Objective: To evaluate the influence of duodenal stump reinforcing on the short-term complications after laparoscopic radical gastrectomy. Methods: A retrospective cohort study with propensity score matching (PSM) was conducted. Clinical data of 1204 patients with gastric cancer who underwent laparoscopic radical gastrectomy at the First Affiliated Hospital of Army Medical University from April 2009 to December 2018 were collected. The digestive tract reconstruction methods included Billroth II anastomosis, Roux-en-Y anastomosis and un-cut-Roux- en-Y anastomosis. A linear stapler was used to transected the stomach and the duodenum. Among 1204 patients, 838 were males and 366 were females with mean age of (57.0±16.0) years. Duodenal stump was reinforced in 792 cases (reinforcement group) and unreinforced in 412 cases (non-reinforcement group). There were significant differences in resection range and anastomotic methods between the two groups (both P<0.001). The two groups were matched by propensity score according to the ratio of 1∶1, and the reinforcement group was further divided into purse string group and non-purse string group. The primary outcome was short-term postoperative complications (within one month after operation). Complications with Clavien-Dindo grade ≥ III a were defined as severe complications, and the morbidity of complication between the reinforcement group and the non-reinforcement group, as well as between the purse string group and the non-purse string group was compared. Results: After PSM, 411 pairs were included in the reinforcement group and the non-reinforcement group, and there were no significant differences in baseline data between the two groups (all P>0.05). No perioperative death occurred in any patient.The short-term morbidity of postoperative complication was 7.4% (61/822), including 14 cases of anastomotic leakage (23.0%), 11 cases of abdominal hemorrhage (18.0%), 8 cases of duodenal stump leakage (13.1%), 2 cases of incision dehiscence (3.3%), 6 cases of incision infection (9.8%) and 20 cases of abdominal infection (32.8%). Short-term postoperative complications were found in 25 patients (6.1%) and 36 patients (8.8%) in the reinforcement group and the non-reinforcement group, respectively, without significant difference (χ²=2.142, P=0.143). Nineteen patients (2.3%) developed short-term severe complications (Clavien-Dindo grade ≥IIIa), while no significant difference in severe complications was found between the two groups (1.7% vs. 2.9%, χ²=1.347, P=0.246). Sub-group analysis showed that the morbidity of short-term postoperative complication of the purse string group was 2.6% (9/345), which was lower than 24.2% (16/66) of the non-purse string group (χ²=45.388, P<0.001). Conclusion: Conventional reinforcement of duodenal stump does not significantly reduce the incidence of duodenal stump leakage, so it is necessary to choose whether to reinforce the duodenal stump individually, and purse string suture should be the first choice when decided to reinforce.

