Radial Forearm Flap for Esophageal Perforation After Anterior Cervical Hardware Removal: Surgical Technique and Case Report.

CASE: A 51-year-old woman, who had previously undergone C5-C7 anterior cervical discectomy and fusion, presented with symptomatic hardware failure and subsequently underwent instrumentation removal. Her postoperative course was complicated by an esophageal perforation. Despite initial repair using a rotational flap, the leak persisted, prompting esophageal reconstruction with a radial forearm free flap (RFFF). CONCLUSION: Persistent esophageal perforation is exceedingly rare and difficult to treat. This report discusses the surgical technique for RFFF, an excellent option for revising failed sternocleidomastoid rotational flaps. The decision between rotational repair and free flap reconstruction depends on factors such as defect size, vascularization, wound condition, and donor site morbidity.

Initial management and outcomes of nonmalignant esophageal perforations: A Nationwide Inpatient Sample analysis.

BACKGROUND: Management of esophageal perforation includes open surgery, minimally invasive surgery, and endoscopic stent placement. This study analyzed initial treatment and the associated short-term outcomes. METHODS: A retrospective study using the National Inpatient Sample between October 2015 and December 2019 identified adults >18 years with esophageal perforation undergoing an initial nonelective esophageal procedure categorized into either open surgery, minimally invasive surgery, or endoscopic stent placement. Patients with esophageal cancer were excluded. Baseline characteristics and the van Walraven-weighted Elixhauser Comorbidity Index were identified. Outcomes included in-hospital mortality and postintervention complications. Univariable and multivariable Cox regression was used to compare in-hospital survival. RESULTS: In total, 3,345 patients met inclusion criteria: the median age was 62 years (interquartile range 50-72 years), and 1,310 (39%) were female. Open procedure was pursued in 2,650 (79%), minimally invasive surgery in 310 (9%), and endoscopic stent placement in 385 (12%) with no differences in van Walraven-weighted Elixhauser Comorbidity Index or mortality. Patients who underwent minimally invasive surgery had a greater proportion of gastrointestinal complications (P = .006); otherwise, there were no differences in postintervention complications. In total, 380 (11%) patients died and were significantly older, with greater van Walraven-weighted Elixhauser Comorbidity Index, and had more postintervention complications. Univariable Cox regression identified age (hazard ratio 1.95, P < .001), van Walraven-weighted Elixhauser Comorbidity Index (hazard ratio 1.06, P < .001), stent placement (hazard ratio 1.93, P = .045), and transfer from a health facility (HR 2.40, P = .049) as associated with decreased in-hospital survival. Multivariable Cox regression revealed age (hazard ratio 1.041, P < .001) and van Walraven-weighted Elixhauser comorbidity index (hazard ratio 1.055, P < .001) were associated with decreased in-hospital survival. CONCLUSION: Patients with esophageal perforation had an 11% in-hospital mortality rate and significant associated complications regardless of intervention. Increasing age and comorbidities are associated with poorer in-hospital survival.

Multi-modality management of defects in the gastrointestinal tract: Where the endoscope meets the scalpel: Endoscopic vacuum therapy in the upper gastrointestinal tract.

BACKGROUND: Transmural defects in the upper gastrointestinal (GI) tract, such as anastomotic leakage and oesophageal perforations, are associated with significant morbidity and mortality risks. Endoscopic vacuum therapy (EVT) is an efficient and safe treatment option for these patients. With the growing use of EVT in the upper GI tract, it is important to share expertise on the topic. AIM: This review explores the emerging role of endoscopic vacuum therapy (EVT) as treatment for transmural defects in the upper GI tract. An overview of the mechanism and procedures, outcomes in current literature and challenges of implementation and application are discussed. CONCLUSION: EVT exhibits great efficacy and safety for the treatment of transmural defects in the upper GI tract. Current use of EVT is mostly experience-based, emphasizing the importance of sharing expertise and performing research to unlock its full potential.

Endoscopic full-thickness resection of a large gastric schwannoma and iatrogenic cervical esophageal perforations: A case report.

