Purpose: This study aimed to compare the surgical and oncological outcomes between totally laparoscopic pylorus-preserving gastrectomy (TLPPG) with intracorporeal anastomosis and laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) with extracorporeal anastomosis. Materials and Methods: A retrospective analysis was performed in 258 patients with cT1N0 gastric cancer who underwent laparoscopic pylorus-preserving gastrectomy using two different anastomosis methods: TLPPG with intracorporeal anastomosis (n=88) and LAPPG with extracorporeal anastomosis (n=170). The following variables were compared between the two groups to assess the postoperative surgical and oncological outcomes: proximal and distal margins, number of resected lymph nodes (LNs) in total and in LN station 6, operation time, postoperative hospital stay, and postoperative morbidity including delayed gastric emptying (DGE). Results: The average length of the proximal margin was similar between the TLPPG and LAPPG groups (2.35 vs. 2.73 cm, P=0.070). Although the distal margin was significantly shorter in the TLPPG group than in the LAPPG group (3.15 vs. 4.08 cm, P=0.001), no proximal or distal resection margin-positive cases were reported in either group. The average number of resected LN was similar in both groups (36.0 vs. 33.98, P=0.229; LN station 6, 5.72 vs. 5.33, P=0.399). The operation time was shorter in the TLPPG group than in the LAPPG (200.17 vs. 220.80 minutes, P=0.001). No significant differences were observed between the two groups in terms of postoperative hospital stay (9.38 vs. 10.10 days, P=0.426) and surgical complication rate (19.3% vs. 22.9%), including DGE (8.0% vs. 11.8%, P=0.343). Conclusions: The oncological safety and postoperative complications of TLPPG with intracorporeal anastomosis are similar to those of LAPPG with extracorporeal anastomosis.

Purpose: This study aimed to examine the effects of 4 main types of gastrectomy for proximal gastric cancer on postoperative symptoms, living status, and quality of life (QOL) using the Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45). Materials and Methods: We surveyed 1,685 patients with upper one-third gastric cancer who underwent total gastrectomy (TG; n=1,020), proximal gastrectomy (PG; n=518), TG with jejunal pouch reconstruction (TGJP; n=93), or small remnant distal gastrectomy (SRDG; n=54). The 19 main outcome measures (MOMs) of the PGSAS-45 were compared using the analysis of means (ANOM), and the general QOL score was calculated for each gastrectomy type. Results: Patients who underwent TG experienced the lowest postoperative QOL. ANOM showed that 10 MOMs were worse in patients with TG. Four MOMs improved in patients with PG, while 1 worsened. One MOM was improved in patients with TGJP versus 8 MOMs in patients with SRDG. The general QOL scores were as follows: SRDG (+39 points), TGJP (+6 points), PG (+3 points), and TG (-1 point). Conclusions: The TG group experienced the greatest decline in postoperative QOL. SRDG and PG, which preserve part of the stomach without compromising curability, and TGJP, which is used when TG is required, enhance the postoperative QOL of patients with proximal gastric cancer. When selecting the optimal gastrectomy method, it is essential to understand the characteristics of each and actively incorporate guidance to improve postoperative QOL.

목적: 조기위암 수술에 복강경 적용의 용이성 및 종양학적 안정성에 대해서는 많은 연구가 아루어지고 있으나, 복 강경 적용의 또 다른 목적인 '삶와 질' 향상에 대한 연구 는 아직 미흡한 현실이다. 이에 저자들은 위암 수술에 복강경 적용이 '삶의 질' 향상에 미치는 장기적 영향을 평가 하고자 본 연구를 고안하였다. 대상 및 방법: 2003년 1월부터 2004년 12월까지만 2년간 순천향대학병원 외과에서 위 절제 수술 후 위암 1기로 진단된 154명의 환자들을 대상으로 수술 후 1년 이상 경과한 시점에서 설문조사를 시행하였다. EORTC OLQ-C30(3판)과 EORTC QLQ-ST022 한글판을 이용하여 한 명의 전문 간호사에 의해 외래 방문 시 직접 면담 혹은 전화 상담을 통해 설문조사를 시행했으며, 통계처리는 SPSS 12.0 for Windows를 이용하였다. 결과: 전체 대상 환자 154명 중 86명에서 설문 조사가 이루어져 58%의 응답률을 보였으며, 86명(개복군: 57명, 복강경군: 29명)의 평균 연령은 55세였고, 남자가 60명 여자가 26명으로 남녀 비는 2.3 : 1 이었다. 개복 군의 종양 크기는 평균 2.42 cm로 복강경군의 평균 종양 크기 1.8 cm에 비해 유의하게 크기가 컸으며(P=0.003), 평균 획득 림프절 수도 개복 군에서 36개로 유의하게 더 많았다(P=0.000). 그 외 종양관련 인자인 원발암와 침윤도, 림프절 전이 및 TNM 병기에 있어서 양 군 간에 차이는 없었다. 전반적인 건강 상태와 관련된 2 항목의 평균 점수는 개복 군이 57 (${\pm}20.6$), 복강경 군이 60.3 (${\pm}20.4$)으로 양 군 간에 유의한 차이는 없었으며, 기능과 관련된 15 항목과 증상과 관련된 13항목에 있어서도 양군 간에 유의한 차이는 없었다. EORTC QLQ-STO22를 이용한 '삶의 질' 비교 결과 개복군의 평균 점수는 94.5 (${\pm}97.3$), 복강경군은 68.9 (${\pm}64.9$)로 개복군에서 전반적으로 불편한 증상을 많이 호소하였으나 통계학적인 차이는 없었다. 결론: EORTC QLQ-C30 (3판)과 EORTC QLQ-STO22 한글판을 이용한 설문조사 결과 장기적인 측면에서 위 절제술에 복 강경 적용이 환자의 '삶의 질' 향상에 영향을 미치지 못했다.

