Pancreatic duct stones in patients with chronic pancreatitis:surgical outcomes

BACKGROUND: Pancreatic duct stone (PDS) is a common complication of chronic pancreatitis. Surgery is a common therapeutic option for PDS. In this study we assessed the surgical procedures for PDS in patients with chronic pancreatitis at our hospital. METHOD: Between January 2004 and September 2009, medical records from 35 patients diagnosed with PDS associated with chronic pancreatitis were retrospectively reviewed and the patients were followed up for up to 67 months. RESULTS: The 35 patients underwent ultrasonography, computed tomography, or both, with an overall accuracy rate of 85.7%. Of these patients, 31 underwent the modified Puestow procedure, 2 underwent the Whipple procedure, 1 underwent simple stone removal by duct incision, and 1 underwent pancreatic abscess drainage. Of the 35 patients, 28 were followed up for 4-67 months. There was no postoperative death before discharge or during follow-up. After the modified Puestow procedure, abdominal pain was reduced in patients with complete or incomplete stone clearance (P>0.05). Steatorrhea and diabetes mellitus developed in several patients during a long-term follow-up. CONCLUSIONS: Surgery, especially the modified Puestow procedure, is effective and safe for patients with PDS associated with chronic pancreatitis. Decompression of intraductal pressure rather than complete clearance of all stones predicts postoperative outcome.

Retrospective analysis of 88 patients with pancreatic duct stone

BACKGROUND: Pancreatic duct stone is a rare disease, but there appears to be a rising trend in its incidence in recent years. Its pathogenesis remains unknown. The causes, diagnosis and treatment of pancreatic duct stone are reviewed through a retrospective analysis of the cases treated in our hospital. METHODS: The medical records of 88 patients with pancreatic duct stone treated in West China Hospital, Sichuan University from January 1, 1998 to November 30, 2004 were analyzed retrospectively in terms of clinical characteristics, diagnosis and treatment. RESULTS: Epigastric pain was the most common symptom in the 88 patients with an average age of 45.44 +/- 6.72 years. Various other symptoms were also observed. Eighty-one patients were subjected to B-ultrasonography, 51 to CT, and 47 to magnetic resonance cholangiopancreatography (MRCP). Fifty-six patients (63.64%) were operated on, 25 (28.41%) were treated with Chinese and Western medicine, and 7 (7.95%) abandoned treatment. Chronic pancreatitis was pathologically confirmed in all patients undergoing operation. CONCLUSIONS: B-ultrasonography is the first choice to check for pancreatic duct stone, while MRCP proves instructively useful for the diagnosis and treatment. Chronic pancreatitis is the most important cause of pancreatic duct stone, but whether there is not a direct correlation between stone formation and alcohol abuse needs further study in China. Surgery is the most curative method for pancreatic duct stone patients with severe symptoms or suspected pancreatic carcinoma, while individual treatment is emphasized, and microtraumatic surgery may be a developing option for treating pancreatic stone.

Laparoscopic pancreatic duct incision and stone removal and T-type tube drainage for pancreatic duct stone: A case report and review of literature

To study a more micro-invasive procedure for patients having pancreatic duct stones(PDS).Till now,there has been no report of laparoscopic pancreatic duct incision and stone removal and T-type tube drainage for PDS in the English literature.An 82-year-old man suffered from subxiphoid pain associated with a dilated pancreatic duct(7 mm)containing one stone,but without a mass in the head of the pancreas.Laparoscopic pancreatic duct incision,stone removal,and T-type tube drainage were successfully performed without intraoperative or postoperative complications.An uneventful operation was performed with laparoscopically completed procedures in 160 min.The intraoperative loss of blood was around 50 mL.After patient a discharge on day 11,complete relief from the subxiphoid pain was reported at a follow-up visit 15 mo later.Laparoscopic pancreatic duct incision with stone removal and T-type tube drainage is applicable in carefully selected patients and can be effectively and safely used for the treatment of the abdominal pain of chronic pancreatitis.