INTRODUCTION: Gastrointestinal schwannomas are most commonly found in the stomach. Owing to their nonspecific clinical and endoscopic presentations, distinguishing gastric schwannomas (GS) from other gastric submucosal tumors based on typical symptoms and endoscopic features is challenging. Endoscopic full-thickness resection (EFTR) is safe and effective for GS management; however, no standard method exists for the extraction of large gastric specimens after endoscopic treatment. CASE PRESENTATION: We report the case of a 72-year-old Chinese woman who presented with abdominal distension. DIAGNOSIS, INTERVENTIONS, AND OUTCOMES: Gastroscopy revealed a submucosal bulge on the anterior wall of the lower stomach near the greater curvature. Endoscopic ultrasonography and computed tomography suggested a stromal tumor. The patient underwent EFTR of the stomach, and the tumor was successfully removed. The surgical specimen, with a long-axis diameter of approximately 5.5 cm in vitro, was extracted using a snare. Subsequent endoscopic examination revealed longitudinal, full-thickness perforations > 2 cm at the esophageal entrance. Over 10 metal clips were used to seal the mucosa, and a gastrointestinal decompression tube was placed. Follow-up radiography performed at 1 week postoperatively revealed an esophageal mediastinal fistula, which required subsequent endoscopic intervention to close the fistula using metal clips. The patient showed improvement and was discharged at 3 weeks postoperatively. Follow-up esophageal radiography revealed no abnormalities. Postoperative immunohistochemical analysis indicated CD34 (-), CD117 (-), DOG-1 (-), Ki67 (1%), S-100 (+), SDHB (+), SOX-10 (+), and Desmin (-), confirming the diagnosis of GS. Three months postoperatively, gastroscopy showed that the esophageal perforation healed well, a white ulcer scar had formed locally, metal clips were found in the stomach body, and no recurrence was found. CONCLUSION: EFTR is effective for removing giant schwannomas, although the extraction of large specimens may result in iatrogenic cervical esophageal perforations. Perforations > 2 cm can be managed using endoscopic metal clip closure.

Surgical repair of an aortoesophageal fistula after salvage thoracic endovascular aortic repair: a case report.

BACKGROUND: An aortoesophageal fistula can prove to be fatal. Salvage thoracic endovascular aortic repair as a bridging therapy and radical surgery with thoracotomy should be considered while treating aortoesophageal fistula without spontaneous closure. Moreover, it is essential to select a technique that reduces the risk of reinfection. Here we report a rare case of a ruptured thoracic aortic aneurysm related to esophageal perforation by a fish bone that led to massive hematemesis and shock, and the surgical treatment of an aortoesophageal fistula that developed after salvage thoracic endovascular aortic repair. CASE PRESENTATION: A 70-year-old Japanese female patient was admitted with hematemesis, thoracic pain, and shock related to esophageal perforation of a ruptured descending aortic aneurysm caused by fish bone aspiration and esophageal perforation 1 month previously. An emergency thoracic endovascular aortic repair was performed. Postoperatively, an aortoesophageal fistula that remained open and a food intake-related increase in the inflammatory response was noted. Radical blood-vessel prosthesis implantation and fistula closure were performed. The patient's postoperative course was favorable and the patient was discharged 22 days after the blood vessel prosthesis implantation. CONCLUSION: Such a case of rupture of a descending aortic aneurysm related to perforation by a fish bone and an aortoesophageal fistula is considerably rare. Thus, we report the therapeutic strategy of this particular case and review the relevant literature.

Surgical treatment of Boerhaave syndrome in the past, present and future: updated results of a specialised surgical unit.

INTRODUCTION: Boerhaave syndrome is a rare clinical entity associated with high rates of morbidity and mortality. Early recognition of the symptoms, and identification of the site and extension of the injury are key in improving the prognosis. METHODS: This study presents data on the mortality, morbidity and length of hospital stay in patients diagnosed with Boerhaave syndrome. The data were retrieved from a prospectively collected database in a single surgical unit between 2012 and 2022. The study makes a comparison with the surgical outcomes of the previous decade. RESULTS: Some 33 patients were diagnosed with Boerhaave syndrome and were treated surgically between 2012 and 2022 in a specialist upper gastrointestinal surgical unit. All patients underwent standard surgical repair (in-theatre diagnostic endoscopy, T-tube placement through thoracotomy and feeding jejunostomy through laparotomy). The mean size of the defects in the oesophageal lumen was 3.3cm. Delayed presentation was noted for 13 patients (39%); 8 patients (24%) died in hospital, and 19 patients (58%) developed postoperative complications. Mortality was similar to the rate recorded for the 20 patients from the previous decade (24% vs 20%, respectively). The mean length of hospital stay was 41 days, and was comparable to the 35.7 days reported between 1997 and 2011. CONCLUSIONS: Early and aggressive management of spontaneous oesophageal rupture ameliorates the postoperative recovery and prognosis. The surgical results of our unit were found comparable to the previous decade in the population of patients who were treated surgically.

