Paraesophageal hiatal hernia and pyloric obstruction in a dog 总被引：1，自引：0，他引：1
K G Miles E R Pope A E Jergens 《Journal of the American Veterinary Medical Association》1988,193(11):1437-1439
Paraesophageal hiatal herniation and pyloric obstruction were diagnosed in a pup with a history of vomiting. Findings of contrast radiography included esophageal reflux, delayed gastric emptying time, and paraesophageal herniation. Exploratory celiotomy revealed increased firmness of the pylorus and a primary defect in the esophageal hiatus, which allowed gastric herniation. Nissen fundoplication was performed following reconstruction of the esophageal hiatus, and pyloroplasty was performed to relieve the gastric outlet obstruction. Pyloric biopsy findings were consistent with a diagnosis of chronic gastritis. Recovery from surgery was initially unremarkable; however, the dog died suddenly 3 weeks after surgery. Necropsy revealed a large diaphragmatic hernia adjacent to the esophageal hiatus; the hernia had resulted in incarceration of the abdominal organs. The hiatal hernia reconstruction remained intact and was not the cause of the diaphragmatic disruption. 相似文献

OBJECTIVE: To describe clinical findings, surgical treatment, and outcome associated with trichophytobezoar duodenal obstruction in New World camelids. STUDY DESIGN: Retrospective study. ANIMALS: Alpacas (7) and 1 llama. METHODS: Historical and clinical data were obtained from the medical records of New World camelids with a diagnosis of trichophytobezoar duodenal obstruction confirmed by surgical exploration or necropsy. RESULTS: Seven camelids were <1 year old. Abnormal clinical findings included anorexia, reduced fecal output, recumbency, colic, abdominal distension, regurgitation, decreased serum chloride concentration, increased serum bicarbonate concentration, and/or elevated first gastric compartment chloride concentration. Survey abdominal radiographs obtained (4 animals) revealed gastric distension (4) and/or visualization of the obstruction (2). Diagnosis was confirmed at necropsy (1) or surgery (7). Right paracostal celiotomy was performed on all animals and duodenotomy (3) or retropulsion of the trichophytobezoar combined with third compartment gastrotomy (4) was used to remove the obstruction. Six animals survived to discharge and 5 were healthy at follow-up, 8-20 months later. The remaining discharged alpaca was healthy at 12 months but subsequently died of unrelated causes. CONCLUSIONS: Diagnosis of trichophytobezoar duodenal obstruction should be considered in juvenile New World camelids with abdominal distension and hypochloremic metabolic alkalosis. Right paracostal celiotomy can be used for access to the descending duodenum and third gastric compartment for surgical relief of obstruction. CLINICAL RELEVANCE: Duodenal obstruction from bezoars should be considered in New World camelids <1year of age with abdominal distension and hypochloremic metabolic alkalosis. Surgical relief of the obstruction by right paracostal celiotomy has a good prognosis. 相似文献

A six-year-old male silkie terrier presented with a history of chronic vomiting. A diagnosis of gastric outflow obstruction was made using contrast radiography of the upper gastrointestinal tract. Surgical examination of the stomach revealed thickened pyloric antral mucosa. A Heineke-Mikulicz pyloroplasty combined with resection of the hypertrophic pyloric mucosa were performed to increase the patency of the pyloric lumen. The dog recovered well from surgery and his condition remained stable until the sixth day postoperatively when his condition deteriorated rapidly resulting in his death that night. At autopsy a perforated gastric ulcer was found in the cardiac region of the pylorus with evidence for a generalised peritonitis. An association between gastric outflow obstruction and gastric ulceration has been reported in human clinical literature and in canine experimental models. No such association has been previously documented in the veterinary clinical literature. 相似文献

Gastric drainage procedures are commonly used in veterinary medicine, particularly in dogs in attempts to prevent recurrence of gastric dilatation-volvulus (GDV). The following five different procedures have been most commonly described: the Fredet-Ramstedt pyloromyotomy (FRP); Heineke-Mikulicz pyloroplasty (HMP); Finney pyloroplasty (FP); Jaboulay's gastroduodenostomy (JG); and antral gastrojejunostomy (AG). These surgical procedures have not been compared in a controlled study. This first article of a series of three describes the gastric drainage procedures performed in 30 normal dogs for a comparative study. The FRP and HMP were the fastest and easiest procedures to perform. The degree of difficulty was found to be increased but similar for FP, JG, and AG. No complication occurred during or immediately after surgery. 相似文献

