The OBJECTIVE was to study the efficacy and safety of laparoscopic decompression of the celiac trunk. METHODS AND MATERIALS. A comparative analysis of the results of laparoscopic (30 patients) and conventional decompression of the celiac trunk (50 patients) was carried out. All patients were operated on between September 2018 and July 2021. RESULTS. Intraoperative bleeding during laparoscopic decompression of the celiac trunk, which required conversion of access to laparotomy and vascular suture, was noted in 2 (6.7 %) cases. With conventional access, there were no such complications. The average duration of laparoscopic decompression of the celiac trunk was 107 minutes, from conventional access – 150 minutes. The average length of hospital stay after laparoscopic intervention was 4 days, after the traditional one – 7 days. Long-term results of treatment over a period of more than 6 months were evaluated in 28 patients who underwent laparoscopic decompression of the celiac trunk and 45 people who underwent conventional decompression. Ultrasound examination in all cases stated the return of linear and velocity parameters of blood flow in the celiac trunk to normal. complete relief of the clinical manifestations of the disease was achieved in 24 (85.7 %) patients after laparoscopic and in 39 (86.7 %) after traditional intervention. CONCLUSION. Laparoscopic decompression of the celiac trunk is an effective method of surgical treatment of the syndrome of compression of the celiac trunk, but there are risks of vascular damage. The long-term results of laparoscopic and open decompression of the celiac trunk are comparable.

The Objective was to pay attention to the rare combination of a true aneurysm of the inferior phrenic artery and the syndrome of compression of the celiac trunk, its open decompression and elimination of aneurysms in three patients. Methods and Materials . From September 2018 to December 2022, in 5 patients with celiac trunk compression syndrome (three men; mean age 49.4 years, from 18 to 72 years) out of 182, according to MSCT angiography and during surgery, an aneurysm of the right inferior phrenic artery was detected in two and left for three. These arteries originated from the post-stenotic moderately dilated part of the celiac trunk. Results . On average, its diameter at the site of stenosis was 1.9 mm and the degree was 58 %, the trunk was 8.6 mm and the aneurysm was 6.8 mm, and its length was 8 mm. In 4 cases, the aneurysm originated from the ostium of this artery and in one case, 5 mm from it, without involvement of the celiac trunk. All 5 aneurysms were concentric sac-shaped, including a funnel-shaped variant in two of them. Three out of 5 patients successfully underwent open decompression of the celiac trunk and immediately resection of the aneurysm in two with the imposition of a lateral suture and ligatures on the artery, respectively, and exclusion in one with a purse-string suture. Conclusion . An aneurysm of the inferior phrenic artery originating from the celiac trunk may be one of the specific manifestations of its long-term significant diaphragmatic compression. With such a combination of lesions, the expediency of decompressing the celiac trunk and removing the aneurysm from the bloodstream, regardless of its size, should be considered.

Purpose of the study. The reasons for the unsatisfactory results of surgical treatment of patients with celiac artery compression syndrome (CACS) and the role of repeated interventions allows to achieve a lasting improvement in most of them. The purpose of the study is to clarify the reasons for the unsatisfactory outcomes of surgical treatment of patients with CACS and the nature and significance of repeated operations.Patients and methods. From 860 patients with CASC who were operated on over the past 25 years 82 patients were selected with unsatisfactory treatment results. Initial conventional abdominal surgery was performed in 26 (31.7%) patients without a positive outcome before decompression of celiac artery (DCA). Primary operations were performed in 82 patients with proven CASC, of which 69 (84.1%) had DCA in open approach, isolated in 43 (52.4%) and combined in 26 (31.7%). Embolization of PDA aneurysm in one (1.2%) patient. In other medical institutions 15 (18.3%) patients were operated, among them 3 (3.7%) patients had DCA in open approach, in 4 (4.9%) laparoscopic DCA, in 6 (7.3%) angioplasty and emergency stenting and two (2.4%) reconstructive operations, all technically and clinically unsuccessful.Results. After DCA in open approach 51 (73.9%) patients of 69 patients had normal celiac artery flow. 4 patients had unresolved stenosis of the celiac artery and 15 relapsed its stenosis, one of them with residual stenosis after DCA twice, which amounted to 0.5% and 1.7%, respectively of 860 patients. Repeated operations were performed in 51 (62.2%) patients out of 82 to restore the celiac artery in 28 (34.2%), among them 4 (4.9%) in combination with interventions on the abdominal organs. Abdominal operations with concomitant diseases of the gastrointestinal tract with normal flow in celiac artery in 21 (25.6%).Scalenotomy in two (2.4%). Of 28 patients, re-revascularization of the celiac artery was successful as a result of open decompression in 7 out of 8, bypass surgery in 9 out of 10 and balloon angioplasty and with stenting in two out of 7. One had an effective primary DCA and the other resected PDA aneurysm. 19 patients out of 25 showed a good result after operations on the abdominal organs.Conclusion. The unsatisfactory results of surgical treatment of patients with CASC are associated with inadequate restoration of celiac artery restenosis and/or concomitant diseases of the abdominal organs. Repeated vascular operations are mainly: decompression of celiac artery in open approach, bypass surgery and balloon angioplasty and stenting, and/or abdominal mainly: cholecystectomy, NissenFP, and Strong surgery are of primary importance in the treatment of patients with CASC.

