OBJECTIVE: To investigate the clinical effect of transposition of gracilis muscle flap in repairing urethral perineal fistula after Miles operation. METHODS: The clinical data of 3 patients with urethral perineal fistula treated in the Second Affiliated Hospital of Zhejiang University from September 2023 to November 2024 were analyzed retrospectively. All patients were male, aged from 59 to 68 years (mean 63 years). All patients underwent Miles operation because of low rectal cancer. Urethral perineal fistula occurred after 2 months to 13 years of the operation. The underlying comorbidities included diabetes (2/3), preoperative chemoradiotherapy (1/3), and chemotherapy alone (1/3). The endourethral fistula was located in the apical and membranous part of the prostate, with a diameter of 1.5-2.0 cm and a mean of 1.7 cm. Suprapubic cystostomy was performed one month before operation. In all 3 cases, perineal inverted "Y" incision was taken under general anesthesia to expose urethral fistula, cut off necrotic tissue and suture urethral fistula. The gracilis muscle of the right thigh was taken and turned through the perineal subcutaneous tunnel. and 6 stitches were suture at the urethral fistula. RESULTS: The operations of all 3 patients were completed successfully. The follow-up period ranged from 2 months to 12 months, with an average of 8 months. There was no case of urinary incontinence after removal of catheter 3 weeks after operation. In two patients, urethrography was reviewed 1 month after surgery to show no fistula residue and urethral stenosis, and the fistula was removed. In one patient with a history of radiotherapy, urethrography was reviewed 1 month after surgery to show a small amount of contrast overflow around the urethra, and urethrography was reviewed again 3 months after surgery to show no contrast overflow around the urethra. All the 3 patients had no disturbance of movement of the right lower limb, and the pain of different degrees of thigh incision was acceptable and basically relieved half a month after operation. CONCLUSION Gracilis muscle flap is one of the effective methods for repairing urethral perineal fistula after Miles operation，which has a precise surgical result and few complications.

BACKGROUND

Gastric outlet obstruction (GOO) results from intrinsic and extrinsic obstruction of the pyloric channel or the duodenum. Here we present a rare case of GOO attributed to dense adhesions between the gallbladder and duodenum secondary to chronic cholecystitis with choledococystoduodenal fistula formation. Previous reports identified elderly females with comorbidities as a predisposing factor; however, our patient was an immunocompetent adult male.

A 43-year-old male with no comorbidities consulted for recurrent epigastric pain, vomiting and weight loss. On contrast enhanced abdominal CT scan, a lamellated cholelithiasis with pneumobilia and an irregular thickening at the proximal duodenum with subsequent GOO was identified. A choledococystoduodenal fistula was considered. Exploratory laparotomy revealed extensive fibrosis and cholecystitis with dense adhesions to surrounding structures. Dissection revealed a gallstone impacted in and adherent to the wall of the gallbladder and a fistula opening into the duodenum. However, there was no definite evidence of impacted gallstone in the duodenum. The dense adhesions secondary to chronic cholecystitis caused duodenal narrowing and subsequent GOO. He eventually underwent antrectomy, pancreatic sparing, total duodenectomy, cholecystectomy, with loop gastrojejunostomy, cholecystojejunostomy and pancreaticojejunostomy. Biopsy specimens taken were negative for malignancy. He was discharged subsequently. However, he was readmitted after five months due to acute abdomen secondary to small bowel rupture, likely from a marginal ulcer.

This case highlights that preoperative and intraoperative differential diagnosis of GOO is a challenge. Chronic calculous cholecystitis through severe inflammation can present as a rare cause of GOO. Optimal treasaFtment plan should take into consideration the underlying etiology of the GOO.

