ObjectiveTo summarize the clinical progress of minimally invasive techniques in treatment of pilonidal disease.MethodThe relevant literatures about minimally invasive techniques in the treatment of pilonidal disease in recent years were reviewed.ResultsAbout hair removal and carbolic acid injection, they had less damage, fewer complications, higher recurrence rate compared to other surgery, and did not affect the second treatment. The fibrin injection could not clarify its role in the treatment of pilonidal disease due to some defects in the clinical design. Bascom Ⅰhad the advantages of fast recovery and no need for hospitalization, with a recurrence rate of 8%–16%. According to the results of some current clinical researches, it was a promising operation. Sinus resection required further clinical evaluation due to the limited results of current researches. A clinical study of more than 1 000 cases over 10 years showed that the recurrence rate in 10 years was 16%. Compared with frequently used pilonidal operations, the trephine technique was associated with a lower recurrence rate and a lower incidence of postoperative complication. Some short-term clinical researches showed that endoscopic pilonidal sinus treatment was a safe, minimally invasive, and less complication treatment.ConclusionsCompared with frequently used pilonidal operations, minimally invasive technique has the advantages of shortening the hospital stay, shortening the healing time, and reducing complications. It is worth of application.
ObjectiveTo explore the method and experience in correction of pectus carinatum with minimally invasive procedure. MethodsBetween June 2010 and January 2014, 30 patients with pectus carinatum were corrected by minimally invasive procedure. There were 21 boys and 9 girls whose average age was 13 years and 2 months (range, from 8 years and 10 months to 18 years and 9 months), including 24 cases of first operation, 2 recurrence after traditional pectus carinatum correction, and 4 cases secondary to median thoracotomy. Thirty patients had symmetric and asymmetric mild pectus carinatum. ResultsThe operation was performed successfully in all patients, and no severe complication occurred. The operation time was 42-95 minutes (mean, 70 minutes). The bleeding volume during operation was 4-30 mL (mean, 10 mL). The time from operation to discharge was 6-10 days (mean, 7 days). The average time of follow-up was 25 months (range, 9-54 months). All surgical wound healed primarily with no infection. The X-ray films showed slight pneumothorax in 7 cases, and it was absorbed after 1 month without treatment. Loosening of internal fixation was found in 1 patient because of trauma at 6 months, and operation was performed again. The bar was removed at 2 years in 21 patients. The patients had good thoracic contour and normal activity. ConclusionMinimally invasive procedure for correction of pectus carinatum is safe and will get satisfactory effect in maintaining thoracic contour. It has also less trauma and shorter operation time.
Objective To explore safety and efficacy of total laparoscopic radical resection of hilar cholangiocarcinoma. Methods From April 2016 and January 2017, 6 patients with hilar cholangiocarcinoma underwent laparoscopic radical resection in the Affiliated Hospital of Xuzhou Medical University were collected. The intra- and post-operative situation and the postoperative complications were analyzed. Results The radical resections of hilar cholangiocarcinoma were completed laparoscopically in all the patients. There was no conversion to the laparotomy. The procedure was finished within a time of (231.3±94.5) min and with an intraoperative blood loss of (123.3±46.8) mL. The first postoperative exhausting time and the postoperative hospital stay was (2.7±0.3) d and (11.9±1.7) d, respectively. All the patients had the R0 resection and the numbers of dissected lymph nodes were 9.4±2.7. The postoperative complications occurred in 2 patients, they were all cured spontaneously in one week, and there was no perioperative death. None of patients had a local recurrence and metastasis during an average 8 months of following-up. Conclusions Preliminary results of limited cases in this study show that with suitable case and skillful laparoscopic technique, laparoscopic radical resection of hilar cholangiocarcinoma is feasible and safe. Further studies are still needed to confirm benefits of this approach.
