Chances of cure are not compromised with sphincter-saving procedures for cancer of the lower third of the rectum.

BACKGROUND: The goal of this study was to compare patterns of recurrence and long-term outcome after sphincter-saving procedures (SSPs) and abdominoperineal resection (APR) in patients with tumors located in the lower third of the rectum. METHODS: We reviewed the charts of 1001 patients operated on for primary rectal adenocarcinoma between 1980 and 1991. All patients with tumors located between 5 and 7 cm from the anal verge and treated with curative intent were included. RESULTS: Of the 261 patients who met our criteria, 162 had undergone SSP and 99 had undergone APR. The local recurrence rates for SSP and APR were 8% and 11%, respectively (p = 0.41), and the distant metastases rates were 23% and 28%, respectively (p = 0.35). Recurrence and distant metastases rates for SSP and APR, respectively, did not differ by TNM classification: state I, 10% versus 9% (p = 0.9); stage II, 25% versus 43% (p = 0.13); and stage III, 56% versus 57% (p = 0.92). Five-year disease-free survival rates for SSP and APR patients were 70.5% and 62.3%, respectively (p = 0.2). CONCLUSIONS: Tumors in the lower third of the rectum can be treated with sphincter-saving procedures without compromising the chance of cure.

Management and causes of acute large-bowel obstruction.

Acute LBO has many possible causes. In the United States, the most common cause is colorectal carcinoma. Mechanical obstruction should be differentiated from pseudo-obstruction by contrast enema or colonoscopy because the treatments differ. The high postoperative mortality and morbidity of LBO compared with elective resection are explained by the multiple associated pathophysiologic changes of obstruction. Management of this condition requires careful assessment, awareness, and expertise in the current modalities of treatment. Gangrene and perforation should be avoided because they limit treatment options and are associated with an increase in mortality. We prefer, in most instances, to perform a single-stage procedure, which has the advantages of reduced hospital stay (and cost) and avoidance of a stoma. However, the appropriate treatment needs to be tailored to the individual situation. Recent developments in nonoperative decompressing procedures may demonstrate advantages in the future.

Factors associated with the occurrence of leaks in stapled rectal anastomoses: a review of 1,014 patients.

BACKGROUND: Despite improvement in surgical techniques and stapling devices during the last 10 years, colorectal anastomoses are still prone to leakage. The purpose of this study was to assess the performance and safety of stapled anastomoses in rectal surgery and to identify factors that influence the occurrence of anastomotic leaks. STUDY DESIGN: A review was undertaken of 1,014 patients who underwent stapled anastomoses to the rectum or anal canal for colorectal cancer or benign disease between 1989 and 1995 in a tertiary care institution. Indications for operations, comorbidities at admission, preoperative bowel preparation, stapler size, intraoperative events, associated surgical procedures, and clinical outcomes were tested for any association with anastomotic leak. RESULTS: A double stapled technique was used in 154 patients and a conventional single stapler technique was used in 860. Postoperative mortality was 1.6%, and the overall morbidity was 18.4%. Clinically apparent anastomotic leak developed in 29 patients (2.9%). Anastomotic dehiscence occurred in 22 of 284 patients (7.7%) after low stapling (within 7 cm from the anal verge) and in 7 of 730 patients (1%) after high stapling (p < 0.001). Diabetes mellitus, use of pelvic drainage, and duration of surgery were significantly related to the occurrence of anastomotic leak by the univariate analysis. Multivariate regression analysis identified an anastomotic distance from the anal verge within 7 cm as the only variable related to the occurrence of postoperative leak (p < 0.001). CONCLUSION: Low anastomoses were associated with a leak rate greater than with high colorectal anastomoses. We conclude that anastomoses to the rectum using the circular stapler can be done with low mortality and morbidity.

The risk of cancer and dysplasia among ulcerative colitis patients with primary sclerosing cholangitis.

