High-dose barium impaction therapy for the recurrence of colonic diverticular bleeding: a randomized controlled trial.

OBJECTIVE: We compared the clinical efficacy of barium therapy and conservative therapy in preventing recurrence in patients with diverticular bleeding. BACKGROUND: Previous case reports have indicated that barium impaction therapy provides initial hemostasis for diverticular bleeding and prevention against rebleeding. METHODS: After spontaneous cessation of bleeding, patients were randomly assigned to conservative treatment (n = 27) or high-dose barium impaction therapy (n = 27). Patients were followed up for 1 year after enrollment of the last patient. The main outcome measure was rebleeding. RESULTS: Median follow-up period was 584.5 days. The probability of rebleeding at 30-day, 180-day, 1-year, and 2-year follow-up in all patients was 3.7%, 14.8%, 28.4%, and 32.7%, respectively. By group, probability at 1 year was 42.5% in the conservative group and 14.8% in the barium group (log-rank test, P = 0.04). After adjustment for a history of hypertension, the hazard ratio of rebleeding in the barium group was 0.34 (95% confidence interval, 0.12-0.98). No complications or laboratory abnormalities due to barium therapy were observed. Compared with the conservative group, the barium group had significantly (P < 0.05) fewer hospitalizations per patient (1.7 vs 1.2), units of blood transfused (1.9 vs 0.7), colonoscopies (1.4 times vs 1.1 times), and hospital stay days (15 days vs 11 days) during the follow-up period. No patients died and none required angiographic or surgical procedures in either group. CONCLUSIONS: High-dose barium impaction therapy was effective in the long-term prevention of recurrent bleeding, and reduced the frequency of rehospitalization and need for blood transfusion and colonoscopic examination.

A therapeutic barium enema is a practical option to control bleeding from the appendix.

BACKGROUND: Acute lower gastrointestinal hemorrhage originating from the appendix is rare and often intractable, because it is almost impossible to approach the bleeding point by endoscopy. We herein describe the first case of bleeding from the appendix, which was successively controlled by a therapeutic barium enema administered into the appendix. CASE PRESENTATION: A 71-year-old male visited our hospital because of melena. He has been receiving an anti-coagulation drug, ticlopidine hydrochloride, for 10 years. By an emergency colonoscopy, a hemorrhage was detected in the appendix, and the lesion responsible for the bleeding was regarded to exist in the appendix. Two hundred milliliters of 50 W/V% barium was sprayed into the orifice of the appendix using a spraying tube. The bleeding could thus be immediately stopped, and a radiological examination revealed the accumulation of barium at the cecum and the orifice of the appendix. The barium accumulation disappeared by the next day, and no obvious anal bleeding was observed. Two weeks after stopping the bleeding from the appendix, an appendectomy was performed to prevent any further refractory hemorrhaging. The patient has had no complaints of any abdominal symptoms or anal bleeding for 10 months. CONCLUSIONS: A therapeutic barium enema is a useful procedure to control bleeding from the appendix and to avoid emergency surgery, such as partial cecectomy and hemicolectomy.

Clinical efficacy of various root canal obturating methods in primary teeth: a comparative study.

AIM: The purpose of this in vivo study was to evaluate and compare the efficacy of different obturating methods used in primary teeth, when obturated using a combination of zinc oxide and iodoform paste (Endoflas F.S.). MATERIALS AND METHODS: A group of 29 patients aged 3-9 years and a total of 64 teeth were selected. These 64 teeth (32 anterior teeth=32 canals, and 32 posterior teeth=80 canals) were randomly divided into 4 groups. Teeth were obturated with Lentulo spiral, pressure syringe, bi-directional spiral and Pastinject. Post-operative evaluation was done for: quality of canal obturation, (underfilled, optimally filled, overfilled) and presence of voids. RESULTS: Pastinject exhibited the highest number of optimally filled canals, while the highest number of underfilled canals were observed with bi-directional spiral, and the highest number of overfilled canals were observed with pressure syringe. A minimum number of voids was present in canals filled with the Pastinject technique and pressure syringe. CONCLUSION: These results suggest that Pastinject was the most effective technique for obturation of primary teeth.

Intussusception in children: experience with 105 patients in a department of paediatric surgery, Turkey.

