Abstract
Lymph node metastasis is a major metastatic route of cancer and significantly influences the prognosis of cancer patients. Radical lymphadenectomy is crucial for a successful surgery. However, iatrogenic normal organ injury during lymphadenectomy is a troublesome complication. Here, this paper reports a kind of organic nanoprobes (IDSe-IC2F nanoparticles (NPs)) with excellent second near-infrared (NIR-II) fluorescence and photothermal properties. IDSe-IC2F NPs can effectively label lymph nodes and helped achieve high-contrast lymphatic imaging. More importantly, by jointly using IDSe-IC2F nanoparticles and other kinds of nanoparticles with different excitation/emission properties, a multichannel NIR-II fluorescence imaging modality and imaging-guided lymphadenectomy is proposed. With the help of this navigation system, the iatrogenic injury can be largely avoided. In addition, NIR-II fluorescence imaging-guided photothermal treatment ("hot" strategy) can ablate those metastatic lymph nodes which are difficult to deal with during resection ("cold" strategy). Nanoprobes-assisted and multichannel NIR-II fluorescence imaging-guided "cold" and "hot" treatment strategy provides a general new basis for the future precision surgery.

Abstract
We developed an en bloc lymphadenectomy method in the upper mediastinum with a single-port mediastinoscopic cervical approach. This study was designed to evaluate the safety and efficacy of single-port mediastinoscope-assisted transhiatal esophagectomy for thoracic esophageal cancer. The perioperative outcomes of 60 patients with thoracic esophageal cancer who underwent this operation between March 2014 and June 2016 were retrospectively analyzed. The upper mediastinal dissection including lymphadenectomy along the left recurrent laryngeal nerve, using a left cervical approach, was performed with a single-port mediastinoscopic technique, which was used to improve the visibility and handling in the deep mediastinum around the aortic arch. The lymphadenectomy along the right recurrent laryngeal nerve was performed under direct vision using a right cervical approach. Bilateral cervical approaches were followed by hand-assisted laparoscopic transhiatal esophagectomy with en bloc lymphadenectomy in the middle and lower mediastinum. Tumors were mainly located in the middle thoracic esophagus (n = 33), and most tumors were squamous cell carcinoma (n = 58). Pretreatment diagnoses were stage I, 19; II, 13; III, 24; IV, 4. Preoperative chemotherapy was performed for 40 patients. The median operation time and blood loss were 363 minutes and 235 mL, respectively. There were two patients who underwent conversion to thoracotomy. Perioperative complications were evaluated and graded according to the Clavien-Dindo (CD) and the Esophagectomy Complications Consensus Group (ECCG) classifications. Postoperatively, pneumonia was observed in four patients (CD, Grade II, 2; Grade IIIb, 2), although vocal cord palsy was more frequent (ECCG, Type I, 12; Type III, 8). The median number of thoracic lymph nodes resected was 21, and the R0 resection rate was 95%. Single-port mediastinoscope-assisted transhiatal esophagectomy is feasible, in terms of perioperative outcomes, for a radical surgery for thoracic esophageal cancer, although its safety needs to be further demonstrated.

Abstract
RATIONALE Understanding the status of internal mammary lymph nodes of breast cancer is critical in the accurate staging of breast cancer and the development of accurate therapeutic regimen for selected patients. Current techniques for dissection of internal mammary lymph node biopsy involve endoscopic or Traditional thoracic surgery, An important drawback of the current techniques is the great trauma caused by them. PATIENT CONCERNS Da Vinci robotic surgery system (Intuitive Surgical Inc. Sunnyvale, CA) was used to perform the internal mammary lymph chain excision for a breast cancer patient with left internal mammary lymph node metastasis. DIAGNOSES Positron emission tomography-computed tomography examination and Ultrasonography examination. INTERVENTIONS In this paper, we introduce a Robot-assisted technique for dissection of internal mammary lymph node biopsy with only 3 small trocar ports. This technique reduces the incision size and considerably reduce the trauma. OUTCOMES The operation lasted a duration of 1.5 hours. The operation was carried out smoothly with removal of 9 internal mammary lymph nodes in total. The amount of intra operative bleeding was less than 10 ml. The patient's postoperative recovery was fast. 11-month postoperative follow-up showed that the patient recovered well after surgery, no local recurrence or distant metastasis was found, and no obvious discomfort was reported. LESSONS Robot-assisted excision of internal mammary lymph chain in breast cancer is a safe, effective and simple operation with minimal invasion.

Abstract
BACKGROUND The seroma is one of the most common complications in the axillary lymph nodal dissection (different surgical approaches have been tried to reduce the seroma incidence). In our study we evaluate the outcome of patients using or not the ultrasonic scalpel (Harmonic scalpel) according to a standardized surgical technique. PATIENTS AND METHODS From January 2011 to December 2015 120 patients underwent axillary dissection for breast cancer. Patients were divided in two groups: patients belonging to the first group underwent Harmonic scalpel dissection and patients belonging to the second group underwent classical dissection. Each group consisted of 60 patients. Quadrantectomy (QUAD) was performed in 54 patients, 66 women underwent mastectomy. In all patients axillary dissection included the I, II and III level. We compared two groups in terms of: time of surgery, hematoma, drainage volume, days of sealing drainage, seroma formation, number of post-seroma aspirations, upper limb lymphedema, wound infections, post-operative pain. RESULTS Statistically significant results were obtained in terms of the total volume of the breast and axillary drainage in the two techniques. There were no significant differences in the two samples in terms of operative time incidence of seroma, post-operative hematoma, wound infection, and lymphedema of the upper limb. CONCLUSION The small number of cases did not allow us to reach definitive conclusions. The use of Harmonic scalpel seems to show smaller incidence of seroma and reduction of the amount of both breast and axillary drainages. Further studies are needed to define the real advantage in terms of cost benefit of using these devices in the axillary surgery.

Abstract
D2 lymphadenectomy is currently the worldwide standard operation for locally advanced gastric cancer and D2+ is an option for some selected patients. The D2 plus lymphadenectomy includes No.8p, No.10, No.11d, No.12b, No.12p, No.13, No.14v, No.16a2 and No.16b1. Dissection of these groups of lymph nodes may cause related complications. Postoperative complications that can cause prolonged inflammation have significant impact not only on mortality but also on overall survival of patients with gastric cancer even if the tumor is resected curatively. D2 plus lymphadenectomy is recommended only in high volume medical center by experienced surgeon. The adequate exposure of the operative field, right anatomical space, use of ultrasound scalpel and operator with enough patience are proved to be pivotal to prevent the complications.

