450 successive celioscopic cholecystectomies (May, 1990-April, 1992) are reported for 312 cases of uncomplicated gallstone (69%) operated electively and 138 cases operated in emergency, including 120 cases of acute cholecystitis, 17 cases of biliary pancreatitis and 1 case of angiocholitis. Immediate conversion into laparotomy was required in 10 cases (2.2%) either for technical reasons (1.1%) or because of lithiasis of the common bile duct (1.1%). The stay in hospital lasted an average of 2.2% days for elective admission and 3.3 days for emergent admission. The average operating time was 65 minutes (75 minutes until May, 1991, and 55 minutes between May, 1991 and April, 1992). Preoperative retrograde cholangiography was performed in 67 cases and intraoperative cholangiography in 16 cases. Second surgery was required for suture in one case because of cholerrhagia in a secondary duct of the gallbladder bed. This cholerrhagia would not have been amenable to simple aspiration. One patient (0.2%) died of myocardial infarction at D + 10. Complications include 4 cases of pulmonary embolism, 3 cases of cystic biliary fistula without second surgery and 4 cases of umbilical hernia. A more peculiar case is that of a patient admitted 5 months after surgery for gangrenous acute cholecystitis. This patient was admitted for fever and epigrastric pain. He had a very low-flow duodenocutaneous fistula of uncertain origin. This patient was not operated again. This may not be a complication connected to celioscopic surgery. Celioscopic cholecystectomy is superseding conventional cholecystectomy. Surgeons' efforts should strive at eliminating operative errors, reducing postoperative morbidity, improving techniques and instruments, teaching celioscopic surgery and extending its indications to other intraabdominal operations.

Radical prostatectomy is a useful procedure for the treatment of prostate cancer limited to the gland; however, failure may occur as a result of the immediate or delayed complications of surgery, or to disease recurrence related to incomplete tumour excision. Seventy-nine radical prostatectomies were performed between April 1985 and August 1991 in patients with prostate cancer (primarily stage B1) who averaged 63 years of age. Immediate post-operative complications included vesicocutaneous fistulae, cystic lymphangiomas, abdominal wall abscesses, extraperitoneal haematoma, acute cholecystitis, and enterocutaneous fistula. Massive pulmonary embolism accounted for 2 deaths. Of the 77 surviving patients followed up for an average of 34 months, 79.2% (61) were continent, 15.6% had stress-related incontinence or severe incontinence and 5.2% were lost to follow-up. Sexual potency was preserved in 13 of the 33 patients (39%) who were pre-operatively potent. A favourable outcome as defined by no recurrence was seen in 69 patients (87.3%). Four patients (5.1%) are living with recurring prostatic cancer and 1 patient has died of the disease 46 months after surgery.

Seven cases of the Curtis-Fitz-Hugh syndrome diagnosed over a six month period are reviewed with particular reference to the widely ranging modes of presentation. All presented as acute surgical emergencies but unlike other series, right upper quadrant pain was the presenting symptom in only one case. Right upper quadrant pain nonetheless, featured to a variable extent in all cases, being relatively shortlived in three. Conditions mimicked included left renal colic, acute appendicitis, pulmonary embolism, acute cholecystitis, chronic cholecystitis and urinary tract infection. In five cases symptoms dated back to a difficult or complicated termination of pregnancy and in one case a hysterectomy had been performed twelve years previously at which time the patient had documented evidence of pelvic inflammation. Diagnosis was made laparoscopically and all symptoms responded satisfactorily to a four week course of tetracycline.

Radionuclide diagnostic imaging is an important adjunct to the diagnosis and treatment of several conditions that present to the emergency department. The emergency physician should be able to properly apply these tests. A normal radionuclide perfusion lung scan can reliably rule out pulmonary embolism. The use of the radionuclide ventilation lung scan may help interpretation of a perfusion lung scan that is of intermediate probability for pulmonary embolism. A radionuclide venogram of the lower extremities is both sensitive and accurate for detecting the presence of deep venous thrombosis. A radionuclide testicular scan is invaluable in the workup of the acute scrotum, as long as the test is available in a timely manner and the diagnosis has not been established by another means. A multiple-gated acquisition cardiac scan can help make the diagnosis of cardiac contusion after other causes of cardiac instability have been corrected. The renal radionuclide scan is useful in the workup of obstructive uropathy, especially if intravenous pyelography is contraindicated. The hepatobiliary nuclear scan is able to help differentiate acute cholecystitis from other causes of right upper quadrant pain. Proper and timely use of these tests can prevent serious sequelae from a missed diagnosis, and in some cases eliminate the need for invasive tests, dangerous treatment, or even exploratory surgery when it is unwarranted.

