Relationship between Helicobacter pylori Eradication and Barrett's Esophagus Elongation.

INTRODUCTION: Helicobacter pylori eradication therapy may worsen gastroesophageal reflux disease that is a significant risk factor for Barrett's esophagus. However, the relationship between eradication therapy and Barrett's esophagus remains controversial. This study evaluated the impact of Helicobacter pylori eradication on the lengthening of Barrett's esophagus. MATERIALS AND METHODS: We conducted a retrospective analysis of consecutive patients who successfully underwent Helicobacter pylori eradication between 2004 and 2017. Endoscopic images obtained before and after eradication therapy were compared for Barrett's esophagus length according to the Prague C&M criteria and the presence of reflux esophagitis based on the Los Angeles classification. RESULTS: A total of 340 patients were analyzed (mean age: 66.9 ± 12.9 years) for a median follow-up of 55 months (interquartile range: 29.8-89.3). At the initial endoscopic assessment, 187 patients (55%) had a hiatal hernia, and all patients had gastric atrophy (C-0 to I: 2%, C-II to III: 47%, O-I to III: 51%). Reflux esophagitis was detected in 7 patients (2%) before eradication and in 21 patients (6%) afterward, which was a significant increase (p = 0.007). Barrett's esophagus was identified in 69 patients (20%) before eradication, with a median length of C0M1. Elongation after treatment was observed in only 2 patients (0.6%). We observed no significant increase in either the prevalence (p = 0.85) or the median length (p = 0.5) of Barrett's esophagus. CONCLUSIONS: Only 0.6% of patients exhibited Barrett's esophagus lengthening after Helicobacter pylori eradication therapy, suggesting no significant impact of the treatment on the development or elongation of Barrett's esophagus.

Malpractice claims after antireflux surgery and paraesophageal hernia repair: a population-based analysis.

BACKGROUND: The complication rate of modern antireflux surgery or paraesophageal hernia repair is unknown, and previous estimates have been extrapolated from institutional cohorts. METHODS: A population-based retrospective cohort study of patient injury cases involving antireflux surgery and paraesophageal hernia repair from the Finnish National Patient Injury Centre (PIC) register between Jan 2010 and Dec 2020. Additionally, the baseline data of all the patients who underwent antireflux and paraesophageal hernia operations between Jan 2010 and Dec 2018 were collected from the Finnish national care register. RESULTS: During the study period, 5734 operations were performed, and the mean age of the patients was 54.9 ± 14.7 years, with 59.3% (n = 3402) being women. Out of all operations, 341 (5.9%) were revision antireflux or paraesophageal hernia repair procedures. Antireflux surgery was the primary operation for 79.9% (n = 4384) of patients, and paraesophageal hernia repair was the primary operation for 20.1% (n = 1101) of patients. A total of 92.5% (5302) of all the operations were laparoscopic. From 2010 to 2020, 60 patient injury claims were identified, with half (50.0%) of the claims being related to paraesophageal hernia repair. One of the claims was made due to an injury that resulted in a patient's death (1.7%). The mean Comprehensive Complication Index scores were 35.9 (± 20.7) and 47.6 (± 20.8) (p = 0.033) for antireflux surgery and paraesophageal hernia repair, respectively. Eleven (18.3%) of the claims pertained to redo surgery. CONCLUSIONS: The rate of antireflux surgery has diminished and the rate of paraesophageal hernia repair has risen in Finland during the era of minimally invasive surgery. Claims to the PIC remain rare, but claims regarding paraesophageal hernia repairs and redo surgery are overrepresented. Additionally, paraesophageal hernia repair is associated with more serious complications.

Hiatal hernia reporting: time to remove subjectivity?

