Objective To explore effectiveness of minimally invasive internal fixation with locking plates for mid-shaft clavicle fractures. Methods Between October 2022 and August 2023, 28 patients with mid-shaft clavicle fractures were treated by minimally invasive internal fixation with locking plates. There were 10 males and 18 females with a mean age of 46.2 years (range, 18-74 years). The fractures were caused by traffic accident in 16 patients, sports-related injury in 7 patients, and other injuries in 5 patients. According to Robinson classification, the fractures were classified as type 2A1 in 1 case, type 2A2 in 6 cases, type 2B1 in 15 cases, and type 2B2 in 6 cases. The interval between fracture and operation ranged from 5 hours to 21 days (median, 1.0 days). The pain visual analogue scale (VAS) score was 8.1±1.6. The VAS score at 3 days after operation and the occurrence of complications after operation were recorded. During follow-up, X-ray films were re-examined to observe the healing of the fracture; the shoulder joint function was evaluated according to the Constant-Murley score at 6 months, and the length of the incision scar (total length of the distal and proximal incisions) was measured. ResultsAll operations were successfully completed without any subclavian vascular or nerve damage. All incisions healed by first intention. The VAS score was 1.2±0.7 at 3 days after operation, and there was a significant difference in VAS score between pre- and post-operation (t=8.704, P<0.001). At 1 week after operation, the patient’s shoulder was basically painless, and they resumed normal life. All patients were followed up 12-20 months (mean, 13.3 months). X-ray films showed that the bone callus began to form at 2-4 months after operation (mean, 2.7 months). There was no delayed healing or non healing of the fracture, and no loosening or fracture of the internal fixators during follow-up. At 6 months after operation, the mean total incision length was 1.5 cm (range, 1.1-1.8 cm); no patient complained of numbness or paresthesia on subclavicular region or anterior chest wall. The Constant-Murley score of shoulder joint function was 93-100 (mean, 97.6). Conclusion Minimally invasive internal fixation with locking plates is a good surgical method for treating mid-shaft clavicle fractures, with simple operation, minimal trauma, good postoperative results, and high satisfaction.
Objective To systematically evaluate the effectiveness and safety of minimally invasive video-assisted thyroidectomy (MIVAT) and conventional open thyroidectomy (COT) in treatment of thyroid carcinoma without lymph node metastasis. Methods Databases including PubMed, EMbase, The Cochrane Library (Issue 3, 2015), WanFang, CBM, VIP and CNKI were searched to collect the randomized controlled trails (RCTs) and non-RCTs about MIVAT and COT in treatment of thyroid carcinoma without lymph node metastasis. The retrieval time was from inception to October 2015. The studies were screened according to the inclusion and exclusion criterias, and the data was extracted and the quality of studies was evaluated by 2 reviewers independently. Then the Meta-analysis was conducted by using RevMan 5.2 software. Results A total of 13 non-RCTs involving 3 083 cases were included. The results of Meta-analysis showed that: compared with COT group, operative time of MIVAT group was longer (MD=31.36, 95% CI: 27.68-35.03, P<0.05), hospital stay (MD=-0.16, 95% CI: -0.28--0.04, P=0.01) and length of scar (MD=-1.51, 95% CI: -1.63--1.39, P<0.05) of MIVAT group were shorter, but there was no significant difference in the incidences of transient hypocalcemia (OR=1.29, 95% CI: 0.93-1.78, P=0.13), transient laryngeal nerve palsy (OR=1.42, 95% CI: 0.93-2.17, P=0.11), hemotoma (OR=1.21, 95% CI: 0.64-2.29, P=0.56), recurrence (OR=0.61, 95% CI: 0.28-1.33, P=0.22), number of retrieved central lymph nodes (MD=-0.10, 95% CI: -0.98-0.78, P=0.82), and the size of tumors (MD=-0.02, 95% CI: -0.06-0.02, P=0.39) between the 2 groups. Conclusion MIVAT is safe and feasible in treatment of thyroid carcinoma without lymph node metastasis when its indications are strictly controlled.