BACKGROUND: Ulcerative colitis (UC) patients with primary sclerosing cholangitis (PSC) may have an increased risk for colonic dysplasia or cancer. They also may have higher levels of carcinogenic secondary bile acids and, thus, be more likely to develop cancer in the right side of the colon, where secondary bile acid concentrations are highest. METHODS: Since 1983, 1212 UC patients have undergone total proctocolectomy with ileal pouch-anal anastomosis at the Cleveland Clinic. All 27 patients with PSC were compared with the remaining 1185 patients in a historical cohort study. RESULTS: Dysplasia detected during cancer surveillance was the indication for surgery in 16 (59.5%) PSC patients and 136 (11.5%) controls [adjusted relative risk (RR), 6.9; 95% confidence interval (CI), 3.0-16.0]. Dysplasia or cancer was found in the resected specimen in 18 (66.7%) PSC patients and 145 (12.2%) controls (RR 10.4, CI 4.1-26.1). Right-sided cancers (proximal to the splenic flexure) were found in all four PSC patients with cancer and in 20 of 49 controls with cancer (RR 2.5, CI 1.3-5.4). CONCLUSIONS: UC patients with PSC are at a significantly increased risk for dysplasia or cancer. The high proportion of right-sided cancers supports the contention that secondary bile acids are carcinogenic and increase the likelihood of cancer in the proximal colon.

Quality of life after prophylactic colectomy and ileorectal anastomosis in patients with familial adenomatous polyposis.

BACKGROUND: Prophylactic colectomy or proctocolectomy is standard treatment for colorectal manifestation of familial adenomatous polyposis (FAP), a dominantly inherited disorder for which the risk of developing colorectal cancer in an untreated patient is close to 100 percent. Hereditary nonpolyposis colorectal cancer (HNPCC) is also dominantly inherited but has a lower risk of colorectal cancer than FAP and does not have a clinically obvious phenotype. The role of prophylactic colectomy in patients with HNPCC is controversial. PURPOSE: This study was performed to examine the outcome of colectomy and ileorectal anastomosis (IRA) so its use as a prophylactic procedure can be better evaluated. METHODS: Records of all patients undergoing IRA for FAP between 1985 and 1993 were reviewed. Demographic data and data about the operation were collected. Surgical outcome data included length of hospital stay, complications, bowel function, quality of life, and patient satisfaction. RESULTS: There were 51 patients with a median age of 28 years; 24 were male. All but eight patients were asymptomatic, and all had less than 1,000 polyps in the resected specimen. Mean surgery time was 3.5 hours, mean blood loss was 406 ml, and median length of hospital stay was seven days. There were no deaths, and eight patients (16 percent) had complications. Mean number of stools per day after median follow-up of 4.2 years was 3.6. Only 11 patients had nighttime stooling. Four patients reported seepage, 9 had some incontinence, and 16 had urgency. Quality of life, rated on a scale of 0 to 10, was 7 or above in 44 of 48 assessed patients. Quality of health was rated 7 or higher in all 48 patients, energy level was 7 or higher in 39 patients, and overall happiness with surgery was 7 or higher in 47 patients. CONCLUSIONS: Colectomy and IRA is a relatively safe operation that results in minimum disturbance of bowel function. Patient satisfaction is usually high. Prophylactic colectomy can be offered to HNPCC gene carriers with a greater understanding of the likely outcome of surgery.

Reoperative rates for Crohn's disease following strictureplasty. Long-term analysis.

BACKGROUND: In Crohn's disease, ten-year reoperative recurrence rates after resection range from 30 to 53 percent. To determine the effect of strictureplasty on reoperative "recurrence" rates, experience at a single tertiary care institution was reviewed. PATIENTS AND MATERIALS: Records of all patients who underwent strictureplasty for Crohn's disease from June 1984 to July 1994 at a tertiary care institution were reviewed. Data collected included duration of disease, medical and surgical history related to Crohn's disease, indications for strictureplasty, and longterm outcome. RESULTS: One hundred sixty-two patients (87 male) underwent 191 operations for a total of 698 strictureplasties (Heineke-Mikulicz, 617; Finney's, 81). Mean number of strictureplasties was three, and mean patient age was 36 years. No mortality occurred. Cumulative five-year incidence of reoperative recurrence was 28 percent (95 percent confidence interval, 18.8-37.2 percent), with a median follow-up of 42 (range, 1-120) months. Obstructive symptoms were relieved in 98 percent of patients. To determine whether any difference in reoperative rates exists between patients who have strictureplasty alone and those who have strictureplasty with bowel resection, we divided patients in two groups, those receiving strictureplasty alone and those undergoing stricutreplasty plus resection. For patients treated by strictureplasty alone (Group A, n = 52; 32 percent), cumulative reoperative rate at five years was 31 +/- 9.6 (+/-standard error) and for patients with concomitant bowel resection (Group B, n = 110; 68 percent), it was 27.2 +/- 5.4 (+/-standard error). No statistical difference was present between these two groups. Of patients undergoing strictureplasty alone (Group A), operative recurrence was managed by new stricutreplasty in seven, by restricutreplasty in two, and by bowel resection in one. Among patients in Group B (strictureplasty and concomitant bowel resection), new strictureplasty was performed in 11, restrictureplasty in 6, and bowel resection in 9. CONCLUSION: Strictureplasty is a safe and effective procedure for Crohn's disease in selected patients. Reoperative rates are comparable with resective surgery, and most recurrences occur at new sites.

