RESUMO
BACKGROUND: Retrosternal oesophageal reconstructions with collar anastomoses can become necessary when the stomach is either unavailable for oesophageal replacement, or orthotopic reconstruction is deemed impractical. Our aim was to analyse our results regarding technical approaches and outcomes. MATERIALS AND METHODS: All patients undergoing primary and secondary oesophageal retrosternal reconstructions with collar anastomoses at our centre (2019-2023) were retrospectively analysed and individual surgical reconstruction options were presented. RESULTS: Overall, twelve patients received primary (n = 5; 42.7%) or secondary (n = 7; 58.3%) reconstructions; ten with colonic interposition and two with gastric pull-up. Male/female ratio was 4:8; median age 66 years (30-87). Charlson-Comorbidity-Score (CCS) was 5 (1-7); 8/12 patients (67%) had ASA-classification score ≥ 3. We observed no conduit necrosis, but one patient (8.3%) with a leakage of the oesophago-colonostomy which was successfully treated by endoscopic vacuum therapy. Four patients (33.3%) acquired nosocomial pneumonia. Additional drainages for pleural fluid collections were necessary in three patients (25%). Overall comprehensive-complication-index (CCI) was 26.2 (0-44.9). Length-of-stay (LOS) was 22 days median (15-40). There was no 90-days mortality. Overall, CCI during the follow-up (FU) period at median 26 months (16-50) was 33.7 (0-100). 10 out of 12 patients were on sufficient oral nutrition at 12 months FU. CONCLUSION: Primary and secondary oesophageal retrosternal reconstructions encompass diverse entities and typically requires tailored decision-making. These procedures, though rare, are feasible with acceptable complication rates and positive functional outcomes when performed in experienced hands.

INTRODUCTION: esophageal replacement in children is indicated when it is impossible to maintain the native esophagus, which in the pediatric population includes patients with esophageal atresia and esophageal caustic stenosis. The objective of this communication is to report the experience of a university service with two techniques of esophageal replacement. METHODS: this is a retrospective study based on the revision of hospital files. The study population consisted of patients who underwent esophageal replacement from 1995 to 2022, at the Hospital de Clínicas of the State University of Campinas. The analyzed data were age, sex, underlying disease, technical aspects, complications, and long-term results. RESULTS: during the study period, 30 patients underwent esophageal replacement. The most common underlying diseases were esophageal atresia (73.33%) and caustic stenosis (26.67%). Twenty-one patients underwent gastric transposition (70%), and nine underwent esophagocoloplasty (30%). The most frequent postoperative complication was fistula of the proximal anastomosis, which occurred in 14 patients. Most of the patients with fistulas had a spontaneous recovery. There were three deaths. Of the 27 survivors, 24 can feed exclusively by mouth. CONCLUSION: esophageal replacement in children is a procedure with high morbidity and mortality. Esophagocoloplasty and gastric transposition have similar results and complications, with the exception of proximal anastomotic fistulas, which are generally self-resolving and are more common in esophagocoloplasty. The choice of the best surgical technique must be individualized according to the patients characteristics and the surgeons experience, as both techniques offer the ability to feed orally in the short or medium term.

BACKGROUND: Pediatric surgeons have faced esophageal reconstruction challenges for decades owing to a variety of congenital and acquired conditions. This work aimed to introduce a reproducible and efficient approach for creating tissue-engineered esophageal tissue using bone marrow mesenchymal stem cells (BMSCs) cultured in preconditioned mediums seeded on a sheep decellularized tunica vaginalis (DTV) scaffold for partial reconstruction of a rabbit's esophagus. METHODS: DTV was performed using SDS and Triton X-100 solutions. The decellularized grafts were employed alone (DTV group) or after recellularization with BMSCs cultured for 10 days in preconditioned mediums (RTV group) for reconstructing a 3 cm segmental defect in the cervical esophagus of rabbits (n = 20) after the decellularization process was confirmed. Rabbits were observed for one month, after which they were euthanized, and the reconstructed esophagi were harvested for histological analysis. RESULTS: Six rabbits in the DTV group and eight rabbits in the RTV group survived until the end of the one-month study period. Despite histological examination demonstrating that both grafts completely repaired the esophageal defect, the RTV graft demonstrated a histological structure similar to that of the normal esophagus. The reconstructed esophagi in the RTV group revealed the arrangement of the different layers of the esophageal wall with the formation of newly formed blood vessels and Schwann-like cells. CONCLUSION: DTV xenograft is a novel scaffold that promotes cell adhesion and differentiation and might be effectively utilized for regenerating esophageal tissue, paving the way for future clinical trials in pediatric patients.

