RESUMEN

BACKGROUND: The aim of the survey was to assess the incidence of anastomotic leaks (AL) and to identify risk factors predicting incidence and gravity of AL after low anterior resection (LAR) for rectal cancer performed by colorectal surgeons of the Italian Society of Colorectal Surgery (SICCR). METHODS: Information about patients with rectal cancers less than 12 cm from the anal verge who underwent LAR during 2005 was collected retrospectively. AL was classified as grade I to IV according to gravity. Fifteen clinical variables were examined by univariate and multivariate analyses. Further analysis was conducted on patients with AL to identify factors correlated with gravity. RESULTS: There were 520 patients representing 64% of LAR for rectal cancer performed by SICCR members. The overall rate of AL was 15.2%. Mortality was 2.7% including 0.6% from AL. The incidence of AL was correlated with higher age (p<0.05), lower (<20 per year) centre case volume (p<0.05), obesity (p<0.05), malnutrition (p<0.01) and intraoperative contamination (p<0.05), and was lower in patients with a colonic J-pouch reservoir (p<0.05). In the multivariate analysis age, malnutrition and intraoperative contamination were independent predictors. The only predictor of severe (grade III/IV) AL was alcohol/smoking habits (p<0.05) while the absence of a diverting stoma was borderline significant (p<0.07). CONCLUSION: Our retrospective survey identified several risk factors for AL. This survey was a necessary step to construct prospective interventional studies and to establish benchmark standards for outcome studies.

RESUMEN

INTRODUCTION: What impact does the use of new drugs and latex gloves it have on the frequency and the severity of peri-anaesthetic anaphylactoid reactions? Does the evolution of in vitro techniques does represent a progress in the imputability of the substances at the origin of the shock? THE METHODS: They include the letter from the anaesthetic doctor, the questioning by the allergologist, skin tests (Pricks, IDR) with the anaesthetic substances and the latex according to the GERAP protocol and the biologic tests (Human Basophilic Degranulation test (TDBH), Radio ImmunoAssay (RIA), leukotrienes E4 assay (LTC4), Flow Cytometry (CMF)). THE RESULTS: 386 patients were explored (289 women and 88 men, mean age 41.5 years). The muscle relaxants are the first cause of anaphylaxis 77%. Muscle relaxants cross allergy is found in 55.1%. The Latex, tested since 1989 with Allerbio and Stallergenes extracts, is responsible for 25 shocks with one death and 15 with grade III or IV. Preventive antibiotherapy, since consensus meeting of 1992, seems responsible of 17 accidents. 116 TDBH, 216 RIA, 17LTC4 and 47CMF. TDBH are made concordant with skin tests in 48.2% against, 71.2% for the RIA. CONCLUSION: The experience of 17 years of allergo-anaesthetic consultation confirms the first row for the muscles relaxants for the target of anaphylactic shock, but the imputability of Vecuronium and Rocuronium increases to the detriment of the Suxamethonium. The Latex is in the second row, but the target questioning, the systematic use of Prick tests and "latex free" surgery room limit its increase which should change down. The antibiotherapy occupies the third row and might increase. 54 accidents have remained unexplained.

RESUMEN

We present our experience in malabsorbitive procedure in bariatric surgery based on Biliopancreatic Diversion (BPD) with transitory gastroplasty. Since 1995 we operated on 74 patients with BPD coupled with gastroplasty which is transitory due to the presence of a band in polidioxanone (PDS). The technique, proposed by Vassallo et al. in 1992, involve the respect of the duodenal bulb (5 centimeter from the pylorous) making an end-to-side duodeno-ileal isoperistaltic anastomosis. The initial excess weight loss was satisfactory (69.8% +/- 11.4% after 1 year) and it kept being stable during all the follow-up (75.2% +/- 6.4% after 5 years). The mortality was absence. We didn't observe ipoalbuminemia, diarrhea or halitosis in any patients. Only 1 patient (1.3%) developed an anastomotic ulcer. After 5 years follow-up we observed 2 cases (12.5%) of chronic hypochromic anemia and 1 case (6.2%) of hypocalcemia. We didn't perform any restorative operation. We consider this technique a good malabsortive procedure able to obtain a satisfactory and stable weight loss, with a low incidence of complications. Moreover it could be applied in patients previously treated by an ineffective gastroplasty.

