Introduction
The guidelines of the international hernia societies recommend laparo-endoscopic inguinal hernia repair for recurrent hernias after open primary repair. To date, no randomized trials have been conducted to compare the TEP vs TAPP outcome for recurrent inguinal hernia repair. A Swiss registry study identified only minor differences between the two techniques, thus suggesting the equivalence of the two procedures.Materials and Methods
Between September 1, 2009 and August 31, 2013 data were entered into the Herniamed Registry on a total of 2246 patients with recurrent inguinal hernia repair following previous open primary operation in either TAPP (n?=?1,464) or TEP technique (n?=?782).Results
Univariable and multivariable analysis did not find any significant difference between TEP and TAPP with regard to the intraoperative complications, complication-related reoperations, re-recurrences, pain at rest, pain on exertion, or chronic pain requiring treatment. The only difference identified was a significantly higher postoperative seroma rate after TAPP, which was influenced by the surgical technique, previous open primary operation and EHS-classification medial and responded to conservative treatment.Conclusion
TEP and TAPP are equivalent surgical techniques for recurrent inguinal hernia repair following previous open primary operation. The choice of technique should be tailored to the surgeon’s expertise.2.
Purpose
Chronic post-operative groin pain is a substantial complication following open mesh inguinal hernia repair. The exact cause of this pain is still unclear, but entrapment or trauma of the ilioinguinal nerve may have a role to play. Elective division of this nerve during hernia repair has been proposed in an attempt to reduce the incidence of chronic groin pain.Methods
We performed a meta-analysis of nine randomized controlled trials comparing preservation versus elective division of the ilioinguinal nerve during this operation.Results
A substantial proportion of patients having open mesh inguinal hernia repair experience chronic groin pain when the ilioinguinal nerve is preserved (estimated rate of 9.4% at 6 months and 4.8% at 1 year). Elective division of the nerve resulted in a significant reduction of groin pain at 6-months post-surgery (RR 0.47, p = 0.02), including moderate/severe pain (RR 0.57, p = 0.01). However, division of the nerve also resulted in an increase of subjective groin numbness at this time point (RR 1.55, p = 0.06). At 12-month post-surgery, the beneficial effect of nerve division on chronic pain was reduced, with no significant difference in the rates of overall groin pain (RR 0.69, p = 0.38), or of moderate-to-severe groin pain (RR 0.99, p = 0.98) between the two groups. The prevalence of groin numbness was also similar between the two groups at 12-month post-surgery (RR 0.79, p = 0.48).Conclusions
Routine elective division of the ilioinguinal nerve during open mesh inguinal hernia repair does not significantly reduce chronic groin pain beyond 6 months, and may result in increased rates of groin numbness, especially in the first 6-months post-surgery.3.

Background
Fixation of mesh is typically performed to minimize risk of recurrence in laparoscopic inguinal hernia repair. Mesh fixation with staples has been implicated as a cause of chronic inguinal pain. Our study aim is to compare mesh fixation using a fibrin sealant versus staple fixation in laparoscopic inguinal hernia and compare outcomes for hernia recurrence and chronic inguinal pain.Methods and procedures
PubMed was searched through December 2010 by use of specific search terms. Inclusion criteria were laparoscopic total extraperitoneal repair inguinal hernia repair, and comparison of both mesh fibrin glue fixation and mesh staple fixation. Primary outcomes were inguinal hernia recurrence and chronic inguinal pain. Secondary outcomes were operative time, seroma formation, hospital stay, and time to return to normal activity. Pooled odds ratios (OR) were calculated assuming random-effects models.Results
Four studies were included in the review. A total of 662 repairs were included, of which 394 were mesh fixed by staples or tacks, versus 268 with mesh fixed by fibrin glue. There was no difference in inguinal hernia recurrence with fixation of mesh by staples/tacks versus fibrin glue [OR 2.13; 95% confidence interval (CI) 0.60–7.63]. Chronic inguinal pain (at 3 months) incidence was significantly higher with staple/tack fixation (OR 3.25; 95% CI 1.62–6.49). There was no significant difference in operative time, seroma formation, hospital stay, or time to return to normal activities.Conclusions
The meta-analysis does not show an advantage of staple fixation of mesh over fibrin glue fixation in laparoscopic total extraperitoneal inguinal hernia repair. Because fibrin glue mesh fixation with laparoscopic inguinal hernia repair achieves similar hernia recurrence rates compared with staple/tack fixation, but decreased incidence of chronic inguinal pain, it may be the preferred technique.4.

