ABSTRACT

OBJECTIVE: To describe the spectrum of being detected gene mutations in patients with epilepsy in clinical practice of neurologists specializing in epilepsy with an analysis of diagnosed epileptic syndromes, the characteristics of seizures, the timing of a genetic diagnosis, options and treatment effectiveness. PATIENTS AND METHODS: The study included 100 patients (40 boys, 60 girls) with epilepsy and/or epileptic encephalopathy and a gene mutation identified. The average age was 6.9±5.1 years. Through remote access, epilepsy specialists filled out a specially designed unified table containing information from outpatient case history. RESULTS AND DISCUSSION: There are patients with a wide range of gene mutations, the leading of which is a mutation in the SCN1A gene (15%). The main method (85%) of detection remains the sequencing of the last generation in the «Hereditary Epilepsy¼ panel. Years pass from the onset of the disease to the genetic diagnosis (Me - 3 years). In most cases, patients with severe (52% have epileptic encephalopathy, 88% have developmental disorders) and pharmacoresistant (mean amount of anti-epileptic drugs - 3.8±2.2, multitherapy - 70%) syndromes have undergone genetic testing. In the treatment of these patients epileptologists are increasingly (52%) use alternative methods: steroids, ketogenic diet and others. The absence of seizures was observed only in 46% of patients. CONCLUSION: Thus, in the outpatient practice of epileptologists, patients with a wide range of gene mutations are found. As a rule, these are patients with severe, therapy-resistant epileptic syndromes.

ABSTRACT

BACKGROUND: One critical step in the therapy of patients with localized pancreatic cancer is the determination of local resectability. The decision between primary surgery versus upfront local or systemic cancer therapy seems especially to differ between pancreatic cancer centers. In our cohort study, we analyzed the independent judgement of resectability of five experienced high volume pancreatic surgeons in 200 consecutive patients with borderline resectable or locally advanced pancreatic cancer. METHODS: Pretherapeutic CT or MRI scans of 200 consecutive patients with borderline resectable or locally advanced pancreatic cancer were evaluated by 5 independent pancreatic surgeons. Resectability and the degree of abutment of the tumor to the venous and arterial structures adjacent to the pancreas were reported. Interrater reliability and dispersion indices were compared. RESULTS: One hundred ninety-four CT scans and 6 MRI scans were evaluated and all parameters were evaluated by all surgeons in 133 (66.5%) cases. Low agreement was observed for tumor infiltration of venous structures (κ = 0.265 and κ = 0.285) while good agreement was achieved for the abutment of the tumor to arterial structures (interrater reliability celiac trunk κ = 0.708 P < 0.001). In patients with vascular tumor contact indicating locally advanced disease, surgeons highly agreed on unresectability, but in patients with vascular tumor abutment consistent with borderline resectable disease, the judgement of resectability was less uniform (dispersion index locally advanced vs. borderline resectable p < 0.05). CONCLUSION: Excellent agreement between surgeons exists in determining the presence of arterial abutment and locally advanced pancreatic cancer. The determination of resectability in borderline resectable patients is influenced by additional subjective factors.

ABSTRACT

BACKGROUND: Pancreatic anastomosis is the Achilles heel of pancreatic surgery. Despite substantial progress in surgical techniques the rate of postoperative pancreatic fistulas remains very high. For this reason various supportive measures to secure pancreatic anastomoses are of continuing interest. OBJECTIVE: This review presents the newest evidence-based data on supportive measures designed to secure a pancreatic anastomosis. MATERIAL AND METHODS: The most recent meta-analyses, randomized controlled trials and the largest retrospective studies on the role of pancreatic duct stenting, double loop reconstruction, autologous patches and drainage in pancreaticoduodenectomy were taken into account. The value of somatostatin analogues, perioperative nutrition and fluid management is critically discussed. RESULTS: The existing body of evidence on supportive measures is insufficient and remains controversial. The use of somatostatin analogues, drainages and restrictive perioperative fluid management has proven effective. In contrast, routine stenting of the pancreatic duct cannot be recommended. Other approaches, such as double loop reconstruction and use of autologous patches lack sufficient evidence. CONCLUSION: Meticulous surgical technique and surgeon experience remain the cornerstones of performing a safe pancreatic anastomosis; however, some additional supportive measures seem to have significant potential and should be further investigated in large and well-designed prospective clinical trials.

