RESUMO
OBJECTIVE: Intra-abdominal septic complications (IASC) affect short-term outcomes after surgery for colon cancer. Blood transfusions have been associated with worse short-term results. The role of IASC and blood transfusions on long-term oncologic results is still debated. This study aims to assess the impact of these two variables on survival after curative colon cancer resection. PATIENTS AND METHODS: Retrospective analysis of a prospectively maintained database of patients who underwent curative surgery for colon cancer at a university hospital, between 1993 and 2010. Cox regression was used to identify the role of IASC and transfusions (alone and combined) on local recurrence (LR), disease-free survival (DFS), and cancer-specific survival (CSS). RESULTS: Out of the 1686 patients analyzed, 1277 fit in the inclusion criteria. Colorectal surgeons performed the procedure in 82.2% of the patients. Blood transfusions were administered to 25.8% of the patients. Thirty-day complication and mortality rates were 34.5% and 6.1%. IASC occurred in 9.9%. The mean follow-up was 66 months. The 5-year rates of LR, DFS, and CSS were 7%, 79.8%, and 85.1%. The year of surgery and pT (Hazard ratio 9.35, 95% CI 1.23-70.9, for T4) and pN (Hazard ratio 2.57, 95% CI 1.39-4.72, for N2) stages were independent risk factors for LR. The same variables, bowel obstruction and surgeries performed by surgeons not specialized in colorectal surgery, were also associated with worse DFS and CSS. IASC and blood transfusions were not associated with LR, DFS, and CSS, whether alone or combined. CONCLUSIONS: IASC and transfusions were not associated with worse oncological outcomes after curative colon cancer surgery per se. Other factors were more important predictors of survival.

INTRODUCTION: Anastomotic leak (AL) is a serious complication in colorectal surgery due to its increase in morbidity and mortality. The aim of this prospective non-randomised study is to determine whether C-reactive Protein (CRP) is useful as a predictor of AL in patients undergoing open versus laparoscopic surgery. METHODS: A total of 168 patients undergoing elective colorectal surgery were included. CRP was measured daily during the first 5postoperative days. Complications, specially AL, were analysed. RESULTS: Following an open approach 32 patients (45.7%) presented complications, 15 (18.7%) in the laparoscopic group and 12 (29.4%) in the converted group (P=0.153). Following open surgery 9 patients experienced AL, 5 were detected in the laparoscopic group and none in those converted (P=0.153). There were significant differences in CRP values between the 3 groups (P=0.03). ROC Curves showed AUC for the open and laparoscopic approach of 0.731 and 0.760 respectively. On day 4 the AUC was 0.867 for the open group and 0.914 for the laparoscopic group. Cut-off points on day 4 were: Open: 159.2mg/L; sensitivity 75%, specificity 89% and NPP 96% (P<0.001). Following laparoscopic surgery the cut-off point was 67.3%; sensitivity 100%, specificity 89.5% and NPP 100% (P=0.016). CONCLUSION: CRP on day 4 is useful to diagnose AL. Different cut-off values should be taken into account depending on the approach used.

INTRODUCTION: Living donor liver transplantation (LDLT) is an alternative to conventional transplantation given its excellent results. The aim of this study is to evaluate long-term outcomes in LDLT recipients. METHODS: 100 consecutive THDV recipients from the Hospital Clínic of Barcelona from March 2000 to October 2015 were included. The main indication for transplantation was end-stage liver disease (58%) followed by hepatocellular carcinoma (41%). 95% of grafts consisted of the right liver of the donor and the 5% of the left liver. RESULTS: After a median follow-up of 65.5 months, patient and graft survival at 1, 3, and 5 years was 93%, 80% and 74% and 90%, 76%, and 71%, respectively. The overall re-transplant rate was 9%. The most common long-term complication was biliary stenosis (40%) with an average time of onset of 13.5±12 months, with repeated admissions and an average of 1.9±2 endoscopic procedures and 3.5±3 Radiological procedures per patient. The definitive treatment was radiological dilation in 40% of cases, surgical intervention in 22.5% and re-transplantation in 7.5%. CONCLUSIONS: Given the long-term results, LDLT is confirmed as an alternative to conventional transplantation. However, the high rate of late biliary complications involves repeated admissions and invasive treatments that, while not compromising survival, can affect the patient's quality of life.

