ABSTRACT
La Sociedad Europea de Endoscopia Gastrointestinal (ESGE) define "canulación difícil" como aquella en la que se realizan más de 5 intentos, se exceden 5 minutos, o se produce canulación inadvertida del conducto pancreático 2 o más veces (criterios 5-5-2), recomendando estos puntos de corte para realizar técnicas avanzadas de canulación y disminuir la tasa de eventos adversos post CPRE. Nuestro objetivo fue evaluar el rendimiento de los criterios 5-5-2 y su asociación con complicaciones post CPRE en un hospital de referencia de Perú. Realizamos un estudio analítico prospectivo de casos y controles en el que se incluyó 120 pacientes a los que se realizó CPRE. El grupo casos estuvo formado por 30 pacientes que cumplieron al menos uno de los criterios 5-5-2 y el grupo controles por 90 pacientes sin ninguno de estos criterios. Se comparó el desarrollo de complicaciones en cada grupo y su asociación con cada uno de los criterios 5-5-2. Las complicaciones presentadas fueron: pancreatitis post CPRE (6,6% en el grupo casos vs 3,3% en el grupo controles), sangrado (3,3% controles vs 0% casos) y perforación (1,1% controles vs 0 % casos); sin observar diferencia estadísticamente significativa. El criterio de 2 o más ingresos inadvertidos al conducto pancreático presentó asociación significativa (OR= 10,29, IC: 1,47-71,98; p= 0,005) con el desarrollo de pancreatitis post CPRE. Los criterios 5 minutos y 5 intentos no se asociaron a complicaciones post CPRE. En conclusión, el más relevante de los criterios 5-5-2 fue el ingreso inadvertido al conducto pancreático en 2 o más ocasiones, mostrando asociación por sí solo con pancreatitis post CPRE. Los criterios tiempo y número de intentos podrían ampliarse con cautela sin aumentar la tasa de complicaciones post CPRE.
The European Society for Gastrointestinal Endoscopy (ESGE) defines "difficult biliary cannulation" by the presence of one or more of the following: more than 5 contacts with the papilla, more than 5 minutes attempting to cannulate, or inadvertent cannulation of the pancreatic duct in 2 or more times (5-5-2 criteria), recommending these cut-off points to perform advanced cannulation techniques in order to reduce the rate of post-ERCP adverse events. Our objective was to evaluate the performance of the 5-5-2 criteria and their association with post-ERCP complications in a reference hospital in Peru. We performed a prospective analytical case-control study and 120 patients who underwent ERCP were enrolled. The case group included 30 patients who met at least one of the 5-5-2 criteria and the control group included 90 patients without any of these criteria. The ERCP- related complications in both groups and their association with each of the 5-5-2 criteria were compared. The ERCP-related complications that occurred were post-ERCP pancreatitis (6.6% in the case group vs. 3.3% in the control group), bleeding (3.3% controls vs. 0% cases) and perforation (1.1% controls vs. 0% cases); no statistically significant differences were observed. The criterion of 2 or more unintended cannulations to the pancreatic duct showed a significant association (OR= 10.29, CI: 1.47-71.98; p= 0.005) with the incidence of post-ERCP pancreatitis. The criteria 5 minutes and 5 attempts were not associated with post-ERCP complications. In conclusion, among 5-5-2 criteria only the unintended cannulation of 2 or more times into the pancreatic duct was associated with an increased risk of post-ERC pancreatitis. The time and number of attempts criteria could be cautiously expanded without increasing the rate of post-ERCP complications.
ABSTRACT
La disfunción del esfínter de Oddi (DEO) es una patología poco frecuente que debe ser considerada en el diagnóstico diferencial de pacientes con episodios de dolor biliar o pancreatitis aguda recurrente y antecedente de colecistectomía. Generalmente son pacientes con múltiples consultas, en los cuales la patología ha afectado considerablemente su calidad de vida. El diagnóstico se sustenta en la clínica, los marcadores serológicos y los medios diagnósticos de soporte, que se solicitan según el componente esfinteriano sospechado. El tratamiento con mayor eficacia es la esfinterotomía endoscópica. El uso de prótesis es aceptado, pero discutido. Se presenta el caso de un paciente masculino en la cuarta década de la vida que consultó por múltiples episodios de pancreatitis aguda recurrente con estudios de etiología que sospecharon disfunción del esfínter de Oddi pancreático y quien fue llevado a manejo endoscópico, con mejoría de su cuadro clínico.
