The wandering ventriculoperitoneal shunt and the scope of its salvage

PURPOSE

Distal shunt tube migration following ventriculoperitoneal (VP) shunt placement in children is mostly managed by an initial shunt diversion/removal and subsequent replacement. Lately, shunt salvage is being used as an alternative in certain conditions. We have focused on the situations where one can consider or disregard shunt salvage in such cases.

METHOD

A retrospective study of children treated for distal shunt migration following VP shunt placement between January 2013 and December 2019.

RESULT

Seventeen children were managed for over 7 years. These included cutaneous extrusions (n = 4), hollow viscus perforation (n = 6), inguinal hernias (n = 5), and umbilical extrusion (n = 2). The surgical treatment varied from a cutaneous wound closure (with a tube in situ), temporary external shunt diversion, and laparotomy with shunt reposition into the peritoneal cavity. Shunt salvage was possible in three cases, whereas in 2 cases even though shunt salvage was possible, it was not feasible due to a short residual shunt length.

CONCLUSION

VP shunt salvage is possible in certain cases of distal shunt migration with a functional uninfected shunt. Small cutaneous extrusions can be covered by a local skin flap. Also, one should consider the residual intraperitoneal shunt length before its salvage in small children.

Isolated Penile Injury in Boys: Accident, Negligence, or Abuse?

Aim:

The aim of the study was to highlight the etiology, spectrum of presentation, and management of isolated penile trauma in boys.

Methods:

A retrospective review of boys treated for isolated penile trauma between January 2015 and June 2019 at a tertiary-level hospital.

Results:

Nine children were admitted over 4½ years. Etiology: The mechanism of penile injury (PI) was penile hair tourniquet (n = 5), postcircumcision (n = 2), dog bite (n = 1), and scald injury (n = 1). Extent of injury includes complete urethral transection at corona (n = 4); loss of urethral plate in a case of hypospadias (n = 1); complete loss of glans (n = 1); penile transection at corona (n = 1); total penile amputation (n = 1); and deep partial-thickness burns of penile shaft and adjacent suprapubic skin (n = 1). Management: One patient absconded. The remaining patients were managed as follows: calibration of urethral meatus (n = 1); penile burn was managed with dressing and antibiotics; coring of glans with urethral end–end anastomoses (n = 4); Bettocchi's quadrangular lower abdominal flap phalloplasty (n = 1); and Bracka's staged urethroplasty (n = 1). Complications include wound infection following trauma (n = 4), postsurgical infection (n = 3), urethrocutaneous fistula (n = 2), and reapplication of penile hair tourniquet (n = 1).

Conclusion:

Isolated PI in boys is not uncommon. Most are preventable if the parents are apprized and watchful. The clinician should also be vigilant regarding child maltreatment. A staged approach tailored to the type of injury provides a satisfactory outcome.

Bracka Urethroplasty with Buccal Mucosa Graft: Ergonomic Management of Penile Skin Dartos in the First Stage to Facilitate Second-stage Neourethral Coverage

Aims

The aim of the study was to report a new technique of ergonomic penile skin-dartos management during buccal mucosa graft (BMG) to provide adequate penile skin-dartos for neourethral coverage at the time of second-stage tubularization.

Materials and Methods

Ten proximal hypospadias with severe chordee underwent first-stage surgery with a new technique. An incision along the urethral plate margin and preputial edge was used to split inner prepuce off preputial dartos and penile degloving leaving inner prepuce attached to corona. Urethral plate was divided into the subfascial plane. Penile dartos was bisected in the dorsal midline. Distal half of penile skin-dartos bifurcated and joined to inner preputial edges. Mobilized and lateralized penile skin-dartos was sutured flanking edges of BMG. The second-stage tubularization after 6 months provided neourethral double dartos coverage with eccentric suture lines.

Results

Adequate dartos for neourethral coverage during second-stage tubularization was available in all. Subcoronal urethrocutaneous fistula occurred in one that was repaired.

Conclusions

Ergonomic management of inner-preputial skin and ventral transfer of penile skin-dartos helps in providing neourethral coverage during subsequent second-stage tubularization to minimize the occurrence of complications.

Evaluation of nebulized N-acetyl cysteine in outcome of esophageal atresia with tracheoesophegeal fistula

AIM

To evaluate the role of nebulized N-acetyl cysteine (NAC) in liquefying the airway secretions and improving the outcome of patients of esophageal atresia with tracheoesophageal fistula (EA + TEF).

METHODS

It was a non-randomized interventional study. Two milliliters of 10% NAC was given in a nebulized form (2:5 dilution, every six hourly) to patients of ET + TEF, along with regular suction of upper esophageal pouch. The group was compared with control, which comprised patients of EA + TEF receiving only saline nebulization. The consistency of the secretions was compared by hand held consistometer in unit of time (seconds) required to cross a predetermined distance along with gravity.

RESULTS

Sixty patients were assessed. Of these, 30 patients were present in both groups. The study group showed significant (p = 0.01-0.0001) decrease in consistency of secretions from the control group after day 2 of NAC nebulization. Patients' discharge was significantly (p = 0.01) earlier in cases. There was no significant (p = 0.41) difference in mortality between the groups. No specific adverse effects were observed in the study group.

CONCLUSION

It appears that nebulized NAC decreases the consistency of secretions in EA + TEF patients. It is interesting to note that the group of patients that received NAC was discharged earlier than the control group and had a higher survival rate than the control group. Whether this is directly attributable to the use of NAC is unknown. A prospective double-blinded randomized clinical trial is warranted to confirm these results.

LEVEL OF EVIDENCE

Level II, prospective comparative study (non-randomized).

Intussusception after Rotavirus Vaccine Introduction in India

BACKGROUND

A three-dose, oral rotavirus vaccine (Rotavac) was introduced in the universal immunization program in India in 2016. A prelicensure trial involving 6799 infants was not large enough to detect a small increased risk of intussusception. Postmarketing surveillance data would be useful in assessing whether the risk of intussusception would be similar to the risk seen with different rotavirus vaccines used in other countries.

METHODS

We conducted a multicenter, hospital-based, active surveillance study at 27 hospitals in India. Infants meeting the Brighton level 1 criteria of radiologic or surgical confirmation of intussusception were enrolled, and rotavirus vaccination was ascertained by means of vaccination records. The relative incidence (incidence during the risk window vs. all other times) of intussusception among infants 28 to 365 days of age within risk windows of 1 to 7 days, 8 to 21 days, and 1 to 21 days after vaccination was evaluated by means of a self-controlled case-series analysis. For a subgroup of patients, a matched case-control analysis was performed, with matching for age, sex, and location.

