Digestive tract reconstruction using isoperistaltic jejunum-later-cut overlap method after totally laparoscopic total gastrectomy for gastric cancer: Short-term outcomes and impact on quality of life

Comparison efficacy and safety of total laparoscopic gastrectomy and laparoscopically assisted total gastrectomy in treatment of gastric cancer

BACKGROUND

The development of laparoscopic technology has provided a new choice for surgery of gastric cancer (GC), but the advantages and disadvantages of laparoscopic total gastrectomy (LTG) and laparoscopic-assisted total gastrectomy (LATG) in treatment effect and safety are still controversial. The purpose of this study is to compare the efficacy and safety of the two methods in the treatment of GC, and to provide a basis for clinical decision-making.

AIM

To compare the efficacy of totally LTG (TLTG) and LATG in the context of radical gastrectomy for GC. Additionally, we investigated the safety and feasibility of the total laparoscopic esophagojejunostomy technique.

METHODS

Literature on comparative studies of the above two surgical methods for GC (TLTG group and LATG group) published before September 2022 were searched in the PubMed, Web of Science, Wanfang Database, CNKI, and other Chinese and English databases. In addition, the following search keywords were used: Gastric cancer, total gastrectomy, total laparoscopy, laparoscopy-assisted, esophagojejunal anastomosis, gastric/stomach cancer, total gastrectomy, totally/completely laparoscopic, laparoscopic assisted/laparoscopy assisted/laparoscopically assisted, and esophagojejunostomy/esophagojejunal anastomosis. Review Manager 5.3 software was used for the meta-analysis after two researchers independently screened the literature, extracted the data, and evaluated the risk of bias in the included studies.

RESULTS

After layer-by-layer screening, 258 pieces of literature were recovered, and 11 of those pieces were eventually included. This resulted in a sample size of 2421 instances, with 1115 cases falling into the TLTG group and 1306 cases into the LATG group. Age or sex differences between the two groups were not statistically significant, according to the meta-analysis, however the average body mass index of the TLTG group was considerably higher than that of the LATG group (P = 0.01). Compared with those in the LATG group, the incision length in the TLTG group was significantly shorter (P < 0.001), the amount of intraoperative blood loss was significantly lower (P = 0.003), the number of lymph nodes removed was significantly greater (P = 0.04), and the time of first postoperative feeding and postoperative hospitalization were also significantly shorter (P = 0.03 and 0.02, respectively). There were no significant differences in tumor size, length of proximal incisal margin, total operation time, anastomotic time, postoperative pain score, postoperative anal exhaust time, postoperative anastomosis-related complications (including anastomotic fistula, anastomotic stenosis, and anastomotic hemorrhage), or overall postoperative complication rate (P > 0.05).

CONCLUSION

TLTG and esophagojejunostomy are safe and feasible. Compared with LATG, TLTG has the advantages of less trauma, less bleeding, easier access to lymph nodes, and faster postoperative recovery, and TLTG is also suitable for obese patients.

Risk Factors of Alcohol Use Disorders Among Inpatients with Schizophrenia: An Institutional-Based Cross-sectional Survey

Objective

This study aimed to elucidate the risk factors associated with alcohol use disorders (AUDs) among inpatients with schizophrenia at a specialized mental hospital in Baoding city, China.

Methods

This cross-sectional survey comprised 301 comorbid patients. Three binary logistic regression models were used to investigate the factors linked to AUDs in patients with schizophrenia. Propensity score matching analysis was conducted to validate inconsistent variables identified by the regression models.

