Surgical Management of Non-Malignant Esophageal Perforations: A Single-Center Analysis Over a 15-Year Period.

PURPOSE: Esophageal perforations are associated with high morbidity and mortality. Different nonoperative and operative treatment options have been proposed. This study focuses on the impact of different surgical treatments in nonmalignant esophageal perforations and tries to identify predictors of mortality in a single tertiary center over a 15-year period. METHODS: From 2002 to 2017, patients with surgically managed esophageal perforation were identified from our database. Patients with esophageal malignancies were excluded. Etiology, clinical data, treatment, and outcome were analyzed. A multivariate logistic regression analysis was performed to investigate the impact on mortality. RESULTS: A total of 72 patients were identified. The majority of perforations were iatrogenic (54.2%) followed by Boerhaave's syndrome (23.6%). Most ruptures were found in the distal third of the esophagus (59.7%) measuring <3 cm (61.1%). Patients were treated with exploration and drainage (8.3%), primary suture and patch reinforcement (36.1%), resection and restoration of continuity (25.0%), or resection without restoration of continuity (30.6%). Delayed therapy significantly correlated with sepsis (p < 0.0001) and mortality (p = 0.032). A correlation between an increasing perforation length with sepsis (p = 0.012) was observed. A higher Perforation Severity Score (PSS; OR 4.430; 95% CI 1.143-17.174; p = 0.031) and a higher American Society of Anesthesiologists (ASA) score (OR 2.923; 95% CI 1.011-8.448; p = 0.048) were associated with mortality in multivariate analysis. CONCLUSION: Esophageal perforations are associated with high mortality, and larger ruptures are associated with worse outcome. Rapid diagnosis and treatment are crucial for patient survival. Hence, PSS and ASA score help to identify high-risk patients. The advantage of surgical management lies in the rapid control of the septic focus in an already critically ill patient. Though, the kind of surgical technique needs to be adjusted to the individual situation.

Poorly Differentiated Biliary Adenocarcinoma Leading to Boerhaave syndrome: A Case Report and Review of the Literature.

Boerhaave syndrome is a transmural disruption of the esophagus, due to an increase in esophageal pressure and is associated with high morbidity and mortality. There are cases reported secondary to bowel obstructions such as incarcerated hernias and gallstone ileus. Here, we describe an unusual autopsy case of Boerhaave syndrome, due to bowel obstruction secondary to biliary adenocarcinoma, which has never been reported in the literature. The patient was an 87-year old male presenting with severe chest and epigastric pain. Computed tomography showed fluid-filled esophagus, gastric distention and an ill-defined mass within the liver. Patient underwent esophagogastroduodenoscopy, which revealed esophageal rupture. Patient expired within 20 hours of admission. On autopsy, the decedent was found to have an esophageal perforation and an inferior hepatic mass, which morphologically and immunohistochemically was consistent with a biliary adenocarcinoma.

Sudden Unexpected Death Due to Left Subclavian Artery-esophageal Fistula Caused by Fish Bone.

A 53-year-old woman was admitted to the hospital due to unexpected dizziness and died the following morning. To investigate the cause of death, a forensic autopsy along with histological examination was performed 3 days after her death. The major findings of the autopsy were that a fish bone had pierced the left subclavian artery after perforating the esophagus with 680 mL of blood in the stomach and bloody and tarry contents were present in the intestines, and the cause of death was confirmed to be subsequent hemorrhagic shock. Unfortunately, none of her family realized that she had eaten a fish 4 days before the tragedy until the fish bone was found. The present case is rare and instructive. The histopathological findings of left subclavian artery-esophageal fistula induced by a fish bone can be used as a reference in forensic practice.

Temporary insertion of a covered self-expandable metal stent to treat esophageal perforation due to endoscopic submucosal dissection.

There are no previous reports of esophageal perforation due to endoscopic submucosal dissection developing into pyothorax. We herein describe a case of esophageal healing following perforation in a 60-year-old woman undergoing esophageal endoscopic submucosal dissection. Post-procedural computed tomography revealed pyothorax in the right thoracic cavity, compressing the right lung. The pyothorax did not improve despite treatment with thoracic drainage because the esophageal lumen was connected to the right thoracic cavity. In order to close the site of esophageal perforation, we inserted a covered self-expandable metal stent. The affected site subsequently healed without complications, allowing the drainage tube and stent to be removed.

Multiple magnetic gastrointestinal foreign bodies in a dog.

