Laparoscopic Repair of Left Lumbar Hernia After Laparoscopic Left Nephrectomy

Lumbar hernias, rarely seen in clinical practice, can be acquired after open or laparoscopic flank surgery. We describe a successful laparoscopic preperitoneal mesh repair of multiple trocar-site hernias after extraperitoneal nephrectomy. All the key steps including creating a peritoneal flap, reducing the hernia contents, and fixation of the mesh are described. A review of the literature on this infrequent operation is presented. Laparoscopic repair of lumbar hernias has all the advantages of laparoscopic ventral hernia repair.     

Day surgery for laparoscopic repair of abdominal wall hernias

Laparoscopic repair of abdominal wall hernias is still a controversial and nongeneralized therapeutic option. The aim of this paper is to evaluate the results of laparoscopic surgery on abdominal wall hernias at a day-surgery unit and to describe our procedure protocol. Prospective analysis of 300 patients undergoing laparoscopic surgery for abdominal wall hernias was conducted: 260 preperitoneal and 40 intraperitoneal. The patients' clinical features, hernia type, intraoperative and postoperative complications, and follow-up are studied for both types of surgery. All the patients receiving surgery with extraperitoneal laparoscopy were completed as a day-surgical procedure with a rate of conversion to open surgery of 2.3%. Twelve (30%) of the 40 patients operated on for ventral hernias using intraperitoneal laparoscopy required hospitalization: five for perioperative complications and seven for pain (16%). There was no case of infection or mesh rejection. The recurrence rates were 0.78% (two cases) for the inguinal hernias and 2.5% (one case) for the ventral hernias. In conclusion, laparoscopic repair of abdominal wall hernias in a day-surgery setting is an efficient alternative to open surgery. Electronic Publication     

The feasibility of adopting laparoscopic incisional hernia repair in general surgery practice: early outcomes in an unselected series of patients

A laparoscopic approach to incisional hernia repair has been shown to be safe and effective in selected patients. We report our early outcomes following laparoscopic ventral/incisional hernia repair (LVHR) in an unselected series of patients encountered in general surgery practice. All patients referred with incisional hernia were offered a laparoscopic repair using prosthetic mesh. Patients were not excluded from laparoscopic approach on the basis of age, previous surgery, defect size, intraperitoneal mesh, body mass index (BMI), comorbidities, or abdominal wall stomas. We followed 28 consecutive patients who underwent LVHR (17 primary, 11 recurrent hernias). Laparoscopic repair was completed in 27 patients with a mean operative time of 141.6 +/- 11.9 minutes. There were no intraoperative complications. The mean size of the abdominal wall defects was 153.4 +/- 27.5 cm and the mean mesh size was 349.2 +/- 59.1 cm. The mean hospital stay was 3.7 +/- 0.3 days. Nine patients developed large wound seromas; all spontaneously resolved. Our experience suggests that LVHR is feasible as a primary approach to most incisional hernias encountered in general surgery practice.     

Laparoscopic repair of incarcerated low spigelian hernia with transperitoneal PTFE DualMesh

There are different types of hernias that can develop at certain sites in the abdominal wall. Spigelian hernia (SH) is a protrusion of abdominal contents through a defect in the spigelian aponeurosis, in proximity to the external margin of the rectus muscle. Usually, abdominal wall hernia sac contains the omentum but may also contain small intestine that might become trapped in the hernia. When ischemia of herniated contents is suspected, urgent surgical treatment is advocated. Elective laparoscopic repair of SH is still under discussion. However, a recent randomized study comparing open and laparoscopic repair as elective treatment suggested that extraperitoneal laparoscopic repair is the technique that offers best results for the patients. Recent development of new biologic materials and technologies in laparoscopy has led to improved results. We report the successful repair of incarcerated low SH that was successfully managed by urgent laparoscopic intraperitoneal onlay polytetrafluoroethylene mesh hernioplasty.     

Is laparoscopic umbilical hernia repair with mesh a reasonable alternative to conventional repair?

