For centuries, surgeons have relied on their sense of touch to identify vital structures such as blood vessels in traditional open surgery. Over the past two decades, surgeons have shifted to minimally invasive surgical (MIS) approaches, including laparoscopic surgery, which include benefits such as less scarring, less risk for infection, and quicker recovery times. In fact, some surgeries such as cholecystectomies have seen more than an 80% adoption of this technique because of those benefits. However, due to the fundamental challenges associated with using laparoscopic surgery, there has been a lower adoption in more complex specialties, such as colorectal and thoracic surgery, where the field of surgery has bleeding, fat, scar tissue, and adhesions...

OBJECTIVES: Early stage lung cancer is being detected at a higher frequency with the implementation of screening programs. At the same time, medically complex patients with multiple comorbidities are presenting for surgery, with a concomitant rise in rates of sublobar resection. We sought to examine the effect of sampling lymph nodes on the outcomes of patients who undergo sublobar resection for small (<2 cm) stage I non-small cell lung cancer (NSCLC). METHODS: All patients in the Surveillance, Epidemiology, and End Results database from 2004 to 2013 with small (<2 cm) stage I NSCLC who underwent sublobar resection (wedge/segmentectomy) and no other cancer history were included...

Introduction: Open radical cystectomy (RC) is associated with significant morbidity and the role of minimally invasive surgery (MIS) in reducing morbidity of RC is controversial A direct comparison of various surgical modalities on perioperative outcomes is lacking in the Indian literature. We evaluated outcomes of minimally invasive (robotic and laparoscopic) versus open RC with pelvic lymph node dissection (PLND) performed at our institute from 2014 to 2016. Methods: Eighty-three patients of RC with PLND were prospectively analyzed from December 2014 to February 2016...

OBJECTIVE: To evaluate patient-reported outcomes (PROs) between women treated by laparoscopic, robotic and open approaches for endometrial cancer. METHODS: Prospective cohort study comparing PRO at baseline, short- (1 and 3 weeks) and long-term (12 and 24 weeks) follow-up postoperatively. Quality of life (QOL) measures were the Functional Assessment of Cancer Therapy (FACT-G), EuroQol Five Dimensions (EQ-5D), and Brief Pain Inventory (BPI). Sexual health measures were the Female Sexual Function Index (FSFI) and the Sexual Adjustment and Body Image Scale for Gynecologic Cancer (SABIS-G)...

OBJECTIVE: To investigate cancer- and noncancer-specific mortality following lobectomy by minimally invasive surgery (MIS) versus open thoracotomy in elderly patients with nonsmall cell lung cancer (NSCLC). BACKGROUND: Two-thirds of patients with NSCLC are ≥65 years of age. As age increases, the risk of competing events, such as noncancer death, also increases. METHODS: Elderly patients (≥65 yrs of age) who have undergone curative-intent lobectomy for stage I-III NSCLC without induction therapy (2002-2013) were included (n=1,303)...

BACKGROUND: Long-term oncologic outcomes after minimally invasive surgery (MIS) for rectal adenocarcinoma compared to open surgery continue to be debated. We aimed to review our high-volume single-institution outcomes in MIS rectal cancer surgery. METHODS: A retrospective review of a prospectively collected database was completed of all consecutive adult patients with rectal adenocarcinoma treated from January 2005 through December 2011. Stage IV or recurrent disease was excluded...

Background: The evolution of minimally invasive surgery (MIS) also extends to the field of esophageal surgery and has brought forth the development of several approaches of minimally invasive esophagectomy (MIE). Hybrid and total minimally invasive operative techniques have proven beneficial compared to open surgery and are currently evaluated against robotic-assisted minimally invasive esophagectomy (RAMIE). We aim to review the current literature regarding the position of MIE versus RAMIE...

