Abstract
INTRODUCTION AND IMPORTANCE GIST (Gastro Intestinal Stromal Tumor) treatment is surgical however surgical resection, especially for gGIST (gastric GIST), may be challenging due to location of tumor and the possible sequelae post resection. CASE PRESENTATION We present a case of 66-year-old female presented for the management of gGIST. We opted for transgastric resection assisted by robot. The resection was with free surgical margins for a 4 cm GIST tumor low in grade. CLINICAL DISCUSSION Classical wedge resection of gastric tumors poses post-operative complications especially if the tumor is located near the cardia or pylorus. Various minimally invasive techniques were described aiming to avoid post-operative complications as in stenosis and gastric reflux. CONCLUSION Minimally invasive transgastric resection of gGIST tumor seems to be worth of attention for it can prevent stenosis, hemorrhage and can preserve gastric tissue. Further studies need to be involved to endorse this technique.

Abstract
Background and study aims Laparoscopic and endoscopic cooperative surgery (LECS) for gastric submucosal tumor was developed as a type of minimal local resection and is now widely used in Asian countries. However, the oncological safety of LECS for gastric gastrointestinal stromal tumor (GIST) remains unclear. LECS has potential oncology-related problems that may influence survival outcomes. Furthermore, the feasibility and safety of LECS have not yet been fully established. Patients and methods Patients who were intended to undergo LECS for gastric GIST from 2006 to 2020 were retrospectively selected. The indication for LECS was determined according to the guidelines. The completion of LECS, complications, and survival outcomes of the patients were analyzed. Results Two hundred fifty-nine patients were eligible in this study. According to intraoperative findings, 44 patients underwent local resection without luminal endoscopic procedures. Of the remaining 215 patients, 213 completely underwent LECS, which corresponds to a completion rate of 99.1 %. Six patients (2.8 %) had postoperative complications of Clavien-Dindo classification grade II or higher. Delayed gastric emptying was most commonly found in four patients (1.9 %). Old age ( P = 0.0349), female sex ( P = 0.0095), tumor located in the lesser curvature ( P = 0.0015), and large tumor diameter ( P = 0.0232) were significantly more common in patients with complications. The 3-year overall and disease-specific survival rates were 99 % and 100 %, respectively, in 215 patients who were intended to undergo LECS. Conclusions Despite several oncological concerns, LECS for gastric GIST is oncologically safe besides a feasible and safe procedure in the short-term.

A Nomogram for Predicting Laparoscopic and Endoscopic Cooperative Surgery during the Endoscopic Resection of Subepithelial Tumors of the Upper Gastrointestinal Tract. Diagnostics (Basel) 2021; 11:diagnostics11112160. [PMID: 34829507 PMCID: PMC8624280 DOI: 10.3390/diagnostics11112160] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Revised: 11/15/2021] [Accepted: 11/17/2021] [Indexed: 12/12/2022] Open
Abstract
Background: Considering the widespread use of esophagogastroduodenoscopy, the prevalence of upper gastrointestinal (GI) subepithelial tumors (SET) increases. For relatively safer removal of upper GI SETs, endoscopic submucosal dissection (ESD) has been developed as an alternative to surgery. This study aimed to analyze the outcome of endoscopic resection for SETs and develop a prediction model for the need for laparoscopic and endoscopic cooperative surgery (LECS) during the procedure. Method: We retrospectively analyzed 123 patients who underwent endoscopic resection for upper GI SETs between January 2012 and December 2020 at our institution. Intraoperatively, they underwent ESD or submucosal tunneling endoscopic resection (STER). Results: ESD and STER were performed in 107 and 16 patients, respectively. The median age was 55 years, and the average tumor size was 1.5 cm. En bloc resection was achieved in 114 patients (92.7%). The median follow-up duration was 242 days without recurrence. Perforation occurred in 47 patients (38.2%), and 30 patients (24.4%) underwent LECS. Most perforations occurred in the fundus. Through multivariable analysis, we built a nomogram that can predict LECS requirement according to tumor location, size, patient age, and sex. The prediction model exhibited good discrimination ability, with an area under the curve (AUC) of 0.893. Conclusions: Endoscopic resection is a noninvasive procedure for small upper-GI SETs. Most perforations can be successfully managed endoscopically. The prediction model for LECS requirement is useful in treatment planning.

