Minimally invasive surgery for large hiatal hernia

Incarceration of a part of the gastric wall into the abdominal cavity in a patient with hiatal hernia and complete dislocation of the stomach (upside-down stomach)

An upside-down stomach is a rare type of hiatal hernia. An 83-year-old woman presented to the emergency room with abdominal pain and vomiting. Computed tomography revealed an upside-down stomach and the incarceration of a part of the gastric body into the abdominal cavity. Upper gastrointestinal endoscopy revealed a circular ulcer caused by gastric ischemia. Although she was discharged after 1 week of conservative therapy, she was readmitted to the hospital 1 day after discharge because of a recurrence of hiatal hernia incarceration. She underwent laparoscopic surgery 4 days after readmission and recovered successfully.

Functional results after hiatal repair and gastropexy without fundoplication in patients with paraoesophageal hernia

PURPOSE

Paraoesophageal hernias (PEH) are associated with a high complication rate and often occur in elderly and fragile patients. Surgical gastropexy without fundoplication is an accepted alternative procedure; however, outcomes and functional results are rarely described. Our study aims to evaluate short-term outcomes and the long-term quality of life after gastropexy as treatment for PEH.

METHODS

Single center cohort analysis of all consecutive patients who underwent gastropexy for PEH without fundoplication. Postoperative outcomes and functional results were retrospectively collected. Reflux symptoms developed postoperatively were reported using the validated quality of life questionnaire: GERD-Health Related Quality of Life Qestionnaire (GERD-HRQL).

RESULTS

Thirty patients (median age: 72 years (65-80)) were included, 40% classified as ASA III. Main PEH symptoms were reflux (63%), abdominal/thoracic pain (47%), pyrosis (33%), anorexia (30%), and food blockage (26%). Twenty-six laparoscopies were performed (86%). Major complications (III-IVb) occurred in 9 patients (30%). Seven patients (23%) had PEH recurrence, all re-operated, performing a new gastropexy. Median follow-up was 38 (17-50) months. Twenty-two patients (75%) reported symptoms resolution with median GERD-HRQL scale of 4 (1-6). 72% (n = 21) reported operation satisfaction. GERD-HRQL was comparable between patients who were re-operated for recurrence and others: 5 (2-19) versus 3 (0-6), p = 0.100.

CONCLUSION

Gastropexy without fundoplication was performed by laparoscopy in most cases with acceptable complications rates. Two-thirds of patients reported symptoms resolution, and long-term quality-of-live associated to reflux symptoms is good. Although the rate of PEH recurrence requiring a new re-intervention remained increased (23%), it does not seem to affect long-term functional results.

Is it meaningful to add mesh reinforcement to laparoscopic fundoplication for esophageal hiatal hernias in the patients with high risk of hiatal hernia recurrence?

BACKGROUND

While laparoscopic fundoplication is a standard surgical procedure for patients with esophageal hiatal hernias, the postoperative recurrence of esophageal hiatal hernias is a problem for patients with giant hernias, elderly patients, or obese patients. Although there are some reports indicating that reinforcement with mesh is effective, there are differing opinions regarding the use thereof. The aim of this study is to investigate whether mesh reinforcement is effective for laparoscopic fundoplication in patients with esophageal hiatus hernias.

METHODS

The subjects included 280 patients who underwent laparoscopic fundoplication as the initial surgery for giant esophageal hiatal hernias, elderly patients aged 75 years or older, and obese patients with a BMI of 28 or higher, who were considered at risk of recurrent hiatal hernias based on the previous reports. Of the subject patients, 91 cases without mesh and 86 cases following the stabilization of mesh use were extracted to compare the postoperative course including the pathology, symptom scores, surgical outcome, and recurrence of esophageal hiatus hernias.

