Billroth I technique application after resection of gastric leiomyoma in a dog

Background: Gastric neoplasia is rare, corresponding to less than 1% of cases, with a lower prevalence of those involving smooth muscle tissues. In these cases, clinical signs worsen in the occurrence of pyloric obstruction, leading to clinical manifestations such as chronic emesis. The exeresis of the neoplasm is promoted as a therapeutic measure to reestablish gastrointestinal flow. There partial gastrectomy followed by gastroduodenal anastomosis, using the Billroth I technique, is among the available surgical techniques. The therapeutic success of the Billroth I technique after pylorectomy was reported in a dog with gastric leiomyoma. Case: A 9-year-old male Poodle dog, weighing 9.5 kg, was referred for clinical evaluation with a history of chronic vomiting starting three months ago, progressive weight loss, and melena, previously treated by another Veterinarian as idiopathic gastroenteritis. The physical evaluation of the animal showed a state of normal consciousness, body score 4/9, pale ocular and oral mucous membranes, respiratory rate 20 mpm, heart rate 166 bpm, a rectal temperature of 37.9°C, and dehydration degree of 8.0%. Blood count showed normocytic normochromic anemia and leukocytosis with shift to the right. Radiographic and endoscopic examinations were not noteworthy. Endoscopic biopsy after a histopathological evaluation showed no cellular or tissue atypia. On the other hand, abdominal ultrasound assessment revealed thickening with loss of echotexture and definition of the muscular layer of the gastric wall, pyloric and duodenum region compatible with benign antral muscle hypertrophy and/or pyloric neoplasia. The animal worsened 5 days after the initial treatment, with progressive episodes of emesis and melena, opting for an exploratory laparotomy. A mass of firm consistency measuring approximately 2.5 × 6.0 cm in diameter was found in the pyloric region, opting for a pylorectomy. The excised fragment was sent for histopathological...

Pylorectomy and gastroduodenostomy (Billroth I procedure) for obstructive antrum pyloric leiomyoma in a bitch

Background: Gastric neoplasms are uncommon in dogs, especially those affecting smooth muscle layers. Leiomyoma is a smooth muscle benign neoplasm, which requires surgical resection. Pylorectomy and gastroduodenostomy (Billroth I procedure) is the most indicated technique in cases not affecting the biliary and pancreatic tracts. Thus, the purpose of this study was to report a successful case of Billroth I procedure in a bitch presenting antrum pyloric obstructive leiomyoma. Case: A 12-year-old, non-spayed, Cocker Spaniel bitch was admitted presenting depression, hyporexia, postprandial vomiting and sparse episodes of hematemesis, for 30 days. Clinical suspicion on obstructive gastric outflow disease was established. Bloodwork (complete blood count, BUN, albumin, ALP and ALT), abdominal ultrasound and thoracic radiographs were assessed. The patient undergone upper gastrointestinal endoscopy. On endoscopic evaluation, small hemorrhagic mucosa ulcers were visualized on the gastric body, antrum and pylorus. Moreover, a sessile, ulcerated, round-shape and infiltrated antral-pyloric mass was seen. The mass was 1.5-2.0 cm in diameter and apparently involved the smooth muscle layer, causing severe pyloric obstruction. However, endoscopic evaluation of the duodenum was possible. Several biopsy samples were taken from the neoplasm and sent for histopathologic assessment. The result was [...](AU)

Aspectos clínicos, cirúrgicos, histológicos e pós-operatórios de oito cadelas com leiomioma vaginal / Clinical, surgical, histological and postoperative aspects in the case of eight bitches with vaginal leiomyoma

O presente trabalho reporta as características clínicas e cirúrgicas de oito casos de cadelas portadoras de leiomioma vaginal, com histórico de aumento de volume na região perineal, aparecimento de massa pela vulva, disquezia, tenesmo e disúria. As pacientes foram submetidas à cirurgia de episiotomia para ressecção da massa neoplásica, e em quatro casos foi necessária a ovariossalpingo-histerectomia. Porém, uma delas apresentou recidiva, e, no segundo procedimento cirúrgico de exérese de neoformação, o histopatológico diagnosticou leiomiossarcoma. A paciente ainda apresentou mais duas recidivas, até o proprietário optar pela eutanásia. Decorridos quatro meses, as sete cadelas diagnosticadas com leiomioma não apresentaram recidiva, e os proprietários relataram ausência de sinais relacionados com a doença descrita. Conclui-se que a episiotomia para ressecção da massa vaginal e a ovariossalpingo-histerectomia nas cadelas inteiras nos casos de tumores vaginais benignos são tratamentos satisfatórios, com bom prognóstico, ao contrário do leiomiossarcoma.(AU)

This study reports the clinical and surgical procedures of eight cases of bitches with vaginal leiomyoma. All animals presented increased volume in the perineal region, and exteriorization of the vulva, dyschezia, tenesmus and dysuria. The patients underwent episiotomy surgery for resection of the neoplastic mass, and ovariosalpingohisterectomy in four cases. However, one had recurrence on the second surgical procedure for removal of neoformation, histopathological diagnosed leiomyosarcoma, the patient also had two more relapses, until the owner chose euthanasia. After four months, the seven dogs diagnosed with leiomyoma showed no recurrence and the owners reported no signs of the disease described. We concluded that episiotomy for vaginal mass resection combined with ovariohysterectomy in cases of benign vaginal tumors have shown satisfactory treatment with good prognostic.(AU)

Esofagectomia torácica parcial no tratamento de leiomioma em esfíncter esofágico inferior de cão / Partial thoracic esophagectomy in the treatment of leiomyoma in the lower / esophagealsphincter of dogs

Tumores esofágicos em cães são raros e dentre estes, o leiomioma é o mais relatado. Os sinais clínicos mais comuns são disfagia, regurgitação e emaciação. Foi atendido no Hospital de Clínicas Veterinárias (HCV) da Universidade Federal do Rio Grande do Sul (UFRGS) um cão da raça Dálmata, macho, oito anos, apresentando sialorreia, regurgitação, vômito, algia abdominal e emaciação. No exame endoscópico visibilizou-se massa tumoral próxima ao esfíncter esofágico inferior e fundo gástrico, e foram coletadas amostras para análise histopatológica, obtendo-se resultado compatível com leiomioma esofágico e hiperplasia gástrica. Realizou-se ressecção esofágica e anastomose esôfago-gástrica. Decorridos três dias de pós-operatório o animal foi a óbito. Na necropsia não foram observadas alterações macroscopicamente significativas e microscopicamente sugeriu-se insuficiência renal. Este relato tem o objetivo de apresentar um caso de leiomioma em esfíncter esofágico inferior em um cão, no qual a terapêutica adotada foi a exerese tumoral por toracotomia.

Esophageal tumors are rare in dogs, among these, leiomyoma is the most reported. The most common clinical signs are dysphagia, regurgitation and emaciation. An 8-year-old, Dalmatian male dog was referred to the Hospital de Clínicas Veterinárias (HCV), Universidade Federal do Rio Grande do Sul (UFRGS) presenting drooling, regurgitation, vomiting, abdominal pain and emaciation. Endoscopic examination revealed a growth near the lower esophageal sphincter and gastricfundus, and samples were collected for histopathological examination. The results were consistent with esophageal leiomyoma and gastric hyperplasia. Esophageal resection and esophageal-gastric anastomosis was conducted. Three days post-operative the animal died. At necropsy no changes were observed macroscopically, and microscopically significant renal insufficiency was suggested. This report aims at presenting a case of leiomyoma at lower esophageal sphincter in a dog, in which the adopted therapy was tumor exeresis by thoracotomy.