BACKGROUND: Laparoscopic mesh repair has been advocated as treatment of choice for ventral hernias. The term "ventral hernia" refers to a variety of abdominal wall defects and laparoscopic papers have not reported defect specific analysis. The purpose of this study was to determine any advantages to laparoscopic mesh repair of umbilical hernias. METHODS: A retrospective review (January 1998 to April 2001) was made of patients undergoing umbilical hernia repair. Patients were categorized into three groups: laparoscopic repair with mesh, open repair with mesh, and open repair without mesh. Comparative analysis was performed. RESULTS: One-hundred and sixteen umbilical hernia repairs were performed in 112 patients: 30 laparoscopic mesh repairs, 20 open mesh repairs, and 66 open nonmesh repairs. The laparoscopic technique was used for larger defects and took more time with a trend toward fewer postoperative complications and recurrences. CONCLUSIONS: Laparoscopic umbilical hernia repair with mesh presents a reasonable alternative to conventional methods of repair.     

Triple-Step Laparoscopic Incisional Hernia Repair: Midline Suture Closure Supported by Dorsal Component Separation and Intraperitoneal Onlay Mesh Reinforcement

Incisional hernias remain a surgical challenge when balancing surgical morbidity, functional restoration, and risk of recurrence. Laparoscopic intraperitoneal onlay mesh (IPOM) placement reduces postoperative wound infections and allows fast patient recovery. Yet, current IPOM techniques do not achieve closure of the midline hernia gap, thereby increasing the risk of persistent mesh bulging with poor abdominal wall function. We propose a novel triple-step hernia repair technique that includes tension-free midline reconstruction. It is achieved through laparoscopic dorsal component separation and laparoscopic suture closure of the midline with a 1.0 polydioxanone suture sling. Combining dorsal abdominal wall component separation, a midline closure with adequate suture strength, and IPOM reinforcement merges the benefits of open and laparoscopic hernia repair. This triple-step technique allows static and functional laparoscopic abdominal wall reconstruction.     

Adhesions after laparoscopic inguinal hernia repair

Prosthetic mesh for laparoscopic inguinal hernia repair has become popular but the method of its placement is controversial. Mesh placed within the peritoneum may cause adhesion formation and further complications. The aim of this study was to examine the laparoscopic placement of a mesh, comparing intraperitoneal vs extraperitoneal insertion. In a porcine model (n=15) a polypropylene mesh was placed laparoscopically over the anterior abdominal wall. On the left side the mesh was stapled on the parietal peritoneum. On the right side the peritoneum was incised, an extraperitoneal space was dissected, the mesh was inserted, and the peritoneum was closed over it. The animals were maintained for 2 weeks. At postmortem there were adhesions in two of those placed extraperitoneally and five of those placed intraperitoneally (P=0.19, Fisher's exact test). The adhesions comprised fibrous peritoneal bands to loops of small intestine. Both methods of laparoscopic mesh placement were associated with a small but significant incidence of adhesion formation.Paper based on a communication to the European Association for Endoscopic Surgery in Cologne, Germany, June 1993     

从原发性腹壁疝的含义和特点谈微创术式进展

腹壁疝和原发性腹壁疝有不同的含义，本文原发性腹壁疝是指非手术引起的位于腹前外侧壁和后腹壁的腹外疝（不含腹股沟疝和股疝）。原发性腹壁疝患者无手术切口，更愿意接受微创治疗，其腹壁组织完整，也有利于微创新技术的开展。原发性腹壁疝的疗效显著优于切口疝。目前，微创术式众多，在原发性腹壁疝中可最大程度体现各自的优势。腹腔镜腹腔内补片修补术（IPOM）和微创非腹腔内补片修补术（MINIM）理念不同，技术互补，共同目标是追求微创和腹壁功能重建。MINIM的主要术式是各类腔镜腹膜外修补术（EER），大多从原发性腹壁疝起步，逐步发展并扩大其适应证。另一类术式是腔镜辅助肌前修补术（onlay），在中线位原发性腹壁疝中发挥特有的作用。脐疝、腹直肌分离、原发性耻骨上疝、半月线疝和原发性腰疝等是较常见的原发性腹壁疝，本文逐一讨论，阐述其定义、特点及微创术式的进展。     

Mobile caecum as a content in recurrent incisional hernia an incidental finding: A rare case report

