Long-term complaints after elective repair for small umbilical or epigastric hernias

Purpose

Elective repair for umbilical or epigastric hernia is a frequent minor surgical procedure. Several studies have demonstrated chronic pain after groin hernia repair but long-term complaints have been only scarcely studied. This study was undertaken to investigate long-term pain and discomfort after open repair for small umbilical or epigastric hernias.

Methods

This is a retrospective study with prospective long-term follow-up. Only elective primary umbilical or epigastric hernias with an open mesh or sutured repair were included. A structured follow-up questionnaire was sent to all patients regarding verbal rating scores (VRS) of pain and discomfort (no, little, moderate, or severe) and recurrence. Patients with suspected recurrence were clinically examined.

Results

There were 139 eligible patients, and 132 patients answered the questionnaire (95 % response rate). The median follow-up time was 36 months (range 15–85), and defect size was 1.0 cm (0.2–8.0). Sixteen patients reported moderate or severe pain and/or discomfort (12 %, 95 % confidence interval (CI): 6–18). The cumulated risk of recurrence was 11.5 %. Of the 15 patients with clinical recurrence or reoperation for recurrence, 5 patients reported moderate/severe complaints (31 %) whereas 11 of the remaining 116 patients with no recurrence (10 %) reported moderate/severe complaints (P = 0.014).

Conclusion

Surprisingly, many patients complained about pain and discomfort 3 years after elective repair for a small umbilical or epigastric hernia.     

Outcomes After Emergency Versus Elective Ventral Hernia Repair: A Prospective Nationwide Study

Background

Early surgical results after emergency repairs for the most frequent ventral hernias (epigastric, umbilical, and incisional) are not well described. Thus, the aim of present study was to investigate early results and risk factors for poor 30-day outcome after emergency versus elective repair for ventral hernias.

Methods

All patients undergoing epigastric, umbilical, or incisional hernia repair registered in the Danish Hernia Database during the period 1 January 2007 to 31 December 2010 were included in the prospective study. Follow-up was obtained through administrative data from the Danish National Patient Register.

Results

In total, 10,041 elective and 935 emergency repairs were included. The risk for 30-day mortality, reoperation, and readmission was significantly higher (by a factor 2–15) after emergency repairs than after elective repairs (p ≤ 0.003). In addition, there were significantly more patients with concomitant bowel resection after emergency repairs than after elective repairs (p < 0.001). Independent risk factors for emergency umbilical/epigastric hernia repair were female gender, older age, hernia defects >2–7 cm, and repair for a primary hernia (vs recurrent hernia) (all p < 0.05). Independent risk factors for emergency incisional hernia repair were female gender, increasing age, and hernia defects ≤7 cm (all p < 0.05).

Conclusions

Emergency umbilical/epigastric or incisional hernia repair was beset with up to 15-fold higher mortality, reoperation, and readmission rates than elective repair. Older age, female gender, and umbilical hernia defects between 2 and 7 cm or incisional hernia defects up to 7 cm were important risk factors for emergency repair.     

Chronic complaints after simple sutured repair for umbilical or epigastric hernias may be related to recurrence

Purpose

Umbilical and epigastric hernia repairs are minor, but are commonly conducted surgical procedures. Long-term results have only been sparsely investigated. Our objective was to investigate the risk of chronic complaints after a simple sutured repair for small umbilical and epigastric hernias.

Methods

A retrospective cohort study with a 5-year questionnaire and clinical follow-up was conducted. Patients undergoing primary elective, open non-mesh umbilical or epigastric sutured hernia repair were included. Patients completed a structured questionnaire regarding chronic complaints during work and leisure activities using a verbal rating scale. The primary outcome was chronic complaints.

