目的 探讨在局部麻醉下行痔上黏膜环形切除钉合术（procedure for prolapse and hemorrhoids，PPH）治疗重度内痔的可行性及临床应用价值。方法 笔者所在医院科室从2005年起对32例Ⅲ度及Ⅳ度脱垂性内痔（含1例混合痔）患者均采用苯巴比妥＋氢溴酸东莨菪碱＋利多卡因肛管直肠环形局部浸润麻醉行PPH术，对其麻醉效果、手术时间、术中及术后疼痛、尿潴留、术后感染、肛门狭窄、住院时间、治疗满意度等进行分析。结果 32例患者均顺利完成手术，有1例术中改行低位连续硬膜外麻醉，1例辅加镇静剂及镇痛剂。术后28例对疼痛能耐受，4例需镇痛药物；1例患者有肛门坠胀感；所有患者伤口均一期愈合，无尿潴留、术后感染、出血、肛门狭窄等并发症发生；31例对疗效满意，有1例感肛门坠胀，行温水坐浴及痔疮膏纳肛治疗1周后缓解。住院时间3～6d，平均4d。32例患者均进行有效随访，随访时间2～4个月，平均3个月，无大便失禁或复发，肛门控便能力均可。结论 局部麻醉下行PPH术治疗重度内痔是一种安全可行的手术方法，麻醉操作护理简单，疗效确切，术后并发症少，术后恢复快，并可减少医疗费用。
Objective To study the effect of laparoscopic total mesorectal excision and per anum rectal pull-type of anastomosis on male patients with low rectal cancer. Methods The successful experiences of anus saving operation on 23 male patients with low rectal cancer were summarized. Results A laparoscopic total mesorectal excision technique was used, with the full separation of the rectum at the bottom. After pulling out the distal rectum together with the cancer from the anus, the transection of the proximal tumor was performed. The end-to-end anastomosis of rectum and descending colon was performed by tubular stapler. Anus was reserved successfully in the 23 cases. There was no left-tumor stump after surgery detected by postoperative pathological examinations, no anastomotic leakage, and no operative death. Conclusions To the relatively narrow male pelvis, laparoscopic total mesorectal excision and per anum rectal pull-through resection and anastomosis is safe and reliable for anus saving in low rectal cancer. It can simplify the operation, and raise the success rate of sphincter preserving in surgery of low rectal cancer.
目的 探讨应用国产吻合器行直肠癌前切除双吻合器吻合术的可行性。方法 对38例直肠癌患者行前切除时，应用国产直线及管状吻合器行双吻合器吻合。结果 术后发生吻合口漏2例(5.3%)，1例可能与术后早期腹腔化疗有关，另1例形成直肠阴道瘘。全组无吻合口狭窄。结论 国产吻合器在使用上虽不如进口一次性吻合器方便，但如果操作得当，技术熟练，仍可获类似效果，其费用仅为进口吻合器的1/30。新的改进型中国产品应用更方便，更易使此技术推广。
ObjectiveTo evaluate the application of modified perineal stapled prolapse resection in treatment of external rectal prolapse, and to assess the preliminary efficacy. MethodsClinical data of 11 patients with external rectal prolapse underwent modified perineal stapled prolapse resection in The First Affiliated Hospital of Guangzhou University of Chinese Medicine between December 2013 and August 2015 were collected for retrospectively analysis. ResultsAll patients with external rectal prolapse were performed modified perineal stapled prolapse resection with general anesthesia and (or) epidural anesthesia. The average operation time was (53.6±6.1) min (40-85 min) and the average blood loss was (35.3±10.1) mL (20-60 mL). The time of the first flatus was less than 24 h after operation, the time of the first defecation was (44.6±3.3) h (40-52 h) after operation. The average hospital stay was (9.7±1.8) d (7-12 d) and average cost was (34 635.8±1 268.8) RMB (31 796-36 212 RMB). None of them occurred serious complications such as uncontrollable anastomotic stoma bleeding, anastomotic leakage, pelvic abscess, bowel obstruction, and anastomotic straitness. All of the 11 patients were followed up for (4.7±0.8) months (3-7 months), and all patients did not suffered from recurrence and fecal incontinence during follow-up period. ConclusionsThe essential procedure for modified perineal stapled prolapse resection is cutting the prolapse open at 3 and 9 clock directly at the same time by linear staplers, and dissecting mesorectum before using the contour satpler. Modified perineal stapled prolapse resection is a safe and effective operation technique for the external rectal prolapse.
ObjectiveTo observe the effect of procedure for prolapse and hemorrhoids (PPH) combined with partial internal anal sphincterotomy (Abbreviated as combined therapy) in the treatment of severe mixed hemorrhoids complicated with high rectal and anal canal resting pressure.MethodsFrom January 2016 to June 2018, the patients with grade Ⅲ–Ⅳ mixed hemorrhoids who underwent surgical treatment in this hospital were selected for the prospective study, including 100 patients with high pressure (>70 mm Hg, 1 mm Hg=0.133 kPa) and 100 patients with low pressure (≤70 mm Hg), then which were divided into an experimental group and a control group according to the random number table method (with 50 cases in each group). The patients in the control group underwent the PPH and in the experimental group underwent the combined therapy. The therapeutic effect and perioperative indicators were observed in each group, Visual Analogue Scale (VAS) was used to evaluate the degree of pain before and after the operation, the incidence of complications and the recurrence rate of symptoms were observed, the factors influencing the therapeutic effect of combined therapy were analyzed.ResultsWhether for the patients with high or low rectal and anal canal resting pressure, although the operation time of the experimental group was significantly longer than that of the control group (t=8.996, P<0.001; t=8.927, P<0.001), the total effective rate was higher (χ2=7.294, P=0.007; χ2=6.775, P=0.009), the length of stay in hospital was shorter (t=11.922, P<0.001; t=11.442, P<0.001), the hospital expenses decreased significantly (t=2.226, P=0.028; t=2.562, P=0.012), the VAS score at 24 h and 72 h after operation were lower (24 h: t=12.659, P<0.001; t=12.191, P<0.001; 72 h: t=9.920, P<0.001; t=9.901, P<0.001), the incidence of postoperative complications was lower (χ2=7.484, P=0.006; χ2=11.416, P=0.001) in the experimental group as compared with the control group; there was no significant difference between the two groups (χ2=1.042, P=0.307; χ2=0.211, P=0.646). The course of disease and the grade of internal hemorrhoids were the independent factors influencing the marked efficiency of combined therapy (χ2=7.417, P=0.009; χ2=4.286, P=0.017).ConclusionsCombined therapy is effective in treatment of severe mixed hemorrhoids complicated with high rectal and anal canal resting pressure, it could accelerate recovery of patients and relieve pain. It should be paid attention to patients with long course of disease and severe degree of internal hemorrhoids.
