Repair of giant incisional abdominal wall hernias using open intraperitoneal mesh

Background Very large and complex incisional hernias, especially those involving loss of abdominal wall, present a particular challenge to the surgeon. Aims The open intraperitoneal technique was used prospectively for the repair of incisional hernias in a selected group of patients with large defects, often those with major loss of abdominal wall, overweight patients, and previous failures of incisional repair. Materials and methods Between 1 January 1999 and 31 December 2005, out of 275 patients operated on for incisional hernia repair, 61 of them, most of whom were obese with multiorificial recurrent or giant hernias and contraindicated for laparoscopy, were treated using an open intraperitoneal mesh technique. There were 50 females and 11 males, with a mean age of 61. The median ASA score of the group was 2.3, with a mean BMI of 34 kg/m² and a mean hernia surface of 182 cm². Sixty-four percent of the patients had undergone one or more previous incisional hernia repairs. Results Mean operating time was 130 min, with an average hospital stay of 13 days. None of the patients died. Postoperative complications occurred in 21% of the patients; most of which were minor, but two cases (3.3%) developed deep abscesses requiring surgery and removal of the mesh. A recurrence rate of 5% was found after a mean follow-up of 35 months (8–88). Conclusion Open intraperitoneal mesh repair appears to be a good option for the treatment of complex incisional hernia (at least 10 cm in diameter or multiorificial) in obese patients contraindicated for laparoscopy.     

Abdominal wall compliance after Marlex® mesh implantation for incisional hernia repair

Summary In view of the poor results of suturing techniques, incisional hernias are often best repaired with biomaterials. Their use brings the recurrence rate to below 10%, but patients sometimes complain of discomfort and restricted abdominal mobility. We report our experience with 41 patients after implantation of a Marlex®-mesh in a preperitoneal, retromuscular position (mean follow-up period 16.7 months). The effect of implanted meshes on abdominal wall mobility was measured noninvasively with the aid of three dimensional stereography and compared with a non-operated healthy control group (n = 21). The commonest early postoperative complication was seroma in 32% of cases, usually relieved by aspiration. Infection and hematoma were less frequent at 4.9% and 12.2% respectively. Three patients developed a recurrent hernia. During follow-up 7.3% experienced pain during heavy activities, 29.3% during daily activities and 4.9% at rest. Three dimensional stereography showed a highly significant (p < 0.001) decrease in abdominal wall mobility following mesh implantation, compared to a non-operated control group. Improved composition of the mesh material involving a smaller proportion of polypropylene and greater elasticity, should be considered for the future, in order to reduce patient discomfort.The study was supported by BIOMAT (Interdisciplinary Centre of Clinical Investigation, RWTH Aachen).     

Operative Therapie der Narbenhernie

Secondary ventral hernia or incisional hernia occurs in at least 20?% of cases after laparotomy and most patients are symptomatic. The pathogenesis of incisional hernia is believed to be based on a defect in collagen synthesis indicating the necessity of covering the whole original incision with a non-resorbable, macroporous mesh. These meshes can be used on top of the fascia (onlay), in a retromuscular fashion (sublay) or intraperitoneally (IPOM). The IPOM technique is the preferred procedure during laparoscopic repair of ventral hernias. The clear advantage of the laparoscopic approach is the dramatically reduced rate of wound complications, especially infections. Major defects of the abdominal wall require plastic reconstruction with the component separation technique in both anterior and posterior approaches. The component separation technique must be combined with retromuscular mesh augmentation enabling a recurrence rate of less than 10 % and an acceptable morbidity to be achieved.     

Incisional hernia treatment with progressive pneumoperitoneum and retromuscular prosthetic hernioplasty

BACKGROUND AND AIM: Major incisional hernias of the abdominal wall often pose a serious surgical problem. The choice between simple suture repair and mesh repair remains uncertain. METHODS: Seventy-seven patients underwent surgery to repair large abdominal incisional hernias, i.e., with parietal defects of 10 cm or more, by retromuscular prosthetic hernioplasty between 1996 and 1999. All patients were treated preoperatively by progressive pneumoperitoneum and were followed up for 2-5 years (mean 38.3 months). RESULTS: Almost all patients tolerated the pneumoperitoneum; no postoperative death occurred. Six patients developed a subcutaneous infection but none of them required removal of the mesh. Two patients (2.6%) had recurrent incisional hernia. CONCLUSIONS: This study shows that pneumoperitoneum is useful in preparing patients for incisional hernioplasty. Retromuscular mesh repair represents an appropriate surgical procedure, particularly in view of its low rate of recurrence.     

