ABSTRACT

Objective:To evaluate trans-artery pressure perfusion autologous transfusion for laparoscopic splenectomy and pericardial devascularization (LSPD).Methods:The clinical data of patients with laparoscopic splenectomy in Zhejiang Provincial People′s Hospital in recent 3 years were reviewed. The therapeutic effects of 30 LSPD cases with trans-artery pressure perfusion (observation group) and 30 radical LSPD cases (control group) were compared and analyzed.Results:There was no significant difference in age, sex, preoperative liver function grade and spleen volume between the two groups ( P>0.05). All 60 patients completed laparoscopic splenectomy without conversion to laparotomy or death. There was no significant difference in liver function, operation time and intraoperative bleeding between the observation group and the control group ( P>0.05), and there was also no significant difference in blood transfusion, postoperative complications and hospital stay ( P>0.05). The hemoglobin level in the observation group was significantly higher than that in the control group ( P<0.05). Conclusions:Laparoscopic splenectomy and pericardial devascularization with trans-artery pressure perfusion autologous transfusion can increase post-operative hemoglobin value effectively.

ABSTRACT

To investigate the feasibility and clinical effects of lobulated free latissimus dorsi flap in repairing severe shank trauma with irregular soft tissue defect. Methods Eight patients with soft tissue defect of shank due to trauma were treated from February, 2013 to November, 2018, which were 5 males and 3 females. All wounds were irregular.The size of soft tissue defect ranged from 11.0 cm×15.0 cm to 15.0 cm×23.0 cm, with different degrees exposure of deep tissue such as bone and tendon. Five cases out of 8 were infected wound, 3 cases of which had internal fixation bracket exposed. Five infected wounds were firstly treated with negative pressure after debride-ment, then repaired with flap transplantation until the infection were completely controlled. Other wounds were re-paired directly after debridement. The free lobulated latissimus dorsi flap was designed and applied to repair the ir-regular soft tissue defect of shank.The lobulated latissimus dorsi flap with the outer branch of the thoracodorsal artery ranged from 14.0 cm×7.0 cm to 24.0 cm×8.5 cm.The lobulated latissimus dorsi flap with the inner branch of the tho-racodorsal artery ranged from 10.0 cm×5.0 cm to 15.0 cm×7.0 cm. When cutting the flap, the branch vessels should be protected to insure the continuity of the thoracodorsal artery. After spliced the 2 lobulated flaps, the thoracodorsal arteriovenous was anastomosed with the recipient region arteriovenous. All the donor sites were sutured directly. All patients were followed-up by outpatient and telephone regularly. Results Seven flaps survived well.Only 1 case of partial necrosis appeared at the distal edge of the lobulated flap and healed after wound care. All patients were fol-lowed-up from 3 to 30 months, averaged of 14 months. The texture of flap was flexible and the appearance was well. Only a linear scar was left in the donor site. The shoulder joint retained good mobility. Conclusion The lobulated latissimus dorsi flap has rich blood supply, concealed donor area and high survival rate after transplantation, which can flexibly repair the irregular soft tissue defect of the shank, and effectively prettify the appearance of the recipient area. This strategy has little effect on the appearance and function of the donor area, and worthy of promoting in clinic.

ABSTRACT

Objective To investigate the efficacy of decompressive craniectomy (DC) combined with ipsilateral external ventricular drainage (iEVD) for severe traumatic brain injury (sTBI). Methods A retrospective case control study was performed on the clinical data of 54 sTBI patients admitted to the First People's Hospital of Taizhou from January 2015 to March 2018. There were 38 males and 18 females, aged 18-72 years [ (51. 8 ± 15. 4)years]. The Glasgow Coma Scale (GCS) of patients ranged from 3 to 8 points. Among 54 patients, 27 received DC treatment, including 18 males and nine females aged (50. 1 ± 2. 9)years (DC group);27 patients received DC combined with iEVD, including 18 males and nine females aged (53. 4 ± 3. 1) years (DC-iEVD group). Intracranial pressure after surgery and complications ( hydrocephalus and subdural hygroma) 2 weeks after surgery, andModified Rankin Scale (mRS) 3 months after surgery were compared between the two groups. Results All patients were followed up for 2.5-4 months [(3.0 ±0.8)months]. No significant difference was found in intracranial pressure at postoperative 12 hours and 24 hours between the two groups (P>0. 05). However, the intracranial pressure of DC-iEVD group were significantly lower than those of DC group at 36, 48, 60 and 72 hours after operation (P<0. 05). The hydrocephalus incidence 2 weeks after surgery of DC-iEVD group was 15% (4/27), while that of DC group was 7% (2/27)(P >0. 05). The subdural effusion incidence 2 weeks after surgery of DC-iEVD group was 19% (5/27), while that of DC group was 44% (12/27) (P<0. 05). According to mRS, patients with good outcome in DC-iEVD group accounted for 63%(17/27) while the ratio was 44% (12/27) in DC group. The prognosis of DC-iEVD group was slightly better than that of DC group, but the difference was not statistically significant(P>0. 05). Conclusion For sTBI, combined use of DC and iEVD can better control intracranial pressure and reduce the occurrence of subdural effusion.

