ABSTRACT
PURPOSE: The study objective is to document value created by real-world evidence from the Abdominal Core Health Quality Collaborative (ACHQC) for regulatory decisions. The ACHQC is a national effort that generates data on hernia repair techniques and devices. METHODS: Two retrospective cohort evaluations compared cost and time of ACHQC analyses to traditional postmarket studies. The first analysis was based on 25 reports submitted to the European Medicines Agency of 20 mesh products for post-market surveillance. A second analysis supported label expansion submitted to the Food and Drug Administration, Center for Devices and Radiological Health for a robotic-assisted surgery device to include ventral hernia repair. Estimated costs of counterfactual studies, defined as studies that might have been done if the registry had not been available, were derived from a model described in the literature. Return on investment, percentage of cost savings, and time savings were calculated. RESULTS: 45,010 patients contributed to the two analyses. The cost and time differences between individual 25 ACHQC analyses (41,112 patients) and traditional studies ranged from $1.3 to $2.2 million and from 3 to 4.8 years, both favoring use of the ACHQC. In the second label expansion analysis (3,898 patients), the estimated return on investment ranged from 11 to 461% with time savings of 5.1 years favoring use of the ACHQC. CONCLUSIONS: Compared to traditional postmarket studies, use of ACHQC data can result in cost and time savings when used for appropriate regulatory decisions in light of key assumptions.

AIM: Low anterior resection syndrome (LARS) is common after low anterior resection. Our aim was to evaluate the prevalence and 'bother' (subjective, symptom-associated distress) of major LARS after 1 and 2 years, identify possible risk factors and relate the bowel function to a reference population. METHOD: The QoLiRECT (Quality of Life in RECTal cancer) study is a Scandinavian prospective multicentre study including 1248 patients with rectal cancer, of whom 552 had an anterior resection. Patient questionnaires were distributed at diagnosis and after 1, 2 and 5 years. Data from the baseline and at 1- and 2-year follow-up were included in this study. RESULTS: The LARS score was calculated for 309 patients at 1 year and 334 patients at 2 years. Prevalence was assessed by a generalized linear mixed effects model. Major LARS was found in 63% at 1 year and 56% at 2 years. Bother was evident in 55% at 1 year, decreasing to 46% at 2 years. Major LARS was most common among younger women (69%). Among younger patients, only marginal improvement was seen over time (63-59%), for older patients there was more improvement (62-52%). In the reference population, the highest prevalence of major LARS-like symptoms was noted in older women (12%). Preoperative radiotherapy, defunctioning stoma and tumour height were found to be associated with major LARS. CONCLUSION: Major LARS is common and possibly persistent over time. Younger patients, especially women, are more affected, and perhaps these patients should be prioritized for early stoma closure to improve the chance of a more normal bowel function.

