Short hospital stays after laparoscopic gastric surgery under an Enhanced Recovery After Surgery (ERAS) pathway: experience at a single center.

SummaryIntroductionRecently, first reports on benefits from Enhanced Recovery After Surgery (ERAS) pathway in patients undergoing gastric surgery have appeared. It seems that maximal reduction of unfavorable surgery-induced trauma in patients with gastric malignancy via ERAS protocol combined with minimally invasive techniques can improve outcomes.ObjectiveThe aim of this study was to determine the influence of laparoscopic surgery and ERAS protocol in oncological gastric surgery on early outcomes.Materials and methodsProspective analysis involved 28 patients (18 female and 10 male) with gastric malignancy who underwent laparoscopic gastric resection between 2009 and 2013. Gastric tumors (gastrointestinal stromal tumors or adenocarcinoma) were the indication for the surgery. A total of 17 patients underwent laparoscopic local excision, and 11 patients with adenocarcinoma or multiple neuroendocrine tumors underwent laparoscopic D2 total gastrectomy. Perioperative care was based on ERAS principles. Length of hospital stay, postoperative course, perioperative complications, and readmission rates were analyzed.ResultsThere was one conversion in the gastrectomy group. All patients were mobilized on the day of surgery. Oral fluids were introduced on day 0 and were well tolerated. Full hospital diet was started on day 2 in all patients, but was well tolerated in only 18 of them. One postoperative complication requiring reoperation was noted. The length of stay after gastrectomy and gastric wedge resection was 4.6 (2–6) and 3.3 (2–6) days, respectively. No readmissions were noted in the entire group.ConclusionsThe implementation of ERAS protocol to clinical practice in combination with laparoscopy in patients with gastric tumors can result in improved postoperative care quality, shortening of hospital stay, and quicker return to normal activity.

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.

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

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.

Enhanced recovery after colorectal surgery in elderly patients

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.

Adrenal incidentalomas: should we operate on small tumors in the era of laparoscopy?

Tumor size smaller than 4 cm as an indication for surgical treatment of incidentaloma is still a subject of discussion. Our aim was the estimation of the incidence of malignancy and analysis of treatment outcomes in patients with incidentaloma smaller than 4 cm in comparison to bigger lesions. 132 patients who underwent laparoscopic adrenalectomy for nonsecreting tumors were divided into two groups: group 1 (55 pts., size < = 40 mm) and group 2 (77 pts., size > 40 mm). Operation parameters and histopathological results were analyzed. No differences in group characteristics, mean operation time, and estimated blood loss were noted. Complications in groups 1 and 2 occurred in 3.6% and 5.2% of patients, respectively (P = 0.67). Malignancy in groups 1 and 2 was present in 1 and 6 patients, respectively (P = 0.13). Potentially malignant lesions were identified in 4 patients in group 1 and 4 patients in group 2 (P = 0.39). The results do not allow for straightforward recommendations for surgical treatment of smaller adrenal tumors. The safety of laparoscopy and minimal, but impossible to omit, risk of malignancy support decisions for surgery. On the other hand, the risk of malignancy in smaller adrenal tumors is lower than surgical complications, which provides an important argument against surgery.

Laparoscopic adrenalectomy by the lateral transperitoneal approach in patients with a history of previous abdominal surgery

Introduction Even the half of patients undergoing laparoscopic adrenalectomy has history of previous abdominal surgeries. However, it is still uncertain if this fact has an impact on the operation itself as well as the postoperative course. Aim To analyze the effects of previous abdominal surgery on surgical outcomes in adrenal tumor patients subjected to laparoscopic adrenalectomy. Material and methods This study included 268 patients with adrenal gland tumors operated on by means of laparoscopic lateral transperitoneal adrenalectomy: 1) previously subjected to at least one abdominal surgery (group A, n = 101), or 2) with no history of previous abdominal operations (group B, n = 167). Results Groups A and B did not differ in terms of tumor size (p = 0.132), mean operation time (p = 0.456), mean intraoperative blood loss (p = 0.754), or perioperative complication rate (p = 0.833). Dissection of intraperitoneal adhesions was considered difficult in 32 patients from group A (31.6%) and 8 subjects from group B (4.7%, p < 0.001). Conversion was required in three subjects from group A (2.9%) and 3 patients from group B (1.8%, p = 0.529). Conclusions Previous abdominal surgery does not constitute a contraindication to laparoscopic transperitoneal adrenalectomy.

