Purpose: This study assessed the feasibility of near-infrared (NIR) imaging with indocyanine green (ICG) in investigating the completeness of laparoscopic lymph node (LN) dissection for gastric cancer. Materials and Methods: Patients scheduled for laparoscopic gastrectomy for treating gastric cancer were enrolled in the study. After intraoperative submucosal ICG injection (0.05 mg/mL), LN dissection was performed under conventional laparoscopic light. After dissection, the LN stations of interest were examined under the NIR mode to locate any extra ICG-stained (E) tissues, which were excised and sent for pathologic confirmation. This technique was tested in 2 steps: infra-pyloric LN dissection (step 1) and review of all stations after proper radical node dissection (step 2). Results: In step 1, 15 patients who underwent laparoscopic pylorus-preserving gastrectomy (LPPG) and 15 patients who underwent laparoscopic distal gastrectomy (LDG) were examined. Seven and 2 E-tissues were obtained during LPPG and LDG, respectively. From the retrieved E-tissues, 1 and 0 tissue obtained during LPPG and LDG, respectively, was confirmed as LN. In step 2, 20 patients were enrolled (13 D1+ dissection and 7 D2 dissection). Six E-tissues were retrieved from 5 patients, and 1 tissue was confirmed as LN in the pathologic review. Overall, 15 E-tissues were detected and removed, and 2 tissues were confirmed as LNs in the pathologic review. Both nodes were from LN station #6, with 1 case each in the LDG and LPPG groups. Conclusions: NIR imaging may provide additional node detection during laparoscopic LN dissection for gastric cancer, especially in the infra-pyloric area.

Purpose: The use of laparoscopic surgery for gastric disease has been gaining popularity. However, there has been the controversy over the indications and the standard techniques of laparoscopic gastric surgery in the early gastric cancer (EGC). The purposes of this study were to compare the clinical outcomes among a hand-assisted laparoscopic distal gastrectomy (HALDG), a laparoscopy-assisted distal gastrectomy (LADG), and an open distal gastrectomy (ODG) and to discuss the role of these procedures in the treatment of EGC. Materials and Methods: Between August 2001 and July 2004, laparoscopic surgery was performed in our institution on 25 patients, LADG (n=7) and HALDG (n=18) with EGC. Analysis was performed on clinical data such as the operative time, the hospital stay, the start of oral intake, and the number of harvested lymph nodes. Patients were categorized into early and late groups by using the date of surgery and were also grouped by surgical procedure. To evaluate the feasibility and efficacy of laparoscopic surgery for EGC, we compared the clinical data with those for ODGs performed during the same period. Results: There was no difference in the number of harvested lymph nodes between the laparoscopic group and the open group, but the operation time in the laparoscopic group was longer than that in the open group (P<0.05). Also, no significant differences in other clinical data were found between the two groups. Comparing the early and the late periods of the series, the number of harvested lymph nodes for a HALDS increased from $22.31\pm4.29\;to\;29.40\pm3.21$ (P<0.05). Conclusion: Our early experience with laparoscopic gastric surgery shows that a wide range of possibilities exist for applying laparoscopic gastric surgery to selected gastric cancer patients. However, the surgical procedure should be standardized, and the outcomes of laparoscopic surgery, in comparison to those of open surgery, need to be confirmed based on a large randomized study.

Inflammatory myofibroblastic tumors (IMTs) of the stomach are extremely rare in adults, and their oncologic prognosis is not well understood. We present a 28-year-old man with a proximal gastric IMT. The patient visited the emergency department of Yeouido St. Mary's Hospital with syncope and hematemesis. Hemoglobin levels were <5.5 g/dl. Gastric fibroscopy showed a protruding mass $4{\times}4cm$ in size, with central ulceration on the posterior wall of the fundus and diffuse wall thickening throughout the cardia and anterior wall of the upper body. Endoscopic biopsy revealed indeterminate spindle cells, along with inflammation. Given the risk of rebleeding, an operation was performed despite the uncertain diagnosis. Because the mass was circumferential, laparoscopic proximal gastrectomy and double-tract anastomosis were performed to ensure a safe resection margin. The pathological diagnosis was consistent with an IMT originating from the stomach, although the tumor was negative for anaplastic lymphoma kinase gene mutation.

