A word of caution: never use tacks for mesh fixation to the diaphragm!

One-year outcomes of biological mesh in hiatal hernia repair: a real-world study

PURPOSE

The placement of synthetic mesh during laparoscopic hiatal hernia repair has been verified to reduce postoperative recurrence, but mesh erosion and other related complications may occur to synthetic mesh, and our aim was to verify the safety and efficacy of biological mesh in hiatal hernia repair.

METHODS

Patients with hiatal hernia who were treated at a tertiary teaching university hospital from December 2020 to May 2023 were prospectively included in this study. General clinical data, hernia-related data, and intraoperative data were collected, and the patients were followed up at 1, 3, 6, and 12 months after surgery, after 12 months, follow-up as needed for primary outcome until September 2024. The following parameters were recorded during follow-up visit: gastroesophageal reflux symptoms, Gastroesophageal reflux disease-Health related quality of life (GERD-HRQL) questionnaire, postoperative recurrence, mesh-related complications and patients' overall satisfaction.

RESULTS

A total of 82 patients with hiatal hernia were included in this study. The mean age of the patients was 62.68 ± 15.93 years, mean BMI 24.81 ± 4.05 kg/m2, the average operation time was 128.21 ± 39.20 min. There was statistically significant improvement of GERD symptom postoperative (p<0.05). 72 cases (93.5%) were rated as "Great" on the GERD-HRQL at the 12 months after surgery; 65 cases (84.4%) were rated as "very satisfactory" on the overall satisfaction scale at the 12 months after surgery. 6 patients (7.3%) experienced recurrences, with no mesh-related complications reported during the follow-up.

CONCLUSION

At a mean follow-up of 25.43 ± 10.38 months, the present study showed that laparoscopic hiatal hernia repair with biologic mesh results in low rates of 1-year recurrence and complications and increased patient satisfaction.

Case Report: Total intragastric mesh migration six years after diaphragmatic rupture and hiatal hernia surgery

Background

Mesh implementation to repair the hiatal space is already justified. Nevertheless, the use of this procedure is debated in regard of complications that may occur. Mesh erosion and migration are considered the most serious complications of mesh repairs.

Case presentation

It has not yet been well described in the literature. We describe a case of mesh erosion of stomach, many years later after a prosthetic repair of a diaphragmatic rupture associated to hiatal hernia, is presented here because of its rarity.

Conclusion

Few explanations have been put forward to explain this incident. Could it be due to inflammatory processes, or to the composition of the Meshes? As yet, there is no definitive explanation.

[Mesh suture in the treatment of diaphragmatic hernias]

The paper studies the results of surgical treatment of the first 25 patients with diaphragmatic hernias who underwent laparoscopic surgeries for hiatal hernias using polypropylene mesh sutures using the proprietary method.

MATERIAL AND METHODS

Polypropylene mesh strips were used instead of traditional sutures to seal the crura of the diaphragm in 25 patients. The intervention technique and treatment outcomes are described. The study included 25 patients, 5 males and 20 females, operated on between 2019 and 2024 with a diagnosis of hiatal hernia (HH), aged 38 to 79 years.

RESULTS

The mean surgery duration was 83.4 minutes (50 to 120 minutes), and intraoperative and postoperative complications were not observed. The mean hospital stay was 1.5 days (1 to 4 days). Four patients (16%) had a recurrence of hernia diagnosed using imaging studies, but there were no clinically significant recurrences in all 25 patients. Twenty (80%) patients permanently discontinued proton pump inhibitors (PPIs), and 2 (8%) significantly reduced their dose. Eighteen (72%) patients had complete resolution of their HH-related symptoms; in 4 (16%) patients, these symptoms significantly reduced. All patients were satisfied with the treatment outcomes.

CONCLUSIONS

The use of mesh sutures to seal the crura of the diaphragm supports the concept of pressure distribution and muscle resistance to incision, which is often seen with traditional suture material. In addition, the mesh material stimulates scar tissue growth through the pores of the prosthesis, strengthening the suture line.