ABSTRACT

Many patients with epilepsy receive treatment in polytherapy. Selection of antiepileptic drugs (AEDs) for the combination should be carried out in accordance with the principles of rational polytherapy, taking into account the mechanism of action, pharmacokinetic (PK) and pharmacodynamic (PD) properties of drugs. Along with levetiracetam, gabapentin, vigabatrin and pregabalin, lacosamide (LCM) shows superior PK profile in rating of all AED and can be combined with any of them. The goal of this study was to evaluate efficacy and tolerability of LCM in patients with uncontrolled partial onset seizures (POS) in routine clinical practice. METHODS: 181 patient's charts from 14 sites in Russia have been analyzed in retrospective manner. Patients 16 years old and older with POS with or without secondary generalization were included. Documented observation period of up to 12 months after initiation or until discontinuation of LCM therapy. Primary effectiveness variables was retention at Observational Point 3 (approximately 12 months). Other variables were: percentage change from historical baseline in seizure frequency, 50% and 75% treatment response and seizure-free status at the Observational Points 1, 2 and 3 (approximately 3, 6 and 12 months) and incidence and reason of treatment discontinuation. RESULTS: retention rate was high with 89.5% after 12-month observation. The development of seizure frequency showed a continuous decrease in terms of 50%, 75% treatment respond rates and seizure free status. A total of 5 adverse drug reactions leading to discontinuation of LCM therapy were recorded in 5 of 181 patients (2.8%) during the observation period. The high retention rate observed in this retrospective chart review is assumed to indicate a good tolerability and effectiveness of an adjunctive LCM treatment in patients with uncontrolled partial epilepsy in Russia.

ABSTRACT

Background: Postoperative pancreatic fistulas (POPF) remain a major concern after distal pancreatectomy. Irrespective of the technique to close the pancreatic remnant, pancreatic fistulas will occur in approximately 30 % of patients undergoing distal pancreatectomy. For the first time ever, autologous fibrin sealant (Vivostat®) was used to additionally seal the pancreatic remnant after a distal pancreatectomy. The aim was to analyse whether this changes the postoperative outcome. Patients/Material and Methods: In 2015, a technical case series was performed in 15 patients who underwent distal pancreatectomy. The pancreatic remnant was additionally sealed with autologous fibrin sealant (Vivostat®). Results: A postoperative pancreatic fistula (POPF) occurred in 5/15 patients (33 %). One patient had a POPF grade A (1/15, 6.7 %), whereas a POPF grade B occurred in 4/15 patients (26.7 %). 75 % (3/4) of the patients with a POPF grade B were sufficiently treated with antibiotics, whereas a CT-guided percutaneous drainage had to be placed only in one case. Conclusion: Autologous fibrin sealant is simple to apply and seems to be well tolerated. However, it does not seem to avoid the development of postoperative pancreatic fistulas after distal pancreatectomy.

ABSTRACT

OBJECTIVE: to investigate the Cyclin D1+ cells levels changes, associated CCND1 and PNKP genes in peripheral blood mononuclear cells in clean up workers of Chornobyl accident with different state of immune system in depends on the dose irradiation. MATERIAL AND METHODS: Relative level of Cyclin D1+cells in peripheral blood mononuclears of 39 clean up workers, men, irradiated in dose range (0,01-2,00) Gy have been analyzed. Immunological status of examinee' subjects was determined by CD3/19, CD4/8, CD3/HLA DR, СD3/16/56 testing using flow cytometry method and Ig A,M,G testing by immunoenzymatic assay in blood. CCND1 та PNKP gene expression, which associated with Cyclin D1 metabolism, was conducted using PCR real time method. The obtained results were compared in relation to data from 18 healthy men, who had no contact with ionizing radiation over then nature background. RESULTS: Аnalyzed data of the nuclear controller of cell cycle - Cyclin D1 protein expression changes and related CCND1 та PNKP genes in peripheral blood mononuclear cells in clean up workers Chornobyl accident with different status of immune system in remote period after exposure is represented. It is shown, that in examinees' subjects exposed in dose > 0,1 Gy percentage of Суclin D1+ cells is elevated against normal range and correlates with dose of radiation (rs = 0,417, p = 0,048). Normal range deflation of relative amount of Cyclin D1+cells connects with changes in cellular and humoral immunity. Decline of relative amount of Cyclin D1+ cells below the control level following CD3+ lymphocytes decrease and CD3 16+56+ elevation in clean up workers exposed in dose < 0,35 Gy. Increase of relative amount of Cyclin D1+ cells above the control range associates with CD3+ fall together with tendency of CD3+16+56+ lymphocytes fall that attends the IgG elevation in examinees' subjects with dose > 0,35 Gy. Percentage of Cyclin D1+ cells correlates with CD3 16+56+ (rs = 0,872, p = 0,049), CD8+ and IgG (rs = 0,683, p = 0,042; rs = 0,809, p = 0,014), CD4+ (rs = 0,602, p = 0,029), CD19+ and IgM (rs = 0,604, p = 0,017; rs = 0,538, p = 0,038) under condition of increased level CD4+, CD19+, Іreg. and IgG accordantly. Reviled decrease the CCND1 and PNKP gene expression in clean up workers exposed in dose > 0,1 Gy following appearance of correlation between (relative quantification) RQ PNKP and irradiation dose (rs = 0,638, p = 0,035) and also with RQ PNKP and percentage of Cyclin D1+ cells (rs = 0,792, p = 0,034).Concusions. Reveled changes in expression of Cyclin D1+ cells and regulation of related genes may point on possi ble radiation associated firm molecular disturbances occurred during elimination of consequences of Chornobyl accident, that could be a potential basis for cell and humoral communicative links breach in immune system result ing in elevation of stochastic effects like oncopathology in clean up workers of Chornobyl accident in remote peri od after exposure.

