Giant hiatal hernia

Extracardiac Compression by Gastrointestinal Structures: A Comprehensive Anthology From the Literature

Extrinsic heart compression by gastrointestinal (GI) structures is an often underrecognized finding in clinical practice. It is potentially related to unpredictable clinical conditions, ranging from incidental detection in asymptomatic subjects, to deranging and potentially life-threatening clinical manifestations. However, despite its potential clinical relevance, there is still no comprehensive analysis investigating the surrounding causes, clinical findings, and diagnostic imaging work-up for this patient population. A narrative review with an extensive bibliographic search of the literature was performed using PubMed (MEDLINE), Embase, and Cochrane Central Databases up to December 31, 2023. Despite the broad spectrum of GI etiologies, clinical manifestations, and cardiac chamber involvement scenarios, physicians must be aware of such an uncommon condition, in order to provide timely diagnosis through a comprehensive imaging approach, avoid misleading interpretations, and determine the most appropriate decision-making strategy.

Operative trends and clinical outcomes of open, laparoscopic and robotic approaches to hiatal and paraoesophageal hernias- a study of 1834 patients

Indications for the repair of hiatal and paraesophageal hernias (HH/PEH) have evolved considerably over the past two decades, largely driven by the growing adoption of minimally invasive surgical (MIS) techniques. This shift highlights the need to assess surgical trends and clinical outcomes associated with open (OPEN), laparoscopic (LAP), and robotic (ROBOT) approaches, particularly in cases involving large hernias, with more than 50% exhibiting intrathoracic gastric content. Understanding these trends is crucial as MIS continues to gain prominence in the management of complex cases, including large hernias. The aim of this study is to evaluate key outcomes during the transition from OPEN and LAP to ROBOT-assisted HH/PEH repair at a high-volume surgical center. This retrospective review examined 1,834 patients who underwent consecutive hiatal and paraesophageal hernia (HH/PEH) repairs-open (OPEN, n = 958), laparoscopic (LAP, n = 390), or robotic (ROBOT, n = 486)-between 2000 and 2023 at a large medical center. All patients were prospectively enrolled in an IRB-approved database. The study assessed trends in surgical technique, hernia size, and length of stay (LOS) over time. Additionally, patient demographics, the three most common preoperative symptoms, hernia type and size, surgical course, and clinical outcomes-including LOS, radiographic recurrence (evaluated by esophagrams at 3 and 12 months), reoperation rates, and postoperative symptom improvement-were also evaluated. Robotic surgery was introduced in 2018, with a steady annual increase in its use. The total number of operations performed also saw a significant rise over the study period. Mean hernia size decreased during the study, and the majority of patients (99.1%) presented with symptoms. Robotic surgery (ROBOT) demonstrated significantly superior symptom resolution compared to open surgery (OPEN) (p < 0.01), with this advantage sustained in patients with large hernias (p < 0.01). Additionally, length of stay (LOS) decreased over time. While the overall radiographic recurrence rate (8.6%) and reoperation rate (2.4%) were comparable across surgical techniques, ROBOT showed a higher radiographic recurrence rate for large hernias (18%, p < 0.01) without increase in reoperations. The volume of surgeries for HH/PEH repair has increased over time, driven by expanding surgical indications and advancements in minimally invasive and robotic techniques. Surgical intervention leads to significant improvements in HH/PEH symptoms, with more pronounced benefits seen in larger hernia cases. Minimally invasive surgery (MIS), particularly robotic surgery, demonstrates notable improvements in length of stay (LOS) and at least equivalent clinical outcomes when compared to traditional approaches. While the rates of anatomic recurrence and reoperation remain relatively low, ongoing evaluation-especially of robotic surgery-is essential to further minimize these occurrences.

Long-term durability and temporal pattern of revisional surgery of laparoscopic large hiatal hernia repair

Laparoscopic repair is the preferred surgical treatment for symptomatic Large Hiatal Hernia (LHH). However, data on long-term outcomes are limited. This study aims to evaluate the 20-year follow-up results of laparoscopic LHH repair in a high-volume experienced tertiary center. Retrospective analysis of patients who underwent elective laparoscopic LHH repair between 1992 and 2008. Preoperative and perioperative data were collected. The primary endpoint was the long-term reoperation rate. Survival analyses were calculated according to the Kaplan-Meier method and compared with the log-rank test. A Cox proportional hazard model was used to investigate predictive factors of the need for revisional surgery. A total of 176 patients were included. All the procedures were performed laparoscopically, and in 5 cases (3.0%) with a robot-assisted approach. Mesh-augmented cruroplasty was performed in 26 patients (15.8%). A fundoplication was added in all patients: Nissen in 158 (89.8%), Toupet in 5 (2.8%), and Collis-Nissen in 13 (7.4%). Postoperative mean follow-up was 224.6 ± 83.3 months. Clinically significant hiatal hernia recurrence occurred in 27 (16.2%), and 18 patients (10.2%) underwent surgical revision. The median time-to-redo was 12 months (IQR 6-42 months). Overall durability without revisional surgery at 20-year follow-up was 90%. The rate of revisional surgery after LHH repair is low and is generally required within 12 months from primary surgery. Our results highlight the long-lasting effects of LHH repair at 20-year follow-up.

Voluminous hiatal hernias - the role of robotic surgery

Robotic surgery has become increasingly prevalent in UGI surgery over the last decade, particularly for treating hiatal hernias. Voluminous hiatal hernias, defined as the herniation of 30-50 % of the stomach into the thorax, often require surgical intervention due to associated dysphagia and potential severe complications. Given the challenges of repairing voluminous hiatal hernias, especially in elderly and fragile patients, the surgical technique should be optimal. Robotic surgery affords excellent visualization, allowing high mediastinal dissection and precise hiatus reconstruction. Despite the clear technical advantages, it remains to be demonstrated if the robotic approach matches the outcomes of conventional laparoscopic techniques. We review here the fundamentals of hiatal hernia surgery and describe our surgical technique using the da Vinci Xi robot to operate voluminous hiatal hernias. Additionally, we performed a systematic research analysis and selected recent publications focusing on robotic surgery for voluminous hiatal hernias. Recent studies report comparable complication rates, recurrence, and hospital stay lengths between robotic and laparoscopy surgery. Initial robotic procedures had longer operative times, which decreased with surgeon experience. Most of the studies were observational and retrospective, reporting the experience of a single center. Robotic surgery appears to be a viable option with similar complications rates to laparoscopic surgery under optimized conditions. Current literature supports the broader adoption of robotic surgery for voluminous hiatal hernias. However, prospective randomized studies are needed to further validate its use.

Outcomes after revisional surgery for paraesophageal hernias at a high-volume tertiary care center

BACKGROUND

Although recurrences after repair of giant paraesophageal hernias (PEH) are common, revisional procedures are challenging and associated with higher complication rates than primary repair. Therefore, repair of recurrent PEH is often avoided except in symptomatic patients. Data describing operative outcomes in these infrequent cases is lacking. Therefore, this study aimed to report and compare peri-operative outcomes of revisional PEH repair to similar patients undergoing primary surgery.

METHODS

A single-institution, retrospective cohort study was conducted on all adult patients undergoing primary repair of Type II-IV PEH and any revisional surgery for recurrent hiatal hernia after previous primary PEH repair (2012-2019). Patient and operative characteristics and post-operative outcomes were extracted from medical records. Patients were grouped into revisional (rPEH) and primary repair (pPEH). Coarsened exact matching was performed to create balanced cohorts.

RESULTS

A total of 347 cases were identified. The matched cohort included 234 patients (rPEH: 46, pPEH: 188). Patient sex and comorbidities were well balanced, while those who underwent revisions were younger (64 ± 13 vs. 69 ± 11 years; p = 0.01). Median time between primary and rPEH was 40[17-121] months. Incidence of emergency repair were similar among groups (rPEH: 9(15%), pPEH: 14(8%); p = 0.10). All revisional cases commenced laparoscopically with 7(15%) requiring conversion to open. The conversion rate was higher for rPEH than primary surgery (7(15%) vs. 3(2%); p < 0.01), with the most common reasons being adhesions and gastric fundus injury. Intra-operative complications occurred in 12(26%) revisional cases, of which 58% were gastric fundus injuries. Median length of stay was longer for rPEH than pPEH (2[1-5] vs. 1[1-2] day; p = 0.02). Incidence of severe complications (rPEH: 5(11%), pPEH: 11(6%); p = 0.23) and reoperations (rPEH: 2(4%), pPEH: 7(4%); p = 0.84) were similar between groups. There were no peri-operative deaths.

