Patients with this phenotype differ widely in the severity of the hypospadias and the complexity of the surgical repair. We aimed to investigate the operative findings and the outcomes of consecutive patients who presented with this phenotype.Methods: We retrospectively reviewed the medical charts of 31 consecutive patients who underwent hypospadias repairs from January 2014 to May 2017, and the hypospadias was characterized by i) the external urethral meatus at coronal/subcoronal region, ii) scrotal skin encroaching distally resulting in fixation of penoscrotal angle at distal penile shaft, and iii) urethral plate below the glans on penile shaft invisible or barely visible.Results: The median age at the time of surgery was 15.5 months (10–63). The division of corpus spongiosum was noted at distal penile shaft (n=2; 6.5%), mid-shaft (n=5; 16.1%) and proximal location (n=24; 77.4%). The median ventral curvature before degloving was 45 degrees (10–90). Twenty-eight and 3 patients underwent tubularized incised plate and 2-stage preputial flap repairs, respectively. Twenty-nine of 31 patients required cutback of the hypoplastic urethra. At the time of urethroplasty, 2 (6.5%), 7 (22.6%) and 22(70.9%) patients underwent distal, mid-shaft and proximal repairs, respectively. At a median follow-up of 30 months (14–50), 6 (19.4%) patients developed one or more complications (fistula=3; meatal stenosis=5).Conclusion: Patients affected by this particular phenotype likely require non-distal hypospadias repair with possibly higher complication rate and should be treated by surgeons with expertise in complex hypospadias repair.Keywords: hypospadias, division of corpus spongiosum, distal penile penoscrotal angle fixation

Abstract

Foreign body ingestions are frequent in the childhood population. Most foreign bodies are passed spontaneously through the gastrointestinal tract. However, on occasion, they can also be a rare cause of morbidity and even mortality, such as in the case of multiple magnetic foreign body ingestion, which can cause injury via magnetic attraction through bowel walls. We present two cases of multiple magnetic foreign body ingestion, which to our knowledge are the first ones reported in Hong Kong. One patient presented with shock and intestinal necrosis requiring extensive intestinal resection, whereas the other patient had no gastrointestinal injury but surgical removal was deemed necessary.

Abstract

Yuen Shan Wong, Yuk Him Tam, Kristine Kit Yi Pang Division of Paediatric Surgery and Paediatric Urology, Department of Surgery, Prince of Wales Hospital, The Chinese University of Hong Kong, Shatin, NT, Hong Kong Abstract: We report on two children aged 2 and 6 years, who underwent laparoscopic ipsilateral ureteroureterostomy for their renal duplex anomalies. Both patients had complete duplex and were investigated by ultrasound, micturating cystourethrogram, magnetic resonance urography, and radioisotope scan. One patient had high-grade vesicoureteral reflux to lower moiety complicated with recurrent urinary tract infections, while the other had obstruction to upper moiety due to ectopic ureter. The pathological moieties of both patients were functional. Both patients underwent laparoscopic ipsilateral ureteroureterostomy uneventfully without any intraoperative complications. Postoperative imagings confirmed successful outcomes after surgery. Keywords: laparoscopic ipsilateral ureteroureterostomy, renal duplex, children

Abstract

Aim: The authors report a technique to perform single-incision laparoscopic combined cholecystectomy and splenectomy in 3 children using conventional instruments., Methods: Three ports, including 5-mm and 3-mm ports, were placed through an infraumbilical incision for the procedure. Splenectomy was completed in most parts by crossing the 2 straight instruments., Results: The 3 patients, aged 11 to 13 years, with body weight 29 kg to 32 kg, underwent the procedure. In the first patient, 2 additional extraumbilical 5-mm ports were required to complete the splenectomy. After modification of the technique, combined cholecystectomy and splenectomy by SILS were successfully performed in the other 2 patients without complications, and postoperative courses were uneventful., Conclusions: Combined cholecystectomy and splenectomy in children by SILS is technically feasible using conventional instruments. Further studies are required to investigate its safety, benefits over conventional laparoscopic surgery, and refinements in the technique.
