In selected patients, local excision of rectal cancer may be an alternative to radical surgery such as abdominoperineal excision of the rectum or anterior resection. Local excision carries lower mortality and morbidity, without the functional disturbance or alteration in body image that can be associated with radical surgery. There are several techniques of local therapy for rectal cancer, with...

Objective: Transoral laser microsurgery (TLM) for endoscopic excision of head and neck cancers of the upper aerodigestive tract has become an accepted treatment modality. As in any excision of head and neck tumors, the persistance of tumor at the surgical margins influences the outcome. One of the frequent criticisms of endoscopic resection is that the laser use makes interpretation of the surg...

BACKGROUND The list of pineal region tumors comprises an extensive array of pathological entities originating within one of the most complex areas of the intracranial cavity. With the exception of germ cell tumors, microsurgical excision is still nowadays the mainstay of management for most pineal region tumors. METHODS A search of the medical literature was conducted for publications address...

Abstract Surgical excision is the best therapeutic option for tumours in the retrorectal space. Classically, surgery in this area required an abdominal or posterior approach, or a combination of the two methods. We report the use of transanal endoscopic microsurgery for the treatment of retrorectal tumours as an alternative to classical procedures.

Ectopic odontomas are a rare disease process and need to be in the differential of the Otolaryngologist and Radiologist. Previous reports reveal the most common location to be the maxilla. We present a rare case of odontoma involving a turbinate causing nasal obstruction and foul-smelling rhinorrhea. Surgical excision is the treatment of choice with an endoscopic approach, if feasible.

Amyloidosis of the skull base is a rare entity. A patient with localized amyloidosis of the sphenoid sinus presented at our institution with cerebrospinal fluid rhinorrhoea. Endoscopic excision of the lesion and multilayered obliteration of the sphenoid sinus resolved the symptoms.

Schwannoma is a benign encapsulated tumor that originates from the Schwann cells lining nerve fibers outside the central nervous system. We report a rare case of schwannoma that arose from the left arythenoid cartilage The patient underwent excision of the mass through microlaryngeal endoscopic procedure. No recurrence was observed during follow-up.

Introduction: Teratomas are neoplastic tumors derived from totipotent germ cells containing a wide assortment of tissues originating from all three germ cell layers. Teratomas can be mature or immature depending on the presence of immature tissues; typically neuroepithelial tissue. Immature teratomas can be oncologically benign or malignant, and can be divided into three grades with increasingl...

Objective : We aimed to examine the effect of different intervals end tidal CO2 ( etCO2 ) values on hemodynamics and surgery in endoscopic endonasal transsphenoidal pituitary surgery. Material Methods: Two groups were evaluated retrospectively according maximum at time sellar resection. Group 1: 21 patients, etCO 2 =25-37 mmHg 2: 2=38-50 mmHg. The demographic characteristics, mean arterial pres...
