- Abstract
Purpose: Bochdalek hernia is a congenital diaphragmatic hernia. The incidence in adults is estimated around 0.17%. Right-sided hernias are much more seldom than left-sided ones because of faster closure of the right pleuroperitoneal canal and the protective effect of the liver. Due to its rarity, there have been no large prospective or retrospective studies following great need for evidence-based diagnostics and treatment strategies. In this systematic review, we evaluated the current evidence of diagnostics, treatment, and follow-up of adult right-sided Bochdalek hernias., Methods: According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines a systematic literature review was conducted in PubMed and Cochrane library from 2004 to January 2021. The literature search included all studies with non-traumatic right-sided Bochdalek hernias. Literature on left- or both-sided, pregnancy-associated, pediatric, and other types of hernias were explicitly excluded. Quality assessment of the included studies was performed., Results: Database search identified 401 records. After eligibility screening 41 studies describing 44 cases of right-sided non-traumatic Bochdalek hernias in adulthood were included for final analysis. Based upon the systematic literature review, the current diagnostic, therapeutic, and follow-up management pathway for this rare surgical emergency is presented., Conclusion: This systematic review underlined that most studies investigating management of adult non-traumatic right-sided Bochdalek hernias are of moderate to low methodological quality. Hernias tend to occur more frequently in middle-aged and older women presenting with abdominal pain and dyspnea. A rapid and accurate diagnosis following surgical repair and regular follow-up is mandatory. High-quality studies focusing on the management of this rare entity are urgently needed., (© 2021.

- Abstract
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.

- Abstract
Introduction: Inguinal hernias are among the most common surgical diseases in Africa. The current International HerniaSurge Guidelines recommend mesh-based surgical techniques in Low Resource Settings (LRS). This recommendation is currently unachievable in large parts of Africa due to the unaffordability of mesh and lack of appropriate training of the few available surgeons. There is, therefore, a need for formal training in mesh surgery. There is an experience in Hernia Repair for the Underserved in Central and South America, however, inadequate evidence of structured training in Africa., Material and Methods: Since 2016, the aid Organizations, Surgeons for Africa and Operation Hernia have developed and employed a structured hernia surgical training program for postgraduate surgical trainees and medical doctors in Rwanda. This course consists of lectures on relevant aspects of hernia surgery and hands-on training in operating theatres. The lectures emphasize anatomy and surgical technique. All parts of the training were evaluated. Formal pre-course evaluation was conducted to assess the personal surgical experience of the trainees., Results: Over a 3-year period, a structured hernia training programme was employed to train a total of 36 surgical trainees in both mesh and also non mesh hernia surgery. The key principle in this course is the continuous competence assessment and feedback. Evidence is provided to demonstrate improvement in surgical skills as well as knowledge of surgical anatomy which is essential to acquiring surgical competency. With self-assessment, expressed on a Likert scale, the participants could improve the theoretical knowledge about hernias from median 4.4 (on a scale of 1-10) before training to 8.4 after the training. The specific knowledge about anatomy could be improved in the same assessment from 4.8 before training to 8.1. after the training. After training course 12 of the 36 participants (33.33%) were able to carry out both suture- and mesh-based operations of simple inguinal hernias completely and independently. 20 of the 36 participants (55.55%) required only minimal supervision and only four participants (11.11%) required surgical supervision even after the completion of the course., Conclusion: We have demonstrated that, medical personnel in Africa can be trained in mesh and non-mesh hernia surgery using a structured training programme.

- Abstract
Purpose: Retromuscular mesh augmentation is generally considered to be the ideal technique for repairing ventral hernias and can be performed laparoscopically by 'enhanced view totally extraperitoneal plasty' (eTEP)-a technically complex procedure that requires a high level of surgical expertise. We aimed to develop a simplified technical modification., Methods: Thirty-one patients with ventral hernias were operated with a modified precostal, top-down eTEP approach, and prospectively recorded in our hernia registry. We describe this novel standardized precostal access and the bilateral development of both retromuscular compartments with a cylindrical dilating balloon port. Demographic-, hernia-specific-, and perioperative data were analyzed retrospectively., Results: Twenty-two primary and 9 incisional hernias with an average defect size of 34.5 cm
2 were repaired. An average implant of 420 cm2 always completely covered diastasis recti and/or scars from previous midline laparotomies. Average procedure time was 128 min. One conversion was required due to peritoneal injury. Postoperatively there was one local infection and one patient suffered an interparietal herniation. There were no recurrences during the average 8-month follow-up period., Conclusion: With technical modification of precostal access and pneumatic balloon dilation of both retro-rectus compartments, the complex procedure can be simplified through time saving and straightforward unidirectional 'top-down' dissection. The better overview facilitates the crossover for connecting both retro-rectus spaces. In addition, the cranial access allows the anterior- and posterior layers to be closed up to the xiphoid.- Published

