Clinical outcomes of surgical management for recurrent rectal prolapse: a multicenter retrospective study

Purpose@#There are few reports on outcomes following surgical repair of recurrent rectal prolapse. The purpose of this study was to examine surgical outcomes for recurrent rectal prolapse. @*Methods@#We conducted a multicenter retrospective study of patients who underwent surgery for recurrent rectal prolapse. This study used data collected by the Korean Anorectal Physiology and Pelvic Floor Disorder Study Group. @*Results@#A total of 166 patients who underwent surgery for recurrent rectal prolapse were registered retrospectively between 2011 and 2016 in 8 referral hospitals. Among them, 153 patients were finally enrolled, excluding 13 patients who were not followed up postoperatively. Median follow-up duration was 40 months (range, 0.2–129.3 months). Methods of surgical repair for recurrent rectal prolapse included perineal approach (n = 96) and abdominal approach (n = 57). Postoperative complications occurred in 16 patients (10.5%). There was no significant difference in complication rate between perineal and abdominal approach groups. While patients who underwent the perineal approach were older and more fragile, patients who underwent the abdominal approach had longer operation time and admission days (P < 0.05). Overall, 29 patients (19.0%) showed re-recurrence after surgery. Among variables, none affected the re-recurrence. @*Conclusion@#For the recurrent rectal prolapse, the perineal approach is used for the old and fragile patients. The postoperative complications and re-recurrence rate between perineal and abdominal approach were not different significantly. No factor including surgical method affected re-recurrence for recurrent rectal prolapse.

Minimal Lateral Internal Sphincterotomy (LIS): Is It Enough to Cut Less Than the Conventional Tailored LIS?

Purpose@#Anal fissure is a common anorectal condition, yet its pathogenesis remains unclear. Lateral internal sphincterotomy (LIS) is the gold standard treatment for chronic anal fissures that do not respond to conservative treatment; however, it has a risk of anal incontinence. We believe that fibrosis of the internal anal sphincter is an important factor in the pathogenesis of chronic anal fissure. In this study, we describe the minimal LIS method, a minimally invasive method where only the fibrotic portion of the internal anal sphincter is cut. We also describe the outcomes of this method. @*Methods@#We performed a retrospective review of 468 patients (270 male and 198 female) who underwent minimal LIS for chronic anal fissure in 2017 at Seoul Song Do Hospital. We analyzed the patients’ clinical characteristics, manometry data, complications, and outcomes of minimal LIS. The outcomes of the surgery were assessed via questionnaires during the postoperative outpatient visits, beginning 2 weeks postoperatively. @*Results@#The overall complication rate was 4.0% (19 patients). Delayed healing occurred in 14 patients (3.0%), perianal abscess was present in 3 patients (0.6%), and gas incontinence occurred in 2 patients (0.4%). All complications were improved with conservative treatment. Recurrence, defined as the recurrence of anal fissure more than 4 weeks after healing, was present in 6 patients (1.3%). @*Conclusion@#Minimal LIS is a safe and effective treatment option for patients with chronic anal fissure. Postoperative complications, especially incontinence and recurrence, are rare.

Comparison of Delorme-Thiersch Operation Outcomes in Men and Women With Rectal Prolapse

