Current Status of Laparoscopic Liver Resection.

The evolution of laparoscopic liver surgery, originating in the 1990s, has been marked by significant advancements and milestones, overcoming initial technical hurdles and gaining widespread acceptance within the surgical community as a precise and safe alternative to open procedures. Along this journey, numerous challenges emerged, leading to the accumulation of evidence and the development of guidelines aimed at assisting surgeons in determining the safety, suitability, and complexity of laparoscopic liver resection. This chapter provides a thorough examination of key aspects of laparoscopic liver resection, including difficulty scoring systems, criteria for patient selection, technical considerations, outcomes across different types of liver lesions, and the innovative solutions developed to address challenges, thus offering a comprehensive overview of laparoscopic liver resection, and highlighting its evolving significance in modern hepatobiliary surgery.

Usefulness of Deloyers procedure with minimally invasive coloproctectomy in an elderly patient with synchronous colorectal cancer: A case report.

Subtotal colectomy is often performed on patients with synchronous colorectal cancer. However, compared with colorectal anastomosis, ileorectal anastomosis with subtotal colectomy is more likely to result in bowel dysfunction. The Deloyers procedure is useful in preserving bowel function in a patient with synchronous colorectal cancer. An 87-year-old man presented with bloody stool. Colonoscopy showed masses in the cecum, transverse colon, rectosigmoid, and rectum above the peritoneal reflection. Computed tomography scan revealed no evidence of regional lymph node swelling and distant metastasis. Therefore, robot-assisted low anterior resection, laparoscopic extended left hemicolectomy, laparoscopic cecal resection, and diverting ileostomy were performed. The patient was discharged from the hospital without complications. There was no recurrence, and the patient did not have complaints such as urgency, fecal incontinence, and excretory dysfunction. Hence, minimally invasive coloproctectomy using the Deloyers procedure can be safe and useful in preserving postoperative bowel function in elderly patients.

Laparoscopic D3 right hemicolectomy with intracorporeal anastomosis.

Complete mesocolic excision (CME) with D3 lymphadenectomy for colon cancer has been shown to improve overall as well as disease-free survival compared to conventional right hemicolectomy. Performing a laparoscopic CME/D3 right hemicolectomy with intracorporeal anastomosis (ICA) can be technically demanding even for experienced operators. Here, we present a systematic, standardized approach to the surgery.

Emergency robotic surgery: the experience of a single center and review of the literature.

BACKGROUNDS: Laparoscopic surgery is widely used in abdominal emergency surgery (AES), and the possibility of extending this approach to the more recent robotic surgery (RS) arouses great interest. The slow diffusion of robotic technology mainly due to high costs and the longer RS operative time when compared to laparoscopy may represent disincentives, especially in AES. This study aims to report our experience in the use of RS in AES assessing its safety and feasibility, with particular focus on intra- and post-operative complications, conversion rate, and surgical learning curve. Our data were also compared to other experiences though an extensive literature review. METHODS: We retrospectively analysed a single surgeon series of the last 10 years. From January 2014 to December 2023, 36 patients underwent urgent or emergency RS. The robotic devices used were Da Vinci Si (15 cases) and Xi (21 cases). RESULTS: 36 (4.3%) out of 834 robotic procedures were included in our analysis: 20 (56.56%) females. The mean age was 63 years and 30% of patients were ≥ 70 years. 2 (5.55%) procedures were performed at night. No conversions to open were reported in this series. According to the Clavien-Dindo classification, 2 (5.5%) major complications were collected. Intraoperative and 30-day mortality were 0%. CONCLUSIONS: Our study demonstrates that RS may be a useful and reliable approach also to AES and intraoperative laparoscopic complications when performed in selected hemodynamically stable patients in very well-trained robotic centers. The technology may increase the minimally invasive use and conversion rate in emergent settings in a completely robotic or hybrid approach.

Preoperative bedside test indicators as predictors of difficult video laryngoscopy in obese patients: a prospective observational study.