Cardiac Tamponade After Video-Assisted Thoracoscopy Surgical Diaphragmatic Plication

Video-assisted thoracoscopy surgical diaphragmatic plication is the standard of care for diaphragmatic eventration. However, it is associated with complications like injuries to the bowel, liver, spleen, and lung parenchyma. We report life-threatening cardiac tamponade after Video-assisted thoracoscopy surgical diaphragmatic plication. The mechanisms contributing to the injury are described as well.

Pericardial tamponade after laparoscopic repair of a giant diaphragmatic hernia

Laparoscopic intraperitoneal onlay mesh repair is favoured for diaphragmatic hernias due to better outcomes. However, fixation devices pose risks, including cardiac tamponade. A man underwent laparoscopic repair for a large diaphragmatic hernia. One week later, he presented with chest discomfort which was initially attributed to postoperative pain. Subsequently, patient represented with worsening of chest pain and tachycardia. CT requested to rule out pulmonary embolism revealed a large pericardial effusion. Urgent drainage via apical approach resolved tamponade. The case highlights the challenges in managing pericardial effusions post-laparoscopy in the presence of diaphragmatic mesh and stresses multidisciplinary collaboration. Literature review highlights risks associated with fixation devices. Suggestions include limiting their use near vital structures. Key learning point of this case report is to raise awareness of cardiac tamponade following diaphragmatic hernia repair. Limited evidence necessitates cautious use of fixation devices, emphasising patient safety.

In vivo comparison of mesh fixation solutions in open and laparoscopic procedures for inguinal hernia repair: A meta-analysis

Background

Abdominal hernia repair surgeries involve the fixation of a surgical mesh to the abdominal wall with different means such as suture, tacks, and glues. Currently, the most effective mesh fixation system is still debated. This review compares outcomes of mesh fixation in different surgical procedures, aiding surgeons in identifying the optimal technique.

Methods

A meta-analysis was conducted according to PRISMA guidelines. Articles published between January 2003 and January 2023 were searched in electronic databases. Randomized controlled trials (RCTs) comparing mesh fixation with cyanoacrylate-based or fibrin glues with classical fixation techniques (sutures, tacks) in open and laparoscopic procedures were included.

Results

17 RCTs were identified; the cumulative study population included 3919 patients and a total of 3976 inguinal hernias. Cyanoacrylate-based and fibrin glues were used in 1639 different defects, suture and tacks in 1912 defects, self-gripping mesh in 404 cases, and no mesh fixation in 21 defects. Glue fixation resulted in lower early postoperative pain, and chronic pain occurred less frequently. The incidence of hematoma was lower with glue fixation than with mechanical fixation. Recurrence rate, seroma formation, operative and hospitalization time showed no significant differences; but significantly, a higher number of people in the glue group returned to work by 15- and 30-days after surgery when compared to the tacker and suture groups in the same time frame.

Conclusion

Cyanoacrylate and fibrin glue may be effective in reducing early and chronic pain and hematoma incidence without increasing the recurrence rate, the seroma formation, or the operative and hospitalization time.

Evidence mapping on how to perform an optimal surgical repair of large hiatal hernias

BACKGROUND

Symptomatic and large hiatal hernia (HH) is a common disorder requiring surgical management. However, there is a lack of systematic, evidence-based recommendations summarizing recent reviews on surgical treatment of symptomatic HH. Therefore, this systematic review aimed to create evidence mapping on the key technical issues of HH repair based on the highest available evidence.

METHODS

A systematic review identified studies on eight key issues of large symptomatic HH repair. The literature was screened for the highest level of evidence (LE from level 1 to 5) according to the Oxford Center for evidence-based medicine's scale. For each topic, only studies of the highest available level of evidence were considered.

RESULTS

Out of the 28.783 studies matching the keyword algorithm, 47 were considered. The following recommendations could be deduced: minimally invasive surgery is the recommended approach (LE 1a); a complete hernia sac dissection should be considered (LE 3b); extensive division of short gastric vessels cannot be recommended; however, limited dissection of the most upper vessels may be helpful for a floppy fundoplication (LE 1a); vagus nerve should be preserved (LE 3b); a dorso-ventral cruroplasty is recommended (LE 1b); routine fundoplication should be considered to prevent postoperative gastroesophageal reflux (LE 2b); posterior partial fundoplication should be favored over other forms of fundoplication (LE 1a); mesh augmentation is indicated in large HH with paraesophageal involvement (LE 1a).