Sphincter of Oddi Dysfunction (SOD) is a rare pathology that should be considered in the differential diagnosis of patients with biliary pain episodes or recurrent acute pancreatitis and a background of cholecystectomy. Generally, these are patients with multiple consultations where this pathology has considerably affected their quality of life. Diagnosis is based on clinical findings, serological markers and supporting diagnostic tests requested according to the suspected sphincteric component. The most effective treatment is endoscopic sphincterotomy. The use of prosthesis is accepted but debated. We present the case of a male patient in his forties who consulted for multiple episodes of recurrent acute pancreatitis with etiology studies suspecting dysfunction of the pancreatic sphincter of Oddi and who was taken to endoscopic management with improvement of his clinical picture.
ABSTRACT
Objective To investigate whether endoscopic ultrasonography (EUS) can be an alternative method for diagnostic endoscopic retrograde cholangiopancreatography (ERCP) by comparing the ability of EUS versus CT and transabdominal ultrasonography (TUS) in the diagnosis of muddy stones of the common bile duct. Methods A prospective study was conducted for 53 patients suspected of muddy stones of the common bile duct who attended Nanxishan Hospital of Guangxi Zhuang Autonomous Region from July 2019 to December 2021, and all patients underwent EUS, TUS, and CT before ERCP. With ERCP and endoscopic sphincterotomy (EST) for removing muddy stones of the common bile duct as the gold standard for the diagnosis of muddy stones of the common bile duct, EUS, TUS, and CT were compared in terms of their ability to display the muddy stones of the common bile duct. The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups. Results In the 53 patients, EUS, TUS, and CT had a positive rate of 88.68%, 50.94%, and 62.26%, respectively, in detecting muddy stones of the common bile duct. As for the positive results confirmed by EST under ERCP, EUS had a sensitivity of 93.75%, a specificity of 60.00%, and an accuracy of 90.57% in detecting muddy stones of the common bile duct, while TUS had a sensitivity of 56.25%, a specificity of 100.00%, and an accuracy of 60.38% and CT had a sensitivity of 66.67%, a specificity of 80.00%, and an accuracy of 67.92%. There was a significant difference between EUS and CT in the accuracy in detecting muddy stones of the common bile duct ( χ 2 =8.26, P =0.004), and there was also a significant difference in diagnostic accuracy between EUS and TUS ( χ 2 =13.05, P < 0.001). Conclusion EUS is more accurate than TUS and CT in the diagnosis of muddy stones of the common bile duct, and instead of ERCP, EUS is thus recommended for suspected muddy stones of the common bile duct when TUS and CT fail to identify the lesions in clinical practice, so as to make a confirmed diagnosis and reduce related costs and complications.
ABSTRACT
Los abscesos hepáticos son colecciones supurativas encapsuladas dentro del parénquima hepático, las cuales generalmente se encuentran infectadas por bacterias. Se forman por diferentes mecanismos, una de ellas es la secundaria a la infección de las vías biliares, colangitis aguda, la misma que en su evolución natural puede progresar a una infección severa e incluso a sepsis o choque séptico y es por ello que requiere un diagnóstico y tratamiento adecuados. La litiasis biliar puede complicarse con colangitis aguda tras la obstrucción al flujo de salida de la bilis con posterior infección, generalmente bacteriana, no solo del árbol biliar sino también del parénquima hepático. Se presenta el caso clínico de una paciente mujer joven que cursó con microabscesos hepáticos colangiolares tras un evento de coledocolitiasis no tratado oportunamente.
Hepatic abscesses are suppurative collections encapsulated within the liver parenchyma, which are generally infected by bacteria. They are formed by different mechanisms, one of them is secondary to bile duct infection, acute cholangitis, which in its natural history can progress to severe infection and even sepsis or septic shock and that is why it requires a proper diagnosis and treatment. Gallstones can be complicated by acute cholangitis after bile outflow obstruction with subsequent infection, usually bacterial, not only of the biliary tree but also of the liver parenchyma. We present the clinical case of a young female patient who presented with cholangiolar hepatic microabscesses after an event of choledocholithiasis not treated in a timely manner.
