International Society of University Colon and Rectal Surgeons survey of surgeons' preference on rectal cancer treatment.

PURPOSE: Rectal cancer treatment has a wide range of possible approaches from radical extirpative surgery to nonoperative watchful waiting following chemoradiotherapy, with or without, additional chemotherapy. Our goal was to assess the personal opinion of active practicing surgeons on rectal cancer treatment if he/she was the patient. METHODS: A panel of the International Society of University Colon and Rectal Surgeons (ISUCRS) selected 10 questions that were included in a questionnaire that included other items including demographics. The questionnaire was distributed electronically to ISUCRS fellows and other surgeons included in our database and remained open from April 16 to 28, 2020. RESULTS: One hundred sixty-three specialists completed the survey. The majority of surgeons (n=65, 39.9%) chose the minimally invasive (laparoscopic) surgery for their personal treatment of rectal cancer. For low-lying rectal cancer T1 and T2, the treatment choice was standard chemoradiation+local excision (n=60, 36.8%) followed by local excision±chemoradiotherapy if needed (n=55, 33.7%). In regards to locally advanced low rectal cancer T3 or greater, the preference of the responders was for laparoscopic surgery (n=65, 39.9%). We found a statistically significant relationship between surgeons' age and their preference for minimally invasive techniques demonstrating an age-based bias on senior surgeons' inclination toward open approach. CONCLUSION: Our survey reveals an age-based preference by surgeons for minimally invasive surgical techniques as well as organ-preserving techniques for personal treatment of treating rectal cancer. Only 1/4 of specialists do adhere to the international guidelines for treating early rectal cancer.

COVID-19 and the Global Impact on Colorectal Practice and Surgery.

BACKGROUND: The novel severe acute respiratory syndrome coronavirus 2 virus that emerged in December 2019 causing coronavirus disease 2019 (COVID-19) has led to the sudden national reorganization of health care systems and changes in the delivery of health care globally. The purpose of our study was to use a survey to assess the global effects of COVID-19 on colorectal practice and surgery. MATERIALS AND METHODS: A panel of International Society of University Colon and Rectal Surgeons (ISUCRS) selected 22 questions, which were included in the questionnaire. The questionnaire was distributed electronically to ISUCRS fellows and other surgeons included in the ISUCRS database and was advertised on social media sites. The questionnaire remained open from April 16 to 28, 2020. RESULTS: A total of 287 surgeons completed the survey. Of the 287 respondents, 90% were colorectal specialists or general surgeons with an interest in colorectal disease. COVID-19 had affected the practice of 96% of the surgeons, and 52% were now using telemedicine. Also, 66% reported that elective colorectal cancer surgery could proceed but with perioperative precautions. Of the 287 respondents, 19.5% reported that the use of personal protective equipment was the most important perioperative precaution. However, personal protective equipment was only provided by 9.1% of hospitals. In addition, 64% of surgeons were offering minimally invasive surgery. However, 44% reported that enough information was not available regarding the safety of the loss of intra-abdominal carbon dioxide gas during the COVID-19 pandemic. Finally, 61% of the surgeons were prepared to defer elective colorectal cancer surgery, with 29% willing to defer for ≤ 8 weeks. CONCLUSION: The results from our survey have demonstrated that, globally, COVID-19 has affected the ability of colorectal surgeons to offer care to their patients. We have also discussed suggestions for various practical adaptation strategies for use during the recovery period.

Perioperative hypothermia during colectomy: when do patients get cold?

