RESUMO
UNLABELLED: Body packing is a way to deliver packages of drugs hidden in body cavities. In Europe, as noted the latest report coming from the Brussels observatory, there are 74 million drugs consumers. Italy is in pole position and Perugia was considered as a "capital city" in the drug market. Body packers usually swallow the drug packets, although their insertion into the rectum and vagina has also been reported. The management depends on whether or not the patient becomes symptomatic. Surgery is indicated in presence of repeated bouts of drug toxicity not controlled by medical treatment, radiological evidence of packet retention in the stomach, intestinal obstruction or perforation. It is also important to emphasize that, in a multidisciplinary context, the patient's management before reaching the operating theater if symptomatic, is aimed to stabilization and is usually demanded to Intensive Care Unit (ICU) physicians. We present our center recent experience with body packers, managed both with surgical and conservative treatments. KEY WORDS: Body packers, Drugs, Emergency surgery, Foreign bodies.

INTRODUCTION: The most frequent reason for performing a distal pancreatectomy is the presence of cystic or neuroendocrine tumors, in which the distal pancreatic stump is often soft and non fibrotic. This parenchymal consistence represents the main risk factor for post-operative pancreatic fistula. In order to identify the fistula and assessing its severity postoperative monitoring of amylase from intraperitoneal drains is important. METHODS: From a retrospective multicentric database analysis were included 33 patients who underwent distal pancreatectomy for pancreatic neoplastic disease. RESULTS: Postoperative pancreatic fistula occurred in four cases. One patient had a ductal adenocarcinoma, two presented with pancreatic endocrine neoplasms and the last one had an intraductal papillary mucinous neoplasia. Two patients underwent open, the other two laparoscopic distal pancreatectomy. DISCUSSION: Postoperative pancreatic fistulas after distal pancreatectomy worsen the quality of life, prolong the post-operative stay and delay further adjuvant therapy. In patients who underwent distal pancreatectomy literature exposed some advantages deriving from the placement of abdominal drainages only in selected cases and from their early removal. Patients presenting a high risk of pancreatic fistula had higher amylase levels of drainage fluid in the first postoperative day. CONCLUSION: POPF is the most frequently complication after pancreatectomy. In our analysis DFA1>5000 can be considered as a predictive factor for pancreatic fistula. For this reason, the systematic measurement of amylase in drain fluid in first-postoperative day can be considered a good clinical practice.

INTRODUCTION: Spleen-preserving left pancreatectomy (SPDP) with splenic vessels preservation (SVP) or without (Warshaw technique, WT) has been described with robotic, laparoscopy and open surgery. Nevertheless, significant data on medium- and long-term follow-up are still not available, since data in literature are scarce and the level of evidence is low. METHODS: In this retrospective study, we describe and compare short and medium term results of spleen-preserving distal pancreatectomy in eight patients. RESULTS: In WT group the duration and the intraoperative bleeding was superior than SVP group. The incidence of perigastric collateral vessels and presence of submucosal varices evidenced at CT scan was 66% in WT group, while only one case occurred in SVP group. DISCUSSION: The limit of laparoscopic approach is the fact that it needs advanced laparoscopic skills, which might result in intraoperative bleeding and splenectomy. The most of literature considered salvage WT intraoperatively performed in case of classical SVP and not only elective WT. The consequence is that there is no difference in immediate postoperative results (operative time, intraoperative bleeding, hospital stay) that are in favour of SVP because WT is performed only in case of failure in preserving the splenic vessels. In fact when this intervention is performed electively, the procedure time is reduced as well as the intraoperative bleeding. CONCLUSIONS: WT is safe and feasible, even if there are not definitive evidences that demonstrate it is superior to classic SVP. RCTs are needed to determine advantages and disadvantages of WT compared to the classic SVP.