OBJECTIVE: To observe the effect of Dong's extraordinary point needling technique on postoperative complications of anal fistula. METHODS: A total of 241 patients undergoing anal fistula surgery were randomly divided into an observation group (121 cases, 3 cases dropped off) and a control group (120 cases, 2 cases dropped off). The patients in the control group were treated with intramuscular injection of compound diclofenac sodium injection and oral administration of tamsulosin hydrochloride sustained release capsules. In addition to the treatment in the control group, the patients in the observation group were treated with Daoma needling technique at the "Sanqi points" (Qimen point, Qijiao point, and Qizheng point) combined with Dongqi needling technique at "Sanhuang points" (sub-Tianhuang point, Dihuang point, Renhuang point), with each session lasting 30 min. The treatment in the two groups both started on the first day after surgery, and was given once daily for 14 consecutive days. Visual analog scale (VAS) score was compared between the two groups on postoperative day 1, 7, and 14; bladder residual urine volume, spontaneous voiding volume, and urinary catheterization frequency were assessed after treatment on postoperative day 1; and anorectal dynamic indexes (anal canal resting pressure, rectal resting pressure, maximum squeeze pressure of the anal canal, and minimum rectal sensory threshold) were evaluated before surgery and on postoperative day 4. Clinical efficacy was assessed in both groups one month after surgery. RESULTS: On postoperative day 7 and 14, the VAS scores of both groups were lower than those on postoperative day 1 (P<0.05), and the VAS scores in the observation group were lower than those in the control group (P<0.05). The bladder residual urine volume and urinary catheterization frequency in the observation group were lower than those in the control group (P<0.05), while the spontaneous voiding volume was higher than that in the control group (P<0.05). On postoperative day 4, the anal canal resting pressure, maximum squeeze pressure of the anal canal, and the minimum rectal sensory threshold were lower than preoperative values (P<0.05), while the rectal resting pressure was higher than preoperative value (P<0.05) in both groups. The anal canal resting pressure, maximum squeeze pressure of the anal canal, and minimum rectal sensory threshold were lower than those in the control group, and the rectal resting pressure was higher than that in the control group (P<0.05). The effective rate was 93.2% (110/118) in the observation group, which was higher than 84.7% (100/118) in the control group (P<0.05). CONCLUSION Dong's extraordinary point needling technique could reduce postoperative pain, alleviate urinary retention, and improve defecation in patients undergoing anal fistula surgery.

Objective: To investigate the safety and efficacy of embedding the stump of gastroduodenal artery between the left lateral lobe of the liver and the left caudate lobe to prevent bleeding after laparoscopic pancreaticoduodenectomy. Methods: The clinical data of 41 patients who underwent laparoscopic pancreaticoduodenectomy at the second Hospital of Hebei Medical University from October 2021 to April 2022 were analyzed retrospectively.There were 27 males and 14 females, aged (63.0±9.2)years (range: 48 to 78 years), and the body mass index was (24.1±3.2)kg/m² (range: 15.4 to 31.6 kg/m²). After routine laparoscopic pancreaticoduodenectomy, the stump of gastroduodenal artery was embedded between the left lateral lobe and the left caudate lobe of the liver, and the hepatic parenchyma of the left lateral lobe and the left caudate lobe were sutured with absorbable sutures.The occurrence and recovery of postoperative complications (pancreatic fistula, biliary fistula, postoperative abdominal bleeding, abdominal infection, liver abscess) were observed. Results: All the operations of 41 patients were completed successfully.The operation time was (277.5±52.0) minutes (range: 192 to 360 minutes). The entrapment time of gastroduodenal artery stump was (3.1±0.6) minutes (range: 2.3 to 4.2 minutes), and the intraoperative blood loss (M(IQR)) was 300 (200) ml (range: 50 to 800 ml).The results of ultrasound examination of hepatic artery on the first day after operation showed that the blood flows of hepatic artery were unobstructed.Postoperative pancreatic fistula occurred in 3 cases, including grade B pancreatic fistula in 2 cases (1 case with abdominal infection) and biochemical leakage in 1 case. Three patients with pancreatic fistula were discharged successfully after continuous abdominal drainage. There was no biliary fistula, abdominal bleeding, abdominal infection, liver abscess or postoperative liver dysfunction. Conclusion: The encasement of the gastroduodenal artery stump by the left outer and left caudate lobes of the liver may be an effective way to prevent bleeding from the rupture of the gastroduodenal artery stump after laparoscopic pancreatoduodenectomy, which is easy and safe to perform.

Open abdomen therapy is an effective treatment to deal with severe abdominal infections, abdominal hypertension and other critical abdominal diseases. However, this therapy is difficult to implement and has many uncertainties in the timing, manners, and follow-up treatment, which leads to the fact that open abdomen therapy is not very accessible and standardized in medical systems of China. This consensus aims to provide guiding principles for indications and implementation of open abdomen, classification methods of open abdomen wounds, technologies for abdominal closure, and management of enteroatmospheric fistula, so as to improve the accessibility and success rate of open abdomen in China.