The development of laparoscopic cholecystectomy is only justified if it can ensure the good results obtained by laparotomy. The purpose of this work is to study all complications which occurred in a homogeneous group of patients. From May 1988 to January 1993, we operated on 2006 patients by laparoscopy (724 men and 1282 women) with a mean age of 50.6 years. Signs of stones in the common bile duct were noted in 4.1% and acute cholecystitis was detected in 12.5%. A conversion to normal laparotomy was necessary in 2.1% of patients. All complications were systematically investigated restrospectively in any patient hospitalised for more than five days. Residual stones in the common bile duct were not taken into consideration when they were not complications obviously related to the operation. We observed five intraoperative complications (4 hemorrhages, 1 ileum puncture) and 40 postoperative complications (25 non biliary and 15 biliary). The 25 non biliary complications consisted of: 1 death by pulmonary embolism, 9 hemorrhages, 4 cases of acute pancreatitis, 4 subphrenic abscesses, 2 colon punctures, 2 parietal complications, 1 ulcer perforation, 1 myocardial infarction and 1 phlebitis. The 15 biliary complications consisted of: 3 lateral punctures of the common bile duct, 9 fistulas of the cystic duct (4 with a residual stone in the common bile duct and 5 without), 2 punctures of an abnormal right hepatic duct, one of which was treated by "Roux en Y loop" intestinal diversion, and a late stenosis of the common bile duct.(ABSTRACT TRUNCATED AT 250 WORDS)

The treatment of biliary lithiasis has changed during the past 20 years. Cholecystectomy remains the gold standard for cholelithiasis, but many options are available for calculi of the common bile duct. Among them are surgical open or laparoscopic choledochotomy, biliary-enteric anastomosis, transduodenal sphincterotomy (TDS), endoscopic sphincterotomy. With the aim to describe the current place of TDS, we reviewed the patients operated on in our department between 1976 and 1992. We found 78 patients with a mean age of 58 years (26-89 years). 34 (43%) of them had acute cholecystitis, with 26 being operated on urgently. 47 (60%) were jaundiced, 15 (19%) had pancreatitis and 12 (15%) had cholangitis before operation. Indications for TDS have been impacted stone or absence of progression of the contrast medium on intraoperative cholangiography in 71 patients (91%). 3 patients died (1 pulmonary embolism, 1 sepsis of pulmonary origin, 1 MOF syndrome complicating preoperative necrotizing pancreatitis). 30 patients (38%) had complications, of which 20 were directly related to TDS. Hemorrhage occurred in 4 cases, and resolved spontaneously without transfusion. Hyperamylasemia occurred in 17 instances, but clinical pancreatitis developed in only 1 case, with complete resolution. 1 duodenal fistula healed after conservative therapy. No death is attributable directly to TDS. Today, the importance of endoscopic sphincterotomy is increasing. This retrospective study shows that TDS, if performed with caution, does not increase the operative risks even in emergent operations. During surgical exploration of the common bile duct, TDS is indicated to remove an impacted stone, or as a bilio-enteric anastomosis if multiple stones are present with a thin common duct.(ABSTRACT TRUNCATED AT 250 WORDS)

From November 1990 to April 1994 we attempted laparoscopic cholecystectomy (LC) in 1,788 consecutive patients. The intraoperative findings related to gallbladder's pathology were as following: chronic cholecystitis in 792 patients (44.3%), simple cholecystolithiasis in 760 (42.5%), acute cholecystitis in 98 (5.5%), hydrops in 44 (2.5%), empyema in 38 (2.1%), gangrenous cholecystitis in 12 patients, acalculous cholecystitis in 20 patients, polyps in 11 patients, adenomyomatosis in 9 patients, and gallbladder's carcinoma in 4 patients. Although we had a considerable number of cases with severe inflammation and/or dense adhesions the conversion rate to open surgery was relatively low (2.5%). There was no procedure-related mortality and no common bile duct injury. Postoperative complications occurred in 58 patients (3.2%). Bile leak was present in 19 patients, retained bile duct stones in 8, severe bleeding in 6, mild pancreatitis in 4, pulmonary embolism in 1, cerebral bleeding in 1, wound infection in 6, abdominal wall hematoma in 4, and umbilical incisional hernia in 2; 7 patients presented other minor complications. The mean postoperative hospital stay of our patients was 1.8 days (range 1-12 days). Adequate measures to prevent intraoperative accidents, meticulous technique, and full maintenance of the equipment are among the most important factors in keeping a low conversion and complication rate in the patients undergoing LC.

