613. LAPAROSCOPIC MANAGEMENT OF TYPE IV HIATAL HERNIA WITH MESH AUGMENTATION CRUROPLASTY - EXPERIENCE AT A TERTIARY CARE CENTRE

Abstract Background Type IV para-esophageal hernias, which are characterized by herniation of other organs in addition to stomach, are rare - comprising only 2-5% of all para-esophageal hernias. They are associated with life-threatening complications such as strangulation or perforation of stomach. Laparoscopic treatment of these hernias requires excellent advanced laparoscopic suturing and dissecting skills. Although laparoscopic approach is now universally accepted, the role of mesh augmentation remains debated. Methods Case records of patients who underwent Laparoscopic mesh augmentation cruroplasty for Type IV hiatal hernia since 2012 were retrospectively analyzed. Results Out of 340 patients who underwent hiatal hernia repair, 7 patients (3males, 4females) fulfilled the selection criteria. Median age was 64(53-89) years. Median duration of symptoms was 2months (15days-6months). All patients complained of heartburn. Vomiting was present in 5(71%) patients; only 1(14%) patient had persistent vomiting with dysphagia. Respiratory symptoms were present in 2(29%) patients. No patient had features of peritonitis or sepsis. One patient had undergone laparoscopic heller’s cardiomyotomy twice before. All patients underwent MDCT which confirmed type IV paraesophageal hernia. Median operating time was 150(100-280) minutes. Median blood loss was 150(50-400) ml. 6(85%) patients had herniation of omentum in addition to stomach while 1 patient had herniation of omentum and transverse colon. No patient had ischemia/perforation of stomach. Median hiatal defect was 6(5-8) cm. Sac was excised completely in all cases following reduction of contents. Crural repair was done with1-0 polyester interrupted sutures. In some patients, anterior cruciate ligament repair was done to avoid tenting of esophagus. Rectangle shaped Composite mesh with key-hole slit in upper border was placed. Mesh was anchored with interrupted 1-0ethilon sutures. Fundoplication (Nissen’s/Toupet) was done in all patients, none required esophageal lengthening procedure. Median post-operative stay was 5(2-8) days, median ICU stay was 1(0-4) days. Oral liquids were started on 2 nd (1-3) post-op day and solids on 4 th (2-5) day. 2(29%) patients had post- operative complications - atrial fibrillation and transient respiratory failure respectively. Median follow-up was 14(1-40) months. No patient had symptomatic recurrence. OGDscopy at 6months was normal in 5 patients. No mesh related complication was observed. Discussion Wide hiatal defects were noted in all patients. This necessitated mesh augmentation of crural repair. Both short-term (morbidity, mortality) and long-term outcomes (recurrence, patient satisfaction) were excellent.

Management Strategies and Outcomes of Distal Congenital Esophageal Strictures in the Setting of Long-gap Esophageal Atresia

BackgroundThe management of neonates with long-gap esophageal atresia (LGEA) combined with distal congenital esophageal strictures (CES) is challenging. We sought to review our approach for this rare set of anomalies. MethodsWe reviewed children with LGEA + CES surgically treated at two institutions (2018–2024). LGEA repair was performed using the Foker technique (traction-induced esophageal lengthening). A CES strategy was chosen based on preoperative evaluations and intraoperative findings. The configuration and length of the CES were assessed using retrograde flexible esophagoscopy via gastrostomy with contrast fluoroscopy. ResultsEight patients (75% male) with LGEA + CES were treated: Four had type A and four had type B EA. Median gap length was 3.5 cm. Three underwent thoracoscopic esophageal lengthening. After a median follow-up of 18 months (IQR: 9–25), all retained their native esophagus. However, those who had CES resection concurrent with the lengthening process or at the time of EA anastomosis had more challenging perioperative courses: one required additional time on traction and another required esophageal anastomotic stricture resection. ConclusionsOur experience with LGEA and distal CES emphasizes tailoring surgical approaches to each patient's unique condition, avoiding a one-size-fits-all strategy. However, if the esophageal tissue above the distal CES is in good condition, our preference has shifted towards retaining the CES during traction, performing gentle dilation at anastomosis time, and conducting definitive endoscopic management subsequently. We would caution against making the assumption that salvage of the native esophagus is not possible or that resection of the CES is always needed. Level of EvidenceLevel III.