ObjectiveTo evaluate clinical curative effect of sphincter preservation method of improved minimally invasive surgery to primary cure for horseshoe-shaped perianal abscess. MethodsOne hundred and twenty hospitalized patients diagnosed as horseshoe-shaped perianal abscess were analyzed by prospective, random, single-blind, parallel-group design method, and were randomly divided into two groups, one group of sphincter preservation method of improved minimally invasive surgery (observation group), another group of traditional method of hanging line drainage and multiple incisions of radian shape (control group). The cure rate, long-term recurrence, postoperative pain score within 9 d, hospitalization time, incision healing time, scar area after healing, postoperative anal function score and perioperative and long-term complications were compared in these two groups. ResultsAll the operations were successfully completed in these two groups. There were 56 cases of primary healing in the observation group and 55 cases of primary healing in the control group. Compared with the control group, the postoperative pain score on day 2-4 or on day 7-9 was lower (P < 0.05), the incision healing time was shorter (P < 0.05), and the postoperative anal function score was lower (P < 0.05) in the observation group. There was no incision infection and hemorrhoea in these two groups. The hospitalization time, scar area after healing, incidence rate of urinary retention, hepatic and renal dysfunction, and the total white blood cells > 10.0×109/L had no significant differences between these two groups (P > 0.05). There was no long-term recurrence, anal stenosis, and anal incontinence during following-up of 6 months in these two groups. ConclusionPreliminary research results show that sphincter preservation method of improved minimally invasive surgery to primary cure for horseshoe-shaped perianal abscess has a reliable clinical curative effect, fast healing, and less postoperative complications.
ObjectiveTo summarize experience of laparoscopy combined with choledochoscopy common bile duct exploration for patients with schistosomiasis liver cirrhosis with common bile duct stones. MethodThe clinical data of 45 patients with schistosomiasis liver cirrhosis combined with common bile duct stones (liver function Child-Pugh grade A and B) admitted in this hospital from September 2012 to September 2015 were analyzed retrospectively. ResultsTwenty cases were successfully treated by laparoscopy combined with choledochoscopy (laparoscope group), 25 cases were treated by conventional open common bile duct exploration (laparotomy group). Two cases were converted to laparotomy due to bleeding during laparoscopic operation. The mean operation time, intraoperative bleeding, postopera-tive hospitalization time, and postoperative total complications rate had no significant differences between these two groups (P>0.05). There were 2 cases of pulmonary infection and 1 case of incision infection in the laparoscope group, and 1 case of grade A bile leakage and 1 case of pulmonary infection in the laparotomy group, there was no common bile duct stone residual in these two groups. ConclusionAlthough laparoscopic surgery is more difficult for schistosomiasis liver cirrhosis combined with common bile duct stones patients, it is safe and feasible. Appropriate perioperative management and precise laparoscopic and choledochoscopic operation are key to success of operation.
Objective To explore the effectiveness of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) for degenerative lumbar scoliosis stenosis by expandable tubular retractor. Methods Between April 2009 and October 2010, 39 patients with degenerative lumbar scoliosis stenosis were treated. Of 39 patients, 20 underwent MI-TLIF (group A) and 19 underwent open surgery (group B). There was no significant differences in gender, age, disease duration, range of lumbar degenerative scoliosis, Cobb angle, Oswestry disability index (ODI), and visual analogue scale (VAS) between 2 groups (P gt; 0.05). The operation time, intraoperative blood loss, postoperative independently turning over time, postoperative complication rate, Cobb angle, fusion rates, ODI score, and VAS score were compared between 2 groups. Results The operation time of group A was significantly longer than that of group B (P lt; 0.05), and the intraoperative blood loss of group A was significantly less than that of group B (P lt; 0.05); no significant difference was found in postoperative independently turning over time between 2 groups (t=1.869, P=0.069). The complication rate was 20.0% (4/20) in group A and 26.3% (5/19) in group B, showing no significant difference (χ2=0.219, P=0.640). All patients were followed up 2 years to 3 years and 6 months (mean, 2.9 years). At last follow-up, the fusion rate of bone graft was 92.9% (78/84) in group A and 95.2% (80/84) in group B, showing no significant difference (χ2=0.425, P=0.514). According to the Macnab standard for effectiveness evaluation, the results were excellent in 12 cases, good in 6 cases, fair in 1 case, and poor in 1 case, with an excellent and good rate of 90.0% in group A; the results were excellent in 12 cases, good in 5 cases, and fair in 2 cases, with an excellent and good rate of 89.5% in group B; there was no significant difference between 2 groups (Z= — 0.258, P=0.835). The postoperative VAS score, ODI score, and Cobb angle were significantly improved when compared with preoperative ones in 2 groups (P lt; 0.05); and there was no significant differences between 2 groups at 2 weeks after operation and last follow-up (P gt; 0.05). Conclusion MI-TLIF by expandable tubular retractor is an available clinical choice in treating degenerative lumbar scoliosis stenosis. It can obtain the same effectiveness as the open surgery.