INTRODUCTION: The size of a hiatal hernia (HH) is a key determinant of the approach for surgical repair. However, endoscopists will often utilize subjective terms, such as "small," "medium," and "large," without any standardized objective correlations. The aim of this study was to identify HHs described using objective axial length measurements versus subjective size allocations and compare them to their corresponding manometry and barium swallow studies. METHODS AND PROCEDURES: Retrospective chart reviews were conducted on 93 patients diagnosed endoscopically with HHs between 2017 and 2021 at Newton-Wellesley Hospital. Information was collected regarding their HH subjective size assessment, axial length measurement (cm), manometry results, and barium swallow readings. Linear regression models were used to analyze the correlation between the objective endoscopic axial length measurements and manometry measurements. Ordered logistic regression models were used to correlate the ordinal endoscopic and barium swallow subjective size allocations with the continuous axial length measurements and manometry measurements. RESULTS: Of the 93 endoscopy reports, 42 included a subjective size estimate, 38 had axial length measurement, and 12 gave both. Of the 34 barium swallow reads, only one gave an objective HH size measurement. Axial length measurements were significantly correlated with the manometry measurements (R2 = 0.0957, p = 0.049). The endoscopic subjective size estimates were also closely related to the manometry measurements (R2 = 0.0543, p = 0.0164). Conversely, the subjective size estimates from barium swallow reads were not significantly correlated with the endoscopic axial length measurements (R2 = 0.0143, p = 0.366), endoscopic subjective size estimates (R2 = 0.0481, p = 0.0986), or the manometry measurements (R2 = 0.0418, p = 0.0738). Mesh placement was significantly correlated to pre-operative endoscopic axial length measurement (p = 0.0001), endoscopic subjective size estimate (p = 0.0301), and barium swallow read (p = 0.0211). However, mesh placement was not significantly correlated with pre-operative manometry measurements (0.2227). CONCLUSIONS: Endoscopic subjective size allocations and objective axial length measurements are associated with pre-operative objective measurements and intra-operative decisions, suggesting both can be used to guide clinical decision making. However, including axial length measurements in endoscopy reports can improve outcomes reporting.

Personalized anti-reflux surgery: connecting GERD phenotypes in 690 patients to outcomes.

BACKGROUND: Anti-reflux operations are effective treatments for GERD. Despite standardized surgical techniques, variability in post-operative outcomes persists. Most patients with GERD possess one or more characteristics that augment their disease and may affect post-operative outcomes-a GERD "phenotype". We sought to define these phenotypes and to compare their post-operative outcomes. METHODS: We performed a retrospective review of a prospective gastroesophageal database at our institution, selecting all patients who underwent an anti-reflux procedure for GERD. Patients were grouped into different phenotypes based on the presence of four characteristics known to play a role in GERD: hiatal or paraesophageal hernia (PEH), hypotensive LES, esophageal dysmotility, delayed gastric emptying (DGE), and obesity. Patient-reported outcomes (GERD-HRQL, dysphagia, and reflux symptom index (RSI) scores) were compared across phenotypes using the Wilcoxon rank-sum test. RESULTS: 690 patients underwent an anti-reflux procedure between 2008 and 2022. Most patients underwent a Nissen fundoplication (302, 54%), followed by a Toupet or Dor fundoplication (205, 37%). Twelve distinct phenotypes emerged. Non-obese patients with normal esophageal motility, normotensive LES, no DGE, with a PEH represented the most common phenotype (134, 24%). The phenotype with the best post-operative GERD-HRQL scores at one year was defined by obesity, hypotensive LES, and PEH, while the phenotype with the worst scores was defined by obesity, ineffective motility, and PEH (1.5 ± 2.4 vs 9.8 ± 11.4, p = 0.010). There was no statistically significant difference in GERD-HRQL, dysphagia, or RSI scores between phenotypes after five years. CONCLUSIONS: We have identified distinct phenotypes based on common GERD-associated patient characteristics. With further study these phenotypes may aid surgeons in prognosticating outcomes to individual patients considering an anti-reflux procedure.

A trans-Canadian positive deviance seminar for paraesophageal hernia surgery: Reporting national postoperative outcomes and consensus recommendations.

