METHODS:Primary blepharoplasty was carried out on both eyelids of 18 albino rabbits. After 2 weeks, a new skin incision was made, and adhesiolysis was performed on both eyelids. The rabbits were categorized into two groups, one with adhesiolysis alone in the left eyelid (control group), and the other with adhesiolysis with a Seprafilm graft in the right eyelid (Seprafilm group). The degrees of inflammation and fibrosis were examined with hematoxylin-eosin (HE) and Masson’s trichrome stains. Expression of α-smooth muscle actin (α-SMA) was also immunohistochemically examined. RESULTS:Eyelid examination immediately after the operation revealed mild swelling and hemorrhage in both groups, but these symptoms resolved after 1 week-2 weeks, and eyelid shape had recovered completely in both groups. Microscopic assessments demonstrated that the Seprafilm group showed less inflammation and fibrosis than the control group. The Seprafilm group also exhibited fewer α-SMA-positive cells than the control group. CONCLUSION:Based on these findings, we conclude that Seprafilm graft with adhesiolysis is an effective method for preventing postoperative readhesions after eyelid surgery.展开更多

SEP can be classified as idiopathic,also known as abdominal cocoon,or secondary. It is difficult to make a definite pre-operative diagnosis. We experienced five cases of abdominal cocoon,and the case files were reviewed retrospectively for the clinical presentation,operative findings and outcome. All the patients presented with acute,subacute and chronic intestinal obstruction. Computed tomography (CT) showed characteristic findings of small bowel loops congregated to the center of the abdomen encased by a soft-tissue density mantle in four cases. Four cases had an uneventful post-operative period,one case received second adhesiolysis due to persistent ileus. The imaging techniques may facilitate pre-operative diagnosis. Surgery is important in the management of SEP.展开更多

However, long-term surgical results have not been documented well.AIM In this paper, we report unusual patients who manifested jejunal limb stricture near the esophageal hiatus without anastomotic stenosis during long-term observation after surgery.METHODS From April 2009 until May 2020, we retrospectively reviewed 211 patients underwent LTG following by OEJ for gastric carcinoma and took a standard surveillance program. We aimed to characterize a novel complicated disorder observed in these patients to assist treatment and prevention.RESULTS Five patients(2.4%) had unusual jejunal limb stricture after LTG and OEJ,occurring at a mean of 10 mo after initial radical LTG. All five patients had disturbed oral intake and marked weight loss, and two had aspiration pneumonia.Various diagnostic modalities and intraoperative findings in each patient revealed an intact anastomosis, bent or tortuous jejunal limb resulting from loose fibrous adhesions on the left crus at the esophageal hiatus and no cancer recurrence. All five patients were successfully treated by reoperation for adhesiolysis, division of the left crus and rearrangement of the jejunal limb.CONCLUSION Disturbed passage through the jejunal limb near the hiatus can occur after some types of OEJ following LTG. We speculate that it may result from a short remnant esophagus, excessive mobilization of the jejunal limb that permits bending or tortuosity and adhesions on the left crus at the hiatus. Prevention for this complication is possible during the original LTG procedure.展开更多

Objectives...Background: Infertility is a global problem, but the highest prevalence is in low resource countries, particularly in sub-Saharan Africa where tubal damage following pelvic infection is the commonest cause. Objectives: This study aimed to assess contribution of laparoscopy as a diagnostic and therapeutic tool in infertile women in our setting. Methods: A descriptive review of complete medical records of 208 women who underwent laparoscopy at the Gynaecology Unit of Yaoundé General Hospital from December 2007 to December 2012. Results: Two hundred and eight women were enrolled in this study. Mean age was 32.6 ± 11.25 years. Infertility was secondary in 71.6% of cases;125 (60.1%) women were married and 116 (55.8%) had a positive serology of Chlamydia trachomatis infection. The most frequent findings during diagnostic laparoscopy were: pelvic adhesions (83.7%), hydrosalpinx (21.6%), pyosalpinx (4.8%), perihepatic adhesions (25.5%), uterine fibromas (22.6%), pelvic endometriosis (13%) and ovarian abnormalities (10.1%). The surgical procedures during laparoscopy were: adhesiolysis (79.7%), tuboplasty (35.0%), salpingectomy (8.2%), ovarian cystectomy (5.8%) and myomectomy (1.9%). Three (1.4%) cases of uterine perforation and 1 (0.5%) case of laparoscopy conversion to laparotomy were observed. Conclusion: Diagnostic laparoscopy revealed that tubal lesions and pelvic adhesions were still the major causes of female infertility in developing countries. Adhesiolysis and tuboplasty were the most frequently performed surgical procedures during laparoscopy. Therefore, training in endoscopic surgery should be regarded as an important issue in developing countries.展开更多
