Learning curve for the combined trans-oral and chest approach to endoscopic selective neck dissection: a cumulative sum (CUSUM) analysis.
Article in Surgical endoscopy, 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
backgroundThe combined trans-oral and chest approach is a novel technique for endoscopic selective neck dissection (SND), with satisfactory oncological safety and cosmetic results. However, this hybrid approach is difficult, and the learning curve remains unclear. In this study, we aimed to evaluate the short-term outcomes for this hybrid approach, and to define the associated learning curve.
methodClinical data and surgical outcomes of 58 PTC patients who underwent endoscopic SND via combined trans-oral and chest approach between September 2020 and April 2023 were retrospectively reviewed. The cumulative sum (CUSUM) sequential analysis technique is used to detect change, and has been applied for the evaluation of learning curves.
resultsThe study population included 58 patients (40 females, 18 males), with mean age of 38.9 ± 12.7 years and average body mass index of 22.6 ± 4.8 kg/m
conclusionsAfter the experience acquired using endoscopic SND via combined trans-oral and chest approach to treat PTC in 20 patients, the number of complications decreased significantly. Compared to data collected for the initial phase, data collected for the mature phase showed trends toward decreased operating time.
