Hip fracture registries in low- and middle-income countries: a scoping review.

PURPOSE: The study aims to identify, describe, and organize the currently available evidence regarding hip fracture (HF) registries in low- and middle-income countries (LMICs). METHODS: We conducted a scoping review adhering to PRISMA-ScR guidelines. We searched MEDLINE (PubMed), Google Scholar, Global Index Medicus, websites related to HF, and study references for eligible studies. Two reviewers independently performed the study selection and data extraction, including studies describing the use of individual patient records with the aim to improve the quality of care in older people with HF in LMICs. RESULTS: A total of 222 abstracts were screened, 59 full-text articles were reviewed, and 10 studies regarding 3 registries were included in the analysis. Malaysia and Mexico implemented a HF registry in public hospitals whereas Argentina implemented a registry in the private setting. The Mexican registry, the most recent one, is the only one that publishes annual reports. There was significant variability in data fields between registries, particularly in functional evaluation and follow-up. The Ministry of Health finances the Malaysian registry, while Argentinian and Mexican registries founding was unclear. CONCLUSION: The adoption of HF registries in LMICs is scarce. The few experiences show promising results but higher support is required to develop more registries. Long-term sustainability remains a challenge.

Alliance for the development of the Argentinian Hip Fracture Registry.

Age expectancy has significantly increased over the last 50 years, as well as some age-related health conditions such as hip fractures. The development of hip fracture registries has shown enhanced patient outcomes through quality improvement strategies. The development of the Argentinian Hip Fracture Registry is going in the same direction. INTRODUCTION: Age expectancy has increased worldwide in the last 50 years, with the population over 64 growing from 4.9 to 9.1%. As fractures are an important problem in this age group, specific approaches such as hip fracture registries (HFR) are needed. Our aim is to communicate the Argentinian HFR (AHFR) development resulting from an alliance between Fundación Trauma, Fundación Navarro Viola, and the Argentinian Network of Hip Fracture in the elderly. METHODS: Between October 2020 and May 2021, an iterative consensus process involving 5 specialty-focused meetings and 8 general meetings with more than 20 specialists was conducted. This process comprised inclusion criteria definitions, dataset proposals, website deployment with data protection and user validation, the definition of hospital-adjusted registry levels, implementation planning, and sustainability strategies. RESULTS: By June 2021, we were able to (1) outline data fields, including epidemiological, clinical, and functional dimensions for the pre-admission, hospitalization, discharge, and follow-up stages; (2) define three levels: basic (53 fields), intermediate (85), and advanced (99); (3) identify 21 benchmarking indicators; and (4) make a correlation scheme among fracture classifications. Simultaneously, we launched a fundraising campaign to implement the AHFR in 30 centers, having completed 18. CONCLUSION: AHFR development was based on four pillars: (1) representativeness and support, (2) solid definitions from onset, (3) committed teams, and (4) stable funding. This tool may contribute to the design of evidence-based health policies to improve patient outcomes, and we hope this experience will help other LMICs to develop their own tailored-to-their-needs registries.

Nonintensivist Training to Increase the Staff Capacity of Intensive Care Units During COVID-19 Pandemic Surge in Argentina.

OBJECTIVE: The aim of this study was to report the results of a nationwide critical-care course for non-intensivists to increase staff capacity of intensive care units (ICUs) during the coronavirus disease 2019 (COVID-19) pandemic in Argentina. METHODS: Three academic organizations, with special funding from 55 private companies, developed a short virtual course comprised of Web-based videos, virtual tutorials, and a forum chat. Each state assigned scholarships to non-ICU staff from public hospitals. Students received active follow-up for the completion of the course and took a survey upon course completion. RESULTS: After 4 m, there were 10,123 students registered from 661 hospitals in 328 cities. Of these, 67.8% passed the course, 29.1% were still ongoing, and 3.1% were inactive. Most students were female (74.2%) with a median of 37 y old (IQR 31-44). The group was composed of 56.5% nurses, 36.2% physicians, and 7.4% physiotherapists, of whom 48.3% did not have any experience in critical care. Mean overall satisfaction was 4.4/5 (standard deviation, 0.9), and 90.7% considered they were able to apply the contents to their practice. CONCLUSIONS: This course was effective for rapid training of non-ICU personnel. The assignment strategy, the educational techniques, and the close follow-up led to low dropout and high success rates and satisfaction.

