RESUMO
INTRODUCTION: Immunosuppressive conditions and/or preoperative corticosteroid treatment have a negative influence on wound healing and can, therefore, lead to higher rates of surgical site infections (SSIs) and seromas. For inguinal hernia, no such studies have been carried out to date. METHODS: In an analysis of data from the Herniamed Registry, 2312 of 142,488 (1.6%) patients with primary unilateral inguinal hernia repair had an anamnestic history of an immunosuppressive condition and/or preoperative corticosteroid treatment. Using propensity score matching, 2297 (99.4%) pairs with comparative patient characteristics were formed. These were then compared using the following primary outcome criteria: intra- and postoperative complications, complication-related reoperations, recurrence at one-year follow-up, pain on exertion, pain at rest, and chronic pain requiring treatment at one-year follow-up. Of the 2297 matched pairs with primary unilateral inguinal hernia repair, 82.76% were male patients. 1010 (44.0%) were operated in laparo-endoscopic techniques (TEP, TAPP), 1225 (53.3%) in open techniques (Bassini, Shouldice, Lichtenstein, Plug, TIP, Gilbert, Desarda), and 62 (2.7%) in other techniques. RESULTS: The matched pair analysis results did not identify any disadvantage in terms of the outcome criteria for patients with an anamnestic history of immunosuppressive condition and/or preoperative corticosteroid treatment (yes vs no). In particular, no disadvantage was noted in the rate of surgical site infections (0.65% vs 0.70%; ns) or seromas (1.22% vs 1.57%; ns). The overall rates of postoperative complications were 3.40% vs 4.31% (p = ns) (plus 0.22% concordant events in five matched pairs). CONCLUSION: In primary unilateral inguinal hernia surgery, an immunosuppressive condition and/or preoperative corticosteroid treatment does not appear to have a negative influence on wound complications.

BACKGROUND: For comparison of laparoscopic IPOM versus sublay technique for elective incisional hernia repair, the number of cases included in randomized controlled trials and meta-analyses is limited. Therefore, an urgent need for more comparative data persists. METHODS: In total, 9907 patients with an elective incisional hernia repair and 1-year follow-up were selected from the Herniamed Hernia Registry between September 1, 2009 and June 1, 2016. Using propensity score matching, 3965 (96.5%) matched pairs from 4110 laparoscopic IPOM and 5797 sublay operations were formed for comparison of the techniques. RESULTS: Comparison of laparoscopic IPOM versus open sublay revealed disadvantages for the sublay operation regarding postoperative surgical complications (3.4% vs. 10.5%; p < 0.001), complication-related reoperations (1.5% vs. 4.7%; p < 0.001), and postoperative general complications (2.5% vs. 3.7%; p = 0.004). The majority of surgical postoperative complications were surgical site infection, seroma, and bleeding. Laparoscopic IPOM had disadvantages in terms of intraoperative complications (2.3% vs. 1.3%; p < 0.001), mainly bleeding, bowel, and other organ injuries. No significant differences in the recurrence and pain rates at 1-year follow-up were observed. CONCLUSION: Laparoscopic IPOM was found to have advantages over the open sublay technique regarding the rates of both surgical and general postoperative complications as well as complication-related reoperations, but disadvantages regarding the rate of intraoperative complications.

BACKGROUND: The reported range of seroma formation in the literature after TEP repair is between 0.5 and 12.2% and for TAPP between 3.0 and 8.0%. Significant clinical factors associated with seroma formation include old age, a large hernia defect, an extension of the hernia sac into the scrotum, as well as the presence of a residual indirect sac. Seroma formation is a frequent complication of laparoendoscopic mesh repair of moderate to large-size direct (medial) inguinal hernia defects. This present analysis of data from the Herniamed Hernia Registry now explores the influencing factors for seroma formation in male patients after TAPP repair of primary unilateral inguinal hernia. METHODS: In total, 20,004 male patients with TAPP repair of primary unilateral inguinal hernia were included in uni- and multivariable analysis. RESULTS: Univariable analysis revealed the highly significant impact of the fixation technique on the seroma rate (non-fixation 0.7% vs. tacks 2.1% vs. glue 3.9%; p < 0.001). Multivariable analysis showed that glue compared to tacks (OR 2.077 [1.650; 2.613]; p < 0.001) and non-fixation (OR 5.448 [4.056; 7.317]; p < 0.001) led to an increased seroma rate. A large hernia defect (III vs. I: OR 2.868 [1.815; 4.531]; p < 0.001; II vs. I: OR 2.157 [1.410; 3.300]; p < 0.001) presented a significantly higher risk of seroma formation. Likewise, medial compared to lateral inguinal hernias had a higher seroma rate (OR 1.272 [1.020; 1.585]; p = 0.032). CONCLUSIONS: Mesh fixation with tacks or glue, a larger hernia defect, and medial defect localization present a higher risk for seroma development in TAPP inguinal hernia repair.

