[Endoscopic submucosal dissection in undifferentiated early gastric cancer: evaluation of the first cases and analysis of its application as an absolute indication in Peru].

Unlabelled: Endoscopic submucosal dissection (ESD) is the technique of choice in the management of early gastric cancer. Recently, it is also considered as an absolute indication in selected cases of early undifferentiated gastric cancer (U-EGC).

Objectives: In the present study, the first documented cases of ESD in patients with U-EGC are presented and analyzed.

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.

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.

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.

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.

[Esophagitis dissecans superficialis: subdiagnosed entity in multi-morbid patients].

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.

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.

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.

[Clinical practice guidelines for diagnosis and management of Helicobacter pylori infection in gastroduodenal diseases of the Peruvian Health Social Security (EsSalud)].

Introduction: This article summarizes the evidence-based recommendations of the clinical practice guide (CPG) for the diagnosis and management of Helicobacter pylori infection in gastroduodenal diseases.

Methods: For the provision of these recommendations, a guideline development group (local GDG) was established, including medical specialists andmethodologists that formulated seven clinical questions. Systematic searches of systematic reviews and -when it was considered pertinent- primary studies were conducted in PubMed and CENTRAL during December 2017 and July 2019.

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.

Primary squamous cell carcinoma of the sigmoid colon: a case report and literature review.

Primary squamous cell carcinoma of the colon is extremely rare. The etiology is poorly understood, and currently, there are different hypotheses about the origin of this malignant neoplasm. Here, we report a case of an 87-year-old male with a moderately-differentiated nonkeratinizing squamous cell carcinoma of the colon.

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.

Closure of colonic deep mural injury and perforation with endoclips.

Introduction: colorectal perforations are one of the most feared complications after performing an endoscopic resection. The use of endoclips is considered for the management of these complications.

Objectives: to evaluate the efficacy and safety of the use of endoclips in the management of perforations and deep mural injuries that occur after an endoscopic colorectal resection.

[Adherence to institutional clinical practice guideline on managing upper gastrointestinal bleeding, in a hospital in Lima - Peru].

Introduction: In 2018, the Clinical Practice Guideline (CPG) for the Evaluation and Management of upper gastrointestinal bleeding (UGB) was published by the Social Security of Peru (EsSalud). It provides evidence-based statements to optimize the management of these patients.

Objective: To evaluate the adherence to the statements of the CPG at the Edgardo Rebagliati Martins National Hospital (HNERM) of EsSalud (Lima, Peru).

[Type 1 autoimmune pancreatitis: a case report].

Autoimmune pancreatitis (PAI) is a rare pathology and an entity to consider in the differential diagnosis of obstructive jaundice and pancreatic mass. It is a chronic inflammatory disease of the pancreas with established clinical, radiological, serological and histopathological characteristics. The treatment is based on the use of corticosteroids and usually has a good response, with complete resolution of clinical, analytical and radiological parameters.

[Safety and efficacy of the use of self-expanding metal stents in the management ofunresectable malignant biliary stenosis].

Background: In recent years there has been an increase in the use of self-expanding metallic stents (SEMS) in patients with unresectable malignant stenosis of the bile duct. However, in Peru there are no reports on the safety and efficacy of this procedure.

Objective: To evaluate the safety and efficacy of the use of SEMS in the palliative management of malignant stenosis of the bile duct.

[Neoendocrine carcinoma of the esophagus: report of a case].

Neuroendocrine carcinoma of esophagus represents less than 2% of cases of cancer of the esophagus. This presentation is extremely unusual, as this type of carcinoma typically presents with greater frequency in bronchopulmonary regions. The symptoms are usually associated with esophageal obstruction and include odynophagia, dysphagia and weight loss and are not usually associated with Carcinoid syndrome.

Focal Intramucosal Adenocarcinoma Occurring in Gastric Hyperplastic Polyps Treated with Endoscopic Mucosal Resection.

Hyperplastic polyps are the most frequent benign epithelial gastric polyps. Although they are considered nonneoplastic, some cases have been reported with focal adenocarcinoma. We present the case of a 59-year-old woman with a sessile lesion of 15 mm on the distal gastric body associated with an extensive atrophic gastritis.
