Comparative Outcomes of Transabdominal Preperitoneal and Totally Extraperitoneal Laparoscopic Inguinal Hernia Repair: A Retrospective Cohort Study.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionLaparoscopic inguinal hernia repair is widely performed using either the transabdominal preperitoneal (TAPP) or totally extraperitoneal (TEP) approach. Although both techniques are established, uncertainty persists regarding their relative perioperative and postoperative outcomes in routine clinical practice. The aim of the present study was to compare operative parameters, postoperative recovery, complication rates, and short-term outcomes between TAPP and TEP laparoscopic inguinal hernia repair. MATERIALS AND
methodsThis retrospective cohort study included 100 adult patients who underwent elective laparoscopic inguinal hernia repair between August 2021 and April 2023. Patients were equally divided into TAPP (n = 50) and TEP (n = 50) groups. Demographic characteristics, operative details, postoperative pain, length of hospital stay, intraoperative conversion, complications, and follow-up outcomes were analyzed. Continuous variables were compared using independent samples t-tests, and categorical variables were analyzed using Fisher's exact or chi-squared tests.
resultsBaseline demographic and hernia-related characteristics were comparable between the groups. A significantly higher intraoperative conversion rate was observed in the TEP group. Operative time, postoperative pain scores, and hospital stay did not differ significantly between techniques. Rates of short-term complications, including seroma, infection, and urinary retention, were similar. Short-term outcomes, including recurrence and chronic groin pain, showed no statistically significant differences during follow-up.
conclusionBoth TAPP and TEP laparoscopic inguinal hernia repairs demonstrated comparable safety and effectiveness. However, the higher conversion rate associated with TEP highlights its technical complexity. Technique selection should be guided by surgeon experience, patient factors, and institutional expertise.