The OBJECTIVE was to study the patency of the internal iliac artery and its effect to gluteus muscles blood supply and frequency of buttock claudication occurrence in the remote period after open infrarenal aortic aneurysm repair. MATERIAL AND METHODS. Examination of 37 patients after open infrarenal aortic aneurysm repair included collection of complaints, anamnesis, making CT scan with contrast and pelvic perfusion tomography. These methods allowed to assess the patency of the prosthesis and iliac arteries, calculate average blood flow rate in buttock muscles and frequency of buttock claudication occurrence depending on the lesion of the internal iliac arteries. RESULTS. Five-year patency of the internal iliac artery was 93 %. In case of passable internal iliac artery, the average blood flow rate in the ipsilateral buttock muscles was authentically higher than the same indicator in groups with stenotic or occlusive lesion of the internal iliac artery and its branches. In case of the disturbed internal iliac artery patency, the frequency of occurrence of the buttock claudication in the same side reached 50 %. CONCLUSION. High five-year internal iliac artery patency after open infrarenal aortic aneurysm repair attested the necessity of preservation the main blood flow in these arteries during the open infrarenal aortic aneurysm repair for the purpose of buttock claudication prevention. The CT scan allowed to evaluate the internal iliac artery patency and the average blood flow rate in the buttock muscles through perfusion tomography method which was necessary for differential diagnosis of the buttock claudication syndrome.

The OBJECTIVE is to assess the patency of the inferior mesenteric artery and internal iliac arteries in the remote period after resection of the aneurysm of the infrarenal aortic segment. MATERIAL AND METHODS. The study included 33 patients who underwent resection of the abdominal aortic aneurysm with reconstruction of the inferior mesenteric artery and (or) internal iliac arteries from 1998 to 2017. All patients were examined with computed tomography scan with contrast to assess the patency of inferior mesenteric artery and internal iliac arteries. RESULTS. Patients were observed from 0.5 to 15 years. Among 30 patients with inferior mesenteric artery implanted into the prosthesis, 23 (76 %) patients had a passable inferior mesenteric artery and 7 patients had an occluded inferior mesenteric artery. The implanted inferior mesenteric artery maintained its patency for 3 years in 100% of cases, from 3 to 5 years – in 86%, after 5 years and more – in 62%. In one patient who underwent reconstruction of the internal iliac artery, thrombosis of the prosthetic-internal iliac shunt was found out in 1.5 years after the operation, without any clinical manifestations. One patient, underwent the reconstruction of the internal iliac artery, was diagnosed with thrombosis of the prosthetic-internal iliac shunt in 1.5 years after the operation, which was not accompanied by clinical manifestations. CONCLUSION. The high remote patency of the inferior mesenteric artery and internal iliac arteries reconstructed during resection of the aneurysm of the infrarenal aortic segment indicates the need for this procedure in order to prevent ischemic disorders of the digestive organs and pelvis.

