Randomized controlled trial to evaluate the rate of successful neonatal endotracheal intubation performed with a stylet versus without a stylet.

INTRODUCTION: Neonates in intensive care units often require endotracheal intubation and mechanical ventilation. During this intubation procedure, a stylet is frequently used along with an endotracheal tube. Despite the widespread use of a stylet, it is still not known whether its use increases the intubation success rate. This study examined the association between stylet use and the intubation success rate in surgical neonates. METHODOLOGY: This single-center study was conducted between December 2021 and December 2022 in the Neonatal surgical intensive care unit of a tertiary care center in Northern India. Infants were randomized to have the endotracheal intubation procedure performed using either an endotracheal tube alone or with a stylet. The primary outcome of the study was to assess the successful first-attempt neonatal endotracheal intubation rate with and without using a stylet. Apart from the rate of successful intubation, the duration of the intubation and complications during the intubation procedures as measured by bradycardia, desaturation episodes, and local trauma were also recorded. Both groups were thus compared on above mentioned outcomes. RESULTS: The total number of neonates enrolled were 200, and the overall success rate (81% in the stylet group vs. 73% in the non-stylet group) was not statistically significant. Intubation time was however less, when stylet was used (16.2 ± 4.3 vs. 17.5 ± 5.0 s, p = .046). When the endotracheal tube size was 3 or less, the success rate was substantially higher in the stylet group (80%) than the non-stylet group (63%), p = .03. No statistical difference was recorded for bleeding and local trauma, though the esophageal intubation rate was higher when intubation was attempted without the stylet. CONCLUSION: Endotracheal intubation using a stylet did not significantly improve the success rate of the procedure, however, intubation time significantly varied between groups and in different conditions. The rigidity and curvature provided by the stylet may facilitate the process of intubation when smaller caliber endotracheal tubes are used.

Factors affecting stress levels in parents of surgical neonates: A prospective observational study.

BACKGROUND: There is a paucity of research focusing on the stress levels in parents of newborns undergoing surgery. Resource challenged systems have to deal with overcrowding, a shortage of workforce along with demographic and socioeconomic issues like delayed presentations and out of pocket expenses. The primary objective of this study was to understand the factors associated with stress in the parents of these congenitally malformed neonates. METHODOLOGY: This was a prospective cohort study, which was conducted in a neonatal surgical ICU of a tertiary care teaching hospital. Factors affecting stress levels in parents of surgical neonates were studied in 100 participants. A multi-dimensional questionnaire - The PSS: NICU score was utilized in the study. The parents were interviewed on Day 3-5 after surgery. RESULT: 59% of the respondents were fathers. The majority of the parents were in the age bracket of 24 to 35 years. The mean scores for the subscales sights and sounds, looks and behavior and alteration in the parental role were 3.24±0.8, 3.52±0.63, 3.55±0.8 and 2.8 ± 0.9 respectively. The highest level of stress was found in the domains of alteration of parental role and infant appearance and behavior. Comparisons showed significantly higher maternal scores in all the domains. Overall stress scores were highest for abdominal wall defects. CONCLUSION: Parents of neonates undergoing surgery suffer from significant stress levels and appropriate counseling targeted towards specific stressors is required to allay this important parental issue.

Consensus on the Management of Posterior Urethral Valves from Antenatal Period to Puberty.

The need for successful management of posterior urethral valves always captivates the minds of pediatric surgeons. Its success, however, depends on several factors ranging from prenatal preservation of upper tracts to postoperative pharmacological compliance. Regardless of measures available, some cases do not respond and progress to end stage. The management depends on several issues ranging from age and severity at presentation to long-term follow-up and prevention of secondary renal damage and managing valve bladder syndrome. This article is based on a consensus to the set of questionnaires, prepared by research section of Indian Association of Paediatric Surgeons and discussed by experienced pediatric surgeons based in different institutions in the country. Standard operating procedures for conducting a voiding cystourethrogram and cystoscopy were formulated. Age-wise contrast dosage was calculated for ready reference. Current evidence from literature was also reviewed and included to complete the topic.

Acquired-B phenomenon in a neonate presenting with necrotizing enterocolitis.

