RESUMEN

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.

RESUMEN

Acute pericarditis is a serious and potentially fatal disease in which a diagnostic workup is not always straightforward. Hiatal hernia, on the other hand, is often asymptomatic and can be easily diagnosed if symptomatic. In advanced forms of hiatal hernia, oppression of intrathoracic organs and heart failure can occur. In uncommon cases, the large intestine can also be translocated into the chest cavity, and very rarely, it can be perforated with the development of mediastinitis and/or pericarditis. We report the case of a 74-year-old female with a 1.5-month history of chest pain with elevated inflammatory markers. This patient was empirically treated with antibiotics for suspected pneumonia. After a few weeks, due to a worsening of the patient's condition, an echocardiogram and then a CT of the chest were performed, showing a large hiatal hernia and a very probable purulent pericarditis, necessitating a surgical exploration. A cardiac surgeon found stercoral contents in the pericardium, with a fistula at the apex of the heart. The operation continued with an exploration of the abdominal cavity; the general surgeon returned the massive hiatal hernia to the abdomen, the contents of which were the stomach and transverse colon. An extensive perforation in the transverse colon was found. Lavage, drainage, and resection of the affected part of the intestine were performed, and a permanent (terminal) colostomy was constructed. The patient was in severe septic shock with multiorgan failure and died 10 hours after surgery despite maximal therapy. This case highlights the importance of interdisciplinary cooperation and the importance of considering the possible fistula in the co-occurrence of hiatal hernia and pericarditis.

RESUMEN

PURPOSE: Our group has proposed that aspiration of gastric contents leads to exposure of normally sequestered lung self-antigens (SAgs), specifically collagen-V (Col-V) and K-α-1-tubulin (Kα1T), which elicits an immune response characterized by increasing concentrations of self-antibodies (SAbs) anti-Col-V and anti-Kα1T. We sought to establish the point prevalence of abnormally elevated concentrations of SAbs among patients with pathological gastroesophageal reflux disease (GERD) and/or hiatal hernia undergoing antireflux surgery (ARS). METHODS: For this cross-sectional study, we retrieved a plasma aliquot from the Norton Thoracic Institute BioBank from blood samples that were taken preoperatively from patients who underwent ARS between November 2019 and August 2022. Enzyme-linked immunosorbent assays were employed to detect and quantify anti-Col-V and anti-Kα1T. RESULTS: Samples from 43 patients (females, n = 34 [79.1%]; mean age, 62 ± 12 years; and mean BMI, 30.5 ± 7  kg/m2) were analyzed. Before ARS, 28 (65.1%, CI95: 50.3-80.0%) patients had abnormally elevated concentrations of anti-Col-V and 19 (44.2%, CI95: 28.7-59.7%) had elevated concentrations of circulating anti-Kα1T. Overall, 13 patients (30.2%) had low (i.e., normal) concentrations of both SAbs, 13 (30.2%) were positive only for one, and 17 (39.5%) were positive for both SAbs. CONCLUSION: A relative high point prevalence of abnormally elevated circulating SAbs (i.e., anti-Col-V and/or anti-Kα1T) before ARS was found. This result suggests clinically unsuspected pulmonary parenchymal injury secondary to GERD-related aspiration. Further studies are required to confirm this hypothesis and to identify alternative non-invasive early biomarkers of GERD-related lung damage.

