Laparoscopic-Guided Transversus Abdominis Plane (TAP) Block Combined with Port-Site Infiltration (PSI) for Laparoscopic Sleeve Gastrectomy in an ERABS Pathway: A Randomized, Prospective, Double-Blind, Placebo-Controlled Trial.
Trial report in Obesity surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposePatients undergoing laparoscopic sleeve gastrectomy (LSG) commonly experience moderate to severe postoperative pain. We conducted a randomized, prospective double-blind placebo-controlled study to evaluate the analgesic effect of laparoscopic-guided TAP (LG-TAP) block after LSG in a high-volume bariatric center, applying an enhanced recovery after bariatric surgery (ERABS) pathway. MATERIAL AND
methodsOne hundred ten patients were randomly allocated to receive LG-TAP block with local anesthetic (LA) or saline solution (placebo), both combined with port-site infiltration with LA (LA-PSI). Primary outcome was pain score measured in post-anesthesia care unit (PACU) and at 6, 12, and 24 h after surgery. Secondary outcomes included postoperative nausea and/or vomiting (PONV), analgesic requirement, time to walking, time to flatus, length of hospital stay (LOS), and surgical complications.
resultsNo significant differences were observed between LG-TAP and placebo groups in postoperative analgesia, with a median (IQR) NRS of 2 (4.75-0) vs. 2 (5.25-0) in PACU, 5.5 (7-3) vs. 6 (7-4) at 6 h, 2 (6-0) vs. 3 (5.25-1.75) at 12 h, and 2 (3.75-0) vs. 1 (2-0) at 24 h; all p > 0.05. A significant difference was found in PONV in PACU (LG-TAP, 46%; placebo, 25%, p-value, 0.019) and at 6 h postoperatively (LG-TAP, 69%, placebo, 41%, p-value, 0.003). No differences were observed as regards other secondary outcomes.
conclusionOur results suggest that LG-TAP block is not related to more effective postoperative analgesia compared to placebo when LA-PSI is performed.
