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 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 (AL) is a serious complication after esophagectomy. The retrosternal (RS) route has been selected majorly to reduce reflux and related pneumonia and considering mediastinal recurrences. AL has been developed more in RS than posterior mediastinal (PM) route reconstruction. Therefore, we suspected the sterno-tracheal distance (STD) might be related to AL and started the selection according to the STD from 2009. Methods A total of 221 patients who underwent a subtotal esophagectomy with gastric tube reconstruction during January 2004—April 2017 were investigated. The patients were classified into the 'after STD selection' (A; n = 144) group and the 'before STD selection' (B, n = 77) group. The incidences of and the risk factors for AL between the two groups were compared. Results The incidence of AL was high in the B group (18.2%), and 78.6% of the patients who developed AL were treated with RS route. The median STDs of the patients with AL and no AL were 10.3 mm and 14.5 mm, respectively (p = 0.001). These results demonstrated that the STD was a risk factor for AL in the RS route. Based on these results, 13 mm was set as the cutoff value. After STD selection, the median STD increased from 14.0 mm to 17.3 mm (p = 0.001), and the incidence of AL decreased significantly from 26.2% to 11.1% in the RS route (p = 0.037). Conclusion The STD was the independent risk factor for AL in the RS route. RS route reconstruction should be avoided for the patients with STD &lt;13 mm.

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.

Abstract Background For patients with locally advanced esophageal cancer, radical esophageal resection with gastric tube reconstruction preceded by chemo(radio)therapy offers the best chance for cure. Anastomotic leakage (AL) is one of the most severe complications following esophageal surgery, leading to significant morbidity, prolonged hospital stay, considerable costs, decreased quality of life and increased mortality. Management is complicated and not standardized. The objective is to gain insight into the different opinions on AL management among upper gastrointestinal surgeons and to verify the need for a diagnostic and treatment guideline. Methods Surgeons with particular interest in esophageal surgery, were invited to participate in an online questionnaire. The survey consisted of questions pertaining to the surgeons’ experience, operation characteristics, management routine and their opinion on international guidelines on the diagnosis and therapy of AL. Results Of the 331 invited physicians, 40% participated in the survey. 90.7% Use laboratory diagnostics and 62.8% imaging and/or endoscopy postoperatively on routine basis. In case of suspected AL, the first choice of diagnostic imaging modalities was mostly a CT scan (35.7%) or a dynamic swallow investigation (33.3%). In case of AL, indepently of the clincal manifestations (local symptoms only, medianstinal manifestations or In case of gastric conduit necrosis) the treatment strategies differed widely between surgeons (table 1). Over 70% of the responders agree that there is a need for a solid international guideline on AL management. Conclusion There is no general consensus in the management of AL. There is a need for an international guideline regarding the optimal management of AL. Disclosure All authors have declared no conflicts of interest.

Abstract Description Anastomotic leakage is one of the most severe complications after esophageal resection with gastric tube reconstruction. Impaired perfusion of the gastric fundus is seen as the main contributing factor for this complication. Transection of the left gastric and gastro-epiploic artery and veins results in compromised perfusion in the fundus area which can result in anastomotic dehiscence (5–20%), relating to high morbidity and mortality (3–4%). The main objective of this observational study is to evaluation gastric tube microcirculation with Sidestream Darkfield Microscopy (SDF). Method This study included 22 patients (October 2015 - June 2016). Intra-operative microscopic images of gastric tube microcirculation were obtained with SDF directly after reconstruction. Using software (AVA2.0), the following parameters were evaluated: average velocity (μm/sec), Microvascular Flow Index (MFI), Total Vessel Density (TVD), Perfusion Vessel Density (PVD), Proportion of Perfused Vessels (PPV) and the De Backer Score (DBS), to assess change in perfusion. Results SDF accurately visualized and evaluated microcirculation in all patients. A SDF-stabilizer was used to create stable images. The average velocity decreased significantly towards the fundus (P = 0.001). Also, MFI, PVD and PPV were significantly lower towards the fundus, compared to the base of the gastric tube (P = 0.0002). No differences in TVD and DBS were observed, which was associated to the observed vessel dilation in the fundus-area. This vessel dilation proposes that compromised venous return may play an important role in the development of necrosis and leakage. Three patients developed anastomotic leakage. Conclusion This is the first study presenting quantitative microcirculation imaging with SDF of the gastric tube. Velocity, MFI, TVD and PPV were accurate parameters to observe change in perfusion after reconstruction. Also, vessel dilation in the fundus suggests a role for venous return in the development of ischemia. Quantitative microcirculation with SDF could allow for intra-operative early risk stratification, and, potentially, can result in a reduction of anastomotic leakage.

Abstract Background In esophageal reconstruction, the gastric tube (GT) is superior in elevation and handiness of the maneuver; therefore, GT is most often selected as a reconstruction conduit. Although some leakages from esophagogastric anastomoses are induced by ischemic or congested peripheral blood flow in the reconstruction conduits, the association between the GT and the incidence of anastomotic leakage (AL) is unclear. Methods Between February 2013 and September 2017, 188 consecutive patients who underwent an esophagectomy with GT reconstruction were enrolled in this cohort study. We performed GT reconstructions using narrow gastric tubes (Gr.N) until May 2016, which is when we began preparing and using stretched GTs (Gr.S). We retrospectively evaluated the incidence of AL. Results AL occurred in 29 of 188 (15.4%) patients, and the frequency of AL occurrence in Gr.S was lower than that in Gr.N (P = 0.034). Sex, body mass index, Brinkman index, and presence of hypertension or anemia were significantly associated with AL (P = 0.033, 0.041, 0.003, 0.030, and 0.042, respectively). The multivariate logistic regression analysis suggested that the type of GT used and the Brinkman index were independent risk factors for AL (P = 0.016 and 0.020, respectively). Conclusion Our results demonstrated that the difference in the GT preparation method was an independent risk factor for AL after cervical esophagogastrostomy. We suggest that the method of GT preparation could contribute to a reduction of AL after esophagectomy. Disclosure All authors have declared no conflicts of interest.
