RESUMEN

BACKGROUND: This study aims to investigate the feasibility and value of modular splenic hilar lymphadenectomy (MSHL) in LTG for advanced PGC located at the greater curvature. STUDY DESIGN: A retrospective-controlled research included 54 patients diagnosed with advanced PGC located at the greater curvature who underwent LTG combined with spleen-preserving hilar lymphadenectomy between January 2020 and December 2022 at the same treatment center. A total of 20 patients underwent classic splenic hilar lymphadenectomy (CSHL) using a medial approach (classic group), while 34 patients underwent MSHL (modular group). We summarized the technical points, caveats, and critical steps of the MSHL technique and observed and compared clinical indexes between the two groups. RESULTS: All operations were successful without conversion to laparotomy. The mean operation time, mean splenic hilar lymph node dissection (LND) time, median intraoperative blood loss, and blood loss from splenic hilar LND were all significantly lower in the modular group than in the classic group (p < 0.05). The amount of NO.10 lymph nodes (LNs) was significantly higher in the modular group than in the classic group (p < 0.05). In the classic group, one patient experienced intraoperative splenic vein injury, and one experienced spleen laceration, whereas no intraoperative complications occurred in the modular group. The median postoperative feeding time, exhaust time, defecation time, and postoperative stay were all significantly lower in the modular group compared to the classic group (p < 0.05). In the modular group, one patient experienced Clavien-Dindo I complication and one Clavien-Dindo II complication, while in the classic group, one patient experienced Clavien-Dindo II complication and one Clavien-Dindo IIIa complication. There were no patient was re-hospitalized within 30 days after surgery. CONCLUSION: The modular splenic hilar LND technique can simplify complicated surgical procedures in SPSHL and reduce the risk of intraoperative bleeding and collateral damage.

RESUMEN

Background: The association between postoperative complications and long-term survival after laparoscopic gastrectomy (LG) for gastric cancer (GC) remains uncertain. This study aimed to determine the incidence and risk factors of postoperative complications and evaluate their impact on survival outcomes in patients undergoing LG. Methods: A retrospective study was conducted on 621 patients who underwent LG for gastric adenocarcinoma between March 2015 and December 2021. Postoperative complications were classified according to the Clavien-Dindo classification, with major complications defined as Grade III or higher. Logistic regression models with stepwise backward procedure were used to identify risk factors for complications. To assess the impact of postoperative complications on survival, uni- and multi-variable Cox proportional hazard models were used for overall survival (OS) and disease-free survival (DFS). Results: Overall rate of postoperative complications was 17.6% (109 patients); 33 patients (5.3%) had major complications. Independent risk factors for major complications were Charlson comorbidities index (OR [95% CI], 1.87 [1.09-3.12], p-value = 0.018 for each one score increase), and type of anastomosis (OR [95% CI], 0.28 [0.09-0.91], p-value = 0.029 when comparing Billroth II with Billroth I). Multivariable analysis identified major complications as an independent prognostic factor to reduce OS (HR [95% CI], 2.32 [1.02-5.30], p-value = 0.045) and DFS (HR [95% CI], 2.63 [1.37-5.06], p-value = 0.004). Other prognostic factors for decreased survival outcomes were tumor size, presence of invasive lymph nodes, and T4a stage. Conclusions: Major complications rate of LG for GC was approximately 5.3%. Charlson comorbidities index and type of anastomosis were identified as risk factors for major postoperative complications. Major complications were demonstrated to pose adverse impact on survival outcomes.

RESUMEN

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: 257 min vs. 231 min, 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.

RESUMEN

Background: Laparoscopic 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. Methods: We 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. Results: A 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<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. Conclusion: We 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.

RESUMEN

BACKGROUND: This 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. METHODS: From 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. RESULTS: The 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). CONCLUSION: The 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.

