Purpose: The most recent international guideline on inguinal hernia management recommends a short convalescence after repair. However, surgeons’ recommendations may vary. The objective of this study was to give an overview of the current convalescence recommendations in the literature subdivided on the Lichtenstein and laparoscopic inguinal hernia repairs. Methods: In this systematic review, three databases were searched in August 2021 to identify studies on inguinal hernia repairs with a statement about postoperative convalescence recommendations. The outcome was convalescence recommendations subdivided on daily activities, light work, heavy lifting, and sport. Results: In total, 91 studies fulfilled the eligibility criteria, and 50 and 58 studies reported about convalescence recommendations after Lichtenstein and laparoscopic repairs, respectively. Patients were instructed with a wide range of convalescence recommendations. A total of 34 Lichtenstein studies and 35 laparoscopic studies recommended resumption of daily activities as soon as possible. Following Lichtenstein repairs, the patients were instructed to resume light work after median 0 days (interquartile range (IQR) 0–0), heavy lifting after 42 days (IQR 14–42), and sport after 7 days (IQR 0–29). Following laparoscopic procedures, the patients were instructed to resume light work after median 0 days (IQR 0–0), heavy lifting after 14 days (IQR 10–28), and sport after 12 days (IQR 7–23). Conclusion: This study revealed a broad spectrum of convalescence recommendations depending on activity level following inguinal hernia repair, which likely reflects a lack of high-quality evidence within this field.
