RESUMO
Diagnosis of intra-abdominal diseases in critically ill patients remains a clinical challenge. Physical examination is unreliable whereas exploratory laparotomy may aggravate patient's condition and delay further evaluation. Only a few studies have investigated the place of computed tomography (CT) on this hazardous situation. We aimed to evaluate the ability of CT to prevent unnecessary laparotomy during the management of critically ill patients. Charts of all consecutive patients who had undergone an emergency nontherapeutic laparotomy from 1996 to 2013 were retrospectively studied and patient's demographic, clinical characteristics, and surgical findings were collected. During this period 59 patients had an unnecessary laparotomy. Fifty-one patients had at least one preoperative imaging and 36 had a CT scan. CT scans were interpreted to be normal (n = 12), with minor anomalies (n = 10), or major anomalies (pneumoperitoneum, portal venous gas/pneumatosis intestinalis, thickened gallbladder wall, and small bowel obstruction signs). Surgical exploration was performed through laparotomy (n = 55) or laparoscopy. Overall mortality was 37% with a median survival after surgery of 7 days. In univariate analysis, hospitalization in ICU before surgical exploration was the only factor related to death. In our series CT scans, objectively interpreted, helped avoid unnecessary surgical exploration in 61% of our patients.

Stump appendicitis is an underestimated condition and a diagnostic trap that few surgeons think about when faced against localized pain in the lower-right abdomen. Misdiagnosis and therefore delay of the appropriate treatment results in increased morbidity. We report the case of a patient who presented a 7-day history of right iliac fossa abdominal pain. She had undergone open appendectomy in childhood. Stump appendicitis was not diagnosed immediately despite imaging (CT and MRI) and exploratory laparoscopy. In conclusion, surgeons and gastroenterologists need a heightened awareness of the possibility of stump appendicitis.

BACKGROUND: The aim of this study was to evaluate the effect of perioperative alfacalcidol on postoperative hypocalcemia after total thyroidectomy. METHODS: A total of 219 patients scheduled for total thyroidectomy were randomized into groups not receiving (group A) or receiving (group B) perioperative alfacalcidol. Postoperative hypocalcemia was compared between groups on postoperative day (POD) 1 and POD2. Patients with hypocalcemia (<2.00 mmol/L) received oral calcium supplementation. Calcium and vitamin D levels were measured at 5-week and 6-month follow-ups. RESULTS: The incidence of symptomatic hypocalcemia was significantly lower in group A (P = .02), whereas similarly low levels of calcemia were observed in both groups on POD1 (37% and 30%, respectively; P = not significant) and persisted on POD2 (14% and 6%, respectively; P = not significant). Patients with severe hypocalcemia (<1.90 mmol/L) showed faster recovery in group A compared with group B (6% vs 1%, P = .04). At 5 weeks, calcium and vitamin D levels were similar between the groups. Six months after surgery, 4% (group A) versus 0% (group B) of subjects exhibited permanent hypoparathyroidism (P = .04). CONCLUSIONS: Although the treatment did not correct vitamin D deficiency, perioperative alfacalcidol uptake resulted in decreased transient hypocalcemia and related symptoms in patients undergoing total thyroidectomy.

BACKGROUND: Primary hyperaldosteronism (PHA) is potentially curable by laparoscopic unilateral adrenalectomy (LUA). Pre-operative assessment rarely differentiates adrenal adenoma from hyperplasia. This study aimed to evaluate the results of LUA for PHA according to pathologic findings when an adrenal mass was identified unequivocally on a CT scan. METHODS: A retrospective analysis of LUA for PHA from July 1997 to May 2008 was performed. The minimal follow-up was 6 months. We considered hypertension to be cured in patients with normal blood pressure without antihypertensive medication (AM). Improvement was defined by a decrease of AM. RESULTS: Fifty-seven patients were included. Thirty-six patients (63%) had an adrenal adenoma and 21 (37%) a hyperplasia. The median follow-up was 6.4 years. Hypokalemia was cured in all patients, 33 patients (58%) were cured of their hypertension, and 23 (96% of the 24 noncured patients) were improved with a reduction of the number of AM. Predictive factors for a cure were: gender, age, BMI, duration of hypertension, number of pre-operative AMs, pre-operative arterial systolic blood pressure, creatinin and plasma renin activity. Postoperative predictive factors were pathology, size of the mass, and systolic and diastolic arterial pressures. In the multivariate analysis the only remaining factor was pathology. CONCLUSION: LUA for PHA cured all patients from their hypokalemia and cured or improved hypertension in 98%. Pre-operative diagnosis of adenoma or hyperplasia is not mandatory but it is important to warn patients that hypertension can persist after adrenalectomy, especially in case of adrenal hyperplasia, although this hypertension is easier to control.
