Objectives: The blood supply of the transposed jejunum was assessed by ICG fluorescence imaging in jejunal interposition, and the correlation with anastomotic leakage or transposed jejunal necrosis was analyzed, aim to explore the value of the application ICG fluorescence imaging technology.
Methods: 84 esophageal reconstructions with jejunal interposition without supercharging were retrospectively analyzed. Intraoperatively, the blood supply of transposed jejunal was observed using ICG fluorescence endoscopy. ROC curve of T was constructed to calculate the corresponding T value of the region where the transposed jejunal want to be anastomosed with esophageal stump, the relationship between T value and anastomotic leakage or transposed jejunal necrosis was analyzed.
Results: The occurrence of anastomotic leakage and transposed jejunal necrosis was 9.5%, In the ROC curve, the maximum value of the Youden index was 0.691, the T value was 5.35 s. When T value > 5.35 s correspondingly, the probability of anastomotic leakage or transposition jejunal necrosis was 33.3% (7/21); when T value ≤ 5.35 s, the probability of anastomotic leakage or transposition jejunal necrosis was 1.6% (1/63). The difference between the two groups was statistically significant (P < 0.05).
Conclusion: ICG fluorescent imaging can effectively assess the blood supply of transposed jejunum. When T > 5.35, the possibility of the incidence rate of anastomotic leakage or transposed jejunum necrosis increases, this will remind the operators to take corresponding remedial measures during operation.

Risk Factors for Anastomotic Leakage: A Comprehensive Single-Center Analysis of Colorectal Anastomoses for Ovarian and Gastrointestinal Cancers.

Background: Anastomotic leakage (AL) is a major complication in colorectal surgery, particularly following rectal cancer surgery, necessitating effective prevention strategies. The increasing frequency of colorectal resections and anastomoses during cytoreductive surgery (CRS) for peritoneal carcinomatosis further complicates this issue owing to the diverse patient populations with varied tumor distributions and surgical complexities. This study aims to assess and compare AL incidence and associated risk factors across conventional colorectal cancer surgery (CRC), gastrointestinal CRS (GI-CRS), and ovarian CRS (OC-CRS), with a secondary focus on evaluating the role of protective ostomies.

The effective prevention and treatment of anastomotic leakage after intestinal anastomosis for colorectal diseases is still a major clinical challenge. In order to assist intestinal anastomosis healing and avoid anastomotic leakage caused by high tension, low blood supply or infection, we designed a double-layer nanofiber intestinal anastomosis scaffold, which was composed of electrospun PTMC/PHA nanofibers as the main layer, and electrospun PVA/OHA-Gs nanofibers with antibacterial properties as the antibacterial surface layer. This double-layer scaffold has good toughness, its maximum tensile force value could reach 8 N, elongation could reach 400 %, and it has hydrophilic properties, and its contact angle was about 60°.

Single versus double stapled anastomosis in natural orifice specimen extraction (NOSE) laparoscopic anterior resection.

Background: Laparoscopic anterior resection (LAR) with Natural Orifice Specimen Extraction (NOSE) has shown benefits such as reduced pain, fewer wound complications, and improved cosmesis. In colorectal anastomosis during NOSE, double staple anastomosis (DSA) and triple stapled technique (TSA) are common. However, a novel single stapled anastomosis (SSA) technique, utilising two laparoscopically placed purse strings and only four 5 mm ports, has emerged.

Acute kidney injury (AKI) is typically classified as prerenal, renal, or postrenal in etiology, with postrenal often referring to obstructive causes. However, certain uncommon conditions, such as intraperitoneal urinary leaks, may not fit clearly into these categories. In patients with a recent history of pelvic procedure, a complication such as intraperitoneal urinary leak can mimic AKI due to urine reabsorption across the peritoneum.
