Background: Anastomotic insufficiency is a feared complication after sleeve lobectomy. Bronchoscopy can help to identify anastomoses at risk. We evaluated negative predictors of anastomotic healing using a bronchoscopic grading system in a large collective of lung cancer patients.
Methods: From 2006 to 2019, 541 sleeve lobectomies for lung cancer were performed. Anastomotic healing was documented by bronchoscopy on the seventh postoperative day using a standardized classification system for anastomotic grading (grade 1, perfect healing to 5, insufficiency). Grade 1 and 2 were considered satisfactory and the patients were discharged. Grade 3 or higher was considered critical. These patients received systemic antibiotic treatment and re-bronchoscopy was performed 4 days later.
Results: In 18.5% of the patients, the anastomosis was assessed as critical. 19% of patients with critical anastomosis on the 7th postoperative day developed anastomotic insufficiency during the postoperative course, compared to 0.2% in patients with satisfactory anastomotic healing. Bilobectomies, low preoperative forced expiratory volume in 1 second (FEV1) values, high preoperative levels of C-reactive protein and neoadjuvant radiation were identified as independent risk factors for critical anastomotic healing.
Conclusions: Bronchoscopic assessment of anastomotic healing is an effective tool to identify critical anastomoses. Neoadjuvant radiation, bilobectomies and acute or chronic inflammation were independent risk factors for bronchial healing disorders and should be considered at the planning stage of surgery.

Background/objectives: Anastomotic leakage (AL) is one of the most concerning complications following gastrectomy. The aim of this study was to assess and compare the predictive accuracy of C-reactive protein (CRP), procalcitonin (PCT), the neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR), fibrinogen, and the mean platelet volume (MPV) in the early diagnosis of post-gastrectomy AL.
Methods: A prospective bicentric observational study was conducted including all patients undergoing elective gastrectomy between August 2018 and December 2022.

Bilio-biliary anastomosis (BBA) is a critical surgical procedure that is performed with the objective of restoring bile duct continuity. This procedure is often required in cases where there has been an injury to the extrahepatic bile ducts or during liver transplantation. Despite advances in surgical techniques, the healing of BBA remains a significant challenge, with complications such as stricture formation and leakage affecting patient outcomes.

Article Synopsis
- The study investigates the effectiveness of 3D virtual modeling (3DVM) and indocyanine green perfusion angiography (ICGPA) in improving surgical planning and outcomes during laparoscopic right hemicolectomy for colon cancer.
- Advanced imaging techniques allowed for precise preoperative planning, showing a high correlation with intraoperative findings, which enabled better decisions regarding vessel management and anastomotic site selection.
- The results indicate that using 3DVM and ICGPA not only enhances the surgical team’s ability to visualize vascular structures but also leads to successful surgeries without postoperative complications.

Background: The wound healing effects of a specialized amino acid supplement containing calcium beta-hydroxy-beta-methylbutyrate, L-arginine, and L-glutamine (HMB/Arg/Gln) have been reported. This study aimed to investigate the effectiveness of HMB/Arg/Gln in the perioperative management of patients with thoracic esophageal cancer.
Methods: This retrospective cohort study included 131 patients who underwent esophagectomy for thoracic esophageal cancer between January 2016 and November 2023.

Background: Intraabdominal adhesions increase the incidence and length of surgical complications. Many anti-adhesive agents have been used for this purpose, but no definitive solution has yet been found. Studies on the prevention and reduction of anastomotic leakage, therefore, remain up to date.