Results

A total of 295 patients were included for analysis after a median of 5.0-year (range 2.8–8.0) follow-up period. Follow-up results were achieved from 262 of the included patients (90 % response rate). Up till 5.8 % of the patients reported moderate or severe pain and discomfort. Work and leisure activities were restricted in 8.5 and 10.0 % of patients, respectively. Patients with chronic complaints had a higher incidence of recurrence (clinical and reoperation), than patients with none or mild complaints (78.6 vs. 22.2 % (P?<?0.001)). The recurrence rate was significantly higher after a repair with absorbable suture (20.1 %) compared with non-absorbable suture repair (4.2 %) (P?<?0.001).

Conclusion

We found that chronic complaints after a simple sutured umbilical or epigastric repair was in the level of 5.5 % and could in part be explained by recurrence. Furthermore, absorbable suture should be omitted to reduce risk of recurrence.     

Nationwide prospective study on readmission after umbilical or epigastric hernia repair

Purpose

The primary aim of the present study was to investigate risk factors for readmission after elective umbilical and epigastric hernia repair and secondarily to evaluate causes for readmission.

Methods

All patients with elective umbilical or epigastric hernias registered in The Danish Hernia Database during January 2007–January 2011 were included. A 100 % 30-day follow-up was obtained by merging with administrative data from The Danish National Patient Register.

Results

A total of 6,783 umbilical and epigastric hernia repairs were included (open = 5,634; laparoscopic = 1,149). Readmissions caused by surgical and medical complications related to the hernia repair were observed in 3.6 and 1.5 % of patients, respectively. Surgical complications were mainly due to pain and wound complications, whereas medical complications were mainly cardiovascular, pulmonary, and renal complications. There were no significant differences in surgical or medical complication rates and in risk factors for readmission between open and laparoscopic repair, P ≥ 0.229. After open repair, independent risk factors for readmission were umbilical hernia repair (vs epigastric repair) (OR = 1.5, 95 % CI 1.1–2.1), hernia defects >2 cm (OR = 1.7, 95 % CI 1.2–2.5), mesh reinforcement (OR = 1.3, 95 % CI 1.0–1.7), and tacked mesh fixation (OR = 2.6, 95 % CI 1.1–6.0). After laparoscopic repair, female gender was the only independent risk factor for readmission (OR = 1.7, 95 % CI 1.1–2.7).

Conclusion

The risk for 30-day readmission after umbilical or epigastric hernia repairs was mainly because of surgical complications. Open mesh repair reduced the risk for readmission in open repairs; no specific approach was found to reduce readmission after laparoscopic repair.     

Single-incision pediatric endosurgical epigastric hernia repair

Purpose

Epigastric hernias represent about 4 % of all abdominal hernias in children and require surgical repair. Traditionally, these hernias are repaired by an open surgical technique. More recently, laparoscopic epigastric hernia repairs have been described using two trocars in the upper abdomen. In this paper, we describe a novel single-incision pediatric endosurgical (SIPES) technique.

Methods

Patients with symptomatic epigastric hernias that were deemed to be too far superior to be repaired with an open technique through an umbilical incision were selected for SIPES repair. Two trocars (5 and 3 mm) were introduced through a single umbilical incision and the hernia repair was performed using looped 4-0 polypropylene sutures introduced through a 17-gage spinal needle in a lasso technique.

Results

Five girls (age 4.4–12.6, median 6.4 years) underwent single-incision endosurgical epigastric hernia repair. The mean operative time was 25 ± 6 min, and there were no intraoperative complications. All patients were discharged home from the recovery room on the day of surgery. All patients were followed up 2–3 weeks after the operation, with no recurrence and excellent cosmetic results.

Conclusions

The described SIPES technique offers a virtually scarless, quick, and simple option for the repair of symptomatic epigastric hernias that can be performed with standard laparoscopic equipment.     

Single centre observational study to evaluate the safety and efficacy of the Proceed™ Ventral Patch to repair small ventral hernias

Background

There is evidence that mesh repair for primary umbilical hernias results in less recurrences and similar wound complication rates compared to tissue repair. In recent years, several mesh devices for the repair of small ventral hernias have been developed, but some reports have been published on serious complications and adverse effects encountered with those mesh devices.

