ABSTRACT
Objective: To explore the clinical safety and feasibility of overlapped delta-shaped anastomosis (ODA) in totally laparoscopic right hemicolectomy (TLRHC). Methods: From May 2017 to October 2019, of the 219 patients who underwent TLRHC at the Cancer Hospital, Chinese Academy of Medical Science and Peking Union Medical College, 104 cases underwent ODA (ODA group) and 115 cases underwent conventional extracorporeal anastomosis (control group) were compared the surgical outcomes, postoperative recovery, pathological outcomes and perioperative complications. Results: The length of the skin incision in the ODA group was significantly shorter than that in the control group [(5.6±0.9) cm vs. (7.1±1.7) cm, P<0.05], and the time to first flatus and first defecation after surgery in the ODA group was significantly earlier than that in the control group [(1.7±0.7) days vs. (2.0±0.7) days; (3.2±0.6) days vs. (3.3±0.7) days, P<0.05]. While the anastomosis time, operation time, intraoperative blood loss, the time of first ground activities, the number of bowel movements within 12 days after surgery, postoperative hospital stay, tumor size, the distal and proximal margins, the number of lymph node harvested and postoperative TNM stage in the ODA group did not differ from that of the control group (P>0.05). The postoperative complication rates of patients in the ODA group and the control group were 3.8% (4/104) and 4.3% (5/115), respectively, and the difference was not significant (P>0.05). Conclusion: The application of ODA technology in TLRHC can significantly shorten thelength of skin incisionand the recovery time of bowel function, and can obtain satisfactory short-term efficacy.

Objective: At present, though the laparoscopic delta-shaped anastomosis and overlapping delta-shaped anastomosis have been gradually applied to complete laparoscopic radical resection of left hemicolon cancer, the comparative evaluation of their efficacy has not been mentioned in the published literatures. This study aims to explore the safety, feasibility and short-term efficacy of overlapping delta-shaped anastomosis (ODA) in totally laparoscopic left hemicolectomy. Methods: A retrospective cohort study was performed. The clinical and pathological data of patients who underwent totally laparoscopic left hemicolectomy at Department of Colorectal Surgery, Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from May 2017 to October 2020 were retrospectively analyzed. The case inclusion criteria were as follows: (1) age of 18-75 years; (2) body mass index (BMI) of 18.5-30 kg/m(2); (3) descending colonic and proximal sigmoid colonic adenocarcinoma was confirmed by preoperative colonoscopy and pathology. The exclusion criteria: (1) multiple primary colorectal cancers; (2) uncontrolled or poorly controlled diabetes mellitus, immune system diseases, or hematological diseases; (3) severe intestinal obstruction; (4) left transverse colonic or splenic flexure colonic adenocarcinoma; (5) distant metastasis of liver, lung and other viscera determined by enhanced computed tomography in the chest, abdomen and pelvis. According to the above criteria, a total of 115 patients with left hemicolon cancer were enrolled. All the patients underwent totally laparoscopic left hemicolectomy. Patients who underwent laparoscopic traditional delta-shaped anastomosis were selected as the control group. Patients who underwent laparoscopic ODA were selected as the ODA group. Effects of these two laparoscopic reconstruction methods on postoperative recovery and perioperative complications were analyzed and compared. Results: A total of 60 patients were enrolled in the ODA group, including 32 males and 28 females, with mean age of (57.3±10.4) years and body mass index (BMI) of (25.0±3.1) kg/m(2). While mean 55 patients were enrolled in the control group, including 31 males and 24 females, with mean age of (56.7±9.9) years and BMI of (24.4±2.9) kg/m(2). There was no statistically significant differences between the two groups in gender, age, BMI, American Society of Anesthesiologist (ASA) classification, TNM staging, preoperative abdominal surgery history, neoadjuvant chemotherapy and nutritional status (levels of hemoglobin, lymphocyte count, prealbumin, and albumin) (all P>0.05). All the patients in both groups received R0 resection without conversion to open laparotomy or conversion to extra-abdominal anastomosis. The digestive tract reconstruction time of the ODA group was significantly shorter than that of the control group [(15.1±1.7) minutes vs. (15.9±2.4) minutes, t=-2.053, P=0.042]. There were no statistically significant differences in the total operation time, intraoperative blood loss, length of skin incision, tumor size, proximal and distal margins, harvested lymph nodes, postoperative first ambulatory time, and postoperative hospital stay (all P>0.05). However, the time to the first flatus and the first defecation in the ODA group was significantly shorter as compared to control group [(1.5±0.5) days vs. (1.7±0.5) days, t=-2.028, P=0.045; (3.1±0.6) days vs. (3.4±0.7) days, t=-2.095, P=0.039], indicating faster intestinal function recovery in patients with ODA. The morbidity of postoperative complication was 6.7% (4/60) in the ODA group and 7.3% (4/55) in the control group and no significant difference was found (χ(2)=0.016, P=0.898). Two cases of incision infection, 1 case of lung infection, and 1 case of intra-abdominal infection occurred in the ODA group, while 3 cases of lung infection and 1 case of intra-abdominal infection occurred in the control group. All these complications were resolved after conservative treatment, and no secondary operation was performed due to complications. Conclusion: Compared with the traditional delta-shaped anastomosis, ODA is associated with a faster recovery of postoperative intestinal function without increasing the morbidity of postoperative complications, and has the satisfactory short-term efficacy.

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.
