Aim: Totally laparoscopic colectomy with intracorporeal anastomosis (IA) is associated with less surgical trauma and wound related complications compared to laparoscopy-assisted colectomy with extracorporeal anastomosis. Delta shaped anastomosis is a widely popular IA technique. In this study, we discuss a construction technique for an overlapped delta-shaped anastomosis using a linear stapler with a reinforced bioabsorbable material.
Methods: We excised the bowel at a point 10 cm from the tumour on either sides and laid them in an overlapped fashion. The entry hole was created at a point 3 cm proximal to the right stump and 7 cm distal to the left stump on the antimesenteric side. Then, a 60-mm linear stapler with reinforced bioabsorbable material was inserted inside each lumen and fired. Finally, the common entry hole was fixed with a suture in the middle, the bowel was elevated holding the bioabsorbable material, and closed using the linear stapler in a delta-shaped manner.
Results: The technique was applied in five patients with tumours in the ascending, transverse, and descending colon. The median surgery time, anastomosis construction time and postoperative stay was 329 min (range 285-682 min), 19 min (range 14-29 min), and 12 days (range 9-15 days), respectively. There were no perioperative complications and only one postoperative complication.
Conclusion: The overlapped delta-shaped anastomosis technique using linear staplers with reinforced bioabsorbable material appears to be both safe and feasible.
