All of the RATG and LATG procedures were performed by a specific surgeon (TYL) with extensive experience in laparoscopic gastrectomy. All patients were conducted with endotracheal intubation and general anesthesia. During surgeries, the patients were placed in the supine and reverse Trendelenburg position with the legs elevated approximately 15°-20°and separated. Most of the operative steps in the RATG were the same as those in the LATG. Both operation procedures used a total of five trocars, adopts “W type” in RATG group and “U type” in LATG group. The camera port was inserted in the infraumbilical area by the closed method with a 12-mm trocar in RATG and a 10-mm trocar in LATG. Pneumoperitoneum was established with an intra-abdominal pressure of 12–15 mmHg by CO2 gas. Two 8-mm trocars for the first and the third robotic arm in RATG (one 12-mm trocar for operator and one 5-mm trocar for assistant in LATG) were placed in the left and right anterior axillary line just 2 cm below subcostal. One 8-mm trocar for second robotic arm and one 12-mm trocar for an assistant port in RATG (Two 5-mm trocars for operator and assistant in LATG) were placed through the left and right midclavicular line just 2 cm below (or above in LATG) umbilicus. The adjacent trocar distance is more than 8 cm to avoid interference between the manipulator. Standard D2 lymphadenectomy was performed in all procedures in accordance with the version 4 of Japanese Gastric Cancer Treatment Guidelines [15 (link)]. Afterward, the specimen was removed through a 6–8 cm mid-abdominal incision and Roux-en-Y esophagojejunostomy was performed with a 25 mm circular stapler. Seromuscular layer embedded was used to reinforce duodenal stump in all patients. Finally, two drainage tubes were placed near the duodenal stump and splenic recess respectively. The criteria to remove drainage tubes were the following: 1) the abdominal drainage volume less than 10 ml per day; 2) the drainage without odor; 3) patients without fever or peritonitis symptoms; 4) 4 days after operation.

To reconstruct the alimentary tract, we make either an end-to-side manual anastomosis between the colonic conduit and residual stomach or a jejunal Roux-en-Y anastomosis (colon-jejunum). The colon’s continuity is ultimately restored with an end-to-end manual anastomosis using continuous 4 − 0 monofilament sutures or with a side-to-side stapled anastomosis.

According to the PROCESS guidelines[10 (link)], a retrospective analysis was performed based on a single-center prospective case series. From May 2016 to June 2020, 11 patients were preoperatively diagnosed with colonic hepatic curl carcinoma with duodenal invasion at Panzhihua Central Hospital (Panzhihua, China). Before the operation, the hospital's gastrointestinal surgery specialists, internal medicine specialists, pathologists, radiologists, and imaging experts participated in the evaluation of the patient. The patients had undergone right semicolon carcinoma radical resection and duodenal-jejunal Roux-EN-Y anastomosis in the General Surgery Department of our hospital. None of them received neoadjuvant chemotherapy intervention prior to surgery. Surgeon Pei-Gen Liu, deputy chief physician, has completed laparotomy and minimally invasive laparoscopic surgery for more than 500 cases of CRC. He has rich experience in combined viscerectomy for locally advanced CRC and a profound understanding of membrane anatomy. He is quite accomplished in protecting patients’ sexual function and urination function when performing rectal cancer surgery. The surgeries were performed with the full advice and assistance of a multidisciplinary team. This study was approved by the ethics committee of Panzhihua Central Hospital (No. 20160001).
The following information of the patients was collected in detail: demographic aspects of the patients, American Society of Anesthesiologists (ASA) scores, duration of surgery, intraoperative blood loss, perioperative complications, pathological staging, and calculated overall survival and disease-free survival (DFS). Surgical risk was classified according to the ASA classification. Complications were classified according to the Clavien-Dindo classification[11 (link)]. The histopathological staging was recorded according to the tumor, nodes, metastases classification (American Joint Committee on Cancer 8th Edition for Cancer Staging).
Postoperatively, all patients were reevaluated by an oncologist to determine whether adjuvant therapy would be used. Five patients were in fair condition and underwent adjuvant chemotherapy (CAPOX, 12 wk), another two patients were not eligible for chemotherapy due to their cachexia, and four elderly patients in their 70 s gave up chemotherapy due to their elderly family members.

