Total extraperitoneal laparoscopic inguinal hernia repair with adductor tenotomy: a 10-year experience in the treatment of athletic pubalgia.

BACKGROUND: Athletic pubalgia, commonly referred to as a "sports hernia," is a disease process characterized by groin pain produced by physical exertion often occurring in patients whose athletic activities require them to make rapid changes in direction. The groin pain is due to the traction-countertraction relationship between the adductor muscles and the weaker abdominal muscles. Hence, a few studies have shown inguinal hernia repair with adductor tenotomy to be an effective treatment for this pathology (Brody in Hernia 21:139-147, 2016, https://doi.org/10.1007/s10029-016-1520-8 ; Rossidis et al. in Surg Endosc 29:381-386, 2015, https://doi.org/10.1007/s00464-0143679-3 ). However, these studies are small and few in quantity but have demonstrated promising results. Thus, we sought to further study this combined surgical approach as a treatment for this multifactorial disease to improve our understanding and outcomes. METHODS: With IRB approval, we retrospectively reviewed the charts of all patients who underwent adductor tenotomy and inguinal hernia repair for the treatment of athletic pubalgia at Mount Sinai Medical Center, Miami Beach FL. Parameters gathered included basic demographics, past medical and surgical history, athletic activity, length of surgery, length of time between surgery and follow-up, intraoperative and postoperative complications, and time to return to athletic activities. RESULTS: A total of 93 patients underwent inguinal hernia repair with adductor tenotomy. These procedures were all performed by a single surgeon at two academic institutions. The average age of patients was 23.4 years. Athletic activities reported by the patients were as follows: American football (n = 36), soccer (n = 18), triathlon (n = 11), track and field (n = 8), and baseball (n = 5). Less-represented activities included swimming (n = 3), tennis (n = 2), lacrosse (n = 1), golf (n = 1), and other (n = 8). Mean operative time was 72.4 min. Most patients were found to return to athletic activity in 28 days following a standardized physical therapy regimen (92.5%). Postoperative complications included recurrence of pain/symptoms (7.5%, n = 7), urinary retention (2.2%, n = 2), pain along the adductor magnus/brevis muscle group with more extraneous activity (1.1%,  n = 1), and adductor brevis hematoma 3 months following surgery and rehabilitation (1.1%, n = 1). Of the patients with recurrent pain, 2/7 reported contralateral pain. CONCLUSIONS: Total extraperitoneal laparoscopic inguinal hernia repair with adductor tenotomy appears to be a relatively quick and safe procedure with few postoperative complications. The majority of treated athletes are able to return to full athletic activities within 28 days of operation. While a return of symptoms has been seen in some patients, it is frequently observed on the contralateral side.

Laparoscopic proximal gastrectomy for gastric neoplasms.

BACKGROUND: For cancers of the distal gastroesophageal junction or the proximal stomach, proximal gastrectomy can be performed. It is associated with several perioperative benefits compared with total gastrectomy. The use of laparoscopic proximal gastrectomy (LPG) has become an increasingly popular approach for select tumors. METHODS: We describe our method of LPG, including the preoperative work-up, illustrated depictions of the key steps of the surgery, and our postoperative pathway. RESULTS: A total of 6 patients underwent LPG between July, 2013 to June, 2017. Five patients had early-stage adenocarcinoma, and 1 patient had a gastrointestinal stromal tumor. The median age of the cohort was 70, and each patient had significant comorbidities. Conversion to open was required for 1 patient. All patients had negative final margins and an adequate lymph node dissection (median number of nodes examined was 15, range 12-22). The median postoperative length of stay was 7 days (range 4-7). Two patients developed anastomotic strictures requiring intervention, and 1 patient experienced significant reflux. At a median follow-up of 11 months, there was 1 recurrence. Three patients were alive without evidence of disease, and 2 patients died from other causes. CONCLUSIONS: For carefully selected patients, LPG is a safe and reasonable alternative to total gastrectomy, which is associated with similar oncologic outcomes and low morbidity.

