纤维支气管镜检查对肺癌诊断价值分析

本文报告我院从１９８３年１２月以来曾行３８００例次纤维支气管镜（简称纤支镜）检查，其中经病理证实和临床随访，最后证实肺癌者９８０例。鳞癌４５０例（４５．９１％），小细胞未分化癌２００例（２０．４％），腺癌１８０例（１８．４％），大细胞未分化癌１０例（１．０２％），肺泡细胞癌８例（０．８２％），粘液表皮样癌５例（０．５１％），病理报告癌但未分类５７例（５．８％），病理未证实，但纤支镜窥见病变，后经化疗或放疗有效，最后死于非其它疾病者７０例（７．１％）。纤支镜检阳性率为７９．５４％，同时讨论纤支镜检对本病的诊断价值。     

Duration of postlaparoscopic pneumoperitoneum

Background: Patients who present with abdominal pain after recent laparoscopic surgery present a diagnostic dilemma when pneumoperitoneum is present. Previous studies do not define the duration of postlaparoscopic pneumoperitoneum. In this study, we attempted to define the duration of laparoscopic pneumoperitoneum and to identify factors which affect resolution time. Methods: We followed 57 patients who underwent laparoscopic cholecystectomy (34), inguinal herniorraphy (20), or appendectomy (three). Serial abdominal films were taken until all residual gas was resolved. Results: Thirty patients resolved their pneumoperitoneum within 24 h; 16 patients resolved between 24 h and 3 days; nine patients resolved between 3 and 7 days; two patients resolved between 7 and 9 days. Mean resolution time for all patients was 2.6 ± 2.1 days. There was no apparent difference in resolution time between the three types of procedures; however, the sample size may be insufficient. Duration of the pneumoperitoneum did not correlate with gender, age, weight, initial volume of CO₂ used, length of time for the procedure, or postoperative complications. Sixteen patients had bile spillage during cholecystectomy which significantly reduced the duration of postoperative pneumoperitoneum (p < 0.008), resulting in a mean resolution time of 1.3 ± 0.9 days. While 14 patients reported postoperative shoulder pain, no correlation was found between the presence or duration of shoulder pain and the extent or duration of pneumoperitoneum. Conclusions: We conclude that the residual pneumoperitoneum following laparoscopic surgery resolves within 3 days in 81% of patients and within 7 days in 96% of patients. The resolution time was significantly less in patients sustaining intraoperative bile spillage during cholecystectomy. There was no correlation found between postoperative shoulder pain and the presence or duration of the pneumoperitoneum. Received: 22 March 1996/Accepted: 12 July 1996     

脑出血患者血清胃泌素水平测定及意义

目的探讨血清胃泌素水平与脑出血并发应激性溃疡之间的关系.方法用放免法测定脑出血病人发病后24小时内及恢复期血清胃泌素水平,并与正常人作对照.所获数据用t检验.结果脑出血病人发病后24小时血清胃泌素水平较正常对照组明显增高,合并应激性溃疡出血者升高更显著,恢复期病人血清胃泌素水平与正常对照组相比无显著性差异.结论胃泌素在脑出血并发应激性溃疡的发生中起重要作用.     

孤立性左肝胆管结石并肝管狭窄的外科治疗

目的总结近２０年来孤立性左肝胆管结石并发左肝胆管狭窄的临床治疗体会．方法原发性肝胆管结石１０１８例，年龄２７～７２岁，其中孤立性左肝胆管结石１３３例，手术治疗１１２例，对其临床资料进行回顾性分析，包括各肝管狭窄并发率，术前各项检查确诊率，手术治疗方式，再狭窄率．结果左肝管狭窄的发生率为５９８％，左外肝管和左内肝管分别为８４０％和８４８％，均以重度狭窄为主．狭窄切开整形后高位胆肠吻合术是处理左肝管狭窄的常用手术方式（５２２％），远期再狭窄率为１７１％；左半肝切除术施实率为１９４％，再狭窄率为００％；狭窄整形术和狭窄扩张术的施实率分别为９０％和１９４％，再狭窄率分别为５００％和９２３％．左外肝管狭窄通常采用肝段或肝叶切除术（７８７％），而左内肝管狭窄的处理则通常采用非左半肝切除术（８４８％）．左内肝管狭窄的术前／后影像学确诊率明显低于左肝管和左外肝管，平均确诊率依次２５９％，９３３％和８７９％．结论二级肝管狭窄是孤立性左肝管结石的常见并发症，肝叶或肝段切除术是其首选治疗原则．过多依赖非肝叶／段切除术和不适当的肝段切除术是遗留狭窄和远期疗效差的重要原因     