ABSTRACT

BACKGROUND: For surgeons the early identification of patients with clostridium difficile infections (CDI) is important, because the incidence and virulence of this potentially life-threatening disease are increasing. OBJECTIVES: The aim of this study was to describe the frequency of CDI among surgical patients, to analyze which treatment was successful and to define which factors were associated with mortality. METHODS: A retrospective analysis of patients with CDI was performed. RESULTS: From January 2004 to June 2012 the overall incidence of CDI among all departments at the St. Josef Hospital, Ruhr University Bochum was 0.6 % (1669 out of 301,919 patients). In 2004 the number of surgical patients with CDI was 1 which increased to 41 in 2011. Before the diagnosis of CDI was made 84 % (151 out of 179) of patients had received an antibiotic treatment. Conservative management of CDI was performed with metronidazole in 75 % (134 out of 179), 60 % (107 out of 179) received vancomycin, while 44 % (79 out of 179) received a combination of metronidazole and vancomycin, tygecycline or fidaxomidin. The overall mortality was 7 % (12 out of 179). There was a significant association with mortality for patients with sepsis, readmission to the intensive care unit (ICU), requirement for vasopressor therapy and intubation with mechanical ventilation. In 4 % of patients (7 out of 179) colectomy was carried out. Despite maximum intensive care management, 86 % (6 out of 7) of patients who underwent colectomy ultimately died. CONCLUSION: Although conservative management is successful for most patients with CDI, the mortality is high for patients who require intensive care management secondary to CDI. Mortality after colectomy for CDI is almost 100 %, mostly because the operation is usually only performed as a last resort in patients with sepsis. The most important risk factor for CDI is a prior antibiotic therapy.

ABSTRACT

Objective. To compare the effect of radiation dose and time after exposure on formation of γ-H2AX histone in Chornobyl clean-up workers and personnel who perform work activities at the zone of high radiation risks. Materials and Methods. The expression of γ-H2AX histone in peripheral blood lymphocytes of 68 patients, including 33 "Shelter" workers after recent radiation exposure in professional limits and comparison group of 35 Chornobyl clean-up workers exposed 24-27 years before, the study by flow cytometry. Results. An increase of the expression of γ-H2AX histone in lymphocytes was revealed in "Shelter" staff after leaving the area of work (0,70±0,93) (M±SD), comparing with Chornobyl clean-up workers (0,51 ± 0,27) (M ± SD), р < 0,001. Analysis subgroups of clean-up workers divided by doses (100-250 mSv, n = 20 and 250-1000 mSv, n = 16) we found connection between radiation dose and the percentage of γ-H2AX positive cells. The number of γ-H2AX positive cells was higher in a subgroup with higher doses (0,49 ± 0,05 and 0,55 ± 0,08, (M ± SD, respectively, p < 0.01)). Conclusions. Our study suggests the possibility of determining γ-H2AX histone as a marker of cellular radiosensitivity and possibility to use it as a diagnostic tool of a recent radiation exposure at low doses in humans.

