Background: Preoperative classification of complicated and uncomplicated appendicitis (AA) is challenging. However, the differences in surgical outcomes necessitate the establishment of risk factors in developing, complicated AA. This study was an analysis of the clinical outcomes of laparoscopic appendectomies (LA), as well as preoperative risk factors for the development of complicated AA., Methods: The data of 618 patients who underwent LA in 18 surgical units across Poland and Germany were collected in an online web-based database created by the Polish Videosurgery Society. The surgical outcomes of patients with complicated and uncomplicated appendicitis were compared. Uni- and multivariate logistic regression models were used to establish risk factors for the development of complicated appendicitis., Results: In all, 1269 (27.5%) patients underwent LA for complicated appendicitis (Group 1) and 3349 (72.5%) for uncomplicated appendicitis (Group 2). The conversion rate, number of intra-operative adverse events, re-intervention rate, postoperative complications, and readmission rate was greater in Group 1. The preoperative risk factors associated with complicated appendicitis were: female sex (Odds ratio [OR]: 1.58), obesity (OR: 1.51), age >50 years (OR: 1.51), symptoms >48 hours (OR: 2.18), high Alvarado score (OR: 1.29 with every point), and C-reactive protein level >100 mg/L (OR: 3.92)., Conclusion: Several demographic and clinical risk factors for complicated AA were identified. LA for complicated appendicitis was associated with poorer outcomes.

Introduction: According to meta-analyses laparoscopic appendectomy is associated with many benefits. However, in comparison to open surgery an increased rate of intraabdominal abscesses (IAA) has been reported. Identification of predictive factors for this complication may help to identify patients with higher risk of IAA., Aim: To identify potential risk factors for intraabdominal abscess after laparoscopic appendectomy (LA)., Material and Methods: Eighteen surgical units in Poland and Germany submitted data of patients undergoing LA to the online web-based database created by the Polish Videosurgery Society of the Association of Polish Surgeons. It comprised 31 elements related to the pre-, intra- and postoperative period. Surgical outcomes were compared among the groups according to occurrence of IAA. Univariate and multivariate logistic regression models were used to identify potential risk factors for IAA., Results: 4618 patients were included in the analysis. IAA were found in 51 (1.10%) cases. Although several risk factors were found in univariate analysis, in the multivariate model, only the presence of complicated appendicitis was statistically significant (OR = 2.98, 95% CI: 1.11-8.04). Moreover, IAA has a significant influence on postoperative reintervention rate (OR = 126.95, 95% CI: 67.98-237.06), prolonged length of stay > 8 days (OR = 41.32, 95% CI: 22.86-74.72) and readmission rate (OR = 33.89, 95% CI: 18.60-34.73)., Conclusions: Intraabdominal abscesses occurs relatively rarely after LA. It is strongly associated with complicated appendicitis. Occurrence of this complication has a great influence on the postoperative period and due to the nature of its treatment is associated with the need for reintervention, prolonged length of stay and by extension possible readmission.

Breast cancer has high metastatic potential with distant metastases involving mainly lungs, liver and bones. Less frequently it gives distant spread to other organs. Herein we would like to present a very rare case of an acute cholecystitis which turned out to be a metastatic breast cancer in previously healthy woman. A female patient, 64-years old, presented to the emergency department with symptoms of biliary colic and acute abdomen. During the emergency cholecystectomy, we diagnosed the gallbladder empyema with thickened wall. There were also multiple metastatic nodules in the peritoneal cavity and an excessive amount of free fluid. The emergency physicians diagnosing female patient with the acute abdominal symptoms and a breast cancer history might suspect malignant spread into abdominal organs including gallbladder. On the other hand, acute cholecystitis symptoms might be the first symptoms of metastatic process in the gallbladder from the unknown primary source, which may be breast.

