Concomitant hiatal hernia repair with transoral incisionless fundoplication for the treatment of refractory gastroesophageal reflux disease: a systematic review.

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. 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. 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%). 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.

How I Do It—Transoral Incisionless Fundoplication with Concomitant Hiatal Hernia Repair

AbstractTransoral incisionless fundoplication with concomitant hiatal hernia repair (cTIF) is an antireflux procedure that combines hiatal hernia repair with TIF. As such, it restores the antireflux barrier using a two-step, hybrid procedure utilizing both minimally invasive surgery and endoscopy in one operative procedure. In this article, we discuss the procedure as well as its role in the armamentarium of interventions for gastroesophageal reflux disease and outline technical details.

461. BARRETT'S ESOPHAGUS POST-ABLATION TRANSORAL INCISIONLESS FUNDOPLICATION (TIF) WITH OR WITHOUT HIATAL HERNIA REPAIR (CTIF):A PROSPECTIVE FEASIBILITY TRIAL

Abstract Transoral incisionless fundoplication without (TIF) or with concomitant hiatal hernia repair(cTIF) are treatment options for GERD. Lifelong PPI therapy is recommended for BE patients, even after endoscopic eradication therapy (EET), but concern for adverse effects of chronic PPI use has increased. Full barrier surgical therapy (Nissen fundoplication, magnetic sphincter augmentation) is a highly effective treatment for GERD but is associated with dysphagia and gas-bloat. We hypothesized that TIF/cTIF may be reasonable alternatives. AIM: We studied the safety and efficacy of TIF/cTIF in post-EET BE patients with refractory GERD symptoms or esophagitis despite PPI, and those averse to chronic PPI. METHODS: We prospectively enrolled BE patients with BMI <35 after successful EET (EMR, RFA, cryoablation) who underwent TIF (HH < 2cm, Hill grade ≤2) from Nov 2017-2020 or cTIF (HH ≥2cm, Hill grade ≥3) from Nov 2020-2022. Preoperative evaluation included baseline standardized GERD questionnaires, EGD, and selective pH testing and manometry. The primary outcome was GERD/LPRD symptom control. Secondary outcomes were presence of esophagitis, PPI use, patient satisfaction (rated as satisfied/neutral/dissatisfied), average duration of symptom control off PPI, failure rate, BE recurrence, and adverse events. RESULTS: To date, 30 patients have had TIF or cTIF (Table 1) after EET for LGD/HGD/ImCA (n=19) or no dysplasia + family history of BE/ECA, n=11). Median follow-up to date is 3 years (IQR 2-4, range 0.5-6). 22/30(76%) were asymptomatic on once/twice daily PPI at baseline but PPI averse. All TIFs/cTIFs were completed without serious adverse events. At 6 months post TIF/cTIF, GERD/LPRD symptom control was 86% (GERD-HRQL score) and 93% (Reflux Symptom Index score) (Fig 1B), esophagitis was absent in all patients, PPI discontinued or reduced to occasional use in 83% (Fig 1B), and acid exposure time was normal in 74%. At last follow-up, GERD and LPRD symptoms remained controlled in 93% and 96%, respectively, esophagitis absent in 95%, PPI discontinued or reduced in 71% (Fig 1D). Overall, the mean duration off PPI from TIF/cTIF was 30.4 months (range 4.4-72.5). Patient satisfaction improved from 43% at baseline, to 69% at 6 months, to 79% at last follow-up (Fig 1C). TIF/cTIF failure (defined as resumption of daily/twice daily PPI, symptom recurrence, and/or abnormal AET) was 9(32%), greater in TIF (50%) than cTIF (8%) (p=0.039). Median recurrent hiatal hernia length was 1(IQR 0-1.5). Nondysplastic BE recurrence noted in 1 patient treated with APC and TIF (3.3%). Dysphagia (10%) and gas bloat (7%) improved from baseline (37% and 20%, respectively). CONCLUSION: Transoral partial fundoplication is a safe and effective alternative to chronic PPI or full barrier surgical therapy in BE patients after EET. Surgical hiatal hernia repair (cTIF) provides added durability.