IntroductionRecurrence in ventral hernia after laparoscopic repair is less as compared to conventional approach. Mobile caecum as a content of ventral hernia is a very rare entity. Standard treatment for mobile cecum is caecopexy using lateral peritoneal flap.Case reportA 40-year-old obese female, homemaker by occupation with a history of incisional hernia 2 year back and treated with intraperitoneal on lay mesh repair presented with swelling in the left lower abdomen for past 6 months. Radiological investigations revealed defect in left lower anterior abdominal wall with protruding bowel loops. Urgent exploratory Laparotomy revealed mobile segment of ileocecal junction in the hernial sac cavity. Caecopexy for the mobile caecum was done.DiscussionMobile caecum is due to embryological failure of fusion of right colonic mesentery with lateral peritoneal wall. Pre-operative diagnosis of mobile caecum is difficult to establish unless it presents as caecal volvulus Caecopexy using the lateral peritoneal flap is the standard of care.ConclusionMobile caecum can surprise the attending surgeon as a content of ventral hernia. Caecopexy using lateral peritoneal flap is the treatment of choice in all with a mobile caecum.     

Ventral hernia repair by the laparoscopic approach

An analysis of these results indicates that laparoscopic hernia repair can be performed safely by experienced laparoscopic surgeons, and with lower perioperative complication rates than for open hernia repair. Although the follow-up period for the laparoscopic repair is only 2 or 3 years, the recurrence rate is likely lower than with open repair. Most patients with ventral hernias are candidates for this laparoscopic repair if safe access and trocar placement can be obtained. The choice of mesh often provokes a debate among surgeons, but little practical difference in the results seems to exist between the two types of mesh available. Although the ePTFE mesh has a good theoretic basis for promoting tissue ingrowth on the parietal side of the mesh and minimizing adhesions to the bowel side of the mesh, data indicate that no difference in outcome exists related to adhesions or fistula formation (Tables 1 and 2), so surgeon preference and cost of the prosthesis should be the deciding variables. Fistulas are of concern because of the experience with mesh in the trauma patient and in the treatment of severe abdominal wall infections, when abdominal wall reconstruction often is performed in contaminated wounds in the acute phases and leaves the mesh exposed without soft tissue coverage. These conditions do not apply for most cases of elective hernia repair. Laparoscopic ventral hernia repair offers advantages over the conventional open mesh repair and may decrease the hernia recurrence rate to 10% to 15%. When properly performed, the laparoscopic approach does not and should not compromise the principles for successful mesh repair of ventral hernias.     

Laparoscopic repair of low abdominal wall hernias by tack fixation to the cooper ligament

Laparoscopic repair of low abdominal wall hernias present a challenge in mesh fixation, especially in the obese patient. Few reports have suggested repair by tack fixation to the Cooper ligament. Thirteen women, mean age 54.7 years, range 27 to 93 years, presented with 14 low abdominal wall hernias. Body mass index averaged 31.5, range 21 to 50.6. Twelve hernias were diagnosed clinically. Twelve hernias were incisional (7 midline, 5 lateral); 1 recurrent spegelian; and 1 primary midline. All hernias were repaired using laparoscopic transabdominal preperitoneal dissection, mesh fixation to an exposed Cooper ligament using the Protack, inferior edge or total mesh coverage by peritoneal-bladder flap elevation and fixation. Five small midline and lateral hernias were repaired transabdominal preperitoneally with polypropylene mesh. Nine large lower abdominal wall hernias (6 midline, 3 lateral) were repaired with Bard Composix E/X mesh. Follow-up averaged 17.5 months (range 5 to 30 mo). No hernias recurred. In conclusion, although suture versus tack fixation of mesh with laparoscopic repair of ventral hernias remains controversial, tack fixation of mesh to an exposed Cooper ligament in midline and lateral low ventral hernias has proven to be a successful repair. This technique is also efficacious in the obese patient.     

Laparoscopic ventral hernia repair: a new method for fixation of the mesh with sutures

BACKGROUND: Laparoscopic technique has proven to be a safe and feasible alternative to open mesh repair in the treatment of ventral hernias. It has been seen that the recurrence rate is the same as with open repair but with lesser morbidity. For the repair of ventral hernia with laparoscopy, mesh is placed intraperitoneally. The most common approach for intraperitoneal fixation of the mesh is by using a combination of transfascial sutures and tackers. This paper describes a new technique for intraperitoneal fixation of the mesh using sutures. SURGICAL TECHNIQUE: Adhesions to the previous scar are taken down. Mesh is anchored to the abdominal wall using 4 transfascial sutures at the 4 corners of the mesh. Fixation of the mesh between the transfascial sutures is performed by a new technique using continuous sutures. Fixation of the mesh with tacks is not required. CONCLUSIONS: This is a novel technique for fixation of the mesh to the abdominal wall intraperitoneally during laparoscopic repair of ventral hernia. Tackers are not required for the fixation of mesh.     