Abstract
Incidence of gastric cancer is high in China and standard radical operation is currently the main treatment for gastric cancer. Postoperative complications, especially some special complications, can directly affect the prognosis of patients, even result in the increase of mortality. But the incidences of these special complications are low, so these complications are often misdiagnosed and delayed in treatment owing to insufficient recognition of medical staff. These special complications include (1) Peterson hernia: It is an abdominal hernia developed in the space between Roux loop and transverse colon mesentery after Roux-Y reconstruction of digestive tract. Peterson hernia is rare and can quickly result in gangrenous ileus. Because of low incidence and without specific clinical symptoms, this hernia does not attract enough attention in clinical practice, so the outcome will be very serious. Once the diagnosis is made, an emergent operation must be performed immediately. Peterson space should be closed routinely in order to avoid the development of hernia. (2) Lymphatic leakage: It is also called chyle leakage. Cisterna chylus is formed by gradual concentration of extensive lymphatic net to diaphragm angle within abdominal cavity. Lymphadenectomy during operation may easily damage lymphatic net and result in leakage. The use of ultrasonic scalpel can decrease the risk of lymphatic leakage in certain degree. If lymphatic leakage is found during operation, transfixion should be performed in time. Treatment includes total parenteral nutrition, maintenance of internal environment, supplement of protein, and observation by clamp as an attempt. (3)Duodenal stump leakage: It is one of serious complications affecting the recovery and leading to death after subtotal gastrectomy. Correct management of duodenal stump during operation is one of key points of the prevention of duodenal stump leakage. Routine purse embedding of duodenal stump is recommend during operation. The key treatment of this complication is to promt diagnosis and effective hemostasis.(4) Blood supply disorder of Roux-Y intestinal loop: Main preventive principle of this complication is to pay attention to the blood supply of vascular arch in intestinal edge. (5) Anastomotic obstruction by big purse of jejunal stump: When Roux-en-Y anastomosis is performed after distal radical operation for gastric cancer, anvil is placed in the remnant stomach and anastomat from distal jejunal stump is placed to make gastrojejunal anastomosis, and the stump is closed with big purse embedding. The embedding jejunal stump may enter gastric cavity leading to internal hernia and anastomotic obstruction. We suggest that application of interruptable and interlocking suture and fixation of stump on the gastric wall can avoid the development of this complication.

Abstract
Lymphocele is the most common complication after pelvic lymph node dissection (PLND). Over the years, various techniques have been introduced to prevent lymphocele, but no final conclusion can be drawn regarding the superiority of one technique over another. In this prospective study, 220 patients undergoing robot-assisted radical prostatectomy between 2012 and 2015 were randomized to receive titanium clips (group A, n=110) or bipolar coagulation (group B, n=110) to seal lymphatic vessels at the level of the femoral canal during extended PLND (ePLND). Ultrasound examination was used to detect lymphoceles at 10 and 90 d after surgery. Lymphocele was defined as any clearly definable fluid collection and was considered clinically significant when requiring treatment. There were no statistically significant differences between groups A and B regarding overall lymphocele incidence (47% vs 48%; difference -0.91%, 95% confidence interval [CI] -2.6 to 0.7; p=0.9) and the rate of clinically significant lymphocele [5% vs 4%; difference 0.75%, 95% CI, 0.1-3.2; p=0.7]. The two groups were comparable regarding mean (±SD) lymphocele volume (30±32 vs 35±39ml; p=0.6), lymphocele location (unilateral, 37% vs 35%, p=0.7; bilateral, 13% vs 14%, p=0.9), and time to lymphocele diagnosis (95% vs 98% on postoperative day 10; p=0.5). In conclusion, this trial failed to identify a difference in lymphocele occurrence between clipping and coagulation of the lymphatic vessels at the level of the femoral canal during robot-assisted ePLND for prostate cancer. PATIENT SUMMARY In this study we compared the frequency of postoperative complications after sealing lymphatic vessels from the leg to the abdomen using metallic clips or electrical coagulation during robot-assisted surgery for prostate cancer. We found no difference in postoperative complications between the two methods.

Abstract
Robotic surgery offers advantages for operating in a narrow space such as inside the pelvis. We report on the technique of robotic-assisted laparoscopic total proctocolectomy with lymphadenectomy and ileal pouch-anal anastomosis for ulcerative colitis with transverse colitic cancer, using the single cart position. A 46-year-old female patient was diagnosed with colitic cancer of the transverse colon during the surveillance of ulcerative colitis. Six port sites were used. Mobilization of the left-sided colon through to the rectum and mobilization of the transverse colon with lymphadenectomy around the middle colic artery were performed using the robotic surgical system. After rectal mobilization was conducted near the anus, the right side of the colon was mobilized and the ileum resected laparoscopically. Thereafter, a mucosectomy of the proctorectum was carried out through a trans-anal approach, and a hand-sewn J-pouch was performed. Finally, a diverting ileostomy was constructed through the right lower abdomen. The operative time was 460 minutes, including the console time of 361 minutes. The amount of blood loss was 76 g. The patient was discharged on postoperative day nine. Pathological results demonstrated that the depth of the lesion was T3, and the positive lymph node was 1 of 115 retrieved lymph nodes. There were no complications or mortality. Robotic-assisted total proctocolectomy and lymphadenectomy with ileal pouch-anal anastomosis for transverse colitic cancer of ulcerative colitis was performed safely using the single cart position.

Abstract
OBJECTIVE To systematically review previous studies and to evaluate the feasibility and safety of video endoscopic inguinal lymphadenectomy (VEIL) in vulvar cancer. METHODS We conducted a comprehensive review of studies published through September 2014 to retrieve all relevant articles. The PubMed, EMBASE, Web of Science, Cochrane Library, Wan Fang Data and Chinese National Knowledge Infrastructure databases were systematically searched for all relevant studies published in English or Chinese through September 2014. Data were abstracted independently by two reviewers, and any differences were resolved by consensus. RESULTS A total of 9 studies containing 249 VEIL procedures involving 138 patients were reviewed. Of the 249 VEIL procedures, only 1 (0.4%) was converted to an open procedure for suturing because of injury to the femoral vein. The range of operative time was 62 to 110 minutes, and the range of estimated blood loss was 5.5 to 22 ml. The range of the number of harvested lymph nodes was 7.3 to 16. The length of hospital stay varied from 7 to 13.6 days across reports. The incidence of lymph node metastasis was 19.7% (27/138), and the recurrence rate was 4.3% (3/70) within 3 to 41 months of follow-up. One or more short-term complications were documented in 18 of 138 (13.0%) patients. Complications after VEIL were observed in 14 (10.13%) patients and in 15 (6.0%) of the VEIL cases, including major lymphocyst formation in 9 (3.6%), lymphorrhea in 2 (0.8%), inguinal wound infection without wound breakdown in 3 (1.2%) and lymphedema in 1 (0.4%). CONCLUSIONS VEIL appears to be a feasible procedure in the management of vulvar cancer. There may be potential benefits that result in lower morbidity compared to traditional methods, but this has yet to be objectively proven.