Purpose
A large randomized, multicenter European study recently reported a reduction in early pain after open inguinal surgery when self-gripping mesh was used compared with sutured Lichtenstein repair. This secondary exploratory study is focused on the influence of nerve identification and handling on post-operative pain.Methods
Post-operative VAS pain data and Surgical Pain Scores (SPS) from 507 patients included in this study were analyzed according to whether inguinal nerves were preserved or resected during surgery to investigate whether identification and peri-operative nerve handling impact post-operative pain.Results
Preservation of the ilio-hypogastric nerve during Lichtenstein mesh repair with suture fixation was associated with significantly more post-operative pain compared with resection at each follow-up (p ≤ 0.003). This difference was not significant with self-gripping mesh repair. The decrease from baseline in post-operative VAS and SPS scores were significantly greater after self-gripping mesh repair compared to Lichtenstein repair at 1 year, but only when the ilio-hypogastric nerve was preserved (VAS scores, p = 0.009; SPS scores, p = 0.015). No such difference was observed with the ilio-inguinal nerve. When self-gripping mesh was used, preservation of the ilio-hypogastric nerve was associated with significantly greater decreases in post-operative pain (change in VAS score from baseline) compared with Lichtenstein repair at each follow-up (p ≤ 0.018).Conclusions
The ilio-hypogastric nerve is in danger of being traumatized during Lichtenstein mesh repair with suture fixation. The use of self-gripping mesh was shown to reduce the level of post-operative pain when the ilio-hypogastric nerve was preserved. Resection of the ilio-hypogastric nerve during Lichtenstein repair eliminates this difference.5.

Purpose
This study aimed to determine the outcome of perineal hernia repair with a biological mesh after abdominoperineal resection (APR).Method
All consecutive patients who underwent perineal hernia repair with a porcine acellular dermal mesh between 2010 and 2014 were included. Follow-up was performed by clinical examination and MRI.Results
Fifteen patients underwent perineal hernia repair after a median of 25 months from APR. Four patients had a concomitant contaminated perineal defect, for which a gluteal fasciocutaneous flap was added in three patients. Wound infection occurred in three patients. After a median follow-up of 17 months (IQR 12–24), a clinically recurrent perineal hernia developed in 7 patients (47 %): 6 of 11 patients after a non-cross-linked mesh and 1 of 4 patients after a cross-linked mesh (p = 0.57). Routine MRI at a median of 17 months revealed a recurrent perineal hernia in 7 of 10 evaluable patients, with clinical confirmation of recurrence in 5 of these 7 patients. No recurrent hernia was observed in the three patients with combined flap reconstruction for contaminated perineal defects.Conclusion
A high recurrence rate was observed after biological mesh repair of a perineal hernia following APR.6.
Purpose
To present a new and alternative method for surgical treatment of recurrent inguinal hernia after total extraperitoneal patch plastic (TEP).Methods
From January 2005 to September 2015, 35 patients (34 male, 1 female; mean age 65 ± 12.6 years) with recurrent inguinal hernia following TEP were operated at the Kliniken Essen-Mitte using a simplified method consisting of re-fixation of the primary mesh to the inguinal ligament by an anterior approach.Results
The mean operating time was 47 ± 22 min. All complications were minor with an overall incidence of 6%. After a mean follow-up of 54 months one re-recurrence was observed.Conclusions
This Simplified Hernia Repair is safe and avoids additional foreign body implantation. Therefore, it is our method of choice for recurrent inguinal hernias after TEP.7.
