Introducción: La obesidad y el índice de masa corporal (IMC) actúan como factores de riesgo para diversas neoplasias, sin una clara relación con el cáncer gástrico no cardial. La cirugía bariátrica es el manejo más efectivo contra la obesidad. La incidencia de cáncer gástrico posterior a la gastrectomía vertical es aún incierta. El primer caso de cáncer gástrico, 4 años posterior a una gastrectomía vertical, se publicó en 2014, y hasta la fecha se han descrito 11 casos en la literatura. Caso Clínico: Masculino de 52 años, con antecedente de gastrectomía vertical, presenta cuadro clínico, endoscópico e histopatológico compatible con adenocarcinoma de cuerpo gástrico 5 años posterior a cirugía bariátrica. Recibe tratamiento neoadyuvante con quimioterapia esquema FLOT 6 ciclos, luego gastrectomía total oncológica laparoscópica con disección ganglionar D2 y adyuvancia con esquema FOLFOX 6 ciclos. Estudio histopatológico resulta adenocarcinoma pobremente diferenciado con 90% de regresión tumoral, sin metástasis ganglionar en lo extraído (pT1bN0M0). Seguimiento por 6 meses sin signos clínicos e imagenológicos de recidiva tumoral. Discusión: Existiría una relación directa entre el IMC y cáncer de unión gastroesofágica, la que no ha sido demostrada para cáncer gástrico no cardial. El estudio con endoscopía digestiva alta previo a cirugía bariátrica no está estandarizado, sin embargo, es recomendable realizarlo. La cirugía bariátrica podría disminuir el riesgo de ciertas neoplasias, mientras que la incidencia de cáncer gástrico posterior a dicha cirugía aún no está bien definida. Es recomendable realizar seguimiento endoscópico a los pacientes posoperados de gastrectomía vertical, más aún en sintomáticos.
Introduction: Obesity and body mass index (BMI) are risk factors for different types of cancer, yet there is no clear association to non-cardia gastric cancer. Bariatric surgery is the most effective treatment for obesity. Incidence of gastric cancer after bariatric surgery remains unclear. The first case report of gastric cancer 4 years following a vertical sleeve gastrectomy was reported in 2014 and up until now, only 11 cases have been reported. Case report: 52-year-old man, who had undergone a sleeve gastrectomy 5 years ago, presented clinical, endoscopic, and histological features, compatible with a gastric body adenocarcinoma. He received neoadjuvant chemotherapy of 6 cycles of FLOT, an oncological laparoscopic total gastrectomy with D2 lymph node dissection and adjuvant chemotherapy with 6 cycles of FOLFOX. Biopsy reported a poorly differentiated adenocarcinoma with a 90% of tumor regression, with no signs of ganglion metastases (pT1bN0M0). 6-month follow-up showed no clinical or imaging signs of relapse. Discussion: There is a direct association between higher BMI and gastroesophageal junction cancer, but no clear evidence of this association with non-cardia gastric cancer. The preoperative evaluation with an upper endoscopy before bariatric surgery is not standardized, yet it is possible to recommend it. Bariatric surgery could lower the risk of certain cancers, yet the incidence of gastric cancer after this procedure is not yet defined. Endoscopic follow-up is recommended to all postoperative patients, especially if they become symptomatic.

La fístula gástrica aguda es una de las principales complicaciones vinculadas a la gastrectomía vertical laparoscópica (GVL). Existen múltiples opciones terapéuticas para su resolución, siendo el tratamiento endoscópico mediante colocación de clips o stents uno de los más importantes. La aplicabilidad de cada método va a depender del tipo de fístula y del estado del paciente. Presentamos el caso de una mujer de 35 años, que desarrolla una fístula aguda posterior a una GVL. Se realiza tratamiento endoscópico con colocaciónn del sistema "over-the-scope clip" (Ovesco®) a nivel del orificio fistuloso, con posterior colocaciónn de stent metálico auto expandible.
Acute gastric fistula is one of the main complications associated with laparoscopic vertical gastrectomy (LVG). There are multiple therapeutic options for its resolution, being endoscopic treatment by placing clips or stents one of the most important. The applicability of each method will depend on the type of fistula and the patient's condition. We present the case of a 35-year-old woman who developed an acute fistula after LGV. Endoscopic treatment is performed with placement of the over-the-scope clip system (Ovesco®) at the level of the fistulous orifice, with subsequent placement of a self-expanding metal stent.

Resumen México es el primer lugar a nivel mundial en obesidad; la Diabetes tipo 2 se encuentra asociada hasta en 90%. Este estudio observacional ambispectivo del 2009 al 2015, compara las tasas de remisión de diabetes tipo 2 en pacientes con IMC >35 kg/m2 operados de Bypass Gástrico Laparoscópico (BPGL) vs Gastrectomía Vertical en Manga Laparoscópica (GVML) monitorizando la normalización de los niveles de glucosa plasmática, disminución del porecentaje de HbA1C y cese en el uso de antidiabéticos por lo menos un año, siendo ese su objtetivo. Se analizaron los expedientes clínicos de los pacientes operados de BPGL y GVML con obesidad mórbida y diabetes tipo 2 en el periodo de enero del 2009 a junio del 2015, registrando en una base de datos las variables medibles de cada paciente. Se utilizó una tabla de ANOVA y la prueba t de Student mediante programa de análisis de datos SPSS®. Posterior a la cirugía se registraron cifras de glucosa en ayuno <100 mg/dl desde los primeros tres meses en la mayoría de los pacientes. Después de 12 meses de seguimiento los niveles de glucosa descendieron de 152.16 ± 65.3 mg/dl a 88.16 ± 14.05 mg/dl (p< 0.001), el porcentaje de HbA1C bajó de 7.4 ± 1.4 a 5.3 ± 0.8 (p <0.001), cuatro pacientes continuaron con algún tipo de medicamento, dos con insulina y dos con hipoglucemiantes orales. Existió una remisión de la diabetes tipo 2 en 20 pacientes (80%). En los pacientes con obesidad mórbida y diabetes tipo 2 tratados en el Hospital Central Militar, la GVML y el BPGL han demostrado seguridad y efectividad en la remisión de diabetes tipo 2 a mediano plazo. Sin diferencia significativa entre ambos.