Complicaciones biliares en pacientes con diagnóstico previo de litiasis vesicular sintomática: Comparación entre un hospital público y otro privado del Gran Buenos Aires / Biliary complications in patients with previous diagnosis of symptomatic gallstones: Comparison between a public and a private hospital in Greater Buenos Aires

Antecedentes: la demora en el tratamiento de la litiasis vesicular sintomática (LVS) aumenta el riesgo de complicaciones biliares. Se plantea la hipótesis de que existen diferencias en el tratamiento de la LVS entre el sector público y el de obras sociales del Gran Buenos Aires (GBA). Objetivo: comparar la proporción de pacientes con litiasis biliar complicada (LBC) que presentaban diagnóstico previo de LVS, y evaluar la historia previa de la LBC según la presencia de síntomas y la relación con el sistema de salud. Material y métodos: estudio de corte transversal comparativo entre un hospital público (HPu) y otro privado (HPr) del GBA. Se analizó la historia clínica y se realizó una encuesta a pacientes colecistectomizados por LBC (colecistitis aguda, pancreatitis aguda y coledocolitiasis). Resultados: se incluyeron 105 pacientes del HPu y 136 del HPr. Las características basales difirieron en la edad, nivel educativo, distancia domicilio-hospital y ASA. El diagnóstico previo de LVS fue más frecuente en el HPu (60% vs. 39,7%; p = 0,02), diferencia que se mantuvo luego del ajuste multivariable (OR 2,14; IC 95%: 1,1 a 4,1; p = 0,02). Los pacientes del HPu mostraron una mayor frecuencia de dolores abdominales, tiempo desde el diagnóstico, número de consultas de urgencia luego del diagnóstico y mayor tiempo en lista de espera. Conclusiones: ell HPu mostró mayor pérdida de oportunidad quirúrgica de la litiasis vesicular en un estadio previo no complicado. Las causas podrían ser multifactoriales, pero se necesitan más estudios para corroborar esta hipótesis.

Background: Delays in the treatment of symptomatic cholelithiasis (SCL) increases the risk of biliary complications. There may be differences in the treatment of SCL between the public sector and the social security in the Greater Buenos Aires (GBA). Objectives: The aim of this study was to compare the proportion of patients with complicated gallstone disease (CGD) with previous diagnosis of SCL and to evaluate the history of CGD according to the presence of symptoms and its relation with the health care system. Material and methods: We conducted a cross-sectional study comparing a public hospital (PH) versus a private center (PrH) in the GBA. The clinical records were analyzed and patients with a history of cholecystectomy due to CGD (acute cholecystitis, acute pancreatitis and acute choledocholithiasis) were surveyed. Results: A total of 105 PH patients and 136 PrH patients were included. The baseline characteristics differed in terms of age, educational level, distance from home to hospital and ASA physical status classification. The previous diagnosis of SCL was more common in the PH (60% vs. 39.7%; p = 0.02) and this difference persisted after multivariate adjustment (OR 2.14; 95% CI, 1.1-4.1; p = 0.02). The PH presented more patients with abdominal pain and more visits to the emergency department (ED) after the diagnosis; time after the diagnosis was greater and these patients spent more time on the waiting list. Conclusions: The PH showed greater loss of surgical opportunity of uncomplicated cholelithiasis. This may be due to multiple factors, but further studies are necessary to confirm this hypothesis.

