Application of Ligasure vessel sealing system in haemorrhoidectomy / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the clinical value of Ligasure vessel sealing system (LVSS) in haemorrhoidectomy.</p><p><b>METHODS</b>From December 2002 to November 2003, clinical data of 36 cases undergoing haemorrhoidectomy with LVSS were compared with those of 30 cases undergoing traditional operation,considering visual analogue scale(VAS), hospital time,operation time,hospital expenses,postoperative complication.</p><p><b>RESULTS</b>There were no significant differences in hospital expenses,postoperative complications between the two groups,but the postoperative pain scores of Ligasure haemorrhoidectomy was better than that of traditional operation. The hospital stay and operation time of Ligasure haemorrhoidectomy were shorter than those of the traditional operation.</p><p><b>CONCLUSION</b>Ligasure vessel sealing system has more advantages such as less pain, safety, facility to perform, and a shorter operation time.</p>

Effect of diode laser coagulation treatment on grade III internal hemorrhoids / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To evaluate the curative effects of diode laser coagulation on grade III internal hemorrhoids.</p><p><b>METHODS</b>From March 2004 to December 2004, 86 patients with grade III internal hemorrhoids were divided into two groups, received laser coagulation (laser group, n=46) or received hemorrhoidectomy (control group, n=40). Complications, symptom relief, pain scores and satisfaction scores were compared between the two groups six months after operation.</p><p><b>RESULTS</b>Pain scores were lower in laser group than that of the control group on the first day and seventh day after operation. Small amount of bleeding occurred in the laser group (12 cases) and control group (35 cases), however, non of them required special hemostasis. Laser coagulation and closed hemorrhoidectomy were equally effective in controlling symptomatic prolapse. There was no difference in terms of continence scores and patients satisfaction between the two groups (P> 0.05).</p><p><b>CONCLUSIONS</b>Diode laser coagulation can be considered as a safe and effective procedure for the treatment of grade III hemorrhoids.</p>

Diagnosis and treatment of mesenteric venous thrombosis early after operation / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To analyze the clinical characteristics diagnosis and treatment of patients with mesenteric venous thrombosis early after operation.</p><p><b>METHODS</b>A retrospective study was performed on the clinical data of 7 patients with mesenteric venous thrombosis early after operation from 1990 to 2004.</p><p><b>RESULTS</b>Patients had main clinical manifestations of severe abdominal pain and vomiting, but abdominal signs were slight. The systemic toxic symptoms occurred in 2 cases at late course. The examination of abdominal X- ray showed intestinal obstruction of all patients. Four patients received abdominal CT- scanning, of whom 3 patients were diagnosed as mesenteric venous thrombosis. Seven patients received exploratory operation. The necrotic intestinal segments were resected. Two patients had short intestinal syndromes after operation, one of them died of serious malnutrition. Four patients who had recurrence of portal, mesenteric and iliac venous thrombosis needed a long-term therapy of warfarin and aspirin after discharge.</p><p><b>CONCLUSION</b>It is easy to make a mistake in diagnosis because of the lacking of characteristic clinical manifestations. Exploratory operation immediately plus anticoagulant therapy is strongly recommended.</p>
