BN SO34 - Outcomes in giant versus non-giant hiatus hernia repair: Same payment different operative burden

Abstract Background Hospital trust payment for operative procedures often rely on coding systems like the NHS's Office of Population Censuses and Surveys (OPCS) codes, which determine reimbursement rates. Both giant hiatus hernia (GHH) and non-giant hiatus hernia (NGHH) repairs often share the same code, as in our trust. This results in equal reimbursement to trusts for procedures with higher operative burden and resource needs. This study aims to assess differences in the patient population, their hiatal type, operative challenges and post-operative outcomes between GHH and NGHH repairs. Method All patients undergoing primary hiatus hernia surgery between March 2019 to March 2024 at a single institution were included. Retrospective review of electronic records were utilised to record: patient demographics, hernia type, operative details, length of stay (LOS), post-operative course and need for a return to theatre (RTT). Outcomes were comparison of surgical approach, use of mesh and gastropexy (as proxy measures to indicate difficulty of operation), 30-day morbidity measured using Clavien-Dindo (CD) grading and 30-day mortality and RTT. Analysis was undertaken using un-paired t-test and Chi2. A p-value of <0.05 was considered statistically significant. Results Table 1.

GHH repairs have an increased likelihood of undergoing open procedures, use of mesh, and gastropexy, reflecting their greater complexity. GHH patients are older, have higher ASA grades, and present with more advanced hernia types compared to NGHH patients. Additionally, GHH repairs result in longer hospital stays. The findings underscore the need for improved coding accuracy to reflect these disparities accurately in patient demographics, operative strategies, and recovery outcomes within hospital trusts, ensuring appropriate resource allocation and reimbursement based on procedural complexity.

BN SO32 - Operative techniques and outcomes following giant hiatus hernia repair: 5 years of tertiary centre experience

Abstract Background Giant hiatus hernia (GHH) repair is a complex surgical challenge, often requiring advanced techniques and specialised expertise. Whilst the repair of small hiatus hernias is well-documented, the optimal strategy for giant hernias remains debated. This study reviews five years of experience at a tertiary centre, focusing on operative techniques and outcomes. The aim is to identify trends and best practices that enhance patient outcomes and minimise complications in the repair of GHH. Method All patients undergoing primary GHH surgery between March 2019 and March 2024 at a tertiary institution and a five surgeon upper GI service. Retrospective review of electronic records were utilised to document patient demographics, type of hernia, operative details including surgical approach (open/laparoscopic/robotic), use of fundoplication, use of mesh and gastropexy. Outcomes measured included 30-day morbidity (Clavien-Dindo (CD) grading), 30-day mortality, binary symptom recurrence, length of stay (LOS), need for return to theatre (RTT) and RTT versus mesh use. Analysis undertaken using paired t-test. Statistical significance was set as p<0.05. Results 91 patients underwent GHH repair with median age 70 (31-93) years, 66.7% female, average BMI 30.8(±5.4). ASA: ≤2 (72.4%), 3 (25.5%), 4 (2.1%). Hernia types: 2 (15.7%), 3 (55.4%), 4 (28.9%). Approach: open 6.6%, laparoscopic 61.5%, robotic 31.9%. Fundoplication in 88%, gastropexy in 13%, 2 cases utilised both. Mesh: 91.2% without, 8.8% biologic, nil prosthetic. Median LOS 2 days (0-161). Median follow-up 8 weeks (1-172). Symptoms recurred in 25.6%. 94.5% had no significant complications (CD≤2). 5.5% had RTT≤30 days. 4.4% RTT>30 days. No mortalities. No significant difference in RTT and mesh use (p=0.7832). Conclusion This five-year review confirms that GHH repair using open, laparoscopic, and robotic techniques is effective and safe, even in an older population with high ASA scores. The study highlights minimal complications (94.5% with CD≤2). Only 4.8% required a RTT within 30 days. RTT was not significantly impacted by the use of mesh however this may represent a type two error given the limited use of mesh and low number of patients that RTT. These findings support the tailored use of advanced surgical techniques, mesh, and gastropexy as effective strategies for managing GHH in a tertiary care setting.

