Early and severe onset of esophageal dysfunction after laparoscopic sleeve gastrectomy: a case report and review of literature.

After bariatric surgery one of the most common complications is dysphagia. The etiology of this disease has not been fully elucidated but it is known that it may be due to structural changes due to surgery. This case describes a 65-year-old female with early and severe onset of dysphagia following laparoscopic sleeve gastrectomy. The patient's final diagnosis was postobesity surgery esophageal dysfunction and laparoscopic proximal gastrectomy with esophagojejunal Roux-en-Y anastomosis was performed. Physicians should be aware of this condition in order to offer early diagnosis and treatment.

Vanek's tumor: a rare differential diagnosis of colonic submucosal lesions.

Gastrointestinal submucosal lesions represent a diagnostic challenge, including benign or malignant lesions, so they are identified more accurately by histopathological study accompanied by immunohistochemistry. This is a case of a 21-year-old man with a bleeding submucosal lesion in the cecum. The patient underwent a right colectomy. Microscopic finding was compatible with Vanek's tumor.

Nasogastric versus nasojejunal tube feeding for severe acute pancreatitis: A systematic review of randomized controlled trials.

Early enteral nutrition through a feeding tube is essential for the management of severe acute pancreatitis (SAP). Nasojejunal tube nutrition has been preferred on the assumption that it provided pancreatic rest in comparison to the nasogastric tube. However, nasojejunal tube placement is complex, may delay feeding initiation and can increase hospital costs. Our aim was to compare the efficacy and safety of enteral feeding with a nasogastric tube versus nasojejunal tube in patients with SAP. We searched four databases (PubMed, Web of Science, Scopus, and Embase) until December 1, 2022. We included randomized controlled trials (RCTs) comparing enteral feeding by nasogastric and nasojejunal tubes in patients with SAP. Primary outcome was all-cause mortality. Secondary outcomes were organ failure, infection, complications, surgical intervention, duration of tube feeding and length of hospital stay. Risk of bias assessment was completed independently by two investigators using the Cochrane RoB 2.0 tool. We performed random effects model meta-analyses using the inverse variance method. Effect measures were reported as relative risks (RR) and their 95% CIs for dichotomous outcomes and mean differences (MD) and their 95% CIs for continuous outcomes. We included four RCTs involving 192 patients with SAP. The mean ages ranged between 36 and 62 years old. There was no significant difference in all-cause mortality between the nasogastric and nasojejunal feeding arms (18/98 vs. 23/93; RR 1.34, 95%CI 0.77-2.30; p=0.30). There were no significant differences in all secondary outcomes between feeding arms. There were three RCTs with some concerns of bias, in the randomization process. In conclusion, in patients with SAP, enteral feeding delivered by nasogastric tube was as efficacious and safe as nasojejunal tube. Further randomized controlled trials with more participants and better design are needed to confirm these findings.

A rare case of colonic malakoplakia at the bottom of an adenoma mimicking an invasive carcinoma.

We present the case of a 47-year-old man with a history of refractory multiple myeloma who was referred to our hospital for the presence of a colonic lesion suspected of having signs of deep submucosal invasion. After a surgical resection, the histological study revealed that it was a case of malakoplakia that had developed at the base of a tubular adenoma.

