Effects of perioperative low-dose naloxone on the immune system in patients undergoing laparoscopic-assisted total gastrectomy: a randomized controlled trial

BackgroundLow immune function after laparoscopic total gastrectomy puts patients at risk of infection-related complications. Low-dose naloxone (LDN) can improve the prognosis of patients suffering from chronic inflammatory diseases or autoimmune diseases. The use of LDN during perioperative procedures may reduce perioperative complications. The purpose of this study was to examine the effects of LDN on endogenous immune function in gastric cancer patients and its specific mechanisms through a randomized controlled trial.MethodsFifty-five patients who underwent laparoscopic-assisted total gastrectomy were randomly assigned to either a naloxone group (n = 23) or a nonnaloxone group (n = 22). Patients in the naloxone group received 0.05 µg/kg-1.h− 1naloxone from 3 days before surgery to 5 days after surgery via a patient-controlled intravenous injection (PCIA) pump, and patients in the nonnaloxone group did not receive special treatment. The primary outcomes were the rates of postoperative complications and immune function assessed by NK cell, CD3+ T cell, CD4+ T cell, CD8+ T cell, WBC count, neutrophil percentage, and IL-6 and calcitonin levels. The secondary outcomes were the expression levels of TLR4 (Toll-like receptor), IL-6 and TNF-α in gastric cancer tissue.ResultsCompared with the nonnaloxone group, the naloxone group exhibited a lower incidence of infection (in the incision, abdomen, and lungs) (P < 0.05). The numbers of NK cells and CD8+ T cells in the naloxone group were significantly greater than those in the nonnaloxone group at 24 h after surgery (P < 0.05) and at 96 h after surgery (P < 0.05). Compared with those in the nonnaloxone group, the CD3 + T-cell (P < 0.05) and CD4 + T-cell (P < 0.01) counts were significantly lower in the naloxone group 24 h after surgery. At 24 h and 96 h after surgery, the WBC count (P < 0.05) and neutrophil percentage (P < 0.05) were significantly greater in the nonnaloxone group. The levels of IL-6 (P < 0.05) and calcitonin in the nonnaloxone group were significantly greater at 24 h after surgery. At 24 h following surgery, the nonnaloxone group had significantly greater levels of IL-6 (P < 0.05) and calcitonin than did the naloxone group. Compared with those in the naloxone group, the expression levels of TLR4 (P < 0.05) in gastric cancer tissue in the naloxone group were greater; however, the expression levels of IL-6 (P < 0.01) and TNF-α (P < 0.01) in the naloxone group were greater than those in the nonnaloxone group.ConclusionLaparoscopic total gastrectomy patients can benefit from 0.05 ug/kg− 1. h− 1 naloxone by reducing their risk of infection. It is possible that LDN alters the number of cells in lymphocyte subpopulations, such as NK cells, CD3 + T cells, and CD4 + T cells, and the CD4+/CD8 + T-cell ratio or alters TLR4 receptor expression in immune cells, thereby altering immune cell activity.Trial registrationThe trial was registered at the Chinese Clinical Trial Registry on 24/11/2023 (ChiCTR2300077948).

Safety and effectiveness of totally laparoscopic total gastrectomy vs laparoscopic-assisted total gastrectomy: a meta-analysis.

For gastric cancer with total gastrectomy, the usual laparoscopic surgical approaches are totally laparoscopic total gastrectomy (TLTG) and laparoscopic-assisted total gastrectomy (LATG). Due to its difficult anastomotic technique, the adoption of TLTG is limited. Therefore, surgeons prefer using LATG, which also led to TLTG being somewhat overlooked, so there is no clear conclusion today as to which surgical procedure is more favorable to the patient's recovery. This article aimed to compare the safety and short-term outcomes of the two surgical approaches. Studies comparing TLTG and LATG, published up to December 2022, were searched in PubMed, Web of Science, and Embase databases. The study outcomes, including operative time, blood loss, anastomosis time, number of retrieved lymph nodes, proximal and distal resection margins, time to first fluid and soft diet, hospitalization duration, time to first flatus, and postsurgical and anastomotic complications, were compared between these two different surgical procedures. Statistics were analyzed with RevMan 5.4 and Stata 13.1. Fifteen publications were included in this study. The total sample included 3023 cases. The meta-analysis revealed no significant difference in overall postoperative complications between the two surgical approaches ( P >0.05). Compared with LATG, TLTG led to reduced intraoperative blood loss ( P <0.0001), an increased number of lymphatic node dissections ( P <0.0001), and decreased hospitalization duration ( P =0.002). However, operative time, anastomosis time, pulmonary infection, resection margins, time to first fluid and soft diet, time to first flatus and anastomosis-related complications were no significant difference between TLTG and LATG groups ( P >0.05). TLTG did not lead to an increase in overall postoperative complications, which is a reliable surgical approach for treatment of gastric cancer. Moreover, it may reduce harm to patients and enable them to obtain better surgical outcomes.