RESULTS

From April 2016 through June 2019, a total of 970 infants with intussusception were enrolled, and 589 infants who were 28 to 365 days of age were included in the self-controlled case-series analysis. The relative incidence of intussusception after the first dose was 0.83 (95% confidence interval [CI], 0.00 to 3.00) in the 1-to-7-day risk window and 0.35 (95% CI, 0.00 to 1.09) in the 8-to-21-day risk window. Similar results were observed after the second dose (relative incidence, 0.86 [95% CI, 0.20 to 2.15] and 1.23 [95% CI, 0.60 to 2.10] in the respective risk windows) and after the third dose (relative incidence, 1.65 [95% CI, 0.82 to 2.64] and 1.08 [95% CI, 0.69 to 1.73], respectively). No increase in intussusception risk was found in the case-control analysis.

CONCLUSIONS

The rotavirus vaccine produced in India that we evaluated was not associated with intussusception in Indian infants. (Funded by the Bill and Melinda Gates Foundation and others.).

Giant Occipital Encephalocele - Challenges in Management

Introduction

Giant occipital encephalocele (GOE) is a term used when the size of the OE is greater than or equal to the size of the head. It has been limited to case reports, with only sporadic exclusive series. This is a series of GOE managed at our center over time with emphasis on practical problems faced in management.

Materials and Methods

This was a retrospective observational study. The patients were evaluated for the age of presentation, sex, and head size. Any associated neural tube defect was also looked for. Imaging was used for associated brain anomalies and to plan the surgical procedure. The requirement of ventriculoperitoneal (VP) shunt was also assessed.

Results

During the study period of 7 years, 11 patients of GOE were admitted. Apart from one, all other patients were <1 year of age. Nine patients underwent surgical intervention, which included excision and repair of swelling with or without VP shunt placement. The content of the sac was only cerebrospinal fluid (CSF) in six patients and CSF and gliotic brain tissue in remaining patients. The attendants of two patients did not give consent for surgery and left against medical advice.

Conclusion

GOE is an uncommon entity with limited information about management. Careful evaluation, proper imaging of patient, and care during intraoperative and postoperative periods with emphasis of factors determining the prognosis may provide satisfactory results.

Meningocele tourniquet syndrome

Tourniquet syndrome is a rare condition where a tourniquet applied to an appendage leads to an obstructed blood flow and subsequent ischemic injury. Meningomyelocele and meningocele are common birth defects, and involvement of meningocele in tourniquet syndrome is never mentioned in the literature. We managed a 10-day-old male child presenting with infected lumber meningocele with a tourniquet tied at its base. It is being presented with review of relevant literature.

Intussusception in children aged under two years in India: Retrospective surveillance at nineteen tertiary care hospitals

Objective

Intussusception has been linked with rotavirus vaccine (RVV) as a rare adverse reaction. In view of limited background data on intussusception in India and in preparation for RVV introduction, a surveillance network was established to document the epidemiology of intussusception cases in Indian children.

Methods

Intussusception in children 2–23 months were documented at 19 nationally representative sentinel hospitals through a retrospective surveillance for 69 months (July 2010 to March 2016). For each case clinical, hospital course, treatment and outcome data were collected.

Results

Among the 1588 intussusception cases, 54.5% were from South India and 66.3% were boys. The median age was 8 months (IQR 6, 12) with 34.6% aged 2–6 months. Seasonal variation with higher cases were documented during March-June period. The most common symptoms and signs were vomiting (63.4%), bloody stool (49.1%), abdominal pain (46.9%) and excessive crying (42.8%). The classical triad (vomiting, abdominal pain, and blood in stools) was observed in 25.6% cases. 96.4% cases were diagnosed by ultrasound with ileocolic location as the commonest (85.3%). Management was done by reduction (50.8%) and surgery (41.1%) and only 1% of the patients’ died. 91.1% cases met Brighton criteria level 1 and 3.3% Level 2. Between 2010 and 2015, the case load and case ratio increased across all regions.

Conclusion

Intussusception cases have occurred in children across all parts of the country, with low case fatality in the settings studied. The progressive rise cases could indicate an increasing awareness and availability of diagnostic facilities.

Role of Bishop–Koop Procedure for Jejunal and Proximal Ileal Atresia

Background: This study was undertaken to review the Bishop–Koop procedure as a treatment option with a grossly dilated proximal segment in jejunal and proximal ileal atresia.Materials and Methods: This was a retrospective cohort study conducted from January 2012 to June 2018 in the Department of Pediatric Surgery at King George's Medical University, Lucknow, India. The outcome, complication rate, and the follow-up study for postoperative adverse outcomes were assessed.Results: Thirty-two neonates underwent Bishop–Koop procedure. The mean age at presentation was 4.37  2.3 days. The male (n=22) to female (n=10) ratio was 2.2:1. Sixteeen had jejunal (type II-9, type III- 7), and 16 (type II-6, type III-10) had proximal ileal atresia. The mean duration of the hospital stay was 13.03  5.7 days. Oral feeds were initiated by the 7th postoperative day. In our study, the complication rate was 31.25% (n=10) and mortality rate was 37.5% (n=12).Conclusions: Bishop–Koop procedure appears to be a technically efficient method in desperate cases of jejunoileal atresia with a grossly dilated proximal segment, although more extensive studies may be needed to compare Bishop–Koop procedure and other operation techniques.

Evaluation of Effect of Propranolol on Serum Vascular Endothelial Growth Factor and Tissue Inhibitor of Metalloproteinase-2 Levels in Infantile Hemangioma

Background:

Infantile hemangioma is the most common tumor of infancy. Currently, propranolol is a preferred drug for treating hemangioma. The exact mechanism of action of propranolol is not known. In this study, we attempted to assess whether propranolol has any effect on vascular endothelial growth factor (VEGF) and tissue inhibitor of metalloproteinase-2 (TIMP-2) over a period of time, and if it is there, how long it affects it.

Materials and Methods:

Propranolol was administered in the dosage of 2–3 mg/kg. The first serum sample was collected before starting the propranolol treatment. Thereafter, samples were collected at monthly intervals up to a total of six samples. The samples were assessed for TIMP-2 and VEGF using enzyme-linked immunosorbent assay kit.

Results:

The duration of this study was from June 2016 to November 2017. The total number of patients in this study was 15. Thirteen patients responded to treatment. The mean age of patients was 7.1 months. The mean value of baseline VEGF was 0.234 ± 0.059 and that of TIMP-2 was 1.338 ± 0.679. As compared to baseline value, the P value was statistically not significant in any of sequential values. In category-wise analysis, apart from statistically significant value in the 6^th month in excellent category and good response category in the 1^st month, all other values did not reveal any significant change in VEGF analysis. The analysis of TIMP-2 revealed a significant change in the levels from Sample 2 to Sample 6 in the excellent response group; however, the levels did not show a specific trend either increasing or decreasing.

