Objective This study was performed to introduce a new method of minimally invasive subtalar arthrodesis (MISA) and assess its clinical effects on traumatic subtalar arthritis (TSA). Methods Fifteen patients (8 male and 7 female; age range, 36–56 years; mean age, 48.67 years) with TSA who underwent MISA were included. All patients were treated using a series instrument. The intraoperative and postoperative indexes were recorded. Results Among all patients, the mean operation time was 59.67 ± 16.31 minutes and the mean intraoperative blood loss was 43.33 ± 52.87 mL. Four patients underwent iliac crest bone graft surgery, and one patient developed a complication involving fat liquefaction of the iliac crest wound. The mean bony fusion time among all patients was 3.5 months. According to the American Orthopaedic Foot and Ankle Society standard, an excellent outcome was obtained in eight patients and a good outcome was obtained in seven patients. The operation time and intraoperative blood loss were significantly different between patients who did and did not undergo iliac crest bone graft surgery. Conclusion MISA is a simple and effective method for the treatment of TSA.

Background: The Ommaya reservoir implantation technique allows for bypass of the blood-brain barrier. It can be continuously administered locally and be used to repeatedly flush the intracranial cavity to achieve the purpose of treatment. Accurate, fast, and minimally invasive placement of the drainage tube is essential during the Ommaya reservoir implantation technique, which can be achieved with the assistance of robots.Methods: We retrospectively analyzed a total of 100 patients undergoing Ommaya reservoir implantation, of which 50 were implanted using a robot, and the remaining 50 were implanted using conventional surgical methods. We then compared the data related to surgery between the two groups and calculated the accuracy of the drainage tube of the robot-assisted group.Results: The average operation time of robot-assisted surgery groups was 41.17 ± 11.09 min, the bone hole diameter was 4.1 ± 0.5 mm, the intraoperative blood loss was 11.1 ± 3.08 ml, and the average hospitalization time was 3.9 ± 1.2 days. All of the Ommaya reservoirs were successful in one pass, and there were no complications such as infection or incorrect placement of the tube. In the conventional Ommaya reservoir implantation group, the average operation time was 65 ± 14.32 min, the bone hole diameter was 11.3 ± 0.3 mm, the intraoperative blood loss was 19.9 ± 3.98 ml, and the average hospitalization time was 4.1 ± 0.5 days. In the robot-assisted surgery group, the radial error was 2.14 ± 0.99 mm and the axial error was 1.69 ± 1.24 mm.Conclusions: Robot-assisted stereotactic Ommaya reservoir implantation is quick, effective, and minimally invasive. The technique effectively negates the inefficiencies of craniotomy and provides a novel treatment for intracranial lesions.

Abstract We aim to evaluate the surgical outcome of laparoendoscopic two-site myomectomy (LETS-M). The medical records of 204 women receiving LETS-M in a tertiary referral center, including 183 surgeries performed by the experienced surgeon and 21 surgeries performed by 3 well-supervised trainees were retrospectively reviewed. The age of the participants was 39.3±6.4 years. The mean diameter of the largest myoma was 8.5±2.2 cm. The mean weight of the myomas was 281.1±183.1 g. The operation time was 97.6±40.2 min, and the intraoperative blood loss was 99.3±115.2 mL. There were 3 (1%) cases of excessive blood loss (more than 500 mL) and 2 (1%) of postoperative hematoma. The only significant difference between the experienced surgeon and trainees was the operation time (92.3±32.2 min vs. 141.2±54 min, p<.001), while the myoma number, myoma diameter, myoma weight, and intraoperative blood loss were not significantly different. The operation time did not differ among different myoma locations. In multivariate analysis, virginity, myoma number, more than 2 large myomas, and myoma size were independent variables for longer operation times. No patient experienced any major complications. The result revealed that LETS-M is a minimally invasive surgical method that is safe, effective, and easy to learn for managing uterine myoma.

Background. Clinically, autologous iliac crest bone grafts (ICBG) and bone tamping methods are often applied to manage depressed tibial plateau fractures (DTPFs). The purpose of this study was to describe and evaluate the technique of using structural bicortical autologous ICBG combined with the tunnel bone tamping method (TBTM) for treating DTPFs. Methods. All patients with DTPFs who underwent structural bicortical autologous ICBG combined with TBTM from January 2016 to February 2018 were prospectively analysed. Demographics, injury, surgery, postoperative complications, and clinical outcomes were recorded. All patients were followed up for more than 30 months. Postoperative radiography and CT were employed to assess fracture healing and the reduction quality. Results. Forty-three of the included patients completed the follow-up. No malreduction was observed. Based on the immediate postoperative imaging, the intra-articular step-off was significantly reduced (8.19 mm preoperatively vs. 1.30 mm immediate postoperatively, P < 0.001 ). From the immediate operation to the latest follow-up, the reduction was maintained significantly well, with a nonnegligible absolute difference (0.18 mm, P = 0.108 ). A remarkable secondary loss of reduction (intra-articular step   off > 3   mm ) was found in two elderly patients (2/43, 4.65%). The incidence of complications related to the bone-graft donor and bone-graft site was 2.33% and 4.65%, respectively. At the final follow-up, the mean Hospital for Special Surgery (HSS) score of the knee was 98.19 ± 2.89 , and the mean 36-Item Short-Form Health Survey (SF-36) score was 95.65 ± 4.59 . Conclusion. Structural bicortical autologous ICBG combined with TBTM is radiologically effective and stable in terms of complications for the DTPFs.

