Colonic diverticula develop at specific weak spots, where the vasa recta enter the colonic circular smooth muscle layer.1 They are usually seen in the left colon. Their most common complication is diverticulitis, with mild cases resolving even without antibiotic therapy.2 Right-side diverticulitis develops in only 1.5% of cases, primarily on the anterior aspect of the cecum, proximal to the ileocecal valve (80%).4 Given its low incidence, location, and the fact that it involves younger patients, a differential diagnosis is needed to rule out abdominal inflammatory conditions such as appendicitis or ileitis, as well as gynecological disorders. Diverticulitis is diagnosed using imaging modalities. Computed tomography (CT) is the modality of choice,5 and confirmation is required after clinical remission, primarily using colonoscopy. We studied a series of 3 cases of patients initially diagnosed with acute, uncomplicated right-side diverticulitis who were admitted to the Gastroenterology Department, Hospital de León, from January to December 2023. Our goal was to confirm a presumptive diagnosis of right-side diverticulitis using delayed endoscopy or barium enema to ascertain the presence of right-side diverticulosis and rule out other conditions manifesting with abdominal pain in the right iliac fossa. Cases 1 and 3 were admitted with an accurate diagnosis of right-side diverticulitis. Case 1 was confirmed by ambulatory colonoscopy, and case 3 was confirmed by barium enema because of a history of previous colonoscopy without findings. All three patients required surgical assessment to rule out appendicular involvement. The imaging technique of choice was CT, using the WSES scale for severity grading. Case 2 was diagnosed with right-side diverticulitis by means of ultrasonography, and its origin was later confirmed to be in the sigmoid colon. The remaining clinical, laboratory, and diagnostic characteristics are listed in Table 1.

Review
The standard diagnostic modalities for gastrointestinal (GI) diseases have long been endoscopy and barium enema. Recently, trans-sectional imaging modalities, such as computed tomography and magnetic resonance imaging, have become increasingly utilized in daily practice. In transabdominal ultrasonography (US), the bowel sometimes interferes with the observation of abdominal organs. Additionally, the thin intestinal walls and internal gas can make structures difficult to identify. However, under optimal US equipment settings, with identification of the sonoanatomy and knowledge of the US findings of GI diseases, US can be used effectively to diagnose GI disorders. Thus, the efficacy of GIUS has been gradually recognized, and GIUS guidelines have been published by the World Federation for Ultrasound in Medicine and Biology and the European Federation of Societies for Ultrasound in Medicine and Biology. Following a systematic scanning method according to the sonoanatomy and precisely estimating the layered wall structures by employing color Doppler make diagnosing disease and evaluating the degree of inflammation possible. This review describes current GIUS practices from an equipment perspective, a procedure for systematic scanning, typical findings of the normal GI tract, and 10 diagnostic items in an attempt to help medical practitioners effectively perform GIUS and promote the use of GIUS globally.

Chilaiditi's sign (colonic interposition) is a rare anomaly due to an abnormally located portion of the colon that is interposed in between the liver and the diaphragm. This rare anomaly is often incidentally seen on chest or abdominal radiographs. Chilaiditi's radiographic sign is usually asymptomatic, whereas the medical condition accompanied by clinical symptoms is termed Chilaiditi's syndrome. Possible causes of the syndrome include a long and mobile colon, scarring of the liver (cirrhosis), ascites, long-standing lung disease, as well as laxity of the falciform ligament. The most common clinical signs of Chilaiditi's syndrome include gastrointestinal symptoms; however, clinical presentation can vary. This report describes a case of a 21-year-old male patient who presented with a longstanding history of left upper quadrant epigastric abdominal pain with diarrhea (six to eight loose watery stools). The patient was diagnosed with Crohn's colitis and had tried a myriad of medical therapies with no adequate response. He chose to seek a second opinion and was subsequently discovered to have Chilaiditi's syndrome via computed tomography (CT) and confirmed by barium enema. The patient then elected to undergo a right laparoscopic colectomy to resolve the symptoms. By postoperative day five, all symptoms had resolved including abdominal pain and diarrhea. Therefore, it is important to consider Chilaiditi's syndrome as a differential diagnosis in persons presenting with left upper quadrant pain and symptoms of Crohn's colitis, especially those treated with adequate medical therapy without alleviation of symptoms.

Review
Colorectal cancer is the 3rd leading cause of cancer-related deaths in Korea, ranking 4th and 3rd among men and women, respectively. It is also the most common cause of cancer-related deaths in women older than 64 years. This study assessed the National Cancer Screening Program for colorectal cancer and examined its efficacy in enhancing public health. The fecal occult blood test (FOBT), a traditional noninvasive colorectal cancer screening test that can be performed on an outpatient basis was replaced with the fecal immunochemical test (FIT) because of the latter's better predictive value. Since 2004, the Government of South Korea has recommended an annual FIT for people aged 50 years and older as the first step in colorectal cancer screening. Individuals who test positive on the FIT are scheduled for follow-up screening procedures, such as colonoscopy or double-contrast barium enema, whereas those who have a negative FOBT are not recommended for colonoscopy. Colonoscopy, as a screening tool in Korea, has definite merits because it is highly accessible to patients and is performed by qualified specialists. Although the domestic colorectal cancer screening rate is relatively stable, there is scope for improvement. Owing to the low cost of colonoscopy and the wealth of skilled endoscopy specialists, the number of intention-to-screen procedures for colonoscopy has increased. As Korea is rapidly becoming an ultra-elderly society, it is time to reconsider the revision of the classical screening program and recommend region-specific, cost-effective guidelines.