More than 1 million inguinal hernia repairs are performed in Europe and the US annually. Although antibiotic prophylaxis is not required in clean, elective procedures, the routine use of implants (90% of inguinal hernia repairs are performed with mesh) makes the topic controversial. The European Hernia Society does not recommend routine antibiotic prophylaxis for elective inguinal hernia repairs. However, the latest randomized controlled trial, published by Mazaki et al., indicates that the use of prophylaxis is effective for the prevention of surgical site infection. Unnecessary prophylaxis contributes to the development of bacterial resistance and significantly increases healthcare costs. This review documents clinical trials on inguinal hernia repairs with mesh and summarizes the current knowledge. It also tries to solve certain problems, namely: what constitutes a real risk factor, late-onset infection, and how the "surgical environment" impacts on the need to use antibiotic prophylaxis., Competing Interests: The authors declare no conflict of interest.

Introduction: Absent today is a simple numerical system of outcomes assessment that recognizes that bariatric surgery is metabolic surgery and incorporates weight loss, hypertension control, and type 2 diabetes control., Aim: To introduce a simple, new Numerical Scale to Assess the Outcomes of Metabolic Surgery (NOMS)., Material and Methods: For the stratification of weight outcomes, we used the percentage excess weight loss (%EWL); for hypertension, the systolic blood pressure (SBP) and diastolic blood pressure (DBP) combined with medication usage; and for type 2 diabetes, the hemoglobin A1c (HbA1c) value combined with medication usage., Results: Utilizing the guidelines of the American Diabetes Association, the Working Group of the European Society of Hypertension, the European Society of Cardiology, and the American College of Cardiology/American Heart Association, we propose for %EWL: W1 ≥ 50, W2 > 25 and < 50, and W3 ≤ 25; for hypertension H1 SBP/DPB < 140/90 mm Hg on no medication, H2 SBP/DBP ≥ 140/90 mm Hg with improvement of SBP or possible reduction of antihypertensive medication, and H3 no change or SBP higher than before surgery; for diabetes mellitus D1 HbA1c ≤ 7% and no medication, D2 HbA1c > 7% with a decrease of the HbA1c level or possible reduction of medication, D3 no change in HbA1c or HbA1c higher than before surgery. Designations of H0 and D0 are given if hypertension or diabetes was not present before surgery. Patient examples for numerical scores are provided., Conclusions: The introduction of our numerical scale (NOMS) can be of benefit in metabolic/bariatric outcomes assessment; communications among metabolic/bariatric surgery centers, physicians, and patients; and for more precise reporting in the evidence-based literature.

Introduction: Pleural empyema is the most serious, life-threatening postoperative complication of pneumonectomy, observed after 1-12% of all pneumonectomies, with bronchopleural fistula being its main cause., Aim: The aim of this publication is to present early outcomes of minimally invasive surgical management of pleural empyema. Patients were subjected to a single, complex procedure, consisting of the laparoscopic mobilization of the greater omentum and its transposition via the diaphragm into the pleural cavity to fill in the empyema cavity with the consecutive pleuro-cutaneous fistuloplasty (thoracoplasty)., Material and Methods: Between May 2011 and April 2013, 8 patients were qualified to undergo the procedure. The mean age was 61 years (range: 46-77 years). Presence of bronchopleural fistula was confirmed in 3 cases. The median time of treatment with thoracostomy was 14.5 months., Results: The mean operative time was 125 min. The mean duration of post-operative hospital stay was 13.5 days (range: 7-31 days). In 6 patients (75%) the objective of permanent resolution of pleural empyema was achieved. In total, 4 patients had complications: pleural empyema recurrence (2 patients), splenic injury, hiatal hernia, gastrointestinal bleed. Two patients with empyema recurrence had Staphylococcus aureus infections prior to surgery. They were successfully managed both with prolonged thoracic drainage and antibiotics., Conclusions: Use of the greater omentum that was laparoscopically mobilized and transpositioned into the pleural cavity allows simultaneous management of the pleural empyema cavity and thoracostomy. The procedure is safe, with few direct complications. It is well tolerated and has at least a satisfactory cosmetic effect. The minimally invasive approach allows faster recovery and return to daily activities in comparison to the fully open technique.

