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.     

Lower Reoperation Rate for Recurrence after Mesh versus Sutured Elective Repair in Small Umbilical and Epigastric Hernias. A Nationwide Register Study

Background

Repair for a small (≤2 cm) umbilical and epigastric hernia is a minor surgical procedure. The most common surgical repair techniques are a sutured repair or a repair with mesh reinforcement. However, the optimal repair technique with regard to risk of reoperation for recurrence is not well documented. The aim of the present study was in a nationwide setup to investigate the reoperation rate for recurrence after small open umbilical and epigastric hernia repairs using either sutured or mesh repair.

Materials and methods

This was a prospective cohort study based on intraoperative registrations from the Danish Ventral Hernia Database (DVHD) of patients undergoing elective open mesh and sutured repair for small (≤2 cm) umbilical and epigastric hernias. Patients were included during a 4-year study period. A complete follow-up was obtained by combining intraoperative data from the DVHD with data from the Danish National Patient Register. The cumulative reoperation rates were obtained using cumulative incidence plot and compared with the log rank test.

Results and conclusions

In total, 4,786 small (≤2 cm) elective open umbilical and epigastric hernia repairs were included. Age was median 48 years (range 18–95 years). Follow-up was 21 months (range 0–47 months). The cumulated reoperation rates for recurrence were 2.2 % for mesh reinforcement and 5.6 % for sutured repair (P = 0.001). The overall cumulated reoperation rate for sutured and mesh repairs was 4.8 %. In conclusion, reoperation rate for recurrence for small umbilical and epigastric hernias was significantly lower after mesh repair compared with sutured repair. Mesh reinforcement should be routine in even small umbilical or epigastric hernias to lower the risk of reoperation for recurrence avoid recurrence.     

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.     

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.

     

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.     

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.     

Low recurrence rate and low chronic pain associated with inguinal hernia repair by laparoscopic placement of Parietex ProGrip™ mesh: clinical outcomes of 220 hernias with mean follow-up at 23 months

Introduction

The aim of this study was to demonstrate the safety and the efficacy of the self-gripping Parietex ProGrip? mesh (Sofradim Production, Trévoux, France) used with the laparoscopic approach for inguinal hernia repair. The incidence of chronic pain, post-operative complications, patient satisfaction and hernia recurrence at follow-up after 12 months was evaluated.

Methods

Data were collected retrospectively from patient files and were analyzed for 169 male and female patients with 220 primary inguinal hernias. All patients included had undergone surgical repair for inguinal hernia by the laparoscopic transabdominal preperitoneal approach using Parietex ProGrip? meshes performed in the same clinical center in Germany. Pre-, per- and post-operative data were collected, and a follow-up after 12 months was performed prospectively. Complications, pain scored on a 0–10 numeric rating scale (NRS), patient satisfaction and hernia recurrence were assessed.

Results

The only complications were minor and were post-operative: hematoma/seroma (3 cases), secondary hemorrhage through the trocar’s site (2 cases), hematuria, emphysema in the inguinal regions (both sides) and swelling above the genital organs (1 case for each). At mean follow-up at 22.8 months, there were only 3 reports of hernia recurrence: 1.4 % of the hernias. Most patients (95.9 %) were satisfied or very satisfied with their hernia repair with only 1.2 % reporting severe pain (NRS score 7–10) and 3.6 % reported mild pain.

Conclusion

This study demonstrates that in experienced hands, inguinal hernia repair surgery performed by laparoscopic transabdominal preperitoneal hernioplasty using Parietex ProGrip? self-gripping meshes is rapid, efficient and safe with low pain and low hernia recurrence rate.     

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.     

Open preperitoneal mesh repair of inguinal hernias using a mesh with nitinol memory frame

Purpose

To prospectively evaluate the use of a continuous Nitinol containing memory frame patch during a TIPP-technique in the open repair of inguinal and femoral hernias.

Methods

Over a 3-year period all consecutive adult patients that needed treatment for an inguinal or femoral hernia were treated by the TIPP repair using the Rebound Shield mesh. Intra-operatively the type and size of the hernia were evaluated according to the EHS classification, as well as the size of the mesh used. Baseline characteristics for all patients were evaluated considering age, gender, BMI and American society of Anesthesiologists score. Standard X-ray was performed to evaluate mesh position. All patients were evaluated for post-operative pain using the visual analogue scale (VAS 0–10 scale).