ObjectiveTo explore the effectiveness of self-made adjustable tractor for correction of inverted ni pple. MethodsBetween March 2005 and March 2011, 37 female patients with inverted ni pples (69 ni pples) underwent continuous traction with self-made adjustable tractor for 2 to 4 months. The age ranged from 18 to 46 years (mean, 23 years). Of 37 cases, 5 had unilateral inverted ni pple, and 32 had bilateral inverted ni pples, including 8 cases (15 ni pples) of mild inversion, 16 cases (30 ni pples) of moderate inversion, and 13 cases (24 ni pples) of severe inversion. The 2 cases (4 ni pples) recurred after traditional surgical method, and 1 case (2 ni pples) had infection because of severe inversion before traction. ResultsNo infection or hemodynamic disorder occurred during traction. All cases were followed up 6-12 months (mean, 8.2 months). Wound healed after traction in 1 patient (2 ni pples) with infection because of severe inversion; 2 recurrent cases (2 ni pples) were cured after re-traction; wire dislocation occurred in 1 case (1 ni pple), and was cured after changing traction position. The shape, sensation, and erectile function were normal after treatment with no scar. ConclusionContinuous traction with selfmade adjustable tractor is a good method for all the types of inverted ni pple. It is a simple, safe, effective, and minimally invasive method without scar.
ObjectiveTo explore the feasibility of decompression without gastric tube after minimally invasive esophageal cancer surgery.MethodsSeventy-two patients who underwent minimally invasive esophageal cancer resection at the Department of Thoracic Surgery, The Second Affiliated Hospital of Harbin Medical University from 2016 to 2018 were selected as a trial group including 68 males and 4 females with an average age of 58.5±7.9 years, who did not use gastric tube for gastrointestinal decompression after surgery. Seventy patients who underwent the same operation from 2013 to 2015 were selected as the control group, including 68 males and 2 females, with an average age of 59.1±6.9 years, who were indwelled with gastric tube for decompression after surgery. We observed and compared the intraoperative and postoperative indicators and complications of the two groups.ResultsThere were no significant differences between the two groups in operation time, intraoperative blood loss, postoperative level of serum albumin, postoperative nasal jejunal nutrition, whether to enter the ICU postoperatively, death within 30 days after surgery, anastomotic leakage, lung infection, vomiting, bloating or hoarseness (P>0.05). No gastroparesis occurred in either group. Compared with the control group, the recovery time of the bowel sounds and the first exhaust time after the indwelling in the trial group were significantly shorter, and the total hospitalization cost, the incidence of nausea, sore throat, cough, foreign body sensation and sputum difficulty were significantly lower (P<0.05).ConclusionIt is feasible to remove the gastric tube for gastrointestinal decompression after minimally invasive esophageal cancer surgery, which will not increase the incidence of postoperative complications, instead, accelerate the postoperative recovery of patients.
