Laparoscopic fenestration of symptomatic non-parasitic cysts of the liver.

BACKGROUND: Some 5-10 per cent of patients with congenital 'solitary' liver cysts develop symptoms (pain, gastric outlet obstruction or jaundice), and require treatment. METHODS: Ten consecutive patients with symptomatic non-parasitic liver cysts have been treated by laparoscopic fenestration. RESULTS: There were no postoperative complications. During a median follow-up of 25.5 months with ultrasonographic examination there has been no recurrence of the cysts and the patients remain asymptomatic. CONCLUSION: The minimal access surgical approach by laparoscopic fenestration could become standard treatment for simple liver cysts.

Laparoscopic fenestration of symptomatic solid spleen cyst with harmonic scalpel instrument.

The treatment of two operated solid splenic cysts has been reported by authors. Laparoscopic cyst fenestration has been demonstrated to be a useful alternative method to open surgery. The aim of the authors was to analyse the use of Ultracision Harmonic Scalpel in two spleen preserving procedures. Cysts were located in the superior and the anterior-inferior pole of the spleen. Cyst wall not covered by spleen tissues was removed, drain was left in the abdomen. In the demonstrating spleen cyst operation the advantages of HS instrument was the clean operating field, correct coagulation of cyst wall, short hospital stay. Authors believe that this new technology will make it easier and more desirable for surgeons to fenestrate symptomatic spleen cysts.

[Laparoscopic fenestration of the ovaries].

The authors have performed an ovary fenestration in 220 women with primary or secondary amenorrhea. This was made with the help of instrumentation for laparoscopy and a monopolar electrodiathermic coagulator with differently shaped endings. The power supply was provided from Martin Elektrotom 2000. A spontaneous recovers of the menstruation was achieved in 36.84% of the cases as a result of the endoscopic intervention. A follows up pregnancy was achieved in 12.4% of the women. Considering the obtained results, the authors recommend the use of a laparoscopic ovary fenestration when a women with ovarian cysts is treated.

[Non-parasitic liver cysts: laparoscopic and conventional fenestration].

From 1992 till 1997 10 patients with solitary non-parasitic liver cysts were treated by laparoscopically fenestration of the cysts. The size of the cysts varied between 8 and 16 cm (median 13.5). Conversion to laparotomy was required in one patient because of intraoperative bleeding. In nine patients the laparoscopic procedure was finished successfully. In these cases we observed no intraoperative complications (9/10), intraoperative blood loss amounted up to 100 ml. Median operative time amounted to 82.5 minutes (55-155). No postoperative complications were observed. In two patients a cystadenoma was proven by postoperative histology, in both cases a liver resection was performed. During a median follow-up of 33 (2-43) months 2 of 7 patients treated with laparoscopically fenestration developed a recurrence (28%).

[Laparoscopic fenestration of lymphocele after renal transplantation: report of two cases].

Lymphocele after renal transplantation is a complication that often requires surgical treatment. We performed laparoscopic drainage for the postoperative lymphocele in two renal transplantation patients. The patients were suffering from perineal discomfort and urinary frequency due to the lymphocele after the renal transplantation. Percutaneous catheter drainages and injections of tissue sclerosing agents such as povidone-iodine solution and tetracycline were not effective. Then fenestration of the lymphocele by laparoscopic technique was done. This procedure made the lymphatic fluid free from the lymphocele in the retroperitoneal space to the peritoneal cavity following creation of a peritoneal window. There were no apparent complications. The patients were free from symptoms and had no relapse 10 months after the operation. We report the procedure and the results of the laparoscopic fenestration.

Laparoscopic fenestration in combination with ethanol sclerotherapy prevents a recurrence of symptomatic giant liver cyst.

Laparoscopic fenestration in combination with ethanol sclerotherapy of the cyst wall was performed in four patients with symptomatic giant solitary liver cyst. Two of these patients had recurrent liver cysts, which were resistant to simple laparoscopic fenestration. After the combination therapy, none of the cysts recurred during follow-up periods ranging from 11 to 33 months.