Hiatal Hernia Repair With Tension-Free Mesh or Crural Sutures Alone in Antireflux Surgery

Antireflux surgery is an effective treatment of gastroesophageal reflux disease (GERD), but the durability of concomitant hiatal hernia repair remains challenging. Previous research reported that the use of a mesh-reinforced, tension-free technique was associated with more dysphagia for solid foods after 3 years without reducing hiatal hernia recurrence rates compared with crural sutures alone, but the long-term effects of this technique have not been assessed. To assess the long-term anatomical and functional outcomes of using a mesh for hiatal hernia repair in patients with GERD. A double-blind, randomized clinical trial was performed at a single center (Ersta Hospital, Stockholm, Sweden) from January 11, 2006, to December 1, 2010. A total of 159 patients were recruited and randomly assigned. Data for the current analysis were collected from September 1, 2021, to March 31, 2022. All analyses were conducted with the intention-to-treat population. Closure of the diaphragmatic hiatus with crural sutures alone vs a tension-free technique using a nonabsorbable polytetrafluoroethylene mesh (Bard CruraSoft). The primary outcome was radiologically verified recurrent hiatal hernia after more than 10 years. Secondary outcomes were dysphagia scores (ranging from 1 to 4, with 1 indicating no episodes of dysphagia and 4 indicating more than 3 episodes of dysphagia per day) for solid and liquid foods, generic 36-Item Short Form Health Survey and disease-specific Gastrointestinal Symptom Rating Scale symptom assessment scores, proton pump inhibitor consumption, and reoperation rates. Intergroup comparisons of parametric data were performed using t tests; for nonparametric data, Mann-Whitney U, χ2, or Fisher exact tests were used. For intragroup comparisons vs the baseline at follow-up times, the Friedman test was used, and post hoc analysis was performed using Wilcoxon matched pairs. Of 145 available patients, follow-up data were obtained from 103 (response rate 71%; mean [SD] age at follow-up, 65 [11.3] years; 55 [53%] female), with 53 initially randomly assigned to mesh reinforcement, and 50 to crural suture alone. The mean (SD) follow-up time was 13 (1.1) years. The verified radiologic hiatal hernia recurrence rates were 11 of 29 (38%) in the mesh group vs 11 of 35 (31%) in the suture group (P = .61). However, 13 years postoperatively, mean (SD) dysphagia scores for solids remained significantly higher in the mesh group (mean [SD], 1.9 [0.7] vs 1.6 [0.9]; P = .01). Findings from this long-term follow-up of a randomized clinical trial suggest that tension-free crural repair with nonabsorbable mesh does not reduce the incidence of hiatal hernia recurrence 13 years postoperatively. This finding combined with maintained higher dysphagia scores does not support the routine use of tension-free polytetrafluoroethylene mesh closure in laparoscopic hiatal hernia repair for treatment of GERD.

Case Report: Acute Intrathoracic Sleeve Migration with Partial Volvulus after Laparoscopic Sleeve Gastrectomy and Hiatal Hernia Repair

Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric procedure in the United States and is widely accepted due to its technical ease and effectiveness. Concomitant hiatal hernia repair, if detected during an LSG, is recommended. Intrathoracic sleeve migration (ITSM), a sliding hiatal hernia that develops after LSG, is a rare complication of this procedure. This report presents an early case of ITSM due to intermittent retching, resulting in postoperative incarceration of the proximal sleeve. The patient is a 28-year-old female who underwent concomitant LSG and hiatal hernia repair and was readmitted for acute entrapment of the proximal portion of the sleeve. The patient underwent re-operation with reduction of the proximal sleeve, and omentopexy was performed for stabilization. Intraoperative esophagogastroduodenoscopy was performed to ensure the detorsion and patency of the sleeve before the surgery. No additional hiatal hernia repair was attempted. ITSM with incarceration is an interesting phenomenon that is underrecognized and underreported. It can present postoperatively with reflux symptoms and poor oral tolerance. Failure to make an accurate diagnosis and intervene can result in prolonged hospitalization and poor patient outcomes.

Magnetic sphincter augmentation as treatment of gastroesophageal reflux disease after sleeve gastrectomy.

