Effects of laser reflex therapy on a motor function of the gall bladder and physical properties of bile in patients with chronic acalculous cholecystitis

Abstract Title: [Effects of laser reflex therapy on a motor function of the gall bladder and physical properties of bile in patients with chronic acalculous cholecystitis]. Abstract Source: Ter Arkh. 2009;81(2):57-61. PMID: 19334492 Abstract Author(s): N M Burduli, L G Raniuk Abstract: AIM: To study effects of laser puncture in combined treatment of chronic non-calculous cholecystitis on motor function of the gallbladder, bile physical characteristics and clinical symptoms. MATERIAL AND METHODS: 73 patients with chronic non-calculous cholecystitis were divided into two groups: 35 patients received standard therapy alone (control group) and 38 patients were exposed to laser puncture as a component of combined treatment. RESULTS: Laser radiation on acupuncture points has a positive therapeutic result, i.e. shorter clinical symptoms, correction of motor function of the gallbladder and bile physical characteristics. CONCLUSION: Laser puncture is an effective method of acalculous cholecystitis treatment and can be included in relevant combined schemes.   Article Published Date : Jan 01, 2009

Novel laser positioning navigation to aid puncture during percutaneous nephrolithotomy: a preliminary report.

World J Urol. 2018 Sep 20;: Authors: Wu J, Zhou P, Luo X, Hao Z, Lu C, Zhang H, Zhou T, Xu S Abstract PURPOSE: Accurate puncture of the renal collecting system is crucial to the success of percutaneous nephrolithotomy and presents a technical challenge for urologists. Here, we introduced the Surgical Approach Visualization and Navigation (SAVN) system, a novel navigation system to assist puncture and reduce intraoperative radiation. MATERIALS AND METHODS: Twenty kidneys of 10 cadavers were randomly divided into two groups for renal calyx puncture. In the control group, traditional fluoroscopy was used for guidance, while SAVN system was used in the experimental group. Puncture duration, number of puncture attempts, total number of intraoperative fluoroscopies, and number of fluoroscopies during the puncture procedure were recorded. RESULTS: The puncture duration was 14.2 ± 2.5 s in SAVN group and 48.3 ± 7.1 s in conventional group (P < 0.05). One puncture attempt was needed for successful puncture in SAVN group, while more than one in conventional group (P = 0.28). The total number of intraoperative fluoroscopies was 3.3 ± 1.0 in SAVN group and 14.5 ± 3.1 in control group (P < 0.05),while the number of fluoroscopies during the puncture procedure was 0 and 11.2 ± 2.4, respectively (P < 0.05). CONCLUSIONS: The novel SAVN system has a simplified structure and is easy to use. It can be used to successfully assist with puncture of the renal calyx, thus reducing puncture duration and radiation dose. PMID: 30238400 [PubMed - as supplied by publisher]

Laryngeal recurrence sites in patients previously treated with transoral laser microsurgery for squamous cell carcinoma.

Related Articles Laryngeal recurrence sites in patients previously treated with transoral laser microsurgery for squamous cell carcinoma. J Otolaryngol Head Neck Surg. 2018 Feb 13;47(1):14 Authors: Horwich P, Rigby MH, MacKay C, Melong J, Williams B, Bullock M, Hart R, Trites J, Taylor SM Abstract BACKGROUND: The laryngeal framework provides a natural barrier preventing tumour spread to extralaryngeal structures. Transoral laser microsurgery (TLM) for laryngeal squamous cell carcinoma (SCC) may violate these boundaries, altering the pathways of tumor spread for potential recurrences. Our project objective is to describe laryngeal SCC recurrence patterns and overall survival in patients requiring total laryngectomy (TL) after TLM. METHODS: Patients undergoing TLM for laryngeal SCC requiring salvage TL were identified from a prospective CO2 laser database containing all patients undergoing TLM for head and neck malignancies at the QEII Health Sciences Center in Halifax, Nova Scotia between March 2002 - May 2014. Surgical pathology reports were analyzed for tumor characteristics, extent of recurrence and invasion of local structures. Kaplan-Meier analyses were performed to evaluate overall survival, disease specific survival (DSS) and locoregional control. RESULTS: Fifteen patients were identified from the database as receiving salvage TL for recurrent disease after initial TLM resection for laryngeal SCC. Final pathology reports demonstrated that 67% (10/15) of patients had thyroid cartilage involvement while 53% (9/15) of patients had cricoid cartilage involvement on salvage TL pathology. 33% (5/15) of patients had perineural invasion and 27% (4/15) had lymphovascular invasion. Mean and median follow-up times were 36.7 months and 26.8 months respectively (range 3.9-112.6). The Kaplan-Meier estimate for overall survival at 36 months was 40% post TL with a standard error (SE) of 13.6%. DSS was 47% (SE 14.2%), and locoregional control was 55% (SE 14.5%) post TL. CONCLUSIONS: Laryngeal recurrence sites following TLM seem to be consistent with historical data at known laryngeal sites of vulnerability. Treatment with TLM does not predispose patients to a lower rate of locoregional control and overall survival after total laryngectomy and salvage outcomes are consistent with literature values.
