Objective: The aim of this study was to determine the feasibility of using the ileal neobladder as a substitute for the urinary bladder following total pelvic exenteration for rectal carcinoma. Patients and Methods: Between 1992 and 1998, we performed total pelvic exenteration with ileal neobladder in 5 men with rectal carcinoma. Four patients had primary tumors, and one had recurrent disease after low anterior resection for rectal carcinoma. Histological types were adenocarcinoma in 4 and squamous cell carcinoma in 1. Invaded organs were: the urinary bladder in 1, the urinary bladder and prostate in 2, the prostate and seminal vesicle in 1, and the prostate in 1. Results: There was no operative death. In 1 patient, an ileal conduit was needed because of partial necrosis of the neobladder. Minor leakage on the dorsal wall of the neobladder occurred in 2 patients, which was successfully stopped with simple closure and a gluteus maximus fasciocutaneous flap, respectively. All except one patient with the ileal conduit could void via the urethra. Complete daytime urinary continence was achieved, but nocturnal continence was maintained with voiding once or twice per night. As the urodynamic state, the mean maximum flow rate was 20.9 ml/s (range 9.0–34.1), the mean average flow rate was 7.7 ml/s (range 3.0–11.0), and the mean voided volume was 285.5 ml (range 160–432). The mean length of follow-up was 47.8 months. One patient died of local recurrence 38 months postoperatively, and 1 died of pneumonia 10 months postoperatively. Both patients could void via the urethra until death. The other three patients are currently alive without any evidence of recurrence. Conclusions: Although total pelvic exenteration is a laborious surgical procedure, an ileal neobladder could be a good alternative to the urinary bladder enabling the patients to void via the urethra with urinary continence.

Some patients with intestinal failure, who are dependent on total parenteral nutrition for long periods, suffer from a lack of suitable conventional venous access points, including axillary, external jugular, internal jugular, subclavian, saphenous, and the brachio-cephalic and femoral veins, due to their occlusion. Furthermore, extensive central venous stenosis and/or thrombosis of the superior and inferior vena cava may preclude further catheterization, so uncommon routes must be used, which can be challenging. In such patients, the azygos vein via the intercostal vein is a viable candidate. Thoracotomy-assisted, thoracoscopy-assisted, and cut-down procedures are currently suggested such access. We found that ultrasound-guided percutaneous puncture method was a safe and minimally invasive approach and successfully placed two central venous lines in preparation for small bowel transplantation via two different intercostal veins (ninth and tenth). Although the lung was actually located just below the target veins, an ultrasound provided augmented and clear vision, which contributed to the safe performance of the procedure without the need for invasive surgical intervention, such as thoracotomy, thoracoscopy, or rib resection using the cut-down technique. Furthermore, constant positive-pressure ventilation during vein puncture under general anesthesia also helps avoid venous collapse. Despite carrying a slight risk of light injury to the lung, artery, and nerve along with the vein compared to other procedures, we believe that ultrasound-guided puncture under general anesthesia is feasible as a minimally invasive method.

Background Biliary atresia in very low birth weight (VLBW) and extremely low birth weight (ELBW) infants is rarely reported, and the optimal timing of Kasai portoenterostomy (KPE) in these cases remains unclear. Case presentation We report a case of biliary atresia in a preterm female infant of 24 weeks of gestation who weighed 824 g. She underwent exploratory laparotomy and intraoperative cholangiography at 58 days of age (weight, 1336 g). Despite the diagnosis of biliary atresia with a type I cyst, we could only perform gallbladder drainage at that time due to the unstable intraoperative condition. While we waited for her body weight to increase, KPE was performed at 122 days of age (corrected age: 16 days), when the patient weighed 2296 g. Although she initially became jaundice-free, her liver function deteriorated due to cholangitis, and she developed decompensated cholestatic liver cirrhosis. Living donor liver transplantation was successfully performed at 117 days after KPE, and the postoperative course was uneventful. The timing of KPE is difficult to determine and a review of the relevant literature revealed that a poor prognosis in VLBW and ELBW infants with BA. Conclusions Early KPE and careful postoperative follow-up, including liver transplantation is important for the improvement of outcomes.

Gastrointestinal bleeding or perforation following influenza infection is rare. We encountered a pediatric case of hemorrhagic duodenal ulcer following influenza A infection. The patient was a 1‐year and 4‐month‐old boy who was diagnosed with influenza A infection and treated with laninamivir octanoate. After inhalation, he had diarrhea, poor appetite, and melena. The next day, he had hematochezia and developed hemorrhagic shock. Contrast‐enhanced computed tomography showed extravasation in the descending part of the duodenum. Esophagogastroduodenoscopy revealed spurting bleeding from a Dieulafoy's lesion on the oral side of the major papilla, and he underwent hemostasis by clipping. From the bulb to the descending part of the duodenum, the mucosa appeared atrophic with spotty redness on the circular folds and multiple and irregularly shaped erosions. Almost all mucosal lesions had healed by the eighth day, and he was monitored as an outpatient for more than one year without re‐bleeding. Intestinal ischemia, viral invasion, and drug reaction of laninamivir octanoate may be involved in duodenal mucosal injury. Acute duodenal ulcers may occur in children with influenza infection, especially young children.
