Umbilicus Necrosis During Mesh Repair of Rectus Diastasis for Abdominoplasty: Practical Tips for Prevention and Treatment.

Rectus muscles widened by pregnancy are handled in dramatically different ways in standard abdominoplasty and mesh abdominoplasty. Patients with significant abdominal wall laxity and/or umbilical hernia repair are treated with the use of retrorectus mesh placement. In these conditions the risk of damaging the blood supply to the umbilicus might be greater. Despite the fact that it is of no functional significance in adults, the umbilicus is a key esthetic landmark of the anterior abdominal wall. For both patients and surgeons alike, its absence, distortion, or misplacement after surgery can be distressing and can be a source of frequent patient complaint. Umbilical stalk necrosis represents an underreported yet important complication for patients following mesh abdominoplasty. We advance some recommendations for patients undergoing abdominoplasty with mesh repair of rectus diastasis and/or concomitant umbilical hernia mesh repair via the open approach. This information should help influence intraoperative decision-making to prevent the development of this undesirable complication.Level of Evidence V: This journal requires that authors assign a level of evidence to each article.

Sutureless Repair for Open Treatment of Inguinal Hernia: Three Techniques in Comparison.

Currently, groin hernia repair is mostly performed with application of mesh prostheses fixed with or without suture. However, views on safety and efficacy of different surgical approaches are still partly discordant. In this multicentre retrospective study, three sutureless procedures, i.e., mesh fixation with glue, application of self-gripping mesh, and Trabucco's technique, were compared in 1034 patients with primary unilateral non-complicated inguinal hernia subjected to open anterior surgery. Patient-related features, comorbidities, and drugs potentially affecting the intervention outcomes were also examined. The incidence of postoperative complications, acute and chronic pain, and time until discharge were assessed. A multivariate logistic regression was used to compare the odds ratio of the surgical techniques adjusting for other risk factors. The application of standard/heavy mesh, performed in the Trabucco's technique, was found to significantly increase the odds ratio of hematomas (p = 0.014) and, most notably, of acute postoperative pain (p < 0.001). Among the clinical parameters, antithrombotic therapy and large hernia size were independent risk factors for hematomas and longer hospital stay, whilst small hernias were an independent predictor of pain. Overall, our findings suggest that the Trabucco's technique should not be preferred in patients with a large hernia and on antithrombotic therapy.

Internal hernia after an open gastrectomy: an unusual treatment approach and a systematic review of the literature.

Internal hernia (IH) is a serious complication that can occur after both laparoscopic and open surgery for the treatment of gastric cancer; the transverse colon and mesocolon, act as a natural partition between stomach and the small intestine and, once any type of gastrojejunal anastomosis is constructed, a potential space for internal hernia is created. We present the case of a 68-year-old patient diagnosed with intestinal ischemia due to an IH in the site of the jejunojejunostomy after an open gastrectomy for gastric cancer, treated with negative wound pressure therapy (NWPT) on open abdomen (ABTHERATM dressing).

A rare case of duplication of the descending colon in a pregnant woman: case report and literature review.

INTRODUCTION: Gastrointestinal duplications are uncommon congenital abnormalities that can occur anywhere throughout the intestinal tract. The small bowel is more interested than the large one. Duplications are schematically classified as spherical and tubular, respectively representing 80% and 20% of cases, with different relationships and communications with the native intestinal wall. Although typically diagnosed during infancy and early childhood, tubular colonic sub-type stays frequently hidden for several years until a complication occurs. CASE PRESENTATION: we report the case of a T-shaped tubular duplication in a 20-year-old woman at the 30th week of gestation, who underwent an urgent exploratory laparotomy for intestinal occlusion, treated with the resection of the aberrant large bowel. The patient was notable for a long history of constipation and chronic pain. Diagnostic possibilities were limited by the on-going pregnancy. CONCLUSION: Intestinal duplications are uncommon malformations, and, of these, the T-shaped subtype of the colon is among the rarest ones. In the adulthood, diagnosis is usually established in the operating room during urgent or even emergency surgery performed for abdominal complications. A duplication of the descending colon is extremely rare, and this is, to our knowledge, the only article describing a case found in advanced state of pregnancy.

