The complement-mediated opsonic activity (CMOA) in intra-abdominal exudates collected during laparotomy from peritonitis patients was examined by an in vitro phagocytic bactericidal assay. It was found that infected intra-abdominal exudates barely promoted detectable killing of Escherichia coli 01 by polymorphonuclear leukocytes. Only the minority of bacteria recovered by differential centrifugation from the infected exudates had C3 on their surfaces. Such bacteria were not optimally opsonized in vivo, whereas they became fully coated with C3 during a brief incubation in vitro in normal human serum. The low level of CMOA in the peritoneal fluid paralleled a depletion of complement in the peripheral blood. Thus, in cases complicated by
sepsis
with gram-negative bacteria, the CMOA in the blood was extremely low. These data suggest that the high susceptibility of the peritoneum to infection by
gut
flora, despite the normal phagocytic response, may be partly explained by the low local level of functional complement which is inadequate for optimal opsonization of the bacteria.

In this prospective, randomized study, 121 elective colorectal surgery patients had whole-
gut
lavage (n = 67) or enemas and purgatives (n = 54). Patient characteristics were well matched. Intravenous metronidazole and tobramycin were administered preoperatively initially in 53 patients, with the remaining 68 patients receiving the drugs perioperatively. Bowel preparation was satisfactory (minimal or no contents remaining) in 92.8 percent of patients with whole-
gut
lavage and 92.6 percent with enemas and purgatives (p = 0.72). Nasogastric tube insertion was poorly tolerated by 39 percent of the patients receiving whole-
gut
lavage, and enema tube insertion by 23 percent with enemas and purgatives. Fluid infusion tolerance was similar with both techniques. Abdominal wound
sepsis
occurred in 22 patients (18.8 percent), being unrelated to mechanical preparation or antimicrobial prophylaxis (p = 0.19). Colostomy closure was associated with a 42.8 percent
sepsis
rate. Excluding this group, wound
sepsis
with the remaining procedures was 13 percent (statistically significant, p = 0.03). Other complications included intraabdominal abscesses (3.3 percent), anastomotic leaks (2.5 percent), eviscerations (1.6 percent), and an operative mortality of 1.6 percent. We have concluded that whole-
gut
lavage and enemas and purgatives are equally efficacious mechanically with similar associated wound
sepsis
rates.

In a hamster model of non-Hodgkin's lymphoma which closely parallels the disease in man, and which is induced by an unusual agent(s), a diarrheal bowel disease was a major cause of mortality. This study was initiated to characterize this bowel disease and its relation to lymphoma induction and to natural diseases seen in the hamster. The studies showed that the bowel disease was an ulcerative process and was distinct from natural diseases. The incidence of the bowel disease correlated directly with that of the lymphoma in repeated epizootics, in titration studies, and in agent inactivation tests. The ulcerative bowel lesions were seen at the same stage of the disease as acute and chronic inflammatory infiltrates with necrosis in the thymus and mesenteric lymph nodes. Since necrosis in the
gut
-associated lymphoid tissue can lead to perforation and
sepsis
, these bowel lesions were lethal, whereas similar necrosis in other lymphoid tissues (thymus and lymph nodes) could be clinically undetectable. Similar lesions have been reported in man. The ulcerative bowel disease was a reliable early clinical marker for exposure of hamsters to this lymphomagenic agent(s).

Fifty-two patients with reflux oesophagitis resistant to medical treatment were randomized at operation to receive either the Angelchik prosthesis or a fundoplication. All patients were assessed postoperatively by a physician unaware of the nature of the operation. Forty-two patients have been followed up for 1-2 years; ten patients for 3-9 months. Ninety-six per cent of the Angelchik patients had satisfactory or excellent results compared with 81 per cent with a fundoplication. There were no failures to control reflux with the Angelchik prosthesis whereas 6 patients (23 per cent) of the fundoplication group have persisting reflux. Operating times for insertion of the prosthesis averaged a little over half that recorded for fundoplication. Complication rates were similar. The results of the trial encourage the use of the prosthesis in patients with gastro-oesophageal reflux, where medical treatment has failed. The prosthesis should not be used if the
gut
is opened during operation either inadvertently or deliberately, as in making a suture line or anastomosis, because of the risk of
sepsis
.

Six infants with short-
gut
syndrome refractory to medical management underwent isoperistaltic colon interposition (length 11.7 +/- 3.1 cm.). The abdominal catastrophes that required extensive intestinal resection were: volvulus (3), necrotizing enterocolitis (2), and gastroschisis with intestinal atresia (1). No infant had another major congenital anomaly. The average trial of attempted medical therapy prior to colon interposition was 5.5 +/- 3.6 months. There was no perioperative mortality or morbidity associated with the colon interposition. Following the colon interposition, three infants were weaned from total parenteral nutrition (TPN) in 3 +/- 1 months and all survived. In contrast, three infants could not be withdrawn from TPN and they died secondary to complications of TPN (2 from
sepsis
and 1 from hepatic failure). Long-term survival was associated with a greater length of small bowel remaining after the initial resection (51 +/- 12 cm v 35 +/- 24 cm), colon interposition at a younger age (3 +/- 1 months v 8 +/- 3.5 months), and a shorter duration of medical management prior to colon interposition (2.8 +/- 0.8 months v 6.7 +/- 5.0 months). All survivors are now tolerating a regular diet and having one to four formed stools per day. Normal somatic growth and developmental milestones are being achieved. The follow-up period is from 24 to 84 months. Our experience with the colon interposition in the patient with short gut syndrome has led us to conclude that when a reasonable trial of medical management has failed, a colon interposition is a safe and effective adjuvant to treatment.