Feasibility of Non-Exposure Simple Suturing Endoscopic Full-Thickness Resection in Comparison with Laparoscopic Endoscopic Cooperative Surgery for Gastric Subepithelial Tumors: Results of Two Independent Prospective Trials. Cancers (Basel) 2021; 13:cancers13081858. [PMID: 33924610 PMCID: PMC8069039 DOI: 10.3390/cancers13081858] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2021] [Revised: 03/30/2021] [Accepted: 04/07/2021] [Indexed: 12/14/2022] Open
Abstract
Simple Summary Nonexposure simple suturing endoscopic full-thickness resection (NESS-EFTR) is a recently developed method to prevent the exposure of tumor cells, and we performed a small prospective trial of NESS-EFTR for gastric subepithelial tumors (SETs). In this study, we compared the results of NESS-EFTR trial with those of another small prospective trial of laparoscopic and endoscopic cooperative surgery which was performed in different time period. The results of this study show the feasibility of NESS-EFTR for gastric SETs and provide evidence for the clinical application of the NESS-EFTR procedure. Abstract Recently, nonexposure simple suturing endoscopic full-thickness resection (NESS-EFTR) method was developed to avoid tumor exposure to the peritoneal cavity. The aim of this study is to compare the short-term outcomes of the NESS-EFTR method with those of laparoscopic and endoscopic cooperative surgery (LECS) for gastric subepithelial tumors (SETs). A prospective single-center trial of LECS for gastric SETs was performed from March 2012 to October 2013 with a separate prospective trial of NESS-EFTR performed from August 2015 to June 2017, enrolling 15 patients each. Among the 30 enrolled patients, 14 who underwent LECS and 11 who underwent NESS-EFTR were finally included in the analysis. The rate of complete resection and successful closure was 100% in both groups. The operating time was longer for NESS-EFTR group than for LECS (110 vs. 189 min; p < 0.0001). There were no postoperative complications except one case of transient fever in the NESS-EFTR group. One patient in the LECS group had peritoneal seeding of gastrointestinal stromal tumor at 17 months postoperatively, and there was no other recurrence. Although NESS-EFTR had long operating and procedure times, it was feasible for patients with gastric SETs requiring a nonexposure technique.

Abstract
Background and Objectives The objective was to assess the efficacy and safety in treating gastric stromal tumours by laparoscopy combined with gastroscopy positioning surgery. Methods The randomised controlled trials (RCTs), which are about the efficacy and safety of laparoscopy combined with gastroscopy positioning surgery in treating gastric stromal tumours were searched from the PubMed (1998-1990-2018.6), Wanfang Data (1990-2018.6), China National Knowledge Infrastructure (1979-2018.6) and International Statistical Institute (1998-2018.6). The data were extracted from these trials, and the meta-analysis was made through from RevMan 5.3 software. Results Six RCTs involving 451 patients were included in the study (227 patients in the laparoscopy combined with gastroscopy positioning group and 224 patients in laparoscopic surgery group). Compared with laparoscopic surgery group, this meta-analysis showed that laparoscopy combined with gastroscopy positioning group could shorten the post-operation hospital stay (P < 0.05) and reduce the intraoperative blood loss (P < 0.05). However, there was no significant difference in others between the two groups, such as operation time (P > 0.05), post-operative time of recovery of intestinal peristalsis (P > 0.05) and the total hospital stay (P > 0.05). Conclusion Compared with laparoscopic surgery group, the better total effect occurs in laparoscopy combined with gastroscopy positioning group for the treatment of gastric stromal tumours is better. Laparoscopy combined with gastroscopy positioning group for the gastric stromal tumours is acceptable.

Abstract
BACKGROUND Endoscopic submucosal tunneling has evolved to allow endoscopic resection of subepithelial tumors of gastrointestinal tract without full-thickness perforation. This study aimed to investigate safety and efficacy of submucosal tunnel resection for these tumors. METHOD Patients with subepithelial tumors (SET) located in esophagus, gastric cardia, lesser curvature, and antrum were recruited. The size of tumor was limited to < 40 mm. The procedures were performed under general anesthesia. A mucosal entrance was created 2 cm proximal to the SET after submucosal injection. Submucosal tunnel was then extended and the tumor was dissected and mobilized with intact overlying mucosa. After complete dissection, the tumors would be retrieved per orally and mucosal entrance closed by endoclips. RESULTS From June 2012 to December 2016, 51 patients with subepithelial tumors received POET. 39 patients had SET in stomach, 11 located in esophagus, and 1 in duodenum. The mean operative time was 90.46 ± 46.49 min, while the mean size of the tumors was 20.71 ± 14.05 mm. The POET was converted to endoscopic full-thickness resection (EFTR) in three patients with gastric subepithelial tumors located at greater curvature. The overall complication rate was 4.0%, and there was no bleeding, mucosal dehiscence, or leakage. The time to resume diet was 1.7 days, while the average hospital stay was 3.2 ± 1.0 days. The mean follow-up period was 19 ± 16 months, and only 1 patient developed recurrence of leiomyoma. CONCLUSION Per oral endoscopic tumor resection is safe and effective treatment for esophageal and gastric SET located at cardia, lesser curvature, and antrum. Currently, POET for treatment of upper GI SET is limited by the size and location of the tumor.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is currently the most frequently performed bariatric procedure in Turkey. The goal of weight reduction surgery is not only to decrease excess weight, but also to improve obesity related comorbidities and quality of life (QoL). AIM To evaluate the impact of LSG on patient quality of life, weight loss, and comorbidities associated with morbid obesity according to the updated BAROS criteria. METHODS Eleven hundred thirty-eight adult patients were undergone to LSG by our bariatric surgery team between January 2013 and January 2016. A questionnaire (The Bariatric Analysis and Reporting Outcome System - BAROS) was published on social media. The data on postoperative complications were collected from hospital database. RESULTS Number of respondants was 562 (49.4%). Six of 1138 patients(0.5%) had leakage. All patients who had leakage were respondants. The overall complication rate was 7.7%. After a mean period of 7.4±5.3 months(1-30), mean excess weight loss was 71.3±27.1% (10.2-155.4). The respondants reported 772 comorbidities. Of these, 162 (30%) were improved, and 420 (54.4%) were resolved. The mean scores for QoL were significantly increased after LSG (range, p<0.05 to <0.001). Of the 562 patients, 26 (4.6%) were classified as failures; 86 (15.3%) fair; 196 (34.9%) good; 144 (25.6%) very good, and 110 (19.6%) excellent results according to the updated BAROS scoring system. CONCLUSION LSG is a highly effective bariatric procedure in the manner of weight control, improvement in comorbidities and increasing of QoL in short- and mid-term.

