Stoma complications: the Cook County Hospital experience.

PURPOSE: A retrospective analysis of enteric stomas performed at Cook County Hospital was undertaken to evaluate stoma complications per stoma type and configuration and operating service. In addition, we attempted to identify factors predictive of increased enteric stoma complications. METHODS: From 1976 to 1995, data cards on 1,616 patients with stomas were compiled by Cook County Hospital enteric stomal therapists. Data card information included age, gender, weight, early and late stoma complications, emergency status, operating service, type and configuration of the stoma, and whether the patient was seen preoperatively by an enteric stomal therapist. Data were then analyzed using a logistic regression model to identify those variables that influenced the rate of complications. RESULTS: There were 553 (34 percent) patients with complications. Among the total complications, 448 (28 percent) occurred early (<1 month postoperative), and 105 (6 percent) occurred late (>1 month). The most common early complications were skin irritation (12 percent), pain associated with poor stoma location (7 percent), and partial necrosis (5 percent). The most common late complications were skin irritation (6 percent), prolapse (2 percent), and stenosis (2 percent). The enteric stoma with the most complications was the loop ileostomy (75 percent). The enteric stoma with the least complications was the end transverse colostomy (6 percent). The general surgery service had the most complications (47 percent), followed by gynecology (44 percent), surgical oncology (37 percent), colorectal (32 percent), pediatric surgery (29 percent), and trauma (25 percent). Age, operating service, enteric stoma type and configuration, and preoperative enteric stomal therapist marking were found to be variables that influenced stoma complications. CONCLUSIONS: Complications from enteric stoma construction are common. Preoperative enteric stoma site marking, especially in older patients, and avoiding the ileostomy, particularly in the loop configuration, can help minimize complications.

Giant pseudopolyps presenting as colocolic intussusception in Crohn's colitis.

Bowel obstruction is a well-known complication of Crohn's disease and is usually a result of stricture formation. Intussusception due to giant pseudopolyps is a rare form of bowel obstruction even in Crohn's disease. These giant pseudopolyps rarely regress with medical management alone and often require surgical resection.

Does preoperative stoma marking and education by the enterostomal therapist affect outcome?

INTRODUCTION: It is generally accepted that preoperative patient education and skin marking for a stoma location are important in avoiding stoma complications. At our institution, enterostomal therapists are available to educate and mark patients before their surgery. However, for various reasons, not all patients who had an elective stoma created, had preoperative skin marking or instructions on stoma care. Our registry of patients provided us with a means of comparing patients who have undergone an elective stoma with (Group I) and without (Group II) preoperative marking and education. METHODS: Our stoma registry consisting of 1,790 patients was retrospectively reviewed from 1978 to 1996 to assess all patients who underwent elective stoma construction. Patients included for review had a total of 593 elective stomas. All patients with stomas are followed by the enterostomal therapists postoperatively and, therefore, were evaluated for both early and late complications. Early complications were defined as any adverse event occurring within 30 days of surgery and late complications as those occurring 30 days after surgery. RESULTS: Our enterostomal therapists preoperatively evaluated 292 of the 593 patients planned for possible stoma creation. This included careful marking of the stoma site by having the patients lie down, sit, and stand and locating a stable flat area on the abdomen, taking into account the belt line and any abnormal skin creases or deformities. Patients were instructed on stoma appearance with a model and given basic stoma care instructions. In Group I, there were 95 (32.5 percent) complications (68 (23.3 percent) occurred early and 27 (9.25 percent) occurred late). There were 301 patients who did not receive preoperative evaluation (Group II). In this second group, 131 (43.5 percent) complications were found, (95 (31.6 percent) occurred early and 36 (12 percent) occurred late). The difference in total number of complications between groups was determined to be statistically significant, with a P value of <0.0075, as was the difference in early complications, with a P value of <0.03. The difference in late complications is not significant, with a P value of <0.34. CONCLUSIONS: These results confirm that preoperative evaluation by an enterostomal therapist, marking of the skin site, and providing patient education reduce adverse outcomes. All elective procedures that may result in stoma formation should, therefore, be assessed and marked preoperatively. Patients, likewise, should be informed and taught to care for their forthcoming stomas preoperatively and postoperatively.

The difficult perineal wound.

The postsurgical perineal wound may be difficult to manage. It is associated with a high incidence of complications, including infections, delayed healing, persistent sinuses, and fistulas. Careful preparation, consideration of established risk factors, and careful attention to surgical technique are essential for maintaining a good outcome.

