INTRODUCTION: Esophageal surgery is an essential component of general surgery training and encompasses several types of cases that are logged by general surgery residents. There is a scarcity of data on the quality and volume of esophageal surgery experience during surgical residency in the United States. We analyzed trends for 9 different esophageal procedure categories logged by residents in the United States, with the aim to identify areas for improvement in training. METHODS: We conducted a retrospective analysis of operative case logs of all general surgery residents graduating from programs accredited by the ACGME over a fourteen-year period from 2009 to 2023. Data on mean esophageal cases reported by graduates, including mean in each procedure subcategory were retrieved. Cases were categorized as either surgeon chief or surgeon junior for each procedure category. Mann-Kendall trend test was used to obtain tau statistics and p-value for trends in mean operative surgical volume for the total number of cases in each operative category over the study period. Trends in surgeon chief and surgeon junior cases were also investigated for each operative category. RESULTS: The mean number of all esophageal procedures performed per resident during their training increased significantly from 10.5 in 2009 to 16 in 2022 (τâ¯=â¯0.833, p < 0.001). This trend observed among all esophageal procedures during this 14-year study can be largely attributed to the steady increase in the number and proportion of laparoscopic esophageal antireflux procedures performed (τâ¯=â¯0.950, p < 0.001). Additionally, esophagectomy procedures had a statistically significant, but modest, increase during the study period (τâ¯=â¯0.505, pâ¯=â¯0.023), from a mean of 1 case during training in 2009 to a peak of 1.3 in 2020. Although the general trend of esophagus procedures increased during the study period, most categories (7 out of 9) either decreased or did not significantly change. Esophagogastrectomy volume decreased significantly by 30%, from 1 per resident during their training in 2009 to 0.7 in 2022 (τâ¯=â¯-0.510, pâ¯=â¯0.018), esophageal diverticulectomy procedures decreased by 50% from 0.2 to 0.1 (τâ¯=â¯-0.609, pâ¯=â¯0.009), and operations for esophageal stenosis decreased by 75% from 0.4 to 0.1 (τâ¯=â¯-0.734, pâ¯=â¯0.001). Mean number of esophageal bypasses (τâ¯=â¯-0.128, pâ¯=â¯0.584), repair of perforated esophageal disease (τâ¯=â¯-0.333, pâ¯=â¯0.156), and other major esophagus procedures (τâ¯=â¯0.416, pâ¯=â¯0.063) did not significantly change. CONCLUSION: The operative volume of esophageal surgery that general surgery residents in the United States are exposed to has significantly risen over the past 14 years, largely driven by the increase in laparoscopic antireflux procedures. However, given the recent advances and the resultant heterogeneity in both esophageal surgery, the increase in resident operative volume is still inadequate to ensure the training of safe and adept esophageal surgeons, necessitating postresidency specialized training for trainees interested in esophageal surgery.

BACKGROUND: Postoperative internal hernias after Roux-en-Y gastric bypass (RYGB) have an incidence of 2%-9% and are a surgical emergency. Evidence on factors associated with length of stay (LOS) after emergent internal hernia reduction in RYGB patients is limited. METHODS: This is a retrospective review of patients who underwent internal hernia reduction after RYGB at our tertiary care center over a 5 year period from 2015 to 2020. Demographics, comorbidities, and intra- and postoperative hospital course were collected. Univariate and multivariate linear regressions were used to investigate factors associated with LOS. RESULTS: We identified 38 patients with internal hernia after RYGB. These patients with mean age 44.1 years were majority female (71.1%) and white race (60.5%). Of the 24 patients where the RYGB was done at our institution, the mean RYGB to IH interval was 43 months. Petersen's defect (57.8%) followed by jejuno-jejunal mesenteric defect (31.6%) were the most common locations for IH. Both Petersen's and jejuno-jejunal mesenteric hernias were found in 4 cases (10.5%). Revision of bypass and small bowel resection were required in 13.2% and 5.3% of cases, respectively. The median (interquartile range) length of stay (LOS) was 2 days. On the multivariate analysis, male sex (P = .019), conversion to exploratory laparotomy (P = .005), and resection of small bowel (P < .001) were independent risk factors for increased LOS. CONCLUSION: The most common location of IH after RYGB is Petersen's defect, followed by jejuno-jejunal mesenteric defect. LOS was significantly associated with male sex, exploratory laparotomy, and resection of small bowel.