ABSTRACT
ObjectiveTo investigate the efficacy and safety of endoscopic retrograde cholangiopancreatography （ERCP） during pregnancy and puerperium through a comparative analysis. MethodsA retrospective analysis was performed for the clinical data of 22 patients in pregnancy and 39 patients in puerperium who received ERCP in Digestive Endoscopy Center of The First Affiliated Hospital of Nanchang University from January 2007 to August 2022. The two groups of patients were compared in terms of baseline data， diagnosis during ERCP， interventions， laboratory results before and after ERCP， post-ERCP complications， and delivery and fetal outcomes. The independent-samples t test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsThere were no significant differences between the patients in pregnancy and those in puerperium in all baseline data （all P>0.05） except the rate of CT examination （22.73% vs 58.97%， χ2=7.44， P=0.006）. During the ERCP procedure， compared with the patients in puerperium， the patients in pregnancy had a significantly lower proportion of the patients who underwent biliary stone extraction or endoscopic papillary balloon dilation （χ2=4.007 and 4.315， both P<0.05） and a significantly higher proportion of the patients who did not receive X-ray fluoroscopy （χ2=12.103， P=0.001）. After ERCP， both groups had significant improvements in white blood cell count， total bilirubin， direct bilirubin， alanine aminotransferase， and aspartate aminotransferase （all P<0.05）. The overall incidence rate of post-ERCP complications was 7.04% （5/71） for all patients， with post-ERCP biliary infection as the most common complication （3/71，4.23%）， and there was no significant difference in the incidence rate of post-ERCP complications between the two groups （P>0.05）. As for delivery and fetal outcomes， compared with the patients in puerperium， the patients in pregnancy had a significantly higher proportion of patients with early termination of pregnancy （50.00% vs 0，χ2=20.528， P<0.001） and a significantly lower proportion of patients with cesarean section （36.36% vs 76.92%， χ2=4.756， P=0.029）. There were no significant differences in the incidence rates of adverse events such as abnormal fetal development and stillbirth between the two groups （P>0.05）. ConclusionWith strict control of ERCP indications and timing， ERCP is effective and relatively safe in both pregnancy and puerperium and has a comparable incidence rate of post-ERCP complications to that in the general population， with relatively good delivery and fetal outcomes.
ABSTRACT
Although hemorrhage after endoscopic retrograde cholangiopancreatography （ERCP） is mostly mild and self－limited， sometimes blood transfusion and endoscopic hemostasis are still needed. However， rebleeding may occur after conventional endoscopic hemostasis and thus requires interventional vascular embolization or surgical intervention， which might significantly increase the risk of death associated with post－ERCP bleeding. This article discusses the risk factors for post－ERCP bleeding， including disease－specific factors， patient－related factors， and operation－related factors， and elaborates on different measures for the prevention and treatment of post－ERCP bleeding， so as to provide a reference for identifying the high－risk population for bleeding and developing precise surgical strategies in clinical practice.
ABSTRACT
Objective:To explore the efficacy of the combination of radiofrequency ablation(RFA) and endoscopic metal stent in the treatment of patients with unresectable cholangiocarcinoma.Methods:From January 3, 2012 to June 30, 2019, at the Department of Endoscopic of the Third Affiliated Hospital of Naval Medical University, the clinical data of 44 patients with unresectable cholangiocarcinoma who were treated by the combination of RFA and endoscopic metal stent were retrospectively collected, which included age, gender, location of cholangiocarcinoma(hilar cholangiocarcinoma and distal cholangiocarcinoma), etc. Postoperative evaluation was conducted based on the follow-up, including clinical success rate, postoperative complication rate, time of stent patency and overall survival time (OS). The Kaplan-Meier method and log-rank test were used to analyze the difference of OS between patients with hilar cholangiocarcinoma and distal cholangiocarcinoma. Mann-Whitney U test was used for statistical analysis. Results:The age of the 44 patients with cholangiocarcinoma was (70.3±11.6) years old, with 20 males (45.5%). There were 22 patients (50.0%) with hilar cholangiocarcinoma and 22 patients (50.0%) with distal cholangiocarcinoma. The clinical success rate of 44 patients was 93.2%(41/44). A total of 5 patients(11.4%) had postoperative complications, which were all improved by appropriate treatment. The median time of follow-up of the 44 patient was 9.2 months(ranged from 3.1 to 57.6 months), the median time of stent patency was 7.0 months (ranged from 5.8 to 8.2 months). Thirty-two patients (72.7%) died during the follow-up, and the median OS was 10.9 months(ranged from 9.0 to 12.8 months). The median OS of patients with hilar cholangiocarcinoma was 7.8 months(ranged from 4.6 to 11.0 months) and that of patients with distal cholangiocarcinoma was 12.5 months(ranged from 5.7 to 19.4 months), and there was no statistically significant difference( P>0.05). Conclusion:RFA combined with endoscopic metal stent is safe and effective in the treatment of patients with unresectable cholangiocarcinoma.
