  • Preventive effect of continuous dissecting suture and silver ion dressing on incisional surgical site infection after ostomy for colorectal surgery and influencing factors of incisional surgical site infection

    Objective To compare preventive effect between continuous dissecting suture and traditional interrupted suture, silver ion dressing and traditional dressing, on the incisional surgical site infection (SSI) after ostomy for colorectal surgery, and to explore the influencing factors of SSI. Methods ① Sixty patients underwent the firstly elective open ostomy for colorectal surgery, who were treated in Department of Colorectal Tumor Surgery and Department of Colorectal&Hernial Minimally Invasive Surgery of Shengjing Hospital from Mar. 2015 to Jan. 2016, were collected to equivalently divided into continuous dissecting suture group and traditional interrupted suture group randomly. ② Twenty-seven patients with emergency open ostomy for colorectal surgery, who were treated in Department of Colorectal Tumor Surgery and Department of Colorectal&Hernial Minimally Invasive Surgery of Shengjing Hospital from Jan. 2009 to Jun. 2015, as well as 33 patients with elective open ostomy for colorectal surgery, who were treated in the same 2 Departments from Jul. 2015 to May. 2016, were collected to equivalently divided into silver ion dressing group and traditional dressing group. ③ Clinical data of 184 patients with elective open ostomy for colorectal surgery who were treated in Department of Colorectal Tumor Surgery and Department of Colorectal&Hernial Minimally Invasive Surgery of Shengjing Hospital from Jan. 2009 to May. 2016 were collected to analyze the influencing factors of SSI after elective open ostomy for colorectal surgery. Results ① There was no significant difference in the incidence of SSI between continuous dissecting suture group (3.3%, 1/30) and traditional interrupted suture group (16.7%, 5/30), P=0.085. ② The incidence of SSI in silver ion dressing group (6.7%, 2/30) was significantly lower than that of traditional dressing group (30.0%, 9/30), P=0.020. ③ There were 28 patients (15.2%) of the 184 elective patients and 11 patients (40.7%) of the 27 emergency patients suffered from SSI after open ostomy for colorectal surgery, and the incidence of SSI in elective surgery group was lower than that of emergency surgery group (P=0.001). ④ Results of logistic regression model showed that, patients with body mass index (BMI) <25 kg/m2 had lower risk of SSI than patients with BMI≥25 kg/m2(OR=0.383, P=0.023), patients received permanent colostomy had higher risk of SSI than patients received protective ileostomy (OR=4.370, P=0.004), patients underwent Mile’s surgery had higher risk of SSI than patients received distal anastomosis (OR=4.406, P=0.005). Conclusions The ostomy is a high risk factor for incisional SSI after elective open ostomy for colorectal surgery, especially for the obesity patients and patients who receive colostomy. The using of silver ion dressing play an important role in preventing the incisional SSI.

  • Anal Sphincteric Function Assessment of Intersphincteric Resection for Low Rectal Cancer by Vectorial Manometry

    Objective To assess the anal sphincteric function after intersphincteric resection for low rectal cancer by vectorial manometry. Methods Maximal anal pressure, vector volume, vector symmetric index and rectal anal inhibitory reflex were assessed in 16 patients underwent intersphincteric resection for low rectal cancer from 1999 to 2006. Thirty patients with low anterior resection for rectal cancer and another 30 healthy individuals were selected as control. Results The patients in intersphincteric resection group were subdivided into soiling group and defecation function good group. Maximal pressure, vector volume and vector symmetric index of the patients in soiling group and defecation function good group were significantly lower than those of the healthy and low anterior resection controls (P<0.001). The maximal systole pressure, systole vector volume and vector symmetric index in soiling group were significantly lower than those in function good group (P<0.001). The 25.0% patients in intersphincteric resection group had rectal anal inhibitory reflex, was significantly lower than that of the low anterior resection control group (93.3%, P<0.001). Conclusion The maximal pressure and vector volume are compromised in patients underwent intersphincteric resection . The vectorial manometry can be an objective comprehensive tool for the evaluation of anal sphincter function in patients with intersphincteric resection.

  • Expression of Obesity Hormone Leptin in Human Colorectal Cancer

    Objective To evaluate the relationship between leptin level in serum and clinicopathologic features of colorectal cancer. Methods ABC-ELLSA was used to detect the leptin level in 30 cases of colorectal cancer without dystrophy (cancer group) and 24 normal controls (control group). The expressions of K-ras, p53, adenomatous polyposis coli (APC) gene and delete in colorectal carcinoma gene (DCC) mRNA of the tumor were examined by RT-PCR, the levels of serum CEA and CA19-9, and other clinicopathologic features were also recorded. Results The leptin level in cancer group 〔(3.53±1.72) μg/L〕 was higher than that in control group 〔(2.27±1.01) μg/L〕, P<0.05, and the difference was independent on gender. There were no significant differences of leptin level in different tumor stages and different tumor location (Pgt;0.05). Leptin level of poorly differentiated tumor was obviously lower than that of well differentiated and moderately differentiated tumor (P<0.05). There were no associations between leptin level and the levels of CEA and CA19-9, likewise there were no associations between leptin level and the expressions of K-ras, p53, APC and DCC in tumor (Pgt;0.05). Conclusion The leptin level of colorectal cancer patient is higher than that of normal person, which is affected by the differentiation of tumor. But there are no significant correlations between the level of leptin in serum and TNM stage, tumor location, tumor markers of serum, K-ras, p53, APC or DCC in tumor.

  • Short-term clinical outcomes of double-modified Limberg flap transplantation in treatment of sacrococcygeal pilonidal sinus

    Objective To investigate short-term clinical outcomes of double-modified Limberg flap transplantation in treatment of sacrococcygeal pilonidal sinus. Methods One hundred patients with sacrococcygeal pilonidal sinus from October 2010 to May 2015 in this hospital were included, and subsequently were divided into double-modified Limberg flap transplantation group (double-modified flap group,n=30), classical Limberg flap transplantation (classical flap group,n=30), and interrupted suture after resection group (interrupted suture group,n=40). The duration of operation, intraoperative bleeding, hospital stay, duration of return to work, recurrence rate, and incision complications rate were compared among these three groups. Results ① The age, gender, body mass index, and preoperative complications had no significant differences among these three groups (P>0.05). ② The intraoperative bleeding and the hospital stay had no significant differences among these three groups (P>0.05). Compared with the interrupted suture group, the durations of operation were significantly longer (P<0.05), the durations of return to work were significantly shorter (P<0.05), the recurrence rates were significantly lower (P<0.05) in the double-modified flap group and the classical flap group. The above indicators had no significant differences between the double-modified flap group and the classical flap group (P>0.05). ③ The incision hematoma and the part disruption of incision had no significant differences among these three groups (P>0.05). Compared with the interrupted suture group, the rates of incision infection and incision complete disruption were significantly lower (P<0.05) in the double-modified flap group and in the classical flap group. The incision maceration of the classical flap group was significantly higher than that of the interrupted suture group (P<0.05) or the double-modified flap group (P<0.05). No skin flap necrosis occurred in the double-modified flap group and the classical flap group. Conclusions Double-modified Limberg flap transplantation and classical Limberg flap transplantation have less complications and lower recurrence rate than interrupted suture after resection. Compare with classical Limberg flap transplantation, double-modified Limberg flap transplantation has a lower incision maceration rate. Because of limitation of sample size in this study, long-term clinical efficacy of double-modified Limberg flap transplantation needs to be confirmed by multicenter randomized controlled trials.