Experience in the treatment of long-gap esophageal atresia by intraluminal esophageal stretching elongation.

To summarize the experience with intraluminal esophageal stretching elongation (ILESE) in the successful treatment of long-gap esophageal atresia (LGEA) at a single center. Clinical data of 68 neonates who underwent LGEA between February 2015 and January 2022 were retrospectively analyzed. Four patients died of multiple associated severe malformations and did not undergo ILESE. Esophageal anastomosis was successfully performed in 60 cases (93.75%) and failed in 4 cases (6.25%) treated with ILESE. The ILESE techniques, esophageal reconstruction, results, postoperative complications, and follow-up treatment were analyzed. The beginning time of performing ILESE preoperation was 53.4 ± 39.4 days after birth, and the age of esophageal reconstruction was 122.2 ± 70.3 days after birth in 60 cases. The gap length of proximal and distal esophageal segments which were evaluated the first time at admission was 4.8 ± 1.3 vertebral bodies, whereas the gap before anastomosis was -0.46 ± 0.90 vertebral bodies. Among the patients with esophageal primary-anastomosis, 55 received thoracoscopic surgery, and 5 underwent thoracotomy in the early stage. Of the 60 children with ILESE, 58 underwent end-to-end esophagostomy, of which 17 cases were combined with circular esophagotomy (livaditis), and 2 cases of esophageal lengthening were combined with the reversal of the ligulate loop of the proximal esophagus (flap). Overall, 59 cases were cured (98.3%), and 1 patient died of respiratory failure postoperatively. All patients were followed up for 7-96 months. Postoperative anastomotic leakage occurred in 16 patients (27.6%), all of whom were successfully treated conservatively. Anastomotic stenosis occurred in 49 cases (83.1%), all of which were successfully managed by non-surgical treatment, including 12.7 ± 9.3 times of esophageal balloon dilatation and 2 cases of stent dilatation. Gastroesophageal reflux occurred in 44 patients (74.6%), including associated or acquired esophageal hiatal hernia in 22 patients, and Nissen fundoplication was performed in 17 patients. ILESE is an effective method for prolonging the proximal and distal esophagus of the LGEA to reconstruct esophageal continuity using its esophageal tissue, with an efficacy rate of 93.75%. Postoperative anastomotic stricture and gastroesophageal reflux are common and require long-term, standardized follow-up and treatment.

Thoracoscopic Stage Internal Traction Repair Reduces Time to Achieve Esophageal Continuity in Long Gap Esophageal Atresia.

Management of long gap esophageal atresia (LGOA) is controversial. This study aims at comparing the management of LGOA between two high-volume centers. We included patients with LGOA (type A and B) between 2008 and 2022. Demographics, surgical methods, and outcomes were collected and compared. The study population involved 28 patients in center A and 24 patients in center B. A surgical approach was thoracoscopic in center A, only for one patient was open for final procedure. In center B, 3 patients were treated only thoracoscopically, 2 converted to open, and 19 as open surgery. In center A primary esophageal anastomosis concerned 1 case, two-staged esophageal lengthening using external traction 1 patient, and 26 were treated with the multistaged internal traction technique. In 24 patients a full anastomosis was achieved: in 23 patients only the internal traction technique was used, while 1 patient required open Collis-Nissen procedure as final management. In center B primary anastomosis was performed in 7 patients, delayed esophageal anastomosis in 8 patients, esophageal lengthening using external traction in 1 case, and 9 infants required esophageal replacement with gastric tube. Analyzed postoperative complications included: early mortality, 2/28 due to accompanied malformations (center A) and 0/24 (center B); anastomotic leakage, 4/26 (center A) treated conservatively-all patients had a contrast study-and 0/24 (center B), 1 case of pleural effusion, but no routine contrast study; recurrent strictures, 13/26 (center A) and 7/15 (center B); and need for fundoplication, 5/26 (center A) and 2/15 (center B). Age at esophageal continuity was as a median of 31 days in center A and 110 days in center B. Median time between initial procedure and esophageal anastomosis was 11 days in center A and 92 days in center B. Thoracoscopic internal traction technique reduces time to achieve esophageal continuity and the need for esophageal substitution while maintaining a similar early complication rate.

