    THE LAPAROSCOPIC DUODENO-DUODENOSTOMY SIMULATOR: A MODEL FOR CUSTOMIZABLE MINIMALLY INVASIVE SURGERY TRAINERS

    ( 7/2014 )

    Podium Presentation: International Pediatric EndoSurgery Group. Basic Science Section
    July 2014- Edinburgh, Scotland.
    Introduction: 
    Simulator training is an important step toward proficiency in minimally invasive surgery (MIS) for pediatric surgeons.  MIS repair of duodenal atresia requires suturing skills that are difficult to acquire.  We sought to develop a prototype of an inexpensive, synthetic, and customized MIS simulator for laparoscopic duodeno-duodenostomy.

     

    Methods:  Two pediatric surgeons, in cooperation with a University Bioengineering Department, designed and developed a synthetic model to simulate laparoscopic duodenal atresia repair in an infant.

     

    Results:  The simulator was constructed in three parts: organ construction, training box construction and assembly.  

    Organ construction:  Solid molds of small intestine, duodenum, stomach and liver were designed in SolidWorks software in ABS plastic using the 3D printer.  The size of each mold was designed to be dimensionally accurate to life-sized infant organs.  TAP premium latex rubber was then dispersed over the plastic molds to construct the organs. The duodenal segments included a layer of thin gauze sandwiched between layers of latex. Training box construction:  The box was modeled after the body cavity of an infant, from the lower neck to the top of the thighs.  The interior volume mimics the pneumoperitoneum of an infant abdomen during laparoscopic surgery.  After constructing a Styrofoam top and bottom frame template that simulated the top and bottom of the infant body, fiberglass resin was painted over the template to construct the body cavity. Three holes designating the placement of a grasper, a needle driver and an endoscope were cut from the top frame.  Top and bottom frames were secured to each other.  Reusable rubber grip was secured over the top frame so the laparoscopic instruments could be placed through it.  Assembly:  Organs were secured in the box with Velcro.  The small intestine, duodenum and stomach were placed in the bottom frame and the liver was placed inside the top frame of the body cavity. A silicone rubber sheet covered the top frame.  The simulator was then ready for placement of the laparoscopic instruments. 

    The simulated duodeno-duodenostomy was judged to be realistic by the surgeons who trialed the simulator.  The material was durable and did not tear or deform after multiple anastomoses.

    Conclusion:  An inexpensive, life-sized and durable synthetic simulator for MIS duodeno-duodenostomy was constructed.  This serves as an initial proof of concept that customizable simulators of pediatric MIS procedures can be constructed using 3-D printing technology and TAP latex to construct organs.  The development of operation-specific simulators has the potential to speed the safe and efficient integration of rare pediatric MIS procedures into practice.

    LATE PRESENTING CONGENITAL DIAPHRAGMATIC HERNIA:  A 21-YEAR SINGLE CENTER REVIEW   J Baerg MD, V Kanthimathinathan MD, D Moores MD Loma Linda University Children’s Hospital, Loma Linda, CA   Aim:  To describe the  outcome of children with late presenting congenital diaphragmatic hernia (CDH) and compare the most recent decade (2000-2009) to the previous decade (1989-1999) for changes in the clinical practice.   Methods:  After IRB approval, patients who presented  with CDH between 30 days and 18 years, between January 1989 and December 2009, were reviewed retrospectively.  Outcome data were collected by telephone survey in 2010. Data were compared by Fisher exact test and t-test. P<0.05 was  significant.   Results:  During the study period, 31 children (22/31(71%) males) presented between 45 days and 13 years (median:  9 months). Morgagni hernia was present in 14/31(45%) and Bochdalek in 17/31(55%).  There were 20/31(64%) left-sided, 8/31(26%) right-sided and 3/31(10%) bilateral.  Acute symptoms were present in 24/31(77%), chronic symptoms in 5/31(17%), and 2/31(6%) had an incidental diagnosis of CDH.  There were 10/31(32%) misdiagnosed as pneumonia, one patient having undergone a prior thoracotomy for empyema at another center.  There was 1/31(3%) misdiagnosed as a chest mass, who required extensive intestinal resection after strangulation in a left Bochdalek hernia.  Between 1989-1999, 14/31(45%) open repairs were performed, 2/14(14%) with patch.  Between 2000-2009, 17/31(55%) repairs were performed, 7/17(41%) laparoscopic.  Blood loss (p=0.04), post-op ventilation (p=0.004) and hospital stay (p= 0.04) were significantly higher between 1989-1999.  Operative times were significantly longer (p=0.005) between 2000-2009.  Telephone follow-up was complete for 27/31(87%) and ranged from 1-20 years (median: 7 years).  All survived, none had surgery for recurrence, malrotation or bowel obstruction. The child with bowel strangulation is alive at 18 years with short bowel on TPN.   Conclusion:  Patients with repaired, late presenting CDH survive  without sequellae, unless misdiagnosis occurs.  Clinical practice is improving.   The most recent decade demonstrates significant improvements in length of stay, operative blood loss and use of postoperative ventilation.  The increased operative times reflect the learning curve of laparoscopic repairs.

