Seton management of complex anorectal fistulas in patients with Crohn's disease.

Anorectal fistulas associated with Crohns disease are difficult to manage, particularly when the rectum is diseased. Significant morbidity has been associated with both medical and surgical therapy. Although conventional therapy is acceptable in the management of simple fistulas in Crohns disease, these approaches often exacerbate rather than ameliorate problems in patients with complex fistulas. The authors report ten cases of complex fistulas in patients with Crohns disease managed with their technique of long-term, indwelling setons. These setons are placed through the fistula tract and tied loosely to maintain the patency of the fistula without cutting through the sphincters. At the time of insertion, although abscesses are incised and drained, no attempt is made to divide the superficial tissues or sphincter overlying the fistulous tract. The patients ranged in age from 23 to 81 years and had a history of Crohns disease for 1 to 20 years. All cases resulted in excellent palliation. No patient required a proximal colostomy. These patients have been followed for four months to seven years. Despite severe proctitis in six of these patients at the initial operation, no patient has required a proctectomy. The authors believe this technique achieves adequate palliation and should be employed as the procedure of choice in patients with complex anal fistulas associated with Crohns disease.

Complications of colostomies

One hundred twenty-six patients underwent 130 end colostomies, 44 for benign and 86 for malignant disease, and were followed for an average of 35 months. The left or sigmoid colon was used in 99 and the transverse colon in 31. Stomas were made electively in 98 patients and urgently in 32. Seventy-six stomas were brought out through the incision and 54 from separate sites. There were 69 complications in 55 patients (44 percent) including 11 strictures, 9 wound infections, 14 hernias, 9 small-bowel obstructions, 4 prolapses, 2 abscesses, 1 peristomal fistula, 17 skin erosions, and 2 poor stoma locations. Fifteen complications required reoperation. Five of these procedures included stoma revision. Total numbers of complications were not related to the stoma site, the disease process, the urgency of the procedure, or the segment of colon used. Wound infections, however, were increased in urgently made stomas. The incidence of hernia was equivalent in stomas brought out through the incision or at a separate site. Forty-one patients (30 percent) had 43 colostomies closed an average of 3.5 months after creation. Thirteen patients had 14 complications-5 wound infections, 6 hernias, 2 small-bowel obstructions, and 1 rectovaginal fistula. One patient died. Four patients required reoperation. There were no anastomotic leaks. Complications were equivalent in Hartmann closures and transverse colostomy closures. Complications were similar in stomas created for cancer and those created for diverticular disease.One hundred twenty-six patients underwent 130 end colostomies, 44 for benign and 86 for malignant disease, and were followed for an average of 35 months.

Use of ureteral catheters in colonic and rectal surgery

Injury to the ureters is a serious complication of colonic and rectal surgery. The experience of the authors with routine use of ureteral catheters to minimize this complication is reviewed. It was found that there are minimal complications associated with their use. Injuries to the ureters were not completely avoided. However, unrecognized injuries (except ischemia) did not occur.

Delorme's procedure for complete rectal prolapse in severely debilitated patients

PURPOSE: This study was designed to assess the results of a minimally invasive surgical procedure for the correction of complete rectal prolapse in a poor surgical risk group. METHODS: Over a ten-year period, 40 patients underwent 41 Delorme operations when advanced age and/or poor overall health mitigated against an abdominal approach. Mean age was 82 (range, 30–100) years. Eighty-eight percent were females. Surgery was performed in the prone jackknife position utilizing intravenous sedation and local anesthesia. RESULTS: Follow-up ranges from 1 year to 2 years (mean, 47 months). There have been 9 recurrences in 8 patients (22 percent). Mean time to recurrence was 13 months (range, 1 month to 6 years). One death occurred in an 81-year-old patient within 24 hours of surgery from cardiopulmonary arrest. Minor complications occurred in 25 percent of patients. CONCLUSION: Satisfactory prolapse repair was safely performed in 78 percent of this high-risk group. Pitfalls in performing this procedure relate primarily to associated perineal and colonic conditions. Most prominent among these conditions are weak or absent anal sphincter tone, perineal descent, and previous sphincter injury. Extensive diverticular disease may prohibit effective and complete proximal mucosectomy. An inadequate mucosectomy sets the stage for early recurrence of prolapse.

