Opis:
Wide propagation of new generation of electrosurgical devices such as bipolar vessel sealing systems (eg. Thermostapler® by EMED) enabled seamless closing of blood vessels with a diameter up to 7 mm while maintaining the necessary safety margin, as well as reducing the duration of the operation. We decided to verify these reports in our material. Aim of the study was comparison of thyroid surgery performed with the electrocautery tool – Thermostapler® by EMED with surgery using classic hemostasis technique to evaluate the operative time and complications in the form of bleeding, recurrent laryngeal nerve paralysis, symptoms of hypoparathyroidism, and wound infection. Material and methods. We retrospectively analyzed 256 patients operated in the Department of General and Proctological Surgery Solec Hospital in Warsaw due to inert thyroid goitre. All patients underwent total thyroidectomy. Patients were divided into two groups. The first group consisted of 126 patients operated in 2000, using classic techniques of hemostasis. While the second group consisted of 130 patients operated in 2007-2008 with Thermostapler®. We compared duration of surgery and the incidence of postoperative complications. Results. The operative time was significantly shorter (average 18 minutes) in the second group of patients. We also recorded a statistically significant decrease in the incidence of complications in the group operated with Thermostapler. conclusions. Use of bipolar vessel sealing system in a decisive manner shortens the duration of operation. Use of bipolar vessel sealing system also enables a radical reduction in the incidence of complications rate such as bleeding, recurrent laryngeal nerve paralysis, symptoms of hypoparathyroidism, and wound infection. In the future, similar studies should be performed to assess the real costs resulting from the use Thermostapler®

Opis:
The “Polish Research on Gastric Cancer” project has been continued since 1986. The main aim of this project, which is a multicenter and interdisciplinary research, is enhancing the treatment results of gastric cancer patients by developing and promoting the use of optimal methods for diagnosis and treatment, both surgical as well as combined. One of the more important achievements of the project is the development and publication of a document named “Polish Consensus on Treatment of Patients with Gastric Cancer”, whose first version was published in 1998. Following versions were updated adequately to changing trends in the proceedings in patients with gastric cancer. A scientific symposium on “Polish Consensus on Treatment of Gastric Cancer – update 2016” was held in 3-4 June 2016 in Cracow. During the symposium a panel session was held during which all authors publicly presented the Consensus assumptions to be discussed further. Moreover, the already mentioned session was preceded by a correspondence as well as a working meeting in order to consolidate the position. It has to be underlined that the directions and guidelines included in the Consensus are not the arbitrarily assumed rules of conduct in a legal aspect and as such every doctor/team of doctors is entitled to make different decisions as long as they are beneficial to a patient with gastric cancer. The Consensus discusses as follows: a) recommended qualifications (stage of advancement, pathological, lymph node topography and the extent of lymphadenectomy, division of cancer of the gastroesophageal junction), b) rules for diagnostics including recommendations regarding endoscopic examination and clinical evaluation of the advancement stage, c) recommendations regarding surgical treatment (extent of resection, extent of lymphadenectomy, tactics of proceedings in cancer of the gastroesophageal junction), d) recommendations regarding combined treatment with chemotherapy or radiotherapy, e) place of endoscopic and less invasive surgery in the treatment of gastric cancer. This publication is a summary of the arrangements made in the panel session during the abovementioned scientific symposium in Cracow in 2016.

Opis:
The aim of the study was to analyze indications and results of the first one thousand liver transplantations at Chair and Clinic of General, Transplantation and Liver Surgery, Medical University of Warsaw.Material and methods. Data from 1000 transplantations (944 patients) performed at Chair and Clinic of General, Transplantation and Liver Surgery between 1994 and 2011 were analyzed retrospectively. These included 943 first transplantations and 55 retransplantations and 2 re-retransplantations. Frequency of particular indications for first transplantation and retransplantations was established. Perioperative mortality was defined as death within 30 days after the transplantation. Kaplan-Meier survival analysis was used to estimate 5-year patient and graft survival.Results. The most common indications for first transplantation included: liver failure caused by hepatitis C infection (27.8%) and hepatitis B infection (18%) and alcoholic liver disease (17.7%). Early (< 6 months) and late (> 6 months) retransplantations were dominated by hepatic artery thrombosis (54.3%) and recurrence of the underlying disease (45%). Perioperative mortality rate was 8.9% for first transplantations and 34.5% for retransplantations. Five-year patient and graft survival rate was 74.3% and 71%, respectively, after first transplantations and 54.7% and 52.9%, respectively, after retransplantations.Conclusions. Development of liver transplantation program provided more than 1000 transplantations and excellent long-term results. Liver failure caused by hepatitis C and B infections remains the most common cause of liver transplantation and structure of other indications is consistent with European data.

Opis:
The Suchedniów water reservoir is located in the central section of the River Kamionka in the northern part of the Holy Cross Mountains of central Poland. This area once belonged to the Old Polish Industrial District that, during the Middle Ages, was very intensively developed by iron metallurgy. Many forges and mills along the rivers used water power, which led to the construction of an anthropogenic, small-scale water retention system. At the beginning of the twentieth century many of these reservoirs were drained after the collapse of metallurgical activities. The present-day reservoir was built in 1974 and drained in 2017. Research into the drained basin has documented various forms and sediments, some of which record present-day depositional processes (fire proof clay layer, inland fan delta), while others represent the historical period (lacustrine sediments of older reservoirs). Traces of catastrophic events have been preserved as well; an assemblage of megaripples marks the sudden drainage caused by a dam break in 1974.
