鼻胃管胃肠减压在择期腹部手术中的应用价值

鼻胃管胃肠减压曾被常规应用于择期和急诊的腹部手术后，目的是预防急性胃扩张的发生、治疗梗阻、降低吻合口压力等。但是，鼻胃管置入也会带来一些副作用，如呼吸道并发症、胃-食道反流、体液和电解质的丢失、声带的损伤，以及越来越被重视的患者的不适感。近年来的研究结果也对择期的腹部手术后常规应用鼻胃管胃肠减压提出不同的看法。现重新评价应用鼻胃管胃肠减压的理论基础及相关临床研究的结果，并对鼻胃管胃肠减压在择期腹部手术中的价值作一综述。     

颅脑损伤患者脑疝前驱期特征性临床征象的研究

目的分析总结外伤性脑疝前驱期特征性临床征象及意义。方法回顾分析我科近5年238例脑疝发生前2h内的临床表现和辅助检查特点，并与同期198例未发生脑疝的重型颅脑损伤患者进行对比分析。结果脑疝组前驱期征象如昏迷加深、烦躁加重、尿失禁、侧脑室和外侧裂受压变窄伴脑基底池受压变窄、生命体征改变具有特征性，其发生率明显高于非脑疝组，两组差异有显著性意义（P〈0．01）。结论颅脑损伤患者出现脑疝前驱期特征性临床征象应作为超早期开颅的重要依据，是特殊的、迫切的手术指征。     

腹腔镜在急性肠梗阻手术治疗中的应用

目的:评价腹腔镜在急性肠梗阻手术治疗中的价值。方法:对腹腔镜急性肠梗阻手术的适应证、禁忌证、手术方式、注意事项、手术并发症及优缺点等进行了总结与分析。结果:腹腔镜手术已成功地用于治疗由既往腹部手术后粘连、内疝(包括膈疝)、腹壁疝、肠扭转等所引起的急性肠梗阻。结论:腹腔镜急性肠梗阻手术仍是一种探索性的手术,可以代替开腹手术治疗选择性的急性肠梗阻。对于梗阻原因不明者,腹腔镜手术是一种即可以明确梗阻原因,又可以同时进行有效治疗的方法。     

TECHNIQUES AND PITFALLS OF ENDOSCOPIC SUBMUCOSAL DISSECTION FOR COLORECTAL TUMORS

Endoscopic submucosal dissection (ESD) for colorectal tumors is steadily being developed. Safety and standardization of ESD for colorectal tumors have not been yet established because of the technical difficulties and the unsuitable anatomical characteristics of the colon and rectum. The authors mainly use a Flex knife for mucosal incision and a Hook knife for submucosal dissection to perform ESD safely. Skillful colonoscopic control, selection of scope, distal attachment tip hood, adequate high‐frequency generator and correct approach strategy should all be considered for safe performance of ESD. However, the incidence of indicative lesions is rare because the majority of colorectal tumors are adenomatous large laterally spreading tumors, which can be cured by intentional endoscopic piecemeal resection. At present, ESD for colorectal tumors should be performed only at central facilities that have expert colonoscopists. With the development of new devices and associated techniques, technical standardization of ESD for colorectal tumors is expected in the near future.     

Diffuse Axonal Injury (DAI) is not Associated with Elevated Intracranial Pressure (ICP)