Is preoperative computerized tomography useful in assessing patients with colorectal carcinoma

PURPOSE: Controversy exists over the appropriate preoperative evaluation of colorectal cancer patients. Most surgeons agree that basic laboratory studies are indicated. Computerized tomography of the abdomen and pelvis has been used in our practice to augment the preoperative evaluation of these patients. METHODS: One hundred fifty-eight consecutive patients with primary colorectal carcinoma underwent computerized tomography (CT) of the abdomen as part of their preoperative evaluation. Their medical records were retrospectively reviewed. RESULTS: In 88 patients, 120 findings present on CT were otherwise unknown. Of these, 35 percent were clinically significant in that they allowed the surgeon to alter the proposed operative procedure or added additional technical information for consideration preoperatively. Findings include liver metastasis (26), atrophic kidney (3), and abdominal wall or contiguous organ invasion (11). In addition, two other solid organ carcinomas were detected. In the remaining 70 patients, CT contributed no additional pertinent information about the patient prior to this initial operative procedure. CONCLUSIONS: CT aids in the preoperative evaluation of individuals with colorectal carcinoma. It provides important clinical information that is useful to the surgeon planning the procedure. Additionally, CT permits the patient and his family to be aware of their overall status and to subsequent treatment options. Computerized tomography eliminates the need for preoperative intravenous pyelogram, improves the preoperative staging for metastatic disease, and provides a baseline for comparison during the postoperative follow-up period should recurrence be suspected or adjuvant therapy be planned.

Five year survival in patients with carcinoma of the rectum treated by electrocoagulation

Sixty-eight patients with rectal cancer treated by electrocoagulation are reviewed. All were followed up for a minimum of 5 years. The survival rate in patients with small exophytic cancers is greater than 70 percent. However, the recurrence rate after electrocoagulation is 40 percent. Electrocoagulation offers an alternative for the primary treatment of rectal cancer, particularly in older patients with small lesions.

The role of nasointestinal intubation in elective colonic surgery

On hundred thirty-eight consecutive patients undergoing elective colonic resections were treated prospectively and randomly with either a long intestinal (Cantor) tube preoperatively, a nasogastric tube placed intraoperatively, or no gastrointestinal tube at all. Patients were evaluated for length of hospital stay, duration of postoperative ileus, adequacy of intraoperative intestinal decompression, gastric dilatation, and operative complications. No significant difference could be seen in the tubed or no-tube group.

Electrogalvanic stimulation in the treatment of levator syndrome.

The records of 102 patients with levator syndromes were reviewed. All had failed trials of conservative management prior to treatments with electrogalvanic stimulation. The symptoms of 12 patients were subsequently found not to be due to levator syndrome. Of 90 patients with correct diagnoses, 77 percent were relieved or improved after courses of electrogalvanic stimulation, a valuable adjunct to the management of this frustrating condition.

Anastomotic recurrences after low anterior resection

A retrospective study was done comparing the rates of local recurrence in cancer of the rectum treated by low anterior resection using the stapling device or hand-sewn. It was found that there was no increase in recurrences when the stapler was used, even though lower lesions were treated.

Is the abdominal repair of rectal prolapse safer than perineal repair in the highest risk patients? An NSQIP analysis.

BACKGROUND: Although the perineal approach in the surgical management of rectal prolapse has a higher recurrence, it is the accepted approach for higher-risk patients because of its lower morbidity. OBJECTIVE: The aim of this study was to determine outcomes of abdominal versus perineal approaches to rectal prolapse repair. DESIGN SETTINGS: A retrospective study was performed comparing outcomes of patients undergoing different types of surgical approaches (open abdominal, laparoscopic, perineal) for rectal prolapse. PATIENTS: The American College of Surgeons National Surgical Quality Improvement Participant User Data Files (2008–2009) were queried for patients undergoing adult, elective procedures for rectal prolapse. MAIN OUTCOME MEASURES: Univariate analysis and multivariate logistic regression were performed to look at age, ASA classification, procedure type, and resultant mortality rate. RESULTS: One thousand four hundred sixty-nine patients meeting our criteria were identified. Older patients (age>80) and higher-risk patients (ASA classifications 3and 4) were significantly associated with the selection of the perineal approach. The overall mortality rate was 0.5%. The mortality rate for all perineal procedures was 0.9% in comparison with 0.13% for all abdominal operations (p = 0.033). The mortality rate for the highest-risk groups (ASA 3 and 4) for perineal procedures was 1.3% in comparison with 0.35% in the abdominal procedure group; the relative risk for mortality was 4 times greater in the perineal procedure group than in the abdominal procedure group. LIMITATIONS: The retrospective design and standardized outcomes measured use administrative-level data and prevent the assessment of procedure-specific outcomes. CONCLUSIONS: Hospital mortality for the surgical repair of rectal prolapse is uncommon. The decision to choose the abdominal approach for the repair of rectal prolapse may not be as prohibitive as previously thought for higher-risk patients. Because of the broad range of functionality within each ASA classification, the operation offered should always be individualized, and patient selection is the most important factor.
