INTRODUCTION: Laparoscopic management of giant hydatid cyst has limitations such as spillage, poor control, difficulties in suctioning the contents through special ports which are not easily available, difficulty in the obliteration of residual cavity and recurrence. We describe single-incision trocar-less endoscopic (SITE) technique which simplifies enucleation and management of residual cavity. METHOD: Inclusion criteria for these cases were patients having single uncomplicated giant hydatid cyst >5 cm present at the surface of the liver and palpable on clinical examination...

BACKGROUND: Submucosal tunneling endoscopic resection (STER) is regarded as a promising method for resection of submucosal tumors (SMTs); however, little is known about a comprehensive comparison of STER and thoracoscopic enucleation (TE). The aim of this study is to compare the clinical outcomes of STER and TE for large symptomatic SMTs in the esophagus and the esophagogastric junction (EGJ), as well as to analyze the factors that affect the feasibility and safety of STER. STUDY DESIGN: We enrolled 166 patients with large symptomatic SMTs in the esophagus and the EGJ from September 2011 and March 2016 in this retrospective study...

Purpose: In retinoblastoma, adjuvant chemotherapy after enucleation is given in eyes with histopathological high-risk features (HRFs) to reduced mortality. Anterior chamber seeds (AC seeds) on histopathological evaluation are a contentious finding. This study attempts to determine the effect of AC seeds on the survival rate. Methods: This is a retrospective case record review. Eyes were divided into four groups: those with neither AC seeds nor HRFs, those with only HRFs, those with only AC seeds, and those with both HRFs and AC seeds...

PURPOSE: To test the hypothesis that delayed dark adaptation in patients with macular degeneration is due to an excess of free unliganded opsin (apo-opsin) and a deficiency of the visual chromophore, 11-cis retinal, in rod outer segments. METHODS: A total of 50 human autopsy eyes were harvested from donors with and without macular degeneration within 2-24 hrs. postmortem. Protocols were developed which permitted dark adaptation of normal human eyes after death and enucleation...

OBJECTIVES: Pleomorphic adenomas and Warthin tumors are the most common salivary gland tumors. It is important to differentiate between them because at least a partial parotidectomy is necessary for pleomorphic adenomas, whereas enucleation is sufficient for Warthin tumors. This study aimed to evaluate the usefulness of vascular pattern analysis using microvascular sonography to differentiate between the tumors. METHODS: Sixty-two patients with pathologically proven pleomorphic adenomas (nā€‰=ā€‰38) and Warthin tumors (nā€‰=ā€‰24) were included...

We present the case of a 56-year-old man who developed a neoplasm of epithelioid histology in his anophthalmic left orbit 21 years after he underwent enucleation for a spindle cell iris melanoma. The recurrent tumour was managed by orbital exenteration. Neither further recurrence nor metastasis was diagnosed over a 5-year follow-up period. This case, along with five other similar cases in the literature,(1-3) emphasises the importance of long-term follow-up after treatment of iris melanoma.

Gastrointestinal stromal tumors (GIST) are the most common type of gastrointestinal mesenchymal tumor, but are rarely found in the thoracic esophagus. There is no clear consensus about the optimal treatment of this rare disease. A systematic search of the literature was performed for localized esophageal GIST that was resected between 2000 and 2015, and individual patients were included from two major academic institutions. We obtained information on demographics, tumor size and location, mitotic rate, treatment method, and time to recurrence or death...

Ovine somatic cell nuclear transfer (SCNT) efficiency remains lower. Therefore, we optimized the program before oocyte enucleation on ovine SCNT. Four experiments were done including exposure duration of ovaries (3 h or 3 to 5 h), duration of oocytes maturation (18 h and 24 h), rate of donor adherent and enucleation time of maturate oocyte. The maturation rates of oocyte, fusion rates and cleavation rates of cloned embryos were used to assess the efficiency of different procedures. The maturation rates of ovaries with 3 h exposure was higher than that of 3 to 5 h (60...

PURPOSE: Typically treatment of large melanomas (by Collaborative Ocular Melanoma Study criteria) is restricted to enucleation, due to size constraints for plaque brachytherapy. Because primary and metastatic uveal melanoma cells are inhibited by bevacizumab (an anti-vascular endothelial growth factor), this prospective study evaluated the impact of intravitreal bevacizumab on large uveal melanomas that were destined for enucleation. Size reduction by bevacizumab would potentially salvage these eyes by making them eligible for treatment with plaque brachytherapy...
