Pneumatosis cystoides intestinalis as a rare cause of non-surgical pneumoperitoneum.

Pneumoperitoneum as a finding on imaging examinations is not always a sign of acute abdomen due to gastrointestinal perforation. These findings must be viewed in connection with the clinical condition and personal history of each patient because they may also indicate a non-surgical or spontaneous pneumoperitoneum. This condition is repeatedly described but very often neglected. This paper presents the case report of a patient with non-surgical pneumoperitoneum where, despite proceeding according to the guidelines, no expected intra-abdominal pathology explaining the patient's problems was found.

Position of surgical treatment in step-up management of severe acute pancreatitis.

INTRODUCTION: The incidence of acute pancreatitis has been increasing over the past twenty years and there is still no causal treatment available. Although cases of severe acute pancreatitis account for only about a fifth of all cases of acute pancreatitis, high morbidity and lethality call for an optimization and unification of treatment procedures. METHODS: We operated on 27 patients suffering from severe acute pancreatitis in the past five years. We compared selected parameters such as gender, age, body mass index, aetiology, presence of type 2 diabetes, BISAP score, previous minimally invasive treatment and presence of the intraabdominal compartment syndrome. RESULTS: The average age of men and women was similar in our group. Most patients were overweight or obese. Alcoholic aetiology was more common in men while biliary aetiology prevailed in women. The mortality rate was 26% in our group. The intra-abdominal compartment syndrome followed by emergency decompression surgery was present in one fourth of the patients. A minimally invasive approach was used in approximately in one half of the patients, and surgical treatment was used only in cases where the minimally invasive approach failed. CONCLUSION: After each surgical revision, clinical deterioration of the patient´s condition occurs during the first two to three days in response to operative stress. Therefore, the current trend in the treatment of acute pancreatitis is to proceed as conservatively as possible, or using the minimally invasive approach, and surgical treatment should be reserved only for conditions that cannot be managed otherwise. If surgical treatment is used, it is advisable to perform cholecystectomy, whatever the aetiology of the pancreatitis.

Blood loss during HPB procedures.

INTRODUCTION: During the last decades, simultaneously with the development of surgical technique, modern equipment and perioperative management, there has been a significant improvement in postoperative outcome. Despite this, infectious complications and perioperative bleeding remain the leading causes of postoperative morbidity and mortality in HPB surgery. METHODS: We conducted a retrospective study over a three-year period in 256 patients who underwent surgery of the pancreas, liver, gallbladder, or bile ducts. We monitored perioperative blood loss, the number of administered transfusions, the type and severity of postoperative complications, the number of reoperations and the number of readmissions. RESULTS: The average blood loss was 457 ml. We administered transfusions to 39 patients (17%). We confirmed the hypothesis that the presence of blood loss statistically significantly increases the development of deep intra-abdominal infections (p=0.0188). Morbidity increases with increasing blood loss (p=0.0168). We confirmed a statistically significant difference in the blood loss between the groups with and without complications (p=0.001). Postoperative 30-day mortality was less than 1% (n=2). There were 15 (6%) reoperated patients, seven for acute bleeding and eight for infectious complications. The length of hospital stay was statistically significantly longer in patients who received transfusions - erythrocytes (p=0.023), and plasma (p=0.011). We readmitted 12 patients, three patients died during rehospitalization (the 90-day mortality rate was 2%, n=5). A total of 59% patients in our group were classified as ASA III. CONCLUSION: With increasing blood loss, morbidity (development of intra-abdominal infections) increases significantly, but despite this, overall post- operative mortality remains low. Early postoperative bleeding is the cause of more than half of reoperations. The length of hospitalization increases significantly with the number of transfusions administered.

Minimally-invasive pancreatic surgery in high volume centers in the Czech Republic - current status and possible implementations.

