Innovative needle-assisted technique for intracorporeal anastomosis: Simplifying closure of common enterotomy in laparoscopic gastrointestinal surgery.

Intracorporeal anastomosis offers notable advantages over extracorporeal techniques, including reduced tissue manipulation leading to faster recovery and potentially lower risks of surgical site infections and complications. However, it also involves several challenges, such as increased operative time and the need for experienced assistants and multiple trocars. Our novel technique addresses these problems. We present a novel approach for closing common enterotomies during intracorporeal anastomosis by using a linear stapler. This technique involves the use of a 6-cm straight needle, which facilitates closure of the common enterotomy. The technique can be performed independently by a single surgeon without the need for additional trocars or assistants. This technique was applied for 20 patients undergoing laparoscopic gastrointestinal surgery between June 2023 and February 2024. The median age of the enrolled patients was 65years, with laparoscopic right hemicolectomy with intracorporeal ileocolostomy being the most common procedure (60% of cases). The median anastomosis time was 22.5min. No occurrence of anastomotic leakage was reported, and only one patient (5%) developed temporary postoperative bowel obstruction, which was managed conservatively. Our technique enables efficient and safe closure of common enterotomies during intracorporeal anastomosis, minimizing reliance on additional trocars and experienced assistants. It simplifies the procedure and ensures fullthickness stapling, potentially reducing the likelihood of complications. Because of its broad applicability across various laparoscopic surgeries, this technique offers substantial benefits and is worth recommending for intracorporeal anastomosis.

Preventive Effects of Bioabsorbable Anti-Adhesion Barriers on Bowel Obstruction After Colectomy in Colon Cancer Patients: A Retrospective Cohort Study Using an Insurance Claims Database.

Postoperative adhesions can be prevented by the use of bioabsorbable anti-adhesion barriers. Although the occurrence of postoperative bowel obstruction is an important concern for patients, at the time of approval of anti-adhesion barriers, its effectiveness in preventing postoperative bowel obstruction had not been evaluated. We aimed to retrospectively evaluate the incidence of bowel obstruction after colectomy in patients with colon cancer using an insurance claims database. This retrospective cohort study analyzed the data of colon cancer patients (between 2005 and 2017 from a national insurance claims database) who underwent colectomies to compare the proportion of individuals with postoperative bowel obstruction between the barrier and no barrier groups. Of the 587 patients who met the inclusion criteria, 308 and 279 patients were identified as the barrier and no barrier groups, respectively. The incidence of postoperative bowel obstruction was significantly lower in the barrier group (log-rank test, P = 0.0483). The cumulative incidence of postoperative bowel obstruction 37 months after the initial colectomy was 6.1% and 10.9% in the barrier and no barrier groups, respectively. Moreover, consistent results were obtained in the matched cohort. In colectomies for patients with colon cancer, the use of anti-adhesion barriers could significantly reduce the incidence of postoperative bowel obstruction. Evaluations using insurance claims databases could provide important information on outcomes following implementation of medical devices.

Establishment of a postoperative bowel adhesion model in Rats

Postoperative adhesive bowel obstruction is a frequent cause of hospital admission in a surgical department. Emergency surgery is needed in a majority of patients with bowel ischemia or peritonitis; most adhesive bowel obstruction can be managed non-operatively. Many studies have investigated benefits of using oral water-soluble contrast to manage adhesive bowel obstruction. Treatment recommendations are still controversial. Intestinal adhesions commonly occur in patients after abdominal surgery, often between intestines, between intestines and the abdominal wall, or within the peritoneum. Adhesions can lead to symptoms such as abdominal pain, constipation, and bloating, and may result in serious complications such as intestinal obstruction, bowel necrosis, acute peritonitis, and sepsis, which can be life-threatening. Therefore, reducing the occurrence of intestinal adhesions is crucial for abdominal surgery. To minimize adhesions, endoscopic techniques can be employed to reduce the abdominal opening area and thus decrease the probability of adhesion formation. However, this approach requires specialized equipment and surgical skills, making it somewhat challenging. Alternatively, anti-adhesion products can be used to lower the risk of adhesion formation. In this study, a murine cecal abrasion adhesion model was established and will be simulated common adhesion scenarios observed in patients after abdominal surgery. The efficacy of anti-adhesion gel materials will be then evaluated to assess their anti-adhesion properties. The record of gross adhesion severity assessment was performed. The adhesion status between the cecum and abdominal wall was observed on postoperative days 3 and 14. The results was shown that three days post-surgery operation, the group exhibited more severe adhesions upon gross examination. By day 14 post-surgery operation (at animal sacrifice), the histopathological analysis revealed that the group exhibited thicker fibrous tissue thickness, increased neovascularization, and higher collagen accumulation in the peritoneum. Therefore, based on the results of this experiment, a postoperative bowel adhesion rat is reliable and can be safely used to test the efficacy of novel anti-adhesive formulations to prevent intra-abdominal adhesions by using this model.

