Navigating Long-Term Management Challenges in Short Bowel Syndrome: A Case Report of Chronic Intestinal Failure Complicated by Kidney Dysfunction

引用

Open Journal of Internal Medicine 2024年第2期14卷 175-180页

作者： Abraamyan Feruza Prasad Thajus Salk Spencer mahmood khalid Internal Medicine Department Sutter Roseville Medical Center Roseville California USA Idaho College of Osteopathic Medicine Idaho USA

The most common cause of intestinal failure is short bowel syndrome (SBS), occurring as a result of a small functional intestine length, usually less than 200 cm, leading to intestinal malabsorption. A 59-year-old female with a past medical history of Crohns disease status post total colectomy with ileostomy over 20 years ago came to the hospital due to progressive weakness. Despite medical management, the patient had high ileostomy output, leading to electrolyte disbalance, metabolic acidosis, dehydration, and progressive kidney decline. Due to the high dependence on continuous fluid supplementation, it was decided to place a port for parenteral hydration to maintain fluid replacements and homeostasis after discharge. Prompt initiation of parenteral fluid replacement and close follow-up on patients with ileostomy and intestinal failure is strongly recommended to avoid complications and prevent intestinal, liver, or kidney transplants.

Challenges in Diagnosing and Managing Dieulafoy’s Lesions: A Case Report Highlighting the Importance of Clinical Suspicion and Multidisciplinary Approach in Obscure Gastrointestinal Bleeding

引用

Open Journal of Gastroenterology 2024年第3期14卷 80-86页

作者： Feruza Abraamyan Neeladri Misra Kenneth Tran khalid mahmood Benjamin Coombs Shilpa Lingala Sutter Roseville Medical Center Roseville USA

Upper gastrointestinal bleeding remains a significant cause of hospital admissions. Even though the incidence of peptic ulcer disease and gastritis is decreasing, the incidence rates in neoplasm, Dieulafoy’s lesions, angiodysplasia, and esophagitis are trending up, which necessities physicians to be aware of those pathologies and their specifics. Here, we represent a case of a 62-year-old male on dual antiplatelet therapy who was transferred to our hospital due to severe melena with suspicion of upper gastrointestinal bleeding. Due to hemodynamic instability, the patient was intubated and started on vasopressors. However, several repeated EGDs and CTs of the abdomen with GI bleeding protocol did not reveal the location of active bleeding to stop it. At the same time, clinically, the patient was hemodynamically unstable with continued melena. On the last EGD, a small area of concern resembling gastric varix was clipped for identification purposes, and the patient underwent a selective angiogram with further diagnosis of Dieulafoy’s lesion, which was successfully embolized. Our case demonstrates that Dieulafoy’s lesions can present as severe life-threatening hemorrhage, hard to diagnose with traditional methods such as EGD or CTs, in which case it is recommended to proceed with an angiogram sooner rather than later for further diagnosis and treatment if needed.
