ObjectiveTo investigate the anatomical characteristics of breast lymphatic drainage in patients with breast cancer after injecting methylene blue and indocyanine green (ICG) into the intradermis of the areola.MethodsOne hundred and eighty-six patients with stage 0–Ⅱ breast cancer were collected. The sentinel lymph node (SLN) biopsy was performed by injecting methylene blue and ICG. At the same time, the number of sentinel lymphatic channel (SLC), origin angle, direction, and consistency were also studied.ResultsA total of 308 SLCs were successfully showed in the 186 patients and 679 SLNs were detected. The 95.8% (295/308) of SLCs and 93.1% (632/679) of SLNs were showed by combination in the methylene blue and ICG. The 46.8% (87/186) of patients had 1 SLC, the 40.9% (76/186) of patients had 2 SLCs, the 12.4% (23/186) of patients had 3 SLCs. The 82.8% (255/308) of SLCs flowed from the outer upper edge of the areola, the 3.2% (10/308) of SLCs flowed from the outer lower edge of the areola, the 14.0% (43/308) of SLCs flowed from the inner upper edge of the areola. The 89.9% (277/308) of the SLCs flowed mainly through the 0°—60° interval in the outer upper quadrant, 10.1% (31/308) of the SLCs flowed through the 61°—90° interval in the outer upper quadrant.ConclusionsThe consistency of SLC and SLN stained by the two tracers is good. The number of SLC is 1–3. The SLCs flow mainly through the 0°—60° interval in the outer upper quadrant of the breast, then flow into in the axilla and don’t flow into the internal mammary lymph nodes. The deep superficial lymphatic channels under the skin and the penetrating lymphatic channels can not be showed by ICG, but the SLN can be showed by it.
ObjectiveTo observe the impacts of initial therapy on clinical outcome of patients with community-acquired thoracic infection by retrospective analysis.
MethodsClinical data of acute community-acquired thoracic infection patients who met the British Thoracic Society diagnostic criteria were collected. The patients were divided into two groups according to whether adequate initial antibiotic therapy and pleural effusion drainage were performed, namely an adequate group (31 patients) and an inadequate group (17 patients). Clinical manifestations, inflammatory markers, hospital stay and hospital costs were analyzed between the two groups.
ResultsFor age, gender, infection sites, and coincident diseases, there were no significant differences between the two groups. Compared with the inadequate group, temperature of the adequate group was significantly decreased, especially on hospital day 5, 6, 7[(37.4±0.1)℃ vs. (38.3±0.2)℃, P < 0.001; (37.4±0.1)℃ vs. (37.9±0.1)℃, P < 0.05; (37.4±0.1)℃ vs. (38.1±0.2)℃, P < 0.01]. The level of serum C-reactive protein (CRP) in first week was also significantly reduced in the adequate group[(123.1±13.8) mg/L vs. (182.7±25.3) mg/L, P < 0.05]. However, there were no differences in white cell counts, percentage of neutrophils, or erythrocyte sedimentation rate between the two groups in six-week follow-up. The adequate group had shorter hospital stay[(25±4) days vs. (34±4) days, P < 0.05] and lower hospital costs[(28 367±3 328) yuan vs. (43 334±7 134) yuan, P < 0.05] compared with the inadequate group.
ConclusionsThe initial therapy with appropriate antibiotics and effective thoracic drainage can significantly decrease the temperature and CRP of patients with thoracic infection, as well as the cost of hospitalization and the length of stay. Our study reveals that the temperature which is lower than 37.5℃ on the 5th day of therapy and the CRP in the first follow-up week are sensitive predictors of initial treatment effect, which may be helpful to guide the following therapeutic strategies.
ObjectiveTo investigate the methods and effectiveness of one-stage operation for pelvis and acetabular fractures combined with Morel-Lavallée injury by internal fixation associated with vacuum sealing drainage (VSD).
MethodsBetween June 2008 and October 2012, 15 cases of pelvis and acetabular fractures combined with Morel-Lavallée injury were treated. There were 5 males and 10 females, aged from 18 to 67 years (mean, 36.8 years). Fractures were caused by traffic accident in 11 cases and crashing injury of heavy object in 4 cases. The time from injury to hospitalization was 3 hours to 9 days (mean, 5.4 days). Morel-Lavallée injury located in the above posterior superior iliac spine in 4 cases, greater trochanter in 7 cases, and anterior proximal thigh in 4 cases. In 10 cases complicated by pelvic fracture, there were 1 case of anteroposterior compression type, 3 cases of lateral compression type, 5 cases of vertical shear type, and 1 case of compound injury type; in 5 cases complicated by acetabular fracture, there were 1 case of transverse fracture, 1 case of posterior wall and posterior column fracture, 1 case of transverse acetabulum plus posterior wall fracture, and 2 cases of both columns fracture. Open reduction and internal fixation were used to treat pelvic and acetabular fractures, and VSD to treat Morel-Lavallée injury. When the drainage volume was less than 20 mL/d, interrupted wound suture or free skin grafting was performed.
