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

backgroundOne of the most common acute conditions managed by general surgeons is acute appendicitis. Laparoscopic appendicectomy (LA) is the surgical technique used by many surgeons. The aims of this study were to define our unit's negative appendicectomy rate and compare the outcomes associated with removal of a normal appendix with those for acute appendicitis in patients having LA.

methodsA single-centre retrospective case note review of patients undergoing LA for suspected acute appendicitis was performed. Patients were divided into positive and negative appendicectomy groups based on histology results. The positive group was subdivided into uncomplicated and complicated (perforated and/or gangrenous) appendicitis. Outcomes were compared between groups.

resultsThere were 1413 patients who met inclusion criteria, 904 in the positive group and 509 in the negative group, an overall negative appendicectomy rate of 36.0%. Morbidity rates (6.3% vs. 6.9%; P = 0.48) and types of morbidity were the same for negative appendicectomy and uncomplicated appendicitis. There was no significant difference in complication severity (all P > 0.17) or length of stay (2.3 vs. 2.6 days; P = 0.06) between negative appendicectomy and uncomplicated appendicitis groups. Patients with complicated appendicitis had a significantly higher morbidity rate compared to negative and uncomplicated groups (20.1% vs. 6.3% and 20.1% vs. 6.9%; both P < 0.001).

conclusionThe morbidity of negative LA is the same as LA for uncomplicated appendicitis. The morbidity of LA for complicated appendicitis is significantly higher. The selection criteria for LA in our unit needs to be reviewed to address the high negative appendicectomy rate and avoid unnecessary surgery and its associated morbidity.
