Abstract Background and study aims Diminutive colorectal polyps are increasingly being detected and it is not clear whether jumbo biopsy forceps (JBF) has comparable efficacy to that of cold snare polypectomy (CSP) for management of these lesions. Methods An electronic literature search was performed for studies comparing resection rates of JBF and CSP for diminutive polyps (≤ 5 mm). The primary outcome was incomplete resection rate (IRR). Secondary outcomes included failure of tissue retrieval and complication rates (post-polypectomy bleeding, perforation etc.). Leave-one-out analysis was performed to examine the disproportionate role of any of the studies. Meta-analysis outcomes and heterogeneity (I2) were computed using Comprehensive meta-analysis software. Results A total of 4 studies (3 randomized controlled trials and 1 retrospective study) with 407 patients and 569 total polyps (mean size of 3.62 mm) was included for analysis. IRR of JBF was slightly higher than that of CSP (10.2 % vs 7.2 %) but this was not statistically significantly different (Pooled OR 1.76; 95 % CI 0.94–3.28; I2 = 0). Leave-one-out analysis showed no significant difference in the pooled OR comparison either. Two of the 4 studies reported 0 % failure of tissue retrieval for JBF and 1 % and 4.3 % for CSP. There were no complications for either group from the 2 studies that reported this outcome. The quality of the included studies was moderate to high. Conclusions This systematic review with only limited data shows that JBF and CSP are not statistically different in completely removing diminutive polyps, although careful endoscopic assessment is needed to ensure complete removal of all polyp tissue.

Guidelines from national and international professional societies on upper gastrointestinal bleeding highlight the important clinical issues but do not always identify specific management strategies pertaining to individual patients. Optimal treatment should consider the personal needs of an individual patient and the pertinent resources and experience available at the point of care. This article integrates international guidelines and consensus into three stages of management: pre-endoscopic assessment and treatment, endoscopic evaluation and haemostasis and postendoscopic management. We emphasise the need for personalised management strategies based on patient characteristics, nature of bleeding lesions and the clinical setting including available resources.

Introduction: Pre-operative endoscopic assessment of the distal extension of hypopharyngeal cancer is essential for proper surgical extirpation. This assessment is frequently not feasible in advanced, obstructing tumours.Aims: To study the role of a proposed new diagnostic technique: intra-operative open oesophagoscopy, in distal assessment of advanced hypopharyngeal cancer.Materials and methods: A clinicopathological study, including 35 consecutive patients with obstructing hypopharyngeal cancer.Results: Intra-operative open oesophagoscopy revealed inferior submucosal tumour extension in 19 out of 22 cases proven histopathologically, with a sensitivity, specificity and accuracy of 86, 100 and 91 per cent, respectively. Oesophageal skip lesions were detected in two cases. Intra-operative open oesophagoscopy findings surpassed data obtained from pre-operative radiological investigations and influenced the extent of resection performed. Accordingly, 19 patients had a total laryngopharyngectomy for local disease control, while 16 patients needed an additional total oesophagectomy. Histopathologically negative inferior resection margins were obtained in all cases.Conclusions: Intra-operative open oesophagoscopy was found to be a reliable diagnostic modality for distal assessment of obstructing hypopharyngeal cancer in cases in which pre-operative distal endoscopic examination was not feasible.

Objectives The goal of our study was to determine whether visual assessment of the esophagus and stomach could predict abnormal histology and determine the frequency of interventions based on biopsies in patients undergoing endoscopy for elevated tissue transglutaminase immunoglobulin A antibody (TTG). Methods Pathology records were searched for patients with biopsy performed for elevated TTG. Pathology report, endoscopy report, and follow-up were obtained and slides from the duodenum reviewed. Pathology was considered gold standard for sensitivity and specificity calculations. Results 240 patients were included. 215 patients had esophageal biopsies performed. Esophageal endoscopic visual assessment had sensitivity of 47% and specificity of 93% for abnormal histology. 16(7%) patients had therapy or referral related to results and, of these, 6(38%) had visually normal endoscopy. 237 biopsies were performed of stomach. Gastric endoscopic visual assessment had a sensitivity and specificity of 20% and 87%. 24(10%) patients had therapy based on findings and, of these, 12 (50%) had visually normal endoscopy. Conclusions Endoscopic assessment of esophagus and stomach has low sensitivity and high specificity for pathologic abnormalities when indication for endoscopy is elevated TTG. When endoscopy is visually normal clinical interventions based on biopsy are rare, and foregoing biopsy may be considered.

Perianal Crohn's Disease

AbstractThe incidence of Crohn's disease is increasing worldwide. The clinical course of childhood onset Crohn's disease is particularly aggressive with characteristic disease localization in the ileocecal region and colon, often associated with perianal disease. Severe complications of perianal disease include recurrent perianal sepsis, chronic fistulae, fecal incontinence, and rectal strictures that impair quality of life and may require fecal diversion. Care of patients with perianal Crohn's disease requires a multidisciplinary approach with systematic clinical evaluation, endoscopic assessment, and imaging studies followed by combined medical and surgical management. In this review, we provide an update of the epidemiology, pathophysiology, diagnostics, and management of perianal Crohn's disease in children and adolescents.