BACKGROUND: Adverse gastric symptoms persist in up to 20% of fundoplication operations completed for gastroesophageal reflux disease, causing significant morbidity and driving the need for revisional procedures. Noninvasive techniques to assess the mechanisms of persistent postoperative symptoms are lacking. This study aimed to investigate gastric myoelectrical abnormalities and symptoms in patients after fundoplication using a novel noninvasive body surface gastric mapping (BSGM) device. METHODS: Patients with a previous fundoplication operation and ongoing significant gastroduodenal symptoms and matched controls were included. BSGM using Gastric Alimetry (Alimetry Ltd) was employed, consisting of a high-resolution 64-channel array, validated symptom-logging application, and wearable reader. RESULTS: A total of 16 patients with significant chronic symptoms after fundoplication were recruited, with 16 matched controls. Overall, 6 of 16 patients (37.5%) showed significant spectral abnormalities defined by unstable gastric myoelectrical activity (n = 2), abnormally high gastric frequencies (n = 3), or high gastric amplitudes (n = 1). Patients with spectral abnormalities had higher Patient Assessment of Upper Gastrointestinal Disorders-Symptom Severity Index scores than those of patients without spectral abnormalities (3.2 [range, 2.8-3.6] vs 2.3 [range, 2.2-2.8], respectively; P = .024). Moreover, 7 of 16 patients (43.8%) had BSGM test results suggestive of gut-brain axis contributions and without myoelectrical dysfunction. Increasing Principal Gastric Frequency Deviation and decreasing Rhythm Index scores were associated with symptom severity (r > .40; P < .05). CONCLUSION: A significant number of patients with persistent postfundoplication symptoms displayed abnormal gastric function on BSGM testing, which correlated with symptom severity. Our findings advance the pathophysiologic understanding of postfundoplication disorders, which may inform diagnosis and patient selection for medical therapy and revisional procedures.

Historically, children afflicted with long gap esophageal atresia (LGEA) had few options, either esophageal replacement or a life of gastrostomy feeds. In 1997, John Foker from Minnesota revolutionized the treatment of LGEA. His new procedure focused on "traction-induced growth" when the proximal and distal esophageal segments were too far apart for primary repair. Foker's approach involved placement of pledgeted sutures on both esophageal pouches connected to an externalized traction system which could be serially tightened, allowing for tension-induced esophageal growth and a delayed primary repair. Despite its potential, the Foker process was received with criticism and disbelief, and to this day, controversy remains regarding its mechanism of action - esophageal growth versus stretch. Nonetheless, early adopters such as Rusty Jennings of Boston embraced Foker's central principle that "one's own esophagus is best" and was instrumental to the implementation and rise in popularity of the Foker process. The downstream effects of this emphasis on esophageal preservation would uncover the need for a focused yet multidisciplinary approach to the many challenges that EA children face beyond "just the esophagus", leading to the first Esophageal and Airway Treatment Center for children. Consequently, the development of new techniques for the multidimensional care of the LGEA child evolved such as the posterior tracheopexy for associated tracheomalacia, the supercharged jejunal interposition, as well as minimally invasive internalized esophageal traction systems. We recognize the work of Foker and Jennings as key catalysts of an era of esophageal preservation and multidisciplinary care of children with EA.