Pediatric ultrasound-guided dorsal penile nerve block and sedation in spontaneous breathing: a prospective observational study.

Background: Worldwide, one of the most common surgical procedures in the pediatric population is circumcision. There is no consent on the best anesthesiologic approach. This study aimed to investigate ultrasound-guided dorsal penile nerve block (DPNB) plus sedation in spontaneous breathing as a time-saving, safe, effective, and opioid-sparing technique. Aims: The primary outcome was the assessment of the time from the end of surgery and the discharge to the post-anesthesia care unit. Secondary outcomes were to evaluate the cumulative dosages of opioids, differences in pain levels between the two groups, and complications at the awakening, 4 h and 72 h after surgery, respectively. Methods: This was a prospective study with a retrospective control group, approved by the Friuli-Venezia Giulia Ethics Committee. Children in the intervention group received an ultrasound-guided DPNB under sedation and spontaneous breathing. With the probe positioned transversally at the base of the penis using an in-plane approach with a modified technique, local anesthetic was injected under the deep fascia of the penis. Results: We recruited 70 children who underwent circumcision at the University Hospital of Udine, Italy, from 1 January 2016 to 1 October 2021: 35 children in the ultrasound-guided DPNB group and 35 children in the control group. Children who received ultrasound-guided DPNB had a statistically significant lower time to discharge from the operating room, did not require mechanical ventilation, maintained spontaneous breathing at all times, received fewer opioids, had lower mean intraoperative arterial pressures, and lower pain levels immediately after surgery. Conclusion: Ultrasound-guided DPNB associated with sedation and spontaneous breathing is a time-saving, opioid-sparing, safe, and effective strategy for the management of intraoperative and postoperative pain in children undergoing circumcision.Clinical trial registration: ClinicalTrial.gov (NCT04475458, 17 July 2020).

A Rare Case of Hepatocellular Carcinoma Recurrence in Ovarian Site after 12 Years Mimicking a Hepatoid Adenocarcinoma: Case Report.

Hepatoid carcinoma of the ovary (HCO) is a tumor that resembles, both histologically and cytologically, hepatocarcinoma (HCC) in a patient with a non-cirrhotic liver not involved by the disease. Hepatoid carcinoma is an extremely rare histologic subtype of ovarian cancer and should be distinguished from metastatic HCC. Here, we report the rare case of a 67-year-old woman with ovarian recurrence of HCC 12 years after first diagnosis. The patient was being followed by oncologists because she had been diagnosed with HCV-related HCC (Edmonson and Stainer grade 2, pT2 N0 M0, G2, V1) in 2009. She had undergone surgery for enlarged left hepatectomy to the 4th hepatic segment with cholecystectomy and subsequent placement of a Kehr drain. The preoperative alpha-fetoprotein (AFP) level was 8600 ng/mL, while the postoperative value was only 2.7 ng/mL. At the first diagnosis, no other localizations of the disease, including the genital tract, were found. At the time of recurrence, however, the patient was completely asymptomatic: her liver function was within normal limits with negative blood indices, except for an increased blood dosage of AFP (467 ng/mL), and CA125, which became borderline (37.4 IU/mL). The oncologist placed an indication for a thoracic abdominal CT scan, which showed that the residual liver was free of disease, and the presence of a formation with a solid-cystic appearance and some calcifications at the left adnexal site. The radiological findings were confirmed on level II gynecological ultrasound. The patient then underwent a radical surgery of hysterectomy, bilateral oophorectomy, pelvic peritonectomy, and omentectomy by a laparotomic approach, with the sending of intraoperative extemporaneous histological examination on the annexus site of the tumor mass, obtaining RT = 0. Currently, the patient continues her gyneco-oncology follow-up simultaneously clinically, in laboratory, and instrumentally every 4 months. Our study currently represents the longest elapsed time interval between first diagnosis and disease recurrence, as evidenced by current data in the literature. This was a rather unique and difficult clinical case because of the rarity of the disease, the lack of scientific evidence, and the difficulty in differentiating the primary hepatoid phenotype of the ovary from an ovarian metastasis of HCC. Several multidisciplinary meetings for proper interpretation of clinical and anamnestic data, with the aid of immunohistochemistry (IHC) on histological slides were essential for case management.

