A retrospective review covering a 9-year period revealed 113 patients who underwent 157 major bowel procedures during 130 operations performed solely by gynecologic oncology surgeons. Forty-eight percent of the operations were done for tumor cytoreduction, and 33% were performed for a bowel obstruction. Other indications included colostomy closure, fistula repair, resection for multiple enterotomies, temporary diversions, repair of perforated bowel, treatment for severe proctosigmoiditis, management of ureteral stricture, treatment for vulvar necrosis, and resection of an incidental small bowel tumor. Of the 157 procedures, 44% were colostomies, 32% were bowel resections with reanastomosis, 9% were urinary conduits, 6% were intestinal bypass procedures, 5% were colostomy closures, and 4% were ileostomies. Postoperative complications occurred in 32% of the 130 operations. These included wound infection, death, sepsis, fistula formation, urinary tract infection, unexplained febrile morbidity, anastomotic leakage, stomal infarction, adult respiratory distress syndrome, bowel obstruction, deep venous thrombosis, and wound hematoma. Four of the eight deaths were due to tumor progression, three were from sepsis, and one was from adult respiratory distress syndrome. Of the 130 operations, 89 (68%) were associated with no complications. These data support the concept that gynecologic oncology surgeons are able to perform intestinal operations as therapy for gynecologic malignancies with acceptable complication rates. Since a thorough understanding of the natural history of the cancer, familiarity with alternative therapeutic options, and knowledge of the prognosis are important in making operative decisions, and since gynecologic oncologists are technically capable of performing operations on the small bowel and colon, referral of patients with a primary or recurrent gynecologic malignancy or with a subsequent intestinal complication after initial therapy should be directed to the gynecologic oncologist whenever possible.

Multiorgan system failure due to hypotension and sepsis is an important cause of death in patients with bowel obstruction. We have investigated the pathophysiology of this entity in an animal model. After 5 days of bowel obstruction, blood flow in the superior mesenteric artery was measured with and without Pitressin and norepinephrine given in separate experiments. In controls, Pitressin in moderate dosages caused a substantial fall in gut blood flow, which was not seen in obstructed animals (blood flow reduction 52 percent vs. 11 percent in sham and obstructed animals respectively, P less than 0.01). Similarly, norepinephrine infusion had less of an effect on gut blood flow in obstructed animals (blood flow reduction 79 percent vs. 58 percent sham vs. obstructed animals (P less than 0.05). Thus, both agents had dose-related effects on gut blood flow, which was maintained at a higher level throughout the drug infusion periods in the bowel of obstructed animals, demonstrating that splanchnic flow is less responsive to vasoactive drug infusion under these experimental conditions. Because splanchnic vasoconstriction is an important feature of normal hemodynamic homeostasis, we suggest that these results may help explain some aspects of the pathophysiology of multiorgan failure caused or worsened by systemic hypotension seen in bowel obstruction.

Optimal surgical management of neonates with gastroschisis and omphalocele remains controversial. Suggested benefits of primary fascial closure include earlier return of gastrointestinal function, decreased hospital stay, less sepsis, less risk of postoperative intestinal obstruction and fistulae, and lower mortality. Between 1978 and 1989, 40 neonates with gastroschisis or omphalocele underwent repair. Primary fascial repair was performed in 30 children, 18 of whom had a gastroschisis and 12 of whom had an omphalocele. Ten children had staged repair with the use of a silastic silo; seven of these had a gastroschisis and three an omphalocele. Comparison between the groups was made regarding birth weight, days on the ventilator before and after surgery, days to first feeding, days in the hospital after surgery, postoperative complications, and survival. There was no significant difference in birth weight, days on the ventilator, days to first feeding, and postoperative days in the hospital. There were nine complications in nine patients (30%) with primary repair and four complications in two patients (20%) with staged repair. Two infants died after primary repair (6.7%), and one (10%) died after staged closure. It was concluded that silastic silo repair and primary fascial closure are both acceptable alternatives. Primary closure is attractive whenever possible to avoid additional operations.

