[Quadruple treatment with doxycycline, furazolidone, bismuth and proton pump inhibitor is still effective against Helicobacter pylori in our population].

Our objective is to determine the effectiveness of a therapeutic regimen for helicobacter pylori that includes a proton pump inhibitor, doxycycline, furazolidone and bismuth in our location. We carried out a retrospective study, non-randomized, in a private hospital in Lima, Peru. Patients with biopsy and/or rapid urease test proven helicobacter pylori infection after an endoscopy, from January 2017 to October 2022 were included.

[Colonic malakoplakia: Rare disease that can mimic a consuntive syndrome].

Colonic malacoplakia is an unusual cause of chronic diarrhea, and it may present as a consumptive disease. At the colon, it can induce ulcerative and erosive nodular lesions, that mimic other common granulomatous or infectious diseases. Diagnosis is support in biopsies showing groups of histiocytes, with typical Michaelis-Gutmann inclusions, which are positive with the Von Kossa stain.

[Meduloblastoma and recurrent meningioma in association with colonic polyposis: an unusual presentation of Turcot syndrome].

Turcot syndrome is an association of primary neuroepithelial tumors of the central nervous system with adenomatous polyposis coli. It is a genetic disorder, with two forms; In type I, glioblastomas are usually associated with hereditary nonpolyposis colorectal cancer (HNPC or Lynch). In Type II, medulloblastomas are often associated with familial adenomatous polyposis coli (classical or attenuated).

[New simplified regimen for Helicobacter pylori eradication achieves high effectiveness. Prospective study in a private clinic in Lima, Peru].

Objective: To determine the effectiveness of two new therapeutic regimes for Helicobacter pylori versus triple therapy that includes a proton pump inhibitor, amoxicillin and clarithromycin.

Materials And Methods: prospective study, non-randomized, in a private Hospital in Lima, Peru. Patients with biopsy and/or rapid ureasa test proven Helicobacter pylori infection received one of the three therapeutic regimens and were followed with a urea breath test 1 to 6 months upon completion of therapy.

[Lower prevalence of Helicobacter pylori infection observed in patients with erosive esophagitis].

Objectives: To investigate the prevalence of helicobacter pylori infection and the histological type of gastritis in patients with erosive esophagitis and compare these findings with a control group without esophagitis.

Materials And Methods: Prospective study in the settings of a private clinic in Lima, Peru. Each esophagitis and control patient had two biopsies taken from the antrum, two from the corpus as well as two additional samples for the ureasa (CLO) test.

[Utility of the capilar pattern in the NBI diagnosis of superficial lesions of the colon: prospective validation in a private endoscopic center Lima, Peru].

Introduction: It is important to detect and remove adenomas in order to prevent colon cancer. Angiogenesis is an early change in the pre malignant transformation sequence and narrow band imaging (NBI) allows for better visualization of the capillary pattern of the mucosa.

Objective: We present our data regarding the assessment of superficial lesions of the colon on colonoscopies using NBI as well as the Sano-Emura classification.

[Advanced adenoma in 3700 colonoscopies].

Objectives: To determine the prevalence of colon polyps, distribution in the colon, as well as their histological characteristics, with special mention on advanced adenomas, in an adult population at an endoscopy center in Lima.

Material And Methods: One year long prospective study. We obtained the demographic data, reason for procedure, and endoscopic findings of each colonoscopy.

[Ischemic colitis. Presentation of three cases and review of literature].

Ischemic colitis has been associated with advanced age, cardiovascular disease, drug therapy and vascular surgery. It is an uncommon condition in the general population, but we think that not all cases are being recognized. These three patients, over 70 years old, were admitted with abdominal cramps and mild lower digestive bleeding .