Enterostomal complications: are emergently created enterostomas at greater risk?

It is not unusual for surgeons to have to construct a enterostoma during an emergency abdominal operation. The enterostomal complications, often overlooked, can be serious for the patient. There are many factors relating to stoma complications. The purpose of this paper is to determine whether the emergency status of an operation is an independent risk. Over a 19-year period from 1976 to 1995, there were 1758 enterostomas constructed at our institution. Fifty-nine per cent were for emergent situations, defined as any operation performed for peritonitis, obstructions, or massive hemorrhage. The data pertaining to complications was compiled by the enterostomal therapist and prospectively recorded into an institutional database. Complications were characterized as skin problems, parastomal problems (infection, separation), retraction, stenosis, necrosis, prolapse, and herniation. There were 624 (35%) patients with recorded complications. It was not uncommon for a patient to have more than one complication. There were 500 (55%) skin problems, 111 (12%) parastomal problems, 104 (11%) retractions, 33 (4%) stenoses, 112 (12%) necroses, 28 (3%) prolapses, and 19 (3%) enterostomas herniated. Overall, there were 1044 emergently created enterostomas, and we found that 356 (34%) patients had a complication. The most common indications for emergency laparotomies were abdominal gunshot wounds (40%), bowel obstruction (20%), bowel perforation other than by gunshot or stab wound (15%), and diverticulitis (8%). Among the nonemergently created enterostomas (714), there were 268 (37%) with complications (P = 0.015). Our findings suggest that emergently created enterostomas are not at greater risk for complications, except for the ileostomy. Although further analysis of this particular subset must be undertaken, the technical intricacies of an ileostomy, including preoperative marking of the site, might have an important role.

Abdominal actinomycosis.

PURPOSE: Actinomyces israelii are normal inhabitants in the oral cavity and upper intestinal tract of humans. They rarely cause disease and are seldom reported as pathogens. As a pathogen it causes fistulas, sinuses, and may appear as an abdominal mass and/or abscess. The abdominal mass can masquerade as a malignant process that is very difficult to differentiate, often requiring surgical intervention with resection. Because of difficulty in making a preoperative diagnosis, we undertook this review to determine if all patients require surgical intervention and whether other adjunctive modalities may improve preoperative diagnosis. METHODS: We report two patients with abdominal actinomycosis, one affecting the sigmoid colon and the other the retroperitoneum, iliac crest region. Both simulated a malignant process and required operations for diagnosis and treatment. RESULTS: As reported, actinomycotic abdominal masses and strictures can be treated by penicillin alone. Long-term medical treatment seems to be very successful and avoids surgical resection. The difficulty is obtaining a definitive diagnosis. CONCLUSION: The computed tomographic scan is the most helpful diagnostic modality. Appearance of abdominal actinomycosis is usually a contrast enhancing multicystic lesion as was found in these two patients. Needle aspiration cytology can be fairly accurate in obtaining the diagnosis and is recommended for suspicious lesions.

Island flap anoplasty for treatment of transsphincteric fistula-in-ano.

BACKGROUND: Treatment of fistula-in-ano often replaces one problem, risk of persistent anal sepsis, with another, either incontinence after fistulotomy or mucosal ectropion after rectal flap advancement. A new technique for treatment of transsphincteric fistulas is described that could eliminate risk of both complications. TECHNIQUE: Island flap anoplasty, previously used in management of anal strictures or ectropion, is modified to treat transsphincteric fistulas. RESULTS: The operation has been performed in 11 patients, 3 of whom had Crohn's disease. Follow-up varied from one to ten months. Early recurrences have occurred in three patients, two with Crohn's disease and one without. Remaining patients have done well. CONCLUSION: This procedure is technically easy to perform and appears to cure transsphincteric fistulas while preserving anal sphincter. In the event of persistence of fistula, other operative options are not eliminated by this procedure. We feel that further experience and longer follow-up is needed to define precise indications for this procedure and to determine if continence is improved more so than with standard fistulotomy.

A new method of creating an arteriovenous graft access.

Since the initial description of the radial arteriovenous (AV) shunt, hemodialysis has played a primary role in the survival of patients with chronic renal failure. However, it is not unusual to be confronted with patients on chronic hemodialysis who have exhausted all superficial venous access sites. We describe a technique using the deep veins of the arms the outflow system during AV graft construction. By anastomosing the venous limb of the graft to the larger of the two brachial veins, we have been able to give patients AV access when the superficial veins have been exhausted. We have performed this technique with good success in 12 patients. Further experience and longer follow-up are needed.
