Ausencia de toracotomía mediante la sutura manual intratorácica y la extracción transabdominal de la pieza quirúrgica durante la esofagectomía robótica de Ivor Lewis / Absence of thoracotomy by intrathoracic manual suture and transabdominal removal of surgical specimen during Ivor Lewis robotic esophagectomy

En el tratamiento quirúrgico del cáncer de esófago, la cirugía robótica permite realizar una anastomosis manual intratorácica de manera más sencilla, rápida y cómoda para el cirujano que la cirugía abierta y la cirugía mínimamente invasiva tradicional. Con ello evitamos el uso de instrumentos de autosutura, algunos de los cuales precisan una pequeña toracotomía para su introducción. No obstante, la extracción de la pieza exige la práctica de esa toracotomía, de tamaño variable, y que puede asociar dolor torácico intenso. Describimos una sencilla modificación técnica del Ivor Lewis robótico clásico que permite la extracción de la pieza quirúrgica por una mínima incisión abdominal, evitando la necesidad de fracturar costillas de forma controlada, así como las posibles secuelas de practicar una incisión en la pared torácica.(AU)

In the surgical treatment of esophageal cancer, robotic surgery allows performing an intrathoracic hand-sewn anastomosis in a simpler, faster and more comfortable way for the surgeon than open surgery and traditional minimally invasive surgery. With this, we avoid the use of self-suture instruments, some of which require a small thoracotomy for their introduction. However, the retrieval of the specimen requires the practice of this thoracotomy, of variable size, that can be associated with intense chest pain. We describe a technical modification of the classic robotic Ivor Lewis that allows removal of the surgical piece through a minimal abdominal incision, thus avoiding controlled rib fracture, as well as the possible sequelae of making an incision in the chest wall.(AU)

Esophageal stricture as an initial manifestation of Crohn's disease.

Crohn's disease located in the esophagus is rare, being exceptional as the initial manifestation of the disease. Erosive ulcerative esophagitis, stricture and fistula are forms of presentation, as in other esophageal pathologies, so the differential diagnosis is broad. The histologic features of esophageal Crohn's disease can be nonspecific and increase the diagnostic challenge. Esophageal Crohn's disease should be included in the differential diagnosis of esophageal strictures and may require esophagectomy if medical-endoscopic treatment is not effective.

[Influence of the lockdown due to COVID-19 on weight-loss results during the first year after sleeve gastrectomy]. / Influencia del confinamiento por COVID-19 en los resultados ponderales durante el primer año tras la gastrectomía vertical.

INTRODUCTION: COVID-19 pandemic has lead to lockdown of population in many countries. In Spain, the state of alarm was established from March 15 to June 20, 2020. Usually this fact decreased people's mobility and physical activity, in addition to producing or exacerbating psychological disorders. Our aim was to determine the influence that this condition had over the short-term ponderal results of patients undergoing laparoscopic vertical gastrectomy from May 2019 to May 2020. METHODS: Case-control study for comparing the percentage of excess weight lost (%EWL) and the percentage of total weight lost (%TWL) of patients that underwent a VG during the last year, so they were affected by lockdown in April and part of March 2020 (group 1), to the %EWL and %TWL of a control group (group 2), obtained from our previous series. RESULTS: The mean %EWL in group 1 is 47,37 ± 18,59 and in group 2 is 51,13 ± 17,59, being p = 0,438. Meanwhile, the mean %TWL in group 1 is 21,14 ± 8,17 and in group 2 is 24,67 ± 8,01, with p = 0,115. CONCLUSIONS: Population lockdown by COVID-19 did not get worse short-term results of vertical gastrectomy. More studies with a larger number of patients are necessary to draw firm conclusions.

Influencia del confinamiento por COVID-19 en los resultados ponderales durante el primer año tras la gastrectomía vertical / Influence of the lockdown due to COVID-19 on weight-loss results during the first year after sleeve gastrectomy

Introducción: La pandemia por COVID-19ha obligado al confinamiento de la población en muchos países. En España, el estado de alarma se estableció desde el 15 de marzo al 20 de junio del 2020. Este hecho, por lo general, disminuyó la movilidad y la actividad física de las personas, además de producir o exacerbar alteraciones psicológicas. Nuestro objetivo es analizar la influencia que esta situación ha ejercido sobre los resultados ponderales a corto plazo de los pacientes tratados mediante una gastrectomía vertical laparoscópica entre mayo del 2019 y mayo del 2020. Métodos: Estudio de casos y controles donde se compararon el porcentaje de exceso de peso perdido (%EWL) y el porcentaje de peso total perdido (%TWL) de los pacientes intervenidos en el último año y a los que ha afectado el confinamiento durante el mes de abril y parte de marzo del 2020 (grupo 1; n=20), con el de un grupo control (grupo 2; n=40) de nuestra casuística previa. Resultados: El %EWL medio en el grupo 1 es de 47,37±18,59 y en el grupo 2 es de 51,13±17,59, siendo la p=0,438. Por su parte, el %TWL medio en el grupo 1 es de 21,14±8,17 mientras que en el grupo 2 es de 24,67±8,01, resultando la p=0,115. Conclusiones: El confinamiento de la población por COVID-19 no empeoró los resultados ponderales a corto plazo de la gastrectomía vertical. Son necesarios más estudios con un mayor número de pacientes para obtener conclusiones más sólidas. (AU)

