Management of large para-esophageal hiatal hernias

Safety and Early Clinical Outcomes Following Repair of Very Large Hiatus Hernia in Octogenarians

BACKGROUND

Very large hiatus hernias are often symptomatic, impact quality of life, and are increasingly encountered in aging populations. Laparoscopic repair offers excellent clinical outcomes. However, surgeons can be reluctant to offer surgery to the elderly due to concerns about morbidity and mortality. To determine safety, we evaluated outcomes following repair of very large hiatus hernias in patients aged 80 years and older and compared them to younger patients.

METHODS

Data were extracted from a prospective database. Patients who underwent operative repair of a very large hiatus hernia (> 50% intrathoracic stomach) between 2000 and 2023 were included and categorized into groups based on age: young (< 70 years), older (70-79 years), and octogenarian (≥ 80 years). Perioperative and early postoperative clinical outcomes were determined and compared.

RESULTS

1353 patients underwent surgery (< 70 years: 733 [54.2%], 70-79 years: 451 [33.3%], and ≥ 80 years: 169 [12.5%]). Rates of total intrathoracic stomach were commonest in octogenarians (11.6% vs. 20.4% vs. 32.5% and p < 0.001). Young and older patients were more likely to undergo elective surgery for heartburn (56.6% vs. 44.4% vs. 29.0% and p < 0.001), whereas octogenarians more likely underwent emergency surgery for gastric volvulus (5.4% vs. 6.6% vs. 14.5% and p = 0.019). Conversion to open surgery (1.1% vs. 1.1% vs. 5.0% and p = 0.002) and length of stay (2.69 vs. 3.19 vs. 4.62 days and p < 0.001) were greater in the octogenarian group. Major complications (4.2% vs. 5.1% vs. 8.1% and p = 0.120) and return to theater rates (2.6% vs. 2.9% vs. 2.7% and p = 0.925) were similar. Thirty-day mortality rates were low for all groups but highest in octogenarians (0.3% vs. 0.4% vs. 1.8% and p = 0.048). Adverse outcomes were more likely with emergency presentations, which were more common in octogenarians.

CONCLUSION

Despite a higher rate of emergency surgery in octogenarians-major complications and overall mortality rates are still acceptably low. Repair of very large symptomatic hiatus hernia should not be withheld from patients aged over 80 who are otherwise fit.

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.

Robotic surgery for giant paraesophageal hernias: a promising approach to improved outcomes

Giant paraesophageal hernias (GPEH) present challenges in management and surgical technique. Laparoscopic repair has been the gold standard for GPEH repair. Despite technical advances in laparoscopy, complications and recurrence remain high. The da Vinci Surgical System has emerged as a way to improve upon the gold standard. The objective of this study is to evaluate clinical outcomes of patients who underwent robotic GPEH repair in comparison to the clinical data in the literature on laparoscopic GPEH repair. We retrospectively reviewed patient records who underwent GPEH repair between November 2012 and February 2023 at a single high-volume tertiary care center. Perioperative data and patient outcomes were collected from a prospectively maintained database. Ninety-two patients underwent robotic GPEH repair. Sixty-seven had Type III hernias (72.8%) and twenty-five had Type IV hernias (27.2%). Four (4.3%) required conversion to open repair and two (2.2%) required reoperation for recurrence. Twelve (13.0%) experienced complications including one surgical complication (splenic laceration) and eleven medical complications (fever, ileus, pleural effusion, and heart failure exacerbation). There was no perioperative mortality. Mean operative time was 166.4 ± 29.5 min, and hospital stay was 5.8 ± 3.1 days. Obesity (BMI > 30) was associated with higher complication and recurrence rates. Robotic GPEH repair demonstrates promising outcomes, with lower recurrence rates and fewer postoperative complications compared to published data on laparoscopic repair. While a randomized control trial is needed to substantiate these results, our data support that a robotic approach could become the standard of care for GPEH repair.