ABSTRACT
Objective:To investigate the influence of liver drainage volume on overall survival time in patients with unresectable malignant hilar bile duct obstruction.Methods:Data of 633 patients with unresectable malignant hilar bile duct obstruction (BismuthⅡ-Ⅳ) who underwent endoscopic stent drainage in 3 endoscopy centers from January 2002 to May 2019 were retrospectively analyzed. Main observation indicators included clinical success rate, stent patency, overall survival, the effective liver drainage volume, and complication incidence.Results:The clinical success rates of patients with liver drainage volume <30%, 30%-50%, and >50% were 56.8% (25/44), 77.3% (201/260) and 84.2% (277/329) respectively. The incidences of early cholangitis were 31.8% (14/44), 18.8% (49/260) and 16.1% (53/329). The median stent patency time was 4.5 (95% CI: 1.8-7.2) months, 5.6 (95% CI: 5.0-6.2) months and 6.6 (95% CI: 5.2-8.0) months. The overall survival time was 2.4 (95% CI: 1.8-3.0) months, 4.0 (95% CI: 3.4-4.6) months and 4.9 (95% CI:4.4-5.4) months, respectively. The clinical success rate ( χ 2=8.28, P=0.012), median stent patency period ( χ 2=18.87, P=0.015) and overall survival time ( χ 2=6.93, P=0.024) of 30%-50% liver drainage volume group were significantly higher than those of <30% group. Further multivariate cox regression analysis showed that the disease type (hepatocellular carcinoma VS hilar cholangiocarcinoma: HR=1.50, 95% CI:1.18-1.91, P=0.001; gallbladder carcinoma VS hilar cholangiocarcinoma: HR=1.45, 95% CI:1.14-1.85, P=0.002; metastatic cholangiocarcinoma VS hilar cholangiocarcinoma: HR=1.48, 95% CI:1.08-2.04, P=0.015), bilirubin level >200 μmol/L ( HR=1.35, 95% CI:1.14-1.60, P<0.001),metal stents ( HR=0.67, 95% CI:0.56-0.79, P<0.001), liver drainage volume (volume 30%-50% VS <30%: HR=0.64, 95% CI: 0.45-0.90, P=0.010; volume>50% VS <30%: HR=0.58, 95% CI:0.41-0.81, P=0.002) and anti-tumor therapy ( HR=0.51, 95% CI:0.42-0.61, P<0.001) were independent predictors for overall survival time of patients with unresectable malignant hilar bile duct obstruction. Conclusion:When endoscopic stent drainage is performed for patients with unresectable malignant hilar bile duct obstruction, at least 30% liver volume is required for better overall survival. In addition, the use of metal stent drainage and anti-tumor therapy may increase survival benefits.
ABSTRACT
Objective:To investigate the risk factors for acute cholangitis after endoscopic retrograde cholangiopancreatography (ERCP) and to construct its nomogram.Methods:Clinical data of patients who underwent ERCP for common bile duct stones in the First Hospital of Lanzhou University from January 2014 to December 2019 were retrospectively analyzed. A total of 95 patients with acute cholangitis after the operation (the acute cholangitis group) were included and 285 patients without acute cholangitis after the operation (the non-acute cholangitis group) were selected by random sampling at 1∶3 via the software. Logistic regression analysis was used to evaluate the risk factors for acute cholangitis after ERCP. A nomogram model was established to predict the incidence of acute cholangitis after ERCP based on the results of multivariate analysis.Results:Univariate analysis showed that there were significant differences in age, combination with diabetes, levels of alanine aminotransferase, alkaline phosphatase and glucose, roughness in gallbladder wall, bile duct diameter, stenosis in lower bile duct, proportion of patients who underwent endoscopic retrograde biliary drainage and endoscopic nasobiliary drainage between the two groups ( P<0.05). Logistic multivariate regression analysis showed that advanced age ( OR=1.108, 95% CI:1.079-1.138, P<0.001), combination with diabetes ( OR=4.524, 95% CI:1.299-15.758, P=0.018), roughness in gallbladder wall ( OR=2.495, 95% CI:1.106-5.630, P=0.028), increased bile duct diameter ( OR=1.303, 95% CI:1.181-1.437, P<0.001), and stenosis in lower bile duct ( OR=4.192, 95% CI:2.508-7.005, P<0.001) were independent risk factors for acute cholangitis after ERCP. Based on the results of multivariate analysis, the nomogram of acute cholangitis after ERCP was established. The area under the receiver operator characteristic curve was 0.887. Conclusion:Advanced age, combination with diabetes, rough gallbladder wall, increased diameter of bile duct and stenosis in lower bile duct are independent risk factors for acute cholangitis after ERCP. Clinicians can make clinical intervention based on the nomogram of risk factors above to improve the prognosis of patients.
ABSTRACT
Objective:To explore the preventive effects of pancreatic duct stent combined with rectal administration of indomethacin suppository for post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) after difficult bile duct intubation during endoscopic retrograde cholangiopancreatography (ERCP).Methods:From January 2019 to December 2021, patients with biliary and pancreatic diseases undergoing ERCP in Hangzhou Hospital Affiliated to Nanjing Medical University were given 100 mg indomethacin suppository to anal canal 30 minutes before the operation. And those with difficult bile duct intubation during the operation ( n=204) were included in this study. According to the random number table, they were divided into the combination group (implanted with pancreatic duct stent during the operation, n=104) and the indomethacin group (not implanted with stent, n=100). The incidences of hyperamylasemia and PEP were compared between the two groups. Results:The incidences of postoperative hyperamylasemia [21.2% (22/104) VS 34.0% (34/100), χ2=4.22, P=0.040] and PEP [14.4% (15/104) VS 32.0% (32/100), χ2=8.88, P=0.003] in the combination group were significantly lower than those in the indomethacin group. There was no significant difference in the incidence of severe PEP between the two groups [1.0% (1/104) VS 1.0% (1/100), χ2=0.001, P=0.978]. Conclusion:Compared with rectal administration of indomethacin suppository alone, the incidences of hyperamylasemia and PEP after difficult bile duct intubation during ERCP can be further reduced when it is combined with pancreatic duct stent placement.
