Complications associated with laparoscopic sleeve gastrectomy - a review

An Ongoing Dilemma Amid Obesity Pandemic: Is Obesity Surgery Feasible in Turkish Adolescents? A Multicenter Study

Background: A significant percentage of the adolescent population suffers from obesity and its related comorbidities in the modern era. However, the alteration of intestinal anatomy, lack of scientific evidence regarding its safety and efficacy, and various ethical obstacles make surgical intervention to treat obesity in this age group controversial. To address the short-term efficacy and safety of bariatric surgery in adolescent patients, we present the results of 170 adolescent patients with obesity in this study. Materials and Methods: The clinical data of 170 adolescent patients who underwent various bariatric surgeries from March 2012 to January 2020 were evaluated. The presented data include demographics, preoperative and postoperative 6-month body mass index (BMI), excess weight loss (EWL), total weight loss (TWL), comorbidities, pre- and postoperative medications, length of hospital stay (LoHS), and complications. Results: The mean age of the patients was 17 years. The mean BMI was 43.9. In addition, 21.2% of the patients had an obesity-related comorbidity. Laparoscopic sleeve gastrectomy was the most preferred surgical method (94.1%). The LoHS ranged between 3 and 12 days, with an average of 4 days, and no patients required intensive care unit admission. The mean postoperative 6-month BMI, EWL, and TWL were 30.17 kg/m2, 77.7% [17.5%-139.1%], and 31.32% [7.6%-55.8%], respectively. The change in mean BMI values was found to be statistically significant (P < .05). Perioperative and postoperative complications occurred in 1.8% of the patients. Conclusion: Obesity surgery can be safely performed in adolescents, yielding desirable short-term outcomes and acceptable perioperative complication rates when conducted by adult bariatric and metabolic surgeons.

Spontaneous splenic rupture two days after laparoscopic sleeve gastrectomy

INTRODUCTION

Sleeve gastrectomy is a common bariatric procedure to manage morbid obesity. Splenic injury such as splenic rupture after sleeve gastrectomy is a rare complication which can be treated both with a splenectomy or conservative approach, called spleen-preserving surgery.

PATIENTS AND METHODS

A 42-year old male, in whom we performed a sleeve gastrectomy, presented with splenic rupture, within 48 h postoperative, for which spleen-preserving surgery was performed. As splenic rupture is a very rare complication, we performed an extensive literature search in the PubMed database. After obtaining patient informed consent, we aim to describe a sixth presentation of this rare surgical complication.

RESULT

To the best of our knowledge, only five cases of splenic rupture after laparoscopic sleeve gastrectomy have been described before, all treated with a splenectomy. Furthermore, we are the first to describe spleen-preserving surgery.

CONCLUSION

We present the sixth case of spontaneous splenic rupture after laparoscopic sleeve gastrectomy, and the first to treat it with spleen-preserving surgery.

[Treatment and prevention of suture failure and bleeding after various bariatric interventions]

OBJECTIVE

To assess the incidence, treatment and prevention of leakage, as well as bleeding after various types of bariatric interventions.

MATERIAL AND METHODS

There were 3.107 various bariatric interventions between 2020 and 2024 including 1.403 (45.2%) laparoscopic sleeve gastrectomies (LSG), 1.622 (52.2%) laparoscopic mini/one anastomosis gastric bypass procedures (MGB-OAGB) and 82 (2.6%) laparoscopic Roux-en-Y gastric bypass surgeries (RYGB). The incidence of intraperitoneal and intraluminal bleeding, suture failure and incidence of complications depending on intraoperative prevention were evaluated. Efficacy of endoscopic VAC system (vacuum-assisted closure) for suture failure after LSG, MGB-OAGB and RYGB was evaluated.

RESULTS

The overall complication rate between 2020 and 2024 was 1.64% (51 patients), suture failure - 0.45% (14 patients), bleeding - 0.71% (22) cases. Ten (71.4%) patients with suture failure were treated using VAC system. In 9 patients, the defect recovered without external gastric fistula. In 5 patients, defect closure was primary, in 4 patients - secondary, i.e. through ulcerative defect. In 1 patient after LSG, the defect did not heal despite VAC therapy for 21 days, and external gastric fistula occurred. Double treatment of stapler line for prevention of postoperative bleeding and leakage reduced the incidence of leaks by 2.5 times, intra-abdominal bleeding by 23 times, intraluminal bleeding from 0.95% to 0%.