Autoimmune pancreatitis (AIP) is an insidious disease of non-specific symptomatology. To make correct diagnosis three different findings must correlate: radiological imaging, serological markers, and histology. This is not easy, and furthermore an incorrect diagnosis can lead to incorrect management and even patient death. We present our experience with a case of AIP in a young woman (34 years old) affected by different autoimmune pathologies with a history of abdominal pain. The diagnosis was made correlating histological findings and anamnestic data, although there were no radiological or serological findings. However, the management of this case was complicated by acute pancreatitis. In our case, we had only a histological sample and anamnestic data. So in these cases of positive history for autoimmune disorders and unclear clinical signs, AIP should be considered in differential diagnosis.
RESUMO
Insulinoma is a rare pancreatic endocrine tumor, typically sporadic and solitary. Although the Whipple triad, consisting of hypoglycemia, neuroglycopenic symptoms, and symptoms relief with glucose administration, is often present, the diagnosis may be challenging when symptoms are less typical. We report a case of road accident due to an episode of loss of consciousness in a patient with pancreatic insulinoma. In the previous months, the patient had occasionally reported nonspecific symptoms. During hospitalization, endocrine examinations were compatible with an insulin-producing tumor. Abdominal computerized tomography and magnetic resonance imaging allowed us to identify and localize the tumor. The patient underwent a robotic distal pancreatectomy with partial omentectomy and splenectomy. Insulin-producing tumors may go undetected for a long period due to nonspecific clinical symptoms, and may cause episodes of loss of consciousness with potentially lethal consequences. Robot-assisted procedures can be performed with the same techniques of the traditional surgery, reducing surgical trauma, intraoperative blood loss, and hospital stays.

AIM: Robotic systems are getting widely spread in recent years given the different technical advantages over traditional laparoscopy. Rectal surgery seems to benefit from this approach, for its ability to easily work in a confined space such as the pelvic cavity. The objective is to present results obtained by the robotic approach in patients with rectal cancer and to give technical considerations. METHOD: Data were prospectively collected in order to evaluate surgical and oncological outcomes. Subjects underwent robotic rectal resection in the period between June 2011 and June 2014 at the Department of Digestive Surgery, "S. Maria" Hospital - Terni (Italy). MAIN OUTCOME MEASURES: Patient characteristics and tumor, overall operative time, conversion to open surgery, site of mini-laparotomy for specimen extraction, intraoperative blood loss, intraoperative complications, time to first bowel movement, time-to-liquid and solid intake, postoperative complications, mortality, hospital stay, thirty-day complications, histopathological examination. RESULTS: 40 consecutive patients underwent robotic resection of the rectum. Median operative time was 340 min (235-460 min), no procedure was converted. Median hospital stay was 5 days (3-18 days). Mesorectum resection was complete in all patients. Median number of harvested lymph nodes was 19 (6-35), median distal resection margin was 4 cm (2-8 cm). CONCLUSION: Robotic rectal surgery is safe and feasible in particular by facilitating the surgeon during the delicate phases of tissue dissection.

AIM: To describe three cases of solitary cecal diverticulum, and trying to evaluate the better method of diagnosis and treatment with analysis of the literature. MATERIAL OF STUDY: Description of three cases of solitary cecal diverticulum's perforation admitted in the Department of General and Oncologic Surgery, Santa Maria della Misericordia Hospital, Perugia, during the period January 2011 - January 2012. RESULTS: In all patients the clinical presentation was very similar to that of acute appendicitis. Preoperative diagnosis was achieved in one case through abdominal CT scan, other two cases were identified at final pathology. At one year from the treatment all patient are still alive. DISCUSSION: Cecal diverticulum is a rare condition, often diagnosed either casually or because of inflammatory or perforative complications. The highest incidence is found in Western population. Because of the clinical presentation, very similar to the appendicitis, and the inflammatory reaction involving the colon and its surrounding tissues, the pre- and intra-operative diagnosis are very difficult. The diagnosis is almost always histological. The treatment may vary from simple expectant medical management, carried out with bowel rest, parenteral support and antibiotics as for left-sided diverticulitis, to surgical approach, performed through simple diverticulectomy or by classical right hemicolectomy. CONCLUSION: Pre-surgical and, also intra-operative, diagnosis of perforated solitary cecal diverticulum is clearly difficult. CT scan represents the gold standard for the differential diagnosis. Right hemicolectomy is an effective and safe approach, allowing accurate control, preventing complications and recurrences, and it represents the optimal management of the disease.

