Submucous cleft palate is a congenital malformation with specific clinical and anatomical features. It can be present with or without velopharyngeal insufficiency. Surgical treatment of this malformation is indicated only when velopharyngeal insufficiency has been demonstrated. This article compares two modalities of surgical treatment for submucous cleft palate. The first includes a minimal incision palatopharyngoplasty, as described in a previous report. The second combines the first technique with additional individualized velopharyngeal surgery (individualized pharyngeal flap or sphincter pharyngoplasty) performed simultaneously. The individualized part of the procedure was selected and performed according to the findings of videonasopharyngoscopy and multiview videofluoroscopy, as reported previously. Two hundred and three patients with submucous cleft palate were studied from 1990 to 1999. Videonasopharyngoscopy and multiview videofluoroscopy demonstrated velopharyngeal insufficiency in 72 patients, who were randomly divided into two groups. Those in group 1 (n = 37) underwent a minimal incision palatopharyngoplasty. Patients in group 2 (n = 35) also underwent that procedure but simultaneously received individualized pharyngeal flap or sphincter pharyngoplasty, according to the findings of videonasopharyngoscopy and multiview videofluoroscopy. The median age of the patients from both groups was not significantly different (p > 0.5). The frequency of residual velopharyngeal insufficiency after palatal closure was not significantly different in both groups of patients (14 percent versus 11 percent; p > 0.5). The mean size of the gap at the velopharyngeal sphincter during speech was not significantly different in both groups of patients before surgery (23 percent versus 22 percent; p > 0.5). After the surgical procedures, there was a nonsignificant difference between both groups of patients in mean residual size of the gap in cases of velopharyngeal insufficiency (7 percent versus 8 percent; p > 0.5). It seems that minimal incision palatopharyngoplasty is a safe and reliable procedure for palatal closure in patients with submucous cleft palate. The use of additional individualized velopharyngeal surgery performed simultaneously did not seem to decrease the frequency of residual velopharyngeal insufficiency. Moreover, the residual size of the gap at the velopharyngeal sphincter was not significantly reduced when an additional surgical procedure was performed simultaneously with palatal closure. To compare the lateral pharyngoplasty procedure with uvulopalatopharyngoplasty (UPPP) in the treatment of obstructive sleep apnea hypopnea syndrome (OSAHS).
                Prospective randomized study.
                Academic tertiary center.
                Twenty-seven adults with OSAHS originally selected for treatment with UPPP.
                Patients were randomly assigned to 2 groups: in one group, we performed the lateral pharyngoplasty (15 cases), and in the other, we did the UPPP (12 cases).
                We compared treatment outcomes through the evaluation of OSAHS-related symptoms and the analysis of polysomnographic tests and computed tomography measurements of pharyngeal airway. The lateral pharyngoplasty group achieved a statistically greater reduction in body weight, excessive daytime sleepiness, and apnea-hypopnea index. In addition, only in this group did we observe a statistically significant increase in the amount of deep sleep stages and improvement in morning headaches. Patients from the UPPP group did not present significant changes in the polysomnographic parameters. Pharyngeal airway measurement outcomes were similar in both groups and did not reflect the clinical and polysomnographic differences we observed.
                Lateral pharyngoplasty produces better clinical and polysomnographic outcomes in the treatment of OSAHS than does UPPP, without resultant differences in the cross-sectional measurements of the pharyngeal airway between these treatments. In this study, we assessed the efficacy of a new method (expansion sphincter pharyngoplasty [ESP]) to treat obstructive sleep apnea.
                We conducted a prospective, randomized controlled trial.
                Forty-five adults with small tonsils, body mass index less than 30 kg/m2, of Friedman stage II or III, of type I Fujita, and with lateral pharyngeal wall collapse were selected for the study.
                The mean body mass index was 28.7 kg/m2. The apnea-hypopnea index improved from 44.2 +/- 10.2 to 12.0 +/- 6.6 (P < 0.005) following ESP and from 38.1 +/- 6.46 to 19.6 +/- 7.9 in the uvulopalatopharyngoplasty group (P < 0.005). Lowest oxygen saturation improved from 78.4 +/- 8.52% to 85.2 +/- 5.1% in the ESP group (P = 0.003) and from 75.1 +/- 5.9% to 86.6 +/- 2.2% in the uvulopalatopharyngoplasty group (P < 0.005). Selecting a threshold of a 50% reduction in apnea-hypopnea index and apnea-hypopnea index less than 20, success was 82.6% in ESP compared with 68.1% in uvulopalatopharyngoplasty (P < 0.05).
