Porto-mesenteric venous gas as a sign of gastric mucosal damage remitted after surgery: a case report.

Porto-mesenteric venous gas (PMVG) is a severe sign of abdominal organs damage. Imaging diagnostic criteria allow the detection of PMVG and should be applied in the presence of severe symptoms and signs of abdominal organs damage. Our case had clinical signs of epigastric pain and abdominal tenderness and ultrasonography and computed tomography evidence of PMVG and gastric cancer. The subsequent surgery, without complications, induced PMVG to disappear and the patient to be dismissed from hospital.

A network analysis of psychological, personality and eating characteristics of people seeking bariatric surgery: Identification of key variables and their prognostic value.

OBJECTIVE: The interplay among personality traits, anxiety and eating symptoms in candidates for bariatric surgery has never been investigated through the network analysis approach. Thus, we aimed to use this method to identify the key psychological traits that characterize these individuals and to assess their role as predictors of surgical outcomes. METHODS: One-hundred-eighty-five candidates for bariatric surgery filled in the State Trait Anxiety Inventory (STAI), the Revised Restraint Scale, the Power of Food Scale and the Temperament and Character Inventory-Revised (TCI-R) questionnaires. All these variables were included in a network analysis. Then, the most central network nodes were entered as independent variables in a regression model that included 9-month follow-up weight outcomes as the dependent variable. RESULTS: The network has showed a good stability. TCI-self directedness and harm avoidance scores and STAI state and trait anxiety scores were the nodes with the highest centrality in the network. Weight outcomes were assessed in 64 patients at follow-up. Among central nodes, low TCI-self directedness was found to be the only significant independent predictor of worse weight outcome. CONCLUSIONS: Our findings show for the first time the interplay between personality traits and symptoms in candidates for bariatric surgery combining the network approach with a follow-up evaluation. Low self-directedness has been proved to be the node with highest centrality and the only predictor of short-term weight outcome. These data suggest the importance to take into consideration personality and psychological variables either in the pre-surgery assessment or as possible targets for pre or post-surgery psychotherapeutic interventions.

Outcomes of sutureless total thyroidectomy in elderly.

INTRODUCTION: Thyroid disease is common in elderly population. The incidence of hypothyroidism and multinodular goiter increases with age. Surgery in elderly patients has been considered to be more hazardous than in a youthful population. Besides the traditional surgical hemostatic techniques, different hemostatic approaches, which further minimize the risk of bleeding and complications during thyroidectomy, have become available. Aim of this study was to review and compare the outcomes of total thyroidectomy (TT) in elderly performed with different energy system. METHODS: A total of 255 patients were eligible for the study and enrolled. One hundred and five patients with age >70 years (median age 76, range 70-90) constituted the elderly group (EG), whereas the young group (YG) was composed by 150 patients (median age 36, range 18-69). Each group was further divided into three subgroups, on the basis of the device used (none, Ligasure Precise/Small Jaw or Harmonic Focus) for performing TT as follows: conventional thyroidectomy in EG (CTE) and YG (CTY), Ligasure thyroidectomy (LTE and LTY) and Harmonic thyroidectomy (THE and HTY). Intra-operative and post-operative data, as well as complications rate, were collected. RESULTS: There was no significant difference between the elderly and the young patients treated with total thyroidectomy. Using of Harmonic Focus or Ligasure Precise/Small Jaw allowed a reduction of the duration of surgery (p < 0.05) than conventional approach; complication rate for hemorrhage, hypocalcemia and vocal cord paralysis was similar in all sub-groups. CONCLUSIONS: Total thyroidectomy in elderly patients is as safe as in the younger population. Moreover, using the Harmonic Focus and the Ligasure Precise/Small Jaw is a safe, effective, and time-saving alternative to the traditional suture ligation technique for thyroid surgery.

Worldwide burden of colorectal cancer: a review.

Colorectal cancer is a major public health problem, being the third most commonly diagnosed cancer and the fourth cause of cancer death worldwide. There is wide variation over time among the different geographic areas due to variable exposure to risk factors, introduction and uptake of screening as well as access to appropriate treatment services. Indeed, a large proportion of the disparities may be attributed to socioeconomic status. Although colorectal cancer continues to be a disease of the developed world, incidence rates have been rising in developing countries. Moreover, the global burden is expected to further increase due to the growth and aging of the population and because of the adoption of westernized behaviors and lifestyle. Colorectal cancer screening has been proven to greatly reduce mortality rates that have declined in many longstanding as well as newly economically developed countries. Statistics on colorectal cancer occurrence are essential to develop targeted strategies that could alleviate the burden of the disease. The aim of this paper is to provide a review of incidence, mortality and survival rates for colorectal cancer as well as their geographic variations and temporal trends.