The data for 77 patients with colorectal cancer who underwent emergency surgery for acute intestinal obstruction (57 patients) or perforation (20 patients) within 24 h of admission were evaluated. The patients were older and had more advanced disease than patients undergoing elective surgery for colorectal cancer. Emergency surgery for carcinoma of the right colon consisted of primary resection in 95 per cent of cases and was followed by a 28 per cent mortality rate. Perforated tumours of the left colon and rectum were managed by primary resection in 82 per cent of cases with a 22 per cent mortality rate. In contrast, obstructing tumours of the left colon and rectum were treated by primary resection in 38 per cent of cases with a 6 per cent mortality rate, and by primary decompression in 62 per cent of cases with a 25 per cent mortality rate. The overall postoperative mortality rate was 23 per cent and increased with advanced tumour disease, perforation and peritonitis. Cardiac decompensation and intraabdominal sepsis were the major causes of death. Although the long-term survival rate following emergency surgery was worse than after elective surgery, improvements in outcome should be achieved by better management of the initial emergency situation.

We have reviewed 40 patients with immune thrombocytopenia purpura (ITP) to assess current methods of preparation for surgery and to evaluate perioperative complications and response to splenectomy. Twenty-one patients had chronic ITP (greater than 1 year duration) and 19 patients had severe acute thrombocytopenia (platelet counts less than 10,000). A progression of methods of pretreatment was seen in the 10-year period reviewed. Seventeen patients received no treatment before admission for surgery, and 10 of these received platelet transfusions. Seventeen patients received steroids immediately preceding surgery; 16 of these responded and 1 received a platelet transfusion. Recently, 5 patients received intravenous gamma globulin (IgG) preceding surgery with all patients responding and none receiving platelet transfusions. One patient received a combination of steroids and IgG with good response and did not require platelet transfusion. No major postoperative complications occurred (ie, pancreatitis, small bowel obstruction, or sepsis) except for one patient requiring a secondary exploration for an accessory spleen and recurrent thrombocytopenia. Eight patients (20%), 6 with severe ITP and 2 with chronic ITP (5 males and 3 females) developed recurrence of thrombocytopenia following surgery up to 1 1/2 years after splenectomy. These patients all required further medical therapy. Three additional patients (2 chronic and 1 severe) developed thrombocytopenia following viral illnesses, but required no further therapy. Of the 8 surgical failures, 4 failed to respond to prior treatment with steroids, 1 to IgG, and 2 failed to respond to combination therapy, while one surgical failure responded to both steroid and combination therapy. Of the responders to splenectomy (32 patients), only 3 failed to respond to prior treatment with steroids.(ABSTRACT TRUNCATED AT 250 WORDS)

Between January 1982 and March 1990, 106 patients underwent restorative proctocolectomy in eight separate surgical departments. The indication for operation was ulcerative colitis in 86%, familial adenomatous polyposis in 12% and megacolon in 2%. The age at operation was 33 +/- 2 years (mean +/- sem) (range 15-55 years). There were no perioperative deaths. The principal causes of post-operative morbidity were intra-abdominal sepsis (15%), anastomotic stricture (10%) and intestinal obstruction (8%). Intestinal continuity has been restored in 99 patients. All were grossly continent, but 32% experienced occasional soiling. The mean stool frequency was 5/day and 1/night. The overall failure rate was 6%. Eighty-nine percent of patients were happy with the outcome. We conclude that restorative proctocolectomy is safe and provides acceptable functional results. It should be the operation of choice in most patients with ulcerative colitis or familial adenomatous polyposis.

