Background Obese patients are a very large high-risk group for complications after surgical procedures. In this group, optimized perioperative care and a faster recovery to full activity can contribute to a decreased rate of postoperative complications. The introduction of ERAS®-based protocol is now even more important in bariatric surgery centers. The results of our study support the idea of implementation of ERAS®-based protocol in this special group of patients. Material/Methods This analysis included 170 patients (62 male/108 female, mean BMI 46.7 kg/m2) who had undergone laparoscopic bariatric surgery, and whose perioperative care was conducted according to a protocol inspired by ERAS® principles. Examined factors included oral nutrition tolerance, time until mobilization after surgery, requirements for opioids, duration of hospitalization, and readmission rate. Results During the first 24 postoperative hours, oral administration of liquid nutrition was tolerated by 162 (95.3%) patients and 163 (95.8%) were fully mobile. In 44 (25.8%) patients it was necessary to administer opioids to relieve pain. Intravenous liquid supply was discontinued within 24 hours in 145 (85.3%) patients. The complication rate was 10.5% (mainly rhabdomyolysis and impaired passage of gastric contents). The average time of hospitalization was 2.9 days and the readmission rate was 1.7%. Conclusions The introduction of an ERAS® principles-inspired protocol in our center proved technically possible and safe for our patients, and allowed for reduced hospitalization times without increased rate of complications or readmissions.

Background Enhanced Recovery After Surgery (ERAS) protocol are well established in many surgical disciplines, leading to decrease in morbidity and length of hospital stay. These multi-modal protocols have been also introduced to oesophageal cancer surgery. This review aimed to evaluate current literature on ERAS in oesophageal cancer surgery and conduct a meta-analysis on primary and secondary outcomes. Methods MEDLINE, Embase, Scopus and Cochrane Library were searched for eligible studies. We analyzed data up to May 2016. Eligible studies had to contain four described ERAS protocol elements. The primary outcome was overall morbidity. Secondary outcomes included length of hospital stay, specific complications, mortality and readmissions. Random effect meta-analyses were undertaken. Results Initial search yielded 1,064 articles. Thorough evaluation resulted in 13 eligible articles which were analyzed. A total of 2,042 patients were included in the analysis (1,058 ERAS group and 984 treated with traditional protocols). Analysis of overall morbidity as well as complication rate did not show any significant reduction. Non-surgical complications and pulmonary complications were significantly lower in the ERAS group, RR = 0.71 95% CI 0.62–0.80, p < 0.00001 and RR = 0.75, 95% CI 0.60–0.94, p = 0.01, respectively. Meta-analysis on length of stay presented significant reduction Mean difference = -3.55, 95% CI -4.41 to -2.69, p for effect<0.00001. Conclusions This systematic review with a meta-analysis on ERAS in oesophageal surgery indicates a reduction of non-surgical complications and no negative influence on overall morbidity. Moreover, a reduction in the length of hospital stay was presented.

PurposeThree-dimensional (3D) printing for preoperative planning has been intensively developed in the recent years. However, the implementation of these solutions in hospitals is still difficult due to high costs, extremely expensive industrial-grade printers, and software that is difficult to obtain and learn along with a lack of a defined process. This paper presents a cost-effective technique of preparing 3D-printed liver models that preserves the shape and all of the structures, including the vessels and the tumor, which in the present case is colorectal liver metastasis.MethodsThe patient’s computed tomography scans were used for the separation and visualization of virtual 3D anatomical structures. Those elements were transformed into stereolithographic files and subsequently printed on a desktop 3D printer. The multipart structure was assembled and filled with silicone. The patient underwent subsequent laparoscopic right hemihepatectomy. The entire process is described step-by-step, and only free-to-use and mostly open-source software was used.ResultsAs a result, a transparent, full-sized liver model with visible vessels and colorectal metastasis was created for under

