Surgical Management of Fistula-in-ano Among Patients With Crohn's Disease: Analysis of Outcomes After Fistulotomy or Seton Placement-Single-Center Experience.

BACKGROUND AND AIM: Fistula-in-ano is a common problem among patients with Crohn's disease and carries significant morbidity. We aimed to study the outcomes of surgical treatment of fistula-in-ano after fistulotomy or seton placement in patients with perianal fistulizing Crohn's disease. MATERIAL AND METHODS: A retrospective observational study of 59 patients diagnosed with Crohn's disease, who were treated surgically for fistula-in-ano between 2010 and 2014 in our department. The assessment of disease complexity included a detailed physical examination, magnetic resonance imaging of the rectum, and examination under anesthesia. Outcomes for analysis included wound healing rate and postoperative incontinence. RESULTS: High transsphincteric fistula was found in 44% of the patients, while mid or low transsphincteric fistulas were found in 51%. Three women (5%) had a rectovaginal fistula. All patients with high transsphincteric fistulas were treated with loose seton placement. Patients with mid- or low-level transsphincteric fistula were offered either fistulotomy or seton placement based on the clinical evaluation. The mean follow-up duration was 1.6 ± 1.1 years. In terms of recurrence, one patient treated with seton placement presented with recurrence 6 months after seton removal and one patient with fistulotomy failed to achieve wound healing. Minor incontinence was found in six patients treated with fistulotomy and in three patients treated with seton placement; however, this difference was not significant (chi-square = 1.723, df = 1, Monte-Carlo: p = 0.273). CONCLUSION: Fistulotomy could achieve good results in terms of wound healing and incontinence in strictly selected patients with Crohn's disease suffering from low-lying transsphincteric fistulae. For more high-lying or complicated fistulae, seton placement is more appropriate. For high transsphincteric fistulae, the only option is placement of loose seton.

Long-term results with the modified Sugiura procedure for the management of variceal bleeding: standing the test of time in the treatment of bleeding esophageal varices.

BACKGROUND: The surgical approaches to the treatment of bleeding esophageal varices in cirrhotic patients have been reduced since the clinical development of endoscopic sclerotherapy, transjugular intrahepatic portosystemic shunt (TIPS), and liver transplantation. However, when acute sclerotherapy fails, and in cases where no further treatment is accessible, emergency surgery may be life saving. In the present study we retrospectively analyzed the results of the modified Sugiura procedure, performed as emergency and semi-elective treatment in the patient with bleeding esophageal varices. METHODS: Ninety patients with cirrhosis and portal hypertension were managed in our department for variceal esophageal bleeding between January 1985 and December 1992. The modified Sugiura procedure was performed in 46 patients on an emergency (25 patients) or semi-elective (21 patients) basis. Liver cirrhosis stage according to Child classification was A in 4 patients, B in 16 patients, and C in 26 patients. RESULTS: Acute bleeding was controlled in all patients. Postoperative mortality was 23.9% (11 of 46 patients). The mortality rate was 34.6% in Child class C patients (9 of 26 patients), and 12.5% in Child class B patients (2 of 16 patients). Twenty-four patients had long-term follow-up extending from 14 months to 22 years (mean 83.1 months). Ten of 24 patients (41.6%) did not develop rebleeding for 5-22 years (mean 10.3 years). Overall 5-year survival in these 24 patients was 62.5%. CONCLUSIONS: The modified Sugiura procedure remains an effective rescue therapy for patients with bleeding esophageal varices when alternative treatments fail or are not indicated. Moreover, it can be a life-saving procedure in patients with anatomy unsuitable for shunt surgery or for patients treated in nonspecialized centers where surgical expertise for a shunt operation is not available.

Effect of collagen powder on lymphorrhea after modified radical mastectomy. A randomized controlled trial.

