RESUMO
Objective:To investigate the clinical effects of totally robotic digestive tract reconstruction and modified right iliac auxiliary Trocar hole for specimen extraction in radical proctectomy.Methods:The retrospective and descriptive study was conducted. The clinical data of 139 patients with rectal cancer who were admitted to the Chongqing University Three Gorges Hospital from June 2019 to January 2022 were collected. There were 81 males and 58 females, aged (64±15)years. All patients underwent radical proctectomy with totally robotic alimentary tract reconstruction and modified right iliac auxiliary Trocar hole for specimen extraction. Observation indicators: (1) surgical and postoperative situations; (2) follow-up. Measurement data with normal distribution were represented as Mean± SD, and count data were represented as absolute numbers. Results:(1) Surgical and postoperative situations. All the 139 patients completed radical proctectomy with totally robotic alimentary tract reconstruction and modified right iliac auxiliary Trocar hole for specimen extraction successfully, without conversion to laparotomy, unplanned return to surgery or death. The length of surgical incision was (4.5±1.1)cm, operation time was (157±63)minutes, volume of intraoperative blood loss was (65±22)mL, time to postoperative first out-of-bed activities was (2.36±0.29)days, time to first flatus was (2.27±1.13)days, and time to first liquid diet was (2.90±1.12)days. The pain scores at postoperative day 1, 2, 4 were 2.34±1.07, 1.26±0.36, 0.10±0.06. The hospitalization time was (8.92±2.15)days. Results of postoperative pathological examination: the number of lymph nodes dissected was 18.1±2.3, the distal resection margin distance of tumor was (2.6±0.5)cm, and the proximal resection margin distance of tumor was (13.1±2.6)cm. The mesorectum of all specimens was intact, and the circumferential resection margin was negative. Of 139 patients, 1 case of incision fat liquefaction, 1 case of anastomotic leakage, 1 case of anastomotic bleeding, 1 case of intestinal obstruction after operation were discharged after treatment. There was no complication such as abdominal infection or hemorrhage, chylous leakage, abdominal infection. (2) Follow-up. All the 139 patients were followed up for 1 year after operation. No chronic infection of abdominal incision, incisional hernia, incisional tumor implantation, chronic incision pain, sexual dysfunction, dysuria or fecal incontinence were found during the 1-year follow-up.Conclusion:Totally robotic alimentary tract reconstruction and modified right iliac auxiliary Trocar hole for specimen extraction is safe and feasible in radical proctectomy, which has clinical application value.
RESUMO
Objective To investigate the breast cancer neoadjuvant chemotherapy for clinical applica-tion.Methods Given suitable breast cancer patients anthracycline-based combination chemotherapy, 2 ～ 4 cy-cle after the surgery were observed to assess their clinical efficacy and conform to conditions and are compatible with the same period did not receive neoadjuvant chemotherapy for a comparative analysis of cases.Results Ac-ceptance of neoadjuvant chemotherapy group of cases the total effective rate was 89.47%, 1-year and 3-year over-all survival rate significantly improved, 17 cases due to neoadjuvant chemotherapy benefit received axillary lymph node dissection to narrow the scope of the modified radical mastectomy for breast cancer, five cases of implemen-tation of the breast retain on the radical operation of breast cancer.Conclusions Neoadjuvant chemotherapy can effectively reduce the clinical stage of breast cancer, some patients benefit from breast-implementation, such as radical mastectomy or surgery to narrow the scope, postoperative survival and prognosis of breast cancer is there-fore improved.