BACKGROUND: In the new international guidelines only the mesh-based Lichtenstein, TEP and TAPP techniques are recommended. This present analysis of data from the Herniamed Registry compares the outcome for Shouldice versus Lichtenstein, TEP and TAPP. METHODS: Propensity score matching analyses were performed to obtain homogeneous comparison groups for Shouldice versus Lichtenstein (n = 2115/2608; 81.1%), Shouldice versus TEP (n = 2225/2608; 85.3%) and Shouldice versus TAPP (2400/2608; 92.0%). RESULTS: The most important characteristics of the Shouldice patient collective were younger patients with a mean age of 40 years, a large proportion of women of 30%, a mean BMI value of 24 and a proportion of defect sizes up to 3 cm of over 85%. For this selected patient collective, propensity score matched-pair analysis did not identify any difference in the perioperative and one-year follow-up outcome compared with TAPP, fewer intraoperative (0.5 vs. 1.3%; p = 0.009) but somewhat more postoperative complications (2.3 vs. 1.5%; p = 0.050) compared with TEP and advantages with regard to pain at rest (4.6 vs. 6.1%; p = 0.039) and on exertion (10.0 vs. 13.4%; p < 0.001) compared with the Lichtenstein technique. CONCLUSION: For a selected group of patients the Shouldice technique can be used for primary unilateral inguinal hernia repair while achieving an outcome comparable to that of Lichtenstein, TEP and TAPP operations.

INTRODUCTION: Comparison of elective laparoscopic repair of axial vs paraesophageal hiatal hernias reveals relevant differences in both the patient collectives and the complexity of the procedures. MATERIALS AND METHODS: The present uni- and multivariable analysis of data from the Herniamed Registry compares the outcome for 2047 (67.3%) (type I) axial with 996 (32.7%) (types II-IV) paraesophageal primary hiatal hernias following laparoscopic repair. RESULTS: Compared with the patients with axial hiatal hernias, patients with paraesophageal hiatal hernia were nine years older, had a higher ASA score (ASA III/IV: 34.8 vs 13.7%; p < 0.001), and more often at least one risk factor (38.8 vs 21.4%; p < 0.001). This led in the univariable analysis to significantly more general postoperative complications (6.0 vs 3.0%; p < 0.001). Reflecting the greater complexity of the procedures used for laparoscopic repair of paraesophageal hiatal hernias, significantly higher intraoperative organ injury rates (3.7 vs 2.3%; p = 0.033) and higher postoperative complication-related reoperation rates (2.1 vs 1.1%; p = 0.032) were identified. Univariable analysis did not reveal any significant differences in the recurrence and pain rates on one-year follow-up. Multivariable analysis did not find any evidence that the use of a mesh had a significant influence on the recurrence rate. CONCLUSION: Surgical repair of paraesophageal hiatal hernia calls for an experienced surgeon as well as for corresponding intensive medicine competence because of the higher risks of general and surgical postoperative complications.

INTRODUCTION: Inguinal hernia operations in the presence of antithrombotic therapy, based on antiplatelet or anticoagulant drugs, or existing coagulopathy are associated with a markedly higher risk for onset of postoperative secondary bleeding. To date, there is a paucity of concrete data on this important clinical aspect of inguinal hernia surgery. Up till now, the endoscopic (TEP, TAPP) techniques have been considered to be more risky because of the extensive dissection involved. PATIENTS AND METHODS: Out of the 82,911 patients featured in the Herniamed Hernia Registry who had undergone inguinal hernia repair, 9115 (11 %) were operated on while receiving antithrombotic therapy or with existing coagulopathy. The implications of that risk profile for onset of postoperative bleeding were investigated in multivariable analysis. In addition, other influence variables were identified. RESULTS: The rate of postoperative secondary bleeding, at 3.91 %, was significantly higher in the risk group with coagulopathy or receiving antithrombotic therapy than in the group without that risk profile at 1.12 % (p < 0.001). Multivariable analysis revealed other influence variables which, in addition to coagulopathy or antithrombotic therapy, had a relevant influence on the occurrence of postoperative bleeding. These were open operation, a higher age, a higher ASA score, recurrence, male gender and a large hernia defect. Patients receiving antithrombotic therapy or with existing coagulopathy who undergo inguinal hernia operation have a fourfold higher risk for onset of postoperative secondary bleeding. Despite the extensive dissection required for endoscopic (TEP, TAPP) inguinal hernia repair, the risk of bleeding complications and complication-related reoperation appears to be lower.

