Anal dysplasia as an incidental finding: the importance of specimen evaluation.

AIM: The incidence of anal squamous cell carcinoma (SCC) has increased dramatically in the USA. The squamous intraepithelial lesion has been identified as a precursor lesion to SCC, stratifying the abnormality into low grade or high grade. There have been studies on the prevalence of incidentally found SCC in haemorrhoidectomy specimens, but there are no studies to date on the incidence of dysplasia. The purpose of this study was to establish a baseline incidence of dysplasia that provides helpful information for future epidemiological studies. METHODS: This is a retrospective review of patients who underwent haemorrhoidectomy from 2005 to 2019. Pathology regarding the type of dysplasia, medications, and diagnoses that may predispose to immunosuppression were collected. RESULTS: In all, 810 patients with a mean age of 51.7 (range 20-91) years underwent haemorrhoidectomy. Eighteen (2.2%) of the patients had abnormal pathology (low-grade squamous intraepithelial lesion, 3; high-grade squamous intraepithelial lesion, 12; SCC, 2; adenocarcinoma, 1). Thirty-seven (4.5%) of the entire cohort had some risk factors for immunosuppression: chronic steroid use (nine), human immunodeficiency virus (HIV) (13), biologic medications (six), transplant recipients (two) and immunocompromising diseases (four). Only 4/18 patients had an immunosuppression risk in that all four of these patients were HIV-positive. Surveillance following excision was undertaken for an average of 6 (range 1-12) months, during which time four patients underwent a repeat biopsy. DISCUSSION: Anal dysplasia found in an otherwise asymptomatic population has a prevalence of 2.2%. This finding supports the routine examination of benign anorectal specimens undergoing microscopic examination. Interestingly, the majority of the patients identified had no immunosuppressant risk factors.

Short-term outcome of infliximab and other medications on patients with inflammatory bowel disease undergoing ileostomy reversal.

AIM: We evaluated the impact of immunosuppressive drugs on the short-term outcome following loop ileostomy closure in patients with inflammatory bowel disease. METHOD: Data on 249 patients with inflammatory bowel disease, who underwent loop ileostomy closure from 2001 to 2008, were retrospectively reviewed from a prospectively maintained database. Patients were distributed among groups according to the inflammatory bowel disease drugs used. Comorbidity, diagnosis, intra-operative and postoperative morbidity and length of stay data were analysed. Patients in group (INF) were receiving infliximab with or without other immunosuppressive agents (28), patients in group (S) were receiving only steroids (72) and those, in group III (S&I) were on steroids plus immunosuppressive agents, other than infliximab (35). Patients in group (ND) had not received any immunosuppressive agents for 2 months and served as the control group (114). RESULTS: Postoperative complication rates (wound infection, hernia, obstruction, intra-abdominal abscess, leakage, enterocutaneous fistula and sepsis) occured in 4.0, 12.0, 14 and 17.0% of patients in the four groups (P > 0.05). Reoperation was needed in 3.0% (2) of patients in group S, 6.0% (2) in S&I and 3.0% (3) in C groups, and the mean hospital stay was 4.6 (± 2.1), 5.6 (± 4.6), 5.2 (± 4.7) and 5.2 (± 6) days in groups INF, S, S&I and ND, respectively. There was no mortality. CONCLUSION: There were no significantly increased postoperative complications after ileostomy closure in patients who received infliximab or other immunosuppressive medications compared with patients who did not.

Prophylactic ureteric catheters in laparoscopic colorectal surgery.

BACKGROUND: The purpose of this study was to evaluate the use of ureteric catheter placement in laparoscopic colorectal surgery and to assess the morbidity related to this procedure. METHODS: Between 1994 and 2001, 313 elective laparoscopic colorectal surgeries were performed. Patients with and without ureteric catheters were retrospectively analyzed. RESULTS: Catheter placement was attempted in 149 patients (catheter group) and was not attempted in 164 (controls). There were no significant differences between groups in the number of patients with prior colorectal resection (p=0.286) or other abdominal surgery (p=0.074). Crohn's disease and diverticulitis were more common in the catheter group than among controls (p<0.001). Concomitant intra-abdominal fistula or abscess was present in 29 patients (19.5%) in the catheter group vs. 14 (8.5%) in the control group (p=0.005). The duration of surgery was longer in the catheter group (p=0.001). There were no significant differences in conversion, duration of bladder catheter placement, or length of hospital stay. Urinary tract infection occurred in 3 patients (2.0%) in the catheter group and 7 (4.3%) in the control group (p=0.257) and urinary retention occurred in 3 patients (2.0%) and 11 patients (6.7%), respectively (p=0.045). No intraoperative ureteric injuries occurred in either group. CONCLUSION: Ureteric catheter placement was successful in most cases and was not associated with intraoperative injuries. The increased length of surgery in patients with ureteric catheter placement may attest to the increased severity of pathology in these patients.

