Integration of quality programs by telemedicine in surgical services.

Surgical procedures can be performed and monitored in operating rooms physically isolated, but electronically linked to a parent medical center, and certainly from distant consultation. Quality of surgical care has been measured in retrospect rather than in real time, and outcomes have generally not had the benefit of immediate consultation and group analysis. However, telemedicine can connect consultants, surgeons, patients, and databases. The Yale Telemedicine Center has developed network schemes, which connect the OR of trainees with the laboratory of the teacher, and has opened a continuum between pedagogy and product. The program has connected regional hospitals, connected components of hospital systems, and has been used in international testbeds. The particular operative procedures studied have been laparoscopic procedures. The consultant is based at Yale and is connected with the distant OR to share the laparoscopic surgical field. Connection includes real time video, audio and the ability to draw instruction on the OR screen. Bandwidths as low as 12kbs(POTS) have been employed with modification with effective intervention. The potential for quality improvement is substantial, and inclusion in quality programs is strongly recommended.

TRAM flap perforator ligation and the delay phenomenon: development of an endoscopic/laparoscopic delay procedure.

Despite its versatility in breast reconstruction, the TRAM flap is at times subject to ischemic compromise, especially in certain high risk populations. A preoperative delay procedure can decrease the likelihood of TRAM flap failure or fat necrosis, but the required extent of this delay procedure is not clearly defined. In an attempt to augment flap vascularity while reducing surgical dissection and morbidity, six distinct delay procedures and a nondelayed control were compared in a rat TRAM flap model (n = 8 for all groups). An important feature that was incorporated into several groups was the ligation of the contralateral rectus perforators through minimal skin incisions (endoscopic analogy, groups 4 to 7). The most effective delay procedure was the combination of contralateral rectus perforator ligation and ipsilateral dominant pedicle ligation (group 7), which was achieved with two minimal skin incisions and no significant flap undermining. This procedure reduced the flap necrosis from 63.2 +/- 5.8 percent (control) to 13.5 +/- 3.3 percent (p < 0.001). After completion of the animal studies, clinical application of a "minimally invasive" TRAM flap delay procedure was then undertaken in eight high risk patients with only modest ischemic compromise. Although the clinical experience is too early to draw definite conclusions, we feel that "endoscopic delay" has potential as a modality that will increase flap vascularity but minimize the morbidity of the preliminary procedure.