Intraperitoneal modification of the Rives-Stoppa repair for large incisional hernias

Introduction Recurrence rates for open repair of ventral/incisonal hernias historically range from 6% for the classic Rives-Stoppa repair to 35–45% for some of the techniques more commonly used in the United States. We report a modification to the classic Rives-Stoppa repair that allows intraperitoneal placement of the prosthetic, secured with a running suture. The abdominal muscles are closed over the mesh to protect it from any superficial wound problems that might develop and to restore normal architecture of the abdominal wall. Method A chart review was undertaken on all patients undergoing open ventral incisional hernia repair by a single surgeon from 2000 to 2006. All hernias were repaired with the intraperitoneal modification mimicking the principles of the Rives-Stoppa repair. Patient characteristics and operative and postoperative data were collected. Primary outcome was recurrence of hernia. Secondary outcomes were complications and rate of mesh infection. Results One hundred and fifteen patients were evaluated. Thirty-four patients had repair of recurrent ventral hernias. The average patient was obese, female, and 59 years old. Twenty-five patients used tobacco, eleven were diabetic, and seven used chronic corticosteroids. Meshes utilized included ePTFE, coated polyester, coated polypropylene, and biologic mesh. Average size of mesh was 465.4 cm². There were four recurrences (3.4%), three of which were due to mesh infection requiring mesh removal. Recurrence rate not secondary to mesh removal was 0.9%. Complications occurred in 26% with seroma formation being the most frequent (16%). Conclusion The intraperitoneal modification to the original Rives-Stoppa repair leads to a very low recurrence rate for large ventral hernia repairs with minimal complications and low rate of mesh infection.

Polyester-based mesh for ventral hernia repair: is it safe?

Introduction

The ideal prosthetic material for ventral hernia repair has yet to be described. Each prosthetic material has unique advantages and disadvantages in terms of tissue ingrowth, adhesion formation, and shrinkage profiles. Polyester-based mesh has shown minimal shrinkage and excellent tissue ingrowth in animal models. However, the macroporous, braided nature of this material has raised several concerns regarding the incidence of infections, fistulas, and bowel obstructions. We have reviewed our experience with polyester-based mesh for the repair of ventral hernias.

Methods

All patients undergoing ventral hernia repair at the Case Comprehensive Hernia Center at University Hospitals of Cleveland from December 2005 to April 2008 were included. Laparoscopic cases underwent intraperitoneal placement of a polyester-based mesh with a collagen hydrogel anti-adhesive barrier. The mesh was sized for at least 4 cm of fascial overlap, and transfascial fixation sutures and titanium spiral tacks were used routinely to secure the mesh to the abdominal wall. Those cases deemed inappropriate for laparoscopic ventral hernia repair underwent open repair. Open ventral hernia repairs were performed using a retrorectus repair, placing the mesh in an extraperitoneal position. Unprotected polyester mesh was used in these cases. Pertinent data included patient demographics, surgical details, postoperative outcomes, and long-term follow-up evaluation.

Results

During the study period 109 patients underwent ventral hernia repair with polyester mesh. Seventy-nine patients had a laparoscopic repair, and 30 patients had an open repair. The mean age was 57 years, with a mean body mass index of 33 kg/m², and American Society of Anesthesia score of 2.6. The patients had undergone 2.1 prior abdominal surgical procedures, and 42 patients had recurrent hernias. Surgical details for the laparoscopic repair and open repair were as follows: mean defect size, 116 versus 403 cm²; mesh size, 367 versus 1,055 cm²; and surgical times, 132 versus 170 minutes, respectively. The average hospital stay was 4.2 days for the laparoscopic repair and 5.8 days for the open repair groups. With a mean follow-up period of 14 months (range, 2-28 mo) in the laparoscopic repair group, 1 patient (1.4%) developed a mesh infection (with a history of a prior methicillin-resistant Staphylococcus aureus mesh infection), 1 patient (1.4%) developed a small-bowel obstruction remote to the mesh on re-exploration, and there were no fistulas. With a mean follow-up period of 11 months (range, 2-21 mo) in the open repair group, 3 wound infections (13%) occurred, 2 involved the mesh, which was salvaged with local wound care in 1, and required partial mesh resection in the other, and there were no bowel obstructions or fistulas during the follow-up evaluation.

