Perspectives in adhesion prevention in gynaecological surgery.

Adhesions are a frequent, clinically relevant, and often costly complication of surgery that can develop in any body location regardless of the type of surgical procedure. Adhesions result from surgical trauma inducing inflammatory and coagulation processes and to date cannot be entirely prevented. However, the extent of adhesion formation can be reduced by using good surgical technique and the use of anti-inflammatory drugs, haemostats, and barrier agents. Strategies are needed in the short-, medium- and longer-term to improve the prevention of adhesions. In the short-term, efforts are needed to increase the awareness amongst surgeons and patients about the potential risks and burden of surgically induced adhesions. To aid this in the medium- term, a risk score to identify patients at high risk of adhesion formation is being developed and validated. Furthermore, available potentially preventive measures need to be highlighted. Both clinical and health economic evaluations need to be undertaken to support the broad adoption of such measures. In the longer- term, a greater understanding of the pathogenic processes leading to the formation of adhesions is needed to help identify effective, future treatments to reliably prevent adhesions from forming and lyse existing ones.

Total surgical time in laparoscopic supracervical hysterectomy with laparoscopic in-bag-morcellation compared to laparoscopic supracervical hysterectomy with uncontained morcellation.

Background: A possible solution to the problem of cell dissemination through laparoscopic uncontained morcellation during laparoscopic supracervical hysterectomy (LASH) is the use of laparoscopic in-bag morcellation. One criticism regarding the use of in-bag morcellation is the additional surgical time associated with this procedure. Objectives: In this retrospective study we compared the total surgical time in LASH with laparoscopic in-bag morcellation (107 cases from 2016-2018) and LASH with uncontained morcellation (47 cases from 2015-2017). Materials and Methods: All surgeries were performed in the same department of minimally invasive gynaecological surgery by a total of three experienced surgeons for the indication of bleeding disorder and / or dysmenorrhea. Main outcome measure: We measured and compared total surgical time, surgical outcome, blood loss and complications in LASH with in-bag morcellation and with uncontained morcellation. Results: Total surgical time in both procedures do not show a significant difference. Considering the learning curve in laparoscopic bag use, the total surgical time in LASH with laparoscopic in-bag morcellation is shorter than total surgical time in LASH with uncontained morcellation. Laparoscopic in-bag morcellation consumes time for bag use and handling, but saves time as it eliminates the need for meticulous sampling of lost tissue fragments and the complex lavage of the peritoneal cavity after morcellation. There is no difference between both groups in terms of blood loss, complications and surgical results. Conclusion / What is new?: We conclude that LASH with in-bag morcellation is not related to additional surgical time when compared to LASH with uncontained morcellation.

Extravascular Dispersion of Polyvinyl Alcohol Microsphere Particles in Uterine Artery Embolization.

Uterine artery embolization (UAE) is a common minimally invasive treatment of different uterine pathologies, such as fibroids, adenomyosis, and menorrhagia. The procedure involves the injection of embolic agents into the uterine arteries, whereby various particles can be used, such as polyvinyl alcohol (PVA). Complication of UAE is the dispersion of polyvinyl alcohol (PVA) microsphere particles in the uterine body which can lead to a granular vaginal discharge. We report the management of complications of PVA microspheres dispersed from the uterine body causing postprocedural discomfort due to the vaginal passage of microspheres or because of an induced fibroid-size enlargement. The dispersion of the PVA microspheres is one example of a minor UAE complication, which nevertheless causes significant distress to the patient and eventfully requires further surgical interventions.

Adhesions and Anti-Adhesion Systems Highlights.

The peritoneal and intrauterine cavities are lined by fragile membranes with a high-wound healing capacity, e.g. repairing the endometrium in its cyclical "injury and scar-free repair process" during menstruation. However, peritoneal and intrauterine fibrosis and adhesions can develop after surgical trauma through activation of molecular, immune and genetic mechanisms. During procedures with a high-risk of adhesions, the use of new peritoneal and intrauterine conditions in combination with anti-adhesion substances are promising measures to preserve peritoneal and endometrial function and avoid the most common complication of gynecological surgery. Highlights of adhesions and anti-adhesion prevention techniques in laparoscopic, laparotomic and hysteroscopic surgeries are discussed in this paper. Unfortunately, evidence is lacking to prove the superiority of one technique over its counterparts in terms of postoperative adhesions, such as instrumentation, type of energy, distending media, and intracavitary pressure. Additionally, there is limited evidence about the efficacy and outcomes of techniques and adjuvant measures used during adhesiolysis. The definition of a universal intrauterine adhesions classification scheme as well as a prognostic scoring system to identify women at high risk of postoperative adhesions are necessary for advising those who could benefit the most of the use of antiadhesion barriers.

The cost-effective, but forgotten, medical endometriosis therapy: a prospective, quasi-randomized study on progestin therapy.

Endometriosis represents nowadays a real burden for the patients as well as for the physicians, as it requires surgical and/or medical treatment, often long - termed and repeated. Moreover, the high costs necessary to diagnose and treat endometriosis represent a real economic burden, being comparable to other chronic diseases like diabetes or rheumatoid arthritis. Therefore, the physicians dealing with this disease should take into account not only the efficacy of the treatment, but also the economic aspects and patients compliance. The present paper analyses the efficiency of progestins (lynestrenol and medrogestone) in endometriosis as a cost - effective, but forgotten medical therapy of the disease. Our study underlines the good tolerability of progestins, as they have limited side effects, the compliance of patients being high. They are also low-cost medications, which could represent an effective alternative method in the endometriosis treatment, especially in less - developed countries that cannot afford the higher therapeutic costs.