Barrett's esophagus: "All diseases are divine and all are human".

Barrett's esophagus (BE) is a controversial condition. The significance of this condition lies in its premalignant potential, so it is important that clinically applicable biomarkers be identified for early detection and targeted prevention. Dysplasia is currently used as main biomarker, but others most recently surveyed in cancer also include microRNAs. Classically, BE was considered to be an acquired disease related to pathological gastroesophageal acid and bile reflux. However, some cases are associated with genetic predisposition, representing an inherited, familial form of BE. The actual gene, or genes, involved in this condition have not yet been identified. Main therapeutic options include medical treatment and antireflux surgery. Both types of treatment are equally efficient in controlling symptoms and neither is able to cause the metaplastic segment to disappear, which is why the risk of malignancy remains. However, we may use endoscopic radiofrequency to eradicate BE and replace it by the typical squamous epithelium of the esophagus. The currently accepted indications of radiofrequency in BE include low- and high-grade dysplasia, but not Barrett's esophagus without dysplasia. In conclusion, BE may have two different presentations: environmental ("human", reflux) or sporadic BE, which is the most common form, and genetic ("divine", inherited) or familiar BE, less common but with a greater risk for malignancy. As they might be two different diseases, surveillance programs and treatments should also be different.

Evolución del reflujo gastroesofágico tras la gastrectomía vertical laparoscópica. Estudio radiológico, manométrico y pH-métrico / Evolution of gastroesophageal reflux after laparoscopic vertical gastrectomy. A radiographic, manometric and pH-metric study

Introducción: la relación entre la gastrectomía vertical laparoscópica (GVL) y el reflujo gastroesofágico (RGE) es aún controvertida, por lo que su investigación tiene gran interés para llegar a conclusiones definitivas. Nuestro objetivo es determinar si la GVL modifica el RGE pH-métrico de los pacientes obesos y, en caso de que así sea, analizar algunos factores que pudieran explicarlo. Pacientes y métodos: incluimos los primeros 26 pacientes que recibieron una GVL en nuestro centro. Se realizaron un tránsito baritado, una pH-metría ambulatoria de 24 horas y una manometría intraluminal esofágica (MIE) con cuatro canales previamente y al año de la operación. Resultados: de los datos pH-métricos, el índice de DeMeester mostró un aumento significativo (p = 0.028) tras la intervención, mientras que los demás parámetros fueron similares. Por otra parte, se observó que el 50% de los pacientes con RGE pH-métrico preoperatorio mostraron tasas normales al año de la operación. En la MIE objetivamos que la presión del esfínter esofágico inferior (EEI) disminuyó, así como la amplitud media de las ondas en el tercio distal esofágico (p = 0,007 y p = 0,025, respectivamente). En el estudio radiológico la tasa de hernias de hiato "de novo" fue del 36,4%. Conclusión: la GVL determina un aumento leve del RGE, probablemente relacionado con la aparición de hernias de hiato así como con una disminución de la presión del EEI y de la capacidad de barrido esofágico. Sin embargo, no debe contraindicarse la GVL a pacientes con RGE preoperatorio pH-métrico pues puede negativizarse tras la operación

Introduction: the relationship between laparoscopic vertical gastrectomy (LVG) and gastroesophageal reflux (GER) is still controversial. Therefore, its study is of great interest in order to obtain definitive conclusions. The goal of the study was to establish whether LVG modifies pH-metric GER in obese patients and to analyze the associated factors. Patients and methods: the first 26 patients who underwent LVG in our institution were enrolled in the study. A barium swallow, 24-hour ambulatory pH-metry and four-channel intraluminal esophageal manometry (IEM) were all performed before and one year after surgery. Results: among the pH-metric data, there was a significant increase in the DeMeester index after the procedure (p = 0.028), while other parameters remained unchanged. Furthermore, 50% of patients with preoperative pH-metric GER had normal values at one year after surgery. IEM showed a decrease in lower esophageal sphincter (LES) pressure and in the mean wave amplitude at the distal third of the esophagus (p = 0.007 and p = 0.025, respectively). The rate of newly-developed hiatal hernias in the radiographic study was 36.4%. Conclusion: LVG mildly increases GER, which is likely related to the development of hiatal hernias and a decrease in LES pressure and esophageal sweep. However, LVG should not be contraindicated for patients with preoperative pH-metric GER, as this may clear after the procedure

¿Está indicada la gastrectomía profiláctica en pacientes sanos portadores del gen CDH1 para el cáncer gástrico difuso hereditario? / Is prophylactic gastrectomy indicated for healthy carriers of CDH1 gene mutations associated with hereditary diffuse gastric cancer?