Effect of systemic steroids on ileal pouch-anal anastomosis in patients with ulcerative colitis.

BACKGROUND: Long-term steroid therapy predisposes to postsurgical complications, especially in patients with inflammatory bowel disease. PURPOSE: This study was undertaken to determine incidence of early septic complications after ileal pouch-anal anastomosis (IPAA) in patients who are undergoing prolonged steroid therapy. METHODS: We reviewed charts of 692 patients undergoing restorative proctocolectomy and IPAA to treat ulcerative colitis. Incidence of early (within 30 days) septic complications and sepsis-related reoperations, in patients who were having high-dose (>20 mg of prednisone per day) and low-dose steroid therapy (<20 mg of prednisone per day) for more than one month before surgery, was compared with patients who were not receiving steroid therapy. Follow-up included an annual questionnaire and physical examination. RESULTS: Patients without steroid dose data recorded were excluded (n = 21). Of the 671 remaining patients, 310 received no steroids, 169 received low-dose steroids, and 192 received high-dose steroids. These three groups were similar in gender composition, age at surgery, types of anastomosis (stapled or handsewn), and incidence of diabetes mellitus, peripheral vascular disease, and obesity. Early septic complications were found in 18 (6 percent), 14 (8 percent), and 12 (6 percent) patients without steroid therapy, those having low-dose steroid therapy, and those having high-dose steroid therapy (P = 0.57), respectively. Sepsis- related reoperation rate (P = 0.73) and number of sepsis-related pouch excisions (P = 0.79) did not differ between groups. In patients undergoing IPAA without ileostomy, early septic complications were found in one (3.8 percent), two (20 percent), and five (50 percent) patients without steroid treatment, low-dose steroid therapy, and high-dose steroid therapy (P = 0.004), respectively. CONCLUSION: In patients who are undergoing IPAA with diversion for ulcerative colitis, prolonged systemic steroid therapy before surgery is not associated with increased septic complications.

Stapled ileal pouch anal anastomoses are safer than handsewn anastomoses in patients with ulcerative colitis.

BACKGROUND: One of the theoretic advantages of using a stapled versus handsewn ileal pouch anal anastomosis (IPAA) in restorative proctocolectomy is a reduction in septic complications. We performed this study to compare the incidence of early septic complications in patients undergoing restorative proctocolectomy with stapled or handsewn IPAA. PATIENTS AND METHODS: A chart review of 692 patients undergoing restorative proctocolectomy for treatment of ulcerative colitis was performed. The incidence of early septic complications in patients having stapled IPAA was compared to that in patients having handsewn IPAA. Follow-up studies included an annual questionnaire and physical examination. RESULTS: Of the 692 patients, 238 had handsewn IPAA and 454 had stapled IPAA; these two groups were similar in sex, duration of disease, age at surgery, and type of surgical procedure performed. In the handsewn IPAA group, 25 patients (10.5%) had 32 septic complications, and 24 required 89 reparations. In 7 patients, the pouch was excised. In the stapled IPAA group, 21 patients (4.6%) had 23 septic complications, and 14 required 40 reparations. One patient needed pouch excision. There were more patients (P=0.0001) with early septic complications, and more (P<0.0001) pouch excisions because of these complications, in patients with handsewn IPAA than in patients with stapled IPAA. The sepsis-related reoperation rates did not differ significantly. CONCLUSIONS: The stapled technique for IPAA has fewer septic complications and results in fewer sepsis-related pouch excisions, in our hands, than the handsewn technique technique, for treating patients with ulcerative colitis.

How safe is strictureplasty in the management of Crohn's disease?