La nutrición enteral temprana a través de una sonda de alimentación es esencial para el tratamiento de la pancreatitis aguda severa (PAS). Se ha preferido la nutrición por sonda nasoyeyunal, bajo el supuesto de que proporciona descanso pancreático en comparación con la sonda nasogástrica. Sin embargo, la colocación de la sonda nasoyeyunal es compleja, puede retrasar el inicio de la alimentación y aumentar los costos hospitalarios. Nuestro objetivo fue comparar la eficacia y seguridad de la alimentación enteral con sonda nasogástrica versus sonda nasoyeyunal en pacientes con PAS. Se realizaron búsquedas en cuatro bases de datos (PubMed, Web of Science, Scopus y Embase) hasta el 1 de diciembre de 2022. Se incluyeron ensayos controlados aleatorios (ECA) que compararon la alimentación enteral mediante sondas nasogástricas y nasoyeyunales en pacientes con PAS. El resultado primario fue la mortalidad por todas las causas. Los resultados secundarios fueron insuficiencia orgánica, infección, complicaciones, intervención quirúrgica, duración de la alimentación por sonda y duración de la estancia hospitalaria. Dos investigadores completaron de forma independiente la evaluación del riesgo de sesgo mediante la herramienta Cochrane RoB 2.0. Realizamos metanálisis de modelos de efectos aleatorios utilizando el método de varianza inversa. Las medidas del efecto se informaron como riesgos relativos (RR) y sus IC del 95% para resultados dicotómicos y diferencias de medias (DM) y sus IC del 95% para resultados continuos. Se incluyeron cuatro ECA con 192 pacientes con PAS. La edad media osciló entre 36 y 62 años. No hubo diferencias significativas en la mortalidad por todas las causas entre los brazos de alimentación nasogástrica y nasoyeyunal Cambiar lo resaltado por: (18/98 vs. 23/93; RR 1.34, 95%CI 0.77-2.30; p=0.30). No hubo diferencias significativas en todos los resultados secundarios entre los brazos de alimentación. Hubo tres ECA con algunas preocupaciones de sesgo en el proceso de asignación aleatorizado. En conclusión, en pacientes con PAS, la alimentación enteral administrada por sonda nasogástrica fue tan eficaz y segura como la sonda nasoyeyunal. Se necesitan más ensayos controlados aleatorios con más participantes y mejor diseño para confirmar estos hallazgos.

Short-term outcomes of endoscopic submucosal dissection for the treatment of superficial gastric neoplasms in non-Asian countries: a systematic review and meta-analysis.

Background: Endoscopic submucosal dissection (ESD) is now considered the standard treatment for early gastric cancer (EGC). However, the widespread adoption of ESD in western countries has been slow. We performed a systematic review to evaluate short-term outcomes of ESD for EGC in non-Asian countries. Methods: We searched 3 electronic databases from inception until October 26, 2022. Primary outcomes were en bloc, R0 and curative resections rate by region. Secondary outcomes were overall complications, bleeding, and perforation rate by region. The proportion of each outcome, with the 95% confidence interval (CI), was pooled using a random-effects model with the Freeman-Tukey double arcsine transformation. Results: Twenty-seven studies from Europe (n=14), South America (n=11) and North America (n=2) were included, involving 1875 gastric lesions. Overall, en bloc, R0, and curative resection rates were achieved in 96% (95%CI 94-98%), 85% (95%CI 81-89%), and 77% (95%CI 73-81%) of cases, respectively. Considering only information from lesions with adenocarcinoma, the overall curative resection was 75% (95CI 70-80%). Bleeding and perforation were observed in 5% (95%CI 4-7%) and 2% (95%CI 1-4%) of cases, respectively. Conclusion: Our results suggest that short-term outcomes of ESD for the treatment of EGC are acceptable in non-Asian countries.

Endoscopic submucosal dissection versus surgery for patients with undifferentiated early gastric cancer.

BACKGROUND AND AIMS: endoscopic submucosal dissection (ESD) is the standard treatment for differentiated early gastric cancer (EGC). However, its expanded indication for undifferentiated EGC is controversial. In this study, the efficacy and safety of ESD versus surgery in patients with undifferentiated EGC were compared. METHODS: four databases were searched until February 24, 2022, for studies assessing patients with undifferentiated EGC that met an expanded indication for endoscopic resection and who were treated with ESD or surgery. Primary outcomes were all-cause mortality and any recurrence. Secondary outcomes were complete histological resection, local recurrence, metachronous recurrence, synchronous recurrence, distant metastasis, overall complication, and bleeding. All meta-analyses were performed using a random-effects models. Unadjusted (risk ratio [RR]) and adjusted (aRR and hazard ratio [aHR]) estimates with 95 % confidence interval (CI) were calculated. RESULTS: seven cohort studies were included (n = 2637). The use of ESD was significantly associated with higher all-cause mortality compared to surgery (RR, 2.17; 95 % CI, 1.24-3.81); adjusted all-cause mortality effects were not significant (aRR, 2.28; 95 % CI, 0.95-5.47 and aHR, 1.97; 95 % CI, 0.85-4.53). ESD was associated with a higher risk of any recurrence using unadjusted (RR, 5.24; 95 % CI, 1.49-18.46) and adjusted (aRR, 7.89; 95 % CI, 1.52-40.95 and aHR, 3.73; 95 % CI, 1.17-11.90) estimates. The risk of local recurrence, synchronous recurrence and bleeding were significantly higher for ESD versus surgery. No significant differences were found for other secondary outcomes. CONCLUSIONS: although ESD is associated with a higher risk of any recurrence, adjusted all-cause mortality is similar during follow-up. Overall complications were similar between ESD and surgery.