Laparoscopic Gastrectomy with Enhanced Recovery After Surgery Protocol: Single-Center Experience

Background Surgery remains the mainstay of gastric cancer treatment. It is, however, associated with a relatively high risk of perioperative complications. The use of laparoscopy and the Enhanced Recovery After Surgery (ERAS) protocol allows clinicians to limit surgically induced trauma, thus improving recovery and reducing the number of complications. The aim of the study is to present clinical outcomes of patients with gastric cancer undergoing laparoscopic gastrectomy combined with the ERAS protocol. Material/Methods Fifty-three (21 female/32 male) patients who underwent elective laparoscopic total gastrectomy due to cancer were prospectively analyzed. Demographic and surgical parameters were assessed, as well as the compliance with ERAS protocol elements, length of hospital stay, number of complications, and readmissions. Results Mean operative time was 296.4±98.9 min, and mean blood loss was 293.3±213.8 mL. In 3 (5.7%) cases, conversion was required. Median length of hospital stay was 5 days. Compliance with ERAS protocol was 79.6±14.5%. Thirty (56.6%) patients tolerated an early oral diet well within 24 h postoperatively; in 48 (90.6%) patients, mobilization in the first 24 hours was successful. In 17 (32.1%) patients, postoperative complications occurred, with 7 of them (13.2%) being serious (Clavien-Dindo 3-5). The 30-day readmission rate was 9.4%. Conclusions The combination of laparoscopy and the ERAS protocol in patients with gastric cancer is feasible and allows achieving good clinical outcomes.

Changes in levels of selected incretins and appetite-controlling hormones following surgical treatment for morbid obesity

Introduction The hormonal brain-gut axis is a crucial element in appetite control and the response to surgical treatment for super obesity. However, mechanisms underlying the metabolic response to surgical treatment for morbid obesity are still not clearly specified. Aim To evaluate and compare the effects of surgical treatment for super obesity by laparoscopic sleeve gastrectomy (LSG) and by laparoscopic Roux-en-Y gastric bypass (LRYGB) on selected incretins and appetite-controlling hormones. Material and methods Thirty-five patients were enrolled in a prospective study. Laparoscopic sleeve gastrectomy was performed in 45.8% of patients, and LRYGB in the remaining 54.2% of patients. Before the procedure fasting blood serum was collected from patients and preserved, to determine levels of selected incretins and brain-gut hormones: glucagon-like peptide 1 (GLP-1), peptide YY (PYY), leptin, and ghrelin. Results Twenty-eight patients came to a follow-up visit 12 months after the surgery. In these patients selected parameters were determined again. The percentage weight loss was 58.8%. The ghrelin levels had decreased, and no statistically significant difference was observed between the two procedures. After both surgical procedures a statistically significant reduction in the leptin level was also observed. Peptide YY levels statistically significantly increased in the whole studied group. The GLP-1 level increased after the surgical procedure. However, the observed change was not statistically significant. Conclusions Both treatment methods result in modification of secretion patterns for selected gastrointestinal hormones, and this was considered to be a beneficial effect of bariatric treatment. The laparoscopic sleeve gastrectomy, being a procedure resulting in a metabolic response, seems to be an equally effective method for treatment of super obesity and comorbidities as the laparoscopic gastric bypass.

Prevention of early infective complications after laparoscopic splenectomy with the Garamycin sponge

Introduction Surgical site infection (SSI) appear to be more frequent in splenectomized patients than might be expected and its incidence can be explained neither by the extent of surgery nor by the risk of bacterial contamination of the operating field. Aim Evaluation the local antibiotic prophylaxis using a gentamicin surgical implant in order to reduce SSI, particularly subphrenic abscesses. Material and methods We conducted a prospective, randomized study of two groups of patients undergoing laparoscopic splenectomy who were considered at high risk of infective complications: patients with idiopathic thrombocytopenic purpura (ITP) pre-treated chronically with systemic steroids and patients with non-Hodgkin lymphoma (NHL). Out of 98 laparoscopic splenectomies performed during the study period, 40 patients with ITP and 20 with NHL met the inclusion criteria and were enrolled in the study. In 20 randomly selected patients with ITP and 10 with NHL, a gentamicin-collagen implant was left in the splenic bed. Results Infective complications occurred in 4 (6.67%) among 60 patients from the entire study group; 2 in patients with ITP and a gentamicin implant who developed fever of unknown cause which resolved after systemic antibiotics, and 2 in patients with NHL and gentamicin prophylaxis who developed a subphrenic abscess. In all patients operated on without a gentamicin implant, the postoperative course was uncomplicated. Conclusions Gentamicin surgical implants not only fail to reduce the risk of subphrenic abscesses in splenectomized patients, but may contribute to the increase in its incidence, which puts into question the possible benefits of this form of prophylaxis.