Application of self-pulling and latter transection in totally laparoscopic total gastrectomy.

Recent years have seen an increase in gastric cancer incidence. The most effective method of treating gastric cancer is still surgical resection. Over the past few decades, minimally invasive surgery has rapidly developed, reducing post-operative complications and speeding up recovery. However, the technical difficulties, especially during anastomosis, hinder the widespread use of this advanced surgery. The aim of this study was to investigate the safety and efficacy of self-pulling and latter transection in totally laparoscopic total gastrectomy (SPLT-TLTG). A retrospective study compared the outcomes of laparoscopic-assisted total gastrectomy (LATG) and SPLT-TLTG in patients with gastric cancer. Eighty patients who underwent either LATG or SPLT-TLTG between January 2016 and June 2018 were included in the study. Clinical information was used to compare patients who underwent these surgeries. Compared to LATG, patients who received SPLT-TLTG surgery recovered faster than those who received LATG time (operation and digestive tract reconstruction), blood loss, rehabilitation, first flatus, oral food intake, average pain score and hospital stay were significantly shorter in the SPLT-TLTG group than in the LATG group (P < 0.05). However, the two groups had no significant differences in LNs and baseline characteristics. The findings of this study provide significant evidence in support of the use of self-pulling and the latter transection procedures in total laparoscopic gastrectomy.

Effectiveness and safety of self-pulling and latter transected reconstruction in totally laparoscopic total gastrectomy: a comparison with laparoscopic-assisted total gastrectomy

BackgroundIn some earlier studies, self-pulling and later transection (SPLT) esophagojejunostomy (E-J) was incorporated into total laparoscopic total gastrectomy (TLTG) procedures. Its effectiveness and safety, however, remain unknown. This study compared (SPLT)-E-J in TLTG with conventional E-J in laparoscopic-assisted total gastrectomy (LATG) in order to assess the short-term safety and efficacy of (SPLT)-E-J in TLTG.MethodsThis research analyzed patients with gastric cancer who received SPLT-TLTG or LATG between January 2019 and December 2021 in the First Affiliated Hospital of Chongqing Medical University. Baseline data and postoperative short-term surgical outcomes were obtained retrospectively and compared between the two groups.ResultsA total of 83 patients who underwent SPLT-TLTG (n = 40, 48.2%) or LATG (n = 43, 51.8%) were included in this study. There were no differences between the two groups in terms of patient demographics or tumor characteristics. No statistically significant differences were observed between the two groups in terms of operation time, intraoperative blood loss, harvested lymph nodes, postoperative complications, postoperative decrease in hemoglobin and albumin levels, or postoperative hospital stay. Five and seven patients experienced short-term postoperative complications in the SPLT-TLTG and LATG groups, respectively.ConclusionsSPLT-TLTG is a dependable and safe surgical method for the treatment of gastric cancer. Its short-term outcomes were similar to those of conventional E-J in LATG and had advantages regarding surgical incision and simplification of reconstruction.

Overlapping Esophagojejunostomy Using a Linear Stapler in Laparoscopic Total or Proximal Gastrectomy.

