Iatrogenic Colonic Perforations: Changing the Paradigm.

Purpose: The purpose of our study was to investigate the clinical outcomes of colonoscopic perforations in patients.

Materials And Methods: We retrospectively studied patients with perforations secondary to diagnostic/therapeutic colonoscopy between 2009 and 2015 at the Pontevedra Hospital Complex. We analyzed age, closure method, length of hospitalization, and long-term progress.

Rate of adverse events of gastroduodenal snare polypectomy for non-flat polyp is low: A prospective and multicenter study.

Aim: To evaluate the rate of adverse events (AEs) during consecutive gastric and duodenal polypectomies in several Spanish centers.

Methods: Polypectomies of protruded gastric or duodenal polyps ≥ 5 mm using hot snare were prospectively included. Prophylactic measures of hemorrhage were allowed in predefined cases.

[Morbidity and mortality in pancreatic resection].

Aim: Assess the postoperative morbidity rates in pancreatic resection.

Material And Method: Prospective observational study which includes 117 patients who underwent surgery consecutively due to pancreatic or periampullary tumours. In 61 of the patients, cephalic pancreatectomy was carried out; 15 underwent total pancreatectomy; one underwent enucleation and 40 underwent distal pancreatectomy.

[Peritoneal pseudomyxoma presenting as ascites in a patient with cirrhosis].

We present the case of a cirrhotic patient with ascites and an albumin gradient of less than 1.1 g/dl. After endoscopic tests, including upper gastrointestinal endoscopic ultrasound-guided fine-needle aspiration, exploratory laparoscopy was performed to provide the diagnosis, revealing mucin throughout the peritoneal cavity and nodules on the parietal and visceral peritoneum.

EUS-guided drainage and stent placement for postoperative intra-abdominal and pelvic fluid collections in oncological surgery.

Objectives: The objective of this study was to evaluate the role and benefits of endoscopic ultrasonography (EUS) in the management of postoperative intra-abdominal fluid collections after attempted curative surgery for abdominal cancer.

Methods: The authors retrospectively analysed the Endobase from 1 July 2007 to 30 January 2011 for patients with a postoperative intra-abdominal fluid collection who had undergone EUS-guided drainage and the placement of a stent. The data analysed included the demographics, type of surgery and clinical indications of each patient as well as their clinical and radiological findings.

Extraparietal or lymphatic late relapse of neoplasms: confirmation by means of EUS-FNA key for the treatment.

Background: After treatment intended to cure systemic neoplasms, a series of monitoring strategies are followed.

Objective: To analyse our experience in confirming the cases of lymphatic or extraparietal relapse in areas accessible to endoscopic ultrasonography plus fine-needle aspiration (EUS-FNA) in long-term monitoring (>1 year of treatment for the primary neoplasm) and define what implications have been derived with regards histopathological confirmation in relation to treatment.

Materials And Methods: Retrospective analysis was made of all EUS-FNA carried out in our Endoscopy Unit during the period from 1/07/2007 to 28/02/2010 by means of searches in the Endobase (Olympus) database.

The global impact of endoscopic ultrasound (EUS) regarding the survival of a pancreatic adenocarcinoma in a tertiary hospital.

Background: Pancreatic ductal adenocarcinoma is a type of neoplasm with a high mortality rate. There are a number of different procedures that may be followed in the study of the pancreas; one such procedure is endoscopic ultrasonography (EUS).

Objective: This study aimed to retrospectively evaluate the impact on patient survival of a biliopancreatic EUS performed 2 months prior to the first treatment session of the pancreatic ductal adenocarcinoma.

[Onset of celiac disease after acute hepatitis B infection].

Celiac disease is characterized by small intestinal mucosal injury and nutrient malabsorption in genetically susceptible individuals following dietary ingestion of gluten. The pathogenesis of the disease involves interactions between environmental, genetic, and immunologic factors. Transient infections or increased permeability of the mucosa may facilitate disease onset induced by the uptake of gluten peptides into a microenvironmental milieu in the small intestinal mucosa.

Evaluation of the bilio-pancreatic region using endoscopic ultrasonography in patients referred with and without abdominal pain and CA 19-9 serum level elevation.

Context: When assessing the bilio-pancreatic region, collating the findings of serum CA 19-9 values together with findings from various imaging tests--especially endoscopic ultrasonography--is not a simple issue in daily clinical practice.

Aim: To assess the usefulness of endoscopic ultrasonography in an Endoscopic Ultrasonography Unit in two situations: patients with asymptomatic elevation of serum CA 19-9 and patients who presented with abdominal pain plus elevation of CA 19-9.

Methods: A retrospective study of those patients who underwent radial endoscopic ultrasonography between October 2004 and September 2005 in our institution, considering an elevation of CA 19-9 (equal to or greater than 37 U/mL) with or without symptoms.
