CPT® Code 43641

The procedure described by CPT® Code 43641 involves a highly selective vagotomy, which is a surgical intervention targeting the vagus nerve, specifically its branches that innervate the stomach. The vagus nerve, known as the tenth cranial nerve, plays a crucial role in regulating various bodily functions, including the production of gastric acid. By cutting the vagus nerve, the procedure aims to reduce excessive acid secretion, thereby helping to prevent the formation of peptic ulcers. This surgical approach is particularly beneficial for patients suffering from conditions related to hypersecretion of gastric acid. The operation typically requires a midline upper abdominal incision to access the stomach and the vagus nerve. During the procedure, the surgeon identifies and dissects the vagus nerve, following it to the parietal cell branches, which are responsible for stimulating acid production in the stomach. The division of these branches is essential for achieving the desired therapeutic effect. Additionally, to address potential complications related to gastric motility and delayed gastric emptying that may arise from vagotomy, a pyloroplasty is performed. This involves enlarging the opening from the stomach to the duodenum, facilitating better gastric drainage. In some cases, a gastrostomy may also be performed, allowing for direct access to the stomach for feeding or other medical interventions. Overall, CPT® Code 43641 encompasses a complex surgical procedure aimed at managing gastric acid-related disorders through precise nerve manipulation and supportive surgical techniques.