Results

In total 289 groin hernias were operated using a nitinol containing patch in 235 patients. The mean operating time was 38 min for unilateral hernias and 59 min for bilateral hernias. The median follow-up is 21.2 months (14–33 months) during which three patients died, unrelated to the groin hernia repair. At the time of re-evaluation 12 patients (5.0 %) complained of chronic pain, with a VAS score higher than 3 after 3 months (range 3–10). Two of these patients already had severe pain pre-operatively. A total of 3 recurrences (2.9 %) were noted with strong correlation with X-ray findings.

Conclusion

A nitinol memory frame containing mesh is a valuable tool to achieve complete deployment of a large pore mesh in a TIPP repair for inguinal hernias with acceptable morbidity and a low recurrence rate.     

Inguinal hernia repair in women: is the laparoscopic approach superior?

Purpose

Laparoscopic inguinal hernia repair is associated with reduced post-operative pain and earlier return to work in men. However, the role of laparoscopic hernia repair in women is not well reported. The aim of this study was to review the outcomes of the laparoscopic versus open repair of inguinal hernias in women and to discuss patients’ considerations when choosing the approach.

Methods

A retrospective chart review of all consecutive patients undergoing inguinal hernia repair from January 2005 to December 2009 at a single institution was conducted. Presentation characteristics and outcome measures including recurrence rates, post-operative pain and complications were compared in women undergoing laparoscopic versus open hernia repair.

Results

A total of 1,133 patients had an inguinal herniorrhaphy. Of these, 101 patients were female (9 %), with a total of 111 hernias. A laparoscopic approach was chosen in 44 % of patients. The majority of women (56 %) presented with groin pain as the primary symptom. Neither the mode of presentation nor the presenting symptoms significantly influenced the surgical approach. There were no statistically significant differences in hernia recurrence, post-operative neuralgia, seroma/hematoma formation or urinary retention between the two approaches (p < 0.05). A greater proportion of patients with bilateral hernias had a laparoscopic approach rather than an open technique (12 vs. 2 %, p = 0.042).

Conclusions

Laparoscopic herniorrhaphy is as safe and efficacious as open repair in women, and should be considered when the diagnosis is in question, for management of bilateral hernias or when concomitant abdominal pathology is being addressed.     

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.     

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.

     

The incidence and natural course of occult inguinal hernias during TAPP repair

Background

One of the proposed advantages of laparoscopic inguinal hernia repair is complimentary inspection of the contralateral side and possible detection of occult hernias. Incidence of occult contralateral hernias is as high as 50 %. The natural course of such occult defects is unknown and therefore operative rationale is lacking. This study was designed to analyze the incidence of occult contralateral inguinal hernias and its natural course.

Methods

A total of 1,681 patients were diagnosed preoperatively with unilateral inguinal hernia. None of these patients had complaints of the contralateral side preoperatively. All patients underwent laparoscopic inguinal hernia transabdominal preperitoneal (TAPP) repair. Operative details were analyzed retrospectively. Patients with occult contralateral defects were identified and tracked. Patients with an evident occult hernia received immediate repair. Patients with a smaller beginning or incipient hernia were followed.

Results

In 218 (13 %) patients, an occult hernia was found at the contralateral side during preoperative exploration. In 129 (8 %) patients, an occult true hernia was found. In 89 (5 %) patients, an occult incipient hernia was found. An incipient hernia was defined as a beginning hernia. All patients with an incipient hernia were followed. The mean follow-up was 112 (range 16–218) months. Twenty-eight (32 %) patients were lost to follow-up. In the 61 remaining patients, 13 (21 %) occult incipient hernias became symptomatic requiring repair. The mean time between primary repair and development of a symptomatic hernia on the contralateral side was 88 (range 24–210) months.

Conclusions

This study shows that the incidence of occult contralateral hernias is 13 % during TAPP repair of unilateral diagnosed inguinal hernias. In 5 % of the cases, the occult hernia consisted of a beginning hernia. Eventually, one of five will become symptomatic and require repair. These outcomes support immediate repair of occult defects, no matter its size.     

