Minimally invasive oesophagectomy: a valuable alternative to open oesophagectomy for the treatment of early oesophageal and gastro-oesophageal junction carcinoma

The aim was to conduct a comparative analysis of outcome after minimally invasive oesophagectomy (MIO) versus open oesophagectomy (OO) for early oesophageal and gastro-oesophageal junction (GOJ) carcinoma.Inclusion criteria for MIO and a matched group of OO were pT<2 and N0. Surgical outcome, complications, survival and health-related quality of life (HRQL) were assessed.Between January 2005 and January 2010, 175 patients (101 OOs, 65 MIOs and nine MIOs converted to OO) fulfilled the abovementioned criteria. Histology was predominantly adenocarcinoma (75%), equally distributed between both groups as were preoperative co-morbidities (p = 0.43), pathologic staging (pT: p = 0.56) and mean number of resected lymph nodes in pTIS/1a (p = 0.23) and pT1b (p = 0.13). Blood loss was less (p = 0.01) and duration of operation longer (p = 0.001) in MIO. Hospital mortality (p = 0.66) and postoperative complications (p = 0.34) were comparable. However, respiratory complications (p = 0.008) and intensive care unit (ICU) admission (p = 0.02) were higher in OO. Gastrointestinal complications (p = 0.005), that is, gastroparesis (p = 0.004) were more frequent in MIO. At 3 months, postoperative fatigue, pain (general) and gastrointestinal pain were less in MIO (p = 0.09, 0.05 and 0.01, respectively). Five-year cancer-specific and recurrence-free survival stratified to the pathologic T-stage were not statistically different between MIO and OO.MIO is a valuable alternative to OO for the treatment of early oesophageal and GOJ carcinoma. This study underscores the need for large-scale, preferably multicentric studies to assess the real value of MIO versus OO.
