- CONCLUSIONS: Use of monopolar coagulation with NBCA in clampless and sutureless LPN for renal tumors with low RENAL nephrometry scores is safe and effective. For patients with exophytic renal tumors less than 2 cm, NBCA is not necessary.

Objective: To study the safety and feasibility of using monopolar coagulation in sutureless laparoscopic partial nephrectomy (LPN). Methods: From February 2015 to March 2016, sutureless LPN using monopolar coagulation was performed on 25 patients with renal tumors. Mean patient age was 50 years (range 31 to 68). Mean tumor size was 4.1 cm (range 1.2 to 10.1). Mean RENAL nephrometry score was 6.1 (range 4 to 12). The renal hilar vessels were clamped in 14 surgeries, whereas 11 surgeries were carried out without clamping. The tumors were resected by cold scissors and monopolar hook. The tumor beds were coagulated by monopolar hookrepeatedly in spray and fulgurate modes.N-butyl-2-cyanoarcrylat (NBCA) was used in 13 patients when bleeding was observed after coagulation. Results: Mean operative time was 129.6 mins (range 70 to 300). Mean warm ischemic timein clamped cases was 22.6 min (range 15 to 32). Mean estimated blood loss was 166 ml (range 10 to 800). Mean hospital stay was 16.2 days (range 7 to 36). Two patients received blood transfusions. One patient received open surgery and suturing repair after failure of selective arterial embolization for postoperative hemorrhage. Two patients had urine leakage without any intervention. Conclusions: The technique using monopolar coagulation in sutureless LPN was safe and feasible. For exophytic and small tumors, the off-clamped technique could berecommended.
- Video-assisted treatment of pilonidal disease, using a combination of diathermy ablation and phenol application. [Case Reports]

Video-assisted diathermy ablation (VADA) and crystallised phenol application (CPA) have been independently suggested as minimally invasive treatment options for sacrococcygeal pilonidal disease (SPD). The failure rates may be 5-33% with either method, and these methods have a longer healing time when used alone. Thus, we combined the two methods to fulgurate the infected inner lining of the sinus after cleaning up the hair and debris, and to identify the anatomy of the pilonidal cavity in its entirety, including its branches and cavities, by video assistance; the ultimate aim was to disperse sclerosing phenol crystals for faster healing and potentially less or no recurrence. This is the first case in the literature that has been treated by combining CPA and VADA. The patient healed within less than a month, with no need for professional wound care, and was free of recurrence at 2-year follow-up.

New technologies launch novel materials; besides their performances in products, their health hazards must be tested. This applies to the lead halide perovskite CH3NH3PbI3 as well, which offers fulgurate applications in photovoltaic devices. We report the effects of CH3NH3PbI3 photovoltaic perovskites in human lung adenocarcinoma epithelial cells (A549), human dopaminergic neuroblastoma cells (SH-SY5Y) and murine primary hippocampal neurons by using multiple assays and electron microscopy studies. In cell culture media the major part of the dissolved CH3NH3PbI3 has a strong cell-type dependent effect. Hippocampal primary neurons and neuroblastoma cells suffer a massive apoptotic cell death, whereas exposure to lung epithelial cells dramatically alters the kinetics of proliferation, metabolic activity and cellular morphology without inducing noticeable cell death. Our findings underscore the critical importance of conducting further studies to investigate the effect of short and long-term exposure to CH3NH3PbI3 on health and environment.

The use of self-expandable enteral stents for palliation of malignant stenosis may present the complication of concealing the ampulla of Vater behind the metallic mesh. Anchoring in the duodenal wall (distal or partial migration) may also be a complication of biliary metallic stents and therefore may cause difficulty in gaining access to the biliary tract. In these cases of difficult access, a fenestration on the prosthesis ( biliary or enteral) can be created to allow reaching the obstructed biliary tract by means of argon plasma (AP). Were retrospectively analysed 7 cases. Under endoscopic vision, AP was directed to filgurate and cut 6 biliary prosthesis and a duodenal stent. Fulguration and cut of biliary stent was performed in 5 cases of distal partial migration and cholangitis. In one case of obstruction caused by distal migration inside the duodenal stent light, cutting of the biliary stent was performed. A window was created in the enteral prosthesis in order to access the ampulla of Vater and place a biliary tract prosthesis. All cases were resolved successfully and without complications. We conclude that the use of AP to fulgurate and cut nitinol prosthesis was effective and presented no complications in this series.

Urothelial carcinoma may occur anywhere in the urinary tract including the pendulous urethra. To prevent urethral stricture after resection and monopolor fulguration we describe the use of the holmium laser to fulgurate recurrent pTa UC from the urethra. The surgical approach was staged and provided excellent long term results for management of superficial UC.

A 2 month-old boy was admitted to the authors' hospital because of regurgitation and persistent cough during breastfeeding. A chest X-ray examination and a barium esophagogram disclosed small amounts of barium passing in the trachea, suggesting a tracheoesophageal fistula (TEF). Bronchoscopy combined with upper gastrointestinal (GI) endoscopy performed with the patient under general anesthesia confirmed the fistula. The TEF was treated by injection of 1 ml Glubran 2 from the esophageal side. A nasogastric tube was placed for feedings, and 7 days later, a barium esophagogram showed a reduction of caliber but not complete closure of the TEF. Unsuccessful fistula obliteration with Glubran was attributed to technical difficulties in catheterization of the fistula orifice, mainly resulting from its close proximity to the upper esophageal sphincter and to its small caliber. Therefore, an argon plasma coagulator (APC) probe with a circumferentially oriented nozzle was used from the esophageal side as an alternative technique to fulgurate the residual fistula orifice (see video). A nasogastric tube was placed for feedings. Oral feeding was started 7 days later when a barium esophagogram confirmed complete fistula closure. At the 2-year follow-up visit, the boy was asymptomatic, and the barium esophagogram was negative. This report describes a case in which esophagoscopy gave a clear view of the fistula due to its direction from esophagus to trachea. Complete fistula obliteration was not obtained with Glubran. However, APC was successfully used to close the residual fistula orifice. The authors suggest that APC can be used as an alternative endoscopic technique to repair TEF when other techniques fail.

- Cystic degeneration of the cerebellar tonsils in pediatric patients with Chiari Type I malformation. [Case Reports]
- JNJ Neurosurg Pediatr 2009; 4(6):557-63
- CONCLUSIONS: Cystic degeneration of the tonsils in pediatric patients with CM-I is an uncommon pathological process most likely resulting from long-standing and excessive compression. Based on their experience, the authors advocate expeditious surgical treatment, including intradural exploration and capacious duraplasty, for patients in whom there is evidence of this phenomenon on preoperative imaging.