BACKGROUND: Hypothermia has been associated with an increase in the rate of infectious complications following colectomy. We hypothesized that a substantial fraction of temperature loss in patients undergoing elective colectomy occurs prior to operation. METHODS: Temperature data were collected from 105 consecutive patients undergoing elective colectomy at a single institution. RESULTS: The study population consisted of 105 patients; 67(64%) male, median age 59 years (range 17-95 years), median body mass index 27 kg/m2 (range 15-48 kg/m2). Median preoperative temperature was 36.7 °C (range 35.2-39.2 °C), dropping to 35.7 °C (range 34.0-37.3 °C) immediately following intubation and then rising to 36.2 °C (range 34.0-38.0 °C) prior to leaving the operating room. The median first postoperative temperature was 36.3 °C (range 34.4-37.7 °C). Temperatures were significantly different from one another (p < 0.05, ANOVA), except for the last operative and first postoperative temperature. A first postoperative temperature of ≥ 36.0 °C (meeting Surgical Care Improvement criteria Inf-10) was achieved in 78 (74%) of patients. A preoperative temperature of ≥ 36.5 °C was associated with a first postoperative temperature of ≥ 36.0 °C, but operative approach (laparoscopic versus open) was not. CONCLUSIONS: Most temperature loss occurs prior to operation in patients undergoing colectomy. Patients are rewarmed during the operative procedure. The time period prior to operation should be the focus of efforts designed to ensure normothermia.

Bowel Sounds Are Not Associated With Flatus, Bowel Movement, or Tolerance of Oral Intake in Patients After Major Abdominal Surgery.

BACKGROUND: Auscultation for bowel sounds has been advocated by some clinicians as a method to determine the resolution of postoperative ileus. OBJECTIVE: Our primary aim was to prospectively evaluate the relationships between bowel sounds and the ability to tolerate oral intake in patients after major abdominal surgery. Secondarily we aimed to evaluate relationships among bowel sounds, flatus and bowel movement, and oral intake. DESIGN: This was a prospective, blinded observational study. SETTINGS: The study was conducted at Western Pennsylvania Hospital. PATIENTS: A total of 124 adult patients undergoing major abdominal surgery were included. MAIN OUTCOME MEASURES: Data were collected by medical students blinded to the purpose of the study for 10 days postoperatively or until discharge, including the presence of bowel sounds (auscultation for 1 minute), flatus, bowel movement, and tolerance of oral intake (defined as ingestion of ≥1000 mL/24 h and each subsequent day without vomiting). Associations between paired variables were determined using ϕ coefficient testing. RESULTS: The study population consisted of 51 men and 73 women, with a mean age of 64 years (range, 20-92 y). The majority of patients (78/124 (63%)) underwent colorectal resection. The median length of hospital was 6 days. Bowel sounds were not associated with flatus, bowel movement, or tolerance of oral intake throughout the study period. The positive predictive value of bowel sounds in predicting flatus and bowel movement was low in the early postoperative period and remained <25% in predicting tolerance of oral intake throughout the study period. The analysis was repeated, including only those patients undergoing colorectal procedures, and was essentially unchanged. Flatus correlated with bowel movement in the first 6 days postoperation, but neither flatus nor bowel movement was associated with tolerance of oral intake. LIMITATIONS: The rate of tolerance of oral intake was relatively modest throughout the study period. CONCLUSIONS: Bowel sounds are not associated with flatus, bowel movement, or tolerance of oral intake after major abdominal surgery.

Colectomy for fulminant Clostridium difficile colitis: predictors of mortality.

The purpose of this study was to define clinical and radiographic variables associated with postoperative mortality after urgent colectomy for fulminant Clostridium difficile colitis. Data were obtained regarding patients undergoing colectomy for fulminant C. difficile colitis at two institutions (1997-2005). Univariate analysis of factors predicting 30-day mortality was performed using chi2 and Student's t tests. Multivariable logistic regression was done to include all variables whose P value was < 0.20. Clinical variables analyzed included: age, gender, recent operation, comorbidities, preoperative multisystem organ failure, vasopressors, symptom duration, time to surgery, serum albumin, change in serum albumin, serum creatinine, white blood cell count, and extent of colectomy. Computed tomography variables included: ascites, megacolon, and extent of colitis. Thirty-five patients (mean age 70 years, 46% male) underwent urgent colectomy for C. difficile colitis. The 30-day mortality rate was 45.7 per cent (16/35). The only clinical variable associated with mortality was preoperative multisystem organ failure (nonsurvivors 9/16 vs survivors: 4/19; P = 0.037). None of the three patients undergoing partial colectomy survived, although the difference in survival versus those undergoing subtotal colectomy was not significant. Patients with fulminant C. difficile colitis undergoing colectomy have a high mortality rate. Preoperative presence of multisystem organ failure was independently predictive of mortality.

