Objective
To investigate the feasibility and necessity of endoscopic thyroidectomy with central lymph node dissection via the combined breast and trans-oral approaches.Methods
Six patients with papillary thyroid carcinoma who underwent endoscopic total thyroidectomy with central node dissection via combined breast and trans-oral approaches from November 2014 to January 2015 in Zhongshan Hospital, Xiamen University, were analyzed.Results
After completion of endoscopic central lymph node dissection via the traditional breast approach, eight pieces of lymph nodes could still be dissected via the trans-oral approach. Two of these eight pieces were positive for thyroid cancer metastasis.Conclusions
It is advisable to perform endoscopic central lymph node dissection for thyroid carcinoma via the breast approach combined with the trans-oral approach.2.
Purpose
Hypocalcemia after total thyroidectomy is a concern for every endocrine surgeon. We conducted this study to establish the value of the macroscopic appearance of preserved parathyroid glands after thyroidectomy in predicting post-thyroidectomy hypocalcemia.Methods
In 2009, 237 patients underwent total thyroidectomy at our hospital. The macroscopic appearance of the preserved parathyroid glands was recorded and the serum calcium and intact parathyroid hormone levels were measured postoperatively.Results
Thirteen patients (5.5 %) had transient hypocalcemia and 1 patient (0.4 %) had permanent hypocalcemia. All of the hypocalcemia patients with more than one normal preserved parathyroid had asymptomatic transient hypocalcemia that did not require medication. The sensitivity, specificity, positive predictive value, and negative predictive value for hypocalcemia with at least 1 normal preserved parathyroid were 78.6, 79.4, 19.3, and 98.3 %, respectively.Conclusion
The macroscopic appearance of preserved parathyroid glands and the number of well-preserved parathyroid glands after thyroidectomy proved effective in predicting post-thyroidectomy hypocalcemia.3.

Purpose
Several video-assisted and robotic surgery techniques have been reported for resection of the thyroid and parathyroid glands. Our institute has started performing endoscopic thyroidectomy using the Lap-protector and E·Z-access system, referred to as E·Z-access using video-assisted neck surgery (EZ-VANS). In this report, we evaluate the safety and efficacy of this technique.Methods
From January 2007 to September 2014, 110 patients underwent resection of a primary thyroid tumor, 73 who underwent a cervical collar incision (the Open group) and 37 underwent EZ-VANS (the EZ-VANS group).Results
The average operating time was 159 and 172 min in the Open group and EZ-VANS group, respectively; the amount of blood loss was 46.5 and 54.7 ml, respectively; and the length of hospital stay after surgery was 4.3 and 5.2 days, respectively, with no significant differences observed between the two groups. The learning curve for the EZ-VANS technique was shorter than for open surgery.Conclusions
We confirmed that the EZ-VANS technique is a safe and useful method for resection of benign and early malignant thyroid tumors.4.

Background
A higher incidence of gastrojejunal (GJ) anastomotic strictures has been reported following laparoscopic gastric bypass (LRYGB) with the 21 mm compared to 25 mm circular stapler. We hypothesized that the rate of stricture formation is affected by route of anvil insertion and its position relative to the gastric pouch staple line [trans‐gastric above staple line (trans‐gastric) vs. trans‐oral through staple line (trans‐oral)] following LRYGB.Methods
Retrospective review of consecutive patients who underwent LRYGB with circular stapled GJ studied in four groups: trans-gastric‐21 mm, trans-gastric‐25 mm, trans-oral‐21 mm, and trans-oral-25 mm. Primary outcome studied was GJ stricture; secondary outcomes were results with endoscopic therapy and weight loss at 12 months. Predictors studied were age, gender, body mass index (BMI), comorbidities, and operative technical factors including anvil size and insertion route. Regression analyses were performed to identify predictors of GJ stricture.Results
Eight hundred seventy-six patients underwent LRYGB. Seventy-six (8.7 %) developed a GJ stricture. The highest stricture rate occurred in the trans-gastric‐21 mm group (17 %, p?<?.01 for all comparisons). Stricture rates were similar for trans-gastric‐25 mm (8.4 %), trans-oral‐21 mm (5.2 %), and trans-oral‐25 mm (1.6 %) groups. Independent predictors of stricture were: trans-gastric‐21 mm (OR 10.9, 95%CI 1.4–85.1; p?=?.022) and age (OR 0.97, 95%CI 0.95–0.99; p?=?.002). Endoscopic dilation relieved symptoms in all patients. There was no difference in %EWL at 12 months in patients with and without a stricture.Conclusions
We conclude that the trans-oral-21 mm anvil is associated with a low stricture rate. With the advantage of smaller abdominal wall wound, trans-oral‐21 mm may be the preferred size and route of anvil insertion.5.

