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

purposeComplicated acute appendicitis is still associated with an increased morbidity. If laparoscopy has been accepted as a valid approach, some questions remain concerning intra-abdominal abscess formation. Routine prophylactic drainage of the abdomen has been proposed. However, this practice remains a matter of debate, poorly validated in the literature. With the present study, we investigated the impact of drainage in laparoscopic appendectomy for complicated appendicitis.

methodThis is a case match study of consecutive patients operated on by laparoscopy in a single institution. One hundred and thirty patients operated for complicated appendicitis (local peritonitis without perforation, with perforation, or with periappendicular abscess) with prophylactic intraperitoneal drainage were matched one by one to 130 patients operated without drainage. Uncomplicated appendicitis and generalized peritonitis were excluded. Primary endpoint was surgical complications and secondary endpoints were transit recovery time and length of hospital stay.

resultsPatients without drain had significantly less overall complications (7.7% vs. 18.5%, p = 0.01). Moreover, the absence of drainage was of significant benefit for transit recovery time (2.5 vs. 3.5 days, p = 0.0068) and length of hospital stay (4.2 vs. 7.3 days, p < 0.0001).

conclusionNo benefits were observed for prophylactic drainage of the abdominal cavity during emergency laparoscopic treatment of complicated appendicitis. For this reason, this practice may be abandoned.
