The problems and advantages of one lung ventilation during surgical intervention in pulmonary hydatid cyst disease

Background Hydatid disease is the most severe helminthic zoonosis, with an important public health problem especially in rural areas in Turkey. The aim of this study was to review the problems and advantages encountered in surgical treatment of 43 patients who were ventilated with one-lung ventilation during last four years. Methods Patients, operated with one-lung ventilation, constitute the study group. Data related to symptoms, radiographic findings, performed surgical procedures, perioperative and postoperative morbidity, hospitalization time, and cyst recurrence were collected from each individual's records. Results Cystotomy and capitonnage were performed in all cases. Perioperative complications were seen in 5 patients. Four of these 5 patients had double-lumen endotracheal tube malpositioning. In one patient hypoxemia developed. The most common postoperative complication was atelectasis. One patient had recurrent cysts. There was no perioperative or postoperative death. Conclusions We prefer cystotomy and capitonnage because it is a fast and effective technique with limited postoperative complications. One-lung ventilation prevents the exposure of lower lung areas from massive aspiration, which may cause acute obstruction of airways, and contamination by cyst contents from the operative part of the lung that causes recurrent disease. One-lung ventilation in pulmonary hydatid cyst surgery may be preferred owing to lower mortality and morbidity rates.     

Dorsal intramedullary spinal epidermoid cysts: Report of two cases and review of literature

Intramedullary epidermoid cysts of the spinal cord are rare tumors, especially those not associated with spinal dysraphism. About 50 cases have been reported in the literature. Of these, only seven cases have had magnetic resonance imaging (MRI) studies. We report two cases of spinal intramedullary epidermoid cysts with MR imaging. Both were not associated with spina bifida. In one patient, the tumor was located at D4 vertebral level; while in the other, within the conus medullaris. The clinical features, MRI characteristics and surgical treatment of intramedullary epidermoid cyst are presented with relevant review of the literature.

Complete disappearance of lung abnormalities on high-resolution computed tomography: A case of histiocytosis X

A case of pulmonary Langerhans cell histiocytosis, proved by both lung high-resolution computed tomography and lung biopsy, is described. Following smoking cessation, lung nodules and cysts gradually disappeared on serial computed tomography scans, with complete clearance of the lesions after 12 months. The role of tobacco smoking is discussed, in detail, against the background of the literature.     

胰腺假性囊肿的外科治疗：附89例报告

目的：探讨胰腺假性囊肿的治疗策略。方法：回顾性分析近5年湘雅医院普通外科收治的89例胰腺假性囊肿临床资料，根据囊肿部位、形成时间及囊壁厚度，采用非手术治疗20例，经皮囊肿穿刺引流7例，开腹手术62例（外引流8例、内引流45例、囊肿切除9例）。结果： 全组无死亡病例，手术后并发症发生率15.9%，随访3个月至5年，复发率5.6%。结论：胰腺假性囊肿的治疗宜根据情况采用不同方式，非手术治疗适于无并发症者;急诊手术应选择外引流;囊壁成熟者，选择内引流术疗效好。     

磁共振扩散加权成像技术在颅内囊性病变鉴别诊断中的应用

目的探讨磁共振扩散加权成像（DWI）技术对颅内囊性病变中表皮样囊肿、蛛网膜囊肿、脑脓肿及囊性坏死性脑肿瘤（单发囊性转移瘤、神经上皮肿瘤）的鉴别诊断价值。方法对2004年5月-2006年5月行神经外科手术治疗并经病理证实的50例颅内囊性病变患者的磁共振扩散加权成像资料进行回顾性分析．其中表皮样囊肿10例、蛛网膜囊肿10例、脑脓肿10例、单发囊性转移瘤8例及神经上皮肿瘤12例，均进行常规MRI平扫及DWI检查，生成DWI图及表观扩散系数（ADC）图，观察囊变区信号特征并测量该区的表观扩散系数值。结果（1）表皮样囊肿在扩散加权成像显示为高信号，其表观扩散系数图显示为低或稍低信号，表观扩散系数测量值为（0．924-0．12）×10^-3mm^2／s，蛛网膜囊肿扩散加权成像显示为低信号，表观扩散系数图呈高信号，测量值为（3．094-0．21）×10^-3mm^2／s；两组表观扩散系数测量值差异有统计学意义（t=22．278，P=0．000）。（2）脑脓肿之囊变区于扩散加权成像显示为高信号，表观扩散系数图呈低及等信号，表观扩散系数测量值为（0．524-0．08）×10^-3mm^2／s；单发囊性转移瘤和神经上皮肿瘤之囊变区在扩散加权成像上显示为低信号，表观扩散系数图显示为高信号。表观扩散系数测量值为（2．354-0．41）×10^-3mm^2／s，与脑脓肿组相比差异有统计学意义（t=13．939，P=0．000）。结论不同颅内囊性病变在磁共振扩散加权成像上的表现特点及病灶囊变区表观扩散系数测量值的变化。具有诊断与鉴别诊断价值。

Cystic lesions of the pineal region – MRI and pathology

Pineal lesions are rare. Tumours in this location comprise 0.4–1 % of intracranial tumours. They grow mainly as solid-mass lesions, and cystic tumours are not common. On MRI, a cystic configuration is associated usually with non-neoplastic pineal lesions rather than with a tumour, but analysis does not allow cystic pineal tumours to be distinguished from glial cysts with certainty. We compared neuroradiological and pathological data from 13 cystic pineal lesions, analysing preoperative MRI. Formalin-fixed, paraffin-embedded surgical specimens were stained routinely and immunocytochemically, using the streptavidin-biotin-complex method. Histology revealed six pineocytomas, four glial cysts, an arachnoid cyst, a low-grade astrocytoma and a teratoma. Signal characteristics of pineocytomas were similar in many respects to those of glial pineal cysts. Histomorphological analysis allowed unambiguous discrimination between pineocytomas and glial pineal cysts. Received: 19 July 1999/Accepted: 3 September 1999     

小儿先天性肺囊肿周边肺发育的观察及其临床价值

目的 探讨先天性肺囊肿(CBC)与肺发育不全的关系及其外科治疗。方法 32例CBC患儿和18例正常对照，分别测量肺泡辐射状计数(RAC值)及单位视野内第6级以上肺小动脉数(A值)。行肺小动脉Gomori醛复红弹力纤维染色；随访病例复查胸片，测量TLC、VC。结果 CBC组RAC值及A值低于正常对照，支气管型CBC的RAC值低于肺泡型；肺小动脉内、外弹性膜可见多处断裂，管壁平滑肌变性及肥厚；随访囊肿摘除及肺叶切除术后TCL、VC分别为对照的97％—98％、85％～90％。结论 CBC导致周边肺发育不全，宜尽早手术摘除。     

一期手术矫治肾输尿管重复畸形合并异位输尿管囊肿

目的 探讨分析完全性肾输尿管重复畸形合并同侧上输尿管异位囊肿的病人，治疗时是否需要同时切除病变肾和输尿管囊肿。方法 对近8年来我院收治的10名完全性肾输尿臂重复畸形合并同侧上输尿管异位囊肿的病例予以总结。结果 发现其中6名初期治疗中仅切除患侧上半肾输尿管的儿童，平均术后1年都因为膀胱内囊肿增大而再次接受了输尿管囊肿切除术。另3例病人一期同时施行了上半肾输尿管切除术、膀胱内输尿管囊肿切除术和下半肾输尿管再植术，术后随访疗效良好。结论 我们认为对类似疾病应该在切除肾输尿管的同时一并切除异位输尿管囊肿。
