In any patient, the occurrence of postsplenectomy splenosis can complicate the planning of further surgeries. In our case, the gastric sleeve procedure was aborted, as it would have put the patient's life in danger. Therefore, only the gastric band was removed, eliminating future erosion. ...[more]

Project description:ImportanceFollowing the US Food and Drug Administration approval for laparoscopic gastric band surgery in 2001, as many as 96 000 devices have been placed annually. The reported rates of reoperation range from 4% to 60% in short-term studies; however, to our knowledge, few long-term population-level data on outcomes or expenditures are known.ObjectiveTo describe the rate of device-related reoperations occurring after laparoscopic gastric band surgery as well as the associated payments in a longitudinal national cohort.Design, settings, and participantsThis retrospective review of 25 042 Medicare beneficiaries who underwent gastric band placement between 2006 and 2013 identifies gastric band-related reoperations, including device removal, device replacement, or revision to a different bariatric procedure (eg, a gastric bypass or sleeve gastrectomy). The rates of reoperation were risk adjusted using a multivariable logistic regression model that included patient age, sex, race/ethnicity, Elixhauser comorbidities, and the year that the operation was performed.Main outcomes and measuresRate of device-related reoperation nationally and across individual hospital referral regions. Thirty-day total episode Medicare payments to hospitals for the index operation and any subsequent reoperations.ResultsOf the 25 042 patients who underwent gastric band placement, 20 687 (82.61%) were white, 18 143 (72.45%) were women, and the mean age was 57.56 years. Patients (mean age, 57.5; 76.2% women) requiring reoperation had lower rates of hypertension (64.9% vs 73.4%; P < .001) and diabetes (40.4% vs 44.6%; P < .001) and were more likely to have their index operation at a for-profit hospital (34.6% vs 22.0%; P < .001). With an average of 4.5-year follow-up, 4636 patients (18.5%) underwent 17 539 reoperations (an average of 3.8 procedures/patient). Hospital referral regions demonstrated a 2.9-fold variation in risk- and reliability-adjusted rates of reoperation (lower quartile average, 13.3%; upper quartile average, 39.1%). During the study period, Medicare paid $470 million for laparoscopic gastric band associated procedures, of which $224 million (47.6%) of the payments were for reoperations. From 2006 to 2013, the proportion of payments from Medicare for reoperations increased from 16.4% to 77.3% of their annual spending on the gastric band device.Conclusions and relevanceAmong Medicare beneficiaries undergoing gastric band surgery, device-related reoperation was common, costly, and varied widely across hospital referral regions. These findings suggest that payers should reconsider their coverage of the gastric band device.

Project description:Laparoscopic adjustable gastric banding (LAGB) is the third most popular bariatric procedure. Despite its reversibility and minimal invasiveness, band infection affects 1.2% of patients. We present a case of a 25-year-old, obese woman who was experiencing malaise and feverishness 3 years after gastric band placement. Due to port site infection the port was removed, which did not improve the patient's condition. After 2 years the band was removed via laparotomy with a minor surgical site infection reported. The patient returned 2 weeks after discharge with signs of sepsis. After ruling out pulmonary causes, an exploratory laparotomy was performed, revealing granulomatous peritonitis. Standard histopathological examinations, broncho-alveolar lavage culture and DNA tests along with microbiological cultures were inconclusive. Broad-spectrum antibiotics and antifungal and antiparasitic agents did not improve the patient's condition. Mycobacterium tuberculosis DNA was discovered in a greater omentum specimen. The patient was treated with isoniazid, rifampicin, pyrazinamide and streptomycin for four months.

Project description:Up to 10% of acute colonic diverticulitis may necessitate a surgical intervention. Although associated with high morbidity and mortality rates, Hartmann's procedure (HP) has been considered for many years to be the gold standard for the treatment of generalized peritonitis. To reduce the burden of surgery in these situations and as driven by the accumulated experience in colorectal and minimally-invasive surgery, laparoscopy has been increasingly adopted in the management of abdominal emergencies. Multiple case series and retrospective comparative studies confirmed that with experienced hands, the laparoscopic approach provided better outcomes than the open surgery. This technique applies to all interventions related to complicated diverticular disease, such as HP, sigmoid resection with primary anastomosis (RPA) and reversal of HP. The laparoscopic approach also provided new therapeutic possibilities with the emergence of the laparoscopic lavage drainage (LLD), particularly interesting in the context of purulent peritonitis of diverticular origin. At this stage, however, most of our knowledge in these fields relies on studies of low-level evidence. More than ever, well-built large randomized controlled trials are necessary to answer present interrogations such as the exact place of LLD or the most appropriate sigmoid resection procedure (laparoscopic HP or RPA), as well as to confirm the advantages of laparoscopy in chronic complications of diverticulitis or HP reversal.

