The bleeding from colonic diverticula is the most common cause of acute lower gastrointestinal bleeding. Herein, we report four cases of severe and persistent bleeding of colonic diverticular disease that could be treated with a high concentration barium enema. These four cases showed a similar pattern of bleeding whose source could not be identified. Colonoscopy revealed fresh blood in the entire colon and many diverticula were noted throughout the colon. No active bleeding source was identified, but large adherent clots in some diverticula were noted. After endoscopic and angiographic therapies failed, therapeutic barium enema stopped the severe bleeding. These patients remained free of re-bleeding in the follow-up period (range 17-35 mo) after the therapy. We report the four case series of therapeutic barium enema and reviewed the literature pertinent to this procedure.展开更多

METHODS:...AIM: To investigate the effectiveness and safety of limited endoscopic sphincterotomy (EST) plus large balloon dilation (LBD) for removing choledocholithiasis in patients with periampullary diverticula (PAD). METHODS: A total of 139 patients with common bile duct (CBD) stones were treated with LBD (10-20 mm balloon diameter) after limited EST. Of this total, 73 patients had PAD and 66 patients did not have PAD (controls). The results of stone removal and complications were retrospectively evaluated. RESULTS: There were no significant differences between the PAD and the control groups in overall successful stone removal (94.5% vs 93.9%), stone removal in first session (69.9% vs 81.8%), mechanical lithotripsy (12.3% vs 13.6%), and complications (11.0% vs 7.6%). Clinical outcomes were also similar between the types of PAD, but the rate of stone removal in first session and the number of sessions were significantly lower and more frequent, respectively, in type B PAD (papilla located near the diverticulum) than controls [23/38 (60.5%) vs 54/66 (81.8%), P = 0.021; and 1 (1-2) vs 1 (1-3), P = 0.037, respectively] and the frequency of pancreatitis was significantly higher in type A PAD (papilla located inside or in the margin of the diverticulum) than in controls (16.1% vs 3.0%, P = 0.047). CONCLUSION: Limited EST plus LBD was an effective and safe procedure for removing choledocholithiasis in patients with PAD. However, some types of PAD should be managed with caution.展开更多

METHODS： One hundred and forty patients, treated for symptomatic diverticular disease in a community based hospital, were included. Thirty （21%） had signs of diverticular bleeding. Age, gender, and the results of colonoscopy were collected and compared to a group of patients with nonbleeding symptomatic diverticulosis. Records were reviewed for comorbidities, such as obesity, alcohol consumption, smoking habits and metabolic diseases. Special emphasis was put on arterial hypertension, cardiovascular events, diabetes mellitus, hyperuricemia and hypercholesterinemia. RESULTS： There was no difference between patients with diverticular hemorrhage and those with nonbleeding symptomatic diverticulosis regarding gender ratio （male/female 9/21 vs 47/63） and diverticular Iocalisation. Bleeding patients differed in respect to age （73.4± 9.9 vs 67. 8± 13.0, P 〈 0.013）. Significant differences were found between both groups regarding the presence of hyperuricemia and use of steroids and nonsteroidal anti-inflammatory drugs. Patients with three concomitant metabolic diseases were also identified as being at risk of bleeding. A forward stepwise logistic regression analysis revealed steroids, hyperuricemia and the use of calcium-channel blockers as independent risk factors of bleeding.CONCLUSION： Beside nonsteroidal anti-inflammatory steroid drug use, antihypertensive medication and concomitant arteriosclerotic diseases are risk factors for colonic diverticular hemorrhage. Our results support the hypothesis of an altered arteriosclerotic vessel as the source of bleeding.展开更多

Most of times the diagnosis is carried out in case of related complications, such as diverticulitis, hemorrhage, perforation or obstruction. Intestinal obstruction can be caused by inflammatory stenosis due to repeated episodes of diverticulitis, volvulus, intussusception or jejunal stones. Herein we report a case of multiple jejunal diverticula causing chronic gastrointestinal obstruction.展开更多

The majorities are asymptomatic but they can present with complications. Objective: The objective of this study is to describe the clinical presentations, complications, urographic diagnosis of calyceal diverticulae, megacalycosis, and their treatment. Methods: A descriptive study carried out over 8 years period from March 2012 to December 2019. In three big hospital of Aden province, we collect 15 patients aged from seven to 41 years (mean 13.5 years), our patients were 9 female (60%) and 6 male (40%). They diagnosed incidentally with calyceal diverticulae and megacalycosis by contrasted urography, describing the clinical manifestations, localization, complications, and type of treatment. Results: Sixty percent of patients with calyceal diverticulae and megacalycosis were women and (40%) were men. Clinical manifestations including, dull aching flank and abdominal pain in (40%), acute renal colic (20%), recurrent urinary tract infection (33%), and abdominal pain with a fever of unknown origin in (7%). Calyceal diverticula and megacalycosis were bilateral in (53%) and unilateral in (47%). In the right kidney were (57%), and in the left kidney (43%). In the upper pole of the kidney were (53.3%), middle pole (33.3%), and lower pole (13.3%). Complications occurred in (47%) of patients. They including, urinary stones in (71.4%), hypertension (14.3%), and delayed renal excretion (14.3%). Conservative treatment carried out in (73%) and surgically intervened in (27%). Conclusions: Calyceal diverticula and megacalycosis are rare anomalies. Dull aching flank pain and recurrent urinary tract infections are the most frequent clinical presentations. The most common complications are urinary stones. Conservative treatment is a common type of treatment.展开更多

文摘Lower urinary tract symptoms(LUTS)in women produce significant bother.Common conditions causing LUTS in women include urinary tract infections,overactive bladder,and stress incontinence.Urethral diverticulae and female urethral strictures are rare pathologies.They can cause symptoms,which can mimic commoner conditions,leading to delay in diagnosis and unnecessary delay in treatment.In this article,we discuss in detail the definition,symptoms,epidemiology,pathogenesis,diagnosis,and treatment option for these two conditions.Further understanding of these conditions will aid in the proper diagnosis and prevent delay in management.