BACKGROUND: Identification of suboptimal mesh products is essential to improve the outcome after hernia surgery. This study investigated whether a national clinical database combined with administrative registries may serve as a tool for postmarketing evaluation of mesh products for hernia surgery. METHODS: This was a propensity score-matched case-control cohort study comparing outcomes in patients undergoing laparoscopic incisional hernia repair with either one particular mesh or any other synthetic mesh. Data on patients registered in the Danish Ventral Hernia Database between 2010 and 2016 were combined with administrative data from the Danish National Patient Registry. The primary outcome was operation for recurrence. Secondary outcomes were 30-day readmission, 30-day reoperation for complications (excluding hernia recurrence), and mortality after 30 and 90 days. RESULTS: In total, 740 patients who underwent repair with one particular mesh were matched with 1479 patients who received any other synthetic mesh. The rate of repair for hernia recurrence was significantly higher in the particular mesh group than in the reference group: 12·8 versus 6·3 per cent respectively (hazard ratio 2·09, 95 per cent c.i. 1·57 to 2·79; P < 0·001). Use of the particular mesh increased the risk of readmission (odds ratio (OR) 1·53, 1·16 to 2·01; P = 0·002) and reoperation for a complication (OR 1·60, 1·03 to 2·47, P = 0·030). No difference in mortality was found. CONCLUSION: Clinical registries with prospectively collected data can provide long-term surveillance of commercial mesh. Laparoscopic incisional hernia repair with one particular mesh was associated with an increased rate of short-term complications and double the risk of repair for recurrence.
ANTECEDENTES: Es esencial identificar los productos subóptimos referidos a las mallas para mejorar los resultados en la cirugía de la hernia. Este estudio analizó si un registro clínico nacional combinado con registros de bases de datos administrativos puede servir como herramienta para la evaluación post-comercialización de productos de mallas para cirugía de la hernia. MÉTODOS: Se efectuó un estudio de emparejamiento por puntaje de propensión de una cohorte de casos y controles en el que se comparaban los resultados de la malla Physiomesh® frente a cualquier otra malla sintética en pacientes sometidos a una reparación laparoscópica de una eventración. Se combinaron los datos de los pacientes del registro danés de hernia entre 2010 y 2016 con los datos administrativos del registro nacional de pacientes de Dinamarca. La variable principal fue la reintervención por recidiva. Las variables secundarias fueron el reingreso a 30 días, la reoperación a 30 días por complicaciones (excluyendo la recidiva de la hernia) y la mortalidad a 30 y 90 días. RESULTADOS: Para la reparación herniaria se utilizó la malla Physiomesh® en 740 pacientes, que se emparejaron mediante el análisis por puntaje de propensión con 1.479 pacientes en los que se colocó otra malla sintética. La reintervención por recidiva herniaria fue significativamente mayor en el grupo Physiomesh® (12,8%) que en el grupo de referencia (6,3%); cociente de riesgos instantáneos (hazard ratio, HR): 2,09 (i.c. del 95%: 1,57-2,79), P < 0,001. El riesgo de reingreso (razón de oportunidades, odds ratio, OR: 1,53, 1,16-2,01, P = 0,002)) y de reoperación por una complicación (OR: 1,60, 1,03-2,47, P = 0,030) fueron superiores en el grupo Physiomesh®. No hubo diferencia en la mortalidad. CONCLUSIÓN: Los grandes registros clínicos con datos recogidos de forma prospectiva pueden ser útiles para efectuar el seguimiento a largo plazo de una malla comercializada para garantizar la seguridad del producto y su calidad quirúrgica. La reparación laparoscópica de una eventración con la malla Physiomesh® se asociaba con un riesgo doble de recidiva y un aumento de la tasa de complicaciones a corto plazo.

PURPOSE: Patient-reported outcome measures (PROMs) have been increasingly accepted to evaluate the quality of surgery. The impact of a hernia on PROMs and the indication for elective ventral hernia mesh repair are poorly researched. The primary objective in this systematic review was to provide evidence for PROM changes at least 3 months after elective ventral hernia mesh repair. Secondarily, a critical appraisal of the study quality was undertaken. METHODS: Ovid MEDLINE, PubMed, Ovid Embase, and CENTRAL were searched (year 2000-May 12, 2019) for studies reporting any of 21 predefined PROMs pre- and ≥ 3 months postoperatively following adult ventral hernia mesh repair. A pre-study defined analysis method was used to assess pre- vs. postoperative PROM changes. Quality assessment was guided by criteria formulated by the National Institutes of Health. RESULTS: The search yielded 11,438 potentially eligible studies of which 24 met the inclusion criteria. Most studies were of poor or moderate quality and one study was of high quality. There was no evidence for a clinically relevant postoperative improvement in any PROM following umbilical hernia repair or medium-sized incisional hernia repair. A clinically relevant postoperative improvement of pain, physical impairment, and social involvement was seen in patients with a large-sized incisional hernia repair and stoma-related complaints in patients with a medium-sized parastomal hernia repair. CONCLUSION: This analysis suggested that a minor subset of PROMs improved in patients undergoing large-sized incisional and medium-sized parastomal hernia repair. High-quality studies are imperative in this extremely often conducted surgical procedure. TRIAL REGISTRATION: The review was registered at PROSPERO (CRD42018096671, https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=96671 ).

