胃癌术后膳食纤维和早期肠内营养与消化道并发症的关系

目的探讨胃癌术后膳食纤维和早期肠内营养(EN)与消化道相关并发症的关系。方法采用随机对照的方法,把56例胃癌术后患者随机分成能全素组和能全素加膳食纤维组,经鼻肠管进行早期肠内营养(EN),观察两组EN常见消化道并发症的发生情况。结果两组患者在临床资料方面具有可比性(P>0.05)。两组患者的术后腹胀、腹泻的发生率相似,均P>0.05,差异无统计学意义。1例能全素加膳食纤维组患者因吻合口水肿、输入袢不完全性梗阻而发生恶心、呕吐,其余患者均未发生恶心和呕吐。结论胃癌术后的早期膳食纤维EN并不增加EN消化道并发症的发生率。     

结直肠癌手术死亡相关因素分析

目的:研究旨在探讨结直肠癌手术死亡相关的临床病理影响因素.方法:回顾中山大学肿瘤防治中心1964年1月至2004年12月经手术治疗的4498例结直肠癌患者的临床病理资料,应用单因素和多因素Logistic回归分析手术死亡的相关影响因素.结果:全组手术死亡者共62例,手术死亡率为1.38%,主要死亡原因为多器官功能衰竭、中毒性休克、心血管疾病、急性肾功能衰竭、吻合口漏等.单因素分析显示,性别、术前基础疾病、术前合并症、腹水、手术年代、手术性质、Dukes分期、术后并发症等为影响手术死亡的因素,而年龄、肿瘤部位、组织类型、病理分级与手术死亡无关.多因素分析表明,术前基础疾病、术前合并症、腹水、手术年代、手术性质、Dukes分期、术后并发症是结直肠癌手术死亡的独立影响因素.结论:术前基础疾病、术前合并症、腹水、手术年代、手术性质、Dukes分期、术后并发症是结直肠癌手术死亡的独立影响因素.     

社区干预治疗对促进脑梗死患者功能恢复效果分析

目的探讨社区干预治疗对促进脑梗死患者功能恢复的效果。方法以自愿的方式选择通州区经委社区卫生服务站和八里桥社区卫生服务站所管辖社区内38例脑梗死恢复期患者随机分为治疗组和对照组,对治疗组患者进行为期1年的社区干预治疗,比较治疗组与对照组患者功能恢复情况(日常生活活动能力)。结果通过1年的早期社区干预治疗,治疗组较对照组患者功能恢复效果明显提高(P<0.01)。结论早期社区干预治疗对脑梗死患者功能恢复有促进作用。     

大肠癌术后早期肠梗阻的临床特点和治疗

目的：探讨大肠癌术后早期肠梗阻的诊断与治疗。方法：回顾分析在肠癌手术412例术后早期肠梗阻29例的临床资料。结果：20例经手术探查发现以机械性梗阻占多数（18/20)，手术治愈18例；死亡2例，死亡原因均为延误手术时机造成；非手术治愈9例。结论：大肠癌术后早期肠梗阻虽有梗阻症状，但由于术后诸多因素的影响，大多缺乏典型机械性肠梗阻的临床表现。处理中先进行适当时间的非手术治疗，无缓解者再手术。     

Endometrial carcinoma: Does the addition of intracavitary vault caesium to external beam therapy postoperatively result in improved control or increased morbidity?

A retrospective analysis of treatment for endometrial carcinoma is reported here. From 1987 to 1989, 138 patients were referred to the oncology department following total abdominal hysterectomy and bilateral salpingo-oophorectomy for endometrial cancer. Forty-seven patients were not prescribed postoperative radiotherapy; 31 had Stage I well differentiated adenocarcinoma with minimal myometrial invasion, while the remaining 16 patients were considered unfit for postoperative radiotherapy. There were no instances of local relapse amongst the 31 patients with minimal myometrial invasion.The remaining 91 patients all received external beam irradiation to the pelvis and, according to the preference of the individual therapist, 51 were prescribed additional intracavitary vault caesium-137. Patients receiving postoperative radiotherapy were analysed according to whether or not they received additional intracavitary vault caesium. The two groups were also analysed for incidence of vaginal vault recurrence and treatment related morbidity.In the group receiving additional intracavitary treatment more patients had Stage II or III disease (P<0.05), and had greater depth of myometrial invasion (P<0.05). Vaginal vault recurrence was not observed in patients receiving intracavitary therapy in addition to external beam therapy. Four patients (10%) receiving external beam therapy alone developed vaginal vault recurrence.The incidence of Kottmeier-Perez grade 2 or 3 bowel toxicity following treatment was significantly higher in those patients receiving combined treatment (18% vs. 2.5%; P<0.03). There was also a higher incidence of vaginal stenosis in the group receiving both external beam and intracavitary therapy (21% vs. 3%; P<0.05). There was only one instance of grade 2 bladder toxicity in the external beam and intracavitary treatment group and none in the external beam therapy alone group.In conclusion, postoperative radiotherapy for Stages I-III endometrial carcinoma was carried out in a non-randomized manner by two regimens; either external beam therapy alone or external beam therapy with additional intracavitary vaginal caesium. The combined therapy gave significantly better local control but resulted in significantly more late bowel and vaginal morbidity.     

