         BACKGROUND: Robotic total mesorectal excision (RTME), a novel approach for the treatment
of rectal cancer, has been shown in previous studies to be safe and effective. However, the results of
this approach compared with laparoscopic total mesorectal excision (LTME) have not been reported in
terms of clinical outcome and oncologic data. This study compared early outcomes for rectal cancer
between two groups. METHODS: Between April 2003 and March 2009, 82 patients from a
prospectively maintained database were enrolled in a case-matched study. The patients were matched
for gender, age, body mass index (BMI), and type of operative procedure. RESULTS: Neoadjuvant
chemoradiotherapy was performed for 33 RTME patients (80.5%) and 18 LTME patients (43.9%) (p =
0.001). The mean operative time was 296 min for RTME and 315 min for LTME (p = 0.357). The
number of conversions were 3 (7.3%) for RTME and 9 (22%) for LTME (p = 0.12). The anastomotic
leak rate after surgery did not differ between RTME (n = 3, 8.6%) and LTME (n = 1, 2.9%) (p =
0.62). The mean number of harvested lymph nodes was 13.1 with RTME and 16.2 with LTME (p =
0.07), and negative distal resection margins (DRMs) were noted in all surgical specimens. Positive
circumferential resections (CRMs) were identified in 2.4% of the RTME cases and 4.9% of the LTME
cases. No difference was noted in lengths of the DRMs, times until a liquid diet, or postoperative
hospital stays. The total hospitalization costs were higher in the RTME group, although the difference
did not reach statistical significance. There was no operative mortality or port-site recurrence in either
group. CONCLUSION: For rectal cancer, RTME may be as feasible and safe as LTME in terms of
technical and oncologic issues. Further prospective randomized trials are necessary for conclusions to
be drawn concerning definite oncologic outcomes of robotic procedures for rectal cancer.

"Minimally invasive sequential treatment of synchronous colorectal liver metastases by
laparoscopic colectomy and robotic right hepatectomy."
Giulianotti, P. C., A. Giacomoni, et al. (2010).
International Journal of Colorectal Disease.

          PURPOSE: The ideal timing for patients with colorectal cancer to undergo surgery for
resectable synchronous liver metastases remains under debate. We describe a new sequential
approach using laparoscopic/robotic surgery for the treatment of synchronous liver metastases.
METHODS: A 73-year-old man presented with sigmoid cancer and a single 8-cm right liver metastasis.
A staged sequential minimally invasive approach was planned. A laparoscopic left colectomy was
performed first, followed by a robotic right hepatectomy 10 days later. RESULTS: The left colectomy
lasted 120 min with a negligible blood loss (<10 mL). The right hepatectomy was completed
robotically with an operating time of 330 min and intraoperative blood loss of 300 mL. The
postoperative course was uneventful and the patient was discharged at postoperative day 8 of the
liver resection. Three weeks later, the patient received adjuvant chemotherapy. At 26-months follow
up, the patient was alive without recurrence. CONCLUSIONS: This report suggests the technical
feasibility and safety of a sequential totally minimally invasive approach for synchronous colorectal
liver metastases. In selected patients, this approach can avoid the risk of a synchronous associate
major liver/colonic resection using the advantages of minimally invasive surgery.

"Efficacy of the da vinci surgical system in abdominal surgery compared with that of
laparoscopy: a systematic review and meta-analysis."
Maeso, S., M. Reza, et al. (2010).
Annals of Surgery 252(2): 254-262.

         AIM:: The main aim of this review was to compare the safety and efficacy of the Da Vinci
Surgical System (DVSS) and conventional laparoscopic surgery (CLS) in different types of abdominal
intervention. SUMMARY OF BACKGROUND DATA:: DVSS is an emerging laparoscopic technology. The
surgeon directs the robotic arms of the system through a console by means of hand controls and
pedals, making use of a stereoscopic viewing system. DVSS is currently being used in general,
urological, gynecologic, and cardiothoracic surgery. METHODS:: This systematic review analyses the
best scientific evidence available regarding the safety and efficacy of DVSS in abdominal surgery. The
results found were subjected to meta-analysis whenever possible. RESULTS:: Thirty-one studies, 6 of
them randomized control trials, involving 2166 patients that compared DVSS and CLS were examined.
The procedures undertaken were fundoplication (9 studies, one also examining cholecystectomy),
Heller myotomy (3 studies), gastric bypass (4), gastrectomy (2), bariatric surgery (1),
cholecystectomy (4), splenectomy (1), colorectal resection (7), and rectopexy (1). DVSS was found to
be associated with fewer Heller myotomy-related perforations, a more rapid intestinal recovery time
after gastrectomy-and therefore a shorter hospital stay, a shorter hospital stay following
cholecystectomy (although the duration of surgery was longer), longer colorectal resection surgery
times, and a larger number of conversions to open surgery during gastric bypass. CONCLUSIONS::
The publications reviewed revealed DVSS to offer certain advantages with respect to Heller myotomy,
gastrectomy, and cholecystectomy. However, these results should be interpreted with caution until
randomized clinical trials are performed and, with respect to oncologic indications, studies include
variables such as survival.