Morgagni hernia: technical variation in the laparoscopic treatment.

INTRODUCTION: Morgagni hernia is a rare entity that accounts for 3-5% of diaphragmatic hernias. They are mostly asymptomatic and discovered incidentally. Surgical treatment is indicated once diagnosis is made. Abdominal or thoracic accesses are possible using open or minimally invasive technique. METHODS: We report two cases of laparoscopic assisted repair of Morgagni hernia conducted by primary closure of the diaphragmatic defect with extracorporeal nonabsorbable sutures anchoring the diaphragmatic edge at the muscular fascia of the abdominal wall. RESULTS: Both patients had an uneventful postoperative recovery. The operative time was 90 and 60 minutes and the postoperative hospitalization was 4 and 2 days respectively. CONCLUSIONS: Laparoscopic intervention for Morgagni hernia repair is easy, safe and less invasive compared to the open one, with reduced hospitalization time. Primary closure of the diaphragmatic defect with extracorporeal nonabsorbable sutures is an effective technique for Morgagni hernia; defects larger than 20-30 cm2 should be repaired using a prosthetic patch.

Open Surgery for Sportsman's Hernia a Retrospective Study.

Sportsman's hernia is a painful syndrome in the inguinal area occurring in patients who play sports at an amatorial or professional level. Pain arises during sport, and sometimes persists after activity, representing an obstacle to sport resumption. A laparoscopic/endoscopic approach is proposed by many authors for treatment of the inguinal wall defect. Aim of this study is to assess the open technique in terms of safety and effectiveness, in order to obtain the benefit of an open treatment in an outpatient management. From October 2017 to July 2019, 34 patients underwent surgery for groin pain syndrome. All cases exhibited a bulging of the inguinal posterior wall. 14 patients were treated with Lichtenstein technique with transversalis fascia plication and placement of a polypropylene mesh fixed with fibrin glue. In 20 cases, a polypropylene mesh was placed in the preperitoneal space. The procedure was performed in day surgery facilities. Early or late postoperative complications did not occur in both groups. All patients returned to sport, in 32 cases with complete pain relief, whereas 2 patients experienced mild residual pain. The average value of return to sport was 34.11 ± 8.44 days. The average value of return to play was 53.82 ± 11.69 days. With regard to postoperative pain, no substantial differences between the two techniques were detected, and good results in terms of the resumption of sport were ensured in both groups. Surgical treatment for sportsman's hernia should be considered only after the failure of conservative treatment. The open technique is safe and allows a rapid postoperative recovery.

Incidental pancreatic cysts on 3D turbo spin echo magnetic resonance cholangiopancreatography: prevalence and relation with clinical and imaging features.

PURPOSE: To estimate the prevalence of incidental pancreatic cysts (IPCs) in asymptomatic patients addressed to magnetic resonance cholangiopancreatography (MRCP), and to correlate it with clinical and imaging features. MATERIALS AND METHODS: Magnetic resonance cholangiopancreatography performed over 26-months on 152 patients with unsuspected/unknown pancreatic disease were reviewed to assess IPCs' features of presentation. Multivariate analysis was performed to evaluate the correlation of IPCs with clinical information and type of pancreaticobiliary findings at MRCP. RESULTS: Prevalence of IPCs was 44.7%. Cysts sized 3-24 mm (mean, 6.08 mm), and were ≤4 in number in 83.8% of patients. Based on number, dimensions and relation with the main pancreatic duct, IPCs presented with intraductal-papillary-mucinous neoplasm (IPMN)-like or indeterminate patterns in 31.7% and 13.1% of patients, respectively. At follow-up on 24 patients, no evolution was found, except in one patient with proven IPMN showing increase in cysts number and dimensions (evolution rate of 4.1%). Features correlating with IPCs were age ≥60 years old, and history of autoimmune hepatobiliary disease, showing odds ratios of 5.95 (95% CI 2.77-12.79) and 0.13 (95% CI 0.04-0.44), respectively. CONCLUSIONS: Incidental pancreatic cysts represent a frequent finding at MRCP, correlating positively with increasing age, and negatively with biliary autoimmune disease. Cysts more frequently present with IPMN-like pattern.

Recommendations for outpatient activity in COVID-19 pandemic.