EGS SO13 - Evaluation of Different Surgical Risk Prediction Models in Predicting Morbidity and Mortality in Giant Hiatus and Diaphragmatic Hernia Repairs

Abstract Background Emergency giant hiatus hernia and diaphragmatic hernia repairs are associated with high rates of mortality and morbidity; different studies reported variable outcomes. Accurate risk assessment empowers patients to provide informed consent and also serves as a valuable tool for identifying individuals who may require enhanced postoperative care, such as respiratory support and critical care admission. Various risk prediction tools have been developed to assist clinicians in making decisions to aid in stratifying the risk of surgical management. We aimed to assess the effectiveness of different risk prediction models in predicting mortality and morbidity in this patient cohort. Method Retrospective analysis performed on cases between May, 2010 and January, 2021 in a tertiary adult upper gastro-intestinal centre. The outcomes from the operations were assessed and compared with the predicted morbidity and mortality for different risk prediction models. Including the Surgical Outcome Risk Tool (SORT), the National Emergency Laparotomy Audit (NELA), parsimonious NELA and the American College of Surgeons National Surgical Quality Improvement Programme (ACS-NSQIP). The models were compared using the area under the curve (AUC). Morbidity models included Portsmouth Physiological and Operative Severity Score (P-POSSUM) and the ACS-NSQIP. Morbidity was evaluated by calculating the comprehensive complication index (CCI). Results A total of 108 patients met the criteria and were included in the analysis. Among these 50.9% were females. The median age was 69 (IQR 59-78). The 30-day mortality rate was 6.93% (7 patients), six patients died during the same admission, and one patient died during a re-admission. ACS-NQSIP had the highest predictive power for mortality (AUC = 0.6344), in comparison to NELA (AUC=0.5665), parsimonious NELA (AUC=0.4866) and SORT (AUC = 0.4342). Both ACS-NSQIP and P-POSSUM showed moderate correlation to CCI (rho = 0.489, p<0.001 and 0.446, p<0.001 respectively). Conclusion ACS-NSQIP is a better predictor of both mortality and morbidity in emergency giant hiatus and diaphragmatic hernia repairs when compared to NELA, parsimonious NELA, P-POSSUM and SORT. Interestingly, parsimonious NELA had a lower prediction rate when compared with the older NELA model. ACS-NSQIP may have a role in pre-assessment and consenting of emergency hiatus and diaphragmatic hernia repairs. Multi-centre prospective studies could be used to validate these findings.

A03 - BN Long Term Quality of Life Outcomes Following the Surgical Management of Complete Intrathoracic Stomach (CIS)

Abstract Background Surgery is indicated for symptomatic patients with complete intrathoracic stomach (CIS) to avoid complications (volvulus, obstruction and strangulation) associated with high morbidity. There remains limited evidence of the long-term outcomes and improvement in symptoms from this procedure. Previous large studies have been unable to compare pre-operative symptoms with their post-operative data. Although it appears the procedure has favourable outcomes, further data is required to demonstrate a significant improvement in quality of life (QoL). We therefore aim to assess the long-term outcomes, including changes to QoL and satisfaction, for patients who underwent laparoscopic biological hiatal mesh reconstruction for CIS (100%). Method Prospective data was collected from 154 consecutive GPEH (Giant Hiatus Hernia) patients intervened between March 2008- December 2023 in a large DGH. Retrospective analysis of this identified a subgroup of 34 patients with CIS. All patients underwent a laparoscopic repair with biological mesh, apart from one patient who underwent gastropexy. Outcome measures included both pre-operative and post-operative standardised GERD-Health Related Quality of Life Questionnaire (GERD-QOL) scores; complications; and patient satisfaction. Results Thirty-four patients were included (11 male:23 female) with a mean age 72 (45-83) years. All patients were symptomatic pre-operatively with heartburn (59%), dysphagia (59%), retrosternal discomfort (53%), vomiting (41%), weight loss (41%) or shortness of breath (35%). There were 4 (12%) complications and 3 (9%) 30-day mortalities. Follow up GERD-QOL questionnaires displayed 32/34 (94%) excellent scores (defined as total <5) at 6 months and 15/21 (71%) excellent scores after a median follow up of 8.5 years (72% response rate, 2 further mortalities). This demonstrated a significant improvement in scores following the procedure and long term (p<0.001). Nineteen patients (90%) were satisfied with the procedure after long term follow up (median 8.5 years). Conclusion Laparoscopic repair of complete intrathoracic stomach in this large single-centre study has demonstrated a significant improvement in symptoms and satisfaction over a median 8.5 year follow-up.

