Utilizing functional lumen imaging probe in directing treatment for post-fundoplication dysphagia.

BACKGROUND: Esophagogastric junction obstruction (EGJO) post-fundoplication (PF) is difficult to identify with currently available tests. We aimed to assess the diagnostic accuracy of EGJ opening on functional lumen imaging probe (FLIP) and dilation outcome in FLIP-detected EGJO in PF dysphagia. METHODS: We prospectively collected data on PF patients referred to Esophageal Clinic over 18 months. EGJO diagnosis was made by (a) endoscopist's description of a narrow EGJ/wrap area, (b) appearance of wrap obstruction or contrast/tablet retention on esophagram, or (c) EGJ-distensibility index (DI) < 2.8 mm2/mmHg on real-time FLIP. In patients with EGJO and dysphagia, EGJ dilation was performed to 20 mm, 30 mm, or 35 mm in a stepwise fashion. Outcome was assessed as % dysphagia improvement during phone call or on brief esophageal dysphagia questionnaire (BEDQ) score. RESULTS: Twenty-six patients were included, of whom 17 (65%) had a low EGJ-DI. No patients had a hiatal hernia greater than 3 cm. Dysphagia was the primary symptom in 17/26 (65%). In 85% (κ = 0.677) of cases, EGJ assessment (tight vs. open) was congruent between the combination of endoscopy (n = 26) and esophagram (n = 21) vs. EGJ-DI (n = 26) on FLIP. Follow-up data were available in 11 patients who had dilation based on a low EGJ-DI (4 with 20 mm balloon and 7 with ≥ 30 mm balloon). Overall, the mean % improvement in dysphagia was 60% (95% CI 37.7-82.3%, p = 0.0001). Nine out of 11 patients, including 6 out of 7 undergoing pneumatic dilation, had improvement ≥ 50% in dysphagia (mean % improvement 72.2%; 95% CI 56.1-88.4%, p = 0.0001). CONCLUSIONS AND INFERENCES: Functional lumen imaging probe is an accurate modality for evaluating for EGJ obstruction PF. FLIP may be used to select patients who may benefit from larger diameter dilation.

Effect of comorbid conditions on adherence to colorectal cancer screening.

Potential barriers to colorectal cancer (CRC) screening include preexisting medical conditions (comorbidities), physician recommendation, psychosocial factors, and screening preparedness. This study's purpose was to investigate the impact of comorbid conditions on CRC screening among African Americans. A stage-matched randomized clinical trial was performed. Asymptomatic African Americans over age 50, with a primary care physician, and eligible for CRC screening were recruited at The Mount Sinai Hospital from 2005 to 2008. One hundred sixty-one patients were assessed for referral for, and completion of, CRC screening, comorbid conditions, "readiness to change," and number of physician visits within the observation period. Data was compared to a pretrial index to predict the likely effect of comorbid conditions on CRC screening. One hundred fifty-nine patients completed the study; 108 (68.9%) were referred for and 34 (21.2%) completed CRC screening. No demographic characteristics were associated with CRC screening completion. CRC screening referrals were similar for all patients, regardless of comorbidities or clinical visits. Comorbidities rated as having extreme influence on CRC screening showed a trend toward lower screening rates. There was a significant increase in screening rates among participants in advanced stages of readiness at enrollment. These data suggest that while comorbidities did not predict colonoscopy completion, they may play a role in concert with other factors. This is the only study to assess the effect of screening colonoscopy in an African American primary care setting. We must continue to explore interventions to narrow the disparate gap in screening and mortality rates.

Gastrointestinal Diseases in Pregnancy: Nausea, Vomiting, Hyperemesis Gravidarum, Gastroesophageal Reflux Disease, Constipation, and Diarrhea.

Many disorders of the gastrointestinal tract are common in pregnancy. Elevated levels of progesterone may lead to alterations in gastrointestinal motility which could contribute to nausea, vomiting, and/or GERD. Pregnancy-induced diarrhea may be due to elevated levels prostaglandins. This article reviews the normal physiologic and structural changes associated with pregnancy that could contribute to many of the common gastrointestinal complaints in pregnant patients. Additionally, the appropriate clinical and laboratory evaluations, other pathologic conditions that should be included in the differential, as well as the nonpharmacologic and pharmacologic therapies for each of these conditions is discussed.

Efficacy of laparoscopic pyloroplasty for the treatment of gastroparesis.

BACKGROUND: The modest results of nonoperative modalities for the treatment of gastroparesis necessitate greater consideration of surgical therapies. However, the role of surgery is not well defined. The aim of this study is to present our experience with laparoscopic pyloroplasty as early treatment for gastroparesis. STUDY DESIGN: Fifty patients with refractory gastroparesis underwent laparoscopic pyloroplasty (hand-sewn Heineke-Mikulicz configuration) from 2006 to 2013 at our institution. Preoperative and postoperative symptom data, gastric emptying scintigraphy, and technical outcomes of the procedure were reviewed. A single-factor ANOVA was performed for the comparison of continuous variables. Results are reported as mean ± SD or median absolute deviation. RESULTS: Thirty-four of 50 (68%) patients had previous foregut procedures and/or cholecystectomy. Thirty-two of 50 (64%) patients underwent concomitant procedures (ie, paraesophageal hernia repair and gastrostomy takedown) along with the pyloroplasty. Operative time, including combined procedures, blood loss, and length of stay were 175 ± 56 minutes, 64 ± 50 mL, 2.5 ± 2.7 days, respectively. There were no conversions to open technique or intraoperative complications. There were no suture-line leaks. The readmission rate was 14%. All patients had symptom follow-up and 33 (66%) had postoperative gastric emptying scintigraphy. Postoperative symptom improvement was reported by 82% of the patients (p < 0.001). Median preoperative T1/2 was 180 ± 73 minutes and postoperative T1/2 was 60 ± 23 minutes (p < 0.001). Five patients (10%), who had normalized postoperative T1/2 times, required other gastric emptying procedures; distal gastrectomy (n = 2), duodenojejunostomy (n = 2), and gastric stimulator placement (n = 1). CONCLUSIONS: Laparoscopic pyloroplasty is an effective early-treatment modality for selected cases of gastroparesis, with substantial improvement in objective gastric emptying times and low morbidity. The laparoscopic approach does not preclude subsequent procedures when necessary.

Fecal incontinence in the elderly.

Fecal incontinence (FI), the involuntary loss of formed stool, can a social and as well as hygiene problem and is often devastating for patients and their caretakers. Current data, which are probably underestimated, indicate that the occurrence is remarkably high. The etiology of FI is multifactorial; risk factors including advancing age, previous obstetric trauma, diabetes, fecal impaction, stroke, and dementia. The management of FI in the elderly depends on etiologic factors. However, there are many treatment options for sufferers of FI including bulking agents, antidiarrheals, anticholinergics, biofeedback, surgery for sphincter defects, and sphincter bulking devices. The appropriate treatment can be guided by a thorough workup of these patients and result in a significant improvement in quality of life.
