Review
The prevalence of obesity is rising, becoming a medical problem worldwide. Also GERD incidence is higher in obese patients compared with normal weight, with an increased risk of 2.5 of developing symptoms and erosive esophagitis. Different treatment modalities have been proposed to treat obese patients, but bariatric surgery due to its complex interactions via anatomic, physiologic and neurohormonal changes achieved the best long-term results, with sustained weight loss and decrease of complications and mortality caused by obesity. The bariatric surgical procedures can be restrictive: laparoscopic adjustable gastric band (LAGB) and laparoscopic sleeve gastrectomy (LSG), or malabsorptive-restrictive such as Roux-en-Y gastric bypass (RYGB). These surgical procedures may influence esophageal motility and lead to esophageal complications like gastroesophageal reflux disease (GERD) and erosive esophagitis. From the literature we know that the RYGB can ameliorate GERD symptoms, and some bariatric procedures were finally converted to RYGB because of refractory reflux symptoms. For LAGB the results are good at the beginning, but some patients experienced new reflux symptoms in the follow-up period. Recently LSG has become more popular than other complex bariatric procedures, but some follow-up studies report a high risk of GERD after it. This article reviews the results published after LSG regarding gastroesophageal reflux and the mechanisms responsible for GERD in morbidly obese subjects.

Review
Anastomotic leakage (AL) constitutes a prominent cause of significant morbidity following gastrectomy for gastric cancer. The manifestation of AL typically occurs within 7 to 10 days post-surgery, with reported incidence rates of 5.8-6.7% for open gastrectomy and 3.3-4.1% for laparoscopic gastrectomy. Various predisposing risk factors have been identified, including the individual nutritional status (excluding obesity) and preoperative corticotherapy. Interestingly, the administration of neoadjuvant therapies appears to reduce the AL occurrence. In the context of distal gastrectomies, the rates of AL are comparable between laparoscopic, robotic, and open approaches. The total gastrectomies have higher AL rate compared to distal gastrectomies, which are considered the preferred approach. Prophylactic drainage measures have not demonstrated efficacy in preventing AL. As for postoperative management, conservative treatment is indicated for patients presenting with mild clinical symptoms and increased inflammatory blood tests. This approach involves fasting, enteral or parenteral nutrition, administration of antibiotics, and percutaneous drainage. For small AL, endoscopic therapies such as stents, vacuum therapy, clips, suturing devices, and injections are appropriate treatment options. In cases of high-volume fistulas, severe sepsis or failure of previous therapies, surgical reoperation becomes the ultimate solution.

Comparative Study Review
Robot-assisted gastrectomy has been reported to be a safe alternative to both conventional laparoscopy and the open approach for treating early gastric carcinoma. Currently, there are a limited number of published reports on this technique in the literature. We assessed the current status of robotic and laparoscopic surgery in the treatment of gastric cancer and compared the operative outcomes, learning curves, and oncological outcome of the two approaches. Robotic gastrectomy offers benefits that include increased ease of performing D2 lymph node dissection and reduced blood loss compared with laparoscopic gastrectomy. However, the operative time is longer, and robotic gastrectomy is more costly for the patients. Regarding to the operative and oncological outcomes, there appears to be no significant differences between laparoscopic and robotic gastrectomies after the surgeon overcomes the associated learning curves. Sharing the available knowledge regarding laparoscopic and robotic gastrectomies could shorten these learning curves. For elder patients, minimally invasive surgery that decreases the postoperative recovery time should be considered the preferred treatment. Prospective randomized studies are required to compare the surgical and oncological outcomes among laparoscopic, robotic, and open surgeries for both early and advanced gastric cancer.

