Impact on postoperative complications of changes in skeletal muscle mass during neoadjuvant chemotherapy for gastro‐oesophageal cancer

BJS Open, Volume 4, Issue 5, Page 847-854, October 2020., 2020
Deconditioning during neoadjuvant chemotherapy is a possible parameter for predicting operative outcomes. This retrospective cohort study aimed to assess body composition changes in patients with gastro‐oesophageal cancer during neoadjuvant therapy and investigate their association with postoperative complications. Skeletal muscle index values decrease

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.

Peritoneal bridging versus fascial closure in laparoscopic intraperitoneal onlay ventral hernia mesh repair: a randomized clinical trial

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 ...

Total tumour volume as a prognostic factor in patients with resectable colorectal cancer liver metastases

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.

Prediction of a positive circumferential resection margin at surgery following neoadjuvant chemotherapy for adenocarcinoma of the oesophagus

BJS Open, Volume 3, Issue 6, Page 767-776, December 2019., 2019
A positive circumferential resection margin (CRM) has been shown to be an adverse prognostic indicator after oesophagectomy for adenocarcinoma. Clinical tumour status, tumour volume, poor differentiation, lack of response following chemotherapy and radiological assessment of invasion can be used to predict CRM positivity in oesophageal adenocarcinoma ...
