Transumbilical laparoscopy for pneumoperitoneum establishment: a comprehensive multicentre evaluation affirming safety, feasibility, and a range of clinical benefits. Front Surg 2024; 11:1390038. [PMID: 38712337 PMCID: PMC11070471 DOI: 10.3389/fsurg.2024.1390038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Accepted: 04/08/2024] [Indexed: 05/08/2024] Open
Abstract
Introduction Transumbilical laparoscopy (TUL) has emerged as a promising technique for establishing pneumoperitoneum in laparoscopic cholecystectomy, offering potential safety, feasibility, and clinical benefits. This retrospective multicentre study aims to evaluate the efficacy and outcomes of TUL in the management of gallbladder diseases. Methods A retrospective analysis was conducted on a cohort of 2,543 patients who underwent TUL between 2011 and 2021 across various medical institutions in Italy. Data collection included demographic, clinical, intraoperative, and postoperative parameters. Standardized protocols were followed for preoperative and postoperative management. The TUL technique involved precise anatomical incision and trocar placement. Results The study demonstrated favorable outcomes associated with TUL, including a low conversion rate to open surgery (0.55%), minimal intraoperative complications (0.16%), and short hospital stays (average 2.4 days). The incidence of incisional hernias was notably low (0.4%). Comparison with existing literature revealed consistent findings and provided unique insights into the advantages of TUL. Discussion Despite limitations, such as the absence of a control group and the retrospective nature of the study, the findings contribute valuable insights to the literature. They inform surgical decision-making and advance patient care in laparoscopic cholecystectomy for gallbladder diseases. Conclusion Transumbilical laparoscopy shows promise as a safe and feasible technique for establishing pneumoperitoneum in laparoscopic cholecystectomy. The study's findings support its clinical benefits, including low conversion rates, minimal complications, and short hospital stays. Further research, including prospective studies with control groups, is warranted to validate these results and optimize patient outcomes.

Abstract
The impact of blood pressure targets and surgical approach (laparoscopic or open) on continuous urinary oxygenation (PuO2), a validated surrogate of renal medullary PO2, during general surgery, is unclear. We aimed to assess the effects of different blood pressure targets and surgical procedures on PuO2. We randomized patients receiving either laparoscopic or open surgery into two mean arterial pressure (MAP) target groups: usual MAP or a high MAP. We measured PuO2 in real-time and analyzed it according to the type of surgery and blood pressure target. The study was retrospectively registered on the 5th of July 2023 (ACTRN12623000726651). We included 43 participants who underwent either laparoscopic (n = 20) or open surgery (n = 23). We found that PuO2 significantly decreased during both laparoscopic and open surgery under a usual blood pressure target (- 51% and - 49%, respectively). However, there was a sharper fall with laparoscopic surgery resulting in a higher PuO2 with open surgery (mean difference: 11 ± 1 mmHg higher; p < 0.001). Targeting a higher MAP resulted in a higher PuO2 over time during laparoscopic surgery (mean difference: 7 ± 1 mmHg, p < 0.001). In contrast, targeting a usual MAP resulted in a higher PuO2 during open surgery (mean difference: 7 ± 1 mmHg, p < 0.001). Surgical approach and intraoperative blood pressure targets significantly impact urinary oxygenation. Further studies with larger sample sizes are needed to confirm these findings and understand their potential clinical implications.Registration number: ACTRN12623000726651; Date of registration: 05/07/2023 (retrospectively registered).

Low-impact laparoscopy in colorectal resection-A multicentric randomised trial comparing low-pressure pneumoperitoneum plus microsurgery versus low-pressure pneumoperitoneum alone: The PAROS II trial. Colorectal Dis 2023; 25:2403-2413.

Abstract
INTRODUCTION Low-pressure pneumoperitoneum (LLP) in laparoscopy colorectal surgery (CS) has resulted in reduced hospital stay and lower analgesic consumption. Microsurgery (MS) in CS is a technique that has a significant impact with respect to postoperative pain. The combination of MS plus LLP, known as low-impact laparoscopy (LIL), has never been applied in CS. Therefore, this trial will assess the efficacy of LLP plus MS versus LLP alone in terms of decreasing postoperative pain 24 h after surgery, without taking opioids. METHOD PAROS II will be a prospective, multicentre, outcome assessor-blinded, randomised controlled phase III clinical trial that compares LLP plus MS versus LLP alone in patients undergoing laparoscopic surgery for colonic or upper rectal cancer or benign pathology. The primary outcome will be the number of patients with postoperative pain 24 h after the surgery, as defined by a visual analogue scale rating ≤3 and without taking opioids. Overall, PAROS II aims to recruit 148 patients for 50% of patients to reach the primary outcome in the LLP plus MS arm, with 80% power and an 5% alpha risk. CONCLUSION The PAROS II trial will be the first phase III trial to investigate the impact of LIL, including LLP plus MS, in laparoscopic CS. The results may improve the postoperative recovery experience and decrease opioid consumption after laparoscopic CS.

