Laparoscopic versus open total gastrectomy for T4a gastric cancer: a propensity score-matched analysis of long-term outcomes.

Evidence of implementation of laparoscopic total gastrectomy (LTG) for surgical T4a stage (sT4a) gastric cancer (GC) remains inadequate. This study aimed to compare short- and long-term outcomes of LTG versus open total gastrectomy(OTG) for sT4a GC. This retrospective cohort study was conducted using data from patients with sT4a GC underwent total gastrectomy from 2014 to 2020. Short-term outcomes included operative characteristics and postoperative complications. Long-term oncological outcomes focused on 3-, and 5-year overall survival (OS) and disease-free survival (DFS). Propensity score matching (PSM) was applied to reduce potential biases in baseline characteristics between groups. There was a total of 161 patients, in which 96 underwent LTG and 65 underwent OTG. After PSM, both groups consisted of 51 patients each, with balanced baseline characteristics. There were no significant differences between the two groups regarding blood loss, length of proximal resected margin, postoperative hospital stays, and overall and major postoperative complications. Most of the complications were classified as minor according to the Clavien-Dindo classification. Operating time was significantly longer in the LTG group (mean: 257min vs. 231min, p = 0.006). LTG was superior to OTG groups in time to flatus (mean: 3.0 days vs 3.9 days, p < 0.001). Five-year OS and DFS rates were similar between the two groups (44% and 33% vs. 43% and 28% in the LTG and OTG groups, respectively). Our findings indicate that LTG is a feasible and safe technique, exhibiting comparable long-term oncological outcomes to OTG for sT4a GC. LTG may be an acceptable alternative to OTG for the treatment of sT4a GC.

Standardized procedure for preventing late intestinal complications following minimally invasive total gastrectomy for gastric cancer: a single-center retrospective cohort study.

Although minimally invasive total gastrectomy for gastric cancer is commonly performed, reports regarding late complications are limited. We have made several improvements each time we experienced severe late complications since 2009. This study aimed to evaluate the clinical efficacy of these improved procedures in preventing late complications. Between January 2009 and December 2019, 302 patients who underwent laparoscopic or robotic total gastrectomy for gastric cancer were enrolled. The patients were divided into two groups: Period-I (2009-2013, before established standardization of procedure, 166 patients) and Period-II (2014-2019, after established standardization of procedure, 136 patients). The standardized procedure comprised four major steps, including closure of the mesentery defects and diaphragm crus, circumferential fixation of the anastomotic site into the diaphragm, and linearization around the anastomotic site of esophagojejunostomy. The incidence of late complications was retrospectively compared between the two groups. Late overall complications that occurred over 30days after surgery were observed in 19 (6.3%) patients. In all, 14 of 24 (58.3%) patients admitted due to late intestinal complications eventually required reoperation for treatment. The most frequent complication was nonstenotic outlet obstruction of the distal jejunal limb. The incidence of late overall complications was significantly lower in Period-II than in Period-I (2.9 vs 9.0%, p = 0.030). Intestinal complications were reduced considerably in Period-II. The 3-year cumulative incidence rate of late overall complications was significantly lower in Period-II than in Period-I (0.03 vs 0.10, p = 0.035). Period-I as the only independent risk factor for the development of late intestinal complications. Late complications after laparoscopic total gastrectomy sometimes occurred, and more than half of the patients with intestinal complications required reoperation. Our standardized procedure was associated with a lower risk of late intestinal complications after minimally invasive total gastrectomy followed by intracorporeal esophagojejunostomy using linear staplers in a cohort of patients with gastric cancer.