Imbrication of the external anal sphincter may yield similar functional results as overlapping repair in selected patients.

OBJECTIVE: Overlapping external anal sphincter repair is the preferred procedure for incontinent patients with functional yet anatomically disrupted anterior external anal sphincter. When incomplete disruption, thinning or technically difficult mobilization of the external anal sphincter occurs, imbrication without division may be the more feasible surgical option. The aim of the study was to assess retrospectively the indications for external anal sphincter imbrication in patients who underwent either overlapping external anal sphincter repair or external anal sphincter imbrication, and to compare the success rates. METHOD: Patients who had external anal sphincter repair and follow up of at least 3 months were studied. Fecal incontinence was measured using the validated Wexner fecal Incontinence Scoring system (0 = perfect continence, 20 = complete incontinence); postoperative scores 0-10 were interpreted as successful, and scores of 11-20 as failures. RESULTS: A total of 131 females who had anal sphincter repair between 1988 and 2000 were analysed. One hundred and twenty-one patients had overlapping external anal sphincter repair (group I), and 10 had external anal sphincter imbrication (group II). Indications for external anal sphincter imbrication were attenuation of the external anal sphincter without overt defect (n = 5), partial disruption of external anal sphincter with muscle fibres bridging the scar (n = 2), thick bulk of scar between the muscle edges (n = 2), and wide lateral retraction of the muscle edges (n = 1). There were no statistically significant differences between the groups relative to preoperative incontinence score (16.5 vs 16.5, P = 0.99), pudendal nerve terminal motor latency assessment (left 9.6%vs 0.0%, P = 0.19; right 13.4%vs 11.1%, P = 0.84), and extent of electromyography pathology (61%vs 47%, P = 0.30). The patients in group I were younger than those in group II (mean age 50.8 years vs. 61.7 years, respectively; P = 0.052) and the length of follow-up was significantly longer (32.3 months vs 14.3 months, respectively; P < 0.0001). Both procedures had similar success rates (59.5%vs 60%; P = 0.98). CONCLUSION: Imbrication of the external anal sphincter may yield similar results as overlapping external anal sphincter repair in patients with incomplete external anal sphincter disruptions, external anal sphincter attenuation, and in patients presenting with wide lateral retraction of the muscle edges.

Do elderly patients benefit from laparoscopic colorectal surgery?

BACKGROUND: The steadily increasing age of the population mandates that potential benefits of new techniques and technologies be considered for older patients. AIM: To analyze the short-term outcomes of laparoscopic (LAP) colorectal surgery in elderly compared to younger patients, and to patients who underwent laparotomy (OP). METHODS: A retrospective analysis of patients who underwent elective sigmoid colectomies for diverticular disease or ileo-colic resections for benign disorders; patients with stomas were excluded. There were two groups: age < 65 years (A) and age >or= 65 years (B). Parameters included demographics, body mass index (BMI), length of operation (LO), incision length (LI), length of hospitalization (LOS), morbidity and mortality. RESULTS: 641 patients (M/F - 292/349) were included between July 1991 and June 2006; 407 in group A and 234 in group B. There were significantly more LAP procedures in group A (244/407 - 60%) than in group B (106/234 - 45%) - p = 0.0003. Conversion rates were similar: 61/244 (25%) in group A, and 25/106 (24%) in group B (p = 0.78). There was no difference in LO between the groups in any type of operation. LOS was shorter in patients in group A who underwent OP: 7.1 (3-17) days versus 8.7 (4-22) days in group B (p <0.0001), and LAP: 5.3 (2-19) days versus 6.4 (2-34) days in group B (p = 0.01). In both groups LOS in the LAP group was significantly shorter than in OP group. There were no significant differences in major complications or mortality between the two groups; however, the complication rates in the OP groups were significantly higher than in LAP and CON combined (p = 0.003). CONCLUSIONS: Elderly patients who undergo LAP have a significantly shorter LOS and fewer complications compared to elderly patients who undergo OP. Laparoscopy should be considered in all patients in whom ileo-colic or sigmoid resection is planned regardless of age.

