Incisional Hernia Rates After Laparoscopic or Open Abdominal Surgery-A Systematic Review and Meta-Analysis.

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
backgroundIncisional hernias are one of the most common long-term complications associated with open abdominal surgery. The aim of this review and meta-analysis was to systematically assess laparoscopic versus open abdominal surgery as a general surgical strategy in all available indications in terms of incisional hernia occurrence.
methodsA systematic literature search was performed to identify randomized controlled trials comparing incisional hernia rates after laparoscopic versus open abdominal surgery in all indications. Random effects meta-analyses were calculated and presented as risk differences (RD) with their corresponding 95 % confidence intervals (CI).
results24 trials (3490 patients) were included. Incisional hernias were significantly reduced in the laparoscopic group (RD -0.06, 95 % CI [-0.09, -0.03], p = 0.0002, I (2) = 75). The advantage of the laparoscopic procedure persisted in the subgroup of total-laparoscopic interventions (RD -0.14, 95 % CI [-0.22, -0.06], p = 0.001, I (2) = 87 %), whereas laparoscopically assisted procedures did not show a significant reduction of incisional hernias compared to open surgery (RD -0.01, 95 % CI [-0.03, 0.01], p = 0.31, I (2) = 35 %). Wound infections were significantly reduced in the laparoscopic group (RD -0.06, 95 % CI [-0.09, -0.03], p < 0.0001, I (2) = 35 %); overall postoperative morbidity was comparable in both groups (RD -0.06, 95 % CI [-0.13, 0.00], p = 0.06; I (2) = 64 %). Open abdominal surgery showed a significantly longer hospital stay compared to laparoscopy (RD -1.92, 95 % CI [-2.67, -1.17], p < 0.00001, I (2) = 87 %). At short-term follow-up, quality of life was in favor of laparoscopy.
conclusionsIncisional hernias are less frequent using the total-laparoscopic approach instead of open abdominal surgery. Whenever possible, the less traumatic access should be chosen.