Analysis of the safety and efficacy of the self-pulling and latter transected technique in modified overlap anastomosis in total laparoscopic total gastrectomy

BackgroundLaparoscopic total gastrectomy plus lymph node dissection is an effective treatment method for patients with gastric cancer. With the development and popularization of laparoscopic techniques in recent years, surgeons have become more skilled in laparoscopic techniques. Totally laparoscopic total gastrectomy (TLTG) has been developed; however, digestive tract reconstruction remains difficult, especially with anastomosis of the esophagus and jejunum. Using the self-pulling and latter transection (SPLT) method combined with a linear stapler has effectively solved the problem of narrow space in esophagojejunostomy. Here, we examined the safety and effectiveness of the SPLT technique in TLTG compared with SPLT with traditional esophagojejunostomy overlap anastomosis.MethodsWe retrospectively analyzed all patients with gastric cancer admitted to the Department of Gastrointestinal Surgery of the Second Affiliated Hospital of Fujian Medical University from September 2020 to September 2023. In total, 158 patients met the inclusion criteria and were included. Patients were grouped according to whether the lower esophagus was transected after self-pulling. Patient demographics, tumor characteristics, surgical conditions, and postoperative results between the two groups were statistically analyzed.ResultsA total of 158 patients were included in the study. All patients underwent TLTG and completed intracavitary anastomosis. There were 70 cases (44%) in the SPLT-Overlap group and 88 cases (56%) in the traditional overlap group. There was no significant difference in demographic and oncological characteristics between the two groups. The operation time (P = 0.002) and esophageal jejunum anastomosis time (P&amp;lt;0.001) were significantly shorter in the SPLT-Overlap group compared with the traditional overlap group. The intraoperative blood loss of the SPLT-Overlap group was 80.29 ± 36.36 ml, and the intraoperative blood loss of the traditional overlap group was 101.40 ± 46.68 ml. The difference was statistically significant (P=0.003). The SPLT-Overlap group also achieved a higher upper cutting edge (P =0.03). There was no significant difference between the two groups in terms of the incision size, postoperative hospital stay, time to first flatus, time to first liquid intake, drainage tube removal time, and esophagojejunal anastomotic diameter. There were 15 and 19 cases of short-term postoperative complications in the SPLT-Overlap and traditional Overlap groups, respectively. All patients received R0 resection, and no secondary surgery or death occurred.ConclusionWe applied SPLT to overlap anastomosis. Short-term, SPLT has good safety and feasibility in TLTG. It can effectively shorten the time of digestive tract reconstruction, simplify the reconstruction procedure, and make the digestive tract reconstruction simple and fast; at the same time, a safe cutting edge can be obtained.

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).

Laparoscopic Spleen-Preserving Hilar Lymphadenectomy for Advanced Proximal Gastric Cancer Without Greater Curvature Invasion

Splenic hilar lymphadenectomy has been recommended for locally advanced proximal gastric cancer (APGC) involving the greater curvature. However, it is unclear whether laparoscopic spleen-preserving splenic hilar lymphadenectomy (LSPSHL) is associated with a long-term survival benefit for APGC without greater curvature invasion. To present the 5-year follow-up data from a randomized clinical trial that compared laparoscopic total gastrectomy (D2 group) with D2 plus LSPSHL (D2 + No. 10 group) among patients with resectable APGC. This is a post hoc secondary analysis of a randomized clinical trial that enrolled 536 patients with potentially resectable APGC (cT2-4a, N0 or N+, and M0) without greater curvature invasion from January 5, 2015, to October 10, 2018. All patients were tracked for at least 5 years. The final follow-up was on October 30, 2023. Patients were randomly assigned in a 1:1 ratio to the D2 + No. 10 or D2 groups. The 5-year disease-free survival (DFS) and overall survival (OS) rates were measured. Recurrence patterns and causes of death were compared. A total of 526 patients (392 men [74.5%]; mean [SD] age, 60.6 [9.6] years) were included in the modified intent-to-treat analysis, with 263 patients in each group. The 5-year DFS rate was 63.9% (95% CI, 58.1%-69.7%) for the D2 + No. 10 group and 55.1% (95% CI, 49.1%-61.1%) for the D2 group (log-rank P = .04). A statistically significant difference was observed in the 5-year OS between the D2 + No. 10 group and the D2 group (66.2% [95% CI, 60.4%-71.9%] vs 57.4% [95% CI, 51.4%-63.4%]; log-rank P = .03). The No. 10 lymph node exhibited a therapeutic value index (TVI) of 6.5, surpassing that of Nos. 8a (TVI, 3.0), 11 (TVI, 5.8), and 12a (TVI, 0.8). A total of 86 patients in the D2 + No. 10 group (cumulative incidence, 32.7%) and 111 patients in the D2 group (cumulative incidence, 42.2%) experienced recurrence (hazard ratio, 0.72; 95% CI, 0.54-0.95; P = .02). The multivariable competing risk regression model demonstrated that D2 + No. 10 remained an independent protective factor for a lower 5-year cumulative recurrence rate after surgery (hazard ratio, 0.75; 95% CI, 0.56-1.00; P = .05). There was a significant difference in the 5-year cumulative recurrence rate at the No. 10 lymph node area between the 2 groups (D2 + No. 10 group vs D2 group: 0% vs 2.3% [n = 6]; P = .01). This post hoc secondary analysis of a randomized clinical trial found that laparoscopic total gastrectomy with LSPSHL can improve the prognosis and reduce recurrence for APGC without greater curvature invasion. Future multicenter studies are warranted to validate these findings. ClinicalTrials.gov Identifier: NCT02333721.