La contemporización biliar percutánea como estrategia en el tratamiento de la lesión quirúrgica de la vía biliar / Percutaneous biliary interventon as an inital treatment for injury of the bile duct

Antecedentes: El drenaje biliar percutáneo (DBP) se ha utlizado para tratar lesiones quirúrgicas de la vía biliar y como complemento de la cirugía de reparación. Objetivo: Presentar los resultados del drenaje biliar percutáneo en una serie consecutiva de pacientes con lesiones quirúrgicas o secuelas de reparaciones quirúrgicas de la vía biliar. Material y Métodos: Se analizaron los pacientes tratados inicialmente mediante DBP. Se utlizó la cla-sificación de Strasberg y se registró: tpo de operación, vía de abordaje, número de reintervenciones, intentos de reparación biliar y presentación clínica. En los pacientes con continuidad bilioentérica, la primera opción fue el tratamiento percutáneo. Se evaluó el DBP en el pre, intra y postoperatorio y pre dilatación percutánea Resultados: En el hospital Argerich, período 2000 a 2014, se incluyeron 76 enfermos, 68.4% mujeres y post colecistectomía 97%. El 77,6% fueron lesiones Tipo E2 a E5. El porcentaje de enfermos con control de síntomas pre cirugía o dilatación percutánea fue: ictericia 59%, colestasis 5%, colangits 91%, fistula biliar 87%, prurito 90%, retro del hepaticostoma o Kehr 91%. En 13 de 16 pacientes con fistula biliar externa se internalizó el catéter biliar a la cavidad abdominal. En el 70% de 52 pacientes operados, el catéter facilitó la identificación de la vía biliar proximal. En el postoperatorio, no hubo fistulas biliares de la anastomosis bilioentérica, y se detectaron 3 pacientes con estenosis biliar residual y 2 con segmentos biliares aislados que fueron tratados. Conclusión: El DBP resulta útl en el preoperatorio, intraoperatorio y postoperatorio de los pacientes con lesiones quirúrgicas biliares.

Background: Percutaneous biliary drainage (PtibD) has been used to treat surgical bile duct injuries and as an adjunct to repair surgery. Objective: To present the results of PtidB in a consecutive series of patents with surgical injuries or sequelae of surgical repairs of the bile duct. Material and methods: Patents initally treated with PtibD were analyzed. Strasberg classificaton was used and recorded: type of operaton, surgical approach, number of reoperatons, biliary repair atempts and clinical presentaton. In patents with bilioenteric continuity, percutaneous biliary treatment was the frst opton. PtibD was evaluated in the pre, intra and postoperative period and in the pre dilataton period. Results: At the Hospital Argerich, from 2000 to 2014, 76 patents were included, 68.4% women and 97% post cholecystectomy. The lesions were Type E2 to E5 in 77% of cases. The percentage of patents with controlled symptoms before surgery or percutaneous dilataton was: jaundice 59%, cholestasis 5%, cholangits 91%, biliary fistula 87%, pruritus 90%, withdrawal hepaticos-toma or T-Kehr 91%. In 13 of 16 patents with external biliary fistula, the catheter could be internalized to abdominal cavity. In 70% of 52 operated patents, the catheter facilitated the identificaton of the proximal biliary duct. In the postoperative period, there were no biliary fistulas of the bilioenteric anastomoses and 3 patents with residual biliary stenosis and 2 with isolated biliary segments were detected and treated. Conclusion: PtibD is helpful in the pre, intra and postoperative treatment of patents with surgical bile duct injuries.

Técnica de reconstrucción laparoscópica en la duodenopancreatectomía cefálica / Laparoscopic reconstructon technique of cephalic duodenopancreatectomy

