Abstract
Background: The spread of colorectal cancer screening has increased the percentage of patients with early-stage rectal cancer; at least 30% of patients are diagnosed with a clinical-stage cT1 or pT1 after endoscopic excision. In this subgroup of patients, the real advantage of total mesorectal excision (TME) over local excision (LE) is the ability to remove mesorectal nodes, which are metastatic in less than 20% of cases.
Method: To solve the unmet need for accurate nodal staging in patients with cT0/cT1, cN0 rectal cancer, we designed a pilot study that associates LE with mesorectal fluorescence-guided nodal sampling. From November 2018 to November 2023, we enrolled a total of ten patients with T1N0M0 rectal cancer. After extensive staging and adequate information, patients underwent endoscopic indocyanine green (ICG) infiltration and transanal local excision associated with laparoscopic fluorescence-guided mesorectal nodal sampling.
Results: After a median follow-up of 24 months (range 1-63 months), no case of local or nodal recurrence was observed. All patients were spared from ostomy and lower anterior resection syndrome.
Conclusions: In selected cases of cT0-1cN0 rectal cancer, transanal local excision plus ICG lymph nodal sampling is a feasible surgical option that increases the rate of organ preservation. Further studies are needed to identify the patients most likely to benefit from this minimally invasive strategy.
期刊介绍:
Minimally Invasive Therapy and Allied Technologies (MITAT) is an international forum for endoscopic surgeons, interventional radiologists and industrial instrument manufacturers. It is the official journal of the Society for Medical Innovation and Technology (SMIT) whose membership includes representatives from a broad spectrum of medical specialities, instrument manufacturing and research. The journal brings the latest developments and innovations in minimally invasive therapy to its readers. What makes Minimally Invasive Therapy and Allied Technologies unique is that we publish one or two special issues each year, which are devoted to a specific theme. Key topics covered by the journal include: interventional radiology, endoscopic surgery, imaging technology, manipulators and robotics for surgery and education and training for MIS.