CONCLUSION

The current evidence mapping is a reasonable instrument based on the best evidence available to guide surgeons in determining optimal symptomatic and large HH repair.

Management of complicated diaphragmatic hernia in the acute setting: a WSES position paper

BACKGROUND

Diaphragmatic hernia (DH) presenting acutely can be a potentially life-threatening condition. Its management continues to be debatable.

METHODS

A bibliographic search using major databases was performed using the terms "emergency surgery" "diaphragmatic hernia," "traumatic diaphragmatic rupture" and "congenital diaphragmatic hernia." GRADE methodology was used to evaluate the evidence and give recommendations.

RESULTS

CT scan of the chest and abdomen is the diagnostic gold standard to evaluate complicated DH. Appropriate preoperative assessment and prompt surgical intervention are important for a clinical success. Complicated DH repair is best performed via the use of biological and bioabsorbable meshes which have proven to reduce recurrence. The laparoscopic approach is the preferred technique in hemodynamically stable patients without significant comorbidities because it facilitates early diagnosis of small diaphragmatic injuries from traumatic wounds in the thoraco-abdominal area and reduces postoperative complications. Open surgery should be reserved for situations when skills and equipment for laparoscopy are not available, where exploratory laparotomy is needed, or if the patient is hemodynamically unstable. Damage Control Surgery is an option in the management of critical and unstable patients.

CONCLUSIONS

Complicated diaphragmatic hernia is a rare life-threatening condition. CT scan of the chest and abdomen is the gold standard for diagnosing the diaphragmatic hernia. Laparoscopic repair is the best treatment option for stable patients with complicated diaphragmatic hernias. Open repair is considered necessary in majority of unstable patients in whom Damage Control Surgery can be life-saving.

Cardiac tamponade after robotic hiatal hernia repair from liver sling stitch: Case report of a rare complication and literature review

Introduction and importance

Cardiac tamponade following hiatal hernia repair is a rare and potentially fatal complication most often associated with the use of mechanical fixation devices for hiatal mesh reinforcement. Only three cases have been reported with sutures alone, and none following robotic hiatal surgery.

Case presentation

A 54-year-old patient underwent elective robotic hiatal hernia repair with Toupet fundoplication during which a sling suture was placed to elevate the left lateral segment of liver. No mesh or mechanical fixation devices were used. Eight hours postoperatively, the patient developed hemodynamic instability. Cardiac tamponade was diagnosed on bedside echocardiogram and the patient underwent emergent pericardiocentesis with subsequent stabilization. The remainder of the postoperative course was notable for pericarditis which was treated with aspirin and colchicine.

Clinical discussion

While the use of suture-based liver retraction has the advantages of avoiding an additional port and potential collision between retractor holder and robot arms, it constitutes a novel risk factor for cardiac tamponade. Prompt diagnosis via bedside echocardiography is essential and may facilitate percutaneous rather than operative management.

Conclusion

Suture-based liver retraction in minimally invasive foregut surgery should be used judiciously until further data is available. Surgeons should maintain a high index of suspicion for tamponade in the setting of postoperative hypotension after its use.

•

Hypotension may be a sign of cardiac tamponade after robotic hiatal hernia repair.

•

Slings or other suture techniques that abut the diaphragm may cause tamponade.

•

Prompt diagnosis and drainage can prevent life-threatening hemodynamic compromise.

•

Multidisciplinary care is essential to manage recurrent effusion or pericarditis.

Large hiatus hernia: time for a paradigm shift?

Background

Laparoscopic large hiatal hernia (LHH) repair remains a challenge despite three decades of ongoing attempts at improving surgical outcome. Its rarity and complexity, coupled with suboptimal initial approach that is usually best suited for small symptomatic herniae have contributed to unacceptable higher failure rates.

Results

We have therefore undertaken a systematic appraisal of LHH with a view to clear out our misunderstandings of this entity and to address dogmatic practices that may have contributed to poor outcomes.