Introduction: Laparoscopic sleeve gastrectomy (LSG) and laparoscopic adjustable gastric banding (LAGB) are acceptable options for primary bariatric procedures in patients with body mass index (BMI) 35-55 kg/m(2)., Aim: The aim of this study is to compare the effects of these two bariatric procedures 6, 12 and 24 months after surgery., Material and Methods: Two hundred and two patients were included 72 LSG and 130 LAGB patients. The average age was 38.8 ±11.9 and 39.4 ±10.4 years in LSG and LAGB groups, with initial BMI of 44.1 kg/m(2) and 45.2 kg/m(2), p = NS., Results: The mean percentage of excess weight loss (%EWL) at 6 months for LSG vs. LAGB was 36.3% vs. 30.1% (p = 0.01) and at 12 months was 43.8% vs. 34.6% (p = 0.005). The greatest difference in the mean %EWL at 12 months was observed in patients with initial BMI of 40-49.9 kg/m(2) in favor of LSG (47.5% vs. 35.6%; p = 0.01). Two years after surgery there was no advantage of LSG and in the subgroup of patients with BMI 50-55 kg/m(2) there was a trend in favor of LAGB (57.2% vs. 30%; p = 0.07). The multiple regression model of independent variables (age, gender, initial BMI and the presence of comorbidities) proved insignificant in prediction of the best outcome in means of %EWL for either operative modality. None of these factors in the logistic regression model could determine the type of surgery that should be used in particular patients., Conclusions: During the first 2 years after surgery, the best results were obtained in women with lower BMI undergoing LSG surgery. The LSG provides greater %EWL after a shorter period of time though the difference decreases in time.

Introduction: Hemorrhoidal disease is one of the commonest anorectal disorders worldwide. Stapled hemorrhoidopexy (SH) is a treatment modality associated with low postoperative pain and early mobilization., Aim: To assess long-term outcomes after SH., Material and Methods: All 326 patients who underwent SH in 1999-2003 were invited by mail to participate. For each patient we analyzed their medical records, and conducted a questionnaire survey and a digital rectal examination., Results: Only 91 patients attended the final examination and the mean ± SD follow-up time was 8.7 ±1.2 years. Recurrences were diagnosed in one third of the 91 subjects. There were correlations between recurrences and: the duration of disease (p = 0.047); female gender (p = 0.037); and childbirth (vaginal delivery) (p = 0.026). Sixty-seven patients (73.6%) were satisfied with the outcomes. In the group of dissatisfied patients symptoms such as pain (p = 0.0001), burning (p = 0.0002) and itching (p = 0.014) were most common. Long-term outcomes were good with 75% and 88% reductions in pain sensation and severe and moderate hemorrhoidal bleeding. Pruritus, burning and discomfort resolved in more than 50% of patients. Flatus incontinence, fecal incontinence, or soiling occurred in 21%, 11%, and 32% of patients., Conclusions: Long-term results of stapled hemorrhoidopexy are satisfactory in most patients. The 36% recurrence rate correlates with the degree of hemorrhoidal prolapse before the operation, duration of the disease, female gender, and previous vaginal delivery.

Introduction: With the introduction of new surgical equipment, there is always the need for new, more advanced training. The authors try to answer whether the use of the newest generation tools has an impact on achieving better results in single incision laparoscopic surgery (SILS) technique during the exercises in the surgical skills laboratory., Material and Methods: There were 51 participants in the study: 44 'novices' and 7 'experts'. All subjects performed the 'advanced grasping' exercise according to the FLS programme manual using four types of laparoscopic approach including two SILS ports and SILS-dedicated instruments. The outcome measures involved task completion time and the number of errors., Results: Tasks using straight laparoscopic instruments set together with classic three-port access as well as SILS access ports were finished significantly faster when compared with SILS-dedicated instruments (p < 0.05). There were no significant differences in performance times between the two setups with straight instruments (p < 0.05) and both setups with SILS-dedicated instruments, irrespective of the use of curved or dynamic articulated tools. Students with no previous laparoscopic experience had significantly worse task completion times in all tasks in comparison to students with laparoscopic laboratory training and the 'experts' group., Conclusions: The use of the straight instruments in the SILS technique remain similar to its performance in full triangulation. SILS-dedicated instruments paradoxically increase the task completion time irrespective of possessed skills. The study showed the necessity of a SILS-dedicated tools training programme.