      Aim:  To identify factors associated with residents who attained a predetermined level of competence in laparoscopic intracorporeal suturing. Methods:  IRB approval was obtained.  Data was gathered prospectively between July 1, 2009 and March 1, 2010.  A goal was set that residents would practice intracorporeal suturing in a simulator until they could perform one surgeon’s knot and five more throws in under 5 minutes.  Residents from 5 postgraduate years presented individually for a tutorial with one pediatric surgeon.  Residents first practiced the movements outside the simulator.  When they could produce the movements with a needle driver and forceps, they proceeded to the simulator.  They practiced individually with one pediatric surgeon until they could perform an intracorporeal suture.  Baseline times were recorded.  A survey about previous laparoscopic experience   was given to each resident.  Each was then instructed to continue to return to the simulator to practice until they could perform an intracorporeal suture  within the goal time of 5 minutes.  Besides this predetermined speed, they were instructed to practice until they did not drop the needle and could keep the instrument tips within an 8 by 8 cm area.  Logs to keep track of practice dates and times were administered. Data from surveys, official case logs, and practice time logs were analyzed by Pearson chi-square and student t-test.  P-values <0.05 were considered significant.  Results:  Forty residents presented for tutorials.  Fourteen (35%) reached the goal during the study period and they required between 1 and 21 (median: 1.5) practice sessions.                         * mean, SD Conclusion: Residents that achieved competence in laparoscopic intracorporeal suturing (as compared to those that did not) were 1) significantly more likely to have had 3 or more years of post-graduate training, 2) significantly more experienced with complex laparoscopic cases, and 3) sutured twice as fast at the time of their initial tutorial.     Met Goal n = 14(%)    Goal Not Met n =26(%) p Post Graduate Year 3- 5 12(86%) 2(8%) 0.01 Complex Lap.

     ABSTRACT:       INTRODUCTION:   We present a case of endoscopy-guided placement of a pleuro-peritoneal shunt in a patient with primary lymphedema, multiple abdominal lymphoceles, an episode of spontaneous bacterial peritonitis and  recurring symptomatic  pleural effusions.CASE:  A fifteen year-old boy with primary lymphedema, had undergone multiple thoracenteses and chest tubes for a left pleural effusion.  An incision was made in the posterior axillary line at the sixth intercostal space.  The pleural portion of the shunt was placed in good position guided by the five millimeter, thirty-degree camera.    The shunt and pump chamber were tunneled under the skin.  A 5mm incision was made in the left upper quadrant, a purse string suture was placed in the posterior rectus sheath and the 5mm port was inserted into the abdomen under direct vision.   Pneumoperitoneum was obtained to a pressure of 13 mm Hg and the camera was inserted.  Multiple lymphoceles and   adhesions were identified. With laparoscopic guidance, an area was dissected in which to place the shunt.  Immediate good shunt function was observed.DISCUSSION:  This previously unreported use of endoscopy to successfully place a pleuro-peritoneal shunt, allowed a patient to be discharged from hospital free of oxygen and external tubes.    Information was obtained about the patient’s abdomen  which will guide future therapy.

    Abstract

    Objective

    To compare the long-term outcome in children with one Nissen fundoplication to those with redos for gastroesophageal reflux disease (GERD).

    Methods:

    After IRB approval (#5100277), children younger than 18 years, from two children’s hospitals, with Nissen fundoplications or redos performed between January 1995 and March 2011 were retrospectively reviewed.  Follow-up data were collected by phone calls to caregivers in December 2012.  Outcome variables were:  pneumonia admissions, vomiting, retching, state of fundoplication on contrast radiograph, feeding by gastro-jejunal (GJ) feeding tube, laparotomy for adhesive bowel obstruction, administration of anti-GERD medications, and mortalities.  Children with one fundoplication were compared to those with redos using t-tests for continuous and chi-square tests for categorical variables.  A p-value <0.05 was considered significant.

    Results:

    The families of 212 were contacted (54% male), 181 had one fundoplication (85.4%) and 31 had redos (14.6%).  The median follow-up for the cohort was 3.4 years (range: 0.5-16 years).  The median time to first redo was 17 months (range: 1-108 months) and to second redo for 3/31(9.7%), it was 32.5 months (range: 23-69 months).  At follow-up evaluation, children with redos had significantly more hospital admissions for pneumonia (p<0.022), wrap herniation on contrast radiographs (p<0.001), vomiting and retching (p<0.001).  A significantly greater number with redos were fed by GJ feeding tubes (p<0.001) and required more laparotomies for adhesive bowel obstruction (p=0.043). 