Conclusions

First, we propose strict criteria to define nomenclature in LHH and discuss ways of subcategorising them. Next, we discuss preoperative workup strategies, paying particular attention to any relevant often atypical symptoms, indications for surgery, timing of surgery, role of surgery in the elderly and emphasizing the key role of a preoperative CT imaging in evaluating the mediastinum. Some key dissection methods are then discussed with respect to approach to the mediastinal sac, techniques to avoid/deal with pleural breach and rationale to avoid Collis gastroplasty. The issues pertaining to the repair phase are also discussed by evaluating the merits of the cruroplasty, fundoplication types and gastropexy. We end up debating the role of mesh reinforcement and assess the evidence with regards to recurrence, reoperation rate, complications, esophageal dilatation, delayed gastric emptying and mortality. Lastly, we propose a rationale for routine postoperative investigations.

A novel approach for the treatment of Morgagni hernias: robotic transabdominal preperitoneal diaphragmatic hernia repair

PURPOSE

We introduce a novel approach to the surgical repair of Morgagni hernias (MHs) utilizing the robotic transabdominal preperitoneal repair (rTAPP) approach. Borrowed from our previous and robust experience with rTAPP repairs for hernias of the anterior abdominal wall, this technique boasts the benefits of hernia sac reduction, the use of an uncoated mesh in an extraperitoneal plane, and minimal fixation leading to lower postoperative pain relative to other approaches.

METHODS

To evaluate the effectiveness of this novel approach, five consecutive symptomatic Morgagni hernias (MHs) were repaired with the rTAPP approach. The size of the defect, mesh size, length of stay, follow-up imaging, and follow-up complications were documented for comparison.

RESULTS

The size of the MH defects ranged from 4 × 6 cm to 5 × 10 cm. LOS was an average of 1.2 days. Two out of the five patients underwent concomitant repair of a lower abdominal hernias (one Spigelian hernia, and one indirect inguinal hernia). Outpatient follow-up from surgery ranged anywhere from 6 months to 4 years, with most patients receiving follow-up after 1 year. Four out of the five patients received follow-up CT scans to confirm the absence of hernia recurrence. One patient experienced an incisional hernia from the midline 12-mm port site which was repaired 1 year after.

CONCLUSION

We propose a new technique for a minimally invasive strategy to treat these complex hernias utilizing an rTAPP technique resulting in minimal length of stay and a durable result in long-term follow-up. The benefits of repair, which include minimal postoperative pain, minimal length of stay, and cost-effective prosthetic mesh hidden from the visceral contents, are consistent with the author's experience for rTAPP repairs for hernias of the anterior abdominal wall.

When laparoscopic repair is feasible for diaphragmatic hernia in adults? A retrospective study and literature review

BACKGROUND

Diaphragmatic hernia (DH), congenital or traumatic, is uncommon but sometimes can lead to a serious surgical emergency. There are no clinical guidelines or approved recommendations for the management of this condition, and most data are from retrospective, single-institution series. The aim is to analyze the management of the DH at our institution and review the indications for laparoscopic repair.

METHODS

A retrospective serie of patients diagnosed of DH with surgical treatment at our institution between 2009 and 2019. Literature review was carried out to establish the current indications of laparoscopic repair in each type of DH.

RESULTS

Surgery was carried out in 15 patients with DH, 5 congenital and 10 traumatic hernias. Traumatic hernias were classified as acute (n = 2) and chronic (n = 8). 53.4% of all cases (8 patients) required urgent surgery using an abdominal approach (5 open and 3 laparoscopic) and elective surgery was performed in 46.6% of all cases (7 patients) with an abdominal approach (3 open and 4 laparoscopic) and 2 patients with a combined approach. Primary repair was performed in 4 patients (26.6%), closure and mesh reinforcement in 9 cases (60%) and only mesh placement in 2 patients (13.4%). Postoperative morbidity and mortality were 20% and 0%, respectively. No recurrences were detected.

CONCLUSIONS

DH may pose different scenarios which require urgent or elective surgical treatment. Laparoscopic approach may be a first option in elective surgery; and in emergency setting taking into account hemodynamic stability and associated injuries.