AIM: The aim of this study was to present our experience in patients with intussusception (IN). MATERIALS AND METHODS: One hundred and five cases of IN treated between 1991 and 2007 were analysed. Age, gender, symptoms, signs, diagnostic and treatment methods, types of IN including leading point, and postoperative complications were evaluated. RESULTS: The mean age of the patients was 2.5 years (range 1 month - 15 years). Fifty-nine per cent (62/105) were under 1 year of age, and of these 28% were receiving therapy for upper respiratory tract infection. The most common symptom was colicky abdominal pain. Rectal bleeding was present in all patients under 2 years of age. In 23 children (21.9%) leading points were detected. Thirty per cent of the patients were older than 4 years, and 76.6% of these had leading points. Ultrasonography demonstrated the invaginated segment in 93 patients. Hydrostatic reduction was attempted in 71.4% (75) of the patients and was successful in 48% (36), 70% of whom were under 1 year of age. Of the patients with unsuccessful hydrostatic reduction, 11 required intestinal resection and primary anastomosis and 35 manual reduction. Twenty-four patients were diagnosed by means of ultrasonography and were operated on immediately. Ten of these patients had signs of peritonitis on admission and were treated by resection-primary anastomosis. CONCLUSION: In patients with IN under 2 years of age, hydrostatic or pneumatic reduction may be successful. Considering the high incidence of leading points in older children, one should not persist with reduction but should rather design a treatment plan accordingly, i.e. laparotomy with manual reduction or resection.

An Unusual Presentation of Intussusception.

This is the case of a 9-month-old female infant who presented to the emergency department with a history of several episodes of nonbilious and nonbloody emesis. The patient was found to be afebrile with normal vital signs and an otherwise normal physical examination. Initial plain film radiography was concern for possible obstruction. Imaging studies with ultrasonogram demonstrated intussusception. This was an unusual case of intussusception because children are typically more ill-appearing with vomiting, diarrhea, fevers, lethargy, and blood in stool. Management options included surgery, pneumatic enema reduction, and barium enema reduction. Pneumatic enema reduction was performed. This procedure has been shown to have superior outcomes in infants with intussusception. Advanced practice providers need to provide a detailed history, complete a thorough physical examination, order the appropriate diagnostics, and be vigilant of the clinical manifestation of intussusception.

Clinical and radiographic evaluation of pulpectomies using three root canal filling materials: an in-vivo study.

Various root canal filling materials are used to preserve a pulpally involved carious primary tooth. But there is no single material so far available to fulfill all the requirements of an ideal root canal filling material for a primary tooth. Hence this study was undertaken to evaluate clinically and radiographically the efficacy of three obturating materials - Calcium hydroxide with Iodoform (METAPEX), Zinc Oxide Eugenol with Iodoform (RC FILL) and Zinc Oxide Eugenol and Calcium hydroxide with Iodoform (ENDOFLAS) for a period of 9 months. Results show ENDOFLAS gave an overall success rate of 95.1%, METAPEX - 90.5% and RC FILL - 84.7%. In our study, we conclude that ENDOFLAS, a mixture of Zinc Oxide Eugenol and Calcium hydroxide with Iodoform fulfills most of the required properties of an ideal root canal filling for primary teeth.

Zinc oxide eugenol and Endoflas pulpectomy in primary molars: 24-month clinical and radiographic evaluation.

CONTEXT: Despite modern advancement in material and technical aspect, management of infected primary molars is of prime concern in pediatric endodontics. An effective root canal material plays the major role in achieving the fluid impervious seal by defending against variant microflora and maintaining the tooth in function for longer duration. AIMS: This study aims to evaluate and compare the success of endoflas as root canal filling material in infected primary molars with zinc oxide eugenol (ZOE). MATERIALS AND METHODS: Primary molars with necrotic pulp in healthy, cooperative children were selected. Ethical clearance and informed consent was obtained. Standardized pulpectomy procedure was done and root canals were filled with either ZOE or endoflas. Further follow-up with clinical and radiographic evaluation was carried at 0, 3, 6, 12, and 24 months. The findings obtained were statistically analyzed using Chi-square test. RESULTS: Endoflas showed acceptable results as root canal filling material in primary molars even at 2-year follow-up, though overfilling of root canals led to low success rate compared to teeth with combined optimal and under fillings. There was no significant difference between the two materials (P > 0.05). CONCLUSIONS: Endoflas could be a potential alternative to ZOE for preserving infected primary molars.