Safety and Efficacy of Barbed Sutures Compared to Non-barbed Sutures in Bariatric Surgery: An Updated Systematic Review and Meta-analysis.

Mastering intracorporeal suturing is challenging in the evolution from conventional to laparoscopic bariatric surgery. Among various techniques competing for superiority in overcoming this hurdle, we focus on exploring the potential of barbed sutures through a meta-analysis that compares outcomes to those of conventional non-barbed sutures in bariatric surgery. We conducted a comprehensive search on PubMed, Scopus, and Embase to identify studies comparing barbed sutures with non-barbed sutures in bariatric surgeries, focusing on outcomes such as operative time, suturing time, postoperative complications, and hospital stay. The statistical analysis was carried out using RStudio version 4.3.2. Heterogeneity was assessed using the Cochrane Q test and I2 statistics. Incorporating data from 11 studies involving a total of 27,442 patients, including 3,516 in the barbed suture group across various bariatric surgeries, our analysis demonstrates a significant reduction in suturing time (mean difference -4.87; 95% CI -8.43 to -1.30; p < 0.01; I2 = 99%) associated with the use of barbed sutures. Specifically, in Roux-en-Y gastric bypass, we observed a significant decrease in operative time (mean difference -12.11; 95% CI -19.27 to -4.95; p < 0.01; I2 = 93%). Subgroup analyses and leave-one-out analyses consistently supported these findings. Furthermore, we found that the mean body mass index did not significantly predict the mean difference in operative time outcome. No significant differences emerged in hospital stay or postoperative complications, including leak, bleeding, stenosis, and bowel obstruction (p > 0.05). Our study findings address barbed sutures as a potential alternative for laparoscopic intracorporeal suturing in bariatric surgery.

CC vs. CC-Plus: A Comparison between Two Cranial-to-Caudal Approaches for Laparoscopic Right Hemicolectomy: A Single-Center Retrospective Study.

Colorectal cancer is a leading cause of cancer-related deaths worldwide, with approximately 1.9 million new cases and over 935,000 deaths in 2020. Right-sided colon cancer, a subset of colorectal cancer, represents a significant health burden. Laparoscopic colon surgery has significantly improved postoperative recovery. The superiority of one approach or landmark over another is still argued about due to the lack of large-scale prospective studies. However, deep understanding both of the anatomical variation and characteristics of each approach is of extreme importance to minimizing adverse effects and maximizing patient benefit after laparoscopic right hemicolectomy. Among these, the cranial-to-caudal approach offers advantages such as reduced intraoperative blood loss, shorter operation time, and decreased risk of vascular injury. The purpose of this study is to compare the efficacy and safety of two cranial-to-caudal approaches for laparoscopic right hemicolectomy (LRH). Specifically, the study aims to evaluate the differences between the conventional cranial-to-caudal approach with medial ligation of the middle colic vein (MCV), and the cranial-to-caudal approach with cranial MCV ligation and surgical trunk sheath opening (CC-plus). The goal is to determine which method offers superior outcomes in terms of intraoperative blood loss, operation time, and overall patient recovery. This single-center retrospective study compared two cranial-to-caudal approaches for LRH. The study included 51 patients who underwent LRH between January 2021 and November 2023 at the Second Affiliated Hospital, Zhejiang University School of Medicine. Patients were divided into two groups: Group A (26 patients) used the cranial-to-caudal approach with medial ligation of the middle colic vein (MCV), and Group B (25 patients) used the cranial-to-caudal approach with cranial MCV ligation and surgical trunk sheath opening (CC-plus). General characteristics, intraoperative parameters, and postoperative outcomes were compared. Statistical analysis was performed using SPSS version 20.0, with significance set at p < 0.05. There were no significant differences between the groups regarding age, gender, tumor location, or clinical staging. All patients achieved R0 resection with no perioperative deaths. The CC-plus group had significantly reduced intraoperative blood loss and shorter operation time compared to the CC group (p < 0.05). No significant differences were found in first postoperative exhausting time, first postoperative defecation time, and postoperative hospital stay between the two groups. Furthermore, no significant differences were evaluated in postoperative complications (surgical site infection (SSI), ileus or bowel obstruction, refractory diarrhea, anastomotic leakage, deep vein thrombosis (DVT), hemorrhage) between the two groups on a median follow up of 12.6 months. Pathological examination showed no significant differences in total lymph nodes dissected and tumor stage. The cranial-to-caudal approach with MCV ligation via the cranial approach (CC-plus) is a safe and effective method for LRH, offering advantages in terms of reduced operation time and intraoperative blood loss. This study's findings suggest that the CC-plus approach may be superior to the conventional cranial-to-caudal approach.

