AIM

To evaluate the value and safety of endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic treatment in acute biliary pancreatitis.

METHODS

Ninety-one patients with acute biliary pancreatitis including 13 patients with severe acute biliary pancreatitis in the ERCP group underwent ERCP and endoscopic therapy. 15 patients with severe acute biliary pancreatitis were not treated by either surgery, endoscopy or early ERCP in the control group. Etiological factors, therapeutic effects and complications were observed in all the patients of the two groups.

RESULTS

In ERCP group, ERCP showed biliary tract disease in 56 cases, common bile duct stones in 26, cholecyst stone in 17, microcholelith in 4, cholangitis in 9, larger diverticula around the papilla in 3, papillitis in 5, pancreatic diverticulum in 2, and normal in 25. 46 cases of biliary tract disease were treated by endoscopy including papillosphincterotomy, endoscopic nasal biliary drainage and endoscopic dilatation of the accessory papilla. There were no significant differences in the recovery days of serum amylase back to normal between ERCP group (3.4±1.6 d) and control group (4.5±2.8 d), but the mean days of disappearance of abdominal pain (4.4±2.0 d), fever (5.0±3.4 d), abnormal white blood cell count (6.5±5.4 d) and hospitalization (21.9±8.4 d) were significantly shorter in the ERCP group than in the control group (8.4±6.1 d, 16.1±19.0 d, 19.1±19.3 d, 41.3±20.0 d, P<0.05). Complication rate (53.9%) and mortality rate (0%) in ERCP group were lower than those of control group (80.0%, 23.1% P<0.05). 17 cases had early complication (18.7%) in ERCP group. Of them, biliary tract infection occurred in 2 cases (2.2%), retroperitoneal pneumatosis in 1 case (1.1%), bleeding of digestive tract in 1 case (1.1%), deterioriation of pancreatitis in 13 cases. 15 patients were cured by medication treatment. Operations were performed in one patient. One patient died.

CONCLUSION

ERCP and endoscopic therapy are safe and effective for patients with acute pancreatitis.

0 引言

急性胆源性胰腺炎(acute biliary pancreatitis, ABP)是消化系常见急症, 并发症(15-50%)和死亡率(20-35%)高, 早期诊断、采取适合的治疗措施非常重要[1,2]. 近年来, 通过内镜逆行胰胆管造影(endoscopic retrograde cholangi-opancreatography ERCP)进行内镜下乳头括约肌切开(endoscopic sphincterotomy, EST)及内镜鼻胆管引流术(endoscopoc nasobiliary drainage, ENBD), 已成为治疗的重要治疗手段[3]. ERCP及ENBD可以明确ABP的病因, 指导采取合适的措施, 降低死亡率和并发症[4]. 我院自2000-01/2002-01对91例ABP患者作了ERCP及ENBD, 其中的13例重症急性胆源性胰腺炎(severe acute biliary pancreatitis, SAP)与同期行保守治疗的15例SAP患者进行对照研究, 以探讨其应用价值及安全性如下.

1 材料和方法
1.1材料

91例ABP中男49例, 女42例, 年龄18-75(平均51±14)岁. 入院即刻行CT检查48例, Bakthazar A级15例(31.3%), B级18例(37.5%), C级8例(16.7%), D级4例(8.3%), E级3例(6.3%). A, B, C级症状无好转者72 h内再次行CT检查12例, 其中D、E级9例, 结合Ranson及APACHE II评分, 确定SAP13例, 轻型胰腺炎78例. 选取同期保守治疗的15例SAP为ERCP组中SAP的对照组. ERCP组SAP的Ranson及APACHE II评分分别为3.2±0.9和9.8±2.8, 与对照组SAP (2.8±0.9, 9.7±6.3)相比无明显差别(P>0.05). Bakthazar CT分级两组无差别(P>0.05).

