Banded Gastric Bypass: Better Long-Term Results? A Cohort Study with Minimum 5-Year Follow-Up.
Article in Obesity surgery, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 41 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
backgroundWhile gastric bypass has been the treatment of choice for morbid obesity, insufficient weight loss and even weight regain has been observed in a sub-group of patients. Dilatation of the pouch, pouch outlet, and proximal alimentary limb have been suggested to cause weight regain on the long term. The banded gastric bypass surgery has been introduced to overcome this problem.
methodsFour hundred thirty-two patients (n = 254, non-banded/n = 178, banded-GaBP Ring™) were followed-up for 5 years. Patients were evaluated for weight loss, % excess weight loss (%EWL), weight regain and BMI.
resultsNo significant differences between groups in the first year following surgery were observed in terms of weight loss and %EWL. %EWL at 5 years was as follows: non-banded 65.2 ± 20.0 %; banded 74.0 ± 15.1 %. At 5 years, the banded group showed more weight loss (non-banded 35.4 ± 12.5; banded 43.9 ± 11.9 kg, P < 0.0001); weight regain was significantly higher in the non-banded group (P < 0.0001). Only minor complications were reported; no signs of ring migration or slippage were reported.
conclusionAlthough, following the first year after surgery, no differences in treatment groups were observed in terms of weight loss, 5 years following surgery, patients who received banded surgery maintained better weight loss and had less weight regain compared to the non-banded group. These results suggest that laparoscopic banded gastric bypass using a silastic ring was effective in maintaining weight loss on the long term, while the complication rate was low. The banded gastric bypass is regarded by us as the new gold standard.
