Following OPCAB, the hemodynamics of all patients were stable, and the
gastric or colon tumor resection was successfully performed without
perioperative death. The average length of the operation was 7.47 h
(6.4-10.0 h), the average number of grafts per patient was 3.2
(2.0-5.0), the average time spent on ventilation was 13.1 h (10.1-16.5
h), and the average postoperative blood transfusion volume was 2.8 U
(2.0-4.0 U). The average length of stay in the ICU was 15.8 h (13.0-19.0
h), and the average length of the entire hospital stay was 9.4 d
(6.0-13.0 d). None of the patients had major cardiovascular events after
the operation, nor did any require an additional operation due to
bleeding or gastrointestinal fistulas. Gastrointestinal decompression
drainage in case 4 revealed brown fluid on the fourth postoperative day.
This was accompanied by melena and decreased hemoglobin, which suggested
gastrointestinal bleeding. Antiplatelet drugs were stopped, and
conservative treatment was provided. The patient improved after four
days. During the discontinuation of antiplatelet drugs, the patient did
not experience any cardiovascular symptoms such as chest tightness or
shortness of breath. Two patients (case 2 and 3) developed atrial
fibrillation after surgery, which improved with medication. Case 5
underwent colostomy surgery two months after the combined operation.
The average follow-up was 39 months (5-115 months). Two patients with
gastric cancer died at 28 months and 37 months due to tumor metastasis,
and there was no chest tightness or shortness of breath during this
period. The remaining patients were alive without cardiovascular events
or tumor progression at the end of the follow-up period (Table 5).