RESUMEN

BACKGROUND: The surgical technique in large hiatal hernia (HH) repair is controversially discussed and the outcome measures and follow-up schemes are highly heterogeneous. The aim of this study is to assess the true recurrence rate using computed tomography (CT) in patients with standardized large HH repair. METHODS: Prospective single-center study investigating the outcome after dorsal, mesh-enforced large HH repair with anterior fundoplication. Endoscopy was performed after 3 months and clinical follow-up and CT after 12 months. RESULTS: Between 2012 and 2021, 100 consecutive patients with large HH were operated in the same technique. There were two reoperations within the first 90 days for cephalad migration of the fundoplication. Endoscopic follow-up showed a correct position of the fundoplication and no relevant other pathologies in 99% of patients. Follow-up CT was performed in 100% of patients and revealed 6% of patients with a cephalad slippage, defined as migration of less than 3 cm of the wrap, and 7% of patients with a recurrent hernia. One patient of each group underwent subsequent reoperation due to symptoms. There was no statistical correlation between abnormal radiological findings and clinical outcomes with 69.2% of patients being asymptomatic. Multivariate logistic regression did not show any prognostic factor for an unfavorable radiologic outcome. Ninety-four percent of patients rated their outcomes as excellent or good. CONCLUSION: Radiological follow-up after large HH repair using CT allows to detect slippage of the fundoplication wrap and small recurrences. Patients with unfavorable radiological outcomes rarely require operative revision but should be considered for further follow-up.

RESUMEN

A short esophagus is generally diagnosed during antireflux surgery and is defined as a distance of less than 2 cm between the gastroesophageal junction and the apex of the hiatus. We present a female patient with a CT diagnosis of type IV hiatal hernia who was scheduled for antireflux surgery, showed a short esophagus during the procedure, opted to perform Collis gastroplasty, and discharged without complications. A short esophagus remains a controversial topic. Some authors argue that it is more common than suspected and responsible for high recurrences in specific patient groups.

RESUMEN

Serpentine-like syndrome, characterized by the combination of intrathoracic stomach, a notably short esophagus anomaly, splenic abnormalities, and cervical spine malformations, has been associated with a high mortality rate since its identification in 2008. This report presents the case of a remarkable patient who recently celebrated her fifth birthday, marking her as the oldest documented individual with this syndrome to date. Highlighting the significance of comprehensive evaluations for concurrent malformations, the report discusses potential treatment modalities and challenges inherent in managing patients with this intricate syndrome. A comprehensive review of previously published cases is provided, comparing surgical interventions, causes of death, and age at the time of demise. This report underscores the importance of ongoing research and collaborative efforts to optimize outcomes for individuals afflicted with serpentine-like syndrome.

RESUMEN

Background: The relationship between laparoscopic sleeve gastrectomy (LSG) and gastroesophageal reflux disease (GERD) is intricate. Hiatal hernia repair or gastropexy can have an impact on postoperative GERD. Aim: To assess the effect of the repair of an accidentally discovered HH and/or gastropexy on the development of de novo postoperative GERD symptoms after LSG. Methods: This retrospective study included all obese patients who underwent LSG at our hospital from January 2018 to June 2022. The data retrieved from patients' files comprised demographic and clinical data, including BMI, GERD symptoms, and comorbidities. Hiatal hernias, surgical technique, gastropexy, duration, and intraoperative complications were recorded. Postoperative data included early and late postoperative complications, weight loss, de novo GERD, and medication use. Results: The study included 253 patients, 89 males (35.2%) and 164 females (64.8%), with a mean age of 33.3±10.04 years. De novo GERD was detected in 94 individuals (37.15%). HH was accidentally found and repaired in 29 patients (11.5%). Only 10.3% of LSG and HH repair patients had de novo GERD symptoms, compared to 40.6% of non-HH patients. 149 patients (58.9%) had gastropexy with LSG. Postoperative de novo GERD symptoms were comparable for LSG with gastropexy (40.5%) and LSG alone (40.9%). Conclusion: After one year, concurrent hiatal hernia repair and LSG seem to be safe and beneficial in lowering postoperative de novo GERD symptoms. The inclusion of gastropexy with LSG had no significant impact on postoperative de novo GERD. Both HH repair and gastropexy lengthened the operation but did not increase its complications.

