Purpose
The optimal technique and mesh type for parastomal hernia repair have yet to be ascertained. Biologic meshes have been advocated in parastomal hernia repair due to purported resistance to infection in contaminated fields. The aim of this study was to evaluate the effectiveness of additionally cross-linked acellular porcine dermal collagen mesh (Permacol?) for onlay parastomal hernia repair.Methods
A retrospective review of case notes, and abdominal CT scans when available, was performed for consecutive patients who had a parastomal hernia repaired between January 2007 and May 2010. All hernias were repaired with onlay placement of the biologic mesh. Hernias were classified according to the Moreno-Matias classification where CT scans were available.Results
Over a 34-month period, 30 consecutive patients, median age 74 years, 17 female, underwent parastomal hernia repair using onlay biologic mesh. There were 23 paracolostomy and seven paraileostomy hernias. The hernia was primary in 26 patients. Pre-operative CT scans were available in 18 patients (Moreno-Matias Type 1 = 1, Type 2 = 4, Type 3 = 13). There was one perioperative death, and 29 patients were available for follow-up, and median duration of follow-up (either CT or clinical) was 36 months (range 3–79). Twenty-six patients developed recurrence of the parastomal hernia (89.6 %), and median time to recurrence was 10 months (range 3–72),with Moreno-Matias Type 1 = 0, Type 2 = 4, Type 3 = 14, unknown = 8. Fifteen out of 26 patients have had repairs of the recurrence using a variety of techniques. Of these, 10 patients have had further recurrence.Conclusion
Onlay repair of parastomal hernia with cross-linked porcine dermal collagen biologic mesh reinforcement has poor long-term outcomes with unacceptably high recurrence rates and should not be performed.2.
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.3.

Purpose
The operative management of complex ventral hernia poses a formidable challenge, despite recent advances in surgical techniques. Recurrence rates after complex ventral hernia repair remain high, and increase with each failed attempt. This study examines the effect of pre-operative abdominal wall chemical component relaxation using Botulinum Toxin A (BTA) to induce temporary flaccid paralysis in order to facilitate laparoscopic repair of large complex ventral hernia.Methods
This is a prospective evaluation of 27 patients from January 2013 to August 2015 who underwent ultrasound guided BTA injections to the lateral abdominal wall muscles prior to elective complex ventral hernia repair. Non-contrast serial CT imaging was obtained pre- and post-BTA injection to measure change in fascial defect size and abdominal wall muscle thickness and length. Fascial defects were closed and hernias repaired using laparoscopic or laparoscopic-assisted intra-peritoneal onlay mesh (IPOM) techniques.Results
27 patients received pre-operative BTA injections which were well tolerated with no complications. Comparison of pre-BTA and post-BTA CT imaging demonstrated a significant increase in mean length of the lateral abdominal wall from 15.7 cm pre-BTA to 19.9 cm post-BTA (p < 0.0001), with mean unstretched length gain of 4.2 cm/side (range 0–11.7 cm/side). All hernias were surgically reduced and repaired with mesh, with no early recurrences.Conclusion
Pre-operative administration of BTA is a safe and effective technique in the pre-operative preparation of patients undergoing elective complex ventral hernia repair. This technique lengthens and relaxes the laterally retracted abdominal muscles and enables laparoscopic closure of large complex ventral hernia.4.
