The Use of Esophageal Stents in the Management of Postoperative Fistulas-Current Status, Clinical Outcomes and Perspectives-Review.

Esophageal fistula remains one of the main postoperative complications, with the treatment often requiring the use of stents. This article reviews the updates on the use of endoscopic stents for the treatment of postoperative esophageal leakage in terms of indications, types of stents used, efficiency, specific complications and perspectives. MATERIALS AND METHODS: We searched the PubMed and MEDLINE databases for the keywords postoperative esophageal anastomotic leak and postoperative esophageal anastomotic leak stent, and retrieved relevant papers published until December 2022. RESULTS: The endoscopic discovery of the fistula is usually followed by the insertion of a fully covered esophageal stent. It has an efficiency of more than 60% in closing the fistula, and the failure is related to the delayed application of the method, a situation more suitable for endo vac therapy. The most common complication is migration, but life-threatening complications have also been described. The combination of the advantages of endoscopic stents and vacuum therapy is probably found in the emerging VACstent procedure. CONCLUSIONS: Although the competing approaches give promising results, this method has a well-defined place in the treatment of esophageal fistulas, and it is probably necessary to refine the indications for each individual procedure.

The Role of Esophageal Stenting in the Management of Anastomotic Leaks after Esophageal and Esophago-Gastric Cancer Resections. Literature Review.

Introduction: Anastomotic fistulas after surgery for esophageal cancer, remain a challenge for both the surgeon and the gastroenterologist. The aim of the study is to highlight the role of esophageal stenting in the management of leaks after esophagectomy for malignancies. Materials and Methods: We reviewed the available literature on the endoscopic treatment of esophageal anastomotic leaks, especially articles on endoscopic stenting in the management of this complication. Pubmed and ClinicalKey databases were searched using keywords such as esophageal anastomotic leaks, fully covered self-expanding metal stents, esophageal neoplasm. The relevant literature has been reviewed and included in the article. Results and Conclusions: The insertion of self-expanding stents in the fistulas of the esophageal anastomosis, represents an efficient method of treatment both for the closure of the fistula and in the control of sepsis. The morbidity and mortality associated with this method of treatment may be significant.

Management of Esophageal Perforations During Achalasia Treatment Experience of the General and Esophageal Surgery Clinic, Sf Maria Hospital.

Introduction: Achalasia is a motility disorder characterized by the absence of optimal relaxation of the lower esophageal sphincter (LES) with swallowing and lack of peristalsis of the esophageal body. Excepting temporary medical options, the treatment aims to lower the LES pressure by endoscopic or surgical means. Either method involves a risk of perforation. We analyzed the management of esophageal perforations in patients who received treatment for achalasia. Material and Method: we conducted a retrospective study of patients with achalasia hospitalized and treated in the Clinic of General and Esophageal Surgery within the Sf. Maria Clinical Hospital in Bucharest between January 2016 and December 2021. Results: There were 57 patients, 35 men, with a mean age of 50 years and a mean duration of symptoms of 35 months. Almost all (91.89%) patients presented with dysphagia. Preoperative manometry was performed in 52 patients, of whom 17 were type I, 35 were type II. The treatment was laparoscopic Heller eso-cardiomyotomy (LHM) in most cases (55), with Dor anterior fundoplication. There were 10 recurrent cases after dilation or surgery in another medical unit. There were 3 mucosal perforations after LHM. The treatment varied from simple suture to a combined endoscopic and surgical approach, involving the use of esophageal stent, abscess drainage, and feeding jejunostomy. We also present the management of two cases of esophageal perforation after endoscopic dilation, in which the support of the surgical team was necessary. Conclusion: Esophageal perforation in the treatment of achalasia, either endoscopic or surgical, requires immediate identification and treatment to provide the best chance of favorable evolution. The treatment of achalasia is indicated to be performed in dedicated centers, prepared even in case of complications.

