Background: Robotic approach for rectal cancer competes with laparoscopy in centers dedicated to minimally invasive surgery (MIS) due to the technologic advantage. This is a report of our experience with MIS for rectal cancer. Methods: A series of 84 consecutive patients with laparoscopic resection (between 1995-2010) and 38 consecutive patients with robotic resection (between 2008-2010) for primary rectal cancer were analyzed. Hartmann's procedures were excluded. Clinical and pathologic outcomes were reviewed retrospectively. Results: In the laparoscopic group (LG), 50 anterior rectal resections (ARR), 34 abdominal perineal resections (APR) were performed while in the robotic group(RG) there were 30 ARR and 8 APR. The median operative time was 182 min (140-220 min) in LG and 208 min (180- 300 min) in RG (p=0.0002). No statistically significant difference was noticed between the groups in terms of conversion, morbidity, anastomotic leak and postoperative stay rates. Margin clearance was obtained in all patients and the median number of removed lymph nodes was similar: 11.37 in RG vs 11.07 in the LG (p=0.65) with a higher rate of metastatic lymph node involvement in laparoscopy (p=0.0012). Blood loss was higher in LG (150 ml vs. 100 ml; p=0.0001). There were 5 (5.9%) local recurrences in the LG at a median follow- up of 27.5 months and 2 (5.2%) in the RG at a median follow-up of 13 months (p=0.43). Conclusions: Minimally invasive surgery for rectal cancer proved to be safe and efficient with similar results in the two groups. Technological advances of robotic approach compared to laparoscopy allowed better ergonomics, more refined dissection, easier preserving of hypogastric nerves and less blood loss. Long term outcomes are to be assessed in prospective randomized studies.

Invasive Approach

Overview: Minimally invasive surgery (MIS) of colorectal cancer has become more popular in the past two decades. Laparoscopic colectomy has been accepted as an alternative standard approach in colon cancer, with comparable oncologic outcomes and several better short-term outcomes compared to open surgery. Unlike the treatment for colon cancer, however, the minimally invasive approach in rectal cancer has not been established. In this article, we summarize the current status of MIS for rectal cancer and explore the various technical options.

Introduction: Endometrial carcinoma is one of the commonest gynaecological cancer in developed countries as well as developing countries. The mainstay of initial treatment of endometrial carcinoma is surgical staging which may be performed by either the conventional abdominal approach or by minimally invasive route i.e. laparoscopic or robotic. Objectives: The purpose of this study was to compare and evaluate the surgical staging, safety and clinical benefits of minimally invasive surgeries versus. laparotomy in patients with endometrial cancer. Methodology: We retrospectively analyzed 105 patients with endometrial cancer over a period of five years and compared the outcome of total hysterectomy with pelvic and para-aortic lymphadenectomy by abdominal, laparoscopic approach or robotic-assisted surgery. Comparison was done with respect to operative time, blood loss, number of lymph nodes retrieved, length of hospital stay, intraoperative and postoperative complications. The data were analyzed using paired “t”- test / Wilcoxon signed rank test ,χ2 - test, Pearson correlation coefficient “r” whenever found suitable. P value of less than 0.05 was considered as statistically significant. Result: There was no statistically significant difference seen in the baseline characteristics like age and BMI between the two groups. The laparotomies were done in a shorter time than the minimally invasive approach (p<0.001). The amount of blood loss (p=0.002), and the duration of hospital stay (p<0.001) was significantly less in the minimally invasive surgery group than the laparotomies. Not much difference in the lymph node retrieval was observed between the two arms (p=0.614). The number of complications were almost similar in both the groups. Conclusion: Minimally invasive surgery for surgical staging of endometrial carcinoma is feasible and effective than laparotomy. The amount of blood loss and duration of hospital stay is seen much lesser with MIS than laparotomy.

