Abstract: The synchronous occurrence of pancreatic neuroendocrine neoplasm (PNEN) and clear cell renal cell carcinoma (ccRCC) in one patient is extremely rare. Synchronous resection of both tumours is preferred over a two-stage procedure if possible. The robotic da Vinci Xi platform allows for multi-quadrant surgery with oncological outcomes comparable to those of laparoscopic or open surgery. We present the case report of an 80-year-old male who underwent synchronous resection of a PNEN in the tail of the pancreas and ccRCC in the left kidney. To the best of our knowledge, this is the first case report on this topic.

Abstract: Technical difficulties are often encountered in a laparoscopic cholecystectomy where a tense/distended/ turgid gall bladder prevents the surgeon from grasping the gall bladder properly which therefore necessitates the decompression of the turgid gall bladder. However, even if intraoperative decompression is done, the spillage of remnant stones, bile or fluid from the gall bladder is a possibility which can lead to undue complications. This is where following the simple technique of using a gauze piece with a radio-opaque marker to occlude the decompression puncture site helps in performing a safe decompression thereby preventing bile, fluid or stone spillage.

Introduction: Uniportal video-assisted thoracoscopic surgery (Uni-VATS) is an effective minimally invasive technique for pericardial drainage, biopsy and window creation in cases of pericardial effusion (PE).

Patients and methods: This retrospective study evaluated 73 patients with PE who underwent pericardial window procedures between 2012 and 2024. Intraoperative and post-operative data related to Uni-VATS were assessed.

Results: The mean age of the patients was 53.79 ± 17.79 years (10-82 years), with 34 (46.6%) females and 39 (53.4%) males. The mean volume of pericardial fluid drained after window creation was 446.23 ± 199.81 cc (75-1100 cc). The mean operation time was 42.87 ± 12.79 min, and chest drain removal occurred after an average of 1.8 ± 1.2 days. The mean duration until discharge or referral to the follow-up clinic was 5.98 ± 2.14 days. In addition to the pericardial window procedure, pleural biopsy was performed in 12 patients, mediastinal mass biopsy in eight patients and wedge resection for parenchymal nodules in six patients. Microbiologic and virologic cultures of the fluids were negative in all cases. Among the 41 patients with benign cytology, pericardial biopsy results indicated tuberculosis in four patients (5.4%), amyloidosis in one patient (1.3%) and chronic or subacute nonspecific pericarditis in the remaining patients.

Conclusion: Uni-VATS is a novel and safe technique that may be the preferred choice for pericardial window due to its diagnostic and therapeutic efficacy, ability to perform simultaneous procedures, favourable impact on operation duration/hospital stay, low complication rates and superiority compared to traditional methods.

Introduction: Post-operative pulmonary complications (PPCs) are a significant cause of morbidity following surgery. This study evaluated the effect of intraoperative positive end-expiratory pressure (PEEP) on PPCs in overweight patients undergoing elective laparoscopic hernia surgery.

Patients and methods: In this randomised controlled trial, 60 patients with a body mass index between 25 and 30 kg/m² were divided equally into a standard PEEP group (5 cm H2O) and a high PEEP group (10 cm H2O). The primary outcome was the incidence of PPCs, with secondary outcomes assessing intraoperative respiratory mechanics, haemodynamics and post-operative oxygenation levels.

Results: Both groups demonstrated comparable demographic and baseline characteristics. The results showed a significant reduction in the incidence of PPCs in the high PEEP group, with atelectasis observed in 16% of control patients versus 6% of those receiving higher PEEP. In addition, the high PEEP group exhibited improved dynamic lung compliance and oxygenation but had an increased mean arterial pressure, indicating haemodynamic effects associated with higher PEEP levels. While the Cabrini Respiratory Strain Score and air test scores were comparable, patients in the high PEEP group had shorter durations of supplemental oxygen therapy and improved post-operative oxygenation at 6, 12 and 24 h.