Quality of life following repair of large hiatal hernia is not influenced by the use of mesh-Longer-term follow-up from a randomized trial

INTRODUCTION

The use of prosthetic mesh in laparoscopic repair of large hiatus hernias remains controversial. Clinical and quality of life outcomes from a randomized controlled trial of mesh versus suture repair previously showed few differences at early follow-up. This study evaluated longer-term quality of life outcomes from that trial.

METHODS

A prospective, multicentre, double blind randomized controlled trial assessed three methods of repair for large hiatus hernias: sutures-only versus absorbable mesh versus non-absorbable mesh. Quality of life was assessed using the Short-Form 36 (SF-36) questionnaire which was completed preoperatively and then at 3, 6, 12 months following surgery and annually thereafter. SF-36 outcomes were compared across the three repair techniques at longer-term follow-up (3-6 years), and to earlier baseline and 12-month outcomes.

RESULTS

126 patients were randomized; 43-suture-only, 41-absorbable mesh and 42-non-absorbable mesh. Questionnaires were completed by 118 patients preoperatively, 115 at 12 months and 98 at longer-term follow-up (median 5 years). There were no significant differences between the repair techniques for the subscale and composite scores at longer-term follow-up. The mental component score improved significantly after surgery and was sustained across follow-up for all techniques. The physical component score also improved significantly but was lower at longer-term follow-up compared to the 12-month follow up in both mesh groups.

CONCLUSION

Surgical repair of large hiatus hernias provides sustained long-term improvement in quality of life. The addition of mesh does not improve quality of life.

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.

A Rare Case of Paraesophageal Hernia Repair Complicated by Pancreatic Injury

Esophageal hernias are anatomical defect that affects up to 50% of the population. While they may be asymptomatic, hernias may also result in reflux and dysphagia, among other symptoms. In such cases, hernia repair is warranted. The most common type of repair is laparoscopic Nissen fundoplication, which is usually well-tolerated. Herein, we present a rare case of paraesophageal hernia repair complicated by pancreatic injury and pancreatic leak.

Late presentation of congenital type IV esophageal hiatus hernia in a 9-year-old boy: a case report

Background

Congenital diaphragmatic hernia affects 1 in every 2000–5000 live births. The mediastinum shifts to the opposite side, the lungs are hypoplastic, and the arterioles are abnormal, resulting in pulmonary hypertension. Respiratory and cardiovascular functions are severely impaired at birth, resulting in significant mortality and morbidity as a result of the associated malformations.

Case presentation

A 9-year-old persian boy was referred with complaint of intermittent abdominal pain in the left lower quadrant and an episode of vomiting. The patient was tachypneic, and the abdomen was nontender on examination. Lung sounds on the left side were considerably decreased, whereas heart sounds on the right side were louder. There was no history of underlying disease in the patient. Initial laboratory blood tests, chest x-ray, spiral computed tomography scan, and chest sonography were requested. Blood tests were normal, and chest x-ray revealed a round-shaped lesion with relatively clear boundaries containing air–fluid level and shift of the heart and mediastinum to the right. A spiral computed tomography scan of the lungs demonstrated the shift of the heart and mediastinum to the right side was due to dilated stomach and colon pressure, and chest sonography revealed that half of the stomach was inside the thorax. Laparotomy surgery was performed. The patient had no complications following surgery.

Conclusions

Herniation of abdominal contents through the diaphragmatic hiatus should be suspected in patients with tachypnea and mediastinal shift to the right side. Rapid diagnosis and early surgical treatment are necessary to avert any potentially life-threatening complications.

'Back-and-Forth Stomach' CT Imaging Findings of a Pathophysiologic Entity Causing Acute Gastric Volvulus

BACKGROUND

Gastric volvulus (GV) is a life-threatening emergency condition that prompts emergent surgical management. With the advent of high-resolution computed tomography (CT), the role of radiologists in its diagnosis has become essential. Although many cases of GV have been described in the literature, its pathophysiology is still poorly understood. In addition, there is substantial terminological confusion with associated entities such as paraesophageal hernia, upside-down stomach, organo-axial or chronic GV.