Purpose: The aim of this study was to identify factors associated with difficult video laryngoscopy in obese patients. Methods: A total of 579 obese patients undergoing elective laparoscopic weight loss surgery were intubated with a single-lumen endotracheal tube using a video laryngoscopy under general anesthesia, and the patients were divided into two groups based on the Cormack-Lehane classification (difficult video laryngoscopy defined as ≥ 3): the easy video laryngoscopy group and the difficult video laryngoscopy group. Record the general condition of the patient, bedside testing indicators related to the airway, Cormack-Lehane classification during intubation, and intubation failure rate. Results: The findings of this study show that the incidence of difficult video laryngoscopy in obese patients is 4.8%. Multivariate logistic regression analysis indicated that body mass index was significantly associated with difficult video laryngoscopy (OR = 1.082, 95% CI [1.033-1.132], P < 0.001). Conclusion: For Chinese obese patients without known difficult airways, the incidence of difficult video laryngoscopy is 4.8%. Body mass index is associated factors for the occurrence of difficult video laryngoscopy, with an increased risk observed as body mass index rise.

Anaesthetic implications in situs inversus totalis: A case report.

Situs inversus totalis (SIT) is a rare congenital condition which is characterised by the reversal of orientation of abdominal and thoracic organs where heart is on the right side of the thoracic cavity and liver on the left side, whereas stomach and spleen are on the right side in the abdomen. The reported prevalence of this anomaly is one in 5,000- 20,000 live births. This case reports the anaesthetic management of situs inversus totalis in a 38-year-old male patient, with a history of poorly differentiated adenocarcinoma of the colon, who underwent laparoscopic intervention converted to open nodular excision with incisional hernia repair. The report analyses the anaesthetic implications and challenges associated with situs inversus totalis during surgery, including preoperative evaluation, monitoring techniques and potential complications.

The effect of enhanced recovery after surgery (ERAS) in renal surgery.

OBJECTIVE: To study the effect of ERAS on a textbook outcome (TO) after elective renal surgery. PATIENTS AND METHODS: Retrospective study of all patients who underwent a robot-assisted laparoscopic partial or radical nephrectomy or robot-assisted laparoscopic radical nephroureterectomy in Medisch Spectrum Twente (MST), Enschede, the Netherlands. In total, 277 patients were included. 66 patients from 2018 to 2021 (pre-ERAS group) and 211 patients from 2021 to 2023 (ERAS group). TO is a maximum of two nights in the hospital after surgery, no severe complications during or after surgery ≥ grade IIIb, no blood transfusions, no intensive care, no readmissions, and no mortality within 30 days after surgery. Comparisons were made between the pre-ERAS and ERAS groups using unpaired t-test, Mann-Whitney U test, the chi-squared test or Fisher's exact test. Multivariate logistic regression was used to adjust for possible confounding. RESULTS: TO was significantly (p = 0.005) better in the ERAS group (TO = 76.8%) compared to the pre-ERAS group (TO = 59.1%). Compared to a pre-ERAS patient, the adjusted odds ratio for achieving a TO as an ERAS patient is 2.1 (95% CI 1.15-3.78). CONCLUSIONS: The implementation of ERAS showed a positive effect on the TO of elective renal surgery patients.

Proposal for standardization of laparoscopic D3 lymphadenectomy for right colon cancer.

BACKGROUND: This study presents a laparoscopic surgical protocol for right hemicolectomy and D3 lymphadenectomy (R-D3L) in right colon cancer and reports the oncological outcomes based on a prospective series. METHODS: The study comprises two phases. In the first phase, a dynamic demonstration of the R-D3L surgical protocol is provided through textual explanation, illustrations, and edited surgical videos. The protocol emphasizes technical steps such as dissection of the embryological plane of the right mesocolon, high tie of ileocolic vessels, surgical trunk of Gillot dissection, and high tie of superior right colic vein (SRCV). In the second phase, a prospective observational study was conducted involving patients undergoing R-D3L surgery with this protocol between July 2015 and July 2021. Demographic, perioperative, and postoperative variables are analyzed, along with anatomopathological variables and oncological outcomes. RESULTS: A total of 33 patients were analyzed. Median operative time was 202 min. Perioperative bleeding occurred in 6%. Postoperative complications were mild (Clavien-Dindo III in 2%). Postoperative ileus was observed in 15%. No anastomotic dehiscence was reported. The median postoperative stay was 7 days. The median number of resected lymph nodes was 26, with 27% having positive nodes and 70% were classified as stage T3 or T4. After a median follow-up of 45 months, local recurrence, distant recurrence, and carcinomatosis rates were 0%. Mortality rate from other causes was 9%. CONCLUSION: The surgical protocol shown in the present study could help in the implementation of this technique in those units that consider it appropriate.