Conclusion: These findings suggest that high PEEP may enhance lung mechanics and oxygenation while reducing PPCs in overweight patients, although careful monitoring of haemodynamic stability is recommended.

Background: We aimed to assess the therapeutic effects of single-port thoracoscopic anatomical segmentectomy on early-stage non-small-cell lung cancer (NSCLC).

Patients and methods: Sixty patients with early-stage NSCLC admitted from December 2022 to July 2023 were selected and divided into a lobectomy group ( n = 30) and a segmentectomy group ( n = 30) according to the different procedures. Their perioperative indicators, pre-operative and post-operative pulmonary function indicators, pain degree 24 h, 48 h, 72 h and 7 day after operation, the incidence of post-operative complications and recurrence, survival and mortality rates 1 year after operation were compared.

Results: The segmentectomy group had significantly smaller intraoperative blood loss, shorter length of drainage and length of hospital stay and longer operation time than those of the lobectomy group ( P < 0.05). The pulmonary function decreased significantly in both groups 1 week, 1 month and 3 months after operation. Compared with the lobectomy group, the forced expiratory volume in 1 s per cent, forced-vital capacity per cent and maximal voluntary ventilation of the segmentectomy group significantly increased at each time point after operation ( P < 0.05). The Visual Analogue Scale scores 24 h, 48 h, 72 h and 7 days after operation were significantly lower in the segmentectomy group than those in the lobectomy group ( P < 0.05). There were no significant differences in the incidence of post-operative complications and recurrence, survival and mortality rates 1 year after operation between the two groups ( P > 0.05).

Conclusions: Single-port thoracoscopic anatomical segmentectomy has obvious therapeutic effects on early-stage NSCLC, characterised by smaller surgical trauma, milder post-operative pain and less impact on pulmonary function.

Abstract: Common bile duct (CBD) stones are usually caused by biliary tract infection, biliary stricture, duodenal peripapillary diverticulum, Oddis sphincter dysfunction, and so on. Treatment is preferably with endoscopic retrograde cholangiopancreatography (ERCP), where an iodine-containing contrast agent is injected into the CBD to display the stone under fluoroscopy and then to confirm complete removal of the stone(s). We described a 65-year-old woman with CBD stones who had undergone cardiac pacemaker implantation and was allergic to iodinated contrast media. We performed ERCP + lithotomy + stent implantation under local anesthesia, with injection of carbon dioxide instead of iodinated contrast into the CBD, and successfully visualized the stones under fluoroscopy and then confirmed complete removal of them. The patient was generally in good condition without complications. Thus, we have demonstrated in this case report that carbon dioxide can be used as a safe, economical, and effective alternative to iodinated contrast agent during ERCP.

Introduction: Patients with familial adenomatous polyposis (FAP) are characterised by the appearance of colorectal cancer if the disease is left to follow its natural course, which means they frequently undergo prophylactic colectomy at a young age. In these patients, duodenal cancer becomes the leading cause of death, which deems surveillance necessary. Gastric cancer, although rare, can also occur in these patients, and total gastrectomy is the usual treatment option.

Patients and methods: We used a pedicled isoperistaltic jejunal flap interposition technique to reconstruct the digestive tract after a total gastrectomy so that duodenal surveillance could be maintained in patients followed in outpatient consultation for genetic diseases. We also describe how this technique was performed fully through laparoscopy in two of these cases.

Results: We identified four patients with FAP who developed malignant or extensive pre-malignant gastric lesions which were not endoscopically resectable. Two patients were submitted to open surgery and the remaining two underwent laparoscopic surgery. There was no perioperative or post-operative morbidity, and all four patients are alive at the time of writing, with a minimum follow-up of 12 months. They were not diagnosed with major nutritional imbalances and were routinely submitted to endoscopic duodenal surveillance, sometimes including polypectomy, with ease.