OBJECTIVE: We are reporting a case of acquired B phenomenon in a 14 days old pre-term baby presenting with necrotizing enterocolitis (NEC) where it was detected as an ABO discrepancy. METHOD: The forward and reverse grouping was done using tube technique as well as column agglutination technique (ABD card and LISS Coombs AHG gel cards, Biorad, Switzerland). The direct antiglobulin test (DAT) was also done on gel card. Further work up was done using acidified (0.1 N HCl) anti-B (pH 6-6.5) polyclonal anti-B (from group A donors) for resolution of ABO discrepancy. RESULTS: The forward grouping was AB RhD positive with a 'mixed-field' agglutination with anti-B. The reverse grouping using pooled A cells, B cells and O cells gave 'negative' result with both the techniques. Anti-A1 gave 2+ agglutination, anti-H gave 1+ agglutination and autologous control was negative. The DAT was also negative. The patient's previous group on day 1 of life was A RhD positive and had received 1 PRBC (pedibag) transfusion. As the patient's blood culture was positive for Klebsiella pneumoniae, it could have contributed to 'acquired-B' phenomenon. Acidified (0.1 N HCl) anti-B (pH 6-6.5) and polyclonal anti-B yielded no agglutination with patient red cells. The patient was kept on antibiotics subsequently and the blood group after 3 weeks was found to be A RhD positive. CONCLUSION: This case of 'acquired-B' phenomenon in a neonate with NEC emphasizes the relevance of clinical findings as a guide to resolve blood group discrepancy and deciding further transfusion strategy.

Omphalocele and epigastric heteropagus: implications and treatment.

In heteropagus twins, the parasitic twin is incompletely formed which is attached to the autosite. We report a case of epigastric heteropagus twins with omphalocele. The parasite had two lower limbs, a rudimentary upper limb, genitalia with developed phallus and scrotum but absent testis. An omphalocele was present just below the attachment of the parasitic twin. A single kidney with ureter and a bladder filled with urine seen during exploration. The parasite bowel was attached to a sleeve of liver tissue from the autosite within the omphalocele sac and this connection was also the main source of its blood supply. Less than 20 cases of omphalocele with EH have been reported previously. The thin sac with underlying adherent bowel led us to go ahead with surgery in the neonatal period for both, excision of epigastric heteropagus and omphalocele repair. The rectus sheath around the omphalocele sac helped in the final wound closure.

Erb's palsy complicating a case of annular pancreas.

We report an unusual presentation of annular pancreas with pneumoperitoneum in a newborn with an associated left sided Erb's palsy. The neurological deficit caused considerable confusion in the diagnosis and unexpected complications after surgery. We highlight the importance of clinical examination and the complications that an Erb's palsy can cause. This unusual triad of Erb's palsy, eventration of diaphragm and annular pancreas has hitherto not been described in literature.

Endoscopic Management of Vesicoureteral Reflux and Long-term Follow-up.

OBJECTIVE: To report our experience with endoscopic management of vesicoureteral reflux (VUR) by injection of a tissue bulking substance - Dextranomer/ hyaluronic acid co-polymer at vesicoureteric junction. DESIGN: Retrospective analyses of case records. SETTING: Pediatric Surgery department in a tertiary care government Institute. PARTICIPANTS: 500 children (767 renal units) consecutively referred to the out-patient department with vesicoureteral reflux noted on micturating cysto-urethrogram (MCU) over a period of 13 years (2004-2016). INTERVENTION: Preoperative VUR grading and renal scars on radionuclide scans were documented. Dextranomer hyaluronic acid copolymer was injected through a cystoscope at the vesicoureteral junction as a day care procedure under short anesthesia. Patients were followed (average duration 27.3 mo) with clinical assessment, periodic urine cultures and renal scans. MAIN OUTCOME MEASURE: Cessation of VUR and symptomatic relief / clinical success postoperatively at 3 months. RESULTS: Complete symptomatic relief was obtained in 482 (96.4%) patients. In 681 units where MCU was available, 614 (90%) units showed resolution of VUR. CONCLUSIONS: Endoscopic injection of tissue bulking substances at vesicoureteric junction to stop VUR seems to be an effective intervention.

Is urodynamic evaluation a must in all operated cases of open neural tube defects.

