Hand-assisted laparoscopic splenectomy for hydatid cyst

Splenic hydatidosis is a rare condition. We performed a hand-assisted laparoscopic splenectomy for a large hydatid cyst localized in the center of the spleen. We discuss the advantages of the ``helping hand.' Received: 27 September 1996/Accepted: 19 November 1996     

Effects of Carbamazepine on Murine Humoral and Cellular Immune Responses

Summary: Oral administration of carbamazepine (CBZ)(15, 10, or 5 mg/kg) to mice significantly decreased both humoral and cellular immune responses evaluated by enumeration of direct and indirect plaque-forming spleen cells (PFC) and delayed–type hypersensitivity reaction (DTH) against sheep red blood cells (SRBC) as compared with those observed in normal control animals. Moreover, spleen T cells obtained from CBZ–treated donor mice were capable of decreasing both PFC and DTH responses of normal spleen cells transferred into lethally irradiated recipient animals. The immunodepressor effect of CBZ was observed even though administration of CBZ induced augmentation of spleen cellularity.

目的:观察自拟健脾止泻饮治疗糖尿病腹泻的临床疗效。方法:治疗组32例用健脾止泻饮治疗,对照组30例用维生素B1、复方苯乙呱啶、盐酸黄连素治疗。结果:治疗组总有效率93.8%,对照组总有效率56.7%,两组比较有极显著性差异(P<0.01)。结论:健脾止泻饮治疗糖尿病腹泻有较好疗效,且无不良反应和毒副作用。     

部分性脾栓塞术的临床应用：——附37例报告

应用部分脾栓塞术(PSE)治疗难治性原发性血小板减少性紫癜27例,血栓性血小板减少性紫癜1例;难治性再生障碍性贫血2例;Evan's 综合症2例;系统性红斑狼疮合并血小板减少性紫癜2例;继发性脾亢3例.获完全缓解者24例(64.9%);部分缓解者8例(21.6%),总有效率为86.S%.24例获完全缓解者18例追踪1年,6例复发,复发率为33.3%.与25例切脾对照组及文献报道比较,差异无显著性(P>0.05).本文对 PSE 术后外周血小板的变化进行讨论,并与脾切除作了对比。本文还对血小板破坏场、栓塞范围和方法等影响疗效的因素进行了探讨.作者认为 PSE 术可作为脾切除的替代术.     

Laparoscopic management of a ruptured giant epidermoid splenic cyst.

BACKGROUND: Epidermoid splenic cysts are uncommon lesions of the spleen. They are known to become symptomatic as a consequence of enlargement, infection, or rupture, the latter being an exceedingly rare complication traditionally treated with open splenectomy. We herein report a unique case of a giant epidermoid splenic cyst that ruptured spontaneously and was successfully treated with the laparoscopic approach. CONCLUSION: Laparoscopic surgery may be considered an initial treatment option in cases of very large epidermoid cysts even when rupture occurs.     

Nodular sarcoidosis of the liver and spleen: Appearance on MR images

Small nodular lesions in the liver and spleen have been reported as an infrequent manifestation of sarcoidosis. Five patients with this appearance on either dynamic contrast material—enhanced computed tomographic (CT) or ultrasound scans underwent magnetic resonance (MR) imaging with and without dynamic gadolinium enhancement. The lesions were relatively uniform in size, ranging from 0.5 to 1.5 cm. On CT scans, they were hypoattenuating relative to surrounding parenchyma. On MR images, the lesions were hypointense relative to background parenchyma with all sequences. No substantial enhancement was observed in the lesions, although lesion conspicuity decreased over time on serial postcontrast images. Lesion conspicuity was greatest on either T2-weighted fat-suppressed (T2FS) images or early-phase dynamic contrast-enhanced images. Abdominal adenopathy was seen in three of the five patients and was hyperintense relative to liver on T2FS images in two and intermediate in intensity in one patient.     

Splenic nonenhancement at computed tomography: A sign of the hypoperfusion complex

When splenic nonenhancement is seen at computed tomography, one should look for signs of vascular pedicle injury; if injury to the vascular pedicle is not present, nonenhancement of the spleen could be secondary to severe vasoconstriction and may be considered an additional sign of the hypoperfusion complex. The presence of splenic nonenhancement may also help differentiate the hypoperfusion complex from other types of bowel injury.

基于"WD倒谱"法分析人体脾组织的超声散射微结构特征

本文提出了一种对超声散射信号分析的新方法--“WD倒谱”法,并利用该方法对人体正常脾和脾增生组织的回波信号进行了分析,对软组织中散射子的平均间距进行了估计,结果表明：两种脾组织散射子的平均同距明显不同;“WD倒谱”能有效的反映软组织的微观结构特征,说明“WD倒谱”是软组织超声散射信号分析与软组织散射子平均间距定征的一种有效方法。