An unusual case of extensive polypoid high-grade dysplasia in Barrett's esophagus

Barrett's esophagus (BE) is a known precursor of dysplasia and adenocarcinoma. Endoscopic resection and surgery are the techniques used to treat these kinds of lesions. However, endoscopic resection is considered the first choice for the management of superficial lesions. Dysplasia in BE most commonly appears like a flat lesion but here we describe an unusual case of dysplasia and superficial adenocarcinoma looking like an extensive polypoid lesion.

El esófago de Barrett (EB) es un precursor conocido de displasia y adenocarcinoma. La resección endoscópica y la cirugía son las técnicas utilizadas para tratar este tipo de lesiones. Sin embargo, la resección endoscópica se considera la primera opción para el manejo de las lesiones superficiales. La displasia en EB aparece más comúnmente como una lesión plana, pero aquí describimos un caso inusual de displasia y adenocarcinoma superficial que parece una lesión polipoide extensa.

Metástasis gástrica de tumor de células germinales mixto primario testicular: reporte de caso / Gastric metastasis of primary testicular mixed germ cell tumor: A case report

RESUMEN El cáncer de testículo es el tumor sólido más común en los varones de 15 a 29 años. Puede producirse metástasis por vía hematógena o linfática a distintos órganos como pulmón e hígado (usuales) y estómago (inusual). Se presenta el caso de un varón de 30 años que cursa con hemorragia digestiva alta por dos úlceras en el cuerpo gástrico con histología de neoplasia maligna indiferenciada de células pequeñas. En las tomografías se observa tumor testicular derecho con implantes secundarios en cerebro, pulmón, hígado y bazo. Se estudia β-HCG (35 5354 mUI/ml), AFP (500 ng/mL) y DHL (1669 UI/L). Se realiza una orquiectomía radical derecha y se concluyeque es un tumor de células germinales primario de testículo derecho de estadio clínico IIIC por metástasis hepática, esplénica, pulmonar, gástrica y cerebral.

ABSTRACT Testicular cancer is the most common solid tumor in men between ages 15 and 29. It can metastasize through the hematogenous or lymphatic routes to different organs such as the lung and liver (common) and the stomach (uncommon). We present the case of a 30-year-old male patient with upper gastrointestinal bleeding due to two ulcers in the stomach body with histology of unspecified small-cell malignant neoplasm. CT scans showed a right testicular tumor with secondary implants in the brain, lung, liver and spleen. β-HCG (35,5354 mIU/mL), AFP (500 ng/mL) and LDH (1,669 IU/L) tests were conducted. A right radical orchiectomy was performed. It is concluded that this was a clinical stage IIIC primary germ cell tumor of the right testis due to liver, spleen, lung, gastric and brain metastases.

Esofagitis disecante superficial: entidad subdiagnosticada en pacientes pluripatológicos

Paciente de 76 años con múltiples comorbilidades presenta sintomatología gastrointestinal, donde la endoscopía digestiva alta revela mucosa esofágica "acartonada" en tercio distal, que a la toma de biopsia se produce esfacelación de 20 mm de largo por 6 mm de ancho, con sangrado que se autolimita. Muestra patológica es compatible con Esofagitis Disecante Superficial (EDS). Esta es una entidad poco frecuente descrita por primera vez en 1800, caracterizada endoscópicamente por desprendimiento de mucosa en tiras verticales como "cinta de papel de regalo", que se confirma mediante patología con una mucosa "bitonal", compuesta por una capa superficial eosinofílica y una zona basofílica de apariencia normal. Puede estar acompañada de inflamación mínima focal. La etiopatogenia no es clara; sin embargo, tiene buena respuesta a inhibidores de bomba de protones (IBPs). En nuestro caso la paciente presentaba todas las características de EDS, y ante su baja frecuencia reportada, se realizó revisión de literatura y discusión de esta rara entidad.