Factors associated with successful median arcuate ligament release in an international, multi-institutional cohort. J Vasc Surg 2023; 77:567-577.e2. [PMID: 36306935 DOI: 10.1016/j.jvs.2022.10.022] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 10/12/2022] [Accepted: 10/12/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Prior research on median arcuate ligament syndrome has been limited to institutional case series, making the optimal approach to median arcuate ligament release (MALR) and resulting outcomes unclear. In the present study, we compared the outcomes of different approaches to MALR and determined the predictors of long-term treatment failure. METHODS The Vascular Low Frequency Disease Consortium is an international, multi-institutional research consortium. Data on open, laparoscopic, and robotic MALR performed from 2000 to 2020 were gathered. The primary outcome was treatment failure, defined as no improvement in median arcuate ligament syndrome symptoms after MALR or symptom recurrence between MALR and the last clinical follow-up. RESULTS For 516 patients treated at 24 institutions, open, laparoscopic, and robotic MALR had been performed in 227 (44.0%), 235 (45.5%), and 54 (10.5%) patients, respectively. Perioperative complications (ileus, cardiac, and wound complications; readmissions; unplanned procedures) occurred in 19.2% (open, 30.0%; laparoscopic, 8.9%; robotic, 18.5%; P < .001). The median follow-up was 1.59 years (interquartile range, 0.38-4.35 years). For the 488 patients with follow-up data available, 287 (58.8%) had had full relief, 119 (24.4%) had had partial relief, and 82 (16.8%) had derived no benefit from MALR. The 1- and 3-year freedom from treatment failure for the overall cohort was 63.8% (95% confidence interval [CI], 59.0%-68.3%) and 51.9% (95% CI, 46.1%-57.3%), respectively. The factors associated with an increased hazard of treatment failure on multivariable analysis included robotic MALR (hazard ratio [HR], 1.73; 95% CI, 1.16-2.59; P = .007), a history of gastroparesis (HR, 1.83; 95% CI, 1.09-3.09; P = .023), abdominal cancer (HR, 10.3; 95% CI, 3.06-34.6; P < .001), dysphagia and/or odynophagia (HR, 2.44; 95% CI, 1.27-4.69; P = .008), no relief from a celiac plexus block (HR, 2.18; 95% CI, 1.00-4.72; P = .049), and an increasing number of preoperative pain locations (HR, 1.12 per location; 95% CI, 1.00-1.25; P = .042). The factors associated with a lower hazard included increasing age (HR, 0.99 per increasing year; 95% CI, 0.98-1.0; P = .012) and an increasing number of preoperative diagnostic gastrointestinal studies (HR, 0.84 per study; 95% CI, 0.74-0.96; P = .012) Open and laparoscopic MALR resulted in similar long-term freedom from treatment failure. No radiographic parameters were associated with differences in treatment failure. CONCLUSIONS No difference was found in long-term failure after open vs laparoscopic MALR; however, open release was associated with higher perioperative morbidity. These results support the use of a preoperative celiac plexus block to aid in patient selection. Operative candidates for MALR should be counseled regarding the factors associated with treatment failure and the relatively high overall rate of treatment failure.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:14708. [PMID: 36429426 PMCID: PMC9690127 DOI: 10.3390/ijerph192214708] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Revised: 11/07/2022] [Accepted: 11/08/2022] [Indexed: 06/16/2023]
Abstract
Monitoring core temperature is crucial for maintaining normothermia during general anesthesia. Insertion of a gastric decompression tube (GDT) may be required during laparoscopic surgery. Recently, a newly designed GDT with a thermistor for monitoring esophageal temperature has been introduced. The purpose of the present study was to evaluate the optimal insertion depth of a GDT with a thermistor. Forty-eight patients undergoing elective laparoscopic surgery in the Trendelenburg position were included in the study. The GDT was inserted to a depth of nose-earlobe-xiphoid distance (NEX) + 12 cm and withdrawn sequentially, 2 cm at a time, at 5-min intervals. Temperatures of the GDT thermistor were compared with the core temperature of the tympanic membrane (TM) using Bland and Altman analysis. The correlation between optimal insertion depth of the GDT and anatomical distance (cricoid cartilage to the carina, CCD; carina to the left hemidiaphragm, CLHD) was evaluated, and a mathematical model to predict the optimal insertion depth of the GDT with a thermistor was calculated. Temperatures of TM and GDT thermistor at NEX + 4 cm showed good agreement and strong correlation, but better agreement and stronger correlation were seen at the actual location with the most minor temperature differences. The optimal insertion depth of the GDT was estimated as -15.524 + 0.414 × CCD - 0.145 × CLHD and showed a strong correlation with the actual GDT insertion depth (correlation coefficient 0.797, adjusted R2 = 0.636). The mathematical formula using CCD and CLHD would be helpful in determining the optimal insertion depth of a GDT with a thermistor.