Incisional intercostal hernia after a nephrectomy

The aim of the present case report is to present the diagnostic and therapeutic challenge of intercostal incisional hernia. We report on a female patient with leftsided intercostal incisional hernia between the eleventh and twelfth rib due to preceding lumbar incision for tumor nephrectomy. Because of its infrequence, diagnosis was established late although simple clinical examination and ultrasound investigation displayed the hernia. At laparotomy, a 5×5 cm² fascial defect with a colonic sliding hernia was found. Hernia repair using permanent mesh reinforcement in the retromuscular position is described. Abdominal incisional hernia in the intercostal region is rare and therefore easily overlooked. As with other incisional hernias, the hernia repair using mesh implantation in the retromuscular region is technically feasible and represents the treatment of choice.     

Incisional hernia repair after orthotopic liver transplantation: a technique employing an inlay/onlay polypropylene mesh

Background: The literature provides no data on the incidence and operative management of incisional hernias developing after orthotopic liver transplantation. The use of high-dose immunosuppressive agents results in an appreciable delay in wound healing. There is thus a need for a procedure for the reconstruction of the abdominal wall for patients on immunosuppression. The aim of this retrospective study was to establish the incidence of incisional hernias and an analysis of the results after implantation of a polypropylene mesh in inlay–onlay technique after liver transplantation is given.Methods: The basis for the present retrospective investigations was a total of 207 liver transplantations carried out in 192 patients (15 re-transplantations). After performing tensiometry, a polypropylene mesh (Marlex) was implanted to close the hernias using the inlay/onlay technique or a direct closure of the fascia was done. All treated hernias were followed up for a median of 18 months.Results: Among 184 patients, 17 developed incisional hernias after primary direct closure of the abdominal wall, giving an incidence of 9%. In an additional 8 patients an incisional hernia was seen where an absorbable mesh was used to close the abdominal wall after liver transplantation. In addition, there were 25 incisional hernias after 207 liver transplantations (12%). One of 15 (7%) of the surgically repaired hernias with implantation of a polypropylene mesh (Marlex) developed a recurrence. All the 3 patients after direct apposition of the fascia without using a polypropylene mesh suffered a recurrence (3 of 3; 100%). Significant risk factors for developing an incisional hernia were the amount of ascites and the stay in the ICU after transplantation. Neither severe deep nor superficial wound infection nor bowel fistulas were observed after implantation of a inlay/onlay mesh.Conclusion: In patients after liver transplantation, the implantation of a polypropylene mesh proved to be an efficient and safe method of treating incisional hernias. Implantation of a mesh was not associated with an increased infection rate, despite the use of immunosuppression. In view of the high recurrence rate associated with primary closure, mesh implantation should be given preference.     

Polyvinylidene fluoride: a suitable mesh material for laparoscopic incisional and parastomal hernia repair!

Background

Today, the laparoscopic approach is a standard procedure for the repair of incisional hernias. However, the direct contact of visceral organs with mesh material is a major issue.

Patients and methods

This prospective observational study presents the data of 344 patients treated for incisional and parastomal hernias with a new mesh made of polyvinylidene fluoride (PVDF; Dynamesh IPOM^®) between May 2004 and January 2008 with a minimum follow-up of 6 months. The median follow-up of 297 patients after incisional hernias totaled 24 months and 20 months for 47 patients with parastomal hernias. Incisional hernias were repaired using an IPOM technique. For parastomal hernias, a recently described sandwich technique was used with two meshes implanted in an intraperitoneal onlay position.

Results

The recurrence rate for incisional hernias was 2/297 = 0.6% and 1/47 = 2% for parastomal hernias. Three patients developed a secondary infection after surgical revision or puncture of a seroma. One patient had a bowel fistula through the mesh, with an abscess in the hernia sac. In all cases, the infection healed and the mesh could be preserved. No long-term mesh-related complications have been observed.

