Spigelian hernias: a prospective analysis of baseline parameters and surgical outcome of 34 consecutive patients

Most of the papers published on spigelian hernia are either case reports or small retrospective series. In this prospective multicenter study, we aimed to outline the specific features of spigelian hernias and patients’ characteristics more clearly. Surgeons enrolled patients to be entered into the database as they diagnosed and treated the hernias at will. The baseline and surgical outcome parameters were noted in each patient. A painful mass was the main presenting complaint in half of 34 patients. Accurate preoperative diagnosis was possible in 31 patients. Open intraperitoneal mesh repair was the preferred technique. The mean hospital stay and time until return to normal daily activities were 4.1 and 15.6 days. Although a rare condition, diagnosis of a spigelian hernia is not difficult once remembered. Its surgical repair seems to cause few complications and is very well tolerated by the patient.     

奥沙利铂持续腹腔热灌注治疗癌性腹水的临床研究

目的研究奥沙利铂(L-OHP)持续腹腔热灌注治疗癌性腹水的疗效和毒副作用。方法将76例癌性腹水患者随机分为三组:奥沙利铂持续腹腔热灌注化疗组(热化组)26例,引出腹水后,在加热的5%葡萄糖溶液2500～3500ml中加入L-OHP200mg/m2,持续体外循环腹腔热灌注,腹腔内温度保持在41～43℃,持续60min;腹腔内注射奥沙利铂化疗组(单化组)26例,常规腹腔穿刺引流腹水后注射L-OHP200mg/m2。单纯腹腔热灌注组(单热组)24例,加热5%葡萄糖溶液2500～3500ml,持续热灌注60min。结果总有效率(CR PR)54%(41/76)。热化组、单化组和单热组的有效率分别为76.9%(20/26)、50.0%(13/26)、33.3%(8/24),P<0.05。急性腹痛:热化组53.8%(14/26),单热组16.7%(4/24)。单化组无急性腹痛病例,P<0.05。麻痹性肠梗阻:热化组19.2%(5/26),单化组7.7%(2/26),单热组16.7%(4/24),P>0.05。结论奥沙利铂持续腹腔热灌注治疗恶性腹水是一种新的有效的治疗方法,毒副作用不大。     

顺铂腹腔注入治疗卵巢癌腹水的临床观察

晚期卵巢癌腹水的治疗相当困难,目前虽有一些治疗卵巢癌腹水的方法,但用顺铂腹腔内注入治疗卵巢癌腹水尚未见报道。我们在术前和术中用顺铂(各100mg)腹腔注入治疗20例晚期卵巢癌腹水患者。所有患者的全身状况在术前均得到明显改善,19例上皮性卵巢癌腹水患者一年内无腹水生长。该方法简单、安全,控制腹水生长效果明显,副作用少。     

Immediate changes in subcellular structures of transplanted tumors following photodynamic and laser hyperthermic therapy

Background and Objective: To further understand the precise process of the tumor cell degeneration after photodynamic therapy (PDT), laser hyperthermic therapy (LH), and combined treatments using an Nd:YAG laser. It is important to examine initial morphological alteration of tumor cells after these treatments. Study Design/Materials and Methods: In this study, nude mice bearing HeLa cell tumors were treated with PDT, LH, and combined treatments of the two. Tumor tissues obtained immediately after these treatments were analyzed using electron microscopy and morphometry. Results: In the combined treatments, which produced more severe effects on tumor cells, morphological features of apoptosis such as cytoplasmic condensation, blebs, and apoptotic bodies appeared in the cells, although the typical alteration in the nuclear chromatin was not seen. Conclusion: Cytoplasmic alterations may proceed more rapidly than nuclear alterations in the cellular degeneration induced by the single or combined treatments of PDT and LH.     

胆囊切除术引流与不引流200例临床分析

胆囊切除术后是否行腹腔引流，外科医生意见不一．本文通过对２００例胆囊切除术的对比分析，总结了“引流”与“不引流”的利弊和经验。认为择期单纯胆囊切除不必常规放置引流，但对手术后有可能发生出血、胆漏的病例，在放与不放引流犹豫不决时，仍以放置引流为妥．本文同时提出了胆囊切除术引流与不引流的适应症．     

Use of acute peritoneal dialysis catheters for intraperitoneal chemotherapy instead of the semipermanent/permanent Tenkhoff catheters

Intraperitoneal chemotherapy was administered to 13 patients with peritoneal carcinomatosis, using acute peritoneal dialysis catheters immediately before the administration of the chemotherapy. A total of 59 cycles were administered, with insertion of the corresponding catheter. There were no inflow or outflow problems and no insertion-related complications. With the removal of the catheter after its use, there is no risk of abdominal infections.     

Use of an Implantable Catheter System for Intraperitoneal Chemotherapy in Ovarian Cancer

Abstract: To check the efficiency of intraperitoneal chemotherapy of ovarian carcinomas, 15 patients were treated with instillations of mitoxantrone or cisplatinum. An implantable catheter system was used to access the abdominal cavity. Local therapy proved to be without any effect when large tumor masses were treated. Patients with small tumor residues after surgery did not benefit either, partly because of extraperitoneal progress of the disease. Patients without evidence of disease proved to be stable. Side effects of the therapy were usually mild compared with those of systemic chemotherapy. Access to the peritoneal cavity with the implantable catheter proved to be safe and reliable.     

Vagal mediation of the cholecystokinin satiety effect in rats

Central (intracerebroventricular) and peripheral (intraperitoneal) injections of the octapeptide of cholecystokinin (CCK-8) were compared to determine the most effective route of administration to elicit satiety for food intake in the rat. Subdiaphragmatic bilateral vagotomy and spinal cordotomy (T2-T3) were also performed to investigate the importance of visceral nerves for the satiety effect. CCK-8 suppressed feeding and elicited satiety resting behavior when injected peripherally but it was less effective when injected centrally. The satiety effect of CCK-8 or CCK-33 following peripheral injections was blocked by vagotomy whereas spinal cordotomy had no effect. The results indicate that some component of the vagus is required to mediate the peripherally induced cholecystokinin satiety effect, but the splanchnic nerves are not necessary. The weak effect of CCK-8 following ventricular administration is additional evidence suggesting that cholecystokinin of intestinal origin acts in the periphery rather than directly on the brain to elicit its typically rapid satiety effect in rats.     

Mobile caecum as a content in recurrent incisional hernia an incidental finding: A rare case report

IntroductionRecurrence in ventral hernia after laparoscopic repair is less as compared to conventional approach. Mobile caecum as a content of ventral hernia is a very rare entity. Standard treatment for mobile cecum is caecopexy using lateral peritoneal flap.Case reportA 40-year-old obese female, homemaker by occupation with a history of incisional hernia 2 year back and treated with intraperitoneal on lay mesh repair presented with swelling in the left lower abdomen for past 6 months. Radiological investigations revealed defect in left lower anterior abdominal wall with protruding bowel loops. Urgent exploratory Laparotomy revealed mobile segment of ileocecal junction in the hernial sac cavity. Caecopexy for the mobile caecum was done.DiscussionMobile caecum is due to embryological failure of fusion of right colonic mesentery with lateral peritoneal wall. Pre-operative diagnosis of mobile caecum is difficult to establish unless it presents as caecal volvulus Caecopexy using the lateral peritoneal flap is the standard of care.ConclusionMobile caecum can surprise the attending surgeon as a content of ventral hernia. Caecopexy using lateral peritoneal flap is the treatment of choice in all with a mobile caecum.
