    Opis:
    Primary adenocarcinoma of the vermiform appendix is a rare clinical condition. It usually presents as an acute abdominal process or as a mass in the right lower quadrant. The gross pathologic and microscopic characteristics of this disease are the same as for colon carcinoma and carry a serious prognosis. We report a case of a 64-year old male patient presenting symptoms of acute appendicitis. The patient underwent laparoscopic appendectomy that revealed a severely inflamed appendix. Histopathological examination has shown that it was a poorly differentiated, high grade adenocarcinoma invading the periappendicular fat. According to the histopathological findings, a right hemicolectomy was further advised and performed. Right hemicolectomy is the generally recommended method of treatment for invasive adenocarcinoma of the appendix

    Opis:
    INTRODUCTION: Colonoscopy is considered to be a gold standard for colorectal cancer (CRC) screening. Endoscopy training is an essential component of general surgery training program. Patients should receive care at the highest level possible, nevertheless residents need to gain experience. The aim of our study was to evaluate the effectiveness of colonoscopy performed by general surgery residents by comparing quality indicators between surgical trainees and consultants. MATERIALS AND METHODS: The analysis included 6384 patients aged 40–65 who underwent screening colonoscopy between October 2014 and February 2018. The patients were divided into two groups: group I – patients examined by residents, group II - patients examined by board-certified general surgeons. Quality indicators such as cecal intubation rate, adenoma detection rate and patient tolerance scale were compared between the two groups. RESULTS: Group I comprised 2268 (35.53%) and group II 4116 (64.47%) patients. The overall cecal intubation rate (CIR) was 95.99%, equal for both groups (p = 0.994). There was no statistically significant difference in adenoma detection rate: 29.30% among residents and 27.66% among consultants (p = 0.203). Patient tolerance of the examination was very good (4-point scale) in consultants group in 78.98% of cases and in 75.18% cases among residents (p < 0.001). CONCLUSION: In a proper learning environment general surgery residents are able to perform high-quality and effective screening colonoscopy. However, residents need to continue the progress in their technique to improve patient tolerance in order to reach the proficiency of a consultant.

    Opis:
    Gall-stone disease constitutes a serious clinical problem and is the most frequent cause of elective cholecystectomies. There are many etiopatogenic factors however; lithogenic bile and its stasis due to gall-bladder hypomotility seem to be the most important. In recent years discovery of pacemaker function of Interstitial Cells of Cajal changed our understanding of smooth muscle physiology and helped to disclose many gastrointestinal motility disorders. The aim of the study was identification and quantification of interstitial Cajal-like cells (ICLCs) in gall-bladder muscle wall from patients with cholelithiasis and in gall-stone-free controls, as well as determination of the relationship between the number of ICLCs and Cholesterol Saturation Index (CSI) of bile in both analyzed groups. Material and methods. 20 patients operated for symptomatic cholelithiasis were enrolled into the study group. The control group consisted of 20 patients operated for pancreatic head tumors, with no pre- and intraoperative signs of gall-stones. Identification of ICLCs in the gall-bladder was performed by means of double immunofluorescence technique with anti c-Kit and anti-mast cell tryptase antibodies. Quantitative analysis was carried out under fluorescence microscopy conjoined with image analysis software. Bile samples were used for calculation of CSI. Results. ICLCs were detected within gall-bladder muscle wall. Number of ICLCs was statistically significantly lower in patients from the study group as compared to control. The study also revealed statistically significantly higher CSI in the study group. Conclusions. The quantity of ICLCs is diminished in the gall-bladder from patients with cholelithiasis and there is negative correlation between the number of ICLCs and CSI of bile. Regarding the role of ICCs in regulation of GI tract motility, it appears that reduction in their number may be important etiopatogenic factor of cholelithiasis.
