Randomized Controlled Trial
INTRODUCTION
Colorectal Cancer (CRC) is the third most common malignant disease and the fourth most common cause of death associated with malignancy. Adenocarcinomas account for 95% of all cases of colon cancer. Treatment usually includes a surgical resection which is preceded or followed by chemotherapy and radiotherapy depending on the stage. There is constant interest in the microbiological ecosystem of the intestine, which is considered to be crucial for the onset and progression of the disease as well as the development of postoperative complications. Iatrogenic factors associated with the treatment of CRC may result in pronounced expression of virulence of the bacterial intestinal flora and fulminant inflammatory response of the host which ultimately leads to adverse treatment results. The modulation of intestinal microflora by probiotics seems to be an effective method of reducing complications in surgical patients. The question is whether ordering probiotics can lead to more favourable treatment outcomes for our patients who are operated due to colorectal adenocarcinoma, and whether this should become common practice.
AIM
To demonstrate the clinical significance of probiotic administration in patients treated for colorectal adenocarcinoma and the results compared with relevant studies.
PATIENTS AND METHODS
In a randomized controlled prospective study conducted at the Clinic of General and Abdominal Surgery of the UCCS in the period of 01 January 2017 until 31 December 2017, there were a total of 78 patients with colorectal adenocarcinoma. Patients were divided into two groups: a group treated with oral probiotics (n = 39) according to the 2x1 scheme starting from the third postoperative day lasting for the next thirty days, followed by 1x1 lasting for two weeks in each subsequent month to one year, and the control group (n = 39) which was not routinely treated with probiotics.
RESULTS
A statistically significant difference in the benefit of using probiotics was found during postoperative hospitalization and the occurrence of fatal outcome in the first six months. All complications were more present in the group of patients untreated with probiotic, with statistical significance shown only in the case of ileus. Probiotic has a statistically significant reduction in postoperative complications in the localization of tumours on the rectum -33.3% and the ascending colon -16.7%.
CONCLUSION
There is a significant benefit of administering probiotics in surgically treated patients for colorectal adenocarcinoma.

BACKGROUND
Complete mesocolic excision is gradually becoming an established oncologic surgical principle for right hemicolectomy. However, the procedure is technically demanding and carries the risk of serious complications, especially when performed laparoscopically. A standardized procedure that minimizes technical hazards and facilitates teaching is, therefore, highly desirable.
METHODS
An expert group of surgeons and one anatomist met three times. The initial aim was to achieve consensus about the surgical anatomy before agreeing on a sequence for dissection in laparoscopic CME. This proposal was evaluated and discussed in an anatomy workshop using post-mortem body donors along with videos of process-informed procedures, leading to a definite consensus.
RESULTS
In order to provide a clear picture of the surgical anatomy, the "open book" model was developed, consisting of symbolic pages representing the corresponding dissection planes (retroperitoneal, ileocolic, transverse mesocolic, and mesogastric), vascular relations, and radicality criteria. The description of the procedure is based on eight preparative milestones, which all serve as critical views of safety. The chosen sequence of the milestones was designed to maximize control during central vascular dissection. Failure to reach any of the critical views should alert the surgeon to a possible incorrect dissection and to consider converting to an open procedure.
CONCLUSION
Combining the open-book anatomical model with a clearly structured dissection sequence, using critical views as safety checkpoints, may provide a safe and efficient platform for teaching laparoscopic right hemicolectomy with CME.

We report the case of a 65-year-old male patient with Down's syndrome and a deep venous thrombosis on anticoagulation with acenocoumarol. The case presented due to nonspecific, predominantly postprandial epigastric discomfort, meteorism and aerophagia. A thoracoabdominal computed tomography (CT) scan revealed a Morgagni hernia with a cephalad migration of part of the stomach, ascending colon and transverse colon. After laparotomy, the defect was repaired using a titanium mesh and the patient had a favorable outcome.

INTRODUCTION
Early-onset colorectal cancer diagnosed before the age of 50 years has been increasing. Likely reflecting the pathogenic role of the intestinal microbiome, which gradually changes across the entire colorectal length, the prevalence of certain tumor molecular characteristics gradually changes along colorectal subsites. Understanding how colorectal tumor molecular features differ by age and tumor location is important in personalized patient management.
METHODS
Using 14,004 cases with colorectal cancer including 3,089 early-onset cases, we examined microsatellite instability (MSI), CpG island methylator phenotype (CIMP), and KRAS and BRAF mutations in carcinomas of the cecum, ascending colon, transverse colon, descending colon, sigmoid colon, and rectum and compared early-onset cases with later-onset cases.
RESULTS
The proportions of MSI-high, CIMP-high, and BRAF -mutated early-onset tumors were lowest in the rectum (8.8%, 3.4%, and 3.5%, respectively) and highest in the ascending colon (46% MSI-high; 15% CIMP-high) or transverse colon (8.6% BRAF -mutated) (all Ptrend <0.001 across the rectum to ascending colon). Compared with later-onset tumors, early-onset tumors showed a higher prevalence of MSI-high status and a lower prevalence of CIMP-high status and BRAF mutations in most subsites. KRAS mutation prevalence was higher in the cecum compared with that in the other subsites in both early-onset and later-onset tumors ( P < 0.001). Notably, later-onset MSI-high tumors showed a continuous decrease in KRAS mutation prevalence from the rectum (36%) to ascending colon (9%; Ptrend <0.001), followed by an increase in the cecum (14%), while early-onset MSI-high cancers showed no such trend.
DISCUSSION
Our findings support biogeographical and pathogenic heterogeneity of colorectal carcinomas in different colorectal subsites and age groups.

A 76-year-old woman with significant cardiovascular comorbidities was investigated under general surgery for weight loss and change in bowel habit. Endoscopic investigations revealed a large ulcer extending from the ileocaecal valve to the ascending colon. Histology of the biopsies from this site revealed chronic inflammation and reactive changes. However, considering the history and suspicious radiological and endoscopic findings, decision was made at a multidisciplinary meeting to offer laparoscopic right hemicolectomy. Owing to complications, the procedure was converted to an open surgery. Postoperatively, histology of resected bowel revealed chronic inflammation and no evidence of malignancy. In light of an 8-year history of nicorandil therapy, the histological changes were thought to represent nicorandil-induced colonic ulceration.

INTRODUCTION
Colonic volvulus is the torsion of a part of the colon causing large bowel obstruction by strangulation, which may lead to ischemia and then necrosis. Synchronous colonic volvulus is extremely rare; even if there are some case reports on synchronous colonic volvulus, there are no reported cases of synchronous ascending and transverse colon volvulus in the medical literature to our knowledge.
CASE PRESENTATION
A 25-year-old girl with a previous history of epilepsy presented with a one-day duration of abdominal cramps with associated symptoms of vomiting of bilious matter, failure to pass faeces, and flatus of the same duration. The patient underwent surgical intervention, and ascending and transverse volvulus were discovered.
CONCLUSION
In spite of ascending and transverse colon volvulus rarity, we advised including these in the differential diagnosis of patients associated with large bowel obstruction.