Assessment of the risk of bowel obstruction after laparoscopic vs. open surgery for rectal cancer: A systematic review

ABSTRACT Background This systematic review aimed to evaluate the incidence of adhesion-related readmissions and surgery for adhesive bowel obstruction (BO) in patients who underwent laparoscopic or open surgery for rectal cancer. Laparoscopic surgery is generally believed to be associated with a lower rate of postoperative adhesion formation compared to open surgery. Materials and Methods A thorough and systematic search was conducted across multiple comprehensive databases to identify relevant studies for inclusion in this systematic review. The purpose of this search was to ensure a comprehensive and unbiased selection of studies to provide a robust foundation for the subsequent analysis. Result In this review, a total of 10 studies were involved on bowel obstruction risk in laparoscopic and open surgery for rectal cancer. This study consistently showed that laparoscopic surgery carried a lower risk of postoperative bowel obstruction compared to open surgery. Six studies in the review supported this finding. Conclusion Laparoscopic surgery shows a significant reduction in adhesive bowel obstruction compared to open surgery, as indicated by this systematic review. However, more well-designed randomized trials involving diverse patients are needed to confirm these benefits. Further research is necessary to gain a clearer understanding of the advantages of laparoscopic surgery in reducing the risk of bowel obstruction.

Comprehensive meta-analysis of surgical procedure for congenital diaphragmatic hernia: thoracoscopic versus open repair

PurposePrevious studies have shown a higher recurrence rate and longer operative times for thoracoscopic repair (TR) of congenital diaphragmatic hernia (CDH) compared to open repair (OR). An updated meta-analysis was conducted to re-evaluate the surgical outcomes of TR.MethodsA comprehensive literature search comparing TR and OR in neonates was performed in accordance with the PRISMA statement (PROSPERO: CRD42020166588).ResultsFourteen studies were selected for quantitative analysis, including a total of 709 patients (TR: 308 cases, OR: 401 cases). The recurrence rate was higher [Odds ratio: 4.03, 95% CI (2.21, 7.36), p < 0.001] and operative times (minutes) were longer [Mean Difference (MD): 43.96, 95% CI (24.70, 63.22), p < 0.001] for TR compared to OR. A significant reduction in the occurrence of postoperative bowel obstruction was observed in TR (5.0%) compared to OR (14.8%) [Odds ratio: 0.42, 95% CI (0.20, 0.89), p = 0.02].ConclusionsTR remains associated with higher recurrence rates and longer operative times. However, the reduced risk of postoperative bowel obstruction suggests potential long-term benefits. This study emphasizes the importance of meticulous patient selection for TR to mitigate detrimental effects on patients with severe disease.

Benefit of a laparoscopic jejunostomy feeding catheter insertion to prevent bowel obstruction associated with feeding jejunostomy after esophagectomy.

The placement of a jejunostomy catheter during esophagectomy may cause postoperative bowel obstruction. The proximity of the jejunostomy site to the midline might be associated with bowel obstruction, and we have introduced laparoscopic jejunostomy (Lap-J) to reduce jejunostomy's left lateral gap. We evaluated 92 patients who underwent esophagectomy for esophageal cancer between February 2013 and August 2022 to clarify the benefits of Lap-J compared to other methods. The patients were classified into two groups according to the method of feeding catheter insertion: jejunostomy via small laparotomy (J group, n = 75), and laparoscopic jejunostomy (Lap-J group, n = 17). Surgery for bowel obstruction associated with the feeding jejunostomy catheter (BOFJ) was performed on 11 in the J group. Comparing the J and Lap-J groups, the distance between the jejunostomy and midline was significantly longer in the Lap-J group (50mm vs. 102mm; P < 0.001). Regarding surgery for BOFJ, the distance between the jejunostomy and midline was significantly shorter in the surgery group than in the non-surgery group (43mm vs. 52mm; P = 0.049). During esophagectomy, Lap-J can prevent BOFJ by placing the jejunostomy site at the left lateral position to the midline and reducing the left lateral gap of the jejunostomy.

