Clinical characteristics of patients with colon complications after necrotizing pancreatitis: a retrospective cohort study / 中华外科杂志

Objective: To investigate the clinical characteristics of colon complications in patients with necrotizing pancreatitis(NP). Methods: The clinical data of 403 patients with NP admitted to the Department of General Surgery,Xuanwu Hospital, Capital Medical University from January 2014 to December 2021 were retrospectively analyzed. There were 273 males and 130 females,aged (49.4±15.4) years(range: 18 to 90 years). Among them,there were 199 cases of biliary pancreatitis,110 cases of hyperlipidemic pancreatitis,and 94 cases of pancreatitis caused by other causes. A multidisciplinary diagnosis and treatment model was used to diagnose and treat patients. Depending on whether the patients had colon complications,they were divided into colon complications group and noncolon complications group. Patients with colon complications were treated with anti-infection therapy,parental nutritional support,keeping the drainage tube unobstructed,and terminal ileostomy. The clinical results of the two groups were compared and analyzed using a 1∶1 propensity score match(PSM) method. The t test,χ2 test, or rank-sum test was used to analyze data between groups,respectively. Results: The incidence of colon complications was 13.2%(53/403),including 15 cases of colon obstruction,23 cases of colon fistula,and 21 cases of colon hemorrhage. After PSM,the baseline and clinical characteristics at admission of the two groups of patients were comparable (all P>0.05). In terms of clinical outcome,compared to patients with NP without colon complications,the number of patients with colon complications who received minimally invasive intervention(88.7%(47/53) vs. 69.8%(37/53),χ2=5.736,P=0.030),the number of minimally invasive interventions (M(IQR))(2(2) vs. 1(1), Z=4.638,P=0.034),the number of patients with multiple organ failure(45.3%(24/53) vs. 32.1%(17/53),χ2=4.826,P=0.041),and the number of extrapancreatic infections(79.2%(42/53) vs. 60.4%(32/53),χ2=4.476,P=0.034) increased significantly. The time required for enteral nutrition support(8(30)days vs. 2(10) days, Z=-3.048, P=0.002), parental nutritional support(32(37)days vs. 17(19)days, Z=-2.592, P=0.009),the length of stay in the ICU(24(51)days vs. 18(31)days, Z=-2.268, P=0.002),and the total length of stay (43(52)days vs. 30(40)days, Z=-2.589, P=0.013) were also significantly prolonged. However,mortality rates in the two groups were similar(37.7%(20/53) vs. 34.0%(18/53),χ2=0.164,P=0.840). Conclusions: Colonic complications in NP patients are not rare,which can lead to prolonged hospitalization and increased surgical intervention. Active surgical intervention can help improve the prognosis of these patients.

Introduction: Open pancreatic necrosectomy is a surgical technique used in necrosis infection. Objective: To identify the factors related to prognosis in patients operated on under the diagnosis of acute necrotizing pancreatitis. Methods: A prospective cohort study was carried out in patients operated on under the diagnosis of acute necrotizing pancreatitis, in the intensive care unit of Carlos Manuel de Céspedes General University Hospital of Bayamo, Granma, Cuba, in the period 2018-2020. Sixty-one patients with this diagnosis were included. Demographic, clinical, humoral and surgical variables were studied. A bivariate and multivariate strategy was used. Results: In the bivariate analysis, the influence of age (relative risk [RR]=3.34; 95 percent confidence interval [CI]: 0.17-0.68) and tomographic severity index (RR=1.85; 95 percent CI: 0.66-2.37), as well as multiple organ dysfunction (RR=5.06; 95 percent CI: 1.08-2.15), early surgery (RR=2.78; 95 percent CI: 1.00-3.34) and necrosis infection (RR=6.60; 95 percent CI: 1.01-5.23) were highlighted. In the multivariate logistic regression model, multiple organ dysfunction (RR=6.58; 95 percent CI: 2.40-18.08) and infection of necrosis (RR=14.20; 95 percent CI: 5.93-34.01) were included as independent variables associated with prognosis. Conclusions: Mortality analysis evidenced that the factors that showed significant association were multiple organ dysfunction and necrosis infection(AU)

Laparoscopic transgastric necrosectomy in treatment of wall-off pancreatic necrosis / 中华外科杂志

Mini-invasive surgical or endoscopic step-up approach is the first choice of pancreatic necrosectomy for infected wall-off necrosis. Surgical debridement has the advantage of high efficiency,low cost and good accessibility,while the complication rate of pancreatic fistula and incision hernia after endoscopic necrosectomy is low.Laparoscopic transgastric necrosectomy(LTGN) can combine the advantages of surgical and endoscopic debridement,and may become one of the important methods for the surgical treatment of necrotizing pancreatitis in the future. This paper focuses on the technical advantages,surgical points,indications and application status of LTGN,so as to provide reference for the technical promotion.