Despite improving the survival after repair of esophageal atresia (EA), the morbidity of EA repair remains high. Specifically, tracheomalacia (TM) is one of the most frequent complications of EA repair. Continuous positive airway pressure is generally applied for the treatment of TM. However, surgical intervention is required against an apparent life-threatening event or inability to perform extubation for a long period. According to our review, most cases of TM showed symptom improvement after aortopexy. The ratio of the trachea's lateral and anterior-posterior diameter at the brachiocephalic artery crossing the trachea, which reflects the compression of the trachea by the brachiocephalic artery, is a good indicator of aortopexy. Our finding suggests that most TM cases associated with EA may not be caused by tracheal fragility alone, but may involve blood vessel compression. Posterior tracheopexy (PT) is also an effective treatment for TM. Recently, open or thoracoscopic PT was able to be performed simultaneously with EA repair. In many cases, aortopexy or PT is a safe and effective surgical treatment for TM with EA. Other surgical procedures, such as external stenting, should be considered for patients with diffuse-type TM for whom aortopexy and PT appear relatively ineffective.

INTRODUCTION: Babies 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 METHODS: A 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. RESULTS: 29/215 (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. DISCUSSION: Management 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 EVIDENCE: IV.

OBJECTIVE: To evaluate the possibilities of intraoperative indocyanine green fluorescein angiography (ICG technology) in primary esophagoplasty by gastric conduit in patients with malignant tumors of the esophagus. MATERIAL AND METHODS: The study included 74 patients. Depending on the localization of the tumor in the esophagus, a Lewis-type or McKeown-type operation was performed. The retrospective group (surgery without the use of ICG technology) included 53 patients who underwent surgery from 2015 to 2020 years.The prospective group (surgery with the use ICG technology) included 21 patients operated on from 2021 to 2023 years. ICG technology was used to assess microcirculation in the gastric conduit during esophagoplasty, as well as to identify the right gastroepiploic artery. RESULTS: The ICG fluorescein angiography technique for assessing microcirculation in the gastric conduit was a simple and easily reproducible procedure. Perfusion of the gastric conduit was regarded as satisfactory in 16 (76%) cases, unsatisfactory in 5 (24%) cases, which required resection of the distal part of the conduit. All cases of poor perfusion were in patients with narrow gastric conduit and neck anastomosis location (McKeown-type operation). Anastomotic leakages occurred in 8 (15%) patients in the retrospective group, 4 (19%) patients in the prospective group (p>0.05). In 4 out of 5 cases of poor gastric conduit perfusion, anastomotic leaks occurred. Immediate postoperative results in the compared groups were also comparable. The use of ICG technology in 5 (45%) cases out of 11, when laparoscopic mobilization of the stomach was performed, helped to visualize the right gastroepiploic artery, which is the main source of blood supply to the formed gastric conduit. The use of ICG technology in 3 patients with a compromised gastrostomy stomach demonstrated the absence of significant microcirculation disorders in the stomach wall. CONCLUSION: The first experience of using fluorescein angiography with ICG in primary esophagoplasty by gastric conduit in patients with malignant tumors of the esophagus demonstrated the safety, simplicity and availability of this technique. An objective assessment of the effectiveness of the application of ICG technology requires the accumulation of experience.