Resumen Objetivo: Comparar los resultados obtenidos en calidad de vida, pérdida ponderal y resolución de comorbilidades al año, en pacientes con obesidad mórbida intervenidos de Gastrectomía vertical laparoscópica (GVL) o bypass gástrico en Y de Roux laparoscópico (BGYRL) en nuestro centro. Materiales y Método: Estudio observacional de una base de datos prospectiva. Las variables del estudio fueron IMC pre y posoperatorio, porcentaje de exceso de IMC perdido (PEIMCP), puntuación obtenida en los cuestionarios Gastrointestinal Quality of Life Index (GIQLI) y Bariatric Analysis and Reporting Outcomes System (BAROS) y la resolución de las comorbilidades. Resultados: De 60 pacientes: 37 fueron intervenidos de GVL y 23 de BGYRL. El IMC posoperatorio al año fue 29,9 ± 4 kg/m2 en BGYRL y 31,3 ± 5 kg/m2 en GVL. El PEIMCP fue de 74,5 ± 19,2% (BGYRL) y de 67,5 ± 23,1% (GVL). Con BAROS, se obtuvieron resultados buenos o superiores en el 87% (BGYRL) y en 83,8% (GVL). Con GIQLI se obtuvo una puntuación media de 108,3 ± 19 (BGYRL) y 109,8 ± 18,3 (GVL). No se observaron diferencias estadísticamente significativas entre ambos grupos en ninguna de las variables previas. En cuanto a la evolución de las comorbilidades, 50% de BGYRL y 53,8% de GVL presentaron resolución de todas las comorbilidades. Conclusiones: Ambas técnicas son eficaces en cuanto al PEIMCP, a la calidad de vida y al control de comorbilidades al año de la intervención. El BGYRL presenta mejores resultados en PEIMCP y BAROS, y la GVL presenta mejor puntación global y especifica de síntomas digestivos con GIQLI, sin ser diferencias estadísticamente significativas.
Aim: The purpose of our study was to compare the postoperative quality of life, weight loss and improvement of co-morbidities in laparoscopic Roux-en-Y gastric bypass (LRYGB) and Laparoscopic sleeve gastrectomy (LSG) patients one year after surgery. Materials and Method: Match pair analysis of the prospectively collected database of the 23 gastric bypass and 37 gastric sleeve patients operated on in our hospital was performed. Weight loss, quality of life and improvement of co-morbidities were measured at one year after surgery. The quality of life parameters were measured with two standard questionnaires: Gastrointestinal Quality of Life Index (GIQLI) and Bariatric Analysis and Reporting Outcomes System (BAROS). Results: After one year of follow-up the mean BMI was 29.9 ± 4 kg/m2 in LRYGB and 31.3 ± 5 kg/m2 in LSG. The percent excess BMI Loss (%EBMIL) was 74.5 ± 19.2% (LRYGB) and 67.5 ± 23.1% (LSG). A success score in BAROS was obtained in 87% (LRYGB) and 83.8% (LSG). The mean GIQLI score was 108.3 ± 19 (LRYGB) and 109.8 ± 18.3 (LSG). These results did not differ significantly. Remission of co-morbidities was similar in the BGYRL and LSG groups (50 vs 53.8%). Conclusions: Both types of surgery are effective in quality of life, co-morbidities and weight loss after one year of follow-up. The LRYGB produced better results in %EBMIL and BAROS, and the LSG produced better results in GIQLI (overall and digestive symptoms). These results did not differ significantly.

ABSTRACT Introduction: to evaluate urinary biochemical alterations related to urolithogenesis processes after sleeve gastrectomy (SG). Materials and methods : prospective study with 32 individuals without previous diagnosis of urolithiasis who underwent SG. A 24-h urine test was collected seven days prior to surgery and at 6-month follow-up. The studied variables were urine volume, urinary pH, oxalate, calcium, citrate, and magnesium and calcium oxalate super saturation (CaOx SS). Results: patients were mainly women (81.2%), with mean age of 40.6 years. Mean pre- and postoperative BMI were 47.1 ± 8.3 Kg/m2 and 35.5 ± 6.1 Kg/m2, respectively (p<0.001). Urine volume was significantly lower at the postoperative evaluation in absolute values (2,242.50 ± 798.26 mL x 1,240.94 ± 352.39 mL, p<0.001) and adjusted to body weight (18.58 ± 6.92 mL/kg x 13.92 ± 4.65 mL/kg, p<0.001). CaOx SS increased significantly after SG (0.11 ± 0.10 x 0.24 ± 0.18, p<0.001). Moreover, uric acid levels were significantly lower at the postoperative evaluation (482.34 ± 195.80 mg x 434.75 ± 158.38 mg, p=0.027). Urinary pH, oxalate, calcium, citrate, and magnesium did not present significant variations between the pre- and postoperative periods. Conclusion: SG may lead to important alterations in the urinary profile. However, it occurs in a much milder way than that of RYGB.
RESUMO Introdução: avaliar as alterações bioquímicas urinárias relacionadas aos processos de litíase urinária após gastrectomia vertical (GV). Método: estudo prospectivo, com 32 indivíduos submetidos a GV, sem diagnóstico prévio de urolitíase. Foi coletada urina de 24 horas, sete dias antes da operação e no retorno de 6 meses. As variáveis estudadas foram volume de urina, pH urinário, oxalato, cálcio, citrato e super saturação de oxalato e cálcio (SS CaOx). Resultados: os pacientes foram em sua maioria mulheres (81,2%), com idade média de 40,6 anos. O IMC médio pré e pós-operatório foi 47,1 ± 8,3 Kg/m2 e 35,5 ± 6,1 Kg/m2, respectivamente (p<0,001). O volume de urina foi significativamente baixo na avaliação pós-operatória em valores absolutos (2.242,50 ± 798,26 mL versus 1.240,94 ± 352,39 mL, p<0,001) e ajustado ao peso corporal (18,58 ± 6,92 mL/kg versus 13,92 ± 4,65 mL/kg, p<0,001). A SS CaOx aumentou significativamente após a GV (0,11 ± 0,10 versus 0,24 ± 0,18, p<0,001). Além disso, os níveis de ácido úrico apresentaram-se significativamente baixos na avaliação pós-operatória (482,34 ± 195,80 mg versus 434,75 ± 158,38 mg, p=0,027). PH urinário, oxalato, cálcio, citrato e magnésio não apresentaram variações significativas entre os períodos pré e pós-operatório. Conclusão: a GV pode levar a alterações importantes no perfil urinário. Entretanto, essas ocorrem de forma muito mais leve que na derivação gástrica em Y de Roux.

