Treatment of the abdominal wall defects in an ambulatory surgical setting: our experience.

Introduction: The creation of Outpatient Surgery (OPS) units has allowed to reduce the costs and the waiting lists in an efficient fashion. We describe our series of patients operated on for abdominal wall defects, a pathology suitable for ambulatory surgery. Patients and methods: Between May 1994 and March 1998, 206 inguinal hernias, 23 femoral hernias, 47 umbilical-epigastric hernias and nine incisional hernias were operated on in an ambulatory surgical setting. The patients were selected following the selection criteria previously established (related to the patient, the environment and the surgical procedure). The average age was 45 years, and the distribution by sex, 210 men and 75 women. Spinal anesthesia was preferently performed. The surgical techniques employed were Lichtenstein's hernioplasty and Shouldice and Bassini procedures for inguinal hernias; Lichtenstein's plug technique for femoral hernias and simple closure or preperitoneal mesh for the middle line defects. Results: 44 patients needed readmitttance to hospital (failure of OPS), the most important causes being excessive pain, urinary retention and nausea/vomiting. There was no severe morbidity nor mortality. Conclusion: Surgery for abdominal wall defects constitutes a group of procedures suitable for efficient and low risk OPS programs.