Primary peritonitis accounts for 1 to 2 per cent of all paediatric abdominal emergencies and for about 15 per cent of diffuse peritoneal
sepsis
. The condition is still mainly seen in infants and in mid-childhood years, Most frequently in children four to eight years of age, with females outnumbering the males except among neonates where the males predominate. The mortality rate is about 50 per cent for infants, but drops to 10 to 15 per cent in older children. The origin of the infecting organism may be a haematogenous spread or ascension through the female genital tract, but transdiaphragmatic lymphatics and transmural migration through the
gut
wall may also be possible sources. The incidence of primary peritonitis is increased in children with nephrotic syndrome, postnecrotic cirrhosis with ascites and immunologic deficiency. Practically all kinds of pathogenic organisms are found, but a relative increase in staphylococcal and gram-negative infections has been noted.

Eight patients with aplastic anemia were transplanted with marrow from HLA-identical donors. Two patient rejected their grafts and died while 5 patients (71%) show no ill effects 3 months, 10 months, and more than 1, 2 and 4 years after the transplantation. Three of the patients who received unirradiated donor buffy coat after transplantation developed chronic graft-versus-host disease (GVHD) which, however, resolved following treatment with Prednisolone and Azathioprine. One patient with end-stage acute myeloid leukemia, who was transplanted with marrow from an identical twin, died 6 days after the transplantation of bleedings and
sepsis
. Eight patients with acute non-lymphoblastic leukemia (ANL) were transplanted, while in remission, with marrow from HLA-identical siblings. One patient died of interstitial pneumonia 3 months after transplantation, while another patient recovered from GVHD of the
gut
at 5 months after the transplantation. Seven out of 8 patients with ANL (88%) are home and well between 2 and 12 months after the transplantation.

Nitrogen flux across the splanchnic bed is altered following operation, injury, and
sepsis
, but the individual contributions of
gut
and liver and their interrelationships remain undefined. Since more than 60% of whole blood amino acid nitrogen is transported as glutamine and alanine, we determined the flux of these amino acids across the gastrointestinal tract and liver in splenectomized, awake dogs during a control period and a 2 and 4 days following a standard laparotomy. Blood flow was measured in all studies and substrate flux calculated from flow and arteriovenous and portovenous concentration differences. Portal blood flow decreased by 25% following operation from a control value of 26 +/- 2 ml/kg body weight . min to 19 +/- 2 (P less than 0.05). Total hepatic blood flow did not change significantly after operation, but the individual contributions of the hepatic artery and portal vein were altered; hepatic artery flow increased from a control value of 10 +/- 1 ml/kg . min to 23 +/- 3 (P less than 0.001). Glutamine uptake by teh gastrointestinal tract nearly doubled from a control value of 0.75 +/- 0.16 microM/kg . min to 1.31 +/- 0.13 (P less than 0.05) on postoperative day 2. This increase in flux occurred despite a diminished arterial concentration and a reduced portal blood flow, indicating that extraction of glutamine by the gastrointestinal tract was not primarily dependent on increased arterial concentration. Alanine, on the other hand, was released by the
gut
at a rate of 1.97 +/- 0.37 microM/kg . min in controls and decreased to 0.81 +/- 0.13 microM/kg . min (P less than 0.05) in dogs that had operation. Glutamine was released by the liver in control dogs at a rate of 1.59 +/- 0.59 microM/kg . min but switched to an organ of slight glutamine uptake (0.31 +/- 0.31, P less than 0.01) on postoperative day 2. Alanine uptake by the liver doubled from 2.94 +/- 0.29 to 5.46 +/- 0.63 microM/kg . min (P less than 0.05) following surgical stress. The gastrointestinal tract plays an active metabolic role in the processing of amino acids following operation and may be a key regulatory of interorgan substrate flux following injury and infection.

Whole-
gut
irrigation was used to prepare 43 patients for colorectal surgery. Antibiotics were used pre-operatively in the first group and added to the irrigation fluid in the second. The condition of the bowel lumen was regarded as perfect or good in 87,2% of cases, and the total
sepsis
rate was 15,4%. The results are regarded as a significant improvement on conventional methods of bowel preparation.

Sepsis
secondary to bacterial translocation is common in infants with short bowel syndrome (SBS). Although early feeding is advocated to enhance adaptation in SBS, the effects of feeding on
sepsis
in SBS patients have not been examined. Twenty-one infants and children (aged 2 months to 3 years) with SBS (< 80 cm small bowel length) from a variety of causes (15 necrotizing enterocolitis, 2 atresia, 2 gastroschisis, 2 volvulus) had follow-up prospectively for septic episodes before and after feedings were initiated, while still receiving total parenteral nutrition. The incidence and number of septic episodes and microbiology (blood cultures) were tabulated and compared with those of 20 patients with similar ages, and diagnoses without SBS. Statistically significant differences among infants with SBS were noted with respect to
sepsis
incidence (6 of 21 [29%] NPO v 16 of 21 [76%] feeding) number of septic episodes (1.3 +/- .2 NPO v 4.2 +/- .4 feeding), and presence of gram-negative rods causing bacteremia (1 of 6 [17%] NPO v 13 of 16 [81%] feeding) (all: P < .05). There were similar differences between SBS and non-SBS infants. These data show that enteral feeding increases the incidence and number of episodes of
sepsis
in SBS infants, but not in matched non-SBS patients. The predominance of gram-negative organisms in
sepsis
in SBS suggests increased
gut
bacterial translocation in these patients, implying that selective
gut
decontamination may reduce the episodes of bacteremia.
