Objective To observe the operative technique and cl inical effects of hidden tension suture after tibiofibular fracture fixation with absorbable thread. Methods From October 2003 to October 2008, 203 patients (220 sides) with tibiofibular fracture underwent hidden tension suture (test group, 102 cases of 112 sides) and the common interrupted suture (control group, 101 cases of 108 sides), including 179 males and 24 females with an median age of 36 years (3-75 years). Fracture was caused by traffic accident in 170 cases, by heavy bruise in 21 cases, and by fall ing from height in 12 cases. Therewere 186 cases of single-side fracture, and 17 cases of double-side fracture. Of them, 127 sides were closed fracture, and 93 sides were open fracture (including 38 sides of type I, 45 sides of type II, and 10 sides of type IIIA according to Gustilo classification for the open fracture). The locations were upper tibia in 55 sides, middle tibia in 126 sides, and lower tibia in 39 sides. The X-ray films showed that there were transverse fractures in 65 sides, obl ique fractures in 53 sides, spiral fractures in 45 sides, and comminuted fractures in 57 sides. No blood vessel injury, osteofascial compartment syndrome and pressure syndrome were observed. The time from injury to operation was 2 hours to 7 days with an average of 2 days. Of 220 sides, 45 sides were fixed by interlocking nails, others by internal steel plate. Results In control group, heal ing by first intention was achieved in 70 cases (69.3%) and heal ing by secondary intention in 31 cases (30.7%); in test group, heal ing by first intention was achieved in 93 cases (91.2%) and heal ing by secondary intention in 9 cases (8.8%); and showing significant difference (P lt; 0.05). All patients were followed up for 6 months to 2 years (average 9 months). No compl ication occurred in test group, and scar was obvious in the control group. Conclusion The hidden tension suture with absorbable thread can be a good alternative for the incision heal ing after tibiofibular fracture fixation. It deals with the problems of the incision tension and difficult-to-suture, and is good for the incision heal ing after operation.
Objective To investigate the prevention of gangrene of exteriorized colon following transabdomino-perineal saving sphincter resection of rectal cancer. Methods From Aug. 1988 to Feb. 2000, 46 cases of cancer of the rectum were treated by transabdominoperineal saving sphincter with severing the anal sphincters and anorectal ring. During this procedure the anal sphincters and anorectal ring were severed to prevent gangrene of the exteriorized colon. Results In these cases, the exteriorized sigmoid colon had good blood supply and no gangrene was found. Conclusion This method can effectively prevent the gangrene of exteriorized sigmoid colon stump and gives no permanent fecal incontinence.
ObjectiveTo discuss the effect of three different ways of annulus fibrosus incision on the biomechanical strength of intervertebral disc.
MethodsA total of 30 goats underwent intervertebral disc nucleus pulposus extraction at L3, 4 and L4, 5 by the working channel in group A (n=10), by circular incision in group B (n=10), and by square incision in group C (n=10). The body weight, male and female ratio, age, intraoperative blood loss, and wound healing time were recorded and compared among 3 groups. The survival rate and wound healing situation were observed after operation. At 24 weeks after operation, the goats were sacrificed, MRI images were taken to observe the signal intensity of nucleus pulposus. The disc height of L3, 4 and L4, 5 was measured to calculate the loss of disc height; biomechanical test was used to assess the strength of the disc and anulus. Histological staining was also conducted to observe the repair effect at L4, 5.
ResultsThere was no significant difference in body weight, male to female ratio, age, intraoperative blood loss, and wound healing time among groups (P>0.05). All goats survived to the end of the experiment. MRI examination showed decreased signal intensity in 3 groups, indicating intervertebral disc degeneration. According to modified Thompson classification method, the degree of intervertebral disc degeneration of group A was significantly higher than that of groups B and C (P<0.05), but no significant difference was found between groups B and C (P>0.05). Difference was not significant in intervertebral space height before operation among 3 groups (P>0.05). But after 24 weeks, the intervertebral space height in group A was significantly higher than that in groups B and C (P<0.05), and the intervertebral space height loss in group A was significantly lower than that in groups B and C (P<0.05). The biomechanical strength in group A was also significantly higher than that in groups B and C (P<0.05), but no significant difference was found between group B and group C (P>0.05). HE and Masson staining showed good continuity of annulus fibrosus and clear layers in group A; poor continuity of annulus fibrosus and obvious scar tissues were observed in groups B and C.