Introduction Not only did the introduction of laparoscopy not dispel the controversy over routine drainage after uncomplicated surgery, but paradoxically it contributed to enlivening the debate on the issue. Aim To determine the usefulness of operative site drainage after “clean”, uncomplicated laparoscopic surgery such as splenectomy or adrenalectomy. Material and methods One hundred and seventy-six participants (female : male 114 : 62) operated on in our centre between Jan 2008 and Nov 2010 were included in the prospective study. Adrenalectomy was performed in 122 patients and splenectomy in 54. In some patients no drains were left after the procedure, while the others had drainage employed. The incidence and character of post-operational complications, the necessity of repeat surgery and the length of the hospital stay were analysed. Results In 112 patients (63.6%) the drain was inserted in the operational field, while in the remaining 64 (36.4%) it was not. Out of the whole series of 112 patients with drainage used, complications were observed in 6 cases (5.36%) while in the group of patients without drainage they appeared in 2 (3.12%) of those operated on (p < 0.05). Infectious complications were observed more often in the series with drainage (3.57% vs. 0%, p < 0.05). The hospital stay in patients with drainage was statistically significantly longer than in patients without. Conclusions Based on the study, no justification for routine drainage after scheduled, uncomplicated laparoscopic adrenalectomy and splenectomy was found. The decision whether to leave a drain should be made for every patient individually.

BACKGROUND The growing need for surgeons who are educated and trained in bariatric surgery has raised many issues related to training in this field. OBJECTIVES This study was performed to evaluate the safety and efficacy of laparoscopic sleeve gastrectomy (SG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) performed by doctors-in-training during their residency in general surgery. SETTING Tertiary referral university teaching hospital, Poland. METHODS We retrospectively analyzed the data of patients who underwent bariatric surgery. One group underwent surgery performed by at least third-year residents learning particular types of surgeries (trainee group), and the second group underwent surgeries performed by experienced bariatric surgeons (mentor group). The primary endpoint was the safety of the procedures. We analyzed factors related to the intraoperative and postoperative course. The secondary endpoint was long-term weight reduction. A lower body mass index (BMI), fewer co-morbidities, and preferably female sex were the selection criteria for patients in the trainee group. RESULTS We enrolled 408 patients who met all inclusion criteria. Among them, 233 underwent SG and 175 underwent LRYGB. For both SG and LRYGB, the median maximum preoperative weight was significantly lower in the trainee than mentor group. We found no statistically significant differences in the demographic factors or co-morbidities between the 2 groups. The median duration of SG and LRYGB surgery was significantly longer in the trainee than mentor group. The median number of stapler firings during SG was significantly lower in the trainee than mentor group. The number of stapler firings during LRYGB did not differ between the 2 groups. The incidence of intraoperative difficulties, which were based on the operators subjective opinion, was higher in the trainee than mentor group for both SG and LRYGB. However, intraoperative difficulties had no significant impact on the intraoperative complication rate or risk of perioperative complications. The average percentage weight loss (%WL), percentage excess weight loss (%EWL), and percentage excess BMI loss (%EBMIL) in the all study group were 31.14%±9.11%, 56.17%±17.27%, and 65.42%±19.28%, respectively. For patients who underwent SG, we found no significant difference in %WL, %EWL, or %EBMIL between the trainee and mentor groups. CONCLUSIONS The performance of bariatric surgeries by residents does not affect the risk of reoperation, intraoperative adverse events, or surgical complications. Performance of SG and LRYGB by trainees takes significantly longer but has no untoward consequences for the patient. Both SG and LRYGB performed by a doctor-in-training and experienced operator lead to comparable outcomes in terms of weight reduction.

INTRODUCTION Progressive skeletal muscle loss (sarcopenia) is a negative prognostic factor in patients treated for colorectal cancer. Nevertheless, the clinical impact of those changes in body composition has been analyzed only in patients undergoing open resections. The aim of the study was to assess whether laparoscopy may eliminate the deleterious prognostic impact of sarcopenia and whether the combination with enhanced recovery after surgery (ERAS) protocol may improve postoperative recovery also in sarcopenic patients. METHODS The study included 124 (73M/51F, mean age 65.9 years) patients undergoing elective laparoscopic colorectal resection for cancer. In all of them 16-item ERAS protocol was applied. The L3 skeletal muscle area identified on a preoperative CT scan was used to calculate skeletal muscle index and assess for sarcopenia and myosteatosis. The entire study group was divided into groups regarding the presence of sarcopenia or myosteatosis. The outcome measures were: length of hospital stay, complication rate and functional recovery parameters. RESULTS The prevalence of sarcopenia and myosteatosis was 27.4% and 38.7%, respectively. There was no association between the presence of sarcopenia or myosteatosis and postoperative complications. There were also no differences in the length of stay or readmission rates. Functional recovery (time to first flatus, oral diet tolerance and mobilization) was similar regardless of the presence of muscle depletion. CONCLUSIONS In contrary to traditional surgical approach, laparoscopy can reduce the negative impact of sarcopenia and myosteatosis on treatment results. ERAS protocol does not affect negatively the surgical outcomes in sarcopenic patients, compared to patients without changes in body skeletal mass.

