  • In this study, the Korean Gastric Cancer Association collected 12,152 gastric cancer patients (5,380 in 1995, 6,772 in 1999) from 29 hospitals. Twelve clinicopathological factorssex, age, operation date, tumor location, size, operation method, gross type of early gastric cancer, Borrmann type, depth of invasion, lymph node metastasis, distant metastasis, stage-were summarized in a database file and analyzed. Chronological change has been evaluated between the patients in 1995 and those in 1999. Proportion of early gastric cancer has been increased from $28.6\%$ in 1995 to $32.8\%$ in 1999. The UICC staging was $25.3\%$ (1995), $29.3\%$ (1999) for stage Ia, $12.7\%,\;13.9\%$, for stage Ib, $15.7\%,\;14.8\%$, for stage II, $15.2\%,\;13.2\%$, for stage IIIa, $8.2\%,\;6.3\%$, for stage IIIb, and $20.1\%,\;18.1\%$, for stage IV. The operation of each year was subtotal gastrectomy ($67.6\%,\;67.3\%$), total gastrectomy ($26.6\%,\;24.1\%$), proximalgastrectomy ($0.3\%,\;3.6\%$), wedge resection ($0.1\%,\;0.5\%$), bypass surgery ($2.3\%,\;1.8\%$), and open biopsy ($3.1\%,\;2.7\%$). In early gastric cancer, type IIc was the most common ($44.5\%$ in 1995, $42.8\%$ in 1999). The incidence of upper one-third cancer was slightly increased in 1999 ($12.5\%$) than 1995 ($11.2\%$), which is reflected in the increased prox-imal gastrectomy in 1999 (207 cases, $3.6\%$). There was no significant difference between either groups regarding the regional differences.

  • 목적: 소화성 궤양의 급만성 합병증으로 대표되는 천공, 출혈, 협착의 수술적 치료에서 Helicobacter pylori (H. pylori) 제균요법과 proton pump inhibitor의 도입, 중재적 내시경 치료와 같은 비수술적 치료의 발달로 천공, 출혈 등의 급성기 합병증의 수술은 점차 감소되고 있다. 그러나 내과적 소화성 궤양의 협착, 폐색에 대한 비수술적 치료의 결과는 만족스럽지 못한 상태로 수술의 역할이 중요하다. 이에 저자들은 만성 소화성 궤양으로 위출구 폐색을 동반한 환자들의 수술적 치료 후 임상결과를 분석하고자 하였다. 대상 및 방법: 1994년 1월부터 2007년 12월까지 국립의료원 외과에서 소화성 궤양 폐색으로 수술한 31명의 환자를 후향적으로 분석하였고, 이전의 궤양 수술로 인한 유착성 폐색 및 천공이나 출혈로 인한 응급수술시 발견된 폐색동반의 예는 제외하였다. 각 임상병리학적 결과를 수술방법에 따라 우회수술군과 절제수술군으로 분류하였고, 수술결과의 평가는 Visick score를 이용하였다. 수술 후 재발의 기준은 소화성 궤양의 임상증상이 나타나 내시경으로 확진된 경우만을 포함하였다. 결과: 우회수술군이 6명(19.4%), 절제수술군이 25명(80.6%)이었다. 평균 연령은 57.5세(25~81세)이었고, 남자 29명(93.5%), 여자 2명(6.5%)이었다. 평균 증상 지속기간 29.6개월이었고, 흡연자가 19명(61.3%), NSAID 복용자가 6명(19.4%), H. pylori 양성환자가 7명(22.6%) 있었다. 수술 전 내시경적 확장술은 2명에서 시도되었으며, 주병변의 위치는 위, 십이지장이 각각 9명, 20명, 양쪽이 2명이었다. 수술 후 합병증은 13명 (41.9%)에서, 궤양의 재발은 2명(6.5%)에서 있었고, 재수술이 4명(12.9%)에서 필요하였다. 평균 Visick score는 1.8 (1~4)이었다. 우회수술군과 절제수술군의 비교에서 두 군의 임상병리학적 차이는 없었으며, 두 군에서 각각 1명이 재발되었고 합병증은 각각 5명(83.3%), 8명(32%)으로 우회수술군에서 많았으나 통계적 유의성은 없었다(P=0.175). 평균 Visick score는 각각 3.0점, 1.6점으로 절제수술군에서 좋은 결과를 보였다(P=0.001). 결론: 만성 소화성 궤양으로 배출구 폐색을 동반한 환자의 치료에 있어서 내시경적 확장술 등의 비수술적 치료가 비교적 좋은 결과를 보고하고 있지만 여전히 수술은 중요한 치료 방법이다. 궤양 폐색의 수술적 치료시 악성 궤양과의 감별이 용이하지 않고 수술 후 환자의 만족도를 고려한다면 우회수술보다는 절제수술이 바람직한 술식으로 생각된다.