Pancreatitis aguda necrotizante infectada. Desbridamiento retroperitoneal video asistido / Infected necrotizing pancreatitis. Video-assisted retroperitoneal debridement

Resumen El tratamiento escalonado de la pancreatitis aguda necrotizante infectada consiste en el uso de antibióticos de amplio espectro, drenaje y necrosectomía mínimamente invasiva, si fuese necesaria. Esto ha reemplazado a la cirugía abierta como el estándar de tratamiento. El desbridamiento retroperitoneal video asistido (VARD), es una forma de necrosectomía quirúrgica mínimamente invasiva. Presentamos una serie de 5 casos (2 mujeres y 3 varones) con pancreatitis aguda grave y necrosis pancreática infectada tratados de forma escalonada y VARD. El rango de edad fue de 27 a 60 años. Todos los pacientes tuvieron pancreatitis de etiología biliar. El rango del APACHE II fue de 16 a 20. El rango del tiempo para el drenaje percutáneo lumbar fue de 4 a 7 semanas. Hubo una complicación del drenaje percutáneo (fistula duodenal) que se resolvió con tratamiento médico. Los cultivos de todas las necrosis fueron positivos. El tiempo para la realización del VARD tuvo un rango de 6 a 10 semanas. Un paciente requirió dos procedimientos. Hubo dos fístulas pancreáticas tipo B asociadas al VARD, que se trataron conservadoramente. No hubo mortalidad. A largo plazo, dos pacientes fueron diagnosticados de insuficiencia pancreática exocrina y endocrina. Concluimos que en los pacientes con necrosis pancreática infectada que requieran desbridamiento, el VARD es una alternativa segura, efectiva y con buenos resultados a largo plazo.

Abstract The step-up approach for infected necrotizing pancreatitis, consisting of broad-spectrum antibiotics, drainage followed, if necessary, by minimally invasive necrosectomy, has replaced open surgery as the standard of management. Video-assisted retroperitoneal debridement (VARD) is a surgical minimally invasive necrosectomy. This is a 5 cases series (2 female and 3 males) with severe acute pancreatitis and infected pancreatic necrosis who underwent step up approach and VARD. The age ranged from 27 to 60 years old. Al patients had biliary pancreatitis. APACHE II ranged from 16 to 20. The time to percutaneous lumbar drainage ranged from 4 to 7 weeks. There was one complication associated with percutaneous drainage (duodenal fistula) with nonoperative management. All necrotizing pancreatitis had positive cultures. The time to perform VARD ranged from 6 to 10 weeks. One patient required two procedures. There were two type B pancreatic fistulas associated with VARD, managed nonoperatively. There was no mortality. During long-term follow-up two patients were diagnosed with exocrine and endocrine pancreatic insufficiency. We conclude that VARD is a safe and effective procedure in patients with infected necrotizing pancreatitis requiring debridement, and with good long-term outcomes.

Necrotizing pancreatitis: description of videoscopic assisted retroperitoneal debridement (vard) technique with covered metallic stent / Pancreatite necrosante: descrição da técnica de debridamento videoendoscópico retroperitoneal (vard) assistida com stent metálico recoberto

ABSTRACT Background : Acute pancreatitis is the third most common gastrointestinal disorder requiring hospitalization in the United States, with annual costs exceeding $2 billions. Severe necrotizing pancreatitis is a life-threatening complication developed in approximately 20% of patients. Its mortality rate range from 15% in patients with sterile necrosis to up 30% in case of infected one associated with multi-organ failure. Less invasive treatment techniques are increasingly being used. These techniques can be performed in a so-called step-up approach. Aim: To present the technique for videoscopic assisted retroperitoneal debridement (Vard technique) with covered metallic stent in necrotizing pancreatitis. Method: A guide wire was inserted through the previous catheter that was removed in the next step. Afterwards, the tract was dilated over the guide wire. Then, a partially covered metallic stent was deployed. A 30 degrees laparoscopic camera was inserted and the necrosis removed with forceps through the expanded stent under direct vision. Finally, the stent was removed and a new catheter left in place. Result : This technique was used in a 31-year-old man with acute pain in the upper abdomen and diagnosed as acute biliary pancreatitis with infected necrosis. He was treated with percutaneous drains at weeks 3, 6 and 8. Due to partial recovery, a left lateral VARD was performed (incomplete by fixed and adherent tissue) at 8th week. As the patient´s inflammatory response was reactivated, a second VARD attempt was performed in three weeks later. Afterwards, patient showed complete clinical and imaging resolution. Conclusions : Videoassisted retroperitoneal necrosectomy using partially covered metallic stent is a feasible technique for necrotizing pancreatitis.