BACKGROUND: Safe laparoscopic cholecystectomy may necessitate biliary imaging, and non-invasive fluorescence cholangiography may have advantages over contrast X-ray cholangiography. This trial compared fluorescence and X-ray cholangiography for visualization of the critical junction between the cystic, common hepatic and common bile ducts. METHODS: This non-inferiority blinded RCT included patients who had either intraoperative fluorescence cholangiography using 0·05 mg/kg indocyanine green or X-ray cholangiography during elective laparoscopic cholecystectomy. RESULTS: Between March 2015 and August 2018, a total of 120 patients were randomized (60 in each group). There were no drop-outs and 30-day follow-up data were available for all patients. In intention-to-treat analysis, there was no difference between the fluorescence and X-ray cholangiography groups in ability to visualize the critical junction (49 of 60 versus 51 of 60 respectively; P = 0·230). Fluorescence cholangiography was faster by a few minutes: median 2·0 (range 0·5-5·0) versus 4·8 (1·3-17·6) min (P < 0·001). CONCLUSION: Fluorescence cholangiography was confirmed to be non-inferior to X-ray cholangiography in visualizing the critical junction during laparoscopic cholecystectomy. Registration number: NCT02344654 ( http://www.clinicaltrials.gov).
ANTECEDENTES: La práctica de una colecistectomía laparoscópica segura puede requerir imágenes de la vía biliar, en las cuales la colangiografía con fluorescencia no invasiva puede tener ventajas sobre la colangiografía con contraste con rayos X. Este ensayo comparó la colangiografía con fluorescencia con la colangiografía con rayos X para la visualización de la unión crítica entre el conducto cístico, el conducto hepático común y los conductos biliares comunes. MÉTODOS: Ensayo clínico aleatorizado, ciego, de no inferioridad que incluyó a 120 pacientes en los que durante la colecistectomía laparoscópica electiva se practicó una colangiografía con fluorescencia intraoperatoria utilizando 0,05 mg/kg de verde de indocianina o una colangiografía con rayos X. RESULTADOS: De marzo de 2015 a agosto de 2018, se aleatorizaron un total de 120 pacientes (6 en cada grupo), en los que no hubo abandonos y con datos de seguimiento de 30 días disponibles en todos ellos. Basado en un análisis por intención de tratamiento, la capacidad de visualizar la unión crítica fue igual entre los dos grupos (49/60 versus 51/60, P = 0,23). La colangiografía con fluorescencia fue más rápida de realizar, en unos pocos minutos (mediana 2 min (rango 0,5-5,0) versus 5 min (rango 5,2-17,6), P < 0,001). CONCLUSIÓN: Se confirmó que la colangiografía con fluorescencia no fue inferior a la colangiografía con rayos X para visualizar la unión crítica durante la colecistectomía laparoscópica.

BACKGROUND: Long-term clinical outcome after a recurrent inguinal hernia repair may be associated with the type of repair, that is, laparoscopic or open. The results from previous randomised controlled trials are inconclusive regarding the long-term risk of re-recurrence chronic pain. Accordingly, this trial compared laparoscopic transabdominal preperitoneal repair (TAPP) with Lichtenstein's repair. The primary outcome was repair for a re-recurrence. The secondary outcome was chronic pain. METHODS: Multi-centre single-blinded, randomised trial on TAPP vs Lichtenstein's repair in male patients operated for a recurrent inguinal hernia after a primary open inguinal hernia repair. Follow-up for repair for a re-recurrence was registered in the Danish Hernia Database. Prospective follow-up data were achieved by a structured questionnaire on pain-related functional impairment using the Activities Assessment Scale (AAS-pain). RESULT: A total of 360 patients were randomised, 297 were mailed the follow-up questionnaire (63 excluded) after median 12 years (range 9-15). A total of 265 patients responded to the questionnaire (response rate 89%). The cumulative rate of repair for re-recurrence after 12 years was 10% (95% confidence interval (CI) 5.3-15.1%) vs 10% (5.6-14.7%) after TAPP or Lichtenstein, respectively (p = 0.764). Moderate/severe AAS-pain was reported by 4% (95% CI 1-8%) vs 7% (95% CI 3-11%) patients after TAPP or Lichtenstein, respectively (p = 0.698) CONCLUSION: Long-term re-recurrence rate and incidence of chronic pain was surprisingly high respectless of surgical approach and neither TAPP nor Lichtenstein's procedure was superior to improve surgical results.