CONCLUSION

Endoscopic VAC system is effective for suture failure after bariatric interventions. Double treatment of stapler suture line can significantly reduce the incidence of bleeding and leakage after LSG, MGB-OAGB and RYGB.

The relationship of decision regret with quality of life and comfort level in patients undergoing laparoscopic sleeve gastrectomy: a cross-sectional study

BACKGROUND

Laparoscopic sleeve gastrectomy (SG) is one of the effective methods of weight loss. It is essential to determine patients' regret and predictive factors to improve their quality of life and comfort. No study has investigated decision regret and affecting factors in patients undergoing SG in Turkey.

OBJECTIVES

The study aimed to determine the relationship of decision regret with quality of life and comfort level in patients undergoing SG.

SETTING

The research was carried out with patients who had undergone SG in a private hospital in the west of Turkey.

METHODS

The research was conducted as a descriptive, correlational, and cross-sectional study. Data were collected between March and May 2023, and the study was completed with 286 patients. Data were collected using the Personal Information Form, Decision Regret Scale (DRS), Quality of Life Following Obesity Surgery Scale (QoL-OS), and Comfort Scale.

RESULTS

Patients' mean score on the DRS was 5.27 ± 13.41 (0-100), the total mean score on the QoL-OS-Biopsychosocial dimension was 79.57 ± 9.35 (18-90), the mean score on the QoL-OS-Complications dimension was 17.17 ± 4.60 (7-35), and the environmental comfort score average was 8.87 ± 2.23 (0-10). Patients' decision regret was significantly affected by the QoL-OS-Biopsychosocial Area dimension in the first place (Beta = -.516; P < .001), social comfort in the second place (Beta = -.278; P < .001), postoperative weight gain in the third place (Beta = .221; P < .001), and complication development in the fourth place (Beta = .163; P < .001).

CONCLUSIONS

The study revealed that patients' decision regret levels were very low up to 3 years after surgery and found that low postoperative quality of life and social comfort level, postoperative weight gain, and complications affected decision regret.

3dct Conduit and Oesophageal Metrics, a Valuable Method to Diagnose Post Sleeve Gastrectomy Abnormalities

PURPOSE

Reflux after laparoscopic sleeve gastrectomy (LSG) may result from anatomical and functional anomalies in the gastric conduit. Three-dimensional CT scans (3DCT) offer a comprehensive view of gastric anatomy. This study aims to establish specific measurements associated with sleeve abnormalities to standardise the reporting of 3DCT which may help in management of LSG complications.

MATERIALS AND METHODS

This retrospective study analysed 64 post-LSG patients who underwent gastric 3DCT. Data included clinical demographics, pre-LSG BMI, BMI at 3DCT, and the duration between surgery and examination. Symptomatology prompts the scan and other concurrent investigations. Various 3DCT measurements were taken, including angularis angle (AA), surface area (ASA), conduit length (CL), proximal maximal surface area (PMSA), and distal maximal surface area (DMSA) of the gastric conduit. Patients were categorised based on endoscopy findings and symptomatology. Outcomes post-revisional surgery were assessed and analysed.

RESULTS

20.3% were male. Pre-LSG BMI and BMI at 3DCT were 45.57 (± 8.3) and 36.3 (± 8.7), respectively. Mean surgery-to-scan period was 6.2 years. 71.8% of patients presented with reflux, regurgitation, or dysphagia, whilst the remainder primarily exhibited weight regain. Patients with endoscopic evidence of stenosis/reflux demonstrated significantly lower gastric volume, ASA, and DMSA (p = 0.002 and p = 0.007, respectively). Oesophageal diameter above the conduit and an ASA to DMSA ratio ≤ 0.5 were negatively associated with AA (p = 0.008 and p = 0.08, respectively). Patients with improved outcomes after revisional bypass and gastrogastrostomy displayed a negative correlation with ASA and positive correlation with the ASA to PMSA ratio (≤ 0.5).

CONCLUSION

3DCT measurements have a potential role in defining post-LSG stenosis and predicting outcomes of revisional surgery. Patients with anatomic abnormalities that are shown on CT appear to improve with anatomic correction.

Concomitant Gastric Leak, Portal Vein Thrombosis, and Liver Abscesses Following Sleeve Gastrectomy: A Report of a Rare Case

One of the most serious complications after sleeve gastrectomy (SG) is a postoperative leak. Early diagnosis and treatment are essential due to potential secondary complications, such as sepsis, septic shock, and death. Less commonly known and rare complications include portal thrombosis and liver abscesses, which have been reported in only a few cases. Here, we present a patient who developed a leak, portal thrombosis, and concomitant liver abscesses, requiring both surgical and medical management, ultimately leading to a favorable outcome. To our knowledge, this is the first case report of these three concomitant complications in a patient in Mexico.