ABSTRACT Background: Morbid obesity surgery and related complications have increased with time. Aim: To evaluate the relationship between perioperative complications before discharge and preoperative body mass index and obesity surgery mortality score in laparoscopic sleeve gastrectomy. Method: 1617 patients who met the inclusion criteria were evaluated retrospectively. The patients were examined in terms of demographic data, presence of comorbidities, whether there were complications or not, type of complications and obesity surgery mortality score. Results: Complications were seen in 40 patients (2.5%) and mortality wasn't seen in the early postoperative period before discharge. The mean age of patients with complications was 36.3±10.02 years (19-57) and without complications 34.12±9.54 (15-64) years. The preoperative mean BMI values of patients with and without complications were 45.05±3.93 (40-57) kg/m2 and 44.8±3.49 (35-67) kg/m2 respectively. According to BMI groups 40-45 kg/m2, 45-50 kg/m2 and 50 and over, there was not any statistical significance seen in three groups in terms of complication positivity and major-minor complication rates. There was not any statistical significance seen between the patients with and without major-minor complications and obesity surgery mortality score. Conclusion: There was not any relation between perioperative laparoscopic sleeve gastrectomy complication rates before discharge and BMI and obesity surgery mortality scores.
RESUMO Racional: A cirurgia da obesidade mórbida e complicações relacionadas aumentaram com o tempo. Objetivo: Avaliar a relação entre as complicações perioperatórias antes da alta e o índice de massa corporal pré-operatório e o escore de mortalidade da cirurgia de obesidade na gastrectomia vertical laparoscópica. Método: 1.617 pacientes que atenderam aos critérios de inclusão foram avaliados retrospectivamente. Os pacientes foram examinados quanto aos dados demográficos, presença de comorbidades, ocorrência ou não de complicações, tipo de complicações e escore de mortalidade cirúrgico da obesidade. Resultados: Complicações foram observadas em 40 pacientes (2,5%) e mortalidade não foi observada no período pós-operatório imediato antes da alta. A média de idade dos pacientes com complicações foi de 36,3±10,02 anos (19-57) e sem complicações de 34,12±9,54 (15-64) anos. Os valores médios de IMC pré-operatórios dos pacientes com e sem complicações foram 45,05±3,93 (40-57) kg/m2 e 44,8±3,49 (35-67) kg/m2, respectivamente. De acordo com os grupos de IMC 40-45 kg/m2, 45-50 kg/m2 e 50 e mais, não houve qualquer significância estatística observada em três grupos em termos de positividade de complicações e taxas de complicações maiores-menores. Não houve significância estatística entre os pacientes com e sem complicações maiores e menores e o escore de mortalidade da cirurgia de obesidade. Conclusão: Não houve qualquer relação entre as taxas de complicações da gastrectomia vertical laparoscópica perioperatória antes da alta e os escores de mortalidade da cirurgia de obesidade e IMC.

La gastrectomía vertical laparoscópica es actualmente la cirugía bariátrica más empleada a nivel mundial. Aunque es un procedimiento seguro y efectivo pueden ocurrir complicaciones mayores. En el presente trabajo reportamos el caso de un infarto y absceso esplénico como una rara complicación de esta técnica, que requirió finalmente de esplenectomía como tratamiento definitivo. Caso clínico: Mujer de 22 años con obesidad grado I, a quien se le practicó gastrectomía vertical laparoscópica con buena evolución intrahospitalaria y egreso a las 48 horas. Al 4to día posoperatorio consultó por fiebre, dolor abdominal, taquipnea y taquicardia. Mediante tomografía computada de abdomen se diagnosticó infarto esplénico parcial. Recibió tratamiento médico con remisión inicial de los síntomas, los cuales reaparecieron a la 3era semana. Se reinició el tratamiento médico, esta vez sin respuesta, y con evolución al absceso esplénico. Se decidió esplenectomía como tratamiento definitivo logrando la recuperación completa de la paciente. Conclusión: El infarto esplénico es una complicación infrecuente de la gastrectomía vertical. Su tratamiento inicial es médico, reservando la esplenectomía para los casos que no responden(AU)
Laparoscopic sleeve gastrectomy is currently the most performed bariatric surgery worldwide. Although it is an effective and safe procedure major complications can occur. In the present manuscript we report a case of splenic infarct and abscess as a rare complication of laparoscopic sleeve gastrectomy, finally requiring a splenectomy as a definitive treatment. Case report: A 22 years old woman with grade I obesity underwent laparoscopic sleeve gastrectomy with good hospital evolution and 48 hours discharge. On the 4th postoperative day she return because fever, abdominal pain, tachypnea and tachycardia. By means of a computed tomography a splenic infarct was diagnosed. She received medical treatment with initial remission of symptoms, which reappear at the third week. Medical treatment was restarted, this time without success, and with progression to splenic abscess. We decided a splenectomy as definitive treatment achieving a complete patient recovery. Conclusion: Splenic infarction is a rare complication after sleeve gastrectomy. The treatment is non surgical, reserving the splenectomy for the non responded cases(AU)