Abstract
BACKGROUND Open radical cystectomy (ORC) and urinary diversion in patients with bladder cancer (BCa) are associated with significant perioperative complication risk. OBJECTIVE To compare perioperative complications between robot-assisted radical cystectomy (RARC) and ORC techniques. DESIGN, SETTING, AND PARTICIPANTS A prospective randomized controlled trial was conducted during 2010 and 2013 in BCa patients scheduled for definitive treatment by radical cystectomy (RC), pelvic lymph node dissection (PLND), and urinary diversion. Patients were randomized to ORC/PLND or RARC/PLND, both with open urinary diversion. Patients were followed for 90 d postoperatively. INTERVENTION Standard ORC or RARC with PLND; all urinary diversions were performed via an open approach. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Primary outcomes were overall 90-d grade 2-5 complications defined by a modified Clavien system. Secondary outcomes included comparison of high-grade complications, estimated blood loss, operative time, pathologic outcomes, 3- and 6-mo patient-reported quality-of-life (QOL) outcomes, and total operative room and inpatient costs. Differences in binary outcomes were assessed with the chi-square test, with differences in continuous outcomes assessed by analysis of covariance with randomization group as covariate and, for QOL end points, baseline score. RESULTS AND LIMITATIONS The trial enrolled 124 patients, of whom 118 were randomized and underwent RC/PLND. Sixty were randomized to RARC and 58 to ORC. At 90 d, grade 2-5 complications were observed in 62% and 66% of RARC and ORC patients, respectively (95% confidence interval for difference, -21% to -13%; p=0.7). The similar rates of grade 2-5 complications at our mandated interim analysis met futility criteria; thus, early closure of the trial occurred. The RARC group had lower mean intraoperative blood loss (p=0.027) but significantly longer operative time than the ORC group (p<0.001). Pathologic variables including positive surgical margins and lymph node yields were similar. Mean hospital stay was 8 d in both arms (standard deviation, 3 and 5 d, respectively; p=0.5). Three- and 6-mo QOL outcomes were similar between arms. Cost analysis demonstrated an advantage to ORC compared with RARC. A limitation is the setting at a single high-volume, referral center; our findings may not be generalizable to all settings. CONCLUSIONS This trial failed to identify a large advantage for robot-assisted techniques over standard open surgery for patients undergoing RC/PLND and urinary diversion. Similar 90-d complication rates, hospital stay, pathologic outcomes, and 3- and 6-mo QOL outcomes were observed regardless of surgical technique. PATIENT SUMMARY Of 118 patients with bladder cancer who underwent radical cystectomy, pelvic lymph node dissection, and urinary diversion, half were randomized to open surgery and half to robot-assisted laparoscopic surgery. We compared the rate of complications within 90 d after surgery for the open group versus the robotic group and found no significant difference between the two groups.

Abstract
BACKGROUND Persistent differentiated papillary thyroid cancer (PTC) with metastasis followed by radical locoregional surgery is an indication for limited reoperation. Despite excellent prognosis the major challenge is controlling locoregional recurrences. AIM To evaluate the efficacy of radioguided excision with combined use of gamma probe and an hand-held gamma camera. PATIENTS AND METHODS From June 2009 to January 2012, we enrolled twenty-two patients with locoregional PTC recurrences, previously undergone to central and/or lateral neck dissection for PTC. The diagnosis of recurrent PTC was based on thyroglobulin (TG) evaluation [basal and after thyroid stimulating hormone (TSH) stimulation], ultrasound (US), iodine-131 (131I) whole body scan (WBS) and fine needle aspiration cytology (FNAC). In the morning of surgery, radiotracer was injected directly into the lesions by US guide. Careful dissection was carried out using gamma probe and hand held gamma camera. Metastatic lymph nodes were identified and excised. RESULTS In all the patients recruited, 39 pathologic nodes were injected and 61 nodes were removed. Among the removed nodes, 22 (36.1%) were additional nodes (not injected by radiotracer). Of the additional lymph nodes, 7 (31.8%) were metastatic. Mean radioactive count of the lesion (28.633±9.218 counts/s) was higher than tumor bed (385.73±192.23 counts/s) (p < 0.0001). No complications were observed during radioguided excision, neither on post-operative period. CONCLUSIONS The use of hand-held gamma camera in addition to gamma probe in our preliminary study allows a minimally invasive procedure and safer identifications of the lesions and ensures the completeness of the excision in a difficult surgical field.

Abstract
More than 350,000 new cases of bladder cancer are diagnosed worldwide each year; the vast majority (> 90%) of these are transitional cell carcinomas (TCC). The most important risk factors for the development of bladder cancer are smoking and occupational exposure to toxic chemicals. Painless visible haematuria is the most common presenting symptom of bladder cancer; significant haematuria requires referral to a specialist urology service. Cystoscopy and urine cytology are currently the recommended tools for diagnosis of bladder cancer. Excluding muscle invasion is an important diagnostic step, as outcomes for patients with muscle invasive TCC are less favourable. For non-muscle invasive bladder cancer, transurethral resection followed by intravesical chemotherapy (typically Mitomycin C or epirubicin) or immunotherapy [bacillus Calmette-Guérin (BCG)] is the current standard of care. For patients failing BCG therapy, cystectomy is recommended; for patients unsuitable for surgery, the choice of treatment options is currently limited. However, novel interventions, such as chemohyperthermia and electromotive drug administration, enhance the effects of conventional chemotherapeutic agents and are being evaluated in Phase III trials. Radical cystectomy (with pelvic lymphadenectomy and urinary diversion) or radical radiotherapy are the current established treatments for muscle invasive TCC. Neoadjuvant chemotherapy is recommended before definitive treatment of muscle invasive TCC; cisplatin-containing combination chemotherapy is the recommended regimen. Palliative chemotherapy is the first-choice treatment in metastatic TCC.

Abstract
Introduction of robotic surgery in the first decade of the 21 century was one of the biggest breakthroughs in surgery since the introduction of anesthesia. For the first time in history the surgeon was placed remotely from the patient and was able to operate with the device that has more degrees of freedom than human hand. Initially developed for the US Military in order to allow surgeons to be removed from the battlefield, surgical robots quickly made a leap to the mainstream medicine. One of the first surgical uses for the robot was cardiac surgery but it is urology and prostate surgery that gave it a widespread popularity Gynecologic surgeons caught on very quickly and it is estimated that 31% of hysterectomies done in the United States in 2012 will be done robotically. With over half a million hysterectomies done each year in the US alone, gynecologic surgery is one of the main driving forces behind the growth of robotic surgery Other applications in gynecology include myomectomy oophorectomy and ovarian cystectomy resection of endometriosis and lymphadenectomy Advantages of the surgical robot are clearly seen in myomectomy The wrist motion allows for better more precise suturing than conventional "straight stick" laparoscopy The strength of the arms allow for better pulling of the suture and the third arm for holding the suture on tension. Other advantage of the robot is scaling of the movements when big movement on the outside translates to very fine movement on the inside. This enables much more precise surgery and may be important in the procedures like tubal anastomosis and implantation of the ureter Three-dimensional vision provides excellent depth of field perception. It is important for surgeons who are switching from open surgeries and preliminary evidence shows that it may allow for better identification of lesions like endometriosis. Another big advantage of robotics is that the surgeon sits comfortably with his/her arms and head supported. This results in much less fatigue and therefore increases precision and potentially may decrease the number of medical errors. The eyes of the surgeon are directed at where the hands should be, which is more natural, allows for a more natural body position and mimics open surgery Robot also enables better teaching, especially when two consoles are used. The surgeon and the student may be either sharing the instruments with two consoles or switching between one another. In a situation where the student operates, the surgeon can use the telestation to teach. Robotic simulator attached to one of the consoles allows students to practice after hours. In summary surgical robot is a great tool, especially in gynecology but also in urology cardiac surgery general surgery and laryngology The device will evolve and most likely with time will eliminate laparoscopy

