1/38. Perforated duodenal diverticulum: report of two cases.Duodenal diverticula may be complicated by diverticulitis, perforation, hemorrhage, pancreatitis, or biliary obstruction. Two cases of perforated duodenal diverticulum are reported. Both patients were elderly females. Computed tomography of the abdomen showed retroperitoneal air around the duodenum in the first case, and an enterolith in a duodenal diverticulum and a retroperitoneal abscess in the second case. laparotomy and diverticulectomy with two-layer closure of the duodenum was performed in the first case. The second patient was treated conservatively with antibiotics, percutaneous abscess drainage, and endoscopic lithotomy. Both recovered well. Computed tomography is useful in the diagnosis of a perforated duodenal diverticulum. Although surgical intervention is the standard treatment, conservative therapy is also an option. Duodenal enteroliths are rare but may cause perforation of a diverticulum or biliary obstruction. The duodenal blind loop created by a Billroth II gastrectomy provides a static environment for the formation of enteroliths in duodenal diverticula.- - - - - - - - - - ranking = 1keywords = gas (Clic here for more details about this article) |
2/38. Clinical and radiological findings in patients with gas forming renal abscess treated conservatively.PURPOSE: Emphysematous pyelonephritis in diabetics is considered a potentially lethal infection. mortality rates of patients treated conservatively approaches 80% in some series. These patients often present with signs of sepsis or septic shock. In contrast, gas forming renal abscess is rare, with patients presenting entirely differently from those with emphysematous pyelonephritis. To our knowledge this process has been previously described only in isolated case reports. We describe a series of 5 patients with this distinct process. MATERIALS AND methods: We reviewed the clinical and radiological features of 5 patients with gas forming renal abscesses. RESULTS: Each patient presented with diabetes mellitus with initial blood glucose ranging from 313 to 552 mg./dl., fever (average 101F), flank or abdominal pain and pyuria. No patient had evidence of septic shock at hospitalization. escherichia coli was the documented organism in each case. Mild renal insufficiency was noted in most patients based on serum creatinine. Radiological evaluation revealed gas filled pockets within the renal parenchyma, which were most effectively shown by computerized tomography (CT) of the abdomen. There was no radiological evidence of pus. Percutaneous drainage of an abscess in 1 case did not produce any purulent material or alter the clinical course. Each patient responded to correction of the underlying metabolic abnormalities with intravenous antibiotics (average 23 days) followed by prolonged oral antibiotic therapy (average 9 weeks). In contrast to the management of emphysematous pyelonephritis, surgical or percutaneous drainage was not necessary. Serial CT revealed complete resolution of gas in the parenchyma within 6 months in patients with long-term followup. Of note, gas was persistent on CT months after infection had clinically resolved. CONCLUSIONS: We describe a unique entity within the spectrum of pyelonephritis. The clinical appearance of gas forming abscesses within the renal parenchyma without liquefaction in diabetic patients was remarkably benign compared to the radiographic appearance of the disease process. Conservative management with intravenous and oral antibiotics was successful in each patient, avoiding the need for invasive intervention.- - - - - - - - - - ranking = 10keywords = gas (Clic here for more details about this article) |
3/38. abdominal abscess: late complication after gastroepiploic coronary artery bypass grafting.The gastroepiploic artery is widely used an arterial conduit during coronary artery revascularisation surgery. We report an unusual complication of a 56-year-old man who developed a late intra-abdominal abscess extending into the mediastinum adjacent to the right ventricle more than 2 years after surgery. This was managed with percutaneous drainage and the patient made a full recovery. The case illustrates the potential problems associated with harvesting of this artery and the need for careful haemostasis.- - - - - - - - - - ranking = 5keywords = gas (Clic here for more details about this article) |
4/38. Unilateral chronic tuboovarian abscess secondary to ruptured colonic diverticulum presenting as a brain abscess. A case report.BACKGROUND: Tuboovarian abscesses (TOAs) are a somewhat unusual finding in postmenopausal patients without risk factors. We present a rare case of unilateral TOA initially presenting as a brain abscess in a postmenopausal woman. CASE: A 61-year-old woman presented with a complaint of forgetfulness, nausea and vomiting, with lower abdominal pain and diarrhea. She was found to have a brain abscess, which was treated by craniotomy, with drainage of the abscess, and intravenous antibiotics. The patient was subsequently found to have a pelvic mass, which, on laparotomy, was a unilateral TOA. pathology demonstrated that the abscess contained vegetable matter consistent with origin in a ruptured diverticulum. CONCLUSION: diagnosis of a brain abscess should prompt a thorough investigation for a primary infectious source, including the gastrointestinal and genitourinary tracts.- - - - - - - - - - ranking = 1keywords = gas (Clic here for more details about this article) |
5/38. Retroperitoneal teratoma presenting as acute abdomen in an elderly person.A 56-year-old man presented with acute abdomen. Clinically, he was diagnosed as having perigastric abscess. On exploration, a retroperitoneal cystic teratoma was encountered. Postoperatively, he recovered uneventfully and has no residual disease two years later.- - - - - - - - - - ranking = 1keywords = gas (Clic here for more details about this article) |