Background: Performing an intracorporeal esophagojejunostomy during laparoscopic-assisted total or proximal gastrectomy is challenging. We developed an ingenious method of overlapping esophagojejunostomy using a linear stapler to avoid stapler-related intraoperative complications. Methods: Following lymph node dissection, the esophagus was transected anterior-posteriorly. A linear stapler was used to divide the jejunum ∼20 cm distal to the Treitz ligament. A small enterotomy was then created 5 cm distal to the elevated jejunal stump to insert the linear stapler cartridge. An electronic knife was used to make a full-thickness incision, with the tip of the nasogastric tube (NGT) pressed against the posterior wall of the esophageal stump as a guide. Full-thickness sutures were placed on both the anterior and posterior walls of the entry hole in the esophageal stump to prevent the anvil fork from being misinserted into the submucosal layer of the esophagus. The thread on the posterior wall was guided through the port to the outside of the abdominal cavity, where the linear stapler was inserted to perform the side-to-side anastomosis. A 45-mm cartridge fork and an anvil fork were inserted into the elevated jejunum and esophageal stump entry holes, respectively, following which the esophageal stump was gently grasped. The thread on the posterior wall side was pulled from outside the abdominal cavity through the port. This step is necessary to close the gap between the esophageal and jejunal walls. After confirming that the anvil fork was not misinserted into the submucosal layer of the esophagus and that there was no gap between the esophagus and the elevated jejunum, the linear stapler was fired to create the anastomosis. The insertion hole was closed with hand-sewn sutures or linear staples to complete the esophagojejunostomy. Results: Eleven patients underwent this procedure with no anastomotic complications. Conclusions: This method enables us to perform an easier and more stable esophagojejunostomy.

Learning curve of laparoscopic and robotic total gastrectomy: A systematic review and meta-analysis.

Minimally-invasive total gastrectomy (MITG) is associated with lower morbidity in comparison to open total gastrectomy but requires a learning curve (LC). We aimed to perform a pooled analysis of the number of cases required to surmount the LC (NLC) in MITG. A systematic review of PubMed, Embase, Scopus and the Cochrane Library from inception until August 2022 was performed for studies reporting the LC in laparoscopic total gastrectomy (LTG) and/or robotic total gastrectomy (RTG). Poisson mean (95% confidence interval [CI]) was used to determine the NLC. Negative binomial regression was performed as a comparative analysis. There were 12 articles with 18 data sets: 12 data sets (n = 1202 patients) on LTG and 6 data sets (n = 318 patients) on RTG. The majority of studies were conducted in East Asia (94.4%). The majority of the data sets (n = 12/18, 66.7%) used non-arbitrary analyses. The NLC was significantly smaller in RTG in comparison to LTG [RTG 20.5 (95% CI 17.0-24.5); LTG 43.9 (95% CI 40.2-47.8); incidence rate ratio 0.47, p < 0.001]. The NLC was comparable between totally-laparoscopic total gastrectomy (TLTG) and laparoscopic-assisted total gastrectomy (LATG) [LATG 39.0 (95% CI 30.8-48.7); TLTG 36.0 (95% CI 30.4-42.4)]. The LC for RTG was significantly shorter for LTG. However existing studies are heterogeneous.

Long-term outcomes after laparoscopy-assisted total or proximal gastrectomy with nodal dissection for clinical stage I gastric cancer: Japan Clinical Oncology Group study (JCOG1401).

305 Background: JCOG0912 supports the non-inferiority of laparoscopy-assisted distal gastrectomy (LADG) compared with open distal gastrectomy (ODG) for clinical stage I gastric cancer relapse-free survival (RFS), suggesting that LADG should be considered a standard treatment option when performed by experienced surgeons. No prospective study evaluating laparoscopy-assisted total gastrectomy (LATG) and laparoscopy-assisted proximal gastrectomy (LAPG) has been completed in terms of both safety and long-term survival. Considering that the results of the phase III trial to evaluate the long-term outcome of LADG (JCOG0912) could guarantee that of LATG/LAPG, we conducted a single-arm confirmatory trial (JCOG1401) to evaluate the safety of LATG/LAPG for clinical stage I proximal gastric cancer and JCOG1401 confirmed the safety of LATG/LAPG. Long-term outcomes as the secondary endpoints of this study are reported here after 5-year follow-up period. Methods: Laparoscopic operators were limited to credentialed surgeons. The extent of nodal dissection was selected based on the Gastric Cancer Treatment Guidelines in Japan. The primary endpoint was the proportion of grade 2 (CTCAE ver. 4.0) or greater esophageal anastomotic leak. The sample size was determined to be 245 considering a threshold of 8% and expected value of 3% with a one-sided alpha error of 2.5% and statistical power of 90%. The secondary endpoints were overall survival (OS) and RFS. Results: Between April 2015 and February 2017, 245 patients were enrolled. Among them, 1 patient was excluded from safety analysis due to ineligible. LATG/LAPG was performed in 195/49. 170/47/17/8/2 patients had pStage IA/IB/II/IIIA/IIIB disease and 190/31/15/8 patients had pT1/T2/T3/T4 disease, respectively. Grade 2 or greater esophageal anastomotic leak was 2.5% (6/244) (95% CI 0.9-5.3), as previously reported. 5-year OS was 91.2% (95% CI 86.9-94.2). 5-year RFS was 90.0% (95% CI 85.5-93.2). Among 22 deaths, 14 patients died without recurrence and 8 patients died with recurrence. Twelve recurrences were observed in 5/2/4/1 patients for pT1/T2/T3/T4. The sites of recurrence were peritoneal metastasis in 2 cases, hematogenous metastasis in 9 cases (liver: 6, bone: 2, lung: 1), and other in 1 case. Conclusions: The long-term outcomes of LATG/LAPG for Stage I gastric cancer patients were excellent and seem comparable to those of open procedures. Similar to JCOG0912, JCOG1401 guarantee the long-term survival of LATG/LAPG. Clinical trial information: UMIN000017155 .