Review
Over the past 30 years, the prevalence of upper third gastric cancer (GC) and gastroesophageal junction (GEJ) cancer has increased. Total gastrectomy with D2 lymph node dissection is the standard surgical treatment for non-early (T2 or higher) upper third and GEJ cancers, but total gastrectomy often results in post-gastrectomy syndrome (5-50%), consisting of weight loss, dumping syndrome, and anemia. Proximal gastrectomy (PG) has the potential to avoid these postoperative problems by preserving stomach function. However, PG has historically been discouraged by surgeons owing to the high incidence of postoperative reflux esophagitis (20-65%), anastomotic stenosis, and decreased quality of life. In recent years, anti-reflux reconstruction techniques, such as the double flap technique and double-tract reconstruction, have been developed to be performed after PG, and evidence has emerged that these techniques not only reduce the incidence of postoperative reflux esophagitis but also decrease postoperative weight loss and prevent anemia. Prospective studies are underway to determine whether PG with anti-reflux techniques improves patient-reported quality of life. In the present work, we reviewed available evidence for the use of PG for GC and GEJ cancer, including oncologically appropriate patient selection for PG, potential functional benefits of PG over TG, and various types of reconstructions that can be performed after PG, as well as future research on the use of PG.

Review
Surgery used to be the only therapy for gastric cancer, and since its ability to cure gastric cancer was the focus of attention, less attention was paid to function-preserving surgery in gastric cancer, though it was studied for gastroduodenal ulcer. Maki et al developed pylorus-preserving gastrectomy for gastric ulcer in 1967. At the same time, the definition of early gastric cancer (EGC) was being considered, histopathological investigations of EGC were carried out, and the validity of modified surgery was sustained. After the development of H2-blockers, the number of operations for gastroduodenal ulcers decreased, and the number of EGC patients increased simultaneously. As a result, the indications for pylorus-preserving gastrectomy for EGC in the middle third of the stomach extended, and various alterations were added. Since then, many kinds of function-preserving gastrectomies have been performed and studied in other fields of gastric cancer, and proximal gastrectomy, jejunal pouch interposition, segmental gastrectomy, and local resection have been performed. On the other hand, from the overall perspective, it can be said that endoscopic resection, which was launched at almost the same time, is the ultimate function-preserving surgery under the current circumstances. The current function-preserving gastrectomies that are often performed and studied are pylorus-preserving gastrectomy and proximal gastrectomy. The reasons for this are that these procedures that can be performed with systemic lymph node dissection, and they include three important elements: (1) reduction of the extent of gastrectomy; (2) preservation of the pylorus; and (3) preservation of the vagal nerve. In addition, these operations are more likely to be performed with a laparoscopic approach as minimally invasive surgery. Of the above-mentioned three elements, reduction of the extent of gastrectomy is the most important in our view. Therefore, we should try to reduce the extent of gastrectomy if curability of the gastric cancer can still be achieved. However, if we preserve a wider residual stomach in function-preserving gastrectomy, we should pay attention to the development of metachronous gastric cancer.

Review
Metabolic and bariatric surgery is the most effective therapy for weight loss and improving obesity-related comorbidities, comprising the Roux-en-Y gastric bypass (RYGB), gastric banding, sleeve gastrectomy (SG), and biliopancreatic diversion with duodenal switch. While the effectiveness of weight loss surgery is well-rooted in existing literature, weight recurrence (WR) following bariatric surgery is a concern. Endoscopic bariatric therapy presents an anatomy-preserving and minimally invasive option for managing WR in select cases. In this review article, we will highlight the endoscopic management techniques for WR for the most commonly performed bariatric surgeries in the United States -RYGB and SG. For each endoscopic technique, we will review weight loss outcomes in the short and mid-terms and discuss safety and known adverse events. While there are multiple endoscopic options to help address anatomical issues, patients should be managed in a multidisciplinary approach to address anatomical, nutritional, psychological, and social factors contributing to WR.

Review
Although a steady decline in the incidence and mortality rates of gastric carcinoma has been observed in the last century worldwide, the absolute number of new cases/year is increasing because of the aging of the population. So far, surgical resection with curative intent has been the only treatment providing hope for cure; therefore, gastric cancer surgery has become a specialized field in digestive surgery. Gastrectomy with lymph node (LN) dissection for cancer patients remains a challenging procedure which requires skilled, well-trained surgeons who are very familiar with the fast-evolving oncological principles of gastric cancer surgery. As a matter of fact, the extent of gastric resection and LN dissection depends on the size of the disease and gastric cancer surgery has become a patient and "disease-tailored" surgery, ranging from endoscopic resection to laparoscopic assisted gastrectomy and conventional extended multivisceral resections. LN metastases are the most important prognostic factor in patients that undergo curative resection. LN dissection remains the most challenging part of the operation due to the location of LN stations around major retroperitoneal vessels and adjacent organs, which are not routinely included in the resected specimen and need to be preserved in order to avoid dangerous intra- and postoperative complications. Hence, the surgeon is the most important non-TMN prognostic factor in gastric cancer. Subtotal gastrectomy is the treatment of choice for middle and distal-third gastric cancer as it provides similar survival rates and better functional outcome compared to total gastrectomy, especially in early-stage disease with favorable prognosis. Nonetheless, the resection range for middle-third gastric cancer cases and the extent of LN dissection at early stages remains controversial. Due to the necessity of a more extended procedure at advanced stages and the trend for more conservative treatments in early gastric cancer, the indication for conventional subtotal gastrectomy depends on multiple variables. This review aims to clarify and define the actual landmarks of this procedure and the role it plays compared to the whole range of new and old treatment methods.

