801. ROBOTIC ASSISTED LAPAROSCOPIC GIANT PARA-OESOPHAGEAL HERNIA REPAIR: 5-YEAR EXPERIENCE

Abstract Background Prior to laparoscopic era, giant paraesophageal hernia repair (GPEHR) was considered a relatively morbid operation requiring thoracotomy or laparotomy or both. GPEHR has been shown to be amenable to laparoscopic approach with low morbidity and mortality. We presented the outcome of over 200 cases of laparoscopic GPEHR (LGPEHR) with long-term follow- up over 20 years at DDW 2022. We have been performing robotic-assisted laparoscopic giant paraesophageal hernia repair (RAL-GPEHR) since 2018 and present our results. Methods We did a retrospective analysis of prospectively collected data of RAL- GPEHR using the DaVinci Xi between December 2018 and March 2024. All operating data are electronically recorded automatically by DaVinci Xi system for each surgeon/console user. Demographic data, clinical presentation, pre-operative assessment, and testing including haemoglobin (Hb), respiratory function {Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 Second (FEV1)} as well as quality-of-life (QoL) with SF-36 questioners (including general health, physical, emotional, and social components), length of hospital stay (LOS), morbidity, mortality and follow up outcomes (Clinical, Hb, radiological, respiratory and QoL) were recorded. Results Twenty patients underwent RAL-GPEHR with 15(75%) having crural repair plus gastropexy and 5(25%) patients having additional Toupet fundoplication. Fourteen (70%) were females. Data is presented in Table 1. Presenting symptoms were dyspnoea, reflux, post-prandial pain, and dysphagia with 7(35%) anaemic. Eight (40%) were ASA III and 12(60%) ASA II. Thirteen (65%) were Type III-GPEH, 4(20%)-Type IV, one-Type II (5%) and 2(10%) recurrent GPEH. Blood loss was minimal with no intra-operative complications or conversions to open. One (5%) had post-operative chest infection. Symptoms improved in all post-operatively with improvement of Hb, FVC, FEV1 and QoL. Radiological recurrence occurred in one (5%) but remains asymptomatic. Conclusions This report represents our initial experience of a small number of patients undergoing RAL-GPEHR which has proved to be feasible and safe. A long-term follow- up with a large series of patients is required to compare long-term outcomes especially symptomatic recurrences and QoL.

OGBN O07 Factors in recurrence following 862 giant paraesophageal hernia repairs

Abstract Background Repair of giant paraesophageal hernia (PEH) is associated with a considerable hernia recurrence rate by objective measures. This study evaluated trends in outcomes of laparoscopic non-mesh repair of giant PEH over 30 years, and factors associated with anatomical recurrence. Methods Data was extracted from a single-surgeon prospective database of laparoscopic repair of giant PEH from 1991-2021. Upper endoscopy was performed within 12 months postoperatively and selectively thereafter. Any supra-diaphragmatic stomach was defined as anatomical recurrence. Cases were chronologically divided into tertiles with trends in casemix, operative factors and outcomes evaluated. Patient and hernia characteristics, and technical operative factors, including “composite repair” (360-degree fundoplication with esophagopexy and cardiopexy to right crus), were evaluated with univariate and multivariate analysis. Results 862 repairs met selection criteria. Mean age 69.3years, majority(65.8%) female and hernia type III(87.4%) with median hernia size 66%. There was an increasing proportion of “composite repair” after the first decade(Group1, 2.7%;Group2, 81.9%;Group3, 100%;p<0.001).There were less anatomical hernia recurrence(Group1, 36.6%;Group2, 22.9%;Group3, 22.7%;p<0.001) over time. The overall anatomical recurrence rate was 27.3% with median followup 33months(IQR 16, 68). There were 10(1.2%) Clavien-Dindo grade ≥III complications including two perioperative deaths(0.2%). Multivariate analysis identified age<70years, presence of Barrett’s, absence of “composite repair”, and hiatus closure under tension as independent factors associated with recurrence(HR1.27,95%CI0.88-1.82,p=0.01;HR1.58,95%CI1.12-2.23,p=0.009;HR1.72,95%CI1.2-2.44,p=0.002;HR2.05,95%CI1.33-3.17,p=0.001,respectively). Conclusions Hernia recurrence rates decreased with increasing case volume. This coincided with the increasing adoption of “composite repair”, supporting the possible improvement in recurrence rates with this approach. Repair was associated with substantial anatomical recurrence associated with patient and technique factors. Patient factors included age <70 years, Barrett’s esophagus, and hiatus tension. “Composite repair” was associated with lower recurrence rate.

