RESUMO
BACKGROUND: The COVID-19 pandemic created delays in surgical care. The population with obesity has a high risk of death from COVID-19. Prior literature shows the most effective way to combat obesity is by weight loss surgery. At different times throughout the COVID-19 pandemic, elective inpatient surgeries have been halted due to bed availability. Recognizing that major complications following bariatric surgery are extremely low (bleeding 0-4%, anastomotic leaks 0.8%), we felt outpatient bariatric surgery would be safe for low-risk patients. Complications such as DVT, PE, infection, and anastomotic leaks typically present after 7 days postoperatively, well outside the usual length of stay. Bleeding events, severe postoperative nausea, and dehydration typically occur in the first few days postoperatively. We designed a pathway focused on detecting and preventing these early post-op complications to allow safe outpatient bariatric surgery. METHODS: We used a preoperative evaluation tool to risk stratify bariatric patients. During a 16-month period, 89 patients were identified as low risk for outpatient surgery. We designed a postoperative protocol that included IV hydration and PO intake goals to meet a safe discharge. We sent patients home with a pulse oximeter and had them self-monitor their pulse and oxygen saturation. We called all patients at 10 pm for a postoperative assessment and report of their vitals. Patients returned to clinic the following day and were seen by a provider, received IV hydration, and labs were drawn. RESULTS: 80 of 89 patients (89.8%) were successfully discharged on POD 0. 3 patients were readmitted within 30 days. We had zero deaths in our study cohort and no morbidity that would have been prevented with postoperative admission. CONCLUSION: We demonstrate that by identifying low-risk patients for outpatient bariatric surgery and by implementing remote monitoring of vitals early outpatient follow-up, we were able to safely perform outpatient bariatric surgery.

AIM: Bariatric surgery induces significant weight loss, increases insulin sensitivity, and reduces mortality, but the underlying mechanisms are not clear. It was hypothesized that Roux-en-Y gastric bypass (RYGB) surgery improves metabolic profile along with weight loss. The objective of this pilot study was to evaluate changes in serum metabolites and fatty acids (FA) at 2 weeks and 6 months after RYGB. MATERIALS AND METHODS: Serum samples were collected pre-surgery, at 2 weeks and 6 months post-surgery from 20 patients undergoing RYGB surgery. Serum non-esterified free FA (NEFA) were measured. Serum metabolites and FA were measured using nuclear magnetic resonance spectroscopy and improved direct fatty acid methyl ester synthesis and the gas chromatography/mass spectrometry method, respectively, in subjects who completed follow-up at 6 months (n = 8). RESULTS: Mean (standard deviation) percent total weight loss was 6.70% (1.7) and 24.91% (6.63) at 2 weeks (n = 15) and 6 months (n = 8) post-surgery, respectively. NEFA were significantly reduced at 6 months post-surgery (P = 0.001, n = 8). Serum branched chain amino acids, 2-aminobutyrate, butyrate, 2-hydroxybutyrate, 3-hydroxybutyrate, acetone, 2-methylglutarate, and 2-oxoisocaproate were significantly reduced, while serum alanine, glycine, pyruvate, and taurine were significantly elevated at 6 months post-surgery compared with pre-surgery (n = 8, P < 0.05). Also, serum FA C10:0, C13:0, C14:0, C15:0, and C18:0 increased significantly (n = 8, P < 0.05) by 6 months post-surgery. CONCLUSIONS: Changes in serum metabolites and FA at 6 months post-RYGB surgery in this pilot study with limited number of participants are suggestive of metabolic improvement; larger studies are warranted for confirmation.

General surgery in the rural hospital is threatened by declining resident interest in pursuing a career in the rural setting. We found that by initiating a rural rotation of 3 months in the senior resident years, a case mix that more approximated that of the rural surgeons was experienced. Also, by experiencing a rural rotation, more residents chose to practice in a rural setting when compared with residents before the initiation of the rotation.

Minimally invasive surgery has found many applications in general surgery. The role of laparoscopy in trauma has been debated as a diagnostic, as well as therapeutic, tool in hemodynamically stable patients. This study evaluated laparoscopy in the trauma population. A retrospective review of all laparoscopies performed in hemodynamically stable trauma patients from 1996 until 2006 was conducted. Mechanisms of injury, perioperative data, and demographic variables were analyzed using descriptive statistics and Student's t test. Exploratory diagnostic laparoscopy was performed on 102 patients. Laparoscopy was negative for 65 per cent of patients; 12 per cent of these were converted to laparotomy due to adhesions, hemoperitoneum, or surgeon preference. None of the conversions revealed intra-abdominal injury at laparotomy. An injury was diagnosed at laparoscopy in the remaining 35 per cent, with 55 per cent conversion rate to repair the injury. Therapeutic laparoscopy included serosal repair, hemorrhage control, diaphragmatic repair, and other standard laparoscopic treatments. No patient required re-exploration, there were no missed injuries or other complications, and no patient died in this study. Laparoscopy has an important diagnostic and therapeutic role in selected hemodynamically stable trauma patients. Using a minimally invasive approach can reduce the potential morbidity of negative laparotomy.

