Perforaciones duodenales tras colangiopancreatografía retrógrada endoscópica / Duodenal perforations after endoscopic retrograde cholangiopancreatography

INTRODUCCIÓN: La perforación duodenal tras colangiopancreatografía retrógrada endoscópica (CPRE) constituye un cuadro infrecuente. Su manejo es controvertido. El objetivo de este estudio fue analizar los resultados obtenidos en función de su manejo en una serie de 15 pacientes en los que se diagnosticó esta complicación. MÉTODOS: Estudio descriptivo retrospectivo de las perforaciones duodenales tras CPRE, diagnosticadas en un hospital de tercer nivel entre el 2001 y el 2011. Se analizaron las siguientes variables: edad; sexo; motivo de la CPRE; tipo de perforación; momento del diagnóstico; clínica; prueba de imagen; manejo inicial; técnica quirúrgica; estancia global y mortalidad. RESULTADOS: De un total de 1.923 CPRE realizadas se identificaron 15 perforaciones duodenales tras el procedimiento (0,78%). La localización de la perforación fue en la pared duodenal, lejos de la papila (3 casos) y periampulares (12 casos). En 11 pacientes el diagnóstico se sospechó durante el procedimiento. Las perforaciones de pared duodenal se trataron con cirugía urgente. En 7 de las 12 perforaciones periampulares se realizó manejo conservador inicial con evolución favorable en 5 de ellas. En 4 pacientes se realizó cirugía programada posterior. La estancia media hospitalaria fue de 21,2 días (rango: 3-49) y la mortalidad global del 20%. CONCLUSIONES: Las perforaciones tras CPRE constituyen un cuadro de elevada mortalidad, difícil diagnóstico y complicado abordaje terapéutico que precisa ser individualizado. El manejo conservador selectivo constituye una opción válida y segura

INTRODUCTION: Duodenal perforations after endoscopic retrograde cholangiopancreatography (ERCP) are an uncommon complication. The management of this kind of perforation is controversial. The aim of this study was to analyze the results of the management of a series of 15 patients who were diagnosed with this complication. METHODS: Retrospective study of duodenal perforations after ERCP diagnosed at a tertiary level hospital, between 2001 and 2011. The variables age, sex, ERCP indication, type of perforation, time of diagnosis, clinical presentation, radiographic findings, management, surgical technique, length of stay and intrahospital mortality were recorded and analyzed. RESULTS: Out of a total of 1923 ERCP performed, 15 duodenal perforations were detected (0,78%). Perforation site was the duodenal wall (3 cases) and periampullary (12 cases). Eleven perforations were suspected during the procedure. Patients with duodenal wall perforations underwent immediate surgery. Seven of 12 periampullary perforations were managed conservatively with a favorable outcome in 5 of them. Subsequent scheduled surgery was performed in 4 cases. The mean length of hospital stay was 21,2 days (range: 3-49) and intra-hospital mortality was 20%. CONCLUSIONS: Perforations after ERCP have high mortality rates, and require a complicated therapeutic approach that needs to be individualized. Selective conservative management is a valid and safe option in selected patients

Prediction of free bowel perforation in patients with intestinal Behçet's disease using clinical and colonoscopic findings.