Background
Incisional hernias still are a major concern after laparotomy and are causing substantial morbidity. This study examines the feasibility, safety and incisional hernia rate of the use of a prophylactic intraperitoneal onlay mesh stripe (IPOM) to prevent incisional hernia following midline laparotomy.Methods
This prospective, randomized controlled trial randomly allocated patients undergoing median laparotomy either to mass closure of the abdominal wall with a PDS-loop running suture reinforced by an intraperitoneal composite mesh stripe (Group A) or to the same procedure without the additional mesh stripe (Group B). Primary endpoint was the incidence of incisional hernias at 2 years following midline laparotomy. Secondary endpoints are were the feasibility, the safety of the mesh stripe implantation including postoperative pain, and the incidence of incisional hernias at 5 years.Results
A total of 267 patients were included in this study. Follow-up data 2 years after surgery was available from 210 patients (Group A = 107; Group B = 103). An incisional hernia was diagnosed in 18/107 (17%) patients in Group A and in 40/103 (39%) patients in Group B (p < 0.001). A surgical operation due to an incisional hernia was conducted for 12/107 (11%) patients in Group A and for 24/103 (23%) patients in Group B (p = 0.039). In both groups, minor and major complications as well as postoperative pain are reported with no statistically significant difference between the groups, even in contaminated situations.Conclusions
This first randomized clinical trial indicates that the placement of a non-absorbable IPOM-stripe with prophylactic intention may significantly reduce the risk for a midline incisional hernia.Trial registration

Background
Ventral hernia is common, complicating up to 20 % of laparotomies. Plication of the rectus sheath with lateral component separation (LCS) provides a durable repair with acceptable functional outcomes. Additional support to the anterior abdominal wall may be provided by synthetic or biological mesh. Biological grafts invoke local tissue remodeling and result in strong fibrocollagenous tissue able to support the dynamic stressor of the anterior abdominal wall. Biodesign graft is a new graft derived from porcine small-intestine submucosa. We aim to review the use of Biodesign mesh for repair of ventral hernia with LCS.Methods
Patients underwent ventral hernia repair completed with plication of the rectus sheath, LCS, and use of an onlay Biodesign graft. Data was collected retrospectively. Key outcome measures included post-operative complications and recurrence.Results
Twelve patients were included for analysis. Mean age was 51.2 years, with 50 % males and a median weight of 87 kg (65–111 kg). Median operative time was 210 min (147 to 278 min) and median length of stay was 4 days. At a mean follow-up of 14.0 months, 8/12 (66 %) developed seroma, 1/12 (8 %) developed abdominal wall abscess, and 1/12 (8 %) suffered flap failure requiring vacuum dressings for closure. No patients were complicated by ventral hernia recurrence.Conclusions
Our results describe an early Australian experience of onlay Biodesign graft in the context of rectus sheath plication with LCS. We report acceptable rates of post-operative complications and recurrence.Level of evidence: IV, therapeutic study.6.
Background
We introduced single-incision transabdominal preperitoneal (S-TAPP) herniorrhaphy (described herein) at our institution in June 2010. We recently conducted a retrospective study to assess the feasibility and safety of the procedure.Methods
The study involved 182 patients (159 men, 23 women) who underwent S-TAPP herniorrhaphy between June 2010 and February 2015 for 202 groin hernias (162 unilateral hernias, 20 bilateral hernias). We examined patient characteristics, hernia type and presentation, operation time, conversion to another repair procedure, intraoperative blood loss, postoperative pain, morbidities, and postoperative hospital stay. We further evaluated operation time and morbidity by comparison between cases of simple unilateral hernia and cases of complicated unilateral hernia, which was defined as (1) a recurrent hernia, (2) hernia following radical prostatectomy, or (3) an incarcerated omental or bowel hernia.Results
Five types of hernia were treated: indirect inguinal, direct inguinal, femoral, combined inguinal, and other (a urinary bladder hernia). Operation time was 92.5 ± 29.1 min for the unilateral hernias and 135.7 ± 24.5 min for the bilateral hernias. No major bleeding occurred. Postoperative pain was short-lived and easily managed. Overall morbidity was 8.2% (15/182 patients), and only one postoperative complication (recurrence) required surgical intervention (repeat S-TAPP). Average postoperative stay was 6.7 ± 2.6 days. Two patients experienced numbness in the outer thigh, but this resolved naturally. One superficial surgical site infection developed and was easily treated. Operation times were greater for the complicated vs. simple hernias, but the time differed significantly (p = 0.02) only between radical prostatectomy-associated hernia and simple hernia. No complicated hernia required conversion to traditional laparoscopic repair, but in simple unilateral hernia group one conversion to traditional laparoscopic repair was required for difficulties encountered in the dissection of the large indirect inguinal hernia sac. The incidence of seroma was higher, though not statistically, in the complicated (n = 3) vs. simple hernia group.Conclusions
S-TAPP repair of groin hernia was shown to be a feasible, safe procedure. The advantages are well understood, and further studies are warranted to confirm the long-term benefits suggested by our study.7.