What Proportion of Children With Complex Oesophageal Atresia Require Oesophageal Lengthening Procedures?

IntroductionBabies with oesophageal atresia (OA) who cannot achieve a primary anastomosis (complex OA) may be treated by attempted oesophageal lengthening. We contrast reported outcomes of lengthening with our experience of managing complex OA. Patients and methodsA consecutive series treated in an English regional centre was completed. Outcomes of interest were the rate of retention of the native oesophagus, complications requiring thoracotomy, rates of anastomotic leak, stricture, fundoplication, and mortality. Possible explanatory variables were the surgical techniques applied. Results29/215 (13%) OA were complex, and 25/207 survived to repair. 14/25 (56%) had no distal fistula, pure OA, while 11/25 (44%) had a long gap with distal fistula. 18/25 (72%) had delayed primary anastomosis, while 7/25 (28%) required oesophageal replacement. However, 2 of the replacements were salvage procedures following failed traction. Only 4/207 (2%) of OA were potentially treatable by traction. Salvage surgery was required in 2/23 (9%) complex OA not subjected to lengthening. The native oesophagus was retained without utilising lengthening in 200/207 (97%). Amongst complex OA where traction techniques had not been attempted, the native oesophagus was retained in 18/23 (78%) of cases, with median time to oesophageal continuity of 77 days. There was no in hospital mortality following treatment of complex OA, and overall survival was identical to non-complex OA among cases surviving to anastomosis. DiscussionManagement of complex OA without lengthening procedures leads a similar rate of retention of the native oesophagus as reports describing lengthening, but with significantly less morbidity. We see little need for oesophageal lengthening in the management of complex OA. Level of EvidenceIV.

210. BIORESORBABLE SYNTHETIC MESHES IN LARGE PARAESOPHAGEAL HERNIAS. TECHNIQUE OF APLICATION AND EARLY RESULTS

Abstract Background Large paraesophageal hernias (LPEH) are still a challenge faced by foregut surgeons. Surgical options are highly debated among specialists; esophageal lengthening procedures, diaphragmatic relaxing incisions, gastropexy and—mesh reinforcement. Severe complications related to synthetic meshes has led many surgeons to avoid this type of reinforcement. However, newly developed synthetic bioresorbable meshes have been used as an alternative for hiatal reinforcement, lowering the rates of recurrence without the drawbacks of synthetic materials. Methods From April 2018 to February 2023, 65 patients underwent LPEH repair with hiatal augmentation with an inverted C-shape bioresorbable mesh. All surgeries were performed by two surgeons (AB and NCA). The meshes (Bio-A®—Gore® and Phasix ST®—BARD) were applied over crurorrhaphy, covering the anterior and posterior aspects of the hiatus and secured in place with sutures and cyanoacrylate. The choice of mesh was determined by the surgeon’s preference. Follow up visits were at 1, 6 and 12 months and yearly after that. Results There were 34 patients where Bio-A was used and 31 with Phasix. Median age (55,5 vs 54,8 years) didn’t differ between groups. LPEH were primary (PS) in 39 patients and recurrence from prior interventions (RS) in 26. Median age was higher in PS (58,6 vs 49,6 years). There were no intraoperative complications related to the use of mesh. The patients were discharged after 24–48 hours. The average follow-up period was similar between PS and RS (10,1 vs 9,6 months). There were three recurrences (2 Bio-A, 1 Phasix) in PS (7,6%) and seven (26,9%) in RS (2 Bio-A, 5 Phasix). There weren’t complaints of prolonged dysphagia or need for dilatation. Nine out of 10 recurrences are small. One large recurrence, required reintervention for acute volvulus after 1 year (RS group with Phasix). Conclusion bioresorbable meshes are safe to use as a reinforcement of hiatoplasty in LPEH. They can reduce recurrence and reoperation rates in PS at a short term follow-up. Large recurrent hiatal hernias still present as a major challenge and adjuvant techniques should be employed to further reduce recurrences.