INTRODUCTION: Minimally-invasive surgical methods have been becoming ever more common also in the segment of pancreatic surgery. The aim of this paper was to analyze the current state of minimally-invasive surgery in the Czech Republic and the justification and potential of implementing such procedures. METHODS: Analysis of high volume centers using healthcare providers´ and payers´ data. RESULTS: Thirteen pancreatic surgical centers meet the proposed criteria for being called a high volume center - a center of highly specialized care in pancreatic surgery based on the annual number of at least 17 major resections of the pancreas. According to data from healthcare payers, laparoscopy was used in 0.6%-65.7% of procedures in individual centers. However, these are not resection procedures. The centers themselves report a significantly smaller number of minimally-invasive pancreatic resection procedures. The actual numbers of minimally-invasive resection procedures in the current system are practically impossible to verify. The potential for implementing minimally-invasive pancreatic surgery in the Czech Republic can be estimated based on the identification of candidate patients. CONCLUSION: Due to the fragmentation of this operative segment, its costs and small numbers of patients suitable for minimally-invasive pancreatic surgery even among high volume centers, the implementation rate of these methods is very slow. The need to centralize this segment of care appears to be very urgent from all points of view.

Historical overview of surgical procedures for chronic pancreatitis

Chronic pancreatitis accompanies the humankind for a long time. Its treatment has evolved from the "trial-error" method to the current pursuit of "evidence-based medicine". With the development of medical knowledge and progress in technology, the surgical operation gradually changed. Current practices are another step in the pyramid, the foundations of which were built by our courageous predecessors.

Tumor grade as significant prognostic factor in pancreatic cancer: validation of a novel TNMG staging system.

Aim of the study was to asses the tumor grade prognostic value in the Czech pancreatic cancer patients and to evaluate the accuracy of TNMG prognostic model. Retrospective analysis of 431 pancreatic cancer patients undergoing pancreatic resection in seven Czech oncological centers between 2003 and 2013 was performed. The impact of tumor grade and the accuracy of TNMG prognostic model were evaluated. Lymph node status, tumor size, tumor stage and grade were proved as statistically significant survival predictors. The lower tumor differentiation (grade 3 and 4) was associated with poorer prognosis in all stages (stage I: HR 2.23 [1.14; 4.36, CI 95%] p=0.019, stage II: HR 3.09 [2.01; 4.77, CI 95%] p=0.001, stage III and IV: HR 3.52 [1.73; 7.18, CI 95%] p=0.001). Kaplan-Meier analysis verified statistically significant impact of new TNMG stages on survival after resection for pancreatic cancer (p=0.001). In conclusion, we can state that the tumor grade was confirmed as statistically significant prognostic factor in pancreatic cancer. Its incorporation into the current TNM classification enables more accurate prognosis prediction within particular clinical stages. That is why an inclusion of the grade to the standard TNM classification should be discussed.

[Current status regarding surgical treatment of pancreatic cancer in the Czech Republic]. / Aktuální stav chirurgické lécby karcinomu pankreatu v Ceské republice.

INTRODUCTION: The aim is to map the current situation in the surgical treatment of pancreatic cancer in the Czech Republic. This information has been obtained from surgical treatment providers using a simple questionnaire and by identifying the so called high volume centres. The information has been collected in the interest of organizing and planning research projects in the field of pancreatic cancer treatment. METHOD: We addressed centres known to provide surgical treatment of pancreatic cancer. A simple questionnaire formulated one question about the total number of pancreatic resections, also separately for the diagnoses PDAC - C25, in the last two years (2014 and 2015). Other questions focused on the use of diagnostic methods, neoadjuvant therapy, preoperative assessment of risks, the possibility of rapid intraoperative histopathology examination, Leeds protocol, monitoring of morbidity and mortality including long-term results, and the method of postoperative follow-up and treatment. ÚZIS (Institute of Health Information and Statistics of the Czech Republic) was addressed with a request to analyze the frequency of reported total numbers for DPE, LPE, TPE and to do the same with respect to diagnosis C 25 for the last two years, available for the entire Czech Republic (2013, 2014). RESULTS: Altogether 19 institutions were identified by the preceding audit, which reported more than 10 pancreatic resections annually; these institutions were addressed with the questionnaire. Sixteen institutions responded to the questions, 13 of them completely. CONCLUSION: The majority of potentially radical surgeries for PDAC in the Czech Republic are carried out at 6 institutions. All of the institutions that participated in the survey collect data about morbidity and mortality and monitor their results. KEY WORDS: pancreas cancer outcomes surgery.

