RESUMO

OBJECTIVE: To improve the outcomes in patients with malignant obstructive jaundice using intraluminal stenting. MATERIAL AND METHODS: The present study included 62 patients with clinical symptoms of malignant obstructive jaundice. In the main group, we performed biliary stenting with self-expanding multi-perforated stents (Hanarostent Multi-hole Biliary). Microscopic perforations of these stents prevent migration and reduce the risk of blocking the cystic and main pancreatic ducts. In the control group, stenting was performed with fully and partially covered self-expanding stents. RESULTS: Lower incidence of obstructive cholecystitis and acute pancreatitis in the main group was associated with multiperforated stents reducing the risk of blocking the main pancreatic and cystic ducts. CONCLUSION: In our study, multiperforated stents excluded migration and reduced the incidence of complications (acute cholecystitis from 11.5 to 3.8%, acute pancreatitis from 15.3 to 7.7%).

RESUMO

Cholelithiasis complicated by cholecystoduodenal fistula and small bowel biliary obstruction is an absolute indication for surgical treatment. Modern possibilities of intraluminal endoscopy (electrohydraulic lithotripsy) made it possible to avoid intra-abdominal access (laparotomy, laparoscopy) and postoperative complications. Finally, rapid rehabilitation was noted.

RESUMO

OBJECTIVE: To improve treatment outcomes in patients with acute pancreatitis through a differentiated approach to transluminal drainage. MATERIAL AND METHODS: There were 1074 patients with acute pancreatitis between January 2018 and December 2021 at the Sklifosovsky Research Institute for Emergency Care. EUS was used as a final diagnostic method to determine localization, dimensions, shape and contours of fluid collections. We also assessed content, presence or absence of a capsule and connection with pancreatic ductal system, possibility of intraluminal drainage under EUS control. A plastic stent with rounded ends was installed if homogeneous hypo- and anechoic cavity with clear even contours was detected. The same measure was applied in case of aspiration of serous or serous-hemorrhagic fluid. The indication for installation of covered self-expanding endoprosthesis was inhomogeneous anechoic fluid collection with hyperechoic inclusions (sequesters) and cloudy purulent content. Patients with necrotic forms underwent insertion of a cystonasal drainage tube 7Fr for sanitation of the cavity with 0.05% aqueous chlorhexidine solution. Endoscopic sequestrectomy was performed every 24-48 hours. Stent was removed in 6 (for encapsulated peripancreatic fluid collections) or 1 month (for other types of fluid collections) after discharge. RESULTS: According to the EUS data, endoscopic TLD was performed in 63 (46%) out of 136 patients with fluid collections. Among 63 patients with TLD, connection with pancreatic ductal system was found in 5 (7.9%) patients. These ones underwent pancreaticoduodenal stenting. Twenty-two patients underwent elective sequestrectomy after stenting of necrotic types of fluid collections with fully covered self-expanding stents. Additional percutaneous drainage was required in 11 (45.8%) of 24 patients. Complicated postoperative period was observed in 4 (6.3%) patients with acute necrotic fluid collections (bleeding from the area of pancreatogenic destruction). Four (6.3%) patients died. Autopsy revealed resolution of purulent-inflammatory process in all patients. CONCLUSION: Intraluminal surgery is possible not only for homogeneous delimited fluid collections, but also for advanced lesions including infected destructions. This approach allows us to consider endoscopic intraluminal drainage as the final minimally invasive method of surgical treatment of pancreatic necrosis. Its effectiveness is up to 45.8%.