Minimally Invasive Esophagectomy Utilizing a Stapled Side-to-Side Anastomosis is Safe in the Western Patient Population.

BACKGROUND: There has been an increased utilization of minimally invasive esophagectomy (MIE) in an effort to reduce morbidity, decrease length of stay, and improve quality of life. However, there are limited large series of patients undergoing MIE from the United States and no standardized approach. We reviewed our experience with MIE utilizing a stapled side-to-side anastomosis during a 7.5-year period. STUDY DESIGN: A retrospective review of prospectively maintained databases for patients undergoing planned esophagectomy were reviewed from 2007 to 2015. Esophagogastric anastomoses were performed via a 6-cm linear stapled side-to-side method. Demographics, comorbidities, surgical approach, pathology data, and postoperative morbidities were recorded and reviewed. RESULTS: A MIE was attempted in 303 of 315 (96 %) patients, and a total minimally invasive approach was completed in 293 of 315 (93 %) patients. Location of anastomosis was predominantly in the neck, with 244 patients (77.5 %) undergoing a total minimally invasive McKeown approach (n = 231). A total, minimally invasive Ivor-Lewis was completed in 60 patients (19.1 %). Anastomotic leak was identified in 24 patients (7.6 %). Rates of anastomotic leak were 4.4 % for Ivor-Lewis and 8.5 % for McKeown resection. Median length of stay was 8 days, and in-hospital mortality occurred in only three patients (n = 1 %). Ninety-day follow-up demonstrated a 4.1 % stricture rate requiring dilatation. CONCLUSIONS: In the Western patient population, MIE utilizing a 6-cm stapled side-to-side anastomosis is associated with low rates of anastomotic leak, stricture, and mortality.

Total laparoscopic resection for advanced gastric cancer is safe and feasible in the Western population.

BACKGROUND: There is debate surrounding the use of laparoscopic resection for advanced gastric cancer in the Western population. Here we aim to assess the feasibility and short-term outcomes of laparoscopic gastrectomy in consecutive patients in a Western population. METHODS: From 2012 to 2014, retrospective review of 28 patients with clinically staged advanced gastric cancer (≥T3 or ≥N1) treated with laparoscopic resection. RESULTS: Sixty-one percentage of patients were male. Median age was 67 years (range 35-86). Median BMI was 26.5 (range 19.4-46.1). Resection types were proximal (n = 2), distal (n = 14), and total (n = 12). Twenty-six (93 %) patients underwent D2 lymphadenectomy. Four patients underwent conversion to open. Median blood loss was 125 mL (range 30-300). Median LOS was 7 days (range 4-16). Of postoperative complications, five were minor: arrhythmia (n = 1), surgical site infection (n = 3), in-hospital fall (n = 1); and four were major (intra-abdominal abscess, stricture, PE, and anastomotic bleed). T stages were Tx (n = 1), T2 (n = 3), T3 (n = 18), and T4 (n = 6). N stages were N0 (n = 4), N1 (n = 8), N2 (n = 1), and N3 (n = 15). Median tumor size was 5.8 cm (range 0-9.5). Median lymph node yield was 22 (range 6-53). All margins were negative. Median follow-up was 12.8 months (range 2-27). Six patients have died of progressive disease. CONCLUSION: Following total laparoscopic resection for advanced gastric cancer, oncologic endpoints, postoperative course, and early cancer-specific follow-up are excellent. The results demonstrated here support the routine use of these techniques in the Western patient population.

Design and experimental evaluation of an anti-leak feeding tube.