Introduction and hypothesis
The objective was to evaluate vaginal and clitoral sensation before and after robotic sacrocolpopexy for the repair of pelvic organ prolapse.Methods
Twenty-two women, mean age 63 years (range 41–77), were admitted for robotic sacrocolpopexy repair of pelvic organ prolapse; 4 were lost to follow-up. Quantitative sensory thresholds for warm, cold, and vibratory sensations were measured at the vagina (anterior and posterior areas) and clitoris 1 day before and a mean of 12?±?4 months following surgery. Student’s paired t test was used to compare sensory thresholds before and after surgery.Results
For the 18 women who completed follow-up, sensitivity was significantly higher after surgery (sensory threshold decreased) at the clitoral and vaginal regions, to cold and warm stimuli. In contrast, the vaginal and clitoral vibratory sensory thresholds did not change significantly following surgery.Conclusion
The repair of pelvic organ prolapse by robotic sacrocolpopexy could potentially play a role in restoring clitoral and vaginal wall sensation. The effects of these sensory changes on sexual function and the quality of sexual life need further investigation.6.
Objective
To evaluate iliopsoas atrophy and loss of function after displaced lesser trochanter fracture of the hip.Design
Cohort study.Setting
District hospital.Patients
Twenty consecutive patients with pertrochanteric fracture and displacement of the lesser trochanter of?>?20 mm.Intervention
Fracture fixation with either an intramedullary nail or a plate.Outcome measurements
Clinical scores (Harris hip, WOMAC), hip flexion strength measurements, and magnetic resonance imaging findings.Results
Compared with the contralateral non-operated side, the affected side showed no difference in hip flexion force in the supine upright neutral position and at 30° of flexion (205.4 N vs 221.7 N and 178.9 N vs. 192.1 N at 0° and 30° flexion, respectively). However, the affected side showed a significantly greater degree of fatty infiltration compared with the contralateral side (global fatty degeneration index 1.085 vs 0.784), predominantly within the psoas and iliacus muscles.Conclusion
Severe displacement of the lesser trochanter (>?20 mm) in pertrochanteric fractures did not reduce hip flexion strength compared with the contralateral side. Displacement of the lesser trochanter in such cases can lead to fatty infiltration of the iliopsoas muscle unit. The amount of displacement of the lesser trochanter did not affect the degree of fatty infiltration.Level of evidence

Background
Intraoperative identification of the difficult-to-spot parathyroid gland is critical during surgery for thyroid and parathyroid disease. Recently, intrinsic fluorescence of the parathyroid gland was identified, and a new method was developed for intraoperative detection of the parathyroid with an original fluorescent detection apparatus. Here, we describe a method for intraoperative detection of the parathyroid using a ready-made photodynamic eye (PDE) system without any fluorescent dye or contrast agents.Methods
Seventeen patients who underwent surgical treatment for thyroid or parathyroid disease at Kagoshima University Hospital were enrolled in this study. Intrinsic fluorescence of various tissues was detected with the PDE system. Intraoperative in vivo and ex vivo intrinsic fluorescence of the parathyroid, thyroid, lymph nodes and fat tissues was measured and analyzed.Results
The parathyroid gland had a significantly higher fluorescence intensity than the other tissues, including the thyroid glands, lymph nodes and fat tissues, and we could identify them during surgery using the fluorescence-guided method. Our method could be applicable for two intraoperative clinical procedures: ex vivo tissue identification of parathyroid tissue and in vivo identification of the location of the parathyroid gland, including ectopic glands.Conclusion
The PDE system may be an easy and highly feasible method to identify the parathyroid gland during surgery.8.

