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

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

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

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

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 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

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

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

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.

RESUMEN

We present a female in her sixties with a recurrent paraesophageal hernia status post open Nissen fundoplication and multiple esophageal dilations who underwent a robotic paraesophageal hernia repair, with extensive lysis of adhesions. The stomach and esophagus were dissected off the crura and the previous wrap was undone. Once the entirety of the stomach and esophagus were freed from their surrounding structures, the hernia sac was able to be excised. The crural defect was closed and gastropexy was performed. The patient had an uneventful postoperative course and was discharged home. This case is presented to provide evidence that robotic repair presents a viable option in the reoperation of patients following an open Nissen fundoplication as well as provide an overview of the types of hiatal hernias and the indications and options for surgical intervention.

RESUMEN

BACKGROUND: Studies comparing outcomes between robotic and laparoscopic paraesophageal hernia repairs have yielded conflicting results. We sought to analyze early postoperative complications between these approaches using a newly available NSQIP variable indicating robot use. METHODS: We queried the 2022 ACS NSQIP database for adult patients undergoing elective minimally invasive hiatal hernia repair. Chi-squared and Kruskal-Wallis tests were used to compare cohort characteristics. Logistic, linear, and Cox proportional hazards regression analyses were used to compare perioperative outcomes between the laparoscopic and robotic groups. RESULTS: We identified 4345 patients who underwent repair using a laparoscopic (2778 patients; 63.9%) or robotic (1567 patients; 36.1%) approach. Most (73.1%) were female, and the median age was 65 (IQR 55, 73). Patients who underwent robotic repair were younger (median age 64 vs 66), had a slightly higher body mass index (BMI; median 30.2 vs 29.9), and were more likely to have hypertension (53.0% vs 48.5%), all p < 0.01. On unadjusted analysis the robotic approach was associated with decreased 30-day mortality (0.0% vs 0.4%, p < 0.01). After adjusting for age, gender, race, BMI, and hypertension, the robotic approach was not associated with increased major complications (5.6% vs 5.1%, AOR 1.13, 95% CI 0.86, 1.49), minor complications (0.9% vs 1.5%, AOR 1.20, 95% CI 0.74, 1.93), or unplanned readmission (6.5% vs 5.5%, AHR 1.17, 95% CI 0.89, 1.54), all p ≥ 0.26. After adjusting for age and hypertension, the robotic cohort had an increased risk of myocardial infarction (AOR 2.53, 95% CI 1.01, 6.33, p = 0.048) and pulmonary embolism (AOR 2.76, 95% CI 1.17, 6.49, p = 0.02), although none resulted in 30-day mortality. CONCLUSIONS: Robotic and laparoscopic paraesophageal hernia repairs had similar overall complication and readmission rates. The robotic cohort had an increased risk of myocardial infarction and pulmonary embolism but no 30-day mortality. Current data support the use of both robotic and laparoscopic approaches for paraesophageal hernia repair.

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

Emergency surgery for a hiatal hernia (HH) is uncommon. However, mediastinal gastric perforation may occasionally present as the initial symptom of HH and demonstrate high mortality rates. Managing mediastinal gastric perforation in HH has no established standard surgical technique, and the selection of surgical techniques may be challenging. A 78-year-old female patient was referred to our department because of an upper gastrointestinal perforation in HH based on computed tomography (CT) results. Determining the possibility of esophageal perforation and intrathoracic penetration was difficult according to CT results alone, and whether a transthoracic or transabdominal approach was preferable. We diagnosed the patient with a mediastinal gastric perforation in HH without intrathoracic penetration based on an additional gastrointestinal contrast study and a right thoracentesis. We treated the patient with laparotomy, involving the perforation site and esophageal hiatus closure and gastropexy. Postoperatively, the patient experienced complications associated with delayed gastric emptying and aspiration pneumonia. Fortunately, no severe infections, such as residual abscess formation or empyema, were observed, and the recovery progressed favorably. Mediastinal gastric perforation should be considered a differential diagnosis for elderly patients with sudden-onset chest pain and dyspnea, and the threshold for imaging should be lowered. Identifying the perforation site and the presence of intrathoracic penetration based on preoperative results is useful for determining the appropriate surgical technique. Postoperative quality of life to the extent feasible needs to be considered, as the selection of surgical technique may cause subsequent recurrence or reflux symptoms.