Background. Superficial duodenal neoplasms (SDNs) are a challenging target in the digestive tract. Surgical resection is invasive, and it is difficult to determine the site and extent of the lesion from outside the intestine and resect it locally. Endoscopic submucosal dissection (ESD) has scarcely been utilized in the treatment of duodenal tumors because of technical difficulties and possible delayed perforation due to the action of digestive juices. Thus, no standard treatments for SDNs have been established. To challenge this issue, we elaborated endoscopy-assisted laparoscopic full-thickness resection (EALFTR) and analyzed its feasibility and safety.Methods. Twenty-four SDNs in 22 consecutive patients treated by EALFTR between January 2011 and July 2012 were analyzed retrospectively.Results. All lesions were removed en bloc. The lateral and vertical margins of the specimens were negative for tumor cells in all cases. The mean sizes of the resected specimens and lesions were 28.9 mm (SD ± 10.5) and 13.3 mm (SD ± 11.6), respectively. The mean operation time and intraoperative estimated blood loss were 133 min (SD ± 45.2) and 16 ml (SD ± 21.1), respectively. Anastomotic leakage occurred in three patients (13.6%) postoperatively, but all were minor leakage and recovered conservatively. Anastomotic stenosis or bleeding did not occur.Conclusions. EALFTR can be a safe and minimally invasive treatment option for SDNs. However, the number of cases in this study was small, and further accumulations of cases and investigation are necessary.

Object: To investigate effects of the high ligation of hernia sac with absorbable string for children with indirect inguinal hernia. Method: A retrospective analysis of 92 patients with inguinal hernia who underwent the high ligation of hernia sac was conducted in the present study, in which 20 cases underwent the high ligation of hernia sac with absorbable string while 72 cases treated with the high ligation of hernia sac with non-absorbable suture. The mean operation time, mean intraoperative blood loss and average postoperative hospital stay and postoperative pain rating were analyzed. Results: Though no statistical difference existed in the mean operation time, mean intraoperative blood loss, average postoperative hospital stay between the two groups (P>0.05). However, the postoperative pain in the high ligation of hernia sac with absorbable string group was significantly lower than that of the non-absorbable group. Conclusion: Compared with that of the high ligation of hernia sac with non-absorbable string, there is lower grade postoperative pain in the high ligation with absorbable suture.

Fifteen consecutive patients with hindfoot pain after calcaneal fracture underwent subtalar arthrodesis using interposition iliac crest bone graft. Outcome and correction of calcaneal collapse were assessed before and after surgery with clinical examination, visual analogue scores, and standard x-rays while weightbearing. Eleven of the 15 patients were satisfied with the procedure. There were four failures due to transverse tarsal joint arthritis, overcorrection, and reflex sympathetic dystrophy. Radiographic examination revealed restoration of heel height, with 100% union rate of the arthrodesis. The described technique allows arthrodesis and correction of calcaneal collapse after calcaneal fracture.

Abstract Background: Tourniquets are commonly used during foot and ankle surgery to provide a bloodless operative field and for the sake of the surgeon`s comfort, despite the potential risks associated with it. This study was performed to compare postoperative outcomes of tourniquet-assisted to non-tourniquet-assisted operative fixation of calcaneal fractures.Methods: A total of 131 patients with closed calcaneal fracture who underwent minimally invasive surgery of calcaneal fractures between March 2015 and December 2018 were reviewed retrospectively. Patients for whom a tourniquet was used intraoperatively (n = 62) were compared to those without (n = 69). Operating time and visualization, blood loss, postoperative pain according to visual analogue scale (VAS), the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot score, and hospital length of stay were recorded for all the patients.Results: Statistical analysis of the results showed significant differences between tourniquet and non-tourniquet groups in the mean operation time, visibility of the surgical field, mean estimated intraoperative and postoperative blood loss, and mean VAS pain scores 24 H, 48 H, 72 H postoperatively (P < 0.05), whereas no significant difference between two groups in the mean Serum CPK levels, post-operative swelling, mean length of stay, AOFAS score, wound and fracture healing time, and the mean time for return to work.Conclusion: Our study demonstrated that tourniquet application during minimally invasive surgery of calcaneal fractures can significantly shorten the operation time, improve surgical visualization, and reduce intraoperative blood loss. However, adverse events associated with the use of tourniquet include increased postoperative pain, and more amount of postoperative bleeding. Due to higher postoperative pain and more amount of postoperative bleeding, more attention should be paid on the postoperative phase for those who tourniquet was used. The surgeon's decision to use a tourniquet during calcaneal fractures surgery should be carefully considered.