Robotic Primary and Revisional Hiatal Hernia Repair is Safe and Associated with Favorable Perioperative Outcomes: A Single Institution Experience.

Background: Robotic hiatal hernia (HH) repair has been demonstrated to be feasible and safe. Recent conflicting reports have emerged on the higher incidence of perioperative complications with robotic HH repair when compared with laparoscopic repair. Materials and Methods: A retrospective review of a prospective database at an academic medical center for all robotic HH repairs performed by a high-volume foregut surgeon from 2018 to 2021 was performed. Outcome measures included operative time, estimated blood loss (EBL), length of stay (LOS), conversion rate, need for esophageal lengthening procedure, intra- and perioperative complications, and 30-day in-hospital mortality. Results: One hundred four patients were included in the analysis. Fifteen percent of patients had a type I HH, 2% had a type II, 73% had a type III, and 10% had a type IV HH. Eighty-four percent of cases were primary and 16% were revisional. Fifty-four percent of patients had mesh placed and 4.4% had an esophageal lengthening procedure. Mean EBL was 15 mL and mean operative time was 151 minutes. Median LOS was 2 days (interquartile range 1-2 days). There were zero conversions. Intraoperative complication rate was 1% and 30-day complication rate was 4%. The 30-day in-hospital mortality was zero. Conclusion: In this retrospective analysis of 114 consecutive robotic HH repairs performed, with 83% type III or IV HHs and 16% revisional hiatal cases, our results demonstrate favorable perioperative outcomes, with lower EBL, shorter LOS, lower complication rate, zero conversions, and comparable operative times compared with historical laparoscopic data.

Long gap esophageal atresia repair using the foker tecnique: a 19 years experience.

Esophageal atresia (EA) with a 3-cm gap or longer and a very short distal segment represents the extreme of this disorder's spectrum, the treatment of which can be challenging. Management of newborns with long-gap esophageal atresia (LGEA) remains a challenge for pediatric surgeons. The inclusion criteria in the study were as follows: long gap esophageal atresia, Foker technique, at least 10 years follow up. We sought to examine our experiences with LGEA using Foker technique. RESULTS: From 2001 to 2020 were operated for esophageal atresia at the UOC Surgery of the AORN Santobono 290 children of whom 16 patients meet our inclusion criteria. 6 had a type I EA, 2 had a type II and 8 had a type III. Mean gap length was 4 cm (range 3-5), In 9 patients gastrostomy and Foker technique was performed in the same time (around the 1stto the 4th day of life), while in 7 patients gastrostomy was performed in 1st-2nd day of life and the Foker technique was delayed due to clinical needs with a mean of 76 days (range 26-96 days) . In the study group, 11/16 (68,75%) patients underwent multiple endoscopic dilatations ( means 5 sessions per patient); 3 out of 16 cases of early complications occurred: 2 perforations and 1 dehiscence. Gastroesophageal reflux was common during the first 6 years of life and 2 had a fundoplication due to gastroesophageal reflux disease resistant to maximal medical therapy and 1 had an esophageal diverticulum at 5 years. 7 out of 16 (43,7%) (average age 13,5 years) perform therapy cycles with pump inhibitors for an average period of 12 weeks. CONCLUSIONS: Foker procedure for esophageal lengthening in patients with LGEA was successful in mobilizing the esophagus and obtaining a repair in the majority of our patients after 12 to 15 days of traction and it should be considered in LGEA cases to preserve the native esophagus as often as possible.

