[Fecal incontinence and rectal prolapse. Clinico-functional assessment].

Rectal Prolapse is a rare and distressing condition, with a multifactorial etiopathogenesis. Often, this pathology is associated with fecal incontinence. The recommended approach to the patient with rectal prolapse and fecal incontinence is to repair the prolapse first, then deal particularly with fecal incontinence at a second operation. A retrospective, clinical and manometric study has varying degrees of fecal incontinence. Clinically five of their operation, and a further three patients improved, in two patients the degree of fecal incontinence remained invariable. One patient was worsened after surgery. Manometrically resting and pressure (RAP) was significantly higher in continent patients than in voluntary contraction pressure (MVCP) (p < 0.05) in preoperative testing. Postoperatively, there was a significant increase in the resting anal pressure as well as in maximum voluntary contraction pressure. Patients who remained incontinent had a significantly lower RAP and MVCP than patients who improved our regained continence. In conclusion this study shows an alteration of internal and external sphincteric function in patients with rectal prolapse. The surgical treatment of this disease improves sphincteric function. Incontinent patients with RAP < 10 mmHg and MCVP < 20 mmHg, probably they would be better treated simultaneously either for rectal prolapsus and incontinence. In this kind of patients the perianal proctectomy with total sphincteroplasty could be the elective treatment.

[Role of the anterior resection in the surgical treatment of rectal cancer. Review of the literature].

In the surgical treatment of rectal cancer, local recurrence has a high incidence up to 40% of cases. The introduction of stapling techniques permit the execution of conservative surgery with increasing frequency, to which are wrongly associated a major rate of local recurrence. In effect in the localization of midrectal cancer, at the same stage, the abdominoperineal resection and the anterior low resection have the same long term results. Residual disease is due to no removing lymphatic perivisceral tissue (mesorectum, pelvic lymphatic cell tissue), when is respected a distal clearance from the tumour's margin of 2 cm. The authors on the base of their experience and reported data, examine pathogenetic factors responsible for local recurrence and curative surgical principles. Anterior resection remains the elective operation in midrectal cancer when it is realized with completely removal of mesorectum and with "en bloc" abdominopelvic lymphadenectomy in selected cases. In Duke's C-D stages the preservation of sphincters is always to be preferred, because abdominoperineal resection doesn't assure a curative result with a better quality of life in low anterior resection.

Radial manometric study of the anal canal: preliminary results.

The pressure profile of the anal canal results from the effects of several muscles mainly the internal and external anal sphincter and the puborectalis. The preliminary results of radial manometric study of the anal canal carried out in 36 healthy volunteers, are reported. Based on the obtained results it is concluded that the anal canal shows a statistically significant difference in the radial distribution of pressure. The anatomo-physiologic mechanisms underlying this phenomenon, are discussed.

Drainage in thyroid surgery: a prospective randomised clinical study.

Drainage in thyroid surgery is still an area of controversy. We analysed the results of a prospective randomised trial conducted in our institution in order to assess the utility of drainage after thyroid surgery. Sixty patients were entered into the study, thirty of whom were drained after surgery and thirty who received no drainage. The two groups were well matched with regard to most characteristics. There was no difference between the two groups in terms of early or late postoperative complications. We therefore conclude that, in our experience, drainage after uncomplicated thyroid surgery is of no benefit.

[The right inferior laryngeal nerve with a non-recurrent course].

Two cases of a right non-recurrent laryngeal nerve were encountered during the performance of 992 thyroid operations. In its abnormal non-recurrent course the nerve passes transversely from under the carotid sheat hand takes a position which is at right-angles to the normal recurrent laryngeal nerve.