Faecal incontinence in male patients.

OBJECTIVE: Data concerning faecal incontinence (FI) in men are lacking. The aim of this study was to evaluate the historical aetiology and contrast aetiologies in younger and older men suffering from FI. METHOD: After institutional review board approval, a retrospective chart review was undertaken of all patients with FI seen between 1999 and 2005. The data of male patients was further analysed to assess the impact of age and historical aetiology on FI. RESULTS: A total of 404 males were included, 203 patients were <70 years of age (group A) and 201 patients were >or=70 years of age (group B). The most common prior diagnosis in group A was perianal sepsis in 23 (11.3%) patients and symptomatic haemorrhoids in 20 (9.9%) patients; in group B it was prostate cancer in 57 (28.4%) patients, symptomatic haemorrhoids in 31 (15.4%) patients and neurological diseases in 18 (9%) patients. The most common prior procedure in group A was restorative proctectomy/proctocolectomy in 32 (15.8%) patients, fistulotomy or haemorrhoidectomy in 21 (10.3%) and 19 (9.4%) patients respectively. In group B, radiation therapy for prostate cancer was utilized in 48 (23.9%) patients and haemorrhoidectomy in 29 (14.4%) patients. Comparing group A and group B relative to diagnosis - perianal sepsis, perineal trauma, congenital disorders, HIV infection and anal cancer were more common in group A, whereas prostate cancer, neurological diseases and colon cancer were significantly more common in group B. CONCLUSION: Prostate cancer, symptomatic haemorrhoids, perianal sepsis, rectal cancer and a history of restorative rectal resection were common associations with FI in men. The aetiologies for FI in men vary with age.

Laparoscopic vs. open surgery for acute adhesive small-bowel obstruction: patients' outcome and cost-effectiveness.

BACKGROUND: Numerous studies have demonstrated the feasibility of laparoscopy in the management of acute adhesive small-bowel obstruction (AASBO). However, comparative data with laparotomy are lacking. The aim of this study was to compare laparoscopy and laparotomy for the treatment of AASBO in terms of patient outcome and cost-effectiveness. METHODS: A retrospective chart review of all patients who underwent surgery for AASBO from 1999 to 2005 was conducted. Data recorded included operative and postoperative course, among others. Operative and total hospital charges were estimated from the Patient Accounting System. RESULTS: Thirty-one patients who underwent laparoscopy were matched to a similar group of patients who underwent laparotomy. In the laparoscopy group, four patients (13%) had a laparoscopy-assisted procedure and ten patients (32%) were converted. The laparoscopy group was subdivided into laparoscopy, laparoscopy-assisted, converted, and assisted-converted subgroups. In the majority of the patients, AASBO was secondary to a single band. Overall morbidity was significantly higher in the laparotomy group (p = 0.007). Morbidity rates were statistically significant between the laparoscopy and assisted-converted subgroups (p = 0.0001) but not between the laparotomy group and assisted-converted subgroup (p = 0.19). Median hospital stay and median time to first bowel movement were significantly shorter in the laparoscopy group. Charge data were available for only the last three years of the study. Operative charges and total hospital charges were similar between the laparoscopy and the laparotomy groups (p = 0.14 and p = 0.10, respectively). There was a significant difference in total hospital charges between the laparoscopy subgroup and laparotomy group (p = 0.03). CONCLUSIONS: Laparoscopy for AASBO is associated with reduced hospital stay, early recovery, and decreased morbidity. Laparoscopy-assisted and converted surgeries do not differ significantly from laparotomy in regard to patient outcome. Operative and total hospital charges are similar for both laparoscopy and laparotomy.

Outcome of parastomal hernia repair with and without midline laparotomy.

