RESUMO

BACKGROUND: Splenic preservation during a distal pancreatectomy (SPDP) may be performed with splenic vessel ligation, known as Warshaw's Technique (WT) or splenic vessel preservation (SVP). The consensus on which approach is best is divided. A systematic review of evidence in the literature was undertaken with the aim of analysing the merits and disadvantages of both WT and SVP. METHODS: A systematic search of medical literature from 1985-2011 was undertaken to identify all comparative studies and case series on SPDP. Non-English papers, series with < 5 patients, technical reports and reviews were excluded. The remaining articles were reviewed considering the study design, surgical technique, outcomes and complications. RESULTS: In 23 relevant studies, 356 patients underwent WT and 572 underwent SVP. In WT patients, the mean operating time (160 versus 215 min, P < 0.001), mean estimated blood loss (301 versus 390 ml, P < 0.001) and length of stay (8 versus 11 days, P < 0.001) was significantly less than the SVP patients, respectively. Considering complications, splenic infarction and splenectomy occurred more frequently in WT patients (P < 0.05). DISCUSSION: WT is technically easier to perform than SVP but has a higher incidence of subsequent splenectomies. Surgeons should be able to perform both procedures and tailor the technique according to the patient.

RESUMO

The aim of this meta-analysis was to assess whether treatment with ursodeoxycholic acid (UDCA) in patients who have undergone bariatric surgery reduces gallstone formation. A systematic literature search was performed using electronic databases (MEDLINE, Embase, CENTRAL, Web of Science, PROSPERO, Google Scholar and the WHO International Clinical Trials Registry platform). RCTs without restrictions on study language, year, status of publication and patient's age were used. Pooled risk ratios were calculated using a random-effects model. Subgroup analyses for drug dose, duration and procedure types were performed. Sensitivity analyses and a summary of findings table were generated to assess the robustness and the level of evidence provided, respectively. Fourteen trials were included (3619 patients, 2292 in UDCA vs 1327 in control group). Procedures included SG, RYGB, OAGB, AGB and Gastroplasty. UDCA dose ranged from 300 to 1200 mg per day. Gallstone formation occurred in 19.3% (8.3% in UDCA vs 38.1% in the control group). UDCA significantly reduced the risk of gallstone formation (14 trials, 3619 patients; RR 0.27, 95% CI 0.18-0.41; P < 0.001). UDCA significantly reduced the risk of symptomatic gallstone disease (6 trials, 2458 patients; RR 0.30, 95% CI 0.21-0.43; P < 0.001). No subgroup difference was found for different doses, duration and type of procedure performed. Oral UDCA treatment significantly reduces the risks of developing gallstones in postoperative bariatric patients from 38 to 8%. The use of 500 to 600 mg UDCA for 6 months is effective and should be implemented in all patients post-bariatric surgery.

RESUMO

OBJECTIVE: Postprandial hyperinsulinemic hypoglycemia with neuroglycopenia is an increasingly recognized complication of Roux-en-Y gastric bypass and gastric sleeve surgery that may detrimentally affect patient quality of life. One likely causal factor is glucagon-like peptide-1 (GLP-1), which has an exaggerated rise following ingestion of carbohydrates after bariatric surgery. This paper sought to assess the role of GLP-1 receptor agonists (GLP-1RAs) in managing postprandial hypoglycemia following bariatric surgery. METHODS: MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials.gov, and Scopus were systematically and critically appraised for all peer-reviewed publications that suitably fulfilled the inclusion criteria established a priori. This systematic review was developed according to the Preferred Reporting Items for Systematic Review and Meta-Analyses Protocols (PRISMA-P). It followed methods outlined in the Cochrane Handbook for Systematic Reviews of Interventions and is registered with PROSPERO (International Prospective Register of Systematic Reviews; identifier CRD420212716429). RESULTS AND CONCLUSIONS: Postprandial hyperinsulinemic hypoglycemia remains a notoriously difficult to manage metabolic complication of bariatric surgery. This first, to the authors' knowledge, systematic review presents evidence suggesting that use of GLP-1RAs does not lead to an increase of hypoglycemic episodes, and, although this approach may appear counterintuitive, the findings suggest that GLP-1RAs could reduce the number of postprandial hypoglycemic episodes and improve glycemic variability.

