Bougie insertion: A common practice with underestimated dangers.

INTRODUCTION: Esophageal perforation after bariatric operations is rare. We report two cases of esophageal perforation after bariatric operations indicating the dangers of a common practice - like insertion of esophageal tubes - and we describe our management of that complication. PRESENTATION OF CASE: A 56 year old woman who underwent laparoscopic sleeve gastrectomy and a 41 year old woman who underwent laparoscopic adjustable gastric banding respectively. In both operations a bougie has been used and led to esophageal perforation. DISCUSSION: The insertion of bougie and especially of inflated bougie is a common practice. It is an invasive procedure that in most cases is performed by the anesthesiologist team. CONCLUSION: Bougie insertion is an invasive procedure with risks and should always be attempted under direct supervision of surgical team or should be inserted by a surgeon.

A simplified technique for translaryngeal tracheostomy (TLT). A preliminary report.

OBJECTIVE: In this prospective observational study we present preliminary results of a modification of the translaryngeal tracheostomy technique that was introduced by Fantoni in 1997. The study was conducted in a five-bed surgical intensive care unit of a university teaching hospital. PATIENTS AND METHODS: The study included 14 consecutive surgical patients (8 men, 6 women) who underwent a modified translaryngeal tracheostomy in a 6-month period. In our modification of the technique, we keep the basic principle of the inside-to-outside approach of the Fantoni technique, and combine it with a blind needle insertion, as reported in the classic subcricoid retrograde intubation technique. The technique that we use involves two medical doctors and a nurse. RESULTS: Mean patient age was 68.9 years (range: 31-85 years) and mean APACHE II score was 15.8 (range: 6-31). Mean operative time for the procedure was 15.2 min (range: 11.5-22 min). Eight of the patients died during the postoperative course in the ICU from causes relevant to their surgical pathology. One patient survived to be discharged from the ICU but died of an acute myocardial infraction later in the same hospital stay. Five patients survived to be discharged from the hospital. CONCLUSIONS: The modified translaryngeal tracheostomy seems to be as reliable and safe as the original technique. In addition, the modified technique is faster and can be performed without the use of an endoscope.

Early symptomatic recurrence after intestinal resection in Crohn's disease is unpredictable.

OBJECTIVE: To identify predictors of early symptomatic recurrence of Crohn's disease (CD) after surgical resection. METHOD: We studied a cohort of 128 patients who had undergone at least one intestinal resection for CD. Factors that might predict early recurrence were documented for analysis using a standardized pro forma. These comprised age, gender, family history, extra-intestinal manifestations, smoking, complicated disease at first presentation, site of disease, preoperative inflammatory markers, involvement of resection margins, orientation and method of anastomosis and postoperative medical therapy. All symptomatic recurrences were confirmed by endoscopic, radiological, or operative means. We defined early recurrence as that which occurred within 36 months of first surgery. Univariate analysis was conducted to compare the distribution of each factor in those who developed early recurrence (n = 48) and those who remained disease free for the first 36 months (n = 50). RESULTS: Of the 128 patients studied, 98 fulfilled the inclusion criteria of at least 36 months of follow up. Of these patients, 48 (49%) patients developed recurrence. Trends towards fewer early recurrences were seen in patients with colonic disease (33%vs 56%, P = 0.068). Of the current smokers, 60% developed early recurrence compared with 43% of nonsmokers (P = 0.269). All other factors examined were similarly distributed between the two groups. Metronidazole as adjuvant treatment does not appear to protect against early symptomatic recurrence. CONCLUSION: This study shows that early symptomatic postoperative recurrence of CD remains unpredictable. Against expectation, abstinence from smoking and postoperative adjuvant metronidazole did not appear to protect against early symptomatic recurrence.

Refractory septic shock: efficacy and safety of very high doses of norepinephrine.

