High rate of de novo esophagitis 5 years after sleeve gastrectomy: a prospective multicenter study in Spain.

BACKGROUND: Major concerns years after the sleeve gastrectomy (SG) include weight regain, development of hiatal hernia (HH) and gastroesophageal reflux disease, with esophagitis and Barrett's esophagus (BE). Both problems could be related, and the incidence of asymptomatic patients is troubling. OBJECTIVE: To study the incidence of reflux symptoms, esophagitis, BE, HH, and asymptomatic pathology and their relationship with weight regain in patients 5 years after undergoing SG at different bariatric centers in Spain. SETTING: Public and private hospitals with bariatric surgery units. METHODS: Prospective, multicenter, nonrandomized study involving 13 Spanish hospitals with a cumulative experience of 4,500 patients having undergone the SG procedure and patients who had been subjected to the procedure at least 5 years previously along with preoperative gastroscopy. The clinical history, preoperative gastroscopy, and technical details of the SG were recorded. A specific clinical questionnaire was given that recorded the intake volume, perception of satiety, and gastroesophageal reflux (GER) symptoms. Gastroscopy, pH-metry, and manometry studies were carried out, and the data were analyzed statistically. The study has been authorized by the official Spanish ethics committee CEI/CEIm Hospital Universitario Gran Canaria Dr Negrín (code 2019-216-1). RESULTS: One hundred and five patients who underwent SG and who had with at least 5 years of follow-up were included. All procedures were performed laparoscopically. The mean age of patients was 51.1 years, and 70.5% were women. The mean characteristics of the SG procedure were a 37.2F probe, at 4.6 cm from the pylorus, and a crura closure was performed in 5 cases. There were no major complications (Clavien-Dindo grade >3) or deaths. The average preoperative body mass index was 46.3 kg/m2, the minimum reached was 20.6 kg/m2, whereas the average after 5 years was of 34.5 kg/m2. GER, HH, and esophagitis symptoms went from 17.1%, 28.6%, and 5.7%, respectively, before the SG to 76%, 30.5%, and 31.4%, respectively, 5 years after the procedure. Symptoms persisted over the years in 37.1% of cases and presented de novo in 52.8% of cases. Fifty-three percent of manometries (n = 27, total 51) and 64% of pH-metries (n = 32, total 53; DeMeester average score was 65) were pathologic 5 years after the procedure. Concerning gastroscopies, 5 years after the procedure, HH was found in 33 patients (30.5% of total) and esophagitis in 32 patients (31.4% of total). Eighty patients (76%) had GER symptoms, and 25 patients (24%) were asymptomatic. Only 1 patient (.9%) developed BE. CONCLUSIONS: Our study has confirmed a high rate of both persistent and de novo esophagitis and hiatal hernia, many of which were asymptomatic, 5 years after SG had been performed. Weight regain and a striking increase in gastric capacity are risk factors indicative of esophagitis, even when patients are asymptomatic. We consider a control gastroscopy and the preventive use of proton pump inhibitors necessary in these cases regardless of symptoms. We recommend that a control gastroscopy should be performed in all cases regardless of symptoms 5 years after SG. Further studies are needed to validate these recommendations.

Niveles de proteína C reactiva, bilirrubina y leucocitos como predictores de evolución anatomopatológica apendicular / Levels of C-reactive Protein, Bilirubin and Leucocytes as Predictors of Anotomopathological Appendicular Evolution

RESUMEN Introducción: La apendicitis aguda es la urgencia quirúrgica más frecuente en cualquier hospital del mundo. Aunque la mayoría de las veces se trata de un proceso intrabdominal banal, en ocasiones presenta una no desdeñable morbilidad y todavía en la época actual. Esta morbimortalidad se asocia, en la mayoría de los casos, a estados avanzados de afección apendicular. Objetivo: Predecir, con la cifra de bilirrubina, la proteína C reactiva y el recuento leucocitario, el estado del proceso apendicular agudo que presentaban los pacientes. Métodos: Se realizó un estudio observacional descriptivo en el que se han incluido aquellos pacientes intervenidos por sospecha de apendicitis aguda durante un periodo de 3 años (2017-2019) que cumplían los criterios de inclusión. Se analizó, como datos de laboratorio, la cifra de leucocitos, proteína C reactiva y bilirrubina. Resultados: Se observó un aumento de las cifras de proteína C reactiva y bilirrubina en los casos apendiculares avanzados, al igual que otros autores han evidenciado en la literatura. Así mismo, estos dos valores han resultado ser un factor de riesgo para presentar formas graves. El nivel de leucocitos sin embargo no ha demostrado relacionarse con la gravedad del proceso. Conclusiones: Vemos relevante el uso de los biomarcadores estudiados para predecir la gravedad apendicular con el objetivo de mejorar la asistencia en estos enfermos y disminuir las complicaciones derivadas del retraso terapéutico(AU)

ABSTRACT Introduction: Acute appendicitis is the most frequent surgical emergency in any hospital worldwide. Although most of the time it is a trivial intraabdominal process, sometimes it presents an unneglectable morbidity. This morbidity and the subsequent mortality are associated, in most cases, with advanced stages of an appendicular disease. Objective: To predict, using the value corresponding to bilirubin, C-reactive protein and leukocyte count, the state of acute appendicular process presented by patients. Methods: A descriptive observational study was carried out, including patients operated on for suspected acute appendicitis during a period of three years (2017-2019) and who met the inclusion criteria. The values for leukocyte count, C-reactive protein, and bilirubin were analyzed as laboratory data. Results: An increase in the values of C-reactive protein and bilirubin levels was observed in advanced appendicular cases, as other authors have shown in the medical literature. Likewise, these two values ​​have turned out to be a risk factor for presenting severe forms. However, the level of leukocytes has not been shown to be related to the severity of the process. Conclusions: We consider the use of the biomarkers studied as relevant to predict appendicular severity in view of improving care of these patients and reducing complications derived from therapeutic delay(AU)