Esophagogastric junction morphology assessment by high resolution manometry in obese patients candidate to bariatric surgery.

INTRODUCTION: Obesity is a strong independent risk factor of gastroesophageal reflux disease (GERD) symptoms and hiatal hernia development. Pure restrictive bariatric surgery should not be indicated in case of hiatal hernia and GERD. However it is unclear what is the real incidence of disruption of esophagogastric junction (EGJ) in patients candidate to bariatric surgery. Actually, high resolution manometry (HRM) can provide accurate information about EGJ morphology. Aim of this study was to describe the EGJ morphology determined by HRM in obese patients candidate to bariatric surgery and to verify if different EGJ morphologies are associated to GERD-related symptoms presence. METHODS: All patients underwent a standardized questionnaire for symptom presence and severity, upper endoscopy, high resolution manometry (HRM). EGJ was classified as: Type I, no separation between the lower esophageal sphincter (LES) and crural diaphragm (CD); Type II, minimal separation (>1 and < 2 cm); Type III, >2 cm separation. RESULTS: One hundred thirty-eight obese (BMI>35) subjects were studied. Ninety-eight obese patients referred at least one GERD-related symptom, whereas 40 subjects were symptom-free. According to HRM features, EGJ Type I morphology was documented in 51 (36.9%) patients, Type II in 48 (34.8%) and Type III in 39 (28.3%). EGJ Type III subjects were more frequently associated to Symptoms than EGJ Type I (38/39, 97.4%, vs. 21/59, 41.1% p < 0.001). CONCLUSIONS: Obese subjects candidate to bariatric surgery have a high risk of disruption of EGJ morphology. In particular, obese patients with hiatal hernia often refer pre-operative presence of GERD symptoms. Testing obese patients with HRM before undergoing bariatric surgery, especially for restrictive procedures, can be useful for assessing presence of hiatal hernia.

Effectiveness of an advanced hemostatic pad combined with harmonic scalpel in thyroid surgery. A prospective study.

INTRODUCTION: Hemostasis during thyroidectomy is essential; however the most efficient and cost-effective way to achieve this is unclear. The aim of this study was to evaluate the outcome of total thyroidectomy (TT) performed with the combination of harmonic scalpel (HS) and an advanced hemostatic pad (Hemopatch). METHODS: Patient undergone TT were divided into two groups: HS + hemopatch and HS + traditional hemostasis groups. The primary endpoint was 24-h drain output and blood-loss requiring reintervention. Secondary endpoints included surgery duration, postsurgical complications and hypocalcemia rates. RESULTS: Between September 2014 and March 2015, 60 patients were enrolled (30 to Hs + Hemopatch, 30 to Hs and standard hemostasis); 71.4% female; mean age 48.5 years. The 24-h drain output was lower in the HS + hemopatch group compared with standard TT. HS and hemopatch also had a shorter mean surgery time (p < 0.0001) vs standard TT. CONCLUSION: combination of hemopatch plus HS is effective and safe for TT with a complementary hemostatic approach.

Sutureless thyroidectomy.

OBJECTIVE: The ultrasonic scalpel is a surgical shear that uses high-frequency mechanical energy to enable simultaneous vessel sealing and tissue coagulation at the same time. We conducted a prospective study to compare the outcome of total thyroidectomy using the ultrasonic scalpel versus the device Ligasure in terms of safety, operative time, overall drainage volume, complications, hospital stay. METHODS: Between January 2008 and December 2013,400 patients (260 women, 140 men; mean age 46 years) undergoing thyroidectomy were randomized into two groups: group A, where Ultracision were used, and group B, where the Ligasure device was used. RESULTS: There was no significant differences between the two groups in terms of age, gender, indication for thyroidectomy, thyroid gland weight and diameter, histopathologic diagnosis, preoperative and postoperative serum calcium levels, postoperative complications and reoperative thyroid surgery, time of operation and amount of drainage. CONCLUSIONS: The ultrasonic scalpel and the Ligasure ares safe, effective, useful, and time-saving alternative to the traditional suture ligation technique for thyroid surgery. They simplified total thyroidectomy, eliminating the need for clamp-and-tie maneuvers while achieving efficient hemostasis.

Long term quality of life after laparoscopic antireflux surgery for the elderly.