Abstract
BACKGROUND Smoke produced by traditional open surgery (TOS) has long been considered hazardous to medical staff. Compared with TOS, minimally invasive surgery under carbon dioxide pneumoperitoneum is associated with a faster recovery and less wound pain. However, the impact of oxygen-deficient environment on the chemical contents of smoke has not been comprehensively assessed. METHODS This research evaluated the chemical composition and volatile organic compound (TVOC) level in smoke produced by open cholecystectomy (OC) versus laparoscopic cholecystectomy (LC) for gallbladder diseases. Smoke samples were collected and analyzed via gas chromatography-mass spectrometry. Chemical compounds were further grouped according to molecular weight and toxicity. RESULTS Compared with the OC, LC had significantly higher halocarbon and TVOC levels but lower cycloalkene and aldehyde levels. No halocarbons were isolated from OC specimens. When stratified based on molecular weight, LC had a bimodal pattern (i.e., high levels of small-sized [<60 Da] and large-sized [>120 Da] compounds). There was no difference in terms of toxicity types, incidence, and severity associated with detected compounds between two groups. CONCLUSION LC is associated with a higher TVOC level and proportion of low- and high-molecular-weight organic compounds. Further strategies of evacuating these health hazards and preventing smoke leakage through trocars should be considered.

Abstract
This paper reports a case of a 21 year old primigravida at 6 weeks gestation, suffering from important abdominal pain, who was admitted into the medical center with a giant cyst of 28 × 20 cm on her left ovary. A torsion of the ovarian cyst was suspected. Her COVID-19 status was unknown. In view of the emergency of the situation and the COVID-19 pandemic, laparoscopy in spinal anesthesia was performed. The patient remained conscious during the surgical intervention and tolerated it well apart from a slight dyspnea, which was easily eliminated by changing her body position and decreasing the pneumoperitoneum pressure. The ovarian cyst was removed by enlarging the trocar incision. The patient recovered with neither incident nor pregnancy loss. COVID-19-related complications can induce adverse pregnancy outcomes. Under general anesthesia, patients with COVID-19 are at risk of severe pneumonia and of passing their infection to the medical personnel. To avoid such complications in non-specialized centers, laparoscopy should be performed in regional anesthesia. Laparoscopy in spinal anesthesia can be performed safely on pregnant patients by placing them in the proper position, using a low pneumoperitoneum, and monitoring the hemodynamics. During early pregnancy, general anesthesia induces a higher risk of teratogenic effects and of miscarriage.

Abstract
BACKGROUND laparoscopic surgery is mainly performed in general anesthesia. Symptomatic patients infected with COVID-19 needing surgery are however at higher risk for COVID-19 complications in general anesthesia than in regional anesthesia. Even so, Covid transfection is a hazard to medical personnel during the intubation procedure and treatment drugs may be in shortage during a pandemic. Recovery and hospital stay are also shorter after laparoscopy. Laparoscopy performed in regional anesthesia may have several advantages in limiting Covid. METHODS international literature on the risk of COVID-19 complications development was searched. 3 topics concerning laparoscopic surgery were reviewed: (1) Achievements in laparoscopy; (2) Advantages of regional anesthesia compared to general anesthesia; (3) Feasibility to perform laparoscopy in regional anesthesia in COVID-19 pandemic. The authors reviewed abstracts and full-text articles concerning laparoscopic surgery, gynecology, anesthesia and COVID-19. Studies published in PubMed, Embase, Cochrane Library and found in Google Scholar before 1st FEB, 2021 were retrieved and analyzed. RESULTS a total of 83 studies were found, all of them written in English. 17 studies could be found in gynecology and in general surgery about laparoscopy with regional anesthesia. In Covid time only one study compared laparoscopic surgery in general anesthesia to laparotomy and another study laparotomy in general anesthesia to regional anesthesia. Laparoscopy showed no disadvantage compared to laparotomy in Covid pandemic and in another study laparotomy in general anesthesia was associated with higher mortality and more pulmonary complications. Trendelenburg position can be a threat if used by inexperienced personnel and can induce unintended anesthesia of breathing organs. On the other hand Trendelenburg position has advantages for cardiovascular and pulmonary functions. Pneumoperitoneum of low CO2 pressure is well tolerated by patients. CONCLUSIONS elective surgery should be postponed in symptomatic Covid patients. In inevitable emergency surgery intubation anesthesia in COVID-19 pandemic is as far as possible to be avoided. In COVID-19 pandemic, regional anesthesia is the preferred choice. The optimum may be the combination of laparoscopic surgery with regional anesthesia. Reducing the pneumoperitoneum is a good compromise for the comfort of patients and surgeons. A special case is gynecology, which needs to be performed in Trendelenburg position to free pelvic organs.