Review
Lower gastrointestinal endoscopy is considered the gold standard for the diagnosis and removal of colonic polyps. Delays in colonoscopy following a positive fecal immunochemical test increase the likelihood of advanced adenomas and colorectal cancer (CRC) occurrence. However, patients may refuse to undergo conventional colonoscopy (CC) due to fear of possible risks and pain or discomfort. In this regard, patients undergoing CC frequently require sedation to better tolerate the procedure, increasing the risk of deep sedation or other complications related to sedation. Accordingly, the use of CC as a first-line screening strategy for CRC is hampered by patients' reluctance due to its invasiveness and anxiety about possible discomfort. To overcome the limitations of CC and improve patients' compliance, several studies have investigated the use of robotic colonoscopy (RC) both in experimental models and in vivo. Self-propelling robotic colonoscopes have proven to be promising thanks to their peculiar dexterity and adaptability to the shape of the lower gastrointestinal tract, allowing a virtually painless examination of the colon. In some instances, when alternatives to CC and RC are required, barium enema (BE), computed tomographic colonography (CTC), and colon capsule endoscopy (CCE) may be options. However, BE and CTC are limited by the need for subsequent investigations whenever suspicious lesions are found. In this narrative review, we discussed the current clinical applications of RC, CTC, and CCE, as well as the advantages and disadvantages of different endoscopic procedures, with a particular focus on RC.

Diagnostic accuracy of barium enema versus full-thickness rectal biopsy in children with clinically suspected Hirschsprung's disease: A comparative cross-sectional study.
BACKGROUND AND AIMS
Hirschsprung's disease (HSD) remains a common cause of pediatric intestinal obstruction. Barium contrast enema (BE) is the primary imaging modality for the evaluation of clinically suspected cases. Here, we aimed to assess the diagnostic accuracy of BE in children with clinically suspected HSD when compared to a gold standard full-thickness rectal biopsy (FTRB).
METHODS
We recruited and consecutively enrolled children with clinically suspected HSD at two tertiary teaching hospitals. Participants underwent BE imaging and two radiologists interpreted the findings independently. Participants further underwent FTRB by pediatric surgeons as the confirmatory test. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and receiver operating characteristics (ROC) with the area under the curve (AUC) were calculated on Stata version 14.2, taking FTRB as the standard.
RESULTS
We enrolled 55 cases, of which 49 completed the evaluation and were included in the final analysis. The median age was 9.4 months (interquartile range: 2-24], with a male-to-female ratio of 4.4:1. The sensitivity, specificity, PPV, and NPV of BE were 0.95 (95% confidence interval [CI] [0.81-0.99]), 0.73 (95% CI [0.39-0.94]), 0.92 (95% CI [0.82-0.97]), and 0.80 (95% CI [0.50-0.94]), respectively. On AUC, the diagnostic accuracy of BE compared to the confirmatory FTRB was 0.84 (95% CI [0.69-0.98]). The diagnostic accuracy was higher in neonates (ROC: 1.00) when compared to infants (ROC: 0.83) or those above 1 year of age (ROC: 0.798). HSD-suggestive BE findings were associated with absence of ganglion cells on FTRB ( = 23.301, < 0.001). Inverted rectosigmoid ratio and transition zone were more sensitive in detecting HSD of 0.92 (95% CI [0.74-0.98]) and 0.81 (95% CI [0.63-0.92]), respectively.
CONCLUSION
BE is sufficiently accurate in the diagnosis of children with HSD, suggesting BE would likely be used to inform surgical management in settings where confirmatory biopsy is lacking. However, clinical judgment is warranted in interpreting negative BE findings.

INTRODUCTION
The incidence of colonic diverticulosis has risen significantly. Diverticular disease is the most frequent cause of colovesical fistulas, which are uncommon complications of diverticulitis. Clinical signs, such as fecaluria and pneumaturia, are typically required to confirm its presence. Finding the cause of the disease so that the proper therapy can be started is the primary goal of a diagnostic workup rather than observing the fistula tract itself. . We present a 43-year-old man complaining of frequent urinary tract infections for six months. On CT abdomen and pelvis, a colovesical fistula was diagnosed. Surgery was performed, and after the division between the sigmoid colon and the bladder, a sigmoidectomy and an end-to-end colorectal anastomosis were performed. During the surgery, the fistula tract was not detected. The patient was discharged in excellent condition on day six, and the catheter was removed on day 10.
CONCLUSION
In conclusion, as in our case, any patient with a urinary tract infection should be suspected of having this condition, especially if he has persistent symptoms that have not responded to standard medical care. Patients who present with fecaluria, pneumaturia, and other specific symptoms of a colovesicular fistula do not necessarily need a barium enema or cystography to confirm the presence of the fistula.
