Objective To explore the feasibility of single?incision laparoscopic sigmoid colon vaginoplasty in women with congenital absence of va?gina. Methods Clinical data of thirty?two patients with congenital absence of vagina admitted in Shengjing Hospital of China Medical University be?tween January 2008 and June 2014 was retrospectively analyzed. Nineteen patients underwent laparoscopic assisted sigmoid colon vaginoplasty,and thirteen paitiens underwent single?incision laparoscopic sigmoid colon vaginoplasty. The operation time,intraoperative blood loss,evacuation time and follow up were compared between the two groups. Results In the group of single?incision laparoscopic sigmoid colon vaginoplasty,the opera?tion time was shorter and intraoperative blood loss was less. There was no difference between two groups in evacuation time. There was no infection or leakage of anastomotic stoma of sigmoid colon,and no postoperative stenosis of the neovagina and its length was satisfied. Patients were satisfied with the quality of sexual life after the surgery. Patients underwent single?incision laparoscopic sigmoid colon vaginoplasty were all satisfied with the ap?pearance of abdomen. Conclusion The single?incision laparoscopic sigmoid colon vaginoplasty can simplify the procedure of intestinal anastomo?sis,shorten the operation time,and reduce the intraoperative blood loss. Consequently,the single?incision laparoscopic sigmoid colon vaginoplasty is effective and safe.

Objective To investigate the safety and feasibility of uterine arterial embolization (UAE) combined with hystersocpic excisionl of exogenous cesarean scar pregnancy (CSP). Methods Totally 67 patients with exogenous CSP treated with selective UAE combined with hysterscopic surgery in Shengjing Hospital of China Medical University were analyzed retrospectively; 35 patients in Group A (thickness of the cesarean scar>3 mm), while 32 patients in Group B (thickness of the cesarean scar≤3 mm). The following clinical parameters including operative time, intraoperative blood loss, quantity of postoperative uterine drainage, postoperative hospital days, the time for the mass absorption and the return ofβ-hCG to normal were compared. Results All hysterscopic procedures were successfully completed in Group A, and only one case underwent a second hysteroscopic excision due to the 1-month postoperative ultrasound examination indicating a mass located in the cesarean scar and a slow decline of β-hCG. Three cases of Group B were transformed to laparoscopic or laparotomy operation and 7 cases underwent a second surgery. The volume of introperative blood loss was (97±41) ml in Group A and (161±92) ml in Group B, the difference was statistically significant (P<0.01). But the operative time, quantity of postoperative uterine drainage, postoperative hospital days, the time for the retrun ofβ-hCG to normal and the mass absorption in Group A were (36±9) minutes, (38±13) ml, (3.5±0.5) days, (26±5) days, (82±17) days, in Group B were (37± 9) minutes, (42 ± 16) ml, (4.0 ± 0.7) days, (28 ± 8) days, (88 ± 15) days, respectively, the differences were not statistically significant (all P>0.05). Conclusions For exogenous CSP, when the thickness of cesarean scar is ≤3 mm, whether or not undertaking UAE, it should be seen as contraindication of hysterscopic surgery. UAE combined with hysterscopic surgery for the treatment of exogeous CSP with the cesarean scar thickness>3 mm is safe and feasible according to patients condition and should be performed by experienced hysteroscopist.

BACKGROUND:In palatorrhaphy, iodoform gauzes are often used to fill the bilateral relaxation incisions and cover the wound. However, there are a series of postoperative complications, such as fever, loss of appetite, foreign body sensation, secondary bleeding. In order to avoid or reduce the complications after palatorrhaphy, the use of gelatin sponge to fill bilateral relaxation incisions has achieved good clinical results.OBJECTIVE:To compare the clinical effects of different treatments on wound healing after palatorrhaphy.METHODS:110 child patients with cleft palate were selected and assigned into two groups according to admission time. Fifty-four patients who admitted from January 2013 to December 2015 (experimental group) were obturated with gelatin sponge, while the other 56 patients who admitted from January 2008 to December 2012 (control group) were obturated with idoform gauze. The postoperative results of patients were assessed in various aspects, including psychological impact, diet, body temperature, bleeding, and wound healing. The incision scar width was measured at 4 weeks postoperatively.@RESULTS AND CONCLUSION: (1) Patients in the experimental group experienced shorter recovery time than those in the control group (P < 0.05). (2) Patients in the experimental group had substantialy lower incidence of fever postoperatively, and shorter duration of fever than those in the control group (P < 0.05). (3) In comparison to the control group, the experimental group showed less postoperative complications such as bleeding and vomiting (P < 0.05). (4) The incision scar width in the experimental group was significantly narrower than that in the control group (P < 0.05) after 4 weeks. These experimental findings demonstrate the superior effect of gelatin sponge over iodoform gauze and its value in clinical application with better healing, less bleeding, shorter recovery time and no impact on eating.
