Manometry: technical issues.

Abstract

Manometry involves many technical issues, and a complete understanding of all aspects of the esophageal testing process is required to study the human esophagus in a way that yields accurate, technically sound qualitative and quantitative studies that include the measure of esophageal length and positional plotting of transducers within the esophagus. Topics discussed are catheter measurement and memory; checking the system; performing manometry; patient history; intubation technique; marking, mapping, and measuring the esophagus, and analysis of results.

Catheter-related deep venous thrombosis and other catheter complications in children with cancer.

PURPOSE: Asymptomatic deep vein thrombosis (DVT) is a complication of central venous catheter (CVC) use in children with cancer, but its clinical significance is not well defined. Children with CVCs commonly experience two other CVC-related complications: occlusion and infection. The aim of this study was to determine the frequency of these two complications and their association with DVT. PATIENTS AND METHODS: We conducted a retrospective cohort study of patients who were diagnosed with cancer. Data collected included number and type of catheter insertions, duration of use, reason for removal, associated catheter complications, and demographic information. RESULTS: Catheters were placed in 287 patients for a total of 128,403 days (mean, 290 +/- 269 days/catheter). Of 21 patients (7%) diagnosed with CVC-related DVT, only five had specific signs or symptoms. Nineteen (90%) of these 21 children had prior history of catheter occlusion, and 10 of the 19 also experienced infection. Ten children (48%) were not identified as having DVT until they had had multiple catheters with recurrent complications. Odds of having DVT were higher in patients who had a single catheter complicated by repeated occlusions (odds ratio [OR], 3.7; P = .001) or infection (OR, 2.2; P = .016). Patients experiencing both infection and occlusion were at 6.4 times (P < .0001) higher risk of developing DVT. CONCLUSION: Children with CVC-related DVT frequently have recurrent catheter complications. Unrecognized thrombosis may therefore be clinically important. Prospective studies are needed to determine if identification and treatment of occult DVT will prevent additional CVC-related complications and prolong the duration of catheter use.

Comparison of two endoscopically assisted procedures in primary surgical treatment of congenital nasolacrimal duct obstruction in children older than 3 years: balloon dilatation and bicanalicular silicone tube intubation.

OBJECTIVES: To determine the success of two transnasally endoscopic assisted procedures as balloon dilatation and bicanalicular silicone tube intubation for the primary surgical treatment of congenital nasolacrimal duct obstruction in children older than 3 years. STUDY DESIGN: Prospective randomized clinical trial. METHODS: An interventional case series of consecutive primary endoscopic assisted balloon dilatation (BD) and bicanalicular silicone tube intubation (STI) for congenital nasolacrimal duct obstruction in children older than 3 years was reviewed. BD was performed in 20 eyes of 17 patients and STI was performed 24 eyes of 20 patients. Clinical success was defined as a complete remission of epiphora at the end of follow-up period of 12 months and a continuation of the remission at least for 4 months. RESULTS: Eighteen out of 20 eyes (90%) nasolacrimal ducts responded to BD whereas the rate was 15 out of 24 eyes (62.5%) in STI group. No significant complications occured in BD group while the complication rate in STI group was 8 out of 24 eyes (33.3%). chi(2)-Statistical analysis showed significantly better results for BD in clinical success and complication rates than those of STI. CONCLUSIONS: BD should be the first choice therapy instead of invasive approaches with high rate of complications and lower success rates such as silicone intubation, in patients who are older than 3 years.

Cutting seton for pilonidal disease: a new approach.

I present a technique for dealing with chronic pilonidal disease that avoids use of general anesthesia, long hospital stay, complex wound care and prolonged disability that has so often been associated with more traditional surgical treatment in the past. Satisfactory resection was achieved by means of a single cutting seton (garrotte) in 8 patients, 5 males and 3 females ranging in age from 18 years to 31 years, all of whom had had prior unsuccessful incision and drainage for long-standing disease with local abscesses and suppuration. The seton was applied in an ambulatory care setting under local anesthesia. It was tied and progressively tightened over a period of two weeks. Complete excision of the diseased area was achieved and revascularization of the wounds site occurred with optimum healing by secondary intention, leaving an acceptable scar. It required minimal wound care. There were no recurrences over an average follow-up period of 22.5 months. All patients were uniformly satisfied. The encouraging preliminary results for this novel technique suggest that it is simple, safe and effective. It requires evaluation in a larger series with longer follow-up.