Solid pseudopapillary tumour of the pancreas: diagnosis, treatment, and prognosis.

BACKGROUND: Solid pseudopapillary tumour (SPT) of the pancreas is a relatively rare entity which most commonly occurs in young women. In this paper we report our clinical experience together with the current knowledge on the diagnostics, treatment and prognosis of this rare tumour. METHODS: We reviewed hospital records of patients diagnosed with a solid pseudopapillary tumour of the pancreas between January 2002 and December 2011 at the Department of Surgery, University Hospital Hradec Králové, Czech Republic. Clinical, operative, pathological data were obtained on all the patients. RESULTS: Over the 10-year period of the study we performed 181 planned pancreatic resections in our department. Overall, the 30-day postoperative mortality rate in this series of patients was 2.2%. SPT was diagnosed in 4 cases. All the patients were women and the average age was 34 years. Preoperative endosonography with biopsy sample was performed in all the patients and the diagnosis of SPT was known in all the patients before the surgical procedure. CONCLUSIONS: The current knowledge of SPT is based only on case reports and small series. It typically occurs in young women and therefore the presence of a large pancreatic mass in a young woman may suggest a diagnosis of SPT. SPT has a low malignant potential and the prognosis is excellent following complete surgical resection in the majority of the cases.

[The role of drains in pancreatic surgery]. / Význam drénu v pankreatické chirurgii.

Pancreatic fistula is a significant complication following pancreatic resection. Several methods aimed at lowering the postoperative pancreatic fistula rate were studied in the past. These methods mainly include pharmacological prophylaxis and technical modifications of pancreatic remnant management. Another method which can influence postoperative pancreatic fistula rate is the use of and the manipulation with intra-abdominal drains following pancreatic resection. Recent studies have shown that the use of the drains, the type of drain and manipulation with the drains can influence the outcomes. The aim of this review is to summarize current knowledge about the use of drains in pancreatic surgery. There are three questions to ask when studying the use of drains in pancreatic surgery: 1) Whether to use the drains at all 2) When to remove the drains? 3) Which type of the drain is more appropriate? Ad 1) Despite the growing number of studies showing comparable or even better results in patients without intra-abdominal drains following pancreatic resection, the latest randomized study proved that avoiding the use of drains is associated with more clinically significant postoperative complications and higher postoperative mortality. It is also important to consider the risk factors of pancreatic fistula development, especially pancreatic texture and the main pancreatic duct diameter. Currently, pancreatic resection without intra-abdominal drains cannot be routinely recommended. Ad 2) Two studies addressed the question when to remove the drains after pancreatic resection, and both studies clearly showed that early removal brings better results. Ad 3) No study has specifically addressed the question whether the type of drain can influence the rate of postoperative pancreatic fistula and of other complications. Gravity drains and closed-suction drains are most commonly used nowadays. The closed-suction drains are more effective due to the active suction. On the other hand, active suction can cause leak of the amylase-rich fluid through the pancreatic anastomosis or suture line and thus promote the development of pancreatic fistula or even worsen its clinical significance. There are no data in the literature so far regarding the type of drain. Therefore, we have commenced a randomized control trial which aims to compare closed-suction drains and closed gravity drains.

[Pancreatic fistula - definition, risk factors and treatment options]. / Pankreatická pístel - definice, rizikové faktory a moznosti lécby.