Background
Robotic surgery is increasingly being used for complex oncologic operations, although currently there is no standardized curriculum in place for surgical oncologists. We describe the evolution of a proficiency-based robotic training program implemented for surgical oncology fellows, and demonstrate the outcomes of the program.Methods
A 5-step robotic curriculum began integration in July 2013. Fellows from July 2013 to August 2017 were included. An education portfolio was created for each fellow, including pre-fellowship experience, fellowship experience with data from robotic curriculum and operative experience, and post-fellowship practice information.Results
Of 30 fellows, 20% completed a prior fellowship, 97% trained at an academic residency, 57% had prior robotic training (median 5 h), and 43% had performed robotic surgery (median 0 cases). In fellowship, on average, fellows spent 5 h on the virtual reality curriculum and performed 19 biotissue anastomoses. For total surgeries, fellows operating from the console increased over time (p = 0.005). For pancreas, the average percentage of robotic pancreaticoduodenectomy (PD) steps completed increased (p < 0.011), as did the number of PDs in which the fellow completed the entire resection (p = 0.013). Fellows were 10 times more likely to complete the entire distal than PD from the console (p < 0.01). Post-fellowship, 83% of fellows obtained an academic position, 88% utilized robotics, and 91% performed pancreatic surgery.Conclusions
With dedicated training, fellows can safely primarily perform complex gastrointestinal robotic surgeries and, after graduation, take jobs incorporating this skill set. In this era of scrutiny on cost and outcomes, specialized training programs offer a safe integration option for complex technical skills.9.
Purpose
To review our experience with robotic guided S2-alar iliac (S2AI) screw placement.Methods
We retrospectively reviewed patients who underwent S2AI fixation with robotic guidance. Screw placement and deviation from the preoperative plan were assessed by fusing preoperative CT (with the planned S2AI screws) to postoperative CT. The software’s measurement tool was used to compare the planned vs. actual screw placements in axial and lateral views, at entry point to the S2 pedicle and at a 30 mm depth at the screws’ mid-shaft, in a resolution of 0.1 mm. Medical charts were reviewed for technical issues and intra-operative complications.Results
35 S2AI screws were reviewed in 18 patients. The patients’ mean age was 60 years. No intra-operative complications that related to the placement of S2AI screws were reported and robotic guidance was successful in all 35 screws. Post-operative CT scans showed that all trajectories were accurate. No violations of the iliac cortex or breaches of the anterior sacrum were noted. At the entry point, the screw deviated from the pre-operative plan by 3.0 ± 2.2 mm in the axial plane and 1.8 ± 1.6 mm in the lateral plane. At 30 mm depth, the screw deviated from the pre-operative plan by 2.1 ± 1.3 mm in the axial plane and 1.2 ± 1.1 mm in the lateral plane.Conclusions
Robotic guided S2AI screw placement is feasible and accurate. No screw malpositions or complications that related to the placement of S2AI screws occurred in this series. Larger studies are needed to assess the long-term clinical outcomes of robotic guided sacral-pelvic fixation.10.

