About half of million deaths caused by colorectal cancer (CRC) has been reported worldwide every year. Programmes for early diagnosis of CRC has reduced mortality due to this disease, as the cancer is diagnosed in earlier stages which can be treated more successfully. Programme for early CRC diagnosis in Lithuania has been based on the faeces occult blood test (FOBT). If positive FOBT result is obtained, patients should be referred for colonoscopy (CS) examination. Based on the data from the National Health Fund, during the first three years CS examination was carried out for a little bit more than half of the patients participating in the programme and presenting with positive FOBT result. Aiming to improve accuracy of CRC diagnostics we have suggested alternative CS examination – computed tomography colonography (CTC). The aim of our study was to establish diagnostic value of CTC examination in the identification of neoplastic alterations in the patients with positive FOBT result and to specify factors having influence on the examination quality. CTC examinations were carried out and their results were compared with the findings of CS. We discovered that CTC is of high diagnostic value for detection of lesions sized ≥ 6 mm and of very high diagnostic value for detection of large ( ≥ 10 mm) polyps in a colon. We found out that the length of colon had no influence on how patients tolerated this examination and on patients well-being during CTC procedure, and colon cleaning...

SŽV ankstyvosios diagnostikos programos sumažina mirtingumą nuo šios ligos, nes vėžys tada yra aptinkamas anksčiau ir galima jį lengviau išgydyti. Lietuvoje SŽV ankstyvosios diagnostikos programa yra paremta slapto kraujo išmatose nustatymo testu (FOBT). Po teigiamo FOBT atsakymo pacientai yra nukreipiami kolonoskopijai (KS). Valstybinės ligonių kasos duomenimis per pirmuosius trejus metus iš pacientų, dalyvavusių programoje, kuriems nustatytas teigiamas FOBT, iš jų tik kiek daugiau nei pusei pacientų atlikta KS. Norint dažniau diagnozuoti SŽV, pasiūlėme alternatyvų KS tyrimą - kompiuterinės tomografijos kolonografiją (KTK). Taikydami KTK ir lygindami jos rezultatus su KS, norėjome išsiaiškinti KTK tyrimo diagnostinę vertę nustatant neoplastinius pakitimus pacientams su teigiamu FOBT bei nustatyti tyrimo kokybei darančius įtaką faktorius. Nustatėme, kad KTK pasižymi didele diagnostine verte nustatant ≥6 mm dydžio pakitimus bei labai didele diagnostine verte nustatant didelius (≥10 mm) polipus, storojoje žarnoje. Nustatėme, kad storosios žarnos ilgis neturi įtakos KTK tyrimo tolerancijai ir paciento savijautai KTK metu, o žarnos išsivalymo kokybė prieš KTK tyrimą nepriklauso nuo anatominių storosios žarnos savybių – tokių, kaip ilgis. Išsiaiškinome, kad KTK tyrimas yra jautrus nustatant storosios žarnos neoplastines adenomas ir vėžį, bet nesiekia KS tyrimo jautrumo, todėl KTK taikyti... [toliau žr. visą tekstą]

<p>UVOD: Kolorektalni karcinom je na trećem mestu po učestalosti oboljevanja od svih karcinoma uz porast incidencije CRC u visoko razvijenim zemljama.70% obolelih od CRC je starije od 65 godina uz veću incidenciju proksimalnih karcinoma u odnosu na distalne u svim uzrasnim grupama i kod oba pola. Smatra se da bi 66-75% slučajeva CRC moglo biti izbegnuto zdravim načinom života. 75% CRC nastaje iz adenomatoznih preko polip kancer sekvence i da vi&scaron;e od 90% adenoma neće progredirati u karcinom. U studijama skrining kolonoskopija prijavljeno je 6-12% neviđenih velikih polipa i ko 5% CRC na inicijalnom kolonoskopskom pregledu. Postoperativne periodične kolonoskopije nakon operacije kolorektalonog karicinoma imaju za cilj otkrivanje metahronih carcinoma polipa kao pojavu bolesti na anastomozi ali nije dokazani benefit u preživljavanju bolesnika koji su imali učestalije postoperativne kolonoskopije (na godinu dana) u odnosu na one koji su praćenina 3 ili 5 godina. CILJEVI ISTRAŽIVANJA: Prospektivno ispitivanje pojave intervalnih lezija kolona (malignih i premalignih) u periodu od 2-7 godine od prve negativne kolonoskopije