Digital recording of surgical procedures using a personal computer.

OBJECTIVE: To develop a system for recording surgical procedure digitally using a personal computer with real-time compression of the video signal. STUDY DESIGN: We built the system around a modern personal computer with a large hard disk to allow recording of over 250 h of continuous surgery. Digital capture from the camera was achieved using a standard external analogue-digital converter linked to the computer via a firewire cable. The software for capturing, compressing and editing movie files were obtained free of charge from the internet. The optimal settings for the software was determined. RESULTS: We have successfully used this system to record over 100 major and minor hysteroscopic, laparoscopic, vaginal and open gynaecological. Despite compression, the quality of the movies was judged to be very good and still images excellent. The recordings could be integrated in to standard presentation. Still pictures could be printed to provide hard copies for patients and medical notes, and movies burnt on to CDs or DVDs. CONCLUSIONS: A digital recording system built around a standard personal computer is relatively cheap, versatile and has a huge capacity to record surgical procedures.

Chronic ectopic pregnancy diagnosed incidentally in an infertile woman: a case report.

BACKGROUND: Chronic ectopic pregnancy is an enigma. The clinical presentation can be mild, with absent or subtle symptoms. The high incidence of negative pregnancy tests and the poor specificity of sonographic patterns can be misleading, and the correct diagnosis is sometimes established only at surgery or even histopathologically after the operation. We report the first case of a woman who was accidentally diagnosed with chronic ectopic pregnancy during diagnostic laparoscopy performed as part of a routine investigation for primary infertility. CASE: A 28-year-old woman underwent laparoscopyfor infertility. She had a regular menstrual cycle and was asymptomatic. She gave a history of a possible but unconfirmed miscarriage earlier. Her hormone profile was normal apart from a slightly raised prolactin level. An earlier ultrasound showed a polycystic appearance of the ovaries. Laparoscopy was done on the 25th day of the menstrual cycle, and beta-human chorionic gonadotropin was negative. At laparoscopy, a 2-cm mass wasfound in the right fallopian tube. There was no free blood in the pelvis, and no adhesions. Both tubes were patent at hydrotubation. The mass was excised laparoscopically, and histology confirmed a diagnosis of chronic ectopic pregnancy. CONCLUSION: A review of articles on chronic ectopic pregnancy confirmed the difficulty in diagnosing this condition preoperatively.

Endometriosis arising during estrogen and testosterone treatment 17 years after abdominal hysterectomy: a case report.

OBJECTIVE: To report the possible association between the use of oestrogen replacement therapy and endometriosis in a postmenopausal woman. METHODS: We present a case of a postmenopausal, previously hysterectomised, woman who received hormonal replacement therapy and developed a large broad ligament cyst. Two years prior to her presentation she had been complaining of pelvic pain and deep dyspareunia. RESULTS: Pelvic ultrasound showed an adnexal cyst that was increasing in size. CA-125 was normal. Laparoscopy revealed multiple endometriotic deposits and a broad ligament cyst. Cystectomy and oophorectomy were done. Histology confirmed a diagnosis of endometriosis including the broad ligament cyst. CONCLUSIONS: Hormonal replacement therapy can be associated with de novo endometriosis including at sites, which are unusual.

Effectiveness of auto-cross-linked hyaluronic acid gel in the prevention of intrauterine adhesions after hysteroscopic adhesiolysis: a prospective, randomized, controlled study.

BACKGROUND: A prospective, randomized, controlled study was performed to assess the efficacy of auto-cross-linked hyaluronic acid (ACP) gel in preventing the development of intrauterine adhesions following hysteroscopic adhesiolysis. METHODS: Ninety-two patients with irregular menses and intrauterine adhesions referred to the Hysteroscopic Unit of the University of Naples "Federico II". Patients were randomized to two different groups. Group A were randomized to hysteroscopic adhesiolysis plus intrauterine application of ACP gel (10 ml) and group B were randomized to operative hysteroscopy alone (control group). Baseline adhesion scores were calculated for each patient and at 3 months after surgery. RESULTS: Group A showed a significant decrease in intrauterine adhesions at 3 months follow-up in comparison with the control group. Staging of adhesions showed a significant decrease in adhesion severity in patients treated with ACP gel. CONCLUSIONS: ACP gel significantly reduces the development of intrauterine adhesions postoperatively and its use is likely to be associated with a reduction of severe adhesions.