Modified 2-stage IPAA has similar postoperative complication rates and functional outcomes compared to 3-stage IPAA

IntroductionReconstructive ileal-pouch anal anastomosis (IPAA) for ulcerative colitis (UC) is often created in 3-stages: colectomy ​+ ​ileostomy, proctectomy ​+ ​pouch creation with diverting loop ileostomy, then subsequent ileostomy closure. Modified 2-stage IPAA is without pouch diversion, thus avoiding a third operation. This study compares perioperative complications, quality of life (QOL) and functional outcomes of 3- versus modified 2-stage IPAA. MethodsCharts were reviewed for adult UC patients undergoing IPAA between 2010 and 2020. QOL and function were assessed with EQ-5D-3L Quality of Life and Pouch Functional Score questionnaires. Results152 patients were identified. 43 modified 2-stage and 109 3-stage IPAA were similar for anastomotic leak (9.3% vs. 1.8%, p ​= ​0.06), SSI (34.9% vs. 29.7%, p ​= ​0.51) and ileus (32.6% vs. 33%, p ​= ​0.96). Modified 2-stage had less bowel obstruction than 3-stage IPAA (7.0% vs. 30.1%, p ​= ​0.006). 92 patients returned questionnaires with similar QOL and pouch function. ConclusionsPerioperative complications, QOL and function are similar for 3-stage IPAA and modified 2-stage IPAA. Modified 2-stage IPAA in select patients is safe and has less postoperative bowel obstruction than 3-stage IPAA.

Anesthetic management of a huge retroperitoneal leiomyoma: a case report

BackgroundRetroperitoneal leiomyomas are rare, with just over 100 cases reported in the literature. Perioperative management of retroperitoneal leiomyomas can be challenging due to the large tumor size and the risk of hemorrhage.Case presentationWe report a case of a 40-year-old Han woman with a 40-cm retroperitoneal leiomyoma. General anesthesia was performed for the surgical resection. Key flow parameters like cardiac output and stroke volume variation, as shown by the Vigileo™-FloTrac™ system, enabled the anesthesiologist to implement goal-directed fluid optimization. Acute normovolemic hemodilution and cell salvage technique were used resulting in a successful en bloc tumor resection with a 6000-mL estimated blood loss. Although the patient experienced postoperative bowel obstruction, no other significant complications were observed.ConclusionAdvanced hemodynamic monitoring and modern patient blood management strategies are particularly helpful for anesthetic management of huge retroperitoneal leiomyomas.

Efficacy of ileus tube combined with meglumine diatrizoate in treating postoperative inflammatory bowel obstruction after surgery.

Early postoperative inflammatory small bowel obstruction (EPISBO) is easy to be complicated after colorectal cancer surgery. Both intestinal obstruction catheter and meglumine can treat EPISBO. To investigate the efficacy of an intestinal obstruction tube combined with meglumine diazo in treating EPISBO of colorectal cancer. Data from 60 patients with colorectal cancer and intestinal obstruction admitted to the Proctology Department of our hospital from April 2018 to May 2022 were collected and analyzed and divided into three cohorts according to different treatment regimens. Cohort A (n = 20) received a transnasal intestinal obstruction catheter with panumglumine, and cohort B (n = 20) received a transnasal intestinal obstruction catheter with liquid paraffin. Cohort C (n = 20) received oral treatment with meglumine. The clinical efficacy, first exhaust/defecation time, length of hospital stay, gastrointestinal decompression time, relief time of abdominal pain, and relief time of abdominal distension were compared among the three cohorts. The levels of C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), monocyte chemotactic protein-1 (MCP-1), serum albumin, and transferrin were compared among the three cohorts before and after treatment. The occurrence of adverse reactions in the three cohorts was compared. Compared with cohort C, the successful treatment rate of cohort A was significantly higher. There were statistically significant variations in the time of first exhaust/defecation, length of hospital stays, gastrointestinal decompression time, relief time of abdominal pain, and relief time of abdominal distention among the three cohorts. Compared with cohort C, cohort A's first exhaust/defecation time, hospitalization time, gastrointestinal decompression time, abdominal pain relief time, and abdominal distension relief time was reduced (P < 0.05). After treatment, serum CRP, TNF-α, IL-6, and MCP-1 expression levels increased, and serum albumin and serum transferrin levels increased in the three cohorts. The serum albumin level in cohort A was higher than in cohort C. Compared with cohort B and cohort C, the serum transferrin level in cohort A increased (P < 0.05). Compared with cohort C, the total incidence of adverse reactions in cohorts A and B was significantly higher (P < 0.05). The incidence of adverse reactions was similar between cohort A and cohort B. Using an ileus tube combined with meglumine diatrizoate can effectively treat postoperative inflammatory ileus obstructions after surgery colorectal cancer and improve prognosis, inflammatory response, and nutritional status.