Methods

The Proceed? Ventral Patch (PVP?) is a partially absorbable lightweight polypropylene mesh. We introduced PVP? in our department in April 2009 and collected patient data and outcome in an observational study of 101 consecutive patients until December 2011 (Clinical.Trials.gov: NCT01307696). In addition to the routine control 3 weeks postoperative, prospective follow-up included a questionnaire, clinical investigation and ultrasound after 12 months.

Results

The study included 91 primary (76 umbilical/15 epigastric) and 10 incisional ventral hernias (including 6 trocar hernias). In all patients a PVP? with a diameter of 6.4 cm was used. Wound problems were the most frequent complication (n = 18). Follow-up of at least 12 months was achieved in 98 patients (97 %) and the mean follow-up time was 15.9 months. Follow-up by clinical examination diagnosed a recurrence in 11/92 patients (12.0 %). Only four patients were aware of their recurrent hernia, the seven others reported no problems in the questionnaire. The additional ultrasound performed did not reveal recurrences that were not already diagnosed by clinical examination. In five patients a reoperation for repair of the recurrence was performed (reoperation rate 5/98 = 5.1 %). Hernia defect size (p = 0.032) and type of hernia (p = 0.029) were found to be a significant risk factors for development of a recurrent hernia (Fisher’s exact test). Hernia size was a significant risk factor both in a univariate (p = 0.005) and in a multivariate Cox model (p = 0.017). Incisional hernia was of borderline significance in a univariate (p = 0.047) and in a multivariate Cox model (p = 0.08).

Conclusion

Intensive clinical follow-up yields a high percentage (12.0 %) of clinically proven, but often asymptomatic recurrences after repair of small ventral hernias with the PVP?. Reoperation rate for recurrence was 5.1 %. Hernia defect size is a significant risk factor for recurrence. Therefore, we recommend using the PVP? only for primary ventral hernias smaller than 2 cm. For larger or incisional hernias other techniques allowing the use of larger meshes is advocated.     

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.

     

Proposed technique for open repair of a small umbilical hernia and rectus divarication with self-gripping mesh

Introduction

There are a group of patients in which umbilical or epigastric hernias co-exist with rectus divarication. These patients have weak abdominal musculature and are likely to pose a higher risk of recurrence following umbilical hernia repair. We would like to describe a technique for open repair of small (<4 cm) midline hernias in patients with co-existing rectus divarication using self-adhesive synthetic mesh. The use of a self-adhesive mesh avoids the need for suture fixation of the mesh in the superior portion of the abdomen, allowing for a smaller skin incision.

Results

In 173 patients, preperitoneal self-fixating mesh has been used for the repair of midline hernias <4 cm in diameter. In 58 of these patients, the mesh was extended superiorly to reinforce a concurrent divarication.

Discussion

The described technique offers a simple option for open repair of small midline hernias in patients with co-existing rectus divarication, to decrease the risk of upper midline recurrence in an at-risk patient group. This initial case series is able to demonstrate a suitably low rate of recurrence and complications.

     

Current national practice patterns for inpatient management of ventral abdominal wall hernia in the United States

Background

The health-care burden related to ventral hernia management is substantial, with more than 3 billion dollars in expenditures annually in the US. Previous studies have suggested that the utilization of laparoscopic repair remains relatively low although national volume estimates have not been reported. We sought to estimate the inpatient national volume of elective ventral hernia surgery and characterize the proportion of laparoscopic versus open operations.

Methods

We analyzed data from the Nationwide Inpatient Sample to identify adults with a diagnosis of an umbilical, incisional, or ventral hernia who underwent an elective inpatient repair between 2009 and 2010. Cases that involved other major abdominal or pelvic operations were excluded. Covariates included patient demographics, surgical approach, and use of mesh. National surgical volume estimates were generated and length of stay and total hospital charges were compared for laparoscopic versus open repairs.