RESUMO

We report a rare silent migration of a fishbone into the liver and review the relevant literature. A 56-year-old man presented with a 2-day history of dull epigastric pain and raised inflammatory markers. Computerized tomography scan revealed a 4-cm abscess in the left lobe of the liver, with a linear radio-dense foreign body within the collection. At laparoscopy the hepatogastric fistula was disconnected. The fishbone was retrieved from the liver. Gastrostomy was closed with an omental patch. The patient had an uneventful recovery. Fifty-two cases of liver abscess secondary to enterohepatic fishbone migration were reported with over two-thirds presenting with a left-lobe abscess. There was marked variability in the management of liver abscess in the setting of fishbone migration-summarized in table. We believe that laparoscopic drainage of the abscess and extraction of the foreign body offer control of the source of sepsis and diminishes recurrence, whilst having a low-risk profile.

RESUMO

We present a frail 83-year-old female with Bouveret syndrome managed using an endoscopic approach. Our patient attended the emergency department with abdominal pain, vomiting and signs of sepsis. She had a recent admission with acute cholecystitis that which had been managed conservatively. Axial imaging revealed aerobilia with a 14 mm common bile duct and a 3.5 cm calculus impacted in the duodenum, in association with a cholecysto-duodenal fistula. After resuscitation, an oesphagoduodenoscopy was performed under general anaesthesia. The large stone was seen impacted in the first part of duodenum. Mechanical lithotripsy and the Kudo snare were employed to fragment the stone and remove large fragments. Bouveret syndrome is rarely managed with success through endoscopy. The syndrome typically occurs in frail, elderly co-morbid patients who would benefit from endoscopic management over open surgery. Despite low success rates historically, endoscopic management is a reasonable and viable option in cases of Bouveret syndrome.

RESUMO

BACKGROUND: Laparoscopic liver resection (LLR) is a highly demanding procedure with great variability. Previously published randomized trials have proven oncological safety of laparoscopic liver resection (LLR) as compared to open surgery. However, these were started after the learning curve (LC) was established. This leaves the question of whether the LC of LLR in the early laparoscopic era has affected the survival of patients with colorectal liver metastasis (CRLM). METHODS: All consecutive LLRs performed by a single surgeon between 2000 and 2019 were retrospectively analysed. A risk-adjusted cumulative sum (RA-CUSUM) chart for conversion rate and the log regression analysis of the blood loss identified two phases in the LC. This was then applied to patients with CRLM, and the two subgroups were compared for recurrence-free (RFS) and overall survival (OS). The analysis was repeated with propensity score-matched (PSM) groups. RESULTS: A total of 286 patients were included in the LC analysis, which identified two distinct phases, the early (EP; 68 patients) and the late (LP; 218 patients) phases. The LC was applied to 192 patients with colorectal liver metastasis (EPc, 45 patients; LPc, 147 patients). For patients with CRLM, R0 resection was achieved in 93 per cent: 100 per cent in the EPc group and 90 per cent in the LPc group (P = 0.026). Median OS and RFS were 60 and 16 months, respectively. The 5-year OS and RFS were 51 per cent and 32.7 per cent, respectively. OS (hazard ratio (h.r.) 0.78, 95 per cent confidence interval (c.i.) 0.51 to 1.2; P = 0.286) and RFS (h.r. 0.94, 95 per cent c.i. 0.64 to 1.37; P = 0.760) were not compromised by the learning curve. The results were replicated after PSM. CONCLUSION: In our experience, the development of a laparoscopic liver resection programme can be achieved without adverse effects on the long-term survival of patients with CRLM.

RESUMO

BACKGROUND: An increasing number of techniques are emerging in the literature describing single-incision laparoscopic cholecystectomy (SILC). The advent of a new surgical approach is a reminder of the increase in bile duct injuries in the past when laparoscopic cholecystectomy was first introduced. With this in mind, the authors describe a safe and reproducible approach to SILC. METHODS: Between August 2008 and August 2009, 20 patients with symptomatic gallbladder disease underwent SILC using a totally transumbilical fundus-first approach with an intraoperative cholangiogram. Data including pain scores were collected prospectively. RESULTS: In this initial series, the median operative time was 103 min (range, 55-177 min), including the time for two patients undergoing additional procedures at the time of surgery. Intraoperative cholangiograms were completed for 18 of 19 patients. Additional ports were required in four patients for safe completion of the procedure. The mean pain score 12 h postoperatively was 2.5 on a visual analogue scale with a range of 0-10. There was no morbidity or mortality. CONCLUSION: According to the findings, SILC with an intraoperative cholangiogram can be performed safely using a fundus-first approach. However, for SILC to become the operation of choice for the treatment of gallbladder disease, evidence is required to demonstrate its advantage over laparoscopic cholecystectomy.

