ABSTRACT
Complete mesocolic excision (CME) with D3 lymphadenectomy for colon cancer has been shown to improve overall as well as disease-free survival compared to conventional right hemicolectomy. Performing a laparoscopic CME/D3 right hemicolectomy with intracorporeal anastomosis (ICA) can be technically demanding even for experienced operators. Here, we present a systematic, standardized approach to the surgery.

Objective: To investigate the feasibility, safety and effectiveness of colonic interposition with vascular anastomosis in reconstructing the entire esophagus and hypopharynx after resection of hypopharyngeal cancer with esophageal cancer. Methods: We conducted a retrospective analysis of 4 male patients with simultaneous multiple primary cancers of the hypopharynx and esophagus, aged 47 to 58, treated in the Department of Head and Neck Surgery at the Hunan Cancer Hospital from February to August 2019. All cases underwent total hypopharyngectomy and total esophagectomy, of whom, three cases presented with total laryngectomy and one case with larynx preservation. Colonic interposition was performed using the left colic artery as a pedicle, with an average colonic length of 48.5 cm. The colon was elevated through the esophageal bed to the neck, and the branch of the colonic mesenteric artery was anastomosed to one of the neck arteries, including the inferior thyroid artery in one case, the transverse cervical artery in two cases, and the superior thyroid artery in one case, and all venous anastomoses were performed with the internal jugular veins. Results: The postoperative neck and abdominal wounds healed well without anastomotic leakage, and all patients were able to resume a regular oral diet within 21-30 days postoperatively. During the follow-up of 48-52 months, two cases died due to tumor recurrence, while the remaining two cases were disease-free survivals. Conclusion: Colonic interposition with vascular anastomosis is a safe and reliable reconstruction method suitable for repairing long-segment upper digestive tract defects after resection of hypopharyngeal cancer with esophageal cancer.

BACKGROUND: Anastomotic leakage (AL) is the most frequent life-threating complication following colorectal surgery. Several attempts have been made to prevent AL. This prospective, randomized, multicentre trial aimed to evaluate the safety and efficacy of nebulised modified cyanoacrylate in preventing AL after rectal surgery. METHODS: Patients submitted to colorectal surgery for carcinoma of the high-medium rectum across five high-volume centres between June 2021 and January 2023 entered the study and were randomized into group A (anastomotic reinforcement with cyanoacrylate) and group B (no reinforcement) and followed up for 30 days. Anastomotic reinforcement was performed via nebulisation of 1 mL of a modified cyanoacrylate glue. Preoperative features and intraoperative and postoperative results were recorded and compared. The study was registered at ClinicalTrials.gov (ID number NCT03941938). RESULTS: Out of 152 patients, 133 (control group, n = 72; cyanoacrylate group, n = 61) completed the follow-up. ALs were detected in nine patients (12.5%) in the control group (four grade B and five grade C) and in four patients (6.6%), in the cyanoacrylate group (three grade B and one grade C); however, despite this trend, the differences were not statistically significant (p = 0.36). However, Clavien-Dindo complications grade > 2 were significantly higher in the control group (12.5% vs. 3.3%, p = 0.04). No adverse effects related to the glue application were reported. CONCLUSION: The role of modified cyanoacrylate application in AL prevention remains unclear. However its use to seal colorectal anastomoses is safe and could help to reduce severe postoperative complications.

