RESUMEN
BACKGROUND: This study aimed to investigate the short- and long-term outcomes of laparoscopic gastrectomy (LG) in patients with advanced gastric cancer following neoadjuvant chemotherapy (NAC) to determine its safety and feasibility. METHODS: We retrospectively investigated 51 patients who underwent gastrectomy for locally advanced gastric cancer [cT3-4/N1-3 or macroscopic type 3 (> 80 mm) or type 4] following NAC between November 2009 and January 2018. After excluding two patients who underwent palliative surgery due to peritoneal dissemination, 49 patients were ultimately selected for this cohort study. The patients were then divided into the LG group and open gastrectomy (OG) group, after which the clinicopathological characteristics as well as short- and long-term outcomes were examined. RESULTS: Compared with the OG group, the LG group demonstrated a significantly lower amount of intraoperative blood loss and a shorter hospital stay. The overall complication rates were 10% (2 of 20 patients) and 24% (7 of 29 patients) in the LG and OG groups (P = 0.277), respectively. No significant differences in 5-year disease-free (LG 44.4% vs. OG 53.3%; P = 0.382) or overall survival rates (LG 46.9% vs. OG 54.0%; P = 0.422) were observed between the groups. Multivariate analysis revealed that the surgical procedure (LG vs. OG) was not an independent risk factor for disease-free (P = 0.645) or overall survival (P = 0.489). CONCLUSIONS: LG may be a potential therapeutic option for patients with gastric cancer following NAC considering its high success rates and acceptable short- and long-term outcomes.

OBJECTIVE: This study aimed to compare the short-term surgical outcomes and cost-benefits following totally laparoscopic distal gastrectomy (TLDG) and laparoscopy-assisted distal gastrectomy (LADG) for the treatment of gastric cancer. METHODS: Between April 2007 and December 2013, a total of 100 patients with gastric cancer underwent laparoscopic distal gastrectomy. The patients were classified into two groups according to whether intracorporeal anastomosis or extracorporeal anastomosis had been performed. The comparison between the groups was based on clinicopathological characteristics and surgical and economic outcomes. RESULTS: There were 57 and 43 patients who underwent TLDG and LADG, respectively. The patients' demographics and tumor characteristics did not show any statistically significant differences with the exception for tumor location. In the LADG group, tumors were localized to relatively higher positions (p = 0.024) and received Roux-en-Y reconstruction more frequently (p < 0.001). There were no differences in the incidence of morbidity. Anastomotic leakage was not recorded in either group, although anastomotic stenosis occurred in one patient (1.8 %) after TLDG and in two patients (4.7 %) after LADG. Compared with the LADG group, the TLDG group was associated with significantly less operative blood loss (p < 0.001), a shorter time to oral intake (p = 0.012), and hospital stay (p = 0.018). The median operation costs were greater in the TLDG group than in the LADG group (¥982,000 in TLDG vs. ¥879,830 in LADG; p < 0.001), whereas the median total hospital costs were similar between the two groups (¥1302,665 in LADG vs. ¥1383,322 in TLDG: p = 0.119). CONCLUSION: This study suggests that TLDG is as technically feasible, safe, and effective as LADG for treating patients with gastric cancer. Furthermore, TLDG is associated with equivalent total hospital costs compared with LADG. The increased operation cost is offset by the decreased costs associated with longer periods of hospitalization.