Antecedentes: la duodenopancreatectomía cefálica (DPC) es la cirugía indicada para el tratamiento de los tumores ampulares y periampulares. El abordaje totalmente laparoscópico es técnicamente dificil de realizar pues requiere mucha destreza y experiencia por parte del equipo quirúrgico. La dificultad técnica de la pancreato-yeyuno anastomosis es quizás el factor limitante para confeccionar la duode-nopancreatectomía cefálica enteramente por vía laparoscópica. Objetivo: mostrar la técnica de reconstrucción laparoscópica con la pancreato-yeyuno anastomosis ductomucosa con la técnica de Blumgart modificada. Lugares de aplicación: Sanatorio de la Trinidad Mitre, Hospital Luciano y Mariano de la Vega, Hospital Argerich. Material y Métodos: se analizaron los pacientes operados enteramente por vía laparoscópica. Dichos pacientes fueron reconstruidos con una sola asa, realizando una pancreato-yeyuno anastomosis con la técnica de Blumgart modificada. Resultados: en los pacientes con DPC totalmente laparoscópica, el páncreas fue de textura intermedia en 3 pacientes y en 2 con textura blanda. El tempo operatorio medio fue 384 minutos. La estadía hospitalaria media fue 12 días. Dos pacientes desarrollaron fistula pancreática tipo A. Un paciente presentó retardo del vaciamiento gástrico que resolvió espontáneamente. Conclusiones: la reconstrucción completa por vía laparoscópica es factble y totalmente reproducible con la misma técnica que se utliza por vía laparotómica.

Background: pancreatoduodenectomy is the procedure indicated for the treatment of ampullary and periampullary tumors. The total laparoscopic approach for pancreatoduodenectomy is technically dificult to perform requiring skill and great experience of the surgical team. The technical dificulty of the pancreatojejunostomy is perhaps the limiting factor to perform the pancreatoduodenectomy totally laparoscopic. Objective: to describe the technique of the laparoscopic reconstructon using the pancreatojejunos-tomy according to the Blumgart modifed technique. Material and methods: patentis operated entrely by totally laparoscopic approach were analyzed. These patentis were reconstructed performing a pancreatojejunostomy with the Blumgart modifed technique. Resultis: in patentis with totally laparoscopic approach, pancreas texture was intermediatein 3 pa-tentis and 2 had sof texture. The average operating tme was 384 minutes. The average hospital stay was 12 days. Two patentis developed pancreatic fistula type A. One patent had delayed gastric emp-tying which resolved spontaneously. Conclusion: total laparoscopic reconstructon is feasible and reproducible with the same technique used by laparotomy.

Diagnóstico y tratamiento de la pancreatitis aguda en la Argentina. Resultados de un estudio prospectivo en 23 centros.

In Argentina there are no multicenter studies evaluating the management of patients with acute pancreatitis (AP) nationwide. OBJECTIVES: The main objective of this study is to know how the patients with AP are treated in Argentina. The secondary objective is to assess whether the results comply with the recommendation of the American College of Gastroenterology Guide. MATERIAL AND METHODS: Twenty three center participated in the study. They include in a database hosted online consecutive patients with acute pancreatitis from june 2010 to june 2013. RESULTS: 854 patients entered the study. The average age was 46.6 years and 495 (58%) belonged to the female sex. The most common cause (88.2%) of AP was biliary. Some prognostic system was used in 99 % of patients and the most used was Ranson (74.5%). Were classified as mild 714 (83.6%) patients and severe 140 (16.4%). Systemic complications occurred in 43 patients and local complications in 21. 86 patients underwent dynamic CT scans and 73 patients had pancreatic and / or peripancreatic necrosis. Mortality was 1.5%. There was no difference in mortality in relation to the size, complexity or affiliation of the center. The comply of key recommendations of the American College of Gastroenterology Guide was over 80%. CONCLUSIONS: The diagnosis and treatment of patients with AP in 23 health centers located throughout the country was optimal. The management complied with most of the recommendations of the American College of Gastroenterology Guide.

Laparoscopic hepaticojejunostomy and gastrojejunostomy for palliative treatment of pancreatic head cancer in 48 patients.

