Predictive model of persistent choledocholithiasis in patients with acute biliary pancreatitis.

BACKGROUND: Choledocholithiasis causing acute biliary pancreatitis (ABP) may migrate to the duodenum or persist in the common bile duct (CBD). We developed a model for predicting persistent choledocholithiasis (PC) in patients with ABP. METHODS: This retrospective cohort study included 204 patients, age ≥18 years (mean age: 73 years, 65.7% women), admitted for ABP in 2013-2018, with at least a magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasonography (EUS), and/or endoscopic retrograde cholangiopancreatography (ERCP). Epidemiological, analytical, imaging, and endoscopic variables were compared between patients with and without PC. Multivariate logistic regression analyses were performed to develop a predictive model of PC. RESULTS: Patients underwent MRCP (n=145, 71.1), MRCP and ERCP (n=44, 21.56%), EUS and ERCP (n=1, 0.49%), or ERCP (n=14, 6.86%). PC was detected in 49 patients (24%). PC was strongly associated with CBD dilation, detected in the emergency ultrasound (p<0.001; OR=27; 95% CI: 5.8-185.5), increased blood levels of gamma glutamyl transpeptidase, detected at 72h (p=0.008; OR=3.4; 95% CI: 1.5-8.9); and biliary sludge in the gallbladder (p=0.008; OR=0.03; 95% CI: 0.001-0.3). CONCLUSIONS: The predictive model showed a validated area under the curve (AUC) of 0.858 for detecting PC in patients with ABP. A nomogram was developed based on model results. CONCLUSIONS: The predictive model was highly effective in detecting PC in patients with ABP. Therefore, this model could be useful in clinical practice.

The impact of pregnancy on the outcome of biliary acute pancreatitis. / El impacto del embarazo en el desenlace de pancreatitis biliar aguda.

BACKGROUND AND OBJECTIVE: Acute pancreatitis is one of the most common gastrointestinal conditions requiring hospitalization. Even though its presentation during pregnancy is uncommon, it is a medical challenge. Currently, no studies compare the clinical outcomes between pregnant patients with acute pancreatitis and nonpregnant patients with acute pancreatitis. Our aim was to compare the characteristics and clinical outcomes of pregnant and nonpregnant women with acute pancreatitis. METHODS: We conducted a retrospective study that included all patients admitted to our hospital with acute pancreatitis over a 10-year period. Demographics, general characteristics, and clinical outcomes were evaluated and compared between pregnant and nonpregnant women with acute pancreatitis, at a ratio of 1:5. RESULTS: Over 10 years, 27 pregnant patients with acute pancreatitis were treated. Etiology was biliary in 96% and hypertriglyceridemia was the cause in 3.4% (1 patient). The mean patient age was 26.2 years (range 15-36 years). The main cause of acute pancreatitis was biliary disease (96%). Patients in the study group were in their first, second, or third trimester of pregnancy, at 7.4%, 33.3%, and 59.3%, respectively. In the comparison of pregnant versus nonpregnant patients with acute pancreatitis, there were no differences in age, hospital stay (7.37 vs. 10.8, P=.814), severity (severe 3.7% vs. 16.7%, P=.79), local complications (0% vs. 1.9%, P=.476), or mortality (0% vs. 1.9%, P=.476). CONCLUSIONS: The clinical evolution of both groups with biliary acute pancreatitis was similar, with low morbidity and mortality.

Colangiopancreatografía retrograda endoscópica (CPRE) precoz y pancreatitis aguda biliar (PAB) / Early endoscopic retrograde cholangiopancreatography (ERCP) and acute biliary pancreatitis (ABP)

For over 20 years we have discussed the indication of early endoscopic retrograde cholangiopancreatography (ERCP) (72 h before the onset of symptoms) in acute biliary pancreatitis (ABP), seeking to stop the inflammatory process, reducing complications and mortality, taking into account that ERCP can cause pancreatitis and other complications such as perforation and hemorrhage. To elucidate this problem, there have been multiple meta-analyses based on the same 3 or 5 randomized controlled trials of early ERCP versus conventional treatment (including elective ERCP) in ABP, which have produced conflicting results. There is agreement regarding that it is not indicated in mild ABP, and it is indicated in ABP associated with cholangitis and persistent obstruction of the ampulla of Vater. There is controversy in severe presentation of ABP, since current evidence does not definitely show the usefulness of early ERCP. No more complications related to ERCP have been reported in this situation.

Desde hace más de 20 años se discute la indicación de la colangiopancreatografía retrógrada endoscópica (CPRE) precoz (antes de 72 h del inicio de los síntomas) en la pancreatitis aguda biliar (PAB), buscando detener el proceso inflamatorio, disminuyendo sus complicaciones y su mortalidad, tomando en cuenta que la CPRE puede ser causa de pancreatitis y otras complicaciones como perforación y hemorragia. Para dilucidar este problema se han realizado múltiples meta-análisis basados en los mismos 3 ó 5 estudios aleatorizados y controlados de CPRE precoz versus el tratamiento convencional (que incluye CPRE electiva) en PAB, los cuales han dado resultados discordantes. En lo que hay acuerdo es en que no está indicada en la PAB leve y sí está indicada en la PAB asociada a colangitis y a obstrucción persistente de la ampolla de Vater. En la PAB de presentación grave hay controversia; la evidencia actual no demuestra en forma definitiva la utilidad de una CPRE precoz. No se ha reportado mayor número de complicaciones relacionadas a la CPRE en esta situación.