Results

Significant differences were observed between the comorbid and non-comorbid groups concerning sex (P < .001), disposition (P = .049), smoking habits (P < .001), place of residence (P = .010), family relationships (P = .002), family history of mental disorders (P = .008), history of alcoholism (P = .003), onset latency (P = .005), impulsivity (P < .001), suicide or self-injury history (P < .001), and obvious aggressive behavior (P < .001) in univariate analyses. The area under the curve values for the three regression models were 0.83 (P < .001), 0.80 (P < .001), and 0.81 (P < .001), respectively. Binary logistic regression and propensity score matching analyses indicated that introverted disposition, smoking, acute onset, impulsivity, and suicide or self-injury history were independent risk factors associated with AUDs in inpatients with schizophrenia with an odds ratio of > 1.

Conclusion

Introverted disposition, smoking, acute onset, impulsivity, and suicide or self-injury history were independently associated with the AUDs in inpatients with schizophrenia. Future studies should prioritize longitudinal studies to discern the evolving dynamics of potential confounding risk factors.

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

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.

Quality of Life Following the Surgical Management of Gastric Cancer Using Patient-Reported Outcomes: A Systematic Review

Introduction: Surgical management of gastric adenocarcinoma can have a drastic impact on a patient's quality of life (QoL). There is high variability among surgeons' preferences for the type of resection and reconstructive method. Peri-operative and cancer-specific outcomes remain equivalent between the different approaches. Therefore, postoperative quality of life can be viewed as a deciding factor for the surgical approach. The goal of this study was to interrogate patient QoL using patient-reported outcomes (PROs) following gastrectomy for gastric cancer. Methods: This systematic review was registered at Prospero and followed PRISMA guidelines. Medline, Embase, and Scopus were used to perform a literature search on 18 January 2020. A set of selection criteria and the data extraction sheet were predefined. Covidence (Melbourne, Australia) software was used; two reviewers (P.C.V. and E.J.) independently reviewed the articles, and a third resolved conflicts (A.B.F.). Results: The search yielded 1446 studies; 308 articles underwent full-text review. Ultimately, 28 studies were included for qualitative analysis, including 4630 patients. Significant heterogeneity existed between the studies. Geography was predominately East Asian (22/28 articles). While all aspects of quality of life were found to be affected by a gastrectomy, most functional or symptom-specific measures reached baseline by 6-12 months. The most significant ongoing symptoms were reflux, diarrhoea, and nausea/vomiting. Discussion: Generally, patients who undergo a gastrectomy return to baseline QoL by one year, regardless of the type of surgery or reconstruction. A subtotal distal gastrectomy is preferred when proper oncologic margins can be obtained. Additionally, no one form of reconstruction following gastrectomy is statistically preferred over another. However, for subtotal distal gastrectomy, there was a trend toward Roux-en-Y reconstruction as superior to abating reflux.

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

BACKGROUND

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.

MATERIALS AND METHODS

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.

RESULTS

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).

CONCLUSION

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.

Quality of Life in Patients Undergoing Surgery for Upper GI Malignancies

Upper gastrointestinal (GI) conditions vastly affect each individual's physical, social, and emotional status. The decision-making process by the medical personnel about these patients is currently based on a patient's life quality evaluation scale, HRQL scales. By utilizing HRQL scales, a better understanding of the various surgical and non-surgical treatment options, as well as their long-term consequences, can be achieved. In our study, an organ-based approach is used in an attempt to examine and characterized the effect of upper GI surgery on HRQL. Therefore, HRQL scales' function as a prognostic tool is useful, and the need for future research, the creation of valid training programs, and modern guidelines is highlighted.

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

OBJECTIVE

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.

METHODS

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.

RESULTS

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).

CONCLUSIONS

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.

Disturbed passage of jejunal limb near esophageal hiatus after overlapped esophagojejunostomy following laparoscopic total gastrectomy

BACKGROUND

Overlapped esophagojejunostomy (OEJ) is a secure purely laparoscopic reconstruction after laparoscopic total gastrectomy (LTG). However, long-term surgical results have not been documented well.

AIM

In this paper, we report unusual patients who manifested jejunal limb stricture near the esophageal hiatus without anastomotic stenosis during long-term observation after surgery.