Abstract
BACKGROUND The ultrasonically activated scalpel has been introduced as an alternative to conventional methods of hemostasis in surgical procedures. The present study investigated the benefits of using the Harmonic FOCUS (HF) scalpel in breast-conserving surgery (BCS) and in axillary staging surgery. METHODS All early-stage breast cancer patients who underwent BCS and axillary staging surgery between January 2009 and December 2010 were retrospectively identified. Those patients treated with the HF scalpel were defined as the HF group, while patients whose surgery involved the electrocautery and the clamp-and-tie technique were designated as the conventional method (CM) group. Both groups were subsequently divided into the axillary lymph node dissection (ALND) and sentinel lymph node biopsy (SLNB) subgroups, respectively. RESULTS A total of 89 patients were included in the study, with 41 patients in the HF group and 48 in the CM group. There were 13 patients in the SLNB subgroup and 28 were in the ALND subgroup of the HF group, and 21 patients were in the SLNB subgroup and 27 in the ALND subgroup of the CM group. Multiple linear regression analysis revealed that the length of surgery was significantly reduced in the ALND subgroup of the HF group (β = -16.70, p < 0.001). The incidence of axillary numbness was significantly decreased in the ALND subgroup of the HF group, with the results measured by multiple logistic regression analysis (OR = 0.27, p = 0.044). No statistically significant differences were identified concerning intraoperative blood loss, postoperative drainage, and seroma between the HF and CM groups. CONCLUSION Using the Harmonic FOCUS scalpel in breast conserving surgery and axillary lymph mode dissection significantly reduced the length of surgery and decreased the axillary numbness rate as compared to conventional methods.

Abstract
Inguinal lymphadenectomy plays a critical role in the diagnosis and treatment of several neoplastic diseases. Frequently, bilateral lymphadenectomy is undertaken for staging and/or treatment of genitourinary cancers. Our objective was to determine if bilateral endoscopic lymphadenectomy could be performed simultaneously, in an effort to decrease overall anesthetic and operative time. This was accomplished by utilizing two carbon dioxide insufflators concurrently. This approach requires careful positioning of the patient, surgical team, and instrumentation, as well as special anesthetic considerations necessary to avoid severe hypercarbia. Simultaneous bilateral endoscopic inguinal lymphadenectomy is a technically feasible and efficient surgical approach.

Abstract
BACKGROUND Robotic surgery for the treatment of gastric cancer has been reported, but the technique is not yet established. The objective of this study was to assess the feasibility and safety of our novel integrated procedure for robotic suprapancreatic D2 nodal dissection during distal gastrectomy. METHODS At our hospital from January 2009 to December 2010, a total of 25 consecutive cases of gastric cancer were treated by robotic distal gastrectomy with intracorporeal Billroth I reconstruction. These patients were enrolled in a prospective study to assess the safety and feasibility of robotic distal gastrectomy with nodal dissection by our novel integrated approach, which consists of three elements: arm formation, the surgical approach, a cutting device. To evaluate the learning curves involved in this approach, clinicopathologic features and surgical outcomes were compared between the initial (n = 12) and late (n = 13) phases. RESULTS All operations were completed without the need for open or conventional laparoscopic surgery. The mean operating time was 361 ± 58.1 min (range 258-419 min), and blood loss recorded was 51.8 ± 38.2 ml (range 4-123 ml). The median number of retrieved lymph nodes was 44.3 ± 18.4 (range 26-95). R0 resection was accomplished in all cases. There were no deaths or complications related to pancreatic damage. Operating time and surgeon console time for the late phase were significantly shorter than those for the initial phase. CONCLUSIONS Our novel robotic approach for D2 nodal dissection in gastric cancer is feasible and safe.

Abstract
OBJECTIVE To evaluate the technical feasibility, effectiveness, and safety of robot-assisted gastrectomy(RAG) with lymphadenectomy using the Da Vinci system. METHODS A total of 9 patients in our institute from March 17 to April 24 2010 underwent RAG. Clinicopathologic characteristics and surgical outcomes were summarized. RESULTS All operations were performed successfully without conversion to either open or laparoscopic approach. There were 5 total gastrectomies,2 distal gastrectomies, 1 proximal gastrectomy and 1 wedge gastrectomy with D(1) or D(2) lymphadenectomy. The total operative time was 150 to 440 minutes. Total blood loss ranged from 10 to 100 ml. The ranges of harvested lymph nodes were 19-24 for D(1) patients and 28-38 for D(2) patients. There was 1 case of postoperative gastric leakage, which were managed conservatively. CONCLUSIONS RAG with lymphadenectomy can be applied safely and effectively for patients with gastric cancer.

Abstract
The ultrasound scissors are recently emerging as an alternative surgical tool for dissection and haemostasis and have been extensively used in the field of minimally invasive surgery. We studied the utility and advantages of this instrument compared with electrocautery to perform axillary dissection. The operative and morbidity details of thirty-five breast cancer patients who underwent axillary dissection using the ultrasound scissors were compared with 35 matched controls operated with electrocautery by the same surgical team. There was no significant difference in the operating time between the ultrasound scissors and electrocautery group (36 and 30 mins, p>0.05). The blood loss (60 +/- 35 ml and 294 +/- 155 ml, p<0.001) and drainage volume (200 +/- 130 ml and 450 +/- 230 ml, p<0.001) were significantly lower in the ultrasound scissors group. There was a significant reduction of draining days in ultrasound scissors group (mean one and four days, respectively p<0.05). There was significant difference in the seroma rate between the two groups (10% and 30%, respectively). Axillary dissection using harmonic scalpel is feasible and the learning curve is short. Ultrasound scissor significantly reduces the blood loss and duration of drainage as compared to electrocautery.

Abstract
A lobectomy is a standard surgical operation for lung cancer. Recently, the general surgical approach for this operation has been the use of a video-assisted procedure (video-assisted thoracic surgery: VATS). Almost all thoracoscopic instruments have been developed from classical instruments, scissors or forceps. We think that thoracoscopic instruments are often limited about the handling for the procedures, because the procedures are widely demanded to understand anatomical variations in an intrathoracic space. Fusion instruments (NT forceps) with atraumatic dispositions have been developed on our device, and they are so useful tools in all technical handlings for standard operations, lobectomy. And the forceps with a new device (such as LigaSure and Harmonic Scalpel) especially show a good combination technique.

