摘要 目的：对比分析冷刀系统与宫腔镜下能量系统分别联合芬吗通治疗中重度宫腔粘连疗效。方法：选取2020年1月-2022年1月我院收治的中重度宫腔粘连患者80例为研究对象,分为对照组（n=40）和观察组（n=40）。对照组采用宫腔镜下能量系统联合芬吗通治疗,观察组采用冷刀系统联合芬吗通治疗。对比两组临床指标、临床疗效、月经恢复情况、并发症发生情况。结果：观察组手术时间、术中出血量、手术次数、术后出血量均短/少于对照组（P<0.05）。术后12个月观察组临床疗效（90.00%）显著高于对照组（65.00%）（P<0.05）。术后8~14个月两组的月经恢复情况均改善,观察组月经恢复情况较对照组更优（P<0.05）。观察组术后感染、子宫腺肌病、子宫穿孔、水中毒等并发症的总发生率（7.50%）低于对照组（47.50%）（P<0.05）。结论：冷刀系统联合芬吗通治疗宫腔粘连具有显著疗效,不仅对患者的危害更小,还有利于月经恢复,减少并发症,改善预后。     

宫腔镜下子宫内膜电切术联合刮宫术治疗多发性子宫内膜息肉的效果探讨

目的:探讨宫腔镜下采取子宫内膜电切术联合刮宫术对于治疗多发性子宫内膜息肉(EMP)患者的临床效果。方法:选取2012年6月至2014年3月在我院确诊为EMP的患者100例,随机平均分为两组,研究组采取宫腔镜下子宫内膜电切术联合刮宫术治疗,对照组单纯采取宫腔镜下子宫内膜电切术治疗。观察两组患者术中出血量、手术时间、一年内子宫息肉的复发率及子宫异常出血的发病率。结果:两组术中出血量、手术时间及子宫息肉复发率比较差异无统计学意义(P0.05)。研究组子宫异常出血发病率低于对照组,差异有统计学意义(P0.05)。结论:宫腔镜下电切术联合刮宫术对于治疗EMP的效果更佳,可降低子宫异常出血发病率,安全有效,值得临床进一步推广。     

Laparoscopic appendectomy to remove a metallic foreign body in a wild Bornean orangutan (Pongo pygmaeus) undergoing rehabilitation

A laparoscopic appendectomy was performed in a wild orangutan (Pongo pygmaeus) undergoing rehabilitation, for a metal nail found on radiographs, using 3‐mm instrumentation. Post‐operative healing was rapid and uneventful, with return to the forest within 10 days. This is the first report of minimally invasive surgery in a wild orangutan.

Maturity and fertility of rhesus monkey oocytes collected at different intervals after an ovulatory stimulus (human chorionic gonadotropin) in in vitro fertilization cycles

In rhesus monkeys undergoing ovarian stimulation for in vitro fertilization (IVF), a midcycle injection of human chorionic gonadotropin (hCG) substitutes for the LH surge and induces preovulatory oocyte maturation. The time interval between injection and oocyte collection, ideally, allows for the completion of oocyte maturation without ovulation, which would reduce the number of oocytes available for harvest. To evaluate the influence of this time interval on oocyte parameters following hCG administration, we conducted a series of gonadotropin treatment protocols in 51 animals in which the interval from hCG administration to follicular aspiration was systematically varied from 27 to 36 hr. Follicle number and size, evaluated prior to hCG administration by sonography, did not vary significantly or consistently with preovulatory maturation time. Oocytes were harvested by laparotomy or laparoscopy, and scored for maturity before insemination. The percentage of mature, metaphase II (MII) oocytes at recovery increased significantly with increasing preovulatory time and was inversely proportional to that of metaphase I (MI) oocytes. However, oocyte yield tended toward a progressive decrease with increasing preovulatory maturation times from a high of 27 oocytes at 27 hr to a low of 17 oocytes/animal at the 36 hr time interval. Fertilization levels declined significantly from a high of 50% at 27 hr to a low of 30% at 36 hr. Thus, although higher percentages of mature oocytes were recovered at the longer time intervals, optimal oocyte/embryo harvests were realized after the shorter time intervals (27 and 32 hr) and are most compatible with the goal of achieving high yields of fertile oocytes and embryos following gonadotropin stimulation in rhesus monkeys. © 1996 Wiley-Liss, Inc.     

The use of nomegestrol acetate in rapid preparation of endometrium before operative hysteroscopy in pre-menopausal women

The presence of a thin endometrium has an important role in allowing the best conditions for hysteroscopic surgery. Here, we explored the efficacy of a 14-day administration of nomegestrol acetate, a progestogen with high progestogen potency effects, in rapid endometrial preparation to operative hysteroscopy.A total of 86 fertile women selected for operative hysteroscopy received for 14 days either 5 mg day⁻¹ of nomegestrol acetate (n = 43; group A) or 4 mg day⁻¹ of folic acid (n = 43; group B), starting on day 1 of the subsequent menstrual cycle. Before treatments on days 12-14 of the menstrual cycle, all patients underwent endometrial thickness measurement; ultrasonography of the ovaries to measure the appearance of a dominant follicle; diagnostic hysteroscopy with endometrial biopsy; plasma estradiol (E2), progesterone (P), luteinising hormone (LH) and follicle-stimulating hormone (FSH) levels measurements. On the day of surgery, patients repeated endometrial and ovarian ultrasonography and, E2, P, LH and FSH measurement.At enrolment, endometrial thickness, mean follicular diameter and E2, P, LH and FSH concentrations did not differ between groups. At the time of operative hysteroscopy (i.e., after 14 days’ treatment) group A, but not group B, showed significant (all P < 0.001) reduction of endometrial thickness, mean diameter of dominant follicle, E2, P and LH concentrations. Endometrial preparation was judged more effective in group A than B, since the endometrial mucosa in all of the women of group A appeared to be very thin, hypotrophic, regular and pale. In conclusion, administration of nomegestrol acetate was effective in reducing endometrial thickness, also acting on the hypothalamus-pituitary-ovarian axis, thus allowing highly favourable operative hysteroscopic conditions.