BACKGROUND: The incidence of adverse events (AEs) and length of stay (LOS) varies significantly following paraesophageal hernia surgery. We performed a Canadian multicenter positive deviance (PD) seminar to review individual center and national level data and establish holistic perioperative practice recommendations. METHODS: A national virtual PD seminar was performed in October 2021. Recent best evidence focusing on AEs and LOS was presented. Subsequently, anonymized center-level AE and LOS data collected between 01/2017 and 01/2021 from a prospective, web-based database that tracks postoperative outcomes was presented. The top two performing centers with regards to these metrics were chosen and surgeons from these hospitals discussed elements of their treatment pathways that contributed to these outcomes. Consensus recommendations were then identified with participants independently rating their level of agreement. RESULTS: Twenty-eight surgeons form 8 centers took part in the seminar across 5 Canadian provinces. Of the 680 included patients included, Clavien-Dindo grade I and II/III/IV/V complications occurred in 121/39/12/2 patients (17.8%/5.7%/1.8%/0.3%). Respiratory complications were the most common (effusion 12/680, 1.7% and pneumonia 9/680, 1.3%). Esophageal and gastric perforation occurred in 7 and 4/680, (1.0% and 0.6% respectively). Median LOS varied significantly between institutions (1 day, range 1-3 vs. 7 days, 3-8, p < 0.001). A strong level of agreement was achieved for 10/12 of the consensus statements generated. CONCLUSION: PD seminars provide a supportive forum for centers to review best evidence and experience and generate recommendations based on expert opinion. Further research is ongoing to determine if this approach effectively accomplishes this objective.

Short-term results of laparoscopic anti-reflux surgery with the RefluxStop device in patients with gastro-esophageal reflux disease and ineffective esophageal motility.

PURPOSE: In gastro-esophageal reflux disease (GERD) requiring surgical treatment, concomitant ineffective esophageal motility (IEM) is a decisive factor in surgical planning, due to concern regarding dysphagia. Anti-reflux surgery with the RefluxStop device is a promising technique. We assessed initial feasibility and clinical outcomes of RefluxStop surgery in patients with GERD and IEM. METHODS: Retrospective analysis of patients with GERD, hiatal hernia (HH), and IEM, who underwent surgery with RefluxStop at our institution and achieved 12-month follow-up. Technique feasibility was assessed, in addition to symptom resolution (GERD-HRQL questionnaire), adverse events, HH recurrence, dysphagia, and patient satisfaction. Placement of the device was confirmed by video fluoroscopy on postoperative day 1, and at 3 and 12 months. RESULTS: Between June 2020 and November 2022, 20 patients with IEM underwent surgery with RefluxStop and completed 12-month follow-up. All patients reported typical symptoms of GERD, and 12 had preoperative dysphagia. The median HH length was 4.5 cm (IQR, 3.75-5). The median operating time was 59.5 min (IQR, 50.25-64) with no implant-related intra- or postoperative complications. No HH recurrence was observed. One patient reported persistent left-sided thoracic pain at 11 months post-surgery, which required diagnostic laparoscopy and adhesiolysis. Three patients reported severe postoperative dysphagia: balloon dilatation was performed towards resolution. The mean GERD-HRQL scores improved (from 40.7 at baseline to 4.8 at 3 months and 5.7 at 12 months (p <0.001)). CONCLUSION: RefluxStop surgery was feasible and offered effective treatment for this group of patients with GERD and IEM. All patients had complete resolution or significant improvement of GERD symptoms, and 90% of them were satisfied with their quality of life 1 year after surgery.

Functional results after hiatal repair and gastropexy without fundoplication in patients with paraoesophageal hernia.

PURPOSE: Paraoesophageal hernias (PEH) are associated with a high complication rate and often occur in elderly and fragile patients. Surgical gastropexy without fundoplication is an accepted alternative procedure; however, outcomes and functional results are rarely described. Our study aims to evaluate short-term outcomes and the long-term quality of life after gastropexy as treatment for PEH. METHODS: Single center cohort analysis of all consecutive patients who underwent gastropexy for PEH without fundoplication. Postoperative outcomes and functional results were retrospectively collected. Reflux symptoms developed postoperatively were reported using the validated quality of life questionnaire: GERD-Health Related Quality of Life Qestionnaire (GERD-HRQL). RESULTS: Thirty patients (median age: 72 years (65-80)) were included, 40% classified as ASA III. Main PEH symptoms were reflux (63%), abdominal/thoracic pain (47%), pyrosis (33%), anorexia (30%), and food blockage (26%). Twenty-six laparoscopies were performed (86%). Major complications (III-IVb) occurred in 9 patients (30%). Seven patients (23%) had PEH recurrence, all re-operated, performing a new gastropexy. Median follow-up was 38 (17-50) months. Twenty-two patients (75%) reported symptoms resolution with median GERD-HRQL scale of 4 (1-6). 72% (n = 21) reported operation satisfaction. GERD-HRQL was comparable between patients who were re-operated for recurrence and others: 5 (2-19) versus 3 (0-6), p = 0.100. CONCLUSION: Gastropexy without fundoplication was performed by laparoscopy in most cases with acceptable complications rates. Two-thirds of patients reported symptoms resolution, and long-term quality-of-live associated to reflux symptoms is good. Although the rate of PEH recurrence requiring a new re-intervention remained increased (23%), it does not seem to affect long-term functional results.