Repeated laparoscopic treatment of recurrent inguinal hernias after previous posterior repair

Background

The reported recurrence rates after laparoscopic inguinal hernia repair are 0–4 %. It is unclear which technique could best be offered to a patient with a recurrent hernia after a previous posterior repair. The purpose of this retrospective study was to determine the safety, feasibility, and reliability of a repeated laparoscopic repair (TAPP) for a recurrent hernia after a previous posterior inguinal hernia repair.

Methods

The study group contains 2,594 consecutive transabdominal inguinal hernia repairs (TAPP). Of these, 53 repairs were attempted in 51 patients for recurrent hernias after a previous posterior repair. During the follow-up period, patients were examined for recurrences and for presence of a port-site hernia. Pain was scored by the visual analogue pain scale (VAS).

Results

Fifty-one patients underwent a TAPP repair for a recurrent inguinal hernia after previous posterior hernia repair. Two patients presented a bilateral recurrent inguinal hernia. In two thirds of the patients, the recurrence was located caudally or medially from the previously placed mesh. Two attempted repairs had to be converted to an open technique due to severe adhesions. One intraoperative complication was encountered when the vas deferens was ligated during surgery due to adhesions of the previous placed mesh. Nine patients encountered an adverse event postoperatively, but none of them were serious events. No mesh infections were reported. The mean follow-up was 70 (range, 1–198) months. At follow-up, no recurrences were found at physical examination. Four patients developed a port-site hernia. Four patients had complaints of postoperative pain and were restricted in daily activities due to groin pain. The mean VAS score (scale 0–100), including the four patients with persistent pain, was 5.7 (range, 0–61).

Conclusions

It is concluded that repeated laparoscopic hernia repair (TAPP) is a definite repair for recurrent inguinal hernias. The procedure is feasible, safe, and reliable.     

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.     

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.     

Direct and Recurrent Inguinal Hernias Are Associated with Ventral Hernia Repair: A Database Study

Background

A systemically altered connective tissue metabolism has been demonstrated in patients with abdominal wall hernias. The most pronounced connective tissue changes are found in patients with direct or recurrent inguinal hernias as opposed to patients with indirect inguinal hernias. The aim of the present study was to assess whether direct or recurrent inguinal hernias are associated with an elevated rate of ventral hernia surgery.

Methods

In the nationwide Danish Hernia Database, a cohort of 92,457 patients operated on for inguinal hernias was recorded from January 1998 until June 2010. Eight-hundred forty-three (0.91 %) of these patients underwent a ventral hernia operation between January 2007 and June 2010. A multivariate logistic regression analysis was applied to assess an association between inguinal and ventral hernia repair.

Results

Direct (Odds Ratio [OR] = 1.28 [95 % CI, 1.08–1.51]) and recurrent (OR = 1.76, [95 % CI, 1.39–2.23]) inguinal hernias were significantly associated with ventral hernia repair after adjustment for age, gender, and surgical approach (open or laparoscopic).

Conclusions

Patients with direct and recurrent inguinal herniation are more prone to ventral hernia repair than patients with indirect inguinal herniation. This is the first study to show that herniogenesis is associated with type of inguinal hernia.     

Self-gripping mesh versus staple fixation in laparoscopic inguinal hernia repair: a prospective comparison

Background

Transabdominal preperitoneal (TAPP) repair is widely used to treat bilateral or recurrent inguinal hernias. Recently a self-gripping mesh has been introduced into clinical practice. This mesh does not need staple fixation and thus might reduce the incidence of chronic pain. This prospective study aimed to compare two groups of patients with bilateral (BIH) or monolateral (MIH) primary or recurrent inguinal hernia treated with TAPP using either a self-gripping polyester and polylactic acid mesh (SGM) or a polypropylene and poliglecaprone mesh fixed with four titanium staples [standard technique (ST)].

Methods

In this study, 96 patients (mean age, 58 years) with BIH (73 patients with primary and recurrent hernia) or MIH (22 patients with recurrent hernia) underwent a TAPP repair. For 49 patients, the repairs used SGM, and for 46 patients, ST was used. The patients were clinically evaluated 1 week and then 30 days postoperatively. After at least 6 months, a phone interview was conducted. The short-form McGill Pain Questionnaire was administered to all the patients at the 6-month follow-up visit.

