Anastomotic configuration does not affect recurrence of Crohn's disease after ileocolonic resection.

The influence of anastomotic configuration on recurrence of symptomatic Crohn's disease has been assessed in a sequential study of patients undergoing resection of ileal Crohn's disease. Between 1972 and 1991 92 patients had 102 ileocolonic anastomoses constructed after resection of intestinal Crohn's disease. The configuration of the ileocolonic anastomosis was either end to side (ES, n = 68) or side to side (SS, n = 34). The majority of patients in both groups were female and both groups were similar for duration of Crohn's disease at resection, steroid therapy, previous number of intestinal resections, indication for surgery and length of ileum resected at operation. No anastomotic leak occurred in either group. A total of 39 patients developed symptomatic recurrent Crohn's disease including 31 (46%) in the ES group and 8 (24%) in the SS group. This difference was related to the length of follow-up, the annual rate of symptomatic recurrence was almost identical for both end to side (0.066) and side to side (0.052) anastomoses.

A case of squamous cell carcinoma complicating hidradenitis suppurativa.

A case of extensive squamous cell carcinoma arising in widespread perianal and inguinal hidradenitis suppurativa is used to illustrate the pathological features which influence management. The surgical pathology, with wide extension along subcutaneous sinuses, frequently leads to the view that it is incurable. A planned surgical approach, using both immediate frozen section and delayed paraffin histology to assess clearance margins allowed complete surgical excision in two stages. Colostomy is not a necessary part of management and healing by granulation is an acceptable alternative to extensive reconstruction procedures. Radiotherapy and chemotherapy, sometimes used in palliation mode, are not likely to be beneficial.

Ileostomy polyps, adenomas, and adenocarcinomas.

Ileostomy polyps are uncommon and poorly described. The aim of this study was to undertake a retrospective clinicopathological review of ileostomy polyps. Seven patients with 60 polyps arising on ileostomies performed for ulcerative colitis were studied. The histopathological evaluation of archival ileostomy biopsy specimens, polypectomy or excision specimens, and clinical review of patient records was undertaken. Fifty of 60 polyps were inflammatory cap polyps and six further polyps were composed of granulation tissue only. They occurred anywhere on the stoma at any time after ileostomy construction and were strongly associated with overt stomal prolapse. Four neoplastic polyps were identified in two patients 27-36 years after ileostomy construction; all occurred at the mucocutaneous junction. One patient presented with a 2 cm polypoid invasive adenocarcinoma while in the second a 1.7 cm polypoid mucinous adenocarcinoma and a 0.7 cm ileal tubular adenoma with high grade dysplasia occurred at the site of excision of a cap polyp showing focal low grade adenomatous dysplasia six years previously. Neoplastic and non-neoplastic polyps could not be differentiated clinically. It was found that most ileostomy polyps are inflammatory cap polyps associated with stomal prolapse. Less common are polypoid adenomas or adenocarcinomas arising at the mucocutaneous anastomosis > 20 years after ileostomy construction. To prevent ileostomy carcinoma it is recommended that a biopsy of all polyps at the mucocutaneous anastomosis and of any non-prolapse associated polyps elsewhere on the stoma occurring > 15 years after ileostomy construction is done.

Parastomal pyoderma gangrenosum in inflammatory bowel disease.

PURPOSE: Parastomal pyoderma gangrenosum is uncommon and its association with inflammatory bowel disease is unclear. This is a review of five patients with parastomal pyoderma gangrenosum. METHODS: A retrospective review of five patients with ulcerative colitis (two patients) or Crohn's disease (three patients) who have been seen in one surgical unit was conducted. RESULTS: All patients were females and each presented within nine months of abdominal surgery and stoma construction. All had active proctitis (n = 3) or perianal Crohn's disease (n = 2). Both patients with perianal Crohn's disease had a mild clinical course with healing of parastomal pyoderma gangrenosum when treated with steroids with and without low-dose cyclosporin A. They both had curettage of the perineal wound as well. In the remaining three patients with active proctitis, the parastomal lesions failed to resolve despite high-dose systemic steroids. By contrast, the parastomal pyoderma gangrenosum healed promptly in two of these patients following proctectomy for active proctitis. CONCLUSION: The variable clinical outcome of parastomal pyoderma gangrenosum may be related to the activity of the underlying inflammatory bowel disease or possibly to low-grade perineal sepsis.

Timing of ileocolonic resection for symptomatic Crohn's disease--the patient's view.

Eighty patients were asked if they would have preferred their ileocolonic resection and anastomosis for Crohn's disease, to have been carried out sooner, later or at the same time as it was done. Seventy of the patients replied (88%). No patient would have preferred their operation to have been later, while 74% thought it should have been earlier. A preferred operation time was given for 69 resections, between 0 months--that is, at the same time--and 15 years earlier. The median preferred operation time was 12 months earlier (95% confidence intervals 18 months earlier to 7 months earlier). The remaining 18 patients were satisfied with the timing of their operation. Reasons given for earlier surgery in 58 resections included the severity of Crohn's symptoms preoperatively (97%), the ability to eat normally after resection (86%), feeling of well being after the resection (62%), and abolishing the need for drugs (43%). Patients preferring an earlier operation time were less likely to have had a previous resection (13/58) than patients in the 'same time' group (10/21, chi 2 = 4.746; p < 0.05).

Bowel diversion should be used with caution in stenosing anal Crohn's disease.

Proximal diversion has commonly been used for severe perianal Crohn's disease in an attempt to relieve local symptoms, whether the primary intestinal disease is in the colon or small bowel. Two patients are presented in whom diversion led to severe symptomatic disease in the previously normal defunctioned bowel. In each case the development of colonic disease was associated with increasing anal stenosis leading to retention of purulent fluid within the bowel lumen. Faecal stream diversion should be used with caution in stenosing anal Crohn's disease.

