目的:探讨肛肠疾病手术前后肛管直肠压力测定的应用。方法:将2018年5月-2019年5月在上海市松江区方塔中医医院及上海中医药大学附属曙光医院肛肠科行手术治疗的826例肛肠疾病患者作为研究对象,其中,选择性痔上黏膜吻合术246例、单纯外剥内扎术115例、外剥内扎结合内痔套扎术(Automatic Ligation of Hemorrhoids,RPH)153例、低位肛瘘切除术177例、高位肛瘘切开挂线术135例,分别于术前及术后1个月测定肛管直肠压力。结果:选择性痔上黏膜吻合术后直肠静息压、肛管静息压明显低于术前,肛管舒张压高于术前(P<0.05),但肛管最大收缩压与术前相比无明显差异(P>0.05);单纯外剥内扎术术后直肠静息压、肛管静息压明显低于术前,肛管舒张压、肛管最大收缩压明显高于术前(P<0.05);外剥内扎结合内痔套扎术术后直肠静息压、肛管静息压明显低于术前,肛管舒张压、肛管最大收缩压明显高于术前(P<0.05);低位肛瘘切除术术后直肠静息压、肛管静息压、肛管舒张压均高于术前(P<0.05),而肛管最大收缩压与术前相比无明显差异(P>0.05);高位肛瘘切开挂线术术后直肠静息压高于术前,肛管静息压、肛管舒张压低于术前(P<0.05),而与肛管最大收缩压术前相比无明显差异(P>0.05)。结论:肛肠疾病手术前后肛管直肠压力测定的应用效果显著,能准确判断手术效果及患者恢复情况,为医师的进一步诊治奠定了良好基础。     

Anorectal function in the solitary rectal ulcer syndrome

The anorectal function of nine patients with solitary rectal ulcer syndrome (SRUS) (5 F: 4 M, median age, 27 (range, 19–41 years) and nine control subjects (5 F: 4 M, median age, 47 (35–66)P<0.01) has been investigated by a new technique that radiologically visualizes the anorectum during voiding of a semisolid contrast medium, while simultaneously measuring intrarectal pressure and anal sphincter EMG activity. A degree of rectal prolapse was demonstrated in eight of the SRUS patients; six of these lesions were clinically occult. Abnormal failure of the anal sphincter to relax on voiding was present in seven of the SRUS patients. These abnormalities resulted in the SRUS patients requiring a greater increase in intrarectal pressure (median, 100 cm water) to void than the control subjects (median, 65 cm water,P<0.01). This combination of high intrarectal pressure and rectal prolapse during straining seems to be the cause of SRUS This work was supported by a grant from the Medical Research Council.     

Total anorectal reconstruction with a double dynamic graciloplasty after abdominoperineal reconstruction for low rectal cancer

PURPOSE: Total anorectal reconstruction with a double dynamic graciloplasty was performed after abdominoperineal reconstruction (APR) for low rectal cancer. In four patients an additional pouch was constructed to improve neorectal motility and capacity. The aim of this study was to evaluate the results in the first 20 patients and to report on the preliminary results of patients with an additional pouch. METHODS: Twenty patients with a mean age of 52 (range, 25–71) years and a rectal tumor at a mean of 3 (range, 0–5) cm from the anal verge were treated. In 14 patients the Miles resection, colon pull-through, and construction of a neosphincter were performed in one session. Six patients had the double graciloplasty at an average of 4.1 (range, 1.1–8.8) years after APR. In four patients a pouch was constructed with an isolated segment of distal ileum. RESULTS: After a mean follow-up of 24 (range, 1–60) months after APR, none of the patients developed local recurrence, whereas four patients developed distant metastasis. Fifteen of 20 patients were available for evaluation, and 5 patients were still in training. Of these 15 patients, 8 patients were continent (53 percent), 2 patients were incontinent, and in 5 patients the perineal stoma was converted to an abdominal stoma. Failures were attributable to necrosis of the colon stump (n=2) and incontinence (n=3). At 26 weeks mean resting pressure was 44 (standard deviation (SD), 28) mmHg, and mean pressure during stimulation was 90 (SD, 46) mmHg at a mean of 35 (SD, 1.2) volts at 52 weeks. Mean defecation frequency was three times per day (range, 1–5). Of the eight patients who were continent, six used daily enemas. Mean time to postpone defecation was 11 (range, 0–30) minutes. CONCLUSION: In experienced hands, the double dynamic graciloplasty is an oncologically safe procedure that can have an acceptable functional outcome in a well-selected group of patients. However, to improve the outcome, further modifications will be necessary. So far, the addition of a pouch has not resulted in improved outcome.