In case of surgical management, Roux-en-Y (R-Y) hepaticojejunostomy or duct-to-duct biliary reconstruction were performed. The duct-to-duct biliary reconstruction was favored in case of a long biliary duct given the “S”-shaped biliary duct in these cases, causing a “syphon effect”.

A standard OLT was defined as deceased donor transplantation of a standard criteria donor (SCD) whole organ after static cold storage (SCS) from a donation after brain death (DBD). The recipient hepatectomy was performed by retrohepatic caval resection without a veno-venous bypass, and the biliary anastomosis by duct-to-duct reconstruction. Deviations from this technique (e.g., split liver donation, extended criteria donation (ECD), donation after circulatory determination of death (DCD), the use of a veno-venous bypass, an inferior vena cava preservation by “piggyback” technique, or a Roux-en-y choledochojejunostomy) were recorded.
Extended criteria donors were defined according to the Eurotransplant Foundation rules by the following criteria: donor age >65 years, ICU stay with ventilation > 7 days, donor BMI > 30 kg/m2, hepatic steatosis > 40%, serum sodium > 165 mmol/L, alanine aminotransferase (ALT) > 105 U/L, aspartate aminotransferase (AST) > 90 U/L, total bilirubin > 3 mg/dL, and DCD [42 (link)].
Normothermic machine perfusion (NMP) was introduced at our center in February 2018 and has meanwhile been implemented in a daily routine for the following indications [43 (link)]:

Between 1984 and 2021, we performed choledochal cyst (CC) excision on 256 children at our center. Out of this group, we retrospectively reviewed the medical records of 59 patients operated on under one year of age. All of them underwent total cyst resection with end-to-side Roux-en-Y hepaticojejunostomy.
The open procedure was based on a right subcostal incision, total cyst resection, creation of a 40 cm length Roux-en-Y jejunal loop, and end-to-side hepaticojejunostomy. Since 2015, a laparoscopic approach for choledochal cyst resection has become our institution’s surgical method of choice. We used a 30° laparoscope introduced to the abdominal cavity through the umbilical incision and three ports of 3–5 mm (Figure 1 ). Transcutaneous traction sutures through the gallbladder and falciform ligament were used for better liver hilum exposure. A Roux-en-Y loop was created extra abdominally through the widened umbilical incision and returned to the abdomen. The end-to-side anastomosis was performed intraabdominally with interrupted monofilament absorbable 5/0 or 6/0 sutures (Figure 2 ).
All patients were followed postoperatively at 1, 3, 6 months, and every 12 months after surgery. Physical examination, liver function tests, and ultrasound examinations were retrospectively analyzed.
Standard demographic variables included age, gender, body weight, time of diagnosis, and presence of clinical symptoms during the preoperative period. We analyzed intraoperative, early, and late complications. The patients were subsequently divided into groups based on: the presence of symptoms in the preoperative period (asymptomatic vs. symptomatic), time of diagnosis (prenatal vs. postnatal), and surgical access (laparoscopy vs. laparotomy). We compared patients between groups for their demographic data, laboratory findings, and surgical outcomes. Complications were defined as early (<30 days after CC resection) or late (>30 days after CC resection).

More about "Roux-en-Y Anastomosis"
Roux-en-Y Anastomosis, also known as Roux-en-Y Gastric Bypass (RYGB), is a common surgical technique used to treat obesity and related conditions like type 2 diabetes.
This procedure involves creating a small stomach pouch and connecting it to the middle portion of the small intestine, bypassing the majority of the stomach and the first section of the small intestine.
The Roux-en-Y method helps improve nutrient absorption and promote weight loss by diverting the passage of food through a smaller stomach pouch.
This technique is often used in bariatric surgery, such as gastric bypass procedures.
The Orvil® device can be used to assist with the anastomosis, or connection, during the Roux-en-Y surgery.
