These attachments can limit how far the fundus moves toward the esophagus or gastroesophageal junction. Releasing them reduces tethering and increases the stomach’s flexibility, which is important when the fundus must be repositioned. The extent of release must be balanced with preservation of an adequate blood supply and careful control of bleeding during dissection.
They provide the blood supply that supports fundus viability after surrounding attachments are released. Preserving these vessels helps maintain healthy tissue for subsequent repositioning, fundoplication, or reconstruction. Injury or inadequate preservation can undermine tissue viability and functional results, so vascular awareness remains central even when the goal is to increase mobility.
By increasing the fundus’s reach and flexibility, mobilization allows the tissue to be positioned around the gastroesophageal junction without excessive tension. This positioning is important because the operation depends on using the fundus in a controlled, functional configuration. Adequate release therefore contributes to the intended surgical arrangement rather than simply creating additional movement.
Careful dissection balances two competing needs: releasing attachments sufficiently for useful movement while avoiding unnecessary bleeding and loss of tissue viability. The technique therefore depends on controlled separation of the fundus from surrounding structures, with attention to the vessels that must remain functional. This balance supports safer repositioning and more reliable operative results.
The procedure begins by exposing the upper stomach and identifying the attachments that restrict fundus movement. Surgeons then release the fundus from structures such as the gastrosplenic ligament and short gastric vessels while preserving the gastric and gastroepiploic blood supply. After dissection, the fundus can be repositioned for the planned esophageal or gastroesophageal junction operation.
Gastric Fundus Mobilization is relevant when an operation requires the fundus to reach or surround the gastroesophageal junction. Its applications include creating a fundoplication for gastroesophageal reflux disease, supporting hiatal hernia repair, and providing stomach tissue for selected esophageal reconstructive procedures. The same principles help adapt the stomach to different operative requirements.
