Prophylaxis of complications in operations for cancer of middle and lower thirds of the esophagus

Objective. Improvement of the surgical treatment results in esophageal cancer. Маterials and methods. Results of surgical treatment of 43 patients, having cancer of middle and lower thirds of the esophagus, were analyzed. Lewis operation was performed in 38 patients, and Garlock operation – in 5. Circular suture stapler with second row of a П-like manual sutures was applied in 28 patients. In 15 patients anastomosis was formatted, using hand-sewn two-row suture. The method of anastomosing choice had depended upon local and general factors: the tumor localization, the esophageal wall changes in anastomotic site, degree of the water-electrolyte disorders, the protein balance, concurrent pathology. Prophylaxis of postoperative morbidity consisted of preoperative correction of laboratory indices, treatment of concurrent pathology, choice of the anastomosis formation method, postoperative intensive therapy. Results. Postoperative complications had occurred in 1 (2.3%) patient. Mostly frequent postoperative complication after resection for esophageal cancer constitute insufficiency of esophago-gastric anastomosis, which occurs under impact of general and local factors. General factors: disorders of the blood circulation, caused by cardiac insufficiency, hypoxia due to pulmonary insufficiency, coagulopathy, disorders of the protein and water-electrolyte metabolism. Reduction of influence of general factors on the postoperative morbidity occurrence was achieved using the intensive preoperative preparation conduction. Conclusion. The postoperative morbidity prevention turns effective while its accomplishment on all stages of treatment: during preoperative preparation, intraoperatively and postoperatively.

Endoscopic Ultrasonography in Children with Eosinophilic Esophagitis—A Review

Endoscopic ultrasonography (EUS) is a diagnostic endoscopy of the upper gastrointestinal tract, during which ultrasound of nearby organs is also performed. It is also possible to perform a fine needle aspiration biopsy. Currently, EUS is performed more frequently in adults. Despite some limitations, this diagnostic method is also more and more often performed in pediatric patients. Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus, which also occurs in children, and leads to irreversible fibrosis of the esophagus wall, if left untreated. Traditional methods of diagnosing and monitoring EoE treatment have significant limitations, and the use of EUS and total esophageal wall thickness (TWT) assessment may bring measurable benefits. Several studies have shown an increased thickening of TWT in EoE in children compared to pediatric patients with gastroesophageal reflux disease, and a decrease in TWT in adults who responded to EoE treatment. These results suggest that EUS and TWT measurement may become an important test in diagnostics, monitoring the effectiveness of therapy, assessing disease progression, and in individualizing the method and duration of EoE treatment also in children.

A rare form of intoxication: acute methyl ethyl ketone peroxide poisoning

We report two suicidal cases of acute methyl ethyl ketone peroxide (MEKP) poisoning. A woman in her late 60s suffered from oral mucosal erosion, functional impairment of the heart, liver and other organs, pulmonary inflammation, elevated inflammatory markers, pleural effusion, hypoproteinemia and metabolic acidosis after oral administration of approximately 50 mL of MEKP. After admission, the patient was administered hemoperfusion four times, 8 mg of betamethasone for 6 days and symptomatic support. Hemoperfusion had an obvious effect on the treatment of oral MEKP poisoning. After discharge, the patient developed progressive dysphagia and secondary esophageal stenosis. Supplementary feeding was administered with a gastrostomy tube after the patient was completely unable to eat. A man in his mid-40s developed oropharyngeal mucosal erosion, bronchitis and esophageal wall thickening after oral administration of 40 ml MEKP. After receiving total gastrointestinal dispersal, 80 mg of methylprednisolone was administered for 7 days, and symptomatic supportive treatment was provided. Slight dysphagia was observed after discharge, and there was no major effect on the quality of life. Patients with acute oral MEKP poisoning should be followed up regularly to observe its long-term effects on digestive tract corrosion and stenosis.

