The cause of non-anastomotic graft aneurysms is most likely due to a basic structural failure in the graft, as a result of defects in fabrication, Dacron fibre deterioration or a combination of both. Local excision of the graft defect with interposition graft replacement is an accepted treatment for local graft failure. However, as fabrication defects and Dacron fibre deterioration are both factors affecting the whole graft, it is not surprising to find multiple aneurysms in the same graft synchronously or metachronously. Thus, a total graft replacement should be the treatment of choice for graft failure.","PeriodicalId":7943,"journal":{"name":"Annals of The College of Surgeons Hong Kong","volume":"14 1","pages":"123-125"},"PeriodicalIF":0.0,"publicationDate":"2002-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87826762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The appendix positions were divided into two groups: (i) the anterior group, which included the anterior, the pelvic and the paracaecal positions; and (ii) the posterior group, which included the retrocaecal and retroileal positions. \u0000 \u0000 \u0000 \u0000Method: The hospital records of 161 patients who underwent appendectomy for acute appendicitis from January 2000 to June 2001 at Prince of Wales Hospital were reviewed retrospectively. \u0000 \u0000 \u0000 \u0000Results: Clinicians’ delay in reaching the diagnosis was longer in the posterior group (9.9 h vs 5.8 h; P=0.043). However, complicated appendicitis (gangrenous changes, perforation or abscess formation) was not associated with the appendix location (P = 0.078). The median operating time for laparoscopic appendectomies lasted longer in the posterior group (77.5 min vs 60 min; P = 0.02). These patients also had a longer hospital stay (6 days vs 4 days; P = 0.049). No difference was observed among patients who underwent open surgery. \u0000 \u0000 \u0000 \u0000Conclusion: Appendices in the ‘hidden’ position did not translate into a higher incidence of complicated appendicitis or postoperative complications except for the slightly longer hospital stay in patients treated by laparoscopy. Therefore, we concluded that the location of appendices does not affect the clinical course of appendicitis in the locality studied.","PeriodicalId":7943,"journal":{"name":"Annals of The College of Surgeons Hong Kong","volume":"21 1","pages":"109-112"},"PeriodicalIF":0.0,"publicationDate":"2002-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88700514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two 4 cm × 4 cm full-thickness wounds were created on the dorsal surface of 10 Spraque–Dawley rats and covered with Hyphecan and Kaltostat, respectively. Wounds were examined and measured on days 4, 10, 21 and 28, and would continue after day 28 until healed up completely. Punch biopsies (3 mm) were taken on days 4, 10 and 28 for histological examination of the response of healing and repair. \u0000 \u0000 \u0000 \u0000Results: Despite the fact that the wound healing rate was similar for both groups on days 4, 10, 21 and 28, the average healing time for the Hyphecan group (29.1 ± 1.7 days) was significantly shorter statistically (P = 0.03) than the Kaltostat group (30.7 ± 2.8 days). Conversely, the marked healing response elicited by Hyphecan on day 4 persisted on days 10 and 28 in contrast to Kaltostat, which had only a mild degree of healing response on days 10 and 28. The study suggests that wounds treated by Hyphecan heal faster than Kaltostat. \u0000 \u0000 \u0000 \u0000Conclusion: The findings provide basic scientific evidence supporting the clinical use of Hyphecan in different wounds and might also reduce the cost of wound management as Hyphecan is cheaper than Kaltostat and requires a shorter treatment time.","PeriodicalId":7943,"journal":{"name":"Annals of The College of Surgeons Hong Kong","volume":"35 1","pages":"113-117"},"PeriodicalIF":0.0,"publicationDate":"2002-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77306911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, when and how the H. pylori status should be determined remains unclear. The study investigated the role of early endoscopic follow up in managing patients with simple omentopexy for duodenal ulcer perforation. \u0000 \u0000Patients and Method: \u0000Patients below the age of 75 years who had simple repair of perforated duodenal ulcer were recruited. They were given a 4-week course of H2 receptor antagonist upon discharge and advised to return for a follow-up endoscopy at 8 weeks after operation. During endoscopic examination, ulcer healing and other gastroduodenal pathology were noted. Random biopsies were taken from the antrum and body of the stomach for determination of H. pylori infection. \u0000 \u0000Results: \u0000In a 30-month period, 112 patients were admitted with perforated duodenal ulcers. The perforation was repaired by either laparoscopic (n = 41) or open method (n = 71). Eleven patients died during hospitalization. Of the 101 patients who recovered, 16 were lost to follow up. Nine patients were considered unfit for endoscopy as a result of medical comorbidities. Among the 76 patients who attended the follow-up endoscopy, 47 were shown to have H. pylori infection (61.8%). Active duodenal ulcers were found in 15 patients, significant erosions in five patients and severe duodenitis in seven patients. Patients infected by H. pylori had a significantly higher proportion of persistent duodenal pathology compared with the uninfected patients (23/47 vs 4/29; P = 0.003). Multivariate analysis revealed that smoking and H. pylori infection were the two independent factors predicting persistent duodenal lesions. \u0000 \u0000Conclusion: \u0000Patients treated with simple closure for duodenal ulcer perforation are recommended to have their H. pylori status determined by early follow-up endoscopy, and an eradication regimen should be prescribed to those who are positive for the infection. \u0000 \u0000Chinese Abstract \u0000 \u0000 \u0000 \u0000Figure Chinese Abstract. \u0000 \u0000 \u0000 \u0000Figure Chinese Abstract. \u0000 \u0000 \u0000 \u0000Figure Chinese Abstract. \u0000 \u0000 \u0000 \u0000Figure Chinese Abstract. \u0000 \u0000 \u0000 \u0000Figure Chinese Abstract.","PeriodicalId":7943,"journal":{"name":"Annals of The College of Surgeons Hong Kong","volume":"139 1","pages":"71-76"},"PeriodicalIF":0.0,"publicationDate":"2002-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76577725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
