Migration of a Hem-O-Lok clip into the cecal lumen following laparoscopic appendectomy: a case report.
Article in BMC gastroenterology, 2026. 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
backgroundHem-O-Lok clips are widely used in laparoscopic appendectomy (LA). Although postoperative clip migration is rare, it is a clinically significant complication. Previous reports have mainly focused on clip migration after cholecystectomy and urologic surgery. To the best of our knowledge, there have been no reports of clip migration into the intestinal lumen after LA. This report suggests that such migration may occur after LA, highlights an important potential device-related complication, and adds to the relevant literature. CASE PRESENTATION: A 44-year-old male experienced persistent dull right lower abdominal pain for three days, two months after LA. Physical examination showed tenderness at McBurney's point, while laboratory tests revealed no abnormalities. The patient had received two Hem-O-Lok clips during surgery two months prior. Abdominal computed tomography (CT) revealed a high-density shadow in the ileocecal region. Colonoscopy confirmed a Hem-O-Lok clip embedded at the appendiceal orifice within the cecal lumen. The patient refused endoscopic removal, opting for conservative observation. At the six-month follow-up, the patient's pain had completely resolved. CLINICAL DISCUSSION: The mechanism of this complication remains unclear and may involve the combined effects of local inflammation and foreign body-related reaction. CT may serve as an initial screening tool, and endoscopy is helpful for establishing the diagnosis. As there is currently no standardized treatment strategy, conservative observation, endoscopic intervention, and surgical treatment may all be considered as options, depending on the individual situation. In clinical practice, attention should also be paid to the standardized use of clips in order to reduce the risk of similar complications.
conclusionThis case highlights the potential risk of Hem-O-Lok clip migration after LA. Clinicians should increase their awareness of this rare complication.