INTRODUCTION: Approximately 80% of patients with pancreatic cancer are not candidates for curative resection at the time of diagnosis. The objective of this study is to show that although endoscopic treatment is the standard palliation, surgical laparoscopic treatment is both feasible and effective for these patients. MATERIALS AND METHODS: Preoperative resectability was evaluated by dynamic contrast-enhanced computed tomography scans. Endoscopic palliation was the first choice for patients with metastatic disease and for patients with locally advanced pancreatic cancer with bad performance status. Laparoscopic surgical palliation was indicated for patients with jaundice and locally advanced pancreatic cancer (elective palliation) and for patients with jaundice with metastatic disease and failure in the endoscopic/percutaneous treatment (necessary palliation). Elective palliation consisted of Roux-en-Y hepaticojejunostomy and gastrojejunostomy and necessary palliation consisted of laparoscopic hepaticojejunostomy alone. RESULTS: A total of 48 patients received laparoscopic surgical palliation. Morbidity rate was 33.3% and mortality was 2.08%. There was no need for late surgeries in any of the patients. CONCLUSION: Surgical laparoscopic palliation is a feasible treatment option for locally advanced pancreatic cancer. Even though metallic stents are still the best palliation method for patients with systemic disease, if stents fail, the laparoscopic approach is a viable treatment.

Schloffer's tumor: Case report and review of the literature.

INTRODUCTION: The so-called Schloffer tumor (ST) is a rare inflammatory pseudotumor. It usually appears several years after abdominal surgery or trauma. PRESENTATION OF CASE: A 32-year-old man was referred to our hospital complaining of a painful mass in the left hypochondrium, postprandial distension and a weight loss of about 14kg. He had had a left inguinal hernioplasty without mesh the previous year. Ultrasonography of the abdomen showed a 2cm×2cm hypoechoic lesion in contact with the abdominal wall. Computerized tomography of the abdomen showed a heterogeneous mass in the great omentum. Laparoscopic exploration revealed an omental mass firmly attached to the abdominal wall. A great deal of purulent fluid spread during the procedure. Due to the difficult exploration, the procedure converted to hand assisted laparoscopy. We find an omental tumor involving the stomach and the transverse colon. Inside the mass there were purulent material and non-absorbable sutures. A drain was left inside the cavity of the abscess. Histological examination showed chronic inflammation. DISCUSSION: ST characteristically presents a central chronic abscess containing non-absorbable sutures. It has been described after appendectomy, hernioplasty, hysterectomy, gastrectomy or colonic resections. Although benign, its progressive growth and infiltrating behavior resemble malignant tumors. CONCLUSION: We suggest that a mini-invasive approach should always be performed. The interesting thing about this case is the appearance of the tumor in a place far away from the previous surgical site. A simple drainage and removal of suture material solves the problem of these patients.

Changes in gastrosplenic circulation and splenic function after distal pancreatectomy with spleen preservation and splenic vessel excision.

INTRODUCTION: Distal pancreatectomy with spleen preservation and splenic vessel excision is a commonly used technique. However, it produces significant gastrosplenic circulation and splenic function changes. PURPOSE: The aim of this work was to determine the immediate consequences on gastrosplenic circulation, late consequences on splenic function, and development of varicose veins. METHODS: Thirty-five patients with pancreatic tumors and anatomical feasibility were included. Preoperative splenic circulation was evaluated by dynamic contrast-enhanced computed tomography (CT) scans. Early splenic perfusion was assessed by CT 7 days after surgery and late changes in gastrosplenic circulation 6 months after surgery. Varicose veins were evaluated by CT and endoscopy 6 months after surgery. Pitted cells and Howell-Jolly bodies were used as markers of splenic function. Postoperatory findings included changes in splenic perfusion 7 days and 6 months after surgery, development of varicose veins on CT scans and endoscopy, and detection of markers of splenic hypofunction on blood smears. RESULTS AND CONCLUSION: Seven days after surgery, 63% of patients had some degree of splenic hypoperfusion, and 6 months after surgery, 83% of patients had normal perfusion. CT scans showed varices in 26 patients, and endoscopy revealed varicose veins in 11. Two patients experienced bleeding; markers of splenic hypofunction were found in 59% of cases.

Early oral feeding versus traditional postoperative care after abdominal emergency surgery: a randomized controlled trial.

