The case of long-term complicated infectious mass on the inner thigh root after transobturator urethral sling is rare. This paper reported a case, who underwent a surgery of the "trans-obturator mid-urethral slings" for stress urinary incontinence 9 years ago. A mass on the root of the right thigh was found 3 months ago, accompanied with low fever. About 1cm tape was exposed on the front wall of the right side of the vagina. The patient underwent resection of the mass on the root of the right thigh and partial removal of the tape under spinal anesthesia. After one year’ follow-up, there was no significant change in urinary control ability compared with that before the operation.

Objective: To explore the effect of debridement combined with vacuum sealing drainage (VSD) on the treatment of severe infection in abdominal wall due to allogeneic umbilical cord embedded in abdominal wall for immunotherapy. Methods: From January 2015 to December 2016, 12 patients with severe infection in abdominal wall due to allogeneic umbilical cord embedded in abdominal wall for immunotherapy were admitted to our department. They were conducted with systemic anti-infective treatment, local debridement, and VSD. The wounds were continuously washed for 3 to 5 days after the VSD device installed, with negative pressure value from -16.0 to -12.0 kPa. The VSD device was removed 5 to 7 days later. Continue wound dressing by aseptic ribbon gauze was stuffed in the cavity, and the incision was sutured after the granulation tissue grew well in the cavity. Results: In all patients, allogeneic umbilical cords were completely removed and abdominal infection was cured. The wounds healed well, the sensory function of abdominal was normal, and the activity was not restricted. All the patients were followed up for 3 to 6 months with no reinfection or incisional hernia. Conclusions Embeding the whole allogeneic umbilical cord in abdominal wall for immunotherapy can lead to severe infection in abdominal wall. Abdominal infection can be cured by debridement combined with VSD with good clinical results.

Objective:To explore the effect of neurolysis and tendon transplantation in functional reconstruction of the upper limb with severe thermal crush injury.Methods:A retrospective case series study was conducted to analyze the clinical data of 12 patients with thermal crush injuries of the upper limb admitted to Changhai Hospital of Naval Medical University from January 2014 to December 2018. There were 9 males and 3 females, aged 22-54 years (mean, 38 years). The percentage of total body surface area (TBSA) burn ranged from 3% to 8% [(4.9±1.4)%], and wound depth was III degree. According to the damage condition of nerve/tendon and whether there was any dysfunction of the affected limb after wound healing, 12 patients received 2 to 4 times of neurolysis and tendon transplant-related surgeries, with an average surgery of 2.7 times. Among them, a total of 18 times of neurolysis were performed, including 7 times of radial neurolysis, 6 times of median nerve neurolysis and 5 times of ulnar neurolysis, and 14 times of tendon transplantation were done, including 6 times of anastomosis of superficial flexor tendon and long thumb extensor tendon, 5 times of tendon repair transplantation and 3 times of anastomosis of lateral wrist extensor tendon and long thumb extensor tendon. The time interval of each operation was 3-6 months [(4.5±1.0) months]. The Changhai pain ruler, disability of arm-shoulder-hand table (DASH) and joint activity assessment table were assessed before the first operation, 3 months and 6 months after the last operation.Results:All the patients were followed up for 6-12 months (mean, 9.2 months). The score of Changhai pain ruler in the affected limb improved from 3 (2, 3)points before surgery to 1 (0.5, 1)points 3 months after surgery and 1 (0, 1)points 6 months after surgery ( P<0.01). The score of DASH improved from (69.9±2.7) points before surgery to (35.1±1.7) points 3 months after surgery and (33.8±2.0) points 6 months after surgery ( P<0.01). The range of motion score was improved from (1.3±0.5) points before surgery to (2.4±0.5) points 3 months after surgery and (2.8±0.4) points 6 months after surgery ( P<0.01). Conclusion:Neurolysis and tendon transplantation in the treatment of severe thermal crush injuries of the upper limb can alleviate pain in the affected limbs, improve upper limb dysfunction, increase mobility of the palm and upper limb joints, and enhance the quality of life of the patients.

Objective:To investigate the clinical effects of negative pressure wound therapy (NPWT) in treating the poor healing of incisions after different abdominal operations.Methods:The retrospective observational study was conducted. From June 2019 to December 2020, 42 patients with poor healing of incisions after abdominal surgery were admitted to Center of Burns and Trauma of the First Affiliated Hospital of Naval Medical University, including 29 males and 13 females, aged 23-81 years. The disease course of poor healing of abdominal incision was 3-60 d. The preoperative examination of patients was completed after admission, and NPWT was used after debridement. According to the dehiscence level of incision, the negative pressure value of -10.64 to -6.65 kPa was set. The incisions were sutured in the second stage when the incisions had good blood circulation. The cause of abdominal surgery, the dehiscence level and the cause of poor healing of abdominal incision were investigated, and the final healing of abdominal incision and the occurrence of complication were observed.Results:The causes of abdominal operations in this group of patients who ocurred poor healing of abdominal incisions were ranked according to the composition ratio, with the top 4 causes being colon cancer (9 cases, accounting for 21.4%), bile duct disease (8 cases, accounting for 19.0%), liver cancer (5 cases, accounting for 11.9%), and appendicitis (4 cases, accounting for 9.5%). There were 25 cases (59.5%) with dehiscence of abdominal incision in the deep fascia layer, and the other 17 cases (40.5%) with dehiscence of abdominal incision in the superficial fascia layer. The causes of poor healing of abdominal incision were ranked according to the composition ratio, with the top 3 causes being infection (24 cases, accounting for 57.1%), fat liquefaction (11 cases, accounting for 26.2%), and suture reaction (5 cases, accounting for 11.9%). The blood circulation in 40 patients was improved after being treated with NPWT, and the incisions were sutured in the second stage. The incisions healed well when the suture lines were removed in the second to third week. Intestinal fistula and bile leakage developed during the NPWT treatment, respectively in the other 2 patients, in which negative pressure equipment was removed subsequently, and the incisions healed after adequate drainage and conventional dressing changes.Conclusions:NPWT is effective in treating poor healing of abdominal incision after different abdominal surgeries. The clinicians need to comprehensively assess the patient's condition to determine when and how to use NPWT to avoid the occurrence of intestinal fistula, bile leakage, and other complications.