RESUMEN

While the importance of conversion surgery has increased with the development of systemic chemotherapy for gastric cancer (GC), reports of conversion surgery for patients with GC with distant metastasis and tumor thrombus are extremely scarce, and a definitive surgical strategy has yet to be established. Herein, we report a 67-year-old man with left abdominal pain referred to our hospital following a diagnosis of unresectable GC. Esophagogastroduodenoscopy and contrast-enhanced abdominal computed tomography (CT) revealed advanced GC with splenic metastasis. A splenic vein tumor thrombus (SVTT) and a continuous thrombus to the main trunk of the portal vein were detected. The patient was treated with anticoagulation therapy and systemic chemotherapy comprising S-1 and oxaliplatin. One year following chemotherapy initiation, a CT scan revealed progressive disease (PD); therefore, the chemotherapy regimen was switched to ramucirumab with paclitaxel. After 10 courses of chemotherapy resulting in primary tumor and SVTT shrinkage, the patient underwent laparoscopic total gastrectomy (LTG) and distal pancreaticosplenectomy (DPS). He was discharged without complications and remained alive 6 months postoperatively without recurrence. In summary, the wait-and-see approach was effective in a patient with GC with splenic metastasis and SVTT, ultimately leading to an R0 resection performed via LTG and DPS.

RESUMEN

Laparoscopic total gastrectomy results in more internal hernias than open surgery. However, there are few reports of incarcerated hiatal hernia after laparoscopic total gastrectomy. Here, we report a case of a 79-year-old male who underwent urgent surgical intervention for a strangulated intestinal obstruction due to an incarcerated hernia through the esophageal hiatus following laparoscopic total gastrectomy. In this case, an esophageal hiatal hernia was present before gastrectomy, but was not repaired. Additionally, the patient experienced significant weight loss after gastrectomy. Preoperative hiatal hernia and marked postoperative weight loss may pose risks.

RESUMEN

OBJECTIVE: This 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 METHODS: From 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. RESULTS: Among 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. CONCLUSION: The catheter-guided stapler anvil insertion technique is demonstrated to be a safe and effective method for esophagojejunostomy, potentially reducing the occurrence of anastomotic leakage.

RESUMEN

OBJECTIVE: To investigate the clinical efficacy and prognostic implication of hand-sewn anastomosis in laparoscopic total gastrectomy (LTG). METHODS: Retrospective analysis is adopted to the clinicopathologic data of 112 patients with gastric cancer (GC) who went through LTG in the Department of General Surgery, the Second Affiliated Hospital of Anhui Medical University between October 2020 and October 2022. Among them, 60 individuals receiving medical care were split into the hand-sewn anastomosis group (Group H, N = 60); while, 52 individuals were split into the circular stapler anastomosis group (Group C, N = 52) The clinical efficacy and prognostic conditions of hand-sewn anastomosis are compared with those of circular stapler anastomosis in the application of LTG. RESULTS: The analysis results indicated that no notable difference was observed in intraoperative bleeding volume, time to first flatus (TFF), postoperative hospitalization duration and postoperative complications among the two groups (P > 0.05). Group H had shorter esophagojejunal anastomosis duration (20.0 min vs. 35.0 min) and surgery duration (252.6 ± 19.4 min vs. 265.9 ± 19.8 min), smaller incisions (5.0 cm vs. 10.5 cm), and lower hospitalization costs (58415.0 CNY vs. 63382.5 CNY) compared to Group C (P < 0.05). CONCLUSION: The clinical efficacy and the postoperative complications of hand-sewn esophagojejunostomy are basically equivalent in comparison to the circular stapler anastomosis in the application of LTG. Its advantage lies in shorter esophagojejunal anastomosis duration, shorter surgery duration, smaller incisions, lower hospitalization costs and wider adaptability of the location of the tumor.

RESUMEN

BACKGROUND/AIM: 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 AND METHODS: 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). RESULTS: 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). CONCLUSION: 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.

RESUMEN

OBJECTIVE: The current study used a composite outcome to investigate whether applying the ERAS protocol would enhance the recovery of patients undergoing laparoscopic total gastrectomy (LTG). EXPOSURES: Laparoscopic 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 MEASURES: The 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. RESULTS: A 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 RELEVANCE: Patients with higher ERAS compliance (almost 70% of the accomplishment) suffered less severe postoperative complications and were more likely to achieve optimal postoperative recovery.