"Peek port": a novel approach for avoiding conversion in laparoscopic colectomy.

BACKGROUND: This study aimed to assess the efficacy of a method for avoiding conversion to laparotomy in patients considered for laparoscopic colectomy. Patients deemed to be at high risk for conversion to laparotomy were initially approached via an 8-cm midline incision ("peek port") with the laparoscopic equipment unopened. If intraperitoneal conditions were favorable, the procedure was performed using hand-assisted laparoscopy. If intraperitoneal conditions were unfavorable, the incision was extended to a formal laparotomy. Patients deemed to be at low risk for conversion to laparotomy were approached laparoscopically from the outset. METHODS: Data from 241 consecutive patients brought to the operating room for intended laparoscopic colectomy were retrieved from a prospective database. RESULTS: The study population consisted of 132 men and 109 women with a mean age of 62 years and a mean body mass index (BMI) of 28. Prior abdominal surgery had been performed in 49% of these patients. Inflammatory conditions accounted for 38% of the diagnoses, and enteric fistulas were present in 7% of the cases. Of the 25 patients who underwent the initial "peek port," 8 (32%) underwent immediate incision extension to formal laparotomy. Hand-assisted laparoscopic colectomy was performed in 17 (68%) of these 25 patients, with one subsequent conversion to formal laparotomy. Of the 216 patients initially approached laparoscopically, 5 (2%) required conversion to laparotomy. The laparotomy rate for the "peek port" group (9/25, 36%) was higher than for the initial laparoscopy group (5/216, 2%) (p < 0.0001). Of the 233 patients from both groups who underwent laparoscopy, the overall rate for conversion to laparotomy was 3% (6/233). CONCLUSIONS: The "peek port" approach to the patient with a potentially hostile abdomen allows for rapid assessment of intraperitoneal conditions and is associated with an overall low rate of conversion from laparoscopy to laparotomy. This technique should reduce overall cost by avoiding the use of laparoscopic equipment as well as potential complications related to trocar placement and laparoscopic dissection in patients who will ultimately require formal laparotomy.

Effect of immunosuppression on patients undergoing bariatric surgery.

BACKGROUND: Immunocompromised patients are at high risk of medical complications. Immunosuppression might be a relative contraindication to bariatric surgery. We describe our experience with immunosuppressed patients undergoing bariatric surgery and review the safety, efficacy, results, and outcomes. METHODS: We performed a retrospective review of prospectively collected data. All patients taking long-term immunosuppressive medications or with a diagnosis of an immunosuppressive condition were included in this study. Data on weight loss, co-morbidities, complications, and postoperative immunosuppression were collected. RESULTS: From July 1999 to February 2008, 1566 patients underwent bariatric surgery. Of these 1566 patients, 61 (3.9%) were taking immunosuppressive medications or had an immunosuppressive condition. Of these 61 patients, 49 were taking immunosuppressive medications for asthma, autoimmune disorders, endocrine deficiency, or chronic inflammatory disorders. The medications included oral, inhaled, and topical glucocorticoids for 39 patients and other immunosuppressive or disease-modifying antirheumatic drugs for 24 patients. The bariatric procedures included laparoscopic Roux-en-Y gastric bypass in 55, laparoscopic revisional procedures in 5, and laparoscopic sleeve gastrectomy in 1. No patient died perioperatively. A total of 26 complications occurred in 20 patients. The average percentage of excess weight loss was 72% (range 20-109%) at 1 year postoperatively. At a median postoperative follow-up of 18 months (range 2-68.6), 25 (51%) of 49 patients no longer required immunosuppressive medications owing to improvement of their underlying disease. Obesity-related health problems (diabetes mellitus, hypertension, obstructive sleep apnea, gastroesophageal reflux disease, asthma) had resolved or improved in 80-100% of patients. CONCLUSION: The results of our study have shown that immunocompromised patients can safely undergo bariatric surgery with good weight loss results and improvement in co-morbidities. A large percentage of patients were able to discontinue immunosuppressive medications postoperatively.