Improvement of surgical methods for the treatment of spontaneous rupture of the esophagus ­complicated by purulent mediastinitis

Aim. To improve surgical treatment outcomes of patients with spontaneous rupture of the esophagus complicated by purulent mediastinitis. Methods. Over the past 30 years, we have experience in the surgical treatment of 31 patients with spontaneous rupture of the esophagus complicated by purulent mediastinitis. Depending on the tactics and techniques of surgical treatment, we identified two groups of patients. The first group (n=8) consisted of patients operated with conventional techniques: thoracotomy, transpleural mediastinotomy according to Dobromyslov, suturing of the esophagus with drainage of the mediastinum and pleural cavities, blind mediastinal drainage. The second group (n=23) consisted of patients treated with programmed re-thoracotomy. Re-thoracotomy was performed along with the postoperative thoracotomy wounds. The delimited foci of purulent mediastinitis were opened and sanitized (necrotic tissues were excised and removed). Preventive hemostatic methods were used in the area of pressure ulcers from drainage tubes. Replacing and changing the position of the drainage tubes in the mediastinum was a strictly compulsory technique. Pus and necrotic soft tissue that appeared in the thoracotomy wound were subsequently eliminated by a device consisting of two titanium brackets connected by a lock embodied in the form of an oval ring during the wound suturing at the stage of programmed re-thoracotomy. The groups were comparable in age and comorbidities. The average diagnosis of spontaneous esophageal rupture took 3.5 days; the maximum time is 10 days. The statistical significance of differences in immune status indicators was assessed by using the Student's t-test and Pearson's 2 test. Results. A systematic approach using the tactical and technical surgical techniques developed by us (such as suturing esophageal wall defects regardless of the rupture time, multifunctional nasoesophagogastric tube installation; the imposition of a purse string suture to prevent reflux from the stomach into the esophagus; programmed re-thoracotomy using the method of temporary fixation of the ribs) allowed to reduce the number of complications, such as haemorrhage from the mediastinal vessels, by 3 times, sepsis 1.5 times, mortality almost 2 times. Conclusion. The introduction of patented techniques allowed to reduce the number of life-threatening complications and mortality in patients with spontaneous rupture of the esophagus complicated by purulent mediastinitis.

A mechanism of abnormal motility of the esophagus and stomach and associated sound phenomenon

The aim of the article is to update the pathophysiological mechanisms that cause the appearance and activation of pathological peristalsis of the esophagus and stomach and associated esophageal-gastrointestinal-diaphragmatic noise, described earlier, designed to expand the diagnostic capabilities of physical methods for diagnosing hiatal hernia and to facilitate the differential diagnosis of this disease with other diseases of the chest. The result of the study is to describe 5 the pathophysiological mechanisms of developing hernia hiatal and lead to the emergence of pathological motility of the esophagus and stomach in the form of the strengthening or emergence of antiperistaltic waves. The resulting acoustic phenomenon is the essence of a new physical symptom in this disease - esophageal-gastrointestinal-diaphragmatic noise. The first mechanism that determines the pathological motor activity of the smooth muscle cells of the esophageal wall is the so-called esophageal “cleansing” peristalsis, which prevents the regurgitation of the acidic contents of the stomach into the esophagus, where the environment is normally neutral. The second mechanism that causes the appearance and strengthening of pathological peristalsis of the stomach is the deformation during the passage of its part through the esophageal opening of the diaphragm into the chest cavity. The third mechanism that determines the occurrence of pathological peristalsis of the esophagus and stomach is a violation of the secretion and metabolism of nitric oxide in diaphragmatic hernias. The fourth mechanism that leads to the appearance of esophageal-diaphragmatic noise is the pathological peristalsis of the esophagus and stomach in patients with hiatal hernia, which causes the appearance of antiperistaltic waves accompanied by gastro-esophageal reflux and manifests itself in clinically pathological belching. The fifth mechanism that causes pathological peristalsis of the esophagus is the phenomenon of hydrodynamic cavitation, which occurs as a result of regurgitation of the contents of the stomach into the esophagus. Understanding the pathophysiological mechanisms that cause the appearance of pathological peristalsis and antiperistalsis of the esophagus and stomach in patients with diaphragmatic hernia allows us to understand the causes of the sound phenomenon and the associated physical symptom in this disease.