PURPOSE: The laparoscopic rectopexy has become increasingly popular with verified stability, surgical route selection should be tailored to individual patient characteristics rather than operative risk. The perineal approach is useful in young male patients who need to preserve fertility. This study aimed to compare the characteristics of men and women who underwent Delorme-Thiersch procedures and analyze the postoperative outcomes of the perineal approach by sex. METHODS: We retrospectively reviewed the medical records of 293 patients who underwent Delorme-Thiersch operations in Seoul Song Do Colorectal Hospital between January 2011 and September 2017. Patient clinical characteristics and postoperative complications were analyzed by sex. We analyzed surgical outcomes with preoperative and 3-month postoperative incontinence questionnaires, constipation levels, and anal manometry. RESULTS: In this study, men with rectal prolapse were younger than women with the same condition. American Society of Anesthesiologists physical status classifications were higher in women and women had more L-spine X-ray and pudendal nerve terminal motor latency test abnormalities. Anorectal manometry pressures were higher in men. Men also had longer operation times and hospital stays and more postoperative complications (8 T ring infections, 6 patients with bleeding, 3 with strictures, 2 with severe pain, and 2 with rectal perforations). The recurrence rate was higher among women. CONCLUSION: Men with rectal prolapse were younger, healthier, and had relatively better anorectal function than women. The Delorme-Thiersch operation in men promoted lower recurrence rates and was advantageous in preserving the fertility of young patients, but the incidence of complications was also higher in men. Adequate counseling and preparation for the possibility of complications are needed.

Laparoscopic Posterolateral Rectopexy for the Treatment of Patients With a Full Thickness Rectal Prolapse: Experience With 63 Patients and Short-term Outcomes

PURPOSE: Although numerous procedures have been proposed for the treatment of patients with a rectal prolapse, the most effective operation has not yet been established. Minimal rectal mobilization can prevent constipation; however, it is associated with increased recurrence rates. We describe our novel method for a laparoscopic posterolateral rectopexy, which includes rectal mobilization with a posterior-right unilateral dissection, suture fixation to the sacral promontory with a polypropylene mesh (Optilene), and a mesorectal fascia propria that is as wide as possible. The present report describes our novel method and assesses the short-term outcomes of patients. METHODS: Between June 2014 and June 2017, 63 patients (28 males and 35 females) with a full-thickness rectal prolapse underwent a laparoscopic posterolateral (LPL) rectopexy. We retrospectively analyzed the clinical characteristics and postoperative complications in those patients. The outcome of surgery was determined by evaluating the answers on fecal incontinence questionnaires, the results of anal manometry preoperatively and 3 months postoperatively, the patients’ satisfaction scores (0–10), and the occurrence of constipation. RESULTS: No recurrence was reported during follow-up (3.26 months), and 3 patients reported postoperative complications (wound infection, postoperative sepsis, which was successfully treated with conservative management, and retrograde ejaculation). Compared to the preoperative baseline, fecal incontinence at three months postoperatively showed an overall improvement. The mean patient satisfaction score was 9.55 ± 0.10, and 8 patients complained of persistent constipation. CONCLUSION: LPL rectopexy is a safe, effective method showing good functional outcomes by providing firm, solid fixation for patients with a full-thickness rectal prolapse.

High Expression of Urokinase-Type Plasminogen Activator Is Associated with Lymph Node Metastasis of Invasive Ductal Carcinoma of the Breast / 한국유방암학회지

PURPOSE: In the present study, we evaluated the levels of urokinase-type plasminogen activator (uPA) and plasminogen activator inhibitor 1 (PAI-1) by performing immunohistochemical staining to determine whether they were reliable prognostic markers in patients with breast cancer. METHODS: Demographic and clinicopathological parameters of 214 patients with invasive ductal carcinoma (IDC) and 80 patients with ductal carcinoma in situ (DCIS) who were diagnosed and treated from 2006 to 2010 were analyzed. Tissue microarray was constructed and immunohistochemical staining was performed for each specimen. RESULTS: Univariate analyses showed that age at diagnosis, history of hormone replacement therapy, radiation therapy, skin and chest wall invasion, Paget disease, lymphovascular invasion, estrogen receptor positivity, and triple-negative subtype were significantly associated with patient prognosis (p<0.005). Patients with DCIS showed higher PAI-1 expression than patients with IDC (82.5% and 36.2%, respectively; p=0.012). Lymph node metastasis was more frequent in patients with high uPA levels than in patients with low uPA levels (p=0.001). CONCLUSION: Our results suggested that PAI-1 was involved in tumor progression in the early stages of breast cancer, such as DCIS. In addition, our results suggested that high uPA levels were associated with the lymph node metastasis of IDC.