METHODS

We conducted a retrospective review of clinical, radiological findings and other relevant data for seven patients with previous radiological diagnoses of a large hiatus hernia who presented with acute GV to the emergency department of our institution. We report data on age, sex, medical history, clinical presentation, imaging, treatment and outcomes for each case.

RESULTS

The CT findings at acute presentation showed the antrum lying above the diaphragm and dilated fundus below the diaphragm. By comparing the position of the stomach at acute presentation with previous imaging examinations, we confirmed a hypothesis put forward by a few authors decades ago that re-herniation of the gastric fundus into the abdomen is a common pathophysiologic trigger leading to acute GV. This hypothesis has not been supported by modern imaging examinations.

CONCLUSIONS

We have provided imaging evidence supporting that the pathophysiology of many GVs is based on caudal re-descent of hiatal hernia into the abdominal cavity. Given the terminological disparity used in the literature in this context, we believe it appropriate to introduce and extend the term 'back-and-forth stomach' to refer to this type of GV.

Quality of life and symptom assessment in paraesophageal hernias: a systematic literature review of reporting standards

BACKGROUND

Paraesophageal hernias (PEH) present with a range of symptoms affecting physical and mental health. This systematic review aims to assess the quality of reporting standards for patients with PEH, identify the most frequently used quality of life (QOL) and symptom severity assessment tools in PEH and to ascertain additional symptoms reported by these patients not captured by these tools.

METHODS

A systematic literature review according to PRISMA protocols was carried out following a literature search of MEDLINE, Embase and Cochrane databases for studies published between January 1960 and May 2020. Published abstracts from conference proceedings were included. Data on QOL tools used and reported symptoms were extracted.

RESULTS

This review included 220 studies reporting on 28 353 patients. A total of 46 different QOL and symptom severity tools were used across all studies, and 89 different symptoms were reported. The most frequently utilized QOL tool was the Gastro-Esophageal Reflux Disease-Health related quality of life questionnaire symptom severity instrument (47.7%), 57.2% of studies utilized more than 2 QOL tools and 'dysphagia' was the most frequently reported symptom, in 55.0% of studies. Notably, respiratory and cardiovascular symptoms, although less common than GI symptoms, were reported and included 'dyspnea' reported in 35 studies (15.9%).

CONCLUSIONS

There lacks a QOL assessment tool that captures the range of symptoms associated with PEH. Reporting standards for this cohort must be improved to compare patient outcomes before and after surgery. Further investigations must seek to develop a PEH specific tool, that encompasses the relative importance of symptoms when considering surgical intervention and assessing symptomatic improvement following surgery.

Fundic gastropexy for high risk of recurrence laparoscopic hiatal hernia repair and esophageal sphincter augmentation (LINX) improves outcomes without altering perioperative course

BACKGROUND

The aim of this study is to show that the addition of a fundic gastropexy to a laparoscopic hiatal hernia repair (HHR) and magnetic sphincter augmentation (MSA) with LINX (Johnson and Johnson, New Brunswick, NJ) in patients with high risk for hiatal hernia recurrence improves outcomes without altering perioperative course.

METHODS

An IRB approved, single institution retrospective review of patient outcomes after hiatal hernia repair with magnetic sphincter augmentation was performed. Data were obtained from the electronic health record and stored in a REDCap database. Using statistical software, the patient data were analyzed and stratified to assess the specific variables of the perioperative and postoperative course focusing on the high risk of hiatal hernia recurrence group (HRHR) and low risk hiatal hernia of recurrence group (LRHR). The HRHR group received a gastropexy and were defined using the following variables: comorbid state increasing abdominal pressure, gastric herniation > 30%, maximum transverse crural diameter > 4 cm, age 70 years or older, previous hiatal or abdominal wall hernia repair, BMI > 34, heavy weight bearing job/hobby, and/or emergent repair.