Novel use of dynamic MR hydrography to rule out esophageal perforation post atrial fibrillation ablation in a patient with anaphylaxis to gadolinium.

Esophageal thermal injury is one of the most devastating complications of atrial radiofrequency ablation, and its diagnosis can be challenging. In this report, we highlight the novel use of free water as a contrast material to better visualize the esophageal lumen in a patient with anaphylaxis to Iodinated contrast media and Gadolinium who recently underwent atrial fibrillation ablation. This becomes particularly handy in patients with contrast allergy, and further emphasizes the role of multimodality imaging.

Endoscopic self-expandable metal stent versus endoscopy vacuum therapy for traumatic esophageal perforations: a retrospective cohort study.

BACKGROUND: Traumatic esophageal perforations (TEP) are a grave medical condition and require immediate intervention. Techniques such as Esophageal Self-Expandable Metal Stent (E-SEMS) and Endoscopic Vacuum Therapy (EVT) show promise in reducing tissue damage and controlling esophageal leakage. The present study aims to compare the application of EVT to E-SEMS placement in TEP. METHODS: Retrospective cohort study valuated 30 patients with TEP. The E-SEMS and EVT groups were assessed for time of hospitalization, treatment duration, costs, and clinical outcome. RESULTS: Patients treated with EVT (24.4 ± 13.2) demonstrated significantly shorter treatment duration (p < 0.005) compared to the group treated with E-SEMS (45.8 ± 12.9) and patients submitted to E-SEMS demonstrated a significant reduction (p = 0.02) in the time of hospitalization compared to the EVT (34 ± 2 vs 82 ± 5 days). Both groups demonstrated a satisfactory discharge rate (E-SEMS 93.7% vs EVT 71.4%) but did not show statistically significant difference (p = 0.3155). E-SEMS treatment had a lower mean cost than EVT (p < 0.05). Descriptive statistics were utilized, arranged in table form, where frequencies, percentages, mean, median, and standard deviation of the study variables were calculated and counted. The Fisher's Exact Test was used to evaluate the relationship between two categorical variables. To evaluate differences between means and central points, the parametric t-test was utilized. Comparisons with p value up to 0.05 were considered significant. CONCLUSION: E-SEMS showed a shorter time of hospitalization, but a longer duration of treatment compared to EVT. The placement of E-SEMS and EVT had the same clinical outcome. Treatment with E-SEMS had a lower cost compared with EVT.

Robotic surgery in the management of synchronous esophageal and gastric perforation after endoscopic dilation.

Upper gastrointestinal perforation is a feared complication of diagnostic and therapeutic endoscopy, with an incidence of perforation between 0.3% and 5%. Even though is rare, the mortality rate can be as high as 40%. Currently, there is no consensus on the best therapeutic strategy and it usually depends on patient stability, the extent of perforation, time to diagnosis, surgeon experience and available resourcesWe present a case of a patient who presented to our institution to undergo an ambulatory oesophageal dilation. After dilation, the patient developed two full-thickness gastric perforations and a full-thickness oesophageal perforation without haemodynamic instability. All perforations were diagnosed and treated with a combination of intraoperative endoscopy and robotic surgery with excellent outcomes.We demonstrate that a robotic approach combined with intraoperative diagnostic endoscopy is a safe and feasible treatment option for esophageal and gastric perforations in a stable patient without large extraluminal contamination.

[Endoscopic vacuum therapy in minimally invasive treatment of esophageal perforations]. / Effektivnost' endoskopicheskoi vakuumnoi terapii v kompleksnom minimal'no invazivnom lechenii perforatsii pishchevoda.