Totally laparoscopic distal gastrectomy (TLDG) frequently involves the use of delta shaped gastroduodenostomy (DSG) for intracorporeal anastomosis. However, DSG has some drawbacks, and the book binding technique (BBT) was developed as a new technique to overcome these drawbacks. Subsequently, this technique was further improved with the development of modified book binding technique (MBBT). This study evaluated the safety and feasibility of MBBT in patients undergoing TLDG. Thirty-three patients who underwent TLDG with MBBT were retrospectively evaluated. The mean operation time was $277.6{\pm}37.1minutes$, including $51.9{\pm}15.7minutes$ for reconstruction. Two patients had anastomosis-related complications, one patient with stricture after leakage and 1 patient with stenosis. The former patient was treated with endoscopic balloon dilatation, and the latter was managed conservatively; neither required re-operation. MBBT is a safe and feasible technique, with acceptable surgical outcomes. It may be a good alternative option for the treatment of intracorporeal anastomosis in patients undergoing TLDG.

Purpose: The perigastric vagus nerve may play an important role in preserving function after gastrectomy, and intraoperative neurophysiologic tests might represent a feasible method of evaluating the vagus nerve. The purpose of this study is to assess the feasibility of neurophysiologic evaluations of the function and viability of perigastric vagus nerve branches during gastrectomy. Materials and Methods: Thirteen patients (1 open total gastrectomy, 1 laparoscopic total gastrectomy, and 11 laparoscopic distal gastrectomy) were prospectively enrolled. The hepatic and celiac branches of the vagus nerve were exposed, and grabbing type stimulation electrodes were applied as follows: 10-30 mA intensity, 4 trains, $1,000{\mu}s/train$, and $5{\times}$frequency. Visible myocontractile movement and electrical signals were monitored via needle probes before and after gastrectomy. Gastrointestinal symptoms were evaluated preoperatively and postoperatively at 3 weeks and 3 months, respectively. Results: Responses were observed after stimulating the celiac branch in 10, 9, 10, and 6 patients in the antrum, pylorus, duodenum, and proximal jejunum, respectively. Ten patients responded to hepatic branch stimulation at the duodenum. After vagus-preserving distal gastrectomy, 2 patients lost responses to the celiac branch at the duodenum and jejunum (1 each), and 1 patient lost response to the hepatic branch at the duodenum. Significant procedure-related complications and meaningful postoperative diarrhea were not observed. Conclusions: Intraoperative neurophysiologic testing seems to be a feasible methodology for monitoring the perigastric vagus nerves. Innervation of the duodenum via the celiac branch and postoperative preservation of the function of the vagus nerves were confirmed in most patients.
The Information Committee of the Korean Gastric Cancer Association sent questionnaires to 31 laparoscopic gastric surgeons about their personal experiences with laparoscopic gastric surgery from 2001 to 2003. Twenty-four surgeons responded to the questionnaires (response rate: $77.4\%$).The number of laparoscopic gastric surgeries from 2001 to 2003 was 1,130 and increased from 209 in 2001 to 593 in 2003. The number of operations for a gastric adenocarcinoma also increased from 87 cases in 2001 to 403 cases in 2003. Laparoscopic radical procedures, such as a laparoscopyassisted distal gastrectomy or total gastrectomy (LADG or LATG), have increased rapidly during this period. (55 cases in 2001, 150 cases in 2002, and 364 cases in 2003). Laparoscopic function-preserving gastrectomies were not performed until 2003, during which year one pylorus- preserving gastrectomy and six proximal gastrectomies were performed laparoscopically. A wedge resection for a gastric submucosal tumor was performed in 71 cases in 2001, 82 in 2002, and 103 in 2003. Hand-assisted laparoscopic surgery (HALS) was performed in 39 cases in 2001, 55 in 2002, and 49 in 2003. As for personal indications for a LADG, 14 surgeons performed a LADG only for a T1 lesion, and 5 surgeons extended their indications to T2N0 lesions. In the near future, laparoscopic procedures for gastric cancer will be widely adopted in Korea if the medical-insurance obstacle is overcome and the long-term survival results are verified.
Purpose: In Korea, the number of laparoscopy-assisted distal gastrectomies for early gastric cancer patients has been on the increase. Although minimally invasive surgery is more beneficial, no reported case of a total laparoscopic gastrectomy has been reported because of difficulty with intracorporeal anastomosis. This study attempts, through our experience, to determine the safety and feasibility of a total laparoscopic gastrectomy with various types of intracorporeal anastomosis using laparoscopic linears stapler in treating early gastric carcinomas. Materials and Methods: We investigated the surgical results and clinicopatholgical characteristics of 81 patients that underwent a totally laparoscopic distal gastrectomy at our department between June 2004 and May 2007. The intracorporeal anastomoses were performed by using laparoscopic linear staplers. Results: The mean operative time was 287 minutes, the mean anastomotic time was 40 minutes, and the mean number of laparoscopic linear staplers used for an operation was 7.5. The mean time to the first flatus, the first food intake, and discharge from hospital was 2.9, 3.6, and 10.3 days respectively. There were 11 cases of postoperative complications, but no case of postoperative mortality or conversion to an open procedure. In 75 patients with an adenocarcinoma, the mean number of lymph nodes harvested was 38.1 and the stage distribution was as follows: stage I, 72 patients; stage II, 2 patients; stage IV, 1 patient. During the mean follow-up period of 14 months, 5 patients died of other causes and there were no cases of cancer recurrence. Conclusion: A total laparoscopic gastrectomy with intracorporeal anastomosis by using a laparoscopic linear stapler was found to be safe and feasible. We were able to obtain acceptable surgical outcomes in terms of minimal invasiveness.
The frequency of anastomotic leakage after gastrectomy is reported to be 0.9~8%. To reduce deleterious outcomes of anastomotic leakage, we devised the "Omental Free-shaped Flap Reinforcement On Anastomosis and Dissected area" procedure not only to prevent fatal complications following anastomotic leakage but also to promote vascularity of anastomoses and other expected oncological benefits. This video illustrates the surgical procedure following a totally laparoscopic distal gastrectomy. After completion of the anastomosis, the remaining omentum was mobilized upward and divided into two sections. We placed the left section of the omental flap under the anastomosis between the stomach and pancreas. Finally, we grasped and curved the tip of the section to cover the anastomosis from behind, and we placed the right section of the omental flap above the anastomosis. These two sections were approximated with clips to the anterior wall of the stomach. The patient was discharged without complications.