Summary Objective. Traditionally, intracranial pressure (ICP) monitoring has been utilized in all patients with severe head injury (Glasgow coma score of 3–8). Ventriculostomy placement, however, does carry a 4 to 10 percent complication rate consisting mostly of hematoma and infection. The authors propose that a subgroup of patients presenting with severe head trauma and diffuse axonal injury without associated mass lesion, do not need ICP monitoring. Additionally, the monitoring data from ICP, MAP, and CPP for a comparison severe head injury group, and subgroups of DAI would be presented. Materials and methods. Thirty-six patients sustaining blunt head trauma and fitting our strict clinical and radiographic diagnosis of DAI were enrolled in our study. Inclusion criteria were severe head injury patients who did not regain consciousness after the initial impact, and whose CT scan demonstrated characteristic punctate hemorrhages of <10 mm diameter at the greywhite junction, basal ganglia, corpus callosum, upper brainstem, or a combination of the above. Patients with significant mass lesions and documented anoxia were excluded. Their intracranial pressure (ICP) and cerebral perfusion pressure (CPP) were compared to a control group of 36 consecutive patients with severe non-penetrating non-operative head injury, using the Analysis for Variance method. Results. Eighteen (50.0%), six (16.7%), and twelve (33.3%) patients had types I, II, and III DAI, respectively. The admission Glasgow Coma Score (GCS) was higher for types I and II than for type III DAI. ICP was monitored from 23 to 165 hours, with a mean ICP for 36 patients of 11.70 mmHg (SEM=75) and a range from 4.3 to 17.3 mmHg. Of all ICP recordings, of which 89.7% (2421/2698) were ≤20 mmHg. Average mean arterial pressure (MAP) was 96.08 mmHg (SEM=1.69), and 94.6% (2038/2154) of all MAP readings were greater than 80 mmHg. Average cerebral perfusion pressure (CPP) was 85.16 mmHg (SEM=1.68), and 90.1% (1941/2154) of all CPP readings were greater than 70 mmHg. This is compared to the control group mean ICP, MAP, and CPP of 16.84 mmHg (p=0.000021), 92.80 mmHg (p=0.18), and 76.49 mmHg (p=0.0012). No treatment for sustained elevated ICP>20 mmHg was needed for DAI patients except in two; one with extensive intraventricular and subarachnoid hemorrhage who developed communicating hydrocephalus, and another with ventriculitis requiring intrathecal and intravenous antibiotic treatments. Two complications, one from a catheter tract hematoma, and another with Staph epidermidis ventriculitis, were encountered. All patients, except type III DAI, generally demonstrated marked clinical improvement with time. The outcome, as measured by Glasgow Coma Score (GCS) and Glasgow Outcome Score (GOS) was similarly better with types I and II than type III DAI. Conclusion. The authors conclude that ICP elevation in DAI patients without associated mass lesions is not as prevalent as other severe head injured patients, therefore ICP monitoring may not be as critical. The presence of an ICP monitoring device may contribute to increased morbidity. Of key importance, however, is an accurate clinical history and interpretation of the CT scan.     

非脱垂子宫经阴道与经腹切除的比较

目的：对非脱垂的良性子宫疾病全子宫切除的不同方法进行评价,以便合理地制定手术方案,方法：非脱垂子宫行阴道全子宫切除（VH）15例,随机选择同期良性子宫疾病行经腹全子宫切除术（TAH）15例,采用对照研究方法,对一般临床资料,手术、术后恢复、住院日和费用等进行对照分析。结果：VH2例中转经腹手术,成功率87％,两组一般临床资料、诊断、子宫大小、麻醉、手术范围、失血量差异无显著性,VH术后无伤痛,用止痛药仅23％,TAH15例均有伤口痛,用止痛药47％,住院日、经费及总费用VH明显少于TAH,两组差异有显著意义（P＝0．0027、0．0447、0．0162）。结论对良性子宫疾病全子切除VH显示的优势特别适合我国国情,大子宫并非手术禁忌,明确VH的禁忌以利于VH在临床推广应用。     

剖宫产率及指征变化与围产儿死亡率的关系

目的 探讨剖宫产率及剖宫产指征变迁对围产儿死亡率的影响。方法 对10年间剖宫产病例资料进行回顾分析。结果 1993至1997年剖宫产率为30．34％，显著低于1998至2002年的45．30％r，两者比较差异有极显著性(P＜0．01)。在剖宫产指征中，妊娠并发(合并)症始终处于第1位，社会因素上升为第2位，头盆不称为第3位，胎儿窘迫为第4位。围产儿死亡率1993至1997年为16．85％。，1998至2002年为17．79％，两者比较，差异无显著性(P＞0．05)。结论 剖宫产率升高在一定范围内降低了围产儿死亡率，但随着剖宫产率的进一步升高，围产儿死亡率并未随之下降。因此，应合理掌握剖宫产指征，降低剖宫产率。