The spread of the COVID-19 disease substantially influenced the International Healthcare system, and the national governments worldwide had before long to decide how to manage the available resources, giving priority to the treatment of the COVID-infected patients. Then, in many countries, it was decided to limit the elective procedures to surgical oncology and emergency procedures. In fact, most of the routine, middle-low complexity surgical interventions were reduced, and the day surgery (DS) activities were almost totally interrupted. As a result of this approach, the waiting list of these patients has significantly increased. In the current phase, with a significant decrease in the incidence of COVID-19 cases, the surgical daily activity can be safely and effectively restarted. Adjustments are mandatory to resume the DS activity. The whole separation of pathways with respect to the long-stay and emergency surgery, an accurate preoperative protocol of patient management, with a proper selection and screening of all-day cases, careful scheduling of surgical organization in the operating room, and planning of the postoperative pathway are the goals for a feasible, safe, and effective resumption of DS activity.

Incidental pancreatic cysts: a frequent finding in liver-transplanted patients as assessed by 3D T2-weighted turbo spin echo magnetic resonance cholangiopancreatography.

CONTEXT: The increasing frequency of incidental pancreatic cysts at imaging is a challenging topic due to the uncertainty of the aggressiveness of these lesions, especially small ones. To date, no data exist about their prevalence in a population of liver-transplanted patients. OBJECTIVE: To determine the prevalence of incidental pancreatic cysts in liver-transplanted patients using magnetic resonance cholangiopancreatography. DESIGN: A retrospective, single center case series. SETTING: A tertiary referral centre. Interventions and patients Seventy-two examinations were performed over a two-year period in 47 liver-transplanted patients suspected for biliary complications. MAIN OUTCOME MEASURES: Prevalence of incidental pancreatic cysts; proportion of cyst evolution over time; association of cysts with clinical and imaging features. RESULTS: The prevalence of pancreatic cysts was 59.6%. Analysis showed a mean diameter of 5.4 mm and the presence of 1-3 cysts in 78.6% of patients (22/28). Communication with the main pancreatic duct was identified for 28 relatively larger cysts (up to 14 mm) in 14 subjects. An "intraductal papillary mucinous neoplasia-like pattern" was observed in 12 patients with cysts, based on the number of cysts, dimensions, and distribution. Out of the 15 patients who underwent additional MRCPs to monitor biliary findings, only one patient with proven intraductal papillary mucinous neoplasia showed modification of the cysts at follow-up. Among the evaluated pre- or post-transplantation factors (sex, age, etiology of cirrhosis, pre-transplant hepatocarcinoma, pancreatic abnormalities other than cysts, type of pancreaticobiliary channel/biliary anastomosis, presence of biliary complications, lithiasic biliary complications, transplant-examination interval), only the alcoholic etiology of cirrhosis was associated with the prevalence of pancreatic cysts (P=0.006). CONCLUSIONS: Incidental pancreatic cysts are frequent in liver-transplanted patients. Clinical significance, relation to transplant, impact on patient management before and after transplant are still under debate and a matter for further investigation.

The role of pancreatic leakage on rising of postoperative complications following pancreatic surgery.

INTRODUCTION: The variations in methods of pancreatic stump management and the volume of literature available on both main pancreatic duct and pancreaticoenetric anastomosis leak indicates the concern associated with the leak and the continuing efforts to prevent it. Herein we analyzed the role of pancreatic leakage followed by pancreatic surgery on the incidence of postoperative morbidity. PATIENTS AND METHODS: From 1989 to 2005, we performed 76 pancreaticoduodenectomy (PD) and 26 distal pancreatectomy (DP), assumed as control case). During DP the parenchymal transection was performed with a linear stapler. The surgical reconstruction after PD was as follows: 11 manual nonabsorbable stitch closure of the main duct, 24 closure of the main duct with linear stapler, 17 temporary occlusion of the main duct with neoprene glue, and 24 duct-to-mucosa anastomosis. RESULTS: In the PD group, morbidity rate was 60%, caused by pancreatic leakage, with an incidence of 48%, hemorrhagic complication, occurred in 10% of patients following surgical procedure and infectious complication, with an incidence of 15%. After distal pancreatectomy we recorded 80, 7% no complications, 3, 9% leakage, 15, 4% hemoperitoneum. By multivariate analysis bleeding complications, biliary anastomosis leakage, and infectious complications were consequences of pancreatic leakage (P = 0.025, P = 0.025, and P = 0.025, respectively). A significant statistical difference was recorded analyzing re-operation rates between closure of the main duct with linear stapler versus temporary occlusion of the main duct with neoprene glue (t = 0.049) and closure of the main duct with linear stapler versus duct-to-mucosa anastomosis (t = 0.003). CONCLUSIONS: On the ground of our results of bleeding complication, biliary anastomosis leakage and infectious complication were consequences of pancreatic leakage: failure of a surgical anastomosis has serious consequences, particularly in case of anastomosis of the pancreas to the small bowel, because of the digestive capacities of activated pancreatic secretions.

