Item Unilateral and bilateral laparoscopic ovariectomy in 157 mares: A retrospective multicenter study(Wiley, 2011-12) Roecken, Michael; Mosel, Gesine; Litzke, F.; Verver, Jorrit; Rijkenhuizen, Astrid B. M.; Seyrek-İntaş, Deniz; Seyrek-İntaş, Kamil; Uludağ Üniversitesi/Veterinerlik Fakültesi/Kadın Hastalıkları ve Doğum Anabilim Dalı.; AAH-7292-2019; 6506990178; 6603409870Objective: To evaluate surgical techniques, perioperative complications and outcome of laparoscopic surgery for unilateral and bilateral ovariectomy in mares. Study Design: Retrospective multicenter case series. Animals: Mares (n = 157). Methods: Indications for surgery were neutering, fertility problems, elimination of hormone-related abnormal behavior, ovarian tumors as well as nonregressive ovarian hematomas or cysts. Ovariectomy (n = 206) were performed by a standard laparoscopic procedure in 157 standing sedated mares. Dissection and hemostasis were achieved by using either (1) a linear stapling device, (2) bipolar electrosurgical instruments, with or without a modified Roeder knot, (3) a vessel-sealing system, or (4) a diode-laser with ligation. For some larger ovarian masses (>20cm diameter), a 2-step surgical procedure was used with standing flank laparoscopic ovariectomy followed by ovarian retrieval through a median celiotomy. Surgical techniques, outcome, and perioperative complications of each method were recorded and analyzed. Results: Laparoscopic dissection of the ovary was accomplished in all mares. Because of the size of the ovarian tumor (n = 7) or in 1 mare with behavioral problems (n = 1), the dissected ovary was removed through a median celiotomy under general anesthesia. Seventeen mares (10.8%) developed postoperative complications (eg, incisional drainage, incisional infection, seroma formation, dehiscence, transient fever and mild abdominal discomfort). All mares with flank incisional problems had ovarian size >12 cm and in 15 (88%) of these mares electrosurgical instruments were used for mesovarial dissection. Conclusions: Laparoscopic ovariectomy in standing sedated mares provides good surgical access and is associated with low morbidity.Item Untersuchungen zur subarachnoidalen thorakolumbalen Anästhesie mit Detomidin beim Pferd(Hippiatrika Verlag, 2001) Roecken, Michael; Kırmızıgül, Ali Haydar; Cihan, M.; İntaş, Deniz Seyrek; Topal, Ayşe; İntaş, Kamil Seyrek; Uludağ Üniversitesi/Veteriner Fakültesi.; 6506990178; 9740699300; 6603409870In this study the effect of subarachnoid applicated Detomidine and local infiltration anaesthesia in the flank for laparoscopic ovariectomy was compared in 20 Turkish native mores. In a total of seven mores (group 1) 30 mug/kg and 40 mug/kg Detomidine was administered by a catheter, pieced with a Huber point Touhy cannula through the lumbosacral space, and pushed forward to the thoraco-lumbar region. The other 13 mores (group 2-control) were sedated and then infiltration anaesthesia in the flank was performed with 20-30 ml 2 % Mepivacain. In both groups physiologic parameters and blood values were measured before and during anaesthesia (15, 30, 45, 60, 75, 90, 120 and 150 minutes). The results of this study showed that a dose of 30 mug/kg subarachnoid applied Detomidine induces no anaesthesia and that a dose of 40 mug/kg has a certain anaesthetic effect but is not sufficient for a surgical intervention. The anaesthetic effect of locally infiltrated Mepivacain in the region of incision and in the suspensory ligaments of the ovaries is sufficient to remove the ovaries and no pain during operation was observed.