A systematic review of Sandifer syndrome in children with severe gastroesophageal reflux.

PURPOSE: Sandifer syndrome (SS), which combines gastroesophageal reflux (GER) and a neurological or psychiatric disorder, is an uncommon condition that often takes a long time to diagnosis. We aimed to systematically review available papers regarding SS. METHODS: After presenting our two cases of SS, we systematically reviewed articles published in MEDILINE/PubMed, Cochrane Library, and Web of Science. RESULTS: The meta-analysis included 54 reported cases and 2 of our own cases. Our results showed that all cases achieved symptom improvement with appropriate treatment for GER. Notably, 19 of the 56 cases exhibited anatomical anomalies, such as hiatal hernia and malrotation. Significantly more patients with than without anatomical anomalies required surgery (p < 0.001). However, 23 of the 29 patients without anatomical anomalies (79%) achieved symptom improvement without surgery. Patients who did not undergo surgery had a median (interquartile range) duration to symptom resolution of 1 (1-1) month. CONCLUSION: The primary care providers should keep SS in the differential diagnosis of patients presenting with abnormal posturing and no apparent neuromuscular disorders. Fundoplication may be effective especially for patients with anatomical anomalies or those whose symptoms do not improve after more than 1 month with nonsurgical treatment.

[A Case of Early Gastric Cancer with Esophageal Hiatal Hernia Treated by Laparoscopic Gastrectomy for Cancer and Repair of Hiatal Hernia].

We report a successful case of gastric cancer with esophageal hiatal hernia treated by laparoscopic surgery. The patient was a 75-year-old woman who was referred to our hospital with a diagnosis of early gastric cancer with esophageal hiatal hernia. Laparoscopic distal gastrectomy with lymph node dissection and esophageal hiatal hernia repair using primary suture method without mesh were performed simultaneously. She had a good postoperative course without the recurrence of both cancer and hernia.

Is it meaningful to add mesh reinforcement to laparoscopic fundoplication for esophageal hiatal hernias in the patients with high risk of hiatal hernia recurrence?

BACKGROUND: While laparoscopic fundoplication is a standard surgical procedure for patients with esophageal hiatal hernias, the postoperative recurrence of esophageal hiatal hernias is a problem for patients with giant hernias, elderly patients, or obese patients. Although there are some reports indicating that reinforcement with mesh is effective, there are differing opinions regarding the use thereof. The aim of this study is to investigate whether mesh reinforcement is effective for laparoscopic fundoplication in patients with esophageal hiatus hernias. METHODS: The subjects included 280 patients who underwent laparoscopic fundoplication as the initial surgery for giant esophageal hiatal hernias, elderly patients aged 75 years or older, and obese patients with a BMI of 28 or higher, who were considered at risk of recurrent hiatal hernias based on the previous reports. Of the subject patients, 91 cases without mesh and 86 cases following the stabilization of mesh use were extracted to compare the postoperative course including the pathology, symptom scores, surgical outcome, and recurrence of esophageal hiatus hernias. RESULTS: The preoperative conditions indicated that the degree of esophageal hiatal hernias was high in the mesh group (p = 0.0001), while the preoperative symptoms indicated that the score of heartburn was high in the non-mesh group (p = 0.0287). Although the surgical results indicated that the mesh group underwent a longer operation time (p < 0.0001) and a higher frequency of intraoperative complications (p = 0.037), the rate of recurrence of esophageal hiatal hernia was significantly low (p = 0.049), with the rate of postoperative reflux esophagitis also tending to be low (p = 0.083). CONCLUSIONS: Mesh reinforcement in laparoscopic fundoplication for esophageal hiatal hernias contributes to preventing the recurrence of esophageal hiatal hernias when it comes to patient options based on these criteria.

