Design and Implementation of a Cloud PACS Architecture.

The limitations of the classic PACS (picture archiving and communication system), such as the backward-compatible DICOM network architecture and poor security and maintenance, are well-known. They are challenged by various existing solutions employing cloud-related patterns and services. However, a full-scale cloud-native PACS has not yet been demonstrated.

One stage onlay hernia repair with abdominoplasty in patients following gastric bypass surgery.

Purpose: 1. Evaluation of results after one-time incisional hernia repair (IHR) modo on-lay and abdominoplasty (Ab-pl) in patients after loss of weight following previous Roux-en-Y Gastric Bypass – RYGB. 2.

Neutrophil-lymphocyte ratio and creatinine reduction ratio predict good early graft function among adult cadaveric donor renal transplant recipients. Single institution series.

Background Delayed graft function (DGF) is a common complication following kidney transplantation and is associated with ischemia-reperfusion injury (IRI). Lymphocytes contribute to the pathogenesis of IRI and ischemia-reperfusion related delayed graft function Materials and Methods 135 Caucasian patients received a kidney graft from deceased heart-beating organ donors. We divided patients into 2 groups- patients with the eGFR>=30 on the 21st day post-transplantation (n=36) and patients with the eGFR<30 on the 21st day post-transplantation (n=99) to assess kidney graft function.

The concentration of D-dimers in portal blood positively correlates with overall survival in patients with non-resectable pancreatic cancer.

Background: Several recent studies provide evidence that D-dimer (DD) concentration in peripheral blood correlates negatively with overall survival (OS) in patients with pancreatic ductal adenocarcinoma (PDAC). Contrarily, there are recent evidence indicating that preoperative plasma fibrinogen, but not D-dimer might represent a prognostic factor in non-metastatic gastrointestinal cancers.

Methods: In a single-center prospective study, we enrolled 62 patients undergoing surgery for pathologically confirmed PDAC without detectable venous thrombosis.

Ruptured Hemangioma of a Native Kidney: An Unusual Cause of Postoperative Hemorrhage in Kidney Transplant Recipients.

BACKGROUND Retroperitoneal bleeding as a consequence of non-traumatic kidney or allograft rupture is well known, but there are no reports on hemorrhagia from a native kidney after allogeneic renal transplantation. Therefore, we present the first such case to be published and highlight the possibility of this complication after renal transplantation. CASE REPORT We report the case of a 28-year-old male patient who developed early post-transplant hemorrhagia from a ruptured native kidney.

Insulinoma--rare, but important clinical problem. Analysis of a series of 530 patients who underwent surgical treatment for the pancreatic tumor.

Unlabelled: Insulinomas are rare tumors, accounting for 1-2% of all neoplasms of the pancreas. Usually their treatment is not associated with any problems; however there is a small subset of problematic clinical cases. The authors present their own clinical experience with surgical treatment of insulinomas of the pancreas.

Preoperative high level of D-dimers predicts unresectability of pancreatic head cancer.

Aim: To assess the value of D-dimer level in determining resectability of pancreatic cancer.

Methods: Preoperative prediction of pancreatic head cancer resectability remains inaccurate. The use of hemostatic factors may be of potential help, since D-dimers correlate with tumor stage.

Gastrojejunostomy in patients with unresectable pancreatic head cancer - the use of Roux loop significantly shortens the hospital length of stay.

Aim: To evaluate the use of the Roux loop on the postoperative course in patients submitted for gastroenteroanastomosis (GE).

Methods: Non-jaundiced patients (n = 41) operated on in the Department of General and Transplant Surgery in Lodz, between January 2010 and December 2011 were enrolled. The tumor was considered unresectable when liver metastases or major vascular involvement were confirmed.

The impact of the repair of staple line dehiscence in post-RYGB patients on glucose homeostasis and gut hormones--a preliminary study.

Introduction: Staple-line disruption (SLD) following Roux-en-Y gastric bypass (RYGB) results in weight regain. This study evaluated glucose homeostasis and gut hormonal changes following surgical repair of gastrogastric fistula.

Material And Methods: Three patients with SLD underwent an oral 75 g glucose tolerance test (OGTT) before (baseline) and one week after gastric pouch restoration.

Personal history of obesity matters. Adolescent adiposity may influence the late results of gastric bypass performed in adults.

Introduction: The influence of adolescent obesity on weight loss following bariatric surgery in adults has not been evaluated. The purpose of this study was to determine the impact of prior adolescent obesity on long-term weight changes following Roux-en-Y gastric bypass (RYGB) in adulthood.

Material And Methods: This single centre retrospective cohort study evaluated changes in body mass index (BMI) after RYGB within 9-13 years.

Very high concentration of D-dimers in portal blood in patients with pancreatic cancer.

Unlabelled: Nowadays, increasing attention has been focused on relation between increased D-dimer levels and cancer among patients without detectable thrombosis. The aim of the study was to measure plasma D-dimer levels in portal and peripheral blood in pancreatic cancer patients with absence of venous thromboembolism.