BACKGROUND: Enteral feeding via gastrostomy or jejunostomy tube is often required to adequately treat patients with cancer, gastrointestinal disorders, and cerebral vascular accident. Although sufficient to provide adequate caloric intake, the present design of a gastrostomy tube is inadequate. Leakage of gastric contents onto the skin is commonplace prompting emergency department visits and skin damage that requires costly nonoperative and operative intervention. We introduce a new gastrostomy tube design and prototype that inhibits leakage by using an adjustable external retaining member, which compresses against the feeding tube shaft thereby preventing dynamic friction. METHODS: A conventional external retaining member of a 22 French gastrostomy tube was tested against a novel compression-fitting external retaining member. Each gastrostomy tube was clamped to a scale and the external retaining member moved to slide along the tubing at a constant rate, and the applied frictional force was recorded. Thirty repetitions were performed. RESULTS: The experimental prototype generated ×2.5-3 the frictional force preventing tube excursion. Mean (standard deviation) forces were 18 (3) versus 46 (4) ounces (n = 10, P = 2.57E-13) and 15 (4) versus 48 (4) ounces (n = 10, P = 1.90E-13) for conventional and experimental designs, respectively. Simulated in situ environment mean forces were 19 (3) versus 39 (3) ounces (n = 10, P = 3.30E-11) for conventional and experimental designs, respectively. CONCLUSIONS: The experimental design created an increased static frictional force that inhibited the movement of the external retaining member against the gastrostomy tube. Clinical implementation is the next step to evaluate for reduced feeding tube morbidity and healthcare expenses by preventing leakage of gastric contents.

Laparoscopic hernia repair with adductor tenotomy for athletic pubalgia: an established procedure for an obscure entity.

INTRODUCTION: Athletic pubalgia is a syndrome of chronic lower abdomen and groin pain that occurs in athletes. It is the direct result of stress and microtears of the rectus abdominis inserting on the pubis from the antagonizing adductor longus muscles, and weakness of the posterior transversalis fascia and bulging of the inguinal floor. METHODS: Under IRB approval, we conducted a retrospective review of our prospectively competitive athlete patients with athletic pubalgia from 2007 to 2013. RESULTS: A cohort of 54 patients was examined. Mean age was 22.4 years. Most patients were football players (n = 23), triathlon (n = 11), track and field (n = 6), soccer players (n = 5), baseball players (n = 4), swimmers (n = 3), golfer (n = 1), and tennis player (n = 1). Fifty one were males and three were females. All patients failed medical therapy with physiotherapy prior to surgery. 76 % of patients had an MRI performed with 26 % having a right rectus abdominis stripping injury with concomitant strain at the adductor longus musculotendinous junction. 7 % of patients had mild nonspecific edema in the distal bilateral rectus abdominis muscles without evidence of a tear. Twenty patients had no findings on their preoperative MRI, and only one patient was noted to have an inguinal hernia on MRI. All patients underwent laparoscopic totally extraperitoneal inguinal hernia repair with synthetic mesh and ipsilateral adductor longus tenotomy. All patients were able to return to full sports-related activity in 24 days (range 21-28 days). One patient experienced urinary retention and another sustained an adductor brevis hematoma 3 months after completion of rehabilitation and surgical intervention. Mean follow up was 18 months. CONCLUSION: Athletic pubalgia is a disease with a multifactorial etiology that can be treated surgically by a laparoscopic totally extraperitoneal hernia repair with synthetic mesh accompanied with an ipsilateral adductor longus tenotomy allowing patients to return to sports-related activity early with minimal complications.

Tracking Cancer: Exploring Heart Rate Variability Patterns by Cancer Location and Progression.

