Prior surgery characteristics predict adhesions in robotic colorectal cancer resection
A single-center retrospective cohort study of 746 patients examined how prior abdominal surgery (PAS) relates to adhesions and short-term outcomes after robotic colorectal cancer resection. Certain prior-surgery characteristics predicted adhesions or adhesiolysis, while matched short-term outcomes were comparable between patients with and without PAS.
- Cancer-related and open prior surgery predicted abdominal wall adhesions.
- Middle- and lower-abdominal prior surgery predicted adhesiolysis.
- Matched short-term outcomes were comparable with and without prior surgery.
Researchers reviewed 746 consecutive patients who underwent robotic colorectal cancer resection at one institution from January 2018 to December 2025; 200 had a history of prior abdominal surgery. They assessed associations between specific PAS characteristics and intraoperative adhesions or adhesiolysis, and compared short-term outcomes after propensity score matching.
Among patients with PAS, 46.0% had adhesions and 36.0% underwent adhesiolysis. Cancer-related prior surgery was associated with abdominal wall adhesions (adjusted odds ratio [aOR] 3.78, 95% CI 1.36–11.4), as was prior open surgery (aOR 6.06, 95% CI 2.47–16.9). Among patients with adhesions, middle- and lower-abdominal prior surgery were associated with adhesiolysis (aOR 15.2 and 12.2, respectively). After matching, operative time, console time, blood loss, conversion, and severe complications were comparable between groups.
The findings suggest that the type and location of previous surgery may help characterize technical complexity beyond simply recording PAS as present or absent. The retrospective, single-center design limits generalizability, and the study reports short-term outcomes only; it does not establish that changing surgical planning based on these factors improves outcomes.
In practice
For teams performing robotic colorectal cancer resection, the study suggests that the details of prior abdominal surgery—not only its presence—may help anticipate adhesions and the need for adhesiolysis. Cancer-related and open prior surgery were associated with abdominal wall adhesions, while middle- or lower-abdominal surgery predicted adhesiolysis among patients with adhesions. This is retrospective evidence from one institution; matched short-term outcomes were comparable, and the findings do not establish that a different operative plan improves outcomes.
