ABSTRACT
An 86-year-old woman visited our hospital at 20:00 with the chief complaint of right hip joint pain that had started at around 19:30. The abdomen was soft and slightly bloated, and there was tenderness in the right hip joint. Computed tomography (CT) revealed protrusion of the small intestine through the right obturator foramen, and right-sided impacted obturator hernia was diagnosed. Intestinal necrosis was unlikely because her symptoms had started only a short time earlier, so manual reduction was performed. The right hip joint pain was rapidly alleviated, and CT confirmed release of the incarcerated bowel. Elective laparoscopic repair was then performed. Hemorrhagic ascites in the abdominal cavity, but no obvious intestinal ischemia, was evident. Intestinal dilation was relieved, enabling us to perform surgical maneuvers in a good surgical field. The postoperative course was favorable, and there has been no recurrence as of 2 years 11 months after surgery. Obturator hernia is common in elderly women, who often have several comorbidities. Avoidance of emergency surgery by manual reduction is therefore significant, and laparoscopic surgery that enables assessment and treatment of the contralateral side is beneficial.
ABSTRACT
The patient was a 73-year-old man. He had sustained a spinal cord injury in a work-related accident at 40 years of age and was living with lower body paralysis. He had defecation disorder due to poor intestinal peristalsis of the sigmoid colon. Colostomy was indicated because the defecation disorder had worsened to the extent that hospital management was required. We selected a laparoscopic approach for two reasons. First, at the time of the accident, he had undergone thoracotomy and laparotomy to treat diaphragm injury and we expected that adhesions would need to be removed in the abdominal cavity. Second, patients with spinal cord injury are prone to poor bowel peristalsis, and minimally invasive surgery should be used to prevent postoperative paralytic ileus. The operation was performed with three ports. Adhesions of the transverse colon, omentum, and abdominal wall were peeled off, the transverse colon was mobilized, and a transverse colostomy was created in the upper right abdomen. The postoperative course was favorable, and he resumed eating on postoperative day 2. Laparoscopic colostomy for patients with spinal cord injury and defecation disorder can be a safe and effective technique for improving quality of life.
ABSTRACT
Patient 1 was a 73-year-old woman with chief complaints of abdominal pain and prolapse of bowel through the anus. About 10 cm of the intestine had prolapsed through the anus, and a mass was observed at the invasive front. Computed tomography (CT) revealed the classic target sign of an intussusceptum inside an intussuscipiens, where the sigmoid colon had intussuscepted into the rectum. Patient 2 was a 92-year-old woman who presented with a chief complaint of melena. About 5 cm of the intestine had prolapsed through the anus, and a mass was observed at the invasive front. CT showed the classic target sign in the rectum. Based on physical examination and CT findings, both cases were diagnosed as intussusception caused by progression of colorectal cancer. Manipulative reduction was attempted before surgery, but neither intussusception could be reduced and thus Hartmann’s operation was performed for both patients. Patient 1 had an uneventful postoperative course and was discharged on hospital day 36. Patient 2 developed prolonged paralytic ileus due to unsuccessful mobilization and was discharged on hospital day 80. Abdominoperineal resection is required for irreducible prolapse of intussusception through the anus due to colorectal cancer, and this invasive procedure can cause complications. Many patients with this condition are elderly adults with weak pelvic supporting tissue, and thus treatment suited to each individual patient must be selected.
ABSTRACT
A 69-year-old man, who had undergone coronary artery bypass grafting using the right gastroepiploic artery 2 years previously, was hospitalized with acute epigastralgia. Gastroscopy showed an early gastric cancer in the greater curvature of the corpus and ultrasonography of the abdomen revealed acute cholecystitis due to a stone impacted in the cystic duct. The subtotal gastrectomy and the cholecystectomy with preservation of the right gastroepiploic artery graft were performed. The surgical margin of the resected specimen was negative for cancer. The postoperative course was uneventful. After coronary artery bypass grafting using the right gastroepiploic artery, annual gastroscopy is recommended.