CONCLUSION

In a high-volume tertiary care center, repair of recurrent giant paraesophageal hernias can be performed successfully laparoscopically in the majority of cases with acceptable morbidity and peri-operative outcomes in comparison to primary surgery.

Acute Pericarditis as a Complication of Hiatal Hernia Perforation

Acute pericarditis is a serious and potentially fatal disease in which a diagnostic workup is not always straightforward. Hiatal hernia, on the other hand, is often asymptomatic and can be easily diagnosed if symptomatic. In advanced forms of hiatal hernia, oppression of intrathoracic organs and heart failure can occur. In uncommon cases, the large intestine can also be translocated into the chest cavity, and very rarely, it can be perforated with the development of mediastinitis and/or pericarditis. We report the case of a 74-year-old female with a 1.5-month history of chest pain with elevated inflammatory markers. This patient was empirically treated with antibiotics for suspected pneumonia. After a few weeks, due to a worsening of the patient's condition, an echocardiogram and then a CT of the chest were performed, showing a large hiatal hernia and a very probable purulent pericarditis, necessitating a surgical exploration. A cardiac surgeon found stercoral contents in the pericardium, with a fistula at the apex of the heart. The operation continued with an exploration of the abdominal cavity; the general surgeon returned the massive hiatal hernia to the abdomen, the contents of which were the stomach and transverse colon. An extensive perforation in the transverse colon was found. Lavage, drainage, and resection of the affected part of the intestine were performed, and a permanent (terminal) colostomy was constructed. The patient was in severe septic shock with multiorgan failure and died 10 hours after surgery despite maximal therapy. This case highlights the importance of interdisciplinary cooperation and the importance of considering the possible fistula in the co-occurrence of hiatal hernia and pericarditis.

[Surgical strategy for hiatal hernias]

The indications for surgical treatment of hiatus hernias differentiate between type I and types II, III and IV hernias. The indications for a type I hernia should include a proven reflux disease but the indications for surgical treatment of types II, III and IV hernias are mandatory due to the symptoms with problems in the passage of food and due to the sometimes very severe possible complications. The primary aims of surgery are the repositioning of the herniated contents and a hiatoplasty, which includes a surgical narrowing of the esophageal hiatus by suture implantation. In addition, depending on the clinical situation other procedures, such as hernia sac removal, mesh implantation, gastropexy and fundoplication can be considered. There are various approaches to the repair, all of which have individual advantages and disadvantages. An adaptation to the specific needs situation of the patient and the expertise of the surgeon is therefore essential.

Could "Low Quality of Life" Rather Than "Significant Symptoms" Be Better Criteria for the Selection of Patients for the Repair of a Giant Hiatus Hernia?

Purpose Giant hiatus hernia (GHH) repair is undertaken electively in symptomatic patients, to prevent complications such as gastric volvulus and subsequent mortality. Advances in laparoscopy and perioperative care have reduced the risk of GHH repair, and improvement in quality of life (QoL) has become an important outcome measure. In our unit, we have been assessing QoL in all the operated as well as non-operated patients with GHH, using the "Quality of Life in Reflux and Dyspepsia" (QOLRAD) questionnaire. We sought to evaluate differences in QoL between patients who were managed conservatively for GHH and those who underwent GHH repair over a two-year period. Methods All patients seen in the Upper Gastrointestinal Tertiary Unit in Lancashire Teaching Hospitals NHS Trust with GHH between January 2015 and December 2022 were identified from a prospectively kept database. QOLRAD scores were analyzed and compared between conservatively and operatively managed patients using the Mann-Whitney U test. Demographic and operative outcome data were also collected. Results Eighty-seven patients with GHH were included. QoL of 51 patients improved significantly after elective surgery. Five out of 36 patients, who were initially treated conservatively, elected to have repair during their follow-up period. These 5 Patients had a lower initial QOLRAD score in comparison to those whose management remained conservative (2.72 vs 5.05, Mann Whitney U test p=0.034), and their QOLRAD scores also improved significantly after the operation. QOLRAD scores in conservatively managed patients remained stable over a two-year follow-up period. Conclusion Objectively calculated low QoL may be a more useful tool than subjective symptoms in selecting patients for elective repair of GHH.

Hiatal Hernia of Stomach and Lesser Omentum in a Cadaver: Is It a Type III or IV?

Hiatal hernias, protrusions of abdominal viscera through the esophageal hiatus, are classified into four types. Types I and II involve ascent of the stomach without affecting the gastroesophageal junction. Types III and IV involve the gastroesophageal junction. Type IV specifically may have stomach as well as other abdominal organ involvement, such as pancreas or omentum. Among these types, type IV is the most complex and rare form, accounting for only 0.1% of all cases of hiatal hernias. This report presents a case of a type IV hiatal hernia involving the lesser omentum and a significant portion of the stomach in an 86-year-old male cadaver with a history of mediastinal surgery. To our knowledge, this presentation in a cadaver has not previously been reported in the literature.  This case highlights classification inconsistencies in the literature, particularly regarding type IV hiatal hernias. It is unclear given the current classification system, whether this presentation would be considered a type III or type IV hiatal hernia as it fits both criteria and there are several interpretations of the criteria of a type IV hiatal hernia. Inconsistencies in the classification system may impede standardization of care. This report highlights the need for a more precise classification system that better accounts for anatomical changes and clinical presentation.

Adjuvant Botulinum Toxin Type A on the Management of Giant Hiatal Hernia: A Case Report

The management of giant hiatal hernias (HHs) remains challenging and is associated with a high risk of recurrence. Currently, several strategies are used to reduce recurrence, and a newly proposed trend is the administration of adjuvant botulinum toxin type A (BTX), a procedure already performed in complex ventral hernias. Here, we present a case of a 63-year-old man with a giant paraesophageal HH type IV containing the entire stomach and transverse colon with loss of domain, who underwent adjuvant BTX and subsequently laparoscopic hiatoplasty with a biological mesh with partial fundoplication. At six months' follow-up, the patient reported a significant improvement in the quality of life without dysphagia or gastroesophageal reflux and with a good respiratory function. A control computed tomography was performed, which documented a partial recurrence of HH, completely asymptomatic. This clinical case showed the successful treatment of a giant HH using adjuvant BTX injection to increase abdominal wall compliance as had already been described in the treatment of complex ventral hernia. Thus, the use of BTX is a promising strategy for selected cases of giant HHs mainly if there is a loss of domain; however, more case series and controlled trials are needed to show the reproducibility of the benefit of this strategy.

Hiatal Hernia Repair: Can We Predict the Need for Mesh?

Introduction: The use of mesh for paraesophageal hernia repair is controversial due to concerns about long-term complications. This study aimed to investigate whether preoperative imaging characteristics of diaphragmatic hernia could predict the need for mesh repair. Methods: The records of all patients who underwent laparoscopic diaphragmatic hernia repair between September 2015 and September 2022 were reviewed. Patients' preoperative computerized tomography (CT) imaging was reviewed and was correlated with mesh repair. Results: A total of 53 patients were included in the study. Volumetric measurements were obtained from preoperative CT scans to assess hiatal defect area (HDA) and hernia sac volume (HSV). Mesh repair was required in 43.4% of cases, all among types II-IV. The mesh repair group had a higher mean hiatal neck height (50.8 ± 16.35 versus 43.22 ± 17.08 mm, P < .032) and higher HSV (708.53 ± 577.6 versus 346.866 ± 321.65 cm3, P < .003). There was also a borderline difference in HDA mean values (23.78 ± 17.22 versus 16.8 ± 10.41 cm2, P < .059). Conclusions: Preoperative HSV on CT scans can be a valuable predictor for the need for mesh repair during hiatal hernia surgery, aiding surgical planning and decision-making. Further research is needed to validate these findings and optimize hernia repair outcomes.

[Antireflux laparoscopic intervention]

OBJECTIVE

To study the safety and efficacy of laparoscopic fundoplication and hiatal hernia repair for gastroesophageal reflux disease following hiatal hernia.

MATERIAL AND METHODS

We retrospectively analyzed 56 patients with gastroesophageal reflux disease and hiatal hernia .They underwent laparoscopic fundoplication and hiatal hernia repair between January 2020 and January 2023.