ABSTRACT

Objective@#To summarize the measures and experience in diagnosis and treatment of extremely severe burn patients with severe inhalation injury in dust explosion accident.@*Methods@#The medical records of 13 patients with extremely severe burn complicated with severe inhalation injury in August 2nd Kunshan factory aluminum dust explosion accident who were treated at the First Affiliated Hospital of Soochow University (hereinafter referred to as our hospital) on August 2nd, 2014, were retrospectively analyzed. All the patients were transferred to our hospital 3-8 hours after injury under the condition of inhalation of pure oxygen. Twelve patients underwent tracheotomy within 5 hours after admission, while 1 patient underwent tracheotomy before admission. All the patients were in ventilator-assisted respiration, with synchronized intermittent mandatory ventilation combined with positive end expiratory pressure. All the patients underwent thorax or limbs escharotomy on the second day after admission, so as to reduce the restrictive ventilatory dysfunction caused by the contraction of thorax eschar and the terminal circulation disorder caused by the contraction of limbs eschar. All the patients underwent electronic bronchoscopy within 48 hours after admission, airway secretion were cleared and airway lavage were carried out under electronic bronchoscope according to the patients′ condition, and the sputum, lavage solution, pathological tissue were collected for microbiological culture. All the patients underwent chest X-ray examination on the second day after admission and reexamination as required. Patients were all treated with a combination of broad-spectrum antibiotics early after admission to control lung and systemic infection. One patient was treated with extracorporeal membrane oxygenation for acute respiratory distress syndrome 1 week after admission.@*Results@#One patient suffered from cardiopulmonary arrest during tracheotomy, which recovered autonomous respiration and cardiac impulse after cardiopulmonary resuscitation. Three patients showed decreased pulse oxygen saturation (SpO2) within 48 hours after injury, and the SpO2 returned to normal after sputum aspiration, scab removal and lavage under electronic bronchoscope. During the course of disease, bacteria were cultured from wound exudate of 7 patients, bacteremia occurred in 10 patients, and sputum microbiological culture results of 13 patients were positive. Eight of the 13 patients in this group survived, and 5 died. One patient died 19 days after injury, and 4 patients died 33-46 days after injury. The main cause of death was multiple organ dysfunction syndrome induced by severe septic shock eventually.@*Conclusions@#For this batch of patients with extremely severe burn complicated with severe inhalation injury caused by dust explosion accident, the treatment and cure measures including early definite diagnosis and timely tracheotomy, the application of effective ventilation, the effective treatment of respiratory system complications, and rational use of antibiotics for the control of lung infection obtained quite good curative effect.

ABSTRACT

Objective@#To explore the clinical effects of adjacent fasciocutaneous flaps in repairing small wounds with bone or steel plate exposure in anterior tibia.@*Methods@#Twelve patients with small wounds of bone or steel plate exposure in anterior tibia covering area of 2 cm×2 cm to 5 cm×3 cm were admitted to our unit from January 2014 to December 2016. A circular or elliptical adjacent fasciocutaneous flap was designed on the normal skin located at the inside or outside of the wound according to the size of wound after thorough debridement. The pedicle of the flap was located at the proximal end and transferred through the subcutaneous tunnel to cover the wound. The sizes of flaps were 3 cm×3 cm to 6 cm×4 cm. Flaps were fixed with interrupted sutures and drainage rubber sheets were placed under the flaps. The drainage rubber sheets were removed within 24 to 48 hours. The donor area was repaired by medium-thickness skin graft collected from homolateral outer thigh.@*Results@#All the flaps of 9 patients survived. Two patients had necrosis at the distal end of the flaps and were cured by changing dressing. One patient had tension blisters on the flap and was cured by removing blisters and improving microcirculation. All patients were followed up for 3 months, and the flaps were good in blood supply, appearance, and color, with hypaesthesia.@*Conclusions@#Repair of small wounds with bone or steel plate exposure in anterior tibia by adjacent fasciocutaneous flap is simple in surgical procedure and does not damage the well-known blood vessels, and the appearance, texture, and thickness of flaps are close to the skin of anterior tibia region. It is a good choice for repairing this kind of wounds and worth promoting in clinic.