BACKGROUND: Early oral feeding (EOF) has been demonstrated to be safe and beneficial after abdominal elective surgery. The aim of this randomized controlled trial is to assess the safety and benefits of EOF compared to traditional postoperative care (TPC) after abdominal emergency surgery. METHODS: Patients assigned to the EOF group commenced a soft diet within 24 h after surgery. In the TPC group, a liquid diet was commenced upon passage of flatus or stool and then advanced to soft food. The primary endpoint was the complication rate. Secondary endpoints were severity of complications, mortality, gastrointestinal leaks, surgical-site infection, reoperation, diet intolerance, time to first flatus and stool, amount of food intake, postoperative discomfort, hospital stay, weight loss at the 15th postoperative day and incisional hernias. RESULTS: A total of 295 patients assigned to EOF (n = 148) or TPC (n = 147) were analyzed. No significant differences were seen in the complications rates (EOF 45.3 % vs. TPC 37.4 %; p = 0.1). There was a significantly higher rate of vomiting with EOF (EOF 13.5 % vs. TPC 6.1 %; p = 0.03), with no differences in nasogastric tube reinsertion. EOF patients' food intake was proportionally lower for the first three meals than that of TPC patients (p < 0.01). Postoperative discomfort survey revealed more hunger in the TPC group (p < 0.01). There were no differences in postoperative ileus or length of hospital stay. CONCLUSIONS: EOF was safe after abdominal emergency surgery. EOF was associated with more vomiting (treated easily and without patient discomfort) and less hunger than with TPC. No other EOF-related benefits could be demonstrated during this trial.

Factores determinantes de evolución en pacientes operados por complicaciones locales de la pancreatitis aguda

Antecedentes: La necrosis pancreática infectada y el seudoquiste son complicaciones que en general requieren algún tipo de tratamiento quirúrgico (laparoscópico, percutáneo o convencional). Objetivo: Identificar los factores determinantes de mortalidad en pacientes sometidos a cirugía por complicaciones locales de la pancreatitis aguda. Método: Se realizó una búsqueda bibliográfica en la National Library of Medicine mediante Pubmed limitada a los trabajos publicados en inglés, a partir de 1990 utilizando los siguientes términos solos o en combinación: "pancreatic necrosis", "necrosectomy", "mortality", "morbidity","local complications", "surgery"y "severe acute pancreatitis". En la base de datos LILACS se realizó también una búsqueda de los trabajos publicados en Argentina, en el período 2000 a 2011. Resultados: Se seleccionaron 119 trabajos y se excluyeron 82 por inadecuado análisis estadístico o insuficiente número de pacientes. Del análisis de los 37 trabajos seleccionados se identificaron 6 factores determinantes de mortalidad luego de la necrosectomía pancreática. Estos factores fueron: el intervalo de tiempo entre el ingreso y la necrosectomía, la composición líquida o sólida predominante, la presencia de infección, la extensión y localización de la necrosis pancreática, la presencia de disfunciones orgánicas y la organización de la necrosis. En la búsqueda de la base de datos LILACS se identificaron 7 trabajos publicados sobre cirugía de las complicaciones locales de la pancreatitis aguda. Conclusión: La bibliografía puede identificar seis factores determinantes de evolución en los pacientes sometidos a cirugías por complicaciones locales de la pancreatitis, lo cual tiene utilidad para el tratamiento.

Background: Infected pancreatic necrosis and pseudocyst are complications that, generally, require any type of surgical treatment (laparoscopic, percutaneous or open surgery). Objective: To identify mortality factors in patients who underwent surgery for local complications of acute pancreatitis. Method: It was conducted a literature search in the National Library of Medicine through Pubmed, limited to publications in English since 1990, using the following keywords: pancreatic necrosis, necrosectomy, mortality, morbidity local complications, surgery and severe acute pancreatitis. In the data base LILACS a similar search was conducted, limited to the Argentine literature, during the period 2000 - 2011. Results: 119 publications were selected and 82 were excluded because of inadequate statistical analysis or insufficient number of patients. After the analysis, 37 publications were selected and 6 mortality factors after pancreatic necrosectomy were identified. These factors were: time between admission and necrosectomy; predominance of liquid orsolid components; presence of infection; extensión and localization of pancreatic necrosis; presence of organ failure and walled off necrosis. In the search conducted in the LILACS data base, 7 publications about surgery of the local complications of acute pancreatitis were identified. Conclusión: After the literature search, six factors were identified related to the patient evolution after surgery for pancreatic local complications.