Results

The mean length of the procedure was 83 min in the SGM group and 77.5 min in the ST group. The mean follow-up period was 13.8 months (range 1.3–42.0 months) for the SGM group and 18.2 months (range 1.9–27.1 months) for the ST group. The recurrence rate at the last follow-up visit was 0 % in the SGM group and 2.2 % (1 patient) in the ST group. The incidence of mild chronic pain at the 6-month follow-up visit was 4.1 % in the SGM group and 9.1 % in the ST group, and the incidence of moderate or severe pain was respectively 2.1 and 6.8 %.

Conclusions

The study population was not large enough to obtain statistically significant results. However, the use of SGM for TAPP repairs appeared to give good results in terms of chronic pain, and the incidence of recurrences was not higher than with ST. In our unit, SGM during TAPP repair of inguinal hernias has become the standard.     

Laparoscopic inguinal hernioplasty after radical prostatectomy: is it safe? Prospective clinical trial

Introduction

Despite inguinal hernia repair being one of the most common elective operations performed in general surgical practice, there are many controversies including indications for repair and selection of the surgical technique. In recent years, laparoscopic repair has gained wider acceptance because it is associated with fewer postoperative complications and less chronic pain when compared with conventional approaches with similar recurrence rate. However, patients with lower abdominal surgery are contraindicated for laparoscopic approach. There are few studies that evaluated whether patients who have been subjected to radical prostatectomy might be subjected to laparoscopic hernia repair with the same benefits as those without previous radical prostatectomy.

Methods

Between March 2010 and March 2013, 20 consecutive patients, who had been subjected to prior radical prostatectomy, underwent laparoscopic transabdominal inguinal repair and were followed prospectively. Surgical procedure was performed using a standard technique.

Results

Mean operative time was 67.5 min. There was only one (5 %) intraoperative minor complication, an injury to the inferior epigastric vessels, which was managed by clipping of the vessels. There were no major postoperative complications. After 24 h and on the seventh postoperative day, 85 and 90 % of patients had no pain or only complained of discomfort, respectively. Nine patients (45 %) did not need any analgesics postoperatively. The mean time to return to leisure activities and to work was 3.1 and 5.6 days, respectively. There was no conversion to open surgery. All patients were discharged within 24 h. After a mean follow-up of 14 months, none of the patients presented recurrence.

Conclusion

TAPP after prostatectomy is safe and effective. It seems that patients undergoing laparoscopic repair after radical prostatic resection have the same benefits as those without prostatectomy.     

Short- and mid-term outcome after laparoscopic repair of large incisional hernia

Purpose

To compare the outcome after laparoscopic incisional and ventral herniorrhaphy (LIVH) for fascial defect larger or equal than 15 cm in width with the outcome after LIVH in patients with hernia defect smaller than 15 cm.

Methods

From 2003 through 2010, 350 patients were submitted to LIVH. In 70 cases, hernia defect was ≥15 cm in width and in 280 was <15 cm. Incisional hernias were often recurrent, double or multiorificial. In the group of larger hernias, the rate of obesity, recurrent hernia and multiorificial hernia was 27.1, 24.2 and 12.8 %, respectively, and in the group of smaller hernias 27.3, 16.1 and 2.8 %, respectively. Patients were interviewed using McGill pain score test to measure postoperative quality of life (QoL) in the mid-term.

Results

LIVH for hernia ≥15 cm required longer surgical time (p = 0.034) and postoperative hospital stay (p = 0.0001). Besides, there were higher rate of postoperative prolonged ileus (p = 0.035) and polmonitis (p = 0.001). Overall recurrence rate was 2.6, 8.6 % for larger and 1.1 % for smaller incisional hernias, p = 0.045. Mc Gill pain test revealed no significant difference in the two groups of patients in postoperative QoL within 36 months.

Conclusions

Laparoscopic approach seems safe and effective even to repair large incisional hernia, the rate of recurrence was higher, but acceptable, if compared to smaller hernias. To the best of our knowledge, this is the largest reported series of incisional hernias ≥15 cm managed by laparoscopy.