Magnetic resonance cholangiopancreatography for the detection of pancreatic duct stones in patients with chronic pancreatitis

AIM:To assess the role of magnetic resonance cholangiopancreatography(MRCP) in detection of pancreatic duct stones(PDS) in patients with chronic pancreatitis(CP).METHODS:Clinical data of 78 CP patients who were treated at the First Affi liated Hospital of Xi'an Jiaotong University(China) between January 2004 and July 2008 were retrospectively analyzed.A predictive model of pancreatic duct stones was established through logistic regression and its effectiveness was verifi ed.Among these patients, MRCP was performed in 60 patients who served as a control group, while 44 patients with a higher predictive value than the entry threshold of the predictive model served as an experimental group.RESULTS:The positive rate of PDS in the 78 patients with CP was 19.2%(15/78).The predictive entry threshold of the predictive model was 5%(P < 0.05).The possibility of existence of PDS could be predicted according to the following 4 indexes:gastrointestinal symptoms, intermittent abdominal pain, diabetes mellitus(DM)/impaired glucose tolerance(IGT) and positive B-mode ultrasound results.The incidence of PDS in the experimental group was higher than that in the control group(P < 0.05).CONCLUSION:MRCP is strongly suggested for the detection of PDS in patients with gastrointestinal symptoms, intermittent abdominal pain, DM/IGT and positive B-mode ultrasound results.

Risk factors for the development of post-endoscopic retrograde cholangiopancreatography pancreatitis in patients with asymptomatic common bile duct stones

BACKGROUND Previous studies have revealed that patients with asymptomatic common bile duct(CBD)stones are at a high risk of developing post-endoscopic retrograde cholangiopancreatography(ERCP)pancreatitis(PEP).However,no studies to date have addressed the risk factors for PEP in patients with asymptomatic CBD stones.AIM To examine the risk factors for PEP in patients with asymptomatic CBD stones.METHODS Using medical records of three institutions in Japan for 6 years,we identified a total of 1135 patients with choledocholithiasis including 967 symptomatic patients and 168 asymptomatic patients with native papilla who underwent therapeutic ERCP.We performed univariate and multivariate analyses to examine the risk factors for PEP in the 168 patients with asymptomatic CBD stones.RESULTS The overall incidence rate of PEP in all the patients with during study period was 4.7%(53/1135).Of the 168 patients with asymptomatic CBD stones,24(14.3%)developed PEP.In univariate analysis,precut sphincterotomy(P=0.009)and biliary balloon sphincter dilation(P=0.043)were significant risk factors for PEP.In multivariate analysis,precut sphincterotomy(P=0.002,95%CI:2.2-27.8,odds ratio=7.7),biliary balloon sphincter dilation(P=0.015,95%CI:1.4-17.3,odds ratio=4.9),and trainee endoscopists(P=0.048,95%CI:1.01-8.1,odds ratio=2.9)were significant risk factors for PEP.CONCLUSION ERCP for asymptomatic CBD stones should be performed by experienced endoscopists.When performing precut sphincterotomy or biliary balloon sphincter dilation in patients with asymptomatic CBD stones,the placement of a prophylactic pancreatic stent is strongly recommended to prevent PEP.

Bedside score predicting retained common bile duct stone in acute biliary pancreatitis

BACKGROUND Retained common bile duct(CBD) stone after an acute episode of biliary pancreatitis is of paramount importance since stone extraction is mandatory.AIM To generate a simple non-invasive score to predict the presence of CBD stone in patients with biliary pancreatitis.METHODS We performed a retrospective study including patients with a diagnosis of biliary pancreatitis. One hundred and fifty-four patients were included. Thirty-three patients(21.5%) were diagnosed with CBD stone by endoscopic ultrasound(US).RESULTS In univariate analysis, age(OR: 1.048, P = 0.0004), aspartate transaminase(OR:1.002, P = 0.0015), alkaline phosphatase(OR: 1.005, P = 0.0005), gamma-glutamyl transferase(OR: 1.003, P = 0.0002) and CBD width by US(OR: 1.187, P = 0.0445)were associated with CBD stone. In multivariate analysis, three parameters were identified to predict CBD stone;age(OR: 1.062, P = 0.0005), gamma-glutamyl transferase level(OR: 1.003, P = 0.0003) and dilated CBD(OR: 3.685, P = 0.027),with area under the curve of 0.8433. We developed a diagnostic score that included the three significant parameters on multivariate analysis, with assignment of weights for each variable according to the co-efficient estimate. A score that ranges from 51.28 to 73.7 has a very high specificity(90%-100%) for CBD stones, while a low score that ranges from 9.16 to 41.04 has a high sensitivity(82%-100%). By performing internal validation, the negative predictive value of the low score group was 93%.CONCLUSION We recommend incorporating this score as an aid for stratifying patients with acute biliary pancreatitis into low or high probability for the presence of CBD stone.