The sleeve gastrectomy's efficacy for the reduction of excess weight- and obesity-related comorbidities has been consistently demonstrated though the improvement of postoperative reflux symptoms has been questionable. The purpose of this article is to offer a diagnostic and treatment algorithm for patients suffering from GERD after the sleeve gastrectomy. This article is comprised of recommendations of from a single expert bariatric and foregut surgeon. While previously thought to be a relative contraindication, evidence suggests that select patients with a history of sleeve gastrectomy can safely and effectively undergo magnetic sphincter augmentation (MSA) and achieve improved control of reflux and discontinuation of PPIs. Concomitant hiatal hernia repair with MSA is recommended. MSA is a fantastic strategy for managing GERD after sleeve gastrectomy with careful patient selection.

Impact of concurrent hiatal hernia repair during laparoscopic sleeve gastrectomy on patient-reported gastroesophageal reflux symptoms: astate-wide analysis.

Concurrent hiatal hernia repair (HHR) during laparoscopic sleeve gastrectomy (LSG) may improve gastroesophageal reflux disease (GERD) symptoms. However, patient-reported outcomes are limited, and the influence of surgeon technique remains unclear. To assess patient-reported GERD severity before and after LSG with and without concomitant HHR. Teaching and non-teaching hospitals participating in a state-wide quality improvement collaborative. Using a state-wide bariatric-specific data registry, all patients who underwent a primary LSG between 2015 and 2019 who completed a baseline and 1 year validated GERD health related quality of life (GERD-HRQL) survey were identified (n = 11,742). GERD severity at 1 year as well as 30-day risk-adjusted adverse events was compared between patients who underwent LSG with or without HHR. Results were also stratified by anterior versus posterior HHR. A total of 4015 patients underwent a LSG-HHR (34%). Compared to patients who underwent LSG without HHR, LSG-HHR patients were older (47.8 yr versus 44.6 yr; P < .0001), had a lower preoperative body mass index (BMI) (45.8 kg/m2 versus 48 kg/m2; P < .0001) and more likely to be female (85.2% versus 77.6%, P < .0001). Patients who underwent a posterior HHR (n = 3205) experienced higher rates of symptom improvement (69.5% versus 64.0%, P = .0014) and lower rates of new onset symptoms at 1 year (28.2% versus 30.2%, P = .0500). Patients who underwent an anterior HHR (n = 496) experienced higher rates of hemorrhage and readmissions with no significant difference in symptom improvement. Concurrent posterior hiatal HHR at the time of sleeve gastrectomy can improve reflux symptoms. Patients undergoing anterior repair derive no benefit and should be avoided.

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.

Hiatal hernia repair with transoral incisionless fundoplication versus Nissen fundoplication for gastroesophageal reflux disease: A retrospective study.

Background and study aims Concomitant hiatal hernia (HH) repair with transoral incisionless fundoplication (TIF) is a therapeutic option for patients with HH > 2 cm and gastroesophageal reflux disease (GERD). Data comparing this approach with laparoscopic Nissen fundoplication (LNF) are lacking. We performed an exploratory analysis to compare these two approaches' adverse events (AEs) and clinical outcomes. Patients and methods This was a multicenter retrospective cohort study of HH repair followed by LNF versus HH repair followed by TIF in patients with GERD and moderate HH (2-5 cm). AEs were assessed using the Clavien-Dindo classification. Symptoms (heartburn/regurgitation, bloating, and dysphagia) were compared at 6 and 12 months. Results A total of 125 patients with HH repair with TIF and 70 with HH repair with LNF were compared. There was no difference in rates of discontinuing or decreasing proton pump inhibitor use, dysphagia, esophagitis, disrupted wrap, and HH recurrence between the two groups ( P > 0.05). The length of hospital stay (1 day vs. 2 days), 30-day readmission rate (0 vs. 4.3 %), early AE rate (0 vs. 18.6 %), and early serious AE rate (0 vs. 4.3 %) favored TIF (all P < 0.05). The rate of new or worse than baseline bloating was lower in the TIF group at 6 months (13.8 % vs. 30.0 %, P = 0.009). Conclusions Concomitant HH repair with TIF is feasible and associated with lower early and serious AEs compared to LNF. Further comparative efficacy studies are warranted.

IBC-Ox26 Concomitant hiatal hernia repair during bariatric surgery: is it the reinforcement making the difference?

