In this study, we investigated the relationship between the cecal intubation time (CIT) and the form and method used for passing through the sigmoid/descending colon junction (SDJ) and the hepatic flexure using an endoscopic position detection unit (UPD), with reference to various factors [age, sex, body mass index (BMI), history of abdominal and pelvic surgery, and diverticulum]. A total of 152 patients underwent colonoscopy with UPD. The mean age was 66.9 ± 12.4 years, and the male to female ratio was 3.6:1. The average CIT time was 14.3 ± 8.2 min. Age, number of experienced endoscopies, history of abdominal and pelvic surgery, BMI, and diverticulum were associated with prolonged CIT; SDJ passage pattern was straight: 8.6 ± 5.0, alpha loop: 11.8 ± 5.6, puzzle ring-like loop: 20.2 ± 5.0, reverse alpha loop: 22.4 ± 9.7, and other loop: 24.7 ± 10.5. The hepatic flexure passing method was in the following order: right rotation maneuver: 12.6 ± 6.6, push maneuver: 15.1 ± 5.9, and right rotation with positional change maneuver: 20.5 ± 7.2. In conclusion, colonoscopy with UPD revealed an association between CIT and SDJ passage pattern and hepatic flexure passing method.

The aim of this study was to evaluate the findings of CT scans in patients with pathologically confirmed primary colorectal squamous-cell carcinoma (SCC). The clinical presentation and CT findings in eight patients with pathologically confirmed primary colorectal squamous-cell carcinoma were retrospectively reviewed by two gastrointestinal radiologists. Hematochezia was the most common symptom (n = 5). The tumors were located in the rectum (n = 7) and sigmoid colon (n = 1). The tumors showed circumferential wall thickening (n = 4), bulky mass (n = 3), or eccentric wall thickening (n = 1). The mean maximal wall thickness of the involved segment was 29.1 mm ± 13.4 mm. The degree of tumoral enhancement observed via CT was well enhanced (n = 4) or moderately enhanced (n = 4). Necrosis within the tumor was found in five patients. The mean total number of metastatic lymph nodes was 3.1 ± 3.3, and the mean short diameter of the largest metastatic lymph node was 16.6 ± 5.7 mm. Necrosis within the metastatic node was observed in six patients. Invasions to adjacent organs were identified in five patients (62.5%). Distant metastasis was detected in only one patient. In summary, primary SCCs that arise from the colorectum commonly present as marked invasive wall thickening or a bulky mass with heterogeneous well-defined enhancement, internal necrosis, and large metastatic lymphadenopathies.

Meta-Analysis Comparative Study Review
BACKGROUND
Gangrenous sigmoid volvulus has a significant impact on morbidity and mortality. This study was conducted to compare sigmoid resection and primary anastomosis (RPA) with sigmoid resection and end colostomy (Hartmann's procedure) for gangrenous sigmoid volvulus.
METHODS
A systematic review and meta-analysis study design was employed to summarize retrospective cohort, prospective cohort, and randomised control trial studies published from inception to march 31, 2023. Searching was performed on Medline, CINAHAL, Web of Science, Google Scholar, the Cochrane Library, and ClinicalTrials.gov to locate eligible articles. Data searching, selection and screening, quality assessment of the included articles, and data extraction were done by two separate reviewers. RevMan 5.4 software with a fixed-effect Mantel-Haenszel model and Stata version 14 were used to analyze the data. The protocol registered on PROSPERO registration website (CRD42023413367).
RESULTS
Ten cohort studies and one randomised control trial with 724 patients were found; all of them were rated as being of moderate quality. The overall mortality after RPA was 15% (95%CI: 11-19%), and after Hartmann's procedure it was 19% (95%CI: 15-23%). Resection and primary anastomosis (RPA) for gangrenous sigmoid volvulus had slightly lower mortality rate than stoma (OR=0.98(95%CI: 0.68-1.42), p=0.07, I=43%), which had no statistically significant difference. Resection and primary anastomosis (RPA) had a slightly higher morbidity rate than Hartmann's procedure (OR=1.01(95%CI: 0.66-1.55), p=0.30, I=18%), which had no statistically significant difference.
CONCLUSION
Sigmoid resection and primary anastomosis (RPA) and Hartmann's procedure had no significant differences in mortality and morbidity for the treatment of gangrenous sigmoid volvulus. Choice of the intervention for gangrenous sigmoid volvulus should be individualized with consideration of different detrimental factors.

