Fluorescence-guided laparoscopic-assisted transabdominal intersphincteric resection for ultralow rectal cancer: report of a surgical technique.

ABSTRACT: This paper describes a case in which fluorescence-guided laparoscopic-assisted transabdominal intersphincteric resection (ISR) was applied in a patient with ultralow rectal cancer. This study presented the successful dual-application of fluorescence technique. The patient was a 72-year-old male with a body mass index (BMI) of 22.6 kg/m². The lower edge of the rectal adenocarcinoma was 4 cm away from the anal verge. The clinical stage based on pelvic magnetic resonance imaging (MRI) was cT2N0M0. We performed fluorescence-guided and laparoscopic-assisted transabdominal ISR for the patient. About 24 hours before the operation, indocyanine green (ICG; 2.5 mg/mL) was injected into four sites of the submucosa layer around the tumor under colonoscopy for lymph node (LN) identification.