RESUMO

Laparoscopic surgery via a single port is an evolving technique being applied to an increasing variety of operations [1]. Multiple series over the past 3 years have shown single-incision laparoscopic cholecystectomy to be feasible and safe [2]. The ergonomic difficulties of single-port laparoscopy include a loss of instrument triangulation and operation with camera and instruments in parallel. Many different modifications of techniques and equipment have been used to compensate. Single-port techniques have been applied by a few authors to laparoscopic nephrectomy [3], splenectomy [4], and obesity surgery [5, 6]. Laparoscopic liver resection is well established and shown to be safe in multiple series [7]. The laparoscopic approach is accepted as the gold standard for resection of segments 2 and 3 [8]. To the authors' knowledge, no reports of laparoscopic liver resection via a single port have been published. They report the use of their technique for single-incision laparoscopic left lateral segmentectomy in a patient with a solitary segment 2 colorectal liver metastasis. The authors maintained strict oncologic principles and adhered to their standard laparoscopic technique as far as possible. They used a TriPort (Advanced Surgical Concepts, Wicklow, Ireland) placed via a 12-mm incision at the umbilicus. Following diagnostic laparoscopy and intraoperative liver ultrasound, hepatic attachments were divided using electrocautery. Parenchymal transection and vascular control were achieved using an ultrasonic dissector and laparoscopic staplers. Standard straight laparoscopic instruments were used. A number of technical challenges were apparent. Movement of instruments was jerky at times, either because instruments were clashing with one another other or deflecting the camera. The multiport device can be stiff, requiring copious lubrication throughout surgery. Crossing hands facilitates internal triangulation of the operating instruments to allow retraction or to apply tension, for example, during the division of hepatic attachments. Control of minor hemorrhage is possible with judicious and patient application of pressure using small pieces of surgical gauze. An articulating laparoscopic stapler is useful to achieve the ideal angle of staple deployment during transection of vascular pedicles. The specimen was extracted by extending the umbilical incision. No complications occurred. The patient was able to resume an oral diet and full mobility free of opioid analgesia on the first postoperative day. The resection margin was clear. This video demonstrates that the authors' technique is feasible and oncologically safe for selected patients requiring liver resection.

RESUMO

Women with obesity are at risk of pelvic floor dysfunction with a 3-fold increased incidence of urge urinary incontinence (UUI) and double the risk of stress urinary incontinence (SUI). The National Institute for Health and Care Excellence (NICE) and European Association of Urology (EAU) recommend that women with a body mass index ≥30 kg/m2 should consider weight loss prior to consideration for incontinence surgery. This systematic review and meta-analysis will assess this recommendation to aid in the counselling of women with obesity-related urinary incontinence (UI). Medical Literature Analysis and Retrieval System online (MEDLINE), EMBASE, Cochrane, ClinicalTrials.gov, and SCOPUS were systematically and critically appraised for all peer reviewed manuscripts that suitably fulfilled the inclusion criteria established a priori and presented original, empirical data relevant to weight loss intervention in the management of urinary incontinence. Thirty-three studies and their outcomes were meta-analysed. Weight loss interventions were associated in a decreased prevalence in UI (OR 0.222, 95% CI [0.147, 0.336]), SUI (OR 0.354, 95% CI [0.256, 0.489]), UUI (OR 0.437, 95% CI [0.295, 0.649]) and improved quality of life (PFDI-20, SMD -0.774 (95% CI [-1.236, -0.312]). This systematic review and meta-analysis provide evidence that weight loss interventions are effective in reducing the prevalence of obesity-related UI symptoms in women. Bariatric surgery in particular shows greater sustained weight loss and improvements in UI prevalence. Further large scale, randomized control trials assessing the effect of bariatric surgery on women with obesity-related UI are needed to confirm this study's findings.