BACKGROUND: The objective of the study was to analyse patient-reported outcome measures (PROMs), seroma formation, long-term recurrence and chronic pain after closure of the fascial defect in patients undergoing laparoscopic umbilical hernia mesh repair. METHODS: This was a randomized double-blinded trial in patients undergoing elective laparoscopic umbilical hernia repair comparing sutured closure of the fascial defect before intraperitoneal onlay mesh (IPOM) repair with a no-closure IPOM repair. Postoperative pain, movement limitations, discomfort and fatigue were registered before surgery and on postoperative days 1-3, 7 and 30. Seroma formation, quality of life and cosmesis were assessed at day 30, and at 2 years of follow-up. Recurrence (clinical and reoperation) and chronic pain were assessed after 2 years. RESULTS: Eighty patients were randomized. Median defect sizes in closure and no-closure groups were 2·5 (range 1·5-4·0) and 2·5 (2·0-5·5) cm respectively (P = 0·895). There were no significant differences in early and late postoperative pain or in any other early or late PROMs, except for early fatigue which was higher in the closure group (P = 0·011). Seroma formation after 30 days was significantly reduced after closure (14 of 40; 35 (95 per cent c.i. 22 to 51) per cent) compared with no closure (22 of 38; 58 (42 to 72) per cent) (P = 0·043). Cumulative recurrence after 2 years was lower in the closure group: 5 of 36 (7 (3 to 17) per cent) versus 12 of 37 (19 (10 to 33) per cent) for no closure (P = 0·047). CONCLUSION: Closure of the fascial defect in laparoscopic umbilical hernia IPOM repair significantly reduced early seroma formation and long-term recurrence without inducing side-effects such as pain, or other early or late PROMs. Registration number: NCT01962480 ( https://www.clinicaltrials.gov).

BACKGROUND: Majority of studies on chronic postoperative inguinal pain has described the occurrence after unilateral inguinal hernia repair. Endo-laparoscopic repair, for example, laparoscopic transabdominal preperitoneal inguinal hernia repair, has been recommended for primary bilateral symptomatic inguinal hernias, although the literature on chronic postoperative inguinal pain among this type of patients is limited. The present study analyzed chronic postoperative inguinal pain following bilateral transabdominal preperitoneal inguinal hernia repair. METHODS: Nationwide consecutive patients who underwent bilateral transabdominal preperitoneal inguinal hernia repair (July 2012-June 2013) were recruited from the Danish Inguinal Hernia Database and cross-checked with hospital files and the National Patient Registry. A prospective follow-up was performed with a standardized postal questionnaire including questions on functional performance status assessed by a modified version of the Activity Assessment Scale. The primary outcome was incidence of chronic postoperative inguinal pain defined as moderate to severe pain-related impairment of everyday activities. Pain was registered according to the two individual groin areas. Furthermore, the overall incidence of chronic postoperative inguinal pain per operated inguinal hernia was calculated. Intensity of experienced pain (Activity Assessment Scale score) was compared between patients reporting pain from one versus both groin areas. RESULTS: In total, 209 patients (418 hernia repairs) were analyzed (questionnaire response rate 83%). The median follow-up time was 27 months (22-34 months). In total, 27 of 209 patients (13%) complained of chronic postoperative inguinal pain from either one (n = 17) or both (n = 10) groin areas after bilateral transabdominal preperitoneal inguinal hernia repair. The incidence of chronic inguinal pain per operated hernia was 9%. The intensity of impairment due to pain (Activity Assessment Scale score) did not differ significantly between patients with chronic postoperative inguinal pain in one (19%) versus both sides (30%), p = 0.056. CONCLUSION: Bilateral transabdominal preperitoneal inguinal hernia repair for symptomatic inguinal hernias was related to a high incidence (13%) of chronic postoperative inguinal pain and decreased functional performance status.

