Enhanced postoperative recovery programmes (ERAS) were developed about 20 years ago based on improved understanding of the pathophysiology of postoperative recovery within an integrated multidisciplinary approach. The results across surgical procedures have been extremely positive with a reduction in hospitalisation and medical complications, without increased re-admission rates. However, several challenges lie ahead including improved implementation of existing scientific evidence, increased focus on post-discharge recovery problems and a need for improved design of future ERAS studies. ⋯ These efforts should focus on: the inflammatory and neurohumoral surgical stress responses; fluid management; pain management; blood management; mechanisms of orthostatic intolerance; postoperative cognitive dysfunction; risk factors for thrombo-embolic complications; and mechanisms and prevention of postoperative ileus. Finally, more focus should be made on the different barriers to post-discharge functional recovery and the choice of (pre- and postoperative) rehabilitation. These efforts should be made on a procedure-specific as well as on a patient-specific basis.

Standardised peri-operative care pathways for patients undergoing emergency laparotomy or laparoscopy for non-traumatic pathologies have been shown to be inadequate and associated with high morbidity and mortality. Recent research has highlighted this problem and showed that simple pathways with 'rescue' interventions have been associated with reduced mortality when implemented successfully. These rescue pathways have focused on early diagnosis and surgery, specialist surgeon and anaesthetist involvement, goal-directed therapy and intensive or intermediary postoperative care for high-risk patients. ⋯ In order to move beyond rescue pathways and to establish enhanced recovery for emergency laparotomy, it is essential that research on both the peri-operative pathophysiology of the different main patient groups - intestinal obstruction and perforation - and the potentially differentiated impact of interventions is carried out. Procedure- and pathology-specific knowledge is lacking on key elements of peri-operative care, such as: multimodal analgesia; haemodynamic optimisation and fluid management; attenuation of surgical stress; nutritional optimisation; facilitation of mobilisation; and the optimal use and organisation of specialised wards and improved interdisciplinary collaboration. As such, the future challenges in improving peri-operative patient care in emergency laparotomy are moving from simple rescue pathways to establish research that can form a basis for morbidity- and procedure-specific enhanced recovery protocols as seen in elective surgery.