- Abstract
Purpose: Short-term effects of round ligament varicosity (RLV) in pregnancy have been investigated in small-scale studies. The long-term effects are unknown. This study aims to evaluate the risk of groin hernia manifestation after RLV in pregnancy, to delineate possible risk factors and to analyze the natural course of pregnancy and post-partum period with regard to RLV., Methods: In a prospective analysis 28 pregnant women with RLV presented to the hernia clinic over 9 years. After clinical and ultrasound examination during pregnancy and publication of early results in 2013 a second structured follow-up was conducted. Demographic data, hernia-specific risk factors, comorbidities, pregnancy and birth-related data as well as post-partum period were documented without loss of follow-up. In these women, all pregnancies that occurred, including the ones without RLV, were analyzed., Results: Median follow-up was 68 months (11.4-104.9). Only one groin hernia was found. No risk factors could be identified. After uncomplicated childbirth complaints subsided spontaneously in all but one patient within 4 weeks. Recurrence rates in subsequent pregnancies are up to 89%., Conclusion: Temporary RLV-induced dilation of the deep inguinal ring in pregnancy is not a common precursor for the development of inguinal hernias later in life. All findings support the theory that the hindrance of venous blood flow caused by the gravid uterus is an important contributing factor for RLV in pregnancy, which is self-limited but has a high risk of recurrence and is not an indication for surgery before or after delivery or for cesarean section.

- Abstract
Purpose: Knowledge of postoperative behavior of mesh implants used for hernia repair is generally limited to cases of recurrence, local complications or return to the previous operative field in other pathological conditions. Previous studies with MRI-visible mesh implants in different parts of the abdominal wall have led to variable findings with regard to mesh properties and mostly described a reduction in size over time with subsequently limited mesh overlap over hernia defects which could contribute to recurrence. We aimed to evaluate implant properties in a mechanically stable anatomical region after TAPP repair of primary unilateral inguinal hernias in men with clinical and MRI examinations 4 weeks and 1 year after surgery., Methods: From 11/2015 to 01/2019, 23 men with primary, unilateral, inguinal hernias underwent TAPP repair with iron particle-loaded, MRI-visible mesh implants in a prospective cohort study. In 16 patients the operative outcome could be evaluated 4 weeks and 12 months after surgery by clinical examination and MRI evaluation with regard to postoperative course, possible adverse outcomes and radiological findings related to implant behavior-namely MRI-identifiability, mesh dislocation or reduction in surface area., Results: All included patients had an uneventful postoperative clinical course. MRI after 4 weeks revealed one postoperative seroma, which resolved spontaneously. No recurrence was detected. Mesh implants could be accurately delineated in DIXON-IN studies and showed neither clinically nor statistically significant changes in size or position., Conclusion: 4 weeks and 1 year after a standardized TAPP procedure the mesh implant used in this study showed no tendency towards dislocation or reduction in size in this anatomical position. Its MRI visibility allows accurate delineation during the postoperative course by experienced radiologists in appropriate MRI protocols. Larger patient series are desirable to further support these findings. Shrinkage of implants in the groin as a reason for early recurrence may be overestimated.

- Abstract
Background: In inguinal hernia repair, chronic pain must be expected in 10-12% of cases. Around one-quarter of patients (2-4%) experience severe pain requiring treatment. The risk factors for chronic pain reported in the literature include young age, female gender, perioperative pain, postoperative pain, recurrent hernia, open hernia repair, perioperative complications, and penetrating mesh fixation. This present analysis of data from the Herniamed Hernia Registry now investigates the influencing factors for chronic pain in male patients after primary, unilateral inguinal hernia repair in TAPP technique., Methods: In total, 20,004 patients from the Herniamed Hernia Registry were included in uni- and multivariable analyses. For all patients, 1-year follow-up data were available., Results: Multivariable analysis revealed that onset of pain at rest, on exertion, and requiring treatment was highly significantly influenced, in each case, by younger age (p < 0.001), preoperative pain (p < 0.001), smaller hernia defect (p < 0.001), and higher BMI (p < 0.001). Other influencing factors were postoperative complications (pain at rest p = 0.004 and pain on exertion p = 0.023) and penetrating compared with glue mesh fixation techniques (pain on exertion p = 0.037)., Conclusions: The indication for inguinal hernia surgery should be very carefully considered in a young patient with a small hernia and preoperative pain.

