ABSTRACT: Due to the current increased longevity in the elderly population and the increased size of that population, major abdominal intervention is more frequently performed among octogenarians. This study aimed to compare the surgical and postoperative outcomes of laparoscopic colorectal resections with those of open surgery in the octogenarian population.
Retrospective analysis based on a prospectively maintained database of octogenarians who underwent laparoscopic or open elective colorectal resections from 2001 to 2008 was performed. Diagnosis, comorbidities, operative data, and early postoperative complications are analyzed in this report.
Colon resection was performed for 199 octogenarians, using laparotomy for 116 patients (group 1) and laparoscopic surgery for 83 patients (group 2). The mean age was 84.3 years for the laparotomy patients and 84.7 years for the laparoscopic patients. The American Society of Anesthesiology (ASA) scores was comparable between groups 1 and 2. Colorectal adenoma was the most common indication for surgery in both groups: for 77.6% of the group 1 patients and 54.2% of the group 2 patients. Right colectomy was the most frequently performed operation in group 2: for 57.8% of the group 2 patients and 31% of the group 1 patients (p = 0.0003). Open resections had a higher mean blood loss in both group 1 (286 ml) and group 2 (152 ml) (p = 0.0002), and more patients required intraoperative transfusions (p = 0.005) despite similar operative times. The conversion rate in the laparoscopic group was 25.3%. The patients in the laparoscopic group had less morbidity, both overall and clinically, than the open group (p < 0.05). The median hospital stay was 8 days in group 1 and 6 days in group 2 (p = 0.0065). The rate of major surgical complications was similar in the two groups of patients: 6% in group 1 and 4.8% in group 2. The reoperation rate was 2.6% in group 1 and 3.6% in group 2 (p > 0.05). The mortality rate was 3.4% in group 1 and 2.4% in group 2.
Laparoscopic colorectal resection was effective and safe for octogenarians, with less blood loss and faster postoperative recovery. The morbidity rate is lower than for traditional laparotomy.

ABSTRACT: This study investigated the risk factors related to artificial bowel sphincter infection, complications, and failure.
Complications may occur at any time after artificial bowel sphincter implantation. Early-stage complication is defined as any complications that occurred before artificial bowel sphincter activation, whereas late-stage complications are defined as any complications that occurred after device activation. Assessment of the outcomes of all artificial bowel sphincter operations included evaluation of factors related to patient demographics, operative procedures, and postoperative events.
From January 1998 to May 2007, 51 artificial bowel sphincter implantations were performed in 47 patients (43; 84.3% female) with a mean age of 48.8 +/- 12.5 (range, 19-79) years and a mean incontinence score of 18 +/- 1.4 (range, 0-20). In 24 patients (54.5%), the etiology of incontinence was secondary to imperforate anus; 15 (24.2%) patients had obstetric injury or anorectal trauma. Twenty-three (41.2%) artificial bowel sphincter implantations became infected, 18 (35.3%) of which developed early-stage infection, whereas 5 (5.9%) had late-stage infection. One patient in the latter group had associated erosion, and two patient had fistula formation. Late-stage complications continued to increase with time. Multivariate analysis revealed that the time between artificial bowel sphincter implantation and first bowel movement and a history of perineal sepsis were independent risk factors for early-stage artificial bowel sphincter infection.
The time from implantation to first bowel movement and history of perineal infection were risk factors for early-stage artificial bowel sphincter infection and failure. Late-stage failures were more often the result of device malfunction and indicated the need for mechanical refinement.

