RESUMO
BACKGROUND: Patients with peritoneal metastases of gastric cancer have a poor prognosis and median survival of 7 months. This study compared treatment options and outcomes based on the Peritoneal Cancer Index (PCI). METHODS: This retrospective analysis included patients with gastric cancer treated between August 2008 and December 2017 with synchronous peritoneal metastases only diagnosed by laparoscopy. The three treatments were as follows: (1) cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in combination with pre- and postoperative systemic chemotherapy (n = 58), (2) laparotomy/laparoscopy without CRS, but HIPEC in combination with pre- and postoperative systemic chemotherapy (n = 11), and (3) systemic chemotherapy only (n = 19). RESULTS: A total of 88 patients aged 54.6 ± 10.9 years with mean PCI of 14.3 ± 11.3 were included. The PCI was significantly lower in group 1 (8.3 ± 5.7) than in group 2 (23.9 ± 11.1, p < 0.001) and group 3 (27.3 ± 9.3, p < 0.001). Mean time from diagnosis to laparoscopy was 5.2 ± 2.9 months. The median overall survival was 9.8 ± 0.7 for group 1, 6.3 ± 3.0 for group 2 and 4.9 ± 1.9 months for group 3 (p < 0.001). Predictors for deteriorated overall patient survival included > 4 cycles of preoperative chemotherapy (HR 4.49, p < 0.001), lymph-node metastasis (HR 3.53, p = 0.005), PCI ≥ 12 (HR 2.11, p = 0.036), and incompleteness of cytoreduction (HR 4.30, p = 0.001) in patients treated with CRS and HIPEC. CONCLUSION: CRS and HIPEC showed convincing results in selected patients with PCI < 12 and complete cytoreduction. Prolonged duration (> 4 cycles) of preoperative intravenous chemotherapy reduced patient survival in patients suitable for CRS and HIPEC.

AIM: Extraperitoneal rectal resection combined with complete peritonectomy of the pelvis in patients with peritoneal metastases is associated with a high rate of morbidity and mortality due to anastomotic leakage (AL). Therefore, many centers tend to perform loop ileostomy to reduce the clinical impact of AL. The aim of this study was to analyze the need for protective stoma creation in this patient group to avoid major complications and mortality in the case of AL. METHOD: We analyzed 53 patients who underwent extraperitoneal rectal resection from 409 consecutive patients treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) at our department between January 1997 and December 2016. RESULTS: Mean age of the patients was 56.7 (SD 12.2) years and the mean Peritoneal Cancer Index was 24.6 (SD 12.0). Complete cytoreduction was achieved in 33 patients (62.3%). Six patients received an ileostomy or a colostomy, 5 of 6 with permanent intention. One patient (2.1%) developed AL postoperatively. Overall, 21 patients (39.6%) developed surgical complications, while 41 (77.3%) developed medical complications. The mortality rate was 7.5% (n = 4). In total, 26 patients (49.1%) developed Clavien-Dindo class-III/IV complications. CONCLUSIONS: These results demonstrate the safety of colorectal anastomosis in combination with HIPEC in the absence of loop ileostomy. Loop ileostomy may be omitted for patients with low risk for AL in experienced centers with adequate post-operative care, possibilities for post-operative assessment and radiological intervention to avoid stoma related complications and increase the quality of life of patients with peritoneal metastases.

RESUMO
OBJECTIVES: This study investigated the correlation between the peritoneal carcinomatosis index (PCI) and patient outcome depending on the tumour type. BACKGROUND: Peritoneal surface malignancy (PSM) treatment depends on tumour type. Mucinous PSM (m-PSM) is associated with a better prognosis than non-mucinous PSM (nm-PSM). The PCI's predictive ability has not yet been evaluated. METHODS: We analysed 123 patients with PSM treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) between 2008 and 2015. The m-PSM group (n = 75) included patients with appendiceal cancer (n = 15), colorectal cancer (n = 21), or low-grade appendiceal mucinous neoplasm (n = 39); the nm-PSM group (n = 48) included patients with gastric (n = 18) or colorectal (n = 30) cancer. The PCI's predictive ability was evaluated by multiple Cox-proportional hazard regression analysis and Kaplan-Meier curves. RESULTS: The 5-year survival and PCI were higher in m-PSM patients (67.0%; 20.5 ± 12.1) than in nm-PSM patients (32.6%; p = 0.013; 8.9 ± 6.0; p < 0.001). Colorectal nm-PSM patients with PCI ≥16 had a worse 2-year survival (25.0%) vs. patients with PCI <16 (79.1%; log rank = 0.009), but no significant effect was observed in patients with m-PSM (66.7% vs. 68.1%; p = 0.935). Underlying disease (HR 5.666-16.240), BMI (HR 1.109), and PCI (HR 1.068) significantly influenced overall survival in all patients. CONCLUSIONS: PCI is prognostic in nm-PSM, but not in m-PSM. CRS and HIPEC may benefit not only patients with low PCI, but also those with high PCI and m-PSM.