RESUMO Racional: A pancreatite aguda é a terceira doença gastrointestinal mais comum que requer hospitalização nos Estados Unidos, com custos anuais superiores a $ 2 bilhões. A pancreatite necrosante grave é uma complicação potencialmente fatal, desenvolvida em aproximadamente 20% dos pacientes. A taxa de mortalidade varia de 15% em pacientes com necrose estéril para 30% no caso de uma infecção infectada com falência multiorgânica. As técnicas de tratamento menos invasivas são cada vez mais utilizadas. Elas podem ser realizadas em uma abordagem chamada "step-up". Objetivo: Apresentar a técnica de desbridamento retroperitoneal assistido com videografia (técnica VARD) com stent metálico coberto em pancreatite necrosante. Método: Um fio guia é inserido através do cateter anterior que foi removido no próximo passo. Depois, o trajeto é dilatado sobre o fio guia. Em seguida, um stent metálico parcialmente coberto é implantado. Uma câmera laparoscópica de 30º é inserida e a necrose removida com fórceps através do stent expandido sob visão direta. Finalmente, o stent é removido e um novo cateter deixado no lugar. Resultado: Esta técnica foi utilizada em um homem de 31 anos com dor aguda na parte superior do abdome e diagnosticado como pancreatite biliar aguda com necrose infectada. Ele foi tratado com drenos percutâneos nas semanas 3, 6 e 8. Devido à recuperação parcial, realizou-se um VARD lateral esquerdo (incompleto por tecido fixo e aderente) na 8ª semana. À medida que a resposta inflamatória do paciente foi reativada, uma segunda tentativa VARD foi realizada em três semanas mais tarde. Posteriormente, o paciente apresentou resolução clínica e de imagem completa. Conclusão: A necrosectomia retroperitoneal assistida em vídeo com stent metálico parcialmente coberto é uma técnica viável para pancreatite necrosante.

Minimally invasive endoscopic treatment of necrotizing pancreatitis: A case report with images and review of the literature / Tratamento endoscópico minimamente invasivo: relato de caso e revisão da literatura

Summary Necrotizing pancreatitis with fluid collections can occur as a complication of acute pancreatitis. The management of these patients depends on the severity and involves multiple medical treatment modalities, as clinical intensive care and surgical intervention. In this article, we show a severe case of walled-off pancreatic necrosis that was conducted by endoscopic drainage with great clinical outcome.

Resumo Pancreatite necrosante com coleções pode ocorrer como complicação da pancreatite aguda. O manejo desses pacientes depende da gravidade e envolve múltiplas modalidades médicas de tratamento, como terapia clínica intensiva e intervenção cirúrgica. Neste artigo, mostramos um caso grave de necrose pancreática com ótima resolução clínica após drenagem endoscópica.

Aspectos cirúrgicos da pancreatite aguda necrosante / Surgical implications of acute necrotizing pancreatitis

Objetivos: Sumarizar as recomendações da literatura atual quanto ao manejo da pancreatite aguda necrosante. Métodos: Foram selecionados artigos publicados nos últimos anos nas bibliotecas Cochrane e PubMed, pesquisados nos meses de maio e junho de 2017. Resultados: O diagnóstico de pancreatite aguda (PA) é estabelecido com a presença de pelo menos 2 dos 3 critérios a seguir: dor compatível com PA; elevação de amilase e lipase séricas 3 vezes ou mais do limite superior da normalidade; e alteração compatível com PA em Tomografia Computadorizada (TC) ou Ressonância Nuclear Magnética (RNM). O tratamento cirúrgico da PA está indicado na necrose pancreática infectada e na necrose estéril com sintomas (febre crônica, letargia, inapetência alimentar, náusea). Ele deve ser feito de imediato nos pacientes hemodinamicamente instáveis, enquanto que nos pacientes estáveis recomenda-se estabilizar o processo inflamatório por no mínimo 4 semanas antes do procedimento. Atualmente recomenda-se que se inicie a intervenção com técnicas minimamente invasivas, como drenagem endoscópica e drenagem percutânea, pois se sugere que tais técnicas resultam em menos efeitos adversos e morbidade. Na impossibilidade do uso dessas técnicas, podem ser realizadas cirurgia aberta ou por videolaparoscopia, devendo a indicação ser individualizada e dependente da experiência do cirurgião. Nos casos de pancreatite aguda biliar, a colecistectomia semieletiva é mandatória, pois o risco de recorrência de pancreatite é muito alto caso não seja feito o procedimento. Conclusões: Novos estudos são necessários para que seja possível definir com precisão o melhor tempo cirúrgico e a melhor técnica de necrosectomia/desbridamento no manejo da pancreatite aguda cirúrgica.

Aims: Summarize the current recommendations in the set of necrotizing pancreatitis management. Methods: Publications on pancreatitis management published in the last years were reviewed and selected from May to June 2017 in Cochrane e PubMed database. Results: The diagnosis of acute pancreatitis (AP) is established with the presence of at least 2 of the following 3 criteria: AP compatible pain; Elevation of serum amylase and lipase 3 times or more of the upper limit of normal; And alteration compatible with AP in CT or Magnetic Nuclear Imaging (MRI). Surgical treatment of AP is indicated in infected pancreatic necrosis and in sterile necrosis with symptoms (chronic fever, lethargy, ingestion of food, nausea). It should be done immediately in hemodynamically unstable patients, whereas in stable patients it is recommended to stabilize the inflammatory process for at least 4 weeks before the procedure. It is now recommended that intervention be initiated with minimally invasive techniques, such as endoscopic drainage and percutaneous drainage, as it is suggested that such techniques result in fewer adverse effects and morbidity. In the impossibility of using these techniques, open surgery or laparoscopy may be performed, and the indication must be individualized and dependent on the experience of the surgeon. In cases of acute biliary pancreatitis, semi-elective cholecystectomy is mandatory because the risk of recurrence of pancreatitis is very high if the procedure is not performed. Conclusions: Further studies are needed to determine the best moment to intervene and the best necrosectomy technique with regard to surgical PA management.

