Conversion to Open Surgery

Conversion to Open Surgery is a medical procedure where a minimally invasive surgical approach is converted to an open surgical approach during the course of a procedure.
This may occur due to technical difficulties, anatomical limitations, or other intraoperative factors that make the minimally invasive approach impractical or unsafe.
The open surgical approach typically provides better visualization and access to the surgical site, but may result in a larger incision and potentially longer recovery time for the patient.

From November 2008, RG was introduced in the Ajou University Hospital (Suwon, Korea). After 517 cases of LG were performed, we prospectively collected patients' demographic data (e.g., sex, age, underlying disease), operating data (e.g., operative time, bleeding, anastomosis type), and post-operative data (e.g., pathology, discharge date, morbidity). Five hundreds seventeen cases of LG were done by one surgeon, and all RG also done by same surgeon. Total 382 cases were enrolled in this study and RG cases were 100. The patients who underwent RG were divided into an initial 20 cases and all subsequent cases.
We defined "underlying disease" as "disease that could affect general anesthesia," and "operating time" as "the time from the initial incision to skin closure." We counted blood loss that suction volume minus irrigation volume. A complication was defined as "an event that delays the normal discharge date".
From November 2008 to March 2011, we reviewed gastric cancer patients who underwent minimally invasive surgeries (RG or LG). Patients whose pre-operative staging was 'T1 or 2' and 'N0 or 1' (American Joint Committee on Cancer [AJCC] 6th edition) were indicated for minimally invasive surgery. RG was selected if patients wanted this type of surgery, regardless of its cost. Combine operation which associated with stomach operation case was included (cholecystectomy or splenectomy) but other combine operation cases were excluded. Open conversion cases or palliative surgery cases were excluded, and there was no conversion to open surgery in robot-assisted cases. We reviewed the operative data and early operative outcomes and analyzed these factors retrospectively.

This study aims to show feasibility of C-Tr-RPD. The main study endpoint was therefore a composite index made by conversion to open surgery due to inability to complete triangle dissection or need to use energy devices to do so (i.e., harmonic shears and/or radiofrequency or microwave-powered devices).
Secondary study endpoints were incidence and severity of postoperative complications [18 (link)], post-pancreatectomy hemorrhage (PPH) [19 (link)], delayed gastric emptying (DGE) [20 (link)], and chyle leak [21 (link)]. Postoperative complications ≥ grade III, according to Clavien–Dindo [18 (link)], were considered severe complications. The cumulative burden of postoperative complications was estimated using the comprehensive complication index (CCI) [22 (link)].
The following parameters were also recorded: operative time, pylorus preservation, need and type of vascular resection [23 (link)], length of hospital stay, 90-day hospital readmission, 90-day mortality, 90-day mortality following completion of the learning curve [24 (link)], reoperation, and interventional procedures.
All specimens were analyzed according to the LEEPP protocol [25 (link)], as previously reported in detail [26 (link)]. Seven margins were assessed: anterior surface, posterior surface, vein bed, SMA groove, pancreatic neck, proximal duodenum/stomach, and common bile duct. Margins were defined positive (R1) if tumor cells were detected ≤ 1 mm of any margin.
Additional pathology data included tumor type (i.e., PDAC or malignant IPMN), tumor size, T status, N status, presence of perineural infiltration, number of examined lymph nodes, and number of metastatic lymph nodes.

A retrospective review of a prospectively collected database of 179 consecutive patients who underwent LCBDE at a single centre between February 2014 and December 2018 was performed. All operations were performed or supervised by the senior surgeon (AI). After review of the medical records, investigation results and operative notes, all patients were assigned into two groups based on whether or not LABEL was utilised. All patients were assessed with pre-operative liver function tests (LFTs) and abdominal imaging. Patients in our institution routinely undergo pre-operative ultrasound and then intra-operative cholangiography (IOC) to identify CBD stone burden and position. In patients with very high bilirubin levels or where there is clinical suspicion of another pathology, such as a biliary malignancy, patients undergo cross-sectional imaging, usually magnetic resonance cholangiopancreatography (MRCP). In our centre, patients with acute cholecystitis and CBD stones routinely undergo LCBDE, with endoscopic retrograde cholangiopancreatography (ERCP) being reserved for high-risk surgical patients, patients diagnosed with acute cholangitis and those patients who have had cholecystitis for greater than one week, in line with international guidelines [5 ].
Data collected included pre-operative demographic information, medical co-morbidity, pre-operative investigations, intra-operative findings and post-operative outcomes. Clinical presentation was classified into four groups: dilated CBD, deranged LFTs, jaundice and pancreatitis. Patients with bilirubin more than two times the upper limit of normal were classified as ‘jaundiced’ irrespective of the liver enzymes (alanine aminotransferase (ALT) and alkaline phosphatase (ALP)) or diameter of the CBD. Those patients with abnormal liver enzymes but bilirubin within the normal range or less than two times the upper limit of normal were classified as ‘deranged LFTs’ irrespective of CBD diameter, whereas patients with intra- or extra-hepatic duct dilatation on pre-operative imaging and normal bilirubin and liver enzymes were classified as ‘dilated CBD’. Outcomes of this study were stone clearance rates, TC exploration rate, conversion to open surgery, post-operative complications (Clavien-Dindo classification) and length of post-operative hospital stay. Length of post-operative hospital stay was chosen instead of total length of hospital stay because patients with acute cholecystitis, obstructive jaundice or pancreatitis were often admitted under the emergency surgery service and remained inpatients until their operation could be scheduled on to the next dedicated biliary operating list.