Relevance. Clarifying the sequence and mutual connection of the median arcuate ligamentum syndrome (MALS) and reflux esophagitis (RE) makes it possible to determine the indications and success of the operation. The objective of the study was to compare the results of the examination and operations in patients with the MALS in combination with RE. Material and methods. 198 patients with MALS were examined and operated. Among them, 85 patients was just with MALS, and decompression of celiac trunk was performed for them. 84 patients had MALS and RE, simultaneously decompression of celiac trunk and Nissen fundoplication were performed for that group of patients. 29 patients had MALS and RE, only decompression of celiac trunk was performed for that group. A comparative analysis of the results of examination and surgical treatment of 85 patients with the MALS and 84 in combination with RE was carried out. The average age of the patients is about 30 years, the female gender prevailed. The feeling of heaviness and abdominal pain due to eating and physical activity, neurovegetative disorders was almost in all patients. Daily or weekly heartburn, regurgitation, vomiting and dysphagia as well as edema, erythema and erosion of the esophageal mucosa were observed mainly in patients with MALS in combination with ER. Results. Significant compression stenosis of the celiac trunk was detected in all patients. After the decompression of the celiac trunk in patients with MALS as well as decompression of the celiac trunk and Nissen fundoplication in patients with MALS in combination with ER, most of them received good clinical results and normalization of anatomical and hemodynamic parameters in celiac trunk. Conclusion. In the combined version of the MALS and RE and the corresponding indications it is expedient to perform decompression of celiac trunk and Nissen fundoplication simultaneously.

OBJECTIVE. According to the analytical data, the acute non-occlusive mesenteric ischemia after infrarenal aortic aneurism repair occurs in 0.2–1 % of cases. This complication is difficult to diagnose and associated with unfavorable prognosis and high mortality. MATERIAL AND METHODS. The retrospective analysis included 112 case histories of patients with infrarenal aortic aneurism repair in the period from 2007 to 2017. RESULTS. During the early postoperative period, 2 patients (1.8 %) had an acute non-occlusive mesenteric ischemia with lethal outcome. In these cases, the complication developed with safety patency of main mesenteric arteries and was followed by developing early multiorgan failure and thrombocytopenia. The autopsy showed generalized atherosclerosis, infarctions of kidneys, spleen and liver, caused by cholesterol crystal embolism of microvascular bed, which was found after histological research. CONCLUSION. The clinical presentation of acute non-occlusive mesenteric ischemia after infrarenal aortic aneurism repair is low-specific. One of the etiological factors of this complication is cholesterol crystal embolism in microvascular bed of visceral arteries

OBJECTIVE. The purpose of this study was to evaluate the methods for preservation the patency of the internal iliac arteries during infrarenal aortic aneurysm resection.MATERIAL AND METHODS. The retrospective review was conducted in 200 patients who had undergone infrarenal aortic aneurysms resection between 1998 and 2017. The group 1 consisted of 8 patients who underwent the antegrade internal iliac arteries flow restoration by bypass or prosthetics. The group 2 consisted of 25 people who did not undergo restorating the patency of these arteries. The results were compared in both groups during the intraand early postoperative period.RESULTS. During the statistical analysis, there were no significant differences in duration of operation postoperative period, blood loss between two groups. Among the patients of the group 2, a transient ischemic colitis developed in one case, a prosthesis thrombosis developed in 5 patients. The complications described above have never been noted in the group 1.CONCLUSION. Direct revascularization of the internal iliac arteries during infrarenal aortic aneurism resection is an important factor of preventing the ischemic disorders of the pelvic organs and the left half of the colon do not significantly affect the volume of blood loss and the duration of the operation and the postoperative period.

Standard methods of diagnostics haven't got a proper sensitivity and specificity concerning assessment of regional nodal involvement in case of rectal cancer. Therefore it is necessary to look for new method of diagnostics, detect risk factors and unfavorable prognosis in relation to lateral lymph node metastasis. At the same time, there should be a differentiated approach to the choice of therapeutic management in rectal cancer. Investigation of variability of blood supply of the rectum could be an additional method of diagnostics in rectal cancer.
