Use of "house" advancement flap in anorectal diseases.

BACKGROUND: A retrospective review of 28 patients who had "house flap" anoplasty was carried out to evaluate the therapeutic effectiveness of the procedure. METHODS: House flap anoplasty was performed at Istanbul University Cerrahpasa Medical School, General Surgery Department, in 28 patients over 4 years. Indications were chronic anal fissure, anal stenosis, high transsphincteric fistula, low rectovaginal fistula, anal neoplasia, and obstetric third-degree perineal tear and incontinence. After rectangular excision of the anal or perianal lesion, the "walls" and "roof" of the house flap were incised to the depth of ischiorectal fat. The "base" of this house-shaped flap was then fixed to the top of the excised area. RESULTS: Median postoperative hospital stay was 4.86 (range = 2-12) days. Postoperative complications included three patients with minimal wound dehiscence and one with rectovaginal fistula recurrence. At a median follow-up of 26.4 (range = 1-46) months, excluding the patient with recurrence, all patients were satisfied with house flap anoplasty. CONCLUSION: House advancement flap anoplasty is a relatively simple procedure, combining the beneficial features of rectangular flaps and V-Y plasties. It can be used in nearly all types of anoderm deficiencies with a high rate of success and patient satisfaction.

Primary umbilical adenocarcinoma: case report and review of the literature.

Primary adenocarcinoma arising at the umbilicus is a very rare condition. The umbilicus has been found to show a wide variety of tumors and is predisposed to metastases from visceral tumors because of its relationships and generous vascular and embryologic connections. Herein, we describe a case of a primary umbilical adenocarcinoma with short time survival related to local recurrence and multiple hepatic metastases 6 months after her surgical treatment.

Passage of "colonic cast" after colorectal surgery: report of four cases and review of the literature.

Anal passage of a full-thickness infarcted colonic segment (so-called "cast") not accompanied by any features of acute peritonitis is a very rare occurrence and may be the main advertising manifestation of acute colonic ischemia. Most of the reported cases of acute colonic ischemia are secondary to abdominal aortic aneurysms and ensuing inferior mesenteric artery thrombosis or to the repair of these aneurysms. The preceding events causing ischemia in other cases are Hartmann reversal, rectal resection and colonic J-pouch construction, and acute pancreatitis. In this article we present our experience on four cases of colonic cast passage, all of which developed subsequent to colorectal resection. Three of these casts are supposed to be mucosal and one is transmural. Generally, surgery is the rule and consists of the resection of the concerned ischemic segment. Every clinician should be aware of this form of presentation of bowel ischemia, not only following aneurysm surgery but also in the postoperative course of colorectal surgery.

Enteroliths developed in a chronically obstructed afferent loop coexisting with gastric remnant carcinoma: Case report and review of the literature.

A case of gastric remnant carcinoma coexisting with a chronic afferent loop syndrome harboring multiple enteroliths in a grossly dilated and elongated afferent loop is presented herein. The patient had undergone a Polya type antecolic Billroth II reconstruction for a stenosing duodenal ulcer 40 years previously. A concise review of the relevant literature is also presented.

Internal herniation concurrent with ileosigmoid knotting or sigmoid volvulus: Presentation of 12 patients.

BACKGROUND: Internal herniation concurrent with ileosigmoid knotting or sigmoid volvulus is an unusual and complex form of closed-loop obstruction that may result in a fatal outcome unless treated timely and properly. The aim of this article was to review our experience with this condition, with emphasis on the etiopathogenesis, clinicopathologic features, and treatment options. METHODS: We conducted a retrospective analysis of medical records of 12 patients treated at 2 university hospitals over a period of 30 years between 1970 and 2000. RESULTS: In this series, the internal herniation resulted in ileosigmoid knotting in 8 cases, whereas it was concomitant with sigmoid volvulus in 4 cases. The types of internal herniation were identified as transmesenteric through the Treves field in 8 patients and as transomental, intersigmoidal, pericecal, and around omphalomesenteric fibrous cord in 1 patient each. The rate of gangrenous bowel was 100%. En bloc resection for combined gangrene of small bowel and large bowel was the treatment of choice in 7 patients, of whom 5 underwent the Hartmann's procedure and 2 underwent primary sigmoidectomy-anastomosis in addition to primary enterectomy-anastomosis. Primary sigmoidectomy-anastomosis and Mikulicz's procedure were performed in 2 patients for gangrenous sigmoid colon only. Three patients underwent primary enterectomy-anastomosis for gangrenous small bowel only. The morbidity rates and the mortality rate were both 33.3%. The mean length of hospital stay following emergency operations was 11.2 days. CONCLUSIONS: In particular, surgeons who are from developing countries that form the world's "volvulus belt" should be aware of this entity's features and be ready to perform an appropriately selected surgical option for a given patient to accomplish the optimal clinical outcome.