Risk factors of textbook outcome in laparoscopic pancreatoduodenectomy: results from a prospective high-volume center study.

OBJECTIVE: Achieving textbook outcome (TO) implies a smooth recovery post-operation without specified composite complications. This study aimed to evaluate TO in laparoscopic pancreaticoduodenectomy (LPD) and identify independent risk factors associated with achieving TO. METHODS: We conducted a retrospective analysis of data from a randomized controlled trial on LPD at West China Hospital (ChiCTR1900026653). Patients were categorized into the TO and non-TO groups. Perioperative variables were compared between these groups. Multivariate logistic regression was utilized to identify the risk factors. RESULTS: A total of 200 consecutive patients undergoing LPD were included in this study. TO was achieved in 82.5% (n = 165) of the patients. Female patients (OR: 2.877, 95% CI: 1.219-6.790; P = 0.016) and those with a hard pancreatic texture (OR: 2.435, 95% CI: 1.018-5.827; P = 0.046) were associated with an increased likelihood of achieving TO. CONCLUSIONS: TO can be achieved in more than 80% of patients in a high-volume LPD center. Independent risk factors associated with achieving TO included gender (male) and pancreatic texture (soft).

Educational Level of Laparoscopic Radical Nephrectomy Videos on YouTubeTM.

Purpose: This study aims to evaluate the educational quality and appropriateness of laparoscopic radical nephrectomy videos on YouTube using the LAParoscopicsurgery Video EducationalGuidelineS (LAP-VEGaS) criteria. It focuses on understanding the role of online resources in medical education and objectively assessing their quality. Methods: A search was conducted on YouTube™ for "laparoscopic radical nephrectomy" on August 15, 2023, leading to the selection of the first 125 videos. Videos were chosen based on length (over 1 minute), content (laparoscopic radical nephrectomy), language (English), and nonindustry sponsorship. The LAP-VEGaS criteria, encompassing 16 items under five main categories: video introduction, case presentation, procedures, outcomes, and educational content, were used for evaluation, assigning 0 or 1 point per criterion. Results: Out of 100 videos meeting the criteria, they were divided into two groups: personal uploads by expert surgeons (Group-1) and institutional uploads by hospitals and organizations (Group-2). Group-2 videos had longer durations and higher LAP-VEGaS scores. The transperitoneal approach was preferred in 88% of the videos, and 84% were right laparoscopic nephrectomies. Group-2 had significantly higher LAP-VEGaS scores (6.3 ± 2.2) compared with Group-1 (4 ± 2.1) (P < 0,001). The number of videos published over the years increased, while LAP-VEGaS scores fluctuated. Conclusion: Assessing laparoscopic radical nephrectomy videos on YouTube™ using the LAP-VEGaS criteria helped understand the role of online sources in medical education. Institutional uploads were found to be more successful in educational aspects, emphasizing the need for continuous quality review of online medical education materials. This study also guides how to evaluate and improve medical education materials on online platforms.

Evaluation of the suitability of using ArtiSential in various renal surgery: IDEAL stage 1 study.

BACKGROUND: ArtiSential, a new articulating laparoscopic instruments, addresses the limited movement associated with conventional laparoscopic instruments. This study was conducted to assess the clinical effectiveness of ArtiSential in detailed steps of various renal surgery. METHODS: This study was approved by the Institutional Review Board of our institution and registered on the Clinical Research Information Service site of the Korea Disease Control and Prevention Agency. Participants meeting all inclusion and exclusion criteria were included in the clinical trial and underwent renal surgery. The clinical effectiveness of ArtiSential was assessed in terms of the feasibility and objective and subjective parameters across 9 detailed steps. RESULTS: Of the 15 potential candidates enrolled from October 2021 to November 2021, 1 patient dropped out due to anaphylaxis from an anesthetic agent, and 14 patients underwent laparoscopic surgery using ArtiSential. Of the 14 patients, 2 patients were converted to laparoscopic surgery using straight-shaped instruments due to the ischemia time exceeding 30 min, and 1 patient due to excessive bleeding. The feasibility for most steps was more than 90%, except the renorrhaphy step. The median total operation time and ischemia time were 161 and 23 min, respectively. The median estimated blood loss was 58.5 mL. Two cases of venous injury occurred during renal pedicle dissection step. The accuracy of the procedure judged by reviewers and usability judged by the operator were acceptable in all steps. The surgeon's quantitatively measured stress score was the highest during renorrhaphy step. CONCLUSIONS: Laparoscopic surgery using ArtiSential is feasible for most steps except the renorrhaphy step. The difficulty of performing renorrhaphy is attributed to prolonged ischemia time, which could be addressed by overcoming the learning curve.