BACKGROUND & AIMS: Although incisional hernia repair in women of childbearing age is not rare, hernia disease in this group of patients is sparsely documented. The aim of this study was to examine long-term clinical results after incisional hernia repair in women of childbearing age. MATERIAL AND METHODS: This nationwide cohort study examined incisional hernia repair from 2007 to 2013 in women of childbearing age, registered prospectively in the Danish Ventral Hernia Database. All women with a subsequent pregnancy were included, and a 1:3 propensity-score matched group of women with an incisional hernia repair without a subsequent pregnancy. A prospective follow-up was conducted, including a validated questionnaire. The primary outcome was recurrence, and the secondary outcome was chronic pain from the operated site. RESULTS: In total, 124 (70.5%) women responded, 47 and 77 women with and without a subsequent pregnancy, respectively. The 5-year cumulative incidence of recurrence was 41.0% (95% confidence interval 32.0%-49.9%). After adjustment for potential confounders, subsequent pregnancy was independently associated with recurrence (hazard ratio 1.83, 95% confidence interval 1.02-3.29, p = 0.044). Twenty-six (21.0%) women reported chronic pain (moderate, n = 21; severe, n = 5) with no difference between women with and without a subsequent pregnancy. Hernia recurrence, higher body mass index, and smoking were associated with chronic pain. CONCLUSION: Pregnancy following incisional hernia repair was associated with an increased risk of recurrence, but not with chronic pain.

BACKGROUND AND AIMS: The use of mesh repair in a small- or middle-sized umbilical hernia remains controversial, and evidence is based on only few and small heterogeneous randomized trials. The primary aim was to assess differences, if any, in recurrence (clinical and reoperation), and secondary aim was to assess differences in infections, seroma formation, hematomas, chronic pain, cosmetic result, and quality of life. METHOD: A systematic review (predefined search strategy) and meta-analyses were conducted based on pre-study strict and well-defined methodology. The literature search was completed on 1 January 2018. The study protocol was registered in PROSPERO. RESULTS: Five randomized controlled trials were identified (mesh repair, n = 326 versus non-mesh sutured repair, n = 330) and 602 records were excluded. Randomized controlled trials included patients with defect diameters of ⩾1 to 4 cm. Mesh repair reduced the risk of recurrence compared with sutured repair with a relative risk of 0.28 (95% confidence interval = 0.13-0.58, I2 = 0%, number needed to treat = 13 patients). Additional analyses found no differences between the two surgical techniques regarding infection (relative risk = 0.80, 95% confidence interval = 0.36-1.79), seroma formation (relative risk = 1.38, 95% confidence interval = 0.57-3.32), or hematomas (relative risk = 0.55, 95% confidence interval = 0.23-1.30). Lack of sufficient data precluded meta-analysis evaluating risk of seroma formation, hematomas, chronic pain, cosmetic result, and quality of life. CONCLUSION: Mesh repair is recommended for umbilical hernia of ⩾1 to 4 cm. More evidence is needed for the optimal placement of the mesh (sublay or onlay) and the role of mesh in patients with an umbilical hernia <1 cm.

