Smoking linked to weaker rectal cancer response
Patients smoking at diagnosis were less likely to have a favorable response to treatment before rectal cancer surgery; former smokers were not.

Subtotal colectomy matches total for constipation
For severe slow-transit constipation, removing less colon gave similar symptom relief at one year, with less early incontinence.
Fewer wound problems linked to transanal extraction
In low rectal cancer surgery, removing the specimen through the anus was linked to fewer wound complications and less pain in the first two days.
Technical difficulty did not worsen TaTME cancer outcomes
In this 210-patient multicenter cohort, higher technical difficulty during TaTME prolonged operating time but was not associated with worse recurrence or survival outcomes.
Diverticulitis guideline favors surgery after abscess
A new multi-society guideline suggests elective resection for patients with persistent symptoms after recurrent uncomplicated diverticulitis and for those recovering from a first diverticular abscess—but these are conditional recommendations, not mandates.
Single-port robotics is feasible in colorectal surgery
A SAGES task-force review finds the single-port platform can support selected colorectal operations, but offers technical guidance—not evidence of better patient outcomes.
Delayed rectal surgery linked to worse outcomes
In this Swedish cohort, rectal cancer surgery 28–90 days after short-course radiotherapy was associated with more recurrence, metastasis, and worse overall survival than surgery within 7 days.
Intracorporeal Right Colectomy, Fewer Site Hernias
After laparoscopic right colectomy for cancer, an institutional shift to intracorporeal anastomosis was associated with fewer extraction-site hernias and no detectable increase in complications.
CT Distention Flags Risk in Obstructing Colon Cancer
In left-sided obstructing colon cancer, cecal dilation ≥9 cm plus small-bowel distention on CT identified patients with worse outcomes after emergency resection—and may help guide consideration of bridge-to-surgery.
POD2 CRP identifies low leak risk after colon resection
After elective colon cancer resection, POD2 CRP below 100 mg/L identified patients with about a 1% risk of major anastomotic leak—potentially supporting earlier discharge.
