A randomized study on laparoscopic total extraperitoneal inguinal hernia repair with hernia sac transection vs complete sac reduction.

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.
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
objectiveThe management of the hernia sac is the core step of laparoscopic indirect inguinal hernioplasty. In this study, a randomized controlled trial was conducted to evaluate the clinical effect of laparoscopic total extraperitoneal inguinal herniorrhaphy (TEP) with hernia sac transection and complete sac reduction.
methodFrom May 2017 to May 2018, 70 patients aged 18-75 with primary indirect inguinal hernia in our hospital were randomly divided into a transected sac group (TS) and a completely reduced sac group (RS). The primary outcomes compared between the two groups were the hernia sac treatment time, operation time, and the incidence of seroma formation after operation. Secondary outcomes included acute pain, chronic pain (pain which lasted for at least 3 months), hospital stay, recurrence rate, and other complications.
resultThere were no significant differences in baseline demographic characteristics including age, sex, hernia type, size of hernia defect, and follow-up time between the two groups. The times required for hernia sac separation and operation in the TS group were significantly shorter than in the control group (6.1 ± 2.3 vs. 25 ± 5.8 min for hernia sac separation, p < 0.01; and 35.10 ± 3.50 vs. 54.40 ± 4.20 min for operation, p < 0.01). There was no significant difference in hospitalization time, incidence of acute pain, seroma formation, or urinary retention between the two groups. During the 12-month follow-up period, chronic pain, early recurrence, and other complications were not found in either group.
conclusionBoth the hernia sac transection technique and the complete sac reduction technique are safe and reliable. The hernia sac transection technique is a simple and effective hernia sac treatment method. It reduces the operation time and does not increase seroma or acute or chronic pain. It is valuable and likely to be popularly applied.