Introduction The elderly will soon constitute 20% of the population. Their number is constantly rising, particularly in developed countries. It was found that they particularly benefit from the use of minimally invasive surgery. The Enhanced Recovery After Surgery (ERAS) protocol may further improve clinical outcomes in this group of patients. Aim To assess the implementation of the ERAS protocol in elderly patients submitted to laparoscopic colorectal surgery. Material and methods Ninety-two patients who underwent elective laparoscopic colorectal surgery were included in the study. Patients were divided into group 1 (≤ 65 years) and group 2 (> 65 years). Perioperative care was based on ERAS Society guidelines. Length of hospital stay, time of first stool passage, perioperative complications and readmissions were analyzed. Results Group 2 patients had higher ASA grades in comparison to group 1. In all cases, oral fluid intake started on the day of surgery. The groups did not differ according to oral fluid tolerance, first stool passage time or length of hospital stay. Number and character of perioperative complications were comparable between the two groups. Four patients were readmitted within 30 days after discharge. One patient required reoperation. Conclusions Implementation of the ERAS protocol is possible regardless of the age of surgical patients. Its use in the elderly allows the length of hospitalization to be shortened and is not associated with higher risk of postoperative complications or readmissions.

PurposeThe purpose of this systematic review was to compare minimally invasive pancreatoduodenectomy (MIPD) versus open pancreatoduodenectomy (OPD) by using meta-analytical techniques.MethodologyMedline, Embase, and Cochrane Library were searched for eligible studies. Data from included studies were extracted for the following outcomes: operative time, overall morbidity, pancreatic fistula, delayed gastric emptying, blood loss, postoperative hemorrhage, yield of harvested lymph nodes, R1 rate, length of hospital stay, and readmissions. Random and fix effect meta-analyses were undertaken.ResultsInitial reference search yielded 747 articles. Thorough evaluation resulted in 12 papers, which were analyzed. The total number of patients was 2186 (705 in MIPD group and 1481 in OPD). Although there were no differences in overall morbidity between groups, we noticed reduced blood loss, delayed gastric emptying, and length of hospital stay in favor of MIPD. In contrary, meta-analysis of operative time revealed significant differences in favor of open procedures. Remaining parameters did not differ among groups.ConclusionOur review suggests that although MIPD takes longer, it may be associated with reduced blood loss, shortened LOS, and comparable rate of perioperative complications. Due to heterogeneity of included studies and differences in baseline characteristics between analyzed groups, the analysis of short-term oncological outcomes does not allow drawing unequivocal conclusions.

Introduction Laparoscopic technique combined with the ERAS (Enhanced Recovery after Surgery) protocol enables a shorter hospital stay and a lower complication rate. Although it has been widely used in many patients undergoing elective abdominal surgery, especially in patients with colorectal cancer, there are only a few papers describing laparoscopic total gastrectomy and the enhanced recovery protocol in patients with gastric cancer. Minimally invasive gastrectomy is still an uncommon procedure, mostly because of its difficulty. Aim To present the preliminary results of treatment of patients with gastric neoplasms who underwent laparoscopic gastrectomy D2 with perioperative care according to ERAS principles. Material and methods Eleven patients (5 male and 6 female, age 52–77 years) underwent laparoscopic D2 gastrectomy with intracorporeal esophagojejunal anastomosis. In all patients the ERAS protocol was implemented. We analyzed operation time, complications and hospital stay. Additionally we focused on operative technique as well as the perioperative care protocol. Results The mean duration of the procedure was 245 min. There was 1 conversion due to unclear tumor infiltration. Mean hospital stay was 4.6 days. One postoperative complication (central venous catheter sepsis) was reported. Histological analysis confirmed the tentative diagnosis (R0 resection) in 10/11 patients. There were no readmissions. Conclusions Laparoscopic gastrectomy is a valuable alternative to the classical approach and combined with the ERAS protocol can result in reduced hospital stay. However, due to the small group of patients it is difficult to adequately assess the incidence of early and late complications of the laparoscopic procedures; therefore further research is needed.