- Abstract
Background: Adhesion formation remains an important issue in hernia surgery. Liquid agents were developed for easy and versatile application, especially in laparoscopy. The aim of this study was to compare the antiadhesive effect of fibrin sealant (FS, Artiss
® ), Icodextrin (ID, Adept® ) and Polyethylene glycol (PEG, CoSeal® ) alone and in combination and to evaluate the resulting effect on tissue integration of the mesh., Methods: A total of 56 Sprague-Dawley rats were operated in open IPOM technique. A middleweight polypropylene mesh of 2 × 2 cm size was implanted and covered with 1: FS, 2: ID, 3: PEG, 4: FS + ID, 5: FS + PEG, 6: PEG + ID, 7: control group, uncovered mesh (n = 8 per treatment/control). Observation period was 30 days. Macroscopic and histological evaluation was performed., Results: Severe adhesions were found in group 2 (ID), group 6 (PEG + ID) and the controls. Best results were achieved with FS alone or FS + ID. Mesh integration in the treatment groups was reduced in comparison with the control group. This is a new finding possibly relevant for the outcome of intraperitoneal mesh repair. Group 6 (PEG + ID) showed an impairment of tissue integration with <50 % of the mesh surface in seven samples., Conclusion: FS alone and in combination with ID yielded excellent adhesion prevention. ID alone did not show significant adhesion prevention after 30 days. Tissue integration of FS-covered meshes was superior to ID or PEG alone or combined. PEG did show adhesion prevention comparable to FS but evoked impaired tissue integration. So Artiss® is among the most potent antiadhesive agents in IPOM repair.- Published

- Abstract
Introduction: Negative pressure wound therapy (NPWT) is widely used in the treatment of open abdomen (OA). The use of dynamic fascial sutures (DFS) increases the rate of successful delayed closure by reducing fascial lateralization. We recently published a prospective controlled trial including 87 patients undergoing abdominal surgery for secondary peritonitis between 2007 and 2012. Patients were treated with NPWT and DFS for approximation of fascial edges. The present study represents a follow-up assessment of these patients 5-9 years after OA treatment with NPWT and DFS., Methods: The 39 patients still alive were included in the recent study according to the protocol of our last study in 2013. All patients received a questionnaire regarding long-term complications after OA treatment between 2007 and 2012. Mean follow-up was 5-9 years. Analyzed parameters included pain, the presence of incisional hernia, and subsequent surgical interventions. Results were analyzed quantitatively., Results: One patient had deceased since the last publication in 2013, and hence 38 patients were included in the current study. The median age was 60.9 (25.2-86.1) years, and 17 (44.7%) were females. Overall 56.3% of the original 87 patients had died during the long-term follow-up period. 21 patients (55.3%) answered the questionnaire. Six (28.6%) declared that they suffered from pain in the previous operating field, five (23.8%) at rest, and three (14.3%) during exercise. In five patients (23.8%), pain lasted for more than 3 months. One patient (4.8%) still requires analgesic treatment. Among the 21 patients, seven (33.3%) were found to have incisional hernias. Three hernias (42.9%) were treated by surgery., Conclusion: Incisional hernia rates after OA treatment remain high, but are accompanied by little pain. The ideal technique of fascial closure after NPWT should be investigated in further research.

- Abstract
Whereas for TEP the guidelines do not recommend mesh fixation on the basis of meta-analyses regardless of the defect size, for TAPP mesh fixation can be omitted only up to a defect size of 3 cm because of the paucity of studies on this topic. Hence, this study now seeks to explore this subject on the basis of prospective data from the Herniamed Hernia Registry. In the period September 01, 2009, to January 31, 2014, 11,228 male patients were operated on with the TAPP technique for a primary unilateral inguinal hernia and were followed up for 1 year. Mesh fixation was used for 7422 (66.1 %) of these patients and no mesh fixation for 3806 patients (33.9 %). Unadjusted analysis did not find any significant difference in the recurrence rate (0.88 % with fixation vs. 1.1 % without fixation; p = 0.259). Multivariable analysis of all potential influence factors (age, ASA, BMI, risk factors, defect size, mesh fixation, localization of defect, mesh size) did not identify any factor that impacted recurrence on 1-year follow-up. Only for medial and combined defect localization versus lateral localization was a highly significant effect identified (p < 0.001). With mesh fixation and larger mesh size, it was possible to significantly reduce the recurrence rate for larger medial hernias in this series (p = 0.046). For TAPP repair of an inguinal hernia, mesh fixation is not necessary in a significant number of patients. Patients with a medial and combined hernia are at higher risk of recurrence. In the patient series analyzed, it was possible to significantly reduce the recurrence rate with mesh fixation and larger mesh size for medial defects.

