The Canadian Pediatric Surgery Workforce: A 10-year Prospective Assessment.

BACKGROUND: The Canadian Association of Paediatric Surgeons launched a 10-year prospective assessment of the Canadian pediatric surgery workforce and training environment, beginning in 2013. The results of the first 5 years (2013-2017) were previously published. Here, we present the results of the last 5 years (2018-2022), and the cumulative results of the past decade. METHODS: With IRB approval, a web-based survey was sent to all pediatric surgery division chiefs in Canada each year (2013-2022). The survey gathered workforce data on pediatric surgery practices, as well as data regarding fellowship graduates from Canadian training programs. RESULTS: Complete responses were received from all 18 divisions (100% response rate). Over the decade studied, the number of pediatric surgeons and full-time equivalent positions increased from 73 to 81, and 65 to 82, respectively. Thirty positions were vacated (15 retirement, 6 new Canadian practice, 8 leaving Canada, 1 other), and 38 were filled (20 new Canadian fellowship graduates, 8 Canadian surgeons moving from other sites in Canada, 10 surgeons coming from outside Canada). Seventy-five fellows completed training eligible for North American certification, including 34 Canadians, 31 Americans, and 10 non-North American foreign nationals (9 of whom left North America after training). The proportion of Canadian graduates who desired, but could not find, a Canadian position improved from 44% in the first 5 years to 20% in the second 5 years. CONCLUSIONS: The Canadian pediatric surgery workforce has experienced a modest increase over a decade. A mismatch still exists between Canadian pediatric surgery graduates and attending staff positions, but the situation has improved during the last 5 years. TYPE OF STUDY: Survey.

Delayed Diagnosis of a Pyloric Web Causing Gastric Outlet Obstruction in a 13-Month-Old Girl.

Pyloric web is a rare cause of gastric outlet obstruction. Classical pyloric web can be diagnosed by obtaining a patient history, physical examination, and plain abdominal X-ray, whereas a perforated web leads to incomplete intestinal obstruction. Delayed diagnosis is rare, and the definite diagnosis is made by upper endoscopy. In this report, we report a case of a girl in whom a pyloric web was diagnosed at the age of 13 months.

The Canadian pediatric surgery workforce: A 5-year prospective study.

BACKGROUND: In 2014, a survey study of the Canadian pediatric surgery workforce predicted a need for 2 new pediatric surgeons/yr. in Canada. We sought to assess these predictions and evaluate the status of the workforce. METHODS: With IRB approval, a web-based survey was sent to pediatric surgery division chiefs in Canada each year (2013-2017). The survey data included: number of practicing pediatric surgeons, full time equivalent (FTE) positions, and fellowship graduates. RESULTS: There was a 100% response rate (18 divisions). From 2013 to 2017, the number of practicing pediatric surgeons and FTE positions increased (73 to 78, and 64.6 to 67.5, respectively). Eleven positions were vacated (4 retirement, 7 new practice), and 18 were filled. Eight were filled by new Canadian graduates, 7 by Canadians previously working in Canada or abroad, and 3 by European surgeons. Thirty-eight fellows completed training in Canada, including 24 non-Canadians who all left Canada. Nine Canadians who started practicing immediately after fellowship took positions in Canada (5) and the US (4). CONCLUSIONS: Predictions made in 2014 were largely accurate. There has been modest growth in the Canadian pediatric surgery workforce over the last 5 years. A significant mismatch continues to exist between Canadian pediatric surgery graduates and attending staff positions. TYPE OF STUDY: Survey. LEVEL OF EVIDENCE: V.

A survey-based assessment of the Canadian pediatric surgery workforce.

BACKGROUND: There is significant lack of information regarding the Canadian pediatric surgery workforce. METHODS: An IRB-approved survey aimed at assessing workforce issues was administered to pediatric surgeons and pediatric surgery chiefs in Canada in 2012. RESULTS: The survey was completed by 98% of practicing surgeons and 13 of the 18 division chiefs. Only 6% of surgeons are older than 60 years, and only a fifth anticipate retirement over the next decade. The workforce is stable, with 82% of surgeons unlikely to change current positions. Surgical volume showed essentially no growth during the 5-year period 2006-2010. The majority of surgeons felt they were performing the right number or too few cases and anticipated minimal or no future growth in their individual practices or that of their group. Based on anticipated vacancies, the best estimate is a need for 20 new pediatric surgeons over the next decade. This need is significantly surpassed by the current output from the Canadian training programs. CONCLUSIONS: The Canadian pediatric surgery workforce is currently saturated. The mismatch between the number of graduating trainees and the available positions over the next decade has significant repercussions for current surgery and pediatric surgery residents wishing to practice in Canada.

Infantile hypertrophic pyloric stenosis: An association in twins?

BACKGROUND: The etiology of infantile hypertrophic pyloric stenosis (IHPS) remains a mystery. Some suspected risk factors include birth rank, maternal age, sex, family history and monozygosity in twins. Various theories attempt to explain the etiology of IHPS. Scientific research suggests that enteric neuronal damage and nitric oxide synthase dysfunction may be implicated, but the consensus is that environmental modification must exist to account for the variability in its occurrence. METHOD: Four cases of concordant occurrences of IHPS in twins were examined to determine the history and outcome of IHPS development in twins. Three sets were dizygotic and one was monozygotic. Of the eight infants, three were female, including the one monozygotic pair. In all four cases, a time lag existed between the development of symptomatic onset of IHPS in twin A and twin B. In one set, sonographic confirmation, performed because of IHPS diagnosis in the twin sibling, occurred concurrently with onset of vomiting, leading to early surgery before fluid and electrolyte imbalances developed. CONCLUSIONS: Despite the lack of agreement as to whether the cause of IHPS is genetic, environmental or both, the high concordance rate seen in twins is indisputable. Thus, the empirical evidence provides credence to consider examining the asymptomatic co-twin when one of the twins presents with IHPS.

