The history of Crohn's disease.

Although it is likely that cases of what we know as granulomatous inflammatory bowel disease (Crohn's disease) may have been recorded as early as 1769, this illness is basically a disease of the 20th century. This historical review traces the development of our understanding of the disease and the evolution of its operative management.

The quality of early-stage breast cancer care.

OBJECTIVE: To assess whether recent practice has improved, the authors created detailed, evidence-based guidelines and assessed the quality of early-stage breast cancer care at four hospitals in the metropolitan New York area. SUMMARY BACKGROUND DATA: Adjuvant treatments for early-stage breast cancer have been shown to improve health and longevity. However, reports from the 1980s showed marked underuse of these therapies. METHODS: All 723 women with early-stage breast cancer who had a definitive surgical procedure at four participating hospitals in the Mount Sinai-NYU Health System between April 1994 and August 1996 were included. Inpatient and outpatient records were abstracted. RESULTS: Fifty-nine percent of women underwent breast-conserving surgery, of whom 81% received radiation therapy. Hospital-specific radiation therapy rates varied from 69% to 87%. Seventy-eight percent of women with stage 1B or greater cancer received systemic treatment, with hospital-specific rates varying from 71% to 86%. Between 18% and 33% of women who could have benefited from local or systemic adjuvant treatments did not receive them. The risk of not getting a beneficial adjuvant treatment varied more than twofold by the hospital where the breast cancer surgery was performed. CONCLUSIONS: The hospital where breast cancer surgery is performed is associated with the likelihood that women receive effective local and systemic adjuvant treatments. Surgeons and members of hospital quality improvement programs should encourage multidisciplinary approaches to breast cancer care.

The history of surgery for Crohn's disease at The Mount Sinai Hospital.

Almost certainly, the physicians and surgeons of The Mount Sinai Hospital cared for patients with inflammatory bowel disease prior to 1932. However, the accepted beginning of the surgery of granulomatous inflammatory bowel disease (IBD) and Crohn's disease (CD) at our institution occurred when the landmark paper by Crohn, Ginzburg, and Oppenheimer was published in 1932. As a major referral center for patients with both medical and surgical complications of IBD, the surgical service has had a long and abiding interest in the disease. This review highlights the major contributions of our staff to the management of this illness over the past 67 years. Despite major innovations in both medical and surgical management of patients with Crohn's disease, individuals suffering from this condition are ideally managed by a multidisciplinary team.

Intussusception in adults: institutional review.

BACKGROUND: Intestinal intussusception in the adult is a rare entity that differs greatly in etiology from its pediatric counterpart. Controversy remains regarding the optimal management of this problem in the adult patient. The purpose of this study was to determine the cause(s) of intussusception and to determine the role of intestinal reduction in the management of intussusception in adults. STUDY DESIGN: A retrospective review performed at The Mount Sinai Medical Center identified 27 patients, 16 years and older, with a diagnosis of intestinal intussusception. Data related to presentation, diagnosis, treatment, and pathology were analyzed. RESULTS: There were 13 males and 14 females. The median age of the group was 52 years with a range of 16 to 90 years. Abdominal pain was the most common presenting complaint. A preoperative diagnosis was suspected in 11 of 27 patients (40%). There were 22 small bowel lesions and 5 colonic lesions. A pathologic cause was identified in 85% of patients with 8 of 22 (36%) small bowel and 4 of 5 (80%) of large bowel lesions being malignant. All small bowel cancers represented metastatic disease and all large bowel malignancies were primary adenocarcinomas. The median age of patients with malignant disease was 60 years; it was 44 years for those with benign disease. Operative treatment consisted of resection alone in 58% of patients and resection after reduction in 42%. Three patients were treated nonoperatively. CONCLUSIONS: Our data support a selective approach to the operative treatment of intussusception in adults. Colonic lesions should not be reduced before resection because they most likely represent a primary adenocarcinoma. Small bowel intussusception should be reduced only in patients in whom a benign diagnosis has been made preoperatively or in patients in whom resection may result in short gut syndrome.

Complications requiring reoperation following pancreatectomy.