Despite centuries of anatomical studies, controversies and contradictions still exist in the literature regarding the definition, anatomical terminology and the limits of the abdominal wall. We conducted a systematic research of books published from 1901 until December 2012 in Google Books. After the index screening, 16 remaining books were further assessed for eligibility. We decided to exclude journals. The aim of the study was to focus on surface landmarks and borders of the abdominal cavity. After this revision of the literature, we propose that the surface landmarks of the abdominal wall should be standardized.
RESUMO
BACKGROUND: Laparoscopic left colectomy has obtained a large spread in colon surgery for malignant disease despite the need for an adequate learning curve. However few studies reported long term data in comparison with open left colectomy and most of the authors of large series on colorectal surgery don't describe, in subgroup analysis, results obtained in left colonic resections. The aim of this study is to report the short and long term follow-up of laparoscopic left colon resection in comparison with the open approach, from a single centre, performed in the same timeframe. METHODS: Between January 2005 to January 2007, 55 patients with sigma adenocarcinoma underwent to laparoscopic or open left colectomy at the Department of Digestive Surgery, "S. Maria" hospital in Terni - Italy. Perioperative and histopathological data and results from oncological follow-up, until April 2013, are analyzed. RESULTS: 28 patients underwent laparoscopic left colectomy, while 27 patients open left colectomy. Mean hospital stay was 8.44 ± 1.21 in the laparoscopic group versus 6.86 ± 1.01 in the open group. The histopathological analysis shows a mean of 18.13 ± 6.8 lymph nodes removed after laparoscopy and 13.96 ± 5.72 after open surgery (P = 0.02). Kaplan-Meier analysis does not reveal significative differences in disease free survival (HR = 0.85; 95% CI = 0.21-3.40; P = 0.81). Overall survival up to 5 years shows one death per group. CONCLUSIONS: Laparoscopy, respect to the open approach, could improve perioperative clinical outcomes, hospital stay and harvested lymph nodes with comparable long term oncological follow-up in patients with sigmoid colon cancer.

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract and is caused by incomplete obliteration of the vitelline duct during intrauterine life. MD affects less than 2% of the population. In most cases, MD is asymptomatic and the estimated average complication risk of MD carriers, which is inversely proportional to age, ranges between 2% and 4%. The most common MD-related complications are gastrointestinal bleeding, intestinal obstruction and acute phlogosis. Excision is mandatory in the case of symptomatic diverticula regardless of age, while surgical treatment for asymptomatic diverticula remains controversial. According to the majority of studies, the incidental finding of MD in children is an indication for surgical resection, while the management of adults is not yet unanimous. In this case report, we describe the prophylactic resection of an incidentally detected MD, which led to the removal of an occult mucosal carcinoid tumor. In literature, the association of MD and carcinoid tumor is reported as a rare finding. Even though the strategy for adult patients of an incidental finding of MD during surgery performed for other reasons divides the experts, we recommend prophylactic excision in order to avoid any further risk.

Perforation of descending colon cancer combined with iliopsoas abscess and fistula formation is a rare condition and has been reported few times. A 67-year-old man came to our first aid for an acute pain in the left iliac fossa, in the flank, and in the ipsilateral thigh. Ultrasonography and computed tomography revealed a left abdominal wall, retroperitoneal, and iliopsoas abscess that also involved the ipsilateral obturator muscle. It proceeded with an exploratory laparotomy that showed a tumor of the descending colon adhered and perforated in the retroperitoneum with abscess of the iliopsoas muscle on the left-hand side, with presence of a fistula and liver metastases. A left hemicolectomy with drainage of the broad abscess was performed. Pathologic report findings determined adenocarcinoma of the resected colon.
RESUMO
BACKGROUND: The spleen is the most easily injured organ in abdominal trauma. The conservative, operative approach has been challenged by several reports of successful non-operative management aided by the power of modern diagnostic imaging. The aim of our retrospective study was to compare non-operative management with surgery for cases of splenic injury. METHODS: We compared seven patients who were treated with non-operative management (NOM) between 2007 and 2011 to six patients with similar pre-operative characteristics who underwent operative management (OM). RESULTS: The average hospital stay was lower in the NOM group than in the OM group, although the difference was not statistically significant. The NOM group required significantly fewer transfusions, and no patients in the NOM group required admission to the intensive care unit. In contrast 83% of patients in the OM group were admitted to the intensive care unity. The failure rate of NOM was 14.3% in our experience. CONCLUSION: In our experience, NOM is the treatment of choice for grade I, II and III blunt splenic injuries. NOM is slightly less than surgery, but this is an unadjusted comparison and the 95% confidence interval is extremely wide - from 0.04 to 16.99. Splenectomy was the chosen technique in patients who met exclusion criteria for NOM, as well as for patients with grade IV and V injury.