Abstract Background Concomitant hiatal hernia repair (HHR) in patients who undergo bariatric surgery (BS) is under debate. Aims To evaluate on long-term the safety and efficacy of posterior cruroplasty (PC), simple or reinforced with a biosynthetic, absorbable mesh, performed during BS. Primary endpoint: PC's failure, defined as symptomatic HH recurrence, nonresponding to conservative treatment and requiring revisional surgery. Methods The prospective database of 1948 patients undergoing BS in a center of excellence between 2011-2020 was searched. Intraoperative measurement of the hiatal surface area (HSA) was performed routinely. Results 268 patients undergone BS and concomitant HHR (13.7%). Simple PC (group A, 165 patients) was performed during 137 sleeve gastrectomies LSG, 5 re- sleeves and 23 gastric bypasses LGB; mean BMI 43.4 ± 5.8 kg/m2, HSA mean size 3.4 ± 2 cm2. Reinforced PC (group B) was performed in 102 cases: 64 primary LSG, 23 LGB and 15 revisions of LSG; mean BMI 44.6 ± 7.7 kg/m2, HSA mean size 6.7 ± 2 cm2. PC's failure, with intrathoracic migration (ITM) was encountered in 12 cases (7.5%) of simple vs. only 4 cases (3.9%) of reinforced PC (p=0.23); hence, a repeat, reinforced PC and LGB was performed in all cases. No mesh-related complications were registered perioperatively or after long-term follow-up (mean 61 months), minimum 12 months. Only one case of cardiac metaplasia was detected 4 years postoperatively; conversion to LGB, with reinforced redo of the PC was performed. The Cox hazard analysis showed that the use of more than four stitches for cruroplasty represents a negative factor on recurrence (HR = 8; p &amp;lt; 0.05). Conclusions Our results support the use of bioabsorbable, synthetic mesh as reinforcement of HH &amp;gt; 4 cm2 in obese patients during BS, showing excellent recurrence rate results (4%). Accurate patients’ and technique's selection, combined with PC (simple or reinforced) ensure effectiveness and safety, with a combined rate of failure (HH recurrence) at 4 years of 6.0%.

The Effect of Laparoscopic Sleeve Gastrectomy With Concomitant Hiatal Hernia Repair on Gastroesophageal Reflux Disease.

The aim of this study is to reveal incidence of gastroesophageal reflux disease (GERD) after laparoscopic sleeve gastrectomy (LSG) and to determine the effect of LSG with hiatal hernia repair on GERD. A total of 440 patients, 395 of them underwent primary LSG (group A) and 45 of them underwent LSG with concomitant hiatal hernia repair (group B) between March 2018 and September 2020 were included in the study. Presence of hiatal hernia was evaluated with endoscopy and confirmed intraoperatively. Patients were evaluated for GERD symptoms in the pre and postoperative period. Two groups' data were compared. Mean age of the 440 patients was 38.4±11 years (56% female) and mean body mass index was 44.2±7 kg/m 2 . Symptomatic GERD was detected in 103 (23.4%) and hiatal hernia was detected in 45 (10.2%) patients. İn the preoperative assessment there was no difference with regard to demographics and symptomatic GERD between the 2 groups. Mean duration of follow-up was 17±5.7 (12 to 28) months in the overall study population. Mean body mass index decreased to 28.3±4.9 kg/m 2 at 12 months after LSG. Excess weight loss ratio was found to be 81±20.4%. The rate of symptomatic GERD after LSG in group A was found to be 20% (n=79/395). Of these patients, 46 (11.6%) had de novo GERD and 33 (38%) had persistent GERD. GERD resolved completely in 54 (62%) patients. In the group B, the rate of symptomatic GERD was detected as 33% (n=15/45) ( P =0.04). The rate of de novo GERD (20%) was also higher in group B ( P =0.03). The rate of persistent GERD (37%) and GERD resolution (62%) were similar in both groups. İn our study, symptomatic and de novo GERD rates were detected to be higher in the LSG+HH group than LSG alone.

