Introduction
A sphincter muscle is segmented or incised during a medical operation called a sphincterotomy. The anal sphincter and the sphincter of Oddi in the digestive system are examples of sphincters, which are circular muscles that surround openings or passages in the body. Anal sphincterotomies, the most popular kind of sphincterotomy, are utilized for managing a variety of disorders that affect the anal canal. To help alleviate discomfort brought on by anal fissures, hemorrhoids, or specific anal abscesses, a tiny incision is made in the anal sphincter muscle. Sphincterotomy reduces spasms and improves blood flow to the area by cutting the muscle, promoting faster healing and pain alleviation.
Sphincterotomies are typically carried out with the aid of specialist surgical tools or by the use of an endoscope, a flexible tube equipped with a light and camera that allows the surgeon to view the area. When carried out by a qualified medical expert, the treatment can be completed as an outpatient and is typically regarded as secure and efficient. Although there are potential risks and consequences with every surgical treatment, these should be discussed with the surgeon before having a sphincterotomy.
What Is Antithrombotic Therapy?
Antithrombotic therapy refers to the use of drugs or other treatments to stop the development of blood clots or to dissolve those that have already formed inside blood vessels. Thrombosis, or the development of blood clots, can be harmful and result in major medical disorders like heart attack, stroke, or deep vein thrombosis.
Antithrombotic therapy targets various elements of the coagulation cascade or platelet function in an effort to inhibit or lessen the clotting process. Antithrombotic agents can be divided into two categories: anticoagulants and antiplatelet medications.
-
Anticoagulants: These medications disrupt the blood coagulation process and prevent fibrin, a protein crucial to clot formation, from forming. Heparin, Warfarin, and Direct Oral Anticoagulants (DOACs) like Rivaroxaban and Apixaban are among the anticoagulants that are frequently prescribed. Deep vein thrombosis, pulmonary embolism, and atrial fibrillation are a few of the disorders for which these drugs are frequently prescribed.
-
Antiplatelet Drugs: These drugs work against platelets, which cause blood clots to develop at the site of vascular damage. Antiplatelet medications prevent platelet aggregation and lower the chance of clot development. Aspirin, Clopidogrel, and Ticagrelor are a few examples of antiplatelet medications. They are frequently recommended for ailments like acute coronary syndrome and peripheral artery disease, as well as following particular procedures or the implantation of stents.
-
The specific ailment being treated, the patient's risk factors for clotting and bleeding, and other personal considerations all play a role in the selection of antithrombotic medication. In order to achieve the ideal balance between preventing blood clots and preventing excessive bleeding, it is crucial to utilize these medications under the supervision and prescription of a healthcare practitioner.
What Are the Risks of Post-sphincterotomy Bleeding With Antithrombotic Therapy?
Antithrombotic therapy can make post-sphincterotomy bleeding more likely. According to studies, patients receiving antithrombotic therapy experience more post-procedure bleeding than those who do not. The decision to continue or stop antithrombotic therapy should be made on an individual basis based on the patient's underlying condition and the anticipated risks and benefits. However, the absolute risk still remains quite low.
A collaborative strategy combining gastroenterologists, hepatobiliary surgeons, cardiologists, or hematologists is frequently advised for treating patients on antithrombotic treatment who need sphincterotomy. The following are the risks of post-sphincterotomy bleeding with antithrombotic therapy:
-
Risk Stratification: Evaluating the patient's unique bleeding risk factors, such as the need for antithrombotic therapy, the medicine being used, and the chance for bleeding in the first place.
-
Balancing the Risk: Balancing the danger of post-sphincterotomy bleeding with the potential advantages of continued antithrombotic medication to prevent thromboembolic complications. In some circumstances, it may be thought about temporarily stopping or changing antithrombotic therapy.
-
Timing of the Procedure: Whenever possible, time the sphincterotomy to coincide with the patient's antithrombotic treatment. To reduce the impact of the medication, it could be best to do the surgery at the peak level of a once-daily anticoagulant dose.
-
Bridging Therapy: Bridging therapy may be considered in some high-risk situations where the risk of thromboembolism is judged to be severe. Bridging therapy entails temporarily replacing an oral anticoagulant with an injectable anticoagulant (such as low molecular weight heparin) during the perioperative period.
-
Local Hemostatic Measures: Different strategies may be utilized by endoscopists to lessen the chance of bleeding during and after sphincterotomy. These could involve using cautery, using clips, or, if required, injecting epinephrine directly into the bleeding area.
What Is the Management of the Post-sphincterotomy Bleeding With Antithrombotic Therapy?
-
Consider the patient's comorbidities, medical history, and bleeding risk factors. Age, a history of gastrointestinal bleeding, coagulopathy (a hemostasis problem that causes either excessive bleeding or clotting), thrombocytopenia (a disorder that develops when the level of platelets is inadequate), liver illness and renal failure are a few things to take into account.
-
Consider the cause of the patient's antithrombotic therapy (for instance, antiplatelet medications or anticoagulants) and decide if it is necessary or advantageous to continue or discontinue the treatment.
-
Consider the unique qualities of the patient and the necessity of the sphincterotomy. Antithrombotic therapy may need to be temporarily interrupted in some situations, while in others, the hazards of interruption may outweigh the danger of bleeding.
-
Depending on the indication, it could be possible to temporarily change the antithrombotic medication or dosage to lower the risk of bleeding without jeopardizing the patient's overall thrombotic or cardiovascular care.
-
Ensure the endoscopist doing the sphincterotomy surgery is proficient in handling potential complications. To reduce the danger of bleeding during the procedure, use cutting-edge endoscopic methods and tools, such as hemostatic clips.
-
Consider employing additional hemostatic techniques during the procedure in high-risk instances or individuals using strong antithrombotic medications. These can involve endoscopic hemostatic tools, heat coagulation, or prophylactic epinephrine injection.
-
After the sphincterotomy, constantly monitor the patient and look out for any bleeding symptoms. Clearly define the post-procedure care measures, which may include repeating the endoscopy if necessary.
The administration of antithrombotic therapy and the avoidance of post-sphincterotomy bleeding must be based on individualized assessment and a team effort comprising the patient's gastroenterologist, surgeon, and other pertinent healthcare professionals. The patient's general clinical condition, the indications for antithrombotic therapy, and the advantages and disadvantages of continuing or changing these drugs should all be considered when making decisions.
Conclusion
Anticoagulant therapy patients exhibited a more than three times higher probability of post-sphincterotomy hemorrhage, while antiplatelet therapy patients had a greater than twice elevated risk. Due to the increased risk of post-sphincterotomy bleeding, anticoagulation or antiplatelet therapy should be stopped before conducting sphincterotomy. In these patients, alternate biliary decompression methods may be employed instead. Ultimately a good and accurate medical history of the patient is required before undergoing the sphincterotomy procedure.