BACKGROUND: Strictureplasty is a well-accepted technique in the management of selected patients with Crohn's disease. To determine the safety and optimal clinical setting for performing strictureplasty, perioperative complications and long-term outcomes need to be analyzed. PATIENTS AND MATERIALS: We retrospectively reviewed the charts of 162 patients (87 men, 75 women) with Crohn's disease who underwent strictureplasty between June 1984 and July 1994. Medical and surgical history, including medications and laboratory data, intraoperative findings, perioperative complications, and long-term follow-up data were recorded. RESULTS: These patients underwent 698 strictureplasties (Heineke-Mikulicz procedures, 617; Finney procedures, 81). Median hospital stay was 8 days. Perioperative septic complications were noted in 8 patients (5%); however, reoperation for sepsis was needed only in 5 patients. Five percent of patients developed prolonged ileus after strictureplasty. Symptomatic improvement after strictureplasty was achieved in 98% of patients. Restricture or new stricture or perforative disease was seen in 5% and 17% of patients, respectively, during a 42-month median follow-up period. CONCLUSIONS: Our findings show that strictureplasty is a good surgical option for stenosing small-bowel Crohn's disease, particularly in patients with multiple obstruction and in those vulnerable to short-bowel syndrome. Perioperative complications are few, and long-term results are gratifying.

Colonic fistulas.

Colonic fistulas are uncommon. They are frequently external but also occur internally to a number of organs. External fistulas are usually caused by a complication or are the result of a surgical procedure, such as leaking anastomosis or incision and drainage of an abscess resulting from an underlying pathologic condition.

Cardiovascular collapse during anesthesia in a patient with preoperatively discontinued chronic MAO inhibitor therapy.

We describe a patient in whom long-term monoamine oxidase (MAO) inhibitor therapy was discontinued 20 days before surgery with general anesthesia. This patient developed severe perioperative hypotension after administration of 10 mg of bupivacaine through an epidural catheter, which was corrected only after potent vasopressor therapy. We attribute this hemodynamic instability to attenuation of this patient's sympathetic tone based on several mechanisms: (1) residual effect of long-term administration of MAO inhibitor that caused a decrease in the number of beta-adrenergic receptors (adrenergic subsensitivity due to receptor down-regulation), (2) recovered MAO activity causing effective degradation of sympathetic amines, and (3) combined attenuating effects of general and epidural anesthesia on sympathetic tone.

Anal canal inflammation after ileal pouch-anal anastomosis. The need for treatment.

UNLABELLED: One technique used during restorative proctocolectomy to prevent loss of continence involves preservation of the anal canal. This technique retains a small amount of colonic mucosa and transitional mucosa that may become inflamed or develop dysplastic or neoplastic changes. PURPOSE: This study was designed to determine the presence and severity of anal canal inflammation and the need for treatment. METHOD: Records of 217 patients with mucosal ulcerative colitis who underwent restorative proctocolectomy with a stapled ileal pouch-anal anastomosis without anal mucosectomy from 1987 through 1990 were retrospectively reviewed. RESULTS: Anal canal inflammation was evident on both endoscopy and biopsy in 48 patients (22.11 percent); 18 patients (8.29 percent) had a normal ileal pouch (9 had symptoms; 5 required topical treatment), and 30 patients (13.82 percent) had associated ileal pouch inflammation (23 with symptoms requiring systemic treatment because of pouchitis; 10 patients had concomitant topical treatment). CONCLUSION: Symptomatic inflammation of the retained mucosa occurred in 32 (14.7 percent) patients. Nine (4.1 percent) patients had inflammation of the anal canal alone, and 23 (10.6 percent) had pouchitis in addition. The need for treatment occurred in 28 (12.9 percent) of the total ((2.3 percent) patients with anal canal inflammation and 23 (10.6 percent) with anal canal inflammation plus pouchitis).

Ileal pouch-anal anastomoses complications and function in 1005 patients.