BACKGROUND: This study aimed to investigate the short-term surgical outcomes of laparoscopic gastrectomy for gastric cancer in elderly patients in order to determine the safety, feasibility, and risk factors for postoperative complications associated with this procedure. METHODS: We retrospectively investigated 208 patients who underwent laparoscopic gastrectomy for gastric cancer between January 2007 and September 2014. After excluding 15 patients with unusual medical histories or surgical treatments, 193 were selected for this cohort study. We divided the patients into two cohorts: elderly patients (≥75 years old) and non-elderly patients (<74 years old). We compared these cohorts with respect to clinicopathological characteristics and intraoperative and postoperative parameters. RESULTS: The overall complication rates were 11.4% (8 of 70 patients) in the elderly cohort and 8.1% (10 of 123 patients) in the non-elderly cohort (P = 0.449). In a univariate analysis, Charlson comorbidity index (CCI) of ≥3, American Society of Anesthesiologists (ASA) score of 3, operative time of ≥330 min, and intraoperative blood loss of ≥50 ml were found to correlate significantly with postoperative complications. In a multivariate analysis, CCI of ≥3 (P = 0.034), ASA score of 3 (P = 0.019), and intraoperative blood loss of ≥50 ml (P = 0.016) were found to be independent risk factors of postoperative complications. In contrast, age was not found to significantly affect the risk of postoperative complications. CONCLUSIONS: Laparoscopic gastrectomy for gastric cancer can be successfully performed in elderly patients with an acceptable complication rate. This study suggested that high CCI, ASA score, and intraoperative blood loss volume were identified as independent predictors of postoperative complications after laparoscopic gastrectomy for gastric cancer.

OBJECTIVE: Suprapancreatic lymph node dissection is critical for gastric cancer surgery. Beginning in 2010, a medial approach was adopted for suprapancreatic lymph node dissection during laparoscopic gastrectomy for distal gastric cancer in our institution. The aim of this study was to compare surgical outcomes of the medial approach and conventional approach in laparoscopic gastric surgery. METHODS: Between January 2007 and December 2012, a total of 100 patients with clinical T1 or T2 tumors underwent laparoscopic distal gastrectomy involving suprapancreatic lymph node dissection by the medial approach (n = 44) and conventional approach (n = 56) with curative intent. The comparison was based on clinicopathological characteristics and surgical outcome. RESULTS: The laparoscopic procedure was not converted to laparotomy in any patient. The patients' demographics and tumor characteristics did not show any statistically significant difference, except for tumor location. In the conventional approach group, the tumors were at a higher position (p = 0.037) and more frequently received Roux-en-Y reconstruction (p < 0.001). Intracorporeal anastomosis was significantly more common in the medial approach group (p < 0.001). Compared with the conventional approach, the medial approach was associated with significantly less operative blood loss (p < 0.001), more retrieved suprapancreatic lymph nodes (p = 0.019), and a shorter hospital stay (p = 0.018). The rates of complications were comparable between the two groups. CONCLUSION: This study suggests that the medial approach to suprapancreatic lymph node dissection seems to be convenient and useful in laparoscopic gastric cancer surgery.

BACKGROUND: The oncologic safety and feasibility of laparoscopic D2 gastrectomy for advanced gastric cancer are still uncertain. The aim of this study is to compare our results for laparoscopic D2 gastrectomy with those for open D2 gastrectomy. METHODS: Between 1998 and 2008, a total of 336 patients with clinical T2, T3, or T4 tumors underwent laparoscopic (n = 186) or open (n = 150) gastrectomy involving D2 lymph node dissection with curative intent. To produce this study population, 123 patients in the open group who matched those of the laparoscopic group with regard to age, sex, body mass index (BMI), American Society of Anesthesiologists (ASA) score, tumor location, and clinical tumor stage were retrospectively selected. The short- and long-term outcomes of these patients were examined. RESULTS: Laparoscopic D2 gastrectomy was associated with significantly less operative blood loss and shorter hospital stay, but longer operative time, compared with open D2 gastrectomy. The mortality and morbidity rates of the laparoscopic group were comparable to those of the open group (1.1 % vs. 0, P = 0.519, and 24.2 % vs. 28.5 %, P = 0.402). The 5-year disease-free and overall survival rates were 65.8 and 68.1 % in the laparoscopic group and 62.0 and 63.7 % in the open group (P = 0.737 and P = 0.968). There were no differences in the patterns of recurrence between the two groups. CONCLUSIONS: This study suggests that laparoscopic D2 gastrectomy provides reasonable oncologic outcomes with acceptable morbidity and low mortality rates. Although operation time is currently long, this approach is associated with several advantages of laparoscopic surgery, including quick recovery of bowel function and short hospital stay. Laparoscopic D2 gastrectomy may offer a favorable alternative to open D2 gastrectomy for patients with advanced gastric cancer.

