Patients with Crohn's disease treated with anti-tumor necrosis factor alpha agents may have an increased risk of surgical complications. ⋯ In studies with a low risk of bias, anti-tumor necrosis factor alpha agents increased the risk of anastomotic complications. Inadequate bias control may lead to an underestimated risk of anastomotic complications.

Peritoneal carcinomatosis and liver metastases are common metastatic sites in patients who have colorectal cancer. Quite frequently, patients present with both synchronous liver and peritoneal metastases, which may result in a dilemma regarding the optimal treatment. ⋯ Both liver metastasis and peritoneal carcinomatosis were present in 8% of patients presenting with metastasized colorectal cancer. Population-based survival was only 5 months, with none of the patients undergoing treatment with curative intent. Median survival rates of up to 36 months after treatment with curative intent as published in the literature may be regarded as promising for selected patients.

Spin has been defined as "specific reporting that could distort the interpretation of results and mislead readers." ⋯ The distortion of nonsignificant results in laparoscopic trials was highly prevalent in this review. Readers of trials with nonsignificant results should be cautious of the authors' interpretations. Editors, reviewers, and publishers should ensure that author's conclusions correspond to the study's results and design.

Stress dose steroids are administered during the perioperative period to prevent complications of secondary hypoadrenalism, which can occur after long-term steroid treatment. Steroids also increase postoperative morbidity. Patients with ulcerative colitis often require steroid therapy before definitive surgery and often receive perioperative steroids in a variety of doses. ⋯ Although administration of stress dose steroids is not related to increased postoperative complications, the steroids do not appear to affect adrenal insufficiency outcomes. Patients who were treated with steroids for ulcerative colitis should be monitored carefully in the perioperative and early postoperative periods for signs of adrenal insufficiency, regardless of the steroid regimen used.

Surgical outcome results after repair for parastomal hernia are sparsely reported and based on small-scale studies. ⋯ In the present nationwide study, repair for a parastomal hernia was associated with high rates of morbidity, mortality, and repair for recurrence. Emergency repair was the only important risk factor to predict poor 30-day postoperative outcome.
