Postoperative morbidity and quality of life between totally laparoscopic total gastrectomy and laparoscopy-assisted total gastrectomy: a propensity-score matched analysis

Background This study aimed to evaluate the surgical outcome and quality of life (QoL) of totally laparoscopic total gastrectomy (TLTG) compared with laparoscopy-assisted total gastrectomy (LATG) in patients with clinical stage I gastric cancer. Methods From 2012 to 2018, EGC patients who underwent TLTG (n = 223), including the first case with intracorporeal hemi-double stapling, were matched to those who underwent LATG (n = 114) with extracorporeal circular stapling, using 2:1 propensity score matching (PSM). Prospectively collected morbidity was compared between the TLTG and LATG groups in conjunction with the learning curve. The European Organization for Research and Treatment of Cancer (EORTC) QoL questionnaires QLQ-C30, STO22, and OG25 were prospectively surveyed during postoperative 1 year for patient subgroups. Results After PSM, grade I pulmonary complication rate was lower in the TLTG group (n = 213) than in the LATG group (n = 111) (0.5% vs. 5.4%, P = 0.007). Other complications were not different between the groups. The learning curve of TLTG was overcome at the 26th case in terms of the comprehensive complication index. The TLTG group after learning curve showed lower grade I pulmonary complication rate than the matched LATG group (0.5% vs. 4.7%, P = 0.024). Regarding postoperative QoL, the TLTG group (n = 63) revealed less dysphagia (P = 0.028), pain (P = 0.028), eating restriction (P = 0.006), eating (P = 0.004), odynophagia (P = 0.023) than the LATG group (n = 21). Multivariate analyses for each QoL item demonstrated that TLTG was the only common independent factor for better QoL. Conclusions TLTG reduced grade I pulmonary complications and provided better QoL in dysphagia, pain, eating, odynophagia than LATG for patients with clinical stage I gastric cancer.

Application value of hand-sewn anastomosis in totally laparoscopic total gastrectomy for gastric cancer

Background Digestive tract reconstruction in totally laparoscopic total gastrectomy can be divided into two types: instrument anastomosis and hand-sewn anastomosis. This study explored the feasibility and safety of hand-sewn sutures in esophagojejunostomy of totally laparoscopic total gastrectomy, compared with instrument anastomosis using an overlap linear cutter. Methods This retrospective cohort study was conducted from January 2017 to January 2020 at one institution. The clinical data of 50 patients who underwent totally laparoscopic total gastrectomy, with an average follow-up time of 12 months, were collected. The clinicopathologic data, short-term survival prognosis, and results of patients in the hand-sewn anastomosis (n=20) and the overlap anastomosis (n=30) groups were analyzed. Results There were no significant differences between the groups in sex, age, body mass index, American Society of Anesthesiologists score, tumor location, preoperative complications, abdominal operation history, tumor size, pTNM stage, blood loss, first postoperative liquid diet, exhaust time, or postoperative length of hospital stay. The hand-sewn anastomosis group had a significantly prolonged operation time (204±26.72min versus 190±20.90min, p=0.04) and anastomosis time (58±22.0min versus 46±15.97min, p=0.029), and a decreased operation cost (CNY 77,100±1700 versus CNY 71,900±1300, p<0.0001). Postoperative complications (dynamic ileus, abdominal infection, and pancreatic leakage) occurred in three patients (15%) in the hand-sewn anastomosis group and in four patients (13.3%) in the overlap anastomosis group (anastomotic leakage, anastomotic bleeding, dynamic ileus, and duodenal stump leakage). Conclusion The hand-sewn anastomosis method of esophagojejunostomy under totally laparoscopic total gastrectomy is safe and feasible and is an important supplement to linear and circular stapler anastomosis. It may be more convenient regarding obesity, a relatively high position of the anastomosis, edema of the esophageal wall, and short jejunal mesentery.

Multivariate analyses for each QoL item demonstrated that TLTG was the only common independent factor for better QoL.Conclusions: TLTG reduced pulmonary complications and provided better QoL in dysphagia, pain, eating, odynophagia than LATG for patients with clinical stage I gastric cancer.

Application of Self-Pulling and Latter Transection in Totally Laparoscopic Total Gastrectomy

Background: To investigate the safety and efficacy of self-pulling and latter transection in totally laparoscopic total gastrectomy (SPLT-TLTG). Methods: Eighty patients with gastric cancer who received either SPLT-TLTG or laparoscopic-assisted total gastrectomy (LATG) were enrolled for this study from January 2016 to June 2018. Clinical data including clinicopathologic parameters, postoperative conditions and long-term prognosis were collected and compared between patients received different types of surgeries. Results: Compared to LATG, patients who received SPLT-TLTG surgery were associated with shorter operation time, less intraoperative blood loss and smaller incision lesion. In addition, patients who received SPLT-TLTG surgeries spent significantly less time in bed-rest post-surgically, to first bowel movement, hospital stay and before first oral food-intake (P < 0.05), as long as lower postoperative pain scores. However, no significant difference was observed between SPLT-TLTG and LATG surgeries in terms of how many lymph nodes (LNs) were retrieved during operation, as well as the overall incidence of postoperative complications (P > 0.05). Conclusions: This pilot study provided primary evidence for the application of self-pulling and latter transection in totally laparoscopic total gastrectomy in the treatment of gastric cancer.

Modified π-shaped Esophagojejunostomy in Totally Laparoscopic Total Gastrectomy: a Report of 40 Consecutive Cases From a Single Center

Background: Intracorporeal esophagojejunostomy remains a challenging technique in totally laparoscopic total gastrectomy (TLTG) without established standard anastomosis method. π-shaped esophagojejunostomy in TLTG was reported to be safe and feasible. Therefore, this study aimed to depict our modified π-shaped esophagojejunostomy in TLTG and evaluate its short-term surgical outcomes.Methods: From April 2018 to October 2019, 40 patients with gastric cancer who underwent TLTG by the same surgeon with modified π-shaped esophagojejunostomy were enrolled. Clinicopathologic data including age, gender, body mass index, American Society of Anesthesiologists score, tumor size, tumor location, depth of tumor invasion, number of harvested lymph nodes, nodal metastasis and TNM stage, operative time, estimated blood loss, time to resume diet, postoperative hospital stays, complication, and mortality were collected and retrospectively analyzed.Results: The mean operative time and estimated blood loss were 264.6 ± 56.9 min and 68.5 ± 53.3 mL, respectively. Postoperative flatus occurred at 4.6 ± 1.7 days. The mean time to resume diet was 7.4 ± 1.7 days postoperatively. One patient was diagnosed with anastomotic leakage and managed with conservative therapy. Pleural effusion, occurring in 4 (10%) patients, was the most common complication. One patient experienced intra-abdominal bleeding requiring reoperation. Other complications were atrial fibrillation and wound infection. No mortality occurred during the 6-month follow-up.Conclusions: Modified π-shaped esophagojejunostomy is a safe and feasible method for intracorporeal anastomosis in TLTG, which showed favorable surgical outcomes.
