OBJECTIVE To assess our outcomes after minimally invasive esophagectomy (MIE). SUMMARY BACKGROUND DATA Esophagectomy has traditionally been performed by open methods. Results from most series include mortality rates in excess of 5% and hospital stays frequently greater than 10 days. MIE has the potential to improve these results, but only a few small(More)
BACKGROUND Local recurrence is a major concern after sublobar resection (SR) of non-small cell lung cancer (NSCLC). We postulate that a large proportion of local recurrence is related to inadequate resection margins. This report analyzes local recurrence after SR of stage I NSCLC. Stratification based on distance of the tumor (<1 cm vs >or=1 cm) to the(More)
OBJECTIVE Treatment options for patients with non-small cell lung cancer who are not surgical candidates or who refuse operation are limited. Radiofrequency ablation represents a potential less invasive option for these patients. Our initial experience with radiofrequency ablation for peripheral, primary non-small cell lung cancer is reported. METHODS We(More)
BACKGROUND This study evaluated the 2-year overall survival rate, adverse event rate, local control rate, and impact on pulmonary function tests for medically inoperable patients with stage IA non-small cell lung cancer (NSCLC) undergoing computed tomography (CT)-guided radiofrequency ablation (RFA) in a prospective, multicenter trial. METHODS Fifty-four(More)
OBJECTIVE The purpose of the present study was to compare the selection criteria and short-term outcomes among 3 prospective clinical trials using stereotactic body radiotherapy (Radiation Therapy Oncology Group [RTOG] trial 0236), sublobar resection (American College of Surgeons Oncology Group [ACOSOG] trial Z4032), and radiofrequency ablation (ACOSOG(More)
OBJECTIVE Surgical resection is the standard of care for stage I non-small cell lung cancer. The objective of this study was to evaluate computed tomography-guided radiofrequency ablation as an alternative treatment option for high-risk patients with stage I non-small lung cancer. METHODS Patients with medically inoperable stage I non-small lung cancer(More)
BACKGROUND AND OBJECTIVES Gastroesophageal reflux disease (GERD) is commonly associated with morbid obesity (MO). Antireflux surgery has a higher failure rate in MO and addresses only one of the comorbidities present. This paper reviews the results of laparoscopic Roux-en-Y gastric bypass (LRYGBP) performed for recalcitrant GERD in MO. METHODS Patients(More)
This paper describes a method to recognize off-line handwritten Sinhala characters, the language used by the majority of Sri Lanka. The classification approach is based on discrete hidden Markov models. A subset of the Sinhala alphabet was chosen for the study. The unknown characters are first pre-classified into one of three character groups, based on the(More)
This article presents a database of images of handwritten city names. The aim is to provide a standard database for Sinhala handwriting recognition research. This database contains about 15,000 images of about 500 city names of Sri Lanka. These images are obtained from the addresses of live mail so that the writers had no idea that they would be used for(More)
