Role of TachoSil® in distal pancreatectomy: a single center experience.

AIM: Distal pancreatectomies (DP) are associated with high risk of postoperative complications, and in many series higher morbidity rate than duodenopancreatectomies has been reported. To evaluate the role of a collagen sponge with human fibrinogen and thrombin film (TachoSil®) in limiting the incidence of complications after DP. METHODS: From 1996 to 2013, 221 patients have been submitted to distal pancreatectomy (± splenectomy) in our Division. A retrospective analysis has been conducted in a group of 36 consecutive and prospectively collected DP treated with intraoperative placement of TachoSil® on pancreatic stump from 2010 to 2013 (group 1). A control series of 36 consecutive patients (group 2) was matched 1:1 from hystorical database. The variables considered in the analysis were: age, gender, ASA score, pancreatic texture (hard vs. soft), histology, operative time, postoperative mortality, morbility (postoperative pancreatic fistula - POPF, postoperative hemorrage - PPH, delayed gastric emptying - DGE) and hospital stay. Differences between POPF, PPH, DGE and hospital stays between grops were investigated with χ² and t-Student test. Univariate analysis was conducted to determine factors related to POPF development. Statistical analysis was performed using freeware Microsoft Excel based program. RESULTS: Post operative mortality was 0% in both groups. POPF were registered in 36.1% (13/36) and 41.6 % (15/36) in groups 1 and 2, respectively (P=n.s.); in group 1 we didn't observe grade C POPF, while 4 patients in control group developed grade C POPF (P<0,05). No differences were found between two groups in terms of incidence of PPH and DGE. The median duration of postoperative hospital stay in group 1 was 21.8 (7-189) days compared with 31.13 (9-249) days in group 2 (P<0.001). CONCLUSION: The use of TachoSil® seems to be associated with lower incidence of grade C POPF but larger controlled trials are needed to surely assess the usefulness of TachoSil® in pancreatic surgery in order to reduce pancreatic specific complications and their severity.

[Congenital Milroy Oedema: a case report of a family]. / Edema congenito di Milroy. descrizione di una famiglia.

The authors describe the case of a newborn and their family with Nonne-Milroy disease (hereditary lymphedema type I), a genetic disease that is usually characterized by lymphedema, that most often affects the lower extremities or less frequently the back of the hands. We discuss etiology, inheritance pattern, differential diagnosis and follow-up.

"Shades of Gray" in pancreatic ductal adenocarcinoma: Reappraisals on resectability criteria: Debated indications for surgery in pancreatic cancer.

Pancreatic ductal adenocarcinoma is one of the leading causes of cancer-related deaths and, currently, surgery is the only curative treatment. Patients with borderline resectable pancreatic cancer (BRPC) can benefit from a multidisciplinary approach and R0 resection, and can achieve the same outcome as resectable patients treated with upfront surgery. However, the definition of BRPC changes according to different classifications with a heterogeneous distribution of patients, and it is thus difficult to compare clinical evidence. We performed a literature review to assess the most suitable classification of BRPC. Our review was conducted using the PubMed database. Only articles containing more than ten patients classified according to NCCN, MDACC or AHPBA/SSAT/SSO classifications were selected. A total of 16 studies were included in our analysis, and were grouped according to one of these three classifications. The total resection rate was 61.4%, with considerable differences between the groups (68.4% for NCCN, 54.9% for MDACC and 53.2% for AHPBA/SSO/SSAT). The total R0 resection rate was 90.1% (89.1% for NCCN, 92.5% for MDACC and 84% for AHPBA/SSO/SSAT). Of the three classifications, NCCN limits the use of confusing terms and uses restrictive criteria to define the most appropriate treatment for each subgroup. However, several reports have suggested that, even in the case of a limited disease, biological and clinical factors should be considered in order to classify patients as resectable. NCCN classification appears to be the classification that allows the highest percentage of patients with BRPC to achieve resection without reducing the R0 resection rate. The choice of therapy should not only be based on imaging results, but also on a wider clinical multidisciplinary evaluation.

[Role of EUS in a diagnostic and staging algorithm of pancreatic carcinoma: the surgeon point of view]. / Il ruolo dell'EUS in un algoritmo diagnostico-stadiativo del carcinoma pancreatico: il punto di vista del chirurgo.