RESULTS

Hiatal hernia repair with magnetic sphincter augmentation was performed on 137 patients. The HRHR group (N = 86) and the LRHR group (N = 51) were compared and there was a difference observed with acute hernia recurrence, dysphagia (p value = 0.008), and number of post-op EGDs (p value = 0.005) in favor of the HRHR group. Other postoperative variables observed (i.e., length of stay and PPI use) showed no significant difference between the two groups.

CONCLUSIONS

Fundic gastropexy for individuals who are considered high risk for recurrence does not appear to alter the perioperative course in our sample of patients. The HRHR group has the same length of stay experience and improved postoperative outcomes with reference to postoperative EGD, dysphagia and a decreasing trend in hiatal hernia recurrence.

Minding the Gap: Clinical Manifestations of a Rare Type IV Hiatal Hernia

Hiatal hernias are classified according to the increasing severity of protruding intra-abdominal viscera through the esophageal hiatus (types I-IV). Herein is the case of an elderly patient presenting with recent-onset dyspnea, postprandial gastroesophageal reflux, and hypoxemia. Imaging revealed a rare type IV hiatal hernia implicating the stomach and part of the pancreas. This case highlights the seemingly benign clinical manifestations of a massive hiatal hernia, despite its ability to complicate treatment or exacerbate comorbid conditions.

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.

The management of hiatal hernia: an update on diagnosis and treatment

BACKGROUND AND AIM

Hiatal hernia (HH) occurs quite frequently in the general population and is characterized by a wide range of non-specific symptoms, most of them related to gastroesophageal reflux disease. Treatment can be challenging at times, depending on the existence of complications. The most recent guideline regarding the management of hiatal hernia was released by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) in the year 2013. This review aims to present the most recent updates on the diagnosis and management of hiatal hernia for clinical practitioners.

METHODS

The PubMed database was screened for publications using the terms: "hiatal hernia", "paraesophageal hernia", "management", "treatment", "hiatal repair". A literature review of contemporary and latest studies was completed. The studies that we looked into include prospective, randomized trials, systematic reviews, clinical reviews and original articles. The information was compiled in narrative review format.

RESULTS

This narrative review presents new data on the diagnosis and management of hiatal hernia. While the diagnostic pathway has remained virtually unchanged, new data have come to light regarding the surgical treatment of hiatal hernia. We present the imaging methods used for its diagnosis, as well as the medical and surgical treatment currently available.

CONCLUSION

In the last five years, there has been vast research in the field of hiatal hernia management, especially regarding the surgical treatment. However, unanswered questions still remain and solid updates on the guidelines have yet to be formulated. To address this, more randomized studies need to be done on subsets of patients, stratified by age, gender, symptoms and comorbidities.

Role of fundoplication in treatment of patients with symptoms of hiatal hernia

Gastroesophageal reflux disease (GERD) is often associated with hiatal hernia (HH). However, the need for fundoplication during hiatal hernia repair (HHR) remains controversial. The objective of this study was to evaluate the effect of HHR with concomitant laparoscopic Nissen fundoplication (HHR-LNF) in HH patients. A total of 122 patients with symptomatic HH were randomized to receive either HHR (n = 61) or HHR-LNF (n = 61). The measures of evaluating outcomes included DeMeester scores (DMS), complications, Reflux Diagnostic Questionnaire and patients' satisfaction 24 months following surgery. Despite comparable values in both groups at randomization, the DMS, total numbers of reflux episodes and percentage of time with pH < 4 were significantly higher in HHR group than in HHR-LNF group (P = 0.017, P = 0.002 and P = 0.019, respectively) at 6 months after surgery. One months postoperatively, complications were higher in the HHR-LNF group than in the HHR group (all P < 0.001), and there was no difference between the two groups at 6 months. By the end of the 2-year follow-up, HHR-LNF group showed a significantly lower reflux syndrome frequency-intensity score and greater percentage of satisfaction compared with HHR group (all P < 0.001). Laparoscopic HHR should be combined with a fundoplication in GERD patients with HH. HHR-LNF is safe and effective, not only improve reflux-related symptom, but also reduce the incidence of complications.