BACKGROUND: Studies have previously shown laparoscopic antireflux surgery is a safe and effective treatment for GERD even in elderly patients. The aim of the current study was to evaluate patients receiving laparoscopic antireflux surgery before and after 65 years of age and to assess their surgical outcomes and improvements in long term quality of life. METHODS: Patients were given a standardized symptoms questionnaire and the Short-Form 36 Health Survey for quality-of-life evaluation before and after laparoscopic total fundoplication. RESULTS: Forty-nine patients older than 65 years of age were defined as the elderly group (EG) whereas the remaining 262 younger than 65 years of age were defined as the young group (YG). CONCLUSIONS: In conclusion, laparoscopic total fundoplication is a safe and effective surgical treatment for gastroesophageal reflux disease generally warranting low morbidity and mortality rates and a significant improvement of symptoms comparable. An improved long-term quality of life is warranted even in the elderly.

The impact of age and oral calcium and vitamin D supplements on postoperative hypocalcemia after total thyroidectomy. A prospective study.

BACKGROUND: Hypocalcemia caused by transient or definitive hypoparathyroidism is the most frequent complication after total thyroidectomy (TT). We aimed to compare the impact of age and the clinical usefulness of oral calcium and vitamin D supplements on postoperative hypocalcemia after TT, and to determine which risk factors are important for hypocalcemia incidence. METHODS: Two hundred consecutive patients treated by TT were included prospectively in the present study. All patients supplemented oral calcium and vitamin D in the post-operative time. The data concerning symptomatic and laboratoristichypocalcemia were collected. RESULTS: Symptomatic hypocalcemia developed only in 19 patients (9.5%), whereas laboratory hypocalcemia developed in 36 patients (18%). The risk for postoperative hypocalcemia was increate 20-fold for patients older than 50 years. CONCLUSIONS: Age is significantly associated with postoperative hypocalcemia. Implementing oral calcium and vitamin D after total thyroidectomy can reduce the incidence of hypocalcemia related to surgery.

Phenomenology and prognostic significance of delusions in major depressive disorder: a 10-year prospective follow-up study.

OBJECTIVE: The study explored the phenomenology and prognostic significance of delusions in major depressive disorder. METHOD: From 452 patients with DSM-III major depression, we selected those with at least one belief fulfilling both DSM-III prerequisites for a delusion (i.e., being of "delusional proportions" and being maintained with "delusional intensity"). These patients were compared to the others with respect to demographic, historical, and index episode features; time spent in a depressive episode during a prospective observation period; and 10-year outcome. The same comparisons were made between patients with mood-incongruent delusions and those with mood-congruent delusions only. The study covered the period between January 1, 1978, and December 31, 2005. RESULTS: About 20% of patients had at least one delusion in their index episode. An additional 5.3% had a belief fulfilling only one of the DSM-III prerequisites for a delusion. In about one quarter of delusional patients, the index episode was not "severe." Almost 10% of delusional patients had both mood-congruent and mood-incongruent delusions. In patients with delusions, time to syndromal recovery from index episode was longer and antipsychotic medication was more frequently used (both p < .0001). The presence of delusions predicted a higher depressive morbidity during the prospective observation period (p < .05), but not a poorer 10-year outcome. No variable discriminated patients with mood-incongruent delusions from those with mood-congruent delusions only. CONCLUSION: The presence of delusions in a major depressive episode has significant therapeutic and short-term prognostic implications. However, the boundary between delusions and nondelusional sustained preoccupations is somewhat fuzzy, and some DSM-IV assumptions concerning psychotic depression (i.e., that this depression is always "severe"; that in an individual patient, delusions will be either all congruent or all incongruent with depressed mood; and that mood-incongruent delusions are associated with a poorer prognosis) may be unwarranted.

Agitated "unipolar" major depression: prevalence, phenomenology, and outcome.

OBJECTIVE: This study aimed to explore how prevalent agitated "unipolar" major depression is, whether it belongs to the bipolar spectrum, and whether it differs from nonagitated "unipolar" major depression with respect to course and outcome. METHOD: The study was conducted from January 1, 1978, to December 31, 1996. From 361 patients with major depressive disorder, the authors selected those fulfilling Research Diagnostic Criteria for agitated depression. These 94 patients were compared to 94 randomly recruited patients with nonagitated major depressive disorder regarding demographic and historical features, the clinical characteristics of the index episode, the percentage of time spent in an affective episode during a prospective observation period, and the 5-year outcome. Patients with agitated major depressive disorder who had at least 2 manic/hypomanic symptoms in their index episode were compared to the other patients with agitated major depressive disorder with respect to the same variables. RESULTS: Patients with agitated major depressive disorder were more likely to receive antipsychotics during their index episode and spent a higher proportion of time in an affective episode during the observation period compared with patients with nonagitated major depressive disorder. The presence of at least 2 manic/hypomanic symptoms in the index episode was associated with a higher rate of family history of bipolar I disorder, a higher score for suicidal thoughts during the episode, a longer duration of the episode, and a higher affective morbidity during the observation period. CONCLUSION: The diagnosis of agitated major depressive disorder is not uncommon and has significant therapeutic and prognostic implications. The subgroup of patients with at least 2 manic/hypomanic symptoms may suffer from a mixed state and/or belong to the bipolar spectrum.