Lawnmower injuries in children: a 10-year experience.

Approximately 77,800 annual lawnmower-related injuries are treated in the USA, with 9,300 involving children. This work reviews the literature and reports our 10-year experience with lawnmower injuries. We retrospectively reviewed patients with lawnmower injuries admitted to the Women and Children's Hospital of Buffalo from 1995 to 2005 and reviewed the literature. Sixteen patients with mower-related injuries were admitted to our institution, with three due to walk-behind mowers and 13 due to riding mowers. The mean age was 7.5 years. Riding mower injuries had a higher average injury severity score (14.3 vs. 9) and a longer average length of hospital stay (15 vs. 2 days). All of the walk-behind mower injuries were extremity injuries, with two requiring amputations. Eleven of the riding mower injuries had extremity injuries alone, one had isolated torso injuries, and one had both extremity and torso injuries. Three required amputations, and the two patients with torso injuries required extensive surgical reconstructions. Pediatric lawnmower injuries, particularly due to riding mowers, are a highly preventable cause of morbidity and mortality. Increased public safety awareness and further manufacturer safety modifications should be strongly encouraged in order to limit this cause of pediatric trauma.

Reduced social morbidity of laparoscopic appendectomy in children.

Laparoscopic appendectomy has not been uniformly adopted by pediatric surgeons. Our children's hospital adopted laparoscopic appendectomy due to perceived benefits to patients and their families. We hypothesized that laparoscopic appendectomy in children resulted in less social morbidity than those undergoing open appendectomy. A questionnaire focused on a set of postoperative variables affecting the patient's and the family's return to normal activities. Families expressed their answers as a range of days. Five different ranges were assigned a numerical value for 10 different social morbidity variables. The numerical values were analyzed using Pearson chi2 test; statistical significance was defined as P < 0.05. The response rate was 55 per cent (134 of 244). Seventy-four had open and 47 laparoscopic appendectomy with a comparable incidence of acute and perforated appendicitis. Children undergoing laparoscopic appendectomy had shorter hospital stays and earlier resumption of feeding, return to school, return to pain-free walking and stair climbing, and resumption of normal activities including gym. Additionally, they had fewer wound problems, shorter duration of oral pain medication usage, and their parents returned to work quicker than the open group. All these were statistically significant. Laparoscopic appendectomy results in significantly reduced social morbidity for children and their families.

Congenital pancreatic cysts in children.

The authors report a case of an 11-year-old girl with a solitary, congenital pancreatic cyst and review the literature. Such cysts are very rare and typically are diagnosed in childhood. As a neonate, this patient's paternal half brother also had undergone resection of a congenital pancreatic cyst. The authors believe this is the first documented familial incidence of a congenital pancreatic cyst.

The respiratory advantage of laparoscopic Nissen fundoplication.

BACKGROUND/PURPOSE: Laparoscopic Nissen fundoplication is replacing the open approach in the treatment of children with gastroesophageal reflux. The postoperative respiratory advantages seem obvious but remain unproven. The authors hypothesized that laparoscopic Nissen fundoplication provides postoperative respiratory advantages in neurologically normal children as well as those with mental retardation or profound neurologic impairment. METHODS: The charts of all laparoscopic Nissen fundoplications over a 4-year period were reviewed. Sixty-one laparoscopic procedures were compared with the most recent 61 consecutive open Nissen fundoplications. The following variables were reviewed: age, weight, gender, preexisting comorbidities, operating time, postoperative pulmonary complications, and length of stay. Categorical data were compared for significance utilizing chi2 cross tabulation. Variables representing numerical data were compared by t test. RESULTS: Although there appeared to be a trend toward sicker patients in the open group, the laparoscopic group showed significantly improved rates of extubation, shorter recovery room stays, shorter durations of chest physiotherapy, fewer intensive care unit admissions, more rapid resumption of baseline feedings, and overall decreased length of stay (P < 0.05). Pulmonary benefits also were noted in the neurologically impaired population when analyzed separately. CONCLUSIONS: Laparoscopic Nissen fundoplication confers a definable benefit with a significant pulmonary advantage in both neurologically normal children and those with neurologic impairment.

New strategies in nonoperative management of meconium ileus.

PURPOSE: The aim of this study was to develop new nonoperative strategies for the management of meconium ileus in an attempt to improve on the current unacceptable failure rate. METHODS: Mice were constipated with subcutaneous morphine injection. Each then received an enema solution (perflubron, surfactant, Tween-80, Gastrografin, Golytely, DNase, N-Acetylcysteine, Viokase, or normal saline). After the enema solution was administered, stool output was quantitated. Histologic examination of the intestines was performed on a second group of mice that also received enemas. Finally, viscosity measurements were taken of human meconium at baseline and after variable incubation periods with each test solution. RESULTS: For relieving constipation in vivo, Gastrografin enema was most efficacious. All agents were equally benign to the intestinal mucosa. In vitro, only 4% N-Acetylcysteine and perflubron were less effective at decreasing meconium viscosity than normal saline at T = 0 hours, with N-Acetylcysteine producing greater reduction in viscosity than normal saline at T = 6 hours. CONCLUSIONS: Our results show that surfactant and Gastrografin are the most effective for the in vivo relief of constipation. This is accomplished without mucosal damage. These agents also significantly reduce viscosity in vitro, and we speculate that they may be beneficial in relieving constipation caused by meconium ileus in cystic fibrosis patients.