OBJECTIVES: To analyze the safety and efficacy of percutaneous placement of coated self-expanding metallic stents (SEMS) in patients with biliary leaks. MATERIAL AND METHODS: This ethics committee at our center approved this study. We retrospectively reviewed all coated SEMS placed between October 2008 and September 2015. We analyzed patient-related factors such as the primary underlying disease, prior hepatic procedures, and clinical outcome. We evaluated the location, the number and type of leak (anastomotic or non-anastomotic), and the characteristics of the interventional procedure (number of stents deployed, location of the stents, technical success, and primary functionality). We recorded the complications registered. RESULTS: We studied 14 patients (11 men and 3 women). The mean follow-up period was 375.5 days (range 15-1920 days). Leaks were postsurgical in 12 patients. One patient developed an arteriobilioportal fistula. In another, the biliary leak occurred secondary to the rupture of the common bile duct after ERCP. A total of 23 coated SEMS were placed, including 21 Fluency® stents (Bard, Tempe, AZ, USA) and 2 Wallflex® stents (Boston Scientific, Galway, Republic of Ireland). The technical success of the procedure was considered total in 11 (78.6%) patients, partial in 2 (14.3%) patients, and null in 1 (7.2%) patient. The clinical outcome was good in 13 of the 14 patients. The mean period of primary functionality of the coated SEMS was 331 days (range 15-1920 days). No major complications were observed in 11 (78.6%) patients. CONCLUSIONS: Percutaneous placement of coated SEMS for the treatment of benign biliary leaks is safe and efficacious, with a high rate of technical and clinical success and a moderate rate of complications.

OBJECTIVE: Clinical management of dengue relies on careful monitoring of fluid balance combined with judicious intravenous (IV) fluid therapy. However, in patients with significant vascular leakage, IV fluids may aggravate serosal fluid accumulation and result in respiratory distress. METHODS: Trained physicians followed suspected dengue cases prospectively at seven hospitals across Asia and Latin America, using a comprehensive case report form that included daily clinical assessment and detailed documentation of parenteral fluid therapy. Applying Cox regression, we evaluated risk factors for the development of shock or respiratory distress with fluid accumulation. RESULTS: Most confirmed dengue patients (1524/1734, 88%) never experienced dengue shock syndrome (DSS). Among those with DSS, 176/210 (84%) had fluid accumulation, and in the majority (83%), this was detectable clinically. Among all cases with clinically detectable fluid accumulation, 179/447 (40%) were diagnosed with shock or respiratory distress. The risk for respiratory distress with fluid accumulation increased significantly as the infused volume over the preceding 24 h increased (hazard ratio 1.18 per 10 ml/kg increase; P < 0.001). Longer duration of IV therapy, use of a fluid bolus in the preceding 24 h, female gender and poor nutrition also constituted independent risk factors. CONCLUSIONS: Shock and respiratory distress are relatively rare manifestations of dengue, but some evidence of fluid accumulation is seen in around 50% of cases. IV fluids play a crucial role in management, but they must be administered with caution. Clinically and/or radiologically detectable fluid accumulations have potential as intermediate severity endpoints for therapeutic intervention trials and/or pathogenesis studies.

INTRODUCTION: Anastomotic leakage (AL) is one of the most feared postoperative complications in colon cancer surgery due to an association with increased morbidity and mortality, although its impact on long-term survival is not consensual. The aim of this study was to investigate the influence of AL on long-term survival of patients undergoing curative colon cancer resection. METHODS: A single-centre retrospective cohort study was designed. Clinical records of all consecutive patients undergoing surgery at our institution between 01/01/2010 and 12/31/2019 were reviewed. Survival analysis was performed by Kaplan-Meier method to estimate overall and conditional survival and Cox regression to search for risk factors impacting survival. RESULTS: A total of 2351 patients submitted to colorectal surgery were screened for eligibility, of which 686 with colon cancer were included. AL occurred in 57 patients (8,3%) and was associated with higher postoperative morbidity and mortality, length of stay and early readmissions (P < 0,05). Overall survival was inferior in the leakage group (Hazard Ratio 2,08 [1,02-4,24]). Conditional overall survival at 30, 90 days and 6 months was also inferior in the leakage group (P < 0,05), but not at 1 year. Risk factors independently associated with reduced overall survival included AL occurrence, higher ASA classification and delayed/missed adjuvant chemotherapy. AL did not impact local and distant recurrence (P > 0,05). CONCLUSION: AL has a negative impact on survival. Its effect is more pronounced on short-term mortality. AL does not appear to be associated with disease progression.