A comparative assessment of different techniques for obturation with endoflas in primary molars: An In vivo Study.

PURPOSE: The rationale of this in vivo study was to evaluate and compare different obturation techniques for the intracanal conveyance of Endoflas in the primary molars using conventional radiography. MATERIALS AND METHODS: Thirty-eight children (4-9 years old) with total of 45 pulpally infected primary mandibular molars indicated for pulpectomy were categorized into three groups (i) endodontic pluggers, (ii) lentulospirals, and (iii) NaviTips, respectively, for obturation with Endoflas. The level of obturation and the presence of voids were evaluated radiographically, and the obtained data were statistically analyzed using Chi-square test. RESULTS: The results showed no significant difference between the three techniques to deliver Endoflas. Motor-driven lentulospirals showed better results (64.4% optimal fillings) compared to the pluggers (62.2%), but NaviTips showed poor results (48.9%) for the level of obturation (P > 0.05). Voids were observed in all the techniques used. Pluggers and lentulospirals showed similar results with greater void-free canals, whereas NaviTip system showed more voids which was statistically not significant (P > 0.05). CONCLUSION: Motor-driven lentulospiral and pluggers were almost equally efficient to fill Endoflas to an optimal level, devoid of voids, and both were considered better compared to NaviTip system.

Emergency surgery due to diaphragmatic hernia: case series and review.

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a congenital abnormality, rare in adults with a frequency of 0.17-6%. Diaphragmatic rupture is an infrequent consequence of trauma, occurring in about 5% of severe closed thoraco-abdominal injuries. Clinical presentation ranges from asymptomatic cases to serious respiratory or gastrointestinal symptoms. Diagnosis depends on anamnesis, clinical signs and radiological investigations. METHODS: From May 2013 to June 2016, six cases (four females, two males; mean age 58 years) of diaphragmatic hernia were admitted to our Academic Department of General Surgery with respiratory and abdominal symptoms. Chest X-ray, barium studies and CT scan were performed. RESULTS: Case 1 presented left diaphragmatic hernia containing transverse and descending colon. Case 2 showed left CDH which allowed passage of stomach, spleen and colon. Case 3 and 6 showed stomach in left hemithorax. Case 4 presented left diaphragmatic hernia which allowed passage of the spleen, left lobe of liver and transverse colon. Case 5 had stomach and spleen herniated into the chest. Emergency surgery was always performed. The hernia contents were reduced and defect was closed with primary repair or mesh. In all cases, post-operative courses were uneventful. CONCLUSION: Overlapping abdominal and respiratory symptoms lead to diagnosis of diaphragmatic hernia, in patients with or without an history of trauma. Chest X-ray, CT scan and barium studies should be done to evaluate diaphragmatic defect, size, location and contents. Emergency surgical approach is mandatory reducing morbidity and mortality.

Intussusception: current management in infants and children.

Intussusception remains a leading cause of bowel obstruction in early infancy and childhood. From 1970 to 1985, 83 patients with intussusception were treated. There were 51 boys and 32 girls ranging in age from 2 months to 22 years. Ten patients had a total of 14 separate recurrences; nine occurred during the initial hospitalization. Symptoms on presentation included abdominal pain (80%), palpable mass (60%), rectal bleeding (53%), and lethargy or sepsis (45%). Fifteen children underwent exploration without contrast studies based on duration of symptoms (greater than 5 days) and evidence of severe obstruction on plain abdominal x-ray films. In the remaining children, diagnosis was confirmed by barium enema and hydrostatic reduction was achieved in only 34 patients (42% success rate). Symptoms were present more than 48 hours in 55% of the reduction failures. At operation, five children had spontaneously reduced and an appendectomy was performed. Manual reduction was possible in 32 patients. The intussusception was irreducible in 26 patients, and 18 required temporary stomas. Pathologic lead points were found in 11 patients. Average length of hospitalization was 1.5 days after barium enema reduction, 9.6 days after manual reduction, and 13.8 days after bowel resection. There were no recurrences of intussusception after surgical reduction. A significant morbidity rate was observed with a delay in diagnosis. Adequate preoperative preparation and prompt surgical intervention are associated with 100% survival.

