PEComa pancreático ¿una neoplasia no tan infrecuente? Revisión sistemática y actualización clínico-terapéutica / Pancreatic PEComa, a not so uncommon neoplasm? Systematic review and therapeutic update

Los PEComas pancreáticos son neoplasias con potencial maligno extremadamente raras, que afectan mayoritariamente a mujeres de mediana edad y que se caracterizan por presentar marcadores melanocíticos y miogénicos en el análisis inmunohistoquímico. No existen síntomas ni pruebas de imagen patognomónicas. El diagnóstico se establece con el análisis de la pieza quirúrgica o de la PAAF obtenida con ecoendoscopia preoperatoria. El tratamiento más habitual consiste en la exéresis radical, adecuando la intervención a la localización del tumor. Hasta la fecha se han descrito 34 casos, no obstante, más del 80% de los mismos han sido reportados en la última década, lo que sugiere que es una patología más frecuente de lo esperado. Se reporta un nuevo caso de PEComa pancreático y se realiza una revisión sistemática de la literatura de acuerdo con las guías PRISMA con el objetivo de difundir su existencia, profundizar en su conocimiento y actualizar su manejo (AU)

Pancreatic PEComas are extremely rare neoplasms with malignant potential, which mostly affect middle-aged women and are characterized by presenting melanocytic and myogenic markers in immunohistochemical analysis. There are no symptoms or pathognomonic imaging tests, so the diagnosis is established with the analysis of the surgical specimen or the FNA obtained with preoperative endoscopic ultrasound. The mean treatment consists on radical excision, adapting the intervention to the location of the tumor. To date, 34 cases have been described; however, more than 80% of them have been reported in the last decade, which suggests that it is a more frequent pathology than expected. A new case of pancreatic PEComa is reported and a systematic review of the literature is carried out according to the PRISMA guidelines with the aim of divulge this pathology, deepening its knowledge and updating its management (AU)

Are reactive C protein and procalcitonin useful for early diagnosis of postoperative intraabdominal infection after pancreaticoduodenectomy for pancreatic cancer?

OBJECTIVE: To evaluate the relationship between C reactive protein and procalcitonin levels and the appearance of post-operative intraabdominal infection, in patients with pancreaticoduodenectomy due to pancreatic cancer. METHOD: A prospective observational study, including 35 patients, was made. Procalcitonin and C reactive protein were measured before surgery, as well as 24, 48 and 72 h after the surgical procedure. Patients were divided in two groups, with and without intraabdominal infection. RESULTS: Six patients (17.1%) presented post-operative intraabdominal infection. Both, procalcitonin and C reactive protein, increased in all patients after surgery, but there were no significant differences between the two groups. However, the ratio between the C reactive protein concentrations on post-operative day 3 and the concentrations on post-operative day 1 was significantly increased in the group of patients with intraabdominal infection. The predictive positive value and the predictive negative value for this ratio were 60% and 95%, respectively, for a cut-off point of 2.3. CONCLUSIONS: The ratio between C reactive protein value on post-operative day 3 and the value on post-operative day 1 is a good predictor of post-operative intraabdominal infection after pancreaticoduodenectomy.

OBJETIVO: Evaluar la relación entre los valores de proteína C reactiva y de procalcitonina y la aparición de infección intraabdominal posoperatoria en pacientes con duodenopancreatectomía por cáncer de páncreas. MÉTODO: Estudio prospectivo observacional que incluye 35 pacientes. Ambos parámetros se midieron antes de la cirugía y a las 24, 48 y 72 horas de la intervención. Los pacientes se dividieron en dos grupos: con y sin infección intraabdominal. RESULTADOS: Seis pacientes (17.1%) tuvieron infección intraabdominal. Ambos parámetros aumentaron en todos los pacientes tras la cirugía, pero no hubo diferencias significativas entre los dos grupos. Sin embargo, el cociente entre los valores de proteína C reactiva en el día 3 y los valores en el día 1 de posoperatorio era significativamente mayor en los pacientes con infección intraabdominal, con un valor predictivo positivo del 60% y un valor predictivo negativo del 95%, para un punto de corte de 2.3. CONCLUSIONES: El cociente entre las concentraciones séricas de proteína C reactiva en el tercer día y en el primer día de posoperatorio es un buen predictor de infección intraabdominal posoperatoria después de una duodenopancreatectomía.