OBJECTIVES: To analyze the results obtained in terms of efficacy and safety during the learning curve of a surgical team in the technique of laparoscopic common bile duct exploration with cholecystectomy (LCBDE+LC) using choledochoscopy for the treatment of patients with cholelithiasis and choledocolithiasis or common bile duct stones (CBDS) (CDL). METHODS: Single-center prospective analysis of patients treated with LCBDE+LC during the first 4 years of implementation of the technique. A descriptive and comparative analysis was carried out between groups according to the transcystic (TCi) or transcolecocal (TCo) approach, and also evolutionary by periods. The effectiveness of the technique was evaluated using the variable success rate and safety through the analysis of the overall complication rate and the bile leak rate as the most frequent adverse effect. RESULTS: A total of 78 patients were analyzed. The most frequent approach was TCo (62%). The overall success rate was 92%. The TCi group had a shorter operating time, a lower overall complications rate and a shorter hospital stay. The TCo approach was related to a higher rate of clinically relevant bile leak (8%). Complex cases increased significantly during the learning curve without effect on the overall results. CONCLUSIONS: LCBDE+LC is an effective and safe technique during the learning curve. Its results are comparable to those published by more experienced groups and do not present significant differences related to the evolution during learning period.

INTRODUCTION AND AIMS: An anastomotic leak is one of the most dreaded complications in colorectal surgery because it increases postoperative morbidity and mortality. The aim of the present study was to identify whether indocyanine green fluorescence angiography (ICGFA) reduced the anastomotic dehiscence rate in colorectal surgery. MATERIAL AND METHODS: A retrospective study on patients that underwent colorectal surgery with colonic resection or low anterior resection and primary anastomosis, within the time frame of January 2019 and September 2021, was conducted. The patients were divided into the case group, in which ICGFA was performed for the intraoperative evaluation of blood perfusion at the anastomosis site, and the control group, in which ICGFA was not utilized. RESULTS: A total of 168 medical records were reviewed, resulting in 83 cases and 85 controls. Inadequate perfusion that required changing the surgical site of the anastomosis was identified in 4.8% of the case group (nâ¯=â¯4). A trend toward reducing the leak rate with ICGFA was identified (6% [nâ¯=â¯5] in the cases vs 7.1% in the controls [nâ¯=â¯6] [pâ¯=â¯0.999]). The patients that underwent anastomosis site change due to inadequate perfusion had a 0% leak rate. CONCLUSIONS: ICGFA as a method to evaluate intraoperative blood perfusion showed a trend toward reducing the incidence of anastomotic leak in colorectal surgery.
RESUMO
OBJECTIVE: To review the different types of urinary diversion surgeries (UDS) in order to recognize the expected findings in a postoperative study, using different imaging techniques. To recognize the main postoperative complications, both early and late. CONCLUSION: UDS are surgical procedures whose purpose is to redirect urine flow after cystectomy, generally in an oncologic context. The imaging evaluation of urological surgeries is often a radiological challenge, with CT being the most commonly used image modality. Therefore, it is essential to know the main surgical techniques, the expected postoperative findings and the optimization of imaging techniques for early diagnosis and correct evaluation of postoperative complications.