- Abstract
Purpose: In open inguinal hernia repair self-gripping meshes are currently commonly employed. Assumed benefits are saving of time, ease of handling and omission of fixation. Self-gripping meshes are, however, not as easy to handle and position as commonly stated. We describe a newly developed way of intra-operative mesh preparation and implantation and compare it to the conventional technique of insertion of self-gripping meshes., Methods: A two-armed, randomized trial with 64 patients was performed. For implantation of the self-gripping, light weight and partially absorbable mesh we used either a newly described rolling technique (group 1: n = 32) or the conventional way of insertion (group 2: n = 32). Primary endpoints of the study were feasibility with regard to actual implantation time and surgeons' satisfaction with the methods. Secondary endpoints were total operating time, length of hospital stay, postoperative pain, duration of pain medication intake and postoperative morbidity. In addition all patients were prospectively followed up according to the Hernia Med® registry's standards., Results: Implantation time (seconds) 140 ± 74 vs. 187 ± 84, p = 0.008, duration of pain medication intake (days) 3.6 ± 2.8 vs. 4.8 ± 2.6; p = 0.046 and postoperative morbidity 2 (6%) vs. 8 (25%) was significantly beneficial in group 1 (rolling technique) compared to group 2 (conventional method). Blinded questionnaire revealed that rolling the mesh is generally easier with less repositioning maneuvers than conventional placement. Neither overall procedure time, length of stay nor postoperative pain scores differed significantly between groups., Conclusion: The newly introduced rolling technique for the actual placement of self-gripping meshes in open inguinal hernia repair is technically less demanding and therefore significantly faster when compared to the conventional way of insertion of the same product. In addition the rolling technique has shown to be safe for the patients and to also provide higher surgeons' satisfaction.

- Abstract
Purpose: In patients with terminal ostomies, parastomal hernias (PSHs) occur on a frequent basis. They are commonly associated with various degrees of complaints and occasionally lead to life-threatening complications. Various strategies and measures have been tested and evaluated, but to date there is a lack of published evidence with regard to the best surgical technique for the prevention of PSH development., Methods: We conducted a retrospective analysis of prospectively collected data of eighty patients, who underwent elective permanent ostomy formation between 2009 and 2014 by means of prophylactic implantation of a three-dimensional (3D) funnel mesh in intraperitoneal onlay (IPOM) position., Results: PSH developed in three patients (3.75%). No mesh-related complications were encountered and none of the implants had to be removed. Ostomy-related complications had to be noted in seven (8.75%) cases. No manifestation of ostomy prolapse occurred. Follow-up time was a median 21 (range 3-47) months., Conclusion: The prophylactical implantation of a specially shaped, 3D mesh implant in IPOM technique during initial formation of a terminal enterostomy is safe, highly efficient and comparatively easy to perform. As opposed to what can be achieved with flat or keyhole meshes, the inner boundary areas of the ostomy itself can be well covered and protected from the surging viscera with the 3D implants. At the same time, the vertical, tunnel-shaped part of the mesh provides sufficient protection from an ostomy prolapse. Further studies will be needed to compare the efficacy of various known approaches to PSH prevention.

- Abstract
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.

- Abstract
Purpose: Mesh repair of large hiatal hernias has increasingly gained popularity to reduce recurrence rates. Integration of iron particles into the polyvinylidene fluoride mesh-based material allows for magnetic resonance visualisation (MR)., Methods: In a pilot prospective case series eight patients underwent surgical repair of hiatal hernias repair with pre-shaped meshes, which were fixated with fibrin glue. An MR investigation with a qualified protocol was performed on postoperative day four and 3 months postoperatively to evaluate the correct position of the mesh by assessing mesh appearance and demarcation. The total MR-visible mesh surface area of each implant was calculated and compared with the original physical mesh size to evaluate potential reduction of the functional mesh surfaces., Results: We documented no mesh migrations or dislocations but we found a significant decrease of MR-visualised total mesh surface area after release of the pneumoperitoneum compared to the original mesh size (mean 78.9 vs 84 cm(2); mean reduction of mesh area = 5.1 cm(2), p < 0.001). At 3 months postoperatively, a further reduction of the mesh surface area could be observed (mean 78.5 vs 78.9 cm(2); mean reduction of mesh area = 0.4 cm(2), p < 0.037)., Conclusion: Detailed mesh depiction and accurate assessment of the surrounding anatomy could be successfully achieved in all cases. Fibrin glue seems to provide effective mesh fixation. In addition to a significant early postoperative decrease in effective mesh surface area a further reduction in size occurred within 3 months after implantation.

