We present the case of a 76-year-old male with a history of acute cholecystitis who underwent a scheduled laparoscopic cholecystectomy. Chronic cholecystitis with a thickened cystic duct was observed intraoperatively. The anatomic pathology report found high-grade dysplasia that affected the distal edge of the cystic duct. In view of these findings, an endoscopic retrograde cholangiopancreatography (ERCP) was performed with SpyGlass® and an excrescent lesion suggestive of malignancy adjacent to the cystic-common bile duct junction was observed. A resection of the extrahepatic bile duct was performed with lymphadenectomy of the hepatic hilum and hepaticojejunostomy in a subsequent procedure. The definitive pathology report confirmed pancreaticobiliary intraductal papillary mucinous neoplasia with high-grade dysplasia and free margins.

espanolIntroduccion: la lesion yatrogenica de la via biliar (LYVB) es una complicacion con elevada morbilidad tras la colecistectomia. En los ultimos anos la endoscopia ha adquirido un papel fundamental en el manejo de esta patologia. Metodos: estudio retrospectivo de LYVB tras colecistectomia abierta (CA) o colecistectomia laparoscopica (CL) tratadas en nuestro centro entre 1993 y 2017. Se analizaron los datos referentes a las caracteristicas clinicas, tipo de lesion segun la clasificacion de Strasberg-Bismuth, diagnostico, tecnica de reparacion y seguimiento. Resultados: se estudian 46 pacientes. La incidencia LYVB fue de 0,48%, 0,61% para las CL y 0,24% para las CA. El diagnostico se realizo de forma intraoperatoria en 12 casos (26%) y mediante colangiopancreatografia retrograda endoscopica (CPRE) en 10 (21,7%). Las caracteristicas mas comunes a todos los pacientes con LYVB fueron la colecistitis aguda (20/46, 43,5%), ingreso previo por patologia biliar (16/46, 43,2%) y realizacion de CPRE previa a la colecistectomia (7/46, 18,9%). Los tipos de LYVB mas frecuentes fueron el D (17/46, 36,9%) y el A (15/46, 32,6%). El tratamiento mas empleado fue sutura primaria (13/46, 28,3%) seguido de CPRE (11/46, 23,9%) con esfinterotomia y/o endoprotesis. Ademas, la CPRE se utilizo en el postoperatorio inmediato de 6 pacientes (13%) con reparacion quirurgica de la LYVB para solucionar complicaciones inmediatas. Conclusion: la CPRE es util en el manejo de la LYVB no diagnosticada intraoperatoriamente. Permite localizar la zona lesionada de la via biliar, realizar maniobras terapeuticas y tratar de manera satisfactoria algunas complicaciones postoperatorias. EnglishIntroduction: iatrogenic bile duct injury (IBDI) is a complication with a high morbidity after cholecystectomy. In recent years, endoscopy has acquired a fundamental role in the management of this pathology. Methods: a retrospective study of IBDI after open cholecystectomy (OC) or laparoscopic cholecystectomy (LC) of patients treated in our center between 1993 and 2017 was performed. Clinical characteristics, type of injury according to the Strasberg-Bismuth classification, diagnosis, repair techniques and follow-up were analyzed. Results: 46 patients were studied and IBDI incidence was 0.48%, 0.61% for LC and 0.24% for OC. A diagnosis was made intraoperatively in 12 cases (26%) and by endoscopic retrograde cholangiopancreatography (ERCP) in 10 (21.7%) cases. The most common IBDI patient characteristics were acute cholecystitis (20/46, 43.5%), previous admission due to biliary pathology (16/46, 43.2%) and ERCP prior to cholecystectomy (7/46, 18.9%). The most frequent types of IBDI were D (17/46, 36.9%) and A (15/46, 32.6%). The most commonly used treatment was primary suture (13/46, 28.3%) followed by ERCP (11/46, 23.9%) with sphincterotomy and/or stents. In addition, ERCP was performed during the immediate postoperative period in 6 (13%) patients with a surgical IBDI repair in order to resolve immediate complications. Conclusion: ERCP is useful in the management of IBDI that is not diagnosed intraoperatively. This procedure facilitates the localization of the injured area of the bile duct, therapeutic maneuvers and successful outcomes in postoperative complications.