ConclusionApplication of working channel may have less destruction of annulus fibrosus, it plays a positive role in the maintenance of biomechanical strength and repair of annulus fibrosus.
Objective Mesh infection may occur after incisional hernia repair using prosthetic mesh. Preparation of antibiotics-bonded meshes to prevent infection is one of the solutions. To evaluate the anti-infection effect of polypropylene mesh bonded norvancomycin slow-release microsphere by preparing the rat model of incisional hernia repair contaminatedwith Staphylococcus aureus. Methods The norvancomycin slow-release microspheres were prepared by emulsion and solvent evaporation method and they were bonded to polypropylene mesh (50 mg/mesh). The appearance of the microspheres was observed using scanning electronic microscope (SEM). The content of norvancomycin in microspheres and the release rate of the norvancomycin in norvancomycin-bonded polypropylene mesh were detected using high performance l iquid chromatography method. The rat models of incisional hernia were developed in 40 healthy Sprague Dawley rats, aged 10-11 weeks and weighing 200-250 g. The rats were divided randomly into the experimental group (norvancomycin-bonded polypropylene mesh repair, n=20) and the control group (polypropylene mesh repair, n=20). And then the mesh was contaminated with Staphylococcus aureus. The wound heal ing was observed after operation. At 3 weeks after operation, the mesh and the tissue around the mesh were harvested to perform histological observation and to classify the inflammatory reaction degree. Results The norvancomycin microsphere had integrated appearance and smooth surface with uniform particle diameter, 64% of particlediameter at 60 to 100 μm, and the loading-capacity of norvancomycin was 19.79%. The norvancomycin-bonded polypropylene patch had well-distributed surface and the loading-capacity of norvancomycin was (7.90 ± 0.85) mg/cm2. The release time of norvancomycin in vitro could last above 28 days and the accumulative release rate was 72.6%. The rats of 2 groups all survived to experiment completion. Wound infection occurred in 2 rats of the experimental group (10%) and 20 rats of the control group (100%), showing significant difference (χ2=32.727 3, P=0.000 0). The inflammatory reaction in experimental group was not obvious, grade I in 16 rats and grade II in 4 rats, and numerous inflammatory cell infiltration occurred in the control group, grade II in 3 rats and grade III in 17 rats, showing significant difference (Z=32.314, P=0.000). Conclusion The polypropylene mesh bonded norvancomycin slow-release microsphere has definite anti-infection effect in rat model of incisional hernia repair contaminated by Staphylococcus aureus.

ObjectiveTo evaluate the value of incision closure device in laparoscopic cholecystolithotomy.
MethodsThe clinical data of 130 patients underwent laparoscopic cholecystectomy from Oct. 2014 to Feb. 2015 were retrospectively analyzed. According to the methods of gallbladder suture, 130 cases were divided into two groups, 72 cases underwent traditional manual suture (MS group), and 58 cases underwent incision closure device (ICD group). The operative time, postoperative gastrointestinal function recovery time, bleeding volume, postoperative hospitalization time, hospitalization expenses, complications, and postoperative 6-12 months follow-up of patients in 2 groups were observed.Results One hundred and thirty cases were performed laparoscopic cholecystolithotomy successfully. The operative time and postoperative gastrointestinal function recovery time of ICD group were significantly shorter than those of MS group, the difference was statistically significant (P < 0.05). The hospitalization expenses of the patients in ICD group were significantly higher than those in the MD group (P < 0.05). There were no significant difference between the two groups in the bleeding volume and postoperative hospital stay (P > 0.05). The patients were followed up for 6-12 months, with an average of 8 months, and no complications occurred and stone recurrence.
ConclusionIncision closure device can shorten the time of laparoscopic cholecystolithotomy and postoperative recovery of gastrointestinal function, but the cost is higher. Next development, still need decrease the expend and strengthen clinical promotion.
