Roux-en-Y partial volvulus in biliary-digestive reconstruction in children.

Various complications occur after a biliary-digestive reconstruction. Volvulus of a segment of the biliodigestive loop has not been described. Two patients who underwent biliodigestive bypass, years later, began with sudden and intense abdominal pain, associated with a volvulus with necrosis of a segment of this biliodigestive loop.

Priapism and chronic myeloid leukemia in an adolescent. Rare debut presentation. A case report.

Priapism is a painful and persistent erection, with or without sexual stimulation. A rare cause of such abnormality is chronic myeloid leukemia. Few cases of priapism as an initial manifestation of this type of leukemia have been reported in adolescent patients.

Laparoscopic vs Open Extravesical Ureteral Reimplantation in Pediatric Population: A Single-Center Experience.

Purpose: To evaluate the safety and efficacy of conventional laparoscopic vs open Lich-Gregoir ureteral reimplantation in pediatric vesicoureteral reflux.

Material And Methods: A retrospective study was conducted in a tertiary care hospital. Patients with vesicoureteral reflux who underwent open or laparoscopic Lich-Gregoir ureteral reimplantation from 2013-2020 were included.

Intraoperative Endoscopy as an Adjuvant to Minimally Invasive Surgery in Pediatrics.

Minimally invasive surgery has a different visual and tactile perception compared with conventional surgery, which could lead to complications, especially in complex procedures. In these cases, flexible endoscopy can facilitate and prevent complications in minimally invasive procedures in children. The study aimed to clarify the utility of intraoperative endoscopy as an adjuvant to minimally invasive surgery in children.

Treatment of chronic pancreatitis by laparoscopic DuVal procedure: report of a pediatric case.

Antecedentes: La pancreatitis es una enfermedad rara. La obstrucción es común y se puede corregir con endoscopia; si fracasa, necesitará cirugía.

Caso ClÍnico: Reportamos un paciente con pancreatitis secundaria a páncreas divisum.

Femoral hernia in children: diagnostic and therapeutic challenge. Case report.

IntroducciÓn: Las hernias femorales son raras en la infancia. El defecto está abajo del ligamento inguinal. La frecuencia de un diagnóstico erróneo es de hasta el 75%.

Laparoscopic Collis-Nissen approach for shortened esophagus treatment in children.

Background: Short esophagus is a disability to obtain a proper portion of abdominal esophagus, thus a lengthening technique is required. Collis approach is the best option.

Objective: To demonstrate effectiveness of laparoscopic Collis-Nissen approach in children.

Laparoscopic Approach of the Obstruction of the Lower Third of the Esophagus in Children.

To review the diagnostic methodology in pediatric patients with obstruction of the lower third of the esophagus as well as minimally invasive therapeutic options. Retrospective study carried out reviewing records of children with esophageal obstruction diagnostic, from 2000 to 2018. They were divided into Group I stenosis secondary to reflux; Group II achalasia; and Group III embryonic remnants.

Management of Pediatric Urolithiasis Using a Combination of Laparoscopic Lithotomy and Pyeloscopy.

Background: Minimally invasive procedures have become the standard option for treatment of urinary stones; the use of more invasive techniques is not a common practice currently. This emergent technology is not always available and laparoscopy is the alternative option. There are few reports of laparoscopic management for urinary lithiasis in pediatric patients.

[Thoracoscopic lobectomy for the treatment of tracheal bronchus. A pediatric case report].

Background: Tracheal bronchus is considered a rare, congenital anomaly, which implies the abnormal origin of a bronchus. When related to repetitive infections the bronchus must be resected, usually via an open procedure.

Objective: The aim of this paper is to present the case of a patient with tracheal bronchus of the upper right lobe who presented with repetitive pneumonias.

[Laparoscopic ureterovesical repair for megaureter treatment].

Background: An alternative treatment for obstructive and refluxing obstructive megaureter with ureterovesical junction maintenance through laparoscopy is proposed.

Material And Methods: The series consists of 8 cases, all of them studied because of prenatal hydronephrosis or febrile urinary tract infection. Seven were diagnosed with obstructive megaureter and one with obstructive refluxing megaureter.

[Minimally invasive treatment for traumatic chylopericardium. Paediatric case report].

Background: Chylopericardium is a rare occurrence in children. The most common causes are associated with cardiac surgery, malformations of the lymphatic system, idiopathic reasons, among others.

Objective: The case is presented of a patient with traumatic chylopericardium, the diagnostic methodology, and in particular, its successful resolution by surgical means.

Selective transperitoneal aspiration of a distended bowel with a small-caliber needle during laparoscopic Nissen fundoplication: a prospective randomized controlled trial.

Introduction: Anecdotal reports have demonstrated the feasibility of needle aspiration to deflate a distended bowel, but we do not know of any prospective study that has evaluated this technique. We designed a controlled study to evaluate the use of the selective transperitoneal needle aspiration of a bowel loop (STAB) in infants.

Materials And Methods: Candidates were patients of less than 6 months of age, scheduled for laparoscopic Nissen fundoplication, in whom severe colonic distension was observed.

[Laparoscopic vs opened appendicovesicostomy in pediatric patients].

Background: Appendicovesicostomy is commonly employed to facilitate drainage of urine through the catheter. Due to the tendency to less invasive procedures for the treatment of patients with neurogenic bladder, laparoscopy has been used as an alternative to open surgery, with the immediate advantages of postoperative recovery, shorter postoperative ileus, better cosmetic results, lower postoperative pain and early reintegration into everyday life.

Purpose: Compare the results of laparoscopic procedure with open appendicovesicostomy.

Laparoscopic ureterocystoplasty with Mitrofanoff system.

Purpose: To describe a laparoscopic surgical technique for ureterocystoplasty in pediatric patients with the Mitrofanoff procedure.

Patients And Methods: The procedure was performed in 4 patients (2 females and 2 males), 8-11 years old (average, 9.5 years), with a history of myelomeningocele and secondary neurogenic bladder.

[Laparoscopic resection of a gastric giant cavernous hemangioma in a child].

Background: Gastric hemangioma rarely appears during the pediatric age, with only thirteen cases in the medical literature. Its manifestations are digestive bleeding and intestinal obstruction. The bleeding can be severe and for such reasons it is usually necessary to apply surgical procedures.

Laparoscopic approach for inguinal hernia in children: resection without suture.

Background/purpose: The laparoscopic treatment of inguinal hernia in children presents a higher frequency of relapse when suture technique procedures are used. Here, we present an alternative technique consisting of laparoscopic resection of the hernia sac without suture according to the physiopathology of pediatric inguinal hernia.

Methods: In prospective studies from June 2006 to January 2011, pediatric patients with a diagnosis of inguinal hernia were subjected to surgery as follows: resection of the hernia sac without suture was performed with a 3-port laparoscopic approach.

Treatment of splenic cyst by laparoscopic partial splenectomy: case report.

Background: Congenital splenic cysts are rare. They have a tendency to bleed, to become infected or to rupture and, for these reasons, must be treated. Treatment using splenectomy has the advantage of not presenting recurrence but carries the risk of immunological complications.
