目的 调查胃肠道疾病患者围手术期的疼痛状况，为建立无痛病房，优化医疗和护理服务提供依据。 方法 对2011年12月5日－2012年1月14日胃肠外科所有的新住院患者共227例，采用《四川大学华西医院住院病人疼痛现状调查问卷》进行调查，并同期调查胃肠外科27名主管医师对疼痛药物了解状况。 结果 有明确行为能力的216例患者完成调查问卷，其中有195例（90.28%）接受手术治疗，全身麻醉患者193例（占手术患者98.97%），诊断为胃肠道肿瘤163例（占手术人数的83.59%），手术等级为三级146例（占手术人数的74.87%）。有168例（86.15%）患者术后镇痛，在术后镇痛过程中使用镇痛泵156例（92.86%），其中75例（48.08%）认为镇痛泵镇痛“基本有效”，30例（19.23%）认为“无效”。39例术后未使用镇痛泵，其中20例（51.28%）认为“未使用术后镇痛泵”最主要原因为“不了解镇痛泵”。受调查的主管医师了解的疼痛药物仅占罗列药物52种的（20 ± 5.36）种。 结论 疼痛现象在胃肠道疾病围手术期患者中属普遍现象，由于不断增强镇痛意识和镇痛需求与相关知识缺乏的矛盾存在，及较少的医疗护理干预，导致镇痛效果不佳，影响了疼痛管理长效机制的建立和无痛病房的建设。
目的 探讨腹腔镜胃肠道手术常见戳孔并发症的特点及防治对策。方法 回顾性分析我院78例行腹腔镜胃肠道手术后9例发生戳孔并发症患者的临床资料。结果 9例中戳孔感染4例，戳孔周围皮下瘀血和血肿2例，戳孔疝1例，皮下气肿2例，经采取拆除戳孔处缝线、通畅引流、换药、局部压迫、药物止血等相应处置，患者均痊愈出院。结论 戳孔并发症重在预防，其危害不容忽视。
ObjectiveTo summarize the application of spectral CT in the diagnosis of common, frequently occurring, and acute severe gastrointestinal diseases. MethodThe literature and guidelines on spectral CT were reviewed, and the main conclusions and opinions were summarized. ResultsThe spectral CT could obtain a variety of tissue parameters through a single scan. Through post-processing, multiple sequence images could be obtained, including virtual single-level images, virtual unenhanced images, iodine density images, effective atomic number images, etc. And multiple quantitative indicators could also be obtained, including iodine concentration, standardized iodine concentration, spectral curve, effective atomic number, etc. It could improve the signal-to-noise ratio of the image, reduce artifacts, increase iodine contrast, and decrease iodine load, then could improve the detection rate of active gastrointestinal bleeding and ischemic bowel diseases, improve the assessment accuracy of inflammatory activity of Crohn disease, and help to identify benign and malignant gastrointestinal tumors, determine the histological origin and evaluate the therapeutic effect. ConclusionFrom the conclusion summarized in this review, spectral CT images and quantitative indicators could provide more valuable information for detection, diagnosis, and prognosis of gastrointestinal diseases.