Objective To summarize the surgical technique and curative effect of laparoscopic repair for suprapubic incisional hernia using composite patch. Methods The clinical data of 25 cases performed laparoscopic repair of suprapubic incisional hernia using composite patch from March 2007 to October 2010 were reviewed retrospectively. There were 13 males and 12 females， and aged 35-83 years （median age was 52 years）. Among them 2 patients were recurrences. The distance between the lower margin of hernia defect and pubic arc was less than 5 cm. The composite patch was fixed to the abdominal wall using spiral tacks （Protack） in direct vision. The lower margin of the patch was lower to the pubic arc in 2 cm， and to be fixed to the pubic arc and bilateral pectineal ligament， and it should be extended. Results Laparoscopic repair were successfully performed in all patients without convert to open repair. The max diameter of the hernia ring was 6.1-12.5cm and the average was 9.5 cm. The average operating time was 128 min （ranging from 90 to 180 min）. And the total complication rate was 28% （7/25）， including bladder damage during operation in 1 case， wound seroma upon the patch in 4 cases and cured by aspiration， pain in the operative area and disappeared within one month without intervention in 1 case. Twenty-two patients were followed-up with a follow-up rate of 88%. During a follow-up range of 6-48 months（average 30 months）， one case recurrence occurred in 2 months after the repair with the recurrent rate of 4%. Conclusions Laparoscopic repair of suprapubic incisional hernia is a safe and feasible technique， and the patch should cover and exceed the margin of the defect for 5 cm in all direction. The lower margin of the patch should be fixed to the bilateral pectineal ligament so as to strengthen the fix， and lower the recurrence rate.

ObjectiveTo explore the clinical effectiveness of two kinds of treatment methods to nurse wound after tracheotomy.
MethodsWe collected 108 cases and randomly divided them into two groups between March 2012 and May 2013. The experimental group (n=52) received tracheotomy care with PermaFoam dressing, while the control group (n=56) was treated with traditional sterile absorbent gauze. We analyzed the differences in terms of infection of wound, errhysis and frequency of dressing changes between the two groups.
ResultsThe experimental group had a lower rate of wound infection than the control group (P<0.05). Moreover, the experimental group was superior to the control group in the total number of dressing changes, wound redness and oozing (P<0.05).
ConclusionPermaFoam dressing can reduce wound complications and frequency of dressing changes effectively. It is easy to operate, and can reduce the workload of clinical nursing, and deserves clinical application.
Objective To explore the incidence of postoperative recurrence of abdominal incisional hernia and its related risk factors. Methods The clinical data of 213 patients with abdominal incisional hernia treated in the General Surgery of Shaanxi Provincial People’s Hospital from January 2015 to December 2019 were collected retrospectively, and the incidence of postoperative recurrence of abdominal incisional hernia and its related influencing factors were analyzed. Results A total of 213 patients underwent a complete follow-up. The follow-up time was 3 to 60 months, and the median follow-up time was 46 months. A total of 24 cases (11.27%) of hernia recurred after surgery. The univariate analysis results showed that body mass index (BMI), hernia ring size, incarceration, recurrent hernia, history of multiple abdominal operations, postoperative incision complications, factors such as increased abdominal pressure, and whether the patch were used for postoperative recurrence of abdominal incisional hernia influences (P<0.05). Further logistic multi-factor analysis results showed that BMI [OR=1.14, 95%CI (1.01, 1.29), P=0.040], incarcerated hernia [OR=8.94, 95%CI (1.94, 40.98), P=0.005], recurrent hernia [OR=10.91, 95%CI (2.09, 56.84), P=0.005], and hernia ring size [OR=1.15, 95%CI (1.03, 1.28), P=0.010] were related to the recurrence of abdominal incisional hernia after surgery (P<0.05). Conclusions The risk factors for hernia recurrence after abdominal incisional hernia repair include recurrent hernia, incarcerated hernia, hernia ring size, and BMI. For patients with high-risk factors, corresponding measures should be taken to prevent hernia recurrence.
