Splenic rupture at colonoscopy.

We report splenic rupture a few hours after a colonoscopy. Even though the patient had no previous history of splenic injury or symptoms attributable to splenocolonic adhesions, exploration revealed adhesions between the spleen and the colon at the level of the splenic flexure. Pathological examination revealed capsular thickening and fibrosis. Splenocolonic adhesions may lead to potentially lethal rupture of the spleen. A careful history prior to endoscopy should rule out pathological conditions that may lead to formation of adhesions between the spleen and the colon. In addition, the endoscopist should consider splenic rupture after colonoscopy in the patient who develops abdominal pain and acute anemia without evidence of intestinal perforation or external bleeding.

Approaches to the management of shotgun injuries.

Shotgun wounds present specific challenges for the surgeon. Multiple penetrating wounds frequently involve large anatomic areas with potential multi-system injury. Experience with 121 patients sustaining shotgun wounds over the 5-year period ending 31 December 1981 was reviewed to assess results and evaluate treatment protocols. Sixty-six patients had chest wounds with pleural penetration. Twenty-four wounds were minor and were observed. Each had less than five pellets penetrating the pleura. Twenty-two patients had close-range injuries. Fourteen of these required chest tube drainage alone and eight patients required thoracotomy for control of bleeding. Eleven patients died, six as a direct result of the chest injury. In 55 patients with abdominal-retroperitoneal wounds exploratory operations were done if more than four pellets were thought to be lodged intraperitoneally or if signs of peritonitis were present, while lesser wounds without peritoneal findings were observed. In the 15 patients who did not have exploratory operations, there were no deaths or major complications. Thirty-five patients had exploratory operations. Two patients had five intraperitoneal missiles and no clinical evidence of peritonitis but were found to have significant intestinal perforations. Four patients died. Eighty-three patients with extremity wounds were classified according to location of injury. Forty-five had upper extremity wounds, with nine vascular injuries. Two patients died and one limb was amputated because of soft tissue infection. Thirty-eight patients had lower extremity wounds. Five had major vascular injuries. Preoperative arteriography was obtained in 13 patients with extremity injuries; the results of one of these were falsely negative. There were no deaths or amputations.(ABSTRACT TRUNCATED AT 250 WORDS)

Differences in the clinical and radiologic patterns of rotavirus and non-rotavirus necrotizing enterocolitis.

We analyzed retrospectively 32 successive infants who developed necrotizing enterocolitis (NEC), 13 with rotavirus (RV) infection (RV+) and 19 RV-negative (RV-). All patients showed at least pneumatosis intestinalis. All patients except one had risk factors for perinatal asphyxia. Our study demonstrated significant differences between RV+ NEC and RV- NEC cases: RV+ NEC infants had a higher birth weight and were born at a later gestational age. Oral feeding was started earlier and symptoms developed later and more insidiously in RV+ patients than in RV- NEC babies. Radiology revealed a less severe and more distal colon involvement in RV+ NEC infants, whereas the RV- NEC patients mostly had small intestinal or ileocecal changes and more frequent complications of pneumoportogram and intestinal perforations. These latter infants often had a rapidly deteriorating clinical course; 84% needed surgical treatment. In conclusion RV may be a cause of NEC in susceptible infants. Historic and clinical data and a more distal colonic pneumatosis allow a differentiation of RV+ NEC from other forms of NEC.

Risk factors associated with fungal peritonitis in very low birth weight neonates with severe necrotizing enterocolitis: a case-control study.