ABSTRACT: This study was designed to analyze the efficacy of the Cook Surgisis AFP anal fistula plug for the management of complex anal fistulas.
This was a retrospective review of all patients prospectively entered into a database at our institution who underwent treatment for complex anal fistulas using Cook Surgisis AFP anal fistula plug between July 2005 and July 2006. Patient's demographics, fistula etiology, and success rates were recorded. The plug was placed in accordance with the inventor's guidelines. Success was defined as closure of all external openings, absence of drainage without further intervention, and absence of abscess formation.
Thirty-five patients underwent 39 plug insertions (22 men; mean age, 46 (range, 15-79) years). Three patients were lost to follow-up, therefore, 36 procedures to be analyzed. The fistula etiology was cryptoglandular in 31 (88.6 percent) patients and Crohn's disease associated in the other 4 (11.4 percent). There were 11 smokers and 3 patients with diabetes. The mean follow-up was 126 days (standard = 69.4). The overall success rate was 5 of 36 (13.9 percent). One of the four Crohn's disease-associated fistulas healed (25 percent) and 4 of 32 (12.5 percent) procedures resulted in healing of cryptoglandular fistulas. In 17 patients, further procedures were necessary as a result of failure of treatment with the plug. The reasons for failure were infection requiring drainage and seton placement in 8 patients (25.8 percent), plug dislodgement in 3 (9.7 percent), persistent drainage/tract and need for other procedures in 20 patients (64.5 percent).
The success rate for Surgisis AFP anal fistula plug for the treatment of complex anal fistulas was (13.9 percent), which is much lower than previously described. Further analysis is needed to explain significant differences in outcomes.

ABSTRACT: The aim of this study was to review our experience with gracilis muscle interposition for complex perineal fistulas.
A retrospective review of all patients who underwent repair of perineal fistula using the gracilis muscle between 1995 and 2007 was undertaken. Patients were divided into 2 groups according to the fistula type by gender: females (rectovaginal and pouch-vaginal) and males (rectourethral).
Gracilis interposition was performed in 53 patients. Seventeen women underwent 19 gracilis interpositions for 15 rectovaginal and 2 pouch-vaginal fistulas; 76% had a mean of (1-4) (mean of 2) prior failed attempt at repair. Eight patients experienced at least one postoperative complication. Two women required a second gracilis interposition. Thirty-three percent of the Crohn's disease-associated fistulas successfully healed; 75% without Crohn's successfully healed.Thirty-six males underwent gracilis interposition for rectourethral fistulas, mainly due to prostate cancer treatment; 13 (36%) had a mean of 1.5 (range 1-3) failed prior repairs. Seventeen patients experienced postoperative complications. The initial success rate in men with rectourethral fistulas was 78%. After successful second procedures in 8 patients, the overall clinical healing rate was 97%.
The gracilis muscle transposition is a safe and effective method of treating complex perianal fistulas.

ABSTRACT: To evaluate women's sexual function, self-esteem, body image, and health-related quality of life after colorectal surgery.
Current literature lacks prospective studies that evaluate female sexuality/quality of life after colorectal surgery using validated instruments.
Sexual function, self-esteem, body image, and general health of female patients undergoing colorectal surgery were evaluated preoperatively, at 6 and 12 months after surgery, using the Female Sexual Function Index, Rosenberg Self-Esteem scale, Body Image scale and SF-36, respectively.
Ninety-three women with a mean age of 43.0 +/- 11.6 years old were enrolled in the study. Fifty-seven (61.3%) patients underwent pelvic and 36 (38.7%) underwent abdominal procedures. There was a significant deterioration in overall sexual function at 6 months after surgery, with a partial recovery at 12 months (P = 0.02). Self-esteem did not change significantly after surgery. Body image improved, with slight changes at 6 months and significant improvement at 12 months, compared with baseline (P = 0.05). Similarly, mental status improved over time with significant improvement at 12 months, with values superior than baseline (P = 0.007). Physical recovery was significantly better than baseline in the first 6 months after surgery with no significant further improvement between 6 and 12 months. Overall, there were no differences between patients who had abdominal procedures and those who underwent pelvic dissection, except that patients from the former group had faster physical recovery than patients in the latter (P = 0.031). When asked about the importance of discussing sexual issues, 81.4% of the woman stated it to be extremely or somewhat important.
Surgical treatment of colorectal diseases leads to improvement in global quality of life. There is, however, a significant decline in sexual function postoperatively. Preoperative counseling is desired by most of the patients.