Recurrence in Paraesophageal Hernia: Patient Factors and Composite Surgical Repair in 862 Cases

BackgroundRepair of giant paraesophageal hernia (PEH) is associated with a considerable hernia recurrence rate by objective measures. This study analyzed a large series of laparoscopic giant PEH repair to determine factors associated with anatomical recurrence. MethodData was extracted from a single-surgeon prospective database of laparoscopic repair of giant PEH from 1991 to 2021. Upper endoscopy was performed within 12 months postoperatively and selectively thereafter. Any supra-diaphragmatic stomach was defined as anatomical recurrence. Patient and hernia characteristics and technical operative factors, including “composite repair” (360° fundoplication with esophagopexy and cardiopexy to right crus), were evaluated with univariate and multivariate analysis. ResultsLaparoscopic primary repair was performed in 862 patients. The anatomical recurrence rate was 27.3% with median follow-up of 33 months (IQR 16, 68). Recurrence was symptomatic in 45% of cases and 29% of these underwent a revision operation. Hernia recurrence was associated with younger age, adversely affected quality of life, and were associated with non-composite repair. Multivariate analysis identified age < 70 years, presence of Barrett’s esophagus, absence of “composite repair”, and hiatus closure under tension as independent factors associated with recurrence (HR 1.27, 95%CI 0.88–1.82, p = 0.01; HR 1.58, 95%CI 1.12–2.23, p = 0.009; HR 1.72, 95%CI 1.2–2.44, p = 0.002; HR 2.05, 95%CI 1.33–3.17, p = 0.001, respectively). ConclusionRepair of giant PEH is associated with substantial anatomical recurrence associated with patient and technique factors. Patient factors included age < 70 years, Barrett’s esophagus, and hiatus tension. “Composite repair” was associated with lower recurrence rate.

The impact of frailty on outcomes following laparoscopic repair of 'giant' paraesophageal hernias.

Frailty is a measure of physiologic reserve and correlates with surgical outcomes in the elderly. Patients who present with giant paraesophageal hernias (PEH) are typically older than 65. We defined 'giant' as a PEH with 50% or more of the stomach in the chest. We hypothesized that frailty correlates with 30-day complications, length of stay, and discharge destination following laparoscopic giant PEH repair. Patients older than 65 to undergo primary laparoscopic repair of a giant PEH at a single academic medical center between 2015 and 2022 were included. Hernia size was determined by preoperative imaging. Frailty was assessed clinically prior to surgery using the modified Frailty Index (mFI), an 11-item instrument that counts clinical deficits associated with frailty. A score ≥ 3 was considered frail. A major complication was a Clavien grade IIIB or higher. Of the 162 patients included in the study, mean age was 74.4 ± 7.2, and 66% of patients were female (n = 128). The mFI was ≥ 3 in 37 patients (22.8%). Frail patients were older (78 ± 7.9 vs. 73 ± 6.6years, p = 0.02). There was no difference in overall complication rate (40.5% vs. 29.6%, p = 0.22) or major complication rate (8.1% vs. 4.8%, p = 0.20) between frail and non-frail patients. Functionally impaired patients (METS < 4) were more likely to develop a major complication (17.9% vs. 3.0%, p < 0.01). Average length of stay was 2.4days, and frail patients experienced a longer mean hospital stay (2.5 ± 0.2 vs. 2.3 ± 1.8, p = 0.03). Frail patients were more likely to be discharged to a destination other than home. Increased frailty as assessed by the mFI is correlated with length of stay and discharge destination following laparoscopic repair of giant PEH in patients > 65. Complication rates were comparable for both frail and non-frail cohorts.

Health-related quality of life after laparoscopic repair of giant paraesophageal hernia: how does recurrence in CT scan compare to clinical success?

BackgroundComputed tomography (CT) is widely used in the diagnosis of giant paraesophageal hernias (GPEH) but has not been utilised systematically for follow-up. We performed a cross-sectional observational study to assess mid-term outcomes of elective laparoscopic GPEH repair. The primary objective of the study was to evaluate the radiological hernia recurrence rate by CT and to determine its association with current symptoms and quality of life.MethodsAll non-emergent laparoscopic GPEH repairs between 2010 to 2015 were identified from hospital medical records. Each patient was offered non-contrast CT and sent questionnaires for disease-specific symptoms and health-related quality of life.ResultsThe inclusion criteria were met by 165 patients (74% female, mean age 67 years). Total recurrence rate was 29.3%. Major recurrent hernia (> 5 cm) was revealed by CT in 4 patients (4.3%). Radiological findings did not correlate with symptom-related quality of life. Perioperative mortality occurred in 1 patient (0.6%). Complications were reported in 27 patients (16.4%).ConclusionsSuccessful laparoscopic repair of GPEH requires both expertise and experience. It appears to lead to effective symptom relief with high patient satisfaction. However, small radiological recurrences are common but do not affect postoperative symptom-related patient wellbeing.