  • Backgrounds/Aims: Gallstone disease is a recognized complication of bariatric surgery. Subsequent management of choledocholithiasis may be challenging due to altered anatomy which may include Roux-en-Y gastric bypass (RYGB). We conducted a retrospective service evaluation study to assess the safety and efficacy of endoscopic ultrasound-directed transgastric endoscopic retrograde cholangiopancreatography (EDGE) in patients with RYGB anatomy. Methods: All the patients who underwent EDGE for endoscopic retrograde cholangiopancreatography after RYGB at two tertiary care centers in the United Kingdom between January 2020 and October 2021 were included in the study. Clinical and demographic details were recorded for all patients. The primary outcome measures were technical and clinical success. Adverse events were recorded. Hot Axios lumen apposing metal stents measuring 20 mm in diameter and 10 mm in length were used in all the patients for creation of a gastro-gastric or gastro-jejunal fistula. Results: A total of 14 patients underwent EDGE during the study period. The majority of the patients were female (85.7%) and the mean age of patients was 65.8 ± 9.8 years. Technical success was achieved in all but one patient at the first attempt (92.8%) and clinical success was achieved in 100% of the patients. Complications arose in 3 patients with 1 patient experiencing persistent fistula and weight gain. Conclusions: In patients with RYGB anatomy, EDGE facilitated biliary access has a high rate of clinical success with an acceptable safety profile. Adverse events are uncommon and can be managed endoscopically.

  • 목적: 진행성 위암 중 수술 소견에서 복강 내 원격전이가 존재하거나 주위 장기에 침윤이 심하여 절제가 불가능한 경우에 위 배출구 폐색을 동반하지 않더라도 예방적 위공장 우회술을 시행하는 경우가 있어, 단순 개복술 시행과 비교하여 그 의의를 알고자 하였다. 대상 및 방법: 1984년부터 2007년까지 고려대학교 의료원에서 수술을 시행 받은 진행성 위암 환자 중 위 배출구 폐색이 없고 절제 불가능한 4기 위암 환자 167예를 대상으로, 후향적 방법을 이용하여 임상병리학적 특성 및 치료성적, 그리고 예후 인자 분석을 시행하였다. 결과: 위 공장 우회술을 시행과 단순 개복술 시행을 비교한 결과, 나이, 성별, 간 전이 여부, 술 후 재원일, 재입원 횟수에서는 유의한 차이를 없었지만, 병소의 위치(P$\leq$0.014), 복막 파종(P=0.001)에서는 유의한 차이를 보였다. 예후 인자 분석에서는 위 공장 우회술을 시행한 군의 생존기간이 1~35.7개월(6.3개월), 시행하지 않은 군이 1~33.4개월(median 4.3개월)로 유의한 차이가 있었으며(P=0.031), 복막전이가 있는 경우 1~31.0개월(median 3.4개월), 없는 경우 1~33.3개월(median 5.8개월)로 유의한 차이를 보였다(P<0.001). 다변량 분석을 통한 독립적 예후 인자로는 복막 전이 여부만이 의미가 있었다(P=0.002). 결론: 절제 불가능한 4기 위암 환자에서 폐색 증상이 없는 경우, 예방적 위 공장 우회술은 생존기간의 연장에서 큰 의의를 가지지 못하는 것으로 생각한다.

