【摘要】 目的 探讨结直肠癌致肠梗阻的诊断和治疗。方法 回顾性分析2003年1月—2008年12月间72例结直肠癌致肠梗阻的外科诊治资料。结果 72例患者中肿瘤位于右半结肠23例,左半结肠29例,直肠16例,回盲部4例。其中63例手术治疗,一期切除吻合46例,Hartmann术7例,单纯造口10例。有9例因肿瘤全身广泛转移等因素自动放弃手术治疗。结论 重视对结直肠癌致肠梗阻的认识、合理选择手术方式、做好围手术期处理是减少并发症、提高疗效的重要措施。
Fifty three patients with acute necrotizing pancreatitis were performed operation, treated surgically, including incision of the pancreatic capsule to release the pancreatic presure, removal of necrotic tissue, and placement of drainage tube around pancreas. Twenty two patients (41.5%) developed postoperative peripancreatic abscess. The average hospitalized days (83.3±25.1 days) of the patients with peripancreatic abscess was longer than those without (22.7±14.7 days) peripancreatic abscess (Ｐ＜0.01). Six cases of 28 (21.4%) patients who had localized or scattered pancreatic necrosis developed peripancreatic abscess, 16 cases of 25 (64.0%) patients who had subtotal or total pancreatic necrosis developed peripancreatic abscess which showed significant difference between two groups (Ｐ＜0.01). Among 21 patients in whom 2 to 4 doublelumened tubes for negative presure drainage were placed,5 cases (23.8%) had peripancreatic abscess but 32 patients with only one tube placed, 17 patients (53.1%) had peripancreatic abscess, the difference between two groups were significant (Ｐ＜0.05). At least 6 patients whose drainage tubes worked badly produced postoperative peripancreatic abscess. These results indicate that the peripancreatic abscess is closely related with the severity of the disease, surgical treatment, and proper postoperative care of the drainage tubes.
胆总管在穿过十二指肠壁时与胰管汇合，汇合后略膨大，称Vater壶腹（简称壶腹）。壶腹及其外周环绕的括约肌向十二指肠肠腔突出，使十二指肠粘膜隆起形成十二指肠乳头。在壶腹周围（包括壶腹），上述组织结构所发生的肿瘤统称为壶腹周围肿瘤，并以恶性居多。壶腹周围的恶性肿瘤包括来自壶腹、胆总管下端、十二指肠乳头和胰头的癌肿，临床上把前三者连同胰头癌统称为壶腹周围癌。目前，外科手术仍是治疗壶腹部肿瘤的主要手段，提高壶腹部肿瘤的外科治疗技术水平是患者获得治愈的唯一途径。壶腹部肿瘤因其组织来源不同其生物学行为亦表现出很大差异，应根据壶腹部肿瘤的不同组织来源、生物学行为及其发展阶段作出合理的外科治疗。