CONCLUSIONS: In this series, the overall reoperative rate following pancreatic surgery is 9%. Complications following pancreatectomy that require reoperation fall into four categories: hemorrhage, infectious, delayed gastric emptying, and anastomotic leak. A delay in the management of these types of complications can be fatal. BACKGROUND: Despite the improvement in the morbidity and mortality rates associated with pancreatic resection, complication still arise that require surgical intervention. This study reviews the pancreatic surgical experience at a major medical center to determine the overall reoperative complication rate. STUDY DESIGN: From 1985 to 1995, 107 patients underwent pancreatic resection. There were 50 pancreaticoduodenectomies, 20 total pancreatectomies, and 37 distal pancreatectomies for 102 periampullary or pancreatic cancers and five for chronic pancreatitis. The operative mortality rate was 6.5% and the morbidity rate was 43%. Ten patients (9%) developed complications that required reoperation. RESULTS: Re-exploration was performed in five patients for hemorrhage. Four patients had bleeding intra-abdominally and one had a suture line bleed. One patient developed a wound infection and fascial necrosis which necessitated reoperation. Three patients were explored for sepsis and one was found to have a pancreatic leak. One patient had persistent gastric outlet obstruction and he required conversion of the gastrojejunostomy to a Roux-en-y anastomosis. The mortality rate for re-exploration was 3/10 (30%).

Comparison of primary and reoperative surgery in patients with Crohns disease.

OBJECTIVE: This study was performed to determine the clinical results of patients with Crohns disease who require surgical resection. The outcome of patients undergoing initial surgery was compared with those having reoperation. METHODS: One hundred sixty-four patients undergoing intestinal resection for Crohns disease at The Mount Sinai Hospital from 1976 to 1989 were studied prospectively. The mean duration of follow-up was 72 months. RESULTS: Ninety patients (55%) underwent initial intestinal resection whereas 74 patients (45%) underwent reoperation for recurrent disease. Patients undergoing reoperation were older (33.4 vs. 38.7 years), had longer durations of disease (8.7 vs. 15.2 years), had shorter resections (60 vs. 46 cm), and were more likely to require ileostomy. Forty-seven percent of the patients with multiple previous resections required an ileostomy. This group also received a mean of 2.3 U blood in the perioperative period and showed a trend to increased symptomatic recurrence (49% vs. 71% at 5 years). CONCLUSIONS: Patients with Crohns disease undergoing first and second reoperation have outcomes similar to those in patients undergoing primary resection. Patients requiring multiple reoperations are more likely to require blood transfusions and permanent ileostomy and to show a greater trend to early symptomatic recurrence.

The nature and fate of categorical surgical residents who "drop out".

BACKGROUND: Little is known about the fate of categorical surgical residents who leave a program or if they differ from those who successfully complete a program. METHODS: Matching into separate categorical and preliminary categories with elimination of the pyramid began in 1982. The files of all categorical residents matched between 1982 and 1995 were reviewed for demographic and scholastic data. Drop-outs were compared with the residents who completed the program and with the current house staff. All residents have been followed up to the present. RESULTS: Between 1982 and 1996, 19 of 88 (22%) categorical residents who matched into the program left voluntarily. Eleven of 63 (17%) were male and 8 of 25 (32%) female (P = 0.12; test of proportions-Z = -1.55). They entered both surgical and nonsurgical fields. The major reasons for leaving were related to life-style issues. Their academic credentials are very similar to those who remained. CONCLUSIONS: The drop-out rate of categorical surgical residents is significant, and replacing them is not easy. We have not identified any characteristics that might predict attrition.

Engaging clinicians in a quality improvement strategy for early-stage breast cancer treatment.

Physicians are skeptical of quality improvement and obtaining their enthusiastic participation continues to be a challenge. We designed and initiated a clinician-driven quality improvement project to improve the provision of efficacious breast cancer treatments among women presenting to an academic medical center for their initial treatment of early-stage breast cancer. All 156 identified physicians agreed to participate in the project and provided access to their office records or specific medical information.

Malignant small bowel neoplasms: histopathologic determinants of recurrence and survival.

