Background: With the improvement of anastomotic techniques and the iteration of anastomotic instruments, robotic intracorporeal suturing has become increasingly proficient. The era of fully intracorporeal anastomosis in robotic gastric cancer resection is emerging. This study aims to explore the impact of totally robotic distal gastrectomy (TRDG) and robotic-assisted distal gastrectomy (RADG) on patients' quality of life.

Patients and methods: This study is a comparative retrospective study of propensity score matching. This study included 306 patients who underwent robotic distal gastrectomy for gastric cancer between June 2016 and December 2023 at our center. Covariates used in the propensity score included sex, age, BMI, ASA score, maximum tumour diameter, degree of histological differentiation, Pathological TNM stage, Pathological T stage, Pathological N stage, and Lauren classification. Outcome measures included operative time, intraoperative bleeding, time to first venting, time to first fluid intake, postoperative hospital stay, total hospitalization cost, total length of abdominal incision, postoperative complications, inflammatory response, body image, and quality of life.

Results: According to the results of the study, compared with the RADG group, the TRDG group had a faster recovery time for gastrointestinal function (P = 0.025), shorter length of abdominal incision (P < 0.001), fewer days in the hospital (P = 0.006) less pain (P < 0.001), less need for additional analgesia (P = 0.013), and a postoperative white blood cell count (P < 0.001) and C-reactive protein content indexes were lower (P<0.001). In addition, the TRDG group had significantly better body imagery and cosmetic scores (P = 0.015), physical function (P = 0.039), role function (P = 0.046), and global function (P = 0.021) than the RARS group. Meanwhile, the TRDG group had milder symptoms of fatigue (P = 0.037) and pain (P < 0.001). The PASQ Total Subscale Score (P < 0.001) and Global Subscale Score (P < 0.001) were significantly lower in the TRDG group than in the RADG group at postoperative 3 months.

Conclusion: Totally robotic distal gastrectomy has a smaller incision, faster gastrointestinal recovery time, fewer days of postoperative hospitalization, and lower inflammatory markers than robotic-assisted distal gastrectomy. At the same time, postoperative cosmetic and quality of life outcomes were satisfactory. Clinically, these benefits translate to enhanced patient recovery, reduced surgical trauma, and better postoperative outcomes. These findings could guide surgeons in selecting more effective surgical approaches for patients undergoing gastrectomy, leading to better overall patient satisfaction and outcomes.

Background: Innovative attempt to explore the feasibility and accuracy of using indocyanine green fluorescence (ICGF) to identify the intersegmental plane by the target segmental veins preferential ligation during thoracoscopic segmentectomy.

Methods: A retrospective analysis was conducted on clinical data of 32 consecutive patients who underwent thoracoscopic segmentectomy with intersegmental plane identification using both ICGF and inflation-deflation method after target segmental veins prioritized blocking at Nanjing Chest Hospital from December 2022 to June 2023. Preoperative three-dimensional reconstruction was used to identify the target segment and the anatomical structure of the arteries, veins, and bronchi. After ligating the target segmental veins during surgery, the first intersegmental plane was immediately identified and marked with an electrocoagulation device using an inflation-deflation method. Subsequently, the second intersegmental plane was determined using the ICGF method. Finally, the consistency of the two intersegmental planes was evaluated.

Results: All the 32 patients successfully completed thoracoscopic segmentectomy without ICG-related complications and perioperative death. The average operation time was (98.59 ± 20.72) min, the average intraoperative blood loss was (45.31 ± 35.65) ml, and the average postoperative chest tube removal time was (3.5 ± 1.16) days. The average postoperative hospital stay was (4.66 ± 1.29) days, and the average tumor margin width was (26.96 ± 5.86) mm. The intersegmental plane determined by ICGF method was basically consistent with inflation-deflation method in all patients.

Conclusion: The ICGF can safely and accurately identify the intersegmental plane by target segmental veins preferential ligation during thoracoscopic segmentectomy, which is a beneficial exploration and important supplement to the simplified thoracoscopic anatomical segmentectomy.

Objective: The study aimed to examine the relationship between preoperative nutritional status, symptom burden, and the occurrence of postoperative atrial fibrillation in Esophageal Squamous Cell Carcinoma patients.

Methods: The study, conducted in the Department of Thoracic Surgery at the Affiliated Huai'an No. 1 People's Hospital of Nanjing Medical University, applied the NRS 2002, SGA and MSAS scoring systems as measures of nutritional status and symptom occurrence in patients diagnosed with ESCC. Univariate and multivariate logistic regression analysis were performed to evaluate the association between nutritional scores, symptom scores, and postoperative complications.

Results: The research found a significant correlation between high MSAS scores and postoperative atrial fibrillation. Patients with high symptom burden also tended to have nutritional risk or malnutrition according to the NRS2002 and SGA scores.

Conclusion: There is a need for healthcare providers to pay attention to ESCC patients' physical and psychological symptoms. Close monitoring of nutritional status and timely nutritional interventions should be integrated into these patients' care plans as they have been found to be related to postoperative complications such as atrial fibrillation.

