Ephiphrenic esophageal diverticulum is rare and usually is a pulsion-type pseudodiverticulum that occurs in association with motility disorders of the esophagus. We report a 35-year-old man with tubercular lymphadenitis causing true traction type of epiphrenic diverticulum. Esophageal diverticulectomy and esophagomyotomy was done; he is doing well on antitubercular drugs. 相似文献

AIM: Retrospective analysis of experience with management of external duodenal fistula (EDF) without using total parenteral nutrition (TPN). METHOD: Medical records of 31 patients with EDF following closure of duodenal ulcer perforation, treated over a 7-year period (1994-2001), were studied. Twenty-one patients (68%) had evidence of sepsis at presentation or during the course of treatment. None could afford TPN for optimum time. All patients received hospital-based enteral nutrition through nasojejunal tube, besides supportive medical treatment and/or surgery. Peritonitis or failure to insert nasojejunal tube for enteric alimentation led to early surgery. RESULTS: Two patients died of septicemia and multi-organ failure within 48 hours of admission. Fourteen patients (48.3%) initially received conservative treatment (Group I); six of them later required surgery. Fifteen patients (51.7%) underwent early surgery due to peritonitis (n=9) or failure to establish enteral feeding (n=6) (Group II); wound infection, intra-abdominal abscess and septicemia were more common in these patients than those in Group I. Survival rate was higher in Group I than in Group II (86% versus 40%; p< 0.05). Septicemia and gastrectomy were the independent factors associated with high mortality. CONCLUSIONS: EDF can be satisfactorily managed without TPN. Successful placement of enteral feeding line, supportive treatment and delayed surgery can achieve survival in 85% of patients. Minimum intervention is recommended when early surgery is performed in peritonitis or to establish enteral feeding line. 相似文献

Diltiazem has been extensively studied in the treatment of chronic anal fissures, but efficacy in clinical practice is not
fully established. The aim of the present study was to evaluate the safety and efficacy of topical application diltiazem in
observational studies as well as in controlled clinical trials in the treatment of chronic anal fissures. A systematic literature
search was carried out from 1966 to 31 December, 2007 on PubMed, Medline, Embase and Cochrane database, using the appropriate
search words. We found six observational studies with 392 patients and five controlled clinical trials with 289 patients in
which topical diltiazem treatment was given. Efficacy was found to be very high in observational studies (56.88%), whereas
it was found to be modest in controlled clinical trials (29.41%). In observational studies, most of the patients reported
complete healing of fissures within 6–12 weeks, whereas in controlled trials healing was reported within 8 weeks, with tolerable
adverse effects of diltiazem. On the basis of the above studies, it can be concluded that topical application of diltiazem
is useful in the treatment of chronic anal fissure, but to fully establish its efficacy, larger prospective double-blind study
is required in the near future. 相似文献

Laparoscopic Heller cardiomyotomy and Dor fundoplication is the surgical procedure of choice for esophageal achalasia. The aim of our study was to investigate the clinical outcome and safety of laparoscopic Heller–Dor procedure performed by using Hook electrocautery and as a teaching module for advanced laparoscopic surgery. Between January 2005 and December 2010, 25 consecutive patients with achalasia underwent laparoscopic Heller–Dor operation by a single surgeon. All the patients received upper gastrointestinal series (barium swallow), esophagogastroscopy, and esophageal manometry to exclude esophageal carcinoma and to confirm the diagnosis. All the patients were operated by laparoscopic modified Heller myotomy with Dor fundoplication by using hook electrocautery. Among 25 operated patients, 14 were male and 11 were female with a median age of 43 years (range 18–72 years). The mean operative time was 93.3 min (range 50–50 min), the mean operative blood loss was 90 ml (range 40–200 ml), the median time to oral feeding was 2 days (2–4 days), and the median hospital stay was 4 days (4–7 days). There was no conversion to open surgery. Intraoperative mucosal perforation was encountered in three patients and was repaired in all of them by laparoscopic suture. All the patients had an uneventful recovery without postoperative complication and had excellent clinical response (96 %) during follow-up. Laparoscopic Heller–Dor operation using hook electrocautery is safe, inexpensive, and effective treatment for achalasia which is useful for teaching and training surgical residents in advanced laparoscopic surgery. 相似文献