Recently, we experienced two advanced gastric cancer (AGC) patients younger than 17 years of age. The first case was a 15-year, 2-month-old male who had suffered from epigastric soreness for 5 weeks. His grandfather died of gastric cancer at 39 years of age. Under the diagnosis of AGC, he underwent a total gastrectomy with D2 lymph node dissection. There was no evidence of distant metastasis. Pathologic examination revealed a 4.5$\times$4 cm, signet ring cell adenocarcinoma with subserosal invasion and with metastasis in 9 of 42 regional lymph nodes (T2bN2M0). The second case was a 17-year, 11-month-old male who had suffered from epigastric pain for 2 years without familial clustering. Under the diagnosis of AGC, he underwent a distal subtotal gastrectomy with D2 lymph node dissection. There was no evidence of distant metastasis. Pathologic examination revealed a 3$\times$2 cm, signet ring cell adenocarcinoma with subserosal invasion and with metastasis in 9 of 45 regional lymph nodes (T2bN2M0). The two patients have been alive without recurrence for 27 months and 4 months, respectively. Even among teenagers, patients with abdominal complaints should be subjected to a thorough examination of the gastrointestinal tract.

Purpose: This study aimed to examine the early postprandial changes in gastrointestinal (GI) hormones and hemodynamics in terms of early dumping syndrome after gastrectomy for gastric cancer. Materials and Methods: Forty patients who underwent gastrectomy for gastric cancer and 18 controls without previous abdominal surgery were enrolled. Before and 20 minutes after liquid meal ingestion, blood glucose, glucagon-like peptide-1 (GLP-1), and GLP-2 concentrations and superior mesenteric artery (SMA) and renal blood flow were measured. The patients' heart rates were recorded at 5-minute intervals. All subjects were examined for dumping syndrome using a questionnaire based on Sigstad's clinical diagnostic index. Results: The postprandial increases in blood glucose, GLP-1, and GLP-2 levels as well as SMA blood flow and heart rate were greater in patients who underwent gastrectomy than in controls (all P<0.010). Patients who underwent gastrectomy showed a significantly decreased renal blood flow (P<0.001). Among patients who underwent gastrectomy, distal gastrectomy was a significant clinical factor associated with a lower risk of early dumping syndrome than total gastrectomy (hazard ratio, 0.092; 95% confidence interval, 0.013-0.649; P=0.017). Patients who underwent total gastrectomy showed a greater postprandial increase in blood glucose (P<0.001), GLP-1 (P=0.030), and GLP-2 (P=0.002) levels as well as and heart rate (P=0.013) compared to those who underwent distal gastrectomy. Conclusions: Early postprandial changes in GI hormones and hemodynamics were greater in patients who underwent gastrectomy than in controls, especially after total gastrectomy, suggesting that these changes play a crucial role in the pathophysiology of early dumping syndrome.

목적: 복강경하 보조 위 절제술이 위암 치료에 사용되기 위해서는 기술적인 측면 외에 수술적 치료와 관계하는 영양학적 및 면역학적 요소가 함께 고려되어야 한다. 이에 본 연구에서는 조기위암 환자에서 복강경하 위아전절제술의 영양학적 및 면역학적 측면에서의 안정성에 대해 알아 보고자 본 연구를 시행하였다. 대상 및 방법: 2006년 4월부터 2009년 5월까지 조기위암으로 복강경하 위아전절제술을 시행한 87예와 개복 위아전절제술을 시행한 30명의 환자를 대상으로 임상 정보와 혈청학적 검사를 후향적으로 비교 분석하였다. 결과: 두 군 간의 술 전 임상병리학적 요인에는 차이가 없었으며, 복강경하 위아전절제술군에서 총 백혈구수는 개복군에 비해 술 후 1일째와 3일째 더 증가 정도가 낮았으며(P=0.001, P=0.008), CRP는 술 후 1일째와 3일째에서 증가 정도의 차이를 보이지 않았으나(P=0.632, P=0.139), 술 후 5일째의 감소 정도는 통계학적 차이를 보였다(P<0.001). T4/T8 ratio는 복강경하 위아전절제술군에서 술 후 3일째 감소 정도가 적었으나(P=0.003), Albumin의 감소 정도는 통계학적 차이를 보이지 않았다(P=0.157). 결론: 복강경 위아전절제술은 개복 위절제술에 비해 Albumin을 이용해 비교한 영양학적 측면에서 장점은 없었으나, 술 후 총 백혈수의 증가, CRP 감소, 및 T4/T8 ratio 감소 등의 전신 면역 및 염증 반응에서 우월함을 알 수 있었다.

