Polyps of the gall-bladder has long been a serious diagnostic problem. Their detection in routine ultrasound is not yet satisfactory and often does not allow you to select the proper method of operating the gall-bladder. The aim of the study was to assess the accuracy of ultrasound diagnosis of polypoid lesions of the gall-bladder through its verification by histopathology in patients treated with cholecystectomy. Material and methods. In the years 2010-2013, 1196 patients underwent surgery due to diseases of the gall-bladder at the Department of General and Transplant Surgery, Medical University in Łódź. The study evaluated the sensitivity of ultrasound in detecting polyps of the gallbladder and histopathological findings of the formulations investigated. Results. Preoperative ultrasound examination (USG) revealed a polypoid lesion in 64 patients; only in 29 of them (44.6%) this diagnosis was confirmed by histopathological examination. In the other cases, cholecystolithiasis or inflammatory lesions were found. The most common histopathological findings included cholesterol polyps, adenomatous polyps, and inflammatory polyps. Malignant lesions (gall-bladder cancer) were found in five patients preoperatively diagnosed with a polypoid lesion, i.e 7.8% of patients preoperatively diagnosed with a polyp and 0.4% of all patients who received surgical treatment. Patients qualified for surgery due to polyps diagnosed by means of ultrasound examination constitued 5.4% of all patients who underwent cholecystectomy. On histopathological examination, the presence of polyps was confirmed in 2.4% patients treated with excision of the gall-bladder. Conclusions. Detection of gall-bladder polyp on ultrasound examination is an indication for cholecystectomy, in particular when the polyp diameter exceeds 10 mm. In each case of a polyp, cholecystolithiasis should also be taken into account and the presence (or absence) of indications for cholecystectomy should be discussed with the patient

Pancreatic cancer is one of the most common malignant diseases in the world. Morbidity rate increases and now reaches around 200 000 new cases yearly. Poor prognosis mainly results from usually late diagnosis and non-specific symptoms. Despite of advances in radiological diagnosis of pancreatic diseases, differentiation between malignant and inflammatory pancreatic tumors still remains difficult. The aim of the studywas the assessment of clinical utility of CA 19-9 in peripheral and portal blood of patients with pancreatic tumor. Material and methods.66 patients were hospitalized at the Department of General and Transplant Surgery between October 2010 nad July 2012 due to pancreatic tumor. Blood samples were collected from peripheral vein before surgery and intraoperatively from the portal vein to measure CA 19-9 concentration. 57 patients were diagnosed with malignant tumor and 9 with inflammatory lesion. Metastases to the liver were present in 7 of all patients. Radical surgery (Whipple’s procedure in 27 cases) were performed in 34 patients. Results.Significantly higher CA 19-9 concentration in the peripheral blood and in the portal blood as well was found in the pancreatic cancer group than in the inflammatory lesions group (51.2 vs <3 and 52.1 vs 6.3 respectively). Marker concentration in case of malignant lesions was significantly higher in the portal blood than in the peripheral blood (52.1 vs 51.2; p<0.05). CA 19-9 concentration of patients with malignant pancreatic tumors but without metastases to the liver was significanlty higher in the portal blood than in the peripheral blood (19.32 vs 18.65; p<0.01). Conclusions.Determination of the CA 19-9 concentration not only in the peripheral blood but in the portal blood as well might be a useful diagnostic tool in order to differentiate between the malignant and inflammatory pancreatic tumors. We did not see any statistically significant dependency between the CA 19-9 concentrations in the peripheral blood and portal blood and if the surgery was radical or not, but significantly higher concentrations of CA 19-9 in the portal blood than the peripheral blood among the patients suffering from the malignant pancreatic tumor without metastases to the liver might be useful tool when decisions on performing pancreatoduodenectomy are being made since this surgery is forborne from when metastases are present.

The aim of the study was to determine whether patients treated with anticoagulants in the perioperative period are at higher risk of developing bleeding complications. Material and methods. Medical records of patients operated for abdominal hernia were analysed. Data concerning demographic characteristic of a group, type of hernia, comorbidities, preoperative anticoagulation therapy and complications were collected. Association of applied anticoagulation therapy with the time of drainage, the amount of drained discharge and the length of hospitalisation was evaluated. Results. Analysed group consisted of 186 patients. Thirty seven patients were treated with different schemes of anticoagulant therapy before the the surgery. Patients treated with triple anticoagulation therapy (acetylsalicylic acid, low-molecular weight heparin, vitamin K antagonists) had significantly longer time of drainage in comparison to patients treated according to other schemes (p<0.05). The amount of drained discharge and time of hospitalisation did not differ significantly. Neither comorbidities nor the administration of low-molecular weight heparin did not affect the analysed parameters. Conclusions. Patients operated on abdominal hernia, who were treated with triple anticoagulation therapy in peri-operative period, require significantly longer drainage of the wound what can result in prolonged hospitalisation

Acute pancreatitis is a disease with significant mortality. Hypertriglyceridemia (HTG) is the third most common etiological factor of this disorder after alcohol and gall-stones. The authors presented a case of 42-years old caucasian female who was hospitalized due to recurrence of acute pancreatitis. She had been diagnosed with HTG. She had earlier seven episodes of acute pancreatitis. Endoscopic papillotomy and conservatory treatment didn’t change her complaints and she was consented for surgery. Exclusion of distal part of bile duct was performed. The common bile duct was anastomosed side-to-side to the 70 cm long Roux loop of the jejunum with the ligation of the distal part of the common bile duct. Following the surgery authors observed normalization of amylase, lipase, leukocytosis and CRP levels. During six months after procedure patient didn’t have any new episode of pancreatitis. Exclusion of distal part of bile duct may be a useful tool in surgical treatment of recurrent acute hypertriglyceridemia-induced pancreatitis.

