A Minimally Interventional Approach to Oesophageal Atresia Repair With Early Enteral Feeding is Safe, Optimises Neonatal Outcomes, and Reduces Resource use.

PURPOSE: Recent series of newborn Oesophageal Atresia (OA) repair continue to report widespread use of chest drains, gastrostomy, routine contrast studies and parenteral nutrition (PN) despite evidence suggesting these are superfluous. We report outcomes using a minimally interventional approach to post-operative recovery. METHODS: Ethically approved (15/WA/0153), single-centre, retrospective case-note review of consecutive infants with OA 2000-2022. Infants with OA and distal trache-oesophageal fistula undergoing primary oesophageal anastomosis at initial surgery were included (including those with comorbidities such as duodenal atresia, anorectal malformation and cardiac lesions). Our practice includes routine use of a trans-anastomotic tube (TAT), no routine chest drain nor gastrostomy, early enteral and oral feeding, no routine PN and no routine contrast study. Data are median (IQR). RESULTS: Of total 186 cases of OA treated during the time period, 157 met the inclusion criteria of which 2 were excluded as casenotes unavailable. TAT was used in 150 infants. A chest drain was required in 13 (8%) and two infants had a neonatal gastrostomy. Enteral feeds were started on postoperative day 2 (2-3), full enteral feeds established by day 4 (4-6) and oral feeds started on day 5 (4-8). PN was required in 15%. Median postoperative length of stay was 10 days (8-17). Progress was quicker in term infants than preterm. One infant died of cardiac disease prior to neonatal discharge. Two planned post-operative contrast studies were performed (surgeon preference) and a further 7 due to clinical suspicion of anastomotic leak. Contrast study was therefore avoided in 94%. There were 2 anastomotic leaks; both presented clinically at day 4 and day 8 after oral feeds had been started. CONCLUSION: Our minimally interventional approach is safe. It facilitates prompt recovery with lower resource use, reduced demand on nursing staff, reduced radiation burden, and early discharge home compared to published series without adversely affecting outcomes. LEVEL OF EVIDENCE: Level 4.

Implementing an early feeding pathway post gastrostomy insertion reduces inpatient stay.

BACKGROUND: There is no consensus regarding optimal postoperative feeding strategy following gastrostomy insertion in children. The aim of this study was to determine whether implementing an early postoperative feeding pathway reduces length of stay (LOS) without increasing complications. METHODS: A retrospective case note review of all children having a new gastrostomy inserted during a one-year period prior to (July 2016-July 2017) and following (July 2017-July 2018) pathway introduction was performed. Children unable to follow the pathway for coexisting medical or nutritional reasons were excluded. The pathway comprised feeding 50% of normal feed 2 hours postprocedure, followed by 100% of normal feed at 5 and 8 h. Previously, patients were fed postoperatively according to surgeon preference. RESULTS: 116 cases met inclusion criteria, 55 prior to and 61 after pathway implementation. Children following the early feeding pathway had a shorter postoperative LOS than the historical group (median 28 vs 33 h, p < 0.003), while immediate (<72 h) and early (<30 day) complication rates were similar (8.2 vs 7.3%, p = 1.00 and 12 vs 16%, p = 0.59, respectively). CONCLUSIONS: Early postoperative feeding after gastrostomy insertion is safe and reduces LOS. TYPE OF STUDY: Quality improvement. LEVEL OF EVIDENCE: III.

Outcomes following laparoscopic inguinal hernia repair in infants compared with older children.

PURPOSE: Indications for laparoscopic inguinal hernia repair in infants and children remain controversial. The purpose of this study is to compare clinical features and outcome of laparoscopic inguinal hernia repair in infants with older children. METHODS: Retrospective single centre review of all patients <16 years of age (n = 380) undergoing laparoscopic inguinal hernia repair over a 5-year period (Jan 2005-Dec 2009). Outcomes were compared between infants (≤ 12 months of age) with older children (1-15 years). RESULTS: There was a trend towards higher recurrence rate in older children than in infants (4 % vs. 1 %; p = 0.17). Total complications and complications requiring surgery were similar in both age groups. There was one testicular atrophy in an infant who had an incarcerated inguinal hernia. The incidence of bilateral inguinal hernia and contralateral patent processus vaginalis (PPV) were both significantly higher in infants (total 61 % compared with 35 % in older children). CONCLUSIONS: Laparoscopic inguinal hernia repair in infants is safe and carries acceptable complication and recurrence rates. The laparoscopic approach may be particularly beneficial in infants since it allows simultaneous closure of a contralateral PPV and bilateral herniae. The outcome of laparoscopic inguinal hernia repair in older children requires further evaluation.

Surgery for hydrocele in children-an avoidable excess?

BACKGROUND: There is little consensus over the optimal timing of ligation of a patent processus vaginalis (PPV) in boys with hydrocele. We hypothesized that a proportion of procedures may be unnecessary because they are performed at an age before which the PPV may be expected to close spontaneously. Such excess may expose the child to unnecessary surgery and have significant cost implications. METHODS: A systematic literature review relating to timing of PPV ligation and a population-based study to define number of PPV ligations performed annually in England and age at surgery were conducted. RESULTS: Most hydroceles resolve before 2 years of age, but their natural history beyond this age is poorly documented. Current guidelines recommend PPV ligation at 2 years of age. An average of 2878 operations for hydrocele is performed per year in children in England. Commonest age at repair is 2 years. There are no randomized controlled trials comparing PPV ligation with an observational nonoperative approach. CONCLUSIONS: The natural history of hydrocele is poorly documented beyond the age of 2 years. There is no good evidence to support current practice. Delaying surgery may reduce the number of procedures necessary without increasing morbidity. A prospective study to investigate this is warranted.

