Unexpected right-sided sigmoid colon in laparoscopy: A case report and review of literature.
Article in World journal of gastrointestinal surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe presence of a right-sided sigmoid colon is a rare anatomical variation usually discovered incidentally during surgical interventions. This case report details an unexpected right-sided sigmoid colon identified during a laparoscopic appendectomy and examines the pertinent literature to explore its clinical importance. CASE SUMMARY: A 71-year-old woman presented with acute appendicitis. A preoperative computed tomography (CT) scan showed peri-appendiceal inflammation but no significant anatomical abnormalities. During laparoscopic surgery, an unexpected finding was encountered: The sigmoid colon was situated on the right side and exhibited an abnormal relationship with the cecum and ascending colon. Postoperative pathological examination confirmed appendicitis with no additional pathological findings. The right-sided sigmoid colon anomaly was verified through intraoperative assessment and later re-evaluation with CT and colonographic imaging. The patient underwent a laparoscopic appendectomy and experienced a smooth postoperative recovery.
conclusionThis case highlights the necessity of being attentive to anatomical variations during laparoscopic surgery, particularly when managing appendicitis. A review of the literature indicated that the occurrence of a right-sided sigmoid colon is infrequent and may be associated with anomalies in midgut rotation during embryonic development. Awareness of this variation can help prevent surgical complications and inform future clinical practice.