Recurrent intussusception. Risks and features.

OBJECTIVE: To determine the risk factors associated with recurrent intussusception (RI) and to characterize the timing, features, and complications of RI. DESIGN: Retrospective chart review. SETTING: Children's Hospital and Medical Center, Seattle, Wash. PARTICIPANTS: All patients with a diagnosis of intussusception who underwent barium enema as treatment for reduction between October 1, 1979 and December 31, 1990. Children with RI (N = 23, seven with two or more recurrent episodes) were classified as the case group; children with a single intussusception (N = 234), controls. RESULTS: There were no statistically significant differences in age, sex, race, symptoms, duration of symptoms, or results of the physical examination between the case group and controls. Reduction of the initial intussusception by a barium enema occurred in 96% of patients in the case group vs 62% of the controls (odds ratio, 13.50; 95% confidence intervals, 2.10 to 563.4; P = .003). Only one of 33 episodes of RI followed an operative reduction. In comparing the first recurrent episode with the initial episode, there was a significant reduction in the proportion of patients presenting with lethargy (0% vs 30%; Fisher Exact Test, P = .009) or blood in the stool (5% vs 52%; P < .002) and a drop in the median duration of symptoms from 20 to 6 hours. CONCLUSIONS: Recurrent intussusception cannot be predicted by presenting features or symptoms; operative reduction due to a failed reduction by a barium enema reduces the risk of RI; and patients with RI have fewer symptoms with a shorter duration.

Etiologic and therapeutic aspects of intussusception in childhood.

Analysis of fifty-two instances of intussusception proved the importance of barium enema examinations as a diagnostic and therapeutic modality. Hypertrophy of the lymphatic tissue in the terminal ileum reactive to common diseases of infancy and childhood is of utmost importance in the etiology of "idiopathic intussusception."

Radiologic diagnosis of benign esophageal strictures: a pattern approach.

Benign esophageal strictures are a leading cause of dysphagia. Therefore, radiologists have an important role in detecting esophageal strictures and determining their cause. The most common cause of strictures in the distal esophagus is gastroesophageal reflux disease. Reflux-induced ("peptic") strictures may be associated with sacculations, fixed transverse folds, or esophageal intramural pseudodiverticula. In addition, scleroderma, nasogastric intubation, Zollinger-Ellison syndrome, and alkaline reflux esophagitis may be associated with stricture formation in the distal esophagus. Upper and midesophageal strictures may be caused by Barrett esophagus, mediastinal irradiation, ingestion of drugs or caustic substances, congenital esophageal stenosis, skin diseases, or esophageal intramural pseudodiverticulosis. Other unusual causes of esophageal stricture formation include Crohn disease, Candida esophagitis, graft-versus-host disease, eosinophilic esophagitis, Behçet disease, endoscopic sclerotherapy for esophageal varices, and glutaraldehyde contamination at endoscopy. Esophageal strictures are best evaluated with biphasic esophagography that includes both single- and double-contrast spot images. When esophageal strictures are detected at barium examination, the underlying cause can often be determined with a pattern approach that takes into account the clinical history, the appearance and location of the strictures, and the presence of other associated radiographic findings.

Immediate radiographic assessment following laparoscopic antireflux operations is unnecessary.

BACKGROUND: Laparoscopic antireflux operations (LAP) have become increasingly common for the treatment of gastroesophageal reflux disease (GERD). We sought to determine if routine postoperative barium contrast studies following LAP were clinically efficacious in identifying technical problems and life-threatening complications related to the surgical intervention. METHODS: From January 1996 to December 1997, 112 barium studies were performed following 112 LAP procedures (47 male/65 female patients; mean age, 51 years) (group I). This group was compared to a subsequent cohort of 67 patients who underwent LAP between January 1998 and July 1998 without routine early postoperative barium contrast study (group II). RESULTS: In 111/112 of the barium studies of group I, no radiographic abnormality was identified. The average length of stay (LOS) for these patients was 2.6 days. Routine barium studies were not utilized in group II. The average length of stay for patients in group II was 1.4 days. Twelve group II patients underwent early postoperative barium studies to evaluate suspicious clinical symptoms. None of these 12 postoperative studies identified important problems, nor did they alter the patients' clinical management. However, because of the barium study, their LOS was equivalent to those patients who had undergone routine barium study (2.4 days). There was an increase of $1451.80 in hospital charges in the group of patients who had a barium study, largely as a result of the increased LOS. CONCLUSION: The routine use of these studies results in increased patient charges and a prolongation in the length of hospital stay. Immediate postoperative barium studies following laparoscopic antireflux operations are of little value in determining important postoperative problems among patients undergoing LAO.

