OBJECTIVE: to evaluate the effect of bacterial colonization on ureteral stent-associated morbidity. METHODS: This was a prospective study that took place between February 2019 and March 2022. We examined one hundred fifteen patients for ureteric stents application. On the same day of stent removal, the Arabic version of Ureteral Stent Symptoms Questionnaire (USSQ) was used to assess stent-associated morbidity. The stent-associated morbidity and the specificity and sensitivity of culture in the stent and midstream urine were recorded...

OBJECTIVE: To analyze available literature data on the methods of colon recanalization in patients with acute malignant obstructive colonic obstruction. MATERIAL AND METHODS: We retrospectively analyzed literature data on the treatment of acute neoplastic colonic obstruction. RESULTS: We reviewed available national and foreign literature data on various methods of colon recanalization including various modern and hybrid techniques. CONCLUSION: Methods of colon recanalization with subsequent stenting are the most optimal for preoperative decompression of colon...

The therapy of left-sided malignant colonic obstruction continues to be one of the largest problems in clinical practice. Numerous studies on colonic stenting for neoplastic colonic obstruction have been reported in the last decades. Thereby the role of self-expandable metal stents (SEMS) in the treatment of malignant colonic obstruction has become better defined. However, numerous prospective and retrospective investigations have highlighted serious concerns about a possible worse outcome after endoscopic colorectal stenting as a bridge to surgery, particularly in case of perforation...

AIM: Elective stoma formation has a negative effect on patient quality of life (QoL), with a potential detrimental impact on body image, confidence and social functioning being shown previously. However, the impact of emergency stoma formation on QoL has been explored less frequently. This systematic review aims to synthesize all available literature exploring QoL via patient-reported outcome measures. METHODS: A search strategy was implemented on 24 November 2022 across Embase, MEDLINE, PsycInfo and the Cochrane Library database after registration on PROSPERO (CRD42022370606)...

We report a rare case of gastric cancer presenting with a gastrocolic fistula during ramucirumab and paclitaxel combination therapy that was successfully managed with colonic stenting. A 75-year-old man was admitted to our hospital with the chief complaint of melena. Esophagogastroduodenoscopy revealed a large ulcerated tumor in the lower stomach, judged by laparoscopy as unresectable (sT4bN1M0). After four cycles of first-line chemotherapy with S-1 plus oxaliplatin, the patient showed disease progression, and second-line therapy with ramucirumab and paclitaxel was started...

BACKGROUND: During the recent 2-year quarantine, the coronavirus disease 2019 (COVID-19) pandemic changed the course of medical treatment and posed some new challenges to the care of particularly vulnerable oncology patients. Despite the re-purposing of The Second University Clinic (Sechenov University), we still admitted many patients with colonic obstruction. The endoscopic unit was situated in a separate facility, but due to the intensive use of all of our X-ray equipment for COVID-19 patients, the question arose about the possibility of placing a stent without fluoroscopic control...

Ureteral stents are useful devices in urological surgery. The main objective of a ureteric stent is to allow passage of urine and reduce early or late complications related to obstruction in the urinary tract. Despite their widespread use, there is a general lack of knowledge and awareness in stent composition and indication of application. We represented a synthesis of our extensive research over materials, coatings and shapes available on the market and then analyzed the main characteristics and peculiarities of ureteral stents...

A man in his seventies was referred to our hospital for radical therapy for advanced rectal cancer with multiple liver metastases. A colonic stent had already been placed in his rectum at the previous hospital because of malignant colorectal obstruction, so our therapeutic strategy was to perform systematic chemotherapy after resection of the primary tumor. Laparoscopic low anterior resection with a covering stoma was performed under general anesthesia. At about one hour after the surgery, the patient had sudden abdominal pain with watery diarrhea, and a similar discharge from his drainage tube...

Since the development of the fiberoptic colonoscope in the late 1960s, colonoscopy has been a useful tool to diagnose and treat various intestinal diseases. This article reviews the clinical use of colonoscopy for various intestinal diseases based on present and future perspectives. Intestinal diseases include infectious diseases, inflammatory bowel disease (IBD), neoplasms, functional bowel disorders, and others. In cases of infectious diseases, colonoscopy is helpful in making the differential diagnosis, revealing endoscopic gross findings, and obtaining the specimens for pathology...

BACKGROUND: A neurofibroma is a benign tumor that arises from Schwann cells and neurofibromas occur throughout the skin of neurofibromatosis type 1 (NF-1: Von Recklinghausen's disease) patients. A retroperitoneal solitary neurofibroma without any clinical signs of NF1 has been rarely reported. Herein, we present a case of a retroperitoneal solitary neurofibroma mimicking lymph node metastasis of colon cancer as well as a literature review. CASE PRESENTATION: An 80-year-old woman with abdominal pain and nausea was transported and diagnosed with bowel obstruction arising from sigmoid colon cancer A colonic stent was inserted to alleviate the bowel obstruction...

BACKGROUND: Several management options exist for colonic decompression in the setting of malignant large bowel obstruction, including oncologic resection, surgical diversion, and SEMS as a bridge-to-surgery. Consensus has yet to be reached on optimal treatment pathways. The aim of the present study was to perform a network meta-analysis comparing short-term postoperative morbidity and long-term oncologic outcomes between oncologic resection, surgical diversion, and self-expanding metal stents (SEMS) in left-sided malignant colorectal obstruction with curative intent...

AIM: To evaluate the operative and oncological results after colonic stent bridging for left-sided malignant large bowel intestinal obstruction and the risk factors for survival and recurrence after definitive surgery. METHODOLOGY: Consecutive patients who underwent colonic stenting for malignant left-sided colonic obstruction were included. Patients for palliative stenting or emergency surgery, patient with low rectal tumour or peritoneal metastasis were excluded...

AIM: The aim of this study was to investigate the trends in morbidity and mortality of patients with right-sided colonic cancer who had an emergency surgical procedure in Denmark after the introduction of quality index parameters. METHODS: This was a retrospective nationwide study based on a prospectively maintained Danish Colorectal Cancer Group database focused on right-sided colonic cancer in the interval from 1 May 2001 to 30 April 2018, who underwent emergency surgical intervention (within 48 h of hospital admission)...

BACKGROUND: Colorectal cancer (CRC) metastasis commonly occurs in the liver and lungs with bone metastasis rarely occurring in isolation. Disseminated carcinomatosis of bone marrow (DCBM) is extremely rare in CRC. We conducted a systematic review to provide more information on the diagnosis, treatment options, and prognosis of the condition. METHODS: Studies were identified by performing searches on MEDLINE and EMBASE electronic databases according to the PRISMA statement standards...

Cowden syndrome is characterized by several clinical features related to tumorous lesions primarily consisting of systemic hamartomas. The mutation of a tumor suppressor gene, the PTEN gene, is etiologically involved. As gastrointestinal lesions, polyps of all digestive tracts involving the esophagus to rectum develop. In patients with Cowden syndrome, the risk of colorectal cancer may increase. However, the characteristics of colorectal cancer in these patients remain to be clarified and sufficient findings regarding chemotherapy have not been obtained...

A 73-year-old woman was admitted with a chief complaint of weight loss. Colonoscopy revealed rectal cancer. After the placement of a colonic stent, the patient was referred to our department. Computed tomography, magnetic resonance imaging, and cystoscopy indicated extensive invasion of the bladder. Since total pelvic exenteration was necessary at the first diagnosis, total neoadjuvant therapy(TNT)was conducted. The diagnosis after TNT was ycT4bycN0ycM0. Low anterior resection with partial resection of the bladder and a diverting ileostomy were performed...