RESUMEN

Background: Laparoscopic gastrectomy for gastric cancer has become widespread as minimally invasive surgical treatment, but use of laparoscopic total gastrectomy (LTG) remains limited because of the technical difficulty and complexity of lymphadenectomy at the splenic hilum. Surgical techniques and initial experiences with the surgical approach to the upper side of the gastrosplenic ligament during LTG are introduced. Materials and Methods: Between January 2019 and December 2022, 57 patients with proximal gastric cancer underwent LTG using this approach. Results: Regarding the extent of lymphadenectomy, D1+, D2, spleen-preserving D2 + 10, and D2 + 10 with splenectomy were performed in 31, 18, 4, and 4 patients, respectively. Operative time was 341 (192-724) minutes, and estimated blood loss was 30 (0-515) g. There were no conversions to laparotomy and no postoperative complications of Clavien-Dindo grade ≥III. Conclusions: The present procedure is safe and feasible and provides an excellent operative view at the splenic hilum, making it easier to determine exactly the extent of lymphadenectomy in accordance with cancer progression.

RESUMEN

BACKGROUND: Laparoscopic radical gastrectomy is widely used, and perioperative complications have become a highly concerned issue. AIM: To develop a predictive model for complications in laparoscopic radical gastrectomy for gastric cancer to better predict the likelihood of complications in gastric cancer patients within 30 days after surgery, guide perioperative treatment strategies for gastric cancer patients, and prevent serious complications. METHODS: In total, 998 patients who underwent laparoscopic radical gastrectomy for gastric cancer at 16 Chinese medical centers were included in the training group for the complication model, and 398 patients were included in the validation group. The clinicopathological data and 30-d postoperative complications of gastric cancer patients were collected. Three machine learning methods, lasso regression, random forest, and artificial neural networks, were used to construct postoperative complication prediction models for laparoscopic distal gastrectomy and laparoscopic total gastrectomy, and their prediction efficacy and accuracy were evaluated. RESULTS: The constructed complication model, particularly the random forest model, could better predict serious complications in gastric cancer patients undergoing laparoscopic radical gastrectomy. It exhibited stable performance in external validation and is worthy of further promotion in more centers. CONCLUSION: Using the risk factors identified in multicenter datasets, highly sensitive risk prediction models for complications following laparoscopic radical gastrectomy were established. We hope to facilitate the diagnosis and treatment of preoperative and postoperative decision-making by using these models.

RESUMEN

Background: Intracorporeal esophagojejunostomy (EJ) in the context of laparoscopic total gastrectomy remains a complex and technically demanding procedure. We have previously introduced a novel method of intracorporeal circular stapled EJ utilizing a conventional purse-string suture instrument. Since May 2018, we have refined this technique, and the aim of this study was to assess its safety and efficacy. Methods: Between May 2018 and June 2022, we enrolled 92 patients who underwent laparoscopic total gastrectomy with the modified intracorporeal reconstruction method. In addition, between March 2014 and June 2022, we enrolled 121 patients who underwent the procedure with the extracorporeal reconstruction method. We retrospectively collected and compared the clinical data of these 2 patient cohorts. Results: Intracorporeal reconstruction group experienced lower postoperative pain scores (2.7 ± 1.3 versus 4.5 ± 1.4, P = .032), reduced administration of analgesics (3.1 ± 2.2 versus 5.0 ± 3.5, P = .041), and shorter postoperative hospital stays (4.9 ± 2.3 versus 6.3 ± 3.5, P = .045) compared with the extracorporeal reconstruction group. In addition, anastomotic time and postoperative pain score were not increased in the overweight patients in the intracorporeal reconstruction group. Anastomotic leakage occurred in 2 (2.2%) patients in the intracorporeal reconstruction group and 4 (3.3%) patients in the extracorporeal reconstruction group. Anastomotic stricture occurred in 1 (1.1% and 0.8%) patient in each group. There was no significant difference in the overall postoperative complication rate between the 2 groups. Conclusions: The modified intracorporeal purse-string stapling technique for EJ during laparoscopic total gastrectomy is a safe and viable option, exhibiting less invasiveness and comparable outcomes to the extracorporeal reconstruction method, especially suitable for obese patients.

