Laparoscopic Hernia Repair: a Two-Port Technique

Objective:

Various ventral and incisional hernia repair techniques exist and have largely replaced the open ones. The purpose of this study was to document the 2-port technique and demonstrate that it is feasible, efficient, and safe. To our knowledge, this is the largest report on this topic to date in the English-language literature.

Methods:

Forty patients with ventral hernias (VH) or incisional hernias (IH) underwent laparoscopic repair with a 2-port technique. The technique involves insertion of one 10-mm to 12-mm balloon port and one 5-mm port, usually on the left side as laterally as possible. A mesh is inserted through the balloon port site and secured to the abdominal wall by using either 4 peripheral or 1 central Prolene suture. Helical fasteners are used to attach the mesh to the abdominal wall.

Results:

Forty patients with 47 hernias underwent repair. Operating time ranged from 15 minutes to 70 minutes. Early complications were seen in 5 patients and included 1 small bowel enterotomy, 2 small bowel obstructions (SBO) with bowel adhering to the visceral side of the mesh, 1 wound infection, and 1 seroma. Late postoperative complications occurred in 8 patients (20%) who experienced persistent abdominal pain that resolved without any treatment. There was one recurrence during a mean follow-up of 23.5 months.

Conclusion:

Laparoscopic herniorrhaphy with the 2-port technique offers an efficient, safe, and effective repair for ventral and incisional hernias.     

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.     

Health-related quality of life in patients treated for incisional hernia with an onlay technique

Background  

An incisional hernia is a frequent complication of abdominal surgery. The repair of incisional hernias comes with a high risk of reherniation and serious complications. With the introduction of mesh repair, recurrence rates have decreased and subsequent clinical outcomes have improved. Whereas further research needs to be done to improve complication rates and recurrence, the focus has now been placed on quality-of-life outcomes in patients undergoing these repairs. The aim of this study was to investigate the long-term health-related quality of life (HRQL) of patients who were treated for incisional hernias using an onlay technique.     

Non-crosslinked porcine-derived acellular dermal matrix for the management of complex ventral abdominal wall hernias: a report of 45 cases

Purpose

Ventral abdominal wall hernias are common and repair is frequently associated with complications and recurrence. Although non-crosslinked intact porcine-derived acellular dermal matrix (PADM) has been used successfully in the repair of complex ventral hernias, there is currently no consensus regarding the type of mesh and surgical techniques to use in these patients. This report provides added support for PADM use in complex ventral hernias.

Methods

In a consecutive series of adult patients (2008–2011), complex ventral abdominal wall hernias (primary and incisional) were repaired with PADM by a single surgeon. Patient comorbidities, repair procedures, and postoperative recovery, recurrence, and complications were noted.

Results

Forty-four patients (mean age, 57.5 years) underwent 45 single-stage ventral abdominal wall hernia repairs (3 primary; 42 incisional). Previously placed synthetic mesh was removed in 17 cases. In 40 cases, primary fascial closure was achieved; in 5 cases, PADM was used as a bridge. Vacuum-assisted closure (VAC) was used for 38/45 cases: 19 closed incisions, 16 cases using the “French fry” technique, and 3 cases with open incisions. Mean hospital stay was 8.2 days (range, 3–32) and mean follow-up was 17 months (range, 1–48). There were 4 (8.9 %) hernia recurrences, 3 requiring additional repair and 1 requiring PADM explantation. There were 3 (6.7 %) skin dehiscences, 4 (8.9 %) deep wound infections requiring drainage, and 5 (11.1 %) seromas (4 self-limited, 1 requiring drainage).

Conclusions

Non-crosslinked intact PADM yielded favorable early outcomes when used to repair complex ventral abdominal wall hernias in high-risk patients.     

Laparoscopic transperitoneal sublay mesh repair: a new technique for the cure of ventral and incisional hernias

Background

Incisional hernia is a frequent complication after abdominal surgery. Today open sublay mesh repair and the laparoscopic intraperitoneal onlay mesh repair are the most widely used techniques for its cure. We developed a laparoscopic transperitoneal sublay mesh repair for the treatment of small- and medium-size ventral and incisional hernias. Outcomes of the new technique and the Rives–Stoppa repair were compared.

Methods

This prospective cohort study with a control group involved 93 patients. Between 2008 and 2010, 43 patients underwent the laparoscopic transperitoneal sublay mesh repair. During the same period of time, a control group of 50 patients underwent an open sublay repair after Rives and Stoppa. In 2011, all patients were invited for follow-up. This included pain assessments and physical examinations with use of ultrasound.

