Contemporary association of preoperative malnutrition and outcomes of hiatal hernia repairs in the United States

BackgroundHypoalbuminemia has been used as a surrogate for malnutrition and is associated with worse postoperative outcomes across major operations. Because patients with hiatal hernia often have inadequate caloric intake, we examined the association of serum albumin levels with outcomes after hiatal hernia repair. MethodsAdults undergoing elective and non-elective hiatal hernia repair via any approach were tabulated from the 2012 to 2019 National Surgical Quality Improvement Program. Patients were stratified into the Hypoalbuminemia cohort if serum albumin <3.5 mg/dL using restricted cubic spline analysis. Major adverse events were defined as a composite of all-cause mortality and major complications per the American College of Surgeons National Surgical Quality Improvement Program risk calculator. Entropy balancing was used to adjust for intergroup differences. Multivariable regression models were then constructed to assess the association of preoperative albumin with major adverse events, postoperative length of stay, and 30-day readmission. ResultsOf 23,103 patients, 11.7% comprised the Hypoalbuminemia cohort. The Hypoalbuminemia group was older, less commonly of White race, and less likely to have an independent functional status than others. They were also more likely to undergo inpatient, non-elective surgery via laparotomy. After entropy balancing and adjustment, hypoalbuminemia remained associated with increased odds of major adverse events and multiple complications and longer adjusted postoperative length of stay. There was no significant difference in adjusted odds of readmission. ConclusionWe used a quantitative methodology to establish a serum albumin threshold of 3.5 mg/dL associated with increased adjusted odds of major adverse events, increased postoperative length of stay, and postoperative complications after hiatal hernia repair. These results may guide preoperative nutrition supplementation.

Anterior reconstruction of the esophageal hiatus: a novel approach for the repair of large diaphragmatic hernias

Introduction: Paraesophageal hernias (PEH) often require surgical repair. The standard approach, primary posterior hiatal repair, has been associated with a high recurrence rate. Over the past few years, we have developed a new approach for repairing these hernias, which we believe restores the original anatomy and physiology of the esophageal hiatus. Our technique includes anterior crural reconstruction with routine anterior mesh reinforcement and fundoplication. Objective: To determine the safety and the clinical success of anterior crural reconstruction with routine mesh reinforcement. Material and methods: Data were collected retrospectively on 178 consecutive patients who had a laparoscopic repair of a symptomatic primary or recurrent PEH between 2011 and 2021 using the above technique. The primary outcome was clinical success, and the secondary outcome was 30 days of major complications and patient satisfaction. This was assessed by imaging tests, gastroscopies, and clinical follow-up. Results: Mean follow-up was 65 (SD 37.1) months. No intraoperative or 30 days postoperative mortality or major complications were recorded. Recurrence rate requiring a re-operation was 8.4% (15/178). Radiological and gastroenterological evidence of minor type 1 recurrence was 8.9%. Conclusion: This novel technique is safe with satisfactory long-term results. The outcome of our study will hopefully motivate future randomized control trials.

O157 Outcomes of concurrent hiatus hernia repair with different bariatric surgery procedures: a systematic review

Abstract Introduction Hiatus hernia (HH) are prevalent among patients with obesity. HH repair is often performed concurrently during bariatric surgery (BS), but a consensus on the safety and effectiveness of concurrent HH repair (HHR) and BS remains unclear. We, therefore, undertook a systematic review of the safety and effectiveness of concurrent HHR and BS through the measurement of multiple postoperative outcomes. Methods A comprehensive search discovered 17 studies relating to concurrent BS and HHR. BS procedures included laparoscopic Sleeve Gastrectomy (LSG), Roux-en-Y Gastric Bypass (LRYGB), and Adjustable Gastric Banding (LAGB). Extracted from these studies were pre- and post-operatives and measurements and outcomes. Results For LSG, 8 of 11 studies concluded concurrent procedures to be safe and effective with no increase in mortality. Reoperation rates however were increased with HHR, while GORD rates improved compared to LSG alone. For LRYGB, in all 5 studies, concurrent procedures were concluded to be safe and effective, with no increase in mortality, length of stay, readmission and reoperation rates. Higher complication rates were observed compared to LSG with HHR. Among LAGB studies, all 4 studies were concluded to be safe and effective with no adverse outcomes on mortality, length of stay and GORD rates. Reoperation rates from pouch dilatation and gastric prolapse were also observed to decrease. Conclusion Concurrent HHR with BS appears to be safe and effective. Assessment of BS warrants the consideration of concurrent HHR depending on specific patient case and the surgeon's preference.

