Endometriosis is an enigmatic disease, with no specific cause or trigger yet discovered. Major factors that may contribute to endometriosis in the pelvic region include environmental, epigenetic, and inflammatory factors. Most experts believe that the primary mechanism behind the formation of endometrial lesions is associated with Sampson's theory of "retrograde menstruation". This theory suggests that endometrial cells flow backward into the peritoneal cavity, leading to the development of endometrial lesions. Since this specific mechanism is also observed in healthy women, additional factors may be associated with the formation of endometrial lesions. Current treatment options primarily consist of medical or surgical therapies. To date, none of the available medical therapies have proven effective in curing the disorder, and symptoms tend to recur once medications are discontinued. Therefore, there is a need to explore and develop novel biomedical targets aimed at the cellular and molecular mechanisms responsible for endometriosis growth. This article discusses a recent molecular pathophysiology associated with the formation and progression of endometriosis. Furthermore, the article summarizes the most current medications and surgical strategies currently under investigation for the treatment of endometriosis. [ABSTRACT FROM AUTHOR]

Introduction: Due to the constantly growing demand for surgical treatment of obesity, it is necessary to create new bariatric centers and further improve presently active ones., Aim: To identify which stages of conducting peri-operative care and organizing a modern bariatric center currently pose the greatest challenge., Material and Methods: An anonymous survey was designed and distributed to bariatric surgeons. Our questionnaire was divided into three parts: demographic characteristics, difficulties associated with peri-operative care for bariatric patients (assessed on a scale of 1-5) and difficulties associated with organization or running of bariatric centers in which participants are currently working (assessed on a scale of 1-5)., Results: Overall, 70 surgeons and surgical residents from 17 surgical centers participated in our survey. The most difficult element of the pre-operative care was compliance with the recommendation to cease smoking (3.47 ±1.28). The most difficult obstacle during the postoperative care period was implementation of the enhanced recovery after surgery (ERAS) protocol (2.27 ±1.31). Funding for the bariatric treatment was obtained exclusively from the National Health Fund by 60 (85.7%) respondents working in 15 different bariatric centers (88.2%). Among elements of bariatric infrastructure access to operating theater equipment sized for morbidly obese patients was reported to be the most difficult (3.8 ±1.68)., Conclusions: Pre-operative recommendations including smoking, physical activity or weight loss, as well as introducing ERAS protocol based peri-operative care, are difficult to execute in bariatric departments. Future specialized bariatric centers should be included in the centralized register and equipped with specialized infrastructure for morbidly obese patients., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2019 Fundacja Videochirurgii.)