Abstract
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors located in the alimentary tract. Its usual manifestation is gastrointestinal bleeding. However, small asymptomatic lesions are frequently detected as incidental finding. Characteristically, most GISTs (> 95%) are positive for the KIT protein (CD117) by IHC staining and approximately 80%-90% of GISTs carry a mutation in the c-KIT or PDGFRA genes. Mutational analysis should be performed when planning adjuvant and neoadjuvant therapy, due to its possible resistance to conventional treatment. The arise of tyrosine kinase inhibitor has supposed a revolution in GISTs treatment being useful as adjuvant, neoadjuvant or recurrence disease treatment. That is why a multidisciplinary approach to this disease is required. The correct characterization of the tumor at diagnosis (the diagnosis of recurrences and the evaluation of the response to treatment with tyrosine kinase inhibitors) is fundamental for facing these tumors and requires specialized Endoscopist, Radiologists and Nuclear Medicine Physician. Surgery is the only potentially curative treatment for suspected resectable GIST. In the case of high risk GISTs, surgery plus adjuvant Imatinib-Mesylate for 3 years is the standard treatment. Neoadjuvant imatinib-mesylate should be considered to shrink the tumor in case of locally advanced primary or recurrence disease, unresectable or potentially resectable metastasic tumors, and potentially resectable disease in complex anatomic locations to decrease the related morbidity. In the case of Metastatic GIST under Neoadjuvant treatment, when there are complete response, stable disease or limited disease progression, complete cytoreductive surgery could be a therapeutic option if feasible.

Abstract
BACKGROUND Laparoscopic resection for gastric gastrointestinal stromal tumors (GISTs) is technically feasible, but the long-term effect remains uncertain. This study aims to compare the long-term oncologic outcomes of laparoscopic versus open resection of GISTs by larger cases based on tumor size-location-matched study. METHODS Between 2006 and 2015, 63 consecutive patients with a primary gastric GIST undergoing laparoscopic resection were enrolled in and matched (1:1) to patients undergoing open resection by tumor size and location. Clinical and pathologic parameters and surgical outcomes associated with each surgical type were collected and compared. RESULTS The operation time, intraoperative blood loss, return of bowel function and oral intake, nasogastric tube retention time and postoperative stay were all shorter/faster in laparoscopic group than those in open group (P < 0.001). Postoperative complications were comparable except for the higher incidence of abdominal/incision pain in open group (9.52 vs 27%, P = 0.01). There was no statistical difference in recurrence rate (9.52 vs 15.87%, P = 0.29) and long-term recurrence-free survival between the two groups (P = 0.39). CONCLUSIONS The long-term oncologic outcome of laparoscopic resection of primary gastric GISTs is comparable to that of open procedure, but laparoscopic procedure has the advantage of minimal invasion and is superior in postoperative recovery.

Abstract
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors in the gastrointestinal tract, and about 60% of them are found in the stomach. With the widespread application of endoscopy and endoscopic ultrasonography (EUS), more and more gastric GISTs are being found in an early stage (with a relative small diameter and no metastasis), giving the chance of complete resection. Endoscopic resection such as endoscopic band ligation (EBL), endoscopic submucosal dissection (ESD), endoscopic submucosal excavation (ESE), endoscopic full-thickness resection (EFTR) and submucosal tunneling endoscopic resection (STER), is a minimally invasive method compared with the conventional surgical approaches (open or laparoscopic), and has been demonstrated to be safe and effective for treating gastric GISTs. This review summarizes the recent advances on endoscopic resection of gastric GISTs, aiming to provide a rational management strategy for gastric GISTs.

Abstract
BACKGROUND The technical feasibility and oncological safety of laparoscopic surgery for gastric gastrointestinal stromal tumors (GISTs) larger than 5 cm has not been adequately studied. Therefore, we performed this retrospective study to investigate the clinical outcomes of gastric GIST patients treated with laparoscopic surgery compared with those who underwent open surgery. METHODS We retrospectively evaluated the outcomes of 48 consecutive patients who underwent gastric resection for gastric GISTs larger than 5 cm. The patients were divided into 2 groups based on the surgery performed: the laparoscopic resection group (LAPG) and the open resection group (OG). We assessed all available patient data, including baseline information, tumor characteristics, surgical outcomes, pathological results, postoperative complications, and long-term patient survival. RESULTS The 2 groups had similar baseline data. No differences were found in tumor size, location, mitotic count, and risk grade according to Fletcher's risk classification. The LAPG was superior to the OG in blood loss, time to first flatus, time to oral intake, and length of postoperative hospital stay. Perioperative complications, recurrence rate, and long-term survival, however, did not differ significantly between the groups. The mean operation time in the LAPG was 28 minutes longer than that in the OG. CONCLUSIONS In patients with primary gastric GISTs larger than 5 cm, laparoscopic resection is a technically feasible and oncologically safe surgery when performed by experienced surgeons.