INTRODUCTION: Small bowel neoplasms account for only a small percentage of gastrointestinal tumors, but their prognosis is one of the worst. PURPOSE: This study examines the histopathology, treatment, recurrence, and overall survival of a group of patients with primary small bowel tumors. METHODS: From 1970 to 1991, a retrospective review identified 73 patients with primary small bowel tumors. Four histologic groups were identified: 1) group 1, adenocarcinoma, 29 patients; group 2, lymphoma, 18 patients; group 3, sarcoma, 8 patients; and group 4, carcinoid, 18 patients. There were 44 men and 29 women. The median age was 57 years (range, 26 to 90). Median follow-up was 15 months. Survival analysis was by the Mantel-Cox and Breslow methods. RESULTS: The most common, by type, was group 1, duodenum; group 2, jejunum; group 3, jejunum; and group 4, ileum. The preoperative diagnosis was made in only 14 patients. The median survival for adenocarcinomas and lymphomas was 13 months, 18 months for sarcomas, and 36 months for carcinoids. Curative resection could be achieved in 48 (65%) of 73 patients, and the median survival was significantly longer for this group (26 months vs. 11 months, p < 0.05). Of the 48 curative resections, 20 patients (42%) recurred: group 1, 8/19 (42%); group 2, 4/12 (33%); group 3, 4/13 (31%); group 4, 4/4 (100%). The median time to recurrence was 17 months, and the median survival after recurrence was 20 months. Adjuvant chemotherapy-radiation therapy did not alter survival in any group. CONCLUSIONS: The preoperative diagnosis of small bowel tumors rarely is made because symptoms are vague and nonspecific. Surgical resection for cure results in improved survival. Recurrence is common and survival after recurrence is poor. Other treatment methods have no role in the management of these patients.

Colorectal adenocarcinoma in Crohn's disease.

OBJECTIVE: The authors' aim was to review the clinical features and estimate the long-term survival of patients with colorectal carcinoma complicating Crohn's disease. SUMMARY BACKGROUND DATA: Recent studies have demonstrated a significantly increased risk of colorectal carcinoma in patients with Crohns disease. METHODS: The authors reviewed retrospectively the medical records of 30 patients with Crohn's disease admitted to The Mount Sinai Hospital between 1960 and 1989 in whom colorectal adenocarcinoma developed. All patients were operated on and follow-up was complete for all patients to 10 years after operation, to the time of death, or to the closing date of the study in December 1989. RESULTS: The 30 patients in the series had 33 colorectal adenocarcinomas; three patients (10%) presented with two synchronous cancers. The patients were relatively young (mean age, 53 years) and had long-standing Crohn's disease (duration >20 years in 87%). The 5-year actuarial survival was 44% for the overall series: 100% for stage A, 86% for stage B, 60% for stage C. All five patients with excluded bowel tumor died of large bowel cancer within 2.4 years; by contrast, the actuarial 5-year survival for patients with in-continuity tumors was 56%. CONCLUSIONS: The incidence, characteristics, and prognosis of colorectal carcinoma complicating Crohn's disease are similar to the features of cancer in ulcerative colitis, including young age, multiple neoplasms, long duration of disease, and greater than a 50% 5-year survival rate (without excluded loops). These observations suggest the advisability of surveillance programs for Crohn's disease of the colon similar to those for ulcerative colitis of comparable duration and extent.

A prospective, randomized trial of short versus long tubes in adhesive small-bowel obstruction.

BACKGROUND: Many cases of acute adhesive small-bowel obstruction (SBO) can be successfully treated with intestinal tube decompression. There is considerable controversy, however, regarding whether a short nasogastric tube (NGT) or a long nasointestinal tube (LT) is the best method of intestinal tube decompression. PATIENTS AND METHODS: A prospective, randomized trial was conducted to compare NGT and LT decompression with respect to the success of nonoperative treatment and morbidity of surgical intervention in 55 patients with acute adhesive SBO. RESULTS: Twenty-eight patients were managed with NGT and 27 with LT. There were 44 cases of partial SBO (23 NGT, 21 LT) and 11 cases of complete SBO (5 NGT, 6 LT). Twenty-one patients ultimately required operation, including 13 managed with NGT (46%) and 8 with LT (30%) (P = 0.16). The mean period between admission and operation was 60 hours in the NGT group versus 65 hours in the LT group. At operation, 3 patients in the NGT group had ischemic bowel that required resection. Postoperative complications occurred in 23% of patients treated with NGT versus 38% of patients treated with LT (P = 0.89). Postoperative ileus averaged 6.1 days for NGT patients versus 4.6 days for LT patients (P = 0.44). There were no deaths. CONCLUSIONS: Patients with adhesive SBO can safely be given a trial of tube decompression upon hospital admission. There was no advantage of one type of tube over the other in patients with adhesive SBO.

Jejunal obstruction as a late result of neonatal jejunal atresia.