bez obzira na razlog pregleda. Ispitivanje razlike u životnim navikama između ispitanika u zavisnosti od nalaza na ponovljenoj kolonoskopiji. Retrospektivna analiza svih dijagnostičkih i kontrolnih kolonoskopija. MATERIJAL I METODE: Ponavljana je kolonoskopija kod ispitanika koj su na dijagnostičkim kolonoskopijama rađenim na Institutu za onkologiju Vojvodine u periodu 2005-2011. imali uredan kolonoskopski nalaz. Od 160 pozvanih ispitanika na ponovnu kolonoskopiju se odazvalo 64 ispitanika a 151 ispitanik je popunio upitnik o životnim navikama. Urađena je i retospektivna analiza 2750 dijagnostičkih kolonoskopija. Analizirani su rezultati 1064 prvih postoperativnih kolonoskopija kao i nalazi sa 1147 ponovljenih kolonoskopija kod ispitanika operisanih od kolorektalnog carcinoma koji su imali uredan nalaz na prvoj kolonoskopiji. REZULTATI: Od 160 pozvanih ispitanika,njih 64 (42,3%) se odazvalo na ponovni pregled (45 žena i 19 mu&scaron;karaca) prosečne starosti60,13 godina. Kod 15 ispitanika(24.3%) nađeno je ukupno 22 polipa (10 žena i 5 mu&scaron;karaca) bez statistički značajne razlike u pozitivnosti nalaza u odnosu na pol (x2test; x2=0,014; p=0,904) i pozitivnu porodičnu anamnezu (x2test; x2=0,125; p=0,724). 12 slucajeva (14,06%) su bili polipi visokog rizika: 5 (41.6%) lokalizovano u proksimalnom kolonu i 7 (58.3% ) u distalnom kolonu. Nije dijagnostikovan nijedan intervalni karcinom. Nije dokazana statistički značajna razlika u pozitivnosti nalaza na ponovljenoj kolonoskopiji u odnosu na razmak posmatran u grupama do 3 i do 5 godina od predhodne kolonoskpije (x2test; x2=0,020; p=0,887) niti ukoliko se posmatra po grupama do 5 i preko 5 godina od negative kolonoskopije (x2test; x2=3,082; p=0,079). Nema statistički značajne razlike u pozitivnosti nalaza na ponovljenoj kolonoskopiji u odnosu na to da li su pacijenti konzumiraju alkohol ili ne (x2test; x2=0,113; p=0,911) kao i u odnosu na to da li su pacijenti imali redovnu fizičku aktivnost (x2test; x2=0,476; p=0,490). Na dijagnostičkim kolonoskopijama je uočena statistički značajna razlika u uzrastu pacijenata u zavisnosti od razloga kolonoskopije (F=7,111; p=0,000) kod pacijenata kod kojih su dijagnostikovani polipi. Oni sa pozitivnom porodičnom anamnezom i polipima su statistički značajno mlađi u odnosu na ostale osim onih koji su se na pregled javili zbog bola u trbuhu poremećaja ritma stolice. Nije bilo statistički značajne razlike po polu, uzrastu, u razlogu kolonoskopije kod osoba sa dijagnostikovanim polipima. Statistički je značajniji broj žena sa lokalizacijom polipa u distalnom delu debelog creva u odnosu na proksimalni (x2test; x2=18,495; p=0,000). Kod mlađih uzrasnih grupa statistički značajnije su zastupljeni polipi u rektumu(x2test; x2=79,963; p=0,000). Ispitanici sa proksimalnom lokalizacijom polipa imaju 1,724 puta veću &scaron;ansu za adenome visokog rizika u odnosu na one sa distalnom lokalizacijom. Nema statistički značajne razlike u distribuciji karcinoma u odnosuna pol (x2test; x2=3,2110; p=0,201). Na 1064 prvih postoperativnih kolonoskopija je bilo ukupno 346 (32,5%) pozitivnih nalaza. Dijagnostikovano je 60 karcinoma od kojih je 43,3 % lokalizovano na anastomozi a kod 286 ispitanika nađeno je ukupno 546 polipa. Mu&scaron;karci statistički značajnije če&scaron;će imaju pozitiva nalaz (x2 test; x2=17,252; p=0,000). Bonferroni post hoc testom je utvrđeno da su polipi proksimalne lokalizacije statistički značajno veći od onih u rektumu (p=0,043). Na kontrolnim kolonoskopijama rađenim u cilju praćenja nakon resekcije kolorektalnog karcinoma multivarijatnom analizom ( pol, uzrast i vreme od operacije) utvrđeno je da mu&scaron;karci imaju 1,4 puta veću &scaron;ansu (OR=1,457) od žena za pojavu promena (polipa i karcinoma).Ispitanici kod kojih je od operacije pro&scaron;lo od 3 do 5 godina imaju 1,6 puta veću &scaron;ansu za pojavu promene u odnosu na one kod kojih je pro&scaron;la 1 godina (OR=1,605). ZAKLJUČAK: Kod 24.3% pregledanih ispitanika dijagnostikovani su polipi(jedan hipeplastičnii 21 adenoma ). 