Vestibular fenestration and stapedioplasty in congenital stapes and vestibular window abnormality.

In this paper the results of vestibular fenestration and stapedioplasty in cases of congenital stapes deformity and vestibular window abnormality are presented. The problems in the surgical reconstruction of the middle ear transmission system, especially the importance of the areal ratio between the tympanic membrane and the vestibular window and the ossicular lever action, are discussed. The following conclusions were reached: 1. The area of the new vestibular window should be greater than 2.0 x 1.0 mm, i.e., one third of normal. 2. Hearing gain was about 1.5 times better after incus-stapedioplasty than after malleus-stapedioplasty. It is recommended that an effort be made to adopt incus stapedioplasty whenever possible.

Endolymphatic hydrops after fenestration: a temporal bone study with implications on the function of the utriculo-endolymphatic valve.

A temporal bone specimen demonstrating endolymphatic hydrops 13 years after fenestration of the lateral semicircular canal is presented. Fibro-osseous tissue extending from the lateral semicircular canal and reaching the vestibule produced fixation of the membranous wall of the utricle to the bony wall. Fixation and retraction of the utricule appears to have resulted in a permanently open utriculo-endolymphatic valve leaflet. Similar findings of fibro-osseous changes arising from the area of the crus commune and an open valve were found in a Meniere's disease specimen. The implications of these findings on the function of the valve are discussed.

Fenestration and occlusion of posterior semicircular canal for patients with intractable benign paroxysmal positional vertigo.

A series of 15 patients with intractable benign paroxysmal positional vertigo (BPPV) who had fenestration and occlusion of the posterior semicircular canal (FOP) surgery commencing in December 1990 are reported. Follow-up was from 14 to 40 months. All patients reported a cure of their positional vertigo. No patient regretted having the surgery. All patients had a negative Dix-Hallpike test post-operatively and the test remained negative for the duration of follow-up. Eight patients had a mild high frequency sensorineural hearing (SNHL) loss post-operatively which had almost recovered six months later. No patient reported any change in their hearing following surgery. Of the 10 patients who did not have pre-operative tinnitus, six developed tinnitus but it was not considered significant by them. All patients developed mild unsteadiness following surgery which gradually improved with mobilization and physiotherapy if necessary. The operation preserves hearing, is technically straightforward, well-tolerated and effective.

Squamous cell carcinoma of the temporal bone arising 43 years after fenestration procedure.

Squamous cell carcinoma originating in the middle ear cleft is a rare tumor that tends to be diagnosed late in its course. The presenting symptoms mimic inflammatory disease of the middle ear space, and hence biopsy is often delayed. Herein we present a case of squamous cell carcinoma of the temporal bone arising 43 years after fenestration procedure. Operative findings were significant for complete dissolution of the tegmen tympani, tegmen mastoideum, and posterior fossa dura plate with dural exposure and sigmoid sinus exposure. Tumor was noted to invade the labyrinth at the horizontal semicircular canal. This case report highlights the aggressiveness of this particular tumor in a previously exenterated mastoid cavity and its proclivity to penetrate the otic capsule via pre-formed pathways. The treatment of choice is aggressive surgical resection followed by radiotherapy.

Fenestration and occlusion of the posterior semicircular canal for benign positional vertigo.

Benign positional vertigo is a potentially disabling condition characterized by episodic vertigo following certain provocative head movements. In most patients it is self limiting; however, in a few it may prove intractable, causing considerable social morbidity. In these patients surgery may be considered. Surgery previously involved section of the vestibular or singular nerves, involving a significant risk to hearing and to the facial nerve. Ablation of the labyrinth may even be considered. The new surgical technique of occlusion of the posterior semicircular canal has proved to be curative in most patients with benign positional vertigo with little risk of hearing. This paper describes our experience of fenestration and occlusion of the posterior semicircular canal in four patients.

Split thickness flap, apically replaced, with protected linear periosteal fenestration.

