External Oblique Intercostal Plane Block Versus Port-Site Infiltration for Laparoscopic Sleeve Gastrectomy: A Randomized Controlled Study.
Trial report in Obesity surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06656299 (Evaluation of Post-Operative Analgesic Efficacy of Bilateral External Oblique Intercostal Plane Block Versus Wound Site Infiltration Control Group in Patients Underwent Laparoscopic Cholecystectomy Surgery), which is not on this map. Cited by 22 papers, 2 of them syntheses that pooled it.
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.

Abstract
purposeAlthough laparoscopic sleeve gastrectomy (LSG) is a minimally invasive surgery, postoperative pain is common. A novel block, the external oblique intercostal (EOI) block, can be used as part of multimodal analgesia for upper abdominal surgeries. The aim of our study is to investigate the effectiveness of EOI block in patients undergoing LSG. MATERIALS AND
methodsSixty patients were assigned into two groups either EOI or port-site infiltration (PSI). The EOI group received ultrasound-guided 30 ml 0.25% bupivacaine, while the PSI group received 5 ml of 0.25% bupivacaine at each port sites by the surgeon. Data on clinical and demographic were collected and analyzed.
resultsThere were no statistical differences in terms of demographic details (p > 0.05). VAS scores were statistically lower during resting at PACU, 1, 2, 4, 8, and 12 h postoperatively in the EOI group than PSI group (p < 0.05), The VAS scores were also lower during active movement at PACU, 1, 2, 4, and 8 h postoperatively in the EOI group than PSI group (p < 0.05). Twenty-four-hour fentanyl consumption was lower in the EOI than in the PSI group (505.83 ± 178.56 vs. 880.83 ± 256.78 μg, respectively, p < 0.001). Rescue analgesia was higher in PSI group than EOI group (26/30 vs. 14/30, respectively, p = 0.001).
conclusionEOI block can be used as a part of multimodal analgesia due to its simplicity and effective postoperative analgesia in LSG.