Abstract
New generation supraglottic airway devices are suitable for airway management in many laparoscopic surgeries. In this study, we evaluated and compared the ventilation parameters of the laryngeal mask airway-supreme (LM-S) and endotracheal tube (ETT) when a neuromuscular blocker (NMB) agent was not used during laparoscopic gynecological surgery. The second outcome was based on the evaluation of the surgical view because it may affect the surgical procedure.This was a randomized study that enrolled 100 patients between 18 and 65 years old with an ASA I-II classification. Patients were divided into 2 groups: Group ETT and Group LM-S. Standard anesthesia and ventilation protocols were administered to patients in each group. Ventilation parameters [airway peak pressure (Ppeak), mean airway pressure (Pmean), total volume, and oropharyngeal leak pressure] were recorded before, after, and during peritoneal insufflation and before desufflation, as well as after the removal of the airway device. Perioperative surgical view quality and the adequacy of the pneumoperitoneum were also recorded.The data of 100 patients were included in the statistical analysis. The Ppeak values in Group ETT were significantly higher in the second minute after airway device insertion. The Ppeak and Pmean values in Group ETT were significantly higher before desufflation and after removal of the airway device. No significant differences were found between the groups in terms of adequacy of the pneumoperitoneum or quality of the surgical view.The results of this study showed that gynecological laparoscopies can be performed without using a NMB. Satisfactory conditions for ventilation and surgery can be achieved while sparing the use of muscle relaxants in both groups despite the Trendelenburg position and the pneumoperitoneum of the patients, which are typical for laparoscopic gynecological surgery. The results are of clinical significance because they show that the use of a muscle relaxant is unnecessary when supraglottic airways are used for these surgical procedures.

Abstract
OBJECTIVES We aimed to compare tympanic membrane temperature changes and the incidence of inadvertent perioperative hypothermia (IPH) in patients undergoing laparoscopic cholecystectomy under general anesthesia in laminar airflow systems (LAS-OR) and conventional turbulent airflow systems (CAS-OR). BACKGROUND Different heating, ventilation, and air-conditioning (HVAC) systems are used in the operating room (OR), such as LAS and CAS. Laminar airflow is directed directly to the patient in LAS-OR. Does laminar airflow in ORs cause faster heat loss by convection? METHODS This is a prospective, randomized study. We divided 200 patients with simple randomization (1:1), as group LAS and group CAS, and took the patients into the LAS-OR or CAS-OR for the operation. Clinical trial number: IRCT20180324039145N3. The tympanic membrane temperatures of patients were measured (°C) before anesthesia induction (T 0) and then every 15 min during surgery (Tn). Changes (Δn) between T 0 and Tn were measured. RESULTS In the first 30 min, there was a temperature decrease of approximately 0.8 °C (1.44 °F) in both groups. Temperature decreases at 45 min were higher in group LAS than in group CAS but not statistically significant, Δ45, respectively, 0.89 (95% confidence interval [CI] [0.77, 1.02]) versus 0.77 (95% CI [0.69, 0.84]; p = .09). IPH occurred in a total of 60.9% (112 of 184) of patients in the entire surgical evaluation period in group LAS and group CAS (58.9% vs. 62.8%, p = . 59). CONCLUSIONS IPH is seen frequently in both HVAC systems. Clinically, the advantage of HVAC systems relative to each other has not been demonstrated during laparoscopic cholecystectomy.

Abstract
Background: Supraglottic airway devices have increasingly been used as the airway technique of choice in laparoscopic surgeries. This study compared the efficacy and safety of the Baska Mask with endotracheal tube (ETT) in patients undergoing elective laparoscopic cholecystectomy.Research design and methods: This single-center, prospective, randomized controlled trial recruited 60 patients aged 18-75 years with American Society of Anesthesiologists' classifications I to III. The time taken to achieve effective airway, number of attempts, ease of insertion, ventilation parameters, hemodynamics data, and pharyngolaryngeal complications were recorded.Results: The time taken to achieve effective airway was shorter for the Baska group (26.6 ± 4.7 vs. 47.2 ± 11.8 s; p < 0.001), although the first-time insertion success rate was ≥90% for both groups. The ETT group experienced more pharyngolaryngeal complications, including cough, trauma, spasm, dysphonia, and sore throat, during device insertion and removal and had higher systolic and diastolic blood pressures during intubation (p = 0.001). The Baska Mask achieved significantly lower peak airway pressure (p = 0.024) with stable oropharyngeal leak pressure ≥33 cmH2O throughout the surgery.Conclusions: The Baska Mask is a suitable alternative to endotracheal intubation in selected patients undergoing laparoscopic cholecystectomy, with shorter insertion times, fewer perioperative complications, and improved ventilatory performance and hemodynamic response.Trial registration: The trial is registered at ClinicalTrials.gov (NCT03045835), 8 February 2017.