INTRODUCTION: Minimally invasive surgery (MIS) for gallbladder cancer (GBCa) has traditionally been discouraged, with limited studies reporting on its outcomes. The aim of this study was to evaluate the short-term outcomes of MIS for patients with GBCa or suspected GBCa. METHODS: A retrospective study of 8 consecutive patients who underwent MIS for GBCa by a single surgeon over a 22-month period between 2015 and 2017. RESULTS: Three patients underwent robotic surgery, while five underwent conventional laparoscopic surgery...

AIM: Transanal transabdminal-proctosigmoidectomy with a coloanal anastomosis (TATA) is an alternative to to abdomino-perineal resection of the rectum (APR) for low rectal cancer. Neorectal prolapse is an unusual complication following TATA.. This study aimed to determine the incidence of neorectal prolapse after TATA for low rectal cancer. METHODS: this cohort study was conducted in a tertiary referral colorectal center. From a prospectively maintained database which includes 1,093 patients treated for rectal cancer between 1984-2016) we identified those who underwent sphincter-preserving surgery...

BACKGROUND: Narrow band imaging (NBI) is an optic filtration enhancement for endoscopy that uses two wavelengths of light (415 and 540 nm) to highlight superficial microvascular patterns. It has been successfully utilized to improve identification of lesions with abnormal vasculature, which is associated with endometriosis and endometrial cancer. Case studies suggest it may also facilitate surgical staging of gynecologic cancer, which is critical in determining appropriate adjuvant therapies...

Gastric cancer remains one of the most aggressive malignancies, being associated with very poor therapeutic outcomes, especially in the advanced disease patients. Due to this evidence, finding a better treatment, a better control and higher survival rates is the current scientific focus of the medical community. Once the benefits of cytoreductive surgery in association with intraperitoneal hyperthermy (HIPEC) have been widely demonstrated in patients presenting peritoneal carcinomatosis from colorectal or ovarian origin,attention was focused on the possible benefit of this method in patients diagnosed with peritoneal carcinomatosis with gastric origin...

Mini-invasive surgery is more and more integrated in pediatric surgery. The robotic-assisted surgery brought new advantages from which the patient and the surgeon could benefit compared to laparoscopy. Its use in oncological surgery is still controversial. 12 robotic-assisted tumor resections with the da Vinci Surgical Robot (Intuitive Surgical, Sunnyvale, CA) were attempted in 11 children (mean age 7.65 years; age range 0.75-16.75 years; mean weight 30.3 kg; weight range 8.6-62 kg) in two centers. Mean total operative time was 145 min (range 72-263 min)...

BACKGROUND AND OBJECTIVES: During minimally invasive surgery (MIS), it is impossible to directly detect marked clips around tumors via palpation. Therefore, we developed a novel method and device using Radio Frequency IDentification (RFID) technology to detect the position of clips during minimally invasive gastrectomy or colectomy. METHODS: The feasibility of the RFID-based detection system was evaluated in an animal experiment consisting of seven swine. The primary outcome was to successfully detect the location of RFID clips in the stomach and colon...

The laparoscopic surgery for gastrointestinal cancer developed slowly and was at a crossroad of choice at the beginning of the 21st century. However, the team of laparoscopic surgery in Nanfang Hospital was keenly conscious that minimally invasive surgery (MIS) would bring new era to the treatment of gastrointestinal cancer. Therefore, our team went into the exploration of laparoscopic surgery for gastrointestinal cancer: (1) researching a series of anatomical theories for MIS; (2) lucubrating the applicable pattern of fascia and mesentery under laparoscopic view; (3) finding out the precise anatomical landmarks and surgical layers; (4) optimizing the operative strategy...

BACKGROUND: Randomized controlled trials (RCTs) inform clinical practice and have provided the evidence base for introducing minimally invasive surgery (MIS) in surgical oncology. Crossover (unplanned intraoperative conversion of MIS to open surgery) may affect clinical outcomes and the effect size generated from RCTs with homogenization of randomized groups. OBJECTIVES: Our aims were to identify modifiable factors associated with crossover and assess the impact of crossover on clinical endpoints...
