Patient public perspectives on digital colorectal cancer surgery (DALLAS).

Introduction: The importance of patient perspectives is increasingly appreciated in clinical practice and academia with formal engagement processes developing worldwide. Digital surgery encompasses intraoperative patient data (including surgical video) analysis and so requires public-patient involvement (PPI).

Methods: Engagement events were conducted based on NIHR and GRIPP2 LF guidelines.

Clinical validation of 3D virtual modelling for laparoscopic complete mesocolic excision with central vascular ligation for proximal colon cancer.

Introduction: Laparoscopic Complete Mesocolic Excision (CME) with Central Vascular Ligation (CVL) in colon cancer surgery has not been broadly adopted in part because of safety concerns. Pre-operative 3-D virtual modelling (3DVM) may help but needs validation.

Methods: 3DVM were routinely constructed from CT mesenteric angiograms (CTMA) using a commercial service (Visible Patient, Strasbourg, France) for consecutive patients during our CMECVL learning curve over three years.

Double check: diagnosis and management of adult Hirschsprung disease.

Hirschsprung disease (HD) is a gut motility disorder usually diagnosed acutely in infancy, although variants of HD may present later in life with indolent symptoms. This report highlights the rarity of diagnosing HD and hypoganglionosis in adulthood and the nuances that need consideration for their surgical management. We present a report of a 49-year-old man presenting with chronic constipation.
