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

purposeThe hypothesis of this meta-analysis was to assess whether laparoscopic approach shows real benefits over Lichtenstein technique in recurrent inguinal hernia repair.

methodsA literature search for prospective randomized trials comparing laparoscopic and Lichtenstein procedure in recurrent inguinal hernia repair was performed. Trials were reviewed for primary outcome measures: re-recurrence, chronic inguinal pain and ischemic orchitis; and for secondary outcome measures. Standardized mean difference (SMD) was calculated for continuous variables and odds ratio for dichotomous variables.

resultsSeven studies comparing laparoscopic and Lichtenstein technique were considered suitable for the pooled analysis. Overall 647 patients with recurrent inguinal hernia were randomized to either laparoscopic repair (333, 51.5 %, transabdominal preperitoneal approach, TAPP and totally extraperitoneal approach, TEP) or anterior open repair (314, 48.5 %, Lichtenstein operation). Patients who underwent laparoscopic repair experienced significantly less chronic pain (9.2 % vs. 21.5 %, p = 0.003). Patients of the laparoscopic group had a significantly earlier return to normal daily activities (13.9 vs. 18.4 days, SMD = -0.68, 95 % CI = -0.94 to -0.43, p < 0.000001). Operative time was significantly longer in laparoscopic operations (62.9 vs. 54.2 min, SMD 0.46, 95 % CI 0.03, 0.89; p = 0.04). No other differences were found.

conclusionsLaparoscopy showed reduced chronic inguinal pain and an earlier return to normal daily activities but significantly longer operative time. Despite the expected advantages, the choice between laparoscopy and other techniques still depends on local expertise availability. Only dedicated centers are able to routinely offer laparoscopy for recurrent inguinal hernia repair.