Technical skills assessment as part of the selection process for a fellowship in minimally invasive surgery.

INTRODUCTION: Selection of candidates for surgical fellowships has traditionally been based on subjective evaluations by the program directors and references from previous positions. The introduction of well-validated objective methods of assessment has allowed us to evaluate candidates' technical skills and base the selection process on objective, reliable, and transparent criteria. The aim of the study was to assess the applicability of such methods in current practice. MATERIALS AND METHODS: Prospective study. Eight surgeons, applying for a fellowship position in minimally invasive surgery (MIS), performed a previously validated assessment curriculum using a Virtual-Reality Laparoscopic Trainer (LapSim 3.0, Surgical Science, Gothenburgh, Sweden). Technical performance was evaluated using criteria registered by the simulator, i.e., time, error score, and efficiency of movements score. Candidates performed all the tasks in easy end medium level until reaching predefined criteria. If proficiency criteria were not achieved on easy or medium level after nine repetitions the test was considered as failed. Additionally, all applicants underwent an interview by two independent attending surgeons. Each applicant received a grade on a ten-point scale. RESULTS: Five out of the eight candidates failed the technical skills assessment test. One candidate failed to achieve proficiency criteria on easy level, one on medium, and three on difficult level. Evaluation scores, based on the interview of the candidates showed a good interrater reliability (Cronbach's alpha = 0.8). There was no significant correlation between the interviewers rating, and the applicants technical skills demonstrated during the test on the VR trainer (Spearman's rho = 0.182, p = 0.696). CONCLUSIONS: Evaluations by senior surgeons are reproducible and reliable. The introduction of technical skills assessment has the potential to improve the current method of candidate selection, making it more valid, objective, and transparent.

Obesity surgery and malignancy: our experience after 1500 cases.

BACKGROUND: Obesity is a risk factor for cancer and is associated with increased mortality from a number of malignancies. We describe our experience with bariatric surgery patients with a history of malignancy and review the safety and outcomes of bariatric surgery in patients with a history of cancer. METHODS: We performed a retrospective review of prospectively collected data from all patients diagnosed with a malignancy before, during, or after bariatric surgery. Data on weight loss, co-morbidities, and recurrence were collected. RESULTS: From July 1999 to February 2008, 1566 patients underwent bariatric surgery. Of these 1566 patients, 36 (2.3%) had a history of malignancy before they underwent bariatric evaluation and surgery, 4 (0.26%) were diagnosed with a malignancy during their preoperative evaluation, 2 of whom subsequently underwent bariatric surgery, and 2 had intraoperative findings suspicious for malignancy; bariatric surgery was completed in both cases. The evaluation revealed renal cell carcinoma and low-grade lymphoma, respectively. No procedures were aborted because of a suspicion of malignancy. Postoperatively, 16 patients (0.9%) were diagnosed with cancer, 3 of whom had a history of malignancy: 1 with metastatic renal cell, 1 with recurrent melanoma, and 1, who had had prostate cancer, with bladder cancer. CONCLUSION: A history of malignancy does not appear to be a contraindication for bariatric surgery as long as the life expectancy is reasonable. Screening for bariatric surgery might reveal the malignancy. Bariatric surgery does not seem to have a negative effect on the treatment of malignancies that are discovered in the postoperative period.

Portal vein thrombosis after laparoscopic splenectomy for systemic mastocytosis: a case report and review of the literature.