BACKGROUND: Operative performance may affect the internal and external validity of randomized trials. The aim of this study was to review the use of surgical quality assurance mechanisms of published trials on laparoscopic anti-reflux surgery, with the objective to appraise their internal (research quality) and external validity (applicability to the clinical setting). METHODS: Building upon a previous systematic review and network meta-analysis published by the authors, Medline, Embase, AMED, CINAHL, CENTRAL, and OpenGrey databases were searched for randomized control trials comparing different methods of laparoscopic anti-reflux surgery for the management of gastroesophageal disease. Quality assurance in individual studies was appraised using a specified framework addressing surgeon accreditation, procedure standardization, and performance monitoring. RESULTS: In total, 2276 articles were screened to obtain 43 publications reporting 29 randomized controlled trials. Twenty-five out of 43 (58.1%) articles reported the number of participating centers and surgeons involved. Additionally, only 21/43 (48.8%) of articles reported consistent use of a bougie, while 23/43 (53.5%) of articles reported consistent division of the short gastric arteries during fundoplication. Surgical experience and credentials were stated in half of the studies. Standardization of the technique was reported in almost 70% of cases, whereas operative notes or video was submitted in one fourth of the studies. Monitoring of the operative performance during the trial was not documented in most of the trials (62%). CONCLUSION: Surgical quality assurance in randomized trials on laparoscopic anti-reflux surgery is insufficient, which does not allow appraisal of the internal and external validity of this research. With improved reporting, trials assessing the use of laparoscopic anti-reflux surgery will enable surgeons to make informed treatment decisions to enhance patient care in the surgical management of GERD.

Background: Nowadays the question persists whether to choose the endoscopic or surgical method as the first treatment of choice for achalasia. Another debate topic is about the differences between the outcomes of the two approaches of minimally invasive surgical treatment and their feasibility. Material and Methods: This retrospective observational study included 193 patients with achalasia treated between 2008 and 2021. The patients were divided into 2 groups (A and B): 152 with minimally invasive heller myotomy (HM), and 41 with pneumatic dilation (PD). Patients surgically treated were then subdivided into robotic group (RG) and laparoscopic group (LG). Results: The recurrence rate was significantly higher in PD group (Ã?2 = 16.81, DF = 1, p 0.0001), with a success rate of 63,4%, comparing with 92,7% in HM group. No significant difference was obtained between the 2 groups concerning symptom relief on patients successfully treated. The success rate was comparable between the robotic and laparoscopic groups (p = 1). Significant difference was obtained in length of hospital stay between the 2 groups, with a mean of 4.78 +-1.59 days in the RG and, respectively, 5.52 +-2.1 days in the LG (t = 2.40, DF = 124.34, p = 0.0177). Postprocedural esophagitis rates were higher in patients with no fundoplication (6 out of 37 - 16.2%) and in patients treated with pneumatic dilation (4 out of 26 - 15.4%) than in patients with fundoplication (4 out of 46 - 8.5%). Conclusion: The present study indicates that surgery may be a better choice in fit patients for the treatment of achalasia. The procedure has a better success rate, even if the long-term outcomes are comparable in patients successfully treated. The success rate and long-term results were comparable between laparoscopy and robotic surgery.

Treatment of esophageal perforation or rupture is complicated and controversial, especially in advanced cases. In fact, it is generally accepted that this disease must be treated individually according to the location, causes and clinical features of rupture or perforation. A very rare case was admitted to our department, who was injured 5 days ago by high-pressure gas of a running air compressor and resulted in a long-term longitudinal rupture of the thoracic esophagus. Although the patient suffered from empyema and mediastinitis at the same time, and his condition was very serious, the debridement and desquamation of empyema were still implemented, followed by left thoracic esophagectomy and left neck approach esophagogastrostomy in the same period successfully. The patient got a good result finally.

Up to 30% of patients with gastroesophageal reflux disease (GERD) suffer from laryngopharyngeal reflux (LPR) with symptoms, as chronic cough, laryngitis, or asthma. Besides life-style modifications and medical acid suppression, laparoscopic fundoplication is an established treatment option. Treatment-related side effects after laparoscopic fundoplication have to be weighted against LPR symptom control in 30-85% of patients after surgery. Magnetic sphincter augmentation (MSA) is described as an effective alternative to fundoplication for surgical treatment of GERD. However, evidence on the efficacy of MSA in patients with LPR is very limited. Preliminary data on the results of MSA treating LPR symptoms in patients with acid and weakly acid reflux are promising; showing comparable results to laparoscopic fundoplication by providing the potential of decrease side effects.

