RESUMEN

PURPOSE: Excessive post-operative opioid prescribing has led to efforts to match prescriptions with patient need after surgery. We investigated opioid prescribing practices, rate of patient-requested opioid refills, and associated factors after laparoscopic inguinal hernia repair (LIHR). METHODS: LIHRs at a single institution from 3/2019 to 3/2021 were queried from the Abdominal Core Health Quality Collaborative for demographics, perioperative details, and patient-reported opioid usage. Opioid prescriptions at discharge and opioid refills were extracted from the medical record. Univariate and multivariable regression were used to identify factors associated with opioid refills within 30-days of surgery. RESULTS: Four hundred and ninety LIHR patients were analyzed. The median number of opioid tablets prescribed was 12 [interquartile range (IQR) 10-15], and 4% requested a refill. On univariate analysis, patients who requested refills were younger [55 years (IQR 37-61) vs. 62 years (IQR 36.8-61), p = 0.012], more likely to have undergone transabdominal preperitoneal repair (75% vs. 26.4%, p < 0.001), have a scrotal component (30% vs. 11%, p = 0.022), and have permanent tacks used (80% vs. 49.4%, p = 0.014). There was a 12% increase in the odds of opioid refill for every 1 tablet of oxycodone prescribed at discharge (95% CI for OR 1.04-1.21, p = 0.003) after controlling for age and surgery type. Patient-reported opioid use was available for 289 (59%) patients. Post-operatively, 67% of patients used ≤ 4 opioid tablets, and 87% used no more than 10 opioid tablets. CONCLUSION: Most patients use fewer opioid tablets than prescribed. Requests for opioid refills are rare following LIHR (4%) and associated with higher opioid prescribing.

RESUMEN

When achalasia is unrecognised during the preoperative phase in patients who have undergone bariatric procedures, a late Heller oesophagomyotomy may be used as the treatment modality to prevent the development of megaoesophagus. We present the case of a 66-year-old man with achalasia 3 years after a Roux-en-Y gastric bypass procedure.

RESUMEN

BACKGROUND AND AIMS: Bariatric surgery is considered the only long-lasting treatment for morbid obesity. Techniques and procedures have changed dramatically. We report on some of the major changes in the field. MATERIALS AND METHODS: We reviewed some of the major changes in trends in bariatric surgery based on some landmark paper published in the literature. RESULTS: We identified three major phases in the evolution of bariatric surgery. The pioneer phase was mostly characterized by discovery of weight loss procedures serendipitously from procedures done for other purposes. The second phase can be identified with the advent of laparoscopic techniques. This is considered the phase of greatest expansion of bariatric surgery. The metabolic phase derives from the improved understanding of the mechanisms of actions of the bariatric operations at the hormonal and molecular level. CONCLUSIONS: Bariatric surgery has changed significantly over the years. The safety of the laparoscopic approach, along with the better understanding of the metabolic changes obtained postoperatively, has led to a more individualized approach and also an attempt to expand the indications for these procedures.

RESUMEN

INTRODUCTION: Pseudocyst formation commonly follows pancreatitis, but erosion into the spleen is rare and potentially life threatening. We report a case of an intrasplenic pancreatic pseudocyst treated laparoscopically with distal pancreatectomy and splenectomy. METHODS: A 50 year old male with a history of chronic alcoholic pancreatitis, presented with abdominal pain for 3 months, worsening over the past several days. A CT scan showed a broad 9 cm subcapsular fluid collection suspicious for an intra-splenic pseudocyst. The patient underwent laparoscopic distal pancreatectomy and splenectomy. RESULTS: There were no intraoperative complications and the patient was discharged on day 8. The final pathology revealed a benign cystic lesion measuring 9 x 6 x 3 cm that was not communicating with the pancreatic duct, and 2 smaller pseudocysts in the pancreatic body and tail. A previous scan did not reveal any abnormalities in the spleen, and showed the other pancreatic pseudocysts. At 8 month follow up the patients was symptom free, with no new pseudocysts. CONCLUSIONS: Splenic parenchyma involvement is an unusual complication of pancreatic pseudocyst. The optimal treatment is controversial. Percutaneous drainage carries a high recurrence rate and risk of hemorrhage. Open surgery is effective, but associated with significant morbidity. Laparoscopy offers an effective method of treatment without the potential complication of a large abdominal incision.