Clinical Outcomes of Elective Laparoscopic Cholecystectomy: Retrospective Comparative Study Between Patients With and Without Xanthogranulomatous Cholecystitis.

AIM: The aim of this study was to evaluate the results of laparoscopic cholecystectomy (LC) in patients with xanthogranulomatous cholecystitis (XGC) compared with patients without XGC. METHODS: A retrospective study was performed including patients who had undergone elective LC between January 2003 and November 2017. Results of patients with XGC (25) were compared with those of patients without XGC (2181) with respect to operative time, conversion rate, drain use, postoperative complications, and postoperative stay. RESULTS: The mean operative times in patients with and without XGC were 112.8 and 66.3 minutes, respectively (P=0.001). The conversion rate was 36% in patients with XGC and 3.89% in patients without XGC (P=0.001). Drains were used in 76% of patients with XGC and in 24% of patients without XGC (P=0.001). Postoperative complication rate was 16% and 9.9% in patients with and without XGC, respectively (P=0.309). Mean postoperative stays in patients with and without XGC were 4.3 and 2.3 days, respectively (P=0.001). CONCLUSIONS: LC in patients with XGC is associated with significantly longer operative time, higher conversion rate, greater drain use, and longer postoperative stay compared with patients without XGC.

Esophagogastric pathology in morbid obese patient: Preoperative diagnosis, influence in the selection of surgical technique.

INTRODUCTION: Given the difficulty in accessing to the excluded stomach after gastric bypass and the increase in gastroesophageal reflux after sleeve gastrectomy, it is justified to perform a preoperative fibrogastroscopy.The influence of the fibrogastroscopy (FGS) findings in the therapeutic approach is analyzed. PATIENTS AND METHODS: A retrospective study of preoperative FGS findings is performed, from 04/06 to 12/12. The influence of the FGS results on the surgical technique selection, in the endoscopic or medical treatment and its relation to gastric fistula is analyzed by means of multivariate regression (confounding factors: Age, body mass index, arterial hypertension, diabetes mellitus, antiplatelet therapy, surgical technique (bariatric surgery, sleeve gastrectomy). RESULTS: Three hundred thirty one patients are included: 32.6% biopsy of gastric lesion; 27% gastritis; 18.1% hiatal hernia; 3% metaplasia; 0.6% Barrett esophagus; 2.1% esophagitis; 0.3% dysplasia; 0.3 Schatzky´s ring; 1.5% incompetent cardia; 2.4% duodenitis; 0.3% gastric erosions; 0.6% gastric xanthoma; 1.8%, gastric polyp; 1.6% duodenal ulcer; 0.6% papulo-erosive gastritis; 0.6% esophageal papilloma; 0.3% submucosal tumor. Helicobacter pylori+ 30.2% (triple therapy eradication in all patients). The FGS findings led to a variation in the surgical technique or to the completion of endoscopic treatment in 22.2% of cases.The gastric lesions did not influence the development of gastric fistula. Independent prognostic factors of fistula: Sleeve gastrectomy (7.9% vs. 2.7%; p = 0.02; OR: 1.38 IC95: 1.01-1.87) and the body mass index > 50 kg/m2) (6.7% vs. 2.2%; p = 0.04; OR: 3.7 IC95: 1.12-12.4). CONCLUSIONS: The diagnosis of gastroesophageal disease through preoperative FGS motivated variations in the therapeutic approach in 52% of patients, so we consider essential to include the preoperative FGS in bariatric surgery.