Aims: to assess oxidative stress in acute pancreatitis, its evolution over time and its relationship with the severity of the disease. Methods: during a two-year period, patients with acute pancreatitis with less than 24 hours of pain were evaluated. Serum was obtained the first, second and fourth day from admittance, if complications were detected, and after recovery. Malondialdehyde was determined by high performance liquid chromatography. Twenty healthy volunteers constituted the control group. Malondialdehyde between groups was compared with Mann-Whitney and Kruskal-Wallis tests; malondialdehyde evolution was studied with Wilcoxon test. Results: one hundred and sixty-nine patients were included (91 women, median age 67 years, range 20-95); 33 suffered a severe episode. Malondialdehyde decreased from first to fourth day (0.600 vs. 0.451 vs. 0.343 μM, respectively, p < 0.05). When complications were detected, malondialdehyde level was similar to that of first and second day (0.473 μM, p > 0.05). In severe attacks malondialdehyde was higher than in control group at day 2 (severe: 0.514; mild: 0.440; control: 0.347 μM, p < 0.05 severe vs. control). Conclusions: an early oxidative stress is observed in acute pancreatitis. In severe attacks, oxidative stress remains high longer than in mild episodes. The onset of complications is associated with high malondialdehyde concentration.

OBJECTIVES To study the prevalence of fecal (FI) and urinary incontinence (UI) in women from Teruel (Spain), as well as the clinical conditions associated with these disorders. METHODS We studied prospectively women with an age range of 20-64 years who were randomly selected from the population seen in a primary care center because of medical disorders not related to incontinence. Patients with functional or cognitive impairment were excluded. Medical and obstetric antecedents, as well as the type and frequency of incontinence symptoms were collected in a questionnaire. RESULTS Out of 115 women, 103 completed the study (mean age: 41+/-12 years range 20-64). UI was present in 34.9% (stress 33%, urge 14%, mixed 47%), FI in 14 (13.6%) (flatus 57%, liquid stools 43%), and 10 (9.7%) displayed both disorders. Age > 42 years and body mass index more or equal of 25 were associated with FI and UI; pregnancy was only associated with UI, but the group of women with more or equal of 2 vaginal deliveries showed a higher frequency of FI (p < 0.05, Chi squared test). In the multivariate analysis, only the presence of UI was associated with FI (OR 6.0; CI 95% 1.7-21). Association of FI and UI was more frequent in women older than 42 years (OR 16.7, CI 95% 1.9-141). No statistical differences were found when smoking, exercise, and type of childbirth were compared between the presence/absence of FI or UI. CONCLUSIONS Urinary and fecal incontinence are frequent in women, and the coexistence of both disorders is not uncommon. Age, overweight and parity are associated with the presence of fecal and/or urinary incontinence.

Objectives: To assess the salivary flow rate, pH, and buffer capacity of healthy volunteers, and their relationships with age, gender, obesity, smoking, and alcohol consumption, and to establish the lower-end value of normal salivary flow (oligosialia). Methods: A prospective study was conducted in 159 healthy volunteers (age > 18 years, absence of medical conditions that could decrease salivary flow). Unstimulated whole saliva was collected during ten minutes, and salivary flow rate (ml/min), pH, and bicarbonate concentration (mmol/l) were measured using a Radiometer ABL 520. The 5 percentile of salivary flow rate and bicarbonate concentration was considered the lower limit of normality. Results: Median salivary flow rate was 0.48 ml/min (range: 0.1-2 ml/min). Age younger than 44 years was associated with higher flow rates (OR 2.10). Compared with women, men presented a higher flow rate (OR 3.19) and buffer capacity (OR 2.81). Bicarbonate concentration correlated with salivary flow rate. The lower-end values of normal flow rate and bicarbonate concentration were 0.15 ml/min and 1.800 mmol/l, respectively. The presence of obesity, smoking, and alcohol consumption did not influence salivary parameters. Conclusions: In healthy volunteers, salivary flow rate depends on age and gender, and correlates with buffer capacity. Obesity, smoking, and alcohol use do not influence salivary secretion.
