Early feeding in pediatric patients following stoma closure in a resource limited environment

BACKGROUND Establishment of enteral nutrition is necessary after intestinal surgery. In resource-strained environments, it can be critical. This study examined the effect of early feeding in pediatric patients undergoing stoma closure in a country with mid-level socioeconomic indices. METHODS With parenteral consent and ethics board approval, patients were prospectively enrolled in early feeding (Group 1), starting feeds 24h post-operation with a protocol driven increase. They were compared with similar patients managed without a specific protocol over the 12 months prior (Group 2). RESULTS There were 31 patients in each group with similar mean age and weight. The mean first sustained feed was achieved at 28.5 ± 4.4 h* in Group 1 vs. 153.8 ± 28.6 h in Group 2. Full feeds were achieved within 62.3 ± 19.2 h* vs. 196.0 ± 40.5 h in Group 1 and 2, respectively. Mean hospital stay was 7.2 days* in Group 1 vs. 9.4 days in Group 2. A reduction in postoperative fever and wound infections was observed in Group 1 (*p<0.05). CONCLUSION Early enteral feeding after elective bowel anastomosis is well tolerated in children and results in shorter hospital stay and fewer complications.

Umbilical Signs of Peritoneal Tuberculosis in Children

ObjectivesTo report the observation of involvement of the umbilicus with alteration of its morphology in association with peritoneal tuberculosis.MethodsThis is a retrospective observational case series of abdominal tuberculosis (ATB) in children, treated in the department of pediatric surgery of a tertiary-care children’s hospital in the period from January 2004 through April 2010.ResultsOut of a total of 38 cases of ATB in children, 22(57.9%) were of the peritoneal type, 14(36.8%) were of the intestinal type, and 2(5.3%) involved the mesenteric lymph nodes. Of the patients manifesting with peritoneal tuberculosis, 11 cases (50%) had involvement of the umbilicus with changes in the umbilical shape and appearance. In seven cases the umbilicus was found retracted and transversely oriented (a slit-like “smiling” appearance) with loss of the umbilical hollow. In two cases there was puckering of the umbilicus. Other findings included umbilical erythema with inflammation in one patient and a fecal fistula at the umbilicus in another patient. While seven cases responded to treatment with antituberculous therapy (ATT), four cases underwent surgery (two laparotomy and two laparoscopy). Findings were similar in all four patients, consisting of adhered dilated bowel loops studded with tubercles which also covered the parietal peritoneum and the falciform ligament. All four cases responded to postoperative ATT.ConclusionsMorphological changes of the umbilicus can provide an additional clue to the diagnosis of peritoneal tuberculosis in children.

Anorectal agenesis with rectovaginal fistula: A rare/regional variant

Aims and Objectives: The anatomical types of female anorectal malformation (ARM) are complex and include several rare and regional variants. The aim of this report is to highlight the diagnosis and management of cases of anorectal agenesis with rectovaginal fistula (RVF). Materials and Methods: This is a retrospective chart review of cases of RVF who underwent definitive surgery between November 2000 and September 2016 in a single institution. Results: Of the 244 female patients with anorectal anomalies treated in our institution over a 16-year period, there were 15 cases of RVF with anorectal agenesis giving it an incidence of 6%. All cases of RVF with anorectal agenesis presented with absence of anal opening, varying degree of abdominal distension, and history of passage of fecal matter per vaginum. The mean age of presentation was 3 months (newborn to 1 year). Sigmoid colostomy was done in 13 cases. Distal colostogram demonstrated high RVF which was further confirmed by examination under anesthesia (EUA) and endoscopy before definitive surgery. With the posterior sagittal approach, division of the RVF and anorectoplasty was possible in 14 cases; however, one patient required an abdominal mobilization of the colon for pull through due to a very short distal bowel segment. During a mean postoperative follow-up of 5 years, cosmetic and functional results were satisfactory. Conclusion: RVF with anorectal agenesis is a rare/regional variant of female ARMs. Clinical examination along with distal colostogram, EUA, and endoscopy clinches the diagnosis. Anorectal reconstruction by posterior sagittal anorectoplasty results in a satisfactory outcome.

Congenital pouch colon and segmental dilatation of the colon: A report of two unusual cases

This report describes two unusual cases of anorectal malformation. The first had a type III congenital pouch colon with a colovesical fistula. In the other very similar case, segmental dilatation of the colon was present along with penoscrotal hypospadias and, distally, a length of normal colon ending in a rectourethral fistula. In both patients, the appendix was short, stubby and a Y-shaped duplication of the normal colon was present just proximal to the dilated segment of colon.

