The Prevalence of Prostate Cancer in Organ Donors With Increased Prostate-Specific Antigen.

Elevated prostate-specific antigen (PSA) levels were found in 139 of 472 kidney donors from our transplant center tested between 2009 and 2022, representing 29%. The mean age of these donors was 47.3 years. PSA values ranged from 2.8 to 160.4 ng/mL (mean 13.9 ng/mL). The recommended range is <2.5 ng/mL. Prostate histopathologic examination was performed in 38 of the 139 (27%). We found 14 cases of prostate cancer (PCa), with Gleason 3+3 in 8 cases, 3+4 in 4 cases (one donor disqualification), 1 case Gleason 4+3 (donor disqualification), and 1 case Gleason 4+5 (donor disqualification). Thirty-three patients met the criteria, were aged ≥50 years, and had a PSA level >10 mg/mL. Of these, prostate histopathologic examination was performed in 24 cases. PCa was found in 10 cases (42%). There was no difference between donors ≥50 years of age, with PSA>10 ng/mL with and without pathomorphologic diagnosis of PCa regarding age (mean 60.4 vs 60.6 years), creatinine clearance according to the Cockroft-Gaulta formula (mean 101.6 vs 94.8 mL/min) and PSA levels (mean 34.1 vs 29.3 ng/mL). Among other donors with PCa, 3 were <50 years with PSA >10 ng/mL, and 1 was ≥50 years with PSA<8 ng/mL. Kidneys from donors with PCa were transplanted into 10 men and 9 women. Follow-up time was 1 to 10 years. No cases of PCa transmission were reported. One of the recipients died of neoplasm-breast cancer. Donors ≥50 years of age with PSA>10 ng/mL have a higher risk for Pca. Accepting donors with Pca (Gleason 3+3 and 3+4) possesses minimal risk for transmission. All donors ≥50 years with increased PSA require further diagnostic procedures (eg, digital rectal examination, ultrasound, and eventually histologic examination).

Kidney Transplantation in Patients After Bariatric Surgery: High-Volume Bariatric and Transplant Center Experience.

BACKGROUND: Kidney transplantation (KTx) is the best type of treatment for patients with end-stage renal disease (ESRD). Unfortunately, obesity may be a contraindication for transplantation. Our study aimed to evaluate the results of KTx in patients who had bariatric surgery (BS) prior to transplantation. METHODS: A single center, with experience in bariatric and transplant surgery, presents a retrospective study of 13 patients who received a kidney transplant after a gastric bypass (GB) operation between 2012 and 2019. RESULTS: Thirteen patients, who were potential candidates for KTx, were previously qualified for BS because of a body mass index (BMI) > 35 kg/m2. Additionally, all patients had arterial hypertension, 60% of patients had diabetes, and 30% of patients had coronary artery disease. Patients were activated on the waiting list when their BMI was < 35 kg/m2. KTx was performed between 5 and 29 months after BS. One patient needed reoperation due to a urinary leak and another patient needed reoperation because of a high-pressure lymphocele. We diagnosed 2 delayed graft functions (DGFs) and 1 acute rejection. One patient died for reasons independent of surgery. The KTx observation period ranged from 3 to 8 years. Currently, 11 patients has stable renal function: creatinine concentration is 0.8-1.8 mg/dL and BMI is between 23 and 35 kg/m2. CONCLUSIONS: Despite the small group of patients, we can assume that kidney transplantation can be safely performed in patients with end-stage renal disease (ESRD) who have previously undergone gastric bypass (GB) as a graft bridging procedure. In some cases, BS may be the only chance of getting an organ.

Kidney stones are common in patients with short-bowel syndrome receiving long-term parenteral nutrition: A predictive model for urolithiasis.