Qualitative features of esophageal fluorescence angiography and anastomotic outcomes in children

BackgroundIndocyanine green (ICG) is commonly used to assess perfusion, but quality defining features are lacking. We sought to establish qualitative features of esophageal ICG perfusion assessments, and develop an esophageal anastomotic scorecard to risk-stratify anastomotic outcomes. MethodsSingle institution, retrospective analysis of children with an intraoperative ICG perfusion assessment of an esophageal anastomosis. Qualitative perfusion features were defined and a perfusion score developed. Associations between perfusion and clinical features with poor anastomotic outcomes (PAO, leak or refractory stricture) were evaluated with logistic and time-to-event analyses. Combining significant features, we developed and tested an esophageal anastomotic scorecard to stratify PAO risk. ResultsFrom 2019 to 2021, 53 children (median age 7.4 months) underwent 55 esophageal anastomoses. Median (IQR) follow-up was 14 (10–19.9) months; mean (SD) perfusion score was 13.2 (3.4). Fifteen (27.3%) anastomoses experienced a PAO and had significantly lower mean perfusion scores (11.3 (3.3) vs 14.0 (3.2), p = 0.007). Unique ICG perfusion features, severe tension, and primary or rescue traction-induced esophageal lengthening [Foker] procedures were significantly associated with PAO on both logistic and Cox regression. The scorecard (range 0–7) included any Foker (+2), severe tension (+1), no arborization on either segment (+1), suture line hypoperfusion >twice expected width (+2), and segmental or global areas of hypoperfusion (+1). A scorecard cut-off >3 yielded a sensitivity of 73% and specificity of 93% (AUC 0.878 [95%CI 0.777 to 0.978]) in identifying a PAO. ConclusionsA scoring system comprised of qualitative ICG perfusion features, tissue quality, and anastomotic tension can help risk-stratify esophageal anastomotic outcomes accurately.

Feasibility of delayed anastomosis for long gap esophageal atresia in the neonatal period using internal traction and indocyanine green-guided near-infrared fluorescence.

Management of neonates with long gap esophageal atresia (LGEA) is one of the most challenging situations facing pediatric surgeons. Delayed anastomosis after internal traction for esophageal lengthening was reported as a useful technique for long gap cases. Additionally, the use of near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) has gained popularity in pediatric surgery, especially for blood perfusion validation. We report a novel technique for safe and secure anastomosis for LGEA in the neonatal period using internal traction and ICG-guided NIR fluorescence. A pregnant woman with polyhydramnios was admitted to the department of obstetrics in our hospital. At 29 weeks of gestation, ultrasound showed mild polyhydramnios and absence of the fetal stomach. A male neonate was born at 38 weeks of gestation with 21 trisomy. EA (Gross type A) was diagnosed based on an X-ray study that showed the absence of gastric bubble with a nasogastric tube showing the "coil-up" sign. Thoracoscopic internal traction and laparoscopic gastrostomy were performed on day 4 after birth. We confirmed the distance between the upper pouch and lower pouch on X-ray. On day 16 after birth, thoracoscopic anastomosis was performed. We successfully performed esophageal anastomosis without tearing the esophageal wall. Blood perfusion of the upper and lower pouch was validated after anastomosis using ICG-guided NIR fluorescence. Delayed anastomosis for LGEA in the neonatal period using internal traction and ICG-guided NIR fluorescence is safe and feasible.