OBJECTIVE: To determine the efficacy of serum procalcitonin (PCT) and C-reactive protein (CRP) in the early diagnosis of anastomotic leak (AL) in patients undergoing colorectal surgery. METHOD: Diagnostic test in a tertiary care hospital. Patients who did not have preoperative measurements of PCT and CRP were excluded. Those with postoperative infection not related to AL were eliminated. The diagnostic efficacy measures were sensitivity (Sn), specificity (Sp), positive (PPV) and negative (NPV) predictive values, positive (LR+) and negative (LR-) likelihood ratios, and area under the receiver operating characteristic curve (AUROC). RESULTS: Thirty-nine patients were analyzed; six had AL (15.4%). PCT and CRP increased on the second postoperative day, only in patients with AL. The cut-off points at the second postoperative day were 1.55 ng/mL for PCT and 11.25 mg/L for CRP. The most efficacious test was PCR at second postoperative day (AUROC: 1.00; Sn: 100%; Sp: 96.7%; PPV: 85.7%; NPV: 100%; LR+: 33.0). CONCLUSIONS: CRP at second postoperative day was the most effective test in the early diagnosis of AL in patients undergoing colorectal surgery, with a cut-off point lower than that reported in the international literature.
OBJETIVO: Determinar la eficacia de la procalcitonina (PCT) y la proteína C reactiva (PCR) séricas en el diagnóstico de fuga anastomótica (FA) en los pacientes sometidos a cirugía colorrectal. MÉTODO: Prueba diagnóstica en un hospital de tercer nivel. Se excluyeron los pacientes que no tuvieron mediciones preoperatorias de PCT y PCR. Se eliminaron los que cursaron con infección posoperatoria no relacionada con FA. Las medidas de eficacia diagnóstica fueron sensibilidad (S), especificidad (E), valores predictivos positivo (VPP) y negativo (VPN), razones de verosimilitud positiva (RV+) y negativa (RV−), y área bajo la curva característica operativa del receptor (AUROC). RESULTADOS: Se analizaron 39 pacientes, de los cuales 6 (15.4%) tuvieron FA. La PCT y la PCR aumentaron al segundo día posoperatorio solo en los pacientes con FA. Los puntos de corte al día 2 fueron 1.55 ng/ml para PCT y 11.25 mg/l para PCR. La prueba más eficaz fue la PCR al día 2 (AUROC: 1.00; S: 100%; E: 96.7%; VPP: 85.7%; VPN: 100%; RV+: 33.0). CONCLUSIONES: La PCR en el segundo día posoperatorio fue la prueba más eficaz en el diagnóstico temprano de FA en los pacientes sometidos a cirugía colorrectal, con un punto de corte inferior a lo reportado en la literatura internacional.

BACKGROUND: Esophagojejunal anastomotic leakage (EJAL) is among the most feared complications after gastric cancer surgery; they entail an uncertain prognosis and relate with increased morbidity and mortality. Factors associated with their development are not well determined, and their diagnosis and treatment vary between institutions. MATERIAL AND METHODS: Retrospective case-control study of patients operated of total gastrectomy with Roux-en-Y esophagojejunostomy from January 2002 to December 2018. We divided our sample into two groups based on the presence of EJAL, and compared demographic, clinical, and histologic variables. We performed a logistic regression model to search risk factors associated with EJAL and described the management offered in our center. RESULTS: We included 58 patients of which 8 (13.7%) presented clinically relevant EJAL. On the comparative analysis, albumin levels and diffuse histology presented a statistically significant difference between groups and presented association with EJAL in the logistic regression model. Regarding treatment of EJAL, ten patients (55.5%) required only conservative measures, whereas eight patients (44.4%) warranted an endoscopic or surgical intervention. CONCLUSION: Our retrospective analysis identified some factors that may be associated with the development of EJAL after gastric cancer surgery. High suspicion and prompt identification of this complication is essential to improve postoperative outcomes in this group.
INTRODUCCIÓN: Las fugas de la anastomosis esófago-yeyunal se encuentran entre las más temidas complicaciones de la cirugía para cáncer gástrico. Estas conllevan un mal pronóstico con una alta mortalidad y morbilidad. Los factores asociados a su desarrollo no están bien determinados y su diagnóstico, y tratamiento varían ampliamente entre instituciones. MATERIAL Y MÉTODOS: Estudio retrospectivo de casos y controles en pacientes operados de gastrectomía total con esófago-yeyuno anastomosis en Y de Roux en el periodo de enero 2002 a diciembre 2018. Nuestra muestra fue dividida en dos grupos con base al desarrollo de fuga de anastomosis en el postoperatorio. Se realizó un análisis comparativo de características demográficas, clínicas y histológicas. Se realizó además una regresión logística para identificar factores de riesgo asociados al desarrollo de fuga de anastomosis en nuestra serie. RESULTADOS: Incluimos a 58 pacientes de los cuales 8 (13.7%) presentaron fuga de anastomosis clínicamente relevante. En el estudio comparativo: Niveles disminuidos de albúmina e histología difusa fueron significativamente mayores en el grupo de fuga y se asociaron en el modelo de regresión logística. En cuanto al tratamiento, diez pacientes (55%) requirieron únicamente tratamiento conservador, mientras que ocho pacientes (44.4%) fueron sometidos a maniobras endoscópicas o quirúrgicas. CONCLUSIÓN: Nuestro análisis retrospectivo identifico factores asociados al desarrollo de fuga de anastomosis posterior a cirugía de cáncer gástrico. Una alta sospecha diagnóstica es esencial para mejorar el pronóstico de estos pacientes.