BACKGROUND: Spina bifida is a common cause of pediatric neurogenic bladder. It causes renal failure in almost 100% of patients if the associated detrusor sphincter dyssynergia (DSD) is inadequately managed. Detrusor instability and high detrusor pressures (Figure) have been implicated as the major factors predictive of renal damage in these patients. Urodynamic studies provide early identification of "at risk" kidneys so that appropriate intervention can be made. However, the role in post-operative patients of spina bifida who have no clinical manifestations remains unclear. OBJECTIVE: To study the bladder dynamics in asymptomatic post-operative patients of spina bifida and to determine whether routine urodynamic study is justifiable. MATERIAL AND METHODS: Urodynamics was performed on 15 operated patients of spina bifida who did not have any neurological deficit and were asymptomatic. RESULTS: The mean age of the patients was 4.97 years. None of the patients had any urological complaints with their ultrasonography being normal. None had scars on nuclear scan. Of the 15 patients, 12 (80%) had abnormal findings on urodynamic assessment. Three patients (20%) had detrusor pressures greater than 40 cm of H2O. One patient had significant residual urine and detrusor instability. DISCUSSION: The use of urodynamic studies in asymptomatic patients of spina bifida remains controversial, with one school of thought advocating early invasive urodynamic testing. In contrast, some favor noninvasive sonological monitoring, reserving invasive tests only for patients with renal tract dilatation. In our subset of patients none had renal tract dilatation but three patients (20%) had "at risk" bladders. These patients would benefit from early intervention aimed at renal preservation. The study is limited by a small sample size because of the relative rarity of the patient profile included. A further multicenter study with a case-control design could conclusively indicate the role of urodynamic testing in these patients. CONCLUSION: Patients of spina bifida, even when asymptomatic, have a high incidence of unsafe bladders. Early identification and appropriate measures can protect kidneys from long-term damage, hence urodynamic profiling is mandatory for identification of potentially high-risk bladders.

Role of glycopyrrolate in healing of anastomotic dehiscence after primary repair of esophageal atresia in a low resource setting-A randomized controlled study.

AIMS: To investigate the role of glycopyrrolate in decreasing oral secretions in patients of esophageal atresia (EA) with anastomotic leak and evaluate its effect on healing of anastomotic dehiscence. METHODS: The study comprised consecutive neonates of esophageal atresia, who had undergone primary surgery and developed anastomotic leak. The patients were randomized into two groups with the observer blinded to the group. The patients in the treatment group were administered glycopyrrolate in the dose of 8 µg/kg 8 hourly, whereas placebo group patients were injected normal saline only. Neonates, in both the groups, were managed conservatively based on the clinical and radiological parameters. The end points of the study were either resolution or progression of the leak. The study was approved by the institute ethics committee. RESULTS: There were 21 patients each in two groups with comparable preoperative characteristics. All the cases had anastomotic leaks clinically detectable in the chest tube. Saliva alone constituted the leak material in 18 cases in the treatment group and 10 in the placebo group. Cumulative total of mean chest tube output per patient for all patients in the treatment group was 124.15ml as compared to 370.27ml in the placebo group (p=0.001). Anastomotic leak stopped in 16 cases (76%) in the treatment group, as compared to 6 cases (29%) in the placebo group (p=0.004). The postoperative ventilation was required in 8 cases (8/21, 38%) in the treatment group and 17 cases (17/21, 81%) in the placebo group (p=0.010). In the treatment group, the diversion procedures were carried out in 2 out of 21 cases (10%), whereas in the placebo group, 52% of the patients (11/21) required such an intervention (p=0.003). At the time of discharge, the oral feeds could be started in 15 cases (15/21, 71%) in the treatment group, as compared to 3 (3/21, 14%) in the placebo group (p=0.0004). CONCLUSIONS: Administration of glycopyrrolate in patients of anastomotic leak after primary repair of esophageal atresia resulted in reduced oral secretions, which helped in healing of the anastomotic dehiscence in a significant number of patients.

Role of gabapentin and anticholinergics in management of neurogenic bladder after repair of spina bifida - a randomized controlled study.

BACKGROUND: Anticholinergics are well established in the management of neurogenic bladders. However, some patients do have sub-optimal response or severe side effects. This study is designed to assess and compare efficacy of gabapentin with oxybutynin in neurogenic bladders after surgery for spina bifida. METHODS: Patients were randomized into three groups after urodynamic studies and started on oxybutynin, gabapentin, and combination of both, respectively. Thorough clinical and urodynamic reassessment was done at 6months and one year after starting treatment. RESULTS: Forty-four patients (3-19years) were studied. Improvement was noted in symptoms as well as urodynamic parameters in all groups. Maximal improvement of symptom score was with combination of drugs at 1year. In urodynamic studies, compliance, pressures, and capacity showed improvement, which was significant between the groups at both six months and 1year for bladder pressures and volume. Improvement in compliance though marked was not statistically significant. Best response was seen in group receiving both drugs. Gabapentin was better tolerated than oxybutynin. CONCLUSION: Gabapentin is a good alternative to oxybutynin for management of neurogenic bladder, both as monotherapy and as an add-on therapy. It has potential application in patients with inadequate response to anticholinergics. LEVEL OF EVIDENCE: prospective competitive treatment study - level II.

Esophageal perforations due to foreign body impaction in children.