Laparoscopic repair of giant paraesophageal hernia: are there factors associated with anatomic recurrence?

Repair of giant paraesophageal hernia (PEH) is associated with a favorably high rate of symptom improvement; however, rates of recurrence by objective measures remain high. Herein we analyze our experience with laparoscopic giant PEH repair to determine what factors if any can predict anatomic recurrence. We prospectively collected data on PEH characteristics, variations in operative techniques, and surgeon factors for 595 patients undergoing laparoscopic PEH repair from 2008 to 2015. Upper GI study was performed at 6months postoperatively and selectively thereafter-any supra-diaphragmatic stomach was considered hiatal hernia recurrence. Exclusion criteria included revisional operation (22.4%), size <5cm (17.6%), inadequate follow-up (17.8%), and confounding concurrent operations (6.9%). Inclusion criteria were met by 202 patients (31% male, median age 71years, and median BMI 28.7). At a median follow-up of 6months (IQR 6-12), overall anatomic recurrence rate was 34.2%. Symptom recurrence rate was 9.9% and revisional operation was required in ten patients (4.9%). Neither patient demographics nor PEH characteristics (size, presence of Cameron erosions, esophagitis, or Barrett's) correlated with anatomic recurrence. Technical factors at operation (mobilized intra-abdominal length of esophagus, Collis gastroplasty, number of anterior/posterior stitches, use of crural buttress, use of pledgeted or mattress sutures, or gastrostomy) were also not correlated with recurrence. Regarding surgeon factors, annual volume of fewer than ten cases per year was associated with increased risk of anatomic failure (54 vs 33%, P=0.02). Multivariate analysis identified surgeon experience (<10 cases per year) as an independent factor associated with early hiatal hernia recurrence (OR 3.7, 95% CI 1.34-10.9). Laparoscopic repair of giant PEH is associated with high anatomic recurrence rate but excellent symptom control. PEH characteristics and technical operative variables do not appear to significantly affect rates of recurrence. In contrast, surgeon volume does appear to contribute significantly to durability of repair.

Combining laparoscopic giant paraesophageal hernia repair with sleeve gastrectomy in obese patients.

Surgical treatment for giant paraesophageal hernias (PEH) in morbidly obese patients (BMI > 35) continues to be a difficult problem. Prior studies have demonstrated recurrence rates of up to 40% with higher rates in morbidly obese patients. Reports have shown success combining repair with a bariatric procedure to decrease recurrence rates while achieving weight loss. We report mid-term results from a larger series with combining laparoscopic giant PEH repair with sleeve gastrectomy (SG). We reviewed all combined cases of PEH repairs with SG done at a single institution from 2008 to 2013. The surgical technique was standardized and absorbable bio-prosthetic buttress crural closure reinforcement was used selectively. Yearly upper gastrointestinal radiographic (UGI) studies and postoperative Gastroesophageal Reflux Disease Health-Related Quality of Life questionnaires were completed. 33 patients were enrolled; 18 patients (55%) completed the study No 30-day morbidity or mortality occurred. 16 patients were female; the average age was 55.3 ± 11.4 years (30-72) with follow-up from surgery of 19.9 ± 16.7 months (6-66). The average weight loss was 23.5 ± 12.7 kg (8-57); excess body weight loss was 46 ± 25.8% (18-112). Based on the UGIs, 9/18 (50%) had no evidence of hernia recurrence, while 6/18 (33%) demonstrated a small (<2 cm) recurrence. 3/18 (17%) patients had evidence of moderate recurrence (3-5 cm). Postoperative GERD-HRQL scores revealed an average score of 10 ± 7 (2-26). All patients reported being "satisfied" with their operation and weight loss and also had a significant improvement in foregut symptoms. No patient has required surgical revision and residual symptoms responded to conservative management. PEH in morbidly obese patients remain a complex surgical problem. Our case series shows that combination with SG may decrease recurrence rates but more importantly leads to lower rates of reoperation for symptomatic recurrence. Patients also garner the added medical benefits of weight loss.