RESULTS

All surgeries were successful without conversion to open surgery. Surgery time was 56-180 min (mean 68.4±3.6), blood loss 30-200 ml (mean 40.3±5.6). No mortality and severe complications occurred. All patients were followed-up for 6-24 months. The GERD-Q and De Meester scores were significantly lower after 6 months compared to baseline values (p <0.05), and resting pressure was lower. Tone of lower esophageal sphincter was significantly higher compared to preoperative level (p <0.05). In 1-2 years after surgery, symptoms completely disappeared in 48 patients and significantly improved in 6 patients. Two patients had no improvement. Contrast-enhanced examination found no recurrent hiatal hernia and digestive tract obstruction.

CONCLUSION. L

Aparoscopic fundoplication and hiatal hernia repair is safe and effective for gastroesophageal reflux disease with hiatal hernia.

Upside-down stomach in paraesophageal hernia: A case report

RATIONALE

Paraesophageal hernias, accounting for a mere 5% to 10% of all hiatal hernias, occasionally present an exceedingly uncommon yet gravely consequential complication characterized by the inversion of the stomach. Delving into the clinical manifestations and optimal therapeutic approaches for patients afflicted by this condition merits substantial exploration.

PATIENT CONCERNS

A 60-year-old man was referred to our hospital with acute onset of severe epigastric pain, abdominal distension, and vomiting. A chest radiograph unveiled an elevated left diaphragmatic dome accompanied by a pronounced rightward shift of the mediastinum. Subsequent abdominal computed tomography imaging delineated the migration of the stomach, spleen, and colon into the left hemithorax, facilitated by a significant diaphragmatic defect.

DIAGNOSES

The diagnosis of a giant paraesophageal hernia with complete gastric inversion was established through a comprehensive evaluation of the patient's clinical manifestations and imaging findings.

INTERVENTIONS

Surgical intervention was performed on the patient. During the procedure, a left diaphragmatic defect measuring approximately 10 × 8 cm was identified and meticulously repositioned, followed by the repair of the diaphragmatic hernia. The herniated contents comprised the pancreas, stomach, spleen, a segment of the colon, and a portion of the greater omentum.

OUTCOMES

The patient experienced a smooth postoperative recuperation and was discharged 12 days following the surgical procedure. Subsequently, during a 7-month follow-up period, the patient continued to exhibit favorable progress and recovery.

LESSONS

Paraesophageal hernias are rare, and the presence of an inverted stomach in a giant paraesophageal hernia is exceptionally uncommon. Clinical presentation lacks distinct features and can lead to misdiagnosis. This case emphasizes the importance of timely surgical intervention guided by imaging, offering valuable clinical insights.

Recurrence in Paraesophageal Hernia: Patient Factors and Composite Surgical Repair in 862 Cases

BACKGROUND

Repair of giant paraesophageal hernia (PEH) is associated with a considerable hernia recurrence rate by objective measures. This study analyzed a large series of laparoscopic giant PEH repair to determine factors associated with anatomical recurrence.

METHOD

Data was extracted from a single-surgeon prospective database of laparoscopic repair of giant PEH from 1991 to 2021. Upper endoscopy was performed within 12 months postoperatively and selectively thereafter. Any supra-diaphragmatic stomach was defined as anatomical recurrence. Patient and hernia characteristics and technical operative factors, including "composite repair" (360° fundoplication with esophagopexy and cardiopexy to right crus), were evaluated with univariate and multivariate analysis.

RESULTS

Laparoscopic primary repair was performed in 862 patients. The anatomical recurrence rate was 27.3% with median follow-up of 33 months (IQR 16, 68). Recurrence was symptomatic in 45% of cases and 29% of these underwent a revision operation. Hernia recurrence was associated with younger age, adversely affected quality of life, and were associated with non-composite repair. Multivariate analysis identified age < 70 years, presence of Barrett's esophagus, absence of "composite repair", and hiatus closure under tension as independent factors associated with recurrence (HR 1.27, 95%CI 0.88-1.82, p = 0.01; HR 1.58, 95%CI 1.12-2.23, p = 0.009; HR 1.72, 95%CI 1.2-2.44, p = 0.002; HR 2.05, 95%CI 1.33-3.17, p = 0.001, respectively).

CONCLUSION

Repair of giant PEH is associated with substantial anatomical recurrence associated with patient and technique factors. Patient factors included age < 70 years, Barrett's esophagus, and hiatus tension. "Composite repair" was associated with lower recurrence rate.

Impact of laparoscopic repair on type III/IV giant paraesophageal hernias: a single-center experience

PURPOSE

Giant paraesophageal hernia (GPEH) is a challenging problem for surgeons because of its high recurrence rate. This study was conducted to compare the outcomes in type IV vs. type III GPEHs after laparoscopic repair. Other outcomes included peri-operative morbidity and long-term quality of life.

METHODS

A retrospective analysis of 130 GPEH patients in a period between 2010 and 2019 underwent a tailored laparoscopic repair in our tertiary center with a minimum follow-up of 48 months. Operative steps included hernial sac excision, crural repair, relaxing incisions, and mesh cruroplasty with special indications.

RESULTS

The study enrolled 90 patients with type III and 40 patients with type IV GPEH. Type IV GPEH patients were older, more fragile, and scored worse on ASA classification, aside from having a more challenging surgical technique (wider crura, weaker muscles, increased need for release incisions, and mesh cruroplasty).Type IV GPEHs had a prolonged operative durations, and a higher conversion rate. Additionally, the same group showed increased morbidity, mortality, and re-operation rates. With a mean follow-up of 65 months (range 48-150 months), the incidence of recurrence was 20.7%, with an increased incidence in type IV GPEH (37.5% vs. 13.33% in type III GPEH). Type IV GPEH, low pre-operative albumin, larger crural defect, and low surgeon experience were significant risk factors for recurrence after laparoscopic repair of GPEH.

CONCLUSION

Type IV GPEH has a higher peri-operative morbidity and recurrence rate; so, a more tailored laparoscopic repair with a high surgeon experience is needed.

A Higher Manometric Esophageal Length to Height Ratio in Achalasia Explains the Lower Prevalence of Hiatal Hernia

Background/Aims

The evidence suggests that a shorter esophageal length (EL) in gastroesophageal reflux disease (GERD) patients is associated with the presence of hiatal hernia (HH). However, there are no reports of this association in patients with achalasia. The aim is to (1) determine the prevalence of hiatal hernia in achalasia patients, (2) compare achalasia EL with GERD patients and healthy volunteers (HV), (3) measure achalasia manometric esophageal length to height (MELH) ratio, and (4) determine if there are differences in symptoms between patients with and without hiatal hernia.

Methods

This retrospective and cross-sectional study consist of 87 pre-surgical achalasia patients, 22 GERD patients, and 30 HV. High-resolution manometry (HRM), barium swallow, and upper endoscopy were performed to diagnose HH. The EL and MELH ratio were measured by HRM. Symptoms were assessed with Eckardt, Eating Assessment Tool, and GERD-health-related quality of life questionnaires.

Results

The HH in GERD's prevalence was 73% vs 3% in achalasia patients (P < 0.001). Achalasia patients had a longer esophagus and a higher MELH ratio than HV and GERD patients (P < 0.001). GERD patients had a lower MELH ratio than HV (P < 0.05). EAT-10 (P < 0.0001) and Eckardt (P < 0.05) scores were higher in achalasia without HH vs HH.

Conclusions

The prevalence of HH in achalasia is significantly lower than in GERD. The longer EL and the higher MELH ratio in achalasia could explain the lower prevalence of HH. Despite the low prevalence of HH in achalasia patients, the surgeon should be encouraged not to rule out HH since the risk of postoperative reflux may increase if this condition is not identified and corrected.

Research protocol for the Paraesophageal hernia symptom tool, a prospective multi-center cohort study to identify the need and threshold for surgery and assess the symptom response to surgery

Large hiatus hernias with a significant paraesophageal component (types II-IV) have a range of insidious symptoms. Management of symptomatic hernias includes conservative treatment or surgery. Currently, there is no paraesophageal hernia disease-specific symptom questionnaire. As a result, many clinicians rely on the health-related quality of life questionnaires designed for gastro-esophageal reflux disease (GORD) to assess patients with hiatal hernias pre- and postoperatively. In view of this, a paraesophageal hernia symptom tool (POST) was designed. This POST questionnaire now requires validation and assessment of clinical utility. Twenty-one international sites will recruit patients with paraesophageal hernias to complete a series of questionnaires over a five-year period. There will be two cohorts of patients-patients with paraesophageal hernias undergoing surgery and patients managed conservatively. Patients are required to complete a validated GORD-HRQL, POST questionnaire, and satisfaction questionnaire preoperatively. Surgical cohorts will also complete questionnaires postoperatively at 4-6 weeks, 6 months, 12 months, and then annually for a total of 5 years. Conservatively managed patients will repeat questionnaires at 1 year. The first set of results will be released after 1 year with complete data published after a 5-year follow-up. The main results of the study will be patient's acceptance of the POST tool, clinical utility of the tool, assessment of the threshold for surgery, and patient symptom response to surgery. The study will validate the POST questionnaire and identify the relevance of the questionnaire in routine management of paraesophageal hernias.