Long-term results after laparoscopic revision fundoplication: a retrospective, single-center analysis in 194 patients with recurrent hiatal hernia.

BACKGROUND: After laparoscopic fundoplication, 10-20% of patients experience symptom recurrence-often due to resurgence of the hiatal hernia. The standard surgical treatment for such cases remains laparoscopic revision fundoplication. However, there is little data on the time frame and anatomic patterns of failed fundoplications. Additionally, few large studies exist on the long-term efficacy and safety of laparoscopic revision fundoplication. METHODS: In a single-center, retrospective analysis of 194 consecutive revision fundoplications for recurrent reflux disease due to hiatal hernia, we collected data on time to failure and patterns of failure of the primary operation, as well as on the efficacy and safety of the revision. RESULTS: The median time to failure of the primary fundoplication was 3 years. Most hiatal defects were smaller than 5 cm and located anteriorly or concentric around the esophagus. Laparoscopic redo fundoplication was technically successful in all cases. The short-term complication rate was 9%, mainly dysphagia requiring endoscopic intervention. At a mean follow-up of 4.7 years, 77% of patients were symptom-free, 14% required daily PPI, and 9% underwent secondary revision. Cumulative failure rates were 9%, 23%, and 31% at 1, 5, and 10 years. CONCLUSION: The majority of failed fundoplications occur within 3 years of primary surgery, with most patients exhibiting anterior or concentric defects. For these patients, laparoscopic revision fundoplication is a safe procedure with a low rate of short-term complications and satisfactory long-term results.

Intermittent Hiatus Hernia on High-Resolution Manometry Associates With Abnormal Reflux Burden Similar to Persistent Hiatus Hernia.

INTRODUCTION: Hiatus hernia is characterized by axial separation between the lower esophageal sphincter and the crural diaphragm, and higher reflux burden. Impact on reflux is unclear if such separation is intermittent rather than persistent. METHODS: Reflux burden off antisecretory therapy was compared between no hernia (n = 357), intermittent hernia (n = 42), and persistent hernia (n = 155) after review of consecutive high-resolution manometry and reflux monitoring studies. RESULTS: Proportions with pathologic acid exposure was similar between intermittent and persistent hernia (45.2% vs 46.5%, respectively), and both were significantly different from no hernia (28.7%, P ≤ 0.002). DISCUSSION: Intermittent hiatus hernias are clinically relevant in gastroesophageal reflux pathophysiology.

Safety and Feasibility of Performing Antireflux Procedures at a Safety Net Hospital.

INTRODUCTION: One-half of Americans have limited access to health care; these patients often receive care through safety net hospitals, which are associated with worse medical outcomes. This study aims to compare the outcomes of patients who received foregut surgery at a safety net hospital to those at a private or university hospital. We hypothesized that patients treated at the safety net hospital will have a greater rate of radiographic recurrence and reoperations. METHODS: A retrospective study was conducted on patients who underwent hiatal hernia repair or fundoplication for gastroesophageal reflux disease at an affiliated safety net, private, or university hospital from June 2015 to May 2020. The primary outcome was radiographic recurrence. The secondary outcomes included reoperation and symptom recurrence. Analysis was performed using analysis of variance, chi-square, and logistic regression. RESULTS: A total of 499 patients were identified: 157 at a safety net hospital, 233 at a private hospital, and 119 at a university hospital. The median (interquartile range) follow-up was 16 (13) mo. The safety net hospital treated more Hispanics, females, and patients with comorbidities. Large hiatal hernias were more common at the safety net and private hospitals. Robotic surgery was more frequently at the university hospital. There was no difference in radiographic recurrence (13.4% versus 19.7% versus 17.6%; P = 0.269), reoperation (3.8% versus 7.2% versus 6.7%; P = 0.389), or postoperative dysphagia (15.3% versus 12.6% versus 15.1%; P = 0.696). On logistic regression, there were no differences in outcomes among institutions. CONCLUSIONS: This study suggests that despite the challenges faced at safety net hospitals, it could be feasible to safely perform minimally invasive foregut surgery with similar outcomes to private and university hospitals.

