[Laparoendoscopic hybrid treatment of a patient with choledocholithiasis, cholecystitis and large duodenal diverticula].

We present laparoendoscopic hybrid treatment of a patient with choledocholithiasis, cholecystitis and large duodenal diverticula. A 69-year-old patient underwent one-stage hybrid laparoendoscopic intervention. Despite the difficult situation caused by large duodenal diverticula and calculus in terminal part of common bile duct, hybrid technique with rendez-vous procedure allowed successful lithoextraction and cholecystectomy.

[Intraductal radiofrequency ablation for neoplasms of the major duodenal papilla with intraductal spread].

Objective: To analyze the efficacy of intraductal radiofrequency ablation (RFA) for neoplasms of the major duodenal papilla with intraductal spread.

Material And Methods: Eleven patients with adenomas of the major duodenal papilla and intraductal spread underwent intraductal RFA between 2022 and 2023. Spread to the common bile duct ranged from 10 to 30 mm, to the main pancreatic duct - from 5 to 11 mm.

[Intraductal radiofrequency ablation under endosonography and cholangioscopy for residual adenoma of the major duodenal papilla with intraductal component].

All adenomas of the major duodenal papilla (MDP) require resection regardless of morphological structure due to high risk of malignancy. Currently, intraluminal endoscopic interventions are preferable for these adenomas. MDP neoplasms with intraductal spread (type III and IV) are of particular difficulty for endoscopic techniques.

[Endoscopic treatment of recurrent Zenker diverticulum and postoperative esophageal stricture].

Zenker diverticulum is a rare disease accounting for 1.5-5% of esophageal diverticula. For a long time, surgical treatment of Zenker pharyngoesophageal diverticula implied open diverticulectomy via cervical approach.

[Hybrid laparo-endoscopic access for giant fibrovascular esophageal polyp: a case report].

Fibrovascular polyp is a rare non-epithelial esophageal tumor arising from submucosal layer and consisting of connective and adipose tissue, as well large number of vessels. Large tumors can cause dysphagia, vomiting, chest pain, shortness of breath and/or asthma, while giant neoplasms are potentially life threatening. Despite active introduction of minimally invasive treatment of patients with non-epithelial gastrointestinal tumors, there are still difficulties in surgical treatment of fibrovascular polyps.

[Difficulties in diagnosis of neuroendocrine tumors of the gastrointestinal tract].

We present diagnosis and complex minimally invasive surgical treatment of a patient with long-standing neuroendocrine tumor of the upper gastrointestinal tract. We followed-up a 50-year-old female patient after endoscopic resection of polypoid neoplasm of the stomach for 2 non-organ retroperitoneal neoplasms in the area of hepatogastric ligament. After a comprehensive examination and minimally invasive surgery including laparoscopic resection of retroperitoneal neoplasms, immunohistochemical examination, PET-CT and targeted endoscopic ultrasound of the stomach, we diagnosed a highly differentiated gastric neuroendocrine tumor with metastases into lymph nodes of hepatogastric ligament.

[Complex endoscopic treatment of a patient with a large adenoma of the major duodenal papilla, choledocholithiasis and stricture of the common bile duct].

Incidence of adenomas of the major duodenal papilla has increased in recent years due to widespread endoscopic screening. These adenomas require resection due to high risk of malignant transformation. Currently, minimally invasive endoscopic interventions are often considered as an alternative to surgical treatment.

[Hybrid laparo-endoscopic gastric resection for non-epithelial pyloric tumor].

In January 2020, a patient with a gastrointestinal stromal tumor of the antrum located in close proximity to the pylorus underwent a hybrid laparo-endoscopic organ-sparing gastric resection. There were no intraoperative and postoperative complications. Control endoscopic and X-ray examination of the stomach confirmed normal motor and evacuation function of the stomach.

[Laparoscopic reconstructive Roux-en-Y hepaticojejunostomy].

Intraoperative damage to the bile ducts following laparoscopic cholecystectomy is still one of the urgent problems of modern minimally invasive surgery. In some cases, these complications lead to patient disability, deterioration in their quality of life and need for redo surgery including technically difficult procedures. Modern endoscopic technologies are essential in the treatment of postoperative benign strictures of the common bile duct.

[Endoscopy-assisted dilatational tracheostomy in patients with COVID-19].

Objective: To summarize an experience of endoscopy-assisted dilatational tracheostomies in patients with COVID-19.

Material And Methods: There were 31 endoscopy-assisted dilatational tracheostomies in patients with COVID-19 for the period from April 17 to June 10, 2020 (11 women and 19 men). Mean age of patients was 66.

[Endoscopic treatment of esophageal anastomotic leakage using vacuum-assisted closure system].

Objective: To analyze the effectiveness of vacuum-assisted closure system for esophageal anastomotic leakage.

Material And Methods: There were 10 patients with upper gastrointestinal anastomotic leakage who were treated at our institution in 2015-2018. Vacuum aspiration system was applied in all cases.

[Diagnosis of neuroendocrine neoplasms of the pancreas].

The rare clinical case of multiple primary gastrointestinal stromal tumors (GIST) in one patient is presented in the article. The analysis of the available material confirmed that there is the problem of early detection of this type of tumors and their differential diagnosis. The minutes of outpatient radiological methods of research should include methods of identifying GIST in various locations.