Patient-Reported Outcomes of Individuals with Gastric Cancer Undergoing Totally Laparoscopic Versus Laparoscopic-Assisted Total Gastrectomy: A Real-World, Propensity Score-Matching Analysis.

Totally laparoscopic total gastrectomy (TLTG) and laparoscopic-assisted total gastrectomy (LATG) are two types of minimally invasive radical gastrectomy procedures to treat gastric cancer (GC). This study compared the long-term prognosis and postoperative health-related quality of life (HRQoL) between TLTG and LATG. A total of 106 patients who underwent TLTG and 1,076 patients who underwent LATG at the Union Hospital of Fujian Medical University (Fuzhou, China) between January 2014 and April 2018 were included in the propensity score matching (PSM, 1:2). Patient-reported outcomes at 3, 6, and 12 months after gastrectomy were analyzed. The questionnaire referred to the European Organization for Research and Treatment of Cancer (EORTC) 30-item core QoL (QLQ-C30)and the GC module (QLQ-STO22) questionnaire. After PSM, there were no significant differences in clinicopathological characteristics between the TLTG (n = 104) and the LATG groups (n = 208). Operative time and volume of blood loss were significantly lower in the TLTG group than in the LATG group. Kaplan-Meier survival analysis revealed similar 3-year survival rates between the TLTG and LATG groups (83.7 vs. 80.3%, respectively; P = 0.462). Tolerance to nonliquid diet, decrease in body weight, and albumin levels were also significantly lower in the TLTG group than in the LATG group (all P < 0.05). The HRQoL scale demonstrated that the overall score in the TLTG group was better than that in the LATG group at 3, 6, and 12 months after gastrectomy (all P < 0.05). Patients with GC undergoing TLTG reported better HRQoL and experienced faster recovery of social function than those undergoing LATG, although the two groups demonstrated similar short-term outcomes and long-term prognosis.

Complication Rates in Different Gastrectomy Techniques of Enhanced Recovery after Surgery for Gastric Cancer: A Meta-analysis.

The purpose of this study was to analyse the postoperative complications of different gastrectomy methods, and provides guidance for the development of enhanced recovery after surgery (ERAS) protocols. We searched EMBASE, Web of Science, CINAHL, PubMed, MEDLINE, and the Cochrane Central Register of Controlled Trials for articles published from database inception to January 30, 2020. Statistical analysis was performed using R version 3.6.3 with single-rate meta-analysis. A total of 22 studies with 2127 patients were included. The types of postoperative complications showed that the pooled rate of nausea and vomiting was 10.22% (95% CI 4.56 to 17.48) and the pancreatic fistula was 3.58% (2.12 to 5.35) often occurred in patients who underwent laparoscopic gastrectomy (LG). After open gastrectomy (OG), postoperative urinary retention was 3.88% (0.00 to 13.17) and pancreatic fistula was 3.81% (1.78 to 6.42). The main complications of laparoscopic-assisted total gastrectomy and laparoscopic-assisted subtotal gastrectomy were pneumonia and pancreatic fistula, the rate was 3.19% (0.94 to 0.637) and 3.06% (0.11 to 8.36), respectively. In order to reduce the incidence of complications, ERAS should be revised from the aspects of rehabilitation, intraoperative application of new technology, shortening the operation time, early detection of high-risk groups, and implementation of audit. Key Words: Enhanced recovery after surgery, Gastric cancer, Postoperative complications.

