About this study

This is a randomized, controlled, parallel, multicenter study to determine the difference in post-operative anastomotic leak rate in low anterior resection procedures where colon and rectal tissue perfusion is evaluated using PINPOINT as an adjunct to standard surgical practice compared to surgical procedures performed according to standard surgical practice alone.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

Inclusion Criteria:

  • 18 years of age and older
  • Undergoing an LAR for the treatment of rectal neoplasms
  • Subjects with rectal neoplasm(s) may be treated with or without neoadjuvant therapy. Neoadjuvant therapy must have been completed ≥6 weeks prior to surgery

  • Undergoing a robotic or robotic assisted (da Vinci® Surgical System) LAR
  • Undergoing ileoanal reconstruction, proctocolectomy, abdominoperineal resection, Hartmann's procedure, Hartmann's reversal or multiple synchronous colon resections (e.g., LAR and concomitant right colectomy)
  • Diagnosis of Stage IV rectal cancer or locally advanced rectal cancer undergoing extended en bloc operations
  • Intra-operative incidental finding of Stage IV cancer with isolated metastasis of a cumulative size of ≤ 2 cm does not exclude the subject
  • Diagnosis of inflammatory bowel disease