Conclusions

This study shows that in this complex group of patients, polyester mesh placed during ventral hernia repair results in acceptable infection rates, and no direct bowel complications or fistulas. Given the macroporous nature of the mesh, each case of infection was treated successfully with local wound measures or partial mesh resection. Polyester-based meshes with an anti-adhesive barrier appear safe for intraperitoneal placement.     

Endoscopic totally preperitoneal ventral hernia repair

Background: In order to combine the advantages of a minimal invasive approach with a retromuscular mesh implantation, we developed an endoscopic totally preperitoneal approach for the treatment of ventral hernias. Methods: The surgical technique is described with the accent on preoperative marking of mesh surface, the retromuscular insertion of the first trocar, the extraperitoneal dissection, the reduction of the hernia sac, and the choice and insertion of the mesh. Results: Fifteen patients have been operated. Complete reduction of the hernia sac could be accomplished in five. In eight, the peritoneum was incised at the hernia neck. A polypropylene mesh was used in six cases. In the others, ePTFE or a composite mesh was used. Circumferential fixation with a tacker was performed. No major complications were seen. No mesh needed to be removed. One recurrence was seen 5.5 months postoperatively with a median follow-up period of 126 days. Conclusions: This new endoscopic technique takes advantage of immediate mesh fixation by the peritoneal sac and may avoid the potential complications related to the transabdominal approach and intraabdominal position of the mesh. A further long-term evaluation is necessary.     

Technique and early results of outpatient laparoscopic mesh onlay repair of ventral herniasrid=""id=""Presented to the Canadian Association of General Surgeons at the 67th Annual Meeting of the Royal College of Physicians and Surgeons of Canada, Toronto, Ontario, September 1998

Background: This report describes the technique and early results of a simple outpatient laparoscopic ventral hernia repair. Methods: Data were gathered prospectively for all laparoscopic ventral hernia repairs from January 1996 to December 1997 at a 228-bed hospital. Prolene mesh was stapled to the peritoneal surface of the abdominal wall, leaving sac in situ and mesh uncovered. Patients were seen by the operating surgeon within 2 months, and by an impartial surgeon (J.S.) after 3 to 14 months (average, 7 months; median, 6 months). Results: Repairs involved 44 hernias with orifice sizes 2 to 20 cm in diameter, and an average area of 20 cm². Of these 44 hernias, 36 were postoperative and 8 primary. Furthermore, 20% were recurrent hernias. There were four conversions. The outpatient rate was 98%, with one readmission for ileus. The early recurrence rate was 5%. Conclusions: Laparoscopic mesh onlay repair is a safe, easy, and effective procedure with minimal discomfort and a low early recurrence rate that can be performed safely on an outpatient basis.

Intraabdominal mesh prosthesis in a canine model

Laparoscopic inguinal hernia repair is still at an investigational stage, and varying methods have been described in the literature. These include the transabdominal preperitoneal approach, the intraperitoneal onlay mesh procedure, and the extraperitoneal approach. This study evaluates the differences in macroscopic adhesion formation between transabdominal preperitoneal mesh placement, intraperitoneal onlay mesh procedures, and extraperitoneal mesh placement in a canine model. The determination of microscopic tissue ingrowth and mesh incorporation was not a goal of this study. Operative sites utilizing mesh in a reperitonealized fashion resulted in less adhesion formation than did those sites where mesh was placed in an intraperitoneal manner using the onlay technique. Mesh placed in the extraperitoneal space without entering the peritoneal cavity did not exhibit any adhesion formation. Results favor the reperitonealization of intraabdominal mesh or mesh placement by an extraperitoneal approach.     

