Robot-Assisted Abdominoperineal Resection for Anal Fistula Cancer in a Patient with Situs Inversus Totalis: A Case Report.
Article in Surgical case reports, 2025. 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
introductionSitus inversus totalis (SIT) is a rare congenital condition characterized by a complete mirror-image reversal of thoracic and abdominal organs. This anatomic anomaly poses technical challenges in abdominal surgery, particularly in oncologic procedures requiring precise orientation and dissection. Robot-assisted surgery (RS) offers advantages such as stable visualization and enhanced dexterity, which may facilitate safe and effective surgery even in patients with reversed anatomy. However, reports of using RS for colorectal cancer in the setting of SIT remain scarce. CASE PRESENTATION: A 75-year-old man was referred to our department for evaluation and management of an anal fistula. A comprehensive diagnostic workup revealed carcinoma with cutaneous invasion arising from the anal fistula in the context of SIT. Because of the cutaneous invasion, curative resection was indicated, and the patient underwent robot-assisted abdominoperineal resection (RAPR). To accommodate the mirror-image anatomy, the surgical setup-including the positioning of robotic arms, monitors, surgeon, assistant, and scrub nurse-was reversed relative to the standard configuration. Lymphadenectomy and vascular ligation were performed using a medial-to-lateral approach adapted in a left-right inverted fashion. While pelvic dissection and lateral mobilization were conducted using the surgeon's right hand in a standard manner, cranial-side medial dissection and vascular handling were performed using the surgeon's left hand after instrument exchange. The operative time was 334 min, there was minimal blood loss (15 mL), and the patient's postoperative course was uneventful.
conclusionsRS is a feasible and safe option for patients with SIT undergoing colorectal cancer resection. This case highlights the adaptability of robotic platforms in facilitating unique techniques in the setting of complex anatomical variations. It supports their utility in achieving precise and complication-free oncologic surgery in rare scenarios. Further accumulation of similar patient reports is warranted to establish standardized strategies and validate outcomes.
