1/76. A new technique for intraoperative enteroscopy using a 12-mm trocar.Intraoperative enteroscopy is a valuable method for localizing gastrointestinal bleeding of obscure origin. The insertion and manipulation of an endoscope through an enterotomy, however, may result in significant trauma to the intestinal wall, as well as contamination of the abdominal cavity. We have devised a new technique for the introduction of the endoscope that lessens trauma to the bowel wall and allows a complete enteroscopy with minimal contamination.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
2/76. Treatment of left atrial dissection after mitral repair: internal drainage.Two patients with intraoperative dissection of the entire left atrium after mitral valve repair are presented. Intraoperative transesophageal echocardiography detected left atrial dissection with formation of a large cavity compressing the left atrium. The false lumen was opened and widely connected to the right atrium to perform the decompression. This technique permits the runoff into the low pressure system in case of persisting hemorrhage from the unknown entry, and eliminates the risk of systemic embolization from the cavity.- - - - - - - - - - ranking = 2keywords = cavity (Clic here for more details about this article) |
3/76. Use of the Hasson cannula producing major vascular injury at laparoscopy.Despite the recent demonstration that vascular lesions occur significantly more frequently in patients having closed rather than "open" laparoscopy, there never has been a published case report of injury to the great vessels associated with the open technique of initial access to the peritoneal cavity at laparoscopy. We present the first two such cases reported, along with a brief review of the literature related to such major vascular injuries (MVI) sustained at laparoscopy. Lacking appreciation of aortic anatomy and intraoperative technical factors contribute to the occurrence of these injuries. delayed diagnosis and management contribute to poor outcomes. Secondary injury frequently is associated with MVI at laparoscopy.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
4/76. Posterior hepatic duct injury during laparoscopic cholecystectomy finally necessitating hepatic resection: case report.A case of bile duct injury during laparoscopic cholecystectomy finally necessitating right hepatic lobectomy is reported to re-emphasize the importance of preoperative and intraoperative assessment of the biliary tree. A 47-year-old Japanese woman underwent laparoscopic cholecystectomy for cholecystolithiasis. On postoperative day 5, fever and right hypochondralgia developed, and CT revealed fluid collection at the right hypochondrium. Percutaneous drainage was performed, and subsequent fistulography revealed a communication of the cystic cavity with the right posterior bile duct, which suggested injury of the aberrant hepatic duct. Conservative therapy, including the adaptation of fibrin glue, was performed, but closure of the fistula and cavity was not obtainable. Finally, a right hepatic lobectomy was performed four months after cholecystectomy. In this case, endoscopic retrograde cholangiopancreatography was unsuccessful preoperatively, and intraoperative cholangiography was not done. This case report re-emphasizes that the preoperative and intraoperative examination of the biliary tree is mandatory to avoid bile duct injury.- - - - - - - - - - ranking = 2keywords = cavity (Clic here for more details about this article) |
5/76. Is the loss of gallstones during laparoscopic cholecystectomy an underestimated complication?Laparoscopic cholecystectomy entails an increased risk of gallbladder rupture and consequent loss of stones in the abdominal cavity. Herein we report the case of a 51-year-old male patient, who underwent laparoscopic cholecystectomy 2 years before presentation to our hospital. He had experienced tension sensation and epigastric pain since 4 months postoperatively. A well-defined epigastric mass, which was hard and painful on palpation, was detected and later confirmed by ultrasonography and CT scan.Explorative laparotomy revealed a mass in the area of the gastrocolic ligament,resulting from biliary gallstones in conjunction with a perimetral inflammatory reaction. A review of the literature showed that the incidence of gallbladder lesions during laparoscopy is 13-40%. In order to prevent this complication, meticulous isolation of the gallbladder, proper dissection of the cystic duct and artery, and careful extraction through the umbilical access are required. ligation after the rupture or use of an endo-bag may be helpful. The loss of gallstones and their retention in the abdominal cavity should be noted in the description of the surgical procedure.- - - - - - - - - - ranking = 2keywords = cavity (Clic here for more details about this article) |
6/76. Atherosclerotic disruption of the aortic arch during coronary artery bypass operation.A 70-year-old-man presented with a symptomatic three vessel coronary artery disease and was scheduled for myocardial revascularization. During extracorporeal circulation an intrathoracal bleeding occurred and aortic rupture was suspected. An iatrogenic plaque rupture in the concavity of the aortic arch was found due to cannulation attempts. The aortic arch was grafted in the so-called elephant trunk technique. Thereafter bypass grafts were anastomosed to the stenosed coronary arteries. The patient was discharged from hospital after 2 weeks in good condition.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