                The ESP may offer benefits in a selected group of OSA patients. Esophagogastrectomy for esophageal cancer is the standard surgical treatment as a curative measure or for palliation. Esophagogastric anastomotic leakage and stricture are common life-threatening postoperative complications (more so if the leakage occurs in the chest), and the success of the anastomosis created in the reconstruction of the resected esophagus can highly influence morbidity and mortality.
                A prospective, randomized study was undertaken on 291 patients treated for carcinoma of the esophagus between January 2004 and December 2008. The study excluded 36 patients (12%) who were inoperable. Patients were assigned to 2 treatment groups that consisted of 128 patients in group A and 127 patients in group B according to a restricted, permuted block randomization plan. Patients in group A underwent an esophagogastrectomy with wrapping of the pedicle omental flap around the esophagogastric anastomosis. Group B patients underwent an esophagogastrectomy with only a stapled technique.
                Of all 255 patients who received an esophagogastric anastomosis, 226 (89%) were discharged from the hospital within 15 days of operation. There was no significant difference between these 2 groups in regard to the incidence of pulmonary complications, abdominal or thoracic infections, and days of hospital stay. Anastomotic leaks occurred in a single patient from group A (1%) and in 7 patients from group B (6%). In group A, 33 patients underwent transhiatal esophagogastrectomy and 95 had thoracic esophagogastrectomy, which resulted in an anastomotic leakage in 1 (3%) and 0 (0%) patients, respectively. In group B, 42 patients had transhiatal esophagogastrectomy and 85 had thoracic esophagogastrectomy, which resulted in anastomotic leakage in 5 (12%) and 2 (2%) patients, respectively. The leakage ratio of group B was significant greater than that of group A (P < .05). Two patients were excluded during the evaluation of the benign stricture due to hospital mortality. Anastomotic strictures were noted in 8 patients from group A (6%) and 20 patients from group B (16%), and the difference in the incidence of anastomotic strictures between these 2 groups was statistically significant (P < .05).
                Wrapping of the pedicle omental flap around the esophagogastric stapled anastomosis site decreases the incidence of anastomotic leakage and stricture rate after esophagectomy for esophageal cancer, thereby decreasing the morbidity and mortality of the procedure.

                A colonic J-pouch may reduce excessive stool frequency and incontinence after anterior resection, but at the risk of evacuation problems. Experimental surgery on pigs has suggested that a coloplasty pouch (CP) may be a useful alternative. Although CP has recently been shown to be feasible in patients, there is no randomized controlled trial comparing bowel function with the J-pouch.
                After anterior resection for cancer, patients were allocated to either J-pouch or CP-anal anastomoses. Continence scoring, anorectal manometry, and endoanal ultrasound assessments were made before surgery. All complications were recorded, and these preoperative assessments were repeated at 4 months. The assessments were repeated again at 1 year, and a quality of life questionnaire was added.
                Eighty-eight patients were recruited from October 1998 to April 2000. Both groups were well matched for age, gender, staging, adjuvant therapy, and mean follow-up. There were no differences in the intraoperative time and hospital stay. CP resulted in more anastomotic leaks. At 4 months, J-pouch patients had 10.3% less stool fragmentation but poorer stool deferment and more nocturnal leakage. However, there were no differences in the bowel function, continence score, and quality of life at 1 year. There were no differences in the anorectal manometry and endoanal ultrasound findings.
                Coloplasty pouches resulted in more anastomotic leaks and minimal differences in bowel function. At present, the J-pouch remains the benchmark for routine clinical practice, and due care (including defunctioning stoma) should be exercised in situations requiring CP. We carried out a prospective, randomized, controlled trial to clarify the effect of tonsillectomy on the clinical course of periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome.
                Twenty-six consecutive children (mean age 4.1 years) with at least 5 PFAPA attacks were recruited from 3 tertiary care pediatric hospitals during 1999-2003 and randomly allocated to tonsillectomy or follow-up alone. They were all followed up with symptom diaries for 12 months. Tonsillectomy was allowed after 6 months in the control group if the attacks recurred.
                Six months after randomization all 14 children in the tonsillectomy group and 6/12 children in the control group (50%) were free of symptoms (difference 50%, 95% confidence interval 23% to 75%, P < .001). Tonsillectomy was performed on 5/6 of the patients in the control group who still had symptoms after 6 months. The remaining unoperated child in the control group had recurrences of the fever episodes throughout the follow-up, but the symptoms became less severe, and the parents did not choose tonsillectomy.
