Abstract
PDF
- Congenital factor V (FV) deficiency is a rare hemorrhagic disorder that can cause excessive bleeding during and after surgery in the affected patient. This report is the case of a patient who had FV deficiency with recurrent posthemorrhoidectomy bleeding treated with the hemostatic procedure and fresh frozen plasma (FFP) transfusions. A 45-year-old male patient had previously undergone hemorrhoidectomy for multiple hemorrhoids at a local hospital. Hemorrhoidectomy was successful; however, he was transferred to our hospital for evaluation of the origin of the recurrent posthemorrhoidectomy bleeding and underwent a hemostatic procedure. This bleeding was treated with coagulation using electrocautery, multiple sutures, and FFP transfusion (1,600 mL/day) for 7 consecutive days. The patient’s plasma FV activity was 23%. Early detection of clotting factor deficiency in patients with hemorrhagic events after surgical treatments may prevent unnecessary procedures such as reoperations and minimize the cost of replacement therapy such as large-volume FFP transfusion.

Abstract
PDF
- Colonic mucosal injury is rare, but may severely fatal, complications following the administration of calcium polystyrene sulfonate resins. The incidence rate is about 0.57%, administered without sorbitol, and increases to 1.8% when it is concomitant with sorbitol, especially in postoperative patients. In this case report, we demonstrated the case of a 77-year-old female with stage 3b chronic kidney disease presented with in-hospital hematochezia after 3 weeks of calcium polystyrene sulfonate administration. The colonoscopic findings showed several serpiginous ulcers with some oozing at descending and sigmoid colon. The histological findings revealed some focal inflammation and ulcerations with crystal-like materials, compatible with cation exchange resins. The recent in vitro study, explaining the pathogenesis of cation exchange resin-associated colonic mucosal injury, was also reviewed.