Background
Little is known about the clinical or patient-reported outcomes with non-operative management of ventral hernias. The aim of this prospective study is to determine the clinical and patient-reported outcomes of patients undergoing initial non-operative treatment of their ventral hernia.Study design
This was a prospective observational study of patients undergoing non-operative management of ventral hernias. Primary outcome was rate of surgical repair of the ventral hernias. Secondary outcomes included rate of emergency repair, elective repair, and emergency room visits. In addition, validated measurement tools for patient satisfaction and cosmetic satisfaction with their abdomen, abdominal pain, and patient function (modified Activities Assessment Scale, AAS) were utilized.Results
Of 128 patients who underwent non-operative management of a ventral hernia, 99(77.3%) patients were followed for a median (interquartile range) of 12.2(10.4–13.5) months. Twenty (20.2%) patients had at least 1 emergency room visit associated with their hernia. One-quarter (n = 2323.2%) underwent ventral hernia repair following enrollment. Twenty (20.2%) underwent elective repair, and 3 (3.0%) underwent emergent repair. Based on the modified AAS survey, patients who were managed non-operatively experienced no change in patient centered outcomes, while patients converted to operative management had improved scores.Conclusions and relevance
While the short-term risk of emergency surgery with non-operative management of ventral hernias is moderate, the chance of an emergency room visit and surgery is high. Patients who undergo non-operative management of their ventral hernias have no change in patient-reported outcomes at one year, while those converted to operative management experience improvement.8.
Purpose
Total extraperitoneal preperitoneal (TEP) repair is widely used for inguinal, femoral, or obturator hernia treatment. However, mesh repair is not often used for strangulated hernia treatment if intestinal resection is required because of the risk of postoperative mesh infection. Complete mesh repair is required for hernia treatment to prevent postoperative recurrence, particularly in patients with femoral or obturator hernia.Cases
We treated four patients with inguinocrural and obturator hernias (a 72-year-old male with a right indirect inguinal hernia; an 83-year-old female with a right obturator hernia; and 86- and 82-year-old females with femoral hernias) via a two-stage laparoscopic surgery. All patients were diagnosed with intestinal obstruction due to strangulated hernia. First, the incarcerated small intestine was released and then laparoscopically resected. Further, 8–24 days after the first surgery, bilateral TEP repairs were performed in all patients; the postoperative course was uneventful in all patients, and they were discharged 5–10 days after TEP repair. At present, no hernia recurrence has been reported in any patient.Conclusion
The two-stage laparoscopic treatment is safe for treatment of strangulated inguinal, femoral, and obturator hernias, and complete mesh repair via the TEP method can be performed in elderly patients to minimize the occurrence of mesh infection.9.