RESUMO

INTRODUCTION: Ten percent of cirrhotic patients are known to have a high risk of postoperative complications. Ninety percent of bariatric patients suffer from non-alcoholic fatty liver disease (NAFLD), and 50% of them may develop non-alcoholic steatohepatitis (NASH) which can progress to cirrhosis. The aim of this study was to assess whether the presence of cirrhosis at the time of bariatric surgery is associated with an increased rate and severity of short- and long-term cirrhotic complications. METHODS: A cohort of 110 bariatric patients, between May 2003 and February 2018, who had undergone liver biopsy at the time of bariatric surgery were reassessed for histological outcome and divided into two groups based on the presence (C, n = 26) or absence (NC, n = 84) of cirrhosis. The NC group consisted of NASH (n = 49), NAFLD (n = 24) and non-NAFLD (n = 11) liver histology. Medical notes were retrospectively assessed for patient characteristics, development of 30-day postoperative complications, severity of complications (Clavien-Dindo (CD) classification) and length of stay. The C group was further assessed for long-term cirrhosis-related outcomes. RESULTS: The C group was older (52 years vs 43 years) and had lower BMI (46 kg/m2 vs 52 kg/m2) and weight (126 kg vs 145 kg) compared to the NC group (p < 0.05). The C group had significantly higher overall complication rate (10/26 vs 14/84, p < 0.05) and severity of complications (CD class ≥ III, 12% vs 7%, p < 0.05) when compared to the NC group. The length of stay was similar between the two groups (5 days vs 4 days). The C group had significant improvement in model end-stage liver disease scores (7 vs 6, p < 0.01) with median follow-up of 4.5 years (range 2-11 years). There were no long-term cirrhosis-related complications or mortality in our studied cohort (0/26). CONCLUSION: Bariatric surgery in cirrhotic patients has a higher risk of immediate postoperative complications. Long-term cirrhosis-related complications or mortality was not increased in this small cohort. Preoperative identification of liver cirrhosis may be useful for risk stratification, optimisation and informed consent. Bariatric surgery in well-compensated cirrhotic patients may be used as an aid to improve long-term outcome.

RESUMO

Obesity is an ever growing pandemic and a prevalent problem among men of reproductive age that can both cause and exacerbate male-factor infertility by means of endocrine abnormalities, associated comorbidities, and direct effects on the precision and throughput of spermatogenesis. Robust epidemiologic, clinical, genetic, epigenetic, and preclinical data support these findings. Clinical studies on the impact of medically induced weight loss on serum testosterone concentrations and spermatogenesis is promising but may show differential and unsustainable results. In contrast, literature has demonstrated that weight loss after bariatric surgery is correlated with an increase in serum testosterone concentrations that is superior than that obtained with only lifestyle modifications, supporting a further metabolic benefit from surgery that may be specific to the male reproductive system. The data on sperm and semen parameters is controversial to date. Emerging evidence in the burgeoning field of genetics and epigenetics has demonstrated that paternal obesity can affect offspring metabolic and reproductive phenotypes by means of epigenetic reprogramming of spermatogonial stem cells. Understanding the impact of this reprogramming is critical to a comprehensive view of the impact of obesity on subsequent generations. Furthermore, conveying the potential impact of these lifestyle changes on future progeny can serve as a powerful tool for obese men to modify their behavior. Healthcare professionals treating male infertility and obesity need to adapt their practice to assimilate these new findings to better counsel men about the importance of paternal preconception health and the impact of novel non-medical therapeutic interventions. Herein, we summarize the pathophysiology of obesity on the male reproductive system and emerging evidence regarding the potential role of bariatric surgery as treatment of male obesity-associated gonadal dysfunction.

RESUMO

BACKGROUND: Its a dilemma to attempt a palliative procedure to debulk the tumour and/or prevent future obstructive complications in a locally advanced intra abdominal malignancy. CASE PRESENTATION: A 38 year old Vietnamese man presented with a carcinoma of the colon which had invaded the gallbladder and duodenum with a sealed perforation of the second part of the duodenum. Following surgical exploration, it was evident that primary closure of the perforated duodenum was not possible due to the presence of unresectable residual tumour. CONCLUSION: We describe a novel technique using a covered duodenal stent deployed at open surgery to aid closure of a malignant duodenal perforation.