Survival of pancreatic cancer is improved by surgery and is related to R0 resection. An accurate diagnosis and a careful staging are mandatory. Differential diagnosis must be estabilished between the different pancreatic lesions as carcinoma, chronic pancreatitis, cystic or endocrine neoplasms. Endoscopic ultrasound (EUS) is the best technique for diagnosis and allows cytological examination by fine needle aspiration (FNA). Preoperative resectability is defined by EUS in borderline tumors. EUS is a useful procedure for the surgical strategy of pancreatic cancer.

Preoperative oral immunonutrition versus standard preoperative oral diet in well nourished patients undergoing pancreaticoduodenectomy.

BACKGROUND: Pancreaticoduodenectomy is still associated to high morbility, especially due to pancreatic surgery related and infectious complications: many risk factors have already been advocated. Aim of this study is to evaluate the role of preoperative oral immunonutrition in well nourished patients scheduled for pancreaticoduodenectomy. METHODS: From February 2014 to June 2015, 54 well nourished patients undergoing pancreaticoduodenectomy were enrolled for 5 days preoperative oral immunonutrition. A series of consecutive patients submitted to the same intervention in the same department, with preoperative standard oral diet, was matched 1:1. For analysis demographic, pathological and surgical variables were considered. Mortality rate, overall postoperative morbility, pancreatic fistula, post pancreatectomy haemorrhage, delayed gastric emptying, infectious complications and length of hospital stay were described for each groups. Chi squared test, Fisher's Exact test and Student's T test were used for comparison. Differences were considered statistically significant at p < 0.05. Statistics was performed using a freeware Microsoft Excel (®) based program and SPSS v 10.00. RESULTS: No statistical differences in term of mortality (2.1% in each groups) and overall morbility rate (41.6% vs 47.9%) occurred between the groups as well as for pancreatic surgery related complications. Conversely, statistical differences were found for infectious complications (22.9% vs 43.7%, p = 0.034) and length of hospital stay (18.3 ± 6.8 days vs 21.7 ± 8.3, p = 0.035) in immunonutrition group. CONCLUSION: Preoperative oral immunonutrition is effective for well nourished patients scheduled for pancreaticoduodenectomy; it helps to reduce the risk of postoperative infectious complications and length of hospital stays.

[Sleeping in the supine position in the ASL 11 region of Piemonte. Assessment of the efficacy of a promotional campaign]. / Dormire sulla schiena nell'asl 11--regione Piemonte Valutazione dell'efficacia di una campagna promozionale.

OBJECTIVES: To record the prevalence of the sleeping position of sucklings living in the ASL 11-Regione Piemonte; to make an information campaign about the utility of sleeping in the supine position (most important protection factor against the SIDS); to find out its efficacy for a short or long time. METHODS: During the first two months of 2002 all the parents coming to the consulting rooms for the compulsory vaccinations of their 3 and 5 months old babies have been interviewed about the position of their babies during sleep. The same recording has been made in the first two months of 2003 and 2004. During 2002 various consciousness campaigns have been made, above all for medical operators of hospital nurseries and of Mother-and-Child Departments and Prevention Departments in ASL 11 area. RESULTS: Before the consciousness campaign the percentage of 3 months old sucklings sleeping in the supine position was 62,3% and 55% for the 5 months old suckings; after the campaign the percentage has grown to 77,4% for 3 months old sucklings and 74,5% for 5 months old sucklings during 2003 and during 2004 the percentage has grown to 80,3% and 74,2%, respectively. CONCLUSIONS: A simple and not expensive but capillary consciousness and information campaign addressed to medical operators has obtained valid and statistically relevant results in a short time.

Thyroid autoimmunity: really an important cause of sporadic congenital hypothyroidism?

The transplacental transfer of maternal antithyroid antibodies has recently been hypothesised as an aetiological factor in CH. In order to test this hypothesis, mothers and newborns identified by neonatal screening as suffering from hypothyroidism were tested for TgAb, MAb and TSHBAb. Significant titres of MAb and TgAb antibodies were found in 5% of the newborns and their mothers. TSHBAb was found in 1 out of 18 newborns and 1 out of 14 mothers. A causal link was found between the transplacental transfer of IgG inhibiting thyroid growth and function induced by TSH from a mother with Hashimoto's thyroiditis a newborn with CH and in her CH newborn. However the present series did not reveal the high percentage of cases with CH and thyroid antibodies reported by others and particularly not among the neonates born to mothers without any kind of maternal thyroid pathology. It therefore seems that the role of autoimmunity in the pathogenesis of CH and TH is yet to be clarified.