Abstract
This article investigated the feasibility of laparoscopic surgery in unfavorable site gastric gastrointestinal stromal tumors (GISTs).We identified 214 patients who underwent primary gastric GIST resection at our institution (January 2006-December 2014) from a prospectively collected database. These patients were divided into a Favorable group (140 cases) and an Unfavorable group (74 cases) according to the 2014 version of the National Comprehensive Cancer Network Clinical Guidelines (NCCN guidelines).The wedge resection rate of the Favorable group was higher than that of the Unfavorable group, and most procedures were performed laparoscopically (P < 0.05). In addition, there were no differences in the other clinicopathological features between these groups (P > 0.05). The postoperative stay of the Unfavorable group was longer than that of the Favorable group (P = 0.02). Laparoscopic surgery in both groups resulted in a shorter operative time, lower blood loss, faster time to first flatus, faster time to first fluid diet, and shorter postoperative stay than open surgery (P < 0.05). Although the difference was not significant (P = 0.09), the postoperative complication incidence of the Favorable group was less than that of the Unfavorable group (10% vs 17.6%). Furthermore, in the Unfavorable group, the incidence of postoperative complications from laparoscopic surgery was significantly lower than that of open surgery (P = 0.001). There were no differences in the 5-year overall survival (OS) and recurrence-free survival (RFS) of these groups (P > 0.05). Furthermore, in the Unfavorable group, the 5-year OS and RFS were similar for both laparoscopic and open procedures. Multivariate Cox regression analysis showed that imatinib (IM) treatment was an independent risk factor for poor prognosis.Laparoscopic operation for gastric GISTs located in unfavorable sites can yield similar long-term outcomes compared with an open operation. However, laparoscopic surgery has the obvious advantage of being minimally invasive, and the incidence of postoperative complications was low. Laparoscopic surgery is thus an option for the treatment of localized gastric GISTs.

Abstract
OBJECTIVE Laparoscopy-assisted endoscopic full-thickness resection (LAEFTR) has been suggested as an alternative to laparoscopic wedge resection in the treatment of gastric subepithelial tumors (SETs). It is expected to minimize the resection of the tissue surrounding the tumors and maintain the function of the remnant stomach. Here, we performed a prospective pilot study to evaluate the efficacy of laparoscopy-assisted endoscopic full-thickness resection (LAEFTR) for patients with gastric SETs. MATERIAL AND METHODS We enrolled twelve patients who were diagnosed with gastric SETs with an intraluminal growth pattern or which is located in the gastric antrum between October 2011 and September 2013. LAEFTR was performed endoscopically using an endoscopic knife to make an incision half way around the tumor circumference and a laparoscopic resection around the remaining tumor circumference, followed by its laparoscopic removal. The feasibility, safety, and effectiveness of LAEFTR for gastric SETs were evaluated. RESULTS The median size of the tumors in twelve patients was 22 mm (21-33). Of the 12 patients, 8 received LAEFTR, while the others underwent conventional laparoscopic wedge resection, since their tumor outlines were clearly visible in laparoscopic view. In 8 patients who underwent LAEFTR, the mean total operation time (endoscopic procedure time/laparoscopic procedure time) were 117 (37/41) min. The tumors were completely resected with clear margin, and there was no perioperative and postoperative complications. CONCLUSIONS LAEFTR currently seems to be the ideal treatment modality of intraluminal gastric SETs where their resection margins are difficult to define under laparoscopic guidance alone.

Abstract
INTRODUCTION To minimize the resection of stomach tissue, especially for lesions close to the esophagogastric junction or pyloric ring, we developed laparoscopic wedge resection with the serosal and muscular layers incision technique (SAMIT) for gastric gastrointestinal stromal tumors. MATERIALS AND SURGICAL TECHNIQUE SAMIT involves resection of the mucosal and submucosal layers and then an incision in serosal and muscular layers around the tumor. SAMIT is simple and does not require special devices. The data of 13 patients who underwent laparoscopic wedge resection with SAMIT for primary gastric gastrointestinal stromal tumors were reviewed. No intraoperative complications were observed, and postoperative stenosis occurred in only one case of a middle stomach lesion. Adequate oncological resection was performed in all cases. DISCUSSION Laparoscopic wedge resection with SAMIT is technically and oncologically safe. It is useful for treating gastric gastrointestinal stromal tumors, including those close to the esophagogastric junction or pyloric ring.

Abstract
BACKGROUND Although the feasibility of minimally invasive resection of small gastric GISTs is well established, less is known about safety and efficacy of laparoscopic surgery for large tumors. METHODS A retrospective analysis was performed, using a prospectively maintained comprehensive database. Patients were divided into two groups according to tumor size: Case group with tumors > 5 cm and control group with tumors <5 cm. Hospital charts were reviewed, and various outcome measures recorded, including operative time, estimated operative blood loss, post-operative leak, stasis, infection and recurrence. RESULTS No tumors were ruptured during surgical manipulation and no major morbidity or mortality occurred in either group. Operative time (75,8 ± 33,1 min in large cases vs 75,8 ± 33,1 min in small cases) was similar in both groups (p = 0,61). The incidence of post-operative complications did not differ between the two groups. In details there were 21 out of 25 (84%) uncomplicated cases among small GISTs versus 17 out of 24 (70,8%) uncomplicated cases among large GISTs (p = 0,32). CONCLUSION This matched-pair case control study demonstrates that laparoscopic wedge resection for large gastric GISTs is safe and effective, as demonstrated for small tumors.