OBJECT Back pain is an increasing concern for the aging population. This study aims to evaluate if minimally invasive surgery presents cost-minimization benefits compared with open surgery in treating adult degenerative scoliosis. METHODS Seventy-one patients with adult degenerative scoliosis received 2-stage, multilevel surgical correction through either a minimally invasive spine surgery (MIS) approach with posterior instrumentation (n = 38) or an open midline (Open) approach (n = 33). Costs were derived from hospital and rehabilitation charges. Length of stay, blood loss, and radiographic outcomes were obtained from electronic medical records. Functional outcomes were measured with Oswestry Disability Index (ODI) and visual analog scale (VAS) surveys. RESULTS Patients in both cohorts were similar in age (AgeMIS = 65.68 yrs, AgeOpen = 63.58 yrs, p = 0.28). The mean follow-up was 18.16 months and 21.82 months for the MIS and Open cohorts, respectively (p = 0.34). MIS and Open cohorts had an average of 4.37 and 7.61 levels of fusion, respectively (p < 0.01). Total inpatient charges were lower for the MIS cohort ($269,807 vs $391,889, p < 0.01), and outpatient rehabilitation charges were similar ($41,072 vs $49,272, p = 0.48). MIS patients experienced reduced length of hospital stay (7.03 days vs 14.88 days, p < 0.01) and estimated blood loss (EBL) (EBLMIS = 470.26 ml, EBLOpen= 2872.73 ml, p < 0.01). Baseline ODI scores were lower in the MIS cohort (40.03 vs 48.04, p = 0.03), and the cohorts experienced similar 1-year improvement (ΔODIMIS = −15.98, ΔODIOpen = −21.96, p = 0.25). Baseline VAS scores were similar (VASMIS = 6.56, VASOpen= 7.10, p = 0.32), but MIS patients experienced less reduction after 1 year (ΔVASMIS = −3.36, ΔVASOpen = −4.73, p = 0.04). Preoperative sagittal vertical axis (SVA) were comparable (preoperative SVAMIS = 63.47 mm, preoperative SVAOpen = 71.3 mm, p = 0.60), but MIS patients had larger postoperative SVA (postoperative SVAMIS = 51.17 mm, postoperative SVAOpen = 28.17 mm, p = 0.03). CONCLUSIONS Minimally invasive surgery demonstrated reduced costs, blood loss, and hospital stays, whereas open surgery exhibited greater improvement in VAS scores, deformity correction, and sagittal balance. Additional studies with more patients and longer follow-up will determine if MIS provides cost-minimization opportunities for treatment of adult degenerative scoliosis.

OBJECT Minimally invasive surgery (MIS) techniques are becoming a more common means of treating adult spinal deformity (ASD). The aim of this study was to compare the hybrid (HYB) surgical approach, involving minimally invasive lateral interbody fusion with open posterior instrumented fusion, to the circumferential MIS (cMIS) approach to treat ASD. METHODS The authors performed a retrospective, multicenter study utilizing data collected in 105 patients with ASD who were treated via MIS techniques. Criteria for inclusion were age older than 45 years, coronal Cobb angle greater than 20°, and a minimum of 1 year of follow-up. Patients were stratified into 2 groups: HYB (n = 62) and cMIS (n = 43). RESULTS The mean age was 60.7 years in the HYB group and 61.0 years in the cMIS group (p = 0.910). A mean of 3.6 interbody fusions were performed in the HYB group compared with a mean of 4.0 interbody fusions in the cMIS group (p = 0.086). Posterior fusion involved a mean of 6.9 levels in the HYB group and a mean of 5.1 levels in the cMIS group (p = 0.003). The mean follow-up was 31.3 months for the HYB group and 38.3 months for the cMIS group. The mean Oswestry Disability Index (ODI) score improved by 30.6 and 25.7, and the mean visual analog scale (VAS) scores for back/leg pain improved by 2.4/2.5 and 3.8/4.2 for the HYB and cMIS groups, respectively. There was no significant difference between groups with regard to ODI or VAS scores. For the HYB group, the lumbar coronal Cobb angle decreased by 13.5°, lumbar lordosis (LL) increased by 8.2°, sagittal vertical axis (SVA) decreased by 2.2 mm, and LL–pelvic incidence (LL-PI) mismatch decreased by 8.6°. For the cMIS group, the lumbar coronal Cobb angle decreased by 10.3°, LL improved by 3.0°, SVA increased by 2.1 mm, and LL-PI decreased by 2.2°. There were no significant differences in these radiographic parameters between groups. The complication rate, however, was higher in the HYB group (55%) than in the cMIS group (33%) (p = 0.024). CONCLUSIONS Both HYB and cMIS approaches resulted in clinical improvement, as evidenced by decreased ODI and VAS pain scores. While there was no significant difference in degree of radiographic correction between groups, the HYB group had greater absolute improvement in degree of lumbar coronal Cobb angle correction, increased LL, decreased SVA, and decreased LL-PI. The complication rate, however, was higher with the HYB approach than with the cMIS approach.

Abstract Background The purpose of this study was to investigate the clinical effect of minimally invasive surgery for inguinal cryptorchidism. Methods The patients were divided into the minimally invasive surgery group (n = 100) and the traditional surgery group (n = 58). In the minimally invasive surgery group, patients with low inguinal cryptorchidism (n = 54) underwent surgery with a transscrotal incision, and patients with high inguinal cryptorchidism (n = 46) underwent laparoscopic surgery. Results There was no difference in the hospital stay duration or cost between the minimally invasive surgery group and the traditional surgery group (P > 0.05). As for the operative time, minimally invasive surgery of low inguinal cryptorchidism was shorter than traditional surgery (P = 0.033), while minimally invasive surgery of high inguinal cryptorchidism was comparable to traditional surgery (P = 0.658). Additionally, there were no cases of testicular atrophy, testicular retraction, inguinal hernia or hydrocele in either group. There was no significant difference in the incidence of poor wound healing between the two groups (P > 0.05). Although there was no significant difference in the incidence of scrotal hematoma between the two groups (P > 0.05), the incidence in the minimally invasive surgery group was higher than that in the traditional surgery group. Conclusions Minimally invasive surgery including a transscrotal incision for low inguinal cryptorchidism and laparoscopic surgery for high inguinal cryptorchidism is as safe and effective as traditional surgery, and could also provide a good cosmetic effect for children.