Abstract
STUDY OBJECTIVE To describe the feasibility and outcome of total laparoscopic radical hysterectomy with or without pelvic lymphadenectomy for patients with stage I cervical cancer or severe pelvic endometriosis using harmonic shears as the sole instrument for dissection, division, and maintenance of hemostasis of all major surgical pedicles. DESIGN Retrospective review (Canadian Task Force classification II-2). SETTING University hospital and affiliate institutions. PATIENTS Seven patients who underwent total laparoscopic radical hysterectomy using harmonic shears for International Federation of Gynecology and Obstetrics stage IA2 to IB1 cervical cancer and pelvic endometriosis at our institution or affiliate hospital from January 2004 through February 2005. INTERVENTION A retrospective review of patients that underwent total laparoscopic radical hysterectomy with or without pelvic lymphadenectomy at our institution using harmonic shears was performed. Information regarding preoperative, intraoperative, and postoperative events was recorded and analyzed. MEASUREMENTS AND MAIN RESULTS Pelvic lymphadenectomy was performed in all cancer cases. Mean patient age was 40 years (range 30-53 years). Mean estimated blood loss was 143 mL (range 100-200 mL). Mean operating time was 293 minutes (range 255-385 minutes). Mean pelvic node count was 27.8 (range 24-34) for cancer cases. Mean hospital stay was 3.2 days (range 2-7 days). One patient developed a vaginal cuff abscess postoperatively that was managed conservatively with drainage in the office setting followed by intravenous antibiotics. Another patient developed urinary retention for 2 weeks after surgery. There were no other intraoperative or postoperative complications. CONCLUSION Total laparoscopic radical hysterectomy with pelvic lymphadenectomy using harmonic shears is a technically feasible and safe procedure. Larger studies and long-term follow-up are required to determine the oncologic outcomes of these patients.

Abstract
In mediastinal dissection through a right thoracotomy, the definition of station 2 is arbitrary because no anatomical landmark indicates the line drawn tangentially to the upper margin of the aortic arch. We have developed a technique to localize it by evaluating the distance between the upper aortic arch and the azygos vein on a CT scan. This distance located intraoperatively above the azygos vein permits the surgeon to draw an imaginary line parallel to the azygos vein, which we consider to be the limit between station 2 and station 4. To verify the precision of the technique, an 8-mm clip was positioned at the intersection between the imaginary line dividing station 2 and station 4 and the superior vena cava in 38 consecutive right-sided lateral muscle-sparing thoracotomies. The definition of the station 2/4 limit was defined as "excellent" if the upper aortic arch line crossed the clips, "good" if clips were </= 5mm from it, "acceptable" if the distance was 6-10 mm, and "poor" if the distance was higher than 10 mm. Clip evaluation was possible in 37 patients. The definition of the limit between station 2 and station 4 was excellent in 26 cases (70.2%), good in 10 cases (27%), acceptable in no case and poor in 1 case (2.7%). In this latter case,the presence of a lusory artery was probably responsible for the poor clip positioning. This simple technique improves the precision of lymph node staging during mediastinal dissection,providing an excellent or good definition in more than 95% of patients submitted to lateral thoracotomy. Further studies are needed to verify whether the technique is applicable with the same precision during postero and antero-lateral thoracotomy.

Abstract
BACKGROUND Despite its reduced aggressiveness and excellent results obtained in certain diseases, minimally invasive surgery did not manage to significantly lower the risks of esophageal resections. Further advances in technology led to the creation of robotic systems with their unique maneuverability of the instruments and exceptional view on the operative field, thus setting the prerequisites for performance in complex surgical procedures and offering new possibilities to a disease notorious for its dismal prognosis. MATERIALS AND METHODS The robotic-assisted transhiatal esophagectomy technique was used in a patient with squamous cell carcinoma of the lower esophagus that had high medical risk for surgical therapy. RESULTS Esophageal resection and reconstruction were possible through a robotic-assisted minimally invasive transhiatal approach. There were no intraoperative incidents, blood loss was minimal, and lymph node dissection and removal was possible during the procedure. Early ambulation and conservative treatment of the mild complications that occurred offered a favorable postoperative outcome. CONCLUSION The robotic-assisted transhiatal esophagectomy technique is feasible and safe. Complex procedures become less technically demanding with the help of the robotic system and, thus, the minimally invasive approach can be offered for the benefit of selected patients. Further studies are required to confirm these observations and to establish the role of this procedure in the future.

Abstract
Minimally invasive laparoscopic techniques have been applied to the staging and treatment of testicular cancer during the performance of retroperitoneal lymph node dissection. The da Vinci Surgical System potentially improves the safety and accuracy of this approach. We present what we believe to be the first published description of robotic-assisted retroperitoneal lymph node dissection, which was performed in an 18-year-old man with a mixed germ cell tumor. This case demonstrates the technical feasibility, safety, and accuracy of robotic-assisted retroperitoneal lymph node dissection and expands the role of minimally invasive techniques in urologic oncology.

Abstract
This is an initial report of a new method of axillary dissection via a periareolar incision and an 8 mm incision in the axilla with the da Vinci Surgical System. The 10x magnification and three-dimensional image, together with the versatility and precision of the robotic telemanipulators, has enabled us to perform nerve-sparing axillary dissection in four patients with invasive ductal carcinoma of the breast undergoing segmental (conservative) excision and level II axillary dissection. The time for the robotic axillary dissection ranged from 30 to 105 minutes (average 70.5 minutes). The average number of lymph nodes retrieved was 13 (11, 11, 13, and 17, respectively). Postoperatively all four patients recovered well and were discharged the next day. The robotic system can enhance the surgeon's ability by providing a high-definition, magnified, three-dimensional view of the operative field, intuitively controlled articulating instruments, and elimination of tremors; and it has potential benefits for the patient.

Abstract
BACKGROUND AND PURPOSE The acceptance of open retroperitoneal lymph node dissection (RPLND) for stage I and II nonseminomatous testicular cancer has decreased because of the intraoperative and postoperative morbidity of the procedure. Laparoscopic RPLND is a minimally invasive and safe alternative for low-stage germ-cell tumors. It is, however, technically demanding and should therefore be performed only in experienced centers. The purpose of the present study was to evaluate the waterjet technique for laparoscopic RPLND. PATIENTS AND METHODS A series of 18 patients with clinical stage I testis cancer (group A) and 7 patients who had received chemotherapy for stage II disease (group B) underwent laparoscopic RPLND at our institution. The procedure was performed identically to the open approach using the modified template according to Weissbach and associates. The waterjet was used for removal of lymphatic tissue from the aorta and the vena cava, as well as from the sympathetic trunk. RESULTS The operation was completed in all patients without conversion to open surgery. The mean operating time was 232 +/- 48 minutes. The waterjet was able to remove lymphatic tissue easily and atraumatically. At pressures of 20 bar, the lymph-node capsule remained completely intact, thus avoiding tumor-cell spread. Antegrade ejaculation could be preserved in all patients, who, to date, show no evidence of disease. CONCLUSIONS The waterjet allows the safe and complete removal of lymphatic tissue, leaving vulnerable anatomic structures intact. It can decrease the learning curve of laparoscopic RPLND and contribute to better acceptance of this procedure.

