[Physical Strain after Abdominal Surgery - Results of a Patient Survey]

Incision hernias are common complications after abdominal surgery and affect the recommendations on postoperative physical strain, as it is thought that excessively early strain causes incisional hernias. However, there is no evidence to justify this. This study evaluates the effect of postoperative strain on the risk of incisional hernia.

Patients with a laparoscopy (LS) or laparotomy (LT) were asked to complete a questionnaire on postoperative strain, complaints and quality of life. Patients with hernia surgery, or open abdomen therapy for complicated courses (Clavien-Dindo > III) were excluded.

393 patients completed the questionnaire (43.6%). 274 were LS and 128 LT. The incidence of incisional hernias was 5.2% (LS) and 18.0% (LT, p = 0.001). Incisional hernia patients were younger and more commonly males. 30.5% of incisional hernia patients did not return to normal physical strain postoperatively. Abdominal binders did not affect the hernia rate. The incisional hernia patients showed decreased quality of life scores in both mental and physical domains.

Early postoperative physical strain was not a risk factor for incisional hernia development in this study. However, prospective studies are needed to create necessary evidence to recommend earlier postoperative return to normal physical strain.