[Role of surgery in the multidisciplinary treatment of lithiasis of the common bile duct]. / Il ruolo della chirurgia nel trattamento multidisciplinare della litiasi della via biliare principale (VBP).

The efficacy of surgery was evaluated in 32 patients with common bile duct stones. Twenty-two patients have not undergone a previous cholecystectomy. In 13 cases an endoscopic approach was attempted before surgery. In 13 patients biliary-intestinal anastomoses were performed for large stones or bile duct strictures. In 19 cases common bile exploration with biliary drainage insertion was performed for uncomplicated biliary stones. We had no mortality and morbidity was 9%. We conclude that surgery is the treatment of choice in patients with gallbladder in situ or in cases of endoscopic failure. Endoscopic sphincterectomy may be preferred in poor-risk patients.

[Groove pancreatitis. A case report of chronic focal pancreatitis]. / La "groove pancreatitis". Descrizione di un caso di pancreatite cronica focale.

The "groove pancreatitis" is a special form of segmental chronic pancreatitis affecting the "groove" between pancreatic head, duodenum and common bile duct. This type of chronic pancreatitis was first described in 1973 and only few cases have been reported in literature. Unlike other forms of chronic pancreatitis, this is often preceded by peptic ulcers, gastric resections or biliary tract diseases; it could be associated with cysts of the duodenal wall and pancreatic cysts. Abdominal pain, vomiting due to duodenal stenosis, obstructive jaundice and weight loss are the most common presenting symptoms. The radiological features show a pancreatic mass similar to a pancreatic head carcinoma and the discrimination of groove pancreatitis from pancreatic carcinoma is often difficult or even impossible in some patients. We describe a case of groove pancreatitis treated with pancreatoduodenectomy, reviewing the clinical and radiological features. We remark that the groove pancreatitis is a disease that must be known and should be considered in the differential diagnosis of pancreatic carcinoma.

[Endoscopic therapy of giant choledochal calculosis]. / Terapia endoscopica della calcolosi coledocica gigante.

The paper reports the results of conventional endoscopic treatment in 100 consecutive cases of giant lithiasis of the common bile duct. A giant calculus is one whose dimensions exceed 2 cm. Endoscopic therapy proved successful in 73% of cases, with an 8% incidence of complications. The success of endoscopic treatment is related to the anatomical conditions of the biliary tract and the diameter of calculi. Mechanical lithotripsy has proved efficacious in all cases where it was used, whereas poor results were obtained using MTBE infusion through a naso-biliary tube. ESWL provided encouraging results. Cases which were not resolved using endoscopic methods were treated using intervention radiology or surgery, or both.

[Postoperative pain management: epidural analgesia]. / Controllo del dolore postoperatorio: la via peridurale.

BACKGROUND: Epidural analgesia is one of the most effective regimens for postoperative pain relief after abdominal surgery. The use of epidural analgesia in high risk patients has been associated with significant decrease in surgical stress response, in cardiac and pulmonary morbidity, in recovery of gastrointestinal function and in thromboembolic events. The aim of this paper is to describe pain relief, side effects and recovery of gastrointestinal function during epidural analgesia. METHODS: During the period January 1999 to September 2001, 590 patients undergoing elective major abdominal surgery received epidural analgesia. Epidural catheters were inserted at T8-T9 (upper abdominal surgery) or T9-T11 (lower abdominal surgery) and ropivacaine 0.5% ml 7-12 combined with sufentanil 30 microg or with morphine 2 mg was injected. General anesthesia was induced and a continuous epidural infusion of ropivacaine 0.5% 5-10 ml/h was begun. Postoperatively, continuous epidural administration of ropivacaine 0.2% plus sufentanil 0.5 microg/ml or ropivacaine 0.2% plus morphine 0.02 mg/ml was continued. Data on the quality of analgesia, recovery of gastrointestinal function and all side effects were recorded for 4 days. RESULTS: Resting and incident pain scores were <4 and <5; 20% of patients received a rescue dose; the incidence of nausea was 6%, pruritus 5%; all patients also recovered from postoperative ileus. CONCLUSIONS: Continuous epidural analgesia resulted in good pain relief, provided the best balance of analgesia and side effects and improved postoperative outcome.

