Declining Rates of Surgery for Inflammatory Bowel Disease in the Era of Biologic Therapy.

BACKGROUND: Medical therapy for inflammatory bowel disease (IBD) has markedly advanced since the introduction of biologic therapeutics, although surgery remains an important therapeutic strategy for both Crohn's disease (CD) and ulcerative colitis (UC). This study evaluated how rates of bowel resection surgery and post-operative mortality for IBD have changed over the last decade in the era of biologic therapies. METHODS: The Nationwide Readmission Database (NRD) was queried for patients with IBD (based on ICD-9 and -10 diagnosis and procedure codes) who were hospitalized between 2010 and 2017. Longitudinal trends in bowel resection surgery, urgent surgery, and post-operative mortality were analyzed. RESULTS: During the 8-year period, a total of 1795,266 IBD-related hospitalizations (1,072,110 with CD and 723,156 with UC) were evaluated. There was an increase in the annual number of IBD patients hospitalized, but a statistically significant decrease in the proportion of IBD patients undergoing surgery, from 10 to 8.8% (p < 0.001) for CD and 7.7 to 7.5% (p < 0.001) for UC. From 2014 through 2017, the proportion of urgent surgeries remained stable around 25% (p = 0.16) for CD and decreased from 21 to 14% (p < 0.001) for UC. For CD, the rate of post-operative 30-day mortality varied between 1.2 and 1.6% and for UC decreased from 5.8 to 2.3% (p < 0.001). CONCLUSIONS: Analysis of a nationwide dataset from 2010 to 2017 determined that despite an increase in total admissions for IBD, a smaller proportion of hospitalized patients underwent surgery. A greater proportion of surgeries for UC were performed on an elective basis, and overall the rates of post-operative mortality for CD and UC decreased. The growth of biologic medical therapy during the study period highlights a probable contributing factor for the observed changes.

Transversus Abdominis Plane Block in Laparoscopic Colorectal Surgery: A Systematic Review.

BACKGROUND: Multimodal analgesia is important for postoperative recovery in laparoscopic colorectal surgery. Multiple randomized controlled trials have investigated the use of transversus abdominis plane local anesthetic infiltration as a method of decreasing postoperative pain and opioid consumption, with variable results. OBJECTIVE: This study aimed to examine the overall effect of transversus abdominis plane block in postoperative pain, opioid use, and speed of recovery in laparoscopic colorectal surgery. DATA SOURCES: A literature search was done with PubMed, EMBASE, Web of Knowledge, and Cochrane Library. Only randomized controlled trials were selected for review. INTERVENTIONS: Transversus abdominis plane local anesthetic infiltration versus no intervention, saline, or other techniques in laparoscopic colorectal surgeries was investigated. MAIN OUTCOME MEASURES: The primary outcome measured was postoperative pain on day 1, at rest or with activity. The secondary outcomes measured were postoperative pain beyond day 1, consumptions of opioid, and length of hospital stay. RESULTS: Eight clinical trials including 649 patients between 2013 and 2018 were included. Resting pain scores within 2 hours (standardized mean difference, -0.53; p = 0.01), 4 hours (standardized mean difference, -0.42; p = 0.004), and 6 hours (standardized mean difference, -0.47; p = 0.03) showed statistically significant reduction. Six studies including 413 patients demonstrated lower cumulative opioid consumption within 24 hours after surgery (standardized mean difference, -0.82; p = 0.01). Five studies including 357 patients did not show a significant difference in length of stay (standardized mean difference, -0.04; p = 0.82). LIMITATIONS: Local anesthetic used in block varied in type and quantity across different studies. There were heterogeneities in pain score measurements and opioid consumption. Patient populations may be different among studies. CONCLUSIONS: Transversus abdominis block can lead to a lower pain score at rest within the first 6 hours and reduce opioid consumption within the first 24 hours.

Colonic volvulus: presentation and management in metropolitan Minnesota, United States.

BACKGROUND: Management approaches for colonic volvulus are infrequently described in the literature in the United States, and many studies only report operative cases. OBJECTIVE: The aim of this study was to define the demographics, diagnostic and treatment approaches, and outcomes for patients with this disorder in the United States. DESIGN: This study is a retrospective review. SETTINGS: The study was conducted at a 7-hospital health system. PATIENTS: All patients diagnosed with colonic volvulus by International Classification of Diseases, Ninth Revision code were included. MAIN OUTCOME MEASURES: The primary outcomes measured were recurrence, complications, and mortality. RESULTS: One hundred three cases of volvulus (50 sigmoid, 53 cecal) were identified in 92 patients. Compared with cecal volvulus, sigmoid volvulus was more common in men, patients with neurologic diagnoses, and residents of skilled nursing home. Eighty-five percent of the cases presented were acutely obstructed. The diagnosis was established by abdominal x-ray (17%), contrast enema study (27%), CT scan (35%), or laparotomy (17%). Abdominal x-rays were insufficient for definitive diagnosis in 85% of cecal and 49% of sigmoid cases (p = 0.002). All patients with cecal volvulus were treated surgically. Seventy-nine percent of patients with sigmoid volvulus underwent successful nonoperative reduction, of whom 38% had subsequent surgery. Fifty-eight percent of patients with sigmoid volvulus were treated operatively. Resection with primary anastomosis was chosen in most cases (78%). Resection with end ostomy (10%), reduction and pexy (7%), and reduction alone (4%) were other approaches. The mortality rate was 5% (cecal 0%, sigmoid 10%; p = 0.012). There were no readmissions for recurrent cecal volvulus. Nonoperative treatment for sigmoid volvulus often failed (48%). Complication rates were higher in sigmoid volvulus cases (cecal 17%, sigmoid 34%; p = 0.047). LIMITATIONS: This study was limited by its retrospective, nonexperimental design. CONCLUSIONS: Although incidences of cecal and sigmoid volvulus are similar in the present series, sigmoid volvuli are more common in men, individuals with neurologic disease, and residents of nursing homes. Plain radiograph is insufficient to confirm cecal volvulus. The diagnosis is most often made with CT scans. The nonoperative management of sigmoid volvulus is associated with a high recurrence rate.