BACKGROUND: Traditionally, perforated diverticulitis with purulent peritonitis was treated with resection and colostomy (Hartmann's procedure), with inherent complications and risk of a permanent stoma. The DILALA (DIverticulitis - LAparoscopic LAvage versus resection (Hartmann's procedure) for acute diverticulitis with peritonitis) and other randomized trials found laparoscopic lavage to be a feasible and safe alternative. The medium-term follow-up results of DILALA are reported here. METHODS: Patients were randomized during surgery after being diagnosed with Hinchey grade III perforated diverticulitis at diagnostic laparoscopy. The primary outcome was the proportion of patients with one or more secondary operations from 0 to 24 months after the index procedure in the laparoscopic lavage versus Hartmann's procedure groups. The trial was registered as ISRCTN82208287. RESULTS: Forty-three patients were randomized to laparoscopic lavage and 40 to Hartmann's procedure. Patients in the lavage group had a 45 per cent reduced risk of undergoing one or more operations within 24 months (relative risk 0·55, 95 per cent c.i. 0·36 to 0·84; P = 0·012) and had fewer operations (ratio 0·51, 95 per cent c.i. 0·31 to 0·87; P = 0·024) compared with those in the Hartmann's group. No difference was found in mean number of readmissions (1·37 versus 1·50; P = 0·221) or mortality between patients randomized to laparoscopic lavage or Hartmann's procedure. Three patients in the lavage group and nine in the Hartmann's group had a colostomy at 24 months. CONCLUSION: Laparoscopic lavage is a better option for perforated diverticulitis with purulent peritonitis than open resection and colostomy.

BACKGROUND: Prevalence, management, and risk of emergency operation for primary ventral or groin hernia in pregnancy are unknown. The objective of this study was to estimate the prevalences of primary ventral or groin hernia in pregnancy and the potential risks for elective and emergency repair. METHODS: This single-institutional retrospective study included all pregnant women attending one or more prenatal consultations at Hvidovre Hospital, Denmark, during a 3-year period. Patients' medical records were electronically retrieved. A free-text search algorithm and subsequent manual review was conducted to identify patients registered with a primary ventral or groin hernia in pregnancy. Follow-up was conducted by review of medical record notes within the Capital Region of Denmark supplemented with structured telephone interviews on indication. RESULTS: In total, 20,714 pregnant women were included in the study cohort. Seventeen (0.08%) and 25 (0.12%) women were registered with a primary ventral and groin hernia, respectively. None underwent elective or emergency repair in pregnancy, and all had uncomplicated childbirth. In 10 women, the groin bulge disappeared spontaneously after delivery. During postpartum follow-up of median 4.4 years (range 0.2-6.0 years), five (0.02%) and four (0.02%) underwent elective primary ventral and groin hernia repair, respectively. CONCLUSION: Primary ventral or groin hernia seems rare in pregnancy, and the incidence of emergency repair is extremely low. Watchful waiting strategy is recommended during pregnancy in women suspected for a primary ventral or groin hernia.

BACKGROUND: Acute high-risk abdominal (AHA) surgery carries a very high risk of morbidity and mortality and represents a massive healthcare burden. The aim of the present study was to evaluate the effect of a standardized multidisciplinary perioperative protocol in patients undergoing AHA surgery. METHODS: The AHA study was a prospective single-centre controlled study in consecutive patients undergoing AHA surgery, defined as major abdominal pathology requiring emergency laparotomy or laparoscopy including reoperations after elective gastrointestinal surgery. Consecutive patients were included after initiation of the AHA protocol as standard care. The intervention cohort was compared with a predefined, consecutive historical cohort of patients from the same department. The protocol involved continuous staff education, consultant-led attention and care, early resuscitation and high-dose antibiotics, surgery within 6 h, perioperative stroke volume-guided haemodynamic optimization, intermediate level of care for the first 24 h after surgery, standardized analgesic treatment, early postoperative ambulation and early enteral nutrition. The primary outcome was 30-day mortality. RESULTS: Six hundred patients were included in the study and compared with 600 historical controls. The unadjusted 30-day mortality rate was 21·8 per cent in the control cohort compared with 15·5 per cent in the intervention cohort (P = 0·005). The 180-day mortality rates were 29·5 and 22·2 per cent respectively (P = 0·004). CONCLUSION: The introduction of a multidisciplinary perioperative protocol was associated with a significant reduction in postoperative mortality in patients undergoing AHA surgery.