Laparoscopic hiatal hernia repair for treating patients with massive hiatal hernia and iron-deficiency anaemia

BACKGROUND

Massive hiatal hernias may result in extraoesophageal symptoms, including iron-deficiency anaemia. However, the role played by hiatal hernias in iron-deficiency anaemia is not clearly understood. We examined the prevalence of anaemia in patients with massive hiatal hernias and the frequency of anaemia resolution after laparoscopic hiatal hernia repair at long term follow-up.

METHODS

Patients who underwent laparoscopic hiatal hernia repair from June 2008 to June 2019 were enrolled in this study. We collected the patients' demographic and clinical data from their medical records, and compared the pre-surgical and post-surgical findings (at 1 week and 3 months post-surgery). All patients with adequate documentation underwent post-surgical follow-up to evaluate improvements in clinical symptoms and signs.

RESULTS

A total of 126 patients with massive hiatal hernias underwent laparoscopic hiatal hernia repair. Of these, 35 (27.8%) had iron-deficiency anaemia. Anaemia was resolution in all the patients and they had significantly reduced GERD-Q scores at 3 months postoperatively (P<0.01) .The mean follow-up period was 60 months. Iron-deficiency anaemia resolution after hiatal hernia repair was achieved in 93.9% of the patients.

CONCLUSION

Anaemia is common in patients with massive hiatal hernias, and most of our patients were symptomatic because of their anaemia. Moreover, in patients with massive hiatal hernias, iron-deficiency anaemia resolution is likely after laparoscopic hiatal hernia repair.

Dyspnoea improves following composite repair of giant paraoesophageal hernia

INTRODUCTION

Paraoesophageal hernias (PEH) are often symptomatic and can lead to life-threatening complications such as volvulus and ischaemia. Dyspnoea is one of the most prevalent symptoms of giant hiatus herniae. The primary outcome of this study is resolution of dyspnoea following composite repair of giant paraoesophageal hernia. Secondary outcomes include complications of surgery, hernia recurrence rates and effect of recurrence on dyspnoea.

METHODS

Data were extracted from a prospectively maintained single-surgeon database containing records of all patients undergoing composite repair of paraoesophageal hernia. Patients presenting with dyspnoea who underwent composite laparoscopic repair of giant (>30% of stomach above diaphragm) paraoesophageal hernia between March 2009 and December 2015 were included.

RESULTS

Inclusion criteria were met by 154 patients. The mean age at time of surgery was 71.2 years (range 49-93, SD 9.66) with an average BMI of 28 (range 19-38kg/m2, SD 4.1). On average hernia contained 64% of stomach (range 30-100%, SD 20.2). One procedure was converted to laparotomy. Surgery resulted in near complete resolution of dyspnoea (2.6% postoperatively, p<0.001). Recurrence rate was 24% and was not associated with persistent dyspnoea. There was one death and two significant complications.

CONCLUSION

Dyspnoea resolves following laparoscopic repair of giant paraoesophageal hernia. The presence of dyspnoea in patients with known large paraoesophageal hernia should be regarded as an indication for referral to a surgical service with expertise in hiatal hernia management.

The impact of frailty on outcomes following laparoscopic repair of 'giant' paraesophageal hernias

BACKGROUND

Frailty is a measure of physiologic reserve and correlates with surgical outcomes in the elderly. Patients who present with giant paraesophageal hernias (PEH) are typically older than 65. We defined 'giant' as a PEH with 50% or more of the stomach in the chest. We hypothesized that frailty correlates with 30-day complications, length of stay, and discharge destination following laparoscopic giant PEH repair.

METHODS

Patients older than 65 to undergo primary laparoscopic repair of a giant PEH at a single academic medical center between 2015 and 2022 were included. Hernia size was determined by preoperative imaging. Frailty was assessed clinically prior to surgery using the modified Frailty Index (mFI), an 11-item instrument that counts clinical deficits associated with frailty. A score ≥ 3 was considered frail. A major complication was a Clavien grade IIIB or higher.

RESULTS

Of the 162 patients included in the study, mean age was 74.4 ± 7.2, and 66% of patients were female (n = 128). The mFI was ≥ 3 in 37 patients (22.8%). Frail patients were older (78 ± 7.9 vs. 73 ± 6.6 years, p = 0.02). There was no difference in overall complication rate (40.5% vs. 29.6%, p = 0.22) or major complication rate (8.1% vs. 4.8%, p = 0.20) between frail and non-frail patients. Functionally impaired patients (METS < 4) were more likely to develop a major complication (17.9% vs. 3.0%, p < 0.01). Average length of stay was 2.4 days, and frail patients experienced a longer mean hospital stay (2.5 ± 0.2 vs. 2.3 ± 1.8, p = 0.03). Frail patients were more likely to be discharged to a destination other than home.

CONCLUSION

Increased frailty as assessed by the mFI is correlated with length of stay and discharge destination following laparoscopic repair of giant PEH in patients > 65. Complication rates were comparable for both frail and non-frail cohorts.

Percentage of intrathoracic stomach predicts operative and post-operative morbidity, persistent reflux and PPI requirement following laparoscopic hiatus hernia repair and fundoplication

PURPOSE

Large hiatus hernias are relatively common and can be associated with adverse symptoms and serious complications. Operative repair is indicated in this patient group for symptom management and the prevention of morbidity. This study aimed to identify predictors of poor outcomes following laparoscopic hiatus hernia repair and fundoplication (LHHRaF) to aid in counselling potential surgical candidates.

METHODOLOGY

A retrospective analysis was performed from a prospectively maintained, multicentre database of patients who underwent LHHRaF between 2014 and 2020. Revision procedures were excluded. Hernia size was defined as the intraoperative percentage of intrathoracic stomach, estimated by the surgeon to the nearest 10%. Predictors of outcomes were determined using a prespecified multivariate logistic regression model.

RESULTS

625 patients underwent LHHRaF between 2014 and 2020 with 443 patients included. Median age was 65 years, 62.9% were female and 42.7% of patients had ≥ 50% intrathoracic stomach. In a multivariate regression model, intrathoracic stomach percentage was predictive of operative complications (P = 0.014, OR 1.05), post-operative complications (P = 0.026, OR 1.01) and higher comprehensive complication index score (P = 0.023, OR 1.04). At 12 months it was predictive of failure to improve symptomatic reflux (P = 0.008, OR 1.02) and persistent PPI requirement (P = 0.047, OR 1.02). Operative duration and blood loss were predicted by BMI (P = 0.004 and < 0.001), Type III/IV hernias (P = 0.045 and P = 0.005) and intrathoracic stomach percentage (P = 0.009 and P < 0.001). Post-operative length of stay was predicted by age (P < 0.001) and emergency presentation (P = 0.003).

CONCLUSION

In a multivariate regression model, intrathoracic stomach percentage was predictive of operative and post-operative morbidity, PPI use, and failure to improve reflux symptoms at 12 months.

Surgical treatment of large and complicated hiatal hernias with the new resorbable mesh with hydrogel barrier (Phasix™ ST): a preliminary study

Evaluation of the efficacy and safety of the new monofilament fully resorbable mesh with hydrogel barrier (Phasix™ ST), for large and complex hiatal hernia repair. Between December 2017 and December 2020, 60 patients with large or complicated hiatal hernia were treated (40 robotic and 20 laparoscopic procedures). The mesh was placed after primary closure of the hiatal defect, in an onlay fashion around the esophagus, followed by 360^o fundoplication. Follow-up at 3, 6, 12, 18, 24 months from intervention included clinical evaluation and upper GI endoscopy. In cases of recurrence, radiologic survey and manometry were utilized. There were no conversions to open repair or significant postoperative incidents. Over a median follow-up of 21 months (range 3-36), no recurrences or mesh related complications were observed. From our early experience, Phasix™ ST mesh seems to be safe and effective for the reinforcement of crural defects in large and complex hiatal hernia.

