Several randomized controlled trials and meta-analyses have confirmed the advantages of laparoscopic surgery in early gastric cancer, and there are indications that this may also apply in advanced distal gastric cancer. The study objective was to evaluate the safety and effectiveness of laparoscopic gastrectomy (LG), in comparison to open gastrectomy (OG), in the management of locally advanced gastric cancer. The single-center, case–control study included 204 patients, in conveyance sampling, who underwent radical gastrectomy for locally advanced gastric cancer. Out of 204 patients, 102 underwent LG, and 102 patients underwent OG. The primary endpoints were safety endpoints, i.e., complication rates, reoperation rates, and 30-day mortality rates. The secondary endpoints were efficacy endpoints, including perioperative characteristics and oncological outcomes. Even though the overall complication rate was higher in the OG group compared to the LG group (30.4% and 19.6%, respectively), the difference between groups did not reach statistical significance (p = 0.075). No significant difference was identified in reoperation rates and 30-day mortality rates. Time spent in the intensive care unit (ICU) and overall hospital stay were shorter in the LG group compared to the OG group (p < 0.001). Although the number of retrieved lymph nodes is oncologically adequate in both groups, the median number is higher in the OG group (35 vs. 29; p = 0.024). Resection margins came out to be negative in 92% of patients in the LG group and 73.1% in the OG group (p < 0.001). The study demonstrated statistically longer survival rates for the patients in the laparoscopic group, which particularly applies to patients in the most prevalent, third stage of the disease. When patients with the Clavien–Dindo grade ≥II were excluded from the survival analysis, further divergence of survival curves was observed. In conclusion, LG can be safely performed in patients with locally advanced gastric cancer and accomplish the oncological standard with short ICU and overall hospital stay. Since postoperative complications could affect overall treatment results and diminish and blur the positive effect of the minimally invasive approach, further clinical investigations should be focused on the patients with no surgical complications and on clinical practice to cut down the prevalence of complications.

Inflammatory myofibroblastic tumor has been defined as a histologically distinctive lesion with uncertain behaviour. The term inflammatory myofibroblastic tumor more commonly referred to as " pseudostumor " , denotes a pseudosarcomatous inflammatory lesion that contains spindle cells, myofibroblasts, plasma cells, lymphocytes and histiocytes. It exhibits a variable biological behavior that ranges from frequently benign lesions to more aggressive variants. Inflammatory myofibroblastic tumor mostly occurs in the soft tissue of children and young adults, and the lungs are the most commonly affected site, but it has been recognized that any anatomic localization can be involved. Inflammatory myofibroblastic tumors in adults are very rare, especially in the stomach. We present a case of a 43-year old woman with primary inflammatory myofibiroblastic tumor in the stomach and a review of the literature. © 2013 Bjelovic et al.; licensee BioMed Central Ltd.

Background: The global shift from open esophagectomy (OE) to minimally invasive esophagectomy (MIE) for treating esophageal cancer is well-established. Recent data indicate that transitioning from hybrid minimally invasive esophagectomy (hMIE) to total minimally invasive esophagectomy (tMIE) can be challenging due to concerns about higher leakage rates and lower lymph node counts, especially at the beginning of the learning curve. This study aimed to demonstrate that a safe transition from OE to tMIE for cancer is possible using process management methodology. Methods: A step-change approach was adopted in process management planning, with hMIE serving as an intermediate step between OE and tMIE. This single-center, case–control study included 150 patients who underwent the Ivor Lewis procedure with curative intent for esophageal cancer. Among these patients, 50 underwent OE, 50 hMIE (laparoscopic procedure followed by conventional right thoracotomy), and 50 tMIE (laparoscopic and thoracoscopic approach). A preceptored training scheme was implemented during execution, and treatment results were monitored and controlled to ensure a safe transition. Results: During the transition, the tMIE group was not worse than the hMIE and OE groups regarding operation duration (p = 0.135), overall postoperative complications (p = 0.020), anastomotic leakage rates (p = 0.773), 30-day mortality (p = 1.0), and oncological outcomes (based on R status (p = 0.628) and 2-year survival (p = 0.967)). Additionally, the tMIE group showed superior results in terms of major postoperative pulmonary complications (p = 0.004) and ICU stay duration (p < 0.001). Conclusions: Utilizing managerial methodology and practice in surgery, as a bridge between interdisciplinary and transdisciplinary approaches, demonstrated that transitioning from OE to tMIE, with hMIE as an intermediate step, is safe and feasible without compromising outcomes. © 2024 by the authors.

Background: Even though there is no consensus, many authors believe that in the cases of large hiatal defects, structurally altered crura and/or absence of peritoneal lining, a crural reinforcement should be performed. Reinforcement could be performed with different techniques and different type of mesh, either synthetic or biologic. The disadvantages of mesh repair include the possibility of serious complications and increased costs especially in the usage of composite or biologic mesh. Methods: The study includes 10 cases of reinforced primary suture line of the pillars with autologous fascia lata, in elective laparoscopic repair of the giant PEH with a large hiatal defect and friable crura. After intraopreative confirmation of the large hiatal defect (hiatal surface area of more than 8 cm2) and friable crura, an autologous fascia lata graft was harvested in the usual manner and placed in on-lay fashion to reinforce the pillar suture line. We analyzed surgical technique, complications, and initial follow-up of the patients. Results: Average hiatal surface area (HSA) in our series was 10.6 cm2 (range 8.1 to 14.4 cm2). The average duration of operation was 203.9 min/3.4 hours (range 160-250 min). Except for a mild hematoma in the harvesting region that resolved spontaneously, there were no procedure related complications and 30 days mortality rate was zero. The average postoperative length of stay was 6.5 days (5-8 days). Out of 10 patients, 5 completed the annual follow-up visit, while 8 completed a 6- month follow-up visit. So far there is no hernia recurrence and/or problems with swallowing function. However, one patient has felt a mild discomfort in the harvested region that does not influence normal daily activities. Conclusions: Autologous fascia lata graft hiatal reinforcement represents a technically feasible, easy, and available option for the on-lay reinforcement of large hiatal defects with friable crura in the laparoscopic repair of giant PEHs. © 2015 Bjelovic et al.; licensee BioMed Central.
