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

backgroundLaparoscopic inguinal hernia repair utilizes either a transabdominal preperitoneal (TAPP) or totally extraperitoneal (TEP) approach. The literature remains mixed on outcomes comparing TAPP versus TEP. The objective of our study was to assess outcomes, healthcare utilization, and cost differences between TAPP and TEP inguinal hernia repair.

methodsAdult patients who underwent elective inguinal hernia repair between 2013 and 2021 were retrospectively identified from our institution's electronic health record. Baseline characteristics and postoperative complications were compared using chi-squared test. Multivariable logistic regression was used to model the odds of experiencing a postoperative emergency department visit, readmission, and/or reoperation within 6 months were surgery. Generalized linear models were used to investigate differences in cost between TAPP and TEP groups.

results1086 patients underwent TAPP repair, while 1277 patients underwent TEP repair. TAPP patients had more than double the rates of readmissions (3.1% vs. 1.3%, p = 0.002) and reoperations (1.5% vs. 0.2%, p = 0.001) within 6 months of surgery. On multivariable analysis, undergoing TAPP inguinal hernia repair was associated with higher odds of reoperations and/or readmissions within 6 months of surgery (OR 2.8, CI [1.5, 5.1], p = 0.001). TAPP repair had a higher index surgery cost and higher costs associated with reoperations and readmissions compared to TEP repair.

conclusionAlthough both approaches are very safe, TAPP inguinal hernia repair had higher rates of postoperative complications, increased healthcare utilization, and higher associated costs. Future studies should be directed toward decreasing postoperative healthcare utilization in order to decrease costs in inguinal hernia repair.
