. / Endoskopische Reposition einer pylorogastrischen Invagination beim Hund.

A 7 month old West Highland White Terrier was presented with anorexia and vomitus since 4 days. On physical examination the dog was depressed, febrile and showed abdominal pain. During abdominal ultrasonographic examination a pylorogastric intussusception was suspected and this was confirmed subsequently by gastroscopy. The invaginated pylorus could be repositioned without complications using the endoscope. The dog recovered completely and without recurrence. A pylorogastric intussusception is a rarely diagnosed cause of an acute abdomen that can be resolved with a minimal invasive procedure.

Gastrointestinal torsions and intussusception in northern koalas (Phascolarctos cinereus) at San Diego Zoo (1976-2012).

The recent classification as threatened status of the northern koala (Phascolarctos cinereus) by the Australian Government highlights the importance of the conservation and health management of this iconic Australian marsupial. This case series describes gastrointestinal torsion and intussusception in six northern koalas (three males, three females, 2-11 yr old) at the San Diego Zoo from 1976 to 2012. Two koalas died shortly after presentation. Diagnoses of ileocecal intussusception, resulting from enteritis in one case and cecal torsion in the other, were made at postmortem examination. One koala died 4 days after an exploratory laparotomy, with negative findings, and an acute double colonic intussusception was diagnosed at postmortem examination. Two small intestinal mesenteric torsion and one proximal colon mesenteric torsion cases were successfully corrected surgically. In the case of colonic mesenteric torsion, the koala had recurrent clinical signs 2 wk later, and a second surgery requiring resection and anastomosis of ischemic jejunum was performed, with the koala dying shortly afterward. One koala with small intestinal torsion had a recurrence of torsion 22 mo later and subsequently died. The koala with the second case of small intestinal torsion remains alive 14 mo postsurgical correction. All six koalas presented with signs of colic that included anorexia, lethargy, depression, acute abdominal distension, abdominal stretching, decreased fecal output, open-mouth gasping, or a combination of symptoms. Abdominal radiographs may show stacked gastrointestinal linear gas patterns and contrast stasis. Prevalence of torsion and intussusception is low at this institution (2%), although recurrence in individuals is common (50%) and overall survival is poor (83%), which emphasizes the importance of timely recognition, surgical correction, and postoperative management. While inciting etiologies were unable to be determined in these cases, monitoring generalized gastrointestinal health and differing Eucalyptus sp. effects on individual koala's gastrointestinal function, parasite control, and stress minimization through standardized husbandry practices are likely important.

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.

Duodenogastric intussusception with concurrent gastric foreign body in a dog: a case report and literature review.

A 3 yr old spayed female boxer weighing 22.8 kg was presented for severe, acute vomiting and tenesmus. Tachycardia, tachypnea, dehydration, and abdominal pain were present on physical examination. Abdominal radiographs showed a foreign object (golf ball) in the fundus of the stomach, and a larger, round, soft-tissue opacity mass in the region of the pylorus. Endoscopic removal of the foreign object was unsuccessful. A large soft-tissue mass (duodenogastric intussusception) was visualized with endoscopy, but was not correctly diagnosed until surgery. A midline exploratory celiotomy was performed and the duodenogastric intussusception was diagnosed and manually reduced. Severe pyloric wall edema and minimal bruising were present. A routine fundic gastrotomy was performed and the foreign object was removed. A right-sided incisional gastropexy and duodenopexy were performed in attempt to prevent recurrence of the intussusception. The dog was discharged from the hospital 38 hrs after surgery, and was normal on follow-up 1 yr after surgery. The dog in this report is the sixth documented case of duodenogastric/pylorogastric intussusception in the veterinary literature. This is the first reported case with a concurrent gastric foreign body and endoscopic visualization of the intussusception.

Ultrasonographic diagnosis and surgical management of double intestinal intussusception in 3 dogs.

The diagnosis and treatment of double intestinal intussusception in 3 pups with persistent vomiting, diarrhea, dehydration, anemia, leucocytosis, and electrolyte imbalance are described. Ultrasonography confirmed intussusception and laparotomy revealed double intussusceptions. Intussusceptions were corrected by manual reduction in 1 pup and intestinal resection and anastomosis in 2 pups. Two pups survived and 1 pup died on the 4th day after surgery.

Le diagnostic et le traitement d'une intussusception intestinale double chez 3 chiots avec des vomissements persistants, de la diarrhée, de la déshydratation, de l'anémie, de la leucocytose et un déséquilibre électrolytique sont décrits. L'échographie a confirmé l'intussusception et une laparatomie a révélé des intussusceptions doubles. Les intussusceptions ont été corrigées par une réduction manuelle chez 1 chiot et une résection intestinale et une anastomose chez 2 chiots. Deux chiots ont survécu et 1 chiot est mort le quatrième jour après la chirurgie.(Traduit par Isabelle Vallières).

Noninvasive hydrostatic reduction of an ileocecocolic intussusception in a puppy.

A 5-week-old male intact Golden Retriever puppy was presented for a history of vomiting and diarrhea with hematochezia. Ultrasound findings confirmed the presence of an ileocecocolic intussusception. Surgical correction was declined because of financial concerns. Based on a pediatric procedure used in humans, an ultrasound-guided hydrostatic reduction (USGHR) was performed. This procedure consisted in injecting saline rectally under controlled pressure to mechanically reduce the intussusception. Reduction of the intussusception and evaluation of potential complications were concurrently evaluated by ultrasound during the procedure. No recurrence was observed the next day and the puppy was discharged. Follow-up indicated that the dog was still doing well 6 months later. This case report describes a new technique in veterinary medicine allowing successful nonsurgical reduction of an ileocecocolic intussusception in a dog. This procedure is innovative, simple, and substantially decreases the cost and minimizes morbidity potentially associated with surgical management.