Conclusion

The laparoscopic repair of incisional and parastomal hernias with meshes made of PVDF (Dynamesh IPOM^®) revealed low recurrence and, overall, low complication rates. Especially in cases of infection, the material proved to be resistant without clinical signs of persistent bacterial contamination. Mesh-related complications did not occur during the follow-up.     

The peritoneal flap hernioplasty for repair of large ventral and incisional hernias

Background

Mesh repair of large ventral or incisional hernias is problematic when primary fascial closure cannot be achieved, as this leaves mesh exposed, bridging the gap. We describe a modified retromuscular sublay repair which overcomes this problem and report a retrospective review of cases to assess outcome.

Methods

Mesh is positioned between transposed flaps of preserved hernial sac and rectus sheath. Patients undergoing this repair by one author (BT) from 1 January 2004 to 31 December 2010 were identified, and clinical outcome was assessed by a combination of case-note review, outpatient consultation and telephone interview.

Results

Twenty-one ventral and incisional hernias were treated by this method. Eighteen were incisional (13 midline, three transverse and two oblique incisions), and three were primary paraumbilical hernias. Defect sizes ranged from 25 to 500 cm² and mesh sizes from 300 to 900 cm². Patients were reviewed at 6 weeks, 6 months and at a median of 37 months post-operatively. Three cases of superficial skin edge necrosis, two superficial wound infections and two sizeable seromas developed, but all had resolved within 6 months. One patient developed abdominal wall necrosis requiring mesh removal and eventual abdominal wall reconstruction without mesh, resulting in late recurrence. All other cases achieved excellent long-term outcomes with a high degree of patient satisfaction.

Conclusion

This is a useful method for repairing large ventral and incisional hernias when primary fascial closure is not achievable, combining a sublay mesh repair with autologous tissue transposition across the fascial gap.     

Implantation of Prophylactic Nonabsorbable Intraperitoneal Mesh in Patients With Peritonitis Is Safe and Feasible

Background

Patients with peritonitis undergoing emergency laparotomy are at increased risk for postoperative open abdomen and incisional hernia. This study aimed to evaluate the outcome of prophylactic intraperitoneal mesh implantation compared with conventional abdominal wall closure in patients with peritonitis undergoing emergency laparotomy.

Method

A matched case-control study was performed. To analyze a high-risk population for incisional hernia formation, only patients with at least two of the following risk factors were included: male sex, body mass index (BMI) >25 kg/m², malignant tumor, or previous abdominal incision. In 63 patients with peritonitis, a prophylactic nonabsorbable mesh was implanted intraperitoneally between 2005 and 2010. These patients were compared with 70 patients with the same risk factors and peritonitis undergoing emergency laparotomy over a 1-year period (2008) who underwent conventional abdominal closure without mesh implantation.

Results

Demographic parameters, including sex, age, BMI, grade of intraabdominal infection, and operating time were comparable in the two groups. Incidence of surgical site infections (SSIs) was not different between groups (61.9 vs. 60.3 %; p = 0.603). Enterocutaneous fistula occurred in three patients in the mesh group (4.8 %) and in two patients in the control group (2.9 %; p = 0.667). The incidence of incisional hernia was significantly lower in the mesh group (2/63 patients) than in the control group (20/70 patients) (3.2 vs. 28.6 %; p < 0.001).

Conclusions

Prophylactic intraperitoneal mesh can be safely implanted in patients with peritonitis. It significantly reduces the incidence of incisional hernia. The incidences of SSI and enterocutaneous fistula formation were similar to those seen with conventional abdominal closure.     

Surgical treatment of large incisional hernias by an intraperitoneal Dacron mesh and an aponeurotic graft

BACKGROUND: The therapeutic problems of giant incisional hernias of the abdominal wall are difficult to resolve. The technique of repair must make up for the loss of abdominal wall substance and reestablish the interplay of the abdominal musculature. The use of prosthetic materials complies with these two imperatives. The aim of this prospective study was to evaluate the results of surgical treatment of postoperative incisional hernias by intraperitoneal insertion of Dacron (DuPont) mesh and an aponeurotic graft. STUDY DESIGN: We prospectively studied 350 consecutive patients who were operated on for giant postoperative incisional hernia. RESULTS: Postoperative mortality was 0.6%. Seven patients (2%) developed subcutaneous infections that did not affect the prostheses. Another seven patients (2%) developed deep-seated infections that necessitated removal of the mesh in five cases. Eleven patients (3.1%) had recurrence of incisional hernia. CONCLUSIONS: This prospective study shows that the intraperitoneal positioning of Dacron mesh and an aponeurotic graft can efficiently treat giant abdominal wall hernias.     