ObjectiveTo compare the early clinical and radiographic outcomes of hemiarthroplasty by a minimal invasive Supercap approach and by a conventional approach for elderly displaced femoral neck fractures. MethodsBetween January and June 2015, 70 geriatric patients with displaced femoral neck fracture underwent cementless bipolar hemiarthroplasty by minimally invasive Supercap approach (group A, n=35) or by posterolateral approach (group B, n=35). One patient was excluded from the study in group B because of too wide femur cavity. There was no significant difference in gender, age, body mass index, fracture cause, time from fracture to operation, fracture side, fracture classification, and preoperative visual analogue scale (VAS), and hemoglobin-level between the 2 groups (P > 0.05). The operation time, intraoperative blood loss, incision length, and complications were recorded. The early clinical evaluations included timed up and go test (TUG), hemoglobin-level, VAS score, and satisfaction. The anteroposterior and lateral X-ray films were taken to measure the stem alignment, difference in leg length, and difference in femoral offset. ResultsAll the patients were followed up 6-11 months (mean, 7.32 months). No patients died during follow-up. There was no significant difference in operation time and intraoperative blood loss between the 2 groups (P > 0.05). The incision length of group A was significantly smaller than that of group B (P < 0.05). One patient had delayed union of incision in group A (2.86%); 2 patients had deep vein thrombosis in group B (5.88%); and there was no significant difference in the complication rate (χ2=0.764, P=0.512). The postoperative hemoglobin level showed no significant difference between the 2 groups (P > 0.05). Group A had lower VAS score and higher subjective satisfaction than group B, showing significant difference at 1, 5, and 14 days after operation (P < 0.05). The TUG of group A was significantly shorter than that of group B at 5, 14, and 30 days (P < 0.05). There was no significant difference in femoral offset or leg length on the X-ray films (t=1.273, P=0.851; t=0.409, P=0.327). The good rate of stem alignment was 82.86% (29/35) in group A, and was 85.30% (29/34) in group B, showing no significant difference (χ2=0.584, P=0.497). ConclusionBoth minimal invasive Supercap approach and conventional posterolateral approach are effective and safe for elderly displaced femoral neck fractures in hemiarthroplasty. Supercap approach has the advantages of less trauma, pain relief, and improvement of mobility and rapid rehabilitation.
Objective To review the development of endoscopic techniques in breast surgery, focusing on their use in benign breast lump resection and breast-conserving surgery for cancer, and also summarize the development and application of these techniques in China, highlighting promotion and homogenization challenges and future directions. Methods A systematic review of relevant literature was conducted to trace the historical evolution, clinical applications, and related research of endoscopic techniques in breast surgery, emphasizing their advantages and disadvantages of endoscopic benign breast lump resection and breast-conserving surgery for cancer. Results Endoscopic benign breast lump resection and breast-conserving surgery for cancer have improved patients’ postoperative psychological health and quality of life, particularly in scar-free surgery. However, challenges such as limited intraoperative visibility and prolonged surgery time lead to controversy in clinical practice. Conclusion Despite significant advancements, endoscopic techniques in breast surgery also face challenges. Future efforts should focus on technological improvements and clinical research to address these issues, promoting widespread application and standardization. The key to future development lies in the promotion and homogenization of these technologies.
Objective To review the latest comparative research of minimally invasive transforaminal lumbar interbody fusion (TLIF) and traditional open approach. Methods The domestic and foreign literature concerning the comparative research of minimally invasive TLIF and traditional open TLIF was reviewed, then intraoperative indicators, length of hospitalization, effectiveness, complication, fusion rate, and the effect on paraspinal muscles were analyzed respectively. Results Minimally invasive TLIF has less blood loss and shorter length of hospitalization, but with longer operation and fluoroscopic time. Minimally invasive surgery has the same high fusion rate as open surgery, however, its effectiveness is not superior to open surgery, and complication rate is relatively higher. In the aspect of the effect on paraspinal muscles, in creatine kinase, multifidus cross-sectional area, and atrophy grading, minimally invasive surgery has no significant reduced damage on paraspinal muscles. Conclusion Minimally invasive TLIF is not significantly superior to open TLIF, and it does not reduce the paraspinal muscles injury. But prospective double-blind randomized control trials are still needed for further study.