ResultsThe hospitalization time was 16-31 days (mean, 20.8 days). Thirteen cases were followed up 4-16 months (mean, 7.8 months). The healing time of Morel-Lavallée injury was 16-36 days after operation (mean, 21.3 days). All the wounds had primary healing, and no infection occurred. The X-ray films showed that all fractures healed, with a mean healing time of 13.6 weeks (range, 11-18 weeks). At 6.5 months after operation, according to Majeed function scoring system in 8 cases of pelvic fracture, the results were excellent in 5 cases, good in 2 cases, and fair in 1 case; according to Harris hip scoring in 4 cases of acetabular fracture, the results were excellent in 2 cases, good in 1 case, and fair in 1 case.
ConclusionTo pelvis-acetabular fractures combined with Morel-Lavallée injury, internal fixation treatment for fracture and VSD for Morel-Lavallée injury not only can cure merge Morel-Lavallée injury effectively, but also can guarantee the operation timing and incision safty of the pelvis-acetabular fractures.
Three types of intestinal loops were used to reestablish the internal drainage of bile in 17 cases. The leeway derived from the peristaltic cycle of the intestinal loop for gastrointestinal reflux pressure, the cholangeitis after operation from reflux following choladocho-intestinal anastomosis could be avoided, and, naturally it had changed the traditional method of purèly blockade of the reflux, thus the result from treatment was far more satisfactory.
Objective
To investigate the value of applying closed continuous negative pressure drainage in preventing postoperative complications of inguinal hernia.
Methods
The clinical data of 107 adult male patients diagnosed with inguinal giant hernia (incarcerated 16 cases, non-incarcerated 91 cases) undergoing tension-free hernioplasty using the Ultrapro Hernia System (UHS) between April 2011 and June 2016 in our hospital were retrospective analyzed. Prophylactic use of antibiotics was not adopted except patients with incarcerated hernia, diabetes, or elderly. Multi-lateral hole plasma drainage tube were used in 61 patients, 46 cases without indwelling plasma tube. The postoperative scrotum pain, scrotal hematoma, scrotal effusion, and incision infection of two groups patients were observed.
Results
Of the 61 patients with plasma drainage, the mean drainage time was 2 days, the longest was 5 days. Postoperative scrotal pain was found in 2 cases (3.3%) without scrotal hematoma or scrotal effusion. Of the 2 patients, the drainage of 1 case was obstructed, the drainage was extubated and the patient was cured and discharged after 5 days by sucking the drainage tube using empty needle. The average hospital stay in this group was 4 days. Of the 46 patients without plasma drainage, 7 patients (15.2%) suffered scrotal pain, 7 patients (15.2%) suffered scrotal hematoma. The average hospital stay was 6 days. The incidence of scrotal pain and scrotal hematoma was significantly higher in patients without plasma drainage than those with drainage (P<0.05). The condition of scrotal hematoma would be improved after 1–3 times outpatient dressing change and repeated hematoma sucking. One case was not improved after repeated suction, the condition was improved after scrotum incision, drainage, and dressing.
Conclusion
Closed continuous negative pressure drainage potentially prevents oblique hernia pain and scrotal hematoma without increasing the incidence of incision infection or hospitalization time.
ObjectiveTo analyze the postoperative drainage volume and its influencing factors in lumbar posterior surgery.MethodsA total of 158 patients undergoing lumbar posterior surgery in West China Hospital, Sichuan University between October 2018 and June 2019 were retrospectively enrolled in this study. The data about general information and perioperative drainage were collected retrospectively according to recording tables and analyzed by SPSS (version 22) software. The drainage volume was presented with median (lower quartile, upper quartile).ResultsThe final average drainage volume was 360 (200, 650) mL, and the length of time for drainage tube placement was from 9 to187 hours with the median (lower quartile, upper quartile) of 61 (40, 86) hours. The result of multiple linear regression showed that immediate drainage volume when returning to the ward [non-standardized partial regression coefficient (b)=0.268, 95% confidence interval (CI) (0.191, 0.345), P<0.001], length of time for drainage tube placement [b=0.554, 95%CI (0.338, 0.769), P<0.001], intra-operative bleeding volume [b=0.161, 95%CI (0.044, 0.277), P=0.007], and surgical methods [Method 3 as the reference, Method 1: b=0.599, 95%CI (0.369, 0.828), P<0.001; Method 2: b=0.574, 95%CI (0.336, 0.812), P<0.001] were the main factors affecting the final drainage volume.ConclusionsThe final drainage volume of lumbar posterior surgery is so large that it should be paid attention to. It is also necessary to take effective interventions according to different surgical methods, intraoperative bleeding, immediate drainage when returning to the ward, length of time for drainage tube placement, and other different circumstances to reduce the drainage to achieve enhanced recovery after surgery.
