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

objectiveThere is limited literature on the impact of the extent of resection on short-term outcomes in patients with ulcerative colitis (UC) in an elective setting. The aim of this study was to better understand the impact of approach and extent of resection on short-term outcomes for patients undergoing total proctocolectomy (TPC) and subtotal colectomy (STC) for UC.

methodsPatients with UC who underwent elective TPC or STC were captured from the ACS-NSQIP® 2011-2018 database and divided into four cohorts: Open TPC (O-TPC), Laparoscopic TPC (L-STC), Open STC (O-STC), and Laparoscopic STC (L-STC). Baseline and perioperative variables were compared between the four groups alongside 30-day mortality and 30-day complication rates.

resultsOf 3387 patients, 368 (10.9%) underwent O-STC, 406 (12%) underwent O-TPC, 1958 (58%) underwent L-STC, and 655 (19%) underwent L-TPC. Overall rate of prolonged length of stay (LOS) was 27% and 9% needed a blood transfusion. There was no difference in the risk of complications between open TPC and open STC. Those who had open surgery had a higher risk of complications and prolonged LOS. Patients who had L-TPC had prolonged LOS compared to patients who had L-STC, but less compared to those who had O-STC.

conclusionElective surgery for UC is associated with high rates of prolonged LOS and blood transfusion despite MIS approaches. Short-term outcomes and LOS are more impacted by the operative approach than the extent of resection. Despite this laparoscopic TPC has higher rates of prolonged LOS when compared to laparoscopic STC.
