Percentage of intrathoracic stomach predicts operative and post-operative morbidity, persistent reflux and PPI requirement following laparoscopic hiatus hernia repair and fundoplication.

PURPOSE: Large hiatus hernias are relatively common and can be associated with adverse symptoms and serious complications. Operative repair is indicated in this patient group for symptom management and the prevention of morbidity. This study aimed to identify predictors of poor outcomes following laparoscopic hiatus hernia repair and fundoplication (LHHRaF) to aid in counselling potential surgical candidates. METHODOLOGY: A retrospective analysis was performed from a prospectively maintained, multicentre database of patients who underwent LHHRaF between 2014 and 2020. Revision procedures were excluded. Hernia size was defined as the intraoperative percentage of intrathoracic stomach, estimated by the surgeon to the nearest 10%. Predictors of outcomes were determined using a prespecified multivariate logistic regression model. RESULTS: 625 patients underwent LHHRaF between 2014 and 2020 with 443 patients included. Median age was 65 years, 62.9% were female and 42.7% of patients had ≥ 50% intrathoracic stomach. In a multivariate regression model, intrathoracic stomach percentage was predictive of operative complications (P = 0.014, OR 1.05), post-operative complications (P = 0.026, OR 1.01) and higher comprehensive complication index score (P = 0.023, OR 1.04). At 12 months it was predictive of failure to improve symptomatic reflux (P = 0.008, OR 1.02) and persistent PPI requirement (P = 0.047, OR 1.02). Operative duration and blood loss were predicted by BMI (P = 0.004 and < 0.001), Type III/IV hernias (P = 0.045 and P = 0.005) and intrathoracic stomach percentage (P = 0.009 and P < 0.001). Post-operative length of stay was predicted by age (P < 0.001) and emergency presentation (P = 0.003). CONCLUSION: In a multivariate regression model, intrathoracic stomach percentage was predictive of operative and post-operative morbidity, PPI use, and failure to improve reflux symptoms at 12 months.

Impact of postoperative morbidity on long-term survival after oesophagectomy.

BACKGROUND: Oesophageal malignancy is a disease with a poor prognosis. Oesophagectomy is the mainstay of curative treatment but associated with substantial morbidity and mortality. Although mortality rates have improved, the incidence of perioperative morbidity remains high. This study assessed the impact of postoperative morbidity on long-term outcomes. METHODS: A prospective database was designed for patients undergoing oesophagectomy for malignancy from 1998 to 2011. An observational cohort study was performed with these data, assessing intraoperative technical complications, postoperative morbidity and effects on overall survival. RESULTS: Some 618 patients were included, with a median follow-up of 51 months for survivors. The overall complication rate was 64·6 per cent (399 of 618), with technical complications in 124 patients (20·1 per cent) and medical complications in 339 (54·9 per cent). Technical complications were associated with longer duration of surgery (308 min versus 293 min in those with no technical complications; P = 0·017), greater operative blood loss (448 versus 389 ml respectively; P = 0·035) and longer length of stay (22 versus 13 days; P < 0·001). Medical complications were associated with greater intraoperative blood loss (418 ml versus 380 ml in those with no medical complications; P = 0·013) and greater length of stay (16 versus 12 days respectively; P < 0·001). Median overall and disease-free survival were 41 and 43 months. After controlling for age, tumour stage, resection margin, length of tumour, adjuvant therapy, procedure type and co-morbidities, there was no effect of postoperative complications on disease-specific survival. CONCLUSION: Technical and medical complications following oesophagectomy were associated with greater intraoperative blood loss and a longer duration of inpatient stay, but did not predict disease-specific survival.

Gastrogastric herniation: an unusual complication following greater curve plication for the treatment of morbid obesity.

Greater curve plication is an emerging procedure for the treatment of morbid obesity. A median weight loss of up to 61% at one year has been reported in initial reports. Thus far, operative morbidity is low and there is no reported mortality. We present a case of gastric herniation after greater curve plication. Severe nausea and vomiting occurred in our patient with an excessively tight greater curve plication. Two gastric hernias developed through the plication suture. Surgical reduction of these hernias and revision of the original procedure was required. We recommend that greater curve plication is performed over a bougie and that two rows of closely spaced interrupted sutures are used to secure the plication.

Laparoscopic conversion of failed gastric banding to Roux-en-Y gastric bypass: short-term follow-up and technical considerations.

BACKGROUND: The most common bariatric procedure in Australia is laparoscopic adjustable gastric banding (LAGB). Although successful, there is a substantial long-term complication and failure rate. Band removal and conversion to Roux-en-Y gastric bypass (RYGB) can be an effective treatment for complicated or failed bands. There is increasing evidence supporting good weight loss and resolution of band-related complications after conversion. METHODS: A prospective database of all bariatric procedures is maintained. Patients having revision of LAGB to RYGB between December 2007 and April 2011 were included in this study. Indications for surgery, operative details, morbidity and mortality, weight loss data, and post-operative symptoms were recorded. RESULTS: Eighty-two patients were included. Indications for surgery were inadequate weight loss (n = 42), adverse symptoms (reflux = 8, dysphagia = 2), and band complications (band erosion = 7, band sepsis = 1, band slip = 11, esophageal dilatation = 11). Seventy-eight percent of procedures were completed in a single stage and 96.3% laparoscopically. There was no 30-day mortality. Total morbidity was 46.3% (minor complications = 32.9%, major complications = 13.4%). Median BMI was 43 kg/m(2) pre-RYGB and 34 kg/m(2) after 12 months. All patients with adverse band-related symptoms had resolution. CONCLUSIONS: LAGB has a considerable complication and failure rate. Conversion of these patients to RYGB results in further weight loss and resolution of adverse symptoms. This is a challenging procedure, but can usually be performed in a single stage with acceptable morbidity and mortality. These patients should be treated in high-volume, subspecialty bariatric units.

Management of synchronous tumours of the oesophagus and pancreatic head: a novel approach.

Synchronous tumours of the oesophagus and pancreatic head are very rare. This report describes a unique case of an adenocarcinoma of the distal oesophagus and a neuroendocrine tumour of the pancreatic head diagnosed synchronously but successfully managed metachronously. Initially, the patient underwent an oesophagectomy, with a colonic reconstruction following some months later by pylorus-preserving pancreaticoduodenectomy. A staged resection was performed after a review of the literature suggested increased morbidity with synchronous major abdominal operations.