BACKGROUND: Gastrointestinal tract involvement in Behçet's disease (BD) often requires surgical intervention due to serious complications such as intestinal perforation, fistula formation, or massive bleeding. AIM: The aims of this study were to investigate the clinical and surgical features of free bowel perforation and to determine the risk factors associated with this complication in intestinal BD patients. METHODS: We reviewed the medical records of 129 patients with intestinal BD treated from September 1988 to September 2008. Among them, 33 patients had intestinal perforations and all underwent emergent or elective laparotomy. RESULTS: The mean age of the patients with bowel perforation was 34.8 ± 15.6 years (range 12-70 years) with a sex ratio of 2.3:1 (male:female). Twenty-seven (81.8%) patients were diagnosed with intestinal BD preoperatively, whereas six (18.2%) patients were diagnosed by pathological examination after operation. Fourteen (42.4%) patients experienced postoperative recurrence of intestinal BD and 11 (33.3%) underwent reoperation. Multivariate Cox hazard regression analysis identified younger age (≤ 25 years) at diagnosis (HR = 3.25; 95% CI, 1.41-7.48, p = 0.006), history of prior laparotomy (HR = 5.53; 95% CI, 2.25-13.56, p = 0.0001), and volcano-shaped intestinal ulcers (HR = 2.84; 95% CI, 1.14-7.08, p = 0.025) as independent risk factors for free bowel perforation in intestinal BD. CONCLUSIONS: According to the results of our study, patients diagnosed with intestinal BD younger than 25 years, who had a history of prior laparotomy or volcano-shaped intestinal ulcers have an increased risk of free bowel perforation.

An exploratory analysis of the epidemiology and surgical management of perforated diverticular disease over a two-year period at a Referral Centre in the Caribbean / Análisis exploratorio de la epidemiología y el tratamiento quirúrgico de la enfermedad diverticular perforada durante un período de dos años en un Centro de Remisión en el Caribe

OBJECTIVE: We present an exploratory analysis of data collected on perforated diverticular disease (PDD) in Barbados and suggest possible areas for further study. SUBJECTS AND METHODS: All cases of perforated diverticular disease treated at the Queen Elizabeth Hospital (QEH) Barbados, between January 1, 2005 and December 31, 2006 were reviewed. The patient's age, gender, location of disease, Hinchey stage, operative procedure, rate of colostomy reversal, length of hospitalization, incidence of peri-operative morbidity and postoperative mortality were analysed using principal components analysis (PCA). RESULTS: Fourteen cases of PDD were treated at the QEH during this period. Six (43%) of the patients had perforated right-sided diverticulitis (PRSD). In the PCA, Dimensions 1 and 2 were the two dimensions examined, as they both had Eigenvalues over 1. Dimension 1 can be taken as an indicator of the intensity of the disease. On dimension 2, length of hospitalization had the highest component loading (0.875). The mean hospital stay was 10.6 days in PRSD, 9.5 in left-sided perforations with primary anastomosis, and 16.2 days for those with a Hartmann's procedure. The overall peri-operative morbidity was 28% and there was no mortality in the series. CONCLUSION: This preliminary study seems to show a relatively high incidence of PRSD in a predominantly Afro-Caribbean population. More research is needed to determine the exact aetiology of this disease. In our experience, primary anastomosis in carefully selected patients with either PRSD or perforated left-sided diverticulitis (PLSD) may result in shorter hospitalization.

OBJETIVO: Presentamos un análisis exploratorio de la enfermedad diverticular perforada (EDP) en Barbados, y sugerimos posibles áreas de análisis ulterior. SUJETOS Y MÉTODOS: Se revisaron todos los casos de enfermedad diverticular perforada tratados en el Hospital Queen Elizabeth (QEH) de Barbados, entre enero 1 de 2005 y diciembre 31 de 2006. Mediante el análisis de componentes principales (ACP), se analizaron los siguientes: edad del paciente, género, localización de la enfermedad, estadio de Hinchey, procedimiento operatorio, tasa de colostomía inversa, tiempo de hospitalización, incidencia de morbilidad perioperatoria, y mortalidad postoperatoria. RESULTADOS: Catorce casos de EDP fueron tratados en el HQE durante este período. Seis (43%) de los pacientes presentaban diverticulitis del lado derecho perforada (DLDP). En el ACP, las dimensiones 1 y 2 fueron las dos dimensiones examinadas, ya que ambas tenían valores propios por encima de 1. La dimensión 1 puede tomarse como indicador de la intensidad de la enfermedad. En la dimensión 2, el tiempo de hospitalización tuvo la carga de componente más alta (0.875). La estadía promedio en el hospital fue de 10.6 días en los casos de DLDP, 9.5 en las perforaciones del lado izquierdo con anastomosis primaria, y 16.2 días para aquellos con procedimiento de Hartmann. La morbilidad perioperatoria fue 28% y no hubo mortalidad en la serie. CONCLUSIÓN: Este estudio preliminar parece mostrar una incidencia relativamente alta de DLDP en una población predominantemente afro-caribeña. Se necesita más investigación a fin de determinar la etiología exacta de esta enfermedad. En nuestra experiencia, la anastomosis primaria en pacientes cuidadosamente seleccionados, que sufren de DLDP o padecen diverticulitis del lado izquierdo perforada (DLIP), puede tener por resultado una hospitalización más corta.