INTRODUCTION: Laparoscopic splenectomy has become the surgical procedure of choice for various diseases of the spleen. Portal vein thrombosis (PVT) after splenectomy occurs in 0.5% to 22% of patients. Symptoms are nonspecific and include fever, abdominal pain, and epigastric distress. Risk factors for PVT after splenectomy include underlying hematologic disorders, massive splenectomy, and other hypercoagulable states. METHODS: We describe a case of PVT in a woman who underwent laparoscopic splenectomy for symptomatic splenomegaly secondary to systemic mastocytosis. The patient was discharged from the hospital without anticoagulation and experienced nonspecific symptoms beginning 10 days postoperatively. Diagnosis of PVT was made by contrast-enhanced abdominal computed tomography. The patient had no underlying risk factors. Anticoagulation treatment facilitated recanalization of the portal vein and this was verified by Doppler ultrasound at follow-up. CONCLUSIONS: PVT after laparoscopic splenectomy is not uncommon. Signs and symptoms are vague and require a high index of suspicion for timely diagnosis. Anticoagulation is the treatment of choice and allows recanalization of the portal system in the majority of cases.

Laparoscopic colectomy for apparently benign colorectal neoplasia: A word of caution.

PURPOSE: Endoscopically unresectable apparently benign colorectal polyps are considered by some surgeons as ideal for their early laparoscopic colectomy experience. Our hypotheses were: (1) a substantial fraction of patients undergoing laparoscopic colectomy for apparently benign colorectal neoplasia will have adenocarcinoma on final pathology; and (2) in our practice, we perform an adequate laparoscopic oncological resection for apparently benign polyps as evidenced by margin status and nodal retrieval. METHODS: Data from a consecutive series of patients undergoing laparoscopic colectomy (on an intention-to-treat basis) for endoscopically unresectable neoplasms with benign preoperative histology were retrieved from a prospective database and supplemented by chart review. RESULTS: The study population consisted of 63 patients (mean age 67, mean body mass index 29). Two out of 63 cases (3%) were converted to laparotomy because of extensive adhesions (n = 1) and equipment failure (n = 1). Colectomy type: right/transverse (n = 49, 78%); left/anterior resection (n = 10, 16%); subtotal (n = 4, 6%). Invasive adenocarcinoma was found on histological analysis of the colectomy specimen in 14 out of 63 cases (22%), standard error of the proportion 0.052. Staging of the 14 cancers were I (n = 6, 43%), II (n = 3, 21%), III ( = 4, 29%), and IV (n = 1, 7%). The median nodal harvest was 12 and all resection margins were free of neoplasm. Neither dysplasia on endoscopic biopsy nor lesion diameter was predictive of adenocarcinoma. Eight out of 23 (35%) patients with dysplasia on endoscopic biopsy had adenocarcinoma on final pathology versus 6/40 (15%) with no dysplasia (p = 0.114, Fisher's exact test). Mean diameter of benign tumors was 3.2 cm (range 0.5-10.0cm) versus 3.9cm (range 1.5-7.5cm) for adenocarcinomas (p = 0.189, t - test). CONCLUSION: A substantial fraction of endoscopically unresectable colorectal neoplasms with benign histology on initial biopsy will harbor invasive adenocarcinoma, some of advanced stage. This finding supports the practice of performing oncological resection for all patients with endoscopically unresectable neoplasms of the colorectum. The inexperienced laparoscopic colectomist should approach these cases with caution.

A three-decade review of thermal injuries among the elderly at a regional burn centre.

AIM: To review trends in incidence and treatment of thermal injuries among the elderly. METHOD: A 3-year retrospective review of medical records of people aged 65 years and older admitted to our burn centre over July 2003-June 2006. RESULTS: Elderly people with burns continued to have significant comorbidities. They were often burned because they were inappropriately trying to live alone. Thus discharge was often complicated. CONCLUSIONS: At our burn centre, survival among elderly people with burns has increased, probably as a result of more sophisticated medical, surgical and nursing care, as well as more extensive rehabilitation.

Prevalence of Helicobacter pylori infection and value of preoperative testing and treatment in patients undergoing laparoscopic Roux-en-Y gastric bypass.