RESUMEN

We present the case of an 82-year-old female with obstructive jaundice secondary to a malignant distal biliary stricture. Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) was performed. The presence of a giant hiatal hernia induced dynamic liver movement during respiration, leading to unstable scope positioning. Despite the successful placement of a long, partially covered metal stent from the left intrahepatic bile duct to the intra-abdominal stomach, computed tomography performed three days later revealed free air and an increased distance between the liver and stomach. A subsequent endoscopy confirmed impending stent migration into the abdominal cavity, necessitating the insertion of an additional metal stent through the existing stent's mesh. The presence of a giant hiatal hernia may be considered a relative contraindication for EUS-HGS due to dynamic movements of the stomach and liver during respiration, which can cause stent migration, increased air leakage, and difficulty in establishing a stable fistula between these organs.

RESUMEN

Background: Hiatal hernia (HH) is a common finding in gastroscopy. The aim of the present study was to investigate the frequency rate of HH among patients who underwent esophagogastroduodenoscopy (EGD) according to their age, gender, and procedural indication. Methods: A multicenter, retrospective study including all EGDs was conducted across seven endoscopy departments between 2016 and 2021. Demographic information, procedural indications, and findings from the initial EGD were collected. Results: Of the 162,608 EGDs examined, 96,369 (59.3%) involved female patients. HH was identified in 39,619 (24.4%) of all EGDs performed, comprising small HH in 31,562 (79.6%) and large HH in 3,547 (9.0%). The frequency of HH was 16.5% in the age group of ≤50 years and 37.3% in those aged ≥81 years. HH was diagnosed in 38.7% (11,370) of patients with heartburn/reflux symptoms, 31.5% of those with dysphagia, 28.5% of those with positive fecal occult blood tests, and 24.3% of those who would undergo bariatric surgery. Age (odds ratio 1.030), female gender (odds ratio 1.309), reflux symptoms (odds ratio 2.314), and dysphagia (odds ratio 1.470) were identified as predictors for HH. Conclusions: Risk factors for HH diagnosed by EGD in symptomatic patients were shown to be advanced age, female gender, and the presence of heartburn or dysphagia.

RESUMEN

OBJECTIVE: Data on graded complications and their frequency after laparoscopic revisional antireflux and hiatal hernia surgery compared to primary surgery are lacking. We describe 30- and 90-day morbidity using the Clavien-Dindo (CD) classification. METHODS: 298 patients underwent revision surgery between 2003-2020 and were propensity matched to primary surgeries [1:2 ratio] based on age, sex, BMI, ASA classification, LA grade esophagitis, presence of Barrett's, and indication for surgery. Complications were graded using the CD classification, with the highest grade of complication reported per patient. RESULTS: After matching, both groups were majority females, with a median age of 60 and a median BMI of 29.5. Most were healthy, with non-erosive esophagitis and modest levels of Barrett's esophagus. A laparoscopic Nissen fundoplication was most common; however, a partial fundoplication was more common in revisions. Mesh, relaxing incisions and Collis were more common in revisional surgery. At 30-days, total complications were similar [23.5%, (70/298) versus 20.6% (123/596), p=0.373] with 1 death in each group. Minor complications (0.001) more frequently, with esophageal obstruction requiring revision and esophageal/gastric leak being most common. Grade CD4A/B complications were comparable in both groups. At 90-days, revision patients experienced overall complications [7.1% (21) vs 2.0% (12), p=0.003], and CD3B complications [1.0% (3) vs 0 , p=0.037] more frequently, with intra-abdominal abscess washout being the most common CD3B complication. CONCLUSION: Revisional surgery results in similar total complications at 30 days but additional complications can occur out to 90 days.

RESUMEN

Gastric volvulus, characterized by stomach rotation, is a rare condition arising from congenital or acquired factors. Predominantly affecting pediatric and elderly populations, it necessitates a high index of suspicion for timely diagnosis. Delayed recognition may precipitate severe complications such as ischemia, strangulation, and septic shock, often culminating in fatal outcomes. We present a case of a 71-year-old male initially admitted for suspected gastroenteritis, subsequently developing acute gastric volvulus during hospitalization, necessitating immediate surgical intervention. This case contributes to the scant literature on gastric volvulus in the elderly demographic.