BACKGROUND: In short-bowel syndrome (SBS) treated with parenteral nutrition (PN), multiple complications can occur. The etiology of kidney stones may be linked to the underlying disease thrombosis, surgical complications, complications of therapy for cancer, Crohn's disease, metabolic abnormalities resulting from morphological and functional changes in the gastrointestinal tract, and to treatment used. We analyzed all these parameters in a large cohort of patients receiving home PN (HPN), to define the incidence of stones and groups of patients particularly at risk of stone formation. One of the objectiveswas to develop a predictive model of urolithiasis. METHODS: This observational retrospective study included 459 patients with SBS recieving HPN in a single center. Patient records were evaluated for demographics, SBS etiology, and underlying disease, anatomy of the gastrointestinal tract, intestinal failure classification, nutrition regimen, and presence of urolithiasis. RESULTS: Kidney stones were diagnosed in 24% of patients. Nodifferences in incidence were noted between the various etiologic groups. The incidence in patients with a colon in continuity and those with an end stoma was similar. The length of residual small bowel did not play a role in stone formation. There were no differences between patients according to the severity of intestinal failure. In patients treated with PN and limited oral feeding, the risk of urolithiasis was twice as high as in patients receiving PN only. CONCLUSIONS: Patients developed urolithiasis with no relation to the SBS etiology. The risk of kidney stone formation was higher in patients recieving PN with oral feeding.

Minimally Invasive Treatment of Vesico-ureteral Reflux Using Endoscopic Injection of Polyacrylate-Polyalcohol Copolymer (Vantris) in Patients After Kidney Transplantation.

BACKGROUND: Urinary tract infections (UTIs) are the most common infectious complications among kidney recipients. They occur due to the lack of an effective antireflux mechanism in the majority of techniques used during kidney transplantation. Subureteral injection of tissue bulking substance is a feasible alternative to open ureteral reimplantation. This paper, to the best of the authors' knowledge, is the first to evaluate the application of polyacrylate/polyalcohol copolymer (Vantris) as the agent for minimally invasive VUR treatment. MATERIALS AND METHODS: Between January 2018 and February 2019, 7 patients presenting with recurrent UTIs and the diagnosis of VUR (vesico-ureteric reflux) after kidney transplantation were enrolled in the study. Patients qualified for the study underwent cystoscopy and, if possible, minimally invasive, endoscopic subureteral application of 1 mL of polyacrylate/polyalcohol copolymer according to the subureteral transurethral injection (STING) technique. RESULTS: Endoscopic subureteral injection of tissue bulking substance (polyacrylate/polyalcohol copolymer) was successfully performed in 6 patients. In 1 patient it could not be completed because of an inconvenient location of the neo-orifice. In 4 patients (57%) no reduction of the reflux grade was observed in follow-up imaging. The number of UTIs in the follow-up was significantly reduced in 6 of 7 patients (86%) after polyacrylate/polyalcohol copolymer subureteral injection. CONCLUSIONS: Endoscopic treatment of VUR with polyacrylate/polyalcohol copolymer is an effective and safe method as a first-line treatment for patients with recurrent UTIs after kidney transplantation. To obtain clear conclusions, however, it is necessary to study a larger number of patients with a longer follow-up period after surgery.

Cost-effectiveness of benign Wirsung duct strictures treatment in chronic pancreatitis.

INTRODUCTION: Chronic pancreatitis (CP) is an important problem for modern medicine, the healthcare system (Poland - NFZ) and the national insurance system (Poland - ZUS). The chronic nature of the disease, the lack of targeted treatment and the low mortality rate lead to an accumulation of patients who demand expensive treatment, both conservative and invasive. Rising costs in health care are forcing the need for a more cost-effective method of treatment. AIM: The primary aim of this study was to perform a retrospective calculation of costs in both surgical and endoscopic treatment, hospital stay, healthcare, and public insurance of patients suffering from chronic pancreatitis. Parallel quality of life analysis was performed. It was possible to develop a cost-effective therapeutic algorithm for patients with an uncomplicated stricture of Wirsung's duct within the Polish health care system. RESULTS: In Poland, the hospital costs of endoscopic treatment of patients with chronic pancreatitis were higher than those of the surgical treatment group despite both resulting in a similar life quality. CONCLUSIONS: From a cost-effectiveness perspective, it was shown that surgical intervention is a more cost-effective therapy than endotherapy. Furthermore, patients with benign stricture of the main pancreatic duct in chronic pancreatitis should not be treated with endotherapy for longer than 12 months.

Surgical decompression of Wirsung duct reduces serum concentration of SPINK1 in patients with chronic pancreatitis.

