Objective: The aim of this study was to explore the clinical safety, feasibility and short-term effect of overlapped delta-shaped anastomosis in total laparoscopic transverse colectomy. Methods: The records, which were based on China National Cancer Center, of 20 and 31 patients who underwent total laparoscopic transverse colectomy with overlapped delta-shaped anastomosis and laparoscopic-assisted transverse colectomy with conventional extracorporeal anastomosis, from March 2017 to May 2018 were reviewed retrospectively. Data regarding surgical outcomes, postoperative recovery, pathological outcomes and perioperative complications were collected and compared. Results: There was no difference between the two groups in overall operation time, anastomosis time and intraoperative blood loss (P>0.05), however, the length of incision was significantly shorter in overlapped delta-shaped group [(4.7±0.6) cm vs. (5.5±1.0) cm, P=0.002]. The time to ground activities, first flatus and postoperative hospitalization did not differ between the two groups (P>0.05). The postoperative visual analogue scale was lower in the overlapped delta-shaped group than the control group on postoperative day 1 (3.7±0.7 vs. 4.2±0.9, P=0.015) and postoperative day 3 (2.7±0.5 vs. 3.2±0.9, P=0.040). The perioperative complication rates were 10.0% and 12.9% in the overlapped delta-shaped group and the control group, respectively, and the difference was not significant (P=0.753). Conclusion Compared to conventional extracorporeal anastomosis, total laparoscopic transverse colectomy with overlapped delta-shaped anastomosis was a safe and feasible procedure with satisfactory short-term effect, shorter incision and less postoperative pain.

Objective: To explore the clinical safety and feasibility of enterostomy using running suture of dermis and seromuscular layer in laparoscopic-assisted radical resection for rectal carcinoma. Methods: From May 1, 2017 to May 1, 2018, 46 patients who underwent laparoscopic-assisted radical resection for rectal carcinoma with enterostomy using running suture of dermis and seromuscular layer in Cancer Hospital, Chinese Academy of Medical Sciences were retrospectively enrolled in this study. Data regarding clinicopathologic characteristics, operation and postoperative outcomes, stoma-related complications and functions of stoma were collected and analyzed. Results: All of the 46 patients successfully underwent this operation. Among them, 30 patients underwent laparoscopic-assisted abdominoperineal resection for rectal cancer with sigmoidostomy and 16 patients underwent laparoscopic-assisted low anterior resection for rectal cancer with loop ileostomy. The mean operation time was 115.3 minutes and intraoperative blood loss was 86.1 ml. The mean time for enterostomy was 14.1 minutes. The average time to flatus, time to fluid diet intake and length of hospital stay were 1.8 days, 2.9 days and 6.5 days, respectively. During the follow-up period, three patients suffered from stomal edema, two patients suffered from parastomal hernia, and two patients suffered from skin inflammation surrounding stoma. None of re-operation related stoma and severe mobility such as stomal stenosis, stomal necrosis, stomal prolapse, stomal retraction and stomal mucocutaneous separation occurred. Thirty-five patients recovered with satisfactory stomal function, two with middle function and one with poor function. Conclusion Enterostomy using running suture of dermis and seromuscular layer in laparoscopic-assisted radical resection for rectal carcinoma is a safe and feasible procedure with a satisfactory short-term effect.

Objective: This study aims to explore the clinical value of fusion indocyanine green fluorescence imaging (FIGFI) in total laparoscopic radical resection for right colon cancer. Methods: From October, 2018 to December, 2018, 15 patients who underwent total laparoscopic radical resection for right colon cancer using FIGFI in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College were retrospectively enrolled in this study. Data regarding surgical outcomes, postoperative recovery, pathological outcomes and complications were collected and analyzed. Results: All patients successfully underwent total laparoscopic radical resection for right colon cancer using FIGFI. 1 patients (6.7%) received extended resection of bowel due to poor blood supply after mesentery excision. The average operation time was 133.7 minutes and intraoperative blood loss was 26.7 ml. The average time to ground activities, fluid diet intake, first flatus and postoperative hospitalization were 19.1 h, 11.7 h, 32.5 h and 5.0 d, respectively. The average length of tumor was 4.5 cm. The average proximal and distal resection margins were 14.9 cm and 12.1 cm, respectively. The average number of lymph nodes retrieved was 29.3 per patient. Only one patient suffered from incisional fat liquefaction after surgery and was managed effectively by regular dressing change. No severe complications such as indocyanine green allergy, anastomotic stenosis, anastomotic leakage, abdominal bleeding, bowel obstruction, pulmonary infection, and abdominal infection occurred in any patients. Conclusions FIGFI is helpful to judge the blood supply of intestinal segments and anastomotic stoma in total laparoscopic radical resection for right colon cancer quickly. It is a safe and feasible technique with satisfactory short-term effect.

OBJECTIVE: To explore the safety and feasibility of the overlapped delta-shaped anastomosis (ODA) technique for cases undergoing totally laparoscopic right hemicolectomy (TLRH). METHODS: Clinical data of patients who underwent TLRH using the ODA technique or the modified delta-shaped anastomosis (MDA) technique at Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from January 2016 to December 2017 were retrospectively analyzed. INCLUSION CRITERIA: (1)diagnosed with adenocarcinoma by enteroscopy before operation; (2)cancer locating at ascending colon or transverse colon hepatic region and receiving TLRH surgery. EXCLUSION CRITERIA: (1) double or multiple primary colorectal cancers;(2)with complete or incomplete intestinal obstruction; (3) combined multiple organs resection; and (4) with unresectable distant metastases. The ileum and the transverse colon were sutured in an overlapped fashion about 8 cm away from the end of the ileum firstly, and then two small openings locating at the end of ileum and the corresponding site of the transverse colon were created in the ODA procedure, and the two small openings both locating at the end of ileum and the transverse colon were created in the MDA procedure. Statistical analysis was performed using SPSS 24.0 software and the general information, surgical and pathological results, and complications between two groups were compared. RESULTS: A total of 108 patients were enrolled in this study, including 52 patients in the ODA group and 56 patients in the MDA group. In the ODA group, 28 patients were male and 24 were female with age of (53.3±10.0) years and body mass index (BMI) of (24.2±2.7) kg/m. In the MDA group, 27 patients were male and 29 were female with a mean age of (54.5±9.4) years and body mass index of (23.8±2.4) kg/m. There were no significant differences between the two groups in terms of age, gender, BMI, history of previous abdominal surgery, scoring of American Society of Anesthesiologists, tumor location, pathological TNM stage, and number of dissected lymph node (all P>0.05). All the patients underwent R0 resection without conversion to open surgery or to extraperitoneal anastomosis. The time of anastomosis in the ODA group was shorter than that in the MDA group[(15.7±2.3) minutes vs.(18.6±3.6) minutes], and the difference was statistically significant (t=-5.017, P<0.001). There were no significant differences between two groups in total operative time[(160.7±17.8) minutes vs.(163.2±17.6) minutes], intraoperative blood loss [(77.7±28.3) ml vs.(75.9±31.8) ml], length of incision [(5.8±1.1) cm vs. (5.9±1.1) cm], time to first flatus [(1.8±0.2) days vs. (1.9±0.3) days], time to first oral intake [(1.9±0.5) days vs. (1.9±0.4) days], postoperative complications [3.8%(2/52) vs. 5.4%(3/56)], and postoperative hospital stay [(6.7±0.9) days vs. (6.8±0.8) days]. CONCLUSIONS The ODA technique is less time-consuming without increasing postoperative complications compared to the MDA technique, which is a safe and feasible technique in TLRH worth further promotion.
