Objectives: To evaluate and compare ectasia and pseudoectasia in post-myopic LASIK patients presenting with corneal topographic changes indicative of ectasia using the Ectasia Risk Factor Score System (ERFSS). Methods: Single-center retrospective comparative case series of a consecutive chart review of cases in 18 years who underwent bilateral myopic-LASIK and showed topographic changes indicative of ectasia. Results: Four patients were included. Group 1: pseudoectasia eyes, consisting of two patients with bilateral pseudoectasia, and Group 2: ectasia eyes, consisting of two patients with unilateral ectasia. The clinical course of the cases was discussed and compared based on the ERFSS parameters: topography pattern, residual stromal bed thickness, age, preop thinnest cornea, and pre-operative spherical equivalent (SE) manifest refraction (MR). Group 1 scored zero to low risk for developing ectasia while Group 2-eyes with ectasia scored moderate risk. The predictive value of the ERFSS was 1 in this study. Conclusion The ERFSS is a good measure in deciding the suited treatment plan for patient undergoing refractive procedure. Knowing the clinical course of ectasia and pseudoectasia is helpful in the therapeutic approach since pseudoectasia is reversible when identified and managed early as seen in this study.

Rectal stricture is an occasional complication of abdominoperineal pull-through and low anterior resection of the rectum and irradiation injury. Although the causes and pathogenesis of this phenomenon are poorly understood, various techniques for stricture dilatation have been described. In this article, we present two cases of severe postoperative rectal stricture that were not amenable to conventional methods of dilation but were succesfully managed by transanal electroresection using endoscopic transurethral electroreectoscope.

Fairly specific and important duodenoscopic findings for diagnosing mucinous ductal ectasia (MDE) of pancreas include a prominant ampulla, patulous ampullary orifice and extrusion of mucin through the ampulla. However, we have experienced two cases of mucinous ductal ectasia without these pathognomonic appearance of ampulla. Initially, two cases were admitted for evaluation of pancreatic multicystic lesions, and MDE was incidentally found. Their pancreatographic findings showed normal main duct and cystic dilatation confined to the branch ducts. On gross findings of surgical specimens, a duct dilatation with gelatinous mucin was localized at the uncinate process of the pancreas. Microscopically, the ductal epithelia containing mucin were lined with well-differentiated tall columnar cells showing focal hyperplastic change. We report these unusual cases of MDE with review of the literatures.

To objectively assess the difficulty in the procedures of corrosive esophageal strictures, the success rates, the number of sessions and balloon dilatation and complications were evaluated in 66 patients with esophageal strictures who underwent balloon dilatation. These patients were grouped into three according to the causes as corrosive esophageal strictures (n=24), non-corrosive benign strictures (n=22) and malignant strictures (n=22). Success rates were 29% in corrosive esophageal strictures, 86% in noncorrosive benign strictures, and 85% in malignant strictures. Required average number of sessions and balloon dilations were 3.4 and 7.4 in corrosive strictures and 1.4 and 2 in noncorrosive benign and malignant strictures, respectively. Esophageal rupture occured in 33% of corrosive strictures, 4% of each noncorrosive benign and malignant strictures. Pain in corrosive esophageal strictures was severest. In conclusion, balloon dilatation in corrosive strictures has low success rate and high complication rate and requires more frequent dilation, which implies that it is more difficult than other strictures.
