Abstract

OBJECTIVE: To describe a motorized morcellator technique for laparoscopic removal of granulosa-theca cell tumors (GCT) in standing mares and to evaluate long-term outcome.
STUDY DESIGN: Case series.
ANIMALS: Mares (n=7) aged 4-15 years, with unilateral GCT.
METHODS: Tumor size was determined by transrectal palpation and ultrasonography. Standing sedated mares had 3 laparoscopic portal sites in the paralumbar fossa. After laparoscopic observation of the GCT, the mesovarium was desensitized, the ovarian pedicle transected with a LigaSure device, and the ovary grasped with forceps and cut in cylindrical tissue blocks using a motorized morcellator. Tissue blocks were removed through the laparoscopic sleeve. Outcome was determined by telephone interview of owners 6-40 months after surgery.

RESULTS: Estimated ultrasonographic median GCT diameter was 17 cm (range, 10-22 cm). Surgical time was 2-4.5 hours. There were no surgical complications. Two mares had mild subcutaneous emphysema at the portals after surgery. Convalescence was short, owners were satisfied with cosmetic outcome, and clinical signs associated with GCT did not recur.
CONCLUSION: The motorized morcellator allows piecemeal removal of large GCT through a relatively small laparoscopic portal. Surgical complications were rare and the cosmetic outcome is favorable.
CLINICAL RELEVANCE: A motorized morcellator is a safe and minimally invasive technique for laparoscopic removal of GCT in mares.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