BACKGROUND: The intestinal anastomotic leakage is the most feared surgical complication of a digestive surgery and is associated with a significant increase of morbidity, mortality and hospital stay. OBJECTIVE: Analyze the risk factors to the intestinal anastomotic leakage in elective surgery. METHOD: Observational and retrospective study in which we include patients with intestinal anastomosis, in elective surgery at the second level hospital from January 2007 to January 2017. RESULTS: 64 patients were included in the study, in which 7 presented anastomotic leakage. The statistically significant risk factors associated with anastomotic leakage were, cocaine use (p = 0.030), neoplasia as a primary pathology (p = 0.008), neoadjuvant treatment for neoplasia (p = 0.003), and end-to-end anastomosis (p = 0.037). Patients with a leakage had a longer hospital stay and a mortality of 14.3%. CONCLUSIONS: The risk factors associated with the presence of anastomotic leakage found in this study are consistent with the reported worldwide literature. However, in our results, it is worth highlighting the use of cocaine as a risk factor, with statistical significance.
ANTECEDENTES: La fuga de una anastomosis intestinal es la complicación quirúrgica más temida de la cirugía digestiva y se asocia con un aumento significativo de la morbimortalidad y de la estancia hospitalaria. OBJETIVO: Analizar los factores de riesgo asociados a la fuga de anastomosis intestinal en cirugía electiva. MÉTODO: Estudio observacional y retrospectivo en el que se recabaron los expedientes de los pacientes operados de anastomosis intestinal en forma electiva en un hospital de segundo nivel de enero de 2007 a enero de 2017. RESULTADOS: Se incluyeron 64 pacientes, de los cuales siete presentaron fuga de la anastomosis. Los factores de riesgo asociados a fuga anastomótica estadísticamente significativos fueron consumo de cocaína (p = 0.030), neoplasia como patología primaria (p = 0.008), tratamiento con neoadyuvantes para neoplasia (p = 0.003) y anastomosis término-terminal (p = 0.037). Los pacientes con fuga tuvieron una estancia intrahospitalaria más prolongada y una mortalidad del 14.3%. CONCLUSIONES: Los factores de riesgo asociados con la presencia de fuga anastomótica encontrados en este estudio son consistentes con los reportados en la literatura mundial. Sin embargo, en nuestros resultados cabe destacar el uso de cocaína como factor de riesgo, con significancia estadística.

