Stent Management of Leaks After Bariatric Surgery: a Systematic Review and Meta-analysis.

BACKGROUND: Despite the low rates of complications of bariatric surgery, gastrointestinal leaks are major adverse events that increase post-operative morbidity and mortality. Endoscopic treatment using self-expanding stents has been used in the therapeutic management of these complications with preliminary good results. METHODS: We performed a systematic review and meta-analysis of self-expanding stents placement for the management of gastrointestinal leaks after obesity surgery. Overall proportion of successful leak closure, stent migration, and reoperation were analysed as primary outcomes. Secondary outcomes were patients' clinical characteristics, duration and type of stent, other stent complications, and mortality. RESULTS: A meta-analysis of studies reporting stents was performed, including 488 patients. The overall proportion of successful leak closure was 85.89% (95% CI, 82.52-89.25%), median interval between stent placement and its removal of 44 days. Stent migration was noted in 18.65% (95% CI, 14.32-22.98%) and the overall proportion of re-operation was in 13.54% (95% CI, 9.94-17.14%). The agreement between reviewers for the collected data gave a Cohen's κ value of 1.0. No deaths were caused directly by complications with the stent placement. CONCLUSIONS: Endoscopic placement of self-expanding stents can be used, in selected patients, for the management of leaks after bariatric surgery with a high rate of effectiveness and low mortality rates. Nevertheless, reducing stent migration and re-operation rates represents an important challenge for future studies.

Análisis del impacto de la cirugía bariátrica en el gasto farmacológico a medio plazo / Analysis of the impact of bariatric surgery on medium-term pharmacological expenditure

Introducción: La obesidad y las enfermedades asociadas a ella suponen un importante problema, y no solo sanitario, sino también económico, ya que muchas de esas patologías son subsidiarias de tratamiento farmacológico de por vida. La cirugía bariátrica y metabólica, a priori, disminuye la demanda de medicamentos de estos pacientes, pero puede condicionar otro tipo de necesidades farmacológicas. El objetivo del estudio es demostrar si existe un descenso real del gasto farmacológico tras la cirugía bariátrica. Material y métodos: Análisis retrospectivo transversal de los pacientes intervenidos en nuestro centro entre 2012 y 2016, comparando las distintas comorbilidades y los gastos farmacológicos asociados a ellas un mes antes y a los 2años de la cirugía. Resultados: Fueron intervenidos 400 pacientes. Se presentaron los resultados mostrando para cada una de las técnicas quirúrgicas estudiadas las diferencias entre la resolución de las distintas comorbilidades y el ahorro farmacológico generado. La comorbilidad más coste-efectiva del estudio fue la diabetes mellitus tipo2 (DM2). La técnica quirúrgica con mejores resultados fue el bypass metabólico, presentando una diferencia de costes tras la cirugía de 507euros mensuales (p<0,001). Conclusiones: En un seguimiento de 2años tras la cirugía bariátrica se produce un descenso en la prevalencia de las enfermedades asociadas a la obesidad y del gasto farmacológico asociado a ellas, lo que demuestra que este tipo de intervención resulta eficiente a medio plazo.

Introduction: Obesity and associated diseases represent an important health and economic problem since pharmacological treatment for many of these pathologies needs lifelong subsidies. Theoretically, bariatric and metabolic surgery decreases the medication requirements of patients for these diseases but may result in other types of pharmacological needs. This study aims to demonstrate whether there is a real decrease in pharmacological expenditure after bariatric surgery. Material and methods: Retrospective cross-sectional analysis of patients who were treated in our centre between 2012 and 2016, comparing different associated comorbidities and pharmacological expenses one month before and 2years after surgery. Results: 400 patients were operated. The results were presented, showing the differences between the resolution of the different comorbidities and the pharmacological savings generated for each of the surgical techniques studied. The most cost-effective comorbidity in the study was type2 diabetes mellitus (DM2). The surgical technique with the best results was metabolic bypass, presenting a cost difference after surgery of 507euros per month (P<.001). Conclusions: In a 2-year follow-up after bariatric surgery, a decreased prevalence of obesity-related diseases and associated pharmacological expenditure was observed, showing the efficiency of this intervention over the medium term.