Incisional hernia of the abdominal wall. Pathophysiology, etiology and prosthetic repair techniques]

Postoperative incisional hernia is defined by 3 essential criteria, based on a perfect clinico-pathological knowledge of the abdominal wall: the site, dimensions, and defect. Two main elements predispose to incisional hernia: infection and mechanical factors. Local and systemic complications, accentuated in large incisional hernias, are respectively defined by two concepts: "incisional hernia lesion" and "incisional hernia disease". Precise assessment of these elements can guide the surgeon's operative strategy. Incisional hernias remain a relatively frequent complication of abdominal surgery. All of these patients generally require surgical repair of the abdominal wall. A French national survey showed that most surgeons now use prosthetic materials in 60% of primary repairs, and in 85% of recurrent cases. After reviewing the biomechanical characteristics and the in vivo behaviour of commercially available prostheses, the technical principles of prosthetic abdominal wall surgery will be considered together with the various implantation sites: retromuscular, intraperitoneal and premuscular. Based on their personal experience of 110 cases of large incisional hernias, treated between 1989 and 1998, the authors recommend the intraperitoneal position using expanded polytetrafluoroethylene, a reliable material which is well tolerated in contact with the viscera.

A novel technique of lumbar hernia repair using bone anchor fixation

Lumbar hernias are difficult to repair due to their proximity to bone and inadequate surrounding tissue to buttress the repair. We analyzed the outcome of patients undergoing a novel retromuscular lumbar hernia repair technique. The repair was performed in ten patients using a polypropylene or polytetrafluoroethylene mesh placed in an extraperitoneal, retromuscular position with at least 5 cm overlap of the hernia defect. The mesh was fixed with circumferential, transfascial, permanent sutures and inferiorly fixed to the iliac crest by suture bone anchors. Five hernias were recurrent, and five were incarcerated; seven were incisional hernias, and three were posttraumatic. Back and abdominal pain was the most common presenting symptom. Mean hernia size was 227 cm² (60–504) with a mesh size of 620 cm² (224–936). Mean operative time was 181 min (120-269), with a mean blood loss of 128 ml (50–200). Mean length of stay was 5.2 days (2–10), and morphine equivalent requirement was 200 mg (47–460). There were no postoperative complications or deaths. After a mean follow-up of 40 months (3–99) there have been no recurrences. Our sublay repair of lumbar hernias with permanent suture fixation is safe and to date has resulted in no recurrences. Suture bone anchors ensure secure fixation of the mesh to the iliac crest and may eliminate a common area of recurrence.     

Treatment of large incisional abdominal wall hernias, using a modified preperitoneal prosthetic mesh repair

Very large and complex incisional hernias, especially those with loss of abdominal wall, can be a very interesting and perplexing problem, which present a particular challenge to the surgeon. The reported technique was developed and refined by one of our surgeons, between 1998 and 1999 for the repair of incisional hernias in a selected group of patients with large defects, often with a major loss of abdominal wall, overweight and previous attempts for incisional hernia repair. The technique involves a modified preperitoneal approach and was used on 43 eligible patients between 1999 and 2002. There were 30 females and 13 males at a mean age of 61 years. The median ASA score of the group was 2, with a mean BMI of 30.4 and a mean hernia surface area of 162 cm². One-third of the patients had one or more previous incisional hernia repair. Mean operating time was 190 min with an average hospital stay of 5.7 days. Postoperative complications occurred in 28% of the patients, most of which were minor and did not necessitate admission to the intensive care unit. None of the patients died. Wound infections occurred in 9.3%, was associated with an increased risk for cutaneous sinus formation, but not for mesh removal or hernia recurrence. A recurrence rate of 12.5% was found after a mean follow-up period of 46 months. We advocate this procedure for the repair of large, complex incisional hernias with loss of abdominal domain in patients with significant risk factors for recurrence.     