Agitated depression in bipolar I disorder: prevalence, phenomenology, and outcome.

OBJECTIVE: The study aimed to explore how prevalent agitated depression is in bipolar I disorder, whether it represents a mixed state, and whether it differs from nonagitated depression with respect to course and outcome. METHOD: From 313 bipolar I patients with an index episode of major depression, the authors selected those fulfilling Research Diagnostic Criteria for agitated depression. These 61 patients were compared to 61 randomly recruited bipolar I patients with an index episode of nonagitated depression and 61 randomly recruited bipolar I patients with an index episode of mania regarding demographic, historical, and clinical features. The two depressive groups were also compared regarding time to recovery from the index episode, treatment received for that episode, percentage of time spent in an affective episode during a prospective observation period, and 5-year outcome. RESULTS: Patients with agitated depression were consistently not elated or grandiose, but one-fourth had the cluster of symptoms with racing thoughts, pressured speech, and increased motor activity, and one-fourth had the paranoia-aggression-irritability cluster. Compared to patients with nonagitated depression, they had a longer time to 50% probability of recovery from the index episode, were more likely to receive standard antipsychotic drugs during that episode, and spent more time in an affective episode during the observation period. CONCLUSIONS: The occurrence of agitated depression in bipolar I disorder is not rare and has significant prognostic and therapeutic implications. Whether the co-occurrence of a major depressive syndrome with one or two of these symptomatic clusters makes up a "mixed state" remains unclear.

The prognostic significance of "switching" in patients with bipolar disorder: a 10-year prospective follow-up study.

OBJECTIVE: This study explored whether "switching" (i.e., the direct transition from one mood polarity to the other) has significant prognostic implications in patients with bipolar disorder. METHOD: Bipolar disorder patients (N=97) whose first prospectively observed episode included at least one mood polarity switch and 97 bipolar disorder patients whose index episode was monophasic were compared with respect to several demographic and historical variables, symptomatic features of the index episode, time to recovery from the index episode, time spent in an affective episode during a prospective observation period, and psychopathological and psychosocial outcome at a 10-year follow-up interview. RESULTS: Patients whose index episode included at least two mood polarity switches spent significantly more time in an affective episode during the observation period and had a significantly worse psychopathological and psychosocial outcome 10 years after recruitment than those whose index episode included only one mood polarity switch or was monophasic. Patients whose polyphasic index episode started with depression spent a significantly higher proportion of time in an affective episode and had a significantly worse 10-year outcome than those whose polyphasic index episode started with mania or hypomania. Retention of the switching pattern throughout the observation period was seen in 42.4% of patients whose index episode started with mania and in 65.2% of those whose index episode started with depression. CONCLUSIONS: An index episode including at least two mood polarity switches, especially if starting with depression, is associated with a poor long-term outcome in patients with bipolar disorder. This pattern represents a significant target for new pharmacological and psychosocial treatment strategies.

Long-term outcome of lithium prophylaxis in bipolar disorder with mood-incongruent psychotic features: a prospective study.

BACKGROUND: No study has assessed systematically up to now the long-term outcome of lithium prophylaxis in bipolar patients with vs. without mood-incongruent psychotic features. METHODS: All bipolar patients with mood-incongruent psychotic features who started lithium prophylaxis at a lithium clinic during 14 years were followed up prospectively for 5 years, along with a control group of non-psychotic bipolars. RESULTS: Psychotic patients were significantly less likely than controls to be still on lithium after 5 years, and to present a reduction of at least 50% of time spent in hospital during the lithium treatment period compared with a pre-treatment period of the same duration. The time to 50% risk of readmission was significantly increased among both groups during lithium treatment. 39.6% of prospective episodes in psychotic patients did not include mood-incongruent psychotic features. LIMITATIONS: This is a naturalistic study carried out at a lithium clinic. No control group of bipolar patients who did not receive lithium was available. CONCLUSIONS: Lithium exerts a significant impact on the course of bipolar disorder with mood-incongruent psychotic features, although this impact is less pronounced than in classical manic-depressive illness.