  • 악성 위배출구 폐색을 동반한 위암의 경우 주위 장기 침습이 종종 관찰되며 수술적 절제가 불가능한 경우가 많다. 이런 경우 일차적으로 외과적 우회술을 시행하여 폐색을 해결하고 경구 섭취가 가능하게 하는 고식적인 치료를 시행해왔다. 최근 여러 스텐트의 개발은 절제 불가능한 위배출구 환자의 치료에 효과적으로 사용되고 있으나 이런 환자들의 고식적인 치료 방법의 결정에는 아직 논란의 여지가 있다. 스텐트 시술은 비교적 간단하고, 빠른 음식물 섭취 회복, 짧은 재원 기간, 합병증이 적다는 장점이 있다. 반면 외과적 우회술과 비교해 음식물과 암종의 과도한 성장에 의한 재폐색이 잦아 재수술이 필요한 경우가 많아 기대 생존 기간이 짧은 경우 유용하며, 수술적 우회술은 장기적인 결과가 좋아 기대 수명이 긴 경우 유용하다. 또한 아직까지 술 전 정확한 절제 가능성을 판단할 수 없기 때문에 수술적 치료는 근치적 절제의 기회가 주어지는 장점이 있다. 그러나 이전 보고들의 대상이 대부분 췌십이지장 암이며, 또한 전향적 무작위 대조군 연구가 거의 없어 위배출구 폐색을 동반한 위암 환자에서 치료방법의 결정을 위해서는 향후 위암 환자만을 대상으로 한 개복, 복강경, 그리고 스텐트 시술을 비교한 대규모 무작위 대조군연구가 필요하겠다.

  • Background/Aims: We compared outcomes between use of 15 vs. 20 mm lumen-apposing metal stents (LAMSs) in endoscopic ultrasound-guided gastroenterostomy (EUS-GE) for gastric outlet obstruction. Methods: Databases were queried for studies that used LAMS for EUS-GE to relieve gastric outlet obstruction, and a proportional meta-analysis was performed. Results: Thirteen studies were included. The 15 mm and 20 mm LAMS had pooled technical success rates of 93.2% (95% confidence interval [CI], 90.5%-95.2%) and 92.1% (95% CI, 68.4%-98.4%), clinical success rates of 88.6% (95% CI, 85.4%-91.1%) and 89.6% (95% CI, 79.0%-95.1%), adverse event rates of 11.4% (95% CI, 8.1%-15.9%) and 14.7% (95% CI, 4.4%-39.1%), and reintervention rates of 10.3% (95% CI, 6.7%-15.4%) and 3.5% (95% CI, 1.6%-7.6%), respectively. Subgroup analysis revealed no significant differences in technical success, clinical success, or adverse event rates. An increased need for reintervention was noted in the 15 mm stent group (pooled odds ratio, 3.59; 95% CI, 1.40-9.18; p=0.008). Conclusions: No differences were observed in the technical, clinical, or adverse event rates between 15 and 20 mm LAMS use in EUS-GE. An increased need for reintervention is possible when using a 15 mm stent compared to when using a 20 mm stent.

