More general surgery trends
All specialties →Neoadjuvant therapy in pancreatic cancer
Chemotherapy or chemoradiation before surgery for pancreatic cancer.
Key point: After induction chemotherapy, neoadjuvant chemoradiotherapy is used for borderline tumours to increase chances of complete resection, though survival benefit has not been demonstrated.
Antibiotics for appendicitis
Treating uncomplicated appendicitis with antibiotics instead of surgery.
Key point: Non-operative management of acute uncomplicated appendicitis was associated with high long-term failure rates and significant risk of subsequent appendectomy.
ICG fluorescence-guided surgery
Indocyanine green imaging during surgery to assess perfusion and anatomy.
Key point: FIGS with ICG is recommended for detecting non-regional metastases, identifying primary cancers and GI cancer lymph nodes, and assessing esophageal and left-sided colorectal anastomosis quality.
Organ preservation in rectal cancer
Total neoadjuvant therapy and watch-and-wait approaches for rectal cancer.
Key point: A higher radiation boost dose was not significantly associated with achieving clinical complete response or durability of organ preservation after total neoadjuvant therapy.
Surgical site infection prevention
Measures to prevent infections after surgery.
Mesh in ventral hernia repair
Mesh choice and technique in ventral and incisional hernia repair.

How these numbers are counted
PubMed query, searched in titles and abstracts by publication date:
"bariatric surgery"[tiab] OR "metabolic surgery"[tiab] OR "sleeve gastrectomy"[tiab]Trials: ClinicalTrials.gov studies first submitted in each 12-month window that match the same terms. A query can miss synonyms or catch unrelated papers, so treat counts as approximate.