Safe margins in the excision of primary cutaneous melanoma.

A group of 434 patients treated for primary cutaneous melanoma over an 18-year period by a policy of selective excision margins based on clinical estimation of tumour thickness was studied prospectively. Clinical assessments of tumour as impalpable, palpable but not overtly nodular, and nodular correspond to thicknesses of < or = 0.75, 0.76-1.49 and > or = 1.50 mm respectively. From 1971 to 1987, 330 patients were treated with excision margins of 1, 2 and 3-5 cm based on these respective ranges. During 1988 and 1989, 104 patients were treated after reduction of the maximum width of excision to 2 cm. The overall local recurrence rate was 11 of 434 patients (2.5 per cent), with no recurrence in melanoma < or = 0.75 mm thick and no increase in the local recurrence rate after reduction of the maximum margin from 3 to 2 cm. A policy of 2-cm clearance for palpable and nodular melanoma and 1 cm for impalpable lesions is recommended. Any further reduction must be tested prospectively.

Management of malignant melanoma of the head and neck.

A total of 91 patients with melanoma of the head and neck treated between 1973 and 1991 were studied prospectively with regard to prognostic features, treatment and outcome. Other than Breslow thickness, the only important prognostic feature was the less aggressive nature of lentigo maligna melanoma. A policy of selective excision margins, 1 cm for impalpable and 2 cm for palpable lesions, was found to be safe, although preliminary biopsy should be used if there is diagnostic uncertainty or where the expected extent of surgery entails a mutilating procedure. Local recurrence rates were not affected by the method of wound closure, which should be determined by the best functional and cosmetic outcome. These results support the trend against prophylactic neck dissection. Such dissection, when indicated for lesions of the face, pinna, anterior scalp and parotid area, should routinely include superficial parotidectomy. Uncontrolled symptomatic loco-regional recurrence is an uncommon complication that may occur despite radical primary surgery. The role of preoperative radiotherapy for high-risk melanoma in this situation warrants investigation.

Granulomatous hidradenitis suppurativa and cutaneous Crohn's disease.

Three patients with concurrent hidradenitis suppurativa and Crohn's disease are presented. The notable histological feature in each hidradenitis resection was the presence of numerous discrete epithelioid granulomas in areas of non-inflamed dermis. The purpose of the study was to determine the incidence of epithelioid granulomas in 101 hidradenitis patients and their significance in relation to systemic granulomatous disease. Discrete epithelioid granulomas were identified in 8% of the resections (10 patients). One patient had Crohn's disease and one other pulmonary sarcoidosis. Seven patients with granulomatous hidradenitis neither had nor developed any other disease during the 3-year follow-up period. Clinical review identified a further two patients with Crohn's disease but associated with non-granulomatous changes in the skin resections. Foreign body type granulomas were identified in 25% of the resections adjacent to ruptured hair follicles, sinus tracts or nearby degenerate sweat glands. The study shows that, although foreign body type granulomas are a common finding in hidradenitis, the presence of discrete epithelioid granulomas in the dermis away from the site of active inflammation is unusual and should alert the pathologist to the possibility of systemic granulomatous disease such as Crohn's disease or sarcoidosis.

Multiple fibroadenomas of the breast: a problem of uncertain incidence and management.

A case is presented of multiple fibroadenomas of the breasts in a young Caucasian woman followed over a period of 10 years. A total of 22 individual lesions have been identified. Review of the literature gives little guidance regarding incidence, natural history and management of this condition. It is proposed that a register be set up to obtain basic data on this rare condition. The authors would be willing to collate cases submitted to such a register.

Is immediate postmastectomy reconstruction safe in the long-term?

A prospective case-control study of 81 patients has been carried out over 10 years comparing mastectomy with immediate reconstruction to mastectomy alone. The patients were matched for age (within 5 years), TNM stage, pathologic nodal status and operative procedure. After complete 10-year follow-up we have failed to demonstrate any long term difference in tumour behaviour. We conclude that immediate reconstruction is widely applicable and technically feasible without any long term effect on the development of local recurrence or metastatic disease.

Complications of rectus abdominis myocutaneous flaps in breast surgery.

One-hundred-and-twenty-two rectus abdominis myocutaneous flaps used for reconstruction, post mastectomy (106) and after salvage surgery (16), were reviewed. The minimum period of follow up was 24 months. Simple vertical flaps were raised in 88 patients; in addition seven Drevers, four trans-umbilical, 19 lower transverse and four combined (vertical and transverse flaps) were raised. Early complications (within 2 weeks of surgery) were seen in 30% (37/122) patients. Late complications occurred in 5% of patients (6/122) and 8% had both early and late complications. Flap necrosis was seen in 25% (21/122) of patients. This comprised complete flap loss in two patients. Partial skin and fat necrosis was observed in 14 patients and partial skin loss only in 15. In the group with simple vertical flaps the incidence of partial flap necrosis was 12.5%. Late complications included incisional hernia in 5% of patients. Reoperation for complications were required in 18% of patients. We conclude that while minor morbidity is common with rectus flaps, major complications are few. The more important considerations relate to cigarette smoking and overuse of the peripheral segment of the transverse rectus abdominis flap. While the transverse flaps have now largely replaced other breast flaps, in our practice vertical and higher transverse flaps were useful alternatives. Lessons learned during the development of these flaps have led to greatly improved results in the latter part of the series and it is regarded as a versatile and useful flap in this situation.