Fungal peritonitis is uncommon in infants with severe necrotizing enterocolitis with intestinal perforation. In our institution we noted a significant (P < 0.01) increase in fungal peritonitis from 7% (3 of 45 cases of peritonitis) from January, 1980, to June, 1989, to 35% (8 of 23 cases of peritonitis) from July, 1989, to December, 1991. The mean birth weight of 11 infants with fungal peritonitis (946 +/- 70 g) (mean +/- SE) was significantly less (P = 0.008) than that of 57 infants with bacterial peritonitis (1282 +/- 52 g). In a case-control study to identify risk factors associated with fungal peritonitis, 11 infants with bacterial peritonitis were matched to the 11 infants with fungal peritonitis by age at bowel perforation and birth weight. Infants with fungal compared with bacterial peritonitis had significantly longer (P < 0.05): median duration of umbilical vessel catheterization before bowel perforation, 10 vs. 3 days, respectively; median duration of antibiotic therapy before bowel perforation, 23 vs. 14 days, respectively; and median duration of intubation, 13 vs. 5 days, respectively. Other potential risk factors that were not significant in this study included duration of central venous catheterization, total parenteral nutrition, intravenous lipid administration, aminoglycoside use, dexamethasone use or methyl xanthine therapy. In summary fungal peritonitis in neonates with necrotizing enteritis was significantly related to extremely low birth weight, prolonged umbilical vessel catheterization, prolonged exposure to antibiotics and prolonged intubation.

Colonoscopy in clinical practice.

Colonoscopy is a relatively new and important diagnostic modality for evaluation colonic disease. In order to assess its value in the community hospital, all colonoscopies done by me (250 examinations in two hospitals) were reviewed. Colonoscopy was sometimes easy and sometimes long and tedious. It was difficult to reach the cecum consistently, but success improved with experience. Many neoplasma not seen on barium enema were found, including three carcinomas. Twenty-seven polyps were removed with the aid of the colonoscopic snare. No complications occurred. Colonoscopy should probably be restricted to those physicians who have a large enough case load and who can spend enough time learning the procedure to develop expertise.

Effects of hypoxemia on early postoperative course of liver transplantation in pediatric patients with intrapulmonary shunting.

Nine pediatric patients (mean age, 10 years) with biliary atresia, who had hypoxemia related to intrapulmonary shunting, underwent living related liver transplantation. The effects of hypoxemia during the early postoperative period after liver transplantation on cardiopulmonary and renal function, as well as on transplanted liver, were analyzed. Based on the degree of shunt ratio calculated by technetium-99m macroaggregated albumin scintigraphy, the nine patients were included in the moderate group (shunt ratio under 40%, n=4) or the severe group (shunt ratio over 40%, n=5). Partial pressure of arterial oxygen was maintained at normal range in the moderate group, while that in the severe group persistently had very low values (<50 mmHg), in spite of a high degree of oxygen supply. However, all patients in the severe group maintained stable cardiopulmonary vital signs, including systemic blood pressure, heart rate, respiratory rate, and cardiac index. They also demonstrated stable renal function. None of the patients died of cardiopulmonary or renal insufficiency after transplantation, but three patients died of portal vein thrombosis, sepsis, and intracranial hemorrhage (one each). The minimal adverse effect of hypoxemia on the transplanted liver was confirmed by a rapid increase of arterial ketone body ratio, low peak values (under 200 IU/L) of aspartate aminotransferase, and a steady decrease of serum total bilirubin. Four patients encountered surgical complications, including two bile leaks from the cut liver surface, two leaks from bilioenteric anastomosis, and one intestinal perforation. Six patients suffered from bacterial infections, including four wound infections, three right subphrenic abscesses, one cholangitis, and two systemic sepses. All patients in the moderate group recovered from hypoxemia, but four of five patients in the severe group have not recovered during the follow-up period between 4 and 9 months. It was concluded that the adverse effects of hypoxemia on cardiopulmonary and renal function and transplanted liver were minimal, so that patients with severe hypoxemia could tolerate the stress of liver transplantation without special management. However, the high incidence of surgical complication and infection suggested the adverse effects of hypoxemia on wound healing and resistance to bacteria infection.

Impact of graft size mismatching on graft prognosis in liver transplantation from living donors.

