Comparison of grip strength evolution after carpal tunnel release by three different techniques

Carpal tunnel syndrome (CTS)secondary to compression of the median nerve in the palm is the most frequent nerve entrapment of the upper extremity. Some forms are accessible to medical treatment,others need surgical treatment.The simple section of the transverse carpal ligament has been successfully used with predictable relief of distal paresthesia.However,diminished grip strength and/or palmar soreness are frequently an issue,resulting in a delayed return to work and recreational activities.The recent introduction of endoscopic release of CTS bolstered by commercial benefits has led us to set up a randomized prospective study to compare evolution of grip strength after three methods of carpal tunnel release (CTR)performed by the same surgeon: simple open section of the ligament, open section with ligament reconstruction,and endoscopic release (Agee procedure)

Locally Advanced Colorectal Cancer: True Peritoneal Tumor Penetration is Associated with Peritoneal Metastases

Findings show T4 colorectal cancer (CRC) to be a risk factor for the development of peritoneal metastases (PM). Heterogeneity regarding peritoneal involvement of T4 tumors might explain the wide range of reported PM incidences (8-50%). Hyperplastic and mesothelial inflammatory reactions complicate evaluation of the exact primary tumor involvement of the peritoneal layer. This retrospective cohort study aimed to assess the association between either inflammatory peritoneal reaction or peritoneal involvement of the primary tumor and the risk of PM. Since 2010, pathologists at UZ Leuven have systematically categorized peritoneal involvement in peritoneal reaction with tumor less than 1 mm from the peritoneal surface or true peritoneal penetration. All patients undergoing resection of CRC between January 2010 and July 2013 who fulfilled either of these pathologic criteria were included in this study. The study enrolled 159 CRC patients. Peritoneal reaction with tumor less than 1 mm from the peritoneal surface was present in 43 patients and true peritoneal penetration in 116 patients. Overall, 29 patients (18%) had synchronous PM, and 30 patients (23%) had metachronous PM. In the multivariable analysis, true peritoneal penetration, in contrast to peritoneal reaction with tumor less than 1 mm from the peritoneum, was associated with greater risk of PM (odds ratio [OR], 2.518; range, 1.038-6.111; p = 0.041) and lymph node involvement (N1: OR, 1.572; range, 0.651-3.797 vs N2: OR, 4.046; range, 1.549-10.569; p = 0.014). Histologically confirmed true peritoneal penetration by CRC, rather than inflammatory peritoneal reaction constitutes a high risk for PM. With evolving treatment strategies that aim to treat PM in an earlier phase, identification of high-risk patients becomes highly important clinicall

Risk Factors for Small Bowel Obstruction After Laparoscopic Ileal Pouch-Anal Anastomosis for Inflammatory Bowel Disease: A Multivariate Analysis in Four Expert Centres in Europe

BACKGROUND AND AIMS: Although laparoscopy is associated with a reduction in adhesions, no data are available about the risk factors for small bowel obstruction [SBO] after laparoscopic ileal pouch-anal anastomosis [IPAA]. Our aims here were to identify the risk factors for SBO after laparoscopic IPAA for inflammatory bowel disease [IBD]. METHODS: All consecutive patients undergoing laparoscopic IPAA for IBD in four European expert centres were included and divided into Groups A [SBO during follow-up] and B [no SBO]. RESULTS: From 2005 to 2015, SBO occurred in 41/521 patients [Group A; 8%]. Two-stage IPAA was more frequently complicated by SBO than 3- and modified 2-stage IPAA [12% vs 7% and 4%, p = 0.04]. After multivariate analysis, postoperative morbidity (odds ratio [OR] = 3, 95% confidence interval [CI] = 1.5-7, p = 0.002), stoma-related complications [OR = 3, 95% CI = 1-6, p = 0.03] and long-term incisional hernia [OR = 6, 95% CI = 2-18, p = 0.003] were predictive factors for SBO, while subtotal colectomy as first surgery was an independent protective factor [OR = 0.4, 95% CI = 0.2-0.8, p = 0.002]. In the subgroup of patients receiving restorative proctocolectomy as first operation, stoma-related or other surgical complications and long-term incisional hernia were predictive of SBO. In the patient subgroup of subtotal colectomy as first operation, postoperative morbidity and long-term incisional hernia were predictive of SBO, whereas ulcerative colitis and a laparoscopic approach during the second surgical stage were protective factors. CONCLUSIONS: We found that SBO occurred in less than 10% of patients after laparoscopic IPAA. The study also suggested that modified 2-stage IPAA could potentially be safer than procedures with temporary ileostomy [2- and 3-stage IPAA] in terms of SBO occurrence.status: publishe
