Comparison of outcomes of open and minimally invasive esophagectomy in 183 patients with cancer
Abstract
Background and objectives: Only few randomized trials or comparative studies with large number of patients have been reported on the outcomes of thoracoscopic and laparoscopic esophagectomy (TLE) with cervical anastomosis and open 3-field esophagectomy (OE) for patients with esophageal cancer. The objective of this study is to compare the safety, feasibility, and short-term outcomes between TLE and OE (via right throax, abdomen, and left neck) for esophageal cancer.
Methods: Clinical and surgical data of patients with esophageal cancer who underwent either TLE or OE between February 2011 and December 2013 were retrospectively analyzed. Demographic characteristics, pathological data, operative procedures, and intraoperative and postoperative outcomes and survival in patients were compared between both groups.
Results: Of the 183 patients included in this retrospective analysis, 94 underwent TLE and 89 underwent OE. Demographics, pathologic data, inpatient mortality, and overall surgical morbidity in both cohorts were almost identical. A significant difference was observed in blood loss (182.6±78.3 vs. 261.4±87.2 mL, P<0.001), hospital stay (13.9±7.5 vs. 17.1±10.2 days, P=0.017), overall surgical morbidity (25.5% vs. 46.1%, P=0.004), and rate of pulmonary and cardiac complication (9.6% vs. 27.0%, P=0.002; 4.1% vs. 12.4%, P=0.046) between TLE and OE groups; however, no difference in survival period was observed between the groups.
Conclusions: The procedure of TLE for esophageal cancer possesses advantages in intraoperative and postoperative outcomes compared with OE. The TLE procedure results in similar or potentially better outcomes.
