Comparison of the clinical effectiveness of hepaticojejunostomy and self-expanding metal stents for bypassing the bile ducts in patients with unresectable pancreatic head cancer complicated by obstructive jaundice.

OBJECTIVE: Aim: To improve treatment outcomes of patients with unresectable pancreatic head cancer complicated by obstructive jaundice by improving the tactics and techniques of surgical interventions. PATIENTS AND METHODS: Materials and Methods: Depending on the treatment tactics, patients were randomised to the main group (53 people) or the comparison group (54 people). The results of correction of obstructive jaundice by Roux-en-Y end to side hepaticojejunostomy (main group) and common bile duct prosthetics with self-expanding metal stents (comparison group) were compared. RESULTS: Results: The use of self-expanding metal stents for internal drainage of the biliary system compared to hepaticojejunostomy operations reduced the incidence of postoperative complications by 29.9% (χ2=13.7, 95% CI 14.38-44.08, p=0.0002) and mortality by 7.5% (χ2=4.16, 95% CI -0.05-17.79, p=0.04). Within 8-10 months after biliary stenting, 11.1% (6/54) of patients developed recurrent jaundice and cholangitis, and another 7.4% (4/54) of patients developed duodenal stenosis with a tumour. These complications led to repeated hospitalisation and biliary restentation in 4 (7.4%) cases, and duodenal stenting by self-expanding metal stents in 4 (7.4%) patients. CONCLUSION: Conclusions: The choice of biliodigestive shunting method should be selected depending on the expected survival time of patients. If the prognosis of survival is up to 8 months, it is advisable to perform prosthetics of the common bile duct with self-expanding metal stents, if more than 8 months, it is advisable to perform hepaticojejunal anastomosis with prophylactic gastrojejunal anastomosis.

PALLIATIVE SURGICAL TREATMENT OF PATIENTS WITH UNRESECTABLE CANCER OF THE HEAD OF THE PANCREAS COMPLICATED BY MECHANICAL JAUNDICE.

OBJECTIVE: The aim: To improve the results of palliative surgical treatment of patients with unresectable cancer of the head of the pancreas, complicated by obstructive jaundice, disturbances of evacuation from the stomach, cancerous pancreatitis by improving surgical tactics and techniques of surgical interventions.. PATIENTS AND METHODS: Materials and methods: There were 277 patients with unresectable cancer of the head of the pancreas participated in the study, who were divided into control (n=159) and main (n=118) groups depending on treatment tactics. RESULTS: . Results: The operation of choice in the surgical treatment of patients with unresectable cancer of the head of the pancreas, complicated by obturation of the biliary system and duodenum with a high surgical risk is endoscopic stenting of the bile ducts and duodenum with nitinol stents, which is accompanied by a decrease in the frequency of postoperative complications from 72.7 to 29.6% (χ2=5.8, 95% CI 8.26-65.39, p=0.01), mortality from 36.4% to 0.0% (χ2=10.69, 95% CI 11.8- 64.65, p=0.001). The patient's formation of biliodigestive and prophylactic gastrodigestive anastomosis is an effective and safe procedure, which, in comparison with only biliodigestive shunting, reduces the frequency of postoperative complications by 16.2% (χ2=6.61, 95% CI 3.69-30.89, p=0.01), improves quality of life and prevents repeated surgical operations to restore evacuation from the stomach. CONCLUSION: Conclusions: The use of the proposed surgical tactics and technique of surgical interventions in patients with unresectable cancer of the head of the pancreas, complicated by obstructive jaundice, disturbances of evacuation from the stomach, cancerous pancreatitis made it possible to reduce the frequency of complications by 9.3% (χ2=3.94, 95% CI 0.09-17.86, p=0.04) and fatal cases by 5.8% (χ2=4.5, 95% CI 0.42-12.72, p=0.03).
