Nonalcoholic fatty liver disease (NAFLD) is prevalent in obese patients. We sought to determine the effects of bariatric surgery on the histological features of NAFLD. Two blinded pathologists graded liver biopsies done during bariatric procedures and subsequent operations in 160 patients using the Brunt classification. Data are mean ± SD. Interval between biopsies was 31 ± 26 months. Initial biopsies demonstrated steatosis 77 %, lobular inflammation 39 %, and chronic portal inflammation 56 %. Steatohepatitis was present in 27 %. Grade 2-3 fibrosis was present in 27 %, and cirrhosis was present in one patient. On post-bariatric biopsy, steatosis resolved in 75 %, lobular inflammation resolved in 75 %, chronic portal inflammation resolved in 49 %, and steatohepatitis resolved in 90 %. Fibrosis of any grade resolved in 53 % and improved in another 3 % of patients. Grade 2 fibrosis resolved in 58 %, improved in 3 %, and did not worsen in 11 %. Bridging fibrosis resolved in 29 %, improved in 29 %, and did not worsen in 29 %. Bariatric surgery is associated with resolution of steatosis or steatohepatitis in the majority of patients. More importantly, grade 2 or 3 (bridging) fibrosis is resolved or improved in 60 % of patients. Bariatric surgery should be considered as a treatment of NAFLD in severely obese patients.

Nasogastric tube (NGT) insertion is a routine procedure in the management of surgical patients. We report the second case of internal jugular vein perforation during NGT insertion. A 79-year-old man presented with diffuse abdominal pain secondary to a perforated viscus. Abdominal CT revealed pneumoperitoneum, necessitating emergent exploratory laparotomy. On post-operative Day 7, the patient developed mild abdominal distension and subjective nausea for which NGT placement was ordered for decompression. Tube placement was confirmed by insufflation of air without aspiration of gastric contents. Output from the NGT upon placement revealed frank blood. The patient then developed respiratory distress requiring intubation, followed by a fatal arrhythmia. Post-mortem exam revealed the trajectory of the NGT through the pharyngeal wall into the right internal jugular vein. This case illustrates the importance of systematic evaluation of all procedures, as the outcome resulted from failure to recognize the initial error in tube placement.