Pancreatic fistula is a major cause of morbidity and mortality after pancreaticoduodenectomy. External drainage of pancreaticojejunostomy anastomosis with a stent is used to reduce the rate of pancreatic fistula. This study compares the rates of pancreatic fistula between external stent drainage versus no-stent drainage for pancreaticojejunal anastomosis following pancreaticoduodenectomy. A total of 53 patients undergoing pancreaticoduodenectomy for various benign and malignant pathologies were included in the study. An external stent was inserted across the anastomosis to drain the pancreatic duct in 26 patients and 27 patients received no stent. The primary end point was pancreatic fistula. All surgeries were done by a single surgeon with expertise in hepatobiliary pancreatic surgery at a single institute. The two groups were comparable in demographic data, underlying pathologies, presenting complaints, presence of comorbid illnesses and proportion of patients with preoperative biliary drainage, pancreatic consistency and duct diameter. The pancreatic fistula rates were similar in both the groups (11.5 vs. 14.8?%, P?=?0.725). The morbidity and surgical re-exploration rate were statistically not significant between the two groups (65.4 vs. 51.9?%, P?=?0.318 and 11.5 vs. 7.4?%, P?=?0.60). Postoperative stay was also similar with a mean of 14?days in both the groups (P?=?0.66). The mortality rate was statistically not significant in the two groups (3.8 vs. 7.4?%, P?=?0.575). External drainage of pancreaticojejunostomy anastomosis and the pancreatic duct with a stent does not decrease the rate of postoperative pancreatic fistula after pancreaticoduodenectomy. 相似文献

IntroductionPediatrics is one of the medical specialties in which blood cultures for bloodstream infections are performed very frequently. This study aimed to evaluate pediatric residents’ knowledge and perceptions of blood culture sampling.Material and methodsBetween June 2019 and September 2019, a questionnaire comprising 20 questions about blood culture sampling was sent via email to participants who were pediatric residents at five different hospitals in Turkey. There were 11 true/false and nine multiple-choice questions that assessed three aspects of culture sampling: indications, sampling practice and knowledge, and contamination. The percentage of correct answers was used to calculate an overall score and subsection scores.ResultsA total of 132 pediatric residents [102 (77%) female] with a mean age of 28.3 ± 2.8 years completed the questionnaire. Forty-five (35%) were in their 1st year of residency. Sixty (46%) participants reported that they had not performed blood culture sampling in the last week. There was a negative relationship between years in training and the number of cultures performed (Kendal's tau-b = ?0.297, p < 0.001). The overall median score was 65 (range, 35–90) and it seemed to increase with years of training. The lowest median score was in the contamination subscale and only one (0.76%) participant correctly answered all questions concerning contamination.ConclusionResidents who obtained the majority of blood cultures had the lowest knowledge levels. Therefore, it is evident that the knowledge levels of pediatric residents must be increased in order to improve blood culture sampling practices in centers where they perform blood culture sampling. 相似文献

Many naturally occurring volatile chemicals that are detected through the sense of smell contain unsaturated (double or triple) carbon-carbon bonds. These bonds can affect odors perceived by humans, yet in a prior study of unsaturated hydrocarbons we found only very minor effects of unsaturated bonds. In the present study, we tested the possibility that unsaturated bonds affect the recognition of oxygen-containing functional groups, because humans perceive odor differences between such molecules. We therefore compared spatial activity patterns across the entire glomerular layer of the rat olfactory bulb evoked by oxygen-containing odorants differing systematically in the presence, position, number, and stereochemistry of unsaturated bonds. We quantified activity patterns by mapping [(14)C]2-deoxyglucose uptake into anatomically standardized data matrices, which we compared statistically. We found that the presence and number of unsaturated bonds consistently affected activity patterns, with the largest effect related to the presence of a triple bond. Effects of bond saturation included a loss of activity in glomeruli strongly activated by the corresponding saturated odorants and/or the presence of activity in areas not stimulated by the corresponding saturated compounds. The position of double bonds also affected patterns of activity, but cis vs. trans configuration had no measurable impact in all five sets of stereoisomers that we studied. These results simultaneously indicate the importance of interactions between carbon-carbon bond types and functional groups in the neural coding of odorant chemical information and highlight the emerging concept that the rat olfactory system is more sensitive to certain types of chemical differences than others. 相似文献
