Intraoperative Biopsy and Microscopy During Exploratory Laparotomies     

E. A. STONE D.V.M.  C. A. RAWLINGS D.V.M.  PH.D.  † &#;  K. W. PRASSE D.V.M.  PH.D.  ‡ J. R. DUNCAN D.V.M.  PH.D.  § 《Veterinary surgery : VS》1978,7(4):93-96

Intraoperative biopsy and microscopy were evaluated, retrospectively, in 23 exploratory laparotomies. After comparing the surgical impression to the microscopic diagnosis obtained during surgery, the use of intraoperative cytologic and frozen section examination altered the surgical plan in 13 cases and reinforced the surgical plan in 10 cases. No cases had an intraoperative microscopic diagnosis that differed from the postoperative histologic examination of paraffin sections. Recommendations for selecting cases and for using intraoperative biopsy and microscopy are included.  相似文献

Extract

In order to utilize spring growth efficiently under a system of grassland farming, a New Zealand dairy farmer endeavours to calve as many cows as possible within a four to six weeks' period. To maintain this calving pattern, herd members must conceive by 70 to 80 days after calving. Consequently normal postparturient uterine involution, together with a minimum of delay in the onset of ovarian activity and oestral cyclicity, is of vital importance. A study of these phenomena may be very rewarding in helping to achieve optimal reproductive efficiency.  相似文献

Sir,—A 7-month-old lamb was presented for slaughter, one of a line of 460. The animal was in good condition and, except for a moderately enlarged abdomen, no abnormalities could be detected on ante-mortem examination.  相似文献   

Computed tomographic assessment of vascular invasion and resectability of mediastinal masses in dogs and a cat     

WE Scherrer  AE Kyles  VF Samii  EM Hardie  PH Kass  CR Gregory 《New Zealand veterinary journal》2013,61(6):330-333

AIMS: To assess the sensitivity of non-angiographic contrast-enhanced computed tomography (CT) to determine the presence of vascular invasion of cranial mediastinal masses in dogs and a cat, and to evaluate the association between vascular invasion and peri-operative mortality.

METHODS: A retrospective study was conducted on 25 dogs and one cat. CT scans were completed with slices ranging from 2 to 10 mm. CT images were evaluated by a board-certifi ed radiologist blinded to previous diagnoses and surgical fi ndings. Each CT study was evaluated for vascular invasion, defi ned as disruption of the vessel wall and extension of the mass into the vessel lumen. Data retrieved from the surgery reports included surgical approach, whether vascular invasion was present, the surgeon's decision on operability, and post-operative complications.

RESULTS: Computed tomographic evaluation revealed 25/26 masses had no evidence of vascular invasion. During surgical exploration, 10/26 masses were found to invade major regional vasculature; the cranial vena cava (CVC) was the vessel most commonly invaded (7/10 animals), and 4/7 (57%) patients with invasion of the CVC were euthanised or died in the perioperative period, from surgical or disease-related problems, which was signifi cantly higher than patients without vascular invasion (p=0.045).

CONCLUSIONS: Non-angiographic contrast-enhanced CT was signifi cantly less sensitive for detecting vascular invasion of cranial mediastinal masses when compared with surgical evaluation. If the CVC was invaded by a tumour there was a signifi cant risk of death peri-operatively when compared with non-invasive cases.

CLINICAL RELEVANCE: Due to the signifi cantly higher mortality risk associated with invasion of the CVC, a more sensitive method than CT should be investigated to determine vascular invasion of mediastinal masses pre-operatively.  相似文献

The New Zealand material was supplied between 1957 and 1960, by Dr J. D. Manning, then of the National Health Institute, Wellington.  相似文献
