Rectal stenosis after procedures for prolapse and hemorrhoids (PPH)--a report from China.
OBJECTIVES: After it was introduced in China in 2000, the surgical procedure for prolapse and hemorrhoids (PPH) has become a widely accepted for third- and fourth-degree hemorrhoids. Stenosis of the lower rectum is one of the delayed complications. In order to evaluate this specific problem following PPH, we reviewed our data with special reference to potential predictive factors or stenotic events. METHODS: A retrospective analysis of 554 consecutive patients that underwent PPH from July 2000 to December 2004 was performed. Only patients with follow-up check were evaluated; therefore 65 patients (11.7%) Hwere lost to follow-up, and the analysis therefore includes 489 patients with a mean follow-up of 324 days (+/-18 days). For statistical analysis, the groups with and without stenosis were evaluated using the chi-square test; using the Kaplan-Meier statistic, the actuarial incidence for rectal stenosis was plotted. RESULTS: Rectal stenosis was observed in 12 patients (2.5%) in whom the median time to stenosis was 125 (89 approximately 134) days. All patients complained of obstructive defecation and underwent strictureplasty with electrocautery or balloon dilation through colonoscopy. A statistical analysis revealed that two factors were significantly more prevalent among patients with stenosis: prior sclerosis therapy for hemorrhoids (P=0.02) and severe postoperative pain (P=0.003). Other factors, such as gender (P=0.32), prior surgery for hemorrhoids (P=0.11), histological evidence of squamous skin (P=0.77) or revision (P=0.53) showed no significance. CONCLUSIONS: Rectal stenosis is an uncommon event after PPH. Early stenosis will occur within the first 4 months after surgery. In most cases, the stenosis can be cured through colonoscopy surgery. Predictive factors for stenosis are previous sclerosis therapy for hemorrhoids and severe postoperative pain.
The neurophysiological significance of perineal descent.
The establishment of a linear relationship between perineal descent (PD) and pudendal nerve motor terminal latency (PNMTL) is important in understanding the pathophysiology of pudendal neuropathy. The amount of stretching of the pudendal nerve resulting from the extent of PD, should correlate with the amount of injury sustained (PNMTL). The two key previous studies which used different techniques to measure PD, have differed on this vital issue. A prospective study was undertaken in 141 consecutive patients with PD (M:F = 57:84; mean age 46.3 SEM 1.6 years) to clarify this discrepancy. The patients had chronic constipation (81), neurogenic faecal incontinence (31), rectal mucosal prolapse (17) or female urinary stress incontinence (9). All underwent measurements of PD (by perineometry), anal sphincter pressures, single fibre anal sphincter electromyography and PNMTL. These variables, as well as age were analyzed for a linear relationship with PD by multiple regression analysis. Age was the only independent variable predicting PD at rest (T = -3.2; p < 0.005). PNMTL was the only independent variable predicting PD on straining (T = -3.0; p < 0.005). In conclusion, a linear relationship between PD on straining and PNMTL was confirmed, supporting the previous study which also measured PD by perineometry. The other study which refuted such a relationship measured PD radiologically, and it is likely that the difference was in the measurement technique.

Bleeding, incontinence, pain and constipation after STARR transanal double stapling rectotomy for obstructed defecation.
BACKGROUND: The STARR double stapling procedure (DSP), i. e. transanal anteroposterior rectotomy, has been recently reported as a low-morbidity and effective operation for the treatment of rectocele and internal rectal mucosal prolapse (R-IMP) causing obstructed defecation. We report the postoperative complications and recurrence of symptoms following this novel operation. PATIENTS AND METHODS: Fourteen chronically constipated women with RIMP, aged 36-72 years, presented with either severe complications or recurrence of symptoms following DSP performed by means of two circular staplers. All were followed for a median period of 12 months (range, 2-24) after DPS. RESULTS: Severe rectal bleeding occurred in two cases postoperatively. Persistent severe anal pain was reported by seven patients, all presenting with anxiety. Four of them were multiparous. Three patients had fecal incontinence, both had vaginal deliveries. R-IMP recurred in six, obstructed defecation in seven cases. Four patients needed reintervention, one for suturing the bleeding area, one excising the recurrent prolapse, one for colpocele and one for rectal stricture. Four patients required biofeedback training for non-relaxing puborectalis and two needed psychotherapy. CONCLUSION: Parity, spastic floor syndrome and psychoneurosis seem to be the risk factors predisposing to failure of DSP, which may be followed by severe complications and early recurrence of symptoms requiring reoperation.

Long-term results of endoscopic hemorrhoidal ligation: two different devices with similar results.
BACKGROUND AND STUDY AIMS: To evaluate the efficacy of two different endoscopic hemorrhoidal ligation (EHL) devices for symptomatic internal hemorrhoid. PATIENTS AND METHODS: From November 2000 to February 2001, 218 consecutive patients with symptomatic internal hemorrhoids were enrolled. A total of 109 patients were treated with an EHL device 9 mm in diameter (group A); the rest were treated with a device 13 mm in diameter (group B). The patients' clinical presentations were rectal bleeding and prolapse. The severity of the hemorrhoid was classified using Goligher's grading. RESULTS: All patients were treated for one session, and were followed from 19 to 24 months (mean 22.4 months). The number of band ligations averaged 2.59 in group A and 1.68 in group B. Most patients had their hemorrhoids reduced by at least one grade (82.8 % in group A and 90.8 % in group B). Rectal bleeding was controlled in 108 patients (99.1 %) in group A and 109 patients (100 %) in group B, while rectal prolapse was reduced in 93 patients (85.3 %) in group A and 99 patients (90.8 %) in group B. Eleven patients in group A and 12 in group B experienced anal pain after treatment, and eight patients in group A and six in group B had mild bleeding. The patients' subjective satisfaction rates were 90.8 % in group A and 93.6 % in group B. The 1-year recurrence rates were 3.9 % in group A and 2.3 % in group B. CONCLUSIONS: Both EHL devices can effectively treat symptomatic internal hemorrhoids. A device with a smaller diameter requires more band ligations, but appears equivalent with regard to treatment outcome and complications.
