Successful emergency surgery for accidental ingestion of multiple neodymium magnets in an Argentine tegu (Salvator merianae)

A large Argentine tegu (Salvator merianae) presented with anorexia. Initial radiographs revealed a metallic foreign body in the stomach. The tegu vomited and became inactive two days later. A follow-up radiograph revealed the persistence of the foreign body in the same region. The foreign body was identified as a cluster of multiple magnets resembling neodymium magnets reported missing by the owner. An emergent laparotomy was performed due to gastrointestinal perforations caused by the multiple magnets. The surgical intervention revealed perforations in the walls of the stomach and small intestine and progressing acute peritonitis. Three magnets were extracted from the abdominal cavity and the tegu showed recovery. At 200 days postoperatively, the tegu continued to demonstrate good appetite and energy levels.

Inadvertent removal of a needle foreign body via endoscopic suctioning in a dog

A 6-month-old intact female English bulldog was presented following witnessed ingestion of a sewing needle. The dog underwent attempted endoscopic retrieval under general anesthesia. The needle foreign body was visualized but could not be removed due to orientation, and subsequent attempts at visualization were unsuccessful. Due to the unsuccessful removal, radiographs were obtained before intended surgical exploration, and no sewing needle was identified. The needle was subsequently identified in the working channel of the endoscope, and the dog recovered uneventfully. This is the first report to describe inadvertent endoscopic suctioning of a sharp, needle foreign body. Key clinical message: Endoscopy is a key tool in the management and treatment of sharp gastric foreign bodies. Complications are uncommon and typically patient-focused, including gastric perforation or irritation. However, this case report identifies an additional complication that should be considered when endoscopy is not successful.

Clinical features and outcomes of dogs with attempted medical management for discrete gastrointestinal foreign material: 68 cases (2018-2023)

OBJECTIVE

To retrospectively describe clinical characteristics of canine gastrointestinal foreign bodies (GIFB) that were successfully and unsuccessfully managed conservatively.

ANIMALS

68 client-owned dogs presented to the Texas A&M Small Animal Teaching Hospital between January 1, 2018, and October 1, 2023, for GIFB where medical management was attempted.

CLINICAL PRESENTATION

Medical records were reviewed for signalment, history, physical examination, bloodwork, diagnostic imaging, foreign body type, location, treatments, and outcome. Success was defined as the passage of the foreign body through the colon, while failure was defined as requiring surgery, endoscopy, or euthanasia.

RESULTS

Medical management was successful in 32 cases (47%; 95% CI, 0.32 to 0.66). Gastric dilation resolved in all success cases (n = 5 [100%]; 95% CI, 0.32 to 2.3) but did not resolve in any failure cases (13 [0%]). Small intestinal dilation resolved in all success cases (n = 13 [100%]; 95% CI, 0.53 to 1.7) but progressed in most failure cases (9 [75%]; 95% CI, 0.34 to 1.4). In the success group, 31 GIFB were nonlinear (96.9%; 95% CI, 0.66 to 1.4), while 1 was linear (3.1%; 95% CI, 0.001 to 0.17). In the failure group, 29 GIFB were nonlinear (80.6%; 95% CI, 0.54 to 1.16), while 7 were linear (19.4%; 95% CI, 0.08 to 0.4). Of the cases that elected surgery (n = 29 [42.7%]; 95% CI, 0.29 to 0.61), resection and anastomosis was performed in 3 cases (10.3%; 95% CI, 0.02 to 0.3). All cases that required resection and anastomosis were nonlinear GIFB.

CLINICAL RELEVANCE

Conservative management of GIFB provides a feasible treatment option and may be considered based on presentation, foreign body location, hemodynamic stability of the patient, diagnostic imaging, and type of foreign body.