The Effect of Postoperative Gum Chewing on Gastrointestinal Function Following Laparoscopic Gynecological Surgery. A Meta-analysis of Randomized Controlled Trials

To assess the effect of postoperative gum chewing on gastrointestinal function in women following laparoscopic gynecological surgery for benign indications. We screened 5 major databases (Medline, Scopus, Google Scholar, Cochrane Central Register of Controlled Trials, and Clinicaltrials.gov) from inception till February 2023. No language restrictions were applied. We included randomized controlled trials comparing the postoperative bowel function between patients who chewed and patients who did not chew gum postoperatively after laparoscopic gynecological procedures for benign indications. Data from 5 studies on 670 patients were extracted and analyzed by 3 independent reviewers. Meta-analysis was performed with RevMan 5.4 software (Copenhagen: The Nordic Cochrane Center, The Cochrane Collaboration, 2020), with mean differences (MDs), pooled risk ratios, and random-effects model. Postoperative gum chewing significantly reduced the time to first bowel sounds and the time to first passage of flatus (MD -2.58 hours 95% confidence interval (CI) -4.12 to -1.04 p=.001 and MD -3.97 hours 95% CI -6.26 to -1.68 p <.001, respectively). The time to first defecation, the time to first postoperative patients' mobilization, the length of hospital stay, and the risk of postoperative bowel obstruction showed no statistically significant difference between the 2 groups. When subgroup analysis was performed according to the type of the laparoscopic procedure, it failed to reveal a positive impact of postoperative gum chewing in both the times to first passage of flatus and first defecation following laparoscopic hysterectomies (MD -5.35 hours 95% CI -10.93 to 0.23 p=.06 and MD -15.93 hours 95% CI -40.13 to 8.28 p=.20, respectively). The results of the present meta-analysis support that postoperative gum chewing following laparoscopic gynecological procedures seems to have a positive effect on the early mobilization of the gastrointestinal tract. However, these results should be interpreted with caution due to the small number of the included randomized controlled clinical trials.

Stapled side-to-side anastomosis for ileostomy reversal: a simple and reproducible technique with video.

Protective diverting ileostomy is commonly performed in rectal surgery to avoid septic complications of low colorectal anastomosis. Ileostomy closure usually occurs three months after the surgery and can be realized in two ways: hand sewn or stapled. Existing randomized studies comparing the two techniques showed no difference in terms of complications. Our study describes the standard technique of ileostomy reversal as done in Bordeaux University Hospital in 10 steps individually illustrated and with an explicative video. We also collected data concerning the 50 last patients who underwent an ileostomy reversal in our center from June 2021 to June 2022. Mean duration of the ileostomy closure was 46.8 minutes, and the mean total hospital stay was 4.66 days. Five of 50 (10%) patients had a post-operative bowel obstruction, 2/50 (4%) patients had a post-operative bleeding, 1/50 (2%) patient had a wound infection, and there was no anastomotic leakage observed. Stapled side-to-side anastomosis is a rapid, simple, and reproducible technique for ileostomy reversal. There are no more complications compared to hand-sewn anastomosis. It engenders an additional cost compensated by the gain in operating time which altogether saves money.

The incidence and impact of enterotomy during laparoscopic and robotic ventral hernia repair: a nationwide readmissions analysis.