BACKGROUND: Although living donor liver transplantation for small pediatric patients is increasingly accepted, its expansion to older/larger patients is still in question because of the lack of sufficient information on the impact of graft size mismatching. METHODS: A total of 276 cases of living donor liver transplantation, excluding ABO-incompatible, auxiliary, or secondary transplants, were reviewed from graft size matching. Forty-three cases were highly urgent cases receiving intensive care preoperatively. Cases were categorized into five groups by graft-to-recipient weight ratio (GRWR): extra-small-for-size (XS; GRWR<0.8%, 17 elective and 4 urgent cases), small (S; 0.8< or =GRWR< 1.0%, 21 and 7), medium (M; 1.0< or =GRWR<3.0%, 119 and 19), large (L; 3.0< or =GRWR<5.0%, 67 and 10), and extra-large (XL; GRWR> or =5.0%, 9 and 3). RESULTS: Smaller-for-size grafts were associated not only with larger and older recipients, but also with rather older donors. Posttransplant bilirubin clearance was delayed and aspartate aminotransferase corrected by relative graft size was higher in XS and S. Posttransplant hemorrhage and intestinal perforation were more frequent in XS and S, and vascular complications and acute rejection were more frequent in larger-for-size grafts. Consequently, graft survival in XS (cumulative 58% and actuarial 42% at 1 year) and S (76% and 74%) was significantly lower compared with that in M (93% and 92%) in elective cases. Graft survival in L (83% and 82%) and XL (75% and 71%) did not reach statistical significance. CONCLUSIONS: The use of small-for-size grafts (less than 1% of recipient body weight) leads to lower graft survival, probably through enhanced parenchymal cell injury and reduced metabolic and synthetic capacity. Although large-for-size grafts are associated with some anatomical and immunological disadvantages, the negative impact is less pronounced.

One hundred thirty-two consecutive pediatric liver transplants without hospital mortality: lessons learned and outlook for the future.

OBJECTIVE: Orthotopic liver transplantation (OLT) has become an established procedure for the treatment of pediatric patients with end-stage liver disease. Since starting our program in 1989, 422 pediatric OLTs have been performed using all techniques presently available. Analyzing our series, we have concluded that the year of transplantation is the most important prognostic factor in patient and graft survival in a multivariate analysis. METHODS: From April 2001 to December 1, 2003, 18 whole organs (14%), 17 reduced-size organs (13%), 53 split organs (42%; 46 ex situ, 7 in situ), and 44 organs from living donors (33%) were transplanted into 115 patients (62 male and 53 female). One hundred twelve were primary liver transplants, 18 were retransplants, one third and one fourth liver transplants. Of the 132 OLTs, 26 were highly urgent (19.7%). The outcome of these 132 OLTs was retrospectively analyzed. RESULTS: Of 132 consecutive pediatric liver transplants, no patients died within the 6 months posttransplantation. Overall, 3 recipients (2%) died during further follow-up, 1 child because of severe pneumonia 13 months after transplantation and the second recipient with unknown cause 7 months postoperatively, both with good functioning grafts after uneventful transplantation. The third had a recurrence of an unknown liver disease 9 months after transplantation. The 3-month and actual graft survival rates are 92% and 86%, respectively. Sixteen children (12%) had to undergo retransplantation, the causes of which were chronic rejection (3.8%), primary nonfunction (3.8%), primary poor function (PPF; 1.5%), and arterial thrombosis (3%). The biliary complication rate was 6%; arterial complications occurred in 8.3%; intestinal perforation was observed in 3%; and in 5%, postoperative bleeding required reoperation. The portal vein complication rate was 2%. CONCLUSIONS: Progress during the past 15 years has enabled us to perform pediatric liver transplantation with near perfect patient survival. Advances in posttransplant care of the recipients, technical refinements, standardization of surgery and monitoring, and adequate choice of the donor organ and transplantation technique enable these results, which mark a turning point at which immediate survival after transplantation will be considered the norm. The long-term treatment of the transplanted patient, with the aim of avoiding late graft loss and achieving optimal quality of life, will become the center of debate.

Immediate, early, and late morbidity with laparoscopic ventral hernia repair and tolerance to composite mesh.