7/76. Anesthetic implications of the grey platelet syndrome.PURPOSE: To describe the obstetrical anesthetic care provided to two sisters with a rare qualitative platelet disorder, the grey platelet syndrome (GPS). CLINICAL FEATURES: Both patients manifested thrombocytopenia prior to delivery without previous history of a bleeding diathesis or other abnormal laboratory tests of coagulation function. The first required emergency cesarean section due to fetal bradycardia. Due to the thrombocytopenia and the emergency nature of the procedure, general anesthesia was used. During the C-section, 1.5-2 litres of old blood was noted in the abdominal cavity which was attributed to an old splenic capsular tear of unknown etiology. work-up for the thrombocytopenia revealed large platelets on the peripheral smear with abnormal aggregation on platelet function studies. Electron microscopy of the platelets revealed absent alpha granules, diagnostic of GPS. The second patient, the sister of patient #1, presented in a similar fashion. However, at presentation, the platelet count was 112,000 x m(-3) and spinal anesthesia was provided without complication for Cesarean delivery. The same patient presented for a second delivery during which fetal bradycardia necessitated emergency C-section under general anesthesia. Despite administration of six units of platelets, blood loss was 5,200 mL. Her postpartum course was uncomplicated and she and the infant were discharged home on postoperative day #4. CONCLUSION: The primary concerns for the anesthesiologist looking after patients with qualitative platelet defects are related to defective coagulation which influences the need for perioperative replacement of blood products and limits the use of regional anesthesia.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
8/76. Tension pneumothorax as a complication of video-assisted thorascopic surgery for anterior correction of idiopathic scoliosis in an adolescent female.STUDY DESIGN: This case report illustrates the occurrence of intraoperative tension pneumothorax, a previously unreported complication occurring during anterior instrumentation for correction of scoliosis by video-assisted surgery. OBJECTIVES: To demonstrate a consequence of overadvancement of a Steinmann pin (guide wire). SUMMARY OF BACKGROUND DATA: Although intraoperative tension pneumothorax is admitted to be a theoretical complication of video-assisted surgery for anterior correction of idiopathic scoliosis, there has yet to be a case reported in the literature. This report presents the first case of this complication. methods: A 13-year-old girl who had right thoracic scoliosis with a curve measuring 54 degrees underwent video-assisted surgery discectomy and anterior spinal fusion with instrumentation of T5 through T11. Single-lung ventilation had been achieved with a double-lumen tube and the right lung was deflated. After approximately 4.5 hours of complication-free surgery, intraoperative fluoroscopy showed an approximately 2-cm overadvancement of a guide wire into the opposite hemithorax. Approximately 5 minutes after the overadvancement was corrected, the patient experienced a gradual increase in heart rate and a corresponding gradual decrease in oxygen saturation and both systolic and diastolic blood pressures. Approximately 35 minutes later, it was determined that the patient had sustained a tension pneumothorax of the left hemithorax. RESULTS: The patient underwent urgent partial reinflation of the right lung and a tube thoracostomy of the left thoracic cavity. vital signs quickly returned to stable levels, and the left lung easily reinflated with the chest tube suction. The patient remained stable after the procedure was resumed (by right lung deflation). The remainder of the surgery and the postoperative course were uneventful. CONCLUSIONS: Although video-assisted surgery continues to gain popularity in the management of spinal deformities, the surgical team must be certain to pay meticulous attention to detail throughout the procedure. The early detection and treatment of complications can be life-preserving.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
9/76. Intraperitoneal abscess after an undetected spilled stone.gallbladder perforation with loss of calculi in the abdomen is frequent during laparoscopic cholecystectomy and can cause serious late complications. We report on a 65-year-old woman who underwent laparoscopic cholecystectomy for gallbladder empyema, during which a stone spilled into the peritoneal cavity. The spilled gallstone was not noticed during the initial operation. Three months later, she reported left upper quadrant pain of recent onset without associated symptoms such as fever, nausea, or weight loss. On examination, a palpable 2-cm tender subcutaneous mass was found. Abdominal ultrasound demonstrated an incarcerated hernia, and computed tomography (CT) scan showed an intraperitoneal abscess located in the back of the anterior abdominal wall in the left upper quadrant, which contained a recalcification figure. The patient was brought to surgery, at which time an incision was made over the mass. A chronic abscess in the back of the abdominal wall, also spreading into the subfascial space, was drained, and purulent material was obtained with a large stone, 2.8 cm in diameter, which had become lodged in the rectus abdominis after an undetected stone spillage during laparoscopic cholecystectomy. The patient continued receiving antibiotic treatment for 7 days, recovered well, and was discharged 7 days after drainage of the abscess.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
10/76. Delayed recognition of inadvertent gut injury during laparoscopy.Bowel injuries, which may occur as a result of the insertion of an insufflation needle or trocar, are a rare complication of laparoscopy. They are generally recognized either immediately or a few days after the operation. We present a case of laparoscopic perforation of the small intestine in a patient who had undergone previous pelvic surgery for an ovarian carcinoma. On ultrasound (US), the patient had multiple hepatic lesions resembling hepatic metastases. To confirm the diagnosis, laparoscopy with guided liver biopsy was performed on the grounds that this procedure is regarded as more appropriate than CT- or US-guided hepatic biopsy. Veress needle and trocar insertion were performed at a proper distance from the abdominal scar. However, the abdominal cavity was not visible after the trocar's insertion due to the unexpected presence of adhesions. This precluded the continuation of the procedure. In the following days, the patient experienced only mild abdominal discomfort. However, 2 weeks after laparoscopy, the patient presented signs of peritoneal reaction and underwent laparotomy. Adhesion-fixing jejunal loops to the anterior abdominal wall were discovered at the site of the trocar puncture. Moreover, two hiatuses of these loops were observed and sutured. The follow-up was uneventful. As this case illustrates, laparoscopic bowel injuries remain an unpredictable event. Recognition of this complication may occur several days after the procedure, as the tamponating effect of adhesions on the jejunal hiatus delays the involvement of the peritoneum.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