Reduced heart rate variability (HRV) is an autonomic nervous system (ANS) response that may indicate dysfunction in the human body. Consistent evidence shows cancer patients elicit lower HRV; however, only select cancer locations were previously evaluated. Thus, the aim of the current study was to explore HRV patterns in patients diagnosed with and in varying stages of the most prevalent cancers. At a single tertiary academic medical center, 798 patients were recruited. HRV was measured via an armband monitor (Warfighter MonitorTM, Tiger Tech Solutions, Inc., Miami, FL, USA) equipped with electrocardiographic capabilities and was recorded for 5 to 7 min with patients seated in an upright position. Three time-domain metrics were calculated: SDNN (standard deviation of the NN interval), rMSSD (the root mean square of successive differences of NN intervals), and the percentage of time in which the change in successive NN intervals exceeds 50ms within a measurement (pNN50). Of the 798 patients, 399 were diagnosed with cancer. Cancer diagnoses were obtained via medical records one week following the measurement. Analysis of variance models were performed comparing the HRV patterns between different cancers, cancer stages (I-IV), and demographic strata. A total of 85% of the cancer patients had breast, gastrointestinal, genitourinary, or respiratory cancer. The cancer patients were compared to a control non-cancer patient population with similar patient size and distributions for sex, age, body mass index, and co-morbidities. For all HRV metrics, non-cancer patients exhibited significantly higher rMSSDs (11.1 to 13.9 ms, p < 0.0001), SDNNs (22.8 to 27.7 ms, p < 0.0001), and pNN50s (6.2 to 8.1%, p < 0.0001) compared to stage I or II cancer patients. This significant trend was consistently observed across each cancer location. Similarly, compared to patients with stage III or IV cancer, non-cancer patients possessed lower HRs (-11.8 to -14.0 bpm, p < 0.0001) and higher rMSSDs (+31.7 to +32.8 ms, p < 0.0001), SDNNs (+45.2 to +45.8 ms), p < 0.0001, and pNN50s (19.2 to 21.6%, p < 0.0001). The HR and HRV patterns observed did not significantly differ between cancer locations (p = 0.96 to 1.00). The depressed HRVs observed uniformly across the most prevalent cancer locations and stages appeared to occur independent of patients' co-morbidities. This finding highlights the potentially effective use of HRV as a non-invasive tool for determining common cancer locations and their respective stages. More studies are needed to delineate the HRV patterns across different ages, between sexes and race/ethnic groups.

Decreasing morbidity and mortality in 100 consecutive minimally invasive esophagectomies.

INTRODUCTION: Esophagectomy is a complex invasive procedure that requires exploration of multiple body cavities for removal and subsequent restoration of gastrointestinal continuity. In many institutions, esophagectomy morbidity and mortality rates remain high despite improvement of intensive care treatment. We reviewed our minimally invasive esophagectomy (MIE) experience of a consecutive series of 100 patients to analyze trends in morbidity and mortality as we transitioned from open to MIE. METHODS: A total of 105 consecutive patients who underwent operative exploration for esophagectomy from August 2007 to January 2011 were reviewed. The preoperative evaluation, operative technique, and postoperative care of these cases were evaluated and analyzed for 100 patients who have had a MIE and compared with 32 open esophagectomies 2 years prior. RESULTS: During the time frame of the study, 105 patients underwent an exploration for attempted esophagectomy. Resection was completed in 100 patients and was done for malignant disease in 95 patients and benign disease in 5 patients. There was one in hospital mortality due to a pulmonary embolism. There was no significant difference in postoperative complications consisting of transient left recurrent nerve injury (7 vs. 12.5%) or pneumonia (9 vs. 15.6%) in those who underwent MIE compared with open resection. However, wound infections were significantly less in patients who underwent MIE compared with open esophagectomy (1 vs. 12.5%, respectively, p = 0.01). Anastomotic leak (4 vs. 12.5%, p = 0.05) also was lower in those who underwent MIE. Median length of stay (LOS) was significantly less in patients who underwent MIE compared with open esophagectomy (7.5 vs. 14 days, p < 0.05). Finally, there was a trend toward improvement in median LOS in the 30 patients who underwent MIE during the most recent time period compared with the initial 17 patients who underwent MIE (7.5 vs. 10 days, p = 0.05) CONCLUSIONS: Our results support the continued safe use of esophagectomy for selected esophageal diseases, including malignancy. Morbidity, especially wound infection, anastomotic leak, and length of stay is decreasing with the incorporation of minimally invasive techniques.

Routine Radiologic Assessment for Anastomotic Leak Is Not Necessary in Asymptomatic Patients After Esophagectomy for Esophageal Cancer.

