ABSTRACT

Background: Gastrointestinal dysfunction in reptiles is a common condition seen in animal medicine, and is often causedby inappropriate husbandry. The purpose of this report is to describe the case of a surgical procedure for enterectomy ofthe small intestines, performed as treatment for an intussusception with cloacal protrusion that occurred in a red-earedslider (Trachemys scripta elegans) kept as a pet.Case: A 20-year-old red-eared slider (Trachemys scripta elegans) was taken into medical care after the owners observationof a cloacal protrusion that had started 72 h previously. During physical examination the protrusion was noted as an intestinalsegment of approximately 5 cm, which was not reducible. Complementary examinations, including radiography and hematological profiling, were performed and revealed no significant findings; therefore, it was decided that an exploratory celiotomywould be conducted. The patient was referred to the surgical unit for the procedure and underwent surgical anesthesia. Afterappropriate antisepsis of the surgical area, a plastron osteotomy was performed using a previously sterilized oscillatory saw ata 45º angulation. The celomatic membrane was subsequently incised to enable both cavity and intestinal inspection allowingobservation of the intussusception in the small intestine of the animal with the intussuscept segment protruding through thecloaca. The intussusception was undone, and an enterectomy was performed to remove the unviable intestine, using intestinalresection and subsequent anastomosis with simple interrupted sutures using 4-0 nylon, followed by intestinal reposition in thecavity. The celomatic membrane was closed using continuous suture with 4-0 nylon. The plastron fragment was then repositioned with the aid of eight...(AU)

ABSTRACT

Background: Gastroesophageal intussusception is characterized by the invagination of the stomach into the esophagus,with or without the involvementof adjacent organs such as the spleen, pancreas, and omentum. In dogs, this condition hasno breed or sex predisposition. As it is an infrequent disease in routine veterinary medical practice, this study reports acase of gastroesophageal intussusception in a dog necropsied at the Veterinary Hospital of the Federal Rural Universityof Pernambuco (HOVET - UFRPE), Recife, Brazil.Case: The body of a 12-year-old black mixed breed male dog was sent to the Pathology Department (Necropsy Sectorof the Federal Rural University of Pernambuco - UFRPE) for a necropsy. The animal had a previous 4-year history ofrecurrent emesis and limb weakness, primarily in the anterior limbs, that worsened in the previous months and progressedto death. No previous treatments were reported by the owner. On external examination, the animal had a low body score(cachectic), forelimb joints with great flexibility, congested oral and ocular mucous membranes, enophthalmos, and increased volume in the perianal region. At the opening of the thoracic cavity, the final third of the esophagus was dilatedand gastroesophageal intussusception, edema, and pulmonary congestion were noted. In the abdominal cavity, there washepatic and renal congestion and large intestine and rectal ampoule dilation, with a large amount of solid and retainedfeces (fecaloma), perianal hernia, and testicular neoformation. These findings were consistent with those observed in deathcaused by cardiorespiratory failure secondary to gastroesophageal intussusception.Discussion: The pathophysiology of gastroesophageal intussusception is still not elucidated and is probably multifactorial.This condition causes reverse gastric peristalsis associated with a sudden and sustained increase in abdominal...(AU)

ABSTRACT

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.