OBJECTIVES: The primary aim of this study was to determine the blood levels of SPINK1 in patients with chronic pancreatitis (CP) submitted to surgical or endoscopic decompression of pancreatic duct (PD). Additionally, we measured trypsin activity levels. METHODS: Two groups were identified, surgical (group A) and endoscopic (group B). Levels of SPINK1 and trypsin activity were measured at baseline and 6 months after pancreatic duct decompression and then compared within the groups. SPINK1 levels were determined with Human ELISA Kit. RESULTS: Group A and B were made up of 30 and 28 patients, respectively. Baseline features of the groups were similar. A decrease in SPINK1 levels was significant only in group A 46.88 to 16.10 ng/mL (p = 0.001). On the contrary, trypsin activity changed significantly in group B 40.01 to 34.92 mU/mL (p = 0.01). Patients of group A showed a significant increase in BMI, before and after treatment. The pain score pre- and post-treatment reduced significantly in both groups (p < 0.001). CONCLUSIONS: We demonstrate for the first time a significant decrease of SPINK1 levels after surgical decompression of PD and a reduction of trypsin activity analysis after endoscopic decompression. The meaning of this phenomena is yet to be explained and it should be further explored.

Strategies for early metabolic disturbances in patients with an end jejunostomy or end ileostomy. Experience from a specialized Home Parenteral Nutrition (HPN) center.

INTRODUCTION: An end stoma syndrome is usually the result of an intentional surgical intervention in the course of staged treatment or a complication of surgery. These patients most frequently suffer from water and electrolyte disturbances, malnutrition syndromes caused by malabsorption of trace elements and/or vitamins, and undernutrition. AIM: To present early metabolic disturbances observed in patients with an end jejunostomy or end ileostomy syndrome on the first day of their hospitalization in a specialist Home Parenteral Nutrition (HPN) center. MATERIAL AND METHODS: The study included 142 patients with an end stoma syndrome (76 women and 66 men), hospitalized between 2004 and 2014. Patients were divided into two main groups. Group A consisted of 90 patients with an end jejunostomy and group B consisted of 52 patients with an end ileostomy. RESULTS: After comparing the patients with an end jejunostomy vs. those with an end ileostomy, significant differences were found as regards pH (7.34 vs. 7.39, p = 0.043) and BE (3.24 vs. -0.86, p = 0.005). Depending on the lack or possibility of oral food intake, patients in the end jejunostomy group had different levels of the markers phosphate, Mg, Ca, urea, and creatinine, with all of these parameters within normal laboratory limits. When the end ileostomy group was divided into subgroups depending on the lack or possibility of oral food intake, differences in C-reactive protein activity were found (55.6 vs. 25.7, p = 0.041). CONCLUSIONS: Patients with an end jejunostomy syndrome are more prone to metabolic acidosis with significant alkali deficiencies.

A comparison of two methods of treatment for central catheter tunnel phlegmon in home parenteral nutrition patients.

INTRODUCTION: The ESPEN guidelines on long-term (> 3 months) parenteral nutrition recommend the use of tunnelled central venous catheters (CVCs) to minimise the risk of insertion site infection. A developed symptomatic infection of the soft tissue tunnel surrounding a CVC may rapidly become directly life threatening if the infection progresses along the catheter tunnel towards its end inserted into the venous system. This requires immediate management to eliminate infection and limit its effects. AIM: To compare two surgical techniques for the treatment of suppurative inflammation of a CVC tunnel: conventional drainage of the infected tissues (surgical technique A) vs. radical en bloc excision of the infected tissues together with the infected central catheter (surgical technique B). MATERIAL AND METHODS: Seventy-three patients hospitalised due to CVC tunnel phlegmon between April 2004 and May 2014 were included in the retrospective study. Thirty-four (46.5%) patients underwent surgical procedure A and another 39 (53.5%) underwent procedure B. RESULTS: The mean duration of antibiotic therapy following procedure A was 8 ±3 days, whereas procedure B required 7 ±2 days of antibiotic therapy (NS). The mean hospitalisation period following procedure B was over 8 days shorter in comparison to that following procedure A (16.54 ±7.59 vs. 24.87 ±10.19, p = 0.009, respectively). CONCLUSIONS: The surgical treatment of CVC tunnel phlegmon involving radical en bloc excision of suppurated tissues along with the infected CVC shortens hospitalisation, expedites the insertion of a new CVC, and potentially reduces treatment costs.