RESULTS

The preoperative conditions indicated that the degree of esophageal hiatal hernias was high in the mesh group (p = 0.0001), while the preoperative symptoms indicated that the score of heartburn was high in the non-mesh group (p = 0.0287). Although the surgical results indicated that the mesh group underwent a longer operation time (p < 0.0001) and a higher frequency of intraoperative complications (p = 0.037), the rate of recurrence of esophageal hiatal hernia was significantly low (p = 0.049), with the rate of postoperative reflux esophagitis also tending to be low (p = 0.083).

CONCLUSIONS

Mesh reinforcement in laparoscopic fundoplication for esophageal hiatal hernias contributes to preventing the recurrence of esophageal hiatal hernias when it comes to patient options based on these criteria.

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.

The pathological conditions and surgical outcomes depending on the degree of hernia in the intra-thoracic stomach

BACKGROUND

In recent years, the number of patients requiring surgery for intra-thoracic stomach (ITS) has been increasing due to the effects of obesity and gibbus due to aging. The aim of this study is to assess the effects of the degree of hernia on the pathological conditions and surgical outcomes in ITS patients.

METHODS

ITS was defined as cases in which over 50% of the stomach had deviated into the mediastinum by esophagogastric fluoroscopy and/or computed tomography, with 65 patients who underwent laparoscopic surgery as the initial surgery included. We compared the pathological conditions and surgical outcomes by dividing the subjects into 3 groups: Group A: 50%- < 75%; Group B: 75%- < 100%; and Group C: 100% (upside-down stomach), depending on the degree of deviation into the mediastinum of the stomach.

RESULTS

The breakdown of patients was 33 in Group A, 21 in Group B, and 11 in Group C. Regarding the preoperative pathological conditions, Group C had a high body mass index (BMI) and a low score for factor V according to upper gastrointestinal endoscopy (p = 0.0109, p = 0.0062, respectively). While the surgical results indicated that the operation time was extended depending on the degree of hernia (p = 0.0051), there was no marked difference in other surgical outcomes or the postoperative course among the three groups, with a high degree of satisfaction.

CONCLUSIONS

In the case of ITS, although the operation time was extended depending on the degree of the hernia, the surgical outcomes were the same, and overall good results were obtained.

A new technique for treating hiatal hernia with gastroesophageal reflux disease: the laparoscopic total left-side surgical approach

Introduction

Although the traditional bilateral surgical approach to treat hiatal hernia (HH) with gastroesophageal reflux disease (GERD) can provide local protection of the vagus nerve, the integrity of the entire vagus nerve cannot be evaluated. Therefore, we developed and described the total left-side surgical approach (TLSA), which theoretically reduces injury to the vagus nerve, and described the detailed surgical procedure.

Methods

Initially, we performed a cadaver study to explore the characteristics of the vagus nerve. Then, we prospectively evaluated the TLSA in 5 patients with HH and GERD between June 2020 and September 2020. Demographic characteristics, surgical parameters, perioperative outcomes, and follow-up findings were analyzed.

Results

The TLSA was successfully used in five patients (40–64 years old), and no major complications were noted. The median total operative time was 114 min, median blood loss was 50 mL, and median postoperative hospital stay was 3.8 days. Gastrointestinal function recovered within 4 days of surgery in all the patients. The 6-month follow-up gastroscopy examination showed well-established gastroesophageal flap valves. Compared with the baseline results, the 6-month follow-up results showed lower values for the total GerdQ score (12.4 vs. 6.2) and the total esophageal acid exposure time (3.48% vs. 0.38%). Based on the European Organization for Research and Treatment of Cancer quality of life questionnaire-stomach module 52 results, the incidence of dysphagia and flatulence decreased over time after the TLSA.

Conclusions

The TLSA provides a clear and broad surgical field, less trauma, and rapid recovery; moreover, it is technically simple. Although our results suggest that the TLSA provides safety and short-term efficacy and is feasible for patients with HH and GERD, long-term results from a larger clinical trial are needed to validate these findings.