Biomechanics of esophageal elongation with traction sutures on experimental animal model

Esophageal elongation is one of the methods of long gap esophageal atresia treatment. The aim of the study was to determine the best type of traction suture for esophageal lengthening on an animal model. White Pekin Duck’s esophagi were used as a model (fresh-frozen and thawed). The esophagus was cut in half, then both ends were sutured together and extended on a tensiometer. Tested sutures involved simple suture, suture aided by a single or double clip, and suture aided by pledget (10 samples each). Constant and 2 methods of intermittent traction were also compared. The histological study showed similarities between duck’s and newborn’s esophagus. The highest maximal force was achieved with pledget suture (F = 8.59 N ± 1.45 N), then with double clip (F = 5.74 N ± 1.29 N) and the lowest with single suture (F = 3.80 N ± 0.54 N) (p < 0.001). Pledget suture also allowed for the greatest elongation (p < 0.01). Intermittent traction results in better elongation at the same breaking strength as constant traction (p < 0.05) if traction is maintained during breaks. Reinforced sutures (pledget or double clip) should be taken into consideration in internal traction. When performing traction sutures, it is worth step by step carefully tightening the sliding knot in short periods before its final binding.

How I Do It: Collis Gastroplasty

A key principle of hiatal hernia repair is mitigation of tension. While considerable emphasis is placed on the radial tension of the crural closure itself, of equal importance is assuring that axial tension on the esophagus is appropriately addressed. Because of this, esophageal lengthening procedures such as the transabdominal laparoscopic wedge Collis gastroplasty described here have been proposed. Such esophageal lengthening procedures allow for the creation of additional length of tubularized stomach to create a neo-esophagus that will allow for a tension free and appropriately sized fundoplication to be performed.

Esophageal Interventions in Infants Born with Esophageal Atresia: A Comprehensive Analysis of a National Database.

Esophageal atresia (EA) is a rare malformation that often requires a series of procedures, including surgical primary anastomosis, staged repair, and endoscopic procedures. Actual numbers and trends in interventions and variety in treatment strategies remain unclear. Data from the German federal bureau of statistics containing all EA-related inpatient procedures encoded from 2005 until 2018 were analyzed for children during the first year of life. The sum of esophageal anastomoses and replacements was used to calculate an estimate of incidence of EA. Over 14 years, 12,627,888 inpatient cases were recorded in infants in Germany. The mean incidence of EA was 1 per 4,217 live births. On average, 163.3 (95% confidence interval [CI]: 150.8-176.1) esophageal anastomoses, 11.2 (95% CI: 8.7-13.7) esophageal lengthening procedures, and 6.7 (95% CI: 5.42-8.00) esophageal replacements were recorded annually. Overall, 187.8 (95% CI: 147.1-200.4) endoluminal treatments (ballon dilatation, bougienage, stent placement, or injection) were performed per 100 anastomoses. Over the years, bougienage was increasingly replaced by ballon dilatation as primary treatment. Boys had a significantly higher number of esophageal procedures than girls, but the incidence of endoscopic treatments in relation to anastomoses was the same for both genders. The low incidence of EA in relation to a relatively large number of units treating those patients in Germany may pose challenges for maintaining competency and training of all specialists involved. The number of esophagoscopic treatments for esophageal stricture per anastomosis is lower than previously estimated.

Oesophageal lengthening by traction in oesophageal atresia: The UK experience

AIMSPreliminary reports suggest a promising role for oesophageal lengthening by traction (OLBT) in long gap oesophageal atresia (LGOA). Nevertheless, these encouraging results originate from specialist centres, and real-world experience is unquantified. We report the first multicentre, nationwide study of OLBT. METHODSCumulative experience of OLBT was recorded through a questionnaire sent to all UK paediatric surgery centres. OLBT was defined as “any attempt to increase oesophageal length using tension sutures”. Contributors submitted all cases of attempted OLBT, regardless of outcome. Demographics, surgical detail, and outcomes were analysed with summary statistics. RESULTSThe response rate was 23/26 centres. Eleven centres reported using OLBT in 22 patients (2003-2020) with 117 LGOA treated by other means. One patient died from complications of cardiac surgery and was excluded. OLBT enabled oesophageal anastomosis in 16 (76%), of which 2 died of complications of surgery, and another died of unrelated disease. Of the survivors, 7 required oesophageal dilatation 2-14 times. Oesophageal anastomosis was not achieved in 5 (24%) patients. All had pouch leak or disruption pre- or peri-operatively and underwent cervical oesophagostomy with subsequent gastric pull-up. One patient required dilatation of the oesophagogastric anastomosis. CONCLUSIONOLBT is being carried out in the UK in a limited number of centres in a minority of patients. These data suggest OLBT enables oesophageal anastomosis in 76% of infants with LGOA. Oesophageal pouch leak or disruption was common to all instances of failure to anastomose. Our findings will inform discussions between surgeons and families of babies born with LGOA.