Perfusion-CT--Can We Predict Acute Pancreatitis Outcome within the First 24 Hours from the Onset of Symptoms?

PURPOSE: Severe acute pancreatitis (AP) is still a significant clinical problem which is associated with a highly mortality. The aim of this study was the evaluation of prognostic value of CT regional perfusion measurement performed on the first day of onset of symptoms of AP, in assessing the risk of developing severe form of acute pancreatitis. MATERIAL AND METHODS: 79 patients with clinical symptoms and biochemical criteria indicative of acute pancreatitis (acute upper abdominal pain, elevated levels of serum amylase and lipase) underwent perfusion CT within 24 hours after onset of symptoms. The follow-up examinations were performed after 4-6 days to detect progression of the disease. Perfusion parameters were compared in 41 people who developed severe form of AP (pancreatic and/or peripancreatic tissue necrosis) with parameters in 38 consecutive patients in whom course of AP was mild. Blood flow, blood volume, mean transit time and permeability surface area product were calculated in the three anatomic pancreatic subdivisions (head, body and tail). At the same time the patient's clinical status was assessed by APACHE II score and laboratory parameters such as CRP, serum lipase and amylase, AST, ALT, GGT, ALP and bilirubin were compared. RESULTS: Statistical differences in the perfusion parameters between the group of patients with mild and severe AP were shown. Blood flow, blood volume and mean transit time were significantly lower and permeability surface area product was significantly higher in patients who develop severe acute pancreatitis and presence of pancreatic and/or peripancreatic necrosis due to pancreatic ischemia. There were no statistically significant differences between the two groups in terms of evaluated on admission severity of pancreatitis assessed using APACHE II score and laboratory tests. CONCLUSIONS: CT perfusion is a very useful indicator for prediction and selection patients in early stages of acute pancreatitis who are at risk of developing pancreatic and/or peripancreatic necrosis already on the first day of the onset of symptoms and can be used for treatment planning and monitoring of therapy of acute pancreatitis. Early suspicion of possible pancreatic necrosis both on the basis of scores based on clinical status and laboratory tests have low predictive value.

Cholecystectomy after breast reconstruction with a pedicled autologous tram flap. Types of surgical access.

The number of breast reconstruction procedures has been increasing in recent years. One of the suggested treatment methods is breast reconstruction with a pedicled skin and muscle TRAM flap (transverse rectus abdominis muscle - TRAM). Surgical incisions performed during a cholecystectomy procedure may be located in the areas significant for flap survival. The aim of this paper is to present anatomical changes in abdominal walls secondary to pedicled skin and muscle (TRAM) flap breast reconstruction, which influence the planned access in cholecystectomy procedures. The authors present 2 cases of cholecystectomy performed due to cholelithiasis in female patients with a history of TRAM flap breast reconstruction procedures. The first patient underwent a traditional method of surgery 14 days after the reconstruction due to acute cholecystitis. The second patient underwent a laparoscopy due to cholelithiasis 7 years after the TRAM procedure. In both cases an abdominal ultrasound scan was performed prior to the operation, and surgical access was determined following consultation with a plastic surgeon. The patient who had undergone traditional cholecystectomy developed an infection of the postoperative wound. The wound was treated with antibiotics, vacuum therapy and skin grafting. After 7 weeks complete postoperative wound healing and correct healing of the TRAM flap were achieved. The patient who had undergone laparoscopy was discharged home on the second postoperative day without any complications. In order to plan a safe surgical access, it is necessary to know the changes in the anatomy of abdominal walls following a pedicled TRAM flap breast reconstruction procedure.

Mucinous cystadenocarcinomas of the pancreas.