"Robotic assisted laparoscopic colectomy."

        Robotic surgery has evolved over the last decade to compensate for limitations in human
dexterity. It avoids the need for a trained assistant while decreasing error rates such as perforations.
The nature of the robotic assistance varies from voice activated camera control to more elaborate
telerobotic systems such as the Zeus and the Da Vinci where the surgeon controls the robotic arms
using a console. Herein, we report the first series of robotic assisted colectomies in Ireland using a
voice activated camera control system.

laparoscopic Roux-en-Y gastric bypass."
Scozzari, G., F. Rebecchi, et al. (2010).
Surgical Endoscopy.

         BACKGROUND: Traditional laparoscopic surgery presents some difficulties for morbidly obese
patients due to limited motion of instruments related to a thick abdominal wall, intraabdominal fat,
and a large hepatic left lobe, with consequent loss of dexterity and greater musculoskeletal
discomfort. Robotic technique could potentially overcome these limitations. This study aimed to
evaluate robot-assisted laparoscopic Roux-en-Y gastric bypass in morbidly obese patients and to
compare the results of robotic assistance with those of traditional laparoscopic technique. METHODS:
Between September 2006 and June 2009, 110 morbidly obese patients underwent laparoscopic Roux-
en-Y gastric bypass with robot-assisted hand-sewn gastrojejunal anastomosis using the da Vinci
Surgical System. The data for these patients was compared with the data for 423 consecutive patients
treated in a standard laparoscopic manner during the same period. RESULTS: The patients had a
mean preoperative age of 42.6 years, a mean weight of 127.5 kg, and a mean body mass index (BMI)
of 46.7 kg/m(2). The total mean operative time was 247.5 min. The robotic setup time was 10.1 min,
and the robotic operative time was 54.5 min. The conversion rate was nil. The intraoperative
complication rate was 4.5%. The early and late major postoperative complication rates were 3.6 and
6.4% respectively. The cost per patient was 5777.76 <euro>. For the standard laparoscopy, the
operative time was significantly shorter (187 min; p < 0.001), and the costs per patient were
significantly lower (4658.28 <euro>; p < 0.001), whereas no differences were found in terms of the
intra- or postoperative complication rates, revisional surgery, or hospital length of stay.
CONCLUSIONS: Although safe and intuitive, the robotic approach was burdened by a longer operative
time and higher equipment costs. Moreover, it did not seem to provide a real advantage over standard
laparoscopy in terms of hospital length of stay and complications rates.

"Considerations for personalized surgery in patients with papillary thyroid cancer."
Tufano, R. P. and E. Kandil (2010).
Thyroid 20(7): 771-776.

         BACKGROUND: Personalizing treatment for papillary thyroid cancer (PTC) requires a
multidisciplinary approach. The surgical management of PTC has long been based on retrospective
studies focusing on endpoints that are of debatable significance. There is considerable debate in the
literature regarding the optimal initial treatment for PTC. Many of these issues are discussed in this
review. These debates have hindered the development of a tailored treatment strategy. SUMMARY:
The ability to optimally personalize a surgical plan for the treatment of PTC is ultimately dependent on
an understanding of the biological behavior of that individual patient's tumor. We are at the genesis of
an age where molecular biology advances endeavor to profile a patient's tumor behavior. This review
summarizes current strategies for managing PTC, where we are with personalizing surgery for these
patients, and where we hope to go. Thyroid surgery is one of the newest fields for the application of
minimally invasive techniques and can now be accomplished endoscopically or with robotic assistance
in many patients who therefore may benefit from these alternative approaches. CONCLUSION: When
treating a patient with PTC, it seems prudent to weigh the many factors discussed in this review to
individualize the most optimal surgical plan.