RESUMEN

The rapid uptake of minimally invasive antireflux surgery has led to interest in learning curves for this procedure. This study ascertains the learning curve in laparoscopic and robotic-assisted antireflux surgery. A systematic review of the literature pertaining to learning curves in minimally invasive fundoplication with or without hiatal hernia repair was performed using PubMed, Medline, Embase, Web of Science, and Cochrane Library databases. A meta-regression analysis was undertaken to identify the number of cases to achieve surgical proficiency, and a meta-analysis was performed to compare outcomes between cases that were undertaken during a surgeon's learning phase and experienced phase. Twenty-five studies met the eligibility criteria. A meta-regression analysis was performed to quantitatively investigate the trend of number of cases required to achieve surgical proficiency from 1996 to present day. Using a mixed-effects negative binomial regression model, the predicted learning curve for laparoscopic and robotic-assisted antireflux surgery was found to be 24.7 and 31.1 cases, respectively. The meta-analysis determined that surgeons in their learning phase may experience a moderately increased rate of conversion to open procedure (odds ratio [OR] 2.44, 95% confidence interval [CI] 1.28, 4.64), as well as a slightly increased rate of intraoperative complications (OR 1.60; 95% CI 1.08, 2.38), postoperative complications (OR 1.98; 95% CI 1.36, 2.87), and needing reintervention (OR 1.64; 95% CI 1.16, 2.34). This study provides an insight into the expected caseload to be competent in performing antireflux surgery. The discrepancy between outcomes during and after the learning curve for antireflux surgery suggests a need for close proctorship for learning surgeons.

RESUMEN

OBJECTIVE: To study the safety and efficacy of laparoscopic fundoplication and hiatal hernia repair for gastroesophageal reflux disease following hiatal hernia. MATERIAL AND METHODS: We retrospectively analyzed 56 patients with gastroesophageal reflux disease and hiatal hernia .They underwent laparoscopic fundoplication and hiatal hernia repair between January 2020 and January 2023. RESULTS: All surgeries were successful without conversion to open surgery. Surgery time was 56-180 min (mean 68.4±3.6), blood loss 30-200 ml (mean 40.3±5.6). No mortality and severe complications occurred. All patients were followed-up for 6-24 months. The GERD-Q and De Meester scores were significantly lower after 6 months compared to baseline values (p <0.05), and resting pressure was lower. Tone of lower esophageal sphincter was significantly higher compared to preoperative level (p <0.05). In 1-2 years after surgery, symptoms completely disappeared in 48 patients and significantly improved in 6 patients. Two patients had no improvement. Contrast-enhanced examination found no recurrent hiatal hernia and digestive tract obstruction. CONCLUSION. L: Aparoscopic fundoplication and hiatal hernia repair is safe and effective for gastroesophageal reflux disease with hiatal hernia.

RESUMEN

Postoperative hiatal hernia is a rare and specific complication after esophagectomy. This complication leads to emergency and affects mortality. Incidence of this complication has increased due to the great number of minimally invasive procedures over the past decades. In addition, chronic cough, preoperative hiatal hernia and transhiatal approach also increase the risk of recurrent hernias. Most post-esophagectomy hiatal hernias do not require emergency surgery. About 70% of patients have symptoms reducing the quality of life. About 25% of cases are asymptomatic and discovered incidentally during follow-up examinations. The role of surgery for asymptomatic post-esophagectomy hernias is a matter of debate because the risk of symptoms or complications is poorly predictable. Surgical treatment is the only radical method for symptomatic or complicated hernias. However, there is still no consensus regarding surgical approach and technique. Most surgeons prefer open surgery fearing severe adhesive process and other technical difficulties. Laparoscopic approach is widely accepted as the "gold standard" for primary hiatal hernia. However, minimally invasive access for post-esophagectomy hiatal hernias is not sufficiently studied and described in several case reports. Currently, it is very important to study the risk factors of hiatal hernias after esophagectomy. We present successful laparoscopic repair of hiatal hernia after hybrid McKeown esophagectomy.