Purpose: This study aimed to compare the long-term functional and patient-reported outcomes between intra-corporeal delta-shaped gastroduodenostomy and gastrojejunostomy after laparoscopic distal gastrectomy for gastric cancer. Materials and Methods: We retrospectively reviewed clinicopathological data from 616 patients who had undergone laparoscopic distal gastrectomy for stage I gastric cancer between January 2015 and September 2020. Among them, 232 patients who had undergone delta-shaped anastomosis and another 232 who had undergone Billroth II anastomosis were matched using propensity scores. Confounding variables included age, sex, body mass index, physical status classification, tumor location, and T classification. Postoperative complications, nutritional outcomes, endoscopic findings, and quality of life (QoL) were compared between the 2 groups. Results: No significant differences in postoperative complications or nutritional parameters between the two groups were observed. Annual endoscopic findings revealed more residual food and less bile reflux in the delta group (P<0.001) than in the Billroth II group. Changes of QoL were significantly different regarding emotional function, insomnia, diarrhea, reflux symptoms, and dry mouth (P=0.007, P=0.002, P=0.013, P=0.001, and P=0.03, respectively). Among them, the delta group had worse insomnia, reflux symptoms, and dry mouth within three months postoperatively. Conclusions: Long-term nutritional outcomes and QoL were comparable between the delta and Billroth II groups. However, more residual food and worse short-term QoL regarding insomnia, reflux symptoms, and dry mouth were observed in the delta group. Longer fasting time before endoscopic evaluation and short-term symptom management would have been helpful for the delta group.
Purpose: Intra-abdominal infection is a common postoperative complication of laparoscopic pylorus-preserving gastrectomies (PPGs). Many studies have reported that intra-abdominal infectious complications after gastrectomy adversely affect patient survival outcomes. To prevent gastric fluid leakage into the abdominal cavity, we developed a novel anastomosis method in which the stomach lumen is not opened (termed the non-opened clean end-to-end anastomosis method [NoCEAM]) and evaluated its feasibility. Materials and Methods: Subsequent to lymphadenectomy, the oral and anal resection lines were sutured using an intraoperative endoscope. After closing the stomach circumferentially with clips, the specimen was rolled outward like a "donut." We resected the specimen circumferentially using a linear stapler, and anastomosis was completed simultaneously. We examined the feasibility of this procedure ex vivo, using three porcine stomachs, and in vivo, using one pig. Subsequently, we applied the procedure to 13 consecutive patients with middle-third early gastric cancer utilizing laparotomic, laparoscopic, and robotic PPG. Results: NoCEAM was completed in all porcine models and human cases. In the human cases, the mean operation time (±standard deviation) was 279±51 minutes, and mean blood loss volume was 22±45 mL. The mean number of linear staples used was 5.06±0.76. None of the patients had complications, and all were discharged on the eighth postoperative. The serum total protein, serum albumin, and hemoglobin levels did not change significantly after surgery. Conclusions: NoCEAM is feasible and safe for performing totally laparoscopic or robotic PPG. It may reduce postoperative complications, such as intra-abdominal infections.