Our aim was to define the national incidence of enterotomy (ENT) during minimally invasive ventral hernia repair (MIS-VHR) and evaluate impact on short-term outcomes. The 2016-2018 Nationwide Readmissions Database was queried using ICD-10 codes for MIS-VHR and enterotomy. All patients had 3-months follow-up. Patients were stratified by elective status; patients without ENT (No-ENT) were compared against ENT patients. In total, 30,025 patients underwent LVHR and ENT occurred in 388 (1.3%) patients; 19,188 (63.9%) cases were elective including 244 elective-ENT patients. Incidence was similar between elective versus non-elective cohorts (1.27% vs 1.33%; p = 0.674). Compared to laparoscopy, ENT was more common during robotic procedures (1.2% vs 1.7%; p = 0.004). Comparison of elective-No-ENT vs elective-ENT showed that elective-ENT patients had a longer median LOS (2 vs 5days; p < 0.001), higher mean hospital cost ($51,656 vs $76,466; p < 0.001), increased rates of mortality (0.3% vs 2.9%; p < 0.001), and higher 3-month readmission (10.1% vs 13.9%; p = 0.048). Non-elective cohort comparison demonstrated non-elective-ENT patients had a longer median LOS (4 vs 7days; p < 0.001), higher mean hospital cost ($58,379 vs $87,850; p < 0.001), increased rates of mortality (0.7% vs 2.1%;p < 0.001), and higher 3-month readmission (13.6% vs 22.2%; p < 0.001). In multivariable analysis (odds ratio, 95% CI), higher odds of enterotomy were associated with robotic-assisted procedures (1.386, 1.095-1.754; p = 0.007) and older age (1.014, 1.004-1.024; p = 0.006). Lower odds of ENT were associated with BMI > 25kg/m2 (0.784, 0.624-0.984; p = 0.036) and metropolitan teaching vs metropolitan non-teaching (0.784, 0.622-0.987; p = 0.044). ENT patients (n = 388) were more likely to be readmitted with post-operative infection (1.9% vs 4.1%; p = 0.002) or bowel obstruction (1.0% vs 5.2%;p < 0.001) and more likely to undergo reoperation for intestinal adhesions (0.3% vs 1.0%; p = 0.036). Inadvertent ENT occurred in 1.3% of MIS-VHRs, had similar rates between elective and urgent cases, but was more common for robotic procedures. ENT patients had a longer LOS, and increased cost and infection, readmission, re-operation and mortality rates.

Intensification of Local Therapy With High Dose Rate, Intraoperative Radiation Therapy (HDR-IORT) and Extended Resection for Locally Advanced and Recurrent Colorectal Cancer

BackgroundWe report our long-term experience with high dose rate intraoperative radiotherapy (HDR-IORT) in a single, quaternary institution. Patients/MethodsFrom 2004 to 2020, 60 HDR-IORT procedures for locally advanced colorectal cancer (LACC) and 81 for locally recurrent colorectal cancer (LRCC) were done in our institution. Preoperative radiotherapy was done prior to majority of the resections (89%, 125/141). Sixty-nine percent (58/84) of the resections involving pelvic exenterations had >3 en bloc organs resected. HDR-IORT was delivered using a Freiburg applicator. A single 10 Gy fraction was delivered. Margin status was R0 and R1 in 54% (76/141) and 46% (65/141) of the resections, respectively. ResultsWith a median follow-up time of 4 years, 3-, 5-, and 7- year, overall survival (OS) rates were 84%, 58%, and 58% for LACC and 68%, 41%, and 37% for LRCC, respectively. Local progression-free survival (LPFS) rates were 97%, 93%, and 93% for LACC and 80%, 80%, 80% for LRCC, respectively. For the LRCC group, an R1 resection was associated with worse OS, LPFS, and progression-free survival (PFS), preoperative EBRT was associated with improved LPFS and PFS, and ≥2 years disease-free interval was associated with improved PFS. The most common severe adverse events were postoperative abscess (n = 25) and bowel obstruction (n = 11). There were 68 grade 3 to 4 and no grade 5 adverse events. ConclusionsFavorable OS and LPFS can be achieved for LACC and LRCC with intensive local therapy. In patients with risk factors for poorer outcomes, optimization of EBRT and IORT, surgical resection, and systemic therapy are required.

Long-term evaluation of patients with BMI = 50kg/m2 who underwent Bariatric Surgery.

to determine the risks and benefits of bariatric surgery in patients with super obesity (SO) in comparison with obesity grades II and III. retrospective cohort that included a study group of 178 patients with SO and a control group of 181 patients with BMI 35-49.9Kg/m2. The groups were formed in a 1:1 nearest neighbor matching. The main variables were pre- and postoperative BMI and comorbidities, occurrence of severe postoperative complications, bowel obstruction, marginal ulcer, fistulae and 30-day death, besides the necessity of emergency room (ER) admission and abdominal computed tomography (CT) scans in the postoperative period due to acute abdomen. the study group comprised 74.0% of women while the control group had 56.7%. The mean follow-up time was similar between both groups (5.48 x 6.09 years, p=0.216). There was no statistically significant difference on the prevalence of hypertension and T2D between the groups according to the surgical technique. All deaths occurred in the Study group (BMI = 50kg/m2) who underwent RYGB. There was no difference between the groups regarding the occurrence of severe complications. Data on ER admissions and the need for abdominal CT to investigate postoperative abdominal pain did not show statistically significant difference between the groups. despite the high risk related to bariatric surgery in patients with SO, the benefits related to the remission of comorbidities are significant; although being lower than those found in patients with milder grades of obesity.

