Crohn's disease in a Saudi outpatient population: is it still rare?

BACKGROUND/AIM: To determine the epidemiology of Crohn's disease (CD) in an outpatient clinic and compare it with data previously reported from different centers in the Kingdom of Saudi Arabia and outside. MATERIALS AND METHODS: The medical records of all patients with CD seen in the clinic in the period from January 1993 through December 2007 were reviewed. The demographic, clinical data and methods of diagnosis were retrieved. RESULTS: Over a period of 15 years, we saw 133 Saudi patients with CD. They were predominantly young, with a median age of 26.2 years and male preponderance (2.3:1). The final diagnosis was established within 1 week of presentation in 47% of the patients. The leading symptoms were abdominal pain (88%), diarrhea (70%), bloating (61%), rectal bleeding (50%), weight loss (33%), constipation (24%) and perianal disease (23%). The diagnosis was established by endoscopy and histopathology. Ileocecal involvement was encountered in 40% of the patients. CONCLUSION: From the current study, it is obviously possible to diagnose a large proportion of patients with CD in a gastroenterology outpatient clinic. The data revealed a strikingly increased incidence of CD in a mainly young Saudi population in the past few years.

Gastrointestinal tract bleeding in intellectually disabled adults.

BACKGROUND: Gastrointestinal (GI) tract bleeding in intellectually disabled (ID) individuals presents peculiar diagnostic and management difficulties. This study details the experience of a tertiary referral teaching hospital in Central Saudi Arabia in the management of GI bleeding necessitating admission in ID adults. PATIENTS AND METHODS: Prospective collection of data was taken on consecutive ID adults admitted for GI bleeding from January 2000 through December 2004. Demographic details, clinical presentation, diagnosis, associated physical and neurologic disabilities, etiology of bleeding and treatment outcome were analyzed. RESULTS: Thirty-nine ID adults accounted for 44 admissions during the period under review. Twenty-six (66.7%) patients were admitted with upper, and 13 (33.3%) for lower GI bleeding. Reflux esophagitis (57.7%) remained the most common cause of upper GI bleeding. Five out of 26 patients with upper and 6 of 13 with lower GI bleeding needed operative treatment. Various congenital anomalies or malformations were observed frequently associated with lower GI bleeding. CONCLUSIONS: Bleeding GERD remained the most common etiology of upper GI bleeding necessitating admission. Endoscopy is the mainstay in diagnosis and initial management of ID patients. Continued surveillance endoscopy is recommended for early diagnosis of Barrett changes. Bleeding from developmental malformations may have association with intellectual disability.

Mirizzi syndrome: ten years experience from a teaching hospital in Riyadh.

OBJECTIVE: Mirizzi syndrome (MS) is an uncommon presentation of cholelithiasis. This study aims to find the incidence and analyze the outcome of management of this condition at Riyadh Medical Complex (RMC) with particular reference to diagnostic methods and outcome of surgical treatment. METHODS: Retrospective study on 17 consecutive patients of MS diagnosed and managed at RMC over ten year period. The records were reviewed for demography, clinical presentation, diagnostic methods, operative procedures, postoperative complication and follow up. RESULTS: The incidence of MS syndrome was 0.7% of 2415 cholecystectomies. There was preponderance of Type I variety (58.8%). Ultrasonography was able to diagnose 82% cases. ERCP suggested the diagnosis in all cases and helped further in classifying and management of these patients. All Type I cases were managed with partial cholecystectomy, two underwent laparoscopic surgery. Three Type II patients were managed by partial cholecystectomy alone. Three patients with Type III variety had choledochoplasty whereas one remaining patient with Type IV variety underwent hepatico-jejunostomy. All patients had complete recovery with 17.6% procedure-related morbidity and no hospital mortality. All patients are doing well over a mean follow up 6.5 years. CONCLUSION: Preoperative diagnosis of Mirizzi syndrome by ultrasound and ERCP is essential to prevent serious complications during surgery. Partial cholecystectomy is an adequate procedure for Types I & II MS. Choledochoplasty provides an effective surgical repair in Type III cases. Although laparoscopic cholecystectomy in MS may be hazardous, it may still be tried in preoperatively diagnosed type I cases, provided the surgeon is experienced and keeps a low threshold for conversion open surgery.

Granular cell tumour of the ampulla of Vater.

Granular cell tumour (GCT) is a rare soft tissue neoplasm commonly encountered in the head and neck region, skin and subcutaneous tissue. GCT of the biliary system is most commonly reported in African-American females and usually presents as abdominal pain and obstructive jaundice. The neoplasm constitutes less than 10% of all benign tumours of the extra-hepatic biliary tree. No case of GCT involving the ampulla of Vater has been reported in the literature to date. We report a case of benign GCT involving the ampullary region in a 44-year-old Ethiopian male. Preoperative diagnosis was available on ERCP and deep biopsy. The patient was managed by debulking resection and biliary-enteric bypass and is symptom-free with no evidence of tumour progression after a follow-up of one year.

Initial factors predicting rebleeding and death in bleeding peptic ulcer disease.

OBJECTIVE: Bleeding peptic ulcer constitutes approximately half of the cases admitted with upper gastrointestinal bleeding. Although the bleeding episode stops spontaneously in most of them, rebleeding occurs in as much as 10-30% of them and has a mortality rate of 5-10%. In this study, we have evaluated the possible significant predictors associated with this adverse outcome. METHODS: The records of 205 patients admitted to gastrointestinal bleeding unit (GIBU) in Riyadh Central Hospital, during the period May 1996 through to April 1999, with endoscopic confirmed diagnosis of bleeding peptic ulcer disease were reviewed for demography, clinical presentation, hematology, biochemistry, initial blood pressure, nasogastric lavage color, co-morbid disease and endoscopic findings. All the significant factors found initially (P<0.05) were entered into odds ratio and its 95% confidence interval and finally the unconditioned logistic regression model was used to find out the significant independent predictors for both rebleeding and mortality in these patients. RESULTS: The majority of patients (85%) were males and below the age of 60 (73%). Duodenal ulcer was the source of bleeding in 84%. Endoscopy was performed in all patients within 24 hours of admission. Only 15% were actively bleeding at the time of initial endoscopy. Thirty-six patients (17%) rebelled, majority within 72 hours of initial hemostasis. Overall, 11 patients (5%) died, 6 of them were rebleeders. Initial presentation of systolic blood pressure <100 mm Hg, blood in nasogastric tube and visible vessel within the ulcer in endoscopy were independent predictors of rebleeding while initial systolic blood pressure <100 mm Hg and age >60-years were independent predictors of mortality. CONCLUSION: Improvement of outcome in patients with bleeding peptic ulcer disease can be achieved by early detection of those patients who are at risk of adverse outcome. Patients with the above mentioned independent predictors of rebleeding and mortality are best managed in the intensive care unit with endoscopic hemostasis and proton pump inhibitor (PPI) therapy for a minimum of 5-days of admission.