ABSTRACT: Constipation is a common gastrointestinal complaint that can cause significant physical and psychosocial problems. It has been categorized as slow transit constipation, normal transit constipation, and obstructed defecation. Both the definition and pathophysiology of constipation are unclear, but attempts to describe each of the three types have been made. Slow transit constipation, a functional colonic disorder represents approximately 15 to 30% of constipated patients. The theorized etiologies are disorders of the autonomic and enteric nervous system and/or a dysfunctional neuroendocrine system. Slow transit constipation can be diagnosed with a complete history, physical exam, and a battery of specific diagnostic studies. Once the diagnosis is affirmed and medical management has failed, there are several treatment options. Biofeedback, sacral nerve stimulation, segmental colectomy, and subtotal colectomy with various anastomoses have all been used. Of those treatment options, a subtotal colectomy with ileorectal anastomosis is the most efficacious with the data to support its use.

ABSTRACT: Solitary rectal ulcer syndrome (SRUS) is a rare disorder often misdiagnosed as a malignant ulcer. Histopathological features of SRUS are characteristic and pathognomonic; nevertheless, the endoscopic and clinical presentations may be confusing. The aim of the present study was to assess the clinical findings, surgical treatment, and outcomes in patients who suffer from SRUS.
A retrospective chart review was undertaken, from January 1989 to May 2005 for all patients who were diagnosed with SRUS. Data recorded included: patient's age, gender, clinical presentation, past surgical history, diagnostic and preoperative workup, operative procedure, complications, and outcomes.
During the study period, 23 patients were diagnosed with SRUS. Seven patients received only medical treatment, and in three patients, the ulcer healed after medical treatment. Sixteen patients underwent surgical treatment. In four patients, the symptoms persisted after surgery. Two patients presented with postoperative rectal bleeding requiring surgical intervention. Three patients developed late postoperative sexual dysfunction. One patient continued suffering from rectal pain after a colostomy was constructed. Median follow-up was 14 (range 2-84) months.
The results of this study show clearly that every patient with SRUS must be assessed individually. Initial treatment should include conservative measures. In patients with refractory symptoms, surgical treatment should be considered. Results of anterior resection and protocolectomy are satisfactory for solitary rectal ulcer.

ABSTRACT: The majority of colorectal carcinomas diagnosed are adenocarcinomas. Squamous cell carcinomas (SCC) of the rectum are rare tumors, and were reported as rare complication of inflammatory bowel disease. Surgery is the most effective therapy; and adjuvant chemotherapy and radiotherapy should also be considered. We report two cases of ulcerative colitis-associated SCC of the rectum. The lesions were treated with chemoradiotherapy with complete response.

ABSTRACT: The classification of cancers of the rectum into a staging system with both therapeutic and prognostic applications has been
the goal of pathologists and clinicians for the greater part of the last century. Different staging systems for colorectal
cancer are in use today; however, the majority are modifications of a common framework using similar nomenclature with the
unfortunate results of inconsistencies and confusion. Most staging systems rely on examination of the pathologic specimen
as well as information gained during surgery. Thus, they are useful only in the postoperative setting and have little use
for the purpose of preoperative therapy. Cuthbert Dukes1 declared in 1932 “if it would be possible to decide the category
of the case before operating, this would be very useful information.” As the therapeutic options available for the treatment
of rectal cancer increase, the ability to accurately stage a rectal tumor preoperatively takes on greater importance. Accurate
and reproducible preoperative staging provides uniformity among numerous investigative centers; specifically those involved
in adjuvant preoperative therapy trials. Finally, the ability to stage the tumor preoperatively permits the physician to convey
more accurate information to the patient and the family with regard to therapeutic options and prognosis.

