Analysis of postoperative complications in patients undergoing anorectal malformation surgery: are there any predisposing factors?

Objective: To describe our experience with anorectal malformation (ARM) patients, while analyzing complications and risk factors.

Materials And Methods: A retrospective study of ARM patients aged 0-18 years old undergoing surgery from 2006 to 2023 was carried out. Demographic variables, associated malformations, age and repair surgery operating times, presence and type of colostomy, previous intestinal preparation, and presence and type of surgical complications -intestinal occlusion, anal prolapse, stenosis, bleeding, dehiscence, extrusion, anoplasty misposition, urethral perforation, and stomal complications- were collected.

Have acute appendicitis complications increased in children as a result of SARS-CoV-2?

Introduction: The impact of the SARS-CoV-2 pandemic on healthcare has already been described, since it has caused an increase in diagnostic delay and morbidity. Our objective was to assess its influence on the development of complications in children with acute appendicitis.

Materials And Methods: A retrospective cohort study was carried out.

Pandemic's impact on inguinal hernia management in infants.

Introduction: The SARS-CoV-2 pandemic brought about a reduction in surgical activity. The objective of this work was to analyze its impact on inguinal hernia morbidity.

Material And Methods: A retrospective study of cases and controls was carried out.

[Postcholecystectomy syndrome in children, fact or fiction?].

Introduction: The postcholecystectomy syndrome (SPC) is broadly defined and published in adults, whereas in the pediatric population are hardly any articles about it. Up to a third of adults have dyspeptic symptoms without organic cause the first year after cholecystectomy. Our goal is to determine the incidence of SPC in our population.

[Treatment of the postoperative bowel obstructions in children: laparoscopic vs. open adhesiolysis].

Objective: To compare the results of laparoscopic versus open adhesiolysis in children affected by postoperative bowel obstruction.

Methods: Retrospective study reviewing charts of all patients who were operated on due to postoperative adhesions in our Department. Demographic data, clinical characteristics and postoperative data were collected.

[Ileostomy closure after necrotizing enterocolitis. When is the best moment?].

Introduction: In more than 50% of the necrotizing enterocolitis that underwent surgery will require an ileostomy. The optimal time to reestablish intestinal transit still is a controversial subject. Many times ileostomies cause medical issues that require early intestinal reconstruction.

Microureteroscopy in Children: Two First Cases.

Background: Urinary stones disease is becoming more common not only in adults but also in children. Most cases are resolved with extracorporeal shock wave lithotripsy, but miniaturization of endoscopes has increased the use of ureteroscopy in resolving ureteral stones, most notably in children.

Case Presentation: This presentation focuses on two cases of microureteroscopy.

[Our experience in retroperitoneoscopic total or partial nephrectomies].

The retroperitoneal laparoscopic approach is displacing open surgery and transperitoneal approach for several benign renal conditions. In the past 6 years we have performed 20 procedures, 10 with lateral position and 10 with posterior prone one: 13 total nephrectomies and 7 heminephrectomies in children aged 4,1 years on average. Mean operative time was 200 minutes in partial procedures and 278 in the total ones.

[Utility of urine levels of interleukins in the diagnosis of vesicoureteral reflux: a case-control study in children].

Unlabelled: Invasive imaging methods that require catheterization are used for the diagnosis of vesicoureteral reflux. Our aim is to assess the usefulness of interleukin urinary levels for the diagnosis of reflux in children without urinary tract infection.

Methods: Case-control study in children who underwent a voiding cystourethrogram: forty cases diagnosed of reflux and 80 controls.

[Acute abdomen caused by infected duodenal duplication].

Infected cystic duplications of the duodenum are unusual lesions. We report two cases of duodenal duplications complicated by infection. The literature is reviewed, and the diagnostic modalities and management options for this unusual pathology are discussed.

[Partial duplication of chromosome 4q (q31, q35): Auriculo-acro-renal syndrome].

The partial trisomy 4q is a strange chromosomal illness. This illness is caused by the duplication of a portion of chromosome 4. In most of the cases, it is the result of a balanced translocation in one of the progenitors.