BACKGROUND: Lymphatic fistulas are common complications after lymph node dissections in melanoma patients. We investigated whether drain management could improve the patient's outcome. METHODS: Patients who underwent axillary or inguinal lymph node dissection (RALND or RILND) for malignant melanoma were recorded in a prospective database. Two different methods of drain management were compared. Either the drain was removed no later than the eighth postoperative day (period I, 2003-2007) or it was left in place until fluid flow was below 50 ml in 24 h for two consecutive days (period II, 2008-2011). The main outcome criterion was the incidence of seroma punctures after drain removal. RESULTS: 374 patients were analysed. The incidence of seroma punctures significantly decreased in period II. The number of patients with elevated lymphatic secretions rose by 41.3% (RALND) and 38.1% (RILND). With the exception of lymphatic fistulas, we observed significantly more local complications with need for treatment in period I (n = 104, 52%) than in period II (n = 31, 18%). In period II, the hospital stays after both procedures were significantly reduced. CONCLUSIONS: We conclude that quantity-guided drain management leads to a prolonged interval of drainage but is associated with a lower incidence of seroma formation and shorter hospital stay.

OBJECTIVE: To investigate the course of health-related quality of life (HQL) over time in patients with peritoneal carcinomatosis (PC) after complete cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: Prospective, single-center, nonrandomized cohort study using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire. RESULTS: Ninety patients who underwent CRS and HIPEC for PC in our institution were enrolled in the study. Mean age was 56 years (range 27-77 years) (61% female). Primary tumor was colorectal in 21%, ovarian in 19%, pseudomyxoma peritonei in 16%, an appendix tumor in 16%, gastric cancer in 10%, and peritoneal mesothelioma in 13% of cases. Mean peritoneal carcinomatosis index was 22 (range 2-39). Mean global health status score was 69±25 preoperatively and 55±20, 66±22, 66±23, 71±23, and 78±21 at months 1, 6, 12, 24, and 36, respectively. Physical and role function recovered significantly at 6 months and were close to baseline at the 24-month measurement. Emotional function starting from a low baseline recovered to baseline by month 12. Cognitive and social function had slow recovery on follow-up. Fatigue, diarrhea, dyspnea, and sleep disturbance were symptoms persistent at 6-month follow-up, improving later on in survivors. CONCLUSIONS: Survivors after CRS and HIPEC have postoperative quality of life similar to preoperatively, with most of the reduced elements recovering after 6-12 months. We conclude that reduced quality of life of patients after CRS and HIPEC should not be used as an argument to deny surgical therapy to these patients.

PURPOSE: Although complicated sigmoid diverticulitis is the most common reason for laparoscopic sigmoidectomy, the level of evidence for preference of the laparoscopic approach is low. METHODS: A multicenter, randomized clinical trial comparing laparoscopic and open sigmoidectomy for diverticulitis was conducted to evaluate the short- and mid-term outcome after both techniques. Data were assessed from randomized patients and from patients who refused randomization. Results of the here presented interim analysis describe the difficulties in randomization leading to abortion of recruitment. RESULTS: 149 patients were enrolled in the randomized trial within 36 months until the interim analysis. A further 294 nonrandomized patients who preferred one of both surgical approaches were assessed. Several differences between these groups were apparent including simple epidemiological characteristics such as age (65 vs. 60 years, p < 0.001), gender (65% vs. 55% female, p = 0.05), BMI (27 vs. 26 kg/m(2), p = 0.01), and ASA class < III (72% vs. 87%, p < 0.001). CONCLUSION: The majority of eligible patients refused a random allocation. A widespread presumption of the advantages of laparoscopic surgery was probably the main reason for refusal. Patients participating in randomization did not reflect the general population in recruiting hospitals. Future trials comparing minimal invasive procedures should be conducted before presumptions concerning the outcome are widespread in the general population.