ABSTRACT Background: Gastroesophageal reflux (GER) is one of the most common indications for conversion of sleeve gastrectomy (LSG) to laparoscopic Roux-en-Y gastric bypass (LRYGBP). Objective evaluations are necessary in order to choose the best definitive treatment for these patients. Aim: To present and describe the findings of the objective studies for gastroesophageal reflux disease performed before LSG conversion to LRYGBP in order to support the indication for surgery. Method: Thirty-nine non-responder patients to proton pump inhibitors treatment after LSG were included in this prospective study. They did not present GER symptoms, esophagitis or hiatal hernia before LSG. Endoscopy, radiology, manometry, 24 h pH monitoring were performed. Results: The mean time of appearance of reflux symptoms was 26.8+24.08 months (8-71). Erosive esophagitis was found in 33/39 symptomatic patients (84.6%) and Barrett´s esophagus in five. (12.8%). Manometry and acid reflux test were performed in 38/39 patients. Defective lower esophageal sphincter function was observed independent the grade of esophagitis or Barrett´s esophagus. Pathologic acid reflux with elevated DeMeester´s scores and % of time pH<4 was detected in all these patients. more significant in those with severe esophagitis and Barrett´s esophagus. Radiologic sleeve abnormalities were observed in 35 patients, mainly cardia dilatation (n=18) and hiatal hernia (n=11). Middle gastric stricture was observed in only six patients. Conclusion: Patients with reflux symptoms and esophagitis or Barrett´s esophagus after SG present defective lower esophageal sphincter function and increased acid reflux. These conditions support the indication of conversion to LRYGBP.
RESUMO Racional: O refluxo gastroesofágico é uma das indicações mais comuns para a conversão da gastrectomia vertical (SG) em gastroplastia laparoscópica em Y-de-Roux (LRYGBP). Avaliações objetivas são necessárias para escolher o melhor tratamento definitivo para esses pacientes. Objetivo: Apresentar e descrever os achados objetivos da doença do refluxo gastroesofágico realizados antes da conversão do SG para o LRYGBP, a fim de apoiar a indicação cirúrgica. Método: Trinta e nove pacientes não respondedores ao tratamento com inibidores da bomba de prótons após SG foram incluídos neste estudo prospectivo. Eles não apresentavam sintomas de refluxo gastroesofágico, esofagite ou hérnia hiatal antes da SG. Endoscopia, radiologia, manometria, monitoramento de pH 24 horas foram realizados. Resultados: O tempo médio de aparecimento dos sintomas de refluxo foi de 26,8+24,08 meses (8-71). Esofagite erosiva foi encontrada em 33/39 pacientes sintomáticos (84,6%) e esôfago de Barrett em cinco (12,8%). A manometria e o teste de refluxo ácido foram realizados em 38/39 pacientes. A função alterada do esfíncter inferior do esôfago foi observada independentemente do grau de esofagite ou esôfago de Barrett. Em todos esses pacientes, foi detectado refluxo ácido patológico com escores elevados de DeMeester e % de tempo pH<4, mais significativo nos com esofagite grave e esôfago de Barrett. Anormalidades radiológicas SG foram observadas em 35 pacientes, principalmente dilatação da cárdia (n=18) e hérnia hiatal (n=11). Estenose gástrica foi observada em apenas seis pacientes . Conclusão: Pacientes com sintomas de refluxo e esofagite ou esôfago de Barrett após SG apresentam função do esfíncter esofágico inferior defeituosa e aumento do refluxo ácido. Esses sintomas e estudos objetivos apoiam a indicação de conversão para LRYGBP.

La obesidad es el factor que más se asocia a la esteatohepatitis no alcohólica (EHNA). La cirugía bariátrica ha demostrado ser eficaz en la EHNA y junto con el tratamiento de la diabetes mellitus tipo 2 (DMT2) y la dislipidemia, logran una mejoría en las alteraciones de las enzimas hepáticas y de los cambios ecográficos hepáticos. Objetivo: Analizar el efecto de la cirugía bariátrica en pacientes con índice de masa corporal (IMC) ≥ 35 kg/m2 y EHNA. Método: se hizo una investigación retrospectiva de 20 pacientes sometidos a cirugía bariátrica: bypass gástrico en Y de Roux (BPGYR) y gastrectomía vertical (GV) entre 2014 y 2015. Resultados: De los 20 pacientes, 14 fueron intervenidas de BPGYR y 6 de GV; 95% fueron del sexo femenino, con edad promedio de 35,95 ± 8,54 años. Los valores preoperatorios de aspartato aminotransferasa (AST) y alanino aminotransferasa (ALT) de todos los pacientes fue > 30 U/L. Los valores postoperatorios de AST y ALT al año de la cirugía fueron normales en 85% y 80% de los casos respectivamente. No se observaron alteraciones en los niveles pre y postoperatorios de lactato deshidrogenasa (LDH). Todos los pacientes presentaron infiltración grasa hepática moderada la cual se redujo a leve o sin infiltración grasa al año de la cirugía de acuerdo a la evaluación ecográfica. Conclusiones: La cirugía bariátrica demostró tener un impacto favorable en EHNA dado por la mejoría en los niveles de AST, ALT y de la esteatosis hepática corroborada por controles ecográficos(AU)
Obesity is the factor that is most associated with non-alcoholic steatohepatitis (NASH). Bariatric surgery has been shown to be effective in NASH and, along with treatment of type 2 diabetes (T2D) and dyslipidemia, they achieve a significant improvement in liver enzymes and liver ultrasound changes. Objective: To analyze the effect of bariatric surgery in patients with a body mass index (BMI) > 35 kg/m2 and NASH. Method: It was performed a retrospective investigation of 20 patients who underwent bariatric surgery: Roux-en-Y gastric bypass (RYGBP) or sleeve gastrectomy (SG) between 2014 and 2015. Results: Of the 20 patients, 14 underwent BPGYR and 6 GV; 95% were female, with a mean age of 35.95 ± 8.54 years. The preoperative levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) for all patients were >30 U/L. Postoperative levels of AST and ALT one year after surgery were normal in 85% and 80% of cases, respectively. No alterations were observed in pre and postoperative levels of lactate dehydrogenase (LDH). All patients presented moderate hepatic fat infiltration which was reduced to mild or without fat infiltration one year after surgery according to the ultrasonographic evaluation. Conclusions: Bariatric surgery was shown to have a favorable impact on NASH due to the improvement observed in AST and ALT levels, and hepatic steatosis corroborated by ultrasound scans(AU)