BACKGROUND: Previous studies have reported a high prevalence of Helicobacter pylori infection in patients undergoing Roux-en-Y gastric bypass (RYGB) and a greater incidence of anastomotic ulcer in patients positive for H. pylori, leading to recommendations for routine preoperative screening. Our hypotheses were that the prevalence of H. pylori in patients undergoing RYGB is similar to that of the general population and that preoperative H. pylori testing and treatment does not decrease the incidence of anastomotic ulcer or pouch gastritis. METHODS: A retrospective analysis of H. pylori serology, preoperative and postoperative endoscopy findings, and the development of anastomotic ulcer or erosive pouch gastritis was performed. All patients positive for H. pylori received treatment. Univariate parametric and nonparametric statistical tests, as well as multiple logistic regression analyses, were performed. RESULTS: A total of 422 LRYGB patients were included in the study. Of these patients, 259 (61.4%) were tested for H. pylori and 163 (38.6%) were not. Of the 259 patients, 58 (22.4%) tested positive for H. pylori, 197 (76.1%) tested negative, and 4 (1.5%) had an equivocal result. Postoperatively, 53 patients (12.6%) underwent upper endoscopy. Of these 53 patients, 19 (4.5%) had positive endoscopy findings for anastomotic ulcer (n = 16) or erosive pouch gastritis (n = 3). Five patients underwent biopsy at endoscopy; all biopsies were negative for H. pylori. No difference was found in the rate of positive endoscopy between patients tested preoperatively for H. pylori (5%) and patients not tested (3.7%). CONCLUSION: The results of our study have shown that the prevalence of H. pylori infection in patients undergoing RYGB is similar to that of the general population. Our study has shown that H. pylori testing does not lower the risk of anastomotic ulcer or pouch gastritis.

Intraoperative death due to thrombotic thrombocytopenic purpura (TTP)-related acute myocardial failure in a patient undergoing laparoscopic splenectomy.

Thrombotic thrombocytopenic purpura (TTP) is an uncommon disorder characterized by a pentad of microangiopathic hemolytic anemia, thrombocytopenia, renal dysfunction, fever, and a fluctuating neurologic syndrome. Splenectomy is performed for patients who are refractory to plasma therapy and for relapsing TTP. We describe a case of a patient who died due to intramyocardial hemorrhage after undergoing laparoscopic splenectomy for TTP resistant to treatment with plasmapheresis. A 52-year-old woman was admitted with ecchymoses, low platelet count, weakness of left face and upper extremity, and a presumptive diagnosis of TTP. Vital signs were stable. White blood count was 7800/microL, hemoglobin 7.9 g/dL, and platelet count of 13,000/microL. Her basic metabolic panel and liver function tests were normal. Further laboratory workup confirmed the diagnosis of TTP. The patient was initially treated with plasmapheresis and high dose steroid therapy but underwent an emergent laparoscopic splenectomy due to refractory TTP. At the end of the uneventful procedure, the patient suffered a cardiac arrest and died. Autopsy concluded that the death was from myocardial failure due to extensive myocardial hemorrhage secondary to TTP. There are several published case reports of sudden death due to cardiac involvement in TTP. However, intraoperative mortality is not reported. We conclude that TTP-related acute heart failure may represent an extremely important clinical risk in these patients who are undergoing surgery.

Occult perineal endometrioma diagnosed by endoanal ultrasound and treated by excision: a report of 3 cases.

BACKGROUND: Isolated perineal endometrioma is a rare entity and often causes diagnostic uncertainty. CASES: Three premenopausal women, none with a prior history of endometriosis, presented with vague perineal pain 3-6 months following obstetric delivery with episiotomy. The latency periods between the onset of symptoms and definitive diagnosis were 3 months, 18 months and 3 years despite multiple physician evaluations in the interim. Patient presentation and management were virtually identical in all cases. Detailed questioning revealed that the pain was located adjacent to the episiotomy incision and waxed and waned with menses. Physical examination revealed a vague fullness adjacent to the episiotomy incision. Endoanal ultrasound revealed a mass of mixed echogenicity adjacent to the external anal sphincter. Transperineal exploration revealed a tumor with the gross appearance of an endometrioma, which was confirmed histologically. Excision of the mass with preservation of the anal sphincter muscle resulted in resolution of symptoms in all patients without the need for hormonal manipulation. No patient suffered diminution of fecal continence. CONCLUSION: Occult perineal endometriosis should be considered when a woman presents with cyclic pain in the perineum following delivery and episiotomy. Endoanal ultrasound can assist with the diagnosis. Transperineal excision with sparing of the anal sphincter can be curative, without compromising continence.