1.2方法

ABP常规给予禁食、胃肠减压、抑酶抑酸及预防感染治疗. 对伴随梗阻性黄疸、化脓性胆管炎、胆总管扩张的SAP, 治疗24 h未好转, 24-72 h内急诊ERCP及ENBD. 轻型胰腺炎具有胆总管结石、胆总管扩张等ERCP指征者, 于症状消失、淀粉酶及白细胞正常后择期行ERCP. ERCP组患者术前10-15 min静注地西泮5-10 mg、丁溴东莨菪碱20 mg和(或)哌替啶25-50 mg. 内镜选用Olympus JF-200、JF-230及JF-30型十二指肠镜, 造影剂选用30 g/L泛影葡胺, 操作者均为相对固定、有一定经验的医生和护士, 争取行胆管及胰管分别显影, 胰管造影时控制造影次数(小于3次)、造影剂量及腺泡造影, 常规作X线摄片. ERCP术后常规禁食12-24 h, 并常规给予预防感染、补液治疗. 行EPT者静滴止血药. 胰管显影、术后3 h淀粉酶高于正常者加抑酶抑酸治疗. 观察SAP的腹痛缓解天数, 体温正常时间, 淀粉酶正常时间, 白细胞正常时间及平均住院天数. 详细记录ERCP组并发症情况及处理.

统计学处理 均数的统计采用两组完全随机化t检验. 率的显著性差异采用Fisher的精确检验.

2 结果

ERCP91例均成功. 胆总管结石26例, 微胆石4例, 单纯胆囊结石17例, 胆管炎9例, 乳头旁巨大憩室3例, 胰腺分裂症2例, 乳头及胆总管下端炎症5例, 共66例明确了病因. 25例ERCP未见异常. 对有内镜治疗指征者进行相应治疗: 有21例胆管结石, 1例乳头狭窄及3例胆总管下端炎症患者在ERCP的同时施行内镜下十二指肠乳头括约肌切开术(EPT)及取石术, 19例有胆管多发结石及碎石者作了鼻胆管引流术, 2例次胰腺分裂症患者作了副乳头插管造影及扩张治疗. ERCP组中SAP的腹痛缓解天数, 体温正常时间, 白细胞正常时间及平均住院天数明显短于对照组. 淀粉酶正常时间两组无明显差别(表1). ERCP组SAP的并发症发生率(80% vs 54%)和死亡率(23% vs 0%)明显低于对照组(P<0.05).

