Metachronous colorectal liver metastasis that occurred 10 years after laparoscopic colectomy: a case report.
Article in Surgical case reports, 2022. 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
backgroundDelayed onset of colorectal liver metastasis (CRLM) > 5 years after primary colorectal surgery is rare. Herein, we report a case of delayed-onset CRLM that occurred 10 years after primary surgery, for which laparoscopic hepatectomy was performed. CASE PRESENTATION: A 68-year-old man was admitted to the hospital. His medical history revealed double colon cancer detected 10 years ago, for which laparoscopic colectomy was performed. The pathological tumor-node-metastasis stages were stages I and II. Thereafter, oral floor cancer occurred 7 years after the primary surgery and was curatively resected. The annual follow-up with positron emission tomography-computed tomography (CT) identified a tumor at segment 7/8 (S7/8) of the liver with an abnormal accumulation of fluorodeoxyglucose. Dynamic CT showed a 23-mm tumor, with ring enhancement in the early phase. Magnetic resonance imaging with gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid demonstrated that the tumor had high intensity in T2 weighted sequences and low intensity in the hepatobiliary phase. With a preoperative diagnosis of intrahepatic cholangiocarcinoma or delayed liver metastasis, laparoscopic S7/8 partial resection was performed. The operative time was 324 min, and the intraoperative bleeding volume was 35 mL. The patient was discharged on day 15 without any postoperative complications. Upon histopathological examination, the final diagnosis was CRLM. The patient has survived for 1 year without any recurrence.
conclusionsIt is important to pay attention to the occurrence of delayed-metachronous CRLM.