  • Currently, metabolic surgery (Laparoscopic Roux-en-Y gastric bypass, LRYGB) has an important role and should be recommended as an intervention in the management of obese patients with type 2 diabetes mellitus (T2DM). A successful outcome of surgery requires medical nutrition therapy. Therefore, we performed a retrospective study on 25 patients with T2DM who underwent LRYGB at Yeouido St. Mary's Hospital from October 2008 to May 2010. The patients were followed up for an average of 6 months after surgery (range: 2~19 months). Diabetes was resolved in 80% of the patients. Percentage of excess weight loss was (%EWL) was 56.2%. After surgery, fasting blood sugar (FBS) and HbA1c were significantly reduced (123 mg/dl, A1c 6.7%, P<0.001) and triglyceride was also significantly reduced to 107.6 mg/dl (P<0.05). As diets of the patients progressed from liquid to soft to regular diet, energy, carbohydrates, and fat intakes increased significantly (P<0.001). But protein intake did not change significantly. Nutrient intake of the patients after the surgery was significantly lower than the recommended diet for the non-surgery group. Patients experienced side-effects related to the diets after surgery, including hair-loss (76%), smelly gas (52%), vomiting (48%), etc. A significantly positive correlation was observed between vomiting and FBS (P<0.001). There was a significant relationship between side effects and the amount of nutrient intakes. Therefore, guide patients to a diet progression with treatment to minimize side effects, especially vomiting. And monitor their dietary life to be healthy and not to regain weight until remission of T2DM.

  • Purpose: This study primarily aimed to investigate the short- and long-term remission rates of type 2 diabetes (T2D) in patients who underwent surgical treatment for gastric cancer, especially patients who were non-obese, and secondarily to determine the potential factors associated with remission. Materials and Methods: We retrospectively reviewed the clinical records of patients with T2D who underwent radical gastrectomy for gastric cancer, from January 2008 to December 2012. Results: T2D improved in 39 out of 70 (55.7%) patients at the postoperative 2-year follow-up and 21 of 42 (50.0%) at the 5-year follow-up. In the 2-year data analysis, preoperative body mass index (BMI) (P=0.043), glycated hemoglobin (A1C) level (P=0.039), number of anti-diabetic medications at baseline (P=0.040), reconstruction method (statistical difference was noted between Roux-en-Y reconstruction and Billroth I; P=0.035) were significantly related to the improvement in glycemic control. Unlike the results at 2 years, the 5-year data analysis revealed that only preoperative BMI (P=0.043) and A1C level (P=0.039) were statistically significant for the improvement in glycemic control; however, the reconstruction method was not. Conclusions: All types of gastric cancer surgery can be effective in short- and long-term T2D control in non-obese patients. In addition, unless long-limb bypass is considered in gastric cancer surgery, the long-term glycemic control is not expected to be different between the reconstruction methods.

  • Long term patency of arterial graft has been better than venous graft and redo coronary artery bypass grafting has been increasing, therefore, there has been an increasing need for alternative arterial grafts except internal thoracic artery(ITA). Material and Method: Right gastroepiploic arteries(RGEA) were harvested from 100 patients who had received gastrectomy for gastric cancer or ulcer. ITAs were obtained from 10 patients undergoing coronary artery bypass grafting. The length of RGEA was measured from the pyloric ring. Items of the morphometric and histologic study at the pyloric ring and sites of the 10cm and 20cm RGEA from the pyloric ring were luminal diameter, intimal thickness, medial thickness, wall thickness, degree of intimal hyperplasia, intimal thickness, medial thickness, wall thickness, degree of intimal hyperplasia, intimal thickness index, medial thickness index, and the number of discontinuities of the internal elastic lamina. Similar items were applied to the proximal site of ITAs. Result: The length of RGEA was 23${\pm}$2.7cm(range 17∼31cm). Comparing the 20cm RGEA with ITA, intimal thickness, medial thickness, wall thickness, and degree of intimal hyperplasia did not show any difference(p>0.05). However, 20cm RGEA was greater than ITA at the luminal diameter, intimal thickness index, and the number thickness and wall thickness in each site of the RGEA(pyloric ring, 10cm, 20cm) decreased from the pyloric ring to the distal sites(p<0.05). The degree of intimal hyperplasia and the number of discontinuities of the internal elastic lamina did not show any difference between the pyloric ring and 10cm, however, those of 20cm were smaller than these sites(p<0.05). RGEA had more number of discontinuities of the internal elastic lamina and rich smooth muscle cells in the media than ITA. Conclusion: The length and diameter of RGEA is good enough to reach most of the coronary arteries. Moreover, long term patency of RGEA may be improved, if anastomosed in the distal site.