3 讨论

在西方国家BP占胰腺炎年发病数的34-54%, 我国在60%以上, 其次为酒精性及先天性(如胰腺分裂症)[5,6]. ERCP在明确病因方面有较大优势. B超、CT显示胆石的敏感性和特异性约为50 -70%, 而ERCP诊断结石的敏感性可达95-100%. 本组91例ERCP检查56例为胆道疾患, 特别是胆道微结石可能占相当比例(文献报道5-7%), 常规影像学包括ERCP常不能确诊, 经内镜取胆汁镜检是确定诊断的惟一方法[7]. 本组微胆石4例, 占6.1%. 胰腺分裂、 胰管结石及乳头旁巨大憩室亦占一定的比例, 为不可忽视的发病因素. 有胆管炎、黄疸、胆总管扩张的BP, 或症状进行性加重, ERCP+EST应尽早进行, 最为理想的是发病后24 h内施行[8,9]. 轻症胆源性胰腺炎和临床症状好转者, 如有指征可待病情平稳后进行. 本组资料显示, 13例SAP患者在发病后4-72 h进行ERCP及EST, 可见突发释放出浓缩胆汁和脓液, 患者病情改善, 同时住院时间、并发症和死亡率显著低于常规治疗组[10,11]. ERCP及EPT具有创伤小, 操作相对较简单, 成功率高等优点[12]. 本资料表明早期ERCP后出现胆道感染2例(2.2%), 经ENBD及内科保守治疗痊愈. ERCP后胆管感染是常见的并发症, 通常是由于器械污染、向胆管内注入过量的造影剂、胆管狭窄、胆管结石或碎石未彻底取干净引起胆汁引流不畅而致感染及败血症. 本组病例提示, 伴有胆管狭窄和实施碎石后的胆源性胰腺炎应特别重视, 一方面尽量少注造影剂, 另外要保证引流通畅. ERCP术后胆道感染病情凶险, 要早期处理, 最重要的是ENBD, 尽快胆道减压, 同时加强抗生素治疗. 消化道大出血1例发生于伴有乳头旁巨大憩室、化脓性胆管炎的胰腺炎, 行EST取石后出现大出血, 内镜治疗及动脉插管栓塞治疗无效, 转外科手术治疗痊愈. EST后出血量一般较少且为自限性, 不必停止操作. 大的出血多由于切割了十二指肠后动脉血管变异分支, 也可能为患者伴有凝血机制障碍. 此时可用乳头切开刀的凝固和混合电流予以烧灼止血, 也可用内镜注射针向括约肌切开部位注射0.1 g/L肾上腺素, 出血凶猛时可用金属夹止血, 若仍无效应行动脉插管栓塞治疗或急诊外科手术治疗[13]. SAP多伴有梗阻性黄疸、胆道感染甚至败血症, 出血危险性相对加大, 应力求简单有效的操作, 不可一味追求一次完全解决问题, 盲目实施复杂操作. 胰腺炎加重13例(14.3%), 术后变为SAP死亡1例(1.1%). 该患者为轻型胆源性胰腺炎症状消失后行ERCP, 距胰腺炎发病7 d, 手术中乳头插管困难, 反复插管多次才造影成功, 未见胆总管结石, 未行EPT. 术后5 h出现剧烈腹痛、恶心呕吐、血淀粉酶和白细胞明显增高, 并发多器官功能衰竭2 d后死亡. ERCP后胰腺炎的发生可能与插管困难, 反复多次胰管显影, 注入过量造影剂, 对胰管开口造成机械性损伤等因素有关. 多数患者仅有一过性血淀粉酶升高或伴有恶心、呕吐、腹痛及左上腹轻压痛等急性胰腺炎表现, 多无腹膜炎, 经3-5 d内科保守治疗可完全恢复. 但有少数患者一般情况差, 病情复杂, 可发展成出血坏死型胰腺炎甚至死亡. 应认识到急性胰腺炎是一严重的全身性疾病, 要积极完善术前检查, 严格选择适应证, 除外ERCP检查及治疗的禁忌证. ERCP操作中, 争取选择性插管, 避免胰管显影. 注射造影剂压力及速度均应严格控制, 以显影能明确诊断即可, 禁忌过量造影及腺泡显影. ERCP后, 仍应进行全面的积极治疗, 直至完全恢复为止. 本组重症胰腺炎行ERCP及内镜治疗后未出现严重并发症, 可能与严格选择适应证, 尽早进行内镜干预, 并由经验丰富的医师实施手术, 术中尽量采取简单有效治疗措施有关[14].

近年来, 内镜介入治疗已成为急性胆源性胰腺炎的一个重要治疗手段, 并取得了较为满意的效果[15-20]. 2002年美国国立卫生院发布的急性胰腺炎诊疗规范和2002-03在泰国召开的亚太胃肠病学会议发布的急性胰腺炎诊治规范中均将内镜治疗列为水肿性和坏死性胆源性胰腺炎的早期治疗措施加以推荐[21].

文献报道的ERCP术后并发症发生率差异较大, 如急性胰腺炎的发生率为从0.74%到5.2%不等[22]. 可能与评判标准、研究方法、患者组成、操作复杂程度及操作水平不同有关. 目前认为的危险因素有插管困难、括约肌预切开、初级ERCP医师、胰管显影剂胆管引流不畅等[23-27]. 从本组情况来看, SAP患者行ERCP可发现确切病因, 内镜治疗是有效的, 安全的. 为了减少ABP实施ERCP及内镜治疗的危险性, 我们认为应注意以下方面: (1)治疗性ERCP必须由技术熟练的内镜医师操作, 成功率应在90%以上; (2)ERCP时应尽量避免胰管显影; (3)在ERCP的同时进行EST, 尽可能在首次内镜下完全清除胆总管内结石; (4)取石失败并估计自发排石困难者和ERCP或EST失败的患者都应立即进行手术治疗; (5)尽可能在24 h内行EST, 超过72 h EST则并发症增加[32,33].