Background
Severe obesity is often characterized by ectopic fat deposition, which is related to development of type 2 diabetes (T2D). Thus, resolution of T2D may not be linearly associated with weight loss. The importance of ectopic fat reduction after bariatric surgery and T2D resolution is uncertain.Objective
The aim of this pilot study is to compare body composition and body fat distribution in severely obese patients with or without T2D after biliopancreatic diversion with duodenal switch (BPD-DS) surgery in relation to diabetes resolution.Methods
Sixty-two severely obese patients were evaluated at baseline, 6, and 12 months. Of these, 40 patients underwent BPD-DS surgery. Anthropometric measurements and abdominal and mid-thigh computed tomography scans were performed at each visit.Results
Before BPD-DS surgery, obese patients with T2D had higher weight as well as greater ectopic fat deposition in the abdomen and mid-thigh level than obese patients without T2D (p?<?0.05). Resolution of T2D was 65 and 90 % at 6 and 12 months, respectively. No difference in body composition changes at 6 and 12 months could be found between patients without T2D, patients with T2D resolution, and patients who remained T2D. Resolution of T2D was associated with a greater absolute loss of visceral adipose tissue (VAT) in comparison to patients without T2D (?1175?±?570 cm3 vs. ?729?±?394 cm3 at 6 months and ?1647?±?816 cm3 vs. ?1103?±?422 cm3 at 12 months; all p?≤?0.05).Conclusion
Ectopic fat mobilization, particularly the absolute loss of VAT, may play a major role in T2D resolution following BPD-DS surgery, regardless of the amount of weight loss.11.

Background
In recent years, increasingly sophisticated tools have allowed for more complex robotic surgery. Robotic hepatectomy, however, is still in its infancy. Our goals were to examine the adoption of robotic hepatectomy and to compare outcomes between open and robotic liver resections.Methods
The robotic hepatectomy experience of 64 patients was compared to a modern case-matched series of 64 open hepatectomy patients at the same center. Matching was according to benign/malignant diagnosis and number of segments resected. Patient data were obtained retrospectively. The main outcomes and measures were operative time, estimated blood loss, conversion rate (robotic to open), Pringle maneuver use, single non-anatomic wedge resection rate, resection margin size, complication rates (infectious, hepatic, pulmonary, cardiac), hospital stay length, ICU stay length, readmission rate, and 90-day mortality rate.Results
Sixty-four robotic hepatectomies were performed in 2010–2014. Forty-one percent were segmental and 34 % were wedge resections. There was a 6 % conversion rate, a 3 % 90-day mortality rate, and an 11 % morbidity rate. Compared to 64 matched patients who underwent open hepatectomy (2004–2012), there was a shorter median OR time (p = 0.02), lower median estimated blood loss (p < 0.001), and shorter median hospital stay (p < 0.001). Eleven of the robotic cases were isolated resections of tumors in segments 2, 7, and 8.Conclusions
Robotic hepatectomy is safe and effective. Increasing experience in more centers will allow definition of which hepatectomies can be performed robotically, and will enable optimization of outcomes and prospective examination of the economic cost of each approach.13.
Objective
To clarify the contribution of the subcutaneous area during breast approach endoscopic thyroidectomy (BAET), with regard to invasiveness-related outcomes.Methods
Seventy-two patients were randomly assigned to two groups: standard dissection and limited dissection. Postoperative pain and inflammatory response were compared between groups.Results
The groups were well matched except for subcutaneous dissection area (137.11 ± 21.10 vs. 83.69 ± 12.10 cm2, p < 0.0001). No significant difference was found with regard to VAS score and postoperative inflammatory response.Conclusion
Our RCT indicated that the subcutaneous area plays a less important role with regard to BAET-related postoperative pain.14.

