1 · What the graph read from 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.

2 · The registry

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

backgroundAdrenalectomy can be performed via open and various minimally invasive approaches. The aim of this systematic review was to summarize the current evidence on surgical techniques of adrenalectomy.

methodsSystematic literature searches (MEDLINE, EMBASE, Web of Science, Cochrane Library) were conducted to identify randomized controlled trials (RCTs) and controlled clinical trials (CCTs) comparing at least two surgical procedures for adrenalectomy. Statistical analyses were performed, and meta-analyses were conducted. Furthermore, an indirect comparison of RCTs and a network meta-analysis of CCTs were carried out for each outcome.

resultsTwenty-six trials (1710 patients) were included. Postoperative complication rates did not show differences for open and minimally invasive techniques. Operation time was significantly shorter for open adrenalectomy than for the robotic approach (p < 0.001). No differences were found between laparoscopic and robotic approaches. Network meta-analysis showed open adrenalectomy to be the fastest technique. Blood loss was significantly reduced in the robotic arm compared with open and laparoscopic adrenalectomy (p = 0.01). Length of hospital stay (LOS) was significantly lower after conventional laparoscopy than open adrenalectomy in CCTs (p < 0.001). Furthermore, both retroperitoneoscopic (p < 0.001) and robotic access (p < 0.001) led to another significant reduction of LOS compared with conventional laparoscopy. This difference was not consistent in RCTs. Network meta-analysis revealed the lowest LOS after retroperitoneoscopic adrenalectomy.

conclusionMinimally invasive adrenalectomy is safe and should be preferred over open adrenalectomy due to shorter LOS, lower blood loss, and equivalent complication rates. The retroperitoneoscopic access features the shortest LOS and operating time. Further high-quality RCTs are warranted, especially to compare the posterior retroperitoneoscopic and the transperitoneal robotic approach.