Laparoscopic patch repair of a Morgagni hernia in Menkes disease

The association between Morgagni hernia and Menkes disease has not yet been described. Here, we report such a rare association in an 8-year-old boy who presented with subocclusive symptoms. He successfully underwent laparoscopic repair with a patch. The patch was fixed to the anterior abdominal wall by using transfascial sutures with extracorporeal knot tying and to the remaining edges of the diaphragmatic defect by using intracorporeal suturing and spiral tacks. At the 2-year follow-up, the child remained recurrence-free and without gastrointestinal symptoms. The potential relationship between the two conditions and the controversial use of spiral tacks to affix the mesh to the diaphragm are also discussed.

[Mesh Implantation in Anti-Reflux and Hiatal Hernia Surgery - Contra Statement]

In the surgical treatment of gastroesophageal reflux disease and of hiatal hernias, the high rate of recurrence of hiatal hernias is a central problem. Against this background, various, primarily alloplastic, meshes are used to augment suture closure on the esophageal hiatus. Very different results have been reported in the past and the use of meshes in hiatus reconstruction is controversial. In addition to the frequency of recurrences, reports about complications of mesh augmentation are in the foreground. On the basis of several prospective randomised double-blinded comparative studies and meta-analyses (class Ia and Ib evidence), the current data do not show any advantages of mesh-augmented hiatoplasty for the prevention of recurrence of hiatal hernia. At the same time, there exist reports of more long-term postoperative complications, especially dysphagia, after use of meshes for augmentation of hiatus reconstruction. Therefore, routine use of mesh augmentation for hiatus reconstruction is currently not recommended.

Laparoscopic fixation of biological mesh at hiatus with glue and suture during hiatal hernia repair

BACKGROUND

Laparoscopic paraesophageal hernia repair is associated with higher recurrence rate. Mesh is used to reduce the recurrence rate. This retrospective study is to review our experience of biological mesh fixed with suture and medical glue in hiatal hernias repairs.

METHODS

A retrospective chart review was conducted for a consecutive series of patients undergoing laparoscopic hiatal herniorrhaphy between January 2018 and January 2019. After hiatus closure, a piece of biological prosthesis was fixed with medical glue and suture for reinforcement of the crural closure. Clinical outcomes were reviewed, and data were collected regarding operative details, complications, symptoms, and follow-up imaging. Radiological evidence of any size of hiatal hernia was considered to indicate a recurrence.

RESULTS

Thirty-six patients underwent surgery uneventfully without any serious complication. There was no mortality. The follow-up was, on average, 18.4 months, and there was no symptomatic recurrence. There was one anatomical recurrence without any related presentation. The method of mesh fixation with medical glue and suture took 12 min on average, and the handling was fairly easy.

CONCLUSIONS

Biological mesh fixed with suture and medical glue was safe and effective for repairing large hiatal hernias. Of course, a longer follow-up is still needed for determining long-term outcomes.

Laparoscopic repair of hepatic herniation through a ventral incisional hernia: a case report

Background

Ventral incisional hernia is a common problem after abdominal surgery. Most patients with these hernias present with greater omentum and gastrointestinal prolapse. However, hepatic herniation through a ventral incisional hernia is a rare phenomenon that has been seldom reported in the literature. We report the case of a ventral incisional hernia with hepatic herniation treated with laparoscopic repair.

Case presentation

A 68-year-old Japanese women with a history of myocardial resection for hypertrophic cardiomyopathy 1 year earlier was admitted to our hospital with symptoms of vomiting and epigastric pain. Physical examination showed a 4-cm epigastric mass. Abdominal computed tomography revealed left hepatic lobe herniation through the lower edge of a mid-sternal incision. We diagnosed the patient with a ventral incisional hernia with hepatic herniation. The patient underwent laparoscopic hernia repair. During an 18-month follow-up, no recurrence or symptoms have been observed.

Conclusions

To the best of our knowledge, this is the first case report of laparoscopic repair of ventral incisional hernias with hepatic herniation. Laparoscopic repair was useful and suitable for this rare herniation due to its minimally invasive nature and ability to achieve sufficient visibility of the surgical field. Laparoscopic repair could be a potential treatment option for elective surgery for this disease, which is often treated conservatively.