Minimally invasive esophagectomy: a comparative study of transhiatal laparoscopic approach versus laparoscopic right transthoracic esophagectomy.

BACKGROUND: The development of minimally invasive surgery gave birth to an interest in a mini-invasive approach to esophageal cancer; however, it is still considered to be one of the most complex gastrointestinal surgical operations, and many questions still remain unanswered, regarding the oncologic results of a mini-invasive approach in long-term follow-ups. Here, the authors report on the short-term and long-term results of a series of laparoscopic esophagectomies. PATIENTS AND METHODS: From January 2002 to March 2006, 22 nonrandomized patients were recruited to undergo an esophagectomy for neoplastic disease. The esophagectomy and esophagogastroplasty were carried out using the laparoscopic transhiatal technique in 9 patients; whereas, a combined laparoscopic and right-transthoracic incision was performed in the other 13 patients. RESULTS: The mean follow-up was 21+/-3.23 months (mean+/-SD); range, 2 to 46 months. The overall survival rate resulted 84.0% at 12 months, 61.3% at 24 months, and 51.0% at 36 months. The proportions of cumulative survival showed significant differences when the following variables were considered: site of neoplasm (lower esophagus), American Society of Anesthesiologists 2, chronic obstructive pulmonary disease, type of surgical procedure, and inclusion in neoadjuvant protocol and staging. Recurrence rates were 3 (25%) in the radio-chemotherapy-treated group, and 5 (50%) in the primary surgery group (P=n.s.). CONCLUSIONS: The two-year survival rates (61.3%) recorded in our series are comparable with those reported in other series of both laparoscopic and open surgeries. The logical conclusion was that a less invasive procedure did not imply a less curative one.

Ileocecal Fistula Caused by Multiple Foreign Magnetic Bodies Ingestion.

The incidence of accidental foreign body (FBs) ingestion is 100,000 cases/year in the US, with over than 80% of cases occurring in children below 5 years of age. Although a single FB may pass spontaneously and uneventfully through the digestive tract, the ingestion of multiple magnetics can cause serious morbidity due to proximate attraction through the intestinal wall. Morbidity and mortality depend on a prompt and correct diagnosis which is often difficult and delayed due to the patient's age and because the accidental ingestion may go unnoticed. We report our experience in the treatment of an 11-year-old child who presented to the emergency department with increasing abdominal pain, vomiting, diarrhea, and fever. Surgery evidenced an ileocecal fistula secondary to multiple magnetic FB ingestion with attraction by both sides of the intestinal wall. A 5-centimeter ileal resection was performed, and the cecal fistula was closed with a longitudinal manual suture. The child was discharged at postoperative day 8. After one year, the patient's clinical condition was good.

Liver resection for HCC: analysis of causes and risk factors linked to postoperative complications.