OBJECTIVE: To compare the results of endoscopic vacuum therapy (EVT) and open surgery for esophageal perforations. MATERIAL AND METHODS: The study included 60 patients with esophageal perforations between 2010 and 2022. The main group included 29 patients who underwent minimally invasive treatment with EVT, the control group - 31 patients after open surgical interventions. RESULTS: Pneumonia occurred in 21 (72%) and 14 (45%) patients (p=0.04), esophageal stenosis within the perforation zone - in 4 (13.8%) and 1 (3.2%) patient, respectively (p=0.188). Chronic esophageal fistulas were significantly more common in the control group (6 (20.7%) versus 15 (48.4%) patients, p=0.032). The overall duration of treatment (median) among survivors was significantly shorter in the main group: 33 (23; 48) versus 71.5 (59; 93.7) days (p=0.5). However, length of ICU-stay was slightly higher (11 (6; 16) versus 8.5 (5; 12.75) days, p=0.32). Mortality rate was 13.8% (n=4) and 29% (n=9), respectively (p=0.213). Minimally invasive technologies decreased the risk of fatal outcome by 10 times (OR 10.123, 95% CI 1.491-124.97, p=0.035) compared to traditional surgery. CONCLUSION: EVT in complex minimally invasive treatment of patients with mechanical esophageal injuries is an effective method significantly reducing mortality and duration of inpatient treatment compared to traditional surgical approach.

Outcome after stent and endoscopic vacuum therapy-based treatment for postemetic esophageal rupture.

OBJECTIVES: Extent of surgical repair of spontaneous esophageal effort rupture (Boerhaave syndrome) has gradually decreased by the emergence of minimal invasive treatment based on endoscopic stent sealing of the perforation. However, for this diagnosis, use of endoscopic vacuum therapy (EVT) is still in its beginning. We present our results after 7-years with both stent and/or EVT-based treatment. MATERIALS AND METHODS: 17 consecutive patients with Boerhaave syndrome from June 2015 to May 2022 were retrospectively registered in a database. The perforation was sealed by stent and/or EVT, and gastric effluent was drained transthoracically by a chest tube or pigtail catheter. Eight out of 14 patients responded to questions on fatigue and dysphagia (Ogilvie's score). RESULTS: Seventeen patients aged median 67 years (range 34-88), had a primary hospital stay of 38 days (7-68). Ninety-day mortality was 6% (n = 1). Perforations were sealed with stent (n = 10), EVT (n = 3) or stent and EVT (n = 4). One patient (6%) needed laparoscopic lavage and transhiatal drainage. Eight patients (47%) were re-stented due to persistent leakage (n = 4) and stent migration (n = 4). Fifteen patients (88%) had complications, including multi-organ failure (n = 9), pleural empyema (n = 8) and esophageal stricture (n = 3). The perforations healed. After 35.5 months (range 2-62) fourteen patients were alive. Eight that responded had no dysphagia and total fatigue score comparable to an age-matched reference population. CONCLUSION: Mortality rate was low after initial stent and EVT-based treatment of Boerhaave syndrome, combined with adequate transthoracic drainage of gastric effluent. Patients required repeated minimal invasive procedures, but with no apparent negative effect on functional outcome.

Transgastric drainage of the perforated esophagus: our experiences over 10 years.

We first described the technique of transgastric drainage of esophageal injuries in 2008. The method establishes vacuum drainage of the lumen of the esophagus, while maintaining patency, effectively exteriorizing the perforation to allow healing. We summarize this technique and present our experiences from the largest published series of patients. Our unit has treated selected esophageal injuries with transgastric drainage for 10 years. Indications include perforations not amenable to primary repair and treatment failure following prior surgical intervention. A 36 French silastic chest drain is pulled through the abdominal and stomach wall and introduced into the esophagus so that it crosses the perforation. Gastropexy is performed. Mediastinal decontamination and drainage are performed as needed. Continuous suction of -10 cm water is applied. Leak resolution is assessed with weekly water-soluble swallows. For this retrospective observational study, we analyzed data for patients with esophageal perforation, between 2012 and 2022. Inpatient mortality and time to leak resolution were set as primary and secondary outcomes. Esophageal perforations were treated with transgastric drain in 35 patients, of whom 68% (n = 24) were men. Median age was 67 (26-84). Spontaneous perforations accounted for 60% (n = 21), 31% (n = 11) were iatrogenic and 6% (n = 2) were ischemic. Inpatient and 30-day mortality was 14% (n = 5). Among successful treatments, the median length to resolution of leak on imaging was 34.5 days (6-80). Transgastric drainage can successfully treat esophageal perforations, where primary repair is not feasible. The mortality rate of 14% and reduced morbidity compares favorably with other traditional methods of management for esophageal perforation.

Robotic Heller's cardiomyotomy for achalasia: early outcomes for a high-volume UK centre.