BACKGROUND: Evidence shows that 14.2% of opioid-naive patients have long-term opioid dependence after bariatric surgery. Enhanced recovery after surgery (ERAS) protocols are widely used in bariatric surgery, while bariatric surgery targeting opioid prescriptions (BSTOP) protocols were recently introduced. We will investigate the combined impact of ERAS and BSTOP protocols after bariatric surgery. METHODS: We conducted a retrospective review for patients who underwent either a sleeve gastrectomy or Roux-en-Y gastric bypass at a tertiary care center. Pre-intervention and post-intervention data were compared. Primary outcomes were length of stay (LOS), 30-day readmission, 30-day complications, and discharge on opioids. Multivariate Poisson regression with robust standard error was used to analyze LOS. RESULTS: There was no significant difference in 30-day emergency room visits (3.3% vs. 4.0%; p value = 0.631), 30-day readmission (4.4% vs. 5.4%; p value = 0.577) or 30-day complication rate (4.2% vs. 6.4%; p value = 0.199). LOS was significantly lower in the post-intervention group; mean (interquartile range) 2 (1-2) days vs. 1 (1-2) day, p value < 0.001. On multivariate analysis, the post-intervention group had 0.74 (95% confidence interval 0.65-0.85; p value < 0.001) times lower LOS as compared to pre-intervention group. Patients with DM had a significantly longer LOS (relative risk: 1.22; p = 0.018). No other covariates were associated with LOS (p value < 0.05 for all). BSTOP analysis found a significant difference between the two groups. Discharge on opioids decreased from 40.6% pre-intervention to 7.1% post-intervention. CONCLUSION: ERAS and BSTOP protocols reduced length of stay and opioid need at discharge without an increase in complication or readmission rates.

Gastric bypass has grown in popularity in recent years due to its high efficacy in achieving long-term weight loss in patients with morbid obesity. Gastric bypass has been described to further exacerbate baseline nutritional deficiencies due to reduced gastric capacity and malabsorption. In rare cases, when protein deficiency is severe, Kwashiorkor disease may arise. The incidence of Kwashiorkor specifically following gastric bypass is rare, with an incidence of 4.7%. We report a case of a female patient who underwent a gastric bypass and subsequently developed Kwashiorkor. Physicians' suspicion of index for Kwashiorkor should be high for patients presenting with signs or symptoms of severe malnutrition following weight-loss procedures.
RESUMO
Superior mesenteric artery (SMA) syndrome, compression of the duodenum due to a decreased angle between the aorta and SMA, has a wide range of clinical presentations making it difficult to diagnose. Compression of the left renal vein is known as Nutcracker syndrome. We present the case of a 26-year-old male with a delayed diagnosis of SMA syndrome and Nutcracker phenomenon due to the patient's history of chronic pancreatitis. As a result of his obstruction and aspiration pneumonia, he was diagnosed with septic shock. The patient was treated for septic shock and maintained on an enteric diet with improvement in the body mass index and complete resolution of SMA syndrome symptoms.
RESUMO
Background and Objectives: Revisional bariatric surgery continues to increase. Laparoscopic adjustable gastric banding (LAGB) after previous Roux-en-Y gastric bypass (RYGB), known colloquially as "band-overpouch" has become an option despite a dearth of critically analyzed long-term data. Methods: Our prospectively maintained database was retrospectively reviewed for patients who underwent band-overpouch at our Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program Center of Excellence in a 18-year period ending October 31, 2021. We evaluated: demographics, comorbidities, operative procedures, and outcomes (30-day and > 30-day). Results: During the study period, of 4,614 bariatric procedures performed, 42 were band-overpouch with 39 (93%) being women. Overall, mean age was 49.8 years (range 26-75), a mean weight 251 pounds (range 141-447), and mean body mass index 42.4 (range 26-62). Comorbidities included: hypertension (n = 31; 74%), diabetes (n = 27; 64%), obstructive sleep apnea (n = 26; 62%), gastroesophageal reflux disease (n = 26; 62%), and osteoarthritis (n = 25; 60%). All procedures were performed laparoscopically with no conversions to open. Mean length of stay was 1.2 days (range 1-3). Mean follow-up time was 4.2 years (range 0.5-11). Mean excess weight loss was 14.9%, 24.3%, and 28.2% at 6 months, 1 year and ≥ 3 years, respectively. There was one 30-day trocar-site hematoma requiring transfusion. Long-term events included: 1-year (1 endoscopy for retained food; 1 internal hernia), 3-year (1 LAGB erosion; 1 LAGB explant), 4-year (1 anastomotic ulcer), 6-year (1 LAGB explant and Roux-en-Y revision), and 8-year (1 LAGB erosion). One 5-year mortality occurred (2.4%), in association with hospitalization for chronic illness and malnutrition. Band erosions were successfully treated surgically without replacement. Conclusion: Band-overpouch is associated with moderate excess weight loss and has good short-term safety outcomes.