Background
Laparoscopic total extraperitoneal repair (TEP) of inguinal hernia has been associated with higher rates of recurrence compared to open methods. The aim of the present study was to determine independent risk factors for recurrence within 2 years after TEP.Methods
This was a single-centre prospective cohort study with consecutive inclusion of patients undergoing inguinal hernia repair from 2010 to 2014. Systematic follow-up was conducted 6 months and 2 years postoperatively. Risk factors for recurrence after 2 years were analysed in univariate and multivariate analyses.Results
A total of 1194 patients underwent TEP for inguinal or femoral hernia in the study period, of which 1047 were eligible for analyses. After 2 years, 56 (5.3%) patients had presented with recurrence. The following factors were associated with recurrence in univariate analyses: body mass index (BMI) >30 (HR 3.64; p = 0.011), medial vs. lateral hernia (HR 2.37; p = 0.004), repair of recurrent hernia vs. primary repair (HR 2.12; p = 0.049), and length of stay >1 day (HR 1.77; p = 0.043). In multivariate analyses, factors independently associated with recurrence after 2 years were BMI >30 (HR 3.74; p = 0.026) and medial vs. lateral hernia (HR 2.39; p = 0.004).Conclusion
The recurrence rate after TEP is higher than reported after open hernia repair. Attempts to decrease the rate should be persuaded. Good surgical technique with precise dissection and correct placement of the mesh, especially in medial hernias and obese patients, may be key points to improve outcomes after TEP.8.
Purpose
To evaluate the efficacy and safety of laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair in patients who have undergone robot-assisted laparoscopic radical prostatectomy (RALP).Methods
From July 2014 to December 2016, TAPP inguinal hernia repair was conducted in 40 consecutive patients who had previously undergone RALP. Their data were retrospectively analyzed as an uncontrolled case series.Results
The mean operation time in patients who had previously undergone RALP was 99.5 ± 38.0 min. The intraoperative blood loss volume was small, and the duration of hospitalization was 2.0 ± 0.5 days. No intraoperative complications or major postoperative complications occurred. During the average 11.2-month follow-up period, no patients who had previously undergone prostatectomy developed recurrence.Conclusions
Laparoscopic TAPP inguinal hernia repair after RALP was safe and effective. TAPP inguinal hernia repair may be a valuable alternative to open hernioplasty.9.

Background
Chronic pain after inguinal hernioplasty is the foremost side-effect up to 10–30% of patients. Mesh fixation may influence on the incidence of chronic pain after open anterior mesh repairs.Methods
Some 625 patients who underwent open anterior mesh repairs were randomized to receive one of the three meshes and fixations: cyanoacrylate glue with low-weight polypropylene mesh (n?=?216), non-absorbable sutures with partially absorbable mesh (n?=?207) or self-gripping polyesther mesh (n?=?202). Factors related to chronic pain (visual analogue scores; VAS?≥?30, range 0–100) at 1 year postoperatively were analyzed using logistic regression method. A second analysis using telephone interview and patient records was performed 2 years after the index surgery.Results
At index operation, all patient characteristics were similar in the three study groups. After 1 year, chronic inguinal pain was found in 52 patients and after 2 years in only 16 patients with no difference between the study groups. During 2 years’ follow-up, three (0.48%) patients with recurrences and five (0.8%) patients with chronic pain were re-operated. Multivariate regression analysis indicated that only new recurrent hernias and high pain scores at day 7 were predictive factors for longstanding groin pain (p?=?0.001). Type of mesh or fixation, gender, pre-operative VAS, age, body mass index or duration of operation did not predict chronic pain.Conclusion
Only the presence of recurrent hernia and early severe pain after index operation seemed to predict longstanding inguinal pain.10.
Background
Chronic groin pain appears in athletes with a diverse etiology. In a select few, it can be defined as a sportsman’s hernia, that may be related, among other pathologies, to weakness of the posterior inguinal wall and may successfully respond to surgery.Hypothesis
Surgical repair of the sportsman’s hernia is associated with good functional outcomes, if the diagnosis is based on meticulous examination and follows a simple selection flowchart.Study design
Prospective case cohort study.Methods
The study assessed patients recruited from 2006 until the present assessed by a dedicated team with clinical and radiographic features of a sportsman’s hernia who had failed a specified period of conservative therapies. Surgery was performed using a tension-free mesh open inguinal hernia repair.Results
Of 246 male patients with chronic groin pain, 51 underwent surgery (mean age 20.7 years, range 14–36 years) with 58 inguinal procedures performed. Of the operated group, seven underwent bilateral surgery with a direct hernia found in 9/58 operated sides (15.5 %), an indirect hernial sac in 8/58 (14 %) and a direct and indirect hernia being found in 3/58 (5 %) of operated sides. There was no post-operative morbidity (median follow-up 36.1 months; range 1–74 months), with two failures (3.45 % of operated sides). All other patients were asymptomatic, returned to full sports activity within 4.3 weeks (range 3–8 weeks) after surgery, and required no analgesics or further treatment.Conclusion
Selective surgical hernia repair, based on meticulous anamnesis and physical examination is effective in the management of chronic groin pain in athletes.11.

