We designed a model of intestinal obstruction (IO) to study the histological alterations in the intestinal wall and the mesenteric lymph nodes (MLN). Therefore we used 32 Sprague-Dawley rats and under anesthesia a laparotomy was performed and the distal ileum was ligated with 3-0 silk, producing a complete occlusion. At different interval (24, 48, 72 and 96 hours) the animals were sacrificed by cervical dislocation and were histologically analyzed. At 24 hours post IO, congestion, edema and a inflammatory infiltrate were observed at the level of the lamina propia and the MLN were reactive. At 48 hours the congestion and edema increased and the intestinal mucosa began to fragment, allowing the bacteria to translocate and getting to the lymph nodes in the intestinal wall. The reactivity at the MLN increased. The observation of bacterial translocation in IO widen the scope of the alterations in this pathology, were not only absorption of toxic products and endotoxin occurs in the compromise segment and this phenomenon could explain the incidence of bacteremia and sepsis in the IO patients.

The experience gained with restorative proctocolectomy and ileal reservoir in 60 patients is presented. Fifty-two patients had W reservoirs and the operative technique of the procedure is described in detail. Forty patients had a defunctioning ileostomy and 20 had a single stage procedure. There was no perioperative mortality. The main complications were sepsis (28 per cent), intestinal obstruction (18 per cent) and reservoir ileitis (20 per cent). There was a significant improvement in sepsis rate (from 20 to 4 per cent) and hospital stay (from 31.8 to 15.6 days) with increased experience. The functional results of 48 patients with W reservoirs was assessed. The mean number of evacuations per 24 h (+/- s.d.) was 3.8 +/- 0.2. Sixty-five per cent of patients did not evacuate at all, or rarely, at night and none evacuated more than once at night. Forty-four per cent of patients took antidiarrhoeal agents. Continence was normal in 50 per cent of patients. Minor leakage occurred in 46 per cent of cases, frequent leakage in 4 per cent and incontinence in none. Sexual function in 29 men was normal. Ninety-four per cent of patients considered the results of their operation to be good or excellent.

The aim of this study was to compare the immediate postoperative results and the long-term outcome of ileal pouch-anal anastomosis in 94 patients with familial adenomatous polyposis to those in 758 patients with ulcerative colitis. Two colitis patients died after operation (0.3%), but no polyposis patients died. Overall operative complications appeared in 26% and 29% of polyposis and colitis patients, respectively (NS). Reoperation for intestinal obstruction did not differ between the two groups, but sepsis requiring reoperation was more common in colitis patients (6%) than in polyposis patients (0%, p less than 0.04). At follow-up (mean, 3 years), polyposis patients had fewer daytime stools (4.5 stools per day), less nighttime fecal spotting (26%), and less pouchitis (7%) than colitis patients (5.8 stools per day; spotting, 40%; pouchitis, 22%; p less than 0.002). The conclusion was that polyposis patients tolerated the operation better and had less long-term disability than did colitis patients. The data suggest that postoperative sepsis, daytime stooling frequency, nocturnal incontinence, and pouchitis may be, at least in part, disease related and not surgeon or operation related.

Thirty-six major abdominal operations were performed on 35 Acquired Immune Deficiency Syndrome (AIDS) patients (33 men, two women). Twenty-two elective operations were indicated for diagnosis of abdominal or retroperitoneal mass (6), incomplete bowel obstruction (5), intra-abdominal infection (4), biliary symptoms (3), thrombocytopenia (3), and toxic megacolon (1). Fourteen emergency operations were for perforated viscus or peritonitis (11), massive gastrointestinal bleeding (2), and cecal volvulus (1). In 5 of 22 (23%) elective operations AIDS was unknown to the treating physicians until diagnosed by the surgical pathology; in contrast, all 14 emergency operations were in patients who had a known diagnosis of AIDS. The operative findings were related to AIDS in 34 of 36 (94%) operations. Cytomegalovirus was the most common pathogen, isolated or identified microscopically in 11 patients (eight emergency and three elective operations). Mycobacterial infections presented as retroperitoneal adenopathy or splenic abscess in six patients. Non-Hodgkins lymphoma was the most common malignancy found, presenting as an abdominal mass (4), bowel obstruction (3), or with gastrointestinal bleeding (2). Kaposi's sarcoma was diagnosed at laparotomy in four patients. The 1-month operative mortality rate for elective operation was 9% (2 of 22) and 46% (6 of 13) in emergencies. Postoperative complications included 1 reoperation for sepsis caused by inadequately resected CMV colitis; 1 pancreatic fistula; 1 wound dehiscence, and 2 minor wound infections.

In 126 consecutive patients operated on for carcinoma of the lower two-thirds of the rectum, a consistent policy of sphincter preservation resulted in 100 (79 per cent) having anterior resection and 22 (17 per cent) abdominoperineal resection. Perioperative complications in the anterior resection group were: death (two patients), clinical leakage (three patients), pulmonary embolism (five patients), pelvic haematoma (one patient), small bowel obstruction (one patient) and wound sepsis (six patients). Of 55 patients who had a potentially curative anterior resection with follow-up of at least 2 years, one developed local recurrence. Five per cent of patients had significant continence problems. Low anterior resection for carcinoma is associated with low perioperative morbidity, satisfactory functional results and acceptable local recurrence rates.

