Summary

This study found no significant difference in rectal anastomosis outcomes between single stapled (SST) and double stapled (DST) techniques. Both surgical methods demonstrated comparable rates of anastomotic dehiscence, complications, and mortality in patients undergoing radical resection.

Area of Science:

  • Colorectal Surgery
  • Surgical Oncology
  • Gastrointestinal Surgery

Background:

  • Rectal anastomosis techniques are crucial for patient outcomes after radical resection.
  • Evaluating stapled techniques for rectal anastomosis is essential for surgical practice.
  • Anastomotic integrity and complications significantly impact morbidity and mortality.

Purpose of the Study:

  • To compare the efficacy and safety of single stapled anastomosis (SST) versus double stapled anastomosis (DST) in patients undergoing rectal resection.
  • To assess the rates of anastomotic dehiscence, complications, and mortality associated with each stapling technique.
  • To determine if the level of anastomosis influences outcomes between SST and DST.

Main Methods:

  • Retrospective analysis of 143 patients who underwent radical surgical resection between 1986 and 1989.

  • Comparison of single stapled anastomosis (SST) in 94 patients and double stapled anastomosis (DST) in 49 patients.
  • Anastomotic integrity assessed intraoperatively (air insufflation) and postoperatively (contrast enema).

    • Main Results:

    • Anastomotic dehiscence occurred in 20% of patients (17 SST, 12 DST), with no significant difference between techniques.
    • Dehiscence was predominantly on the posterior wall (79%) and often small (<1 cm), with evident clinical symptoms in 78%.
    • No significant differences were observed in complication rates, need for further surgery (colostomy), infection rates, or length of postoperative stay between SST and DST groups.

    Conclusions:

    • Both single stapled anastomosis (SST) and double stapled anastomosis (DST) techniques yield similar results regarding anastomotic integrity and patient outcomes.
    • The choice between SST and DST does not appear to influence the risk of anastomotic dehiscence or postoperative complications.
    • Further surgical intervention and mortality rates were comparable between the two stapling methods, suggesting equivalent safety profiles.