BN SO36 - Robotic versus laparoscopic giant hiatus hernia repair - is one superior in clinical outcomes?

Abstract Background The number of robotic giant hiatal hernia repair (RGHHR) procedures is steadily increasing. RGHHR offers several potential advantages over traditional laparoscopy, including enhanced visualisation, superior ergonomics, and the use of articulating instruments, which can be particularly beneficial in the restrictive operating field of the diaphragmatic hiatus. However, the outcomes of RGHHR remain heterogeneous, both when reported alone and in comparison to laparoscopic giant hiatus hernia repair (LGHHR). This study aims to evaluate and compare the key clinical outcomes of RGHHR and LGHHR in adult patients. Method All patients undergoing primary giant hiatus hernia (GHH) surgery between March 2019 and March 2024 at a tertiary institution and a five surgeon upper GI service. Retrospective review of electronic records were utilised to document: patient demographics, hernia type, operative details. Use of mesh and gastropexy (as proxy measures to indicate difficulty of operation). Follow-up duration in weeks. Open cases within this cohort were excluded. Outcomes were: length of stay (LOS), 30-day morbidity measured using Clavien-Dindo (CD) grading, RTT and 30-day mortality. Analysis was undertaken using un-paired t-test and Chi2. A p-value of <0.05 was considered statistically significant. Results Table 1. Patients LGHHR RGHHR p n 56 29 Age (median) 71 (31-93) 66 (39-85) 0.1303 Female (%) 68.7 70 0.8988 BMI 31.8 (±6.4) 29.9 (±3.4) 0.1715 ASA grade (average) 2.4 2.2 0.0587 Hernia Types (median) 3 3 0.4411 Median follow-up (weeks) 8 (1-161) 12 (3-172) 0.5763 Table 2.

Outcomes LGHHR RGHHR p LOS (median) 1 (0-161) 2 (0-15) 0.4177 30-day morbidity (CD≥3, %) 3.6 6.9 0.9193 RTT (%) 9.1 6.9 0.5570 30-day mortality 0 0 NA Conclusion RGHHR approach has been successful in managing complex GHH, with low RTT, low co-morbidity and no mortality. In our institution RGHHR has demonstrated non-inferiority to LGHHR in respect to clinical outcomes. Patient factors and hernia types did not affect case selection. Use of mesh and gastropexy showed no difference in outcomes between the two groups. Cost, operative time and surgeon strain/fatigue were not evaluated in this study, however, these would provide useful additional comparative markers for the future.

Giant Hiatal Hernia and P4HB Phasix TMST Mesh Hiatoplasty Outcomes

Surgical repair of giant hiatal hernia (GHH) and associated high recurrence rate defy technological advances in surgical sciences despite better instrumentation and availability of various mesh prostheses. Aim: This study evaluates the safety and efficacy of long-lasting biosynthetic absorbable Poly 4 Hydroxybutyrate Phasix TMST mesh outcomes in patients with GHH undergoing hiatal hernia repair. Methods: We studied a prospectively maintained database of all patients who underwent GHH repair between September 2020 and October 2023. Primary outcome measures were 30-day mortality and postoperative morbidities. Secondary outcome measures were 90-day readmission rates, patient-reported outcomes derived through modified Visick grading and recurrence of hiatus hernia. Results: 44 patients were included in this study. Median follow-up is twenty-four months. There was no mortality at 30 days. 4.5% (n=2) experienced significant complications at 30 days. Median length of stay was 3 days. 81% reported clinical improvement with enhanced Visick grade, and proton-pump inhibitor (PPI) cessation rate was 77.4%. There were no readmissions at 90 days. 9.1% who reported symptom recurrence had anatomical hiatus hernia recurrence. Conclusion: The study showed laparoscopic hiatoplasty with P4B Phasix TMST mesh has low morbidity and recurrence with medium-term follow-up.