Therapeutic alternatives for the treatment of infected pancreatic necrosis: an overview / Alternativas terapéuticas para el tratamiento de la necrosis pancreática infecciosa: una visión general

Despite diagnostic and therapeutic advances, the treatment of infected pancreatic necrosis (IPN) continues to be a complex problem to solve. The aim of this study is to evaluate the effectiveness of different surgical alternatives for the treatment of IPN. Articles published between 2000 to 2013, and related to effectiveness of open surgery (OS) and minimally invasive treatmente (MIT) in patients with IPN were evaluated. PubMed, MEDLINE, The Cochrane Database of Systematic Reviews, Cochrane Central Register RCT, DARE, IBECS, SciELO, LILACS, PAHO, WHOLIS, ASERNIP-S, NIHR, HTA, Clinical Excellence, York Health Economic Consortium and Tripdatabase were reviewed, searching systematic reviews (SR), randomized clinical trials (RCT) and observational studies (OST), in which the effectiveness of OS and MIT was evaluated in relation to the variables mortality, intra-abdominal bleeding, development of enterocutaneous fistula or hollow viscera perforation, development of pancreatic fistula, reoperations for complications, reoperations for new necrosectomy, development of diabetes mellitus and pancreatic enzyme requirements. Three hundred eighty-nine articles were retrieved, 10 of which met the selection criteria (2 SR, 1 RCT and 7 OST). The studies have a level of evidence of 2a, 2b, 3a and 4. MIT are associated with better results than OS in all variables analyzed, but significantly only in the development of diabetes mellitus and pancreatic enzyme requirement. Articles found are few and heterogeneous, making meaningful conclusions difficult. Studies with a better level of evidence, methodological quality and population size are needed to make conclusions and recommendations.

A pesar de los avances diagnósticos y terapéuticos, el tratamiento de la necrosis pancreática infecciosa (NPI) sigue siendo un problema complejo de resolver. El objetivo de este estudio es evaluar la eficacia de las diferentes alternativas quirúrgicas para el tratamiento del NPI. Fueron evaluados artículos publicados entre 2000 y 2013, relacionados con la efectividad de la cirugía abierta (CA) y el tratamiento mínimamente invasivo (TMI) en pacientes diagnosticados con NPI. Se PubMed, MEDLINE, The Cochrane Database of Systematic Reviews, Cochrane Central Register RCT, DARE, IBECS, SciELO, LILACS, PAHO, WHOLIS, ASERNIP-S, NIHR, HTA, Clinical Excellence, York Health Economic Consortium y Tripdatabase, en búsqueda de revisiones sistemáticas (RS), ensayos clínicos aleatorios (ECA) y estudios observacionales (EO). En estos estudios se evaluó la eficacia de la cirugía y el TMI en relación con diferentes variables, como la mortalidad, el sangrado intra-abdominal, el desarrollo de fístula enterocutánea o la perforación de víscera hueca, el desarrollo de fístula pancreática, reintervenciones por complicaciones, reintervenciones por necrosectomía, el desarrollo de diabetes mellitus y la necesidad de enzimas pancreáticas. Se consiguieron 389 artículos, de los cuales 10 cumplieron con los criterios de selección (2 RS, 1 ECA y 7 EO). Los estudios presentaron un nivel de evidencia de 2a, 2b, 3a y 4. El TMI se asocia con mejores resultados que la CA en todas las variables analizadas, pero en forma significativa sólo en el desarrollo de la diabetes mellitus y la necesidad de enzimas pancreáticas. Los artículos encontrados son pocos y heterogéneos, lo que hace difícil poder alcanzar conclusiones significativas. Se necesitan estudios con un mejor nivel de evidencia, calidad metodológica y tamaño de población estudiada para poder establecer conclusiones y recomendaciones.

Necrosectomía laparoscópica en pancreatitis aguda / Laparoscopic necrosectomy in acute pancreatitis

Introducción: la pancreatitis aguda, a pesar de los avances recientes, es aún un problema para la cirugía actual. Su forma necrotizante constituye la forma más temida con una mortalidad estimada del 50 por ciento de los casos operados, y hasta el 100 por ciento de los no operados. Un número significativo de afectados de pancreatitis necrotizante requerirá cirugía, siendo la necrosectomía por laparotomía la forma fundamental del manejo, sin embargo, nuevas modalidades de cirugía mínimamente invasivas han sido incorporadas al tratamiento. El abordaje laparoscópico constituye una de estas modalidades con las consiguientes ventajas que supone el método en la ulterior evolución del paciente y su rápida recuperación, siendo también una de las rutas menos empleadas y evaluadas fundamentalmente por los requerimientos técnicos, personal entrenado y condiciones del paciente que se necesitan. Caso clínico: se trató de un paciente con diagnóstico clínico y tomográfico de pancreatitis aguda necrotizante, intervenido quirúrgicamente a las tres semanas de su ingreso por la presencia de un absceso pancreático y ulteriormente por necrosis extensa infectada. Se logra una evolución satisfactoria siendo egresado sin complicaciones. Conclusiones: el abordaje laparoscópico de estos pacientes es posible siempre que existan las condiciones técnicas disponibles, el personal entrenado, y las condiciones del paciente lo permitan. Esto significaría muchas ventajas para los mismos, con resultados superiores a la vía convencional incluyendo la posibilidad de una marcada reducción de la alta tasa de morbilidad y mortalidad aún presentes en la cirugía de la pancreatitis aguda complicada(AU)