BACKGROUND/AIMS: Hepatic resection is widely accepted as the best treatment for localized hepatocellular carcinoma (HCC), even in those patients affected by cirrhosis after a sharp selection. Notwithstanding technical advances and high experience of liver resection of specialized centers, the rate of complication after surgical resection could be high. Herein we analyzed causes and foreseeable risk factors on the grounds of data derived from a single center surgical population. METHODOLOGY: From September 1989 to March 2005, 134 consecutive patients had liver resection for HCC on cirrhosis at our department. We performed 54 major liver resections and 80 limited resections. RESULTS: In-hospital mortality rate was 7.4%, about 50% of these cases were Child-Pugh B patients. Morbidity rate was 47.7%, caused by the rising of ascites, hepatic insufficiency, biliary fistula, hepatic abscess, hemoperitoneum and pleural effusion. Intraoperative mortality resulted to be influenced by the amount of resected liver volume (p < 0.05), and the rising of complication (p = 0.006). Some technical aspects of surgical procedure are responsible of the rising of complication as: Pringle maneuver length (p = 0.02), the amount of resected liver volume (p = 0.03) and the request of blood transfusion (p = 0.03). CONCLUSIONS: Complications that arise during the postoperative period, although treatable, delay patient's recovery and resumption of liver function; the evaluation of causes and foreseeable risk factors linked to postoperative morbidity during the planning of surgical treatment should play the same role as other factors weighted in the selection of patients eligible for liver resection.

Analysis of survival after pancreatic resection for oncological pathologies.

Surgical treatment of pancreatic cancer is to date the only modality that offers a chance of long-term survival. Potentially curative surgery is an option for only about 15% of patients with pancreatic adenocarcinoma. The aim of this study was to determine the survival and to assess the association of clinical, pathological, and treatment features with survival of patients who underwent resection of pancreatic cancer at the Department of Surgery of Udine University Hospital. From November 1989 to December 2005, 137 consecutive patients, who underwent surgical procedures for pancreatic cancer, were followed in our department. We performed 76 pancreatico-duodenectomy, 26 distal pancreatectomies and 35 total pancreatectomies. The surgical reconstruction after pancreatico-duodenectomy was as follows: 11 closures of the main duct with manual nonabsorbable stitches, 24 closures of the main duct with a linear stapler, 17 occlusions of the main duct with neoprene glue and 24 duct-to-mucosa anastomoses. Mean survival time was 27.7 +/- 26.93 months (mean +/- SD) and mean disease-free survival time was 25.4 +/- 23.06 months (mean +/- SD). 1, 3, 5, 7 and 9-year survival rates were 63.9, 33.7, 21.17, 12.7 and 10.2%, respectively. Significant differences in survival were recorded by the Log-rank test for age > 70 (p = 0.001), surgical procedures (p = 0.00046) and presence of metastases (p = 0.0055) The treatment of pancreatic cancer is undertaken with two different aims. The first is radical surgery for patients with early-stage disease, mainly stage I and partly stage II. In all other cases, the aim of treatment is the palliation of the several distressing symptoms related to this cancer. The standard treatment option for resectable tumours is radical pancreatic resection according to the Whipple procedure or total pancreatectomy.

Evolution of incidental branch-duct intraductal papillary mucinous neoplasms of the pancreas: A study with magnetic resonance imaging cholangiopancreatography.

AIM: To investigate the type and timing of evolution of incidentally found branch-duct intraductal papillary mucinous neoplasms (bd-IPMN) of the pancreas addressed to magnetic resonance imaging cholangiopancreatography (MRCP) follow-up. METHODS: We retrospectively evaluated 72 patients who underwent, over the period 2006-2016, a total of 318 MRCPs (mean 4.4) to follow-up incidental, presumed bd-IPMN without signs of malignancy, found or confirmed at a baseline MRCP examination. Median follow-up time was 48.5 mo (range 13-95 mo). MRCPs were acquired on 1.5T and/or 3.0T systems using 2D and/or 3D technique. Image analysis assessed the rates of occurrence over the follow-up of the following outcomes: (1) imaging evolution, defined as any change in cysts number and/or size and/or appearance; and (2) alert findings, defined as worrisome features and/or high risk stigmata (e.g., thick septa, parietal thickening, mural nodules and involvement of the main pancreatic duct). Time to outcomes was described with the Kaplan-Meir approach. Cox regression model was used to investigate clinical or initial MRCP findings predicting cysts changes. RESULTS: We found a total of 343 cysts (per-patient mean 5.1) with average size of 8.5 mm (range 5-25 mm). Imaging evolution was observed in 32/72 patients (44.4%; 95%CI: 32-9-56.6), involving 47/343 cysts (13.7%). There was a main trend towards small (< 10 mm) increase and/or decrease of cysts size at a median time of 22.5 mo. Alert findings developed in 6/72 patients (8.3%; 95%CI: 3.4-17.9) over a wide interval of time (13-63 mo). No malignancy was found on endoscopic ultrasound with fine-needle aspiration (5/6 cases) or surgery (1/6 cases). No clinical or initial MRCP features were significantly associated with changes in bd-IPMN appearance (P > 0.01). CONCLUSION: Changes in MRCP appearance of incidental bd-IPNM were frequent over the follow-up (44.4%), with relatively rare (8.3%) occurrence of non-malignant alert findings that prompted further diagnostic steps. Changes occurred at a wide interval of time and were unpredictable, suggesting that imaging follow-up should be not discontinued, though MRCPs might be considerably delayed without a significant risk of missing malignancy.

