    Omental infarction occurring after open and laparoscopic-assisted distal gastrectomy with partial omentectomy for gastric cancer was a very rare disease in the past, but its incidence has increased as more partial omentectomies are now being performed. But there are few case reports or radiologic studies on its increasing incidence. It is necessary to differentiate omental infarction from carcinomatosis peritonei, since both have similar imaging findings. In this report, we describe two cases of omental infarction; each occurred after open and laparoscopic-assisted distal gastrectomy in early gastric cancer patients. Partial omentectomy was performed in both cases. Omental infarction following distal gastrectomy with partial omentectomy can be discriminated from carcinomatosis peritonei by comparing with different initial and follow up CT findings.

    Objective: To describe the clinical characteristics, indications, technical procedures, and outcome of a consecutive series of laparoscopic distal pancreatic resections performed by the same surgical team. Summary Background Data: Laparoscopic distal pancreatic resection has increasingly been described as a feasible and safe procedure, although accompanied by a high rate of conversion and morbidity. Methods: A consecutive series of patients affected by solid and cystic tumors were selected prospectively to undergo laparoscopic distal pancreatectomy performed by the same surgical team. Clinical characteristics as well as diagnostic preoperative assessment and intra- and postoperative data were prospectively recorded. A follow-up of at least 3 months was available for all patients. Results: Fifty-eight patients underwent laparoscopic resection between May 1999 and November 2005. All procedures were successfully performed laparoscopically, and no patient required intraoperative blood transfusion. Splenic vessel preservation was possible in 84.4% of spleen-preserving procedures. There were no mortalities. The overall median hospital stay was 9 days, while it was 10.5 days for patients with postoperative pancreatic fistulae (27.5% of all cases). Follow-up was available for all patients. Conclusions: Our experience in 58 consecutive patients was characterized by the lack of conversions and by acceptable rates of postoperative pancreatic fistulae and morbidity. Laparoscopy proved especially beneficial in patients with postoperative complications as they had a relatively short hospital stay. Solid and cystic tumors of the distal pancreas represent a good indication for laparoscopic resection whenever possible. PMID:17592294

    Laparoscopic assisted cholecystostomy (LAC) is a safe method for external biliary drainage in jaundiced patients with distal common bile duct obstruction. It consists of the retrieval of the fundus of the gallbladder through the trocar, thus through abdominal wall followed by suture to the skin. This technique could be an option for surgeons who manage a patients with jaundice by distal common bile duct obstruction.

    During the last two years, reports on laparoscopic procedures of the pancreas have been on increase. Laparoscopic resection of the pancreatic cauda is indicated, primarily, for benign cystic lesions of the cauda of the pancreas and for neuroendocrine tumors of the pancreas (mainly insulinomas). We have not recorded any report on the above procedure in the Czech literature. Therefore, in our case review, we have described laparoscopic distal resection of the pancreas with splenectomy for a pseudopapillary tumor of the pancreas.

    Aims Laparoscopic distal pancreatectomy is becoming a more commonly used procedure, which may involve the use of four to seven ports, depending on the technique. Initial data on feasibility, safety and outcome with the three-port laparoscopic distal pancreatectomy are presented. Methods The patient is placed in a partial thoracoabdominal position exposing the left flank in a reverse Trendelenberg position. A 10-mm Hassan trocar is inserted through a subcostal anterior axillary incision. A 5-mm midclavicular and 10-mm posterior axillary line trocar are placed. The specimen is retrieved from the anterior axillary line port. Results Ten women and seven men, aged 26–88 years (mean 61 years), were evaluated. Their body mass indexes ranged from 18–37 (mean 27). Pancreatic lesion size ranged from 1.0–5.5 cm (mean 3.0 cm). Operative time was 116–296 min (mean 170 min). Blood loss was 10–300 ml (mean 142 ml). No operation required conversion or additional trocar placement. Post-operative stay was 2–7 days (mean 4 days). No patient developed a pancreatic fistula. Conclusion Operative time, blood loss and post-operative stay of this three-port technique compare favourably with published data. PMID:21492337

    To report the initial experience with the laparoscopy-assisted distal gastrectomy (LADG) with D2 lymphadenectomy for gastric cancer. Between May 2006 and May 2007, 29 consecutive GC patients with gastric cancer underwent LADG with D2 lymphadenectomy. The operation consisted in a laparoscopic time to perform lymphadenectomy and mobilization of the distal stomach, followed by a minilaparotomy for exteriorization of the specimen and construction of a hand sewn anastomosis. Twenty-nine patients underwent LADG with D2 lymphadenectomy for gastric cancer. Mean age was 58.2 years. Mean operative time was 287.4 min. Mean number of lymph nodes resected was 42.6. Twelve patients were early gastric cancer, and seventeen were advanced gastric cancer. Mean proximal and distal resection margin were 5.8 cm and 3.5 cm, respectively. Resection margins were negative in all cases. Mean number of lymph nodes resected was 42.6. Thirty-day morbidity rate was 10.3 %. There were no postoperative deaths.CONCLUSION. The short-term results of our LADG with D2 lymphadenectomy for the treatment of gastric cancer shows that a radical surgery, in terms of resection margins and lymphadenectomy, can be done with low morbidity.

    Full Text Available To compare the safety and efficacy of robotic-assisted distal pancreatectomy (RADP and laparoscopic distal pancreatectomy (LDP.A literature search of PubMed, EMBASE, and the Cochrane Library database up to June 30, 2015 was performed. The following key words were used: pancreas, distal pancreatectomy, pancreatic, laparoscopic, laparoscopy, robotic, and robotic-assisted. Fixed and random effects models were applied. Study quality was assessed using the Newcastle-Ottawa Scale.Seven non-randomized controlled trials involving 568 patients met the inclusion criteria. Compared with LDP, RADP was associated with longer operating time, lower estimated blood loss, a higher spleen-preservation rate, and shorter hospital stay. There was no significant difference in transfusion, conversion to open surgery, R0 resection rate, lymph nodes harvested, overall complications, severe complications, pancreatic fistula, severe pancreatic fistula, ICU stay, total cost, and 30-day mortality between the two groups.RADP is a safe and feasible alternative to LDP with regard to short-term outcomes. Further studies on the long-term outcomes of these surgical techniques are required.To date, there is no consensus on whether laparoscopic or robotic-assisted distal pancreatectomy is more beneficial to the patient. This is the first meta-analysis to compare laparoscopic and robotic-assisted distal pancreatectomy. We found that robotic-assisted distal pancreatectomy was associated with longer operating time, lower estimated blood loss, a higher spleen-preservation rate, and shorter hospital stay. There was no significant difference in transfusion, conversion to open surgery, overall complications, severe complications, pancreatic fistula, severe pancreatic fistula, ICU stay, total cost, and 30-day mortality between the two groups.

    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.

    Pancreatic surgery represents one of the most challenging areas in digestive surgery.In recent years,an increasing number of laparoscopic pancreatic procedures have been performed and laparoscopic distal pancreatectomy (LDP) has gained world-wide acceptance because it does not require anastomosis or other reconstruction.To date,English literature reports more than 300 papers focusing on LDP,but only 6% included more than 30 patients.Literature review confirms that LDP is a feasible and safe procedure in patients with benign or low grade malignancies.Decreased blood loss and morbidity,early recovery and shorter hospital stay may be the main advantages.Several concerns still exist for laparoscopic pancreatic adenocarcinoma excision.The individual surgeon determines the technical conduction of LDP,with or without spleen preservation;currently robotic pancreatic surgery has gained diffusion.Additional researches are necessary to determine the best technique to improve the procedure results.

    Full Text Available Aim: To assess the modifications in the technique of laparoscopic assisted anorectal pull through (LAARP practiced at our institute and analyze the post operative outcome and associated complications. Materials and Methods: A retrospective study from January 2001 to May 2009 analyzing LAARP for high anorectal malformations. Results: A total of 40 patients - 34 males and six females, in the age group of two months to six years were studied. Staged procedure was done in 39 patients; one child with recto vestibular fistula underwent single stage procedure. All the patients withstood surgery well. One patient required conversion due to problems in gaining enough length for the distal rectum in a patient with rectovesical fistula so colostomy was closed and re-located at a proximal splenic flexure. The complications were mucosal prolapse (six cases, anal stenosis (three, adhesive obstruction (two, distal rectal necrosis (one, and urethral diverticulum (one. The patients were followed up with clinical evaluation and continence scoring. The progress has been satisfactory and weight-gain is adequate. Conclusions: The advantages of the reformed techniques are as follows: Transcutaneous bladder stitch provides excellent visualization; traction over the fistula helps in dissection of the puborectalis, dividing the fistula without ligation is safe, railroading of Hegar′s dilators over the suction canula creates adequate pull through channel, saves time and makes procedure simpler with reproducible comparable reports.

    Introduction. Laparoscopic radical nephroureterectomy (LNU) is being increasingly performed at several centers across the world. We review oncologic outcomes after LNU procedure and the techniques for the management of distal ureter. Materials and Methods. A comprehensive review of the literature was performed on the oncological outcomes and management of distal ureter associated with LNU for upper tract transitional cell carcinoma (TCC). Results and Discussion. LNU for upper tract TCC is performed pure laparoscopically (LNU) or hand-assisted (HALNU). The management of the distal ureter is still debated. LNU appears to have superior perioperative outcomes when compared to open surgery. Intermediate term oncologic outcomes after LNU are comparable to open nephroureterectomy (ONU). Conclusions. Excision of the distal ureter and bladder cuff during nephroureterectomy remains controversial. Intermediate term oncologic outcomes for LNU compare well with ONU. Initial long-term oncologic outcomes are encouraging. Prospective randomized comparison between LNU and open surgery is needed to define the role of these modalities in the current context.

    Full Text Available Introduction: Minimally invasive surgery has revolutionized general surgery during the past 10 years. However, for more advanced surgical procedures, the acceptance of the minimally invasive approach has been slower than expected. Advanced laparoscopic surgery is complex and time-consuming. The major drawbacks of laparoscopic surgery are two-dimensional view, lack of depth perception and loss of tactile sensation. This has led to the innovation of hand-assisted laparoscopic surgery (HALS. The objective of the present study was to determine that safety of HALS. Materials and Methods: We preformed 18 HALS procedures in our department between July 2003 and January 2005 on patients who had given their informed consent for the use of Gelport. Out of these, 15 were colectomy, 2 nephrectomy and 1 splenectomy. Out of the 18 patients, 13 were males and 5 were females with the age group ranging from 44 to 72 years. Results: Hand-assisted laparoscopic surgery could be completed in 17 patients maintaining all the oncological principals of surgery. The mean operating times were 120 min for right haemicolectomy, 135 min for left colectomy, 150 min for splenectomy, and 150 min for nephrectomy. The patient undergoing radical nephrectomy by HALS had to be converted to open surgery. As the tumour was large and adherent to the spleen and posterior peritoneal wall. Postoperative recovery was excellent with an average hospital stay of 5 days. Histopathology report showed wide clearance and till date we have a good follow up of 30-380 days. Conclusion: Hand-assisted laparoscopic surgery allows tactile sensation and depth perception thereby may simplify the complex procedures. This may result in reduction of operating time and conversion rates at the same time maintaining all the oncological principles. Hand-assisted laparoscopic surgery strikes a perfect balance between an extended open laparotomy incision and an excessively tedious laparoscopic exercise. Hand

    Full Text Available Background Ramstedt pyloromyotomy is the procedure of choice for infantile hypertrophic pyloric stenosis; however, the best way to approach the pylorus is debated. Recent literature reports many comparisons between various open and laparoscopic approaches. The purpose of this experience is to show a new approach to infantile hypertrophic pyloric stenosis: single-port, laparoscopic-assisted pyloromyotomy. Methods: 31 infants underwent single-port laparoscopic-assisted pyloromyotomy. The approach to the abdominal cavity is performed through a right circumbilical incision, and then a 12-mm trocar is inserted. After the pneumoperitoneum is established, an operative telescope is introduced. Once the telescope is inserted, the pylorus is easily located, and then grasped and exteriorized via the umbilical incision. At this point, conventional Ramstedt pyloromyotomy is performed. Once the pylorus is reintroduced in the abdomen, a new pneumoperitoneum is created to control mucosal integrity and hemostasis. Results. In all 31 cases operated on, an adequate pyloromyotomy was performed in a good ranging time without any intra- or post-operative complications, achieving also excellent cosmetic results. Conclusions The feasibility of single-port laparoscopic assisted pyloromyotomy obtained in this small sample suggests that this procedure could be an excellent alternative to open or laparoscopic pyloromyotomy as long as it acts as intermediary between the two techniques.

    Full Text Available Some of the patients with genitourinary tuberculosis (GUTB present to the urologist with small contracted bladders or with significant renal damage. [1] Additional reconstructive procedures are often required along with anti-tubercular treatment in these patients. These procedures commonly performed via the open approach, now have the advantage of minimally invasive approach provided by laparoscopic and robotic surgery. The technique of robot-assisted laparoscopic augmentation ileocystoplasty in a patient with a small contracted bladder due to GUTB will be described. The procedure was performed via a completely intra-corporeal technique using an ileal "cap" created from a 15 cm segment of distal ileum which was anastomosed to the urinary bladder bi-valved in the mid-sagittal plane. The procedure lasted for 420 minutes and the patient was discharged on postoperative day 5. At 6 month follow-up, the patient has no irritative urinary symptoms and voiding with insignificant post-void residual urine.

    Objects We have developed a new MR-compatible laparoscope that incorporates a distally mounted charge-coupled device (CCD). The MR-compatibility and feasibility of laparoscopy using the new laparoscope were evaluated during MR image-guided laparoscopic radiofrequency ablation therapy (RFA). Materials and methods MR compatibility of the laparoscope was investigated in terms of MR image artifact caused by electromagnetic interference (EMI) and susceptibility. MR images were obtained using spin echo and gradient echo pulse sequences with a 0.3 T open MRI unit. We performed an in vivo experiment with MR image-guided laparoscopic RFA on three pigs; near real-time MR images and 3-D navigation were possible using intraoperative MR images. Agarose gel was injected into the pigs' livers as puncture targets; the diameter of each target was approximately 20 mm. Results Artifacts resulting from EMI were not found in phantom experiments. MR image-guided laparoscopic RFA was successfully performed in all procedures. Both the laparoscopic vision and near real-time MR images were clear. No artifact was detected on the MR images and the surgeon was able to confirm the true position of the probe and target during treatment using the near real-time MR images. Conclusion Laparoscopic surgery is feasible under intraoperative MR image-guidance using a newly developed MR-compatible laparoscope with a distally mounted CCD. (orig.)

    2009-01-01

    Laparoscopic nephroureterectomy (LNU) is becoming an increasingly common alternative treatment for transitional cell carcinoma (TCC) of the renal pelvis and ureter due to decreased perioperative morbidity, shorter hospitalization, and comparable oncologic control with open nephroureterectomy (ONU). Mobilization of the kidney and proximal ureter may be performed through a transperitoneal, retroperitoneal, or hand-assisted approach. Each technique is associated with its own benefits and limitations, and the optimal approach is often dictated by surgeon preference. Our analysis of the literature reflects equivalent cancer control between LPN and OPN at intermediate follow-up with significantly improved perioperative morbidity following LPN. Several methods for bladder cuff excision have been advocated, however, no individual technique for management of the distal ureter proved superior. Overall, complete en-bloc resection with minimal disruption of the urinary tract should be optimized to maintain oncologic outcomes. Longer follow-up and prospective studies are needed to fully evaluate these techniques. PMID:19148293

    Abstract Background: The distal splenorenal shunt is an effective procedure for the treatment of portal hypertension in children. However, there has been no report about laparoscopic distal splenorenal shunt in the treatment of portal hypertension in children. Methods: From December 2015 to August 2016, 4 children with upper gastrointestinal bleeding underwent laparoscopic distal splenoadrenal shunt. Portal hypertension and splenomegaly were demonstrated on the preoperative computed tomography (CT) and sonography. The distal splenic vein was mobilized and anastomosed to the left adrenal vein laparoscopically. All patients were followed-up postoperatively. Results: The laparoscopic distal splenoadrenal shunt was successfully performed in all patients. The liver fibrosis was diagnosed by postoperative liver pathology. The operative time ranged from 180 to 360 minutes. The blood loss was minimal. The length of hospital stay was 6 to 13 days. The duration of following-up was 1 to 9 months (median: 3 months). The portal pressure and splenic size were decreased postoperatively. The complete blood count normalized and the biochemistry tests were within normal range after surgery. Postoperative ultrasound and CT confirmed shunt patency and satisfactory flow in the splenoadrenal shunt in all patients. No patient developed recurrence of variceal bleeding. Conclusions: The laparoscopic splenoadrenal shunt is a feasible treatment of portal hypertension in children. PMID:28099341

    In the surgical treatment of gastric cancer, obesity is known to be a predictive factor for poor early surgical outcomes. To evaluate the more effective modality of laparoscopic gastrectomy in obese patients, we compared the early surgical outcomes of laparoscopy-assisted and totally laparoscopic gastrectomy. We retrospectively analyzed early surgical outcomes in 1,480 consecutive patients who underwent distal gastrectomy for gastric cancer between April 2004 and July 2010. To compare surgical outcomes of laparoscopy-assisted distal gastrectomy (LADG) with those of totally laparoscopic distal gastrectomy (TLDG) in 76 obese patients (LADG, n = 39; TLDG, n=37), the patients were classified as either obese or nonobese. The obesity was defined using the WHO classification BMI cutoff of 30 kg/m2. In the analysis of surgical outcomes of the LADG group, there were significant differences between the obese and nonobese groups with respect to operative time (P=0.004, obese, 171.8 min; nonobese, 141.0 min), time to first flatus (P=0.027, obese, 3.3 days; nonobese, 3.1 days), commencement of soft diet (P=0.040, obese, 4.6 days; nonobese, 4.0 days), postoperative complication rate (P=0.045, obese, 15.4%; nonobese, 6.5%), and postoperative hospital stay (P=0.014, obese, 8.9 days; nonobese, 7.2 days). In TLDG group, on the other hand, there were no significant differences in surgical outcomes between the groups. Based on these findings, early surgical outcomes of LADG were strongly influenced by the obesity. TLDG without minilaparotomy, however, was unaffected by the obesity. These findings strongly suggest that TLDG could be a safe procedure to avoid the impact of obesity.

    Full Text Available Background: A laparoscopic surgery can be beneficial in a spleen-preserving distal pancreatectomy. Aims: This report shows a 60-year-old woman who presented to her persistent upper abdominal and bilateral lumbodorsal distending pain for one year. A computed tomography scan demonstrated a 4cm×5cm×5cm solid space-occupying mass in the distal pancreas. The patient was referred to minimally invasive surgery service for resection of the pancreatic lesion. Methods: A laparoscopic spleen-preserving distal pancreatectomy was performed. Results: The mass was completely excised, the pathological examination revealed pancreatic adenocarcinoma with grade II. The postoperative advantages of this approach were the early return of bowel function, minimal complications, and early resumption of normal activities. Conclusions: This case illustrates that minimally invasive surgery in the performance of a spleen-and-splenic-vessel preserving distal pancreatectomy is a feasible procedure without compromising the splenic function.

    Gallstone ileus is a rare complication of cholelithiasis seen usually in elderly population with comorbidities. Most of the cases present as acute intestinal obstruction with the diagnosis being made intraoperatively. There exists controversy regarding appropriate emergency surgical treatment of gallstone ileus as to whether biliary tract surgery should be done during the first operation. Laparoscopy in recent years is also being used for management of such cases. We report a case of gallstone ileus diagnosed preoperatively and successfully treated by laparoscopic-assisted enterolithotomy.

    The adoption of robotic systems for gastric cancer surgery has been proven feasible and safe; however, a benefit over the laparoscopic approach has not yet been well-documented. We aimed to investigate the surgical outcomes of robotic versus laparoscopic gastrectomy for gastric cancer, according to the extent of surgery and patients' obesity status. Between January 2009 and July 2011, 770 patients were enrolled in this retrospective analysis. All had stage IA/IB gastric cancer preoperatively and underwent either laparoscopic (n = 622) or robotic (n = 148) gastrectomy. Patients were classified into obese and non-obese groups on the basis of visceral fat area (VFA). The extent of surgery was defined by whether patients underwent distal or total gastrectomy. The surgical outcomes following distal gastrectomy were similar between the robotic and laparoscopic groups regardless of the obesity status. After total gastrectomy, the number of total and N2-area lymph nodes were significantly higher in the robotic group than in the laparoscopic group in non-obese patients with VFA obese population. Robotic group developed less severe complications after total gastrectomy compared to laparoscopic group in non-obese patients (p = 0.036). Robotic assistance did not improve surgical outcomes over the laparoscopic approach in obese patients undergoing distal gastrectomy. However, non-obese patients with low VFA may benefit from robotic assistance during total gastrectomy in terms of radical D2 lymphadenectomy with fewer serious complications.

    Full Text Available Solid pseudopapillary neoplasm (SPN is a rare tumor of the pancreas. Laparoscopic distal pancreatectomy (DP is a feasible and safe procedure, and successful spleen preservation rates are higher using a laparoscopic approach. We hypothesized that certain patients with SPN would be good candidates for laparoscopic surgery; however, few surgeons have reported laparoscopic DP for SPN. We discuss the preoperative assessment and surgical simulation for two SPN cases. A simulation was designed because we consider that a thorough preoperative understanding of the procedure based on three-dimensional image analysis is important for successful laparoscopic DP. We also discuss the details of the actual laparoscopic DP with or without splenic preservation that we performed for our two SPN cases. It is critical to use appropriate instruments at appropriate points in the procedure; surgical instruments are numerous and varied, and surgeons should maximize the use of each instrument. Finally, we discuss the key techniques and surgical pitfalls in laparoscopic DP with or without splenic preservation. We conclude that experience alone is inadequate for successful laparoscopic surgery.

  13. Techniques to resect the distal ureter in robotic/laparoscopic nephroureterectomy

    2016-07-01

    Full Text Available Treatment of clinically-organ confined high grade urothelial carcinoma of the upper tract has historically comprised open nephroureterectomy, with the distal ureter and bladder cuff mobilized through a separate open pelvic incision. To decrease morbidity, urologists have increasingly adopted laparoscopy and robotics in performing nephroureterectomy. In many published series of laparoscopic nephroureterectomy, the distal ureter and bladder cuff are detached from the bladder endoscopically by a variation of the “pluck” technique, with the resulting bladder defect left to heal by prolonged indwelling urethral catheter drainage. While the distal ureter and bladder cuff can be excised laparoscopically, it does require advanced laparoscopic skills. With the wrist articulation and stereoscopic vision in robotic surgery, robotic nephroureterectomy (RNU and bladder cuff excision can be performed in antegrade fashion to mimic the open technique together with the ability to intracorporeally close the bladder defect in a watertight, mucosa to mucosa fashion after excising the bladder cuff. In this review, we discuss the published minimally invasive techniques in resecting the distal ureter and bladder cuff during laparoscopic and RNU.

    Laparoscopic pyeloplasty as a treatment for ureteropelvic junction obstruction has shown comparable success rates with open pyeloplasty techniques. The use of robotic technology to assist during laparoscopic pyeloplasty procedures has been encouraged by the steep learning curve for laparoscopic surgical skills, and the complexity of laparoscopic suturing. Robotic technology provides the surgeon with the ability to filter out any physiologic hand tremor, more degrees of freedom of movement than traditional laparoscopic instruments, the ability to scale movement to provide better control for microsurgery, better ergonomics during surgery, and three-dimensional vision. Details of the procedure and specific nursing care of the patient undergoing robotic-assisted laparoscopic pyeloplasty at the University of Iowa Hospital and Clinics are described.

    Full Text Available To report our experience of pure laparoscopic and robot-assisted laparoscopic reconstructive surgery in congenital megaureter, seven patients (one bilateral with symptomatic congenital megaureter underwent pure laparoscopic or robot-assisted laparoscopic surgery. The megaureter was exposed at the level of the blood vessel and was isolated to the bladder narrow area. Extreme ureter trim and submucosal tunnel encapsulation or papillary implantations and anti-reflux ureter bladder anastomosis were performed intraperitoneally by pure laparoscopic or robot-assisted laparoscopic surgery. The clinical data of seven patients after operation were analyzed, including the operation time, intraoperative complications, intraoperative bleeding volumes, postoperative complications, postoperative hospitalization time and pathological results. All of the patients were followed. The operation was successfully performed in seven patients. The mean operation times for pure laparoscopic surgery and robotic-assistant laparoscopic surgery were 175 (range: 150-220 and 187 (range: 170-205 min, respectively, and the mean operative blood loss volumes were 20 (range: 10-30 and 28.75 (range: 15-20 ml, respectively. There were no intraoperative complications. The postoperative drainage time was 5 (range: 4-6 and 5.75 (range: 5-6 d, respectively, and the indwelling catheter time was 6.33 (range: 4-8 d and 7 (range: 7-7 d, respectively. The postoperative hospitalization time was 7.67 (range: 7-8 d and 8 (range: 7-10 d, respectively. There was no obvious pain, no secondary bleeding and no urine leakage after the operation. Postoperative pathology reports revealed chronic urothelial mucosa inflammation. The follow-up results confirmed that all patients were relieved of their symptoms. Both pure laparoscopic and robot-assisted laparoscopic surgery using different anti-reflux ureter bladder anastomoses are safe and effective approaches in the minimally invasive treatment of

    Full Text Available ABSTRACT The role of laparoscopy in the modern surgery era is well established. With the prospect of being able to improve the already privileged current situation, new alternatives have been proposed, such as natural orifice endoscopic surgery (NOTES, the method for single transumbilical access (LESS - Laparo-endoscopic single-site surgery and minilaparoscopy (MINI. The technique proposed by the authors uses a laparoscope with an operative channel like the flexible endoscope used in NOTES. All operative times are carried out through the umbilical trocar as in LESS, and assisted by a minilaparoscopy grasper. This new technic combines, and results from, the rationalization of technical particularities and synergy of these three approaches, seeking to join their advantages and minimize their disadvantages.

    Full Text Available Gastric leakage postsurgery is the most feared complication of laparoscopic sleeve gastrectomy due to the difficulty of its management. While gastric leakagemanagement postsurgery is often performed using internal drainage catheters accompanied by self-expandable metal stents, endoscopic internal drainage by double pigtail catheter has recently become a recommended approach. Here we describe our treatment of a patient who experienced distal gastric leakage after undergoing laparoscopic sleeve gastrectomy using double pigtail catheter and our treatment recommendations based on the patient outcome.

    The aim of this study is to estimate the impact of obesity on surgical outcomes of laparoscopic-assisted gastrectomy for gastric cancer. Between January 2005 and January 2010, 1100 consecutive patients who underwent laparoscopic-assisted distal gastrectomy for gastric cancer were reviewed to evaluate the impact of obesity. The patients were classified into 3 groups according to the World Health Organization classification, as normal weight [body mass index (BMI) 18.5 to 24.9 kg/m], overweight (BMI 25 to 29.9 kg/m), and obese patients (BMI ≥30 kg/m). The postoperative complication rates for normal weight, overweight, and obese patients were 5.7%, 10.0%, 15.4%, respectively. Overweight and obese patients had a significantly prolonged operation time, increased intraoperative blood loss, prolonged first flatus, day of commencement of soft diet, increased number of administration of analgesics, and prolonged hospital stay. Overweight and obesity were associated with poor early surgical outcomes of laparoscopic-assisted gastrectomy. This study suggested that greater cautions and improved surgical techniques were required to improve early surgical outcomes of laparoscopic-assisted gastrectomy for overweight and obese patients.

    Laparoscopic resection of rectal cancer or gastric cancer has been advocated for the benefits of a reduced morbidity, a shorter treatment time, and similar outcomes. However, simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy for synchronous carcinoma of rectum and stomach are rarely documented in literature. Endoscopic examination revealed a synchronous carcinoma of rectum and stomach in a 55-year-old male patient with rectal bleeding and epigastric discomfort. He underwent a simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy with regional lymph nodes dissected. The operation time was 270 min and the estimated blood loss was 120 mL. The patient required parenteral analgesia for less than 24 h. Flatus was passed on postoperative day 3, and a solid diet was resumed on postoperative day 7. He was discharged on postoperative day 13. With the advances in laparoscopic technology and experience, simultaneous resection is an attractive alternative to a synchronous gastrointestinal cancer.

    Laparoscopic surgery is applied today worldwide to most digestive procedures. In some of them, such as cholecystectomy, Nissen’s fundoplication or obesity surgery, laparoscopy has become the standard in practice. In others, such as colon or gastric resection, the laparoscopic approach is frequently used and its usefulness is unquestionable. More complex procedures, such as esophageal, liver or pancreatic resections are, however, more infrequently performed, due to the high grade of skill necessary. As a result, there is less clinical evidence to support its implementation. In the recent years, robot-assisted laparoscopic surgery has been increasingly applied, again with little evidence for comparison with the conventional laparoscopic approach. This review will focus on the complex digestive procedures as well as those whose use in standard practice could be more controversial. Also novel robot-assisted procedures will be updated.

    The phase II randomized controlled trial aimed to compare the outcomes of robot-assisted surgery with those of laparoscopic surgery in the patients with rectal cancer. The feasibility of robot-assisted surgery over laparoscopic surgery for rectal cancer has not been established yet. Between February 21, 2012 and March 11, 2015, patients with rectal cancer (cT1-3NxM0) were enrolled. Patients were randomized 1:1 to either robot-assisted or laparoscopic surgery, and stratified per sex and administration of preoperative chemoradiotherapy. The primary outcome was the quality of total mesorectal excision (TME) specimen. Secondary outcomes were the circumferential and distal resection margins, the number of harvested lymph nodes, morbidity, bowel function recovery, and quality of life. A total of 163 patients were randomly assigned to the robot-assisted (n = 81) and laparoscopic (n = 82) surgery groups, and 139 patients were eligible for the analyses (73 vs 66, respectively). One patient (1.2%) in the robot-assisted group was converted to open surgery. The TME quality did not differ between the robot-assisted and laparoscopic groups (80.3% vs 78.1% complete TME, respectively; 18.2% vs 21.9% nearly complete TME, respectively; P = 0.599). The resection margins, number of harvested lymph nodes, morbidity, and bowel function recovery also were not significantly different. On analyzing quality of life, scores of the European Organization for Research and Treatment of Cancer Quality of Life (EORTC QLQ C30) and EORTC QLQ CR38 were similar in the 2 groups, but in the EORTC QLQ CR 38 questionnaire, sexual function 12 months postoperatively was better in the robot-assisted group than in the laparoscopic group (P = 0.03). Robot-assisted surgery in rectal cancer showed TME quality comparable with that of laparoscopic surgery, and it demonstrated similar postoperative morbidity, bowel function recovery, and quality of life.

    To describe a technique for laparoscopic-assisted removal of cystic calculi in geldings and report outcome. Clinical report. Four geldings with cystic calculi. Laparoscopic-assisted cystotomy and urolith retrieval was performed in 4 anesthetized geldings positioned in dorsal recumbency. With a laparoscope portal located at the umbilicus, the abdomen was insufflated and then the surgical table was tilted (30 degrees head-down position) before an instrumental portal was created parallel and 2-3 cm medial to the left external inguinal ring. Laparoscopic grasping forceps were inserted to grasp the cranial aspect of the bladder and elevate it to the ventral abdominal wall. With the instrumental portal as mid-point, the parainguinal skin incision was longitudinally extended cranial and caudal (approximately 8-10 cm) to accommodate the size of the urolith. The apex of the bladder was exteriorized and sharply incised, the urolith extracted, and after cystotomy closure, the bladder was repositioned. The mini-laparotomy and trocar incisions were closed in layers. There were no intra- or post-operative complications. All horses had minor incisional swelling for 3-4 days. No signs of abdominal or incisional pain were observed. Hematuria and slight stranguria occurred until the 3rd or 4th day. Surgical time (skin incision to skin closure) was 35-40 minutes. On long-term follow-up (up to 12 months) no recurrence of clinical signs associated with cystic calculi occurred. Uroliths (6-8 cm diameter) can be removed by laparoscopic-assisted cystotomy in geldings. Laparoscopic-assisted cystotomy combines the advantages of the parainguinal laparocystotomy with laparoscopic technique for removal of cystic calculi while avoiding their disadvantages.

    With the increasing rates of minimally invasive hysterectomy procedures serving as impetus, the aim of this study was to analyze the 30-day risk profiles associated with total laparoscopic hysterectomy and laparoscopically assisted vaginal hysterectomy (LAVH). The American College of Surgeons National Surgical Quality Improvement Program database was queried for patients who underwent a total laparoscopic hysterectomy or LAVH operation between 2006 and 2010. Patient demographics and 30-day complication rates were calculated. Multivariable regression analyses were used to study the effect of hysterectomy approach on outcomes. A total of 6,190 patients underwent laparoscopic hysterectomy, with 66.3% receiving LAVH and 33.7% receiving a total laparoscopic hysterectomy. The patient cohorts were well-matched. Although total laparoscopic hysterectomy procedures were significantly longer than LAVH operations (2.66 hours compared with 2.20 hours; Plaparoscopic hysterectomy populations (7.05% compared with 6.3% for overall morbidity; 1.3% compared with 1.7% for reoperation). Regression analyses revealed that surgical approach was not a significant predictor of overall postoperative morbidity or reoperation in minimally invasive hysterectomy patients. Additionally, obesity did not demonstrate a significant association with morbidity or reoperation rates; however, operative time was found to be a significant predictor of reoperation (odds ratio 1.23, 95% confidence interval 1.07-1.42). Laparoscopic hysterectomy is well-tolerated with total laparoscopic hysterectomy and LAVH, yielding comparable rates of postoperative morbidity and reoperation. On average, LAVH procedures were 28 minutes faster than total laparoscopic hysterectomy. Additionally, increasing body mass index was not associated with higher rates of morbidity. II.

    Phase III evidence in the shape of a series of randomized controlled trials and meta-analyses has shown that laparoscopic gastrectomy is safe and gives better short-term results with respect to the traditional open technique for early-stage gastric cancer. In fact, in the East laparoscopic gastrectomy has become routine for early-stage gastric cancer. In contrast, the treatment of advanced gastric cancer through a minimally invasive way is still a debated issue, mostly due to worries about its oncological efficacy and the difficulty of carrying out an extended lymphadenectomy and intestinal reconstruction after total gastrectomy laparoscopically. Over the last ten years the introduction of robotic surgery has implied overcoming some intrinsic drawbacks found to be present in the conventional laparoscopic procedure. Robot-assisted gastrectomy with D2 lymphadenectomy has been shown to be safe and feasible for the treatment of gastric cancer patients. But unfortunately, most available studies investigating the robotic gastrectomy for gastric cancer compared to laparoscopic and open technique are so far retrospective and there have not been phase III trials. In the present review we looked at scientific evidence available today regarding the new high-tech surgical robotic approach, and we attempted to bring to light the real advantages of robot-assisted gastrectomy compared to the traditional laparoscopic and open technique for the treatment of gastric cancer.

    Introduction Closed reduction of distal radius fractures (CRDRF) is a commonly performed emergency department (ED) procedure. The use of point-of-care ultrasound (PoCUS) to diagnose fractures and guide reduction has previously been described. The primary objective of this study was to determine if the addition of PoCUS to CRDRF changed the perception of successful initial reduction. This was measured by the rate of further reduction attempts based on PoCUS following the initial clinical determination of achievement of best possible reduction. Methods  We performed a multicenter prospective cohort study, using a convenience sample of adult ED patients presenting with a distal radius fracture to five Canadian EDs. All study physicians underwent standardized PoCUS training for fractures. Standard clinically-guided best possible fracture reduction was initially performed. PoCUS was then used to assess the reduction adequacy. Repeat reduction was performed if deemed indicated. A post-reduction radiograph was then performed. Clinician impression of reduction adequacy was scored on a 5 point Likert scale following the initial clinically-guided reduction and following each PoCUS scan and the post-reduction radiograph. Results  There were 131 patients with 132 distal radius fractures. Twelve cases were excluded prior to analysis. There was no significant difference in the assessment of the initial reduction status by PoCUS as compared to the clinical exam (mean score: 3.8 vs. 3.9; p = 0.370; OR 0.89; 95% CI 0.46 to 1.72; p = 0.87). Significantly fewer cases fell into the uncertain category with PoCUS than with clinical assessment (2 vs 12; p = 0.008). Repeat reduction was performed in 49 patients (41.2%). Repeat reduction led to a significant improvement (p < 0.001) in the PoCUS determined adequacy of reduction (mean score: 4.3 vs 3.1; p < 0.001). In this group, the odds ratio for adequate vs. uncertain or inadequate reduction assessment using PoCUS was 12.5 (95% CI 3

    Pancreatic neuroendocrine tumors (PNETs) account for 1-2% of all pancreatic neoplasms. Nonfunctioning PNETs (NF-PNETs) account for 60-90% of all PNETs. Laparoscopic distal pancreatectomy (LDP) is becoming the treatment of choice for benign lesions in the body and tail of the pancreas. However, LDP has not yet been widely accepted as the gold standard for NF-PNETs. The purpose of this study is to evaluate the clinical and oncologic outcomes after laparoscopic versus open distal pancreatectomy (ODP) for NF-PNETs. Between April 1995 and September 2016, 94 patients with NF-PNETs underwent open or laparoscopic distal pancreatectomy at Samsung Medical Center. Patients were divided into two groups: those who underwent LDP and those who underwent ODP. Both groups were compared in terms of clinical and oncologic variables. LDP patients had a significantly shorter hospital stay compared with ODP patients, amounting to a mean difference of 2 days (p < 0.001). Overall complication rates did not differ significantly between the ODP and LDP groups (p = 0.379). The 3-year overall survival rates in the ODP and LDP groups were 93.7 and 100%, respectively (p = 0.069). In this study, LDP for NF-PNETs had similar oncologic outcomes compared with ODP. In addition, LDP was associated with a shorter hospital stay compared with ODP. Therefore, LDP is a safe and effective procedure for patients with NF-PNETs. A multicenter study and a randomized controlled trial are needed to better assess the clinical and oncologic outcomes.

    Full Text Available A 34-year-old woman presented with pain during menstruation and was diagnosed with endometriosis of the lower rectum. Despite treatment with an LH-RH agonist, she was unable to become pregnant and surgical removal of her endometriosis was recommended. Preoperative magnetic resonance imaging revealed endometriosis localized between the neck of the uterus and rectum with indentation and scuffing. Laparoscopically assisted low anterior resection was performed. Exfoliation was started from the right side of the rectum to the presacral and retrorectal space, and the rectococcygeus ligament was transected. Exfoliation of the retrorectal space was continued to the levator ani muscle and mobilization of the right side of the rectum was performed. In front of the rectum, exfoliation was started posterior to the wall of the vagina, but layers became unclear near the tumor as the tissue was solid in this region. The left hypogastric nerve close to the tumor was inflamed and it was cut. The layer of the exfoliation was connected to the right side of the rectum, the tumor was isolated from the vagina, and the lower rectum was transected at a point 1 cm distal to the tumor with a 60-mm linear stapler. Reconstruction with a 31-mm circular stapler was performed using the double stapling technique. Operative time was 520 min with a blood loss of 320 ml. On the 9th post operative day, a rectovaginal fistula occurred, and ileostomy was performed. The patient was discharged from the hospital on the 25th postoperative day, and 4 months later, stoma closure was performed.

    Nephron-sparing surgery has been proven to positively impact the postoperative quality of life for the treatment of small renal tumors, possibly leading to functional improvements. Laparoscopic partial nephrectomy is still one of the most demanding procedures in urological surgery. Laparoscopic partial nephrectomy sometimes results in extended warm ischemic time and severe complications, such as open conversion, postoperative hemorrhage and urine leakage. Robot-assisted partial nephrectomy exploits the advantages offered by the da Vinci Surgical System to laparoscopic partial nephrectomy, equipped with 3-D vision and a better degree in the freedom of surgical instruments. The introduction of the da Vinci Surgical System made nephron-sparing surgery, specifically robot-assisted partial nephrectomy, safe with promising results, leading to the shortening of warm ischemic time and a reduction in perioperative complications. Even for complex and challenging tumors, robotic assistance is expected to provide the benefit of minimally-invasive surgery with safe and satisfactory renal function. Warm ischemic time is the modifiable factor during robot-assisted partial nephrectomy to affect postoperative kidney function. We analyzed the predictive factors for extended warm ischemic time from our robot-assisted partial nephrectomy series. The surface area of the tumor attached to the kidney parenchyma was shown to significantly affect the extended warm ischemic time during robot-assisted partial nephrectomy. In cases with tumor-attached surface area more than 15 cm(2) , we should consider switching robot-assisted partial nephrectomy to open partial nephrectomy under cold ischemia if it is imperative. In Japan, a nationwide prospective study has been carried out to show the superiority of robot-assisted partial nephrectomy to laparoscopic partial nephrectomy in improving warm ischemic time and complications. By facilitating robotic technology, robot-assisted partial nephrectomy

    The aim of the present review is to summarize recent developments in the field of urologic robotic surgery. A nonsystematic literature review was performed to retrieve publications related to robotic surgery in urology and evidence-based critical analysis was conducted by focusing on the literature of the past 5 years. The use of the da Vinci Surgical System, a robotic surgical system, has been implemented for the entire spectrum of extirpative and reconstructive laparoscopic kidney procedures. The robotic approach can be applied for a range of adrenal indications as well as for ureteral diseases, including benign and malignant conditions affecting the proximal, mid, and distal ureter. Current evidence suggests that robotic prostatectomy is associated with less blood loss compared with the open surgery. Besides prostate cancer, robotics has been used for simple prostatectomy in patients with symptomatic benign prostatic hyperplasia. Recent studies suggest that minimally invasive radical cystectomy provides encouraging oncologic outcomes mirroring those reported for open surgery. In recent years, the evolution of robotic surgery has enabled urologic surgeons to perform urinary diversions intracorporeally. Robotic vasectomy reversal and several other robotic andrological applications are being explored. In summary, robotic-assisted surgery is an emerging and safe technology for most urologic operations. The acceptance of robotic prostatectomy during the past decade has paved the way for urologists to explore the entire spectrum of extirpative and reconstructive urologic procedures. Cost remains a significant issue that could be solved by wider dissemination of the technology. Copyright © 2014 American Society for Reproductive Medicine. Published by Elsevier Inc.

    "Laparoscopic assisted appendicectomy" refers to visualization of abdominal cavity, identification of appendix, drawing the appendix out through the port wound and appendicectomy. The objective of this study is to evaluate the outcome of the procedure of laparoscopic assisted appendicectomy. In this prospective study patients with appendicitis were randomly selected for laparoscopic assisted appendicectomy from August 2007 to February 2009 in the Department of Surgery, Modernized District Hospital, Joypurhat, Bangladesh. Out of 73 patients Laparoscopic assisted appendicectomy was performed successfully in 95.89% cases and conversion rate was 4.11%. Male to female ratio was almost 1:2 with mean±SD age 18.62±9.16 years. The wound infection rate was 8.2% and urinary retention 2.7%. Early postoperative feeding was started within 24 hours in 86.3% cases and mean duration of hospital stay was 2 days in 76.71% patients. More than 82% returned to their home and started social activities within 5 days. Duration of surgery was almost similar in emergency and interval appendicectomy group (19.35±10.13 vs. 23.66±9.43) minutes. Postoperative morbidity in emergency appendicectomy group showed significantly higher morbidity than interval appendicectomy group (p=0.003). This study indicates that the laparoscopic assisted appendicectomy is feasible for the majority of the patients with appendicitis in both emergency and interval settings. It reduces the operative time, shortens hospital stay and helps in early resumption of normal activities with good cosmetic outcome and patients' satisfaction.