Background
The use of synthetic mesh for ventral hernia repair under contaminated conditions is a controversial issue due to the considerable risk of surgical site infection (SSI). This study aimed to review the outcomes of repair of incarcerated and strangulated ventral hernias with or without synthetic mesh in compliance with established clinical guidelines regarding the incidence of SSI and hernia recurrence.Methods
The records of patients with complicated ventral hernias who were treated with or without synthetic mesh repair were reviewed. Variables collected included the characteristics of patients and of ventral hernias, type of repair, and incidence of SSI and recurrence.Results
One hundred twenty-two patients (56 males) of a mean age of 56 years were included. Fifty-two (42.6%) and 70 (57.4%) patients presented with incarcerated and strangulated ventral hernias, respectively. Sixty-six (54%) patients were treated with on-lay mesh repair, and 56 (46%) were managed with suture repair. Twenty-one patients required bowel resection. SSI was detected in eight (6.5%) patients. There was no significant difference between both groups regarding the incidence of SSI (7.5% for mesh group vs 5.3% for suture group). Recurrence occurred in seven patients. Median follow-up period was 24 months. The suture repair group had a significantly higher incidence of recurrence than the mesh group. Diabetes mellitus, previous recurrence, and intestinal resection were significant predictors for SSI.Conclusion
Following established guidelines, synthetic mesh repair of incarcerated and strangulated ventral hernias attained lower recurrence rate, comparable incidence of SSI, and higher rate of seroma formation than suture repair.Trial registration

Purpose
Lightweight meshes (LWM) have shown benefits compared to heavyweight meshes (HWM) in terms of less postoperative pain and stiffness in open inguinal hernia repair. It appears to have similar advantages also in TEP, but concerns exist if it may be associated with higher recurrence rates. The aim of the study was to compare reoperation rate for recurrence of LWM to HWM in laparoscopic totally extra-peritoneal (TEP) repair.Methods
All groin hernias operated on with TEP between 1 January 2005 and 31 December 2013 at surgical units participating in The Swedish Hernia Register were eligible. Data included clinically important hernia variables. Primary endpoint was reoperation for recurrence. Median follow-up time was 6.1 years (0–11.5) with minimum 2.5 years postoperatively.Results
In total, 13,839 repairs were included for statistical analysis and 491 were re-operated for recurrence. Multivariate analysis demonstrated significantly increased risk of reoperation for recurrence in LWM 4.0% (HR 1.56, P?<?0.001) compared to HWM 3.2%. This was most evident in direct hernias (HR 1.75, P?<?0.001) and in hernia repairs with a defect >?3 cm (HR 1.54, P?<?0.021). The risk of recurrence with use of LWM in indirect hernias and in hernia repairs with a defect <?1.5 cm was more comparable to HWM.Conclusions
Lightweight meshes were associated with an increased risk of reoperation for recurrence compared to HWM. While direct hernias and larger hernia defects may benefit from HWM to avoid increased recurrence rates, LWM is recommended to be used in indirect and smaller hernia defects in TEP repair.11.
Purpose
To investigate which type of hernia that has the highest risk of a recurrence after a primary Lichtenstein repair.Methods
Male patients operated on with a Lichtenstein repair for a primary direct or indirect inguinal hernia and with a TEP for a later recurrence, with both operations recorded in the Swedish Hernia Register (SHR), were included in the study. The study period was 1994–2014.Results
Under the study period, 130,037 male patients with a primary indirect or direct inguinal hernia were operated on with a Lichtenstein repair. A second operation in the SHR was registered in 2236 of these patients (reoperation rate 1.7 %). TEP was the chosen operation in 737 in this latter cohort. The most likely location for a recurrence was the same as the primary location. If the recurrences change location from the primary place, we recognized that direct hernias had a RR of 1.51 to having a recurrent indirect hernia compared to having a direct recurrence after an indirect primary hernia repair.Conclusions
Recurrent hernias after Lichtenstein are more common on the same location as the primary one, compared to changing the location.12.