BACKGROUND: Retrosternal oesophageal reconstructions with collar anastomoses can become necessary when the stomach is either unavailable for oesophageal replacement, or orthotopic reconstruction is deemed impractical. Our aim was to analyse our results regarding technical approaches and outcomes. MATERIALS AND METHODS: All patients undergoing primary and secondary oesophageal retrosternal reconstructions with collar anastomoses at our centre (2019-2023) were retrospectively analysed and individual surgical reconstruction options were presented. RESULTS: Overall, twelve patients received primary (n = 5; 42.7%) or secondary (n = 7; 58.3%) reconstructions; ten with colonic interposition and two with gastric pull-up. Male/female ratio was 4:8; median age 66 years (30-87). Charlson-Comorbidity-Score (CCS) was 5 (1-7); 8/12 patients (67%) had ASA-classification score ≥ 3. We observed no conduit necrosis, but one patient (8.3%) with a leakage of the oesophago-colonostomy which was successfully treated by endoscopic vacuum therapy. Four patients (33.3%) acquired nosocomial pneumonia. Additional drainages for pleural fluid collections were necessary in three patients (25%). Overall comprehensive-complication-index (CCI) was 26.2 (0-44.9). Length-of-stay (LOS) was 22 days median (15-40). There was no 90-days mortality. Overall, CCI during the follow-up (FU) period at median 26 months (16-50) was 33.7 (0-100). 10 out of 12 patients were on sufficient oral nutrition at 12 months FU. CONCLUSION: Primary and secondary oesophageal retrosternal reconstructions encompass diverse entities and typically requires tailored decision-making. These procedures, though rare, are feasible with acceptable complication rates and positive functional outcomes when performed in experienced hands.

INTRODUCTION: Ulcerative Colitis (UC) is an Inflammatory Bowel Disease (IBD). Surgery is required in cases of severe acute colitis, massive hemorrhage, toxic megacolon, and perforation; in such cases colectomy and JpouchIleoanal anastomosis (IPAA) are performed. The aim of this study was to evaluate functional outcome, and patient satisfaction and Quality of Life (QoL) after surgery. MATERIAL AND METHODS: Questionnaires were administered to 24 patients with UC undergoing surgery from 2011 to 2022. RESULTS: Mean age at IPAA was 10.8 years. Twenty patients underwent IPAA in 3 operations, 4 patients in 2. All patients underwent laparoscopic surgery. 6 months after surgery mean level of satisfaction was 8.7/10, perception of health status was 7.4. Twenty-three patients (95.8%) recommended IPAA. For 20 patients (83.3%) surgery did not cause delay in education, while 14 patients (58.3%) played sport. The lowest number of evacuations was 9.2 per day, the highest 13.3. Seventeen patients (70.8%) had no incontinence and 15 patients (62.5%) were not affected by pouchitis. After 12 months mean satisfaction level raised up to 9.2/10, perception of health status to 8.5. School absences decreased and no other patients showed any delay in education. Seventeen (70.8%) patients played sports. The number of evacuations decreased: the lowest number was 5.1 per day, the highest 7.5. Twenty patients (83.3%) were continent and 12 (50%) did not use antibiotics. CONCLUSION: Most patients show a good functional outcome in defecation frequency and continence, which has improved through time, number of pouchitis episodes has increased. Patients appear satisfied after surgery.

BACKGROUND: Needlescopic surgery is a minimally invasive procedure that uses thin trocars with 3-mm diameter. We used Turnbull-Cutait pull-through and delayed coloanal anastomosis in needlescopic surgery to avoid diverting ileostomy during intersphincteric resection for low rectal cancer. In this study, we aim to assess the diverting ileostomy avoidance rate and technical safety of this "minimal skin incision and no stoma" procedure. METHODS: This single-center retrospective study was conducted at the Cancer Institute Hospital, a tertiary referral center in Japan. Between January 2017 and December 2020, 11 patients underwent needlescopic intersphincteric resection with diverting ileostomy (NSI group), and 19 patients underwent needlescopic intersphincteric resection with delayed coloanal anastomosis (NSD group) for low rectal cancer. Data regarding patient backgrounds and short-term outcomes, including diverting ileostomy avoidance rate, pathological results, and postoperative defecatory function, were compared between the groups. RESULTS: There were no statistically significant differences between the NSI and NSD groups with respect to patient background, operation time (239 min versus 220 min, p = 0.68), estimated blood loss (45 g versus 25 g, p = 0.29), R0 resection rate (100% versus 100%, p = 1.00), and length of postoperative hospital stay (16 days versus 17 days, p = 0.42). The diverting ileostomy avoidance rate was 94.4% in the NSD group. The LARS and Wexner scores 12 months after surgery were not significantly different between the two groups. CONCLUSIONS: Needlescopic intersphincteric resection and delayed coloanal anastomosis can be safely performed in selected patients with a high rate of diverting ileostomy avoidance and comparable short-term outcomes.