Introduction: despite recent advances, acute prancreatitis is still a problem in current surgery. Its necrotizing form is the most feared form with estimated mortality rate of 50 percent of surgical cases and up to 100 percent of non-operated cases. A significant number of patients with necrotizing pancreatitis will require surgery, being laparoscopic necrosectomy the fundamental management procedure. However, new minimally invasive surgical modalities have been introduced in this treatment. The laparoscopic approach is one of these modalities with further advantages in the future progression of the patient and his rapid recovery; this is one of the least used and evaluated routes, mainly due to technical requirements, trained staff and conditions of the patient to perform the procedure. Clinical case: a patient with clinical and tomographic diagnosis of acute necrotizing pancreatitis was surgically treated after three weeks of admission, since this patient presented pancreatic abscess first and infected extensive necrosis later. The recovery was satisfactory without complications. Conclusions: the laparoscopic approach of these patients is possible, provided that there are available technical conditions, trained staff and the required conditions of the patient. This will bring about many advantages, with higher results than in the conventional route, including the possibility of marked reduction of the high mortality rate still present in complicated acute pancreatitis surgery(AU)

Alternativas de manejo de colecciones en pancreatitis aguda / Alternatives in the treatment of collections in acute pancreatitis

Acute pancreatitis is a disease that presents heterogeneously with varying severity depending on pancreatic parenchyma and peripancreatic fat. The aim of this publication is to present the nomenclature in use in the different collections that develop in the evolution of acute pancreatitis, and management options of these collections, focusing on the management of infected pancreatic necrosis; emphasizing the benefits, results and limitations of each technique and describing some techniques under development.

La pancreatitis aguda es una enfermedad que se presenta en forma heterogénea con distinta gravedad según el compromiso del parénquima pancreático y de la grasa peripancreática. El objetivo de esta publicación es dar a conocer la nomenclatura en uso en las distintas colecciones que se manifiestan en la evolución de la pancreatitis aguda y las opciones de manejo de estas colecciones, enfocándose en el manejo de la necrosis pancreática infectada; enfatizando las ventajas, resultados y limitaciones de cada técnica, además de describir algunas técnicas en desarrollo.

Evaluación y validación de las indicaciones quirúrgicas en la pancreatitis aguda con necrosis, en el Hospital Nacional Edgardo Rebagliati Martins / Evaluation and validation of surgical indications in acute pancreatitis with necrosis, at the National Hospital Edgardo Rebagliati Martins

OBJETIVO: El objetivo de este estudio es evaluar la eficacia de las indicaciones quirúrgicas en la pancreatitis aguda. MATERIALES Y MÉTODOS: Durante el periodo comprendido entre Mayo del 2000 a Junio del 2009 se realizo un estudio de manera prospectiva donde se incluyo a 107 pacientes con Pancreatitis aguda grave con necrosis que fueron operados en la Unidad de Pancreatitis del Hospital Rebagliati. Se dividió a los pacientes de acuerdo a la indicación quirúrgica recibida. Indicación A: Aquellos pacientes que fueron operados por presentar punción por aguja fina positiva (PAF) Indicación B: Pacientes operados por presentar sepsis en ausencia de foco infeccioso extra pancreático. RESULTADOS: Cuando evaluamos la efectividad de cada indicación quirúrgica para detectar infección de la necrosis pancreática pudimos observar que cuando se opero al paciente utilizando la indicación quirúrgica A el 89% presentaban necrosis pancreática infectada, mientras que cuando se utilizo la indicación B solo se encontró infección de la necrosis pancreática en el 51% de los casos (p=0.001). Por lo tanto cuando se utilizo la primera indicación solo el 11% de los operados presento una necrosis estéril mientras que cuando usamos la indicación B operamos por ôerrorõ de esta a un 48% de pacientes que no tenían una indicación quirúrgica por no presentar una necrosis infectada. CONCLUSIONES: La punción por aguja fina es la indicación quirúrgica por excelencia en la pancreatitis aguda grave con necrosis descartando a la indicación de ôSepsisõ en ausencia de foco infeccioso extra pancreático que no responde al tratamiento en UCI por más de 72 horas (indicación B), ya que no es una adecuada indicación porque nos induce a operar pacientes que no tienen una real indicación quirúrgica (necrosis estéril) debido a que estos pacientes pueden ser manejados médicamente.