280. MANOMETRIC FINDINGS IN PATIENTS WITH GIANT HIATAL HERNIA: OESOPHAGEAL PHYSIOLOGY APPEARS TO IMPROVE WITH SURGERY

Abstract Background High resolution manometry (HRM) is a gold standard test of oesophageal physiology. The use of HRM in patients with giant hiatus hernia (GHH) is limited by historical technical challenges as well as unclear clinical implications of the findings. The aim of this study is to demonstrate feasibility of HRM in patients with GHH and study effect of surgery on oesophageal physiology of patients undergoing GHH repair. Methods Data was extracted from a prospectively populated database of patients with giant (>30% stomach above diaphragm) hiatus hernias. All patients that underwent HRM before and after surgery were included. Manometric findings before and after surgery were analysed and compared. Patient symptoms were correlated with manometric findings. Results Inclusion criteria were met by 30 patients: 83% female, average age 74 (range 51-86), 93% had type III hernia containing on average 55% of stomach. All operations but one were performed laparoscopically. Pre-operatively average LOS length was 1.89cm which improved significantly to 2.19cm after surgery (p<0.05). Nine patients had ineffective oesophageal motility on index study which normalised post operatively in 4 patients. Lower oesophageal sphincter integrated relaxation pressure (IRP) increased post-operatively from 9.07mmHg to 11.52mmHg (p<0.05). Distal contractility improved post-operatively, however this was not significant. Most common presenting symptoms were dyspnoea, anaemia, retrosternal pain, and dysphagia. There was no association between dysphagia and manometric findings before or after surgery. Conclusion This study provides an insight into HRM findings in patients with GHH before and after surgery. Majority of the physiological parameters improved with surgery. There was no correlation of symptom of dysphagia with manometric findings.

353. INNOVATIVE SURGICAL TECHNIQUES TO REDUCE RECURRENCE IN LAPAROSCOPIC RADICAL TREATMENT OF GIANT HIATAL HERNIA

Abstract Background In Japan, there is an increasing trend in the number of esophageal hiatal hernia (EHH) surgeries performed in elderly patients. EHH in the elderly patients are associated with surgical invasiveness and complications, but safe surgery can contribute to improving quality of life (QOL). We report on the safe surgical technique and treatment results for giant hiatal hernia. Methods The most important point to be careful of when suturing the esophageal hiatus is damage to the diaphragm leg. If the esophageal hiatus is large, reducing the pneumoperitoneum pressure as much as possible will reduce the tissue resistance during suturing, allowing suture closure without placing excessive tension on the diaphragm legs. If the esophageal hiatus is large, the pneumoperitoneum pressure should be kept as low as possible to reduce tissue resistance during suturing and prevent damage to the diaphragm legs. Surgery is usually performed with a high pneumo-abdominal pressure of 10 mmHg, but if suture closure of the esophageal hiatus is difficult, suturing is performed with a low pneumo-abdominal pressure of 6 mmHg. We underwent 103 cases of EHH surgery between 2012 and 2022. There were 73 cases (70.8%) of over 75 years old patients, and 71 cases (68.9%) of giant mixed type EHH. We compared the surgical outcomes in the early group up to 2018, in which surgery was performed with high pneumo-abdominal pressure during hiatal closure, and the latter group, from 2019 onwards, in which surgery was performed with low pneumo-abdominal pressure during hiatal closure. Results 67 cases in the early group: 23 cases with sliding type/44 cases with mixed type (65.6%), 36 cases in the latter group: 8 cases with sliding type/27 cases with mixed type (75.0%), the proportion of mixed type was higher in the late group. Mesh was used in 1 case in the early group and 0 cases in the latter group. The recurrence rate was 7 cases (10.4%) in the early group and 1 case (2.8%) in the late group, and although the proportion of mixed type cases was higher in the latter group, the recurrence rate was lower. Reoperation for recurrence was performed in 1 patient in the early group. In one case of recurrent surgery in the early group, the type of recurrence was that the muscle bundle of the diaphragm leg on one side was torn, the hiatus was dilated, and the transverse colon was invaginated into the mediastinum. From this experience, I reaffirmed the importance of reliably suturing the esophageal hiatus without damaging tissue in order to reduce recurrence of giant hiatal hernia surgery. Although there are differences in observation periods, in recent years, appropriate management of intraoperative pneumoperitoneum pressure has been able to reduce recurrence and complications, and it has also been possible to safely improve QOL in elderly patients. Conclusions In giant hiatal hernia surgery, appropriate control of intraoperative pneumoperitoneum pressure can reduce recurrence.

