[Purpose] This study aimed to examine the validity and reproducibility of a new quantitative method for measuring spinal kyphosis using computed tomography (CT), and to investigate its relationship with reflux esophagitis. [Method] Using a new method to measure the index of kyphosis in CT images (IKCT), 10 examiners evaluated 10 cases of spinal kyphosis. One examiner measured 47 cases twice and 20 cases were examined to assess the validity with the kyphosis index. A case-control study was conducted on 303 cases of reflux esophagitis, of which 241 were mild and 62 severe. [Results] Regarding IKCT reproducibility, the inter-rater intraclass correlation coefficient was 0.977. The intra-rater intraclass correlation coefficient was 0.974. The correlation index with the kyphosis index was 0.731. A greater IKCT value, not contracting serious atrophic gastritis, and severe hiatal hernia were identified as risk factors for severe reflux esophagitis. [Conclusion] IKCT is a simple and useful method for measuring kyphosis. The prevention of kyphosis can help suppress severe reflux esophagitis.
The short- and long-term outcomes of 34 patients with refractory malignant ascites who underwent peritoneovenous shunt (PVS) therapy were retrospectively reviewed. The primary disease was gastrointestinal cancer in 31 patients and gynecologic cancer in 3 patients. Regarding performance status, 21 patients had Eastern Cooperative Oncology Group Performance Status (PS) 2 and 13 patients were PS 3;thus, many were in a poor general condition. After treatment, abdominal distention disappeared in 79.4% of patients, and appetite improved in 60.9%. The median postoperative survival time was 38 days (range, 1-294 days), and 18 patients (52.9%) were discharged. Disseminated intravascular coagulation with clinical symptoms was observed in 3 patients (8.8%), and heart failure was observed in 7 patients (20.6%). PVS therapy was useful in improving the subjective symptoms of patients with refractory malignant ascites and in enabling them to receive care at home. However, serious postoperative complications are a concern, and appropriate preoperative evaluation is necessary.
A 73-year-old man underwent pancreatoduodenectomy 5 years previously, and portal vein stenosis was observed immediately after surgery. A collateral vein with varices around the hepaticojejunostomy gradually developed. The patient experienced repeated episodes of melena that required transfusion. Enteroscopy confirmed varices around the hepaticojejunostomy, caused by portal vein stenosis, which was the source of intestinal bleeding. Varices were treated by placing an expandable metallic stent in the stenotic portal vein through a percutaneous transhepatic route. Although the portal vein stenosis was severe, the guidewire was successfully maneuvered into the superior mesenteric vein and stent placement was successful. Subsequently, the collateral vein disappeared and no further melena was observed.
A 56-year-old woman with epigastric pain was admitted to our hospital. Blood tests and abdominal computed tomography (CT) suggested acute pancreatitis. Abdominal CT revealed a pancreas divisum and stone in the minor papilla. Stone impaction was the most likely cause of the acute pancreatitis. The patient's abdominal pain promptly improved after admission. The patient was treated conservatively, and the pancreatitis resolved. Abdominal CT on the 10th day confirmed spontaneous evacuation of the pancreatic stone. This is a rare case of acute pancreatitis in a patient with pancreas divisum triggered by an impacted stone in the minor papilla, which improved after spontaneous evacuation of the pancreatic stone.
