Comparative perioperative outcomes of articulated versus conventional straight devices in single-port totally extraperitoneal inguinal hernia repair: A propensity score-matched analysis.
Article in Surgical endoscopy, 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
backgroundSingle-port totally extraperitoneal (TEP) inguinal hernia repair offers enhanced cosmetic outcomes and reduced port-related morbidity but is technically demanding with conventional straight laparoscopic instruments. Articulated instruments such as ArtiSential® were developed to improve ergonomics and dexterity. This study compared perioperative and postoperative outcomes of single-port TEP inguinal hernia repair performed with articulated instruments versus conventional straight devices.
methodsBetween March 2023 and September 2024, 584 consecutive patients underwent single-port TEP inguinal hernia repair at a single tertiary institution. Conventional straight instruments were used in 443 patients, and ArtiSential® articulated instruments in 141 patients. Propensity score matching (PSM) was performed in a 1:1 ratio based on predefined demographic and clinical variables, resulting in 141 patients in each group. Perioperative outcomes and postoperative complications were compared.
resultsAfter PSM, baseline characteristics were well balanced between the two groups. Median operative time was significantly longer in the conventional group than in the ArtiSential® group (40.0 min [interquartile range (IQR) 30.0-55.0] vs. 35.0 min [IQR 25.0-50.0]; P = 0.034). No conversions to open or transabdominal preperitoneal repair occurred. A standardized 10 × 15 cm mesh was used in all cases. Length of hospital stay, overall complication rate, and specific postoperative complications, including urinary retention, seroma, skin bleeding, fever, chronic pain, and early recurrence, were comparable between groups. No major complications (Clavien-Dindo grade III-IV), readmissions, reoperations, or recurrences were observed during the study period.
conclusionsIn single-port TEP inguinal hernia repair, the use of articulated instruments was associated with a significantly shorter operative time compared with conventional straight devices, while maintaining equivalent perioperative safety and early postoperative outcomes. Articulated instruments may enhance efficiency and ergonomics in minimally invasive inguinal hernia surgery, including complex cases. Long-term oncologic and functional outcomes, ergonomic assessment, and cost-effectiveness warrant further investigation.