The predictive value of preoperative fluorine-18-L-3,4-dihydroxyphenylalanine positron emission tomography-computed tomography scans in children with congenital hyperinsulinism of infancy.

BACKGROUND/PURPOSE: In congenital hyperinsulinism (CHI) of infancy, the use of preoperative fluorine-18-L-3,4-dihydroxyphenylalanine-positron emission tomography-computed tomography ((18)F-DOPA-PET-CT) scan has recently been reported. The aim of this study was to evaluate the accuracy of this technique in discriminating between diffuse and focal CHI and the anatomical localization of focal lesions. METHODS: Between 2006 and 2010, (18)F-DOPA-PET scan was performed in 19 children with CHI (median age, 2 months; range, 1-12 months) who were not responding to medical therapy and underwent laparoscopic or open surgery. The findings of (18)F-DOPA-PET scan were correlated with histology. RESULTS: In 5 children, (18)F-DOPA-PET scan showed diffuse pancreatic uptake, confirmed at histology and supporting the genetic suspicion of diffuse disease. In 14 children, (18)F-DOPA-PET scan indicated focal pancreatic uptake, which corresponded to histology. However, in 5 patients (36%), (18)F-DOPA-PET scan was inaccurate in defining the location of the lesion (n = 3), size of the lesion (n = 1), or both location and size (n = 1), leading to an inaccurate pancreatic resection. CONCLUSIONS: Fluorine-18-L-3,4-dihydroxyphenylalanine-positron emission tomography-computed tomography scan discriminates between diffuse and focal forms of CHI. In focal forms, (18)F-DOPA-PET scan is useful in 2/3 of patients in defining the site and dimension of the focal lesion. Intraoperative histologic confirmation of complete focal lesion resection is needed.

Surgical outcomes of esophageal atresia without fistula for 24 years at a single institution.

PURPOSE: The aim of the study was to evaluate the surgical outcome of esophageal atresia (EA) without fistula for 24 years at a single tertiary center for pediatric surgery. METHODS: The study used a retrospective chart review of infants diagnosed with EA without fistula between 1981 and 2005. RESULTS: Of 33 patients with EA without fistula, 31 charts were available. Mean birth weight was 2327 g (range, 905-3390 g), and 71% were male. Most common associated anomalies were cardiac (n = 6; 19%) and renal (n = 5; 16%), followed by vertebral (n = 4; 13%) and anorectal (n = 2; 7%). The median initial esophageal gap was 5 vertebral bodies. Six had a primary repair, and 25 patients had esophageal replacement at a median age of 7 months. This involved gastric transposition in 20 (1 followed failed jejunal interposition), colonic interposition in 5, jejunal interposition in 1 (after a failed colonic), and repair at another center in 1. With a median review of 9 years, 21 patients had long-term sequelae with the need for multiple further surgical procedures including an antireflux procedure in 5. One patient died. CONCLUSIONS: Management of EA without fistula remains challenging. Most patients required staged treatment that included esophageal replacement. The frequency of late complications indicates the need for programmed long-term review.

Outcomes of the "clip and drop" technique for multifocal necrotizing enterocolitis.

BACKGROUND: The "clip and drop" (CD) has been proposed as a useful strategy in the management of severe multifocal necrotizing enterocolitis (NEC). There is little published data on clinical outcomes after this intervention. We report a 2-center experience with this technique. METHODS: A retrospective review of infants who underwent CD between 1998 and 2006 at 2 tertiary pediatric surgery centers. Data recorded included intestinal resections, interval between laparotomies, anastomoses at subsequent surgery, time to full feeds, and complications including mortality. Data are reported as median with ranges. RESULTS: Thirteen infants (7 male, 6 female) with a birth weight of 811 (514-2110) g underwent CD of up to 5 bowel segments. In 8 of 9 early survivors, all CD segments were viable. Six patients (46%) were alive at 29 (9-96) months. Survivors underwent 4 (3-4) laparotomies and 4 (2-6) bowel anastomoses and had intestinal continuity restored at 67 (51-162) days. CONCLUSIONS: With multiple interventions, half the infants in this high-risk group survived and achieved full enteral feeds. The CD is a valuable technique in a selected group of infants with fulminant NEC.

Bacterial counts from hospital doctors' ties are higher than those from shirts.

Doctor ties are often contaminated with bacteria, and it has been suggested that they should not be worn. We have compared bacterial counts from the ties and shirt pockets of 50 doctors. Counts were higher (P = .002) from ties that were rarely, if ever, cleaned than from shirts that were washed every 2 days or more frequently. The results support the need for further research on unwashable clothing of hospital staff.

The surgical approach to esophageal atresia repair and the management of long-gap atresia: results of a survey.

The optimal approach for esophageal atresia (OA) repair and technique used for long-gap OA repair are controversial. There are few data comparing the outcomes of the different approaches and techniques. We performed a survey of current practice of 88 pediatric surgeons and asked experts to provide us with definitions and rationales behind their management strategies. There were no differences between UK and non-UK surgeons. Although the majority of pediatric surgeons perform minimally invasive surgery (68%), only 16% have performed thoracoscopic OA repair; however, 46% are planning to carry out thoracoscopic OA repair. Gastric interposition is the most preferred technique for long-gap OA when primary anastomosis is not possible, with 94% of those surgeons who use the technique satisfied with it. Growth of the esophageal ends by traction is the other major technique used, but only 76% of surgeons who use it are satisfied with it. Most surgeons repair < or =2 patients with long-gap OAs per year. Long-gap OA should be managed by a limited number of surgeons at each center. Even among experts, there is little consensus on the definition of or the optimum technique for repair of long-gap OA.
