ObjectiveTo explore the diagnostic and therapeutic value of laparoscopy in acute abdomen.
MethodsRelated literatures were collected to analyze the advantages, the scope of application, and the effect on the body of laparo-scopy, and to clearly defined the indications of laparoscopy in acute abdomen and related taboos.
ResultsMost people could be tolerated for CO2 pneumoperitoneum. Laparoscopic surgery had a certain advantages compared with open surgery in the diagnosis and treatment. It was widely used in the diagnosis and treatment of acute abdomen.
ConclusionLaparo-scopic surgery is recommended for acute appendicitis, acute cholecystitis, peptic ulcer perforation, and so on, but it is still controversial in intestinal obstruction, intestinal diverticulum perforation, and the application of abdominal trauma, which need more randomized controlled studies comparing with open operation.

Followed up 16 cases for 6 to 12 months, the device was effective. CONCLUSION The skin stretching device is practical and effective in wound closure of skin defect.
Objective To investigate the causes of death and evaluation of injury severity in patients with thoracic trauma so as to enhance the diagnosis and treatment of thoracic trauma. Methods A retrospective study was carried out in 687 patients with thoracic trauma, which were divided into different groups according to their condition of injury (chest injury group and multiple injuries group) and outcome (survival group and death group) and penetrating into pleural cavity (penetrating injury group and blunt trauma group), then trauma scores(revised trauma score,abbreviated injury scale,injury severity score,probability of survival)were compared respectively. In addition, the highrisk causes of trauma death were analyzed. Results Among 687 cases, there are 488 cases with blunt trauma and 199 cases with penetrating injury. The causes of trauma death in blunt trauma group were brain injury (10 cases) and acute respiratory failure (6 cases) and multiple organ dysfunction syndrome (4 cases) and hypovolemic shock (1 case). The causes of trauma death in penetrating trauma group were hypovolemic shock (9 cases). There were statistically difference of trauma score in the death group and the survival group（GCS：t=4.648,P=0.000; RTS:t=4.382,P=0.000;thoracic AIS：t=2.296,P=0.027;ISS：t=4.871，P=0.000; Ps：t=4.254,P=0.000）. There was no statistically difference of thoracic AIS in the chest injury group and the multiple injuries group (t=0.723, P=34.567), and there were statistical significances in RTS（t=2.553,P=0.032）, ISS（t=10.776,P=0.000）, Ps（t=3.868,P=0.007）. There were statistically difference of RTS（t=3.161,P=0.007）and ISS （t=4.118,P=0.005） in the blunt trauma survival group and penetrating injury survival group, and there was no statistical significance in Ps（t=0.857,P=97.453）. The blunt trauma death group had statistical difference compared with penetrating injury death group in trauma score（GCS：t=4.016,P=0.001，RTS:t=3.168,P=0.006;thoracic AIS：t=2.303, P=0.043;ISS：t=4.218,P=0.002;Ps：t=4.624,P=0.001）. The mortality of trauma was gradually increased with the trauma scores. The mortality was 10.7% when whole ISS was 20.25. The mortality in penetrating injury group was higher than that in blunt trauma group with the same ISS between two groups. Conclusion Applying trauma score is conducive to the judgement of trauma severity and optimizing clinical treatment. The death causes in blunt trauma group were more complex than in penetrating injury group. Severe trauma and multiple injuries are the main death causes of thoracic trauma.
