Anaphylactic reaction to aprotinin despite negative ocular sensitivity tests.

A man with a history of pancreatitis was given aprotinin intravenously just before endoscopic retrograde pancreatography. Despite negative sensitivity tests with aprotinin eye drops he developed a profound anaphylactic reaction on intravenous administration of the drug. Ocular sensitivity tests may not predict severe anaphylactic reactions to intravenous aprotinin.     

Combined use of brushing cytology and endoscopic retrograde pancreatography for the early detection of pancreatic cancer

Seventy-two cases of pancreatic cancer were examined by brushing cytology combined with endoscopic retrograde pancreatography. The results of this combined method were better than those reported for the exfoliative cytologic study of pancreatic fluid. The method detected a minute cancer of the main pancreatic duct that was not detected with any other method. The cells obtained by this technique had very well-preserved cytoplasm and nuclear chromatin, which facilitated making a correct diagnosis. Though this method can be applied only to the main pancreatic duct, it is effective for the diagnosis of ductal cell carcinoma, especially those located at the head of the pancreas, which is the most common site for pancreatic cancer. It is a safe procedure, with no complications seen in this series. The differentiation of carcinoma cells from the benign atypical cells of chronic pancreatitis is illustrated and emphasized.     

Early cancer in congenital choledochal cyst

We report a case of 35-yr-old woman with early cancer in congenital choledochal cyst. She had a five-year history of intermittent right upper abdominal pain and intermittent jaundice. In this period she had a few abdominal ultrasonographies, but the cholelithiasis had not been found. Now, she was admitted to our hospital because she felt right upper abdominal pain with slight jaundice and subfebrile temperature four weeks ago. Abdominal ultrasonography showed enormous dilatation of the common bile duct, which was suspected as choledochal cyst. Computed tomography and endoscopic retrograde cholangiopancreatography revealed cystic dilatation of extrahepatic bile duct. An anomalous pancreaticobiliary junction was not found. The patient with congenital choledochal cyst was operated on. The excision of choledochal cyst was done with hepaticojejunostomy Roux-en-Y. There were no lymph nodes metastases. On the central part of choledochal cysts mucosa, it was shown a white plain area of thickness 0.3 cm and 0.8 cm in diameter. Histologically it was well-differentiated tubular adenocarcinoma, which was limited to the mucosa and which did not penetrate to other parts of the bile duct wall. From our knowledge, only small number cases of early cholangiocarcinoma in choledochal cyst were until now reported. Nearly eight years after the operation the patient feels very well, and has optimal working ability (Karnofsky 100%).     

Rational sequence of tests for pancreatic function.

Of 144 patients with suspected pancreatic disease in whom a 75Se-selenomethionine scan was performed, endoscopic retrograde pancreatography (ERP) was successful in 108 (75%). The final diagnosis is known in 100 patients and has been compared with scan and ERP findings. A normal scan reliably indicated a normal pancreas, but the scan was falsely abnormal in 30%. ERP distinguished between carcinoma and chronic pancreatitis in 84% of cases but was falsely normal in five patients with pancreatic disease. In extrahepatic biliary disease both tests tended to give falsely abnormal results. A sequence of tests to provide a rapid and reliable assessment of pancreatic function should be a radio-isotope scan, followed by ERP if the results of the scan are abnormal, and a Lundh test if the scan is abnormal but the findings on ERP are normal.     

Symposium on diarrhea. 3. Investigation of chronic diarrhea.

The practical approach to the investigation of diarrhea must be logical and based on anatomic considerations. The site of the underlying disorder may be determined by the clinical picture, and the logic of investigation will be influenced by the history. Important specific investigation in a case of colonic diarrhea include a careful rectal examination, stool inspection, sigmoidoscopy, rectal biopsy and barium enema study. Colonoscopy has been used, but its role has yet to be defined. In a case of small-bowel steatorrhea or diarrhea quantitative chemical estimation of the daily output of stool fat is useful, and to this investigation is added a small-bowel radiograph series and, if the radiographic findings are abnormal, small-bowel biopsy. Other investigations for small-bowel disease may include the breath test with carbon-14-labelled glycocholic acid, the lactose tolerance test, duodenal aspiration for giardiasis, analysis of serum immunoglobulins and, on occasion, isolation of vasoactive intestinal polypeptide hormone (which may aid the diagnosis of functioning tumours of the pancreas or small bowel). Investigations for pancreatic steatorrhea include abdominal radiography, performance of the secretin test and testing of the response to pancreatic replacement therapy. In some patients it may be useful to use endoscopic retrograde cholangiopancreatography to differentiate pancreatic carcinoma and chronic pancreatitis.     

