IBD-Disk as a tool estimating the prevalence of inflammatory bowel disease-related disability and associated influencing factors in Saudi Arabia: A cross-sectional study.

Background: Inflammatory bowel disease (IBD) disk is an easy tool to use in clinical practice to measure IBD-related disability, with a score >40 correlating with high daily-life burden. Its use has been limited mainly to the western world. We aimed to estimate the prevalence of IBD-related disability and evaluate the associated risk factors in Saudi Arabia. Methods: In this cross sectional study conducted at a tertiary referral center for IBD, the English IBD disk was translated into Arabic, and patients with IBD were approached to complete it. Total IBD disk score (0 = no disability; 100 = severe disability) was documented and a score of >40 was set as a threshold to estimate the prevalence of disability. Results: Eighty patients with a mean age of 32.5 ± 11.9 years and disease duration of 6 years, including 57% females, were analyzed. The mean IBD-disk total score was 20.70 ± 18.69. The mean subscores for each function within the disk ranged from 0.38 ± 1.69 for sexual functions to 3.61 ± 3.29 for energy. The overall prevalence of IBD-related disability was 19% (15/80 scoring >40) and was much higher in active disease, in males and in IBD of long duration (39%, 24%, and 26%, respectively). A clinically active disease, high CRP, and high calprotectin were strongly associated with higher disk scores. Conclusion: Although the overall mean IBD disk score was low, nearly 19% of our population had high scores signifying a high prevalence of disability. As demonstrated by other studies, active disease and high biomarkers were significantly associated with higher IBD-disk scores.

An Unusual Case of Isolated Duodenal Varices With Superior Mesenteric Vein Thrombosis.

Duodenal varices usually occur due to portal hypertension and are rare causes of gastrointestinal tract bleeding. We report a unique case of a previously fit patient who presented with melena and was found to have isolated duodenal varices (DV) in the third part on esophagogastroduodenoscopy. No esophageal or gastric varices were noticed. The duodenal varices were successfully managed by endoscopic banding. A computerized tomography scan of the abdomen to further investigate the cause confirmed duodenal varices and revealed superior mesenteric vein thrombosis. The liver was normal with patent hepatic and portal veins. No evidence of thrombophilia was found. Apixaban was prescribed for superior mesenteric vein thrombosis and on follow-up. no further bleeding was reported.

An Unusual Case of Choledochoduodenal Fistula Secondary to Peptic Ulcer Presenting With Cholangitis and Pneumobilia.

Choledochodoudenal fistula is an uncommon bilio-enteric fistula with clinical presentation ranging from having no symptoms to frank cholangitis. The causes of choledochodoudenal fistula are multiple, with bile duct stones being the most common. Duodenal ulcer is rarely the source of choledochodoudenal fistula. Clinical diagnosis defies acumen, and high-quality imaging including endoscopic or radiologic imaging is required for confirmation. Management of choledochodoudenal fistula is not standardized and remains challenging. We report an unusual case of a choledochodoudenal fistula caused by a duodenal ulcer that presented with pneumobilia and cholangitis. Treatment demanded medical, endoscopic, radiologic, and, ultimately, surgical intervention.

Retrospective Analysis of Characteristics, Indications and Outcomes of Endoscopic Retrograde Cholangiopancreatography (ERCP) in a Tertiary Referral Center in Saudi Arabia.