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.

Treatment of paraesophageal hiatal hernia in octogenarians: a systematic review and retrospective cohort study

Over the coming years octogenarians will make up an increasingly large proportion of the population. With the rise in octogenarians more paraesophageal hiatal hernias may be identified. In research for the optimal treatment for paraesophageal hiatal hernias, octogenarians are often omitted and the optimal surgical strategy for this patient group remains unclear. A systematic search in PubMed, Embase, and The Cochrane Library was conducted, including articles compromising 'surgery,' 'paraesophageal hiatal hernia,' and 'octogenarians.' Selection of articles was based on independent review by two authors. Alongside, a retrospective cohort study was conducted including all type II-IV hiatal hernia repairs performed in the VU Medical Center in Amsterdam, The Netherlands, from 2005 to 2015. A total of 486 papers were eligible for selection. After careful selection, a total of eight articles were included. All articles were retrospective cohort studies describing different proportions of octogenarians. The populations and surgical techniques were very heterogeneous. Elective paraesophageal hiatal hernia repair was performed safely in symptomatic octogenarians in all studies. Additional analysis of 84 patients, of which 9.5% octogenarians, was performed at our tertiary referral center. A larger hernia type, more acute interventions and a higher morbidity and mortality rate was observed in octogenarians compared to patients aged <80 years. In conclusion, elective paraesophageal hiatal hernia repair can be performed in octogenarians, especially in patients without comorbidity. Findings suggest improvement in symptoms in short-term follow up, with minimal morbidity and mortality. With regard to surgical techniques, laparoscopy and fundoplication were performed safely. Octogenarians need to be included in future clinical trials to further evaluate the optimal surgical intervention. Preoperative risk assessment by clinical prediction rules should guide operative intervention, in order to evaluate risks and benefits in this challenging population.

Clinical Manifestations of Huge Diaphragmatic Hernias

Translocation of abdominal organs into the thoracic cavity may cause dyspnea, heart disorders, and gastric symptoms. Diaphragmatic hernias can cause diagnostic difficulties, since both clinical and radiological symptoms might imitate different disorders. In these cases computed tomography of the chest is the method of choice. The aim of this study was to assess clinical manifestations, risk factors, and prognosis in patients with huge diaphragmatic hernias with displacement of abdominal organs into the thorax, depending on the action taken. We carried out a retrospective study using data of patients hospitalized in the years 2012-2016. Ten patients were qualified for the study (8 women and 2 men). The mean age of the subjects was 86.5 ± 10.5 years. Thirty percent of the hernias were post-traumatic. All of the patients reported cardiovascular or respiratory symptoms. Upper gastrointestinal symptoms occurred in half of the patients. Twenty percent of patients underwent surgery with a positive outcome, while 30% of patients, who were not qualified for surgery due to numerous co-morbidities, died. The main risk factors predisposing to the occurrence of large diaphragmatic hernias were the following: old age, female gender, and thoracic cage deformities.

Primary and Redo Antireflux Surgery: Outcomes and Lessons Learned

INTRODUCTION

Some patients require one or more reoperative interventions after undergoing primary antireflux surgery (ARS). We compared outcomes after primary and reoperative ARS.

METHODS

We queried a prospectively maintained database to identify patients who underwent ARS from September 23, 2003 to May 28, 2016. Patients were categorized into four groups: A (primary ARS), B (first reoperative ARS), C (second reoperative ARS), or D (≥ third reoperative ARS). Patients completed follow-up foregut symptom surveys and satisfaction questionnaires at regular intervals.