BACKGROUND: Restorative proctocolectomy and ileal pouch-anal anastomosis (IPAA) has become an established surgery for patients with chronic ulcerative colitis and familial adenomatous polyposis. PURPOSE: The authors report the results of an 11-year experience of restorative proctocolectomy and IPAA at a tertiary referral center. METHODS: Chart review was performed for 1005 patients undergoing IPAA from 1983 through 1993. Preoperative histopathologic diagnoses were ulcerative colitis (n = 858), familial adenomatous polyposis (n = 62), indeterminate colitis (n = 75), and miscellaneous (n = 10). Information was obtained regarding patient demographics, type and duration of diseases, previous operations, and indications for surgery. Data were collected on surgical procedure and postoperative pathologic diagnosis. Early (within 30 days after surgery) and late complications were noted. Follow-up included an annual function and quality-of-life questionnaire, physical examination, and biopsies of the pouch and anal transitional zone. RESULTS: Of the 1005 patients (455 women), postoperative histopathologic diagnoses were as follows: ulcerative colitis (n = 812), familial adenomatous polyposis (n = 62), indeterminate colitis (n = 54), Crohn's disease (n = 67), and miscellaneous (n = 10). During a mean follow-up time of 35 months (range 1-125 months), histopathologic diagnoses were changed for 25 patients. The overall mortality rate was 1% (n = 10 patients, early = 4, late = 6); one death (0.1%) was related to pouch necrosis and sepsis. The overall morbidity rate was 62.7% (1218 complications in 630 patients; early, n = 27.5%; late, n = 50.5%). Septic complication and reoperation rates were 6.8% and 24%, respectively. The ileal pouch was removed in 34 patients (3.4%), and it is nonfunctional in 11 (1%). Functional results and quality of life were good to excellent in 93% of the patients with complete data (n = 645) and are similar for patients with ulcerative colitis, familial adenomatous polyposis, indeterminate colitis, and Crohn's disease. Patients who underwent operations from 1983 through 1988 have similar functional results and quality of life compared with patients who underwent operations after 1988. CONCLUSION: Restorative proctocolectomy with an IPAA is a safe procedure, with low mortality and major morbidity rates. Although total morbidity rate is appreciable, functional results generally are good and patient satisfaction is high.

Use of laparoscopic techniques in colorectal surgery. Preliminary study.

PURPOSE: This study evaluated the feasibility and safety of laparoscopic bowel surgery performed by colorectal surgeons not previously experienced in laparoscopic biliary or appendiceal surgery. METHODS: Thirty-two patients underwent ileocolic resection/anastomosis (n = 12), loop ileostomy (n = 7), colostomy (n = 4), ileostomy takedown/ileorectal anastomosis (n = 3), subtotal colectomy/ileorectal anastomosis (n = 2), sigmoid resection (n = 2), or other procedures (n = 2). No curative cancer surgery was undertaken. RESULTS: Time to first bowel movement was one to eight (median, four) days. Length of stay ranged from 4 to 11 (median, 6) days. There were no major complications seen in follow-up from 6 to 15 (median, 7) months after surgery. CONCLUSIONS: Large intestinal and distal ileal surgery using laparoscopic techniques, performed by surgeons with training only in laparoscopic intestinal surgery, is feasible and safe. Faster recovery and need for less postoperative analgesia in laparoscopic surgery compared with conventional surgery cannot be surmised from this study. A randomized study design is needed to evaluate many of the differences between conventional and laparoscopic intestinal surgery.

Endocavitary irradiation. An option in select patients with rectal cancer.

PURPOSE: Endocavitary irradiation delivers high-dose irradiation with limited penetration and is an established modality for the curative treatment of select tumors. The purpose of this study was to review the experience from our institution with endocavitary irradiation. METHODS: All patients with rectal cancer treated with endocavitary irradiation between 1973 and 1992 were studied. Collected data included: tumor size, tumor differentiation, distance from the anal verge, mean follow-up, recurrence, and other treatments used. RESULTS: One hundred ninety-nine patients received endocavitary irradiation, with 126 treated with curative intent. No significant differences were found between groups with recurrence and no recurrence when examining tumor size, differentiation, distance from the anal verge, or follow-up. With a mean time to recurrence of 16.1 (range, 1-56) months, 37/126 patients had a recurrence, and 89/126 had no recurrence. Ten recurrences were distant, and all patients died of the disease. Twenty-seven patients had local recurrence. Following additional treatments, 14 additional patients were rendered free of disease. CONCLUSION: Endocavitary irradiation initially rendered 71 percent (89/126) free of disease. With additional treatment 11 percent (14/126) were rendered free of disease. In the subgroup of patients followed more than five years, 68 percent had no evidence of disease at follow-up after endocavitary irradiation, and 91 percent had no evidence of disease with additional treatment. Tumor size, differentiation, morphology, and distance from the anal verge did not influence recurrence. Debulking or surgical excision before endocavitary irradiation did not increase recurrence. Diligent long-term follow-up and a liberal policy to biopsy suspicious areas may increase the salvage rate.

Incidence, risk factors, and treatment of dysplasia in the anal transitional zone after ileal pouch-anal anastomosis.