ABSTRACT

BACKGROUND AND AIMS: Octreotide is suggested to harden the pancreas, thus facilitating the construction of a pancreatic anastomosis and lowering the risk of postoperative fistula. We tested the hypothesis that intra-arterial application of octreotide in the gastroduodenal artery during pancreatectomy may increase pancreatic hardness. MATERIAL AND METHODS: A single-center, prospective, double-blinded, randomized controlled trial with parallel assignment was conducted. Patients planned for a pancreatoduodenectomy or a total pancreatectomy, who had a palpatory and durometer proven (<40 Shore units) soft pancreas, were assigned to receive intraoperatively either 5 mL 500µg octreotide or 5 mL 0.9% saline solution as a bolus injection in the gastroduodenal artery. Pancreatic hardness was measured before, early, and late after intervention. The investigator performing the durometer measurements and pathologist were masked to group assignment. The primary outcome was increased pancreatic hardness. Analysis was by intention to treat. This trial is registered at http://www.clinicaltrials.gov (ID NCT01400100). RESULTS: A total of 12 patients received octreotide and 13 received saline solution. Pancreatic hardness marginally increased in the octreotide group: 0.67 ± 2.3 Shore units, whereas it decreased in the control group: -2.15 ± 2.7 Shore units. The difference was statistically significant, p = 0.029 (95% confidence interval = -4.87 to -0.77). Histology did not find any correlate for this clinically irrelevant hardening effect. CONCLUSIONS: A single bolus application of octreotide did not deliver a clinically relevant increase in pancreatic hardness. Future studies on the hardening effect of octreotide should employ repeated or continuous preoperative administration of this drug.

ABSTRACT

The surveillance of patients with Barrett mucosa in the distal oesophagus leads to an increase of patients diagnosed with early cancer of the oesophagogastric junction and stomach with only superficial infiltration. Comparable to Asian countries where screening of patients at risk is recommended due to the high incidence of gastric cancer, endoscopic resection of early cancer in the stomach and distal oesophagus is increasing. In spite of the special endoscopic techniques--there are several requirements for the resected specimen which ensure its exact pathohistological evaluation. This is necessary to detect the exact depth of infiltration and the resection margins. To provide an exact pathohistological diagnosis is important for further therapeutic implications and prognosis. Advanced carcinomas of the oesophagus and stomach need multimodal treatment with radiation and chemotherapy. This has a special impact on the tumour which leads to pathohistological detectable changes as estimated in the so-called regression grading.

ABSTRACT

BACKGROUND: After pancreatic head resection the reconstruction of small and fragile bile ducts is technically demanding, resulting in more postoperative bile leaks. One option for the reconstruction is the placement of a T-tube drainage at the site of the anastomosis. MATERIAL AND METHODS: Standard reconstruction after pancreatic head resection was an end-to-side hepaticojejunostomy with PDS 5.0, 15-25 cm distally from the pancreaticojejunostomy. For patients with a small bile duct diameter (≤ 5 mm) or a fragile bile duct wall the reconstruction was performed with PDS 6.0 and a T-tube drainage at the side of the anastomosis. RESULTS: The reconstruction with a T-tube drainage at the site of the anastomosis is technically easy to perform and offers the opportunity for immediate visualisation of the anastomosis in the postoperative period by application of water soluble contrast medium. If a bile leak occurs, biliary deviation through the T-tube drainage can enable a conservative management without revisional laparotomy in selected patients. Whether or not a conservative management of postoperative bile leaks will lead to more bile duct strictures is a subject for further investigations. CONCLUSION: A T-tube drainage at the site of the anastomosis can probably not prevent postoperative bile leaks from a difficult hepaticojejunostomy, but in selected patients it offers the opportunity for a conservative management resulting in less re-operations. Therefore we recommend the augmentation of a difficult hepaticojejunostomy with a T-tube drainage.

