Late-"de novo" paraesophageal hernia after Roux-en-Y gastric bypass (RYGB)-should it be repaired?

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
backgroundThis study presents a case series of "de novo" paraesophageal hernia (dnPEH) in post-Roux-en-Y gastric bypass (RYGB) patients and analyzes the predisposing factors, symptoms, and outcomes after repair. This is a lesser known complication after RYGB and when symptomatic, may warrant surgery.
methodsA retrospective review of data from a single academic institution from 2002 to 2022 was performed identifying patients who developed dnPEH after RYGB and compared them to patients with primary RYGB without post-operative symptomatic dnPEH. Patient characteristics from initial RYGB were analyzed to identify predisposing factors for dnPEH development. Additional information analyzed included time to dnPEH repair, indications for surgery, types of herniation, type of surgical repair, and symptom resolution.
resultsThere were 6975 RYGB in the study period of which 6619 underwent RYGB alone at index surgery, with 31 of those patients developing late stage PEH requiring repair. Patients with older age (51.8 years with dnPEH vs 45.2 years without, p = 0.001) and increased weight loss at 1 year (33.4% vs 30.5%, p = 0.048) from index RYGB were more likely to develop dnPEH. The incidence of dnPEH was 31/6619 (0.47%). Late dnPEH after RYGB took an average of 74 months (45-102 months IQR) to develop symptoms and undergo repair. The most common symptoms were heartburn/reflux 19/31 (61.3%) and epigastric pain 13/31 (41.9%). Symptom resolution rate after repair was highest with 100% for globus and 89.5% heartburn/reflux. The most common form of dnPEH was pouch herniation in 25/31. Surgical repair most commonly included primary cruroplasty alone in 25/31 with additional mesh in 1 case. Recurrence rate was 2/31 (6.54%).
conclusionLate dnPEH after RYGB is an emerging entity typically occurring years after index RYGB. Symptomatic patients with dnPEH warrant hernia repair and responded well to surgical repair in this case series.