BACKGROUND:  Endoscopic retrograde cholangiopancreatography (ERCP) is an advanced endoscopic procedure that is an essential tool in the management of pancreaticobiliary diseases. There is limited data available on the indications and outcomes of ERCP from this region. Therefore, we aim to report the characteristics of patients, indications and outcomes of ERCP in Saudi Arabia.  Methods: We retrospectively looked at ERCP procedures done at a tertiary referral center covering the western region of Saudi Arabia from August 2018 until July 2020. Data were collected from the hospital's electronic patient record and endoscopy database. RESULTS:  Of 1001 ERCPs performed, full data was available on 712 procedures on 581 patients that were included in the final analysis. Mean age was 53.1 years. Four hundred four (56.7%) were female. Board-certified consultants performed all ERCPs. The most common intervention was sphincterotomy, which was performed in 563 (96.9%) patients who underwent first-ever ERCP, followed by dilatation and stenting. The commonest indication of ERCP was confirmed or suspected choledocholithiasis (52.6%), followed by replacement or removal of a biliary stent (15.7%), 55 (7.7%) for suspected ascending cholangitis, 54 (7.5%) for acute biliary pancreatitis and 15 (2%) for suspected sphincter of Oddi dysfunction. The commonest finding among all patients was choledocholithiasis in 57.9%, debris in 15.2% and biliary stricture in 14.8%. The commonest complication was pancreatitis in 22 (3.1%) followed by post-sphincterotomy bleeding in 16 (2.2%) and perforation in nine (1.2%). Bleeding was controlled by endoscopic intervention in four (25%) and one (6.2%) patient underwent surgery. One (0.14%) patient had procedure-related mortality secondary to post-procedure pulmonary embolism and one had significant morbidity and prolonged hospitalization because of complicated perforation. The deeper common bile duct (CBD) cannulation rate was 97.3%. CONCLUSION: Our study results revealed that ERCP performed in the western region of Saudi Arabia has similar indications and findings as reported in the international literature. ERCP is successful in achieving the therapeutic objectives with complication rates consistent with published data.

Cytomegalovirus Colitis in a Patient With Ulcerative Colitis on Vedolizumab Monotherapy.

Cytomegalovirus (CMV) is a human herpes-type virus with variable clinical manifestations. Infections in immunocompetent patients are usually asymptomatic or mild, and severe infections are generally seen in immunosuppressed individuals. CMV colitis is not uncommon in patients with ulcerative colitis (UC) and is mostly associated with the use of steroids, immunomodulators like azathioprine, and biologics like infliximab, which have systemic immunosuppressive effects. Vedolizumab is an anti-integrin antibody that is gut-selective without any systemic effects. We report an unusual presentation of a female patient with UC who had concomitant CMV colitis and erythema nodosum, who was on vedolizumab, and not on any steroids or other immunosuppressants. She responded well to anti-viral treatment and steroids.

Self-Expanding Metallic Stents for Palliation of Esophageal Cancer: A Single Center Experience From Saudi Arabia.

BACKGROUND: Self-expanding metallic stents (SEMSs) are increasingly used as a non-surgical alternative for the palliation of advanced esophageal cancer (EC). However, there is a scarcity of real-life experience with the use of these stents exclusively in EC. The aim of this study is to evaluate the efficacy of SEMS in inoperable ECs in the western region of Saudi Arabia. METHODS: A retrospective review of SEMS placed in a tertiary referral hospital for histologically proven inoperable EC from 2016 to 2019. Demographics data, procedure success, complication, re-intervention, and mortality were analyzed. RESULTS: Forty-eight SEMS placed in 35 patients for palliation of dysphagia. The median age of patients was 68 years (range 31-95). 69% (24) patients have a lower third of EC and the rest have a middle third. SEMSs were placed successfully in all cases with symptomatic improvement. No major stent-related complication was seen. 28% (13) patients required re-intervention with additional SEMS placement, nine of which were for tissue in growth and four for distal migration. Median survival was 114 days (range 30-498). Most of the complications seen in fully covered SEMS compared to the partially covered 50% (8/16) vs 17% (5/30), respectively, p = 0.04. Chemo and/or radiotherapy were given to 51% (18) of the patients without any significant benefit on survival (p = 0.79) or re-intervention rate (p = 0.47) compared to those who did not. CONCLUSION: SEMS is effective in palliating dysphagia in inoperable EC without major complications. Rates of tumors in growth and migration were comparable to other studies. SEMS provides long-term palliation.

Randomized trial comparing general anesthesia with anesthesiologist-administered deep sedation for ERCP in average-risk patients.