[Neurocristopathies: a high incidence of cerebral dysgenesis in patients with Hirschsprung's disease].

Introduction: Hirschsprung's disease (HD), or aganglionic megacolon, is a congenital disorder that is characterised by the absence of ganglion cells in the submucosal and myenteric plexuses of the intestine, which is caused by the failure of these cells to migrate from the neural crest (neurocristopathy). Cerebral dysgenesis and polymalformation syndromes have been reported in association with HD, thus suggesting an abnormal morphogenesis.

Aim: To study the frequency of cerebral malformations in patients with HD in our environment.

[External tutor of ePTFE in tracheal stenosis. Clinical application].

Acquired tracheal stenosis in children can be either to direct cervicothoracic trauma or to post-intubation. Resection and end-to-end anastomosis continues to be the treatment of choice. The high rate of restenosis is directly related to anastomotic tension in resections of more than 2 cm.

[Necrotizing histiocytic lymphadenitis (Kikuchi-Fujimoto disease) in a 7-year-old girl].

Kikuchi-Fujimoto's disease is a rare self-limited condition of young adults that usually involves the cervical lymph nodes and is associated with fever, rash and some haematological alterations. Diagnosis is based on characteristic pathologic findings that permit differentiation of this disease from lymphoma, systemic lupus erythematous and infectious lymphadenopathies. We describe a case of 7 year-old female presenting with cervical localization of Kikuchi-Fujimoto's disease.

[Anal fistula treatment with seton].

The objectives of anal fistula treatment are to drain sepsis, irradicate the fistulous tract, and to preserve sphincter integrity and function. These goals can be achieved by either fistulotomy or fistulectomy. Alternative techniques include chemical setons, drainage setons, cutting setons and two-stage seton fistulotomy.

[Usefulness of ultrasonography in the initial assessment of blunt abdominal trauma in children].

Abdominal injuries are frequent in children, and the early assessment is the best guaranty for an accurate management. Although computed tomography (TAC) has been considered the diagnostic modality of choice for children with blunt abdominal trauma, is a costly radiological test that requires the patients be stable and sedated. The aim of this study is to evaluate the usefulness of abdominal ultrasonography, a quick, non-invasive technique, of low cost, and repeatable, during the initial assessment of these patients, arguing about the possibility of replace TAC in the detection of intra-abdominal posttraumatic injury.

[Megacalycosis diagnosed during the study of antenatal hydronephrosis].

We describe a case of megacalycosis in a newborn female with a probable antenatal ultrasonographic diagnosis of left multicystic dysplastic kidney. Uroradiology, ultrasonography and nuclear medicine studies were performed and diagnosis was established by excretory urogram. We have found only one previously published case of megacalycosis in which diagnosis was made during the postnatal study of antenatal hydronephrosis.

[Intravesical knot of Foley catheter: unusual complication of cystourethrography in children].

We report a rare complication of knotting of the urethral catheter inside the urinary bladder of a 3 month old boy who was referred for voiding cystourethrogram. After unsuccessful attempts to remove the catheter, the baby was admitted to surgery. The catheter was removed under anesthesia after gentle but sustained traction.

Wet umbilicus caused by pancreatic heterotopia in urachal remains.

Drainage from the umbilicus may be due to the presence of structures derived from the vitelline duct or urachus, granulomas, ectopic tissue, or poor hygienic practice. This paper discusses the case of a 6-month-old infant with a wet umbilicus caused by ectopic pancreatic tissue, in urachal remains. No similar cases have been found in the literature.

An experimental model for the prevention of postanastomotic tracheal stenosis.

Objective: The aim of the current study is to determine the efficiency of an external prosthesis made of expanded polytetrafluoroethylene reinforced with a continuous silicone spiral to prevent postanastomotic stenosis after surgical correction of extensive tracheal defects in rabbits.

Methods: Forty-five rabbits were used, divided into three groups of 15 animals each. Group A was the control group.