Surgical outcomes and prognosis of intracorporeal versus extracorporeal esophagojejunostomy after laparoscopic total gastrectomy for gastric cancer: a propensity score-matching study.

This study compared the surgical outcomes and long-term prognosis of intracorporeal and extracorporeal esophagojejunostomy after laparoscopic total gastrectomy (LTG) for gastric cancer patients. In total 228 clinical stage I gastric cancer patients undergoing LTG were enrolled from January 2012 and December 2022. Each case in the totally laparoscopic total gastrectomy (TLTG) group was 1:1 propensity score-matched to control cases in the laparoscopy-assisted total gastrectomy (LATG) group. In total, 95 and 93 LATG and TLTG patients were included after propensity score matching (PSM). Clinicopathological features, surgical outcomes, and survival variables were compared, and risk factors for postoperative complications were analyzed. Patient characteristics were well balanced between the LATG and TLTG groups after PSM. The TLTG group showed less blood loss, decreased frequency of analgesic use, and shorter duration of analgesic use. The TLTG group had significantly lower rates of intestinal obstruction and surgical site infection. Larger tumor size and advanced pTNM stage were independent risk factors for postoperative complications. There was no significant difference in overall survival (OS). Compared with LATG, TLTG was associated with better surgical outcomes and fewer postoperative surgical complications in gastric cancer patients although there was no significant difference in OS.

Comparative efficacy of bilateral mesh sacrospinous ligament suspension versus laparoscopic sacrocolpopexy in patients with metroptosis.

This study assesses the efficacy of bilateral mesh sacrospinous ligament suspension (MSSLS) compared to laparoscopic sacrocolpopexy (LSC) in patients with uterine prolapse. Ninety-eight patients with uterine prolapse were evaluated at our hospital from January 2021 to January 2023. Patients were equally divided into two groups: the study group (undergoing MSSLS) and the control group (undergoing LSC) using a random number table. Various parameters including operation time, bleeding volume, indwelling catheter time, exhaust time, hospital stay, pelvic organ prolapse stage, postoperative recurrence rate, pain severity, quality of life, pelvic floor function, impact on sexual life, complications, and recurrence rate were recorded. The study group showed significant reductions in operation time, bleeding volume, indwelling catheter time, exhaust time, and hospital stay compared to the control group (P < 0.05). There were no significant differences in Aa, Ba, Ap, Bp, and C between the two groups before surgery (P > 0.05), but six months postoperatively, these indexes were significantly lower in the study group (P < 0.05). Pain severity did not differ significantly between the two groups before surgery (P > 0.05), but was significantly lower in the study group six months postoperatively (P < 0.05). Quality of life, pelvic floor function, and sexual life quality did not significantly differ before surgery, at 6 months, and at 12 months postoperatively (P > 0.05). All patients were followed up for 12-14 months, with an average follow-up time of (13.02 ± 1.36) months. The incidence of complications was significantly lower in the study group (P < 0.05), but there were no recurrences in either group, thus the difference was not statistically significant (P > 0.05). MSSLS emerges as a safe and efficacious treatment for uterine prolapse, notably reducing both complications and recurrence rates, rendering it suitable for broad clinical application.

Prevention of postpancreatectomy hemorrhage after laparoscopic pancreaticoduodenectomy by wrapping ligamentum teres hepatis surrounding hepatic portal artery.