ABSTRACT
Objective:To evaluate the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) after pancreaticoduodenectomy and endoscopic selection strategies.Methods:Clinical data of 34 patients treated with ERCP after pancreaticoduodenectomy at the Endoscopic Center of the First Affiliated Hospital of Air Force Medical University from January 2013 to December 2021 were retrospectively analyzed. The success rates of endoscopic insertion, diagnosis, treatment and ERCP, and the incidence of adverse events were analyzed.Results:Fifty ERCP treatments were performed in 34 patients. The success rates of endoscopic insertion, diagnosis, treatment, and ERCP after pancreaticoduodenectomy were 92.0% (46/50), 93.5% (43/46), 88.4% (38/43) and 76.0% (38/50), respectively. The success rates of ERCP assisted with colonoscope and balloon-assisted enterosocpe were 76.0% (19/25) and 75.0% (18/24), respectively. There were 3 adverse events, including 1 case of anastomotic mucosa tear during surgery, 1 case of cardiopulmonary arrest and 1 case of postoperative cholangitis.Conclusion:ERCP is effective and safe after pancreaticoduodenectomy in general. ERCP assisted with colonoscope and balloon-assisted colonoscope shows similar success rate after pancreaticoduodenectomy.
ABSTRACT
Objective:To compare the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) assisted with colonoscope and enteroscope in patients with history of Roux-en-Y anastomosis.Methods:A retrospective study was performed on the data of 70 patients who underwent ERCP assisted with standard colonoscope or single balloon enteroscope after Roux-en-Y reconstruction in Hangzhou Hospital Affiliated to Nanjing Medical University from January 2017 to December 2020. Patients were divided into the standard colonoscopy group ( n=43) and the single balloon enteroscopy group ( n=27) according to endoscopy. The success rates of insertion, intubation and ERCP, and incidence of complications were compared. Results:A total of 81 ERCP procedures were performed in 70 patients. The insertion success rates of the standard colonoscopy group and the single balloon enteroscopy group were 91.8% (45/49) and 78.1% (25/32), respectively, showing no significant difference ( χ2=2.04, P=0.153). The success rates of primitive papilla intubation in the two groups were 74.1% (20/27) and 1/6, showing significant difference ( P=0.016). The ERCP success rates of the standard colonoscopy group and the single balloon enteroscopy group were 75.5% (37/49) and 59.4% (19/32), showing no significant difference ( χ2=2.36, P=0.124). The post operative complication incidences of the standard colonoscopy group and the single balloon enteroscopy group were 4.1% (2/49) and 9.4% (3/32), showing no significant difference ( χ2=0.25, P=0.620). Conclusion:ERCP assisted with standard colonoscope and single balloon enteroscope is safe and effective in patients after Roux-en-Y anastomosis. Standard colonoscopic ERCP can become an endoscopy solution for patients with biliary tract disease after Roux-en-Y reconstruction.
ABSTRACT
Objective:To investigate the application value of endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis and treatment of pancreaticobiliary maljunction (PBM) in children.Methods:The clinical data of 77 PBM children who underwent ERCP in General Surgery Department of Children's Hospital affiliated to Nanjing Medical University between January 2018 and December 2021 were retrospectively evaluated. Clinical characteristics, classification and post-operative nursing interventions were summarized, and vital signs, changes of biochemical markers and the occurrence of postoperative complications were compared and recorded.Results:77 patients were classified according to Japanese Study Group on Pancreaticobiliary Maljunction (JSGPM), including 34 patients with type A, 18 patients with type B, 21 patients with type C, and 4 patients with type D. There were 68 patients with congenital bile duct dilation and 9 patients without congenital bile duct dialtion. 92 ERCP procedures were performed under general anesthesia, and 91 cases were successful with a success rate of 98.91%. Among these cases, including 7 cases of endoscopic sphincterotomy, 28 cases of endoscopic balloon dilation of the nipple, 22 cases of endoscopic probe dilation, 22 cases of endoscopic stone removal by balloon or basket, 35 cases of endoscopic retrograde biliary stent drainage, 4 cases of endoscopic pancreatic duct drainage, 18 cases of endoscopic nasobiliary drainage, 2 cases of endoscopic nasobiliary drainage, and 14 cases of biliary stent removal. In 77 children with PBM, body temperature, FLACC score, and laboratory-related biochemical indexes including direct bilirubin, serum amylase, ALT, AST and CGT decreased significantly after ERCP, and all the differences were statistically significant (all P value <0.001). The incidence of postoperative complications was 15.38%(14/91), including hyperamylasemia in 9 cases (9.89%) and abdominal pain in 5 cases (5.49%). Conclusions:ERCP is safe and effective in the treatment of abnormal confluence of pancreatic duct in children.
