[Relaparotomy, retrospective analysis and intensive care aspects]

Area of Science:

• Surgical outcomes research
• Clinical epidemiology

Context:

• Analysis of 2441 laparotomies and 92 relaparotomies performed between 1977-1979 at the Surgical University Clinic Mainz.
• Identified high mortality rates associated with specific patient demographics and pre-existing conditions.

Purpose:

• To identify risk factors associated with high mortality rates in patients undergoing relaparotomy.
• To explore factors correlating with lower mortality in specific surgical scenarios.

Summary:

• High mortality in relaparotomy patients (40% fatal) was associated with female sex, advanced age in males, malignancy (pancreatic, colon, rectal cancer), gastrointestinal bleeding, multiple comorbidities (especially angiocardiopathy), and post-radiotherapy status.
• Conversely, lower mortality was observed in emergency primary laparotomies, early (within 2 days) or late (after weeks) postoperative complications, and multiple relaparotomies with intervals of at least two weeks.
• Relaparotomy is indicated for severe complications like renal and respiratory insufficiency if the intra-abdominal issue is treatable, as intensive care alone is insufficient, but mechanical ventilation and dialysis can improve outcomes. A contraindication for relaparotomy exists with the "lethal trias" of renal and respiratory insufficiency and an untreatable surgical problem.

Impact:

• Provides critical insights into predicting and potentially mitigating mortality risks in complex surgical cases requiring relaparotomy.
• Informs clinical decision-making regarding the indication and timing of relaparotomy, especially in patients with multiple organ system failures.