AIMS: The treatment of perforating esophageal foreign body impaction (FBI) is complex and unclear. We present the outcome of surgical treatment of esophageal perforations due to FBI in children along with a management algorithm. METHODS: During a period of 7 years, 7 cases of esophageal perforations due to foreign body (FB) ingestion were referred to our unit. We analyzed the FB types, lodging duration and location, complications, and the surgical approaches. RESULTS: There were 4 male and 3 female patients. Mean age was 28 months (5 months-6 years). Six patients had metal FBs of variable shapes and 1 had glass marble. Three patients had witnessed history of FB ingestion. Duration of ingestion was variable and unknown in half of the patients. The site of impaction was cervical (1) and thoracic (5) esophagus. One patient had a marble as FB in the superior mediastinum. One patient manifested with features of perforation after removal of the impacted FB and 5 patients presented with perforations. Two patients presented with subcutaneous emphysema. One patient had trachea-esophageal fistula (TEF) after disc battery ingestion. Rigid esophagoscopy failed in 4 out of 6 patients. Five patients underwent thoracotomy, and repair with a pleural patch reinforcement. One patient had lateral esophagotomy in the cervical esophagus for removal of the impacted FB. Mediastinal FB was removed without opening the esophagus. All the patients were discharged uneventfully. CONCLUSIONS: Esophageal perforation following FBI is rare and requires prompt treatment. Surgical treatment tailored to the needs of individual patients is associated with a successful outcome and decreased morbidity.

Chronic intestinal pseudo-obstruction: systematic histopathological approach can clinch vital clues.

The histopathological approach of chronic intestinal pseudo-obstruction (CIP) is critical, and the findings are often missed by the histopathologists for lack of awareness and nonavailability of standard criteria. We aimed to describe a detailed histopathological approach for working-up cases of CIP by citing our experience. Eight suspected cases of CIP were included in the study to determine and describe an approach for reaching the histopathological diagnosis collected over a period of the last 1.5 years. The Hirschsprung's disease was put apart from the scope of this study. A detailed light microscopic analysis was performed along with special and immunohistochemical stains. Transmission electron microscopy was carried out on tissue retrieved from paraffin embedded tissue blocks. Among the eight cases, three were neonates, one in the pediatric age group, two adolescent, and two adults. After following the described critical approach, we achieved the histological diagnoses in all the cases. The causes of CIP noted were primary intestinal neuronal dysplasia (IND) type B (in 4), mesenchymopathy (in 2), lymphocytic myenteric ganglionitis (in 1), and duplication of myenteric plexus with leiomyopathy (in 1). Desmosis was noted in all of them along with other primary pathologies. One of the IND patients also had visceral myopathy, type IV. Histopathologists need to follow a systematic approach comprising of diligent histological examination and use of immunohistochemistry, immunocytochemistry, and electron microscopy in CIP workup. Therapy and prognosis vary depending on lesions identified by pathologists. These lesions can be seen in isolation or in combinations.

Factors affecting quality of life in early childhood in patients with congenital hydrocephalus.

BACKGROUND: Predicting the outcome of congenital hydrocephalus in early infancy and childhood is difficult. Various consequences of hydrocephalus like ophthalmic, audiometric, musculoskeletal, and the developmental abnormalities play a complex role. We analyzed the quality of life of these patients in early life. METHODS: A prospective multispecialty assessment of the patients with congenital hydrocephalus, who had undergone ventriculoperitoneal shunt in the Pediatric Surgery unit of a tertiary care hospital, was carried out and analyzed. RESULTS: There were 24 boys and 6 girls. Eighty-three percent were operated before the age of 3 months. Mean age at follow up was 6 years (3-9 years). Shunt complications were seen in 53% (16) of the patients, out of which 68.75% had shunt blocks. In 70% (21) of the patients, the ventricle to hemisphere ratio (VHR) was between 51 and 70%, 20% (6) had a VHR of more than 70% and only 3 patients had a VHR between 40-50%. Audiological and ophthalmic problems were seen in 20 and 66% of the children, respectively. Musculoskeletal abnormalities were present in 36% of the patients. Developmental profile showed 44% being normal, 30% retarded, and 26% were borderline cases. The schooling had started in 56.6%, out of which only one child went to a special school. CONCLUSIONS: A multitude of problems associated with congenital hydrocephalus should be diligently diagnosed, aggressively followed and intervened with in the early years of life. Preschool management well before the peer interaction should optimize the social integration and improve the quality of life in these patients.

Quality of life of very young spina bifida patients after initial surgical treatment.