BACKGROUND: In patients having carcinoma in the remnant stomach, total resection of the remnant stomach with lymph node dissection is a prerequisite. MATERIALS AND METHODS: We present the first series of successful totally laparoscopic complete gastrectomy (TLCG) for gastric remnant cancer. RESULTS: TLCG was successfully performed without adverse events during surgery in five patients with gastric remnant cancer. The median age of the patients was 72 years (range, 56-84 years), and there were three men and two women. Three of them had a Billroth I reconstruction and two had a Billroth II reconstruction, and in four cases following partial gastrectomy for gastric cancer and one for gastroduodenal ulcer. The median operative time was 360 min; blood loss was 20 ml. The median number of retrieved lymph nodes was 19. No complications occurred postoperatively, and all of the patients were discharged within the ninth postoperative day. CONCLUSIONS: Although TLCG for gastric remnant cancer is a technically difficult and challenging operation that requires careful lysis of adhesion and dissection along the major vessels, as well as intracorporeal anastomosis, this procedure is technically feasible. Long-term follow-up is mandatory to validate oncological outcome.

INTRODUCTION: 8K ultra-high-definition (UHD) images enabling clearer recognition of anatomical structures could contribute to further development of surgical techniques and advanced applications in endoscopic surgery fields. This study aimed to clarify effects and challenges of endoscopic surgery with 8K UHD endoscopy compared to existing endoscopy systems. METHODS: In this multicenter, cross-sectional, questionnaire survey, data were collected from surgical participants who newly used and observed 8K UHD endoscopy in patients undergoing surgery from February 2020 to February 2021. Survey items included sense of presence, reality, depth perception, visibility of tissue, eyestrain, and degree of satisfaction for operators and observers, and weight, operability, focus adjustment, physical fatigue, eyestrain, and satisfaction for camera assistants. Participants rated each 8K UHD endoscopic surgery on a one-to-five scale (definitively inferior, relatively inferior, equivalent, relatively superior, definitively superior) compared to the existing endoscopy system of each facility. RESULTS: Overall, questionnaire responses from 139 participants assessing 8K UHD endoscopic surgery were collected from surgeries performed in 46 patients. Respective ratings of operators and observers included sense of presence: "superior or relatively superior", 97.8% and 91.5%; reality: "superior or relatively superior", 76.1% and 72.3%; and visibility of tissue: "superior or relatively superior", 93.5% and 87.2%. Weight was rated as "inferior or relatively inferior" by 73.9% of camera assistants and focus adjustment as "inferior" by 60.9% of them. CONCLUSIONS: 8K UHD endoscopic surgery enabled identification of surgical anatomies more clearly, provided a sense of presence and reality, and might improve educational effect. Technological development is expected to reduce the burden of camera assistants.

Nutritional deficiency is an inevitable consequence after total gastrectomy. We have recently developed a simple technique for nutritional support after total gastrectomy, in which the button jejunostomy is conducted on the afferent limb for long-term jejunal feeding. The purpose of this study was to evaluate the safety and efficacy of the low-profile button jejunostomy (LBJ) in patients with gastric malignancy. The records of 55 consecutive patients who were treated by total gastrectomy along with LBJ-making for gastric malignancy were prospectively reviewed and analyzed. Outcome parameters such as body weight, per cent ideal body weight (IBW), and nutritional parameters were regularly measured preoperatively and postoperatively. There were no complications related to LBJ. Among the patients, 53 who had survived at least 6 months after surgery were evaluated. The median caloric supplement by enteral feeding at home was 800 kcal per day. The median weight loss was 10.7 per cent of initial body weight. More than half of the patients achieved IBW and 40 patients (75%) were classified as low or no risk of malnutrition. This technique is easy to perform with minimal discomfort, and we believe that LBJ is useful for supporting dietary intake and for preventing malnutrition after total gastrectomy.