METHODS

From April 2009 until May 2020, we retrospectively reviewed 211 patients underwent LTG following by OEJ for gastric carcinoma and took a standard surveillance program. We aimed to characterize a novel complicated disorder observed in these patients to assist treatment and prevention.

RESULTS

Five patients (2.4%) had unusual jejunal limb stricture after LTG and OEJ, occurring at a mean of 10 mo after initial radical LTG. All five patients had disturbed oral intake and marked weight loss, and two had aspiration pneumonia. Various diagnostic modalities and intraoperative findings in each patient revealed an intact anastomosis, bent or tortuous jejunal limb resulting from loose fibrous adhesions on the left crus at the esophageal hiatus and no cancer recurrence. All five patients were successfully treated by reoperation for adhesiolysis, division of the left crus and rearrangement of the jejunal limb.

CONCLUSION

Disturbed passage through the jejunal limb near the hiatus can occur after some types of OEJ following LTG. We speculate that it may result from a short remnant esophagus, excessive mobilization of the jejunal limb that permits bending or tortuosity and adhesions on the left crus at the hiatus. Prevention for this complication is possible during the original LTG procedure.

Assessing optimal Roux-en-Y reconstruction technique after total gastrectomy using the Postgastrectomy Syndrome Assessment Scale-45

BACKGROUND

Following a total gastrectomy, patients suffer the most severe form of postgastrectomy syndrome. This is a significant clinical problem as it reduces quality of life (QOL). Roux-en-Y reconstruction, which is regarded as the gold standard for post-total gastrectomy reconstruction, can be performed using various techniques. Although the technique used could affect postoperative QOL, there are no previous reports regarding the same.

AIM

To investigate the effect of different techniques on postoperative QOL. The data was collected from the registry of the postgastrectomy syndrome assessment study (PGSAS).

METHODS

In the present study, we analyzed 393 total gastrectomy patients from those enrolled in PGSAS. Patients were divided into groups depending on whether antecolic or retrocolic jejunal elevation was performed, whether the Roux limb was “40 cm”, “shorter” (≤ 39 cm), or “longer” (≥ 41 cm), and whether the device used for esophageal and jejunal anastomosis was a circular or linear stapler. Subsequently, we comparatively investigated postoperative QOL of the patients.

RESULTS

Reconstruction route: Esophageal reflux subscale (SS) occurred significantly less frequently in patients who underwent antecolic reconstruction. Roux limb length: “Shorter” Roux limb did not facilitate esophageal reflux SS and somewhat attenuated indigestion SS and abdominal pain SS. Anastomosis technique: In terms of esophagojejunostomy techniques, no differences were observed.

CONCLUSION

The techniques used for total gastrectomy with Roux-en-Y reconstruction significantly affected postoperative symptoms. Our results suggest that elevating the Roux limb, which is not overly long, through an antecolic route may improve patients’ QOL.

Comparison Between Linear Stapler and Circular Stapler After Laparoscopic-Assisted Distal Gastrectomy in Patients With Gastric Cancer

Background and Aim

To evaluate the safety and efficacy of laparoscopy distal gastrectomy using a linear stapler compared with a circular stapler in patients with gastric cancer.

Methods

We retrospectively reviewed 173 patients who underwent laparoscopic distal gastrectomy for gastric cancer at a single center from January 2018 to December 2020. Patients were categorized into the linear stapler group and the circular stapler group. General data, intraoperative and postoperative outcomes, postoperative pathological results, postoperative complications, and postoperative follow-up in the two groups were compared and analyzed.

