Telementoring. A practical option in surgical training.

BACKGROUND: Telemedicine offers significant advantages in bringing consulting support to distant colleagues. There is a shortage of surgeons trained in performing advanced laparoscopic operations. AIM: Our aim was to evaluate the role of telementoring in the training of advanced laparoscopic surgical procedures. METHODS: Student surgeons received a uniform training format to enhance their laparoscopic skills and intracorporeal suturing techniques and specific procedural training in laparoscopic colonic resections and Nissen fundoplication. Subsequently, operating rooms were equipped with three cameras. Telestrator (teleguidance device), instant replay (to critique errors), and CD-ROM programs (to provide information of reference) were used as intraoperative educational assistance tools. In phase I, four colonic resections were performed with the mentor in the operating room (group A) and four colonic resections were performed with the mentor on the hospital grounds, but not in the operating room (group B). The voice and video signals were received at the mentor's location, using coaxial cable. In phase II, two Nissen fundoplications were performed with the mentors in the operating room (group C) and two Nissen fundoplications were performed with the mentors positioned five miles away from the operating room (group D), using currently existing land lines at the T-1 level. RESULTS: There were no differences in the performances of the surgeons and outcome of the operations between groups A & B and C & D. It was possible to tackle the intraoperative problems effectively. CONCLUSIONS: The telementoring concept is potentially a safe and cost-effective option for advanced training in laparoscopic operations. Further investigation is necessary before routine transcontinental patient applications are attempted.

Tuberculous peritonitis--do not miss it.

UNLABELLED: Incidence of tuberculosis is sharply rising in the United States, and tuberculous peritonitis is often diagnosed late in the course of the disease, resulting in undue patient morbidity and mortality. PURPOSE: Purpose of this study was to better identify which clinical, laboratory, radiologic, and invasive procedures were most useful in diagnosing tuberculous peritonitis. METHODS: All cases of tuberculous peritonitis diagnosed between 1982 and 1994 were reviewed retrospectively to discern which laboratory, radiographic, and procedural tests were helpful in diagnosing the condition. RESULTS: Twenty-eight cases of tuberculous peritonitis were diagnosed during the studied period. Two patients were not diagnosed until autopsy. Patients from all socioeconomic classes and multiple races ranged in age from 3 to 69 (mean, 29.5) years. Most patients presented with a chronic wasting illness, mild abdominal pain, and fever. Purified protein derivative was only positive in 5 of 16 patients. Chest radiographs were suggestive of pulmonary tuberculosis (TB) in five patients. Ultrasound examination of the abdomen was helpful in five patients, and computed tomographic scan was suspicious in 16 of 17 patients. Sputum for acid fast bacillus (AFB) smear was positive in 3 of 14 patients, and paracentesis for AFB smear was positive in 1 of 8 patients. Routine blood work was not helpful. Laparoscopy was diagnostic in five of seven patients. Laparotomy and tissue biopsy of characteristic tissue for AFB smear and culture was diagnostic in 20 of 20 patients. Once diagnosed, all patients responded rapidly to empiric antituberculous medical therapy, except one patient with miliary TB who died shortly after diagnosis. A trend in earlier diagnosis was noted in recent years and is felt to be the result of an elevated index of suspicion. CONCLUSIONS: TB peritonitis may be fatal but is medically cured if diagnosed in a timely fashion. It is essential that the clinician suspect the disease in appropriate patients. Tests frequently associated with TB such as chest radiograph and purified protein derivative are not sensitive in detection of TB peritonitis. Computed tomographic scan is the most useful radiographic study. Mini laparotomy with tissue biopsy for smear and culture is the most sensitive and specific diagnostic procedure.
