1 · What the graph read from 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.

2 · The registry

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

aimsEndoscopic stenting has proved effective in the management of post-surgical leaks but is strongly hampered by the high rate of stent migration. In this study, we evaluate our experience with a new approach involving the use of novel ultra-large expandable stents tailored for bariatric surgery leaks (Mega stents), combined with the use of the innovative over-the-scope clips (OTSC).

methodsRetrospective analysis of patients with post-bariatric surgery leaks managed at our institution by an approach combining Mega stents and over-the-scope clips.

resultsTwenty-two patients were treated for post-bariatric surgery leaks; 13 (59%) had a sleeve gastrectomy while nine (41%) had a RYGB. A total of 30 stents were inserted. Successful endoscopic insertion and removal were achieved in all patients. OTSC clips were applied in 12 patients (55%); five simultaneously with stents and seven after stent removal. Primary closure (after one endoscopic procedure) was achieved in 13 patients (59%) and in a total of 18 patients after multiple endoscopic procedures (82%). An average of 1.4 stents and 2.8 endoscopic procedures were required per patient. Stent migration occurred in four patients (18%), and all were retrievable endoscopically. Other complications included retrosternal pain and vomiting in 20 patients (91%) including one necessitating early removal, bleeding in two patients (9%), and perforation and esophageal stricture in one patient each (5%). Two mortalities were encountered, and one of them was stent-related (bleeding).

conclusionMega stents are effective in the management of post-bariatric surgery leaks. The combined use of Mega stents and OTSC clips is associated with a low incidence of migration and a low number of stents and procedures required per patient.