Efficacy of Omentopexy on Complications of Laparoscopic Sleeve Gastrectomy

BACKGROUND

Laparoscopic sleeve gastrectomy (LSG) is a commonly performed type of bariatric surgery. Early complications of LSG include bleeding, leakage, pulmonary embolism, and surgical site infections. Most surgeons try to implement preventive methods, such as omentopexy. Staple line-imbrication, which has a difficult learning curve, often prevents complications. This study aimed to evaluate the effect of omentopexy on patients with imbricated LSG.

MATERIAL AND METHODS

The study applied a retrospective data analysis design to patients who underwent LSG between 2020 and 2023. All patients' staple lines were imbricated, and patients were then divided into two groups: omentopexy group and control group. Patients' demographic features, such as age, gender, height, weight, body mass index(BMI), bleeding, leakage, and reoperations, were recorded and examined retrospectively.

RESULTS

A total of 1356 patients were included in the study (540 in omentopexy, 816 in control), of which the mean age was 37.9 ± 10.5 years, 82.3% were women, and mean BMI was 40.9 ± 5.8 kg/m2. The mean bleeding rate was 1.0% (1.3-0.7%), the mean leakage rate was 0.2% (0.2-0.2%, respectively), and the mean reoperation rate was 0.6% (0.7% and 0.5%, respectively). No statistically significant differences were observed.

CONCLUSION

Omentopexy is a technique that is widely used to prevent staple line complications. According to our study, omentopexy applied to an imbricated stapler line increased the operation time but did not affect bleeding or leakage ratios. This is the first study to evaluate the effect of omentopexy on imbricated staple lines. The findings of the study indicate that omentopexy has no additional benefit on early complications when using staple-line imbrication.

Acute Hiatal Hernia After Sleeve Gastrectomy: A Case Report

Obesity is considered the pandemic of this century. With the popularization of bariatric surgery due to its effectiveness, the number of procedures has significantly increased. One of the most performed surgeries is sleeve gastrectomy (SG). It is a safe procedure that rarely presents complications, with the most common being bleeding or staple line leaks. However, there are other less common complications or those that have been infrequently reported in the literature, such as acute hiatal hernia (AHH), which may require additional surgical intervention if it occurs. As the number of bariatric procedures performed worldwide increases, the likelihood of encountering these low-incidence complications also rises. The few cases reported in the literature describe different surgical techniques for this complication. The objective of this study is to describe the case of a female patient who developed AHH after undergoing SG, which was successfully treated with reduction and omentopexy in Mexico.

A Rare Encounter of Postoperative Abscess Not Linked to Staple Line in Sleeve Gastrectomy: A Case Report and Literature Review

Sleeve gastrectomy is a common bariatric procedure known for its safety and effectiveness, but postoperative complications like abscess formation, though rare, can occur. We report the case of a 37-year-old female who presented with atypical abdominal pain following a sleeve gastrectomy. Imaging revealed an abscess located away from the staple line. Surgical exploration and culture identified Streptococcus anginosus as the causative organism. This case emphasizes the importance of vigilant postoperative monitoring and early intervention to prevent complications. Proper management, including antibiotics and surgical drainage, is crucial for patient recovery.

Future Prospects of Metabolic and Bariatric Surgery: A Comprehensive Review

BACKGROUND

The field of metabolic and bariatric surgery (MBS) is currently an expanding surgical field with constant refinements in techniques, outcomes, indications, and objectives. MBS has been effectively applied across diverse patient demographics, including varying ages, genders, body mass indexes, and comorbidity statuses.

METHODS

We performed a comprehensive literature review of published retrospective cohort studies, meta-analyses, systematic reviews, and literature reviews from inception to 2024, reporting outcomes of MBS using databases such as PubMed, ScienceDirect, and Springer Link.

RESULTS

MBS is a safe and efficient therapeutic option for patients with obesity and associated medical conditions (mortality rate 0.03-0.2%; complication rates 0.4-1%). The favorable safety profile of MBS in the short-, mid-, and long-term offers the potential to treat patients with obesity and type 2 diabetes mellitus, immunosuppression, chronic anticoagulation, neoplastic disease, and end-organ failure without increased morbidity and mortality.