14,06% svih polipa je imalo karakteristike polipa visokog rizika bez statistički značajne razlike u pojavi polipa kod ispitanika kod kojih je pregled rađen 3,5 ili nakon 5 godina od prve negativne kolonoskopije. Nije dijagnostikovan niti jedan karcinom &scaron;to znači da nema potrebe za ponavljanjem kolonoskopija u kraćem vremenskom intervalu od unapred planirane kolonoskopije kod ispitanika koji su imali uredan inicijalni kolonoskopski nalaz &scaron;to se odnosi i na ponavljane kolonoskopije kod ispitanika operisanih od CRC-a. Na dijagnostičkim kolonoskopijama statistički značajniji broj žena sa lokalizacijom polipa u distalnom delu debelog creva u odnosu na proksimalni i nije zapažena razlika u distribuciji karcinoma u odnosu na pol i uzrast ispitanika.</p> / <p>INTRODUCTION:Colorectal cancer is the third most frequent illness of all carcinomas with an increase in the incidence of CRC in highly developed countries. 70% of patients with CRC are older than 65 years with higher incidence of proximal cancers compared to distal in all age groups and in both sexes. It is believed that 66-75% of CRC could be avoided through healthy lifestyle. 75% of CRC arise from adenomatous polyp cancer via sequences, and that more than 90% of adenoma will not progress to carcinoma. In studies of screening colonoscopy was reported 6-12% of unobserved large polyps and approximately 5% of the CRC on the initial colonoscopy.Postoperative periodic colonoscopy after colorectal cancer surgery aim to detect metachronous cancer and polyps and disease occurrence anastomoses but not proven survival benefit in subjects who had more frequent postoperative colonoscopy (per year) compared to those who were followed for 3 or 5 years. AIM:Prospective study of interval colon lesions occurrence (malignant and pre-malignant) in the period from 2-7 years after initial negative colonoscopy regardless of the reason for the check. Test of differences in lifestyle between subjects depending on the findings of the repeated colonoscopy.A retrospective analysis of all the diagnostic and control colonoscopy. METHODOLOGY: Repeated colonoscopy in subjects who are at-made diagnostic colonoscopy at the Oncology Institute of Vojvodina in the period 2005-2011 had normal colonoscopy findings. Of the 160 subjects invited to re colonoscopy for review responded 64 subjects and 151 subjects filled out a questionnaire about life habits. Retrospective analysis of 2750 and diagnostic colonoscopy has been done. Results of the 1064 first postoperative colonoscopy and results of the 1147 repeated colonoscopy in patients operated on for colorectal cancer that had normal findings on the first colonoscopy has been analyzed. RESULTS:Of the 160 invited subjects, 64 of them (42.3%) responded to the repeated review (45 women and 19 men), mean age 60.13 years. In 15 subjects (24.3%) found a total of 22 polyps (10 women and 5 men) with no statistically significant differences in positivity findings in relation to sex (x2test; x2 = 0.014; p = 0.904) and a positive family anamnesis (x2test; x2 = 0.125; p = 0.724).12 cases (14.06%) were high risk of polyps: 5 (41.6%) localized in the proximal colon, and 7 (58.3%) in the distal colon. Not a single interval cancer diagnosed. There was no statistically significant difference in positivity findings with repeated colonoscopy in relation to the distance observed in groups of 3 to 5 years from the previous colonoscopy (x2test; x2 = 0.020; p = 0.887) or when observed in groups up to 5 and over 5 years of negative colonoscopy (x2test; x2 = 3.082; p = 0.079). No statistically significant differences in positivity findings with repeated colonoscopy in relation to whether the patients consume alcohol or not (x2test; x2 = 0.113; p = 0.911) as well as in relation to whether patients are regularly exercising (x2test; x 2 = 0.476; p = 0.490). Statistically significant difference is confirmed in the age of patients at the diagnostic colonoscopy, depending on the reason for colonoscopy (F = 7.111; p = 0.000) in patients who were diagnosed polyps. Those with a family anamnesis