The safety and feasibility assessment of overlap esophagojejunostomy with self-pulling and latter transection technique in totally laparoscopic total gastrectomy

BackgroundThis study presented an innovative technique in totally laparoscopic total gastrectomy (TLTG) for overlap esophagojejunostomy (E-J), termed self-pulling and latter transection (SPLT) (overlap SPLT). It evaluated the effectiveness and short-term outcomes of this novel method through a comparative analysis with the established functional end-to-end (FETE) E-J incorporating SPLT. MethodsFrom September 2018 to September 2023, this study enrolled 68 patients with gastric cancer who underwent TLTG with overlap SPLT anastomosis and 120 patients who underwent TLTG with FETE SPLT anastomosis. Clinicopathologic characteristics and surgical and postoperative outcomes data for overlap SPLT cases were gathered and retrospectively compared with those from FETE SPLT TLTG to evaluate the effectiveness and clinical safety. ResultsThe duration of anastomosis for overlap SPLT was 25.3 ± 7.4 minutes, significantly longer than that for the FETE SPLT (18.1 ± 4.0 minutes, P = .031). Perioperatively, 1 anastomosis-related complication occurred in each group, but this did not constitute a statistically significant difference (P = .682). No statistically significant differences were found between the 2 groups in terms of operative time, postoperative hospital stay, operative cost, surgical margins, or number of lymph nodes removed. Postoperative morbidity rates were similar between the groups (4.4% vs 5.8%, P = .676). ConclusionThe overlap SPLT technique is regarded as a safe and feasible method for anastomosis. There were no apparent differences in complications between overlap SPLT and FETE SPLT, but overlap SPLT costed 1 additional stapler cartridge and required a longer duration.

Long‐term quality of life after open and laparoscopic total gastrectomy for stage I gastric cancer: A prospective multi‐institutional study (CCOG1504)

AbstractBackgroundLittle information is available from prospective clinical trials on the influences of surgical approaches on postoperative quality of life (QOL). We aimed to prospectively compare chronological changes in postoperative body weight and QOL between laparoscopic and open total gastrectomy for stage I gastric cancer (GC).MethodsWe conducted a multi‐institutional prospective study (CCOG1504) of patients who undergo laparoscopic or open total gastrectomy. Body weight was measured at the baseline and at the 1st, 2nd, and 3rd postoperative years (POY). QOL using the European Organization for Research and Treatment of Cancer quality of life questionnaire‐C30 (EORTC QLQ‐C30) and the Post‐Gastrectomy Syndrome Assessment Scale‐37 (PGSAS‐37) questionnaires were measured at the baseline and at the 1st, 3rd, 6th, 12th, and 36th postoperative months (POM).ResultsWe enrolled 84 patients from 15 institutions, and finally 43 patients for the laparoscopic group and 16 for the open group were eligible for data analysis. There were no significant differences in body weight change between the two groups. The role functioning score among the EORTC QLQ‐C30 tended to be higher (i.e., better QOL) in the laparoscopic group at POM 1 and 12 after surgery compared to the open group. The dissatisfaction at working score among the PGSAS‐37 at 1 month after surgery was lower (i.e. better QOL) in the laparoscopic group compared to the open group.ConclusionsThe results of CCOG1504 indicated that laparoscopic approach for total gastrectomy was associated with a more favorable dissatisfaction at working score (PGSAS‐37).