Video-Assisted Ventral Bulla Osteotomy to Remove a Bullet Foreign Body in a Cat

A 7 yr old castrated male domestic shorthair presented for assessment of a chronic left head tilt, losses of balance, and positional nystagmus. A computed tomographic scan of the head revealed several fragments of a metallic foreign body in the left tympanic cavity. The foreign material was removed under endoscopic assistance through a minimally invasive ventral bulla osteotomy. No complications were noted during the immediate postoperative period. Follow-up 5 mo after surgery revealed complete resolution of the neurological signs with no evidence of recurrence. Foreign bodies associated with middle ear infection have not been previously reported in the cat. They should now be included in the differential diagnosis of vestibular disease. Endoscopic-assisted foreign body removal in the middle ear seems to be a safe and efficient way to retrieve small foreign bodies in bullae in cats.

Duodenal ileus caused by a cage magnet in a Fleckvieh cow

The present report aims to describe the case of a duodenal obstruction ileus in a dairy cow that was caused by a cage magnet. The 4.7-year-old German Fleckvieh cow was hospitalized because of symptoms of intestinal obstruction such as anorexia, noticeable drop in milk yield, reduced defecation, dehydration and positive percussion and swinging auscultation in a circumscribed area cranial of the right flank over the last 2 ribs. Six months as well as 3 days prior to hospitalization the cow had already been treated for signs of hardware disease, which included administration of a cage magnet.After the initial clinical diagnostic procedure on hospital admission, a diagnostic laparotomy in the right paralumbar fossa was performed to identify the cause of the ileus. The cranial part of the duodenum was markedly dilated, and a solid foreign body was found obstructing the intestine immediately aboral to the duodenal sigmoid flexure. This was identified as a cage magnet, which was massaged in retrograde direction into the pyloric antrum and removed via abomasotomy. The cow recovered from surgical intervention and was discharged from the hospital 6 days later.The present report describes an unusual complication of cage magnet administration, which is a standard veterinary procedure and generally considered a safe treatment option in cows with clinical signs of acute traumatic reticuloperitonitis.

Penetrating wood foreign bodies (stob) of the coronary band in horses: 15 cases

OBJECTIVE

To retrospectively report the historical and clinical findings, diagnostics, treatment, and outcome of horses with penetrating wood foreign bodies (PWFBs) of the coronary band.

ANIMALS

15 client-owned horses.

CLINICAL PRESENTATION

Horses had varying degrees of lameness and soft tissue swelling of the coronary band and pastern region. A defect in the coronary band was identified, but the actual wood foreign body was not always readily visualized.

RESULTS

Medical records of horses diagnosed with PWFBs of the coronary band between 2004 and 2023 were reviewed. Information retrieved from the medical records included history, signalment, diagnostics, treatment, and outcome. Thirteen of 15 horses that sustained a PWFB to the coronary band were participating in foxhunting. Penetrating wood foreign bodies occurred more frequently near the central axis or toe region (11/15) and more commonly in the forelimbs (11/15). Removal of PWFBs can be performed with the horse standing and sedated with regional anesthesia. Complete removal of the PWFB required partial removal of the adjacent hoof wall.

CLINICAL RELEVANCE

Penetrating wood foreign bodies occurred in the coronary band and lodged distally in the hoof wall of horses. Foxhunting may be a risk factor for this type of injury. Penetrating wood foreign bodies occurred most commonly in the front feet, near the central axis of the coronary band. Complete removal of the PWFB required removing a section of the adjacent hoof wall. The prognosis for return to the previous level of activity following treatment was favorable.

Fragmented acupuncture needle as a linear metallic foreign body near the proximal interphalangeal joint of a horse

OBJECTIVE

To describe the clinical presentation, diagnosis, and treatment of a fragmented, migrating acupuncture needle near the palmar proximal interphalangeal joint (PIPJ) of a horse.

ANIMAL

A 9-year-old Warmblood cross mare.

CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES

The mare presented for evaluation of a linear metallic foreign body on the palmar lateral aspect of the PIPJ following acupuncture treatment. The mare had a pinpoint puncture wound and sensitivity to palpation over the lateral aspect of the PIPJ region. The referring veterinarian performed radiographs and found a linear metallic foreign body near the lateral palmar PIPJ. Ultrasonographic examination demonstrated a hyperechoic lesion consistent with a metallic object in the soft tissues of the palmar lateral aspect of the PIPJ.

TREATMENT AND OUTCOME

The horse was anesthetized, and the linear metallic foreign body was removed. The use of intraoperative ultrasound and digital radiographs assisted in determining the location of and surgical approach to remove the foreign body. The linear metallic foreign body was the fragmented segment (body) of an acupuncture needle. The mare recovered from surgery uneventfully and returned to the previous level of activity.

CLINICAL RELEVANCE

This report demonstrates the potential risks of prolonged retention and or delayed removal of acupuncture needles in the form of needle fragmentation and migration. It also demonstrates the use of imaging in determining the location and position of small, thin metallic foreign bodies to aid in surgical approach and removal.

Cardiac biomarkers as tools in the prediction and diagnosis of traumatic pericarditis and traumatic reticuloperitonitis in cattle and buffaloes

BACKGROUND

In the livestock industry, Foreign Body Syndrome is a devastating disease condition. Feeding management, lacking of food discrimination, and eating chopped food increase the risk of swallowing sharp foreign bodies in bovine species. In addition to the honeycomb cells shape of the reticulum, the contractions of the reticular wall, gravid uterine pressure, and parturition efforts, foreign bodies can penetrate the reticular wall, causing cascade of problems including traumatic reticulitis, traumatic reticuloperitonitis, and traumatic pericarditis. The present study was carried out to evaluate the diagnostic significance of cardiac troponin I rapid test cassette and other cardiac biomarkers including serum cardiac troponin I (cTn I), creatine kinase-myocardial band (CK-MB), lactate dehydrogenase (LDH), and aspartate aminotransferase enzyme (AST), in confirmed cases of traumatic pericarditis (TP) and/or traumatic reticuleoperitonitis (TRP) in cattle and buffaloes.

METHODS

A total number of 30 animals (22 cattle and 8 buffaloes) with different signs such as anorexia, jugular distension, brisket edema, and signs of pain (reluctance to move, arching back, and abduction of the forelimbs) were included in the present study. Based on case history, clinical signs, ferroscopic, pericardiocentesis, radiographic and ultrasonographic examinations, TP were confirmed in cattle (n = 10) and buffaloes (n = 8) while TRP were confirmed only in cattle (n = 12). Additionally, 20 clinically healthy animals (n = 10 cattle and 10 buffaloes) were used as a control group. Blood samples were collected for determination of blood level of Tn-I, and activity of CK-MB, LDH, and AST.

RESULTS

The obtained results revealed a highly significant increase in serum cTn I in diseased cattle with TP and TRP (P = 0.00), while buffaloes with TP showed no significant changes in serum cTn I (P = 0.111). Both diseased cattle and buffaloes showed increased serum activities of CK-MB, AST, and LDH enzyme. On the other hand, cardiac troponin I rapid test cassette failed to detect cTn I in diseased animals.

CONCLUSION

The study concluded that the cardiac troponin I rapid test cassette did not have a diagnostic significance and could not be used as a point-of-care under field condition for diagnosis of TP and TRP in large ruminants. However, the serum troponin I level is helpful in diagnosis of TP and TRP in cattle. Although cardiac biomarkers have some diagnostic values in TP and TRP, the traditional diagnostic methods (clinical, radiography and ultrasonography examinations) are crucial for thorough evaluation of TP/TRP cases in bovine.

Radiographic identification of challenging gastrointestinal tract foreign bodies: a descriptive study of how appearance varies in air versus water to aid interpretation

OBJECTIVE

To provide veterinarians with updated radiographic descriptions of select radiolucent foreign material in a simulated gastrointestinal environment.

SAMPLE

368 veterinarian respondents from the US.