CONCLUSIONS

In conclusion, the future of MBS lies in the ongoing innovation and adapted therapeutic strategies along with the integration of a variety of other techniques for managing obesity. Careful preoperative assessments, coupled with a multidisciplinary approach, remain essential to ensure optimal surgical outcomes and patient satisfaction after MBS.

Update on comparison of laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass: a systematic review and meta-analysis of weight loss, comorbidities, and quality of life at 5 years

BACKGROUND

Laparoscopic Sleeve Gastrectomy (LSG) and Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) are the two most commonly performed bariatric surgeries for the treatment of obesity. This meta-analysis was performed with the aim of summarizing the available evidence on weight loss, remission of comorbidities, and quality of life in LRYGB and LSG, complementing the current literature.

METHODS

We searched PubMed, EMBASE and the Cochrane Library from January 2012 to June 2023 for randomized controlled trials and non-randomized interventional studies. We finally selected 18 eligible studies.

RESULTS

LRYGB resulted in greater weight loss compared with LSG at 5 years [WMD= -7.65 kg/m², 95% confidence interval (CI) -11.54 to -3.76, P = 0.0001], but there exists high heterogeneity with I²=84%. Resolution rate of type 2 diabetes mellitus (T2D) (OR = 0.60, 95%Cl 0.41-0.87, p = 0.007) and dyslipidemia (OR = 0.44, 95%Cl 0.23-0.84, p = 0.01) was higher in the LRYGB group than that in the LSG group at 5 years. There was no difference between LRYGB and LSG for remission of hypertension, and obstructive sleep apnea. No differences were observed in the QoL after LRYGB or LSG. Morbidity was lower in the LSG group (WMD = -0.07, 95% CI: -0.13, -0.02, P = 0.01) than in the LRYGB group. No statistically significant difference was found in mortality between the two procedures.

CONCLUSION

At 5 years after surgery, LRYGB resulted in greater weight loss and achieved better remission rate of T2D and dyslipidemia than LSG. However, LSG has a lower morbidity rate than that of LRYGB.

Propensity score matched analysis of laparoscopic revisional and conversional sleeve gastrectomy with concurrent hiatal hernia repair

INTRODUCTION

The primary aim of this study was to evaluate outcomes associated with concurrent hiatal hernia repair (CHHR) when performing a conversional or revisional vertical sleeve gastrectomy (VSG). CHHR is often necessary during VSG due to potential gastroesophageal reflux disease (GERD) development or obstructive symptoms.

METHODS

The Metabolic and Bariatric Surgery Accreditation and Quality Improvement (MBSAQIP) participant use file was assessed for the years 2015-2020 for revisional/conversional VSG procedures. The presence of CHHR was used to create two groups. Propensity score matching (PSM) was performed with E-analysis.

RESULTS

There were 33,909 patients available, with 5986 undergoing the VSG procedure with CHHR. In the unmatched analysis, there was an increased frequency of patients being female (85.72 vs 83.30%; p < 0.001), having a history of GERD (38.01 vs 31.25%; p < 0.001), and being of older age (49.59 ± 10.97 vs 48.70 ± 10.83; p < 0.001). Patients undergoing VSG with CHHR experienced decreased sleep apnea (25.00 vs 28.84%; p < 0.001) and diabetes (14.27 vs 17.80%; p < 0.001). PSM yielded 5986 patient pairs. Matched patients with CHHR experienced increased operative time (115 min ± 53 vs 103 min ± 51; p < 0.001), increased risk of postoperative pneumonia (0.45 vs 0.15%; p = 0.005) and readmission (4.69 vs 3.58%; p = 0.002) within thirty days. However, patients undergoing CHHR with revisional or conversional VSG did not experience increased risk of death, postoperative bleeding, postoperative leak, or reoperations.

CONCLUSION

Despite a small association with increased postoperative pneumonia, the rate of complications in patients undergoing laparoscopic revisional/conversional VSG and CHHR are low. CHHR is a safe option when combined with the laparoscopic revisional/conversional VSG procedure in the early postoperative period.

Primary Repair of Gastrobronchial Fistula Presenting 12 Years Post Uncomplicated Laparoscopic Sleeve Gastrectomy

Background

Obesity is an alarmingly increasing global public health issue. Laparoscopic sleeve gastrectomy (LSG) is the most common bariatric surgery owing to its simplicity, effectiveness, and low complication rates. The complications can be classified as early or late, with fistula formation being one of the most severe complications. Here, we report a rare gastrobronchial fistula (GBF) that presented 12 years post LSG.