CASE DESCRIPTION: A 3-year-old castrated male Yorkshire Terrier was referred because of a 3-day history of vomiting, hyporexia, and lethargy after suspected ingestion of magnetic desk toys. Multiple metallic gastric foreign bodies were visible on radiographic views obtained 24 hours previously by the referring veterinarian. CLINICAL FINDINGS: On physical examination of the dog, findings included moderate dyspnea, signs of pain in the cranial portion of the abdomen, hypothermia, and tachycardia. Repeated radiography revealed moderate pleural effusion and the presence of several round metallic foreign bodies in a linear ring formation in the distal aspect of the esophagus and gastric cardia. TREATMENT AND OUTCOME: Endoscopy was performed, at which time the dog became increasingly dyspneic, tachycardic, and hypotensive. Thoracocentesis was performed, and a large volume of septic exudate was removed from the left hemithorax. Exploratory surgery of the thoracic and abdominal cavities was performed, during which the magnetic foreign bodies were removed and esophageal and gastric perforations were debrided and closed. The dog died following acute cardiac arrest 48 hours after surgery. CLINICAL RELEVANCE: Ingestion of multiple magnetic foreign bodies carries a high risk of gastrointestinal tract perforation, volvulus, and obstruction. Immediate surgical intervention is recommended in such cases and would have likely improved the outcome for the dog of this report.

Aorto-oesophageal fistula and aortic pseudoaneurysm caused by a swallowed fish bone.

We describe a rare case of aorto-oesophageal fistula and aortic pseudoaneurysm in a middle-aged man, who presented with chest pain and haematemesis 1 week after swallowing a fish bone. Oesophagogastroduodenoscopy and computed tomographic angiography findings were consistent with oesophageal perforation, proximal descending aortic pseudoaneurysm, and aorto-oesophageal fistula. Thoracic endovascular aortic repair was performed. The patient died from severe mediastinal sepsis. Early surgical intervention and broad-spectrum antibiotic therapy are crucial in preventing life-threatening mediastinal infection.

Esophageal perforation related to anterior cervical spinal surgery.

Esophageal perforation is an uncommon but potentially fatal complication of anterior cervical spinal surgery. This study aimed to investigate the diagnosis and treatment of cervical esophageal perforation related to spinal surgery. Among 1097 consecutive cases of anterior cervical spinal surgery that were managed at our institution over a 20 year period, five patients with esophageal perforation were identified. We performed a retrospective review of the diagnoses and treatment of esophageal perforation in these five patients as well as another patient who was transferred from another hospital. The esophageal perforations in all six patients were recognized during the early postoperative period. All patients presented with neck pain, dysphagia, odynophagia, coughing, fever and incision swelling and drainage. Diagnosis was confirmed by one or several of the following methods: contrast swallow study; endoscopy; cervical radiographs; or oral methylene blue. Nasogastric tube, intravenous antibiotics, enteral and parenteral nutrition, and open drainage were conducted in all patients. The wound was debrided in three patients, while two had implant removal and primary suture of the perforation. Five patients had a good recovery with healing of the esophagus, while one patient died due to severe pneumonia. The early diagnosis of esophageal perforation related to cervical spinal surgery relies on clinical suspicion and efficient investigation. The selection of appropriate treatment options, which include esophageal rest, antibiotic administration, nutrition support, wound debridement, open drainage, and surgical repair, largely depends on when the perforation is recognized. Early diagnosis and prompt management of this complication are likely to result in a good clinical outcome.

Cervical oesophageal and hypopharyngeal perforations after anterior cervical spine surgery salvaged with regional and free flaps.

BACKGROUND AND PURPOSE: The object of the study was to present our own experience in the management of cervical oesophageal and hypopharyngeal perforations after anterior cervical spine surgery. MATERIAL AND METHODS: The study group consists of 5 patients treated in Department of Otolaryngology Poznan University of Medical Sciences in 2009-2011. Different materials and techniques were used to repair the perforations: infrahyoid flap, primary sutures supported by sternocleidomastoid muscle flap, thigh flap and forearm flap in two cases. RESULTS: Four out of 5 patients were referred to our department in a poor general condition, with infected neck fistulas, three patients after prolonged conservative treatment, and three patients after initial attempts to repair the perforation outside our institution. One-stage reconstructive surgery was successful in three cases, while in two others secondary interventions were necessary. Total hospital stay ranged in the analysed group from 23 to 191 days, hospital stay in our department from 1 to 62 days, hospital stay from the final procedure from 18 to 26 days. Swallowing function was within normal limits in all cases 12-14 days after the surgery. CONCLUSIONS: The authors' experience shows that in long-lasting and infected cervical oesophageal and hypopharyngeal perforations following anterior cervical spine surgery distant flaps should be primarily used as a source of a well-vascularized and unchanged tissue. It seems to be crucial to repair the perforations immediately after the first symptoms appear - such an approach significantly reduces total hospital stay and improves the prognosis.

Type B aortic dissection resulting in acute esophageal necrosis.

In the present article, we report a case in which acute esophageal necrosis (AEN) of the intrathoracic esophagus was caused by extensive thrombosis in the false lumen of an aortic dissection, thereby occluding the blood flow to the intercostal arteries and thus the esophagus. According to the previously published data, AEN after aortic dissection is very rare and usually fatal. Besides esophageal ischemia secondary to arterial occlusion, direct extrinsic compression of the arteriovenous network surrounding the esophagus, caused by the traumatic pathology of the aorta, by extensive extravasation may also cause AEN. AEN is most commonly confirmed by esophagoscopy, typically showing a black, diffusely necrotic, and ulcerated esophageal mucosa.