BACKGROUND
Laparoscopy is one of the major advances in surgery in the last 30 years and has many benefits. Although laparoscopy was initially used for resection of benign colon lesions, it is now widely used for colorectal cancer resections after strong evidence has confirmed its safety and efficacy. We aim to report both the surgical and oncological outcomes of our first series of laparoscopic colorectal cancer resections.
METHODS
In 2013, a laparoscopic colorectal resection service was established in northern Iraq at Zheen Hospital, Erbil. Data from all consecutive colorectal cancers were collected. Patients with locally advanced diseases and those who required emergency operations for bowel obstruction or perforation were excluded. We analyzed demographic, operative, postoperative, and histopathological data for all patients who were included in the study.
RESULTS
A total of 124 patients with colorectal cancers presented to our unit between January 2013 and January 2023. Only 112 patients fulfilled the inclusion criteria and underwent laparoscopic resections. The median age of the patients was 54.5 years. The majority of patients were men (n=62; 55.4%). In 39 patients (35%), the cancer was located in the sigmoid; in 33 patients (29.5%) the cancer was in the rectum. Laparoscopic anterior resection was the most common procedure (n=50; 45%), followed by right hemicolectomy in 17 cases (15.1%). The conversion rate to open surgery was 8% (nine cases). The most common causes of conversion to open surgery were dilated bowel loops and tumour adherence to other structures. The mean operative time was 190 minutes and the mean hospital stay was three days. No complications were reported in 94 patients (84%). Among the complications, wound infection was seen in seven patients (7.8%). There were six anastomotic leaks (6.7%). The mean number of lymph nodes harvested was 13. In 70 patients (62.5%), the lymph node count was ≥12 with a median of 13. The mean distal resection margin was 6 cm and 2.5 cm for colon and rectal resections, respectively.
CONCLUSION
This study reveals that laparoscopic resection for colorectal cancers is surgically practicable and safe with the benefits of a short hospital stay, adequate resection margins, and adequate lymph node yield.

Retrorectal herniation of the sigmoid colon is a rare condition characterized by the protrusion of a segment of the colon into the pre-sacral space and posterior to the rectum. This herniation occurs through a defect in the peritoneum, which may have developed secondary to congenital mechanisms, surgery, trauma, or inflammatory processes. Here, a case of retrorectal herniation of the sigmoid colon in an elderly female patient presenting with constipation is reported, with a review of the literature.

BACKGROUND
The incidence of colonic adenomas and colorectal cancer has been on the rise among young patients. In this study, we aimed to describe the characteristics of young patients (<50 years) with adenomatous polyps and to characterize those polyps. We also aimed to determine appropriate surveillance intervals for young patients.
METHODS
We performed a retrospective chart review of patients <50 years of age who had polypectomy of 1 or more adenomatous polyps on colonoscopy between 2008 and 2021. Patient demographics, colonoscopy indication and polyp characteristics were obtained from the chart. Timing and findings on surveillance colonoscopies were recorded.
RESULTS
A total of 610 patients were included: mean age 42.9±5.9 years, 61% males, body mass index 27.5±4.7 kg/m, and over 50% smokers. The most common indications were abdominal pain (23.3%), rectal bleeding (22.3%), and change in bowel habits (17.6%). Almost half of the patients who had adenomas (299) were younger than 45 years. Tubular adenoma was the most frequently encountered type of polyp (571; 93.6%). Mean polyp size was 1.1±0.9 cm. The most common location of adenomas was the sigmoid colon (41%). Of patients with adenomas, 156 (26%) had surveillance colonoscopy within 2.9±2.3 years; 74 patients (47.4%) were found to have new adenomas.
CONCLUSIONS
Patients aged <50 years with colonic adenomas were mostly males, overweight, and smokers. Further adenomas were found in 47% of surveillance colonoscopies, and most were encountered within 5 years. High rates of recurrent adenomas in people <50 years of age may warrant frequent surveillance.