ABSTRACT

PURPOSE: According to the International Union Against Cancer (UICC), R1 is defined as the microscopic presence of tumor cells at the surface of the resection margin (RM). In contrast, the Royal College of Pathologists (RCP) suggested to declare R1 already when tumor cells are found within 1 mm of the RM. The aim of this study was to determine the significance of the RM concerning the prognosis of pancreatic ductal adenocarcinoma (PDAC). METHODS: From 2007 to 2009, 62 patients underwent a curative operation for PDAC of the pancreatic head. The relevance of R status on cumulative overall survival (OS) was assessed on univariate and multivariate analysis for both the classic R classification (UICC) and the suggestion of the RCP. RESULTS: Following the UICC criteria, a positive RM was detected in 8 %. Along with grading and lymph node ratio, R status revealed a significant impact on OS on univariate and multivariate analysis. Applying the suggestion of the RCP, R1 rate rose to 26 % resulting in no significant impact on OS in univariate analysis. CONCLUSIONS: Our study has shown that the RCP suggestion for R status has no impact on the prognosis of PDAC. In contrast, our data confirmed the UICC R classification of RM as well as N category, grading, and lymph node ratio as significant prognostic factors.

ABSTRACT

PURPOSE: EUS elastography has been used to facilitate the diagnosis of pancreatic cancer, but as yet the interpretation of this procedure has been largely subjective. The present study has been designed to validate a quantitative approach for the analysis of EUS elastography, and to assess its relationship with pancreatic fibrosis. MATERIALS AND METHODS: 86 patients with malignant pancreatic masses and 28 control subjects without any evidence of pancreatic diseases were examined by EUS elastography. EUS video sequences were subjected to a quantitative analysis based on mean hue histogram analysis. Pancreatic fibrosis was determined by quantitative morphometry in tissue specimens from 36 patients. RESULTS: The mean RGB (red, green, blue) value was significantly higher in the cancer patients compared to the controls (14.0 ± 0.4 vs. 11.5 ± 0.9; p = 0.0085), albeit with significant overlap between the groups. In contrast, a much sharper separation between the groups was obtained based on the individual color values for blue, green and red (p < 0.0001, respectively). By these means, 100 % sensitivity and specificity for the distinction between tumor and normal tissue was obtained for the blue color value, while the red and green color values were less discriminative. The fractional fiber content of the tumors was unrelated to the respective hue histogram color values. CONCLUSION: Quantitative EUS elastography allows for clear differentiation between malignant pancreatic tumors and normal tissue. Using this approach, we demonstrated that the stiffness of pancreatic tumors is largely independent of their fiber content.

ABSTRACT

Solid pseudopapillary neoplasms (SPNs) are rare pancreatic tumors. They occur most frequently in young females and are often diagnosed accidentally. SPNs are characterized by an excellent clinical outcome. In our case series the clinical course, pathohistological data and clinical outcome of eight patients (7 female patients, 1 male patient) with SPN are described. Histological examination as well as immunohistochemical analysis shows similar results in all eight cases. Although in the literature a few cases of SPNs with bad prognosis have been reported, up to now none of our patients shows any signs of recurrence or metastasis. Moreover, we give in this case series a summary of SPNs in the literature, important clinical and pathological differential diagnosis, and additionally discuss relevant differential diagnosis occurring in daily routine work.

ABSTRACT

BACKGROUND: The endoscopic totally extraperitoneal (TEP) mesh repair is nowadays a well-established tension-free method for inguinal hernia repair. Mainly based on animal studies and case reports, a concern about the risk of postoperative infertility was expressed. This clinical study aimed to evaluate the risk of infertility due to obstructive azoospermia in men of fertile age who underwent a bilateral hernia repair. METHODS: Over 3 years (2005-2008) 59 male patients, 18-60 years of age, underwent a bilateral TEP repair. Twenty-one of them were prospectively ("light mesh") and 38 retrospectively ("heavy mesh") evaluated for testicular volume and perfusion, serum levels of sexual hormones, ejaculate volume, and number of spermatic cells. Those parameters were determined preoperatively (prospective group) and not earlier than 3 months postoperatively (both groups). RESULTS: No significant difference between pre- and postoperative values was detected in the prospectively studied group. All postoperative parameters were within the normal range in the retrospective group. There was no evidence of impaired fertility in any patient due to the operation. CONCLUSION: The standardized TEP technique for simultaneous bilateral inguinal hernia repair in male patients was not associated with a higher risk for postoperative infertility after mesh implantation. The use of heavy-weight meshes had no negative effect on fertility.