Rectosigmoidectomía perineal en el tratamiento del prolapso rectal completo / Perineal rectosigmoidectomy for the treatment of complete rectal prolapse

Antecentes: El tratamiento quirúrgico del prolapso rectal completo es controvertido. Se han descrito técnicas abdominales y perineales. La rectosigmoidectomía perineal (RSP) como tratamiento en el prolapso rectal completo. Lugar de aplicación: Hospital universitario. Diseño: retrospectivo, observacional. Población: 98 pacientes con prolapso rectal completo operados entre 1985 y 2005. Método: Análisis retrospectivo y descriptivo de los pacientes con prolapso rectal completo sometidos a una RSP en un Servicio de Coloproctología. Resultados: Se realizaron 106 cirugías en 98 pacientes (79 mujeres y 19 varones, edad promedio: 78 años). El seguimiento postoperatorio fue de 11 a 101 meses. El 72 por ciento presentaban incotinencia preoperatoria. En los primeros 30 pacientes la rectosigmoidectomía perineal se realizó sin la plástica del elevador, mientras que esta se utilizó en los siguientes, como parte del procedimiento. La incontinencia mejoró en el 43 por ciento y 84 por ciento respectivamente (P = 0,01). La estadía media intrahospitalaria fue de 3,5 días. La morbilidad postoperatoria fue del 14 por ciento: 3 hemorragias postoperatorias, 2 infecciones, 1 estenosis, 4 internaciones en UTI y 5 misceláneas. La mortalidad fue nula. El porcentaje de readmisión a los 30 días fue del 3 por ciento. La recidiva fue del 13,2 por ciento (n = 15). En 8 casos se repitió el procedimiento, en 2 resección/pexia y en 1 caso rectopexia con malla. Cuatro pacientes no se reoperaron. Conclusión: La RSP es un procedimiento seguro y efectivo en el tratamiento del prolapso rectal completo. La adición de una plástica del elevador al procedimiento mejora la incontinencia que suele presentarse en estos pacientes.

Laparoscopic transgastric endoscopy after Roux-en-Y gastric bypass.

BACKGROUND: Access and endoscopic evaluation of the bypassed stomach is difficult after laparoscopic Roux-en-Y gastric bypass. We propose a minimally invasive technique to access the bypassed stomach after Roux-en-Y gastric bypass for endoscopic diagnosis and treatment. METHODS: First, we established carbon dioxide pneumoperitoneum to a pressure of 12-15 mm Hg. Next, 12-mm umbilical, 5-mm right upper quadrant, 5-mm left lower quadrant, and 15-mm left upper quadrant trocars were placed. A purse-string suture was placed on the anterior wall of the stomach. A gastrotomy was made using ultrasonic shears and the 15-mm trocar was placed into the stomach. The endoscope was then inserted through the 15-mm trocar, and the pneumoperitoneum was decreased to 10 mm Hg. Once the evaluation was complete, the gastrotomy was closed with a running suture or linear stapler. RESULTS: Ten patients at our institution have undergone laparoscopic transgastric endoscopy. Five patients had biliary pathologic findings. Four of these patients underwent successful endoscopic retrograde cholangiopancreatography and papillotomy; the procedure in the fifth patient was unsuccessful because stone impaction at the ampulla. Three patients were evaluated for gastrointestinal bleeding. One was diagnosed with a duodenal gastrointestinal stromal tumor, one with a bleeding duodenal ulcer, requiring surgical exploration; and the third had negative endoscopy findings. Two patients evaluated for chronic abdominal pain had negative endoscopy findings. No complications developed. CONCLUSIONS: Laparoscopic transgastric endoscopy is a safe and minimally invasive approach for the evaluation of the gastric remnant, duodenum, and biliary tree in patients who have undergone Roux-en-Y gastric bypass.