    Surgery using a robotic platform is expanding rapidly today, with a notable surge since its authorization on the international medical market by the US Food and Drug Administration in 2000. The first hepatectomy by a robotic approach was reported in 2002, 10 years after the first laparoscopic hepatectomy. Yet, in hepatic surgery, series are scarce and the lack of relevant data in the literature is an obstacle to the development of robot-assisted laparoscopic hepatectomy (RALH). Based on a review of the literature, this update focuses on current indications, short-term and oncologic outcomes following RALH.

    To present the technique and outcomes of single trocar laparoscopic-assisted colostomy in newborns. A rectangular skin flap was developed at the left subcostal area and detached from the fascia. Then the fascia and peritoneum were opened longitudinally around 11 mm, and then a 10-mm trocar was inserted into the abdominal cavity. The 10-mm operating laparoscope (Stema, Germany) was inserted through the trocar. The left transverse colon was inspected, grasped and brought outside the abdominal cavity with a Babcock grasper. The skin flap was inserted through a window created at the colon mesentery and secured to the opposite side to elevate the colon. A loop colostomy was performed. From August 2009 to December 2011, single trocar laparoscopic-assisted colostomy was performed for 39 newborns with anorectal malformations, including 26 boys and 13 girls. Mean operative time was 24 ± 4 min (range 20-30 min). There were no perioperative deaths or complications. Mean postoperative stay was 3 ± 0.6 days. Single trocar laparoscopic-assisted colostomy is a feasible and safe procedure in newborns.

    Purpose To report the first case of robotic-assisted laparoscopic management of a symptomatic caliceal diverticular calculus and review the literature on laparoscopic treatment for this condition. Case report A 33-year-old obese woman with a 2×1 cm calculus within an anterior caliceal diverticulum located in the middle pole of the left kidney was referred to our service. She had already undergone two flexible ureterorenoscopies without success. We considered that a percutaneous approach would be very challenging due to stone location, thus we elected to perform a robotic-assisted laparoscopic procedure for stone removal and diverticulum fulguration. The procedure was uneventfully performed with no intraoperative or postoperative complications. The patient was discharged from the hospital on the second postoperative day and after 1.5 years of follow-up she is asymptomatic with no recurrence. Conclusions The robotic-assisted laparoscopic approach to caliceal diverticular calculi is feasible and safe, providing one more option for treatment of stones in challenging locations.

    2011-01-01

    Full Text Available A successful laparoscopic-assisted cryptorchidectomy is reported in a novel species, the reindeer (Rangifer tarandus. The procedure was performed in an 8-year-old adult positioned in dorsolateral oblique recumbency, with an open approach midline subumbilical placement of the primary 10 mm optical port and carbon dioxide insufflation at 12 mmHg. Three 5 mm instrument ports were inserted under visualization in the left caudal abdomen as the retained testicle was localized to the internal inguinal ring. A 5 mm flexible organ retractor was used to assist in localizing the retained testicle. This procedure provided a less invasive alternative to open laparotomy. The authors are unaware of any published reports of laparoscopy in reindeer, or of laparoscopic assisted cryptorchidectomy in deer species.

    Since a patient's obesity can affect the mortality and morbidity of the surgery, less drastic surgeries may have a major benefit for obese individuals. This study evaluated the feasibility of performing a totally laparoscopic distal gastrectomy, with intracorporeal anastomosis, in obese patients suffering from gastric cancer. This was a retrospective analysis of the 138 patients, who underwent a totally laparoscopic distal gastrectomy from April 2005 to March 2009, at the National Kyushu Cancer Center. The body mass index of 20 patients was ≥25, and in 118 patients, it was obese patients than in the non-obese patients. The intraoperative blood loss, duration of surgery, post-operative complication rate, post-operative hospital stay, and a number of retrieved lymph nodes were not significantly different between the two groups. Intracorporeal anastomosis seemed to have a benefit for obese individuals. Totally laparoscopic gastrectomy is, therefore, considered to be a safe and an effective modality for obese patients.

    Robotic surgery has been developed with the aim of improving surgical quality and overcoming the limitations of conventional laparoscopy in the performance of complex mini-invasive procedures. The present study was designed to compare robotic and laparoscopic distal gastrectomy in the treatment of gastric cancer. Between June 2008 and September 2015, 41 laparoscopic and 30 robotic distal gastrectomies were performed by a single surgeon at the same institution. Clinicopathological characteristics of the patients, surgical performance, postoperative morbidity/mortality and pathologic data were prospectively collected and compared between the laparoscopic and robotic groups by the Chi-square test and the Mann-Whitney test, as indicated. There were no significant differences in patient characteristics between the two groups. Mean tumor size was larger in the laparoscopic than in the robotic patients (5.3 ± 0.5 cm and 3.0 ± 0.4 cm, respectively; P = 0.02). However, tumor stage distribution was similar between the two groups. The mean number of dissected lymph nodes was higher in the robotic than in the laparoscopic patients (39.1 ± 3.7 and 30.5 ± 2.0, respectively; P = 0.02). The mean operative time was 262.6 ± 8.6 min in the laparoscopic group and 312.6 ± 15.7 min in the robotic group (P < 0.001). The incidences of surgery-related and surgery-unrelated complications were similar in the laparoscopic and in the robotic patients. There were no significant differences in short-term clinical outcomes between the two groups. Within the limitation of a small-sized, non-randomized analysis, our study confirms that robotic distal gastrectomy is a feasible and safe surgical procedure. When compared with conventional laparoscopy, robotic surgery shows evident benefits in the performance of lymphadenectomy with a higher number of retrieved and examined lymph nodes.

    A 44-year-old woman underwent surgical resection and received preoperative and postoperative chemotherapy for conventional osteosarcoma in the right fibular head. Three years later, follow-up PET-CT revealed accumulation ofFDG in the tail ofthe pancreas. Contrast-enhanced computed tomography showed a 13mm well-circumscribed hypovascular tumor. EUS showed a heterogeneous solid tumor, which was diagnosed as metastasis ofosteosarcoma to the pancreas. Laparoscopic spleen preserving distal pancreatectomy(LAP-SPDP)was performed. Pathologically, the tumor was diagnosed as metastasis ofconventional osteosarcoma to the pancreas. Cells from pancreas islet tissue were detected in the tumor, suggesting invasion ofthe tumor into the pancreatic body and surrounding adipose tissue. Although postoperative chemotherapy was administered, lung metastasis was detected 1.1 years after surgery. Laparoscopic partial resection of the lung metastasis was performed, and the patient is still alive. Metastasis ofosteosarcoma to the pancreas is rare, and there is no report oflaparoscopic approach as a treatment. Herein, we report a case with several references.

    Laparoscopic surgery through a single incision is gaining popularity with different stakeholders. The advantages of improved cosmetics, decreased postoperative pain and blood loss continue to attract patients from different surgical fields. Multidisciplinary approach to different surgical entities through a single incision has just been introduced. We report the first case of a synchronous single-port access (SPA) laparoscopic right hemicolectomy and laparoscopic-assisted vaginal hysterectomy with bilateral salpingo-oophorectomy through a single incision above the umbilicus in a 48-year-old female with ascending colon mass and uterine mass with good postoperative outcomes. SPA laparoscopic surgery is feasible for multidisciplinary approach in resectable tumors. PMID:28096321

    Full Text Available Multiple shunt failure is a challenge in pediatric neurosurgery practice and one of the most feared complications of hydrocephalus. Objective: To demonstrate that laparoscopic procedures for distal ventriculoperitoneal shunt failure may be an effective option for patients who underwent multiple revisions due to repetitive manipulation of the peritoneal cavity, abdominal pseudocyst, peritonitis or other situations leading to a “non reliable” peritoneum. Method: From March 2012 to February 2013, the authors reviewed retrospectively the charts of six patients born and followed up at our institution, which presented with previous intra-peritoneal complications and underwent ventriculoperitoneal shunt revision assisted by video laparoscopy. Results: After a mean follow-up period of nine months, all patients are well and no further shunt failure was identified so far. Conclusion: Laparoscopy assisted shunt revision in children may be, in selected cases, an effective option for patients with multiple peritoneal complications due to ventriculo-peritoneal shunting.

    Full Text Available OBJECTIVE: Report the authors’ initial experience with hand-assisted laparoscopic nephrectomy technique in renal donors for transplantation. MATERIALS AND METHODS: Twenty-seven donors submitted to hand-assisted laparoscopic nephrectomy were retrospectively analyzed from February 2001 to June 2002. Technical aspects of the donor surgery, results, and complications, are discussed, as well as recipient’s complications and outcomes. RESULTS: Among 27 hand-assisted laparoscopic nephrectomies, left kidney was withdrew in 18 donors (66.6%, and right kidney in 9 (33.3%. The operative time ranged from 55 to 210 minutes (mean 132.7 ± 37.6 min, and the time of hot ischemia ranged from 2 to 11 minutes (mean 4.7 ± 2.5 min, with an estimated mean blood loss during the intraoperative period of 133.3 mL. Conversion to open surgery was necessary for 1 (3.7% patient due to vascular lesion. In graft evaluation, immediate diuresis was observed in 26 (96.3% cases, and mean serum creatinine in PO day 7 was 1.5 ± 1.1 mg/dL. Renal vein thrombosis occurred in 1 (3.7% patient requiring graft removal. Lymphocele was observed in 3 recipients (11.1%, and urinary leakage due to ureteral necrosis in 1 case (3.7%. CONCLUSION: Hand-assisted laparoscopic nephrectomy in living donors is a safe procedure and an effective alternative to open nephrectomy. In this series, the procedure presented low morbidity after surgery providing to the recipient a good morphological and functional quality of the graft.

    2006-01-01

    AIM: To design a hand-assisted laparoscopic approach in an attempt to provide an option for laparoscopic resection of abdominal large viscera.METHODS: A 5-6 cm incision (for HandPort) and 2 trocars were employed. The main vessel of the target organ was taken as a "core", and all tissues around the core were taken as peripheral structures. The peripheral structures were dissected first, and the core vessels were treated last. Twenty-six patients underwent laparoscopic deroofing of the hepatic huge cysts, resection of the segments lying at the outer edge of the liver (segments 2 to 6), splenectomy, hemicolectomy, ileocecectomy and subtotal gastrectomy with HandPort device, harmonic scalpel, or Ligasure.RESULTS: The duration of the procedure was within 2 hours. Blood loss amounted to 8-120 mL. The conversion rate was 3.8% (1/26). All patients had uneventful postoperative courses with less pain, earlier oral intake,and faster recovery, compared with conventional surgery.CONCLUSION: This method combines the advantages of both open and laparoscopic techniques, achieving better hemostasis effect, shortening the operative time,and is beneficial to the patients.

    To compare the effects of obesity on laparoscopy-assisted distal gastrectomy (LADG) and open distal gastrectomy (ODG). A retrospective study was conducted on 249 patients, who underwent LADG and 224 patients who underwent ODG. The regression coefficient of the primary regression equation between operative time and body mass index (BMI) for LADG was greater than ODG; and between blood loss and BMI for LADG was almost the same as ODG. In overweight patients (BMI ≥25), no significant difference was seen between LADG and ODG regarding postoperative complications, and the benefits of the less-invasive nature of LADG were also seen in some parameters. Obesity-associated difficulties are more while performing LADG than during ODG; however, the influence of obesity on LADG decreases with surgical experience. Moreover, even in overweight patients, the benefits of the less-invasive nature of LADG still remain, but the degree of the benefits is smaller than that in nonobese patients.

    Despite the increasing prevalence of obesity and gastric diseases, the impact of obesity on short- and long-term outcomes of laparoscopic distal gastrectomy for gastric cancer still remains unclear. Sixty-one consecutive obese patients with body mass index (BMI)≥30 kg/m(2), who underwent laparoscopic distal gastrectomy, were compared with 76 non-obese patients with BMIObesity was associated with a longer operative time and a greater estimated blood loss. The rate of conversion to open distal gastrectomy was similar between the two groups. There were no 30-day postoperative deaths in either group. There was no significant difference in the overall number or severity of 30-day postoperative complications between the two groups. Regarding long-term survival outcomes, there was no statistical difference in overall (OS) or disease-free survival (DFS) between the two groups. Multivariate analysis showed that BMI did not influence prognosis. Laparoscopic distal gastrectomy appears to be a safe and reasonable option for selected obese patients with gastric cancer and results in short- and long-term outcomes similar to those in non-obese patients.

    Abstract Objective: To describe the management of the distal ureter during radical nephroureterectomy with the transvesical laparoendoscopic single-site surgery (T-LESS) approach. Methods: Between January 2010 and October 2013, five patients underwent laparoscopic radical nephroureterectomy for upper urinary tract carcinoma (UTUC) with the T-LESS approach. Patients were placed in the supine position. A 2.5-cm skin incision was made in the line between the pubis and the umbilicus. The bladder was identified and a multiport was inserted into the bladder. The patients were repositioned to a lateral decubitus position; pneumovesicum was established and the ureteral openings were identified. We marked the bladder cuff with electrocautery all the way through to the extravesical fat. The bladder defect was sealed with sutures. After checking for any leak or bleeding, the multiport was removed and the bladder was closed. At this point, we continued with nephrectomy by standard laparoscopy or LESS. A 18F Foley catheter was placed into the bladder. Results: The mean age was 70 years (range 58-81 years), the mean operative time was 198 minutes (range 115-390 minutes), the mean time for the management of the distal ureter was 35 minutes (range 27-45 minutes), the mean estimated blood loss was 234 mL (range 60-850 mL), and the mean hospital stay was 3.8 days (range 2-8 days). In all patients the bladder cuff was free of disease. Conclusion: The transvesical laparoendoscopic single-site approach to the distal ureter for UTUC appears safe and reproducible, with faster closure of the bladder defect and improved cosmesis.

    Robot-assisted laparoscopic surgery (RALS) has been proven to be safe and effective for various urological procedures in children, including pyeloplasty, orchiopexy, nephrectomy, and bladder augmentation. The robot system enables delicate and precise movements, which are ideal for the types of reconstructive surgeries that children with urological issues often require, overcoming many of the impediments associated with the conventional laparoscopic approach. RALS helps the relative novice to perform fine surgical techniques and is thought to reduce the learning curve associated with some surgical techniques, such as intracorporeal suturing, owing to the improved freedom of movement of the surgical instruments, the ergonomic positioning of the surgeon, and the 3D vision provided by the robotic system. Given the favourable safety profile and associated benefits of the robot system, including reductions in mean postoperative hospital stay compared with conventional procedures, RALS is becoming more widely adopted by paediatric urologists.

    Laparoscopic distal gastrectomy for gastric cancer has been firmly established in recent decades but still is a difficult procedure, especially for obese patients, as with open surgery. This study aimed to evaluate the perioperative outcome of total laparoscopic distal gastrectomy (TLDG) for early gastric cancer patients with a body mass index (BMI) exceeding 25 kg/m(2) and to consider countermeasures to this. Perioperative outcomes were compared between 42 patients with a BMI exceeding 25 kg/m(2) [overweight or obese group (OWG)] and 174 patients with a BMI lower than 25 kg/m(2) [normal or underweight group (NWG)] who underwent TLDG between September 2010 and December 2012. The BMI was 26.0 ± 1.4 kg/m(2) in the OWG group and 22.0 ± 2.1 kg/m(2) in the NWG group (P obese patients, TLDG was managed safely. The procedure was considered to be difficult but sufficiently feasible.

    ABSTRACT Introduction and objective Retroperitoneal lymph node dissection (RPLND) is indicated for patients with non-seminomatous germ cell tumor (NSGCT) with residual disease after chemotherapy. Although the gold standard approach is still the open surgery, few cases of robot-assisted laparoscopic RPLND have been described. Herein, we aim to present the surgical technique for robot-assisted laparoscopic RPLND. Patient and method A 30 year-old asymptomatic man presented with left testicular swelling for 2 months. Physical examination revealed an enlarged and hard left testis. Alpha-fetoprotein (>1000ng/mL) and beta-HCG (>24.000U/L) were increased. Beta-HCG increased to >112.000U/L in less than one month. The patient underwent a left orchiectomy. Pathological examination showed a mixed NSGCT (50% embryonal carcinoma; 30% teratoma; 10% yolk sac; 10% choriocarcinoma). Computed tomography scan revealed a large tumor mass close to the left renal hilum (10x4x4cm) and others enlarged paracaval and paraortic lymph nodes (T2N3M1S3-stage III). Patient was submitted to 4 cycles of BEP with satisfactory response. Residual mass was suggestive of teratoma. Based on these findings, he was submitted to a robot-assisted RPLND. Results RPLND was uneventfully performed. Operative time was 3.5 hours. Blood loss was minimal, and there were no intra- or postoperative complications. The patient was discharged from hospital in the 1st postoperative day. Pathological examination showed a pure teratoma. After 6 months of follow-up, patient is asymptomatic with an alpha-fetoprotein of 2.9ng/mL and an undetectable beta-HCG. Conclusion Robot-assisted laparoscopic RPLND is a feasible procedure with acceptable morbidity even for post chemotherapy patients when performed by an experienced surgeon.

    Background. Although Billroth II (BII) reconstruction is simpler and faster than Billroth I or Roux-en-Y (RY) reconstruction in patients undergoing totally laparoscopic distal gastrectomy (TLDG), BII reconstruction is associated with several complications, including more severe bile reflux. BII Braun anastomosis may be a better alternative to RY reconstruction. Methods. This retrospective study included 56 consecutive patients who underwent TLDG for gastric cancer, followed by BII Braun or RY...

    To assess differences between laparoscopic hysterectomy performed with or without robot-assistance, we performed metaanalyses of 5 key indices strongly associated with societal and hospital costs, patient safety, and intervention quality. The 5 indexes included estimated blood loss (EBL), operative time, number of conversions to laparotomy, hospital length of stay (LOS), and number of postoperative complications. A search of PubMed, Medline, Embase, and Science citation index online databases yielded a total of 605 studies. After a systematic review, we proceeded with meta-analysis of 14 articles for EBL, with a summary effect of -0.61 (95% confidence interval [CI], -42.42 to 46.20); 20 for operative time, with a summary effect of 0.66 (95% CI, -15.72 to 17.04); 17 for LOS, with a summary effect of -0.43 (95% CI, -0.68 to -0.17); 15 for conversion to laparotomy (odds ratio, 0.50; 95% CI, 0.31 to 0.79 with a random model); and 14 for postoperative complications (odds ratio, 0.69; 95% CI, 0.43 to 1.09 with a random model). In conclusion, compared with traditional laparoscopic hysterectomy, robot-assisted laparoscopic hysterectomy was associated with shorter LOS and fewer postoperative complications and conversions to laparotomy; there were no differences in EBL and operative time. These results confirm that robot-assisted laparoscopy has less deletorious effect on hospital, society, and patient stress and leads to better intervention quality. Copyright © 2011 AAGL.

    Laparoscopic resection of rectal cancer or gastric cancer has been advocated for the benefits of a reduced morbidity,a shorter treatment time,and similar outcomes.However,simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy for synchronous carcinoma of rectum and stomach are rarely documented in literature.Endoscopic examination revealed a synchronous carcinoma of rectum and stomach in a 55-year-old male patient with rectal bleeding and epigastric discomfort.He underwent a simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy with regional lymph nodes dissected.The operation time was 270min and the estimated blood loss was 120mL.The patient required parenteral analgesia for less than 24h.Flatus was passed on postoperative day 3,and a solid diet was resumed on postoperative day 7.He was discharged on postoperative day 13.With the advances in laparoscopic technology and experience,simultaneous resection is an attractive alternative to a synchronous gastrointestinal cancer.

    This study assessed the patient-specific risk for major postoperative morbidity in a series of 100 laparoscopic distal pancreatectomies (LDP). A previously established complication risk score (CRS), identifying body mass index (BMI), estimated blood loss (EBL), and pancreatic specimen length as determinants of postoperative morbidity were examined against the observed outcomes. In addition, multivariate analyses were performed to investigate risk factors specific to our study population. The postoperative morbidity rate was 49 %, major complication accounted for 12 %, and clinically relevant pancreatic fistulae (PF) were 13 %. The incidence of any complications, major complications, any PF, and clinically relevant PF did not vary appreciably when the CRS increased. The multivariate analysis indicated that male sex and an EBL ≥150 mL were independent predictors of major morbidity and clinically relevant PF. In conclusion, the previously published CRS based on pre- and intraoperative factors was not able to predict the postoperative risk in our population. This is probably because risk scores may not be able to adjust for the case-mix (heterogeneity in baseline patient characteristics). According to our data, men and patients with EBL ≥150 mL are more likely to develop major postoperative complications after LDP.

    Full Text Available We report a case of primary clear cell hepatocellular carcinoma of the liver (PCCCL for which we performed hand-assisted laparoscopic hepatectomy. A 71-year-old female with hepatitis C infection and diabetes mellitus was admitted to our department for a hepatic tumor with gallstone. Abdominal computed tomography revealed a tumor 25 mm in diameter on the surface in segment 5 of the liver. The imaging results suggested small hepatocellular carcinoma located on the surface in segment 5 of the liver, and we performed laparoscopic surgery aiming at a minimally invasive procedure. We performed laparoscopic cholecystectomy and hand-assisted laparoscopic hepatectomy. Histopathological findings showed moderately differentiated hepatocellular carcinoma, and as the proportion of clear cells was 75%, the tumor was diagnosed as PCCCL. This is the first report of hand-assisted laparoscopic hepatectomy for PCCCL. Laparoscopic hepatectomy is a useful minimally invasive surgical procedure when the tumor is located on the surface of the liver.

    The aim of the study is to investigate the outcomes of the da Vinci robot-assisted laparoscopic hernia repair of small-sized ventral hernias with circumferential suturing of the mesh compared to the traditional laparoscopic repair with trans-fascial suturing. A retrospective review was conducted of all robot-assisted umbilical, epigastric and incisional hernia repairs performed at our institution between 2013 and 2015 compared to laparoscopic umbilical or epigastric hernia repairs. Patient characteristics, operative details and postoperative complications were collected and analyzed using univariate analysis. Three primary minimally invasive fellowship trained surgeons performed all of the procedures included in the analysis. 72 patients were identified during the study period. 39 patients underwent robot- assisted repair (21 umbilical, 14 epigastric, 4 incisional), and 33 patients laparoscopic repair (27 umbilical, 6 epigastric). Seven had recurrent hernias (robot: 4, laparoscopic: 3). There were no significant differences in preoperative characteristics between the two groups. Average operative time was 156 min for robot-assisted repair and 65 min for laparoscopic repair (p robot group [3.07 cm (1-9 cm)] than that for the laparoscopic group [2.02 cm (0.5-5 cm)] (p robot-assisted technique versus the standard laparoscopic repair.

    Full Text Available PURPOSE: To compare hand-assisted laparoscopic donor nephrectomy and pure laparoscopic live donor nephrectomy techniques in live donor nephrectomy. METHODS: In this retrospective study, we included all patients submitted to hand-assisted laparoscopic donor nephrectomy and pure laparoscopic live donor nephrectomy between May 2002 and December 2007. The operative data and post-operative courses were reviewed. Information was collected on the operative time, warm ischemia time, estimated blood loss, intra-operative complications, time to first oral intake, length of hospital stay, and post-operative complications. The data were analyzed using Student's t -tests and Fisher exact tests as appropriate, with statistical significance defined as p < 0.05. RESULTS: The means of the operative duration, warm ischemia time and intra-operative bleeding were 83 min, 3.6 min and 130.9 cc, respectively, for hand-assisted laparoscopic donor nephrectomy, and 78.4 min, 2.5 min and 98.9 cc, respectively, for pure laparoscopic live donor nephrectomy (p=0.29, p<0.0001 and p=0.08, respectively. Intra-operative complications occurred in 6% of patients submitted to hand-assisted laparoscopic donor nephrectomy and in 4.5% of those submitted to pure laparoscopic live donor nephrectomy (p=0.68. Only one patient from each group required conversion to open surgery; one person receiving hand-assisted laparoscopic donor nephrectomy had bleeding and one person receiving pure laparoscopic live donor nephrectomy had low carbon dioxide levels during the warm ischemia period. Compared with patients receiving hand-assisted laparoscopic donor nephrectomy, patients submitted to pure laparoscopic live donor nephrectomy were able to take their first meal earlier (12.5 vs. 9.2 hours, p=0.046, were discharged home sooner (2.8 vs. 1.4 days, p<0.0001 and had fewer post-operative complications (7.5% vs. 0.6%, p=0.04. CONCLUSIONS: Pure laparoscopic live donor nephrectomy had some advantages

    Robot-assisted laparoscopic radical prostatectomy (RALRP) using the da Vinci surgical system is now in widespread use in many countries where economic conditions allow the installation of this expensive technology.Controversy has surrounded the procedure since it was first performed in 2000,with many critics highlighting the lack of evidence to support its use.However,despite the lack of level I evidence,many large studies of patients have confirmed that the procedure is feasible and safe,with low morbidity.Available longer-term oncological data seem to show that outcomes from the robotic approach at least match those of traditional open radical prostatectomy.Functional outcomes also seem satisfactory,although randomized controlled trials are lacking.This paper reviews the current status of RALRP with respect to perioperative data and complications and oncologic and functional outcomes.

    Stomach traction done to expose the pancreas is still a problem in laparoscopic left pancreatic resections. We developed a simple hanging maneuver to retract the stomach rapidly and effectively. After dividing the gastrocolic ligament, the stomach was encircled with a tape, turned along its horizontal axis and pulled with an epigastric trocar, which was later removed. This technique was used in all patients who underwent laparoscopic left pancreatic resections including 165 distal pancreatectomies (DP), 35 central pancreatectomies (CP) and 18 enucleations (En). Demographics, surgical and postoperative outcome data were recorded. There were no mortalities. The mean operative time for DP, CP and En were 174, 191 and 104 min, respectively. The transfusion (0-4%) and conversion (0-3%) rates were low for all procedures. Morbidity was mainly represented by pancreatic fistula and grades (B + C) for DP, CP and En were observed in 26, 22 and 17%, respectively. No complication related to hanging of the stomach, like gastric perforation, was observed. Re-intervention and the mean hospital stay for DP, CP and En were observed in 5, 11 and 0% and were 16, 22 and 12, respectively. The readmission rate was low (0-9%). Hanging maneuver of the stomach is a simple procedure to rapidly, safely and effectively retract the stomach during left laparoscopic pancreatic resections. © 2016 S. Karger AG, Basel.

    Background With the availability of infliximab, nowadays recurrent Crohn's disease, defined as disease refractory to immunomodulatory agents that has been treated with steroids, is generally treated with infliximab. Infliximab is an effective but expensive treatment and once started it is unclear when therapy can be discontinued. Surgical resection has been the golden standard in recurrent Crohn's disease. Laparoscopic ileocolic resection proved to be safe and is characterized by a quick symptom reduction. The objective of this study is to compare infliximab treatment with laparoscopic ileocolic resection in patients with recurrent Crohn's disease of the distal ileum with respect to quality of life and costs. Methods/design The study is designed as a multicenter randomized clinical trial including patients with Crohn's disease located in the terminal ileum that require infliximab treatment following recent consensus statements on inflammatory bowel disease treatment: moderate to severe disease activity in patients that fail to respond to steroid therapy or immunomodulatory therapy. Patients will be randomized to receive either infliximab or undergo a laparoscopic ileocolic resection. Primary outcomes are quality of life and costs. Secondary outcomes are hospital stay, early and late morbidity, sick leave and surgical recurrence. In order to detect an effect size of 0.5 on the Inflammatory Bowel Disease Questionnaire at a 5% two sided significance level with a power of 80%, a sample size of 65 patients per treatment group can be calculated. An economic evaluation will be performed by assessing the marginal direct medical, non-medical and time costs and the costs per Quality Adjusted Life Year (QALY) will be calculated. For both treatment strategies a cost-utility ratio will be calculated. Patients will be included from December 2007.

    Full Text Available Abstract Background Laparoscopic live donor nephrectomy has become the preferred method of donor nephrectomy at many transplant centers. The laparoscopic stapling device is commonly used for division of the renal vessels. Malfunction of the stapling device can occur, and is often due to interference from previously placed clips. We report our experience with a clipless technique in which no vascular clips are placed on tributaries of the renal vein at or near the renal hilum in order to avoid laparoscopic stapling device misfires. Methods From December 20, 2002 to April 12, 2005, 50 patients underwent hand-assisted laparoscopic left donor nephrectomy (LDN at our institution. Clipless management of the renal vein tributaries was used in all patients, and these vessels were divided using either a laparoscopic stapling device or the LigaSureTM device (Valleylab, Boulder, CO. The medical and operative records of the donors and recipients were reviewed to evaluate patient outcomes. Results The mean follow-up time was 14 months. Of the 50 LDN procedures, there were no laparoscopic stapling device malfunctions and no vascular complications. All renal allografts were functioning at the time of follow-up. Conclusion Laparoscopic stapling device failure due to deployment across previously placed surgical clips during laparoscopic live donor nephrectomy can be prevented by not placing clips on the tributaries of the renal vein. In our series, there were no vascular complications and no device misfires. We believe this clipless technique improves the safety of laparoscopic donor nephrectomy.

    2015-01-01

    Full Text Available Objective. To examine success of robot-assisted laparoscopic myomectomy (RALM measured by sustained symptom relief and fertility. Methods. This is a retrospective survey of 426 women who underwent RALM for fibroids, symptom relief, or infertility at three practice sites across the US. We examined rates of symptom recurrence and pregnancy and factors associated with these outcomes. Results. Overall, 70% of women reported being symptom-free, with 62.9% free of symptoms after three years. At >3 years, 66.7% of women who underwent surgery to treat infertility and 80% who were also symptom-free reported achieving pregnancy. Factors independently associated with symptom recurrence included greater time after surgery, preoperative dyspareunia, multiple fibroid surgeries, smoking after surgery, and preexisting diabetes. Factors positively correlated with achieving pregnancy included desiring pregnancy, prior pregnancy, greater time since surgery, and Caucasian race. Factors negatively correlated with pregnancy were advanced age and symptom recurrence. Conclusions. This paper, the first to examine symptom recurrence after RALM, demonstrates both short- and long-term effectiveness in providing symptom relief. Furthermore, RALM may have the potential to improve the chance of conception, even in a population at high risk of subfertility, with greater benefits among those who remain symptom-free. These findings require prospective validation.

    Robotic-assisted radical cystectomy (RARC) is a less invasive means of performing the radical cystectomy operation, which holds promise for improved patient morbidity. We review the history, technique and current literature pertaining to RARC and place the current results in context with the open procedure. All articles regarding RARC found in PubMed after January 2000 were examined. We selected articles that appeared in high-impact journals, had large patient population size (>80 patients), or were novel in technique or findings. We chose key laparoscopic articles to give reference to the history in transition to robotic radical cystectomy. In addition, we chose classic articles from open radical cystectomy to give reference regarding the newer robotic perioperative outcomes. Studies suggest that a 20-patient learning curve is needed to reach an operative time of 6.5 h, with 30 surgeries performed to reach lymph node counts in excess of 20 (International Robotic Cystectomy Consortium). The only randomized surgical trial comparing open and robotic techniques showed equivalent lymph node yield, which may be surgeon and volume dependent. Literature demonstrates lower estimated blood loss, transfusion rates, early return of bowel function and decreased complications in early small series. RARC and urinary diversion are still early in development and limited to centers with extensive robotic experience and volume, although adoption of the robotic approach is becoming more common. Early studies have shown promise to reduce complications with equivalent oncologic results.

    The use of robotic-assisted laparoscopic surgery (RALS) in gynecologic oncology is rising rapidly; however, the role of this modality in obstetrics has not been widely investigated. During pregnancy, the surgical management of adnexal masses is traditionally approached via laparotomy or laparoscopy. RALS offers a minimally invasive approach secondary to improved instrument dexterity and precision, 14-fold magnification, and 3-D imaging. For the pregnant patient, this translates into minimal manipulation of the gravid uterus, quicker recovery times, and potentially decreased maternal and fetal morbidity. Here we report six cases in which the da Vinci robotic surgical system (Intuitive Surgical Incorporated, Sunnyvale, CA) was used to perform an ovarian cystectomy during pregnancy. Pathology in all cases returned benign and each patient continued pregnancy without complications of surgery. In centers with the resources and adequately trained physicians, RALS offers the obstetric patient a safe and less invasive alternative to laparotomy or conventional laparoscopy. Although the advantages of robotic surgery are many, the limitations of this modality remain elevated equipment costs as well as the time investment necessary to train physicians.

    Full Text Available Background. Prostate cancer is the most common cancer diagnosed in men. As new focal therapies become more popular in treatment of prostate cancer, failure cases requiring salvage therapy with either surgical or other techniques are being reported. Objective. To report the options in treatment of prostate cancer after recurrence or failure of the primary treatment modality. Methods. We report a salvage robotic assisted laparoscopic radical prostatectomy (RALP for prostate cancer recurrence following high intensity focused ultrasound treatment (HIFU in the United States. Results. A 67-year-old man who underwent HIFU treatment for prostate adenocarcinoma 2 years prior was presented with a rising prostate specific antigen of 6.1 ng/mL to our clinic. A biopsy proven recurrent disease in the area of previous treatment documented the failure of treatment. The patient elected to undergo a salvage RALP. The operation time was 159 minutes. The patient was discharged from the hospital on postoperative day 1 with no complications. The catheter was removed on post-op day 10. The patient reserved sexual function and urinary continence. The PSA levels on 6 months’ follow-up are undetectable. Conclusions. Salvage RALP is an effective and safe treatment choice for recurrent prostate adenocarcinoma following failed HIFU treatment if operated by an experienced surgeon.

    An experienced surgical team, in general, and the surgeon assistant in particular are believed to play a critical role in the operation's safety and success. We sought to explore whether the assistant's seniority influences perioperative course following robot assisted laparoscopic radical prostatectomy (RALP). We reviewed our prospective registry database of RALP cases performed by a single surgeon who during the study period was beyond his learning curve. The following parameters were documented and analyzed: patient's age, body mass index (BMI), associated comorbidities, previous abdominal surgeries, assistant's identity, total and skin-to-skin operative time (tOT, ssOT, respectively), estimated blood loss (EBL), immediate post-operative complications, length of stay (LOS), and prostate weight per final pathology report. Univariate analysis and Spearman's correlation test were used to evaluate whether the assistant's seniority influenced perioperative course. Between the years 2011-2015, 106 consecutive cases were retrieved and analyzed. Prostate weight was found to be associated with longer tOT (Spearman's ρ = 0.34, p < 0.001), ssOT (0.3, p < 0.01) and increased EBL (0.28, p < 0.01). Patient's age, BMI, associated comorbidities, and previous abdominal surgeries were found to have no influence on neither tOT, ssOT nor EBL. Three assistants' subgroups were identified (seniors, PGY 1-3, PGY 4-6). The assistant's seniority was found to have no influence on tOT, ssOT, EBL, immediate post-operative complications and LOS. Same results were obtained following prostate size adjustments. The assistant's seniority has no influence on perioperative course following RALP. Consequently, given a highly experienced primary surgeon, a less experienced assistant can be safely incorporated into this procedure.

    Single-port access laparoscopic surgery has recently emerged as a method to improve morbidity and cosmetic benefit of conventional laparoscopic surgery. Herein, we report the experience of transumbilical incision laparoscopic sigmoidectomy with one assist port in a 71-year-old man who had developed recurrent sigmoid volvulus in these several years since his first visit to the hospital. The patient presented abdominal distension and severe constipation. A plain x-ray film and CT of the abdomen showed grossly distended sigmoid colon loops and stenosis of recto-sigmoid colon. Sigmoid volvulus associated with megacolon was diagnosed and emergence endoscopic decompression was performed. After his condition improved, transumbilical incision laparoscopic sigmoidectomy was carried out as the minimally invasive approach, due to the several risk of patient such as aging and pulmonary disorder. Postoperative course was uneventful and on postoperative visit to the hospital he reported resolution of abdominal distension.

    Robot-assisted laparoscopic prostatectomy is rapidly gaining favor as a minimally invasive method to surgically address prostate cancer. The sophisticated equipment and unique positioning requirements of this technology require exceptional preparation and attention to detail to minimize the chance of surgical complications. We present the case of a 57-year-old man who developed left calf compartment syndrome after (robot-assisted laparoscopic prostatectomy) requiring fasciotomies. We use this example to highlight specific areas of risk unique to the da Vinci Surgical System® using intraoperative photos to show danger areas as well as review basic positioning requirements common to all prolonged pelvic surgeries performed in Trendelenburg position.

    Studies detailing differences in positive surgical margin among open retropubic radical prostatectomy, laparoscopic radical prostatectomy, and robotic-assisted laparoscopic radical prostatectomy are lacking. A retrospective review of all prostatectomies with positive surgical margin performed at our center in 2007 disclosed 99 cases, 6 (5%) of which were reinterpreted cases as having negative margins. Ninety-three cases were, therefore, included, corresponding to 37 retropubic radical prostatectomies, 19 laparoscopic radical prostatectomies, and 37 robotic-assisted laparoscopic radical prostatectomies. The relationship of positive surgical margin characteristics to clinicopathologic parameters and biochemical recurrence was assessed. The most commonly found positive surgical margin site was the apex/distal third in all groups (62% retropubic prostatectomies, 79% laparoscopic prostatectomies, 60% robotic-assisted prostatectomies). Total linear length of positive surgical margin sites was significantly correlated with preoperative prostate-specific antigen, preoperative prostate-specific antigen density, pT stage, and tumor volume (P ≤ .001). We found no significant differences among the 3 groups with respect to total linear length, number of foci, laterality, or location of positive surgical margin. The rate of biochemical recurrence was also comparable in the 3 groups. On univariate analyses, biochemical recurrence was significantly associated with preoperative prostate-specific antigen values, preoperative prostate-specific antigen density, Gleason score, number of positive surgical margins, and total linear length of positive surgical margin (P ≤ .02). Only preoperative prostate-specific antigen density and number of positive surgical margin foci were statistically significant (P ≤ .03) independent predictors of biochemical recurrence. We found no significant difference in positive surgical margin characteristics or biochemical recurrence among the 3

    Full Text Available Rationale: One of the most complicated and unresolved problems in clinical medicine is the choice of an optimal method for organ-preservation treatment of uterine fibroids in women of childbearing age. Aim: To assess clinical efficacy of robot-assisted laparoscopic myomectomy. Materials and methods: The search was performed in PubMed, Embase, Trip, Cochrane, DocMe databases by keywords: “fibroids”, “robot”, “da Vinci”, “robotic myomectomy”, “robot-assisted myomectomy”. Results: We found 25 publications on robot-assisted laparoscopic myomectomy, including 6  papers on its reproductive outcomes (levels of evidence II–IV. Duration of robot-assisted surgery ranged from 132 to 261 minutes, intraoperative blood loss was in the range from 50 to 387 mL, postoperative hospital stay ranged from 1 to  3.9  days. There was a  lower percentage of intra- and postoperative complications after the robot-assisted interventions, compared to abdominal or classic laparoscopic access, as well as a lower percentage of conversion laparotomies compared to laparoscopy. Pregnancy rates after robotic myomectomy ranged from 16.7 to 69%. Only one case of uterine rupture after robot-assisted laparoscopic myomectomy has been described in the literature. Conclusion: Due to high cost of the method, the number of conducted studies is insufficient to evaluate the role of robotic technologies in the organ-preservation approach to uterine fibroids. Nevertheless, they suggest that robot-assisted laparoscopic myomectomy is justified in women of childbearing age who are planning pregnancy, with big centripetally growing intramural nodes and deformation of the uterine cavity. This technique on its own is an independent method for fertility restoration and could be the first step before the use of assisted reproductive technology.

    The aim of this study was to compare a simulator with the human cadaver model for hand-assisted laparoscopic colorectal skills acquisition training. An observational prospective comparative study was conducted to compare the laparoscopic surgery training models. The study took place during the laparoscopic colectomy training course performed at the annual scientific meeting of the American Society of Colon and Rectal Surgeons. Thirty four practicing surgeons performed hand-assisted laparoscopic sigmoid colectomy on human cadavers (n = 7) and on an augmented reality simulator (n = 27). Prior laparoscopic colorectal experience was assessed. Trainers and trainees completed independently objective structured assessment forms. Training models were compared by trainees' technical skills scores, events scores, and satisfaction. Prior laparoscopic experience was similar in both surgeon groups. Generic and specific skills scores were similar on both training models. Generic events scores were significantly better on the cadaver model. The 2 most frequent generic events occurring on the simulator were poor hand-eye coordination and inefficient use of retraction. Specific events were scored better on the simulator and reached the significance limit (p = 0.051) for trainers. The specific events occurring on the cadaver were intestinal perforation and left ureter identification difficulties. Overall satisfaction was better for the cadaver than for the simulator model (p = 0.009). With regard to skills scores, the augmented reality simulator had adequate qualities for the hand-assisted laparoscopic colectomy training. Nevertheless, events scores highlighted weaknesses of the anatomical replication on the simulator. Although improvements likely will be required to incorporate the simulator more routinely into the colorectal training, it may be useful in its current form for more junior trainees or those early on their learning curve.

    2005-10-01

    Full Text Available PURPOSE: Laparoscopic live donor nephrectomy has acquired an important role in the era of minimally invasive surgery. Laparoscopic harvesting of the right kidney is technically more challenging than that of the left kidney because of the short right renal vein and the need to retract the liver away from the right kidney. The aim of this article is to report our experience with right laparoscopic live donor nephrectomies. MATERIALS AND METHODS: We performed a retrospective review of 28 patients who underwent right laparoscopic donor nephrectomies at our service. Operative data and postoperative outcomes were collected, including surgical time, estimated blood loss, warm ischemia time, length of hospital stay, conversion to laparotomy and complications. RESULTS: The procedure was performed successfully in all 28 patients. The mean operative time was 83.8 minutes (range 45 to 180 minutes, with an estimated blood loss of 111.4 mL (range 40 to 350 mL and warm ischemia time of 3 minutes (range 1.5 to 8 minutes. No donor needed conversion to open surgery and all kidneys showed immediate function after implantation. The average time to initial fluid intake was 12 hours (range 8 to 24 hours. Two cases of postoperative ileus and a case of hematoma on the hand-port site were observed. The mean postoperative hospital stay was 3 days (range 1 to 7 days. CONCLUSIONS: Our data confirm the safety and feasibility of right laparoscopic donor nephrectomy and we believe that the right kidney should not be avoided for laparoscopic donor nephrectomy when indicated.

    Although reported in the literature, conventional laparoscopic approach for distal pancreatectomy is still lacking widespread acceptance. This might be due to two-dimensional vision and decreased range of motion to reach and safely dissect this highly vascularized retroperitoneal organ by laparoscopy. However, interest in minimally invasive access is growing ever since and the robotic system could certainly help overcome limitations of the laparoscopic approach in the challenging domain of pancreatic resection, notably in distal pancreatectomy. Robotic distal pancreatectomy with and without spleen preservation has been reported with encouraging outcomes for benign and borderline malignant disease. As a result of upgraded endowristed manipulation and three-dimensional visualization, improved outcome might be expected with the launch of the robotic system in the procedure of distal pancreatectomy. Our aim was thus to extensively review the current literature of robot-assisted surgery for distal pancreatectomy and to evaluate advantages and possible limitations of the robotic approach.

