Purpose: No consensus exists on whether to preserve or ligate an aberrant left hepatic artery (ALHA), which is the most commonly encountered hepatic arterial variation during gastric surgery. Therefore, we aimed to evaluate the clinical effects of ALHA ligation by analyzing the perioperative outcomes. Materials and Methods: We retrospectively reviewed the data of 5,310 patients who underwent subtotal/total gastrectomy for gastric cancer. Patients in whom the ALHA was ligated (n=486) were categorized into 2 groups according to peak aspartate aminotransferase (AST) or alanine aminotransferase (ALT) levels: moderate-to-severe (MS) elevation (≥5 times the upper limit of normal [ULN]; MS group, n=42) and no-to-mild (NM) elevation (<5 times the ULN; NM group, n=444). The groups were matched 1:3 using propensity score-matching analysis to minimize confounding factors that can affect the perioperative outcomes. Results: The mean operation time (P=0.646) and blood loss amount (P=0.937) were similar between the 2 groups. The length of hospital stay was longer in the MS group (13.0 vs. 7.8 days, P=0.022). No postoperative mortality occurred. The incidence of grade ≥ IIIa postoperative complications (19.0% vs. 5.1%, P=0.001), especially pulmonary complications (11.9% vs. 2.5%, P=0.003), was significantly higher in the MS group. This group also showed a higher Comprehensive Complication Index (29.0 vs. 13.9, P<0.001). Conclusions: Among patients with a ligated ALHA, those with peak AST/ALT ≥5 times the ULN showed worse perioperative outcomes in terms of hospital stay and severity of complications. More precise perioperative decision-making tools are needed to better determine whether to preserve or ligate an ALHA.

Purpose: During laparoscopic gastrectomy, an aberrant left hepatic artery (ALHA) arising from the left gastric artery (LGA) is occasionally encountered. The aim of this study was to define when an ALHA should be preserved during laparoscopic gastrectomy. Materials and Methods: From August 2009 to December 2014, 1,340 patients with early gastric cancer underwent laparoscopic distal gastrectomy. One hundred fifty patients presented with an ALHA; of the ALHA was ligated in 116 patients and preserved in 34 patients. Patient characteristics, postoperative outcomes and perioperative liver function tests were reviewed retrospectively. Correlations between the diameter of the LGA measured on preoperative abdominal computed tomography and postoperative liver enzyme levels were analyzed. Results: Pearson's correlation analysis showed a positive correlation between the diameter of the LGA and serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels on postoperative day 1 in the ALHA-ligated group (P=0.039, P=0.026, respectively). Linear regression analysis estimated the diameter of the LGA to be 5.1 mm and 4.9 mm when AST and ALT levels were twice the normal limit on postoperative day 1. Conclusions: We suggest preserving the ALHA arising from a large LGA, having diameter greater than 5 mm, during laparoscopic gastrectomy to prevent immediate postoperative hepatic dysfunction.

A recent successful prospective randomized control study comparing open distal pancreatectomy with laparoscopic distal pancreatectomy (LDP) has shown that LDP is a safe and effective surgical modality in treating left-sided pancreatic pathological conditions requiring surgical extirpation. With the accumulating surgical experiences and improved surgical techniques, we recently reported several cases of successful LDP in advanced pancreatic cancer following neoadjuvant chemotherapy. Herein, we report a case of LDP with celiac axis resection (LDP-CAR) in locally advanced pancreatic cancer (LAPC) following neoadjuvant chemotherapy. A 58-yearold female with LAPC was referred to our institution. Computed tomography (CT) findings revealed a 24-mm mass in the pancreatic body that showed celiac artery (CA), common hepatic artery abutment. There was no abutment with superior mesenteric artery, superior mesenteric vein, and portal vein. From these findings, Neoadjuvant chemotherapy (FORFIRINOX) was performed biweekly. After 8 cycles of chemotherapy, the tumor size was slightly decreased (24 mm to 16 mm), but still abutting to CA. After 14 cycles of chemotherapy, CT revealed the same tumor size (16 mm) still abutting to CA. LDP-CAR was performed. Intraoperative ultrasonography gastric perfusion and hepatic perfusion were confirmed using indocyanine green. The patient recovered without complications and was discharged from the hospital nine days after the surgery.

