[Pancreatic isthmus intersection with preliminary suturing of arteries in this area]. / Sposob peresecheniya peresheika podzheludochnoi zhelezy s predvaritel'nym proshivaniem arterial'nykh sosudov dannoi oblasti.

OBJECTIVE: To analyze the early results of pancreatoduodenectomies with different methods of pancreatic isthmus transection. MATERIAL AND METHODS: There were 82 pancreatoduodenectomies for cancer of pancreatic head or major duodenal papilla for the period 2010-2019. The control group comprised 38 patients with pancreatic isthmus transection and no preliminary suturing of local vessels. The study group consisted of 44 patients who underwent preliminary intersection of pancreatic isthmus vessels. Inclusion/exclusion criteria were used for grouping. We evaluated total intraoperative blood loss and blood loss following pancreatic isthmus transection, incidence and structure of postoperative complications. RESULTS: Total intraoperative blood loss was 755.12±108.61 vs. 698.45±92.87 ml, respectively (p>0.05). Intraoperative blood loss following pancreatic isthmus transection was 48.21±9.11 vs. 7.83±1.72 ml, respectively (p<0.01). Incidence of postoperative complications and redo surgeries was similar. Postoperative bleeding occurred in 5 (13.15%) patients of the 1st group (class A - 2.63%; B - 5.26%; C - 5.26%) and 2 (4.54%) patients of the 2nd group (A - 4.54%; B and C - 0%). There were no significant differences in the incidence of other complications and postoperative mortality. CONCLUSION: Pre-stitching of arterial vessels of the pancreatic isthmus reduces blood loss following intersection (p<0.01), as well as the incidence of postoperative bleeding class B and C (p<0.05).

[Surgical treatment of a patient with liver endometriosis]. / K voprosu ob endometrioze pecheni.

Endometriosis is a functioning endometrial tissue outside the inner layer of the uterine wall. Liver endometriosis is one of the rarest forms of atypical endometriosis. In this article, we report a patient with this disease. A 59-year-old patient complained of heaviness and periodic pain in the right hypochondrium for more than a year. Previous contrast-enhanced CT revealed signs of cystic-solid hypovascular mass lesion in the right liver lobe. Histological examination revealed no reliable signs of tumor growth. According to control CT after 8 months, no significant changes were observed. Surgical treatment was indicated and atypical liver resection was performed. Histological examination revealed cystic endometrioid lesion. Liver endometrioma is a rare disease with unclear pathogenesis. Diagnosis is difficult due to uncharacteristic clinical manifestations and no specific markers. Liver endometriosis should be considered in differential diagnosis of liver lesion. Surgical treatment is preferable due to the risk of malignant transformation.

[Technique of invaginative pancreatojejunostomy in pancreatectomy]. / Pogruzhnoi kisetnyi invaginatsionnyi anastomoz pri rezektsionnykh operatsiiakh na podzheludochnoi zheleze.

Pancreatoenterostomy is one of the key moments in pancreatic surgery. It was proposed invaginative pancreatojejunostomy in end-to-side fashion by using of two continuous single-row purse-string sutures. This technique may be used in pancreatoduodenectomy and Beger's procedure. This method will be useful in cases of edematous and erupting pancreatic parenchyma and hard-to-differentiate lumen of pancreatic duct. It is followed by reduced trauma of tissue and bleeding, allows to avoid sutures failure and to achieve sealed anastomosis.

[Surgical technique in patients with chronic pancreatitis]. / Optimizatsiia tekhniki operatsii u bol'nykh khronicheskim pankreatitom.

AIM: To justify ligation of vascular branches of anterior pancreateroduodenal arterial arch or gastroduodenal artery prior to bifurcation. MATERIAL AND METHODS: This method was tested on sufficient clinical material: 147 patients with recurrent chronic pancreatitis. The interventions are presented by Frey, Beger procedures and its Berne variant. RESULTS: Comparative analysis showed reliable advantages of vascular ligation during pancreatectomy.

[THE DIAGNOSTIC AND TREATMENT ALGORITHM FOR PATIENTS WITH OBSTRUCTIVE JAUNDICE SYNDROME].

The article presents a comparative analysis of therapeutic and diagnostic measures aimed at eliminating jaundice complicating diseases hepatopancreatoduodenal zone as tumor and benign etiology. Patients with obstructive cholestasis were represented by two groups: the main and control, including 858 and 869 patients, respectively. Therapeutic and diagnoctic tactics in the study group was based on the principles of the proposed algorithm. Using the proposed diagnostic and treatment algorithm led to better outcomes: significantly lower mortality and the incidence of postoperative complications
