ObjectiveTo discuss the safety and feasibility of no chest tube (NCT) after thoracoscopic pneumonectomy.MethodsThe online databases including PubMed, EMbase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), WanFang Database, VIP, China Biology Medicine disc (CBMdisc) were searched by computer from inception to October 2020 to collect the research on NCT after thoracoscopic pneumonectomy. Two reviewers independently screened the literature, extracted the data, and evaluated the quality of the included studies. The RevMan 5.3 software was used for meta-analysis.ResultsA total of 17 studies were included. There were 12 cohort studies and 5 randomized controlled trials including 1 572 patients with 779 patients in the NCT group and 793 patients in the chest tube placement (CTP) group. Meta–analysis results showed that the length of postoperative hospital stay in the NCT group was shorter than that in the CTP group (SMD=–1.23, 95%CI –1.59 to –0.87, P<0.000 01). Patients in the NCT group experienced slighter pain than those in the CTP group at postoperative day (POD)1 (SMD=–0.97, 95%CI –1.42 to –0.53, P<0.000 1), and POD2 (SMD=–1.10, 95%CI –2.00 to –0.20, P=0.02), while no statistical difference was found between the two groups in the visual analogue scale of POD3 (SMD=–0.92, 95%CI –1.91 to 0.07, P=0.07). There was no statistical difference in the 30-day complication rate (RR=0.93, 95%CI 0.61 to 1.44, P=0.76), the rate of postoperative chest drainage (RR=1.51, 95%CI 0.68 to 3.37, P=0.31) or the rate of thoracocentesis (RR=2.81, 95%CI 0.91 to 8.64, P=0.07) between the two groups. No death occurred in the perioperative period in both groups.ConclusionIt is feasible and safe to omit the chest tube after thoracoscopic pneumonectomy for patients who meet the criteria.
Objective To explore the feasibil ity, indications, and effects of vacuum seal ing drainage (VSD) combined with flaps for repairing skin and soft tissue defects of lower l imbs. Methods From June 2006 to November 2009, 15 patients with skin and soft tissue defects of lower l imbs were treated with VSD combined with flaps (VSD group, n=5) and only flaps (non-VSD group, n=10). In VSD group, there were 3 males and 2 females with an average age of 46 years (range, 32-69 years), including 3 cases of traffic accident injury, 1 case of skin necrosis after amputation, and 1 case of plate exposureafter operation. The locations were lower leg in 1 case, ankle in 2 cases, dorsum of foot in 1 case, and forefoot in 1 case. The defect size ranged from 6.5 cm × 6.0 cm to 23.0 cm × 17.0 cm. The disease course ranged from 2 hours to 2 months. In non- VSD group, there were 5 males and 5 females with an average age of 50 years (range, 23-58 years), including 6 cases of traffic accident injury, 1 case of crush injury in earthquake, 1 case of osteomyel itis, and 2 cases of plate exposure after operation. The locations were lower leg in 1 case, ankle in 3 cases, forefeet and dorsum of feet in 4 cases, and heel in 2 cases. The defect size ranged from 4 cm × 4 cm to 20 cm × 12 cm. The disease course ranged from 1 hour to 2 months. There was no significant difference in general data between 2 groups (P gt; 0.05). Results In VSD group, the preoperative hospital ization days, postoperative hospital ization days, and total hospital ization days were (11.8 ± 9.5), (35.4 ± 28.3), and (47.2 ± 35.8) days, respectively; the size of flap was (232.8 ± 142.0) cm2; and the infection rate after VSD-use was 0. In non-VSD group, the preoperative hospital ization days, postoperative hospital ization days, and total hospital ization days were (25.8 ± 12.4), (33.9 ± 28.1), and (59.7 ± 32.4) days, respectively; the size of flap was (97.3 ± 93.6) cm2; and the infection rate after 8 to 14 days of regular therapy was 80%. There were significant differences in the preoperative hospital ization days and the size of flap between 2 groups (P lt; 0.05). All flaps were al ive except 3 partial necrosis (1 case in VSD group, 2 cases in non-VSD group). The 3 flaps healed by skin grafting and suturing. The donor sites healed by first intention. All patients were followed up 5-41 months (22.1 months on average). All flaps were good in color, texture, and wear abil ity. Conclusion It is effective to apply VSD combined with proper flap to repair skin and soft tissue defects of lower l imbs, which can cut down infection rate, improve blood supply, shorten the preoperative hospital ization days, and facil itate heal ing, but whether it can shorten the postoperative hospital ization days and total hospital ization days need further research.