Single Center Experience in Pancreatic Surgery.

Introduction: We present our department experience in pancreatic surgery over the last 6 years. From its inception the number of pancreatic resections has been continuously growing each year. Method: We performed a retrospective analysis of a prospectively maintained database where we included all the patients with pancreatic resections over the last 6 years. We present the main indication and the different types of pancreatic resections, postoperative morbidity, intrahospital and 90-day mortality and an analysis of survival for the patients with pancreatic ductal adenocarcinoma. Results: We analyzed 198 patients, 193 with pancreatic resections and 5 patients with open surgery microwave ablation. There were 145 pancreaticoduodenectomies, 37 distal pancreatectomies, one total pancreatectomy, 3 distal pancreatectomies with celiac axis resection and 7 surgical interventions for chronic pancreatitis. Conclusion: We presented our center's experience in pancreatic surgery with good overall results, however, there is still room for continuous improvement and refinements to achieve better shortterm outcomes, regarding postoperative morbidity and mortality.

Triple Antioxidant Therapy, an Alternative for Patients with Chronic Liver Disease - A Prospective Multicenter Interventional Study.

Background: Non-alcoholic fatty liver disease (NAFLD) has increased exponentially in recent years in Western European countries, where the number of hepatitis of viral etiology has been declining, and it is thought to be the most common cause of chronic liver disease in the near future (1). Currently, NAFLD is both the second most common cause of hepatocellular carcinoma (HCC) and the second most common indication for liver transplantation (2-4). This problem is very serious, as cases of NAFLDs are increasingly in children, a population with a long life ahead, and in whom the disease has all the time to progress to cirrhosis and HCC (5, 6). Objectives: The goal of this prospective study is to determine the effect of an original formula consisting in silymarin, organic selenium and alpha lipoic acid, in reducing liver damage in patients with chronic liver disease. Material and methods: The study started in March 2018, initially with a group of patients from Bucharest, integrated in the study at St. Mary's Hospital. In October 2018 it was expanded at the national level to 1 718 patients, monitored by 145 investigating physicians from 134 centers, with an average of 11.8 patients per investigating physician. Outcomes: Taking each stage of fatty liver disease (FLD) at T0 moment (the beginning of the study), we observed that 25% of patients with grade I FLD had no sign of disease at the end of the study, 74% of those with grade II FLD recovered or improved their health, and 83% of patients with grade III FLD recovered or improved their health. There were 149 patients with no FLD detected at the end of the study (recovered). Conclusion: Based on triple antioxidant therapy, the original formula improved the evolution and prognosis of patients with chronic liver disease.

Postoperative Esophageal Leaks in Malignant Pathology - Optimal Management: A Systematic Review.

BACKGROUND AND AIMS: Postoperative esophageal leaks are one of the major causes of postoperative mortality and morbidity. The purpose of this study was to review current knowledge of current methods of diagnosis and management of postoperative esophageal leaks. Methods: A systematic literature search was performed in the PubMed/Medline database using the terms "postoperative esophageal leaks" and "postesophagectomy complications" to identify articles relevant to the current diagnostic and prophylactic and curative treatment of post-oesophagectomy anastomotic fistulas. Results: Several papers have shown that the incidence of fistulas varies and is dependent on several factors: the location of the anastomosis, the type of suture used, the biological condition of the patient. Due to the severity of the mediastinal anastomotic fistula, great importance is being given to the methods of preventing its occurrence by intraoperative testing or improving the gastric tube vascularity. The most recent articles present endoscopic methods of treating this complication by using coated esophageal stents and endoluminal vacuum therapy. CONCLUSION: In patients with mediastinal postoperative esophageal fistulas, diagnosis and management represent a real challenge for the surgeon-endoscopist-therapist team. The early diagnosis and the establishment of an optimal therapy to address the parietal defect and the biological status of the patient are mandatory conditions for resolving this postoperative complication.