The aim of this study was to evaluate the safety, efficacy, and effects of administration of very high doses of norepinephrine (> 4 microg kg(-1) min(-1)) in catecholamine-resistant septic shock. We reviewed the charts of all patients with nonresponding to commonly used norepinephrine doses (< or = 4 microg kg(-1) min(-1)) septic shock from January 1999 to December 2002 in our Surgical Intensive Care Unit. All patients were treated with high norepinephrine doses (> 4 microg kg(-1) min(-1)), after initial resuscitation, so as to achieve a mean arterial pressure higher than or equal to 65 mmHg. During this 4-year period, 12 consecutive patients with catecholamine-resistant septic shock were included in our study. When compared with the values obtained prior to the administration of very high norepinephrine doses, the values of mean arterial pressure (p = 0.003) and systemic vascular resistance (p = 0.002) significantly increased after the administration of such doses, and additionally, lactate concentrations (p = 0.003) decreased. In contrast, no significant changes were observed regarding mean central venous pressure, pulmonary capillary wedge pressure, and pulmonary arterial pressure. Administration of high norepinephrine doses in our patients resulted in a survival rate of 33.4%. Management of catecholamine-resistant septic shock patients poses a challenging problem. Administration of very high norepinephrine doses is safe and effective and may improve survival of these patients with otherwise extremely high mortality rates.

Gallbladder-duodenal fistula presenting with liver abscess and upper gastrointestinal bleeding.

BACKGROUND: Bilio-enteric communications leading to liver abscess formation are encountered rarely and are therefore not easily suspected by the attending physician. CASE OUTLINE: A bilio-enteric communication involving the gallbladder and the duodenum presented as a septic event with upper gastrointestinal bleeding in a 71-year-old man who was wrongly thought to have undergone a previous cholecystectomy. A pyogenic bacterial liver abscess developed from the fistula in the absence of biliary obstruction. The patient was treated surgically with disconnection of the fistula and drainage of the abscess. DISCUSSION: The liver abscess presumably arose as a consequence of contamination of the bile via the cholecysto-duodenal fistula. The previous operation is likely to have been a simple cholecystostomy.

Implantation of microballoons in the management of fecal incontinence.

PURPOSE: The implantation of expandable microballoons has proved successful for the treatment of stress urinary incontinence. This led us to test its effectiveness in the treatment of severe fecal incontinence. METHODS: Six patients (four male), of average age of 43 (range, 29-60) years, with severe fecal incontinence, underwent implantation of expandable microballoons in the submucosa of the anal canal. The implantation was performed under intravenous sedation as an outpatient procedure. Anal manometry, endosonography, and incontinence assessment with a scoring system were performed before and after the implantation. RESULTS: With a mean follow-up of 8.6 (range, 7-12) months, the incontinence scores improved in all patients from an average of 16.16 (standard deviation: +/- 1.6) before the implantation to an average of 5 (standard deviation: +/- 1.26) after the procedure. The anal pressure at rest was not improved in any patient (mean: 50.16 before treatment to a mean of 53 after treatment). No significant adverse events were associated with the procedure, and no serious postimplantation complications were noted. DISCUSSION: Anal implantation of expandable microballoons seems to be a simple, safe, and effective method that restores the fecal continence without hindering normal defecation.

Endoscopic implantation of Plexiglas (PMMA) microspheres for the treatment of GERD.

BACKGROUND: A gelatinous implant containing polymethylmethacrylate (PMMA) beads is successfully used to augment the diminished thickness of the chorium in patients with skin defects and wrinkles. The aim of the present study was to determine whether submucosal injection of PMMA microspheres into the lower esophageal folds decreases the severity of symptoms and acid reflux in patients with GERD. METHODS: Endoscopic submucosal implantation of PMMA was carried out in 10 patients with GERD who were either refractory to or dependent on proton pump inhibitors. Symptom severity score, 24-hour pH monitoring, upper GI endoscopy, and EUS were performed to evaluate the efficacy of implantation. RESULTS: A significant decrease in the symptom severity score and mean total time with esophageal pH less than 4 was noted after the implantation of PMMA (p < 0.05). Seven of 10 patients were taking no medication after PMMA implantation. There were no serious procedure-related complications. CONCLUSIONS: Endoscopic implantation of PMMA into the submucosa of the lower esophageal folds may be a new method for treating GERD. Further studies are required to determine the long-term efficacy of the procedure.