Objective To retrieve, evaluate, and summarize evidence on the prevention and management of intracranial infections related to lumbar drainage (LD), in order to provide scientific references for clinical practice and decision-making. Methods The literature on the prevention and management of LD-related intracranial infections in LD-related websites and databases was systematically searched, with a search period from the establishment of databases to June 30, 2024. The included literature was evaluated for quality and integrated into evidence. Results A total of 9 articles were included, including 3 guidelines, 1 evidence summary, 1 expert consensus, 1 systematic review, and 3 original studies. A total of 30 pieces of evidence were formed, covering six aspects: risk management, catheter placement, catheter maintenance, extubation, diagnosis and treatment of intracranial infections, education and training. ConclusionsThe prevention and management of LD-related intracranial infections involve multiple pieces of evidence, and medical staff should selectively apply the best evidence based on patient and clinical conditions to reduce the incidence of intracranial infections and improve medical quality.
The comparison made between two experimental models with obstructive jaundice, which were newly established reversible model and traditional bile duct ligation and internal drainage model, showed that the new model was superior to the traditional one. This study suggests that the new model would be an ideal model, which could replace the traditional one for studying obstructive jaundice.
ObjectiveTo explore the clinical significance of detecting serum intact parathyroid hormone (iPTH) and drainage fluid parathyroid hormone (dPTH) after thyroidectomy in forecasting parathyroid function.MethodsThe clinical data of 95 thyroidectomy patients in the same treatment group from March 2018 to September 2018 were retrospectively analyzed, which in the Department of Thyroid-Breast Surgery, the Second Affiliated Hospital of Kunming Medical University. According to the surgical method, the patients were divided into 3 groups: isthmus and unilateral thyroidectomy (partial resection group, n=33), total thyroidectomy (total resection group, n=33) and total thyroidectomy and central lymph node excision (radical resection group, n=29). The negative pressure drainage tube was placed in the operative area. The iPTH and serum calcium were detected before and the first day after operation. The dPTH was detected in the first day and the second day after operation. Serum calcium, iPTH and dPTH were statistically analyzed.ResultsThere were no significant differences in operative time, hospital stay and blood loss between the total resection group and the radical resection group (P>0.05), but the partial resection group were all less than the other two groups (P<0.01). On the first day after operation, the iPTH in the three groups were lower than that before operation, and the iPTH was significantly decreased in the total resection group and the radical resection group, with statistically significant difference (P<0.05). The dPTH in the three groups were significantly increased on the first and second day after operation (P<0.05), but there was no statistically significant difference between the three groups (P>0.05). There was no statistically significant difference in serum calcium between the three groups on the first day after operation (P>0.05).ConclusionsThe levels of iPTH, dPTH and serum calcium after thyroidectomy can comprehensively forecast the parathyroid function. Preventive calcium supplementation can reduce the occurrence of postoperative symptomatic hypocalcemia, which is conducive to the recovery of parathyroid function.
Rupture is one of main complications of liver abscess. Seventy-seven patients with rupture of liver abscess are reviewed. Liver abscess may freely rupture into adjacent structures or organs or serous cavities and cause vatious complications. The causative factors of rupture of liver abscess in this series were late medical consultation in the course of the disease, delayed treatment due to misdiagnosis, and improper treatment. Measures that prevent rupture of liver abscess include raising clinical awareness of early diagnosis and timely effective drainage. The authors consider that transperitoneal surgical drainage is the best approach. Most patients with rupture of liver abscess should be treated by surgical drainage togather with transomental or transumbilital veno-catheterization for antibiotic infusion. Patients with rupture of liver abscess usually present a poor prognosis and a high mortality rate. The mortality in this group was 35.1%(27/77), which is closely related to the complications of the rupture of liver abscess.
