Purpose: The objective of this randomized in-vitro study was to compare the suturation time, integrity, and quality of the bladder closure in fresh cadaver pig bladders performed with barbed polyglyconate sutures vs polyglactin 910 sutures in running and interrupted fashion. Materials and Methods: Forty-eight pig bladders, each weighing from 120 to 150 g, were randomly divided into three groups: Group 1 (interrupted polyglactin 910 suture group), group 2 (running polyglactin 910 suture group), and group 3 (running barbed polyglyconate suture group). The bladder defects were closed laparoscopically, and the suturation times were noted. Two surgeons evaluated the integrity of each bladder closure. A cystometry was performed, and the filling and leak pressures were noted. A Kruskal-Wallis variance analysis test was used to compare the results of the three groups, and P<0.05 was considered significant. Results: There was a statistically significant difference between the mean suturation times of three groups: Group 1, 15.2 minutes; group 2, 9.14 minutes; and group 3, 7.13 minutes (P<0.05). Mean bladder capacity at the time of leakage was 276.2, 353.8, and 419.7 mL for groups 1, 2, and 3, respectively, and the difference was statistically significant (P<0.05). Conclusion: For the first time, we demonstrated laparoscopic knotless closure of bladder defects using the barbed polyglyconate suture material in an experimental in-vitro model. Closing the pig bladder with running knotless barbed suture provides a more effective and faster watertight bladder closure than traditional polyglactin 910 suture material. © Copyright 2012, Mary Ann Liebert, Inc. 2012.

It is well known that basaloid squamous call carcinoma (BSCC) is more aggressive than the usual form of squamous cell carcinoma. However, current information about the prognostic significance of basaloid squamous cell carcinoma in the larynx is sparse. We investigated p63, p53 and Ki67 in BSCC of the larynx. In a retrospective study conducted from January 2000 to June 2006, we used immunohistochemistry to analyse the protein expression of p63, p53, and Ki-67 in paraffin-embedded tumour samples from 22 BSCC patients and compared the clinicopathological parameters with the survival outcome. Positive p63 expression was found in 16 of 22 BSCC specimens (72.7%). Expression was higher in cases without lymph node metastasis than in cases with lymph node metastasis. This investigation found an inverse correlation between the expression of p63 and lymph node status in BSCC. To our knowledge, this is the first clinical study of p63 expression in laryngeal BSCC.

We evaluated the technique of laryngofissure cordectomy without tracheotomy in patients with T1a laryngeal carcinoma. Twelve male patients (mean age 55 years; range 47 to 68 years) who were diagnosed with T1a laryngeal carcinoma and treated with cordectomy without tracheotomy between January 2005 and March 2008 in our clinic were evaluated with retrospective review of medical charts. They were all treated with laryngofissure and cordectomy. The cord with carcinoma was excised with the inner perichondrium of thyroid cartilage and surgical margins were examined hystopatologically with frozen section. Postoperative oncologic and functional results were evaluated. None of the patients were treated with preoperative or postoperative tracheotomy. Oral nutrition was initiated on the 3rd postoperative day and the patients were discharged. No tumor recurrences were seen in the postoperative follow-ups. Although the surgical area is slightly restricted due to the use of entubation tube, cordectomy without tracheotomy had better functional results and the oncological results were unchanged compared to cordectomy with tracheotomy. Since the procedure is without tracheotomy, psychological adaptation period of the patients was shorter compared to the patients treated cordectomies with tracheotomy. Source

Introduction: Oesophageal heterotopic gastric mucosa mostly presents in the upper part of the oesophagus. It is commonly under-diagnosed because of its localisation. Aim: To expose the association between heterotopic gastric mucosa and endoscopic features of the upper gastrointestinal tract. Material and methods: A total of 1860 upper endoscopic examinations performed between January 2012 and July 2013 were analysed retrospectively. Endoscopic features and histological examinations of 12 heterotopic gastric mucosa (HGM) of the upper oesophagus were documented and evaluated retrospectively. Results: There were 7 (58%) male and 5 (42%) female patients aged between 22 and 80 years with a mean age of 43.2 years. Heterotopic gastric mucosa was present in 12 (0.6%) of all patients. We were able to perform biopsy for histopathological observation on 8 (66%) of the 12 patients in which HGM was seen during endoscopy. Five (42%) patients with heterotopic gastric mucosa had oesophagitis. Los Angeles Grade A oesophagitis was found in all patients, and histologically proven Barrett's oesophagus was detected in only one patient. Conclusions: When a patient has ongoing dyspeptic complaints and reflux symptoms despite the treatment, one should be careful about possible HGM during upper gastrointestinal endoscopy. The point to be taken into consideration for patients who have metaplasia or dysplasia within HGM may need to be considered for surveillance. Source

Background: The aim of this study was to describe a new experimental perforator-based flap in rats, supplied by lateral thoracic artery perforator. Methods: Through out the study, two control and two experimental groups were created consisting of six rats in each group In the first control group (group 1), mid-axillary line and the fourth intercostal space intersection were used as the center of the flap A 3 × 2 cm flap was designed and elevated above the cutaneous maximus muscle by transecting all connections with the muscle. In the second control group (group 2), the flap was extended caudally, and 3 × 6 cm flap was designed. Then, the flap was elevated in the same manner as it was described for group 1. In the first experimental group (group 3) 3 × 2 cm flap and in the second experimental group (group 4) 3 × 6 cm flap were designed like control groups. The flaps were islanded on a single musculocutan perforator arising from lateral thoracic artery. The surviving skin paddle areas were calculated on postoperative day 7. Results: The flap viability was calculated 0% for control groups (groups 1 and 2), 100% for the first experimental group (group 3), between 33.3% and 37.7% for the second experimental group (group 4; mean ± standard deviation, 34.76% ± 1.92%). Conclusions: This new lateral thoracic artery perforator-based flap has a constant anatomy and reliable survival pattern. Also, easy harvesting and the possibility of designing two flaps per animal make this new flap an appealing model for pathophysiological or pharmacologic researches. © 2015 Elsevier Inc. Source
