[Versatility of the microvascular fibular flap in limb reconstruction]. / Versatilidad del colgajo microvascular de peroné en reconstrucción de extremidades.

BACKGROUND: The structural characteristics of the fibula, strength, shape, length and limited donor site morbidity make it more suitable for reconstructing long bone defects larger than 6cm in the limbs. MATERIAL AND METHODS: A descriptive study was conducted using a non-probabilistic sample of consecutive cases undergoing on limb reconstruction with free fibular flap in the period from January 2010 to January 2015 in the Mexican Institute of Social Security No. 21, Monterrey Nuevo Leon. RESULTS: The mean age of the ten cases included was 25 years, with the most common diagnosis being trauma in 4 patients, osteosarcoma in 2, followed by one congenital pseudoarthrosis of the tibia, one non-union fracture, and one gunshot wounds, respectively. The most common location was tibia, followed by humerus, radius, ulna and femur. CONCLUSIONS: This study has shown that the fibular free flap can be an excellent option for management of long bone defects, regardless of cause of the injury. One or more skin islands can be added for coverage in exposure of deep tissue and osteosynthesis material, thus preserving the septocutaneous perforators.

[Surgical treatment of hemorroids with rectal mucosal resection using a stapler]. / Mucosectomía rectal con engrapadora para el tratamiento quirúrgico de la enfermedad hemorroidal: estudio prospectivo de 160 pacientes.

OBJECTIVE: To analyze the results of Longo stapled mucosectomy for hemorrhoidal disease in a 1 to 3 years follow up. PATIENTS AND METHODS: Clinical response and complications where analyzed in patients treated for grade II to IV non-complicated hemorrhoidal disease with Longo stapled hemorrhoidectomy. RESULTS: In a 27 months period, 160 patients were treated (105 men and 55 women), mean age was 44.1 years (range: 24 to 72 years), and 110 patients had grade III hemorrhoid disease. Non procedure complications were noted, early complications were detected in 5% of patients and late complications were detected in 10% of patients. In a mean follow-up of 18.8 months, 82.5% of the patients remained asymptomatic and 94.4 of the patients reported a good satisfaction score. A second surgery was required in three patients because of recurrence. CONCLUSION: Longo stapled mucosectomy is a safe treatment for non complicated hemorrhoid disease. In a 18 month follow up most patients were asymptomatic.

Prospective study of factors affecting postoperative pain and symptom persistence after stapled rectal mucosectomy for hemorrhoids: a need for preservation of squamous epithelium.

PURPOSE The purpose of the study was to determine the variables associated with postoperative pain and the clinical response of patients with uncomplicated hemorrhoidal disease treated with stapled rectal mucosectomy in the medium term. METHODS Patients with Grade II to IV, uncomplicated hemorrhoidal disease who underwent stapled rectal mucosectomy were prospectively included. The basal characteristics of the population were evaluated and level of stapling and placement of hemostatic suture determined. Histologically, the type of resected epithelium and presence of muscle fibers was evaluated. Postoperative pain was evaluated by means of a visual analog scale. Complications and clinical response were evaluated. RESULTS One hundred patients with a mean age of 43.9 years were included. Only columnar epithelium was resected in 48, transitional epithelium in 47, and squamous epithelium in 5 patients. Smooth muscle fragments were found in 55 patients, and, in 12 of these, fibers from the external muscular layer of rectum were also seen. Follow-up was 12.6 +/- 3.4 (range, 7-24) months. A total of 79 patients were completely asymptomatic at the end of follow-up. Resected squamous epithelium was associated with a higher postoperative pain level in the multivariate analysis (coefficient beta = 1.16 (95 percent confidence interval, 0.08-2.24); P = 0.035). CONCLUSIONS Rectal mucosectomy with stapler is an effective method for the treatment of uncomplicated prolapsing hemorrhoidal disease. Intensity of postoperative pain was associated with the type of resected epithelium. This suggests that low transection of hemorrhoids must be avoided.

Rigid rectosigmoidoscopy: still a well-tolerated diagnostic tool.

BACKGROUND: Although rigid rectosigmoidoscopy has been gradually replaced by the use of flexible rectosigmoidoscopy in recent years, it remains an effective, economic and widely available diagnostic tool. The aim of this study was to determine the type and magnitude of symptoms during rigid rectosigmodoscopy. METHODS: Prospective evaluation of patients who underwent diagnostic rigid rectosigmoidoscopy. The main complaints were recorded, and their magnitude quantified using a visual analogue scale. RESULTS: A total of 134 patients (mean age = 48 years) were examined. The prone jackknife position was used in 54% of them and left lateral decubitus in 46%. A complete (full length) examination was achieved in 68%. There were no complications. Sixty percent of patients referred complaints: pain (33%), discomfort by rectal preparation (13%), uncomfortable defecation desire (8%), and discomfort by the position (4%). Median values determined by visual analogue scale for pain, discomfort by rectal preparation, uncomfortable positioning and overall discomfort were graded as 3.3, 3.3, 2.1 and 2, respectively. There was an association between higher magnitude of pain and overall discomfort with female gender, left lateral decubitus position, and full-length exploration (p < 0.05). CONCLUSION: A high percentage of patients have symptoms during rigid rectosigmoidoscopy but the study is usually well tolerated due the low magnitude of pain and discomfort and remains a very cost-effective study.

Stapled rectal mucosectomy vs. closed hemorrhoidectomy: a randomized, clinical trial.

INTRODUCTION: We compared the safety and clinical outcome between stapled rectal mucosectomy and closed hemorrhoidectomy for the surgical treatment of noncomplicated hemorrhoidal disease. METHODS: Eighty-four patients with Grade III and IV hemorrhoidal disease were randomly assigned to two groups: 1) stapled rectal mucosectomy group (n = 42) and 2) closed hemorrhoidectomy group (n = 42). Postoperative pain, analgesic use, symptoms, disability, early and late complications, and patient satisfaction were evaluated, among others. Follow-up was six months. RESULTS: Eighty-four patients, averaging 45 +/- 9 years of age, underwent surgery. Two were lost to follow-up. Length of surgery and disability, postoperative pain, and use of analgesics were significantly less for patients in the stapled rectal mucosectomy group. In the closed hemorrhoidectomy group early complications were more frequent but not statistically significant, and there were no statistically significant differences regarding the frequency of late complications. No serious complications were reported in either group. Closed hemorrhoidectomy proved to be superior for bleeding control (95.1 percent closed hemorrhoidectomy 80.5 percent stapled rectal mucosectomy; P= 0.04). Patient satisfaction was similar in the two groups, but stapled rectal mucosectomy patients were more willing to undergo the same procedure (P = 0.02). CONCLUSION: Both stapled rectal mucosectomy and closed hemorrhoidectomy are safe procedures. Closed hemorrhoidectomy was superior for bleeding control in Grade III and IV hemorrhoidal disease, but more painful and disabling than stapled rectal mucosectomy.