PURPOSE: In the recent past, access to the peritoneal cavity has involved primarily 'natural orifice transluminal' and 'single-port access' techniques, which are based on laparoscopy. The most frequently performed procedure using these new developments is cholecystectomy. Few studies compare more than one 'new' method with the 'golden standard' of laparoscopic cholecystectomy. Here we present the results of the first prospective observational study comparing standard laparoscopic cholecystectomy with single-port cholecystectomy as well as transvaginal-hybrid cholecystectomy. METHODS: Fifty-one patients were included in a prospective observational study (20 four-trocar laparoscopic, 15 transvaginal-hybrid, 16 single-port cholecystectomies). Endpoints of the study were operative time, length of hospital stay and postoperative level of pain (numeric analogue score, while coughing). Conversion rates and complications are reported as well. RESULTS: Median operating times did not differ among all three access methods [55 (35-135) min vs. 65 (35-95) min vs. 68 (35-98) min]. Hospital stay was significantly shorter in the transvaginal-hybrid group [3 (3-12) days] and in the single-port group [3 (1-9) days], compared to the four-trocar laparoscopic group [4 (2-17) days]. Pain score was significantly diminished in the transvaginal-hybrid group during the early postoperative course. CONCLUSIONS: Concerning the length of hospital stay, transvaginal-hybrid cholecystectomy and single-port cholecystectomy appear to be superior to 'conventional' laparoscopic cholecystectomy. Additionally, transvaginal-hybrid access is associated with significantly less pain in the early postoperative course.

BACKGROUND: To optimize postoperative pain therapy after a radical inguinal/iliacal lymph node dissection (RILND), we investigated the influence of a continuous application of a local anaesthetic via a subfascial wound catheter in the abdominal wall in addition to a standardized systemic analgesia. MATERIALS AND METHODS: Between July 2007 and December 2009, 50 patients with stage III/IV of melanoma disease received, in an observational study, a systemic analgesic therapy. Of these patients, 30 were additionally treated with a subfascial catheter. Main outcome criterion was the pain under mobilisation at the first postoperative morning registered via a visual analogue score. Minor criteria were the analgesic requirement, the specific (surgical) complications and the day of discharge. RESULTS: Patients treated with the subfascial catheter had significant less pain at the first postoperative morning in rest (p = 0.02) and after mobilisation (p = 0.03) without increased morbidity (p = 0.45). Less patients of the treatment group needed a supplementary analgesic medication (p = 0.01) and were able to leave hospital earlier than patients of the control group (p = 0.01). CONCLUSIONS: A subfascially placed pain catheter enhances postoperative pain therapy after RILND.

PURPOSE: Elective laparoscopic sigmoid resection (LSR) for symptomatic diverticular disease is supposed to have significant short-term advantages compared to open surgery (open sigmoid resection (OSR)). This opinion is rather based on inferences from trials on colonic resections for malignant diseases or minor laparoscopic surgery. This randomized controlled trial was conducted to compare quality of life as well as morbidity and clinical outcome after LSR vs. OSR following a midterm follow-up period. METHODS: Patients presenting with a symptomatic sigmoid diverticular disease stage II/III (Stock/Hansen) were randomly allocated to LSR or OSR in a prospective multicenter trial. Endpoints included the quality of life assessed with a standardized questionnaire, postoperative mortality, and complications within the follow-up of 12 months after operation. RESULTS: A total of 143 patients randomized between 2005 and 2008 in 12 centers could be analyzed. The recruitment was aborted for nonachievement of the planned sample size. Seventy-five patients were allocated to LSR, and 68 received OSR. Nine operations were converted to OSR (9%) and analyzed as intention to treat. Groups were comparable for age, gender, body mass index, comorbidity, and indication for surgery. Operation time was longer for LSR (p < 0.001). Quality of life did not differ between LSR and OSR, either during the early postoperative course or after 12 months (p = 0.172). Also, mortality and morbidity, including subgroups of major and minor morbidity, were compared. CONCLUSION: LSR was not superior to OSR regarding postoperative quality of life and incidence of complications in this trial.