Case Presentation

A 34-year-old woman who underwent LSG in 2011 was referred to our institution. The patient complained of recurrent upper respiratory tract infections, nausea, and vomiting. Abdominal computed tomography (CT) with oral contrast showed abnormal fistulous communication between the fundus and left lung. Conservative management was initiated but failed multiple times. After counseling the patient on the surgical options, she underwent fistula removal and primary repair of the fundus with a healthy omental wrap and an omental diaphragmatic flap. She tolerated the procedure well, recovered uneventfully, and was discharged on postoperative day 7.

Conclusion

GBF diagnosis is challenging. Imaging studies, such as CT and radiography with contrast and endoluminal diagnosis with esophagogastroduodenoscopy (EGD), bronchoscopy, and bronchial secretion analysis, aid in the diagnosis. GBF management requires a multidisciplinary team. Patients should be initially offered conservative management with the understanding that reoperation would be the only option if failure is seen for 3 months.

Incidence of Post-operative Gastro-esophageal Reflux Disorder in Patients Undergoing Laparoscopic Sleeve Gastrectomy: A Systematic Review and Meta-analysis

Gastroesophageal reflux disease (GERD) is a common concern following laparoscopic sleeve gastrectomy (LSG). This paper aimed to assess the incidence of reflux disease following these bariatric procedures. A literature search was conducted to identify observational studies and clinical trials reporting patients developed GERD disease after LSG. Twenty-two studies included in the analysis, involve 20,495 participants, indicated that the estimated proportion of patients who developed post-surgery GERD was 0.35 (95% CI 0.30-0.41). Subgroup analysis revealed a proportion of 0.33 (95% CI 0.27-0.38) in observational studies and 0.58 (95% CI 0.39-0.75) in clinical trials. High heterogeneity was noted across studies (I2 = 98%). Sensitivity analyses and publication bias assessments were performed to enhance the robustness of the results. Our findings highlight a moderate to high risk of developing GERD following LSG surgery.

Safety of Non-steroidal Anti-inflammatory Drugs as Part of Enhanced Recovery After Laparoscopic Sleeve Gastrectomy-A Systematic Review and Meta-Analysis

Laparoscopic sleeve gastrectomy (LSG) is an effective bariatric surgery option for managing extreme obesity in most patients. While non-steroidal anti-inflammatory drugs (NSAIDs) promise postoperative pain management after bariatric surgeries, their safety in LSG remains unexplored. In this systematic review, we studied the safety of NSAIDs following LSG reported by six studies involving 588 patients. Our study demonstrated that NSAIDs effectively alleviated the postoperative pain after LSG without major safety concerns. Most reported (>20% incidence) adverse events included postoperative nausea and vomiting (PONV, 21%). For patients undergoing LSG, NSAIDs offer a valuable option for pain management and improved care, potentially reducing opioid consumption. However, additional research is required to optimize NSAID usage and ensure safety, especially concerning renal and gastrointestinal issues.

Awareness of Bariatric Sleeve Gastrectomy Complications Among the General Population of Saudi Arabian Regions

Sleeve gastrectomy (SG) is a type of procedure called bariatric surgery that provides large weight loss and has a positive impact on diseases associated with obesity. However, it has brought several complications that have an impact on those undergoing surgery, which are classified into intraoperative and postoperative issues. The study's goal is to assess the Saudi Arabian population's awareness of SG consequences. This study assessed the general population's knowledge in Saudi Arabia in 2023 using a cross-sectional approach. The total number of participants was 1,013, the majority of whom were individuals between the ages of 18 and 25 (471, 46%), and females (692, 68%). A total of 692 (68%) participants showed awareness of BMI; in addition, 987 (97%) were aware of gastric sleeve surgery, and 538 (53%) understood its indications correctly. Regarding SG complications, approximately 821 (81%) of participants showed awareness. There were significant associations between knowledge of gastric sleeve surgery and residence in the northern region of Saudi Arabia. In conclusion, our study indicated that the general population is aware of the complications of gastric sleeve surgery, but it found a deficiency in their knowledge about BMI.