[The functional and manometric results of 2 surgical methods of posterior abdominal rectopexy]. / Risultati funzionali e manometrici di due metodi chirurgici di rettopessi addominale posteriore.

Functional changes after posterior abdominal rectopexy for the treatment of rectal prolapse are not fully understood. We studied the effects of Wells' or Ripstein's rectopexy on functional characteristics as related to anal sphincter function, rectal volume and sensory function in 31 patients with complete or internal rectal prolapse. We have observed an improvement of continence over 70% in both groups. However, an absent or a decreased call to stool, constipation and evacuation difficulties are the aftermath of Wells' rectopexy, while these complaints appear basically unaffected by Ripstein's technique. Maximal squeeze pressure was slightly increased after Ripstein's rectopexy, whereas no significant effects were found on anal pressures. Postoperatively the rectal capacity was reduced by Well's procedure (p < 0.05), while no significant changes were observed with Ripstein's operation. After the Wells procedure patients developed at the threshold for the relaxation of the internal sphincter progressively lower rectal volumes, reaching one year after rectopexy the statistical significance. Sensory thresholds for sense of filling and urge were significantly raised after Wells' rectopexy even one year after operation, whereas after Ripstein's operation sense of filling was not significantly affected and while sense of urge was increased early postoperatively, it was not significantly changed at one hear postoperative control. In conclusion, when fecal incontinence appears associated to a rectal prolapse has good chances to improve postoperatively. Preoperative evacuation difficulties seem to be unaffected by a posterior abdominal rectopexy, Wells or Ripstein, but an extensive dissection of the rectum with the division of the lateral stalks, as it is performed in Wells' operation, seems to be a procedure that can create a further burden of problems the the patient and it seems coupled to a manovolumetric elevation of rectal sensory thresholds.

[Variations in rectal capacity and compliance after abdominal rectopexy]. / Variazione della capacità e della compliance rettale dopo rettopessia addominale.

The aim of this study was to attempt to gain insight in to the pathophysiologic characteristics of rectal prolapse by evaluating rectal compliance in patients with complete or incomplete rectal prolapse, before and after rectopexy. 21 subjects with complete rectal prolapse and 10 subjects with internal procidentia of rectum were treated with one of two abdominal rectopexies, according to Wells or according to a modified Ripstein's technique. For comparison, measurements were also carried out in 17 age and sex control subjects who had no bowel disturbances or anal symptoms. On distension with 40 cm H2O rectal volume amounted to 218 (175-255) ml for controls, 225 (178-256) ml for complete prolapses and 200 (125-225) ml for invaginations. Compliance amounted respectively to 9.5 (5-11,4), 8.5 (5-12,6), 7.5 (4-10,6) ml/cm H2O in the pressure interval 0-10 cm H2O with a decrease in compliance at higher pressure intervals. There was no correlation between rectal volume and compliance and gas or faecal incontinence, evacuation difficulties, feeling of blockade upon defecation and constipation. The effect of rectopexy has been separately evaluated according to the diagnosis. In complete prolapse significant changes of rectal capacity were observed for lower distending pressures (from 10 to 30), but not for higher (40-50). The compliance was significantly different for even lower distending pressures (0-10 cm H2O). In internal rectal procidentia rectopexy did not significantly changed capacity compliance. This work confirms the observations that the rectal compliance in rectal prolapse, complete and incomplete, do not differ from healthy controls.(ABSTRACT TRUNCATED AT 250 WORDS)

[Evaluation of the sphincter function and rectal sensitivity in rectal prolapse associated with fecal incontinence]. / Valutazione della funzione sfinterica e della sensibilità rettale nel prolasso del retto associato ad incontinenza fecale.