Comparative analysis of two digestive tract reconstruction methods in total laparoscopic radical total gastrectomy.

The incidence of gastric cancer has significantly increased in recent years. Surgical resection is the main treatment, but the method of digestive tract reconstruction after gastric cancer surgery remains controversial. In the current study, we sought to explore a reasonable method of digestive tract reconstruction and improve the quality of life and nutritional status of patients after surgery. To this end, we statistically analyzed the clinical results of patients with gastric cancer who underwent jejunal interposition double-tract reconstruction (DTR) and esophageal jejunum Roux-en-Y reconstruction (RY). To explore the application effect of DTR in total laparoscopic radical total gastrectomy (TLTG) and evaluate its safety and efficacy. We collected the relevant data of 77 patients who underwent TLTG at the Fourth Hospital of Hebei Medical University from October 2021 to January 2023. Among them, 35 cases were treated with DTR, and the remaining 42 cases were treated with traditional RY. After 1:1 propensity score matching, the cases were grouped into 31 cases per group, with evenly distributed data. The clinical characteristics and short- and long-term clinical outcomes of the two groups were statistically analyzed. The two groups showed no significant differences in basic data, intraoperative blood loss, number of lymph node dissections, first defecation time after operation, postoperative hospital stay, postoperative complications, and laboratory examination results on the 1st, 3rd, and 5th days after operation. The operation time of the DTR group was longer than that of the RY group [(307.58 ± 65.14) min vs (272.45 ± 62.09) min, P = 0.016], but the first intake of liquid food in the DTR group was shorter than that in the RY group [(4.45 ± 1.18) d vs (6.0 ± 5.18) d, P = 0.028]. The incidence of reflux heartburn (Visick grade) and postoperative gallbladder disease in the DTR group was lower than that in the RY group (P = 0.033 and P = 0.038). Although there was no significant difference in body weight, hemoglobin, prealbumin, and albumin between the two groups at 1,3 and 6 months after surgery, the diet of patients in the DTR group was better than that in the RY group (P = 0.031). The clinical effect of DTR in TLTG is better than that of RY, indicating that it is a more valuable digestive tract reconstruction method in laparoscopic gastric cancer surgery.

The safety, feasibility and oncological outcomes of laparoscopic completion total gastrectomy for remnant gastric cancer: a prospective study with 3-year follow-up (FUGES-004 study).

The efficacy of laparoscopic completion total gastrectomy (LCTG) for remnant gastric cancer (RGC) remains controversial. The primary outcome was postoperative morbidity within 30 days after surgery. Secondary outcomes included 3-year disease-free survival (DFS), 3-year overall survival (OS), and recurrence. Inverse probability treatment weighted (IPTW) was used to balance the baseline between LCTG and OCTG. Final analysis included 46 patients with RGC who underwent LCTG at the FJMUUH between June 2016 and June 2020. The historical control group comprised of 160 patients who underwent open completion total gastrectomy (OCTG) in the six tertiary teaching hospitals from CRGC-01 study. After IPTW, no significant difference was observed between the LCTG and OCTG groups in terms of incidence (LCTG vs. OCTG: 28.0% vs. 35.0%, P=0.379) or severity of complications within 30 days after surgery. Compared with OCTG, LCTG resulted in better short-term outcomes and faster postoperative recovery. However, the textbook outcome rate was comparable between the two groups (45.9% vs. 32.8%, P=0.107). Additionally, the 3-year DFS and 3-year OS of LCTG were comparable to those of OCTG (DFS: log-rank P=0.173; OS: log-rank P=0.319). No significant differences in recurrence type, mean recurrence time, or 3-year cumulative hazard of recurrence were observed between the two groups (all P>0.05). Subgroup analyses and concurrent comparisons demonstrated similar trends. This prospective study suggested that LCTG was non-inferior to OCTG in both short- and long-term outcomes. In experienced centers, LCTG may be considered as a viable treatment option for RGC.

