Although the use of mesh reinforcement during large hiatal hernia repair may reduce the rate of recurrence, various mesh-related complications have been reported. A 65-year-old woman presented with dysphagia. The patient was diagnosed with a large hiatal hernia and treated with laparoscopic fundoplication and Collis gastroplasty with mesh repair. Six months after surgery, the patient presented with dysphagia and vomiting. Esophagogastroduodenoscopy showed migration of mesh material into the esophagogastric junction. We performed a proximal gastrectomy with mesh removal. The patient was discharged without any postoperative complications. Herein, we encountered a rare case requiring surgical treatment to resolve mesh-induced esophagogastric perforation after hiatal hernia repair. Mesh-associated complications, such as erosion or migration, should be considered as they may be more common than previously reported. Additionally, these complications are currently underscored in clinical practice. Regarding mesh applications, symptoms of mesh-related complications, such as dysphagia, should be carefully monitored for early detection.

Diaphragmatic hernias occur in up to 10%-50% of the general population. Treatment of hiatal hernias depends on the type of hernia and the severity of the symptoms. We report the case of a 52-year-old woman with no significant history who presented for 1 year with non-specific chest pain, dyspnea, dysphagia, and heartburn. A thoracoabdominal tomography with contrast was performed, showing a diaphragmatic hernia containing the stomach, portions of the duodenum, pancreas, small intestine, and colon with a sac of up to 20 cm, which was successfully repaired laparoscopically.

UNASSIGNED: Gastroesophageal reflux (GER) disease (GERD) is a condition wherein GER causes troublesome symptoms that can affect daily functioning and/or clinical complications within the esophagus or other systems. To avoid this, patients with GERD often require treatment; hence, it is important to distinguish GER from GERD. Patients with GERD exhibiting alarm signs should be examined early to differentiate it from GER and treated accordingly. Herein, we present a case of GERD caused by a hiatal hernia that required surgical intervention for esophagial cicatrical stenosis despite oral treatment. We also discussed how to choose the appropriate acid suppressants for GERD.
UNASSIGNED: A 1-year-old boy was referred to our hospital for repeated vomiting and poor weight gain. He received histamine 2 receptor antagonists (H2RAs) that contributed slightly to the decreased frequency of vomiting and aided weight gain; however, he soon stopped gaining weight and had bloody vomit. His upper gastrointestinal series revealed hiatal hernia, a 24 h impedance pH monitoring test indicated abnormal values for acid reflux, and esophagogastroduodenoscopy (EGD) revealed esophagitis. He was subsequently diagnosed with GERD associated with hiatal hernia. A proton pump inhibitor (PPI) was intravenously administered to him, following which his medication was changed to a potassium-competitive acid blocker (P-CAB). Thereafter, his vomiting episodes significantly decreased and his weight increased. However, 6 months after starting P-CAB, his vomiting episodes suddenly increased in frequency. EGD revealed the presence esophageal stricture due to scarring from GERD. He was then treated via laparoscopic fundoplication, gastrostomy, and esophageal balloon dilation. Thereafter, his vomiting episodes stopped and food intake improved, leading to weight gain.
UNASSIGNED: It is essential to identify the cause of GERD early and take an appropriate treatment approach depending on the cause of GERD with alarm signs. Further, as a drug therapy for GERD as a clear acid mediated disease or in children with alarm signs, PPIs or P-CAB should be used from the beginning instead of H2RAs.

Hiatal hernia is a gastrointestinal disorder characterized by abnormal displacement of a portion of the stomach into the thoracic cavity. It has multiple stages ranging from type I-IV according to severity. The more severe the hernia, the more likely it will produce symptoms, and it would be unlikely for it to be asymptomatic. In this case report, we describe a rare situation in which a 79-year-old woman\'s type IV hiatal hernia was incidentally found after she suffered a mechanical fall.

Congenital mixed hiatal hernia is a disorder that combines features of both sliding and paraoesophageal hernias. The precise incidence of congenital mixed hiatal hernia during the pediatric and neonatal period remains uncertain, making diagnosis challenging within this age cohort. This case presents a 15-day-old female with an 8% postnatal weight loss and apost-feeding vomiting. An upper gastrointestinal series, computer tomography, and upper endoscopy revealed a mixed hiatal hernia. The patient underwent a laparoscopic herniorrhaphy and Nissen fundoplication achieving successful resumption of complete oral feeding before discharge. Diagnosis and management of this condition in neonates remain challenging due to its rarity and variable clinical presentations. This report emphasizes the importance of early recognition, accurate diagnosis, and tailored management strategies in the neonatal period. Further research, with a collaborative effort between pediatricians and surgeons, is needed to refine diagnostic criteria, establish evidence-based management approaches, and improve outcomes for affected children.

