Utility of a minimal skin incision technique for abdominal hysterectomy at a regional core hospital: a retrospective study

BACKGROUND: We present a minimal skin wound abdominal hysterectomy for patients with leiomyomas and describe the characteristics of this technique. The skin wound was made as small as possible, with a maximum length of 6 cm. METHODS: In addition to introducing minimal skin wound abdominal hysterectomy, we retrospectively analyzed the medical records of 82 patients treated with minimal skin wound abdominal hysterectomy exclusively by two experts at Maruyama Memorial General Hospital between January 2013 and December 2016. Relationships between the leiomyoma characteristics and the difficulty of this operation, as estimated by operation time and blood loss, were statistically investigated. RESULTS: First, we introduce a case in which we performed minimal skin wound abdominal hysterectomy on a 46-year-old Japanese patient with multiple leiomyomas (maximum 8 cm in diameter). Then, we assessed the impacts of the leiomyoma characteristics on the difficulty of this operation. On multivariate analysis, the number of leiomyomas significantly affected operation difficulty. Other characteristics of the target leiomyoma showed no effect. Additionally, higher body mass index also made the operation more difficult. CONCLUSIONS: Although multiple leiomyomas can make this procedure difficult, minimal skin wound abdominal hysterectomy is safe and effective for use in many cases.
