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(p T1 a and p T1b) 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 wallinversion 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.展开更多

Clinical data related to patient characteristics and surgical outcomes were collected from medical records. The parameters for assessing the safety of the procedure included operative time, volume of blood loss, achievement of the critical view of safety, use of additional trocars, conversion to laparotomy, intraoperative and postoperative complications, and duration of postoperative hospital stay. Patient backgrounds were statistically compared between those with and without conversion to laparotomy.RESULTS: A total of 100 patients underwent SILC for acute cholecystitis during the period. Preoperative endoscopic treatment was performed for suspected choledocholithiasis in 41 patients(41%). The mean time from onset of acute cholecystitis was 7.7 d. According to the Updated Tokyo Guidelines(TG13) for the severity of cholecystitis, 86 and 14 patients had grade Ⅰ and grade Ⅱ acute cholecystitis, respectively. The mean operative time was 87.4 min. The mean estimated blood loss was 80.6 mL. The critical view of safety was obtained in 89 patients(89%). Conversion laparotomy was performed in 12 patients(12%). Postoperative complications of Clavien-Dindo grade Ⅲ or greater were observed in 4 patients(4%). The mean duration of postoperative hospital stay was 5.7 d. Patients converted from SILC to laparotomy tended to have higher days after onset.CONCLUSION: SILC is feasible for acute cholecystitis; in addition, early surgical intervention may reduce the risk of laparotomy conversion.展开更多

The subjects were divided into the ERAS program group and the conventional control group. The clinical characteristics, recovery variables, and complications of patients were analyzed.RESULTS: The time to first ambulation, oral food intake, and time to defecation were significantly shorter in the ERAS group(n = 30), compared to the conventional group(n = 31; P = 0.04, 0.003, and 0.01, respectively). The postoperative hospital stay was less in the ERAS group(6.8 ± 1.1 d) compared to the conventional group(7.7 ± 1.1 d)(P = 0.002). There was no significant difference in postoperative complications between the ERAS(1/30) and conventional care groups(2/31)(P = 1.00). There were no readmissions or mortality during the 30-d follow-up period.CONCLUSION: The ERAS program is associated with a shorter hospital stay in gastric cancer patients undergoing laparoscopic radical gastrectomy. The ERAS protocol is useful in the treatment of gastric cancer.展开更多

In the Thoracic department of the Republican Research Oncological Centre of the Republic of Uzbekistan during the period from 2004 to 2008 in the plan of investigation of the patients with esophageal and stomach cancer including roentgenoscopy and (or) roentgenography of the thoracic chest, contrast esophageal and stomach roentgenoscopy, EPGDS and ultrasonography of the mediastinal and abdominal cavity organs additionally computed tomography and diagnostic thoraco-and (or) laparoscopy were included. The cancer of mesothoracic esophageal part with invasion into the upper thoracic part was diagnosed in 2 patients, the cancer of mesothoracic esophageal part-in 12 patients, the cancer of the middle and the lower parts-in 7 patients, the cancer the lower thorax part-in 7 patients, the cardioesophageal cancer-in 9 patients, a total cancer of a stomach with affection of the bottom third of the oesophagus-in 1 patient. Thoracoscopy and laparoscopy allow determination of the respectability of the tumorous process in the esophageal and stomach cancer considerably lowering the number of exploratory thoracotomies and laparotomies.展开更多

The gold standard of care for gallbladder calculi and isolated common bile duct stones is represented by laparoscopic cholecystectomy and endoscopic retrograde cholangiopancreatography, respectively, while a debate still exists regarding how to treat the two diseases at the same time. Many therapeutic options are also available when the two conditions are associated, including many different types of treatment, which local professionals often administer. The need to limit maximum discomfort and risks for the patients, combined with the economic pressure of reducing costs and utilizing resources, favors single-step procedures. However, a multitude of data fail to strongly demonstrate the superiority of any technique(including a two or multi-step approach), while rigorous clinical trials that include so many different types of treatment are still lacking, and it is most likely unrealistic to conduct them in the future. Therefore, the choice of the best management is often led by the local presence of professional expertise and resources, rather than by a real superiority of one strategy over another.展开更多

In an attempt to reduce the invasiveness of the procedure, surgeons have developed single-incision laparoscopic cholecystectomy(SILC), minilaparoscopic cholecystectomy(MLC) and natural orifice transluminal endoscopic surgery(NOTES). The aim of this review was to determine the role of these new minimally invasive approaches for elective laparoscopic cholecystectomy in the treatment of gallstone related disease. Current literature remains insufficient for the correct assessment of emerging techniques for laparoscopic cholecystectomy. None of these procedures has demonstrated clear benefits over conventional laparoscopic cholecystectomy. SILC cannot be currently recommended as it can be associated with an increased risk of bile duct injury and incisional hernia incidence. NOTES cholecystectomy is still experimental, although hybrid transvaginal cholecystectomy is gaining popularity in clinical practice. As it is standardized and almost identical to the standard laparoscopic technique, MLC could lead to limited benefits without exposing patients to increased postoperative complications, being therefore adoptable for routine elective cholecystectomy. Technical challenges of SILC and NOTES cholecystectomy could be addressed with the evolution of new surgical tools that need to catch up with the innovative minds of surgeons. Regardless the place of these approaches in the future, robotization may be necessary to impose them as standard treatment.展开更多
