1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundUreteral 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.

methodsOne 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.

resultsAge, 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%).

conclusionsFUC 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.