Long-Term Clinical Course after Successful Initial Treatment in Patients with Mild Erosive Esophagitis: A Prospective Follow-Up Study.

INTRODUCTION: This study aimed to investigate the clinical course of patients with healed mild erosive esophagitis and clarify the predictive factors for continuous treatment. METHOD: Fifty-one patients with mild erosive esophagitis who confirmed mucosal healing by endoscopy after initial treatment with vonoprazan (VPZ) were enrolled. The patients continued subsequent treatment of their choice: maintenance therapy with VPZ 10 mg (n = 15), on-demand therapy with VPZ 20 mg (n = 19), or no medication (n = 17). Each patient was prospectively followed up for over 2 years, and the treatment was switched to other options appropriately according to their symptoms. RESULTS: During the mean follow-up period of 3.1 years (range: 2.0-3.9 years), 2 patients who chose maintenance therapy switched to on-demand therapy. One patient who chose on-demand therapy switched to maintenance therapy, while 3 patients switched to no medication. Recurrence of symptoms occurred in 9 patients who chose no medication. They were administered maintenance therapy and five of them were subsequently switched to on-demand therapy. Ultimately, the proportion of patients receiving each treatment was 35.3% (18/51) for maintenance therapy, 43.1% (22/51) for on-demand therapy, and 21.6% (11/51) for no medication. A predictive factor for the need for continuous treatment was the presence of esophageal hiatal hernia (odds ratio: 6.03, 95% confidence interval: 1.43-25.3, p = 0.014). CONCLUSION: Among patients with healed mild erosive esophagitis, 78.4% required continuous treatment with VPZ, while 21.6% remained symptom free with no medication. On-demand therapy was the most common treatment, and continuous treatment may be recommended for patients with esophageal hiatal hernia.

Similar hospital profits with robotic-assisted paraesophageal hiatal hernia repair, despite higher or supply costs.

INTRODUCTION: Robotic-assisted laparoscopic surgery has emerged as an alternative to traditional laparoscopy and may offer some clinical benefits when performing complex hiatal hernia repairs. Many institutions may choose to not invest in robotic surgery because of perceived higher costs, and when they already have proficient laparoscopic surgeons. We hypothesized that the robotic approach would yield lower profits overall due to higher supply costs, while offering comparable outcomes to the traditional laparoscopic approach. METHODS: Financial and outcomes data from a single quaternary academic center was retrospectively reviewed from a prospectively collected database from July 2020 to May 2021. Laparoscopic hiatal hernia repairs and robotic-assisted repairs were compared for metrics including length of stay, operative time, hospital and supply cost, payments, and profits. Metrics of these two groups were compared using t-test analyses with significance set to p < 0.05. RESULTS: Seventy-three patients were included with 31 in the robotic group (42.5%) and 42 in the laparoscopic group (57.5%). There were no significant differences in length of stay (robotic mean 2.0 days, laparoscopic 2.55 days, p = 0.09) or operative time (257.6 min vs 256.7 min, p = 0.48) between the two approaches. The robotic approach was associated with higher supply costs ($2,655 vs $2,028, p < 0.001) and patient charges ($63,997 vs $56,276, p < 0.05). Despite higher costs associated with robotics, hospital profits were not different between the two groups ($7,462 vs $7,939, p = 0.42). CONCLUSION: Despite higher supply costs and charges for robotic-assisted hiatal hernia repair, hospital profits were similar when comparing robotic and laparoscopic approaches. Short-term clinical outcomes were also similar. Programs should do their own analysis to understand their individual cost issues.

Laparoscopic revision paraesophageal hernia repair: a 16-year experience at a single institution.