AIM: Postoperative lymphorrhea is a major complication of axillary lymphadenectomy. The aim of our study was to evaluate the impact of type I collagen in postoperative lymphorrhea in mastectomy patients. METHODS: Eighty patients that underwent modified radical mastectomy for breast cancer were randomized in two groups. In group A (collagen group, n = 42) collagen type I (Cellerate RX powder) was applied in the axillary cavity after lymphadenectomy while in group B (control group, n = 38) lymphadenectomy was performed in the standard fashion without the use of a sealant. Suction drains remained in place until the daily amount of lymphatic drainage fell under 30 ml. The total amount and the duration of drainage, as well as the morbidity and severity of arm pain were compared in the two groups. RESULTS: There was a non significant trend towards lower overall drainage in the collagen group. The duration of drainage and postoperative pain were similar in the two groups, as was morbidity. Subgroup analysis of patients according to the number of lymph nodes excised, revealed significantly less lymphorrhea in terms of volume and duration in patients who had more than ten lymph nodes excised. CONCLUSION: Collagen type I (Cellerate RX powder) appears to attenuate postoperative lymphorrhea in patients undergoing axillary lymphadenectomy especially when > 10 lymph nodes are removed.

Extraovarian peritoneal serous papillary carcinoma mimicking colonic obstruction.

Involvement of the colon by extraovarian peritoneal serous papillary carcinoma (EPSPC) is considered as rare. During a 10-year period the records of five female patients with a mean age of 73.4 years who were admitted for colonic obstruction due to EPSPC were reviewed. Preoperative and postoperative data were studied. All patients presented with symptoms of colonic obstruction and high concentrations of CA-125. Involvement of the sigmoid colon was demonstrated preoperatively both in CT and colonoscopy. Operative findings of multiple peritoneal implantations involving the surface of the ovaries in two cases, the greater omentum in three cases and invasion of the sigmoid colon in all cases prompted us to perform sigmoidectomy and omentectomy in all cases with bilateral salpingo-oophorectomy in four of them. All patients received adjuvant paclitaxel plus platinum-based combination chemotherapy.

Urgent thyroidectomy for acute airway obstruction caused by a goiter in a euthyroid pregnant woman.

Pregnancy constitutes a significant factor for thyroid enlargement. However, acute respiratory failure as a result of airway obstruction from an enlarged thyroid gland is an unusual incident. The case presented here concerns a 27-year-old black woman in her 20th gestational week who underwent an urgent operation for removal of a nontoxic, multinodular, mildly substernal goiter that was causing severe upper airway obstruction leading to acute life-threatening respiratory failure. Diagnosis of an extrathoracic tracheal stenosis was based on spirometry with analysis of the flow volume curve and was confirmed by magnetic resonance imaging of the neck. Despite operational risks to the mother as well as the fetus during gestation, an urgent thyroidectomy was carried out successfully. The postoperative period progressed normally and the patient completed her pregnancy with no further respiratory symptoms.

Experimental isolation and transplantation of hepatocytes with the use of antibody against interleukin-2 receptor (daclizumab) as immunosuppressive agent.

INTRODUCTION: Daclizumab (Dmab) is a genetically engineered humanized IgG1 monoclonal antibody that binds to the alpha chain of the interleukin-2 receptor (Tac, CD25, p55) expressed on activated human T lymphocytes. Dmab has been used in a clinical protocol of islet transplantation with satisfactory results. The aim of the present study was to evaluate the use of an antibody against the interleukin-2 receptor (Dmab) as an immunosuppressive agent in an experimental model of hepatocyte allotransplantation (allo-Tx) in rats with fulminant hepatic failure (FHF). MATERIALS AND METHODS: Six Wistar rats were used as donors and 48 Lewis rats as recipients: four groups of 12 animals each with induction of FHF and 24 hour later hepatocyte Tx--group A: no treatment; group B: cyclosporin (20 mg/kg days 0 to 5 and 10 mg/kg days 6 to 15); group C: Dmab (0.05 mg day of Tx and 0.05 mg day 7); and group D: Dmab and cyclosporine. Hepatocytes were transplanted intrasplenically. Animals were followed for 15 days. RESULTS: Statistical analysis showed better survival among groups C (83%, MST = 13) and D (92%, MST = 14.25) compared to groups A (max 72, MST = 1.5) or B (50%, MST = 9). Survival in group D was better but not significantly than group C. Biochemical evaluation and histology confirmed satisfactory function and engraftment, respectively. CONCLUSION: This experimental model showed the safe, effective use of Dmab.