METHODS

An online survey was administered between June 18, 2023, and July 2, 2023, through a private veterinarian-based social media group. Representative commonly ingested foreign bodies were radiographed surrounded by air and water to simulate being within the gastrointestinal tract. Two examiners evaluated and qualified the opacity of the objects for each environment.

RESULTS

The private social media group had a total of 3,900 members including veterinarians from all disciplines. A total of 362 small animal veterinarians (9.3% of the group) responded to the study reporting a total of 123 foreign objects that were not causing mechanical obstruction at the time of initial presentation. Sixty-eight foreign bodies were reported greater than or equal to 5 times and grouped as balls (n = 4), food (9), fabric (14), wood (3), soft plastic (14), hard plastic (18), or other (6). Most (98.5% [67/68]) objects were easily identifiable in air. In water, 23.5% (16/68) of the objects were obscured, and 39.7% (27/68) had inversion of the major opacity when compared to the opacity in air.

CLINICAL RELEVANCE

The opacity of some ingested radiolucent material can invert relative to air or fluid, which may reflect substantial differences in detection following repositioning. When known dietary indiscretion occurs, radiographing a sample of the material in air and water will improve the accuracy of assessment.

Enterolith with a bonefish spine nidus in a Brazilian cownose ray Rhinoptera brasiliensis (Müller & Henle) (Myliobatiformes: Rhinopteridae)

An adult female Brazilian cownose ray (Rhinoptera brasiliensis), housed in Ubatuba Aquarium died after loss of appetite period. During necropsy, an enterolith was discovered partially obstructing the intestinal lumen. Examination of the enterolith revealed a bonefish spine nidus. Enterolithiasis has been linked to multiple factors including diet, genetics, alkaline intestinal environments and, as in this particular case, the ingestion and retention of foreign bodies. The composition of this enterolith from a cownose ray was primarily monohydrocalcite. This short communication, apparently the first to report enterolithiasis in stingrays, emphasizes the need for post-mortem examinations of carcasses on macroscopic and microscopic levels.

Magnet-assisted endoscopic removal of ferromagnetic metallic gastric foreign bodies in 4 dogs

OBJECTIVE

Describe presenting signs, diagnostic findings, and magnet-assisted endoscopic removal method of ferromagnetic gastric foreign bodies (FBs) in dogs.

CLINICAL PRESENTATION

Four dogs presented with ingestion of sharp metallic FBs. The presence of gastric FBs was confirmed by abdominal radiography.

RESULTS

In 3 cases, initial attempts at endoscopic removal were unsuccessful because of ingesta and fluid in the stomach. A magnet contained within a Roth net was introduced endoscopically. Magnet and attached objects were successfully removed from the stomach. In the fourth case, removal with a magnet was judged to be the most expedient method of removal because multiple metallic objects were present.

CLINICAL RELEVANCE

An endoscopic technique was used for the removal of difficult-to-visualize or multiple metallic FBs. The use of this technique allows the removal of ferromagnetic gastric FBs without surgery or risk of complications associated with the passage of sharp material through the gastrointestinal (GI) tract.

A case report of live-stranded rough-toothed dolphin (Steno bredanensis) with plastic debris ingestion on the Pacific coast of Japan

A juvenile rough-toothed dolphin (Steno bredanensis) was live-stranded and rescued in Kanagawa Prefecture, Japan. From the results of diagnostic examinations, blood tests indicated that the dolphin was malnourished, dehydrated, and anemic. The dolphin died on sixth day of rescue despite treatment. At autopsy, 570 g of foreign material, including 34 pieces of cellophanes and plastic debris (PD), were found in the forestomach. Additional gross findings, including some endoparasitism and presence of accessory spleens were also identified. This is the first case in Japan which accidental ingestion of foreign bodies, including PD, was suspected to be the cause of death in a cetacean.