INTRODUCTION: Several analyses of hernia registries have demonstrated that patients older than 65 years have significantly higher perioperative complication rates compared with patients up to the age of 65. To date, no special analyses of endoscopic/laparoscopic inguinal hernia surgery or of the relevant additional influence factors have been carried out. Besides, there is no definition to determine whether 65 years should really be considered to be the age limit. METHODS: In the Herniamed Hernia Registry, it was possible to identify 24,571 patients with a primary inguinal hernia and aged at least 16 years who had been operated on between September 1, 2009, and April 15, 2013, using either the TAPP technique (n = 17,214) or TEP technique (n = 7,357). Patients in the age group up to and including 65 years (≤65 years) were compared with those older than 65 years (>65 years) in terms of their perioperative outcome. That was done first using unadjusted analysis and then multivariable analysis. RESULTS: Unadjusted analysis revealed significantly different results for the intraoperative (1.19 vs 1.60%; p = 0,010), postoperative surgical (2.72 vs 4.59%; p < 0.001) and postoperative general complications (0.85 vs 1.98%; p < 0.001) as well as for complication-related reoperations (1.07 vs 1.37%; p = 0,044), which were more favorable in the ≤65 years age group. However, in multivariable analysis, it was not possible to confirm that for the intraoperative complications or the reoperations. Reoperations were needed more often for bilateral procedures (p < 0.001; OR 2.154 [1.699; 2.730]), higher ASA classification (IV vs I: p = 0.004; OR 6.001 [1.786; 20.167]), larger hernia defect and scrotal hernias. The impact of these factors, in addition to that of age >65 years, was also reflected in the postoperative complication rates. The age limit for increased onset of perioperative complication rates tends to be more than 80 rather than 65 years. CONCLUSION: The higher perioperative complication rate associated with endoscopic/laparoscopic inguinal hernia surgery in patients older than 65 years is of multifactorial genesis and is observed in particular as from the age of 80 years.

INTRODUCTION: More than 20 years since the introduction of TAPP and TEP into clinical routine, there is a lack of clarity due to conflicting comparative data. Therefore, more results from registries are needed. PATIENTS AND METHODS: A total of 17,587 patients were enrolled prospectively between September 1, 2009, and April 15, 2013, in the Herniamed registry. Of these patients, 10,887 (61.9%) had a TAPP and 6700 (38.1%) a TEP repair. The dependent variables were intra- and postoperative complication rates, number of reoperations as well as absolute and relative frequencies. The results of unadjusted analyses were verified via multivariable analyses. RESULTS: Multivariable analysis verified the results of unadjusted analysis, indicating that the surgical technique did not have any significant impact, also while taking account of other factors, on occurrence of intraoperative [p = 0.1648; OR = 1.214 (0.923; 1.596)] and general postoperative complications [p = 0.0738; OR = 1.315 (0.974; 1.775)]. Postoperative surgical complications [OR = 2.323 (1.882; 2.866); p < 0.0001] were noted more often after TAPP. Furthermore, the hernia defect size [p < 0.0001; I vs III: OR = 0.439 (0.313; 0.615), II vs III: OR = 0.712 (0.582; 0.872)] or scrotal [p < 0.0001; OR = 2.170 (1.501; 3.137)] hernia and age [p = 0.0002; 10-year OR = 1.135 (1.062; 1.213)] had a significant impact on the occurrence of postoperative complications. Complications were observed more commonly for larger hernia defects and a scrotal hernia. However, the difference in the postoperative complication rate between TEP and TAPP did not result in any difference in the reoperation rate (TEP 0.82% vs TAPP 0.90%; p = 0.6165). CONCLUSION: The intraoperative and general postoperative complication rates as well as the reoperation rate for complications show no significant difference between TEP and TAPP. The higher postoperative complication rate for TAPP, which could be managed conservatively, is partly explained by larger defect sizes, more scrotal hernias and older age.

