Surgery is the treatment of choice for regional control of mammary neoplasms in female dogs. Various surgical techniques may be used, as long as mammary gland anatomy, lymphatic drainage, and known prognostic factors are respected. The purpose of this study was to compare surgical stress-including duration of surgery, nociception and hematological changes-and postoperative complications in dogs undergoing regional and unilateral radical mastectomy. Eighteen dogs were selected for each technique. Postoperative pain (nociception), hematological changes, and postoperative complications were compared between the two groups.
The group treated with radical mastectomy had a longer surgical duration, showed more intense physiological changes, achieved higher scores on nociception scales, and experienced more postoperative complications.
Compared to regional mastectomy, radical mastectomy was associated with longer surgical duration, greater nociceptive stimulus, greater surgical stress, and higher incidence of postoperative complications in dogs. Although evaluation of long-term results was not a goal of this study, it is suggested that postoperative recovery and patient quality of life should be considered when choosing a surgical approach for treating mammary tumors in dogs.
手术是雌性犬乳腺肿瘤区域控制的首选治疗方法。只要尊重乳腺解剖结构、淋巴引流和已知的预后因素，就可以采用各种手术技术。本研究的目的是比较接受区域和单侧根治性乳房切除术的犬的手术应激（包括手术持续时间、伤害感受和血液学变化）及术后并发症。每种技术选择18只犬。比较两组之间的术后疼痛（伤害感受）、血液学变化和术后并发症。
接受根治性乳房切除术的组手术持续时间更长，表现出更强烈的生理变化，在伤害感受量表上得分更高，且术后并发症更多。
与区域乳房切除术相比，根治性乳房切除术在犬中与更长的手术持续时间、更强的伤害性刺激、更大的手术应激和更高的术后并发症发生率相关。尽管本研究的目标不是评估长期结果，但建议在选择治疗犬乳腺肿瘤的手术方法时应考虑术后恢复和患者生活质量。