A clinical prediction rule for perioperative mortality and major morbidity after laparoscopic giant paraesophageal hernia repair

In the current era, giant paraesophageal hernia repair by experienced minimally invasive surgeons has excellent perioperative outcomes when performed electively. However, nonelective repair is associated with significantly greater morbidity and mortality, even when performed laparoscopically. We hypothesized that clinical prediction tools using pretreatment variables could be developed that would predict patient-specific risk of postoperative morbidity and mortality. We assessed 980 patients who underwent giant paraesophageal hernia repair (1997-2010; 80% elective and 97% laparoscopic). We assessed the association between clinical predictor covariates, including demographics, comorbidity, and urgency of operation, and risk for in-hospital or 30-day mortality and major morbidity. By using forward stepwise logistic regression, clinical prediction models for mortality and major morbidity were developed. Urgency of operation was a significant predictor of mortality (elective 1.1% [9/778] vs nonelective 8% [16/199]; P < .001) and major morbidity (elective 18% [143/781] vs nonelective 41% [81/199]; P < .001). The most common adverse outcomes were pulmonary complications (n = 199; 20%). A 4-covariate prediction model consisting of age 80 years or more, urgency of operation, and 2 Charlson comorbidity index variables (congestive heart failure and pulmonary disease) provided discriminatory accuracy for postoperative mortality of 88%. A 5-covariate model (sex, age by decade, urgency of operation, congestive heart failure, and pulmonary disease) for major postoperative morbidity was 68% predictive. Predictive models using pretreatment patient characteristics can accurately predict mortality and major morbidity after giant paraesophageal hernia repair. After prospective validation, these models could provide patient-specific risk prediction, tailored for individual patient characteristics, and contribute to decision-making regarding surgical intervention.

Outcomes after a decade of laparoscopic giant paraesophageal hernia repair

Laparoscopic repair of giant paraesophageal hernia is a complex operation requiring significant laparoscopic expertise. Our objective was to compare our current approach and outcomes for laparoscopic repair of giant paraesophageal hernia with our previous experience. A retrospective review of patients undergoing nonemergency laparoscopic repair of giant paraesophageal hernia, stratified by early versus current era (January 1997-June 2003 and July 2003-June 2008), was performed. We evaluated clinical outcomes, barium esophagogram, and quality of life. Laparoscopic repair of giant paraesophageal hernia was performed in 662 patients (median age 70 years, range 19-92 years) with a median percentage of herniated stomach of 70% (range 30%-100%). With time, use of Collis gastroplasty decreased (86% to 53%), as did crural mesh reinforcement (17% to 12%). Current era patients were 50% more likely to have a Charlson comorbidity index score greater than 3. Thirty-day mortality was 1.7% (11/662). Mortality and complication rates were stable with time, despite increasing comorbid disease in current era. Postoperative gastroesophageal reflux disease health-related quality of life scores were available for 489 patients (30-month median follow-up), with good to excellent results in 90% (438/489). Radiographic recurrence (15.7%) was not associated with symptom recurrence. Reoperation occurred in 3.2% (21/662). With time, we have obtained significant minimally invasive experience and refined our approach to laparoscopic repair of giant paraesophageal hernia. Perioperative morbidity and mortality remain low, despite increased comorbid disease in the current era. Laparoscopic repair provided excellent patient satisfaction and symptom improvement, even with small radiographic recurrences. Reoperation rates were comparable to the best open series.

1019 Perioperative Treatment with Infliximab (IFX) in Patients with Crohn's (CD) and Ulcerative Colitis (UC) Is Not Associated with Increased Rate of Postoperative Complications

Background: Laparoscopic repair of giant paraesophageal hernias (LRGPEH) is increasingly utilized with excellent short-term results. Long-term (>60 months) clinical and radiographic results, however, are poorly described. Our objective was to evaluate the long term results after minimally invasive repair of GPEH. Methods: We performed a review of patients undergoing elective LRGPEH (1995 to 2002) who had a minimum of 60-month clinical or radiographic follow-up. Clinical outcomes, barium swallow and quality-of-life measures were reviewed. Results: There were 256 patients who underwent LRGPEH in this time-period. A minimum of 60-month clinical or radiographic follow-up was available on 105 patients. Hernia reduction, sac excision, crural repair (13.7%mesh-reinforcement) and fundoplication were performed in 98%. A Collis-gastroplasty was performed in 89 patients (85%). Median time for clinical follow-up was 82 months (60-124). GERD-Health-Related-Quality-of-Life (GERD-HRQL) scores were available for 98 patients, with a mean 3.9 ±6 (median 1, range 0-23; 0=no symptoms-45= worst). Occasional heartburn and dysphagia to solids were the most common persistent symptoms in 30% of patients. According to the GERD-HRQL scale (excellent=0-5; good=6-10; fair=11-15; poor=16-45), the results were excellent to good in 86.8% of patients, confirming themild nature of the symptoms. Barium-swallowwas obtained in 79/105 (75%) at a median time of 80 months (60-126). Radiographic recurrence of a hiatal hernia was identified in 9 (11%). GERD-HRQL scores were excellent in 77% of patients with radiographic recurrence compared to 72% in patients without radiographic recurrence. When patients were queried regarding satisfaction with surgery, over 90% (83/90) were satisfied or very satisfied. Re-operation was required in 5 (4.7%) patients for symptomatic recurrence at a median 44 months post-operative (range 8-80). Conclusions: This report summarizes the long-term results (7 years) of LRGPEH in 105 patients. Reoperation was required for symptomatic recurrence in only 4.7%. The GERD-related quality of life was well preserved and 90% of patients were satisfied with their surgery.

