Risk Nomogram Does Not Predict Anastomotic Leakage After Colon Surgery Accurately: Results of the Multi-center LekCheck Study

Introduction. One of the most common and serious complications of near-postoperative surgery after colon resection with anastomosis is intestinal leakage with a frequency of 1 to 24%. Therefore, it is very important to evaluate the factors that may determine the development of this complication. One of the etiological factors behind the development of this complication is the intestinal microbiota, which is playing an increasingly important role in this process. Nevertheless, there is still a lack of comprehensive clinical evidence on the influence of the intestinal microbiota on postoperative complications such as anastomotic leakage. Purpose. To evaluate the influence of intestinal microorganisms on anastomotic leakage after elective intestines surgery. Methods. A prospective study was performed at the Lithuanian University of Health Sciences Hospital, Kaunas Clinics, Clinic of Surgery. There were included patients who underwent colon surgery (right hemicolectomy, left hemicolectomy, sigmoid resection and closure of ileostomy). Intestinal mucosal biopsy performed before restoring intestinal integrity and sent for microbiological and antibiotic examination. Patients were also observed postoperatively for anastomotic leakage. Results. The majority of patients were treated for colon cancer – 46 (92.0%). In 19 patients crop (38.0%) grown one microorganism, in 12 (24.0%) – 2 microorganisms, in 5 (10.0%) – 3 microorganisms, in 1 (2.0%) – 4 types of bacteria. In the most of the crops were observed growth by E. coli – 30 (60.0%), Enterococcus spp. – 12 (24.0%), Bacteroides spp. – 4 (8.0%), Klebsiella oxytoca – 2 (4.0%), Beta hemolytic streptococcus – 2 (4.0%) patients. Citrobacter fundii, Citrobacter brakii, Parabacteroides distasonis, Proteus mirabilis, Klebsiella pneumoniae, Enterobacteriaceae daacea grew only in 1 (2.0%) patients crop. Postoperative anastomotic leakage diagnosed in 2 (4.0%) patients. Conclusions. The major microorganisms that grown were E. coli. Due to the small sample, tendency can not be predicted, but microorganisms that promote small blood vessels thrombosis may be one of the factors that cause anastomotic leakage.

Abstract Introduction The optimal preoperative preparation for elective colorectal cancer surgery has been debated in academic circles for decades. Previously, many expert teams have conducted studies on whether preoperative mechanical bowel preparation and preoperative oral antibiotics can effectively reduce the incidence of postoperative complications, such as surgical site infections and anastomotic leakage. Most of the results of these studies have suggested that preoperative mechanical bowel preparation for elective colon surgery has no significant effect on the occurrence of surgical site infections and anastomotic leakage. Methods/design This study will examine whether oral antibiotic bowel preparation (OABP) influences the incidence of anastomotic leakage after surgery in a prospective, multicentre, randomized controlled trial that will enrol 1500 patients who need colon surgery. The primary endpoint, incidence of anastomotic leakage, is based on 2.3% in the OABP ± mechanical bowel preparation (MBP) group in the study by Morris et al. The patients will be randomized (1:1) into two groups: the test group will be given antibiotics (both neomycin 1 g and metronidazole 1 g) the day before surgery, and the control group will not have any special intestinal preparation before surgery, including oral antibiotics or mechanical intestinal preparation. All study-related clinical data, such as general patient information, past medical history, laboratory examination, imaging results, and surgery details, will be recorded before surgery and during the time of hospitalization. The occurrence of postoperative fistulas, including anastomotic leakage, will be recorded as the main severe postoperative adverse event and will represent the primary endpoint. Ethics and dissemination Ethics and dissemination Ethics approval has been obtained from the Ethics Committee at the Chinese Ethics Committee of Registering Clinical Trials(ChiECRCT20200173). The results of this study will be disseminated at several research conferences and as published articles in peer-reviewed journals. Trial registration: ChiCTR2000035550. Registered on 13 Aug 2020.