Analysis of the 'Evaluation Indicators' of an Enhanced Recovery After Bariatric Surgery Pathway in the First Six Months After Implementation.

The implementation of a clinical pathway in bariatric surgery (BS) might facilitate systemic care. Focusing on enhanced recovery after surgery (ERAS) programs may also improve surgical outcomes depending on the degree of adherence achieved. We hypothesized that the implementation of an ERAS clinical pathway in BS (ERABS) improves clinical outcomes compared to traditional treatment in a tertiary care hospital. The main objective was to assess the degree of adherence to the ERABS program. Secondary objectives were to evaluate compliance with the quality indicators of the Spanish Society for Obesity Surgery (SECO) and overall patients' satisfaction. A retrospective observational study was designed. Data from patients who underwent BS into an ERABS context were reviewed and compared with traditionally treated patients. Process and outcomes indicators adapted from RICA (Recuperación Intensificada en Cirugía Abdominal) pathway, degree of compliance with SECO quality indicators and patients' satisfaction were analyzed. Forty-three patients were included per group. Indicators' compliance rate per patient was 83.23%. Differences were found in postoperative bleeding, immediate morbidity and overall morbidity, but not in severity of complications. No patient felt dissatisfied or unsatisfied. Average compliance with indicators of process and outcome was 90.45%. Overall morbidity in ERABS group did not differ from that recommended by SECO, but traditional group did show significant increase. Adherence was 83.63% and overall incidence of complications was 7%. Our study shows improved clinical outcomes in ERABS group with a high degree of adherence. Quality indicators were met, improving overall morbidity with no difference in the severity of complications.

Bull horn injuries. A 40-year retrospective study with 572 patients.

BACKGROUND: Although bullfighting festivals were traditionally attributed to the cultural idiosyncrasies of the Ibero-American people, they also exist world-wide. METHODS: A retrospective study was conducted, reviewing the medical records of patients treated on our service for bull horn injuries between January 1978 and December 2019. RESULTS: There were 572 admissions due to bull horn injuries. 54 of these patients had multiple injuries. The average annual admission was 13.6 patients. The most frequent injuries were located in the lower extremities, perineum, and abdomen. Forty-seven laparotomies were performed, revealing intra-abdominal visceral impairment on 39 occasions. The most frequently injured organs were the intestine and liver. The most frequent complications were skin devitalisation, infection and post-operative eventration. The recorded mortality was 0.87%. CONCLUSION: We wish to highlight the importance of injuries caused by bull horns worldwide. These are high-impact injuries with specific intrinsic characteristics that require regulated medical and surgical care.

Síndrome de la mama fantasma posmastectomía. Estudio de prevalencia y características clínicas en un hospital de tercer nivel / Post-mastectomy phantom breast syndrome. Study of prevalence and clinical characteristics in a tertiary hospital

Objetivo: Conocer la prevalencia y características del síndrome de la mama fantasma en nuestro entorno. Pacientes y métodos: Se realizó una encuesta telefónica a 50 mujeres mastectomizadas entre los años 2002 y 2009 en el Hospital General Universitario de Castellón. Se preguntó sobre la presencia de dolor antes del diagnóstico de la enfermedad y de la cirugía, del síndrome de dolor posmastectomía y del síndrome de la mama fantasma, ampliando el interrogatorio en caso de respuesta afirmativa para conocer las características de la sintomatología, el momento de aparición, la frecuencia de aparición, la duración de la clínica y la necesidad o no de tratamiento farmacológico específico en cada síndrome. Se realizó un análisis descriptivo de los datos obtenidos. Resultados: El 76% de las mujeres interrogadas presentaron algún tipo de sensación extraña o dolorosa en la zona de la cicatriz mamaria, de las cuales el 65,8% presentó sensaciones no dolorosas y el 34,2% dolorosas. El síndrome de la mama fantasma apareció en el 38% de las mujeres interrogadas, y en muchos de los casos (31,6%) de las que respondieron afirmativamente se expresaba en forma de picor en el pezón ausente. Conclusiones: El síndrome de dolor posmastectomía y el síndrome de la mama fantasma son entidades poco conocidas, aunque prevalentes en nuestro medio. Tienen un carácter complejo y multifactorial, por lo que es importante conocerlas para conseguir un correcto tratamiento de las pacientes afectas, y así mejorar su calidad de vida