Recent advances in bariatric surgery: a narrative review of weight loss procedures

Bariatric surgery has emerged as a highly effective option for individuals with obesity, offering significant and sustainable weight loss outcomes. This surgical approach involves various procedures that alter the anatomy of the gastrointestinal tract, leading to reduced food intake and nutrient absorption. Established procedures such as sleeve gastrectomy, gastric bypass, adjustable gastric banding, and biliopancreatic diversion with duodenal switch have proven track records. In contrast, emerging options like intragastric balloons, AspireAssist devices, and endoscopic sleeve gastroplasty show promise but require further investigation. Numerous studies have highlighted the remarkable benefits of bariatric surgery, not only in weight loss but also in the resolution of obesity-related comorbidities and significant improvements in quality of life. However, successful outcomes rely on a multidisciplinary approach, encompassing preoperative evaluation, patient selection, comprehensive postoperative care, nutritional support, and psychological counseling. Regular follow-up and adherence to postsurgical recommendations are crucial for sustained weight loss and positive long-term results. As bariatric surgery continues to evolve, tailored procedures based on individual needs and ongoing research hold the potential for even more refined and effective approaches. Through this ongoing advancement, bariatric surgery is poised to offer improved patient outcomes, transforming lives for those grappling with the challenges of obesity.

Decision regret up to 6 years after sleeve gastrectomy

BACKGROUND

Sleeve gastrectomy (SG) is one of the most popular types of weight loss surgery today but is neither risk-free nor universally effective. We previously demonstrated that 5% of Roux-en-Y gastric bypass (RYGB) patients and up to 20% of gastric banding patients report overall regret 4 years after surgery. This study explores patients' attitudes toward their decision to have SG and decision regret rates up to 6 years postoperatively.

METHODS

We surveyed 185 patients who were at least 6 months post-SG (response rate 30%). We used a modified version of the Decision Regret Scale developed by Brehaut et al. We converted responses to a 0-100 scale so that higher scores (> 50) reflect greater regret. We characterized patients who expressed having overall decision regret (score > 50) vs. those who did not (≤ 50). Demographic and preoperative clinical information was extracted from the online medical records.

RESULTS

Of 185 SG patients, only 13 (7%) reported regret scores > 50 (i.e. high decision regret). Mean time from SG to survey completion was 41 months (range 6-76 months). Unadjusted comparisons between the two groups revealed that patients with high regret scores had lower mean weight loss (32.1% vs. 48.9% EBMIL), and reported less improvement in quality-of-life (QoL), such as physical health (46.2% vs. 93.5% "somewhat" or "significantly" improved). The two groups were similar in short-term complications, but those reporting overall regret were more likely to report GI complaints such as bloating (61.5% vs. 30.4%). Finally, patients with regret scores > 50 were more likely to be further out from SG (median time since surgery 61.8 vs. 41.1 months).

CONCLUSION

In our study, very few patients reported regret (7%) up to 6 years postoperatively, in line with prior reports after RYGB. Those with regret reported poorer QoL.

Endoscopic stent placement for the management of gastro-pleural and gastro-cutaneous fistula post laparoscopic sleeve gastrectomy: a case report

BACKGROUND

Gastro-pleural and gastro-cutaneous fistulae formation are rare yet life-threatening complications post-bariatric surgery. To our knowledge so far only limited cases of gastro-pleural and gastro-cutaneous fistulae post gastric sleeve surgery have been reported in the literature with their corresponding management. Therefore, we are reporting a case of placement of an endoscopic stent in the management of gastro-cutaneous fistula post laparoscopic sleeve gastrectomy.

CASE PRESENTATION

A 42 years old Pakistani, female morbidly obese patient, underwent laparoscopic sleeve gastrectomy. Within a week after the procedure, the patient presented with dyspnea. Workup showed a gastric leak for which percutaneous drain placement was done. Later, gastro-pleural and gastro-cutaneous fistulae were formed for which endoscopic fistula closure was done using a metallic stent.

CONCLUSION

Endoscopic stent placement is an emerging field and it is considered safe and effective for the management of complications related to bariatric surgery.

Risk Factors and Management Approaches for Staple Line Leaks Following Sleeve Gastrectomy: A Single-Center Retrospective Study of 402 Patients

Sleeve gastrectomy (SG) has gained ever-increasing popularity among laparoscopic surgeons involved in bariatric surgery. This single-institution, retrospective cohort study aims to evaluate the prevalence of postoperative staple line leakage (PSLL) after LSG and identify risk factors for its development. We included patient data that underwent LSG at our institution for a span of 17 years-starting in January 2005 and ending in December 2022. We set the investigation of correlations of patient-related factors (age, weight, BMI, smoking status, presence of diabetes mellitus) with the occurrence of postoperative leaks. A total of 402 patients were included in our study. Of them, 26 (6.46%) developed PSLL. In total, 19 (73%) patients underwent percutaneous drainage and 14 patients (53.8%) were treated with intraluminal endoscopic stenting. Finally, five patients (19.2%) were treated with endoscopic clipping of the defect. Operative management was required in only one patient. There were no statistically significant differences in patient age, mean weight at the time of operation, and mean BMI. Abnormal drain amylase levels were associated with earlier detection of PSLL. More consideration needs to be given to producing a consensus regarding the management of PSLL, prioritizing nonoperative management with the combination of percutaneous drainage and endoscopic stenting as the safest and most efficient approach.

