Patient Attendance and Outcomes in a Structured Weight Management Program.

OBJECTIVES: To determine service utilization and identify patient characteristics associated with service utilization in youth with obesity presenting for structured weight management, and to explore weight-related outcomes associated with service utilization. STUDY DESIGN: In this retrospective study conducted between January 2008 and December 2013, we examined variables associated with the care of 2089 patients aged 2-18 years presenting for an initial visit to 2 tertiary care-based, multidisciplinary structured weight management clinics. RESULTS: Only 53% of patients returned for a second visit, 29% returned for a third visit, and virtually none (0.5%) completed the recommended 6 visits within 6 months. Patients who were Hispanic, government-insured, and whose parent/s spoke Spanish were more likely to return to clinic. Of those patients who returned for at least a second visit, 70% demonstrated a reduction in or maintenance of body mass index z-score. CONCLUSIONS: Patient retention remains a significant barrier to effective pediatric weight management. Structured weight management programs should increase their efforts to engage patients and families at the initial visit and identify and address barriers to follow up.

An effective pyloromyotomy length in infants undergoing laparoscopic pyloromyotomy.

BACKGROUND: Traditional management of pyloric stenosis has consisted of open pyloromyotomy during which the surgeon is able to palpate and determine whether the hypertrophied pylorus has been completely divided. During the last decade, laparoscopic pyloromyotomy has become an increasingly popular approach for this condition. The purpose of this study was to determine whether there is an effective pyloromyotomy length that will allow the surgeon to feel confident that a complete pyloromyotomy was performed with the laparoscopic approach. METHODS: All infants undergoing laparoscopic pyloromyotomy from October 1999 through October 2003 at a single institution were retrospectively studied. Clinical variables collected included the patient's age, gender, electrolyte status on admission, the elapsed time from admission to operation, ultrasonographic dimensions of the hypertrophied pylorus, operative time, the length of the pyloromyotomy performed, the time to initial and to full feedings, and the duration of the postoperative hospitalization. RESULTS: One hundred seventy-one patients comprised the study group. The age (mean +/- standard deviation) at the time of operation was 5.2 +/- 2.8 weeks. The mean preoperative ultrasonic measurements for both pyloric thickness and pyloric length were 4.3 +/- 0.7 mm and 19.5 +/- 2.8 mm, respectively. The average pyloromyotomy incision length for this entire group was 1.9 +/- 0.21 cm. The mean operative time was 23.5 +/- 8.3 minutes. There were no mucosal perforations, no conversions to an open procedure, and no evidence for an incomplete pyloromyotomy. CONCLUSIONS: Laparoscopic pyloromyotomy is a safe and effective technique for infants with pyloric stenosis. A pyloromyotomy incision length of approximately 2 cm appears to be an effective measure of a complete pyloromyotomy.