OBJECTIVE: The purpose of this study is to evaluate efficacy of the surgical indications in acute pancreatitis MATERIAL AND METHODS: During the period from May 2000 to June 2009, 107 operated patients with pancreatic necrosis were treated in the Severe Acute Pancreatitis Unit of the HNERM a comparison was made by separating the patients in two groups according to the surgical indication. An analysis was carried out in order to evaluate which type of surgical indication has the best results according to age, severity of the case, return to oral intake, hospital stay, complications and mortality. RESULTS: On evaluating the indication by positive puncture for detecting necrosis infection we found that 89% of the patients operated due to this indication showed infected necrosis while those operated due to the indication of sepsis without response to the ICU treatment only reached 51%. Surgical complications and re operations, was higher among the patients whose indication was sepsis without response to the ICU treatment (Indication B) in comparison with positive FNA. (Indication A) CONCLUSION: Positive fine needle aspiration is the surgical indication par excellence in acute pancreatitis with necrosis. We consider that the indication of sepsis that do not respond for more than 72 hours to treatment in the ICU regardless that negative FNA should not be taken into account, due to the very high percentage of sterile necrosis found at the time of surgery.

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.

Necrosectomía laparoscópica en pancreatitis aguda / Laparoscopic necrosectomy in severe pancreatitis: retrospective analysis of 11 patients

Background: Laparoscopic surgery can be used in the treatment of severe acute pancreatitis. Aim: To report the experience with laparoscopic necrosectomy and abscess drainage in severe acute pancreatitis. Material and Methods: Retrospective analysis of medical records of 11 patients aged 13 to 78 years (10 males), with severe pancreatitis, subjected to laparoscopic necrosectomy or abscess drainage between 2006 and 2009. Results: Operative time ranged from 110 to 205 min. In all cases, a satisfactory necrosectomy and collection drainage were performed. No complications were recorded and no patient required to be converted to open surgery. Five patients were reoperated. In three of these, the laparoscopic approach was used again. Conclusions: Laparoscopic necrosectomy is safe and useful for patients with severe pancreatitis.

Introducción: La pancreatitis aguda grave, asociada a necrosis pancreática infectada, tiene una elevada mortalidad. En la mayoría de los casos, el tratamiento es quirúrgico, sin embargo, este se asocia a una alta morbilidad. El desarrollo de la cirugía mínimamente invasiva ha permitido incorporar la técnica laparoscópica al tratamiento de esta enfermedad. Objetivo: Presentar nuestra experiencia en necrosectomía y drenaje de abscesos por vía laparoscópica en pacientes con pancreatitis aguda grave. Pacientes y Métodos: Análisis retrospectivo de todos los pacientes con diagnóstico de pancreatitis aguda grave con necrosis infectada y/o abscesos sometidos a necrosectomía y drenaje de abscesos por vía laparoscópica. Se describen los datos demográficos, etiología de la pancreatitis aguda, imágenes pre y post-operatorias, así como los detalles de cada cirugía, la indicación quirúrgica, complicaciones, necesidad de re-operaciones y evolución tardía. Resultados: La serie está compuesta por 11 pacientes, todos con diagnóstico de pancreatitis aguda grave, operados entre abril de 2006 y junio de 2009. El tiempo operatorio promedio fue 138 min (110-205 min). En todos los casos, se realizó una necrosectomía satisfactoria y drenaje de colecciones. No hubo complicaciones derivadas de la técnica laparoscópica ni conversión a cirugía abierta en ningún paciente durante la primera cirugía. Cinco pacientes fueron re-operados, 3 de ellos por vía laparoscópica. Conclusiones: La necrosectomía laparoscópica es una alternativa válida y disponible en nuestro centro, con resultados comparables y probablemente superiores a la cirugía abierta, y con resultados satisfactorios en cuanto a morbilidad, protección de la pared abdominal y mortalidad postoperatoria.

Pancreatitis aguda necrótica en la unidad de cuidados intensivos: Una comparación entre el tratamiento médico conservador y quirúrgico / Necrotic acute pancreatitis in the intensive care unit: A comparison between conservative and surgical medical treatment

OBJETIVO: Determinar el pronostico del tratamiento medico y quirúrgico de pacientes con pancreatitis aguda necrótica. INTRODUCCION: El tratamiento de pancreatitis aguda severa es multidisciplinario y requiere la evaluación de los pacientes día a día, esto permite observar los cambios y dar terapia oportuna. El tratamiento incluye: admisión en UCI, fluidos, nutrición y antibióticos, así como otros soportes de vida para paciente critico. Con esto, los pacientes pueden ser tratados conservadoramente o si fuese necesario, con intervención quirúrgica. METODOS: Un estudio retrospectivo de pacientes con pancreatitis aguda necrótica, que ingresaron a la Unidad de Cuidados Intensivos, entre enero del 2004 a agosto del 2006. Los pacientes con pancreatitis aguda necrótica sin signos de sepsis fueron sometidos a tratamiento medico conservador. Se realizó una punción aspiración con aguja fina, a partir de la cuarta semana, a los pacientes con pancreatitis aguda necrótica y sepsis persistente. Previamente se descartó y erradicó todos los focos infecciosos no pancreáticos. Todos los pacientes con coloración Gram. ó cultivo positivo fueron sometidos a cirugía de inmediato. RESULTADOS: Setenta pacientes con pancreatitis aguda necrótica fueron incluidos, de los cuales 36 (51%) tuvieron pancreatitis aguda necrótica estéril con tratamiento medico conservador y 34 (49%) tuvieron pancreatitis aguda necrótica infectada con tratamiento quirúrgico. El promedio de edad fue 55.19 vs. 57.65 (p=0.57). El promedio de amilasas 1421.74 vs. 1402.45. (p=0.96). El índice de severidad tomográfica fue 8.47 vs. 8.79 (p=0.36).

