long terms results of draf type iii modified endoscopic lothrop frontal sinus Drainage Procedure in 122 patients a single centre experience
Rhinology, 2011Co-Authors: Christos Georgalas, F S Hansen, W J M Videler, W J FokkensAbstract:OBJECTIVES To assess the effectiveness and factors associated with restenosis after Draf type III (Endoscopic Modified Lothrop) frontal sinus Drainage Procedure. DESIGN Retrospective analysis of prospectively collected data. PATIENTS A hundred and twenty two consecutive patients undergoing Draf III Procedure for recalcitrant chronic frontal rhinosinusitis (CRS) (71%), frontal sinus mucocoele (15%), benign frontal sinus tumours (9%) and cystic fibrosis with severe CRS (5%) were followed up for an average of 33 months. OUTCOME MEASURES Symptom burden (Visual Analogue Scale and Rhinosinusitis Outcome Measure), patency of neo-ostium and revision surgery. RESULTS At the end of follow up, ninety percent of patients had a patent neo-ostium, while 88% were either clinically better or completely asymptomatic. Thirty-nine patients required endoscopic revision surgery and 9 eventually underwent frontal sinus obliteration. Sixty percent of revision operations were performed during the first two years. RSOM showed a significant improvement in both general and nasal symptoms while on a VAS, headache improved significantly. The only factor weakly associated with re-stenosis was the presence of allergy. There were no major complications during any of the Procedures. CONCLUSION Draf III Procedure is safe and effective for patients who have failed conventional frontal sinus Procedures and a valid alternative to frontal sinus obliteration. Although the revision rate may appear to be quite significant, it can often be performed as an outpatient Procedure and needs to be balanced against the reduced morbidity and the ease of follow-up.

causes and rates of 30 day readmissions after percutaneous transhepatic biliary Drainage Procedure
Radiology, 2019Co-Authors: Ammar Sarwar, Christopher A Hostage, Jeffrey L Weinstein, Geunwon Kim, Victor Novack, Nihara Chakrala, Yojin Park, Olga R Brook, Muneeb AhmedAbstract:Purpose To investigate rates and causes of 30-day readmission for patients who undergo percutaneous transhepatic biliary Drainage (PTBD) Procedures. Materials and Methods In this retrospective study, PTBD Procedures performed at a tertiary care institution (June 2008 to May 2013) were reviewed. For each patient, the first 30-day readmission was used to determine cause of readmission. Two interventional radiologists independently categorized causes for readmission as planned or unplanned, and unplanned causes as related to or unrelated to interventional radiology. Interventional radiology-related readmissions were categorized as potentially preventable or unpreventable. Factors associated with higher odds for 30-day readmission were identified with univariable and multivariable analysis. Results There were 266 Procedures in 266 patients (mean age, 67 years; interquartile range, 57-76 years; 53.4% men). The cause of obstruction was malignant in 50.0% of patients (133 of 266). There were 122 of 266 patients (45.9%) readmitted within 30 days. Of these readmissions, 44 of 122 (36.1%) were planned and 78 of 122 (63.9%) were unplanned. A majority of unplanned readmissions (57 of 78; 73%) were related to interventional radiology. Of unplanned interventional radiology-related readmissions, 16% (nine of 57) were related to periprocedural complications and 51% (29 of 57) were considered preventable. At multivariable analysis, Medicaid insurance (odds ratio, 3.68; 95% confidence interval: 1.52, 9.99; P = .009) and bilateral PTBDs (odds ratio, 5.81; 95% confidence interval: 1.79, 18.90; P = .003) were associated with 30-day readmission. Conclusion Thirty-day readmissions after primary biliary Drainage are common and a majority of unplanned readmissions are drain-related. Nearly half of unplanned interventional radiology-related readmissions are potentially preventable. © RSNA, 2018 See also the editorial by Nikolic in this issue.

laparoscopic truncal vagotomy and gastroenterostomy for pyloric stenosis
American Journal of Surgery, 1996Co-Authors: Andrew Wyman, Robert C Stuart, S Sydney C ChungAbstract:Background Gastric outlet obstruction secondary to chronic duodenal ulceration is an indication for surgery as conservative management with balloon dilatation frequently fails. The standard operation is truncal vagotomy and a Drainage Procedure. However, development of minimally invasive surgery has revolutionized the surgical approach to this clinical problem. Methods Twelve male patients with pyloric stenosis secondary to duodenal ulceration underwent laparoscopic truncal vagotomy and gastrojejunostomy. The perioperative and long term outcome of this group of patients were analyzed. Results The median operating time was 210 (range 180 to 240) minutes. Median postoperative stay was 6 (range 4 to 41) days. Conversion to laparotomy was necessary in one patient. Delayed gastric emptying occurred in two patients but resolved on conservative measures. At a median postoperative followup of 6 (range 1 to 12) months all patients had a good symptomatic outcome (Visick grades I or II). Conclusions Laparoscopic truncal vagotomy and gastrojejunostomy is a feasible technique. Intermediate followup shows good symptomatic results when used for pyloric stenosis.