Efficiency of Cruroplasty as a Treatment of Gastro-Esophageal Reflux Disease in Morbid Obese Patients with Hiatus Hernia during SleeveGastrectomy

Abstract Background The effect of laparoscopic sleeve gastrectomy (LSG) on gastroesophageal reflux disease (GERD) is controversial. Although concomitant hiatal hernia repair (HHR) at the time of LSG is common and advocated by many, there are few data on the outcomes of GERD symptoms in these patients. The aim of this study was to evaluate the effect of concomitant HHR on GERD symptoms in morbidly obese patients undergoing LSG. Aim of the Work To analyse the impact of hiatal hernia repair (HHR) on gastro-oesophageal reflux disease (GERD) in morbidly obese patients with hiatus hernia undergoing laparoscopic sleeve gastrectomy (LSG). Patients and Methods This is a retrospective cohart study. We collected the data of Patients who underwent lap sleeve gastrectomy with cruroplsty in the same operation in the period between July 2018 and July 2019. Results Before surgery, symptomatic GERD was present in 14 patients (70%), and HH was diagnosed In 20 patients (100%), HH was diagnosed pre-operatively. The mean follow-up was 6 months. GERD remission occurred in 18 patients (90%). In the remaining 2 patients, antireflux medications were diminished, with complete control of symptoms. HH recurrences developed in 1 patient (10%). "De novo" GERD symptoms developed in 22.9% of the patients undergoing SG alone compared with 0% of patients undergoing SG plus HHR. Conclusion SG with HHR is feasible and safe, providing good management of GERD in obese patients with reflux symptoms. Small hiatal defects could be underdiagnosed at preoperative endoscopy and/or upper gastrointestinal contrast study. Thus, a careful examination of the crura is always recommended intraoperatively.

Response of Laryngopharyngeal Symptoms to Transoral Incisionless Fundoplication in Patients with Refractory Proven Gastroesophageal Reflux.

Patients with laryngopharyngeal reflux (LPR) symptoms may not respond to proton pump inhibitors (PPI) if they have an alternative laryngeal diagnosis or high-volume reflux. Transoral incisionless fundoplication (TIF) or TIF with concomitant hiatal hernia repair (cTIF) are effective in decreasing symptoms of gastroesophageal reflux disease (GERD) but are not well studied in patients with LPR symptoms. This prospective multicenter study assessed the patient-reported and clinical outcomes after TIF/cTIF in patients with LPR symptoms and proven GERD. Patients with refractory LPR symptoms (reflux symptom index [RSI] > 13) and with erosive esophagitis, Barrett's esophagus, and/or pathologic acid reflux by distal esophageal pH testing were evaluated before and after a minimum of 6 months after TIF/cTIF. The primary outcome was normalization of RSI. Secondary outcomes were >50% improvement in GERD-Health-Related Quality of Life (GERD-HRQL), normalization of esophageal acid exposure time, discontinuation of PPI, and patient satisfaction. Forty-nine patients had TIF (n = 26) or cTIF (n = 23) with at least 6 months follow-up. Mean pre- and post TIF/cTIF RSI were 23.6 and 5.9 (mean difference: 17.7, P < .001). Post TIF/cTIF, 90% of patients had improved GERD-HQRL score, 85% normalized RSI, 75% normalized esophageal acid exposure time, and 80% discontinued PPI. No serious procedure-related adverse events occurred. Patient satisfaction was 4% prior to TIF/cTIF and 73% after TIF/cTIF (P < .001). In patients with objective evidence of GERD, TIF, or cTIF are safe and effective in controlling LPR symptoms as measured by normalization of RSI and improvement in patient satisfaction after TIF/cTIF. Level 4.

Effect of Concomitant Laparoscopic Sleeve Gastrectomy and Hiatal Hernia Repair on Gastroesophageal Reflux Disease in Patients with Obesity: a Systematic Review and Meta-analysis