OC-080 A NOVEL SURGICAL APPROACH, THE DOUBLE TRACT RECONSTRUCTION IN TREATING FAILED RE-DO FUNDOPLICATION

Abstract Aim Recurrence of hiatal hernia may occur in up to 70% of patients. Failure is defined subjectively as recurrence of symptoms and objectively by imaging or pH studies, which can diagnose recurrent hiatal hernia, wrap disruption, and/or reflux disease. Approximately 25% of patients need partial or subtotal esophagectomy - mainly secondarily to scar formation and fibrosis at the hiatus site. Our aim is to report the early results of a novel double tract reconstruction in treating failed re-do fundoplication Materials and methods Retrospective review of prospectively collected data on patients who had undergone salvage operation of failed re-do fundoplication related to demographics, operative details, surgical and clinical outcomes as well as patient satisfaction. Results Conclusion Double tract reconstruction appears a suitable option in treating symptomatic recurrently failed hiatal hernia repair especially after the second or third recurrence with disruption of the anatomy and scarring of gastroesophageal junction.

Efficacy of Sleeve Gastrectomy with Concomitant Hiatal Hernia Repair versus Sleeve-Fundoplication on Gastroesophageal Reflux Disease Resolution: Systematic Review and Meta-Analysis.

(1) Background: There is still disagreement over how sleeve gastrectomy (SG) affects gastroesophageal reflux disease (GERD). The debate regarding the best option for patients undergoing bariatric surgery who are also affected by GERD and/or hiatal hernia continues to divide the community of bariatric surgeons. While concomitant hiatal hernia repair (SG + HHR) has been proposed as a means of reducing the risk of GERD following SG with varying degrees of success, the addition of a fundoplication (SG + FP) has been suggested in recent years as a way to improve the lower esophageal sphincter's competency. The aim of this study is to systematically review and meta-analyze the efficacy of SG + HHR versus SG + FP on GERD remission in patients with obesity. (2) Methods: A systematic review of the literature was conducted, and studies analyzing the effects of SG + HHR versus SG + FP on postoperative GERD were included. The methodological quality of included trials was evaluated. The primary outcome was postoperative GERD rate, erosive esophagitis, and 12-month weight loss. Secondary outcomes included postoperative complications and mortality. The PRISMA guidelines were used to carry out the present systematic review (PROSPERO Registration Number: CRD42023405600). (3) Results: Fifteen articles with a total of 1164 patients were included in the meta-analysis; 554 patients underwent SG + HHR while 610 underwent SG + FP. In the SG + HHR group, 58.5 ± 28.9% of subjects presented clinical GERD symptoms compared to 20.4 ± 17.5% postoperatively (p < 0.001). In the SG + FP group, 64.8 ± 39.4% were affected by GERD preoperatively compared to only 5 ± 8.1% postoperatively (p < 0.001). SG + FP patients had a significantly greater GERD remission compared to SG + HHR (p < 0.001). Weight loss was similar between groups (p = 0.125). The rate of leaks was 0.18% and 0.33% in the SG + HHR and SG + FP, respectively (p = 0.657), while perforations were significantly higher after SG + FP compared to the SG + HHR group (3.1% versus 0%, p = 0.002). The mortality rate was significantly greater in the SG + FP group (0.5% versus 0%, p = 0.002). (4) Conclusions: This study revealed that both SG with concomitant HHR and sleeve-fundoplication are effective in terms of reflux resolution and weight outcomes, with superiority of SG + FP in terms of GERD control, despite a greater overall complication rate. Both strategies can therefore be suggested as a suitable alternative variant to a conventional SG in subjects with obesity and concomitant hiatal hernia and/or GERD. Studies with extended follow-up and direct comparisons of these surgical approaches to conventional SG are warranted.

