RESUMEN
The surgical management of obesity in Hong Kong has rapidly evolved over the past 20 years. Despite increasing public awareness and demand concerning bariatric and metabolic surgery, service models generally are not standardised across bariatric practitioners. Therefore, a working group was commissioned by the Hong Kong Society for Metabolic and Bariatric Surgery to review relevant literature and provide recommendations concerning eligibility criteria for bariatric and metabolic interventions within the local population in Hong Kong. The current position statement aims to provide updated guidance regarding the indications and contraindications for bariatric surgery, metabolic surgery, and bariatric endoscopic procedures.

INTRODUCTION: Seroma is a commonly encountered sequela after hernia repair. Tremendous effort has been spent to investigate the effective way to prevent this "complication" including the modification of surgical technique, use of per-peritoneal drainage, etc. There were debates about the use of monopolar diathermy versus blunt dissection in laparoscopic TEP in the prevention of seroma formation. This randomized study aims to compare the effects of using 2 techniques in laparoscopic TEP on pre-peritoneal drain output and seroma formation. METHOD: From 1.9.2018 to 30.9.2019, all male and female patients presented with the first occurrence, unilateral inguinal hernia anticipated for laparoscopic TEP were enrolled into the study after informed consent. Patients were randomized into "monopolar dissection preferred" (MDP) group and "blunt dissection-preferred" (BDP) group just before commencing of operation after general anesthesia. Surgeons were instructed to use monopolar energy as main dissection method for the whole operation if possible (MDP), whereas blunt dissection is the preferred choice in BDP group, but the use of monopolar energy was allowed if needed. Total energy time was measured by a specially designed homemade device attaching to the monopolar pedals as accurate as to millisecond (ms). Pre-peritoneal drains were inserted for drainage and removed 23 h after operation. Drainage output, total operating time, energy time, clinical and ultrasonic seroma sizes at day 1, day 6, 1-month post operations, recurrence are compared between 2 groups. RESULTS: A total of 103 patients where included. There was no significant difference in age, gender, co-morbidities, side of hernia, mean defect size, operating time, fixation adjuncts, or postoperative stay. The drain volume in BDP group is 71.13 ± 31.42 mL while it in MDP group is 56.36 ± 21.46 mL. The MDP group had significantly fewer drain output at 23 h post operation (p = 0.007) and lower seroma incidence on days 6 (p = 0.036). Overall incidence of seroma formation was 12% on postoperative day 1, 11% on postoperative day 7. No statistically differences in postoperative pain score or complications were observed at the first week, 1- and 3-months' post operation. There was no correlation with energy time to the drain output. No recurrence was found in subsequent follow-up. CONCLUSION: Pre-peritoneal drainage is clinically safe in laparoscopic totally extra-peritoneal hernioplasty and can effectively reduce the size and incidence of seroma. The seroma formation can be further reduced by appropriate use of monopolar energy as preferred dissection approach in lap TEP. Due to limitation in measuring the actual energy time, the result should be further validated by randomized multi-centers trial on its potential benefit in hernia repair by a more accurate measuring device on energy used.

Dysphagia is a common symptom of esophageal cancer (EC). Esophagectomy should relieve the presenting dysphagia as the mechanical obstruction caused by the tumor is removed. However, the new onset oropharyngeal dysphagia develops after esophagectomy and the deficit may persist increasing the risk of aspiration pneumonia and mortality as well as adversely affecting quality of life (QOL). This study investigates the persistent swallowing deficits in long-term postesophagectomy patients and explores the factors associated with dysphagia severity, penetration, and aspiration. A better understanding of the swallowing function can aid future management of the condition. A total of 29 patients who were more than six months postesophagectomy for EC, had no history of disease that would likely affect swallowing function or vocal cord palsy underwent detailed videofluoroscopic swallow studies and completed the European Organisation for Research and Treatment of Cancer QLQ-C30 and OES18 QOL questionnaires. Swallowing deficits were analyzed and rated using the videofluoroscopic dysphagia scale (VDS) and the penetration-aspiration scale (PAS). These variables were correlated with the clinical and QOL parameters to determine which factors would affect swallowing function. Our cohort consisted of 27 males and 2 females. The mean duration after esophagectomy when the swallowing study was performed was 3.2 years (range: 0.5-18.4 years). Swallowing deficits were mainly found in the pharyngeal phase of swallowing. The mean total VDS score was 36.1 (SD = 15.2, range: 11.0-69.5) out of a possible 100. The mean PAS score was 4.1 (SD = 2.5, range: 1-8) and 1.5 (SD = 0.9, range: 1-4) for thin and semisolids, respectively. Dysphagia was significantly more severe in males, those of more advanced age at esophagectomy and at swallowing assessment. Increasing pathological N stage significantly correlated with worse PAS score for thin fluid. Self-reports of more pain and less troubles with coughing were also associated with less penetration and aspiration. This study demonstrated that a mild to moderate pharyngeal dysphagia is present late after esophagectomy even in patients without VC palsy or anastomotic stricture. The long-term aspiration rate is comparable to the figures in the literature for those early after esophagectomy. It is suggested that damage to the intercostal nerves and the pulmonary vagus may affect oropharyngeal swallowing function in this population.