    Conclusion:

    Children with redos have significant difficulties compared to children with one fundoplication. They have significantly more admissions for pneumonia, vomiting, retching, wrap herniation and gastrojejunal feeding tubes at follow-up evaluation.

  • Baerg, Deming  The Contribution of GERD to Weight Loss in NICU Infants    Podium Presentation (3 minutes)  American Pediatric Surgery Association   Orlando, Florida  May 22, 2010 ( 5/2010 )
    Purpose:              We sought to identify significant associations between gastroesophageal reflux disease (GERD) and weight loss in neonatal intensive care unit (NICU) infants. Methods:              After Institutional Review Board approval, infants born between January 2004 and December 2006, investigated by 24-hour pH-probe before age six months, were reviewed retrospectively. GERD was present if the pH < 4 for over 5% of 24 hours.  We examined growth curves at the initial pH-probe, 6 months later, and December 2009.  At the six-month evaluation, we compared infants who lost to infants who gained.  Logistic regression identified subgroups associated with weight loss independent of GERD.  Results:             Follow-up was complete for 191, 48(25.1%) lost and 143(74.9%) gained.  GERD was present in 87/191(45.5%), 31(35.6%) underwent fundoplication, 56(64.4%) received anti-reflux medications. Weight loss occurred in 21/87(24.1%) and was not from GERD in 20/21(95.2%). Between 6-30 months (median:  10 months) after their initial probe, 5/31(16.1%) fundoplication patients were vomiting, but gaining weight.  A pH-probe confirmed GERD.             GERD was absent in 104/191(54.5%). Weight loss occurred in 27/104(26.0%) and was not from GERD in 20/27(74.1%). Between 6-31 months (median: 11 months) after a negative probe, 7/27(26.0%) were vomiting and losing weight.  A pH-probe confirmed GERD.             Infants unable to feed orally (OR:2.68(95%CI:  1.24-5.85)), or with a genetic syndrome (OR:13.56(95%CI:  4.56-40.29)), lost independent of GERD. Conclusions:              If treated, GERD is not associated with weight loss in NICU infants.  Despite a negative pH-probe, pediatricians should inquire about GERD symptoms, and restudy infants before weight loss occurs.  Infants with inability to feed orally or genetic syndromes lose weight, independent of GERD.

     Chronic Intestinal Pseudo-obstruction in Children Joanne Baerg MD, Arvand Elihu MD    Loma Linda University Children’s Hospital       Background: The aim of this study was to report the presentation and outcome of 20 consecutive children with the syndrome of chronic intestinal pseudo-obstruction between 1995-2005.  Methods:IRB approval was obtained.  Charts of patients <17 years with recurrent signs of intestinal occlusion in the absence of identifiable obstruction were reviewed.  Hirschsprung’s disease was excluded.Results:Twelve girls (60%) and 8 boys (40%) were identified.  Twelve (60%) presented before one year (range: 3 months-10 years).  Three underwent ileostomy (15%).  Follow-up ranged from 1.5-17 years (mean -9years).  One boy suffered Munchausen’s by proxy.  The remaining 19 were categorized:  1)  Three (15%) had pathologic evidence of myopathy(2) and neuropathy (1).  2)  Twelve (60%) had non-specific intestinal failure, 8(66%) were neurologically impaired and had GERD.  The intestinal failure worsened after Nissen fundoplication in 3 (25%).  3)  Four (20%) actually had a slowly evolving mechanical obstruction which resolved after surgery.  Overall mortality was 20% (4/20).  Presently, 10 (50%) tolerate enteral feeds and 6 (30%) require parenteral nutrition.   Conclusion:Three children (15%) had pathologic evidence of pseudo-obstruction.  Intestinal failure can occur despite normal histology.  A slowly evolving mechanical obstruction can mimic pseudo-obstruction and should be eliminated from the diagnosis.

(0.177 caliber ball bearing and low velocity weapons- 280 feet per sec.)   One patient was left unsupervised with an older sibling and one was the victim of child abuse. Each presented with a 3mm opening on the anterior abdominal wall and no exit wound. Vital signs remained within normal limits throughout the assessment and no other injuries were noted. Triple contrast abdominal CT scans and serial abdominal X-rays of each patient remained completely unremarkable. In spite of normal investigations, serial abdominal exams revealed peritoneal irritation within a short period of time after arrival.  Laparotomy was performed in each case and findings will be described.  The cases illustrate the potential lethality of air rifles and the importance of accurate, frequent clinical exams over radiological studies in order to prevent missed injuries.     Address correspondence to Dr. Baerg Email:       jbaerg@som.llu.edu Phone:      909 558 4619, Fax:  909 558 0236