Introduction: Colon cancer presents significant surgical challenges that necessitate the development of precise strategies. Standardization with complete mesocolic excision (CME) is common, but some cases require extended resections. This study investigates the use of 3D Image Processing and Reconstruction (3D-IPR) to improve diagnostic accuracy in locally advanced colon cancer (LACC) with suspected infiltration and achieve R0 surgery.

Methods: Single-center, prospective, observational, comparative, non-randomized study. •Participants: Patients aged > 18 years undergoing LACC surgery, as indicated by CT scans, confirmed via colonoscopy. Exclusion criteria include neoadjuvant therapy, suspected carcinomatosis on CT, and unresectable tumors. •Interventions: 3D-IPR models are used for surgical planning, providing detailed tumor and surrounding structure metrics. Surgical procedures are guided by CT scans and intraoperative findings, categorized by surgical margins as R0, R1, or R2. •Objective: The primary goal is to evaluate 3D-IPR's utility in achieving R0 resection in LACC with suspected infiltration. Secondary objectives include assessing preoperative surgical strategy, comparing CT reports, detecting adenopathy, and identifying vascularization and anatomical variants. • Outcome: The main outcome is the diagnostic accuracy of 3D-IPR in determining tumor infiltration of neighboring structures compared to conventional CT scans, using definitive pathological reports as the gold standard.

Results: •Recruitment and Number Analyzed: The study aims to recruit about 20 patients annually over two years, focusing on preoperative 3D-IPR analysis and subsequent surgical procedures. •Outcome Parameters: These include loco-regional and distant recurrence rates, peritoneal carcinomatosis, disease-free and overall survival, and mortality due to oncologic progression. •Harms: No additional risks from CT scans, as they are mandatory for staging colon tumors. 3D-IPR is derived from these CT scans.

Discussion: If successful, this study could provide an objective tool for precise tumor extension delimitation, aiding decision-making for radiologists, surgeons, and multidisciplinary teams. Enhanced staging through 3D-IPR may influence therapeutic strategies, reduce postsurgical complications, and improve the quality of life of patients with LACC.

Introduction: Acute pancreatitis (AP) is a common and potentially lethal disease. Approximately 10-20% of the patients progress to necrotizing pancreatitis (NP). The step-up approach is the gold standard approach to managing an infected necrotizing pancreatitis with acceptable morbidity and mortality rates. Video-assisted retroperitoneal debridement (VARD) has been described as a safe and feasible approach with high success rates. Multiple studies in the American, European, and Asian populations evaluating the outcomes of VARD have been published; nevertheless, outcomes in the Latin American population are unknown. This study aims to describe a single-center experience of VARD for necrotizing pancreatitis in Colombia with a long-term follow-up.

Methods: A prospective cohort study was conducted between 2016 and 2024. All patients over 18 years old who underwent VARD for necrotizing pancreatitis were included. Demographic, clinical variables, and postoperative outcomes at 30-day follow-up were described.

Results: A total of 12 patients were included. The mean age was 55.9 years old (SD 13.73). The median follow-up was 365 days (P25 60; P75 547). Bile origin was the most frequent cause of pancreatitis in 90.1% of the patients. The mean time between diagnosis and surgical management was 78.5 days (SD 22.93). The mean size of the collection was 10.5 cm (SD 3.51). There was no evidence of intraoperative complications. The mean in-hospital length of stay was 65.18 days (SD 26.46). One patient died in a 30-day follow-up. One patient presented an incisional hernia one year after surgery, and there was no evidence of endocrine insufficiency at the follow-up.

Conclusion: According to our data, the VARD procedure presents similar outcomes to those reported in the literature; a standardized procedure following the STEP-UP procedure minimizes the requirement of postoperative drainages. Long-term follow-up should be performed to rule out pancreatic insufficiency.

Background: The administration of antibiotic prophylaxis for clean-wound surgeries is controversial among surgeons, despite guidelines suggesting its use. This study aimed to evaluate its effectiveness in preventing surgical site infections (SSIs) in clean-wound surgeries within a regional setting with varied practices regarding prophylaxis.

Materials and methods: This retrospective cohort study included four types of common general surgeries performed from March 2021 to February 2023 at a tertiary regional hospital in Thailand. The surgeries included skin/subcutaneous excision, thyroidectomy, inguinal hernia repair, and breast surgeries, all of which required regional or general anesthesia. Antibiotic prophylaxis was administered at the discretion of the attending surgeons. SSI diagnosis followed standard diagnostic criteria, involving reviewing medical records and the records of the infection control unit. Infection risk factors were examined. The primary outcome comparison used inverse probability treatment weighting of propensity scores, with covariate balance evaluated.

Results: Of the 501 surgeries identified, 84 were excluded, leaving 417 eligible for analysis. Among these patients, 233 received prophylactic antibiotics, for an SSI rate of 1.3%, while 184 did not receive antibiotics, for an SSI rate of 2.2%. A comparative analysis using propensity score weighting revealed no statistically significant difference in the incidence of SSI between the groups (risk ratio [95% confidence interval]: 0.54 (0.11, 2.50), p = 0.427).

