Earlier this week, we reported on the case of Edward Shang, a weight loss surgeon who was forced to retract a study after it became clear that he had enrolled only about a third as many patients as he claimed — if he enrolled any at all. In that post, the editor in chief of Surgery for Obesity and Related Diseases, who retracted the paper, told us he had flagged the issue for Obesity Surgery editors, who had also published Shang’s work.
Yesterday, we heard back from the editor of Obesity Surgery, Scott Shikora, who tells us that he’s reviewed Shang’s four publications in his journal:
- Results of Sleeve Gastrectomy—Data from a Nationwide Survey on Bariatric Surgery in Germany
- A Nationwide Survey on Bariatric Surgery in Germany—Results 2005–2007
- First Experiences with A Circular Stapled Gastro-Jejunostomy by a New Transorally Introducible Stapler System in Laparoscopic Roux-en-Y Gastric Bypass
- Evidence of Thromboembolism Prophylaxis in Bariatric Surgery—Results of a Quality Assurance Trial in Bariatric Surgery in Germany from 2005 to 2007 and Review of the Literature
He was only first author of one of them, however, on circular stapled gastro-jejunostomy. Even there, Shikora said:
We concluded that his role was minimal and there was no need to retract the paper.
Shikora wouldn’t say whether a strongly worded editorial he published last month was about Shang, but said we “can read between the lines.”