Long-term survival outcomes of robotic total gastrectomy for locally advanced proximal gastric cancer: a prospective study.

Robotic gastrectomy is a safe and feasible approach for gastric cancer (GC); however, its long-term oncological efficacy remains unclear. We evaluated the long-term survival outcomes and recurrence patterns of patients with locally advanced proximal GC who underwent robotic total gastrectomy (RTG). This prospective study (FUGES-014 study) enrolled 48 patients with locally advanced proximal GC who underwent RTG between March 2018 and February 2020 at a tertiary referral teaching hospital. Patients who underwent laparoscopic total gastrectomy (LTG) in the FUGES-002 study were enrolled in a 2:1 ratio to compare the survival outcomes between RTG and LTG. The primary endpoint of the FUGES-014 study was postoperative 30-day morbidity and has been previously reported. Here we reported the results of 3-year disease-free survival (DFS), 3-year overall survival (OS), and recurrence patterns. After propensity score matching, 48 patients in the RTG and 96 patients in the LTG groups were included. The 3-year DFS rates were 77.1% (95% confidence interval [CI] 66.1-89.9%) for the RTG and 68.8% (95% CI 60.1-78.7%) for the LTG groups ( P =0.261). The 3-year OS rates were not significantly different between the groups (85.4% vs. 74.0%, P =0.122). Recurrence occurred in nine patients (18.8%) in the RTG and 27 (28.1%) patients in the LTG groups ( P =0.234). Recurrence patterns and causes of death were similar between the groups ( P >0.05). The oncological outcome of RTG was non-inferior to that of LTG. Thus, RTG might be an alternative surgical treatment for locally advanced proximal GC.

Safe and Accurate Laparoscopic Total Gastrectomy for Remnant Gastric Cancer With Severe Adhesions Using Indocyanine Green Fluorescence Imaging: Guidance in Detection of the Accurate Dissection Layer to Avoid Organ Injury.

Laparoscopic total gastrectomy (LTG) for remnant gastric cancer (RGC) requires advanced techniques due to severe postoperative adhesions and anatomic changes. We performed LTG in 2 patients with RGC using intraoperative indocyanine green (ICG) fluorescence imaging. Both cases previously underwent distal gastrectomy with Billroth-I reconstruction for gastric cancer and were subsequently diagnosed with early-stage gastric cancer of the remnant stomach. Indocyanine green (2.5mg/body) was administered intravenously during surgery. The liver and common bile duct were clearly visualized during surgery using near-infrared fluorescence laparoscopy, and the adhesions between the hepatobiliary organs and remnant stomach were safely dissected. Laparoscopic total gastrectomy was successfully performed without complications, and the postoperative course was uneventful in both cases. Intraoperative real-time ICG fluorescence imaging allows clear visualization of the liver and common bile duct and can be useful in LTG for RGC with severe adhesions.

Safety and Limitations of Laparoscopic Total Gastrectomy for Gastric Cancer: A Comparative Analysis of Short and Long-term Outcomes With Open Surgery.

