Spontaneous bacterial peritonitis is defined as an ascitic fluid infection without an evident intra-abdominal surgically treatable source. The diagnosis is established by a positive ascitic fluid bacterial culture and an ascitic fluid absolute polymorphonuclear leukocyte(PMN)count≥250 cells/μL. Here we report the case of 81-year-old female patient who was diagnosed with spontaneous bacterial peritonitis after gastrectomy for gastric cancer. The laparoscopic distal gastrectomy and D1+ lymph node dissection were performed for Stage Ⅰ gastric cancer, and the postoperative course was uneventful. The patient presented with abdominal pain and was hospitalized again on the third day from the discharge. Computed tomography showed an accumulation of ascites, and the ascitic fluid polymorphonuclear leukocyte count was 9,973 cells/μL. The patient was diagnosed with spontaneous bacterial peritonitis, and antibacterial agent was performed. Abdominal pain and accumulation of ascites had been improved, and the ascitic fluid polymorphonuclear leukocyte count had decreased clearly. The patient discharged on the 57th day from the operation. Spontaneous bacterial peritonitis after gastrectomy for gastric cancer was rare. We report this rare case, along with a discussion of the literature.

The case was a 61-year-old woman. She was diagnosed with autosomal dominant polycystic kidney disease(ADPKD)at the age of 38 and started hemodialysis at the age of 42. She was diagnosed with rectal cancer(RS)at the age of 61. Laparoscopic high anterior resection and D3 lymphadenectomy were carried out. Although the intra-abdominal space was limited by the huge renal cysts, laparoscopic surgery can be safely performed by arranging the port closer to the midline, taking the patient's position sufficiently, and using some useful tips. Laparoscopic surgery for the patient with ADPKD was considered a useful approach.

Portal vein thrombosis after laparoscopic colorectal cancer surgery is rare and sometimes lethal. We report a case of asymptomatic portal vein thrombosis found during postoperative adjuvant chemotherapy(CAPOX)after laparoscopic surgery for rectal cancer. A male patient in his 60s underwent postoperative adjuvant chemotherapy( CAPOX). The elevation of liver enzyme before the chemotherapy was moderate enough to start. The liver enzyme was increased mildly during the chemotherapy. Computed tomography 27 weeks after the operation revealed the thrombus from the main portal vein to the right branch and posterior branch, and atrophy of the lateral segment with narrowed left branch. Blood flow was confirmed to be maintained by ultrasonic Doppler. We decided to discontinue the chemotherapy and started anticoagulant therapy with Warfarin. Thrombosis was disappeared 2 weeks later, and liver function went back to normal range after 8 weeks. Liver dysfunction during chemotherapy should be noted not only for drug-induced liver damage, but also for the possibility of postoperative asymptomatic portal vein thrombosis.

A 82-year-old man presented with diarrhea and fatigue. He had no past medical or surgical history except chronic renal failure. Locally advanced rectal cancer with invasion to left ureter was detected in computed tomography. Colonoscopy revealed a circular lesion 12 cm from the anal verge. Biopsy showed moderately differentiated adenocarcinoma. There was no sign of distal metastasis and we decided to conduct radical surgery. Robot-assisted laparoscopic lower anterior resection with partial resection of left ureter, and diverting ileostomy were carried out. Besides, urinary tract reconstruction of ureterocystoneostomy using Lich-Gregoir technique was conducted by urologists also with robot assistance. The pathological stage of the disease was pT4b(left ureter)N1bM0, pStage Ⅲc. The resection margin was secured and radical surgery was achieved. The patient was discharged on postoperative day 22nd without postoperative complication. He is alive without recurrence at 6 months after the operation.

A man in his 50s was admitted to our hospital due to hematemesis.Esophagogastroduodenoscopy revealed an 8 cm type 2 gastric tumor.The tumor was histologically diagnosed as a neuroendocrine carcinoma.CT showed that the tumor had directly infiltrated the liver but there was no distant metastasis.We performed open distal gastrectomy, D2 lymph node dissection, partial hepatectomy, and cholecystectomy.Four months after the surgery, metastases of the right adrenal gland and dorsal part of the inferior vena cava were found.Although a significant tumor reduction was obtained by 12 courses of chemotherapy with CDDP plus CPT-11, this effective treatment was discontinued for the patient's convenience.Fifteen months after the surgery, metastasis of the right adrenal gland and dorsal part of inferior vena cava demonstrated re-growth without any further metastasis.After 4 courses of the same regimen, a partial response was obtained for the recurrences.As a salvage surgery, we performed open right adrenal gland and the lymph nodes of dorsal of IVC resection.The patient is alive without recurrence 1 year after the salvage surgery.

