Case Report: Intestinal Obstruction in a Patient on Antiplatelet Therapy
Abstract
Abstract: Background Antiplatelet therapy is commonly prescribed for various cardiovascular conditions, but it represents a unique challenge in dealing with surgical emergencies, such as intestinal obstruction. Our case is a 47-year-old patient who had a history of CABG and was on maintenance dual antiplatelet therapy, "Aspirin and Clopidogrel", attended the ER with a short history of acute abdominal pain associated with vomiting and distension. Clinical findings and imaging studiesrevealed features of intestinal obstruction.

INTRODUCTION Antiplatelet therapy is commonly used to prevent thromboembolism, especially in patients with cardiac disease. Since these medications significantly lower the risk of myocardial ischemia, they may be prescribed for long-term duration [1], which can be challenging in patients undergoing urgent surgical intervention. Intestinal Obstruction is a serious condition that may arise from various causes, including adhesions, hernia, and malignancy. In patients on antiplatelet agents, the management of intestinal obstruction may be complicated by an increased risk of bleeding, which may require careful consideration of surgical intervention [2]. This case report describes a patient on antiplatelet therapy who presented with intestinal obstruction, pointing out the challenges in diagnosis and management. By considering this case in light of the current literature, we aim to highlight the importance of recognising the interplay between antiplatelet therapy and gastrointestinal complications, ultimately contributing to improved clinical outcomes in similar patients.

Case Presentation Given the risk of bleeding complications, a multidisciplinary approach was employed. Antiplatelet was temporarily withheld, and the patient underwent an emergency laparotomy. Intraoperative findings confirmed a small bowel closed-loop obstruction due to a fibrous band, and there was an ischemic segment [3,4]. Pictures (2,3,4). Resection and primary side-to-side anastomosis were performed using an Endo GIA 60 mm. Postoperative management included careful monitoring and resumption of antiplatelet therapy on day one (aspirin 81 mg) per cardiologist’s advice [5]. B. Case Presentation A 47-year-old male who is a known case of ischemic heart disease (IHD) and (CABG) performed four years ago, presented to the Emergency Room complaining of acute abdominal pain, distension, and vomiting. His medication history includes Aspirin and Clopidogrel for CABG. On examination, the patient was vitally stable, with a distended abdomen that was diffusely tender and without bowel sounds. C. Imaging Studies i. Abdominal US Shows: Suprapubic fat oedema with distended bowel lobes, mostly the ileum, with fluid content and minimal intraperitoneal free fluid seen, is suspected of bowel obstruction. ii. Non-contrast CT Abdomen Shows: Closed loop obstruction (1). Clinical and radiological findings confirmed the diagnosis of intestinal obstruction. II. MANAGEMENT A patient with intestinal obstruction on antiplatelet therapy requires a multidisciplinary approach, careful assessment, and individualised management. Coordination among the general surgery, cardiology, haematology, ICU, and anaesthesia teams was established, and antiplatelet therapy was temporarily discontinued. After the Initial assessment, fluid resuscitation was started, a nasogastric tube was placed for decompression of the gastrointestinal tract, and vital signs were monitored closely. An exploratory laparotomy was done and revealed a fibrous band in the small bowel, causing a closed-loop obstruction. After relieving the obstruction, about 20 cm of a non-viable bowel segment was found, ''picture (4)''. Primary side-to-side anastomosis was performed with an Endo GIA 60 mm.

POSTOPERATIVE PERIOD Following the operation, the patient was shifted to the ICU for close monitoring and later transferred to the surgical ward. On day 3 postoperatively, the patient developed melena and a drop in haemoglobin [6]. An emergency upper and lower GIT endoscopy was done to look for the source of bleeding [7,8]. No source of bleeding was identified in both upper and lower gastrointestinal endoscopies. The risks and benefits of re-operative surgery were weighed against those of continued conservative management. A trial of conservative management for 48 hours was initiated, and blood transfusions of 2 bags and tranexamic acid, starting at 1 gram and increasing to a continuous dose of 500 mg, were initiated [9,10]. After 24 hours, the patient's condition improved, and melena resolved. Four days after clinical improvement, antiplatelet therapy was resumed gradually. IV. DISCUSSION This case demonstrates an intestinal obstruction in a patient receiving dual antiplatelet therapy, a standard regimen for preventing ischemic events in high-risk individuals. Managing elective surgical interventions under dual antiplatelet therapy is associated with lower mortality rates; however, acute conditions in this context present a unique challenge [11]. The primary dilemma was the decision to perform an exploratory laparotomy [12,13]. While clinical and imaging findings strongly suggested intestinal obstruction with potential complications like strangulation, perforation, and peritonitis, the risk of critical bleeding in a patient on dual antiplatelet therapy was a significant challenge. Further complicating the condition was the development of melena and a decreased haemoglobin level, indicating active bleeding. Given the high risk of mortality in the event of reoperation, we considered conservative management. This approach included blood transfusions, close vital sign monitoring, and tranexamic acid administration with a planned surgical intervention if bleeding did not improve. The patient's clinical status improved within 24 hours, and the melena resolved, supporting the decision to pursue conservative management. A.

Conservative management versus exploration was a big challenge in this patient; the decision was made to continue conservative management. After 24 hours, the patient recovered, and the melena resolved. VI. CONCLUSION This case emphasizes the need to demonstrate awareness and tailored strategies when addressing intestinal obstruction in patients on antiplatelet therapy, weighing the risks of bleeding against the benefits of surgical intervention.