Comparison of a novel preperitoneal sublay repair with traditional onlay repair of morgagni hernia: a tale of two techniques

Morgagni hernia (MH) is a rare diaphragmatic hernia which needs surgical repair. The conventional reconstruction involves reduction of hernia, closure of the defect and placement of an intraperitoneal onlay mesh often using robotic platform for ease of dissection and suturing the mesh (r-IPOM). We propose a novel robotic preperitoneal repair (r-TAPP) of MH in four cases and compare them with conventional r-IPOM technique. Between August 2017 and August 2020 nine patients underwent repair of MH. Five cases underwent repair by r-IPOM (group I). For the other four cases, r-TAPP was used (group II). Among the nine cases, the mean age was 53 years in group I and 55 years in group II, mean defect size was 33 mm in group I and 55 mm in group II. Operative time was longer in group II compared to group I (220 min vs 135 min, p = 0.022). Mean length of hospital stay was 1.3 days in group I compared to group II (4.5 and 4.5 vs 1.3 days, p = 0.03). There was statistically significant difference in reduced post-operative pain and time to return to work in group II compared to group I. There was no difference in complications, 30-day readmissions or recurrence of hernia between the two groups. We conclude that compared to the conventional r-IPOM repair, the r-TAPP technique is associated with less pain, early discharge, and faster return to work, translating into overall cost savings for the hospital.

Mesh-related complications in paraoesophageal repair: a systematic review

BACKGROUND

Paraoesophageal hernias (PEH) have a high recurrence rate, prompting surgeons to consider the use of mesh reinforcement of the hiatus. The risks and benefits of mesh augmentation in PEH repair are debated. Mesh-related complications including migration and erosion are considered in this publication.

DESIGN

A systematic literature review of articles published between 1970 and 2019 in Medline, OVID, Embase, and Springer database was conducted, identifying case reports, case series and observational studies of PEH repair reporting mesh-related complications.

RESULTS

Thirty-five case reports/series of 74 patients and 20 observational studies reporting 75 of 4200 patients with mesh complications have been included. The incidence of mesh-related erosions in this study is 0.035%. PTFE, ePTFE, composite and synthetic meshes were frequently associated with mesh erosion requiring intervention. Complete erosions are often managed endoscopically while partial erosions may require surgery and resection of the oesophagus and/or stomach.

CONCLUSIONS

Mesh-related complication is rare with dysphagia a common presenting feature. Mesh erosion is associated with synthetic mesh more frequently in the reported literature. A mesh registry with long-term longitudinal data would help in understanding the true incidence of mesh-related complications.

Cardiac Tamponade by Tack Fixation of a Hiatal Mesh. Should Tacks Still Be Used in the Diaphragm?

Since the first successful use of mesh in hernia surgery, the development and progress in materials, techniques, and procedures have increased exponentially; consequently, surgeons started to use meshes for hiatal hernia repair to prevent postoperative hernia recurrences and complications. Nonetheless, there are alarming reports in literature concerning cardiac tamponade as an apparently rare complication of hiatal mesh placement, especially when fixation is performed with tacks.

A 50-year-old female diagnosed with gastroesophageal reflux disease undergoes an elective laparoscopic Nissen fundoplication and hiatal hernia repair with tack fixation of the mesh; on the fourth postoperative day she was readmitted with cardiac tamponade diagnosed via echocardiography, and CT scan showed proximity of the tacks to the pericardium. She underwent a failed attempt of ultrasound guided pericardiocentesis (PC), therefore, a pericardial window was performed.

The ideal method for diaphragmatic mesh fixation is still controversial. Some recent articles alert of this potential risk; although the manufacturers contraindicate the use of tacks in the diaphragm, one-third of surgeons prefer this method.

Laparoscopic intraperitoneal onlay mesh (IPOM) repair using n-butyl-2-cyanoacrylate (Liquiband Fix8™) for mesh fixation: learning experience and short-medium term results

AIM

The purpose of this study was to evaluate a novel hernia repair glue fixation device (LiquibandFix8™) in laparoscopic IPOM repair for incisional hernias.

METHODS

All ventral incisional hernia patients requiring laparoscopic IPOM repair were included in the study. A retrospective review of the data was performed.

