Cardiopulmonary Impairments Caused by a Large Hiatal Hernia with Organoaxial Gastric Volvulus Showing Upside-Down Stomach: A Case Report

Sigmoid Volvulus in the Setting of Type 4 Hiatal Hernia: An Uncommon Presentation and Literature Review

Hiatal hernias occur when intra-abdominal contents protrude into the diaphragmatic opening. Of the four classifications, Type 4 hiatal hernias are the most rare and severe. They develop from herniation of the gastroesophageal junction and abdominal viscera other than the stomach into the thoracic cavity. The resulting increase in intrathoracic pressure can cause a wide variety of symptoms on presentation and potentially lead to misdiagnosis. We present a rare case in which a 78-year-old woman presented with nonspecific symptoms and was diagnosed with incarcerated Type 4 hiatal hernia with sigmoid volvulus. We also report a literature review from 2015 to emphasize the importance of recognizing diverse symptomatic presentations in complex Type 4 hiatal hernias and the need for a comprehensive evaluation, as early detection and prompt intervention are essential in preventing life-threatening complications.

The cardiovascular effects of large hiatal hernias: a narrative review of cases and studies

Hiatal hernia (HH) is a common disease in the general population. It is often asymptomatic, but if it does present clinical manifestations, these are usually gastrointestinal. Gastroesophageal reflux is the main symptom that accompanies it. Depending on the severity of the hernia, it is classified into several subtypes from I-IV. Especially, IV type (giant HH) can lead to various cardiopulmonary symptoms with several degrees of severity. It is necessary to keep this possibility in mind among the various differential diagnoses that may occur in this clinical setting. The current paper aims to review the literature on classic and novel information on the HH - cardiovascular system relationship. Epidemiological data, physiological aspects of the heart compressed by HH, cardiovascular symptoms, electrocardiographic changes, echocardiographic alterations and clinical implications are discussed.

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.

‘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.

Paraesophageal hernia repair can decrease BNP levels

BACKGROUND

Although the main manifestation of giant paraesophageal hernia (PEH) is disordered meal passage due to gastric torsion, the contents of the hernia sometimes squeeze the heart and lungs and induce the symptoms of respiratory or heart failure. Furthermore, the quality of life (QOL) of patients with a heavy cardiac load deteriorates. In this study, changes in a heart failure marker and symptoms of cases with a giant PEH from before to after laparoscopic surgery were examined.

METHODS

Levels of brain natriuretic peptide (BNP) as a heart failure marker were measured before and after radical laparoscopic surgery in cases of type III, IV type of giant PEH. Changes of the symptoms due to heart failure were also investigated.

RESULTS

A total of 75 hiatal hernia surgeries were performed in 2012-2019. Of them, 50 had a giant PEH, and 20 (40.0%) had heart failure symptoms such as fatigue and exertional dyspnea. In the giant PEH cases, BNP could be measured before and after surgery to evaluate the presence of heart failure in 23 cases; postoperative BNP levels decreased from the preoperative values in 18 of them. Furthermore, in many cases, chest symptoms also improved.

CONCLUSIONS

Radical laparoscopic surgery can reduce heart failure due to giant PEH. Therefore, in addition to conventional surgical indication criteria such as vomiting and food loss, increased cardiac load may be added to the new surgical indication criteria.

Acute intrathoracic gastric volvulus with retrograde gastric intussusception: A case report of a rare surgical emergency with review of the literature

•

The acute intrathoracic gastric volvulus is a rare condition.

•

The gastrogastric intussusception is very very rare.

•

The gastric volvulus and the gastrogastric intussusception are surgical emergencies.

•

Any delay in diagnosis and treatment can prove fatal.

•

Emergent laparotomy or laparoscopy is considered the correct treatment.

Introduction

The gastric volvulus is a rare condition in which the stomach, or part of it, rotates on its axis, for over 180°, constituting a surgical emergency. Even more rare is gastro-gastric intussusception. A delay in their diagnosis and treatment can have fatal consequences

Presentation of case

An 82-year-old woman was admitted to the Surgery Unit with a two-day history of abdominal pain associated at first with coffee vomiting and, subsequently, with unproductive retching and oligoanuria. Physical examination showed severe dehydration, fever, at the abdominal level, palpation caused a marked tenderness of all quadrants, with signs of peritonism.

Laboratory test showed showed neutrophilic hyperleukocytosis and high C reactive protein level. Abdominal computed tomography revealed an acute intrathoracic gastric volvulus and a gastrogastric intussuception. The patient was submitted to exploratory laparotomy, subtotal gastrectomy with Roux en Y anastomosis and simple plastic of the esophageal hiatus. At the end of the surgery, however, the patient died of your septic shock.

Discussion

The traditional treatment for a patient with acute gastric volvulus is an immediate surgical intervention to derotate the stomach and prevent vascular insufficiency.

In the presence of necrosis or gastric perforation, resection should be performed.

The few cases of gastrogastric intussusception described in the literature have been treated with sub-total gastrectomy and gastro-jejunal anastomosis. Any delay in diagnosis and treatment can prove fatal.

Conclusion

Intrathoracic Gastric Volvulus and, even more, retrograde gastrointestinal intussusception are very rare pathologies, difficult to diagnose.