PURPOSE: Surgical cytoreduction of peritoneal surface malignancy of colorectal origin in combination with hyperthermic intraoperative peritoneal chemotherapy (HIPEC) has become an established treatment approach. Only a few of animal models for scientific research on various therapeutic strategies have been described yet. The feasibility of an established rat model with a peritoneal surface malignancy from colorectal origin for treatment investigation should be examined in this study. METHODS: Peritoneal surface malignancy of colonic origin was induced in 90 male BD IX rats. Animals were randomised into six groups (15 animals per one control and five treatment groups). One treatment group underwent only surgical debulking. The animals of the other four treatment groups received additional interventions: hyperthermic intraperitoneal chemotherapy with mitomycin or gemcitabine, photodynamic therapy or taurolidine lavage. Twenty-one days after treatment, the intraperitoneal status was investigated. Tumour weight, count of tumour nodules and experimental Peritoneal Carcinosis Index (ePCI) were detected. RESULTS: Extended surgical cytoreduction and additional treatments including HIPEC were feasible in this rat model. All treatment groups had a significant lower tumour weight, account of tumour nodes and ePCI if compared with the control group. Comparing the additional therapies only HIPEC with mitomycin lead to relevant tumour reduction after surgery. CONCLUSION: This rat model is suitable for research on the multimodal treatment of peritoneal malignancies. A persisting cytoreductive effect of surgical tumour debulking could be proven. Only additional HIPEC therapy with mitomycin showed a significant tumour reduction. This animal model provides the opportunity to investigate different therapeutic strategies.

Postoperative pain is one of the major problems caused by the operative trauma. We recorded the postoperative pain of patients who underwent a radical axillary lymph node dissection (RALND) to evaluate the quality of our standardized perioperative pain management program and the influence of surgical complications. Between August 2003 and December 2007, we registered the postoperative level of pain of 111 patients who underwent a therapeutic RALND, using a visual analog scale (VAS). Patients received standardized perioperative pain therapy according to level I of the World Health Organization (WHO) ladder of pain. We registered a VAS score of 10 in patients at rest during the first 3 postoperative days, but after mobilization of the arm, patients had significantly more pain (P < 0.0001). Patients with a postoperative surgical complication needed significantly more central analgesia to reach the same level of pain (P = 0.04) as patients without complication. Level I of the WHO ladder of pain is not enough for patients after an RALND. Patients with a postoperative complication do have increased pain, and use of only peripheral analgesia is insufficient.

PURPOSE: We performed an experimental study in a rabbit model to investigate the effects of a selective Cox-2 inhibitor (Valdecoxib) on anastomotic healing following large bowel resection after 1 week. MATERIALS AND METHODS: Eighty New Zealand white rabbits were randomized into four groups and underwent a colon resection with end-to-end anastomosis. Group 1 (n = 20) was treated with Valdecoxib, group 2 with Metamizole (Novalgin), group 3 with Resveratrol (specific Cox-1 inhibitor), or a placebo vehicle with similar volume (group 4). Anastomotic healing was tested at the seventh postoperative day by measurement of the bursting pressure in vitro. Immunohistochemical staining of the anastomotic site was performed with polyclonal antibodies (CD31). RESULTS: There were no significant differences in anastomotic dehiscence, bursting pressure, or vessel density between the treatment and control groups. CONCLUSION: The application of Valdecoxib does not influence anastomotic healing or new vessel formation in the anastomotic region following large bowel resection.

BACKGROUND: In the treatment of gastroesophageal reflux disease (GERD), anterior fundoplications are emphasized for their lower risk of complications compared to the posterior approach. AIM: The aim of this study was to evaluate the long-term results of laparoscopic anterior 180 degrees fundoplication in consideration of quality of life and reflux control. METHODS: One hundred and twenty-four patients suffering from GERD underwent laparoscopic anterior 180 degrees fundoplication and were enrolled in this observational trial. After a mean follow-up of 52 months, 95 patients remained in the study. The success of reflux control and the quality of life were assessed using standardized questionnaires (Gastrointestinal Quality of Life Index and Reflux Activity Index scores). RESULTS: Seventy-one patients (75%) reported that the operation was fully successful. Three patients (2%) had no clear opinion, while 21 patients (22%) reported they were poorly or not satisfied. Statistical evaluation of the questionnaires showed a clear difference (p < 0.001) in quality of life scores of patients who needed a continuous postoperative treatment for GERD compared to completely satisfied patients. CONCLUSION: The laparoscopic anterior 180 degrees partial fundoplication for the treatment of GERD can result in satisfying reflux control in long-term outcome, but the postoperative quality of life is severely affected by the success of the treatment.