OBJECTIVES: Seroma is a virtually unavoidable early sequela after TEP hernioplasty. This randomised controlled trial evaluated the outcomes of preperitoneal closed-system suction drainage in laparoscopic totally extraperitoneal (TEP) hernioplasty for inguinal hernia. METHODS: Ninety patients aged 18-80 years who presented to our hospital between May 2016 and February 2017 with primary unilateral inguinal hernia were randomised into the preperitoneal drain and no-drain groups. The primary outcome was seroma size on postoperative day 6. Secondary outcomes included clinical seroma formation and seroma size on day 1, day 6, 1 and 7 months postoperatively, length of postoperative stay, pain score, and recurrence. RESULTS: There was no significant difference in age, sex, co-morbidities, hernia side, mean hernia size, operating time, fixation adjuncts, or postoperative stay. The overall incidence of clinical seroma formation was 25.6% on postoperative day 1, 60.3% on postoperative day 6, 13.2% 1 month and 0% 7 months postoperatively. The mean drain output was 57.9 ml. The drain group had significantly fewer patients with seroma on day 1 (6 vs 14, p = 0.022) and day 6 (17 vs 30, p = 0.000), and a smaller mean seroma size on days 1 and 6 (p = 0.000). Subgroup analysis showed that sac ligation versus reduction, peritoneal perforation, and fixation adjuncts had no significant effects on seroma formation or size. There is a trend of lower early post-operation VAS score and more urinary retention in drain group was observed but not reaching statistical significance. No differences in postoperative pain score or complications were observed at 1 and 7 months' post operation. CONCLUSIONS: Preperitoneal drainage for 23 h after laparoscopic TEP hernioplasty for inguinal hernia can effectively decrease seroma formation in the early postoperative period, and potentially improving postoperative pain. The benefit is short-term and no significant difference was demonstrated after 1-month post operations. This tradition technique applied to novel operative repair of inguinal hernia is safe and feasible with no significant morbidity demonstrated. Preperitoneal drainage after TEP can be considered as an option to improve patient satisfactions and recovery in selected patient group for maximal benefit, especially for those with prolonged operation which may associate with higher chance of seroma formation.

Optimal interval between neoadjuvant chemoradiotherapy (CRT) and surgery is not elucidated for esophageal squamous carcinoma. The aim of this study is to evaluate the impact of this time interval on patient outcome. Patients treated with neoadjuvant CRT followed by surgery between 2002 and 2009 were analyzed. Patients were divided into two groups based on the median interval to surgery (64 days): A = 64 days (n = 54) and B > 64 days (n = 53). A second analysis was performed by re-classifying patients into three interval groups: A* ≤ 40 days (n = 16); B* 41-80 days (n = 60); C* > 80 days (n = 31). Operative outcome, pathological data, and long-term survival were analyzed. One hundred and seven (n = 107) patients were analyzed. Five patients (9.4%) in group B had an anastomotic leak compared with no leakage from group A (P < 0.021). The complete pathological response was comparable in groups A and B (35% vs. 24.5%, p = 0.23). R0 was significantly lower in group A* (A*: 56.3%, B*: 90%, C*: 74.2%, P = 0.006). In patients with R0 resection, 5-year survival was significantly better in group A than B (71.7% vs. 51%, P = 0.032) and in group A* (A* 100% vs. B* 60.2% & C* 48.3%; A* vs. B*, P = 0.036; A* vs. C*, P = 0.019). Complete pathological response was an independent predictor of survival. Early surgery with R0 resection following neoadjuvant CRT may lead to a better outcome. Further prospective studies are still necessary to provide better insight into the issue. At present, timing of surgery should be individualized and performed at the earliest opportunity.
