New-style laparoscopic and endoscopic cooperative surgery for gastric stromal tumors

AIM: To evaluate the feasibility and safety of a new style of laparoscopic and endoscopic cooperative surgery (LECS), an improved method of laparoscopic intragastric surgery (LIGS) for the treatment of gastric stromal tumors (GSTs). METHODS: Six patients were treated with the newstyle LECS. Surgery was performed according to the following procedures: (1) Exposing and confirming the location of the tumor with gastroscopy; (2) A laparoscopy light was placed in the cavity using the trocar at the navel, and the other two trocars penetrated both the abdominal and stomach walls; (3) With gastroscopy monitoring, the operation was carried out in the gastric lumen using laparoscopic instruments and the tumor was resected; and (4) The tumor tissue was removed orally using a gastroscopy basket, and puncture holes and perforations were sutured using titanium clips. RESULTS: Tumor size ranged from 2.0 to 4.5 cm (average 3.50 ± 0.84 cm). The operative time ranged from 60 to 130 min (average 83.33 ± 26.58 min). Blood loss was less than 20 mL and hospital stay ranged from 6 to 8 d (average 6.67 ± 0.82 d). The patients were allowed out of bed 12 h later. A stomach tube was inserted for 72 h after surgery, and a liquid diet was then taken. All cases had single tumors which were completely resected using the new-style LECS. No postoperative complications occurred. Pathology of all resected specimens showed GST: no cases of implantation or metastasis were found.CONCLUSION: New-style LECS for GSTs is a quick, optimized, fast recovery, safe and effective therapy.     

Endoscopic full-thickness resection and laparoscopic surgery for treatment of gastric stromal tumors

AIM: To assess the effectiveness of endoscopic full-thickness resection (EFR) and laparoscopic surgery in the treatment of gastric stromal tumors arising from the muscularis propria.METHODS: Out of 62 gastric stromal tumors arising from the muscularis propria, each > 1.5 cm in diameter, 32 were removed by EFR, and 30 were removed by laparoscopic surgery. The tumor expression of CD34, CD117, Dog-1, S-100, and SMA was assessed immunohistochemically. The operative time, complete resection rate, length of hospital stay, incidence of complications, and recurrence rate were compared between the two groups. Continuous data were compared using independent samples t-tests, and categorical data were compared using χ² tests.RESULTS: The 32 gastric stromal tumors treated by EFR and the 30 treated by laparoscopic surgery showed similar operative time [20-155 min (mean, 78.5 ± 30.1 min) vs 50-120 min (mean, 80.9 ± 46.7 min), P > 0.05], complete resection rate (100% vs 93.3%, P > 0.05), and length of hospital stay [4-10 d (mean, 5.9 ± 1.4 d) vs 4-19 d (mean, 8.9 ± 3.2 d), P >0.05]. None of the patients treated by EFR experienced complications, whereas two patients treated by laparoscopy required a conversion to laparotomy, and one patient had postoperative gastroparesis. No recurrences were observed in either group. Immunohistochemical staining showed that of the 62 gastric stromal tumors diagnosed by gastroscopy and endoscopic ultrasound, six were leiomyomas (SMA-positive), one was a schwannoglioma (S-100 positive), and the remaining 55 were stromal tumors.CONCLUSION: Some gastric stromal tumors arising from the muscularis propria can be completely removed by EFR. EFR could likely replace surgical or laparoscopic procedures for the removal of gastric stromal tumors.     

Cooperative laparoscopic endoscopic and hybrid laparoscopic surgery for upper gastrointestinal tumors: Current status

AIM: To investigate the cooperative laparoscopic and endoscopic techniques used for the resection of upper gastrointestinal tumors.METHODS: A systematic research of the literature was performed in PubMed for English and French language articles about laparoscopic and endoscopic cooperative, combined, hybrid and rendezvous techniques. Only original studies using these techniques for the resection of early gastric cancer, benign tumors and gastrointestinal stromal tumors of the stomach and the duodenum were included. By excluding case series of less than 10 patients, 25 studies were identified. The study design, number of cases, tumor pathology size and location, the operative technique name, the endoscopy team and surgical team role, operative time, type of closure of visceral wall defect, blood loss, complications and length of hospital stay of these studies were evaluated. Additionally all cooperative techniques found were classified and are presented in a systematic approach.RESULTS: The studies identified were case series and retrospective cohort studies. A total of 706 patients were operated on with a cooperative technique. The tumors resected were only gastrointestinal stromal tumors (GIST) in 4 studies, GIST and various benign submucosal tumors in 22 studies, early gastric cancer (pT1a and pT1b) in 6 studies and early duodenal cancer in 1 study. There was important heterogeneity between the studies. The operative techniques identified were: laparoscopic assisted endoscopic resection, endoscopic assisted wedge resection, endoscopic assisted transgastric and intragastric surgery, laparoscopic endoscopic cooperative surgery (LECS), laparoscopic assisted endoscopic full thickness resection (LAEFR), clean non exposure technique and non-exposed endoscopic wall-inversion surgery (NEWS). Each technique is illustrated with the roles of the endoscopic and laparoscopic teams; the indications, characteristics and short term results are described.CONCLUSION: Along with the traditional cooperative techniques, new procedures like LECS, LAEFR and NEWS hold great promise for the future of minimally invasive oncologic procedures.     