Pancreatitis aguda recurrente por neoplasia intraductal papilomucinosa tipo II: Racionalidad del tratamiento mediante resección del quiste guiada por ecografía / Acute pancreatitis appellant by intraductal neoplasis papilomucionsa type II: Rationality of the treatment by means of resection of the cyst guided by ecography

Antecedentes: La neoplasia intraductal papilomucinosa de páncreas (NIPM) tipo II, localizada en el páncreas ventral puede ser causa de pancreatitis aguda recurrentes. No existen publicaciones sobre los resultados del tratamiento quirúrgico. Objetivo: Evaluar los resultados de DPC en esta situación clínica y discutir la racionalidad de la resaección guiada por ecografía intraoperatoria de la lesión quística. Lugar: Hospital público de nivel terciario. Diseño: Estudio prospectivo. Población: Pacientes con NIPM tipo II del páncreas ventral diagnosticada por colangiopan-creatorresonancia y al menos 2 ataques de pancreatitis aguda durante el último año. Métodos: Fueron operados 7 pacientes, todos varones con 58 años de edad media y lesión quística del páncreas ventral ( tamaño medio: 1,6 cm). Cinco de ellos recibieron una DPC y 2 una resección de la lesión quística guiada por ecografía. Resultados: De los 5 pacientes que recibieron una DPC, 2 presentaron recurrencia, al año y a los 4 años respectivamente. En ambos casos existía una obstrucción de la anastomosis pancreatoyeyunal y ninguno presentaba recidiva de la NIPM. Los 3 pacientes restantes no presentaron recurrencia aunque uno murió al año por causa no relacionada. Los 2 pacientes tratados mediante resección local no presentaron recidiva durante los primeros 4 y 8 meses de la cirugía. Conclusiones: Los resultados de la DPC en la pancreatitis recurrente poe NIPM no son aceptables. La resección del quiste guiada por ecografía es una técnica factible que respeta la anatomía del conducto pancreático y podría prevenir definitivamente la pancreatitis, aunque se requiere más tiempo para evaluar sus resultados.

Pediatric thoracoscopic training in an experimental pleural empyema rabbit model.

BACKGROUND: Thoracoscopy has proved to be effective in the treatment of stage 2 (fibrinopurulent) empyema, but this technique requires different abilities from those needed in open surgery. The aim of this study is to evaluate the usefulness of an experimental empyema in rabbits as a thoracoscopic training model. MATERIALS AND METHODS: Twenty New Zealand rabbits were anesthetized with acepromazine and ketamine. A Veress needle was introduced into the pleural space, and a turpentine and saline solution were injected. Twenty-four hours later, 1016 colony-forming units of Escherichia coli and 1 g of agar in 1 mL of saline solution were injected. The rabbits were operated on 96 hours after bacterial injection by 30 pediatric surgeons attending a hands-on pediatric laparoscopic course. The contralateral lung was selectively intubated and three ports were placed to perform an empyema debridement. The surgeons evaluated the model using subjective criteria from an evaluation form. RESULTS: One animal died (5%) and 2 (10%) did not form empyema. The other 17 rabbits (85%) presented with a fibrinopurulent empyema. All usual surgical steps could be performed. As regards the surgeons' opinion of the model, 23 (76.7%) considered it very good while 7 (23.3%) thought it was good. Twenty-three (76.7%) answered that the empyema stage was correct for thoracoscopic treatment. CONCLUSION: As reflected by our experience and the survey completed by the 30 pediatric surgeons, this empyema model in rabbits is very useful for thoracoscopic training.
