Enhanced Recovery After Surgery (ERAS) Outcomes After Liver and Pancreas Surgery Based on Regional Perioperative Pain Modalities.
Article in Cureus, 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
introductionON-Q pumps, or surgically placed wound catheters, provide analgesia without the side effects of epidural catheters. This study aimed to evaluate perioperative outcomes, including total postoperative oral morphine milligram equivalents (MMEs), perioperative intravenous (IV) fluid volume, and maximum patient-reported pain scale values, in pancreatic or hepatic resection patients on an Enhanced Recovery After Surgery (ERAS) pathway with ON-Q pumps versus other perioperative pain modalities.
methodsPatients undergoing ERAS protocol pancreatic or hepatic resection at our institution from January 2019 to March 2022 were included. Patients were categorized based on ON-Q pump, epidural, or transversus abdominis plane (TAP) block/local anesthetic. Total postoperative oral morphine milligram equivalents (MMEs), perioperative intravenous (IV) fluid volume, and maximum patient-reported pain scale values were analyzed.
resultsOf 537 included patients, 249 (46%) received an epidural, 116 (22%) received an ON-Q pump, and 172 (32%) received a TAP block/local anesthetic. ON-Q pump patients required significantly less IV fluids (2,933 mL) compared to 3,379 mL for epidural and 3,278 mL for TAP block/local anesthetic patients (p=0.0037). There was no significant difference in MME requirement or pain scores across pain modalities.
conclusionsON-Q pump patients had significantly lower IV fluid requirements, though similar pain scores and MME requirements as epidurals or TAP blocks/local anesthetics. The use of ON-Q pumps as a main perioperative pain modality should be considered for ERAS pathway patients.