Laparoscopic gastrectomy is a standard treatment strategy for gastric cancer (GC); however, the clinical impact of laparoscopic total gastrectomy (LTG) on survival outcomes remains unclear. We compared the short- and long-term results of LTG with those of open total gastrectomy (OTG). Patients undergoing total gastrectomy with lymph node dissection for Stage I/II/III GC between 2010 and 2020 were retrospectively analyzed. Patients were classified into those undergoing LTG (n=143, LTG group) and OTG (n=173, OTG group). The primary outcome was relapse-free survival (RFS). The LTG group exhibited a higher prevalence of early T and N factors, with pStage I/II/III distribution skewed toward early-stage in a ratio of 86/24/33 compared to 38/65/69 in the OTG group (p<0.001), respectively. Longer operation time (p<0.001), less blood loss (p<0.001), fewer grade 3-4 complications (p<0.001), and shorter hospital stay (p<0.001) were observed in the LTG than in the OTG group. LTG was associated with survival benefits for patients without indication for adjuvant chemotherapy [5-year RFS rate, 96.3% vs. 73.2%; hazard ratio (HR)=0.24; 95% confidence interval (CI)=0.10-0.56; p<0.001]. Among the eligibility criteria for adjuvant chemotherapy (Stage II/III excluding pT1 and pT3N0), while the LTG group received more frequently doublet-agent administration (56.5% vs. 11%, p<0.001), conversely, the OTG group exhibited slightly better long-term survival rates (5-year RFS rate, 33.9% vs. 50.2%; HR=1.31; 95%CI=0.82-2.10; p=0.251). LTG contributed to favorable short-term outcomes and demonstrated improved long-term outcomes in early-stage GC; however, careful consideration of indications is warranted for advanced GC cases.

Association of adherence to the enhanced recovery after surgery pathway and outcomes after laparoscopic total gastrectomy

ObjectiveThe current study used a composite outcome to investigate whether applying the ERAS protocol would enhance the recovery of patients undergoing laparoscopic total gastrectomy (LTG).ExposuresLaparoscopic total gastrectomy and perioperative interventions were the exposure. An ERAS clinical pathway consisting of 14 items was implemented and assessed. Patients were divided into either ERAS-compliant or non-ERAS-compliant group according the adherence above 9/14 or not.Main outcomes and measuresThe primary study outcome was a composite outcome called ‘optimal postoperative recovery’ with the definition as below: discharge within 6 days with no sever complications and no unplanned re-operation or readmission within 30 days postoperatively. Univariate logistic regression analysis and multivariate logistic regression analysis were used to model optimal postoperative recovery and compliance, adjusting for patient-related and disease-related characteristics.ResultsA total of 252 patients were included in this retrospective study, 129 in the ERAS compliant group and 123 in the non-ERAS-compliant group. Of these, 79.07% of the patients in ERAS compliant group achieved optimal postoperative recovery, whereas 61.79% of patients in non-ERAS-compliant group did (P = 0.0026). The incidence of sever complications was lower in the ERAS-compliant group (1.55% vs. 6.5%, P = 0.0441). No patients in ERAS compliant group had unplanned re-operation, whereas 5.69% (7/123) of patients in non-ERAS-compliant group had (p = 0.006). The median length of the postoperative hospital stay was shorter in the in the ERAS compliant group (5.51 vs. 5.68 days, P = 0.01). Both logistic (OR 2.01, 95% CI 1.21–3.34) and stepwise regression (OR 2.07, 95% CI 1.25–3.41) analysis showed that high overall compliance with the ERAS protocol facilitated optimal recovery in such patients. In bivariate analysis of compliance for patients who had an optimal postoperative recovery, carbohydrate drinks (p = 0.0196), early oral feeding (P = 0.0043), early mobilization (P = 0.0340), and restrictive intravenous fluid administration (P < 0.0001) were significantly associated with optimal postoperative recovery.Conclusions and relevancePatients with higher ERAS compliance (almost 70% of the accomplishment) suffered less severe postoperative complications and were more likely to achieve optimal postoperative recovery.

Hemidouble Stapling Technique versus Ghosting Double Stapling Technique for Esophagojejunostomy after Laparoscopic Total Gastrectomy.

