Low workload for pelvic neuromonitoring supported by teleconsulting: technical considerations and feasibility.
Article in Techniques in coloproctology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundPelvic intraoperative neuromonitoring (pIONM) prevents functional disturbances after low anterior rectal resection. We investigated the workload of performing pIONM under telementoring conditions to catalyze translation into surgical practice.
methodsSix patients with rectal cancer underwent nerve-sparing total mesorectal excision (TME) with laparoscopic or robot-guided pIONM. A telementoring system enables cross-reality interaction, with online communication between a briefed on-site surgeon at the operating room and a remote mentor at an external hospital. The validated NASA Task Load Index (NASA-TLX) was used to measure the workload for standardized pIONM.
resultsThe pIONM was installed and performed without any problems. It required a median 7 min stimulation time (range 7-10 min) and confirmed nerve-sparing TME in all six patients. Remote and on-site telepresence required a median 31 min (range 24-44 min), enabling adequate application training for a first-time user. The overall NASA-TLX-based workload realizing pIONM was a median 8.7 (range 3.3-16.3) points. There was no significant difference in TLX between on-site and remote surgeons (p = 0.180). Overall workload was highest for the first-time user but decreased upon repetition. Significantly higher values were found in the following subscales for the surgeon performing pIONM: physical demand (p = 0.002) and temporal demand (p = 0.03).
conclusionInitiation of pIONM supported by teleconsulting is feasible and requires a low workload.