Alagille syndrome (AGS) is a rare autosomal dominant inherited disorder, with major clinical manifestations of bile duct paucity, cholestasis, cardiovascular anomaly, ophthalmic abnormalities, butterfly vertebrae, and dysmorphic facial appearance. It is caused by heterozygous mutations in JAG1 or NOTCH of the Notch signaling pathway presenting with variable phenotypic penetrance and involving multiple organ systems. The following case report describes a unique case of a 16-year-old female with AGS who presented with the primary complaint of renovascular hypertension. She had a medical history of ventricular septal defect and polycystic ovary syndrome. The patient had a dysmorphic facial appearance including frontal bossing, bulbous tip of the nose, a pointed chin with prognathism, and deeply set eyes with mild hypertelorism. Stenoocclusive changes of both renal arteries, celiac artery, lower part of the abdominal aorta, and left intracranial artery, along with absence of the left internal carotid artery were found on examination. Whole exome sequencing was performed and revealed a pathologic mutation of JAG1, leading to the diagnosis of AGS. Reverse phenotyping detected butterfly vertebrae and normal structure and function of the liver and gallbladder. While the representative symptom of AGS in most scenarios is a hepatic problem, in this case, the presenting clinical features were the vascular anomalies. Clinical manifestations of AGS are diverse, and this case demonstrates that renovascular hypertension might be in some cases a presenting symptom of AGS.

Alagille 증후군은 간내 담도 형성 부전으로 인한 만성 담즙 정체, 말초 폐동맥 협착, 골격 이상, 눈의 이상, 특징적인 얼굴 모양 등을 주요 증상으로 하는 상염색체 우성 유전 질환으로 말초 폐동맥 협착 이외에도 여러 말초 혈관 병변들이 동반된다. 관련된 유전자로 20번 염색체 위에 존재하는 JAG1이 발견되었고, 이 유전자의 결손으로 인한 Notch 신호전달체계의 결함이 혈관형성에 영향을 미친다고 생각되고 있다. Alagille 증후군에서 만성 뇌동맥 폐색질환인 moyamoya병이 발생한 예들이 보고된 바 있는데, Alagille 증후군의 혈관병증의 또 다른 한 발현으로 이해되어야 할 것이다. 저자들은 생후 2개월에 Alagille 증후군을 진단받고 추적 관찰 중에 갑자기 편측 마비가 발생하여 뇌혈관 조영술을 통해 moyamoya병을 진단받은 25개월 여아를 경험하였기에 이를 보고하는 바이다.

Eighty-four cases of mitral commissurotomy were done in this department between October 1958 and September 1970. Therc wcre 54 males and 30 females. Six cases were under the age of 20 years. Prcoperativc embolization occurred in 9. 5% of the cases. consisting of 8. 3% cerebral and 1.2% peripheral embolization. Intraoperative and postoperative cmbolization occurred in 4.7% of the cases, with 1. 2% cerebral and 3.5% peripheral embolism. Two out of three postopeative embolism cases expired, one of which was caused by septic cerebral embolism due to valve vegetation nnd the other by mesenteric embolism. Atrial fibrillation was 1loted ill 43% of the case. Seventy closed mitral commissurotomy was done by left appendegeal approach with finger fracture method or Bailey's guillotine valvotome. Fourteen open mitral commissurotomy cases were done either by right side approach or median sternotomy, three of which were reoperation cases after blind mitral commissurotomy. One out of 14 cases were operated on with open mitral commissurotomy and concomitant open aortic valve bicuspidalization, This case expired due to severe serum hepatitis ten days after operation. Thirty-two per cent of valve calcification was noted during operation and one of which had marked vegetation on the valve cusps too. Operative mortality was 1.4% in blind mitral commissurotomy and 14% in open mitral commissurotomy. Over-all mortality in the entire series was 3.5%. One case among the blind commissurotomy cases expired during operation due to left inferior pulmonary vein laceration and death was caused in two open mitral commissurotomy cases by coronary artery airembolism. Three hospital death occurred in blind operation group, one due to coronary embolism, and two by hepatic failures. Three hospital death among open heart surgery cases were caused by hepatic failure in two and cerebral embolism in one cases. ln most of the survivors improved functional capacity and exercise lolerance were noted.