Hiatal hernia repair (HHR) during sleeve gastrectomy (SG) is recommended when hiatal hernia (HH) is found intraoperatively. However, its effect on gastroesophageal reflux disease (GERD) remains controversial. To evaluate the effect of concomitant SG and HHR on GERD in patients with obesity. Web of Science, PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov databases were searched for all studies reporting the efficacy of SG+HHR for patients with obesity and GERD up to March 2021. A total of 18 studies totaling 937 patients met the inclusion criteria. The results of meta-analysis showed that after SG+HHR, there was a significant reduction in GERD symptoms (OR: 0.20; 95% CI: 0.10 to 0.41; P < 0.00001), improvement in esophagitis (OR: 0.12, 95% CI: 0.05 to 0.26, P < 0.001), and decrease in GERD-HRQL (MD: 19.13, 95% CI: -3.74 to 34.51; P=0.01). The incidence of GERD remission after SG+HHR was 68.0% (95% CI: 55.0-80.9%), de novo GERD was 12% (95% CI: 8-16%), and HH recurrence was 11% (95% CI: 4 to 19%). SG+HHR was superior to SG alone in GERD remission (OR: 2.97, 95% CI: 1.78 to 4.95, P < 0.0001). However, there was no significant difference in de novo GERD after SG+HHR compared with SG alone. SG+HHR can positively affect weight loss, GERD resolution, esophagitis reduction, and GERD-HRQL improvement. SG+HHR seems to have a promising future in patients with obesity and GERD. However, further studies based on objective assessment are warranted to evaluate these results better.

Impact of the Hepatic Branch of the Vagus Nerve Transection in Laparoscopic Sleeve Gastrectomy for Patients with Obesity and Type 2 Diabetes Mellitus.

An increase in gastroesophageal reflux disease (GERD) after laparoscopic sleeve gastrectomy (LSG) has been reported, and concomitant hiatal hernia repair (HHR) during LSG is expected to reduce the incidence of post-LSG GERD. In HHR, the hepatic branch of the vagus nerve is anatomically transected. Recent experimental animal models suggest that vagotomy may affect glycemic control and weight loss through a neuroendocrine response. To examine whether LSG with/without hepatic branch vagotomy (HV) has a clinical impact on glycemic control in patients with obesity and type 2 diabetes mellitus (T2DM). Furthermore, the impact on weight loss and post-LSG GERD were evaluated. A total of 204 Japanese patients with obesity and T2DM, who underwent LSG and completed 1-year follow-up, were retrospectively analyzed. Operative outcomes, weight loss, glycemic, and GERD-related parameters were compared between the LSG/HHR/HV group (n = 89) and the LSG group (n = 115). There was no significant difference in the background factors in terms of anthropometric and T2DM-related parameters between the groups. The median operation times in the LSG/HHR/HV and LSG groups were 133 and 124 minutes, respectively (p = 0.236). At 1 year, the diabetes remission rate, HbA1c, fasting glucose, and C-peptide levels were all comparable between the groups. The weight loss effect was also comparable. The patients in the LSG/HHR/HV group achieved significant improvement and prevention of GERD and hiatus hernia (p < 0.001). HV does not appear to have a clinical impact on glycemic control and weight loss. Concomitant HHR with LSG serves to reduce post-LSG GERD.

Outcomes of Bariatric Surgery With Concomitant Hiatal Hernia Repair Using an Absorbable Tissue Matrix.

Hiatal hernias are a common finding in patients who undergo bariatric surgery with an incidence of about 20% of all bariatric patients. Controversy exists on the utility of a biosynthetic tissue matrix (BTM) usage in combination with crural repair. This study was designed to explore the safety and benefits of the use of a BTM during concomitant hiatal hernia repair with bariatric surgical procedures. This was a retrospective chart review of bariatric surgical patients who underwent a concomitant hiatal hernia repair at a single practice at a tertiary academic medical center from January 2014 to February 2019. A total of 420 patients were reviewed. Hiatal BTM reinforcement, recurrence, and postoperative proton pump inhibitor use were reported by type of operation. Recurrence was higher in gastric bypass patients who underwent hiatal hernia repair with suture cruroplasty alone vs. those who also underwent hiatal BTM reinforcement (7.1% vs. 3.7%, P = .52) and significantly higher in gastric sleeve patients who underwent hiatal hernia repair with suture cruroplasty alone vs. those who also underwent hiatal BTM reinforcement (7.1% vs. .5%, P = .01). No patient required reoperation for hiatal hernia recurrence. Performing Roux-en-Y gastric bypass or vertical sleeve gastrectomy with concomitant hiatal hernia repair is safe and durable. Employing crural reinforcement with BTM may be of benefit in reducing recurrence rates of hiatal hernia, particularly in sleeve gastrectomy patients.
