“…The exclusion criteria were 1) advanced cancer invading beyond the muscularis propria, 2) cancer without any high-risk factors, and 3) clinical LNM on computed tomography (CT) images assessed by a multidisciplinary team before additional treatment. In the present study, endoscopic submucosal dissection (ESD), endoscopic mucosal resection (EMR), and transanal minimally invasive surgery (TAMIS) were defined as procedures for local resection [17,18]. The choice of local resection procedure was based on several factors including tumor size, tumor location, patient age, and comorbidities.…”

Objective: Additional surgery is considered for patients at high risk for lymph node metastasis (LNM) after local resection for early rectal cancer. Several factors are considered as indications for additional surgery, although there are currently no definitive criteria. This study aimed to clarify the need for additional surgery based on the number of risk factors for LNM and to evaluate the significance of submucosal invasion on recurrence. Methods: Patients with early rectal cancer harboring risk factors for LNM who underwent local resection between March 2005 and December 2016 were retrospectively analyzed. Associations among the number of risk factors, prognosis, and additional treatment after local resection were investigated. Results: A total of 29 eligible patients were classified into the surgery (n = 10), chemoradiotherapy (n = 7), and no-additional-treatment (NAT, n = 12) groups. Among the 29 patients, 15 patients (52%) with only one risk factor did not relapse. The NAT group harbored fewer risk factors for LNM, and 8 of the 12 patients (67%) had only deep submucosal invasion. Local recurrence occurred in one patient in the chemoradiotherapy group. The estimated 5-year overall survival rates were 88.9%, 75.0%, and 81.5% in the surgery, chemoradiotherapy, and NAT groups, respectively. There were no disease-specific deaths in the overall cohort. Conclusions: In the present study, no recurrence occurred in patients who did not receive additional surgery with deep submucosal invasion as the only risk factor. A multicenter investigation is necessary to confirm the safety of nonsurgical options.

“…Initially TAMIS was used largely for local excision of rectal lesions within the context of benign (e.g., adenomatous polyps unsuitable for endoscopic resection) or early-stage (T1) malignant tumours with a low risk for lymphatic involvement at the time of operation or local excision as a form of palliation in patients (T3 and above) who are medically unfit or unwilling to go ahead with standard oncologic surgery [10][11][12][13] . Studies report similar advantages conferred with TAMIS as for TEM when compared with conventional transanal resection, with more intact, non-fragmented specimens, negative resection margins and lower recurrence rates [6,12] .…”

Transanal minimally invasive surgery is a rapidly evolving platform surgery that is facilitating the transanal approach to colorectal surgery. Over the years since its initial description, the applications have widened and now include endoluminal and extraluminal approaches to rectal and pelvic surgery. This article discusses the various applications and future direction of research evaluating this novel technique and its role in colorectal practice.

This is a video vignette of a 57‐year‐old asymptomatic female patient. The patient underwent a screening colonoscopy which revealed a 10 mm scar in the rectum. Biopsy resulted in a well‐differentiated tubular adenocarcinoma. Computed tomography and pelvic magnetic resonance imaging confirmed tumor characteristics without distant or lymph nodal metastasis. A minimally invasive robotic transanal resection using the Da Vinci Xi platform was performed, achieving full‐thickness lesion excision with uneventful recovery. Histopathology revealed intramucosal adenocarcinoma with free margins. Local resection is advocated for selected T1 lesions and demands a thorough preoperative assessment. Robotic‐assisted surgery presents a valuable alternative for early rectal adenocarcinoma management.
