Feasibility, safety and outcome of inguinal hernia repair under spinal versus general anesthesia in preterm and term infants.

BACKGROUND: Inguinal hernia repair (IHR) is a common operation in preterm and term infants. Recently, spinal anesthesia (SA) has been proposed as an alternative to avoid exposure to general anesthesia (GA) during early life. The aim of this study was to compare surgical outcomes of open IHR performed under SA versus GA in neonates and infants, and to detect criteria to predict the success or failure of SA. MATERIALS AND METHODS: This is a 6-year, single center, nonrandomized interventional study (2013-2019). SA was performed with 0.5% bupivacaine. GA was given using propofol, fentanyl, sevoflurane, and laryngeal mask. Patient demographics, operative time, intraoperative events related to surgery or anesthesia, and complications were analyzed at short and long-term follow-up. RESULTS: 68 infants (78 IHR) and 37 infants (44 IHR) received SA and GA at the discretion of the anesthesiologist, respectively. SA failure rate was 9%, and positively correlated with weight at surgery (p = 0.001; rp = 0.38). Conversion from SA to GA occurred in 4 (6%) patients owing to prolonged operative time (43.75 ±â€¯4.8 vs 23.02 ±â€¯11.3 min; p = 0.0006). There were no differences regarding operative time and intra- and postoperative complications among the two groups at mean follow-up of 18.53 ±â€¯21.9 months. CONCLUSIONS: This pilot study confirms that SA is safe, effective and not detrimental to surgical outcome of neonates and infants undergoing IHR. Additionally, it may help further define what patients may have a successful SA. Our experience suggests that SA is especially suitable in infants weighing <4000 g, and conversion to GA correlates with prolonged operative time. LEVEL OF EVIDENCE: Level II.

Use of Meckel's diverticulum as a temporary diverting ostomy.

Meckel's diverticulum is among the most common congenital defects of the gastrointestinal tract, and is associated with a total lifetime risk of complications around 4%. While debate on prophylactic resection of incidental Meckel's diverticulum continues, there have been reports of its successful use for urinary diversion and reconstruction. In contrast, its use as a means of fecal diversion has been described anecdotally. Herein, we describe our technique of temporary fecal diversion using Meckel's diverticulum as reliable conduit for stoma formation in a toddler. The stoma functioned well until continuity of bowel was restored and diverticulum resected safely. We trust that our limited experience will encourage other colleagues to test the inventive use of Meckel's diverticulum as a potentially safe and effective option to fit in the surgical armamentarium for temporary fecal diversion. KEY WORDS: Anastomotic leak, Fecal diversion, Ileostomy, Meckel's diverticulum, Stoma.

Volume and function of the operated kidney after nephron-sparing surgery for unilateral renal tumor.

AIM: We sought to assess the magnitude of functional decline and the natural history of the operated kidney residual function after zero-ischemia nephron-sparing surgery (Z-NSS) in children with unilateral renal tumor (URT). PATIENTS AND METHODS: 50 children were treated for URT at our surgical unit between 1992 and 2016. Of these 12 who underwent Z-NSS were available for the current analysis. Operated kidney function was assessed by 99mTc-dimercapto-succinic acid (DMSA) renal scintigraphy. Operated kidney volume was assessed by renal ultrasonography. RESULTS: A positive correlation between split renal function and split renal volume was found (P = 0.001). The subset of patients with ≥40% preservation of operated kidney function/volume (OKF/V) had no-time dependent changes during adolescence. The subset of patients with <40% OKF/V preservation had a catch-up growth that after puberty reached values not much different from those with ≥40% OKF/V preservation. At 5 years of follow-up, 3 of 5 patients with baseline dysfunction (eGFR between 40.8 and 89.4 ml/min/1.73 m2) presented with a global renal function within normal range. After puberty, all patients presented with global renal function within normal values (eGFR between 95 and 151 ml/min/1.73 m2). CONCLUSIONS: In children with URT who underwent Z-NSS, the pattern of OKF/V recovery suggests that compensatory catch-up growth capacity during childhood minimizes OKF/V decline more than Z-NSS. LEVEL OF EVIDENCE: Level I prognosis study - prospective cohort study with >80% follow-up and all patients enrolled at same time point in disease.

Fire in the Operating Room During Hypospadias Repair.

Fire in the operating room (OR) is a very distressful and shocking occurrence with potential dramatic consequences. Despite safety rules and rigorous recommendations, such unintentional events do occur every so often. Notably, the vast majority of cases have been reported in the adult population, with very few pediatric cases described to date. Herein, we report on a 16-month-old boy undergoing reconstructive surgery for penoscrotal hypospadias, who experienced an OR fire most likely related to the use of alcohol-based solution ignited by monopolar electrocautery.
