Comparison of Posterior Quadratus Lumborum Block vs Surgical Wound Infiltration in Patients Undergoing Bariatric Sleeve Gastrectomy Surgery.
Trial report in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis 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
backgroundWe are studying whether the performance of the posterior quadratus lumborum block (pQLB) will decrease postoperative opioid consumption in patients undergoing laparoscopic sleeve gastrectomy (LSG) compared with surgical wound infiltration with local anesthetic.
methodsThis is a single-center, prospective, randomized pilot study. Forty ASA 3 patients with severe obesity undergoing LSG were randomized to receive either the pQLB or surgical wound infiltration of local anesthetics. Major endpoints included postoperative analgesic medications in the pQLB group versus the surgical wound infiltration group, visual analog pain scores (VAS 0-10), postoperative time to first opioid, and incidence of nausea and vomiting.
resultsOpioid consumption in morphine equivalents on postoperative days 1 (p = 0.86) and 2 (p = 0.57) was not significantly different between the two groups. However, patients in the pQLB group had significantly lower VAS pain scores on postoperative day 1 (p = 0.003) and postoperative day 2 (p = 0.04) than those who received surgical wound infiltration.
conclusionsThis prospective, randomized pilot study shows that the performance of pQLB did not reduce postoperative opioid consumption in patients undergoing LSG. However, patients who received the pQLB had significantly lower postoperative VAS pain scores. Therefore, the performance of pQLB is both feasible and may provide analgesic benefits in patients undergoing LSG.