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. Up to date, the patient has been followed-up for 65 months and remained disease-free. FNH and PEComa have a common vascular cytogenetic denominator. Our case raising a question of a causal relationship of FNH and PEComa with OC use that might be attributed to vascular changes. Future researches of larger sample sizes should further address this issue.

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. The aim of the study was to conduct a retrospective analysis of patients with insulinomas of the pancreas who underwent surgical treatment at Department of General and Transplant Surgery Medical University in Łódź. Material and methods. The study included all patients who underwent surgical treatment at the Department between 2007 and 2013 for the tumor of the pancreas. Further retrospective analysis included all patients with tumors of the insulinoma type. The data was obtained from medical records, surgical protocols and histopathology reports. Results. The analysis included 530 patients who underwent surgical treatment for the tumor of the pancreas. Insulinoma was found in 10 (1.88%) patients (8 females, 2 males). An average age of patients who underwent surgical treatment was 47.5±13.8 years. An average size of the tumor was 1.6±0.5 cm. Six patients underwent extirpation of the insulinoma, while the other patients underwent distal resection of the pancreas. All patients underwent “an open surgical procedure”. The average duration of the surgical procedure was 55±45 minutes. Duration of the hospitalization in the analyzed group of patients was 7±5 days. Incidence of postoperative pancreatic fistulas was 10%. All insulinomas were benign. Conclusions. Insulinomas were rare among patients who underwent surgical treatment at the Department. They were benign and their treatment was unproblematic. However, there is a small group of cases that can be associated with problematic clinical situations. Thus treatment of patients with insulinomas should be conducted at specialist centers. Correct diagnostic and therapeutic management, involving close cooperation between multiple medical specialists, results in complete curing of majority of patients.

Nowadays, increasing attention has been focused on relation between increased D-dimer levels and cancer among patients without detectable thrombosis. 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. At laparotomy, portal and peripheral blood were sampled concurrently. D-dimer and fibrinogen levels were measured. Moreover, to investigate overall coagulation function prothrombin time (PT), prothrombin index (PI), international normalized ratio (INR), thrombin time (TT), activated partial thromboplastin time (APTT), TT and APTT index were evaluated. Results. Peripheral plasma D-dimmer levels above normal range were found in 10/15 patients (66,67%), whereas D-dimer above normal values were confirmed in all portal blood samples. Mean D-dimer values were higher in portal than in peripheral blood (3279.37 vs 824.64, by 297%, p=0,025). These discrepancies were accompanied by normal limits of portal and peripheral levels of fibrinogen and comparable coagulation function indexes. Conclusion. Our preliminary study showed the close relation between activation of hemostasis, reflected by elevated D-dimers in portal blood and presence of pancreatic cancer. These data suggest that measurement of portal blood D-dimer levels may be a potentially useful technique for screening the pancreatic cancer.

Gastroenteropancreatic neuroendocrine tumors (GEP NET) represent heterogenous group of very rare neoplasms. Nevertheless, these tumors have been increasingly diagnosed recently. Authors present own experience with surgical treatment of gastrointestinal neuroendocrine tumors.The aim of the study was to analyse retrospectively own material of patients with gastrointestinal neuroendocrine tumors treated surgically in the Department of General and Transplant Surgery of Medical University in Łódź.Material and methods. The analysis included all patients with neuroendocrine tumors surgically treated from January 2007 to June 2009 in the Department of General and Transplant Surgery of Medical University in Łódź. The clinical patients data were obtained from medical histories, operative protocols and outcomes of final histopathological examinations. Analyzed data were as follows: age, gender, type and localization of tumor, clinical signs, results of preoperative tests and type of surgical procedure.Results. Analysis revealed that 17 patients were operated on for gastrointestinal neuroendocrine tumors between years 2007-2009 in the Department of General and Transplant Surgery. Foregut tumors (5 gastric neuroendocrine tumors and 4 pancreatic insulinomas), midgut tumors (1 neuroendocrine cancer of ascending colon, 3 hepatic neuroendocrine cancers metastases, 2 primary hepatic neuroendocrine cancers, 1 gall bladder neuroendocrine cancer) and hindgut tumors (neuroendocrine cancer of rectum) were diagnosed in nine cases (53%), in seven cases (41%) and in one case (5%), respectively. Wide range of surgeries were performed in the Department, as follows: in 2 cases right hemihepatectomy, in 3 cases extended right hemihepatectomy, in 1 case left hemihepatectomy, in 4 cases pancreatic tumor enucleation, in 2 cases gastric resection, in 3 cases gastrectomy, in 1 case right hemicolectomy and in 1 case anterior resection of the rectum. The vast majority (11/17 patients; 64%) of tumors were poorly-differentiated neuroencorine carcinomas with high grade of histological malignancy. In one case coincidence of insulinoma and nesidioblastosis was confirmed. One patient suffered from signs of neuroglycopenia with loss of consciousness and convulsion preoperatively, incorrectly diagnosed as epilepsy.Conclusions. Treatment of patients with gastrointestinal tumors is complex process and most commonly require close cooperation of various proffesional clinicians. Since asymptomatic course of disease and late stage of tumor advancement at diagnosis, technically difficult operations are often essential. Thus, surgeon who perform operations of patients with neuroendocrine tumors should be well experienced in carring out extensive surgical procedures.