食管内支架置入术并发症分析及防治

目的：分析食管内钛镍记忆合金支架置入术并发症的可能原因及防治方法。方法：共52例病人，食管癌、贲门癌29例，食管胃吻合口狭窄21例，自发性食管破裂2例，共置入各种钛镍记忆合金支架54枚。随访观察3～36个月。结果：内支架置入全部成功，术后患吞咽困难症状均改善。术后出现的并发症包括支架移位3例，支架堵塞9例。吸入性肺炎3例，呕血7例，残余漏2例，疼痛和异物感24例，严重返流症状5例。经过相应的治疗，除2例大呕血患外，其余并发症均得到纠正。结论：虽然食管内钛镍记忆合金支架置入术后有不可忽视的并发症，但经过相应治疗，一般均可纠正，它是治疗食管恶性狭窄和自发性食管破裂有效的方法。     

妊娠期肝内胆汁淤积症与血清甘胆酸的关系

检测了７４例正常足月妊娠妇女和５６例妊娠期肝内胆汁淤积症（ＩＣＰ）患血清甘胆酸（ＣＧ）的浓度，结果ＩＣＰ患血ＣＧ浓度显升高（１３．５２±９．５４ｍｇ／Ｌ），为正常孕妇（２．６７±１．９２ｍｇ／Ｌ）的５～１０倍，根据血ＣＧ浓度将ＩＣＰ患分为〈１０、１０～２０，〉２０ｍｇ／Ｌ３组，将３组胎儿出生情况与正常组相对照，结果显示血ＣＧ浓度〈１０ｍｇ／Ｌ组羊水胎粪污染率及新生儿窒息率与正常组无差异，而     

Recurrent locking of knee joint caused by intraarticular migration of bioabsorbable tibial interference screw after arthroscopic ACL reconstruction

Two cases are reported in which, after ACL reconstruction with autologous hamstring grafts, tibial polylactide interference screws migrated into the knee joint. Clinically, both patients presented with recurrent locking of the joint. In one case, a broken 15 mm-long tip of the screw was found intra-articularly. In the other case, the whole screw had migrated into the joint cavity. The degradation process of polylactic acid, operative technique and bone quality are discussed as possible reasons for these complications.

103例流行性出血热患者的心电图及心肌酶学分析

目的了解流行性出血热病毒(EHFV)对心脏的损害情况。方法对103例流行性出血热(EHF)患者的心电图及心肌酶学检测结果进行分析。结果72例(69.9%)患者出现心电图异常,以窦性心动过缓(27.9%)及窦性心动过速(22.3%)最常见,明显高于其它类型的心电图改变(P分别<0.05和0.001)。103例流行性出血热(EHF)患者的CK、LDH及HBDH的升高者分别为43例(41.2%)、73例(70.9%)及46例(44.7%),以LDH异常最常见。轻型、中型、重型及危重型流行性出血热患者的LDH值分别为(346.3±155.6)IU/L、(330.7±130.7)IU/L、(1114.4±872.4)IU/L及(1227.1±936.7)IU/L,经统计学处理重型及危重型的值与轻型、中型比较均有显著性或高度显者性差异。结论EHF患者并发心肌损害较普遍,而且病情愈重者,心肌损害愈严重。
