Details and patient eligibility

About

The aim of this study is to describe the development of symptomatic and asymptomatic incisional hernias after emergency midline laparotomy over time in high-risk patients evaluated by consecutive MRI-scans.

Full description

All patients operated with an emergency midline laparotomy in our clinic are potential participants and will be screened for participation. Potential participants will be briefly informed about the project by the hospital staff. If the patients are interested, they will be thoroughly informed about the study and asked to participate by one of the trial investigators before discharge.

Data will be obtained from the participants hospital files and by patient survey/interview. All data will be entered into a database using RedCap by trial investigators or their delegates.

Enrolled patients will be followed for two years. The trial involves four consecutive MRI-scans one month, three months, six months and two years after surgery. Change in quality of life, physical functioning and pain-score are also obtained by patient survey/interview at each visit. A concluding physical examination and abdominal wall ultrasound examination will be performed two years after the surgery.

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Unscheduled midline laparotomy in an emergency or subacute setting, involving perforated bowel, bowel obstruction, bowel ischemia (due to mesenteric vascular disease or incarceration), inflammatory diseases (e.g. diverticulitis, appendicitis, ulcerative colitis, cholecystitis and Crohn's disease), abscesses, non-traumatic intraabdominal bleeding or any emergency re-operation to elective surgery
• Age of 18 years or above
• BMI above 27
• At least one risk factor for incisional hernia i.e. earlier midline laparotomy, BMI > 30, abdominal aortic aneurysm or prior surgery for abdominal aortic aneurysm, active smoking, liver cirrhosis, re-laparotomy, age > 75, history of primary ventral hernia (treated or untreated before index surgery), large laparotomy involving more than 2/3 of the abdominal wall as measured from the xiphoid process to the pubic bone

Exclusion criteria

• Malign, incurable disease
• Other reasons for short life expectancy <2 year as evaluated by the investigator
• Midline-incisions <15 cm
• Mesh augmentation of abdominal wall closure at index surgery or earlier mesh augmentation of the abdominal wall
• Severe claustrophobia or any other mental habitus, making it impossible to perform MRI-scan without sedation
• Metallic magnetic implants that serves as a contraindication for MRI-scan (including pacemakers, large tattoos, insulin pumps, etc.)
• Metallic prosthetic non-magnetic implants that are suspected to create severe artefacts on the MRI-scan of the abdominal wall
