OBJECTIVES
Synchronous adenomas of the major and minor duodenal papilla are seldom reported. The aim of this study was to describe the characteristics of synchronous major and minor papilla adenomas and to evaluate the safety and efficacy of endoscopic papillectomy (EP) for the management of the disease.
METHODS
Consecutive patients who underwent endoscopy for synchronous major and minor papilla adenomas from January 1, 2013 to August 31, 2023 were analyzed retrospectively. Patients' characteristics, clinical manifestations, laboratory, imaging and endoscopic findings were collected.
RESULTS
The nine patients with synchronous major and minor papilla adenomas had an average age of 50.78 ± 10.70 years. The diameter of major and minor papilla adenomas was 12.11 ± 3.41 mm and 6.11 ± 1.05 mm, respectively. Most major papilla adenomas had R0 horizontal margins (n = 8), while R0 vertical margins were achieved in all patients. While minor papilla adenomas were resected with both R0 horizontal and vertical margins in all patients. Post-EP bleeding was observed in one patient, which was classified as mild. Post-EP hyperamylasemia and pancreatitis was observed in two and four patients, respectively; the latter consisted of three with mild pancreatitis and one with severe pancreatitis. No perforation was observed. The mean follow-up duration was 9.22 ± 5.99 months. Histologically confirmed recurrence at the resection site was detected in one patient at 3 months after the procedure.
CONCLUSIONS
Synchronous major and minor papilla adenomas may not be as rare as previously speculated. EP may be an effective and safe alternative modality for their management.

Review
Gastrojejunostomy is the principal method of palliation for unresectable malignant gastric outlet obstructions (GOO). Gastrojejunostomy was traditionally performed as a surgical procedure with an open approach butrecently, notable progress in the development of minimally invasive procedures such as laparoscopic gastrojejunostomies have emerged. Additionally, advancements in endoscopic techniques, including endoscopic stenting (ES) and endoscopic ultrasound-guided gastroenterostomy (EUS-GE), are becoming more prominent. ES involves the placement of self-expandable metal stents (SEMS) to restore luminal patency. ES is commonly the first choice for patients deemed unfit for surgery or at high surgical risk. However, although ES leads to rapid improvement of symptoms, it carries limitations like higher stent dysfunction rates and the need for frequent re-interventions. Recently, EUS-GE has emerged as a potential alternative, combining the minimally invasive nature of the endoscopic approach with the long-lasting effects of a gastrojejunostomy. Having reviewed the advantages and disadvantages of these different techniques, this article aims to provide a comprehensive review regarding the management of unresectable malignant GOO.

Journal of Medical Case Reports Apr 2024Postoperative delayed bleeding of gastric cancer is a complication of radical gastrectomy with low incidence rate and high mortality.
BACKGROUND
Postoperative delayed bleeding of gastric cancer is a complication of radical gastrectomy with low incidence rate and high mortality.
CASE PRESENTATION
This case report presents the case of a 63-year-old female patient of Mongolian ethnicity who was diagnosed with gastric malignancy during a routine medical examination and underwent Billroth's I gastric resection in our department. However, on the 24th day after the surgery, she was readmitted due to sudden onset of hematemesis. Gastroscopy, abdominal CT, and digital subtraction angiography revealed postoperative anastomotic fistula, rupture of the duodenal artery, and bleeding from the abdominal aorta. The patient underwent three surgical interventions and two arterial embolizations. The patient's condition stabilized, and she was discharged successfully.
CONCLUSION
Currently, there are no specific guidelines for the diagnosis and treatment of pseudoaneurysms in the abdominal cavity resulting from gastric cancer surgery. Early digital subtraction angiography examination should be performed to assist in formulating treatment plans. Early diagnosis and treatment contribute to an improved overall success rate of rescue interventions.

