Abstract

Introduction: Morbidity associated with anastomotic leak after oesophagectomy is significant. Techniques to reduce this risk include ischaemic conditioning of the gastric conduit prior to oesophagectomy.

Aim: To quantify the rate of anastomotic leak after a hybrid minimally invasive McKeown oesophagectomy preceded by laparoscopic gastric devascularization (LGD).

Material and methods: We identified patients who had undergone neoadjuvant chemoradiotherapy followed by LGD and McKeown oesophagectomy and conducted a retrospective case series. The primary outcome was anastomotic leak, and secondary outcomes included common post-operative complications within 30 days.

Results: Eleven patients were identified. Seventy-three per cent were male, and 7 of 11 patients were age 70+ years. 91% of tumours were located in the lower oesophagus or gastroesophageal junction (GEJ), and 72% of the series had clinical stage of II-III. The median ischaemic conditioning time was 15 days. Eighteen per cent of patients developed an anastomotic leak, and all were managed non-operatively. One patient developed an anastomotic stricture. Three patients developed pneumonia. Three patients suffered wound infection at the site of the neck incision. One had respiratory failure requiring ventilator support. None required reoperation or readmission. There were no mortalities following either operation.

Conclusions: Laparoscopic ischaemic conditioning via LGD prior to a hybrid McKeown oesophagectomy for malignancy was associated with a leak rate similar to previously published data for a McKeown oesophagectomy without prior LGD.
