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.

Abstract

backgroundThe open tension-free mesh-plug hernia technique, transabdominal preperitoneal (TAPP) technique, and totally extraperitoneal (TEP) laparoscopic technique all are common surgical procedures for primary unilateral inguinal hernia repair. However, the choice of the right surgical procedure still is controversial in China. This study aimed to compare open tension-free hernioplasty with two laparoscopic hernia repairs.

methodsIn this study, 164 male patients with primary unilateral inguinal hernia were randomized to undergo an open operation with mesh-plug and patch, TAPP, or TEP.

resultsCompletion of the study required 3 years, from February 2006 to February 2009. Of the 164 patients, 62 underwent open repair, 50 had TAPP, and 52 had TEP. The patients then were followed up for 15.6 ± 8.5 months. The average operating time for the open repair group was significantly shorter than for the other two groups (p < 0.001). The cost for the open repair group also was significantly less than for the other two groups (p < 0.001). By contrast, the pain scores in the open mesh group were significantly higher than in the other two groups (p < 0.001). The hospital stay and the recovery time both were significantly longer in open repair group than in the other two groups (p < 0.001). No major complications or recurrence was found in any of the groups.

conclusionsThe findings show that open tension-free mesh-plug hernia repair, TAPP, and TEP are safe and effective for patients with primary unilateral inguinal hernia. Both TAPP and TEP are superior to open repair in terms of less postoperative pain and faster recovery time. The authors therefore recommend laparoscopic repair techniques as the preferable choice of surgical procedure. However, they think open repair will remain a practical solution in China because of its lower cost, short learning period, and need for no special equipment.
