Utility and challenges of ureteral visualization using a fluorescent ureteral catheter in high risk surgeries for colorectal cancer. Surg Endosc 2024:10.1007/s00464-024-11211-0. [PMID: 39266754 DOI: 10.1007/s00464-024-11211-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2024] [Accepted: 08/19/2024] [Indexed: 09/14/2024]
Abstract
BACKGROUND Ureteral injury occurs in 0.3-1.5% of colorectal cancer surgeries. Devices to visualize the ureteral course and avoid ureteral injury are required for minimally invasive surgery (MIS). The NIRC™ fluorescent ureteral catheter (FUC) is a versatile ureteral visualization device currently available in Japan that can be used in combination with a variety of laparoscopic and robotic systems. In this study, we examined the outcomes of high-risk patients who underwent colorectal cancer surgery with FUC insertion. METHODS One hundred forty-one patients who underwent MIS for colorectal cancer and colorectal cancer recurrence at our institute between January 2021 and May 2024 underwent preoperative FUC insertion because of the high risk of ureteral injury and surgical difficulty. For these patients, patient background data and short-term outcomes were examined. The results are expressed as the median and interquartile range. RESULTS Age, 70 [60-78]; M:F(n), 84:57; BMI, 22.1 [19.7-24.7]; T4 (TNM classification), 52 cases (36.9%); preoperative intestinal obstruction, 45 cases (31.9%); abscess formation, 30 cases (21%); surgical history, 70 cases (50%); recurrent cancer, 14 cases (9.9%); preoperative chemo-radiotherapy, 28 cases (19.9%); time required for FUC insertion, 12 [9-19] minutes; operation time, 412 [309-552] minutes; blood loss, 10 [5-30] ml; open conversion, 0 cases; postoperative hospitalization, 12 [9-17.5]; circumferential resection margins < 1 mm (rectal surgery), 4/87 cases (4.6%); comorbidities, 0 ureteral injury, 1 urethral injury during FUC insertion (0.7%) and 16 CD Grade 3 or higher cases (11%). CONCLUSIONS FUC may improve the safety of MIS and reduce blood loss in addition to preventing ureteral injury and is expected to have oncological advantages for ensuring the margin of the tumor without fear of ureteral injury. However, the time required for and complications associated with FUC are challenging. New methods for less invasive and easier ureteral visualization may be needed.

Abstract
Transplant ureteral stenosis (US) is a complication of kidney transplantation (KT) that sometimes adversely affects kidney function. Endoscopic treatment may be selected as the initial treatment; however, the recurrence rate is high. Ureteral reconstruction is necessary as a secondary treatment, but it is often difficult to identify the transplanted ureter due to reoperation; therefore, transplanted ureter and renal arteriovenous injury are intraoperative complications that should be noted. The Near-Infrared Ray Catheter (NIRC™) fluorescent ureteral catheter (NIRFUC) fluoresces by illuminating near-infrared rays, facilitating the identification of intraoperative ureteral locations. Herein, we report the case of a 34-year-old woman who developed US following KT. She underwent balloon dilation for transplant US, but the stenosis recurred; therefore, she underwent transplant ureteral auto-ureteral anastomosis. Although it was difficult to identify and detach the transplanted ureter owing to adhesions, the use of NIRFUC facilitated the identification of the ureter in the surgical field and enabled safe end-side anastomosis between the transplanted ureter and the autologous ureter. In conclusion, although there is no consensus on the best method for complex transplantation-related US cases, NIRFUC may be used to safely identify and perform surgeries on the ureter.

Survival outcomes after synchronous para-aortic lymph node metastasis in colorectal cancer: A systematic review. J Surg Oncol 2023; 127:645-656. [PMID: 36350234 PMCID: PMC10100040 DOI: 10.1002/jso.27139] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 10/17/2022] [Accepted: 10/21/2022] [Indexed: 11/11/2022]
Abstract
BACKGROUND Synchronous para-aortic lymph node metastasis (PALNM) in colorectal cancer (CRC) is a relatively rare clinical entity. There is a lack of consensus on management of these patients, and the role of para-aortic lymph node dissection (PALND) remains controversial. This systematic review aims to describe the survival outcomes in colorectal cancer with synchronous PALNM when lymph node dissection is performed. METHODS A systematic review of Pubmed, Embase and Web of Science databases for PALND in CRC was performed. Studies including patients with synchronous PALNM undergoing resection with curative intent, published from the year 2000 onwards, were included. RESULTS Twelve retrospective studies were included. Four studies reported survival outcomes for rectal cancer, two for colon cancer and six as colorectal. Survival outcomes for 356 patients were included. Average 5-year overall survival (OS) was 22.4%, 33.9% and 37.7% in the rectal, colon and colorectal groups respectively. Three year OS in the groups was 53.6%, 46.2% and 65.7%. CONCLUSION There remains a lack of quality data to confidently make recommendations regarding the management of synchronous PALNM in colon and rectal cancer cohorts. Retrospective data suggests a benefit in highly selective cohorts and therefore a case-by-case evaluation remains the standard of care.