Background
A few studies have reported only short-term outcomes of various robotic and laparoscopic liver resection types; however, published data in left lateral sectionectomy (LLS) have been limited. The aim of this study was to compare the long- and short-term outcomes of robotic and laparoscopic LLS.Methods
We retrospectively compared demographic and perioperative data as well as postoperative outcomes of robotic (n = 12) and laparoscopic (n = 31) LLS performed between May 2007 and July 2013. Resection indications included malignant tumors (n = 31) and benign lesions (n = 12) including intrahepatic duct (IHD) stones (n = 9).Results
There were no significant differences in perioperative outcomes of estimated blood loss, major complications, or lengths of stay, but operating time was longer in robotic than in laparoscopic LLS (391 vs. 196 min, respectively) and the operation time for IHD stones did not differ between groups (435 vs. 405 min, respectively; p = 0.190). Disease-free (p = 0.463) and overall (p = 0.484) survival of patients with malignancy did not differ between groups. The 2- and 5-year disease-free survival rates were 63.2 and 36.5 %, respectively. However, robotic LLS costs were significantly higher than laparoscopic LLS costs ($8183 vs. $5190, respectively; p = 0.009).Conclusions
Robotic LLS was comparable to laparoscopic LLS in surgical outcomes and oncologic integrity during the learning curve. Although robotic LLS was more expensive and time intensive, it might be a good option for difficult indications such as IHD stones.15.
Background
The aim of this study was to compare the outcomes of single-site robotic cholecystectomy with multi-port laparoscopic cholecystectomy within a high-volume tertiary health care center.Methods
A retrospective analysis of prospectively maintained data was conducted on patients undergoing single-site robotic cholecystectomy or multi-port laparoscopic cholecystectomy between October 2011 and July 2014. A single surgeon performed all the surgeries included in the study.Results
A total of 678 cholecystectomies were performed. Of these, 415 (61%) were single-site robotic cholecystectomies and 263 (39%) were multi-port laparoscopic cholecystectomies. Laparoscopic patients had a greater mean BMI (30.5 vs. 29.0 kg/m2; p = 0.008), were more likely to have undergone prior abdominal surgery (83.3 vs. 41.4%; p < 0.001) and had a higher incidence of preexisting comorbidities (76.1 vs. 67.2%; p = 0.014) as compared to the robotic group. There was no statistical difference in the total operative time, rate of conversion to open procedure and mean length of follow-up between the two groups. The mean length of hospital stay was shorter for patients within the robotic group (1.9 vs. 2.4 days; p = 0.012). Single-site robotic cholecystectomy was associated with a higher rate of wound infection (3.9 vs. 1.1%; p = 0.037) and incisional hernia (6.5 vs. 1.9%; p = 0.006).Conclusion
Multi-port laparoscopic cholecystectomy should remain the gold standard therapy for gallbladder disease. Single-site robotic cholecystectomy is an effective alternative procedure for uncomplicated benign gallbladder disease in properly selected patients. This must be carefully balanced against a high rate of surgical site infection and incisional hernia, and patients should be informed of these risks.16.
Objective
Anatomic reconstruction of the posterior facet by primary stabilization of the calcaneal fracture with a locking nail.Indications
All intraarticular calcaneal fractures and unstable two-part fractures independent of the degree of closed/open soft tissue trauma.Contraindications
High perioperative risk, soft tissue infection, beak fracture (type II fracture) and still open apophysis.Surgical technique
Anatomic reduction of the posterior facet using a sinus tarsi approach. Reduction and temporary fixation of the sustentacular, tuberosity, and anterior process fragments with 1.8–2.0 mm Kirschner wires. Thereafter, the C-Nail (calcaneus nail) is introduced with its guiding device stabilizing the sustentacular, tuberostity, and anterior process fragments through its three guiding arms with 6 or 7 locking screws.Postoperative management
Passive and active motion starts on postoperative day 2. Lymph drains help reduce swelling. Partial weightbearing with 20 kg for 6–8 weeks in the patient’s own shoes is recommended. X?ray controls are done at 4 and 8 weeks as well as after 6 and 12 months.Results
A total of 107 calcaneal fractures treated with the C-Nail between 2011 and 2014 were evaluated according to the AOFAS score 6 months and 1 year after surgery. The measured values were on average 93.0 (range 65–100) points at 6 months and 94.1 (range 75–100) points 12 months after the surgery. Böhler’s angle with initial traumatic values of 6.2° (?30 to +13°) improved postoperatively to 31.8°, after 3 months slightly decreased to 29.6°, and after 12 months to 28.3°. There were 2 cases of superficial wound necrosis (1.9?%) and 1 case a deep infection (0.93?%) with need of early C-Nail removal.17.
