Abstract Background and study aims Linked color imaging (LCI) is a new image-enhancing technique that facilitates the differentiation of slight differences in mucosal color tone. We performed an exploratory analysis to evaluate the diagnostic capability of LCI in ultraslim endoscopy, using data from patients examined in the LCI-Further Improving Neoplasm Detection in upper gastrointestinal (LCI-FIND) trial, a large-scale, multicenter, randomized controlled trial that demonstrated the capability of LCI for detecting neoplastic lesions in the upper gastrointestinal tract. Patients and methods Data from the LCI-FIND prospective trial were used. In the LCI-FIND trial, 1502 patients with a history of gastrointestinal cancer were randomly assigned to two groups based on examination methods: white light imaging (WLI) followed by LCI (WLI group) and LCI followed by WLI (LCI group). The present exploratory analysis investigated the outcomes of patients who underwent ultraslim and standard endoscopies. Results Ultraslim endoscopes were used in 223 patients and standard endoscopes in 1279 patients. The primary endpoint of the LCI-FIND trial was the percentage of patients diagnosed with a neoplastic lesion using WLI or LCI. The corresponding percentage tended to be higher with LCI than with WLI among patients who underwent ultraslim endoscopy and among those who underwent standard endoscopy; the crude risk ratio was 2.21 [95 % confidence interval (CI): 1.06–4.67], and the adjusted odds ratio was 2.46 (95 % CI: 1.07–5.63). Conclusions Our exploratory analysis of data from the LCI-FIND trial showed that LCI is useful in identifying neoplastic lesions, when used in ultraslim endoscopy.

Background: Diseases of gastrointestinal tract are a major cause of morbidity and mortality. Objective: This study was carried out to determine the spectrum of histopathological lesions of upper gastrointestinal tract. Methodology: This retrospective study was conducted in the Department of Pathology at North East Medical College, Sylhet, Bangladesh during a 36 months period from January 2013 to December 2015. Endoscopies were performed using Olympus 150, forward viewing upper GI endoscope. The biopsy specimens received were fixed in 10.0% formalin and routinely processed in Haematoxyline & Eosin stain. Results: The present study included 135 endoscopic biopsies. The mean age with SD of the study population was 53.20±16.09 years. Among 53 cases of esophageal biopsies 8(15.08%) cases showed non-neoplastic lesions and 45(84.92%) cases were neoplastic of which 39(73.6%) cases and 6(11.32%) cases were squamous cell carcinoma and adenocarcinoma respectively. Among 6 cases of gastro esophageal junction biopsies 3(50%) cases showed non-neoplastic lesions and 3(50%) were neoplastic, of which 2(33.33%) were adenocarcinoma and 1(16.67%) were squamous cell carcinoma. Among 61 cases of stomach biopsies 34(55.74%) showed non-neoplastic lesions and 27(44.26%) were neoplastic, of which 1(1.64%) case was adenoma and 25(40.98%) were adenocarcinoma. Among 15 cases of duodenal biopsies 13(86.67%) cases showed non-neoplastic lesions and 2(13.33%) were neoplastic one of which was adenocarcinoma (6.67%). Among 135 cases endoscopist reported 82(60.74%) cases as neoplastic and 53(39.26%) as non-neoplastic, whereas histopathology revealed 77(57.03%) cases neoplastic and 58(42.97%) cases non-neoplastic. Conclusion: Common site of upper GIT endoscopic biopsy is stomach which are mostly neoplastic lesion; however, most common malignancy is squamous cell carcinoma of the oesophagus.

Flexible endoscopy of the upper gastrointestinal tract usually does not form part of the primary diagnostic evaluation of the globus syndrome. In a prospective trial, a flexible endoscopy was performed in 51 globus patients with normal results of the laryngologic and radiographic examination. Pathologic findings requiring therapy were diagnosed in 70.6 per cent of cases. The most frequent findings were reflux oesophagitis (n = 24; 47 per cent) and hiatial hernia (n = 25; 49 per cent). In 16 cases (31,4 per cent) these were accompanied by other pathologic lesions. A total of 32 patients (62.7 per cent) suffered from oesophageal diseases as sole aetiologic factors of the globus syndrome, which led us to postulate a causative relationship in these cases. Flexible endoscopy therefore can contribute significantly to the differential diagnosis of the globus syndrome. It must be kept in mind, however, that there is a ‘blind zone’ for endoscopic assessment in a region of the hypopharynx, thus some indications may require rigid endoscopy.

Introduction: The Upper Gastrointestinal Tract (UGIT) disorders are quite common in routine clinical practice and have high degree of morbidity and mortality. They can be studied by collecting tissue sample by way of fiberoptic endoscope and by subjecting the tissue to histopathological examination. Aim: To study the spectrum of histopathological lesions of UGIT lesions by endoscopy. Materials and Methods: This was a prospective observational study done in the Department of Pathology at PSIMS, Chinna Avutapalli, Andhra Pradesh, India, over a period of one year from March 2019 to February 2020 on 160 endoscopic biopsies. All UGIT endoscopic biopsies received were examined histopathologically. The data was entered into excel sheets and percentages and ratios were calculated. Results: Lesions of UGIT were more common in the age groups of 31 to 50 years and the male to female ratio was 1.9:1. The patient age ranged from 20 years to 78 years. Stomach was the common site for UGIT endoscopic biopsies i.e., 80 (50%) followed by oesophagus 50 (31.2%) and then duodenum 30 (18.7%). At all three sites, non-neoplastic lesions predominated over neoplastic lesions. The gastric malignancies were more common in antral and pyloric regions. Conclusion: Males in the fourth and fifth decades are more prone for UGIT lesions with predominance of chronic non-specific inflammatory conditions as compared to neoplastic conditions. Malignancy within the stomach, more commonly affects the antrum and pylorus. Malignant lesions are very rare in duodenum.