    To estimate the impact of body mass index (BMI) on the surgical outcomes of patients undergoing robotic-assisted total laparoscopic hysterectomy. Retrospective cohort study. Henry Ford Health System academic medical center (Henry Ford and Henry Ford West Bloomfield Hospitals) A total of 135 patients who underwent scheduled robotic-assisted total laparoscopic hysterectomy for benign indications, without concomitant urogynecologic procedures between January 2008 and June 2010. Patients underwent robotic-assisted total laparoscopic hysterectomy as the intention to treat. Two cases were converted to laparotomy. MEASUREMENTS & MAIN RESULTS: Electronic medical records of all patients that underwent robotic-assisted total laparoscopic hysterectomy at Henry Ford Health System were reviewed. Data on demographics, BMI (kg/m(2)), estimated blood loss, perioperative hemoglobin change, procedure duration, hospital length of stay, specimen weight, pathology, and postoperative complications were obtained. The women's median age was 45 years (range 30-68), 61.5% were black, and BMI ranged from 14.8-56.2 kg/m2; 23.4% of women were normal weight or less (BMI obese (BMI >30, n = 70) and 36 of these patients (27.1%) were morbidly obese (BMI ≥35). BMI did not correlate with procedure duration (Spearman r = .12, p = .16), length of stay (Spearman r = .10, p = .24), or estimated blood loss (Spearman r = .12, p =.18). Our analysis did not identify any meaningful associations between BMI and absolute change in hemoglobin. In addition BMI was not associated with an increase in major or minor complications. BMI is not associated with blood loss, duration of surgery, length of stay, or complication rates in patients undergoing robotic-assisted total laparoscopic hysterectomy. Robotic assistance may help surgeons overcome adverse outcomes sometimes found in obese patients. Copyright © 2011 AAGL. Published by Elsevier Inc. All rights reserved.

    Full Text Available Background. Recent studies have shown a lower risk of surgical site infections (SSI after laparoscopic distal gastrectomy compared to open surgery. This is a phase 2 study aiming to determine the incidence of SSI after laparoscopic distal gastrectomy without using antimicrobial prophylaxis (AMP. Methods. cT1N0 gastric cancers that were subject to laparoscopic distal gastrectomy were enrolled. Based on the unacceptable SSI incidence of ≥12.5% and the target SSI incidence of ≤5%, 105 patients were enrolled with an α of 0.05 and a power of 80% (ClinicalTrials.gov, NCT02200315. Results. In intention-to-treat analysis, patients did not reach the target SSI rate (12.4%, 95% confidence  interval=6.8%–19.8%. Of patients, 44 patients had a protocol violation, such as extended lymph node dissection (LND or inappropriate nonpharmacological SSI prevention measures. Per-protocol analysis excluding these patients (n=61 showed a SSI rate of 4.9%, which was within the target SSI range. Multivariate analysis revealed that extracorporeal anastomosis and extended LND were independent risk factors for SSI. Conclusions. This study failed to reach the target SSI rate without using AMP. However, per-protocol analysis suggests that no AMP might be feasible when limited LND and adequate SSI prevention measures were performed.

    2010-09-01

    Full Text Available Context: Central pancreatectomy has gained popularity in the past decade as treatment of choice for low malignant potential tumor in the midpancreas due to its ability to achieve optimal preservation of pancreatic parenchyma. Simultaneously, advancement in minimally invasive approach has contributed to numerous novel surgical techniques with significantly lower morbidity and mortality. With the purpose of improving patient outcomes, we describe a laparoscopic assisted central pancreatectomy with pancreaticogastrostomy as an alternative method to the previously described open central pancreatectomy with roux-en-y pancreaticojejunostomy reconstruction. Case Report: A 39 year old man presented to our clinic with a 2.5 cm neuroendocrine tumor at the neck of the pancreas. Laparoscopic assisted central pancreatectomy with pancreaticogastrostomy reconstruction was successfully performed. Operative time was 210 minutes with blood loss of 200 ml. Postoperative course was uneventful except for a minimal pancreatic leak which was controlled by an intraoperatively placed closed suction drain. At 2 week follow up, patient was asymptomatic with well preserved pancreatic endo and exocrine functions. Permanent pathology findings showed a well differentiated neuroendocrine tumor with negative margins and nodes. Conclusions: Laparoscopic assisted central pancreatectomy with pancreaticogastrostomy reconstruction is feasible and safe for a centrally located tumor. Laparoscopic assisted technique facilitates application of minimally invasive approach by increasing surgical feasibility in typically complex pancreatic operations.

Simultaneously, advancement in minimally invasive approach has contributed to numerous novel surgical techniques with significantly lower morbidity and mortality. With the purpose of improving patient outcomes, we describe a laparoscopic assisted central pancreatectomy with pancreaticogastrostomy as an alternative method to the previously described open central pancreatectomy with roux-en-y pancreaticojejunostomy reconstruction. Case Report: A 39 year old man presented to our clinic with a 2.5 cm neuroendocrine tumor at the neck of the pancreas. Laparoscopic assisted central pancreatectomy with pancreaticogastrostomy reconstruction was successfully performed. Operative time was 210 minutes with blood loss of 200 ml. Postoperative course was uneventful except for a minimal pancreatic leak which was controlled by an intraoperatively placed closed suction drain. At 2 week follow up, patient was asymptomatic with well preserved pancreatic endo and exocrine functions. Permanent pathology findings showed a well differentiated neuroendocrine tumor with negative margins and nodes. Conclusions: Laparoscopic assisted central pancreatectomy with pancreaticogastrostomy reconstruction is feasible and safe for a centrally located tumor. Laparoscopic assisted technique facilitates application of minimally invasive approach by increasing surgical feasibility in typically complex pancreatic operations.

    Full Text Available Abstract Background Transplantation is the only treatment offering long-term benefit to patients with chronic kidney failure. Live donor nephrectomy is performed on healthy individuals who do not receive direct therapeutic benefit of the procedure themselves. In order to guarantee the donor's safety, it is important to optimise the surgical approach. Recently we demonstrated the benefit of laparoscopic nephrectomy experienced by the donor. However, this method is characterised by higher in hospital costs, longer operating times and it requires a well-trained surgeon. The hand-assisted retroperitoneoscopic technique may be an alternative to a complete laparoscopic, transperitoneal approach. The peritoneum remains intact and the risk of visceral injuries is reduced. Hand-assistance results in a faster procedure and a significantly reduced operating time. The feasibility of this method has been demonstrated recently, but as to date there are no data available advocating the use of one technique above the other. Methods/design The HARP-trial is a multi-centre randomised controlled, single-blind trial. The study compares the hand-assisted retroperitoneoscopic approach with standard laparoscopic donor nephrectomy. The objective is to determine the best approach for live donor nephrectomy to optimise donor's safety and comfort while reducing donation related costs. Discussion This study will contribute to the evidence on any benefits of hand-assisted retroperitoneoscopic versus standard laparoscopic donor nephrectomy.

    Changming Huang

    Full Text Available The present study introduced a modified delta-shaped gastroduodenostomy (DSG technique and assessed the safety, feasibility and clinical results of this procedure in patients undergoing totally laparoscopic distal gastrectomy (TLDG for gastric cancer (GC.A total of 102 patients with distal GC undergoing TLDG with modified DSG between January 2013 and December 2013 were enrolled. A retrospective study was performed using a prospectively maintained comprehensive database to evaluate the results of the procedure. Univariate and multivariate analyses were performed to estimate the predictive factors for postoperative morbidity.The mean operation time was 150.6±30.2 min, the mean anastomosis time was 12.2±4.2 min, the mean blood loss was 48.2±33.2 ml, and the mean times to first flatus, fluid diet, soft diet and postoperative hospital stay were 3.8±1.3 days, 5.0±1.0 days, 7.4±2.1 days and 12.0±6.5 days, respectively. Two patients with minor anastomotic leakage after surgery were managed conservatively; no patient experienced any complications around the anastomosis, such as anastomotic stricture or anastomotic hemorrhage. Univariate analysis showed that age, gastric cancer with hemorrhage and cardiovascular disease combined were significant factors that affected postoperative morbidity (P<0.05. Multivariate analysis found that gastric cancer with hemorrhage was the independent risk factor for the postoperative morbidity (P = 0.042. At a median follow-up of 7 months, no patients had died or experienced recurrent or metastatic disease.The modified DSG was technically safe and feasible, with acceptable surgical outcomes, in patients undergoing TLDG for GC, and this procedure may be promising in these patients.

    The purpose of this paper is to evaluate laparoscopic-assisted cytoreduction for primary advanced ovarian cancer: feasibility, morbidity, response to chemotherapy and survival. All patients with presumed stage 3/4 primary ovarian cancer underwent attempted laparoscopic cytoreduction. All patients had CT evidence of omental metastasis and ascites. A five port (5-mm) transperitoneal approach was used. A bilateral salpingo-oophorectomy, supracervical hysterectomy and omentectomy were performed with the PlasmaKinetic (PK) cutting forceps. A laparoscopic 5-mm Argon-Beam Coagulator was used to coagulate tumor in the pelvis, abdominal peritoneum, intestinal mesentery, and diaphragm. Twenty-three cases (92%) were successfully cytoreduced laparoscopically without conversion to laparotomy. Median operative time was 2.3h and median blood loss was 340 cc. All tumors were debulked to less than 2 cm and 36% had no residual disease. Median length of stay was 1 day. Median VAS pain score was 4-discomforting. Six patients (24%) had post-operative complications, none grades 3-4. Median overall survival is 3.5 years. Laparoscopic-assisted cytoreduction for primary advanced ovarian cancer was successful, resulting in minimal morbidity, and acceptable survival. Copyright © 2011 Elsevier Inc. All rights reserved.

    Background. Although Billroth II (BII) reconstruction is simpler and faster than Billroth I or Roux-en-Y (RY) reconstruction in patients undergoing totally laparoscopic distal gastrectomy (TLDG), BII reconstruction is associated with several complications, including more severe bile reflux. BII Braun anastomosis may be a better alternative to RY reconstruction. Methods. This retrospective study included 56 consecutive patients who underwent TLDG for gastric cancer, followed by BII Braun or RY reconstruction, between January 2013 and December 2015. Surgical outcomes, including length of operation, quantity of blood lost, and postoperative complications, were compared in the two groups. Results. Clinicopathological characteristics did not differ between the BII Braun and RY groups. Mean length of operation was significantly longer in the RY than the BII Braun group (157.3 min versus 134.6 min, p gastritis in the remnant stomach in the two groups. Conclusions. B-II Braun anastomosis is a good alternative to RY reconstruction, reducing length of operation and ileus after TLDG. PMID:28163716

    This study compared surgical outcomes between patients undergoing laparoscopy-assisted distal gastrectomy (LADG) and those undergoing open distal gastrectomy (ODG) from the viewpoint of obesity. Between June 2002 and May 2008, 146 patients with preoperatively diagnosed early gastric cancer who underwent LADG (n = 90) or ODG (n = 56) were enrolled in this study and compared in terms of clinicopathological findings and operative outcome. The visceral fat area (VFA) and subcutaneous fat area (SFA) were assessed as identifiers of obesity using FatScan software. The relationship between obesity and operative outcomes after LADG and ODG was evaluated. There were no significant correlations between intraoperative blood loss (IBL) and any obesity-related factors, or between operation time (OT) and any obesity-related factors in the LADG group. There was a significant correlation between IBL and BMI (r = 0.486, P = 0.0001), IBL and VFA (r = 0.456, P = 0.0003), IBL and SFA (r = 0.311, P = 0.0193), OT and BMI (r = 0.406, P = 0.0017), OT and VFA (r = 0.314, P = 0.0178), and between OT and SFA (r = 0.382, P = 0.0034) in the ODG group. LADG may be a useful operative manipulation that is not influenced by obesity, whereas ODG may be influenced by obesity even after reaching the surgical plateau. (c) 2010 Wiley-Liss, Inc.

    Full Text Available Pelvic lymphocele is a potential complication of radical prostatectomy. Although lymphoceles often regress spontaneously, many may progress, precipitate clinical symptoms, and ultimately require intervention. To date, the best treatment of pelvic lymphoceles has not yet been fully defined. However, laparoscopic marsupialization is a definitive and efficacious surgical alternative to percutaneous drainage. It is effective, results in minimal patient morbidity, and allows for rapid recovery. We report our experience with management of clinically symptomatic pelvic lymphoceles following robotic-assisted prostatectomy using laparoscopic marsupialization.

    2010-01-01

    The use of new technology in surgery is enabling surgeons to operate solo in some procedures. The advantages are adequate work space on the operating table and maneuverability. However, although active and passive systems offer these advantages, the time required to relocate or reaccommodate optics and clean the laparoscope between operations has not been reduced. In addition, there is a perceptual difference between what the surgeon wishes to see and the proximity he/she achieves with the ac...

    Purpose: Patients with deranged renal functions have a number of associated factors which can impair healing of wound and increase postoperative morbidity. This study was conducted to assess the problems while managing ectopic pelvic kidney calculi using laparoscopic approach for percutaneous nephrolithotomy (PCNL) in chronic kidney disease patients. Subjects and Methods: Patients with calculi in ectopic kidney with increased serum creatinine level secondary to obstruction were included in the study. Initially, obstruction was relieved. Patients later underwent laparoscopic-assisted PCNL. Patients were monitored postoperatively. Results: Three patients with large renal calculi in ectopic pelvic kidney had presented in 2 years. Laparoscopic-assisted PCNL was done to remove the stone. Patients had persistent urine leak post-operatively. Mean duration for removal of nephrostomy tube and drain removal were 4.67 days and 6.67 days, respectively. These patients also had paralytic ileus for prolonged duration. Conclusion: Although laparoscopic assisted PCNL is an option in the management of patients with stone disease in ectopic pelvic kidney, prolonged time for healing of tract may increase postoperative morbidity in these patients with impaired renal function.

    This study compared the muscular activity in the surgeon's neck and upper limbs during robotic-assisted laparoscopic (R-Lap) surgery and conventional laparoscopic (C-Lap) surgery. Two surgeons performed the same procedure of R-Lap and C-Lap low anterior resection, and real-time surface electromyography was recorded in bilateral cervical erector spinae, upper trapezius (UT) and anterior deltoid muscles for over 60 min in each procedure. In one surgeon, forearm muscle activities were also recorded during robotic surgery. Similar levels of cervical muscle activity were demonstrated in both types of surgery. One surgeon showed much higher activity in the left UT muscle during robotic surgery. In the second surgeon, C-Lap was associated with much higher levels of muscle activity in both UT muscles. This may be related to the bilateral abducted arm posture required in maneuvering the laparoscopic instruments. In the forearm region, the "ulnaris" muscles for wrist flexion and extension bilaterally showed high amplitudes during robotic-assisted surgery. Robotic-assisted surgery seemed to demand a higher level of muscle work in the forearm region while greater efforts of shoulder muscles were involved during laparoscopic surgery. There are also individual variations in postural habits and motor control that can affect the muscle activation patterns. This study demonstrated a method of objectively examining the surgeon's physical workload during real-time surgery in the operating theatre, and further research should explore the surgeon's workload in a larger group of surgeons performing different surgical procedures.

    To describe a single-incision, laparoscopic-assisted technique for ovariohysterectomy and its application for treatment of mucometra and pyometra in dogs. Prospective case series. Seven dogs. Dogs were included if they had an open or closed pyometra or mucometra and an approximate uterine body diameter of less than 5 cm based on ultrasound or abdominal radiographs. Each dog underwent a laparoscopic-assisted ovariohysterectomy through a single-incision laparoscopic port. The procedure was performed in 6 dogs with pyometra and 1 dog with mucometra. Conversion to an open procedure was necessary in 1 dog with uterine rupture. A 2nd port was necessary in 1 dog to exteriorize the uterine body. Median uterine body diameter was 2.2 cm (range 2-3.9). The median surgical time was 85 minutes (range 40-110). Six of 7 dogs were released from the hospital at 1 day postoperative. Follow up ranged from 7 to 421 days and no complications were reported. A single-incision, laparoscopic-assisted technique for pyometra was feasible in dogs, given restricted case selection and experience with single-incision laparoscopy. © Copyright 2015 by The American College of Veterinary Surgeons.

    Kazuhito Yajima

    2012-01-01

    Full Text Available We report here a case of reexpansion pulmonary edema following laparoscopy-assisted distal gastrectomy (LADG for early gastric cancer. A 57-year-old Japanese woman with no preoperative comorbidity was diagnosed with early gastric cancer. The patient underwent LADG using the pneumoperitoneum method. During surgery, the patient was unintentionally subjected to single-lung ventilation for approximately 247 minutes due to intratracheal tube dislocation. One hour after surgery, she developed severe dyspnea and produced a large amount of pink frothy sputum. Chest radiography results showed diffuse ground-glass attenuation and alveolar consolidation in both lungs without cardiomegaly. A diagnosis of pulmonary edema was made, and the patient was immediately intubated and received ventilatory support with high positive end-expiratory pressure. The patient gradually recovered and was weaned from the ventilatory support on the third postoperative day. This case shows that single-lung ventilation may be a risk factor for reexpansion pulmonary edema during laparoscopic surgery with pneumoperitoneum.

    BACKGROUND: Rapid implementation of robotic transabdominal surgery has resulted in the need for re-evaluation of the most suitable form of anaesthesia. The overall objective of anaesthesia is to minimize perioperative risk and discomfort for patients both during and after surgery. Anaesthesia...... for patients undergoing robotic assisted surgery is different from anaesthesia for patients undergoing open or laparoscopic surgery; new anaesthetic concerns accompany robotic assisted surgery.

    The article made a comparative assessment of traumatic injury of open hand-assisted laparoscopic anterior resection of the rectum in lateral and spinal positions. The presented technique of hand-assisted laparoscopic colon and rectal surgery is simple. There are advantages in case of obesity presence (IMT more than 30 kg/m2), in significant shortening of the mesocolon and mesentery, high fixation of splenic flexure and intimate fixation of the spleen, in case of bad preparation of the bowels in partial intestinal obstruction or in case of emergency operation, big cancer size, expressed perifocal inflammation. A comparative analysis of dynamics of hormone stress content and metabolism (cortisol, adrenaline, thyrothrophic hormone) showed their expressed increase in blood during operation after traditional surgery. Less stressed reaction was noted after hand-assisted surgery, especially in overweight patients. An application of low invasive method allowed reduction of hemorrhage, pain syndrome, terms of patient's activation and restoration of intestinal motility after operation.

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    The inflammatory process associated with Crohn's disease often makes dissection difficult, even in open surgery. The aim of this study was to assess the technical feasibility, safety and indication of laparoscopic assisted procedures performed in patients with Crohn's disease. Records of patients undergoing surgical operation for Crohn's disease from 1993 to 1998 at our hospital were reviewed. Intestinal resection was performed laparoscopically in 24 patients (LAP) and by open technique in 23 patients (OPEN). No significant differences existed as to age, gender, body-mass-index and previous surgery. In the laparoscopic group, seven operations (CON) were converted to open laparotomy (29 %) because of large inflammatory mass and/or fistula. The mean intraoperative blood loss was significantly higher in CON- and OPEN-groups than in LAP-group (P<0. 01 ). Major complications occurred only in one patient who underwent laparoscopic assisted high anterior resection. Patients who underwent laparoscopic operation tolerated p.o. liquids sooner than patients who underwent open surgery (median: 2 vs. 5 day, P<0. 05). Compared with the CON- and OPEN-groups, patients in LAP-group had lower analgesic requirements (median: 3 vs. 6 and 5 day, P<0. 01). The median postoperative length of stay was significantly shorter in LAP-group than in OPEN-group (median: 11 vs. 14 day, P<0. 05). Our study showed that LAP is technically feasible for Crohn's disease. The preoperative correct diagnosis and selection of indications are very important, because the laparoscopic mobilization and resection may be difficult or impossible in patients with large fixed masses, multiple complx fistulas, or recurrent Crohn'sdisease.

    Full Text Available Aim: To visit the operative technique and to review the current published English literature on the technique, and outcomes following robot-assisted laparoscopic partial nephrectomy (RPN. Materials and Methods: We searched the published English literature and the PubMed (TM for published series of ′robotic partial nephrectomy′ (RPN using the keywords; robot, robot-assisted laparoscopic partial nephrectomy, laparoscopic partial nephrectomy, partial nephrectomy and laparoscopic surgery. Results: The search yielded 15 major selected series of ′robotic partial nephrectomy′; these were reviewed, tracked and analysed in order to determine the current status and role of RPN in the management of early renal neoplasm(s, as a minimally invasive surgical alternative to open partial nephrectomy. A review of the initial peri-operative outcome of the 350 cases of select series of RPN reported in published English literature revealed a mean operating time, warm ischemia time, estimated blood loss and hospital stay, of 191 minutes, 25 minutes, 162 ml and 2.95 days, respectively. The overall computed mean complication rate of RPN in the present select series was about 7.4%. Conclusions: RPN is a safe, feasible and effective minimally invasive surgical alternative to laparoscopic partial nephrectomy for early stage (T 1 renal neoplasm(s. It has acceptable initial renal functional outcomes without the increased risk of major complications in experienced hands. Prospective randomised, controlled, comparative clinical trials with laparoscopic partial nephrectomy (LPN are the need of the day. While the initial oncological outcomes of RPN appear to be favourable, long-term data is awaited.

    2014-01-01

    Background and Objectives: To determine perioperative outcome differences in patients undergoing robotic-assisted laparoscopic surgery (RALS) versus conventional laparoscopic surgery (CLS) for advanced-stage endometriosis. Methods: This retrospective cohort study at a minimally invasive gynecologic surgery center at 2 academically affiliated, urban, nonprofit hospitals included all patients treated by either robotic-assisted or conventional laparoscopic surgery for stage III or IV endometriosis (American Society for Reproductive Medicine criteria) between July 2009 and October 2012 by 1 surgeon experienced in both techniques. The main outcome measures were extent of surgery, estimated blood loss, operating room time, intraoperative and postoperative complications, and length of stay, with medians for continuous measures and distributions for categorical measures, stratified by body mass index values. Robotically assisted laparoscopy and conventional laparoscopy were then compared by use of the Wilcoxon rank sum, χ2, or Fisher exact test, as appropriate. Results: Among 86 conventional laparoscopic and 32 robotically assisted cases, the latter had a higher body mass index (27.36 kg/m2 [range, 23.90–34.09 kg/m2] versus 24.53 kg/m2 [range, 22.27–26.96 kg/m2]; P laparoscopy patients. After body mass index stratification, obese patients varied in operating room time (282.5 minutes [range, 224–342 minutes] for robotic-assisted laparoscopy versus 174 minutes [range, 130–270 minutes] for conventional laparoscopy; P laparoscopy groups. Conclusion: Despite a higher operating room time, robotic-assisted laparoscopy appears to be a safe minimally invasive approach for patients, with all other perioperative outcomes, including intraoperative and postoperative complications, comparable with those in patients undergoing conventional laparoscopy.

    The most important factors that have facilitated the development of laparoscopic surgery (LS) are technological innovations and the vision of a small number of surgeons who took advantage of these advances. There are few surgical innovations that have stimulated such controversies and concerns and have raised so many medico-legal issues as LS. Although much progress has been made in LS, some important controversies remain unresolved, which are reviewed in the present article: 1. Evolution of the laparoscopic approach: total laparoscopic approach through positive-pressure capnoperitoneum, gasless laparoscopy, hand-assisted laparoscopy, and laparoscopy-assisted surgery. 2. Classification of current instrumental technology in laparoscopic surgery: a) facilitating instruments (high-power ultrasonic dissection systems); b) enabling instruments (endostapling and linear dissection devices), and c) complementary instruments: the Da Vinci robotic system. 3. Current laparoscopic surgical practice: a) interventions that definitively improve the patient's outcome (diagnostic and staging laparoscopy, cholecystectomy, adrenalectomy, splenectomy, antireflux surgery, cardiomyotomy, bariatric surgery, laparoscopic colon surgery, living donor nephrectomy); b) interventions that seem to be useful to the patient (distal pancreatic surgery, laparoscopic left hepatic resection, gastric and esophageal resections, hernioplasty), and c) interventions with uncertain benefit (right hepatectomy, pancreatoduodenectomy). 4. Future lines of development: video monitors in laparoscopic surgery, endoluminal surgery, robotic surgery, and finally, 5. Problems faced by laparoscopic surgery: quality guarantees in laparoscopic surgery, training the future laparoscopic generation, and allocation of sufficient material and human resources to laparoscopic surgery and its subspecialties.

    To find the consequences of laparoscopically assisted vaginal hysterectomy (LAVH) and total laparoscopic hysterectomy (TLH) for sexual functions in preoperatively asymptomatic women. Prospective study. Department of Obstetrics and Gynecology, 1st Faculty of Medicine, Charles University and General Teaching Hospital in Prague. In 100 women without subjective complaints hysterectomy was performed for benign uterine pathology. In all the women the uterus weighted less than 250 g, there were no salpingooophorectomies and no perioperative complications. Women were alternativelly assigned for LAVH (n = 50) or TLH (n = 50). Clinical documentation and questionnaires about sexual functions were evaluated in 87 women (in 40 women after LAVH and in 47 after TLH) 18 months after surgery or later. According to our findings the type of surgery did not influence the frequency of sexual activity after surgery, there was no change in sexual manners using during coitus as well as no change in preferred way how to reach the sexual arousal (clitoridally, vaginally or combined). The type of surgery did not influence frequency, quality and duration of orgasm. From all the evaluated parameters there were only two significantly different: the presence of postoperative sexual activity (positive answer in all women from LAVH group and only in 85% women from TLH group, F test, p = 0.009) and the frequency of sexual satisfaction (in terms of both increase and also decrease in TLH group chi2 8,376, p = 0.015). The type of laparoscopic hysterectomy (LAVH or TLH) does not significantly affect the sexual functions (frequency of sexual satisfaction, type of sexual arousability, intensity and duration of orgasm) in preoperatively asymptomatic women.

The first is a patient that ESWL and previous percutaneous lithotripsy have failed, with pelvic kidney where laparoscopic dissection of renal pelvis was carried out followed by nephroscopy utilizing the 30 Fr rigid nephroscope to remove the calculus. Ideal angle between the major axis of renal pelvis and the rigid nephroscope to allow success with this technique was 60-90 grades. In the second case, the kidney had a dilated infundibulum. Results: The operative time was 180 minutes for both procedures. No significant blood loss or perioperative complications occurred. The bladder catheter was removed in the postoperative day 1 and Penrose drain on day 2 when patients were discharged. The convalescence was completed after 3 weeks. Patients were stone free without symptons in one year of follow-up. Conclusions: Laparoscopic-assisted rigid nephroscopy performed via tranpyelic approach can be done safely with proper patient selection and adherence to standard laparoscopic surgical principles. This approach is an alternative in cases where flexible endoscope is not available and when standard procedure is unlikely to produce a stone-free status.

    AIM: To describe the use of hand-assisted laparoscopic surg-ery (HALS) as an alternative to open conversion for complex gall-stone diseases, including Mirizzi syndrome (MS) and mimic MS.METHODS: Five patients with MS and mimic MS of 232 consecutive patients undergoing laparoscopic cholecystectomies were analyzed. HALS without a hand-port device was performed as an alternative to open conversion if the anatomy was still unclear after the neck of the gallbladder was reached.RESULTS: HALS was performed on three patients with MS type Ⅰ and 2 with mimic MS owing to an undear or abnormal anatomy, or an unusual circumstance in which an impacted stone was squeezed out from the infundibulum or the aberrant cystic duct impossible with laparoscopic approach. The median operative time was 165 min (range, 115-190 min). The median hand-assisted time was 75 min (range, 65-100 min). The median postoperative stay was 4 d (range, 3-5 d). The postoperative course was uneventful, except for 1 patient complicated with a minor incision infection. CONCLUSION: HALS for MS type Ⅰ and mimic MS is safe and feasible. It simplifies laparoscopic procedure, and can be used as an alternative to open conversion for complex gallstone diseases.

    Full Text Available INTRODUCTION: Bilateral ureteropelvic junction (UPJ obstruction occurs infrequently. When surgical management is deemed necessary, staged pyeloplasties traditionally have been recommended to minimize the morbidity associated with performing procedures concurrently. With the advent of robotic-assistance, concurrent surgical management can more readily be performed laparoscopically. In this report, we evaluated the safety and outcome of managing patients with bilateral UPJ obstruction with concurrent robotic-assisted laparoscopic pyeloplasty. MATERIALS AND METHODS: We performed a retrospective review of five patients with bilateral ureteropelvic junction obstruction who underwent concurrent bilateral robotic-assisted pyeloplasties at our institution between October 2003 and April 2007. Technical consideration for patient positioning, robotic set-up, port placement, and the use of a hitch stitches was assessed. The operative time, complications, analgesic needs, length of hospitalization, and overall success of the procedure were evaluated. RESULTS: Operative time ranged from 235 to 541 minutes (mean = 384. Estimated blood loss was 5-100 cc (mean = 48.0. Length of hospitalization ranged from 1.3 to 3.6 days (mean = 2.4. Ureteral stents were removed 3-8 weeks postoperatively. There were no complications. All kidneys demonstrated decreased hydronephrosis on postoperative ultrasound or improved drainage parameters on diuretic renography or IVP. CONCLUSIONS: Simultaneous bilateral robotic-assisted laparoscopic pyeloplasties utilizing 4-port access is feasible and safe. It provides an effective method of managing patients with bilateral UPJ obstruction, avoiding the burden and morbidity of performing staged surgeries.

    Partial nephrectomy is the treatment of choice for T1a tumours. The open approach is still the standard method. Robot-assisted laparoscopic surgery offers advantages that are applicable to partial nephrectomy, such as the use of the Firefly® system with near-infrared fluorescence. To demonstrate the implementation of fluorescence in nephron-sparing surgery. This case concerned a 37-year-old female smoker, with obesity. The patient had a right kidney tumour measuring 31 mm, which was found using tomography. She therefore underwent robot-assisted laparoscopic partial nephrectomy, with a warm ischaemia time of 22 minutes and the use of fluorescence with the Firefly® system to guide the resection. There were no complications. The tumour was a pT1aN0M0 renal cell carcinoma, with negative margins. Robot-assisted renal laparoscopic surgery is employed for nephron-sparing surgery, with good oncological and functional results. The combination of the Firefly® technology and intraoperative ultrasound can more accurately delimit the extent of the lesion, increase the negative margins and decrease the ischaemia time. Near-infrared fluorescence in robot-assisted partial nephrectomy is useful for guiding the tumour resection and can potentially improve the oncological and functional results. Copyright © 2015 AEU.

    To evaluate surgical outcome in a consecutive series of patients with conventional and robot assisted total laparoscopic hysterectomy. A retrospective cohort study was performed among patients with benign and malignant indications for a laparoscopic hysterectomy. Main surgical outcomes were operation room time and skin to skin operating time, complications, conversions, rehospitalisation and reoperation, estimated blood loss and length of hospital stay. A total of 294 patients were evaluated: 123 in the conventional total laparoscopic hysterectomy (TLH) group and 171 in the robot TLH group. After correction for differences in basic demographics with a multivariate linear regression analysis, the skin to skin operating time was a significant 18 minutes shorter in robot assisted TLH compared to conventional TLH (robot assisted TLH 92m, conventional TLH 110m, p0.001). The presence or absence of previous abdominal surgery had a significant influence on the skin to skin operating time as did the body mass index and the weight of the uterus. Complications were not significantly different. The robot TLH group had significantly less blood loss and lower rehospitalisation and reoperation rates. This study compares conventional TLH with robot assisted TLH and shows shorter operating times, less blood loss and lower rehospitalisation and reoperation rates in the robot TLH group.

    Robotic assisted laparoscopic pyeloplasty is an emerging, minimally invasive alternative to open pyeloplasty in children for ureteropelvic junction obstruction. The procedure is associated with smaller incisions and shorter hospital stays. To our knowledge previous outcome analyses have not included human capital calculations, especially regarding loss of parental workdays. We compared perioperative factors in patients who underwent robotic assisted laparoscopic and open pyeloplasty at a single institution, especially in regard to human capital changes, in an institutional cost analysis. A total of 44 patients 2 years old or older from a single institution underwent robotic assisted (37) or open (7) pyeloplasty from 2008 to 2010. We retrospectively reviewed the charts to collect demographic and perioperative data. The human capital approach was used to calculate parental productivity losses. Patients who underwent robotic assisted laparoscopic pyeloplasty had a significantly shorter average hospital length of stay (1.6 vs 2.8 days, p human capital gains, eg decreased lost parental wages, and lower hospitalization expenses. Future comparative outcome analyses in children should include financial factors such as human capital loss, which can be especially important for families with young children.

    Full Text Available CONTEXT AND PURPOSE: Partial nephrectomy has become the standard of care for renal tumors less than 4 cm in diameter. Controversy still exists, however, regarding the best surgical approach, especially when minimally invasive techniques are taken into account. Robotic-assisted laparoscopic partial nephrectomy (RALPN has emerged as a promising technique that helps surgeons achieve the standards of open partial nephrectomy care while offering a minimally invasive approach. The objective of the present study was to describe our initial experience with robotic-assisted laparoscopic partial nephrectomy and extensively review the pertinent literature. MATERIALS AND METHODS: Between August 2009 and February 2010, eight consecutive selected patients with contrast enhancing renal masses observed by CT were submitted to RALPN in a private institution. In addition, we collected information on the patients' demographics, preoperative tumor characteristics and detailed operative, postoperative and pathological data. In addition, a PubMed search was performed to provide an extensive review of the robotic-assisted laparoscopic partial nephrectomy literature. RESULTS: Seven patients had RALPN on the left or right sides with no intraoperative complications. One patient was electively converted to a robotic-assisted radical nephrectomy. The operative time ranged from 120 to 300 min, estimated blood loss (EBL ranged from 75 to 400 mL and, in five cases, the warm ischemia time (WIT ranged from 18 to 32 min. Two patients did not require any clamping. Overall, no transfusions were necessary, and there were no intraoperative complications or adverse postoperative clinical events. All margins were negative, and all patients were disease-free at the 6-month follow-up. CONCLUSIONS: Robotic-assisted laparoscopic partial nephrectomy is a feasible and safe approach to small renal cortical masses.Further prospective studies are needed to compare open partial nephrectomy with

    Cystinuria, a rare autosomal recessive disease characterized by a defect in cystine renal reabsorption, can often determine complex cystine renal calculi, leading to important complications such as urinary obstruction, urinary infections, and impaired kidney function. Complex kidney stones can have a difficult management and can be very arduous to treat. We present the case of a 20-year-old Jeowah's witness woman with complex cystine renal stones treated with combined robot-assisted laparoscopic pyelolithotomy and intraoperative renoscopy. The combination of robot-assisted laparoscopic pyelolithotomy and intraoperative renoscopy can be useful to achieve an immediate high stone clearance rate also in complex renal stones. This combined technique could be indicated to minimize intraoperative bleeding. Moreover, it can also be used in pediatric cases or when there is no ureteral compliance. However, this strategy can be performed only in hospital referral centers by expert surgeons.

    This paper presents a method for generating branching pattern reports of abdominal blood vessels for laparoscopic gastrectomy. In gastrectomy, it is very important to understand branching structure of abdominal arteries and veins, which feed and drain specific abdominal organs including the stomach, the liver and the pancreas. In the real clinical stage, a surgeon creates a diagnostic report of the patient anatomy. This report summarizes the branching patterns of the blood vessels related to the stomach. The surgeon decides actual operative procedure. This paper shows an automated method to generate a branching pattern report for abdominal blood vessels based on automated anatomical labeling. The report contains 3D rendering showing important blood vessels and descriptions of branching patterns of each vessel. We have applied this method for fifty cases of 3D abdominal CT scans and confirmed the proposed method can automatically generate branching pattern reports of abdominal arteries.

    Objectives: To evaluate the feasibility and efficacy of robotic-assisted laparoscopic pyeloplasty. Laparoscopic pyeloplasty has been shown to have a success rate comparable to that of the open surgical approach. However, the steep learning curve has hindered its acceptance into mainstream urologic practice. The introduction of robotic assistance provides advantages that have the potential to facilitate precise dissection and intracorporeal suturing. Methods: A total of 50 patients underwent robotic-assisted laparoscopic dismembered pyeloplasty. A four-trocar technique was used. Most patients were discharged home on day 1, with stent removal at 3 weeks. Patency of the ureteropelvic junction was assessed in all patients with mercaptotriglycylglycine Lasix renograms at 1, 3, 6, 9, and 12 months, then every 6 months for 1 year, and then yearly. Results: Each patient underwent a successful procedure without open conversion or transfusion. The average estimated blood loss was 40 ml. The operative time averaged 122 minutes (range 60 to 330) overall. Crossing vessels were present in 30% of the patients and were preserved in all cases. The time for the anastomosis averaged 20 minutes (range 10 to 100). Intraoperatively, no complications occurred. Postoperatively, the average hospital stay was 1.1 days. The stents were removed at an average of 20 days (range 14 to 28) postoperatively. The average follow-up was 11.7 months; at the last follow-up visit, each patient was doing well. Of the 50 patients, 48 underwent one or more renograms, demonstrating stable renal function, improved drainage, and no evidence of recurrent obstruction. Conclusions: Robotic-assisted laparoscopic pyeloplasty is a feasible technique for ureteropelvic junction reconstruction. The procedure provides a minimally invasive alternative with good short-term results.

    Objective. To analyze the learning curves of the different stages of robotic-assisted laparoscopic hysterectomy. Design. Retrospective analysis. Design Classification. Canadian Task Force classification II-2. Setting. Kaohsiung Medical University Hospital, Kaohsiung, Taiwan. Patient Intervention. Women receiving robotic-assisted total and subtotal laparoscopic hysterectomies for benign conditions from May 1, 2013, to August 31, 2015. Measurements and Main Results. The mean age, body mass index (BMI), and uterine weight were 46.44 ± 5.31 years, 23.97 ± 4.75 kg/m2, and 435.48 ± 250.62 g, respectively. The most rapid learning curve was obtained for the main surgery console stage; eight experiences were required to achieve duration stability, and the time spent in this stage did not violate the control rules. The docking stage required 14 experiences to achieve duration stability, and the suture stage was the most difficult to master, requiring 26 experiences. BMI did not considerably affect the duration of the three stages. The uterine weight and the presence of adhesion did not substantially affect the main surgery console time. Conclusion. Different stages of robotic-assisted laparoscopic hysterectomy have different learning curves. The main surgery console stage has the most rapid learning curve, whereas the suture stage has the slowest learning curve. PMID:28373977

    The anorectal anomalies consist in a complex group of birth defects. Laparoscopic-assisted anorectoplasty improved visualization of the rectal fistula and the ability to place the pull-through segment within the elevator muscle complex with minimal dissection. There is no consensus on how the fistula should be managed. To evaluate the laparoscopic-assisted anorectoplasty and the treatment of the rectal urinary fistula by a bipolar sealing device. It was performed according to the original description by Georgeson1. Was used 10 mm infraumbilical access portal for 30º optics. The pneumoperitoneum was established with pressure 8-10 cm H2O. Two additional trocars of 5 mm were placed on the right and left of the umbilicus. The dissection started on peritoneal reflection using Ligasure(r). With the reduction in the diameter of the distal rectum was identified the fistula to the urinary tract. The location of the new anus was defined by the location of the external anal sphincter muscle complex, using electro muscle stimulator externally. Finally, it was made an anastomosis between the rectum and the new location of the anus. A Foley urethral probe was left for seven days. Seven males were operated, six with rectoprostatic and one with rectovesical fistula. The follow-up period ranged from one to four years. The last two patients operated underwent bipolar sealing of the fistula between the rectum and urethra without sutures or surgical ligation. No evidence of urethral leaks was identified. There are benefits of the laparoscopic-assisted anorectoplasty for the treatment of anorectal anomaly. The use of a bipolar energy source that seals the rectal urinary fistula has provided a significant decrease in the operating time and made the procedure be more elegant. As anomalias anorretais consistem de um grupo complexo de defeitos congênitos.

    2015-01-01

    Full Text Available Background: To open vaginal cavity to the pelvic floor is part of surgical treatment for urogenital sinus (UGS in girls with congenital adrenal hyperplasia (CAH. For high UGS, this operative procedure can be challenging and may jeopardise urinary continence. Combined perineal and laparoscopic approaches could be useful to minimise perineal dissection and to facilitate the vaginal lowering. Patients and Methods: We report the procedure of a laparoscopic-assisted vaginal pull-through for supra-sphincteric UGS in a 5-year-old girl with CAH. Laparoscopic dissection of the vagina from the posterior wall of the bladder and urethra, division of the confluence and vaginal pull-through to the perineum are described. Discussion: The technique is derived from laparoscopic-assisted treatment for high ano-rectal malformations. Compared with current procedures for treatment for high UGS, laparoscopic-assisted approach allows mobilising vagina with minimal dissection of perineum and complete preservation of urethra. Another major advantage is to provide a direct vision for dissection of the space between rectum and urethra prior to vaginal pull-through. Conclusion: Laparoscopic-assisted vaginal pull-through appears to be an interesting approach for high UGS in CAH patients, reducing dissection and risk of urinary incontinence. This new approach needs to be strengthened by other cases.

    Robot-assisted surgical systems have been introduced to improve the outcome of minimally invasive surgery. These systems also have the potential to improve ergonomics for the surgeon during endoscopic surgery. This study aimed to compare the user's mental and physical comfort in performing standard laparoscopic and robot-assisted techniques. Surgical performance also was analyzed. In this study, 16 surgically inexperienced participants performed three tasks using both a robotic system and standard laparoscopic instrumentation. Distress was measured using questionnaires and an ambulatory monitoring system. Surgical performance was analyzed with time-action analysis. The physiologic parameters (p = 0.000), the questionnaires (p = 0.000), and the time-action analysis (p = 0.001) favored the robot-assisted group in terms of lower stress load and an increase in work efficiency. In this experimental setup, the use of a robot-assisted surgical system was of value in both cognitive and physical stress reduction. Robotic assistance also demonstrated improvement in performance.

    Total laparoscopic hysterectomy (TLH) in obese patients is challenging. We sought to evaluate whether total laparoscopic hysterectomies using the da Vinci robotic system in obese patients, in comparison with non-obese patients, is a reasonable surgical approach. One-hundred consecutive robot-assisted TLHs were performed over a 17-month period. Obesity was not a contraindication to robotic surgery, assuming adequate respiratory function to tolerate Trendelenburg position and, for cancer cases, a small enough uterus to allow vaginal extraction without morcellation. Data were prospectively collected on patient characteristics, total operative time, hysterectomy time, estimated blood loss, length of stay, and complications. Outcomes with non-obese and obese women were compared. The median age, weight, and BMI of the 100 patients who underwent robot-assisted TLH was 57.6 years (30.0-90.6), 82.1 kg (51.9-159.6), and 30.2 kg/m(2) (19.3-60.2), respectively. Fifty (50%) patients were obese (BMI ≥ 30); 22 patients were morbidly obese (BMI ≥ 40). There was no increase in complications (p = 0.56) or blood loss (p = 0.44) with increasing BMI. While increased BMI was associated with longer operative times (p = 0.05), median time increased by only 36 min when comparing non-obese and morbidly obese patients. Median length of stay was one day for all weight categories (p = 0.42). Robot-assisted TLH is feasible and can be safely performed in obese patients. More data are needed to compare robot-assisted TLH with other hysterectomy techniques in obese patients. Nonetheless, our results are encouraging. Robot-assisted total laparoscopic hysterectomy may be the preferred technique for appropriately selected obese patients.