BACKGROUND: The purpose of this study was to evaluate the long-lasting influence of laparoscopic training during residency course on outcomes of laparoscopic cholecystectomy (LC). MATERIALS AND METHODS: We compared outcomes of LC in patients treated by surgeons who have learned LC by the traditional surgical residency program (traditional group; n = 15) with those of LC operated on by surgeons who received additional intensive laboratory training in their residency [Jikei Surgical Skill Training Program (JSTP) group; n = 9]. RESULTS: Among the 503 patients subjected to LC, 302 (60.0%) cases were performed by surgeons in the traditional group and 201 (40.0%) cases in the JSTP group. The patient characteristics, operative outcome variables, and the pathological findings of the gallbladder were comparable in the two groups. Despite no difference in the above factors, conversion rates were significantly higher in the traditional group compared with the JSTP group (10.6% vs 5.0%; p = 0.026). In multivariate analysis, training background was an independent risk factor for conversion to open surgery (odds ratio, 2.79; 95% confidence interval, 1.25-6.24). CONCLUSIONS: To ensure competence for laparoscopic skills, we propose that such training program should be integrated into the curriculum of the general surgery residency.

BACKGROUND: In patients having locally advanced cancer of the stomach with suspected tumor infiltration to the pancreatic head or the duodenum, a concurrent pancreaticoduodenectomy with gastrectomy is occasionally prerequisite to achieve a microscopically tumor-free surgical margin. MATERIALS AND METHODS: We present the first series of successful totally laparoscopic pancreaticoduodenectomy (TLPD) for advanced gastric cancer with suspected infiltration to the pancreatic head. RESULTS: TLPD was successfully performed without adverse events during surgery and resulted in favorable short-term outcomes of three patients with locally advanced gastric cancer with suspected invasion to the pancreas. CONCLUSIONS: Although TLPD for locally advanced gastric cancer is a technically difficult challenging operation that requires careful dissection along the major vessels, intracorporeal tie sutures, and the placement of an external drainage tube into a narrow pancreatic duct, this procedure is technically feasible and safe in the hands of experienced surgeons. Long-term follow-up is mandatory to validate oncological outcome.

Laparoscopic surgery is less invasive and allows faster recovery from surgery and reduces postoperative recurrence of adhesions and small bowel obstruction (SBO). However, as much as 30% of patients require repeated treatment for the recurrence of SBO owing to formation of adhesions. To reduce such a complication, we developed a new method on the basis of the use of antiadhesive membrane during laparoscopic surgery. This study included 8 consecutive patients for whom laparoscopic surgery was performed, and antiadhesive membrane was placed intraperitoneally over the wound areas using our new technique. After the median follow-up period of over 3 years, recurrence of SBO has not been observed in any of the patients. Laparoscopic surgery requires advanced surgical skills, including the placement of antiadhesive membrane. Our "Seprafilm flag" technique is simple and easy to employ during laparoscopic surgery that allows prevention of postoperative formation of adhesions.

We report two patients with suture line recurrence in the jejunal pouch after curative proximal gastrectomy for gastric cancer. The first patient was a 60-year-old asymptomatic woman with gastric cancer (T2N0M0) after curative proximal gastrectomy with jejunal pouch interposition. She had to undergo a second resection for suture line recurrence in the jejunal pouch 12 months later. On examination of the resected specimen, histological examination revealed a moderately differentiated adenocarcinoma, which was similar to that of the primary tumor. The second patient was a 74-year-old man who was also diagnosed as having locoregional recurrences in the jejunal pouch after a curative proximal gastrectomy with an S-shaped pouch for gastric cancer (T2N0M0). Histological examination of the resected specimen revealed moderately differentiated adenocarcinoma, which had a similar histopathology to that of the primary tumor. During the first procedure, the jejunal pouch was formed using several disposable devices and the end-to-side esophagojejunostomy was performed with another circular stapler to avoid contamination through surgical instruments. Exfoliated cancer cells that may have detached from the primary tumor during the surgical procedures could have contributed to local recurrence along the longitudinal suture line of the pouch.

