Background: Minimally invasive esophagectomy (MIE) is performed through various approaches, including using video-assisted thoracoscopic surgery for mediastinal esophageal dissection. The prone technique allows for gravity-aided retraction of the lung. The aim of this study was to examine perioperative outcomes after prone MIE in relation to patient preoperative comorbidities. Methods: A retrospective cohort study from our single tertiary-care center is presented. Between January 2007 and August 2010, a total of 42 patients underwent three-field prone MIE. The majority of patients were male (37 vs. 5 female), with an average age of 68 years (range = 37-87). The diagnoses for patients who underwent MIE were 35 adenocarcinoma, four Barrett's esophagus with high-grade dysplasia, two achalasia, and one squamous cell carcinoma. Neoadjuvant chemotherapy with or without radiotherapy was administered to 16 (38 %) patients. Preoperative comorbidities were quantified using the Modified Charlson Comorbidity Index; low risk was defined as a score of 0-2 (23 patients), moderate risk 3-4 (14 patients), and high risk 5 or higher (five patients). Postoperative complications were stratified using the Clavien Classification Scale; minor complications were grades 1 and 2 and major complications were grades 3-5. Results: Median length of hospital stay was 8 days (range = 6-51) and median ICU stay was 2 days (range = 1-26). Average prone surgical time was 108 min (range = 67-198). Thirty-seven of 42 patients (88 %) were extubated on the day of operation. Postoperatively, all five high-risk patients had a complication, three of which were major. Eight of the 14 moderate-risk patients had a complication and three were major, and 17 of the 23 low-risk group had a complication with nine being major. There was a total of 15 major complications. Predominant complications were arrhythmias (15) and pneumonia (five), with four anastomotic leaks and two postoperative 30-day mortalities. Conclusions: This series supports using prone MIE. Despite a clinical pathway, including immediate extubation postoperatively, there is still a risk of pulmonary complications that appears to correlate with higher preoperative comorbidity scores.