BACKGROUND: Surgical options for parastomal hernia (PSH) repair are primary fascial, mesh repair, and relocation with or without midline laparotomy. Overall, recurrence rates are higher after fascial repairs than after relocation. However, stoma relocation may require a midline laparotomy with higher associated morbidity. The aim of this study was to assess the outcome of PSH repair with relocation with or without a midline laparotomy. METHODS: All patients who underwent PSH repair with relocation were identified from a clinical database. Data were collected by retrospective review of medical records including patient demographics, presenting symptoms, predisposing factors, type of surgery, postoperative complications, recurrence, and follow-up. Patients were divided into two subgroups, with or without a midline laparotomy. In patients without a laparotomy, the stoma was intraperitoneally mobilized, passed behind the abdominal wall, and delivered and matured through a premarked stoma site, across the midline. RESULTS: Between 1992 and 2001, a total of 27 patients underwent PSH repair with relocation of the stoma to the opposite side of the abdominal wall. Of these, the operation was performed without a midline laparotomy in 11 patients (41%). There were no significant differences in age, gender, body mass index, and the duration of hernia between the non-laparotomy and laparotomy groups. Prior abdominal surgery was recorded for 3 patients in the group without a laparotomy and for 9 patients in the group with a laparotomy (p=NS). Although not quantified, patients in the non-laparotomy group were less likely to have significant intraabdominal adhesions. Conversely, patients in the laparotomy group had more advanced adhesions. The operative time was longer in the group with a laparotomy than in the group without [96.8 (50-220) minutes vs. 123.9 (45-360) minutes; (p=NS)], and the mean hospital stay was significantly less in patients without vs. with a laparotomy [5.5 (SD=1.6) days vs. 9.5 (SD=3.8) days, respectively; (p<0.05)]. There was only one recurrence in the group without a laparotomy compared to 3 in the group with a laparotomy. The mean follow-up periods were 36.8 and 56.6 months in the groups without and with a laparotomy, respectively. The postoperative complications included wound infection that occurred in 3 patients in each group. CONCLUSIONS: PSH repair with relocation without laparotomy was associated with a significantly shorter hospital stay, possibly due to the lack of a midline abdominal wound. It may not be feasible in patients with significant intraabdominal adhesions.

Strategies of follow-up for colorectal cancer: a survey of the American Society of Colon and Rectal Surgeons.

BACKGROUND: The postoperative surveillance of patients who have undergone curative treatment for colorectal cancer (CRC) is controversial. The aim of this study was to investigate the follow-up practice of colorectal surgeons in the United States. METHODS: A postal survey was sent to 1641 active members of the American Society of Colon and Rectal Surgeons practicing in the United States to assess the frequency of follow-up and the methods used in the surveillance of asymptomatic patients following curative surgery for CRC. RESULTS: Only 582 (36%) of the questionnaires that were sent were returned fully completed. Of these, 173 surgeons (30%) followed their patients according to guidelines. Ninety-four percent of surgeons during the first year and 81% during the second year saw their patients regularly every 3 or 6 months. The most widely used tests were colonoscopy and carcinoembryonic antigen (CEA) testing. There was wide discrepancy in the frequency of follow-up and techniques employed, with only about 50% of surgeons following recommended practice. CONCLUSIONS: Surveillance strategies mainly rely on clinical examination, CEA monitoring and colonoscopy. No clear consensus on surveillance programs for CRC patients exists.

Does sodium hyaluronate- and carboxymethylcellulose-based bioresorbable membrane (Seprafilm) decrease operative time for loop ileostomy closure?

BACKGROUND: Adhesions can result in serious clinical complications and make ileostomy closure, which is relatively simple procedure into a complicated and prolonged one. The use of sodium hyaluronate and carboxymethyl cellulose membrane (Seprafilm) was proven to significantly reduce the postoperative adhesions at the site of application. The aim of this study was to assess the incidence and severity of adhesions around a loop ileostomy and to analyze the length of time and morbidity for mobilization at the time of ileostomy closure with and without the use of Seprafilm. METHODS: Twenty-nine surgeons from 15 institutions participated in this multicenter prospective randomized study. 191 patients with loop ileostomy construction were randomly assigned to either receive Seprafilm under the midline incision and around the stoma (Group I), only under the midline incision (Group II), or not to receive Seprafilm (Group III). At ileostomy closure, adhesions were quantified and graded; operative morbidity was also measured. RESULTS: All 3 groups were comparable relative to gender, mean age and number of patients with prior operations (26, 25 and 19, respectively). Group II patients were significantly more likely to have pre-existing adhesions than Group III patients (30.6% vs. 14.1%, p = 0.025). At stoma mobilization, significantly more patients in Group III than in Group I had adhesions around the stoma (95.2% vs. 82.3%, p = 0.021). Mean operative times were 27, 25, and 28 minutes, respectively (p = 0.38), with significant differences among sites. There was no significant difference in the number of patients needing myotomy or enterotomy (29, 27 and 24 patients, respectively), nor in the number of postoperative complications (7, 9 and 7 patients, respectively). CONCLUSIONS: When consistently applied, Seprafilm significantly decreased adhesion formation around the stoma but not operative times without any increase in the need for myotomy or enterotomy. These findings were not seen in the overall study population possibly due to the large number of surgeons using a variety of application techniques.