BACKGROUND: Retraction of the liver is necessary to ensure an adequate working space in laparoscopic surgery, but the retraction force applied may cause transient liver dysfunction. We have introduced the technique using a Penrose drain to suspend the liver with the performance of laparoscopic gastrectomy for gastric adenocarcinoma. METHODS: 111 patients with gastric adenocarcinoma underwent laparoscopic gastrectomy using either a Penrose drain (n = 47) or a Nathanson's retractor (n = 64) for displacement of the liver. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, alkaline phosphatase (ALP) and albumin were compared among the groups at baseline, immediately after operation, and on postoperative days (POD) 1, 2, 3, 5, and 7. RESULTS: The levels of ALT on POD 2, 3, and 5 were significant higher in the Nathanson's retractor group than in the Penrose drain group. Levels of AST on POD 2 and 3 were also higher in the Nathanson's retractor group than in the Penrose drain group. There was no significant difference in total bilirubin, ALP, and serum albumin levels between groups. CONCLUSIONS: The use of the Penrose drain for retraction of the liver appears to attenuate postoperative liver dysfunction during laparoscopic gastrectomy for gastric adenocarcinoma.

OBJECTIVE: To evaluate the safety and effectiveness of laparoscopic total gastrectomy with D2 lymphadenectomy for gastric cancer. DESIGN: Review of findings from a prospectively acquired institutional database. SETTING: University hospital. PATIENTS: Fifty-five consecutive patients operated on by the same surgeon between October 1997 and March 2008. MAIN OUTCOME MEASURES: Blood loss, complication rate, and survival. RESULTS: All operations were accomplished without conversion to open laparotomy. The median operative time was 406 minutes. The median blood loss was 102 mL. A median of 46 lymph nodes were harvested. The TNM stages of the tumor were I in 17 patients (31%), II in 12 (22%), III in 16 (29%), and IV in 10 (18%). A total of 21 complications occurred in 18 patients (33%) with no postoperative mortality. At last follow-up, 44 of the 55 patients were alive without tumor recurrence and 3 with recurrence at a median follow-up of 16 months, whereas 8 had died of recurrence or another cause. CONCLUSIONS: The mortality rate of zero and acceptable morbidity of our series indicate that laparoscopic total gastrectomy with D2 lymphadenectomy is technically feasible and safe in the hands of experienced surgeons. Long-term follow-up is mandatory to validate oncologic outcome.

We report a patient with a minute gastric carcinoid tumor with lymph node metastasis, and a small gastric cancer. A 50-year-old man having a diagnosis of an elevated lesion on the anterior wall of the gastric body, detected by a series of upper gastrointestinal examinations, was referred to the Cancer Institute Hospital. Careful upper fluoroscopy disclosed a small superficial depressed lesion with converging folds and a superficial elevated lesion covered with nonspecific gastric mucosa. With a final preoperative diagnosis of depressed early cancer and minute carcinoid tumor of the stomach, made by upper gastrointestinal examinations including biopsy, the patient underwent segmental gastrectomy and perigastric lymph node dissection. Histological examination of the resected specimen revealed a lymph node metastasis from a gastric carcinoid tumor of 5-mm diameter, in addition to an early gastric cancer of poorly differentiated adenocarcinoma. Small gastric carcinoid tumors have been regarded as being benign neoplasms biologically. However, the case we present suggests that attention should be paid to the possibility of metastasis at the time of treatment for a minute sporadic gastric carcinoid tumor. We therefore discuss the malignant potential of these tumors, mainly from the viewpoint of histopathological classification, to gain understanding so that the patients can be treated adequately.