Conclusion:

Despite its beneficial action in regression of hemangioma, the exact mechanism is yet to be identified. The exact duration of treatment needs further evaluation.

Management Strategy of Meconium Ileus-Outcome Analysis

Background:

Meconium ileus (MI) is defined as an intestinal obstruction caused by the impaction of inspissated meconium in the terminal ileum. In this study, we have evaluated the nonoperative management of patients of simple MI without fluoroscopic support –an important requisite of the Noblett's criteria. Besides this, surgical management in cases of failed conservative management and complicated MI was also assessed.

Materials and Methods:

This was a retrospective observational study. Various clinical and radiological parameters were evaluated. Conservative management included the use of water-soluble contrast diatrizoate meglumine and diatrizoate sodium. In case of nonpassage of meconium in 24 h from first intervention, exploratory laparotomy with ileostomy was performed. All complicated MI underwent exploratory laparotomy with creation of stoma as and when needed.

Results:

The duration of this study was 6½ years. Twenty-five neonates of MI were admitted. Of these, 22 had simple MI and remaining three had complicated MI. Eighteen neonates responded to the conservative management. In four neonates, who did not respond, exploratory laparotomy was performed. All three neonates having complicated MI underwent exploratory laparotomy. One patient expired in follow-up.

Conclusion:

MI is an important neonatal emergency, which needed immediate attention of a pediatric surgeon. Proper evaluation of the patient, careful application of principals of conservative management, and timely surgical intervention may fetch satisfactory results.

Evaluation of Clinical and Radiological Factors Determining the Need of Post-operative Ventilator Requirement in Patients of Esophageal Atresia

Objective: Ventilator requirement is an important constituent of post-operative care of patients of esophageal atresia (EA). In contrast to the developed world, the situation is very different in developing countries where the resources are limited, and ventilator may not be available to all patients of EA. This study was conducted to assess whether there are certain criteria, which may predict the possibility of non- requirement of ventilator for patients of EA in the post-operative period. Design: This study was a retrospective observational study. Setting: This study was conducted at a tertiary care teaching hospital. Duration: This study was conducted from 5 years and 6 months. Materials and Methods: We used certain parameters to assess the requirement of ventilators for the patients in the post-operative period. These included the presentation of patients before or after 3 days of life and birth weight (BW) of more or <2.5 kg. Presence of respiratory distress (RD) was analyzed. The presence of consolidation on X-ray was also evaluated. Results: The total number of patients was 175. In univariate analysis, the need of ventilator was significantly higher in patients presenting after 3 days of life, weight <2.5 kg, presence of RD, and pneumatic patch. In multivariate analysis, the age of presentation, weight, RD, and consolidation were found to independent factor for the ventilator requirement. Conclusion: On the basis of clinical and radiological features, namely, age, sex, BW, RD, and consolidation, we may prioritize these patients of EA, who may not be requiring the ventilator in the post-operative period. Further prospective studies on the basis of these factors may substantiate our efforts.

Atresia of the Colon: Etiological Aberrations, Clinical Observations, and Challenges in Management

Objective: The objective of this study is to review the clinicoradiological profile, scheme of management and the outcome in cases of colonic atresia (CA), and ascertain an optimal approach for the treatment of CA to minimize morbidity and mortality. Design and Setting: This was a retrospective observational study carried out at a tertiary health‑care center. Duration: Total of 6 years duration (January 2011–December 2016).Materials and Methods: A retrospective analysis of 10 patients of CA managed over a 6- year period. Data related to demographics, clinical presentation, associated anomalies, radiologic, intraoperative findings, postoperative stay, complications, and outcome were analyzed.Results: There were three cases of Type II atresia involving terminal ileum, cecum, and adjacent colon. Three cases had proximal ascending colon atresia (Type IIIa [n = 2]; Type I [n = 1]) Type I [n=1], and two cases of type IIIa atresia of the hepatic flexure. Two babies had atresia involving the sigmoid colon; one had Type II atresia, while we were unable to assign a type to the other within the prevailing classification. Seven babies were initially treated with a stoma either in the ileum (n = 3), hepatic flexure (n = 2), and sigmoid colon (n = 2), whereas three were treated with a primary anastomoses. Cases treated with a primary anastomoses had lesser morbidity and a better outcome than those with an ileal or ascending colon stoma.Conclusion: Contrary to the theory of an acute antenatal vascular accident, CA may rarely result from a gradual, sequential obliteration of mesenteric vasculature. Primary anastomosis should be contemplated in proximal CA wherever possible as stomal complications, especially high stoma output can result in considerable morbidity.

IschioPubic Osteotomy, A Simple and Effective Technique for Pelvic Ring Closure in Repair of Classic Exstrophy Bladder

AIM

The aim of this study is to report the technique and outcome of ischiopubic (IP) osteotomy for pelvic ring closure in classic exstrophy bladder.

METHODS

A total of 85 male classic exstrophies were selected based on trapezoid-shaped space between IP ramus on three-dimensional computed tomography pelvis. Using midline scroto-perineal approach, after bladder plate mobilization and radical corporal detachment; the pelvic surface of superior pubic ramus (SPR) was exposed. Above the obturator canal, H-shaped incision was made on periosteum of the SPR. The horizontal line of H was placed above the obturator canal. Rectangular periosteal flaps above and below the horizontal line was raised. In the subperiosteal plane, curved hemostats encircled the SPR that were divided using a bone drill. On the medial aspect of ischial tuberosity, a notch was created as hinge using a bone drill. Forks of bone holding forceps hooked the pubic bone and tightened for its midline approximation, lengthening of the SPR and inward rotation of IP ramus. Linea alba and pubic bones were approximated with interrupted Polygalactin sutures.

RESULTS

Midline approximation of pubic bone and linea alba was possible in all. There was no injury to obturator nerve, vessels, or other structures .

CONCLUSIONS

IP osteotomy is the safe and effective technique of pelvic ring closure in patients with specific pelvic configuration.

Ectopic Salivary Gland Cyst in the Neck: Association with Congenital Plunging Ranula

Congenital ranula is rare. We report a large, symptomatic, congenital plunging ranula associated with a salivary gland cyst in the neck. To the best of our knowledge, this is the first such reported case. Even though both the cysts had their origin from the sublingual gland, only the cervical cyst had a capsular covering. Herniation of a part of the immature sublingual gland anlage through a congenital mylohyoid defect, its separation, and subsequent maturation could explain this occurrence.

