Postoperative colonic motility after tropisetron and a standardized meal in patients undergoing conventional colorectal surgery.
Article in International journal of colorectal disease, 2007. 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
backgroundEarly postoperative enteral nutrition is advantageous for the recovery of colonic motility but may be limited by abdominal distension, nausea, and vomiting. We aimed to investigate the tolerance of a standardized meal after pretreatment with the 5-hydroxytryptamine-3-receptor antagonist tropisetron and to study the concomitant colonic motility.
methodsColonic motility and tone were recorded on postoperative day 1 to 3 with a combined manometry/barostat recording catheter in 12 patients who underwent open colorectal surgery with an anastomosis in the distal colon or rectum. The study protocol consisted of 30 min of baseline recordings followed by 5 mg of tropisetron intravenously. Then, motility was recorded for another 30 min before patients ingested a standardized meal to trigger the gastrocolonic response. Postprandial motility was recorded for the subsequent 60 min.
resultsThe colonic motility index increased after administration of tropisetron on all three postoperative days (day 1: 34+/-11 vs 122+/-48, day 2: 55+/-19 vs 101+/-25, and day 3: 42+/-16 vs 93+/-33 mmHg/min; p<0.05). No further increase of the motility index was observed postprandially. Frequency and amplitude of contractions were virtually unaffected by tropisetron and the meal. Barostat bag volume decreased postprandially in the proximal bag on the third, and in the distal bag on the first and second postoperative day (p<0.05). Patients' condition was unaffected by the standardized meal after tropisetron administration.
conclusionsTropisetron may enhance colonic motility in the early postoperative period; however, the gastrocolonic response was impaired thereafter. High caloric food intake is well tolerated early after surgery after tropisetron pretreatment.