Ampulla dilation with different sized balloons to remove common bile duct stones

AIM:To assess the outcomes of ampulla dilation with different sized balloons to remove common bile duct (CBD) stones.METHODS:Patients (n=208) were divided into five groups based on the largest CBD stone size of < 5,6-8,8-12,12-14,and > 14 mm.Patients underwent limited endoscopic sphincterotomy (EST) alone or limited EST followed by endoscopic papillary balloon dilation with 8,10,12 and 14 mm balloons,such that the size of each balloon did not exceed the size of the CBD.Short-and long-term outcomes,such as post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis,perforation,bleeding,and pneumobilia were compared among the five groups.RESULTS:The overall rate of successful stone removal in all groups was 100%,and all patients were cured.Eight (3.85%) patients had post-ERCP pancreatitis,none had perforations,and 6 (2.9%) had bleeding re-quiring transfusion.There were no significant differences in early complication rates among the five groups.We observed significant correlations between increased balloon size and the short-and long-term rates of postERCP pneumobilia.Post-ERCP pancreatitis and bleeding correlated significantly with age,with post-ERCP pancreatitis occurring more frequently in patients aged < 60 years,and bleeding occurring more frequently in patients aged > 70 years.We observed a significant correlation between patient age and the diameter of the largest CBD stone,with stones > 12 mm occurring more frequently in patients > 60 years old.CONCLUSION:Choosing a balloon size based on the largest stone diameter is safe and effective for removing CBD stones.Balloon size should not exceed 15 mm.

Comparison of endoscopic papillary balloon dilatation and endoscopic sphincterotomy for bile duct stones

Endoscopic treatment for bile duct stones is low-invasive and currently considered as the first choice of the treatment. For the treatment of bile duct stones, papillary treatment is necessary, and the treatments used at the time are broadly classified into two types; endoscopic papillary balloon dilatation where bile duct closing part is dilated with a balloon and endoscopic sphincterotomy(EST) where bile duct closing part is incised. Both procedures have advantages and disadvantages. Golden standard is EST, however, there are patients with difficulty for EST, thus we must select the procedure based on understanding of the characteristics of the procedure, and patient backgrounds.

Is ERCP really necessary in case of suspected spontaneous passage of bile duct stones?

AIM:To investigate the usefulness of magnetic resonance cholangiopancreatography (MRCP) and the need for endoscopic retrograde cholangiopancreatography (ERCP) in cases of suspected spontaneous passage of stones into the common bile duct.METHODS:Thirty-six patients with gallbladder stones were clinically suspected of spontaneous passage of stones into the common bile duct because they presented with clinical symptoms such as abdominal pain and fever,and showed signs of inflammatory reaction and marked rise of hepatobiliary enzymes.These symptoms resolved and they showed normalized values of blood biochemical parameters after conservative treatment without evidence of stones in the common bile duct on MRCP.All these patients were subjected to ERCP within 3 d of MRCP to check for the presence of stones.RESULTS:No stones were detected by ERCP in any patient,confi rming the results of MRCP.CONCLUSION:When clinical symptoms improve,blood biochemical parameters have normalized,and MRCP shows there are no stones in the common bile duct,it can be considered the stone has spontaneously passed and thus ERCP is not necessary.