RESUMEN

BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) has a high incidence of long-term complications and failures. The best procedure to handle these failures and the optimal number of stages in such cases is still controversial. The aim of this retrospective study was to compare the results of conversions of LAGB to either laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y gastric bypass (LRYGB) in failed LAGB using a single-stage approach. METHODS: All patients who underwent conversion from LAGB to either LRYGB or LSG between January 2005 and March 2012 were included in the study. Early and late complications were reviewed. The percentage excess weight loss (%EWL) between the two groups was compared at 3, 6, 12 and 24 months of follow-up. RESULTS: Fifty-nine patients, 11 men and 48 women, were included in the study. The most frequent indication was insufficient weight loss or weight regain (non-responders group), in 44 patients (75 per cent); 15 patients had a revision for complicated LAGB. The early complication rate in the non-responders group was 7 per cent (3 of 44 patients), compared with 13 per cent (2 of 15) in the complicated LAGB group. Mean(s.d.) %EWL in the non-responders group was 55(22) per cent in patients converted to LRYGB and 28(25) in those converted to LSG (P = 0·001). CONCLUSION: LRYGB and LSG are both safe and feasible options for failed or complicated LAGB. In the non-responders group, %EWL was superior for conversion to LRYGB. The surgical morbidity rate was highest in patients having revision for band complications.

RESUMEN

BACKGROUND: Single-stage laparoscopic sleeve gastrectomy (LSG) may represent an additional surgical option for morbid obesity. METHODS: We performed a retrospective review of a prospectively maintained database of LSG performed from November 2004 to April 2007 as a one-stage primary restrictive procedure. RESULTS: One hundred forty-eight LSGs were performed as primary procedures for weight loss. The mean patient age was 42 years (range, 13-79), mean body mass index of 43.4 kg/m(2) (range, 35-75), mean operative time of 60 min (range, 58-190), and mean blood loss of 60 ml (range, 0-300). One hundred forty-seven procedures (99.3%) were completed laparoscopically, with a mean hospital stay of 2.7 days (range, 2-25). A 2.7% major complication rate was observed with four events in three patients and no deaths. Four patients required readmission; mild dehydration in two, choledocholithiasis in one, and a gastric sleeve stricture in one. CONCLUSION: Laparoscopic SG is a safe one-stage restrictive technique as a primary procedure for weight loss in the morbidly obese with an acceptable operative time, intraoperative blood loss, and perioperative complication rate.

RESUMEN

BACKGROUND: Morbid obesity is associated with a high prevalence of cholecystopathy, and there is an increased risk of cholelithiasis during rapid weight loss following gastric bypass. In the era of open gastric bypass prophylactic cholecystectomy was advocated. However, routine cholecystectomy at laparoscopic gastric bypass is controversial. METHODS: We performed a retrospective review of a prospectively maintained database of morbidly obese patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) from February 2000 to August 2006. All had routine preoperative biliary ultrasonography. Concomitant cholecystectomy at LRYGB was planned in patients with proven cholelithiasis and/or gallbladder polyp > or = 1 cm diameter. RESULTS: 1711 LRYGBs were performed. Forty-two patients (2.5%) had a previous cholecystectomy and were excluded from further analysis. Two hundred and five patients (12%) had gallbladder pathology: cholelithiasis in 190 (93%), sludge in 14 (6.8%), and a 2 cm polyp in 1 (0.5%). One hundred and twenty-three patients with cholelithiasis (65%) had a concomitant cholecystectomy at LRYGB, while 68 (35.7%) did not. Of these, 123 (99%) were completed laparoscopically. Concomitant cholecystectomy added a mean operative time of 18 min (range 15-23 min). One patient developed an accessory biliary radicle leak requiring diagnostic laparoscopic transgastric endoscopic retrograde cholangiopancreatography (LTG-ERCP). Of the 68 patients with cholelithiasis who did not undergo cholecystectomy 12 (17.6%) required subsequent cholecystectomy. A further 4 patients with preoperative gallbladder sludge required cholecystectomy. All procedures were completed laparoscopically. One patient required laparoscopic choledochotomy and common bile duct exploration (CBDE) with stone retrieval. Eighty-eight patients (6%) with absence of preoperative gallbladder pathology developed symptomatic cholelithiasis after LRYGB; 69 (78.4%) underwent laparoscopic cholecystectomy; 3 presented with gallstone pancreatitis and 2 with obstructive jaundice, requiring laparoscopic transcystic CBDE in 4 and LTG-ERCP in one. CONCLUSION: In our experience, concomitant cholecystectomy at LRYGB for ultrasonography-confirmed gallbladder pathology is feasible and safe. It reduces the potential for future gallbladder-related morbidity, and the need for further surgery.