阑尾残株炎9例的临床观察

目的：总结阑尾残株炎的病因、诊断方法、预防和治疗措施,为临床提供更多的参考依据。方法：回顾性分析我院2011年1月～2013年1月收治的9例阑尾残株炎患者的临床资料,并查阅相关文献,总结阑尾残株炎的病因和诊疗方法等。结果：阑尾残端过长（〉1cm）是导致阑尾残株炎发生的主要原因。结合血常规、钡剂灌肠透视、CT、彩超等检查,必要时行腹腔镜探查可确诊阑尾残株炎。及时行手术切除阑尾残株是阑尾残株炎主要治疗方法。本组5例患者行传统开腹阑尾残端切除术（残端双重结扎,保留残端0．2～0．3cm）,2例行腹腔镜阑尾残端切除术（钛夹夹闭阑尾残端,保留阑尾残端0．2～0．3cm）,2例行部分盲肠切除术,回盲部留置引流管。2例患者出现切口感染,9例患者均痊愈。结论：预防阑尾残株炎的主要措施是是尽量完善阑尾切除手术。对已行阑尾切除术的患者再次出现右下腹部疼痛时等类似阑尾炎症状时,临床医生应考虑阑尾残株炎的可能,进一步行钡剂灌肠透视检查及腹部超声等辅助检查,必要时行腹腔镜腹腔探查以确诊,并应根据患者具体情况及时行手术切除阑尾残株。     

Absceso tiroideo. Serie de casos y revisión de la literatura

Thyroid abscess is rare in children but the presence of previous thyroid disease, and congenital remanants such as a pyriform sinus fistula, are predisposing factors. The classical presentation consists of fever, cervical pain and a painful mass. The diagnosis is confirmed through clinical findings, and by diagnostic imaging (ultrasound and computerized axial tomography). A barium swallow must be performed in order to detect a fistula and to consider surgical drain. We present the cases of thyroid abscess in five patients who were admitted in four medical centers (Fundación Cardioinfantil, Hospital Universitario San Ignacio, Clínica infantil de Colsubsidio and Hospital de la Misericordia) in Bogotá, Colombia between 2000 and 2010.     

Diagnosis and management of 528 abdominal aortic aneurysms.

Between 1960 and 1979 528 patients with abdominal aortic aneurysms presented to the university department of surgery. Of these, 222 (42%) were elective cases, 72 acute (14%), 174 had ruptured (33%), and four had had a spontaneous aortoduodenal fistula (1%). In all these patients resections were undertaken, but in another 56 patients (11%) the aneurysm was not resected. A review of these cases showed that 91% had symptoms at their first presentation; abdominal pain and backache being most common. The diagnosis could be established in 91% by the presence of pulsatile abdominal mass on clinical examination. The operative mortality for elective resection was 8%, for acute 19%, for ruptured cases 42%, and for spontaneous aortoduodenal fistula 50%. After successful resection the overall five-year survival was 65% by the life table method, and there was no significant difference between elective, acute, and ruptured cases. This five-year survival after resection compares favourably with the expected 76% survival of a similar normal population, and was considerably better than that for conservatively treated patients. As most cases have symptoms, and diagnosis may be established easily by routine physical examination in 91%, the prognosis for this condition could be considerably improved by increased awareness of its existence and early referral for treatment as an elective surgical procedure.     

Cytologic findings in noninvasive intraductal papillary-mucinous carcinoma of the pancreas. A report of two cases

BACKGROUND: Intraductal papillary-mucinous carcinoma of the pancreas is a new diagnostic term proposed by the 1996 World Health Organization classification of the exocrine pancreas. So far, there have been only a few reports concerning its cytologic findings, especially in noninvasive cases. CASES: The clinical and cytohistologic findings in two cases of noninvasive intraductal papillary-mucinous carcinoma of the pancreas were reviewed. Cytologic specimens were obtained from pure pancreatic juice in the dilated main pancreatic duct during the operation (case 1) and during endoscopic retrograde pancreatography (ERP) (case 2). Both cases showed three-dimensionally or individually scattered tumor cells with an increased nuclear/cytoplasmic ratio and prominent nucleoli. CONCLUSION: Our cases suggest that pancreatic juice cytology during ERP or surgery is useful in diagnosing pancreatic cancers and that it may detect noninvasive intraductal papillary-mucinous carcinoma of the pancreas.     