Background
Thoracic cord herniation is a well-established entity in the literature. Majority of the published literature deals with its surgical management in terms of “mere” detethering of cord. However, not much is written about the degree of herniation and ectopic cord tissue and its management.Case summary
A 58-year-old male presented to us with progressive difficulty in walking. Imaging revealed a cord herniation at T7–8 level. Surgical detethering was planned. However, a significant amount of “ectopic” cord tissue was found outside the dural defect intra-operatively. Simple detethering and repositioning was difficult. Hence, the ectopic tissue was excised under neuro-physiologic monitoring and no major change was recorded intra-operatively/post-operatively.Conclusions
Thoracic cord herniation surgery may be more than simple detethering and cord repositioning. If encountered in similar situations intra-operatively, surgeons should be able to excise ectopic tissue without grave post-operative deficits. Neuronal plasticity probably plays an important role in the pathophysiology of long-standing cord herniation.18.

Background
Operating room (OR) turnover time, time taken between one patient leaving the OR and the next entering, is an important determinant of OR utilization, a key value metric for hospital administrators. Surgical robots have increased the complexity and number of tasks required during an OR turnover, resulting in highly variable OR turnover times. We sought to streamline the turnover process and decrease robotic OR turnover times and increase efficiency.Methods
Direct observation of 45 pre-intervention robotic OR turnovers was performed. Following a previously successful model for handoffs, we employed concepts from motor racing pit stops, including briefings, leadership, role definition, task allocation and task sequencing. Turnover task cards for staff were developed, and card assignments were distributed for each turnover. Forty-one cases were observed post-intervention.Results
Average total OR turnover time was 99.2 min (95% CI 88.0–110.3) pre-intervention and 53.2 min (95% CI 48.0–58.5) at 3 months post-intervention. Average room ready time from when the patient exited the OR until the surgical technician was ready to receive the next patient was 42.2 min (95% CI 36.7–47.7) before the intervention, which reduced to 27.2 min at 3 months (95% CI 24.7–29.7) post-intervention (p < 0.0001).Conclusions
Role definition, task allocation and sequencing, combined with a visual cue for ease-of-use, create efficient, and sustainable approaches to decreasing robotic OR turnover times. Broader system changes are needed to capitalize on that result. Pit stop and other high-risk industry models may inform approaches to the management of tasks and teams.19.

Objectives
To analyze the robotic approach as treatment of iatrogenic ureteral injuries.Methods
Medical records were reviewed for patients undergoing robotic-assisted laparoscopic ureteral reimplantation at the University of Missouri from 2009 to 2014. Patient charts were analyzed for demographics, prior abdominal surgeries, circumstances of injury, outcomes, and other relevant information.Results
Nine patients met inclusion criteria. The average age was 44.6. Patients had an average of 4.3 abdominal surgeries. Injury occurred during hysterectomy (open, laparoscopic, or vaginal) in eight patients (88.9 %), five cases were laparoscopic, two utilized robotic assistance, and one injury occurred during uterosacral vault suspension. All cases were related to gynecological procedures. On average, ureteral injury was detected 17.2 days after the initial surgery and repaired 62.3 days after initial operation. The average surgical repair time was 295.9 min (range 168–498) with an average blood loss of 77.2 mL (range 20–150). Four patients required a psoas hitch, with one receiving both a psoas hitch and a Boari flap. Postoperatively, patients had an average hospital stay of 2.7 days. One patient had ileus for greater than 3 days, and another was readmitted within 30 days for pain control and antiemetics following stent removal. One patient underwent open reimplantation 3 years after original surgery for development of ureteral stricture. At follow-up, all patients had returned to baseline renal function.Conclusions
Robotic approach is feasible and a safe option for distal iatrogenic ureteral injuries occurring during gynecological procedures. Prior abdominal surgery or delayed repair does not preclude a robotic approach.20.
