Robotic assisted rectopexy.

BACKGROUND: During the last 3 years, robotic surgery has had a considerable impact on minimally invasive surgery in a wide range of specialties. This study describes the surgical technique and preliminary results of our first 6 cases of robotic assisted suture rectopexy. METHODS: During a period of 13 months 6 patients with full thickness rectal prolapse were operated on with the da Vinci surgical system. All patients were considered suitable for a suture rectopexy. Setting-up time, procedure time, patient recovery, and hospital stay were recorded and compared with the current literature. RESULTS: All operations were completed successfully using the robotic system. There were no major complications and no deaths. Mean setting-up time was 28 minutes, mean operation time was 127 minutes, and mean hospital stay was 6 days. At 3 to 6 months of follow-up all patients are in good health, with no signs of recurrence and no reports of constipation. CONCLUSIONS: Robotic assisted suture rectopexy is feasible and safe and apparently meets accepted standards of laparoscopic surgery.

The impact of minimally invasive surgical techniques.

The use of minimally invasive techniques (MIT) in patient care is well documented in ancient history; however, it was not until the 1990s that advancements in technology enabled surgeons to realize the true potential of this approach. The minimally invasive approach has revolutionized surgical care, significantly reducing postoperative pain, recovery time, and hospital stays with marked improvements in cosmetic outcome and overall cost-effectiveness. It is now used around the world and in all major fields of surgery, compelling changes in training programs in order to assure quality control and patient safety. The bond between surgeons practicing minimally invasive surgery (MIS) and the high-tech industry is of utmost importance to future developments. Surgical robotic systems represent the most technologically advanced product of this collaboration, and their potential application in MIS shows much promise. As technology advances, additional developments in MIT are likely.

Focused, minimally invasive radio-guided parathyroidectomy: a feasible and safe option for elderly patients with primary hyperparathyroidism.

BACKGROUND: Primary hyperparathyroidism in elderly patients is usually associated with additional co-morbidity that increases operative risk, and thus many geriatric patients are denied the benefit of surgery for a single parathyroid adenoma. OBJECTIVES: To evaluate the safety and efficacy of accurate single photon emission computed tomography sestamibi scintigraphy, enabling precise localization of a single adenoma, in the geriatric population. METHODS: Twenty-two patients aged 70 years and over with biochemically proven PHPT and with a single parathyroid adenoma identified by localization studies (sestamibi SPECT scan and ultrasonography) underwent 23 operations over 29 months (out of a total of 140 patients operated upon during the same period). Immediate preoperative sestamibi scintigraphy and marking of focal adenoma uptake followed by intraoperative hand-held gamma probe were used for the removal of the parathyroid adenoma by unilateral minimal access surgery. Associated major co-morbid conditions and pre- and postoperative calcium, phosphorus and parathormone levels were recorded. Indications for surgery were listed and operative and postoperative complications were noted. The patients were followed for a mean period of 17.7 months using the same parameters. RESULTS: The 22 patients with PHPT had a mean age of 76.3 +/- 5.9 years (range 70-88 years) and a female to male ratio of 13:9. Associated co-morbidity included ischemic heart disease (n = 15), hypertension (n = 22), non-insulin-dependent diabetes mellitus (n = 9), chronic obstructive pulmonary disease (n = 3), and previous neck surgery (n = 3). Mean preoperative serum calcium, phosphorous and PTH were 11.7 +/- 1.3 mg/dl, 2.5 +/- 0.5 mg/dl and 160.9 +/- 75.4 pg/ml respectively. In 20 of the 22 patients, surgery was successful in curing PHPT (91%). One patient had persistent hypercalcemia due to a missed adenoma, and repeat operation (by focused minimal accesss surgery) was successfully performed 2 weeks later. There were no complications and no morbidity postoperatively. Mean postoperative serum calcium, phosphorous and PTH were 9.6 +/- 1.2 mg/dl, 3.0 +/- 0.5 mg/dl and 35.2 +/- 24 pg/ml respectively. In all patients, serum calcium levels remained normal (9.7 +/- 1.3 mg/ml) after long-term follow-up (mean 17.7 +/- 9.6 months). CONCLUSIONS: Minimally invasive, radio-guided focused parathyroidectomy for a single adenoma is a safe and effective method to cure hyperparathyroidism in the elderly. Success of surgery is directly related to the surgeon's experience and to the precise localization marking provided by sestamibi scintigraphic SPECT localization and concurrent sonographic findings.
