Ling classification applied in the preoperative safety and effectiveness assessment of POEM.

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
BACKGROUND AND STUDY
aimsAt present, peroral endoscopic myotomy (POEM) has been considered as the recommended treatment for achalasia, as it causes trauma to a smaller area and has fewer short-term serious complications than other treatments. However, due to the different morphology of esophagus, not all the patients with achalasia are eligible to receive POEM surgery. And the purpose of our study was to apply Ling classification, which proser Linghu put forward in 2011, in the preoperative assessment of POEM, expecting to reduce the occurrence rate of complications during or post-POEM. PATIENTS AND
methodsThe clinical data of 341 achalasia patients were collected and classified, according to the endoscopic pictures related to the middle and the lower parts of the esophagus. The correlation between Ling classification and LESP or Eckardt score was analyzed for the efficiency estimation, and the correlation of Ling classification and incidence of complications was counted for the safety evaluation.
resultsLing classification was correlated with the LESP of 95 patients and Eckardt score of 131 patients. Compared to preoperative data, post-POEM LESP and Eckardt score both decreased significantly in all types of Ling classification (p < 0.05), while no significant difference in the decrease degree of either LESP or Eckardt score was found among different types of Ling classification (p > 0.05). This means Ling classification may not directly affect the postoperative efficacy of POEM. By analyzing the correlation between Ling classification and intraoperative complications, we found that the differences of total complications, gas-related complication and mucosal injury were all significant among all types of Ling classification (p < 0.05).
conclusionsLing classification can be applied in the preoperative assessment of the safety and efficacy of POEM, and it might provide a guideline for how to reduce the complications during POEM surgery.
