BACKGROUND: Abdominal wall surgery has changed dramatically in recent years. The current management of lumbar hernias should reflect the development of modern imaging techniques and new forms of noninvasive treatment. OBJECTIVE: To review and update knowledge on lumbar hernias. DATA SOURCES: Literature review using MEDLINE with the key words "lumbar hernia" for the years 1950 through 2004. For an analysis prior to this date (1750-1950), we used cases reported by Thorek. Our own study of 28 patients was also included. STUDY SELECTION: All articles reporting clinical cases on lumbar hernia. DATA EXTRACTION: Two reviewers analyzed the epidemiological, clinical, and treatment data of the articles. DATA SYNTHESIS: One hundred thirty-five clinical case articles and 8 studies with more than 5 patients, together with our personal experience of 28 cases, were analyzed. Nine percent of acquired lumbar hernia cases presented for emergency surgery, which means that a clinical diagnosis was completed with computed tomography in more than 90% of the cases. None of the published classifications has a therapeutic orientation. We present an original classification based on 6 categories and 4 types. In our study, there was a predominance of incisional hernias (79%), with no difference with regard to sex or location but with a predominance in the upper space (47%). Laparoscopic treatment accounts for 9% of the publications' cases and there is only 1 prospective comparative study. CONCLUSIONS: The use of a complete classification and tomography must be standard practice in the preoperative protocol of patients with lumbar hernia. The laparoscopic approach seems to be the best option for treating small or moderate defects; open surgery can be reserved for large defects and to salvage failures with the laparoscopic approach.
The Prolene Hernia System (PHS) is already widely in use in the United Kingdom for inguinal hernias. We describe the novel technique of using the three-in-one design of the PHS (Ethicon Endo-Surgery, Bracknell, UK) for repairing incisional, epigastric and umbilical herniae. This is a three-dimensional device and consists of an onlay patch, a tubular connector and an underlay patch. We recommend a four 'corner' suturing of the underlay patch under vision (and then) through the full thickness of abdominal wall layers to ensure a flat underlay mesh. These four sutures flatten out the underlay patch and can be tied or removed with equal effect. The sutures are placed at 3, 6, 9 and 12 o'clock, which simplifies the procedure and ensures that the underlay lays correctly and is corrugation-free and tension-free, thereby providing a two-layer repair for those herniae with a high rate of recurrence.
The anatomic characteristics of the anterior abdominal wall allow the harvesting of various types of flaps, some of them with considerable volume. These flaps are used mainly for reconstruction of the female breast, thoracic wall, and perineal or ilioinguinal region. Even though general donor site morbidity is low, hernias and "bulging" can occur due to the harvest of muscle and fascia, which leads to a weakening of the abdominal wall. Hernias and bulging appear mostly after harvest of classic flap types, which include removal of the rectus abdominis muscle. Further refinements of these flaps, i.e. microvascular flaps, in particular perforator flaps, lead to a marked reduction in donor site morbidity. In the following overview, the problem of abdominal wall weakening as a result of flap harvest is discussed and possible therapeutic options are elucidated.
