Surgical Time for Laparoscopic Ovariectomy in Adult and Prepubertal Dogs

Abstract

Two-portal laparoscopic ovariectomy (LOVE) was performed in adult (n=23) and prepubertal dogs (n=23) to compare surgical time and to evaluate the effect of age, body weight (BW), body condition score (BCS), ovarian pedicle fat score (OPFS) and intraoperative surgical complications on surgical time. Three classes of BCS were considered: BCS 1-2=lean; BCS 3=ideal; BCS 4-5=overweight. The same surgeon performed all surgeries. OPF was scored and was considered negative or positive. Intraoperative complications were recorded. Total surgical time was recorded from the first skin incision to the last portal closure suture placement. The surgical procedure was divided into seven stages, and each stage’s time was recorded. Data are reported as mean±SEM. Differences in the duration of defined surgical stages between groups were evaluated by age, BW, OPFS and intraoperative complications. One-way analysis of variance was used to assess the effect of BCS. No major complications were observed. Five and four minor complications were observed in adult and prepubertal dogs, respectively. Total surgical time was not different (p>0.05) between adult (20.63±0.60 min) and prepubertal (21.48±1.75 min) dogs. BCS, BW, and OPF did not affect total surgical time (p>0.05). Intraoperative complications have prolonged surgical procedure times (25.20±2.33 min vs 20.04±0.93 min). The time from the first skin incision to the insertion of the first trocar was shorter (p<0.05) in prepubertal dogs (2.38±0.12 min) compared to adult animals (2.71±0.10 min). The time needed for grasping of the right ovary was longer (p<0.05) in prepubertal dogs (3.02±0.31 vs 2.32±0.16 min) and in animals without OPF (2.94±0.24 vs 2.11±1.89 min). In conclusion, LOVE is safe in adult and prepubertal dogs with similar surgical time and complication rates.

Yetişkin ve Prepubertal Köpeklerde Laparoskopik Overiektomi Cerrahi Süresi

Abstract

Cerrahi sürenin karşılaştırılması ve yaş, vücut ağırlığı (VA), vücut kondisyon skoru (VKS), ovaryan pedikül yağ skoru (OPYS) ve intraoperatif cerrahi komplikasyonların cerrahi süre üzerine etkilerinin araştırılması amacıyla yetişkin (n=23) ve prepubertal köpeklerde (n=23) iki-portal laparoskopik ovariektomi (LOVE) yapılmıştır. Üç VKS sınıfı dikkate alınmıştır: VKS 1-2=zayıf; VKS 3=ideal; VKS 4-5=fazla kilolu. Tüm ameliyatlar aynı cerrah tarafından yapılmıştır. OPY skorlanmış ve negatif veya pozitif olarak kabul edilmiştir. İntraoperatif komplikasyonlar kaydedilmiştir. Toplam cerrahi süre, ilk deri ensizyonundan son portal kapatma sütürünün yerleştirilmesine kadar geçen süre olarak kaydedilmiştir. Cerrahi işlem 7 farklı aşamaya ayrılmış ve her aşamanın süresi kaydedilmiştir. Veriler ortalama±SEM olarak sunulmuştur. Gruplar arasında tanımlanmış cerrahi sürelere yaş, VA, OPYS ve intraoperatif komplikasyonların etkisi ile değerlendirilmiştir. VKS etkisinin değerlendirilmesi için tek yönlü varyans analizi kullanılmıştır. Majör komplikasyon ile karşılaşılmamıştır. Erişkin ve prepubertal köpeklerde sırasıyla 5 ve 4 minör komplikasyon gözlenmiştir. Erişkin (20,63±0,60 dk) ve prepubertal (21,48±1,75 dk) köpekler arasında toplam cerrahi süre farklılık göstermemiştir (p>0,05). VKS, VA ve OPY toplam cerrahi süresini etkilememiştir (p>0,05). İntraoperatif komplikasyonlar cerrahi süreyi uzatmıştır (25,20±2,33 dk; 20,04±0,93 dk). İlk deri ensizyonundan ilk trokarın yerleştirilmesine kadar geçen süre prepubertal köpeklerde (2,38±0,12 dk) erişkin hayvanlara (2,71±0,10 dk) kıyasla daha kısa olmuştur (p<0,05). Sağ ovaryumu kavramak için gereken süre prepubertal köpeklerde (3,02±0,31 dk; 2,32±0,16 dk) ve OPY negatif hayvanlarda (2,94±0,24; 2,11±1,89 dk) daha uzun olmuştur (p<0,05). Sonuç olarak LOVE, benzer cerrahi süre ve komplikasyon oranları ile yetişkin ve prepubertal köpeklerde güvenli bulunmuştur.