Background
An increasing number of patients have large or complex abdominal wall defects. Component separation technique (CST) is a very effective method for reconstructing complex midline abdominal wall defects in a manner that restores innervated muscle function without excessive tension. Our goal is to show our results by a modified CST for treating large ventral hernias.Materials and methods
A total of 351 patients with complex ventral hernias have been treated over a 10-year period. Pre- and postoperative CT scans were performed in all patients. All ventral hernias were W3, according to the EHS classification 1. We analyzed demographic variables, co-morbidities, hernia characteristics, operative, and postoperative variables.Results
One hundred and seventy patients (48.4%) were men; the average age of the study population was 51.6 ± 23.2 years with an average BMI of 32.3 ± 1.3. The hernia was located in the midline in 321 cases (91.5%) versus the flank in 30 (8.5%). In 45 patients, preoperative botulinum toxin (BT) and progressive pneumoperitoneum (PPP) were needed due to giant hernia defects when the VIH/VAC ratio was >20%. Postoperative complications related to the surgical site were seroma (35.1%), hematoma (9.1%), infection (7.2%), and wound necrosis (8.8%). Complications related to the repair were evisceration in 3 patients (1.1%), small bowel fistula in 4 patients (1.5%), 11 cases of mesh infection (2.9%), and abdominal compartment syndrome (ACS) in 2 patients. There were 29 hernia recurrences (8.2%) with a mean follow-up of 31.6 ± 8.1 months.Conclusion
The modified CST is an effective strategy for managing complex ventral hernias that enables primary fascial closure with low rates of morbidity and hernia recurrence.13.

Objective
The aim of this study was to evaluate hernia appearance at the trocar site after laparoscopic treatment of primary or incisional ventral hernias using an intraperitoneal prosthetic mesh. Chronic pain at the trocar site and primary hernia recurrence were also evaluated.Patients and methods
Two-hundred and twenty-six consecutive patients who underwent a standardized laparoscopic hernia repair for primary or incisional ventral hernia at our centre between January 2000 and December 2008 were included. All patients had clinical and radiological examinations. Primary end points were port site hernia and the occurrence of chronic trocar site pain. Secondary end point was primary hernia recurrence.Results
Seventy-eight patients were excluded: 6 declined to participate, 48 were unreachable, and 24 did not meet the inclusion criteria (nine underwent a single site laparoscopic approach, ten died of unrelated disease, three were unable to visit the hospital and two had relocated). After exclusion, 148 remained in our study. Mean follow-up was 49 ± 12.6 months. Mean age at the time of surgery was 60 years (range, 28–83) In total, 504 port sites were clinically and radiologically evaluated, and only one (0.02%) had secondary herniation. Three patients (2.0%) had a recurrent hernia, and 14 (9.5%) had developed chronic pain at time of assessment. Nine patients (6.1%) were re-operated for the recurrent hernia before the follow-up evaluation. The overall recurrence rate is, therefore, 8.1%. Only two minor complications and no major complications occurred after surgery. No mortality was observed.Conclusion
Laparoscopic repair for primary or incisional ventral hernias is a safe surgical approach, with low rates of hernia recurrence and a low morbidity rate. When fascial closure is maintained for 10 mm port sites, the incidence of port site hernias is very low. Five millimetre ports do not require closure.14.
Background
Seroma formation remains a common complication after an incisional hernia repair. The use of surgical drains is widespread, but evidence for their use and other adjuncts is limited. Our aim was to perform a systematic review of the literature on techniques used to reduce the incidence of post-operative seroma formation.Methods
A systematic search of PubMed and Embase databases was conducted using terms including “incisional hernia” and “seroma”. All studies on adults undergoing open incisional hernia repair with at least one intervention designed to reduce seroma formation were included.Results
Of the 1093 studies identified, 9 met the inclusion criteria. Medical talc: one cohort study of 74 patients undergoing talc application following pre-peritoneal mesh placement found a significantly decreased rate of seroma formation of 20.8 versus 2.7% (p < 0.001), but a retrospective study including 21 patients with onlay mesh found an increased rate of 76% seroma formation from 9.5% (p = 0.001). Fibrin glue: one comparative study including 60 patients found a reduction in seroma formation from 53 to 10% (p = 0.003), whereas a retrospective study of 250 patients found no difference (11 vs. 4.9% p = 0.07). Negative pressure wound therapy: four retrospective studies including a total of 358 patients found no difference in seroma outcome. Others: one randomised study of 42 patients undergoing either suction drainage or “quilting” sutures found no difference in seroma formation.Conclusions
There is currently insufficient quality evidence to recommend any of the investigated methods, some of which incur significant additional cost.15.