Vaginal natural orifice transluminal endoscopic surgery (vNOTES) for colorectal cancer utilizes transvaginal access for bowel mobilization, vascular pedicle ligation, oncological resection, and bowel anastomosis, along with subsequent transvaginal natural orifice specimen extraction (NOSE), reducing or eliminating the need for transabdominal access. In this report, we describe the technique of vNOTES right hemicolectomy for cecal cancer, with intracorporeal anastomosis and transvaginal NOSE, including a step-by-step operative video. The patient was a 59-year-old Chinese female (body mass index 32.0 kg/m2) with a cT3N0M0 3 cm cecal adenocarcinoma. Posterior colpotomy was created with insertion of a dual-ring wound protector. vNOTES D2 right hemicolectomy with a fully stapled intracorporeal anastomosis was performed via a homemade transvaginal glove port, using extra-long rigid instruments. A 10 mm, 30° rigid laparoscope was used for operative visualization through a transumbilical port, without additional percutaneous trocars. Operative difficulties pertained to suboptimal instrument reach, lack of triangulation, and frequent clashing within the restricted access space. Surgical duration was 300 min, with 50 ml of blood loss. There was minimal postoperative pain. Return of bowel function occurred on postoperative day 2, with discharge from hospital on postoperative day 3. The patient resumed normal daily activities and regular diet by 1-week post-surgery. Self-reported cosmetic satisfaction score was excellent. No operative complications were observed at 2 months' follow-up. vNOTES right hemicolectomy with intracorporeal anastomosis is safe and feasible in highly selected colon cancer patients. Operators should be proficient in conventional laparoscopic colectomy and transvaginal NOSE. More experience with the vNOTES technique is required to ascertain best practices.

We demonstrated successful treatment of patients with complicated central lung cancer, who underwent right upper sleeve lobectomy with carinal resection. We have used the following options for carinal reconstruction: anastomosis of trachea with the left main bronchus and anastomosis of intermediate bronchus with the left main bronchus (clinical case No. 1) or with trachea (clinical case No. 2). Cervicothoracotomy provided correct N-staging and mobilization of trachea with left main bronchus. This approach provided compliance with oncological principles of surgical treatment of lung cancer and significantly reduced tension of anastomosis. These aspects are important for satisfactory immediate functional and oncological results after right upper sleeve lobectomy with carinal resection.

Although circular staplers offer technical advancements over traditional hand-sewn techniques, their use remains challenging for unskilled users, necessitating substantial time and experience for mastery. In particular, it is challenging to apply a consistent pressure of an appropriate magnitude. We developed an automated circular anastomosis device using artificial intelligence (AI) to solve this problem. Automation through AI reduces experiential factors during the anastomosis process. We defined damage occurring during the anastomosis process, noting that a greater depth of damage indicated a more severe injury. For automated anastomosis, data at a tissue strain of 40% were used for the AI model, as this strain level showed optimal performance based on the accuracy and cost matrix. We compared the outcomes of automated anastomosis using a trained AI with those of unskilled users. The results were validated using the Shapiro-Wilk test and t tests. Compression damage was verified on collagen sheets. The AI-driven automatic compression system resulted in less damage compared to unskilled users. In particular, a more significant difference in damage was observed in poor-condition collagen than in good-condition collagen. Damage to the collagen under poor conditions was 54.8% when handled by unskilled users, while the AI-driven automatic compression system resulted in 38.9% damage. This study confirmed that novices' use of AI for automated anastomosis reduces the risk of damage, especially for tissues in poor condition.