Results

The operation time (208.76 ± 32.92 vs. 226.69 ± 26.92 min, p &lt; 0.05), anastomosis time (71.87 ± 9.50 vs. 90.56 ± 3.18 min, p &lt; 0.05), time to first flatus (68.60 ± 25.96 vs. 76.16 ± 21.05 h, p &lt; 0.05), time to the first sip of water (3.66 ± 0.61 vs. 4.07 ± 0.77 days, p &lt; 0.05), and time to the first liquid diet (4.43 ± 1.02 vs. 5.03 ± 1.70 days, p &lt; 0.05) were significantly shorter in the linear stapler group. In addition, the highest postoperative body temperature within 3 days (37.4 ± 0.61 vs. 37.7 ± 0.61, p &lt; 0.05) after the operation, white blood cell count (WBC) on the 3rd day (9.07 ± 2.52 vs. 10.01 ± 2.98 × 10∧9/L, p &lt; 0.05), and average gastric tube drainage within 3 days (36.65 ± 24.57 vs. 52.61 ± 37 ml, p &lt; 0.05) were also significantly lower in the linear stapler group.

Conclusions

Both circular and linear staplers are safe and feasible for gastrointestinal reconstruction in laparoscopic distal gastrectomy. In contrast, a linear stapler has advantages over a circular stapler in shortening operation time and accelerating the postoperative recovery of patients.

Health-Related Quality of Life in Locally Advanced Gastric Cancer: A Systematic Review

BACKGROUND

Current treatment strategies have been designed to improve survival in locally advanced gastric cancer patients. Besides its impact on survival, treatment also affects health-related quality of life (HRQOL), but an overview of reported studies is currently lacking. The aim of this systematic review was therefore to determine the short- and long-term impact of chemotherapy, surgery, and (chemo)radiotherapy on HRQOL in locally advanced, non-metastatic gastric cancer patients.

METHODS

A systematic review was performed including studies published between January 2000 and February 2021. We extracted studies published in Medline, Embase, and Scopus databases that assessed HRQOL in patients with locally advanced, non-metastatic gastric cancer treated with curative intent. Studies using non-validated HRQOL questionnaires were excluded. Short-term and long-term HRQOL were defined as HRQOL scores within and beyond 6 months after treatment, respectively.

RESULTS

Initially, we identified 8705 articles (4037 of which were duplicates, i.e., 46%) and ultimately included 10 articles. Most studies reported that short-term HRQOL worsened in the follow-up period from 6 weeks to 3 months after surgery. However, recovery of HRQOL to preoperative levels occurred after 6 months. After completion of chemoradiotherapy, the same pattern was seen with worse HRQOL after treatment and a recovery of HRQOL after 6-12 months.

CONCLUSIONS

In patients with locally advanced, non-metastatic gastric cancer, HRQOL deteriorated during the first 3 months after surgery and chemoradiotherapy. However, the long-term data showed a recovery of HRQOL after 6-12 months. To implement HRQOL in clinical decision making in current clinical practice, more research is needed.

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

BACKGROUND

This study aimed to evaluate the surgical outcome and quality of life (QoL) of totally laparoscopic total gastrectomy (TLTG) compared with laparoscopy-assisted total gastrectomy (LATG) in patients with clinical stage I gastric cancer.

METHODS

From 2012 to 2018, EGC patients who underwent TLTG (n = 223), including the first case with intracorporeal hemi-double stapling, were matched to those who underwent LATG (n = 114) with extracorporeal circular stapling, using 2:1 propensity score matching (PSM). Prospectively collected morbidity was compared between the TLTG and LATG groups in conjunction with the learning curve. The European Organization for Research and Treatment of Cancer (EORTC) QoL questionnaires QLQ-C30, STO22, and OG25 were prospectively surveyed during postoperative 1 year for patient subgroups.

RESULTS

After PSM, grade I pulmonary complication rate was lower in the TLTG group (n = 213) than in the LATG group (n = 111) (0.5% vs. 5.4%, P = 0.007). Other complications were not different between the groups. The learning curve of TLTG was overcome at the 26th case in terms of the comprehensive complication index. The TLTG group after learning curve showed lower grade I pulmonary complication rate than the matched LATG group (0.5% vs. 4.7%, P = 0.024). Regarding postoperative QoL, the TLTG group (n = 63) revealed less dysphagia (P = 0.028), pain (P = 0.028), eating restriction (P = 0.006), eating (P = 0.004), odynophagia (P = 0.023) than the LATG group (n = 21). Multivariate analyses for each QoL item demonstrated that TLTG was the only common independent factor for better QoL.