6/38. Bilateral emphysematous pyelonephritis with perirenal abscess cured by conservative therapy.Emphysematous pyelonephritis is a rare life-threatening infection of the renal parenchyma. It usually affects unilateral kidney and occurs mostly in diabetic patients. It is characterized by the presence of gas within the renal parenchyma and requires prompt diagnosis and early aggressive therapy. Bilateral emphysematous pyelonephritis is even more rare and is associated with high mortality. We describe a case of a 62-year-old diabetic woman who presented with nonketotic hyperosmolar coma and bilateral emphysematous pyelonephritis caused by klebsiella pneumoniae. diagnosis of bilateral emphysematous pyelonephritis was confirmed by an abdominal computed tomographic scan and microbiologic studies. Our patient was successfully treated using percutaneous catheter drainage and long-term antibiotic therapy.- - - - - - - - - - ranking = 1keywords = gas (Clic here for more details about this article) |
7/38. Small intestine perforation because of capacitive coupling as a cause of abdominal wall gas gangrene and clostridial sepsis after laparoscopic cholecystectomy.The authors present a case report regarding abdominal wall gas gangrene and clostridial sepsis after laparoscopic cholecystectomy. Capacitive coupling was considered to be the most probable cause of small intestine perforation and further complications. Despite intensive treatment, the 69-year-old patient died.- - - - - - - - - - ranking = 5keywords = gas (Clic here for more details about this article) |
8/38. Timing of surgery for enterovesical fistula in Crohn's disease: decision analysis using a time-dependent compartment model.OBJECTIVES: Previous decision analyses of inflam matory bowel diseases (IBD) have used decision trees and markov chains. Occasionally IBD patients present with medical problems that are difficult or even impossible to phrase in terms of such established decision tools. This article aims to introduce modeling by a time-dependent compartment mode and demonstrate its feasibility for decision analysis in IBD methods: A Crohn's disease patient presented with a pelvic abscess and an enterovesical fistula. Being hesitant to operate in an acutely inflamed area, the surgeon recommended that the patient continue antibiotic therapy until the abscess had re solved. The gastroenterologist argued that the patient had already been treated with antibiotics for a prolonged time period and expressed concern that the patient's overall diminished health status would deteriorate by further delay of surgery. The occurrence of fistula, abscess, urinary tract infection, antibiotic therapy, surgical operation, and health-related quality of life were modeled as separate compartments, with time-dependent relationships among them. The simulation was carried out on an Excel spreadsheet. RESULTS: In the model, the surgeon's predictions were associated with rapid resolution of the pelvic abscess under antibiotic therapy and improvement of the patient's health status. The gastroenterologist's predictions resulted in a smaller decline in abscess size and further deterioration of the patient's health while waiting for a definitive treatment. The disagreement between surgery and gastroenterology arose from predicting different time courses for the individual disease events, in essence, from assigning different time constants to the time-dependent influences of the disease model. CONCLUSIONS: The compartment model provides a simple and generally applicable method to assess time dependent-changes of a complex disease. The present analysis also serves to illustrate the usefulness of such models in simulating disease behavior.- - - - - - - - - - ranking = 3keywords = gas (Clic here for more details about this article) |
9/38. Intraabdominal abscess managed successfully via the laparoscopic approach.A rare complication of laparoscopic fundoplication-an intraabdominal abscess located between the fundus and the caudate lobe of the liver-is described. A 41-year-old man had undergone a laparoscopic Nissen-Rossetti fundoplication for longstanding gastroesophageal reflux disease. On the 5th postoperative day, the patient's general condition became worse, and he developed intermittent-remittent fever (40 degrees C), an elevated white blood cell count (WBC), and an accelerated sedimentation rate. Evidence of leakage was excluded by Gastrografin swallow. The diagnosis was finally revealed by means of ultrasound and computed tomography (CT) scan, which showed an intraabdominal fluid collection with an air cap of ~10 cm in diameter situated between the diaphragmatic crura, the caudate lobe of the liver, and the gastric fundus. The location did not allow semi-invasive management of the abscess, such as ultrasound or CT-guided puncture and drainage. On the 8th postoperative day, a laparoscopic exploration was performed utilizing the previous port sites. The adhesions were easily dissected, and evacuation of ~300 ml of white, dense fluid, and lavage and drainage were performed without intraabdominal dissemination of pus. The patient was discharged on the 12th postoperative day free of symptoms. Microbiological examination of the pus showed the presence of peptostreptococcus. The patient remained symptom free. At 8 weeks postoperatively, barium swallow, endoscopy, 24-h pH monitoring, and stationary manometry of the esophagus yielded normal results. Because there was no direct evidence of leakage at the fundus, the development of the abscess was concluded to be due to the use of deep transmucosal stitches rather than seromuscular ones to create the wrap. The nonabsorbable multifilament suture material passing through the entire gastric wall could have facilitated bacterial contamination of the operative field.- - - - - - - - - - ranking = 3keywords = gas (Clic here for more details about this article) |
10/38. Recurrent abscess at site of laparoscopic cholecystectomy port due to spilled gallstones.Spillage of gallstones is common during laparoscopic cholecystectomy and may lead to intra-abdominal abscesses and sinus formation. We describe two patients with recurrent abscess at the site of epigastric port due to presence of large spilled stone in the parietes following laparoscopic cholecystectomy. Removal of the stone led to resolution of symptoms.- - - - - - - - - - ranking = 1keywords = gas (Clic here for more details about this article) |
