Impact of Core Muscle Training on Incisional Hernia and Pain After Abdominal Surgery

Обзор

The current practice to avoid incisional hernia, one of the most frequent complications following abdominal surgery, is to minimize core muscle activity in the postoperative phase. However, there is no evidence to support the association of core muscle activity and increased incidence of incisional hernia. On the contrary, it is likely that reduced physical activity could lead to physical deconditioning, chronic postsurgical pain (CPSP), and sarcopenia. The investigators will conduct a prospective multicentric randomized clinical trial to compare standard of care to core muscle exercises targeting the abdominal muscles immediately postsurgery. The principle hypothesis is that neither specific exercises of core muscles before and after surgery nor physical restriction alter the incidence of incisional hernias. Secondly the impact of postoperative rehabilitation on CPSP and sarcopenia will be assessed.

Подробное описание

The current practice to avoid incisional hernia, one of the most frequent complications following abdominal surgery, is to minimize core muscle activity in the postoperative phase. Therefore the patients are instructed not to bear or lift weights and to limit physical activities in the first 8-12 weeks after surgery. However, there is no evidence to support the association of core muscle activity and increased incidence of incisional hernia. On the contrary, it is likely that reduced physical activity and deconditioning of the core muscles is associated with muscle catabolism, which may lead to physical deconditioning, chronic postsurgical pain (CPSP), and sarcopenia. CPSP is primarily a major burden in terms of reduced quality of life and resource utilization whereas sarcopenia in addition is increasingly recognized as an important independent risk factor for numerous adverse clinical outcomes and mortality.

The investigators will conduct a prospective multicentric randomized clinical trial to compare standard of care to core muscle exercises targeting the abdominal muscles immediately postsurgery. The principle hypothesis is that neither specific exercises of core muscles before and after surgery nor physical restriction alter the incidence of incisional hernias. Secondly the impact of postoperative rehabilitation on CPSP and sarcopenia will be assessed. The patients will be divided into two study arms, one receiving standard of care and the other receiving the intervention. The intervention consists of four specific core muscle exercises to perform daily during the first two months after surgery. Follow-up will be at two, twelve and twenty-four months with clinical examination and ultrasound to detect incisional hernias, assessment chronic postsurgical pain and its treatment and evaluation of muscle mass on CT scans.