Implementation and Effectiveness of Opioid Prescribing Guidelines After Hiatal Hernia Repair

IntroductionWe defined institutional opioid prescribing patterns, established prescribing guidelines, and evaluated the adherence to and effectiveness of these guidelines in association with opioid prescribing after hiatal hernia repair (HHR). MethodsA retrospective chart review was completed for patients who underwent transthoracic (open) or laparoscopic HHR between January and December 2016. Patient-reported opioid use after surgery was used to establish prescribing recommendations. Guideline efficacy was then evaluated among patients undergoing HHR after implementation (August 2018 to June 2019). Data are reported in oral morphine equivalents (OMEs). ResultsThe initial cohort included n = 87 patients (35 open; 52 laparoscopic) with a 68% survey response rate. For open repair, median prescription size was 338 mg OME (interquartile range [IQR] 250-420) with patient-reported use of 215 mg OME (IQR 78-308) (P = 0.002). Similarly, median prescription size was 270 mg OME (IQR 200-319) with patient-reported use of 100 mg OME (IQR 4-239) (P < 0.001) for laparoscopic repair. Opioid prescribing guidelines were defined as the 66th percentile of patient-reported opioid use. Postguideline implementation cohort included n = 108 patients (36 open; 72 laparoscopic). Median prescription amount decreased by 54% for open and 43% laparoscopic repair, with no detectable change in the overall refill rate after guideline implementation. Patient education, opioid storage, and disposal practices were also characterized. ConclusionsEvidence-based opioid prescribing guidelines can be successfully implemented for open and laparoscopic HHR with a high rate of compliance and without an associated increase in opioid refills.

American Foregut Society White Paper on Transoral Incisionless Fundoplication

Gastroesophageal reflux disease (GERD) is a chronic disease on a spectrum that has an array of management options ranging from lifestyle changes, acid suppressive therapy to laparoscopic anti-reflux surgery (LARS). Transoral incisionless fundoplication (TIF) is an endoscopic procedure in the management of GERD that re-establishes and augments the gastroesophageal flap valve (GEFV). TIF is appropriate for patients that do not have a hiatal hernia greater than 2 cm. Patients with a hiatal hernia greater than 2 cm have the option to have either a conventional LARS (laparoscopic hiatal hernia repair with complete or partial fundoplication) or a concomitant laparoscopic hiatal hernia repair with TIF, known as concomitant TIF (cTIF). This white paper summarizes the published outcome data for TIF 2.0 and cTIF to date and outline the best practice approaches including patient assessment, selection, and management for TIF and cTIF.

PO-04-075 TRANSVENOUS CARDIAC DEFIBRILLATOR WITHOUT INTERACTION WITH THE MAGNETIC TITANIUM BEADS SYSTEM FOR GASTROESOPHAGEAL REFLUX DISEASE

Gastroesophageal reflux is increasingly treated with LINX®, a flexible bracelet of magnetic titanium beads (not MRI compatible) that is laparoscopically implanted to wrap around the gastroesophageal junction for providing tone/support aiding passive relaxation of a weak lower esophageal sphincter with peristalsis. The FDA currently cautions against concurrent use of the LINX® system with cardiac implantable electronic devices (CIEDs) given that the risk of electromagnetic interference (EMI) is unknown, and safety has not been established. We assessed the safety of a transvenous ICD in a patient with the LINX® system. Case Report 59 year old male who previously had the LINX® system implanted after hiatal hernia repair for refractory reflux. Shortly after, he was then diagnosed with apical hypertrophic cardiomyopathy with obstruction (NYHA Class I, genetic testing revealed VUS in CSRP3). Given non-sustained VT on cardiac event monitoring, family history of sudden cardiac death (SCD) and late gadolinium enhancement on cardiac magnetic resonance imaging with a calculated 5-year SCD risk 4.1%, he was recommended ICD implantation for primary prevention. Patient underwent an uneventful transvenous dual chamber defibrillator implantation. Although we do not routinely perform (DFT) testing at our institution, given the coexisting LINX® system in close proximity to the RV lead, we elected to proceed with DFT Testing, which was successful (1 induction: T-wave shock from sinus to VF, 30J delivered successfully to sinus with 7s charge time, no ATP, 70 ohms impedance). Patient underwent routine remote device interrogations and at 1-year follow up (which included an in-person device interrogation), continues to have normal lead parameters (sensing, impedance, threshold), minimal atrial or ventricular pacing, and no recurrent arrhythmias including NSVT (was started on verapamil). Specifically, patient received no inappropriate shocks, and no high frequency noise episodes were detected. We present the first case report of a patient who had a concomitant dual chamber ICD that was implanted shortly after a LINX device placement. We demonstrate normal DFTs at implant and no device interaction at 1 year follow-up, suggesting that ICD implantation without removal of the LINX device might be reasonable. Decision-making for cardiac device implantation decisions in such patients should consider additional theoretical risks until additional data with more patients is available.