Pleural Effusion with Pancreaticopleural Fistula

Three patients with pleural effusion were found to have pancreaticopleural fistulas passing through an opening in the diaphragm are reported. In one case the effusion was purulent and originated from an abscess of the pancreas. Retrograde pancreatography during operation defined the course of the fistula. In two other cases the fistula was demonstrated by radiography after intrapleural injection of contrast medium. The diagnostic importance of injecting contrast medium early into the pleural cavity in cases of effusion rich in amylase, before lung expansion obscures the fistula, is emphasized. Cases of pancreaticopleural fistula may be commoner than supposed.     

Current treatment options for penile fractures

The diagnosis of "penile fracture" describes the traumatic rupture of the tunica albuginea of an erect penis. Penile fractures typically occur when the engorged penile corpora are forced to buckle and literally "pop" under the pressure of a blunt sexual trauma. Patients typically describe immediate detumescence, severe pain, and swelling as a result of the injury. Prompt surgical exploration and corporal repair is the most efficacious therapy. Although a majority of cases can be diagnosed from the history and physical examination alone, radiographic studies, including retrograde urethrography and corporal cavernosography can aid in the diagnosis of unusual cases.     

Recognition and management of embolism to the superior mesenteric artery

Two cases of superior mesenteric arterial embolism are presented. The diagnosis should be suspected when severe abdominal pain develops suddenly in a patient with a cardiac arrhythmia or a recent history of myocardial infarction. Further support for the diagnosis is given by the finding of a poor peripheral circulation and a paucity of abdominal physical signs. The value of arteriography is questionable except to distinguish between thrombosis and embolism. The importance of early laparotomy as a diagnostic and life-saving measure is emphasized.     

Acute suppurative thyroiditis in appearance of unusual neck mass

We report on three adult cases of acute suppurative thyroiditis due to infection through a piriform sinus fistula. In these cases, the lesion did not exhibit the clinical symptoms characteristic of acute suppuration, but appeared as an unusual neck mass. Repeated barium meal roentgenograms, however, demonstrated the internal fistula in two of the three cases. Acute suppurative thyroiditis may not be so rare even in adults. When acute suppurative thyroiditis occurs in adults with scanty symptoms of acute suppuration, the piriform sinus fistula could easily go undetected. Recognition of acute suppurative thyroiditis in adults per se seems to be important for correct diagnosis.     

Barium swallows after free jejunal transfer: should they be performed routinely?

Fistula formation after free jejunal transfer for pharyngoesophageal reconstruction is a serious complication with potentially critical consequences. Barium swallow is used postoperatively to check for anastomotic competence before feeding but has been unreliable as a predictor of leak at our institution. The objective of this study was to evaluate the role of routine postoperative barium swallow in 41 consecutive jejunal transfers. Thirty-nine patients who underwent 41 consecutive free jejunal transfers had a routine barium swallow performed between postoperative days 12 and 17. Radiologic findings and clinical outcome were evaluated and correlated. All barium swallows were reviewed by a single experienced radiologist in a blinded fashion. One total and one partial flap failure necessitated a second free jejunal transfer. Pharyngocutaneous fistulae developed after nine free jejunal transfers, of which the barium swallow was normal in four (44 percent) and showed a leak in five (56 percent). In the 32 free jejunal transfers with no clinical leaks, 6 (19 percent) had radiologic leakage of contrast. Thus, barium swallow was normal in 30 patients and showed leakage in 11 patients. Normal barium swallow correlated with uncomplicated clinical course in 26 of 30 cases. In the remaining four cases (13 percent), however, a delayed fistula developed, which was secondary to flap necrosis in one case (negative predictive value 87 percent). On the other hand, radiologic leaks corroborated clinical fistula in 5 of 11 cases (45 percent), whereas no fistula developed in 6 cases (positive predictive value 46 percent). Of the five patients with clinical fistulae, four had early leaks (within 1 week), and the barium swallow did not provide additional information. The fifth patient developed a delayed leak 2 weeks after the barium swallow. Review of these barium swallows at the time of this study reversed the initial report of leakage in three patients, improving the predictive value to 63 percent. These patients had an uncomplicated clinical course. The positive predictive value of clinical assessment alone was 63 percent. We conclude that barium studies following free jejunal transfers can be difficult to interpret, but an experienced radiologist can improve their accuracy. A normal barium swallow, however, does not ensure an uneventful clinical course. Similarly, radiologic leaks do not imply a clinical complication of fistula. Clinical judgment should therefore be exercised in initiating oral intake after free jejunal transfer. Barium swallow should be used only as an adjunct to aid in patient management.