The authors report on two adults who had jejunal dilatation after having had resection for jejunal atresia in the neonatal period. Both patients presented 20 years after the initial procedure, with severe iron deficiency anemia, marked jejunal dilatation proximal to the old anastomotic site (which was not narrowed), and a bezoar within the dilated segment. Upper gastrointestinal series were used to evaluate both patients before surgical resection of the enlarged intestine, with subsequent correction of the anemia.

Prediction of early symptomatic recurrence after intestinal resection in Crohn's disease.

OBJECTIVE: This study was performed to identify clinical criteria that may help recognize patients with Crohn's disease who are at high risk for early symptomatic postoperative recurrence. SUMMARY BACKGROUND DATA: Currently, no reliable criteria are available to help recognize patients who are prone to experience early symptomatic recurrence. METHODS: One hundred sixty-four patients undergoing intestinal resection for Crohn's disease at the Mount Sinai Hospital between 1976 and 1989 were studied prospectively. Patients with symptomatic recurrent disease within 36 months were defined as having an early recurrence. RESULTS: Multivariate analysis revealed that the number of anastomoses was the most important prognostic indicator (p = 0.001), followed by inflammation at the resection margins (p < 0.05). Patients requiring an ileostomy had a significantly lower early recurrence rate than those having single or multiple anastomoses. There was no significant correlation between inflammation at the margins and early recurrence in patients requiring an ileostomy (n = 38), or a single anastomosis (n = 98). When the margins were examined in the 28 patients with 2 or more anastomoses, 10 of 11 patients (91%) with inflammation at either margin experienced early recurrence. Patients having multiple anastomoses with normal margins had the same recurrence rate as patients with single anastomosis (42%). CONCLUSIONS: Patients with extensive Crohn's disease requiring multiple resections with anastomosis, especially when microscopic inflammation is present at the margins, are at very high risk for symptomatic early recurrence. Ileostomy seems to be associated with a significantly lower early recurrence potential than anastomosis. Further study is needed to determine whether avoidance of multiple anastomosis and adjuvant medical treatment can alter the course of the disease after intestinal resection in patients at high risk for early symptomatic recurrence.

Histopathological determinants of survival in resected cases of pancreas cancer.

We have examined the histopathological factors affecting the degree of local spread, regional lymph node (RLN) metastases, and overall survival (O.S.) in a group of 39 cases of resected carcinoma of the exocrine pancreas. Although the mean O.S. for the group was 14.3 months, resected patients without RLN involvement had a mean survival of 24 months. In contrast the mean O.S. rate was 8 months for patients with RLNs involved. Size, tumor location, and histological grade were compared to RLN involvement and O.S. The mean size of primary tumor did not differ significantly between patients with or without RLN's (r.1 versus 4.6 cms). However, 7 or 8 T1 tumors were < 4 cm and 35% of tumors < 4 cm were T1 lesions. In contrast, only 1 of 17 tumors (6%) > 4 cm was T1. Histological grade was correlated with nodal status and O.S. There was a significant difference between histological grade and the presence of metastatic lymph nodes (G1, 37% positive, G2-4.50% positive). Patients with well differentiated tumors had a mean survival of 21 months compared to a mean survival of 10 months for less differentiated tumors (p < 0.05). This difference was even more significant when stratified for nodal status. The patients with well differentiated tumors and no RLN involvement had a mean survival of 32.5 months compared to 8.6 months for well differentiated tumors with RLN involvement. In summary, we have shown that size, histological grade, and local spread predict for nodal status. However, specific patient subsets (G1, node negative) may exhibit an excellent survival when curative pancreas resection is successful.

Clinicopathologic correlations of ABO and Rhesus blood type in colorectal cancer.

There is no specific association established between colorectal cancer and blood group type. In this study, the distribution of ABO and Rh blood groups was studied in 838 patients with colorectal cancer. There was no difference in distribution of ABO blood groups between patients who were Rh+ and Rh-. There was no difference in ABO blood group or Rh factor and tumor location. The highest A/O ratio was found in rectal cancer. Although there was no difference in stage distribution for each ABO blood group, there was a significant difference between the Rh+ and Rh- groups (P < 0.037). It is not clear, however, whether the prognosis is different between the two groups since there were more early tumors as well as incurable tumors in the Rh- group. All patients with synchronous cancer were Rh+. Further studies on blood group antigens are needed to elucidate the relationship between these antigens and colorectal cancer.

