Prevalence of colorectal cancer and advanced adenoma in patients with acute diverticulitis: implications for follow-up colonoscopy.

BACKGROUND AND AIMS: Guidelines recommend colonoscopy after an episode of diverticulitis to exclude neoplasia but the effectiveness of testing is uncertain. Patients with complicated diverticulitis may be at higher risk for neoplasia, but most patients have uncomplicated disease. We examined the incidence of colorectal cancer (CRC) and advanced adenoma (AA) in patients with diverticulitis compared with patients undergoing screening colonoscopy. METHODS: CT scans from January 1, 2008, to May 1, 2013, at the University of Pittsburgh Medical Center (UPMC) were reviewed to identify those with confirmed acute diverticulitis. Subsequent surgical, colonoscopy, and pathology reports were abstracted to identify those with a diagnosis of AA and CRC. The incidence of neoplasia was compared with that reported for screening colonoscopy from a meta-analysis (n = 68,324), and from colonoscopy examinations at UPMC between 2013 and 2015 (n = 28,573). RESULTS: A total of 5167 abdominal/pelvic CT scan reports identified 978 patients with acute diverticulitis, among which 474 (48.5%) patients had undergone at least 1 colonoscopy or gastrointestinal surgery to April 2015. The CRC rate in patients with diverticulitis (13/474, 2.7%) was significantly higher (P < .0001) compared with both the meta-analysis (0.8%) and UPMC (0.3%). The AA rate (19/474, 4.0%) was similar to the rate in the meta-analysis (5.0%, P = .39) but significantly lower than at UPMC (7.7%, P = .003). The incidence of AA or CRC in complicated diverticulitis (10/141, 7.1%) did not differ significantly (P = .85) from the incidence of AA or CRC in uncomplicated diverticulitis (22/332, 6.6%). CONCLUSIONS: CRC after diverticulitis was significantly higher than that observed at screening colonoscopy and was not limited to complicated disease. Colonoscopy is advisable after the diagnosis of diverticulitis.

Idiopathic pneumatosis intestinalis secondary to lactulose use in patients with cirrhosis.

BACKGROUND AND AIM: Few case reports exist that link lactulose use with pneumatosis intestinalis in cirrhotics. This study investigates the relationship between lactulose use and idiopathic pneumatosis intestinalis in a cohort of cirrhotic patients. METHODS: This case series considers several notable cases of patients with idiopathic pneumatosis intestinalis and concurrent lactulose use. Idiopathic pneumatosis intestinalis was defined as pneumatosis intestinalis with no identifiable etiology. A cohort of 119 patients with cirrhosis and pneumatosis intestinalis were identified in a tertiary care setting, via chart review by a multidisciplinary team. Eleven of these patients were found to have idiopathic pneumatosis intestinalis. Nine of these patients were being treated with lactulose. RESULTS: Six out of 9 patients with idiopathic pneumatosis intestinalis that were being treated with lactulose saw resolution of pneumatosis intestinalis following discontinuation of treatment. CONCLUSIONS: The etiology of idiopathic pneumatosis intestinalis is likely multifactorial, but lactulose might play a preventable role in its formation.

Perioperative surgical care bundle reduces pancreaticoduodenectomy wound infections.

BACKGROUND: Pancreaticoduodenectomy (PD) is a complex surgical procedure with a historically high morbidity rate. The goal of this study was to determine if the implementation of a 12-measure perioperative surgical care bundle (SCB) was successful in reducing infectious and other complications in patients undergoing PD compared with a routine preoperative preparation group (RPP). METHODS: In this retrospective cohort study utilizing the HPB surgery database at the Thomas Jefferson University, we analyzed clinical data from 233 consecutive PDs from October 2005 to May 2008 on patients who underwent RPP, and compared them with 233 consecutive PDs from May 2008 to May 2010 following the implementation of the SCB. The SCB was the product of multidisciplinary discussion and extensive literature review. RESULTS: The RPP group and the SCB group had similar demographic characteristics. The overall rate of postoperative morbidity was similar between groups (42.1% versus 37.8%). However, wound infections were significantly lower in the SCB group (15.0% versus 7.7%, P = 0.01).The rates of other common complications, as well as postoperative hospital length of stay, readmissions, and 30-d postoperative mortality were similar between groups. CONCLUSIONS: The implementation of a SCB was followed by a significant decline in wound infection in patients undergoing PD.