Comparison between submucosal tunneling endoscopic resection and endoscopic full-thickness resection for gastric stromal tumors originating from the muscularis propria layer. Surg Endosc 2016; 31:3376-3382.

Abstract
BACKGROUND Both submucosal tunneling endoscopic resection (STER) and endoscopic full-thickness resection (EFTR) are effective method for treating gastric gastrointestinal stromal tumors (GISTs); however, little is known about the comparison between STER and EFTR. The aim of the study was to compare the safety and efficacy of STER and EFTR for treating gastric GIST. METHODS We retrospectively collected the clinical data about patients with gastric GISTs who received STER or EFTR at our hospital from April 2011 to June 2016. Epidemiological data (gender, age), tumor size, procedure-related parameters, complications, length of stay, cost and follow-up data were compared between STER and EFTR. RESULTS A total of 52 patients were enrolled, and 20 of them received STER, while the other 32 cases received EFTR. There was no significant difference between the two groups in terms of gender, age, concomitant diseases, tumor size, en bloc resection rate, operation time, complications, pathohistological grade of GIST, hospital stay and cost (P > 0.05). However, patients who received EFTR had a longer suture time and needed more clips to close the gastric-wall defect (STER vs EFTR, 291.5 ± 68.7 vs 380.6 ± 96.9s and 6.0 ± 1.2 vs 7.6 ± 1.6, P < 0.05). No recurrence was noted in the STER and EFTR groups during a mean follow-up of 10.9 and 23.8 months, respectively. CONCLUSIONS The treatment efficacy between STER and EFTR for treating gastric GISTs was comparable, and a large-scale, randomized study is necessary for a more confirmed conclusion.

Abstract
BACKGROUND Laparoscopic endoscopic cooperative surgery (LECS) is a safe alternative to endoscopic submucosal dissection (ESD) for select gastric gastrointestinal stromal tumors (GISTs) that are <2 cm in size. To date, there have been no randomized studies comparing the feasibility of these two techniques. Therefore, we compared their feasibility and safety using the propensity score matching method in this study. METHODS This was a single-center, retrospective, propensity score-matched study of patients who underwent resection of selected gastric GISTs between 2004 and 2014. All patients underwent curative resection for pathologically diagnosed small gastric GISTs. The primary aim was to determine intraoperative complications and postoperative courses. To overcome selection biases, we performed a 1:1 match using five covariates, including age, gender, body mass index, Charlson comorbidity index, and tumor location, to generate propensity scores. RESULTS In total, 32 patients treated with LECS and 102 patients treated with ESD were balanced into 30 pairs. The rate of intraoperative complications was significantly lower in the LECS group than in the ESD group (P = 0.029). LECS patients had less intraoperative bleeding than did ESD patients (15.0 ml [range 9.5-50.0 ml] vs. 43.5 ml [range 22.3-56.0 ml], P = 0.004). The two groups had similar postoperative courses. There was no difference in the reoperation rate between the two groups (P = 0.112). The ESD group had a shorter operating time than did the LECS group (41.5 min vs. 96.5 min, P < 0.001). However, during a follow-up of 57.9 (±28.9) months, the recurrence rate did not differ significantly between the two groups (0.0 vs. 6.7 %, respectively; P = 0.256). CONCLUSIONS LECS for selected gastric GIST patients is feasible and is associated with a better intraoperative outcome and an equal postoperative course compared with the results of ESD.

Abstract
BACKGROUND There is some concern that wedge resection of gastric gastrointestinal stromal tumors is not feasible in certain anatomic locations, such as the cardia or antrum. We sought to review our experience with treatment of gastric gastrointestinal stromal tumors with a particular focus on nonanatomic wedge resections in these challenging locations. METHODS Patients undergoing resection of gastrointestinal stromal tumors from 2000-2014 at the Montreal General Hospital were identified from a prospectively collected database, and outcomes were tabulated. An individualized operative strategy was used to guide resection based on tumor location, size, and characteristics. Disease-free survival and overall survival analyzed using the Kaplan-Meier method. Data are presented as median (range). RESULTS We identified 59 patients who underwent operative resection for gastric gastrointestinal stromal tumors. Tumor location was fundus/body/greater curvature in 35 (59%) patients, lesser curvature in 8 (14%) patients, antrum in 8 (14%) patients, and cardia in 8 (14%) patients. Median tumor size was 4.5 cm (1.4-25 cm). The majority of cardia and antral lesions were removed with wedge resections (14/16, 87%). For cardial and antral tumors, on-table gastroscopy was used to guide the operative approach and prevent narrowing of the Gastroesophageal junction or pylorus in all patients undergoing wedge resection. Negative pathologic margins were achieved in all patients. The 5-year disease-free survival was 91% and 5-year overall survival was 95%. CONCLUSION When selected appropriately, and under the guidance of on-table gastroscopy, laparoscopic nonanatomic wedge resection can be performed successfully in the majority of cases, even for gastrointestinal stromal tumors near the GEJ or pylorus, with excellent oncologic outcomes.

