Background: Esophageal cancer is a common malignancy in China, with anastomotic fistula being a major postoperative complication. This study compares the clinical outcomes of end-to-end anastomosis and end-to-end anastomosis with mucosal folding and burying in minimally invasive esophageal cancer surgery.
Methods: From October 2020 to March 2023, patients with esophageal cancer who underwent laparoscopic three-incision cervical anastomosis at the Fourth People's Hospital of Zigong City, were radomly assigned to receive either end-to-end anastomosis or end-to-end anastomosis followed by mucosal folding and burying. Clinical indicators, including hospitalization time, operation time, intraoperative blood loss, anastomotic fistula, and anastomotic stenosis, were compared between the two groups.
Results: A total of 107 patients werencluded, with 56 in the end-to-end anastomosis with mucosal folding and burying technique group. There were no statistically significant differences between the two groups in operation time, intraoperative blood loss, anastomotic fistula rate, and anastomotic stenosis. However, for patients who received preoperative chemoradiotherapy or chemotherapy combined with immunotherapy, the incidence of anastomotic fistula was significantly lower in the group with end-to-end anastomosis with mucosal folding and burying.
Conclusions: End-to-end anastomosis followed by mucosal folding and burying helps reduce the occurrence of anastomotic fistula, especially in patients receiving neoadjuvant chemoradiotherapy.

Background The trachea, a vital conduit in the lower airway system, can be affected by various disorders, such as tracheal neoplasms and tracheoesophageal fistulas, that often necessitate reconstruction. While short-segment defects can sometimes be addressed with end-to-end anastomosis, larger defects require tracheal reconstruction, a complex procedure with no universally successful replacement strategy. Tissue engineering offers a promising solution for tracheal repair, particularly focusing on regenerating its epithelium, which plays a critical role in protecting the respiratory system and facilitating mucociliary clearance.

Background: The magnamosis, a minimal invasive, suture-free procedure, has been used for digestive tract or vessel reconstruction, such as gastrointestinal anastomosis, bilioenteric anastomosis, and coronary artery bypass. Although some case reports have demonstrated the potential of magnamosis for the treatment of congenital rectal atresia (RA), they cannot provide strong evidence for its widespread application.
Aim: To assess the feasibility and safety of magnamosis in treating RA in dogs as compared to suturing anastomosis.

Introduction: The arterial anastomosis in renal transplantation is done either end-to-end to the internal iliac artery (IIA) or end-to-side to the external iliac artery (EIA). This retrospective study is to compare the vascular complications of these two techniques occurring in the immediate postoperative period.
Materials And Methods: The data of 111 patients who underwent renal transplantation (live and deceased) were collected from the hospital records.

Background: Tracheal implants using tissue-engineering and three-dimensional (3D) printing are promising, but challenges remain, including graft composition, anastomosis methods, and tracheal tissue regeneration. This study examines the effectiveness of various tracheal graft materials in a large animal model.
Methods: Thirty-eight tracheal surgeries were performed on a porcine large animal model, involving a 2 cm circumferential tracheal excision with end-to-end anastomosis.
