Inflammation affects sufentanil consumption in ulcerative colitis.

BACKGROUND: Previous studies have demonstrated an increased perioperative opioid requirement during inflammatory disease. To evaluate the influence of the inflammatory process, we studied in the same patient the sufentanil requirement during procedures that occur during two distinct phases of ulcerative colitis with different inflammatory profiles: (1) left colectomy for major colitis unresponsive to medical treatment during acute inflammation and (2) coloprotectomy with ileoanal anastomosis, three months after recovery of the acute inflammatory episode. METHODS: Sixteen patients with clinical and histological evidence of ulcerative colitis scheduled for colectomy with ileoanal anastomosis were included. For each surgical procedure, anaesthesia was induced with sufentanil 0.5 microg kg(-1) and propofol 2 mg kg(-1). Patients were ventilated with 50% nitrous oxide and oxygen, and tidal volume was adjusted to keep end-tidal CO2 at 30 mmHg. Anaesthesia was maintained with end-tidal isoflurane at 0.5%. Analgesia was achieved with continuous infusion of sufentanil at 0.3 microg kg(-1) h(-1). Additional boluses of sufentanil and increases in infusion rates were used when haemodynamic variables increased to more than 20% of preoperative values. Sufentanil consumption during surgery was analysed by Wilcoxon signed rank sum test. P < 0.05 was considered significant. RESULTS: Total intra-operative sufentanil requirement was significantly larger during colectomy performed for acute inflammatory colitis than during ileoanal anastomosis performed after the inflammatory process (1.24 +/- 0.48 microg kg(-1) h(-1) vs. 0.62 +/- 0.3 microg kg(-1) h(-1); P < 0.05). CONCLUSION: For the same patient, inflammatory status influences opioid requirements during surgery for ulcerative colitis.

[Pituitary apoplexy: a rare complication in the postoperative period]. / Apoplexie hypophysaire: complication postopératoire rare d'une chirurgie réglée.

Postoperative pituitary apoplexy is an exceptional but life-threatening complication. We report the case of a 62-year-old man who underwent a cystoprostatectomy under general anaesthesia. The immediate postoperative course was complicated by asthenia and an altered state of consciousness. A few days later, a homonymous followed by bitemporal hemianopia developed. A CT-scan and magnetic resonance imaging made the diagnosis o pituitary apoplexy. The treatment was a medical one, with rapid improvement in the patient's condition.

[Duodenocaval fistula: an unusual form of peptic ulcer revelation]. / Fistule duodénocave: mode de révélation inhabituel d'un ulcère duodénal.

The duodenocaval fistula is exceptional. We report the case of a 44-year-old patient with duodenocaval fistula. The patient had no history of peptic ulcer disease. The clinical feature was firstly a septic shock and then an haemorrhagic shock. Only laparotomy confirmed the diagnosis. The treatment was a surgical one with a rapid improvement. The prognosis depends on surgical experience and remains serious.

[Colon hernia through a defect in the iliac crest after bone graft harvesting] . / Hernie colique à travers la fenêtre osseuse d'une prise de greffon iliaque.

A case of a patient with an hernia through a defect in the iliac crest after bone graft harvesting is described. The osseous defect provides a rigid ring against which repeated sudden elevations in abdominal pressure can result in disruption of soft tissue and herniation of abdominal contents. Standard plain radiographs and barium studies are of limited interest and may even be misleading in diagnosing the herniation. Findings on computed tomography led to detection of this abnormality, and should be the first line exam in these cases.