ObjectiveTo explore the effectiveness of thoracoscopic surgery for treating late-presenting congenital diaphragmatic hernias and summarize the experience. MethodsBetween October 2012 and February 2015, 21 children with late-presenting congenital diaphragmatic hernias underwent thoracoscopic surgery. Of the 21 cases, 12 were girls and 9 were boys with a median age of 1 year and 3 months (range, 2 months to 8 years). Eight patients had obvious symptom in the initial stage:shortness of breath and dyspnea; 13 cases were found occasionally through chest radiography. Of 21 cases, 17 had left diaphragmatic hernias and 4 had right diaphragmatic hernias. The emergency surgery was performed in 5 cases because oppressed obviously and selective operation in 16 cases. Hernial sac existed in 5 cases; there were 19 cases of Bochdalek's hernia and 2 cases of Morgagni's hernia. The size of diaphragmatic defect ranged from 3 cm×2 cm to 5 cm×5 cm. ResultsThe operation time was 35-80 minutes (mean, 50 minutes), and intraoperative blood loss was 3-5 mL (mean, 3.8 mL). Primary healing of incision was obtained. Postoperative abdominal distension and pneumothorax occurred in 12 and 2 cases respectively. The follow-up time was 1-3 years (mean, 20 months). All the cases had a good recovery and satisfactory appearance of the thoracic incision. The symptoms and signs of shortness of breath and dyspnea disappeared. There was no recurrence and chest infection. ConclusionUnder the conditions of mastering operative indications strictly, thoracoscopic repair for late-presenting congenital diaphragmatic hernia is safe and feasible. It can facilitate the procedure and decrease the recurrence rate relying on intraoperative application of hernia repair needle, knot pusher-assistant, and reasonable processing defect periphery.
Objective To compare the effectiveness between minimally invasive cannulated screw and open reduction and plate fixation in treatment of humeral greater tuberosity fracture by a prospective case-control study. Methods Between January 2008 and January 2011, 49 cases of humeral greater tuberosity fractures were treated with minimally invasive cannulated screw in 25 cases (trial group), and with open reduction and plate fixation in 24 cases (control group). There was no significant difference in gender, age, injury cause, disease duration, fracture displacement, injury side, and complications between 2 groups (P gt; 0.05). The length of incision, operation time, intraoperative blood loss, and hospitalization days were recorded. According to Neer grading system, the effectiveness was evaluated; fracture healing was observed by X-ray films. Results The trial group had smaller incision, shorter operation time, less blood loss, and shorter hospitalization days than the control group, showing significant differences (P lt; 0.01). Superficial infection occurred in 2 cases of the control group, and were cured after symptomatic treatment; primary healing of incision was obtained in the others of 2 groups. All patients were followed up 1-4 years (mean, 2.3 years). The fracture healing time was (7.0 ± 2.3) weeks in the trial group, and was (7.8 ± 2.1) weeks in the control group, showing no significant difference (t=1.24, P=0.22). No heterotopic ossification or loosening and breakage of internal fixation occurred during follow-up. The shoulder function Neer score of the trial group (86.3 ± 2.8) was significantly higher than that of the control group (80.1 ± 2.1) (t=6.37, P=0.00). The results were excellent in 14 cases, good in 8 cases, fair in 2 cases, and poor in 1 case with an excellent and good rate of 88.0% in the trial group; the results were excellent in 12 cases, good in 7 cases, fair in 2 cases, and poor in 3 cases with an excellent and good rate of 79.2% in the control group; and difference had no statistical significance (Z=0.83, P=0.41). Conclusion Compared with open reduction and plate fixation, minimally invasive cannulated screw for greater tuberosity fracture has the advantages of simple operation, less trauma, less intraoperative blood loss, and good shoulder function recovery.
