Abstract Background: The pear shape of an inflated balloon is thought to be a gold standard of a successful percutaneous balloon compression (PBC). However, neither how the balloon shape changes nor why it changes in that way (the anatomic basis) has not yet been fully described. Methods: Radiographs from over 150 percutaneous balloon compression (PBC) cases were thoroughly evaluated. We proposed a model of changing balloon shape in Meckel's cave (MC) and 70 cases were followed up over 2 years, in which therapeutic effect was measured.Results: We found that the balloon changed stereotypically in MC. The model that we proposed is consistent with the description of the structures of MC and its surroundings in the literature. The distinct pear (pear in MC) brought about a far better surgical result than other shapes (p < 0.01).Conclusion: Our study showed how and why the balloon shape changed during PBC surgery. The model provides favorable guidance for PBC surgery.

ABSTRACT Objective: to analyze the surgical treatment of patients with recurrent megaesophagus followed at the esophageal-stomach-duodenal outpatient clinic of the Hospital de Clínicas - UNICAMP. Methods: a retrospective study, from 2011 to 2017, with 26 patients with Chagas or idiopathic megaesophagus, surgically treated, and who recurred with dysphagia. Clinical, endoscopic and radiographic aspects were assessed and correlated with the performed surgical procedures. Results: 50% had dysphagia for liquids, 69% regurgitation, 65.3% heartburn, 69.2% weight loss and 69.2% had Chagas disease. In addition, 38.4% had megaesophagus stage 1 and 2 and 61.5% stage 3 and 4. Regarding the reoperations, 53% of them underwent Heller-Pinotti surgery by laparoscopy, Serra-Dória in 30.7% and esophageal mucosectomy in 7.9%. In 72% of the reoperations there were no postoperative complications, and 80% of the patients had a good outcome, with reduction or elimination of dysphagia. Among the reoperated patients undergoing the laparoscopic Heller-Pinotti technique, three reported little improvement of dysphagia in the postoperative period and among those who underwent Serra-Dória surgery, 100% had no dysphagia. It was observed that, when the time between the first procedure and the reoperation was longer, the better the surgical result was, with statistical significant decreased dysphagia (p=0.0013, p<0.05). Conclusions: there was a preference to perform laparoscopic re-miotomy and, as a second option, Serra-Dória surgery, for patients with recurrent megaesophagus. Esophagectomy or esophageal mucosectomy were reserved for more severe patients.

Background: The aim of this study is to determine the effectiveness of McIndoe Vaginoplasty in the creation of a neovagina for patients with vaginal agenesis.Methods: this is a retrospective study of 50 cases of vaginal agenesis, who underwent McIndoe Vaginoplasty over a period of 8 years (2004-2012) by using skin graft in 25 cases and amnion as graft in the remaining.Results: McIndoe Vaginoplasty was performed successfully in all 50 patients and post-surgical result was acceptable to the patient psychologically, sexually and aesthetically.Conclusions: McIndoe Vaginoplasty is a safe and effective procedure for providing a satisfactory and functional vagina in patients with MRKH syndrome.

Abstract BACKGROUND Postoperative three-dimensional digital subtraction angiography (3D-DSA) is the gold standard in evaluating intracranial aneurysm (IA) remnants after clipping. Should intraoperative 3D-DSA image quality be equally good as postoperative 3D-DSA, it could supplant the latter as standard of care for follow-up of clipped IA. OBJECTIVE To directly compare the quality of assessment of clipped IA by intraoperative and postoperative 3D-DSA. METHODS From a prospective cohort of 221 consecutive patients who underwent craniotomy for IA treatment in a hybrid operating room, we retrospectively studied 26 patients who had both intraoperative and postoperative 3D-DSA imaging of their clipped aneurysm. Comparison of intraoperative and postoperative 3D-DSA images (blinded for review) included parameters that affected image quality and differences between the 2 periods. RESULTS In the 26 patients with 32 clipped IAs, the mean interval was 11 ± 7 mo between intraoperative and postoperative imaging 3D-DSA examinations. Reconstruction with multiple clips was used in 14 (44%) cases. Of 15 remnants, 9 (60%) were small (&lt;2 mm). In comparing intraoperative and postoperative 3D-DSA, no discordance or discrepancy in assessment of the surgical result was noted for any clipped IA, and overall imaging quality was excellent for both modalities. Factors affecting minor differences in image quality were not identified. CONCLUSION Compared with postoperative 3D-DSA, intraoperative 3D-DSA images achieved equally high quality and effective, immediate interpretation of the surgical clipping result. With comparable imaging quality and no discordant findings, intraoperative 3D-DSA could replace postoperative 3D-DSA to become the standard of care in IA surgery.

Presurgical nasoalveolar molding (PNAM) is a key step in the early management of cleft babies. It involves making an impression of the alveolar segments and the lip elements, after which an appliance is fabricated and activated to achieve optimal alveolar and nasal positions for a superior surgical result. These appliances are fabricated and activated in babies as young as 10 days, and the molding is ideally carried on till the baby is ready for the primary lip repair. This article outlines in detail a digital method of fabricating the PNAM appliance using a combination of intraoral scans, computer-assisted digital software, and computer-assisted machining, facilitated by milling machines. This process obviates impression making and the subsequent laboratory procedures.