Results

The two groups were comparable in terms of patient characteristics and hernia data. The operating time was slightly longer for the laparoscopic technique. The hospital stay was shorter in the laparoscopy group. There was less chronic pain in the laparoscopy group, but this difference was not statistically significant. There was no significant difference in postoperative complications, use of analgetics, foreign body sensation, and paresthesia between the two groups. We found one long-term hematoma in the laparoscopy group and one seroma in the open group. In this series, there were no recurrences and no wound infections.

Conclusions

Our initial results indicate that the new laparoscopic transperitoneal sublay mesh repair is a safe and effective method for the treatment of small- and medium-size ventral and incisional hernias.     

New mesh shape and improved implantation procedure to simplify and standardize open ventral hernia repair: a preliminary report

Introduction  

Issues in ventral hernia repair are represented by the need for mesh fixation and how to assure a sufficient mesh overlap of the defect. Aiming to resolve these problems, this study describes a modified technique for ventral and incisional hernia repair based upon a newly developed mesh with a special design. This new type of implant allows broader coverage of the abdominal wall and results in tension- and fixation-free repair.     

Decreased re-operation rate for recurrence after defect closure in laparoscopic ventral hernia repair with a permanent tack fixated mesh: a nationwide cohort study

Purpose

To investigate whether defect closure in laparoscopic ventral hernia repair reduces the re-operation rate for recurrence compared with no defect closure.

Methods

Data were extracted from the Danish Ventral Hernia Database. Adults with an elective laparoscopic ventral hernia repair with tacks used as mesh fixation were included, if their first repair was between the 1st of January 2007 and the 1st of January 2017. Patients with defect closure were compared with no defect closure. Re-operation rates are presented as crude rates and cumulated adjusted re-operation rates. Sub-analyses assessed the effect of the suture material used during defect closure and also whether defect closure affected both primary and incisional hernias equally.

Results

Among patients with absorbable tacks as mesh fixation, 443 received defect closure and 532 did not. For patients with permanent tacks, 393 had defect closure and 442 did not. For patients with permanent tacks as mesh fixation, the crude re-operation rates were 3.6% with defect closure and 7.2% without defect closure (p?=?0.02). The adjusted cumulated re-operation rate was significantly reduced with defect closure and permanent tacks (hazard ratio?=?0.53, 95% confidence interval?=?0.28–0.999, p?=?0.05). The sub-analysis suggested that defect closure was only beneficial for incisional hernias, and not primary hernias. We did not find any benefits of defect closure for patients with absorbable tacks as mesh fixation.

Conclusion

This nationwide cohort study showed a reduced risk of re-operation for recurrence if defect closure was performed in addition to permanent tacks as mesh fixation during laparoscopic incisional hernia repair.

     

Laparoscopic Incisional Hernia Repair With Fibrin Glue in Select Patients

Background and Objective:

Laparoscopic treatment of incisional hernias can be performed using different types of fixation devices and prosthesis. We present a case series of 19 patients with incisional hernias with a diameter of <6cm, who underwent laparoscopic repair using Hi-tex dual-side mesh, positioned intraperitoneally, fixed to the abdominal wall by fibrin glue (Tissucol).

Methods:

Nineteen patients with incisional hernias <6cm in diameter were enrolled in this study and treated laparoscopically with Hi-tex and Tissucol. Surgical complications and patient outcomes were assessed with a clinical follow-up.

Results:

Laparoscopic repair of incisional hernias by using Hi-tex mesh affixed to the parietal wall with fibrin glue was feasible and easy in patients with parietal defects <6cm in diameter. Mean operating time was 30 minutes. Mean hospital stay was 1.5 days. Almost no postoperative pain, major surgical complications, seroma formation, relapses, or prosthesis infection occurred during a mean follow-up of 20 months.

Conclusions:

In select patients, Hi-tex mesh affixed using fibrin glue allows laparoscopic repair of incisional hernias with very good patient outcomes, especially in terms of postoperative pain and seroma formation.     

The comparison of heavyweight mesh and lightweight mesh in an incisional animal model

Purpose  

An incisional hernia may occur through the incision area following a surgical operation, through the trocar opening and even through drainage exit points. Various synthetic surgical meshes have recently been used for the surgical repair of incisional hernias. In this study, we analysed the burst strength forces of heavyweight mesh and lightweight mesh in an incisional animal model.     

Rives-Stoppa incisional hernia repair combined with laparoscopic separation of abdominal wall components: a novel approach to complex abdominal wall closure

Background  

The Rives-Stoppa incisional hernia repair is the gold standard for mesh repair of complex incisional hernias. The risk of infection can be reduced if fascia is closed over the prosthetic mesh. Fascial closure in large defects may require extensive dissection and can result in devascularization of the overlying skin and denervation of the abdominal wall musculature. Laparoscopic components separation minimizes these risks while facilitating anterior fascial closure. The combined technique of Rives-Stoppa repair augmented by laparoscopic separation of abdominal wall components has not previously been reported.     

