Strangulated ileal trans-coloanal-anastomotic hernia: a complication of Altemeier's procedure previously never reported.

A postoperative complication after Altemeier operation, so far never reported, is described in a 42 years old mentally disabled patient with external full thickness rectal prolapse who usually had prolonged straining at defecation. After 6 d from perineal rectosigmoidectomy, the patient, was discharged free of complications. Four days later he was readmitted in emergency for strangulated perineal trans-anastomotic ileal hernia that occurred at home during efforts to defecate. The clinical feature required an emergency operation for repositioning the ileal loops into the abdomen, resection of the necrotic ileum, and end colostomy. The outcome of the second operation was free of complication and the patient was discharged on the 6(th) postoperative day. In conclusion, after Altemeier operation prolonged straining at defecation should be carefully avoided.

Catheter-related complications in long-term home parenteral nutrition patients with chronic intestinal failure.

BACKGROUND: Home Parenteral Nutrition is a therapeutic option to improve quality of life in chronic intestinal failure. AIMS: To describe frequency of complications both in cancer and noncancer patients. METHODS: This study was performed on 270 adult patients (52% with cancer, 48% without cancer) followed for a total of 371 years of treatment. Mean duration of therapy was 191±181 for cancer and 830±1168 days/patient for noncancer. The treatment was administered by a competent, dedicated provider. Patients received our prescribed "all-in-one admixtures" at their homes. RESULTS: Catheter-related complications/1000-days-catheter was 1.40; mechanical complications were comparable in cancer (0.82) and noncancer (0.91) patients while a statistically significant difference was observed between cancer (0.71) and noncancer (0.46) patients for sepsis. Bacterial infections were more frequent in noncancer, mycotic infections primarily affected cancer patients. In our experience 49% of the patients were readmitted, with a low incidence rate of 0.89/1000 days-catheter. The incidence of hepatobiliary complications in our population was 65%. The degree of liver damage was related to short bowel syndrome and to length of treatment. CONCLUSIONS: This study indicated that cancer patients are more vulnerable to CVC-related infections during Home Parenteral Nutrition and that a safer Home Parenteral Nutrition protocol should be adopted in order to contain CVC-related complications.

Cholestasis induced by total parenteral nutrition.

Parenteral nutrition is a life-saving treatment for patients who have acute and chronic intestinal failure. Severe cholestasis induced by total parental nutrition (TPN-IC) is characterized by bile duct regeneration, portal inflammation, and fibrosis. Its progression could be very rapid, and in some patients liver cirrhosis may develop in few months. This article describes the definition, incidence, hepatic changes, histopathologic findings, risk factors, pathogenesis, and clinical implications of TPN-IC. The goal is to improve hospital and home management, quality of life, and prognosis of patients requiring parenteral nutrition.

Reliability of electrophysiologic anal tests in predicting the outcome of sacral nerve modulation for fecal incontinence.

INTRODUCTION: Sacral nerve modulation has been demonstrated to be a new efficacious treatment for fecal incontinence. The effectiveness of the procedure is preliminarily tested by means of a peripheral nerve evaluation. Integrity of the sacral neural pathway is generally believed to be a necessary condition for a good response, but no data are available to confirm whether electrophysiologic anal tests are predictive of the clinical outcome of the peripheral nerve evaluation. METHODS: Eighty-two incontinent patients underwent the peripheral nerve evaluation after full evaluation of the anorectal physiology. Univariate analysis was performed, and the positive predictive value, sensitivity, and specificity were calculated for each of the tests. RESULTS: Forty-six patients had successful results to the peripheral nerve evaluation and were subjected to permanent implant of a sacral electrostimulator. Anal sphincter electromyography had been performed in 60 patients, whereas pudendal nerve terminal motor latency had been assessed in 68 and evoked sacral potentials in 29 patients. Anal electromyography was statistically related to the outcome of the peripheral nerve evaluation ( P = 0.0004) with a positive predictive value of 81 percent, a sensitivity of 44 percent, and a specificity of 81 percent. Pudendal nerve terminal motor latency on the right side did not correlate with the outcome, but left pudendal nerve terminal motor latency was weakly correlated ( P = 0.02), although both tests had a low positive predicting value and sensitivity vs. good specificity. Evoked sacral potentials did not correlate with the outcome and had a low positive predictive value, sensitivity, and specificity. CONCLUSIONS: Simple anal sphincter electromyography can predict the outcome of the peripheral nerve evaluation with good positive predictive value and specificity in patients with fecal incontinence. Other, more expensive, electrophysiologic anal tests do not add further prognostic information.

Permanent sacral nerve modulation for fecal incontinence and associated urinary disturbances.

BACKGROUND AND AIMS: Sacral nerve modulation (SNM) using an implantable pulse generator is gaining increasing acceptance in the treatment of several functional disturbances of the urinary and intestinal tract. This new therapeutic approach offers new possibilities in the treatment of fecal incontinence (FI) by means of its possible effects on anorectal physiology. PATIENTS AND METHODS: Fourteen patients with FI, six of whom had associated urinary disturbances, underwent permanent SNM after successful peripheral nerve evaluation tests. All had a clinical evaluation including FI grading systems (American Medical systems, AMS; Continence Grading System, CGS) and quality of life questionnaires (Fecal Incontinence Quality of Life, FIQL), and anorectal physiology tests performed before and during electrostimulation. Two patients had a lead displacement which was repositioned. Median follow-up was 14 months (range 6-48 months). RESULTS: AMS scores decreased significantly from 101 to 67 after 24 months CGS scores from 15 to 2 after 2 months. The median number of episodes of major incontinence per 2 weeks decreased from 14 to 1 after 24 months. FIQL scores improved significantly in the nine patients tested from an overall score of 1.59 to 3.3, with improvement in all areas of the FIQL. Four of the six patients with associated urinary disturbances had a significant improvement in their symptoms. Anal resting and squeezing tone did not change significantly, nor did rectal volumetry, compliance, rectoanal inhibitory reflex, or length of the anal high-pressure zone, while 24-h rectal manometry showed inhibition of the spontaneous rectal motility complexes after meal and on awakening in the only two patients undergoing this investigation. CONCLUSION: Although the mechanism of action of SMN is still unclear and requires further investigations, clinical results are very encouraging, confirming the role of this new and safe procedure in the treatment of FI and associated urinary disturbances.

Pancreatic rupture following a bull-head caused blunt abdominal trauma.

A 33-year-old man was admitted to our hospital with clinical and instrumental-diagnostic evidence (CT) of haemoperitoneum following a blunt abdominal trauma due to being butted by a bull. A full-thickness rupture of the pancreas, at the level of the isthmus, was found at laparotomy. The emergency procedure consisted in evacuation of the haemoperitoneum, haemostasis and suture of the pancreatic lesion plus drainage of the lesser sac. A high-output (800 ml/day) post-traumatic pancreatic fistula developed in the following days, with the need for a second operation. In the presence of a large pancreatic defect extensively communicating with the Wirsung duct, a singular surgical procedure was adopted in the form of a Roux-en-Y pancreaticojejunostomy with catheterisation of the pancreatic fistula using a small disposable silicone catheter. The post-operative course was uneventful and healing of the pancreatic fistula was documented at CT scan 39 days after the operation.