CONCLUSIONS

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

Impact of Esophagojejunal Reconstruction without Division of the Mesentery for Total Laparoscopic Total Gastrectomy

Purpose

This study aimed to compare the surgical outcomes of total laparoscopic total gastrectomy without mesentery division (LTG without MD) and conventional total laparoscopic total gastrectomy (CLTG), as well as evaluate the appropriate method for esophagojejunostomy (EJ) reconstruction after total laparoscopic total gastrectomy (TLTG).

Materials and Methods

We retrospectively analyzed data from 301 consecutive patients who underwent TLTG for upper or middle third gastric cancer between January 2016 and May 2019. After propensity score matching, 95 patients who underwent LTG without MD and 95 who underwent CLTG were assessed. Data on clinical characteristics and surgical outcomes, including operation time, length of postoperative hospital stay, pathological findings, and postoperative complications were analyzed.

Results

The LTG without MD group showed a shorter time to first flatus (3.26±0.80 vs. 3.62±0.81 days, P=0.003) and a shorter time to soft diet (2.80±2.09 vs. 3.52±2.20 days, P=0.002). The total EJ-related complications in the LTG without MD group were comparable to those in the CLTG group (9.47% vs. 3.16%, P=0.083). EJ-related leakage (6.32% vs. 3.16%, P=0.317) and EJ-related stricture (3.16% vs. 1.05%, P=0.317) rates were not significantly different between the LTG without MD and CLTG groups. No significant differences were found between the two groups in terms of other early surgical outcomes such as early complications, late complications, hospital stay, and readmission rate.

Conclusions

LTG without MD is a safe surgical treatment for upper or middle third gastric cancer. LTG without MD may be an alternative procedure for EJ anastomosis during TLTG.

Esophagus two-step-cut overlap method in esophagojejunostomy after laparoscopic gastrectomy

PURPOSE

Esophagojejunostomy is a challenging step in laparoscopic gastrectomy. Although the overlap method is a safe and feasible approach for esophagojejunostomy, it has several technical limitations. We developed novel modifications for the overlap method to overcome these disadvantages.

METHODS

Forty-eight consecutive gastric cancer patients underwent totally laparoscopic total gastrectomy or laparoscopic proximal gastrectomy with double-tract reconstruction at our institution from January 2019 to April 2020 using the overlap method with the following modifications. The esophagus was initially rotated by 90° counterclockwise, followed by transection of two-thirds of the esophageal diameter. The unstapled esophagus was then transected with a harmonic ultrasonic scalpel to enable esophagostomy at the posterior side of the esophagus. A side-to-side esophagojejunostomy was then formed at the posterior side of the esophagus using an endoscopic linear stapler through the right lower trocar. The common entry hole was closed via hand sewing method using V-Loc suture. This procedure was termed "esophagus two-step-cut overlap method."

RESULTS

Only one patient suffered from esophagojejunal anastomotic leakage but subsequently recovered after conservative treatment. Patients did not experience anastomotic bleeding or stricture.

CONCLUSION

Our modified overlap method provides satisfactory surgical outcomes and overcomes several technical limitations, such as entering the false lumen of the esophagus, unnecessary pollution caused by nasogastric tube, and unintended left crus stapling during anastomosis.

Efficacy of totally laparoscopic compared with laparoscopic-assisted total gastrectomy for gastric cancer: A meta-analysis

BACKGROUND

Laparoscopic radical gastrectomy is currently the most common surgical approach for gastric cancer. The main difference between totally laparoscopic total gastrectomy (TLTG) and laparoscopic-assisted total gastrectomy (LATG) is the route of digestive tract reconstruction. However, TLTG is currently not widespread as the safety and feasibility of intracorporeal esophagojejunostomy is uncertain.