Pancreatic fistula is a common complication after pancreatic resections. Its incidence oscillates between 10 and 30%. The differences in the incidence cited in the studies are due to the various fistula definitions. According to ISGPF, pancreatic fistula is an output -via an operatively placed drain (or a subsequently placed percutaneous drain) - of any measurable volume of drain fluid on or after postoperative day 3, with an amylase content higher than 3 times the upper normal serum value. The fistula is then classified according to the clinical impact in grades A, B, and C. There are known three risk factor categories for the development of pancreatic fistula: the risk related to the pancreatic disease, to the patient, and to the surgical procedure. Most of the risk factors for the development of pancreatic fistula cannot be influenced either prior to or during the surgery. There are two basic options for the prevention of pancreatic fistula: pharmacological intervention (administration of somatostatin and its analogues) and technical modifications of the pancreatic remnant treatment. However, the routine administration of somatostatin and its analogues is not advisable in all pancreatic surgical procedures. In high risk cases the selective administration is preferred. The second option is modification of pancreatic remnant treatment. Most of the studies dealing with various modifications of the pancreatic remnant treatment were retrospective with lower level of evidence. There were only a few properly designed randomized trials, and most of them did not prove benefit of one method over another. It has been shown that the results depend on the experience of a given surgical department, and above all on the experience of an individual surgeon who performs the pancreatic resection. The therapy of pancreatic fistula is based on the clinical severity. Conservative approach is warranted in most patients. In cases when reoperation is required, there are two basic strategies: surgical drainage of the collections, and completion of total pancreatectomy. Total pancreatectomy was preferred in the past, however, this procedure is technically very demanding with mortality up to 80 per cent. Nowadays, most of the authors prefer surgical drainage; this procedure is technically less demanding, has lower mortality, the endocrine function of pancreas is protected, and the patients usually need no further interventions.

[Gun-shot injuries to the abdomen involving the pancreas]. / Strelná poranení dutiny brisní zasahující pankreas.

PURPOSE OF THE STUDY: The aim of the study is to present our experience with the diagnosis and therapy of penetrating abdominal injury involving the pancreas caused by a gun shot. MATERIAL AND METHODS: The group included patients with gun-shot abdominal injuries involving the pancreas who were treated at the Department of Surgery and the Department of Emergency Medicine at the University Hospital Hradec Králové. The extent of pancreatic injury was assessed using the American Association for the Surgery of Trauma (AAST) classification. The factors evaluated included the timing of surgery, operative strategy, operative time, blood loss, post-operative complications with pancreatic fistulas in particular, and the length of hospital stay. Pancreatic fistula was assessed according to the ISGPF (International Study Group for Pancreatic Fistula). RESULTS During the period of study lasting 10 years, three patients with gun-shot abdominal injuries involving the pancreas were treated. DISCUSSION: Pancreatic trauma due to a gun shot is a rare injury, but has also been reported in the Czech Republic. In any penetrating injury to the abdomen due to a gun shot, surgical exploration is always indicated and pancreatic trauma is usually found during the surgery. The first step in the procedure is to check all potential sources of bleeding because uncontrolled bleeding is the most frequent cause of intra-operative death. In a seriously injured patient, the technique of damage control surgery must be employed. After the major sources of bleeding have been checked, a thorough exploration of all abdominal organs should be performed to ascertain whether the main pancreatic duct has not been injured and, if so, in which part of the pancreas and to what extent. The correct classification of pancreatic injury according to the AAST is necessary to indicate appropriate therapy. Exploration for injury to other organs that often accompanies pancreatic trauma is a necessity. CONCLUSIONS: Penetrating pancreatic trauma is almost always associated with injury to the adjacent organs. All patients with gun-shot injuries to the abdomen are indicated for surgical exploration, thus the pancreatic injury is often found at the surgical exploration. After bleeding has been controlled, for treatment of the injured pancreas, simple drainage, or suture of the pancreatic capsule, or pancreatic resection or a patch with an excluded jejunal loop can be used. Partial duodenopancreatectomy is the last option because this procedure is associated with high morbidity and mortality.

[Palliative surgical treatment of tumors of pancreas and periampullary region]. / Paliativní chirurgická lécba nádoru pankreatu a periampulární oblasti.