Introducción: el cáncer gástrico difuso hereditario (CGDH) constituye uno de los síndromes de cáncer hereditario recientemente comunicados. Aquellos pacientes con sospecha de CGDH deben ser vigilados con endoscopia y toma múltiples de biopsias. Como alternativa, algunos autores proponen la realización de gastrectomía profiláctica (GP) en los portadores de la enfermedad. El objetivo de este trabajo es presentar nuestra experiencia con una familia portadora de la mutación CDH1 a los que se realizó una GP. Pacientes y métodos: nuestro caso índice corresponde a una mujer de 34 años que se diagnosticó de un adenocarcinoma gástrico difuso con carcinomatosis masiva. Presentaba antecedentes familiares de adenocarcinoma gástrico en siete ascendientes. Se realizó un estudio genético mediante secuenciación de CDH1, en el cual se encontró la mutación c1577G>A en el exón 11 del gen CDH1. Resultados: esta mutación estaba también presente en otros seis familiares de la paciente, a los que se les realizó una gastrectomía profiláctica. La anatomía patológica de los estómagos de estos pacientes informó de múltiples focos microscópicos de adenocarcinoma en cinco de ellos, a pesar de que en las numerosas endoscopias realizadas antes de la cirugía no fueron detectados. Conclusiones: recomendamos realizar una gastrectomía profiláctica en los pacientes portadores del gen CDH1 a pesar de ausencia de lesiones tumorales en el screening endoscópico

Introduction: hereditary diffuse gastric cancer (HDGC) is a recently reported hereditary cancer syndrome. Patients with suspected HDGC must be under surveillance via endoscopy and multiple biopsies. As an alternative, some studies suggest prophylactic gastrectomy (PG) for disease carriers. The goal of this article was to report our experience with a CDH1 mutation positive family who underwent PG. Patients and methods: the index case was a 34-year-old female diagnosed with diffuse gastric adenocarcinoma and massive carcinomatosis. There was a family history of gastric adenocarcinoma in seven family members. A genetic study identified the c.1577G>A mutation, in exon 11 of the CDH1 gene via sequencing analysis. Results: this mutation was also present in other six family members, who subsequently underwent prophylactic gastrectomy. The pathology study of resected gastric segments revealed multiple microscopic foci of adenocarcinoma in five of these individuals. These foci were not detected in the multiple endoscopies performed before surgery. Conclusions: we recommend prophylactic gastrectomy for CDH1 mutation carriers even in the absence of lesions during endoscopic screening

[Splenic late infarction after laparoscopic gastrectomy: a case report]. / Infarto esplénico tardío tras gastrectomía vertical laparoscópica: a propósito de un caso.

INTRODUCTION: Laparoscopic gastrectomy has emerged in recent years as an effective technique for the treatment of morbid obesity due to low mortality morbidity rates. Its complications include dehiscence suture line, and others such as splenic infarction. We discuss a case of splenic infarction after laparoscopic gastrectomy. CLINICAL CASE: 45 year old male with a BMI of 37.8 kg/m2, diabetes-II for 15 years, the last five in treatment with insulin, a fasting blood glucose around 140mg/dl, HbA1c of 7.3mg/dl and microangiopathy diabetic nephropathy. The patient underwent a laparoscopic sleeve gastrectomy and he was discharged from hospital 48hours later. 1 month later he presented at the hospital for epigastric pain and fever up to 40° C. An intra abdominal abscess was detected and there was no leakage. The spleen was normal. He was treated with radiological drainage. 9 months later the patient consulted again due to epigastric pain in upper left quadrant, associated with low-grade fever. Thoraco-abdominal CT images compatible with splenic infarction. Currently patient remains asymptomatic one year after surgery. DISCUSSION: Laparoscopic sleeve gastrectomy is one of the most popular procedures of bariatric surgery. Less common complications include abscess and the splenic infarction. Usually patients are asymptomatic, but sometimes cause fever and pain. Initial treatment should be conservative. Only in selected cases, would splenectomy be indicated. CONCLUSIONS: Splenic infarction is usually an early complication, but we should keep it in mind as a long term complication for patients with persistent fever and abdominal pain after laparoscopic gastrectomy.