SPIR扫描在诊断骨胳肌肉系统疾病中的应用

目的：探讨SPIR脂肪抑制技术在骨胳肌肉系统疾病MRI检查中的诊断价值。材料与方法：对36例骨、关节软组织疾病患者行T1W／SE、T2W／FSE及T2W／SPIR序列扫描，并对后两者进行比较。结果：各种病理性积液呈高信号；损伤性骨髓水肿呈高信号；骨折线呈低信号，如骨折断端出血则呈线状高信号；软组织肿瘤囊性部分呈高信号，实质部分呈中等强度信号；软组织炎症性病变为弥漫性高信号；骨病成骨性改变为低信号；骨髓病变为高信号或混杂等高信号；椎管内占位性病变及半月板损伤SPIR显示不清。结论：SPIR能提高正常组织与病变组织间的对比度，清晰地显示病变组织，作为T1W／SE、T2W／FSE序列的辅助检查，有助于提高骨胳肌肉系统疾病的诊断水平。

Endoscopic sealing of infected bronchus stump fistulae with fibrin following lung resections

Summary Bronchus stump insufficiency following lung resection, with an average incidence of 4%, is a serious complication which carries a mortality of up to 90%. Operative transthoracic approaches have been largely unsatisfactory because of the high operative risk and rapidly spreading infection. In an experimental study on 18 pigs, endoscopic occlusion of infected bronchus stump fistulae was achieved with fibrin sealant (1 ml, 500 units/ml thrombin, 3500 units/ml aprotinin) applied via a flexible bronchoscope. During autopsy, all bronchus stump fistulae were found to have healed after the second postoperative week. Transitory local abscesses of the pleura could be prevented by high-dose systemic antibiotic therapy for 5 postoperative days but not by antibiotics added to the fibrin sealant. This endoscopic method has already been performed successfully in 3 clinical cases; additional sclerotherapy with (2–3 ml Ethoxysclerol applied around the fistula orifice was carried out before fibrin sealing to stimulate fibrosis. Endoscopic controls demonstrated fistula closure by granulation tissue after 2 weeks. This procedure could become the method of choice for infected postoperative fistulae of the bronchus stump and should be attempted in any case before operative approaches are considered.     

Zum Einfluß von Operationszeitpunkt und Kliniksorganisation auf die postoperativen Komplikationen

Zusammenfassung Über ein Jahr wurden 1082 allgemeinchirurgische Planeingriffe prospektiv konsekutiv erfaßt und ihre Komplikationen mit einem Score bewertet. EinflußgröBen und die Komplikationsraten, die unter Umständen von der Kliniks-organisation abhängig sind, sollten analysiert werden. Es fand sich eine Beziehung zwischen Komplikationen und Wochentag, Operationsdauer sowie der Abweichung der tatsächlich benötigten von der geplanten Operationszeit. Mit höherer Auslastung der Operationssäle pro Arbeitstag stiegen die Komplikationsraten ebenfalls an.Keinen Einfluß auf die Komplikationsraten hatten Operationsbeginn und-monat sowie die monatliche Auslastung der Säle. Ob das Wetter einen Einfluß auf die Komplikationsraten nahm, konnte nicht entschieden werden: so fanden sich im Sommer- höhere Komplikationsraten als im Winterhalbjahr, jedoch war der Score von der Höhe der Außentemperatur und der Luftfeuchtigkeit unabhängig.

The influence of time of operation and hospital organization on postoperative complication rates

Summary During a 1-year period 1082 general surgical interventions were prospectively documented and their complication rates evaluated by a score system. Factors responsible for the complication rates and possibly depending on hospital organization should be analysed. The complication rates were influenced by the selection of the weekday, the length of operation time and the extent of discrepancy between planned and required operation time. Furthermore, the complication rates paralleled the extent of utilization of the operation theatre during a workday. The complication rates werenot affected by the beginning of operation and the operation month as well as the monthly utilization of the operation theatres. Whether the weather did influence the complication rates could not be decided: higher complication rates were found in the summer as compared to the winter period, but the complication score was independent of the level of the outside temperature and humidity.