RESUMO

BACKGROUND: Laparoscopic liver surgery is becoming increasingly common. This cohort study was designed to directly compare perioperative outcomes of the left lateral segmentectomy via laparoscopic and open approach. METHODS: Between 2002 and 2006 43 left lateral segmentectomies were performed at King's College Hospital. Those excluded from analysis included previous liver resections, polycystic liver disease, liver cirrhosis and synchronous operations. Of 20 patients analysed, laparoscopic (n = 10) were compared with open left lateral segmentectomy (n = 10). Both groups had similar patient characteristics. RESULTS: Morbidity rates were similar with no wound or chest infection in either group. The conversion rate was 10% (1/10). There was no difference in operating time between the groups (median time 220 minutes versus 179 minutes, p = 0.315). Surgical margins for all lesions were clear. Less postoperative opiate analgesics were required in the laparoscopic group (median 2 days versus 5 days, p = 0.005). The median postoperative in-hospital stay was less in the laparoscopic group (6 days vs 9 days, p = 0.005). There was no mortality. CONCLUSION: Laparoscopic left lateral segmentectomy is safe and feasible. Laparoscopic patients may benefit from requiring less postoperative opiate analgesia and a shorter post-operative in-hospital stay.

RESUMO

BACKGROUND: In bariatric surgery, preoperative very low-calorie diets (VLCD) may better meet the technical demands of surgery by shrinking the liver. However, diets may affect tissue healing and influence bowel anastomosis in an as-yet-undefined manner. OBJECTIVE: This randomized controlled trial aimed to examine the effect on collagen deposition in wounds in patients on a 4-week VLCD before laparoscopic gastric bypass. SETTING: University hospital. METHODS: The trial was undertaken in patients undergoing laparoscopic Roux-en-Y gastric bypass, with a control group (n = 10) on normal diet and an intervention group (n = 10) on VLCD (800 kcal) for 4 weeks. The primary outcome measured was expression of collagen I and III in skin wounds, with biopsies taken before and after the diet and 7 days postoperatively as a surrogate of anastomotic healing. Secondary outcome measures included liver volume and fibrosis score, body composition, operating time, blood loss, hospital stay, and complications. RESULTS: Patients in both groups were similar in age, sex, body mass index (53.4 versus 52.8 kg/m2), co-morbidities, liver volume, and body composition. Expression of mature collagen type I was significantly decreased in diet patients compared with controls after 4 weeks of diet and 7 days after surgery. This was significant decrease in liver volume (23% versus 2%, P = .03) but no difference in operating times (129 versus 139 min, P = .16), blood loss, length of stay, or incidence of complications. CONCLUSIONS: Preoperative diets shrink liver volume and decrease expression of mature collagen in wounds after surgery. Whether the latter has a detrimental effect on clinical outcomes requires further evaluation.

RESUMO

BACKGROUND: Obesity surgery mortality risk scoring system (OS-MRS) classifies patients into high, intermediate and low risk, based on age, body mass index, sex and other comorbidities such as hypertension and history of pulmonary embolism. High-risk patients not only have a higher mortality but are more likely to develop post-operative complications necessitating intervention or prolonged hospital stay following bariatric surgery. Endoscopically placed duodenal-jejunal bypass sleeve (Endobarrier) has been designed to achieve weight loss and improve glycaemic control in morbidly obese patients with clinically proven effectiveness. The aim of this study was to assess if pre-operative insertion of endobarrier in high-risk patients can decrease morbidity and length of stay after bariatric surgery. MATERIALS AND METHODS: Between 2012 and 2014, a cohort of 11 high-risk patients had an Endobarrier inserted (E&BS group) for 1 year prior to definitive bariatric surgery. These patients were compared against a similar group undergoing primary bariatric surgery (PBS group) during same duration. The two groups were matched for age, gender, body mass index, comorbidities, surgical procedure and OS-MRS using propensity score matching. Outcome measures included operative time, morbidity, length of stay, intensive therapy unit (ITU) stay, readmission rate, percentage excess weight loss (%EWL) and percentage total weight loss (%TWL). RESULTS: Patient characteristics and OS-MRS were similar in both groups (match tolerance 0.1). There was no significant difference in total length of stay, readmission rate, %EWL and %TWL. Operative time, ITU stay, post-operative complications and severity of complications were significantly less in the E&BS group (p < 0.05) with significant likelihood of planned ITU admissions in the PBS group (p < 0.05). CONCLUSION: Endobarrier could be considered as a pre bariatric surgical intervention in high-risk patients. It may result in improved post-operative outcomes in high-risk bariatric patients.