Racial disparities in the management of pediatric appenciditis.

BACKGROUND: Our objective was to compare the racial differences in incidence and management of pediatric appendicitis. MATERIALS AND METHODS: Data for this study come from two large national hospital discharge databases from the Agency for Healthcare Research and Quality Healthcare Costs and Utilization Project: The Nationwide Inpatient Sample (NIS) and the Kids' Inpatient Database (KID). Analysis was restricted to age less than 18 years with an ICD-9 diagnosis of either simple (540.9) or complex (540.0 and 540.1) appendicitis. Data were weighted to represent national estimates. Incidence was defined as the number of new disease cases divided by the number of at risk hospitalized children. RESULTS: The data for this study contained an estimated 428,463 [95% confidence interval (CI) = 414, 672-442, 253] cases of appendicitis, representing approximately 65,000 to 75,000 cases annually. Multi-variant analysis suggests that African-Americans, as compared to Caucasians, were less prone to develop appendicitis [odds ratio (OR) = 0.39, 95% CI (0.38, 0.41)], but less frequently underwent laparoscopic treatment [OR = 0.78, 95% CI (0.74, 0.87)], and were more likely to have complex appendicitis [OR = 1.39, 95% CI (1.30, 1.49)]. In contrast, Hispanics were more likely than Caucasians to both develop appendicitis [OR = 1.48, 95% CI (1.41, 1.56)] and to have complex disease [OR = 1.10, 95% CI (1.05, 1.16)]. The incidence of appendicitis was less frequent in females versus males [OR = 0.69, 95% CI (0.68, 0.70)] but the likelihood of laparoscopic exploration was higher [OR = 1.39, 95% CI (1.34, 1.43)]. Finally, children with public insurance [OR = 1.25, 95% CI (1.21, 1.29)] and uninsured children [OR = 1.10, 95% CI (1.04, 1.16)] were more likely to have complex appendicitis when compared to children with private insurance. CONCLUSIONS: African-American children with appendicitis have lower overall hospitalization rates, higher rates of perforation, a greater delay to surgical management, and lower laparoscopic rates. In contrast, Hispanic children more frequently had appendicitis and complex disease. The treatment of African-American and Hispanic children overall was associated with a longer hospital stay and higher charges. The lower incidence of appendicitis in African-American children is incompletely understood and the disparity in surgical management among minority children remains troubling.

Audit of acute appendicitis in a black South African population.

This is a prospective study of 212 black South African patients operated on with a pre-operative diagnosis of acute appendicitis. There were 143 male and 69 female patients. Forty-four patients had normal appendices and 122 non-perforated and 46 perforated acute appendices. The appendix was normal in 12 male and 32 female patients. Most presenting signs had a high positive predictive value but few had a high negative predictive value. There was no significant difference in the systemic response between perforated and non-perforated groups. Delay in presentation accounted for the majority of perforated appendices, while there was no causal relationship between in-hospital observation and perforation. The complication rate was higher and hospital stay longer in the perforated group. We concluded that the presentation and clinical course of acute appendicitis in the population of black South Africans catered to by our hospital is not very different from that in the white population elsewhere in the world.
