“…After esophagojejunostomy, it's easier for π-shaped method to close the common incision by a linear stapler, and the operative time is reduced. In this study, more cases in π-shaped group were operated on 3D laparoscopy, and several studies reported that 3D laparoscopy can harvest more lymph nodes than 2D laparoscopy [38][39][40][41][42]. That might be the reason for the difference in number of dissected lymph nodes.…”

Objective Laparoscopic-assisted total gastrectomy (LATG) is the most common methods of gastrectomy for gastric cancer (GC). However, totally laparoscopic total gastrectomy (TLTG) is uncommon because reconstruction is difficult, especially for the intracorporeal esophagojejunostomy. In this study, we compared short-term oncologic outcomes in TLTG group with linear anastomosis and LATG group. Methods The retrospective cross-sectional study was conducted. The clinic-pathological data of 108 patients underwent TLTG and 153 patients underwent LATG who were admitted to the First Affiliated Hospital of Nanjing Medical University between May 2016 and October 2019 were collected. The clinicopathological characteristics and surgical outcomes before and after propensity score matching (PSM) were compared between the two groups. Furthermore, a systematic review and meta-analysis were conducted. Results Besides the estimated blood loss(P < 0.001) and the length of incision(P < 0.001) in TLTG group was less than those in LATG group, no other differences were found between the two groups in operative time (P = 0.993), the number of harvested lymph nodes (P = 0.181), the time of first flatus(P = 0.076), start of liquid diet (P = 0.240), start of soft diet (P = 0.147), the time of removing drainage (P = 0.725), postoperative hospital stay (P = 0.688)and postoperative morbidity (P = 1.000) after PSM. The meta-analysis also demonstrated no significant differences in above surgical outcomes among the groups, although the number of harvested lymph nodes was higher and estimated blood loss was lower in the TLTG group than that in the LATG group. Conclusions TLTG for GC is feasible and safe. However, the further validation of high-quality randomized controlled trial is still needed.

“…We attributed those advantages to the magnification effect, 3D sense, and spatial depth of the surgical field. Because 3D laparoscopic surgery made it easier to obtain the correct anatomical landmark and dissect important tissues accurately such as blood vessels, nerves and perigastric lymph nodes[ 24 , 25 ]. 3DLAGC group had less intestinal traction and flipping, damage to surrounding tissues during adhesiolysis, trauma and inflammatory response.…”

BACKGROUND Three-dimensional (3D) laparoscopic technique has gradually been applied to the treatment of carcinoma in the remnant stomach (CRS), but its clinical efficacy remains controversial. AIM To compare the short-term and long-term results of 3D laparoscopic-assisted gastrectomy (3DLAG) with open gastrectomy (OG) for CRS. METHODS The clinical data of patients diagnosed with CRS and admitted to the First Medical Center of Chinese PLA General Hospital from January 2016 to January 2021 were retrospectively collected. A total of 84 patients who met the inclusion and exclusion criteria were enrolled. All their clinical data were collected and a database was established. All patients were treated with 3DLAG or OG by experienced surgeons and were divided into two groups based on the different surgical methods mentioned above. By using outpatient and telephone follow-up, we were able to determine postoperative survival and tumor status. The postoperative short-term efficacy and 1-year and 3-year overall survival (OS) rates were compared between the two groups. RESULTS Among 84 patients with CRS, 48 were treated with OG and 36 with 3DLAG. All patients successfully completed surgery. There was no significant difference between the two groups in terms of age, gender, body mass index, ASA score, initial disease state (benign or malignant), primary surgical anastomosis method, interval time of carcinogenesis, and tumorigenesis site. Patients in the 3DLAG group experienced less intraoperative blood loss (188.33 ± 191.35 mL vs 305.83 ± 303.66 mL; P = 0.045) and smaller incision (10.86 ± 3.18 cm vs 20.06 ± 5.17 cm; P < 0.001) than those in the OG group. 3DLAGC was a more minimally invasive method. 3DLAGC retrieved significantly more lymph nodes than OG (14.0 ± 7.17 vs 10.73 ± 6.82; P = 0.036), whereas the number of positive lymph nodes did not differ between the two groups (1.56 ± 2.84 vs 2.35 ± 5.28; P = 0.413). The complication rate (8.3% vs 20.8%; P = 0.207) and intensive care unit admission rate (5.6% vs 14.5%; P = 0.372) were equivalent between the two groups. In terms of postoperative recovery, the 3DLAGC group had a lower visual analog score, shorter indwelling time of gastric and drainage tubes, shorter time of early off-bed motivation, shorter time of postoperative initial flatus and initial soft diet intake, shorter postoperative hospital stay and total hospital stay, and there were significant differences, showing better short-term efficacy. The 1-year and 3-year OS rates of OG group were 83.2% [95% confidence interval (CI): 72.4%-95.6%] and 73.3% (95%CI: 60.0%-89.5%) respectively. The 1-year...