Results

A total of 112,070 ventral hernia repairs were included in the analysis: 72.1 % (n = 80,793) were incisional hernia repairs, while umbilical hernia repairs comprised only 6.9 % (n = 7,788). Laparoscopy was utilized in 26.6 % (n = 29,870) of cases. Mesh was placed in 85.8 % (n = 96,265) of cases, including 49.3 % (n = 3,841) of umbilical hernia repairs and 90.1 % (n = 72,973) of incisional hernia repairs. Length of stay and total hospital charges were significantly lower for laparoscopic umbilical, incisional, and “other” ventral hernia repairs (p values all <0.001). Total hospital charges during this 2-year period approached 4 billion dollars ($746 million for laparoscopic repair; $3 billion for open repair).

Conclusions

Utilization of laparoscopy for elective abdominal wall hernia repair remains relatively low in the US despite its excellent outcomes. Given the substantial financial burden associated with these hernias, future research focused on preventing the development and optimizing the surgical treatment of ventral abdominal wall hernias is warranted.     

Evaluation of surgical outcomes of retro-rectus versus intraperitoneal reinforcement with bio-prosthetic mesh in the repair of contaminated ventral hernias

Introduction

Hernia repairs in contaminated fields are often reinforced with a bioprosthetic mesh. When choosing which of the multiple musculofascial abdominal wall planes provides the most durable repair, there is little guidance. We hypothesized that the retro-rectus plane would reduce recurrence rates versus intraperitoneal placement due to greater surface area contact of mesh with well-vascularized tissue.

Methods

Forty-nine of the 80 patients in an ongoing, prospective, multicenter study of contaminated ventral hernia repairs (RICH study, NCT00617357) achieved fascial closure after musculofascial centralization and reinforcement with non-crosslinked porcine acellular dermal matrix (Strattice?, LifeCell, Branchburg, NJ) and were retrospectively analyzed. The Strattice was placed in the retro-rectus position in 23 patients and in the intraperitoneal position in 26.

Results

Subjects were comparable in age, obesity, prior wound infection, presence of a stoma, and infected mesh removal (p > 0.05). More smokers were present in the intraperitoneal group (p = 0.02). Retro-rectus defects were significantly wider and had larger area than the intraperitoneal repairs. At the 1-year follow-up, 44 (90%) of patients were available for review. There was no difference in wound infections, seromas, or hematomas. Recurrent hernias were identified in 10% of retro-rectus repairs and 30% of intraperitoneal repairs (p = 0.14).

Conclusions

In this retrospective analysis of a prospective multicenter study of large, contaminated ventral hernias, despite a larger hernia defect in the retro-rectus group, placement of the mesh in the retro-rectus compartment resulted in a similar recurrence rate to intraperitoneal mesh placement. Ongoing evaluation is important to establish longer-term outcomes and the validity of these findings.     

Single-Center Experience With Parastomal Hernia Repair Using Retromuscular Mesh Placement

Background

Parastomal hernias (PHs) are frequent complications of enterostomies. We aimed to evaluate our outcomes of open PH repair with retromuscular mesh reinforcement.

Methods

From 2006 to 2013, 48 parastomal hernias were repaired in 46 consecutive patients undergoing open retromuscular repair. Surgical technique included stoma relocation, retromuscular dissection, posterior component separation, and retromuscular mesh placement. All stomas were prophylactically reinforced with cruciate incisions through mesh. Main outcome measures included demographics, perioperative details, wound complications (classified according to the CDC guidelines), and recurrences.

Results

There were 24 male and 22 female patients with a mean age of 61.8 and body mass index (BMI) of 31.7 kg/m². Twenty-four patients had recurrent PH with an average of 3.8 prior repairs. Ostomies included 18 colostomies, 20 ileostomies, and 10 ileal conduits. Thirty-two patients had a concurrent repair of a midline incisional hernia. All patients underwent mesh repair with either biologic (n?=?29), lightweight polypropylene (n?=?15), or absorbable synthetic mesh (n?=?2). There were 15 superficial surgical site infections (SSIs) and 6 deep SSIs. There was one case of an ischemic ostomy requiring surgical revision. No mesh grafts required removal and there were no mesh erosions. At a mean follow-up time of 13 months, five patients (11 %) developed a recurrence; three patients required re-repair.