Undescended testicle: An update on fertility in cryptorchid men

Cryptorchidism or undescended testis is one of the most common anomalies encountered in paediatric urology and is estimated to affect 1 to 4 per cent of full term and upto 30 per cent of preterm male neonates. The associated problems of sub-fertility or infertility and malignant transformation have been recognized for long. Fertility is impaired after both unilateral and bilateral cryptorchidism. The reported paternity rates in adults are about two-third for unilateral undescended testis and less than one-third for bilateral disease. Over the last five decades, the concepts related to cryptorchidism have changed dramatically as knowledge about its effects has accrued from research conducted worldwide. The recommended age of orchidopexy has fallen progressively from adolescence to less than one year. The realization that the infantile testes are not in a state of ‘suspended animation’ and the recognition of the defect in the androgen dependent transformation of gonocytes into adult dark spermatogonia in cryptorchidism have been recognized as the primary cause of sub-fertility in these patients. This has paved the way for hormone therapy in an attempt to simulate the ‘post-natal gonadotropin surge’ or ‘mini-puberty’. This review summarizes the current knowledge about the various factors affecting the fertility status in cryptorchidism with a particular focus on the derangements in the development and maturation of the germ cells and the role of surgery, hormone therapy and antioxidants in reversing these changes.

Bladder exstrophy: Comparison of anatomical bladder neck repair with innervation preserving sphincteroplasty versus Young-Dees-Leadbetter bladder neck reconstruction

Aim:

To evaluate the outcome of innervation preserving sphincteroplasty along with anatomical bladder neck reconstruction (IPS-ABNR) compared to classic Young-Dees-Leadbetter (YDL) bladder neck reconstruction in exstrophy with insufficient bladder capacity requiring detubularized-ileocystoplasty.

Materials and Methods:

Sixteen male patients of exstrophy bladder who required ileocystoplasty from 2004 to 2010 were randomized into group A (n = 7) and group B (n = 9). After detubularized-ileocystoplasty with Mitrofanoff stoma and ureteric reimplantation in all, group A received YDL bladder neck repair while group B received IPS-ABNR repair through a midline scrotoperineal approach. Outcome measurement included operative and postoperative problems, continence, and upper tract status.

Results:

In group A, two had incompetent bladder neck with gross incontinence, while four had a dry interval of more than 3 h without the ability of voiding per urethra. In group B, seven patients had dry interval of more than 3 h with an ability of urethral voiding and midstream holding in five.

Conclusions:

Exstrophy patients requiring augmentation cystoplasty and repaired with IPS-ABNR can achieve dynamic bladder outlet resistance with adequate leak point pressure and ability to void voluntarily with midstream holding capability. The children had the satisfaction of voiding per urethra with ability to stop in midstream similar to that in normal children.

Congenital lumbar hernia: 20 years' single centre experience

AIM

Congenital lumbar hernia is an uncommon anomaly with only few cases reported in the English literature. This study was done to study the incidence, associated conditions, management and complications of congenital lumbar hernia repair in paediatric patients.

METHODS

Retrospective study of all patients over a period of 20 years (January 1990 to January 2010) was analysed.

RESULTS

A total of 18 patients (two bilateral hernias) were encountered in this series. All were in the age group of 1 day to 6 years. All the patients were operated by open technique. Primary repair was done in 14 patients and prosthetic meshplasty in two. Two patients could not be operated. The average follow-up period was 3 years. There was no follow-up loss in our study. There was no evidence of recurrence in this series.

CONCLUSION

Up until now, the total number of cases is 68. The large size of hernia defect (>10 cm) may determine the use of prosthetic mesh repair. Proper surgical treatment, either primary repair or hernioplasty, provides adequate management of this condition.

Chronic cervical lymphadenopathy in children: Role of ultrasonography

Aim:

To assess the usefulness of ultrasonography in the differentiation of causes of chronic cervical lymphadenopathy in children.

Materials and Methods:

Children with palpable cervical lymph nodes were included. An ultrasonographic examination was performed to delineate multiple lymph nodes, irregular margins, tendency towards fusion, internal echos, the presence of strong echoes and echogenic thin layer.

Results:

The total number of patients was 120. Echogenic thin layer and strong internal echoes were specific for tuberculosis. Long axis to short axis (L/S) ratio was more than 2 in most of the tubercular nodes (85.71%). Hilus was present in 50 (73.53%) tubercular lymphadenitis, 12 (40%) lymphoma and 10 (62.5%) cases with metastatic lymph nodes. Hypoechoic center was present in 60 (88.24%) tubercular lymphadenitis cases followed by 62.5% metastatic and 60% malignant lymphoma cases.

Conclusions:

Ultrasonography is a non-invasive tool for lymph nodal evaluation in children. It may be used to differentiate cervical lymphadenopathy with different etiologies in children. When correlated clinically, it may avoid biopsy in a patient.

Esophageal Anastomosis Medial to Preserved Azygos Vein in Esophageal Atresia with Tracheoesophageal Fistula: Restoration of Normal Mediastinal Anatomy

Objective: We intended to prospectively study the technical feasibility and advantages of esophageal anastomosis medial to the preserved azygos vein in neonates diagnosed with esophageal atresia with tracheoesophageal fistula (EA/TEF). The results were compared to the cases where azygos vein was either not preserved, or the anastomosis was done lateral to the arch of preserved azygos vein. Material and methods: A total of 134 patients with EA/TEF were admitted between January 2007 and July 2008 of which 116 underwent primary repair. Eleven patients with long gap esophageal atresia with or without tracheoesophageal fistula and 7 patients who expired before surgery were excluded. Patients were randomly divided in three groups comparable with respect to the gestational age, age at presentation, sex, birth weight, associated anomalies and the gap between the pouches after mobilization: Group A (azygos vein ligated and divided), Group B (azygos vein preserved with esophageal anastomosis lateral to the vein), and Group C azygos vein preserved with esophageal anastomosis medial to the vein). All the patients were operated by extra-pleural approach. The three groups were compared with respect to operative time and early postoperative complications like pneumonitis, anastomotic leaks and mortality. Odds ratio and Chi square test were used for the statistical analysis. Results: Group A, B and C had 35, 43 and 38 patients respectively. No significant difference was observed in average operative time in the 3 groups. Though incidence of postoperative pneumonitis was higher in group A (28%) as compared to group B (13.95%) and group C (11.62%), it was not statistically significant (p > 0.005). Anastomotic leak occurred in 7 patients in group A (20%), 6 patients in group B (13.95%) and 4 patients (10.52%) in group C (p > 0.005). Group A had 3 major and 4 minor anastomotic leaks; group B had 2 major and 4 minor leaks and group C had 1 major and 3 minor leaks. There were10 deaths in the series- 5 in group A, 3 in group B and 2 in group C (p > 0.005). Patients with major anastomotic leaks in all 3 groups expired after re-exploration. The minor leaks were managed conservatively and all of them healed spontaneously. Severe pneumonitis and septicemia in patients having major associated anomalies also contributed to the mortality.Conclusions: Although esophageal anastomosis medial to the preserved azygos vein restores the normal mediastinal anatomy without technical difficulty or increased operative time, the study could not prove a statistically significant advantage in terms of mortality and postoperative complications.