Feasibility of laparoscopic and endoscopic cooperative surgery for gastric submucosal tumors (with video). Gastrointest Endosc 2016; 84:47-52. [PMID: 26684599 DOI: 10.1016/j.gie.2015.11.040] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2015] [Accepted: 11/25/2015] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND AIMS Laparoscopic gastric resection is widely used for gastric submucosal tumors (SMTs). However, determining an appropriate resection line using only the laparoscopic approach is difficult. We developed a laparoscopic and endoscopic cooperative surgery (LECS) technique by combining laparoscopic gastric resection with endoscopic submucosal dissection, and we have used this procedure to resect gastric SMTs. In this study, the procedure is presented and its safety and feasibility for resecting gastric SMTs are evaluated. METHODS This retrospective study included 100 patients who underwent LECS for SMTs at the Department of Gastroenterological Surgery, Cancer Institute, between June 2006 and November 2014. The demographics, tumor histopathologic characteristics, and operative and follow-up data were reviewed. RESULTS Complete resection with negative surgical margins was achieved in all patients, and LECS was performed regardless of tumor location. The mean operation time was 174.3 minutes, with an estimated blood loss of 16.3 mL. In addition, the mean time until the initiation of oral intake was 1.4 days, and the mean postoperative hospital stay was 8.4 days. Moreover, no local or distant tumor recurrence was observed. The only severe adverse event was leakage, which was observed in 1 patient. CONCLUSIONS LECS was performed with a reasonable operation time, low blood loss, and minimal adverse events. Therefore LECS is safe and feasible for resecting gastric SMTs.

Abstract
The present study reports a novel approach to laparoscopic and endoscopic cooperative surgery for gastric gastrointestinal stromal tumor (GIST) resection and cholecystectomy, and conducts a review of the associated literature. The novel surgical procedure was performed on one patient who was diagnosed with a GIST and cholecystic polypus. The GIST was resected using an insulation-tipped diathermic electrosurgical knife under the guide of an endoscope. Subsequently, a cholecystectomy was performed by inserting two more 5-mm trocars and instruments transumbilically, guided using an endoscope. The tumor and the gallbladder were exteriorized using a peroral approach and the incision lining of the stomach was sutured laparoscopically. The procedure was successfully performed and the patient experienced no discomfort during the 5-year follow-up. In conclusion, the present study demonstrates that laparoscopic and endoscopic cooperative surgery is feasible and would be an ideal choice for invisible abdominal scar surgery, in particular for multi-visceral resection.

Abstract
BACKGROUND Gastric stromal tumors arising from the muscularis propria are located in deeper layers. Endoscopic resection may be contraindicated due to the possibility of perforation. These tumors are therefore usually removed by surgical or laparoscopic procedures. This study evaluated the curative effects, safety and feasibility of endoscopic full-thickness resection (EFR) of gastric stromal tumors originating from the muscularis propria. METHODS This study enrolled 92 patients with gastric stromal tumors >2.5 cm originating from the muscularis propria. Fifty patients underwent EFR, and 42 underwent laparoscopic intragastric surgery. Operation time, complete resection rate, length of hospital stay, incidence of complications, and recurrence rates were compared in these two groups. RESULTS EFR resulted in complete resection of all 50 gastric stromal tumors, with a mean procedure time of 85 ± 20 min, a mean hospitalization time of 7.0 ± 1.5 days and no complications. Laparoscopic intragastric surgery also resulted in a 100% complete resection rate, with a mean operation time of 88 ± 12 min and a mean hospitalization period of 7.5 ± 1.6 days. The two groups did not differ significantly in operation time, complete resection rates, hospital stay or incidence of complications (P > 0.05). No patient in either group experienced tumor recurrence. CONCLUSIONS EFR technique is effective and safe for the resection of gastric stromal tumors arising from the muscularis propria.

Abstract
Sarcomas are a heterogeneous group of rare tumors that originate from mesenchymal tissue. Radical R0 resection is the only curative option, which is especially challenging in retroperitoneal or intra-abdominal sarcomas. This article describes the current data on optimal interdisciplinary and primarily surgical therapy of visceral sarcomas. Surgical resection of retroperitoneal sarcomas must be performed according to the principle of radical compartmental resection, i.e. with complete excision of the mass along with en bloc visceral resection of adjacent organs and tissues covering the tumor, which also contains any not obviously infiltrated neighboring organs. The main objective is R0 resection without opening the tumor capsule in the primary operation because the best long-term results can be achieved with this approach.

Abstract
BACKGROUND AND AIMS Endoscopic resection has been performed for treatment of GI stromal tumors (GISTs) in the upper GI tract. However, the therapeutic roles of the endoscopic procedure remain debatable. We aimed in this retrospective study to evaluate the feasibility and long-term follow-up results of endoscopic resection of GISTs in the upper GI tract, compared with surgery. METHODS Between March 2005 and August 2014, 130 cases of GIST in the upper GI tract were resected. We compared baseline characteristics and clinical outcomes including R0 resection rate and recurrence rate between the endoscopy group (n = 90) and surgery group (n = 40). RESULTS The most common location of GIST was the stomach body in the endoscopy group, whereas it was the duodenum in the surgery group (P = .001). Tumor size was significantly smaller (2.3 vs 5.1 cm; P < .001), and procedure time (51.8 ± 36.2 vs 124.6 ± 74.7 minutes; P < .001) and hospital stay (3.3 ± 2.4 vs 8.3 ± 5.4 days; P < .001) were significantly shorter in the endoscopy group than in the surgery group. The R0 resection rate was 25.6% in the endoscopy group, whereas it was 85.0% in the surgery group (P = .001), and 50.0% of resected tumors belonged to a very low-risk group in the endoscopy group, whereas 35.0% and 30.0% belonged to low-risk and high-risk in the surgery group (P = .001). However, during 45.5 months of follow-up, the recurrence rate was not significantly different between the 2 groups (2.2% vs 5.0%; P = .586). CONCLUSIONS Endoscopic resection might be an alternative therapeutic modality for GISTs in the upper GI tract in selective cases.