The management of intussusception.

A scheme of management to achieve maximum success in hydrostatic reduction of intussusception is presented. This takes into account patient selection, radiological technique and the follow-up clinical assessment. By standardizing the management we have increased our success rate and avoided laparotomy in 64% of our patients. Most of the patients in whom the technique failed had infarcted bowel which required resection.

Variations in the radiological management of intussusception: results of a postal survey.

A survey of the radiological reduction of intussusception in a selection of British hospitals was performed using a questionnaire. Replies were received from radiologists working in 51 district general hospitals and 25 teaching hospitals or specialist paediatric institutions. Most district general hospitals still use barium as the sole method of reduction of intussusception. Most teaching hospitals and specialist paediatric units have changed to a pneumatic method. The contra-indications, details of patient preparation and technical details of each method varied considerably.

[Catheter embolisation of renal tumours (author's transl)]. / Katheterembolisation von Nierentumoren

Arterial embolisation of renal tumours with foreign particles is described. This involves occlusion of the arteries supplying the tumour through a catheter introduced by the trans-femoral route. Pre-operative and therapeutic embolisation should be distinguished. During pre-operative embolisation, the kidney should be totally occluded by the foreign particles in order to obtain a bloodless operation zone and in order to avoid the much feared production of tumour emboli. Because of the clinical consequences of renal artery emboli, this procedure should be carried out immediately before the operation. During therapeutic embolisation, which is not followed by an operation, only those vessels supplying the tumour should be occluded in order to avoid the complications of a renal embolus. Ischemia of the tumour and less rapid growth may then be excluded.

Intussusception: barium or air?

At The Hospital For Sick Children, the use of air has recently replaced the use of barium in the reduction of intussusceptions. The purpose of this study was to review the results from 200 consecutive patients with intussusceptions, 100 patients treated with barium enema and 100 patients treated with air enema. The groups were similar with regard to sex, average and median ages, and presenting symptoms and signs. Successful reduction was achieved in 75% of episodes of intussusception treated with barium enema and 76% treated with air enema. Failure of either modality showed a high association with the presence of either a lead point or an ileoileal or ileoileocolic intussusception. Among those cases of unsuccessful reduction, operation was performed in all 59 cases; resection in 30 cases, manual reduction in 19, and spontaneous reduction was found in 10. There were three perforations during attempted reduction with barium and two with air. All perforations were treated by resection and primary anastomosis. There were 18 recurrent intussusceptions following barium enema reduction and nine following air enema reduction. Therefore, with the lower absorption of x-rays by air and the relatively inert nature of air (compared with barium in the event of a perforation), we feel that air enema is the treatment of choice in the initial management of intussusception.

Colon perforation during attempted barium enema reduction of intussusception.

In reviewing the records of almost 1000 infants and children with intussusception in two children's hospitals over the last 25 yr, there have been seven bowel perforations during attempted hydrostatic barium enema reduction of an intussusception. Except for one instance, these have all occurred during the last 6 yr. The infants were all 6 mo old or less and most had a preceeding viral illness. Only 4 of the 7 had pain, all vomited, in only 2 was a mass felt and all but 1 had rectal bleeding. The duration of these signs and symptoms was longer than 36 hr with most ill for 3 or 4 days. All seven infants had abdominal x-rays that showed complete small bowel obstruction. Once the intussusception was suspected, barium enema reduction was attempted without excessive hydrostatic pressure and not for a prolonged time; all the ileocolic intussusceptions were met in the transverse colon with only a minimal reduction produced. It was at this time that a perforation was suddenly noted. All infants required immediate right hemicolectomy for the area (s) of colonic necrosis. Postoperatively, there were two wound infections, a volvulus which left the child with a short gut and another infant suffered severe brain damage. These babies seem to fit a pattern in which they are younger and sicker longer than the average infant with an intussusception, and have a complete small bowel obstruction. These facts may be a warning that such infants are at increased risk for a barium enema bowel perforation.
