title: Temporarily Blocking the Uterine Artery to Dig Out a Diffused Adenomyosis Lesion Treated Laparoscopically.
abstract: To show the tips and tricks of a simpler technique for temporary blocking of the uterine artery in laparoscopic resection of a diffuse adenomyosis lesion to make the procedure more efficient and reproducible.
  
  
  
  This study is designed to be a step-by-step explanation of the technique using videos and pictures (Canadian Task Force classification III).

  Three patients (age 39-42 years, 41±1.73) were diagnosed with diffuse adenomyosis with severe secondary dysmenorrhea willing to reserve the uterus and a poor response to medical management. Gynecologic examination revealed that the uteri sizes were 9 to 14 weeks. Transvaginal ultrasonography revealed that the lesions were 4 to 7 cm in size.
  
  
  
  Laparoscopic resection of the diffuse adenomyosis lesion was conducted after temporary blocking of the uterine artery with a rubber belt.
  
  
  
  The traditional methods for injecting diluted vasopressin in the myometrium around the affected area and a half-life period of 30 minutes were used. Many adenomyosis patients with severe dysmenorrhea and menometrorrhagia have a large lesion; thus, the operating time is longer. The maximum dose of vasopressin is 20 units daily, and hypertensive patients have a contraindication. We made an incision of the broad ligament of the avascular area near the uterine artery and pulled the rubber pressure pulse ligation tightly through to temporarily block the uterine artery without vasopressin completely through the laparoscopic resection of the diffuse adenomyosis lesion. Intraoperative blood loss was only 120 to 230 mL. In this video, we show a simpler technique for temporarily blocking the uterine artery in laparoscopic resection of diffuse adenomyosis with a stepwise expiation. A levonorgestrel-releasing intrauterine system (Mirena; Bayer, Leverkusen, Germany) was placed in the uterus from the vagina immediately after surgery. At the 3-25 month (10.67±12.42) follow-up, visual analog scale scores were obviously reduced, and the menstrual quantity and amenorrhea dramatically declined after the surgery. All patients had no recurrence and no Mirena loss as assessed by vaginal ultrasound and the visual analog scale [1]. Estrogen was maintained at the normal level after 3 months. This study was approved by the Institutional Review Board of the Changzhou Maternal and Child Health Hospital Affiliated to Nanjing Medical University.
  
  
  
  The incidence of adenomyosis is a newer trend that is being used in patients with a poor response to medical management of uterine lesions and large lesions in China. Using the rubber belt to temporarily block the uterine artery in laparoscopic resection of the diffuse adenomyosis lesion offers the possibility of the rubber belt being effective, safe, and reproducible. Minimally invasive surgery in expert hands is the preferred solution of an increasing number of patients after drug treatment failure.
