Effect of endoscopic full-thickness resection assisted by distal serosal turnover with floss traction for gastric submucosal masses

BACKGROUND Complex and high-risk surgical complications pose pressing challenges in the clinical implementation and advancement of endoscopic full-thickness resection (EFTR). Successful perforation repair under endoscopy, thereby avoiding surgical intervention and postoperative complications such as peritonitis, are pivotal for effective EFTR. AIM To investigate the effectiveness and safety of EFTR assisted by distal serosal inversion under floss traction in gastric submucosal tumors. METHODS A retrospective analysis of patients with gastric and duodenal submucosal tumors treated with EFTR assisted by the distal serosa inversion under dental floss traction from January 2023 to January 2024 was conducted. The total operation time, tumor dissection time, wound closure time, intraoperative bleeding volume, length of hospital stay and incidence of complications were analyzed. RESULTS There were 93 patients, aged 55.1 ± 12.1 years. Complete tumor resection was achieved in all cases, resulting in a 100% success rate. The average total operation time was 67.4 ± 27.0 min, with tumor dissection taking 43.6 ± 20.4 min. Wound closure times varied, with gastric body closure time of 24.5 ± 14.1 min and gastric fundus closure time of 16.6 ± 8.7 min, showing a significant difference (P < 0.05). Intraoperative blood loss was 2.3 ± 4.0 mL, and average length of hospital stay was 5.7 ± 1.9 d. There was no secondary perforation after suturing in all cases. The incidence of delayed bleeding was 2.2%, and the incidence of abdominal infection was 3.2%. No patient required other surgical intervention during and after the operation. CONCLUSION Distal serosal inversion under dental-floss-assisted EFTR significantly reduced wound closure time and intraoperative blood loss, making it a viable approach for gastric submucosal tumors.

Diagnosis and management of postpancreatectomy hemorrhage: A single-center experience of consecutive 1,096 pancreatoduodenectomies

Background/objectivesThis study aimed to assess the outcomes and characteristics of post-pancreatectomy hemorrhage (PPH) in over 1000 patients who underwent pancreatoduodenectomy (PD) at a high-volume hepatopancreaticobiliary center. MethodsThis retrospective study analyzed consecutive patients who underwent PD from 2010 through 2021. PPH was diagnosed and managed using our algorithm based on timing of onset and location of hemorrhage. ResultsOf 1096 patients who underwent PD, 33 patients (3.0%) had PPH; incidence of in-hospital and 90-day mortality relevant to PPH were one patient (3.0%) and zero patients, respectively. Early (≤24 h after surgery) and late (>24 h) PPH affected 9 patients and 24 patients, respectively; 16 patients experienced late-extraluminal PPH. The incidence of postoperative pancreatic fistula (p < 0.001), abdominal infection (p < 0.001), highest values of drain fluid amylase (DFA) within 3 days, and highest value of C-reactive protein (CRP) within 3 days after surgery (DFA: p < 0.001) (CRP: p = 0.010) were significantly higher in the late-extraluminal-PPH group. The highest values of DFA≥10000U/l (p = 0.022), CRP≥15 mg/dl (p < 0.001), and incidence of abdominal infection (p = 0.004) were identified as independent risk factors for PPH in the multivariate analysis. Although the hospital stay was significantly longer in the late-extraluminal-PPH group (p < 0.001), discharge to patient's home (p = 0.751) and readmission rate within 30-day (p = 0.765) and 90-day (p = 0.062) did not differ between groups. ConclusionsStandardized management of PPH according to the onset and source of hemorrhage minimizes the incidence of serious deterioration and mortality. High-risk patients with PPH can be predicted based on the DFA values, CRP levels, and incidence of abdominal infections.

The effects of ultrasound-guided radiofrequency ablation and laparoscopic hepatectomy in the treatment of small hepatocellular carcinoma: a retrospective analysis.

BackgroundHepatocellular carcinoma (HCC) is a commonly-seen cancer in the clinical setting. Laparoscopic hepatectomy (LH) and radiofrequency ablation (RFA) are used for the treatment of HCC, yet the effects and safety difference of LH and RFA for HCC treatment need further investigation.MethodsThis study was a retrospective study design. HCC patients treated with LH or RFA in our hospital were identified. All the patients underwent 2-year long follow-up. The characteristics and details of LH and RFA groups during hospitalization were collected and compared. The Kaplan-Meier method was used to calculate the cumulative survival, and the survival curve was drawn and compared.ResultsA total of 94 HCC patients were included. The duration of surgery, estimated intraoperative blood loss, pain score on the first day after surgery, time to get out of bed after operation, time to oral eating, aspartate transaminase (AST) on the second day after surgery, C-reactive protein (CRP) on the second day after surgery, total medical cost in RFA group were significantly less than that of LH group (all P<0.05). The incidence of abdominal infection and biliary fistula in RFA group were significantly less than that of LH group (all P<0.05), and there was no significant difference in the incidence of bleeding and pleural effusion between two groups (all P>0.05). The 2-year overall survival and recurrence-free survival of the two groups had no significant statistical difference (all P>0.05).ConclusionsRFA and LH have similar effects in the treatment of small HCC. And RFA has the advantages of less trauma, shorter operation duration, and quick postoperative recovery.