RESUMEN

Background: 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). Patients and Methods: 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. Results: 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. Conclusions: 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.

RESUMEN

BACKGROUND: Different techniques have been described for esophagojejunostomy (EJ) during laparoscopic total gastrectomy (LTG) for gastric cancer. Linear stapled techniques include overlap (OL) and functional end-to-end anastomosis (FEEA) while single staple technique (SST), hemi-double staple technique (HDST), and OrVil® are circular stapled approaches. Nowadays, the choice among techniques for EJ depends on operating surgeon personal preference. PURPOSE: To compare short-term outcomes of different EJ techniques during LTG. METHODS: Systematic review and network meta-analysis. OL, FEEA, SST, HDST, and OrVil® were compared. Primary outcomes were anastomotic leak (AL) and stenosis (AS). Risk ratio (RR) and weighted mean difference (WMD) were used as pooled effect size measures, whereas 95% credible intervals (CrI) were used to measure relative inference. RESULTS: Overall, 3177 patients (20 studies) were included. The technique for EJ was SST (n = 1026; 32.9%), OL (n = 826; 26.5%), FEEA (n = 752; 24.1%), OrVil® (n = 317; 10.1%), and HDST (n = 196; 6.4%). AL was comparable for OL vs. FEEA (RR = 0.82; 95% CrI 0.47-1.49), OL vs. SST (RR = 0.55; 95% CrI 0.27-1.21), OL vs. OrVil® (RR = 0.54; 95% CrI 0.32-1.22), and OL vs. HDST (RR = 0.65; 95% CrI 0.28-1.63). Similarly, AS was similar for OL vs. FEEA (RR = 0.46; 95% CrI 0.18-1.28), OL vs. SST (RR = 0.89; 95% CrI 0.39-2.15), OL vs. OrVil® (RR = 0.36; 95% CrI 0.14-1.02), and OL vs. HDST (RR = 0.61; 95% CrI 0.31-1.21). Anastomotic bleeding, time to soft diet resumption, pulmonary complications, hospital length of stay, and mortality were comparable while operative time was reduced for FEEA. CONCLUSIONS: This network meta-analysis shows similar postoperative AL and AS risk when comparing OL, FEEA, SST, HDST, and OrVil® techniques. Similarly, no differences were found for anastomotic bleeding, operative time, soft diet resumption, pulmonary complications, hospital length of stay and 30-day mortality.

RESUMEN

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.

RESUMEN

Background: In laparoscopic total gastrectomy with overlap esophagojejunostomy (EJS), esophageal 'false track' is easily formed during EJS. In this study, a linear cutter/stapler guiding device (LCSGD) was used in EJS, so that the linear cutting stapler can complete the technical action with high speed and high efficiency in a narrow space, while avoiding the formation of 'false passage', optimizing the quality of common opening and shortening the anastomosis time. The LCSGD is safe and feasible in laparoscopic total gastrectomy overlap EJS, and the clinical effect is satisfactory. Methods: A retrospective, descriptive design was adopted. The clinical data of 10 gastric cancer patients admitted to the Third Department of Surgery of the Fourth Hospital of Hebei Medical University from July 2021 to November 2021 were collected. The cohort comprised 8 males and 2 females aged 50-75 years. Results: (I) The intra-operative conditions: 10 patients received LCSGD-guided overlap EJS after radical laparoscopic total gastrectomy. Both D2 lymphadenectomy and R0 resection were achieved in these patients. No combined multiple organ resection was performed. There was neither conversion to an open thoracic or abdominal procedure nor conversion to other EJS approaches. The average time from the entry of the LCSGD into the abdominal cavity to the completion of the firing of the stapler was 1.8±0.4 minutes, the average time for manual suturing of the EJS common opening was 14.4±2.1 minutes (mean: 18±2 stitches), and the average operative time was 255±52 minutes. (II) The postoperative outcomes: the time to the first ambulation was 1.9±1.4 days, the average time to the first postoperative exhaust/defecation was 3.5±1.3 days, the average time to a semi-liquid diet was 3.6±0.7 days, and the average postoperative hospital stay was 10.4±4.1 days. All patients were smoothly discharged, without any secondary surgery, bleeding, anastomotic fistula, or duodenal stump fistula. (III) Follow-up: The telephone follow-up lasted 9-12 months. No eating disorders or anastomotic stenosis was reported. One patient experienced Visick grade II heartburn, and the condition of the remaining 9 patients was Visick grade I. Conclusions: Application of the LCSGD in overlap EJS after laparoscopic total gastrectomy is safe and feasible, with satisfactory clinical effectiveness.