Repair of a three-way congenital bronchoesophageal fistula in an adult patient: a case report

Background The incidence of congenital bronchoesophageal fistulas in adults is rare. Most fistulas discovered in adulthood are often small and can be repaired with a simple one-step method. Case presentation A 46-year-old female patient complained of a 2-month history of chocking, coughing, and a 12 kg drop in weight. The bronchofiberscopy and gastroscopy showed a large fistula, which extended from the esophagus to the main bronchus on both sides, thus forming a special three-way channel which has never been reported. This case was challenging both to the anesthetists and surgeons. The patient was intubated with a sengstaken-blakemore tube, and then received segmental esophageal resection, anastomotic reconstruction, and double-flap repair with esophagus segment in situ. Conclusion When the fistula in BEF is large or complicated, appropriate surgical methods should be meticulously designed according to the condition of the patient. The problem of anesthesia intubation should be solved first, to allow a smooth operation. Secondly, a double-layer repair of the airway fistula by using esophageal wall tissues as patch materials is proposed.

Diagnostic challenge and surgical management of Boerhaave’s syndrome: a case series

Background Boerhaave’s syndrome is the spontaneous rupture of the esophagus, which requires early diagnosis and treatment. Symptoms may vary, and diagnosis can be challenging. Case presentation Case 1: A 54-year-old Chinese man presented to us with sudden-onset epigastric pain radiating to the back following hematemesis. Upper gastrointestinal endoscopy revealed a full-thickness rupture of the esophageal wall. Subsequent computed tomography showed frank pneumomediastinum and heterogeneous pleural effusion. Immediately, esophageal perforation repair operation and jejunostomy were performed. The postoperative period was uneventful, and he was discharged. Case 2: A 62-year-old Chinese man was admitted to the emergency department with thoracic dull pain and chest distress. Chest computed tomography scan showed pneumomediastinum and large left-sided pleural effusion. Esophagus fistula was confirmed by contrast esophagography. Then, we performed thoracotomy to repair the esophageal tear as well as to debride and irrigate the left pleural space. His postoperative period was uneventful, with no leakage or stricture. Case 3: The patient was a 69-year-old Chinese male presenting with severe retrosternal and upper abdominal pain following an episode of forceful vomiting. Thoracic computed tomography scan revealed a rupture in the left distal part of the esophagus, a pneumomediastinum, and left-sided pleural effusions. Conservative treatment failed to improve disease conditions. Open thoracic surgery was performed with debridement and drainage of the mediastinum and the pleural cavity, after which he made a slow but full recovery. Conclusions We highlight that early diagnosis and appropriate surgical treatment are essential for optimum outcome in patients with esophageal rupture. We emphasize the importance of critical care support, particularly in the early stages of management.

En Bloc Resection of Primary Large Esophageal Mucosa-Associated Lymphoid Tissue Lymphoma by Endoscopic Submucosal Dissection: A Case Report

Treatment of mucosa-associated lymphoid tissue (MALT) lymphoma has recently received considerable attention. Here, we report a case of large esophageal MALT lymphoma that was successfully en bloc resected using endoscopic submucosal dissection (ESD). A 77-year-old woman was admitted to our hospital with progressive dysphagia for more than 2 months. Upper gastrointestinal endoscopy revealed a large rounded submucosal mass covered by normal mucosa, located at the lower esophagus. Endoscopic ultrasonography (EUS) showed a well-demarcated hypoechoic mass chiefly located in the esophageal wall, but the layers of the esophageal wall were not clear. ESD was performed for diagnostic and treatment purposes. No complications occurred during or after ESD. The resected specimen measured 4.3 cm × 2.8 cm × 1.5 cm. The histologic findings were diagnostic of esophageal MALT lymphoma. Infiltration of neoplastic cells in the lateral margins of the resected specimen was not observed. However, vertical margins showed an R1 situation and mild damage to the muscularis propria. After 3 months, her dysphagia disappeared. Additional radiation therapy was then administered. After 5 months, the patient was still under surveillance and free of recurrent disease. Resection with ESD of such a large mass of MALT in the esophageal region has rarely been reported before in the literature.
