Background
Minimally invasive esophagectomy (MIO) is now established as a valid alternative to open surgery for the management of esophagogastric
cancers. However, a high incidence of ischemia-related gastric conduit failure (ICF) is observed, which is detrimental to
any potential benefits of this approach.
Methods
Since April 2004, MIO has been the procedure of choice for esophagogastric resection in the authors’ unit. Data relating to
the surgical technique were collected, with a focus on ischemic conditioning by laparoscopic ligation of the left gastric
artery (LIC) 2 weeks or 5 days before resection.
Results
A total of 97 patients underwent a planned MIO. Four in-patient deaths (4.1%) occurred, none of which were conduit related,
and overall, 20 patients experienced ICF (20.6%). In four patients, ICF was recognized and dealt with at the initial surgery.
The remaining 16 patients experienced this complication postoperatively, with 9 (9.3%) of them requiring further surgery.
Of the 97 patients, 55 did not undergo ischemic conditioning, and conduit failure was observed in 11 (20%). Thirty-five patients
had LIC at 2 weeks, and 2 (5.7%) experienced ICF. All seven patients (100%) who had LIC at 5 days experienced ICF. Timing
of ischemic conditioning (p < 0.0001) had a definite impact on the conduit failure rate, and the benefit of ischemic conditioning at 2 weeks compared
with no conditioning neared significance (p = 0.07).
Conclusions
Ischemic failure of the gastric conduit significantly impairs recovery after MIO. Ischemic conditioning 2 weeks before surgery
may reduce this complication and allow the benefits of this approach to be realized.