Laparoscopic Hemicolectomy

Összefoglaló. Bevezetés: A laparoszkópia térhódítása a jobb oldali colon műtéteknél is nyilvánvaló. Ma legtöbb helyen a laparoszkóposan asszisztált jobb oldali hemikolektómia extrakorporális anasztomózissal a gold standard. A morbiditás randomizált vizsgálatok alapján még 30% körüli. A technikai fejlődés lehetővé tette az intrakorporális anasztomózist. Célkitűzés: Retrospektív módon elemezni rosszindulatú jobb oldali vastagbéldaganat miatt végzett laparoszkópos hemikolektómiák rövid távú eredményeit a két módszer összehasonlításával. Eredmények: 2018. 01. 01. – 2019. 12. 31. között 184 jobb oldali hemikolektómiát végeztünk, ezek közül 122 történt malignus betegség miatt. 51 esetben nyitott és 71 esetben laparoszkópos műtét történt. 37 férfi (átlagéletkor: 70,59 év) és 34 nő (átlagéletkor: 72,14 év) volt. 50 esetben extrakorporális (EA) és 21 esetben pedig intrakorporális anasztomózist (IA) végeztünk. Az EA csoportban 18, míg az IA csoportban 3 szövődmény alakult ki 30 napon belül (p = 0,067). Az EA csoportból 3, az IA csoportból 1 beteget veszítettünk el 30 napon belül (p = 0,66). Az átlagos ápolási idő az EA csoportban 9,48 (5–32) nap, míg az IA csoportban 6,52 (4–19) nap volt (p = 0,001) a szövődményes esetekkel együtt. A szövődményes esetek nélkül az EA csoportban 6,35 (5–10) nap, az IA csoportban pedig 5,55 (4–8) napnak bizonyult (p = 0,09). A műtéti idő pedig az EA csoportban 147 (90–240) perc, az IA csoportban pedig 146,47 (90–265) perc volt (p = 0,11). Konklúzió: Az irodalommal összhangban azt találtuk, hogy IA esetén kevesebb a szövődmény, ezzel is összefüggésben rövidebb az átlagos ápolási idő, és a műtéti időt tekintve nincs szignifikáns különbség. Ezeket figyelembe véve az intrakorporális anasztomózis javasolható jobb oldali laparoszkópos hemikolektómia esetén. Summary. Introduction: Laparoscopy became evident for right-sided colon surgery too. Today the laparoscopic-assisted right-hemicolectomy is the gold standard with extracorporeal anastomosis. Morbidity according to randomized trials is still approximately 30%. The development of the surgical technique resulted in the creation of intracorporeal anastomosis. Our aim was to compare the short-term results of the two methods. Aim: To analyse the short-term results of right-sided hemicolectomy that were performed due to malignant tumours with the comparison of the two methods. Results: A cohort of 184 right-sided hemicolectomy were performed from 01.01.2018 to 31.12.2019 from which 122 were operated on because of a malignant disease. 51 open and 71 laparoscopic operations were performed. The average age of 37 men and 34 women were 70.59 and 72.14 years, respectively. 50 patients underwent extracorporeal (EA) anastomosis and 21 intracorporeal (IA) anastomosis. Within 30 days the number of complications were 18 in the EA group and 3 in the IA group (p = 0.067). 3 from the EA group and 1 from IA group died within 30 days (p = 0.66). The average length of stay were 9.48 days in the EA group and 6.52 days in the IA group together with the complicated cases (p = 0.001) while 6.35 days and 5.55 days without the complicated cases (p = 0.09). The average duration of operation was 147 minutes in the EA and 146.47 minutes in the IA group (p = 0.11). Conclusion: We found concordance with the literature that there are fewer complications in case of IA which might be related to shorter length of stay. There is no significant difference between the surgical times. Bearing these facts in mind, IA might be suggested for right- sided laparoscopic hemicolectomy.