Unlabelled: Over the last decade, gastric cancer treatment has changed from extensive multiorgan resections towards less invasive approaches with limited resections and a more selective lymphadenectomy. Despite all available trials, the conclusions on the extent of necessary resections still remain debatable. The aim of the study was to assess the short term outcomes (morbidity and mortality) of a total gastrectomy depending on the simultaneous splenectomy status., Material and Methods: We performed a retrospective analysis of the records of all patients treated with a curative intent using a total gastrectomy for gastric cancer between 1997 and 2003. 49 patients fulfilled the inclusion criteria. Patients were divided into two groups: S(+) gastrectomy with splenectomy group (29 patients) and S(-) total gastrectomy with spleen preservation (20 patients)., Results: Survival analysis at one year showed that there was no difference in survival between the two groups (p=0.84). There were six recurrences, one in the group S(+) and five in group S(-) (p>0.05). Dissemination was observed in three patients in group S(-) (p>0.05). Other complications including infectious complications, exenteration, subileus, cardiovascular insufficiency, multiorgan failure were more frequent in the S(+) group (31% v 15%) although the difference was not significant (p=0.17)., Conclusions: Splenectomy during gastrectomy for cancer has no statistically significant impact on short-term morbidity and mortality. Even though it does not show benefit in terms of 5-year overall survival rates it might be performed when needed in more advanced cases in properly selected patients (e.g. upper gastric T3/4 gastric cancer).

For many years, laparoscopic cholecystectomy remains the method of choice for both the treatment of symptomatic cholelithiasis, and chronic and acute cholecystitis (1). The experience of the surgeon grows with each laparoscopic procedure, which enables to operate in case of difficult anatomical conditions and associated anatomical variants. The aim of the study was to present a case of a 47-year old male patient with total situs inversus and several months history of recurrent left epigastric pain, radiating to the left scapula, being accompanied by nausea and vomiting. The study presented the operative technique of laparoscopic cholecystectomy and postoperative period data. In conclusion, laparoscopic cholecystectomy in a patient with total situs inversus is possible and safe, providing relevant precautions. The main issues certainly include a good and feasible plan of the operation, discussion concerning the possible intraoperative and postoperative complications, a good plan considering the localization of the trocars, as well as an experienced surgical team. One should also not forget that early conversion to classical cholecystectomy is not considered as failure, but might prevent accidental damage of the biliary ducts and long-term complications.

Introduction: Laparoscopic adjustable gastric banding (LAGB) is considered to be a very effective minimally invasive procedure for treating morbidly obese patients. Nevertheless, there are numerous complications that a good surgeon should be aware of. Most of them have been widely presented in the literature., Aim: In this study we would like to focus on the rare but important complication which is ante-gastric positioning of the band., Material and Methods: Between January 2005 and May 2008, 122 patients (88 female and 34 male) with mean body mass index (BMI) of 48.5 kg/m(2) (range 35-80 kg/m(2)) underwent LAGB procedure. The average time of hospitalization was 2.47 days. The first radiological control with band calibration was performed 6 weeks after the operation. Consecutive follow-up depended on the percent excess weight loss (EWL%)., Results: Of the 122 patients, 4 (3.3%) presented herein had a band misplaced in the ante-gastric position. There were three out of five surgeons who faced complications of this type. The most and the least experienced team members avoided misplacing the band. Two physicians encountered it at the beginning of their learning curve, and for one it was not related to the process of education. Among other postoperative complications there were two incidents of band slippage, 2 patients had their port localization corrected and in one case drain disconnection occurred. There were no mortalities., Conclusions: Ante-gastric positioning of the band was the most common cause of obesity surgery failure in our group of patients. It was very difficult to recognize during the typical postoperative checkups; hence there arose a question whether it has been disregarded in other studies.