Material And Methods: Fifteen consecutive patients hospitalized in the Department of General and Transplant Surgery of Medical University in Łódź, from January to March 2012 who underwent surgery due to a pancreatic cancer were enrolled.

CA 125 concentration in portal blood as a predictor of resectability in pancreatic tumor.

Aim Of The Study: Pancreatic cancer is one of the most frequent cancers in the world. Only 20% of patients seem to have disease confined to the pancreas, but in only every second case the tumor turns out to be resectable during surgery. Tumor markers may be a useful tool in differentiating benign from malignant pancreatic tumors and in clinical staging.

Synchronous occurrence of multiple focal nodular hyperplasia and huge hepatic perivascular epithelioid cells tumor (PEComa) in young woman after oral contraceptive use--is there a common pathogenesis?

The association of focal nodular hyperplasia (FNH) and various neoplasms was described, but coincidence of multiple FNH and hepatic perivascular epithelioid cells tumor (PEComa) has not been reported. The clinical debate of oral contraceptive (OC) influence on FNH growth is ongoing, but no evidence exists about association of hepatic PEComa with OC use. Herein, we report a case of two FNH lesions and huge (150x100x80 mm) left hepatic lobe PEComa that occurred simultaneously in 18-year-old female with previous two year history of OC use, who underwent left hemihepatectomy and right hepatic FNH enucleation.

Major liver resection results in early exacerbation of insulin resistance, and may be a risk factor of developing overt diabetes in the future.

Purpose: This single center prospective cohort study evaluated the influence of hemihepatectomy on glucose homeostasis.

Methods: The study included 30 patients undergoing hemihepatectomy. All patients underwent an oral 75 g glucose tolerance test before (baseline), 1 week and 1 month after the surgery.

Sentinel lymph node mapping in tumors of the pancreatic body: preliminary report.

Aim Of The Study: Actual lymphatic drainage of pancreatic body neoplasms and the proper extent of lymphadenectomy remain unknown. The aim of the study was to define the exact lymphatic draining pattern using the dye mapping method.

Material And Methods: The study enrolled patients who were operated on for tumor of the pancreatic body in the Department of General and Transplant Surgery of the Medical University of Lodz during 2010, with injection of 1 ml of blue dye (Patent Blue, Guerbet) in the centre of the neoplasm and sentinel node identification.

[Two-stage liver resections with portal branch ligation--a novel treatment strategy for patients with initially irresectable, bilobar colorectal liver metastases].

Liver resection is the only potentially curative treatment option of patients with colorectal cancer metastases. However, at the time of diagnosis, most patients have irresectable tumors. Preoperative chemotherapy and portal vein embolization may lead to downsizing of initially irresectable colorectal cancer metastases, located in one lobe of the liver.

Students of the Polish catholic theological seminars and the issue of organ transplantation.

Background: The aim of the paper was the analysis of the stance and knowledge of the religious seminars alumni, about the legal foundations of transplantology.

Material/methods: The study group were 204 alumni of the five senior religious seminars in Poland. By the use of an anonymous questionnaire, the clerics were interviewed.

Two-staged surgery for metastatic liver tumor in morbidly obese individual-left hemihepatectomy following placement of laparoscopic adjustable gastric band.

A 47-year-old male with a body mass index (BMI) 37.12 kg/m(2) was diagnosed with an ill-demarcated tumor within IVB segment of left lobe of the liver. Sixteen months earlier, he underwent laparoscopic gastric banding for morbid obesity (BMI 51 kg/m(2)).

Long-term results of gastric bypass surgery in morbidly obese type 1 diabetes patients.

Background: Long-term effects of bariatric surgery in morbidly obese type 1 patients are unknown. Five to eight-year experience in the case series of type 1 diabetes subjects is presented.

Methods: Three poorly controlled type 1 diabetes patients, aged 19, 23, and 28 underwent Roux-en-Y gastric bypass surgery.

Primary perivascular epithelioid cell tumor (PEComa) of the liver: report of a case.

PEComa is very rare mesenchymal neoplasm which is formed by perivascular epithelioid cells and is characterized by dual melanocytic and myoid differentiation. Up to now only a very few cases of PEComa of the liver have been described worldwide. We herein present a patient who underwent a right hemihepatectomy for a huge tumor which could not be identified by imaging investigations.

Predicting maximum Roux-en-Y gastric bypass-induced weight reduction--preoperative plasma leptin or body weight?

Background: Weight loss after bariatric surgery varies between patients, and predicting the extent thereof is often inaccurate. The aim of this study was to assess the potential of preoperative plasma leptin and body weight in predicting the maximum weight loss within 2 years after Roux-en-Y gastric bypass (RYGBP).

Methods: The study comprised 68 subjects (39 women, 29 men; mean age 36.