Laparoscopic ventral hernia repair with extraperitoneal mesh: surgical technique and early results

Laparoscopic repair of ventral abdominal wall hernias involves intraperitoneal placement of a mesh, which may lead to adhesion formation and bowel fistulation. The first series of selected patients with ventral abdominal wall hernias treated laparoscopically by extraperitoneal placement of a polypropylene mesh is presented. Thirty-four patients (24 women and 10 men; median age, 52 years [range, 34-70]) were selected from among 122 patients undergoing laparoscopic ventral hernia repair. Of these patients, 18 had a primary ventral abdominal wall hernia and 16 had an incisional hernia. After reduction of sac contents and adhesiolysis intraperitoneally, a large flap of peritoneum (with extraperitoneal fat, fascia, and posterior rectus sheath where present) was raised to accommodate a suitably sized polypropylene mesh, which was then covered again with the peritoneal flap at the end of the procedure. Intraoperatively, apart from circumcision of the hernial sac at the neck, a total of 24 iatrogenic peritoneal tears occurred in 20 patients, mainly at the site of the previous scar. In two patients, it was observed that greater than 25% of the mesh was exposed after the procedure. The median (+/-SD) duration of hospitalization postoperatively was 1 day (+/-0.56). One patient's hernia recurred 4 months after surgery, and one patient's infected mesh was removed 8 months after surgery. Laparoscopic extraperitoneal placement of a mesh is feasible and appears to be an advance over laparoscopic intraperitoneal mesh placement for ventral abdominal wall hernias in selected patients. However, longer follow-up and controlled clinical trials will be necessary before any firm conclusions can be drawn.     

Repair of large complex recurrent incisional hernias with retromuscular mesh and panniculectomy

BACKGROUND: Recurrent incisional hernia repair is associated with high recurrence and wound complication rates. METHODS: The clinical courses of patients who underwent recurrent incisional hernia repair via retromuscular mesh placement with concomitant panniculectomy at a university teaching hospital from 1999 to 2004 were reviewed retrospectively. Postoperative evaluation included a quality of life survey. RESULTS: Forty-seven patients (13 male, 34 female) with an average body mass index of 34.4 kg/m2, an average midline hernia defect of 31.4 cm, and at least 1 and on average 2.5 previous repair attempts underwent hernia repair. Wound infections occurred in 4 patients (8%) and seromas requiring aspiration occurred in 1 patient (2%). Four patients (8%) had re-recurrences of their hernias. All patients rated the postoperative appearance of their abdomen as at least satisfactory. CONCLUSIONS: Recurrent incisional hernia repair with a retromuscular mesh and panniculectomy has low recurrence and wound complication rates and excellent patient satisfaction.     

Abdominal lipectomy and mesh repair of midline periumbilical hernia after bariatric surgery: How to spare the umbilicus

Background: Abdominal lipectomy is becoming an increasingly common surgical procedure in patients with esthetic deformities resulting from massive weight loss induced by bariatric surgery. Sometimes a midline incisional hernia coexists with the pendulus abdomen. Herein presented is a technique to perform a retromuscular mesh repair of the incisional hernia while sparing the umbilicus. Methods: The abdominal lipectomy with concomitant retro-muscular mesh repair of a midline incisional hernia is done sparing the vascular supply of the umbilicus on one side only. Results: 5 consecutive women with pendulus abdomen resulting from bariatric surgery-induced massive weight loss and concomitant midline incisional hernia underwent abdominal lipectomy and incisional hernia mesh repair. Mean BMI was 28.6 kg/m² (range 26–35), one patient was a smoker, and another had type 2 diabetes requiring oral hypoglycemic agents. Two patients had had a previous incisional hernia repair with intraperitoneal mesh. One patient had partial necrosis of the umbilicus and another experienced necrosis of only the epidermis that recovered fully. Conclusions: The umbilicus can be safely spared during abdominal lipectomy with concomitant midline incisional hernia mesh repair. Recurrent incisional hernia and common risk factors for wound healing such as diabetes and obesity increase the risk of umbilical necrosis.     