ObjectiveTo investigate the effectiveness of individual percutaneous cannulated screws fixation of computer-assisted design combined with three-dimensional (3D) guide plate by comparing with cast immobilization and open internal fixation for treatment of Herbert type Ib scaphoid fracture. MethodsBetween January 2010 and June 2015, 56 patients with fresh Herbert type Ib scaphoid fracture were treated with cast immobilization in 16 cases (external fixation group), with open reduction and internal fixation in 20 cases (open reduction group), and with individual percutaneous cannulated screws fixation of computer-assisted design combined 3D guide plate in 20 cases (minimal invasion group). There was no significant difference in gender, age, injury cause, side, disease duration, and classification of fractures between groups P>0.05).The time of bone union, bone nonunion rate, return-to-work time, wrist range of motion (ROM), and Mayo function score were recorded and compared. ResultsPrimary healing of incision was obtained in open reduction group and minimally invasion group, without related complications. The cases were followed up 10-24 months (mean, 16.6 months). The time of bone union and return-to-work time of minimal invasion group were significantly shorter than those of the other 2 groups (P<0.05), and the rate of bone nonunion was significantly lower than that of the other 2 groups (P<0.05). At last follow-up, the wrist ROM of minimal invasion group[(104.40±3.46)°] was significantly larger than that of external group[(94.20±2.42)°] and open reduction group[(96.40±2.66)°] (P<0.05). According to Mayo function score, the results were excellent in 6 cases, good in 5 cases, fair in 2 cases, and poor in 3 cases in external fixation group, with an excellent and good rate of 69%; the results were excellent in 9 cases, good in 7 cases, fair in 2 cases, and poor in 2 cases in open reduction group, with an excellent and good rate of 80%; the results were excellent in 16 cases, good in 3 cases, and fair in1 case in minimal invasion group, with an excellent and good rate of 95%; there was significant difference in excellent and good rate among groups (P<0.05). ConclusionIndividual percutaneous cannulated screws fixation of computer-assisted design combined with 3D guide plate has satisfactory effectiveness in the treatment of Herbert type Ib scaphoid fractures, with the advantages of mini-invasion, high accuracy, high rate of bone union, less complication, early return-to-work time.

ObjectiveTo evaluate the effectiveness of percutaneous retrograde pubic screw implantation assisted by hollow pedicle opener in pubic branch fractures.MethodsThe clinical data of 42 patients with pubic branch fractures treated by hollow screw fixation between March 2008 and March 2019 were analyzed retrospectively. According to the operation method, they were divided into the traditional operation group (20 cases in group A, fixed with traditional retrograde pubic screws) and the modified operation group (22 cases in group B, fixed with percutaneous retrograde pubic screws assisted by hollow pedicle opener). There was no significant difference (P>0.05) between the two groups in terms of gender, age, cause of injury, fracture classification, comorbidity, and time from injury to operation. The operation time, blood loss, incision length, screw length, and complications were recorded and compared between the two groups. The fracture reduction was evaluated according to Matta standard on the next day after operation, and the function was evaluated by Majeed score at 12 months after operation.ResultsThe operation was successfully completed in both groups. The operation time, blood loss, and incision length of group B were significantly less than those of group A (P<0.05); there was no significant difference in screw length between the two groups (t=0.793, P=0.437). All patients were followed up 8-24 months, with an average of 16.8 months. There was no complication in the two groups, such as injury of blood vessels and nerves, fracture of internal fixation, screw entering into joint cavity, and nonunion of fracture. There was no significant difference in the fracture healing time between the two groups (t=−1.068, P=0.299). There were 2 cases of incision infection, 1 case of incision fat liquefaction, 2 cases of lower extremity deep vein thrombosis in group A, the incidence of complications was 25.0%; there was only 1 case of lower extremity deep vein thrombosis in group B, the incidence of complication was 4.5%, which was lower than that in group A, but the difference was not significant (χ2=2.104, P=0.147). In group A, 1 case was found to be dislocated, but in group B, there was no dislocated fracture. There was no significant difference between the two groups in the evaluation of Matta imaging on the next day after operation and the evaluation of Majeed function at 12 months after operation (P>0.05).ConclusionPercutaneous retrograde pubic screw implantation assisted by hollow pedicle opener is effect for the pubic branch fractures with the advantage of smaller incision, shorter operation time, and less bleeding compared with traditional methods.
