一种引流效果好的ERCP手术用引流管A drainage tube for ERCP surgery with good drainage effect

技术领域technical field

本发明涉及微创医疗技术及手术器械，尤其涉及一种引流效果好的ERCP手术用引流管。The invention relates to minimally invasive medical technology and surgical instruments, in particular to a drainage tube for ERCP surgery with good drainage effect.

背景技术Background technique

胆总管结石是我国的常见病和多发病，结石堵塞胆总管可导致胆汁排泄不畅，进而诱发急性胆管炎、梗阻性黄疸、肝损害等并发症，出现寒战、发热、腹痛、黄疸等表现，重者甚至导致休克，长期的结石刺激有发生胆管癌的风险，是危害人类健康的重要疾病。目前胆总管结石的治疗方案包括开腹胆道探查取石、腹腔镜胆道探查取石、内镜逆行胰胆管造影(ERCP)取石、经皮经肝胆管穿刺(PTCD)+瘘道扩张+经皮经肝胆道镜(PTCS)取石、经PTCD途径十二指肠乳头球囊扩张囊取石等。对于高龄、基础疾病多、心肺功能障碍等高危患者，根治性手术的风险较大，而PTCD引起的胆汁丢失不易于机体的恢复，目前多所采镜ERCP途径的胆道内引流术，待病情稳定后再行根治性手术。Common bile duct stones are a common and frequently-occurring disease in my country. Blockage of the common bile duct by stones can lead to poor bile excretion, which in turn induces complications such as acute cholangitis, obstructive jaundice, and liver damage, resulting in chills, fever, abdominal pain, and jaundice. In severe cases, it may even lead to shock. Long-term stone stimulation may lead to the risk of cholangiocarcinoma, which is an important disease endangering human health. The current treatment options for common bile duct stones include open biliary exploration, laparoscopic biliary exploration, endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiocentesis (PTCD) + fistula dilation + percutaneous transhepatic bile duct Endoscopic (PTCS) stone removal, duodenal papillary balloon dilatation via PTCD, and so on. For high-risk patients such as advanced age, many underlying diseases, and cardiopulmonary dysfunction, the risk of radical surgery is high, and bile loss caused by PTCD is not easy to recover. Radical surgery is then performed.

经内镜逆行胰胆管造影(ERCP)是目前治疗肝胆胰疾病的一种微创手术方案，具有创伤小、恢复快、并发症少等优点。ERCP操作也存在出血、急性胰腺炎、急性胆管炎等并发症，其中急性胆管炎的发病原因是胆管反复插管、乳头括约肌切开及扩张后引起十二指肠乳头括约肌水肿，导致胆管开口炎性狭窄，胆汁排泄不畅引起胆管高压所致。目前ERCP术后急性胆管炎的预防方案包括药物保守治疗、内镜下胆管支架置入术(ERPD)及内镜下鼻胆引流术等。Endoscopic retrograde cholangiopancreatography (ERCP) is a minimally invasive procedure for the treatment of hepatobiliary and pancreatic diseases. It has the advantages of less trauma, faster recovery and fewer complications. ERCP also has complications such as bleeding, acute pancreatitis, and acute cholangitis, among which acute cholangitis is caused by repeated bile duct intubation, papillary sphincter incision and dilation, resulting in edema of the duodenal papillary sphincter, leading to bile duct opening inflammation. Sexual stricture, bile duct hypertension caused by poor bile excretion. The current prevention programs for acute cholangitis after ERCP include conservative drug treatment, endoscopic biliary stent placement (ERPD) and endoscopic nasobiliary drainage.

为了预防ERCP并发症中的急性胆管炎，术后留置鼻胆管是目前的重要方法，在充分引流胆汁，降低胆管压力的同时，可经过鼻胆管使用抗生素溶液进行胆管冲洗，促进感染性胆汁、脓液、胆泥及碎石的排出。目前使用的鼻胆管包括襻式鼻胆管和单猪尾鼻胆管两种，两种鼻胆管管壁上圆形侧孔均位于头端，如果鼻胆管放置到深部的肝内胆管，则对其他肝内胆管及肝外胆管无引流作用；引流管侧孔较小，且数量有限，其引流胆汁有限，且容易发生堵塞。因此部分患者术后鼻胆管无胆汁引出或胆汁引流量较少，达不到有效引流的目的。In order to prevent acute cholangitis in ERCP complications, postoperative indwelling nasobiliary duct is an important method at present. While fully draining bile and reducing the pressure of the bile duct, antibiotic solution can be used to flush the bile duct through the nasobiliary duct to promote the infection of bile and pus. Discharge of fluid, bile sludge and gravel. Currently used nasobiliary ducts include looped nasobiliary ducts and single pigtail nasobiliary ducts. The circular side holes on the walls of both nasobiliary ducts are located at the head end. If the nasobiliary duct is placed in the deep intrahepatic bile duct, it will The bile ducts and extrahepatic bile ducts have no drainage function; the side holes of the drainage ducts are small and limited in number, and the drainage of bile is limited and easily blocked. Therefore, some patients have no bile drainage from the nasobiliary duct or less bile drainage after surgery, which cannot achieve the purpose of effective drainage.