Determinants of gap length in esophageal atresia with tracheoesophageal fistula and the impact of gap length on outcome

Aim: This study was aimed at identifying factors which may affect the gap length in cases of esophageal atresia with tracheoesophageal fistula (EA-TEF) and whether gap length plays any role in determining the outcome. Materials and Methods: All consecutive cases of EA-TEF were included and different patient parameters were recorded. Plain radiographs with a nasogastric tube in the upper esophagus were taken. Patients were grouped into T1-T2; T2-T3; T3-T4; and T4 depending on the thoracic vertebral level of the arrest of the tube. During surgery, the gap length between the pouches was measured using a Vernier caliper and the patients were grouped into A, B, and C (gap length >2.1 cm; >1-≤2 cm and ≤1 cm). The operative gap groups were compared with the radiography groups and the other recorded parameters. Results: Total numbers of cases were 69. Birth weight was found to be significantly lower in Group A (mean = 2.14 kg) as compared to Group B (mean = 2.38 kg) and Group C patients (mean = 2.49 kg) (P = 0.016). The radiographic groups compared favorably with the intraoperative gap length groups (P < 0.001). The need for postoperative ventilation (70.83% in Group A vs. 36.84% in Group C, P = 0.032) and mortality (62.5%, 26.9% and 15.8% in Group A, B, and C, respectively, P = 0.003) co-related significantly with the gap length. Conclusion: Birth weight had a direct reciprocal relationship with the gap length. Radiographic assessment correlated with intraoperative gap length. Higher gap length was associated with increased need for postoperative ventilation and poor outcome.

Pediatric esophageal substitution by gastric pull-up and gastric tube

Aim: The aim of this study was to report the results of pediatric esophageal substitution by gastric pull-up (GPU) and gastric tube (GT) from a tertiary care pediatric center. Materials and Methods: Retrospective analysis of the surgical techniques, results, complications, and final outcome of all pediatric patients who underwent esophageal substitution in a single institution was performed. Results: Twenty-four esophageal substitutions were performed over 15-year period. The indications were pure esophageal atresia (EA)-19, EA with distal trachea-esophageal fistula-2, EA with proximal pouch fistula-1, and esophageal stricture in two patients. Mean age and weight at operation were 17 months and 9.5 kg, respectively. GPU was the most common procedure (19) followed by reverse GT (4) and gastric fundal tube (1). Posterior mediastinal and retrosternal routes were used in 17 and 7 cases, respectively. Major complications included three deaths in GPU cases resulting from postoperative tachyarrhythmias leading to cardiac arrest, cervical anastomotic leak-17, and anastomotic stricture in six cases. Perioperative tachyarrhythmias (10/19) and transient hypertension (2/19) were observed in GPU patients, and they were managed with beta blocker drugs. Postoperative ventilation in Intensive Care Unit was performed for all GPU, but none of the GT patients. Follow-up ranged from 6 months to 15 years that showed short-term feeding difficulties and no major growth-related problems. Conclusions: Perioperative tachyarrhythmias are common following GPU which mandates close intensive care monitoring with ventilation and judicious use of beta blocking drugs. Retrosternal GT with a staged neck anastomosis can be performed without postoperative ventilation.

A case series study of therapeutic implications of Type IIIb4: A rare variant of esophageal atresia and distal tracheoesophageal fistula

BACKGROUND A wide spectrum of variations can occur in type IIIb esophageal atresia and distal tracheoesophageal fistula [EA-TEF] (Kluth D. Atlas of esophageal atresia. J Pediatr Surg 1976; 11 (6):901-19). The aim of this study was to evaluate the variant anatomy of subtype IIIb4 EA-TEF and its therapeutic implications. METHODS We performed a retrospective review of 4 patients of this variant subtype within a series of 259 esophageal atresias, managed over a study period of three years, at our institution. The diagnosis was made at thoracotomy. The overlapping upper and lower esophageal pouches, initially, gave a false impression of esophageal continuity. The long TEF coursed parallel in proximity to the upper pouch (UP) and the trachea needing meticulous dissection. The TEF measured 8-10mm in diameter and was ligated and divided high on the trachea near the thoracic inlet. The patients were followed up by a contrast swallow, radioactive technetium-99m- sulfur colloid scan, echocardiography and bronchoscopy (if indicated). RESULTS The mean birth weight and gestational age was 2250 g and 38 weeks respectively. The mean follow up was eighteen months (range 5-42 months). An associated anorectal malformation was present in two patients while none had associated congenital heart disease. The Waterston grading was A and B in one patient each and C in two patients. All the patients had muscular UP extending up-to the level of arch of azygous vein (T(3-4)). The lower esophageal pouch (LP) and the fistula extended high, near the thoracic inlet. Tracheal injury occurred in one patient, with thin LP, warranting postoperative elective ventilation. A postoperative barium swallow did not reveal anastomotic leak or stricture in any patient. Follow-up barium swallow showed long LP extending high up in the chest, up to clavicles in all four patients and redundancy of UP in case 1. Severe gastroesophageal reflux was present in two patients. Bronchoscopy revealed tracheomalacia in case 1. Three patients were thriving well at the last follow-up. One patient died at five months of age due to aspiration pneumonia. CONCLUSIONS The knowledge of diagnostic and therapeutic implications of the variant subtype IIIb4 EA-TEF should be in the armamentarium of the treating surgeon to reduce pitfalls in its management.