    ABSTRACT Background Robotic-assisted radical prostatectomy (RALP) is a minimally invasive procedure that could have a reduced learning curve for unfamiliar laparoscopic surgeon. However, there are no consensuses regarding the impact of previous laparoscopic experience on the learning curve of RALP. We report on a functional and perioperative outcome comparison between our initial 60 cases of RALP and last 60 cases of laparoscopic radical prostatectomy (LRP), performed by three experienced laparoscopic surgeons with a 200+LRP cases experience. Materials and Methods Between January 2010 and September 2013, a total of 60 consecutive patients who have undergone RALP were prospectively evaluated and compared to the last 60 cases of LRP. Data included demographic data, operative duration, blood loss, transfusion rate, positive surgical margins, hospital stay, complications and potency and continence rates. Results The mean operative time and blood loss were higher in RALP (236 versus 153 minutes, p<0.001 and 245.6 versus 202ml p<0.001). Potency rates at 6 months were higher in RALP (70% versus 50% p=0.02). Positive surgical margins were also higher in RALP (31.6% versus 12.5%, p=0.01). Continence rates at 6 months were similar (93.3% versus 89.3% p=0.43). Patient’s age, complication rates and length of hospital stay were similar for both groups. Conclusions Experienced laparoscopic surgeons (ELS) present a learning curve for RALP only demonstrated by longer operative time and clinically insignificant blood loss. Our initial results demonstrated similar perioperative and functional outcomes for both approaches. ELS were able to achieve satisfactory oncological and functional results during the learning curve period for RALP. PMID:27136471

    Full Text Available Adult intussuception is rare and laparotomy is required in most of the cases due to the potential pathologic underlying reasons. Although it is technically challenging, single-incision laparoscopic surgery can work as an alternative to laparotomy. Here we report the case of a 45-year-old man with intermittent right lower quadrant abdominal pain for 1 month. Abdominal enhanced computed tomography (CT scan was performed and ileo-ileal intussusception was found, with lipoma as a likely leading point. Ileal resection was performed using the single-incision laparoscopic-assisted technique. Multiple trocars in the umbilical incision technique and conventional instruments were used. After identification of the ileo-ileal intussusception, the involved small bowel was extracted from the umbilical incision, and resection and anastomosis were performed extracoporeally. The operation time was 65 min and the post-operative hospital stay was 2 days. The patient recovered uneventfully, with better cosmetic results.

    To determine the feasibility and safety of laparoscopically assisted vaginal hysterectomy in the treatment of presumed stage I endometrial cancer. This was a prospective cohort study without randomization of 182 consecutive patients who underwent surgery for early endometrial cancer or atypical hyperplasia at the West Kent Gynaecological Oncology Centre, UK. Seventy-four had laparoscopically assisted vaginal hysterectomy and bilateral salpingo-oophorectomy (BSO), and 108 had a total abdominal hysterectomy and bilateral salpingo-oophorectomy. Lymphadenectomy was performed in 153 patients, and lymph node sampling was performed in 2 patients. Twenty-seven patients with serous papillary endometrial cancer in addition had an omentectomy. The groups were compared for epidemiological and clinical characteristics, surgical outcomes, hospital stay, lymph node harvest, and intraoperative and postoperative complications. The patients in the laparoscopy group had less blood loss, similar number of lymph nodes removed, less need for analgesia, and shorter hospital stay but longer operative time than those treated by laparotomy. In our study, we had 4 conversions (5.4%) from laparoscopy to laparotomy. Twenty-eight (41%) patients who had laparoscopic surgery were obese (body mass index [BMI] >30 kg/m2). Postoperative complications were more common in the laparotomy group (34%) than in the laparoscopy group (6%). No major complications occurred in the laparoscopy group. Wound infection was the most common complication in laparotomy patients, and this invariably happened to obese patients (BMI >30 kg/m2). There were 6 readmissions, all from the laparotomy group. Laparoscopic surgery is a safe and reliable alternative to open surgery in the management of early endometrial cancer patients, with significantly reduced hospital stay and complications, especially in those patients with an elevated BMI.

    To compare the functional outcomes and complication rates following laparoscopic sacrocolpopexy (LS) with those occurring in robot-assisted laparoscopic sacrocolpopexy (RALSCP) in obese women. A comparative retrospective multicentre study was made, involving 39 obese women (BMI≥30 kg/m2) who underwent LS, and 17 obese women who underwent RASCLP. The operative parameters (length of operation, associated procedures, complication rate and length of hospitalization) and the objective and subjective results were evaluated at 12 months follow-up. The median (IQR) BMI was 30.5 kg/m2 (30-32) in the LS group vs 31.6 kg/m2 (30-34) in the RALSCP group (P=0.402). The anatomical results were comparable in both groups (LS vs RALSCP): post-operative stage of prolapse (POP-Q-ICS): stage 0-1: 34/39 (88%) vs 16/17 (94.1%), P=0.7; stage 2: 4/39 (10%) vs 0/17 (0%), P=0.7; stage 3-4: 1/39 (2%) vs 1/17 (5.9%), P=0.7. The complication rate was similar in both groups (LS vs RALSCP): bladder injury 2.5% (1/39) vs 0% (0/17), P=0.6, laparoconversion 5.1% (2/39) vs 5.9% (1/17), P=0.5. The overall reoperation rate was (LS vs RALSCP): 18% (7/39) vs 5.9% (1/17), P=0.4. Laparoscopic sacrocolpopexy and robot-assisted laparoscopic sacrocolpopexy have equal results in obese women. The complication rates and outcomes appear to be similar in both groups of obese women. 3. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Full Text Available PURPOSE:Our first 91 consecutive cases undergoing a robotic assisted cystectomy were analyzed regarding perioperative outcomes, pathological stages and surgical complications. MATERIALS AND METHODS: Between 2007 and 2010 a total of 91 patients (76 male and 15 female, 86 with clinically localized bladder cancer and 5 with non-urothelial tumors underwent a radical robotic assisted cystectomy. We analyzed the perioperative factors, length of hospital stay, pathological outcomes and complication rates. RESULTS: Mean age was 65.6 years (range 28 to 82. Among the 91 patients, 68 were submitted to an ileal conduit and 23 to a neobladder procedure for urinary diversion. Mean operating time was 412 min (range: 243-618 min. and mean blood loss was 294 mL (range: 50-2000 mL. In 29% of the cases with urothelial carcinoma the T-stage was pT1 or less, 38% were pT2; 26% and 7% were classified as pT3 and pT4, respectively. 14% of cases had lymph node positive disease. Mean number of lymph nodes removed was 15 (range 4 to 33. Positive surgical margins occurred in 2 cases (2.1%. Mean days to flatus were 2.13, bowel movement 2.88 and inpatient stay 18.8 (range: 10-33. There were 45 postoperative complications with 11% major (Clavien grade 3 or higher. At a mean follow-up of 15 months 10 patients had disease recurrence and 6 died of the disease. CONCLUSIONS: Our experience demonstrates that robotic assisted radical cystectomies for the treatment of bladder cancers seems to be very promising regarding surgical and oncological outcomes.

    2008-01-01

    Full Text Available Robotic-assisted laparoscopy (RAL has become a promising means for performing correction of vesicoureteral reflux disease in children through both intravesical and extravesical techniques. We describe the importance of patient selection, intraoperative patient positioning, employing certain helpful techniques for exposure, and recognizing the limitations and potential complications of robotic reimplant surgery. As more clinicians embrace robotic surgery and more urology residents are trained in robotics, we anticipate an expansion of the applications of robotics in children. We believe that it is necessary to develop robotic surgery curricula for novice roboticists and residents so that patients may experience improved surgical outcomes.

    Laparoscopy-assisted distal gastrectomy (LADG) for gastric cancer may prevent the loss of body weight and lean body mass resulting from reduced surgical stress in comparison to open distal gastrectomy (ODG). A multicenter phase III trial conducted by the Japan Clinical Oncology Group (JCOG0912 trial) was performed to confirm the non-inferiority of LADG to ODG for stage I gastric cancer in terms of relapse-free survival. This study was performed as a single-institution exploratory analysis using the data of the patients from our hospital who were enrolled in the JCOG0912 phase III trial. Body weight and lean body mass were evaluated using a bioelectrical impedance analyzer within 1 week before and at 1 week, 1 month, and 3 months after surgery. One-hundred six patients were randomized to undergo ODG (54 patients) or LADG (51 patients). Body weight loss at 1 week, 1 month, and 3 months was -3.0%, -4.9%, and -5.4%, respectively, in the ODG group and -2.7%, -4.3%, and -5.7%, respectively, in the LADG group; the differences were not statistically significant (p = 0.330, 0.166, and 0.656, respectively). Lean body mass loss at 1 week, 1 month, and 3 months was -2.8%, -4.1%, and -2.3%, respectively, in the ODG group and -2.7%, -2.9%, and -3.0%, respectively, in the LADG group; the differences were not statistically significant (p = 0.610, 0.413, and 0.925, respectively). The laparoscopic approach did not attenuate the loss of body weight and lean body mass in comparison to patients who underwent open distal gastrectomy for gastric cancer.

    Radical prostatectomy surgery (RP) is the gold standard for treatment of localized prostate cancer (PCa). Recently, emergence of minimally invasive techniques such as Laparoscopic Radical Prostatectomy (LRP) and Robot-Assisted Laparoscopic Radical Prostatectomy (RARP) has improved the outcomes for prostatectomy. However, it remains difficult for the surgeons to make informed decisions regarding resection margins and nerve sparing since the location of the tumor within the organ is not usually visible in a laparoscopic view. While MRI enables visualization of the salient structures and cancer foci, its efficacy in LRP is reduced unless it is fused into a stereoscopic view such that homologous structures overlap. Registration of the MRI image and peri-operative ultrasound image using a tracked probe can potentially be exploited to bring the pre-operative information into alignment with the patient coordinate system during the procedure. While doing so, prostate motion needs to be compensated in real-time to synchronize the stereoscopic view with the pre-operative MRI during the prostatectomy procedure. In this study, a point-based stereoscopic tracking technique is investigated to compensate for rigid prostate motion so that the same motion can be applied to the pre-operative images. This method benefits from stereoscopic tracking of the surface markers implanted over the surface of the prostate phantom. The average target registration error using this approach was 3.25+/-1.43mm.

    Upper tract urothelial carcinoma is a relatively uncommon malignancy. The gold standard treatment for this type of neoplasm is an open radical nephroureterectomy with excision of the bladder cuff. This systematic review compares the perioperative and oncologic outcomes for the open surgical method with the alternative surgical management options of laparoscopic nephroureterectomy and robot-assisted nephroureterectomy (RANU). MEDLINE, EMBASE, PubMed, and Cochrane Library databases were searched using a sensitive search strategy. Article inclusion was then assessed by review of abstracts and full papers were read if more detail was required. In all, 50 eligible studies were identified that looked at perioperative and oncologic outcomes. The range for estimated blood loss when examining observational studies was 296 to 696 mL for open nephroureterectomy (ONU), 130 to 479 mL for laparoscopic nephroureterectomy (LNU), and 50 to 248 mL for RANU. The one randomized controlled trial identified reported estimated blood loss and length of stay results in which LNU was shown to be superior to ONU (P ONU with regard to oncologic outcomes. Results show that laparoscopic techniques are superior to ONU in perioperative results, and the longer-term oncologic outcomes look comparable. There is, however, a paucity of quality evidence regarding ONU, LNU, and RANU; data that address RANU outcomes are particularly scarce. As the robotic field within urology advances, it is hoped that this technique will be investigated further using gold standard research methods.

    Full Text Available Study Objective. Prospectively compare outcomes of robotically assisted and laparoscopic hysterectomy in the process of implementing a new robotic program. Design. Prospectively comparative observational nonrandomized study. Design Classification. II-1. Setting. Tertiary caregiver university hospital. Patients. Data collected consecutively 24 months, 34 patients underwent laparoscopic hysterectomy, 25 patients underwent robotic hysterectomy, and 11 patients underwent vaginal hysterectomy at our institution. Interventions. Outcomes of robotically assisted, laparoscopic, and vaginal complex hysterectomies performed by a single surgeon for noncancerous indications. Measurements and Main Results. Operative times were 208.3±59.01 minutes for laparoscopic, 286.2±82.87 minutes for robotic, and 163.5±61.89 minutes for vaginal (<.0001. Estimated blood loss for patients undergoing laparoscopic surgery was 242.7±211.37 cc, 137.4±107.50 cc for robotic surgery, and 243.2±127.52 cc for vaginal surgery (=0.05. The mean length of stay ranged from 1.8 to 2.3 days for the 3 methods. Association was significant for uterine weight (=0.0043 among surgery methods. Conclusion. Robotically assisted hysterectomy is feasible with low morbidity, a shorter hospital stay, and less blood loss. This suggests that robotic assistance facilitates a minimally invasive approach for patients with larger uterine size even during implementing a new robotic program.

    BACKGROUND: An increasing number of women are offered robotic-assisted laparoscopic hysterectomy as treatment for early-stage endometrial cancer in the developed world. OBJECTIVE: The aim of this study was to explore how women diagnosed with early-stage endometrial cancer experienced robotic......-assisted laparoscopic hysterectomy. METHODS: Semistructured interviews were carried out with 12 women, and interview data were analyzed by qualitative content analysis. RESULTS: Four overarching themes emerged: "surgery was a piece of cake," "recovering physically after surgery," "going from being off guard to being...... on guard," and "preparing oneself by seeking information." The women had confidence in the robotic technique and experienced fast recovery after robotic-assisted laparoscopic hysterectomy; however, they had uncertainties and unanswered questions concerning the postoperative course.

    To evaluate the feasibility and usefulness of gasless laparoscopy-assisted distal gastrectomy except when treating obese patients compared with open distal gastrectomy for early cancer. We treated 92 patients with distal gastrectomy for early gastric cancer consecutively. Patients with massive submucosal invasion and/or LN swelling were allocated for the open method, and patients with slightly invasive submucosal cancer were allocated for gasless laparoscopy-assisted surgery. As exceptions we employed open surgery for overweight patients and gasless laparoscopy for elderly and/or feeble patients. We attempted to perform open and laparoscopy-assisted surgery on 52 and 40 patients, respectively. Three cases in the laparoscopy-assisted group were converted to open surgery because of obesity. The age was older and BMI was lower in the laparoscopy-assisted group. In terms of operative time and blood loss as well as postoperative recovery, the results for the laparoscopy-assisted group were superior to those of the open surgery group. There were no cases of cardiopulmonary complications for the laparoscopy-assisted group. Gasless laparoscopy-assisted distal gastrectomy is feasible and useful for early gastric cancer except when treating obese patients.

    Full Text Available Gossypiboma or textiloma are terms commonly used to describe a retained sponge in the body that is composed of sponge invested within a layer of foreign body reaction in the form of an abscess or an aseptic fibrotic reaction. These cases are rarely reported despite an incidence of 1:1,000-1,500 of abdominal or pelvic surgery. We report a patient who presented with an incidental supravesical mass discovered upon work up for frequency and suprapubic pain. He had appendectomy 35 years ago. The mass was excised by robotic-assisted laparoscopic technique. The pathologic evaluation came as gossypiboma.

    2006-01-01

    Full Text Available We report a case of vesicovaginal fistula in 71-year-old lady who had previously undergone a lapascopic assisted nephroureterectomy for transitional cell carcinoma in her right ureter and kidney. The surgery was uncomplicated with no post-operative problems and was discharged on day on seven. She later presented five weeks following the initial operation with signs and symptoms suggestive of a vesicovaginal fistula, which was confirmed on cystogram and flexible cystosopy. She proceeded to have an abdominal (O′Connor′s repair of the fistula together with cystodiathermy for a few superficial bladder recurrences. The area of the fistula (within the bladder was noted to be tumour free. She had an uneventful post-operative recovery and was discharged from hospital on day 11. At six month follow-up, there was another superficial recurrence in the bladder that was resected, with no sign of fistula.

    A 60-year-old male was found to have an 8.0 cm left renal mass and associated renal vein thrombus on computed tomography. The thrombus extended 3 mm beyond the right aortic border to within 1.6 cm of the left border of the inferior vena cava. The patient underwent left nephrectomy with renal vein thrombectomy using a hand-assisted laparoscopic approach. The tumor thrombus was "milked" proximally back into left renal vein, which was then divided with an endovascular stapler. Left renal vein thrombi extending to right margin of the aorta can be managed with hand-assisted laparoscopic approach.

    A 52-year-old man was admitted with an incidentally detected right renal artery aneurysm (RAA). Computed tomographic angiography with three-dimensional reconstruction revealed that the aneurysm was 2.2 cm in diameter and located at the renal hilum. We performed hand-assisted laparoscopic nephrectomy with ex vivo repair of the RAA and auto-transplantation with minimal elongation of Gibson incision. The operation and postoperative course were uneventful. At last follow-up, the patient was alive with a well-functioning auto-transplant. Hand-assisted laparoscopic nephrectomy and auto-transplantation is a useful treatment option for hilar RAA.

    BACKGROUND: The STAR System (Ekymed SpA) is a novel multipurpose sponge developed for conventional manual laparoscopic surgery. MATERIALS AND METHODS: Between December 2012 and December 2014, we successfully used the sponge in ten robot-assisted and ten direct manual laparoscopic operations to achieve haemostasis, for blunt dissections, for atraumatic lifting of solid organs, to check for bile leaks, for cleaning the surgical field thus avoiding frequent use of suction or the application of haemostatic agents. The reason of the insertion (RI), the main use (MU) and any further use (FU), once inserted, were registered for each operation and compared between the two groups. RESULTS: The principal RI was haemostasis for minor bleeding, without differences between the two groups (P = not significant). Regard to MU, in the robotic group cleaning the surgical field was utilised more than laparoscopic group (100% vs. 60%; P = 0.03). About FU, atraumatic solid organs lifting was more frequent during robotically assisted surgery than with laparoscopy (50% vs. 0%; P = 0.01). A statistically more frequent use of the sponge was registered during standard laparoscopy for the blunt dissection (30% vs. 80%; P = 0.03). CONCLUSIONS: The STAR System was beneficial in both approaches, but it imparts added benefit during robotically-assisted laparoscopic surgery organs because of the lack of tactile feedback and because the operating surgeon is remote from the patient, and has to rely on the assisting surgeon in the sterile field for dealing with bleeding episodes, cleansing/mopping the operative field when necessary, who may not be experienced or completely proficient.

    We assessed whether increased BMI has a negative impact in children undergoing robot assisted laparoscopic pyeloplasty (RALP). Records of patients who underwent RALP were retrospectively reviewed and separated into healthy weight, overweight, and obese cohorts based on age-adjusted BMI percentile, and surgical and postsurgical outcomes were evaluated. Of the 103 patients, there were 79 healthy weight and 24 overweight, with 10 of the 24 considered obese (BMIobese cohorts, respectively. Complication rates were similar in regard to minor and major complications. There was no difference in decreased hydronephrosis (92.2%, 89.6%, p=0.440; 88.9%, p=0.730). Four patients (3.4%) required a reoperative procedure (three healthy weight, one overweight; p=NS). Despite the potential difficulties with surgery in overweight patients, our data indicate that robot-assisted laparoscopic pyeloplasty can be performed as safely and effectively in overweight or obese children as in healthy weight children.

    2011-08-01

    Full Text Available Abstract Introduction Bizarre leiomyoma is a rare leiomyoma variant that requires a precise histopathological evaluation. Especially when diagnosed in a younger woman, this tumor leads to challenging treatment issues involving fertility preservation. Owing to the low incidence of bizarre leiomyoma, there is insufficient evidence to support myomectomy alone as an appropriate management option. Also, the impact of bizarre leiomyoma on fertility is not well known. Case presentation A 30-year-old Japanese woman who had never given birth was referred to us because of a uterine tumor with an unusual diagnostic image and was treated by a gasless laparoscopic-assisted excision with a wound retractor. Owing to an unclear margin between her uterine tumor and myometrium, a concomitant excision of adjacent myometrial tissue was required to achieve the maximum resection of her tumor. The histopathological diagnosis was bizarre leiomyoma. Seven months later, she conceived spontaneously and her pregnancy course was uneventful. At 37 weeks of gestation, an elective cesarean section was performed. Although a slight omental adhesion was noted at the postexcisional scar, her uterine wall structure was well preserved and a recurrence of bizarre leiomyoma was not noted. Conclusions A laparoscopic-assisted excision of bizarre leiomyoma is a feasible and minimally invasive conservative measure for a woman who wishes to preserve fertility.

    The objective of this study was to evaluate the short-term outcomes of synchronous hand-assisted laparoscopic (HAL) segmental colorectal resections. The surgical options for synchronous colonic pathology include extensive colonic resection with single anastomosis, multiple synchronous segmental resections with multiple anastomoses, or staged resections. Traditionally, multiple open, synchronous, segmental resections have been performed. There is a lack of data on HAL multiple segmental colorectal resections. A retrospective chart review was compiled on all patients who underwent HAL synchronous segmental colorectal resections by all the colorectal surgeons from our Group during the period of 1999 to 2014. Demographics, operative details, and short-term outcomes are reported. During the period, 9 patients underwent HAL synchronous multiple segmental colorectal resections. There were 5 women and 4 men, with median age of 54 (24-83) years and median BMI of 24 (19.8-38.7) kg/m(2). Two patients were on long-term corticosteroid therapy. The median operative time was 210 (120-330) minutes and median operative blood loss was 200 (75-300) mLs. The median duration for return of bowel function was 2 days and the median length of stay was 3.5 days. We had 2 minor wound infections. There were no deaths. Synchronous segmental colorectal resections with anastomoses using the hand-assisted laparoscopic technique are safe. Early conversion to open and use of stomas are advisable in challenging cases.

    目的:通过对比腹腔镜与开腹远端胃癌D2根治术的疗效及安全性,探讨腹腔镜辅助远端胃癌D2根治术的临床价值。方法221例行远端胃癌D2根治术患者,分为两组。其中腹腔镜组115例,开腹组106例,对两组手术时间、术中出血量、术后排气时间、首次进流质时间、淋巴结清扫数目、术后住院天数、并发症进行比较。结果腹腔镜组手术时间、淋巴结清扫数与开腹组差异无统计学意义(P>0.05),而腹腔镜组术中出血量少,术后肛门排气时间早,首次进流质时间早,术后住院时间短,并发症发生率低(P0.05). However, the laparoscope group had fewer intraoperative bleeding volumes, earlier postoperative anal exhaust time, earlier first time of liquid diet, shorter postoperative hospital stays and lower incidence of complications (P<0.05). Conclusion Laparoscope assisted D2 radical gastrectomy in the treatment of distal gastric cancer has small trauma, few bleeding, quick recovery and less complications. The recent curative effect is similar as that of laparotomy, and the treatment is safe and feasible, and worthy of clinical promotion.

    Osteoarthritis of distal radioulnar joint (DRUJ) leads to chronic wrist pain, weakness of grip strength, and limitation of motion, all of which affect the quality of life of the patient. Over the years, several procedures have been used for the treatment of this condition; however, this condition still remains a therapeutic challenge for the hand surgeons. Many procedures such as Darrach procedure, Bower procedure, Sauvé-Kapandji procedure, and ulnar head replacement have been used. Despite many advances in wrist arthroscopy, arthroscopy has not been used for the treatment of arthritis of the DRUJ. We describe a novel technique of arthroscopically assisted Sauvé-Kapandji procedure for the arthritis of the DRUJ. The advantages of this technique are its less invasive nature, preservation of the extensor retinaculum, more anatomical position of the DRUJ, faster rehabilitation, and a better cosmesis.

    Rapid implementation of robotic transabdominal surgery has resulted in the need for re-evaluation of the most suitable form of anaesthesia. The overall objective of anaesthesia is to minimize perioperative risk and discomfort for patients both during and after surgery. Anaesthesia for patients undergoing robotic assisted surgery is different from anaesthesia for patients undergoing open or laparoscopic surgery; new anaesthetic concerns accompany robotic assisted surgery. To assess outcomes related to the choice of total intravenous anaesthesia (TIVA) or inhalational anaesthesia for adults undergoing transabdominal robotic assisted laparoscopic gynaecological, urological or gastroenterological surgery. We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2016 Issue 5), Ovid MEDLINE (1946 to May 2016), Embase via OvidSP (1982 to May 2016), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) via EBSCOhost (1982 to May 2016) and the Institute for Scientific Information (ISI) Web of Science (1956 to May 2016). We also searched the International Standard Randomized Controlled Trial Number (ISRCTN) Registry and Clinical trials gov for ongoing trials (May 2016). We searched for randomized controlled trials (RCTs) including adults, aged 18 years and older, of both genders, treated with transabdominal robotic assisted laparoscopic gynaecological, urological or gastroenterological surgery and focusing on outcomes of TIVA or inhalational anaesthesia. We used standard methodological procedures of Cochrane. Study findings were not suitable for meta-analysis. We included three single-centre, two-arm RCTs involving 170 participants. We found one ongoing trial. All included participants were male and were undergoing radical robotic assisted laparoscopic radical prostatectomy (RALRP). The men were between 50 and 75 years of age and met criteria for American Society of Anesthesiologists physical classification scores (ASA) I, ll and III.We found

    To study the impact of obesity on the short-term outcomes after laparoscopic-assisted radical gastrectomy. A total of 531 gastric cancer patients underwent radical resection at the Fujian Medical University Union Hospital between May 2007 and June 2010. There were 83 patients with BMI ≥ 25 kg/m(2) (obese group) and 448 patients with BMIobese group). Intraoperative and postoperative parameters, and short-term survival rates between the two groups were compared. There was no significant difference between obese and non-obese patients in terms of conversion rate (2.4% vs. 1.8%, P>0.05). The operative time in obese group was (224.7 ± 57.3) min, which was significantly longer than that in non-obese group [(210.0 ± 57.9) min, Pobese and non-obese groups in terms of blood loss, blood transfusion rate, elevated leukocyte and granulocyte count on the first postoperative day, time to temperature recovery, first flatus, and postoperative hospital stays(P>0.05). The mean number of retrieved lymph nodes in obese group was (24.8 ± 8.4), and was significantly less than that of non-obese group[(29.9 ± 10.2), Pobese and non-obese groups in postoperative complication rate (16.8% vs. 10.2%, P>0.05), postoperative mortality(1.2% vs. 0.4%, P>0.05), and 3-year overall survival (68.8% vs. 74.0%, P>0.05). Obesity is associated with prolonged operative time for laparoscopic radical gastrectomy. However, the short-term outcomes after the laparoscopic radical gastrectomy is not influenced by obesity.

    Despite advances in instruments and techniques in laparoscopic surgery, one thing remains uncomfortable: the camera assistance. The aim of this study was to investigate the benefit of a joystick-guided camera holder (SoloAssist®, Aktormed, Barbing, Germany) for laparoscopic surgery and to compare the robotic assistance to human assistance. 1033 consecutive laparoscopic procedures were performed assisted by the SoloAssist®. Failures and aborts were documented and nine surgeons were interviewed by questionnaire regarding their experiences. In 71 of 1033 procedures, robotic assistance was aborted and the procedure was continued manually, mostly because of frequent changes of position, narrow spaces, and adverse angular degrees. One case of short circuit was reported. Emergency stop was necessary in three cases due to uncontrolled movement into the abdominal cavity. Eight of nine surgeons prefer robotic to human assistance, mostly because of a steady image and self-control. The SoloAssist® robot is a reliable system for laparoscopic procedures. Emergency shutdown was necessary in only three cases. Some minor weak spots could have been identified. Most surgeons prefer robotic assistance to human assistance. We feel that the SoloAssist® makes standard laparoscopic surgery more comfortable and further development is desirable, but it cannot fully replace a human assistant.

    Robot-assisted laparoscopic augmentation ileocystoplasty with Mitrofanoff appendicovesicostomy (RALIMA) may protect the upper urinary tract and reestablish continence in patients with refractory neurogenic bladder. Robotic assistance can provide the benefits of minimally invasive surgery without the steep learning curve of pure laparoscopy. To highlight the interim outcomes of RALIMA with salient tips and technical modifications through comparison with patients undergoing open augmentation ileocystoplasty (OAI). A retrospective chart review of 17 patients undergoing robot-assisted laparoscopic augmentation ileocystoplasty (RALI) and 13 patients undergoing OAI by a single surgeon at an academic center from 2008 to 2012 (OAI) or 2014 (RALI). RALI and all concomitant procedures were performed completely intracorporeally using the da Vinci surgical system (Intuitive Surgical, Inc., Sunnyvale, CA, USA). Outcomes of interest included change in bladder capacity, operative time, pain medication use, hospitalization time, and perioperative complication rates. Of 17 patients selected, 15 successfully underwent RALI. Overall, 11, 6, and 4 patients had a concomitant Mitrofanoff appendicovesicostomy, antegrade colonic enema channel, and bladder neck closure, respectively. The median operative time was significantly longer in RALI (623 vs 287 min; p8 d; p=0.01). The postoperative percentage increase in bladder capacity, narcotic use, and complication rates did not differ between RALI and OAI. Limitations include the retrospective study design and the small cohort of patients. RALI appears to offer functional outcomes similar to OAI. Although it is a significantly longer procedure, it may decrease LOS and avoid epidural use. Further refinements may reduce operative time. In this report, we examined outcomes after robotic bladder augmentation surgery in children. We found that the robotic approach may eliminate epidural analgesia use and decrease hospitalization time after surgery

    To compare surgical outcomes between robot-assisted laparoscopic partial nephrectomy and open partial nephrectomy in patients with chronic kidney disease. Of 550 patients who underwent partial nephrectomy between 2012 and 2015, 163 patients with T1-2 renal tumors who had an estimated glomerular filtration rate between 30 and 60 mL/min/1.73 m(2) , and underwent robot-assisted laparoscopic partial nephrectomy or open partial nephrectomy were retrospectively analyzed. To minimize selection bias between the two surgical methods, patient variables were adjusted by 1:1 propensity score matching. The present study included 75 patients undergoing robot-assisted laparoscopic partial nephrectomy and 88 undergoing open partial nephrectomy. After propensity score matching, 40 patients were included in each operative group. The mean preoperative estimated glomerular filtration rate was 49 mL/min/1.73 m(2) . The mean ischemia time was 21 min in robot-assisted laparoscopic partial nephrectomy (warm ischemia) and 35 min in open partial nephrectomy (cold ischemia). Preservation of the estimated glomerular filtration rate 3-6 months postoperatively was not significantly different between robot-assisted laparoscopic partial nephrectomy and open partial nephrectomy (92% vs 91%, P = 0.9348). Estimated blood loss was significantly lower in the robot-assisted laparoscopic partial nephrectomy group than in the open partial nephrectomy group (104 vs 185 mL, P = 0.0025). The postoperative length of hospital stay was shorter in the robot-assisted laparoscopic partial nephrectomy group than in the open partial nephrectomy group (P robot-assisted laparoscopic partial nephrectomy and open partial nephrectomy provide similar outcomes in terms of functional preservation and perioperative complications among patients with chronic kidney disease. However, a lower estimated blood loss and shorter postoperative length of hospital stay can be obtained with robot-assisted laparoscopic partial

    Full Text Available Purpose: One of the major advantages for patients undergoing minimally invasive surgery as compared to an open surgical procedure is the improved recovery profile and decreased opioid requirements in the perioperative period. There are no definitive studies comparing the analgesic requirements in patients undergoing two different types of minimally invasive procedure. This study retrospectively compares the perioperative analgesic requirements in severely obese adolescents and young adults undergoing laparoscopic versus robotic-assisted, laparoscopic gastric sleeve resection. Materials and Methods: With Institutional Review Board approval, the medication administration records of all severely obese patients who underwent gastric sleeve resection were retrospectively reviewed. Intra-operative analgesic and adjuvant medications administered, postoperative analgesic requirements, and visual analog pain scores were compared between those undergoing a laparoscopic procedure versus a robotic-assisted procedure. Results: This study cohort included a total of 28 patients who underwent gastric sleeve resection surgery with 14 patients in the laparoscopic group and 14 patients in the robotic-assisted group. Intra-operative adjuvant administration of both intravenous acetaminophen and ketorolac was similar in both groups. Patients in the robotic-assisted group required significantly less opioid during the intra-operative period as compared to patients in the laparoscopic group (0.15 ± 0.08 mg/kg vs. 0.19 ± 0.06 mg/kg morphine, P = 0.024. Cumulative opioid requirements for the first 72 postoperative h were similar in both the groups (0.64 ± 0.25 vs. 0.68 ± 0.27 mg/kg morphine, P = NS. No difference was noted in the postoperative pain scores. Conclusion: Although intraoperative opioid administration was lower in the robotic-assisted group, the postoperative opioid requirements, and the postoperative pain scores were similar in both groups.

    To describe patient characteristics and perioperative outcomes among women undergoing roboticassisted laparoscopic hysterectomy and to evaluate the characteristics of nonobese, obese, and morbidly obese patients. A retrospective review was conducted of 442 cases of women who underwent robotic-assisted laparoscopic hysterectomy for benign and malignant conditions over a 4-y period at an academic and community teaching hospital. Patient demographics, surgical indications, operative outcomes, and complications were evaluated for patients with a body mass index (BMI) obese or morbidly obese, with a BMI of ≥30 kg/m(2). Overall, the median estimated blood loss was 100 mL (range, 10 to 800), the operative time was 135 min (range, 40 to 436), and the length of stay was 1 d (range, 0 to 22). These did not differ significantly by BMI group. Overall, 11.9% of patients experienced complications (7.9% minor, 4.1% major), and this did not differ significantly across BMI groups. Robotic hysterectomy can be performed safely in obese and morbidly obese patients, with surgical outcomes and complications similar to those in nonobese patients.

    Colonic lipomata are rare and mostly asymptomatic lesions; but as they become larger they may produce abdominal pain, constipation, diarrhea, hemorrhage, and intussusception. We report the case of a 75-year-old man who suffered from nonspecific recurrent abdominal pain in the left upper and lower quadrants and had variable episodes of diarrhea and constipation of 4 weeks' duration. During colonoscopy, a giant intraluminal polyp was diagnosed at 35 cm. Abdominal helical computed tomography (CT) revealed a constipating colonic tumor with a diameter of >or=50 mm and density values equal to fat. During laparoscopic surgery in the lithotomy position, the sigmoid and the descending colon were mobilized using a Harmonic scalpel. The origin of the polyp was localized precisely under colonoscopic guidance. The former 12-mm incision in the left lower quadrant was expanded to approximately 70 mm for extracorporal tumor resection. The left and sigmoid colon resections were carried out, and the polyp was removed by full-wall excision. After closure with a single-layer suture, the colon was pushed back into the peritoneal cavity. The patient had an uneventful recovery and was discharged 10 days postoperatively. Histology confirmed a benign lipoma of the descending colon. Laparoscopic-assisted resection under endoscopic guidance proved to be suitable for the removal of large colonic polyps without complications.

    Here we report a combined laparoscopic abdominoperineal resection and robotic-assisted prostatectomy. A 74-year-old man was diagnosed with T4b low rectal and prostate cancer. The operation was performed after neoadjuvant chemotherapy for the rectal cancer. The procedure used eight ports in total, five for laparoscopic abdominoperineal resection and six for robotic-assisted prostatectomy. First, laparoscopic total mesorectal excision including division of the inferior mesenteric artery was performed, and then, robotic dissection of the prostate was performed. The en bloc specimen was removed through the perineal wound. Then, robotic urethrovesical anastomosis was performed. An extraperitoneal end colostomy was created to finish the operation. The operating time was 545 min, and blood loss was 170 mL. The postoperative course was uneventful, and the patient discharged on postoperative day 17. The combined laparoscopic abdominoperineal resection and robotic-assisted prostatectomy were performed safely without any additional technical difficulty, as both procedures shared port settings and patient positions.

    To evaluate the feasibility and short-term outcome of hand-assisted laparoscopic colectomy (HALC) for the treatment of colovesical fistula complicating diverticulitis, we reviewed the files of all 34 patients who underwent surgery for diverticular colovesical fistula in 1999 to 2010 at a major tertiary medical center. Twenty-one were treated with HALC and 13 with open colectomy. There were no differences in demographic parameters among the groups. HALC and open colectomy had similar operating time. HALC was associated with a significantly shorter hospital stay compared with open colectomy (5 vs. 8 d, P=0.001). HALC proved to be technically feasible and safe in this setting. It provided benefits of tactile feedback and manual manipulation as in open colectomy while maintaining the advantages of a minimal invasive approach.

    Full Text Available Total restorative proctocolectomy with ileal pouch-anal anastomosis (RP/IPAA has become the standard of care for the surgical treatment of ulcerative colitis. Despite its correlation with an excellent quality of life and favorable long-term outcomes, RP/IPAA has been associated with several complications. Prolapse of the ileoanal pouch is a rare and debilitating complication that should be considered in the differential diagnosis of pouch failure. Limited data exist regarding the prevalence and treatment of pouch prolapse. We present the case of a recurrent J-pouch prolapse treated with a novel minimally invasive “salvage” approach involving a robotic-assisted laparoscopic rectopexy with mesh.

    The aim of this study was to compare outcomes between laparoscopy-assisted distal gastrectomy (LADG) and open distal gastrectomy (ODG) in obese and non-obese patients. Subjects comprised 248 consecutive patients who underwent distal gastrectomy for gastric cancer between January 1999 and December 2005. Patients with body mass index (BMI) > or = 25 kg/m2 were defined as obese, and patients with BMI obese. Parameters analyzed included patients characteristics, tumor characteristics, operative details, postoperative outcomes, and prognosis. For LADG, 35 patients were considered obese, and 106 patients were non-obese. For ODG, 25 patients were considered obese, and 82 patients were non-obese. Mean operative times in each procedure were significantly longer for the obese group than for the non-obese group (ODG: 241.4 min vs. 199.5 min, p obese group than for the non-obese group in ODG (300 ml vs. 400 ml, p = 0.024), but no significant differences were observed between obese and non-obese groups for LADG. Incidence of major postoperative complications, number of retrieved lymph nodes, and disease-free survival rates were similar in obese and non-obese groups for each procedure. Our analysis revealed that LADG can be safely performed in obese patients, with complication rates and operation outcomes similar to those for non-obese patients.

    We report the natural history of voiding function in men with clinically localized prostate cancer after robot-assisted laparoscopic radical prostatectomy (RLRP), describing the trend of functional recovery, which is currently not well described using the robot-assisted laparoscopic approach. We determined the impact on voiding function by prospectively evaluating 100 consecutive men who underwent RLRP between May 2005 and December 2006 and compared their reported International Prostate Symptom Score (IPSS) and Quality of Life (QOL) scores at 3, 6, and 12 months with preoperative scores after surgery. Patients with preoperative IPSS of 0-7 and 8-35 were defined as having mild lower urinary tract symptoms (LUTS) and moderate to severe LUTS, respectively. Continence was achieved in 82%, 87%, and 91% of men at 3, 6, and 12 months after RLRP, respectively. There were statistically and clinically significant improvements in both IPSS and QOL preoperative scores at all studied time points for patients with moderate to severe preexisting LUTS. The mean IPSS scores for these patients preoperatively and at 3, 6, and 12 months after surgery were 14.1, 5.2, 3.0, and 2.9, respectively and the corresponding mean QOL scores were 3.4, 2.1, 1.6, and 1.6, respectively. Patients with mild preexisting LUTS showed no statistically significant improvement in IPSS at 3 and 6 months after surgery but significant improvement was found at 1 year (P = 0.04). Good continence recovery is expected in most patients undergoing RLRP. Patients with moderate to severe preexisting LUTS can expect early and clinically significant symptom and QOL improvements after RLRP. Patients with mild preexisting LUTS show significant symptom improvement at 1 year. Copyright © 2011 Elsevier Inc. All rights reserved.

    To describe our technique for the repair of a cesarean section uterine scar defect after removal of an ectopic pregnancy from the scar in a patient desiring future pregnancies. Step-by-step explanation of the procedure using video (Canadian Task Force classification III). Uterine scar dehiscence/defect is a known complications of multiple cesarean deliveries that can result in abnormal bleeding, infertility, and cesarean scar ectopic pregnancy. With the increasing number of cesarean sections performed in the United States, the prevalence of this complication is rising. Nonetheless, there currently are no standardized surgical treatment guidelines available to manage this pathology through a minimally invasive approach. In this video, we describe our technique for the surgical management of a symptomatic cesarean section scar defect. We performed a robotic-assisted laparoscopic repair of this defect in a 40-year-old G4P3013 with a recent cesarean section scar ectopic pregnancy managed by endometrial curettage, with subsequent persistent abnormal vaginal bleeding. A repeat ultrasound revealed a low uterine segment defect consistent with dehiscence. She was referred to us because she desired a conservative treatment given her desire for future pregnancies. The defect was localized by hysteroscopy and laparoscopy after developing the bladder flap. The scar tissue around the defect was resected, and the freshened edges of the defect were closed using delayed absorbable suture. Chromopertubation confirmed the watertightness of the repair. Postoperatively, the patient had regular normal periods, and her hysterosalpingogram didn't show any uterine defect. Robotic-assisted laparoscopic repair of cesarean section scar defect is a feasible and safe procedure when done with respect to anatomy and following sound surgical technique. With the increasing number of cesarean sections, gynecologists will be dealing with this pathology more frequently, and need to become more

    The aim of this study was to describe the surgical technique and report the safety and feasibility of robotic-assisted laparoscopic sacrohysteropexy, a uterine sparing procedure to correct pelvic organ prolapse (POP). Hysterectomy at the time of POP surgery has yet to be proven to improve the durability of repair. Nevertheless, the leading indication for hysterectomy in postmenopausal women is POP. We reviewed the medical records of a consecutive case series of uterine sparing prolapse repair procedures from 2005 to 2011. Fifteen women were identified. Procedures utilized a type I polypropylene mesh securing the posterior uterocervical junction to the sacral promontory. This was later modified to utilize a Y-shaped strip that was inserted through the broad ligaments to include the anterior uterocervical junction. Objective success was defined as Baden Walker grade 0 uterine prolapse and subjective success was defined as no complaint of vaginal bulge or pressure. The mean age of women was 51.8 years (28-64 years). No intraoperative complications were noted. The mean operating time was 159.4 minutes (130-201 minutes) and mean estimated blood loss was 35 mL (0-100 mL). The mean length of stay was 1.6 days (1-4 days) and mean length of follow-up was 10.8 months. Uterine prolapse improved in all 15 patients. Objective success was 93% (14/15) and subjective success was 80% (12/15). Robotic-assisted laparoscopic sacrohysteropexy was found to be a safe and feasible surgical treatment option for POP patients who desire uterine preservation.

    Laparoscopic colposacropexy has become a substitute for open surgery in the treatment of pelvic organ prolapse. In the same way, robotic assisted surgery is a new step in the evolution of the procedure. In this paper we intend to show our surgical technique and preliminary results. From November 2006 to date, 10 patients have undergone this procedure at the Hospital Clinico San Carlos. The main indication for the operation was existence of symptomatic pelvic prolapse. Both patients with or without hysterectomy have been operated, without making significant differences between them. Preoperative evaluation workout included: cystogram, urinary tract ultrasound and urodynamics in all cases; urinary tract MRI was performed only in selected cases. All patients underwent surgery under general anesthesia, with at least three robotic trocars (8 mm) and one conventional trocar for the assistant; 2 accessory trocars were necessary in some cases, mainly at the beginning of the series. Most procedures in our series were associated with a transobturator suburethral sling for the treatment of stress urinary incontinence or prevention of its appearance after prolapse repair. Our results are comparable to those reported in other larger series in terms of operative time, hospital stay and early or late complications. Pending an evaluation on the long term with larger series, we can include robot assisted colposacropexy among the therapeutic options for symptomatic pelvic floor prolapse repair.

    AIM: To evaluate the nature of the "learning curve" for laparoscopy-assisted distal gastrectomy (LADG) with systemic lymphadenectomy for early gastric cancer. METHODS: The data of 90 consecutive patients with early gastric cancer who underwent LADG with systemic lymphadenectomy between April 2003 and November 2004 were reviewed. The 90 patients were divided into 9 sequential groups of 10 cases in each group and the average operative time of these 9 groups were determined. Other learning indicators, such as transfusion requirements, conversion rates to open surgery, postoperative complication, time to first flatus, and postoperative hospital stay, were evaluated. RESULTS: After the first 10 LADGs, the operative time reached its first plateau (230-240 min/operation) and then reached a second plateau (<200 min/operation) for the final 30 cases. Although a significant improvement in the operative time was noted after the first 50 cases, there were no significant differences in transfusion requirements, conversion rates to open surgery, postoperative complications, time to first flatus, or postoperative hospital stay between the groups. CONCLUSION: Based on operative time analysis, this study show that experience of 50 cases of LADG with systemic lymphadenectomy for early gastric cancer is required to achieve optimum proficiency.

