A young female Boxer had a history of chronic soft stool. Survey abdominal radiographs were unremarkable. A duodenal diverticulum was identified in abdominal ultrasound and barium upper-gastrointestinal contrast examinations. Before surgery a 99m Tc-pertechnetate study was performed to evaluate for ectopic gastric mucosa in the duodenal diverticulum. Focal abnormal increased radioactivity was identified in the right caudal abdominal quadrant. The diverticulum was excised. Upon histopathologic examination of the duodenal diverticulum, ectopic gastric mucosa was not identified but ectopic pancreatic tissue was found. Mild eosinophilic inflammation within the diverticulum was suspected to be the cause of the mild 99m Tc uptake seen in this dog. 相似文献

A 16-year-old rhesus monkey with perineal swelling and urinary obstruction was found to have a congenital urinary bladder diverticulum. Because the diverticulum was located at the trigone, its distention partially obstructed the urethra, resulting in incomplete voiding. The diverticulum was resected and did not redevelop. 相似文献

Meckel's diverticulum is a remnant of the vitellointestinal duct. It is through this duct that nutrients pass from the yolk sac into the midgut of the four-week-old embryo. In a review of 15,000 postmortem records at the University of Kentucky, Meckel's diverticulum was observed in five horses examined postmortem. In each case, the diverticulum was a factor in the animal's death. In light of these statistics, Meckel's diverticulum may not be as frequent a finding in the horse as has been previously considered. 相似文献

A 4-year-old Thoroughbred gelding with a history of chronic colic was referred for evaluation of signs of abdominal pain. Exploratory laparotomy revealed a diverticulum of the distal portion of the ileum located between the layers of the mesentery. The diverticulum was similar in location and appearance to acquired ileal diverticula described in human beings. Complete bypass of the diverticulum by ileocecostomy resulted in apparent resolution of the chronic colic in this horse. 相似文献

A 14-month-old, male German shepherd dog was evaluated for chronic, recurrent Escherichia coli urinary tract infection. An initial diagnosis of emphysematous cystitis was made, which resolved with appropriate antibacterial therapy. The urinary tract infection, however, did not resolve and on further investigation a bladder trigone diverticulum was evident, thought to be congenital in origin. This report describes the apparent ultrasonographic and radiological changes, and surgical repair of the diverticulum, and reviews the literature with regard to both congenital bladder trigone diverticulum and emphysematous cystitis. The former has never been documented in the dog and the latter is an unusual finding in a non-diabetic dog. 相似文献

An intrathoracic esophageal pulsion diverticulum causing repeated episodes of esophageal obstruction in a Morgan weanling colt was diagnosed by endoscopy, positive contrast radiography, and pleuroscopy. Surgical excision of the diverticulum alleviated clinical signs, and the horse was able to resume a normal diet by day 6. After 9 months the colt remains asymptomatic. 相似文献

A 3-month-old, female Holstein calf was examined because of marked perineal swelling and tenesmus of 4-days duration. A congenitally enlarged urethral diverticulum was diagnosed using fluoroscopic and ultrasonographic imaging techniques. The urethral diverticulum was surgically resected and the perineal area was reconstructed. 相似文献

A one‐year‐old intact male German shepherd dog was referred with a 3‐month history of dysuria and pollakiuria. Physical examination revealed a large firm mass in the caudal abdomen. Findings from survey radiography, negative contrast cystography, computed tomographic (CT) retrograde positive contrast cystography, and CT excretory urography were consistent with a large urinary bladder diverticulum. An exploratory laparotomy revealed a normal wall appearance in the ventral compartment (true bladder) and marked thinning of the wall in the dorsal compartment (diverticulum). Both ureters inserted into the ventral compartment. The dorsal compartment was excised and histopathology confirmed the diagnosis of urinary bladder diverticulum. 相似文献

This is a report of a 12-year-old Swedish Warmblood gelding with a ruptured esophageal pulsion diverticulum associated with atypical clinical signs of colic and septic peritonitis on presentation. The location of this diverticulum at the hiatus was unique and was most likely responsible for the unusual presentation of this horse. 相似文献

We report use of esophagomyotomy and esophagopexy to create a diverticulum for relief of chronic type I esophageal stricture in 2 horses. After esophagomyotomy, the mucosa was dissected free from the muscularis for approximately 180 degrees around the myotomy. Then, the tunica muscularis of esophagus was sutured to the sternocephalicus muscle ventrally and the periesophageal tissues dorsally to create a diverticulum without disruption of the esophageal mucosa. Clinical signs of esophageal stricture were relieved, and the horses were fed normal diets without further esophageal obstruction. 相似文献

A 23-year-old Thoroughbred stallion was admitted to the hospital for treatment of acute esophageal obstruction. Clinical examination and contrast radiography confirmed the presence of an esophageal obstruction. The horse was euthanatized, and examination revealed a bolus of feed material occluding the esophageal lumen 6 cm caudal to the thoracic inlet, with underlying necrosis of the esophageal mucosa. A large pulsion diverticulum was identified in the caudocervical portion of the esophagus. Apparently, the phytobezoar was formed within the esophageal diverticulum and subsequently became dislodged, occluding the esophagus. 相似文献