BACKGROUND: Anastomotic leaks (AL) are a major source of post-esophagectomy morbidity and patients are often initially asymptomatic. Debate exists on timing and utility of imaging to detect AL post-esophagectomy. We sought to evaluate the efficacy and timing of radiographic AL evaluation in esophageal cancer patients post-esophagectomy. METHODS: A retrospective database of esophageal cancer patients who underwent esophagectomy at a single institution from 2004 to 2020 was used to determine the utilization, timing, and sensitivity of radiologic testing for AL post-esophagectomy. RESULTS: Seventy-six patients were identified of which 37 (49%) had a cervical anastomosis. Sixty-four (84%) underwent 71 "asymptomatic radiographic leak tests" (ARLT), 7 of which had 2 different tests, including: 41 fluoroscopic esophagrams (58%), 18 CT-esophagrams (25%), and 12 upper GI studies (17%). Seventeen patients (22%) developed clinical signs of AL (hemodynamic instability, leukocytosis) and underwent "symptomatic radiographic leak tests" (SRLT) with fluoroscopic esophagram (n = 9, 12%), CT-esophagram (n = 7, 9%), or upper GI study (n = 1, 1%). ARLT and SRLT were positive in 2/64 (3%) and 17/17 (100%) patients, respectively, for 19 total ALs (25%). Among the 17 SRLT( +) patients, 1 was also ARLT( +), 13 were initially ARLT( -), and 3 were not evaluated by ARLT. The median postoperative day for ARLT and SRLT was 4.0 (IQR 3.0-5.5) and 9.0 days (IQR 6.0-13.0), respectively, with a statistically significant difference (p < 0.005). The sensitivity and specificity of ARLT for detecting AL were 13.3% and 100.0%, respectively. CONCLUSIONS: Based on the low ARLT sensitivity, routine use of imaging to detect asymptomatic ALs post-esophagectomy may be limited. Symptomatic ALs were often present in a delayed fashion, even after initial negative imaging.

Squamous cell carcinoma arising in a Zenker diverticulum.

Squamous cell carcinoma (SCC) arising in a Zenker diverticulum (ZD) is an extremely rare entity. Approximately 50 cases have been reported worldwide. We report a case of a 74-year-old man who presented to our institution with chronic regurgitation, dysphagia and halitosis. The patient was initially seen in 2015 at which point he reported a 10-year history of these symptoms and was diagnosed with ZD. A barium swallow was done revealing a large posterior esophageal diverticulum with significant residual contrast within the diverticulum lumen. Given these findings, he was taken for open surgical excision where a SCC was identified. Although it is extremely rare for a SCC to occur in a ZD, patients with ZD must undergo regular surveillance endoscopy of the esophagus and the diverticulum itself to identify any suspicious mass or lesion arising in within.

Heterotopic mesenteric ossification: a report of two cases.

Heterotopic mesenteric ossification (HMO) is abnormal bone formation in tissues which usually do not undergo ossification. There are approximately 75 cases reported worldwide. We present two cases of HMO. The first case is that of a 39-year-old man who presented with abdominal pain and a computerized tomography scan of the abdomen and pelvis revealed an apple core lesion resulting in small bowel obstruction. The second case is that of a 36-year-old woman who presented 2 months after undergoing robotic gastric sleeve resection complaining of weakness and emesis. An esophagogram revealed kinking at the distal esophagus. Surgical resection was performed in both, yielding the diagnosis of HMO. There are various theories as to the pathophysiology of HMO, but no clearly defined mechanism has been established. Management should be conservative whenever possible to prevent further ossification with subsequent surgical intervention.

Algorithm for the management of endoscopic perforations: a quality improvement project.

Perforations are an uncommon but serious complication of endoscopy. Although they are well recognized, no universally accepted strategy for their management exists. The need for management algorithms in situations that call for multiple interventions in a short time, with coordinated effort encompassing multiple providers from different specialties, has long been recognized, but no such clinical care pathway has been developed for the management of endoscopic perforations. Since perforations are uncommon, a predetermined plan of action can streamline patient management. Furthermore, such a plan demonstrates preparedness on the part of the gastroenterologist. We developed an endoscopic perforation management strategy based on the best available scientific evidence and our specific resources. We report our experience in the hope that it may form a useful framework for gastroenterologists attempting to do the same at their own institution.

Minimally invasive esophagectomy is safe and effective following neoadjuvant chemoradiation therapy.

