RESUMEN
BACKGROUND Hepatic portal venous gas (HPVG) is a rare radiologic finding mostly associated with life-threatening diseases like bowel necrosis, but can also be benign; its overall mortality rate is 39-75%. In rare cases HPVG is associated with endoscopic procedures such as percutaneous endoscopic gastrostomy (PEG) placement. However, due to the rarity of this condition, there is no recommendation about its management. The aim of this case report was to describe a successful conservative management of HPVG without antibiotic administration based on the clinical presentation. CASE REPORT A 78-year-old male patient known for a history of esophageal cancer treated with radio- and chemotherapy, complicated by a post-radiation esophageal stenosis requiring a PEG tube placement 1 month prior was admitted to our Emergency Department for vomiting and abdominal pain. A contrast-enhanced abdominal CT scan showed small-bowel dilatation without obstruction, as well as gastric wall pneumatosis and HPVG. We opted for a conservative approach. The PEG was put to suction for 2 days. The clinical evolution was favorable, with resolution of abdominal pain and a restored transit on day 2. A follow-up CT scan at day 5 showed resolution of HPVG. Nutrition through the PEG was restored at day 6 without complication. CONCLUSIONS HPVG can be a benign finding after a PEG tube placement. Conservative management without antibiotics can be used in oligosymptomatic and hemodynamically stable patients after life-threatening associated diseases like bowel necrosis have been ruled out.

PURPOSE: It is currently unknown whether NASH (nonalcoholic steatohepatitis), as compared to simple steatosis, is associated with impaired postoperative weight loss and metabolic outcomes after RYGB surgery. To compare the effectiveness of Roux-en-Y gastric bypass (RYGB) on patients with NASH versus those with simple nonalcoholic fatty liver (NAFL). MATERIALS AND METHODS: We retrospectively retrieved data from 515 patients undergoing RYGB surgery with concomitant liver biopsy. Clinical follow-up and metabolic assessment were performed prior to surgery and 12 months after surgery. We used multivariate analysis of variance (MANOVA) and propensity score matching and we assessed for changes in markers of hepatocellular injury and metabolic outcomes. RESULTS: There were 421 patients with simple NAFL, and 94 with NASH. Baseline alanine and aspartate aminotransferases were significantly higher in patients with NASH (p < 0.01). Twelve months after the RYGB surgery, as determined by both MANOVA and propensity score matching, patients with NASH exhibited a significantly greater reduction in alanine aminotransferase (ß-coefficient - 12 iU/l [- 22 to - 1.83], 95% CI, adjusted p = 0.021) compared to their NAFL counterparts (31 matched patients in each group with no loss to follow-up at 12 months). Excess weight loss was similar in both groups (ß-coefficient 4.54% [- 3.12 to 12.21], 95% CI, adjusted p = 0.244). Change in BMI was comparable in both groups (- 14 (- 16.6 to - 12.5) versus - 14.3 (- 17.3 to - 11.9), p = 0.784). CONCLUSION: After RYGB surgery, patients with NASH experience a greater reduction in markers for hepatocellular injury and similar weight loss compared to patients with simple steatosis.

BACKGROUND The incidence of neuroendocrine tumors (NETs) has increased in recent years. They can affect every area of the human body that presents cells with a secretory function. In this report, we focus on gastrointestinal NETs. The small bowel (SI) is the most affected area and SI-NETs have recently become more common than adenocarcinomas. Inside the small intestine, the appendix suffers from this pathology more than other organs. CASE REPORT Our case report deals with a 70 years-old man with extensive abdominal pain due to ingestion of an apricot kernel. A CT abdominal scan showed, around the kernel, a mechanical ileus with inflammation of the distal ileum and thickening of the intestinal wall. During the operation, we replaced laparoscopy with mini-laparotomy, performing an ileocecectomy due to suspicion of a tumor lesion. The histopathological exam revealed a well-differentiated neuroendocrine tumor (NET G1) of the distal ileum. CONCLUSIONS This case report shows that SI-NETs can be found in cases of small bowel occlusion. Depending on the size and distinction, such patients can have good survival rates.