RESUMEN

BACKGROUND: Hiatal and paraesophageal hernia (HH/PEH) recurrence is the most common cause of failure after gastroesophageal anti-reflux surgery. Crural reinforcement with mesh has been suggested to address this issue, but its efficacy remains debated. In this study, we aimed to determine the impact of biosynthetic mesh reinforcement compared to suture cruroplasty on anatomic and symptomatic hernia recurrence. METHOD: Data of patients who underwent robotic HH/PEH repair with suture cruroplasty with or without biosynthetic mesh reinforcement between January 2012 and April 2024 were retrospectively reviewed. Gastroesophageal reflux disease symptoms and anatomic hernia recurrence were assessed at short-term (3 months to 1 year) and longer-term (≥ 1 year) follow-up. Symptomatic hernia recurrence was defined as having both anatomic recurrence and symptoms. RESULTS: Out of the 503 patients in the study, 308 had undergone biosynthetic mesh repair, while 195 had suture-only repair. After the surgery, both groups demonstrated comparable improvements in symptoms. Short-term anatomic hernia recurrence rates were 11.8% and 15.6% for mesh and suture groups, respectively (p = 0.609), while longer-term rates were 24.7% and 44.9% (p = 0.015). The rates of symptomatic hernia recurrence in the same group were 8.8% and 14.6% in the short-term (p = 0.256), and 17.2% and 42.2% in longer-term follow-ups (p = 0.003). In the repair of medium and large-size hernias, mesh reinforcement resulted in a 50.0% relative risk reduction in anatomic hernia recurrences and a 59.2% reduction in symptomatic hernia recurrences at ≥ 1-year follow-up. CONCLUSION: After more than a year of follow-up, it has been found that using biosynthetic mesh for medium and large hiatal or paraesophageal hernia repair significantly reduces the likelihood of both anatomic and symptomatic recurrence compared to using only suture cruroplasty. These findings strongly support the use of biosynthetic mesh to manage larger hernias. However, further long-term multicenter randomized studies are needed to provide more conclusive evidence.

RESUMEN

BACKGROUND: Transoral incisionless fundoplication (TIF) is safe and effective in select patients with hiatal hernias ≤ 2 cm with refractory gastroesophageal reflux disease (GERD). For patients with hiatal hernias > 2 cm, concomitant hiatal hernia (HH) repair with TIF (cTIF) is offered as an alternative to conventional anti-reflux surgery (ARS). Yet, data on this approach is limited. Through a comprehensive systematic review, we aim to evaluate the efficacy and safety of cTIF for managing refractory GERD in patients with hernias > 2 cm. STUDY DESIGN: We conducted a systematic review of studies evaluating cTIF outcomes from PubMed, EMBASE, SCOPUS, and Cochrane databases up to February 14, 2024. Primary outcomes included complete cessation of proton pump inhibitors (PPIs). Secondary outcomes included objective GERD assessment, adverse events, and treatment-related side effects. Pooled analysis was employed wherever feasible. RESULTS: Seven observational studies (306 patients) met the inclusion criteria. Five were retrospective cohort studies and two were prospective observational studies. The median rate of discontinuation of PPIs was 73.8% (range 56.4-94.4%). Significant improvements were observed in disease-specific, validated GERD questionnaires. The median rate for complications was 4.4% (range 0-7.9%), and the 30-day readmission rate had a median of 3.3% (range 0-5.3%). The incidence of dysphagia was 11 out of 164 patients, with a median of 5.3% (range 0-8.3%), while the incidence of gas bloating was 15 out of 127 patients, with a median of 6.9% (range 0-13.8%). CONCLUSION: Current data on cTIF suggests a promising alternative to ARS with comparable short-term efficacy and safety profile for managing refractory GERD with a low side effect profile. However, longer-term data and comparative efficacy studies are needed.