Background
Management of complications of laparoscopic inguinal hernia repair remains challenging as well as debatable. Relaparoscopy in management of these complications is relatively newer concept. We tried to analyse the feasibility of relaparoscopy (transabdominal preperitoneal approach) in management of complications of laparoscopic inguinal hernia repair.Materials and methods
The study group included 61 patients (referral cases) from a prospectively maintained database of previous laparoscopic inguinal hernia surgery with majority of the patients of recurrence (n = 39). Other complications were mesh infections (n = 15), pubic osteitis (n = 3), migration of mesh into adjacent viscera (n = 3) and meralgia paresthetica (n = 1). All patients underwent transabdominal preperitoneal approach (TAPP) between January 2007 and December 2013.Results and outcome
Most of the patients had previous TEP repair (n = 49) with variable complications detected in the range of 9 days to 38 months. Small-sized mesh (n = 12) and rolled up mesh (n = 10) were the causes of recurrence in 57 % cases. Mycobacterium tuberculosis (40 %) and mixed bacterial infections (33 %) strains were detected in the infected mesh. Pubic osteitis and meralgia paresthetica were tackers induced. All patients dealt with TAPP approach. Recurrent hernia cases underwent mesh placement and infected mesh was removed in mesh infection. Tackers were removed in cases of osteitis pubis and meralgia paraesthesia. Median operative time was 62 min (42–126 min) and hospital stay 3 days (2–13 days). The relaparoscopy was accomplished in 95.1 % of cases with no major intraoperative complications and minimal postoperative morbidity.Conclusion
Relaparoscopy through TAPP approach remains safe and feasible option to deal with primary laparoscopic hernia repair complications. Surgical techniques during primary laparoscopic repair are important cause for aforementioned complications. Though, surgical expertize remains warranted for relaparoscopy.12.
Background
Some patients with persistent inguinodynia following a Lichtenstein hernia repair fail all non-surgical treatments. Characteristics of mesh-related pain are not well described whereas a meshectomy is controversial. Aims were to define mesh-related pain symptoms, to investigate long-term effects of a meshectomy and to provide recommendations on meshectomy.Methods
Consecutive patients undergoing open meshectomy with/without selective neurectomy for chronic inguinodynia following Lichtenstein repair were analysed including a follow-up questionnaire. Outcome measures were complications, satisfaction (excellent, good, moderate, poor) and hernia recurrence rate. Recommendations for meshectomy are proposed based on a literature review.Results
Seventy-four patients (67 males, median age 56 years) underwent mesh removal (exclusively mesh, 26%; combined with tailored neurectomy, 74%) between June 2006 and March 2015 in a single centre. Complications were intraoperatively recognized small bowel injury (n = 1) and testicular atrophy (n = 2). A 64% excellent/good long-term result was attained (median 18 months). Success rates of a meshectomy (63%) or combined with a neurectomy (64%) were similar. Five hernia recurrences occurred during follow-up (7%). A patient with a pure mesh-related groin pain characteristically reports a ‘foreign body feeling’. Pain intensifies during hip flexion (car driving) and is attenuated following hip extension or supine position. Palpation is painful along the inguinal ligament whereas neuropathic characteristics (hyperpathic skin, trigger points) are lacking.Conclusions
Mesh removal either or not combined with tailored neurectomy is beneficial in two of three patients with characteristics of mesh-related inguinodynia following Lichtenstein hernia repair who are refractory to alternative pain treatments.13.

