OBJECTIVE To describe a minimally invasive 3-portal laparoscopic approach for elective ovariohysterectomy and the outcome of that procedure in a population of goats.
DESIGN Descriptive clinical study.
ANIMALS 16 healthy client-owned goats.
PROCEDURES Food but not water was withheld from all goats for 24 hours before the procedure. Goats were anesthetized and positioned in dorsal recumbency. Three laparoscopic portals were created in the caudoventral portion of the abdomen, and the abdomen was insufflated to a maximum pressure of 10 mm Hg. A blunt-tip vessel sealer and divider device was used to transect the left and right mesovarium and mesometrium and uterus, and the resected tissue was removed from the abdomen. After hemostasis was verified, the portals were closed in a routine manner and anesthesia was discontinued. Goats were discharged from the hospital 24 hours after the procedure, and owners were contacted by telephone or email to obtain short- and long-term follow-up information by use of standardized questions.
RESULTS All procedures were performed by a surgeon and assistant surgeon. The procedure was not complex and was easily learned. No intraoperative complications were reported, and only 1 goat required rescue analgesia post-operatively. No other postoperative complications were recorded. Median surgery time was 43 minutes (range, 20 to 65 minutes). All owners were satisfied with the outcome of the procedure, and several perceived that the procedure improved goat behavior.
CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that laparoscopic ovariohysterectomy was a viable alternative for elective sterilization of female goats.
Case Description—A 4-month-old Hampshire ram underwent open right inguinal herniorrhaphy and unilateral castration following herniation that developed after a kick injury. Seven months later, the ram was reevaluated because of scrotal swelling of 1 month's duration as well as suspected left inguinal hernia.
Clinical Findings—The ram had marked scrotal swelling. Palpation of the left testicle revealed no abnormalities. Ultrasonographic examination revealed heterogenous tissue within the cranial and medial portions of the scrotum with pronounced accumulation of hypoechoic fluid at the scrotal apex. Examination findings indicated left-sided indirect inguinal herniation of omentum.
Treatment and Outcome—To preserve fertility, left inguinal hernioplasty without castration was performed. The ram was anesthetized and placed in dorsal recumbency, and laparoscopic abdominal evaluation revealed omental entrapment within the left inguinal ring. The omentum was removed, and a polypropylene mesh was secured over the internal inguinal ring with an articulating hernia stapler. Following mesh placement, a dorsally based peritoneal flap was elevated and secured over the mesh repair. The ram recovered well from surgery; there was no repeated herniation following the surgical correction, and the ram was able to breed successfully without complication.
Clinical Relevance—Laparoscopic mesh hernioplasty can be successful in rams with inguinal hernias when preservation of fertility is preferred.
To assess signalment, clinical findings, and treatments for New World camelids (NWCs) hospitalized for evaluation and treatment of neonatal disorders and investigate associations between these factors and death during and after hospitalization.
267 NWCs ≤ 30 days of age.
Medical records of a veterinary teaching hospital were retrospectively reviewed to identify NWCs admitted for evaluation and treatment of neonatal disorders between 2000 and 2010. Signalment, physical examination data, diagnostic findings, treatments, and outcomes were recorded. Factors were examined for association with death during hospitalization and the overall hazard of death by use of multivariable logistic regression and Cox proportional hazards analysis, respectively.
The sample comprised alpacas (n = 255) and llamas (12). Median age at admission was 3 days, and median hospitalization time was 2 days; 208 of the 267 (77.9%) neonatal NWCs survived to hospital discharge. Factors associated with increased odds of death during hospitalization included prematurity or dysmaturity, hypothermia, sepsis, toxic changes in neutrophils, and undergoing surgery. The odds of death during hospitalization also increased as anion gap increased. After discharge, 151 of 176 (85.8%) animals had follow-up information available (median follow-up time, 2,932 days); 126 (83%) were alive and 25 (17%) had died. Prematurity or dysmaturity, congenital defects, sepsis, oxygen administration, and undergoing surgery as a neonate were associated with an increased hazard of death; the hazard of death also increased as serum chloride concentration at the time of hospitalization increased.
CONCLUSIONS AND CLINICAL RELEVANCE
Results suggested the prognosis for survival during and after hospitalization is good for most NWCs hospitalized because of neonatal disorders.