INTRODUCTION AND OBJECTIVES: Despite the use of acetazolamide in the management of CSF leak in most patients after CNS surgeries, there is scant evidence in the literature about the efficacy of this established protocol among adult patients in post-spinal surgery observations. We investigated the potential positive effect of acetazolamide in reducing CSF leak after spine surgery. MATERIALS AND METHODS: We conducted a single-center, double-blind, randomized -controlled trial comparing Oral Acetazolamide plus Corrected body (prone) position (CP+A) versus Corrected body (prone) position alone (CP-A) from January 2014 to September 2015 in the Neurosurgery ward of Shariati Teaching Hospital, Tehran University of Medical Sciences, Tehran, Iran. Seventy-two Patients divided into two groups [CP-A group (nâ¯=â¯36, 50%) and CP+A group (nâ¯=â¯36, 50%)] were randomly assigned to this Clinical Trial study. CP+A group (maintained the 3/4 lateral positionâ¯+â¯dose of acetazolamide 20â¯mg/kg/day in 3-4 divided doses for 7 days), and CP-A group (Control group) (maintained the 3/4 lateral position for 7 days with no acetazolamide). RESULTS: Baseline characteristics between the two groups showed no significant differences: Sex (Pâ¯<â¯.637), Age (Pâ¯<â¯.988) and previous CNS operation at other location besides the spine (Pâ¯<â¯.496). Although we reported post-surgical CSF leak in 2/36 (5.55%) of CP+A group and 4/36 (11.11%) of CP-A (control) group, there was no significant difference observed between the two groups (95%CI, 0.081-2.748; ORâ¯=â¯0.471; Pâ¯<â¯.402; Adjusted Pâ¯<â¯.247). Additionally, no significant differences were observed when we examined surgical characteristics, such as the size of the dural opening (Pâ¯<â¯.489) and type of operation (Pâ¯<â¯.465). CONCLUSION: Acetazolamide has no positive effect in controlling CSF leak after dural opening/dural tear in adult patients who undergo spinal surgery, when we considered alongside the one-week prone position. Therefore, acetazolamide administration may not be essential for postoperative spinal surgery for dural tear. Prospective studies involving a larger sample size may be needed to track long-term acetazolamide complications on patients with CSF leak.

INTRODUCTION: Urinary fistula is expected to become more frequent in urological practice as a result of expanding indication of partial nephrectomy given it's oncological results equivalent to those of radical nephrectomy but at a lower risk of progression to chronic kidney disease, lower cardiovascular morbidity, and overall mortality. OBJECTIVES: Review and compare different techniques of contemporary active management for urinary fistula after partial nephrectomy. METHODS: A systematic literature search on the MEDLINE database was conducted in March 2020, combining the terms: "urine leak", "urine leakage", "urinary leak" and "urinary fistula", with: "partial nephrectomy", "nephron sparing surgery" and "renal sparing surgery". This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Only articles related to active treatment were eligible. Abstracts in English and Spanish from the last two decades were screened. No restriction based on study design nor the length of follow-up. PRIMARY OUTCOMES: 1) Leak resolution rate 2) Time course of leak resolution and 3) Number of interventions needed for resolution. RESULTS: Multiple studies were found. There were no randomized controlled trials. Urinary fistula can be solved in many ways with active treatment, with a high success rate (97.5%), an average of 1.4 intervention-per-patients and a mean time for leak resolution of 11 days (median of 3 days). CONCLUSION: There is a high risk of bias due to the study's methodology. There is a broad range of effective alternatives and various approaches to solve urinary fistula in an appropriate timing.

