Twelve patients with benign and malignant esophageal diseases were treated by transhiatal esophagectomy, without thoracotomy, using abdominal-mediastinal dissection conducted by videolaparoscopy. A cervical approach was used to retrieve the esophagus and to perform the esophagogastric anastomosis. The procedure was indicated in patients with advanced achalasia of the esophagus, severe reflux stenosis, squamous cell carcinoma, and adenocarcinoma of the esophagus. Three pleural perforations occurred during surgery. Blood loss was minimal. One patient required conversion to open surgery, two patients were submitted to chest drainage, and three had transitory dysphonia. One patient had an anastomotic leak with subsequent stenosis requiring endoscopic dilatation. No mortality occurred in this small series.

Dysphagia is related to the impairment of food passage from the mouth to the stomach. Globus pharyngis implies the frequent and often painful sensation of a lump in the throat that usually does not interfere with swallowing and may even be relieved by food intake. The diagnosis is based upon a careful history, clinical examination, endoscopy, dynamic imaging (videofluoroscopy, cinematography, videosonography) and electrophysiologic procedures (including pharyngoesophageal manometry, electromyography and pH determinations). Structural lesions of the cervical spine such as diffuse idiopathic skeletal hyperostosis are rare causes of dysphagia. Dysphagia following anterior cervical fusion as well as globus and dysphonia due to dysfunction of the vertebral joints are more likely. Symptoms with swallowing fluids indicate a neurogenic origin. Dyscoordinated swallowing, nasal reflux, dysphonia or general weakness may also occur. Chronic aspiration with respiratory compromize is the main consequence in a variety of neurological disorders as well as in cases of postsurgical dysphagia. Relaxation of the upper esophageal sphincter indicates coordinated muscle movement between the pharynx and esophagus. Dysfunction of the pharyngoesophageal segment may lead to cricopharyngeal achalasia. A dyskinetic sphincter commonly represents an extrapharyngeal cause: i.e., disease associated with gastroesophageal reflux. Disorders of the esophageal phase of deglutition can produce retrosternal pain, heartburn, regurgitation and vomiting, as well as laryngeal and respiratory signs. Esophageal motility disorders include lower achalasia, tumors, peptic strictures, inflammatory diseases, drug-induced ulcers, rings and webs. Motility disorders present with aperistaltic, spontaneous contractions, diffuse esophagospasm, or a hypermotile esophagus. Gastroesophageal reflux with esophagitis must always be excluded, especially in patients with a globus sensation. The multiple features of the appearance of the symptoms of dysphagia and globus makes multidisciplinary approach necessary in order to establish a diagnosis and begin effective treatment.

The role of botulinum toxin as a therapeutic agent is expanding rapidly in otolaryngology. Botulinum toxin is a protease that blocks the release of acetylcholine from nerve terminals. Its effects are transient and nondestructive, and largely limited to the area in which it is administered. These effects are also graded according to dose, allowing for individualized treatment of patients and disorders. Botulinum toxin has been used primarily to treat disorders of excessive or inappropriate muscle contraction. In the field of otolaryngology, these include spasmodic dysphonia, oromandibular dystonia, and blepharospasm; vocal tics and stuttering; cricopharyngeal achalasia; various tremors and tics; hemifacial spasm; temporomandibular joint disorders; and a number of cosmetic applications. Botulinum toxin treatment has recently begun to show some benefit in the control of pain from migraine and tension headache. It may also prove useful in the control of autonomic dysfunction, as in Frey syndrome, sialorrhea, and rhinorrhea. In over 20 years of use in humans, botulinum toxin has accumulated a considerable safety record, and in many cases represents relief for thousands of patients unaided by other therapy.

Botulinum toxin is a dreaded biological toxin elaborated by Clostridium botulinum. The action of this toxin is to cause paralysis of both voluntary and involuntary muscles. The unique property of paralysing capability of muscles has been used for the benefit of human beings. Dr Allan Scot, an ophthalmologist, first used the toxin in a patient with squint in 1981 and since then the botulinum toxin is being used in various disorders characterised by muscle overactivity such as spasticity in both children and adult, dystonic conditions such as blepharospasm, cervical dystonia, spasmodic dysphonia, writer's cramp, etc, hemifacial spasm and headache. Its main action is at the terminal nerve endings of myoneural junction and it prevents release of acetylcholine from vesicles thus causing chemical denervation. Its action persists for 3 to 4 months on an average. Its side effects such as drooping, diplopia, dysphagia, depending on the sites of injection, are few and usually transient. Generalised anaphylaxis is almost unknown. Now botulinum toxin is being used in non-neurological conditions where muscles are under spasmodic state such as achalasia cardia, anal fissure, spasm of urethral sphincter, etc. Because of wider safety range and fewer complications, botulinum toxin has been an important therapeutic armamentarium in different branches of medicine and surgery.

Since its introduction in the late 1970s for the treatment of strabismus and blepharospasm, botulinum toxin (BoNT) has been increasingly used in the interventional treatment of several other disorders characterized by excessive or inappropriate muscle contractions. The use of this pluripotential agent has extended to a plethora of conditions including: focal dystonia; spasticity; inappropriate contraction in most sphincters of the body such as those associated with spasmodic dysphonia, esophageal achalasia, chronic anal fissure, and vaginismus; eye movement disorders; other hyperkinetic disorders including tics and tremors; autonomic disorders such as hyperhidrosis; genitourinary disorders such as overactive and neurogenic bladder, non-bacterial prostatitis and benign prostatic hyperplasia; and aesthetically undesirable hyperfunctional facial lines. In addition, BoNT is being investigated for the control of the pain, and for the management of tension or migraine headaches and myofascial pain syndrome. BoNT injections have several advantages over drugs and surgical therapies in the management of intractable or chronic disease. Systemic pharmacologic effects are rare; permanent destruction of tissue does not occur. Graded degrees of relaxation may be achieved by varying the dose injected; most adverse effects are transient. Finally, patient acceptance is high. In this paper, clinical experience over the last years with BoNT in urological impaired patients will be illustrated. Moreover, this paper presents current data on the use of BoNT to treat pelvic floor disorders.

Among the ailments of the ocular region, the use of botulin has become established in the treatment of blepharospasm and hemifacial spasm in Finland. Botulin has also been used successfully after peripheral facial palsy to improve facial symmetry, reduce lachrymal flow, treat dribbling of saliva as well as spasmodic dysphonia of laryngeal muscles. It may be effective in dysphagia caused by tightness of the upper esophageal sphincter or in several dyshidroses. Gastroenterologic indications include anal fissure and spasm and achalasia of the lower esophageal sphincter. In urology, botulin is effective in overactive bladder and incomplete voiding.