ABSTRACT
Iatrogenic bile duct injury (IBDI) refers to bile duct injury accidentally caused by medical factors such as surgical operation or other invasive operations during treatment. With the gradual maturity of surgical operation and minimally invasive techniques, the treatment of bile duct injury now includes endoscopic treatment, bile duct jejunum Roux-en-Y anastomosis, bile duct end-to-end anastomosis, hepatectomy, and liver transplantation. For IBDI, the selection of reasonable and effective treatment methods is currently an important and difficult issue in biliary surgery. Through a systematic review of the literature on the treatment of IBDI, this article analyzes and summarizes the different treatment modalities for IBDI.
ABSTRACT
Cholecystocholedocholithiasis is a common disease worldwide; however, there is still no consensus regarding a gold standard therapy for its management. Nowadays, the preferred method is a "two-step" process, starting with an endoscopic common bile duct (CBD) stone extraction (endoscopic retrograde cholangiopancreatography [ERCP]) followed by a laparoscopic cholecystectomy (LC). Nevertheless, this "two-step" approach has shown some difficulties over time (i.e., need for two hospital admissions, need of at least two anesthesia inductions, higher rate of post-procedural pancreatitis, longer hospitalizations and thus, increased costs). On the other hand, the laparo-endoscopic rendezvous (LER), which is a simultaneous combined procedure for removing the gallbladder laparoscopically and clearing the CBD endoscopically, is another valid treatment modality that involves a "single-step" resolution of cholecystocholedocholithiasis applying a multidisciplinary approach of the patient. The aim of this study was to present our initial outcomes. We retrospectively analyzed eleven patients who consecutively underwent LER at our institution from May 2017 to March 2022. The patients' mean age was 50.6 years old (range, 34 - 68) and most were male 54.5% (6/11). LER successfully achieved CBD stone clearance in 90.9% (10/11) of the cases. Post-LER pancreatitis was not recorded in any case. Post-operative complications included one reoperation (1/11; 9.1%) due to bleeding from one of the laparoscopic trocar sites. Our group concluded that LER can be effectively applied in Perú with good mid-term results and confirmed its effectiveness in accomplishing CBD stone clearance. Based on our results, we recommend the use of LER as a safe and valid therapeutic option for our patients.
La colecistocoledocolitiasis es una enfermedad común a nivel mundial; sin embargo, aún no hay ningún consenso sólido acerca de una sola "terapia ideal" para su manejo. Hoy en día, el método mas utilizado es un procedimiento que involucra "dos estadios", el cual comienza con la extracción endoscópica de cálculos del conducto biliar común (CBD) (colangiopancreatografía retrógrada endoscópica [CPRE]) seguida de una colecistectomía laparoscópica (CL). Sin embargo, este enfoque de "dos estadios" ha mostrado algunas desventajas con el tiempo (necesidad de dos ingresos hospitalarios, necesidad de al menos dos inducciones anestésicas, mayor tasa de pancreatitis post-procedimiento, hospitalizaciones más prolongadas y, por lo tanto, mayores costos). Por otra parte, el rendezvous laparo-endoscópico (RLE), es otra modalidad de tratamiento que implica la resolución en "un solo paso" de la colecistocoledocolitiasis, aplicando un enfoque multidisciplinario hacia el paciente. El RLE es un procedimiento en el cual simultáneamente se realizan la CL y la extracción de cálculos coledocianos por vía endoscópica. El objetivo de este estudio fue presentar nuestros resultados iniciales. Analizamos retrospectivamente once pacientes que fueron intervenidos quirúrgicamente mediante la técnica de RLE en nuestra institución desde mayo de 2017 hasta marzo de 2022. La edad media de los pacientes fue de 50,6 años (rango de edad, 34 - 68) y la mayoría fueron varones 54,.5% (6/11). RLE logró eliminar con éxito los cálculos de CBD en el 90,9 % (10/11) de los casos. En ningún caso se registró pancreatitis post-RLE. Las complicaciones postoperatorias incluyeron una reintervención (1/11; 9,1%) por sangrado de uno de los trócares laparoscópicos. Nuestro grupo concluyó que la técnica RLE se puede aplicar de manera efectiva en Perú con buenos resultados a mediano plazo y confirmó su efectividad para lograr la eliminación de cálculos de CBD. En base a nuestros resultados, recomendamos el uso de RLE como una opción terapéutica segura y válida para nuestros pacientes.