Clinical manifestations, endoscopic findings and outcomes of tonsillar fossa foreign bodies in dogs: seven cases (2020-2023)

OBJECTIVES

Clinical presentation and outcomes of dogs with tonsillar foreign bodies are not described in the literature. The objective of this case series is to describe the presence, clinical manifestations, endoscopic findings and outcomes of foreign bodies in the palatine tonsillar fossa of dogs.

MATERIALS AND METHODS

Medical records of dogs in which tonsillar fossa foreign bodies were removed by endoscopy between 2020 and 2023 at a referral centre were reviewed. Dogs were included if complete medical records were available.

RESULTS

Seven dogs were included. Among all clinical signs reported, acute onset of throat clearing occurred in all dogs. Palatine tonsil enlargement and protrusion from the tonsillar fossa were observed in four of seven dogs. Foreign bodies were removed under endoscopic guidance in all dogs; a vegetal foreign body was found in all but one dog (6/7). Complete resolution of clinical signs was reported in the five dogs for which follow-up information was available.

CLINICAL SIGNIFICANCE

The tonsillar fossa is a rare but possible location for foreign bodies in dogs and should be explored even in the absence of macroscopic lesions of the tonsils, since some dogs could have a normal palatine tonsil appearance. Acute throat clearing should raise the suspicion of tonsillar fossa foreign bodies. The prognosis appears good after removal.

Computed tomography of a canine omental torsion secondary to a chronic abdominal gossypiboma and concurrent incidental broad ligament torsion

A 5-year-old female spayed Dogue de Bordeaux was referred for concerns of an abdominal mass and peritoneal effusion. Abdominal radiographs identified a mid-ventral abdominal soft tissue opaque mass containing a radiopaque marker consistent with a gossypiboma. Contrast-enhanced abdominal CT identified two whirl signs associated with the abdominal gossypiboma. Exploratory laparotomy confirmed an omental torsion with encapsulated gossypiboma and concurrent incidental torsion of the remnant of the right broad ligament. Based on a literature review, omental torsions are an unreported complication of gossypibomas in canids.

CT findings in seven dogs with perforating wooden skewer foreign bodies from the gastrointestinal tract

Background

Perforating foreign bodies from the gastrointestinal tract, such as wooden skewers, are reported in the small animal literature producing inflammatory/infectious lesions in the thorax, abdomen, and musculoskeletal system, which can be life-threatening in some instances. Several imaging modalities have been used, and advanced imaging techniques have shown a great advantage in its diagnosis and pre-surgical planning.

Aim

The objective of this study is to describe the computed tomographic findings in a group of seven medium to large breed dogs with perforating wooden skewers and foreign bodies migrated from the gastrointestinal tract.

Methods

The medical records database was searched for dogs with a suspected diagnosis of a perforating wooden foreign body migrated from the gastrointestinal tract in which a computed tomographic study was performed. Signalment, history, and clinicopathological findings (when available) were retrieved, and the computed tomographic studies were reviewed.

Results

Clinical signs vary depending on the anatomical regions affected through the perforating pathway. All foreign bodies were identified and showed a median attenuation of 79 HU, with the most common localization being the stomach followed by the jejunum. Peritoneal fat stranding surrounding the perforation site was the most frequent computed tomographic finding. The presence of peritoneal free fluid and/or gas was uncommon. Pleural effusion, pulmonary perforation, and pneumothorax were present in most of the cases with the foreign body traversing the pleural space. Pulmonary cavitary lesions were always reported when the ending tip of the wooden skewer was within the pulmonary parenchyma. Soft tissue abscessation was recognized in all cases where the ending tip was lodged in muscular or subcutaneous tissues.

Conclusion

Findings supported the variability of the secondary lesions caused by this type of foreign body and the utility of computed tomography in their recognition, as well as in the identification of the wooden skewer.

Clinical findings, surgical treatment and outcome in dogs with parotid duct ectasia: 14 cases (2010-2023)

OBJECTIVES

To describe the clinical presentation, diagnostic findings, surgical treatment and outcome of dogs diagnosed with parotid duct ectasia.

