pelvic surgery.

Consequently, patients with previous pelvic surgery
and history of major inflammatory pelvic disease or acute cholecys-
tectomy were also excluded from the hybrid NOTES approach. So
we started offering the hybrid NOTES approach to women over
40 years old with no previous pelvic surgery or history of inflam-
matory pelvic disease. SILS was offered to male patients and women
excluded from the hybrid NOTES approach being previous surgery
in the upper right quadrant and gallbladder emphiema the main
contraindications. At our department, nine female patients met the
inclusion criteria to undergo hybrid transvaginal cholecystectomy.
However, three preferred the SILS approach because of concerns
about safety of the NOTES technique and potential for infectious
complications related to the transvaginal approach. Peterson et al.

surveyed 100 women who were given a written description of MIS
and NOTES surgery along with a 10-question survey exploring their
concerns and opinions regarding transvaginal surgery. Women have
a positive perception of transvaginal procedures and will want such
procedures if they are found to be equivalent to laparoscopic surger-
ies, but infectious were a major concern for women who would not
want transvaginal surgery as showed in our limited experience. In
conclusion, NOTES and SILS are promising techniques which need
new and dedicated instrumentations to reduce technical limitations.

Post laryngectomy speech and voice rehabilitation: past, present
and future
Speech, as a form of communication, is a vital key to human exist-
ence, giving meaning, colour and purpose to one’s life. In spite of
major strides in the field of conservative laryngeal surgery and
modalities of concurrent chemoradiation, total laryngectomy (TL)
still remains the procedure of choice for advanced-stage (Stage
T3-T4) laryngeal carcinoma around the world.
1
TL, although cura-
tive, has its own set of consequences like loss of voice, olfactory and
gustatory changes with psychosocial alterations affecting the overall
quality of life of the patient. This demands comprehensive post-
laryngectomy rehabilitation in order to bring the patient back to the
mainstream of the society.
Since the first laryngectomy more than 150 years ago, by The-
odore Billroth our efforts to provide the laryngectomee with a near
normal alaryngeal voice are still ongoing. In the past, many
researchers have made attempts to make the laryngectomee speak
‘his own voice’ but, their efforts proved futile. The ‘artificial larynx’
devised by Billroth did not stood the test of time while Kaiser’s
method of esophageal speech failed as it required a tremendous level
of proficiency and training in order to learn the method. Although,
esophageal speech was a hands-free speech and required no costly
equipments, 40 to 74% of laryngectomees failed to acquire func-
tional esophageal speech.
2
Intensity levels were 6–10 dB lower than
laryngeal speech which made noisy environments problematic for
esophageal speakers.
3
Next in succession was the electrolarynx, a
handheld device which provided useful alaryngeal voice for a small
number of laryngectomees, but here again, the significant limitations
of the mechanical, robotic quality of the voice and the need to
operate the device manually drastically limited its effectiveness.
An interesting event is described by Gussenbauer of a laryngec-
tomee who in a suicidal attempt stabbed his neck with an ice pick
and miraculously could speak.

This event generated enthusiasm
amongst the surgeons in the mid-1900s to provide surgical voice
restoration using tracheoesophageal fistula. Surgeons such as
Conley in the USA, Staffieri in Italy and Amatsu in Japan proposed
reconstructive methods that incorporated shunts of planned fistulae
to establish voice after total laryngectomy by attempting to mimic
laryngeal voicing and restore pulmonary-driven speech.
4,5
Tragi-
cally, all of these methods failed over time because the fistulae either
allowed aspiration or became too patent or stenotic. To overcome
these fistula-related problems, it was Professor Mozolewski of
Poland who conceptualized the first useful voice prosthesis in 1972.
The detailed description of the silicon one-way valve was given by
Blom and Singer in 1980, which later revolutionized the field of
post-laryngectomy voice rehabilitation.
Surgical voice restoration using voice prosthesis is based on the
concept of surgically creating a tracheoesophageal puncture which is
maintained by the silicon one-way valve. The valve transfers the
pulmonary driven air into the surgically created neo-glottis which is
set into vibration. The sound generated by the mucosal vibrations in
the neo-glottis is then articulated in the oral cavity (Fig. 1).

To
date, numerous designs of voice prosthesis have been described viz:
Blom-Singer, Provox 1 and 2, Provox Act-valve, Provox Vega,
Groningen, VoiceMaster, Nijdam and Bordeaux voice prostheses.
These prostheses mainly differ in the aspects of size, method of
insertion and the pressure required in the effort to speak either
low/high pressure. The non-indwelling devices developed earlier