Comparison of short-term efficacy between totally laparoscopic gastrectomy and laparoscopic assisted gastrectomy for elderly patients with gastric cancer.

BACKGROUNDTotally laparoscopic gastrectomy (TLG) entails both gastrectomy and gastrointestinal reconstruction under laparoscopy. Compared with laparoscopic assisted gastrectomy (LAG), TLG has been demonstrated in many studies to require a smaller surgical incision, result in a faster postoperative recovery and less pain and have comparable long-term efficacy, which has been a research hotspot in recent years. Whether TLG is equally safe and feasible for elderly patients remains unclear.AIMTo compare the short-term efficacy of and quality of life (QOL) associated with TLG and LAG in elderly gastric cancer (GC) patients.METHODSThe clinicopathological data of 462 elderly patients aged ≥ 70 years who underwent LAG or TLG (including distal gastrectomy and total gastrectomy) between January 2017 and January 2022 at the Department of General Surgery, First Medical Center, Chinese PLA General Hospital were retrospectively collected. A total of 232 patients were in the LAG group, and 230 patients were in the TLG group. Basic patient information, clinicopathological characteristics, operation information and QOL data were collected to compare efficacy.RESULTSCompared with those in the LAG group, intraoperative blood loss in the TLG group was significantly lower (P < 0.001), and the time to first flatus and postoperative hospitalization time were significantly shorter (both P < 0.001). The overall incidence of postoperative complications in the TLG group was significantly lower than that in the LAG group (P = 0.01). Binary logistic regression results indicated that LAG and an operation time > 220 min were independent risk factors for postoperative complications in elderly patients with GC (P < 0.05). In terms of QOL, no statistically significant differences in various preoperative indicators were found between the LAG group and the LTG group (P > 0.05). Compared with the laparoscopic-assisted total gastrectomy group, patients who received totally laparoscopic total gastrectomy had lower nausea and vomiting scores and higher satisfaction with their body image (P < 0.05). Patients who underwent laparoscopic-assisted distal gastrectomy were more satisfied with their body image than patients in the totally laparoscopic distal gastrectomy group (P < 0.05).CONCLUSIONTLG is safe and feasible for elderly patients with GC and has outstanding advantages such as reducing intracorporeal blood loss, promoting postoperative recovery and improving QOL.

Quality of life after totally laparoscopic versus laparoscopic-assisted total gastrectomy: a retrospective cohort study with propensity score matching