Postpancreatectomy hemorrhage (PPH) is an important risk factor for postoperative complications after laparoscopic pancreaticoduodenectomy (LPD). Recent studies have reported that the use of ligamentum teres hepatis (LTH) in LPD may reduce the risk of PPH. Therefore, this study aims to investigate whether wrapping the hepatic hilar artery with the LTH can reduce PPH after LPD. We reviewed the data of 131 patients who underwent LPD in our team from April 2018 to December 2023. The patients were divided into Groups A (60 patients) and B (71 patients) according to whether the hepatic portal artery was wrapped or not. The perioperative data of the two groups were compared to evaluate the effect of LTH wrapping the hepatic hilar artery on LPD. The platelet count of Group A was (225.25 ± 87.61) × 10^9/L, and that of Group B was (289.38 ± 127.35) × 10^9/L, with a statistically significant difference (p < 0.001). The operation time of group A [300.00 (270.00, 364.00)] minutes was shorter than that of group B [330.00 (300.00, 360.00)] minutes, p = 0.037. In addition, A set of postoperative hospital stay [12.00 (10.00, 15.00)] days shorter than group B [15.00 (12.00, 19.50)] days, p < 0.001. No PPH occurred in Group A, while 8 patients in Group B had PPH (7 cases of gastroduodenal artery hemorrhage and 1 case of proper hepatic artery hemorrhage), p = 0.019. The new technique of wrapping the hepatic hilar artery through the LTH can effectively reduce the occurrence of PPH after LPD.

Positive end-expiratory pressure and postoperative pulmonary complications in laparoscopic bariatric surgery: systematic review and meta-analysis.

BACKGROUND: This study compares the effect of positive end-expiratory pressure (PEEP) on postoperative pulmonary complications (PPCs) in patients with obesity undergoing laparoscopic bariatric surgery (LBS) under general anesthesia with mechanical ventilation. METHODS: A comprehensive search was conducted in PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, China National Knowledge Internet, Wanfang database, and Google Scholar for studies published up to July 29, 2023, without time or language restrictions. The search terms included "PEEP," "laparoscopic," and "bariatric surgery." Randomized controlled trials comparing different levels of PEEP or PEEP with zero-PEEP (ZEEP) in patients with obesity undergoing LBS were included. The primary outcome was a composite of PPCs, and the secondary outcomes were intraoperative oxygenation, respiratory compliance, and mean arterial pressure (MAP). A fixed-effect or random-effect model was selected for meta-analysis based on the heterogeneity of the included studies. RESULTS: Thirteen randomized controlled trials with a total of 708 participants were included for analysis. No statistically significant difference in PPCs was found between the PEEP and ZEEP groups (risk ratio = 0.27, 95% CI: 0.05-1.60; p = 0.15). However, high PEEP ≥ 10 cm H2O significantly decreased PPCs compared with low PEEP < 10 cm H2O (risk ratio = 0.20, 95% CI: 0.05-0.89; p = 0.03). The included studies showed no significant heterogeneity (I2 = 20% & 0%). Compared with ZEEP, PEEP significantly increased intraoperative oxygenation and respiratory compliance (WMD = 74.97 mm Hg, 95% CI: 41.74-108.21; p < 0.001 & WMD = 9.40 ml cm H2O- 1, 95% CI: 0.65-18.16; p = 0.04). High PEEP significantly improved intraoperative oxygenation and respiratory compliance during pneumoperitoneum compared with low PEEP (WMD = 66.81 mm Hg, 95% CI: 25.85-107.78; p = 0.001 & WMD = 8.03 ml cm H2O- 1, 95% CI: 4.70-11.36; p < 0.001). Importantly, PEEP did not impair hemodynamic status in LBS. CONCLUSIONS: In patients with obesity undergoing LBS, high PEEP ≥ 10 cm H2O could decrease PPCs compared with low PEEP < 10 cm H2O, while there was a similar incidence of PPCs between PEEP (8-10 cm H2O) and the ZEEP group. The application of PEEP in ventilation strategies increased intraoperative oxygenation and respiratory compliance without affecting intraoperative MAP. A PEEP of at least 10 cm H2O is recommended to reduce PPCs in patients with obesity undergoing LBS. REGISTRATION NUMBER: CRD42023391178 in PROSPERO.
