Conservative management of isolated splenic abscess in children

INTRODUCTION Isolated splenic abscesses (SAs) are rare in children. We report a single-center experience with emphasis on their diagnosis, etiology, treatment, and outcome. METHODS This is a retrospective review. RESULTS Eighteen children (age, 3-16 years; male-female ratio, 5:1) were managed over a period of 8 years in a tertiary-care institution. Presenting symptoms included fever, abdominal pain, and anorexia. Splenomegaly was present in 12 (67%), leukocytosis in 9 (50%), and thrombocytosis in 12 (67%) patients. Associated diseases were thalassemia (1), tuberculosis (1), and typhoid fever (9). Solitary and multiple SAs were seen in equal numbers. Blood culture grew Salmonella paratyphi A in 1 case. Splenic aspirate culture was positive in 3 (Escherichia coli [1], S paratyphi A [1], Acinetobacter [1]). Widal serology was positive in 9 (50%) patients. Management consisted of intravenous broad-spectrum antibiotic therapy in all patients, together with percutaneous aspiration in 10 (56%) cases where the abscess size was greater than 3 cm. All patients responded, and complete resolution was observed. CONCLUSION Isolated SA in children responds favorably to conservative treatment with intravenous broad-spectrum antibiotics and percutaneous drainage without the need for splenectomy.

Gastric outlet obstruction without esophageal involvement: A late sequelae of acid ingestion in children

Accidental corrosive ingestion is not a rare occurrence in children because of easy access to strong household cleansers. Gastric injury as a predominant finding following acid ingestion in pediatric age group is less widely known with a few cases being reported in Indian literature. We report two such cases of gastric outlet obstruction following accidental ingestion of dilute acid. Both children have typical clinical presentation just 4-6 weeks after the ingestion. Upper GI endoscopy and barium meal studies confirmed the diagnosis. Early surgical intervention resulted in a satisfactory recovery. Both patients are doing well on follow up.

Use of anorectal manometry for evaluation of postoperative results of patients with anorectal malformation: a study from Kuwait

PURPOSE The objective of this study is to use anorectal manometry for functional assessment of early postoperative results after corrective surgery for anorectal malformations (ARMs) in children and compare manometric observations with age-matched controls. Parents were counseled and management strategies were planned according to the manometric assessments. METHODS From August 2005 to September 2009, 32 patients who underwent surgery for ARM were assessed postoperatively with anorectal manometry using a water-perfused anorectal motility catheter to record anal canal length or high-pressure zone, resting pressure of anal canal (RP), and rectoanal inhibitory reflex (RAIR). These patients were divided in 2 groups (infants, <1 year; children, >1 year) according to the age at the time of performance of anorectal manometry that was done at 6 months or later following stoma closure or anoplasty. RESULTS Out of these 32 patients, high anomaly was present in 13, whereas 19 had low type of defect. Manometric anal canal length of the children with high and low ARM was 2.10 ± .44 and 2.25 ± .53 cm, respectively, which was significantly shorter than that of their age-matched controls(P < .05). In patients with high ARM, RP in infants (17 ± 7.7 mm of Hg) and children (21 ± 9.4 mm of Hg) was lower than that of controls (RP in infants = 42.43 ± 8.19 mm of Hg, RP in children = 43.43 ± 8.79 mm of Hg, P < .001). In patients with low ARM, RP in infants (34 ± 8.6 mm of Hg, P = .002) and children (26 ± 9.9 mm of Hg, P = .001) was lower than that in controls. Presence of RAIR was demonstrated in 5 (38.4%) of 13 patients with high ARM and in 11 (57.9%) of 19 cases with low ARM. Parental counseling was done after this early evaluation, and management strategies like bowel management program and biofeedback training were planned according to the results of the tests. CONCLUSION Our anorectal manometric results suggest that patients with ARM had short anal canal with lower RP and impaired RAIR, which could affect the ultimate functional outcome in these patients. Thus, postoperative anorectal manometric evaluation of the patients with ARM can give more realistic information about future continence and might help in planning future treatment strategies like bowel management program or biofeedback training.

Bilateral adrenal abscess in a neonate

A 23-day-old male baby with a history of perinatal hypoxia presented with refusal of feeds and abdominal distension. The child had a right-sided cystic upper abdominal mass and features of neonatal septicemia. Abdominal ultrasound (US) and contrast-enhanced CT scan showed bilateral adrenal abscesses. Laparotomy with drainage of the abscesses successfully treated the condition. The literature on the subject is reviewed.

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.

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.

Multiple anastomotic complications following repair of oesophageal atresia with tracheoesophageal fistula: A report of two cases

This report describes the clinical course and management of two children with multiple anastomotic complications following primary repair of oesophageal atresia (EA) with distal tracheoesophageal fistula (TEF). These included anastomotic leak and stricture, oesophageal perforation during antegrade dilatation, and finally a recurrent fistula between the oesophagus and the tracheo-bronchial tree. Ultimately, after multiple operative interventions, a successful outcome was achieved in both patients with preservation of the native oesophagus. The anastomotic complications following primary repair of EA with TEF are discussed, with special reference to difficulties in the management of recurrent TEF.

The colovesical fistula in congenital pouch colon: a histologic study

PURPOSE The aim of this study was to perform a detailed histopathologic examination of the terminal colonic pouch and the colovesical fistula (CVF) excised during surgical management of male patients with the more severe forms (types I/II) of congenital pouch colon (CPC) associated with anorectal agenesis. METHODS From January 2005 to December 2006, 25 male patients with types I/II CPC underwent abdominal exploration with dissection of the terminal portion of the colonic pouch and associated CVF till the bladder, division-ligation of the fistula, and excision of the colonic pouch. In 6 of the 25 patients, a complete dissection of the fistula to the bladder was possible, and in them, the terminal portion of the colonic pouch and the CVF were subjected to detailed histopathologic examination. The 6 patients included 3 newborns in whom this surgery was performed as a primary procedure, and 3 patients aged 3 months, 15 months, and 2 years, respectively, in whom a window colostomy of the pouch had earlier been performed. After due processing, multiple sections from the specimens were stained using the routine H&E method and examined under the microscope under different magnifications. RESULTS In 4 specimens, the epithelial lining of the CVF consisted of transitional stratified epithelium with underlying anal/urethral glands. In 2 specimens, obtained from patients 15 months and 2 years old, respectively, the lining was of nonkeratinizing, stratified squamous epithelium. Other findings included aganglionosis in the muscle layers (n = 2), submucosal and subserosal fibrosis (n = 1), and thickening of muscle layers in the fistulous portion, suggestive of the presence of an internal sphincter (n = 2). CONCLUSIONS The CVF in patients with types I/II CPC shows histologic features of the normal anorectal canal.

Prolapsed Urinary Bladder Haemangioma: A Rare Presentation

Urinary bladder haemangiomas are rare benign mesenchymal tumors. They usually present with macroscopic haematuria. We report an unusual case of a 6 month old female child; she presented with a bleeding interlabial mass which turned out to be prolapsed urinary bladder haemangioma.
