Enhanced recovery after surgery protocol in oesophageal cancer surgery: Systematic review and meta-analysis

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.

SILS (Single Incision Laparoscopic Surgery) – new surgical approach to peritoneal cavity

PURPOSE The objective of the modern surgery is not only to perform surgical procedures aiming to improve the health condition of the patient, but whenever possible to use minimally invasive approach and to ensure the satisfying cosmetic result. During the last years we can observe an intense development of surgical technique minimizing the access to peritoneal cavity to just one small incision, most frequently localized in the umbilicus. MATERIAL/METHODS Between October 2009 and May 2010 an overall number of 34 laparoscopic procedures through a single abdominal wall incision were performed at the 2nd Department of Surgery, Jagiellonian University, Medical College in Krakow. There were 28 women and 6 men in the study group ranging in age from 19 - 76 years. Among indications for surgery there were: symptomatic gallbladder stones (21 patients), adrenal gland tumours (8 patients), ITP - Immune Thromocytopenic Purpura (2 patients), appendicitis (2 patients) and splenic cyst (one patient). RESULTS There were 31 out of 34 procedures completed with pure Single Incision Laparoscopic Surgery (SILS) technique as intended preoperatively without any intraoperative complications. In 3 patients additional trocars were needed for safe continuation of the procedure. There were no intraoperative complications. The mean operating time was 82 minutes ranging from 25 minutes (appendectomy) to 180 minutes (right adrenalectomy). Mean intraoperative blood loss was 0 - 30 ccm. CONCLUSIONS SILS surgical procedures constitute the next step in the development of minimally invasive surgery. In the hands of experienced surgeon this particular technique may constitute a safe alternative for classical laparoscopy.

Ghrelin and gastrin in advanced gastric cancer before and after gastrectomy

AIM To investigate plasma ghrelin, gastrin and growth hormone secretagogue receptor (GHS-R) expression in advanced gastric cancer (GC) before and after resection. METHODS Seventy subjects in whom endoscopy of the upper gastrointestinal tract was performed in the Department of General Surgery at Cracow University during the past decade: (1) 25 patients with GC associated with Helicobacter pylori (H. pylori) infection; (2) 10 patients with GC 4-5 years after (total or subtotal) gastrectomy; (3) 25 healthy H. pylori-negative controls, matched by age and BMI to the above two groups; and (4) 10 GC patients 4-5 years after total gastrectomy. Ghrelin and gastrin plasma concentrations were measured by specific radioimmunoassay under fasting conditions and postprandially at 60 and 90 min after ingestion of a mixed meal. GHS-R expression was examined in biopsy samples from intact healthy mucosa and GC tissue using semi-quantitative reverse transcription-polymerase chain reaction. RESULTS In healthy controls, fasting plasma ghrelin levels were significantly elevated and declined markedly at 60 and 90 min after a mixed meal. The concomitant enhanced ghrelin, GHS-R and gastrin expression in GC tissue over that recorded in intact mucosa, and the marked rise in plasma gastrin in these subjects under fasting conditions indicate the role of these hormonal factors in GC formation. Fasting plasma levels and postprandial response of ghrelin and gastrin appear to be inversely correlated in healthy subjects. Feeding in the controls resulted in a significant fall in plasma ghrelin with a subsequent rise in plasma gastrin, but in H. pylori-positive GC patients submitted to total or distal gastrectomy, feeding failed to affect significantly the fall in plasma ghrelin that was recorded in these patients before surgery. Fasting ghrelin concentrations were significantly lower in patients 4-5 years after total gastrectomy compared to those in healthy controls and to these in GC patients before surgery. CONCLUSION Elevated plasma gastrin and suppression of fasting ghrelin in patients with GC suggest the existence of a close relationship between these two hormones in gastric carcinogenesis.

Cost-effective, personalized, 3D-printed liver model for preoperative planning before laparoscopic liver hemihepatectomy for colorectal cancer metastases

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

Do we really need routine drainage after laparoscopic adrenalectomy and splenectomy

150, which—taking into account 3D printer prices—is much cheaper than models presented in previous research papers.ConclusionsThe increased accessibility of 3D models for physicians before complex laparoscopic surgical procedures such as hepatic resections could lead to beneficial breakthroughs in these sophisticated surgeries, as many reports show that these models reduce operative time and improve short term outcomes.

Sclerosing angiomatoid nodular transformation of the spleen treated by laparoscopic partial splenectomy

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.

Are bariatric operations performed by residents safe and efficient

The authors describe a case of sclerosing angiomatoid nodular transformation (SANT) of the spleen treated at the 2nd Department of Surgery, Jagiellonian University, Medical College. The patient was a 23-year-old woman. Clinically she presented with 2-year history of recurrent mild fever, diffuse joint pain, abdominal discomfort and iron deficiency anaemia of chronic disease. The laboratory tests revealed a non-characteristic chronic inflammatory response. A splenic solid lesion 9 cm in diameter was found on abdominal computed tomography. The patient underwent uneventful laparoscopic resection of the upper half of the splenic parenchyma. The resected tumour showed characteristic histological and immunophenotypical findings of SANT as previously described in the literature. In long-term follow-up, improvement of preoperative symptoms and abnormalities in the blood tests was documented.

Laparoscopic colorectal cancer surgery combined with enhanced recovery after surgery protocol (ERAS) reduces the negative impact of sarcopenia on short-term outcomes

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.

Enhanced recovery after colorectal surgery in elderly patients

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.

Minimally invasive versus open pancreatoduodenectomy—systematic review and meta-analysis

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.
