ABSTRACT
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.

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.
ABSTRACT
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.

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.(AU)
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.(AU)

ABSTRACT
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.