Project description:Laparoscopic Gastric Plication (LGP) is a relatively new bariatric surgery procedure unique by not removing any part of the stomach. To bring new insights into the underlying molecular mechanism, we here present the first hypothesis-free analysis of the impact of LGP on the inflammatory and metabolic state as reflected by the serum proteome. A label-free quantitative shotgun proteomics approach was used to compare the serum proteome of 16 obese individuals before surgery with the serum of same individuals 1 to 2 months (timepoint T1) and 4 to 5 months (timepoint T2) post-surgery.

Project description:ObjectiveThe primary endpoints of this study were long-term weight loss, morbidity, and changes in comorbidities and quality of life.BackgroundBariatric surgery is an effective option for the treatment of severe obesity and its related comorbidities. However, few studies have reported on the long-term outcome (>5 yrs) of bariatric surgery.MethodsBetween 2002 and 2007, 250 patients with a body mass index (BMI) of 35 to 60 kg/m were randomly assigned to undergo laparoscopic gastric bypass or laparoscopic gastric banding. After exclusions, 111 patients underwent gastric bypass and 86 patients underwent gastric banding. Factors predictive of improved weight loss were analyzed using multiple logistic regressions.ResultsAt baseline, the mean age was 43 ± 10 years and the mean BMI was 46.5 ± 5.6 kg/m. At 10-year follow-up, the mean total body weight loss for the entire cohort was -37.5 ± 19.4 kg, -42.4 ± 19.6 kg for gastric bypass versus -27.4 ± 14.5 kg for gastric banding. Late reoperation was significantly higher after gastric banding compared with the gastric bypass group (31.4% vs. 8.1%, respectively, P < 0.01). For the entire cohort, improvement or remission of diabetes occurred in 68%; 61% for hypertension; and 57% for dyslipidemia. The long-term mortality for the entire cohort was 1.0% at a mean follow-up of 9.5 ± 0.4 years. Factors predictive of improved weight loss included the type of operation (ie, gastric bypass), female sex, and the absence of diabetes at baseline. At long-term follow-up, quality of life continues to be improved from baseline for both the groups.ConclusionsBariatric surgery is an effective treatment for severe obesity with durable 10-year weight loss and improvement in comorbidities and quality of life. Compared with gastric banding, gastric bypass was associated with better long-term weight loss, lower rate of late reoperation, and improved remission of comorbidities.

Project description:PurposeConventional straight-shaped laparoscopic surgical instruments have limitations that, unlike robotic surgery, the wrist joint cannot be used. This study aimed to analyze the short-term safety and feasibility of ArtiSential (Livsmed), a new articulating laparoscopic instrument, which obviates the limitations of conventional laparoscopic surgery and allows the wrist joint to be used freely over 360° as in robotic surgery.MethodsThe study included patients who underwent conventional laparoscopy or laparoscopy with the ArtiSential instrument. Patients who underwent laparoscopic gastrectomy for primary gastric adenocarcinoma in our institution were retrospectively reviewed. The groups were propensity score matched in a 11 ratio. Primary endpoint was incidence of early postoperative complication (postoperative 30-day morbidity and mortality) and secondary endpoints were operative outcomes.ResultsA total of 327 patients (147 of the conventional group and 180 of the ArtiSential group) were propensity score matched. After propensity score matching was performed, each group comprised of 122 patients. Both groups were comparable with regard to operation time, estimated blood loss, number of retrieved lymph nodes, and length of hospital stay. The ArtiSential group had a faster time to a fluid diet (2.6 ± 1.3 days vs. 2.3 ± 0.6 days, p = 0.015). There was no statistically significant difference in early postoperative complications between the two groups (the conventional group, 23.0%; the ArtiSential group, 26.2%; p = 0.656).ConclusionThe current study showed that the use of ArtiSential is a safe and feasible option without increasing operation time, length of hospital stay, and intraoperative bleeding.