324. A RETROSPECTIVE SINGLE CENTRE PROPENSITY-MATCHED ANALYSIS OF TRANSTHORACIC VERSUS TRANSABDOMINAL PROCEDURES FOR GIANT HIATAL HERNIAS

Abstract Background Transthoracic open procedure (TTO) was historically the preferred approach for treatment of giant hiatal hernias. However, the last decades transabdominal laparoscopic procedures (TAL) became the standard approach in many centres. The aim of the study was to compare short-term and midterm outcomes, as well as patient-reported outcome measures (PROMs, between TTO and TAL for giant hiatal hernias. Methods A retrospective analysis was conducted on all primary surgeries performed for giant hiatal hernias between 2008 and 2022. Patients who underwent TAL were propensity-matched (n= 36) to those who underwent TTO based on: age, gender, Charlson Comorbidity Score and hernia type. The two groups were compared in terms of surgery duration, length of stay (LOS), Clavien-Dindo score, intrahospital reoperation, hernia recurrence and need for reinterventions. PROMswere compared between total of TTO (n= 187) and TAL (n= 48): for symptom score, QoL-score, overall satisfaction and wound pain. Median clinical follow-up was 365.5 days. Median PROMsfollow-up was 55.3 months. Results Surgery duration (224 vs 177min, P<0.001) and LOS (11 vs 4days, P<0.001) were longer in TTO. Clavien-Dindo scores were alike (P= 0.260). Intrahospital reoperation was not statistically different (8.3% vs 0%, P= 0.239). Midterm recurrence rates suggested a non-significant trend towards lower recurrence in TTO (2.8% vs 16.7%, P= 0.107). Reintervention rates were alike (16.7% vs 11.1%, P= 0.735). QoL-score was inferior for TTO (0.705 vs 0.355, P= 0.036). Wound pain scores were higher in TTO (1 vs 0, P <0.001). Symptom score and satisfaction scores were alike, respectively 0.685 vs 0.760, P= 0.688 and 9 vs 9, P= 0.421. Conclusions TAL for giant hiatal hernias showed superior results compared to TTO for duration of surgery, length of hospital stay, QoL-score and wound pain scores. However, midterm results showed a noticeable trend towards higher recurrence rates for TAL. TAL should be considered when proceeding with surgery for giant hiatal hernias but a possible higher risk of recurrence must be taken into account. Further long-term clinical follow-up and comparison to PROMscould guide future decision-making.

495. LAPAROSCOPIC FUNDOPLICATION IMPROVES ESOPHAGEAL MOTILITY IN PATIENTS WITH GERD A HIGH VOLUME SINGLE CENTER CONTROLLED STUDY IN HIGH-RESOLUTION MANOMETRY ERA

Abstract Background Pathophysiology of GERD is complex and esophageal motility disorders are frequently contributing to the disease. Most of the existing literature demonstrates that Laparoscopic Fundoplication (LF) is safe in the setting of ineffective or weak peristalsis, however the effect of the wrap on esophageal motility is still debated. This study aimed to assess how a functioning and effective fundoplication could impact the esophageal motility in patients with GERD. Methods We analyzed prospectively collected data on patients who underwent laparoscopic Nissen (LN) or Toupet (LT) fundoplication for GERD between 2010-2022. We selected patients who have been treated with LF according to the GERD international guidelines. The exclusion criteria were: patients with a giant hiatal hernia and patients with a proof of a too-tight LF. Patients were evaluated with the GerdQ questionnaire, barium-swallow, endoscopy and HRM and 24-hour pH-Impedance before and after surgery. The HRM were reviewed by 2 experts (Chicago Classification v4.0). LF failure was recorded in case of an abnormal postoperative pH-MII using the Lyon 2.0 criteria. Results We recruited 124 patients (M:F=89:35). Fifty-eight LN and 66 LT were recorded. A good outcome at the 24-hour pH-Impedance was registered in 103 patients (GLF) and a failure in 21 patients (FLF). As shown in Figure 1, in GLF patients, 29 had a preoperative motility disorder (24 IEM and 5 DES), and postoperatively 22 (76%) of these patients had a normalization of the esophageal motility. Ten FLF patients had a preoperative motility disorder (9 IEM and one DES); 4 (40%) of them showed normal motility after LF. There was a significant association between GLF and normalization of esophageal motility (p<0.05). Conclusion This study demonstrates that LF is an effective and functioning treatment in patients with GERD associated with an esophageal motility disorder. Moreover, our results indicate that LF could determine a normalization of the disordered esophageal motor function in patients with GERD.

