A 33-year-old Chinese man with short bowel syndrome received intestinal rehabilitation therapy. We observed microscopically morphologic changes of remnant small intestine by magnifying endoscopy and histopathologic examination before and after 3 courses of treatment. The results revealed that the 2 methods have a fairly good correlativity, and magnifying endoscopy examination of intestinal adaptation in patients with short bowel syndrome possesses great applicative value.

Gallbladder carcinoma (GBC) is the most common malignant tumor of biliary tract, with poor prognosis due to its aggressive nature and limited therapeutic options. Early detection of GBC is a major challenge, with most GBCs being detected accidentally during cholecystectomy procedures for gallbladder stones. This letter comments on the recent article by Deqing in the , which summarized the various current methods used in early diagnosis of GBC, including endoscopic ultrasound (EUS) examination of the gallbladder for high-risk GBC patients, and the use of EUS-guided elastography, contrast-enhanced EUS, trans-papillary biopsy, natural orifice transluminal endoscopic surgery, magnifying endoscopy, choledochoscopy, and confocal laser endomicroscopy when necessary for early diagnosis of GBC.

Background: Pit pattern diagnosis using crystal violet staining for colorectal tumors is useful for qualitative and depth diagnosis. However, due to its reported carcinogenic potential, the use of crystal violet has been restricted. This study was aimed at investigating the efficacy of texture and color enhancement imaging (TXI) magnification in pit pattern diagnosis.

Background And Aim: Qualitative diagnosis of ulcerative colitis-associated neoplasia (UCAN) is crucial for surveillance colonoscopy in patients with ulcerative colitis (UC). Although the utility of magnifying endoscopy with narrow-band imaging (ME-NBI) in sporadic neoplasia diagnosis has been reported, its efficacy in UCAN remains unclear. This study aimed to evaluate the usefulness of ME-NBI for qualitative diagnosis of UCAN.

Anal canal cancer (ACC) is a rare yet noteworthy malignancy that is strongly associated with high-risk human papillomaviruses (HPVs). This case report highlights the diagnostic utility of endocytoscopy (EC) in distinguishing high-grade squamous intraepithelial lesions (HSILs) from low-grade lesions (LSILs) in a 57-year-old male presenting with hematochezia. Traditional magnifying endoscopy was inconclusive; however, EC provided detailed visualization of cellular and vascular changes, facilitating a diagnosis of HPV-associated HSIL or carcinoma in situ.

This article introduces a high-magnification electronic endoscope system that utilizes a continuous zoom optical design, enabling high-magnification imaging at the cellular level. By selecting an appropriate initial retrofocus structure, the optimized modulation transfer function (MTF) curve of the zoom objective lens approaches the diffraction limit. Additionally, the tip and operation parts of the system incorporate modular gas-tight sealing and multiple layers of protective structure.
