    Notes: Abstract PURPOSE: We retrospectively reviewed the records from our past five years of experience with colostomy closure at a large multispecialty hospital to determine postoperative morbidity. RESULTS: From March 1988 to April 1993, 46 patients underwent colostomy closure. Patients ranged in age from 24 to 87 (mean, 41.8) years, and 25 (54 percent) were women. Stomas had been created during emergency operations in 40 patients (87 percent); most operations (54 percent) were for complications of acute diverticulitis. Of the 46 procedures, 40 (87 percent) were end colostomies, and 6 were loop colostomies. Stomas were closed at a range of 11 to 1,357 days after creation (mean, 207 days; median, 116 days). Twenty-six patients (57 percent) underwent colostomy closure alone, and the remainder underwent additional procedures ranging from appendectomy to hepatic lobectomy. Duration of operations ranged from 1 to 9.5 (mean, 4.2) hours, and estimated blood loss averaged 400 ml. Overall hospital stay for closure was 6 to 62 (mean, 11.5) days. Inpatient complications occurred in 15 percent of patients, including congestive heart failure (2 percent), cerebrovascular accident (4 percent), pneumonia (2 percent), enterocutaneous fistula (2 percent), and pulmonary embolus with death (2 percent). The most common longterm complication was midline wound hernia, which occurred in 10 percent of surviving patients. Overall, complications occurred in 24 percent.CONCLUSIONS: Colostomy closure is a major operation; however, with good surgical judgment and technique, associated morbidity and mortality can be minimized.

    Notes: Abstract PURPOSE: The study contained herein was undertaken to establish the incidence of small-bowel obstruction, adhesiolysis for obstruction, and additional abdominal surgery after open colorectal and general surgery. METHODS: A retrospective cohort study was performed using patient-specific Health Care Financing Administration data to evaluate a random 5 percent sample of all Medicare patients who underwent surgery in 1993. Of these, 18,912 patients had an index abdominal procedure. Two-year follow-up data documented outcomes of hospitalizations with obstruction, adhesiolysis for obstruction, and/or additional open colorectal or general surgery. RESULTS: Within two years of incision, excision, and anastomosis of intestine (International Classification of Diseases (ICD)-9 code 45), 14.3 percent of patients had obstructions, 2.6 percent required adhesiolysis for obstructions, and 12.9 percent underwent additional open colorectal or general surgery. After other operations of intestine (ICD code 46), 17 percent of patients had obstructions, 3.1 percent required adhesiolysis for obstructions, and 20.2 percent underwent additional open colorectal or general surgery. After operations of rectum, rectosigmoid, and perirectal tissue (ICD code 48), 15.3 percent of patients had obstructions, 5.1 percent required adhesiolysis for obstructions, and 16.4 percent underwent additional open colorectal or general surgery. After other operations on the abdominal region (ICD code 54), 12.4 percent of patients had obstructions, 2.3 percent required adhesiolysis for obstructions, and 8.8 percent underwent additional open colorectal or general surgery. CONCLUSIONS: In this retrospective study of Medicare patients, we learned that bowel obstruction, adhesiolysis for obstructions, and additional abdominal surgery occurred more often after abdominal surgery than was previously published.

    Notes: Abstract PURPOSE: The purpose of this study was to document prospectively the time required to gain access to the abdomen to perform a planned procedure in patients with and without previous surgery. METHODS: Patients were obtained from the consecutive cases of 11 surgeons at three colorectal surgery centers. Opening time (skin incision to retractor placement) was measured and recorded in the operating room by the circulating nurse or by an independent researcher. Demographic data including the number and type of previous operations and the presence and severity of adhesions were recorded by the staff surgeon. A comparison of opening times between patients with and without previous abdominal operations was conducted. RESULTS: One hundred ninety-eight patients had abdominal operations. Fifty-five percent had previous abdominal procedures. Patients with prior surgery required a mean of 21 minutes to open their abdomens, whereas patients without prior surgery required a mean of 6 minutes (P〈0.01). The median times were 17 and 6 minutes, respectively. Eighty-three percent of patients with prior surgery had adhesions, whereas only 7 percent of patients had adhesions on their initial operation. Patients with prior surgery also had higher grade adhesions (P〈0.001). Irrespective of previous surgery, comparing patients with adhesions with those without, patients with adhesions required a mean of 22 minutes to open, whereas the lack of adhesions resulted in a mean opening time of 6 minutes. CONCLUSIONS: Previous surgery and the presence of adhesions add significant time to opening the abdomen.

    Notes: ---A series of m-terphenyl-based ligands bearing three coordinating oxyacetate and two amido or two sulfonamido groups, (1a-b)H3 and (2)H3, respectively, have been synthesized and characterized. The structures of the corresponding neutral complexes have been studied using 1H-NMR spectroscopy and luminescence experiments. The photophysical properties of the (1a-b)Eu, (2)Eu, (1a)Tb, and (2)Tb complexes have been studied to determine the structure of the first coordination sphere in methanol. The first coordination sphere consists of eight donor atoms provided by the ligand (three chelating oxyacetate groups and two amide or sulfonamide oxygens), and one methanol molecule. The (1a)Dy and (1a)Sm complexes exhibited sensitized luminescence in the visible spectral region, but the luminescence intensity was very sensitive to quenching by C-H groups. The near-infrared emitting (1a)Ln and (2)Ln complexes exhibited sensitized luminescence at wavelengths (at 880, 1060, and 1330 nm for Nd3+, at 980 nm for Yb3+, and at 1550 nm for Er3+) of interest for applications in optical telecommunication devices. The luminescence lifetimes of these complexes in DMSO and [D6]DMSO are in the range of microseconds. The luminescent state of the NIR emitting lanthanide ions is very efficiently quenched by high frequency oscillators (such as C-H groups) in the solvent and the ligand.Supporting information for this article is available on the WWW under //http://www.wiley-vch.de/contents/jc_2046/2000/99457_s.pdf or from the author.

    Notes: Konformationsumwandlungen in N-Methyl-azacyclohexanen haben eine Besonderheit: Sie können sowohl unter Ringinversion als auch unter Stickstoffinversion verlaufen. Durch beide Vorgänge wird eine äquatoriale N-Methylgruppe in eine axiale umgewandelt und umgekehrt. Es ist zweckmäßig, die Energiebarrieren für die N-Methylinversion in zwei “Halbbarrieren„ für die Schritte axiale Form → Übergangszustand und äquatoriale Form → Übergangszustand zu zerlegen und beide Werte getrennt anzugeben. - In diesem Beitrag werden die N-Methylinversionsbarrieren zahlreicher methylierter Oligoazacyclohexane, auch mit Sauerstoff- oder Schwefelatomen im Ring, diskutiert.

    Notes: Condensation of cis-2-aminomethylcyclohexanol with p-nitrobenzaldehyde under mild conditions initially gives the imine as the kinetically controlled product. The imine undergoes a solid-state rearrangement to the bicyclic tetrahydro-1, 3-oxazine. The kinetics of the rearrangement were followed by solid-state CP/MAS 13C NMR spectroscopy over the temperature range 283-297 K and the reaction was shown to have an activation energy of 85.0 ± 14.7 kJ mol-1. The probable reaction mechanism is discussed.
