Intraoperative hydrocolonic ultrasonography for localization of small colorectal tumors in laparoscopic surgery.
Article in Surgical endoscopy, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundAccurate localization of small colorectal cancers and polyps during laparoscopic resection may be difficult and requires precise and reliable localization techniques. This study aimed to assess the usefulness of intraoperative ultrasonography (IOUS) combined with retrograde saline instillation in locating small colorectal cancers and polyps during laparoscopically assisted colectomy.
methodsThe study investigated 14 patients with left-sided lesions of the colon and rectum necessitating preoperative marking. During laparoscopically assisted colorectal surgery, the large bowel was filled with saline solution by gravity, then scanned with a 5- to 10-MHz laparoscopic ultrasound probe.
resultsIn all patients, both polyps and small cancers were clearly detected by IOUS. Furthermore, the technique was found to be easily mastered and performed. The mean detection time was 11 min. Polyps were seen as hypodense masses protruding from the bowel mucosa, whereas invasive cancers had both hypo- and hyperdense regions with sonographically appreciable penetration through bowel layers.
conclusionIntraoperative laparoscopic ultrasonography in conjunction with saline instillation can serve as a useful tool that allows the surgeon to locate small nonpalpable tumors during laparoscopically assisted resection of colorectal cancer.
