Surgical recurrence less frequent with laparoscopic surgery for Crohn disease

Laparoscopic Crohn Surgery Linked to Lower Reoperation Risk

A retrospective study followed 641 Crohn disease surgery patients for a mean of 12.4 years.
Laparoscopy was associated with lower cumulative surgical recurrence than open surgery.
Open surgery, smoking, female sex and inflamed microscopic margins were associated with increased recurrence risk.
The authors caution that the observational design cannot prove causation.

Melatonin and Ambien before surgery may improve sleep, reduce pain and opioid use after surgery

Pre-Surgery Sleep May Reduce Pain and Opioid Use

The review assessed 16 studies with more than 1,100 patients.
It focused on melatonin or zolpidem used before, rather than after, surgery.
Melatonin was associated with less anxiety, pain and inflammation across reviewed studies.
Some abdominal-surgery studies found opioid use fell by more than 30%.

GLP-1 drugs linked to lower risk of serious heart-related complications and infections after surgery

GLP-1 Use Tied to Fewer Complications After Surgery

Analysis included more than 2 million adults undergoing elective surgery.
GLP-1 use was associated with lower odds of major cardiovascular complications and infections.
Researchers cautioned that the observational analysis cannot prove the drugs caused the benefit.

Cannabis use linked to higher heart attack risk during and after surgery, but fewer blood clots

Cannabis Use Tied to Higher Perioperative Heart Attack Risk

A five-study review of 44,312 patients associated cannabis use with a 46% higher perioperative heart-attack risk.
The review found no significant association with stroke, respiratory failure, kidney injury or death.
The authors said an observed lower venous-clot risk does not establish cannabis as protective.

Wearing headphones during surgery may reduce nausea and vomiting afterward

Noise-Canceling Headphones Linked to Less Post-Surgery Nausea

A 192-person randomized trial tested headphones during minimally invasive gynecological surgery.
PONV occurred in 35.4% of headphone users versus 52.1% of controls within 48 hours.
The finding was presented at Anesthesiology 2026 and requires further study.

AA: Pulmonary aspiration, regurgitation under anesthesia more likely with GLP-1 RAs

GLP-1 RAs Linked to 11-Fold Higher Odds of Aspiration Under Anesthesia

A UK national prospective multicenter cohort study published online Sept. 16 in Anaesthesia examined perioperative GLP-1 RA use and outcomes, timed to the Association of Anaesthetists annual meeting in Liverpool, Sept. 16–18.
The study, led by Thomas E. Potter, M.B.B.S., of Guy's and St Thomas' NHS Foundation Trust, covered 47,039 patients at 119 UK sites; 2.9 percent reported receiving GLP-1 RAs.
Incidence of pulmonary aspiration and/or regurgitation was 1.41 percent in the GLP-1 RA cohort versus 0.12 percent in the non-GLP-1 RA cohort, an odds ratio of 11.39.
Among patients taking GLP-1 RAs, these events occurred most often during emergence from anesthesia.

Leadership helps reduce stress in operating rooms

OR Leadership Shapes Team Stress, Study Finds

Leiden researchers observed 100 hours of surgeries and interviewed 32 health care professionals.
The study examined stress from surgical complications, teamwork and organizational pressures.
Researchers say surgeons’ behavior can raise or lower stress across the entire operating room team.
The findings point to stronger briefings and reflection after surgery as practical leadership tools.

Call for systematic bone health optimization before joint replacement and spinal fusion surgery

Bone Health Gets a Larger Role in Joint and Spine Surgery

The International Osteoporosis Foundation urges systematic osteoporosis care around joint replacement and spinal fusion.
The paper links weak bone to a shared endpoint it calls implant fixation failure.
Authors argue bone quality should be treated as a determinant of surgical durability, not only fracture risk.