BACKGROUND: Minimally invasive esophagectomy (MIE) is technically demanding, and implementation has been hindered by a steep learning curve. Despite widespread concern about the successful performance of this procedure following neoadjuvant chemoradiotherapy (NACR) treatment, we hypothesized that safe and effective MIE could be performed in this setting. MATERIALS AND METHODS: We reviewed our prospective database of patients undergoing MIE for esophageal cancer at our institution between January 2008 and February 2010. We analyzed the association of NACR on perioperative outcomes and compared them with those patients undergoing MIE without NACR. NACR was used in ≥T2 or N+ tumors. RESULTS: A total of 61 consecutive patients underwent a planned MIE. A complete MIE or hybrid procedure was performed in 58 patients (95%), while 3 patients were unresectable. Median age was 67 years (range 38-85). Anastomoses were performed in the cervical region in 47 patients (81%) while 11 patients had an anastomosis in the right chest. Serious complications included: 3 cervical anastomotic leaks (5%), 2 thoracic duct leaks (4%), 12 pneumonias (21%), 10 atrial fibrillations (18%), and 1 death in a patient not undergoing NACR. NACR was used in 41 patients. There was no significant difference in estimated blood loss (EBL), complications, or negative pathologic margins in patients undergoing NACR with MIE vs. MIE alone (P=NS). Median number of lymph nodes excised and PostOp LOS was 15 and 11 in patients undergoing NACR compared with 13 and 9 in those undergoing MIE alone (P=NS). CONCLUSION: MIE is safe following NACR. Excellent results can be achieved with this operation in patients with advanced tumors.

Esophageal cancer--the five year survivors.

BACKGROUND: Esophageal cancer in the United States carries a poor prognosis with overall 5 year survival rate of approximately 10%. Due to this dismal outcome, data analyzing factors predictive of survival for greater than 5 years are not available. METHODS: Single institution retrospective review of esophageal resection for curative intent from 1984 to 2004. We identified 50 actual 5 year survivors (long term survivors, LTS) out of 266 patients (19%) with invasive esophageal cancer and, using multivariate logistic regression, compared characteristics between the LTS, and short-term (<5 year) survivors (STS). RESULTS: There was no significant difference in clinical T stage or N stage by EUS (P = 0.81) or in the utilization of neoadjuvant therapy in the LTS versus STS (58% vs. 62%, respectively, P = 0.36). The LTS group was significantly more likely to have pathologic complete response (69% vs. 41%, P < 0.001), lower pathologic T stage, i.e., pT0, pTis, or pT1 (83% vs. 45%, P < 0.001), pN0 stage (97% vs. 68%, P < 0.001), favorable tumor differentiation (well or well to moderate, 39% vs. 13%, P < 0.001), and absence of angiolymphatic (88% vs. 69%, P < 0.01) or perineural invasion (95% vs. 83%, P = 0.04). In comparing the factors predictive of outcome in LTS versus the STS with increasing relative risk, absence of perineural invasion (RR 0.41 (0.27, 0.61)), negative margins (RR 0.41 (0.29, 0.57)), absence of angiolymphatic invasion (RR 0.39 (0.30, 0.51)), pN0 stage (RR 1.37 (1.23, 1.52)), pT0 or pT1 (RR 1.85 (1.64, 2.07)), pathologic complete response (RR 2.02 (1.76, 2.31)), and favorable tumor grade (RR 3.00 (2.49, 3.61)) were associated with improved survival. CONCLUSION: Tumor biological factors including favorable tumor grade may be the most important influence on 5 year actual survival in esophageal cancer.

Robotic LINX Placement: Is it Worth It?