The laparoscopic repair of ventral hernias is still a controversial therapeutic option, and little is known of its medium- and long-term morbidity. The purpose of the study is to evaluate the postoperative morbidity of laparoscopic ventral hernia repair and analyze the clinical factors that might be related to it. 86 consecutive patients who had ventral hernia and underwent endoscopic surgery in a Universitary teaching hospital. Epidemiological, clinical, postoperative complications, tolerance, aesthetic evaluation of the wall and recurrence rate are analyzed. The mean follow-up (100%) was 42 months (range: 1-5 years) and included clinical and ultrasonographic evaluation. The overall postoperative morbidity rate was 23.2%, with one case of mortality following a sepsis due to intestinal perforation; the rate of re-admissions and recurrences was 3.5%. Statistically significant relationships were shown between the complications and infra-umbilical location (P < 0.001), age over 60 years and female sex (P < 0.05). The dynamic ultrasound study showed 91% and 94% of the patients to be adhesion-free at 1 and 3 years respectively. Aesthetic assessment of the wall at 3 years showed persistent asymmetries in 5% of the patients and a 92% degree of personal satisfaction. The morbidity with laparoscopic ventral hernia repair is not negligible. The surgeon must know these complications and be able to treat them appropriately.

Laparoscopic versus open living-donor nephrectomy: experiences from a prospective, randomized, single-center study focusing on donor safety.

BACKGROUND: Very few randomized studies on laparoscopic (L) versus open (O) living-donor nephrectomy (LDN) have been presented. The largest randomized series reported so far included 80 donors. In 2000, an Australian safety group concluded that the evidence base for L-LDN is inadequate to make recommendations regarding safety and efficacy. METHODS: With this background, at our single national center, 122 donors were randomized to left-sided L-LDN (n=63) or O-LDN (n=59), from February 2001 to May 2004. This article summarizes our experiences, in particular regarding complications and safety. RESULTS: There were significant differences in favor of O-LDN regarding operative time, warm ischemia time, and vessel lengths, whereas the analgesic requirements and pain data were significantly in favor of the laparoscopic procedure. In the L-LDN group, there were five major postoperative complications resulting in reoperations (8%), including two intestinal perforations. No major complications occurred in the O-LDN group. CONCLUSIONS: These results from our randomized study do suggest that conventional O-LDN is a very secure procedure, superior to L-LDN regarding donor safety. There has been an unacceptably high rate of reoperations in our L-LDN series but without mortality or significant sequelae. A careful look at some other L-LDN series also suggests increased morbidity/mortality. Our data do, however, support the view that a perfect, uncomplicated L-LDN appears to be the superior procedure, and the laparoscopic procedure is still evolving. Donor safety may be improved by avoiding obese donors, stapling of the renal artery (not clipping), and perhaps by hand assistance. Furthermore, we will consider the retroperitoneal approach.

Abdominal pathology in spinal cord injured persons.

The assessment and management of abdominal disease in persons with spinal cord injuries is extremely complex. Alterations in the normal conduction of impulses to the brain can result in symptoms that may be quite unlike those which are commonly associated with abdominal pathology. A number of features, however, have been identified which can assist the practitioner in the interpretation of the clinical evaluation. This article discusses those findings and the most commonly occurring abdominal disorders in which they are seen. Two case studies are presented which exemplify the symptomatology described and which reinforce the need for early accurate diagnosis and management of abdominal disease in spinal cord injured persons.

Follow-up studies of joint complications in yersiniosis.

In 1971-73, 60 patients were hospitalized for an infectios disease caused by Y. enterocolitica serotypes III and IX or Y. pseudotuberculosis serotype I. In the spring of 1977 a follow-up study was carried out with 52 of these patients, one patient having died from intestinal perforation evidently resulting from yersiniosis-induced amyloidosis and colitis. The follow-up study showed that two patients had symptoms of sacroilitis, one had developed an apparent rheumatoid arthritis after yersiniosis and one had joint plans and a high serum rheumatoid factor titer with no objective joint changes. All results from kidney and liver studies were normal. No brucellosis antibodies were found in the follow-up study. Twelve patients had antibody titers against Y. enterocolitica serotype III.