Radiation treatment for refractory endometriosis: a 38-year-old female presenting with vaginal bleeding

BackgroundEndometriosis is typically managed with a medical or surgical approach, though some patients have medically refractory disease and are poor surgical candidates.Case presentationA 39-year-old woman presented to our facility with uncontrolled bleeding and pain from an endometriotic mass at the vaginal cuff. She had a history of abdominal hysterectomy with bilateral salpingo-oophorectomy, now with medically refractive and inoperable disease due to prior history of vesicovaginal fistula. We prescribed 30 Gy in 10 fractions with 10 MV and 18 MV photons to the target. At follow-up our patient reported a complete resolution of bleeding and pelvic pain.ConclusionRadiation treatment can be an effective treatment for refractory endometriosis.     

A Case of Fasciola hepatica Infection Mimicking Cholangiocarcinoma and ITS-1 Sequencing of the Worm

Fascioliasis is a zoonotic infection caused by Fasciola hepatica or Fasciola gigantica. We report an 87-year-old Korean male patient with postprandial abdominal pain and discomfort due to F. hepatica infection who was diagnosed and managed by endoscopic retrograde cholangiopancreatography (ERCP) with extraction of 2 worms. At his first visit to the hospital, a gallbladder stone was suspected. CT and magnetic retrograde cholangiopancreatography (MRCP) showed an intraductal mass in the common bile duct (CBD) without proximal duct dilatation. Based on radiological findings, the presumed diagnosis was intraductal cholangiocarcinoma. However, in ERCP which was performed for biliary decompression and tissue diagnosis, movable materials were detected in the CBD. Using a basket, 2 living leaf-like parasites were removed. The worms were morphologically compatible with F. hepatica. To rule out the possibility of the worms to be another morphologically close species, in particular F. gigantica, 1 specimen was processed for genetic analysis of its ITS-1 region. The results showed that the present worms were genetically identical (100%) with F. hepatica but different from F. gigantica.     

Prevention of pancreatic reactions by bolus somatostatin administration in patients undergoing endoscopic retrograde cholangio-pancreatography and endoscopic sphincterotomy

Mild pancreatitis is a common complication of endoscopic retrograde cholangio-pancreatography (ERCP) and endoscopic sphincterotomy. Knowing that a bolus injection of natural somatostatin (SRIF) dramatically reduces pancreatic secretion, a study was conducted in 33 subjects undergoing invasive diagnostic procedures. A placebo (n = 16) or SRIF (n = 17; 4 micrograms/kg) were injected before cannulation. Enzymatic rise was observed in 16 (94%) subjects receiving placebo and in 8 (50%) injected previously with SRIF. In the former group 65% reported abdominal pain whereas only 19% had this complaint in the SRIF series. Results suggest that a bolus injection of SRIF may attenuate pancreatic irritation caused by diagnostic procedures or sphincterotomy.     

An incidental case of human Heterophyes nocens infection diagnosed by sectional morphology in a biopsy specimen of the small intestine.

A case of human infection with Heterophyes nocens (Heterophyidae) was incidentally found in a biopsy specimen of the Meckel's diverticulum at the upper part of the small intestine. The patient was a 58-year-old man living in a rural area of Talsonggun, Kyongsangbuk-do. He had gastrointestinal symptoms such as epigastric pain, indigestion, and abdominal discomfort for 3 months, and severe diarrhea, abdominal pain, and vomiting for about 1 month before hospitalization. Endoscopy of the upper part of the small intestine revealed a Meckel's diverticulum, and it was excised and histopathologically examined. Three adult flukes were incidentally found sectioned in the mucosa, and they were identified as H. nocens. The patient had a history of eating raw mullets at a fish market in Pusan 6 months ago, and the mullets were presumed to be the source of infection. This case brings a considerable interest in that specific diagnosis of heterophyid infections could be done by sectional morphology of the worms.