Incisional abdominal hernia: the open mesh repair

BACKGROUND: Mesh techniques are the methods of choice for the repair of incisional hernias since these are due to the formation of unstable scar tissue. METHODS: We review the materials and techniques used in the repair of incisional hernias. We describe in detail the operative technique performed in our clinic, the pitfalls of the repair, and the overlap behind the xiphoid and the pubic bone. RESULTS: Polypropylene is the material widely used for open mesh repair. New developments have led to low-weight, large-pore polypropylene prostheses, which are adjusted to the physiological requirements of the abdominal wall and permit a proper tissue integration. These meshes provide the possibility of forming a scar net instead of a stiff scar plate and therefore help to avoid former known mesh complications. CONCLUSIONS: The ideal position for the mesh is the retromuscular sublay position where the force of the abdominal pressure holds the prosthesis against the deep surface of the muscles. The lowest incidence rates of recurrence have been reported for the retromuscular sublay repair; even after long-term follow-up recurrence rates of 10% are possible. Attaining such good results requires an adequate size of the mesh with sufficient overlap of at least 5-6 cm in all directions. Open mesh repair using modern low-weight polypropylene meshes in the retromuscular sublay technique offers excellent results for the treatment of incisional hernias.     

Concurrent Gastric Bypass and Repair of Anterior Abdominal Wall Hernias

Background: Many patients seeking surgical treatment for morbid obesity present with anterior abdominal wall hernias. Although principles of hernia repair involve a tension-free repair with the use of prosthetic mesh, there is concern about the use of mesh in gastric bypass surgery due to potential contamination with the contents of the gastrointestinal tract and resultant mesh infection. We report our series of patients undergoing Roux-en-Y gastric bypass (RYGBP) and simultaneous anterior abdominal wall hernia repair. Methods: All patients who underwent simultaneous RYGBP surgery and anterior abdominal wall hernia repair were reviewed. Results: 12 patients underwent concurrent RYGBP and anterior wall hernia repair. There were 5 women and 7 men with average age 54.9 ± 8.5 years (range 35 to 64) and average body mass index (BMI) 50.4 ± 10.3 kg/m² (range 38 to 70). Two open and 10 laparoscopic RYGBP operations were performed. Nine patients (75%) underwent incisional hernia repairs and 3 patients (25%) underwent umbilical hernia repair concurrent with gastric bypass. Average size of defect was 14.7 ± 13.4 cm². One patient had primary repair and 11 patients had prosthetic mesh repair: polypropylene in 3 patients (25%) and polyester in 8 patients (67%). With a 14.1 ± 9.3 month follow-up, there have been no mesh infections and 2 recurrences, one in the patient who underwent primary repair and one in a patient repaired with polyester mesh but with two previous failed incisional hernia repairs. Conclusion: Concurrent RYGBP and repair of anterior abdominal wall hernias is safe and feasible. In order to optimize success, tension-free principles of hernia repair with the use of prosthetic mesh should be followed since no mesh infections occurred in our series.     

Polypropylene-based composite mesh versus standard polypropylene mesh in the reconstruction of complicated large abdominal wall hernias: a prospective randomized study

Purpose

To compare polypropylene mesh positioned onlay supported by omentum and/or peritoneum versus inlay implantation of polypropylene-based composite mesh in patients with complicated wide-defect ventral hernias.

Methods

This was a prospective randomized study carried out on 60 patients presenting with complicated large ventral hernia in the period from January 2012 to January 2016 in the department of Gastrointestinal Surgery unit and Surgical Emergency of the Main Alexandria University Hospital, Egypt. Large hernia had an abdominal wall defect that could not be closed. Patients were divided into two groups of 30 patients according to the type of mesh used to deal with the large abdominal wall defect.

Results

The study included 38 women (63.3 %) and 22 men (37.7 %); their mean age was 46.5 years (range, 25–70). Complicated incisional hernia was the commonest presentation (56.7 %).The operative and mesh fixation times were longer in the polypropylene group. Seven wound infections and two recurrences were encountered in the propylene group. Mean follow-up was 28.7 months (2–48 months).

Conclusions

Composite mesh provided, in one session, satisfactory results in patients with complicated large ventral hernia. The procedure is safe and effective in lowering operative time with a trend of low wound complication and recurrence rates.