RESUMEN

A hiatal hernia occurs when the contents of the abdominal cavity, most often the stomach, protrude into the chest cavity through the esophageal hiatus. The hiatus is an elliptical-shaped outlet, typically formed by parts of the right diaphragmatic crus surrounding the distal esophagus. This ailment can transpire due to either the broadening of the specific diaphragmatic opening or a shortening in the overall length of the esophagus, leading to herniation of the stomach into the thoracic region. Raised pressure in the abdominal region may also be one of the culprits. Patients with a hiatal hernia usually remain asymptomatic, but patients might have difficulty swallowing both liquids and solids in the advanced stages of the disease. The disease is rarely accompanied by reflux of gastric acid into the esophagus due to decreased activity of the lower esophageal sphincter, leading to increased complaints of epigastric pain and ulceration near the gastroesophageal junction. Long-standing cases can increase the risk of developing Barrett's esophagus with dysplasia, which may advance to esophageal carcinoma in later stages. Advanced age and obesity are significant risk factors for hiatal hernia. Obese individuals, in particular, experience higher intra-abdominal pressure, which significantly raises the likelihood of developing a hiatal hernia. The hernia may be diagnosed through an upper gastrointestinal endoscopy or radiologically through a chest X-ray in the posterior-anterior view, defining the border of the esophagus. Hence, this facilitates a more seamless and precise diagnosis. Surgical fundoplication treatment improves the patient's condition better than solitary medical management. Overall, addressing the condition surgically often yields more favorable outcomes and enhances the patient's quality of life. Hiatal hernia usually presents with no or minimal clinical manifestations. Thus, this case report highlights the importance of comprehensive clinical management of such cases.

RESUMEN

PURPOSE: The purpose of this narrative review is to evaluate the implementation of robotic surgery in hiatal hernia and crural repair, based on the existing literature and to compare this approach to other established techniques. METHODS: We performed a non- systematic literature search of PubMed and MEDLINE on February 25, 2024 for papers published to date focusing on the surgical repair of hiatal hernias using the robotic platform. After eliminating publications based on eligibility criteria, 13 studies were selected for analysis. RESULTS: Robotic surgery is increasingly utilized in hiatal hernia repair due to its enhanced ergonomics and superior visualization capabilities. Operative times vary, with some studies indicating longer durations for robotic surgery (e.g., Giovannetti et al. demonstrated median operative time of 196 min for robotic compared to 145 min for laparoscopic) while others report shorter times (e.g., Lang F et al. demonstrated 88 min for robotic versus 102 min for laparoscopic). Recurrence rates between robotic and laparoscopic repairs are comparable, with reported recurrence rates of 1.8% for robotic and 1.2% for laparoscopic approaches by Benedix et al. Robotic surgery offers potential advantages, including reduced intraoperative blood loss (e.g., Giovannetti et al. mentioned median blood loss of 20 ml for robotic versus 50 ml for laparoscopic). The length of hospital stay and postoperative complication rates also vary, with some studies suggesting shorter stays and fewer complications for robotic surgery as surgeons become more proficient. Soliman et al. reported a statistically significant reduction in complication rates with robotic surgery (6.3% versus 19.2%). CONCLUSIONS: Robotic surgery presents promising results regarding the length of hospital stay, conversion rate to open surgery and postoperative complication rates when compared to laparoscopy based on the existing literature. Despite the lack of striking differences, robotic hiatal hernia repair is a valid and evolving approach.