OBJECTIVES: The aim of this study was to evaluate the role of the C-reactive protein (CRP) and white cell count (WC) in the prediction of anastomotic leakage (AL) in major abdominal surgery. METHODS: Multicenter, prospective, and observational study of adult patients who underwent major abdominal surgery. CRP and hemogram were measured after post-operative day (POD) 3 and POD 5. Complications were classified according to the Clavien-Dindo classification. Diagnostic accuracy was evaluated by the area under the receiver operating characteristic curve (AUC). RESULTS: A total of 97 patients were included in the study. The mean age was 63 ± 12 years and 47 (48%) were male. Colorectal (56%) and gastric cancer (36%) were the most frequent diagnoses. About 23% had post-operative complications, of which 5% had AL. The most significant predictive factor was the increase in CRP ≥ 2.84 mg/L among POD 3 and 5 (AUC, 0.99, sensitivity, 95.6%, specificity, 100%, positive likelihood ratio, 23.0). The accuracy of the other biomarkers was lower, CRP on POD 3 (AUC, 0.55), on POD 5 (AUC, 0.93), WC on POD 3 (AUC, 0.33), and POD 5 (AUC, 0.35). CONCLUSION: The increase of CRP among POD 3 and 5 was an early predictor of AL in adult patients with major abdominal surgery.
OBJETIVO: El objetivo de este estudio fue evaluar el papel de la proteína C-reactiva (PCR) y el recuento de glóbulos blancos (RGB) en la predicción de la Fuga Anastomotica (FA) en la cirugía abdominal mayor. MÉTODO: Estudio multicéntrico, prospectivo y observacional de pacientes adultos sometidos a cirugía abdominal mayor. Se midieron la PCR y el hemograma después del día postoperatorio (DPO) 3 y DPO 5. Las complicaciones se categorizaron según la clasificación de Clavien-Dindo y la precisión diagnóstica se evaluó mediante el área bajo la curva (AUC). RESULTADOS: Se incluyeron un total de 97 pacientes. La edad media era de 63 ± 12 años y 47 (48%) eran hombres. El factor predictivo más significativo fue el aumento de la PCR ≥ 2,84 mg/L entre los DPO 3 y 5 (AUC, 0,99, sensibilidad, 95,6%, especificidad, 100%, ratio de probabilidad positiva, 23,0). La precisión de los demás biomarcadores fue menor, la PCR en el DPO 3 (AUC, 0,55), en el DPO5 (AUC, 0,93), el RGB en el DPO 3 (AUC, 0,33) y en el DPO 5 (AUC, 0,35). CONCLUSIONES: El aumento de la PCR entre los DPO 3 y 5 fue un predictor temprano de FA en pacientes adultos con cirugía abdominal mayor.

OBJETIVO: Identificar los factores asociados a dehiscencia de anastomosis de intestino delgado y grueso. MÉTODO: Se incluyeron 92 anastomosis de intestino delgado y grueso, en mayores de 18 años, realizadas en 2012-2016. Se evaluaron factores asociados en el preoperatorio, el transoperatorio y el posoperatorio. RESULTADOS: Se presentó dehiscencia de anastomosis en el 13% de los casos. Se encontró una asociación significativa con ingesta previa de medicamentos (p = 0.05; odds ratio [OR]: 1.17; IC 95%) y con anastomosis primaria (p = 0.05; OR: 3.6; 0.92-14.5). En los pacientes con dehiscencia se incrementó la estancia intrahospitalaria. CONCLUSIÓN: La presencia de dehiscencia de anastomosis fue similar a lo reportado en la literatura. Los factores asociados fueron la ingesta previa de medicamentos y la anastomosis primaria. OBJECTIVE: To identify the factors associated with dehiscence of anastomosis of the small and large intestine. METHOD: 92 anastomoses of the small and large intestine were included in patients over 18 years of age, performed in 2012-2016. Associated factors were evaluated in pre, trans and postoperative. RESULTS: Anastomosis dehiscence was presented in 13%. A significant association was found for previous medication intake (p = 0.05; odds ratio [OR]: 1.17; 1.024-1.33) and primary anastomosis (p = 0.05, OR: 3.6; 0.92-14.5). In patients with dehiscence, the hospital stay was increased. CONCLUSION: The presence of dehiscence of anastomosis was similar to that reported in the literature. The associated factors were previous medication intake, and primary anastomosis.

