Top to Bottom: A New Method for Assessing Adequacy of Laparoscopic Pyloromyotomy

Introduction: Hypertrophic pyloric stenosis is a commonly encountered pediatric surgical issue. Initially treated with open surgical techniques, many pediatric surgeons have adopted the minimally invasive approach using laparoscopy. However, some concerns exist that the rate of incomplete pyloromyotomy is elevated in laparoscopy. We propose a new technique to assess the adequacy of laparoscopic pyloromyotomy. Methods: Adequacy of laparoscopic pyloromyotomy was assessed by confirming that the top of the serosa on one side of the pylorus has adequate freedom to reach the bottom of the muscle on other side. A retrospective review of patients undergoing laparoscopic pyloromyotomy confirmed by this method from March 2012 to January 2016 was conducted. Demographics, laboratory values on admission, and postoperative outcomes were collected. Descriptive statistics was utilized. Results: Thirty-three patients were included. Median age was 30 days (interquartile range [IQR]: 24, 47). Median pylorus length and thickness were 19?mm (IQR 17.3, 21) and 4.5?mm (IQR: 4.0, 4.8), respectively. Median time to first full feed was 8.5 hours (IQR: 6.6, 15.6). Twenty-three (69%) patients had postoperative emesis. Median length of stay postoperation was 26.5 hours (IQR: 21.1, 44.7). There were no reoperations for incomplete pyloromyotomy and no infections. On follow-up, 1 patient had prolonged postoperative emesis that resolved without further intervention and 1 patient on peritoneal dialysis before surgery had an incisional hernia that required operation in the setting of bilateral inguinal hernias. Conclusion: In a small series, the top to bottom assessment appears to confirm adequacy of pyloromyotomy.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/140155/1/lap.2016.0303.pd

Improving rigid fiberoptic intubation: a comparison of the Bonfils Intubating Fiberscope™ with a novel modification

<p>Abstract</p> <p>Background</p> <p>The Bonfils intubating fiberscope has a limited upward tip angle of 40° and requires retromolar entry into the hypopharynx. These factors may make its use less desirable when managing the difficult airway because most anesthesia providers are well versed in midline oral intubation rather than the lateral retromolar approach. The <it>Center for Advanced Technology and Telemedicine </it>at the University of Nebraska Medical Center has developed a novel fiberscope with a more anterior 60° curve to allow for easier midline insertion and intubation. The objective of this work was to evaluate the novel fiberscope, in comparison to the Bonfils intubating fiberscope, in terms of use and function in difficult airway intubation.</p> <p>Methods</p> <p>Twenty-two anesthesia providers participated in simulated intubations of a difficult airway mannequin to compare the Bonfils intubating fiberscope with the novel curved Boedeker intubating fiberscope. The intubations were assessed based upon the following variables: recorded Cormack Lehane airway scores, requests for cricoid pressure, time to intubation, number of intubation attempts and success or failure of the procedure.</p> <p>Results</p> <p>Participants using the Bonfils fiberscope recorded an average Cormack Lehane (CL) airway score of 1.67 ± 1.02 (median = 1); with the novel fiberscope, the recorded average airway grade improved to 1.18 ± 0.50 (median = 1). The difference in airway scores was not statistically significant (p = 0.34; Fishers Exact Test comparing CL grades 1&2 vs. 3&4). There was, however, a statistically significant difference in intubation success rates between the two devices. With the Bonfils fiberscope, 68% (15/22) of participants were successful in intubation compared to a 100% success rate in intubation with the novel fiberscope (22/22) (p = 0.008). After the intubation trial, the majority of participants (95%) indicated a preference for the novel fiberscope (n = 20).</p> <p>Conclusions</p> <p>With this data, we can infer that the novel fiberscope curvature appears to improve or maintain the quality of an intubation attempt (airway score, cricoid pressure requirement, intubation time, number of attempts, placement success). The data indicate that the novel fiberscope offers a superior intubation experience to currently available best practices. The instrument was well received and would be welcomed by most study participants should the device become clinically available in the future.</p

Energy efficient window design and technology applicable for residences of the Southwest

Windows are an essential design element of desert homes that provide a view, light, ventilation, egress and filter the environment. Windows may account for 10 to 25 percent undesirable heat loss or gain to interiors. All desert dwellers can save energy and money by becoming educated in basic principles of solar benefits and user management and control. People relocating from other climates often do not understand window design strategies that ameliorate the extreme desert climate. The design strategies and technology necessary for control is presented in this thesis. This thesis presents current window technology and proven interior and exterior window shading design strategies that save energy yet maintain a pleasant visual and physically healthy interior comfort. Architects, interior designers and residents of the southwest will find this information useful as a decision base for specification of energy efficient windows and design

Unusual cause of acute lower extremity ischemia in a healthy 15-year-old female: A case report and review of popliteal artery aneurysm management in adolescents

Limb ischemia in healthy teenagers is unusual. While traumatic or iatrogenic injury is the most common etiologies of limb ischemia in the pediatric population, anatomic variants such as true aneurysms should be considered [1]. We report the second documented pediatric case of an idiopathic, isolated true popliteal aneurysm resulting in acute limb ischemia in a previously healthy 15-year-old female. We also review the proper evaluation and surgical management of this anatomic anomaly. In this case, surgical management included resection of the aneurysm, reconstruction with reverse saphenous vein grafting, and distal endarterectomies to restore adequate distal blood flow. Ultimately, this patient's limb and function were salvaged with minimal consequences

A case of traumatic rupture of a giant omphalocele and liver injury associated with transverse lie and preterm labor

Perinatal omphalocele rupture is a rare occurrence. We present a case of a baby delivered at 35 weeks with a known giant omphalocele, transverse lie, and the omphalocele downward in the birth canal who suffered rupture of the omphalocele and liver injury around the time of delivery. The pregnancy was complicated by one day of preterm labor, preterm premature rupture of the membranes, and the omphalocele was the presenting part. Despite pulmonary hypertension, rupture of the omphalocele, and a significant liver injury, individualized management with decompression of the liver hematoma allowed successful early closure with mesh followed by delayed reconstruction