Purpose: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) risk calculator is useful in predicting postoperative adverse events. However, its accuracy in specific disorders is unclear. We validated the ACS NSQIP risk calculator in patients with gastric cancer undergoing curative laparoscopic surgery. Materials and Methods: We included 207 consecutive early gastric cancer patients who underwent laparoscopic gastrectomy between January 2018 and January 2019. The preoperative characteristics and risks of the patients were reviewed and entered into the ACS NSQIP calculator. The estimated risks of postoperative outcomes were compared with the observed outcomes using C-statistics and Brier scores. Results: Most of the patients underwent distal gastrectomy with Roux-en-Y reconstruction (74.4%). We did not observe any cases of mortality, venous thromboembolism, urinary tract infection, renal failure, or cardiac complications. The other outcomes assessed were complications such as pneumonia, surgical site infections, any complications requiring re-operation or hospital readmission, the rates of discharge to nursing homes/rehabilitation centers, and the length of stay. All C-statistics were <0 and the highest was for pneumonia (0.65; 95% confidence interval: 0.58-0.71). Brier scores ranged from 0.01 for pneumonia to 0.155 for other complications. Overall, the risk calculator was inconsistent in predicting the outcomes. Conclusions: The ACS NSQIP surgical risk calculator showed low predictive ability for postoperative adverse events after laparoscopic gastrectomy for patients with early gastric cancer. Further research to adjust the risk calculator for these patients may improve its predictive ability.

Purpose: The aim of this study is to investigate the clinical factors affecting on the cure rate by invasive and open surgery for gastric cancer and to establish a subgroup of patients who can be applied by the early recovery after surgery program through this retrospective analysis. Materials and Methods: In this retrospective study, we analyzed 425 patients who underwent gastric cancer surgery between January 2011 and December 2011 and were managed with conventional clinical therapies. This clinical algorithm was made when the patient was in minimally invasive surgery group and discharged from hospital one day faster than them in open surgery group. Results: The completion rate of the clinical pathway was 62.4%. Despite the different applications of clinical pathway, completion rate in minimally invasive surgery group was significantly higher than that of open group (P<0.001). In multivariate analysis, the surgical procedure of minimally invasive surgery (odds ratio=4.281) was the most predictable factor to complete clinical pathway. Additionally, younger patients (odds ratio=1.933) who underwent distal gastrectomy (odds ratio=1.999) without combined resection (odds ratio=3.069) were predicted to accomplish the clinical pathway without any modifications. Conclusions: We concluded that high efficacy of the clinical pathway for gastric cancer surgery was expected to selected patients through retrospective analysis (expected completion rate=85.4%). In addition, these patients would become enrolled criteria for early recovery program in gastric cancer surgery.

A 67 year old male at a regular checkup underwent esophagogastroduodenoscopy. On performing esophagogastroduodenoscopy, a lesion about 1.2 cm depressed was noted at the gastric angle. The pathology of the biopsy specimen revealed a well-differentiated adenocarcinoma. On performing an abdominal computed tomography (CT) scan & positron emission tomography-computed tomography (PET-CT) scan, no definite evidence of gastric wall thickening or mass lesion was found. However, lymph node enlargement was found in the left gastric and prepancreatic spaces. This patient underwent laparoscopic assisted distal gastrectomy and D2 lymph node dissection. On final examination, it was found out that the tumor had invaded the mucosal layer. The lymph node was a metastasized large cell neuroendocrine carcinoma with an unknown primary site. The patient refused chemotherapy. He opted to undergo a close followup. At the postoperative month 27, he had a focal hypermetabolic lesion in the left lobe of the liver that suggested metastasis on PET-CT scan. He refused to undergo an operation. He underwent a radiofrequency ablation.

We report the case of a patient with gastric adenocarcinoma with multiple liver metastases. This patient showed complete remission for more than 68 months after S-1/cisplatin combination chemotherapy and radical total gastrectomy. The patient, a 63-year-old man, presented with dyspepsia and difficulty in swallowing. Endoscopic findings showed a huge ulcero-infiltrative mass at the lesser curvature of the mid-body, extending to the distal esophagus. Biopsy revealed a poorly differentiated tubular adenocarcinoma. An abdominal computed tomography scan demonstrated multiple hepatic metastases. S-1/cisplatin combination chemotherapy was initiated, and following completion of six cycles of chemotherapy, the gastric masses and hepatic metastatic lesions had disappeared on abdominal computed tomography. Radical total gastrectomy and D2 lymphadenectomy combined with splenectomy were performed. The patient underwent three cycles of S-1/cisplatin combination chemotherapy followed by tegafur-uracil therapy for 1 year. He remained in complete remission for more than 68 months after surgery.