Clinical and manometric evaluation of anorectal function following low anterior resection with low anastomotic line using an EEA™ stapler for rectal cancer

Anorectal function was evaluated in eight patients who had low anterior resection of the rectum with a low anastomotic line, using an EEA^™ stapler, with determination of function based on periodic manometric studies and clinical symptoms. Immediately following surgery all patients suffered from frequent bowel actions and soiling. These symptoms improved with time and most patients could enjoy almost normal daily life by the sixth postoperative month. One month after surgery, anal canal resting pressure and maximum squeeze pressure were significantly reduced and rectoanal inhibitory reflex was absent; neither showed a distinct tendency to improve thereafter. Rectal sensation and reservoir capacity, which also were seriously impaired, recovered satisfactorily by the time of the six-month examination. This suggests that an improvement of clinical symptoms following this operation is dependent upon the recovery of reservoir capacity and sensation of the neorectum, and that this operative procedure is a functionally acceptable option for low rectal cancer.     

Primary anastomosis for complete bulbar urethral rupture with rectal laceration caused by straddle injury: A case report

IntroductionThe initial management of urethral trauma remains disputed, and there are several suitable techniques, including delayed repair and suprapubic urinary diversion as well as primary endoscopic or open alignments. The treatment choice used depends on the rupture’s location and length as well as the accompanying trauma.Case presentationA 33-year-old male patient was referred to the department of emergency, with the chief complaint of inability to void experienced 1 day before being admitted, after falling from a height of approximately three meters. There was a laceration to the perineum 3 cm long to the rectum, with no active bleeding. After the incident, the patient could not void, but the lower abdomen was not painful. Upon retrograde urethrography examination, contrast extravasation of the bulbous urethra was seen through the anorectal laceration. Immediate debridement and repair for the anorectal wound, then primary anastomosis for the bulbous urethra, was performed.DiscussionThe likelihood of an injury to the anterior urethra increases with certain clinical features, including blood in the urethral meatus, palpable bladder distention, and a butterfly appearance on the perineum. Immediate exploration and reconstruction of the urethra is recommended in urethral traumas associated with penile fractures and non-life-threatening penetrating injuries. Furthermore, small lacerations are repaired primarily, while total ruptures are treated with anastomosis.ConclusionProper identification and management of urethral rupture determines the outcome. Initial urethral trauma management is disputed; however, a bulbous urethra rupture with anorectal lacerations can be treated safely and effectively with primary anastomosis.     

Vaginal reconstruction using ileum segment and posterior sagittal anorectoplasty in a patient with Mayer–Rokitansky–Küster–Hauser syndrome with anorectal malformations: A case report

Vaginal agenesis with anorectal malformations is a complex pediatric condition that adversely affects various physiological processes in the body. It may cause disturbances in defecation and urination, abnormalities in the urinary and gastrointestinal tract, dysfunction of the genital and reproductive organs, and sexual function disorders. The complexity in the surgical management of vaginal agenesis includes the selection of a functional reconstruction technique for anal and vaginal formation, timing of the reconstruction, and management of complications in the associated organ system.Herein, we describe a patient with Mayer–Rokitansky–Küster–Hauser syndrome accompanied by a rectovesical fistula. Other abnormalities, such as microcephaly, polydactyly, long urethral abnormalities resembling the male urethra, and complications in the kidney and urinary tract, were observed in the patient. The associated complications included recurrent urinary tract infections, urinary overflow incontinence, vesicoureteric reflux, hydroureter, and left renal hydronephrosis. The patient underwent posterior sagittal anorectoplasty surgery and vaginal reconstruction. The long-term vaginal physiological development of patients with this condition remains unknown.