Aim: To compare the survival outcomes of laparoscopic total gastrectomy (LTG) with those of open total gastrectomy (OTG) in gastric cancer. Methods: Using an in-house database, this single-center study reviewed clinical data for patients who underwent surgery for gastric adenocarcinoma in 2008-2018. The patients were divided into an LTG group and an OTG group. Results: Data for 638 patients were screened. After exclusions, 580 patients (LTG, n = 212; OTG, n = 368) were enrolled. Noting that the OTG group included more advanced tumors, 1:1 propensity score matching was implemented to reduce any selection bias, leaving 326 patients (LTG, n = 163; OTG, n = 163; pStage I/II/III = 147/87/92) for further analysis. The operation time was longer and blood loss was less in the LTG group. The postoperative hospital stay was shorter in the LTG group than in the OTG group (9 d vs 10 d；P = .040). There was no significant difference in the incidence of grade III or worse postoperative complications (8.9% vs 11.0%). Five-year overall survival was better in the LTG group (84.9% vs 73.5%; P = .0010, log-rank test), but there was no significant difference in overall survival according to pStage (I, 93.0% vs 89.0%; II, 85.8% vs 77.5%; III, 64.1% vs 52.5%). There was a similar trend in relapse-free survival. Distribution of recurrence sites was comparable. Conclusion: LTG may provide survival outcomes similar to those of OTG when performed by an experienced surgical team. Further evidence is required for final conclusions, especially regarding its efficacy for stage II/III.

RESUMEN

This study aimed to investigate the incidence and prognosis of postoperative complications after laparoscopic total gastrectomy (LTG) for gastric cancer (GC). We retrospectively enrolled 411 patients who underwent curative LTG for GC at seven institutions between January 2004 and December 2018. The patients were divided into two groups, complication group (CG) and non-complication group (non-CG), depending on the presence of serious postoperative complications (Clavien-Dindo grade III [≥ CD IIIa] or higher complications). Short-term outcomes and prognoses were compared between two groups. Serious postoperative complications occurred in 65 (15.8%) patients. No significant difference was observed between the two groups in the median operative time, intraoperative blood loss, number of lymph nodes harvested, or pathological stage; however, the 5-year overall survival (OS; CG 66.4% vs. non-CG 76.8%; p = 0.001), disease-specific survival (DSS; CG 70.1% vs. non-CG 76.2%; p = 0.011), and disease-free survival (CG 70.9% vs. non-CG 80.9%; p = 0.001) were significantly different. The Cox multivariate analysis identified the serious postoperative complications as independent risk factors for 5-year OS (HR 2.143, 95% CI 1.165-3.944, p = 0.014) and DSS (HR 2.467, 95% CI 1.223-4.975, p = 0.011). A significant difference was detected in the median days until postoperative recurrence (CG 223 days vs. non-CG 469 days; p = 0.017) between the two groups. Serious postoperative complications after LTG negatively affected the GC prognosis. Efforts to decrease incidences of serious complications should be made that may help in better prognosis in patients with GC after LTG.