Milky fluid from where? You are about to find out…

Traumatic chylothorax most commonly occurs after thoracic surgeries with a few cases reported in patients after abdominal surgery. Effusions usually are caused by a pleural reaction during the postoperative period. However, this can also occur from disruption of the thoracic duct during the surgical procedure. The initial approach is conservative with supportive measures, including drainage by ultrasound-guided thoracentesis and diet modification, and surgery is rarely needed. Having a medical history preceding abdominal surgery is always important to consider the possibility of a pancreatic pleural fistula, which can be excluded by an abdominal computed tomography. Lymphangiography is considered the gold standard diagnostic tool, but its use is limited to cases unresponsive to conservative measures. In this patient, a lymphangiography or surgical intervention was not performed since the patient improved after initial management with no recurrent pleural effusion. A new pleural effusion after abdominal surgery must include chylothorax in the differential diagnosis.Keywords: Traumatic chylothorax, hiatal hernia repair, thoracic duct, lymphangiography, abdominal computed tomography

Diagnosis and management of thoracic endometriosis syndrome: Case report

Introduction: While the diagnosis of endometriosis is relatively common, thoracic endometriosis is a rare manifestation. Thoracic Endometriosis Syndrome (TES) most commonly presents with pneumothorax, 3% which are bilateral, making this case unique in the already limited breadth of TES with catamenial hemopneumothorax. Additionally, this patient had laboratory values constant with ovarian suppression yet continued menses and recurrent hemopneumothorax, necessitating surgical intervention. We propose that with this severity of disease a combination of surgical intervention and hormonal therapy is the ideal approach, providing the lowest rate of recurrence. Case description: A 33 year old woman with 2-day history of chest pain and shortness of breath with heavy menstrual cycles and significant dysmenorrhea. A chest radiograph and computed tomography scan revealed right-sided pneumothorax and bilateral hemothoraces with left-sided diaphragmatic hernia. Video-assisted thoracoscopic surgery confirmed sanguinous pleural effusions and biopsy proven endometriotic lesions. The patient was started on a gonadotropin-releasing hormone agonist and experienced short-interval recurrence of her symptoms. An aromatase inhibitor was added to her regimen and she underwent a left diaphragmatic hernia repair. Conclusions: The recurrence of symptoms despite complete hypothalamic-pituitary-ovarian axis suppression, in addition to the surgical requirements and findings make this case unique in the already limited breadth of thoracic endometriosis syndrome with catamenial hemopneumothorax.