Laparoscopic nephroureterectomy with a circumaortic left renal vein.

Renal vasculature anomalies can present technical challenges to laparoscopic urologic surgery. The use of preoperative imaging has made it possible to recognize and plan for such aberrant vascular anatomy. We describe a patient with a circumaortic left renal vein who underwent successful laparoscopic radical nephroureterectomy for the management of urothelial carcinoma of the renal pelvis.

Reoperative completion pancreatectomy for suspected malignant disease of the pancreas.

BACKGROUND: Completion pancreatectomy (CP) is a reoperative procedure to excise remnant pancreatic tissue after a prior pancreatic resection. In this study, we document our institution's experience with CP for recurrent malignant disease of the pancreas, describing indications for surgery, procedures performed, and patient outcomes. METHODS: We performed a retrospective review of 861 patients from the pancreatic surgery database in the Department of Surgery of Thomas Jefferson University from October 2005 to December 2010 to identify all cases of CP performed for suspected malignant disease. RESULTS: Eleven patients underwent reoperative CP at our institution from 2005 to 2010. The median time interval between the initial operation and CP was 32 mo. A combination of clinical symptoms, elevated tumor markers, and imaging studies were used for diagnosis of recurrent disease. Pancreatic ductal adenocarcinoma was the most common pathology, found in six patients. The postoperative complication rate was 18% and the median postoperative hospital length of stay was 6 d. There were no 30-d readmissions and no perioperative deaths. The 1-y survival rate following CP was 71% with an overall median survival of 17.5 mo. CONCLUSIONS: CP is a safe and effective option for a highly selected group of patients with suspected recurrent malignant disease of the remnant pancreas. Morbidity and mortality rates are within acceptable limits and similar to initial pancreatic resection. Eligibility depends heavily upon the absence of distant metastatic disease, technical factors for resection, and patient performance status.

One step endoscopic ultrasound guided management of pelvic abscesses: a case series.

BACKGROUND: Endoscopic management of pelvic abscesses not amenable to percutaneous drainage has been described. The technique employs endoscopic ultrasound (EUS)-guided placement of stents or drains, which may require multiple procedures, is cumbersome and uncomfortable for the patient. We describe the successful management of these abscesses in a single step involving EUS-guided lavage and instillation of antibiotics. METHODS: Six consecutive patients with seven symptomatic pelvic abscesses not amenable to percutaneous drainage were referred for EUS-guided drainage. The abscesses were aspirated with a 19-gauge needle under EUS guidance and serially lavaged with an equal aspirate to instillation volume of sterile saline until cleared of pus. The residual cavity was then instilled with gentamicin 40 mg/ml. Patients were followed clinically and radiographically with repeat computed tomography or magnetic resonance imaging. RESULTS: All patients had rapid resolution of symptoms. The abscesses disappeared completely in four patients. One patient with recurrent diverticulitis and abscess had marked decrease in abscess size and inflammation to permit planned sigmoid resection. One patient with Crohn's disease had clinical improvement and marked decrease in abscess size, permitting outpatient management of Crohn's disease. CONCLUSIONS: EUS-guided lavage and instillation of antibiotics is a simple, one-step approach in the management of pelvic abscesses and may obviate the need for prolonged drain management and repeat procedures in select cases.

The assessment and management of pain in cirrhosis.

PURPOSE OF REVIEW: The treatment of pain in patients with cirrhosis is complicated by unpredictable hepatic drug metabolism and a higher risk of adverse drug reactions. We aimed to conduct a scoping review regarding pain management in cirrhosis. RECENT FINDINGS: Despite the high prevalence of pain in patients with cirrhosis, there is little literature to guide the management of pain in this population. Complex pain syndromes and disease-specific pain etiologies exist are common in patients with cirrhosis. There are numerous contraindications and limitations when considering pharmacotherapy for analgesia in cirrhosis, specifically with non-steroidal anti-inflammatory drugs (NSAIDS) and opioid medications. Non-pharmacologic therapies for pain have not been specifically assessed in this population. SUMMARY: As with other populations, a multi-dimensional treatment approach to pain with a focus on physical, behavioral, procedural and pharmacologic treatment is recommended when caring for patients with cirrhosis and pain. However, more research is needed to evaluate opioid-sparing and non-pharmacologic analgesia in this population.