ABSTRACT

Advances in pancreatic surgery during the last two decades have resulted in significant improvement of patient outcome leading to mortality rates as low as 3-5% following Whipple's procedure in specialized centers. However, morbidity remains considerably high at 30-50% which is primarily caused by insufficiency of the pancreato-enteric anastomosis which becomes manifested as a pancreatic fistula. Therefore, numerous studies have aimed to identify the ideal pancreatic anastomosis. The most frequently used techniques comprise end-to-end duct-to-mucosa pancreaticojejunostomy, end-to-end invagination pancreatojejunostomy as well as end-to-side pancreatogastrostomy. In randomized controlled trials the frequency of pancreatic fistulas ranges between 4% and 20% depending on the particular technique. However, no single technique was able to demonstrate a significant superiority in several independent studies. The heterogeneity of definitions for pancreatic fistula represents the main problem in evaluating and comparing clinical studies on pancreato-enteric anastomosis. However, recent clinical trials applied commonly accepted definitions for pancreatic fistula as well as precise study endpoints to address the question of the ideal pancreatic anastomosis.

ABSTRACT

INTRODUCTION: Diverticular disease of the colon is a common condition in developed countries. For perforated diverticulitis Hartmann's procedure is a safe and quick treatment option. But intestinal restoration needs further interventions. This leads to high complication rates and cost. Therefore a critical evaluation of surgical treatment options is necessary. METHODS: During a period of 18 months 88 patients underwent surgical resection for diverticulitis. Forty patients had emergency surgery. Among those a primary anastomosis was performed in 21 patients. The other 19 patients had interval colostomy. Among 21 patients with primary anastomosis major complications occurred in two patients, vs. twelve in patients with Hartmann's operation (p = 0.03). In the Hartmann group eight patients had major general complications, vs. one patient in the group with primary anastomosis (p = 0.06). The mean hospital stay was 38 days after Hartmann's procedure, vs. 13 days for patients with primary anastomosis (p < 0.01). CONCLUSION: In emergency surgery for complicated diverticulitis primary anastomosis is not associated with an increased postoperative morbidity. A primary anastomosis reduces the need for further surgical interventions and complex re-operations. Thus, an overall reduction of morbidity, cost, complication rate and hospital stay is possible. Therefore this technique is advantageous for patients and hospitals.

ABSTRACT

BACKGROUND: The concept of total mesorectal excision has revolutionised rectal cancer surgery. TME reduces the rate of local recurrence and tumour associated mortality. However, in clinical trials only 50% of the removed rectal tumours have an optimal TME quality. PATIENTS: During a period of 36 months we performed 103 rectal resections. The majority of patients (76%; 78/103) received an anterior resection. The remaining patients underwent either abdominoperineal resection (16%; 17/103), Hartmann;s procedure (6%; 6/103) or colectomy (2%; 2/103). RESULTS: In 90% (93/103) TME quality control could be performed. 99% (92/93) of resected tumours had optimal TME quality. In 1% (1/93) the mesorectum was nearly complete. None of the removed tumours had an incomplete mesorectum. In 98% (91/93) the circumferential resection margin was negative. Major surgical complications occurred in 17% (18/103). 5% (4/78) of patients with anterior resection had anastomotic leakage. 17% (17/103) developed wound infections. Mortality after elective surgery was 4% (4/95). CONCLUSION: Optimal TME quality results can be achieved in all stages of rectal cancer with a rate of morbidity and mortality comparable to the results from the literature. Future studies should evaluate outcome and local recurrence in accordance to the degree of TME quality.

ABSTRACT

Intraductal papillary mucinous neoplasms (IPMN) are the most common cystic tumours of the pancreas. The preoperative diagnosis of IPMN malignancy is difficult and the majority of IPMN are malignant upon diagnosis. Thus, only the early radical resection of the pancreas with regional lymph node dissection offers the patient a chance for cure. A discussion of the type "to resect or not to resect" should, furthermore, be held only within the walls of high-volume pancreatic centres and patients managed by the "watchful waiting" strategy (mainly branch-duct type IPMN) should all be recruited into large randomised controlled trials aimed to discover reliable diagnostic criteria to differentiate between invasive and non-invasive IPMN. Until then an aggressive surgical approach should be recommended as the standard treatment for all patients with IPMN.

ABSTRACT

The case of a female patient with a covered double perforation of the sigmoid colon is described. The perforation was due to a migrated plastic biliary stent inserted 3 weeks earlier for benign biliary obstruction and was facilitated by the presence of expressed diverticulosis of the colon. The lack of peritonitis and the early surgical procedure allowed a successful primary reconstruction after the colonic resection. Since the use of biliary stents is constantly increasing, such complications as stent migration and perforation should always be kept in mind by surgeons.