MATERIALS AND METHODS

Medical records of dogs diagnosed with parotid duct ectasia between 2010 and 2023 at six small animal referral hospitals were retrospectively reviewed. Outcome was assessed by contacting the owners or referring veterinarians.

RESULTS

Fourteen dogs were included. Lateral facial swelling was the most common clinical presentation. CT revealed a tortuous cavitary tubular fluid-filled structure consistent with a dilated parotid duct in all dogs. Surgical treatment included marsupialisation of the parotid duct papilla, surgical exploration of the duct alone, parotid duct marsupialisation with surgical exploration of the duct, parotidectomy or en-bloc parotid duct resection. The aetiology of parotid duct ectasia was not established in 13 of 14 dogs. In one case, a foreign body was retrieved from the duct. No recurrence of clinical signs was noted during the follow-up period (range 21 to 2900 days).

CLINICAL SIGNIFICANCE

Parotid duct ectasia should be considered for dogs with a lateralised fluctuant non-painful tubular facial swelling. Surgical management was associated with a favourable prognosis without evidence of recurrence in all cases reported in the case series.

Endoscopic Removal of Gastric Foreign Bodies with a Bottle Liner in 12 Dogs (2020-2023)

Endoscopy is widely used to remove gastric foreign bodies using grasping forceps and loop snares to manipulate and retrieve the foreign material. However, as not all foreign bodies can be removed using conventional endoscopic techniques, this case series describes the use of bottle liners for the removal of gastric foreign bodies in 12 dogs between 2020 and 2023. A 4 oz bottle liner (Drop-Ins) was placed at the end of the endoscope and pushed into the stomach. With the help of forceps introduced into the operating channel, the foreign body was pushed into the bottle liner. The bottle liner containing the foreign body was then extracted with the help of traction threads. The technique was used as the initial retrieval method in 5 dogs because of smooth (i.e., difficult to grasp) or sharp (i.e., that may damage the digestive tract mucosa during removal) foreign bodies and as a rescue procedure in 7 dogs. Foreign body retrieval was successful in all 12 dogs, with minor complications reported in 5 dogs (erosions and bleeding of the gastroesophageal sphincter). The use of a bottle liner represents an affordable alternative to gastrotomy when foreign bodies cannot be grasped with forceps or snares.

Minimal adverse events occur when inducing emesis with apomorphine in brachycephalic, mesocephalic, and dolichocephalic dogs

OBJECTIVE

To determine risks of complications with emesis induction and whether facial conformation is associated with the frequency of complications.

ANIMALS

1,788 client-owned dogs that presented immediately or by referral from a primary care veterinarian following ingestion of toxic or foreign materials.

METHODS

Patients with emesis induced with apomorphine for removal of toxic or foreign materials were retrospectively identified. Collected data included patient factors, routes of apomorphine administration, other therapies, adverse events, and patient outcomes.

RESULTS

2 types of complications were identified in a very small number of patients (11 [0.6%]), with 3 (0.17%) having regurgitation postemesis and 8 (0.44%) having prolonged vomiting. No significant difference was found in the rates of repeated vomiting or regurgitation between brachycephalic dogs and nonbrachycephalic dogs (P = .375 and P = 1.00, respectively). Brachycephalic dogs had 1.6 times greater odds of having emesis induction due to toxin ingestion compared to foreign material ingestion. The presence of clinical signs of toxicity at the time of emesis induction was associated with regurgitation (P < .001), and the development of regurgitation was associated with admission to hospital (P = .001).

CLINICAL RELEVANCE

This study found no increased risk of complications when emesis was induced using apomorphine in brachycephalic breeds compared to nonbrachycephalic breeds, regardless of indication for emesis induction. Facial conformation is not a reason to withhold emesis induction.

