Laparoscopic transduodenal ampullectomy: initial experience from a single center.
Article in Frontiers in oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Background: Laparoscopic transduodenal ampullectomy (LTDA) is a function-preserving surgery for pre-malignant tumors of the ampulla of Vater (AoV). However, it is technically challenging, and only a few case reports of LTDA are available in the literature. Methods: A total of 43 cases of pre-malignant tumors of AoV were operated in West China Hospital, Sichuan University between January 2017 and July 2022. Among these patients, 9 patients (group 1) underwent LTDA, 19 patients (group 2) underwent laparoscopic pancreaticoduodenectomy (LPD), and 15 patients (group 3) underwent open transduodenal ampullectomy (OTDA). Prospective collection and retrospective analysis of the demographic characteristics, intraoperative variables, and postoperative variables were carried out. Results: The patients in the three groups were comparable in terms of sex, age, body mass index, tumor size, and preoperative blood tests. In comparison to the patients in group 2, the patients in group 1 were found to require less operative time (159.7 ± 47.5 min vs. 298.1 ± 62.6, Conclusion: Therefore, LTDA was found to be safe and feasible in the setting of pre-malignant tumors of AoV in well-selected patients. However, multidisciplinary preoperative planning is essential before the surgery.
