Background: Esophageal reconstruction after esophagectomy is a complex procedure with high morbidity and mortality. Anastomotic leakage is more severe and frequent in patients with preoperative comorbidities and may present with septic conditions. Considering the possibility of an easier management of such cases, we evaluated the safety and feasibility of subcutaneous esophageal reconstruction in patients with high operative risks. Methods: We performed a non-randomized retrospective observational study on the 75 (subcutaneous: 21, intrathoracic: 54) esophageal cancer patients who underwent esophageal reconstruction either through subcutaneous or intrathoracic route between January 2003 and February 2015. Preoperative data including the estimated reasons for the selection of the subcutaneous route were obtained from medical charts. Clinical outcomes were evaluated and compared between the two groups. Results: The mean postoperative hospital stay was longer in the subcutaneous group than the overall group. Anastomotic leakage occurred more frequently in the subcutaneous group [10 (47.6%) vs. 7 (13%), P=0.004]. Three major leakages resulted in chronic cutaneous fistula, but were successfully treated by lower neck reconstruction using radial forearm fasciocutaneous free flap (RFFF). There was no in-hospital mortality in the subcutaneous group. Conclusions: Subcutaneous esophageal reconstruction in high-risk patients showed a higher rate of anastomotic leakage. However, easier correction without fatal septic conditions could be obtained by primary repair or flap reconstruction resulting in lower perioperative mortality. Therefore, esophageal reconstruction through the subcutaneous route is not recommended as a routine primary option. However, in highly selected patients with unfavorable preoperative comorbidities or intraoperative findings, especially those with poor blood supply to the graft, graft hematoma or edema, or gross tumor invasion to surrounding tissues, esophageal reconstruction through the subcutaneous route may carefully be considered as an alternative to the conventional surgical techniques.