1. Widespread visceral and intestinal wall metastases are present in women dying with ovarian cancer. Intestinal wall invasion is commonly found at autopsy and is associated with bowel obstruction. Liver parenchymal replacement by metastases in more extensive than that in the lung, where most metastases have a subpleural location. Multifocality characterizes metastases in both of these organs. 2. Neoplastic lymphatic invasion is common. Lymphatic and blood vascular invasion are associated with an increased incidence of metastases in lymph nodes, small bowel wall, pancreas, lungs, ureter, and liver. 3. The mean survival time from diagnosis to death is less than 2 years. Both increasing neoplastic histological grade and clinical stage at diagnosis are associated with decreased survival time. 4. The most common causes of death are carcinomatosis, infection, or a combination of these processes. Sepsis, pneumonia, or both of these account for most of the fatal infections. 5. Bowel and ureteral obstruction constitute the most common forms of tumor-induced morbidity. The former process tends to be multifocal, involving the small and large intestines, and it is found during the disease course as well as at autopsy. Ureteral involvement is usually associated with hydronephrosis and is bilateral in approximately one fourth of the cases.

One hundred consecutive patients treated by restorative proctocolectomy with construction of an ileo-anal anastomosis and a J-shaped (n = 90) or an S-shaped ileal reservoir were studied prospectively to evaluate postoperative complications and functional outcome and to search for factors that might influence results. There were no deaths. Postoperative complications requiring surgery were pelvic sepsis (3 patients), pouch-related fistula (2), peritonitis following ileostomy closure (3) and small bowel obstruction (6), with an overall relaparotomy rate of 14%. The cumulative risk of pouchitis was 30% at 2 years. The average stool frequency decreased gradually, stabilizing at about five evacuations/24 h after 1 year. At that time 9% of patients still had greater than or equal to 7 day-time evacuations and 40% had night evacuations (greater than 1/week). These parameters did not improve further with time. Mucous soiling, a frequent problem initially, also diminished with time, occurring in 30% of patients at 1 year. At 2 years, however, this mucous leak occurred in only 20%, suggesting that improvement of continence can be expected to occur even beyond one year. Despite defects in function patient satisfaction was generally excellent. So far only three patients have preferred conversion to an ileostomy. To establish which factors might influence the functional results a specially designed scoring system, combining all functional variables, was used. It was shown that results deteriorated with increasing age and that elderly women tended to have a poorer result than elderly men. Sex, previous parity or postoperative complications appeared not to affect the functional outcome. Male sexual disturbances occurred in 8%.(ABSTRACT TRUNCATED AT 250 WORDS)

Postoperative course is reported in 52 children with malignant tumors (neuroblastoma, Wilms-tumor, non-Hodgkin-lymphoma, osteosarcoma etc.) who were operated on between 1979 and 1987. 26 children received chemotherapy prior to surgery, whereas 26 children were operated on without preceding chemotherapy (control group). Most children were under six years of age. 15 Children (57.7%) with preoperative chemotherapy developed early postoperative complications, such as sepsis, pneumonia, suture dehiscence, woundhealing disturbances and ileus, whereas this was the case in only 5 children (19.2%) without preoperative chemotherapy (P 0.0005). Four of the children with preoperative chemotherapy (15.4%) sustained late complications, such as local recurrence or mechanical bowel obstruction, whereas none of the control children did so. Lethality rate from underlying disease did not differ in both groups during follow-up (5 = 19.2% vs. 5 = 19.2%). This demonstrates that the surgeon must carefully be aware of an increased possibility of early and late complications in children who have to undergo surgery for malignant tumors following preoperative chemotherapy.

Ninety-three patients who underwent surgery were studied retrospectively over a five-year period for complications of diverticular disease, including free perforation in 32 patients (with fecal peritonitis in 8), inflammation or peritonitis in 22 patients, an abscess in 11 patients, and intestinal obstruction in 14 patients. Sixty-eight patients (73 percent) had systemic symptoms and signs consistent with serious sepsis. There has been a growing popularity of the Hartmann procedure throughout the study period. The overall 30-day mortality rate was 10.8 percent. Because of a high proportion of poor-risk patients, the Hartmann group fared particularly badly compared with those who had other operations, with a 28 percent mortality rate, 69 percent incidence of major complications, and one third of the survivors having a permanent colostomy. Other operative procedures are discussed, but until prospective data become available, it is unlikely that the widespread popularity of the Hartmann procedure will decline. Therefore, the importance of meticulous attention to technical detail is stressed if results are to improve.

Between January 1 1974 and October 31 1987, 98 patients with biopsy proven unresectable adenocarcinoma of the pancreas were treated with I-125 implants during laparotomy. Presenting symptoms were pain (57 patients), jaundice (45 patients), and weight loss (34 patients). All patients underwent laparotomy and surgical staging. Thirty patients had T1NoMo disease, 47 patients had T2-3NoMo disease, and 21 patients had significant regional lymph node involvement (T1-3N1Mo). The surgical procedure performed was biopsy only (16 patients), gastric bypass (36 patients), biliary bypass (49 patients), and partial or total pancreatectomy with incomplete resection (5 patients). The total activity and the number of seeds used were determined from the Memorial Sloan Kettering Cancer Center (MSKCC) nomogram. Stereoshift localization X ray films were taken 3-6 days after operation. The mean activity, minimal peripheral dose (MPD), and volume of the implants were 35 mCi, 13,660 cGy, and 53 cm3, respectively. In addition, 27 patients received postoperative external irradiation and 27 patients received chemotherapy. Postoperative complications were observed in 19 patients. These included post-operative death (1 patient), biliary fistula (4), intraabdominal abscess (4), GI bleeding (3), gastric or small bowel obstruction (6), sepsis (5), and deep vein thrombophlebitis (4). Pain relief was obtained in 37/57 patients (65%) presenting with pain. A multivariate analysis showed that four factors significantly affected survival: T stage, N stage, administration of chemotherapy, and more than 30% reduction in the size of the implant on follow-up films. The median survival for the entire group was 7 months. A subgroup of patients with T1No stage disease who received chemotherapy survived 18.5 months. The indications for I-125 seed implantation in unresectable carcinoma of the pancreas are discussed.