A 9‐year‐old Arabian stallion was presented for evaluation of recurrent colic problems of 2 years' duration. These colic episodes were associated with a right sided abdominal distension. An exploratory laparotomy revealed a colonic diverticulum that was resected en bloc. Two days later, following signs of acute colic, a second laparotomy showed incarceration of the distal jejunum into a mesodiverticular band combined with haemorrhage of a mesenteric arterial branch. In addition, an abnormally short jejunum (10 m) was also observed. An end‐to‐end jejunojejunostomy was performed. Following surgery the horse developed septic peritonitis, ptyalism and became dysphagic. Ten days after the second surgery, an infected oesophageal diverticulum causing regional inflammation was diagnosed endoscopically and euthanasia was performed. Post mortem examination showed a 40 cm long diverticulum lateral to the oesophagus. Histology suggested a congenital nature of the colonic and oesophageal diverticuli. 相似文献

Esophageal diverticulum and perforation were diagnosed in a horse. The condition was characterized clinically by dysphagia, polypnea, diffuse swelling of the ventral aspect of neck and cutaneous fistula. Endoscopic examination revealed the presence of food material in the guttural pouch. A barium sulfate esophagram was performed to outline the diverticulum.
Exploratory surgery confirmed esophageal perforation and entrapment of food material between the muscular planes of the cervical region and the horse was euthanized. At necropsy a food-filled periesophageal tract was found extending from the esophageal rupture to the left guttural pouch.

The aim of the study was to describe the air sacs of the rock partridge. The sacs of 15 adult birds were cast by injection of latex via the trachea and then corroded with 30% KOH at 40 degrees C. The morphology of the sacs was in general similar to that of other avian species described in the literature. There were, however, significant characteristics such as an additional subcutaneous diverticulum of the cranial thoracic sac and a caudally pointing diverticulum of the cervical sac located between the lungs. 相似文献

A neutered female chow chow aged six years and five months was evaluated for dysuria. An initial diagnosis of bladder distension and atony was made following physical, ultrasonographic and radiographic examinations. The problems did not resolve with medical management and exploratory surgery revealed a large bladder diverticulum. This report describes the radiographic findings and surgical repair of the acquired bladder diverticulum. The literature available on this condition is also reviewed. 相似文献

Older male dogs often exhibit the symptoms of rectum diverticulum and perineal hernia. In order to point out the often common reason of these disorders, the term "rectum diverticulum/perineal hernia complex" has been introduced. In a large group of such patients two methods of surgical correction of this problem were retrospectively evaluated. Only patients were included in this evaluation that were euthanized if recurrence occurred. In 21 patients (group 1) the often performed method of Bojrab was used, both in rectum diverticulum and in perineal hernia operations. In group 2 15 dogs were subjected to the same operation technique, but we performed an additional pleating contraction of the herniated gut wall layers. In case of visible recurrence at an age of at least 11 years the dogs were euthanized. Group 1 showed a postoperative survival time of 3.61 +/- 0.96 years until recurrence, group 2 revealed recurrence not before 4.93 +/- 0.93 years post operationem. The difference is significant (p < 0.05). It is the opinion of the authors that additional longitudinal contracting by pleating of the gut markedly prolonges the point of time when recurrence appears. 相似文献

Surgical management of a large colorectal diverticulum in a dog A 10-year-old crossbred dog had a lour month history of intermittent rectal prolapse. Castration and use of stool softeners had been attempted to control tenesmus and obstipation. Examination per rectum was normal. Three months later colopexy was performed and the dog began defecating normally immediately after surgery. After one month, obstipation and tenesmus returned. Initially, faeces were misshapen and ribbon-like, then defecation stopped. Palpation per rectum revealed a band-like ventral mucosal fold approximately 6 cm Irom the anus. A contrast study demonstrated a large (4X2 cm), well-defined diverticulum in the colorectum. Diverticulectomy was performed using a surgical stapling device, which allowed rapid excision and substantially reduced risk of faecal contamination. Recovery was good and the dog remained clinically normal, although a slight narrowing of the colorectum was seen radiographically. 相似文献

Single-shot turbo spin-echo sequences are heavily T2-weighted sequences that are exceptionally well suited to evaluate the subarachnoid space. In the T2-weighted fast spin-echo sequences that are used routinely in spinal magnetic resonance (MR) imaging, the subarachnoid space is not well differentiated from the surrounding epidural fat, which could lead to decreased detection of lesions of the subarachnoid space such as arachnoid diverticula. Our purpose was to determine the added value of a single-shot turbo spin-echo sequence in identifying cystic lesions of the subarachnoid space in dogs. MR images of six dogs with a confirmed arachnoid diverticulum and 24 dogs with other spinal disease were included. Six observers were asked to interpret only T2-weighted images initially, and in a second session, T2-weighted and half-Fourier acquisition single-shot turbo spin-echo (HASTE) sequences. The MR images were anonymized, and no signalment, history, or clinical information was provided. Without the HASTE sequences, 25% of arachnoid diverticula were identified. Adding the HASTE sequence increased the diagnosis of arachnoid diverticulum to 52.8%. The resulting difference, after adding the HASTE sequence, of 27.8% was statistically significant (P = 0.002). No false-positive diagnoses of arachnoid diverticulum were made with either sequence. Although sensitivity in this study was likely artificially low, the significantly increased detection rate of arachnoid diverticula when using HASTE imaging indicates that this sequence is a valuable addition to MR imaging protocols for the canine spine. 相似文献