Long-term Follow-up of Open and Laparoscopic Repair of Large Incisional Hernias

Background  

Long-term results after laparoscopic repair of large incisional hernias remain to be determined. The aim of this prospective study was to compare early and late complications between laparoscopic repair and open repair in patients with large incisional hernias.     

Results of prosthetic mesh repair in the emergency management of the acutely incarcerated and/or strangulated ventral hernias: a seven years study

Purpose

The aim of this prospective study was to present a 7-year experience with the use of prosthetic mesh repair in the management of the acutely incarcerated and/or strangulated ventral hernias.

Methods

Patients with acutely incarcerated and/or strangulated ventral hernias were treated by emergency repair of the hernia using an onlay Prolene mesh. The presence of non-viable intestine necessitating resection-anastomosis of the bowel was not considered a contraindication to the use of mesh.

Results

The present study included 80 patients. Their age ranged from 25 to 86 years with a mean of 56.1 ± 13.2 years. The hernia was para-umbilical in 71 patients (88.75 %), epigastric in 6 patients (7.5 %) and incisional in 3 patients (3.75 %). Eighteen patients (22.5 %) had recurrent hernias. Resection-anastomosis of non-viable small intestine was performed in 18 patients (22.5 %). There were 2 perioperative mortalities (2.5 %). Complications were encountered in 17 patients (21.3 %) and included wound sepsis in 9 patients (11.25 %), seroma formation in 5 patients (6.25 %), chest infection in 4 patients (5 %), deep vein thrombosis in 1 patient (1.25 %) and mesh infection in another patient (1.25 %). Follow-up duration ranged from 12 to 84 months with a mean of 49.9 ± 19.9 months. Only one recurrence was encountered throughout the study period.

Conclusions

The use of prosthetic mesh repair in the emergency management of the acutely incarcerated and/or strangulated ventral hernias is safe. The presence of non-viable intestine cannot be regarded as a contraindication for prosthetic repair.     

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.     

Long-Term Durability and Comfort of Laparoscopic Ventral Hernia Repair

Background:

Repair of ventral hernias, including primary ventral hernias and incisional ventral hernias, is performed in the United States 90,000 times per year. Open or traditional ventral hernia repairs involve the significant morbidity and expense of a laparotomy and a significant risk of recurrent herniation. Laparoscopic ventral hernia repair (LVHR) may offer a less-invasive alternative with shorter length of hospital stay, fewer cardiopulmonary complications, and low recurrence rates.

Methods:

225 patients underwent laparoscopic ventral hernia repairs in which carboxymethylcellulose-sodium hyaluronate coating (Sepramesh, Davol, Providence, RI) was used primarily. All cases were included prospectively from the study period of 2002 through 2009. Patient characteristics were recorded, and follow-up analysis was performed over a period of 42 mo following surgery. Recurrence, reoperations, and all complications were recorded. Mesh awareness and mesh-related pain were assessed using the hernia-specific Carolinas Comfort Scale (CCS) instrument, completed by 72 patients.

Results:

Over 42 mo of follow-up, 2 ventral hernias have recurred, and no long-term bowel erosion or fistulization has occurred. Little or no mesh-related symptoms were reported, and mean scores for mesh awareness and mesh pain were 3.6 and 3.2, respectively, on a scale from 0–40 (lower scores signify less pain or awareness). Two serious early complications occurred related to intestinal ileus and metal tacks producing intestinal perforation, and this led to a change in the tacking devices used.

Conclusions:

LVHR with carboxymethylcellulose-sodium hyaluronate coating (Sepramesh) is safe and effective. Complications are rare, the repair is durable, and long-term results are good with rare recurrences, low awareness of mesh, and little pain. Technical lessons include use of at least one transfascial suture and the avoidance of metal tacks for fixation.     

Evaluation of crosslinked and non-crosslinked biologic prostheses for abdominal hernia repair

Introduction  

Abdominal wall defects and incisional hernias represent a challenging problem. Currently, several commercially available biologic prostheses are used clinically for hernia repair. We compared the performance and efficacy of two non-crosslinked meshes in ventral hernia repair to two crosslinked prostheses in a rodent model.     