    The objective of the study was to describe the feasibility of a glove port technique for laparoscopic-assisted surgical treatment of canine pyometra. In this retrospective case series, a total of 10 female dogs (median age 7 years, range 5.5-10.5 years; median weight 37.0 kg, range 12.9-64.0 kg) with pyometra were included. A multiaccess port was created from a surgical glove attached to an Alexis wound retractor and placed in the ventral midline between the middle and caudal third of the distance between umbilicus and pubic rim. A vessel sealing device was used for transection of the ovarian pedicle. The port size was selected on the basis of maximum uterine diameter determined by ultrasound. Median incision length was 5.0 cm (range 3.1-7.7 cm) for a maximum uterine diameter of 4.0 cm (range 2.0-7.0 cm). Median surgical time was 57 minutes (range 48-65 minutes). No case had to be converted to open celiotomy. Complications included one case of minor, self-limiting splenic trauma by the endoscope. In eight dogs, the distended uterine horns endangered safe access to the ovarian pedicle, and the vessel sealing device was inserted through a second cannula placed periumbilically. Extension of the original incision was necessary to exteriorize organs in two dogs. All dogs recovered quickly and were discharged either on the day of surgery or 1 day thereafter. In conclusion, a surgical glove port technique in combination with an Alexis wound retractor is feasible for surgical laparoscopic treatment of canine pyometra up to a diameter of 7 cm.

    Full Text Available Robot-assisted radical cystectomy with intracorporeal urinary diversion (RARC-ICUD has only recently been explored as a viable surgical option for patients with muscle-invasive bladder cancer seeking satisfactory oncologic control while benefiting from minimally invasive surgical techniques. Inspired by earlier open and laparoscopic work, initial descriptions of RARC-ICUD were published in 2003, and have since been followed by multiple larger case series which have suggested promising outcomes for our patients. However, the rate of adoption has remained relatively slow when compared to other robot-assisted procedures such as the radical prostatectomy, likely owing to longer operative times, operative complexity, costs, and uncertainty regarding oncologic efficacy. The operative technique for RARC-ICUD has evolved over the past decade and several high-volume centers have shared tips to improve efficiency and make the operation possible for a growing number of urologists. Though there are still questions regarding economic costs, effectiveness, and generalizability of outcomes reported in published data, a growing dataset has brought us ever closer to the answers. Here, we present our current operative technique for RARC-ICUD and discuss the state of the literature so that the urologist may hold an informed discussion with his or her patients.

    2010-12-01

    Full Text Available Abstract Background Malunion is the most common complication of distal radius fracture. It has previously been demonstrated that there is a correlation between the quality of anatomical correction and overall wrist function. However, surgical correction can be difficult because of the often complex anatomy associated with this condition. Computer assisted surgical planning, combined with patient-specific surgical guides, has the potential to improve pre-operative understanding of patient anatomy as well as intra-operative accuracy. For patients with malunion of the distal radius fracture, this technology could significantly improve clinical outcomes that largely depend on the quality of restoration of normal anatomy. Therefore, the objective of this study is to compare patient outcomes after corrective osteotomy for distal radius malunion with and without preoperative computer-assisted planning and peri-operative patient-specific surgical guides. Methods/Design This study is a multi-center randomized controlled trial of conventional planning versus computer-assisted planning for surgical correction of distal radius malunion. Adult patients with extra-articular malunion of the distal radius will be invited to enroll in our study. After providing informed consent, subjects will be randomized to two groups: one group will receive corrective surgery with conventional preoperative planning, while the other will receive corrective surgery with computer-assisted pre-operative planning and peri-operative patient specific surgical guides. In the computer-assisted planning group, a CT scan of the affected forearm as well as the normal, contralateral forearm will be obtained. The images will be used to construct a 3D anatomical model of the defect and patient-specific surgical guides will be manufactured. Outcome will be measured by DASH and PRWE scores, grip strength, radiographic measurements, and patient satisfaction at 3, 6, and 12 months

We hypothesized that a steep Trendelenburg position during RALP, an unusual systemic condition involving a transiently increased IOP, may induce ocular pathology that can be detected by detailed evaluations long after the surgery. This study aims to explore ocular structural and functional parameters in patients before and in the long term after the surgery. Patients and methods: A comparative observational study was performed. A total of 44 eyes of 22 male patients scheduled for RALP at Aichi Medical University from August 2012 to July 2013 were included. Clinical parameters before and after RALP were compared. Peri­operative IOP was measured immediately post-induction of anesthesia in the flat supine position (T1, immediately post-steep Trendelenburg position (T2, and prior to returning to a flat supine position while in a steep Trendelenburg position (T3. The thicknesses of the peripapillary retinal nerve fiber layer, ganglion cell complex (GCC, and central fovea were measured with spectral domain optical coherence tomography. Humphrey perimetry was performed before and at 3 and 6 months after surgery. Results: The average IOPs (mmHg at each stage were T1=10.4, T2=21.7, and T3=29.6, and differed significantly. The mean visual acuity (logarithm of the minimal angle of resolution, IOP, mean deviation, and pattern standard deviation measured by the Humphrey field analyzer showed no statistically significant difference before and after surgery.

    2010-01-01

    Full Text Available There are two approaches to laparoscopic donor nephrectomy: standard laparoscopic donor nephrectomy (LDN and hand-assisted laparoscopic donor nephrectomy (HALDN. In this study we report the operative statistics and donor complications associated with LDN and HALDN from large-center peer-reviewed publications. Methods. We conducted PubMed and Ovid searches to identify LDN and HALDN outcome studies that were published after 2004. Results. There were 37 peer-reviewed studies, each with more than 150 patients. Cumulatively, over 9000 patients were included in this study. LDN donors experienced a higher rate of intraoperative complications than HALDN donors (5.2% versus. 2.0%, <.001. Investigators did not report a significant difference in the rate of major postoperative complications between the two groups (LDN 0.5% versus HALDN 0.7%, =.111. However, conversion to open procedures from vascular injury was reported more frequently in LDN procedures (0.8% versus 0.4%, =.047. Conclusion. At present there is no evidence to support the use of one laparoscopic approach in preference to the other. There are trends in the data suggesting that intraoperative injuries are more common in LDN while minor postoperative complications are more common in HALDN.

    Laparoscopic retroperitoneal lymph node dissection, especially when performed with the da Vinci Surgical System (Intuitive Surgical), has shown excellent cosmetic results with similar oncologic outcomes to those of open surgery. In this study, we present a case of robot-assisted retroperitoneal lymph node dissection performed in an 18-year-old man who was diagnosed with a stage IIIb mixed germ cell tumor and who was initially treated with radical orchiectomy, followed by chemotherapy. This case shows that robot-assisted retroperitoneal lymph node dissection is technically feasible, safe, and cosmetically favorable, even when performed on patients with high-stage disease or after chemotherapy.

    Full Text Available Introduction: Laparoscopic adrenalectomy (LA is now considered the standard for treatment of surgically correctable adrenal disorders. Robotic adrenalectomy has been performed worldwide and has established itself as safe, feasible and effective approach. We hereby present the first study in robotic transperitoneal LA from Indian subcontinent. Materials and Methods: We conducted a retrospective evaluation of 25 patients who had undergone robotic assisted LA at a tertiary health centre by a single surgeon. Demographic, clinical, histopathological and perioperative outcome data were collected and analysed. Results: Mean age of the patients was 45 years (range: 27-65 years. Eleven male and 14 female patients were operated. Mean operative time was 139 min ± 30 min (range: 110-232 min and mean blood loss was 85 ml ± 12 ml (range: 34-313 ml. Mean hospital stay was 2.5 ± 1.05 days (range: 2-6 days. Mean visual analogue scale score was 3.2 (range: 1-6 mean analgesic requirement was 50 mg diclofenac daily (range: 0-150 mg. Histopathological evaluation revealed 11 adenomas, eight phaeochromocytomas, two adrenocortical carcinomas, and four myelolipomas. According to Clavien-Dindo classification, three patients developed Grade I post-operative complications namely hypotension and pleural effusion. Conclusion: Robotic adrenalectomy is safe, technically feasible and comfortable to the surgeon. It is easier to perform with a short learning curve.

    Recently, we have introduced robotic-assisted laparoscopic radical prostatectomy (RALP) in Japan. This article describes the details of a training program to shorten the learning curve in the absence of an urologist with expertise in robotic surgery. Five months after a 2-day training course of robotic surgery, RALP was first performed in Japan, and a total of 15 cases were performed in the subsequent 4 months. Our training program consisted of: (1) image training using surgical operation videos, (2) dry lab training using a sham pelvic cavity model, and (3) intraoperative mentoring. The operative procedure was divided into five consecutive stages, and time required to complete each stage was recorded. Robotic radical prostatectomy was completed in all patients without conversion to open surgery, except for the first patient in whom a restriction to a 2-h operation had been imposed by the ethics committee. The mean console time and the mean intraoperative blood loss (including urine) reduced from 264.2 min and 459.4 ml, respectively, in the first 11 cases, to 151 min and 133.3 ml, respectively, in the last three cases. With direct intraoperative guidance by the mentor during cases 13 and 14, the operation time was reduced at all five stages of the operative procedure. Our training program proved remarkably effective in reducing the learning curve of RALP in Japan, where there is no person with expertise in robotic surgery.

    To describe a technique for treating pyometra in dogs using a 3-portal laparoscopic-assisted ovariohysterectomy (LAOVH) and evaluate outcome. Retrospective case series. Dogs (n = 12). Dogs with open or closed-cervix pyometra with moderately sized (1-4 cm) uterine horn diameters based on preoperative ultrasonography and no evidence of perforation were included in the study. A 3-portal technique for LAOVH was used. A wound retraction device was inserted into the caudal portal after enlargement of the incision to 3-4 cm to simplify removal of the uterus with minimal tension. Twelve dogs (median weight, 23.3 kg; range, 2.1-46.0 kg) met the inclusion criteria. Median uterine diameter was 3.0 cm (range, 1.2-4.0 cm). Median surgical time for LAOVH was 107 minutes (range, 82-120 minutes). Complications included mild hemorrhage from the uterine vessels in 1 dog during uterine removal through the wound retraction device and intra-abdominal uterine rupture in 1 dog which necessitated conversion to an open approach. All dogs recovered from surgery and were discharged. LAOVH can be used for treatment of select cases of canine pyometra. Careful case selection is mandatory to improve success and minimize conversion to an open approach. Gentle handling of the reproductive organs is imperative to avoid iatrogenic uterine rupture. © 2013 by The American College of Veterinary Surgeons.

  2. Comparison of peritoneal free gastric cancer cells' detecting rates between laparoscopically assisted and open radical gastrectomy

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Objective: To compare laparoscopic gastrectomy and conventional surgery on the dissemination and seeding of tumor cells. Methods:Intraoperative peritoneal lavage cytologic examination was performed in 65 patients with gastric cancer, during laparoscopic gastrectomy (n=34) and conventional surgery (n=31). Cytology was examined twice, immediately after opening the peritoneal cavity and just before closing the abdomen. Saline was poured into the peritoneal cavity, and 100 ml fluid was retrieved after irrigation. Laparoscopic instruments were lavaged after surgery with 100 ml saline. Carbon dioxide (CO2) was derived through the trocar side orifice after pneumoperitoneum during laparoscopic gastrectomy and filtered through 100 ml saline. Cytologic examination of the filtrate was performed after the filtration process. Results: The incidence of positive cytology during laparoscopic surgery was 32.26% in the preoperative lavage and 22.58% in the postoperative lavage. The incidence of positive cytology during conventional surgery was 41.18% before lavage and 26.47% after lavage. Only one positive cytology was detected in the CO2 filtrate gas. The incidence of positive cytology in the lavage of the instruments during laparoscopic surgery was 6.45%. Conclusion: During gastric laparoscopic surgery, CO2 pneumoperitoneum does not affect tumor cell dissemination and seeding. In this study, laparoscopic techniques used in gastric cancer surgery were not associated with a higher risk for intraperitoneal dissemination of cancer cells than the conventional surgery.

    To assess the safety and outcomes of vaginally assisted laparoscopic uterine sacropexy (VALUES) as a surgical treatment for stage 3 and 4 uterine prolapse. Seventy consecutive women with stage 3 and 4 uterine prolapse who underwent VALUES over 2-year period were prospectively evaluated. Women filled the Prolapse Quality of Life Questionnaire (P-QOL), and underwent examination using pelvic organ prolapse quantification system (POP-Q) pre- and post-operatively. In addition, patients filled the patient global impression of improvement questionnaire post-operatively. Mesh related complications were evaluated post-operatively. Patients were followed up at 3 and 12 months following surgery. This study reports the 12 months outcomes. Sixty-four women (91.4%) reported cure of their prolapse symptoms. On examination, 67 women (95.7%) had POP-Q stage 0 or 1 uterine support at 12 months. Six women needed further surgical intervention for prolapse (8.5%); three women developed recurrent uterine prolapse and three other women developed symptomatic recurrent anterior vaginal wall prolapse. The total vaginal length was not different between the pre- and post-operative periods. Two patients developed mesh related complications. Significant improvement was noted in prolapse symptoms and quality of life. VALUES is a safe and effective treatment for women with stage 3 and 4 uterine prolapse up to 12 months without the risk of vaginal shortening. Long-term results are needed to fully establish the value of this technique. © 2013 Wiley Periodicals, Inc.

    Full Text Available Introduction. Meckel’s diverticulum (MD is the most common congenital anomaly of the intestine, with an incidence of 2~4%. Of those, only 2% of patients with MD are symptomatic. Torsion of MD is extremely rare, and only a dozen cases have been previously reported. Case Report. The patient was a 49-year-old male who presented to our emergency room with a chief complaint of lower abdominal pain. Computed tomography imaging revealed an irregular polycystic mass connected to the small intestine that measured 7.5 cm in a diameter. A laparoscopic-assisted partial resection of the jejunum was performed. The lesion was found to have caused torsion and was located 130 cm from the ileocecal valve. The specimen was polycystic in appearance and showed communicating links with the submucosal layer of jejunum but not with the lumen. The pathological diagnosis was a torsion of an atypical presentation of MD. Conclusion. This case was different from typical cases of MD in that it was located on significantly oral side and had the appearance of polycystic morphology.

    Two prospective trials have demonstrated prophylactic antimuscarinics following prostatectomy reduce pain from bladder spasms. Our practice adopted the routine administration of prophylactic belladonna and opium (B&O) suppositories to patients undergoing robotic assisted laparoscopic radical prostatectomy (RALP). The aim of this study is to determine if this change in clinical practice was associated with improvement of postoperative outcomes. The medical records of 202 patients that underwent RALP surgery who were or were not administered prophylactic B&O suppositories in the immediate postoperative period were abstracted for duration of anesthesia recovery, pain and analgesic use. Patient and surgical characteristics between groups were similar except B&O group were slightly older (p = 0.04) and administered less opioid analgesics (p = 0.05). There was no difference between groups in the duration of phase I recovery from anesthesia (p = 0.96). Multivariable adjustments for age, body mass index, American Society of Anesthesiologists physical status, and surgical duration were made, and again it was found that suppository administration had no association with phase I recovery times (p = 0.94). The use of antimuscarinic medication for bladder spams in the B&O group was less during phase I recovery (p suppositories at the immediate conclusion of RALP surgery was not associated with improvements of the postoperative course.

    2011-07-01

    Full Text Available Abstract Background Open transthoracic oesophagectomy is the standard treatment for infracarinal resectable oesophageal carcinomas, although it is associated with high mortality and morbidity rates of 2 to 10% and 30 to 50%, respectively, for both the abdominal and thoracic approaches. The worldwide popularity of laparoscopic techniques is based on promising results, including lower postoperative morbidity rates, which are related to the reduced postoperative trauma. We hypothesise that the laparoscopic abdominal approach (laparoscopic gastric mobilisation in oesophageal cancer surgery will decrease the major postoperative complication rate due to the reduced surgical trauma. Methods/Design The MIRO trial is an open, controlled, prospective, randomised multicentre phase III trial. Patients in study arm A will receive laparoscopic-assisted oesophagectomy, i.e., a transthoracic oesophagectomy with two-field lymphadenectomy and laparoscopic gastric mobilisation. Patients in study arm B will receive the same procedure, but with the conventional open abdominal approach. The primary objective of the study is to evaluate the major postoperative 30-day morbidity. Secondary objectives are to assess the overall 30-day morbidity, 30-day mortality, 30-day pulmonary morbidity, disease-free survival, overall survival as well as quality of life and to perform medico-economic analysis. A total of 200 patients will be enrolled, and two safety analyses will be performed using 25 and 50 patients included in arm A. Discussion Postoperative morbidity remains high after oesophageal cancer surgery, especially due to major pulmonary complications, which are responsible for 50% of the postoperative deaths. This study represents the first randomised controlled phase III trial to evaluate the benefits of the minimally invasive approach with respect to the postoperative course and oncological outcomes in oesophageal cancer surgery.

    The purpose of this report is to evaluate our experience with transvaginal application of a laparoscopic bipolar cutting forceps to assist vaginal hysterectomy in extremely obese women with endometrial cancer in whom obesity precluded LAVH/BSO and lymphadenectomy and vaginal obesity limited visualization and exposure. We performed a retrospective review and identified 6 consecutive cases. No cases were excluded. A laparoscopic 33-cm Plasma Kinctic (PK) cutting forceps with a 5-mm diameter was applied transvaginally to coagulate and cut the uterosacral and cardinal ligaments, uterine vasculature, and ovarian ligaments. The uterus was delivered vaginally. Staging lymphadenectomy was not performed. Median age was 51 years, median weight was 405 lbs, and median BMI was 66 kg/m². Five of 6 cases were successfully performed vaginally (83%). Median operative time was 1 hour 10 minutes, median blood loss was 500 mL, and pain was only discomforting. All patients were discharged the day after surgery. There were no complications. At median follow-up of 1 year, all patients were alive with no evidence of disease. It is our opinion that the transvaginal application of a laparoscopic bipolar cutting forceps can successfully assist vaginal hysterectomy in extremely obese endometrial cancer patients who cannot tolerate LAVH/BSO and lymphadenectomy and vaginal obesity limits visualization and exposure.

    Gallstone ileus is an uncommon complication of cholelithiasis. Most patients affected by gallstone ileus are elderly and have multiple comorbidities. Symptoms are vague and insidious, which may delay the correct diagnosis for days. Here we are reporting an uncommon complication of gallstone ileus. We report on a 70-year-old man with small bowel obstruction at the jejunum due to an impacted stone, which led to necrosis and perforation of the proximal bowel wall. Laparoscope-assisted small bowel resection with enterolithotomy was used to successfully treat the patient's perforation and obstruction. His recovery was uneventful. Gallstone ileus commonly presents with bowel obstruction, but intestinal perforation occurs very rarely. A laparoscopic approach can provide both diagnostic and therapeutic roles in management.

    Laparoscopic-assisted ventral hernia repair (LAVHR) with mesh is well established as the preferred technique for hernia repair. We sought to determine whether primary fascial closure and/or overlap of the mesh reduced recurrence and/or complications. We conducted a retrospective review on 57 LAVHR patients using polyester composite mesh between August 2010 and July 2013. They were divided into mesh-only (nonclosure) and primary fascial closure with mesh (closure) groups. Patient demographics, prior surgical history, mesh overlap, complications, and recurrence rates were compared. Thirty-nine (68%) of 57 patients were in the closure group and 18 (32%) in the nonclosure group. Mean defect sizes were 15.5 and 22.5 cm(2), respectively. Participants were followed for a mean of 1.3 years [standard deviation (SD) = 0.7]. Recurrence rates were 2/39 (5.1%) in the closure group and 1/18 (5.6%) in the nonclosure group (P = 0.947). There were no major postoperative complications in the nonclosure group. The closure group experienced four (10.3%) complications. This was not a statistically significant difference (P = 0.159). The median mesh-to-hernia ratio for all repairs was 15.2 (surface area) and 3.9 (diameter). Median length of stay was 14.5 hours (1.7-99.3) for patients with nonclosure and 11.9 hours (6.9-90.3 hours) for patients with closure (P = 0.625). In conclusion, this is one of the largest series of LAVHR exclusively using polyester dual-sided mesh. Our recurrence rate was about 5 per cent. Significant mesh overlap is needed to achieve such low recurrence rates. Primary closure of hernias seems less important than adequate mesh overlap in preventing recurrence after LAVHR.

    Background and Objectives: To determine prostate cancer biochemical recurrence rates with respect to surgical margin (SM) status for patients undergoing robotic-assisted laparoscopic radical prostatectomy (RALP). Methods: IRB-approved radical prostatectomy database was queried. Patients were stratified as low, intermediate, and high risk according to D’Amico's risk classification. Postoperative prostate-specific antigen (PSA) values were obtained every 3 mo for the first year, then biannually and annually thereafter. Biochemical recurrence was defined as ≥0.2ng/mL. Patients receiving adjuvant or salvage treatment were included. Positive surgical margin was defined as presence of cancer cells at inked resection margin in the final specimen. Margin presence (negative/positive), margin multiplicity (single/multiple), and margin length (≤3mm focal and >3mm extensive) were noted. Kaplan-Meier curves of biochemical recurrence-free survival (BRFS) as a function of SM were generated. Forward stepwise multivariate Cox regression was performed, with preoperative PSA, Gleason score, pathologic stage, prostate gland weight, and SM as covariates. Results: At our institution, 1437 patients underwent RALP (2003-2009). Of these, 1159 had sufficient data and were included in our analysis. Mean follow-up was 16 mo. Kaplan-Meier curves demonstrated significant increase in BRFS in low-risk and intermediate-risk groups with negative SM. Overall BRFS at 5 y was 72%. Gleason score, pathologic stage, and SM status were significant prognostic factors in multivariate analysis. Conclusions: Negative surgical margins resulted in lower biochemical recurrence rates for low-risk and intermediate-risk groups. Multifocal and longer positive margins were associated with higher biochemical recurrence rates compared with unifocal and shorter positive margins. Documenting biochemical recurrence rates for RALP is important, because this treatment for localized prostate cancer is validated. PMID

    Full Text Available OBJECTIVE: We report our initial experience with 62 patients undergoing robotic-assisted laparoscopic prostatectomy (RALP, focusing on the primary parameter of positive surgical margins. The authors demonstrate that excellent oncologic outcomes can be attained with a less steep learning curve than previously hypothesized. MATERIALS AND METHODS: The first 62 patients undergoing RALP by a single physician (DPD at our institution between November 2005 and August 2007 were retrospectively assessed. Surgical pathology records were reviewed for Gleason score, pathologic tumor stage, nodal status, location of prostate cancer within the specimen, extracapsular extension, surgical margin status, presence of perineural invasion, tumor volume, and weight of the surgical specimen. Margin status was determined using surgical specimens only, and not intraoperative frozen sections. All cases in this series were completed using the four-arm da Vinci Robotic System (Intuitive Surgical, Sunnyvale, California. RESULTS: Sixty-one patients had prostate cancer on their final surgical pathology specimens. Pathologic stage T2 and stage T3 patients were 88.7% and 9.7% of all cases, respectively. The pathologic Gleason score was 7 or greater in 62.3%. Our overall positive surgical margin rate was 3.3%. Patients with pathologic T2 and T3 disease had a positive surgical margin rate of 1.8% and 16.7%, respectively. CONCLUSIONS: Our study suggests that RALP can have equal if not better pathologic outcomes compared to open radical prostatectomy even during the initial series of cases. We argue that the learning curve for RALP is shorter than previously thought with respect to oncologic outcomes, and concerns asserting that lack of tactile feedback leads to poor oncologic outcomes are unfounded.

    Purpose To demonstrate the feasibility, safety, and technical strategies of hand-assisted laparoscopic complete mesocolic excision (HAL-CME) and to compare oncological outcomes between HAL-CME and the open approach (O-CME) for right colon cancers. Methods Patients who were scheduled to undergo a right hemicolectomy were divided into HAL-CME and O-CME groups. Measured outcomes included demographic variables, perioperative parameters, and follow-up data. Demographic variables included age, sex distribution, body mass index (BMI), American Society of Anesthesiologists (ASA) physical status classification, previous abdominal surgery, tumor localization, and potential comorbidities. Perioperative parameters included incision length, operative time, blood loss, conversion rate, postoperative pain score, postoperative first passage of flatus, duration of hospital stay, total cost, number of lymph nodes retrieved, TNM classification, and postoperative complications. Follow-up data included follow-up time, use of chemotherapy, local recurrence rate, distant metastasis rate, and short-term survival rate. Results In total, 150 patients (HAL-CME, 78; O-CME, 72) were included. The groups were similar in age, sex distribution, BMI, ASA classification, history of previous abdominal surgeries, tumor localization, and potential comorbidities. Patients in the HAL-CME group had shorter incision lengths, longer operative times, less operative blood loss, lower pain scores, earlier first passage of flatus, shorter hospital stay, higher total costs, similar numbers of lymph nodes retrieved, similar TNM classifications, and a comparable incidence of postoperative complications. The 2 groups were also similar in local recurrence rate, distant metastasis rate, and short-term survival rate. Conclusion The results demonstrate that the HAL-CME procedure is a safe, valid, and feasible surgical method for right hemicolon cancers. PMID:28203556

    Measuring quality of life of women with disorders of the pelvic floor is crucial when evaluating a therapy. The aim of this study is to profile health related quality of life of women with pelvic organ prolapse who are treated with robot assisted laparoscopic sacrohysteropexy (RALS). We also compare the operative characteristics and learning curve in this study with the current literature and describe the surgical technique. A prospective cohort study in a teaching hospital in The Netherlands. Fifty women with uterovaginal prolapse were treated with RALS. This study presents the largest cohort in Europe treated by RALS to date. Quality of life was assessed pre- and post-operatively using the UDI/IIQ validated self-questionnaire designed for Dutch-speaking patients. Clinical and operative data were prospectively collected up to 29 months. RALS was performed with preservation of the uterus. Statistical analysis of categorical data was performed with the paired T-test. Descriptive statistics were computed with the use of standard methods for means, median and proportions. Before operation, overall wellbeing was scored at 67.7% and after surgery this improved to 82.1% (p=0.03). Feelings of nervousness, frustration and embarrassment reduced significantly. Sexual functioning improved, but not significantly. The mean operative time was 223 (103-340) min. Operative time decreased significantly with gained experience and became comparable to the operative time for abdominal sacrocolpopexy and classic laparoscopy. Average blood loss was less than 50 ml and patients had a mean hospital stay of 2 days. Of all women, 95.2% were very satisfied with the result after RALS. Health related quality of life improves significantly after RALS. There are high rates of patient satisfaction. RALS proves to be a safe and effective treatment of pelvic organ prolapse. Operative time is comparable to abdominal sacrocolpopexy and classic laparoscopy in the current literature. Copyright © 2012

    Robotic-assisted laparoscopic prostatectomy (RALP) is usually performed in steep Trendelenburg position, which can be associated with cardiac impairment due to positioning and capnoperitoneum. This study investigated haemodynamic consequences and cardiac function in this type of surgery and evaluated the hypothesis that steep Trendelenburg position and capnoperitoneum results in haemodynamic and ventricular impairment. 10 patients (ASA I-III) scheduled for RALP in steep Trendelenburg position with capnoperitoneum were prospectively studied. Heart rate (HR), mean arterial pressure (MAP) and central venous pressure (CVP) were recorded. Stroke volume variation (SVV) and cardiac output (CO) were measured using pulse-contour analysis. Further, cardiac function was assessed using trans-oesophageal echocardiography before positioning (T1) and 10 min (T2) and 60 min (T3) after implementation of steep Trendelenburg position and capnoperitoneum. HR did not change statistically. MAP (T1, 69.7 ± 1.55; T2, 82.9 ± 3.05; T3, 79.4 ± 2.18 mmHg), CVP (T1, 7.7 ± 1.3; T2, 17.3 ± 2.01; T3, 16.9 ± 1.66 mmHg) and CO (T1, 4.0 ± 0.15; T2, 4.9 ± 0.26; T3, 4.9 ± 0.36 l/min) increased significantly at T2 and T3. Echocardiography showed no deterioration of left or right ventricular function. In one patient with pre-existing mitral valve insufficiency (I°) an aggravation of the insufficiency (III°) was observed. No other valve dysfunctions were observed. The steep Trendelenburg position may improve haemodynamic function and does not deteriorate left or right ventricular function during RALP. However, mitral valve insufficiency may be aggravated by positioning and capnoperitoneum. Copyright © 2011 John Wiley & Sons, Ltd.

    Neuroblastoma (NB) is the most common extra-cranial solid tumor in children and the most common malignancy in infants, with complete resection being curative in low-stage disease. The previous standard of treatment for many abdominal NBs involving the adrenal gland had been open surgery; however, there have been numerous descriptions of the safety and feasibility of a laparoscopic approach to resect adrenal masses in the pediatric population in benign and malignant disease, including improved cosmetic results, decreased length of stay, decreased surgical morbidity, and comparable oncological outcomes to open surgery. Despite these reported advantages over open surgery, the newer robot-assisted laparoscopy (RAL) offers benefits over the conventional laparoscopic approach that could further improve outcomes and expand the use of minimally invasive surgical approaches for pediatric adrenal masses. RAL offers many additional advantages over conventional laparoscopy, such as 3D visualization, increased range of motion of surgical instruments, tremor control, and a shorter learning curve compared with traditional laparoscopic surgery, while still maintaining the advantages of minimally invasive surgery. The body of literature concerning robot-assisted oncological surgery involving the adrenal gland in children is quite small, and to our knowledge no case reports have been published describing robot-assisted removal of an adrenal NB in a pediatric patient. We present our experience and technique of an RAL approach for lymph-node dissection and radical resection of a low-stage NB involving the adrenal gland with no image-defined risk factors in a 15-month-old infant.

    Epiphrenic esophageal diverticulum is a rare condition that is often associated with a concomitant esophageal motor disorder. Some patients have the chief complaints of swallowing difficulty and gastroesophageal reflux; traditionally, such diverticula have been resected via right thoracotomy. Here, we describe a case with huge multiple epiphrenic diverticula with motility disorder, which were successfully resected using a video-assisted thoracic and laparoscopic procedure. A 63-year-old man was admitted due to dysphagia, heartburn, and vomiting. An esophagogram demonstrated an S-shaped lower esophagus with multiple epiphrenic diverticula (75 × 55 mm and 30 × 30 mm) and obstruction by the lower esophageal sphincter (LES). Esophageal manometry showed normal peristaltic contractions in the esophageal body, whereas the LES pressure was high (98.6 mmHg). The pressure vector volume of LES was 23,972 mmHg(2) cm. Based on these findings, we diagnosed huge multiple epiphrenic diverticula with a hypertensive lower esophageal sphincter and judged that resection might be required. We performed lower esophagectomy with gastric conduit reconstruction using a video-assisted thoracic and hand-assisted laparoscopic procedure. The postoperative course was uneventful, and the esophagogram demonstrated good passage, with no leakage, stenosis, or diverticula. The most common causes of mid-esophageal and epiphrenic diverticula are motility disorders of the esophageal body; appropriate treatment should be considered based on the morphological and motility findings.

    Traditional methods of nailing distal tibial fractures have an unacceptable risk of mal-alignment due to difficulty in obtaining and maintaining reduction intra-operatively. Methods to obtain and maintain reduction when nailing these fractures, and therefore reducing the risk of Mal-alignment include modified external fixators, distractors and commercial reduction tools. Semi-extended intramedullary nailing of distal tibial fractures via a supra-patellar approach is now being used more commonly. The aim of this study was to assess whether a commercial reduction device (Staffordshire Orthopaedic Reduction Machine - STORM, Intelligent Orthopaedics, Stafffordshire, UK) is necessary to reduce the risk of mal-alignment in patients undergoing semi-extended nailing for distal tibial fractures. A case-control study was conducted in 20 patients who had STORM-assisted reduction of distal tibial fractures prior to intramedullary nailing and 20 controls without STORM. The control group was matched for age, sex, fracture type (AO/OTA), ASA and gender. All patients had an intramedullary nail (IMN) using the semi-extended system. Primary outcome measures were coronal and sagittal mal-alignment. Secondary outcome measure was unplanned return to theatre for complications and problems with fracture healing. There was no difference in post-operative mal-alignment in both groups. There was no significant difference in time to union in both groups Both groups had equal number of patients requiring unplanned return to theatre. The STORM group was associated with a significantly increased operative time [p=0.007, 130.3min (SD 49.4) STORM vs 95.6 mins (SD 22.9) Control]. Intraoperative use of STORM significantly increases operative time with no difference in outcome. The superior orthogonal views and manual control obtained during semi-extended nailing via a supra-patellar approach obviate the need for additional methods: of intraoperative reduction for this fracture group.

    The article presents the results of laparoscopic choledoch-duodenostomy (CDS) applied to 23 patients with benign strictures of distal part of common bile duct (CBD). 21 patients had cholelithiasis in combination with the CBD stricture. The rest 2 patients had acalculous postcholecystectomy stricture. The laparoscopic CDS was executed by 5 trocars: 4 were placed in standard cholecystectomy positions and the 5th was placed by the right pararectal line at the umbilicus level and was used for traction of duodenum and continuous aspiration. 2 sm long side-to-side CDS was performed with interrupted sutures. The mean operative time was 128±36 (90-205) min. There was no conversion. The mean hospital stay was 4.5 (3-9) days. There was no mortality. 2 patients developed an anastomosis bile leakage: one received the relaparoscopy and T-draining of the CDS, in another patient the leakage seased spontaneously. 82.7% of patients showed excellent and good long term results. 3 patients reported bad outcome and very bad result was registered in 1 patient. In conclusion, the laparoscopic CDS gives good outcomes in experienced hands and could be considered as an alternative to endoscopic sphincterotomy in patients with distal CBD stenosis.

    There are multiple minimal invasive approaches to remove the adrenal gland. The purpose of this review is to summarize the most up-to-date findings about laparoscopic, retroperitoneoscopic, robot-assisted, and single-site adrenalectomy, and to define the most common approaches to the adrenal gland. Laparoscopic adrenalectomy is the gold standard to remove adrenal tumors. New approaches are being explored to outperform the advantages of laparoscopic adrenalectomy. Retroperitoneoscopic adrenalectomy, when performed by skilled surgeons, offers an alternative to the conventional laparoscopic approach, with better outcome. The robot-assisted and single-site approaches still need further studies to fully identify their roles in adrenalectomy.

    Full Text Available Introduction: We hypothesized that there is a reverse stage migration, or a shift toward operating on higher-risk prostate cancer, in patients undergoing robot-assisted laparoscopic prostatectomy (RALP. We therefore evaluated the stage of disease at the time of surgery for patients with prostate cancer at a large tertiary academic medical center. Materials and Methods: After institutional review board approval, we reviewed all patients that had undergone robotic prostatectomy. These patients were separated into three categories: An early era of 2005-2008, intermediate era of 2009-2010, and a current era of 2011-2012. Results: A total of 3451 patients underwent robotic prostatectomy from 2005 to 2012. The proportion men with clinical T1 tumors declined from 88.3% in the early era to 72.2% in the current era (P < 0.0001. Men with preoperative biopsy Gleason 6 disease decreased from the early to the current era (P < 0.0001, while men with preoperative biopsy Gleason ≥ 8 showed the opposite trend, increasing from the early to the current era (P = 0.0002. From the early to the current era, the proportion of patients with National Comprehensive Cancer Network (NCCN low risk prostate cancer decreased, while those with NCCN intermediate and high-risk disease increased. The proportion of pathologic T3 disease increased from 15.5% in the early to 30.6% in the current era (P < 0.0001. On the other hand, the proportion of pathologic T2/+ SMS (surgical margin status decreased from 6.6% in the early era to 3.1% in the current era (P = 0.0002. Conclusions: We have demonstrated a reverse stage migration in men undergoing robotic prostatectomy. Despite the increasing proportion of men with extra-capsular disease undergoing RALP, the surgical margin status has remained similar. This could reflect both the changing dynamics of the population opting for surgery as well as the learning curve of the surgeons.

    Full Text Available PURPOSE: V-LocTM180 (Covidien Healthcare, Mansfield, MA is a new unidirectional barbed suture that may reduce loss of tension during a running closure. We evaluated the use of the barbed suture for urethrovesical anastomosis (UVA during robotic assisted laparoscopic prostatectomy (RALP. Time to completion of UVA, post-operative anastomotic leak rate, and urinary incontinence were compared in patients undergoing UVA with 3-0 unidirectional-barbed suture vs. 3-0 MonocrylTM (Ethicon, Somerville, NJ. MATERIALS AND METHODS: Data were prospectively collected for 70 consecutive patients undergoing RALP for prostate cancer between November 2009 and October 2010. In the first 35 patients, the UVA was performed using a modified running van Velthoven anastomosis technique using two separate 3-0 monofilament sutures. In the subsequent 35 patients, the UVA was performed using two running novel unidirectional barbed sutures. At 7-12 days postoperatively, all patients were evaluated with a cystogram to determine anastomotic integrity. Urinary incontinence was assessed at two months and five months by total daily pad usage. Clinical symptoms suggestive of bladder neck contracture were elicited. RESULTS: Age, PSA, Gleason score, prostate size, estimated blood loss, body mass index, and clinical and pathologic stage between the 2 groups were similar. Comparing the monofilament group and V-LocTM180 cohorts, average time to complete the anastomosis was similar (27.4 vs. 26.4 minutes, p = 0.73 as was the rate of urinary extravasation on cystogram (5.7 % vs. 8.6%, p = 0.65. There were no symptomatic bladder neck contractures noted at 5 months of follow-up. At 2 months, the percentage of patients using 2 or more pads per day was lower in the V-LocTM180 cohort (24% vs. 44%, p < 0.02. At 5 months, this difference was no longer evident. CONCLUSIONS: Time to complete the UVA was similar in the intervention and control groups. Rates of urine leak were also comparable

    Acquisition of the da Vinci surgical system (Intuitive Surgical, Mountain View, USA) has enabled robot-assisted surgery to become an acceptable alternative to open radical prostatectomy (ORP). Implementation of robotics at a single institution in Korea induced a gradual increase in the number of performances of robot-assisted laparoscopic radical prostatectomy (RALP) to surgically treat localized prostate cancer. We analyzed the impact of robotic instrumentation on practice patterns among urologists and explain the change in value in ORP and RALP-the standard treatment and the new approach or innovation of robotic technology. The overall number of prostatectomies has increased over time because the number of RALPs has grown drastically whereas the number of OPRs did not decrease during the period of evaluation. Our experience emphasizes the potential of RALP to become the gold standard in the treatment of localized prostate cancer in various parts of the world.

    Minimally invasive surgery has revolutionized the treatment of gastrointestinal tumors. Submucosal tumors of the stomach can be resected using laparoscopic techniques. We report here a case of ectopic pancreas tissue in the gastric wall that was removed using robotic-assisted laparoscopic resection. The patient was a 15-year-old female who presented with abdominal discomfort and tarry stools. Laboratory analysis showed iron deficiency anemia. Preoperative endoscopy revealed a submucosal lesion in the posterior wall of the gastric high body. Intraoperative upper endoscopy clearly located the lesion. A robotic-assisted laparoscopic wedge resection of the putative gastric submucosal tumor was performed. The pathology results showed an ectopic pancreas. The patient had an uneventful recovery and we believe that this is a valid treatment option for this benign condition.

    Increasingly, robotic surgery is being used for total hysterectomy, bilateral salpingo-oophorectomy, and lymph node dissection for uterine cancer. The purpose of this study was to compare the costs and complications among women undergoing robotic and laparoscopic hysterectomy for uterine cancer. We carried out a cohort study using the Nationwide Inpatient Sample (NIS) database between 2008 and 2012 on all women diagnosed with uterine cancer, classifying women as either laparoscopically or robotically treated, excluding laparotomies or vaginal approaches. Logistic regression analyses were used to evaluate the adjusted effect of surgical approach on complication rates. There were 10,347 women who underwent hysterectomies for uterine cancer either laparoscopically (39%) or robotically (61%). The rate of robotic surgery consistently increased over the 5 year period. Women undergoing robotic surgery had more comorbid conditions (diabetes, hypertension, cardiovascular disease, renal disease, obesity or morbid obesity, and pulmonary disease). In adjusted analyses, women undergoing robotic surgery were more likely to have a lymph node dissection (73.01% vs 66.04%; P laparoscopic surgery. The composite endpoint of any complication was similar between both cohorts (20.56% robotic vs 21.00% laparoscopy). In overall and subset analyses, robotic surgery was more costly, with median charges of $38,161.00 compared with $31,476.00 in those undergoing laparoscopic surgery (P < .0001). Despite the considerably greater burden of comorbidities in those undergoing robotic surgery compared with laparoscopy, the former have shorter hospital admissions, a greater rate of lymph node dissection, and similar postoperative morbidity and mortality, albeit at greater total cost.

    Laparoscopic gastrointestinal surgery with lymphadenectomy is rarely performed for multiple gastrointestinal cancers. We report four patients undergoing laparoscopic surgery for synchronous cancer of the stomach and colon. Resection of each organ with lymphadenectomy was performed by each specialist and the region of the lymphadenectomy was determined according to the lesion of cancer and its depth. The selection of gastric anastomosis, whether intracorporeal or extracorporeal, depended on the resecting areas of the large bowel to allow a small incision. All four cases were male with the median age of 69 (range 59-77) years. The median number of trocars used were 6 (range 5-8) and median length of incision was 4.5 cm (range 4-4.5 cm). The median operative time and blood loss were 495.5 minutes (range 390-605) and 88 g (range 36-245), respectively. In all four cases, laparoscopic surgery with a lymphadenectomy on each region was successfully accomplished according to the respective progression stage. Anastomosis was completed with a small incision by using techniques and devices to provide a variation of anastomosis methods and incision positions. Laparoscopic surgery with lymphadenectomy was also undertaken for a patient with gastric remnant cancer and colorectal cancer. The median length of the postoperative hospital stay was 14.5 days (range 12-29). No complications were observed after the surgery. There was no case of recurrence during a median follow-up of 84.3 months (range 54.9-111.5). Laparoscopic surgery was feasible for patients with double cancer of the stomach and colon.

    To evaluate, in a simulated suturing task, individual surgeons’ performance using three surgical approaches: open, laparoscopic and robot-assisted. subjects and methods: Six urological surgeons made an in vitro simulated vesico-urethral anastomosis. All surgeons performed the simulated suturing task using all three surgical approaches (open, laparoscopic and robot-assisted). The time taken to perform each task was recorded. Participants were evaluated for perceived discomfort using the self-reporting Borg scale. Errors made by surgeons were quantified by studying the video recording of the tasks. Anastomosis quality was quantified using scores for knot security, symmetry of suture, position of suture and apposition of anastomosis. The time taken to complete the task by the laparoscopic approach was on average 221 s, compared with 55 s for the open approach and 116 s for the robot-assisted approach (anova, P errors and the level of self-reported discomfort were highest for the laparoscopic approach (anova, P robot-assisted surgery combines the accuracy of open surgery while causing lesser surgeon discomfort than laparoscopy and maintaining minimal access.

