A comparative study of retroperitoneal laparoscopic adrenalectomy via intra and extra perinephric fat approaches.

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
objectiveTo investigate the safety and effectiveness of retroperitoneal adrenalectomy via extra and intra perinephric fat approaches to provide experience and basis for resection of adrenal tumors through the retroperitoneal cavity.
methodsThe clinical data of 284 patients undergoing retroperitoneal adrenalectomy in our hospital from December 2017 to March 2023 were collected. The basic characteristics of the two groups of patients and the changes in perioperative indicators were retrospectively analyzed.
resultsA total of 117 patients with intra perinephric fat approach (IPFA) were included,and 167 patients with extra perinephric fat approach (EPFA) were included. The estimated blood loss in the IPFA group (123.59 ± 50.76 ml) was higher than that in the EPFA group (99.10 ± 99.51 ml) (p = 0.015),and the operative time in the IPFA group(105.25 ± 42.25 min) was longer than that in the EPFA group(81.75 ± 30.45 min) (p < 0.001).The hospitalization expenses of IPFA patients (36,306.39 ± 7544.25RMB) were higher compared with patients receiving EPFA (32,122.77 ± 7284.00RMB) (p < 0.001).There were no significant differences between the two groups in terms of tumor size,blood transfusion times and postoperative hospitalization time.
conclusionRetroperitoneal laparoscopic adrenalectomy is a safe and effective procedure that can be performed via extra and intra perinephric fat approaches.IPFA is associated with higher estimated blood loss, and the operation time of EPFA is shorter than IPFA. The choice of surgical approach may depend primarily on the experience of the surgeon, the characteristics of adrenal tumor, and the nature of perirenal adipose tissue.
