Absorbable Hemostatic Particles to Reduce the Damage on the Follicular Reserve After Ovarian Endometriomas Stripping

Objective: to reduce the surgical damage to the ovarian reserve, after stripping of ovarian endometrioma, of the necrotic type given by the electrohaemostasis or ischemic type given by the suture. Design: perform haemostasis on ovarian parenchyma with topical haemostatic agents. Materials and methods: we used Arista AH which is a powder made up of microporous polysaccharide hemospheres that act by osmotic action and accelerate the natural coagulation process. We used Arista AH in 27 women with mono- or bilateral ovarian endometriosis. Results: in all treated cases we obtained a rapid and optimal haemostasis. There were no post-surgical complications related to haemostatic defects. Three months after the surgery, we checked the Antral Follicle Count (AFC) with a trans-vaginal ultrasound probe. AFC in 24 women with full follow-up gave the following results: unilateral endometrioma – AFC between 5 and 8 (MV: 6.3), bilateral endometriomas – the AFC between 5 and 7 (MV: 5.8). Conclusions: The use of Arista AH powder allows highly effective hemostasis and is easy to use, fully respecting the residual ovarian parenchyma after stripping.

O28 APPLICATION OF MICROPOROUS POLYSACCHARIDE HEMOSPHERES DURING TRANSVERSUS ABDOMINAL RELEASE TO REDUCE SEROMAS AND HEMATOMAS

Aim Wound complications, like seromas and hematomas, occur in 23% after transversus abdominis release (TAR). Hemostat agents like fibrin glue have potential to reduce this rate, by vessel sealing and tissue bonding. But these are expensive. A topical hemostatic, like microporous polysaccharide hemospheres (MPH), is much cheaper, but its potential to reduce seromas and hematomas has never been analyzed in ventral hernia surgery. Material and Methods After the first 25 consecutive TAR patients (Control group, 2016-2018), MPH was introduced as an adjunct in a consecutive group of 25 TAR patients (Intervention group, 2019-2020). MPH was sprinkled in the TAR planes and subcutaneous tissue. Groups were compared. Results Pre-operative base-line characteristics and the overall complexity of the hernia patients and operations did not differ between the two groups. Postoperatively, the overall rate of surgical site occurrences (SSO) differed (CG:60%;IG:32%), but not significantly. Seromas (CG:5%;IG: 3%) and hematomas (CG:28%;IG:8%) did not differ significantly between the two groups. Medical complications (CG:13%;IG:10%) and two-year recurrence rate (CG:12%;IG:16%) also did not differ. Conclusions This study did not demonstrate a clear effect of MPH on the incidence of SSO, seromas or hematomas after a transversus abdominis release, despite the high incidence of wound complications in the first group of TAR patients (presumably, reflecting the learning curve of TAR). The fact that MPH does not glue tissue layers and minimize dead space, may be causative. MPH is not advised as an adjunct to reduce SSO.