Association between appendiceal stump closure method and post-operative bowel obstruction after laparoscopic appendectomy

BackgroundLaparoscopic appendectomy is one of the most common urgent pediatric surgical operations. Endoscopic surgical staplers and pre-tied endoloop ligatures are both routinely used for closure of the appendiceal stump in children. Practice patterns vary for a number of reasons, including cost, size, and ease of use. While stapling is standard for some pediatric surgeons, others believe that staples can act as a nidus for small bowel obstruction (SBO). However, studies comparing closure methods have been conflicting in their results and limited in size. Therefore, we aim to determine if there is an association between appendiceal stump closure method and SBO using a national comparative pediatric database. MethodsWe queried the Pediatric Health Information System (PHIS) for patients ages 3–18 years who underwent laparoscopic appendectomy for appendicitis between 1/1/2016 – 12/31/2020. We included hospitals that had greater than 50 patients with billing data and excluded patients with inflammatory bowel disease and simultaneous abdominal operations. We used billing data for the patient's appendectomy to determine if a stapler or a suture ligature was used during the case. Our primary outcome of interest was post-operative SBO or reoperation for lysis of adhesion or intestinal surgery within the first 30 post-operative days. Multivariable regression analyses were used to estimate the association between stump closure method and post-operative SBO or reoperation in addition to cost while adjusting for patient demographics and appendiceal perforation. ResultsIn total, 49,191 patients from 37 hospitals were included, of which, 29,733 (60.44%) were male, 21,403 (43.51%) were non-Hispanic white, and 18,291 (37.18%) had a diagnosis of complicated appendicitis. The median [IQR] age of the cohort was 11 [8–14] years. A surgical stapler was used during laparoscopic appendectomy in 35,788 (72.75%) patients, and early SBO or reoperation occurred in 653 (1.33%) patients. In adjusted analysis controlling for demographics and complicated appendicitis there was no statistically significant difference in the odds of SBO or reoperation between the two groups. (OR 1.17; 99% CI 0.86 – 1.6). Complicated appendicitis was the factor most associated with post-operative SBO or reoperation (OR 4.4; 99% CI 3.01 – 6.44). Median cumulative cost was slightly higher on unadjusted analysis in the stapler group ($10,329.3 vs $9,569.2). However, there was no significant difference on adjusted analysis. ConclusionSBO or reoperation following laparoscopic appendectomy for appendicitis is uncommon. Complicated appendicitis is the most predictive factor of this outcome. Adjusting for available patient, disease, and hospital characteristics, use of a surgical stapler does not appear to be meaningfully associated with the development of acute SBO or reoperation. Surgeon preference remains the mainstay for safe appendiceal stump closure method. Level of evidenceLevel III. Study typeRetrospective Comparative Study.

Sugarbaker Versus Keyhole Repair for Parastomal Hernia: a Systematic Review and Meta-analysis of Comparative Studies

IntroductionParastomal hernia is a debilitating complication of stoma creation. Parastomal hernia repair with mesh reduces recurrence rates in open and laparoscopic settings. Recent comparative studies conflict with previously pooled data on optimal mesh repair technique. The objective of this study is to examine parastomal hernia recurrence rates after Sugarbaker and keyhole repairs by performing an updated systematic review and meta-analysis of comparative studies. MethodsA systematic review of PubMed, MEDLINE, EMBASE, the Cochrane database, SCOPUS, and the PROSPERO registry was performed according to PRISMA 2020 guidelines (PROSPERO ID: CRD42021290483). Studies comparing parastomal hernia recurrences after Sugarbaker and keyhole repairs were included. Studies with overlapping patient cohorts (duplicate data), non-comparative studies, studies that did not report the primary outcome of interest, and studies not in the English language were excluded. Study bias was assessed using the Newcastle–Ottawa scale. Pooled mean differences (MD), odds ratios (OR), and risk ratios (RR) with 95% confidence intervals (CI) were calculated. Heterogeneity was assessed using the I2 statistic. Forest plots and funnel plots were generated. Study quality was analyzed using MINORS. Additional subgroup analysis of modern studies was performed. ResultsTen comparative studies published between 2005 and 2021 from 5 countries were included for analysis comprising 347 Sugarbaker repairs and 246 keyhole repairs. There were no differences in patient age, sex, or BMI between the groups. There was no difference between the groups regarding surgical site infection (OR 0.78; CI 0.31–1.98; P = 0.61) or post-operative bowel obstruction (OR 0.76; CI 0.23–2.56; P = 0.66). Sugarbaker repairs were significantly less often associated with parastomal hernia recurrence when compared to keyhole repairs (OR 0.38; CI 0.18–0.78; P = 0.008). There was no significant heterogeneity among the studies comparing parastomal hernia recurrence (I2 = 32%; P = 0.15). Quality analysis revealed a median MINORS score of 11 (range 6–16). Subgroup analysis of studies performed after the previously published pooled analysis (2015–2021) revealed no significant difference in parastomal hernia recurrence between the two groups (OR 0.58; CI 0.24–1.38; P = 0.22) with a significant subgroup effect (P = 0.05). ConclusionsThough there were lower rates of parastomal hernia recurrence with Sugarbaker repairs on overall analysis, this phenomenon disappeared on subgroup analysis of modern studies. Randomized controlled trials with contemporary cohorts would help further evaluate these repairs and minimize potential bias.