AIM

To compare the short-term efficacy of TLTG and LATG for radical gastrectomy of gastric cancer, and to determine the safety and feasibility of intracorporeal esophagojejunostomy.

METHODS

PubMed, EMBASE, and Web of Science databases were searched for all relevant articles regarding TLTG vs LATG for gastric cancer published up to October 1, 2019. Inclusion and exclusion criteria were established. All the basic conditions of patients and important clinical data related to surgery were extracted, and a meta-analysis was performed with RevMan 5.3 software.

RESULTS

Eight studies involving a total of 1883 cases (869 cases in the TLTG group and 1014 cases in the LATG group) were included. Compared with the LATG group, reduced intraoperative blood loss (weighted mean difference = -35.37, 95%CI: -61.69 - -9.06, P = 0.008) and a larger number of retrieved lymph nodes (weighted mean difference = 3.11, 95%CI: -2.60 - 12.00, P = 0.01) were found in the TLTG group. There were no significant differences in operating time, anastomotic time, tumor size, proximal resection margin length, postoperative pain score, time to first flatus, time to first oral intake, postoperative hospital stay, postoperative anastomosis-related complication rate and overall complication rate between the two groups (P > 0.05).

CONCLUSION

Intracorporeal esophagojejunostomy is safe and feasible. TLTG has the advantages of being minimally invasive, reduced intraoperative blood loss and easier access to lymph nodes compared with LATG. Totally laparoscopic gastrectomy is likely to be the surgical trend for gastric cancer in the future.

Comparison of the short-term outcomes between totally laparoscopic total gastrectomy and laparoscopic-assisted total gastrectomy for gastric cancer: a meta-analysis

BACKGROUND

Totally laparoscopic total gastrectomy (TLTG) and laparoscopic-assisted total gastrectomy (LATG) are two common surgical approaches for upper and middle gastric cancer. Which surgical approach offers more advantages is still controversial due to a lack of evidence from randomized controlled trials (RCTs). This meta-analysis was conducted to compare the short-term outcomes between the two surgical approaches.

METHODS

A systematic literature search was performed to evaluate short-term outcomes between TLTG and LATG, including overall postoperative complications, anastomosis-related complications, time for anastomosis, operation time, intraoperative blood loss, harvested lymph nodes, proximal margin, distal margin, time to first flatus, time to first diet, and postoperative hospital stay. Short-term outcomes were pooled and compared by meta-analysis using RevMan 5.3. Mean differences (MDs) or risk ratios (RRs) were calculated with 95% confidence intervals (CIs). P < .05 was considered statistically significant.

RESULTS

A total of 9 cohort studies fulfilled the selection criteria. The total sample included 1671 cases. The meta-analysis showed no significant difference between the two surgical approaches in overall postoperative complications (RR = 1.02, 95% CI = 0.82 to 1.26, P = .87),anastomosis-related complications (RR = 0.64, 95%CI = 0.39 to 1.03, P = .06),time for anastomosis (MD = -5.13, 95% CI = -10.54 to 0.27, P = .06),operation time (MD = -10.68, 95% CI = -23.62 to 2.26, P = .11), intraoperative blood loss (MD = -25.58, 95% CI = -61.71 to 10.54, P = .17), harvested lymph nodes (MD = 1.61, 95% CI = -2.09 to 5.31, P = .39), proximal margin (MD = -0.37, 95% CI = -0.78 to 0.05, P = .09), distal margin (MD = 0.79, 95% CI = -0.57 to 2.14, P = .25), time to first flatus (MD = 0.01, 95% CI = -0.13 to 0.15, P = .87), time to first diet (MD = -0.22, 95% CI = -0.45 to 0.02, P = .07), and postoperative hospital stay (MD = -0.51, 95% CI = -1.10 to 0.07, P = .09).