ABSTRACT Background: Obesity represents a growing threat to population health all over the world. Laparoscopic sleeve gastrectomy induces alteration of the esophagogastric angle due to surgery itself, hypotony of the lower esophageal sphincter after division of muscular sling fibers, decrease of the gastric volume and, consequently, increase of intragastric pressure; that's why some patients have reflux after sleeve. Aim: To describe a technique and preliminary results of sleeve gastrectomy with a Nissen fundoplication, in order to decrease reflux after sleeve. Method: In the current article we describe the technique step by step mostly focused on the creation of the wrap and it care. Results: This procedure was applied in a case of 45 BMI female of 53 years old, with GERD. An endoscopy was done demonstrating a hiatal hernia, and five benign polyps. A Nissen sleeve was performed due to its GERD, hiatal hernia and multiple polyps on the stomach. She tolerated well the procedure and was discharged home uneventfully 48 h after. Conclusion: N-sleeve is a feasible and safe alternative in obese patients with reflux and hiatal hernia when Roux-en-Y gastric bypass it is not indicated.
RESUMO Racional: A obesidade representa ameaça crescente à saúde da população em todo o mundo. A gastrectomia por laparoscopia induz alteração do ângulo esofagogástrico devido à própria técnica, hipotonia do esfíncter esofágico inferior após secção de fibras musculares da junção, diminuição do volume gástrico e, consequentemente, aumento da pressão intragástrica; é por isso que alguns pacientes têm refluxo após a gastrectomia vertical. Objetivo: Descrever uma técnica e resultados preliminares da gastrectomia vertical com fundoplicatura a Nissen, a fim de diminuir o refluxo após ela. Método: No artigo atual, descrevemos a técnica passo a passo, principalmente focada na criação da válvula e seu cuidado. Resultados: Este procedimento foi aplicado em um caso de mulher com IMC 45 de 53 anos com DRGE. Foi realizada endoscopia demonstrando hérnia hiatal e cinco pólipos benignos. A gastrectomia vertical com Nissen foi realizada devido à DRGE, à hérnia hiatal e aos múltiplos pólipos no estômago. Ela tolerou bem o procedimento e recebeu alta sem intercorrências 48 h depois. Conclusão: A N-gastrectomia vertical (N-sleeve) é alternativa viável e segura em pacientes obesos com refluxo e hérnia hiatal quando não é indicado o desvio gástrico em Y-de-Roux.

Varias publicaciones informan un aumento en la tasa de enfermedad por reflujo gastroesofágico (ERGE) después de la gastrectomía vertical tubular (GVT) o en manga a pesar que no existe aún consenso al respecto. El objetivo de este artículo es mostrar nuestra propia experiencia y de la literatura respecto a los aspectos clínicos de la enfermedad por ERGE después de la gastrectomía vertical tubular. Del análisis de nuestros resultados y de los datos de la literatura, los estudios que evalúan la prevalencia de la enfermedad de reflujo gastroesofágico posoperatorio muestran que la GVT puede provocar síntomas de ERGE de novo o empeoramiento de la ERGE preexistente.
Several publications report an increase in the rate of gastroesophageal reflux disease (GERD) after surgery, although there is still no consensus on this. The aim of this article is to show our own experience and literature regarding the clinical aspects of GERD disease after tubular vertical gastrectomy. From the analysis of our results and data from the literature, studies evaluating the prevalence of postoperative gastro-oesophageal reflux disease show that GVT can cause symptoms of de novo GERD or worsening of pre-existing GERD.

ABSTRACT Background: Laparoscopic sleeve gastrectomy (LSG) is currently the most frequently performed bariatric procedure in Turkey. The goal of weight reduction surgery is not only to decrease excess weight, but also to improve obesity related comorbidities and quality of life (QoL). Aim: To evaluate the impact of LSG on patient quality of life, weight loss, and comorbidities associated with morbid obesity according to the updated BAROS criteria. Methods: Eleven hundred thirty-eight adult patients were undergone to LSG by our bariatric surgery team between January 2013 and January 2016. A questionnaire (The Bariatric Analysis and Reporting Outcome System - BAROS) was published on social media. The data on postoperative complications were collected from hospital database. Results: Number of respondants was 562 (49.4%). Six of 1138 patients(0.5%) had leakage. All patients who had leakage were respondants. The overall complication rate was 7.7%. After a mean period of 7.4±5.3 months(1-30), mean excess weight loss was 71.3±27.1% (10.2-155.4). The respondants reported 772 comorbidities. Of these, 162 (30%) were improved, and 420 (54.4%) were resolved. The mean scores for QoL were significantly increased after LSG (range, p<0.05 to <0.001). Of the 562 patients, 26 (4.6%) were classified as failures; 86 (15.3%) fair; 196 (34.9%) good; 144 (25.6%) very good, and 110 (19.6%) excellent results according to the updated BAROS scoring system. Conclusion: LSG is a highly effective bariatric procedure in the manner of weight control, improvement in comorbidities and increasing of QoL in short- and mid-term.

