[Pan American Crohn's and Colitis Organization (PANCCO) and the Interamerican Society of Endoscopy (SIED) consensus on endoscopy in inflammatory bowel disease].

Introduction: Endoscopy plays a fundamental role in inflammatory bowel disease (IBD), and becomes essential in diagnosis, treatment monitoring, and detection and management of complications.

Materials And Methods: The Pan American Crohn's and Colitis Organization (PANCCO) and the Inter-American Society of Endoscopy (SIED) appointed 22 Latin American experts in IBD to develop a consensus study using the modified Delphi method, based on the best available evidence. A working group of 22 members from 9 countries identified 15 topics and formulated 98 statements, who participated in 2 rounds of voting.

[Recommendations based on the management of patients with Crohn disease in the Peruvian context. Position paper of the Association for the Study of the Intestine (ASPEIN)].

Crohn's disease is a chronic inflammatory disease of the gastrointestinal tract whose etiology is unknown, which can transmurally affect any segment of the intestine and/or the perineal region. Worldwide, the incidence of inflammatory bowel disease has increased in recent decades, and the same upward trend can be seen in South America. At national level, there are no official data, however, the increase in the number of publications in the last 20 years confirms this upward trend.

[Gastrointestinal hemorrhage as an uncommon form of presentation of primary intestinal amyloidosis: case report].

Intestinal amyloidosis is a rare and underdiagnosed systemic disease, which is characterized by the extracellular deposition of proteins that are grouped into amyloid fibers. This entity is rare and is usually a form of presentation in the context of systemic amyloidosis, the diagnosis of which is based on the presence of amyloid in histology. The clinic is usually non-specific; chronic diarrhea, weight loss, abdominal pain and bloating; Gastrointestinal bleeding is a very rare manifestation.

[Inflammatory Bowel Disease in elderly patients: Clinical characteristics and management in a tertiary hospital].

Inflammatory bowel disease (IBD) in elderly patients is characterized by its clinical variability, different differential diagnoses and therapeutic management. The objective of our investigation is to evaluate the clinical characteristics and management of elderly patients with IBD. We developed an observational, descriptive, retrospective study from January 2011 to December 2019 in patients with IBD at the Gastroenterology Service of Guillermo Almenara Irigoyen National Hospital, Lima-Peru.

[Medical and surgical management of moderate-to-severe inflamatory bowel disease].

Unlabelled: The management of inflammatory bowel disease (IBD) is mainly medical, however, more than 70% of patients with Crohn's disease (CD) and 25% with ulcerative colitis (UC) will require surgery during their lifetime.

Objective: To evaluate medical, surgical management and evolution in patients with moderate-to-severe IBD.

Materials And Methods: Observational, descriptive, retrospective study from January 2011 to December 2019 in the Gastroenterology Service of the Guillermo Almenara Irigoyen National Hospital, Lima-Peru.

[Clinical significance of the presence of granulomas in Crohn's disease].

Unlabelled: Epithelioid granuloma is a characteristic histological feature of Crohn's disease (CD), but their significance with respect to the severity and progression of the disease is still uncertain.

Objective: To evaluate the clinical characteristics of CD patients in relation to the presence or not of granulomas in histological findings.

Materials And Methods: An observational, descriptive, retrospective study in patients diagnosed with CD from January 2004 to December 2019 in the gastroenterology department of the Guillermo Almenara Irigoyen National Hospital, Lima-Peru.

[Clinical-pathological characteristics and endoscopic management of colonic sessile serrated lesions in a reference hospital in Lima - Peru].

Unlabelled: Colorectal cancer (CRC) is one of the most frequent worldwide. Approximately one third of cases originate from the serrated pathway of carcinogenesis, with colonic sessile serrated lesions (SSL) being the main cause of interval CRC.

Objective: To evaluate the clinical, endoscopic, histological characteristics and endoscopic management of colonic LSS.

[Loss of response to anti-TNF therapy in inflammatory bowel disease: experience in a reference hospital in Lima - Peru].

Objective: To evaluate the response to treatment with anti-TNFs in patients with inflammatory bowel disease.

Materials And Methods: Prospective observational study conducted in the Gastroenterology service of the Guillermo Almenara National Hospital, from January 2015 to August 2018.

Results: 31 patients with inflammatory bowel disease who received maintenance therapy with Infliximab were evaluated.

[Evaluation of endoscopic and histological activity as predictors of clinical relapse in ulcerative colitis].

Unlabelled: Ulcerative colitis is a chronic inflammatory disease characterized by a recurrent and remitting course. Clinical remission and mucosal healing are the current therapeutic goals in management. The histological remission could be a better objective because of its prognostic impact.