Objective: To examine the clinical effect of minimally invasive duodenum preserving pancreatic head resection(DPPHR) for benign and pre-malignant lesions of pancreatic head. Methods: The clinical data of patients with diagnosis of benign or pre-malignant pancreatic head tumor were retrospectively collected and analyzed,all of them underwent laparoscopic or robotic DPPHR between October 2015 and September 2021 at Division of Gastrointestinal and Pancreatic surgery,Zhejiang Provincial People's Hospital. Thirty-three patients were enrolled with 10 males and 23 females. The age(M(IQR)) was 54(32) years old(range: 11 to 77 years old) and the body mass index was 21.9(2.9)kg/m²(range: 18.1 to 30.1 kg/m²). The presenting symptoms included abdominal pain(n=12), Whipple triad(n=2), and asymptomatic(n=19). There were 7 patients with hypertension and 1 patient with diabetes mellitus. There were 19 patients who were diagnosed as American Society of Anesthesiologists class Ⅰ and 14 patients who were diagnosed as class Ⅱ. The student t test,U test, χ² test or Fisher exact test was used to compare continuous data or categorized data,respectively. All the perioperative data and metabolic morbidity were analyzed and experiences on minimally invasive DPPHR were concluded. Results: Fourteen patients underwent laparoscopic DPPHR,while the rest of 19 patients received robotic DPPHR. Indocyanine green fluorescence imaging was used in 19 patients to guide operation. Five patients were performed pancreatico-gastrostomy and the rest 28 patients underwent pancreaticojejunostomy. Pathological outcomes confirmed 9 solid pseudo-papillary neoplasms, 9 intraductal papillary mucinous neoplasms, 7 serous cystic neoplasms, 6 pancreatic neuroendocrine tumors, 1 mucous cystic neoplasm, 1 chronic pancreatitis. The operative time was (309.4±50.3) minutes(range:180 to 420 minutes),and the blood loss was (97.9±48.3)ml(range:20 to 200 ml). Eighteen patients suffered from postoperative complications,including 3 patients experienced severe complications(Clavien-Dindo Grade ≥Ⅲ). Pancreatic fistula occurred in 16 patients,including 8 patients with biochemical leak,7 patients with grade B pancreatic fistula and 1 patient with grade C pancreatic fistula. No one suffered from the duodenal necrosis and none perioperative death was occurred. The length of hospital stay was 14(7) days (range:6 to 87 days). The follow-up was 22.6(24.5)months(range:2 to 74 months). None suffered from recurrence or metastasis. During the follow-up,all the patients were free of refractory cholangitis. Moreover,in the term of endocrine dysfunction,no postoperative new onset of diabetes mellitus were observed in the long-term follow-up. However,in the view of exocrine insufficiency,pancreatic exocrine insufficiency and non-alcoholic fatty liver disease (NAFLD) was complicated in 2 and 1 patient,respectively,with the supplement of pancreatic enzyme,steatorrhea and weight loss relieved,but NAFLD was awaited to be seen. Conclusions: Minimally invasive DPPHR is feasible and safe for benign or pre-malignant lesions of pancreatic head. Moreover,it is oncological equivalent to pancreaticoduodenectomy with preservation of metabolic function without refractory cholangitis.

Single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) is simpler and has similar efficacy for obesity and obesity-associated metabolic diseases in comparison to biliopancreatic diversion with duodenal switch. We reported the first Da Vinci robot-assisted SADI-S in the treatment of severe obesity in China. This male patient was 27-year-old with height of 180 cm, body weight of 140 kg, waistline of 125 cm and body mass index of 43.2 kg/m(2). The diagnosis at admission was fatty liver, severe obesity, hypertriglyceridemia and hyperuricemia. The patient underwent Da Vinci robot-assisted SADI-S. The surgeon identified ileocecal part by appendix, then a common channel was measured retrogradely from the ileocecal valve, the distal ileum at 300 cm from the ileocecal part was marked and suspended. A sleeve gastrectomy was performed over a 34 Fr bougie tube. An end-to-side anastomosis between proximal duodenum and the pre-marked ileum was performed after duodenal bulb transection. Gastric incision was sutured with omentum reinforcement. No leakage was found after injecting methylene per os. Finally, a drainage tube was left in place under the anastomosis and close to the duodenal stump. The operation time was 244 minutes and the amount of bleeding during surgery was 50 ml. The patient recovered well with a postoperative hospital stay of 7 days and was followed up for six months. The percent of excess weight loss (EWL%) was 80.21% at 6 months after operation. The body weight, body mass index and waist circumference decreased significantly after operation. Complete remission was achieved for hypertriglyceridemia, hyperuricemia and insulin resistance. The patient suffered from cholestasis without serious complications at 6 months after operation. Our experience shows that Da Vinci robot-assisted SADI-S is safe and feasible in treating severe obesity.

Many individuals with short bowel syndrome (SBS) require long-term parenteral nutrition (PN) to maintain adequate nutritional status. Herein, we report a successful intestinal adaptation of a patient with SBS through 13 times intensive nutritional support team (NST) managements. A thirty-five-year-old woman who could not eat due to intestinal discontinuity visited Seoul National University Hospital for reconstruction of the bowel. She received laparoscopic Roux-en-Y gastric bypass (RYGB) due to morbid obesity in Jan 2013 at a certain hospital and successfully reduced her weight from 110 kg to 68 kg. However, after a delivery of the second baby by cesarean section in Jul 2016, most of small bowel was herniated through Peterson’s defect, and emergent massive small bowel resection was performed. Thereafter, she visited our hospital for the purpose of intestinal reconstruction. In Sep 2016, she received side–to-side gastrogastrostomy and revision of double barrel enterostomy. The remaining small bowel included whole duodenum, 30 cm of proximal jejunum, and 10 cm of terminal ileum. Pylorus and ileocecal valves were intact. The patient given only PN after surgery was provided rice-based soft fluid diet after 10 day of operation. Through intensive nutritional management care, she could start solid meals, and finally stop the PN and eat only orally at 45 days postoperatively. Three nutritional interventions were conducted over 2 months after the patient was discharged. She did not require PN during this period, and maintained her weight within the normal weight range. Similar interventions could be used for other patients with malabsorption problems similar to SBS.

