OBJECTIVE: Indocyanine green has been used in the assessment of the gastric conduit perfusion in thoracoscopic esophagectomy to prevent malperfusion-associated anastomotic leak. This study aims to evaluate the initial results of investigating the gastric conduit perfusion with indocyanine green in the surgical treatment of esophageal cancer.
PATIENTS AND METHODS: This cross-sectional descriptive study was carried out on 54 esophageal cancer patients undergoing thoracoscopic esophagectomy and gastric conduit reconstruction. The blood flow in the gastric conduit was observed using an infrared camera and indocyanine green after completion of the conduit and after tunneling the conduit through the mediastinum to the neck.
RESULTS: The gastric conduit width and length were 5.2 ± 0.3 cm, and 31.5 ± 1.6 cm, respectively. The length of the gastric conduit from the junction between the right and left gastroepiploic to the point where the distal end of the gastric conduit still has a vascular pulse was 11.9 ± 4.3 cm. Seventeen patients (31.5%) had poor blood supply at the distal end of the gastric conduit, with indocyanine green appearance time ⩾ 60 s, in whom anastomotic leaks occurred in five patients (9.3%). The lack of connection between the right and left gastroepiploic vessels was associated with poor blood supply of the distal gastric conduit (p = 0.04). Multivariable logistic regression analysis showed association between the time of indocyanine green appearance at the distal gastric conduit and the risk of anastomotic leak (OR = 1.99, 95% CI = 1.10-3.60, p = 0.02).
CONCLUSION: Investigation of gastric conduit perfusion using indocyanine green in gastric conduit reconstruction detected 31.5% of patients with poor blood supply at the distal end of the conduit, in whom 9.3% had anastomotic leak. The longer indocyanine green appearance time in the distal gastric conduit (segment BC), was associated with the higher rate of the anastomotic leak.