Objective: To evaluate the postoperative quality of life in patients after totally laparoscopic total gastrectomy (TLTG). Methods: A retrospective cohort study based on propensity score matching was performed. Clinical and follow-up data of patients who underwent laparoscopic radical gastrectomy at Union Hospital of Fujian Medical University from January 2014 to May 2015 were collected. Case indusion criteria: (1) primary gastric cancer confirmed by postoperative pathology; (2) receiving TLTG or laparoscopic-assisted total gastrectomy (LATG);(3) R0 resection; (4) completing follow-up for 12 months and complete follow-up data. Exclusion criteria: (1) gastric stump cancer; (2) concurrent tumor; (3) distal metastasis found during operation; (4) history of upper abdominal operation. According to surgical procedures, patients were divided into the LATG group (1076 cases) and the TLTG group (106 cases). To eliminate potential bias in baseline data between the two groups, the propensity score was calculated using a logistic regression model with the following covariates, including age, sex, body mass index, American Society of Anesthesiologists score, tumor location, tumor size, pathology type, and stage. The two groups were matched using a 1:2 propensity assessment ratio and a caliper width of 0.01 standard deviation was specified. The primary outcomes were the quality of life of the two groups at 3, 6 and 12 months after gastrectomy, including physical symptoms and social function. Higher function score indicated better function, and higher symptom score presented worse symptoms. Quality of life score = (100 - somatic symptom scale score + social function scale score) / 2. The secondary outcomes were postoperative nutritional recovery and food tolerance at 3, 6 and 12 months after gastrectomy. The categorical variables were expressed as n(%), and compared using the χ2 test or Fisher exact test. The continuous variables conforming to the normal distribution were represented by Mean ± SD and compared with the paired t-test. Repeated measurement of variance was used to compare nutrition-related indicators within the group among pre-operation, postoperative 1, 3, 6, 12 months. Results: After PSM, there were no significant differences in clinicopathological baseline data between the TLTG group (n=104) and the LATG group (n=208) (all P>0.05). The physical symptoms scores in the TLTG group before operation and 3, 6 and 12 months after operation were 8.6±5.8, 15.5±8.4, 10.1±5.9 and 6.1±2.4 respectively (F=43.493, P<0.001). In the LATG group, the above mentioned scores were 9.7±6.9, 23.7±10.4, 13.3±8.3 and 8.5±4.2 respectively (F=112.588, P<0.001). Compared with the LATG group, the symptom scores in the TLTG group were lower at 3 and 6 months after operation, and the differences were statistically significant (t=-3.653, P<0.001; t=-2.513, P=0.012). At 12 months after operation, although the physical symptom score in the TLTG group was also lower than that in LATG group, the difference was not statistically significant (t=-1.487, P=0.138). The social function scores in the TLTG group before operation and 3, 6 and 12 months after operation were 90.3±8.9, 77.5±14.3, 87.4±10.3 and 91.7±6.7 respectively (F=28.524, P<0.001). In the LATG group, the above mentioned scores were 92.5±6.3, 68.5±16.8, 79.8±14.7 and 84.7±11.1 respectively (F=57.975, P<0.001). Compared with the LATG group, the social function scores of patients in the LATG group were higher at 3, 6 and 12 months after operation (t=3.543, P<0.001; t=3.216, P=0.001; t=2.235, P=0.026). The total scores of quality of life at 3, 6 and 12 months after operation in the TLTG group were 81.0±15.6, 88.3±8.1 and 93.3±9.1 respectively, and the above mentioned scores in the LATG group were 72.4±13.6, 83.3±11.5 and 88.1±7.7 respectively, whose differences at corresponding time point were all significant between the two groups (all P<0.05). The change of total body mass[(-8.4±1.4)% vs. (-13.2±1.6)%, t=2.273, P=0.024], serum albumin[(-5.1±0.7)% vs. (-7.4±0.8)%,t=2.095, P=0.037], meal quantity [(-15.6±4.7)% vs. (-24.1±6.0)%, t=2.885, P=0.004] and meal times [(20.8±7.1)% vs. (30.6±11.5)%, t=3.043, P<0.001] in the TLTG group were significantly lower than those in the LATG group one year after operation (all P<0.05). At 3, 6 and 12 months after operation, the diet proportions of solid and soft food in the TLTG group were higher than those in the LATG group (all P<0.05). Conclusions: Compared with LATG, patients with gastric cancer undergoing TLTG have better health-related quality of life and faster recovery of nutrition.

Technical details of gastrointestinal reconstruction using linear stapler in totally laparoscopic total gastrectomy

With the development of instrument, equipment and surgical skills, especially the emergence of a series of high-level medical evidence, the laparoscopic techniques in the field of gastric surgery has been further expanded. Totally laparoscopic total gastrectomy (TLTG) has certain technical difficulties, and more challenges are reflected in the digestive tract reconstruction. The use of linear staplers has reduced the difficulty of digestive tract reconstruction to a certain extent and has strongly promoted the transition from laparoscopic-assisted total gastrectomy to TLTG. However, for TLTG, there are still many details that should be carefully concerned, so as to effectively avoid the surgical pitfalls and ensure the fluency and safety of the procedure. In this article, we discuss the surgical details based on our own experiences, including how to obtain surgical field exposure well, how to manage specific accidents when using linear stapler for esophagojejunostomy, how to prevent intra-abdominal hernias and Roux stasis syndrome, and how to prevent the stapled lines of the esophageal or jejunal stumps from direct contact with aorta.