Background
Ventral hernia can be repaired through either an open or laparoscopic approach. A major problem following hernia repair is recurrence, and the technique used for hernia repair influences the rate of hernia recurrence. Data from individual studies show that the area of mesh overlap used during hernia repair correlates with hernia recurrence, but no meta-analyses have previously been published. The aim of this review was to perform a meta-analysis to determine if the area of mesh overlap correlates with the rate of hernia recurrence after ventral and incisional hernia repair.Methods
Studies from 1990 to 2013 that used a mesh in open or laparoscopic procedures, and that reported both the area of mesh overlap beyond the fascial defect and the recurrence rate, were assessed for inclusion in the final analysis. A pooled estimation of combined overall risk was calculated according to a random effect model.Results
A total of 95 articles, with 111 study populations, met all criteria and were included in the final analysis. For open procedures, results showed no correlation between the pooled estimation of risk for recurrence of ventral hernia and area of mesh overlap used for hernia repair (<3 cm, incidence rate 0.065; 3–5 cm, incidence rate 0.070; >5 cm, incidence rate 0.060). In laparoscopic procedures, the pooled estimation of risk for recurrence of hernia decreased with increasing area of mesh overlap (<3 cm, incidence rate 0.086; 3–5 cm, incidence rate 0.046; >5 cm, incidence rate 0.014).Conclusion
Risk of hernia recurrence decreases with increasing area of mesh overlap in laparoscopic, but not open, procedures for ventral hernia repair.14.
Background
Today, ventral hernia repair is predominantly performed with meshes. There is no meta-analysis of high quality evidence that compares the results of suture to mesh repair. The objective of this systematic review with meta-analysis is to compare patient centred outcomes of suture versus mesh repair.Methods
A systematic literature search was performed in EMBASE, MEDLINE and CENTRAL (inception to 06/2014). Furthermore a hand search was performed. RCTs comparing suture versus mesh repair in primary and incisional ventral hernia repair were included. Data on patient characteristics, interventions and results were extracted in standardized tables. Risk of bias was assessed with the cochrane risk of bias tool. Results of studies were pooled with a meta-analysis. All steps were performed by two reviewers. Discrepancies were discussed until a consensus.Results
The search in the databases resulted in 1560 hits. After screening, 10 randomized controlled trials including 1215 patients satisfied all inclusion criteria. Risk of bias was moderate to high. The relative risk for recurrence was 0.36 [95% CI (0.27, 0.49); I 2 = 0; heterogeneity p = 0.70]. Other complications did not differ significantly. Results for chronic pain were heterogeneous across studies.Conclusion
Mesh repair reduces the number of recurrences significantly. In patients without recurrence mesh repairs seem to be associated with a risk of chronic pain especially if the mesh is fixed sublay.15.
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.16.

Background
The advantage of single-port total extra-peritoneal (TEP) inguinal hernia repair over the conventional technique is still debatable. Our objective was to compare the outcomes of TEP inguinal hernia repair using either a single-port or conventional surgical technique, in two blind randomized groups of patients.Methods
In this prospective, randomized, double-blind, controlled clinical trial, 100 patients undergoing surgery for unilateral inguinal hernia were randomized into two groups: One group underwent conventional laparoscopic TEP inguinal hernia repair, while the other was selected for single-port TEP repair. Primary endpoint is postoperative pain (VAS), while secondary endpoints are recurrence, chronic pain and complications.Results
From 100 patients, 49 underwent single-port hernia TEP repair, 50 had conventional three-port TEP hernia repair, and one patient declined to participate after randomization. The two groups were comparable in terms of patient demographics and operative findings. Mean operative time was 49.1(±13.8) min in the conventional group and 54.1(±14.4) min in the single-port group (p = 0.08). Mean hospital stay was 19.7(±5.8) h in the conventional group and 20.5(±6.4) h in the single-port group (p = 0.489). No major complications and no recurrence reported at 11-month follow-up. No statistically significant difference noted in postoperative pain between the two groups at regular intervals.Conclusions
The outcomes after laparoscopic TEP inguinal hernia repair with a single-port device are similar but not superior to the conventional technique.17.

