Tumour growth rate of carcinoma of the colon and rectum: retrospective cohort study

BJS Open, Volume 4, Issue 6, Page 1200-1207, December 2020., 2020
Few studies have evaluated the growth pattern of colorectal cancer. Forty‐three patients who underwent CT twice more than 5 weeks apart were included over a 2‐year interval. The median doubling time was 211 days, with a concerning suggestion of tumour progression.

Análisis clínico-tomográfico en obstrucción de intestino delgado por adherencias según el sitio de obstrucción en la tomografía

Revista Colombiana de Cirugía, 2021
Introducción. Las adherencias postoperatorias son la causa más frecuente de obstrucción de intestino delgado. La clínica sugiere el diagnóstico, pero de manera poco precisa la causa y el sitio de la obstrucción. La tomografía computarizada contrastada es

Time to definitive care within major trauma networks in England

BJS Open, Volume 4, Issue 5, Page 963-969, October 2020., 2020
This article describes timelines from emergency service activation to urgent surgery for seriously injured patients in England following implementation of regional trauma networks in 2012. Analysis showed that seriously injured patients undergoing secondary transfer to definitive care had delayed imaging, delayed surgery and increased mortality.

Intermittent pneumatic compression versus additional prophylaxis with enoxaparin for prevention of venous thromboembolism after laparoscopic surgery for gastric and colorectal malignancies: multicentre randomized clinical trial

BJS Open, Volume 4, Issue 5, Page 804-810, October 2020., 2020
This RCT compared intermittent pneumatic compression (IPC) alone with IPC plus enoxaparin for 1 week after surgery in the prevention of venous thromboembolism (VTE) in patients undergoing laparoscopic surgery for gastric or colorectal malignancy. Although VTE occurred in 4·8 per cent of the ICP‐alone group and 3·3 per cent of the ICP with enoxaparin ...

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.