A 76-year-old patient presents multiple comorbidities and gastrointestinal symptoms. The upper gastrointestinal endoscopy exam reveals distal stiffness esophageal mucosa. A biopsy was taking creating sloughing of 20 mm long by 6 mm wide with self-limited bleeding. Specimen is compatible with Esophagitis Dissecans Superficialis (EDS). This is a rare entity first described in 1800, characterized endoscopically by mucosal detachment in vertical strips like "gift paper tape", which is confirmed by pathology with a mucosa with "two tones", composed of a eosinophilic superficial layer and a normal-appearing basophilic area. It may be accompanied by minimal focal inflammation. The etiopathogenesis is not clear; however, it has a good response to proton pump inhibitors (PPIs). In our case, the patient presented all the characteristics of EDS, and given its low reported frequency, a review of the literature and discussion of this rare entity was performed.

Efficacy and Safety of Endoscopic Submucosal Dissection for Superficial Gastric Neoplasms: A Latin American Cohort Study.

BACKGROUND/AIMS: Endoscopic submucosal dissection (ESD) is the preferred technique for treating early gastric cancer (EGC). However, very few studies have been conducted in South America. This study aimed to assess the efficacy and safety of ESD for EGC. METHODS: We analyzed data from a prospective cohort from 2013 to 2020. A total of 152 superficial gastric neoplasms that fulfilled the absolute or expanded criteria for ESD were included. Outcomes were en bloc, R0, and curative resection rates, incidence of adverse events, and length of procedure. RESULTS: The age of the enrolled patients was 68.4±11.3 years. The number of included patients based on the absolute and expanded indications was 150 and 2, respectively. En bloc, R0, and curative resections were achieved in 98.0%, 96.1%, and 89.5% of the cases, respectively. Bleeding and perforation were reported in 5.9% and 6.6% of the cases, respectively. Histopathological examination revealed lowgrade dysplasia, high-grade dysplasia, well-differentiated adenocarcinoma, and poorly differentiated adenocarcinoma in 13, 20, 117, and 2 cases, respectively. CONCLUSION: Our study shows that ESD performed by properly trained endoscopists in reference centers is safe and effective, with comparable therapeutic outcomes to those reported in the Eastern series.

Impact of the COVID-19 pandemic in the time to endoscopy in patients with upper gastrointestinal bleedin.

INTRODUCTION: During the COVID-19 pandemic, endoscopic procedures are associated with a high risk of SARS-CoV-2 infection. However, in cases of upper gastrointestinal bleeding (UGIB), priority should be given to an early endoscopy. OBJECTIVE: The main objective was to compare the time since arrival at the hospital and the performance of the endoscopy between both groups. MATERIALS AND METHODS: We performed a retrospective study. Data contains information of patients who attended to the hospital with UGIB and underwent an endoscopy between October 19th, 2019 and June 6th, 2020. Patients were divided into 2 phases: pre-pandemic and pandemic. The time between arrival at the hospital and the performance of the endoscopy in both phases were compared as well as other indicators such hospital stay and in-hospital mortality. RESULTS: With information from 219 patients, the median age was 69 years. 154 and 65 endoscopies were performed in pre-pandemic and pandemic phase, respectively. The time between arrival at the hospital and the performance of the endoscopy was significantly longer during the pandemic (10.00 vs. 13.08 hours, p-value = 0.019). Nevertheless, there were no significant differences in hospital stay or mortality. CONCLUSION: The management of patients with UGIB during the COVID-19 pandemic is complex and requires the application of clinical judgment to decide the best timing to perform an endoscopy without affecting patient care.