CONCLUSIONS

TLTG is a safe and feasible surgical approach for upper and middle gastric cancer, with short-term outcomes that are similar to LATG. Nevertheless, high-quality, large-sample and multicenter RCTs are still required to further verify our conclusions.

Digestive tract reconstruction options after laparoscopic gastrectomy for gastric cancer

In addition to the popularity of laparoscopic gastrectomy (LG), many reconstructive procedures after LG have been reported. Surgical resection and lymphatic dissection determine long-term survival; however, the election of a reconstruction procedure determines the postoperative quality of life for patients with gastric cancer (GC). Presently, no consensus exists regarding the optimal reconstructive procedure. In this review, the current state of digestive tract reconstruction after LG is reviewed. According to the determining influence of the tumor site on the procedures of surgical resection and reconstruction, we divide these reconstruction procedures into three categories consistent with the resection procedures. We focus on the technical tips of every reconstruction procedure and examine the surgical outcomes (length of surgery and blood loss) and postoperative complications (anastomotic leakage and stricture) to facilitate gastrointestinal surgeons to understand the merits and demerits of every reconstruction procedure.

Reverse puncture device technique: an innovation of esophagojejunostomy in radical laparoscopic total gastrectomy

Aim: To evaluate the feasibility, safety, short- and long-term efficacy of a reverse puncture device (RPD) technique for esophagojejunostomy in laparoscopic-assisted total gastrectomy. Patients & methods: This retrospective study analyzed outcome data of 104 patients in propensity score matching whom were divided into the RPD and the purse-string suture technique group. Results: The RPD group had a shorter anvil placement time, shorter operative time, longer resected esophageal length, shorter incision length, shorter postoperative drainage time, shorter postoperative hospital stay and anastomotic complications than the purse-string suture technique group (p < 0.05). Multivariate analysis showed that BMI (odds ratio: 6.285, 1.446-27.322) and anvil placement time (odds ratio: 5.645, 1.089-29.321) were independent risk factors for anastomotic complications (p < 0.05). Conclusion: Laparoscopic-assisted total gastrectomy using an RPD technique is feasible, safe and effective.

Comparison of totally laparoscopic total gastrectomy and laparoscopic-assisted total gastrectomy: A systematic review and meta-analysis

BACKGROUND

Laparoscopic-assisted total gastrectomy (LATG) has been extensively employed for the removal of gastric tumors, although it has several limitations. Totally laparoscopic total gastrectomy (TLTG) is a new technique that has rapidly been gaining popularity, and may help overcome the limitations of LATG; however, its safety and therapeutic effect remain controversial. In the present study, we aimed to assess the safety and efficacy of TLTG, and compare the short-term outcomes of TLTG and LATG.

METHODS

We searched for studies comparing TLTG and LATG published up to April 2018 from databases such as PubMed and Embase. The study results, including time of surgery, blood loss, anastomosis time, retrieved lymphatic nodes, proximal and distal resection edges, incision length, time to first fluid and soft diet, hospitalization duration, time to first flatus, and postsurgical and anastomotic complications, were compared between the procedures.

RESULTS

A total of 10 studies were included. TLTG led to reduced intraoperative blood loss (P < 0.01), greater number of retrieved lymphatic nodes (P < 0.01), decreased hospitalization duration (P < 0.01), reduced incision length (P = 0.05), and shorter time to first fluid diet (P < 0.05), as compared to LATG. The surgery and anastomosis times, time to first soft diet, resection edge, time to first flatus, overall postsurgical complications, and anastomosis-related complications were similar between TLTG and LATG (P > 0.05).

CONCLUSIONS

TLTG is a safe procedure that yields better cosmesis lower invasiveness, and faster recovery as compared to LATG.