Abstract
OBJECTIVE To evaluate the feasibility, safety and utility of the ultrasonic shears for laparoscopic pelvic and para-aortic lymph node retrieval in the treatment of gynecologic cancers. METHODS Data on laparoscopic lymphadenectomy performed for gynecologic malignancies using ultrasonic shears over a 5-year period were collected and analyzed prospectively. RESULTS Laparoscopic lymphadenectomy using ultrasonic shears was performed on 100 patients with a median age of 58 (17-87) years. The types of malignancies included cervical (n = 29), endometrial (n = 48), ovarian (n = 15), fallopian tube (n = 2), malignant mixed mesodermal tumor (n = 2), vaginal (n = 2) and synchronous ovarian and endometrial cancers (n = 2). Sites of lymphadenectomy included pelvic (n = 49), para-aortic (n = 30) or both pelvic and para-aortic (n = 21). The median nodal yield was 22 (0-87). 66/100 were complete lymphadenectomies with a median nodal yield of 28 (2-71). The median length of hospital stay was 2 (1-13) days and the average blood loss was 148 (0-500) ml. Overall complication rate was 13%. There were 3 intra-operative complications, which were all managed laparoscopically. There were no unplanned conversions to laparotomy. There were 10 post-operative complications including port-site metastasis in a patient with positive nodes (n = 1), trocar-site hernia requiring a second laparoscopy (n = 1), deep leg vein thrombosis (n = 1), and a small bowel obstruction (n = 1). CONCLUSIONS This is the largest series to date demonstrating the safety and efficacy of ultrasonic shears in laparoscopic lymphadenectomy for gynecologic malignancies. In addition to the potential for lowering the risk for tissue damage, ultrasonic shears offer multifunctionality which allows for a simpler technique with the use of fewer instruments.

Abstract
Massive presacral bleeding arising during gynaecological surgery can be sudden, rapid and life-threatening. Further, its control and management can be challenging, since standard measures are frequently ineffective. The use of thumbtacks to control severe presacral venous haemorrhage was first reported in 1985. Despite this, it does not appear to be widely known or used in gynaecological surgery. A case is presented in which the technique was used, and the literature on its use is reviewed.

Abstract
Insulinomas are rare endocrine tumors that are mostly sporadic, benign, and small. Preoperative radiography diagnosis may be difficult. Intraoperative palpation and ultrasound remain the gold standard for detection and planned resection. Recent studies find intraoperative gamma-probe localization as a good technique for identifying primary neuroendocrine tumors. We report a case of a 75-year-old woman with functioning lymph node recurrence of a malignant insulinoma. Spleno-pancreatectomy was performed in order to treat the malignant insulinoma. Clinical, biochemical, and radiological examination confirmed the total excision of the primary lesion. However, clinical symptoms appeared 9 months later. Octreo-scan, abdominal CT, and biochemical study showed lymph node recurrence and four hepatic metastases. Surgery was performed after two [111In-DTPA] octreotide scans. Intraoperative gamma probe detection was planned in order to localize a small latero-aortic lymph node recurrence. Intraoperative count rates were high in para-aortic tissue. Para-aortic lymphadenectomy and metastasectomy were carried out. Ex-situ count rates and histological examination confirmed the recurrence. Six months later clinical and biochemical studies and scans remain negative for recurrence. Intraoperative [111In-DTPA] octreotide gamma probe examination may be a useful tool in the surgical approach to insulinoma recurrence.

Abstract
During the last decade laparoscopy has become the standard technique in the urologist's armamentarium due to constant technological advancements and refinements. Laparoscopic radical prostatectomy (LRPE), although technically demanding and associated with a considerable learning curve, has become the operative procedure of choice for patients with clinically localized prostate cancer in selected and specialized urologic centers around the globe. However, a major drawback of LRPE is the transperitoneal route of access to the extraperitoneal organ of the prostate. The principal disadvantages of LRPE are potential intraperitoneal complications. Endoscopic extraperitoneal radical prostatectomy (EERPE) is a further advancement of minimally invasive surgery as it overcomes the limitations of LRPE by the strictly extraperitoneal route of access. Based on our growing experience with this procedure we introduce several technical modifications, improvements, and refinements including a nerve-sparing, potency-preserving approach (nEERPE) in an effort to further improve this minimally invasive procedure. We report our short-term follow-up results after 300 procedures. The mean operative times were 115 min without and 150 min with lymph node dissection, in total 140 min (range: 60-260 min). There was no conversion and the transfusion rate was 1.3%. There were three early reinterventions (two bleeding and one hematoma) and five late reinterventions (four symptomatic lymphoceles and one colostomy due to a rectal fistula). Pathological stage was pT2a in 54 patients (18%), pT2b in 87 patients (29%), pT3a in 115 patients (38.3%), pT3b in 40 patients (13.3%), and pT4 in 4 patients (1.3%). Positive surgical margins were found in 9.2% (13/141) of patients with pT2 tumor and 30.3% (47/155) of patients with pT3 tumor. The mean catheterization time was 6.9 days. Six and twelve months postoperatively 86.3 and 89.6% of the patients were completely continent; 9.2% of patients needed 1-2 pads per day and 4.5 and 1.2% of patients needed more than 2 pads per day, respectively. Short-term oncological and functional results of EERPE are at least as favorable as in LRPE while operative times are shorter and complication rates are low. EERPE is a technical advancement because it combines the advantages of a totally extraperitoneal access with the advantages of a minimally invasive procedure.

Abstract
We report on 431 operations in conventional visceral surgery with the general use of the ultracision technique for preparation (thyroid resections n = 356, colonic resections n = 28, local excisions of the gastric wall n = 3, gastrectomy n = 14, anterior resections of the rectum n = 19, abdominoperineal resection of the rectum [Miles' operation] n = 11). Ligatures were only used for truncal blood vessel ligation. A thorough study of the technical possibilities is a prerequisite for the use of the ultracision technique. The general use of the ultracision technique leads to a revolutionary change of the surgical technique and saves a considerable amount of suture material. In combination with the use of bipolar electrocoagulation the ultracision technique makes the operation fast and leads to a major reduction of bleeding. The biggest disadvantage of the ultracision technique in comparison to the conventional surgical technique is the high cost of the device at present. Despite of savings of suture material, swabs and blood transfusions, the costs for the ultracision scissors are still higher due to its single use.