Abstract
Minimally invasive robotic-assisted surgeries have been increasingly used as a first-line of treatment for patients undergoing oncologic surgeries. In-situ tissue identification is critical to guide tissue resection and assist decision-making. Traditional intraoperative histopathologic analysis of frozen tissue sections can be time-consuming and present logistical challenges which interrupt surgical workflows. We report the development and implementation of a laparoscopic, drop-in version of the MasSpec Pen device integrated into the da Vinci Xi Surgical system for in vivo tissue analysis in a robotic-assisted porcine surgery. We evaluated the performance of the drop-in MasSpec Pen during surgery by introducing the device into the animal upper gastrointestinal system and performing in vivo analyses of the stomach and liver, including charred and bloody tissues after electrocauterization. The molecular profiles obtained included ions tentatively identified as metabolites and lipids typically observed with MasSpec Pen analysis, without causing observable tissue damage. Statistical classifiers built to distinguish porcine liver and stomach tissues using the in vivo data yielded an overall tissue identification accuracy of 98% (n = 53 analyses). The results provide evidence that the drop-in MasSpec Pen developed can be used to acquire mass spectra in vivo during a robotic-assisted surgery and might be used as an in vivo tissue assessment tool to help guide surgical resections and streamline surgical workflows.

Abstract
Surgical smoke generated by use of electrosurgical units (ESUs), lasers, and ultrasonic scalpels constitutes a physical, chemical, and biological hazard for anesthesia personnel. Inhalation of particulate matter with inflammatory consequences, pulmonary injury from products of tissue pyrolysis, exposure to mutagens and carcinogens, and the transmission of human papillomavirus (HPV) and possibly other pathogens represent a spectrum of adverse effects associated with the occupational exposure to surgical plume. While adequate operating room ventilation and use of high filtration-efficiency masks offer some protection from these conditions, the most effective method of safeguarding against surgical smoke involves its removal with a dedicated smoke evacuation device (SED). Despite the fact that many professional and governmental agencies have endorsed widespread usage of SEDs, anesthesia providers have been largely silent on this subject, with few reports within the field of anesthesiology and perioperative medicine regarding these hazards. SED use is relatively infrequent in most surgeries, and this condition reflects surgeons' reluctance to employ these devices, likely resulting from lack of education and less than optimal technology. Anesthesia societies and academic centers can serve critical roles in advocating employment of SEDs in much the same way that they have supported perioperative smoking cessation.

Abstract
Background Laparoscopy, by its minimally invasive nature, has revolutionized digestive and particularly colorectal surgery by decreasing post-operative pain, morbidity, and length of hospital stay. In this trial, we aim to assess whether low pressure in laparoscopic colonic surgery (7 mm Hg instead of 12 mm Hg) could further reduce pain, analgesic consumption, and morbidity, resulting in a shorter hospital stay. Methods and analysis The PAROS trial is a phase III, double-blind, randomized controlled trial. We aim to recruit 138 patients undergoing laparoscopic colectomy. Participants will be randomly assigned to either a low-pressure group (7 mm Hg) or a standard-pressure group (12 mm Hg). The primary outcome will be a comparison of length of hospital stay between the two groups. Secondary outcomes will compare post-operative pain, consumption of analgesics, morbidity within 30 days, technical and oncological quality of the surgical procedure, time to passage of flatus and stool, and ambulation. All adverse events will be recorded. Analysis will be performed on an intention-to-treat basis. Trial registration This research received the approval from the Committee for the Protection of Persons and was the subject of information to the ANSM. This search is saved in the ID-RCB database under registration number 2018-A03028–47. This research is retrospectively registered January 23, 2019, at http://clinicaltrials.gov/ed under the name “LaPAroscopic Low pRessure cOlorectal Surgery (PAROS)”. This trial is ongoing.

Abstract
The optimal management of patients with ventriculoperitoneal or lumboperitoneal shunts undergoing abdominal or pelvic surgery for unrelated reasons is often unclear due to the paucity of guidelines in this field. In this review, we outline key issues in managing these patients. Specifically, we address issues relating to pre-operative planning, avoidance of shunt-related complications such as infection and malfunction, and specific management of neurological symptoms in the post-operative period. A retrospective study was carried out analysing correspondence between general surgeons and a specialist hydrocephalus unit over a 4-year period relating to management of patients with ventriculoperitoneal and lumboperitoneal shunts undergoing abdominal or pelvic surgery. A literature review was carried out to identify available evidence in this field. 30 queries from general surgeons were identified comprising 12 main themes. 16 relevant publications were identified. We summarised these to answer these queries. The management of shunted patients may present challenges and uncertainties in an abdominal or pelvic surgery setting. This paper provides guidelines and clarity in this field by discussing and summarising reported data in the literature.