Laparoscopic diaphragm repair with bioabsorbable mesh in congenital and acquired diaphragmatic hernia

Background and Aim: Congenital or acquired diaphragmatic hernias are both possible. The present study aimed to investigate the superiority of laparoscopic surgery over open repair of congenital diaphragmatic hernias with bioabsorbable mesh in congenital and acquired diaphragmatic hernia. Patients and Methods: This retrospective study was conducted on 7 diaphragmatic hernia cases in the General Surgery Unit of Federal Government Polyclinic Hospital, Islamabad from January 2015 to December 2022. Diaphragmatic hernia was diagnosed and confirmed on CT scan. Patients with Bochdalek hernia (BH), right-sided eventration of diaphragm, and left eventration of diaphragm (ED) cases were enrolled. Individual demographic details, clinical manifestations, hernia description, treatment modalities, and complications were recorded. Results: The overall mean age was 42 years with an age range 30-62 years. Of the total cases, there were 6 (85.7%) male and 1 (14.3%) female. The incidence of Bochdalek hernia (BH), left-sided ED, and right-sided ED was 2 (28.6%), 4 (57.1%), and 1 (14.3%) respectively. The major defect on left and right side was 15× 7 cm and 15× 8 cm respectively.

Evolution of Inguinal Hernia Publications: A Bibliometric Analysis from 1980 to 2021.

BACKGROUND Despite the increasing number of studies published worldwide focusing on inguinal hernia, a major condition in the surgical field that affects the quality of life of many patients, a bibliometric study on inguinal hernia is yet to be conducted. The present study aimed to analyze the scientific articles published on inguinal hernia using statistical methods. MATERIAL AND METHODS Articles published between 1980 and 2021 on inguinal hernia were downloaded from the Web of Science database and analyzed using statistical methods. RESULTS A total of 11 761 publications were found. The top 5 contributors to the literature were the United States (n=2109, 27%), Germany (563, 6.7%), United Kingdom (595, 5.7%), Turkey (415, 5.3%), and Japan (388, 4.9%). The top 3 most influential journals by average number of citations per article were Annals of Surgery (citations: 67.4), British Journal of Surgery (citations: 49.9), and Surgical Clinics of North America (citations: 43.2). CONCLUSIONS In the current comprehensive bibliometric study on inguinal hernia, which has demonstrated an upward trend in the number of articles published recently, we present a summary of 7810 articles published from 1980 to 2021. According to the results of the analysis conducted to identify trending topics, the keywords studied in recent years are believed to include pediatric, outcomes, minimally invasive surgery, robotic, incisional hernia, umbilical hernia, chronic pain, obesity, bariatric surgery, NSQIP, seroma, surgical site infection, abdominal wall reconstruction, ventral hernia repair, and hiatal hernia repair.

Laparoscopic large hiatus hernia repair with mesh reinforcement versus suture cruroplasty alone: a systematic review and meta-analysis.

To compare the difference in outcomes in laparoscopic large hiatus hernia (LHH) repair using suture-based and mesh-based repair techniques. A systematic search of articles was conducted in PubMed, Medline and Embase using the PRISMA guidelines. Studies comparing recurrences and reoperations in those patients with large hiatal hernia repair (> 30% stomach in the chest, > 5cm hiatal defect, hiatal surface area > 10 cm2) who had mesh vs no mesh were assessed quantitatively. The impact of mesh on significant intraoperative/postoperative surgical complications was qualitatively assessed. Pooled data included six randomized controlled trials and thirteen observational studies with 1670 patients (824 with no mesh, 846 with mesh). There was a significant reduction in the total recurrence rate with mesh (OR 0.44, 95% CI 0.25-0.80, p = 0.007). Mesh use did not cause significant reduction in recurrences > 2cm (OR 0.94, 95% CI 0.52-1.67, p = 0.83) or in reoperation rates (OR 0.64, 95% CI 0.39-1.07, p = 0.09). None of the specific meshes assessed were found to be superior in the reduction of recurrence or reoperation rates. Cases of mesh erosion with eventual foregut resection were noted and were associated with synthetic meshes only. Mesh reinforcement seemed protective against total recurrence in LHH although this has to be interpreted with caution given the level of heterogeneity introduced by the inclusion of observational studies in the analysis. There was no significant reduction in large recurrences (> 2cm) or reoperation rate. If the synthetic mesh is to be used patients need to be informed of the risk of mesh erosion.