[Boerhaave's syndrome and pleural tuberculosis]. / Syndrome de Boerhaave et tuberculose pleurale.

INTRODUCTION: Boerhaave's syndrome is a rare condition involving spontaneous rupture of the oesophagus. The diagnosis is difficult and the prognosis depends on early diagnosis and treatment. CASE REPORT: We report a case of spontaneous rupture of the oesophagus in a 70-year-old woman where the diagnosis was delayed. Initial treatment comprised dual antibiotic therapy and feeding via a jejunostomy. Three months later, direct suture of the oesophagus was performed successfully. A routine pleural biopsy performed during the surgery revealed pleural tuberculosis. Antituberculous treatment was given for 6 months with good progress after 16 months follow up. CONCLUSION: Boerhaave's syndrome is a rare condition, the diagnosis of which remains difficult. The prognosis is related essentially to the speed of diagnosis. The treatment is always surgical within the framework of appropriate medical management (intensive care, antibiotic therapy). There should be a systematic search for associated pathology.

[Treatment for esophageal perforations: analysis of 11 cases]. / Özofagus perforasyonlarinda tedavi: On bir olgunun analizi.

BACKGROUND: We present 11 cases with esophageal perforations who were treated in our department, with the intent of underlining the importance of surgical intervention. METHODS: We retrospectively analyzed 11 cases of esophageal perforation who were treated from 2005 to 2010. The cases diagnosed within the first 24 hours were regarded as early diagnoses; those diagnosed later than this period were regarded as late diagnoses. RESULTS: The mean age of the patients was 45.8 years. Following the perforation, 3 of the patients had early diagnoses and the others had late diagnoses. Of the 3 cases with early diagnosis, all had primary repair; of the late diagnosis cases, 4 had primary repair, 2 had colonic interposition, 1 had stent implantation, and 1 received medical treatment. All the cases with late diagnoses underwent drainage. The 3 cases who received early treatment recovered without complications. Of the other 8 cases, 1 had leakage from the anastomosis and 1 developed a fistula. Two (18.1%) of our patients died. CONCLUSION: Treatments performed before the development of mediastinitis are lifesaving in esophageal perforation patients. We think that surgical treatment performed within the first 72 hours that includes primary repair would yield favorable results.

Clip closure versus endoscopic suturing versus thoracoscopic repair of an iatrogenic esophageal perforation: a randomized, comparative, long-term survival study in a porcine model (with videos).

BACKGROUND: Esophageal full-thickness wall repair is an important but unsolved issue in endoscopy. It is unknown how well endoscopic clip closure (ECC) and endoscopic closure with suturing (ECS) perform compared with the criterion standard of thoracoscopic closure (TC). OBJECTIVE: Comparison of technical success, feasibility, long-term patency, complications, and histological quality of the different closure techniques (ECC, ECS, TC) for esophageal perforations. DESIGN: Comparative animal study. SETTING: Approved animal facility. SUBJECTS: Eighteen pigs. INTERVENTIONS: Eighteen pigs were randomized, 6 each into 3 groups (ECC, ECS, TC). After endoscopic wall incision and mediastinoscopy, closure was performed by using 1 of the 3 techniques. After 8 to 12 weeks, pre-euthanasia endoscopic, necropsy, histological, and morphometric analyses were performed. MAIN OUTCOME MEASUREMENT: Long-term survival and histological quality of the repair. RESULTS: The closure of the esophageal incisions was successful in all pigs. On days 2 and 6, 1 animal died of mediastinitis, 1 in the ECS group because of reflux of gastric contents into the mediastinum before the repair and 1 in the TC group because of leakage of the sutured closure (P = 1.0). No strictures were seen on prenecropsy endoscopy. At necropsy, 1 mediastinal abscess was found in an ECS animal (P = 1.0). Minor complications included periesophageal adhesions and reactive lymph nodes in 3 of 6 (ECC group) and 5 of 6 (TC and ECS groups). Histology showed muscle layer defects up to 12 mm in width and 21 mm in length, with a trend toward smaller defect size of width and length in the ECS group of animals. LIMITATIONS: Animal study of limited size. CONCLUSIONS: Overall, ECS and ECC performed similarly to TC. ECS showed the smallest histological defects in the long-term repair.

Rupture of Kommerell diverticulum after total arch replacement.

A 62-year-old man was brought to the emergency room of our hospital because of chest pain. Computed tomography revealed a right aortic arch and an aberrant left subclavian artery with Kommerell diverticulum and acute aortic dissection (Stanford type A). Total arch replacement was performed emergently through a median full sternotomy. A stomach feeding tube was placed postoperatively for the patient to receive nutrition, and esophageal bleeding was observed postoperatively. The patient died because of the bleeding. Autopsy findings showed a communication between the esophagus and Kommerell diverticulum. Rupture of Kommerell diverticulum and perforation of the esophagus were indicated.