除了上述外引流管，另一种重要的方法是设置如胆管支架的胆道内引流管，目前所应用的胆道内引流管多为两端设有防滑侧翼的胆管支架，或单猪尾胆管支架，上述引流管两端管壁上设有圆形侧孔，以充分引流肝外胆管内胆汁、胆泥及泥沙样结石。由于侧孔较小，数量较少，容易发生引流管侧孔堵塞，导致胆汁引流不畅，失去了充分引流胆汁的作用。In addition to the above-mentioned external drainage tube, another important method is to set up a bile duct drainage tube such as a bile duct stent. The currently used bile duct drainage tubes are mostly bile duct stents with anti-skid flanks at both ends, or single pigtail bile duct stents. There are circular side holes on the walls of both ends of the drainage tube to fully drain bile, bile mud and sediment-like stones in the extrahepatic bile duct. Because the side holes are small and the number is small, the side holes of the drainage tube are prone to blockage, resulting in poor bile drainage and loss of adequate bile drainage.

同样地，急性胰腺炎发病的主要原因是胆管反复插管、乳头括约肌切开及扩张后引起十二指肠乳头括约肌水肿，导致胰管开口炎性狭窄，胰液排泄不畅引起胰管高压所致。目前ERCP术后胰腺炎的预防方案包括药物保守治疗及内镜下胰管支架置入术(ERPD)两种。Similarly, the main cause of acute pancreatitis is the edema of the duodenal papillary sphincter after repeated bile duct intubation, papillary sphincter incision and dilation, resulting in inflammatory stenosis of the opening of the pancreatic duct, and poor excretion of pancreatic juice resulting in pancreatic duct hypertension. . The current prevention programs for pancreatitis after ERCP include conservative drug therapy and endoscopic pancreatic duct stenting (ERPD).

药物治疗主要是通过抑制胰液分泌来降低胰管压力，或者抑制胰酶活性来预防胰腺炎；ERPD是通过十二指肠乳头放置胰管支架，通过支架将胰管内胰液引流至十二指肠来降低胰管压力。其中，ERPD疗效确切，是预防ERCP术后急性胰腺炎的主要手术方案。目前使用的胰管支架包括直形带倒刺的胰管支架、单猪尾胰管支架和双猪尾胰管支架三种。虽然放置胰管支架能显著降低ERCP术后急性胰腺炎发生率，但是同时也增加了高淀粉酶血症的发生率。与急性胰腺炎相比，高淀粉酶血症虽然不会引起胰腺炎水肿，患者亦不会出现腹痛症状，但是血液中过高的淀粉酶对全身各个脏器同样存在损害，术后需要仍需要药物治疗。Drug treatment is mainly to reduce pancreatic duct pressure by inhibiting pancreatic juice secretion, or inhibit pancreatic enzyme activity to prevent pancreatitis; ERPD is to place a pancreatic duct stent through the duodenal papilla, and drain the pancreatic juice from the pancreatic duct to the duodenum through the stent. Reduce pancreatic duct pressure. Among them, ERPD has definite curative effect and is the main surgical plan for preventing acute pancreatitis after ERCP. Currently used pancreatic duct stents include straight barbed pancreatic duct stents, single pigtail pancreatic duct stents and double pigtail pancreatic duct stents. Although the placement of pancreatic duct stents can significantly reduce the incidence of acute pancreatitis after ERCP, it also increases the incidence of hyperamylaseemia. Compared with acute pancreatitis, although hyperamylaseemia does not cause edema of pancreatitis, and the patient does not experience abdominal pain, excessive amylase in the blood also damages various organs of the body, and it is still necessary after surgery. medical treatement.

置入胰管支架虽然能引流主胰管内的胰液，进而降低主胰管压力。但是，目前使用的胰管支架管壁上侧孔有限，而胰管分支较多，管壁上的侧孔不足以引流所由分支胰管内的胰液。对于部分胰管无扩张者，放置胰管支架后，胰管管壁甚至能堵塞分支胰管开口，导致分支胰管内胰液排泄不畅，从而诱发高淀粉酶血症及急性胰腺炎的发生。Although the pancreatic duct stent can drain the pancreatic juice in the main pancreatic duct, it can reduce the pressure of the main pancreatic duct. However, the currently used pancreatic duct stents have limited lateral holes on the wall, and there are many pancreatic duct branches, and the lateral holes on the wall are not enough to drain the pancreatic juice in the branched pancreatic ducts. For some patients with no dilatation of the pancreatic duct, after placing the pancreatic duct stent, the wall of the pancreatic duct can even block the opening of the branch pancreatic duct, resulting in poor excretion of pancreatic juice in the branch pancreatic duct, thereby inducing hyperamylaseemia and acute pancreatitis.
