Prospective Evaluation of the Impact of New Circular Stapler Technology in Colorectal Anastomosis: the PROTECT Study

Overview

The goal of this observational study is to evaluate whether different circular stapling devices influence the success of the surgical connection between the bowel ends after colorectal cancer surgery in patients undergoing colorectal resection using different stapling devices. The main question this study aims to answer is whether different circular stapling devices affect the risk of a leak developing at the site where the bowel is reconnected after colorectal cancer surgery. Researchers will compare three types of circular stapling devices commonly used in clinical practice (two-row, three-row, and powered circular staplers) to determine whether they are associated with different risks of leakage at the site where the bowel is reconnected after colorectal cancer surgery. Participants will receive standard medical care. Taking part in this study will not affect their treatment, and no additional procedures, tests, or visits are required as part of the study.

Interventions

  • Device Two-row circular stapler
    Two-row circular stapler: circular stapling device creating a colorectal anastomosis using two concentric rows of staples. The device is used according to routine clinical practice during colorectal resection with primary anastomosis.
  • Device Three-row circular stapler
    Three-row circular stapler: circular stapling device creating a colorectal anastomosis using three concentric rows of staples with graduated staple heights designed to optimize tissue compression and sealing. The device is used according to routine clinical practice during colorectal resection with primary anastomosis.
  • Device Powered circular stapler
    Powered circular stapler: electrically powered circular stapling device used to create a colorectal anastomosis. The powered mechanism is designed to standardize tissue compression and stapler firing while reducing operator-dependent variability. The device is used according to routine clinical practice during colorectal resection with primary anastomosis.

Primary outcome measures

  • Anastomotic leakage [Time frame: From the date of surgery until the first occurrence of anastomotic leakage, assessed up to 30 days after surgery]
Secondary outcome measures (3)
  • Postoperative complications [Time frame: From the date of surgery until the first occurrence of any postoperative complications, assessed up to 30 days after surgery]
  • Reintervention rate [Time frame: From the date of surgery until the first reintervention, assessed up to 30 days after index surgery]
  • Postoperative length of stay [Time frame: From date of surgery until the date of hospital discharge, average 1 week]

Eligibility criteria

Inclusion criteria

  • Adult patients (18 years or older)
  • Patients undergoing elective surgery, either open or minimally invasive (laparoscopic or robotic), for anterior rectal resection, sigmoid resection, or left hemicolectomy for colorectal cancer with concomitant colorectal anastomosis (Knight-Griffen technique) using one of the circular stapler types under investigation (two-row CS, three-row CS, PCS).

Exclusion criteria

  • Patients undergoing emergency surgery
  • Patients undergoing additional surgical procedures during the same operation (e.g., cholecystectomy, liver resection, etc.)
  • Patients with documented metastases at preoperative staging (cM+)
  • Patients under 18 years of age
  • Lack of informed consent

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