Initial experience with transvaginal incisional hernia repair

Introduction

Natural orifice surgery has evolved from a preclinical setting into a common occurrence at the University of California San Diego (UCSD). With close to 40 transvaginal cases, we have become comfortable with this technique and are exploring other indications. One of the perceived advantages in natural orifice surgery is the potential reduction in the incidence of hernia formation. Patients with abdominal wall hernias may be at increased risk of forming additional hernias at incision sites. In addition, patients with recurrent incisional hernias may, likewise, be at increased risk. We believe that reducing or eliminating abdominal wall incisions may be of benefit in the repair of abdominal wall hernias. Here, we describe what we believe to be the first natural orifice transluminal endoscopic surgical (NOTES) approach to the repair of an abdominal wall hernia.

Methods

The patient is a 38-year-old female with a painful recurrent umbilical hernia, previously repaired 8 years prior with a polypropylene-based mesh. The patient underwent a transvaginal recurrent umbilical hernia repair with one other 5-mm port in the abdomen for safety.

Results

The patient had no intraoperative or postoperative complications. At 5 months follow up, the patient had no complaints, no evidence of hernia recurrence, and was very pleased with her result.

Conclusions

The repair of primary and incisional hernias of the ventral abdominal wall via a transvaginal approach is technically feasible, and the result of our initial case was exceptional. However, there are still significant obstacles which must be addressed before this approach can be widely utilized. These obstacles include safe entrance into the abdominal cavity via a transvaginal approach, the proper mesh to be placed during the repair, and the risk of infection.     

Laparoscopic ventral/incisional hernia repair: a single centre experience of 1,242 patients over a period of 13 years

Background and purpose  

Laparoscopic technique is now well established for ventral/incisional hernia repair. However several issues such as optimal fixation technique, occult hernias, management of inadvertent enterotomies, postoperative seromas and recurrence require appraisal.     

Impact of pressure and gas type on adhesion formation and biomaterial integration in laparoscopy

Background  

Laparoscopic mesh repair of inguinal and incisional hernias has been widely adopted. Nevertheless, knowledge about the impact of pneumoperitoneum on mesh integration is rare. The present study investigates pressure and gas-dependent effects of pneumoperitoneum on adhesion formation and biomaterial integration in a standardized animal model.     

Laparoscopic Incisional Hernia Repair in Liver Transplant and Other Immunosuppressed Patients

We report the early results of laparoscopic incisional hernia repair in a small group of immunosuppressed patients and compare these results with a cohort of patients with open repair. We describe a modification used to secure the cephalad portion of the Gore-Tex mesh in high epigastric incisional hernias often encountered after liver transplantation. Data were gathered retrospectively for all incisional hernia repairs by our group from March 1996 to January 2001. Twelve of 13 attempted patients had successful completion of their laparoscopic hernia repairs with no reported recurrences to date. Two of these procedures were performed for recurrent hernias. We completed nine of nine attempted laparoscopic hernia repairs in liver transplant patients with epigastric incisional hernias. We repaired two of three attempted lower midline incisional hernias in renal disease patients. One of these patients was soon able to reuse his peritoneal dialysis catheter. A total of 15 patients, 12 with liver transplants, underwent open repair of their incisional hernias. These patients had seven recurrences and/or serious mesh infections with five patients electing repeated operations. In our initial series, laparoscopic mesh repair of incisional hernias is practical and safe in the abdominal organ transplant population with a low incidence of early recurrence and serious infections.     

Watchful waiting as a treatment strategy for patients with a ventral hernia appears to be safe

Purpose

Due to risks of postoperative morbidity and recurrence some patients with a ventral hernia are not offered surgical repair. There is limited data on the rate and consequences of a watchful waiting (WW) strategy for these patients. The objective of this cohort study was to analyse outcomes for patients with a ventral hernia who underwent watchful waiting, in terms of later requirement for hernia repair.

Methods

All patients (≥18 years) electively referred to our out-patient clinic from 1 January 2009 to 1 July 2014 with incisional, umbilical or epigastric hernia were included. Information on patient characteristics and whether patients underwent WW or surgery was obtained from hospital files and the Danish National Patient Register. A 100 % follow-up was obtained.

Results

The analyses comprised 569 patients with incisional hernia (WW = 58.1 %) and 789 patients with umbilical/epigastric hernia (WW = 43.2 %). Kaplan–Meier analyses estimated that the probability for patients who underwent watchful waiting to receive later surgical repair was 19 % for incisional hernias and 16 % for umbilical/epigastric hernias after 5 years. The probability of requiring emergency repair when in the WW group was 4 % for both incisional and umbilical/epigastric hernias after 5 years. There were no significant differences in 30-day readmission, reoperation or mortality rates between the WW patients who later underwent elective hernia repair and patients who were initially offered surgery (p > 0.05), for both incisional and umbilical/epigastric hernias.

Conclusions

Watchful waiting appears to be a safe strategy in the treatment of incisional, umbilical and epigastric hernias.