RESULTS

137 patients underwent 138 laparoscopic IPOM repairs for incisional hernias using n-butyl-2-cyanoacrylate (LiquibandFix8™) for mesh fixation over a 40-month period by a single experienced laparoscopic surgeon. There were 70 males and 67 females, median age 54 years (range 23-80 years). Defects were predominantly midline n = 123/138 (89%) and were closed by transfascial sutures in 126/138 (91%) prior to IPOM repair (IPOM plus). Mesh fixation was successful in all 138 repairs. Synthetic meshes (Symbotex™ [polyester/collagen composite, Medtronic] n = 80, and Dynamesh^® [polypropylene/PVDF composite, FEG Textiltechnik mbH] n = 5) and biologic meshes (Surgimend^® [bovine collagen dermal matrix, Integra] n = 53) were used. Median follow-up was 32 months (range 12-48 months). There were 16 adverse events in 12 patients (9%): conversion to open surgery (inadvertent enterotomy) 2 (1.5%), bladder perforation 1, intraperitoneal bleeding 2, port-site haematoma 2, port site wound infection 1, post-op ileus 2, chest infection 1, seroma 1 (1%), hernia recurrence 3 (2%) and chronic pain 2 (1.5%).

CONCLUSION

This retrospective study shows that mesh fixation in laparoscopic IPOM using cyanoacrylate glue with the Liquiband Fix8™ device is feasible, safe, easy to learn, and is associated with a low risk of seroma, hernia recurrence and chronic pain with short-medium term follow-up.

Hiatal Hernia Presenting with Recurrent Non-ST Elevation Myocardial Infarction and Cardiac Tamponade

Hiatal hernia is a common pathology, particularly among the elderly or obese populations. Occasionally, markedly dilated hernias can impinge on surrounding structures, notably the heart or lung. In such cases, morbidity can be considerable. We present a case of an enlarging hiatal hernia that compressed the heart, leading to recurrent non-ST elevation myocardial infarction with cardiac tamponade. The patient was successfully managed with nasogastric decompression and surgical repair. We recommend that extrapericardial pathology be considered in tamponade patients with concurrent hiatal hernia and that surgery should be considered the definitive treatment modality.

Cyanoacrylate for Safer Mesh Fixation During Laparoscopic Repair of Morgagni Hernia

The surgical repair of all Morgagni hernias is recommended to avoid the risk of strangulation of hernia contents. Mesh augmentation repair can reduce the risk of recurrence, but severe injuries have been reported when tacks are used for mesh fixation to the diaphragm. Cyanoacrylate can provide reliable mesh fixation, and in addition, its application is easy and quick by either the transthoracic or laparoscopic approach. This report describes the main steps of laparoscopic mesh augmentation repair of a Morgagni hernia with a focus on atraumatic mesh fixation with cyanoacrylate, which should prevent the potential complications associated with the use of tacks or sutures.

Anesthetic Management for Paraesophageal Hernia Repair

Paraesophageal hernia repairs are complex surgical cases frequently performed on patients of advanced age with multiple comorbidities, both of which create difficulties in the anesthetic management. Preoperative evaluation is challenging because of overlapping cardiopulmonary symptoms. The patient's symptoms and anatomy lead to an increased aspiration risk and the potential need for a rapid sequence induction. Depending on the surgical approach, lung isolation may be required. Communication with the surgeon is vital throughout the case, especially when placing gastric tube and bougies. Multimodal analgesia should include regional and/or neuraxial techniques, in addition to the standard intravenous and oral pain medications.

Iatrogenic cardiac tamponade as a mortal complication of peri-hiatal surgery. Analysis of 30 published cases

Iatrogenic cardiac tamponade (ICT) is a dreadful complication of peri-hiatal surgery and vast majority occur during a hernia repair. Strikingly, against all warnings, the incidents and related deaths seem to be increasing. The aim of this review is to provide insight on how to prevent and challenge ICT. PubMed search identified 30 distinct ICTs with 10 deaths (33.3%) due to peri-hiatal procedures. Twenty-nine operations were mechanical repairs and laparoscopic anti-reflux surgery was the primary cause (n:18). Graft fixation (n:23) and helical tacks (n:13) were the main offenders. Initial symptom was hypotension affecting 92%. Seven ICTs were only identified at autopsy. All treated patients except one underwent a drainage. Almost all ICTs were caused by injury to the diaphragmatic dome, anterior to hiatus. In conclusion, peri-hiatal surgery-related ICT is extremely fatal. ICT mainly occurs during the repair of a hernia, a benign condition and therefore must be prevented. Graft fixation, around the ante-hiatal diaphragmatic dome must be abandoned. If mesh-augmentation is absolutely necessary, meticulous stitching must be preferred instead of fixators. Persistent hypotension during or following a peri-hiatal operation is an alarming sign of ICT. Increased awareness is mandatory for prevention and survival.

