Impact of Paraesophageal Hernia Repair on Respiratory Function: A Systematic Review

Background and Objectives: Surgical repair of hiatal and paraesophageal hernia is widely accepted for the treatment of gastroesophageal reflux symptoms. The respiratory benefit of this surgery is less clear. The objective of this review is to quantify the benefit to pulmonary function and subjective dyspnea of paraesophageal hernia repair with the aim of refining the indications and contraindications for elective paraesophageal hernia repair.Methods: Articles were gathered from systematic searches of the Medline Complete Database via the Creighton University Health Sciences Library literature search services. Publications with both pre and postoperative pulmonary function data or both pre and postoperative subjective dyspnea data with regards to surgical paraesophageal hernia repair were included.Results: Six studies were included in this review. The majority of studies in this review show improvement in pulmonary function postoperatively with regards to FEV1, FVC, and VC when stratified by % intrathoracic stomach (ITS), particularly in groups >50% ITS. No significant change was seen in postoperative DLCO or FEV1/FVC.Conclusion: Paraesophageal hernia repair has shown to improve pulmonary function both objectively and subjectively. This review was limited by the paucity of literature on the subject as well as the lack of a standardized method for measurement of %ITS.

Cervicothoracic Neurenteric Cyst With Contralateral Diaphragmatic Hernia: An Unusual Combination

We describe a premature male infant who died from complications resulting from two malformations: a large left-sided diaphragmatic hernia and a right-sided cervicothoracic neurenteric cyst. The findings of the first limited prenatal ultrasound led to the incorrect diagnosis of right-sided diaphragmatic hernia. Vertebral anomalies, commonly associated with neurenteric cysts, and an intrathoracic stomach, were not identified until autopsy examination. A literature review describes only one partly similar case relating a neurenteric cyst to the jejunum associated with an ipsilateral diaphragmatic defect identified on prenatal ultrasound. The second report of this combination raises the question of a developmental relationship.

A128 ACUTE GASTRIC VOLVULUS DISGUISED AS ACUTE CORONARY SYNDROME.

Background Acute gastric volvulus is a rare but potentially life-threatening condition that warrants emergent assessment. Its clinical presentation may encompass the Borchardt’s triad of vomiting, epigastric pain, and inability to insert a nasogastric tube. However, it can also present as chest pain and is often not cited within the typical differential diagnosis of non-cardiac causes of chest pain. We report the first known case of mesenterico-axial gastric volvulus presenting as acute coronary syndrome with a normal electrocardiogram, complete with radiographic and endoscopic images. Aims To present a case of acute gastric volvulus disguised as an acute coronary syndrome and describe its management. Methods Case report and review of literature. Results A 68 year-old female with history of recent coronary artery bypass graft surgery presented to hospital with sudden onset chest pain radiating to her left shoulder and jaw while having dinner. Initial high sensitivity troponin (normal <9ng/L) was 15ng/L, which increased to a modest peak at 115ng/L. ECG at presentation and through admission consistently showed normal sinus rhythm x 5. She was assessed by Cardiology and given her rising troponin and chest pain, she was treated as a non-ST elevation myocardial infarction with dual antiplatelet therapy. She underwent cardiac catheterization showing distal graft anastomotic site stenosis and was stented x2. Post procedure, her severe retrosternal chest pain recurred. GI was consulted for dysphagia and odynophagia, which was then noted to be present concurrent with her initial chest pain presentation. An urgent CT scan of the abdomen and pelvis revealed acute mesenterico-axial gastric volvulus (Figure 1A), a rarer form of gastric volvulus in the adult population compared to its organo-axial counterpart. After a failed nasogastric decompression, an emergent upper endoscopy was attempted and demonstrated mucosal necrosis (Figure 1B) but was unsuccessful in relieving the volvulus. The patient then underwent overnight surgery, which showed gastric volvulus with contained perforation and 50% necrosis of the stomach with sparing of the cardia and antrum. This resulted in a subtotal gastrectomy, hiatus hernia repair, pyloromyotomy, jejunostomy, and bilateral chest tube insertion. She then recovered in ICU before being successfully discharged home from hospital. Conclusions Acute gastric volvulus can present while disguised as more common causes of chest pain, such as acute coronary syndrome. Those who present with chest pain who also have a history of a large hiatal hernia, or an intrathoracic stomach should be evaluated with gastric volvulus in the differential diagnosis as its prompt management is critical to reduce morbidity and mortality.

Postoperative gastric Outlet Obstruction following hiatal hernia repair in an infant: A case report

Background: Infantile hypertrophic pyloric stenosis (IHPS) is an exceedingly rare cause of postoperative emesis in a case of hiatal hernia. Occasionally it may simulate other etiology of gastric outlet obstruction. Case Presentation: A 32-day-old male baby presented with respiratory distress and vomiting since birth. Diagnosis of eventration of left hemi diaphragm was made on CT Chest. At surgery, hiatal hernia with an intrathoracic stomach was found, which was repaired. On 5th postoperative day, the baby developed vomiting after feeding which gradually turned to be projectile in nature over a week. Contrast meal performed showed malpositioned stomach with delayed emptying. At re-operation, a well-formed olive of pylorus was encountered; Ramstedt pyloromyotomy was done. Postoperative course remained uneventful. Conclusion: IHPS is a rarely described association with hiatal hernia. Pyloric stenosis should be considered in differential diagnoses of postoperative emesis in infants with hiatal hernia.

Duodenal displacement and acquired intrathoracic stomach in an extreme premature baby on jejunostomy feeds- a case report

Repeated and persistent displacement forces can lead to acquired abnormalities in the position of the foregut in premature neonates. Cow milk protein intolerance should be considered early as a cause of feed intolerance, recurrent vomiting and other gastrointestinal symptoms in premature neonates. Upper gastrointestinal contrast study cannot be used to diagnose gastro-oesophageal reflux disease.