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 explore the effectiveness of vacuum sealing drainage (VSD) combined with open bone graft for tibial traumatic osteomyelitis. MethodsBetween June 2007 and December 2012, 23 cases of tibial traumatic osteomyelitis were treated, including 15 males and 8 females with an average age of 32.5 years (range, 22-48 years). The time from injury to admission was 7-18 months (mean, 8.6 months). There was local bone scarring in 15 cases, the size ranged from 8 cm×4 cm to 15 cm×8 cm. The CT multi-planar reconstruction was carried out preoperatively. Eleven cases had segmental bone sclerosis with a length of 1.5 to 3.8 cm (mean, 2.6 cm); 12 cases had partial bone sclerosis with a range of 1/3 to 2/3 of the bone diameter. On the basis of complete debridement, infection was controlled by VSD; bone defect was repaired by VSD combined with open bone graft. After there was fresh granulation tissue, the wound was repaired by free skin graft or local skin flap transfer. ResultsNail infection occurred in 2 cases, which was cured after the use of antibiotics. The wound healed at the first stage after repairing. All cases were followed up 10-18 months (mean, 13.5 months). In 11 cases of segmental bone sclerosis, the infection control time was 7-14 days (mean, 8.8 days); the bone healing time was 32-40 weeks (mean, 34.4 weeks); and the frequency of VSD was 3-6 times (mean, 4.5 times). In 12 cases of partial bone sclerosis, the infection control time was 7-12 days (mean, 8.3 days); the bone healing time was 24-31 weeks (mean, 27.3 weeks); and the frequency of VSD was 3-5 times (mean, 3.6 times). Infection recurred in 1 case, and the patient gave up the therapy. No infection recurrence was observed in the other patients. ConclusionThe VSD combined with open bone graft is an effective method for the treatment of tibial traumatic osteomyelitis.
ObjectiveTo investigate value of drainage fluid amylase content and other risk factors in predicting clinically relevant postoperative pancreatic fistula (CR-POPF) after laparoscopic pancreaticoduodenectomy (LPD).MethodsThe clinical data of 166 patients who underwent LPD in this hospital from January 2017 to December 2019 were retrospectively analyzed. The independent risk factors of CR-POPF after LPD were analyzed. And the sensitivity and specificity of drainage fluid amylase content obtained on postoperative day 1 and 3 (Abbreviated as DFA1 and DFA3, respectively) in predicting CR-POPF by receiver operating characteristic (ROC) curve.ResultsA total of 166 patients underwent LPD were collected in this study. The CR-POPF occurred in 16 (9.6%) patients and all of them were grade B. The DFA1 (P=0.037), DFA3 (P<0.001), and positive bacterial culture of drainage fluid after operation (P=0.020) were the independent risk factors of CR-POPF after LPD (P<0.05) by the logistic regression multivariate analysis. The area under the ROC curve of the DFA1 and DFA3 in predicting CR-POPF was 0.880 [95%CI (0.812, 0.949)] and 0.912 [95%CI (0.853, 0.971)] respectively, and the corresponding best critical value was 3 925 and 939 U/L, and the sensitivity was 100% and 100%, specificity was 64.0% and 70.7%, respectively.ConclusionFor patients with DFA1>3 925 U/L, DFA3>939 U/L, and positive bacterial culture of drainage fluid after operation, preventive measures should be made to avoid CR-POPF.
ObjectiveTo investigate the effects of closed thoracic drainage with single tube or double tubes after video-assisted thoracoscopic lung volume reduction surgery.MethodsRetrospective analysis was performed on 50 patients (39 males, 11 females) who underwent three-port thoracoscopic lung volume reduction surgery in our hospital from January 2013 to March 2019. Twenty-five patients with single indwelling tube after surgery were divided into the observation group and 25 patients with double indwelling tubes were divided into the control group.ResultsThere was no significant difference in pulmonary retension on day 3 after surgery, postoperative complications, the patency rate of drainage tube before extubation, retention time or postoperative hospital stay (P>0.05). Postoperative pain and total amount of nonsteroidal analgesics use in the observation group was less than those in the control group (P<0.05). ConclusionIt is safe and effective to perform closed thoracic drainage with single indwelling tube after video-assisted thoracoscopic lung volume reduction surgery, which can significantly reduce the incidence of related adverse drug reactions and facilitate rapid postoperative rehabilitation with a reduction of postoperative pain and the use of analgesic drugs.