PHASIX™ ST MESH FOR CRURAL REINFORCEMENT DURING GIANT HIATAL HERNIA REPAIR: PRESENTATION OF SURGICAL TECHNIQUE

Abstract Aim Crural mesh reinforcement during large hiatal hernia repair has been advocated to defend against early recurrences. However, the optimal mesh material and configuration remain in question. This study presents the rationale and surgical technique for crural repair augmentation using Phasix™ ST Mesh. Methods We present a case of a giant hiatal hernia and outline the rationale and surgical technique for using Phasix™ ST Mesh in the repair. Results A 72-year-old man presented with a giant type IV hiatal hernia. A massive mediastinal protrusion of intra-abdominal fat and viscera, and an associated crucial cardiorespiratory compromise were noted. A preoperative CT scan revealed a widened hiatus measuring 9.2 × 7.6 cm. The patient underwent laparoscopic hiatal hernia repair and Nissen fundoplication. During the procedure, following visceral reduction and hernia sac dissection and excision, a widened round hiatus and significantly thinned crura were found. To reinforce the primary crural suturing, two strips of Phasix™ ST Mesh, each measuring 1.5 × 4 cm, were used, and a U-shaped mesh was placed onlay to augment the repair. The procedure lasted 214 minutes, and the patient was discharged on the 3rd postoperative day without complications. Conclusions The application of Phasix™ ST Mesh in the repair of giant hiatal hernias offers the dual benefits of reconstructing the original anatomy and reinforcing the hiatus, while avoiding the implantation of permanent foreign material around the esophagus.

Should We Operate Nonagenarians with Symptomatic Giant Paraesophageal Hernias?

Introduction: Hiatal hernia (HH) is a common disorder of the upper gastrointestinal (UGI) tract that general surgeons encounter. Giant paraesophageal is a subtype of HH in which more than 30% of the stomach is located in the chest. It can cause symptoms such as dysphagia, UGI bleeding, gastroesophageal reflux disease, and vomiting. As the life expectancy of the general population increases, the incidence of giant HH increases and can cause morbidity, including recurrent admissions and prolonged length of hospitalization. In this article, we describe a cohort of nonagenarian patients with HH who were admitted to our institution and were treated either surgically or medically. Methods: We retrospectively reviewed our prospectively maintained database of all nonagenarians who were admitted to our center between 2018 and 2022 with the diagnosis of HH. We compared the demographic data, clinical data, and outcomes between patients undergoing operative and nonoperative management. Results: Twenty patients of age over 90 years were hospitalized with HH-related symptoms. Six underwent surgery, whereas 14 received medical management. Surgical patients had fewer overall hospitalization days, shorter length of stay, and less blood product requirements. Notably two cases of in-hospital mortality occurred in the nonoperative group, whereas none occurred in the operative group. All surgical procedures were performed laparoscopically, with two minor perioperative complications. Conclusion: In selected nonagenarian patients, laparoscopic HH repair is safe and should be considered favorably. It can reduce hospitalization time and can mitigate morbidity.