Single session per oral endoscopic myotomy and trans oral incisionless fundoplication – can we prevent reflux in patients with achalasia?

Background and study aims The rate of gastroesophageal reflux disease (GERD) after per oral endoscopic myotomy (POEM) is concerning. Endoscopic anti-reflux methods, such as Trans Oral Incisionless Fundoplication (TIF), are crucial for the long-term success of POEM, especially if they can be performed in the same session. Methods We completed a proof-of-concept canine pilot study (n = 6) to assess safety and feasibility of POEM and TIF in a single session (POEM-TIF). Subsequently, POEM-TIF was also performed in patients with achalasia (n = 5). Herein, we report on the safety, technical and clinical success of the first-in-human cases with symptom follow-up at 1, 3 and 6 months and pH testing at 6 months. Results POEM was completed successfully in six canines (3 anterior and 3 posterior myotomies), followed by TIF in the same session. Necropsy and extensive testing demonstrated no evidence of mucosal injury and no leaks. The reconstructed valve was 220 to 240 degrees, 3 to 4 cm in length, and resulted in concomitant esophageal lengthening (2–5 cm). Using similar principles, the first-in-human cases were performed without intraprocedural or delayed adverse events. pH testing at 6 months showed that four of five patients had no evidence of GERD (DeMeester > 14.72), and in one case, there was evidence of esophagitis. Conclusions Single session POEM-TIF appears to be safe and feasible. Early clinical human data suggests that it may be able to reduce post POEM GERD, however the additional secondary benefits such as lengthening and straightening of the esophagus, may prove to be equally important for the long-term success of POEM.

Surgical treatment of recalcitrant gastroesophageal reflux disease in patients with systemic sclerosis: a systematic review

IntroductionGastroesophageal reflux disease (GERD) is frequently seen in patients with systemic sclerosis (SSc). Long-standing GERD may cause esophagitis, long-segment strictures, and Barrett’s esophagus and may worsen pre-existing pulmonary fibrosis with an increased risk of end-stage lung disease. Surgical treatment of recalcitrant GERD remains controversial. The purpose of this systematic review was to summarize the current data on surgical treatment of recalcitrant GERD in SSc patients.Materials and methodsA systematic literature review according to PRISMA and MOOSE guidelines. PubMed, EMBASE, and Web of Science databases were consulted.ResultsA total of 101 patients were included from 7 studies. The age ranged from 34 to 61 years and the majority were females (73.5%). Commonly reported symptoms were heartburn (92%), regurgitation (77%), and dysphagia (74%). Concurrent pulmonary disease was diagnosed in 58% of patients. Overall, 63 patients (62.4%) underwent open fundoplication, 17 (16.8%) laparoscopic fundoplication, 15 (14.9%) Roux en-Y gastric bypass (RYGB), and 6 (5.9%) esophagectomy. The postoperative follow-up ranged from 12 to 65 months. Recurrent symptoms were described in up to 70% and 30% of patients undergoing fundoplication and RYGB, respectively. Various symptoms were reported postoperatively depending on the type of surgical procedures, anatomy of the valve, need for esophageal lengthening, and follow-up.ConclusionsThe treatment of recalcitrant GERD in SSc patients is challenging. Esophagectomy should be reserved to selected patients. Minimally invasive RYGB appears feasible and safe with promising preliminary short-term results. Current evidence is scarce while a definitive indication about the most appropriate surgical treatment is lacking.