BACKGROUND/AIMS: The purpose of this study was to evaluate the clinicopathologic characteristics, diagnosis and treatment of mucinous cystadenocarcinomas (MCACs) of the pancreas. METHODOLOGY: This is a retrospective review of 6 patients who underwent curative resection for MCACs of the pancreas in the Department of General Endocrine and Transplantation Surgery, Medical University of Gdansk from 1994-2004. Clinical presentation, radiological evaluation and surgical procedures were analyzed. RESULTS: There were 4 women and 2 men. Median age was 59 years. Patients complained of abdominal pain, nausea, vomiting and weigh loss, 2 of them had jaundice and 1 gastrointestinal (GI) bleeding. Ultrasonography and computed tomography showed cystic lesions. Solid component was found in 3 cases. Three endoscopic retrograde cholangiopancreatographys (ERCPs) were unhelpful in differentiating between malignant tumor and benign lesion. All patients underwent resection. In 3 cases Whipple resection, in 1 case Traverso - Longmire resection and in 2 cases distal pancreatectomy was performed. Histopathologically, all tumors were mucinous cystadenocarcinomas. CONCLUSIONS: Diagnostic accuracy for cystic pancreatic neoplasm is still limited. Surgical resection is recommended in all cystic tumors that are not clearly defined.

Results of pancreaticogastrostomy after pancreaticoduodenectomy in 159 consecutive cases.

BACKGROUND: Pancreaticogastrostomy has been known as a method of reconstruction after pancreaticoduodenectomy for almost 60 years. According to some published reports, the pancreatic fistula rate for pancreaticogastrostomy is low. The purpose of this study is to present the results of pancreaticogastrostomy after pancreaticoduodenectomy at one department of our university hospital. METHODS: From 1994 to 2004, 159 patients underwent pancreaticoduodenectomy. Whipple procedures were performed in 125 cases and 34 underwent pylorus-preserving modification. In all of them, pancreaticogastrostomy was the method of choice for pancreatic-enteric anastomosis. The main outcome measures were postoperative morbidity and mortality. RESULTS: There were 56 patients (35%) who developed postoperative complications. 20 of them were reoperated due to pancreatic fistula (4), pancreatic fistula and biliary stenosis (1), biliary leak (2), enteric anastomosis leak (1), hemorrhage from the pancreaticogastric anastomosis (6), intra-abdominal bleeding (2), abdominal abscess (2) and evisceration (2). The other 36 patients were managed conservatively. The appearance of pancreatic fistulas had a statistically significant influence on the duration of hospitalization only. Six patients (3.7%) died. Two of them had pancreatic fistula. CONCLUSION: We recommend pancreaticogastrostomy as a simple and safe method of reconstruction after pancreatico- duodenectomy with low mortality and morbidity rates. and IAP.

Hemorrhage from ruptured hepatic artery pseudoaneurysm co-occurring with pancreatic head tumor and portal vein thrombosis: surgical and endovascular treatment.

We report a case of 50-year-old man with a hepatic artery pseudoaneurysm, pancreatic head tumor, and portal vein thrombosis. The patient was operated on due to acute bleeding into duodenum. The pancreatic tumor was unresectable, which is why the ruptured pseudoaneurysm was only sutured. The second therapeutic step was to protect the hepatic artery against rupture. Therefore, a stent graft and then a wall graft endoprosthesis were placed across the pseudoaneurysm neck. The final angiogram demonstrated total exclusion of the pseudoaneurysm with preservation of the arterial lumen.

[Difficulties in diagnostics in recurrent abdominal pains in 71-years-old patient]. / Trudnosci diagnostyczne w nawracajacych bólach brzucha u 71-letniej chorej.

Neoplasm of B-cell origin is the most frequent malignant disease of the lymphatic tissue. It is usually presented as enlargement of lymph nodes, hepatosplenomegaly, skeletal pains and gastrointestinal dysfunction. Splenic lymphoma can cause the difficulties in diagnostic procedures (ultrasound and computed tomography). It may be nearly anechoic and mimic a cyst, abscess or parasitic mass. We describe a course of the disease and diagnostic troubles noted in 71-years-old patient, in whom splenic cysts enlarging rapidly were observed. Splenectomy due to presented difficulties in diagnosis such as clinical disquiet about subsequent course of the disease was performed. It let us to recognize malignant lymphoma and initiate a correct treatment strategy.