Minimally Invasive Abdominal Repair of a Giant Paraesophageal Hiatal Hernia with Occupation of the Right Thorax in a 53-Year-Old Man

Paraesophageal giant hiatal hernia is a rare condition associated with serious complications if not treated surgically. There are no reports of the minimally invasive abdominal repair of a giant hiatal hernia of the stomach almost entirely occupying the right thoracic cavity. The most common clinical presentation includes pathological gastroesophageal reflux, dysphagia, chest pain, or respiratory symptoms such as chronic cough or dyspnoea. Chest computed tomography, upper gastrointestinal endoscopy, and high-resolution oesophageal manometry are used to indicate the best treatment. This article reports the minimally invasive abdominal repair of a case of paraesophageal giant hiatal hernia occupying the right thoracic cavity.

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.

Laparoscopic fundoplication for para-oesophageal hernia repair improves respiratory function in patients with dyspnoea: a prospective cohort study

Background

Dyspnoea in patients with a para-oesophageal hernia (PEH) occurs in 7% to 32% of cases and is very disabling, especially in elderly patients, and its origin is not well defined. The present study aims to assess the impact of PEH repair on dyspnoea and respiratory function.

Methods

From January 2019 to May 2021, all consecutive patients scheduled for PEH repair presenting with a modified Medical Research Council (mMRC) score ≥ 2 for dyspnoea were included. Before and 2 months after surgery, dyspnoea was assessed by both the dyspnoea visual analogue scale (DVAS) and the mMRC scale, as well as pulmonary function tests (PFTs) by plethysmography.

Results

All 43 patients that were included had pre- and postoperative dyspnoea assessments and PFTs. Median age was 70 years (range 63–73.5 years), 37 (86%) participants were women, median percentage of the intrathoracic stomach was 59.9% (range 44.2–83.0%), and median length of hospital stay was 3 days (range 3–4 days). After surgery, the DVAS decreased statistically significant (5.6 [4.7–6.7] vs. 3.0 [2.3–4.4], p < 0.001), and 37 (86%) patients had a clinically significant decrease in mMRC score. Absolute forced expiratory volume in one second (FEV1), total lung capacity, and forced vital capacity also statistically significantly increased after surgery by an average of 11.2% (SD 17.9), 5.0% (SD 13.9), and 10.7% (SD 14.6), respectively. Furthermore, from the subgroup analysis, it was identified that patients with a lower preoperative FEV1 were more likely to have improvement in it after surgery. No correlation was found between improvement in dyspnoea and FEV1. There was no correlation between the percentage of intrathoracic stomach and dyspnoea or improvement in PFT parameters.

Conclusion

PEH repair improves dyspnoea and FEV1 in a statistically significant manner in a population of patients presenting with dyspnoea. Patients with a low preoperative FEV1 are more likely to have improvement in it after surgery.

A Breathtaking Hernia: A Giant Hiatal Hernia Masquerading as Poorly Controlled Asthma

A 93-year-old female presented with persistent shortness of breath and wheezing since the consumption of a meal. Her past medical history is significant for a clinical diagnosis of asthma at the age of 88 years, without pulmonary function testing, complicated by several prior visits to the emergency department (ED) for recurrent exacerbations. Multiple bronchodilators in the ED provided only minimal improvement in her symptoms. Chest imaging eventually revealed a giant, fluid-filled hiatal hernia exhibiting a compressive effect on the posterior aspect of the left atrium. The etiology of the patient's airway bronchoconstriction was likely multifactorial. We hypothesize that the extrinsic, dynamic compression of the bronchial tree by the peristaltic motion of the hiatal hernia, microaspiration from gastroesophageal reflux, and peribronchial edema from left atrial compression accounted for our patient's unique presentation. An outpatient methacholine challenge test eventually excluded bronchial asthma. Although she was considered a poor surgical candidate, she has had no further recurrences of her symptoms with counseling on conservative lifestyle changes. This case serves to highlight the heterogeneity in presentations of hiatal hernias, particularly in elderly females. Furthermore, it remains prudent to maintain a broad differential for wheezing, as evidenced by our patient who was previously managed for a number of years as poorly controlled asthma.

Laparoscopic repair of giant hiatal hernia for elderly patients

Background

Giant hiatal hernias are more common in older patients and can significantly reduce their quality of life. However, open surgery for patients of advanced age is thought to be associated with high morbidity and mortality. The aim of this retrospective study was to evaluate the safety of laparoscopic giant hiatal hernia repair for elderly patients as compared to younger patients.

Methods

From January 2015 to January 2020, 152 consecutive patients underwent laparoscopic mesh repair of giant hiatal hernia. Two cases of missing follow up were excluded. Patients were divided into an elderly group (N=62, age ≥75) and a younger group (N=88, age <75). Interrupted non-absorbable suture was applied for crus closure and as an additional reinforcement, the mesh was fixed with absorbable tacks or medical glue. Procedure-related complications, score-based variation tendency of symptoms, gastrointestinal quality of life index (GIQLI), mortality, recurrence rate, hemoglobin, and the use of PPI were investigated.

Results

All patients underwent the procedure uneventfully. Dor fundoplication was used in 39 patients (62.9%) in the elderly group and 44 (50.0%) in the younger group and no case was converted to open. While the elderly group had a significantly higher percentage of ASA Class level 3 and cardiovascular and cerebrovascular diseases as compared to the younger group, the two groups had similar operative times, intraoperative blood loss, and percentage of intrathoracic stomach. Elderly group patients tended to have higher perioperative complications including pneumonia (3.2%) and atelectasis (3.2%) without statistical significance, as well as transfer to the intensive care unit compared, to younger patients (9.7% vs. 3.2%; P=0.144). The mean post-operative hospital stay was also significantly shorter in the younger group (2.8 days) compared with the elderly group (3.5 days; P=0.001). There was no mortality, recurrence, mesh-related complications such as visceral erosion, adhesion, or severe dysphagia during follow up in the two groups, and both groups demonstrated significant improvement in GIQLI scores and hemoglobin. The percentage of patients who needed PPI was also reduced in both groups.

Conclusions

Laparoscopic mesh repair of giant hiatal hernia for elderly patients is safe and effective when performed at experienced centers.

Reflux Aspiration Associated with Oesophageal Dysmotility but Not Delayed Liquid Gastric Emptying

INTRODUCTION

Severe oesophageal dysmotility is associated with treatment-resistant reflux and pulmonary reflux aspiration. Delayed solid gastric emptying has been associated with oesophageal dysmotility; however, the role of delayed liquid gastric emptying (LGE) in the pathophysiology of severe reflux disease remains unknown. The purpose of this study is to examine the relationship between delayed LGE, reflux aspiration, and oesophageal dysmotility.

METHODS

Data were extracted from a prospectively populated database of patients with severe treatment-resistant gastro-oesophageal reflux disease. All patients with validated reflux aspiration scintigraphy and oesophageal manometry were included in the analysis. Patients were classified by predominant clinical subtype as gastro-oesophageal reflux (GOR) or laryngopharyngeal reflux. LGE time of 22 min or longer was considered delayed.

RESULTS

Inclusion criteria were met by 631 patients. Normal LGE time was found in 450 patients, whilst 181 had evidence of delayed LGE. Mean liquid half-clearance was 22.81 min. Reflux aspiration was evident in 240 patients (38%). Difference in the aspiration rates between delayed LGE (42%) and normal LGE (36%) was not significant (p = 0.16). Severe ineffective oesophageal motility (IOM) was found in 70 patients (35%) and was independent of LGE time. Severe IOM was strongly associated with reflux aspiration (p < 0.001). GOR dominant symptoms were more common in patients with delayed LGE (p = 0.03).

CONCLUSION

Severe IOM was strongly associated with reflux aspiration. Delayed LGE is not associated with reflux aspiration or severe IOM. Delayed LGE is more prevalent in patients presenting with GOR dominant symptoms.

Does composite repair of giant paraoesophageal hernia improve patient outcomes?

BACKGROUND

Paraoesophageal hernia (PEH) is often symptomatic and reduces patients' quality of life (QoL). There is ongoing debate regarding the most effective surgical technique to repair giant PEH. This study aimed to see if an elective laparoscopic non-mesh composite technique of giant PEH repair offered an advantage in symptom control, hernia recurrence, QoL, morbidity and mortality.