The split thickness flap, apically replaced, with internal linear periosteal fenestration, is a combination of two known techniques. This procedure is another choice to solve mucogingival problems. The advantages in addition to securing a firmer bond of periosteum to bone and mucosa to periosteum at the selected position are: there is no bone exposed, healing is apparently faster and postoperative pain is minimal. An experimental work, carried out on dogs to study the histological reactions after this procedure, is in progress. The results of these observations will be reported in a future publication.

Perception of audio-frequency vibrations by profoundly deaf subjects after fenestration of the vestibular system.

A survey is given of the literature on the sensitivity of the vestibular system to audio-frequency sound and vibration in animals. It is also shown that responses to such stimuli can be evoked in man. On the basis of these results it was decided to perform a fenestration of the horizontal semicircular canal in three profoundly deaf volunteers, with normal sensitivity of the vestibular system. The first results are promising: the threshold for audio-frequency vibration in the operated ears improved markedly. Furthermore, the subjects reported perception of environmental sounds using a bone conductor hearing aid.

Window on the ear: Barbara Hepworth and the fenestration series of drawings.

In November 1943, one of Barbara Hepworth's daughters (Sarah, one of triplets) developed osteomyelitis of the thigh. This necessitated operation and subsequent treatment at the Princess Elizabeth Orthopaedic Centre in Exeter by Mr. Norman Capener. Artist and surgeon subsequently became friends and she encouraged his activities as a 'weekend sculptor'. At his invitation she came to the hospital in November 1947 watching him in out-patients but more particularly in the operating theatre; other visits to London and Exeter followed. These studies of orthopaedic procedures form the great majority of Hepworth's sixty-plus hospital drawings/paintings but there is also a small group of six paintings involving an operation on the ear made in April and May 1948. The link between these two and the introduction to the ear surgeon, Mr Garnett Passe, is unclear. Five of the paintings of the ear operation are still in circulation but there is also a sketchbook containing no fewer than 28 drawings. A selection of the sketches together with the fenestration series of paintings will be discussed and also the relationship with the surgeon, Mr Garnett Passe.

Fenestration surgery for otosclerosis: CT findings of an old surgical procedure.

Numerous attempts to deal surgically with otosclerosis were made before the current method of stapedectomy with stapes prosthesis was established. We report a case with unique CT findings of a patient who underwent fenestration surgery for otosclerosis in the early 1940s. Recognition of this old surgical procedure on the imaging scans may avoid misdiagnosis of labyrinthine fistulae or middle and inner ear malformations.

Histopathology of fenestration operation for otosclerosis.

The author describes the histopathology of fenestration operation in five temporal bones of the Massachusetts Eye and Ear Infirmary collection. The four subjects underwent the intervention more than 18 years before their death. One of the patients was operated bilaterally by Lempert himself in 1950. Special attention is given to the effect on hearing results of the otosclerotic disease; the condition of the middle ear, mastoidectomy cavity, and fenestra; and the lateral and posterior membranous semicircular canals. Also the patency of the three fenestrae (the oval, the round, and the new fenestra) in respect to the resulting hearing function, is considered.

Fenestrated sheen macular dystrophy. A new autosomal dominant maculopathy.

A new, slowly progressive, autosomal dominant macular dystrophy was found in five patients from three generations of a family, with follow-up for long as 27 years. The mild functional abnormalities of this dystrophy were roughly correlated with age; in the sixth decade of life, paracentral scotomatous areas were noted. The earliest ophthalmoscopic findings were present in a 4-year-old and consisted of a yellowish refractile sheen with red fenestrations within the sensory retina of the macula. By the third decade, an annular zone of hypopigmentation of the retinal pigment epithelium (RPE) appeared around the area of the sheen and progressively enlarged. Surrounding the annular zone of hypopigmentation and at its center was slightly hyperpigmented RPE (bull's-eye lesion). Fluorescein angiography showed no abnormalities in the sensory retina and intact perfusion of choriocapillaris.