Laparoscopic-endoscopic cooperative surgery for gastric submucosal tumors

AIM:To assess the feasibility,safety,and advantages of minimally invasive laparoscopic-endoscopic cooperative surgery(LECS)for gastric submucosal tumors(SMT).METHODS:We retrospectively analyzed 101 consecutive patients,who had undergone partial,proximal,or distal gastrectomy using LECS for gastric SMT at Peking Union Medical College Hospital from June 2006to April 2013.All patients were followed up by visit or telephone.Clinical data,surgical approach,pathological features such as the size,location,and pathological type of each tumor;and follow-up results were analyzed.The feasibility,safety and effectiveness of LECS for gastric SMT were evaluated,especially for patients with tumors located near the cardia or pylorus.RESULTS:The 101 patients included 43(42.6%)menand 58(57.4%)women,with mean age of 51.2±13.1 years(range,14-76 years).The most common symptom was belching.Almost all(n=97)patients underwent surgery with preservation of the cardia and pylorus,with the other four patients undergoing proximal or distal gastrectomy.The mean distance from the lesion to the cardia or pylorus was 3.4±1.3 cm,and the minimum distance from the tumor edge to the cardia was 1.5 cm.Tumor pathology included gastrointestinal stromal tumor in 78 patients,leiomyoma in 13,carcinoid tumors in three,ectopic pancreas in three,lipoma in two,glomus tumor in one,and inflammatory pseudotumor in one.Tumor size ranged from 1 to8.2 cm,with 65(64.4%)lesions<2 cm,32(31.7%)>2 cm,and four>5 cm.Sixty-six lesions(65.3%)were located in the fundus,21(20.8%)in the body,10(9.9%)in the antrum,three(3.0%)in the cardia,and one(1.0%)in the pylorus.During a median follow-up of 28 mo(range,1-69 mo),none of these patients experienced recurrence or metastasis.The three patients who underwent proximal gastrectomy experienced symptoms of regurgitation and belching.CONCLUSION:Laparoscopic-endoscopic cooperative surgery is feasible and safe for patients with gastric submucosal tumor.Endoscopic intraoperative localization and support can help preserve the

Minimally invasive surgery for gastric cancer: A comparison between robotic,laparoscopic and open surgery

AIM To investigate the role of minimally invasive surgery for gastric cancer and determine surgical, clinical, and oncological outcomes.METHODS This is a propensity score-matched case-control study, comparing three treatment arms: robotic gastrectomy(RG), laparoscopic gastrectomy(LG), open gastrectomy(OG). Data collection started after sharing a specific study protocol. Data were recorded through a tailored and protected web-based system. Primary outcomes: harvested lymph nodes, estimated blood loss, hospital stay, complications rate. Among the secondary outcomes, there are: operative time, R0 resections, POD of mobilization, POD of starting liquid diet and soft solid diet. The analysis includes the evaluation of type and grade of postoperative complications. Detailed information of anastomotic leakages is also provided.RESULTS The present analysis was carried out of 1026 gastrectomies. To guarantee homogenous distribution of cases, patients in the RG, LG and OG groups were 1:1:2 matched using a propensity score analysis with a caliper = 0.2. The successful matching resulted in a total sample of 604 patients(RG = 151; LG = 151; OG = 302). The three groups showed no differences in all baseline patients characteristics, type of surgery(P = 0.42) and stage of the disease(P = 0.16). Intraoperative blood loss was significantly lower in the LG(95.93 ± 119.22) and RG(117.91 ± 68.11) groups compared to the OG(127.26 ± 79.50, P = 0.002). The mean number of retrieved lymph nodes was similar between the RG(27.78 ± 11.45), LG(24.58 ± 13.56) and OG(25.82 ± 12.07) approach. A benefit in favor of the minimally invasive approaches was found in the length of hospital stay(P 0.0001). A similar complications rate was found(P = 0.13). The leakage rate was not different(P = 0.78) between groups.CONCLUSION Laparoscopic and robotic surgery can be safely performed and proposed as possible alternative to open surgery. The main highlighted benefit is a faster postoperative functional recovery.

