ObjectiveTo evaluate the safety and advantages of modified Bacon one-time operation in laparoscopic radical resection for ultra-low rectal cancer.MethodsThe medical records of all patients who underwent laparoscopic modified Bacon procedure for ultra-low rectal cancer treated by Professor SONG Junmin Medical Group of our department from August 2018 to June 2020 were analyzed retrospectively. According to the different methods during the operation, the patients were divided into a modified Bacon one-time operation group (modified Bacon group, n=26) and a Bacon secondary operation group (traditional Bacon group, n=33). The perioperative period data and follow-up results were observed and compared.ResultsA total of 59 ptients were collected, including 26 cases in the modified Bacon group and 33 cases in the traditional Bacon group. There were no significant differences in gender composition, age, etc. baseline data between the two groups (P>0.05). All surgery were successfully completed. There were no conversion to laparotomy, intraoperative or postoperative massive bleeding, severe infection and other serious complications and perioperative period death. The incidence of anastomotic leakage in the modified Bacon group was lower than that of the traditional Bacon group [0.0% (0/26) versus 18.2% (6/33), P=0.030]. There were no significant differences in the incidences of postoperative anastomotic bleeding, anastomotic stricture, rectal irritation, and external intestinal necrosis between the two groups (P>0.05). And the number of dissected lymph nodes, operation time, intraoperative blood loss, the first exhaust time, and postoperative hospital stay had no significant differences between the two groups (P>0.05). There were no significant differences in the severity degree and total score of low anterior rectectomy syndrome (LARS) between the two groups at 3 and 6 months after operation (P>0.05). However, the total LARS score at 6 months after operation was lower than that at 3 months in the same group (P<0.001). By the end of the last follow-up (January 2021), there was no obvious difference in the anal shape between the two kinds of surgery. There was no recurrence or death during the follow-up period.ConclusionModified Bacon one-time operation for ultra-low rectal cancer is safe and feasible, which could achieve natural orififice specimen extraction surgery and ultra-low limit sphincter preservation, reduce occurrence of postoperative anastomotic leakage and external intestinal necrosis, times of operation, and shorten total length of stay and reduce total cost of hospitalization.
Objective To evaluate the effect and safety of infantile femoral vein blood sampling with vacuum versus disposable needle. Methods Such databases as VIP, CNKI, CBM, Google Academic and Wanfang data were searched to collect the randomized controlled trials (RCTs) about infantile femoral vein blood sampling with vacuum versus disposable needle published from January 2000 to July 2010. The studies were screened according to the inclusive and exclusive criteria, the data were extracted, the methodology quality was assessed, and meta-analysis was conducted by using RevMan 5.0 software. Results A total of 15 RCTs were included. Of 3 490 patients in all, 1 770 were in the treatment group and 1 726 were in the control group. The baseline conditions were reported in 14 studies, and the random methods were mentioned in 11 RCTs. All studies didn’t report the allocation concealment and blind method. Only 2 RCTs reported separately that, the degree of neonatal pain was lower in the treatment group (Plt;0.01), and the satisfaction of parents was higher in the treatment group (Plt;0.01). Four RCTs compared the sampling time between the two groups without meta-analysis mentioned due to the disunity of standard, only the descriptive outcomes showed a shorter time in the treatment group. The meta-analysis showed that, compared with the control group, the reject rate of sample quality was lower (RR=0.20, 95%CI 0.15 to 0.26), the success rate of one time sampling was higher (RR=1.20, 95%CI 1.16 to 1.24), the injury of local tissue was slighter (RR=0.62, 95%CI 0.45 to 0.86), and the iatrogenic contamination was lower (RR=0.62, 95%CI 0.45 to 0.86) in the treatment group. Conclusion This review shows that the vacuum sampling is superior to the disposable needle sampling for domestic infantile femoral vein blood collection. Due to the low quality of the included studies with high possibility of bias, this conclusion needs to be further verified by performing more high-quality studies.
Objective To observe the effectiveness of disposable skin stretch closure in the treatment of wounds with skin and soft tissue defects that were difficult to close. Methods The clinical data of 13 patients with skin and soft tissue defects that were difficult to close treated with disposable skin stretch closure and met the selection criteria between July 2021 and February 2022 were retrospectively reviewed. There were 9 males and 4 females, the age ranged from 15 to 71 years with a mean of 39.8 years. The causes of injury included falling injury in 5 patients, traffic accident injury in 5 patients, and falling from height injury in 3 patients. The causes of skin soft tissue defects included open fractures in 4 patients, wound infection in 4 patients, osteomyelitis in 3 patients, degloving injury in 1 patient, and necrosis of skin graft in 1 patient. The injury was located at calf in 8 patients, calcaneus in 3 patients, pelvis in 1 patient, and plantar in 1 patient. The skin and soft tissue defects ranged from 5.0 cm×2.0 cm to 10.5 cm×6.5 cm. Wound conditions (wound closure and wound healing) and the presence or absence of complications were recorded. Results All 13 patients were followed up 32-225 days with a median of 164 days. The wound closure time ranged from 5 to 14 days, with a mean of 8.8 days. The wound closure speed ranged from 0.7 to 13.7 cm2/day, with a mean of 3.6 cm2/day. All wounds healed at grade A, and no complication such as skin edge injury, wound necrosis, infection, dehiscence, and edema occurred. No patient complained of pain or discomfort, and no obvious scarring was found during follow-up. The wound healing time ranged from 17 to 28 days, with a mean of 21.7 days. One of them was transferred to other department due to lung cancer condition changes after using disposable skin stretch closure, and the wound had directly healed without suturing at 17 days after operation. Conclusion The effectiveness of disposable skin stretch closure in the treatment of wounds with skin and soft tissue defects that were difficult to close was exact, with short wound closure time, few complications, and easy operation.
ObjectiveTo investigate the clinical effect of No. 8 blood collection needles in connecting broken balloon tubes. MethodsThirty-six patients who underwent mechanical ventilation in the Intensive Care Unit between January 2010 and December 2013 were included as the study subjects. We divided them into two groups. Patients who had accidental rupture of balloon tube during intubation were regarded as the trial group, while those with normal ventilation were regarded as the control group, with each group having 18 patients. The trial group used No. 8 disposable blood collection needles to connect the balloon tubes. Pressure gauge produced in Germany was used to measure the balloon pressure continuously for four hours. Balloon pressure level, balloon leakage and tube dislocation within 24 hours were observed. ResultsThe balloon pressure at different time periods was not significantly different between the two groups (P > 0.05). The leakage rate and complication rate were also not significantly different between the two groups (P > 0.05). ConclusionsUsing No. 8 blood collection needles for connecting broken balloon tubes is effective, easy, and convenient, and the balloon can be maintained at a constant pressure. It solved many previous clinical problems such as high cost, high complication rate, high death rate and medical disputes.
The quality of disinfectant, disinfection devices and disposable medical devices is closely related to the patients' safety. Hospital infection management department must carry out the audit responsibilities for qualification documents of disinfectant, disinfection devices and disposable medical devices, to guarantee legality, safety and effectiveness of products used in hospital. This paper mainly introduces the implementation of qualification documents audit in West China Hospital, Sichuan University, including system construction, process reengineering, documents audit scope and key points, and document management.