Esophageal atresia associated with anorectal malformation: Is the outcome better after surgery in two stages in a limited resources scenario?

Aims:

To analyze whether outcome of neonates having esophageal atresia with or without tracheoesophageal fistula (EA±TEF) associated with anorectal malformation (ARM) can be improved by doing surgery in 2 stages.

Materials and Methods:

A prospective study of neonates having both EA±TEF and ARM from 2004 to 2011. The patients with favorable parameters were operated in a single stage, whereas others underwent first-stage decompression surgery for ARM. Thereafter, once septicemia was under control and ventilator care available, second-stage surgery for EA±TEF was performed.

Results:

Total 70 neonates (single stage = 20, 2 stages = 30, expired after colostomy = 9, only EA±TEF repair needed = 11) were enrolled. The admission rate for this association was 1 per 290. Forty-one percent (24/70) neonates had VACTERL association and 8.6% (6/70) neonates had multiple gastrointestinal atresias. Sepsis screen was positive in 71.4% (50/70). The survival was 45% (9/20) in neonates operated in a single stage and 53.3% (16/30) when operated in 2 stages (P = 0.04). Data analysis of 50 patients revealed that the survived neonates had significantly better birth weight, better gestational age, negative sepsis screen, no cardiac diseases, no pneumonia, and 2-stage surgery (P value 0.002, 0.003, 0.02, 0.02, 0.04, and 0.04, respectively). The day of presentation and abdominal distension had no significant effect (P value 0.06 and 0.06, respectively). This was further supported by stepwise logistic regression analysis.

Conclusions:

In a limited resources scenario, the survival rate of babies with this association can be improved by treating ARM first and then for EA±TEF in second stage, once mechanical ventilator care became available and sepsis was under control.

Retrospective analysis of paediatric achalasia in India: single centre experience

BACKGROUND

Developing countries at tertiary referral centre. The aim of this study was to share our experience of paediatric achalasia in Indian scenario.

MATERIALS AND METHODS

This was a retrospective analysis of children <16 years, operated for achalasia at our centre, from December 1998 to December 2011.

RESULTS

Total 40 patients (mean age 39 ± 4.29 months), including 1 patient of megaesophagus were operated over 13 years of period; 17 patients (associated congenital H-type tracheoesophageal fistula in one patient, non- responders/ lost follow-up for minimum of 3 years in 16 patients) were excluded from the study. The response rate of parents in follow-up was 60.0%. Mean symptoms duration was 27.88 ± 2 months. Most common symptoms were regurgitation and failure to thrive (78.2%). Mean symptom scoring in follow-up after 3 year was 1 ± 0.7 compared to 5 ± 0.51 at the time of admission (P < 0.012). One infant expired (mediastenitis), one developed adhesive intestinal obstruction and one needed posterior re-myotomy (for megaesophagus). There were no treatment failures in mean follow-up of 40.2 ± 5.07 months.

CONCLUSIONS

Cardiomyotomy with partial fundoplication is the best modality of treatment for paediatric achalasia cardia, even from parents' perspective.

Six-year retrospective analysis of colonic perforation in neonates and infants: single centre experience

BACKGROUND

Developing countries at tertiary referral centre. This study analysed the aetiology of colonic perforation (CP) in neonates and infants.

MATERIALS AND METHODS

Retrospective analyses of 60 CP cases (presented from May 2005 to May 2011) were done.

RESULTS

The mean age at presentation was 8.33 ± 0.11 days (range, 2-110 days). The aetiology were Hirschsprung's disease (HD), necrotising enterocolitis (NEC) and idiopathic perforation in 78.33% (47/60), 6.67% (4/60) and 15% (9/60), respectively. There were 210 patients with histopathologically proven HD; 22.38% (47/210) cases of HD had CP. Most common site of perforation was mid-transverse colon (74%, 35/47) in HD patients. All HD-associated mid-transverse colonic, caecal, appendicular and ascending colon perforations (except one caecal perforation) had aganglionic recto-sigmoid region and ganglionic perforation site. Features of enterocolitis were not found in any HD patients. Two patients (3.33%) died due to sepsis.

CONCLUSIONS

There was a high rate of primary HD-associated colonic perforation in this study. Colonic perforation may the initial presenting condition in HD disease. We advocate colonic biopsy to rule out HD in any neonate presenting with primary colonic perforation.

A newer variant of congenital pouch colon with rectal agenesis: management strategy and review of the literature

A 3-day-old male baby presented with clinico-radiological features of rectal atresia with colo-urinary fistula. There was no radiological evidence of congenital pouch colon (CPC), but per-operatively CPC of unusual anatomy was found. The CPC was intermediate between type I and type II of Narsimha's classification. The pouch had rudimentary appendix and proximal colovesical fistula. The distal end of CPC was free. In the first stage, diverting ileostomy was done. In follow-up, after 1 month because of rectourinary fistula baby developed hyperchloremic metabolic acidosis and uremic sepsis. First metabolic correction and control of sepsis were done. Thereafter, abdomino-posterior saggital approach was used for excision of colovesical fistula, appendectomy, coloplasty and colorectal anastmosis. The ileostomy was left undisturbed. The infant at present is waiting for the third stage ileostomy closure.

Delayed presentation of anorectal malformations

Aims and Objectives:

Delayed management of anorectal malformation (ARM) increases the surgical and functional complications for the patient. We defined “delayed presentation of ARM” and reviewed our patients with ARM to find out the incidence and causes of delayed presentation.

Materials and Methods:

Patients satisfying the criteria of “delayed presentation of ARM” were involved. Detailed information of each patient including the mode of presentation, associated anomalies, plan of management and follow-up was obtained from the hospital records.

Results:

Between 2003 and 2006, 43 patients satisfied our criteria of “delayed presentation of ARM”. There were 21 males and 22 females. Seventeen of these males presented with low-type ARM. Eleven of them were managed by a single-stage procedure. These “delayed presenters” had to live with constipation, inadequate weight gain and parental anxiety for a greater time. Analysis of the outcomes showed more functional complications in patients who had undergone failed perineal surgery previously. In females with low ARM, the procedure of choice was anterior sagittal anorectoplasty (ASARP). Single stage surgery provides good outcomes for most of low type of ARMs. High-type ARMs in males and females were managed by a staged procedure.