    Intra-articular malunion after fractures of the distal humerus can cause pain, stiffness and, consequently, osteoarthritis in the long run. Although corrective osteotomy for intra-articular malunion has been reported, it is still technically challenging and needs careful preoperative evaluation and planning. Here, we present two cases of corrective osteotomy assisted by preoperative three-dimensional (3-D) computer simulation. We present two cases of malunited intra-articular fracture of the distal humerus, which was treated by corrective osteotomy with the aid of 3-D computer simulation. One case was initially treated with closed reduction and pinning, and the other was initially treated with open reduction and internal fixation. Both of them had pain and severely limited range of motion in the elbow due to intra-articular malunion. 3-D models of the bilateral humeri were created on a computer using computed tomography (CT) data. The deformity was analyzed by superimposing the model of the affected humerus on the mirrored model of the contralateral normal humerus. Osteotomy, reduction and fixation were simulated preoperatively on the computer. The actual surgery was performed exactly according to the preoperative 3-D computer simulation. The operative procedures were performed successfully according to the computer simulation. Range-of-motion exercises started 3 days and immediately after the surgery in cases 1 and 2, respectively. Two years after surgery, there were no complaints of pain or instability. The range of elbow motion was 5°-140° and 15°-125° in cases 1 and 2, respectively. Plain radiographs and CT scans showed good reconstruction of the articular surface. 3-D computer simulations can be useful in preoperative planning for intra-articular corrective osteotomy for complex malunion of the distal humerus.

    Various factors including severe obesity or increases in intra-abdominal pressure during laparoscopy can lead to inaccuracies in end-tidal carbon dioxide (PETCO2) monitoring. The current study prospectively compares ET and transcutaneous (TC) CO2 monitoring in severely obese adolescents and young adults during laparoscopic-assisted bariatric surgery. Carbon dioxide was measured with both ET and TC devices during insufflation and laparoscopic bariatric surgery. The differences between each measure (PETCO2 and TC-CO2) and the PaCO2 were compared using a non-paired t test, Fisher's exact test, and a Bland-Altman analysis. The study cohort included 25 adolescents with a mean body mass index of 50.2 kg/m2 undergoing laparoscopic bariatric surgery. There was no difference in the absolute difference between the TC-CO2 and PaCO2 (3.2±3.0 mmHg) and the absolute difference between the PETCO2 and PaCO2 (3.7±2.5 mmHg). The bias and precision were 0.3 and 4.3 mmHg for TC monitoring versus PaCO2 and 3.2 and 3.2 mmHg for ET monitoring versus PaCO2. In the young severely obese population both TC and PETCO2 monitoring can be used to effectively estimate PaCO2. The correlation of PaCO2 to TC-CO2 is good, and similar to the correlation of PaCO2 to PETCO2. In this population, both of these non-invasive measures of PaCO2 can be used to monitor ventilation and minimize arterial blood gas sampling.

    Full Text Available Objective: To analyze the perioperative outcome of the first 190 cases of robot-assisted laparoscopic radical prostatectomy performed at our center from July 2006 to December 2010. Materials and Methods: Operative and recovery data for men with localized prostate cancer undergoing robot-assisted radical prostatectomy at our center were reviewed. All surgeries were performed using the 4-arm da Vinci-S surgical robot. Preoperative data included age, body mass index (BMI, prostate specific antigen (PSA level, prostate weight, biopsy Gleason score and TNM staging, while operative and recovery data included total operative time, estimated blood loss, complications, hospital stay and catheter time. These parameters were evaluated for the safety and efficacy of this procedure in our center. Results: The mean age of our patients was 65 ± 1.2 years. The mean BMI was 25.20 ± 2.88 and the median PSA was 14.8 ng/ml. Majority of our patients belonged to clinical stage T2 (51.58%. The mean total operative time was 166.44 ± 11.5 min. Six patients required conversion to open procedure and there was one rectal injury. The median estimated blood loss was 302 ± 14.45 ml and the median duration of hospital stay was 4 days. The overall margin positivity rate was 12.63%. Conclusion: Despite our limited robotic surgery experience, our perioperative outcome and complication rate is comparable to most contemporary series. Robot-assisted laparoscopic prostatectomy (RALP is easy to learn and provides the patient with the benefits of minimally invasive surgery with minimal perioperative morbidity.

    The aim of this study was to describe the technical aspects of a robotic pyeloplasty in pediatric patients with uretero-pelvic junction obstruction (UPJO) in horseshoe kidney (HSK) through the report of our recent case, and to outline the state of the art of minimally invasive pyeloplasty (MIP) with a systematic review of the literature. We describe all the steps of our surgery performed on an 11-year-old patient with left UPJO in HSK in detail. All the anatomic landmarks are clearly showed, with particular attention to trocar placement in a pediatric patient. A systematic review of the literature on the outcomes of MIP in HSK patients has been performed, including 16 articles. Our surgery was successful following a standardized approach. However, we recorded a rare complication, the herniation of a small portion of omentum through the 8 - mm defect used for the caudal robotic port. The evidence synthesis shows excellent postoperative outcomes for both laparoscopic and robot-assisted laparoscopic pyeloplasties in HSK patients. Probably, MIP should be preferred to the traditional open approach in these patients, when feasible. Transperitoneal robotic pyeloplasty is an excellent minimally invasive choice for the treatment of UPJO in HSK pediatric patients. The pediatric setting should prompt attention to every detail to avoid unfortunate complications.

    This study is aimed at verifying if the surgeon's experience has an impact on the risk of conversion to open surgery of laparoscopic left colectomy performed in obese patients. A multiple logistic regression analysis was performed of 181 laparoscopic left hemicolectomies completed between April 2001 and June 2006. The results were analysed statistically in relation to the learning curve, by comparing factors that could have had an impact on the risk of conversion in the first 91 cases and in the last 90 cases. The overall conversion rate was 11%. Only weight level was found to be predictive of conversion to open surgery. No death was observed. Sixteen patients presented postoperative complications (8.8%), with no significant differences between obese and nonobese patients (P=0.95). The conversion rate was higher in the group of the first 91 cases: 15.6% versus 6.6% (P=0.05). Average body mass index of converted patients resulted as being higher than that of nonconverted ones (29.97+/-3.76 vs. 25.48+/-3.72; Plearning curve, but the difference was not observed during the second period (P=0.87). On multiple logistic regression analysis, obesity was found to be predictive of conversion only during the first period. The data indicate that the laparoscopic colorectal surgery is feasible and effective in obese patients both when the surgeon is expert in laparoscopic colorectal resection and at the initial phase of the experience. At the initial phase of the experience obesity constitutes a higher risk of conversion to open surgery.

    2008-01-01

    The LAPMAN (Medsys, Gembloux, BELGIUM) is a dynamic laparoscope holder guided by a joystick clipped onto the laparoscopic instruments under the index finger of the operator. It confers optimal control of the visual field while operating, ensures stable and smooth displacement of the laparoscope, and allows the operator to work in conditions of restricted surgical assistance, due to either unavailability of staff or economic constraints. It has been tested successfully in pilot studies in laparoscopic gynecologic surgery.

  20. Pancreatic Surgery in the Laparoscopic Era

    2003-11-01

    subtotal pancreatectomy with or without preservation of the splenic vessels and spleen for neuroendocrine and cystic tumours, and in some patients with chronic pancreatitis is feasible and safe. In experienced hands, this minimally invasive approach reduces postoperative hospital stay and expedites recovery. However, the incidence of pancreatic fistula following distal resection is not any less than that of open surgery. Although the previous limited experience with laparoscopic pancreaticoduodenectomy was discouraging, the recent experience with the hand-assisted approach is quite favourable and is likely to expand.

    Objective. We sought to compare positive surgical margin rates (PSM), estimated blood loss (EBL), and quality of life outcomes (QOL) among perineal (RPP), retropubic (RRP), and robot-assisted laparoscopic (RALP) prostatectomies. Methods. Records from 463 consecutive men undergoing RPP (92), RRP (180), or RALP (191) for clinically localized prostate cancer were retrospectively reviewed. Age, percent tumor volume, Gleason score, stage, EBL, PSM, and QOL using the expanded prostate cancer index composite (EPIC) were compared. Results. PSM were similar when adjusted for stage, grade, and volume. EBL was significantly less in the RALP (189 ml) group compared to both RPP (475 ml) and RRP (999 ml) groups. When corrected for nerve sparing, there were no differences in erectile function and sexual function amongst the three groups. Urinary summary and pad usage scores showed no significant differences. Conclusion. RPP, RRP, and RALP offer similar surgical and QOL outcomes. RALP and RPP demonstrate less EBL compared to RRP.

    Abdominoperineal resection (APR) of anorectal cancers after neoadjuvant chemoradiotherapy may incur significant perineal morbidity. While vertical rectus abdominis muscle (V-RAM) flaps can fill the pelvic resection space with health tissue, their use has previously been described predominantly in association with laparotomy. Here, we describe a means of combination laparoscopic APR with V-RAM flap reconstruction that allows structural preservation of the entire abdominal wall throughout the oncological resection and of the deep parietal layers after V-RAM donation. Furthermore, a single port access device used at the end colostomy site allows a second senior surgeon assist with an additional two working instruments for the purpose of improved pelvic tissue retraction, especially useful in obese patients.

    Full Text Available We describe a simple and feasible procedure for single-incision laparoscopic repair of a pediatric epigastric hernia using a novel suture-assisting needle. A multichannel port was inserted through the umbilical vertical incision. After the orifice of the hernia was identified, a suture-assisting needle, which can hold a suture at its tip, with a 2-0 thread was pierced through the skin into one side of the rectus muscle sheath into the abdominal cavity. Next, after releasing the thread, the needle was pulled out to the subcutis and pierced through another side of the rectus muscle sheath. The needle, grasping the thread again, was subsequently pulled out through the abdominal wall outside, and the thread was tied extracorporeally. This knot was buried subcutaneously. Operative procedures of single-incision laparoscopic repair of an epigastric hernia have become simple and feasible with the use of a novel suture-assisting needle with an excellent cosmetic result.

    Full Text Available Partial laparoscopic splenectomy is performed commonly in hereditary spherocytosis. Vaccination against capsulatedbacteria is essential before undergoing splenectomy. Hand-assisted laparoscopic splenectomy is known to be effectiveand convenient in the removal of a spleen larger than 20 cm in size. Laparoscopic splenectomy provides less hemorrhage,reduced surgical trauma and pain, shorter duration of hospital stay, and early recovery. Laparoscopic approachwas particularly effective in reducing the infectious complication rate compared with the open surgery. Infectious complicationsof splenectomy were observed to be wound infection, subphrenic abscess, and sometimes pulmonary infection.J Microbiol Infect Dis 2013; 3(1: 1-2Key words: Laparoscopy, splenectomy, infection

    Full Text Available We report a case of xanthogranulomatous pyelonephritis (XGP complicated by shaped urolithiasis, severe hydroureteronephrosis and kidney exclusion treated by laparoscopic-assisted nephroureterectomy. A 9 year-old boy was referred to us for recurrent episodes of urinary tract infection, abdominal pain and severe hydronephrosis. Abdominal CT and a Tc-99m MAG3 scan showed a non-functioning obstructed kidney with shaped urolithiasis of the distal ureter. XGP was suspected, and nephroureterectomy was performed by laparoscopic distal ureterectomy and open extraperitoneal nephrectomy. This technique avoided the need for a more extended nephrectomy incision or even a second iliac incision. It also ensured complete excision of the distal ureter with minimal risk of developing the ureteral stump syndrome, which sometimes follows nephroureterectomy. We believe that laparoscopic-assisted nephroureterectomy may be a suitable technique in those cases of difficult nephrectomy where a ureteral stump syndrome is likely to develop.

    Robotic-assisted laparoscopic surgery is an emerging modality in the field of minimally invasive colorectal surgery. However, there is a dearth of data comparing outcomes with other minimally invasive techniques. We present a 3-arm (conventional, hand-assisted, and robotic) matched-case analysis of intraoperative and short-term outcomes in patients undergoing minimally invasive colorectal procedures. Between August 2008 and October 2009, 70 robotic cases of the rectum and rectosigmoid were performed. Thirty of these were organized into triplets with conventional and hand-assisted cases based on the following 6 matching criteria: 1) surgeon; 2) sex; 3) body mass index; 4) operative procedure; 5) pathology; and 6) history of neoadjuvant therapy in malignant cases. Demographics, intraoperative parameters, and postoperative outcomes were assessed. Pathological outcomes were analyzed in malignant cases. Data were stratified by postoperative diagnosis and operative procedure. There was no significant difference in intraoperative complications, estimated blood loss (126.1 ± 98.5 mL overall), or postoperative morbidity and mortality among the groups. Robotic technique required longer operative time compared with conventional laparoscopic (P arm case-matched series, the robotic approach results in short-term outcomes comparable to conventional and hand-assisted laparoscopic approaches for benign and malignant diseases of the rectum and rectosigmoid. With 3-dimensional visualization, additional freedom of motion, and improved ergonomics, this enabling technology may play an important role when performing colorectal procedures involving the pelvic anatomy.

    Full Text Available Background: Hysterectomy is the most frequently surgery done with robotic assistance in the world and has been widely studied since its emergence. The surgical outcomes of the robotic hysterectomy are similar to those obtained with other minimally invasive hysterectomy techniques (laparoscopic and vaginal and appear as a promising surgical technique in gynaecology surgery. The aim of this study was to observe the learning curve of robot-assisted hysterectomy in a French surgical center, and was to evaluate the impact of the surgical mentoring.Methods: We retrospectively collected the data from the files of the robot-assisted hysterectomies with the Da Vinci® Surgical System performed between March 2010 and June 2014 at the Foch hospital in Suresnes (France. We first studied the operative time according to the number of cases, independently of the surgeon to determine two periods: the initial learning phase (Phase 1 and the control of surgical skills phase (Phase 2. The phase was defined by mastering the basic surgical tasks. Secondarily we compared these two periods for operative time, blood losses, Body Mass Index (BMI, days of hospitalisations and uterine weight. We finally studied the difference of the learning curve between an experimented surgeon (S1 who practised the first the robot-assisted hysterectomies and a less experimented surgeon (S2 who first assisted S1 and then operated on his own patients.Results: 154 robot-assisted hysterectomies were analysed. 20 procedures were necessary to access to the control of surgical skills phase. There was a significant decrease of the operative time between the learning phase (156.8 minutes compared to the control of surgical skills phase (125.8 minutes, p=0.003. No difference between these two periods for blood losses, BMI, days of hospitalisations and uterine weight were demonstrated. The learning curve of S1 showed 20 procedures to master the robot-assisted hysterectomies with a significant

This study aimed to investigate the influence of obesity on the surgical outcomes of laparoscopy-assisted distal gastrectomy (LADG) for gastric cancer. The clinical data of 131 patients with gastric cancer from January 2010-December 2013 were analyzed retrospectively. Perioperative outcomes were compared between 43 patients with a body mass index (BMI) ≥30 kg/m(2) (obese group) and 88 patients with a BMI obese group than for the nonobese group (234.1 ± 57.2 min versus 212.2 ± 43.5 min, P = 0.026). There were no statistically significant differences between two groups in terms of intraoperative blood loss, the number of retrieved lymph nodes, postoperative recovery, and postoperative complications (P > 0.05). During the follow-up period of 5 mo-49 mo (average, 36 mo), the overall survival rates were not significantly different between the two groups (80.0% [32/40] versus 81.9% [68/83], P > 0.05). The differences in recurrence and metastasis between the two groups were not statistically significant. Our analysis revealed that LADG can be safely performed in patients with BMI ≥30. The procedure was considered to be difficult but sufficiently feasible. Copyright © 2015 Elsevier Inc. All rights reserved.

    A case of moving ileal Taenia saginata parasites is presented with demonstrative images. We came across the parasites surprisingly while performing robot-assisted laparoscopic radical cystoprostatectomy with intracorporeal Studer pouch urinary diversion. We recommend stool sample evaluation in the preoperative period for possible presence of intestinal parasitic diseases, particularly in patients with bladder cancer who are admitted from areas with an increased incidence of intestinal parasitic diseases, before opening the bowel segments during surgery to perform radical cystectomy and urinary diversion.

    Full Text Available INTRODUCTION: We performed a laparoscopic radical cystoprostatectomy followed by constructing a Y-shaped reservoir extra-corporeally with titanium staples through a 5-cm muscle-splitting Pfannenstiel incision. SURGICAL TECHNIQUE: Upon completion of the extirpative part of the operation, the surgical specimen was entrapped and removed intact through a 5-cm Pfannenstiel incision. Through the extraction incision, the distal ileum was identified and a 40 cm segment isolated. With the aid of the laparoscope, the ureters were brought outside the abdominal cavity and freshened and spatulated for approximately 1.5-cm. Bilateral double J ureteral stents were then inserted up to the renal pelvis and the ureters were directly anastomosed to the open ends of the limbs of the neobladder. Following this, the isolated intestinal segment was arranged in a Y shape with two central segments of 14 cm and two limbs of 6 cm. The two central segments were brought together and detubularized, with two sequential firings of 80 x 3.5 mm and 60 x 3.5 mm non-absorbable mechanical stapler (Multifire GIA - US Surgical inserted through an opening made at the lowest point of the neobladder on its anti-mesenteric border. The neobladder was reinserted inside the abdominal cavity and anastomosed to the urethra with intracorporeal laparoscopic free-hand suturing. CONCLUSION: Although this procedure is feasible and the preliminary results encouraging, continued surveillance is necessary to determine the lithiasis-inducing potential of these titanium staples within the urinary tract.

    To assess the safety and feasibility of total laparoscopy distal gastrectomy (TLDG). This meta-analysis was conducted between April and July 2013 in Sichuan Cancer Hospital, Chengdu, China. We searched PubMed, EMBASE and China Knowledge Resource Integrated Database updated until May 2013. Eight retrospective studies and one prospective study involving 2,046 total patients were included. The results showed that TLDG was associated with lower blood loss (mean difference=-22.39, p=0.04). and a greater number of harvested lymph nodes (mean difference=2.74, p=0.02). There was no significant difference between the 2 groups in operation time, time to first flatus, length of postoperative hospital stay, and postoperative complications. Compared with laparoscopy-assisted distal gastrectomy, TLDG resulted in reduced blood loss, and a greater number of harvested lymph nodes. Total laparoscopy distal gastrectomy is safe and feasible for gastric cancer.

    ABSTRACT Introduction Robotic-assisted radical prostatectomy (RAP) is the dominant minimally invasive surgical treatment for patients with localized prostate cancer. The introduction of robotic assistance has the potential to improve surgical outcomes and reduce the steep learning curve associated with conventional laparoscopic radical prostatectomy. The purpose of this video is to demonstrate the early retrograde release of the neurovascular bundle without open the endopelvic fascia during RAP. Materials and Methods A 51-year old male, presenting histological diagnosis of prostate adenocarcinoma, Gleason 6 (3+3), in 4 cores of 12, with an initial PSA=3.41ng/dl and the digital rectal examination demonstrating a prostate with hardened nodule in the right lobe of the prostate base (clinical stage T2a). Surgical treatment with the robot-assisted technique was offered as initial therapeutic option and the critical technical point was the early retrograde release of the neurovascular bundle with endopelvic fascia preservation, during radical prostatectomy. Results The operative time was of 89 minutes, blood loss was 100ml. No drain was left in the peritoneal cavity. The patient was discharged within 24 hours. There were no intraoperative or immediate postoperative complications. The pathological evaluation revealed prostate adenocarcinoma, Gleason 6, with free surgical margins and seminal vesicles free of neoplastic involvement (pathologic stage T2a). At 3-month-follow-up, the patient lies with undetectable PSA, continent and potent. Conclusion This is a feasible technique combining the benefits of retrograde release of the neurovascular bundle, the preservation of the pubo-prostatic collar and the preservation of the antero-lateral cavernous nerves.

    Distal locking of intramedullary nails (IMNs) is a difficult part of intramedullary nailing (IMN) that could be time-consuming and expose the surgeon, the surgery personnel and the patient to a considerable amount of radiation as fluoroscopy is usually guiding the procedure. Utilization of electromagnetic fields for that purpose offers an attractive alternative. The SURESHOT™ Distal Targeting System (Smith & Nephew, Inc., Memphis, TN, USA) is a novel commercially available radiation-free aiming system that utilizes computerized electromagnetic field tracking technology for the distal locking of IMNs. In order to evaluate the efficacy of the system we conducted the present study. Nineteen patients (six females-thirteen males, mean age 39.5 years, range 17-85 years) with closed diaphyseal fracture of the femur (eight patients) or the tibia (eleven patients) were treated with IMN using the SURESHOT™ Distal Targeting System for the distal interlocking. All targeting attempts were successful at first try and followed by correct positioning of the screws. Mean time for distal locking of tibial IMNs (two screws) was 219sec (range 200-250sec). Mean time for distal locking of femoral IMNs (two screws) was 249 (range 220-330sec). In the current study the SURESHOT™ Distal Targeting System proved to be accurate, fast and easy to learn.

    Full Text Available Modern laparoscopic surgery is widely used throughout the world as it offers greater advantages than open procedures. The laparoscopic approach to hysterectomy has evolved over the last 20 years. Hysterectomies are performed abdominally, vaginally, laparoscopically or, more recently, with robotic assistance. Indications for a total laparoscopic hysterectomy are similar to those for total abdominal hysterectomy, and most commonly include uterine leiomyomata, pelvic organ prolapse, and abnormal uterine bleeding. When hysterectomy is going to be performed, the surgeon should decide which method is safer and more cost-effective. This paper aims to make a review of the indications, techniques and advantages of laparoscopic hysterectomy as well as the criteria to be used for appropriate patient selection.

    Full Text Available Radical prostatectomy (RP continues to be the «gold standard» in the treatment of localized prostate cancer (PC for patients with a life expectancy of 10 years.The purpose of this article is to review pertinent literature to the several surgical approaches for PC and compare both functional outcomes and oncological results of radical retropubic prostatectomy (RRP, laparoscopic radical prostatectomy (LRP and robot-assisted radical prostatectomy (RARP. We chose and systematically reviewed 44 articles published between 1999 and 2013. Comparison analysis showed that the mean blood loss during RRP, LRP and RARP was 935, 442 and 191 ml respectively. Intraoperative transfusion required 19,9; 6,3 and 4,6 % patients respectively. We’d like to outline in our functional outcomes that within the 6-months and 12-months period of follow-up acute urinary retention experienced 89,1 and 92,7 % patients undergoing RARP.However, lack of certain data and absence of standard assessment methods made objective evaluation of erectile function quite complex. Oncologic results revealed that positive surgical margin rates were higher for RARP in comparison to patients after RRP and LRP (the difference was statistically significant.Nevertheless, the absence of randomized approach in an overwhelming majority of cases, as well as the short follow-up period are serious deterrents limiting the number of such trials. Therefore it’s still impossible today to draw certain conclusions about the superiority of any surgical approach for RP

    Compared to laparotomic surgery, laparoscopically assisted radical vaginal hysterectomy (LARVH) offers decreased blood loss during surgery and faster convalescence of the patient postoperatively, while at the same time delivering similar oncologic results. However, there is no data on outcome and toxicity of LARVH followed by (chemo)radiation. A total of 55 patients (range 28-78 years) with cervical cancer on FIGO stages IB1-IIIA (Tables 1 and 2) with risk factors were submitted to either external beam radiotherapy alone [EBRT, n = 8 (14%), including paraaortic irradiation, n = 4 (2.2%); EBRT and brachytherapy (BT), n = 33 (60%); BT alone, n = 14 (25.5%)] or chemoradiation after LARVH. At a median follow-up of 4.4 years, the 5-year disease-free survival (DFS) was 81.8% with 84.5% overall survival (OS). Acute grade 3 side effects were seen in 4 patients. These were mainly gastrointestinal (GI) and genitourinary (GU) symptoms. Grade 4 side effects were not observed. With similar oncologic outcome data and mostly mild side effects, LARVH followed by (chemo)radiation is a valid alternative in the treatment of cervical cancer patients. (orig.)

    Surgeries, such as radical cystectomy (RC), induce a systemic inflammatory response (SIR). SIR plays an important role in controlling the human immune system. This study aims at comparing the SIR in robot-assisted laparoscopic cystectomy (RALC) to open mini-laparotomy cystectomy (OMC) with a urinary diversion (UD). Comparison was based on immunologic markers of SIR, thus quantifying the degree of tissue trauma. Forty-two male patients underwent RC with an ileal conduit. Either OMC RC (OMC; n = 20), RALC with extracorporeal UD (RALC-EUD; n = 13), or RALC with intracorporeal UD (RALC-IUD; n = 9) was performed. Blood samples were obtained preoperatively (PREOP), immediately after surgery (POD0), 24 (POD1) and 48 h (POD2) postoperatively. Clinical parameters were collected from medical records. Estimated blood loss and blood transfusion volume was higher in OMC (p's OMC (p = 0.016). IL-10 level was higher at POD0 (p = 0.029) and POD1 (p = 0.038) in OMC vs. RALC-EUD. MCP-1 levels for RALC-IUD were significantly lower compared to RALC-EUD (p = 0.027). This study found that postoperative SIR was overall less pronounced in RALC, thus depicting reduced tissue trauma. No major clinical differences between RALC-IUD and -EUD were found. © 2017 S. Karger AG, Basel.

    Full Text Available Objective. We sought to compare positive surgical margin rates (PSM, estimated blood loss (EBL, and quality of life outcomes (QOL among perineal (RPP, retropubic (RRP, and robot-assisted laparoscopic (RALP prostatectomies. Methods. Records from 463 consecutive men undergoing RPP (92, RRP (180, or RALP (191 for clinically localized prostate cancer were retrospectively reviewed. Age, percent tumor volume, Gleason score, stage, EBL, PSM, and QOL using the expanded prostate cancer index composite (EPIC were compared. Results. PSM were similar when adjusted for stage, grade, and volume. EBL was significantly less in the RALP (189 ml group compared to both RPP (475 ml and RRP (999 ml groups. When corrected for nerve sparing, there were no differences in erectile function and sexual function amongst the three groups. Urinary summary and pad usage scores showed no significant differences. Conclusion. RPP, RRP, and RALP offer similar surgical and QOL outcomes. RALP and RPP demonstrate less EBL compared to RRP.

    Laparoscopy assisted distal gastrectomy (LADG) for gastric cancer has been rapidly adopted for the treatment of both early and advanced gastric cancers which need lymph node dissection, but remains difficult procedure, especially in patients with obesity. We evaluated the impact of obesity on short- and long-term outcomes of LADG for gastric cancer. We retrospectively investigated 243 patients who underwent LADG for gastric cancer between January 2007 and December 2014. The patients were classified based on their body mass index (BMI) into the Obese (BMI ≥ 25) and Non-Obese (BMI Obese Group. Fewer lymph nodes were retrieved in the Obese Group (38 ± 23.7 vs. 47.5 ± 24.3; P = 0.004). No differences were evident in postoperative complication rate (20% vs. 17%; P = 0.688) or the duration of postoperative hospital stay (9 ± 8.5 vs. 9 ± 5.1 days; P = 0.283) between the two groups. In the Obese Group, the 5-year overall survival rate was significantly lower than in the Non-Obese Group (67.6% vs. 90.3%; P = 0.036). Furthermore, 5-year disease-specific survival was significantly lower in the Obese Group than in the Non-Obese Group (72.7% vs. 94.9%; P = 0.015). LADG in patients with obesity could be performed as safe as in patients without obesity, with comparable postoperative results. But obesity may be a poor prognostic factor in gastric cancer.

    2010-06-01

    Full Text Available Excision of renal cell carcinoma (RCC with corresponding vena cava thrombus is a technical challenge requiring open resection and vascular clamping. A 58 year old male with a right kidney tumor presented with a thrombus extending 1 cm into the vena cava. Using a hand-assisted transperitoneal approach through a 7 cm gel-port, the right kidney was dissected and the multiple vascular collaterals supplying the tumor were identified and isolated. The inferior vena cava was mobilized 4 cm cephalad and 4 cm caudal to the right renal vein. Lateral manual traction was applied to the right kidney allowing the tumor thrombus to be retracted into the renal vein, clear of the vena cava. After laparoscopic ultrasonographic confirmation of the location of the tip of the tumor thrombus, an articulating laparoscopic vascular stapler was used to staple the vena cava at the ostium of the right renal vein. This allowed removal of the tumor thrombus without the need for a Satinsky clamp. The surgery was completed in 243 minutes with no intra-operative complications. The entire kidney and tumor thrombus was removed with negative surgical margins. Estimated blood loss was 300 cc. We present a laparoscopic resection of a renal mass with associated level II thrombus using a hand-assisted approach. In patients with minimal caval involvement, our surgical approach presents an option to the traditional open resection of a renal mass.

    Total extraperitoneal preperitoneal (TEP) repair is widely used for inguinal, femoral, or obturator hernia treatment. However, mesh repair is not often used for strangulated hernia treatment if intestinal resection is required because of the risk of postoperative mesh infection. Complete mesh repair is required for hernia treatment to prevent postoperative recurrence, particularly in patients with femoral or obturator hernia. We treated four patients with inguinocrural and obturator hernias (a 72-year-old male with a right indirect inguinal hernia; an 83-year-old female with a right obturator hernia; and 86- and 82-year-old females with femoral hernias) via a two-stage laparoscopic surgery. All patients were diagnosed with intestinal obstruction due to strangulated hernia. First, the incarcerated small intestine was released and then laparoscopically resected. Further, 8-24 days after the first surgery, bilateral TEP repairs were performed in all patients; the postoperative course was uneventful in all patients, and they were discharged 5-10 days after TEP repair. At present, no hernia recurrence has been reported in any patient. The two-stage laparoscopic treatment is safe for treatment of strangulated inguinal, femoral, and obturator hernias, and complete mesh repair via the TEP method can be performed in elderly patients to minimize the occurrence of mesh infection.

Conclusion: Our results suggest that prior experience of LPN shortens the learning curve for RPN as seen by shorter warm ischemia time and operative time in our series. The nephrometry score in RPN were higher suggesting that complex tumour can be managed with robotic approach.

    Laparoendoscopic technology has revolutionized the practice of surgery; however, surgeons have not widely accepted laparoscopic techniques for pancreatic surgeries due to the complexity of the operation. Natural orifice transluminal endoscopic surgery (NOTES) offers a great new potential for pancreatic procedures, with early data showing benefits of reduced visible scarring and the potential for decreased wound infections, hernias, pain, and postoperative complications. However, there are significant limitations to the currently used flexible endoscopy tools, including a diminished visual field, spatial orientation and tissue manipulation issues, and 2-dimensional visual feedback. We have adopted a novel snake-like robot, the minimally invasive cardiac surgery (MICS) robot, which addresses these issues. In the current pilot study, the MICS robot was evaluated for transrectal distal pancreas exploration and resection in 2 nonsurvival porcine models. Abdominal navigation and accessing the pancreas was investigated in the first pig, and based on its success, pancreas resection was studied in pig 2. The MICS robot was successful in accessing and visualizing the right upper, left upper, and left lower quadrants of the abdomen in pig 1 and was able to perform a successful complex NOTES procedure with distal pancreas resection in pig 2, with only minimal laparoscopic retraction assistance. In conclusion, preliminary results showing the MICS robot in natural orifice distal pancreatectomy are positive. Enhancements to optics and instrumentation will help further increase the usability in pancreatic interventions. Future indications may include transgastric NOTES approaches, endoluminal procedures, and single-port applications.

  16. Miniscrew-assisted mandibular molar distalization in a patient with skeletal class-III malocclusion: A clinical case report

    Full Text Available In nongrowing patients with mild skeletal Class-III malocclusion, premolar extraction or molar distalization in the lower arch can be done as a part of camouflage treatment. Temporary anchorage devices are widely used for this purpose because they do not produce undesirable reciprocal effects and do not depend on the patient′s cooperation. However, most reported cases in this regard have used interradicular miniscrews in the mandibular arch and these have a risk of failure as they can loosen due to collision with adjacent roots. This article showcases mandibular molar distalization utilizing miniscrews, inserted at the retromolar area to correct a Class-III problem. A 24-year-old girl with a mild skeletal Class-III malocclusion and dental Class-III molar and canine relationship bilaterally was referred for orthodontic treatment. The treatment plan included distalization of the lower molars bilaterally followed by full fixed appliance therapy, after third molar extractions. For the lower molar distalization, the miniscrews were inserted at the retromolar pad. At the end of 21 months, a Class-I molar and canine relationship, normal overjet and overbite were obtained. The average amount of distalization of mandibular first molar was 3.2 mm at the crown level. In conclusion, placing miniscrews at the retromolar pad area for lower molar distalization was found to be a simple and effective method for correcting anterior cross bite and mandibular anterior crowding or protrusion, without the need for patient compliance.

    Full Text Available Distal extension removable partial denture is a prosthesis with lack of distal dental support with a 13-fold difference in resiliency between the mucosa and the periodontal ligament, resulting in leverage during compression forces. It may be potentially destructive to the abutments and the surrounding tissues. The aim of this study was to assess the effect of implant location on stress distribution, in distal extension implant assisted removable partial dentures.Three-dimensional models of a bilateral distal extension partially edentulous mandible containing anterior teeth and first premolar in both sides of the arch, a partial removable denture and an implant (4×10mm were designed. With the aid of the finite element program ANSYS 8.0, the models were meshed and strictly vertical forces of 10 N were applied to each cusp tip. Displacement and von Mises Maps were plotted for visualization of results.When an implant was placed in the second premolar region, the highest stress on implant, abutment tooth and cancellous bone was shown. The lowest stress was shown on implant and bone in the 1(st molar area.Implants located in the first molar area showed the least distribution of stresses in the analyzed models.

    The traditional open surgery, for the treatment of huge tumor in the narrow space of pelvic cavity and in close proximity to pelvic organs and neurovascular structures, is very difficult and challenging. We report a case of huge neurilemmoma operated using the robot-assisted laparoscopy. We used interventional pre-operation embolization to control blood supply of tumor because MRI showed the tumor had a sufficient blood supply.

    We describe our technique of achieving transient vascular occlusion utilizing Hem-o-Lok clips during robotassisted laparoscopic partial nephrectomy (RLPN) A once-folded vascular loop is threaded through a 2-cm feeding tube. After passing around the renal vessel, its tail goes through the U-loop, creating a tourniquet. Vascular occlusion begins when the tube slides towards the vessel and a Hem-o-Lok clip is applied on the vascular loop next to the exposed end of the tube. When no longer needed, it is released. Since July 2006, 25 patients underwent RLPN utilizing this technique, which required bulldog or Satinsky clamps.

    Full Text Available Laparoscopic approaches have been increasingly used in selected patients with either colorectal or liver cancer. However, simultaneous resection of colorectal carcinoma with synchronous liver metastases is still a subject of debate. The present case describes combined laparoscopic rectal and liver resections for a patient with primary rectal cancer and a synchronous liver metastasis utilizing a Pfannenstiel incision for specimen extraction. The operative time was 370 min and estimated blood loss was 400 mL. Postoperatively, the patient required parenteral analgesia for 48 h, resumed normal diet on day 3 and was discharged on day 7 after the operation. A laparoscopic approach utilizing a Pfannenstiel extraction incision may present an advantageous and attractive option for simultaneous laparoscopic rectal and liver resection in selected patients with the aim of improving short-term outcomes.

    The cumulative summation (CUSUM) method for learning curve analysis remains under-utilized in the surgical literature in general, and is described in only a small number of publications within the field of pediatric surgery. This study introduces the CUSUM analysis technique and applies it to evaluate the learning curve for pediatric robot-assisted laparoscopic pyeloplasty (RP). Clinical data were prospectively recorded for consecutive pediatric RP cases performed by a single-surgeon. CUSUM charts and tests were generated for set-up time, docking time, console time, operating time, total operating room time, and postoperative complications. Conversions and avoidable operating room delay were separately evaluated with respect to case experience. Comparisons between case experience and time-based outcomes were assessed using the Student's t-test and ANOVA for bi-phasic and multi-phasic learning curves respectively. Comparison between case experience and complication frequency was assessed using the Kruskal-Wallis test. A total of 90 RP cases were evaluated. The learning curve transitioned beyond the learning phase at cases 10, 15, 42, 57, and 58 for set-up time, docking time, console time, operating time, and total operating room time respectively. All comparisons of mean operating times between the learning phase and subsequent phases were statistically significant (P=learning curve evaluation and outcome quality monitoring. In applying this statistical technique to the largest reported single surgeon series of pediatric RP, we demonstrate numerous distinctly shaped learning curves and well-defined learning phase transition points.

    In Japan, as of September 2007, prostatectomy is conducted with open surgical procedures in more than 90% of the cases. Following the first reported robotic prostatectomy by Binder, et al. in 2000, a robotic-assisted laparoscopic radical prostatectomy (RALP) using the daVinci Surgical System (Intuitive Surgical, Inc., Sunnyvale, California, USA) has been extensively used as a standard procedure with gratifying results in the United States. In the Asian region, in contrast, RALP is still in an introductory phase. Recently, we introduced RALP in Japan. A total of 24 patients received robotic surgery within a year since August 2006. RALP was completed in all patients without conversion to open surgery, except for the first patient in whom a restriction to a 2-hour operation had been imposed by the Ethical Committee. The mean operative time using the daVinci device and the mean estimated blood loss were 232.0 (range; 136-405) minutes and 313.0 (range; 10-1,000) ml, respectively. The training program we recently developed proved remarkably effective in reducing the learning curve of robotic surgery in Japan, where there is no person with expertise in this operating procedure. In particular, the intraoperative guidance given by the expert was useful after relevant problematic points were delineated by operators who received comprehensive video-based image training and actually performed robot surgery in several cases. With direct intraoperative guidance by the mentor during cases 13 and 14, both the operation time and estimated blood loss was markedly reduced.

    Full Text Available ABSTRACT Purpose: To evaluate the influence of prior abdominal surgery on the outcomes after robotic-assisted laparoscopic radical prostatectomy (RALP. Materials and Methods: We retrospectively analyzed patients with prostate cancer who underwent RALP between June 2012 and February 2015 at our institution. Patients with prior abdominal surgery were compared with those without prior surgery while considering the mean total operating, console, and port-insertion times; mean estimated blood loss; positive surgical margin rate; mean duration of catheterization; and rate of complications. Results: A total of 203 patients who underwent RALP during the study period were included in this study. In all, 65 patients (32% had a prior history of abdominal surgery, whereas 138 patients (68% had no prior history. The total operating, console, and port-insertion times were 328 and 308 (P=0.06, 252 and 242 (P=0.28, and 22 and 17 minutes (P=0.01, respectively, for patients with prior and no prior surgery. The estimated blood losses, positive surgical margin rates, mean durations of catheterization, and complication rates were 197 and 170 mL (P=0.29, 26.2% and 20.2% (P=0.32, 7.1 and 6.8 days (P=0.74, and 12.3% and 8.7% (P=0.42, respectively. Furthermore, whether prior abdominal surgery was performed above or below the umbilicus or whether single or multiple surgeries were performed did not further affect the perioperative outcomes. Conclusions: Our results suggest that RALP can be performed safely in patients with prior abdominal surgery, without increasing the risk of complications.

    Full Text Available ABSTRACTPurpose:To assess whether retinal and central nervous system (CNS comorbidities are risk factors for complications following robotic assisted laparoscopic prostatectomy (RALP.Materials and Methods:A retrospective review of our RALP database identified 1868 patients who underwent RALP by a single surgeon between December 10, 2003-March 14, 2014. We hypothesized that patients with preexisting retinal or CNS comorbidities were at a greater risk of suffering retinal and CNS complications following RALP. Perioperative complications and risk of recurrence were graded using the Clavien and D'Amico systems, respectively.Results:40 (2.1% patients had retinal or CNS-related comorbidities, of which 15 had a history of retinal surgery and 24 had a history of cerebrovascular accident, aneurysm and/or neurosurgery. One additional patient had a history of both retinal and CNS events.Patients with retinal or CNS comorbidities were significantly older, had elevated PSA levels and CCI (Charlson Comorbidity Index scores than the control group. Blood loss, length of stay, surgical duration, BMI, diagnostic Gleason score and T-stage were not statistically different between groups.No retinal or CNS complications occurred in either group. The distribution of patients between D'Amico risk categories was not statistically different between the groups. There was also no difference in the incidence of total complications between the groups.Conclusions:RALP-associated retinal and CNS complications are rare. While our RALP database is large, the cohort of patients with retinal or CNS-related comorbidities was relatively small. Our dataset suggests retinal and CNS pathology presents no greater risk of suffering from perioperative complications following RALP.

    To determine the feasibility and long-term outcomes of hand-assisted laparoscopic nephroureterectomy (HALNU) compared with open nephroureterectomy (ONU) in the management of pT(3)N0 upper urinary tract urothelial carcinoma (UUT-UC). Between January 1994 and December 2005, 21 patients who underwent HALNU for stage pT(3)N0 UTT-UC were matched and compared with 31 patients who underwent ONU. The oncologic out-comes, including bladder recurrence, recurrence-free survival, cancer-specific survival, and overall survival, were statistically analyzed. The median follow-up period in the HALNU group was 72 months (range 33-111 months) and 115 months in the ONU group (range 24-161 months). Patient age, sex, body mass index, tumor size, specimen weight, and American Society of Anesthesiologists classification showed no significant difference between the two groups. The HALNU group had statistically less blood loss than the ONU group (113 mL versus 487 mL; P = 0.02). The average hospital stay and doses of narcotic analgesics were significantly less in the HALNU group than the ONU group. The complication and bladder recurrence rates were similar between the two groups. The 5-year recurrence-free survival, cancer-specific survival, and overall survival were also comparable in both groups. HALNU is a safe and efficacious procedure with comparable long-term oncologic outcomes in comparison with ONU in treating patients with locally advanced pT(3)N0UUT-UC.

    Full Text Available Several factors may highlight the relevance of prostate cancer to the pre-heart-transplant population. First, the expansion in candidate selection criteria led to increased number of men over the age of fifty to be considered for heart transplantation. With the introduction of left ventricular assist device (LVAD therapy, waiting-list mortality has dramatically declined over the past decade. Additionally, transplant candidates are diligently screened for preexisting neoplasm while on the waiting list. Taken together, screening-detected prostate cancer may increasingly be diagnosed in patients on the waiting list. If discovered, it will pose unique challenge to clinicians as to date there has been no universally accepted management guideline. We report a case of LVAD-treated heart transplant candidate diagnosed with prostate cancer while on the waiting list. Patient screening demonstrated PSA elevation which prompted prostate biopsy. Low-risk clinically localized prostate cancer was confirmed and led to removal of patient from transplant list. When counseled regarding management of his cancer, the patient elected to undergo radical prostatectomy in a hope to regain candidacy for heart transplantation. Despite being of high surgical risk, multidisciplinary team approach led to successful management of prostate cancer and the patient eventually received heart transplant one year following prostatectomy.

    Full Text Available Abstract Background Laparoscopically-assisted right hemicolectomy (LRH is an acceptable alternative to open surgery for right-sided colon cancer which offers patients less pain and faster recovery. However, special equipment and substantial surgical experience are required. The aim of the study is to compare the short-term surgical outcomes of LRH and open right hemicolectomy through right transverse skin crease incision (ORHT for right-sided colon cancer. Patients and methods This retrospective study included 33 patients with right-sided colon cancer who underwent elective right hemicolectomy by laparoscopic or open approaches through right transverse skin crease incision between March 2004 and September 2006 at the Department of Surgery, Faculty of Medicine Siriraj Hospital. Operative details, postoperative requirement of narcotics, recovery of bowel function, and oncological parameters were analyzed. Results Thirteen patients underwent LRH and 20 patients underwent ORHT. Both approaches achieved adequate oncological resection of the tumor. The laparoscopic group were characterized by shorter average incision lengths (7.7 vs 10.3 cm; p Conclusion LRH and ORHT for right-sided colon cancer resulted in the same short-term surgical outcomes including postoperative bowel function, narcotics consumption and length of hospital stay. However, LRH required a significantly longer operating time.