ABSTRACT

Background: Intussusception, characterized by invagination of an intestinal segment into the lumen of the adjacent segment, is one of the main causes of intestinal obstruction in cattle, and occurs more frequently in calves. The diagnosis of the disease is based on the history, clinical examination, and complementary exams, which are a challenge in this species, especially in calves, in which transrectal palpation is limited. As it is a non-invasive, effective, and low-cost test, ultrasonography could be an important tool in the diagnosis of intestinal obstructions, in which time is essential for the prognosis. Therefore, the objective was to report a case of intussusception in a calf diagnosed by ultrasound. Case: A 4-month-old calf, weaned at 3 months and raised intensively, was treated at the Clínica de Bovinos de Garanhuns, campus of the Universidade Federal Rural de Pernambuco (CBG/UFRPE), with a history of apathy, anorexia, and dyschezia for 3 days. On physical examination, fever, moderate dehydration, tachycardia, tachypnea with polypnea, bilaterally bulging abdomen, sound of fluid on ballottement, ruminal and intestinal hypomotility, and melena were observed. The hematological findings revealed leukocytosis due to neutrophilia (degenerate neutrophils), hypoproteinemia, and hyperfibrinogenemia. The analysis of the ruminal fluid showed compromised microbiota and increased chloride content. The transabdominal ultrasonography demonstrated, in the right ventral region, hypermotile and full small bowel loops and an increase in the volume of the peritoneal fluid. In addition, there was a segment of the small intestine which, in cross-section, showed multiple concentric rings ("onion rings", "target pattern", or "bull's eye") and adherence to adjacent loops, compatible with intestinal obstruction due to intussusception. Due to the seriousness of the clinical condition and the ultrasound findings, the animal was euthanized and the necropsy revealed focal fibrinous peritonitis and intestinal obstruction due to intussusception in ileum intestinal segments. Discussion: Intussusception has previously been reported in calves, however this is the first report of ultrasound diagnosis of the disease in Brazil. Although the etiology is rarely confirmed, the age group and recent changes in diet (weaning) were predisposing factors. The history, clinical signs, and laboratory tests were similar to those described in cattle with intussusception, however they may be present in other gastrointestinal illnesses. Other authors have also reported that the nonspecificity of the signs and the impossibility of performing transrectal palpation made it difficult to diagnose intestinal obstruction in calves without the use of other diagnostic tools. As it is a non-invasive and accurate technique, ultrasound has been used in ruminants for diagnostic purposes, including intestinal obstructions. In the present case, the main findings are described as the presence of a lesion with the appearance of multiple concentric rings, hypermotile, dilated, and full intestinal loops. The pathological findings were compatible with the ultrasound images and similar to those described by other authors, confirming the diagnosis. The use of ultrasonography as a diagnostic tool in cattle should be expanded, aiming at the early determination of diagnosis and prognosis, to reduce producer costs and animal discomfort. In cases of intussusception, late diagnosis makes treatment unfeasible.

ABSTRACT

Intussusception is the invagination of one segment of the intestine into the part of the tract that either precedes or follows in the gastrointestinal tract of different species of animals. This report describes a case of fatal multiple intestinal intussusceptions and torsion associated with non-degradable foreign body gastrointestinal obstruction in a captive lion (Panthera leo) in a zoo in Nigeria. Parenchymatous tissues were aseptically collected during necropsy for bacteriological isolation and histopathology. Also, intestinal fecal material was collected and sent for parasitological examination. The main lesions were gastroduodenal, duodeduodenal, duodejejunal and jejunojenunal intussusceptions and duodenal torsion. A non-degradable towel-like fabric foreign body obstruction along the pyloric antrum/canal region of the stomach down to the jejunum was found. Microscopic lesion included ischemic necrosis of inner circular and outer longitudinal smooth muscles of the intestine with necrosis of other layers and vascular congestion. Parasitological examination revealed presence of Babesia spp. in blood smear examined before the death of the lion. While Escherichia coli was isolated from the liver on MacConkey agar. A diagnosis of intussusception and torsion associated with non-degradable foreign body (fabric) gastrointestinal obstruction was made. This first case of ingestion of a non-degradable fabric foreign body leading to gastrointestinal obstruction in captive lion in Nigeria has brought about the need for vigilance of zoo authority to prevent a recurrence during crowd influx to the garden.(AU)

ABSTRACT

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.

ABSTRACT

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)

ABSTRACT

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.

ABSTRACT

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)

ABSTRACT

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)

ABSTRACT

Background: Due to the numerous complications that enteropexy may cause in domestic animals and humans, this study aimed at investigating the microscopic level, the damage generated by this technique in mice, in order to investigate the morphometric changes caused by enteropexy technique in rats. Materials, Methods & Results: Eighteen Wistar rats were submitted to surgical technique of enteropexy. To evaluate intestinal disorders they were euthanized at 30 (Group I), 60 (group II) and 90 (group III) days after the procedure. The animals were perfused with 2.5% glutaraldehyde and 4% paraformaldehyde for the removal of intestinal fragments for analysis in conventional microscopy and scanning electron microscopy. In classical histopathology, group I presented mild lesions with necrosis of the epithelium and infiltration of mononuclear cells. After 60 days, extensive ischemic necrosis area was observed, characterized by the denudation of epithelium cells and cellular debris in the lumen surface and loss of intestinal crypts. After 90 days (group III) lesions were evident and were characterized by strong coagulative necrosis of epithelial cells and intestinal crypts. Under electron microscopy, group I showed early fusion of the adjacent intestinal walls. After 60 days there was adherence of luminal stenosis and intestinal walls. In group III loss of epithelium and substitution [...]