Abstract
INTRODUCTION Randomized trials demonstrated oncologic safety and short-term benefits of laparoscopy. We investigated if the benefit of laparoscopy on short-term outcomes is greater for older adults compared with younger adults. METHODS We identified all older (≥70 years old) and younger (<70) adults with primary sigmoid and rectal cancer treated with resection between 2002 and 2018 from an institutional database. We compared 30-day postoperative outcomes using multivariable logistic regression with an interaction term between age group and surgical approach. Primary outcomes were death, major (Clavien-Dindo III-IV) and minor (Clavien-Dindo I-II) complications, and wound complications. RESULTS We included 792 patients, 293 (37%) older and 499 (63%) younger. Use of laparoscopy was similar between age groups: 120/293 (41%) older, 204/499 (41%) younger (p = .98). All patients had 30-day follow-up. Compared with open resection, minimally-invasive resection was associated with a greater reduction in deaths in older adults than in younger adults (absolute difference in older adults 7.0% less versus 2.1% less in younger adults; adjusted odds ratio [aOR] older 3.01, 95% confidence interval [CI] 1.31-7.33; aOR younger 0.31, 95% CI 0.05-1.24; interaction p = .01). Similarly, minimally-invasive resection was associated with a greater reduction in major complications in older adults than in younger adults (absolute difference in older adults 6.4% less versus 2.4% less in younger adults; aOR older 1.91, 95% CI 1.07-3.41; aOR younger 0.70, 95% CI 0.34-1.38; interaction p = .03). CONCLUSIONS Minimally-invasive compared with open surgery demonstrated a differential benefit on postoperative death and major complications between younger and older adults.

Although several surgical approaches, including the laparoscopic approach, have been reported to date, a standard approach for treating OH has not been established. A 101-year-old woman who presented with constipation and vomiting was admitted to our hospital. CT revealed an incarcerated small bowel within the left obturator foramen, and a diagnosis of left-sided incarcerated OH with small bowel ileus was made. With the patient under general anesthesia, exploratory laparoscopy was performed; we identified an OH with an incarcerated small bowel, which was judged viable after hernia reduction. We repaired the hernia using an anterior preperitoneal approach under laparoscopic assistance and placed a prosthetic mesh over the obturator foramen. The patient recovered with no postoperative complications and was discharged on postoperative day 4. A hybrid laparoscopic and anterior preperitoneal approach is safe and effective for treating an incarcerated OH in an elderly patient.

Abstract
PURPOSE Laparoscopic liver resection is safe, feasible and associated with less blood loss, shorter hospital stays and fewer postoperative complications in the working age patients with malignant liver tumors. However, it is still unclear if the elderly patients with malignant liver tumors would also benefit from that approach as the younger patients. So, the aim of the study was to compare the clinical outcomes of laparoscopic versus open liver resection for malignant liver tumors in elderly patients. MATERIALS AND METHODS Between March 2009 and July 2016, all elderly patients (≥70 years old) who underwent laparoscopic (n = 40) and open (n = 202) liver resection for malignant liver tumors were included. A one to one propensity score matching analysis was performed, based on 6 covariates, to decrease the selection bias. RESULTS There was no significant difference between the laparoscopic and open liver resection groups regarding the patient characteristics and tumor features. The operative time was comparable between both groups (Laparoscopic group 259 min vs Open group 308 min, p = .86), while patients who underwent laparoscopic liver resection had lower intraoperative blood loss (30 ml vs 517 ml, p < .0001), shorter hospital stays (10 days vs 23 days, p < .0001), and less overall morbidity (15% vs 38%, p = .04). The one-, three-, and five-year survival for patients with hepatocellular carcinoma was comparable between both groups (Laparoscopic group 96%, 74%, 47%, vs Open group 94%, 71%, 48%, p = .82), whereas The one-, three-, and five-year recurrence-free survival for patients with hepatocellular carcinoma was significantly higher in the laparoscopic group (88%, 60%, 60% vs 54%, 25%, 19%, p = .019). CONCLUSIONS Laparoscopic approach for minor liver resection in elderly patients is safe and feasible with less blood loss, a shorter hospital stay, less postoperative complications and a better oncological outcome.

Abstract
INTRODUCTION Sustained deep neuromuscular blockade (NMB) during laparoscopic surgery may facilitate optimal surgical conditions. This exploratory study assessed whether deep NMB improves surgical conditions and, in doing so, allows use of lower insufflation pressures during laparoscopic cholecystectomy. We further assessed whether use of low insufflation pressure improves patient pain scores after surgery. METHODS This randomized, controlled, blinded study (NCT01728584) compared use of deep (1-2 post-tetanic-counts) or moderate (train-of-four ratio 10%) NMB, and lower (8 mmHg) or higher (12 mmHg; 'standard') insufflation pressure in a 2 × 2 factorial design. Primary endpoint was surgeon's overall satisfaction with surgical conditions, rated at end of surgery using an 11-point numerical scale. Post-operative pain scores were also evaluated. Data were analyzed using analysis of covariance. RESULTS Of 127 randomized patients, 120 had evaluable data for the primary endpoint. Surgeon's score of overall satisfaction with surgical conditions was significantly higher with deep versus moderate NMB indicated by a least-square mean difference of 1.1 points (95% confidence interval 0.1-2.0; P = 0.026). Furthermore, strong evidence of an effect was observed for standard versus low pressure: least-square mean difference of 3.0 points (95% confidence interval 2.1-4.0; P < 0.001). No significant difference was observed in average pain scores within 24 h post-surgery for low versus standard pressure [0.17 (95% confidence interval -0.67 to +0.33); P = 0.494]. CONCLUSIONS Although associated with significantly improved surgical conditions, deep NMB alone was insufficient to promote use of low insufflation pressure during laparoscopic cholecystectomy. Furthermore, low insufflation pressure did not result in reduced pain, compared with standard pressure. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov identifier, NCT01728584.