Chronic intestinal schistosomiasis (CIS) refers to the long-term effects of infection with Schistosoma parasites in the intestines. This condition typically develops after repeated or prolonged exposure to contaminated freshwater containing Schistosoma eggs. The current study reports a case of an adult male, who complained of abnormal abdominal and anal pain for a month and had a medical history of complex perianal fistulae. The endoscopic investigation revealed different degrees of hyperemia, concentrated in the sigmoid colon and rectum. Lesions were localized in the rectum and sigmoid colon. Yellow granular hyperplasia, whether concentrated or dispersed, single or multiple polyps, along with observations of mucosal congestion, edema, faint vascular striations, erosions, superficial ulcers, and scattered petechial hemorrhages were noted. Also, the segmented areas of the colon had different degrees of inflammation. The microscopic histopathological analysis showed a culprit of surgical scar tissue. The granulomas harbored Schistosome parasites at the submucosal depth. Also, an erosion in the colonic mucosal tissues accompanied by lymphoplasmacytic and micro-abscess infiltrates was seen. A Schistosoma bilharzial ova was observed in the granuloma at the submucosal level. Endoscopic and histopathological investigations are useful tools to differentiate between CIS and Crohn's disease. These tools can distinguish CIS from Crohn's disease. Early detection and treatment are essential to prevent the progression of the disease and minimize long-term complications.

A 72-year-old woman with a prior sigmoid resection for colon cancer underwent a right hemicolectomy after a colonoscopy revealed a mass in the hepatic flexure. A preoperative biopsy at colonoscopy showed tubulovillous dysplasia with high-grade neoplasm. The final specimen pathology revealed benign mucosal elements with mucin pools consistent with colitis cystica profunda (CCP). CCP is a benign lesion; no further treatment was necessary after resection. To our knowledge, this is the first reported case of CCP in the right colon, presenting atypically in the hepatic flexure. This case report brings to light the difficulty and importance of making an accurate diagnosis of CCP.

This case report presents a rare complication of hepatic cystic echinococcosis in a 12-year-old Latino male, residing in a nonendemic region, who developed long-term sequelae of portal vein thrombosis accompanied by the emergence of a hyper-vascular sigmoid colon mass. Portal vein involvement in hepatic cystic echinococcosis is exceedingly uncommon, with limited documented cases. The presentation of the patient included intermittent hematochezia, abdominal pain, and fatigue. Imaging revealed liver cysts and chronic portal vein thrombosis with cavernous transformation, resulting in portal hypertension. Notably, the patient also exhibited mesenteric venous thrombosis, further complicating the clinical picture. The diagnosis was confirmed through echinococcus serology testing. Treatment involved a six month course of Albendazole, puncture-aspiration-injection-reaspiration procedure, splenectomy, and splenorenal shunt to alleviate portal hypertension. This case underscores the significance of considering portal hypertension secondary to hepatic cystic echinococcosis, even in nonendemic regions, particularly in pediatric patients with unique clinical presentations.

BACKGROUND/AIMS
Patients of ulcerative colitis (UC) on follow-up are routinely evaluated by sigmoidoscopy. There is no prospective literature to support this practice. We assessed agreement between sigmoidoscopy and colonoscopy prospectively in patients with disease extent beyond the sigmoid colon.
METHODS
We conducted a prospective observational study at a tertiary care institute for agreement between sigmoidoscopy and colonoscopy. We assessed endoscopic activity using the Mayo Endoscopic Score (MES) and Ulcerative Colitis Endoscopic Index of Severity (UCEIS) and histological activity using the Nancy Index (NI), Robarts Histopathology Index (RHI), and Simplified Geboes Score (SGS).
RESULTS
Sigmoidoscopy showed a strong agreement with colonoscopy for MES and UCEIS with a kappa (K) of 0.96 and 0.94 respectively. The misclassification rate for MES and UCEIS was 3% and 5% respectively. Sigmoidoscopy showed perfect agreement (K = 1.00) with colonoscopy for assessment of the presence of endoscopic activity in the colon using MES ??1 as activity criteria and strong agreement (K = 0.93) using MES > 1 as activity criteria. Sigmoidoscopy showed strong agreement with colonoscopy for assessment of the presence of endoscopic activity using UCEIS (K = 0.92). Strong agreement was observed between sigmoidoscopy and colonoscopy using NI (K = 0.86), RHI (K = 1.00), and SGS (K = 0.92) for the detection of histological activity. The misclassification rate for the detection of histological activity was 2%, 0%, and 1% for NI, RHI, and SGS respectively.
CONCLUSIONS
Sigmoidoscopy showed strong agreement with colonoscopy for endoscopic and histologic disease activity. Sigmoidoscopy is adequate for assessment of disease activity in patients with UC during follow-up evaluation.