Complications of common bile duct stones: A risk factors analysis

Background: The latest guidelines recommended that common bile duct stones(CBDSs) should be removed, preferably endoscopically, regardless of the presence of symptoms or complications. However, the removal of CBDSs may not be feasible in very old patients or those with co-morbidities. In these cases, it is important to understand the risk factors for the development of CBDSs-related complications to decide whether or not to treat high-risk patients. Herein, we aimed to identify the risk factors for the development of complications after the diagnosis of CBDSs. Methods: The medical records of patients with CBDSs between October 2005 and September 2019 were retrospectively analyzed. All patients with radiologically-diagnosed CBDSs, including those who received treatment and those who did not, were analyzed. Results: A total of 634 patients were included and 95(15.0%) patients had CBDS-related complications during the mean follow-up period of 32.6 months. Forty-four(6.9%) high-risk patients remained asymptomatic and did not receive treatment during the follow-up period. In multivariate analyses, size of CBDSs ≥ 5 mm and no treatment within 30 days were independent risk factors for the development of complications. The spontaneous passage of CBDSs was proved radiologically in 9 out of 81(11.1%) patients within 30 days. Conclusions: It is recommended treating CBDSs within 30 days from the diagnosis, even in high-risk patients, especially if the size is larger than 5 mm.

Pancreatico-biliary endoscopic ultrasound:A systematic review of the levels of evidence,performance and outcomes

Our aim was to record pancreaticobiliary endoscopic ultrasound(EUS) literature of the past 3 decades and evaluate its role based on a critical appraisal of published studies according to levels of evidence(LE).Original research articles(randomized controlled trials,prospective and retrospective studies),meta-analyses,reviews and surveys pertinent to gastrointestinal EUS were included.All articles published until September 2011 were retrieved from PubMed and classified according to specific disease entities,anatomical subdivisions and therapeutic applications of EUS.The North of England evidencebased guidelines were used to determine LE.A total of 1089 pertinent articles were reviewed.Published research focused primarily on solid pancreatic neoplasms,followed by disorders of the extrahepatic biliary tree,pancreatic cystic lesions,therapeutic-interventional EUS,chronic and acute pancreatitis.A uniform observation in all six categories of articles was the predominance of LE Ⅲ studies followed by LE Ⅳ,Ⅱb,Ⅱa,Ⅰb and Ⅰ a,in descending order.EUS remains the most accurate method for detecting small(< 3 cm) pancreatic tumors,ampullary neoplasms and small(< 4 mm) bile duct stones,and the best test to define vascular invasion in pancreatic and peri-ampullary neoplasms.Detailed EUS imaging,along with biochemical and molecular cyst fluid analysis,improve the differentiation of pancreatic cysts and help predict their malignant potential.Early diagnosis of chronic pancreatitis appears feasible and reliable.Novel imaging techniques(contrast-enhanced EUS,elastography) seem promising for the evaluation of pancreatic cancer and autoimmune pancreatitis.Therapeutic applications currently involve pancreaticobiliary drainage and targeted fine needle injection-guided antitumor therapy.Despite the ongoing development of extra-corporeal imaging modalities,such as computed tomography,magnetic resonance imaging,and positron emission tomography,EUS still holds a leading role in the investigation of the pancreaticobiliary area.The major challenge of EUS evolution is its expanding therapeutic potential towards an effective and minimally invasive management of complex pancreaticobiliary disorders.

Endoscopic retrograde cholangiopancreatography with rendezvous cannulation reduces pancreatic injury