PURPOSE: This study analyzed the efficacy of web excision combined with a pre-membranous incision on the dilated proximal segment for congenital intestinal atresia with type I and stenosis (CIA-I/S). PATIENTS AND METHODS: Twenty-six patients underwent surgery for CIA-I/S from January 1990 to June 2022. Patients were categorized into 3 groups according to the surgical procedure: Group A, web excision with pre-membranous incision of the dilated intestine (n = 14); Group B, enteroplasty with a trans-membranous vertical incision (n = 7) and Group C, diamond-shaped anastomosis (n = 5). To minimize the impact of obstruction location on outcomes, we specifically examined 17 cases of duodenal atresia/stenosis: Group D-A, (n = 6); Group D-B, (n = 6) and Group D-C, (n = 5). We retrospectively compared the operative and postoperative parameters among the three groups. RESULTS: No patient experienced anastomotic leakage or obstruction. There were no significant differences in operative duration or blood loss among the 3 Groups. The median time to feeding initiation was 4, 6.5, and 5 days in Groups A, B, and C, respectively (p = 0.04) and was 4, 6.5, and 5 days in Groups D-A, D-B, and D-C, respectively (p = 0.04). CONCLUSION: Web excision, when compared to enteroplasty and diamond-shaped anastomosis, showed comparable results in terms of the operative duration and postoperative complications. However, it may allow for an earlier initiation of enteral nutrition.

PURPOSE: Kono-S anastomosis, an antimesenteric, functional, end-to-end handsewn anastomosis, was introduced in 2011. The aim of this meta-analysis is to evaluate the safety and effectivity of the Kono-S technique. METHODS: A comprehensive search of MEDLINE (PubMed), Embase (Elsevier), Scopus (Elsevier), and Cochrane Central (Ovid) from inception to August 24th, 2023, was conducted. Studies reporting outcomes of adults with Crohn's disease undergoing ileocolic resection with subsequent Kono-S anastomosis were included. PRISMA and Cochrane guidelines were used to screen, extract and synthesize data. Primary outcomes assessed were endoscopic, surgical and clinical recurrence rates, as well as complication rates. Data were pooled using random-effects models, and heterogeneity was assessed with I² statistics. ROBINS-I and ROB2 tools were used for quality assessment. RESULTS: 12 studies involving 820 patients met the eligibility criteria. A pooled mean follow-up time of 22.8 months (95% CI: 15.8, 29.9; I2 = 99.8%) was completed in 98.3% of patients. Pooled endoscopic recurrence was reported in 24.1% of patients (95% CI: 9.4, 49.3; I2 = 93.43%), pooled surgical recurrence in 3.9% of patients (95% CI: 2.2, 6.9; I2 = 25.97%), and pooled clinical recurrence in 26.8% of patients (95% CI: 14, 45.1; I2 = 84.87%). The pooled complication rate was 33.7%. The most common complications were infection (11.5%) and ileus (10.9%). Pooled anastomosis leakage rate was 2.9%. CONCLUSIONS: Despite limited and heterogenous data, patients undergoing Kono-S anastomosis had low rates of surgical recurrence and anastomotic leakage with moderate rates of endoscopic recurrence, clinical recurrence and complications rate.