Depraved appetite in dromedary camels: Clinical, ultrasonographic, and postmortem findings

Background

Camels are subjected to a wide variety of nutritional deficiencies as they are largely dependent upon grazing desert plants. As a consequence, the syndrome of pica or depraved appetite is occasionally seen in dromedary camels. The condition is manifested as chewing or eating abnormal things such as wood, dirt, bones, stones, clothes, plastics, mud, sand, or other inanimate objects.

Aim

This study was designed to investigate the clinical, ultrasonographic, and postmortem findings in dromedary camels with pica or depraved appetite.

Methods

Twenty-five camels of 5 days to 15 years were examined. Owner complaints included depraved appetite, loss of body condition, regurgitation of stomach content, and partial or complete absence of feces. Symptoms described were present for a period varying between 3 days, up to 12 months. The stomach compartments and small and large intestines were scanned using ultrasonography from the right and left sides of the abdomen. Necropsy was carried out on six female and three male camels where the thoracic and abdominal organs were examined with special attention to the digestive system.

Results

The affected animals had a history of gradual loss of body conditions, eating foreign objects, decreased or total absence of feces, and regurgitation of stomach content. Using ultrasound, the foreign body was imaged occluding completely or partially the intestines. Foreign bodies within the rumen could not be visualized with ultrasound. In cases where the rumen is impacted by sand, small pin-points revealing acoustic enhancement were imaged. Foreign bodies were removed from the rumen at exploratory rumenotomy (n = 11), laparotomy (n = 3), or at necropsy (n = 8) in the form of plastics, cloths, sand, mud, wool balls, robes, glasses, or even metallic objects which may be blunt or sharp. Sixteen (64%) of the camels were recovered while the remaining 9 (36%) did not survive.

Conclusion

The syndrome of pica or depraved appetite is an important condition in dromedary resulting in the ingestion of objects other than normal feed. Substantial economic losses are expected as a result of this syndrome. Ultrasonography of the digestive system may help the clinician in some cases to localize of occluding foreign bodies in the intestines, while in the transabdominal scanning of the stomach is valuable only in cases of sand impaction.

Jejunal perforation and septic abdomen resulting from a choristoma in a dog

A 4.6-year-old spayed female German shepherd dog was admitted to a specialty hospital emergency service upon referral for suspected gastrointestinal foreign body obstruction. Free abdominal fluid was collected, and results of cytologic evaluation were consistent with a septic abdomen. An abdominal barium study revealed free gas and intraperitoneal barium, along with an obstructive gas pattern within the small bowel. Ultrasonography revealed a full-thickness jejunal perforation. On exploratory laparotomy, the perforation was noted to be located mid-jejunum with no associated mass or foreign material. A resection and anastomosis were completed. Histopathologic evaluation of the affected jejunal tissue showed aberrant gastric glandular epithelium consistent with a gastric choristoma, or heterotopic gastric tissue. Key clinical message: Clinicians should consider gastric glandular choristoma as a differential diagnosis in cases of seemingly idiopathic small intestinal perforation with no known cause (i.e., foreign body penetration, neoplasia, NSAID use), and histopathologic evaluation should always be done to obtain a definitive diagnosis.

USE OF HYSTEROSCOPIC MORCELLATION WITH A MYOSURE® DEVICE FOR REMOVAL OF UTERINE FOREIGN MATERIAL IN AN ORANGUTAN (PONGO SP.)

A 36-yr-old female intact hybrid orangutan (Pongo sp.) presented with evidence of chronic bacterial cystitis with no response to treatment with multiple systemic antibiotics. Abnormalities were identified within the reproductive tract on CT scan, and hysteroscopy was pursued based on the recommendation of an obstetrician-gynecologist. Hysteroscopic examination revealed a large amount of intrauterine foreign material consistent with wood wool from the orangutan's bedding. A hysteroscopic morcellator (MyoSure®) was used to remove the foreign material. Histologic examination of endometrial biopsies showed severe suppurative to pyogranulomatous endometritis with intralesional foreign (wood) fibers and bacteria. The orangutan was treated with antibiotics, but evidence of bacterial cystitis persisted. After 15 wk, additional wood wool was identified within the uterus by hysteroscopic examination and was removed similarly. Five months later, there was no recurrence of foreign material on hysteroscopy or CT. This report describes the first documentation of intrauterine foreign material in a nonhuman primate. Hysteroscopic morcellation is a useful technique for noninvasive removal of intrauterine foreign material in great apes.