INTRODUCTION: The use of antibiotic prophylaxis in inguinal hernia repair is a controversial issue. Accepted randomized controlled trials or registry data with specific analysis of endoscopic repaired patients do not exist. PATIENT AND METHODS: The data presented in this study compared the prospectively collected data from the Herniamed Registry on all patients who had undergone unilateral, bilateral or recurrent repair of inguinal hernias using either endoscopic or open techniques between September 1, 2009, and March 5, 2014. In total, 85,033 patients were enrolled. Of these patients, 48,201 (56.7 ) had an endoscopic and 36,832 (43.3%) an open repair. The target variables analyzed were impaired wound healing and deep infections with mesh involvement within 30 days after the operation. RESULTS: Analysis of the patient group with endoscopic/laparoscopic inguinal hernia repair (n = 48,201) did not identify any significant influence of antibiotic prophylaxis on postoperative impaired wound healing, which occurred in 53 cases (p = 0.6431). Nor was it possible to identify any significant impact of antibiotic prophylaxis on the deep infections seen in 27 cases (p = 0.8409). Analysis of the open inguinal hernia repair group revealed that, unlike the laparoscopic/endoscopic group, antibiotic prophylaxis had a significant impact on the postoperative impaired wound healing and deep infection rates. The risk of postoperative impaired wound healing with antibiotic prophylaxis was significantly lower [OR 0.677 (0.479; 0.958), p = 0.027]. CONCLUSION: The positive impact of the endoscopic/laparoscopic technique on avoidance of impaired wound healing and deep infections with mesh involvement is already so great that antibiotic prophylaxis has no additional benefit. In contrast, antibiotic prophylaxis should be administered for open inguinal hernia repair.

INTRODUCTION: To date, no randomized controlled trials have been carried out to compare the perioperative outcome of unilateral and bilateral inguinal hernia repair using an endoscopic technique. In a Swiss registry study comparing unilateral with bilateral inguinal hernias, no further details were given regarding the nature of the intra- and postoperative complications. In addition, some authors have raised the issue of prophylactic repair of a clinically healthy other groin side. PATIENTS AND METHODS: In the Herniamed Registry, in total 9395 patients with a TEP were enrolled. These comprised 6700 patients with unilateral (71.31%) and 2695 patients (28.69%) with bilateral inguinal hernia repair. The outcome variables, analyzed in a multivariable model, were the intra- and postoperative as well as general complication rates, reoperation rate, duration of operation, and length of hospital stay. RESULTS: While no significant difference was found in the overall number of intraoperative complications between the unilateral and bilateral group (p=0.310), a significantly higher number of urinary bladder injuries in the bilateral TEP operation of 0.28% compared with 0.04% for unilateral TEP (p=0,008) were noted. The greater probability of reoperation (0.82% for unilateral vs. 1.78% for bilateral TEP; p<0,001) in the unadjusted analysis was confirmed in the multivariable model [OR 2.35 (1.504; 3.322); p=0.001]. A significantly higher intraoperative urinary bladder injury rate and reoperation rate because of postoperative surgical complications constitute a difference in the perioperative outcome between unilateral and bilateral TEP which that warrants attention. Based on these results, prophylactic operation of the healthy other groin should not be recommended.