Conclusion

In this largest series of complex open repairs with retromuscular mesh reinforcement and stoma relocation, we demonstrate that this results in an effective repair. This technique should be considered for complex parastomal hernia repair.     

Lower reoperation rates with the use of fibrin sealant versus tacks for mesh fixation

Background

Groin hernia repair may be associated with long-term complications such as chronic pain, believed to result from damage to regional nerves by tissue penetrating mesh fixation. Studies have shown that mesh fixation with fibrin sealant reduces the risk of these long-term complications, but data on recurrence and reoperation rates after the use of fibrin sealant compared with tacks are not available. This study aimed to determine whether fibrin sealant is a safe and feasible alternative to tacks with regard to reoperation rates after laparoscopic groin hernia repair.

Methods

The current study compared reoperation rates after laparoscopic groin hernia repair between fibrin sealant and tacks used for mesh fixation. The study used data collected prospectively from The National Danish Hernia Database and analyzed 8,314 laparoscopic groin hernia repairs for reoperation rates. Mesh fixation was performed with fibrin sealant (n = 784) or tacks (n = 7,530).

Results

The findings showed a significantly lower reoperation rate for the fibrin sealant than for the tacks (0.89 vs 2.94 %, p = 0.031). The median follow-up period was 17 months (range, 0–44 months) for the fibrin sealant group and 21 months (range, 0–44 months) for the tacks group.

Conclusions

Fibrin sealant was superior to tacks for mesh fixation in laparoscopic groin hernia repair with regard to reoperation rates. The study could not differentiate between different hernia defect sizes, and future studies should therefore explore whether the superior effect of fibrin sealant applies for all hernia types and sizes.     

Closure versus non-closure of hernia defect during laparoscopic ventral hernia repair with mesh

Purpose

Laparoscopic ventral hernia repair with mesh versus laparoscopic ventral hernia defect closure with mesh reinforcement. The primary end-point was recurrence.

Methods

Retrospective review of patients who underwent laparoscopic ventral hernia repair for small- and medium-sized hernias between July 2000 and September 2011. These patients were divided: (1) repair with mesh alone (non-closure group) and (2) those with hernia defect closure and mesh reinforcement (closure group). The closure group was further divided by technique: percutaneous versus intracorporeal closure of the defect.

Results

128 patients were studied: 93 patients (72.66 %) in the non-closure group and 35 patients (27.34 %) in the closure group. Follow-up was available in 105 patients (82.03 %) at a mean of 797.2 days (range 7–3,286 days). In the non-closure group there were 14 patients (15.05 %) with postoperative complications and 8 patients (22.86 %) in the closure group, four of which were seromas. Fourteen patients (19.18 %) developed recurrent hernias in the non-closure group with an average time to presentation of 23.17 months (range 5.3–75.3). Two patients (6.25 %) developed recurrent hernias in the percutaneous group with an average time to presentation of 12.95 months (range 9.57–16.33). There have been no recurrences in patients whose defect was closed intracorporeally.

Conclusion

Although our study demonstrated a difference in recurrence rates of 19.18 % in the non-closure group versus 6.25 % in the closure group, the difference did not reach statistical significance. A larger series with longer follow-up may demonstrate clinical significance.     

Assessing the impact of short-term surgical education on practice: a retrospective study of the introduction of mesh for inguinal hernia repair in sub-Saharan Africa

Purpose

Inguinal hernia repair is the most common general surgery operation performed globally. However, the adoption of tension-free hernia repair with mesh has been limited in low-income settings, largely due to a lack of technical training and resources. The present study evaluates the impact of a 2-day training course instructing use of polypropylene mesh for inguinal hernia repair on the practice patterns of sub-Saharan African physicians.