Clinical and bacteriological profiles of patients with typhoid fever treated during 1975-1998 in the Tokyo Metropolitan Komagome Hospital.

Patients with typhoid fever presenting to the Tokyo Metropolitan Komagome Hospital during the period 1975-1998 were retrospectively investigated. All cases were diagnosed by a positive culture for Salmonella typhi in either of their clinical specimens. Of the total number of 130 patients, 57% contracted the disease abroad; this population increased in later years as the total numbers of cases decreased. The period from disease onset to diagnosis averaged 14 days with 20% of the cases requiring over three weeks to establish a diagnosis. As for symptomatology relative bradycardia was seen in less than half of the cases, and rose spots or splenomegaly in less than one third. A positive blood culture was the most frequent test establishing the diagnosis followed by a positive stool culture. Intestinal bleeding was recognized in as many as 35 cases (27%) and even intestinal perforation occurred in two cases (1.5%). Chloramphenicol was most commonly employed during the early study period, however, during the late period it was replaced by fluoroquinolones. The clinical cure rate was 98% with regimens that include fluoroquinolones/quinolone; however it was 87% with the other antimicrobial regimens. Bacteriological relapse occurred in 25% of the non-fluoroquinolone group while only in 2.0% in the fluoroquinolone/quinolone group. Four strains of Salmonella typhi that were multi-resistant to chloramphenicol, ampicillin and cotrimoxazole were isolated in travelers from Asia. Early diagnosis by appropriate bacteriological examination regardless of classical symptomatology should be stressed and the use of fluoroquinolones is warranted in the treatment of typhoid fever.

Degos disease and spastic paraplegia.

Malignant atrophic papulosis (Degos disease) is a rare disorder characterized by a vasculopathy of unknown origin. The cutaneous manifestations comprise erythematous papules, which heal to leave scars with a pathognomonic central porcelain-white atrophic area and a peripheral telangiectatic rim. There is usually involvement of the gastrointestinal tract but other organ systems can also be affected, the central nervous system being involved in 20% of cases. It is frequently fatal within 2 or 3 years from onset of systemic involvement, the cause of death usually being intestinal perforation. Our patient is of interest as she has survived an unusually long time despite florid cutaneous and neurological manifestations.

Neuropathological analysis of an asymptomatic adult case with Dandy-Walker variant.

The Dandy-Walker (DW) complex is a rare posterior fossa malformation, usually observed during the prenatal period or the early infancy. Clinically, it is characterized by mental retardation, seizures, cerebellar ataxia as well as symptoms of hydrocephalus. Structural imaging reveal a hypoplasia or agenesis of the cerebellar vermis, enlargement of the fourth ventricle with a posterior fossa cyst. Additional neurodevelopmental changes such as agenesis of the corpus callosum, lissencephaly and cortical dysplasia are also present. We report the first neuropathological analysis of an adult asymptomatic DW case. Brain computerized tomography showed a massive posterior fossa cyst and hypoplasia of the cerebellum. An Ehlers-Danlos syndrome type IV characterized by repetitive intestinal perforations and a saccular aneurysm on the left posterior communicating artery was also present. Macroscopic brain examination revealed hypoplasia of both cerebellar hemispheres and posterior part of the vermis, as well as dilatation of the fourth ventricle without hydrocephalus. The posterior fossa cyst wall was formed by an external arachnoid layer, middle layer with loose connective tissue and an internal layer of ependymal cells. There were two foci of cerebellar cortical dysplasia but no ectopic neurons, neuronal loss or gliosis in both cerebellum and cerebral cortex. No vascular or significant neurodegenerative lesions were observed. In comparison with previous reports in DW infants, this adult case displayed milder brain abnormalities compatible with a diagnosis of DW variant. The preservation of the cortical cytoarchitecture as well as the paucity of additional neurodevelopmental changes may explain the absence of clinical expression.