Clinical analysis of minimal invasive surgical treatment for pancreatic neuroendocrine tumors

Objective: To analyze the safety and effectiveness of minimal invasive surgery treating pancreatic neuroendocrine tumors (pNETs), and to summarize surgical characteristics and share experience. Methods: The clinical data of 80 pNETs treated by a single hospital from January 2015 to December 2019 were retrospectively analyzed. The patients were divided into laparoscopic group and robot group. And surgical procedures included pancreaticoduodenectomy (PD), distal pancreatectomy (DP), central pancreatectomy (CP), and tumor enucleation. Results: Of 80 patients, 76 cases (95%) underwent minimal invasive surgery and 4 cases (5%) changed to open surgery. There were 38 females, with median age of 54.4 (20-80) years and median BMI (17.0-38.0) kg/m(2). Among them, 24 patients (31.6%) underwent PD, 36 patients (47.4%) underwent DP, 8 patients (10.5%) underwent CP and 8 patients (10.5%) received tumor enucleation. The postoperative incidence of grade B/C pancreatic fistula was 35.5%, the incidence of abdominal infection was 10.5%, the postoperative bleeding was 7.9%, and the reoperation rate was 6.6%, without perioperative deaths. There was no significant difference in postoperative complications among different surgical methods, including postoperative pancreatic fistula (P=0.396), postoperative bleeding (P=0.297), postoperative abdominal infection (P=0.339) and reoperation (P=0.396). Conclusions: Surgical resection is an effective treatment for pNETs. pNETs are suitable for minimally invasive surgery with earlier stage and smaller tumor diameter. Minimally invasive surgery for pNETs is safe and feasible, and functional preserving surgery could take into consideration.

Clinical outcomes of preoperative endoscopic nasobiliary drainage versus percutaneous transhepatic biliary drainage for patients with perihilar cholangiocarcinoma

Objective To compare the clinical outcomes of endoscopic nasobiliary drainage (ENBD) versus percutaneous transhepatic biliary drainage (PTBD) in patients with perihilar cholangiocarcinoma. Methods This retrospective case-control study was conducted on 55 patients with perihilar cholangiocarcinoma who were treated by of hepatobiliary and pancreatic surgeons at the Nanjing Drum Tower Hospital between December 2010 and August 2017. Results There was no significant difference in the effectiveness of the two drainage methods (P>0.05). Morbidity after drainage was significantly higher in the ENBD group than the PTBD group (86.7% vs 28.0%, P 0.05). Abdominal infection after surgery was more common in the PTBD group than the ENBD group (64.3% vs 26.3%, P<0.05). Conclusion As PTBD caused catheter tract tumor implantation and increased the incidence of abdominal infection after surgery, ENBD was recommended for patients with perihilar cholangiocarcinoma treated in a tertiary medical center. Key words: Perihilar cholangiocarcinoma; Biliary drainage; Endoscopic nasobiliary drainage; Percutaneous transhepatic biliary drainage

Application of a glycaemic control optimization programme in patients with stress hyperglycaemia.

Stress-induced hyperglycaemia (SHG) can be observed in as high as 75% of critically ill patients, which can induce severe complications or adverse events. However, conventional intensive insulin therapy (CIIT) tends to induce hypoglycaemia and glucose variability. This study investigated the clinical effects of a blood glycaemic control optimization programme (BGCOP) in patients with stress hyperglycaemia post hepatobiliary or pancreatic surgery. This study is a randomized, controlled, prospective clinical observation. Eighty-six patients with postoperative SHG were randomly divided into a control and experimental groups. Participants in the control group underwent CIIT, while participants in the experimental group underwent blood glycaemic control optimization programme (BGCOP). A range of 7·8-10·0 mmol/L was designated as the target range for effective control of blood sugar. The validity index, adverse events and complications were compared between two groups. Compared to participants treated with CIIT, participants treated with BGCOP reached the target range of blood sugar levels more quickly (p = 0·000). The high glycaemic index (p = 0·000), incidence of hypoglycaemia (p = 0·011), and other adverse events as well as the incidence of abdominal infection (p = 0·026), incision infection (p = 0·044), and lung infection (p = 0·047) were significantly lower in participants who underwent the BGCOP than in patients treated with CIIT. BGCOP can more effectively control blood sugar levels compared with CIIT in patients with SHG after hepatobiliary or pancreatic surgery. This study provides a direction for blood glycaemic control in patients with stress hyperglycaemia post hepatobiliary or pancreatic surgery.

The utility of stapler in distal pancreatectomy

To determine the influence of hand-sewn and stapler in distal pancreatectomy on the postoperative complication. Clinical data of 109 patients after distal pancreatectomy from January 2003 to December 2006 were analyzed retrospectively. The surgical techniques used for closure of the pancreatic stump after distal pancreatectomy were categorized into hand-sewn closure group (n = 53) and stapler closure group (n = 56). In stapler closure group, 25 patients accepted laparoscopic operation. The incidences of abdominal infection and pancreatic fistulae in stapler closure group were lower than hand-sewn closure group. The operation time, blood infusion, postoperative bleeding and medical costs were similar between two groups. Stapler closure in distal pancreatectomy could decrease the incidence of pancreatic fistula and abdominal infections.