Methods

A surgical training course on tension-free mesh repair of hernias was provided to 16 physicians working in rural Ghanaian and Liberian hospitals. Three physicians were requested to prospectively record all their inguinal hernia surgeries, performed with or without mesh, during the 14-month period following the training. Demographic variables, diagnoses, and complications were collected by an independent data collector for mesh and non-mesh procedures.

Results

Surgery with mesh increased significantly following intervention, from near negligible levels prior to the training to 8.1 % of all inguinal hernia repairs afterwards. Mesh repair accounted for 90.8 % of recurrent hernia repairs and 2.9 % of primary hernia repairs after training. Overall complication rates between mesh and non-mesh procedures were not significantly different (p = 0.20).

Conclusions

Three physicians who participated in an intensive education course were routinely using mesh for inguinal hernia repair 14 months after the training. This represents a significant change in practice pattern. Complication rates between patients who underwent inguinal hernia repairs with and without mesh were comparable. The present study provides evidence that short-term surgical training initiatives can have a substantial impact on local healthcare practice in resource-limited settings.     

Improved Outcomes in the Management of High-Risk Incisional Hernias Utilizing Biological Mesh and Soft-Tissue Reconstruction: A Single Center Experience

Introduction

Repair of incisional hernias is complex in the setting of previous/current infection, loss of domain and bowel involvement, and is often on the background of significant co-morbidities. Reported repair techniques are associated with significant morbidity and led our unit to develop a novel technique for complex incisional hernia repair.

Methods

A retrospective case notes review of all high-risk (Ventral Hernia Working Group grade 2–4) incisional hernia repairs was undertaken. Standardized repair involved resection of attenuated soft tissue and hernia sac (bioburden reduction), component separation (where necessary), intra-peritoneal Strattice? biological mesh insertion, midline fascial closure, and soft-tissue reconstruction, performed in combination with a plastic surgeon as a single-stage procedure.

Results

A total of 58 patients underwent hernia repair between February 2009 and September 2012 (median age 59 years; 59 % female). Eleven patients (19 %) were grade 4, 19 (33 %) were grade 3, and 28 (48 %) were grade 2. Nineteen (33 %) were recurrent hernias, and midline fascial closure was achieved in 52 (90 %). Early complications included 15 (26 %) surgical-site occurrences, three (5 %) respiratory complications, two (3 %) cardiac complications, and two (3 %) urinary tract infections. Follow-up has revealed three (5 %) asymptomatic hernia recurrences and no patients requiring mesh explantation.

Conclusions

This technique was associated with a low risk of surgical site occurrences and hernia recurrence, with no requirements for mesh explantation. Repair of such complex incisional hernias remains challenging, and further randomized controlled trials are required to elucidate the optimal method of closure and mesh type.     

Acceptable nationwide outcome after paediatric inguinal hernia repair

Purpose

The primary objective was to describe 30-day outcomes after primary inguinal paediatric hernia repair.

Methods

Prospectively collected data from the National Patient Registry covering a 2-year study period 1 January 2005 to 31 December 2006 were collected. Unexpected outcomes were defined as either/or hospital stay for >1 day (i.e. 2 nights at hospital or more), readmission within 30 days, reoperations within 12 months after repair including repair for recurrence, and death within 30 days after repair.

Results

The study cohort comprised 2,476 patients, and unexpected outcome was found in 267 patients/repairs (10.8 %). Prolonged hospital stay was by far the most prevalent indicator of unexpected outcome. Prolonged hospital stay was in 8.2 %, readmission in 2.1 %, reoperation in 0.7 %, and complications were observed in 1.1 %. One patient died within 30 days after repair, but death was not associated with the inguinal hernia repair. The usual technique was a simple sutured plasty (96.5 %). Emergency repair was performed in 54 patients (2.2 %) mainly in children between 0 and 2 years (79.6 %). During the 1 year follow-up, reoperation for recurrent inguinal hernia was performed in 8 children after elective repair (recurrence rate 0.3 %). Paediatric repairs were for most parts performed in surgical public hospitals, and most departments performed less than 10 inguinal hernia repairs within the 2 years study period.