AIM:To examine whether rendezvous endoscopic retrograde cholangiopancreatography(ERCP)is associated with less pancreatic damage,measured as leakage of proenzymes,than conventional ERCP.METHODS:Patients(n=122)with symptomatic gallstone disease,intact papilla and no ongoing inflammation,were prospectively enrolled in this case-controldesigned study.Eighty-one patients were subjected to laparoscopic cholecystectomy and if intraoperative cholangiography suggested common bile duct stones(CBDS),rendezvous ERCP was performed intraoperatively(n=40).Patients with a negative cholangiogram constituted the control group(n=41).Another 41 patients with CBDS,not subjected to surgery,underwent conventional ERCP.Pancreatic proenzymes,procarboxypeptidase B and trypsinogen-2 levels in plasma,were analysed at 0,4,8 and 24 h.The proenzymes were determined in-house with a double-antibody enzyme linked immunosorbent assay.Pancreatic amylase was measured by an enzymatic colourimetric modular analyser with the manufacturer’s reagents.All samples were blinded at analysis.RESULTS:Post ERCP pancreatitis(PEP)occurred in3/41(7%)of the patients cannulated with conventional ERCP and none in the rendezvous group.Increased serum levels indicating pancreatic leakage were significantly higher in the conventional ERCP group compared with the rendezvous ERCP group regarding pancreatic amylase levels in the 4-and 8-h samples(P=0.0015;P=0.03),procarboxypeptidase B in the4-and 8-h samples(P<0.0001;P<0.0001)and trypsinogen-2 in the 24-hour samples(P=0.03).No differences in these markers were observed in patients treated with rendezvous cannulation technique compared with patients that underwent cholecystectomy alone(control group).Post procedural concentrations of pancreatic amylase and procarboxypeptidase B were significantly correlated with pancreatic duct cannulation and opacification.CONCLUSION:Rendezvous ERCP reduces pancreatic enzyme leakage compared with conventional ERCP cannulation technique.Thus,laparo-endoscopic technique can be recommended with the ambition to minimise the risk for post ERCP pancreatitis.

Role of pancreatoscopy in management of pancreatic disease:A systematic review

BACKGROUND Per-oral pancreatoscopy(POP) plays a role in the diagnosis and therapy of pancreatic diseases. With recent technological advances, there has been renewed interest in this modality.AIM To evaluate the efficacy and safety of POP in management of pancreatic stone disease and pancreatic ductal neoplasia.METHODS To determine the safety and efficacy of POP in the management of pancreatic diseases, a systematic search was conducted in MEDLINE, EMBASE and Ovid.Articles in languages other than English and case reports were excluded. All published case series were eligible. Data specific to POP were extracted from studies, which combined cholangiopancreatoscopy. Ten studies were included in the analysis of POP therapy for pancreatic stone disease, and 15 case series satisfied the criteria for inclusion for the role of POP in the management of pancreatic ductal neoplasia. The examined data were subcategorized according to adjunctive modalities, such as direct tissue sampling, cytology, the role of intraoperative POP, intraductal ultrasound(IDUS) and POP combined with image-enhancing technology.RESULTS The success rate for complete ductal stone clearance ranged from 37.5%-100%.Factors associated with failure included the presence of strictures, multiple stonesand the inability to visualize the target area. Although direct visualization can identify malignant and premalignant conditions, there is significant overlap with benign diseases. Visually-directed biopsies provide a high degree of accuracy,and represent a unique approach for tissue acquisition in patients with ductal abnormalities. Addition of pancreatic fluid cytology increases diagnostic yield for indeterminate lesions. Protrusions larger than 3 mm noted on IDUS are significantly more likely to be associated with malignancy. The rate of adverse events associated with POP ranged from 0%-35%.CONCLUSION Current evidence supports wider adoption of pancreatoscopy, as it is safe and effective. Improved patient selection and utilization of novel technologies may further enhance its role in managing pancreatic disease.

老年胆囊结石合并胆总管结石患者腹腔镜微创取石术后发生胰腺炎的危险因素及其预测效能

Role of endoscopic ultrasound in idiopathic pancreatitis

Recurrent acute pancreatitis(RAP) is defined based on the occurrence of two or more episodes of acute pancreatitis. The initial evaluation fails to detect the cause of RAP in 10%-30% of patients, whose condition is classified as idiopathic RAP(IRAP). Idiopathic acute pancreatitis(IAP) is a diagnostic challenge for gastroenterologists. In view of associated morbidity and mortality, it is important to determine the aetiology of pancreatitis to provide early treatment and prevent recurrence. Endoscopic ultrasound(EUS) is an investigation of choice for imaging of pancreas and biliary tract. In view of high diagnostic accuracy and safety of EUS, a EUS based management strategy appears to be a reasonable approach for evaluation of patients with a single/recurrent idiopathic pancreatitis. The most common diagnoses by EUS in IAP is biliary tract disease. The present review aims to discuss the role of EUS in the clinical management and diagnosis of patients with IAP. It elaborates the diagnostic approach to IAP in relation to EUS and other different modalities. Controversial issues in IAP like when to perform EUS, whether to perform after first episode or recurrent episodes, comparison among different investigations and the latest evidence significance are detailed.