BACKGROUND: This study concerns 33 patients treated for morbid obesity with the procedure proposed by Scopinaro. Results are reviewed retrospectively in terms of complication rates. METHODS: The group consisted of ten men and 23 women with a mean age of 34 years (range 20-51 years), and a mean BMI of 49.5 kg/m(2) (range 37-77). Adequate attempts at medical management had failed repeatedly. The operative procedure involved a 2/3 partial gastrectomy and biliopancreatic diversion by Roux-en-Y reconstruction 50 cm before the ileocecal valve. In one patient, a cholecystectomy was added. RESULTS: The mean weight loss after 6 months was 18.9% of the initial weight, with mean BMI 41 kg/m(2) (range 29-60). Early complications included four wound infections (15%), while two patients complained of an early dumping syndrome (6%), treated by dietary measures. There were no respiratory infections and no pulmonary embolism, likely as a result of the thoracic epidural anesthesia and high doses of prophylactic heparin used. There was no mortality. As to late complications, nine patients complained of diarrhea due to bacterial overgrowth (27%) and were treated with antibiotic therapy. There were five incisional hernias (15%). Five patients had a peptic ulcer (15%) and required medical treatment. Two patients had acute cholecystitis (6%). One patient had an afferent loop obstruction (3%), requiring reoperation. CONCLUSIONS: Overall, this series of intestinal diversion procedures by the method of Scopinaro had a larger complication rate than generally accepted.

The goal of this study was to develop and validate text-mining algorithms to automatically identify radiology reports containing critical results including tension or increasing/new large pneumothorax, acute pulmonary embolism, acute cholecystitis, acute appendicitis, ectopic pregnancy, scrotal torsion, unexplained free intraperitoneal air, new or increasing intracranial hemorrhage, and malpositioned tubes and lines. The algorithms were developed using rule-based approaches and designed to search for common words and phrases in radiology reports that indicate critical results. Certain text-mining features were utilized such as wildcards, stemming, negation detection, proximity matching, and expanded searches with applicable synonyms. To further improve accuracy, the algorithms utilized modality and exam-specific queries, searched under the "Impression" field of the radiology report, and excluded reports with a low level of diagnostic certainty. Algorithm accuracy was determined using precision, recall, and F-measure using human review as the reference standard. The overall accuracy (F-measure) of the algorithms ranged from 81% to 100%, with a mean precision and recall of 96% and 91%, respectively. These algorithms can be applied to radiology report databases for quality assurance and accreditation, integrated with existing dashboards for display and monitoring, and ported to other institutions for their own use.

Various radiopharmaceuticals are available for imaging pediatric patients in an acute care setting. This article focuses on the common applications used on a pediatric patient in acute care. To confirm the clinical diagnosis of brain death, brain scintigraphy is considered accurate and has been favorably compared with other methods of detecting the presence or absence of cerebral blood flow. Ventilation-perfusion lung scans are easy and safe to perform with less radiation exposure than computed tomography pulmonary angiography and remain an appropriate procedure to perform on children with suspected pulmonary embolism as a first imaging test in a hemodynamically stable patient with no history of lung disease and normal chest radiograph. (99m)Tc pertechnetate scintigraphy (Meckel's scan) is the best noninvasive procedure to establish the diagnosis of ectopic gastric mucosa in Meckel's diverticulum. Hepatobiliary scintigraphy is the most accurate diagnostic imaging modality for acute cholecystitis. (99m)Tc-dimercaptosuccinic acid scintigraphy is the simplest, and the most reliable and sensitive method for the early diagnosis of focal or diffuse functional cortical damage. Bone scintigraphy is a sensitive and noninvasive technique for the diagnosis of bone disorders such as osteomyelitis and fracture. Of recent, positron emission tomography imaging using (18)F-NaF has been introduced as an alternative to bone scintigraphy. (18)F-fluorodeoxyglucose-positron emission tomography has the potential to replace other imaging modalities, such as the evaluation of fever of unknown origin in pediatric patients, with better sensitivity and significantly less radiation exposure than gallium scan.