The study design was retrospective cohort study. The study proposal was approved by The Human Research Ethics Committee of Thammasat University (Medicine). The patients, who presented with symptomatic GS or complications of GS, then underwent LC since January 2017 to December 2021 in service of Hepato-Pancreato-Biliary and Transplantation unit in surgery department of Thammasat University Hospital, were considered to be enrolled into this study. The electronic medical record was thoroughly reviewed.
The important information including demographic data, clinical presentation, laboratory results, and radiological findings was collected. The operative time, intraoperative findings, perioperative complications, and conversion to open surgery were reviewed from operative notes. The laparoscopic procedure was carried out through three or four small incisions at umbilical and right upper quadrant areas. The operative time was counted from the opening of the first port-site incision to the closure of the last surgical wounds.
Some cases might be excluded because of the following reasons: (1) patients who underwent LC with other indication such as gallbladder polyp, (2) LC was performed in emergency setting for treatment of acute cholecystitis, and (3) there were any other procedures performed in the same setting of LC such as intraoperative ERCP. By the perioperative information, the patients were categorized into three groups by difficulty grading as given in Table 2.
The univariate analysis was performed using chi-square test for categorical data and Student's t-test for continuous data to define the significant factors affecting on very difficult LC and converted cases. Then multivariate analysis was carried out for both outcomes. Thereafter, the preoperative predictive scores of each patient were calculated using the original Randhawa scoring systems and also the modification of Tongyoo et al. The comparison between scores from both models was performed by many methods such as paired t-test, correlation coefficient, and area under receiver operating characteristic (ROC) curve. All of statistical analyses were performed by IBM SPSS® Statistics version 20 and their results were determined to be significant at P < .05.

All patients will receive localization and surgery within 1 week after randomization. Endoscopic tattooing with autologous blood and intraoperative colonoscopy will be performed by two experienced endoscopists who has more than thousands of cases colonoscopies and more than 200 cases of endoscopic mucosal resection or endoscopic submucosal dissection.
For patients who will enroll in autologous blood group, the tattooing will be performed at 24–48 hours before the surgery. When the lesion is identified by endoscopy, the patient’s peripheral venous blood will be collected using a 10 ml simple syringe without heparin preparation. Immediately after blood sampling, 2–3 ml of autologous blood will be injected submucosally at the distal side and proximal side of the lesion (about 2 cm below and above the border of the lesion) using a conventional endoscopic needle without submucosal injection of normal saline. The tattooing with autologous blood will consider to be invisible if both distal and proximal spots was not identified. For those receiving autologous blood localization, the case will be applied intraoperative colonoscopy if the autologous blood tattoo will not be identified or inaccurate in the laparoscopic colectomy.
For patients who will enroll in intraoperative colonoscopy group, the patient will be placed in the modified lithotomy position under general anesthesia with endotracheal intubation. The legs will be opened and positioned in padded stirrups to facilitate the insertion and manipulation of the colonoscope during the operation. After routine laparoscopic exploration, CO2-insufflated intraoperative colonoscopy will be performed using a flexible videocolonoscope. Upstream small bowel clamping will be applied before intraoperative colonoscopy. During intraoperative colonoscopy, CO2 pneumoperitoneum will be maintained by the insufflator so that the laparoscope could guide the colonoscope effectively.
After lesion will be identified, a standard laparoscopic colectomy will be performed by two experienced surgeons who has more than 20 years of experience in colorectal surgery with more than 200 cases per year for all enrolled patients. All abdominal operation of laparoscopy will be videotaped. Anastomosis will be performed using the instrumental method. The specimen will be pulled out through a small median incision under the xiphoid (about 3–8 cm).
For those receiving laparoscopic colectomy, the case will be required to be converted to open surgery if one of the following happens: severe or life-threatening intraoperative complications such as intra-abdominal massive haemorrhage, severe organ damage, or other technical or instrumental factors that require a conversion to open surgery.