BACKGROUND: Paraesophageal hernia repairs (PEHRs) have high rates of radiographic recurrence, with some patients requiring repeat operation. This study characterizes patients who underwent PEHR to identify the factors associated with postoperative symptom improvement and radiographic recurrence. We furthermore use propensity score matching to compare patients undergoing initial and reoperative PEHR to identify the factors predictive of recurrence or need for reoperation.
METHODS: After IRB approval, patients who underwent PEHR at a tertiary care center between January 2018 and December 2022 were identified. Patient characteristics, preoperative imaging, operative findings, and postoperative outcomes were recorded. A computational generalization of inverse propensity score weight was then used to construct populations of initial and redo PEHR patients with similar covariate distributions.
RESULTS: A total of 244 patients underwent PEHR (78.7% female, mean age 65.4 ± 12.3 years). Most repairs were performed with crural closure (81.4%) and fundoplication (71.7%) with 14.2% utilizing mesh. Postoperatively, 76.5% of patients had subjective symptom improvement and of 157 patients with postoperative imaging, 52.9% had evidence of radiographic recurrence at a mean follow-up of 10.4 ± 13.6 months. Only 4.9% of patients required a redo operation. Hernia type, crural closure, fundoplication, and mesh usage were not predictors of radiographic recurrence or symptom improvement (P > 0.05). Propensity weight score analysis of 50 redo PEHRs compared to a matched cohort of 194 initial operations revealed lower rates of postoperative symptom improvement (P < 0.05) but no differences in need for revision, complication rates, ED visits, or readmissions.
CONCLUSIONS: Most PEHR patients have symptomatic improvement with minimal complications and reoperations despite frequent radiographic recurrence. Hernia type, crural closure, fundoplication, and mesh usage were not significantly associated with recurrence or symptom improvement. Compared to initial PEHR, reoperative PEHRs had lower rates of symptom improvement but similar rates of recurrence, complications, and need for reoperation.

A Bochdalek hernia is a rare congenital diaphragmatic hernia often diagnosed in infancy and classically occurring on the left side. We report a case of a 78-year-old female who presented with a right-sided posterolateral diaphragmatic hernia containing multiple loops of bowel with evidence of ischemia as well as a type 4 paraesophageal hernia. The stomach was rotated on the organoaxial plane, and the duodenum was within the mediastinum. The patient was taken emergently for an exploratory laparotomy. A posterolateral hernia defect containing 50 cm of strangulated small bowel was identified and resected, a primary stapled enteroenterostomy was performed and the hernia defect was repaired primarily. The stomach was reduced, a primary crura repair was performed, and gastropexy was performed with a gastrojejunostomy tube. The patient was transferred to the intensive care unit, and subsequently extubated, enteral feeds were initiated, and had anticipated discharge to a skilled nursing facility. This case highlights an uncommon atraumatic presentation of an adult with a congenital diaphragmatic hernia. Its rarity is further denoted due to its right-sided laterality and strangulated small bowel as the usual herniated abdominal organs are the liver or colon.

BACKGROUND: Hiatal Hernia (HH) is a common structural defect of the diaphragm. Laparoscopic repair with suturing of the hiatal pillars followed by fundoplication has become standard practice. In an attempt to lower HH recurrence rates, mesh reinforcement, commonly located at the posterior site of the esophageal hiatus, has been used. However, effectiveness of posterior mesh augmentation is still up to debate. There is a lack of understanding of the mechanism of recurrence requiring further investigation. We investigated the anatomic location of HH recurrences in an attempt to assess why HH recurrence rates remain high despite various attempts with mesh reinforcement.
METHODS: A retrospective case series of prospectively collected data from patients with hiatal hernia repair between 2012 and 2020 was performed. In total, 54 patients with a recurrent hiatal hernia operation were included in the study. Video clips from the revision procedure were analyzed by a surgical registrar and senior surgeon to assess the anatomic location of recurrent HH. For the assessment, the esophageal hiatus was divided into four equal quadrants. Additionally, patient demographics, hiatal hernia characteristics, and operation details were collected and analyzed.
RESULTS: 54 patients were included. The median time between primary repair and revision procedure was 25 months (IQR 13-95, range 0-250). The left-anterior quadrant was involved in 43 patients (80%), the right-anterior quadrant in 21 patients (39%), the left-posterior quadrant in 21 patients (39%), and the right-posterior quadrant in 10 patients (19%).
CONCLUSIONS: In this study, hiatal hernia recurrences occured most commonly at the left-anterior quadrant of the hiatus, however, posterior recurrences were not uncommon. Based on our results, we hypothesize that both posterior and anterior hiatal reinforcement might be a suitable solution to lower the recurrence rate of hiatal hernia. A randomized controlled trial using a circular, bio-absorbable mesh has been initiated to test our hypothesis.

Hiatal hernias are commonly encountered in clinical practice. In certain cases, especially in large hiatal hernias, gastric volvulus can occur. Patients with volvulus typically will present with vomiting, chest pain, shortness of breath, and dysphagia. In extreme cases, gastric volvulus can result in gastric necrosis requiring partial or total gastrectomy. Here we highlight a case of a 76-year-old female with a known large type IV hiatal hernia who was found to have gastric volvulus with necrosis requiring partial sleeve gastrectomy. This case demonstrates the rare, but possible complication of gastric necrosis secondary to gastric volvulus from a large hiatal hernia, prompting emergent surgical intervention.

Hiatal hernia is a frequent pathology in the population; however, the most frequent hiatal hernia is type I, which accounts for up to 95% incidence, types II, III, and IV being less frequent and representing between 5% and 15%, and even less common are giant hernias. The definition of the giant hernia is still not exact in the literature; some authors define giant or massive hiatal hernia as one in which the hernia occupies more than 30% of the stomach and/or passes from other abdominal structures to the thorax. We describe the case of a patient with gastrointestinal symptomology without response to a proton pump inhibitor, with base exacerbation that required imaging studies, showing a large hernia defect passing to the thorax from abdominal organs (stomach, spleen, mesenteric fat), as well as alteration of the gastric and spleen axis with ascent in pancreatic body and tail, which corresponds to a giant hiatal hernia. Said pathology is very infrequent, with recurrences and postoperative complications. Our patient recovered from the surgical procedure with therapeutic success.