Innovative esophageal lengthening surgical technique in giant hiatal hernia repair

Innovative esophageal lengthening surgical technique in giant hiatal hernia repair

A new approach to the treatment of large and giant hiatal hernia

Objective. To retrospectively analyse the results of a new technique of laparoscopic surgery for large and giant hiatal hernias of the esophageal orifice of the diaphragm, which consists in the use of diaphragmatic incisions and mesh implants to reduce the incidence of recurrence and complications.
 Materials and methods. During the period from 2010 to 2023, laparoscopic interventions were performed in 62 patients, 43 (69.4%) women and 19 (30.6%) men, with large and giant hiatal hernias of the esophageal orifice of the diaphragm. The average age of the patients was 62.8 years. The diagnostic criteria used to select patients were the size of the hiatal opening and clinical symptoms. Fibroesophagogastroduodenoscopy, abdominal computed tomography, and contrast radiography were used to assess the size of the hernia and plan surgical intervention. During the operation, we performed loosening incisions of the diaphragm to reduce the tension during suturing of hiatus defects. Progrip self–locking meshes were also used to close the diaphragmatic defects, which allowed them to be securely fixed without tension and reduce the risk of recurrence.
 Results. Most patients had comorbidities that required a special approach during surgery. The average duration of the operations was 132 minutes, which indicates their technical complexity. The postoperative course in most patients was uncomplicated with a minimal recovery period. The average hospital stay was 5.2 days. Recurrence of hernia was detected in 2 (3.2%) of 62 patients, which indicates the effectiveness of the new technique.
 Conclusions. The use of a new concept of laparoscopic surgery for large and giant hernias of the esophageal orifice of the diaphragm, which involves the performance of laxative incisions of the diaphragm and the use of self–locking mesh, significantly reduces the incidence of recurrence and complications, which ensures high treatment efficiency and improves the quality of life of patients. The results of the study confirm the importance of an individual approach to the treatment of hiatal hernias and the possibility of optimising laparoscopic techniques to improve their effectiveness.

Could "Low Quality of Life" Rather Than "Significant Symptoms" Be Better Criteria for the Selection of Patients for the Repair of a Giant Hiatus Hernia?

Purpose Giant hiatus hernia (GHH) repair is undertaken electively in symptomatic patients, to prevent complications such as gastric volvulus and subsequent mortality. Advances in laparoscopy and perioperative care have reduced the risk of GHHrepair, and improvement in quality of life (QoL) has become an important outcome measure. In our unit, we have been assessing QoL in all the operated as well as non-operated patients with GHH, using the "Quality of Life in Reflux and Dyspepsia" (QOLRAD) questionnaire. We sought to evaluate differences in QoLbetween patients who were managed conservatively for GHHand those who underwent GHH repair over a two-year period. Methods All patients seen in the Upper Gastrointestinal Tertiary Unit in Lancashire Teaching Hospitals NHS Trustwith GHH between January 2015 and December 2022 were identified from a prospectively kept database. QOLRAD scores were analyzed and compared between conservatively and operatively managed patients using the Mann-Whitney U test. Demographic and operative outcome data were also collected. Results Eighty-seven patients with GHH were included. QoL of 51 patients improved significantly after elective surgery. Five out of 36 patients, who were initially treated conservatively, elected to have repair during their follow-up period. These 5 Patients had a lower initial QOLRAD score in comparison to those whose management remained conservative (2.72 vs 5.05, Mann Whitney U testp=0.034), and their QOLRAD scores also improved significantly after the operation. QOLRAD scores in conservatively managed patients remained stable over a two-year follow-up period. Conclusion Objectively calculated low QoL may be a more useful tool than subjective symptoms in selecting patients for elective repair of GHH.

Laparoscopic proximal sleeve gastrectomy as an alternative for management of giant hiatal hernias

Background and aim: Large anatomic defects of the diaphragmatic hiatus known as giant hiatal hernias could be associated with reflux esophagitis disease (GERD) and other life-threatening complications such as gastric volvulus, ischemia and perforation, thus surgical repair is warranted. Although usually the key steps to surgical repair are reduction of the herniated stomach, complete excision of the sac, hiatus repair, and an antireflux procedure, surgery in these cases is associated with a great rate of anatomic and functional failure, therefore different techniques have been described since the original description of Collis gastroplasty designed to lengthen the short esophagus. Methods: We report here the technique and results performing proximal vertical gastrectomy or proximal sleeve gastrectomy (PSG) as an alternative in cases in which the possibility of recurrence of the hiatal hernia (HH) is high. Results: After years of follow-up after surgery, all the case patients presented here are free of gastroesophageal reflux or dysphagia symptoms, with no necessity for acid suppression medication, and no side effects of the surgery. Conclusion: The treatment of giant HH is a complex and challenging disorder to treat. PSG seems to be a good surgical alternative for the treatment of some special cases of giant HH minimizing the GERD symptoms and possible recurrences.