RESUMEN

BACKGROUND: Hiatal hernia repair (HHR) performed concurrently with vertical sleeve gastrectomy (VSG) has been shown to improve postoperative gastroesophageal reflux disease (GERD). However, data on the optimal extent of esophageal mobilization during repair are lacking. Mobilization techniques for HHR during VSG include partial (PM) or full (FM) mobilization of the esophagus. We hypothesize that patients who undergo full mobilization will be less likely to develop postoperative reflux. METHODS: A single-institution retrospective review of all patients who underwent a VSG with a HHR between 2014 and 2021 was conducted. The primary outcome was postoperative reflux symptoms defined by diagnosis in the medical record, utilization of anti-reflux medications, and GERD health-related quality of life (GERD-HRQL) scores obtained via patient surveys. RESULTS: There were 190 patients included with 80 patients (42.1%) undergoing PM and 110 (57.9%) undergoing FM. Rates of preoperative reflux were similar between the two groups (47.5% vs. 51.8%; p = 0.55). During the GERD-HRQL survey, there were 114 patients (60.0%) contacted with a participation rate of 91.2% (104 patients). Patients with preoperative reflux who underwent PM were found to have a higher rate of reported postoperative reflux (90.0% vs. 62.5%; p = 0.03) and higher GERD-HRQL scores (16.40 ± 9.95 vs. 10.84 ± 9.01; p = 0.04). Patients without preoperative reflux did not have a significant difference in reported reflux (55.0% vs. 51.7%; p = 0.82) or GERD-HRQL scores (12.35 ± 14.14 vs. 9.93 ± 9.46; p = 0.25). CONCLUSION: Our study found that postoperative GERD was higher in patients with preexisting reflux who underwent partial esophageal mobilization during concurrent hiatal hernia repair with vertical sleeve gastrectomy. In patients without preoperative GERD, our data suggest that postoperative reflux symptoms are not dependent on the extent of esophageal mobilization during hiatal hernia repair with vertical sleeve gastrectomy.

RESUMEN

Mesh-augmented hernia repair is the gold standard in abdominal wall and hiatal/diaphragmatic hernia management and ranks among the most common procedures performed by general surgeons. However, it is associated with a series of drawbacks, including recurrence, mesh infection, and adhesion formation. To address these weaknesses, numerous biomaterials have been investigated for mesh coating. Platelet-rich plasma (PRP) is an autologous agent that promotes tissue healing through numerous cytokines and growth factors. In addition, many reports highlight its contribution to better integration of different types of coated meshes, compared to conventional uncoated meshes. The use of PRP-coated meshes for hernia repair has been reported in the literature, but a review of technical aspects and outcomes is missing. The aim of this comprehensive review is to report the experimental studies investigating the synergistic use of PRP and mesh implants in hernia animal models. A comprehensive literature search was conducted across PubMed/Medline, Web of Science, and Scopus without chronological constraints. In total, fourteen experimental and three clinical studies have been included. Among experimental trials, synthetic, biologic, and composite meshes were used in four, nine, and one study, respectively. In synthetic meshes, PRP-coating leads to increased antioxidant levels and collaged deposition, reduced oxidative stress, and improved inflammatory response, while studies on biological meshes revealed increased neovascularization and tissue integration, reduced inflammation, adhesion severity, and mechanical failure rates. Finally, PRP-coating of composite meshes results in reduced adhesions and improved mechanical strength. Despite the abundance of preclinical data, there is a scarcity of clinical studies, mainly due to the absence of an established protocol regarding PRP preparation and application. To this point in time, PRP has been used as a coating agent for the repair of abdominal and diaphragmatic hernias, as well as for mesh fixation. Clinical application of conclusions drawn from experimental studies may lead to improved results in hernia repair.