ABSTRACT: Much debate has revolved around whether patients with mucosal ulcerative colitis (MUC) receiving immunosuppression should be weaned off immunosuppressives before undergoing ileal pouch surgery. Therefore, the aim of this study was to assess the affect of immunosuppressive drugs on postoperative complications after ileoanal pouch surgery.
A retrospective medical record review of patients with MUC who underwent ileal pouch surgery while taking immunosuppressive drugs such as azathioprine, 6-mercaptopurine (6-MP), methotrexate, and cyclosporin A was performed. Postoperative complications in the study group were compared to three matched groups: patients with MUC who had ileoanal pouch surgery while taking systemic steroids, patients with MUC not receiving any immunosuppressive drugs, and patients with familial adenomatous polyposis.
Twenty-two patients with MUC who underwent ileoanal pouch surgery while taking immunosuppressive drugs were identified from a prospectively entered database of patients who had this surgery between 1988 and 2005. All but two patients underwent temporary fecal diversion. Fifteen patients were taking 6-MP or azathioprine; six were on cyclosporine A, and one both on azathioprine and cyclosporine A. Fifteen patients were also taking steroids at the time of ileoanal pouch surgery. Early (within 30 days of surgery) and late complications occurred in 36 and 50% of the study group patients, respectively, but did not significantly differ from a matched group of patients with MUC who did not take immunosuppressive drugs. Patients with familial adenomatous polyposis had a significantly lower long-term complication rate.
This retrospective case-matched study suggests that the use of immunosuppressive drugs and cyclosporine A may not be associated with an increased rate of complications after ileoanal pouch surgery.

ABSTRACT: Quality of life is affected by the creation of a stoma. To assess the validity of the Ostomy Function Index in patients with a stoma, a prospective survey was conducted from July 2000 to September 2001 among patients participating in local United Ostomy Association chapters (N = 99; 55 with a colostomy and 44 with an ileostomy). The Short Form 36 general health survey, Fecal Incontinence Quality of Life Scale, and the proposed Cleveland Clinic Florida Ostomy Function Index were used to assess general health and stoma function in patients with an ostomy. The average proposed function index score (7 = excellent function, 35 = poor function) was 11.97 (range 7 to 22). The proposed function Index correlated with the Fecal Incontinence Quality of Life Scale and the physical and mental component scales of the SF-36 (P < 0.05). The correlation between the proposed function index and the Fecal Incontinence Quality of Life Scale was stronger in colostomy than in ileostomy patients. With the exception of the SF-36 role-emotional domain in ileostomy patients, the function index correlated with all SF-36 scales (P <0.05) in both patient groups. The results of this study suggest that ostomy function is variable and correlates with quality of life and that the Fecal Incontinence Quality of Life Scale offers a limited assessment of quality of life in colostomy patients. The Cleveland Clinic Florida Ostomy Function Index offers an objective assessment of ostomy function that reflects on quality of life. Additional studies to refine measurement of quality of life in stoma patients are warranted.

ABSTRACT: A colostomy offers definitive treatment for individuals with fecal incontinence (FI). Patients and physicians remain apprehensive regarding this option because the quality of life (QOL) with a colostomy is presumably worse than living with FI. The aim of this study, therefore, was to compare the QOL of colostomy patients to patients with FI.
A cross-sectional postal survey of patients with FI or an end colostomy was undertaken. QOL measures used included the Short Form 36 General Quality of Life Assessment (SF-36) and the Fecal Incontinence Quality of Life score (FIQOL).
The colostomy group included 39 patients and the FI group included 71 patients. The average FI score for FI group was 12 +/- 4.9 (0 = complete continence, 20 = severe incontinence). In the colostomy group the average colostomy function score was 12.9 +/- 3.8 (7 = good function, 35 = poor function). Analysis of the SF-36 revealed higher social function score in the colostomy group compared to the FI group. Analysis of the FIQOL revealed higher scores in the coping, embarrassment, lifestyle scales, and depression scales in the colostomy group compared to the FI group.
A colostomy is a viable option for patients who suffer from FI and offers a definitive cure with improved QOL.

