With sufficient experience, laparoscopic colorectal surgery in obese patients is feasible and safe. It is associated with no increased risk of complications and preserves all benefits of the mini-invasive approach.
Primary endovascular therapy for acute embolic SMA occlusion with on-demand laparotomy is a recommended algorithm used in our centre to treat SMA occlusion. This combined approach for the treatment of AMI is associated with in-hospital mortality rate of 27.0 %.
IntroductionLong-term results after laparoscopic surgery with conversion to open surgery for colorectal cancer are seldom published.AimThe study analysed the impact of conversion of laparoscopic surgery to open resection for colorectal cancer on short- and long-term results.Material and methodsThe prospectively collected data of 469 patients with colorectal cancer in the period from 1 January 2001 to 31 December 2006 were analysed. Short- and long-term results were compared.ResultsThe relative frequency of conversion was 7%. The subgroups were statistically similar regarding age, gender, body mass index (BMI), localization of tumour, T stage, and TNM stage. We observed a lower frequency of previous surgery (p = 0.018) in the group of patients with conversions to open surgery as well as statistically significantly higher frequency of patients with American Society of Anesthesiologists (ASA) score II (p = 0.039). There was no statistical difference in morbidity, mortality, or the length of hospital stay between both the groups of patients. The operating time was significantly higher in the group of patients with conversion (p = 0.00001). There was a significantly higher blood loss in the patient groups with conversion to open surgery and in the group with primarily open surgery (p = 0.00023). There was no difference in the overall survival (p = 0.712), disease-free survival (p = 0.072) or in the local (p = 0.432) or distant (p = 0.957) recurrence.ConclusionsNo negative impact on short- or long-term results of conversion to open surgery was verified in patients with colorectal surgery.

Abstract Retrorectal cysts are rare benign lesions in the presacral space which are frequently diagnosed in middle-aged females. We report here our experience with two symptomatic female patients who were diagnosed as having a retrorectal cyst and managed using a laparoscopic approach. The two patients were misdiagnosed as having an ovarian cystic lesion after abdominal ultrasonography. Computer tomography (CT) scan was mandatory to establish the diagnosis. The trocar port site was the same in both patients. An additional left oophorectomy was done for a coexisting ovarian cystic lesion in one patient in the same setting. There was no postoperative morbidity or mortality and the two patients were discharged on the 5th and 6th post operative days, respectively. Our cases show that laparoscopic management of retrorectal cysts is a safe approach. It reduces surgical trauma and offers an excellent tool for perfect visualization of the deep structures in the presacral space.
Patients presenting with minor to severe ischemic stroke syndromes due to isolated extracranial ICA occlusion may benefit from emergent carotid revascularization. Thorough preoperative neuroimaging is essential to aid in selecting eligible candidates for acute surgical intervention.
The aim of our study was to evaluate the prognostic significance of blood transfusion on recurrence and survival in patients undergoing curative resections for colorectal cancer. Retrospective analysis of prospectively collected data of patients after elective resections for colorectal cancer between January 2001 and December 2009 was undertaken. The main endpoint was overall survival, disease-free survival, and recurrence rate. These data were evaluated in relation to blood transfusion (group A, no blood transfusion; group B, one to two blood transfusions; group C, three and more blood transfusions). A total of 583 patients met the criteria for inclusion in the study. Of these, 132 (22.6 %) patients received blood transfusion in the perioperative period. There were 83 (14.2 %) patients who received one or two blood transfusions and 49 (8.4 %) patients who required three or more transfusions. Patients with three or more transfusions had a significantly worse 5-year overall survival, disease-free survival, and increased incidence of distant recurrences in comparison with the group without transfusion or the group with one or two transfusions. Multivariate analysis showed that the application of three or more blood transfusions is an independent risk factor for overall survival (P 00.001; HR 2.158; 95 % CI 1.370-3.398), disease-free survival (P<0.001; HR 2.514; 95 % CI 1.648-3.836), and the incidence of distant recurrence (P<0.001; HR 2.902; 95 % CI 1.616-5.212). Application of three or more blood transfusions in patients operated for colorectal carcinoma is an adverse prognostic factor. Indications for blood transfusion should be carefully considered not only with regard to the risk of early complications, but also because of the possibility of compromising long-term results.
Background. Vascular allotransplantations are performed worldwide in selected patients suffering from vascular prosthesis infection or critical limb ischemia. Either fresh or cryopreserved vascular allograft may be used. Objectives. In various points, we address several aspects (allograft procurement, cryopreservation and transplantation technique) of the program of vascular allotransplantations in the Czech Republic. Materials and methods. Vascular grafts retrieval has been done within multiorgan harvests using no-touch technique. Very short time of cold ischemia is achieved due to close cooperation with Tissue Establishment where the following processing of cryopreservation is performed. Meeting all necessary quality criteria is a prerequisity for releasing grafts for clinical application. Standardized thawing protocol and surgical handling aims to minimize microfractures before implantation. Results. Based on experimental and clinical work, the first validation of cryopreserved arterial and venous grafts for clinical use was performed between 2011 and 2013 in the Czech Republic. The developement of storage of vascular tissue in banks was stimulated in 2000-2010 by the issue of EU directives and national harmonized norms, aimed at assurance of high quality and safety of cells and tissues used for transplantations in humans. Conclusions. There are several crucial moments affecting final quality, including graft retrieval within a multiorgan harvest, short ischemic time, cryopreservation, and thawing technique used. The recommended surgical handling during implantation may also affect results and graft-related complications.
Although natural orifice specimen extraction is now relatively widely performed, there have been no reports on gastric resection with specimen extraction through the transgastric route for peptic ulcer disease. A hybrid technique of the laparoscopic and endoscopic approach is presented in the case of a 58-year old male patient. Preoperative gastric fibroscopy showed postulcer pyloric and antral stenosis. Laparoscopic exploration confirmed gastric enlargement. Laparoscopic two-thirds gastrectomy was performed. The staple line suture of the residual stomach was excised and the specimen was extracted through the esophagus and mouth with a gastroscope. Finally, the residual stomach was closed again using linear endostaplers. Reconstruction was performed according to the Roux-en-Y method. Gastric resection using natural orifice specimen extraction (NOSE) may be a feasible operative procedure. The NOSE with the combination of standard laparoscopy and specimen extraction through a natural orifice can be considered as a bridge to natural orifice translumenal endoscopic surgery.