RESULTS

In total, 940 patients were studied (A: n = 545, B: n = 302, C: n = 80, D: n = 13). Age, sex, and BMI were comparable across groups. Heartburn was the most common preoperative symptom in A, whereas dysphagia was more common in B-D. Open approach, mean operative time, and mean blood loss increased from A to D (P < 0.05), as did need for Roux-en-Y reconstruction. Vagal injury (2-19-33-54%; P < 0.05), visceral perforation (2-20-36-23%; P < 0.05), postoperative leak (0.2-2-6-8%; P < 0.05 A vs. all), and morbidity (2-10-14-39%; P < 0.05) also increased from A to D. At mean follow-up of 36 months, the proportion of patients who reported no significant symptoms, excellent satisfaction, and likeliness to recommend this surgery to a friend progressively declined with each successive reintervention (P < 0.05).

CONCLUSIONS

Complications and patient-reported outcomes worsen with each reoperative ARS.

Laparoscopic repair of giant paraesophageal hernia: are there factors associated with anatomic recurrence?

BACKGROUND

Repair of giant paraesophageal hernia (PEH) is associated with a favorably high rate of symptom improvement; however, rates of recurrence by objective measures remain high. Herein we analyze our experience with laparoscopic giant PEH repair to determine what factors if any can predict anatomic recurrence.

METHODS

We prospectively collected data on PEH characteristics, variations in operative techniques, and surgeon factors for 595 patients undergoing laparoscopic PEH repair from 2008 to 2015. Upper GI study was performed at 6 months postoperatively and selectively thereafter-any supra-diaphragmatic stomach was considered hiatal hernia recurrence. Exclusion criteria included revisional operation (22.4%), size <5 cm (17.6%), inadequate follow-up (17.8%), and confounding concurrent operations (6.9%). Inclusion criteria were met by 202 patients (31% male, median age 71 years, and median BMI 28.7).

RESULTS

At a median follow-up of 6 months (IQR 6-12), overall anatomic recurrence rate was 34.2%. Symptom recurrence rate was 9.9% and revisional operation was required in ten patients (4.9%). Neither patient demographics nor PEH characteristics (size, presence of Cameron erosions, esophagitis, or Barrett's) correlated with anatomic recurrence. Technical factors at operation (mobilized intra-abdominal length of esophagus, Collis gastroplasty, number of anterior/posterior stitches, use of crural buttress, use of pledgeted or mattress sutures, or gastrostomy) were also not correlated with recurrence. Regarding surgeon factors, annual volume of fewer than ten cases per year was associated with increased risk of anatomic failure (54 vs 33%, P = 0.02). Multivariate analysis identified surgeon experience (<10 cases per year) as an independent factor associated with early hiatal hernia recurrence (OR 3.7, 95% CI 1.34-10.9).

CONCLUSIONS

Laparoscopic repair of giant PEH is associated with high anatomic recurrence rate but excellent symptom control. PEH characteristics and technical operative variables do not appear to significantly affect rates of recurrence. In contrast, surgeon volume does appear to contribute significantly to durability of repair.

Spontaneous chylous ascites, chylomediastinum and bilateral chylothoraces encountered during laparoscopic incarcerated paraesophageal hernia repair

Chylous ascites is an accumulation of milky lipid-rich lymph in the peritoneal cavity. Spontaneous chyle leak is a rare occurrence, often associated with malignancy or cirrhosis. This is a report of spontaneous chylous ascites, chylomediastinum and chylothoraces encountered in the setting of an incarcerated paraesophageal hernia. A 60-year-old female presented to the emergency department with epigastric pain, dysphagia and vomiting. Clinical presentation and imaging were concerning for an incarcerated paraesophageal hernia, and the patient was taken to the operating room. During laparoscopic reduction of the hernia and repair, chyle was encountered in the peritoneal cavity, mediastinum and pleural spaces. Postoperatively, the chyle leak resolved with a nonfat diet. The unusual occurrence of a chyle leak in this case may have been due to compression of the thoracic duct within the chest by the incarcerated paraesophageal hernia.