The hemidouble stapler technique (HDST) in laparoscopic intracorporeal esophagojejunostomy has aspects that pose risks to the safety of the anastomosis. We developed a new esophagojejunostomy technique that converts a double-stapled anastomosis to a single-stapled anastomosis in laparoscopic total gastrectomy (LTG). The aim of this study is to compare the results of two techniques. Patients who underwent LTG for gastric cancer in our hospital between October 2016 and May 2022 were included in the study. Patients were retrospectively reviewed in two groups: those who underwent HDST and the ghosting double stapling technique (GDST). Both groups were analysed in terms of demographics, perioperative findings, and postoperative outcomes. The GDST was used in 14 patients. The HDST was used on 16 patients. Two patients in the HDST group whose esophagojejunal anastomosis was not assessed on endoscopic imaging were excluded. The mean total operative times were 292.6 ± 43.7 and 224.3 ± 36.1 min (p < 0.001). The mean times for esophagojejunostomy were 38.6 ± 4.3 and 26.8 ± 6.4 min (p < 0.001). One case of anastomotic stenosis was observed in the HDST group. Anastomotic leakage was not observed in both groups. However, there was no significant difference in overall morbidity between the groups (p > 0.05). Both HDST and GDST can be safely performed in the esophagojejunostomy for LTG.

Catheter-guided anvil insertion for circular stapler esophagojejunal anastomosis: a novel technique in laparoscopic total gastrectomy

ObjectiveThis study evaluates feasibility, safety, and short-term outcomes of employing the catheter-guided stapler anvil insertion technique for esophagojejunal anastomosis using a circular stapler during laparoscopic total gastrectomy (LTG).Materials and methodsFrom September 2021 to April 2023, the catheter-guided stapler anvil insertion technique was employed in 80 patients undergoing laparoscopic total gastrectomy (LTG) for esophagojejunal anastomosis. A modified D2 dissection, according to the en bloc technique, was performed in the patients. Subsequently, a longitudinal incision, approximately 2 cm in length, was made on the anterior wall of the esophagus, about 2 cm above the tumor. The transection line was pre-marked with blue dye along the esophagus's minor axis, and the tail of the anvil was capped with a 10-cm length of catheter (F14 d4.7 mm). The surgeon secures the head of anvil and carefully inserts it into the esophagus, ensuring that only a 5-cm segment of the catheter remains outside the esophagus. A linear cutter was employed to transect and seal the lower end of the esophagus. Subsequently, esophagojejunostomy was performed under laparoscopic guidance using a circular stapler.ResultsAmong patients undergoing esophagojejunal anastomosis with the new technique, postoperative complications included pneumonia or pleural effusion in 14 patients (17.5%), anastomotic stenosis in 3 patients (3.75%), abdominal infection in 2 patients (2.5%), and intestinal obstruction in 1 patient (1.25%). No instances of anastomotic leakage, anastomotic bleeding, or deaths were recorded. All patients experiencing complications improved with conservative treatment, without the need for secondary surgery.ConclusionThe catheter-guided stapler anvil insertion technique is demonstrated to be a safe and effective method for esophagojejunostomy, potentially reducing the occurrence of anastomotic leakage.

Modified reverse puncture technique for esophagojejunostomy during totally laparoscopic total gastrectomy for gastric cancer