METHODS

Data were extracted from a prospectively maintained database of patients undergoing hiatal hernia repair. Composite hernia repairs from inception for giant PEH between March 2009 and December 2015 were included. Perioperative mortality, complications, hernia recurrence rates, prevalence, recurrence of symptoms and QoL were included in analysis.

RESULTS

Inclusion criteria were met by 218 patients. Mean age was 70 (49-93). The average hernia size was 62% (range 30-100%; SD 21). There was one perioperative death and three significant complications (Clavien-Dindo grade III and IV). Recurrence rate was 24.8%. Without recurrence, QoL improved significantly across all domains. Recurrence of hiatus hernia reduced QoL. Surgery resulted in resolution of symptoms other than dysphagia which was incompletely improved. Patients' overall satisfaction with surgery was high.

CONCLUSION

Composite repair of giant PEH is safe with overall good outcomes. Majority of hernia recurrence are small and asymptomatic. Hernia recurrence negatively affected long-term QoL scores.

The natural course of giant paraesophageal hernia and long-term outcomes following conservative management

Background

Accurate information on the natural course of giant paraesophageal hernia is scarce, challenging therapeutic decisions whether or not to operate.

Objective

We aimed to investigate the long-term outcomes, including hernia-related deaths and complications (e.g. volvulus, gastrointestinal bleeding, strangulation) of patients with giant paraesophageal hernia that were conservatively managed, and to determine factors associated with clinical outcome.

Methods

We retrospectively analysed charts of patients diagnosed with giant paraesophageal hernia between January 1990 and August 2019, collected from a university hospital in The Netherlands. Included patients were subdivided into three groups based on primary therapeutic decision at diagnosis. Radiological, clinical and surgical characteristics, along with long-term outcomes at most recent follow-up, were collected.

Results

We included 293 patients (91 men, mean age 70.3 ± 12.4 years) with a mean duration of follow-up of 64.0 ± 58.8 months. Of the 186 patients that were conservatively treated, a total hernia-related mortality of 1.6% was observed. Hernia-related complications, varying from uncomplicated volvulus to strangulation, occurred in 8.1% of patients. Only 1.1% of patients included in this study required emergency surgery. Logistic regression analysis revealed the presence of symptoms (odds ratio (OR) 4.4, 95% confidence interval (CI) 1.8–20.6), in particular obstructive symptoms (vomiting, OR 15.7, 95% CI 4.6–53.6; epigastric pain, OR 4.4, 95% CI 1.2–15.8 and chest pain, OR 6.1, 95% CI 1.8–20.6) to be associated with the occurrence of hernia-related complications.

Conclusions

Hernia-related death and morbidity is low in conservatively managed patients. The presence of obstructive symptoms was found to be associated with the occurrence of complications during follow-up. Conservative therapy is an appropriate therapeutic strategy for asymptomatic patients.

The use of biosynthetic mesh in giant hiatal hernia repair: is there a rationale? A 3-year single-center experience

PURPOSE

Reinforced prosthetic crural repair is particularly indicated for giant hiatal hernias. The rationale is to reduce the recurrence rate in the long term. The aim of our study is to evaluate the outcomes of laparoscopic giant hiatal hernia repair using a biosynthetic mesh.

METHODS

We retrospectively analyzed 44 patients who underwent laparoscopic mesh-reinforced hiatal closure and fundoplication using a biosynthetic material. Inclusion criterion was large hiatal defects (> 5 cm). Follow-up was scheduled at 6, 12 and 36 months after surgery.

RESULTS

44 patients (29F) with a mean age of 62 years (range 14-85) and mean of BMI 24.5 kg/m² (range 21-29) underwent successful laparoscopic repair. Twenty-six (59.1%) patients had Nissen-Rossetti fundoplication, whereas 18 (40.9%) had Toupet fundoplication. Six-month questionnaire for the evaluation of symptoms was available for 43 patients (97.7%) and for 40 (90.9%) patients at 12 and 36 months. Mean preoperative symptoms score analysis was 1.68 ± 0.73. Mean scores at each follow-up time were significantly improved compared to baseline (p > 0.05). Barium swallow was available in 37 patients (84.1%) at 1 year after surgery. Radiologic recurrence was observed in two patients (4.5%). No patient had symptoms attributable to recurrence or required revisional surgery. There were no mesh-related complications at 3 years follow-up.

CONCLUSIONS

The use of biosynthetic mesh for crural reinforcement is associated with a low incidence of mesh-related complications and with a reasonably low recurrence rate (4.5%) at 36 months. However, additional data with longer follow-up are needed to determine long-term safety and efficacy.

Minimally invasive laparoscopic and robot-assisted emergency treatment of strangulated giant hiatal hernias: report of five cases and literature review

Background

Giant hiatal hernia (GHH) is a condition where one-third of the stomach migrates into the thorax. Nowadays, laparoscopic treatment gives excellent postoperative outcomes. Strangulated GHH is rare, and its emergent repair is associated with significant morbidity and mortality rates. We report a series of five cases of strangulated GHH treated by a minimally invasive laparoscopic and robot-assisted approach, together with a systematic review of the literature.

Methods

During 10 years (December 2009–December 2019), 31 patients affected by GHH were treated by robot-assisted or conventional laparoscopic surgical approach. Among them, five cases were treated in an emergency setting. We performed a PubMed MEDLINE search about the minimally invasive emergent treatment of GHH, selecting 18 articles for review.

Results

The five cases were male patients with a mean age of 70 ± 18 years. All patients referred to the emergency service complaining of severe abdominal and thoracic pain, nausea and vomiting. CT scan and endoscopy were the main diagnostic tools. All patients showed stable hemodynamic conditions so that they could undergo a minimally invasive attempt. The surgical approach was robotic-assisted in three patients (60%) and laparoscopic in two (40%). Patients reported no complications or recurrences.

Conclusion

Reviewing current literature, no general recommendations are available about the emergent treatment of strangulated hiatal hernia. Acute mechanical outlet obstruction, ischemia of gastric wall or perforation and severe bleeding are the reasons for an emergent surgical indication. In stable conditions, a minimally invasive approach is often feasible. Moreover, the robot-assisted approach, allowing a stable 3D view and using articulated instruments, represents a reasonable option in challenging situations.

How high is too high? Extensive mediastinal dissection in patients with hiatal hernia repair

BACKGROUND

Approximately 10% of patients receiving anti-reflux procedures present with shortened esophagus. Collis gastroplasty (CG) is the current gold standard for esophageal lengthening, but mediastinal esophageal mobilization without gastroplasty may be an alternative approach. This study assesses preoperative and intraoperative hernia characteristics and mediastinal dissection impact in patients with large hiatal hernia repair (HHR).

METHODS

A single-institution, prospectively collected database was reviewed for adults who underwent laparoscopic HHR with mesh and anti-reflux surgery between 2005 and 2016, hernia ≥ 5 cm. Preoperative hernia and follow-up were assessed using upper endoscopy and barium swallow. Intraoperative hernia characteristics were collected from the operative note. Esophageal symptom scores were collected pre- and postoperatively. Analyses were conducted using SPSS v26.0.

RESULTS

Among 662 patients who had anti-reflux surgery in this period, a total of 205 patients who underwent HHR with mesh met the inclusion criteria and were included in study. Mean age was 61.7 ± 13.6 years, and majority of patients were female and Caucasian. Mean BMI was 29.9 ± 6.0 kg/m². Median hernia size was 6.5 cm [5.0-12.0 cm], and intra-thoracic stomach had a prevalence of 21.9%. Analysis of preoperative barium swallow revealed an average of elevated gastroesophageal junction above the diaphragm of 4.10 ± 1.67 cm. Radiographically, average hernia size was 6.34 ± 1.93 cm and 6.38 ± 1.92 cm in the anterior-posterior and obliquus view, respectively. Median follow-up time was 2.7 years [1-9 years]. Esophageal symptoms improved in all patients (p < 0.05). 45% of patients had radiographic recurrence, but only four presented symptomatic or were on PPI.

CONCLUSIONS

CG has been the standard for ensuring adequate esophageal length prior to anti-reflux surgery. Our results support that CG is unnecessary in the majority of cases, and extensive mediastinal dissection was successfully used instead of CG with durable, long-term outcomes. Extended mediastinal dissection may mitigate CG risks in patients requiring additional intra-abdominal esophagus.

Health-related quality of life after laparoscopic repair of giant paraesophageal hernia: how does recurrence in CT scan compare to clinical success?