Procalcitonina y proteína C reactiva como marcadores precoces de infección intraabdominal postoperatoria en pacientes operados de cáncer gastrointestinal / Procalcitonin and C-reactive protein as early indicators of postoperative intra-abdominal infection after surgery for gastrointestinal cancer

OBJETIVO: Evaluar la asociación entre niveles séricos de procalcitonina (PCT) y proteína C reactiva (PCR), en los 3 primeros días de postoperatorio, y la aparición de infección intraabdominal postoperatoria. MÉTODO: Estudio observacional prospectivo que incluye a 67 pacientes intervenidos quirúrgicamente de cáncer colorrectal, gástrico y pancreático. Los niveles séricos de PCT y PCR se midieron antes de la cirugía y a las 24, 48 y 72 h de la misma. Se registraron los valores de PCT y PCR, así como su fiabilidad para la detección de infección intraabdominal postoperatoria. RESULTADOS: La incidencia de infección intraabdominal postoperatoria fue de 13,4%. Los valores de PCR a las 72 h, los valores de PCT a las 24, 48 y 72 h y el cociente entre el valor de PCR a las 72 h y el valor de PCR a las 48 h (PCR D3/PCR D2) se asociaron significativamente con la aparición de infección intraabdominal postoperatoria. La sensibilidad más alta correspondió al valor de PCT a las 72 h (88,9%); la especificidad más alta y el valor predictivo positivo (VPP) más alto, al cociente PCR D3/PCR D2 (96,49 y 71,4%, respectivamente); el valor predictivo negativo (VPN) más alto, al valor de PCT a las 72 h y a las 24 h (97,7 y 96%, respectivamente). CONCLUSIÓN: Los valores de PCT se asocian significativamente con la aparición de infección intraabdominal postoperatoria en los 3 primeros días de postoperatorio. Su sensibilidad y VPP son bajos, pero su VPN es alto, incluso a las 24 h de la cirugía

AIM: to evaluate the association between serum levels of procalcitonin and C-reactive protein, on the first 3 postoperative days, and the appearance of postoperative intra-abdominal infection. METHOD: Prospective observational study including 67 patients operated on for colo-rectal, gastric and pancreatic cancer. Serum levels of procalcitonin and C-reactive protein were analyzed before surgery and daily until the third postoperative day. Values of procalcitonin (PCT) and C-reactive protein (CRP) were recorded as well as their accuracy for detection of postoperative intra-abdominal infection (PIAI). RESULTS: The incidence of postoperative intra-abdominal infection was 13.4%. CRP serum levels at 72 h, PCT serum levels at 24, 48 and 72 h and the ratio between serum levels of CRP at 72 hours and serum levels of CRP at 48 hours (CRP D3/CRP D2) were significantly associated with the appearance of postoperative intra-abdominal infection. The highest sensitivity corresponded to PCT at 72 hours (88.9%); the highest specificity and positive predictive value corresponded to the ratio CRP D3/CRP D2 (96.49% and 71.4%, respectively); the highest negative predictive value to procalcitonin at 72 h and 24 h. CONCLUSIONS: Serum levels of PCT are significantly associated with the appearance of postoperative intra-abdominal infection. Sensitivity and predictive positive values are low, but negative predictive value is high, even at 24 h after surgery

[Is the morbid obesity surgery profitable in times of crisis? A cost-benefit analysis of bariatric surgery]. / ¿Es rentable operar a los obesos mórbidos en tiempos de crisis? Análisis coste-beneficio de la cirugía bariátrica.

Morbid obesity is a serious health problem whose prevalence is increasing. Expensive co-morbidities are associated to these patients, as well as a reduction in the survival. Bariatric surgery resolves the co-morbidities (type 2 diabetes mellitus, 86.6%; cardiovascular risk, 79.0%; obstructive sleep apnea syndrome, 83.6%; hypertension, 61.7%), reduces the mortality rate (among 31-40%), and increases the morbid obese patients survival over a 10-years period. It provides significant savings for the National Health System. The obese patients consume a 20% plus of health resources and 68% plus of drugs than general population. Bariatric surgery requires an initial investment (diagnosis-related group cost: 7,468 €), but it is recovered in a cost-effectiveness ratio of 2.5 years. Significant savings are obtained from the third year. To the direct economic benefits associated with reduced health expenditures it should be added an increase in tax collection (sick leave and unemployment reduction is estimated in 18%, with a productivity increase of 57% for self-employed people). Bariatric surgery is one of the most cost-effective procedures in the healthcare system.