Object The main aim of this study was to compare clinical and radiological outcomes after stabilization by a percutaneous transpedicular system and stabilization from the standard open approach for thoracolumbar spine injury. Methods Thirty-seven consecutive patients were enrolled in the study over a period of 16 months. Patients were included in the study if they experienced 1 thoracolumbar fracture (A3.1–A3.3, according to the AO/Magerl classification), had an absence of neurological deficits, had no other significant injuries, and were willing to participate. Eighteen patients were treated by short-segment, minimally invasive, percutaneous pedicle screw instrumentation. The control group was composed of 19 patients who were stabilized using a short-segment transpedicular construct, which was performed through a standard midline incision. The pain profile was assessed by a visual analog scale (VAS), and overall satisfaction by a simple 4-stage scale relating to performance of daily activities. Working ability and return to original occupation were also monitored. Radiographic follow-up was defined by the vertebral body index (VBI), vertebral body angle (VBA), and bisegmental Cobb angle. The accuracy of screw placement was examined using CT. Results The mean surgical duration in the percutaneous screw group was 53 ± 10 minutes, compared with 60 ± 9 minutes in the control group (p = 0.032). The percutaneous screw group had a significantly lower perioperative blood loss of 56 ± 17 ml, compared with 331 ± 149 ml in the control group (p < 0.001). Scores on the VAS in patients in the percutaneous screw group during the first 7 postoperative days were significantly lower than those in the control group (p < 0.001). There was no significant difference between groups in VBI, VBA, and Cobb angle values during follow-up. There was no significant difference in screw placement accuracy between the groups and no patients required surgical revision. There was no significant difference between groups in overall satisfaction at the 2-year follow-up (p = 0.402). Working ability was insignificantly better in the percutaneous screw group; previous working position was achieved in 17 patients in this group and in 12 cases in the control group (p = 0.088). Conclusions This study confirms that the percutaneous transpedicular screw technique represents a viable option in the treatment of preselected thoracolumbar fractures. A significant reduction in blood loss, postoperative pain, and surgical time were the main advantages associated with this minimally invasive technique. Clinical, functional, and radiological results were at least the same as those achieved using the open technique after a 2-year follow-up. The short-term benefits of the percutaneous transpedicular screw technique are apparent, and long-term results have to be studied in other well-designed studies evaluating the theoretical benefit of the percutaneous technique and assessing whether the results of the latter are as durable as the ones achieved by open surgery.

The application of minimally invasive surgery (MIS) to resect pediatric solid tumors offers the potential for reduced postoperative morbidity with smaller wounds, less pain, fewer surgical site infections, decreased blood loss, shorter hospital stays, and less disruption to treatment regimens. However, significant controversy surrounds the question of whether a high-fidelity oncologic resection of childhood cancers can be achieved through MIS. This review outlines the diverse applications of MIS to treat pediatric malignancies, up to and including definitive resection. This work further summarizes the current evidence supporting the efficacy of MIS to accomplish a definitive, oncologic resection as well as appropriate patient selection criteria for the minimally invasive approach.

Abstract Background Simulation-based practice has become increasingly important in minimally invasive surgery (MIS) training. Nevertheless, personnel resources for demonstration and mentoring simulation-based practice are limited. Video tutorials could be a useful tool to overcome this dilemma. However, the effect of video tutorials on MIS training and improvement of MIS skills is unclear. Methods A prospective randomised trial (n = 24 MIS novices) was conducted. A video-trainer with three different tasks (#1 – 3) was used for standardised goal-directed MIS training. The subjects were randomised to two groups with standard instructional videos (group A, n = 12) versus comprehensive video tutorials for each training task watched at specific times of repetition (group B, n = 12). Performance was analysed using the MISTELS score. At the beginning and following the curriculum, an MIS cholecystectomy (CHE) was performed on a porcine organ model and analysed using the GOALS score. After 18 weeks, participants performed 10 repetitions of tasks #1 – 3 for follow-up analysis. Results More participants completed tasks #1 and #2 in group B (83.3 and 75%) than in group A (66.7 and 50%, ns). For task #2, there was a significant improvement in precision in group B (p < 0.001). For the entire cohort, the GOALS-Scores were 12.9 before and 18.9 after the curriculum (p < 0.001), with no significant difference between groups. Upon follow-up, 84.2% (task#1), 26.3% (task#2) and 100% (task#3) of MIS novices were able to reach the defined goals (A vs. B ns). There was a trend for a better MISTELS score in group B upon follow-up. Conclusions Standardised comprehensive video tutorials watched frequently throughout practice can significantly improve precision in MIC training. This aspect should be incorporated in MIS training.