One hundred nine men and 71 women with a mean age of 31 years had construction of 164 S, 2 J, and 14 other ileoanal reservoirs. Postoperative gastrointestinal complications included small bowel obstruction in 11 percent and ileus, hemorrhage, and sepsis in 6 percent, 5 percent, and 11 percent, respectively. There was a 13 percent incidence of miscellaneous postoperative complications. Pouch perianal fistulas developed in 5 percent of patients, and pouch vaginal and other pouch fistulas developed in an additional 4 percent. During long-term follow-up, small bowel obstruction developed in 27 percent of patients, and enterolysis or enterectomy was required in 15 percent of patients. One hundred fourteen patients who were followed for a mean length of 5 years after ileostomy closure (range 16 to 88 months) were evaluated for functional outcome. Function improved with time in 63 percent of patients and remained stable in another 33 percent; only 4 percent had long-term deterioration. Ninety-five percent of patients would again choose an ileoanal reservoir over a permanent ileostomy. This long-term assessment shows that although the ileoanal reservoir is a viable option in the management of mucosal ulcerative colitis, it should not be recommended to every patient.

Patients who undergo surgery for morbid obesity are often subjected to reoperation for a wide array of indications. To evaluate outcome following revisional procedures, we reviewed the records of 32 such patients treated at UCLA between April 1986 and May 1989. Twenty-five women (78%) and 7 men (22%) with a mean age of 44 years underwent 76 reoperations (2.4 per patient) for complications of prior obesity surgery. Indications for initial surgical revision consisted primarily of metabolic derangements (12 patients) and weight-related problems (11 patients). In contrast, indications for the patients' final surgical procedure were commonly for bowel obstruction (41%), intra-abdominal sepsis (12%), and gastrointestinal bleeding (6%). Following initial revision, 23 patients (71.8%) required further surgery for major complications and four patients died (12.5%). While initial revisions are frequently indicated for metabolic problems, final reoperations are more frequently undertaken for urgent, life-threatening complications. Revisional procedures for morbid obesity should be carefully considered, and the potential for major complications and/or death should be weighted heavily against proposed benefits.

Between 1974 and 1986, inclusive, over 400 newborns with clinical, radiological, and/or pathological evidence of necrotizing enterocolitis (NEC) were treated at the Hospital for Sick Children, Toronto, Ontario. Within this group were 37 babies who had a bowel perforation that was treated with peritoneal drainage under local anesthesia. Eighty-eight percent of the 41 weighed less than 1,500 g and 65% weighed less than 1,000 g; during the same time 40 other neonates (9% of the total) with perforated NEC had laparotomies. Twelve neonates (32%) required only drainage with complete recovery of their intestinal tracts. The remaining 25 (68%) fell into one of three groups: (1) nine (24%) had rapid downhill course, sepsis, and death without laparotomy; (2) nine (24%) had rapid downhill course, sepsis, and laparotomy (five deaths); (3) seven (20%) had slow development of bowel obstruction requiring operation (two deaths). The overall survival rate was 56%. These results continue to indicate that this method is effective in temporizing 88% of the small and/or very ill babies with a NEC perforation. However, an added bonus is that 32% of these newborns treated in this fashion had complete resolution of their disease.

The records of 51 patients diagnosed with enterovesical fistulas at Virginia Mason Medical Center from 1974 to 1988 were reviewed. Diverticulitis (41%), Crohn's disease (17%), and colorectal cancer (16%) were the major causes. In 50 of 51 patients, the diagnosis was made on the basis of the clinical history and the urine culture. Radiologic and endoscopic studies failed to identify the fistula in 20%, though all were confirmed at operation or autopsy. In four of eight patients with fistulas secondary to colorectal cancer, malignancy was not diagnosed preoperatively. Operation was performed in 84% of the patients. One-stage resection of the bowel was performed in 66% of patients with the intent of removing the fistula. The complication rate was 8% with no deaths. All multi-stage procedures were performed for fistulas complicated by abscess or bowel obstruction. There were two postoperative deaths in patients with metastatic cancer undergoing palliative diversion. All eight patients treated by diverting colostomy had persistent fistulas and urinary sepsis. All eight patients treated with antibiotics but without operation were free of complications of the fistula until death from other causes. Enterovesical fistula is a clinical diagnosis. Preoperative studies should be used to delineate the bowel disease and search for malignancy rather than to see the fistula, which is clinically apparent. One-stage resection of the involved bowel is the procedure of choice in the absence of abscess or bowel obstruction. When resection is not feasible, medical management with antibiotics is preferable to colostomy.