BACKGROUND AND AIMS: General anesthesia (GA) or monitored anesthesia care (MAC) is increasingly used to perform ERCP. The definitive choice between the 2 sedative types remains to be established. This study compared outcomes of GA with MAC in ERCP performed in patients at average risk for sedation-related adverse events (SRAEs). METHODS: At a tertiary referral center, patients with American Society of Anesthesiologists (ASA) class ≤III were randomly assigned to undergo ERCP with MAC or GA. The main outcome was a composite of hypotension, arrhythmia, hypoxia, hypercapnia, apnea, and procedural interruption or termination defined as SRAEs. In addition, ERCP procedural time, success, adverse events, and endoscopist and patient satisfaction were compared. RESULTS: Of 204 randomized, 203 patients were evaluated for SRAEs (MAC, n = 96; GA, n = 107). SRAEs developed in 35% of the MAC cohort (34/96) versus 9% in the GA cohort (10/107), which was statistically significant (P < .001). Mean induction time for GA was significantly longer than that for MAC (10.3 ± 10 minutes vs 6.5 ± 10.8 minutes, respectively; P < .001). ERCP procedure time, recovery time, cannulation time and success, and procedure-related adverse events were not statistically different between the 2 sedative groups. The use of GA improved endoscopist and patient satisfaction (P < .001). CONCLUSION: GA is safe with fewer SRAEs than MAC in patients with ASA scores ≤III undergoing ERCP. Apart from prolonging induction time, use of GA does not change the procedural success or ERCP-related adverse events and offers greater endoscopist and patient satisfaction. Hence, GA is a consideration in patients undergoing ERCP in this population group. (Clinical trial registration number: NCT04099693.).

Infliximab-Associated Xanthogranulomatous Pyelonephritis: A Rare Complication.

Xanthogranulomatous pyelonephritis (XGP) is one of the rare diseases characterized by chronic inflammation and destruction of the renal parenchyma, and it is usually associated with renal infection, and nephrolithiasis. Infliximab is an anti-tumor necrosis factor-alpha (anti-TNF-α) monoclonal antibody, which is widely used for treating inflammatory bowel disease, and it is known to increase the risk of rare and opportunistic infections. In this study, we report a case of XGP presenting after the initiation of infliximab treatment. We highlight one of the possible complications associated with immunosuppression due to infliximab. Furthermore, the importance of increasing the awareness among physicians for early recognition of this rare complication.

Pilot randomized crossover study comparing the efficacy of transnasal disposable endosheath with standard endoscopy to detect Barrett's esophagus.

BACKGROUND AND STUDY AIMS: The transnasal endosheath endoscope is a new disposable technology with potential applicability to the primary care setting. The aim of this study was to evaluate the efficacy of transnasal endosheath endoscopy (TEE) for the detection of Barrett's esophagus, by comparing the diagnostic accuracy of TEE with that of standard endoscopy. PATIENTS AND METHODS: This was a prospective, randomized, crossover study performed in a single tertiary referral center. Consecutive patients undergoing surveillance for Barrett's esophagus or referred for diagnostic assessment were recruited. All patients were randomized to undergo TEE followed by standard endoscopy or the reverse. Endoscopy experiences and patient preferences were evaluated using a questionnaire. Endoscopic and histologic diagnosis of Barrett's esophagus, and optical image quality of both endoscopic procedures, were compared. RESULTS: A total of 21 of 25 patients completed the study. TEE had sensitivity and specificity of 100 % for an endoscopic diagnosis of Barrett's esophagus, and of 66.7 % and 100 %, respectively, for the histologic diagnosis of Barrett's esophagus. The mean optical quality of standard endoscopy was significantly better than that of TEE (7.11 ±â€Š0.42 vs. 4.06 ±â€Š0.27; P < 0.0001). However, following endoscopy, patients reported a significantly better experience with TEE compared with standard endoscopy (7.05 ±â€Š0.49 vs. 4.35 ±â€Š0.53; P = 0.0006), with 60 % preferring TEE and 25 % preferring sedated standard endoscopy. CONCLUSIONS: In this study, TEE had equal accuracy for an endoscopic diagnosis of Barrett's esophagus compared with standard endoscopy, at the expense of reduced image quality and a lower yield of intestinal metaplasia on biopsy. TEE was better tolerated and preferred by patients. Hence, TEE needs further evaluation in primary care as an initial diagnostic tool.