Treatment strategy for laparoscopic hiatal hernia repair

INTRODUCTION

According to the anatomy-function-pathology classification, the recurrence rates of A2 and A3 hiatal hernia (HH) after laparoscopic fundoplication are higher than the rate of A1 HH. Therefore, we introduced mesh reinforcement for A2 and A3 cases. In addition, gastropexy was added to A3 cases. We present the strategy for HH repair.

METHODS

In all, 537 patients (mean age 55.4 ± 16.7 years, 219 women) who underwent primary laparoscopic fundoplication for HH from January 1995 to October 2019 were included. They were divided into three groups by A factor (A1:A2:A3 = 296:156:85). Their clinical data were collected in a prospective fashion and retrospectively reviewed.

RESULTS

The median age (years) of the patients in each group was A1:A2:A3 = 46:63:74 years, and age was directly proportional to the size of HH (P < 0.0001). The proportion of females was significantly higher in A3 than in other classes (P < 0.0001). Preoperative reflux esophagitis was severe in A2 (P < 0.0001) and operation time (min) was directly proportional to HH size (A1:A2:A3 = 135:167:193, P < 0.0001). The recurrence rate of conventional laparoscopic fundoplication was 15% (46/304), and it was higher for A2 and A3 than for A1 (P = 0.027). However, with reinforcement of the hiatus using a mesh and gastropexy, the recurrence rates decreased.

CONCLUSION

Combining mesh reinforcement and gastropexy may reduce the recurrence rate of para- and mixed-type HH.

Therapeutic effect of laparoscopic fundoplication for GERD-related disease in the elderly

BACKGROUND

It is anticipated that surgical treatment for gastro-esophageal reflux disease (GERD) in the elderly will increase. This time, using propensity score matching, we examined the results of laparoscopic fundoplication (LF) for GERD-related diseases in the elderly.

METHODS

Of 302 cases which underwent initial LF for GERD-related diseases during the period from June 2008 to February 2019, we classified them into elderly (65 years of age or older) and non-elderly groups (64 years of age or younger). 57 cases each were extracted upon performing propensity score matching regarding five factors including: gender; body mass index; esophageal hiatal hernia; extent of reflux esophagitis; and the use of mesh.

RESULTS

With regard to the preoperative disease status, the pH < 4 holding time was indicated as 2.8% (0.5-10.7%) in the elderly group and 3.4% (0.6-8.0%) in the non-elderly group, with no difference in terms of the illness period as well (p = 0.889 and p = 0.263, respectively). Although there was no difference in terms of the operative time (155 vs. 139 min, p = 0.092) and estimated blood loss (both ≒ 0 ml, p = 0.298), postoperative hospital stay was prolonged in the elderly group [7 (7-9) vs. 7 (7-7), p = 0.007]. On the other hand, esophageal hiatal hernia, reflux esophagitis, and acid reflux time in the esophagus were all improved following surgery in both groups (p < 0.001 in both groups).

CONCLUSION

The treatment results of LF for GERD-related diseases in the elderly were as good as those in the non-elderly, indicating possible safe implementation.

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.

Outcomes after Laparoscopic Gastropexy as an Alternative for Paraesophageal Hernia Repair

Background:

Outcomes after laparoscopic gastropexy (LG), performed as an alternative to formal paraesophageal hernia (PEH) repair in patients with giant PEH, have been rarely studied. This manuscript evaluates complications and long-term quality-of-life after LG.

Methods:

An IRB-approved protocol was used to identify patients who underwent LG to alleviate symptoms of acute or chronic gastric obstruction secondary to a paraesophageal hernia. Postoperative outcomes and quality-of-life data were retrospectively collected via chart review and prospectively via phone interview.

Results:

Twenty-six patients underwent LG, with a median age of 76 (52 – 91). Median follow-up was 28 (3 to 55) months. Gastropexy was the chosen intervention due to comorbid conditions (23, 88%), gastric inflammation (2, 8%), or intraoperative instability (1, 4%). Nine (35%) suffered postoperative complications, and 2 (8%) required reoperation. At the time of follow-up, 7 (27%) had died, 3 (11%) could not be reached. Sixteen (62%) completed the follow-up survey. Fourteen (88%) reported symptom resolution. Ten (62%) still required antireflux medication. Median Gastroesophageal Reflux Disease-Health Related Quality of Life score was 4.5 (0 to 19). Fourteen (88%) denied current dietary restrictions. All reported satisfaction with the operation.