Diagnosis and treatment of traumatic reticulitis associated with abomasal obstruction in beef cattle during late pregnancy: A case report

Background

Traumatic reticulitis (TR) and abomasal obstruction are common digestive diseases in beef cattle. In clinical practice, these two conditions are often detected alone and rarely occur at the same time. Surgical therapy is an effective approach to treat both of these diseases. However, there are no reports on the treatment of abomasal obstruction in cattle induced by TR.

Case Description

We here report a rare case of the diagnosis and treatment of TR associated with abomasal obstruction in a beef cow during late pregnancy. The affected cattle had an iron wire that was piercing the wall of the reticulum, but did not penetrate the wall; the abomasum was blocked and appeared solid; and the fetus survived well in utero (268 days gestation). To save the lives of the cow and fetus on the same day, a cesarean section was first performed, followed by rumenotomy, the foreign body (wire) was removed, and abomasotomy was finally performed. The fetus removed by cesarean section grew well, and the beef cow recovered and successfully became pregnant again.

Conclusion

This case thus offers guidance for the timely diagnosis, effective treatment, and postoperative management of these digestive diseases in cattle to prevent progression and further complications.

Successful intraoperative ultrasound-guided retrieval of intracranial grass seed foreign body in a 4-month-old puppy

A 4-month-old female-entire Vizsla dog was referred for progressive seizure activity, vomiting, lethargy, inappetence, and neck pain. CT revealed focal inflammation, a calvarial osseous defect, a possible foreign body within the brain, and associated vasogenic edema. A cerebrospinal fluid tap revealed marked septic neutrophilic pleocytosis. MRI findings supported diagnosis of a 1.7 cm foreign body within the brain. A right rostrotentorial craniectomy was performed, and intraparenchymal grass seed was removed in its entirety via intraoperative ultrasound guidance. The patient was discharged 2 days postoperatively, and long-term follow-up revealed no abnormal neurological signs.

Infrared thermography is a novel tool to assess small intestinal surface temperature in dogs undergoing laparotomy for foreign body obstruction

OBJECTIVE

To evaluate local temperature differences directly over and adjacent to small intestinal foreign body obstruction (FBO) using infrared thermography (IRT) in dogs.

ANIMALS

49 client-owned dogs were initially enrolled.

METHODS

In a prospective, clinical observational study, IRT was utilized to compare median small intestinal (SI) surface temperature differences at the site of FBO and segments oral and aboral before and after surgical resolution from April 24, 2019, to July 19, 2020. These differences were evaluated for correlation with canine acute patient physiologic and laboratory evaluation fast (APPLEfast) scoring, lactate, foreign body material (hard vs soft), and blood pressure.

RESULTS

There was not a significant surface temperature difference between SI segments at the site of FBO, oral or aboral. After resolution of obstruction, there was a significant decrease in median temperature directly over the FBO (2.4 °C; IQR, -2.55 to 10.6 °C; P = .0043). A decrease in surface temperature of the oral SI segment was appreciated with FBO due to hard material (-1.7 °C; IQR, -5.2 to 3.4 °C), whereas soft material had an increase in SI surface temperature oral to the FBO (+1.1 °C; IQR, 0.3 to 3.2 °C). This difference did not achieve significance (P = .08; Z = 1.75). No correlation was found between APPLEfast, lactate, or blood pressure and SI segment temperatures.

CLINICAL RELEVANCE

IRT may be useful diagnostic modality to identify changes in small intestinal surface temperature relating to FBO. Further evaluation is warranted to determine if IRT may be a clinically useful to evaluate intestinal perfusion.