Laparoscopic appendectomy (LA) is safe and effective in cases of peritonitis, perforation, and abscess. We investigated our conversion rate and clinical outcomes in this patient population, as well as preoperative factors that predict operative conversion. A retrospective nonrandomized cohort of 92 patients underwent LA for acute appendicitis with peritonitis, perforation, or abscess at our institution between 1997 and 2002. Thirty-six of the 92 were converted to open appendectomy (OA), yielding a conversion rate of 39 per cent. The presence of phlegmon (42%), nonvisualized appendix (44%), technical failures (8%), and bleeding (6%) were reasons for conversion. Preoperative data had no predictive value for conversion. CT scan findings of free fluid, phlegmon, and abscess did not correlate with findings at the time of surgery. Total complication rates were 8.9 per cent in the LA group as compared to 50 per cent in the converted cohort. Postoperative data showed LA patients stayed 3.2 days versus 6.9 days for converted patients (P = 0.01). LA patients had less pneumonia (P = 0.02), intra-abdominal abscess (P = 0.01), ileus (P = 0.01), and readmissions (P = 0.01). LA is safe and effective in patients with appendicitis with peritonitis, perforation, and abscess, resulting in shorter hospital stays and less complication.

Minimally invasive parathyroidectomy (MIP) guided by preoperative sestamibi scanning has been shown to reduce operative time, hospital stay, and cost in treating primary hyperparathyroidism. However, controversy exists over routine preoperative sestamibi scanning. The purpose of this study was to determine the utility of sestamibi scanning at our institution as part of the MIP protocol and to analyze calcium and parathyroid hormone levels as possible predictors of successful sestamibi scanning. Charts of 37 consecutive patients undergoing MIP at our institution were reviewed, and age, sex, preoperative calcium, and parathyroid (PTH) levels, invasiveness of procedure, and pathologic diagnosis were recorded. Sestamibi scans were reviewed and scored by 4 nuclear medicine faculty based on the level of suspicion for parathyroid adenoma. Neither calcium nor PTH correlated significantly with sestamibi scan score (Spearman coefficient, r = 0.075, P = 0.67 and r = 0.277, P = 0.10, respectively). Receiver-operating-characteristic (ROC) analysis showed sestamibi scanning to have sensitivity and specificity in predicting MIP completion (87% and 68%). Logistic regression showed only sestamibi scan (P = 0.038), not calcium or PTH (P = 0.977 and P = 0.767) to be predictive of MIP completion. In conclusion, sestamibi scanning effectively predicted the ability to perform MIP. However, preoperative calcium and PTH predicted neither sestamibi scan results nor completion of MIP.

The purpose of this study was to investigate whether hand-assisted laparoscopic radical nephrectomy (HALN) has benefits over the traditional transabdominal radical nephrectomy. More specifically we focused on the use of the hand-assisted technique as a definitive oncologic procedure for renal cancers. This study is a retrospective nonrandomized study comparing 12 hand-assisted laparoscopic radical nephrectomies with 12 transabdominal radical nephrectomies. All patients included in the study had the preoperative diagnosis of renal mass. HALN population averaged 1.83 +/- 1.64 (mean +/- standard deviation) major comorbidities versus 1.08 +/- 0.8 open (P = 0.032). The HALN OR time averaged 103 +/- 32.8 versus 57 +/- 18.3 minutes open (P = 0.001). The estimated blood loss mean for HALN was 83 versus 318 cm3 open (P = 0.001). Length of stay for HALN was 4.9 +/- 2.2 versus 5.9 +/- 2.9 days (P = 0.35). Days to regular diet was 2.9 +/- 2.3 in HALN versus 3.5 +/- 2.11 open (P = 0.52). Days of intravenous pain medications were 1.8 +/- 0.72 HALN versus 3.0 +/- 1.28 open (P = 0.016). Postoperative complication rates for the two groups were identical: two of 12 (ileus and post-operative bleeding). Tumor size mean was 6.8 +/- 2.99 cm for HALN versus 4.2 +/- 1.29 cm open (P = 0.012). Tumor margins were negative for 12 of 12 in HALN versus 11 of 12 open. Selection bias (selecting ailing patients to the HALN cohort) diminished the statistical significance of our postoperative recovery data. It is likely that a prospectively randomized study with a larger population may prove the hand-assisted approach equal if not superior to the open technique. The use of HALN in patients with renal tumors is an effective alternative to traditional transabdominal radical nephrectomy.