ABSTRACT Background: Bariatric surgery in Chile has seen an exponential increase in recent years, especially in sleeve gastrectomy. Its use is currently discussed in patients suffering from gastroesophageal reflux disease. Different options have been considered for the management of these patients but up to now laparoscopic Roux-en-Y gastric bypass seems to be the best option. Sleeve gastrectomy plus concomitant fundoplication or hiatal hernia repair also has been suggested in patients having reflux or small hiatal hernia. Aim: To present a cohort of obese patients with gatroesophageal reflux undergoing this procedure, which seeks to provide the benefits of both laparoscopic gastric sleeve (LSG) and antireflux surgery focused on the evaluation of presence of reflux and BMI after surgery, and to compare the result observed in this cohort with a previous group of obese patients without reflux submitted to sleeve gastrectomy alone. Methods: Retrospective case series in 15 patients who underwent this surgery between the years 2003 and 2012. Clinical records were analyzed and values of 24 hr pH monitoring, esophageal manometry and clinical outcome were recorded. Results were compared to a previous series of patients who underwent LSG. No statistical analyses were made. Results: Group A consisted of 15 patients submitted to LSG plus fundoplication. 93% (n=14) were female. Mean age was 46.2 years. Mean preoperative body mass index (BMI) was 33.9. All patients had altered pH monitoring and manometry preoperatively. There was one minor complication corresponding to a seroma. There was no perioperative mortality. Group B consisted of 23 obese patients who underwent LSG. These patients developed de novo reflux, hypotensive LES and esophagitis after the surgery. Group A patients showed improvement in esophageal pH monitoring and manometry at three months. During long-term follow-up, six underwent revision surgery, four for weight regain, one regained weight associated with symptomatic reflux, and one underwent re-intervention for reflux. Conclusions: Good results are observed in the short-term follow up in both reflux resolution and weight loss. Nevertheless, results at long term are discouraging, with 53.3% of the patients requiring revision surgery during follow-up.
RESUMO Racional: A cirurgia bariátrica no Chile tem visto aumento exponencial nos últimos anos, especialmente na gastrectomia vertical. Atualmente, o seu uso é discutido em pacientes que sofrem de refluxo gastroesofágico. Diferentes opções foram consideradas para o gerenciamento desses pacientes, mas até agora o bypass gástrico em Y-de-Roux laparoscópico parece ser a melhor opção. A gastrectomia vertical mais fundoplicatura concomitante ou o reparo da hérnia hiatal também foi sugerido em pacientes com refluxo ou hérnia hiatal pequena. Objetivo: Apresentar uma coorte de pacientes obesos com refluxo gatroesofágico submetidos a esse procedimento, que busca proporcionar os benefícios da gastrectomia vertical laparoscópica (LSG) e da operação antirrefluxo focada na avaliação da presença de refluxo e IMC após a operação, e comparar a o resultado observado nesta coorte com um grupo anterior de pacientes obesos sem refluxo submetido somente à gastrectomia vertical. Métodos: Série de casos retrospectivos em 15 pacientes submetidos à essa operação entre os anos de 2003 e 2012. Os registros clínicos foram analisados e os valores de monitoramento de pH 24 h, manometria esofágica e desfecho clínico foram registrados. Os resultados foram comparados com uma série anterior de pacientes submetidos à LSG. Não foram feitas análises estatísticas. Resultados: O grupo A consistiu em 15 pacientes submetidos a LSG mais fundoplicatura e 93% (n=14) eram mulheres. A idade média foi de 46,2 anos. O índice de massa corporal pré-operatório médio (IMC) foi de 33,9. Todos os pacientes apresentaram monitoração de pH e manometria pré-operatória alteradas. Houve uma complicação menor correspondente a um seroma. Não houve mortalidade perioperatória. O grupo B consistiu de 23 pacientes obesos submetidos à LSG. Esses pacientes desenvolveram refluxo de novo, LES hipotensos e esofagite após a operação. Os pacientes do grupo A apresentaram melhora no monitoramento e manometria do pH esofágico aos três meses. Durante o seguimento em longo prazo, seis foram submetidos à operação revisional, quatro por recuperação de peso, um por peso recuperado associado a refluxo sintomático e um submetido à reintervenção por refluxo. Conclusões: Bons resultados são observados no seguimento em curto prazo na resolução de refluxo e perda de peso. No entanto, os resultados em longo prazo são desencorajadores, pois 53,3% dos pacientes necessitaram de operação revisional durante o acompanhamento.

Patologías esofagogástricas son reconocidas antes y después de procedimientos bariátricos, pero frecuentemente y severamente debatidos. Se realizó un estudio con la finalidad de comparar los hallazgos endoscópicos del aparato digestivo superior con los resultados de anatomía patológica en pacientes sometidos a bypass gástrico laparoscópico en Y de Roux y gastrectomía en manga por obesidad mórbida. Un total de 142 pacientes fueron incluidos en el estudio, todos bajo un régimen de seguimiento. Se hicieron análisis retrospectivos con hallazgos endoscópicos preoperatorios. Los reportes endoscópicos estuvieron disponibles para el total de los pacientes incluidos, asimismo los reportes de biopsias endoscópicas. El promedio de edad fue 34.7 años, 88 (61.9 por ciento) pacientes eran mujeres y 54 (38 por ciento) hombres. El hallazgo endoscópico patológico predominante fue gastritis erosiva 56.3 por ciento (80/142), seguida por gastritis nodular 17.6por ciento (25/142), hernia hiatal tipo I 3.5 por ciento (5/142), esofagitis 3.5 por ciento (5/142), duodenitis inespecífica 2.8 por ciento (4/142), pólipos gástricos 2,8 por ciento (4/142), y 18 estudios normales 12.6 por ciento. En cuanto a resultados de biopsias reportamos 243 hallazgos y el total no se corresponde con el número de casos en vista que algunos pacientes tenían más de una patología. El hallazgo más frecuente fue gastritis crónica 96.4% (137/142), infección por Helicobacter pylori 40.8 por ciento (58/142), hiperplasia foveolar difusa 14.7 por ciento (21/142), hiperplasia foveolar focal 15.4 por ciento (22/142), pólipos hiperplásicos 2.8 por ciento (4/142) y acantosis irregular 0.7 por ciento (1/142). Concluyendo de los 142 pacientes estudiados, solo 18 (12.6 por ciento) estudios resultaron normales, sin embargo, no se corresponden con biopsias indemnes, pero los hallazgos patológicos no tienen relevancia clínica, por lo que ni la endoscopia preoperato.(AU)
Esophagogastric diseases are recognized before and after bariatric procedures, but frequently and severely debated. A study with aim to compare the endoscopic findings of the upper digestive tract with the results of pathology in patients undergoing Roux en Y laparoscopic gastric bypass and sleeve gastrectomy for morbid obesity was performed. A total of 142 patients were included in the study, all under a monitoring regime. Retrospective analysis with preoperative endoscopic findings were made. Endoscopic reports were available for all patients included also reports of endoscopic biopsies. The average age was 34.7 years, 88 (61.9 percent) patients were female and 54 (38 percent) men. The predominant pathological endoscopic finding was erosive gastritis 56.3m percent (80/142), followed by nodular gastritis 17.6 percent (25/142), type I hiatal hernia 3.5 percent (5/142), esophagitis 3.5 percent (5/142), unspecific duodenitis 2.8 percent (4/142), gastric polyps 2.8 percent (4/142), and 18 normal studies 12.6 percent. As biopsy results we report total findings 243 does not correspond to the number of cases in view some patients had more than one pathology. The most common finding was chronic gastritis 96.4 percent(137/142), Helicobacter pyloriinfection 40.8 percent (58/142), foveal diffuse hyperplasia 14.7 percent (21/142), foveal focal hyperplasia 15.4 percent (22/142), hyperplastic polyps 2.8 percent (4/142) and irregular acanthosis 0.7 percent (1/142). In conclusion of the 142 patients studied, only 18 (12.6 percent) studies were normal, however the pathological findings have no clinical relevance, so neither preoperative endoscopy in the obese patient and the histological study of the stomach and duodenum appear to be justified in our population.(AU)

