ABSTRACT
BACKGROUND: Surgical management of complete rectal prolapse is challenging. We present our results with the novel technique stapled transanal longitudinal posterior proctectomy (STALPP) in patients with complete rectal prolapse. METHODS: We performed a retrospective study in two hospitals from January 2005 to December 2012. Twenty-one patients with complete rectal prolapse were included. In all patients, STALPP was performed. The study variables were operative time, intraoperative bleeding, number of cartridges used, length of rectum prolapsed through the anus, length of rectal wall resected, length of hospital stay and preoperative and postoperative Wexner continence score and manometric measurement of anal canal resting tone and squeeze pressure. RESULTS: The median length of prolapsed tissue was 13 cm; the mean Wexner score in the preoperative and postoperative period was 15.95 and 4.95, respectively (p = 0.025). The mean resting tone improved from 23.3 to 32.85 mmHg postoperatively (p = 0.03), as did maximal squeeze pressure from 31 to 62.7 mmHg (p = 0.003). Median operative time was 65 min; median intraoperative bleeding was 12 ml; there was no postoperative bleeding, and no reinterventions were required. The median number of cartridges used was 4. The median length of resected wall in the right posterolateral sector was 8 and 6 cm in the left. The median length of hospital stay was 4 days, and the mean follow-up period was 2 years. No mortality was reported. CONCLUSIONS: Stapled transanal longitudinal posterior proctectomy is a safe and feasible surgical alternative for patients with complete rectal prolapse.

BACKGROUND: Peroral endoscopic myotomy has recently been developed and performed on patients with good results. AIMS: To evaluate the technical feasibility of peroral endoscopic full-thickness and partial thickness myotomy in a porcine model. MATERIAL AND METHODS: Eighteen criollo pigs were randomly assigned to 2 groups: group A (partial-thickness myotomy) and group B (full-thickness myotomy). The mucosal defect proximal to the myotomy site was left open. On the seventh postoperative day the pig was euthanized and follow-up surgical exploration was performed. The duration of each procedure, postoperative progression of the animal, complications, and anatomopathologic findings were registered. RESULTS: The procedure was viable in all the pigs. The mean surgery duration was 81±35.3min (group A 51.11±11.12, group B 111±22.61; P<.05). The main complication during myotomy was subcutaneous emphysema (16%). The histopathologic study of the group A surgical specimens reported complete circular myotomy in all cases, and complete circular and longitudinal myotomy was reported in 100% of the group B sample. CONCLUSIONS: The endoscopic myotomy technique is feasible. Endoscopic partial-thickness myotomy was associated with shorter surgery duration and better results during the intraoperative period and the 7-day follow-up.

A total of 11 prospective cases of endoscopic ultrasound (EUS)-guided cholangio-drainage (EUCD) in patients with end-stage biliopancreatic cancer and biliary tract obstruction are reported. Other available drainage methods (endoscopic retrograde cholangiopancreatography and/or percutaneous transhepatic biliary drainage) of the biliary tract were attempted without success prior to EUS. Technical and clinical success was achieved in 10/11 patients (91%) and in 9/10 patients (90%), respectively. Bilirubin decreased by more than 50% in 7/11 patients (64%). One patient had a complication that required re-intervention and another patient developed biloma. No mortality directly related to the procedure was documented. In conclusion, EUCD is a good alternative for patients with malignant obstruction of the biliary tract in whom other drainage methods have failed.

INTRODUCTION: Endoscopic retrograde cholangiopancreatography (ERCP) is the treatment of choice for symptomatic choledocholithiasis during pregnancy. In pregnant patients, aside from the risks inherent in the procedure and sedation, there is the added concern of the potentially damaging effects of ionizing radiation on the fetus. AIM: To describe the maternal and fetal results of ERCP performed to resolve symptomatic choledocholithiasis in pregnant patients. MATERIALS AND METHODS: A retrospective, descriptive, observational, and cross-sectional study was conducted. It included pregnant patients with choledocholithiasis that underwent ERCP within the time frame of June 2017 and June 2018. RESULTS: The study included 9 pregnant patients, with a mean gestational age of 24.1 weeks, that underwent ERCP. There were no maternal or fetal complications associated with sedation, mean fluoroscopy time was 26.7seconds, and one patient (11.1%) presented with mild post-ERCP pancreatitis that was resolved through medical management. Pregnancy progression was normal in 100% of the cases, resulting in the birth of neonates with a normal Apgar score, a mean weight of 3,120g, a mean length of 49.94cm, and a mean gestational age of 38.37 weeks. At follow-up at 6 months, the infants had a mean weight of 7.1kg and a mean length of 66.94cm. CONCLUSIONS: The results from our hospital center were similar to those described in the international literature, showing that ERCP in our medical environment is a feasible, safe, and efficacious method for both the mother and fetus. When performed by an experienced endoscopist, it should be considered the treatment of choice for choledocholithiasis in pregnant patients.
ABSTRACT
BACKGROUND: Dilatation of the intercellular spaces by electron microscopy has been considered as an early morphological marker of tissue injury in gastroesophageal reflux disease. The degree of dilatation in Barret's esophagus in currently unknown. OBJECTIVES: To determine the frequency of dilated intervellular spaces in Barrett's esophagus. MATERIAL AND METHODS: Cross-sectional and prospective analysis of consecutive patients with gastroesophageal reflux disease. We selected symptomatic patients > 18 years and both sexes. Patients with recent PPI use (< 14 days), H-2 antagonists, NSAID's or previous upper GI tract surgery were excluded. VARIABLES INCLUDED: Clinical-demographic data, Carlsson-Dent score, conventional endoscopy findings, pH-metry results (in non-erosive) and normal mucosal biopsies at 2 and 5 cm above the squamocolumnar junction. Dilation of intercellular spaces was measured by electron microscopy. STATISTICS: Chi square test with a significance level 0.05 was calculated. The following four groups were compared: a) non-erosive reflux disease (n = 14); b) erosive esophagitis (n = 5); c) Barrett's esophagus (n = 13); and d) healthy controls (n = 5). RESULTS: the dilation of intervellular spaces was increasingly greater form non-erosive revlux to Barrett's esophagus and higher in biopsies taken at 5 cm than at 2 cm of the squamous columnar junction (2.72 +/- 1.35 vs. 1.71 +/- 0.48 microg) (p = 0.001). There was no difference between biopsies at 2 and 5 cm in the order groups. CONCLUSION: dilation of intercellular spaces was greater in Barrett s esophagus than in the other groups and higher at 5 cm from the squamocolumnar junction.