Rol del endoscopista en la pancreatitis aguda y sus complicaciones / Role of the endoscopist in the management of acute pancreatitis and its complications

For a long time, the aim of the endoscopist in acute pancreatitis has been cleaning up obstructed biliary tract through endoscopic retrograde cholangiopancreatography (ERCP) at the precise momentum, so the main factor causing biliary pancreatitis is treated, decreasing possibilities of complications and modifying the prognosis. However, in the last two decades, the role of the endoscopist has acquired new dimensions so it is possible to treat complications like pseudocysts and walled-of pancreatic necrosis with minimally invasive procedures. This review is focused on technique, indications, follow-up and result of ERCP in acute pancreatitis, drainage of pancreatic pseudocyst and endoscopic necrosectomy.

El rol del endoscopista en la pancreatitis aguda por largo tiempo estuvo abocado fundamentalmente a la posibilidad de desobstruir y limpiar la vía biliar a través de la realización de colangiopancreatografia retrograda endoscópica (CPRE), eliminando así un importante factor ligado el efecto de la coledocolitiasis en la patogénesis, gravedad y complicaciones de la pancreatitis aguda de origen biliar. Sin embargo, en las últimas dos décadas, el papel del endoscopista ha adquirido nuevas dimensiones, ampliándose al tratamiento de ciertas complicaciones de la pancreatitis aguda en general, como son los pseudoquistes pancreáticos y, últimamente, los secuestros de necrosis pancreática. En este artículo se revisan las indicaciones de la CPRE en la pancreatitis aguda, del drenaje de pseudoquiste pancreático y la necrosectomia endoscópica, así como aspectos de la técnica, seguimiento y resultados.

Rol de la colangio pancreatografía retrógrada endoscópica en pacientes con pancreatitis aguda biliar leve y vesícula in situ / Endoscopic retrograde colangiopancreatography (ERCP) among patients with biliary pancreatitis and gallbladder in situ

Background: An early decompression of the biliary tract can be useful in biliary pancreatitis. This can be accomplished with an ERCP. Aim: To analyze prospectively the outcomes of ERCP and eventual endoscopic management among patients with mild acute biliary pancreatitis with gallbladder in situ. Material and methods: We studied 90 consecutive patients aged between 15 and 92 years (71 females) with mild acute pancreatitis and gallbladder in situ, that were subjected to an ERCP and eventual sphincterotomy. Forty nine patients (54 percent) had jaundice and 12 (13 percent) had cholangitis. Results: In 67 patients (74 percent), ERCP detected an abnormal ampulla. The bile duct was successfully cannulated in 89 cases (99 percent). Of these, 42 (47 percent) had a dilated bile duct and 36 (40 percent) had choledocholithiasis. In two patients (2 percent) ERCP was only diagnostic. In the remaining patients, it was therapeutic. Endoscopic treatment was successful in 86 patients (99 percent). No complications arising from the endoscopic procedure were recorded. Follow-up was completed in 84 patients (94 percent). Of these, 10 (12 percent) were not subjected to a cholecystectomy, in eight due to a high surgical risk and in two due to refusal. In the remaining 74 patients, a cholecystectomy was performed during the same hospitalization in 57 (77 percent) and on a deferred basis in 17 (23 percent). Conclusions: In patients with mild acute biliary pancreatitis and gallbladder in situ, ERCP is a safe and effective method.

Objetivo: Analizar en forma prospectiva los resultados de la Colangio Pancreatografía Retrógrada Endoscópica (CPRE) y eventual manejo endoscópico en pacientes portadores de pancreatitis aguda biliar (PAB) leve con vesícula in situ. Material y Método: Se estudiaron 90 pacientes consecutivos con PAB leve y vesícula in situ. La edad promedio fue de 49,5 +/- 18,6 años (78,9 por ciento mujeres y 21,1 por ciento hombres). Del total, 49 pacientes (54,4 por ciento) presentaron ictericia y 12 (13,3 por ciento) colangitis. Resultados: La CPRE pesquisó pato-logia de la ampolla en 67/90 pacientes (74,4 por ciento). La canulación selectiva de la vía biliar resultó exitosa en 89/90 casos (98,9 por ciento). En estos, se demostró una vía biliar dilatada en 42 (47,2 por ciento) y coledocolitiasis en 36 (40,4 por ciento). La CPRE fue diagnóstica en 2 enfermos (2,2 por ciento) y hubo indicación de procedimiento terapéutico en los 87 restantes (97,7 por ciento), este resultó exitoso en 86 (98,9 por ciento). No se presentaron complicaciones derivadas de la cirugía endoscópica. Se completó el seguimiento en 84/89 pacientes (94,4 por ciento). De estos, 10 (11,9 por ciento) no fueron colecistectomizados (8 debido al riesgo quirúrgico y 2 por rechazo a la intervención). De los 74 restantes, 57 (77 por ciento) fueron sometidos a una colecistectomía dentro de la misma hospitalización y 17 (23 por ciento en forma diferida. El 91,9 por ciento de ellas (68/74) mediante laparoscopia. Conclusión: En pacientes con PAB leve y vesícula in situ, la CPRE es un método seguro y efectivo. Además, permite efectuar una colecistectomía por vía laparoscópica, durante la misma hospitalización en la gran mayoría de los pacientes y constituye una alternativa a la colecistectomía en pacientes de alto riesgo quirúrgico.
