Hirschsprung's associated enterocolitis (HAEC) is a complication of Hirschsprung's Disease (HD) with considerable morbidity and mortality. The variability in presentation leads to a wide variety of the reported prevalence pre-and postoperatively. This systematic review aimed to clarify the prevalence of HAEC in short-(S-HD), long (L-HD), TCA and the type of operation used.

Prevalence of Hirschsprung-associated enterocolitis in patients with Hirschsprung disease.

Patients suffering from complete colonic aganglionosis (TCA) require the best surgical care possible. Only a few studies reported J-Pouch repair as the primary reconstructive surgery in TCA patients. This study adds to the current literature a thorough clinical and functional outcomes group.

Colectomy Followed by J-Pouch Reconstruction to Correct Total Colonic Aganglionosis.

 The transition zone (TZ) is defined by specific histological findings in patients with Hirschsprung Disease (HSCR). HSCR treatment includes surgical removal of the aganglionic zone (AZ). During the pull-through procedure, it is critical to resect the TZ. Given the TZ's wide histological heterogeneity, we wanted to know how extensive the histological transition zone is.  A retrospective study of patients who had pull-through surgery for rectosigmoid HSCR between January 2010 and December 2020 was carried out. Demographics, length of TZ and AZ, age and symptoms upon presentation, and complications after surgery were also obtained.  The inclusion criteria were met by 50 patients. The mean age of all patients was 10 months (0.1-107.5 months), with a mean age at pull-through of 16.3 months (3-112 months). Thirty-one out of fifty patients (62%) received primary laparoscopic endorectal pull-through surgery (LEPT). The average TZ length of all patients was 2.6 cm (0-10 cm), and the AZ length was 9.6 cm (1-30 cm). The length of the AZ and TZ were shown to have no correlation (r² = 0.237).  The current study found that the mean length of the TZ in individuals with rectosigmoid HSCR is less than 5 cm in most cases and has no correlation with the length of the AZ.

The Length of the Transition Zone in Patients with Rectosigmoid Hirschsprung Disease.

The quality of life of patients with Biliary Atresia (BA) have not been systematically examined. The goal of this meta-analysis is to determine patients' postoperative health-related Quality of life (HrQoL) with native or transplanted livers.

Systematic review: The quality of life of patients with biliary atresia.

The aim of this paper is to assess the effectiveness and perioperative complications of splenic surgeries in children. In 41 splenectomies, an anterior abdominal laparoscopic approach was used, with 35 including a partial laparoscopic splenectomy. Of these, three needed a conversion to open. Six patients had a total splenectomy, three of which were open. Patients ranged in age from 5 to 18 years. Splenectomy was performed for a variety of causes, including hereditary spherocytosis ( = 20), splenic cysts ( = 13), sickle cell disease ( = 3), primary malignancy ( = 1), sepsis ( = 1), embolism ( = 1), anemia ( = 1), and hypersplenism ( = 1). The average length of stay was 7.6 days, and the average operation time was 169.3 min. Pleural effusion in the left hemithorax was found in 31.6% of the patients, with 5.3% requiring a thorax drain. The majority of patients had the highest platelet count two weeks after surgery. There was no evidence of wound infection, pancreatic leak, colon perforation, or postoperative sepsis. The most encountered perioperative complication was bleeding with the need of transfusion ( = 6), and one patient needed a diaphragm repair. A partial splenectomy (PS) can be a difficult procedure with a steep learning curve. For most children who require a splenic operation, this should be the primary procedure of choice.