RESUMEN

STUDY AIM: The aim of this retrospective study was to compare two concurrent series of patients operated on for inguinal hernia with the same laparoscopic procedure, the first one in a teaching hospital with a number of trained surgeons and the second one in a private center with only one trained surgeon. PATIENTS AND METHOD: Five hundred and forty-one patients with 757 hernias were operated on over a period of six years by a totally pre-peritoneal laparoscopic approach. Two hundred and sixteen patients were operated on in a teaching hospital by 48 surgeons (six senior and 42 trainee surgeons; group I), 325 were operated on in a private center by one surgeon who had been trained in the same teaching hospital (group II). The two groups of patients and their hernias were comparable. The comparison was established on the following criteria: duration of operation, rate of conversion, length of hospitalization, morbidity and mortality rate, recurrence rate and costs. RESULTS: Operations performed by surgical trainees were associated with: (1) a mean operative time significantly (P = 0.01) longer for both unilateral (68 vs. 41 min) and bilateral (108 vs. 68 min) hernias. The operative time did not change in the teaching hospital and decreased with experience in private practice (from 62 to 25 min for unilateral hernias); (2) more frequent per-operative complications, particularly opening of the peritoneum (28% vs. 3%, P = 0.001); (3) a mean duration of hospitalization significantly (P = 0.05) longer, on average by 1.6 d; (4) a morbidity rate after 30 days significantly higher (16.2% vs. 4.9%, P = 0.01); and, (5) higher costs. There was no significant difference concerning mortality rate (nil), conversion rate (1.5%) and recurrence rate (1.3% vs. 0.6%, non significant). CONCLUSION: Surgical training for laparoscopic treatment of inguinal hernias was associated with a longer operation time and hospital stay, and with higher morbidity and costs. After a good initial training in a teaching hospital, surgeons were capable of performing laparoscopic repair of inguinal hernias with good results.

RESUMEN

Life-threatening accident during anesthesia scarcely happen but the consequences may be dramatic. We report our experience of an allergo-anesthesia consultation created since 1985 in Nice hospital. 452 patients have been investigated: 1) 109 for life-threatening anaphylactic and anaphylactoid drug reactions. They have been investigated by: skin tests intradermal reactions (IDR) and prick tests with substances used during anesthesia (drugs and latex) and for all the muscle relaxants; the radioabsorbent test (RAST) for the muscles relaxants, propofol and latex; the human basophilic degranulation test (HBDT) for all the other drugs. We used the imputability decision table to classify the reactions. When anaphylaxis diagnosis was established (14) an "allergy card" was given to patients which identified the drugs to which they had a positive reaction. 62 patients have presented an anaphylaxis: 57 due to muscle relaxants (37 due to suxamethonium), 4 to latex and 1 to a gelatin. Patients were subsequently contacted and 50 of the 58 have responded. 18 of these patients have received 22 new anesthesias. Without exception, the advises to avoid a drug have been followed, 17 patients have a positive reaction to a muscle relaxant. In four of these, another muscle relaxant (skin test negative) was used without any trouble. For the other 13 who had shown a cross reactivity, all the muscle relaxants had been rejected and another anesthetic technique have been used: local anesthesia (3 cases), epidural (2 cases) associated or not with narcotics (propofol, midazolam), general anesthesia (propofol, midazolam, droperidol, phenoperidine). These drugs were all skin test negative.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

Because pruritus, erythema and tachycardia are observed in some patients during chemonucleolysis, a prospective study was designed to investigate the plasma levels of histamine and catecholamines occurring after an injection of chymopapain. Thirteen patients (11 men and 2 women), mean age 38 +/- 11 years, were studied. They all had negative prick skin tests, human basophil degranulation tests (HBDT) and radio-absorbent tests (RAST) to chymopapain. The patients were premedicated with 100 mg hydroxyzine and 3 g tranexamic acid. Sedation was carried out using 0.1 mg.kg-1 droperidol and 0.02 mg.kg-1 phenoperidine. The nucleosus pulposus was visualized with 3 ml of contrast medium (lopamiron 300); 2 ml of chymopapain were then injected. Blood samples were obtained at T1 (after the contrast medium, but before the chymopapain), and then 5, 10, 15, 20 and 30 minutes after the chymopapain. The usual haemodynamic parameters were recorded at the same times. Four patients had clinical signs (group I), whereas the other nine (group II) did not. There was an increase in histamine levels in three patients from group 1, as well as in two in group II (up to 33 nmol.l-1). However, mean histamine and catecholamines levels were comparable in both groups at all times, and between times, of sampling. There therefore was no relationship between clinical signs and the release of histamine or catecholamines. The premedication with an antihistamine may have protected the patients, but the signs reported by four patients may also be due to the chymopapain itself.

RESUMEN

Following two cases of anaphylactoid reactions during anaesthesia, immunoallergological investigations showed up the responsibility of droperidol, which probably acted by way of an anaphylactic mechanism. In both cases, there were no cardiovascular signs, the main clinical symptom being bronchospasm. The exceptional nature of allergic accidents due to neuroleptic drugs, as opposed to extrapyramidal phenomena, must be underlined. However, these reactions should cast doubts on the safety and usefulness of neuroleptanalgesia.

RESUMEN

Four patients were studied following an anaphylactoid accident occurring during general anaesthesia. Histamine release was assessed on clinical signs, basophil degranulation and, in one case, an early serum histamine peak. Past medical history revealed previous allergies in all cases. An immunological study showed that IgE, CH50, C3 and C4 serum levels were within the normal range. Skin reactivity to histamine was normal in all but one case. In every case, one of the drugs used during the anaesthetic gave a positive skin test and was considered as the causative agent. There were discrepancies between the in vitro and in vivo tests of basophil degranulation, a second drug being positive in one case, and several drugs inducing abnormal degranulation reactions in the other cases. The drugs considered as involved in these accidents are noteworthy: suxamethonium (two cases), fluid gelatin (Plasmion) and droperidol. The results are discussed by the authors.