Lidocaine, old drug - new possibilities. Treatment of postoperative pain and reduction of postoperative complications with intravenous administration

Introduction: The number of surgeries requiring sedation continues to increase worldwide. Analgesia is one of the main components of anesthesia used during surgical procedures. Despite improvements in surgical techniques, the invention of new analgesics and a significant expansion of knowledge about the pathophysiology of pain, more than 75% of patients experience postoperative pain. Adequate analgesia reduces postoperative complications and shortens the length of hospitalization. Lidocaine is a local anesthetic also used as an antiarrhythmic drug. Studies report that intravenous administration may find application in perioperative analgesia. Aim of the study: The purpose of our study was to determine in which types of surgery the benefits of IVL (Intravenous lidocaine) are greatest.Methods and Evidence: We reviewed the literature available on PubMed using the words "Intravenous lidocaine"; "Perioperative Lidocaine "; "Postoperative pain".Results: IVL has been shown to have a positive effect on reducing opioid doses, postoperative pain intensity, shortening the duration of postoperative bowel obstruction, faster patient rehabilitation and shortening hospitalization. In non-abdominal surgeries, the greatest benefits have been seen in breast surgery, urology and spinal surgery. Lidocaine has low toxicity; only doses several times higher cause adverse effects.Conclusions: IVL should be used during intraabdominal surgery due to its high efficacy. Further studies on a larger group of patients are needed to better determine the effects of IVL in other surgeries. Keywords: "Intravenous lidocaine"; "Perioperative Lidocaine "; "Postoperative pain".

Clinical profile and management of perforation peritonitis in Bharatpur hospital, Nepal: A prospective study

IntroductionThe most common surgical emergency in general surgery is perforation peritonitis. It is a serious condition with a mortality rate of up to 20%, and it is the third most common cause of surgical abdomen after appendicitis and intestinal obstruction. The aim of this study to discuss clinical profile and management of perforation peritonitis in a hospital in central Nepal. MethodsThis prospective study was done for one year at Bharatpur Hospital, Chitwan Nepal. In our study, only patient above 15 years were included and those who were not fit for anesthesia and surgery were excluded. Most of the patient were diagnosed clinically supported by lab investigations and imaging like X-ray and ultrasonography of abdomen. The variables analyzed were the risk factors of the patient like smoking, alcohol, liver disease and previous abdominal surgeries. ResultsThe majority of the patients were in the age group 50–59 years in male and 40–49 years in female. Among sixty cases, 31 were female and 29 were male with Female: Male ratio of 1.06:1. The most common cause of perforation found was peptic ulcer compromising 88.3% (53 cases) followed by appendicular perforation accounting 8.3% (5 cases). Similarly, Tubercular perforation was found in 3.3%. Smoking was most common risk factor accounting 88.3%, followed by alcohol consumption (48.33%) while, 15% of patients had positive history of NSAIDs consumption. On imaging, 38.33% patient had air fluid level on X-ray and 78.33% had gas under diaphragm. On blood investigation, leukocytosis was found in 53.33% of patients, hyponatremia in 10% of patients and hypokalemia in 18.33% of patients. While on urine examination, albumin was found in 5% of patients. The repair of perforation along with omentopexy was done in 73.3% of patients while only repair was done in 15% of patients. Only 8.3% opted for appendectomy while a very few patients (3.3%) went for resection with anastomosis. The Postoperative complications found were wound infection (43.3%), paralytic ileus (18.33%), sepsis (15%), followed by electrolyte imbalance (11.6%), postoperative bowel obstruction (6.6%) and burst abdomen (1.6%). While, there were only 3 cases of mortality. ConclusionsPerforation peritonitis is a frequently encountered surgical emergency. Various factors like age, sex, duration, site of perforation, extent of peritonitis and delay in surgical intervention are associated with morbidity and mortality. A successful management depends upon early surgical intervention, source control and exclusive intraoperative peritoneal lavage.