Conclusion

These nationwide results are acceptable with low numbers of patients staying more than one night at hospital, low morbidity, and no procedure-related mortality.     

Spigelian hernia repair as a day-case procedure

Purpose

Only a few series of patients with a spigelian hernia managed on an outpatient basis have been reported in the literature. The aim of this prospective study was to evaluate the results of the elective spigelian hernia repair as an ambulatory procedure.

Methods

From June 2007 to June 2010, 8 patients with 9 spigelian hernias were electively operated on under local anesthesia as a day case. Four patients had unilateral spigelian hernia, 1 had spigelian and inguinal on the same side, 1 had spigelian and epigastric, 1 had spigelian and umbilical, and 1 patient had bilateral spigelian and umbilical hernia. Spigelian hernia was managed by the “open preperitoneal flat mesh technique.” In patients with several ventral hernias at different sites, “the open preperitoneal flat mesh technique” was performed using one separate flat mesh for each of the hernias; for the patient with inguinal hernia, the Lichtenstein procedure was performed in addition.

Results

No complications and recurrences were recorded during a mean follow-up of 23.5 months (range: 11–35).

Conclusion

The elective spigelian hernia can be successfully repaired under local anesthesia as a day-case procedure. The “open preperitoneal flat mesh technique” provides excellent results under these conditions.     

Repair of small and medium size ventral hernias with a Proceed Ventral Patch: a single center retrospective analysis

Purpose

Ventral hernias are common surgical targets. The Bard^® Ventralex? Hernia Patch was introduced for the repair of such hernias in the early 2000s. Ethicon (Johnson & Johnson) introduced the Proceed? Ventral Patch (PVP?) in the late 2000s for the same indication. The effectiveness and safety of the Bard^® Ventralex? Hernia Patch has been proven in a series of studies. There are no medical studies on the PVP? in humans. This study examines the effectiveness and safety of PVP? in the closure of ventral hernias.

Method

A single center retrospective analysis of patients’ data was conducted. Fifty-seven patients with small and medium size ventral hernias were treated with patches in the period between May 2009 and December 2010. The charts of these patients were reviewed. Demographic data, diagnosis at surgery, duration of surgery, length of hospital stay, postoperative complications and recurrence were recorded.

Results

Fifty-seven patients were analyzed including 21 females and 36 males with a mean age of 56.7 years. The diagnosis at surgery included 36 cases of umbilical hernia, eight cases of epigastric hernia, seven incision hernias and six recurrent umbilical hernias. The mean duration of surgery was 30.7 min, and the mean length of hospital stay was 3.3 days. Four postoperative complications (7.1 %) and one case of hernia recurrence (1.7 %) were recorded.

Conclusion

Ventral hernia closure with PVP? is safe and effective. The rates of complication and recurrence are comparable to those of the Bard^® Ventralex? Hernia Patch.     

Internal plug mesh without fixation in laparoscopic total extraperitoneal (TEP) repair of inguinal hernias: a pilot study

Purpose

Mesh fixation is essential in laparoscopic total extraperitoneal (TEP) repair of inguinal hernia; however, fixation sometimes causes post-operative pain. This study investigated a novel method of laparoscopic TEP repair without mesh fixation.

Methods

This study reviewed data from about two-hundred and forty-one laparoscopic TEP repairs on 219 patients, which were performed between December 2004 and October 2005.

Results

There were no statistically significant differences in the recurrence rate, seroma formation, and hospital stay. However, the mean operation time was shorter in the internal plug mesh group than the fixation group (p = 0.009), and post-operative pain only occurred in 4 cases in the internal plug mesh group in comparison to 29 cases in the mesh fixation group (p = 0.014).

Conclusions

An internal plug mesh without fixation might reduce post-operative pain after laparoscopic TEP repair of an inguinal hernia. Internal plug mesh without fixation may be an alternative method in laparoscopic TEP repair, especially for those involving indirect hernias.