Mid-term safety profile evaluation of Bio-A absorbable synthetic mesh as cruroplasty reinforcement

PURPOSE

The aim of the present paper is to report the results of a single institution series of hiatal hernia repair (HHR) with augmented mesh hiatoplasty focusing on safety and efficacy profile of Bio-A absorbable synthetic mesh.

MATERIALS AND METHODS

A retrospective evaluation of prospectively maintained database showed 120 consecutive patients submitted to HHR reinforced with bio-absorbable synthetic mesh. The study populations included two groups: (A) 92 obese patients-reinforced hiatoplasty concurrent with bariatric procedure; (B) 28 non-obese patients-reinforced hiatoplasty concurrent with antireflux surgery. Symptoms assessment was made with GERD-HRQL and Rome III. The X-ray with barium swallow, the CT scan, in selected cases, and the endoscopy were used as recurrence evaluation and as endoscopic complications assessment. Only patients with a mean follow-up of 12 months were included in this study. A Cox hazard was made to evaluate factors affecting the recurrence.

RESULTS

No case of intra-peri and post-operative (mean follow-up of 41 months) complications mesh related were registered. The dysphagia-rate was 8.7% for Group A and 11% for Group B. 74% of Group A and 61% of Group B patients are actually PPIs free with median GERD-HRQL score of 4 (from 16) and 6 (from 23), respectively (difference pre-post-operative < 0.05). Recurrence rate was 5.4% in Group A and 7.1% in Group B. The Cox hazard analysis showed that the use of more than four stitches for cruroplasty represents a negative factor on recurrence (HR = 8; p < 0.05).

CONCLUSIONS

This is, in our knowledge, the largest report (120 consecutive patients) with mid-term follow-up (41 months of mean FU) on bio-absorbable mesh on the hiatus in obese and non-obese patients. These results supports the use of absorbable mesh for HHR (safe profile-0% of complications rate), showing excellent recurrence rate results and good GERD symptoms control.

Relevance of early CT scan diagnosis of blunt diaphragmatic injury: A retrospective analysis from the Northern French Alps Emergency Network

INTRODUCTION

Diaphragmatic rupture following blunt trauma occurs rarely. Classically described after high-velocity accidents, ruptures are often associated with multiple organ injuries. The diagnosis is sometimes difficult. The goal of this study was to analyze and to discuss the modalities of early radiologic diagnosis and management of these injuries.

PATIENTS AND METHODS

This multicenter retrospective study included patients seen between 2009 and 2017 within the Northern Alpine Emergency Network [REseau Nord Alpin des Urgences (RENAU)]. Clinical, radiologic and surgical data from all patients sustaining blunt diaphragmatic rupture were studied.

RESULTS

Thirty-one patients (18 men and 13 women), median age 44, were included. The principle mechanism of injury was road or traffic accidents for 22 patients. Diaphragmatic rupture occurred on the left side in 23 patients. Diagnosis was delayed in two patients, at 11 days and three months after the initial accident. Chest X-rays were diagnostic in 18 of 29 patients. CT scan was the reference investigation since it was performed in all patients and confirmed the diagnosis in 26 instances. Repair was surgical via a midline laparotomy in 27 patients, via laparoscopy in three, and via thoracoscopy in one. Three patients died.

CONCLUSION

At urgent surgical exploration in the unstable blunt trauma patient, the surgeon should keep in mind the relatively poor diagnostic performance of chest X-rays. Accurate diagnosis relies on routine inspection of the diaphragmatic cupolas. In the stable trauma victim, contrast-enhanced abdomino-thoracic CT with reconstruction can lead to early diagnosis, which allows for repair under optimal conditions, whether by laparotomy, laparoscopy or thoracoscopy, according to local conditions and expertise.