Conclusion: In our experience, this surgical technique has good results, and all surgical steps can be done entirely through laparoscopy, with every advantage this approach entails.

Introduction: Transvaginal natural orifice specimen extraction surgery (NOSES) is an innovative and feasible approach for left-sided colorectal resections in females. This study aimed to report our experience with transvaginal NOSES for left-sided laparoscopic colorectal resections.

Patients and methods: We analysed data for all patients with transvaginal extraction performed for left-sided laparoscopic colorectal resections between 2011 and 2021 at a tertiary teaching hospital in Taiwan.

Results: The 18 post-menopausal patients were of a mean age of 69.2 ± 10.14 years. The lesions were located at the descending ( n = 5), sigmoid colon ( n = 12) and rectum ( n = 1). The operative time was 262.5 ± 83.91 min, and the blood loss was 34 ± 35.98 mL. All patients had an end-to-end anastomosis, and the anastomotic height was 15.06 ± 8.57 cm. Two patients received diversion stoma. The mean length of hospital stay was 5.1 days (standard deviation ± 2.42; range: 3-12 days). There were no cases of clinical infection. The pathology was malignancy ( n = 14, 77.8%), diverticulitis ( n = 2, 11.2%) and benign ( n = 2, 11.2%). In cancers, they were Stage I ( n = 1, 7.1%), IIa ( n = 1, 7.1%), IIIb ( n = 15, 78.7%) and IV ( n = 1, 7.1%). Malignant specimens ( n = 14) were mostly moderately differentiated ( n = 11, 78.6%), with two poorly differentiated (14.3%) and one well-differentiated (7.1%). The lymph nodes harvested were 16.1 ± 8.11. The widest dimension of the lesion was 3.43 cm ± 1.28 (range: 1.5-6) and the length of the specimen was 14.69 cm ± 5.01 (range: 8-27).

Conclusion: Transvaginal NOSES is safe and feasible for left-sided colorectal resection. Factors to consider are the characteristics of the specimen, anal canal and vagina.

Abstract: Foreign body (FB) ingestion results in perforation in 1% of cases and is associated with significant morbidity and rarely mortality. This case reports the delayed presentation of distal ileal perforation following accidental ingestion of solidified root pulp. A 46-year-old male presented to the emergency department with complaints of right iliac fossa pain, clinical diagnosis of appendicitis was made. Computed tomography of the abdomen revealed an FB in the distal ileum with contained perforation. Revised history was suggestive of FB aspiration during root canal therapy 3 weeks back. The patient underwent diagnostic laparoscopy, removal of FB and primary closure of the perforation. FB was revealed to be solidified root pulp macroscopically and hyalinised material microscopically. Localised perforation following ingestion of FB results in significant morbidity due to delayed diagnosis. With the increasing number of dental procedures, this becomes relevant globally as well. Varied clinical presentations pose diagnostic challenges to the clinician.

Introduction: Pancreaticojejunostomy have been studied and modified for more than a hundred years. We investigated a new method of pancreaticojejunostomy to explore its value in laparoscopic pancreaticoduodenectomy.

Patients and methods: A retrospective analysis was conducted on the clinical data of 93 patients who underwent laparoscopic pancreaticoduodenectomy with 'Shunt-block combined' pancreaticojejunostomy at Ningbo Medical Center Lihuili Hospital from April 2017 to February 2023.

Results: All patients successfully completed the surgery, with two cases requiring conversion to open surgery. The average operation time was 328.5 (180-532) min, the average intraoperative blood loss was 182.9 (50-1000) mL and the average laparoscopic pancreaticojejunostomy time was 29.6 (20-39) min. There were no cases of grade C pancreatic fistula postoperatively, 10 cases of grade B pancreatic fistula, 43 cases of biochemical fistula and 40 cases without detected pancreatic fistula.

Conclusion: 'Shunt-block combined' pancreaticojejunostomy was a safe and effective method for pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy.