Introducción: La gastrectomía vertical en manga (MG) consiste en resecar el fundus y la curva mayor del estómago preservando la curvatura menor en forma tubular. Estudios reportan aumento de riesgo de enfermedad por reflujo gastro esofágico (ERGE) de novo en pacientes con MG por la eliminación del fundus gástrico, pérdida del ángulo de His,sección de fibras musculares en cincha. Yehoshua demostró disminución de distensibilidad e incremento de presión intragástrica (PIG) después de MG. Pandolfino expuso que la distensibilidad de la unión esófago gástrica (UEG) es indicador del grado de apertura de la misma aumentando la tendencia al reflujo. Objetivos: Evaluar los cambios anatómicos y funcionales de presión y distensibilidad de la UEG mediante impedancia planimétrica (EndoFLIP ®) involucrados en la aparición de reflujo gastroesofágico. Se hipotetizó que los eventos de reflujo ocurren por disminución temporal de la zona de alta presión a nivel de la UEG con aumento del gradiente de presión en sentido gastro esofágico por incremento de la PIG del reservorio y de la distensibilidad de la UEG en presencia de tono normal de la UEG. Pacientes y Métodos: Estudio prospectivo, experimental de cohorte con 23 pacientes sometidos a MG de acuerdo a los criterios establecidos por la ISGC.Fueron excluidos los pacientes con diagnóstico de ERGE y hernia hiatal (HH); y a los incluidos se les realizó gastroscopia y Manometría esofágica de alta resolución (MAR) preoperatoria. Durante la cirugía se midió presión y distensibilidad de la UEG con el sistema EndoFLIP® en 2 momentos: al estabilizarse el neumoperitoneo y una vez finalizada la gastrectomía, incluyendo la medición de presión y distensibilidad del reservorio gástrico. Resultados: Se evaluaron 23 pacientes,16 mujeres, edad promedio: 44 años (29-67). Promedio de Índice de masa corporal (IMC) 39.14 kg/m2. (31.2 - 45). La medición inicial expuso presión del EEI de 32.6 mmHg, y distensibilidad 11.69 mm2/mmHg. La segunda medición mostró presión de 35.8 mmHg y distensibilidad de 15.19 mm2/mmHg. La medición del reservorio gástrico registró presión de 38.9 mm2/mmHg). La prueba de t de Student pareada encontró diferencias significativas en las presiones y distensibilidades post operatorias (p= 0.0357) y (p< 0.0001) respectivamente. Cuando estos valores se correlacionaron con el IMC se observó que los pacientes con menor IMC aumentaron la presión luego de la MG y los pacientes con mayor IMC reportaron el fenómeno inverso, las distensibilidades mostraron muy poca variación antes y después de la MG, por lo cual no hubo asociación entre éstas y el IMC. Conclusión: Existe una relación positiva y media entre las variables con significación estadística (p<0.05), a un nivel de confianza de 95%, diferente a cero, determinando que los factores implicados en la génesis del ERGE posterior a MG están condicionados a una importante elevación de la presión del reservorio gástrico y aumento de distensibilidad de la UEG.
Introduction: Vertical sleeve gastrectomy (VSG) consists in resecting the fundus and the larger curve of the stomach while preserving the lesser curvature in tubular form. Studies report an increasing risk of de novo gastroesophageal reflux disease (GERD) in patients with VSG due to the elimination of the gastric fundus, loss of the His angle, section of muscle fibers in girth. Yehoshua showed decreased distensibility and increased intragastric pressure (IGP) in the reservoir after VSG. Pandolfino stated that the distensibility of the esophagogastric junction (EGJ) is indicative of the degree of opening thereof increasing tendency to reflux.Objectives: To evaluate the anatomical and functional changes in pressure and distensibility of the EGJ by planimetric impedance (EndoFLIP®) involved in the development of gastroesophageal reflux. We hypothesized that reflux events occur by the temporary decrease of the high pressure área at the EGJ with increased pressure gradient in gastroesophageal sense by increasing the reservoirs IGP and the distensibility of the EGJ in the presence of normal EGJ tone. Patients and methods: Prospective cohort pilot study with 23 patients undergoing VSG according to the criteria established by the ISGEPC. Patients with GERD and hiatal hernia (HH) diagnosis were excluded and those included underwent gastroscopy and preoperative high resolution esophageal manometry (HRM). During surgery pressure and distensibility of the EGJ were measured with the EndoFLIP® system at 2 times: once the pneumoperitoneum was stabilized and when the gastrectomy was over, including pressure measurement and distensibility of the gastric pouch. Results: 23 patients were evaluated, 16 wo-men, 44 years old, average age (29-67). Average body mass index (BMI) of 39.14 kg/m2. (31.2 - 45). The initial measure-ment of LES pressure exhibited 32,6 mmHg and distensibility 11,69mm2/mmHg. The second pressure measurement showed 35,8 mmHg and distensibility 15,19 mm2/mmHg. Measuring gastric reservoir pressure recorded 38,9 mm2/mmHg). The paired Students T Test found significant differences in the postoperative pressures and compliances (p = 0.0357) and (p <0.0001) respectively. When these values were correlated with BMI was observed that patients with lower BMI increased after pressure from the VSG and patients with higher BMI reported the reverse phenomenon, the distensibilities showed very little variation before and after the VSG, thus there was no association between these and BMI.Conclusion: There is a positive relationship between the variables with statistical significance (p <0.05), determining that the factors involved in the genesis of GERD after VSG are conditioned to a significant elevation of gastric reservoir pressure,increased distensibility of the EGJ and inverse relationship between the BMI and the EGJ pressure measured by the EndoFLIP®.