Effectiveness and safety of reduced-port laparoscopic surgery vs conventional multi-port laparoscopic surgery in the treatment of gastric diseases: A meta-analysis

This study aimed to compare the effectiveness and safety of reduced-port laparoscopic surgery (RPLS) and conventional multi-port laparoscopic (CMPLS) surgery in the treatment of gastric diseases.The PubMed, Embase, Cochrane Library, Web of Science, and Chinese Biomedical Literature databases were systematically searched for randomized controlled trials, cohort studies, and case control studies on the use of RPLS vs conventional multi-port laparoscopic surgery in treating gastric diseases from their inception until March 10, 2019. The evaluated outcomes were the operative time, blood loss, length of hospital stay, number of dissected lymph nodes, postoperative complications, and conversions. All of these were compared using Stata software version 12.0.A total of 18 studies were included, which involved 2938 patients. In studies referring to the comparison between RPLS and CMPLS in treating gastric diseases, the former showed significantly inferior in terms of operative time (P = .011) and number of dissected lymph nodes (P = .031); but superior results in terms of the estimated blood loss (P = .000) and length of hospital stay (P = .001) than the latter did; however, the rates of postoperative complications (P = .830) and conversions (P = .102) were not statistically significant between the 2 groups.RPLS and CMPLS showed comparable effectiveness and safety in the treatment of gastric diseases in our meta-analysis. Based on the current evidence, we believe that RPLS is an efficacious surgical alternative to CMPLS in the management of gastric diseases because of the shorter hospital stay and reduced blood loss. However, large-scale, well-designed, multicenter studies are needed to further confirm the results of this study.     

Enhanced recovery after surgery for laparoscopic gastrectomy in gastric cancer: A prospective study

Background:Laparoscopic distal gastrectomy (LDG) has been highlighted for its safety and better short-term clinical outcomes in treating gastric cancer. However, only a slight reduction of the post-operative hospital stay was observed in gastric cancer patients undergoing LDG with conventional perioperative management, compared to patients undergoing open surgery. Thus, an enhanced recovery after surgery (ERAS) program for LDG is needed to further reduce the post-operative hospital stays. This prospective, open-label, single-arm cohort study aimed to assess the safety and efficacy of the ERAS program for gastric cancer patients undergoing LDG.Material and Methods:All patients with gastric cancer indicated for LDG were consecutively enrolled from December 2016 to January 2018. The ERAS program included short fasting time, effective perioperative pain management, early, goal-oriented ambulation, and oral feeding. The safety assessment was the incidence of post-operative complications, mortality, and readmission in 30 days. The primary efficacy assessment was recovery time defined by post-operative hospital stays and rehabilitative rate on post-operative day 4.Results:Ninety-eight of 114 patients were finally enrolled. The incidence of post-operative complication, mortality, and readmission in 30 days was 20. 4%, 0%, 7.1%, respectively. The Clavien-Dindo grade III complication rate was 6.1%, while the pulmonary complication rate was 1% only. The median post-operative stay was 6 days (5.0-7.0 days), and the rehabilitative rate on post-operative day 4 was 78%.Conclusions:The ERAS program might be optimal perioperative management for gastric cancer patients after LDG without compromising safety.Trial number:{"type":"clinical-trial","attrs":{"text":"NCT03016026","term_id":"NCT03016026"}}NCT03016026     

The current status and future perspectives of laparoscopic surgery for gastric cancer

The incidence of early gastric cancer (EGC) has increased to over 50% in Korea and Japan due to rapid advances in diagnostic instrumentation and increased use of mass screening. Considering the excellent prognosies of EGC patients, the quality of life of these patients after treatment has recently been emphasized. For the better quality of life, laparoscopic surgery has emerged as an alternative therapy for EGC patients. Since Kitano et al. first performed laparoscopy-assisted distal gastrectomy (LADG) for early gastric cancer in 1991, it has been performed worldwide, especially in Japan and Korea. A number of reports have presented the excellent short term outcomes; less pain, better cosmetics, faster recovery, and shorter hospital stay. However, there is little evidence of the oncological outcome of laparoscopic gastrectomy as a treatment modality for gastric cancer. Multi-center randomized controlled trials of laparoscopic versus open gastrectomy are needed to establish the future role of laparoscopic surgery in the treatment of patients with gastric cancer.

Intragastric surgery using laparoscopy and oral endoscopy for gastric submucosal tumors

We review the techniques and outcomes of the intragastric resection for gastric submucosal tumors (GSTs) using laparoscope and oral endoscope. In the literature, the mean operation time, intraoperative blood loss, pathological size of the tumor and postoperative hospital stay were 134 min, minimal, 31 mm and 6.4 d, respectively. There were no particular perioperative complications during the follow-up period (mean: 121.3 mo). Intragastric surgery using laparoscopy and oral endoscopy can be considerably beneficial for patients with GSTs locating in the upper third of the stomach between 2-5 cm in diameter and < 8 cm² in cross-sectional area and located in the upper third of the stomach.     

Bone-marrow-derived cells for enhancing collateral development: mechanisms, animal data, and initial clinical experiences

Initial animal studies of single angiogenic agents, such as vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF), generated enthusiasm for the concept that these agents might enhance collateral development and thereby provide alternative therapies for patients with vascular disease not amenable to traditional revascularization. The enthusiasm, apparently justified by the subsequent results of small nonrandomized phase-I clinical trials, was then tempered by the subsequent disappointing results of randomized clinical trials. In light of these disappointing results, investigators have pursued alternative strategies in an attempt to improve tissue perfusion. One such strategy is the utilization of bone marrow-derived cell therapy. This review discusses mechanistic pathways mediating the effects of such cell therapy, summarizes the animal and early clinical experience, and speculates on the potential of genetic manipulation of bone marrow-derived cells in an attempt to further enhance their potency.