Do internal anal sphincter defects decrease the success rate of anal sphincter repair?

BACKGROUND: Anatomic anal sphincter defects can involve the internal anal sphincter (IAS), the external anal sphincter (EAS), or both muscles. Surgical repair of anteriorly located EAS defects consists of overlapping suture of the EAS or EAS imbrication; IAS imbrication can be added regardless of whether there is IAS injury. The aim of this study was to assess the functional outcome of anal sphincter repair in patients intraoperatively diagnosed with combined EAS/IAS defects compared to patients with isolated EAS defects. METHODS: The medical records of patients who underwent anal sphincter repair between 1988 and 2000 and had follow-up of at least 3 months were retrospectively assessed. Fecal incontinence was assessed using the Cleveland Clinic Florida incontinence score wherein 0 equals perfect continence and 20 is associated with complete incontinence. Postoperative scores of 0-10 were interpreted as success whereas scores of 11-20 indicated failure. RESULTS: A total of 131 women were included in this study, including 38 with combined EAS/IAS defects (Group I) and 93 with isolated EAS defects (Group II). Thirty-three patients (87%) in Group I had imbrication of a deficient IAS, compared to 83 patients (89%) in Group II. All patients had either overlapping EAS repair (n=121) or EAS imbrication (n=10). Mean follow-up was 30.9 months (range, 3-131 months). There were no statistically significant differences between the two groups relative to age (48.3 vs. 53.0 years; p=0.14), preoperative incontinence score (16.1 vs. 16.7; p=0.38), extent of pudendal nerve terminal motor latency pathology (left, 11.1% vs. 8%; p=0.58; right, 8.6% vs. 15.1%; p=0.84), extent of pathology at electromyography (54.8% vs. 60.1%; p=0.43), and length of follow-up (26.9 vs. 32.5 months; p=0.31). The success rates of sphincter repair were 68.4% for Group I versus 55.9% for Group II (p=NS). Both groups were well matched for incidence of IAS imbrication as well as age, follow-up interval, and physiologic parameters. The success rates of anal sphincter repair were not statistically significant between the two groups. CONCLUSION: A pre-existing IAS defect does not preclude successful sphincteroplasty as compared to repair of an isolated EAS defect. Thus, patients with combined anal sphincter defects should not be considered as poor candidates for sphincter repair.

Timing of restorative proctectomy following subtotal colectomy in patients with inflammatory bowel disease.

BACKGROUND: There is no general consensus regarding the timing of restorative proctocolectomy (RPC) in patients who have undergone subtotal colectomy with end ileostomy (STC). The aim of this study was to determine the impact of timing of RPC in patients who have undergone subtotal colectomy and end ileostomy for inflammatory bowel disease (IBD). METHODS: A retrospective medical record review of patients who had undergone RPC after STC was undertaken. Patients were divided into 3 groups according to timing of the completion proctectomy: 7 months. RESULTS: From 1990 to 2000, 91 patients had undergone RPC after STC for IBD. There were no statistically significant differences among the three groups relative to mean age, gender, final diagnosis, duration of disease, body mass index, comorbidity, extraintestinal manifestations, use of immunuosuppressives, or operative time. The number of intra-operative complications were significantly higher in the

Effects of radiotherapy on different histopathological types of rectal carcinoma.