Abstract
Purpose Various laparoscopic wedge resection (LWR) techniques requiring gastrotomy for gastrointestinal stromal tumors (GISTs) of the stomach have been applied to facilitate tumor resection and preserve the remnant gastric volume. However, there is the possibility of cancer cell dissemination during these procedures. The aim of this study was to assess the oncologic safety of LWR with gastrotomy (LWR-G) compared to LWR without luminal exposure. Materials and Methods Clinicopathologic and operative results of 193 patients who underwent LWR for gastric GIST were retrospectively analyzed from 2003 to 2013. We stratified the patients into two groups: LWR-G and LWR without gastrotomy (LWR-C). Clinicopathologic features, short-term outcomes, and long-term outcomes were compared. Results A total of 26 patients underwent LWR-G, and 167 patients underwent LWR-C. The LWR-G group showed significantly more anterior wall-located (n=10, 38.5%), intraluminal (n=20, 76.9%), and ulcerative (n=13, 50.0%) tumors than the LWR-C group (n=33, 19.8%; n=96, 57.5%; n=46, 27.5%, respectively). Postoperative short-term outcomes did not differ between the two groups. When tumor staging was compared, no statistical difference was noted. There was no recurrence in the LWR-G group, while 2 patients in the LWR-C group experienced recurrence. The two recurrences in the LWR-C group were found in the liver and in the remnant stomach at 63 and 12 months after the operation, respectively. No gastric GIST-related death was recorded in any group during the study period. Conclusions LWR-G for gastric GIST is an oncologically safe procedure even for masses with ulcerations.

Abstract
To explore the clinicopathologic characteristics, diagnosis, treatment, and prognosis of gastric schwannoma in the imatinib era.The clinicopathologic characteristics and postoperative outcomes of patients diagnosed with gastric schwannoma at our institution between January 2007 and February 2015 were retrospectively collected and analyzed.The main patient complaint was epigastric pain or discomfort. Tumor sizes ranged from 15 to 80 mm (mean, 57.1 mm). In 17 patients, the tumors were located in the body of the stomach. A total of 20 patients were preoperatively misdiagnosed with a gastrointestinal stromal tumor. The rate of correct preoperative diagnosis was only 3.3%. All patients underwent surgical resection and showed strong S-100 protein positivity. Laparoscopic surgery for gastric schwannoma was associated with less blood loss and a shorter postoperative hospital stay than open surgery (P < 0.01). Total 28 patients were disease free without recurrence or metastasis at a median follow-up time of 50 months.Gastric schwannoma is often preoperatively misdiagnosed as gastric gastrointestinal stromal tumor. Laparoscopic resection of gastric schwannoma is considered safe and effective, and it may be the preferred surgery for most small- and moderate-sized tumors. The long-term outcome is excellent, as this type of neoplasm is uniformly benign.

Abstract
Laparoscopic wedge resection is a useful procedure for treating patients with submucosal tumor (SMT) including gastrointestinal stromal tumor (GIST) of the stomach. However, resection of intragastric-type SMTs can be problematic due to the difficulty in accurately judging the location of endoluminal tumor growth, and often excessive amounts of healthy mucosa are removed; thus, full-thickness local excision using laparoscopic and endoscopic cooperative surgery (LECS) is a promising procedure for these cases. Our experience with LECS has confirmed this procedure to be a safe, feasible, and minimally invasive treatment method for gastric GISTs less than 5 cm in diameter, with outcomes similar to conventional laparoscopic wedge resection. The important advantage of LECS is the reduction in the resected area of the gastric wall compared to that in conventional laparoscopic wedge resection using a linear stapler. Early gastric cancer fits the criteria for endoscopic resection; however, if performing endoscopic submucosal dissection is difficult, the LECS procedure might be a good alternative. In the future, LECS is also likely to be indicated for duodenal tumors, as well as gastric tumors. Furthermore, developments in endoscopic and laparoscopic technology have generated various modified LECS techniques, leading to even less invasive surgery.

Abstract
The role of laparoscopic resection for large gastric gastrointestinal stromal tumors (GISTs), particularly those >5 cm, remains under debate due the possibility of intraoperative tumor rupture. To determine the feasibility and safety of the laparoscopic approach in the treatment of large gastric GISTs, a prospective study was performed between March 2011 and March 2014. Intraoperative tumor rupture was studied as the primary outcome. Secondary outcomes were the conversion rate, surgical duration, estimated blood loss, time to tolerate fluid and solid diets, length of post-operative hospital stay and recurrence rate at the end of the follow-up. A total of 16 patients were included in this study, with a tumor size of 7.04±1.53 cm (range, 5.2-10.8 cm). No intraoperative tumor rupture occurred. The median duration of surgery was 88.1±31.9 min, with an estimated blood loss volume of 37.1±18.7 ml. No patient required a blood transfusion. The mean time until the start of oral intake for fluid and solid diets was 1.1±0.6 and 2.5±0.9 days, respectively. The median length of post-operative hospital stay was 5.4±5.8 days. The follow-up period for all patients was 16.9±11.2 months (range, 2-38 months). No local or distant recurrence was observed. The study indicates that laparoscopic resection for large gastric GISTs is feasible and safe. Laparoscopic surgery should be considered as the standard approach in all cases, irrespective of tumor size or location.