Project description:BackgroundThe success of laparoscopic liver resection (LLR) depends on stable and full exposure of the parenchymal transection plane. We evaluated the efficacy of LLR using a silicone band retraction method for lesions in the anterolateral and posterosuperior segments.MethodsWe retrospectively analyzed 189 consecutive patients who had undergone LLR in our hospital between July 2010 and July 2020. They were divided into 2 groups according to whether LLR was performed before (conventional group; n=64) or after (silicone band group; n=125) the introduction of the silicone band retraction method.ResultsThe silicone band group demonstrated significantly less blood loss than that by the conventional group. The mean operative time and the hospital stay in the silicone band group were obviously shorter than that in the conventional group. The open conversion rate and the major complication rate were significantly lower in the silicone band group than that in the conventional group.ConclusionThe silicone band retraction method is a useful approach that results in a safe LLR.

Project description:Enterovesical fistula (EVF) is a relatively uncommon condition that is associated with severe morbidity. Minimally invasive and organ-preserving surgery should be performed in the case of EVF caused by benign diseases. We applied laparoscopic bladder-preserving surgery (LBPS) for EVF caused by benign gastrointestinal disease. Here, we report a surgical technique for LBPS. Patient and instrument port positioning are similar to those used in laparoscopic colorectal surgery. Dissection around the fistula is performed along the intestine as distant from the bladder as possible. If there is sufficient area around the intestinal portion of the fistula, it is isolated and resected using a linear stapler. If this approach is not possible, the intestinal fistula is sharply dissected as far away from the bladder as possible. LBPS for EVF was performed in 4 patients and included 3 direct sharp dissections and 1 stapling dissection. Three of the 4 patients did not require any further treatment for the bladder, and all procedures were feasibly accomplished under laparoscopic conditions. In conclusion, LBPS is feasible in cases of EVF caused by benign gastrointestinal disease, and we suggest that it should be the first choice of intervention in such cases.

Project description:BACKGROUND:Compared with open gastrectomy (OG), laparoscopic gastrectomy (LG) for gastric cancer has achieved rapid development and popularities in the past decades. However, lack of comprehensive analysis in long-term oncological outcomes such as recurrence and mortality hinder its full support as a valid procedure. Therefore, there are still debates on whether one of these options is superior. AIM:To evaluate the primary and secondary outcomes of laparoscopic versus open gastrectomy for gastric cancer patients METHODS: Two authors independently extracted study data. Risk ratio (RR) with 95% confidence interval (CI) was calculated for binary outcomes, mean difference (MD) or the standardized mean difference (SMD) with 95% CI for continuous outcomes, and the hazard ratio (HR) for time-to-event outcomes. Review Manager 5.3 and STATA software were used for the meta-analysis. RESULTS:Seventeen randomized controlled trials (RCTs) involving 5204 participants were included in this meta-analysis. There were no differences in the primary outcomes including the number of lymph nodes harvested during operation, severe complications, short-term and long-term recurrence, and mortality. As for secondary outcomes, compared with the OG group, longer operative time was required for patients in the LG group (MD?=?58.80?min, 95% CI?=?[45.80, 71.81], P?<?0.001), but there were less intraoperative blood loss (MD?=?-?54.93?ml, 95% CI?=?[-?81.60, -?28.26], P?<?0.001), less analgesic administration (frequency: MD?=?-?1.73, 95% CI?=?[-?2.21, -?1.24], P?<?0.001; duration: MD?=?-?1.26?days, 95% CI?=?[-?1.40, -?1.12], P?<?0.001), shorter hospital stay (MD?=?-?1.37?days, 95% CI?=?[-?2.05, -?0.70], P?<?0.001), shorter time to first flatus (MD?=?-?0.58?days, 95% CI?=?[-?0.79, -?0.37], P?<?0.001), ambulation (MD?=?-?0.50?days, 95% CI?=?[-?0.90, -?0.09], P?=?0.02) and oral intake (MD?=?-?0.64?days, 95% CI?=?[-?1.24, -?0.03], P?<?0.04), and less total complications (RR?=?0.81, 95% CI?=?[0.71, 0.93], P?=?0.003) in the OG group. There was no difference in blood transfusions (number, quantity) between these two groups. Subgroup analysis, sensitivity analysis, and the adjustment of Duval's trim and fill methods for publication bias did not change the conclusions. CONCLUSION:LG was comparable to OG in the primary outcomes and had some advantages in secondary outcomes for gastric cancer patients. LG is superior to OG for gastric cancer patients.
