This book constitutes the refereed proceedings of the first MICCAI Workshop, ISGIE 2022, Imaging Systems for GI Endoscopy, and the Fourth MICCAI Workshop, GRAIL 2022, GRaphs in biomedicAL Image and analysis, held in conjunction with MICCAI 2022, Singapore, September 18, 2022. ISGIE 2022 accepted 6 papers from the 8 submissions received.This workshop focuses on novel scientific contributions to vision systems, imaging algorithms as well as the autonomous system for endorobot for GI endoscopy. This includes lesion and lumen detection, as well as 3D reconstruction of the GI tract and hand-eye coordination. GRAIL 2022 accepted 6 papers from the 10 submissions received. The workshop aims to bring together scientists that use and develop graph-based models for the analysis of biomedical images and to encourage the exploration of graph-based models for difficult clinical problems within a variety of biomedical imaging contexts.

This book is novel in that it is a single volume offering useful practical tips in the performance of the broad range of procedures used by gastroenterologists, interventional radiologists and surgeons in the current management of complicated abdominal emergencies and traumatic injuries. Emphasis is placed on practical tips which could be life-saving.The contributors are experienced staff members from the National University Hospital, Singapore. Through a step-by-step narrative and an abundance of medical illustrations, the contributors impart to the reader how best to perform and overcome difficulties encountered in the management of complicated abdominal emergencies. Learning is enhanced by video clips of procedures recorded live, in the DVD-ROM that accompanies the book.