Determining the need for a thoracoscopic approach to treat a giant hiatal hernia when abdominal access is poor.

Giant hernias present a significant challenge for digestive surgeons. The approach taken (laparoscopic vs thoracoscopic) depends largely on the preferences and skills of each surgeon, although in most cases today the laparoscopic approach is preferred. To determine whether patients presenting inadequate laparoscopic access to the intrathoracic hernial sac obtain poorer postoperative results than those with no such problem, in order to assess the need for a thoracoscopic approach. For the retrospective series of patients treated in our hospital for hiatal hernia (n = 112), we calculated the laparoscopic field of view and the working area accessible to surgical instruments, by means of preoperative imaging tests, to assess the likely outcome for cases inaccessible to laparoscopy. Patients with giant hiatal hernias for whom a preoperative calculation suggested that the laparoscopic route would not access all areas of the intrathoracic sac presented higher rates of perioperative complications and recurrence during follow-up than those for whom laparoscopy was unimpeded. The difference was statistically significant. Moreover, the insertion of mesh did not improve results for the non-accessible group. For patients with giant hiatal hernias, it is essential to conduct a preoperative evaluation of the angle of vision and the working area for surgery. When parts of the intrathoracic sac are inaccessible laparoscopically, the thoracoscopic approach should be considered.

OGBN P31 Laparoscopic versus open repair of giant paraoesophageal herniae: a 4-year retrospective study

Abstract Background Although laparoscopic repair of giant paraoesophageal hernia (PEH) has known advantages over open repair including a reduced post-operative length of stay (LOS) and reduced post-operative pain, there has been concern amongst surgeons regarding the recurrence rate. We sought to further analyse differences in outcomes in a retrospective series of patients with giant hiatus hernia in a single tertiary centre. Methods All giant PEH receiving operative repair at a tertiary referral centre (UCLH) were reviewed retrospectively over a one-year period from July 2019-July 2022. Diagnosis was made on gastroscopy and computer tomography (CT). A giant PEH was defined as one in which the hernia contained at least 50% of the stomach. If the patient was symptomatic post-operatively they were investigated for recurrence with gastroscopy and CT. Results The laparoscopic cohort (n=14, median age of 72 years, ASA 2) had similar demographics to those receiving open repair (n=21, median age of 68 years, ASA 2.5). Median length of stay was shorter in the laparoscopic cohort compared to the open cohort (3.5 days (1-7) versus 7 days (5-9)). The laparoscopic and open cohorts had similar rates of minor complications (42.8% (6=2, Clavien Dindo 2) versus 47.6% (n=10, Clavien Dindo 2))respectively. Recurrence of reflux or dysphagia symptoms was higher in those who had a laparoscopic repair (28.6% versus 14.3%). One radiologically confirmed recurrence occurred in the open group (4.7%). Conclusions Although the benefits of a faster post-operative recovery with a shorter LOS were clear in the cohort following laparoscopic repair, a higher rate of recurrence of symptoms was evident within those receiving a laparoscopic repair. Large, controlled, prospective studies with long-term follow-up are required in order to further establish differences in outcomes between laparoscopic and open repair of giant PEH.

Dysphagia and oesophageal dilation in giant hiatus hernia: angulation of the gastro-oesophageal junction or achalasia?

The co-existence of achalasia and large para oesophageal hernia (PEH) is uncommon. The anatomical disruption of the GOJ mechanism by hiatal herniation may result in chronic angulation and secondary partial oesophageal obstruction. A unique case is described where the diagnostic uncertainty of coexistant achalasia and PEH with angulation causing chronic oesophageal obstruction existed. This case highlights the importance of multimodality workup of oesophageal disorders utilising endoscopy, fluoroscopy and manometry. Accurate identification of physiological abnormalities allowed appropriate design of operative intervention.