BACKGROUND AND OBJECTIVE: The results of studies validating the assessment of cardiac output by pulmonary artery thermodilution and a modified algorithm using thoracic bioimpedance/electrical velocimetry in patients undergoing elective cardiac surgery are conflicting. The present observational study was designed to detect whether electrical velocimetry measurements are comparable to transthoracic thermodilution in septic patients after major general surgery. METHODS: Cardiac output was assessed simultaneously by thoracic bioimpedance measurement/electrical velocimetry and transthoracic thermodilution technique (PiCCO) in 30 patients with severe systemic inflammatory response syndrome or sepsis with haemodynamic instability being treated in the surgical intensive care unit of an university hospital. RESULTS: Thirty simultaneous measurements were taken with both methods. The Bland-Altman analysis of agreement revealed a bias of -0.3 l min(-1) with a precision of +/-1.9 l min(-1) and wide limits of agreement (-4.1-3.5 l min(-1)). The percentage error was 54%. CONCLUSION: There was poor agreement between the values of cardiac output estimation by transthoracic thermodilution and those by electrical velocimetry. Electrical velocimetry could not replace invasive monitoring in this trial.

BACKGROUND: Primary peritoneal serous papillary carcinoma is a rare malignant epithelial tumor which was first described in 1959. Peritoneal serous papillary carcinoma arises from the peritoneal epithelium and originates from a single or multicentric focus of the peritoneum involving the peritoneum of the abdomen and pelvis. The involvement of retroperitoneal lymph nodes occurs in 64% of the patients diagnosed with this malignancy. So far, there is no report about inguinal lymph node metastasis in this disease. CASE REPORT: We present a rare case of a 63-year-old female patient who developed singular inguinal lymph node metastasis 1 year after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy due to peritoneal serous papillary carcinoma. The lymph node metastasis was found by computed tomography (CT) scan and was resected and histologically confirmed. The postoperative course was uneventful, and the patient was discharged on postoperative day 1. The last CT scan 24 months after initial cytoreduction and 12 months after lymph node resection showed no further tumor recurrence. CONCLUSION: This case report should raise the awareness of potentially unexpected presentation of extraperitoneal metastasis and highlights the importance of patient follow-up including clinical examination and CT scans of thorax/abdomen/pelvis following a systematic schedule.
RESUMO
OBJECTIVES: Treatment options for patients with gastrointestinal cancer and oligometastastic disease remain the domain of the medical oncologist. However, in selected cases, attempts to remove or destroy the tumor burden seem appropriate. BACKGROUND DATA: During the last decade, the treatment of localized and isolated tumor nodules, such as lung, liver or peritoneal metastasis, has changed. Previously, these patients with metastatic disease only received palliative chemotherapy. Combined treatment approaches and new techniques demonstrate that additional surgery to destroy or remove the metastases seem to be of major benefit to patients. METHODS: The recently published important literature regarding peritoneal metastases and oligometastases in gastrointestinal cancer was analyzed. RESULTS: The most important factor in the treatment of peritoneal metastases and in cytoreductive surgery is patient selection. Resection of peritoneal metastases should be considered. Hyperthermic intraperitoneal chemotherapy is feasible. However, further results of randomized trials are necessary. Several randomized trials are on the way and will be available in 1-2 years. Systemic chemotherapy alone as an adequate management plan for all sites of metastatic disease is not compatible with a high standard of care. Formulating an optimal plan combining re-operative surgery with regional plus systemic chemotherapy is a necessary task of the multidisciplinary team. CONCLUSIONS: In oligometastastic disease of gastrointestinal cancer origin, the selection process is the most important factor for survival. Further studies are needed to determine optimal treatment options.
RESUMO
INTRODUCTION: In selected cases, cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is an established treatment for patients suffering from peritoneal metastases from colorectal, ovarian, gastric or appendiceal origin. The effectiveness of this extensive has not been elucidated within other rare diseases by now. METHODS: We conducted a retrospective analysis of patients treated with CRS for peritoneal carcinomatosis during the period between July 2010 and September 2015. Exclusion criteria were adenocarcinomas of the stomach, colon, neoplasms of the appendix, mesothelioma and ovarian cancers. Aim of this study was to examine the feasibility, complication rate and survival of patients with rare diseases. RESULTS: A total of 14 Patients were included: Four rare gynecological tumors, three adenocarcinomas of the small intestine, three retroperitoneal sarcomas, one cholangiocellular carcinoma, one neuroendocrine gastric tumor, one malignant peripheral nerve sheath tumor and one cancer of unknown primary syndrome. In 12 of 14 patients a macroscopically complete tumorresection could be achieved. No patient died during hospitalization. Seven of 14 patients experienced general complication of grade III according to NCI CTCAE V4.0, while two experienced complications of grade IV. Median follow-up and one year overall survival were 15.5 months and 46.8%, respectively. CONCLUSION: For patients with rare tumors, CRS and HIPEC is feasible with an acceptable perioperative morbidity and mortality. To improve knowledge in patient selection and outcome, rare tumors treated with CRS and HIPEC should be documented in central databases (as for example BIG RENAPE, Pierre-Benite, France).
RESUMO
BACKGROUND: The role of telematic surgical approach in gastro-oesophageal reflux disease (GERD) is still unclear. METHODS: The aim of the study is to assess disease specific symptoms and quality of life in patients with GERD treated with either traditional laparoscopic (TL) or robot-assisted fundoplication using the Da Vinci system (DV) in long-term follow-up. RESULTS: Eighty patients underwent a fundoplication in 2003. Four years later all patients were given a standardized questionnaire and 59 (74%) replied. The TL group included 44 patients (18 male/26 female) and the DV group 15 patients (9 male/6 female); the mean operating time was 116 min for the TL group and 207 min for the DV group (p < 0.001). The mean GIQLI score was 106 points for TL and 107 points in the DV (p > 0.05). CONCLUSIONS: Although a safe and feasible procedure, high functional costs of the Da Vinci system and longer operating time prevent this operation from being the standard surgical procedure for GERD.