It has been suggested that incontinent patients with rectal prolapse develop a relaxation of the internal sphincter at a lower filling volume than those with the same disorder who were continent. A constant relaxation of the internal sphincter during filling before the individual experiences a need to defecate could be a contributory cause of the incontinence in these patients. Aiming to evaluate the former observations we have investigated continent and incontinent patients, with complete and internal rectal prolapse, by mean of the recto-anal manovolumetry. 31 patients were studied, 21 had a complete rectal prolapse and 10 had internal rectal prolapse and 28 sex and age matched controls were selected among volunteers. No difference has been found between the continent and incontinent patients with rectal prolapse, in term of sensory function studied by graded isobaric distention. Moreover, no difference has been found between the rectal volume at which perception of filling and relaxation of the internal sphincter during filling occurs. Therefore, in this respect, the present data are not in agreement with the theory proposed.

[What shall I eat today? Survey about dietary habits of infants and toddlers in Valsesia]. / Cosa mangio oggi? Indagine sulle abitudini alimentari dei bambini fino a tre anni in Valsesia.

In April 2002 a survey was conducted about dietary habits of infants and toddlers attending kindergartens in Valsesia, through dietary journal compilation. From 149 answers (response rate = 70%) the results are: a limited vegetables consumption, with a potatoes excess and a legumes scarcity; only one half of children eats fruits daily; consumption of ham and cheese is higher than other proteinic foods; foods variety is weak and the menu is often repetitive in lunch and dinner.

[Opinions and attitudes of youngsters about sexually transmitted diseases]. / Cosa pensano i giovani delle malattie sessualmente trasmesse (Indagine conoscitiva su 1.085 studenti valsesiani).

A group of 1.085 students (582 M, 503 F) attending high school (742) and nursing school (343) filled in an anonymous questionnaire on their sexual habits and their knowledge of contraception and sexually transmitted diseases. Overall, 57% of the study population had already a complete sexual intercourse at a mean age of 16,4 (SD +/- 1,8). 74% had 1-3 sexual partners, whereas 28% had more than 3. All students affirmed that it was possible to prevent sexually transmitted diseases and 92,6% indicated correct methods. However 10% of students did not know that AIDS is transmitted sexually as 47% hepatitis B. The responses made by nursing students were more correct that those of high school students.

[Defects of thyroid hormone synthesis: nosographic study and proposal for a protocol for differential diagnosis]. / Difetti dell'ormonogenesi tiroidea: inquadramento nosografico e proposta di un protocollo di diagnosi differenziale.

In addition to the forms of congenital hypothyroidism caused by dysgenesis of the thyroid gland (agenesia, ectopy), this phenomenon may be caused by enzyme deficiencies of the thyroid hormone synthetic process. These defects, which are hereditary and transmitted as recessive autosomic characters, are clinically manifest in homozygotic subjects in the form of goitres which appears during the neonatal age or, as in more common, during later infancy. At present, mass neonatal screening allows this phenomenon to be diagnosed during the first days of life. The diagnosis of hypothyroidism caused by enzyme deficiency is made on the basis of radioisotopic and ultrasonic studies, and by the assay of plasma levels of thyroglobulin. The exact definition of the specific enzyme activity which is lacking in each case is more complex and has still to be resolved. This study describes the biochemical and pathogenetic characteristics of the different thyroid hormone synthesis defects and includes the findings of previously published diagnosis tests in order to identify the missing enzymatic activity. Lastly, a protocol for the differential diagnosis of the various types of defect is outlined. A specific etiological definition of the altered thyroid metabolism, while providing further insight into the physiopathology of the thyroid and the epidemiology of enzymatic hormone synthesis defects, should not be a motive for delaying the start of substitutive therapy at the earliest possible stage.

[Herpetic encephalitis with biphasic course. A case report and review of the literature]. / Encefalite erpetica a decorso bifasico. Descrizione di un caso e revisione della letteratura.

Encephalitis represents an important event in pediatric practice. Between the different causes Herpes Simplex Virus (HSV) seems to be the most significant etiological agent, not only for its frequency but chiefly for conditioning prognosis. The Authors report a new case of HSV encephalitis with biphasic course illustrating the most recent pathologic, diagnostic and therapeutic features in the attempt to individualize those factors, between clinical data, laboratory findings and imaging that allow early diagnosis and consequently precocious specific antiviral therapy.