and polyps were statistically significant younger in comparison to others except those who have come forward for review because of abdominal pain and bowel movement rhythm disturbances.There were no statistically significant differences by sex, age, the reason for colonoscopy in patients diagnosed with polyps.Statistically is more significant number of women with the localization of polyps in the distal part of the colon comparing to the proximal (x2test; x2 = 18,495; p = 0.000).In younger age groups are represented statistically significant polyps in the rectum (x2test; x2 = 79.963, p = 0.000). Subjects with proximal localization of polyps are 1,724 times more likely for high-risk adenomas compared to those with distal localization.No statistically significant differences in the distribution of cancer in relation to sex (x2test; x2 = 3.2110; p = 0.201).On the first postoperative colonoscopy in 1064 subjects there were a total 346 (32.5%) positive findings. 60 carcinoma diagnosed of which 43.3% is localized on the anastomosis and in 286 of the subjects had a total of 546 of the polyps.Men statistically significantly more likely to have positive findings (x2 test; x2 = 17,252; p = 0.000). Bonferroni post hoc test showed that polyps proximal localization significantly bigger than those in the rectum (p = 0.043). On the control colonoscopy-made for the purpose of monitoring after resection of colorectal cancer by multivariate analysis (sex, age and time of surgery) it has been found that men are 1.4 times more likely (OR = 1.457) than women for the occurrence of changes (polyps and cancers).Subjects having passed since the operation of 3 to 5 years are 1.6 times more likely to develop a change with respect to those in which the more than one year elapsed (OR = 1.605). CONCLUSION:In 24.3% subjects were diagnosed polyps (one hyperplastic and 21 adenomas).14.06% of all polyps had the characteristics of high-risk polyps with no statistically significant difference in the occurrence of polyps in subjects where the examination was done after 3,5 or 5 years since the first negative colonoscopy. No cancers diagnosed, meaning there is no need to repeat colonoscopy in a shorter period of time than pre-planned colonoscopy in subjects who had normal initial colonoscopy findings which refers to the repeated colonoscopies in subjects operated on for CRC.For diagnostic colonoscopy statistically significant number of women with the localization of polyps in the distal part of the colon compared to proximal and was not observed differences in the distribution of carcinoma in relation to sex and age of the subject.</p>

<p>Sve veća potreba za izvođenjem kolonoskopije u dijagnostičke ili terapijske svrhe nameće potrebu za usavr&scaron;avanjem ove endoskopske procedure. Izvođenje kolonoskopije u op&scaron;toj, intravenskoj anesteziji, moglo bi u značajnoj meri olak&scaron;ati njeno izvođenje, pobolj&scaron;ati podno&scaron;enje ove procedure od strane ispitanika i omogućiti otkrivanje većeg broja pacijenata sa potencijalno malignim bolestima debelog creva. Cilj ispitivanja je bio utvrditi da li primena op&scaron;te intravenske anestezije tokom kolonoskopije povećava broj totalnih kolonoskopija i skraćuje vreme intubacije cekuma, povećava broj viđenih patolo&scaron;kih procesa i smanjuje osećaj bola i učestalost neželjenih reakcija. Primena op&scaron;te intravenske anestezije značajno je povećala broj totalnih kolonoskopija u 94.3% ispitanika u odnosu na 78.7% totalnih kolonoskopija kontrolne grupe i skratila vreme intubacije cekuma, značajno je povećala broj viđenih patolo&scaron;kih promena u 46.7% ispitanika u odnosu na broj viđenih patolo&scaron;kih promena u 28.8% ispitanika kontrolne grupe i značajno je smanjila intenzitet bola i učestalost neželjenih reakcija. U kontrolnoj grupi ispitanika skalom bola nakon kolonoskopije ustanovljen je značajno veći intenzitet bola u poređenju sa ispitanicima ekperimentalne grupe. Na Likertovoj skali zadovoljstva ustanovljena je značajno bolja kontrola bola i lični stav lekara u