BACKGROUND: The hypothesis was that groin hernias are hereditary. This study was undertaken to establish the degree of familial clustering of groin hernias on a nationwide scale. METHODS: A register-based cohort was created consisting of all children in Denmark whose parents were born in 1970 or later by the use of the Danish Civil Registration System. Within this cohort, all groin hernia operations were identified. To establish the risk estimates associated with a positive family history of groin hernia operation, information on groin hernia operations in fathers, mothers and siblings was also assessed. RESULTS: In the cohort of 408 381 persons, a total of 4966 were operated on for groin hernia (incidence rate 2·12 per 1000 person-years at risk). A person with a mother who had undergone surgery for a groin hernia had an increased risk of 2·89 (95 per cent c.i. 2·48 to 3·34) of having a groin hernia operation; a person with a father operated on for a groin hernia had an increased risk of 1·75 (1·58 to 1·94); and a person with a sibling operated on for a groin hernia had an increased risk of 2·54 (2·17 to 2·96). The strongest association was seen between mothers who had been operated on for groin hernia and their daughters (increased risk 6·01, 95 per cent c.i. 4·53 to 7·80), compared with the risk in girls who did not have a mother who had undergone surgery for groin hernia. CONCLUSION: Groin hernias are clustered in families, with the strongest relationship seen between mothers and their daughters.
ABSTRACT
PURPOSE: Umbilical and epigastric hernia repair are common surgical procedures; however, the nationwide gender and age-specific prevalence of these repairs is unknown, and this knowledge could form the basis for new studies. METHODS: A nationwide register-based study covering all people living in Denmark on December 31st, 2010 was performed. Within this population all umbilical and epigastric hernia repairs from January 1st, 2006 to December 31st, 2010 were identified using data from the Danish National Hospital Register, and 5-year prevalence estimates were calculated. RESULTS: The study population covered 5,639,885 persons (49 % males). A total of 10,107 patients (68 % males) were operated for an umbilical hernia and 2412 patients (55 % males) were operated for an epigastric hernia. The age-specific 5-year prevalence differed for both hernia types. The highest 5-year prevalence of umbilical hernia repairs was seen in males aged 60-70 years with a 5-year prevalence of 0.53 % (95 % CI 0.51-0.56 %) and the highest age-specific 5-year prevalence of epigastric hernia repair was seen in 40-50 year females with a 5-year prevalence of 0.086 % (95 % CI 0.077-0.095 %). CONCLUSION: The gender and age-specific 5-year prevalence of umbilical and epigastric hernia repair differed in a nationwide population.

BACKGROUND: The mesh fixation technique in laparoscopic incisional hernia repair may influence the rates of hernia recurrence and chronic pain. This study investigated the long-term risk of recurrence and chronic pain in patients undergoing laparoscopic incisional hernia repair with either absorbable or non-absorbable tacks for mesh fixation. METHODS: This was a nationwide consecutive cohort study based on data collected prospectively concerning perioperative information and clinical follow-up. Patients undergoing primary, elective, laparoscopic incisional hernia repair with absorbable or non-absorbable tack fixation during a 4-year interval were included. Follow-up was by a structured questionnaire regarding recurrence and chronic pain, supplemented by clinical examination, and CT when indicated. Recurrence was defined as either reoperation for recurrence or clinical/radiological recurrence. RESULTS: Of 1037 eligible patients, 84·9 per cent responded to the questionnaire, and 816 were included for analysis. The median observation time for the cohort was 40 (range 0-72) months. The cumulative recurrence-free survival rate was 71·5 and 82·0 per cent after absorbable and non-absorbable tack fixation respectively (P = 0·007). In multivariable analysis, the use of absorbable tacks was an independent risk factor for recurrence (hazard ratio 1·53, 95 per cent c.i. 1·11 to 2·09; P = 0·008). The rate of moderate or severe chronic pain was 15·3 and 16·1 per cent after absorbable and non-absorbable tack fixation respectively (P = 0·765). CONCLUSION: Absorbable tack fixation of the mesh was associated with a higher risk of recurrence than non-absorbable tacks for laparoscopic mesh repair of incisional hernia, but did not influence chronic pain.
