Diagnostic accuracy of acute diverticulitis with unenhanced low‐dose CT
BJS Open, Volume 4, Issue 4, Page 659-665, August 2020., 2020 Unenhanced low‐dose CT (LDCT) is as accurate as contrast‐enhanced standard‐dose CT (SDCT) for detection of acute colonic diverticulitis. However, smaller complications, such as pericolic abscesses and small amounts of extraluminal air, can be missed.

BJS Open, Volume 4, Issue 4, Page 587-592, August 2020., 2020 Fifty patients were enrolled and randomized to laparoscopic hernia repair with conventional fascial closure or a peritoneal bridging approach. Follow‐up by CT at 12 months (primary endpoint) revealed no seroma in either group, but seroma was detected clinically in the early postoperative period after 1 month (4 of 25 versus 0 of 25 patients in fascial ...

BJS Open, Volume 4, Issue 3, Page 456-466, June 2020., 2020 This study investigated whether the total tumour volume (TTV) of colorectal liver metastases could predict patient survival after hepatic resection. Associations were identified between TTV and recurrence‐free survival, overall survival and unresectable recurrence after primary hepatic resection.

Factors affecting mortality after traumatic brain injury in a resource‐poor setting
BJS Open, Volume 4, Issue 2, Page 320-325, April 2020., 2020 Traumatic brain injury (TBI) in 194 patients in a resource‐poor setting was analysed. Some 30·9 per cent had severe TBI, and associated skull fracture was observed in 8·8 per cent. Treatments offered were mainly conservative. The mortality rate was 33·0 per cent, with 72 per cent resulting from severe head injury.