Conclusion:

“Delayed presentation of ARM” is a major group of ARM in our setup. The management and results of their treatment are not different from those of the early presenters. The most common cause of delayed ARM is wrong advice given by the health care providers followed by inadequate treatment elsewhere. Corrective surgeries taking second attempt in perineum always produces poor outcomes.

Vaginal agenesis: Experience with sigmoid colon neovaginoplasty

Aim:

Objective of this study is to report our experience with sigmoid vaginoplasty in adolescents.

Materials and Methods:

A retrospective study of children with vaginal atresia and Mayer–Rokitansky–Kuster–Hauser syndrome. The sigmoid segment was used for vaginoplasty in all the cases.

Results:

Eight children were studied over a period of 7 years. The postoperative complications were ileus in 2, mucosal prolapse of the neovagina in 1, and minor wound infection in 1 patient. Seven patients are on regular follow-up. All the neovaginas were patent and functional. One patient had unacceptable perineal appearance, that is, badly scarred perineum as a late complication. None of the patients had vaginal stenosis or excessive mucus discharge, during follow-up visits. Out of the 7 patients, 2 patients are sexually active and satisfied.

Conclusions:

Sigmoid vaginoplasty is a safe and acceptable procedure for vaginal agenesis with good cosmetic results and acceptable complications rate. Sigmoid colon vaginoplasty is the treatment of choice because of its large lumen, thick walls resistant to trauma, adequate secretion allowing lubrication, not necessitating prolonged dilatation, and short recovery time.

Laparoscopic surgery in a paediatric patient with Down's syndrome and patent foramen ovale

The safety of laparoscopic surgery in infants with congenital heart disease has been a subject of controversy despite potential benefits over open surgery. The authors present the anaesthetic management of a 6-month-old female infant with Down's syndrome with a small patent foramen ovale with left to right shunt who successfully underwent laparoscopic coloplasty. There were no intraoperative or postoperative complications. In addition to the routine anaesthetic considerations for any surgical patient, the choice of the anaesthetic technique in patients undergoing laparoscopic procedures should consider the effect on the patient's underlying cardiorespiratory function of pneumoperitoneum and carbon dioxide insufflation.

Complicated Rapunzel syndrome mimicking intussusception

A 5-year-old girl presented with a 3-day history of pain and distension of abdomen, bilious vomiting, bleeding per rectum and a hard lump in the left iliac fossa. Intussusception was clinically diagnosed. On exploratory laparotomy, trichobezoar showing cast of the stomach, duodenal C-loop and tail were extracted. The stomach cast was impacted at the distal ileum, while its tail traversed the ileum, ileocecal valve and extended up to the hepatic flexor. At the site of impaction, a large ileal perforation, covered by bezoar was present. Hence, x-ray did not reveal pneumoperitoneum. There was no evidence of trichobezoar in the stomach. Perforation was exteriorised as loop ileostomy. She was of normal intelligence. Psychological evaluation of the child was performed and a behaviour therapy was advocated. Ileostomy closure was done after 2 months. At 6 months follow-up, no recurrence was found.

Simultaneous occurrence of jejuno-jejunal and ileo-ileal intussusception in a child: a rare occurrence

Intussusception is the most common cause of intestinal obstruction in infants and children. This condition is frequent in children and presents with the classic triad of cramping abdominal pain, bloody diarrhoea and a palpable tender mass. Small bowel intussusceptions are much less common, with jejuno-ileal and duodeno-jejunal intussusceptions being the rarest types of all. Multiple simultaneous intussusception is a peculiar variety of intussusception. The authors report the simultaneous occurrence of jejuno-jejunal and ileo-ileal intussusception in a patient. As this is an extremely uncommon entity, it is being reported with a brief review of the relevant literature.

Modified method of T-tube placement in cases of ruptured choledochal cyst having complete loss of anterior wall

Survival rates for infants and children who have choledochal cyst with or without spontaneous rupture have improved dramatically in the past decades. Despite excellent long-term survival for patients with choledochal cyst who undergo elective surgery, many significant complications can occur in the patients being operated in emergency for rupture of the cyst. Spontaneous rupture of the cyst is one such problem resulting in considerable morbidity and mortality in these patients. Majority of surgeons manage these cases with T-tube external drainage. The conventional methods of T-tube placement for long period has remained simple as described in choledochotomies where there is no deficit of the walls of common bile duct (CBD). The present technique has been designed specially for the cases of ruptured choledochal cyst, where the wall of the CBD gets necrosed leaving behind a long gap between the two ends. In these cases, placement of T-tube with conventional method is not possible because there is no wall to suture together, and make the CBD water tight again to prevent leakage of bile. We found only two patients of spontaneous rupture of choledochal cyst with a long gap between two ends of CBD because of necrosed anterior wall. In both of these patients, it was not possible to put T-tube with traditional method and one would have to opt for primary definitive repair despite poor general condition of patients.

Neonatal pneumoperitoneum: a critical appraisal of its causes and subsequent management from a developing country

BACKGROUND

The diagnosis and management of neonatal pneumoperitoneum revolves around necrotizing enterocolitis (NEC) in most of the published literature. Although NEC remains the major cause of pneumoperitoneum in a neonate, there are several other causes leading to free air in the peritoneal cavity. A number of case reports have appeared describing pneumoperitoneum in a newborn due to rupture of one particular organ, but there have been only few collective reviews on the subject. The present study shares the experience with neonates admitted with a diagnosis of pneumoperitoneum in a pediatric surgical center of a developing country. The various causes of pneumoperitoneum in a newborn, their management and subsequent outcome are described.

MATERIALS AND METHODS

The study was conducted in the Department of Pediatric Surgery, CSMMU (upgraded King Georges Medical College), Lucknow, India. All the neonates admitted with a diagnosis of pneumoperitoneum during the period of last 3 years (2005-2008) were retrospectively analyzed. Other neonatal admissions were also retrieved for the same period. Free air was confirmed by erect abdominal X-ray or lateral decubitus films in certain cases. The data sheets were analyzed regarding age of presentation, cause of bowel perforation, management offered and subsequent outcome achieved. All patients of NEC without evidence of perforation were not included in the study (n = 21).

