Epigastric port retrieval of the gallbladder following laparoscopic cholecystectomy is associated with the reduced risk of port site infection and port site incisional hernia: An updated meta-analysis of randomized controlled trials.
Review in Annals of medicine and surgery (2012), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06953713 (Umbilical Trochar Site Is The Usual Suspect For Trocar Hernia After Laparoscopic Cholecystectomy), which is not on this map. Cited by 6 papers.
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.

Abstract
aimsThe objective of this article is to compare the surgical outcomes for epigastric port or umbilical port retrieval of the gallbladder (GB) following laparoscopic cholecystectomy (LC).
methodsThe data retrieved from the published randomized, controlled trials (RCT) comparing the surgical outcomes for epigastric port or umbilical port retrieval of the GB following LC was analysed using the principles of meta-analysis. The summated outcome of continuous variables was expressed as standardized mean difference (SMD) and dichotomous data was presented in odds ratio (OR).
resultsEight RCTs on 2676 patients comparing the surgical outcomes for epigastric port or umbilical port retrieval of the GB following LC were analysed. In the random effects model analysis using the statistical software Review Manager 5.3, the GB retrieval through epigastric port was associated with the reduced duration of operation (SMD, 0.41; 95% CI, 0.18, 0.64; z = 3.52; P = 0.0004). Epigastric retrieval was also associated with reduced risk of surgical site infection (OR, 1.95; 95% CI, 0.75, 5.11; z = 1.36; P = 0.17), and port site incisional hernia (OR, 4.22; 95% CI, 0.43, 41.40; z = 1.24; P = 0.22) compared to umbilical port retrieval though it did not reach statistical significance. The need for port enlargement to retrieve the GB was similar in both groups. In contrast, the umbilical port retrieval of the GB was associated with significantly less post-operative pain (SMD, -0.51; 95% CI, -0.95, -0.06; z = 2.24; P = 0.03), reduced GB perforation rate, reduced port site bleeding rate and reduced difficulty in GB retrieval.
conclusionGB retrieval through epigastric port following LC has clinically proven advantage of reduced retrieval site infection rate, lower operation time and incisional hernia rate but at the cost of increased pain at 24 h, higher risk of GB perforation, port site bleeding and technical difficulties.