RESUMEN

BACKGROUND: Gastro-gastric fistula (GGF) formation is uncommon after divided laparoscopic Roux-en-Y gastric bypass (LRYGB) for morbid obesity. Optimal surgical management remains controversial. METHODS: A retrospective review was performed of a prospectively maintained database of patients undergoing LRYGB from January 2001 to October 2006. RESULTS: Of 1,763 primary procedures, 27 patients (1.5%) developed a GGF and 10 (37%) resolved with medical management, whereas 17 (63%) required surgical intervention. An additional seven patients requiring surgical intervention for GGF after RYGB were referred from another institution. Indications for surgery included weight regain, recurrent, or non-healing gastrojejunal anastomotic (GJA) ulceration with persistent abdominal pain and/or hemorrhage, and/or recurrent GJA stricture. Remnant gastrectomy with GGF excision or exclusion was performed in 23 patients (96%) with an average in-hospital stay of 7.5 days (range, 3-27). Morbidity in six patients (25%) was caused by pneumonia, n=2; wound infection, n=2; staple-line bleed, n=1; and subcapsular splenic hematoma, n=1. There were no mortalities. Complete resolution of symptoms and associated ulceration was seen in the majority of patients. CONCLUSION: Although uncommon, GGF formation can complicate divided LRYGB. Laparoscopic remnant gastrectomy with fistula excision or exclusion can be used to effectively manage symptomatic patients who fail to respond to conservative measures.

RESUMEN

BACKGROUND: Most studies investigating esophageal motility among the morbidly obese have focused on the relationship between lower esophageal sphincter (LES) pressure and gastroesophageal reflux disease (GERD). Very few studies in the literature have examined motility disorders among the morbidly obese population in general outside the context of GERD. This study aimed to determine the prevalence of esophageal motility disorders in obese patients selected for bariatric surgery. METHODS: A total of 116 obese patients (81 women and 35 men) selected for laparoscopic gastric banding underwent manometric evaluation of their esophagus from January to March 2003. Tracings were retrospectively reviewed for the end points of LES resting pressure, LES relaxation, and esophageal peristalsis. RESULTS: The study patients had a body mass index (BMI) of 42.9 kg/m2, and a mean age of 48.6 years. The following abnormal manometric findings were demonstrated in 41% of the patients: nonspecific esophageal motility disorders (23%), nutcracker esophagus (peristaltic amplitude >180 mmHg) (11%), isolated hypertensive LES pressure (>35 mmHg) (3%), isolated hypotensive LES pressure (<12 mmHg) (3%), diffuse esophageal spasm (1%), and achalasia (1%). Only one patient with abnormal esophageal motility reported noncardiac chest pain. CONCLUSIONS: Despite a high prevalence of esophageal dysmotility in our morbidly obese study population, there was a conspicuous absence of symptoms. Although the patients in this study were not directly questioned with regard to esophageal symptoms, several studies in the literature support our conclusion.

RESUMEN

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (RYGBP) has been used increasingly more often in the past 10 years. The authors summarize their experience and safety/complications data based on 849 laparoscopic RYGBP procedures. They also evaluate the use of the Endopath trocar in terms of trocar-site hernias, bowel obstruction, and elimination of time-consuming fascial closure. METHODS: From July 2000 to December 2003, 849 laparoscopic RYGBP procedures were performed using a bladeless, 12-mm, visual entry trocar. The patients' average body mass index (BMI) was 53.2 kg/m2. The trocar ports (n = 3,744) were not closed. Perioperative and postoperative assessments were performed. RESULTS: In this study, 74% of the patients were retained for follow-up evaluation (mean, 10 months). Among these patients, no intraoperative bowel or vascular injuries, no mortality, and two trocar-site hernias (0.2%) were found. At 1 year, the mean excess weight loss was 73.4%. CONCLUSIONS: The Endopath trocar system shows a trend toward reducing trocar-site hernias, decreasing bowel obstruction, and eliminating the need for time-consuming fascial closure, although further studies are needed to confirm these findings.