ABSTRACT: Compliance rates for colorectal cancer screening have been reported as low, and ignorance is the most common factor sighted to explain this. The aim of this study was to determine screening compliance among colorectal surgeons assumed to be educated of the risks of colorectal cancer.
A postal survey was distributed to the members of the American Society of Colon and Rectal Surgeons.
A total of 1195 members were surveyed. All respondents indicated that they advocate screening. Colonoscopy every 10 years and annual fecal occult blood testing were the most common strategies advocated to individuals with baseline risk. Colonoscopy every 5 years and annual fecal occult blood testing were the most common strategies advocated to patients with a first-degree relative with polyps or cancer. Most of these colorectal surgeons initiated their screening before 50 years of age.
Colorectal cancer screening compliance is high among members of the American Society of Colon and Rectal Surgeons. These rates may be the result of awareness of the risks of colorectal cancer.

ABSTRACT: Pouch-vaginal fistula (PVF) is a devastating complication after restorative proctocolectomy with ileal pouch anal anastomosis (IPAA). The aim of this study was to evaluate the surgical management of PVF.
After Institutional Review Board approval, all patients treated for PVF between 1988 and 2003 were retrospectively reviewed. Success of treatment was defined as the complete absence of symptoms or no radiologic evidence of fistula.
The study included 23 female patients; indications for IPAA were mucosal ulcerative colitis in 20 (87%), indeterminate colitis in 1 (4.3%), and familial adenomatous polyposis in 2 (8.7%) patients. Seven patients with mucosal ulcerative colitis were postoperatively diagnosed with Crohn's disease. Mean time interval from initial IPAA to development of symptomatic fistula was 17.2 months. Mean number of surgical treatments was 2.2. Overall, success was achieved in 17 (73.9%) patients at a mean followup of 52.3 months. Fistulas in patients with Crohn's disease occurred relatively late after IPAA (p = 0.015) and required a median of three (p = 0.001) surgical procedures, compared with patients without Crohn's disease. Pelvic sepsis after original IPAA occurred in eight (35.8%) patients, four (50%) of whom ultimately required pouch excision.
Fecal diversion and local procedures are effective in the majority of patients with PVF after IPAA. Patients with Crohn's disease tend to have a delayed onset of fistula occurrence and require more extensive surgical management. Pelvic sepsis can be a predictive factor of poor outcomes.

ABSTRACT: The surgical option of choice in most patients with mucosal ulcerative colitis or familial adenomatous polyposis is restorative proctocolectomy with ileal pouch anal anastomosis. The tension-free anastomosis is one of the most critical steps but may be technically difficult or impossible in some patients because of shortened small bowel mesentery. Various techniques have been described to increase the length of small bowel mesentery. These techniques usually involve selective division of mesenteric blood vessels and meticulous dissection. We describe a new technique of stepladder transverse, transmesenteric incisions in the avascular windows of small bowel mesentery. This provides additional small bowel length without compromising blood supply to the pouch and a simple and safe method of increasing the length of small bowel mesentery. To date, no complications have been reported using this technique.

ABSTRACT: Various surgical treatments exist for horseshoe abscesses and fistulae, including posterior midline sphincterotomy, catheter drainage, cutting and draining setons, and advancement flaps. The aim of this study was to evaluate the long-term results of patients treated for these complex anorectal problems.
A retrospective review was undertaken of patients with a diagnosis of horseshoe abscess, horseshoe fistula, postanal space abscess, or postanal space fistula from 1990 to 2001. Long-term follow-up was accomplished by telephone questionnaire.
Thirty-one patients were identified, of whom 17 (54.8%) had a diagnosis of Crohn disease. The diagnosis at presentation included unilateral (ischiorectal) abscess (32.3%), bilateral horseshoe abscess (51.6%), bilateral horseshoe fistula (9.7%), and postanal space abscess (6.4%). Endoanal ultrasonography was used during the preoperative evaluation in 11 patients (35.5%). After referral to our institution, patients underwent a median of four operations (range, 1 to 9). At a mean follow-up of 49.3 months, 60.7% of patients had either healed perineal disease or were asymptomatic with controlled disease. Patients who had a posterior midline sphincterotomy were more likely to be asymptomatic (P=.047). Patients who had a diagnosis of Crohn disease required more operations than those without Crohn disease (3 vs 1.86, P=.02). Only patients who had a diagnosis of Crohn disease had a stoma at their last follow-up (4 of 17, 23.5% vs 0 of 11, 0%; P=.05).
Patients with horseshoe abscess or fistulae often require multiple operations for treatment but can expect reasonable rates of long-term success in controlling or curing their disease. Those who undergo posterior midline sphincterotomy seem to benefit with higher rates of improved symptoms. Patients with a diagnosis of Crohn disease may fare less well. The role of endoanal ultrasonography in directing therapy remains to be defined.

