Objective To explore feasibility and efficacy of laparoscopic microsurgery by transanal glove port for excision of rectal tumor. Methods Seventeen patients with rectal tumor underwent laparoscopic microsurgery by transanal glove port for local excision of rectal tumor were chosen from March 2015 to March 2016. This device was constructed by using a incision protective sleeve and standard surgical glove. The laparoscopy was used as lighting equipment. The ultrasonic scalpel, operation forceps and lens were separately inserted into the fixed sheath card from the 3 finger gloves. Results The operations of 17 cases were completed successfully. The operative time was 35–90 min with an average 54 min. The closed glove access time was 11 to 26 min with an average 18 min. The diameter of tumor was 1.4–3.5 cm with an average 2.4 cm. The results of postoperative pathology included 8 cases of villos adenemas, 3 cases of high-grade intraepithelial neoplasia, 1 case of low-grade intraepithelial neoplasia, 3 cases of carcinoid , and 2 cases of adenocarcinoma. All resection margins were negative. No infection, intestinal fistula, bleeding, and other complications were found. The hospital stay was 4–9 d with an average of 5 d. No recurrence was found during a follow-up of 1–6 months. Conclusions The preliminary results of limited cases in this study show that laparoscopic microsurgery by transanal glove port for excision of rectal tumor is easy, safe, and effective. It also provides a new choice for individualized comprhensive treatment of rectal tumor.
Objective To explore the advantage of transection the cervical muscles at sternal end and flip fixed in therapeutic bilateral huge thyroid surgery. Methods The transection of the cervical muscles at sternal end and flip fixed in 53 cases was observation group， 44 cases of the neck white line incision thyroid surgery completed for the control group. The completion of the surgery by the same group of physicians. The operative time， operation field of exposing effect， amount of bleeding in operation， postoperative complications， and postoperative drainage volume were compared between two groups. Results There was no statistically differences of sex， age， disease composition， and tumor size between two groups （P＞0.05）. Operative time， amount of bleeding， and postoperative drainage volume in observation group were shorter （less） than that in control group （P＜0.01）. The postoperative complication rate in observation group was lower than that in control group（P=0.04）. Surgical field exposure in observation group was better than that in control group （P＜0.01）. Conclusions The huge bilateral thyroid surgery with the sternal end approach is feasible and simple. The operation field exposure is better than the white line neck incision， complications after operation is less. It is worthy of clinical application.
Objective To explore clinicopathologic features and prognostic factors of different pathological types of advanced gastric cancer. Methods The clinicopathologic data of 98 patients with advanced gastric cancer who underwent radical gastrectomy in Suqian People’s Hospital, Nanjing Drum Tower Hospital Group, Affiliated to Nanjing University Medical School in 2011 were analyzed retrospectively. There were 53 cases of gastric adenocar-cinoma, 30 cases of mucinous adenocarcinoma, and 15 cases of signet ring cell carcinoma among them. The differences of clinicopathologic characteristics and prognosis were compared among different pathological types of advanced gastric cancer. Results ① There were no significant differences in terms of the gender, age, nerve invasion, and degree of differentiation among the three groups (P>0.05), there were significant differences in terms of the tumor diameter, tumor location, radical surgery type, regional lymph node metastasis, lymphatic cancer embolus, depth of invasion, and pTNM stage among the three groups (P<0.05). ② The results of the univariate analysis showed that the prognosis of gastric adenocarcinoma was associated with the tumor diameter, tumor location, radical surgery type, regional lymph node metastasis, depth of invasion, or pTNM stage (P<0.05); the prognosis of mucinous adenocarcinoma was associated with the radical surgery type, regional lymph node metastasis, or pTNM stage (P<0.05); the prognosis of signet ring cell carcinoma was associated with the regional lymph node metastasis, depth of invasion, and pTNM stage (P<0.05). ③ The results of the Cox multivariate analysis showed that the tumor location (P=0.016), regional lymph node metastasis (P=0.042), invasion depth (P=0.021), and pTNM stage (P=0.009) were the independent risk factors of prognosis for the gastric adenocarcinoma; the regional lymph node metastasis was the independent risk factor of prognosis for gastric mucinous adenocarcinoma (P=0.000); the tumor invasion depth (P=0.032) and regional lymph node metastasis (P=0.002) were the independent risk factors of prognosis for signet ring cell carcinoma. ④ The follow-up time was 60 months. The median follow-up time was 32 months in the gastric adenocarcinoma, 43 months in the mucinous adenocarcinoma, 23 months in the signet ring cell carcinoma, the 5-year accumulated survival rate was 30.2%, 23.3%, and 26.7% respectively. The comparison of survival curves of these three different pathological types of gastric cancer had no significant difference (P=0.131). Conclusion Clinical and pathological features of patients with different pathological types of advance gastric cancer present some differences, and prognostic factors are also different, but regional lymph node metastasis is a common prognostic factor for different pathological types of advanced gastric cancer.
