[Clinical and economic aspects of laparoscopic surgery for acute cholecystitis in delayed presentation]. / Kliniko-ekonomicheskie aspekty laparoskopicheskikh operatsii pri ostrom kholetsistite v usloviyakh pozdnei gospitalizatsii.

OBJECTIVE: To study the clinical and economic features of laparoscopic surgery for acute cholecystitis in delayed presentation. MATERIAL AND METHODS: A prospective non-randomized study (2020-2021) included 101 patients (73.2% (n=74) men and 26.8% (n=27) women, mean age 58±14.9 years) with acute cholecystitis who underwent laparoscopic cholecystectomy. Cost-effectiveness analysis of laparoscopic cholecystectomy at various periods after clinical manifestation was performed. RESULTS: Surgical treatment within 72 hours was performed in 15% (n=16) of cases (group 1), within 4-10 days - in 57.5% (n=58) (group 2), after 10 days - in 26.7% (n=27) of patients (group 3). Overall incidence of postoperative complications was 2.9%, postoperative mortality - 1.9% (two patients died from widespread peritonitis). Surgery time was 70 [65-83], 85 [69-110] and 115 [80-125] min (H=15.55, p<0.001), hospital-stay - 6 [5-7], 9 [7-10] and 11 [7-14] days, respectively (H=21.86, p<0.001). Cost of direct (medical and non-medical) treatment amounted to 29484 [27 509-33 885], 41265 [34 306-48 301] and 50591 [37 069-62 483] rubles, respectively (H=29.71, p<0.001)). CONCLUSION: Delayed hospitalization and surgical treatment of acute cholecystitis after 72 hours are accompanied by higher treatment costs by 29% in the period up to 10 days and by 58% after 10 days. These results require further validation and adjustment in large samples.

The most valuable predictorsof endometrial receptivity.

OBJECTIVE: To investigate the predictive factors of insufficient endometrial quality. DESIGN: Review. SETTING: Department of Obstetrics and Gynecology, General Faculty Hospital Prague, 1st Faculty of Medicine, Charles University. RESULTS: This is the review on predictive factors of endometrial receptivity. There is a collected data on homeobox genes family, especially HOX 10 and HOX 11 members, that ensure implantation process by means of their interaction with estrogen and progesterone receptors via stimulatory proteins in the luminal epithelium in different periods of luteal phase. Moreover, the article describes appropriate secretion of osteoponin, cadherin, selectin, apopoliprotein D, mucin and balanced macrophage activity in endometrial epithelium in the proliferative phase of the menstrual cycle provide optimal conditions for implantation. CONCLUSION: Endometrial genes expressions along with the intrauterine environment macrophages activity maintain the tiny mechanism of endometrial receptivity.