Rabbits that have sudden onset anorexia commonly present to veterinary practices with dilated stomachs. Postmortem examination or surgical investigation often identifies the underlying etiology of the gastric dilation as small intestinal obstruction. The condition is frequently fatal if left untreated, but protocols for diagnosis and treatment have not been established. This article attempts to clarify diagnosis of the condition by clinical and radiographical signs, as well as providing a guide to the management of these difficult cases. With appropriate decision making and treatment, the prognosis for small intestinal obstruction in rabbits can be dramatically improved. 相似文献

Canine gastric adenocarcinoma and leiomyosarcoma: a retrospective study of 21 cases (1986-1999) and literature review 总被引：1，自引：0，他引：1
This retrospective study describes the clinical course, treatment, and outcome of 21 dogs with gastric adenocarcinomas (n=19) and leiomyosarcomas (n=2). Medical records from 1986 to 1999 were reviewed for signalment, weight, diagnosis, tumor location, clinical signs, radiographic imaging procedures, surgical procedures, chemotherapy, duration of follow-up monitoring, outcome, cause of death, metastatic rate, metastatic sites, and method of detection of metastasis. Fourteen of 19 (74%) dogs with gastric adenocarcinomas had metastasis. Metastatic sites included gastric lymph nodes, omentum, liver, duodenum, pancreas, spleen, esophagus, adrenal glands, and lungs. Both cases of a gastric leiomyosarcoma had metastatic disease involving the liver (n=2) and duodenum (n=1). Surgery, consisting of either a Billroth I or a gastrojejunostomy, provided immediate relief of the gastric outflow obstruction and clinical improvement in the early postoperative period. The beneficial effects of chemotherapy alone or adjuvant chemotherapy are still unknown. Recurrence of clinical signs 3 days to 10 months after surgery caused all owners to elect euthanasia. The long-term prognosis for most cases of gastric adenocarcinomas and leiomyosarcomas is poor because of the presence of advanced disease. Surgical resection, however, does alleviate gastric outflow obstruction in the immediate postoperative period. 相似文献

Reasons for performing study: It has been suggested that the success of gastric bypass surgery in foals for the treatment of gastric outflow obstruction is poor. However, few reports exist evaluating the long‐term prognosis of these cases. Objectives: To determine the long‐term success of foals, including racing records, surgically treated for gastric outflow obstruction secondary to gastroduodenal ulceration. Methods: Medical records of foals undergoing surgical treatment of gastric outflow obstruction secondary to gastroduodenal ulceration were evaluated for clinical information. Owners, trainers and race records were evaluated regarding long‐term survival and racing success. Results and conclusions: Sixteen foals were included in the study, all treated with a gastrojejunostomy. All foals survived to immediate discharge from the hospital; 8 survived to racing age, with 7 of those entering training and 3 actually racing. Foals that did not survive to racing age had various post operative complications. The success rate for these foals appears somewhat better than that previously reported. Potential relevance: Gastrojejunostomy for the treatment of gastric outflow obstruction, secondary to gastric ulceration, is a valid treatment option for foals. 相似文献

A modified castellated laryngofissure procedure (castellated laryngofissure, vocal fold resection, and bilateral arytenoid lateralization) was performed on 12 dogs with bilateral laryngeal paralysis. Clinical signs of airway obstruction were assessed and a pulmonary function test (tidal breathing flow volume loop) was used to evaluate the severity of obstruction. The dogs were evaluated before surgery and at various periods from 4 days to 15 months after surgery. One dog died immediately after surgery and 3 dogs died due to nonrelated or unknown causes 1, 9, and 11 months after surgery. Clinical signs of upper airway obstruction disappeared or decreased in severity in the 11 dogs that recovered from surgery. Tidal breathing flow volume loop values were normal in 7 of 10 dogs evaluated within 5 to 189 days after surgery. The modified castellated laryngofissure procedure provided successful long-term relief of upper airway obstruction associated with bilateral laryngeal paralysis. 相似文献

Eighty-four incidents of gastric dilation (bloat) were investigated in 76 pet rabbits, and an intestinal obstruction was confirmed in 64 of them. In 49 the obstruction was due to pellets of compressed hair, in four to locust bean seeds, in five to neoplasia, in two to postspay adhesions, and in one case each to carpet fibre, tapeworm cysts, a strangulated hernia and diverticulosis. In all but four cases, the obstruction was in the small intestine. The condition affected a variety of breeds fed on a variety of diets. Radiography was a useful diagnostic tool because gas and/or fluid in the digestive tract outlined the dilated stomach and intestines. Twenty-nine of the rabbits died or were euthanased without treatment, and 40 underwent exploratory surgery; of these, 10 died during surgery, three were euthanased because of intestinal neoplasia, eight died postoperatively and 19 recovered. Fifteen rabbits in which radiography indicated that a foreign body had passed out of the small intestine did not undergo surgery; of these, 13 recovered and two died. 相似文献