INTRODUCTION: Pancreatic or duodenal invasion by locally advanced right colon cancer is an unusual event whose management still represents a surgical challenge. This review aims to compare results of limited vs. extended resection in case of primary right colon cancer invading pancreas and/or duodenum. METHODS: A systematic search in Medline, Embase and Cochrane Central Register of Controlled Trials (CENTRAL) was performed. All trials describing the surgical treatment of right colon cancer invading pancreas and/or duodenum were considered. A data extraction sheet was developed, based on the Cochrane Consumers and Communication Review Group's data extraction template. RESULTS: 5-years overall survival was 52% after en bloc pancreaticoduodenectomy plus right hemicolectomy vs. 0 and 25% in case of duodenal resection with correction by direct suture or pedicled ileal flap, respectively. 30-day postoperative morbidity rate was slightly higher after en block resections (12.8%) with respect to duodenal local resection and direct suture or pedicled ileal flap repair (0 and 12.2%, respectively). After extended resection the rate of pancreatico-jejunal anastomotic leakage was 7.7%. CONCLUSIONS: In patients with right colon cancer extended to the pancreas and/or duodenum surgical multivisceral resection is suggested when complete tumour removal (R0) is achievable. Even though no significant differences in postoperative morbidity and mortality have been shown, 5 y OS has improved in extended resections as compared to duodenal local resection with defect repair either by direct suture or by a pedicled ileal flap.

Each year, ~988,000 new cases of stomach cancer are reported worldwide. Uniformity for the definition of advanced gastric cancer (AGC) is required to ensure the improved management of patients. Various classifications do actually exist for gastric cancer, but the classification determined by lesion depth is extremely important, as it has been shown to correlate with patient prognosis; for example, early gastric cancer (EGC) has a favourable prognosis when compared with AGC. In the literature, the definition of EGC is clear, however, there is heterogeneity in the definition of AGC. In the current study, all parameters of the TNM classification for AGC reported in each previous study were individually analysed. It was necessary to perform a comprehensive systematic literature search of all previous studies that have reported a definition of ACG to guarantee homogeneity in the assessment of surgical outcome. It must be understood that the term 'advanced gastric cancer' may implicate a number of stages of disease, and studies must highlight the exact clinical TNM stages used for evaluation of the study.
RESUMO
Currently melanoma has the fastest growing incidence of all cancers in men and the second in women (after lung cancer) in Western countries. Since prognosis of skin melanoma is excellent in early stages but dramatically worsens in advanced stages, an early diagnosis is fundamental in granting patients a favorable outcome. Sentinel node (SN) biopsy represents the gold standard for accurately staging melanoma, but other tests are commonly endorsed both in the initial staging work-up and in the follow-up, such as ultrasonography, computed tomography (CT)-scan and positron emission tomography (PET)-CT. PET-CT, among others, has high sensitivity and specificity for the study of distant metastases, the assessment of soft tissues and lymph node involvement, and for the guidance of surgical biopsies. Ultrasonography (US) is a non-invasive procedure whose use has recently expanded in our service, both preoperatively, intraoperatively and postoperatively, thanks to its wide availability, low costs and easy and fast reproducibility; ultrasonography even surpassed the reliability of PET-CT or CT-scan in the seven cases presented herein. US is operator-dependent, and this is probably the major limitation of the procedure, together with lack of prospective studies validating its strength, but our preliminary study demonstrates that ultrasound can assume an important role in melanoma, both for staging and the follow-up of patients, especially with lymph nodal or subcutaneous involvement.

BACKGROUND: Bariatric surgery is an effective treatment to obtain weight loss in severely obese patients. The feasibility and safety of bariatric robotic surgery is the topic of this review. METHODS: A search was performed on PubMed, Cochrane Central Register of Controlled Trials, BioMed Central, and Web of Science. RESULTS: Twenty-two studies were included. Anastomotic leak rate was 8.51% in biliopancreatic diversion. 30-day reoperation rate was 1.14% in Roux-en-Y gastric bypass and 1.16% in sleeve gastrectomy. Major complication rate in Roux-en-Y gastric bypass resulted higher than in sleeve gastrectomy ( 4,26% vs. 1,2%). The mean hospital stay was longer in Roux-en-Y gastric bypass (range 2.6-7.4 days). CONCLUSIONS: The major limitation of our analysis is due to the small number and the low quality of the studies, the small sample size, heterogeneity of the enrolled patients and the lack of data from metabolic and bariatric outcomes. Despite the use of the robot, the majority of these cases are completed with stapled anastomosis. The assumption that robotic surgery is superior in complex cases is not supported by the available present evidence. The major strength of the robotic surgery is strongly facilitating some of the surgical steps (gastro-jejunostomy and jejunojejunostomy anastomosis in the robotic Roux-en-Y gastric bypass or the vertical gastric resection in the robotic sleeve gastrectomy).