BACKGROUND: Laparoscopic paraesophageal hernia repair (PEHr) is a safe and effective procedure for relieving foregut symptoms associated with paraesophageal hernias (PEH). Nonetheless, it is estimated that about 30-50% of patients will have symptomatic recurrence requiring additional surgical intervention. Revision surgery is technically demanding and may be associated with a higher rate of morbidity and poor patient-reported outcomes. We present the largest study of perioperative and quality-of-life outcomes among patients who underwent laparoscopic revision PEHr. METHODS: A retrospective review of all patients who underwent laparoscopic revision paraesophageal hernia repair between February 2003 and October 2019, at a single institution was conducted. All revisions of Type I hiatal hernias were excluded. The following validated surveys were used to evaluate quality-of-life outcomes: Reflux Symptom Index (RSI) and Gastroesophageal Reflux Disease Health-Related QOL (GERD-HRQL). Patient demographic, perioperative, and quality-of-life (QOL) data were analyzed using univariate analysis. RESULTS: One hundred ninety patients were included in the final analysis (63.2% female, 90.5% single revision, 9.5% multiple revisions) with a mean age, BMI, and age-adjusted Charlson score of 56.6 ± 14.7 years, 29.7 ± 5.7 kg/m2, and 2.04 ± 1.9, respectively. The study cohort consisted of type II (49.5%), III (46.3%), and IV hiatal hernia (4.2%), respectively. Most patients underwent either a complete (68.7%) or partial (27.7%) fundoplication. A Collis gastroplasty was performed in 14.7% of patients. The median follow-up was 17.6 months. The overall morbidity and mortality rate were 15.8% and 1.1%, respectively. The 30-day readmission rate was 9.5%. Additionally, at latest follow-up 47.9% remained on antireflux medication. At latest follow-up, there was significant improvement in mean RSI score (46.4%, p < 0.001) from baseline within the study population. Furthermore, there was no significant difference in QOL between patients who had a history of an initial repair only or history of revision surgery at latest review. The overall recurrence rate was 16.3% with 6.3% requiring a surgical revision. CONCLUSION: Laparoscopic revision PEHr is associated with a low rate of morbidity and mortality. Revision surgery may provide improvement in QOL outcomes, despite the high rate of long-term antireflux medication use. The rate of recurrent paraesophageal hernia remains low with few patients requiring a second revision. However, longer follow-up is needed to better characterize the long-term recurrence rate and symptomatic improvements.

Transthoracic fundoplication using the Belsey Mark IV technique versus Nissen fundoplication: A systematic review and meta-analysis.

BACKGROUND: Nissen fundoplication is considered the cornerstone surgical treatment for hiatal hernia repair. Belsey Mark IV (BMIV) transthoracic fundoplication is an alternative approach that is rarely utilized in today's minimally invasive era. This study aims to summarize the safety and efficacy of BMIV and to compare it with Nissen fundoplication. METHODS: We searched MEDLINE, Scopus, and Cochrane Library databases for single arm and comparative studies published by March 31st, 2022, according to PRISMA statement. Inverse-variance weights were used to estimate the proportion of patients experiencing the studied outcome and random-effects meta-analyses were performed. RESULTS: 17 studies were identified, incorporating 2136 and 638 patients that underwent Belsey Mark IV or Nissen fundoplication, respectively. A total of 13.8% (95% CI: 9.6-18.6) of the patients that underwent fundoplication with the BMIV technique had non-resolution of their symptoms and 3.5% (95% CI: 2.0-5.4) required a reoperation. Overall, 14.8% (95% CI: 9.5-20.1) of the BMIV arm patients experienced post-operative complications, 5.0% (95% CI: 2.0-9.0) experienced chronic postoperative pain and 6.9% (95% CI: 3.1-11.9) had a hernia recurrence. No statistically significant difference was observed between Belsey Mark IV and Nissen fundoplication in terms of post-interventional non-resolution of symptoms (odds ratio [OR]: 1.49 [95% Confidence Interval (95%CI):0.6-4.0]; p = 0.42), post-operative complications (OR:0.83, 95%CI: 0.5-1.5, p = 0.54) and in-hospital mortality (OR:0.69, 95%CI: 0.13-3.80, p = 0.67). Belsey Mark IV arm had significantly lower reoperation rates compared to Nissen arm (OR:0.28, 95%CI: 0.1-0.7, p = 0.01). CONCLUSIONS: BMIV fundoplication is a safe and effective but technically challenging. The BMIV technique may offer benefits to patients compared to the laparoscopic Nissen fundoplication. These benefits, however, are challenged by the increased morbidity of a thoracotomy.

A 13-year experience with biologic and biosynthetic absorbable mesh reinforced laparoscopic paraesophageal hernia repair.