Prevalence of Gastroesophageal Reflux Symptoms Post Sleeve Gastrectomy in Al-Qassim Region

BACKGROUND AND AIMS

After sleeve gastrectomy, heartburn sensation and regurgitation are frequent postoperative consequences. This study aimed to determine the prevalence and severity of heartburn sensation and regurgitation symptoms among patients who underwent sleeve gastrectomy, as well as the relationship between demographic variables and the presence and severity of these symptoms.

METHODOLOGY

This cross-sectional study included 290 patients who underwent sleeve gastrectomy in the Al-Qassim region, Saudi Arabia. Patients were asked to complete a questionnaire that assessed the presence and severity of heartburn and regurgitation symptoms. Demographic data, including age, gender, smoking status, and the date of bariatric surgery, were also collected.

RESULTS

The results showed that heartburn and regurgitation were common symptoms among patients who underwent sleeve gastrectomy, with 78% and 73.9% of patients reporting these symptoms, respectively. 11.5% of patients who experienced severe symptoms of regurgitation, and 6.4% of patients with severe heartburn reported serious symptoms that affected their lives by causing an inability to perform daily activities. Age and the date of bariatric surgery were significant factors associated with heartburn and regurgitation symptoms. Patients aged 25-35 years reported the highest prevalence of heartburn symptoms, and the more recent surgery; dated less than one year ago had the highest prevalence of heartburn symptoms.

CONCLUSION

Patients who have sleeve gastrectomy frequently experience heartburn and regurgitation, which can have a substantial influence on their quality of life. Routine evaluation and treatment of heartburn and regurgitation symptoms should be an integral component of postoperative care. Younger patients and those who undergo surgery in the early postoperative period may be at a greater risk for developing heartburn and regurgitation symptoms, necessitating more active measures to treat these symptoms.

Assessment of Lipid Balance Parameters after Laparoscopic Sleeve Gastrectomy in 1-Year Observation

Introduction: Currently, the increase in the percentage of obese people observed along with the development of civilization, reaching the level of a global pandemic, has forced a search for methods of effective and permanent obesity treatment. Obesity is a multifactorial disease; it coexists with many disease entities and requires multidisciplinary treatment. Obesity leads to metabolic changes in the form of metabolic syndromes, which include, among others, atherogenic dyslipidemia. The proven relationship between dyslipidemia and cardiovascular risk enforces the need to effectively improve the lipid profile of obese patients. Laparoscopic sleeve gastrectomy is a method of surgical treatment of morbid obesity which improves bariatric and metabolic parameters. The aim of the study was to assess the effectiveness of laparoscopic sleeve gastrectomy (LSG) at improving lipid profile parameters upon a 1-year follow up. Material and Methods: Bariatric parameters of 196 patients who underwent laparoscopic sleeve gastrectomy as well as the lipid profile of total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), non-NDL, and triglycerides (TG) in a 1-year observation were analyzed. Results: Improvements in bariatric parameters were observed in patients after LSG. Total cholesterol, low-density lipoprotein (LDL), triglycerides and non-HDL level decreases were observed along with an increase in high-density lipoprotein (HDL) cholesterol levels. Conclusions: Sleeve gastrectomy is an effective method of treating obesity and improving the lipid profile in obese patients.

Severe Cannabis use is Associated with Complications and Prolonged Length of Stay in Bariatric Surgery

PURPOSE

In the United States, recreational and medicinal cannabis use has continually increased in recent years, including in patients undergoing bariatric surgery. However, the effects of cannabis use on morbidity and mortality after bariatric surgery are uncertain, and the literature is limited by a paucity of studies. This study intends to evaluate the effects of cannabis use disorder on outcomes in patients undergoing bariatric surgery.