Balloon dilation itself may not be a major determinant of post-endoscopic retrograde cholangiopancreatography pancreatitis

Endoscopic retrograde cholangiopancreatography (ERCP) is the essential first modality for common bile duct (CBD) stone therapy. The conventional endoscopic treatment for CBD stones is stone removal after endoscopic sphincterotomy (EST). Stone removal after papillary stretching using balloon dilation instead of the conventional method has been widely adopted. There are many reports regarding endoscopic papillary balloon dilation (EPBD) utilizing a small balloon (&#x0003c; 10 mm) instead of EST for the removal of small CBD stones. In contrast, two cases of mortality due to post-ERCP pancreatitis (PEP) were reported after an EPBD clinical trial in the Western world, and the psychological barrier caused by these incidences hinders the use of this technique in Western countries. Endoscopic papillar large balloon dilation (EPLBD), which is used to treat large CBD stones, was not widely adopted when first introduced due to concerns about perforation and severe pancreatitis from the use of a large balloon (12-20 mm). However, as experience with this procedure accumulates, the occurrence of PEP with EPLBD is confirmed to be much lower than with EPBD. This report reviews whether EPBD and EPLBD, two procedures that use balloon dilation but differ in terms of indications and concept, contribute to the occurrence of PEP.

双导丝法联合胰管支架置入术在胆总管结石ERCP中的应用研究

目的研究双导丝法联合胰管支架置入术在胆总管结石内镜逆行胰胆管造影术(ERCP)中的应用效果。方法回顾性分析本院2020年1月至2022年1月期间接诊的106例胆总管结石患者的临床资料。根据不同的治疗方案将其分为研究组与对照组各53例。两组患者均行ERCP,对照组采用传统胆管选择性插管进行治疗,研究组采用双导丝法联合胰管支架置入术进行治疗。记录并比较两组患者的插管成功率、手术时间、插管时间、术后进食时间、住院时间及术后并发症发生率。结果研究组患者的插管成功率为94.34%,明显高于对照组患者的77.36%(P<0.05);两组患者的术后进食时间相比(P>0.05),研究组患者的手术时间、插管时间、住院时间均明显短于对照组(均P<0.05);对照组与研究组患者术后并发症发生率分别为15.09%、7.55%,两组差异无统计学意义(P>0.05)。结论双导丝法联合胰管支架置入术在胆总管结石ERCP中的应用效果显著,能有效地提高患者的插管率,缩短手术时间、插管时间及住院时间,且安全性高,具有临床应用价值。

基于损伤控制理念的胆道疾病处理与治疗

急性胆道疾病严重威胁病人生命。病情危重病人的急诊手术治疗预后较差。我科整合多学科优势,总结经验,对胆道急症病人采取分阶段处理,大大改善预后。对于急性重症胆囊炎病人,先行经皮经肝胆囊穿刺引流缓解梗阻,择期手术治疗,显著降低胆道损伤发生率、术后死亡率和重症监护病房入住率。对于胆囊管通畅的胆源性胰腺炎病人,先行经皮经肝胆囊穿刺引流缓解胰腺炎症状,择期行内镜乳头括约肌切开或腹腔镜胆总管探查术,更安全。对于胆管扩张的肝内外胆管结石病人,先行内镜鼻胆管引流或经皮经肝胆管穿刺引流解除梗阻,大大提高生存率。对于胆道恶性肿瘤伴黄疸病人,应用经皮经肝胆管穿刺引流或内镜鼻胆管引流尽早减黄,之后经皮经肝胆管穿刺引流置入支架以达到延长生命的目的。
