Abstract
Rationale and objectives Intraductal papillary mucinous neoplasm of the bile ducts (IPMN-B) is a true pre-cancerous lesion, which shares common features with pancreatic IPMN (IPMN-P). While IPMN-P is a well described entity for which guidelines were formulated and revised, IPMN-B is a poorly described entity.We carried out a systematic review to evaluate the existing literature, emphasizing the role of MRI in IPMN-B depiction. Materials and methods PubMed database was used to identify original studies and case series that reported MR Imaging features of IPMN-B. The search keywords were "IPMN OR intraductal papillary mucinous neoplasm OR IPNB OR intraductal papillary neoplasm of the bile duct AND Biliary OR biliary cancer OR hepatic cystic lesions". Risk of bias and applicability were evaluated using the QUADAS-2 tool. Results 884 Records were Identified through database searching. 12 studies satisfied the inclusion criteria, resulting in MR features of 288 patients. All the studies were retrospective. Classic features of IPMN-B are under-described. Few studies note worrisome features, concerning for an underlying malignancy. 50 % of the studies had a high risk of bias and concerns regarding applicability. Conclusions The MRI features of IPMN-B are not well elaborated and need to be further studied. Worrisome features and guidelines regarding reporting the imaging findings should be established and published. Radiologists should be aware of IPMN-B, since malignancy diagnosis in an early stage will yield improved prognosis.

Abstract
OBJECTIVE The few studies on the association between benign ovarian tumors and endometrial cancer have been inconclusive. Using data from a large Danish register-based cohort study, we assessed the overall and type-specific risk of endometrial cancer among women with a benign ovarian tumor. METHODS We identified all Danish women diagnosed with a benign ovarian tumor during 1978-2016 in the Danish National Patient Register (n = 149,807). The study population was followed for subsequent development of endometrial cancer by linkage to the Danish Cancer Register and standardized incidence ratios (SIRs) with corresponding 95% confidence intervals (CIs) were calculated after correction for hysterectomy. RESULTS After a one-year delayed study entry, women with benign ovarian tumors had a decreased incidence of endometrial cancer (SIR = 0.74, 95% CI: 0.68-0.81) compared with women in the general Danish population. Both solid benign ovarian tumors (SIR = 0.79, 95% CI 0.70-0.88) and cystic benign ovarian tumors (SIR = 0.68, 95% CI 0.58-0.78) were associated with decreased incidences of endometrial cancer. Likewise, women with benign ovarian tumors had decreased incidences of both type I and type II endometrial cancer. The incidence of endometrial cancer was decreased to virtually the same magnitude irrespective of the age at diagnosis of a benign ovarian tumor and the reduction persisted throughout the follow-up period. CONCLUSIONS The risk of endometrial cancer was decreased beyond the first year after a benign ovarian tumor and the decrease persisted for 20 or more years. The possible underlying mechanisms are not known and should be investigated further.

Abstract
PURPOSE The purpose of the study was to evaluate the efficacy and safety of percutaneous drainage for palliation of symptoms and sepsis in patients with cystic or necrotic tumors in the abdomen and pelvis. MATERIALS AND METHODS This is a single center retrospective study of 36 patients (18 men, mean age = 51.1 years) who underwent percutaneous drainage for management of cystic or necrotic tumors in the non-postoperative setting over an 11-year period. Nineteen patients with intraabdominal fluid collections associated with primary malignancies included: cervical (n = 7), colorectal (n = 3), urothelial (n = 3), and others (n = 6). The 17 patients with fluid collections associated with intraabdominal metastases stemmed from the following primary malignancies: oropharyngeal squamous cell carcinoma (n = 3), colorectal (n = 3), ovarian (n = 2), lung (n = 2), melanoma (n = 2) along with others (n = 5). Indications for percutaneous drainage were as follows: pain (36/36; 100%); fever and/or leukocytosis (34/36; 94%), and mass effect (21/36; 58%). Seven patients underwent additional sclerosis with absolute alcohol. Criteria for drainage success were temporary or definitive relief of symptoms and sepsis control. RESULTS Successful sepsis control was achieved in all patients with sepsis (34/34; 100%) and 30/36 (83%) patients had improvement in pain. Duration of catheterization ranged from 2 to 90 days (mean = 22 days). There were four cases of fluid re-accumulation and one patient developed catheter tract seeding. Alcohol ablation was successful in two patients (2/7; 29%). Nearly all patients (34/36; 94%) died during the follow-up period. CONCLUSIONS Percutaneous drainage was effective for palliative treatment of symptomatic cystic and necrotic tumors in the majority of patients in this series.

