Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) techniques, such as generating an artificial space between digestive tract layers for safer dissection, were thought to be safer for the resection of organs in cholecystectomy. We investigated whether combinations of endoscopic techniques and laparoscopic techniques could be performed more safely and rapidly. MATERIAL AND METHODS Laparoscopic and endoscopic cooperative-cholecystectomy (LEC-chole) and conventional laparoscopic cholecystectomy (Lapa-chole) were performed in six dogs. Operation time was defined as the time from the creation of the first port to the retrieval of the resected gallbladder (GB); and GB bed dissection time was the time from local injection of natural saline to the clipping of the cystic duct. The main roles of the endoscope in LEC-chole were to obtain a sufficient cutting space via local injection of natural saline to the GB bed and to monitor the operative view without laparoscopic camera, thus omitting the umbilical port. RESULTS The operation times were 60 ± 18.3 minutes for LEC-chole and 95 ± 7.0 for Lapa-chole (p = .036). The GB bed dissection times were 31 ± 8.54 minutes in LEC-chole and 50.6 ± 7.37 minutes in Lapa-chole (p = 0.048). There were significant differences in liver damage and bleeding (p = 0.116), but there were no significant differences in one-month survival. CONCLUSIONS The application of LEC-chole may be expanded to cholecystectomy.

Abstract
Background and Objectives: Single-port laparoscopic cholecystectomy (SPLC) was introduced to improve patients' postoperative quality of life and cosmesis over the conventional approach (CLC). The purpose of this case–control study was to compare the outcome of SPLC with that of CLC in a specific disease: gall bladder (GB) polyps. Methods: Eligible for the study were all patients with GB polyps who underwent laparoscopic cholecystectomy between June 1, 2009, and June 30, 2011. The 112 patients studied (56 each for SPLC and CLC) were matched by using a propensity score that included gender, age, body mass index (BMI), American Society of Anesthesiologists (ASA) score, history of previous abdominal operation, and pathology outcome. To avoid selection bias caused by the surgeon's choice (often dependent on the degree of inflammation) and to investigate the efficacy of SPLC for a single disease, GB polyps, we excluded patients with acute or chronic cholecystitis. Results: Characteristics of the patients matched by a propensity score between SPLC and CLC showed no significant difference. Incidentally detected malignancy was in postoperative pathology in cases in both groups. Although operative time was shorter for SPLC, there was no significant difference in time between the 2 groups. There were 3 open conversions in the CLC group, and an additional port was used in the SPLC group. There was no difference between the groups in hospital stay and postoperative complications. Conclusion: In the management of GB polyps, the operative results of SPLC are comparable to those of CLC. We conclude that SPLC is as safe as CLC and has the potential for greater cosmetic satisfaction for patients than CLC. Further trials for objective appraisal of cosmetic outcomes are needed.

Abstract
A prospective observational study was conducted to establish the procedure of hybrid endoscopic full-thickness resection (EFTR) using an existing flexible endoscope. The present study included 16 patients who underwent hybrid EFTR between September 2009 and February 2013 for gastric gastrointestinal stromal tumor (GIST). The patients were selected using the following inclusion criteria for histological findings: Mitotic counts <5/high-power field and immunohistochemical stains positive for KIT or cluster of differentiation 34 (CD34). The mean patient age was 68.2 years (range, 44-81 years); the male-to-female ratio was 6:10; lesion sites at upper (U), middle (M) and lower regions (L) of the stomach were 9/6/1; and the average tumor diameter was 28.3 mm. The mean surgical time was 271 min and the surgical time became progressively faster with each successive surgery. There were 12 and four patients with mitotic counts of <5 and 5-10, respectively, which was significantly different (P=0.01). Immunohistochemical stains showed that tumors from 13 and 10 patients (81.2 and 62.5%, respectively) were positive for KIT and CD34, respectively (P=0.328). All resected surgical margins were negative. According to Fletcher's risk classification, there were five, eight and three patients at an 'extremely low', 'low', and 'intermediate' risk (31.2, 50 and 18.8%, respectively) (P=0.003). The mean postoperative hospital duration was 12.3 days (range, 10-15 days). In conclusion, an ultra-minimally invasive surgery-hybrid EFTR is a safe and established surgical endoscopy procedure.