Objective To investigate the short-term effectiveness of Swanson artificial joint replacement in treating post-traumatic metacarpophalangeal joint stiffness. Methods Between August 2007 and May 2010, 11 cases (13 fingers) of metacarpophalangeal joint stiffness with soft tissue defects underwent Swanson artificial joint replacement. There were 7 males (9 fingers) and 4 females (4 fingers), aged 43 to 65 years with an average of 49 years. The involved fingers included 4 thumbs, 4 index fingers, 3 middle fingers, and 2 ring fingers. The types of injury included open and crush injury in 8 fingers, fracture of the metacarpophalangeal joint in 3 fingers, metacarpophalangeal joint severing in 2 fingers. The time from joint stiffness to hospitalization was 12 to 48 weeks (mean, 24 weeks). The joint activity was (136.82 ± 28.96)°. According to total active motion (TAM) assessment, included good in 1 finger, fair in 6 fingers, and poor in 6 fingers before operation. The activities of daily living were assessed by Sollerman score, which was 45.64 ± 11.04. The X-ray films and CT scan showed traumatic arthritis of the metacarpophalangeal joint. Results The incision healed by first intention. All patients were followed up 12 to 34 months (mean, 24.1 months). At last follow-up, the joint activity was (194.64 ± 28.86)°, showing significant difference when compared with preoperative value (t=25.214, P=0.000). According to TAM assessment, including excellent in 1 finger, good in 4 fingers, fair in 7 fingers, and poor in 1 finger. The Sollerman score was 67.45 ± 8.20 postoperatively, showing significant difference when compared with the preoperative score (t=10.470, P=0.000). X-ray examination showed no prosthesis fracture, periprosthetic fracture, or joint dislocation occurred at last follow-up. Conclusion Swanson artificial joint replacement can be appl ied to treat posttraumatic metacarpophalangeal joint stiffness, which can improve the joint activity and has satisfactory short-term effectiveness.
In order to preserve more normal tissue in situ in case of severe traumatic rupture of spleen, simultaneous ligation of splenic artery and vein was performed successfully on animals and then was applied for clinic use. The preserved splenic tissue all survivied and functioned well. Patients with severe traumatic rupture of spleen grade Ⅳ-Ⅴ were all cured by ligation of both the splenic artery and vein at the same time.
Form April 1991 to August 1994, ten cases of extensive soft tissue injury of the extremities with bone and tendons exposed were treated by emergency transfer of latissimus dorsi myocutaneous flaps. The types of the myocutaneous flap were as follows: with vascular pedicle in 1 case, free latissimus dorsi myocutaneous flap in 8 cases,and transfer of combined bilateral latissimus dorsi myocutaneous flaps in 1 case. There were 8 males and 2 females with the ages ranging from 7 to 44 years (an average of 24.4 years). The operations were all performed within 6 hours after trauma except in 1 case, due to its delayed arrival to our hospital, the operation was carried out 14 days after trauma. The results were as follows: total survival of the flap in 6 cases, necrosis of the distal portion of the skin of the flap in 3 cases and necrosis of a greater portion of the skin in one case who had been subjected the transfer of combined bilateral latissimus dorsi myocutaneous flap. but the deep muscle layerwas intact. However, the result was encouraging. The operative technique and the advantages of emergency coverage of the wound were discussed.
Fifteen rabbits were given a second degree scald on the back, then a large amount of fluid were given rapidly. In this way an acute diluted hyponatremia and a brain edema model were produced. In one group, the magnetotherapy was instituted immediately following the acut injury, while in the other group, it was started after the brain edema being developed. After giving a large quantity of fluid, the Na~+, CI~-, and K~+ concentrations in the blood were decreased and the quantity of water in the brain tissue was increased evidentely. The phenomena of neuron edema and widening of the perivascular space were also found. It was proved that the model of experimental brain edema could be produced on animals and the treatment and the prevention for brain edema could be obtained to advantage to certaiin degree. Also,it was better to use the magnetotherapy in brain edema as early as possidle.
Abstract For the purpose of studying the effects on wound healing of three new bioelectret composites (BC) which are composed ofcollagen polyvinyl alcohol and epidermal growth factor (EGF), 30 rabbits were divided into 5 groups. Three wounds in round shape (1.8 cm in diameter) were made in each side of the back of the rabbits. The wounds of 1～3 groups were treated by one of the three BC respectively, group 4 treated by SDAg, and group 5 were treated by Normal saline as control. From observation of the growth of the granulation tissue, the reepithelization and the pathological assessment, it was shown that the quality of wound healing in all BC treated wounds was better than that in SDAg or the control. It indicated that the BC benefited the wound healing, and this might also be due to its bioelectric effects and the direct effects from growth factor.
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.