Laparoscopic repair of giant paraesophageal hernia: 100 consecutive cases.

To summarize the authors' laparoscopic experience for paraesophageal hernia (PEH). Laparoscopic antireflux surgery and repair of small hiatal hernias are now routinely performed. Repair of a giant PEH is more complex and requires conventional surgery in most centers. Giant PEH accounts for approximately 5% of all hiatal hernias. Medical management may be associated with a 50% progression of symptoms and a significant death rate. Conventional open surgery has a low death rate, but complications are significant and return to routine activities is delayed in this frequently elderly population. Recently, short-term outcome studies have reported that minimally invasive approaches to PEH may be associated with a lower complication rate, a shorter hospital stay, and faster recovery. From July 1995 to February 2000, 100 patients (median age 68) underwent laparoscopic repair of a giant PEH. Follow-up included heartburn scores and quality of life measurements using the SF-12 physical component and mental component summary scores. There were 8 type II hernias, 85 type III, and 7 type IV. Sac removal, crural repair, and antireflux procedures were performed (72 Nissen, 27 Collis-Nissen). The 30-day death rate was zero; there was one surgery-related death at 5 months from a perioperative stroke. Intraoperative complications included pneumothorax, esophageal perforation, and gastric perforation. There were three conversions to open surgery. Major postoperative complications included stroke, myocardial infarction, pulmonary emboli, adult respiratory distress syndrome, and repeat operations (two for abscess and one each for hematoma, repair leak, and recurrent hernia). Median length of stay was 2 days. Median follow-up at 12 months revealed resumption of proton pump inhibitors in 10 patients and one repeat operation for recurrence. The mean heartburn score was 2.3 (0, best; 45, worst); the satisfaction score was 91%; physical and mental component summary scores were 49 and 54, respectively (normal, 50). This report represents the largest series to date of laparoscopic repair of giant PEH. In the authors' center with extensive experience in minimally invasive surgery, laparoscopic repair of giant PEH was successfully performed in 97% of patients, with a minimal complication rate, a 2-day length of stay, and good intermediate results.

Esophageal motility and outcomes following laparoscopic paraesophageal hernia repair and fundoplication

Background: The addition of an antireflux procedure to all giant paraesophageal hernia (PEH) repairs remains controversial. In addition there are no series evaluating the impact of hernia repair and fundoplication on esophageal physiology. This study examines the outcomes of PEH repair with fundoplication and examines the results of preoperative and postoperative motility and pH testing. Methods: An analysis of a data base containing all patients undergoing PEH repair between September 1994 and December 1997. Patients underwent laparoscopic sac reduction, hernia repair, and fundoplication. Follow-up was performed under protocol and consisted of a symptoms assessment form, 24 hour pH, and manometry. Results: Fifty-two patients (mean age 63) were treated: 59% complained of heartburn, 50% dysphagia, and 27% chest pain; 26% had a body motility disorder. Complete manometry was not possible in 41%. Mean operative time was 4 hours. There were 48 Nissen, 4 Toupet, and 7 Collis-Nissen procedures. There were 3 (6%) intraoperative and 3 (6%) postoperative complications. There were no operative mortalities. Hospital stay was 3 days (1 to 29). Late follow-up (18 months) was available for 96% of patients and showed dysphagia in 6%, heartburn in 10%, and recurrent herniation in 8%. Objective postoperative testing was available in 61% of the patients at a mean of 8 months. Twenty-four hour pH tests were abnormal in 4 patients (2 asymptomatic and 2 with a Collis). Lower esophageal sphincter pressures increased 63% and functioned well in 71% of patients; 50% of preoperative motility disorders improved following repair. Conclusions: Laparoscopic repair of giant PEH is technically difficult but feasible. Routine addition of a fundoplication is advised, as preoperative testing is unreliable for a selective approach and fundoplications are well tolerated in this group of patients.