Internal hernia is a rare cause of bowel obstruction in patients with no prior surgical history. Laparoscopic repair of a transverse bowel herniation through the foramen of Winslow is the rarest type of internal hernia, with only two case reports published in the literature. In a patient with a history with Crohn's disease and no prior surgical history, presenting with signs of bowel obstruction, and no inflammatory symptoms, internal hernia should be suspected as one of the causes. Minimally invasive laparoscopic repair is a feasible safe option in those patients, allowing patients to go home the next day postoperatively.
RESUMO
Inflammatory bowel disease (IBD) remains a topic of ongoing research given its prevalence, yet the pathogenesis and all clinical manifestations of the disease remain poorly understood. Giant inflammatory polyposis is one of the clinical manifestations of IBD that has rarely been described to the best of our knowledge. This is a recognized clinical entity, however, only a limited number of IBD associated cases have been described in literature to date. This phenomenon consists of numerous benign, inflammatory polyps that clump together giving the appearance of a larger mass, which may cause clinical colonic obstruction and radiographic findings mimicking colonic neoplasm. This clinical entity may present in 10-20% of patients with IBD.

PURPOSE: The transversus abdominis plane (TAP) block is a technique increasingly used for analgesia after surgery on the anterior abdominal wall. We undertook this study to determine the feasibility and analgesic efficacy of ultrasound-guided TAP blocks in morbidly obese patients. We describe the dermatomal spread of local anesthetic in TAP blocks administered, and test the hypothesis that TAP blocks decrease visual analog scale (VAS) scores. PATIENTS AND METHODS: After ethics committee approval and informed consent, 35 patients with body mass index >35 undergoing single-port sleeve gastrectomy (SPSG) were enrolled. All patients received balanced general anesthesia, followed by intravenous patient-controlled analgesia (IV-PCA; hydromorphone) postoperatively; all reported VAS >3 upon arrival to the recovery room. From the cohort of 35 patients having single-port laparoscopy (SPL), a sealed envelope method was used to randomly select ten patients to the TAP group and 25 patients to the control group. The ten patients in the TAP group received ultrasound-guided TAP blocks with 30 mL of 0.2% Ropivacaine injected bilaterally. The dermatomal distribution of the sensory block (by pinprick test) was recorded. VAS scores for the first 24 hours after surgery and opioid use were compared between the IV-PCA+TAP block and IV-PCA only groups. RESULTS: Sensory block ranged from T5-L1. Mean VAS pain scores decreased from 8 ± 2 to 4 ± 3 (P=0.04) within 30 minutes of TAP block administration. Compared with patients given IV-PCA only, significantly fewer patients who received TAP block had moderate or severe pain (VAS 4-10) after block administration at 6 hours and 12 hours post-surgery. However, cumulative consumption of hydromorphone at 24 hours after SPSG surgery was similar for both groups. CONCLUSION: Ultrasound-guided TAP blocks in morbidly obese patients are feasible and result in satisfactory analgesia following SPSG in the immediate postoperative period.
RESUMO
BACKGROUND: The goal of this study is to compare the outcomes of laparoscopic adjustable gastric banding (LAGB) and laparoscopic Roux-en-Y gastric bypass (LRYGB) in obese adolescents. METHODS: We performed a retrospective review of all adolescents between the ages of 15 and 19 who underwent LAGB or LRYGB at our university affiliated Bariatric Center of Excellence from 2002 to 2011. Postsurgical weight loss at 1, 3, 6, 12, 18, and 24 months was noted and expressed as percentage of excess weight loss (% EWL). RESULTS: Thirty-two patients underwent LRYGB and 23 underwent LAGB. The LAGB group was younger (18.6 ± 0.6 versus 17.2 ± 1.5) than the LRYGB group. Other preoperative demographic factors including body mass index, gender, ethnicity, and comorbidities were similar between the two groups. The average % EWL was superior in the LRYGB group compared to the LAGB group at all time points studied (p < 0.05), although at 2-year follow-up, only 16% (5/32) LRYGB and 30% (7/23) LAGB patients were available for follow-up. Three patients with type II diabetes mellitus underwent LRYGB and all experienced remission of their diabetes. The number of complications requiring interventions was similar between the two groups. CONCLUSIONS: In our study, adolescents undergoing LRYGB achieved superior weight loss compared to LAGB in the short-term follow-up. The complication rate for LAGB was similar compared to LRYGB. More studies are needed to monitor the long-term effects of these operations on adolescents before definitive recommendations can be made.