ABSTRACT
SpyGlass DS es un sistema de colangioscopia peroral, asociado a mejor calidad de imagen y conFiguración. Actualmente, existe diversidad en su uso y escasa información sobre su implementación, incluyendo resultados clínicos y eventos adversos. Describir la experiencia de uso del SpyGlass DS en varios centros de referencia en gastroenterología en Colombia, mencionando eficacia y posibles eventos adversos. Este es un estudio observacional (serie de casos). La principal indicación fue coledocolitiasis (n:204), seguida de estenosis biliar (n:40) y pancreatolitiasis (n:16). 49,2% fueron hombres, edad media de 58,6 años, clínicamente con predominio de dolor abdominal (80,5%) e ictericia (86,1%). Todos los casos presentaron diagnóstico por imagen previo (tomografía computarizada, resonancia magnética o ecografía), 98,07% colangiopancreatografía retrógrada endoscópica previa (n:255) y 75% stent plástico biliar. Se utilizó láser en 78/220 pacientes y litotricia electrohidráulica en 142/220 pacientes, con tasas de resolución en una sola sesión 96,15% y 95,07%, respectivamente. Siete casos requirieron segunda sesión de litotricia y 3 pacientes requirieron manejo quirúrgico, uno por pancreatolitiasis con páncreas divisum de base y 2 por hepatolitiasis. 40/260 pacientes presentaron estenosis biliar, 32/40 con hallazgos malignos (colangiocarcinoma) y 8/40 con patología benigna (colangitis esclerosante primaria, cambios inflamatorios inespecíficos) tras estudios histopatológicos. Como complicaciones, se registraron 6 casos de bacteriemia (2,5%), siendo más frecuentes en casos de estenosis. La estancia media postoperatoria fue 2,04 días. Concluimos que el uso del SpyGlass DS es factible en nuestro medio, siendo eficaz para diagnóstico y tratamiento de lesiones biliares, y con bajo riesgo de eventos adversos.
SpyGlass DS is a peroral cholangioscopy system, associated with improved image quality and conFiguration. Currently, there is diversity in its use and little information on its implementation, including clinical outcomes and adverse events. To describe the experience of using SpyGlass DS in several gastroenterology reference centres in Colombia, mentioning efficacy and possible adverse events. This is an observational study (case series). The main indication was choledocholithiasis (n:204), followed by biliary stricture (n:40) and pancreatolithiasis (n:16). 49.2% were male, mean age 58.6 years, clinically with predominance of abdominal pain (80.5%) and jaundice (86.1%). All cases had previous imaging (CT scan, MRI or ultrasound), 98.07% previous endoscopic retrograde cholangiopancreatography (n:255) and 75% biliary plastic stent. Laser was used in 78/220 patients and electrohydraulic lithotripsy in 142/220 patients, with single-session resolution rates of 96.15% and 95.07%, respectively. Seven cases required a second lithotripsy session and 3 patients required surgical management, one for pancreatolithiasis with basal pancreas divisum and 2 for hepatolithiasis. 40/260 patients presented with biliary stricture, 32/40 with malignant findings (cholangiocarcinoma) and 8/40 with benign pathology (primary sclerosing cholangitis, non-specific inflammatory changes) after histopathological studies. As complications, 6 cases of bacteraemia (2.5%) were recorded, being more frequent in cases of stenosis. The mean postoperative stay was 2.04 days. We concluded that the use of SpyGlass DS is feasible in our setting, being effective for diagnosis and treatment of biliary lesions, and with low risk of adverse events.
ABSTRACT
RESUMEN La colangiopancreatografía retrógrada endoscópica (CPRE) es considerado actualmente un procedimiento diagnóstico y terapéutico en lesiones obstructivas del tracto biliar sobretodo coledocolitiasis y estenosis, así como en enfermedades pancreáticas en general. Sin embargo, es conocido el desarrollo de ciertas complicaciones tales como pancreatitis aguda, colangitis aguda, colecistitis entre otras de menor incidencia dentro de las cuales el hematoma subcapsular hepático toma relevancia por su elevada mortalidad. Presentamos el caso de un paciente varón de 52 años que luego de tres horas de ser sometido a CPRE desarrolla dolor abdominal de inicio repentino con reducción importante del hematocrito, y mediante estudio de imágenes se evidencia un hematoma subcapsular hepático. Es manejado inicialmente de forma conservadora y luego se procede a un drenaje percutáneo, evidenciándose posteriormente contenidos residuales en descenso mediante seguimiento radiológico.