BACKGROUND: Down staging by pre-operative chemoradiotherapy is currently considered part of the standard therapeutic approach to rectal carcinoma. The aim of this study was to assess the response to chemoradiotherapy of different histopathological types of rectal carcinoma with emphasis on the mucinous variant. METHOD: Between 1997 and 2002, 71 patients who received pre-operative chemoradiotherapy followed by surgery for rectal carcinoma were enrolled in the study. Staging of the rectal carcinoma was performed according to transrectal ultrasound findings (TN score) prior to the chemoradiotherapy. The chemoradiotherapy was followed by radical resection with mesorectal excision. All surgical specimens were examined by a single pathologist (MB). Pathological TN staging was assessed and tumour regression was graded according to a standard method (TRG1, complete response - TRG5 no response). Tumours were classified as mucinous or nonmucinous according to pre- and post-operative biopsy and specimen histopathological types. TN score change and TRG differences between groups were assessed. RESULTS: Tumour regression was seen after chemoradiotherapy in 94.4% of the patients, while in 5.6% of the patients no response was found. The change in TN score and TRG were correlated. Higher TRG was associated with a smaller decrease in TN staging. TRG was significantly lower in the nonmucinous compared to the mucinous group and the decrease in TN grade was significantly larger in the nonmucinous group. CONCLUSION: Mucinous carcinoma was associated with a lower response to pre-operative chemo-radiotherapy in this group of rectal carcinoma patients. Further studies are needed to determine its prognostic value.

Anatomic extent of colitis and disease severity are not predictors of pouchitis after restorative proctocolectomy for mucosal ulcerative colitis.

BACKGROUND: Pouchitis is a common complication following restorative proctocolectomy with ileal pouch anal anastomosis (RPC-IPAA) for mucosal ulcerative colitis (MUC). The aim of this study was to determine if perioperative anatomic extent and severity of disease are predictors of pouchitis. METHODS: All consecutive patients who underwent RPC-IPAA for MUC between 1988 and 2002 were retrospectively studied. Pouchitis was classified as acute, recurrent or refractory. Colectomy specimen slides were histopathologically evaluated by a single blinded pathologist (MB), who assessed extent and severity of disease. RESULTS: Of 112 patients assessed, 70 (62.5%) had some form of pouchitis at a median follow-up of 38 months (range, 1-204 months). No association was found between the extent or severity of disease and subsequent development of acute or chronic pouchitis. A positive correlation was found between the histopathologic score and the occurrence of clinical pouchitis (p=0.014). The presence of colonic metaplasia in the pouch biopsy was significantly correlated with a histopathologic diagnosis of pouchitis (p<0.0001, r=-0.449). CONCLUSIONS: Following RPC for MUC, the extent and severity of disease do not predict the subsequent development of pouchitis.

Biofeedback therapy for rectal intussusception.

BACKGROUND: Surgery for isolated internal rectal intussusception is controversial due to high morbidity. Therefore, there is interest in other forms of treatment that are safe and effective. The aim of this study was to determine outcome and identify predictors for success of biofeedback therapy in patients with rectal intussusception. METHODS: We retrospectively evaluated the results of electromyography (EMG)-based biofeedback in 34 patients with rectal intussusception without any other major pelvic floor or colonic physiologic disorder. RESULTS: A total of 34 patients (7 men) had undergone at least 2 biofeedback sessions. The patients had a mean age of 68.5 years (SD=11.4 years). In the 27 patients with constipation, the frequency of weekly spontaneous bowel movements (mean+/-SD) was 2.0+/-6.8 before and 4.1+/-4.6 after biofeedback (p<0.05). The frequency of weekly assisted bowel movements decreased from 3.8+/-3.5 before to 1.5+/-2.2 after therapy (p<0.005). The number of patients who experienced incomplete evacuation decreased from 17 (63%) to 9 (33%) (p<0.05). Thirty-three percent of patients had complete resolution of the symptoms, 19% had partial improvement, and 48% had no improvement. Patients with constipation lasting less than nine years had a 78% success rate vs. 13% in patients who were constipated more than 9 years (p<0.01). In seven patients with incontinence, the frequency of daily incontinence episodes decreased from 1.0+/-0.7 before to 0.07+/-0.06 after biofeedback (p<0.05). The fecal incontinence score decreased from 13.1+/-4.2 before to 4.6+/-3.6 after treatment (p<0.005). Two patients (29%) were completely continent following biofeedback, 2 had partial improvement, and 3 (43%) had no significant improvement. There was no mortality in either group. CONCLUSIONS: Biofeedback is a safe and effective treatment option for constipation and fecal incontinence due to rectal intussusception in patients who are willing to complete the course of treatment. Long-standing constipation is less effectively cured by biofeedback.