BACKGROUNDS: Pancreatic cancer is an aggressive malignant disease with increasing incidence. Radical resection, the only potentially curative method, is possible in only 20-30% of patients. The main symptoms of advanced non-resectable pancreatic head tumors include obstructive jaundice, caused by stenosis of distal common bile duct, duodenal obstruction and pain, especially in the epigastric region and back. The aim of palliative treatment is to relieve these complaints. This paper evaluates our own palliative surgical treatment results in patients with pancreatic head and periampullary region cancer. PATIENTS AND METHODS: This study included all patients with pancreatic head and periampullary region cancer who underwent surgery at the Department of Surgery, University Hospital in Hradec Kralove from 1st January 2006 to 31st December 2010. The aim of the surgery in all patients was to resect the tumor. Palliative surgical procedure was performed in patients witn an inoperable tumor. We performed gastro-entero anastomosis in all the patients. When perioperative situation allowed, hepatico-jejuno anastomosis was performed in patients with obstructive jaundice. Surgical splanchnicectomy was performed in patients with back pain. RESULTS: Over five years, we performed a surgery in 94 patients for malignant disease of pancreas and periampullary region. Radical resection was performed in 45 patients. Palliative bypass procedure was performed in 42 patients. Exploration only was performed in 7 patients. Postoperative complications after palliative bypass procedures were noted in 15 patients (30.6%), the majority of these complications were minor. CONCLUSION: The advantage of surgical hepatico-jejuno anastomosis over endoscopically placed stent is particulary in superior long-term patency. Therefore, it is advisable to perform these procedures in patients with longer expected survival. Morbidity associated with palliative surgical procedures was relatively low and there was no mortality.

[Classification of surgical complications: analysis of the group of consecutive patients]. / Klasifikace chirurgických komplikací: analýza vlastní skupiny nemocných.

INTRODUCTION: The aim of the work was to evaluate the implementation of Clavien - Dindo classification of surgical complications into a routine clinical praxis and to evaluate the results achieved at the university department of surgery. MATERIAL AND METHODS: Prospectively collected data of patients hospitalized at the Clinic of Surgery of the University Hospital in Hradec Králové between January 2010 and September 2012 were retrospectively evaluated. Incidence, spectrum and severity of postoperative complications were evaluated according to individual surgical specializations. RESULTS: 9039 patients were operated and enrolled into the database during the time period from January 2010 to October 2012. A surgical complication was recorded in 1248 (12.9%) patiens, grade I. in 284 (3.4%) cases, grade II. in 384 (4.3%) cases, grade III in 370 (4.1%) cases, grade IV. in 67 (0.7%) patients. Death,i.e. grade V., occurred in 143 (1.43%) patients. CONCLUSION: Clavien - Dindo classification of surgical complications was successfully implemented into a routine clinical praxis at the department of surgery, University Hospital Hradec Králové. Wider use of this classification system would improve conditions for evaluation and comparison of results between different surgical approaches, surgeons or departments.

Can the prophylactic administration of tranexamic acid reduce the blood loss after robotic-assisted radical prostatectomy? Robotic Assisted Radical Prostatectomy with tranEXamic acid (RARPEX): study protocol for a randomized controlled trial.

BACKGROUND: The prophylactic administration of tranexamic acid reduces blood loss during procedures at high risk of perioperative bleeding. Several studies in cardiac surgery and orthopedics confirmed this finding. The aim of this prospective, double-blind, randomized study is to evaluate the effect of tranexamic acid on peri-and postoperative blood loss and on the incidence and severity of complications. METHODS/DESIGN: Based on the results of our pilot study, we decided to conduct this prospective, double-blind, randomized trial to confirm the preliminary data. The primary endpoint is to analyze the effect of tranexamic acid on perioperative and postoperative blood loss (decrease in hemoglobin levels) in robotic-assisted radical prostatectomy. The additional endpoint is to analyze the effect of tranexamic acid on postoperative complications and confirm the safety of tranexamic acid in robotic-assisted radical prostatectomy. DISCUSSION: No study to date has tested the prophylactic administration of tranexamic acid at the beginning of robotic-assisted radical prostatectomy. This study is designed to answer the question of whether the administration of tranexamic acid might lower the blood loss after the procedure or increase the rate and severity of complications. TRIAL REGISTRATION: ClinicalTrials.gov NCT04319614. Registered on 25 March 2020.

Radiofrequency-assisted liver resection: higher incidence of infectious complications?