Conclusion: In this practical setting, with the given study size, antibiotic prophylaxis in common general surgeries involving clean wounds did not significantly prevent SSIs. Routine use recommendations should be re-evaluated.

Trial registration: Not applicable as this study is a retrospective cohort study and not a clinical trial.

Background: The relationship between postoperative cumulative systemic inflammation and cancer survival needs to be investigated. We developed an approach to the prognostication of postoperative esophageal cancer by establishing low and high cut-off values for the C-reactive protein (CRP) area under the curve (AUC) at 7 and 14 days after esophagectomy.

Methods: One hundred and twenty-five consecutive patients with biopsy-proven invasive esophageal squamous cell carcinoma (SCC) who underwent esophagectomies were evaluated. Postoperative CRP levels were analyzed for the first 14 days after surgery. The AUC on days 7 and 14 were calculated and compared with clinicopathological features and survival. The cut-off values for CRP at 7 days (CRP 7 d) and 14 days (CRP 14 d) were 599 mg/L and 1153 mg/L, respectively.

Results: The patients in the low CRP 7 d group had significantly better recurrence-free survival (RFS) and overall survival (OS), not that in the low CRP 14d group. The OS rates in the high CRP groups at PODs 1, 3, 10, and 14 were significantly lower than those in the low CRP groups. Postoperative complications were more common in the high CRP groups on PODs 3, 10, and 14. Univariate analyses revealed that pTNM stage, depth of tumor invasion, tumor location, lymph node involvement, and CRP 7 d were significant prognostic factors for both OS and RFS. The Cox proportional hazards model identified pTNM, tumor location, and CRP 7d as independent prognostic factors for the RFS and OS.

Conclusions: Early prediction of patients with postoperative complications, and adequate management will suppress the elevation of CRP 7 d and further suppress the CRP value in the late postoperative period, which may improve the prognosis of esophageal cancer patients after esophagectomy.

Background: The efficacy of Seprafilm^® in preventing clinically significant adhesive small bowel obstruction (ASBO) is controversial and deserves further review. The aim of this review was to assess the utility of Seprafilm^® in preventing clinically significant adhesive bowel obstruction after abdominal operations, with separate focus on colorectal resections. The secondary aim was to provide an updated literature review on the safety profile of this implant.

Methods: An up-to-date systematic review was performed on the available literature between 2000 and 2023 on PubMed, EMBASE, Medline, and Cochrane Library databases. The main outcome measures were rates of adhesive bowel obstruction, as well as rates of intervention. The secondary outcome was the clinical safety profile of Seprafilm^® as described in current literature.

Results: A total of 17 observational studies were included, accounting for 62,886 patients. Use of Seprafilm^® was associated with a significant reduction in adhesive bowel obstruction events (OR 0.449, 95% CI: 0.3271 to 0.6122, p < 0.001), with preserved efficacy seen in laparoscopic cases. This did not translate into a reduced rate of reintervention. Clinicians should also be aware of isolated reports of a paradoxical inflammatory reaction leading to fluid collections after Seprafilm^® use, although they appear uncommon.

Conclusion: Seprafilm^® can be considered in select patients although further study to determine which patients will benefit most is required.

Background: Pancreaticoduodenectomy is a highly difficult and invasive type of gastrointestinal surgery. Prevention of postoperative pancreatic fistula is important, and this may be possible by the stapler method.

Methods: STRAP-PD is a single center randomized controlled trial. We compare a method of transecting the pancreatic parenchyma in pancreaticoduodenectomy using a surgical stapler device with a conventional transecting method using energy devices (e.g., scalpel, ultrasonic coagulator and incision devices). Patients with soft pancreas who are scheduled to undergo pancreaticoduodenectomy are randomized to arm A (conventional method) or arm B (stapler method). We aim to examine the safety and usefulness of dissection by the automatic suture device, with attention to the rate of pancreatic fistula ISGPF grade B or C and to postoperative complications. This is a single-center randomized study, which began in September 2023 at Wakayama Medical University Hospital.

Discussion: Pancreatic parenchymal transection is typically performed either by direct incision using a scalpel or by employing energy devices such as ultrasonic coagulating cutting devices during pancreaticoduodenectomy. In a prospective pilot study, we conducted pancreatic parenchymal transection in 20 consecutive normal pancreatic cases during pancreaticoduodenectomy, observing postoperative pancreatic fistula grade B in one case (5%). Traditional methods involving scalpel incision or the use of ultrasonic coagulating cutting devices have been historically favored but perceived as technically challenging, and they have been reliant upon the surgeon's skill. Notably, relatively high incidences of postoperative pancreatic fistula among patients with soft pancreas have also been observed. Our proposed stapler method may therefore be a useful method responsible for reducing the development of pancreatic fistula. This method would be as part of minimally-invasive surgery for pancreaticoduodenectomy. It uses an endoscopic linear stapler to cut the pancreatic parenchyma, so it is likely to be more convenient than conventional methods and can be used universally.
