Recently, the Department of General Surgery of our hospital successfully completed two cases of difficult laparoscopic key specialty techniques – laparoscopic middle pancreatic resection and laparoscopic total colorectal and anal canal resection. The two patients recovered well without any complications and were discharged from the hospital 7 and 8 days after surgery. This marks a new level of lumpectomy technology in general surgery of our hospital as a provincial clinical key specialty. The patient who underwent laparoscopic middle pancreatic resection in Chang Ren’an, Hepatobiliary Surgery Department of Nantong University Hospital, was a 44-year-old male who came to the hospital because of a cystic solid occupancy in the neck of the pancreas found in the physical examination of the unit. The patient and her family strongly wished to undergo minimally invasive surgical treatment so that she could return to work as soon as possible. The patient and his family strongly wished to undergo minimally invasive surgery so that he could return to work as soon as possible. After consulting with several tertiary hospitals in the province, the patient received the reply that “the tumor is adjacent to the splenic artery and splenic vein, so the surgery is risky and traditional open surgery is required”. The patient chose to seek help from the general surgery department of our hospital after making a lot of inquiries and checking the Internet for comparison. Professor Chen Zhong’s team decided to fully preserve the functional pancreas and spleen on the basis of complete resection of the lesion through 3D CT image reconstruction and simulated surgery demonstration. The laparoscopic exploration and surgical planning were perfectly matched, with the tumor adjacent to the splenic vessels posteriorly. The pancreas was delicately freed and a posterior pancreatic tunnel was established. Special instruments were used to dissociate the pancreas, and the middle pancreas containing the tumor was completely removed, the head of the pancreas was preserved, and the distal pancreas was successfully anastomosed with the jejunum, and the operation lasted 3 and a half hours, with only 150 ml of bleeding, and the patient was discharged one week after the operation. It is reported that this method lumpectively preserves the pancreatic head duodenum and the distal pancreas and spleen, which greatly improves the patient’s quality of life and also places higher demands on the surgical technique, because two pancreatic sections have to be dealt with to reduce the occurrence of pancreatic leakage. This technique has a high starting point and strict patient selection, which has not been reported in the central and northern Jiangsu region. The successful implementation of this operation in general surgery is another progress after laparoscopic liver resection, laparoscopic splenectomy and laparoscopic pancreatic body tail resection with preservation of spleen, which combines the use of laparoscopic techniques and virtual surgery, and is another result of the research on standardized diagnosis and treatment of provincial key diseases undertaken by our hospital. The patient who underwent laparoscopic total colorectal and anal canal resection was a 48-year-old male patient who was transferred to our hospital from Dongtai People’s Hospital because of long-term blood in the stool with abdominal pain. The colonoscopy suggested a malignant tumor 3 to 11 cm from the anus, and dozens of adenomatous polyps were diffusely and widely distributed in the entire colon. The patient’s mother also had a history of colon cancer. The patient was considered to have a rare case of “rectal cancer combined with total colorectal familial polyposis”. This disease is caused by a genetic mutation that causes multiple adenomas in the colon and involves the entire colorectum, which is prone to carcinogenesis. A multidisciplinary consultation was organized and concluded that colon polyps cannot be treated enteroscopically and that the lesions need to be removed as completely as possible. In China, total colon plus rectal anorectal resection is mostly performed by traditional open surgery with a long incision of at least 30 cm, which is very traumatic and bleeds a lot. Our team uses laparoscopic technique to perform right hemicolectomy, transverse colon, left hemicolectomy and rectal free. The scope of the operation is unique in abdominal surgery, and this is where the laparoscopic technique has the advantage of being able to achieve “ease of access” without opening the abdomen through four holes in the abdominal wall and long laparoscopic instruments. The last segment of the small intestine is dissected and the abdominal wall is enlarged with a poke hole to create a permanent artificial anus. The other team worked on the perineum to free the anal canal and use the perineal incision to remove the entire large intestine, avoiding the need for an abdominal incision to remove the specimen. The operation lasted for 8 hours and was supported by the strong anesthesia of Director Zhang Dexiang. According to Dr. Chang, the patient benefited greatly from this method compared to traditional open surgery, both economically and in terms of recovery from the disease. Traditional open surgery requires both left and right hemicolectomy and rectum during surgery, large abdominal incision, and large intra-abdominal organ disturbance, which can easily lead to complications such as incision infection, incision dehiscence, intestinal adhesion, and intestinal obstruction, and prolong patients’ hospital stay. The laparoscopic operation avoids the above-mentioned shortcomings, significantly shortens the hospitalization time due to the small injury and fast postoperative recovery, is conducive to the recovery of patient’s immunity, and is of great help to the comprehensive treatment of tumors. This technology as a national and provincial key specialty technology is also the pinnacle in the field of colorectal surgery. With the rising incidence of colorectal tumors, there is an urgent need for the continuous advancement of technology to benefit the majority of patients more. For this reason, the general surgery team sends its members to the United States, the United Kingdom and Germany every year to learn advanced technology and invite international authoritative experts to lecture, aiming at the standard of domestic first-class hospitals to build a medical service platform for the benefit of Jianghai people.
