Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1) Number of times of electrocoagulation during surgery 2) Cumulative time of electrocoagulation during surgery The following items will be evaluated in the PureStat- and non-use groups, as well as by site of bleeding in all patients. The number of ovarian bleeding sites, the number of ovarian bleeding sites that stopped spontaneously without hemostatic treatment, the number of ovarian bleeding sites that required hemostatic treatment, and the number of bleeding sites and hemostatic sites for each side of the ovary will be counted. For each ovarian bleeding site, the number of times of electrocoagulation, cumulative time of electrocoagulation, amount of PureStat used, hemostatic method, and the nature of bleeding (arterial or venous) are evaluated. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1) Postoperative change in serum AMH level (percentage decrease from preoperative value) 2) Peritoneal bleeding at the site of detachment of peri-ovarian adhesions associated with ovarian cyst removal: Count the number of bleeding sites, the number of sites where the bleeding stopped spontaneously without hemostatic treatment, and the number of peritoneal bleeding sites that required hemostatic treatment. For each site of peritoneal bleeding due to detachment of peri-ovarian adhesions associated with ovarian cyst removal, the number of times of electrocoagulation, cumulative time of electrocoagulation, amount of PureStat used, hemostatic method, and nature of bleeding (arterial or venous) will be evaluated. 3) Achievement rate of hemostasis with PureStat alone (number of bleeding sites hemostatic with PureStat alone/venous number of bleeding sites) 4) Rebleeding rate after achieving hemostasis with PureStat alone (number of rebleeding sites/number of venous bleeding sites hemostatically stopped with PureStat alone) 5) Amount of PureStat used per case 6) Douglas fossa echo free space | — |