- Abstract
Introduction: Transabdominal preperitoneal hernioplasty (TAPP) is a common procedure for groin hernia repair in adults. The peritoneal closure after mesh placement can be performed in various ways. In any case, thorough closure is recommended to avoid mesh exposure to the viscera with the risk of adhesions and bowel incarceration into peritoneal defects. Postoperative intestinal obstructions can mainly occur due to adhesions or bowel herniation through peritoneal defects into the dissected preperitoneal space. Incarcerations can also occur as a consequence of trocar site herniation., Results and Conclusion: Recently barbed self-anchoring knotless suturing devices are frequently used for peritoneal closure. The correct handling of such sutures is crucial to avoid potential complications. Despite of accurate management, bowel adherence and injuries or volvulus can occur., Methods: We present an unusual case of a postoperative small bowel obstruction owing to strained adhesions and ingrowth between a small bowel segment and a polyglyconate unidirectional self-anchoring barbed suture device. Medline and PudMed databases were searched using the below-mentioned keywords and the literature on efficacy and safety of barbed sutures for peritoneal closure is reviewed as well as the usage of such devices in other fields of surgery.

- Abstract
Purpose: Parastomal hernias (PSHs) have been a major clinical problem. The aim of this study was to evaluate a new method of PSH repair in combination with an additional flat mesh reinforcement of the abdominal wall., Methods: In a pilot case series, seven patients suffering from complex PSHs (≥5 cm diameter and/or recurrence) underwent surgery and were treated by intraperitoneal onlay technique (IPOM) with a synthetic 3-D funnel-shaped mesh implant. The demographics, perioperative, and follow-up data are presented in this report., Results: The surgical strategy varied between purely laparoscopic (n = 1), laparoscopically assisted (hybrid n = 3), or open techniques (n = 3) using original or suture-reconstructed mesh devices. The funnel mesh implantations in IPOM technique were combined with attached flat meshes in the appropriate position of the abdominal wall. No procedure-related complications occurred. The mean length of hospital stay was 12 days and the mean operating time was 171 min. No recurrence of PSH or incisional hernias was observed during a mean follow-up period of 12.3 months (range from 7 to 22)., Conclusion: The use of a 3-D mesh implant has so far shown to be a promising option in the treatment of primary and recurrent PSHs. Its use proved to be reasonable in both laparoscopic and open IPOM technique. PSHs were preferably repaired using the original, unmodified implant, but when we also found it safe to incise, place and then suture the mesh around the pre-existing ostomy.

- Abstract
Purpose: With a newly described diagnostic pathway, we aim to avoid unnecessary surgical exploration for suspected symptomatic groin hernias in pregnancy., Methods: A consecutive series of eighteen pregnant women was referred to our department due to a gradual onset of inguinal swelling and groin ache. In a prospective clinical study, we evaluated these patients clinically and employed grey-scale and colour Doppler sonography (CDS) in all cases--following a newly described pathway. All patients were examined pre- and post-partum by two qualified surgeons. Median follow-up time was 11 months., Results: 4/18 of the suspected hernias first occurred towards the end of the first, the majority (12/18) in the second, 2/18 in the last trimester and all were suspected after clinical examination only. Most women were referred by their gynaecologists. We found no hernias in any of the women but always noted large varicose veins along the round ligament during CDS. All women gave uncomplicated birth to single children, one by caesarean section. Complaints subsided spontaneously within roughly 2 weeks after delivery. No patient developed a groin hernia until the end of the follow-up period., Conclusion: The diagnosis of an inguinal hernia with a first symptomatic onset during pregnancy may be wrong in most cases. Anamnesis and clinical examination must be backed by CDS and round ligament varicosity as an important differential diagnosis must always be considered. Our structured diagnostic pathway helps to easily make the correct diagnosis. Surgical exploration of the groin during pregnancy must be avoided.