Introducción: la obesidad se ha convertido en un problema a nivel mundial. Ecuador no podía ser la excepción y según el INEC, 4 millones de personas en el país padecen de sobrepeso. La cirugía bariátrica ha sido reconocida como un método seguro y eficaz en el tratamiento de la obesidad y sus comorbilidades. Materiales y métodos: con el objetivo de analizar los resultados y complicaciones de la manga gástrica (LSG, por sus siglas en inglés) en el Hospital Carlos Andrade Marín, se realiza un estudio descriptivo retrospectivo, de los pacientes operados entre 2008 y 2013 en el Servicio de Cirugía General del Hospital Carlos Andrade Marín, se realiza un estudio descriptivo retrospectivo, de los pacientes operados entre 2008 y 2013 en el Servicio de Cirugía General del Hospital Carlos Andrade Marín (HCAM). Del total, 309 sujetos, se evaluaron características demográfcas y complicaciones perioperatorias. De un grupo más pequeño, 162 pacientes que tuvieron un seguimiento posoperatorio de al menos un año, se analizó la reducción de peso y resolución de comorbilidades asociadas a la obesidad. Resultados: el 87% de los pacientes tienen un índice de masa corporal (IMC) entre 30 y 40. El promedio de reducción de peso al año de la cirugía fue de 9.5 puntos de IMC. La morbilidad general relacionada al procedimiento fue de 7.2%, con una tasa de fístulas de 4.5%. Se reoperaron 14 pacientes, ya sea por fístula o por sangrado. En cuanto a la morbilidad que se relaciona a la obesidad, más del 60% de pacientes presentaron mejoría. Conclusión: el resultado de este estudio demuestra que la manga gástrica es un excelente procedimiento aplicado al tipo de obesidad que maneja este servicio, la gran mayoría tipo I y II. Se ha logrado llevar a estos pacientes a valores casi normales de IMC al año del procedimiento, con una aceptable morbilidad y con un adecuado manejo de las complicaciones.
Introduction: obesity has become a worldwide problem. Ecuador is not the exception an according to the INEC, 4 million people in the country have overweight. The bariatric surgery has been recognized as a safe and effective treatment for obesity and its comorbidities. Materials and methods: in order to analyze the results and complications of the laparoscopic sleeve gastrectomy (LSG) at the Carlos Andrade Marín Hospital, a descriptive study of patients operated between 2008 and 2013 in the Department of Surgery at the Carlos Andrade Marin Hospital was performed. Of the 309 subjects, demographics and perioperative complications were evaluated. In a smaller group, 162 patients who had a postoperative follow-up of at least one year, weight loss and resolution of comorbidities associated with obesity was analyzed. Results: eighty seven percent (87%) of patients have a body mass index (BMI) between 30 and 40. The average weight loss at one year after surgery was 9.5 BMI points. The overall procedure -related morbidity was 7.2 %, with a 4.5% rate of gastric sleeve fstula. Fourteen patients were operated again due to gastric sleeve bleeding. There were no deaths related to surgery. Regarding morbidity associated with obesity, more than 60% of patients showed improvement. Conclusion: the result of this study shows that gastric sleeve is an excellent procedure applied to the type of obesity of this service, most type I and II. It has managed to bring these patients to near normal values of BMI within a year of the procedure, with acceptable morbidity and proper management of complications.

Background: Laparoscopic sleeve gastrectomy (LSG) is used for the treatment of obesity and may provide gastric tissue for pathological studies. The association of obesity with dyslipidemias, diabetes and cardiovascular disease is of common knowledge. However its association with gastrointestinal diseases and gastritis is less well known. Aim: To analyze the pathological findings of the resected gastric segment during LSG. Material and Methods: Two hundred fifty patients aged 37 +/- 12 years and with a body mass index of 37.7 +/- 3.1 kg/m² (189 women), subjected to LSG, were included in a prospective protocol. Resected gastric segments were sent for a pathological study. Results: A gastric disease was identified in 220 (88 percent) cases. Chronic follicular gastritis was diagnosed in 117 patients (46.8 percent), chronic superficial gastritis in 76 (30.4 percent), chronic nonspecific gastritis in 38 (15.2 percent), intestinal metaplasia in 14 percent (5.6 percent) and in one case (0.4 percent) an early gastric carcinoma. Helicobacterpylori was present in 34 (13.6 percent) patients. Conclusions: This study shows a high prevalence of histopathological gastric lesions detected after the LSG, reaffirming the need for detection of these lesions before surgery.
Introducción: La gastrectomía vertical laparoscópica (GVL) es un procedimiento quirúrgico efectivo en el tratamiento de la obesidad. La obesidad está asociada con algunas comorbilidades como diabetes, dislipidemia y enfermedad cardiovascular, pero también se ha demostrado que tiene efectos potenciales sobre la gastritis y diversas enfermedades gastrointestinales. El objetivo de este estudio es determinar los hallazgos histológicos del segmento gástrico resecado durante la GVL realizada en una serie de pacientes obesos. Material y Método: Entre enero de 2006 y diciembre de 2008, 250 pacientes consecutivos a los que se realizó GVL, fueron incluídos en un protocolo prospectivo. La serie consistió en 189 mujeres (75,6 por ciento) y 61 hombres (24,4 por ciento), con edad promedio de 37,5 +/- 12,1 años. El Índice de Masa Corporal (IMC) promedio fue 37,7 +/- 3,1 kg/m². Resultados: Los resultados histológicos identificaron 220 casos (88 por ciento) con patología gástrica. Se diagnosticó gastritis crónica folicular en 117 pacientes (46,8 por ciento), gastritis crónica superficial en 76 (30,4 por ciento), gastritis crónica inespecífica en 38 (15,2 por ciento), metaplasia intestinal en 14 percent (5,6 por ciento) y en un caso (0,4 por ciento) adenocarcinoma in situ. Helicobacter pylori (HP) estuvo presente en 34 pacientes (13,6 por ciento). Conclusiones: Los hallazgos de este estudio, muestran una prevalencia incrementada de lesiones gástricas histopatológicas detectadas posterior a la GVL, reafirmando la necesidad de una detección de estas lesiones antes de la cirugía.