Abstract
BACKGROUND It is clear that specific intestinal bacteria are involved in the development of different premalignant conditions along the gastrointestinal tract. An analysis of the microbial constituents in the context of pancreatic cystic lesions has, however, as yet not been performed. This consideration prompted us to explore whether endoscopically obtained pancreatic cyst fluids (PCF) contain bacterial DNA and to determine the genera of bacteria present in such material. METHODS Total DNA was isolated from 69 PCF samples. Bacterial 16S rRNA gene-specific PCR was performed followed by Sanger sequencing and de novo deep sequencing for the V3-V4 variable region of 16S rRNA gene. RESULTS We observed that 98.2% of the samples were positive in conventional PCR, and that 100% of selected PCF samples (n = 33) were positive for bacterial microbiota as determined by next generation sequencing (NGS). Comprehensive NGS data analysis of PCF showed the presence of 408 genera of bacteria, of which 17 bacterial genera were uniquely abundant to PCF, when compared to the Human Microbiome Project (HMP) database and 15 bacterial microbiota were uniquely abundant in HMP only. Bacteroides spp., Escherichia/Shigella spp., and Acidaminococcus spp. which were predominant in PCF, while also a substantial Staphylococcus spp. and Fusobacterium spp. component was detected. CONCLUSION These results reveal and characterize an apparently specific bacterial ecosystem in pancreatic cyst fluid samples and may reflect the local microbiota in the pancreas. Some taxa with potential deleterious functions are present in the bacterial abundance profiles, suggesting that the unique microbiome in this specific niche may contribute to neoplastic processes in the pancreas. Further studies are needed to explore the intricate relationship between pathophysiological status in the host pancreas and its microbiota.

Abstract
BACKGROUND The indications for resection of pancreatic cystic lesions (PCL) are often complex and the operative risk has to be balanced against the risk of malignant transformation. The aim of the study was to provide a synopsis of the current treatment results of minimally invasive surgery for PCL. METHODS A systematic literature search was performed using the Medline database (PubMed). Subsequently, the retrieved literature was selectively reviewed. RESULTS No published prospective randomized controlled trials have yet addressed the comparison of open and minimally invasive surgery of PCL; however, retrospective case studies have demonstrated the feasibility, safety and a comparable morbidity after minimally invasive distal pancreatectomy (DP), pancreatoduodenectomy (PD), central (CP) or total pancreatectomy and enucleation. Whereas most DPs are performed laparoscopically, the experience of minimally invasive PD has been consolidated for the robot-assisted approach but is concentrated in only a few centers. The number of published reports on minimally invasive organ-sparing pancreas procedures (e. g. CP or enucleation) for PCL is scarce; however, the available (selected) results are promising. CONCLUSION Minimally invasive surgery for PCL has the potential to reduce the operative trauma to the patients, while at the same time causing comparable or less morbidity. This requires an increasing specialization of complex minimally invasive resections. The clinical use of robotic systems will grow for the latter cases. A prospective registry of the results should be mandatory for quality management.

Abstract
INTRODUCTION Isolated retroperitoneal cysts are uncommon with an estimated incidence of 1/5750-1/250,000. In women they occur about 1.5-2 times more often than in men. The largest numbers of patients are young or middle aged (20-50 years). Lack of knowledge about the causes of these rare entities and asymptomatic clinical picture often leads to diagnostic and tactical mistakes. METHODS The medical history of 54-year old male patient B., who has been hospitalized at Surgical Department №1 of Danylo Halytsky Lviv National Medical University (Surgical Department of Lviv Regional Clinical Hospital), was processed retrospectively. RESULT Diagnosing of retroperitoneal organized hematoma in the early stages is not always possible, because exploration of retroperitoneal space can be difficult. General tests and tumor markers are usually normal range and not prognostically informative in this case. Decisively important were imaging diagnostic methods-USG and CT. As clinical cases of organized hematoma are quite rare, finding out retroperitoneal formation with irregular contours and infiltrative component indicates for retroperitoneal tumors. Thus, this formation accumulated contrast that says for increased vascularization. Intraoperative: formation with thick walls and heterogeneous structure. Histological diagnosis: hematoma in a phase of deep organization. On our opinion, taking into account location and structure of tumors, laparoscopic intervention was not appropriate, open surgery was reasonable approach. Preoperative biopsy has a crucial role to set preliminary diagnosis. CONCLUSION Despite the fact that organized retroperitoneal hematomas are quite rare, their diagnosis requires detailed examination and histological verification.

Abstract
Mixed epithelial and stromal tumour of the kidney (MESTK), is a rare kidney tumour. About 100 cases so far have been reported in the literature. Although MESTK mostly presents in perimenopausal age group some rare cases in young females have been reported. We report a rare presentation of a 25 cm size giant MESTK arising from the left kidney in a young female in the absence of any clinically detectable hormonal abnormalities and successfully managed by nephron-sparing surgery.