Magnetic sphincter augmentation (MSA) is an anti-reflux procedure with comparable outcomes to fundoplication, yet its use in patients with larger hiatal or paraesophageal hernias has not been widely reported. This review discusses the history of MSA and how its utilization has evolved from initial Food and Drug Administration (FDA) approval in 2012 for patients with small hernias to its contemporary use in patients with paraesophageal hernias and beyond.

Reoperative surgery following magnetic sphincter augmentation (MSA) is rare. The clinical indications include the removal of MSA for dysphagia, the recurrence of reflux, or the issues of erosion. Diagnostic evaluation follows that of patients with recurrent reflux and dysphagia following surgical fundoplication. Procedures following the complications of MSA can be performed in a minimally invasive fashion, either endoscopically or robotic/laparoscopically, with good clinical outcomes.

BACKGROUND: In patients with paraesophageal hernias (PEH), the course of the esophagus is often altered, which may affect esophageal motility. High-resolution manometry (HRM) is frequently used to evaluate esophageal motor function prior to PEH repair. This study was performed to characterize esophageal motility disorders in patients with PEH as compared to sliding hiatal hernia and to determine how these findings affect operative decision-making. METHODS: Patients referred for HRM to a single institution from 2015 to 2019 were included in a prospectively maintained database. HRM studies were analyzed for the appearance of any esophageal motility disorder using the Chicago classification. PEH patients had confirmation of their diagnosis at the time of surgery, and the type of fundoplication performed was recorded. They were case-matched based on sex, age, and BMI to patients with sliding hiatal hernia who were referred for HRM in the same period. RESULTS: There were 306 patients diagnosed with a PEH who underwent repair. When compared to case-matched sliding hiatal hernia patients, PEH patients had higher rates of ineffective esophageal motility (IEM) (p<.001) and lower rates of absent peristalsis (p=.048). Of those with ineffective motility (n=70), 41 (59%) had a partial or no fundoplication performed during PEH repair. CONCLUSION: PEH patients had higher rates of IEM compared to controls, possibly due to a chronically distorted esophageal lumen. Offering the appropriate operation hinges on understanding the involved anatomy and esophageal function of each individual. HRM is important to obtain preoperatively for optimizing patient and procedure selection in PEH repair.

ABSTRACT: Gastric surface mucosal cells are responsible for the uptake and secretion of 99mTcO4, a feature that has been used in imaging heterotopic gastric mucosa. We used the same principle to look for gastric mucosal viability in this case of pure esophageal atresia admitted for cervical stomal closure after a previous isoperistaltic gastric tube (IGT) replacement procedure. 99mTcO4 scintigraphy was done after encountering a failure to maneuver the esophagoscope through the IGT. The study was helpful in assessing the loss of gastric mucosal viability in an intervening segment of the IGT.

In veterinary clinics, esophageal reconstruction is essential in many clinical situations. In this study, two autografts, the tunica vaginalis (TV) and the buccal mucosa (BM), were proposed to reconstruct a semi-circumferential cervical esophageal defect in dogs. This study aimed to verify whether these two grafts could successfully patch esophageal defects. Twelve male mongrel dogs were divided into two groups. Following cervical esophagoplasty, the defective area was patched with either a TV or a BM graft. Comprehensive clinical, serum biochemical, and histological analyses were performed to evaluate the two grafts. Throughout the study (120 days), the dogs survived the procedure well with minor complications. The lumen of the patched areas was covered with mucosa, with slight scar retraction. Compared with that of the natural esophagus, the average relative luminal diameter was not significantly decreased. Importantly, the measured cortisol and inflammatory marker levels returned to the preoperative levels after 14 days. Although histological examination revealed that both grafts repaired the esophageal defect with complete re-epithelialization, the BM graft showed a histological structure similar to that of the natural esophagus. Both grafts effectively repaired the esophageal defect with minor complications; therefore, both are recommended as promising low-cost clinical alternatives for cervical esophagoplasty in dogs.
