Drugs used for sedation/analgesia during gastrointestinal (GI) endoscopy, including midazolam, fentanyl, and propofol, result in short-term, reversible decline in cognitive function. This prospective cohort trial aimed to identify the sedative/analgesic regimen associated with the least impairment of cognition at the time of discharge.

Precisely locating benign upper gastrointestinal tumors during laparoscopic-endoscopic surgery remains difficult and inaccurate. We describe reverse laser-supported diaphanoscopy (RLSD) for locating gastrointestinal tumors during laparoscopic surgery and present prospective evaluation results of the first cases.

Whether the reported theoretical benefits of single-port laparoscopic (SPL) approach can be converted to superior clinical outcomes is still unknown for ulcerative colitis (UC) patients undergoing second-stage proctectomy. This study aimed to compare the short-term postoperative and long-term pouch-related functional outcomes of SPL, multiport laparoscopic (MPL), and direct view (DV) completion proctectomy with ileal-pouch anal anastomosis (CP/IPAA).

Obesity is associated with nonalcoholic fatty liver disease which is one of the most common causes of chronic liver disease. FibroScan is a noninvasive tool for liver stiffness measurement and controlled attenuation parameter to evaluate liver steatosis and fibrosis. We aimed to demonstrate the effect of laparoscopic sleeve gastrectomy on liver steatosis and fibrosis. Of the 120 consecutive patients screened, 72 were enrolled in this study. FibroScan M probe and XL probe were used for the evaluation of liver steatosis and fibrosis. Fifty-two patients (72.2%) were female individuals and 20 (27.8%) were male individuals; the mean age was 37.9±10.4 years. Percentage of excess weight loss was significant at the third and sixth months: 57.2±18.3 (P<0.05) and 81.4±24.6 (P<0.05), respectively. Mean preoperative controlled attenuation parameter and liver stiffness measurement values were 309.2±68.7 dB/m and 7.5±5.0 kPa, respectively, and significantly declined to 217.4±56.4 dB/m and 5.6±2.5 kPa, respectively, at sixth postoperative month (P<0.001 and <0.01, respectively). These results suggest that laparoscopic sleeve gastrectomy is associated with significant improvement in liver steatosis and fibrosis. Bariatric surgery has a beneficial effect on nonalcoholic fatty liver disease in morbidly obese patients.

This study was designed to evaluate the impact of a standardized laparoscopic total mesorectal excision (TME) on the long-term oncologic outcome. Unselected consecutive patients with rectal cancer underwent a standardized laparoscopic TME with medial to lateral approach encompassing 9 sequential steps. From 2005 to June 2012, laparoscopic sphincter-preserving TME was attempted in 217 patients. Mean follow-up of all patients was a median of 91 months (range, 3 to 164 mo). The local recurrence rate was 6.5%, and the distant recurrence rate was 19.8%. The 10-year disease-free survival (DFS) rates were 76.4% and overall survival (OS) was 67.1%. In the converted group, DFS and OS were 50% and 46.7%, respectively. In the laparoscopic group, DFS and OS were 78.3% and 68.5%, respectively. A standardized laparoscopic sphincter-preserving TME resulted in a favorable long-term oncologic outcome in unselected patients with rectal cancer. Conversion to open surgery has impaired OS and DFS.

The endoscopic enteroenteral bypass could revolutionize the treatment of small bowel obstruction (SBO) in inoperable patients. We describe the technique of endoscopic delivery of a magnetic compression anastomosis device and the creation of an enteroenteral anastomosis in a patient with recurrent acute on chronic SBOs and prohibitively high operative risk. In this novel procedure, a magnetic compression anastomosis device is delivered on either side of the obstruction using a hybrid endoscopic/fluorographic technique, effectively bypassing the obstruction and relieving symptoms. The anastomosis was endoscopically evaluated at regular intervals postprocedure. By 7 days, healthy villi were visible through the mated magnetic rings. By 10 days, the anastomosis was widely patent. The rings passed through the ileostomy and were evacuated, and the patient’s symptoms completely resolved. The anastomosis remained widely patent at 1 year. In summary, this case demonstrates the benefit of magnetic compression anastomosis in a patient with SBO and high operative risk.

Recent evidence suggests routine colonoscopy after acute diverticulitis is not necessary but remains debatable. The aim of this study was to investigate the incidence of follow-up colonoscopic finding of adenoma, advanced neoplastic lesion, and adenocarcinoma after diverticulitis.

This study aimed to analyze the clinical safety and effectiveness of endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) in alleviating intractable abdominal pain caused by advanced pancreatic cancer. A total of 58 patients with inoperable pancreatic cancer who underwent EUS-CPN from May 2015 to December 2017 were enrolled. Pain levels before and after EUS-CPN were assessed and compared using the Visual Analogue Scale. The preoperative Visual Analogue Scale score was 8.2±2.3, which decreased significantly to 3.6±1.5 at 2 days after EUS-CPN and to 2.2±0.8 after 1 month. The response rate was 79.3%. No patient experienced serious complications; 14 patients experienced mild, transient side effects (self-limiting diarrhea, reflex hypotension, and worsening of abdominal pain) that resolved within 48 hours. For pancreatic cancer patients, EUS-CPN can effectively control pain with minimal adverse effects.

The combined resection of the vesical artery (VA) in laparoscopic lateral pelvic lymph node dissection (L-LPLD) was reported to facilitate the safe dissection of metastatic lymph nodes. However, whether or not the combined VA resection affects the urinary function remains controversial.