BACKGROUND: Open sublay and laparoscopic IPOM repair have specific disadvantages and risks. In recent years, this evidence led to a paradigm shift and induced the development of new minimally invasive techniques of sublay mesh repair. METHODS: Pioneering this trend, we developed the endoscopically assisted mini- or less-open sublay (MILOS) concept. The operation is performed trans-hernially via a small incision with light-holding laparoscopic instruments either under direct, or endoscopic visualization. After dissection of an extra-peritoneal space of at least 8 cm, port placement and CO2 insufflation, each MILOS operation can be continued endoscopically (EMILOS repair). All E/MILOS operations were prospectively documented in the Herniamed Registry with 1- and 5-year questionnaire follow-ups. Propensity score matching of incisional hernia operations comparing the results of the E/MILOS operation with the laparoscopic intraperitoneal onlay mesh operation (IPOM) and open sublay repair from all other institutions participating in the Herniamed Registry was performed. The results with perioperative complications and 1-year follow-up have been published previously. RESULTS: This paper reports on the 5-year results. The 5-year follow-up rate was 87.5% (538 of 615 patients with E/MILOS incisional hernia operations). Comparing E/MILOS repair with laparoscopic IPOM and open sublay operation, propensity score matching analysis was possible with 448 and 520 pairs of operations, respectively. Compared with laparoscopic IPOM incisional hernia operation, the E/MILOS repair is associated with significantly fewer general complications (P = 0.004), recurrences (P < 0.001), less pain on exertion (P < 0.001), and less chronic pain requiring treatment (P = 0.016) and tends to result in fewer postoperative complications (P = 0.052), and less pain at rest (P = 0.053). Matched pair analysis with open sublay repair revealed significantly fewer general complications (P < 0.001), postoperative complications (P < 0.001), recurrences (P = 0.002), less pain at rest (P = 0.004), less pain on exertion (P < 0.001), and less chronic pain requiring treatment (P = 0.014). A limitation of this analysis is a relative low 5-year follow-up rate for laparoscopic IPOM and open sublay. CONCLUSIONS: The E/MILOS technique allows minimally invasive trans-hernial repair of incisional hernias using large standard meshes with low morbidity and good long-term results. The technique combines the advantages of sub-lay repair and a mini- or less-invasive approach. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT03133000.

INTRODUCTION: The debate continues as to whether laparoscopic total Nissen (LNF) versus partial posterior Toupet fundoplication (LTF) leads to better outcomes in the surgical treatment of axial hiatal hernia with gastroesophageal reflux disease. In the most recent meta-analysis including 13 RCTs with 1564 patients, no significant difference was found between the two procedures in terms of perioperative complications and recurrent reflux rates. Further comparative analyses are urgently needed. METHODS: This retrospective analysis of prospectively recorded data from the Herniamed Registry compared the perioperative and 1-year follow-up outcomes after total Nissen versus partial Toupet fundoplication. Propensity score matching was chosen as the statistical method. Matching was performed for n = 2290 pairs. RESULTS: No systematic discrepancy was found between the Nissen and Toupet fundoplication for any of the outcome parameters (intraoperative complications LNF 2.10% vs LTF 1.48%, general complications 2.27% vs 2.88%, postoperative complications 1.44% vs 1.18%, complication-related reoperation 1.00% vs 0.91%, recurrence on 1-year follow-up 6.55% vs 5.33%, pain on exertion on 1-year follow-up 12.49% vs 9.52%, pain at rest on 1-year follow-up 10.44 vs 9.52% and pain requiring treatment on 1-year follow-up 9.61% vs 8.17%). Also the postoperative dysphagia rate showed with 5.34% after LNF and with 4.64% after LTF no significant difference. CONCLUSION: The findings presented here did not show any significant difference up to 1 year after Nissen or Toupet fundoplication. This is in concordance with the findings of the meta-analyses. However, the perioperative and 1-year follow-up outcomes demonstrate that both operation techniques should be carried out by experienced surgeons.
RESUMO
INTRODUCTION: Surgical treatment of type I hiatal sliding hernias aims to control the gastroesophageal reflux symptoms and prevention of hernia recurrence. Usually, a cruroplasty is performed to narrow the hiatal orifice. Here, it remains controversial if a mesh reinforcement of the cruroplasty should be performed, since benefits as well as mesh-associated complications have been described. METHODS: We performed a propensity-score matching analysis with data derived from the Herniamed registry comparing patients undergoing laparoscopic type I hiatal hernia repair with and without synthetic mesh. We analyzed perioperative, intraoperative, and postoperative data including data derived from the 1-year follow-up in the registry. RESULTS: 6.533 patients with an axial, type I hiatal hernia and gastroesophageal reflux are included in this analysis. Mesh augmentation of the hiatoplasty was performed in n = 1.252/6.533 (19.2%) of patients. The defect size in the subgroup of patients with mesh augmentation was with mean 16.3 cm2 [14.5; 18.2] significantly larger as in the subgroups without mesh augmentation with 10.8 cm2 [8.7; 12.9]; (p < 0.001). In patients with mesh hiatoplasty n = 479 (38.3%) Nissen and n = 773 (61.7%) Toupet fundoplications are performed. 1.207 matched pairs could be analyzed. The mean defect size after matching was with 15.9 cm2 comparable in both groups. A significant association was seen regarding recurrence (4.72% mesh vs. 7.29% non-mesh hiatoplasty, p = 0.012). The same relation can be seen for pain on exertion (8.78% vs 12.10%; p = 0.014) and pain requiring treatment (6.13% vs 9.11%; p = 0.010). All other outcome parameter showed no significant correlation. CONCLUSIONS: Our data demonstrate that mesh-reinforced laparoscopic type I hiatal hernia repair in larger defects is associated with significantly lower rates for recurrence, pain on exertion and pain requiring treatment.
RESUMO
INTRODUCTION: Experimental data show that large-pored meshes reduce foreign body reaction, inflammation and scar bridging and thus improve mesh integration. However, clinical data on the effect of mesh porosity on the outcome of hernioplasty are limited. This study investigated the relation of pore size in polypropylene meshes to the outcome of Lichtenstein inguinal hernioplasty using data from the Herniamed registry. METHODS: This analysis of data from the Herniamed registry evaluated perioperative and 1-year follow-up outcomes in patients undergoing elective, primary, unilateral Lichtenstein inguinal hernia repair using polypropylene meshes. Patients operated with a non-polypropylene mesh or a polypropylene mesh with absorbable components were excluded. Polypropylene meshes with a pore size of 1.0 × 1.0 mm or less were defined as small-pored meshes, while a pore size of more than 1.0 × 1.0 mm was considered large-pored. Unadjusted analyses and multivariable analyses were performed to investigate the relation of pore size of polypropylene meshes, patient and surgical characteristics to the outcome parameters. RESULTS: Data from 22,141 patients were analyzed, of which 6853 (31%) were operated on with a small-pore polypropylene mesh and 15,288 (69%) with a large-pore polypropylene mesh. No association of mesh pore size with intraoperative, general or postoperative complications, recurrence rate or pain requiring treatment was found at 1-year follow-up. A lower risk of complication-related reoperation tended to be associated with small-pore size (p = 0.086). Furthermore, small-pore mesh repair was associated with a lower risk of pain at rest and pain on exertion at 1-year follow-up. CONCLUSION: The present study could not demonstrate an advantage of large-pore polypropylene meshes for the outcome of Lichtenstein inguinal hernioplasty.

