Objective: To investigate the feasibility and short-term outcomes of total laparoscopic sigmoid and rectal surgery combined with transanal endoscopic microsurgery(TEM).
Methods: The clinical data of 26 patients with colorectal carcinoma treated by total laparoscopic surgery with TEM between May 2010 and May 2011 in the Shanghai Ruijin Hospital were retrospectively analyzed.
Results: All the 26 operations were successfully accomplished laparoscopically. There was no conversion to open procedure. No diverting ileostomy was made. The mean operative time was (151.6±25.9) min. The mean blood loss was (200.2±114.7) ml. The mean time to first flatus was (2.0±0.5) d. The mean tumor size was (3.0±0.7) cm and all resection margins were negative. The mean number of lymph nodes harvested was (12.9±2.2). Six patients developed postoperative anastomotic leakage, all of who had tumors in the lower rectum. There were no ureteral injury, intestinal obstruction, or pulmonary infection.
Conclusions: Total laparoscopic sigmoid and rectal surgery combined with TEM is a safe and feasible minimally invasive surgery. It is an improvement by combining laparoscopic skills with the concept of natural orifice transluminal endoscopic surgery.

Laparoscopic liver resection (LLR) is a minimally invasive surgical approach. Initially utilized for low-risk procedures, such as the resection of benign lesions, now LLR has evolved to include more complex operations such as metastatic lesions. We present in this article two cases with liver metastasis who underwent a successful two-stage total LLR: a 57-year-old man diagnosed with sigmoid cancer and liver metastasis and a 36-year-old man diagnosed with pancreatic neuroendocrine tumor and liver metastasis.

Background: Devices that help educate young doctors and enable safe, minimally invasive surgery are needed. Eureka is a surgical artificial intelligence (AI) system that can intraoperatively highlight loose connective tissues (LCTs) in the dissected layers and nerves in the surgical field displayed on a monitor. In this study, we examined whether AI navigation (AIN) with Eureka can assist trainees in recognizing nerves during colorectal surgery.

Sciatic hernia, a rare type of pelvic floor hernia, presents significant diagnostic and therapeutic challenges. We report the first totally extraperitoneal (TEP) repair of a sciatic hernia, which was performed in a 63-year-old woman who presented with vomiting and poor dietary intake. Computed tomography revealed a strangulated femoral hernia and an incidental herniation of the sigmoid colon through the right sciatic foramen.

It is well established that host immunity plays a critical role in defending against colorectal cancer (CRC) progression. Connective tissue disease (CTD) encompasses a group of heterogeneous, immune-mediated disorders that present with diverse and often non-specific initial symptoms. Raynaud's phenomenon is a common feature, complicating early diagnosis.