Ileal pouch anal anastomosis for ulcerative colitis is feasible for septuagenarians.

OBJECTIVE: Proctocolectomy and ileal pouch anal anastomosis (IPAA) has become the standard surgery for patients with mucosal ulcerative colitis (MUC). Although there is no absolute age limitation, there are concerns as to its use in elderly patients due to the risks of potential complications and poor function. The aim of this study was to assess the complications and outcome of patients over the age of 70 years with MUC who underwent IPAA. Results in these patients were compared to the results in a group of patients aged less than 70 years who had IPAA. METHODS: After Institutional Review Board approval, a retrospective review of the medical records of patients with MUC who underwent IPAA was undertaken. These patients were divided into four age groups: <30 years of age, 30-49 years, 50-69 years, >or=70 years. RESULTS: From 1989 to 2001, 330 patients underwent IPAA for preoperative clinical and histopathological and postoperative histopathologically confirmed MUC; 17 were aged>or=70 years. The mean hospital stay was 5.8 (SEM 0.7) days in the patients aged<70 years and 6.0 (SEM 0.4) days in the patients aged>or=70 years (P=0.911). Postoperative complications occurred in 39% of patients>or=70 years and in 40% in the <70 years group (P=0.08). Pouch failure occurred in two (11.8%) patients>or=70 years and in 6 (1.9%)<70 (P=0.2). CONCLUSION: IPAA is a safe and feasible option in MUC patients over the age of 70 with functional results similar to results seen in younger patients.

Quality of life after colectomy for colonic inertia.

BACKGROUND: Total abdominal colectomy (TAC) with ileorectal anastomosis represents the procedure of choice in patients with colonic inertia and relieves constipation in the majority of patients. The aim of this study was to assess postoperative long-term health related quality of life in these patients in relation to their functional outcome. METHODS: A consecutive series of patients with isolated colonic inertia who underwent TAC between 1993 and 1999 was identified from a clinical database and investigated in a cohort outcome study. Functional variables including the weekly number of bowel movements (BM), abdominal pain, bloating and distension, fecal incontinence, and the use of medications for BM assistance were assessed preoperatively and postoperatively. Main outcome measure was health-related quality of life assessed at follow-up using the SF-36 Health Survey. RESULTS: A total of 17 women with a mean age of 47.8 years (SD=14.3 years) were assessed and were followed postoperatively for 58.3+/-27.3 months. Preoperatively, all patients were constipated with less than one bowel movement per week, used laxatives, and experienced abdominal pain, bloating and distension. Postoperatively, all patients had some relief of constipation symptoms, with 3.7+/-2.8 bowel movements/day; 41% complained of abdominal pain, 65% of bloating, 29% required BM assistance, and 47% had occasional incontinence to gas or liquid stool. The SF-36 scores were significantly lower than those of the general population (p<0.005). In univariate regression analysis, postoperative abdominal pain was predictive for lower scores in general health and vitality and the need for BM assistance for lower scores in physical role functioning, social functioning, and emotional role limitations. CONCLUSIONS: After TAC, quality of life is significantly reduced in patients with colonic inertia despite successful relief of symptoms of constipation. Postoperative pain and functional impairment are predictive of lower quality of life scores.

Assessment of long-term quality of life after laparoscopic and open surgery for Crohn's disease.