MATERIALS AND METHODS

The National Inpatient Sample 2016-2019 was queried for patients ≥ 18 years who underwent roux-en-y gastric bypass (RYGB), vertical sleeve gastrectomy (VSG), or adjustable gastric band (AGB) surgery. Cannabis use disorder was identified using ICD-10 coding. Three outcomes were evaluated: medical complications, in-hospital mortality, and length of stay. Logistic regression was used to evaluate effects of cannabis use disorder on medical complications and in-hospital mortality, and linear regression for length of stay. All models controlled for race, age, sex, income, procedure type, and various medical comorbidities.

RESULTS

A total of 713,290 patients were included in this study, with 1,870 (0.26%) having cannabis use disorder. Cannabis use disorder was associated with medical complications (OR: 2.24; 95% CI: 1.31-3.82; P = 0.003) and longer lengths of stay (β: 1.3; SE: 0.297; P < 0.001), but not in-hospital mortality (OR: 3.29; CI: 0.94-11.5); P = 0.062).

CONCLUSIONS

Severe cannabis use was associated with higher risk for complications and extended length of stay. Future investigations are needed to better elucidate the relationship between cannabis use and bariatric surgery, including effects of dosage, chronicity, and method of ingestion.

[Non-surgical treatment of staple-line suture leakage after redo sleeve gastrectomy]

Redo bariatric procedures are common. However, redo sleeve gastrectomy is not a frequent case of repeated bariatric surgery and can be performed rather as a necessary measure in difficult intraoperative conditions. We report a patient who underwent laparoscopic adjustable gastric band placement, its blockage and surgical removal, sleeve gastrectomy and redo sleeve gastrectomy. After that, staple-line suture failure developed that required endoscopic clipping.

Effects of Antibiotics on Weight in Obese Patients after Sleeve Gastrectomy

Obese patients can significantly reduce weight and have a positive impact on obesity-related diseases. However, the risk of infection complications in obese people is higher than that in normal people, especially the surgical site infection. This research investigates the effect of antibiotics on weight change of obese patients after laparoscopic sleeve gastrectomy (LSG). A retrospective analysis was performed on 131 morbidly obese patients or obese patients with complications who received LSG treatment in the Third Hospital of Shanxi Medical University from 2013 to 2020. Patients were separated into the antibiotic group (59 cases) and the normal group (72 cases) according to whether antibiotics were used after surgery. The differences of postoperative weight-related indexes, inflammation-related indexes, and short-term complications were compared between the two groups. At 12-month follow-up, the % excess weight loss (%EWL) in the antibiotic group was statistically abated than that in the normal group (92.99 ± 28.60, P < 0.01). In addition, the percentage of total weight loss (%total weight loss (%TWL)) was abated in the antibiotic group than in the normal group, but it was not significant (P > 0.05). White blood cell count and neutrophil count in the antibiotic group were statistically raised than those in the in normal group (P < 0.05), but neutrophil/lymphocyte ratio (NLR) showed no significant difference. Comparison of short-term postoperative complications between the two groups showed that the number of abdominal wall wound infection, body temperature > 38°C, and abdominal pain > 3 days in the antibiotic group were abated, but they were not statistically significant (P > 0.05). Short-term antibiotic exposure after sleeve gastrectomy had an adverse effect on postoperative weight loss, with no significant improvement in short-term complications.

Risk Factors for Early and Late Complications after Laparoscopic Sleeve Gastrectomy in One-Year Observation

BACKGROUND

Although laparoscopic sleeve gastrectomy (LSG) is considered a safe bariatric procedure in the treatment of obesity, it still involves a risk of developing postoperative complications. Knowledge of risk factors for possible complications would allow appropriate preoperative planning, optimization of postoperative care, as well as early diagnosis and treatment. The aim of this study was to evaluate risk factors for complications after laparoscopic sleeve gastrectomy.

METHODS

A retrospective study of 610 patients who underwent LSG at a tertiary institution were included in the study through retrospective analysis of the medical data. Complications were categorized as early (<30 days) and late (≥30 days) and evaluated according to the Clavien-Dindo Classification.

RESULTS

Early complications were observed in 35 patients (5.74%) and late complications occurred in 10 patients (1.64%). Independent risk factors of early complications after laparoscopic sleeve gastrectomy included hypercholesterolemia (OR 3.73; p-value = 0.023) and smoking (OR = 274.66, p-value < 0.001). Other factors that may influence the postoperative course are length of hospital stay and operation time. Smoking, peptic ulcer diseases and co-existence of hiatal hernia were found to be an independent predictors of late complications.

CONCLUSIONS

Smoking is associated with the higher risk of both, early and late complications, while hypercholesterolemia with only <30 days complications after laparoscopic sleeve gastrectomy.