Purpose
Persistent pain is a known side effect after TEP inguinal repair disabling 2–5 % of patients. A standardized diagnostic work-up so far is not available. MRI is a diagnostic tool in the work-up of inguinal hernias. In the present study the yield of MRI in evaluating chronic pain after TEP hernia repair is addressed.Methods
In our database patients receiving an MRI scan for groin pain lasting more than 3 months after TEP inguinal hernia repair were identified. A checklist with potential pathologic findings was filled out for each groin by two blinded observers. Findings in painful, pain-free and unoperated groins were compared and statistical analysis done based upon their relative incidences. Cohen’s kappa coefficients were calculated to determine interobserver agreement.Results
Imaging studies of 53 patients revealed information regarding 106 groins. Fifty-five groins were painful after the initial operation, 12 were pain-free postoperatively and 39 groins were not operated. None of the predefined disorders was observed statistically more often in the patients with painful groins. Only fibrosis appeared more prevalent in patients with chronic pain (P = 0.11). Interobserver agreement was excellent for identifying the mesh (κ = 0.88) and observing bulging or a hernia (κ = 0.74) and was substantial for detecting fibrosis (κ = 0.63). In 40 % of the patients, MRI showed a correct mesh position and observed nothing else than minor fibrosis. A wait and see policy resolved complaints in the majority of the patients. In 15 % of the patients, MRI revealed treatable findings explanatory for persisting groin pain.Conclusion
For patients with post-TEP hernia groin pain, MRI is useful to confirm a correct flat mesh position and to identify possible not operation-related causes of groin pain. It is of little help to identify a specific cause of groin repair-related pain.18.

Purpose
There is a paucity of high-quality evidence concerning mesh choice in open inguinal hernia repair. Using an expertise-based randomized clinical trial design, we aimed to evaluate the postoperative impact of two different mesh types on pain and discomfort, quality of life and sex life.Methods
In two regional hospitals, male patients with primary inguinal hernia were randomized to one of two groups of surgeons that performed the Lichtenstein operation. One group of surgeons used a heavyweight polypropylene mesh (90 g/m2, Bard? Flatmesh, Davol) while the second group employed a lightweight mesh (28 g/m2, ULTRAPRO?, Ethicon). Follow-up data were collected by questionnaires and outpatient visits in the range of 1–3 years after surgery.Results
Some 412 patients were randomized and 363 patients were analysed. There was no difference in pain between groups after surgery but a statistically significant difference concerning awareness of a groin lump and groin discomfort, favouring the lightweight group 1 year after surgery. No differences in quality of life between groups could be detected but both groups had a substantially better quality of life postoperatively, as compared to before surgery. In the analysis of impact on sex life, no differences between mesh groups were found.Conclusion
The Lichtenstein operation performed for primary inguinal hernia improves quality of life for most of the male patients, independently of the type of mesh used. The lightweight mesh group experienced less awareness of a groin lump and groin discomfort 1 year postoperatively.ClinicalTrials.gov Identifier: NCT00451893.19.
Purpose
Different techniques and mesh materials are used in parastomal hernia repair with recently reported recurrence rates ranging from 10 to 28%. The aim of this cohort study was to examine the risk of recurrence and chronic pain after Sugarbaker or keyhole parastomal hernia repair with intraperitoneal placement of a polyester monofilament macroporous composite mesh.Methods
Data on all patients undergoing parastomal hernia repair with Parietex? Composite Parastomal Mesh at our institution during a 4-year period were examined. Patients with urostomy were excluded. A team of three experienced surgeons performed all repairs. Follow-up including physical examination was done after 10 days, 6 and 12 months, and hereafter as annual structured telephone interviews. Patients suspected of hernia recurrence were offered computed tomography scan. Chronic pain was defined as pain requiring out-patient visit(s) and/or regular use of analgesics.Results
79 patients (Sugarbaker, n = 69; keyhole, n = 10) were included. Of those, 72 procedures were performed laparoscopically and seven by open technique. Two patients were reoperated within 30 days with removal of the mesh. In total, seven (9%) patients had parastomal hernia recurrence (reoperation, n = 3; conservative management, n = 4) during follow-up of median 12 months (range 0–49 months). In univariable logistic analyses, type of stoma was associated with recurrence (ileostomy 28% vs colostomy 3%, p = 0.007). Three patients (4%) reported chronic pain.Conclusion
In this study, we found low rates of recurrence and chronic pain following parastomal hernia repair using intraperitoneal reinforcement with a polyester monofilament composite mesh.20.