OBJECTIVE
This study introduced the modified Q-type purse-string suture duodenal stump embedding method, a convenient way to strengthen the duodenum, and compared it to the conventional one to assess its efficacy and safety.
METHODS
This retrospective analysis examined 612 patients who received laparoscopic gastrectomy for gastric Cancer at a single center. The patients were divided into Not Reinforced Group (n = 205) and Reinforced Group (n = 407) according to the surgical approach to the duodenal stump. The reinforced group was further divided into a modified Q-type purse-string suture embedding method group (QM, n = 232) and a conventional suture duodenal stump embedding method group (CM, n = 175) according to the methods of duodenal stump enhancement. Clinicopathological characteristics, operative variables, and short-term complications were documented and analyzed.
RESULTS
The incidence of duodenal stump leakage(DSL) in the Not Reinforced Group was higher compared to the Reinforced Group, although the difference was not statistically significant [2.4% (5/205) vs 0.7% (3/407), p = 0.339]. Additionally, the Not Reinforced Group exhibited a higher rate of Reoperation due to DSL compared to the Reinforced Group [2 (1.0%) vs. 0, p = 0.046], with one patient in the Not Reinforced Group experiencing mortality due to DSL [1 (0.5%) vs 0, p = 0.158]. Subgroup analysis within the Reinforced Group revealed that the modified Q-type purse-string suture embedding group (QM) subgroup demonstrated statistically significant advantages over the conventional suture embedding group (CM) subgroup. QM exhibited shorter purse-string closure times (4.11 ± 1.840 vs. 6.05 ± 1.577, p = 0.001), higher purse-string closure success rates (93.1% vs. 77.7%, p = 0.001), and greater satisfaction with purse-string closure [224 (96.6%) vs 157 (89.7%), p = 0.005]. No occurrences of duodenal stump leakage were observed in the QM subgroup, while the CM subgroup experienced two cases [2 (1.1%)], though the difference was not statistically significant. Both groups did not exhibit statistically significant differences in secondary surgery or mortality related to duodenal stump leakage.
CONCLUSION
Duodenal Stump Leakage (DSL) is a severe but low-incidence complication. There is no statistically significant relationship between the reinforcement of the duodenal stump and the incidence of DSL. However, laparoscopic reinforcement of the duodenal stump can reduce the severity of fistulas and the probability of Reoperation. The laparoscopic Q-type purse-string suture duodenal stump embedding method is a simple and effective technique that can, to some extent, shorten the operation time and enhance satisfaction with purse-string closure. There is a trend towards reducing the incidence of DSL, thereby improving patient prognosis to a certain extent.

BACKGROUND
The detection rate of superficial non-ampullary duodenal epithelial tumors (SNADETs) has recently been increasing. Large tumors may contain malignant lesions and early therapeutic intervention is recommended. Endoscopic mucosal dissection (ESD) is considered a feasible treatment modality, however, the anatomical and physiological characteristics of the duodenum create a risk of postoperative perforation after ESD.
METHODS
To explore whether myoblast sheet transplantation could prevent delayed perforation after ESD, a first-in-human (FIH) clinical trial of laparoscopic autologous myoblast sheet transplantation after duodenal ESD was launched. Autologous myoblast sheets fabricated from muscle tissue obtained seven weeks before ESD were transplanted laparoscopically onto the serous side of the ESD. The primary endpoints were the onset of peritonitis due to delayed perforation within three days after surgery and all adverse events during the follow-up period.
RESULTS
Three patients with SNADETs ≥ 20 mm in size underwent transplantation of a myoblast sheet onto the serous side of the duodenum after ESD. In case 1, The patient's postoperative course was uneventful. Endoscopy and abdominal computed tomography revealed no signs of delayed perforation. Despite incomplete mucosal closure in case 2, and multiple micro perforations during ESD in case 3, cell sheet transplantation could prevent the postoperative massive perforation after ESD, and endoscopy on day 49 after transplantation revealed no stenosis.
CONCLUSIONS
This clinical trial showed the safety, efficacy, and procedural operability of this novel regenerative medicine approach involving transplanting an autologous myoblast sheet laparoscopically onto the serosa after ESD in cases with a high risk of delayed perforation. This result indicates the potential application of cell sheet medicine in treating various abdominal organs and conditions with minimal invasiveness in the future.

The clinical data of 7 patients diagnosed with mixed neuroendocrine-nonneuroendocrine neoplasm were analyzed in the Department of Hepatobiliary Surgery of Hunan Provincial People's Hospital from January 2016 to December 2022. Among the 7 patients, 5 were male and 2 were female, with an average age of 59.3 years. Its clinical characteristics are similar to malignant ampulla tumors, and it is difficult to differentiate them. The preoperative puncture biopsy positivity rate is low, making it difficult to diagnose preoperatively, and the prognosis is worse.Comprehensive treatment including surgery, chemotherapy, and radiotherapy can be the preferred treatment option for this disease.