UNLABELLED: Preservation of the anal transitional zone (ATZ) after restorative proctocolectomy and stapled ileal pouch-anal anastomosis (IPAA) for ulcerative colitis is controversial. PURPOSE: To evaluate the incidence, risk factors, and treatment options for dysplasia and/or cancer after restorative proctocolectomy and stapled IPAA. METHODS: We reviewed the records of all 254 patients operated on for ulcerative colitis who had a restorative proctocolectomy, stapled IPAA, and annual postoperative biopsies of ATZ. Follow-up studies included an annual questionnaire and physical examination. RESULTS: During a follow-up of 2.3 +/- 1.4 (mean +/- standard deviation) years, low-grade dysplasia was found in eight patients (3.1 percent), 16 (median: range, 6-56) months after surgery. Repeated biopsies revealed dysplasia in only two of eight patients, and completion mucosectomy was performed. Dysplasia in ATZ was associated with a preoperative (P = 0.02) or postoperative (P = 0.04) pathologic diagnosis of ulcerative colitis with concurrent dysplasia or cancer. No association (P > 0.05) was found between dysplasia and the following: age, sex, preoperative length of disease, use of a double-stapled versus single-stapled technique, or anastomotic distance from the dentate line. CONCLUSIONS: Incidence of low-grade dysplasia in ATZ was low. Restorative proctocolectomy with total mucosectomy of the anal canal and handsewn IPAA is recommended for patients with preoperative diagnosis of ulcerative colitis and concurrent cancer or dysplasia. Frequent follow-up with biopsies is recommended for patients with incidental finding of cancer or high-grade dysplasia after restorative proctocolectomy and stapled IPAA with preservation of ATZ. For persistent or recurrent low-grade dysplasia, we recommend a completion mucosectomy.

Ulcerative colitis and coexisting colorectal cancer: recurrence rate after restorative proctocolectomy.

BACKGROUND: The association between mucosal ulcerative colitis (MUC) and adenocarcinoma is well established. METHODS: Records of patients who had undergone restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) from 1983 through 1992 were examined. Of these, 604 had MUC and 27 (4.3%) had MUC with coexisting cancer. Patients were surveyed annually for recurrent disease. Pouch function and quality of life were evaluated with a questionnaire and physical examination. RESULTS: The duration of disease was longer (p = 0.001) in patients with cancer (16.1 +/- 8.0 years) than in those without cancer (9.1 +/- 7.1 years), although the mean age at diagnosis of MUC was the same. Of the 27 patients, 20 had colon cancer and seven had rectal cancer. Multicentricity was found in seven (25.9%) patients. Using the TNM staging classification, 14 patients (51.8%) had stage 1 cancer, eight (29.6%) had stage 2, four (14.8%) had stage 3, and one (3.8%) had stage 4. The patient with stage 4 cancer died 5 months after surgery and was excluded from the follow-up analysis. During a mean follow-up time of 4.3 +/- 2.6 years, cancer recurred in two of the remaining 26 patients (7.7%). In one patient, a local recurrence was found 8 months after surgery, and distant metastases were found in the other patient 35 months after surgery. Both recurrences were in patients with colon cancer. Two of the 26 patients died; one death was related to cancer recurrence (3.8%). Pouch function is good to excellent in all surviving patients. CONCLUSIONS: Restorative proctocolectomy for patients with MUC and coexisting colorectal cancer can be performed with a favorable prognosis and function. It is appropriate for curative intent, given that an adequate margin without tumor is obtained.

The differential diagnosis and comorbidity of hidradenitis suppurativa and perianal Crohn's disease.

Over the last 8 years, 61 patients with hidradenitis suppurativa (HS) have been treated at this institution. Twenty-four have also had a diagnosis of Crohn's disease (38%). This dual pathology is examined in detail in this retrospective review. There were 11 males and 13 females with a mean age of 39 years (range 18 to 75 years). The Crohn's disease was ileal in 1 patient, ileocolic in 4, and affected the large bowel only in 19. The diagnosis of Crohn's disease predated that of HS by an average of 3.5 years. At the time of review, 22 patients had a stoma, 23 had undergone laparotomy and 17 had lost their rectum. Hidradenitis suppurativa occurred in the perineal or perianal area in all patients but involved other sites in 20 cases. Skin grafting had been done in 9 and local procedures in 19 patients. Granulomas were found in excised skin in 6 cases but this finding was not associated with a poor outcome. At a mean follow-up of 3.2 years from the most recent surgery for HS (range 1 to 11 years) 11 were asymptomatic for HS, 11 had symptoms and no follow up was available in 2. These data show that HS may coexist with Crohn's proctocolitis, complicating the diagnosis and management of patients in whom it occurs. An increased appreciation of the possibility is recommended.