Abstract
STUDY OBJECTIVE To investigate possible effects of volatile induction and maintenance anesthesia with sevoflurane (VIMA) and total intravenous anesthesia with propofol (TIVA) on regional cerebral oxygen saturation (rcSo2) during laparoscopic cholecystectomy. DESIGN Randomized, prospective and single-blinded study. SETTING Academic hospital. PATIENTS ASA physical status of I and II surgical patients, scheduled for elective laparoscopic cholecystectomy from March 2013 to October 2014. MEASUREMENTS Changes of regional cerebral oxygen saturation were measured by near-infrared spectroscopy on the left and right sides of forehead at different time points: before anesthesia induction (Tbas), immediately after induction (Tind), after applaying a pneumoperitoneum (TCo2), 10 minutes after positioning the patient into reverse Trendelenburg's position (TrtCo2), immediately after desufflation of gas (Tpost) and 30 (Trec30) and 60 (Trec60) minutes after emergence from anesthesia. MAIN RESULTS Study population included 124 patients, 62 in each group. There was no significant difference between these groups according to demographic characteristics, surgery and anesthesia times as well as in the basal rcSo2 values. Statistically higher rSco2 values were noted in the VIMA group when compared to the TIVA group in all time points Tind, TCo2, TrtCo2, Tpost, Trec30 and Trec60 and incidence of critical rcSo2 decreases was statistically lower in VIMA group (P<.05). There were no serious perioperative complications. CONCLUSIONS VIMA technique provides significantly (4%-11%) higher rcSO2 values during general anesthesia for laparoscopic cholecystectomy, when compared with TIVA and also provides significantly less number of critical rcSO2 decreases.

Surg Endosc 2016; 31:974-980. [PMID: 27501727 DOI: 10.1007/s00464-016-5013-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2016] [Accepted: 05/31/2016] [Indexed: 10/21/2022]
Abstract
BACKGROUND A hands-free region-of-interest (ROI) selection interface is proposed for solo surgery using a wide-angle endoscope. A wide-angle endoscope provides images with a larger field of view than a conventional endoscope. With an appropriate selection interface for a ROI, surgeons can also obtain a detailed local view as if they moved a conventional endoscope in a specific position and direction. METHODS To manipulate the endoscope without releasing the surgical instrument in hand, a mini-camera is attached to the instrument, and the images taken by the attached camera are analyzed. When a surgeon moves the instrument, the instrument orientation is calculated by an image processing. Surgeons can select the ROI with this instrument movement after switching from 'task mode' to 'selection mode.' The accelerated KAZE algorithm is used to track the features of the camera images once the instrument is moved. Both the wide-angle and detailed local views are displayed simultaneously, and a surgeon can move the local view area by moving the mini-camera attached to the surgical instrument. RESULTS Local view selection for a solo surgery was performed without releasing the instrument. The accuracy of camera pose estimation was not significantly different between camera resolutions, but it was significantly different between background camera images with different numbers of features (P < 0.01). The success rate of ROI selection diminished as the number of separated regions increased. However, separated regions up to 12 with a region size of 160 × 160 pixels were selected with no failure. Surgical tasks on a phantom model and a cadaver were attempted to verify the feasibility in a clinical environment. CONCLUSIONS Hands-free endoscope manipulation without releasing the instruments in hand was achieved. The proposed method requires only a small, low-cost camera and an image processing. The technique enables surgeons to perform solo surgeries without a camera assistant.

Abstract
OBJECTIVE To compare the variation in pneumoperitoneum and physiologic effects of patients undergoing laparoscopic renal surgery using the valveless trocar insufflation system (VI) vs a conventional insufflation system (CI). METHODS AND MATERIALS We conducted a single-center, randomized controlled trial in patients undergoing renal surgery at 15 mm Hg insufflation using a VI system vs a CI system. The primary outcome measured was variation in insufflation pressure, and end-tidal CO2 at 10 and 25 minutes. RESULTS Fifty-six patients (VI n = 28 or CI n = 28) met inclusion criteria and were randomized. There was significantly less variability in pressure readings, as measured by coefficient of variation, during VI compared to CI (7.8% vs 15.6%, P < .001). There was significantly less time spent within the range with pressure readings ≥18 mm Hg (median 0.2% vs 16.5%, P < .001) and ≤12 mm Hg (median 1.7% vs 5.6%, P = .011) during VI compared to CI. Additionally, there was significantly less time spent with pressure readings in the "unacceptable" range of ≥20 mm Hg (median 0% vs 0.08%, P < .001) and ≤10 mm Hg (median 0.09% vs 2.6%, P < .001) during the cases with VI compared to CI. End-tidal CO2 was significantly lower at 10 minutes (P = .036) after insufflation in the valveless trocar group compared to the conventional treatment group. There were no other significant differences in physiologic metrics. CONCLUSION Compared with a CI, the VI provides a significantly more stable pneumoperitoneum during laparoscopic renal surgery and lower end-tidal CO2 at 10 minutes.

