Abstract:
〈 b 〉 〈 i 〉 Introduction: 〈 /i 〉 〈 /b 〉 Sufficient tissue oxygenation is essential for anastomotic healing in visceral surgery. Hyperspectral imaging (HSI) is a noncontact, noninvasive technique for clinical assessment of tissue oxygenation in real time. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 In this case series, HSI was used in 4 patients who were admitted for either esophageal cancer or cardiac carcinoma (AEG type I or II). Thoraco-abdominal surgical esophageal resection was performed after staging and neoadjuvant therapy. Intraoperative oxygenation of superficial (StO 〈 sub 〉 2 〈 /sub 〉 ) and underlying tissue (NIR perfusion index) of the gastric sleeve were studied intrathoracic by means of the TIVITA® Tissue HSI camera. This was performed prior to esophagogastric anastomosis. The postoperative course, especially in view of surgical complications, was recorded. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Assessment of StO 〈 sub 〉 2 〈 /sub 〉 and NIR perfusion index was performed in 4 regions of interest per gastric sleeve, aboral and oral of the clinically determined resection line. It allowed the fast quantification of gastric oxygenation prior gastroesophageal anastomosis. Median StO 〈 sub 〉 2 〈 /sub 〉 aboral of the determined resection line was 69%, while median StO 〈 sub 〉 2 〈 /sub 〉 in the oral part of the gastric sleeve was found at 53%. In contrast, the median NIR perfusion index was similar aboral (80) and oral (82) of the resection line. In none of the 4 studied patients, an anastomotic failure appeared. 〈 b 〉 〈 i 〉 Discussion/Conclusion: 〈 /i 〉 〈 /b 〉 This report suggests that HSI is a feasible technique for intraoperative assessment of tissue oxygenation before gastroesophageal anastomosis and might reduce the incidence of anastomotic failure in the gastrointestinal tract.