AIM: To evaluate clinical experience with radiofrequency (RF)-assisted liver resection in non-cirrhotic and non-cholestatic patients with metastatic liver disease. METHODS: A group of consecutive patients who underwent RF-assisted liver resection for metastatic liver disease was prospectively followed. RESULTS: Between July 2005 and April 2008, 95 liver RF-assisted liver resections were performed, 71 of them for metastatic liver disease. The mean hospital stay was 14 (range 5-40) days. The mean operation time was 141 (range 64-233) minutes. The mean duration of RF coagulation was 10 (range 9-12) minutes. A total of 37 complications in 24 (33%) patients were recorded, including 12 (16.9%) infected collections in resection line that had to be drained percutaneously. The 30-day postoperative mortality was zero. CONCLUSION: This study indicates that RF-assisted resection may have a benefit in decreasing peroperative blood loss and the number of blood transfusions. Nevertheless, an increased incidence of infectious complications and pleural effusions that required evacuation was noted.

Giant biliary cystadenoma: a case report.

Biliary cystadenoma is a very rare benign cystic tumour of the liver. Fewer than 150 cases have been described in the literature so far. The authors present a case of a 29-year-old female with a giant intrahepatic biliary cystadenoma who presented with abdominal pain and obstructive jaundice. The patient was treated with left hepatectomy and now 12 months after the surgery she is in good condition with no signs of recurrence of the disease. Clinical presentation of biliary cystadenoma is not specific. Diagnosis is based on imaging methods, mainly ultrasound and CT scan. However, it is often misdiagnosed. For treatment, radical resection is advocated because a biliary cystadenoma is considered to be a premalignant lesion. The prognosis of biliary cystadenoma after complete resection is excellent. Nevertheless, there is a risk of recurrence or malignant transformation after incomplete resection.

[Current trends of surgical therapy of focal liver and pancreatic lesions]. / Soucasné moznosti chirurgické lécby loziskového postizení jater a pankreatu.

Focal liver and pancreatic lesions represent important therapeutic problem in a relatively huge group of patients. Secondary liver tumors are the crucial factor affecting morbidity and mortality in patients with malignancies. Radical surgery is the only therapeutic option that gives the chance of long-term survival. The authors present current trends in surgical therapy of liver and pancreatic tumors as a review article.

[Laparoscopic pancreatic resections in experimental setting and clinical practice]. / Laparoskopická resekce pankreatu v experimentu a klinické praxi.

INTRODUCTION: Pancreatic fistula is a major postoperative complication after pancreatic resection. One of the main risk factors of developing the pancreatic fistula after distal pancreatectomy is the method employed for the management of the pancreatic remnant. AIM OF THE STUDY: The aim of the experimental part of this work was to test a novel method of management of the pancreatic remnant after distal pancreatectomy on a large laboratory animal. Furthermore, based on the experience with the experimental work to introduce the laparoscopic approach to human clinical practice. METHODS: In the experimental part of the work laparoscopic distal pancreatectomy with spleen and splenic vessels preservation was performed in ten female domestic pigs. The experimental animals were divided into two groups. In the first group the pancreas was transected using an EndoGIA Universal Stapler and in the second group, the pancreas was transected using a Ligasure device and the pancreatic remnant was reinforced with hydrogel sealant Pleuraseal. We introduced the laparoscopic distal pancreatectomy to clinical practice in the Department of Surgery in Hradec Králové in 2009. Transection of the pancreas was performed with staplers. RESULTS: In the experimental part of the work the postoperative course was uneventful in all the animals. All animals gained weight. Only minor macroscopic and microscopic alterations of the healing process were found. Statistical differences between the groups were not significant. In the clinical part of the work we performed laparoscopic distal pancreatectomy in 6 patients. We performed two distal pancreatectomies with splenectomy, one distal pancreatectomy with splenectomy and left nephrectomy and 3 distal pancreatectomies with the spleen and splenic vessels preservation. We did not have to convert to open procedure in any of the cases. CONCLUSIONS: In the experimental part of the work we showed that the novel technique using Ligasure transection reinforced by the hydrogel sealant Pleuraseal is feasible and safe technique, which seems to be comparable with the standard transection technique using stapler. Our initial experience with laparoscopic distal pancreatectomy in the clinical practice cannot be used to compare various methods of management of the pancreatic stump or to evaluate the rate of pancreatic fistula in such small group of patients.