ABSTRACT
The early postoperative use of continuous hemodiafiltration (CHDF) was effective in the postoperative management of two patients with chronic renal failure (CRF) undergoing cardiovascular operation. The first case was a 74-year-old man with a ruptured abdominal aortic aneurysm who underwent emergency Y-shaped artificial graft replacement. The second case was a 55-year-old man with aortic valve stenosis and regurgitation who underwent aortic valve replacement with a mechanical cardiac valve. Both patients had had chronic renal failure for several years before the operation, and the second patient had been on intermittent hemodialysis. Although a large amount of blood transfusion was needed postoperatively in both cases, CHDF enabled us to maintain the electrolytes in the normal range and control the water balance. The influence on the hemodynamics was minimized by adjusting the filtration rate. In conclusion, CHDF is useful for the management of CRF in the early postoperative period following cardiovascular surgery.
ABSTRACT
From April 1987 to March 1990, we performed open heart surgery using extracorporeal circulation in 90 patients (average age, 51.8 years old) and vascular surgery (graft replacement of abdominal aortic aneurysm and surgery for ASO) in 29 patients (average age, 58.1 years old). Among there, 8 patients with open heart surgery (EEC group) and 9 patients with vascular surgery (vascular group) had suffered from renal insufficiency preoperatively. In the two groups, we compared operative mortality, complications and postoperative severity of renal failure. Preoperative renal insufficiency was defined as a serum creatinine level of more than 1.4mg/dl and postoperative renal failure was defined as 2.0mg/dl. There was no significant difference in operative mortality, in postoperative creatinine, Ccr, BUN and serum potassium and in effectiveness of hemodialysis in the two groups. In conclusion, it seems that we should not hesitate to perform cardiovascular surgery with extracorporeal circulation for patients with renal insufficiency or in hemodialized patients.
ABSTRACT
This is a case report of a 40-year-old man with leiomyosarcoma of the inferior vena cava. He had suffered from shortness of breath and edema on lower limbs over several months. Clinical examinations including UCG, CT and MRI revealed the mass in the right atrium. The stalk of mass was located near junction of the right atrium and inferior vena cava by cavography. He was operated upon using extracorporeal circulation. The tumor originated from inferior vena cava, measuring 8.5×5.5×4.8cm in size, 130g in weight, was successfully removed. Partial defect of anterior wall on the inferior vena cava was reconstructed using Gore-Tex patch. Histologically, the tumor was composed of the spindled cells with arranged bundles. Immunohistochemically, they were positive for Dessmin and Vimentin. Seven months after the surgery, he has been followed at OPD. In review of the Japanese literature to our knowledge, only 14 cases were reported including this case.
ABSTRACT
A case of a 51-year old male with pulmonary valve endocarditis accompanied by aortic regurgitation, and ruptured aneurysm of Valsalva sinus was reported. Repeated blood cultures grew <i>α-streptococcus</i> on a single occasion. After medical treatment, resection of pulmonary valve vegetation, resection and patch closure of aneurysm, and aortic valve replacement were performed successfully. Twenty one cases of pulmonary valve endocarditis reported in Japan, including our case, were collected and reviewed. Causative organism was <i>streptococcus</i> in 93% of cases. No case of intravenous drug abuse was found in this series. A variety of preexisting heart diseses were found in 20 cases out of 21 (95%). All these diseases were congenital ones, such as ven-tricular septal defect, patent ductus arteriosus, pulmonary stenosis and ruptured aneurysm of Valsalva sinus. This fact means that jet lesion of pulmonary valve is a major predisposing factor of pulmonary valve endocarditis. Surgical procedures were reported in 12 cases: resection of vegetation in 4 cases, resection of pulmonary valve in 2, and pulmonary valve replacement in 5. Appropriate surgical procedures should be chosen, depending upon the activity of infective endocarditis, severity of destruction of the valve, and pulmonary vascular resistance.
ABSTRACT
A case of xenograft valve dysfunction presenting with musical cooing murmur is reported. The patient was a 47-year-old woman and had received mitral valve replacement with porcine xenograft (Carpentier-Edwards 31-M) 10 years before Preoperative echocardiogram showed vibration of a leaflet outside the stent of the bioprosthetic valve. Cardiac catheterization revealed stenosis as well as regurgitation of the bioprosthetic valve. The resected xenograft valve showed a tear which produced regurgitation and musical cooing murmur in one of three pliable leaflets and it also showed pannus formation which caused stenosis.
