Background/aim: The purpose of this study was to reveal the safety and efficacy of additional surgical resection (ASR) for high-risk T1 colorectal cancer (CRC) after endoscopic resection (ER).
Patients and methods: We retrospectively analyzed 191 patients with high-risk T1 CRC after ER.
Results: The ASR was performed in 176 (92.1%) patients and 15 (7.9%) rejected ASR. All patients that underwent ASR experienced R0 resection; laparoscopic surgery was performed in 159 (90.3%) patients. Clavien-Dindo complications ≥grade II occurred in 33 patients (18.8%). Anastomotic leakage (8.5%) and ileus (5.7%) were the most frequent complications. The anus function was preserved in all patients. Metastatic lymph node was detected in 21 (11.9%) patients. There were no deaths or relapses in patients with ASR. One patient without ASR (6.7%) had a lymph node recurrence.
Conclusion: ASR was safe and effective and is recommended for high-risk T1 CRC patients after ER. A satisfactory long-term outcome can be achieved.
