Abstract Background Postoperative anastomotic leakage is a severe complication after gastric tube reconstruction during esophagectomy. The aim of this study was to evaluate the usefulness of postoperative endoscopic assessment of anastomosis and its correlation with intraoperative indocyanine green (ICG) fluorescence assessment of the gastric tube. Methods We retrospectively reviewed 72 consecutive patients who underwent gastric tube reconstruction using the ICG fluorescence method during esophagectomy. Forty-six patients underwent the ICG line-marking method (LMM group; ICG before gastric tube creation). The other 26 underwent the conventional procedure and comprised the control group (ICG after gastric tube creation). Postoperative endoscopic assessment (PEA) of anastomosis was performed 7 days after surgery and results were classified as follows: grade 1 (normal or partial white coat), grade 2 (ulcer comprising less than half the circumference), and grade 3 (ulcer comprising more than half the circumference). Results Anastomotic leakage occurred in 7 of 72 patients (9.7%). The incidence of anastomotic leakage in the LMM group was tended to be lower than those in the control group (6.5% vs. 15.4%; P = 0.244). Of the 40 patients who underwent PEA, 3 (7.5%) had leakage. PEA grading was significantly associated with anastomotic leakage (P < 0.001). Better intraoperative ICG assessment was significantly associated with better endoscopic assessment grade (P = 0.041). Conclusion Intraoperative ICG assessment of the gastric tube was associated with PEA grading on anastomosis during esophagectomy. Disclosure All authors have declared no conflicts of interest.

Abstract Background Anastomotic leakage is one of the most frequent and severe morbidities after esophagectomy. For preventing anastomotic leakage, it is important to design a gastric tube with sufficient blood supply and to perform precise anastomosis at a well-conditioned site. We herein show our method of gastric tube reconstruction and evaluate the outcome. Methods Seven hundred and forty-six esophageal carcinoma patients who received subtotal esophagectomy with gastric tube reconstruction via the retrosternal route between 1994 and 2017 were enrolled in the present study. Although we previously used a greater curvature gastric tube with a 4 cm in diameter (narrow group), since 2000, a ‘flexible gastric tube,’ which was designed on an individual basis with the aim of preserving the vascular plexus in the center of the anterior and posterior stomach wall to the maximum possible extent in order to supply a sufficient amount of blood to the tip of the gastric tube was used (flexible group). Cervical esophagogastric end-to-side anastomosis using the circular stapler was performed during the whole period. The clinical outcomes were compared between the two groups. Results Anastomotic leakage was observed in 36 (4.8%) patients. While 24 of 155 (15.5%) patients showed anastomotic leakage in the narrow group, 12 of 591 (2.0%) patients showed anastomotic leakage in the flexible group and the clinical outcomes were significantly improved. Conclusion Our method of gastric tube reconstruction helped to improve the rate of anastomotic leakage after esophagectomy. At present, we are investigating the status of the blood flow using an ICG fluorescence method and by measuring the degree of oxygen saturation and hemoglobin using a new non-invasive monitoring tool during the operation. Postoperative assessments of the anastomotic site are performed using endoscopic examinations. We herein report the results of these assessments.

Abstract Description One of the most frequent complication after esophagectomy is the anastomotic leakage, which is a determiming factor of morbidity and mortality after surgical treatment. The best location for the esophagogastric anastomosis (cervical or intra-thoracic) has been topic of discussion for many years, and surgical aspects as resected margins, recurrent nerve trauma and mainly the vascularization of the anastomosis. In this video we performed a cervical gastroplasty anastomosis (McKeown), side-to-side, stapled (linear stapler) with a thin gastric tube conduit, and after that we aimed to determine the feasibility and usefulness of indocyanine green (ICG) fluorescence imaging to evaluate the gastric conduit perfusion during an esophagectomy. After pulling up the gastric conduit trhought the mediastinum and after performing the cervical anastomosis, 5 mg of ICG was in jected as a bolus and visual assessment of the blood supply of the gastric conduit was seen. This patient was a 63 years old, male, with adenocarcinoma of esophago-gastric junction (Siewert II) underwent to neoadjuvant quimiotherapy (FOLFOX regimen) and submitted after 3 cycles to esophagectomy (thoracoscopy and laparoscopy). No fistula was found in post operative follow-up, and either complications. Disclosure All authors have declared no conflicts of interest.