Abstract
BACKGROUND Complete axillary clearance is recommended as part of the treatment in selected patients with invasive breast cancer. There are a number of potential technical difficulties in performing level III axillary clearance including: the deep and high position of level II and III nodes, their close proximity to the axillary vein, the difficulty in adjusting the operating light to illuminate the different levels of the axilla and the need for at least one assistant to perform the procedure. AIM OF THE STUDY To evaluate a new axillary clearance retractor, which is designed to overcome the technical difficulties in axillary clearance. PATIENTS AND METHODS The retractor was used for level III axillary clearance in 30 patients with invasive breast cancer either as part of total mastectomy (16 patients) or breast conservation surgery (14 patients). The retractor is table-based and provides simultaneous illumination to all levels of the axilla via light bundles. It has a long L-shaped component to retract the pectoral muscles and a self-retaining component to retract the skin edges. Assistants were not required in all patients. The details of the retractor and technique is described and literature reviewed. RESULTS The mean age of patients was 54 years (range 46-83) and the mean tumour size was 24.9 mm (range 11-70). The mean number of total lymph nodes removed was 19.4 nodes (range 11-50). The mean number of lymph nodes identified in level III dissection was 2.4 nodes (range 0-8). Six patients developed axillary seroma, which was treated by aspiration. CONCLUSION The axillary clearance retractor can be used with ease and without complications. It helps to overcome the technical difficulties in this operation.

Abstract
INTRODUCTION Advanced cancers of the cervix are treated by external radiotherapy within range limits which depend on the para-aortic ganglion metastases found during surgical staging. The presence of postoperative intraperitoneal adhesions increases the risk of postradical enteritis. The aim of this study is to investigate the efficacy of an anti-adhesive substance (Intergel) undergoing para-aortic lymphadenectomy by laparotomy. MATERIALS AND METHODS We conduced a prospective, randomized study on 60 pigs divided into 2 groups (with and without Intergel) undergoing para-aortic lymphadenectomy by laparotomy to compare the efficacy of an anti-adhesive substance using an adhesion scoring system based on density and surface area in question. RESULTS There was no difference between the 2 groups in terms of duration of surgery, number of ganglia removed, postoperative mortality and per and postoperative morbidity, especially the adhesion process. CONCLUSION Administration of an anti-adhesive substance such as Intergel does not reduce the adhesion process after para-aortic lymphadenectomy in animals. However, perhaps we can not interpret these results because of the too much quantity of anti-adhesive substance for the animal weight, and because of the too precocious control.

Abstract
BACKGROUND After performing more than 500 robotic radical prostatectomy and robotic radical cystoprostatectomy in men, we attempted to develop the technique of robot-assisted radical cystectomy in women. This article describes two techniques of robot-assisted radical cystectomy for women, conventional and with preservation of the uterus and vagina. To the best of our knowledge, this is the first case series of robot-assisted radical cystectomy and urinary diversion in women. STUDY DESIGN Robot-assisted radical cystectomy was undertaken in three female patients with transitional cell carcinoma of the urinary bladder. The operation was performed with the conventional anterior approach in one patient and with a new technique in two patients, which allows preservation of urethra, uterus, vagina, and both ovaries. As planned, the radical cystectomy was done robotically, using the da Vinci Surgical System (Intuitive Surgical). The bladder was entrapped in an Endocatch bag and removed through a small subumbilical incision. Urinary reconstruction was performed extracorporeally after exteriorizing the bowel through the incision used for retrieving the specimen. In two patients, the reconstructed pouch was placed in the pelvis and the abdominal incision was closed. Urethroneovesical anastomosis was done robotically, using a technique described previously for men. RESULTS The average operating time for the robotic radical cystectomy was 160 minutes and the mean operating times for ileal conduit and orthotopic neobladder were 130 minutes and 180 minutes, respectively. The mean blood loss was less than 100 mL. The mean number of lymph nodes removed was 12 (range 3 to 21). Surgical margins were free of tumor in all three patients. CONCLUSIONS This approach incorporates advantages of minimally invasive and open surgery. Performing the radical cystectomy with the robot allows precise and rapid removal of the bladder with minimal blood loss. Extracorporeal reconstruction of the urinary tract reduces operative time at this stage of evolution of laparoscopic and robotic instrumentation. In the future, with the development of technology, instrumentation, and with additional refinement of our technique, the entire procedure may be done completely intracorporeally with equal efficiency.

Abstract
BACKGROUND Laparoscopic extended lymph node dissection for gastric cancer is difficult to perform because it requires dissection with preservation of vessels. Therefore, an intraoperative navigation system for the angioarchitecture would be helpful. Recent enhanced volume-rendering computed tomography (CT) can produce clear intraluminal three-dimensional (3D) images. This advanced radiological technology can provide 3D angiographic images reconstructed in the same view as would be observed from a laparoscope inserted into the abdominal cavity. We report our experience with laparoscopic gastrectomy with radical lymph node dissection using this advanced radiological technology. METHODS 3D CT angiographic images from the celiac axis to the proper hepatic artery were reconstructed in two ways preoperatively. The first was only 3D angiographic images that were reconstructed as the laparoscopic view (LapView 3D CT angiography). The second was LapView 3D CT angiography with images of the body of the pancreas, which was more useful for intraoperative navigation in comprehensing anatomy. Two monitors were placed over the shoulder of the patient during surgery. One monitor, which was controlled by the image mixer, projected the laparoscopic images with picture in picture of 3D CT angiographic images. The surgeon performed the surgery with reference to this monitor during lymph node dissection. RESULTS 3D angiographic CT clearly showed all vessels of interest in laparoscopic lymph node dissection for gastric cancer in 10 cases. The anatomy of vessels appeared as if looking beyond visible surface. LapView 3D CT angiography was useful for laparoscopic navigation surgery.

Abstract
This paper describes a new surgical technique and our clinical experience with video-assisted endoscopic total glandectomy via a middle axillary incision followed by immediate reconstruction with latissimus dorsi muscle flap (LDMF) performed in 17 patients with bigger, multiple tumors or extensive ductal spread of breast cancer. The novel techniques in this procedure are as follows: (1) By securing patients in a semi-lateral position and suspending the upper extremity, either supine or semi-lateral position can be easily achieved by simply rotating the operating table, resulting in a wider working space from the axillary to hip area. (2) By applying a retractor for skin flap traction, endoscopic glandectomy and reconstruction become safe and reliable. As a result, the mean number and size of tumors were 1.2 and 4.12 cm, respectively. Surgical margins of all the cases were pathologically negative and there were no recurrences observed during 14 months follow-up to date. Esthetic results have been satisfactory and the surgical wounds were not visible from the front in any case. Compared to mastectomy, this procedure shows the same therapeutic results, but offers a greater esthetic and psychological advantage to all the patients.

Abstract
BACKGROUND/AIMS From the experience of laparoscopic-assisted distal gastrectomy, it was considered that a gastrectomy with lymph node dissection could be performed through a minilaparotomy, placed as for gastroduodenostomy in laparoscopic-assisted distal gastrectomy. METHODOLOGY Ten patients with early gastric cancer underwent gastrectomy with lymph node dissection via minilaparotomy. Minilaparotomy was performed via a seven-centimeter midline incision placed at the mid-upper abdomen. Two six-centimeter-wide Kent retractors were used to suspend the abdominal wall on each side, and a multipurpose surgical arm to retract the liver. The abdominal wound could be moved horizontally by pulling these retractors to the right or left. This movable wound allowed direct visualization of almost all the operative field for gastrectomy. RESULTS No operation was converted to a standard open gastrectomy. The patients who had a tumor in the lower third of the stomach underwent complete D2 lymph node dissection. In the patients who underwent pylorus-preserving gastrectomy, near complete D2 lymph node dissection was performed. Mean operation time was 175 minutes. No significant complication was encountered. CONCLUSIONS It was concluded that minilaparotomy could be used as an alteration to the standard open gastrectomy.

