Trial reportSurgical endoscopy2021
A prospective randomised control trial to compare the perioperative outcomes and ergonomic challenges between triangular versus midline port placement in total extra-peritoneal repair of uncomplicated unilateral inguinal hernia.
Trial report in Surgical endoscopy, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
backgroundRoutine TEP technique requires three skin incisions for placement of three trocars in the midline. Otherwise, this can be done by three-port triangular technique or two-hand technique. This study reports a randomised trial of perioperative outcomes and ergonomics characteristics of this procedure using two different techniques of port insertion.
methodsN = 28 patients were randomised into two groups for triangular three-port (TTEP) versus midline three-port TEP (MTEP) hernioplasty after informed written consent in Department of Surgery, King George's Medical University UP between September 2016 and September 2017 after institutional ethical approval. Patient-related outcomes in terms of quality of life (QOL) and ergonomic evaluation of the technique were compared in double-blinded fashion.
resultsPostoperative pain score at 24 h post surgery (5.1 ± 0.6; 95% CI 4.9-5.3 vs. 4.8 ± 0.4; 95% CI 4.6-4.9) differed, while hospital stay, time to return to routine work, tolerance to oral feeds and intraoperative complications occurrence (OR 2.1; 95% CI 0.2-24.3) were comparable in both groups. Time to return to office work (5.5 ± 0.5; 95% CI 5.4-5.7 vs. 4.0 ± 0.8; 95% CI 3.7-4.3) and immediate postoperative sensation of mesh and pain score were significantly higher in MTEP compared to TTEP. Ergonomic parameters including visualization of landmark score, spreading of mesh score and total surgeon satisfaction score (TTEP 8.4 ± 0.7; 95% CI 8.1-8.6 vs. MTEP 7.0 ± 0.8; 95% CI 6.7-7.3), mental effort quotient (SMEQ score: TTEP 50.6 ± 12.7; 95% CI 45.9-55.3 vs. MTEP 70.8 ± 12.6: 95% CI 66.1-75.4) and physical effort quotient (LEDQ scores in wrist, hand, arm and shoulders) were also superior in triangular technique of port placement.
conclusionTriangular three-port TEP hernioplasty is ergonomically feasible and enables a surgeon to perform surgery safely using basic principles of laparoscopy.
