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

backgroundObesity is a risk factor for failure of pouch surgery completion. However, little is known about the impact of obesity on short-term outcomes after minimally invasive (MIS) ileal pouch-anal anastomosis (IPAA). This study aimed to assess short-term postoperative outcomes in patients undergoing MIS total proctocolectomy (TPC) with IPAA in patients with and without obesity. MATERIALS AND

methodsAll adult patients (≥ 18 years old) who underwent MIS IPAA as reported in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) Participant User Files 2007 to 2018 were included. Patients were divided according to their body mass index (BMI) into two groups (BMI ≥ 30 kg/m

resultsInitially, a total of 2158 patients (402 (18.6%) obese and 1756 (81.4%) nonobese patients) were identified. After 1:1 matching, 402 patients remained in each group. Patients with obesity had a higher risk of postoperative organ/space infection (12.9%; vs. 6.5%; p-value 0.002) compared to nonobese patients. There was no difference between the groups regarding the risk of postoperative sepsis, septic shock, need for blood transfusion, wound disruption, superficial SSI, deep SSI, respiratory, renal, major adverse cardiovascular events (myocardial infarction, stroke, cardiac arrest requiring cardiopulmonary resuscitation), venous thromboembolism, 30-day mortality, and length of stay.

conclusionMIS IPAA can be safely performed in patients with obesity. However, patients with obesity have a 2-fold risk of organ space infection compared to patients without obesity. Loss of weight before MIS IPAA is recommended not only to allow for pouch creation but also to decrease organ space infections.