PURPOSE: Every year around 70,000 people in Germany suffer from an abdominal incisional hernia that requires surgical treatment. Five years after reconstruction about 25% reoccur. Incisional hernias are usually closed with mesh using various reconstruction techniques, summarized here as standard reconstruction (SR). To improve hernia repair, we established a concept for biomechanically calculated reconstructions (BCR). In the BCR, two formulas enable customized patient care through standardized biomechanical measures. This study aims to compare the clinical outcomes of SR and BCR of incisional hernias after 1 year of follow-up based on the Herniamed registry. METHODS: SR includes open retromuscular mesh augmented incisional hernia repair according to clinical guidelines. BCR determines the required strength (Critical Resistance to Impacts related to Pressure = CRIP) preoperatively depending on the hernia size. It supports the surgeon in reliably determining the Gained Resistance, based on the mesh-defect-area-ratio, further mesh and suture factors, and the tissue stability. To compare SR and BCR repair outcomes in incisional hernias at 1 year, propensity score matching was performed on 15 variables. Included were 301 patients with BCR surgery and 23,220 with standard repair. RESULTS: BCR surgeries show a significant reduction in recurrences (1.7% vs. 5.2%, p = 0.0041), pain requiring treatment (4.1% vs. 12.0%, p = 0.001), and pain at rest (6.9% vs. 12.7%, p = 0.033) when comparing matched pairs. Complication rates, complication-related reoperations, and stress-related pain showed no systematic difference. CONCLUSION: Biomechanically calculated repairs improve patient care. BCR shows a significant reduction in recurrence rates, pain at rest, and pain requiring treatment at 1-year follow-up compared to SR.

BACKGROUND: Osteopenia (OP) or osteoporosis (OST) was diagnosed by bone densitometry (DXA) in postmenopausal women free of known skeletal disorders and without acute fracture. DVO guidelines were applied to define therapeutic indication. METHODS: The study included 94 women aged 59-81 years. Fracture or operation ≤12 months, malignant tumor, ovariectomy, and drugs such as cortisone, strontium, fluorides, bisphosphonates, SERMs, estrogens, and steroids were exclusion criteria. The lowest T-score at the spine, femoral neck, or total hip was decisive. The indication for therapy was determined by evaluating age, BMD, and other risk factors. RESULTS: Using the WHO criteria 22.3% (n=21) had normal BMD, 52.1% (n=49) had OP, and 25.6% (n=24) had OST. According to "Dachverband Osteologie" (DVO) guidelines, 28 women (29.8%) of the whole group needed therapy. Of the 28 women receiving therapy, 9 had OP and 19 had OST. Therapy was indicated in 18.4% for OP and 79.2% for OST. CONCLUSION: A preventive measurement of BMD with DXA provides a benefit for postmenopausal women. Combinatory assessment and consideration of other risk factors allows identification of women who might benefit from early treatment.

