Multiloculated Klebsiella liver abscess successfully treated with early laparoscopic drainage after failed percutaneous drainage: a case report.

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
Background: Klebsiella pneumoniae liver abscess is characterized by an aggressive clinical course with a high risk of metastatic complications. Early initiation of appropriate antibiotics and timely drainage are essential for successful management. However, large multiloculated Klebsiella pneumoniae liver abscesses are associated with a high risk of percutaneous drainage failure. Case Description: A 70-year-old man with a history of prediabetes and chronic kidney disease presented with a 2-week history of progressively worsening right upper quadrant abdominal pain. On presentation, he was tachycardic at 107 beats per minute. Physical examination revealed marked right upper quadrant tenderness and hepatic percussion tenderness. Laboratory testing demonstrated neutrophil-predominant leukocytosis and elevated alkaline phosphatase and gamma-glutamyl transferase levels. Contrast-enhanced abdominal computed tomography (CT) revealed an 11-cm multiloculated mass in the right hepatic lobe consistent with a liver abscess. Intravenous ceftriaxone and metronidazole were initiated, and percutaneous drainage was performed. Culture of the aspirated fluid grew Klebsiella pneumoniae. Despite percutaneous drainage, the patient continued to experience severe pain and persistent leukocytosis, and follow-up CT demonstrated a persistent hepatic abscess. He subsequently underwent laparoscopic partial liver resection with fenestration of the abscess cavity. Postoperative imaging showed marked improvement, with resolution of symptoms and leukocytosis. Conclusions: This case underscores the importance of carefully evaluating morphology and causative organism of abscess when selecting a drainage strategy for pyogenic liver abscess. In patients with multiloculated Klebsiella pneumoniae liver abscess, clinicians should maintain a low threshold for considering early surgical drainage.
