Background: Anastomotic leakage (AL) is one of the dreaded complications following surgery in the digestive tract. Near-infrared fluorescence (NIRF) imaging is a means to intraoperatively visualize anastomotic perfusion, facilitating fluorescence image-guided surgery (FIGS) with the purpose to reduce the incidence of AL. The aim of this study was to analyze the current practices and results of NIRF imaging of the anastomosis in digestive tract surgery through the EURO-FIGS registry. Methods: Analysis of data prospectively collected by the registry members provided patient and procedural data along with the ICG dose, timing, and consequences of NIRF imaging. Among the included upper-GI, colorectal, and bariatric surgeries, subgroup analysis was performed to identify risk factors associated with complications. Results: A total of 1240 patients were included in the study. The included patients, 74.8% of whom were operated on for cancer, originated from 8 European countries and 30 hospitals. A total of 54 surgeons performed the procedures. In 83.8% of cases, a pre-anastomotic ICG dose was administered, and in 60.1% of cases, a post-anastomotic ICG dose was administered. A significant difference (p < 0.001) was found in the ICG dose given in the four pathology groups registered (range: 0.013–0.89mg/kg) and a significant (p < 0.001) negative correlation was found between the ICG dose and BMI. In 27.3% of the procedures, the choice of the anastomotic level was guided by means of NIRF imaging which means that in these cases NIRF imaging changed the level of anastomosis which was first decided based on visual findings in conventional white light imaging. In 98.7% of the procedures, the use of ICG partly or strongly provided a sense of confidence about the anastomosis. A total of 133 complications occurred, without any statistical significance in the incidence of complications in the anastomoses, whether they were ICG-guided or not. Conclusion: The EURO-FIGS registry provides an insight into the current clinical practice across Europe with respect to NIRF imaging of anastomotic perfusion during digestive tract surgery.

Background and Aims: Laparoscopic sleeve gastrectomy (LSG)-related fistulas are important and potentially fatal complications. We aimed at determining the incidence, predictive factors, and management of recurrence of post-LSG fistulas. Methods: This is a retrospective cohort study of 12 consecutive patients with LSG fistulas managed endoscopically between 2008 and 2013. We analyzed factors associated with recurrence of post-LSG fistulas and the efficacy of a primarily endoscopic approach to manage fistula recurrence. Results: The average age at fistula detection after LSG was 43.3 ± 10.9 years, and 10 (83%) patients were female. The median interval between surgery and initial fistula detection was 14 (4-145) days. Fistulas were located at the gastric cardia in 9/12 patients. A median of 4 (1-10) endoscopies were performed per patient until all fistulas were successfully closed. The median follow-up was 30.5 (15-72) months. Fistula recurrence was detected in 3 (25%) female patients with an average age of 31.7 ± 7.9 years after a median of 119 (50-205) days of the initial fistula closure. Fistulas in all 3 patients recurred at the gastric cardia and were successfully managed endoscopically. There was a second recurrence in 1 patient after 6 months, and she was re-operated with anastomosis of a jejunal loop at the site of the fistula orifice at the gastric cardia. We did not find any factors at initial fistula detection that were significantly associated with fistula recurrence. There were no deaths related to initial fistula after LSG and fistula recurrence. Conclusions: A primarily endoscopic approach is an effective and safe method for the management of fistulas after LSG. Fistula recurrence occurred in 25% of patients and was managed endoscopically. Key Messages: Although we could not define predictive factors of post-LSG fistula recurrence, it is a clinical reality and can be managed endoscopically. Objectivos: As fistulas pós-gastrectomia vertical (sleeve) laparoscópica (LSG) são complicações importantes e potencialmente fatais. O objectivo do estudo foi determinar a incidência, factores preditivos e manejo da recorrência de fistulas pós LSG. Métodos: Estudo retrospectivo de 12 doentes com fistulas pós LSG manejados endoscopicamente entre 2008 e 2013. Analisámos factores associados à recorrência de fistulas pós LSG e a eficácia da abordagem endoscópica. Resultados: Idade média na detecção das fistulas pós LSG foi de 43.3 ± 10.9 anos e 10 (83%) doentes eram mulheres. O intervalo mediano entre a cirurgia e a detecção da fistula inicial foi de 14 (4-145) dias. As fistulas localizaram-se no cárdia em 9/12 doentes. Foram realizadas em mediana 4 (1-10) endoscopias por doente até ao encerramento eficaz das fistulas. O tempo mediano de seguimento foi de 30.5 (15-72) meses. A recorrência das fistulas foi detectada em 3 (25%) doentes, todas mulheres, com idade média de 31.7 ± 7.9 anos, após um tempo mediano de 119 (50-205) dias após encerramento da fistula inicial. As recorrências das fistulas nas três doentes ocorreram no cárdia e foram manejados endoscopicamente. Houve uma segunda recorrência de fistula numa doente após 6 meses que foi reoperada com anastomose de ansa jejunal no local do orifício de fistula no cárdia. Não conseguimos determinar factores na altura da detecção da fistula inicial pós LSG significativamente associados com recorrência de fistulas. Não houve mortalidade associada às fistulas pós LSG (inicial ou recorrência). Conclusões: A abordagem primariamente endoscópica das fistulas pós LSG é um método eficaz e seguro. A recorrência de fistulas ocorreu em 25% dos doentes. As recorrências de fistulas pós LSG são manejáveis endoscopicamente. Mensagens chave: Embora não tenhamos conseguido definir factores preditivos de recorrência de fistulas pós LSG, a recorrência de fistulas é uma realidade clínica e é manejável endoscopicamente.
