ABSTRACT Mesh hernioplasty is the preferred surgical procedure for large abdominal wall hernias. Infection remains one of the most challenging complications of this operation. Salvaging infected prosthetic material after ventral hernia repair is rarely successful. Most cases require mesh excision and complex abdominal wall reconstruction, with variable success rates. In this article, we report 3 cases of mesh salvage after laparoscopic ventral herniorrhapy with a novel use of percutaneous drainage and antibiotic irrigation.
Three patients developed infected seromas after laparoscopic ventral hernia repair. The fascial defect of the first patient was repaired with a commercially available 20 x 18 cm polytetrafluoroethylene (PTFE) mesh. A complex fluid collection developed the following month in the anterior abdominal wall overlying the patient's mesh. The cultures grew Staphylococcus aureus. The second patient had a 30 x 20 cm PTFE mesh placed, which developed a fluid collection with Enterococcus faecalis and Escherichia coli. The third case underwent repair, using a another commercially available 22 x 28 cm PTFE mesh. A fluid collection measuring 20 x 10 cm in the anterior abdominal wall developed, growing Staphylococcus lugdunensis. In all 3 cases, a percutaneous drain was placed within the fluid collection and long-term intravenous (i.v.) access was obtained. I.v. antibiotics were initiated. In addition, gentamicin (80 mg) with 20 mL of saline was infused through the drain 3 times a day. All patients have remained free of clinical signs of infection following the completion of therapy.
Infected mesh after laparoscopic ventral herniorrhapy without systemic sepsis may be amenable to nonoperative treatment. A conservative approach that includes percutaneous drainage followed by antibiotic irrigation is a potential alternative to prosthetic removal in carefully selected patients. Further evaluation of this technique is warranted to define the most appropriate management strategies for these patients.

    ABSTRACT: Ventral hernias (VHs) are abnormal openings in the anterior abdominal wall that are common side effects of surgical intervention. Repair of VHs is the most commonly performed procedure by general surgeons worldwide, but VH repair outcomes are not particularly encouraging (with recurrence rates up to 43%). A variety of open and laparoscopic techniques are available for hernia repair, and the specific technique used is ultimately driven by surgeon preference and experience. Despite routine acquisition of computed tomography (CT) for VH patients, little quantitative information is available on which to guide selection of a particular approach and/or optimize patient-specific treatment. From anecdotal interviews, the success of VH repair procedures correlates with hernia size, location, and involvement of secondary structures. Herein, we propose an image labeling protocol to segment the anterior abdominal area to provide a geometric basis with which to derive biomarkers and evaluate treatment efficacy. Based on routine clinical CT data, we are able to identify inner and outer surfaces of the abdominal walls and the herniated volume. This is the first formal presentation of a protocol to quantify these structures on abdominal CT. The intra- and inter rater reproducibilities of this protocol are evaluated on 4 patients with suspected VH (3 patients were ultimately diagnosed with VH while 1 was not). Mean surfaces distances of less than 2mm were achieved for all structures.

    ABSTRACT: A dreaded complication of laparoscopic hernia repair is infection of the mesh. Traditionally mesh infection is managed by surgical removal of the mesh, an extensive procedure resulting in high re-herniation rates. A technique to treat such infections whilst salvaging the mesh is sorely needed. We describe a case in which a laparoscopic mesh infection was treated solely with drainage, parenteral antibiotics and antibiotic irrigation of the mesh. A 65 year old gentleman presented 11 months post laparoscopic repair of an inguinal hernia with malaise and an uncomfortable groin swelling. Computed tomography scanning revealed a collection surrounding the mesh which was drained and cultured to show heavy growth of Staphylococcus aureus. A pigtail drain on continuous drainage was inserted and kept in situ for 7 weeks. The patient received one week of intravenous flucloxacillin and two gentamycin irrigations through the drain as an inpatient. He then received 6 weeks of oral flucloxacillin and bi-weekly saline flushes through the drain in the community. By 12 weeks an ultrasound scan showed resolution of the collection. At 7 months he remains clinically free from recurrence. Here we report a novel conservative method used to treat a hernia mesh infection, preserve the mesh and avoid major surgery. Other reports exist suggesting variations in conservative methods to treat mesh infections, however ours is by far the most conservative. Clearly, further research is required to identify which method is most effective and in which patients it is likely to be successful.

    ABSTRACT: Immersive virtual environments use a stereoscopic head-mounted display and data glove to create high fidelity virtual experiences in which users can interact with three-dimensional models and perceive relationships at their true scale. This stands in stark contrast to traditional PACS-based infrastructure in which images are viewed as stacks of two-dimensional slices, or, at best, disembodied renderings. Although there has substantial innovation in immersive virtual environments for entertainment and consumer media, these technologies have not been widely applied in clinical applications. Here, we consider potential applications of immersive virtual environments for ventral hernia patients with abdominal computed tomography imaging data. Nearly a half million ventral hernias occur in the United States each year, and hernia repair is the most commonly performed general surgery operation worldwide. A significant problem in these conditions is communicating the urgency, degree of severity, and impact of a hernia (and potential repair) on patient quality of life. Hernias are defined by ruptures in the abdominal wall (i.e., the absence of healthy tissues) rather than a growth (e.g., cancer); therefore, understanding a hernia necessitates understanding the entire abdomen. Our environment allows surgeons and patients to view body scans at scale and interact with these virtual models using a data glove. This visualization and interaction allows users to perceive the relationship between physical structures and medical imaging data. The system provides close integration of PACS-based CT data with immersive virtual environments and creates opportunities to study and optimize interfaces for patient communication, operative planning, and medical education.