Abstract
Populations are aging worldwide, people are living longer, and the surgical needs of elderly patients are rising. Laparoscopic techniques have become more common with improved training, surgeon skill and evidence of improved outcomes. Benefits of laparoscopy include decreased blood loss, postoperative pain, and hospital length of stay; improved mobilization, quicker return to normal activity; and fewer pulmonary, thrombotic, and abdominal wall complications. Indeed, for many common pathologies laparoscopy has become the gold standard, unless contraindicated. It has been questioned as to whether elderly patients can reap the same benefits from laparoscopic surgery. The concern in elderly patients is that physiologic demands may outweigh the benefit seen in younger patients. This question stems from concerns related to longer operative times, increased technical challenge, as well as the impact of physiologic demands of pneumoperitoneum and patient positioning. However, with anesthesia and adequate perioperative cardiac care, there is no evidence that these factors lead to worse clinical outcomes in elderly patients. In contrast, perhaps elderly patients - with increased prevalence of multi-morbidity, geriatric syndromes and diminished physiologic reserve - have the most to gain from a laparoscopic approach.

Abstract
BACKGROUND A recent study demonstrated that high pressure of carbon dioxide (CO2) pneumoperitoneum before liver resection impairs postoperative liver regeneration. This study was aimed to investigate effects of varying insufflation pressures of CO2 pneumoperitoneum on liver regeneration using a rat model. METHODS 180 male Wistar rats were randomly divided into three groups: control group (without preoperative pneumoperitoneum), low-pressure group (with preoperative pneumoperitoneum at 5 mmHg), and high-pressure group (with preoperative pneumoperitoneum at 10 mmHg). After pneumoperitoneum, all rats were subjected to 70% partial hepatic resection and then euthanized at 0 min, 12 h, and on postoperative days (PODs) 1, 2, 4, and 7. Following outcome parameters were used: liver regeneration (liver regeneration rate, mitotic count, Ki-67 labeling index), hepatocellular damage (serum aminotransferases), oxidative stress [serum malondialdehyde (MDA)], interleukin-6 (IL-6), and hepatocyte growth factor (HGF) expression in the liver tissue. RESULTS No significant differences were observed for all parameters between control and low-pressure groups. The liver regeneration rate and mitotic count were significantly decreased in the high-pressure group than in control and low-pressure groups on PODs 2 and 4. Postoperative hepatocellular damage was significantly greater in the high-pressure group on PODs 1, 2, 4, and 7 compared with control and/or low-pressure groups. Serum MDA levels were significantly higher in the high-pressure group on PODs 1 and 2, and serum IL-6 levels were significantly higher in the high-pressure group at 12 h and on POD 1, compared with control and/or low-pressure groups. The HGF tissue expression was significantly lower in the high-pressure group at 12 h and on PODs 1 and 4, compared with that in control and/or low-pressure groups. CONCLUSIONS High-pressure pneumoperitoneum before 70% liver resection impairs postoperative liver regeneration, but low-pressure pneumoperitoneum has no adverse effects. This study suggests that following laparoscopic liver resection using appropriate pneumoperitoneum pressure, no impairment of liver regeneration occurs.

Abstract
INTRODUCTION Operative time is an accepted risk factor for the development of postoperative ileus (POI). Innovative surgical procedures such as robotic surgery and natural orifice transluminal endoscopic surgery (NOTES) will be associated with longer operative times. Although intraabdominal manipulation is a major factor for POI the impact of prolonged capnoperitoneum on postoperative gastrointestinal transit time (GIT-TT) has rarely been studied. MATERIAL AND METHODS IRB approved survival pilot study to assess postoperative GIT-TT using fecal collection and chromium-oxide (Cr2O3) labeling in pigs. Twelve female pigs were randomly assigned to three groups of four animals each. Group A received eight hours anesthesia and pressure-controlled high flow capnoperitoneum (15 mmHg), group B eight hours of anesthesia only and group C no intervention. No intraoperative manipulation. The pilot study was terminated after eight days. RESULTS None of the animals developed POI. In Group A one animal died after eight hours of general anesthesia. No differences in postoperative fecal output, Cr2O3 excretion rate or weight gain were found. CONCLUSION This study is the first to investigate eight hours of capnoperitoneum in a survival model. GIT-TT is not affected by prolonged capnoperitoneum in pigs. No POI occurred with prolonged capnoperitoneum. Prolonged capnoperitoneum is safe regarding postoperative gastrointestinal function in innovative surgical procedures.