OBJECTIVE: Surgery for Crohn's disease (CD) is associated with a high recurrence rate and quality of life (QOL) in these patients is controversial. The aim of this study was to assess QOL in patients after laparoscopic and open surgery for CD by two different validated instruments, a generic nonspecific score and a specific gastrointestinal QOL index. PATIENTS AND METHODS: Patients with CD who underwent elective laparoscopic or open ileocaecal resection with primary anastomosis between 1992 and 2000 were followed for recurrence and surgery-related complications. QOL was assessed by the SF-36 Health Survey containing a mental (MCS) and a physical (PCS) component summary score and by the Gastrointestinal Quality of Life Index (GIQLI) developed by Eypasch. RESULTS: Thirty-seven patients with a mean age of 48.8 +/- 18.4 years including 23 females and 14 males were evaluated at a mean follow-up of 42.6 +/-25.8 months (minimum of 8 months). Twenty-one (57%) patients underwent laparoscopic resection and 16 (43%) open surgery. Both groups were well matched for age, gender, ASA class and body mass index. Fourteen (38%) patients developed recurrent disease and 3 (8%) had postoperative incisional hernias. Overall, QOL scores were 103 +/- 26.8 for the GIQLI, 47.2 +/- 11.8 for the PCS, and 49.2 +/- 11.5 for the MCS. The GIQLI correlated well with the SF36, correlation coefficient = 0.68 for GIQLI vs PCS (95% CI, 0.41,0.95) and 0.67 for GIQLI vs MCS (95%CI, 0.39, 0.95), respectively. When compared to the general US population, mean GIQLI scores (-13.8, P = 0.002) and mean PCS scores (-4.7, P = 0.001) were significantly lower in these patients than in healthy individuals. In a multivariate analysis of impact factors on QOL, recurrence within the follow-up period was the single significant determinant reducing the PCS (-35.1, P = 0.026) and the GIQLI (-36.1, P = 0.018). CONCLUSION: QOL is significantly reduced in patients with CD at long-term follow-up after both laparoscopic and open surgery. Recurrence is the only factor adversely affecting QOL of CD patients in remission irrespective of the operative technique applied.

Topical tacrolimus (FK506) in the treatment of recalcitrant parastomal pyoderma gangrenosum associated with Crohn's disease: report of two cases.

INTRODUCTION: Pyoderma gangrenosum is a rare idiopathic skin disorder associated with other diseases, including inflammatory bowel disease. The commonest site is the skin, but sometimes it can occur in the parastomal region. Most of these cases respond to treatment with systemic corticosteroids and cyclosporin or local Kenalog injections. METHODS: The following are two cases of parastomal pyoderma in patients not responding to the standard measures. These patients were treated with topical tacrolimus. RESULTS: These patients showed dramatic improvement in one week with complete resolution and re-epithelialization of skin within two weeks. CONCLUSION: Pyoderma gangrenosum is a difficult problem to manage and its early resolution is important. In these two reported cases, the improvement was dramatic, therefore topical tacrolimus should be considered early in the management.

Perineal rectosigmoidectomy for rectal prolapse: role of levatorplasty.

BACKGROUND: The management of full thickness rectal prolapse remains controversial. Although abdominal approaches have a lower recurrence rate than do perineal operations, they are associated with a higher morbidity. The aim of this study was to compare the outcomes of perineal rectosigmoidectomy with and without levatorplasty. METHODS: Between 1989 and 1999, a total of 109 consecutive patients (10 men) underwent 120 perineal procedures. These patients were retrospectively evaluated in two groups on the basis of the type of surgery received: perineal rectosigmoidectomy (PRS) or perineal rectosigmoidectomy with levatorplasty (PRSL). Subsequent functional outcome and physiological parameters were assessed. RESULTS: The patients had a mean age of 75.7 years (range, 23.0-94.8 years) and they were followed for an overall mean (in both groups combined) of 28.0 months (range, 0.4-126.4 months) after surgery. Mean duration of surgery was 78.1 min (SD=25.9) and 97.6 min (SD=32.3) in PRS and PRSL, respectively ( p=0.002, unpaired t test). There was no significant difference between the two groups in terms of hospital stay, morbidity or mortality. Recurrence rates and mean time interval to recurrence were, respectively, 20.6% and 45.5 months in PRS compared to 7.7% and 13.3 months in PRSL ( p=0.049, chi-square test; p=0.001, unpaired t test). Both groups had significant improvements in postoperative incontinence score ( p<0.0001, Wilcoxon's matched-pairs signed-ranks test), however, there were no significant changes in anorectal manometric findings and pudendal nerve terminal motor latency assessment. CONCLUSIONS: Perineal rectosigmoidectomy with levatorplasty is associated with a lower recurrence rate and a longer time to recurrence than perineal rectosigmoidectomy alone. Levatorplasty should be offered to patients when a perineal approach for rectal prolapse is selected.