INTRODUCTION: Heller's cardiomyotomy (HCM) is the gold standard treatment for achalasia. Laparoscopic HCM has been shown to be effective with low rates of symptom recurrence, though oesophageal mucosal perforation rates remain high. The aim of this prospective case series is to assess the short-term complication rates and perioperative outcomes for the first cohort of patients undergoing robotic-assisted HCM for achalasia in a single high-volume UK centre. METHODS: Data were collected from a prospective cohort of patients who underwent robotic HCM at a single high-volume UK centre. Outcomes were assessed using the Eckhard score, which was calculated after their routine postoperative clinic appointments. RESULTS: Thirteen patients underwent robotic HCM during the study period; this is the second largest reported case series in the European literature. There were no intraoperative oesophageal perforations. Six patients were discharged as day cases, six patients were discharged on the first postoperative day and one patient's hospital stay was two nights. There was a single perioperative complication of urinary retention. All patients reported improvement of symptoms following their operation, and all had a postoperative Eckhard score of less than 3, indicating their achalasia was in remission. CONCLUSIONS: This cohort has demonstrated that robotic HCM has an exceptional safety profile and results in high levels of symptom resolution, even early in the learning curve. The robotic approach may be superior to laparoscopy as it allows more precise identification and dissection of the oesophageal muscle fibres, which likely reduces the risk of inadvertent mucosal damage or incomplete myotomy.

Esophageal injury, perforation, and fistula formation following atrial fibrillation ablation.

BACKGROUND: Esophageal perforation and fistula formation are rare but serious complications following atrial fibrillation ablation. In this review article, we outline the incidence, pathophysiology, predictors, and preventative strategies of this dreaded complication. METHODS: We conducted an electronic search in 10 databases/electronic search engines to access relevant publications. All articles reporting complications following atrial fibrillation ablation, including esophageal injury and fistula formation, were included for systematic review. RESULTS: A total of 130 manuscripts were identified for the final review process. The overall incidence of esophageal injury following atrial fibrillation ablation was significantly higher with thermal ablation modalities (radiofrequency 5-40%, cryoballoon 3-25%, high-intensity focused ultrasound < 10%) as opposed to non-thermal ablation modalities (no cases reported to date). The incidence of esophageal perforation and fistula formation with the use of thermal ablation modalities is estimated to occur in less than 0.25% of all atrial fibrillation ablation procedures. The use of luminal esophageal temperature monitoring probe and mechanical esophageal deviation showed protective effect toward reducing the incidence of this complication. The prognosis is very poor for patients who develop atrioesophageal fistula, and the condition is rapidly fatal without surgical intervention. CONCLUSIONS: Esophageal perforation and fistula formation following atrial fibrillation ablation are rare complications with poor prognosis. Various strategies have been proposed to protect the esophagus and reduce the incidence of this fearful complication. Pulsed field ablation is a promising new ablation technology that may be the future answer toward reducing the incidence of esophageal complications.

Replogle Modified Endoscopic Vacuum-Assisted Closure (EVAC) Therapy: A New Strategy to Treat Anastomotic Leakage and Esophageal Perforation.

BACKGROUND: Anastomotic leakage (AL) and esophageal perforation are life-threatening complications following surgery or endoscopic dilations. "Replogle modified EVAC therapy" consists of placing a Replogle tube directly into the lumen or within an abscess cavity and remove by suction all intra-cavity fluids and secretion with a continuous low-pressure suction, promoting granulation tissue proliferation, thereby gradually decreasing the cavity size. The aim of our study was to evaluate the technical feasibility, safety, and efficacy of this technique in pediatric patients. METHODS: A retrospective review charts of consecutive pediatric patients that were treated with "Replogle modified EVAC therapy" at our pediatric referral center between 2013 and 2022 was conducted. The clinical, endoscopic, radiological, and surgical information and data of patients were collected and revised as well as their follow-up and outcomes. RESULTS: Ten patients (6/10 male; mean age: 7.8 y.o., range: 1.1-18 y.o.) were treated using the "Replogle modified EVAC therapy". Four out of ten patients developed esophageal perforations after endoscopic procedures. Six out of the ten enrolled patients had AL complications after surgical operations. All patients were successfully treated. There were no technical failures or complications with device placement. Mean treatment duration was 16 days (range 7-41 days). No additional treatment was needed for complete leak resolution. CONCLUSIONS: "Replogle modified EVAC therapy" represents a promising and mini-invasive method to treat esophageal perforations and post-surgical leak in the paediatric age group. In our experience, the use of this technique was safe, effective, and particularly well suited also in complex paediatric patients. LEVEL OF EVIDENCE: IV.