Duodenal injury is a serious abdominal organ injury. Duodenal fistula is one of the most serious complications in gastrointestinal surgery, which is concerned for its critical status, difficulty in treatment and high mortality. Thoracic and abdominal compound closed injury and a small part of open injury are common causes of duodenal injury. Iatrogenic or traumatic injury, malnutrition, cancer, tuberculosis, Crohn's disease etc. are common causes of duodenal fistula, however, there has been still lacking of ideal diagnosis and treatment by now. The primary treatment strategy of duodenal fistula is to determine the cause of disease and its key point is prevention, including perioperative parenteral and enteral nutrition support, improvement of hypoproteinemia actively, avoidance of stump ischemia by excessive separate duodenum intraoperatively, performance of appropriate duodenum stump suture to ensure the stump blood supply, and avoidance of postoperative input loop obstruction, postoperative stump bleeding or hematoma etc. Once duodenal fistula occurs, a simple and reasonable operation can be selected and performed after fluid prohibition, parenteral and enteral nutrition, acid suppression, enzyme inhibition, anti-infective treatment and maintaining water salt electrolyte and acid-base balance. Double tube method, duodenal decompression and peritoneal drainage can reduce duodenal fistula-related complications, and then reduce the mortality, which can save the lives of patients.

Incidence of gastric cancer is high in China and standard radical operation is currently the main treatment for gastric cancer. Postoperative complications, especially some special complications, can directly affect the prognosis of patients, even result in the increase of mortality. But the incidences of these special complications are low, so these complications are often misdiagnosed and delayed in treatment owing to insufficient recognition of medical staff. These special complications include (1) Peterson hernia: It is an abdominal hernia developed in the space between Roux loop and transverse colon mesentery after Roux-Y reconstruction of digestive tract. Peterson hernia is rare and can quickly result in gangrenous ileus. Because of low incidence and without specific clinical symptoms, this hernia does not attract enough attention in clinical practice, so the outcome will be very serious. Once the diagnosis is made, an emergent operation must be performed immediately. Peterson space should be closed routinely in order to avoid the development of hernia. (2) Lymphatic leakage: It is also called chyle leakage. Cisterna chylus is formed by gradual concentration of extensive lymphatic net to diaphragm angle within abdominal cavity. Lymphadenectomy during operation may easily damage lymphatic net and result in leakage. The use of ultrasonic scalpel can decrease the risk of lymphatic leakage in certain degree. If lymphatic leakage is found during operation, transfixion should be performed in time. Treatment includes total parenteral nutrition, maintenance of internal environment, supplement of protein, and observation by clamp as an attempt. (3)Duodenal stump leakage: It is one of serious complications affecting the recovery and leading to death after subtotal gastrectomy. Correct management of duodenal stump during operation is one of key points of the prevention of duodenal stump leakage. Routine purse embedding of duodenal stump is recommend during operation. The key treatment of this complication is to promt diagnosis and effective hemostasis.(4) Blood supply disorder of Roux-Y intestinal loop: Main preventive principle of this complication is to pay attention to the blood supply of vascular arch in intestinal edge. (5) Anastomotic obstruction by big purse of jejunal stump: When Roux-en-Y anastomosis is performed after distal radical operation for gastric cancer, anvil is placed in the remnant stomach and anastomat from distal jejunal stump is placed to make gastrojejunal anastomosis, and the stump is closed with big purse embedding. The embedding jejunal stump may enter gastric cavity leading to internal hernia and anastomotic obstruction. We suggest that application of interruptable and interlocking suture and fixation of stump on the gastric wall can avoid the development of this complication.