RESULTS

Out of total 537 neonatal admissions, 89 (16.5%) neonates were admitted with a diagnosis of pneumoperitoneum. There were 79 (88.7%) males and only 10 (11.6%) female neonates admitted during the study period. All of them had evidence of pneumoperitoneum at the time of admission. The age at presentation ranged from 4 to 32 days. NEC remained the single major cause of pneumoperitoneum in the newborn; however, in 44 (49.4%) patients the cause was not related to NEC. Perforated pouch colon, isolated colonic perforations, caecal perforations, gastric and duodenal perforations were the main causes of pneumoperitoneum not related to NEC. There were seven patients in whom no cause of pneumoperitoneum could be ascertained. The treatment was individualized according to the presentation. Most of the NEC-related perforations were managed by peritoneal drains. Laparotomy was done in rest of the patients. Three patients were managed conservatively. Overall, 19 (21.6%) patients expired. Most of those expired were of low birth weight with NEC and congenital pouch colon with perforation.

CONCLUSION

Neonatal pneumoperitoneum remains a surgical emergency and outcome can be lethal if the problem is not addressed early. NEC remains the major cause; however, there are several other important causes of isolated gastrointestinal perforations leading to neonatal pneumoperitoneum. The management should be individualized in these patients and the outcome largely depends on the early recognition of the condition.

Long-term results of anterior sagittal anorectoplasty for the treatment of vestibular fistula

PURPOSE

Vestibular fistula is the commonest anorectal malformation in the female child. This article reports the treatment and long-term follow-up of 1206 patients of vestibular fistula treated by anterior sagittal anorectoplasty (ASARP) in a single center for 38 years.

MATERIAL AND METHODS

All patients of vestibular fistula admitted and operated on at the Department of Pediatric Surgery, King George Medical University (Lucknow, UP India), from 1970 were included in the study; the age ranged from 2 days to 40 years. The diagnosis was made by clinical examination. We differentiated between anovestibular fistula (AVF) and rectovestibular fistula (RVF) in that the latter is a longer narrow fistula closely applied to the posterior wall of the vagina. Preoperative investigations included hemogram and blood glucose. Echocardiography was done in those patients showing a physical sign of cardiac anomaly. All patients were operated on in the lithotomy position by ASARP; this was done without colostomy in 1169 patients. In 6 patients, preliminary colostomy was done because of excessive perineal excoriation, and 31 others had colostomy done elsewhere. The striated muscle complex was delineated by electrostimulation, and anoplasty was performed after anchoring the rectum within the muscle complex. Washing of the perineum after passage of stools with application of povidone-iodine ointment constituted the local care. Intravenous antibiotics were administered for 48 hours and oral antibiotics (including metronidazole) for 5 days. The patient was discharged home by the fifth day.

RESULTS

Follow-up ranges from 3 months to 19 years; uneventful postoperative recovery was seen in 1147 patients. They had normal growth and development, normal appearance of the perineum, and a normal quality of life. Complications were seen in 60 patients (5%) of which 42 had AVF and 18 had RVF. Eight patients had postoperative wound disruption that was minor in 4 and required colostomy in the other 4. Four patients had recurrence of vestibular fistula thus creating an iatrogenic perineal canal; this could be repaired by a second ASARP in 3 patients and required colostomy and PSARP in one child. Anal stenosis was seen in 11 patients; this was treated by dilatation alone in 6 and required posterior Y-V plasty in 5. The rate of complications in RVF was lower than AVF probably because of lesser number of patients; there was no difference in stooling pattern or continence between uncomplicated patient of RVF and AVF; however, fecal staining was seen in all patients undergoing revision surgery for complications.

CONCLUSIONS

This experience with ASARP showed a good result in 95% patients in a single-stage procedure. The technical ease and minimal preoperative and postoperative measures make ASARP the procedure of choice for vestibular fistula in females at all ages. Until sufficient experience is gained, it may be safer to operate on patients with RVF under cover of a protective colostomy.

Modified method of primary esophageal anastomosis with improved outcome in cases of esophageal atresia with tracheoesophageal fistula

Survival rates for infants who have esophageal atresia (EA) with or without fistula (TEF) have improved dramatically in the past 50 years. Despite excellent long-term survival for patients with esophageal atresia with tracheoesophageal fistula (EA-TEF), many significant complications can occur. Anastomotic leak at the esophagoesophagostomy site is one such problem resulting in considerable morbidity and mortality in these patients. The methods of esophageal anastomosis for long period has remained the simple end to end anastomosis of esophageal ends with various modifications described from time to time. The present study aims to study the effect on the early postoperative complications, following horizontal mattress suture technique on the primary esophageal anastomosis in cases of EA-TEF. A total of 32 patients with EA-TEF, were operated by our technique during a period of 1 year (2007-2008). The results were compared with the patients (n = 66), who were operated by the traditional simple technique during the same period. Among those patients in whom the esophageal anastomosis was done by horizontal mattress suture, only one had major anastomotic leak, while two had minor anastomotic leaks, as compared to six and nine cases correspondingly in other patients in whom anastomosis was done by simple technique. There was single mortality. We propose that, the utilization of our technique of horizontal mattress suture in primary anastomosis of esophagus in cases of EA-TEF significantly reduces the risk of anastomotic leaks and subsequent morbidity and mortality.

Four-country surveillance of intestinal intussusception and diarrhoea in children

AIM

Establishment of baseline epidemiology of intussusception in developing countries has become a necessity with the possibility of reintroduction of rotavirus vaccine. The current study assessed the seasonal trend in cases admitted with intussusceptions and dehydrating acute watery diarrhoea in children aged 2 months to 10 years.

METHODS

In a prospective surveillance study, teaching and research hospital sites in India (Lucknow and Nagpur), Brazil (Fortazela), Egypt (Ismailia) and Kenya (Nairobi) established a surveillance where a network of hospitals with surgical facilities catered to a reference population of about 1-2 million for reporting of intussusception. One large hospital per site also recruited admitted cases of acute watery diarrhoea.

RESULTS

From April 2004 to March 2006, 173 and 2346 cases of intussusception and diarrhoea, respectively, were recruited. Cases of intussusception had no apparent seasonality. Most cases of intussusception (61.3%) (107/173) were in the < or =1 year age group, with males comprising 68.8% (119/173) of all cases. Hospital mortality of intussusception was 4.2% (4/96). Cases of diarrhoea peaked in March, with 56.6% (1328/2346) of admitted cases being males. Majority (83.1%) of cases of diarrhoea had received antibiotics, and the hospital mortality was 0.8% (18/2280).

CONCLUSION

Intussusception in the four participating countries exhibited no seasonal trend. We found that it is feasible to establish a surveillance network for intussusception in developing countries. Future efforts must define population base before the introduction of rotavirus vaccine and continue for some years thereafter.

Genetic analysis of the SRD5A2 gene in Indian patients with 5alpha-reductase deficiency

BACKGROUND

5alpha-Reductase deficiency (5RD) is an uncommon autosomal recessive disorder of sexual differentiation. It results from impaired conversion of testosterone to dihydrotestosterone due to mutations in the steroid 5alpha-reductase type 2 gene (SRD5A2). Mutations in SRD5A2 have not been previously reported in Indian patients with 5RD.