Background

Computed tomography (CT) is widely used in the diagnosis of giant paraesophageal hernias (GPEH) but has not been utilised systematically for follow-up. We performed a cross-sectional observational study to assess mid-term outcomes of elective laparoscopic GPEH repair. The primary objective of the study was to evaluate the radiological hernia recurrence rate by CT and to determine its association with current symptoms and quality of life.

Methods

All non-emergent laparoscopic GPEH repairs between 2010 to 2015 were identified from hospital medical records. Each patient was offered non-contrast CT and sent questionnaires for disease-specific symptoms and health-related quality of life.

Results

The inclusion criteria were met by 165 patients (74% female, mean age 67 years). Total recurrence rate was 29.3%. Major recurrent hernia (> 5 cm) was revealed by CT in 4 patients (4.3%). Radiological findings did not correlate with symptom-related quality of life. Perioperative mortality occurred in 1 patient (0.6%). Complications were reported in 27 patients (16.4%).

Conclusions

Successful laparoscopic repair of GPEH requires both expertise and experience. It appears to lead to effective symptom relief with high patient satisfaction. However, small radiological recurrences are common but do not affect postoperative symptom-related patient wellbeing.

Reparación laparoscópica de hernia hiatal gigante

Introducción. La reparación laparoscópica es el estándar de tratamiento en hernia hiatal gigante. Sin embargo, a pesar de su baja morbilidad, la tasa de recurrencia sigue siendo alta. Nuestro objetivo fue describir los resultados de la reparación laparoscópica de hernia hiatal gigante, independientemente de la técnica de cruroplastia empleada. Métodos. Se llevó a cabo un estudio retrospectivo de pacientes llevados a reparación laparoscópica de hernia hiatal gigante en el periodo 2009-2017. Se analizaron los datos demográficos, la técnica quirúrgica, las complicaciones y la estancia hospitalaria. Se revisaron los resultados de la endoscopia, la radiografía de vías digestivas altas y la escala de síntomas GERD-HRQOL, obtenidos luego de un año de cirugía. Resultados. Se incluyeron 44 pacientes con un tamaño promedio de la hernia de 7 cm. Se practicó cruroplastia con sutura simple en 36,4 %, sutura más refuerzo con politetrafluoroetileno (PTFE) o dacrón, en 59,1 %, y se usó malla en 4,5 %. Hubo 12 complicaciones, la estancia hospitalaria promedio fue de 3,5 días y no hubo mortalidad. Se encontró recurrencia endoscópica o radiológica en 6/20 pacientes, todas pequeñas y asintomáticas. En 23 pacientes, la escala GERD-HRQOL reportó un valor promedio de 7,7 y 78 % de satisfacción. Solo un paciente requirió cirugía de revisión. Conclusión. El método preferido de reparación laparoscópica de la hernia hiatal gigante es la cruroplastia sin malla, técnica asociada a baja morbilidad y adecuado control de los síntomas. La tasa de recurrencia es similar a la reportada en la literatura. Se requieren estudios prospectivos con seguimiento completo a largo plazo para validar estos resultados.

Laparoscopic repair of complete intrathoracic stomach with iron deficiency anemia: A case report

BACKGROUND

Giant paraesophageal hiatal hernias (HH) are very infrequent, and their spectrum of clinical manifestations is large. Giant HH mainly occurs in elderly patients, and its relationship with anemia has been reported. For the surgical treatment of large HH, Nissen fundoplication is the most common antireflux procedure, and the reinforcement of HH repair with a patch (either synthetic or biologic) is still debatable.

CASE SUMMARY

We report on a case of giant paraesophageal HH in a middle-aged male patient with reflux symptoms and severe anemia. After performing a series of tests and diagnostic approaches, results showed a complete intrathoracic stomach associated with severe iron deficiency anemia. The patient underwent successful laparoscopic hernia repair with mesh reinforcement and Nissen fundoplication. Postoperatively, reflux symptoms were markedly relieved, and the imaging study showed complete reduction of the hernia sac. More importantly, anemia was resolved, and hemoglobin, serum iron and ferritin level were returned to the normal range. The patient kept regular follow-up appointments and remained in a satisfactory condition.

CONCLUSION

This case report highlights the relationship between large HH and iron deficiency anemia. For the surgical treatment of large HH, laparoscopic repair of large HH combined with antireflux procedure and mesh reinforcement is recommended.

Massive hiatal hernia involving prolapse of the entire stomach and pancreas resulting in pancreatitis and bile duct dilatation: a case report

Background

Hiatal hernia is defined by the permanent or intermittent prolapse of any abdominal structure into the chest through the diaphragmatic esophageal hiatus. Prolapse of the stomach, intestine, transverse colon, and spleen is relatively common, but herniation of the pancreas is a rare condition. We describe a case of acute pancreatitis and bile duct dilatation secondary to a massive hiatal hernia of pancreatic body and tail.

Case presentation

An 86-year-old woman with hiatal hernia who complained of epigastric pain and vomiting was admitted to our hospital. Blood tests revealed a hyperamylasemia and abnormal liver function test. Computed tomography revealed prolapse of the massive hiatal hernia, containing the stomach and pancreatic body and tail, with peripancreatic fluid in the posterior mediastinal space as a sequel to pancreatitis. In addition, intrahepatic and extrahepatic bile ducts were seen to be dilated and deformed. After conservative treatment for pancreatitis, an elective operation was performed. There was a strong adhesion between the hernial sac and the right diaphragmatic crus. After the stomach and pancreas were pulled into the abdominal cavity, the hiatal orifice was closed by silk thread sutures (primary repair), and the mesh was fixed in front of the hernial orifice. Toupet fundoplication and intraoperative endoscopy were performed. The patient had an uneventful postoperative course post-procedure.

Conclusion

A rare massive hiatal hernia, involving the stomach and pancreatic body and tail, can cause acute pancreatitis with bile duct dilatation. The etiology can be flexure of the main pancreatic and extrahepatic bile ducts. Symptomatic herniation is best treated with surgery. Elective surgery is thought to be safer than emergent surgery in patients with serious complications.

Preoperative Evaluation and Clinical Decision Making for Giant Paraesophageal Hernias: Who Gets an Operation?

Giant paraesophageal hernias can present as an asymptomatic incidentally detected paraesophageal hernia to an emergent gastric volvulus with concern for ischemia. In the acute setting, the preoperative evaluation aims to determine the extent of complications from gastric volvulus. In the elective setting, preoperative testing defines the gastroesophageal anatomy and function to select the optimal operation. Through thoughtful preoperative evaluation, the best operative approach can be tailored to each patient.

Transhiatal Herniation as the Cause of Acute Pancreatitis After Toupet Fundoplication

Hiatal translocation of the pancreas is rare because of its retroperitoneal location. Acute pancreatitis as a complication of hiatal hernia is uncommon. A 33-year-old man presented for 2 days of worsening epigastric abdominal pain and substernal chest pain. Laboratory studies were essentially unremarkable; however, computed tomography demonstrated a large right-sided hiatal hernia containing the entire stomach and the body of the pancreas, with peripancreatic edema consistent with pancreatitis. Most cases can be managed conservatively; however, elective surgical repair is suggested in severe cases or patients with low surgical risk.

The other explanation for dyspnea: giant paraesophageal hiatal hernia repair routinely improves pulmonary function

Paraesophageal hiatal hernias (PEHs) are most commonly associated with gastrointestinal symptoms; less widely appreciated is their potentially important influence on respiratory function. We hypothesize that surgical repair of PEH will significantly improve not only gastrointestinal symptoms, but also preoperative dyspnea and spirometry scores. A prospective Institutional Review Board-approved database was used to review all patients undergoing PEH repair from 2000 to 2016. Patients with pre- and postoperative pulmonary function tests assessed by spirometry were included. Postoperative changes in spirometry measurements were compared to PEH size as reflected by the percentage of intrathoracic stomach observed on preoperative contrast studies. Patients were stratified according to improvement in forced expiratory volume in 1 second (FEV1). Patients with >12% ('significant') improvement in FEV1 after surgery were compared to the remaining patient population. In total, 299 patients met the inclusion criteria. Symptomatic improvement in respiratory function was noted in all patients after PEH repair. Age, gender, BMI, presenting symptoms, Charlson comorbidity index as well as preoperative comorbidities did not significantly impact the functional outcome. Spirometry results improved in 80% of the patients, 21% of whom showed an improvement of >20% compared to the preoperative level. 'Significant' improvement in respiratory function was seen in 122 of 299 (41%) patients. Patients presenting with moderate and severe preoperative pulmonary obstruction demonstrated 'significant' improvement in FEV1 in 48% and 40% of cases, respectively. Large PEHs, characterized by a percentage of intrathoracic stomach >75%, was strongly associated with 'significant' improvement in FEV1 (P = 0.001). PEHs can impact subjective and objective respiratory status and surgical repair can result in a significant improvement in dyspnea and pulmonary function score that is independent of preoperative pulmonary disease. Gastric herniation of more than 75% was associated with higher possibility for improvement of pulmonary function tests. Patients with persistent and unexplained dyspnea and coexistent PEH should be assessed by an experienced surgeon for consideration of elective repair.