ABSTRACT Endoscopic retrograde cholangiopancreatography (ERCP) is currently considered a diagnostic and therapeutic procedure in obstructive lesions of the biliary tract, especially choledocholithiasis and stenosis, as well as in pancreatic diseases in general. However, it is known the development of certain complications such as acute pancreatitis, acute cholangitis, cholecystitis among others of lower incidence within which the hepatic subcapsular hematoma takes relevance due to its high mortality. We present the case of a 52-year-old male patient who three hours after undergoing ERCP develops abdominal pain of sudden onset with significant reduction of hematocrit, and imaging study shows a hepatic subcapsular hematoma. He was initially managed conservatively and then proceeded to a percutaneous drainage, subsequently showing residual descending contents by radiological follow-up.
ABSTRACT
Pancreaticobiliary maljunction (PBM) is a congenital disease with pancreatic and bile ducts joining outside of the duodenal wall. The clinical symptoms of PBM are often characterized by a series of gallbladder and pancreatic disease. PBM has also gradually drawn attention due to recurrent of pancreatitis, bile duct stones and the malignant tumors of biliary system. With the innovative development of endoscopic minimally invasive technology, therapeutic endoscopy may provide new treatment options and ideas for PBM patients, and is expected to achieve the goal of endoscopic minimally invasive intervention to correct structural abnormalities in the pancreaticobiliary duct junction. This paper provided an overview of the definition, endoscopy diagnosis, the pathogenesis and therapeutic endoscopy progress of pancreaticobiliary maljunction.
ABSTRACT
Objective:To explore the safety and efficacy of pancreatic extracorporeal shock wave lithotripsy (P-ESWL) in treating painful chronic pancreatitis patients with pancreatic stones.Methods:The painful chronic pancreatitis patients receiving P-ESWL alone or P-ESWL combined with ERCP at Shanghai Pudong New Area Gongli Hospital from August 2019 to December 2021 were retrospectively analyzed. The success rate of stone fragmentation following P-ESWL, occurrence of postoperative complications, stone clearance rate of the main pancreatic duct and degree of pain relief in the follow-up were evaluated.Results:Among 113 patients, 7 patients were treated with P-ESWL alone and 106 patients were treated by P-ESWL combined with ERCP. The success rate of stone fragmentation was 98.2%. The occurrence of P-ESWL complications was 6.2%. Complete clearance of the main pancreatic duct stones was achieved in 75.2% of patients. With the mean follow-up of 17.5(3-31) months, complete pain relief was achieved in 84.1% of patients. The pain frequency and VAS score of patients treated with P-ESWL alone and P-ESWL combined with ERCP were obviously lower than those before treatment, and the body weight and body mass index were significantly higher than those before treatment, all with statistically significant differences (all P value <0.01). Conclusions:P-ESWL is safe and effective for the management of painful chronic pancreatitis patients with main pancreatic duct stones.
ABSTRACT
Objective:To summarize the experience of treatment for chronic pancreatitis by analyzing the clinical information of 10 533 patients with chronic pancreatitis admitted to First Affiliated Hospital of Naval Medical University (Changhai Hospital) in the past 28 years.Methods:Clinical data including the age, sex, place of birth, admission time, admission age, admission department, discharge time, hospitalization times and treatment methods of chronic pancreatitis patients admitted to Changhai Hospital from January 1995 to February 2022 were analyzed retrospectively. The changes of chronic pancreatitis patients′ admission, demographic characteristics and treatment mode were summarized.Results:A total of 10 533 patients were analyzed, including 7 443 males (70.66%) and 3 090 females (29.34%), and male to female ratio was 2.41∶1. The average age of admission was (45.7±15.0) years. In terms of geographical distribution, East China was the largest, followed by North China and Northwest China. 10 533 patients were admitted for 19 920 times, and there were 18 156 times (91.14%) in gastroenterology department and 1 452 times (7.29%) in general surgery department. Patients in gastroenterology department were admitted for (1.88±1.45) times and the average length of hospitalization was (10.33±5.63) days. A total of 14 134 endoscopic retrograde cholangiopancreatography [(1.45±1.41) times per patient] were performed among 8 022 patients, and 13 882 pancreatic extracorporeal shock wave lithotripsy [(2.22±0.36) times per patient] were performed among 6 629 patients. In general surgery department, patients were admitted for (1.03±0.16) times and the average length of hospitalization was (14.90±9.00) days. 1 242 patients underwent surgical treatment. The ratio of endoscopic therapy to surgery increased from 0.12∶1 in 1995 to 15.72∶1 in 2021.Conclusions:The study shows that chronic pancreatitis was more common in middle-aged males in China, and the treatment modes of chronic pancreatitis in Changhai Hospital had changed from surgery to endoscopic therapy.