Background: Laparoscopic Nissen fundoplication is considered the current gold standard of surgical treatment of gastroesophageal reflux disease. Magnetic sphincter augmentation with the LINX® device was developed as a less technically challenging alternative that has proven to be a safe and effective surgical antireflux procedure. Despite rapid adoption of the robotic platform in many areas of general surgery, no studies have compared laparoscopic and robotic approaches to placement of the LINX device. This retrospective study is the first to compare the robotic platform with the laparoscopic approach for minimally invasive LINX placement. Methods: We conducted a retrospective review of a total cohort of 20 patients who underwent LINX placement with hiatal hernia repair at our institution. Half of the patients underwent surgery using laparoscopy and the other half with robotic technology. Patient characteristics, surgical outcomes, and charge differences were analyzed. Results: We found that there were no significant differences in hospital length of stay, surgical outcomes, use of proton pump inhibitors (PPIs) postoperatively, or postoperative dysphagia. Patients undergoing robotic surgery had longer operative time (139 ± 25 minutes versus 81 ± 14 minutes, P < .01), higher intraoperative charges ($8980 ± 275 versus $7239 ± 355, P < .01), and higher charges associated with their hospital stay ($45,037 ± 4112.41 versus $39,565 ± 3731.64, P < .01). Conclusions: In comparison with laparoscopic LINX procedures, robotic LINX does not offer superior surgical outcomes in terms of postoperative PPI use, dysphagia, or hospital length of stay. Robotic LINX procedures are associated with increased operative time and overall charges.

A Retrospective Analysis of the Trends in Acute Appendicitis During the COVID-19 Pandemic.

Background: The corona virus disease of 2019 (COVID-19) imposed new public health constraints that deterred people from coming to the hospital. The outcome of patients who developed appendicitis during mandated COVID-19 quarantine has yet to be examined. The main objective was to establish whether there was an increased rate of perforated appendicitis seen during COVID-19 quarantine. Secondary objectives included observing the type of procedure performed, length of stay, and associated complications. Materials and Methods: This retrospective analysis was designed to look at the rates of appendicitis and perforated appendicitis observed during mandatory "safer at home order" from March to May 2020. The same time period a year earlier was used for comparative analysis. The study utilized data gathered from a single health care system, which consisted of a large regional referral center with three emergency rooms (ERs). Patients were included in the study if they presented to any ER in our health care system with a chief complaint of acute appendicitis. Perforated appendicitis was determined either radiographically or intraoperatively. Interventions included surgery, percutaneous drainage, or medical management. Results: There were 107 patients who were included. During quarantine, a total of 48 patients presented with acute appendicitis, with 16 perforations, compared with the previous year where 59 patients presented with acute appendicitis, with 10 perforations (33% versus 17% P = .04). Most patients underwent laparoscopic appendectomy (91%, n = 98), six patients (6%) were managed with intravenous antibiotics and 3 patients (3%) with percutaneous drainage. Patients who perforated had a longer duration of symptoms (2 versus 1, P = .03), white blood cell count (13,190 versus 15,960 cells/mm3, P = .09), and longer operative time (72 versus 89 minutes, P = .01). Patients who perforated had an increased length of stay and rate of complication. Conclusion: There was an overall increased rate of perforated appendicitis seen during quarantine compared with the previous year. Patients with perforated appendicitis had an increased length of stay, longer operative time, and increased rate of complications. Thus, although people were staying home due to public health safety orders, it negatively impacted those who developed appendicitis who may have presented to the hospital otherwise sooner.

Safety of adjustable gastric band conversion surgery: a systematic review and meta-analysis of the leak rate in 1- and 2-stage procedures.