ekperimentalnoj grupi, dok su poseta ustanovi i procedura, razumevanje procedure, tehnička ve&scaron;tina lekara, lični stav medicinskih sestara i drugog tehničkog osoblja značajno bolje ocenjeni u kontrolnoj grupi. Od svih ispitivanih faktora na zadovoljstvo obe grupe pacijenata značajno su uticali: način izvođenja procedure, bol, uočene patolo&scaron;ke promene i intubacija cekuma. U kontrolnoj grupi ispitanika između skale zadovoljstva i skale bola ustanovljena je značajna negativna korelacija. U kontrolnoj grupi se 80,1% pacijenata izjasnilo da bi ponovnu kolonoskopiju uradili u op&scaron;toj intravenskoj anesteziji u poređenju sa svim pacijentima eksperimentalne grupe koji ne bi menjali način izvođenja ponovne procedure. Primena op&scaron;te intravenske anestezije tokom kolonoskopije povećava broj totalnih kolonoskopija i uočenih patolo&scaron;kih promena, smanjuje učestalost i intenzitet neželjenih reakcija povećavajući zadovoljstvo pacijenata, &scaron;to bi prevashodno moglo imati značaja u skriningu karcinoma debelog creva. Potrebno je pro&scaron;iriti ispitivanje primene op&scaron;te intravenske anestezije u drugim endoskopskim procedurama kako bi bila uvedena u svakodnevnoj kliničkoj praksi.</p> / <p>An increasing need to perform colonoscopy for diagnostic or therapeutic purposes imposed the need for mastering this endoscopic procedure. Performing colonoscopy in general intravenous anesthesia could greatly ease the procedure, make it more comfortable for patients and it could enable detecting a higher number of patients with occult malignant diseases of the colon. The aim of this paper was to determine if the implementation of general intravenous anesthesia during colonoscopy increases the number of total colonoscopies and shortens the time of cecum intubation, increases the number of familiar pathological processes and decreases the sensation of pain as well as the frequency of side reactions. The implementation of general intravenous anesthesia has significantly increased the number of total colonoscopies in 94.3% of examined patients in relation to 78.7% of total colonoscopies of the control group and shortened the time of cecum intubation. It has significantly increased the number of familiar pathological changes in 46.7% of the patients in relation to the number of familiar pathological changes in 28.8% patients of the control group and significantly decreased pain intensity and the frequency of side reactions. A statistically greater pain intensity after colonoscopy was determined by the pain scale in the control group in comparison to the examinees of the experimental group. Likert satisfaction scale has shown that the experiment group assessed pain control and doctors&rsquo; opinion as significantly better, while the institution visits and the procedure, understanding the procedure, doctors&rsquo; technical skills, nurses&rsquo; and technical personnel&rsquo;s personal opinions were assessed as significantly better in the control group. Out of all the examined factors on the satisfaction of both groups, the following ones had a significant inluence: the way the procedure was done, the level of pain, detected pathological changes and cecum intubation. A significanlty negative correlation was determined between the scale of satisfaction and the scale of pain in the control group. 80.1% of the control group patients stated that they would undergo a general anesthesia colonoscopy again in comparison to all the patients of the experimental group who would not change the way the procedure was previously done. The implementation of general intravenous anesthesia in the course of colonoscopy increases the number of total colonoscopies and detected pathological changes, decreases the frequency and intensity of side-effects therefore it enhances patients&#39; sastisfaction, which could play a major role in colon cancer screening. It is necessary to extend the implementation of general intravenous anesthesia in other endoscopic procedures in order to introduce it in everyday clinical practice.</p>
