Modified Thoracoscopic versus Minimally Invasive Oesophagectomy in Curative Resection of Oesophageal Cancer

Abstract

Conventional thoracoscopic oesophagectomy is time-consuming and requires sophisticated endoscopic skills. To reduce these problems we have modified the operating procedure, first by anastomosis of the oesophagus with the tubular stomach pulled up via the retrosternal route, followed by thoracoscopic oesophagectomy (modified thoracoscopic oesophagectomy). Outcomes were compared between the modified procedure and minimally invasive oesophagectomy. There were no significant differences in general preoperative clinical characteristics between the two patient groups. The modified thoracoscopic oesophagectomy group had significantly lower hospitalization expenses, significantly shorter operation times and significantly more lymph nodes removed compared with the minimally invasive oesophagectomy group, but there were no significant group differences in lengths of hospital and intensive care unit stays, morbidity and mortality. These results indicate that modified thoracoscopic oesophagectomy is feasible, simplifies operating procedures and reduces hospitalization expenses with acceptable morbidity.