Intussusception is recognized as a common cause of bowel obstruction in small animals. This study documents the clinical and surgical findings in nine cats and 27 dogs diagnosed as having intussusception. The main purposes of the study were to define the predisposing causes and clinical signs of intussusception and to evaluate various surgical techniques commonly employed in its treatment. No common predisposing cause could be established. Diagnosis of intussusception was based most often on clinical signs of bowel obstruction in association with the palpable abdominal mass. The majority of the intussusceptions involved the enterocolic junction. Formation of adhesions was more frequent in cats. Surgical treatments included simple reduction, manual reduction with plication, intestinal resection/anastomosis, and intestinal resection/anastamosis with plication. There was no statistically significant difference (p>0.05) in the recurrence rate of the intussusceptions when the various surgical techniques were compared. Recurrence of an intussusception was not related to either the bowel segment involved or whether a simple reduction, bowel resection, or intestinal plication was performed at the initial surgery. 相似文献

An incision, or urethrotomy, is made into the urethral lumen to remove or relieve an obstruction temporarily. When permanent diversion of urine flow proximal to an obstructed, severely damaged, or diseased urethra is required, a urethrostomy is performed. Urethrostomy is also performed to diminish the risk of urethral obstruction due to recurrent urinary calculi that are not likely to be resolved with medical therapy. Whenever possible, to reduce the risk of urethral stricture or recurrent urinary tract infection, urethral surgery is avoided when an obstruction can be relieved by retrohydropropulsion or catheterization. Urethrotomy can be performed in the prescrotal or perineal regions depending on the level of the urethral obstruction. Although urethrostomy can be made in the perineal and antepubic positions, scrotal urethrostomy is the procedure of choice provided the lesion is distal to this area. Specific urethrotomy and urethrostomy procedures are described, including discussion about selection of the appropriate procedure for the urethral problem, patient stabilization considerations, general postoperative management, and risk of complications. 相似文献

A case of equine midcervical esophageal obstruction by medicinal boluses is described. A discussion of the physical and endoscopic examination is included. Attempts at medical and manipulative therapy including massage, intraesophageal probing and endoscopically assisted efforts to snare the obstruction were nonrewarding. A standing midcervical esophagotomy was performed to facilitate the removal of the entrapped boluses. A positive contrast esophagram obtained five days after surgery indicated an absence of leakage of contrast media from the lumen of the esophagus. The filly was returned to athletic competition at seven days following surgery. No evidence of dysphagia or esophageal obstruction was reported six months following surgery. In this particular case, a standing midcervical esophagotomy afforded a successful alternative when manipulative and medical therapy proved inadequate. 相似文献

Polyurethane adhesives are found in a large number of household products in the United States and are used for a variety of purposes. Several brands of these expanding wood glues (those containing diphenylmethane diisocyanate [MDI]) have the potential to form gastrointestinal (GI) foreign bodies if ingested. The ingested adhesive forms an expanding ball of glue in the esophagus and gastric lumen. This expansion is caused by a polymerization reaction using the heat, water, and gastric acids of the stomach. A firm mass is created that can be 4-8 times its original volume. As little as 2 oz of glue have been reported to develop gastric foreign bodies. The obstructive mass is reported to form within minutes of ingestion of the adhesive. The foreign body can lead to esophageal impaction and obstruction, airway obstruction, gastric outflow obstruction, mucosal hemorrhage, ulceration, laceration, perforation of the esophageal and gastric linings, and death. Clinical signs following ingestion include anorexia, lethargy, vomiting, tachypnea, and abdominal distention and pain, and typically develop within 12 hours. Clinical signs may depend upon the size of the mass. If left untreated, perforation and rupture of the esophagus or stomach can occur. The glue mass does not stick to the GI mucosa and is not always detectable on abdominal palpation. Radiographs are recommended to confirm the presence of the “glue-ball” foreign body, and radiographic evidence of the obstruction may be seen as early as 4-6 hours following ingestion. Emesis is contraindicated owing to the risk of aspiration of the glue into the respiratory tree or the subsequent lodging of the expanding glue mass in the esophagus. Likewise, efforts to dilute the glue and prevent the formation of the foreign body through administration of liquids, activated charcoal, or bulk-forming products to push the foreign body through the GI tract have proven ineffective. Even endoscopy performed to remove the foreign body has been shown to be unreliable. The safest, most effective, and successful therapy is surgical intervention to remove the GI foreign body. If performed early enough, complete recovery of the animal can be expected. Differential diagnoses for polyurethane adhesive ingestion include any potential cause of GI obstruction. The public is largely unaware of the hazards that ingestion of this product may produce. Public education efforts are needed to inform pet owners about the hazards of these glues and the overall importance of providing our companion animals with safe, poison-free environments. 相似文献