BACKGROUND: Laparoscopic adjustable gastric banding has been a popular bariatric surgery in the United States since the early 2000s. Over the years, various long-term complications have prompted removal of these devices. To avoid subsequent weight gain, explanation of the gastric band is often followed by concomitant or staged conversion to another bariatric procedure. OBJECTIVE: It is our goal to evaluate the relative leak rate in 1- versus 2-stage adjustable gastric band conversion surgery. SETTING: Private teaching hospital, United States. METHODS: A search was performed in the PubMed/MEDLINE and Cochrane Library databases to evaluate literature regarding adjustable gastric band conversion procedures. After identification of publications that directly compared 1- and 2-stage laparoscopic adjustable gastric banding conversions, the Newcastle-Ottawa Quality Assessment Scale was used to determine if they would be used in our meta-analysis. The risk ratio for leak in 1- versus 2-stage conversions was then calculated. RESULTS: Our search yielded 483 publications. Twenty-five publications qualified for inclusion. The overall calculated risk ratio for leak in 1- versus 2-stage conversions was .90 (confidence interval [CI] .51-1.61, P = .73). Eight publications were found that discussed conversion from laparoscopic adjustable gastric banding to Roux-en-Y gastric bypass. The risk ratio for 1- versus 2-stage conversions for this subgroup was .82 (CI .35-1.93, P = .65). Eight publications were found that evaluated conversion to sleeve gastrectomy. The risk ratio of leak for 1- versus 2-stage conversions for these patients was 1.61 (CI .55-4.72, P = .39). CONCLUSIONS: Based on the results of this meta-analysis, there does not appear to be a significant difference in the overall leak rate between 1- and 2-stage adjustable gastric band conversions. The findings of our subgroup analysis suggest that there may be a safety advantage for 1-stage procedures when converting to Roux-en-Y gastric bypass and 2-stage procedures when converting to sleeve gastrectomy.

Endoscopic Decompression of Recurrent Sigmoid Volvulus in Pregnancy.

Sigmoid volvulus is a rare condition seen during pregnancy with high maternal and fetal morbidity and mortality. We report a case of a young 26-year-old woman, primipara, in her third trimester who presented with recurrent sigmoid volvulus at both 30 and 32 weeks of gestation. She underwent successful repetitive endoscopic decompression on both admissions with uneventful recovery. Endoscopic evaluation is safe in pregnancy and uncomplicated volvulus. It allows for diagnostic confirmation and assessment of complications; and it has successful outcomes in the presence of a multidisciplinary team.

Paraduodenal Pancreatitis: A Deceptive Abdominal Mass with Unique Histologic Findings.

Paraduodenal pancreatitis (PP) is an uncommon abdominal pathology characterized by scarring of the pancreaticoduodenal space. Diagnosis of this inflammatory process is challenging as its clinical presentation is similar to that of pancreatic cancer. Currently, no definitive radiologic or pathologic features have been established to permit diagnosis of PP without surgical resection. However, the presence of eosinophilic concretions has been reported with increasing frequency in the histologic evaluation of PP. To the best of our knowledge, these concretions are distinctive for PP and not reported in neoplasms commonly involving the pancreaticoduodenal space. Herein, we discuss the case of a 60-year-old man who was found to have PP after pancreaticoduodenectomy for a paraduodenal mass with an initially nondiagnostic biopsy. Retrospective review of the preoperative FNA samples revealed eosinophilic concretions like those found in the final surgical specimen. If the identification of eosinophilic concretions in a background of inflammatory changes was to be accepted as a diagnostic criterion for PP, patients such as ours could be spared the morbidity associated with surgical resection.

Diagnosis and Treatment of Metastatic Disease to the Pancreas.

Introduction: Metastatic disease to the pancreas is a rare entity from all malignant pancreatic masses. Its diagnosis is very challenging, but with the introduction of endoscopic ultrasound (EUS)-fine needle aspiration (FNA), now there is a feasible way to make an accurate histopathological and definitive diagnosis. Materials and Methods: This is a retrospective review of 11 patients with metastasis to the pancreas diagnosed with EUS-FNA in a tertiary referral center over a period of 3 years. We describe our institutional experience in diagnosing metastatic disease to the pancreas through EUS-FNA. Results: Between January 2015 and June 2018, 115 patients were diagnosed with pancreatic malignancy by EUS-FNA and only 11 (10%) with metastatic disease to the pancreas. Most common primary malignancy was renal cell carcinoma, followed by colon carcinoma, squamous/small cell carcinoma of the lung, and urothelial carcinoma. Five of 11 patients presented as a solitary pancreatic mass on initial imaging without any evidence of primary or metastatic disease elsewhere. Conclusions: In our experience, metastatic disease to the pancreas can represent up to 10% of solid pancreatic masses, which is lower compared to the reported incidence in previous literature. Our findings reveal that early identification and diagnosis help patient management and limit surgical morbidity and mortality.