Purpose
To compare polypropylene mesh positioned onlay supported by omentum and/or peritoneum versus inlay implantation of polypropylene-based composite mesh in patients with complicated wide-defect ventral hernias.Methods
This was a prospective randomized study carried out on 60 patients presenting with complicated large ventral hernia in the period from January 2012 to January 2016 in the department of Gastrointestinal Surgery unit and Surgical Emergency of the Main Alexandria University Hospital, Egypt. Large hernia had an abdominal wall defect that could not be closed. Patients were divided into two groups of 30 patients according to the type of mesh used to deal with the large abdominal wall defect.Results
The study included 38 women (63.3 %) and 22 men (37.7 %); their mean age was 46.5 years (range, 25–70). Complicated incisional hernia was the commonest presentation (56.7 %).The operative and mesh fixation times were longer in the polypropylene group. Seven wound infections and two recurrences were encountered in the propylene group. Mean follow-up was 28.7 months (2–48 months).Conclusions
Composite mesh provided, in one session, satisfactory results in patients with complicated large ventral hernia. The procedure is safe and effective in lowering operative time with a trend of low wound complication and recurrence rates.16.
Purpose
To evaluate the feasibility, safety, and long-term outcomes of laparoscopic two-port totally extraperitoneal (TEP) inguinal hernia repair.Methods
A 10-year retrospective analysis from 2004 to 2013 of patients undergoing two-port TEP performed by a single surgeon at three surgical centers.Results
336 consecutive patients underwent two-port TEP repairing 478 hernias. 315 (93.8 %) patients were male and 21 (6.2 %) were female. Mean age ± SD was 47 ± 14 years and mean body mass index ± SD was 28.0 ± 4.7 kg/m2. Indications for surgery included primary repair 303 (90.2 %), recurrence from open repair 28 (8.3 %), and incarcerated inguinal hernia 5 (1.5 %). 194 (57.7 %) cases were unilateral and 142 (42.3 %) were bilateral. Operative time ± SD was 38.7 ± 14.9 min for unilateral repair and 43.4 ± 17.6 min for bilateral repair. Two-port TEP was successful in 316 (94.0 %). 20 (6.0 %) cases required the addition of a third port. 2 (0.6 %) cases were converted to open repair. Mean follow-up time ± SD was 5.4 ± 2.7 years. Postoperative complications included urinary retention 5 (1.5 %), seroma 7 (2.1 %), hematoma 1 (0.3 %), surgical site infection 4 (1.2 %), and chronic inguinal pain 3 (0.9 %). 11 (2.3 %) hernias recurred.Conclusion
Two-port TEP appears to be a feasible, safe, and effective method for laparoscopic inguinal hernia repair and should be considered a viable, less invasive alternative to conventional three-port techniques.17.

Introduction
The recommendation in the European Hernia Society Guidelines for the treatment of recurrent inguinal hernias is to modify the technique in relation to the previous technique, and use a new plane of dissection for mesh implantation. However, the registry data show that even following previous open suture and mesh repair to treat a primary inguinal hernia, open suture and mesh repair can be used once again for a recurrent hernia. It is therefore important to know what the outcome of open repair of recurrent inguinal hernias is compared with open repair of primary inguinal hernias, while taking the previous operation into account.Patients and methods
In the Herniamed Registry, a total of 17,594 patients with an open primary or recurrent unilateral inguinal hernia repair in men with a 1-year follow-up were prospectively documented between September 1, 2009 and August 31, 2013. Of these patients, 15,274 (86.8 %) had an open primary and 2320 (13.2 %) open recurrent repair. In the unadjusted and multivariable analyses, the dependent variables were intra- and postoperative complications, reoperations, recurrences, pain at rest, pain on exertion, and pain requiring treatment.Results
Open recurrent repair compared with the open primary operation is a significant influence factor for higher intraoperative (p = 0.01) and postoperative (p = 0.05) complication rates, recurrence rate (p < 0.001), and pain rates (p < 0.001). With regard to repair of recurrent inguinal hernia, previous open mesh repair was associated with the least favorable outcome, and with the highest odds ratio, for all outcome criteria. Open recurrent repair following previous endoscopic operation presented the least risk for postoperative complications, complication-related reoperations, and re-recurrences. The pain rates identified on follow-up after open recurrent repair were lower following previous open suture operation compared with following open and endoscopic mesh repair.Summary
A significantly less favorable perioperative and 1-year follow-up outcome must be expected for open repair of recurrent inguinal hernia in comparison with open primary inguinal hernia repair. After open recurrent repair, the most favorable perioperative complication and recurrence rates were identified following previous endoscopic repair, and the lowest pain rates following previous open suture repair. Open recurrent repair following previous open mesh operation was associated with the highest risks for perioperative complications, re-recurrences, and pain.18.