BACKGROUND: Mesh reinforced cruroplasty during laparoscopic paraesophageal hernia repair remains controversial due to wide variation in surgical technique and mesh composition. This study aims to review outcomes and rates of recurrence following laparoscopic paraesophageal hernia repair (LPEHR) with mesh reinforced cruroplasty utilizing absorbable mesh at a single institution. METHODS: A retrospective review of all patients who underwent LPEHR with mesh was performed. Medical records were reviewed for patient reported, radiographic or endoscopic evidence of recurrence, defined as > 2 cm of vertical intrathoracic stomach. If no studies were available for review, patients were considered to have no recurrence. Outcomes and mesh-related complications were also reviewed. RESULTS: Between 10/2008 and 9/2021, 473 patients underwent LPEHR with absorbable mesh; 1.3% type 2 hernias, 86.0% type 3 hernias, 12.7% type 4 hernias. Three types of mesh were used: initially biologic mesh (n = 83), then heavyweight synthetic bioabsorbable mesh (n = 261), and finally lightweight synthetic bioabsorbable mesh (n = 111). There were no significant differences in age, ASA, BMI, gender, smoking status, chronic steroid use, preoperative acid suppression, hernia type, or recurrent hernia between groups. There were no significant differences in 30-day postoperative outcomes. Reflux Symptom Index, GERD-HRQL, and Dysphagia Scores at 1- and 2-year postoperative timepoints were not significantly different. The overall recurrence rate was 16.7%, with no significant differences in recurrence rates between biologic, heavyweight or lightweight biosynthetic absorbable mesh through 2 years after surgery. A shorter median time to recurrence (10 months, p = 0.016) was seen in the lightweight group. CONCLUSION: LPEHR with absorbable mesh reinforced cruroplasty is feasible and safe, with equivalent patient-reported outcomes, including dysphagia, up to 2-years postop regardless of mesh choice. No significant differences in recurrence rates between biologic, heavyweight, or lightweight synthetic bioabsorbable mesh were seen up to 2 years after LPEHR.

Resolution and recurrence of anemia following repair of paraesophageal hernias.

BACKGROUND: Iron deficiency anemia is a common paraesophageal hernia (PEH) symptom and may improve after repair. When present, anemia has also been proposed to be associated with an increase in length of hospital stay, morbidity, and mortality after PEH repair. This study aimed to determine anemia-related factors in patients with PEH, the rate of anemia resolution after PEH repair, and the risk of anemia recurrence when repair failed. METHODS: We included patients who received a PEH repair between June 2019 and June 2020 and had 24 months of postoperative follow-up. Demographics and comorbidities were recorded. Anemia was defined as pre-operative hemoglobin values < 12.0 for females and < 13.0 for males, or if patients were receiving iron supplementation. Anemia resolution was determined at 6 months post-op. Length of hospital stay, morbidity, and mortality was recorded. Logistic regression and ANCOVA were used for binary and continuous outcomes respectively. RESULTS: Of 394 patients who underwent PEH repair during the study period, 101 (25.6%) had anemia before surgery. Patients with pre-operative anemia had larger hernia sizes (6.55 cm ± 2.77 vs. 4.34 cm ± 2.50; p < 0.001). Of 68 patients with available data by 6 months after surgery, anemia resolved in 36 (52.9%). Hernia recurred in 6 patients (16.7%), 4 of whom also had anemia recurrence (66.7%). Preoperative anemia was associated with a higher length of hospital stay (3.31 days ± 0.54 vs 2.33 days ± 0.19 p = 0.046) and an increased risk of post-operative all-cause mortality (OR 2.7 CI 1.08-6.57 p = 0.05). Fundoplication type (p = 0.166), gastropexy, or mesh was not associated with an increased likelihood of resolution (OR 0.855 CI 0.326-2.243; p = 0.05) (OR 0.440 CI 0.150-1.287; p = 0.05). CONCLUSIONS: Anemia occurs in 1 out of 4 patients with PEH and is more frequent in patients with larger hernias. Anemia is associated with a longer hospital stay and all-cause mortality after surgery. Anemia recurrence coincided with hernia recurrence in roughly two-thirds of patients.