It Is Not Always the Pulmonary Embolism

One of the leading reasons for emergency department visits happens to be chest pain and shortness of breath with estimated 6.3 million visits for chest pain and 3 million visits for shortness of breath. Over the years, there has been an upward trend in these demographics. The primary workup is usually toward cardio pulmonary causes. Paraesophageal hernia is a term to describe the herniation of gastroesophageal junction and the gastric fundus through the paraesophageal membrane. Paraesophageal hernias account for 5% of all the hiatal hernias, and patients are usually asymptomatic or have complaints of gastroesophageal reflux. However, on rare occasions, they are notorious to develop complications such as incarceration, gangrene, obstruction of intrathoracic stomach, collapse of the lung, and even death. We take this opportunity to present a 49-year-old man who presented with shortness of breath and chest pain. The initial workup revealed a pulmonary embolism on a computerized tomography scan. However, with better clinical judgment and more imaging, he was diagnosed with a paraesophageal hernia with gastric obstruction and early strangulation causing his symptoms.

Transthoracic repair of paraesophageal diaphragmatic hernia presenting with symptoms mimicking cardiac disease (chest pain and breathlessness)

We discuss a case of 60-year-old female patient, who presented with history of chest pain radiating to left shoulder, breathlessness and postprandial discomfort. Patient was initially suspected to be suffering from cardiac pathology and was evaluated accordingly. Upper gastrointestinal endoscopy also missed the findings of paraesophageal hernia as the gastroesophageal junction was at its normal position. Chest roentgenogram raised the suspicion of diaphragmatic hernia, computed tomogram of chest and abdomen was done later on and showed characteristic features of paraesophageal hernia. Patient underwent transthoracic repair of the paraesophageal hernia along with partial fundoplication and had complete relief from the symptoms after surgery.

Contemporary management of paraesophaegeal hernias: establishing a European expert consensus

BACKGROUND

The surgical treatment of paraesophageal hernias remains a challenge due to the lack of consensus regarding principles of operative treatment. The objectives of this study were to achieve consensus on key topics through expert opinion using a Delphi methodology.

METHODS

A Delphi survey combined with a face-to-face meeting was conducted. A panel of European experts in foregut surgery from high-volume centres generated items in the first survey round. In subsequent rounds, the panel rated agreement with statements on a 5-point Likert-type scale. Internal consistency (consensus) was predefined as Cronbach's α > .80. Items that >70 % of the panel either rated as irrelevant/unimportant, or relevant/important were selected as consensus items, while topics that did not reach this cut-off were termed "undecided/controversial".

RESULTS

Three survey rounds were completed: 19 experts from 10 countries completed round one, 18 continued through rounds two and three. Internal consistency was high in rounds two and three (α > .90). Fifty-eight additional/revised items derived from comments and free-text entries were included in round three. In total, 118 items were rated; consensus agreement was achieved for 70 of these. Examples of consensus topics are the relevance of the disease profile for assessing surgical urgency and complexity, the role of clinical history as the mainstay of patient follow-up, indications for revision surgery, and training and credentialing recommendations. Topics with the most "undecided/controversial" items were follow-up, postoperative care and surgical technique.

CONCLUSIONS

This Delphi study achieved expert consensus on key topics in the operative management of paraesophageal hernias, providing an overview of the current opinion among European foregut surgeons. Moreover, areas with substantial variability in opinions were identified reflecting the current lack of empirical evidence and opportunities for future research.

Current readings: Failed hiatal hernia repair

Recurrent hiatal hernia is noted in up to 70% of patients undergoing reoperative antireflux procedure. Role of short esophagus vis-à-vis a need for Collis gastroplasty, mesh reinforcement of hiatus, and access of surgery (thoracotomy vs laparotomy) have been debated. The aim of this article is to review selected recent publications that address these issues.