Abstract
OBJECTIVES Robotic radical prostatectomy is a new procedure for treating prostate cancer. Many centers are attempting this new modality but a detailed description of the technique has not yet been published. We report the technique as performed at the Vattikuti Urology Institute. METHODS At Vattikuti Urology Institute, we have performed more than 30 such operations and have standardized the technique for safe and reproducible treatment of prostate cancer. We collected the patient data and surgical logs to improve and standardize this procedure. We recorded the operation and made relevant modifications after reviewing the recordings to improve the outcome. RESULTS The operation was developed on the scientific foundations of anatomic radical prostatectomy as described by Walsh and the laparoscopic prostatectomy developed at Montsouris. Our technique differs from these procedures because of the need for two surgical teams and the use of fine, endo-wrist instruments with three-dimensional stereoscopic visualization. We describe the patient setup, positioning, port placement, preparation of the robot, docking of the arms, and the surgical steps of performing anatomic prostatectomy with robotic assistance. CONCLUSIONS This report describes the current technique of robotic prostatectomy as developed at the Vattikuti Urology Institute.

Abstract
OBJECTIVES To analyse the experience of our own group and other reference groups with laparoscopic pelvic lymphadenectomy since 1990 regarding different aspects: Technical details, results, complications, and establishment of its current indications for prostate cancer treatment. METHODS We report a retrospective statistical analysis of a series of lymphadenectomies over a 10 year period with a total of 202 cases (69 laparoscopic and 133 open surgical) analysing different lymph node invasion risk factors. RESULTS Elevated PSA and Gleason resulted in more lymph node infiltration being the cutting point in 40 and 7 respectively. CONCLUSIONS Laparoscopic lymphadenectomy provides equal diagnostic reliability than the traditional technique. Currently we perform laparoscopic lymphadenectomy in prostate cancer for T3 tumours (independently of PSA or Gleason score) and in < T3 with PSA > or = 40, Gleason > or = 8, and in cases with Gleason 7 and PSA > 20.

Abstract
OBJECTIVES Primary objective of the present article is to evaluate the surgical efficiency of the laparoscopic retroperitoneal lymph node dissection in clinical stage I and II testis tumor. Secundary, objective is the description of the technique used by the author. METHODS A description of the author's experience and review of the literature in terms of feasibility, oncological results and quality of life. RESULTS Once the learning curve has been overcome, the operative time is in the range of that open surgery with lower morbidity and complications. Ejaculation can be preserved in virtually all patients by means of a template dissection. With a mean follow-up of almost four years oncologic long-term outcome is not compromised by the laparoscopic approach. CONCLUSIONS In clinical stage I testis tumor laparoscopic retroperitoneal lymph node dissection can be used as a diagnostic measure with the same long term results as the open procedure. In stage II disease removal of residual tumor can also be achieved by laparoscopy.

Abstract
OBJECTIVE To compare the morbidity of conventional inguinal lymphadenectomy for epidermoid carcinoma of the penis using ligation versus ultrasonic sealing of the lymph nodes with Ligasure. METHODS 29 cases of carcinoma of the penis are analyzed; 8 underwent superficial and deep inguinal lymphadenectomy using the conventional procedure for ligation of lymph nodes (4 cases) and ultrasonic ligation with Ligasure (4 cases). The early and late complications are analyzed. RESULTS The operating time was found to be significantly shorter in patients treated with Ligasure, no lymphoceles were observed and lymphedema was reduced. CONCLUSIONS The use of Ligasure for sealing the lymphatic vessels in inguinal lymphadenectomy for carcinoma of the penis appears to have the advantages of a shorter operating time and reduced complications in comparison with conventional ligation.

Abstract
Exact pretherapeutic lymph node staging of lung cancer is of special importance for selecting patients for neoadjuvant therapy or for video-assisted thoracoscopic resection. Staging is usually performed by computerized tomography scan and mediastinoscopy. However, these methods do not reach the accuracy of open nodal dissection. Therefore, we developed a technique of radical video-assisted mediastinoscopic lymphadenectomy (VAMLA). In a prospective study, all VAMLA procedures were documented. Lymph nodes were counted and compared to open lymphadenectomy. In 40/46 patients, radical paratracheal and subcarinal dissection was achieved by VAMLA. An average number of 20.7 (5-60, SD 11.1) nodes was gained. This is comparable to our data from open lymphadenectomy.

Abstract
Gastrectomy, followed by extended lymphadenectomy, is the treatment of choice in some stages of advanced gastric cancer. Lymphorrhea, as a result of the many divided lymphatic vessels, increases the morbidity. Ultrasonically activated coagulated shears (UACS) may divide all small vessels followed by immediate sealing of the coapted vessel walls. We designed a prospective randomized study to determine the effectiveness of the UACS versus monopolar electrosurgery in D2 dissection. Forty patients with gastric cancer stage II or stage IIIA were enrolled and randomized into 2 groups of 20 patients each. Group A underwent lymphatic dissection with monopolar cautery. Group B underwent lymphatic dissection with UACS. Subhepatic and left sudiaphragmatic closed drains were left until lymphorrhea and/or oozing stopped. Total gastrectomy was performed in 16 patients of group A and 14 of group B; subtotal gastrectomy was performed in 4 patients in group A and 6 patients in group B. The drains were removed after 6-17 days (mean 9.7 +/- 2.9) in group Aand after 4-8 days (mean 5.6 +/- 1.2) in group B(p < 0.001). The total amount of drained fluid was 300-2050 ml (mean 985 +/- 602) in group A and 230-1080 ml (mean 480 +/- 242) in group B (p < 0.002). Eight patients in group A and 5 in group B had postoperative fever, while 3 and 1 patients, respectively, had wound infections. In conclusion the use of UACS is a safe method of lymphatic dissection which reduces operative blood loss, postoperative lymphorrhea, blood transfusions,and hospital stay.

Abstract
BACKGROUND The purpose of this study was to evaluate the safety and efficacy of endoscopic axillary lymphadenectomy using needlescopic instruments in patients with breast cancer. METHODS Five patients with breast cancer were treated by partial mastectomy and endoscopic axillary lymphadenectomy. We evaluated the results of the surgical procedure and the postoperative course. RESULTS In all the patients, endoscopic axillary lymphadenectomy was performed successfully. The mean duration of the operation was 105.4 min, the mean blood loss 19.4 ml, and the mean number of dissected axillary lymph nodes 13. There were no intra- or postoperative complications. The mean amount of lymphorrhea was 131.2 ml, and the mean duration of drainage was 3.6 days. No postoperative analgesics were administered. CONCLUSIONS Endoscopic axillary lymphadenectomy can be performed safely with needlescopic instruments, but further study is needed to establish this technique.