Objective: To evaluate the value of implementing a modified reverse puncture procedure for esophagojejunostomy during totally laparoscopic total gastrectomy. Methods: This was a descriptive case series. Relevant clinical data, including the operative procedure, recovery, and pathological findings of 35 patients with gastric cancer who had undergone esophagojejunostomy with a modified reverse puncture technique during totally laparoscopic total gastrectomy in the Department of Gastrointestinal Surgery, Fujian Provincial Hospital, from June 2022 to January 2023, were prospectively collected and retrospectively analyzed. The age of all patients in the group was (64.9±8.0) years old, with 22 males (62.9%) and a body mass index of (23.2±2.4) kg/m2. The tumors were located in the upper and middle parts of the stomach in 24 cases (68.6%) and in the junction of the esophagus and stomach in 11 cases (31.4%). Important technical aspects of the modified reverse puncture procedure are as follows. (1) Site of the esophageal incision: a transverse incision is made across the right lateral wall of the esophagus at the expected site of esophageal disjunction. (2) Technique for inserting an anvil: after threading a silk thread through the tip of anvil, the end of the thread is knotted and fixed as the traction thread, after which an anvil is inserted into the esophagus through the esophageal incision, leaving the end of the traction line exposed. Next, a 60-mm linear cutter is placed through the right midclavicular trocar to straighten the opened esophagus vertically, after which the rod of the anvil is pulled out of a small incision that has been made in the esophagus by pulling the traction thread, thus completing anvil placement. (3) Jejunal binding: the jejunum on the central bar of the stapler is fastened with silk thread to the stump of the jejunum, and then tied to the output loop of the jejunum with a gauze strip. Results: All 35 surgeries were successful, with no mortality or conversion to laparotomy. The operation time, anvil insertion time, and digestive tract reconstruction time were (232.7±34.4), (8.5±1.4), and (40.5±4.8) minutes, respectively. The intraoperative blood loss was 100 (20-250) mL and the incision was (5.3±0.9) cm long. The upper surgical margin was negative in all patients and the mean distance between the upper and tumor margins was (3.5±1.2) cm. The mean number of lymph nodes dissected per patient was 33.9±7.1. The times to initial ambulation, initial passage of flatus , postoperative fluid intake, and length of postoperative hospital stay were (3.2±1.1), (3.7±1.5), (4.6±2.3), and (9.8±3.2) days, respectively. Postoperative complications occurred in five patients: one case of anastomotic leak, two of anastomotic stenosis, one of pulmonary infection, and one of incomplete intestinal obstruction, all of which were successfully managed conservatively. Conclusion: Esophagojejunostomy using a modified reverse puncture technique during totally laparoscopic total gastrectomy is safe and feasible for gastric cancer, requiring only a small incision and achieving higher upper esophageal resection margins and good postoperative recovery, and therefore warrants further implementation.

The "quadrant-sandwich" method in clockwise modular D2 lymph node dissection in laparoscopic total gastrectomy: a retrospective cohort study.

For patients who need laparoscopic radical gastrectomy, lymph node dissection (LND) and optimization of surgical procedures are particularly important. This study introduces the "quadrant-sandwich" method in clockwise modular D2 LND and evaluates the advantages and safety of this method. The clinical data of 108 laparoscopic total gastrectomy patients admitted to the Affiliated Cancer Hospital of Zhengzhou University from January 2019 to January 2022 were retrospectively analyzed. Based on the different LND processes, 55 patients were allocated to the observation group, which underwent clockwise modular LND using the "quadrant-sandwich method", and 53 patients were allocated to the control group, which underwent traditional LND. The effectiveness and safety of the approach in terms of operation time, blood loss, lymph node yield, postoperative recovery and postoperative complications were observed in the two groups. There was no statistical difference between the baseline data of the two groups. In relation to the surgery, the observation group had an operation time of 227.0±48.5 minutes, and intraoperative bleeding of 100.0 mL [inter-quartile range (IQR), 30.0-200.0 mL], while the control group had an operation time of 247±41.5 minutes, and intraoperative bleeding of 180.0 mL (IQR, 130.0-245.0 mL). There were statistically significant differences between the two groups in terms of the operation time and intraoperative bleeding (P=0.001, P=0.020). In relation to the LND, there were no statistically significant differences between the two groups in terms of the total number of lymph nodes in each division, and the number of positive lymph nodes. In relation to the post-operative results, there were no statistically significant differences between the two groups in terms of the post-operative pathological stage, first postoperative oral feeding, post-operative hospitalization time, and post-operative complications. Clockwise modular D2 LND using the "quadrant-sandwich method" is potentially safe and feasible in laparoscopic total gastrectomy. It not only ensures the thoroughness of the LND, but also ensures and efficient and fast surgical process, shortens the operation time, and reduces the amount of intraoperative bleeding.
