CPT® Code 43810

The procedure described by CPT® Code 43810, known as gastroduodenostomy, is a surgical intervention that establishes a connection between the stomach and the duodenum without the need to remove any part of either organ. This approach is particularly significant as it allows for the restoration of gastrointestinal continuity while preserving the anatomical structures involved. During the procedure, the surgeon makes a midline incision in the abdomen to gain access to the stomach and duodenum. Once exposed, any adhesions that may be present are carefully lysed, allowing for better mobility of the organs. An incision is typically made along the greater curvature of the stomach, and the stomach is then divided at the gastroduodenal junction. The opening in the stomach is subsequently closed with sutures. Following this, the duodenum is sutured to the stomach in an end-to-side manner, which facilitates the passage of digestive contents from the stomach into the duodenum. Alternatively, the duodenum may be rotated to align with the stomach, allowing for a side-to-side connection. This method involves longitudinal incisions in both the stomach and duodenum, which are then sutured together. After the connection is established, the surgical site is irrigated, and drains may be placed as necessary to prevent fluid accumulation. Finally, the abdominal incision is closed in layers to ensure proper healing. This procedure is essential for patients requiring surgical intervention to address various gastrointestinal conditions while maintaining the integrity of the digestive tract.