Meta-Analysis Review
OBJECTIVE
Laparoscopic distal gastrectomy (LDG) with adequate lymph node dissection for gastric cancer is increasingly being applied worldwide. Several randomized trials have been conducted regarding this surgical approach. The aim of this meta-analysis is to present an updated overview comparing laparoscopic distal gastrectomy and open distal gastrectomy (ODG) with regard to short-term results, long-term follow-up, and oncological outcomes.
METHODS
An extensive search was conducted using the Medline, Embase, and Cochrane databases, including randomized clinical trials comparing LDG and open distal gastrectomy. Studies were assessed regarding outcomes for operative results, postoperative recovery, complications, mortality, adequacy of resection, and long-term survival.
RESULTS
In total, 2,347 articles were identified, and 22 randomized clinical trials were selected for analysis. Operative results showed significantly less blood loss and a longer operative time for LDG. Patients after LDG showed a faster recovery of bowel function, shorter hospitalization, and fewer complications, while mortality rates did not differ. Lymph node yield and resection margins were similar in both groups. Results regarding survival could not be analyzed due to a great diversity in follow-up duration.
CONCLUSION
Laparoscopic distal gastrectomy shows favorable outcomes, such as less perioperative blood loss, faster patient recovery, and fewer complications. Moreover, LDG is oncologically adequate regarding lymph node yield, adequacy of resection, and survival.

Observational Study
The usefulness, safety and oncological validity of laparoscopic gastrectomy (LG) for remnant gastric cancer (RGC) have not been widely reported.A total of 38 patients who underwent gastrectomy for RGC were enrolled at Wakayama Medical University Hospital between April 2008 and December 2018. All consecutive patients were included in this retrospective study; the patients were divided into the open gastrectomy group and the laparoscopic group according to the sequential nature of their operation. Fifteen patients underwent open gastrectomy for RGC (OGR) between April 2008 and December 2013, and 23 patients underwent LG for RGC (LGR) after 2014.In the OGR group, all initial operations were performed by open surgery, whereas in the LGR group, 11 patients (47%) initially underwent laparoscopic surgery and 12 patients (53%) initially underwent open surgery (P = .002), 3 patients of which (25%) converted to open gastrectomy. There was no significant difference in the number of lymph node dissections or in operative time between the 2 groups, but blood loss was significantly lower in the LGR group than that in the OGR group (P = .002). Furthermore, although there was no difference between the 2 groups in C-reactive protein value on postoperative day 1, C-reactive protein value on postoperative day 3 was significantly lower in the LGR group than in the OGR group (P = .012). There were no differences in postoperative complications or long-term outcomes, including recurrence-free survival and overall survival.LGy is suitable in cases in which the initial surgery is performed by laparoscopic surgery. Even if the initial surgery is open surgery, it is oncologically equivalent to open gastrectomy and can be performed safely with less blood loss.

Review
Laparoscopic sleeve gastrectomy is one of the most common bariatric procedures worldwide. It has recently gained in popularity because of a low complication rate, satisfactory resolution of comorbidities, and excellent weight loss outcome. This article reviews the surgical technique, expected postsurgical imaging appearance, and imaging findings of common complications after laparoscopic sleeve gastrectomy. Understanding of the surgical technique of laparoscopic sleeve gastrectomy and of the normal postsurgical anatomy allows accurate interpretation of imaging findings in cases of insufficient weight loss, weight regain, and postsurgical complications.