    Transversus abdominis plane (TAP) block has been used as a component of multimodal analgesia after abdominal operation. We introduced a new laparoscope-assisted TAP (LTAP) block technique using intraperitoneal injection and compared its analgesic effect with that of an ultrasound-guided TAP (UTAP) block in terms of postoperative pain control. A prospective, randomized, single-blinded non-inferiority clinical trial was conducted with patients undergoing elective laparoscopic colectomy for colon cancer. Eighty patients were randomly assigned (1:1 ratio) to the UTAP and LTAP groups. At the end of the operation, opioid consumption and numeric rating scores (NRS; 0 [no pain] to 10 [worst pain]) of pain were recorded at 2, 6, 24, and 48 hours postoperatively and were compared between the groups. The primary end point was pain NRS during rest at 24 hours after operation. Thirty-eight patients in the LTAP group and 35 patients in the UTAP group completed the study protocol. We found no significant difference in mean ± SD pain NRS during rest at 24 hours between the LTAP group (3.90 ± 1.7) and the UTAP group (4.5 ± 1.9). The mean difference in pain NRS during rest at 24 hours was 0.57 (95% CI -0.26 to 1.41). Because the lower boundary of a 95% CI for the differences in pain NRS was > -1, non-inferiority was established. There was no significant difference between the groups in NRS pain during rest, NRS pain on movement, and postoperative morphine consumption during the 48 hours after operation. These results show our new LTAP block technique was non-inferior to the ultrasound-guided technique in providing a TAP block after laparoscopic colorectal operation.

    Full Text Available Spontaneous rapture with consequent retroperitoneal hemorrhage (Wunderlich’s syndrome is the complication mostly feared from large renal angiomyolipomas (RAMLs. In hemodynamic stable patients, minimal invasive therapies have superseded open surgery as the mainstay of treatment, with contemporary cases mostly treated by selective arterial embolization. Robotic-assisted laparoscopic partial nephrectomy (RALPN is an established minimal access treatment that has been used in the past for benign and malignant lesions of the kidney in the elective setting, but rarely in urgent situations as primary treatment. We present a case of a ruptured RAML in a young female treated effectively by RALPN.

    Although most prostatectomy studies emphasize optimal nerve-sparing dissection planes, subtle technical variation also affects functional outcomes. The impact of minimizing assistant/surgeon tension on urinary function has not been quantified. We assess urinary function after attenuating neurovascular bundle (NVB) and rhabdosphincter tension during robotic-assisted radical prostatectomy (RARP). Retrospective study of prospectively collected data for 268 (RARP-T) versus 342 (RARP-0T) men with versus without tension on the NVB and rhabdosphincter during RARP. Outcomes compared include Expanded Prostate Cancer Index (EPIC) urinary function, estimated blood loss (EBL), operative time, and positive surgical margins (PSM). In unadjusted analysis, men undergoing RARP-T versus RARP-0T were older, had higher biopsy and pathologic Gleason grade, and higher preoperative prostate specific antigen (all p ≤ 0.023). Baseline urinary function was similar. Postoperatively, RARP-0T versus RARP-T was associated with higher 5-month urinary function scores (69.7 versus 64, p = 0.049). In adjusted analyses, RARP-0T versus RARP-T was associated with improved 5-month urinary function [Parameter Estimate (PE) 7.37, Standard Error (SE) 2.67, p = 0.006], while bilateral versus non-/unilateral nerve-sparing was associated with improved 12-month urinary function and continence (both p ≤ 0.035). RARP-0T versus RARP-T was associated with shorter operative times (PE 6.66, SE 1.90, p = 0.001) and higher EBL (PE 20.88, SE 6.49, p = 0.001). There were no significant differences in PSM. While the use of tension aids in dissection of anatomic planes, avoidance of NVB counter-traction and minimizing tension on the rhabdosphincter during apical dissection attenuates neuropraxia and leads to earlier urinary function recovery. Bilateral versus non-/unilateral nerve-sparing also improves urinary function recovery.

    Though initially slow to gain acceptance, the minimally invasive approach to pancreatic resection grew during the last decade and pancreatic operations such as the distal pancreatectomy and pancreatic enucleation are frequently performed laparoscopically. More complex operations such as the pancreaticoduodenectomy may also confer benefits with a minimally invasive approach but are less widely utilized. Though most research to date comparing open and laparoscopic pancreatectomy is retrospective, the current data suggest that compared with open, a laparoscopic procedure may afford postoperative benefits such as less blood loss, shorter hospital stay, and fewer wound complications. Regarding oncologic considerations, despite initial concerns, laparoscopic resection appears to be non-inferior to an open procedure in terms of lymph node retrieval, negative margin rates, and long-term survival. New technologies, such as robotics, are also gaining acceptance. Data show that while the laparoscopic approach incurs higher cost in the operating room, the resulting shorter hospital stay appears to be associated with an equivalent or lower overall cost. The minimally invasive approach to pancreatic resection can be safe and appropriate with significant patient benefits and oncologic non-inferiority based on existing data.

    Telerobotic surgery is the most advanced development in the field of minimally invasive surgery. The da Vinci surgical system, which is currently the most widely used telerobotic device, was approved by the Food and Drug Administration of the United States of America for clinical use in all abdominal operations in July 2000. The first da Vinci surgical system in China was installed in November 2005 at our institution. We herein report the first telerobotic-assisted laparoscopic abdominoperineal resection using the 3-arm da Vinci surgical system for low rectal cancer in Hong Kong and China, which was performed in August 2006. The operative time and blood loss were 240 min and 200 mL, respectively. There was no complication, and the patient was discharged on postoperative day five. An updated review of published literature on telerobotic-assisted colorectal surgery is included in this report, with special emphasis on its advantages and limitations.

    Objective: To evaluate the clinical feasibility and effect of the computer-assisted auto-frame navigation system for distal locking of tibial intrameduilary nails.Methods: The hardware components of the system included a PC computer with a monitor, auto mechanical stereotactical locating cubic frame, foot holder and localization operative apparatus. Special navigation software can be used for registration of X-ray fluoroscopic images and real-time controlling navigation of tools.Twenty-one cases of close tibial and fibular fractures were treated with closed intramedullary nailing, 6 of which involved in middle third, 12 in middle and lower third, 3 in lower third. C-arm alignment and registration time,fluoroscopic time and drilling time involved in the locking procedure were recorded. The size of unreamed or reamed tibial nails ranged from 8/300-11/330.Results: All distal holes except 1 were locked successfully. In 9 of 41 locked holes (21.95%), the drill bit touched the canal of locking hole without damage of the nail and clinical consequences. The fluoroscopy time per pair of screws was 2.23 s ± 0.31 s.Conclusions: The computer-assisted auto-frame navigation system for distal locking is well designed, easy to operate and do not need additional instruments during the procedure. The developed system enables the physician to precisely navigate surgical instruments throughout the anatomy using just a few computer-calibrated radiographic images. The total time of x-ray exposure per procedure can be significantly reduced.

    Artificial urinary sphincter (AUS) implantation is recommended for women suffering urinary stress incontinence. Robot-assisted laparoscopy allows improved dexterity and visibility compared to traditional laparoscopy, potentially providing significant advantages for deep pelvic surgery. To report our surgical technique and initial experience in transperitoneal robot-assisted laparoscopic AUS implantation in women with urinary stress incontinence. Eleven eligible patients with AUS implantation or revision using robot-assisted laparoscopy for urinary stress incontinence were included between January 2012 and February 2014 at Department of Urology, Lille University Hospital. Procedures were performed with the assistance of a four-arm da Vinci robot. The urethrovaginal space was dissected after transperitoneal access to the Retzius space. An 11-mm port placed in the right iliac fossa allowed introduction of the AUS device. The cuff and balloon tubes were externalised via a 5-mm suprapubic incision. The peritoneum was finally sutured. Clinical data were prospectively collected before, during, and after the procedure. Results were classified as complete continence (no leakage and no pad usage), social continence (leakage and/or pad usage with no impact on social life), or failure (leakage and/or pad usage impacting social life). After mean follow-up of 17.6 mo (interquartile range 10.8-26 mo), eight patients (72.7%) had a successful AUS implantation, of whom seven (87.5%) reported complete continence and one had social continence. Two vaginal injuries and two bladder injuries occurred intraoperatively. Two patients experienced early minor postoperative complications and two had a major postoperative complication. Robot-assisted laparoscopic AUS implantation is a feasible procedure. Further studies will better assess the place of robot-assisted laparoscopy in AUS implantation. We investigated the treatment of 11 patients with stress urinary incontinence using robot-assisted

    Shorter generation time and the power of genetic manipulation make mice an ideal model system to study bone biology as well as bone diseases. However their small size presents a challenge to perform strength measurements, particularly of the weight-bearing cancellous bone in the murine long bones. We recently developed an improved method to measure the axial compressive strength of the cancellous bone in the distal femur metaphysis in mice. Transverse micro-computed tomography image slices that are 7µm thick were used to locate the position where the epiphysis-metaphysis transition occurs. This enabled the removal of the distal femur epiphysis at the exact transition point exposing the full extent of metaphyseal trabecular bone, allowing more accurate and consistent measurement of its strength. When applied to a murine model system consisting of five month old male wild-type (WT) and Ca(2+)/calmodulin dependent protein kinase kinase 2 (CaMKK2) knockout (KO) Camkk2(-/-) mice that possess recorded differences in trabecular bone volume, data collected using this method showed good correlation between bone volume fraction and strength of trabecular bone. In combination with micro-computed tomography and histology, this method will provide a comprehensive and consistent assessment of the microarchitecture and tissue strength of the cancellous bone in murine mouse models.

    The short-term clinical results of the CLASICC trial indicated that clinical outcomes were similar between laparoscopic and open approaches. This study presents the short-term (3 month) cost analysis undertaken on a subset of patients entered into the CLASICC trial (682 of 794 patients). As expected the costs associated with the operation were higher in the 452 patients randomised to laparoscopic surgery (lap) compared with the 230 randomised to open procedure (open), £1703 vs £1386. This was partially offset by the other hospital (nontheatre) costs, which were lower in the lap group (£2930 vs £3176). The average cost to individuals for reoperations was higher in the lap group (£762 vs £553). Overall costs were slightly higher in the lap group (£6899 vs £6631), with mean difference of £268 (95%CI −689 to 1457). Sensitivity analysis made little difference to these results. The cost of rectal surgery was higher than for colon, for lap (£8259 vs £5586) and open procedures (£7820 vs £5503). The short-term cost analysis for the CLASICC trial indicates that the costs of either laparoscopic or open procedure were similar, lap surgery costing marginally more on average than open surgery.

    Hem-o-lok clips are widely used during robot-assisted and laparoscopic radical prostatectomy to control the lateral pedicles. There are a few reports of hem-o-lok clip migration into the bladder or vesico-urethral anastomosis and only four cases of hem-o-lok clip migration resulting into bladder neck contracture. Herein, we describe the first case, to our knowledge, of hem-o-lok clip migration leading to severe bladder neck contracture and subsequent stress urinary incontinence. A 62-year-old Caucasian man underwent robot-assisted laparoscopic radical prostatectomy for a T1c Gleason 8 prostate cancer. One month after surgery the patient was fully continent; however, three months later, he presented with acute urinary retention requiring suprapubic drainage. Urethroscopy showed a hem-o-lok clip strongly attached to the area between the vesico-urethral anastomosis and the urethral sphincter and a severe bladder neck contracture behind it. Following cold-knife urethral incision and clip removal, the bladder neck contracture was widely resected. At 3-month follow-up, the patient voided spontaneously with a peak flow rate of 9.5 ml/sec and absence of post-void residual urine, but leaked 240 ml urine at the 24-hour pad test. To date, at 1-year follow-up, his voiding situation remains unchanged. The present report provides further evidence for the risk of hem-o-lok clip migration causing bladder neck contracture, and is the first to demonstrate the potential of such complication to result into stress urinary incontinence.

    Full Text Available The recently developed minimally invasive techniques of ovariohysterectomy (OVH have been studied in dogs in order to optimize their benefits and decrease risks to the patients. The purpose of this study was to compare surgical time, complications and technical difficulties of transvaginal total-NOTES, single-port laparoscopic-assisted and conventional OVH in bitches. Twelve bitches were submitted to total-NOTES (NOTES group, while 13 underwent single-port laparoscopic-assisted (SPLA group and 15 were submitted to conventional OVH (OPEN group. Intra-operative period was divided into 7 stages: (1 access to abdominal cavity; (2 pneumoperitoneum; approach to the right (3 and left (4 ovarian pedicle and uterine body (5; (6 abdominal or vaginal synthesis, performed in 6 out of 12 patients of NOTES; (7 inoperative time. Overall and stages operative times, intra and postoperative complications and technical difficulties were compared among groups. Mean overall surgical time in NOTES (25.7±6.8 minutes and SPLA (23.1±4.0 minutes groups were shorter than in the OPEN group (34.0±6.4 minutes (P<0.05. The intraoperative stage that required the longest time was the approach to the uterine body in the NOTES group and abdominal and cutaneous sutures in the OPEN group. There was no difference regarding the rates of complications. Major complications included postoperative bleeding requiring reoperation in a bitch in the OPEN group, while minor complications included mild vaginal discharge in four patients in the NOTES group and seroma in three bitches in the SPLA group. In conclusion, total-NOTES and SPLA OVH were less time-consuming then conventional OVH in bitches. All techniques presented complications, which were properly managed.

    A 37-year-old man was referred for massive splenomegaly. In November 2005, he was diagnosed with non-Hodgkin's B-cell lymphoma in the setting of splenomegaly and thrombocytopenia. His laboratory results showed a coagulopathy owing to lupus anticoagulant. A computed tomography scan showed a 36 x 26 x 11 cm spleen and a prominent and sinuous splenic artery. The authors performed a laparoscopic splenectomy with an initial ligation of the splenic artery. The patient tolerated the procedure well and was discharged home on the fourth postoperative day in stable condition. Discussed in this paper is the safety and feasibility of the minimally invasive approach in massive splenomegaly.

    Full Text Available Percutaneous placement of gastrostomy was first described in 1980. Since then it has become widely used in pediatric surgery throughout the world. Inherent in the technique is the possibility of inadvertent damage to adjacent anatomical structures, most commonly the transverse colon. Management previously had involved laparotomy and correction of the gastrocolic fistula. Here we describe a novel laparoscopic approach to the repair of a gastrocolic fistula following percutaneous gastrostomy, avoiding the morbidity of laparotomy in an immunocompromised patient with a rotund abdomen secondary to steroid usage.

    Insulinomas are rare pancreatic neuroendocrine tumors that are most commonly benign,solitary,and intrapancreatic. Uncontrolled insulin overproduction from the tumor produces neurological and adrenergic symptoms of hypoglycemia. Biochemical diagnosis is confirmed by the presence of Whipple’s triad,along with corroborating measurements of blood glucose,insulin,proinsulin,C-peptide,β-hydroxybutyrate,and negative tests for hypoglycemic agents during a supervised fasting period. This is accompanied by accurate preoperative localization using both invasive and non-invasive imaging modalities. Following this,careful preoperative planning is required,with the ensuing procedure being preferably carried out laparoscopically. An integral part of the laparoscopic approach is the application of laparoscopic intraoperative ultrasound,which is indispensable for accurate intraoperative localization of the lesion in the pancreatic region. The extent of laparoscopic resection is dependent on preoperative and intraoperative findings,but most commonly involves tumor enucleation or distal pancreatectomy. When performed in an experienced surgical unit,laparoscopic resection is associated with minimal mortality and excellent long-term cure rates. Furthermore,this approach confers equivalent safety and efficacy rates to open resection,while improving cosmesis and reducing hospital stay. As such,laparoscopic resection should be considered in all cases of benign insulinoma where adequate surgical expertise is available.

    Objective To assess the feasibility, safety and efficacy of laparoscopic distal pancreatectomy (LDP) by comparing LDP with open distal pancreatectomy (ODP). Methods The clinical data of 68 patients with pancreatic body or tail diseases, who received distal pancreatectomy from May 2011 to February 2012, were retrospectively analyzed. LDP was performed in 16 cases and ODP in 52 cases. The baseline clinical data and the intraoperative and postoperative findings were compared between the two groups. Results There was no death in the two groups. The sex ratio, age, body mass index,tumor diameter and total hospital costs were not significantly different between the two groups. The incision length of LDP group was significantly shorter than that of ODP group ([3. 50 ± 1. 34] cm vs [17. 94 ± 2. 12] cm, P<0. 001). The operative duration of LDP group was significantly longer than that of ODP group ([145. 63 ± 56. 80] min vs [87. 21 ± 32. 06] min, P<0. 001). Postoperative hospital stay of LDP and ODP groups were (5. 06 ± 1. 24) d and (8. 06 ± 2. 53) d (P<0. 001) , time in bed after surgery were (1. 31 ± 0. 68) d and (2. 94 ± 0. 80) d (P<0. 001), and postoperative fasting time were (1. 31 ± 0. 57) d and (2.86 ± 1.34) d (P<0.001), respectively. Estimated blood loss of LDP and ODP groups were (318. 75 ± 227. 21) ml and (306.35 ± 378.36) ml (P=0. 898), respectively. Four patients had pancreatic leakages and 1 had peritoneal effusion in LDP group. Twelve patients had pancreatic leakages and 3 had peritoneal effusions in ODP group, with one having both pancreatic leakage and peritoneal effusion. There were no significant differences in the incidence of pancreatic leakage and peritoneal effusion between the two groups. The postoperative pain score was mainly 1-2 in LDP group and 2-3 in ODP group, with significant differences found between the two groups (P<0. 001). Conclusion LDP is feasible and safe in treating benign or borderline disease of pancreatic body and tail

    Full Text Available Robotic surgery is an option to laparoscopy that may offer some benefits including the possibility of performing surgery when the surgeon is geographically away from the patient and faster tireless repetitive movements with greater precision. At present, robot-assisted surgery has been done routinely in several institutions around the world, however, to the best of our knowledge, it is the first time such procedure is performed in our academic environment and herein is reported the first telerobotic-assisted laparoscopic cystectomy performed in a domestic pig at our institution using the Zeus®robotic system (Computer Motion, EUA. The procedure was performed using two different operating rooms geographically apart from each other. The assistant was in an operating room that was set with the operating table and the pig as well as with the Zeus® robotic arms. In the other operating room, the surgeon was seated in the control console with a three-dimensional imaging five meters away from the operating table connected with electric cables. The assistant surgeon established the pneumoperitoneum and five trocars were placed in a fan configuration. The surgeon started performing the surgery using three out of the five ports taking control of the laparoscope (voice control and manual control of laparoscopic instruments connected to the robotic arms using the joysticks. The other two ports were used by the assistant for traction and clips placement that was also necessary for exchanging the many laparoscopic instruments connected to the robot. The laparoscopic total cystectomy was successfully performed in 25 minutes with no complications. The truly benefits as well as the cost-effectiveness of the robotic surgery in our environment is yet to be determined after experience acquisition with telerobotic before start performing such procedures routinely in humans. The present report shows the technical feasibility of telerobotic surgery in a developing

    Whether surgeons perform better utilising a robot-assisted laparoscopic technique compared with an open approach during prostate cancer surgery is debatable. To report erectile function and early oncologic outcomes for both surgical modalities, stratified by prostate cancer risk grouping. In a prospective nonrandomised trial, we recruited 2545 men with prostate cancer from seven open (n=753) and seven robot-assisted (n=1792) Swedish centres (2008-2011). Clinometrically-validated questionnaire-based patient-reported erectile function was collected before, 3 mo, 12 mo, and 24 mo after surgery. Surgeon-reported degree of neurovascular-bundle preservation, pathologist-reported positive surgical margin (PSM) rates, and 2-yr prostate-specific antigen-relapse rates were measured. Among 1702 preoperatively potent men, we found enhanced erectile function recovery for low/intermediate-risk patients in the robot-assisted group at 3 mo. For patients with high-risk tumours, point estimates for erectile function recovery at 24 mo favoured the open surgery group. The degree of neurovascular bundle preservation and erectile function recovery were greater correlated for robot-assisted surgery. In pT2 tumours, 10% versus 17% PSM rates were observed for open and robot-assisted surgery, respectively; corresponding rates for pT3 tumours were 48% and 33%. These differences were associated with biochemical recurrence in pT3 but not pT2 disease. The study is limited by its nonrandomised design and relatively short follow-up. Earlier recovery of erectile function in the robot-assisted surgery group in lower-risk patients is counterbalanced by lower PSM rates for open surgeons in organ-confined disease; thus, both open and robotic surgeons need to consider this trade-off when determining the plane of surgical dissection. Robot-assisted surgery also facilitates easier identification of nerve preservation planes during radical prostatectomy as well as wider dissection for pT3 cases. For

    Full Text Available The da Vinci surgical robot has been shown to help shorten the learning curve for laparoscopic radical prostatectomy (LRP for both laparoscopically skilled and na surgeons[1,2]. This approach has shown equal or superior outcomes to conventional laparoscopic prostatectomy with regard to ease of learning, initial complication rates, conversion to open, blood loss, complications, continence, potency, and margin rates. Although the data are immature to compare oncologic and functional outcomes to open prostatectomy, preliminary data are promising.Herein, we review the technique and outcomes of robotic-assisted laparoscopic radical prostatectomy (RALP.

    Herein, we describe several steps to improve surgeon autonomy during a Left Robotic-Assisted Laparoscopic Radical Nephrectomy (RALRN), using the Da Vinci Si system. Our kidney cancer program is based on 2 community hospitals. We use the Da Vinci Si system. Access is obtained with the following trocars: Two 8 mm robotic, one 8 mm robotic, bariatric length (arm 3), 15 mm for the assistant and 12 mm for the camera. We use curved monopolar scissors in robotic arm 1, Bipolar Maryland in arm 2, Prograsp Forceps in arm 3, and we alternate throughout the surgery with EndoWrist clip appliers and the vessel sealer. Here, we described three steps and the use of 3 robotic instruments to improve surgeon autonomy. Step 1: the lower pole of the kidney was dissected and this was retracted upwards and laterally. This maneuver was performed using the 3rd robotic arm with the Prograsp Forceps. Step 2: the monopolar scissors was replaced (robotic arm 1) with the robotic EndoWrist clip applier, 10 mm Hem-o-Lok. The renal artery and vein were controlled and transected by the main surgeon. Step 3: the superior, posterolateral dissection and all bleeders were carefully coagulated by the surgeon with the EndoWrist one vessel sealer. We have now performed 15 RALRN following these steps. Our results were: blood loss 300 cc, console time 140 min, operating room time 200 min, anesthesia time 180 min, hospital stay 2.5 days, 1 incisional hernia, pathology: (13) RCC clear cell, (1) chromophobe and (1) papillary type 1. Tumor Stage: (5) T1b, (8) T2a, (2) T2b. We provide a concise, step-by-step technique for radical nephrectomy (RN) using the Da Vinci Si robotic system that may provide more autonomy to the surgeon, while maintaining surgical outcome equivalent to standard laparoscopic RN.

    During (robot-assisted) sentinel node (SN) biopsy procedures, intraoperative fluorescence imaging can be used to enhance radioguided SN excision. For this combined pre- and intraoperative SN identification was realized using the hybrid SN tracer, indocyanine green-(99m)Tc-nanocolloid. Combining this dedicated SN tracer with a lymphangiographic tracer such as fluorescein may further enhance the accuracy of SN biopsy. Clinical evaluation of a multispectral fluorescence guided surgery approach using the dedicated SN tracer ICG-(99m)Tc-nanocolloid, the lymphangiographic tracer fluorescein, and a commercially available fluorescence laparoscope. Pilot study in ten patients with prostate cancer. Following ICG-(99m)Tc-nanocolloid administration and preoperative lymphoscintigraphy and single-photon emission computed tomograpy imaging, the number and location of SNs were determined. Fluorescein was injected intraprostatically immediately after the patient was anesthetized. A multispectral fluorescence laparoscope was used intraoperatively to identify both fluorescent signatures. Multispectral fluorescence imaging during robot-assisted radical prostatectomy with extended pelvic lymph node dissection and SN biopsy. (1) Number and location of preoperatively identified SNs. (2) Number and location of SNs intraoperatively identified via ICG-(99m)Tc-nanocolloid imaging. (3) Rate of intraoperative lymphatic duct identification via fluorescein imaging. (4) Tumor status of excised (sentinel) lymph node(s). (5) Postoperative complications and follow-up. Near-infrared fluorescence imaging of ICG-(99m)Tc-nanocolloid visualized 85.3% of the SNs. In 8/10 patients, fluorescein imaging allowed bright and accurate identification of lymphatic ducts, although higher background staining and tracer washout were observed. The main limitation is the small patient population. Our findings indicate that a lymphangiographic tracer can provide additional information during SN biopsy based on ICG-(99m

    开腹胰体尾切除术术相比术中出血更少、术后恢复更快,具有明显微创优势。%Objective: To compare the peri-operative outcomes for laparoscopic distal pancreatectomy (LDP) and open distal pancreatectomy (ODP) for benign or premalignant pancreatic neoplasms in two institutions. Methods: This prospective comparative study included 91 consecutive patients who underwent LDP (n=45) or ODP (n=46) from Jan. 2010 to Dec. 2012. Demographics, intra-operative characteristics, and post-operative outcomes were compared. Results: The median operating time in the LDP group was (158.7±38.3) min compared with (92.2±24.1) min in the ODP group (P<0.001). Patients had lower blood loss in LDP than in the ODP ((122.6±61.1) ml vs. (203.1±84.8) ml,P<0.001). The rates of splenic conservation between the LDP and ODP groups were similar (53.3% vs. 47.8%,P=0.35). Al spleen-preserving distal pancreatectomies were conducted with vessel preservation. LDP also demonstrated better post-operative outcomes. The time to oral intake and normal daily activities was faster in the LDP group than in the ODP group ((1.6±0.5) d vs. (3.2±0.7) d,P<0.01; (1.8±0.4) d vs. (2.1±0.6) d,P=0.02, respectively), and the post- operative length of hospital stay in LDP was shorter than that in ODP ((7.9±3.8) d vs. (11.9±5.8) d,P=0.006). No difference in tumor size ((4.7±3.2) cm vs. (4.5±1.8) cm,P=0.77) or overal pancreatic fistula rate (15.6% vs. 19.6%, P=0.62) was found between the groups, while the overall post-operative complication rate was lower in the LDP group (26.7% vs. 47.8%,P=0.04). Conclusions: LDP is safe and effective for benign or premalignant pancreatic neoplasms, featuring lower blood loss and substantialy faster recovery.

    The role of a cystogram to assess the vesico-urethral anastomosis (VUA) after robot-assisted laparoscopic radical prostatectomy (RARP) has been debated. Early catheter removal without cystogram was reported to be associated with a trend towards an increased risk of acute urinary retention (AUR). In two cohorts we studied the effects of VUA leakage on cystogram and functional outcome after RARP. Cohort A contained 1390 consecutive men that routinely underwent a cystogram after RARP. Transurethral catheter (TUC) was removed in the absence of VUA leakage or minimal leakage on subsequent repeat cystogram. Outcome was compared to a group of 120 men that underwent cystography 7-10 days after RARP but had the TUC removed independent of cystography findings (cohort B). Outcome was assessed by early clinical follow-up and quality of life (QOL) questionnaires at 6 months. Men in cohort B had an increased risk of AUR and 6 months voiding complaints when compared to cohort A. The incidence of AUR and voiding complaints was associated with grade 2-3 leakage on cystography in cohort B but not in cohort A. Grade 2-3 leakage on cystogram was more likely in men with larger prostates larger and preoperative voiding complaints. Selective cystogram in men with larger prostates and preoperative lower urinary tract symptoms (LUTS) may prevent early AUR and voiding complaints after RARP when prolonged TUC use is applied.

    Neoadjuvant imatinib for gastrointestinal stromal tumours (GISTs) is increasingly used nowadays. As oesophagectomy is associated with high morbidity and mortality, a preoperative downsizing of an oesophageal GIST to limit the extent of resection would be ideal. Because these tumours are rare and neoadjuvant treatment with imatinib is recent, there is limited literature available regarding neoadjuvant administration of imatinib in patients with oesophageal GISTs. A 50-year-old woman presented with total dysphagia. An upper endoscopy and biopsy revealed a large submucosal KIT-positive GIST obstructing the mid oesophagus. CT confirmed a lesion measuring 99 mm × 50 mm × 104 mm. Because the size and location of the tumour increased the risk of intraoperative rupture, it was decided to administer preoperative imatinib. The patient had an excellent clinical and radiological response. Her dysphagia gradually resolved and the follow-up CT scans of the first 10 months showed a gradually reducing tumour size to 54 mm × 33 mm × 42 mm. The patient underwent an uneventful laparoscopic-assisted Ivor-Lewis oesophagectomy. Postoperatively, the patient continued with adjuvant imatinib. At the last follow-up, 1 year from operation and 38 months from the diagnosis, the patient is disease free.

    Distal clavicle marrow edema: frequency, MRI in the early stage and macroscopic correlation to the bone marrow distribution and to evaluate frequency and diagnostic criteria of a posttraumatic clavicula disorder with an edema pattern on MRI. An additional macroscopic study of the clavicle should elucidate anatomic pecularities which could explain the reaction of the distal clavicle. 285 MRI of traumatized patients were analyzed for edema pattern of the distal clavicle. Pattern A edema within the clavicle and the acromion was distinguished from pattern B edema within the clavicle only. Dissection in 20 cadavers should reveal vascular pecularities and the bone marrow distribution within clavicle and acromion or vascular pecularities. In 38 patients (13,3%) we found edema within the distal clavicle. Pattern A was found in 28 (9,8%) and pattern B in 10 patients (3,5%). Pattern A was usually associated with swelling of the AC joint (27 out of 28). Other injuries were not evident. 18 cadavers showed hematopoetic marrow within the distal clavicle and fatty marrow within the acromion. The distale clavicle can frequently react with edema pattern after trauma without evidence for another injury. Distinguish in cases with and cases without synovitis of the AC joint could have impact on therapy. A peculier vascular supply of the distal clavicle could not be found. (orig.)

    Full Text Available ABSTRACT : BACKGROUND: There has been a rapid worldwide adoption of laparoscopic procedures across many surgical specialt ies, most notably in Gynaecology. Unfortunately, the increased adoption of laparoscopic surgery has also been accompanied by a corresponding rise in the rates and types of complications reported. AIMS : To audit the different types of laparoscopic surgerie s and their complications and comparison with other routes of surgery. METHODS & MATERIALS : We have retrospectively analysed 285 laparoscopic surgeries and 306 other routes of surgery which were done at our institute from July 2011 to April 2013.We admit t he patients 1 - 2 days prior to surgery and a complete medical work - up of the patient is done for elective laparoscopic surgery .We defer laparoscopy for malignant conditions, uterine size more than 20 weeks, cervix flushed to the vagina or with history of m ore than 2 pelvic surgeries. Sub - fertile women, after an initial workup, are subjected to diagnostic laparoscopy with chromopertubation. For laparoscopic cystectomies, patients with ultrasono graphy findings suggestive of benign tumours are selected. RESULT S : We have performed 285 laparoscopic procedures over this time period till date. Majority of these cases are Laparoscopic Assisted Vaginal Hysterectomies (LAVH [111 – 38.9%], followed by laparoscopic surgeries for various benign ovarian conditions ( BOC [62 – 21%] and Diagnostic Laparoscopies ( DL with or without laparoscopic ovarian drilling ( LOD [59 cases – 20.7%]. Out of 111 LAVH, 3 patients had bladder injury [2.7%] ; Out of 285 cases that underwent laparoscopic procedures, 5 [1.75%] required conversi on to laparotomy. Overall operative complications including major and minor, are significantly higher in the abdominal surgery group as compared to the laparoscopic group ( p value= 0.001 CONCLUSION : Laparoscopy is a safe route for conventional surgery, with lesser intraoperative, immediate post

    Perioperative intravenous (IV) infusion of lidocaine has been shown to decrease post-operative pain, shorten time to return of bowel function, and reduce the length of hospital stay. This randomized, prospective, double-blinded, placebo-controlled clinical trial evaluated the impact of IV lidocaine on the quality of post-operative analgesia and other outcomes after hand-assisted laparoscopic colon surgery. Sixty four patients with colon cancer scheduled for elective colon resection were involved in this study. Patients were randomized to receive either lidocaine infusion [lidocaine group (LG)] or normal 0.9 % saline infusion [placebo group (PG)] for a period of 24 h. Anaesthetic and surgical techniques were standardized. Twenty-four-hour post-operative analgesia in the recovery area was maintained by continuous infusion of 0.1 μg/kg/h fentanyl. The primary outcome of the study was post-operative pain control. Pain was assessed using visual analogue scale (VAS) scores at 2, 4, 8, 12, and 24 h after surgery. Patients with a VAS score >3 were treated with ketorolac 30 mg as needed. Secondary outcomes included time to resumption of bowel function and length of hospital stay. Data in the two groups were compared using the two-tailed Student's t test. All statistical tests were two-tailed at a significance level of 0.05. Demographic characteristics and clinical features of both groups were similar. Intensity of pain at rest in LG compared with PG was significantly lower during the first 24 h post-operatively. LG patients reported significantly less pain during movements at 2-, 12-, and 24-h post-surgery than PG patients. The study showed that ketorolac consumption was significantly higher in PG: mean ketorolac consumption in LG was 43.77 ± 13.86 mg and in PG 51.67 ± 13.16 mg (p = 0.047). Compared with placebo, lidocaine infusion produced a 32 % reduction in time to the first drink (Cohen's d = 3.85), 16 % reduction in time to the first full diet

    This thesis contains four studies all focusing on women with endometrial cancer undergoing robotic-assisted laparoscopic hysterectomy (RALH). Women with endometrial cancer are typically elderly with co-morbidities. RALH is a relatively new treatment option which has been introduced and adopted over the last decade without randomised controlled trials (RCTs) to prove superiority over other surgical alternatives. The purpose of the thesis was to explore and describe patient and health economic outcomes of RALH for women with endometrial cancer using different research approaches. The first study was a retrospective descriptive cohort study with 235 women. The aim was to explore types and incidence of post-operative complications within 12 months after RALH reported with the Clavien-Dindo scale. We found that 6% had severe complications and that women with lymphadenectomy did not have an increased rate of complications. Urinary tract and port site infections were the most frequent complications. The second study was a qualitative interview study where we explored the experience of undergoing RALH. Using content analysis, we analysed semi-structured interviews with 12 women who had undergone RALH on average 12 weeks earlier. The women were positive towards the robotic approach and felt recovered shortly after. They expressed uncertainty with the normal course of bleeding and bowel movement post-operatively as well as with the new anatomy. The third study was an economic evaluation; an activity-based costing study including 360 women comparing total abdominal hysterectomy (TAH) to RALH. This study showed that for women with endometrial cancer, RALH was cheaper compared to TAH, mainly due to fewer complications and shorter length of stay (LOS) that counterbalanced the higher robotic expenses. When including all cost drivers the analysis showed that the RALH procedure was more than 9.000 Danish kroner (DKK) cheaper than the TAH. Increased age and Type 2 diabetes appeared

    To analyze the learning curve for cancer control from an initial 250cases(GroupI) and subsequent 250cases(GroupII) of robotic‑assisted laparoscopic radical prostatectomy(RALP) performed by a single surgeon. Five hundred consecutive patients with clinically localized prostate cancer received RALP and were evaluated. Surgical parameters and perioperative complications were compared between the groups. Positive surgical margin(PSM) and biochemical recurrence(BCR) were assessed as cancer control outcomes. Patients in GroupII had signiifcantly more advanced prostate cancer than those in GroupI(22.2%vs 14.2%, respectively, with Gleason score 8–10,P=0.033; 12.8%vs 5.6%, respectively, with clinical stage T3,P=0.017). The incidence of PSM in pT3 was decreased signiifcantly from 49% in GroupI to 32.6% in GroupII. Ameaningful trend was noted for a decreasing PSM rate with each consecutive group of 50cases, including pT3 and high‑risk patients. Neurovascular bundle(NVB) preservation was signiifcantly inlfuenced by the PSM in high‑risk patients(84.1% in the preservation groupvs 43.9% in the nonpreservation group). The 3‑year, 5‑year, and 7‑year BCR‑free survival rates were 79.2%, 75.3%, and 70.2%, respectively. In conclusion, the incidence of PSM in pT3 was decreased signiifcantly after 250cases. There was a trend in the surgical learning curve for decreasing PSM with each group of 50cases. NVB preservation during RALP for the high‑risk group is not suggested due to increasing PSM.

    We sought to evaluate the effectiveness of the American Urological Association (AUA) antibiotic prophylaxis guidelines in patients undergoing robot-assisted laparoscopic radical prostatectomy (RALP). Our prospective registry database was reviewed for all RALP cases. The following variables were evaluated: age, associated comorbidities, body mass index (BMI), total operative time, length of stay (LOS), prostate weight, pathological grade and stage. Until 11/2011, RALP patients were treated with antibiotics administered in the operating room and continued until urethral catheter removal. Since 11/2011, all patients were treated with a single intravenous dose of Cephalosporin and Aminoglycoside given within 30 min of surgical incision. The rate of catheter-associated urinary tract infection (CAUTI) was evaluated in both groups. 229 RALP patients were identified. The first 60 patients (26.2%) were treated according to the old protocol (Group 1) while the remaining 169 (73.8%) were treated according to the new protocol (Group 2). Group match was identified in all categories but LOS. Moreover, LOS was found to be longer in Group 1 compared with Group 2 (5.8 vs. 4.5 days, p < 0.001). CAUTI rate was similar in both groups (8.3 vs. 8.9%, respectively, p = 0.89). Logistic regression analysis did not demonstrate any association between treatment protocol and potential risk for CAUTI. Therefore, a single preoperative dose of antibiotics does not increase the rate of CAUTI following RALP compared with prolonged antibiotic treatment. Moreover, it was found to be associated with shorter LOS. Complying with the AUA guidelines may reduce morbidity and medical costs.

    This study reports an early, single-institution experience of combined thoracoscopic and laparoscopic robotic-assisted minimally invasive esophagectomy (RAMIE) using a four-arm robotic platform, with special attention given to the pitfalls and complications during procedure development. We conducted a prospective, single-cohort, observational study of patients undergoing RAMIE at a single institution. A total of 21 patients (median age, 62 years [range, 37-83 years]) underwent RAMIE with a four-arm robotic platform (17 by Ivor Lewis and 4 by McKeown). Of the patients, 17 (81%) had a complete (R0) resection, and 16 (76%) received induction treatment, the majority (14/21 [67%]) with combined chemoradiation. The median operative time was 556 min (range, 395-807 min), which decreased to 414 min (range, 405-543 min) for the last 5 cases in the series. The median estimated blood loss was 307 cm(3) (range, 200-500 cm(3)), and the median length of hospital stay was 10 days (range, 7-70 days). The median number of lymph nodes resected was 20 (range, 10-49). Five (24%) patients were converted to open procedures. Five patients (24%) had major complications. One (5%) died of complications on postoperative Day 70, and 3 (14%) had clinically significant anastomotic leaks (Grade II or greater, by Common Terminology Criteria for Adverse Events version 3.0). Three patients (14%) in this early experience developed airway fistulas. While four-arm RAMIE may offer advantages over standard minimally invasive esophagectomy approaches, its adoption in a structured program, with critical evaluation of adverse events and subsequent adjustment of technique, is paramount to maximize patient safety, minimize complications and improve the conduct of operation early in the learning curve. Particular technical consideration should be given to prevention of airway complications.

    There remains equipoise with regard to whether laparoscopic radical prostatectomy (LRP) or robot-assisted radical prostatectomy (RARP) has any benefit over the other. Despite this, there is a trend for the increasing adoption of RARP at great cost to health services across the world. The aim was to critically analyze the learning curve and outcomes for LRP and RARP for two experience- and volume-matched surgeons who have completed the learning curve for LRP and RARP. Two experience- and volume-matched LRP and RARP surgeons who have completed the learning curve were compared with respect to their learning curve and outcomes for RARP and LRP. There were 531 RARP and 550 LRPs analyzed from April 2003 until January 2012 at two relatively high-volume United Kingdom centers. Outcome measures included operative time, blood loss, complication rate (Clavien-Dindo grade III), positive surgical margin (PSM) rate, and early continence rate. Learning curves for blood loss, operative times, and complication rate were similar between groups. The overall PSM rate and pT2 PSM rate learning curves were longer for RARP compared with LRP but shorter for early continence. Apical PSM showed no learning curve for RARP; however, a long learning curve for LRP and the rate was lower for RARP than for LRP (P=learning curves. Despite the long learning curve for RARP, significant benefits in lower PSM rates and better early continence in comparison with LRP exist. There are benefits to patients with RARP over LRP, especially those linked to better apical dissection (apical PSM and early continence).

    Full Text Available Introduction: The aim of this study was to assess the outcomes of early vascular release in robot-assisted laparoscopic partial nephrectomy (RAPN to reduce warm ischaemia time (WIT and minimise renal dysfunction. RAPN is increasingly utilised in the management of small renal masses. To this end it is imperative that WIT is kept to a minimum to maintain renal function. Methods: RAPN was performed via a four-arm robotic transperitoneal approach. The renal artery and vein were individually clamped with robotic vascular bulldog clamps to allow cold scissor excision of the tumour. The cut surface was then sutured with one or two running 3-0 V-LocTM sutures, following which the vascular clamps were released. Specific bleeding vessels were then selectively oversewn and the collecting system repaired. Renorrhaphy was then completed using a running horizontal mattress 0-0 V-LocTM suture. Results: A total of 16 patients underwent RAPN with a median WIT of 15 minutes (range: 8-25, operative time 230 minutes (range: 180-280 and blood loss of 100 mL (range: 50-1000. There were no transfusions, secondary haemorrhages or urine leaks. There was one focal positive margin in a central 5.5 cm pT3a renal cell carcinomas (RCC. Long-term estimated glomerular filtration rate (eGFR was not significantly different to pre-operative values. Conclusion: In this patient series, early vascular release effectively minimised WIT and maintained renal function without compromising perioperative safety.

    Comparison of surgical results on obese patients undergoing hysterectomy by robot-assisted laparoscopy or laparotomy. University hospital. All women (n=114) with a BMI ≥30 kg/m(2) who underwent a simple hysterectomy as the main surgical procedure between November 2005 and November 2009 were identified. Robot-assisted procedures (n=50) were separated into an early (learning phase) and a late (consolidated phase) group; open hysterectomy was considered an established method. Relevant data was retrieved from prospective protocols (robot) or from computerized patient charts (laparotomy) until 12 months after surgery. Complications leading to prolonged hospital stay, readmission/reoperation, intravenous antibiotic treatment or blood transfusion were considered significant. The surgical technique used for morbidly obese patients is described. Women in the late robot group (n=25) had shorter inpatient time (1.6 compared to 3.8 days, plaparoscopic hysterectomy in a consolidated phase in obese women is associated with shorter hospital stay, less bleeding and fewer complications compared to laparotomy but, apart from women with BMI ≥35, a longer operative time. © 2011 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2011 Nordic Federation of Societies of Obstetrics and Gynecology.

    Robot-assisted laparoscopic prostatectomy is increasingly used compared with a standard laparoscopic technique, but it remains uncertain whether potential benefits offset higher costs. To determine the cost-effectiveness of robotic prostatectomy. We conducted a care pathway description and model-based cost-utility analysis. We studied men with localised prostate cancer able to undergo either robotic or laparoscopic prostatectomy for cure. We used data from a meta-analysis, other published literature, and costs from the UK National Health Service and commercial sources. Care received by men for 10 yr following radical prostatectomy was modelled. Clinical events, their effect on quality of life, and associated costs were synthesised assuming 200 procedures were performed annually. Over 10 yr, robotic prostatectomy was on average (95% confidence interval [CI]) £1412 (€1595) (£1304 [€1473] to £1516 [€1713]) more costly than laparoscopic prostatectomy but more effective with mean (95% CI) gain in quality-adjusted life-years (QALYs) of 0.08 (0.01-0.15). The incremental cost-effectiveness ratio (ICER) was £18 329 (€20 708) with an 80% probability that robotic prostatectomy was cost effective at a threshold of £30 000 (€33 894)/QALY. The ICER was sensitive to the throughput of cases and the relative positive margin rate favouring robotic prostatectomy. Higher costs of robotic prostatectomy may be offset by modest health gain resulting from lower risk of early harms and positive margin, provided >150 cases are performed each year. Considerable uncertainty persists in the absence of directly comparative randomised data. Copyright © 2013 European Association of Urology. Published by Elsevier B.V. All rights reserved.