RESUMO

OBJECTIVE: To evaluate the effectiveness of intraluminal drainage of acute fluid accumulations for infected pancreatic necrosis. MATERIAL AND METHODS: There were 848 patients with acute pancreatitis between January 2018 and December 2020 at the Sklifosovsky Research Institute for Emergency Care. Necrotizing pancreatitis was detected in 232 (27.4%) patients. Among necrotic forms, pancreatic parenchymal necrosis was detected in 56 (24.1%) patients, its combination with peripancreatic necrosis - in 176 (75.9%) patients. All patients underwent transabdominal ultrasound, CT of the abdomen and retroperitoneal space, esophagogastroduodenoscopy, endo-ultrasonography of pancreatobiliary zone. Dimensions and localization of acute necrotic accumulations were established using ultrasound and CT data. Endoscopic transluminal drainage was performed in 22 patients with necrotizing pancreatitis and fluid accumulations attached to the stomach or duodenum. There were 12 men (55%) and 10 women (45%) aged 48.5 [39; 56] (35; 88) years. Effectiveness of endoscopic treatment was assessed considering clinical, endoscopic data and reduction of fluid accumulations confirmed by ultrasound and CT data. RESULTS: Among 22 patients, connection with pancreatic ductal system was detected in 3 patients (13.6%) that required pancreaticoduodenal stenting. Early postoperative period was complicated by bleeding from the area of pancreatogenic destruction in 4 patients (18.1%). Therefore, angiography and endovascular embolization of a. gastroduodenalis were required in 2 (9.1%) cases. In 1 (4.5%) case, we performed endoscopic hemostasis using Hemoblock hemostatic solution (4 ml). Combination of both methods was used in 1 (4.5%) patient. In 11 (50%) patients, endoscopic drainage was the final method of surgical treatment of necrotizing pancreatitis. Four patients (18.1%) died. Multiple organ failure caused mortality in 3 patients (13.6%). One (4.5%) patient died from severe nosocomial pneumonia developed in 32 days after drainage. Spurs not drained into the stomach with US-confirmed suspension and sequestration were observed in 11 (50%) out of 22 patients. These accumulations required additional ultrasound-assisted percutaneous drainage. CONCLUSION: Endoscopic transluminal drainage is a perspective minimally invasive method for necrotizing pancreatitis.

RESUMO

OBJECTIVE: To develop the indications and assess an effectiveness of treatment of patients with ampullary tumors followed by mechanical jaundice. MATERIAL AND METHODS: There were 26 patients with major duodenal papilla neoplasms for the period 2015-2020 at the Sklifosovsky Research Institute for Emergency Care. RESULTS: Twenty patients underwent transpapillary interventions: papillosphincterotomy followed by lithoextraction and bilio-duodenal stenting in 4 (15.3%) patients, bilio-duodenal stenting in 12 (46.1%) patients, nasobiliary drainage in 2 (7.6%) patients, pancreaticoduodenal stenting in 2 (7.6%) patients. Percutaneous transhepatic microcholecystostomy was performed in 6 (23.4%) patients. In all cases, laboratory values decreased in 5-7 days after drainage. Eight (30.7%) patients refused further surgical treatment and were discharged in satisfactory condition. Another 8 (44.5%) patients underwent endoscopic submucosal papillectomy. There were no postoperative complications. Patients were discharged after 5-7 days. Four (22.2%) patients underwent tumor resection via laparotomy. One of these patients required redo laparotomy in postoperative period due to acute perforated duodenal ulcer. Six (33.3%) patients underwent palliative bilio-duodenal stenting. CONCLUSION: Invasion of muscle layer or distal parts of the common bile duct, as well as abnormal vascularization are indications for open surgery or palliative endoscopic treatment. Tumor location within mucous and muscle layers without invasion of distal third of the common bile duct and no abnormal vascularization of tumor justify endoscopic papillectomy. Endoscopic approach can be considered as a final minimally invasive method with minimal risk of postoperative complications in case of benign ampullary tumor.

RESUMO

OBJECTIVE: To report initial experience of endoscopic transluminal drainage of infected pancreatic necrosis. MATERIAL AND METHODS: There were 8 patients with acute severe pancreatitis and large-focal pancreatic necrosis who underwent transluminal drainage of destruction zones for the period from December 2018 to October 2019. RESULTS: Transluminal drainage of pancreatogenic destruction zones in acute severe pancreatitis can be considered as the only surgical approach in 50% of cases that is comparable with literature data.