To explore the efficacy and safety of laparoscopic radical gastrectomy after neoadjuvant chemotherapy combined with immunotherapy and targeted therapy in patients with gastric cancer. A retrospective analysis of clinical and pathological data of 20 patients with locally advanced gastric cancer (clinical TNM stage T3-4aN+M0) admitted to the Cancer Hospital, Chinese Academy of Medical Sciences from July 2021 to July 2023. All patients received 3 cycles of SOX (Oxaliplatin+S-1) regimen combined with immunotherapy (Trastuzumab) and targeted therapy (Apatinib) as neoadjuvant treatment followed by laparoscopic radical gastrectomy for gastric cancer. Surgical outcomes, postoperative pathological response, and postoperative recovery were observed. Quantitative data, except for age and operation time, were expressed using Median (range). Among the 20 patients, there were 18 males and 2 females, aged 41 to 73 years [(60.6±9.7) years]. All 20 patients underwent laparoscopic surgical treatment after neoadjuvant therapy, with one patient undergoing laparoscopic conversion to open total gastrectomy with partial transverse colon resection due to tumor invasion into the transverse mesocolon. Eight patients underwent totally laparoscopic radical gastrectomy, all with Billroth Ⅱ+Braun anastomosis at the distal stomach. Eleven patients underwent laparoscopic-assisted radical gastrectomy, among which total gastrectomy with Roux-en-Y anastomosis was performed in ten cases, and proximal gastrectomy with esophagogastrostomy overlap anastomosis was performed in one case. The mean operation time for the 20 patients was (165.0±34.1) minutes; intraoperative blood loss was 80 (20-100) ml; and the number of lymph nodes retrieved was 68 (21-89). Postoperative pathological TNM staging revealed stage T0N0M0 in six cases, stage Ⅰ in two cases, stage Ⅱ in three cases, and stage Ⅲ in nine cases. Six patients (30.0%) achieved pathological complete response, and nine patients (45.0%) achieved significant pathological response. The median postoperative time to flatus was 4 (1-5) days; oral intake resumed after 3 (2-5) days; and the median length of hospital stay was 13 (6-19) days. One patient developed colonic anastomotic leakage with intra-abdominal infection, and one patient developed duodenal stump leakage with intra-abdominal infection, both classified as Clavien-Dindo grade 3A complications, and improved after treatment and discharged. One patient developed gastric paresis, and two patients developed pleural effusion, classified as Clavien-Dindo grade 2 complications, and improved after treatment and discharged. There were no deaths within 30 days after discharge. Laparoscopic radical gastrectomy for gastric cancer after neoadjuvant treatment with the SOX regimen combined with immunotherapy and targeted therapy is safe and feasible, with satisfactory short-term efficacy. However, there is an increase in overall surgical risk and difficulty, and it is recommended to be performed in experienced gastric cancer centers.

BACKGROUND
Pancreaticoduodenectomy has been the standard of care for managing duodenal neoplasms, but recent studies show similar overall and disease-specific survival after pancreas-preserving duodenectomy (PPrD) with potentially less morbidity.
METHODS
Retrospective cohort of all adult (age >18) patients who underwent PPrD with curative intent of a neoplasm in or invading into the duodenum at our institution from 2011 to 2022 (n = 29), excluding tumors involving the Ampulla of Vater or the pancreas. Statistical analyses were performed using STATA.
RESULTS
R0 resection was achieved in 93 % patients. Ten (34.4 %) experienced postoperative complications (13.7 % within Clavien-Dindo III-V). PPrD patients had lower rates of pancreatic leak, delayed gastric emptying, and deep surgical site infection.
CONCLUSIONS
In this case series, we demonstrate PPrD is safe and effective, with a high rate of complete resection and lower complication rate than that seen in pancreaticoduodenectomy.

KEY CLINICAL MESSAGE
Duodenal GISTs are rare and challenging tumors. Acute life-threatening upper GI bleeding is a possible presentation of duodenal GISTs. Surgery is the standard treatment for localized duodenal GISTs. Imatinib is an effective adjuvant therapy for duodenal GISTs.
ABSTRACT
GIST is the most common mesenchymal neoplasm of the gastrointestinal tract, accounting for 1%-2% of gastrointestinal tumors. They originate from the interstitial cells of Cajal and are rare in patients younger than 30 years. The stomach is the most common site, followed by the small intestine and colon. GISTs are caused by a gain-of-function mutation in the proto-oncogene receptor tyrosine kinase, with activating mutations in KIT being the most common. Most GISTs are asymptomatic. Even if gastrointestinal bleeding is the most common complication life-threatening hemorrhage is extremely uncommon. We present a case of a 31-year-old male patient presented with massive active hematemesis and melena with hemorrhagic shock. The patient presented with massive hematemesis and melena of 1 h duration. Endoscopy showed pulsating active bleeding from the third part of the duodenum which was difficult to manage via endoscopy. Histopathologic evaluation showed spindle cell type GIST. Intraoperatively, there was a nodular mass with active bleeding on the third part of the duodenum. Duodenectomy with end-to-end anastomosis was done. Discharged with no postoperative complication and was put on imatinib. There are considerable challenges that arise in the diagnosis and treatment of duodenal gastrointestinal stromal tumors (GISTs) when they present with life-threatening upper gastrointestinal hemorrhage. In order to achieve the best possible outcomes for patients, it is crucial to have a comprehensive understanding of the clinical presentation, diagnostic methods, and treatment approaches.