                Tonsillectomy appeared to be effective for treating PFAPA syndrome. The fever episodes ceased without any intervention in half of the control subjects. We conclude that although the mechanisms behind this syndrome are unknown, tonsillectomy can be offered as an effective intervention for children with PFAPA. Functional results after rectal resection with straight coloanal anastomosis are poor. While most functional aspects are improved with coloanal J pouch anastomosis, it is still unclear whether this translates into better quality of life. The aim of this trial was to investigate health-related quality of life as a primary endpoint in patients undergoing sphincter-saving rectal resection.
                Sixty-four patients were randomized to either straight (n = 32) or coloanal J pouch (n = 32) anastomosis. Patients were studied before operation, at the time of stoma reversal and at 3-month intervals for 1 year thereafter. Quality of life was measured using two generic (Gastrointestinal Quality of Life Index and European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30) and one disease-specific (EORTC QLQ-CR38) instruments. Functional results using a standardized score as well as manometric variables were recorded.
                Thirty-nine patients (19 with a pouch and 20 with a straight anastomosis) completed the trial. There was a marked difference between the two groups with regard to quality of life profile. Patients with a pouch reconstruction had a significantly better quality of life, particularly in the early postoperative period.
                Patients undergoing low anterior rectal resection and coloanal J pouch reconstruction may expect not only better functional results but also an improved quality of life in the early months after surgery compared with patients who receive a straight coloanal anastomosis. Cases treated surgically using wide excision plus classic Limberg flap or wide excision plus asymmetric modified Limberg flap were compared with respect to complications and patient comfort in the postoperative period.
                In this prospective, randomized study, 68 of 70 patients were followed for a mean of 29.22 (range, 6-44) months after wide excision plus classic Limberg flap (Group 1, n=35) and after asymmetric modified Limberg flap closure (Group 2, n=33).
                There were significantly more macerations in Group 1 (P<0.001). All macerations were detected on the lower part of the incision left on the intergluteal sulcus, and infections occurred subsequent to maceration. The infection rate was statistically higher in Group 1 than in Group 2 (P=0.028). We noted that as a result of these complications, time to suture removal (P=0.001), discharge from hospital (P=0.001), and time off from work (P=0.001) were significantly longer for Group 1 than for Group 2. There were two recurrences in the inferior part of the suture line in Group 1 and none in Group 2, which showed no statistical difference (P=0.493).
                The deep intergluteal sulcus and midline gap were slightly flattened over the anococcygeal region. The vacuum effect was decreased, and there were less macerations and fewer infections. Time off from work and discharge time from hospital were shortened by eliminating the moisture effect and reducing complications by lateralizing the lower part of the suture line. As the few randomized controlled trials available in the literature comparing botulinum toxin (BT) injection with established endoscopic treatment of achalasia cardia, i.e. pneumatic dilatation, showed conflicting results, we conducted a prospective randomized trial. Seventeen consecutive patients with achalasia cardia diagnosed during a period between December 1997 and February 2000 were randomized into two treatment groups [pneumatic dilatation by Rigiflex dilator (n=10), BT injection by sclerotherapy needle into four quadrants of lower esophageal sphincter (LES) (n=7) 80 units in five cases, 60 units in two cases] after dysphagia grading, endoscopy, barium esophagogram, and manometry, all of which were repeated 1 week after treatment. Patients were followed up clinically for 35.2+/-14 weeks. Chi-squares, Wilcoxon rank-sum test, Kaplan-Meier method and log-rank tests were used for statistical analysis. After 1 week, 6/7 (86%) BT-treated vs. 8/10 (80%) dilatation-treated patients improved (P=NS). There was no difference in LES pressure and maximum esophageal diameter in the barium esophagogram in the two groups before therapy. Both therapies resulted in significant reduction in LES pressure. The cumulative dysphagia-free state using the Kaplan-Meier method decreased progressively in BT-treated compared with dilatation-treated patients (P=0.027). Two patients with tortuous megaesophagus, one of whom had failed dilatation complicated by perforation previously, improved after BT. One other patient in whom pneumatic dilatation had previously failed improved in a similar manner. BT is as good as pneumatic dilatation in achieving an initial improvement in dysphagia of achalasia cardia. It is also effective in patients with tortuous megaesophagus and previous failed pneumatic dilatation. However, dysphagia often recurs during 1-year follow up.
The trial provided some weak and unreliable evidence that there was no significant difference in the effectiveness of minimal incision palatopharyngoplasty versus the same procedure performed simultaneously with an individually tailored pharyngeal flap or sphincter pharyngoplasty for correcting velopharyngeal insufficiency associated with submucous cleft palate.
