Dynamics of albumin synthetic response to intra-abdominal abscess in patients with gastrointestinal fistula.

BACKGROUND: Low serum albumin concentration is a predictor of failure of source control for intra-abdominal infection. However, data on dynamics of albumin synthesis in these patients and to what extent these changes contribute to hypoalbuminemia are relatively scarce. We investigated in a group of patients with gastrointestinal fistula the dynamic response of liver albumin synthesis to intra-abdominal abscess and how these related to hypoalbuminemia and circulating endocrine hormone profiles. METHODS: Eight gastrointestinal fistula patients scheduled to undergo percutaneous abscess sump drainage were enrolled prospectively to measure albumin synthesis rates at different stages of the inflammatory response (immediately after diagnosis and 7 d following sump drainage when clinical signs of intra-abdominal sepsis had been eradicated). Eight age-, sex-, and body mass index-matched intestinal fistula patients were studied as control patients. Consecutive arterial blood samples were drawn during a primed-constant infusion (priming dose: 4 micromol·kg(-1), infusion rate: 6 micromol·kg(-1)·min(-1)) to determine the incorporation rate of L-[ring-(2)H5]-phenylalanine directly into plasma albumin using gas chromatography/mass spectrometry analysis. RESULTS: Patients suffering from intra-abdominal infection had reduced plasma albumin and total plasma protein concentrations, compared with control patients. Albumin fractional synthesis rates in patients with intra-abdominal abscess were decreased, compared with those in the control group. When the source of infection was removed, albumin synthesis rates returned to control values, whereas albumin concentrations did not differ significantly from the corresponding concentrations in control subjects and patients with intra-abdominal abscess. CONCLUSION: Despite nutritional intervention, albumin synthesis rate is decreased in intestinal fistula patients with intra-abdominal abscess; albumin synthesis returns to control values during convalescence.

[Postnecrotic cysts of the pancreas: possible ways of minimally invasive external and internal drainage].

The authors have shown a possibility of minimally invasive interventional surgery in treatment of postnecrotic cysts of the pancreas and their complications. The most optimal accesses for drainage of the cavities located inside the body and the pancreas head are determined. The use of the methods of internal drainage of the cyst cavity connected with the main pancreatic duct allowed avoidance of open operations. The results of antegrade percutaneous or transcavital as well as retrograde endoscopic restoration of the patency of the main pancreatic duct in treatment of the pancreatic cysts connected with the duct system are shown.

Current role of surgery in the treatment of digestive fistulas.

UNLABELLED: Surgery is the main treatment of digestive fistulas (DF) but its role has changed over the last 40 years. The aim of this review is to analyze the surgical management of DF paying attention to timing and type of surgery. METHODS: We performed a review considering the following electronic databases: Medline, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, EMBASE and the reference lists of the key papers. Literature searches were carried out using the following medical subject headings: "digestive fistula"; "gastrointestinal fistula"; "enterocutaneous fistula"; 'AND surgery"; "AND surgical treatment". Because the absence of randomized studies, we have considered the larger series or original techniques. RESULTS: Surgical treatment of DF has two indications: to treat complications due to DF juice action such as peritonitis, abscesses, gangrene, bleeding; and when a fistula fails to heal. In this case the surgical indication is often difficult to establish, because of the risk of making an inconclusive act. CONCLUSIONS: Indications to surgery, timing and choice of operation cannot often be standardized because they depend on a mixture of DF and patient characteristics. In specific cases, involvement of nutritionist and plastic surgeon is required.

Fistula in ano surgery has no impact on pudendal nerve terminal motor latency.

BACKGROUND: Anal fistula surgery is recognized as a major risk factor for anal incontinence. This incontinence is mainly due to surgical sphincter lesions, although a neurogenic mechanism through damage to the pudendal nerve is not excluded. The objective of our study was to evaluate the influence of anal surgery on the anal terminal motor latency of the pudendal nerve (PNTML). MATERIALS AND METHODS: The PNTML values were measured pre- and postoperatively, respectively, in 33 patients (28 men, 5 women) treated for anal suppuration and 34 patients (21 men, 13 women) undergoing pedicular hemorrhoidectomy using the Milligan and Morgan technique. RESULTS: The average age was 49.6 years in the hemorrhoid group and 45 years in the fistula group (p=0.19). There was no difference in the sex ratio between the two groups (p=0.06). In the anal fistula group, the preoperative mean PNTML was 2.42 (+/-0.46) ms on the infected side and 2.40 (+/-0.42) ms on the healthy side, with a significant difference from the control group's preoperative ipsilateral latencies: 2.73 (+/-0.60) ms (p=0.02, p=0.01). The variations in the postoperative PNTML of the fistula group, both on the healthy side (DeltaPNTML=0.06+/-0.42 ms) and on the diseased side (DeltaPNTML=0.03+/-0.40 ms), are comparable with those of the hemorrhoid group (DeltaPNTML=0.01+/-0.48 ms; p=0.63, p=0.84). CONCLUSION: The nervous conduction of the pudendal nerves does not seem to be altered by the presence of an infectious process in the ischiorectal fossa nor by the surgical procedure. However, a more refined electrophysiological study would seem to be necessary to assess the repercussions on the perineal innervation.