Objective: To determine the prevalence of post-mastectomy pain syndrome and phantom breast syndrome in our environment. Patients and methods: We performed a telephone survey of 50 women who underwent mastectomy between 2002 and 2009 in the General Hospital of Castellon (Spain). The women were asked about the presence of pain before diagnosis of the disease and surgery, post-mastectomy pain syndrome, and phantom breast syndrome. Women with symptoms were asked about their characteristics, time of onset, frequency, duration, and whether or not a specific pharmacological treatment was needed for each syndrome. A descriptive analysis was performed of the data obtained. Results: A total of 76% of the women surveyed had some kind of strange or painful sensation in the breast scar, 65.8% of whom had painless sensations and 34.2% had painful sensations. Phantom breast syndrome appeared in 38% of the surveyed women and manifested as an itch in the absent nipple in 31.6% of the women. Conclusions: Post-mastectomy pain syndrome and phantom breast syndrome are little known entities, although they prevalent in our environment. These syndromes are complex and multifactorial; therefore, familiarity with their characteristics is essential to provide affected women with proper treatment and improve their quality of life

Rendimiento diagnóstico de la punción aspiración con aguja fina de tejido tiroideo / Diagnostic efficacy of fine needle aspiration of thyroid tissue

Introducción. La punción aspiración con aguja fina (PAAF) de la glándula tiroides constituye un proceso diagnóstico que permite determinar de forma segura y fiable, si un nódulo tiroideo es benigno o maligno. Objetivo. El objetivo del estudio fue evaluar la eficacia diagnóstica de la PAAF en nuestro centro. Material y métodos. Se llevó a cabo de 2009 a 2013 un estudio retrospectivo de pacientes con nódulo tiroideo sospechoso de ser maligno. Las variables del estudio fueron: edad, sexo, tamaño del nódulo tiroideo, realización de PAAF, estudio anatomo-patológico de la biopsia y diagnóstico definitivo. Se comparó el rendimiento diagnóstico de la PAAF frente a los resultados de la biopsia posoperatoria. Resultados. Durante los cinco años del estudio, se practicó PAAF de tejido tiroideo a 112 pacientes (30,2 %, hombres, y 69,8 %, mujeres), con un tamaño medio nodular de 2 cm (rango: 1 a 4). La PAAF fue positiva para neoplasia maligna en 26 casos (23,2 %) y negativa en 86 casos (76,8 %). Los resultados del rendimiento de la prueba fueron: sensibilidad de 45,5 % (intervalo de confianza 95 % [IC95%] 28,1-63,6), especificidad de 86,1 % (IC95% 76,5-92,8), valor predictivo positivo de 57,7 % (IC95% 36,9-76,6) y valor predictivo negativo de 79,1 % (IC95% 69-87,1). Conclusión. Tras este análisis, se obtiene un resultado malo con posibilidad de ser mediocre, por lo que habría que replantearse la utilidad de esta prueba invasiva en nuestro centro y la búsqueda de posibles errores.

Background: Thyroid fine needle aspiration (FNA) is a safe and reliable diagnostic procedure for determining if a thyroid nodule is benign or malignant. Objective: The objective of this study was to evaluate the efficacy of FNA diagnosed in our center. Material and methods: Retrospective study of patients with thyroid nodule suspicious for malignancy, in the period 2009 to 2013. The variables used in this study were: age, sex, size of thyroid nodule, FNA performance, pathology and definitive diagnosis. The diagnostic accuracy of FNA was compared with the results of postoperative biopsy. Results: During the 5-year study, FNA of thyroid tissue was performed at 112 patients (30.2% men and 69.8% women), with nodules of average size of 2 cm (range 1-4). FNA was positive for malignancy in 26 cases (23.2%) and negative in 86 cases (76.8%). The performance results of the test were: sensitivity 45.5% (confidence interval [CI] 95%: 28.1% -63.6%), specificity of 86.1% (95% CI: 76.5 % - 92.8%), positive predictive value of 57.7% (95% CI: 36.9% - 76.6%) and negative predictive value of 79.1% (95% CI: 69% - 87 1%) Conclusion: A bad result with the possibility of being mediocre is obtained with this analysis, which should rethink the usefulness of this invasive test in our center and search for possible errors.