INTRODUCTION: Incisional hernias following lateral abdominal wall incisions with an incidence of 1-4% are less common than following medial incisions at 14-19%. The proportion of lateral incisional hernias in the total collective of all incisional hernias is around 17%. Compared to midline defects, lateral incisional hernias are more difficult to repair because of the more complex anatomy and localization. A recent systematic review identified only 11 publications with a total of 345 patients reporting on lateral incisional hernia repair. Therefore, further studies are urgently needed. METHODS: Multivariable analysis of the data available for 6,306 patients with primary elective lateral incisional hernia repair was performed to assess the confirmatory pre-defined potential influence factors and their association with the perioperative and one-year follow-up outcomes. RESULTS: In primary elective lateral incisional hernia repair, open onlay, open IPOM and suture procedures were found to have an unfavorable effect on the recurrence rate. This was also true for larger defect sizes and higher BMI. A particularly unfavorable relationship was identified between larger defect sizes and perioperative complications. Laparoscopic-IPOM presented a higher risk of intraoperative, and open sublay of postoperative, complications. The chronic pain rates were especially unfavorably influenced by the postoperative complications, preoperative pain and female gender. CONCLUSION: Open-onlay, open IPOM and suture procedures, larger defect sizes, female gender, higher BMI, preoperative pain and postoperative complications are associated with unfavorable outcomes following primary elective lateral incisional hernia repair.

PURPOSE: Elective open incisional hernia operations are a frequently performed and complex procedure. Prophylactic drainage is widely practised to prevent local complications, but nevertheless the benefit of surgical drain placement remains a controversially discussed subject. Objective of this analysis was to evaluate the current status of patient care in clinical routine and outcome in this regard. METHODS: The study based on prospectively collected data of the Herniamed Register. Included were all patients with elective open incisional hernia between 1/2005 and 12/2020 and completed 1-year follow-up. Multiple linear and logistic regression analysis was performed to assess the relation of individual factors to the outcome variables. RESULTS: Analysed were data from 39,523 patients (28,182 with drain, 11,341 without). Patients with drain placement were significantly older, had a higher BMI, more preoperative risk factors, and a larger defect size. Drained patients furthermore showed a significant disadvantage in the outcome parameters intraoperative complications, general complications, postoperative complications, complication-related reoperations, and pain at the 1-year follow-up. No significant difference was observed with respect to the recurrent rate. CONCLUSION: With 71.3%, the use of surgical drainages has a high level of acceptance in elective open incisional hernia operations. The worse outcome of patients is associated with the use of drains, independent of other influencing factors in the model such as patient or surgical characteristics. The use of drains may be a surrogate parameter for other unobserved confounders.
RESUMO
PURPOSE: The open Rives-Stoppa retrorectus and transversus abdominis release (TAR) techniques are well established in open ventral and incisional hernia repair. The principles are currently being translated into minimally invasive surgery with different concepts. In this study, we investigate our initial results of transperitoneal laparoscopic TAR for ventral incisional hernia repair (laparoscopic TAR). METHODS: Over a 20-month period, 23 consecutive patients with incisional hernias underwent surgery. Laparoscopic TAR was performed transperitoneally with adhesiolysis from the anterior abdominal wall, development of the retrorectus space and TAR, midline reconstruction and extraperitoneal mesh reinforcement. RESULTS: There were 23 incisional hernias, of which 70% were M2-M4 and 60% were W3. Median patient age was 68 years and the median BMI was 31. Median operating time was 313 min, and hospital stay was 4 days. Morbidity was 26% (Clavien-Dindo 1: n = 4 and 2 + 3b: n = 2). CONCLUSION: With the laparoscopic TAR, it was possible to treat a series of patients with ventral incisional hernias. The operating times were long. However, with a low rate of perioperative complications the hospital stay was short As feasibility is demonstrated, the clinical relevance of the method has to be further evaluated.