[Numbers of lymph nodes in large intestinal resections for colorectal carcinoma]. / Pocet uzlin u resekcí tlustého streva pro kolorektální karcinom.

INTRODUCTION: Precise evaluation of lymph nodes in the surgical specimen is crucial for the staging and subsequent decision about the adjuvant therapy in colorectal cancer. Prognosis of the patients can be assessed only in cases when at least 12 lymph nodes in the surgical specimen are examined. AIM OF THE WORK: To evaluate the radicalism of resections for colorectal carcinoma after introducing laparoscopic approach. METHODS: We compared all resections for primary colorectal cancer and rectal cancer (C 18-C20) performed in the Department of Surgery in University Hospital Hradec Králové in the years 2005 and 2008 and we evaluated numbers of examined lymph nodes in the surgical specimens. The patients with recurrent tumours and the patients with complete pathological response (negative histology) after neoadjuvant therapy were excluded from the study. RESULTS: 117 patients were included in the study in 2005, 2 of them were operated laparoscopically. 155 patients (more by 32.5%) were included in the study in 2008, 53 of them (34.2%) were operated laparoscopically. In tumours of the right part of the colon (C180-C184) treated by right hemicolectomy: on an average 7.9 (+/- 5.3) lymph nodes were examined in the specimens in 2005, and 15.3 (+/- 7.0) lymph nodes in 2008. In tumours of the left part of the colon (C185-C186) treated by left hemicolectomy: 6.5 (+/- 5.1) lymph nodes were examined in 2005, and 19.6 (+/- 15.6) in 2008. In tumours of the sigmoid colon (C187) 9.1 (+/- 6.9) lymph nodes were examined in 2005,and 15.4 (+/- 7.9) in 2008. In tumours of the rectosigmoid junction (C19) 8.0 (+/- 6.9) lymph nodes were examined in 2005, and 17.8 (+/- 11.2) in 2008. In rectal cancer (C20) 5.2 (+/- 4.5) lymph nodes were examined in 2005, and 13.6 (+/- 12.5) in 2008. There is a significant difference in a number of examined lymph nodes in patients without neodadjuvant treatment compared to those with neoadjuvant chemoradiotherapy and neoadjuvant radiotherapy. In 2005, in an average 3.7 (+/- 3.3) lymph nodes were removed in rectal resections after neoadjuvant chemoradiotherapy, in 2008 in an average 7.6 (+/- 6.1) lymph nodes were removed. In 2005, in an average 5.1 (+/- 3.7) lymph nodes in rectal resections after neoadjuvant radiotherapy were removed, in 2008 6.3 (+/- 4.3) lymph nodes were removed. In 2005, in an average 7.0 (+/- 5.5) lymph nodes in rectal resections without neoadjuvant therapy were removed, in 2008 20.9 (+/- 14.1) lymph nodes were removed. Laparoscopic resections were comparable with open resections regarding the number of examined lymph nodes in our group of patients. CONCLUSION: Introducing the laparoscopic approach to resections of colorectal carcinomas did not decrease radicalism of the operation as to the number of removed lymph nodes.

[Laparoscopic liver resections. Successes and failures associated with the technique introduction--case reports]. / Laparoskopické resekce jater. Uspechy a nezdary spojené se zavedením techniky--soubor kazuistik.

The authors present initial clinical experience with laparoscopic liver resections as a case report series. The operation time, hospital and ICU stay length, perioperative blood loss, transfusion units used, and postoperative complications were recorded in a prospective way. The reasons for conversion to open surgery were also evaluated. 15 laparoscopic liver resections were completed between May 2006 and February 2009. There were 11 anatomical resections including hemihepatectomies and 4 non-anatomical laparoscopicaly completed liver resections. The initial experience shows that laparoscopic liver resection is feasible and safesate approach that requires advances experience in laparoscopic operative technique and liver surgery. Introduction of the laparoscopic technique is not easy and is associated with high risk of hilar bile duct injuries and perioperative bleeding.