BACKGROUND: Meta-analysis of 10 randomized prospective trials demonstrated a higher risk of postoperative bleeding from pancreaticogastrostomy (PG) compared with pancreatojejunostomy following pancreatoduodenectomy (PD). This study evaluated the incidence, risk factors, and treatment of anastomotic bleeding from invaginated PG. METHODS: We retrospectively evaluated all consecutive PDs performed between April 1, 2011 and December 31, 2022 using invaginated PG by the double purse-string technique. Multivariate analysis identified risk factors for anastomotic PG bleeding. RESULTS: During the study, 695 consecutive patients with a median age of 66 years underwent PD; the majority was performed for ductal pancreatic adenocarcinomas. Simultaneous vascular resections were performed in 328 patients. Postoperative mortality was 4.1%. Bleeding from PG occurred in 33(4.6%) patients at a median interval of 5 days (range, 1-14) from surgery, leading to reoperation in 21(63%). PG bleeding-related mortality was 9.0%. Multivariate analyses identified a soft pancreatic texture and Wirsung duct > 3 or ≤ 3 mm (Class C and D, respectively, of the ISGPS) (odds ratio [OR]: 2.17, 95% confidence interval [95% CI]: 1.38-3.44; P = 0.0009) and wrapping of the invaginated pancreas (OR: 0.37, 95% CI: 0.17-0.84; P = 0.01) as independent risk factors for PG bleeding. CONCLUSIONS: In a large volume setting, anastomotic bleeding from invaginated PG occurred in ~ 5% of patients and was associated with soft pancreatic parenchyma and small wirsung duct. The reduced rate of PG bleeding observed with wrapping of the invaginated pancreatic stump warrants further evaluation in a prospective randomized study.

To investigate the short-term clinical efficacy of laparoscopic proximal gastrectomy with modified Kamikawa anastomosis and laparoscopic total gastrectomy with Roux-en-Y anastomosis. Retrospective cohort study was conducted. The clinicopathological data of 268 patients who underwent laparoscopic proximal gastrectomy for adenocarcinoma of esophagogastric junction and upper gastric adenocarcinoma from January 2016 to October 2022 were collected. Among 268 patients, 26 underwent laparoscopic proximal gastrectomy with modified Kamikawa anastomosis were assigned to Kamikawa group and 242 underwent laparoscopic total gastrectomy with Roux-en-Y anastomosis were assigned to Roux-en-Y group. The sex, age, BMI, preoperative albumin, maximum tumor diameter, histological grade, and pathological stage of patients in the Kamikawa group and the Roux-en-Y group were subjected to 1:1 propensity score matching. After matching, 16 patients in Kamikawa group and Roux-en-Y group were respectively included in this study. Outcome measures: (1) Intraoperative condition. (2) Postoperative recovery. (3) Follow-up information. The patients' nutritional status, reflux esophagitis and anastomotic stoma were investigated by outpatient and telephone follow-up. Nutritional status assessment comprising body mass index and Nutritional Risk Screening 2002 score. (1) Intraoperative condition. All patients successfully underwent laparoscopic proximal gastrectomy and total gastrectomy. Compared with Roux-en-Y group, the digestive tract reconstruction time in Kamikawa group was longer 93.0(74.0-111.0)min vs. 39.7(35.1-46.2)min, t = -2.001, P = 0.055., and the difference was statistically significant (P < 0.05). There was no statistically significant difference in total operation time and intraoperative blood loss (P > 0.05). (2) Postoperative recovery. There was no statistically significant difference between Kamikawa group and Roux-en-Y group in first anal exhaust time, first postoperative liquid intake time, postoperative hospitalization time, and postoperative complications (P > 0.05). (3) Follow-up information. All patients were followed up. BMI and NRS 2002 scores in Kamikawa group were better than those in Roux-en-Y group at 6 and 12 months after surgery 22.9 ± 3.0 kg/m2 vs. 20.8 ± 2.2 kg/m2, t = 2.165, P = 0.038; 23.1 ± 3.0 kg/m2 vs. 20.3 ± 2.2 kg/m2, t = 3.022, P = 0.005 and 2 (1-2) vs. 2 (1-3), Z = -2.585, P = 0.010; 2 (1-2) vs. 2 (1-3), Z = -2.273, P = 0.023., the difference was statistically significant (P < 0.05). There was no significant difference in GERD scale score and occurrence of ≥ Grade B reflux esophagitis at 6 and 12 months after surgery between Kamikawa group and Roux-en-Y group (P > 0.05). Anastomotic stenosis was not found in all patients by postoperative upper gastrointestinal angiography. Laparoscopic proximal gastrectomy with modified Kamikawa anastomosis is safe and feasible for the treatment of esophagogastric junction and upper gastric adenocarcinoma, and can achieve good anti-reflux effect. Besides, compared with traditional laparoscopic total gastrectomy, its postoperative nutritional status is better.