    Objective To investigate the techniques of robotic-assisted laparoscopic hysterectomy. Methods With the patients at dorsal lithotomy position, under general anesthesia, we placed a colpotomy ring and uterine manipulator to delineate the vaginal fornices, and then inserted a colpo-pneumo occluder. With an digital video system prepared, we determined one port for camera, and two ports for instrument arms, and one port for assistant trocars. A patient cart was positioned between the patient' s legs and locked, the camera arm and remained instrument arms were then docked, HotShears (Monopolar Curved Scissors) and PK Dissect Forceps were fixed at each side. When suturing, needle drivers was used at the both sides. Assistant trocar was used to help exposing surgical field and suction. By controlling the robotic arms, we completed the operation. Results The mean operation time was (82.5 ± 9.5) minutes [ console time (61.9 ± 7.9) minutes, docking time (7.0 ± 1.5 ) minutes ]; and intraoperative blood loss was (55.0 ± 12.8) ml.

    Full Text Available INTRODUCTION: We describe our experience with hand-assisted laparoscopy (HAL as an option for the treatment of large renal specimens. MATERIALS AND METHODS: Between March 2000 and August 2004, 13 patients candidate to nephrectomies due to benign renal conditions with kidneys larger than 20 cm were included in a prospective protocol. Unilateral nephrectomy was performed in cases of hydronephrosis (6 patients or giant pyonephrosis (4 patients. Bilateral nephrectomy was performed in 3 patients with adult polycystic kidney disease (APKD with low back pain refractory to clinical treatment previous to kidney transplant. The technique included the introduction of 2 to 3 10 mm ports, manual incision to allow enough space for the surgeon's wrist without a commercial device to keep the pneumoperitoneum. The kidney was empty, preferably extracorporeally, enough to be removed through manual incision. We have assessed operative times, transfusions, complications, conversions, hospital stay and convalescence. RESULTS: The patients mean age (9 women and 4 men was 58 years. Mean operating time was 120 ± 10 min (hydronephrosis, 160 ± 28 min (pyonephrosis and 190 ± 13 min (bilateral surgery for APKD. There was a need for a conversion in 1 case and another patient needed a transfusion due to a lesion in the renal vein; 2 patients had minor complications. CONCLUSION: HAL surgery is a minimally invasive alternative in the treatment of large renal specimens, with or without significant inflammation.

    Laparoscopy-assisted proximal gastrectomy (LAPG) with esophagogastrostomy using a novel "open-door" technique was introduced recently, with the aim of preventing gastroesophageal reflux. However, quantitate assessment of gastroesophageal reflux after this surgery has not been performed till date. The aims of the current study were to investigate the safety and feasibility of this operation and to elucidate the postoperative reflux status. Twenty consecutive patients (18 men) with (y)cStage I gastric cancer in the upper third of the stomach who underwent LAPG at Kitasato University Hospital from May 2015 through September 2016 were retrospectively reviewed. We performed 24-h impedance-pH monitoring 3 months after surgery for the first eight patients and analyzed the postoperative reflux status. Median operation time was 333 min, while median anastomotic time was 81 min. None of the 20 patients experienced anastomotic leakage while two patients experienced anastomotic stricture requiring endoscopic balloon dilatation. No patient experienced heartburn without antacid drugs. During the 24-h impedance-pH monitoring, all but one patient had normal gastroesophageal acid reflux with the acid percent time of technique is a safe and feasible procedure for LAPG. The degree of gastroesophageal reflux was acceptable using this technique. Randomized controlled trials with long-term follow-ups are required to confirm that this technique would be superior to the others.

    melhores resultados.Two groups of dogs, GA (n=8 and GL (n=16 were used to compare the conventional and the transparietal laparsocopic assisted technique for colopexy and to compare with the conventional surgery. In the GA group, the colopexy was proceded by incisional technique trough celiotomy. In the GL group, the colopexy was performed using the transparietal laparoscopic assisted technique. The GL dogs were separated in four subgroups (S1, S2, S3 and S4 with four dogs each. In each subgroup a different stent was used, capton of infusion tube (S1; plastic disks made with NaCl solutions bottles (S2; disks made with rubber (S3 and silicone disks (S4. The time for complete surgery was statically higher in the GL group than GA. Seven GA dogs maintained the colopexy and all of these presented adherences of the omentum in the suture zone. In three GL animals, all of the S4 subgroup the colopexies were not maintained. In all dogs of this subgroup dermatitis and/or cellulites were observed. Best results were obtained in the S3 subgroup dogs. The main histological observations in the 14d-after surgery biopsies in GL animals were related to a higher connective tissue deposition at the colon adherence, and infiltration of this type of tissue into the associated musculature. In the 28d biopsies, no difference was found between groups. In both groups, the collagen fibers presented mature aspect. Concluding, the transparietal laparoscopic assisted technique is viable, however it’s associated with tissue lesions in the regions in contact with the material used to support the suture. The rubber disk presented better results.

    The impact of nerve sparing (NS) on urinary continence recovery after robot-assisted laparoscopic radical prostatectomy (RALP) has yet to be defined. To evaluate the effect of a risk-stratified grade of NS technique on early return of urinary continence. Data were collected from 1546 patients who underwent RALP by a single surgeon at a tertiary care center from December 2008 to October 2011. Patients were categorized preoperatively by a risk-stratified approach into risk grades 1-4, with risk grade 1 patients more likely to receive NS grade 1 or complete hammock preservation. This categorization was also conducted for risk grades 2-4, with grade 4 patients receiving a non-NS procedure. Risk-stratified grading of NS RALP. Univariate and multivariate analysis identified predictors of early return of urinary continence, defined as no pad use at ≤ 12 wk postoperatively. Early return of continence was achieved by 791 of 1417 men (55.8%); of those, 199 of 277 (71.8%) were in NS grade 1, 440 of 805 (54.7%) were in NS grade 2, 132 of 289 (45.7%) were in NS grade 3, and 20 of 46 (43.5%) were in NS grade 4 (preturn of urinary continence when NS grade 1 was the reference variable compared with NS grade 2 (preturn of urinary continence. Positive surgical margin rates were 7.2% (20 of 277) of grade 1 cases, 7.6% (61 of 805) of grade 2 cases, 7.6% (22 of 289) of grade 3 cases, and 17.4% (8 of 46) of grade 4 cases (p=0.111). Extraprostatic extension occurred in 6.1% (17 of 277) of NS grade 1 cases, 17.5% (141 of 805) of NS grade 2 cases, 42.5% (123 of 289) of NS grade 3 cases, and 63% (29 of 46) of NS grade 4 cases (prisk-stratified grade of NS technique and early return of urinary continence as patients with a lower grade (higher degree) of NS achieved an early return of urinary continence without compromising oncologic safety.

    We report our results and short term follow up of transperitoneal laparoscopic pyeloplasty for pelvi-ureteric junction (PUJ) obstruction. We have prospectively maintained a database to document our initial experience of 54 laparoscopic pyeloplasty. All procedures were carried out by one surgeon through a transperitoneal approach. The data extends from April 2005 to September 2008 and reports operative time, blood loss, complications, hospital stay, short term follow-up on symptomatic and radiological outcome. Fifty-four procedures were performed during the study period. Mean patient age was 29 years. Mean operating time was 133 minutes (range 65-300 minutes), and mean blood loss was 45 ml (range 20-300 ml). No intra operative complication occurred. Neither blood transfusion nor conversion to open surgery was required. Postoperative mean hospital stay was 3.4 days (range 3-14 days). There were 3 anastomotic leakages; 2 in the immediate postoperative period and 1 following removal of stent. They all required percutaneous drainage and prolonged stenting. Overall 47 (87%) patients have symptomatic relief and resolution of obstruction on renogram. Four (7%) patients developed recurrence. Three (5.5%) patients had symptomatic relief but have a persistent obstructive renogram. Laparoscopic pyeloplasty is an effective alternative treatment for symptomatic pelvi-ureteric junction obstruction. The results appear comparable to open pyeloplasty with decreased postoperative morbidity.

    Laparoscope manipulating robots are useful for maintaining a stable view during a laparoscopic operation and as a substitute for the surgeon who controls the laparoscope. However, there are several problems to be solved. A large apparatus sometimes interferes with the surgeon. The setting and repositioning is awkward. Furthermore, the initial and maintenance costs are expensive. This study was designed to develop a new laparoscope manipulating robot to overcome those problems. We developed a compact robot applicable for various types of laparoscopic surgery with less expensive materials. The robot was evaluated by performing an in vitro laparoscopic cholecystectomy using extracted swine organs. Then, the availability of the robot to various operations was validated by performing a laparoscopic cholecystectomy, anterior resection of the rectum, and distal gastrectomy using a living swine. The reliability of the system was tested by long-time continuous running. A compact and lightweight laparoscope manipulating robot by the name of P-arm was developed. The surgical time of an in vitro laparoscopic cholecystectomy with and without the P-arm was not different. The three types of operations were accomplished successfully. During the entire procedure, the P-arm worked without trouble and did not interfere with the surgeons. Continuous 8-h operating tests were performed three times and neither discontinuance nor trouble occurred with the system. The P-arm worked steadily for various swine operations, without interfering with surgeon's work.

  1. Laparoscopic Techniques: What is the Role in Inflammatory Bowel Disease?

    Directory of Open Access Journals (Sweden)

    1995-01-01

    Full Text Available Laparoscopic cholecystectomy has quickly become the preferred technique for removing the gallbladder. Real advantages in the area of laparoscopic gallbladder removal have spurred interest towards other areas of laparoscopic surgery. There has been interest in laparoscopic bowel surgery but this approach has not gained popularity as quickly as gallbladder surgery. Reasons surround the fact that the bowel is a continuous organ (versus an end organ like the gallbladder laden with bacteria and it has a rich blood supply. These differences make laparoscopic bowel surgery more difficult and challenging. If inflammatory bowel disease (IBD is considered, the indications to approach surgery laparoscopically fall into two categories: current and future indications. The current indications are diagnostic laparoscopy, fecal diversion, limited bowel resections with extracorporeal anastomosis and stoma closures. Future indications include laparoscopic subtotal colectomy and laparoscopic assisted pelvic pouch procedures. As experience is gained and laparoscopic instruments are modified and refined for bowel surgery, intracorporeal anastomosis and more extensive bowel resections will be feasible. Currently laparoscopic bowel surgery can be done in select circumstances for problems associated with IBD. It has yet to be proven if doing the surgery laparoscopically provides advantages for bowel surgery as has been demonstrated with gallbladder surgery. Prospective studies are underway to answer these questions.

    Full Text Available PURPOSE: Evaluate the initial experience of laparoscopic ureteral reimplant for ureteral stenosis. MATERIALS AND METHODS: From January 2004 to June 2008, 10 patients underwent 11 laparoscopic reconstruction surgeries for ureteral stenosis. Seven cases of stenosis of the distal ureter, two at the level of iliac vessels, a case of bilateral distal stenosis and one in the medium third. Eight ureteroneocystotomies were performed by extravesical technique with anti-reflux mechanism, two cases of vesical reimplant with Boari technique and one case using the psoas hitch technique. RESULTS: The average surgical time was 166 minutes (115-245 min, mean blood loss was 162 mL (100-210 mL and the average hospital stay was 2.9 days (2-4 days. There were two complications: a lesion of the sigmoid colon identified peroperatively and treated with laparoscopic sutures with good evolution, and a case of ureteral stone obstruction at the 30th day postoperative, treated by laser ureterolitotripsy. All patients had resolution of the stenosis at an average follow-up period of 18 months (3-54 months.

    AIM: To explore the clinical effects of laparo-scopic ultrasound imaging technique in robot-assisted abdominal surgery. METHODS: Twenty-eight patients (including three with intrahepatic bile duct stones, three with calculous cholecystitis, eight with hepatic tumor, seven with hilar cholangiocarcinoma, four with pancreatic tumor, and three with hypersplenism) who underwent laparoscopic ultrasound-guided robot-assisted abdominal surgery in our hospital were included in our study. Laparoscopic ultrasound was used to determine the location of lesions and their relation with nearby tissue, choose the optimal surgical method, guide the pathway and evaluate the effects during surgery. The clinical effects were evaluated by ultrasound, contrast-enhanced CT, MRCP and biochemical assays after surgery. RESULTS: All surgical procedures were performed successfully, and no serious intraopera-tive or postoperative complications occurred. Biochemical parameters returned or approached -to normal levels. In RFA regions, color Doppler ultrasound imaging showed no color signal and contrast-enhanced CT showed no enhancement. Ultrasonography, CT or MRCP detected no abnormity in the bile duct. The volume of the entire spleen and damaged part of the spleen from RFA regions were measured by enhanced CT, and the percentages of damaged part of the spleen were 43%, 45% and 49%. CONCLUSION: Laparoscopic ultrasound can not only determine the lesion and guide the operative route but also help surgeons to select the operative strategy. With the development of robot-assisted surgical system, laparoscopic ultrasound will become an indispensable part of this surgery.%目的:探讨腹腔镜超声影像技术引导机器人辅助腹部手术的临床应用效果.方法:对28例患者(肝内胆管结石3例,结石性胆囊炎3例,肝占位8例,肝门部胆管癌7例,胰腺占位4例,脾功能亢进3例)实施腹腔镜超声引导机器人辅助腹部手术治疗,手术过程中应用腹腔镜超声探

    Full Text Available Background: Although Laparoscopy is becoming a standard procedure in management of pediatric urology disorders, but its widespread use still limited. This can be attributed mainly to difficulty in acquiring such specialized technique, especially by post graduate practicing urologist. Thus, we herein evaluate the impact of condensed laparoscopic training programme in children hospital with the aim to analyze the feasibility and safety of laparoscopic orchidopexy in training basic laparoscopic skills. The aim of this study was to review experience as a mentor in training laparoscopic skills through condensed training programme based on high volume low risk procedure of pediatric laparoscopic orchidopexy. Materials and Methods: In order to implement a condensed laparoscopic curriculum in a short period of time while maintaining utmost patient safety, laparoscopic orchidopexy was used as the technique of choice. The course was conducted over a period of 5 days starting from 1 st November 2010 in a tertiary pediatric surgical center under guidance of an expert mentor. A total of 30 testicular units in 27 pediatric patients of different age group diagnosed with impalpable undescended testis underwent laparoscopic intervention. The course was conducted in three stages with the aim to deliver laparoscopic skills to trainee. In stage one out of eight cases operated by mentor with assistance of trainee six were operated on day 1 and two cases were operated on second day. The trainee performed 12 cases of laparoscopy independently with assistance of mentor in stage two which was carried out on day 2, 3 and 4. Finally all 7 cases including two second stage laparoscopic orchidopexy procedures were carried out independently by trainee under observer ship of mentor in stage three during day 4 and 5 of training programme. The feasibility and efficacy of laparoscopic orchidopexy in training laparoscopic skills through condensed training programme was assessed

    Objective. To investigate the indications, surgical techniques and complications of laparoscopic myomectomy. Materials and methods. A retrospective study was carried out in 74 patients with fibroids >3cm from March, 1995 until May,2000 at PUMC Hospital. Indications for surgery were symptomatic fibroids( 20 cases) , mainly pain or urine frequency ; progressively increasing fibroid size (7 cases); coexistent adnexal pathology( 26 cases) and infertility( 21 cases) . Results. The number of fibroids of each patient varied from 1 to 4 with single fibroid of 62 cases (83.7% ).The fibroids were located in anterior wall (30 cases), posterior wall (23 cases) and fundus (21 cases). A total of 93 fibroids were removed from these patients including 16 intramural fibroids and 77 subserous fibroids. The size of dominant fibroids ranged from 3~ 8 cm (mean 4.8 cm). In 19 cases (25.6% ),the uterine wall was sutured in one layer. Mean duration of operation was 73 minutes and mean blood loss was 82 ml. Longer operating time and more blood loss were observed in patients with fibroids≥ 4cm than those with fibroids <4cm. The difference was statistically significant (P< 0.05). Mean postoperative hospital stay was 3.2 days and overall complication rate was 1.4% . The average postoperative follow-up period was 22 months (1~ 62 months). All the patients with symptoms showed remission of their complaints at 2-month follow-up. Recurrence of fibroid occurred in 1 case 1 year after initial operation and second laparoscopic myomectomy was given to her successfully. Five patients became pregnant. The pregnancy was uneventful and proceeded to selective caesarean section at term pregnancy in 4 cases. One miscarriage occured at 8 weeks in the 5th case. No adhesions at myomectomy site were found in these 5 patients. Conclusions. Our study suggests the feasibility of laparoscopic myomectomy in selected patients, which leads to effectiveness, low complication rate and

    Background Positive end-expiratory pressure (PEEP) can increase intracranial pressure. Pneumoperitoneum and the Trendelenburg position are associated with an increased intracranial pressure. We investigated whether PEEP ventilation could additionally influence the sonographic optic nerve sheath diameter as a surrogate for intracranial pressure during pneumoperitoneum combined with the Trendelenburg position in patients undergoing robot-assisted laparoscopic prostatectomy. Methods After anesthetic induction, 38 patients were randomly allocated to a low tidal volume ventilation (8 ml/kg) without PEEP group (zero end-expiratory pressure [ZEEP] group, n = 19) or low tidal volume ventilation with 8 cmH2O PEEP group (PEEP group, n = 19). The sonographic optic nerve sheath diameter was measured prior to skin incision, 5 min and 30 min after pneumoperitoneum and the Trendelenburg position, and at the end of surgery. The study endpoint was the difference in the sonographic optic nerve sheath diameter 5 min after pneumoperitoneum and the Trendelenburg position between the ZEEP and PEEP groups. Results Optic nerve sheath diameters 5 min after pneumoperitoneum and the Trendelenburg position did not significantly differ between the groups [least square mean (95% confidence interval); 4.8 (4.6–4.9) mm vs 4.8 (4.7–5.0) mm, P = 0.618]. Optic nerve sheath diameters 30 min after pneumoperitoneum and the Trendelenburg position also did not differ between the groups [least square mean (95% confidence interval); 4.5 (4.3–4.6) mm vs 4.5 (4.4–4.6) mm, P = 0.733]. Conclusions An 8 cmH2O PEEP application under low tidal volume ventilation does not induce an increase in the optic nerve sheath diameter during pneumoperitoneum combined with the steep Trendelenburg position, suggesting that there might be no detrimental effects of PEEP on the intracranial pressure during robot-assisted laparoscopic prostatectomy.

    Full Text Available Context Pancreatic surgery is an extremely challenging field, and the management of pancreatic diseases continues to evolve. In the past decade, minimal access surgery is moving towards minimizing the surgical trauma by reducing numbers and size of the port. In the last few years, a novel technique with a single-incision laparoscopic approach has been described for several laparoscopic procedures. Objectives We present a single-port laparoscopic spleen-preserving distal pancreatectomy. To our knowledge, this is the first single-port pancreatic resection in Brazil and Latin America. Methods A 33-year-old woman with neuroendocrine tumor underwent spleen-preserving distal pancreatectomy via single-port approach. A single-incision advanced access platform with gelatin cap, self-retaining sleeve and wound protector was used. Results Operative time was 174 minutes. Blood loss was minimal, and the patient did not receive a transfusion. The recovery was uneventful, and the patient was discharged on postoperative day 4. Conclusions Single-port laparoscopic spleen-preserving distal pancreatectomy is feasible and can be safely performed in specialized centers by skilled laparoscopic surgeons.

    2010-01-01

    Full Text Available This paper documents the first case of gastric cancer associated with Recklinghausen's disease, which was successfully treated by a totally laparoscopic operation. A 67-year-old woman with Recklinghausen's disease was referred to this department to undergo surgical treatment for early gastric cancer. The physical examination showed multiple cutaneous neurofibromas throughout the body surface, which made an upper abdominal incision impossible. Laparoscopic surgery requiring only small incisions was well indicated, and a totally laparoscopic distal gastrectomy with lymph node dissection was performed. Billroth I reconstruction was done intra-abdominally using a delta-shaped anastomosis. The patient followed a satisfactory postoperative course with no complications. Since the totally laparoscopic gastrectomy has many advantages over open surgery, it should therefore be preferentially used as a less invasive treatment in the field of gastric cancer.

    Although mesenterioaxial gastric volvulus is an uncommon entity characterized by rotation at the transverse axis of the stomach, laparoscopic repair procedures have still been controversial. We reported a case of mesenterioaxial intrathoracic gastric volvulus, which was successfully treated with laparoscopic repair of the diaphragmatic hiatal defect using a polytetrafluoroethylene mesh associated with Toupet fundoplication. A 70-year-old Japanese woman was admitted to our hospital because of sudden onset of upper abdominal pain. An upper gastrointestinal series revealed an incarcerated intrathoracic mesenterioaxial volvulus of the distal portion of the stomach and the duodenum. The complete laparoscopic approach was used to repair the volvulus. The laparoscopic procedures involved the repair of the hiatal hernia using polytetrafluoroethylene mesh and Toupet fundoplication. This case highlights the feasibility and effectiveness of the laparoscopic procedure, and laparoscopic repair of the hiatal defect using a polytetrafluoroethylene mesh associated with Toupet fundoplication may be useful for preventing postoperative recurrence of hiatal hernia, volvulus, and gastroesophageal reflux.

    Objective; To introduce our experience in transvaginal NOTES-assisted laparoscopic nephrectomy in a porcine model and access its value. Method:Six female pigs underwent transvaginal NOTES-assisted laparoscopic nephrectomy (3 right, 3 left). A 5 and 10 mm trocar were placed at the right and left margin of umbilicus. The vaginal mucosa in the posterior vaginal fornix was opened by a chiastic 0. 5 cm incision, and a 5 mm trocar was inserted into the abdominal cavity under the direct vision from a 5 mm flexible-tip 0° laparoscope inserted through the 5 mm trocar at the margin of umbilicus. Dissection was performed using operating apparatus placed in the abdominal trocars, under direct vision a-chieved by the 5 mm flexible-tip 0° laparoscope placed through the vaginal trocar. The renal artery, vein, and ureter were blocked by Hem-o-lock and titanium clips. The specimen was placed inside a homemade bag and removed via the incision of posterior vaginal fornix under direct vision with an optic in the abdominal trocar. The vaginal wound was closed using a running 2-0 absorbable suture. Result: A total of 6 transvaginal NOTES-assisted laparoscopic nephrectomies were successfully performed in this series. The median operative time was 100(range 70 to 150)min. The median estimated blood loss was 30(range 20 to 40) ml. On necropsy, no intraabdominal injuries were noted.

    Full Text Available Abstract Background Rectovaginal fistula (RVF is an epithelium-lined communication between the rectum and vagina. Most RVFs are acquired, the most common cause being obstetric trauma. Most of the high RVFs are repaired by conventional open surgery. Laparoscopic repair of RVF is rare and so far only one report is available in the literature. Methods We present a case of high RVF repaired by laparoscopy. 56-year-old female who had a high RVF following laparoscopic assisted vaginal hysterectomy was successfully operated laparoscopically. Here we describe the operative technique and briefly review the literature. Results The postoperative period of the patient was uneventful and after a follow up of 6 months no recurrence was found. Conclusion Laparoscopic repair of high RVF is feasible in selected patients but would require proper identification of tissue planes and good laparoscopic suturing technique.

  1. Distal and non-distal NIP theories

    2011-01-01

    We study one way in which stable phenomena can exist in an NIP theory. We start by defining a notion of 'pure instability' that we call 'distality' in which no such phenomenon occurs. O-minimal theories and the p-adics for example are distal. Next, we try to understand what happens when distality fails. Given a type p over a sufficiently saturated model, we extract, in some sense, the stable part of p and define a notion of stable-independence which is implied by non-forking and has bounded weight. As an application, we show that the expansion of a model by traces of externally definable sets from some adequate indiscernible sequence eliminates quantifiers.

    Carcinoid tumors of the midgut arise from the distal duodenum, jejunum, ileum, appendix, ascending and right transverse colon. The appendix and terminal ileum are the most common location. The majority of carcinoid tumors originate from neuroendocrine cells along the gastrointestinal tract, but they are also found in the lung, ovary, and biliary tracts. We report the first case of elective laparoscopic cholecystectomy in which we found a suspicious lesion at the tip of the appendix and proceeded to perform a laparoscopic appendectomy. The lesion revealed a carcinoid tumor of the appendix. PMID:10323177

    Full Text Available Purpose. To report on the feasibility of a new Laparoscopic Doppler ultrasound (LDU technology to aid in identifying and preserving arterial blood flow within the neurovascular bundle (NVB during robotic prostatectomy (RARP. Materials and Methods. Nine patients with normal preoperative potency and scheduled for a bilateral nerve-sparing procedure were prospectively enrolled. LDU was used to measure arterial flow at 6 anatomic locations alongside the prostate, and signal intensity was evaluated by 4 independent reviewers. Measurements were made before and after NVB dissection. Modifications in nerve-sparing procedure due to LDU use were recorded. Postoperative erectile function was assessed. Fleiss Kappa statistic was used to evaluate inter-rater agreement for each of the 12 measurements. Results. Analysis of Doppler signal intensity showed maintenance of flow in 80% of points assessed, a decrease in 16%, and an increase in 4%. Plane of NVB dissection was altered in 5 patients (56% on the left and in 4 patients (44% on the right. There was good inter-rater reliability for the 4 reviewers. Use of the probe did not significantly increase operative time or result in any complications. Seven (78% patients had recovery of erections at time of the 8-month follow-up visit. Conclusions. LDU is a safe, easy to use, and effective method to identify local vasculature and anatomic landmarks during RARP, and can potentially be used to achieve greater nerve preservation.

    This study aimed to compare clinical outcome and postoperative systemic inflammatory response using C-reactive protein (CRP) levels, to quantify the degree of tissue injury in open mini-laparotomy cystectomy (OMC) versus robot-assisted laparoscopic cystectomy with extracorporeal (RALC-EUD) or intracorporeal urinary diversion (RALC-IUD). From September 2012 to September 2015, 309 patients diagnosed with bladder cancer underwent radical cystectomy with urinary diversion. Of these, 175 patients were eligible for the study and underwent OMC (n = 125), RALC-EUD (n = 12) or RALC-IUD (n = 38). Blood samples were obtained preoperatively and postoperatively on days 1-7. Clinical and perioperative parameters, including demographics, comorbidity, tumour stage and postoperative outcomes, were collected from medical records. Age, American Society of Anesthesiologists score and Charlson score were significantly higher in OMC than in the robotic groups (p = 0.020, 0.012 and 0.008, respectively). Other demographic data showed no significant group differences. Estimated blood loss and blood transfusion volume were higher in OMC (p OMC and RALC-EUD (p OMC CRP levels were higher than RALC-EUD. In this study, robotic techniques seem less traumatic overall than open surgery, as OMC had higher postoperative CRP levels than RALC-EUD. The higher CRP levels in RALC-IUD may be more reflective of the urinary diversion technique than the true tissue trauma.

    AIM: To explore the safety and feasibility of endoscopy-assisted laparoscopic resection of gastrointestinal stromal tumors. METHODS: The clinical data for 95 patients who underwent resection of gastrointestinal stromal tumors by endoscopy-assisted laparoscopic technique, pure laparoscopic technique or traditional open surgery in the Digestive Medical Center of the Second Affiliated Hospital of Nanjing Medical University from 2008 to 2012 were analyzed retrospectively. The operative time, blood loss, time to postoperative recovery of gastrointestinal function, time to ambulation and postoperative length of hospital stay were compared between different groups. RESULTS: All surgeries were completed successfully without death or postoperative complications. None of recurrence or metastasis was found. The operative time was 63.0 min ± 7.8 min, 81.6 min ± 6.0 min and 134.9 min ± 12.9 min in the endoscopy-assisted laparoscopy group, pure laparoscopy group and open surgery group, respectively; the blood loss was 24.5 mL ± 4.6 mL, 27.1 mL ± 7.1 mL and 112.4 mL ± 22.5 mL; the time to recovery of gastrointestinal function was 33.4 h ± 2.7 h, 34.6 h ± 5.2 h and 36.9 h ± 3.2 h; the time to ambulation was 37.1 h ± 4.8 h, 38.0 h ± 3.7 h and 48.6 h ± 4.0 h; and the postoperative length of hospital stay was 7.8 d ± 1.4 d, 8.1 d ± 1.2 d and 9.4 d ± 1.8 d. The operative time was significantly lower in the endoscopy-assisted laparoscopy group than in the pure laparoscopy group (P = 0.000). The operative time, blood loss, time to recovery of gastrointestinal function, time to ambulation and postoperative length of hospital stay were significantly lower in the endoscopy-assisted laparoscopy group than in the open surgery group (all P < 0.05). CONCLUSION: Endoscopy-assisted laparoscopy is a safe and feasible technique for treating gastrointestinal stromal tumors. It has the advantages of minimal invasiveness, accurate positioning, and rapid postoperative recovery. The

    2016-01-01

    Transphyseal distal humerus fractures typically occur in children younger than 3 years secondary to birth trauma, nonaccidental trauma, or a fall from a small height. Prompt and accurate diagnosis of a transphyseal distal humerus fracture is crucial for a successful outcome. Recognizing that the forearm is not aligned with the humerus on plain radiographs may aid in the diagnosis of a transphyseal distal humerus fracture. Surgical management is most commonly performed with the aid of an arthrogram. Closed reduction and percutaneous pinning techniques similar to those used for supracondylar humerus fractures are employed. Cubitus varus caused by a malunion, osteonecrosis of the medial condyle, or growth arrest is the most common complication encountered in the treatment of transphyseal distal humerus fractures. A corrective lateral closing wedge osteotomy can be performed to restore a nearly normal carrying angle.

    Full Text Available Graças ao melhor conhecimento da anatomia segmentar do fígado e desenvolvimento de novas técnicas, houve aumento no número de indicações de hepatectomias. O desenvolvimento da cirurgia minimamente invasiva ocorreu paralelamente e o aumento da experiência, aliado ao desenvolvimento de novos instrumentais, resultaram no crescimento exponencial das ressecções hepáticas videolaparoscópicas. A abordagem laparoscópica pode tornar viável a ressecção hepática em pacientes cirróticos com hipertensão portal que não tolerariam este mesmo procedimento por via laparotômica. A cirurgia robótica surgiu nos últimos anos como a última fronteira de desenvolvimento técnico aplicado à videocirurgia. O presente trabalho descreve a experiência pioneira de ressecção hepática totalmente com o uso de robótica na América Latina, em paciente com carcinoma hepatocelular e cirrose hepática. A hepatectomia laparoscópica com o uso do sistema robótico Da Vinci permite refinamentos técnicos graças à visualização tridimensional do campo cirúrgico e utilização de instrumentais precisos e com grande amplitude de movimentação que simulam os movimentos da mão humana.The surgical robotic system is superior to traditional laparoscopy in regards to 3-dimensional images and better instrumentations.

    Distal humeral epiphyseal separation is an uncommon injury that is often misdiagnosed upon initial presentation. To make a timely, correct diagnosis, the treating physician must have a thorough understanding of basic anatomical relationships and an awareness of the existence of this injury. This is a case of a child who sustained a separation of the distal humeral epiphysis, as well as multiple other bony injuries, secondary to child abuse.

    We report the first case of sigmoid volvulus after laparoscopic surgery for sigmoid colon cancer. The patient is a 75-year-old man who presented with the sudden onset of severe abdominal pain. He had undergone laparoscopic sigmoidectomy for cancer 2 years before presentation. CT scan showed a distended sigmoid colon with a mesenteric twist, or "whirl sign." Colonoscopy showed a mucosal spiral and luminal stenosis with dilated sigmoid colon distally and ischemic mucosa. The diagnosis of ischemic colonic necrosis due to sigmoid volvulus was established. Resection of the necrotic sigmoid colon was performed and a descending colon stoma was created. A long remnant sigmoid colon and chronic constipation may contribute to the development of sigmoid volvulus after laparoscopic sigmoidectomy. Prompt diagnosis is essential for adequate treatment, and colonoscopy aids in the diagnosis of ischemic changes in patients without definitive findings of a gangrenous colon.

    Abstract Rationale: Laparoscopic total pancreatectomy is a complicated surgical procedure and rarely been reported. This study was conducted to investigate the safety and feasibility of laparoscopic total pancreatectomy. Patients and Methods: Three patients underwent laparoscopic total pancreatectomy between May 2014 and August 2015. We reviewed their general demographic data, perioperative details, and short-term outcomes. General morbidity was assessed using Clavien–Dindo classification and delayed gastric emptying (DGE) was evaluated by International Study Group of Pancreatic Surgery (ISGPS) definition. Diagnosis and Outcomes: The indications for laparoscopic total pancreatectomy were intraductal papillary mucinous neoplasm (IPMN) (n = 2) and pancreatic neuroendocrine tumor (PNET) (n = 1). All patients underwent laparoscopic pylorus and spleen-preserving total pancreatectomy, the mean operative time was 490 minutes (range 450–540 minutes), the mean estimated blood loss was 266 mL (range 100–400 minutes); 2 patients suffered from postoperative complication. All the patients recovered uneventfully with conservative treatment and discharged with a mean hospital stay 18 days (range 8–24 days). The short-term (from 108 to 600 days) follow up demonstrated 3 patients had normal and consistent glycated hemoglobin (HbA1c) level with acceptable quality of life. Lessons: Laparoscopic total pancreatectomy is feasible and safe in selected patients and pylorus and spleen preserving technique should be considered. Further prospective randomized studies are needed to obtain a comprehensive understanding the role of laparoscopic technique in total pancreatectomy. PMID:28099344

    Institute of Scientific and Technical Information of China (English)

    2016-01-01

    Laparoscopic liver resection (LLR) has been progressivelydeveloped along the past two decades. Despiteinitial skepticism, improved operative results madelaparoscopic approach incorporated to surgical practiceand operations increased in frequency and complexity.Evidence supporting LLR comes from case-series,comparative studies and meta-analysis. Despite lack oflevel 1 evidence, the body of literature is stronger andexisting data confirms the safety, feasibility and benefitsof laparoscopic approach when compared to openresection. Indications for LLR do not differ from thosefor open surgery. They include benign and malignant(both primary and metastatic) tumors and living donorliver harvesting. Currently, resection of lesions locatedon anterolateral segments and left lateral sectionectomyare performed systematically by laparoscopy in hepatobiliaryspecialized centers. Resection of lesions locatedon posterosuperior segments (1, 4a, 7, 8) and majorliver resections were shown to be feasible but remaintechnically demanding procedures, which should bereserved to experienced surgeons. Hand-assisted andlaparoscopy-assisted procedures appeared to increasethe indications of minimally invasive liver surgery andare useful strategies applied to difficult and majorresections. LLR proved to be safe for malignant lesionsand offers some short-term advantages over openresection. Oncological results including resection marginstatus and long-term survival were not inferior to openresection. At present, surgical community expects highquality studies to base the already perceived betteroutcomes achieved by laparoscopy in major centers'practice. Continuous surgical training, as well as newtechnologies should augment the application of lap-aroscopic liver surgery. Future applicability of newtechnologies such as robot assistance and image-guidedsurgery is still under investigation.

    High-quality images can be readily captured during laparoscopic colon surgery, but there are no guidelines for documentation of these video data or how to best measure surgical quality from an operative video. This study evaluates the feasibility and compliance in documenting key steps during laparoscopic right hemicolectomy and sigmoid colectomy. A retrospective review of previously recorded videos of patients undergoing laparoscopic right hemicolectomy or sigmoid colectomy from September to December 2011 in a single institution was performed. Patients' demographics, intraoperative features, postoperative complications, and variables for video recording and editing were collected. Compliance of key surgical steps was assessed using a checklist by two independent surgeons. Sixteen laparoscopic operations (seven right hemicolectomies and nine sigmoid colectomies) were recorded. Twelve (75%) were laparoscopic-assisted, and four (25%) were hand-assisted laparoscopic operations. Compliance with key surgical steps in laparoscopic right hemicolectomy and sigmoid colectomy was demonstrated in the majority of patients, with steps ranging in compliance from 42.9% to 100% and from 77.8% to 100%, respectively. The edited video had a median duration of 3 minutes 47 seconds (range, 1 minute 44 seconds-5 minutes 38 seconds) with a production time of nearly 1 hour and a resolution of 1440 × 1080 pixels. Key surgical steps during laparoscopic right hemicolectomy and sigmoid colectomy can be documented and edited into a short representative video. Standardization of this process should allow video documentation to improve quality in laparoscopic colon surgery.

    Laparoscopic colorectal resection has been applied to advanced colorectal cancer. Synchronous liver metastasis of colorectal cancer would be treated safely and effectively by simultaneous laparoscopic colorectal and hepatic resection. Seven patients with colorectal cancer and synchronous liver metastasis treated by simultaneous laparoscopic resection were analyzed retrospectively. Three patients received a hybrid operation using a small skin incision, 2 patients underwent hand-assisted laparoscopic surgery using a small incision produced for colonic anastomosis, and 2 patients were treated with pure laparoscopic resection. The mean total operation duration was 407 minutes, and mean blood loss was 207 mL. Negative surgical margins were achieved in all cases. Mean postoperative hospital stay was 16.4 days. No recurrence at the surgical margin was observed in the liver. For selected patients with synchronous liver metastasis of colorectal cancer, simultaneous laparoscopic resection is useful for minimizing operative invasiveness while maintaining safety and curability, with satisfying short- and long-term results.

    Full Text Available Introduction: Laparoscopic surgery is one of the most common procedures performed for benign ovarian masses. The aim of the study was to analyze all benign ovarian masses treated laparoscopically to assess safety, feasibility and outcome. Methods: A prospective study was carried out at Kathmandu Medical College Teaching Hospital, Sinamangal, Nepal. All the patients undergoing laparoscopic surgery for benign ovarian masses from 1st January 2012 to 31st December 2012 were included in the study. The pre-operative findings, intra-operative findings, operative techniques and post-operative complications were analyzed. Results: Thirty-six patients were taken for the study. Two cases were excluded since intra-operatively they were tubo-ovarian masses. The most common tumor was dermoid cyst (n=13; 38.23% and endometriotic cyst (n=14; 41.17%. Out of 34 cases, five cases of endometriotic cyst (14.70% were converted to laparotomy due to severe adhesions and four cases of endometriotic cyst underwent deroofing surgery. Two cases underwent laparoscopic assisted vaginal hysterectomy with bilateral salphingo-oopherectomy. Successful cystectomies were carried out in 22 cases. None were malignant. Major complications were not noted while minor complications like port-site infection (n=3; 8.82% and subcutaneous emphysema (n=1; 2.9% were present. Conclusions: Laproscopic management of benign ovarian masses is safe and feasible.

    The technology that has permitted the rapid advance of minimal access surgery has now made it feasible to perform laparoscopically assisted colon resections safely. As the instrumentation improves, specimen removal problems are solved, surgeons' sewing skills improve, and other anastomotic methods are devised, an increasing amount of colonic surgery will be done using laparoscopy. It is clear that the techniques now in use are evolving, and will be substantially different a few years hence. Previously accepted surgical principles may continue to be challenged by new techniques, which must be evaluated under strict protocol before being widely accepted. These operations should be performed by surgeons who are able to achieve the same level of radical operation that they would achieve through a laparotomy. Special training in advanced laparoscopic techniques including microsurgical suturing is a distinct advantage in performing these operations successfully. It may be best for surgeons to start with palliative procedures or operations for benign diseases of the colon, to avoid the risk of jeopardizing an operation for cancer.

    Laparoscopic liver resection (LLR) has been progressively developed along the past two decades. Despite initial skepticism, improved operative results made laparoscopic approach incorporated to surgical practice and operations increased in frequency and complexity. Evidence supporting LLR comes from case-series, comparative studies and meta-analysis. Despite lack of level 1 evidence, the body of literature is stronger and existing data confirms the safety, feasibility and benefits of laparoscopic approach when compared to open resection. Indications for LLR do not differ from those for open surgery. They include benign and malignant (both primary and metastatic) tumors and living donor liver harvesting. Currently, resection of lesions located on anterolateral segments and left lateral sectionectomy are performed systematically by laparoscopy in hepatobiliary specialized centers. Resection of lesions located on posterosuperior segments (1, 4a, 7, 8) and major liver resections were shown to be feasible but remain technically demanding procedures, which should be reserved to experienced surgeons. Hand-assisted and laparoscopy-assisted procedures appeared to increase the indications of minimally invasive liver surgery and are useful strategies applied to difficult and major resections. LLR proved to be safe for malignant lesions and offers some short-term advantages over open resection. Oncological results including resection margin status and long-term survival were not inferior to open resection. At present, surgical community expects high quality studies to base the already perceived better outcomes achieved by laparoscopy in major centers' practice. Continuous surgical training, as well as new technologies should augment the application of laparoscopic liver surgery. Future applicability of new technologies such as robot assistance and image-guided surgery is still under investigation.

    The objective of our study was to compare clinical and pathologic outcomes of robot-assisted and open abdominal techniques for treatment of uterine cancer in obese patients. Institutional review board approval was obtained. Patient demographic data, pathological data, and surgical data were collected by retrospective chart review. Data were analyzed using SAS statistical software. One-hundred and eighty-nine consecutive cases of suspected uterine cancer were identified from October 2003 until January 2009. Of these, 116 patients (61%) had a body mass index (BMI) over 30. There were 66 completed robot-assisted hysterectomies (RAHs), 43 total abdominal hysterectomies (TAHs), and seven patients that were converted from RAH to open abdominal hysterectomy. There were no significant differences in preoperative patient demographics, including body mass index (BMI), medical co-morbidities, or preoperative cytology, except for parity. There were no differences in postoperative grade, stage, lymph vascular space invasion, positive pelvic washings, mean number of pelvic lymph nodes, or proportion of patients undergoing pelvic lymphadenectomy. Length of stay and estimated blood loss were lower for the robotic technique; RAHs had a significantly longer operative time, however. Postoperative blood transfusions and wound infections were more frequent in the TAH group. Of the RAH group there were seven conversions to TAH (10%). Differences in surgical times with and without lymphadenectomy were least in patients in the largest BMI category of >50. Length of time required for RAH was significantly longer then TAH in obese and morbidly obese patients, however benefits to patients of a minimally invasive approach included reduced incidence of wound infections, reduced transfusion rates, reduced blood loss, and shortened length of stay. These data also suggest the greatest advantage of robotic technology over laparotomy in patients with BMI over 50.

In Brazil, this approach has not yet been previously reported. Objective: Our goal is to describe Step-by-Step the Retzus-sparing RARP surgical technique and report our first Brazilian experience. Methods: We present a case of a 60-year-old white man with low risk prostate cancer. Surgical materials were four arms Da Vinci robotic platform system, six transperitoneal portals, two prolene wires and Polymer Clips. This surgical technique was step-by-step described according to Galfano et al. One additional step was added as a modification of Galfano et al. Primary technique description: The closure of the Denovellier fascia. Results: We have operated one patient with this technique. The operative time was 180minutes, console time was135 min, the blood loss was 150ml, none perioperative or postoperative complications was found, hospital stay of 01 day. The anatomopathological classification revealed a pT2aN0M0 specimen with free surgical margins. The patient achieved continence immediately after bladder stent retrieval. Full erection reported after 30 days of surgery. Conclusion: Retzus-sparing RARP approach is feasible and reproducible. However, further comparative studies are necessary to demonstrate potential benefits in continence and sexual outcomes over the standard approaches.
