Multidimensional assessment of the learning curve of intracorporeal anastomosis during laparoscopic right colectomy.
Article in Langenbeck's archives of surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeAfter resection during a laparoscopic right colectomy (LRC), reconstruction can be conducted with an intracorporeal (IA) or extracorporeal anastomosis. Although IA benefits are well documented, its implementation has been slow due to a steep learning curve (LC) mainly associated with intracorporeal suturing. The aim of this study is to assess the LC of IA in LRC.
methodsConsecutive patients undergoing a LRC with IA between January 2016 and June 2023 were included. Clinical, perioperative, and histopathological variables were collected. Correlation and cumulative sum (CUSUM) analyses between the operating time and case number were performed. 'Surgical success' as a composite outcome was also analysed by performing a CUSUM plot. Completion LC case number was determined based on these analyses. Pre-LC and post-LC perioperative outcomes were compared.
resultsTwo-hundred-and-ninety patients underwent a LRC during the study period. Sixty-seven met inclusion criteria. Correlation analysis identified a significant operating time reduction with increasing case numbers (p = 0.034). Total complications during implementation period were 25,3%, with 6% of severe complications. Operative time CUSUM analysis identified a consistent downwards trend after case 36 and surgical success CUSUM analysis after case 37. Two phases were established: pre-LC (case 0-37th) and post-LC (38th-67). Pre-LC and post-LC revealed a significant decrease in operative time (187vs177.8 min;p = 0.016), and length of stay (4vs3 days;p < 0.001). No difference between overall complications, severe complication, or reoperation rates were detected.
conclusionThe LC of laparoscopic IA can be achieved after 37 cases in centres with experience in advanced laparoscopic surgery. Further studies will be required to confirm these results.