Hiatus hernia repair with a new-generation biosynthetic mesh: a 4-year single-center experience

BackgroundMesh augmentation is a highly controversial adjunct of hiatus hernia (HH) surgery. The current scientific evidence remains unclear and even experts disagree on indications and surgical techniques. With an aim to avoid the downsides of both non-resorbable synthetic and biological materials, biosynthetic long-term resorbable meshes (BSM) have recently been developed and are becoming increasingly popular. In this context, we aimed at assessing outcomes after HH repair with this new generation of mesh at our institution.MethodsFrom a prospective database, we identified all consecutive patients that underwent HH repair with BSM augmentation. Data was extracted from electronic patient charts of our hospital information system. Endpoints of this analysis included perioperative morbidity, functional results and recurrence rates at follow-up.ResultsBetween December 2017 and July 2022, 97 patients (elective primary cases n = 76, redo cases n = 13, emergency cases n = 8) underwent HH with BSM augmentation. Indications in elective and emergency cases were paraesophageal (Type II–IV) HH in 83%, and large Type I HH in 4%. There was no perioperative mortality, and overall (Clavien–Dindo ≥ 2) and severe (Clavien–Dindo ≥ 3b) postoperative morbidity was 15% and 3%, respectively. An outcome without postoperative complications was achieved in 85% of cases (elective primary surgery 88%, redo cases 100%, emergencies cases 25%). After a median (IQR) postoperative follow-up of 12 months, 69 patients (74%) were asymptomatic, 15 (16%) reported improvement, and 9 (10%) had clinical failure, of which 2 patients (2%) required revisional surgery.ConclusionOur data suggest that HH repair with BSM augmentation is feasible and safe with low perioperative morbidity and acceptable postoperative failure rates at early to mid-term follow-up. BSM may be a useful alternative to non-resorbable materials in HH surgery.

Gastric remnant perforation after single anastomosis gastric bypass

Introduction: Acute perforation of gastric remnants after single anastomosis gastric bypass are scarcely reported in the literature. The leak of gastrointestinal contents into the abdomen increases morbidity and if not promptly recognized can lead to mortality from sepsis. Case Report: A 42-year-old male developed abdominal pain and fever after laparoscopic removal of adjustable gastric band, hiatus hernia repair, and single anastomosis gastric bypass. Computed tomography showed evidence of viscus perforation, bowel obstruction, and intra-abdominal infection. Operative findings suggested bowel obstruction of the afferent small bowel loop led to perforation at the gastric remnant staple line which was repaired primarily. Conclusion: Patients presenting with early sepsis after single anastomosis gastric bypass should be investigated with computed tomography. Gastrointestinal leaks should be promptly addressed with surgical washout, primary repair, and suture reinforcement.

A Narrative Review on Treatment of Giant Hiatal Hernia.

Background: The current gold standard of treatment for giant hiatal hernias (GHHs) is laparoscopic surgery. Laparoscopic surgery was performed as a less invasive procedure for paraesophageal hernias more than 25 years ago. Its viability and safety have almost all been shown. Materials and Methods: A review of recent and current studies' literature was done. Prospective randomized trials, systematic reviews, clinical reviews, and original articles were all investigated. The data were gathered in the form of a narrative evaluation. We examine the state of laparoscopic GHH repair today and outline the GHH management strategy. Results: In this review, we clear up misunderstandings of GHH and address bad habits that may have contributed to poor results, and we have consequently performed a methodical evaluation of GHH. First, we address subcategorizing GHH and provide criteria to define them. The preoperative workup strategies are then discussed, with a focus on any pertinent and frequent atypical symptoms, indications for surgery, timing of surgery, and the importance of surgery. The approach to the techniques and the logic behind surgery are then presented along with some important dissection techniques. Finally, we debate the role of mesh reinforcement and evaluate the data in terms of recurrence, reoperation rate, complications, and delayed stomach emptying. Finally, we suggest a justification for common postoperative investigations. Conclusions: Surgery is the only effective treatment for GHH at the moment. If the right operational therapy principles are applied, this is generally successful. There is a growing interest in laparoscopic paraesophageal hiatal hernia repair as a result of the introduction of laparoscopic antireflux surgery. Today's less invasive procedures provide a better therapeutic choice with a lower risk.