A comparative study on short-term outcomes and quality of life for gastric cancer patients between totally laparoscopic total gastrectomy using an endoscopic linear stapler and laparoscopic-assisted total gastrectomy using a circular stapler

Objective: To explore the differences of short-term outcomes and quality of life (QoL) for gastric cancer patients between totally laparoscopic total gastrectomy using an endoscopic linear stapler and laparoscopic-assisted total gastrectomy using a circular stapler. Methods: A retrospective cohort study was conducted. Clinicopathological data of patients with stage I to III gastric adenocarcinoma who underwent laparoscopic total gastrectomy from January 2017 to January 2020 were retrospectively collected. Those who were ≥80 years old, had serious complications that could affect the quality of life, underwent multi-organ resections, palliative surgery, emergency surgery due to gastrointestinal perforation, obstruction, bleeding, died or lost to follow-up within 1 year after surgery were excluded. A total of 130 patients were enrolled and divided into circular stapler group (CS group, 77 cases) and linear stapler group (LS group, 53 cases) according to the surgical method. The differences of age, gender, body mass index, number of comorbidities, history of abdominal surgery, ASA, tumor location, degree of differentiation, tumor length, tumor T stage, tumor N stage, tumor pathological stage and preoperative quality of life between the two groups were not statistically significant (all P>0.05). The observation indicators: (1) Surgery and postoperative conditions. (2) Postoperative complications: Any adverse conditions that require conservative treatment or surgical intervention after surgery were defined as postoperative complications, of which, complications occurring within 30 days after surgery were defined as early complications; complications occurring within 30 days to 1 year after surgery were defined as late complications. (3) Postoperative quality of life was assessed by the quality of life core scale (QLQ-C30) and gastric cancer specific module scale (QLQ-STO22). The higher the scores of functional scales and global health status, the better the corresponding quality of life. The higher the scores of symptoms scales, the worse the corresponding quality of life. Results: (1) Surgery and postoperative conditions: Compared with the CS group, the LS group presented less intraoperative blood loss [50.0 (50.0-100.0) ml vs. 100.0 (100.0-100.0) ml, Z=-3.111, P=0.002] and earlier time to flatus [(3.1±0.8) days vs. (3.5±1.1) days, t=-2.490, P=0.014]. However, there were no statistically significant differences between two groups of patients in terms of operation time, time to start a liquid diet and postoperative hospital stay (all P>0.05). (2) Postoperative complications: The early complication rates of the CS group and the LS group were 22.1% (17/77) and 18.9% (10/53), respectively, while the late complication rate were 18.2% (14/77) and 15.1% (8/53), respectively, whose differences were not statistically significant (all P>0.05). (3) Postoperative quality of life: After 1-year follow-up, 7 (5.4%) patients were lost, including 5 in CS group and 2 in LS group. One year after operation, the QLQ-C30 scale showed that the score of financial difficulty of the LS group was significantly higher than that of the CS group [33.3 (0 to 33.3) vs.0 (0 to 33.3), Z=-1.972, P=0.049] with statistically significant difference, and there were no statistically significant differences in the scores of other functional fields and symptom fields between the two groups (all P>0.05). The QLQ-STO22 scale showed that the scores of dysphagia [0 (0 to 5.6) vs. 0 (0 to 11.1), Z=-2.094, P=0.036] and eating restriction were significantly lower [0 (0 to 4.2) vs. 0 (0 to 8.3), Z=-2.011, P=0.044] in patients of the LS group than those of the CS group. There were no significant differences in scores of other symptoms between two groups (all P>0.05). Conclusions: Compared with the circular stapler, the esophagojejunostomy with linear stapler for gastric cancer patients can reduce intraoperative blood loss, shorten the time to flatus after operation, alleviate the symptoms of dysphagia and eating restriction but increase the economic burden to a certain degree.

Observation on the Therapeutic Effect and Complication Rate of Totally Laparoscopic Total Gastrectomy and Laparoscopic-Assisted Total Gastrectomy in the Treatment of Gastric Cancer

Objective: To investigate the effect and complication rate of totally laparoscopic and laparoscopic-assisted total gastrectomy in the treatment of gastric cancer. Methods: From March 2019 to July 2021, 60 patients with gastric cancer were selected as the subjects in this study; the patients in group A underwent laparoscopic-assisted total gastrectomy, whereas those in group B underwent totally laparoscopic total gastrectomy; the treatment effect and complication rate were compared between the two groups. Results: The postoperative recovery of group B was significantly better than that of group A, and the postoperative complications (10.00%) of group B were significantly lower than that of group A (33.33%) (P &lt; 0.05). Conclusion: For patients with gastric cancer, totally laparoscopic total gastrectomy has better therapeutic effect and lower postoperative complications, which is worthy of popularization.

Totally laparoscopic total gastrectomy using the "enjoyable space" approach coupled with self-pulling and latter transection reconstruction versus laparoscopic-assisted total gastrectomy for upper gastric cancer: short-term outcomes.