BACKGROUND: In patients who require complex abdominal wall reconstruction (CAWR), the need for a bowel anastomosis could impact procedure choice and outcome. In this retrospective cohort study, we examine the effect of bowel anastomosis on complications and hernia recurrence. METHODS: All patients who underwent CAWR between 2011 and 2021 by the senior author were reviewed in a retrospective cohort analysis. Patients were included if they met the above criteria. Patients were excluded if they did not undergo the above procedure or if they underwent a different procedure simultaneously. Univariate analysis was performed for patients who underwent bowel anastomosis, and multiple variable logistic regression analysis was performed with respect to overall complications. RESULTS: A total of 264 patients underwent CAWR over a 10-year interval. A total of 41 patients underwent bowel anastomosis (16%), and 223 patients (84%) underwent CAWR without bowel anastomosis. Mean patient age was 55.50 ± 11.55 years. Mean patient body mass index was 32.36 ± 7.31 kg/m 2 . Mean follow-up time was 10.20 months. There was a significant difference in hernia repair etiology, with higher rates of recurrent hernia repair among patients receiving bowel anastomosis (odds ratio, 2.98; 95% confidence interval, 1.49-5.95; P = 0.0018). Acellular dermal matrix was used more frequently in patients who required a bowel anastomosis (odds ratio, 3.74; 95% confidence interval, 1.75-8.00; P = 0.0018). Major and minor complications were also significantly higher in this cohort. Regression analysis for overall complications revealed the presence of bowel anastomosis, fascial repair technique, and follow-up time as independent predictors of overall complications. CONCLUSION: Bowel anastomosis performed at the time of CAWR significantly increased the rate of overall and major complications but did not predict hernia recurrence. Plastic surgeons should utilize this information in counseling patients and in deciding the most appropriate hernia repair technique.

BACKGROUND: In breast reconstruction, arterial coupling has been reported to be more favorable in the thoracodorsal artery (TDA) than the internal mammary artery (IMA). This technique may help overcome anastomosis in a small, deep space. Understanding the arteries' mechanical properties is crucial for breast reconstruction's safety and success. METHODS: Abdominal-based free flap breast reconstructions performed by a single surgeon between 2020 and 2022 were retrospectively analyzed. The patients were classified by microanastomosis technique (handsewn and coupler device) to compare the rate of vascular revision. Histomorphometric analysis of arterial coupling in TDA and IMA was performed in 10 fresh cadavers for comparing wall thickness and composition, including densities of elastic fiber, smooth muscle, and collagen. RESULTS: A total of 309 patients (339 reconstructed breasts) were included. There were 29 patients in the TDA handsewn group (A), 38 patients in the TDA coupler group (B), and 242 patients in the IMA handsewn group (C). The rates of arterial revision in groups A, B, and C were 0.00% (95%CI: 0.00%-11.03%), 2.5% (95%CI: 0.44%-12.88%), and 1.49% (95%CI: 0.58%-3.77%), respectively, with no statistically significant differences (p-value = .694). Histologically, the thickness of the tunica media and adventitia between IMA and TDA showed no significant difference. The density of elastic fiber was significantly higher in IMA (16.70%) than in TDA (0.79%) (p-value <.001). CONCLUSION: The histologic characteristics of TDA are more favorable for arterial coupling than those of IMA. Arterial coupling is a safe option in situations where TDA anastomosis must be performed through a narrow and deep incision.