OBJECTIVE: To determine the prognosis of patients with necrotic acute pancreatitis receiving medical and surgical treatments. SUMMARY: The severe acute pancreatitis treatment is multidisciplinary and requires a daily evaluation of the patient that will allow to observe changes and apply therapy indue time. The treatment includes: Admission in the ICU, fluids, nutrition and antibiotics, as well as other life supports for high-risk patients. Thus, patients undergo conservative treatment or, if it is necessary, surgery. METHODS: A retrospective study of patients with necrotic acute pancreatitis admitted to the ICU between January 2004 and August 2006. The patients with necrotic acute pancreatitis without signs of sepsis underwent a conservative medical treatment, while fine needle punction-aspiration was performed in all patients who were suffering from necrotic acute pancreatitis and persistent sepsis four weeks after their admission and after discarding and eradicating every non-pancreatic focus of infection. All Gram stain or culture positive patients underwent surgery immediately. RESULTS: Seventy patients with necrotic acute pancreatitis were included in the study. Thirty-six patients (51%) suffered acute pancreatitis with sterile necrosis and underwent a conservative treatment, while 34 patients (49%) developed acute pancreatic with infectednecrosis and underwent surgery. The average age was 55.19 vs. 57.65 (p=0.57). The average amylase was 1421.74 vs. 1402.45. (p=0.96). The tomography severity index was 8.47 vs. 8.79 (p=0.36). The Apache II was 8.22 vs. 9 (p=0.46). The average number of failed organs was 0.39 vs. 0.68. (p=0.19). The ICU stay was 10.75 vs. 26.5 days (p < 0.05) while the total hospital stay was 46.47 vs. 57.26 days (p < 0.05). The mortality rate was (3/36) 8.3% vs. (9/34) 26.5% (p < 0.05) for conservative medical treatment vs. surgical treatment, respectively...

Pancreatite necro-hemorrágica: atualização e momento de operar / Necrotizing pancreatitis: update and when to operate

INTRODUÇÃO: A pancreatite necro-hemorrágica representa a variante mais grave do espectro de apresentações clínicas que podem compor o quadro da pancreatite aguda. Embora já conhecida há muitos séculos, inúmeras questões permanecem em aberto acerca dessa entidade e o número de trabalhos sobre o assunto publicados nos últimos anos tem sido muito expressivo. MÉTODO: Foi realizada ampla pesquisa na literatura, com especial atenção aos artigos publicados nos últimos três anos e indexados ao PubMed. Foram utilizados os seguintes descritores de forma cruzada: pancreatitis, surgical procedures; necrosis. A pesquisa inicial evidenciou cerca de 13.000 artigos, sendo avaliados os mais relevantes dos últimos três anos além de artigos mais antigos, considerados "clássicos" sobre o assunto e que, portanto, não poderiam deixar de ser citados. CONCLUSÃO: O tratamento da pancreatite aguda envolve um grande número de questões, dentre as quais as mais importantes estão relacionadas ao manejo da antibioticoterapia, tipo de dieta empregada e as questões relacionadas ao manejo da necrose infectada. Em especial, mudanças radicais foram implementadas nos últimos anos sobre todos esses tópicos, e uma atualização constante deve ser obrigatoriamente buscada pelos profissionais envolvidos no tratamento dessa doença.

BACKGROUND: Necrotizing pancreatitis represents the most severe form of presentation from the clinical spectra of acute pancreatitis. Although known for many centuries, many questions remain open about this entity and a great number of articles were published about this matter in the last few years. METHOD: A throughout research in the literature, with special attention to the articles published in the last three years and indexed to the PubMed was performed. The following headings were used: pancreatitis, surgical procedures, necrosis. The initial research rendered about 13 000 articles, and the ones published in the last three years were evaluated. Some older, but remarkable articles were also included given their importance to this matter. CONCLUSION: The treatment of acute pancreatitis involves a great number of questions, among which the most important are the ones related to the use of antibiotics, type of diet employed and the questions related to the manangement of the infected necrosis. There were many radical changes instituted in the last years on all these topics and a constant updating must be necessarily done by the ones involved on the treatment of this disease.