AIM

To delineate the clinical features and mutations in the SRD5A2 gene in Indian patients with 5RD.

PATIENTS AND METHODS

The SRDSA2 gene was sequenced in two unrelated patients with elevated testosterone/dihydrotestosterone ratio and in one patient with classical clinical features and virilization at puberty (in whom the ratio could not be measured due to prior gonadectomy). The prevalence of SRD5A2 mutations was also studied in 52 healthy ethnic control subjects by PCR-RFLP.

RESULTS

Two patients, both from the north Indian state of Uttar Pradesh, carried the homozygous missense mutation p.R246Q in exon 5. Parents of both probands were heterozygous for the mutation. The mutation was absent in 52 control subjects. The third patient, with severe perineoscrotal hypospadias and micropenis, was detected to have a novel heterozygous missense mutation p.Q56H, as well as the homozygous polymorphism p.V89L, both in exon 1. The p.Q56H mutation was absent in 52 control subjects.

CONCLUSION

p.R246Q is a common SRD5A2 mutation in 5RD patients from the Indian subcontinent.

Single-stage treatment of spina bifida with hydrocephalus based on a prediction rule derived from preoperative cranial ultrasound

AIMS

It was the aim of this study to report a prospective study of 110 spina bifida patients with hydrocephalus treated by simultaneous ventriculoperitoneal (VP) shunt and repair of the meningomyelocele.

METHODS

Between January 2005 and February 2008, 264 patients with spina bifida were admitted to the author's department. Those patients in whom the preoperative cranial ultrasonography measurement of the bifrontal diameter was >26 mm, the bicaudate diameter >20 mm and the diameter of the body of the lateral ventricle >26 mm were predicted to develop postoperative hydrocephalus (n = 245). Of these, 110 patients underwent simultaneous (group 1) VP shunt with repair of the meningomyelocele, while 135 (group 2) underwent sequential surgery due to the preference of the attending consultant.

RESULTS

Twenty-two of the 110 patients in group 1 developed complications (wound problems, cerebrospinal fluid leak, shunt malfunction, death) compared with 38 of 135 patients in group 2. The remaining patients had an uneventful postoperative and follow-up course.

CONCLUSIONS

Simultaneous VP shunt with surgery for hydrocephalus was feasible in our setup. The rate of complications was not higher than in staged surgery. Single-stage repair of spina bifida with hydrocephalus offers considerable advantage in the form of a reduction in hospital burden, costs and patient morbidity.

Anorectal junction stenosis: diagnosis and management

PURPOSE

The aim of this paper is to describe the management of 9 patients with anorectal junction stenosis and present the diagnostic features together with a single-stage surgical technique with reproducible results.

MATERIALS AND METHODS

Nine patients with anorectal junction stenosis were seen over a period of 12 years. The children (aged from 2 months to 15 years) presented with constipation . Anorectal junction stenosis was diagnosed by rectal examination during which the tip of the finger was unable to pass beyond the stenosis in all cases. Contrast study showed the dilated rectosigmoid proximal to the stenosis.

RESULTS

Six patients (who did not have significant rectal dilation) underwent single-stage surgery by posterior Y-V plasty which was curative. Two patients were operated through the posterior sagittal route with a covering colostomy done during the same session; the oldest child required resection of the megasigmoid with abdominoperineal pull-through. None of the six patients operated with Y-V plasty experienced any complications. One of the patients operated via the posterior sagittal route had a leak from the anorectal anastomosis requiring revision. The follow-up ranged from 6 months to 12 years. All patients are alive and well and there was no recurrence of stenosis in any case.

CONCLUSION

Anorectal junction stenosis is a rare anorectal anomaly easily diagnosed by digital rectal examination. Single-stage surgery by posterior Y-V plasty is effective in curing the majority of these patients if significant rectosigmoid dilation is not present.

Esophageal atresia: Factors influencing survival - Experience at an Indian tertiary centre

OBJECTIVE

To study the clinical profile of the cases of esophageal atresia (EA) and/or tracheoesophageal fistula (TEF) and various factors affecting the surgical and early postoperative management and their outcome.

MATERIALS AND METHODS

A prospective analysis of 127 cases of EA from February 2004 to May 2006 was performed. Waterston prognostic criteria were used for grading.

RESULTS

EA with TEF was the commonest type in 117 cases (92%). Associated congenital anomalies were present in 52 (41%) patients, the commonest being the cardiac anomalies, which was followed by the gastrointestinal anomalies. VACTERL was found in 6 (5%) cases. Prematurity, associated congenital anomalies, gap between esophageal ends and preoperative respiratory status were the significant factors affecting the survival (P = < 0.001). Primary extrapleural repair was the surgical approach in most of the patients. Azygos vein was preserved in 46 cases and no retropleural drainage was used in 27 cases. Staged procedures were performed in 19 cases, including 6 cases of isolated esophageal atresia. Pneumonitis and sepsis were the most common early postoperative complications (42%). Hypoxia and cardiorespiratory arrest were the most common causes of mortality (11 cases). Anastomotic leak complicated 13 cases, including 9 major and 4 minor leaks. Major leak followed by sepsis caused 7 deaths. Survival as per Waterston criteria was 100% in group A, 83% in group B and 22% in group C.

CONCLUSION

Factors affecting the survival are major or life-threatening associated anomalies, long gap, pneumonia and sepsis at presentation or that acquired during hospitalization and major leaks. The high incidence of low birth weight, delayed diagnosis, poor referral, low-socio economic status and lack of advanced neonatological back up are important contributory factors to poor outcome.

Unusual ventriculoperitoneal shunt extrusion: experience with 5 cases and review of the literature

Distal migration of ventriculoperitoneal shunt is rare. We present this unusual complication in 5 patients. The lower end of the shunt was extruded from right lumbar region, cervical area, umbilicus and rectum. The cause of such extrusion is not known. The patients were managed by shunt removal followed by shunt replacement on the opposite side.

Spontaneous biliary perforation in infancy and childhood: clues to diagnosis

Spontaneous perforation of extrahepatic bile duct is rare. The cause is idiopathic once trauma and choledochal cyst are ruled out. The condition presents a diagnostic dilemma. Preoperative recognition is necessary as early surgical intervention gives excellent prognosis. We report clinical observations made in three cases with acute presentations. Diagnosis is to be suspected by the presence of jaundice after an initial anicteric period of good health with biliary ascites. This is confirmed by bilious abdominal paracentesis, signs of peritonitis and absent free gas on X ray. The constellation of these three findings was constant in three patients. The presented paper highlights the same as reliable clues to diagnosis.