Objective: To explore the development of the pancreatic surgeon technique in a high-volume center. Methods: A total of 284 cases receiving pancreatic surgery by a single surgeon from June 2015 to December 2020 were retrospectively included in this study. The clinical characteristics and perioperative medical history were extracted from the medical record system of Zhongshan Hospital,Fudan University. Among these patients,there were 140 males and 144 females with an age (M (IQR)) of 61.0 (16.8) years(range: 15 to 85 years). The "back-to-back" pancreatic- jejunal anastomosis procedure was used to anastomose the end of the pancreas stump and the jejunal wall. Thirty days after discharge,the patients were followed by outpatient follow-up or telephone interviews. The difference between categorical variables was analyzed by the Chi-square test or the CMH chi-square test. The statistical differences for the quantitative data were analyzed using one-way analysis of variance or Kruskal-Wallis H test and further analyzed using the LSD test or the Nemenyi test,respectively. Results: Intraoperative blood loss in pancreaticoduodenectomy between 2015 and 2020 were 300,100(100),100(100),100(0),100(200) and 150 (200) ml,respectively. Intraoperative blood loss in distal pancreatectomy was 250 (375),100 (50),50 (65), 50 (80),50 (50),and 50 (100) ml,respectively. Intraoperative blood loss did not show statistical differences in the same operative procedure between each year. The operative time for pancreaticoduodenectomy was respectively 4.5,5.0(2.0),5.5(0.8),5.0(1.3),5.0(3.3) and 5.0(1.0) hours in each year from 2015 to 2020,no statistical differences were found between each group. The operating time of the distal pancreatectomy was 3.8 (0.9),3.0 (1.5),3.0 (1.8),2.0 (1.1),2.0 (1.5) and 3.0(2.0) hours in each year,the operating time was obviously shorter in 2018 compared to 2015 (P=0.026) and 2020 (P=0.041). The median hospital stay in 2020 for distal pancreatectomy was 3 days shorter than that in 2019. The overall incidence of postoperative pancreatic fistula gradually decreased,with a incident rate of 50.0%,36.8%,31.0%,25.9%,21.1% and 14.8% in each year. During this period,in a total of 3,6,4,2,0 and 20 cases received laparoscopic operations in each year. The incidence of clinically relevant pancreatic fistula (grade B and C) gradually decreased,the incident rates were 0,4.8%,7.1%,3.4%,4.3% and 1.4%,respectively. Two cases had postoperative abdominal bleeding and received unscheduled reoperation. The overall rate of unscheduled reoperation was 0.7%. A patient died within 30 days after the operation and the overall perioperative mortality was 0.4%. Conclusion: The surgical training of a high-volume center can ensure a high starting point in the initial stage and steady progress of pancreatic surgeons,to ensure the safety of pancreatic surgery.

Postpancreatectomy acute pancreatitis (PPAP) is an acute inflammation of the remnant pancreas in the early postoperative period caused by a variety of factors. With the progress of related research,PPAP has been confirmed as an independent risk factor for many severe complications such as postoperative pancreatic fistula. In some cases, it progresses to necrotizing PPAP, increasing the risk of mortality. Currently, the International Study Group for Pancreatic Surgery has standardized and graded PPAP as an independent complication, taking into account factors including serum amylase, radiological features, and clinical impact. This review summarizes how the concept of PPAP was proposed, as well as the latest progress in the research related to its etiology, prognosis, prevention, and treatment. However, given the large heterogeneity of relevant studies and the fact that they were mostly retrospective, in the future, it is necessary to place more emphasis on PPAP and elucidate the problems through more standardized studies to optimize strategies for the prevention and management of complications after pancreatic surgery.

Surgery is the primary treatment for esophageal cancer, but the postoperative complication rate remains high. Therefore, it is important to prevent and manage postoperative complications to improve prognosis. Common perioperative complications of esophageal cancer include anastomotic leakage, gastrointestinal tracheal fistula, chylothorax, and recurrent laryngeal nerve injury. Respiratory and circulatory system complications, such as pulmonary infection, are also quite common. These surgery-related complications are independent risk factors for cardiopulmonary complications. Complications, such as long-term anastomotic stenosis, gastroesophageal reflux, and malnutrition are also common after esophageal cancer surgery. By effectively reducing postoperative complications, the morbidity and mortality of patients can be reduced, and their quality of life can be improved.