OBJECTIVE: The objectives of this study were to assess the quality of life (QOL) of operated patients with spina bifida (SB) in their initial years and to elucidate the factors affecting the QOL and the timing of proposed interventions. PATIENTS AND METHODS: We studied 18 patients operated on for SB, aging 3 years or more at the time of assessment. The quality of life score was calculated for all the patients by the parental-administered questionnaire method. The impact of all these factors on the social and school lives of these patients was studied. RESULTS: Eleven patients were having neurogenic bladder. Thirteen patients were having stool problems which ranged from mild to severe constipation and soiling. Five patients were having lower limb deformities interfering with normal ambulation. Ten patients were able to walk on their own without any help, four patients were using either crutches or help of the caregiver for ambulation while the remaining four patients were non-ambulatory. Twelve patients were attending school. The calculated QOL scores ranged from 2 to 15. The Barthel Index (BI) ranged from 15 to 100. The QOL questionnaire score and BI were showing significant positive correlation. CONCLUSIONS: The patients operated on for SB commonly have the neurological sequelae. The QOL score identifies the important problems in the initial years after surgery which can help in initiating and maintaining rehabilitative services in these patients. The treatment of urinary and fecal incontinence very early in life will allow these children to have a normal social and school life.

Esophageal atresia and tracheoesophageal fistula: Effect of pleural cover on anastomotic dehiscence.

BACKGROUND: A significant number of esophageal atresia and tracheoesophageal fistula patients have long gaps and a high propensity to leak. Anastomotic leak in esophageal atresia is associated with a significant morbidity and mortality. AIM: In a prospective randomized trial, we analyzed the risk factors leading to anastomotic dehiscence and studied the effect of pleural wrap as an additional vascular cover around the esophageal anastomosis. MATERIALS AND METHODS: Forty patients were divided into two groups A and B randomly. In 20 patients of group A, pleural wrap was utilized for covering the anastomosis and in 20 patients of group B, no such wrap was utilized. RESULTS: Both the groups were comparable regarding age, sex, weight, gap length, tension at anastomosis and the hospital stay. The overall leak rate was 25% (10/40) in both the groups. The leak rate was not significantly different in two groups whenever a gap length was less than 2 cm or more than 3 cm. However, for a gap length of 2-3 cm, the leak rate in group A was 18% (2/11) and in group B was 50% (4/8) (P = 0.05). Thirty percent (3/10) of patients, whose anastomosis was under tension, leaked in group A as compared to 75% (6/8) in group B patients (P = 0.001). CONCLUSIONS: Use of pleural wrap was associated with less anastomotic dehiscence in patients with moderate gap esophageal atresia (2-3 cm) especially when the anastomosis was under tension.

Covered exstrophy with anorectal malformation and vaginal duplication.

Covered exstrophy is a rare variant of the exstrophy-epispadias complex. We report a female newborn with covered exstrophy, absent anal opening and duplication of the introitus and the lower vagina. This rare, previously unreported, combination of anomalies highlights the complexity of the embryological events in the caudal area during separation of the hindgut and allantois.

Transanal Swenson's operation for recto-sigmoid Hirschsprung's disease.

BACKGROUND: Transanal Swenson's operation is a relatively new single-stage procedure for Hirschsprung's disease. The results of this procedure at our centre are presented. PATIENTS AND METHODS: Seventeen patients of recto-sigmoid Hirschsprung's disease underwent single-stage transanal Swenson's procedure. The diagnosis was based on the evidence of a transition zone on barium enema examination. A full thickness incision was made on the rectal wall posteriorly, 0.5 cm above the dentate line. The mobilised segment was resected about 5 cm above the transition zone. Frozen sections were performed whenever the transition zone was not clearly seen intra-operatively. The operation was completed by full thickness colo-anal anastomosis. RESULTS: There were fourteen male and three female patients. The ages of the patients ranged from two months to eight years (median 14 months). The median hospital stay was four days (range four to seven days). Two patients required additional abdominal mobilisation. The anatomical transition zone as seen intra-operatively correlated with the pathological transition zone in all the cases. Two patients had episodes of post-operative enterocolitis and the other two patients developed stricture of the anastomosis. The follow-up period ranged from six to 45 months (Mean 35.4 months). Post-operative soiling was observed in all the patients and lasted from two to six weeks (Mean 3.4 weeks). There were no injuries to the surrounding structures. No patient had voiding disturbances and post-void residual urine was normal in all the patients. Initial increased frequency of bowel movements had settled to one to three per day. CONCLUSIONS: Transanal Swenson's pull through not only avoids laparotomy, but also the problems associated with the muscular cuff of transanal endorectal pull-through. The anatomical transition zone can be safely utilised to decide the resection limits. By a meticulous technique of dissection, injury to the surrounding structures can also be avoided.
