The free Gastrointestinal Surgical Emergencies textbook is a resource for surgeons at all career stages looking for knowledge and information from world-renowned leaders on the signs and symptoms of surgical diseases commonly encountered in emergency gastrointestinal surgery, identification of treatment options, and employment of best practices in emergency situations. The textbook is a result of the popular Gastrointestinal Surgical Emergencies course first held by the ACS’ Italy Chapter and later Argentina Chapter through the International Chapter Opportunity Program funded through the generosity of Pon Satitpunwaycha, MD, FACS.