Background: The choice of appropriate treatment in children with aortic valvular lesions remains controversial. The purpose of this study is to assess early and late outcomes of aortic valve replacement with annular enlargement in children., Methods: A retrospective study was conducted in 16 consecutive patients aged 0.26 to 15.9 years operated on between 1993 and 2008. Thirteen children underwent aortic valve replacement with Konno procedure (mechanical valve: 12, homograft: 1), 2 children underwent Ross procedure, and the last child underwent Nicks procedure with mechanical valve replacement. All patients undergoing mechanical valve replacement were given warfarin with a monthly international normalized ratio (INR) control., Results: Overall early mortality was 12.5% (2 cases). Emergency operation was performed in these cases because of infectious endocarditis and acute cardiac failure. However, cardiopulmonary bypass (CPB) weaning could not be obtained. There was 1 late death 5 months after mechanical valve replacement. The patient developed methicillin-resistant Staphylococcus aureus (MRSA) sepsis after cleft palate repair. Reoperation was needed in 1 case., Conclusion: We conclude that mechanical valve replacement with aortic annular enlargement is an acceptable treatment in children. It is associated with acceptable mortality and low incidence of late events, and provides long-term survival.

Background: Interrupted aortic arch (IAA) is associated with a multitude of lesions ranging from isolated ventricular septal defect to hypoplastic left ventricle or severe subaortic stenosis (SAS). Left ventricular outflow obstruction such as SAS continues to be an important factor for deciding the surgical procedure between univentricular and biventricular repairs., Methods: A retrospective study was conducted in 8 consecutive infants aged 14 to 117 days and operated on between 2004 and 2009. Seven patients had undergone bilateral pulmonary artery banding for pulmonary high flow regulation. All patients underwent Norwood-type operation (4 with systemic to pulmonary artery shunt, 3 with right ventricle to pulmonary artery shunt, and 1 with bidirectional Glenn shunt)., Results: One patient died 2 months after surgery due to respiratory failure. The others were discharged in a good condition. One patient underwent Rastelli-type operation and biventricular circulation was achieved. The other 6 patients were all Fontan candidates., Conclusion: Satisfactory initial palliation can be achieved by Norwood-type operation for IAA with severe SAS or hypoplastic left ventricular-aortic complex.

Operative correction of tetralogy of Fallot has been performed for more than 50 years and well established. To date, the literature on reoperation has focused and indications and the long-term outcome have not been well defined. We herein report a case of pulmonary valve replacement due to ectopic ossification on expanded polytetrafluoroethylene (ePTFE) cusp in a female child who had undergone right ventricular outflow tract reconstruction for tetralogy of Fallot with pulmonary atresia. Because of severe right ventricular dilatation with end diastolic volume of 186 ml/m2 on cardiac catheterization, redo operation was planned for functional recovery of the right ventricle. Previous transannlar patch was removed and pulmonary valve replacement was performed using CEP 23 mm. A hard calcification was observed around the cusp of transannular patch. Pathological findings revealed ectopic ossification with osteoblast colonization around the ePTFE cusp. This is the 1st report of ectopic ossification on ePTFE.

We report a female infant with acute coronary syndrome after Aubert-Imai modification for transposition of the great arteries. Two months postoperatively, she visited the emergency room because of perspiration and tachypnea. She was diagnosed with acute coronary syndrome by blood chemistry examination. Cardiac catheterization revealed Aubert route stenosis, and emergency operation was performed. The lumen around the aortopulmonary window was almost totally occluded by fibrous tissue extending from the equine pericardial patch. This fibrous tissue was completely resected and the aortopulmonary window was deepened to enlarge the coronary ostium. We recommend a close follow-up including angiography after these procedures.