Macrocystic serous cystadenoma of the pancreas: Report of 4 cases.

BACKGROUND: Macrocystic serous cystadenomas (MaSCA) are rare benign tumor of the pancreas which represent an atypical macroscopic morphologic variant of serous cystadenomas (SCA). They are characterized by a limited number of cysts with a diameter of >2 cm and share imaging features overlapping those of mucinous cystic neoplasm (MCN) and branch-duct intraductal papillary mucinous neoplasm (BD-IPMN), thus frequently making the pre-operative radiologic diagnosis difficult. MATERIALS AND METHODS: Four cases of MaSCA, which were surgically treated in our structure, are reported. RESULTS: Two women (62 and 39 year-old) presented with upper abdominal pain and palpable mass underwent CT with evidence of a lobulated cystic neoformation (98 × 70 and 94 × 75 mm respectively) originating from the body and the tail of the pancreas respectively. They underwent distal pancreatectomy for suspected MCN. A 38 year-old woman underwent laparoscopic distal pancreatectomy because of the incidental finding of an unilocular cystic lesion in the pancreatic tail (23 mm) of indeterminate origin (MCN, SCA or metastasis). In a 40 year-old woman, admitted for acalculous acute pancreatitis, an unilocular cystic lesion in the body of the pancreas (62 mm) was detected and confirmed after 2 months at CT, therefore she underwent distal pancreatectomy for suspected pseudocyst or SCA. In all of the 4 patients the histological examination of the specimens revealed a MaSCA. CONCLUSION: Imaging techniques have a low diagnostic power in terms of differentiation of MaSCA from malignant lesions (as MCNs and BD-IPMN). In the clinical practise of MaSCA, surgery appears to gain indications that are wider than those correlated to the pathologic outcome, because of the necessity of a correct differential diagnosis from potentially malignant cystic tumors and the frequent symptoms requiring treatment.

Schwannoma of the sympathetic cervical chain presenting as a lateral cervical mass.

We discuss about the diagnosis and treatment of Schwannoma arising from the sympathetic cervical chain on the basis of a case report on a patient whose previously diagnosis was paraganglioma.

Postoperative complications linked to pancreaticoduodenectomy. An analysis of pancreatic stump management.

AIMS: To analyze the role of different procedures in the management of pancreatic stump according to the incidence of postoperative morbidity derived from the data of a single center surgical population. METHODS: From 1989 to 2005 we performed 76 pancreaticoduodenectomies (PD) and 26 distal pancreatectomies (DP). The surgical reconstruction after PD was as follows: 11 manual non-absorbable stitches closure of the main duct, 24 closures of the main duct with linear stapler, 17 occlusions of the main duct with neoprene glue and 24 duct-to-mucosa anastomosis. RESULTS: In the PD group, the morbidity rate was 60%, caused by: pancreatic leakage in 48% of patients, hemorrhagic complications in 10% following surgical procedure and infectious complications in 15%. After DP we recorded: leakage in 3.9%, haemoperitoneum in 15.4% and no complications in 80.7%. The multivariate analysis showed that the in-hospital mortality was linked to the surgical procedure (PD, p=0.003) and to the following complications: pancreatic leakage (p=0.004), haemoperitoneum (p=0.00045) and infectious complications (p=0.0077). Bleeding complications, biliary anastomosis leakage and infectious complications were consequences of pancreatic leakage (p=0.025, p=0.025 and p=0.025 respectively). CONCLUSION: Manual non-absorbable stitch closure of the main duct and occlusion of the main duct with neoprene glue should be avoided in the reconstructive phase.
