Fluorescence spectroscopy for diagnostic differentiation in uteri's cervix biopsies with cervical/vaginal atypical cytology.

This work aims the diagnostic differentiation of chronic inflammation (CC), low-grade Intraepithelial squamous lesions (LGSIL) and high-grade intraepithelial squamous lesions (HGSIL) in biopsies of cervix of uterus from patients with atypias (ASC-US and ASC-H) and lesions (LGSIL and HGSIL), traced in the cervical/vaginal cytology by using Laser-Induced Fluorescence Spectroscopy (LIFS), with 488 nm excitation wavelength. Ninety seven biopsies from 32 patients with atypical cervical/vaginal cytology were collected. The biopsies were guided by colposcopy and taken at the squamous-columnar junction.

Inguinodynia after two inguinal herniorrhaphy methods.

The aim of this study was to compare the rate and characteristics of postoperative neuralgia after 2 methods of inguinal hernia repairs. Between July 1997 and December 2000, 400 inguinal hernia repairs were performed and followed up in a prospective trial about postoperative nerve irritations: 200 patients with laparoscopic transabdominal hernioplasty (TAPP group), and 200 patients with tension-free hernia repair using Lichtenstein's technique (LICH group). We applied a clinic protocol of data about pain location, neuralgia characteristics, and period of time until the patient was completely pain free.

Prospective evaluation of emergency versus delayed laparoscopic cholecystectomy for early cholecystitis.

Treatment of acute cholecystitis is still under debate. The aim of this study was to evaluate the efficacy of early laparoscopic cholecystectomy (ELC) in comparison with conservative treatment followed by delayed laparoscopic cholecystectomy (DLC) in the management of acute cholecystitis. This prospective comparative study involved two groups of patients presenting with acute cholecystitis within 72 hours of the onset of symptoms.

[Effectiveness of a group therapy intervention to quit smoking. Randomized clinical trial].

Background: Group therapy is a widely used technique for the treatment of tobacco, alcohol and other toxic addictions. Nevertheless, its effectiveness for smoking cessation remains to be established. Our objective was to evaluate the relative effectiveness of a group intervention versus an individual intervention for smoking cessation.

A simple scoring system to reduce intraabdominal septic complications after laparoscopic appendectomy.

Background: The development of intraabdominal abscess (IAA) following laparoscopic appendectomy (LA) is associated with significant morbidity. The aim of the present study was to validate an IAA risk score constructed from a previous review of 156 consecutive LA.

Methods: The score was tested in 250 subsequent consecutive LA and in patients with a positive risk score.

Laparoscopic surgery for duodenal ulcer: first results of a multicenter study applying a personal procedure.

Background/aims: First results from 14 different centers applying a personal procedure for the treatment of duodenal ulcer by laparoscopic surgery.

Methodology: One hundred and thirty-six patients were operated on in 14 surgical centers between January 1991 and February 1995. All patients underwent posterior truncal vagotomy (PTV) and anterior linear gastrectomy (ALG) for chronic duodenal ulcer.

Laparoscopic surgery for duodenal ulcer: first results of a multicentre study applying a personal procedure.

Between January 1991 and February 1995 data were gathered on 136 patients operated on in 14 surgical centres. All patients underwent posterior truncal vagotomy (PTV) and anterior linear gastrectomy (ALG) for chronic duodenal ulcer. Recurrence and repeated bleeding were the main indications for surgery.
