Analysis of outcomes for single-incision laparoscopic surgery (SILS) right colectomy reveals a minimal learning curve.
Article in Surgical endoscopy, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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-incision right colectomy has emerged as a safe and feasible alternative to standard laparoscopic resection. As with any new surgical approach, definition of the number of procedures required to optimize the technique is an important goal. Data on this learning curve for single-incision right colectomy are lacking; therefore, we report the outcomes of consecutive single-incision right colectomies to identify the procedural learning curve.
methodsWe retrospectively reviewed consecutive single-incision right colectomies performed by a single surgeon from May 2010 to May 2013. Patients were evaluated in groups of ten to minimize individual patient variability and selection bias. Demographics and peri-operative outcomes among groups were evaluated using ANOVA or Kruskal-Wallis. Statistical improvement was assessed between groups using Student T tests or Mann-Whitney U tests.
resultsSeventy consecutive single-incision right colectomies were performed during the study period. There were no differences in patient demographics over the course of the experiences, suggesting that the selection bias did not influence the outcomes. There was a statistical improvement in operative time after the first 10 cases (103 vs. 130 min, p = 0.01). A second statistical improvement in operative time occurred after 40 cases (97 vs. 114 min, p = 0.03). There was no statistical improvement in estimated blood loss, lymph node harvest, conversion rate, length of stay, or post-operative morbidity throughout the experience.
conclusionsAnalysis of our large series of consecutive cases indicates that for a surgeon trained in advanced laparoscopic techniques and given adequate case volume, the outcomes from the procedure are quickly optimized with a minimal learning curve. Operative time is optimized following 40 procedures. Identification of the learning curve is critical for surgeons wishing to implement a single-incision approach and to ensure that the outcomes are optimized prior to thorough comparison with standard laparoscopic or open approaches.