Gastric Tube Reconstruction

Abstract Background Compromised perfusion due to ligation of arteries and veins in esophagectomy with gastric tube reconstruction often (5–20%) results in necrosis and anastomotic leakage, which relate to high morbidity and mortality (3–4%). Ephedrine is used widely in anesthesia to treat intra-operative hypotension and may improve perfusion by the increase of cardiac output (CO) and mean arterial pressure (MAP). This study tests the effect of ephedrine on perfusion of the future anastomotic site of the gastric conduit, measured by Laser Speckle Contrast Imaging (LSCI). Methods This prospective, observational, in-vivo pilot study includes 26 patients undergoing esophagectomy with gastric tube reconstruction from October 2015 to June 2016 in the Academic Medical Center (Amsterdam). Perfusion of the gastric conduit was measured with LSCI directly after reconstruction and after an increase of MAP by ephedrine 5 mg. Perfusion was quantified in flux (LSPU) in four perfusion locations, from good perfusion (base of the gastric tube) towards decreased perfusion (fundus). Intra-patient differences before and after ephedrine in terms flux were statistically tested for significance with a paired t-test. Results LSCI was feasible to image gastric microcirculation in all patients. Flux (LSPU) was significantly higher in the base of the gastric tube (791 ± 442) compared to the fundus (328 ± 187) (P < 0.001). After administration of ephedrine, flux increased significantly in the fundus (P < 0·05) measured intra-patients. Three patients developed anastomotic leakage. In these patients, the difference between measured flux in the fundus compared to the base of the gastric tube was high. Conclusion This study presents the effect of ephedrine on perfusion of the gastric tissue measured with LSCI in terms of flux (LSPU) after esophagectomy with gastric tube reconstruction. We show a small but significant difference between flux measured before and after administration of ephedrine in the future anastomotic tissue (313 ± 178 vs. 397 ± 290). We also show a significant decrease of flux towards the fundus. Disclosure All authors have declared no conflicts of interest.

Abstract Background Poor fundus perfusion is seen as the major factor for the development of anastomotic necrosis, leakage and strictures. Quantitative imaging of tissue perfusion during reconstructive surgery, therefore, may reduce the incidence of complications. Imaging the fluorescense of intravenously administered fluorophores is an optical, non-contact method to image blood flow in real-time. However, quantitative parameters for perfusion evaluation are stil lacking. The objective of this study is to test fluorescence imaging derived quantitative parameters for perfusion evaluation of the gastric tube during surgery and to correlate these parameters to patient outcome in terms of anastomotic leakage. Methods This study included 22 patients (October 2015 - June 2016). Indocyanine green (ICG) was injected intravenously and the fluorescense intensity of the gastric tube was imaged for 2–3 minutes. At 4 locations, quantitative analysis of the fluorescent intensity over time was performed to obtain perfusion related parameters: the maximal intensity, mean slope and influx timepoint. These parameters were tested for significant differences between the four perfusion areas of the gastric tube (from normal to decreased perfusion) with a repeated ANOVA test. Furthermore, these parameters and the distance of the end of the gastroepiploic artery to the fundus and distance of the demarcation of the fluorescent signal to the fundus were compared with patient outcome in terms of anastomotic leakage development. Results The fluorescent signal could be detected in all analyzed patients (n = 20). Maximal intensity, mean slope and influx timepoint were significantly different between the base of the gastric tube and the fundus (P < 0.0001). While the distance of the watershed and the demarcation of ICG to the fundus varied between patients, the distance of the demarcation of ICG to the fundus was significantly higher in the three patients who developed anastomotic leakage (P < 0.0001). No allergic reactions on ICG were witnessed. Conclusion Intra-operative fluorescence imaging is feasible to visualize perfusion quantitatively in gastric-tube surgery, using the parameters maximal intensity, mean slope and influx timepoint. A low slope and a large distance between the fluorescence demarcation and the fundus were seen in patients who developed anastomotic leakage and could therefore allow for early risk stratification of necrosis.
