Background:
Reconstruction after esophagectomy is conventionally performed with a gastric conduit. However, in cases where a gastric conduit is unavailable, reconstructive procedures vary in terms of flap type, operative timing, and conduit route. Single-stage surgery is associated with a long operation time and high surgical stress, resulting in perioperative mortality. Recent advances in reconstructive microsurgery have made free intestinal flap transfer safe and reliable. Therefore, to overcome the shortcomings with previous methods, we performed 2-stage surgery involving free jejunum/ileum transfer for reconstruction after esophagectomy.
Patients And Methods:
From 2010 to 2018, 42 free jejunum/ileum flaps were transferred for reconstruction after esophagectomy in 41 patients. The diagnosis was esophageal cancer in 38 patients. All operations were performed in 2 stages. In most cases, total esophagectomy was performed in the first operation. The cervical stump of the esophagus was sutured to the cervical skin, creating an esophagostomy in the left neck. About 4 to 7 weeks after the first operation, the second operation was performed. The free jejunum/ileum flap was transferred through the subcutaneous route. Microvascular anastomosis was performed with the internal mammary artery and internal mammary vein, transverse cervical artery, internal and external jugular veins (internal jugular vein and EJV, respectively), and cephalic vein. The mean follow-up duration was 20 months.
Results:
Free jejunum/ileum transfer was performed as the first operation in 4 cases and as the second operation in 38 cases. A free jejunal flap was used in 36 cases and free ileal flap was used in 6 cases. The recipient arteries were the internal mammary artery in 38 cases and transverse cervical artery in 4 cases. The recipient veins were the internal mammary vein in 15 cases, cephalic vein in 13 cases, EJV in 10 cases, and internal jugular vein in 10 cases. The flaps survived in all cases, except 1 case (41/42, 97.6%). The complications were anastomotic leakage of the flap in 9 cases, respiratory complications in 10 cases, and ileus in 2 cases. Perioperative mortality was not noted.
Conclusions:
Two-stage surgery using free jejunum/ileum flap transfer is a safe and reliable option for esophageal reconstruction in cases where gastric pull-up is unavailable.