INTRODUCTION AND AIM: Total gastrectomy is utilized in different pathologies. Esophagojejunostomy leakage is a frequent complication. Our aim was to determine the association of the neutrophil-lymphocyte ratio (NLR) with esophagojejunostomy leakage that subsequently required invasive treatment. MATERIALS AND METHODS: A retrospective study included patients that underwent esophagojejunostomy within the time frame of 2002-2017. Patients were grouped into those with or without anastomotic leakage that had conservative treatment (group A) and those with anastomotic leakage that had invasive treatment (group B). ROC curves and the Youden index were used for the optimum cutoff values of the NLR. RESULTS: Fifty-seven patients were included. Thirty-two (56.14%) were men, and mean patient age was 61.8 ± 13.4 years. Forty-five patients were assigned to group A and 12 to group B. Mean NLR was higher for group B on postoperative day 3 (group A 9.5 ± 7.5 vs. group B 13.9 ± 4.9) (p = 0.05). Mean total leukocytes was higher in group B on postoperative day 5 (group A 7.8 ± 3.4 × 103/mcl vs. group B 10.3 ± 4.4 × 103/mcl) (p = 0.03). NLR and total leukocyte accuracy on postoperative day 3 was calculated with ROC curves, at 0.78 and 0.63, respectively. For the NLR and leukocyte count, sensitivity was 91.7% and 58%, specificity was 64.4% and 60%, positive predictive value was 40% and 28%, and negative predictive value was 96% and 84%, respectively. CONCLUSIONS: Postoperatively, the NLR identified the total gastrectomy with esophagojejunostomy patients that subsequently required an invasive procedure secondary to esophagojejunostomy leakage.

There are different surgical techniques for reconstruction of the urinary tract in kidney transplant. However, urinary complications are frequent in the postoperative period, being the ureter the frequent location of these complications. This results in high health care costs, increasing patient morbimortality and sometimes graft loss. For this reason, prevention, correct diagnosis and treatment are important. The aim of this review is to describe the surgical techniques most commonly used in kidney transplant for ureteroneocystostomy. To analyze the advantages and disadvantages of each of them and to compare their complications. On the other hand, we summarize the recent literature on the four most frequent urinary complications in the postoperative period after transplantation. The possible causes and treatment of urine leak, ureteri cobstruction, hematuria and vesicoureteral reflux are presented.
Existen diferentes técnicas quirúrgicas para la reconstrucción del tracto urinario en el trasplante renal. Sin embargo es frecuente la aparición de complicaciones urinarias en el postoperatorio, siendo el uréterla localización frecuente de las mismas. Esto implica un alto gasto sanitario, aumentando la morbimortalidad del paciente y pudiendo llegar a desencadenar la pérdida del injerto. Por ello es importante la prevención, el correcto diagnóstico y su tratamiento. El objetivo de esta revisión es describir las técnicas quirúrgicas más usadas en el trasplante renal para la ureteroneocistostomía. Analizar las ventajas y desventajas de cada una de ellas y comparar sus complicaciones. Por otro lado se resume la literatura reciente sobre las cuatro complicaciones urinarias más frecuentes en el postoperatorio del trasplante. Se exponen las posibles causas y tratamiento de la fuga urinaria, la obstrucción ureteral, la hematuria y el reflujo ureterovesical.

BACKGROUND: Anastomotic leak is a serious complication of rectal cancer surgery that leads to increased morbidity and mortality. Its incidence is 3-21%, usually appearing 5-7 days after surgery, although there are cases of late presentation as chronic anastomotic fistulas or sinuses. CASE REPORT: We present three cases of patients who underwent anterior resection for rectal cancer and developed necrotizing fasciitis due to late anastomotic leaks. CONCLUSIONS: We believe that early and resolutive surgical treatment is recommended for chronic anastomotic fistulas or sinuses, even when asymptomatic, because of the associated risk of necrotizing fasciitis.
ANTECEDENTES: La dehiscencia anastomótica es una complicación grave de la cirugía del cáncer de recto que conlleva un aumento de la morbimortalidad. Su incidencia se sitúa en un 3-21%, manifestándose habitualmente alrededor del quinto a séptimo días de posoperatorio, si bien existen casos de presentación tardía en forma de fístulas o sinus anastomóticos crónicos. CASOS CLÍNICOS: Presentamos tres casos de pacientes intervenidos mediante resección anterior por cáncer de recto que desarrollaron fascitis necrotizante secundaria a dehiscencia anastomótica tardía. CONCLUSIONES: Creemos recomendable el tratamiento quirúrgico resolutivo y precoz de las fístulas y sinus anastomóticos crónicos, incluso asintomáticos, por el potencial riesgo de fascitis necrotizante que suponen.