IntroductionWith the development of minimally invasive surgery in recent years, totally laparoscopic total gastrectomy (TLTG) has attracted more attention.AimTo introduce the more comprehensive “enjoyable space” approach coupled with the self-pulling and latter transaction (SPLT) reconstruction technique to perform TLTG and investigate its safety and feasibility.Material and methodsNinety-seven patients with primary upper gastric cancer underwent laparoscopic radical total gastrectomy between January 2020 and December 2020. Among these patients, 46 underwent laparoscopic-assisted total gastrectomy (LATG), and 51 underwent TLTG. We compared the clinicopathological characteristics, surgical outcomes and postoperative complications between the two groups.ResultsThere were no significant differences in the clinicopathological characteristics between the two groups (p > 0.05). However, the TLTG group had a slightly lower mean operative time and mean blood loss than the LATG group (p < 0.05 each). Although there were similarities in the mean times to first flatus, liquid diet, and soft diet, the duration of hospital stay was significantly reduced in the TLTG group (p < 0.05). No significant differences in overall complications and E-J-related complications were found between the two groups (15.2% vs. 25.4%, p > 0.05).ConclusionsTLTG is a safe and feasible procedure for treating upper gastric cancer. The enjoyable space approach in conjunction with SPLT reconstruction is an appropriate comprehensive technique with several advantages over LATG.

Art in Endoscopy: Bridge over anastomotic stoma.

This image is from a patient who had undergone laparoscopic-assisted total gastrectomy 2 years previously for low-differentiation gastric adenocarcinoma. A large and thick mucosal bridge was found above the anastomotic stoma. Reality is this shore, the ideal is the other shore. The bridge at least means hope and success, no matter where it appears.

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

BackgroundThis 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.MethodsFrom 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.ResultsAfter 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.ConclusionsTLTG reduced grade I pulmonary complications and provided better QoL in dysphagia, pain, eating, odynophagia than LATG for patients with clinical stage I gastric cancer.

Digestive tract reconstruction of laparoscopic total gastrectomy for gastric cancer: a comparison of the intracorporeal overlap, intracorporeal hand-sewn anastomosis, and extracorporeal anastomosis.

The application of esophagojejunostomy has certain difficulties in totally laparoscopic total gastrectomy (TLTG). This is due to the higher requirement for surgical techniques and the lack of any unified standards. This study aim to explore the practicability and safety of intracorporeal overlap and intracorporeal hand-sewn anastomosis compared with extracorporeal anastomosis. The clinical pathological data of 56 patients who underwent TLTG from March 2016 to December 2020 in the Harbin Medical University Cancer Hospital were retrospectively analyzed. According to the method of anastomosis, the patients were divided into the overlap (n=36) and the hand-sewn anastomosis (n=20). Patients who receive laparoscopic-assisted total gastrectomy (LATG; n=74) formed the control group. The basic clinical data, and intraoperative and postoperative results of the patients were assessed. Compared with the control group, the overlap anastomosis and hand-sewn anastomosis groups showed no significant differences in clinicopathological data and short-term postoperative recovery. There were no significant differences between the overlap and the control group in operation time nor anastomosis time. However, the anastomosis time of the hand-sewn anastomosis group was significantly prolonged compared to the control group (53.20±14.14 vs. 43.01±12.53 minutes, P=0.002). Compared with the control group, the operation cost was significantly higher in the overlap group (CNY 81,300±6,100 vs. CNY 76,600±6,800, P=0.001), but significantly lower in the hand-sewn anastomosis group (CNY 71,900±1,700 vs. CNY 76,600±6,800, P=0.003). Early postoperative complications occurred in 5 cases (13.9%) in the overlap group, 3 cases (15.0%) in the hand-sewn anastomosis group, and 11 cases (14.9%) in the control group. There were 3 cases (8.3%) of postoperative anastomotic-related complications in the overlap group. No anastomotic-related complications were observed in the hand-sewn anastomosis group. The overlap anastomosis and hand-sewn anastomosis are practical and safe. Furthermore, the overlap anastomosis may be more suitable for patients with lower cardia and fundic lesions. The hand-sewn method has a wider range of indications pending advanced surgical skills, and is an effective supplementary technique for instrument anastomosis.
