The learning curve of single-port laparoscopic appendectomy performed by emergent operation.
Article in World journal of emergency surgery : WJES, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
backgroundSingle-port laparoscopic appendectomy (SPLA) has the advantage of minimizing abdominal incision scars with patient satisfaction. However, it has the following disadvantages: it provides a narrower surgical field than conventional laparoscopic appendectomy, which requires a considerably longer operative time to achieve surgical skills. This study was conducted to evaluate the learning curve for SPLA.
methodsThis study included a total of 120 patients with acute abdomen who visited our emergency department and were diagnosed with acute appendicitis between March 2013 and February 2015. They underwent SPLA by a single surgeon. Patients were divided into 4 groups of 30 patients each according to operation dates. Operative time, time to resume oral intake, length of hospital stay, and postoperative complications were analyzed.
resultsThe mean operative time was 59.9 ± 19.9 min. It was shortened after completion of 30 operations and remained unchanged until it was further shortened after completion of 90 operations. There was no significant difference in time to resumption of oral intake or length of hospital stay between the 4 groups. Postoperative complications occurred in 18 patients, but the frequency of the complications was not significantly different between the 4 groups.
conclusionsThe results of this study suggest that surgeons can achieve surgical skills for SPLA after completion of 30 operations and more experienced surgical skills by SPLA successfully after completion of 90 operations.
