RESUMO
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract; most of them have gain-of-function mutations of the KIT gene. There have been rare cases of families with multiple GISTs, that had autosomal dominant germline KIT mutations. Here, we present a case of multiple GISTs caused by a novel germline KIT mutation. Intraoperatively, the main tumor was present in the body of the stomach, and multiple small nodules were detected mainly in the upper and middle part of the gastric wall; several nodules were also present in the small bowel wall. The main tumor and surrounding nodules were resected. DNA sequencing of the tumor tissue, adjacent normal mucosal tissue, and peripheral blood leukocytes revealed that the patient had germline Asp820Gly mutation in exon 17 of the KIT gene. This is the first case with germline Asp820Gly mutation in exon 17 of the KIT gene.

BACKGROUND: Delta-shaped anastomosis is a common method of intracorporeal gastroduodenostomy in totally laparoscopic distal gastrectomy. One common postoperative complication of this procedure is anastomotic stenosis, and endoscopic balloon dilatation is a major remedy for such complications. Other treatment strategies are necessary to manage unsuccessful endoscopic balloon dilatation. CASE PRESENTATION: We present a case where systemic steroid treatment was applied in sustained anastomotic stenosis after endoscopic balloon dilatation. We performed delta-shaped anastomosis in laparoscopic distal gastrectomy to treat early-stage gastric cancer in a patient. The patient experienced abdominal pain post-surgery; subsequent investigation revealed edematous anastomotic stenosis. The stenosis sustained even after endoscopic balloon dilatation and local steroid injection. Consequently, we applied systemic steroid treatment. CONCLUSION: Systemic steroid treatment improved the stenosis and no recurrence was observed. These results suggest that systemic steroid application could be useful to treat anastomotic stenosis.

A 78-year-old man who developed metastatic liver and lung cancer after undergoing surgery for rectal and sigmoid colon cancer was treated with TAS-102 as fourth-line chemotherapy. He developed high fever and dyspnea and was referred to the emergency room 16 days after receiving the first course of TAS-102. Chest X-ray and computed tomography examinations showed bacterial pneumonia. He was treated with tazobactam/piperacillin, but developed severe dyspnea 4 days later. A diffuse ground-glass appearance was observed in both the lungs on chest X-ray examination, and drug-induced interstitial pneumonitis was suspected. Oxygenation and respiratory support were immediately administered, and steroid pulse therapy with methylprednisolone at 1,000mg/day was initiated. His symptoms and radiographic findings dramatically improved. The TAS102-J003 trial, a double-blind phase 2 trial, showed that interstitial pneumonitis occurs at a rate of only 0.9%, but can lead to severe complications, as observed in the present case. The possibility of interstitial pneumonitis should always be considered when a patient develops a fever and respiratory disorder during treatment containing TAS-102.

The aim of this study was to evaluate the utility of immediate repair of a contralateral occult hernia at the same time as incipient hernia repair. A total of 693 patients were diagnosed preoperatively with a unilateral groin hernia from January 2006 to December 2017. The open technique was used for 541 patients, and the laparo-endoscopic technique was used for 152 patients. The incidences of occult contralateral hernia confirmed during surgery under laparo-endoscopic techniques and those of contralateral metachronous hernia after a unilateral groin hernia repair with open technique were compared. Fifty-one (9.4%) of 541 patients underwent a contralateral metachronous hernia repair after unilateral groin hernia repair. Twenty-three (15.1%) of 152 patients had occult contralateral hernias using laparo-endoscopic techniques. There was a significant difference in the incidence of contralateral metachronous hernia and that of occult contralateral hernia (P = 0.02). It is concluded that finding and repairing an occult contralateral hernia at the time of laparo-endoscopic technique has the advantage of avoiding a second operation. However, it has been considered overtreatment to repair all patients with an occult contralateral hernia.

We herein report 1 case in which hormone therapy and neoadjuvant chemotherapy by local intraarterial infusion were conducted for locally advanced breast cancer, and were revealed to be useful in terms of local control. Administration of doxifluridine (5'-DFUR: Furtulon) (1,200 mg/day, 5 day continuous dosing followed by 2 day washout) and medroxyprogesterone acetate (MPA: Hysron H) (1,200 mg/day) was followed by chemotherapy consisting of intraarterial infusion of 100 mg of docetaxel (TXT: Taxotere), once monthly, via the left internal thoracic artery and left lateral thoracic artery. As a result, marked shrinkage of tumors was confirmed. Under these circumstances, left standard radical mastectomy plus skin grafting were performed. While under treatment, no serious adverse events were observed, and the patient made satisfactory progress after surgical procedure. She thus left hospital in a positive frame of mind.

