Summary

Seprafilm is an FDA-approved temporary bioresorbable barrier that physically separates opposing tissue surfaces. The physical presence of the membrane separates adhesiogenic tissue while the normal tissue repair process takes place. When used in the abdominopelvic cavity, it has been shown to reduce the incidence of adhesions. The intrauterine cavity is a potential space where the walls of the uterus are collapsed upon itself in the normal state. It has been demonstrated that the trauma of removing a submucosal fibroid with electrocautery exposes the uterus to great potential for intrauterine adhesions since the raw charred surface is directly opposed to the opposite endometrial surface. Previous studies have shown that the placement of hyaluronic acid in the intrauterine cavity after a myomectomy is not only safe, but also decreases the incidence of intrauterine adhesions. The investigators hypothesize that by placing a slurry of Seprafilm in the intrauterine cavity and creating a temporary physical barrier between the walls of the uterus, that they will be able to prevent iatrogenic intrauterine adhesions. Given that approximately 24 to 48 hours after placement, the membrane becomes a hydrated gel that is slowly resorbed within one week, the investigators anticipate that the patient will have minimal to no discomfort; since no physical device is being left in the endometrial cavity, the uterus will not be contracting more than it does in its normal postoperative state.

Detailed description

The investigators will conduct a randomized controlled trial (RCT) involving patients at NewYork Presbyterian Hospital-Columbia University Medical Center and Weill Medical College of Cornell University. The investigators will enroll 328 pre- menopausal patients (\>18years) with documented submucosal myomas undergoing hysteroscopic myomectomy with monopolar resection in this study. The investigators anticipate that approximately 30% of the patients undergoing myomectomy will form intrauterine adhesions and that administration of the Seprafilm slurry will reduce the incidence to approximately 15%. Patients will be queried on post-operative days 1, 7, and 30 for pain/discomfort and the degree of intrauterine adhesions will be assessed after the patient's second menses (75-90 days post procedure).

Conditions

• Intrauterine Adhesions

Interventions

Type	Name	Description
DEVICE	Seprafilm	Seprafilm Adhesion Barrier (membrane) is a sterile, bioresorbable, translucent adhesion barrier composed of two anionic polysaccharides, sodium hyaluronate (HA) and carboxymethylcellulose (CMC). Together, these biopolymers have been chemically modified with the activating agent 1-(3-dimethylaminopropyl) -3- ethylcarbodiimide hydrochloride (EDC).
DEVICE	Sterile Saline Solution	For those randomized not to receive Seprafilm slurry, a syringe will be filled with 25ml of sterile saline.