BACKGROUND: The evidence regarding the effectiveness and safety of laparoscopic sleeve gastrectomy (LSG) has been mostly based on the data derived from nonrandomized studies. The objective of this study was to evaluate the outcomes of LSG and to present an up-to-date review of the available evidence based on the recent publications of new randomized, controlled trials (RCTs). METHODS: PubMed, Embase, and Cochrane Central Register of Controlled Trials were searched until November 2012 for RCTs on LSG. RESULTS: Fifteen RCTs, comprising a total of 1191 patients, of whom 795 had undergone LSG, were included. No patient required conversion to open surgery for LSG, laparoscopic gastric bypass (LGB), or laparoscopic adjustable gastric banding (LAGB) procedures. There were no deaths, and the complication rate was 12.1% (range 10%-13.2%) in the LSG group versus 20.9% (range 10%-26.4%) in the LGB group, and 0% in the LAGB group (only 1 RCT). The complications included leakage, bleeding, stricture, and reoperation that occurred with rates of .9%, 3.3%, 0%, and 2.1%, respectively, in the LSG group and rates of 0%, 5%, 0%, and 4%, respectively, in the LGB group. The average operating time in the LSG group was 106.5 minutes versus 132.3 minutes in the LGB group. The percentage of excess weight loss (%EWL) ranged from 49% to 81% in the LSG group, from 62.1% to 94.4% in the LGB group, and from 28.7% to 48% in the LAGB group, with a follow-up ranging from 6 months to 3 years. The type 2 diabetes mellitus (T2DM) remission rate ranged from 26.5% to 75% in the LSG group and from 42% to 93% in the LGB group. CONCLUSIONS: LSG is a well-tolerated, feasible procedure with a relatively short operating time. Its effectiveness in terms of weight loss is confirmed for short-term follow-up (≤ 3 years). The role of LSG in the treatment of T2DM requires further investigation.

INTRODUCTION: The goal of non-operative management (NOM) for blunt splenic trauma (BST) is to preserve the spleen. The advantages of NOM for minor splenic trauma have been extensively reported, whereas its value for the more severe splenic injuries is still debated. The aim of this systematic review was to evaluate the available published evidence on NOM in patients with splenic trauma and to compare it with the operative management (OM) in terms of mortality, morbidity and duration of hospital stay. METHODS: For this systematic review we followed the "Preferred Reporting Items for Systematic Reviews and Meta-analyses" statement. A systematic search was performed on PubMed for studies published from January 2000 to December 2011, without language restrictions, which compared NOM vs. OM for splenic trauma injuries and which at least 10 patients with BST. RESULTS: We identified 21 non randomized studies: 1 Clinical Controlled Trial and 20 retrospective cohort studies analyzing a total of 16,940 patients with BST. NOM represents the gold standard treatment for minor splenic trauma and is associated with decreased mortality in severe splenic trauma (4.78% vs. 13.5% in NOM and OM, respectively), according to the literature. Of note, in BST treated operatively, concurrent injuries accounted for the higher mortality. In addition, it was not possible to determine post-treatment morbidity in major splenic trauma. The definition of hemodynamic stability varied greatly in the literature depending on the surgeon and the trauma team, representing a further bias. Moreover, data on the remaining analyzed outcomes (hospital stay, number of blood transfusions, abdominal abscesses, overwhelming post-splenectomy infection) were not reported in all included studies or were not comparable, precluding the possibility to perform a meaningful cumulative analysis and comparison. CONCLUSIONS: NOM of BST, preserving the spleen, is the treatment of choice for the American Association for the Surgery of Trauma grades I and II. Conclusions are more difficult to outline for higher grades of splenic injury, because of the substantial heterogeneity of expertise among different hospitals, and potentially inappropriate comparison groups.
