Treatment of impalpable testis - one clinic's experience.

INTRODUCTION: Undescended testes are recognised in 1% to 2% of boys during the first year of life, and about 20% of them are impalpable. Ultrasonography (US) may establish the localisation of the testis but the final diagnosis is usually determined laparoscopically. AIM: To evaluate long-term results of laparoscopic treatment of boys with impalpable testes and sensitivity of preoperative ultrasound. MATERIAL AND METHODS: Between 2011 and 2015, we operated on 545 boys with undescended testes. Sixty-two of them with 65 impalpable testes were treated laparoscopically - the study group. Mean age was 3.5 years. The study group was divided into 5 groups according to type of treatment. The volume and position of the operated gonad were assessed manually and by ultrasound. RESULTS: In group 1 testicular agenesis was observed in 19 patients. In group 2 revision of the inguinal canal revealed testicular agenesis in 7 and atrophy in 4 patients. In group 3 conversion to classic orchiopexy was performed in 10 patients. In group 4 one-stage orchiopexy was performed in 9 patients on 12 testes. In group 5 a two-stage F-S procedure was performed in 13 patients. Ten testes in group 4 had a volume in the normal range (84%) and also 10 testes in group 5 (77%). CONCLUSIONS: Laparoscopy in impalpable testes is the procedure of choice and allows definitive management, even when conversion to open procedure is necessary. Sensitivity of preoperative ultrasound is generally about 60% for true intra-abdominal testes, so diagnostic laparoscopy is necessary.

Central Pancreatectomy as a Good Solution in Frantz Tumor Resection: A Case Report.

Solid pseudopapillary tumors of the pancreas located in the head or body are a challenging clinical problem because they usually demand extensive surgical procedures, and in most reported cases pancreaticoduodenectomy is the operation of choice in such a location. An alternative method of surgery in precisely selected patients is a procedure known as central pancreatectomy. The authors present the case of a 13-year-old girl with a 5 cm tumor located in the body of the pancreas. The favorable anatomical location of the tumor suggested central pancreatic resection. The tumor was excised with 1 cm oncologic margins from both sides, and the distal remnant of the pancreas was protected with a Roux-en-Y loop. In the postoperative period the patient required reoperation because of intensive bleeding in the resection site but the duodenal loop was saved and the patient protected from biliary tract reconstruction and exocrine and endocrine insufficiency. Progress in pancreatic surgery, especially in children, allows less radical options for the reason that preservation of endocrine and exocrine function is very important and protects them, especially from insulin-dependent diabetes in the future.

Thoracoscopic repair of esophageal atresia with a distal fistula - lessons from the first 10 operations.

INTRODUCTION: Thoracoscopic esophageal atresia (EA) repair was first performed in 1999, but still the technique is treated as one of the most complex pediatric surgical procedures. AIM: The study presents a single-center experience and learning curve of thoracoscopic repair of esophageal atresia and tracheo-esophageal (distal) fistula. MATERIAL AND METHODS: From 2012 to 2014, 10 consecutive patients with esophageal atresia and tracheo-esophageal fistula were treated thoracoscopically in our center. There were 8 girls and 2 boys. Mean gestational age was 36.5 weeks and mean weight was 2230 g. Four children had associated anomalies. The surgery was performed after stabilization of the patient between the first and fourth day after birth. Five patients required intubation before surgery for respiratory distress. Bronchoscopy was not performed before the operation. RESULTS: In 8 patients, the endoscopic approach was successfully used thoracoscopically, while in 2 patients conversion to an open thoracotomy was necessary. In all patients except 1, the anastomosis was patent, with no evidence of leak. One patient demonstrated a leak, which did not resolve spontaneously, necessitating surgical repair. In long-term follow-up, 1 patient required esophageal dilatation of the anastomosis. All patients are on full oral feeding. CONCLUSIONS: The endoscopic approach is the method of choice for the treatment of esophageal atresia in our center because of excellent visualization and precise atraumatic preparation even in neonates below a weight of 2000 g.