Minimally invasive surgery for large hiatal hernia

The majority of large hiatal hernias are paraesophageal hiatal hernias (PEH). Once prolapse of the stomach to the chest cavity reaches a high degree, it is called an intrathoracic stomach. More than 25 years have elapsed since laparoscopic surgery was carried out as minimally invasive surgery for PEH. The feasibility and safety thereof has nearly been established. PEH may cause serious complications such as strangulation and perforation. The outcome of elective repair of PEH is better than emergent repair, so we should carry out elective repair as much as possible. Although not a major clinical problem, following PEH repair the rate of anatomical recurrence increases with age. In order to reduce the recurrence rate, mesh reinforcement by crural repair has been widely performed. Although this improves the short-term outcomes, the long-term outcomes are unclear. For PEH repair, fundoplication and gastropexy are believed desirable. We should select the procedure associated with a lower incidence of dysphagia and so on following surgery. While relaxing incision is useful for primary tension-free closure, it has not contributed to improvement in the recurrence rate.

Robot-assisted Toupet fundoplication and associated cholecystectomy in symptomatic giant hiatal hernia with situs viscerum inversus-A case report and literature review

•

All symptomatic paraesophageal hiatal hernias should be repaired, particularly those with acute obstructive symptoms or which have undergone volvulus.

•

Laparoscopic hiatal hernia repair is as effective as open transabdominal repair, with a reduced rate of perioperative morbidity and with shorter hospital stays. It is the preferred approach for the majority of hiatal hernias.

Robotic Assisted Giant-Paraesophageal Hernia repair remain technically challenging predominantly in the dissecation of the hernia sac from the posterior mediastinum.

•

The robotic platform have the same benefits of the laparoscopic approach in terms of complication rate, total surgical time, and hospital length of stay and in particular case is superior.

Introduction

Giant hiatus hernia is defined as migration of >30% of the stomach with or without other intra-abdominal organs into the chest. Situs Viscerum Inversus is a rare congenital condition in which the major visceral organs are reversed from their normal arrangement; they are translated (completely or partially) on the opposite side of the body. Diagnosis is often incidental. We report a Robot-assisted Toupet fundoplication for a giant hiatal hernia with gastro oesophageal reflux disease and cholelithiasis, in a 63-years-old woman with situs viscerum inversus.

Presentation of case

A 63-year-old woman with Situs Viscerum Inversus was diagnosed with giant sliding hiatus hernia. We performed a Robot-assisted procedure of reduction of hiatal hernia in abdomen and Toupet fundoplication with Bio A mesh placement and gastropexy procedure associated to cholecystectomy. The operation time was of 190 min. The patient was discharged on third postoperative day after X-ray check and he tolerated a solid food.

Discussion

Minimally invasive surgery represents, nowadays, the standard approach for hiatal hernia and cholelithiasis.

Conclusion

In challenging cases as the giant hernias ad rare anomaly as situs viscerum inversus, the surgical treatment can be facilitated by the use of robotic technology.

The first year is the hardest: a comparison of early versus late experience after the introduction of robotic hiatal hernia repair

While the majority of the literature written concerning minimally invasive hiatal hernia repair involves laparoscopy, little has been written concerning the transition to a robotic technique. We present our experience, with a transparent analysis of data, with regard to the introduction of robotic paraesophageal hernia (PEH) repair by an experienced laparoscopic surgeon. We reviewed our first 30 consecutive patients who underwent robotic PEH over a 2-year period after the introduction of robotic surgery at our institution. Patients were divided into two groups: the early experience group (procedures performed within the first year of introduction of robotic technique, n = 13) and a late experience group (procedures performed in the second year, n = 17). All procedures were performed by a single experienced foregut surgeon. The mean operative time for the early group was significantly greater than for the late group, 184 min versus 142 min, respectively (p < 0.01). Four patients in the early group required conversion to open, while zero patients in the late group required conversion (p = 0.03). Patient demographics and complications did not differ significantly between the two patient populations. The early robotic hiatal hernia repair experience can be more difficult than expected, even in the hands of an experienced laparoscopic team. We identify several areas of improvement including patient positioning, operating room team training, and technical experience. This data can help other surgeons prepare for the transition to robotic foregut surgery.

Increasing rate of para-oesophageal hiatus hernia surgical repair within Australia

BACKGROUND

Symptomatic para-oesophageal hiatus (PEH) hernias are treated by surgical intervention, and are associated with older age (>50 years) and higher body mass index (>25 kg/m² ). Both risk factors are increasing within the Australian population. Given these trends, this study aimed to determine if the rate of PEH repair is increasing within Australia.

METHODS

The study used publically available Medicare Benefits Scheme service data for operations claimed under the item number 31468 (PEH hernia, repair of, with complete reduction of hernia, resection of sac and repair of hiatus, with or without fundoplication) between 1 January 2001 and 31 December 2016. Directly age-standardized rates per 100 000 population were calculated using the 2001 Australian standard population and compared using Poisson regression models.

RESULTS

Repair of PEH significantly increased (P < 0.0001) in Australia during this period, with the average number of services increasing by 14.6% per annum. Average rates of repair increased significantly (P < 0.001) with increasing age up to 75 years after which they significantly reduced (P < 0.001) in each successive age group. Western Australia had the greatest increase in annual claims and Northern Territory had the least, but the state-specific average claim rate over the whole period was highest in Queensland and lowest in Northern Territory.

CONCLUSION

Operations claimed under Medicare Benefits Scheme item number 31468 have significantly increased in Australia since January 2001. Reasons for this rise are likely multifactorial, and may indicate increasing PEH incidence, increased diagnosis and investigation or increased surgical capability to manage the issue laparoscopically with reduced peri-operative morbidity.

Laparoscopic repair of type III/IV giant para-oesophageal herniae with biological prosthesis: a single centre experience

PURPOSE

Repair of giant paraoesophageal herniae (GPEH) is technically challenging and requires significant experience in advanced foregut surgery. Controversy continues on suture versus mesh cruroplasty with the most recent systematic review and meta-analysis putting the onus on the operating surgeon. Study aim was to review whether the biological prosthesis (non-cross-linked bovine pericardium and porcine dermis) and the technique adopted for patients with GPEH had an influence on clinical and radiological recurrences.

METHOD

A retrospective analysis of a prospectively collected data of 60 consecutive patients with confirmed 5 cm hiatus hernia and ≥ 30% stomach displacement in the thorax that were operated in the upper gastrointestinal unit of a large district general hospital between September 2010 and August 2017. Pre and post-surgery Gastro-Oesophageal Reflux Disease Questionnaire [(GORD-HRQOL)] and a follow up contrast study were completed.

RESULTS

60 included 2 (3%) and 58 (97%) emergency and elective procedures respectively with a male: female ratio of 1:3, age 71* (Median) (42-89) years, BMI 29* (19-42) and 26 (43%) with ASA III/IV. Investigations confirmed 46* (37-88) mm and 42* (34-77) mm transverse and antero-posterior hiatal defect respectively with 60* (30-100)% displacement of stomach into chest. Operative time and length of stay was 180* (120-510) minutes and 2* (1-30) days respectively. One (2%) converted for bleeding and 2 (3%) peri-operative deaths. Five (8%), 5 (8%) and 4 (7%) have dysphagia, symptomatic and radiological recurrences respectively. GORD-HRQOL recorded preoperatively was 27* (10-39) dropping significantly postoperatively to 0* (0-21) (P < 0.005) with 95% patient satisfaction at a follow up of 60* (36-84) months.

CONCLUSIONS

Our technique of laparoscopic GPEH repair with biological prosthesis is safe with a reduced symptomatic and radiological recurrence and an acceptable morbidity and mortality.