Abstract
INTRODUCTION Laparoscopic resection is rapidly becoming the treatment of choice for small- to medium-sized gastric gastrointestinal stromal tumors (GIST). While long-term oncologic data are available, quality of life outcomes are less known. METHODS Our IRB-approved prospectively maintained database was retrospectively queried (2003-2013) for patients who underwent laparoscopic gastric GIST resection. Demographics along with perioperative and oncologic outcomes were collected and analyzed. Patients were contacted and asked to complete a quality of life survey consisting of Likert scales scored from 1 to 5. Patients also completed the Gastrointestinal Quality of Life Index (GIQLI). RESULTS A total of 69 patients were identified and 36 patients (59.0% of eligible patients) responded to the survey. Median follow-up was 39 months. Patients most commonly reported no change in weight, appetite, early satiety, heartburn, persistent cough, dysphagia, and reflux medication dosing postoperatively. The median scores for chest pain and regurgitation were 4, falling in the "worsened" range. 8.33% of patients reported worsened chest pain and 11.11% of patients reported worsened regurgitation postoperatively. The GIQLI scores had a mean of 126.9 (range 77-141). CONCLUSION While some patients reported a worsening in early satiety, most patients reported no change in symptoms postoperatively, and the GIQLI scores remained within the normal range. Laparoscopic resection of gastric GIST provides durable results with minimal effect on longer-term quality of life.

Abstract
BACKGROUND Laparoscopic resection is a standard procedure for gastric submucosal tumors. Herein, we analyzed the features of various laparoscopic approaches. METHODS Between January 2007 and November 2013, 168 consecutive patients who underwent laparoscopic resection for gastric submucosal tumors were enrolled. Patients' demographics and clinicopathologic and perioperative data were reviewed retrospectively. RESULTS Among the 168 patients, exogastric wedge resection was performed in 99 cases (58.9%), single-port intragastric resection was performed in 30 cases (17.9%), eversion technique was used in 17 cases (10.1%), transgastric resection was performed in 8 cases (4.8%), and single-port wedge resection was performed in 6 cases (3.6%). The remaining cases underwent single-port exogastric wedge resection, laparoscopic and endoscopic cooperative surgery, or major resection. Mean age was 56.8 ± 13.3 years, and body mass index was 24.0 ± 3.2 kg/m(2). Mean operation time was 96.1 ± 58.9 min; laparoscopic proximal gastrectomy had the longest operation time (3 cases, 291.7 ± 129.0 min). In contrast, the laparoscopic eversion technique had the shortest operation time (82.6 ± 32.8 min). Pathologic data revealed a mean tumor size of 2.9 ± 1.2 cm (with a range of 0.8-8.0 cm). Tumors were most common on the body (98 cases, 58.3%), followed by the fundus (44 cases, 26.2%). Exophytic growth occurred in 39 cases (23.2%), endophytic growth occurred in 89 cases (53.0%), and dumbbell-type growth occurred in 40 cases (23.8%). Gastrointestinal stromal tumors occurred in 130 cases (77.4%), and schwannomas occurred in 23 (13.7%). Thirteen patients had postoperative complications (delayed gastric emptying in 5, stricture in 3, bleeding in 3, others in 2). The mean follow-up period was 28.8 ± 20.8 months, and there were three recurrences (1.8%) at 6, 19 and 31 months after the initial surgery. CONCLUSIONS For gastric submucosal tumors with appropriate locations and growth types, laparoscopic tailored resection which facilitates safer and more precise resection can be good alternative treatment option.

Abstract
Purpose The standard treatment for primary localized gastric gastrointestinal stromal tumor (GIST) is surgical resection. The clinical behavior of gastric GIST after surgical resection is extremely variable. We conducted a multicenter, retrospective study of gastric GISTs patients who underwent curative surgical resection to evaluate clinical features and the prognosis of surgically treated gastric GISTs. Methods We performed a retrospective study on 406 consecutive patients who underwent curative resections for localized gastric GIST at four university hospitals in Daegu, Korea, between March 1998 and March 2012. The retrospectively collected medical records were reviewed with respect to clinical parameters including age, gender, tumor location, surgical approach, and recurrence. Results There were 406 patients: 157 males (38.7%) and 249 females (61.3%), with a mean age of 60.8 ± 10.8 (standard deviation) years. The mean tumor size was 4.9 cm (range, 0.3-29 cm). Curative surgical resection was performed in all patients without tumor rupture or spillage. Laparoscopic wedge resections were performed in 156 patients (38.4%) and open resections in 250 patients (61.6%). The tumor size of the laparoscopic wedge resection group was smaller than that of open resection group (3.45 cm vs. 5.46 cm; P < 0.001). There were 11 recurrent cases (2.7%). No recurrence was observed in patients who underwent laparoscopic wedge resections. Conclusion Gastric GISTs had a low recurrence rate after curative resection in our series. Laparoscopic gastric wedge resection is feasible for treating gastric GISTs in selected patients.