Abstract
BACKGROUND Endoscopic full-thickness resection (EFTR) requires a reliable full-thickness suturing device and an endoscopic counter-traction device to prevent the collapse of the digestive tract. OBJECTIVE The present study aimed to assess the reliability of newly developed flexible endoscopy suturing devices and the feasibility of pure EFTR. METHODS A total of 30 EFTRs were performed and allocated to three groups (N = 10 for each group). The full-thickness sutures were placed using over-the-scope clips (OTSCs), hand-sewn sutures, or the Double-arm-bar Suturing System (DBSS). Air leak tests were conducted in the three groups. The times required for the placement of one OTSC suture and single-stitch simple interrupted sutures (hand-sewn and DBSS sutures, respectively) were also compared. RESULTS All 30 full-thickness sutures were completely and successfully placed. Regarding the air leak tests, the Mann-Whitney U test showed significant differences between OTSC and hand-sewn sutures (p = 0.003). There was also a significant difference between OTSC and DBSS sutures (p = 0.023). There was no significant difference between hand-sewn and DBSS sutures (p = 0.542). A significant difference was found in the suture time for single-stitch simple interrupted sutures among the OTSC, hand-sewn, and DBSS sutures. The Mann-Whitney U test revealed a significant difference between OTSC and hand-sewn sutures (p = 0.0001). There was no significant difference between OTSC and DBSS sutures (p = 0.533), while a significant difference was found between hand-sewn and DBSS sutures (p = 0.0001). CONCLUSIONS Pure EFTR is feasible if the mechanical counter traction system is used to expand a small operative field and DBSS is used to make full-thickness sutures. The high safety of full-thickness resection and full-thickness suturing allows for clinical applications of this method.

Abstract
AIM: To investigate the feasibility and safety of Natural orifice trans-umbilical endoscopic cholecystectomy with a water-jet hybrid-knife in a non-survival porcine model.
METHODS: Pure natural orifice transluminal endoscopic surgery (NOTES) cholecystectomy was performed on three non-survival pigs, by transumbilical approach, using a water-jet hybrid-knife. Under general anesthesia, the following steps detailed the procedure: (1) incision of the umbilicus followed by the passage of a double-channel flexible endsocope through an overtube into the peritoneal cavity; (2) establishment of pneumoperitoneum; (3) abdominal exploration; (4) endoscopic cholecystectomy: dissection of the gallbladder performed using water jet equipment, ligation of the cystic artery and duct conducted using nylon loops; and (5) necropsy with macroscopic evaluation.
RESULTS: Transumbilical endoscopic cholecystectomy was successfully completed in the first and third pig, with minor bleedings. The dissection times were 137 and 42 min, respectively. The total operation times were 167 and 69 min, respectively. And the lengths of resected specimen were 6.5 and 6.1 cm, respectively. Instillation of the fluid into the gallbladder bed produced edematous, distended tissue making separation safe and easy. Reliable ligation using double nylon loops insured the safety of cutting between the loops. There were no intraoperative complications or hemodynamic instability. Uncontrolled introperative bleeding occurred in the second case, leading to the operation failure.
CONCLUSION: Pure NOTES trans-umbilical cholecystectomy with a water-jet hybrid-knife appears to be feasible and safe. Further investigation of this technique with long-term follow-up in animals is needed to confirm the preliminary observation.

Abstract
BACKGROUND No reliable pure natural orifice transluminal endoscopic surgery (NOTES) mechanical counter traction (MCT) device for the flexible endoscope to obtain a sufficient surgical endoscopic field has yet been developed. Our experience with 10 cases of hybrid NOTES prompted the realization of the importance of an MCT device for the flexible endoscope and inspired us to establish innovative noninsufflation endoscopic full-thickness resection (EFTR) with an MCT device. METHODS We performed 40 EFTR 40 mm in diameter on excised whole porcine stomachs. Twenty were resected by an MCT device to obtain a surgical field (MCT group), and another 20 were resected with a conventional endoscopic attachment (control group). We evaluated the successful resection rates of EFTR and procedure times between two groups. Next, we implemented EFTR with a custom prototype MCT device in three cases of stomach pseudotumors in female dogs. Gastric pseudotumors ~40 mm in diameter were marked within the open surgical field created by the MCT device. After resecting the pseudotumors, we conducted full-thickness suturing using over-the-scope clips. RESULTS In the MCT group, all 20 cases were completely resected. On the other hand, in the control group, only 8 cases were performed via EFTR (P < 0.01). The mean ± standard deviation EFTR procedure times for the MCT and control groups were 4.13 ± 0.824 and 36.26 ± 8.67 min, respectively (P = 0.001). In three dogs, sufficient surgical working spaces were obtained up to 78 mm (range, 65-78 mm), and full-thickness resections were performed safely and sutured with over-the-scope clips. CONCLUSIONS Our new prototype MCT device effectively obtains a sufficient surgical endoscopic field during EFTR. We are developing a new MCT with a bending function to perform EFTR in any location in the stomach.