Background
Femoral hernias are an often unexpected groin pathology during childhood. However, the pediatric surgeon has to be aware to diagnose femoral hernia and to repair this condition. This is the first report on laparoscopic percutaneous extraperitoneal closure of femoral hernia (LPEF) in children and adolescents.Methods
Over a 6-year period in a bi-institutional clinical study, we retrospectively identified six children and one young adult who underwent LPEF repair.Results
Femoral hernia was laparoscopically confirmed in seven patients. Ages at surgery were 3, 5, 7, 7, 8, 8.5, and 18 years, respectively. In the first case, we combined laparoscopic diagnosis with open repair. In the consecutive six cases, hernias were repaired minimally invasively with the percutaneous extraperitoneal technique described below. During a follow-up between 6 years and 6 months, no recurrence was observed.Surgical technique
For LPEF, we percutaneously placed a peritoneal U-shape suture with integrated transfixation of the hernia sac, closed with an epifascial knot. We performed LPEF using two graspers. The peritoneum was percutaneously punctured with a venous cannula through which the suture was inserted. One grasper was inserted through the working channel of the laparoscope to invert the hernia sac into the abdominal cavity. A mini-grasping forceps inserted through the cannula retrieved the thread and completed LPEF.Conclusion
We demonstrate that single-port laparoscopic percutaneous extraperitoneal closure of femoral hernia is successful and quick in children and in adolescents.19.
Purpose
The purpose of this study is to describe our policy in selecting different types of anaesthesia and anterior tension-free techniques for the repair of recurrent inguinal hernias previously treated by anterior approach and to evaluate early and late outcomes.Methods
The medical records of 111 patients who underwent recurrent inguinal hernia repair by anterior approach in the period 2000–2013 were reviewed. Fifty patients (45 %) were over 70 years old and 63 (56.7 %) had one or more co-morbidities. Hernias with large defects were the most frequently observed (59.5 %), and no-mesh techniques were the most frequent failed repair (75.7 %). Different anterior tension-free techniques and types of anaesthesia were used, depending on hernia and patient characteristics. Seventy-three patients (65.8 %) were operated on an outpatient basis.Results
Mean follow-up period was 89 months (range 10–183). No perioperative deaths, medical events, or visceral injuries were recorded. Early postoperative complications occurred in 11 patients: 4 haematomas (3.6 %), 5 seromas (4.5 %), 1 superficial wound infection (0.9 %) and 1 ischemic orchitis (0.9 %). Late complications consisted in 3 cases of chronic moderate pain (3.2 %) and 2 re-recurrences (2.1 %).Conclusions
Recurrent inguinal hernia previously treated by open anterior technique can be repaired using the same approach, often on an outpatient basis, with a low rate of recurrence and postoperative complications. To be safe and effective, the repair should be performed by appropriately trained surgeons, well versed in the use of different types of anaesthesia and surgical techniques depending on patient and hernia characteristics.20.
