Article Abstract
Background: The da Vinci Single-port (SP) system is designed to facilitate single-incision robotic surgery in a narrow space. We developed a new procedure of intersphincteric resection (ISR) using the SP platform and evaluated the technical safety and feasibility of this procedure for the treatment of very low rectal cancer.
Materials And Methods: Eleven rectal cancer patients who underwent SP robotic ISR between August 2020 and July 2021 were included. Patients' clinical characteristics, operative and pathologic findings of the patients were retrospectively analyzed.
Results: The median tumor height was 3 cm (range, 2-4 cm). A single docking was performed, and the median docking time was 3 min 10 sec (range, 2 min 50 sec-3 min 30 sec). The median total operation time was 210 min (range, 150-280 min), and the median time of pelvic dissection was 57 min (range, 45-68 min). All patients presented with negative distal resection margins [median 1 cm (range, 0.5-2.0 cm)], and only one patient had less than 1mm of circumferential resection margin (0.9 mm).
Conclusions: Our initial experience suggests that SP robotic ISR is safe and feasible.

Background: Neoadjuvant chemoradiotherapy (nCRT) is key for low rectal cancer but raises the risk of anastomotic leakage (AL). This study examines how fluorescence laparoscopic (FL) surgery reduces AL after intersphincteric resection (ISR), especially in nCRT patients.
Methods: This real-world multicenter cohort study included 533 patients undergoing laparoscopic ISR for ultra-low rectal adenocarcinoma from January 2012 to July 2023.

Background: Ultra-low rectal cancer (ULRC), defined as a lesion located within 5 cm of the anal verge, poses considerable clinical challenges because the treatment decision must balance oncological eradication with preservation of anal function. Historically, abdominoperineal resection (APR) has served as a standard approach for tumor eradication in these patients, but a permanent stoma significantly reduces patients' quality of life. In contrast, intersphincteric resection (ISR) can maintain anal function, thereby improving quality of life; however, the debate surrounding short-term postoperative complications and long-term prognosis has not been fully resolved.

Low anterior resection syndrome (LARS) is a frequent problem encountered by patients after rectal cancer surgery, significantly affecting quality of life. Though transanal irrigation (TAI) is an effective management option for LARS symptoms, the treatment can still cause rare but severe complications, such as bowel perforation. We present a very rare case of a 78-year-old patient who developed a bowel perforation after 13 years of regular TAI.

Rectal cancer ranks as the third most prevalent malignancy globally, with an estimated 1.9 million incident cases reported in 2020. The management of low rectal cancer presents significant therapeutic challenges due to its anatomical complexity, and substantially impacts patients' quality of life.

Solitary fibrous tumors (SFT) are rare mesenchymal neoplasms, and surgical resection with a negative margin is considered to have a good prognosis. It is commonly located in the thoracic cavity but rarely develops in the pelvis. One of the features of the Hugo RAS system is the independent robotic arm carts that enable high flexibility of settings and safe operations with reduced interference, even in a narrow pelvis, which may be particularly useful in surgery for pelvic masses.
