BACKGROUND:Abdominal incision healing is not only related with the patient’s own situation, but also closely related with the surgeon's suture technique, suture method, choice of stitches. ＜br> OBJECTIVE:To compare the absorbable sutures and silk sutures for abdominal incision. ＜br> METHODS:Total y 153 colorectal cancer patients, including 91 males and 62 females, aged 30-82 years, were randomly divided into observation group (n=78) and control group (n=75). An abdominal midline incision was made in al patients receiving radical surgery of colorectal cancer. The Vicryl suture and silk suture were respectively used in the observation and control groups for abdominal incision closure. Suturing time, length of hospital stay, incision infection, disruption of wound, fat liquefaction of wound and rejection were compared between two groups. ＜br> RESULTS AND CONCLUSION:The suturing time and length of hospital stay were less in the observation group than the control group (P＜0.05). In the observation group, there were three cases of incision infection, but no incision dehiscence and rejection occurred;in the control group, there were 10 cases of incision infection, 4 cases of incision dehiscence, and 5 cases of rejection. A significant difference was found in the incision infection, dehiscence and rejection between the two groups (P＜0.05). Hospitalization expenses and fat liquefaction of incision had no difference between the two groups. these findings indicate that the Vicryl plus as an absorbable suture is simple, effective and safe that can promote wound healing and reduce complications.

Objective To explore the pathologic features and distribution characteristics of upper gastrointestinal submucosal tumors (SMT).Methods From January 2013 to December 2017,at Department of Gastroenterology of Taizhou Hospital Affiliated to Wenzhou Medical University,clinical data of 1 182 hospitalized patients with 1 237 upper gastrointestinal SMT who underwent endoscopic therapy and diagnosed by pathology and immunohistochemistry was retrospectively analyzed including the pathological types,tumor of locations,endoscopic findings,layer of origin and tumor size.Results There were 473 esophageal SMT,including 387(81.8％) leiomyomas,located in the mucosal muscularis or muscularis propria;and 59(12.5％)cysts located in the submucosa or mucosal muscularis.There were 138(29.2％) lesions,159(33.6％) lesions and 176(37.2％) lesions in the upper,middle and lower esophagus respectively,and the most common type was leiomyoma.A total of 723 tumors were gastric SMT,among them 284 (39.3％) lesions were gastrointestinal stromal tumors (GIST) and 273(37.8％) lesions were leiomyomas,and all located in the muscularis propria.A total of 69(9.5％) lesions located at cardia,the common types were leiomyoma (55 lesions,79.7％) and GIST (nine lesions,13.0％).A total of 239 (33.1％) lesions located at gastric fundus,the common types were GIST (152 lesions,63.6％) and leiomyoma (79 lesions,33.1％).A total of 280 (38.7％) lesions located at gastric body,the common types were leiomyoma (138 lesions,49.3％) and GIST (111 lesions,39.6％).A total of 127 (17.6％) lesions located at gastric antrum,the common types were heterotopic pancrease (71 lesions,55.9％) and lipoma (26 lesions,20.5％),and all were located in the submucosa,some involved the muscularis propria.There were six (0.8％) lesions at gastric angle,and two (0.3％) at gastrointestinal anastomosis.Forty-one lesions were duodenal SMT,among them 23(56.1％) located at duodenal bulb,the common types were cyst (10 lesions,43.5％),lipoma (five lesions,21.7％) and heterotopic pancrease (five lesions,21.7％).A total of 18(43.9％) lesions located at descending duodenum,the common types were lipoma (nine lesions,50.0％) and cyst (five lesions,27.8％),and all lesions located in the submucosa.Conclusions The most common type of SMT in the esophagus and cardia is leiomyoma,however the SMT in gastric fundus and body are mostly leiomyomas and GIST,while in gastric antrum,most SMT are heterotopic pancreases and lipomas.In duodenal bulb and descending duodenum,the common types of SMT are cyst and lipoma.

Objective:To explore the diagnosis, staging, and treatment of fibro-adipose vascular anomaly(FAVA).Methods:The data of the patients with FAVA admitted to Xi’an International Medical Center Hospital between October 2019 and February 2023 were retrospectively reviewed. Ultrasound and magnetic resonance imaging (MRI) were routinely performed. X-ray and CT were performed for patients with unequal length of lower limbs, lesions involving joints, and obvious joint deformities. The treatment plan was made according to the stage: stage Ⅰ (pain stage), open or laparoscopi radical resection of the lesion was performed; stage Ⅱ (contracture stage), radical surgery was performed to remove the lesion, sometimes combined with Achilles tendon lengthening or tenolysis, and rehabilitation training was performed 2 weeks after surgery; stage Ⅲ(deformity stage), comprehensive treatment based on surgical resection was adopted, combined with joint capsule release, Achilles tendon lengthening or dissection, tendon transfer and oral sirolimus (each time 0.08 mg/m 2, twice daily ) before and after the operation. For patients with lesions involving multiple anatomical regions, staged surgery was performed, and in principle, only one anatomical region was operated per time. Patients were followed up for pain, joint activity and recurrence. Results:A total of 42 patients were admitted, including 18 males and 24 females. The onset age was (7.3±5.0) years, but the average age of diagnosis was (12.5±6.0) years. The lower limbs were involved in 38 cases, the upper limbs in 4 cases. There were 17 cases of stage Ⅰ, 17 cases of stage Ⅱ and 8 cases of stage Ⅲ. Only 4 cases had no misdiagnosis experience, and the misdiagnosis rate was 90.5%(38/42). Persistent pain, muscle contractures and joint deformities were the main clinical symptoms of the disease. MRI showed heterogeneous high and low signal intensity on T1-weighted images, and the high signal intensity was the same as that of subcutaneous adipose tissue. T2 fat-suppressed sequences showed stronger heterogeneous hyperintensity. The follow-up time was (14.6±10.8) months. Patients who took sirolimus orally before or after surgery experienced significant relief of pain symptoms. Of the 42 patients, the symptoms of 31 patients were completely relieved after the operation, and 11 patients still had residual pain or joint movement disorder or even deformity after the operation. Sixteen of 17 stage Ⅰ patients were cured, the lesion was further expanded and the pain recurred in 1 case after the operation. Of the 17 stage Ⅱ patients, 15 were cured, and 2 had mild limitation of ankle movement after the operation. Eight stage Ⅲ patients had varying degrees of pain or joint movement disorder after surgery, postoperative oral sirolimus significantly relieved symptoms. All 10 patients with stage Ⅰ and Ⅱ who underwent endoscopic resection were cured.Conclusion:FAVA usually occurred in school-age and adolescent children. Pain, muscle contracture and joint deformity were the characteristic clinical features. Combined with MRI features, the diagnosis can be confirmed. FAVA staging system could guide treatment and predict prognosis. For stage Ⅰ and Ⅱ patients, surgery should be performed as soon as possible and the prognosis was good. For stage Ⅲ patients, surgery-based comprehensive treatment could improve symptoms, but it was difficult to cure them radically. Oral sirolimus was also required after surgery.
