Unrecognized pregnancy prior to bariatric surgery: case report and review of implications
Bibliographic record
Abstract
Summary A substantial proportion of patients undergoing bariatric surgery are female and of reproductive age. Guidelines suggest that pregnancy should be avoided for 12–18 months following bariatric surgery, and that women be appropriately counselled regarding contraception. We present a case in which a patient underwent a Roux‐en Y gastric bypass while unknowingly in the early stages of pregnancy. After a six‐week period liquid meal replacement for perioperative weight loss, a laparoscopic Roux‐en Y gastric bypass, and a short course of oral antibiotics for a post‐operative wound infection, the patient developed epigastric pain, odynophagia, oesophageal dysphagia, bloating and nausea with oral intake. Only after an abdominal X‐ray, two upper endoscopies and an upper gastrointestinal series was an intrauterine pregnancy seen incidentally on abdominal ultrasound. Ultimately, the patient underwent elective termination of her pregnancy. Patients who are, or are planning to soon become, pregnant should not undergo bariatric surgery. All female patients of reproductive age should be counselled on the importance of effective birth control prior to planning bariatric surgery. Beta‐human chorionic gonadotropin testing should be routinely considered before embarking on meal replacement or surgery.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