Rompiendo paradigmas en la Pancreatitis Aguda Grave una nueva visión en el tratamiento de la enfermedad / Breaking paradigms in the acute severe pancreatitis: a new vision in the treatment of the disease

El tratamiento de la pancreatitis aguda grave esta cambiando muy rápido en los últimos tiempos por lo que la actualización constante de las últimas tendencias nos obliga a variar frecuentemente los protocolos de manejo de la enfermedad, ya que lo que hoy es una verdad mañana podría ser un error. En la unidad de pancreatitis aguda grave del Hospital Rebagliati creemos que existen cuatro paradigmas que pueden cambiar nuestra manera de tratar esta enfermedad. En la unidad creemos que la terapia con antibiótico profiláctico no es efectiva paradisminuir la incidencia de necrosis infectada ni la mortalidad en la pancreatitis aguda con necrosis, ya que los trabajos publicados durante los dos últimos años demuestran una clara tendencia a la inefectividad de esta terapia. En el protocolo de la unidad no existe ninguna indicación para intervenir quirúrgicamente a la necrosis estéril. Por lo que el tratamiento quirúrgico podría ser un factor que aumentela severidad del cuadro, produciendo mayores índices de mortalidad en los pacientes con necrosis pancreática estéril. La verdadera y única indicación absoluta de cirugía es la Punción por aguja fina (P.A.F.) positiva, descartando a la ôsepsis en ausencia de foco infeccioso extra pancreático como indicación quirúrgica y dejando a la presencia de gas en la tomografía como indicación relativa para realizar una cirugía. En la Unidad creemos que la necrosectomia pancreática se puede realizar en un solo acto siempre y cuando se pueda retardar el acto quirúrgico el mayor tiempo posible.

The treatment of the severe acute pancreatitis has changed too fast in the last years and the new tendencies and continuous updates are forcing us to constantly vary the disease management protocols taking into account that what is true for today may prove to be a mistake tomorrow. In the Severe Acute Pancreatitis Unit of Eduardo Rebagliati Martins Hospital we believe there are four paradigms that can change the way we treat the disease. In the Unit we believe that a prophylactic antibiotic therapy is not effective in diminishing the incidence of infected necrosis nor in decreasing the death rate among patients with acute pancreatitis with necrosis, since the works published in the last two years make evident the clear tendency to the inefficiency of this therapy. In the protocol of the Unit there is no indication for surgical intervention of sterile necrosis since the surgical treatment could become the factor increasing the severity of the case that would cause higher death rates among patients with sterile pancreatic necrosis. The only and true absolute indication for surgery is a positive fine needle punction whichdiscards ôsepsis in the absence of an extrapancreatic source of infection as surgical indication and allows the presence of gas in the tomography to be a relative indication for surgical intervention. In the Unit we consider that a pancreatic necrosectomy can beperformed in one surgery as long as this can be delayed as much as possible.

Early morphological and functional changes in pancreas following necrosectomy for acute severe necrotizing pancreatitis.

INTRODUCTION: Morphological and functional changes in the pancreas after surgical pancreatic necrosectomy have not been studied extensively. AIMS: To study morphological changes in the pancreas, and exocrine and endocrine pancreatic function following pancreatic necrosectomy. METHODS: Eighteen adult patients surviving at least one month after pancreatic necrosectomy for acute necrotizing pancreatitis were followed up. Contrast-enhanced computed tomography was done every six months. Stool fat was estimated at 3-month intervals, and need for and response to enzyme supplements were recorded. Blood sugar was measured every fortnight; in patients with hyperglycemia, need for oral hypoglycemic agents or insulin was recorded. Additional pancreatic imaging was done in some cases. RESULTS: Six weeks after surgery, nine of 18 patients had exocrine insufficiency. Thirteen patients developed endocrine insufficiency, including 5 who also had exocrine insufficiency. At the end of the study, 13 patients had endocrine insufficiency and 2 had exocrine insufficiency. Pancreatic size was subnormal in all patients at the end of six months. Pancreatography in three cases did not reveal any ductal abnormality. CONCLUSIONS: Necrotizing pancreatitis affects pancreatic exocrine or endocrine function in more than half the patients.

Diagnosis and management of severe acute pancreatitis complicated with abdominal compartment syndrome / 华中科技大学学报（医学）（英德文版）

Presented in this paper is our experience in the diagnosis and management of abdominal compartment syndrome during severe acute pancreatitis. On the basis of the history of severe acute pancreatitis, after effective fluid resuscitation, if patients developed renal, pulmonary and cardiac insufficiency after abdominal expansion and abdominal wall tension, ACS should be considered. Cystometry could be performed to confirm the diagnosis. Emergency decompressive celiotomy and temporary abdominal closure with a 3 liter sterile plastic bag must be performed. It is also critical to prevent reperfusion syndrome. In 23 cases of ACS, 18 cases received emergency decompressive celiotomy and 5 cases did not. In the former, 3 patients died (16.7%) while in the later, 4 (80%) died. Total mortality rate was 33.3% (7/21). In 7 death cases, 4 patients developed acute obstructive suppurative cholangitis (AOSC). All the patients who received emergency decompressive celiotomy 5 h after confirmation of ACS survived. The definitive abdominal closure took place mostly 3 to 5 days after emergency decompressive celiotomy, with longest time being 8 days. 6 cases of ACS at infection stage were all attributed to infected necrosis in abdominal cavity and retroperitoneum. ACS could occur in SIRS stage and infection stage during SAP, and has different pathophysiological basis. Early diagnosis, emergency decompressive celiotomy and temporary abdominal closure with a 3L sterile plastic bag are the keys to the management of the condition.