Use of polypropylene mesh for incisional hernia repair

Incisional hernia is an important complication of abdominal surgery. Procedures for the repair of these hernias with sutures and with mesh have been reported, but there is no consensus about which type of procedure is best. We have performed a retrospective analysis on 1014 patients operated on in our unit between 1994 and 2003 for simple or recurrent incisional hernias. The polypropylene mesh has been used in a number of 107 patients. The mesh has been placed either intraperitoneal, extraperitoneal/subfascial or onlay. Median follow-up was 36 months. There were 1 enterocutaneous fistula and 5 wound sinus developed. The mesh had to be removed in 6 cases. All of these complication developed when the mesh has been placed either extraperitoneal/subfascial or onlay. We note 5 recurrent incisional hernias after a period of up to 24 months. The recurrence rates after open mesh repair are less then after primary closure. The intraperitoneal use of polypropylene mesh with omental coverage is a good procedure with less complications.     

Laparoscopic treatment of ventral abdominal wall hernias: preliminary results in 100 patients.

OBJECTIVE: The laparoscopic treatment of eventrations and ventral hernias has been little used, although these hernias are well suited to a laparoscopic approach. The objective of this study was to investigate the usefulness of a laparoscopic approach in the surgical treatment of ventral hernias. METHODS: Between January 1994 and July 1998, a series of 100 patients suffering from major abdominal wall defects were operated on by means of laparoscopic techniques, with a mean postoperative follow-up of 30 months. The mean number of defects was 2.7 per patient, the wall defect was 93 cm2 on average. There were 10 minor hernias (<5 cm), 52 medium-size hernias (5-10 cm), and 38 large hernia (>10 cm). The origin of the wall defect was primary in 21 cases and postsurgical in 79. Three access ports were used, and the defects were covered with PTFE Dual Mesh measuring 19 x 15 cm in 54 cases, 10 x 15 cm in 36 cases, and 12 x 8 cm in 10 cases. An additional mesh had to be added in 21 cases. In the last 30 cases, PTFE Dual Mesh Plus with holes was employed. RESULTS: Average surgery time was 62 minutes. One procedure was converted to open surgery, and only one patient required a second operation in the early postoperative period. Minor complications included 2 patients with abdominal wall edema, 10 seromas, and 3 subcutaneous hematomas. There were no trocar site infections. Two patients developed hernia relapse (2%) in the first month after surgery and were reoperated with a similar laparoscopic technique. Oral intake and mobilization began a few hours after surgery. The mean stay in hospital was 28 hours. CONCLUSIONS: Laparoscopic technique makes it possible to avoid large incisions, the placement of drains, and produces a lower number of seromas, infections and relapses. Laparoscopic access considerably shortens the time spent in the hospital.     

Laparoscopic ventral hernia repair: an initial institutional experience

BACKGROUND: Ventral and incisional hernias remain a problem for surgeons with reported recurrence rates of 25-50% for open repairs. Laparoscopic approaches offer several theoretical advantages over open repairs. MATERIALS AND METHODS: All patients undergoing a laparoscopic ventral hernia repair from April to December 2000 were prospectively entered in a database. Patients underwent repair with expanded polytetrafluoroethylene dual mesh. Full-thickness abdominal wall nonabsorbable sutures and 5-mm tacks were placed circumferentially. RESULTS: Of 32 patients, 15 underwent incisional repair, 13 had repair of a recurrent incisional hernia, and 4 had repair of a primary abdominal wall defect. Two procedures [2/32; 6.3%] were converted to open, one for loss of abdominal domain and one for neovascularization due to cirrhosis. There were two early recurrences [2/30; 6.7%]. Both of these failures occurred in patients with hernia defects extending to the inguinal ligament, preventing placement of full-thickness abdominal wall sutures inferiorly. Average operating time was 128 +/- 42 min (range 37-225 min). Average length of stay was 1.8 days [range 0-7 days]. There were no transfusion requirements or wound infections. One patient underwent a small bowel resection after completion of repair. One patient required drainage of a seroma 4 weeks after the procedure. CONCLUSIONS: Laparoscopic ventral hernia repair can be safely performed with an acceptable early recurrence rate, operative time, length of stay, and morbidity. Securing the mesh with full-thickness abdominal wall sutures in at least four quadrants remains a key factor in preventing early recurrence.