Surgical treatment of tumors of the distal rectum with sphincter preservation.

One hundred one patients with villous adenoma or invasive carcinoma of the distal rectum treated with local excision or coloanal anastomosis were studied. Twenty-three (45%) of the 51 patients with villous adenomas had transanal excision, another 23 (45%) had a posterior proctotomy, and five (10%) had a coloanal anastomosis. Only two patients with a villous adenoma developed a recurrence requiring repeat local excision. Fifteen (30%) of the 50 patients with invasive cancer were treated by transanal excision. All had tumors confined to the submucosa or superficial muscularis. Eighteen (85%) of 21 patients having posterior proctotomy also had tumors with similar depth of invasion. Six (43%) of the 14 patients having coloanal anastomosis had Dukes' B tumors, six (43%) were Dukes' C, and another two (14%) underwent palliative resection. The overall actuarial 5-year survival was 77%. Only four patients treated by transanal excision or posterior proctotomy died of metastatic disease. In the coloanal group, two of 12 patients undergoing curative resection died of recurrent cancer, and another has a pelvic recurrence. Villous adenomas of the distal rectum and selected carcinomas may be treated with local excision and coloanal anastomosis with preservation of sphincter function with good results.

Malignant melanoma in inflammatory bowel disease.

Malignant melanoma occurred in 11 patients with inflammatory bowel disease (IBD). Six cases occurred in patients with ileocolitis, two in regional enteritis, one in granulomatous colitis, and two in patients with ulcerative colitis. The mean age at development of IBD was 24 yr, and at development of melanoma was 40 yr: the mean duration from onset of IBD to development of melanoma was thus 16 yr. All patients for whom complete information was available, except two, had received steroids and azulfidine for approximately a decade, as well as blood transfusions, usually multiple, and on repeated occasions. Six of the 11 patients had undergone one to seven prior operations (mean 3.5). All patients had wide radical excision of the melanoma, with or without concomitant or subsequent nodal dissection. Two patients (ages 25 and 36 yr) died rapidly from widely disseminated malignant melanoma. These cases may be coincidental, or else there may be an association between IBD and melanoma, related to immunosuppression either from the disease itself, from the medical and surgical therapy, and/or from x-ray exposure.

Lymphoma in inflammatory bowel disease.

Nine patients with lymphoma occurring in association with inflammatory bowel disease were admitted to The Mount Sinai Hospital between 1960 and 1983. Five (two men and three women) occurred among 1156 patients (0.43%) with ulcerative colitis (UC) and four (men), among 1480 patients (0.27%) with Crohn's disease (CD), a strong male preponderance in the latter group. In all four of the patients with CD and in four of the five patients with UC, the lymphomas were extraintestinal. The mean age of onset of UC in these patients was late (46 years, 19 years older than in our overall series), with lymphomas occurring a mean of only 12 years later. By contrast, patients with CD had bowel disease much younger (mean age, 26 years), and their lymphomas appeared after a longer disease duration (mean, 24 years). The risk factors for the one patient with colonic lymphoma were similar to those with colitis-associated colorectal carcinoma: extensive and long-standing colitis and relatively young age when malignant disease developed. Four of the patients with lymphoma had associated colonic carcinoma; in three of them, the carcinoma appeared within the first decade of colitis, an unusual occurrence. A second malignant lesion also occurred in three patients with UC.

Adenocarcinoma of the small intestine in Crohn's disease.

Nineteen patients admitted to The Mount Sinai Hospital with Crohn's disease between 1960 and 1989 had 20 adenocarcinomas of the small intestine. Sixteen patients had regional enteritis and three, ileocolitis. There were 15 males and four females. Carcinomas occurred in association with fistulas (four patients), fistulous tracts (three patients), excluded bowel (five patients/six cancers) and multiple strictures (three patients). None of the patients in our study had cancer develop in the first decade of Crohn's disease, and 11 had carcinoma in the third decade. As cancers occurred in three patients with multiple strictures admitted for strictureplasty, we recommend that all strictures be widely opened and carefully examined prior to strictureplasty, with frozen section biopsies of all suspicious areas. The possibility of small intestinal Crohn's carcinoma should be suspected in patients with long-standing disease, with or without excluded bowel, who present with sudden change in symptoms, especially after a lengthy quiescent period. Cancer should also be considered in patients in whom complete obstruction fails to resolve with adequate decompression and in those with multiple strictures.