BACKGROUND: The VIO soft-coagulation system (SCS) is a new device for tissue coagulation. The current study evaluated the efficacy of the SCS when used for liver resection. METHODS: The 252 patients were divided into 2 groups; in 155 patients (conventional group), liver transection was performed using an ultrasonic dissector and saline-coupled bipolar electrocautery for hemostasis. In 97 patients (SCS group), the SCS was used instead of bipolar electrocautery. RESULTS: The median blood loss and surgical time were less in the SCS group than in the conventional group (350 vs 640 mL, P = .0028; 280 vs 398 min, P < .0001). No significant differences were found in postoperative complications between the SCS group (32.0%) and the conventional group (40.6%). The risk factors for bleeding were nonuse of the SCS (P = .0039), macroscopic vascular invasion of the hepatic tumors (P = .0088), and collagen type IV value in the sera >200 (P = .0250) on multivariate analysis. In a subgroup analysis, in the collagen type IV value >200 subgroup, the tumor diameter >5 cm subgroup, and the inflow nonocclusion subgroup, use of the SCS decreased surgical bleeding (P = .0120, P = .0126, and P = .0032, respectively) and surgical time (P = .0001, P < .0001, and P = .0036, respectively) compared with the conventional group. Furthermore, even in the major hepatectomy group, the SCS use decreased surgical time (P < .0001). CONCLUSION: The SCS is an effective and safe device for decreasing surgical time and surgical bleeding without increasing the rate of bile leakage and causing other complications.

Late-onset hepatic failure, the least of the fulminant hepatic failures, has not occurred in patients with hepatitis A virus-related acute liver failure. We report a rare case of hepatitis A virus-related late-onset hepatic failure treated successfully by an emergent liver transplant. A 58-year-old Japanese woman who presented with fever and general malaise was diagnosed as having jaundice and liver dysfunction by a positive serum test for anti-hepatitis A virus IgM, which ultimately led to a diagnosis of acute hepatitis A virus associated hepatitis. Despite intensive treatment, her general condition was poor, and she developed a hepatic coma 79 days from the onset of the disease. Under a diagnosis of hepatitis A virus-related late onset hepatic failure, she was given a living-donor liver transplant 82 days from the start of the disease. The resected native liver revealed submassive necrosis with marked cholestasis, compatible with late-onset hepatic failure. Today, 5 years after the transplant, she is alive and well with no signs of recurrent hepatitis A virus-hepatitis. This case should alert the physician to the clinical management of a patient with hepatitis A virus-related acute liver failure.

Adult-to-adult living donor liver transplantation (ALDLT) has been accepted as an important option for end-stage liver disease, but information regarding the risk factors remains fragmentary. We aimed to establish a predictive model for 90-day survival. In the first step, a total of 286 cases who had received primary ALDLT using a right lobe graft between 1998 and 2004 were randomly divided into 2 cohorts at a ratio of 2:1 (191 vs. 95 recipients). The larger cohort of patients was used to develop a model. The outcome was defined as 90-day survival, and a total of 39 preoperative and operative variables, including the period of surgery (1998-2001 vs. 2002-2004), were included using Cox's proportional hazard regression model. Two mismatches of human leukocyte antigen (HLA) type DR (hazard ratio [HR] = 4.45; confidence interval [CI] = 1.96-10.1), log(e)[blood loss volume] (HR = 2.43; CI = 1.64-3.60), period of surgery (1998-2001 vs. 2002-2004) (HR = 2.41; CI = 1.04-5.57), and log(e)[serum C-reactive protein or CRP] (HR = 1.64; CI = 1.13-2.38) were found to be independent risk factors. In the second step, we tried to establish a realistic survival model. In this step, we created 2 models, 1 that used all 4 variables (model 1) and 1 (model 2) in which blood loss volume was replaced with the past history of upper abdominal surgery and Model for End-Stage Liver Disease (MELD) score (> or =25), both of which showed associations with blood loss volume. These models were applied to the smaller cohort of 95 patients. Receiver operating characteristic analyses demonstrated that both models showed similar significant c-statistics (0.63 and 0.62, respectively). In conclusion, model 2 can provide a rough estimation of the 90-day survival after ALDLT.
