Single-incision Laparoscopic Surgery for Neonatal Congenital Duodenal Obstruction: A Retrospective Study of 130 Patients.

Objectives: This study sought to assess the advantages of utilizing the single-incision laparoscopic surgery (SILS) procedure for repairing neonatal congenital duodenal obstruction (CDO) in terms of clinical outcomes and complication rates.

Methods: In a retrospective cohort study conducted at a single center, neonates with CDO who underwent SILS were compared to those who underwent conventional laparoscopic surgery (CLS) between January 2018 and December 2022. The demographic and operative characteristics of CDO patients who underwent SILS or CLS were analyzed, including conversion rates and postoperative complications.

Early intervention in Hirschsprung's disease: effects on enterocolitis and surgical outcomes.

Background: The timing of surgical intervention for Hirschsprung's disease (HSCR) has been a topic of continued discussion. The objective of this study was to evaluate the significance of age at surgery in the management of HSCR by conducting a comparative analysis of the correlation between surgical age and midterm outcomes.

Methods: We conducted a retrospective analysis of children with HSCR who underwent one-stage laparoscopic assisted pull-through surgery with modified Swenson technology at our hospital between 2015 and 2019.

Ultrasound promoted catalytic liquid-phase dehydrogenation of isopropanol for Isopropanol-Acetone-Hydrogen chemical heat pump.

The apparent kinetic of the ultrasound assisted liquid-phase dehydrogenation of isopropanol over Raney nickel catalyst was determined in the temperature range of 346-353 K. Comparison of the effects of ultrasound and mechanical agitation on the isopropanol dehydrogenation was investigated. The ultrasound assisted dehydrogenation rate was significantly improved when relatively high power density was used.