ABSTRACT: Narcotics are routinely used to decrease postoperative pain after laparotomy. But they are associated with unwarranted side effects. The aim of this study was to assess the effectiveness of local perfusion of bupivacaine in decreasing narcotic consumption after midline laparotomy.
We performed a prospective, randomized, double blind study involving patients who underwent a midline laparotomy with subsequent wound closure. Patients were randomized to receive a 72-hour continuous wound perfusion through the ON-Q pain management system (I Flow Corporation) of the local anesthetic bupivacaine (0.5%, study group) or 0.9% NaCl (control group). In addition, all patients received standardized intraoperative analgesia and postoperative morphine patient-controlled analgesia. Total postoperative analgesic requirement, pain control, recovery of bowel function, and complications were recorded.
Seventy patients were recruited: 35 in the study group (mean age, 55.7 years) and 35 in the control group (mean age, 58.8 years). There was no difference in overall postoperative pain scores. Patients in the study group reported earlier ambulation as compared with the control group. Mean (+/-SD) daily narcotic requirements were significantly less in the study group versus the control group (33.7+/-32 mg versus 60.1+/-62 mg, respectively; p=0.03). Patients in the study group made 50% fewer attempts to receive patient-controlled analgesia (p=0.011). But there was no significant difference in length of hospitalization or time to first bowel movement.
This preliminary pilot study revealed that the ON-Q pain management system after midline laparotomy, as part of a multimodal approach, is an effective approach to postoperative pain control.

ABSTRACT: Solitary rectal ulcer syndrome is a poorly understood clinical condition, and the schema of treatment has not yet been defined. This study reviewed the clinical spectra and outcome of various surgical treatments in patients with solitary rectal ulcer syndrome. The medical records of all patients with solitary rectal ulcer syndrome between 1992 and 1998 were retrospectively reviewed. Patients in the study population with symptoms and histopathologic findings suggestive of solitary rectal ulcer syndrome were placed in the primary solitary rectal ulcer syndrome group, and patients who underwent surgery for other diseases in whom histopathology confirmed concomitant solitary rectal ulcer syndrome were in the incidental group. Clinical features and outcomes of surgical treatment were documented. Improvement was considered as resolution of presenting symptoms, and non-improvement was considered if presenting symptoms persisted or worsened. The study cohort comprised 49 patients: 20 in the primary group and 29 in the incidental group. Ulcerative morphology was seen predominantly in the primary group (70%); erythematous (45%) and polypoid lesions (34%) were predominant in the incidental group (P = .0025). Clinical improvement after surgery was seen in 74% of patients with primary and 79% with incidental solitary rectal ulcer syndrome (P = NS). Manifestations such as tenesmus and digitation correlated with poorer outcome after surgery in both groups. Solitary rectal ulcer syndrome is a clinical condition associated with functional anorectal evacuatory disorders. The results of this study show the positive role of surgical treatment for underlying functional disorders in the improvement of incidental solitary rectal ulcer syndrome.

ABSTRACT: Many surgical methods have been described for the treatment of full-thickness rectal prolapse. Rarely, unusually large lengths of colon must be excised, thus resulting in a significant loss of the absorptive function of the remaining colon. We present an unusual case in which an extraordinary length of the colon was excised and a perineal reservoir was created in the form of a colonic J-pouch to improve continence.