Gastroenterostomy was performed in 14 foals to treat gastric outflow obstruction caused by advanced gastroduodenal ulcer disease. The onset of excessive salivation and teeth grinding, without response to medical treatment, combined with endoscopic and radiographic evidence of gastric outflow obstruction, were indications for surgical intervention. Successful outcome in 5 foals was attributed to early diagnosis, patient stabilization, early surgical correction, and postoperative management including antibiotics and antiulcer medication. 相似文献

Six small-breed, middle-age dogs with a history of chronic intermittent vomiting had benign pyloric lesions causing gastric outlet obstruction. Marked similarities were found in clinical signs, pathologic changes, and treatment results. The condition was classified as a syndrome and was named chronic hypertrophic pyloric gastropathy. The appearance of the obstructive lesions at surgery were various forms of mucosal hypertrophy. Microscopically, the syndrome was characterized by mucosal foveolar and glandular hyperplasia, cystic glandular dilatation, superficial mucosal ulcerations, and various cellular infiltrates. The affected dogs were successfully treated by surgical correction of the gastric outlet obstruction. 相似文献

Intestinal obstruction by radiolucent foreign bodies is common in sea turtles. The absence of clinical signs and the extended fasting periods in these animals means that intestinal obstructions may not be diagnosed early. Digestive tract radiographic contrast procedures were performed to evaluate the gastrointestinal transit time and intestinal obstructions in loggerhead sea turtles. Barium sulfate and nonionic iodinate contrast medium were used for radiographic contrast procedures. Contrast medium was administered via a gastric tube or into the colon. These procedures are often necessary and are useful to document intestinal obstruction and foreign objects. The diagnostic procedures were not easily performed in some turtles, but often they were adequate for the diagnosis. 相似文献

Four adult horses with histories of moderate abdominal pain and inappetence were diagnosed with delayed gastric emptying and gastric impaction attributed to pyloroduodenal obstruction (three cases) or duodenitis (one case). A stapled side-to-side gastrojejunostomy was performed on all horses. Two horses returned to work and survived ≥3 years. One horse was euthanased 6 months post-surgery due to recurrent abdominal pain, and one was found dead 5 months postsurgery after an unattended foaling. 相似文献

Signs of mild colic, intermittent lethargy, and weight loss of 6 weeks' duration in a 2-year-old Quarter Horse gelding were attributed to persimmon (Diospyros virginiana) phytobezoar formation. Diagnosis of the phytobezoar was facilitated by gastric endoscopy. Signs of gastrointestinal tract obstruction were associated with a large phytobezoar in the lumen of the stomach, gastric ulceration, and obstruction of the small intestine (as a consequence of fragmentation of the primary bezoar). Conservative treatment, using mineral oil and dioctyl sodium sulfosuccinate, was unsuccessful. A celiotomy was performed, and gastric impaction and partial obstruction of the small intestine associated with phytobezoar formation and fragmentation were identified. The horse made a complete recovery following removal of all phytobezoars. Persimmon phytobezoar should be considered in the fall and winter as a possible cause of lethargy, colic, and weight loss in horses allowed access to persimmon fruit. 相似文献

A 2-month-old Warmblood colt presented with recurrent colic and regurgitation. Gastroscopy, performed on several occasions, and barium-contrast radiography revealed severe squamous gastric ulceration and stenosis at the level of the margo plicatus. Treatment with omeprazole reduced the extent and severity of the gastric ulcers but did not affect the stenosis. The foal was euthanised because of a poor prognosis, and post-mortem examination confirmed the clinical diagnosis. Severe squamous gastric ulceration, granulation tissue formation and cicatrisation of deep gastric lesions were considered to have caused the stenosis. Gastroduodenal outflow obstruction is a recognised disorder in foals, but stenosis at the level of the margo plicatus has not been reported in foals or adult horses. To the authors' knowledge, this is the first case of severe squamous gastric ulceration, complicated by stenosis at the level of the margo plicatus, in a foal. Although rare, gastric stenosis should be considered in foals suffering recurrent colic and regurgitation. 相似文献
