Íleo paralítico em três bovinos: Relato de caso / Paralytic ileus in three cattle: case report

O íleo paralítico é uma obstrução do tipo funcional, na qual o lúmen intestinal está patente, comprometendo a passagem da ingesta no intestino. Este relato objetiva descrever três casos em vacas com aptidão leiteira, atendidos na rotina hospitalar e diagnosticados com íleo paralítico. Em seus históricos, os proprietários queixavam-se que os animais apresentavam redução do apetite, timpania ruminal, diminuição da produção de leite e eliminação das fezes. Ao exame físico, alguns sinais clínicos apresentaram destaque, como apatia, desidratação, redução da motilidade ruminal e intestinal, fezes em pequena quantidade e com muco, distensão do abdômen e ao balotamento constatou-se a presença de líquido. Na análise do fluido ruminal todos os animais apresentaram o teor de cloreto elevado (>30 mEq/L), caracterizando, dessa forma, um processo obstrutivo. Diante dos achados, suspeitou-se inicialmente de um quadro de obstrução intestinal. Nos casos, a conduta adotada foi realizar uma laparotomia exploratória através do flanco direito, porém constatou-se, que não existia qualquer segmento com obstrução de natureza mecânica, que justificasse as alterações físicas e laboratoriais encontradas. Diante destes resultados, configurou-se um quadro clínico indicativo de íleo paralítico. As vacas foram submetidas a um protocolo terapêutico pós-cirúrgico composto por antibioticoterapia, anti-inflam

Paralytic ileus is an obstruction of the functional type, in which the intestinal lumen is patent, compromising the passage of the intake in the intestine. The objective of this study was to describe three cases in dairy cows treated in the hospital routine diagnosed with paralytic ileus. In their histories, the owners complained that the animals presented reduced appetite, ruminal tympany, decreased milk yield and elimination of faeces. At the physical examination, some clinical signs were prominent in both, such as apathy, dehydration, reduction of ruminal and intestinal motility, faeces were present in small quantity and with mucus present, abdominal enlargement and the succession produced sloshing sounds. In the analysis of the ruminal fluid, the chloride content in both was high (>30 mEq/L), characterizing an obstructive process. In the face of the findings, a diagnosis of intestinal obstruction was initially suspected. In animals, the adopted approach was to perform an exploratory laparotomy through the right flank, but it was verified that there was no segment with mechanical obstruction that justified the physical and laboratorial alterations found. In view of these results, a clinical diagnosis indicative of paralytic ileus was established. The three animals were submitted to a post-surgical therapeutic protocol consisting of antibiotic therapy, anti-inflammatory, calcium, pro-kinetic and supportive treatment. The animals showed a favourable response to therapeutic treatment, with restoration of gastrointestinal function and other physiological parameters, and was discharged after a clinical evolution ranging from ten to twelve days.

As vacasforam submetidas a um protocolo terapêutico pós-cirúrgico composto por antibioticoterapia, anti-inflamatório, cálcio, procinético e tratamento de suporte. Os animais manifestaram uma resposta favorável a conduta terapêutica, com restabelecimento da função gastrointestinal e dos demais parâmetros fisiológicos, recebendo alta após uma evolução clínica variando entre dez a doze dias.

Videofluoroscopic swallow study features of lower esophageal sphincter achalasia-like syndrome in dogs.

BACKGROUND: Megaesophagus (ME) carries a poor long-term prognosis in dogs. In people, lower esophageal sphincter (LES) disorders causing functional obstruction are rare causes of ME that may respond to targeted treatment. Functional LES disorders are reported rarely in dogs because of challenges in diagnostic methodologies. HYPOTHESIS/OBJECTIVES: To identify dogs with videofluoroscopic swallow study (VFSS) features of LES achalasia-like syndrome (LES-AS). We hypothesized that dogs with LES-AS could be distinguished from normal dogs using standardized VFSS criteria. ANIMALS: Dogs with LES-AS by VFSS (n = 19), healthy normal dogs (n = 20). METHODS: Retrospective study. One-hundred thirty dogs presented to the University of Missouri Veterinary Health Center (MU-VHC) between April 2015 and December 2017 for a free-feeding VFSS; 20 healthy dogs were included as controls. Swallow studies were evaluated for failure of the LES to relax during pharyngeal swallow (LES-AS). Affected dogs subsequently were evaluated using standardized criteria to identify metrics important for identifying and characterizing dogs with LES-AS. RESULTS: Nineteen dogs with LES-AS were identified out of 130 VFSS. Megaesophagus was present in 14 of 19 (73.7%) dogs with LES-AS. A baseline esophageal fluid-line and "bird beak" were present in 68.4% (95% confidence interval [CI], 47.5%-89.3%) and 63.2% (95% CI, 41.5%-84.8%) of affected dogs, respectively. The esophagus was graded as acontractile (8/19), hypomotile (8/19), or hypermotile (3/19). CONCLUSIONS AND CLINICAL IMPORTANCE: Dogs with LES-AS may successfully be identified by VFSS using a free-feeding protocol. These data are of critical clinical importance because a subpopulation of dogs with functional LES obstruction may be candidates for targeted intervention.

Pharmacologic management of non-neurogenic functional obstruction in women.

INTRODUCTION: Impaired bladder emptying in women without neurologic disease may be related to urethral obstruction and/or impaired bladder contractility. Mechanical obstruction generally requires surgical management and options are limited for impaired bladder contractility. However, functional obstruction from voiding dysfunction or primary bladder neck obstruction may present an opportunity for pharmacologic intervention. AREAS COVERED: In this review, the authors extensively reviewed available literature regarding the use of off-label medications for functional bladder outlet obstruction in women. In addition, side effect profiles and pharmacology of these medications determined from on-label indications are reviewed. Specific medications reviewed include vaginal diazepam, baclofen, urethral botulinum toxin injection, and alpha-adrenergic blockers. EXPERT OPINION: Alpha-blockers in particular have demonstrated promise in women with demonstrable or suspected bladder outlet obstruction with side effect profiles similar to those observed in men. However, lack of quality data hinders informed decision making with alpha-blockers or any of the other agents studied in women with non-neurogenic functional outlet obstruction. In the absence of well-designed, placebo-controlled multi-institutional trials, those prescribing these medications must be aware of special considerations and side effects associated with relatively unfamiliar treatments in the context of uncertain benefit.
