Ultrastructural Observation of Fallopian Tubes in Patients with Pelvic Congestion Syndrome after Oviductal Ligation

The morphological basis of bilateral lower abdominal pain was studied by means of ultrastructural observation in patients with pelvic congestion syndrome after oviductal ligation. Fallopian tubes of 14 cases were collected during operation. Of them, 10 patients suffered from pelvic congestion syndrome, 4 cases were normal used as control, the 8 small segments from the tubal isthmus were removed during ligation. The essential changes of the fallopian tubes in patients with this syndrome were the marked swelling of the C-type unmyelinated nerve fibers, the decrease in density of axoplasm and in number of microtubules and microfilaments. The Schwann's cells were swollen as well. Furthermore, the mitochondria revealed mild to moderate swelling, their cristae decreased and shortened. However, the changes of the endings of efferent nerve fibers were not obvious.The ultrastructural changes of C-type unmyelinated nerve fibers except the endings of efferent nerve fibers were closely related to the bilateral lower abdominal pain in patients with this syndrome.

腹腔镜治疗输卵管结扎术后盆腔瘀血综合征的临床研究

目的:探讨腹腔镜下圆韧带悬吊术治疗输卵管结扎术后盆腔瘀血综合征的临床疗效。方法:应用腹腔镜下圆韧带悬吊术治疗21例盆腔瘀血综合征,术后1个月随访,了解患者症状缓解情况。结果:全部病例术后症状均有不同程度的改善,治愈率71.4％(15/21),好转率19.1％(4/21),总有效率90.5％(19/21)。结论:腹腔镜下圆韧带悬吊术方法简单、手术成功率高,是治疗盆腔瘀血综合征的一种有效治疗方法。

输卵管结扎术后盆腔静脉瘀血综合征输卵管的超微结构观察

输卵管结扎术后盆腔静脉瘀血综合征是一种独特的计划生育手术并发症。为了探讨盆腔痛的产生机理，我们于１９９２年１月至１９９３年１０月，对本综合征８例手术切除的输卵管进行了超微结构观察。结果显示Ｃ类无髓神经纤维轴突明显肿胀，轴浆密度降低，微管和微丝减少。Ｓｃｈｗａｎｎ氏细胞也明显肿胀。线粒体均为轻度至中度肿胀。传入神经末梢改变与上述轴突同，传出神经末梢未见明显改变。以上改变与患者疼痛症状密切相关。

54例女性绝育术后盆腔瘀血综合征手术和药物治疗效果比较

目的探讨输卵管绝育术后盆腔瘀血综合征(PCS)的有效治疗方法。方法选择输卵管绝育术后PCS 54例,随机分为两组,腹腔镜手术组30例(A组),药物治疗组24例(B组),通过术后随访,对两组治疗效果进行比较。结果A组,治愈率为73.3%(22/30),好转率为20.0%(6/30),无效率为6.7%(2/30),总有效率为93.3%(28/30);B组,治愈率为0,好转率为20.8%(5/24),无效率为79.2%(19/24),总有效率为20.8%(5/24)。两组总有效率比较,差异有统计学意义(P<0.01)。结论电视腹腔镜手术较药物治疗PCS有明显的效果优势,可作为治疗PCS的首先方法。

女性绝育术后盆腔静脉瘀血症的临床研究

目的探讨输卵管绝育术后盆腔静脉瘀血症的临床表现、诊断和治疗方法。方法应用腹腔镜技术和盆腔静脉造影，联合诊断５６例患者，对其术后标本作盆腔瘀血静脉病理形态学观察；治疗以手术为主。结果腹腔镜诊断符合率为９４６％（５３／５６），与盆腔静脉造影比较，对轻度、重度的诊断差异无显著性（Ｐ＞０．０５）。本组病例经治疗后治愈率为６０７％、好转率为１６１％，总有效率为７６８％；其中，手术治疗和保守性治疗的有效率分别为９０１％和１８２％。结论腹腔镜检查对本病的诊断具有重要价值，联合盆腔静脉造影检查，可作为诊断本病的主要依据。对中、重度患者应以手术治疗为宜。