RESUMEN

BACKGROUND AND STUDY AIMS: Increased intra-abdominal pressure has been associated with increased intracranial pressure. Bowel insufflation during colonoscopy may increase the intra-abdominal pressure. It was hypothesized that colonoscopy may be associated with intracranial pressure elevation subsequent to an elevation in intra-abdominal pressure. MATERIALS AND METHODS: Colonoscopy was carried out in seven anesthetized pigs, and the colonoscope was advanced up to 60 cm from the anal verge. Insufflation was used to allow safe advancement of the colonoscope and to allow visualization of the colon, in the same way as in the procedure performed in humans. Intra-abdominal pressure was measured by determining the hydrostatic pressure in the urinary bladder. A subarachnoid screw was used to monitor intracranial pressure. The mean arterial blood pressure and intra-abdominal venous pressure were directly monitored via the femoral vessel access; all parameters were recorded before and during colonoscopy. RESULTS: A statistically significant elevation in intracranial pressure was demonstrated during colonoscopy. The average increase in intracranial pressure was 3.1 mm Hg. The intra-abdominal pressure and intra-abdominal venous pressure were also significantly elevated during the procedure. CONCLUSIONS: Colonoscopy may increase intracranial pressure due to an increase in intra-abdominal pressure. This may have clinical implications when colonoscopy is conducted in patients with brain pathology associated with high intracranial pressure.

RESUMEN

BACKGROUND: The purpose of this study was to determine the use of different laparoscopic approaches in the management of gastric neoplasms based on tumor type and location. METHODS: We retrospectively reviewed the records of seven patients (3 men and 4 women) with 11 gastric lesions who were referred to our facility between March 2000 and October 2001 for laparoscopic excision of gastric neoplasms. RESULTS: Two patients had gastrointestinal stromal lesions (3 lesions); two patients had hyperplastic polyps (3 lesions); one patient had carcinoid tumor (2 lesions); one patient had a carcinoma in situ and an adenoma; and one patient had an ectopic pancreas. Extraluminal laparoscopic wedge resection was used in four patients with lesions at the anterior gastric wall or along the lesser or greater curvature. Intragastric excision was used in two patients with small posterior wall lesions, and a transgastrotomy approach was used in one patient with a posterior wall lesion that could not be removed by the intragastric approach. All the lesions were completely excised with clear margins. The median hospital stay was 3 days. Complications developed in two patients. One patient presented with a perforated ulcer 2 weeks after surgery, and a second patient had postoperative pyloric edema that resolved with conservative treatment. CONCLUSIONS: The use of different laparoscopic approaches based on gastric neoplasm type and location facilitates tumor access and resection.

RESUMEN

BACKGROUND: Failure of arterial serum lactate to achieve normal levels has been associated with an increased mortality among medical and trauma patients. At our institution the ability of the patient to normalize arterial serum lactate has been utilized as an end point of resuscitation. In this study, we examine the correlation between length of time to lactate normalization and mortality. METHODS: The charts of 95 consecutive surgical intensive care unit (SICU) patients requiring hemodynamic monitoring or therapy were reviewed retrospectively. Hemodynamic, demographic, and laboratory data were recorded. Patients were stratified by lactate normalization time, and a subgroup analysis of survivors and nonsurvivors was performed by univariate and multivariate analysis. RESULTS: Patients not achieving a normal lactate level sustained a 100% hospital mortality rate. Those clearing between 48 and 96 hours sustained a 42.5% mortality rate. Patients normalizing in 24 to 48 hours had a 13.3% mortality rate, and those clearing in less than 24 hours had a mortality rate of 3.9%. Subgroup analysis by survival revealed differences in time to lactate clearance, initial blood pressure, and initial lactate on univariate analysis. On multivariate analysis only time of lactate clearance was found to differ. CONCLUSIONS: Prolongation of lactate clearance is associated with increasing mortality. Failure of a patient to normalize lactate is associated with 100% mortality. Measurement of arterial serum lactate is a simple and effective predictor of outcome and end point of therapy.