BACKGROUND: Patients suffering from malignant melanoma often require radical lymph node dissection of the axillary nodal basin. The effects of intraoperative application of fibrin sealant following radical axillary lymph node dissection (RALND) on the incidence of postoperative lymphatic secretion are discussed. To study the effect of intraoperatively applied fibrin sealant following RALND a randomized patient-blinded trial was carried out. METHODS: Fifty-eight patients with axillary lymph node metastases of malignant melanoma underwent therapeutic RALND and were randomized into two groups: 29 patients received 2 cc of fibrin glue intraoperatively and 29 patients were only irrigated with 0.9% saline. The amount of drainage was recorded every 24 h. The main outcome criterion was the duration of drain placement in the wound. Minor criteria were the total amount of fluid and the length of hospital stay. Statistical analysis was performed using Spearman's log-rank correlation and paired t-test. RESULTS: There was no significant difference between the nonfibrin group 5 days (range = 3.6-5.7 days) and the fibrin group 5 days (range = 4.1-8.5 days) (p = 0.701). The total amount of fluid for the nonfibrin group (410 cc, range = 362-727 cc) and that for the fibrin group (503 cc, range = 369-1098 cc) (p = 0.605) and the length of postoperative hospital stay of 6 days (range = 5.4-7) vs. 7 days (range = 5.9-10.7), respectively, were not different between both groups (p = 0.387). CONCLUSION: Considering our study results, we cannot recommend the use of 2 cc of fibrin glue intraoperatively in the prevention of lymphatic secretion in patients undergoing RALND for metastatic melanoma.

BACKGROUND AND AIMS: Hypovolemia after bowel preparation as well as capnoperitoneum (CP) may compromise hemodynamic function during laparoscopic colonic surgery. A fall in arterial pressure after induction of anesthesia is often answered by generous fluid administration, which might impair "fast-track" rehabilitation. Intraoperative assessment of the needed infusion volume is difficult because of a lack of data regarding the volume status in these patients. PATIENTS AND METHODS: Nineteen patients scheduled for laparoscopic colonic surgery after bowel preparation were prospectively monitored using the PULSION COLD Z-021 system and central venous catheter. Intrathoracic blood volume index (ITBVI), mean arterial pressure (MAP), cardiac index (CI), central venous pressure (CVP), and heart rate (HR) were measured after induction of anesthesia (M1), during CP in head-down position with an intraabdominal pressure (IAP) of 20 mmHg (M2) and 12 mmHg (M3). RESULTS: Although MAP (87 mmHg), HR (64 min(-1)), and CVP (8 mmHg) were within normal ranges at the induction of surgery, ITBVI (834 ml m(-2)), and CI (2.66 l m(-2)) were decreased, indicating a relative hypovolemia. CP with 12 mmHg increased ITBVI (p<0.05) and CI (p<0.01), while an IAP of 20 mmHg reduced CI (p<0.05) compared to 12 mmHg (M3). Mean infusion during the measurements was 1,355 ml. CONCLUSION: Combination of CP with 12 mmHg, head-down position, and infusion of 1,500 ml fluids compensated relative hypovolemia during colonic surgery. With conventional monitoring, intravascular volume status might be underestimated after traditional preoperative care.