RESUMO

Iatrogenic nerve injuries have been rarely reported following laparoscopic abdominal surgeries. These can be serious complications with the potential for long-term disability. We present a rare case of bilateral sciatic nerve palsy following laparoscopic sleeve gastrectomy on a super-super-obese male with BMI 78.04 kg/m2. The procedure was completed laparoscopically in 7 hours duration, and in spite of adequate precautions, he developed bilateral sciatic nerve palsy. Nerve conduction studies showed denervation of L5/S1 confirming the diagnosis. The patient showed gradual recovery with physiotherapy, and at 18 months follow-up he was mobilizing without any walking aids, with BMI 47.34 kg/m2. Compressive nerve injuries following prolonged laparoscopic operations should be included in the list of procedural complications, especially in morbidly obese patients where the risk is significantly higher.

RESUMO

BACKGROUND: Factors leading to weight loss and weight stabilization after bariatric surgery are not fully understood. The aims of this study were to develop an animal model for biliopancreatic diversion (BPD) and to determine changes in gut hormones, malabsorption and small bowel histology postoperatively. METHODS: 2 groups of Wistar rats underwent sham and BPD surgery. Daily postoperative weights and food intake were measured. 24-hour fecal collections were performed at Day 6 and 21. Bomb calorimetry was performed to determine the fecal calorific values. At day 23, levels of peptide YY (PYY), glucagon-like peptide 1 (GLP-1) and glucagon-like peptide 2 (GLP-2) were determined and small bowel biopsies were taken. RESULTS: Animals in the BPD group had significant reduction in weight (P<0.001) and in food intake (P<0.001) compared to the sham group. Serum levels of PYY, GLP-1 and GLP-2 in the BPD group were significantly higher (P<0.005). Animals in the BPD group had significantly higher fecal energy content at Day 6 (P<0.001) but not at Day 21 when compared to the sham group. Small bowel histology confirmed the presence of significantly increased mitosis (P=0.03) and labelled cells (P=0.002) in the BPD animals when compared to sham. CONCLUSIONS: In our animal model, the higher levels of PYY, GLP-1 and GLP-2 after BPD may be due to gut adaptation and hypertrophy and could be important in inducing and maintaining weight loss after bariatric surgery.

RESUMO

INTRODUCTION: Laparoscopy is increasingly utilised as a diagnostic tool in management of abdominal trauma; however its role in therapeutic intervention remains unexplored. The aim of this study is to compare laparoscopy with laparotomy in the treatment of abdominal trauma in haemodynamically stable patients. METHODS: A review of patients undergoing surgery for abdominal trauma between January 2004-2014 identified 25 patients who underwent laparoscopy for therapeutic intervention (TL). This group was matched with 25 similar patients undergoing laparotomy (LT). Matching of the two cohorts was based on patient characteristics, severity of injuries, haemodynamic compromise and radiological findings. Peri-operative outcomes were compared. DISCUSSION: Patient characteristics were similar in TL and LT patients for age (median 33 vs. 26 years), gender distribution and clinical presentation. Injury severity score was also similar with a median of 16 in both groups (major trauma = ISS>15, normal range 0-75). Types of injuries included; hollow viscus [bowel repair = 10 (TL) vs. 16 (LT)] and solid organs [5(TL) vs. 2 (LT)]. Median operating time was similar in both groups; 105(TL) compared to 98 (LT) minutes. Post-operative complications (1 vs. 10, p = 0.02), analgesia requirements, specifically opiate use (34 vs. 136 morphine equivalents, p = 0.002) and hospital stay (4 vs. 9 days, p = 0.03) were significantly lower in the laparoscopy group. CONCLUSIONS: Abdominal trauma in haemodynamically stable patients can be managed effectively and safely with laparoscopy by experienced surgeons. Major benefits may include lower morbidity, reduced pain, and shorter length of hospital stay.