Conclusion:

Laparoscopic PEH repair remains the standard of care for the management of giant PEH. However, a subcategory of patients with high operative risk could be candidates for a shorter operative intervention. As our data infers, LG is a reasonable alternative in this patient population. While the continued use of antisecretory medications is sometimes required, LG restores the ability to tolerate full meals without restrictions and results in excellent patient satisfaction.

Factors affecting the treatment outcomes of laparoscopic fundoplication for erosive reflux esophagitis: findings of esophageal pathological function tests

PURPOSE

To identify the factors that affect laparoscopic fundoplication (LF) treatment efficacy in patients with erosive gastroesophageal reflux disease (e-GERD) esophagitis, based on the findings of multichannel intraluminal impedance pH (MII-pH) and high-resolution manometry (HRM).

METHODS

The subjects were 102 patients with e-GERD diagnosed by endoscopy, who underwent LF as the initial surgery. To analyze the findings of MII-pH and HRM, the patients were divided into two groups: a cured group (CR), comprised of patients whose esophagitis was cured postoperatively; and a recurrence group (RE), comprised of patients who suffered recurrent esophagitis.

RESULTS

There were 96 patients in the CR group and 6 in the RE group. MII-pH indicated that the acid reflux time, the longest reflux time, and the number of refluxes longer than 5 min, were significantly higher in the RE group than in the CR group (p = 0.0028, p = 0.0008, p = 0.012, respectively). The HRM indicated that only the distal contractile integral (DCI) was significantly lower in the RE group (p = 0.0109).

CONCLUSION

The results of this study indicate that esophageal clearance may affect the treatment outcome of LF. Based on the findings of MII-pH, the longest reflux time and the number of refluxes longer than 5 min were important factors influencing the therapeutic effect, whereas based on the HRM, the DCI value was most important.

Chest Pain: A Relatively Benign Symptom of Type IV Hiatal Hernia

Hiatal hernia results from the translocation of intra-abdominal contents from their usual position into the thorax. They can be categorized into type I-IV which implies varying gradations of herniation. The symptomatology can range from just chest pain in the less severe types to respiratory and hemodynamic compromise resulting from strangulation in the advanced hernias. Our patient was an 81-year-old female with a past medical history of gastroesophageal reflux disease (GERD), deep venous thrombosis (DVT), hypertension, hyperlipidemia, coronary artery disease (CAD), and cerebrovascular accident (CVA), who presented to the emergency department (ED) with the chief complaint of chest pain. Assessment of the vitals in the ED revealed a temperature of 37.2 °C, respiratory rate of 18 breaths/minute with an oxygen saturation of 100% on room air, heart rate of 95 beats/min, and blood pressure reading of 132/110 mmHg. Due to significant concern of a possible coronary pathology leading to chest pain, the patient was given 325 mg of aspirin and one tablet of sublingual nitroglycerin. Her electrocardiogram (EKG) was unremarkable but the chest X-ray revealed a large retrocardiac hernia. The finding was corroborated after a review of the computerized tomography (CT) scan performed at the outlying facility. She was treated with omeprazole, a gastroenterologist was consulted, and an esophagogastroduodenoscopy (EGD) performed which revealed significant erosions in the distal esophagus and gastric antrum. She was deemed a high-risk surgical candidate for any intervention and thus managed conservatively with proton pump inhibitor (PPI) therapy. The case highlights the pertinent facts about hiatal hernia. Although the diagnosis of chest pain with the aforementioned comorbidities could be skewed towards coronary pathology, keeping a wide differential is important so that the right diagnosis can be made in a timely fashion and complications avoided.

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.
